+2007-05-17 08:44  oetiker

+

+         src/rrd_open.c, src/rrd_update.c: added posix_fadvise support
+         (untested) ... this should help performance by stopping read-ahead
+         and droping buffer cache for all rrd data except the file header
+         portion. Newly created files are fdsynced to disk and released
+         from cache after creation, to soften the blow on buffer cache by
+         creating new rrds.

+         compiled in ...
+
+2007-05-08 15:10  oetiker
+
+       * bindings/Makefile.am: ruby complained about finding a previous
+         copy of the rrdtool extension ... very odd thing actually ...
+         adding RUBYARCHDIR= seems to help ...
+
+2007-05-06 19:38  oetiker

+                   GNU GENERAL PUBLIC LICENSE
+                      Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for non-commercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                    END OF TERMS AND CONDITIONS

+
+ I want specified Free/Libre and Open Source Software ("FLOSS")
+ applications to be able to use specified GPL-licensed RRDtool
+ libraries (the "Program") despite the fact that not all FLOSS licenses are
+ compatible with version 2 of the GNU General Public License (the "GPL").
+ 
+ As a special exception to the terms and conditions of version 2.0 of the GPL:
+
+ You are free to distribute a Derivative Work that is formed entirely from
+ the Program and one or more works (each, a "FLOSS Work") licensed under one
+ or more of the licenses listed below, as long as:
+
+   1. You obey the GPL in all respects for the Program and the Derivative
+   Work, except for identifiable sections of the Derivative Work which are
+   not derived from the Program, and which can reasonably be considered
+   independent and separate works in themselves,
+
+   2. all identifiable sections of the Derivative Work which are not derived
+   from the Program, and which can reasonably be considered independent and
+   separate works in themselves,
+
+         1. are distributed subject to one of the FLOSS licenses listed
+         below, and
+
+         2. the object code or executable form of those sections are
+         accompanied by the complete corresponding machine-readable source
+         code for those sections on the same medium and under the same FLOSS
+         license as the corresponding object code or executable forms of
+         those sections, and
+
+   3. any works which are aggregated with the Program or with a Derivative
+   Work on a volume of a storage or distribution medium in accordance with
+   the GPL, can reasonably be considered independent and separate works in
+   themselves which are not derivatives of either the Program, a Derivative
+   Work or a FLOSS Work.
+
+ If the above conditions are not met, then the Program may only be copied,
+ modified, distributed or used under the terms and conditions of the GPL.

+RRDTOOL NEWS
+============
+Major Changes between 1.0.x and 1.2.x
+
+Graphing
+--------
+
+* rewritten graphics generation based on libart.
+  - anti-aliased output
+  - alpha transparency support
+  - truetype fonts
+ 
+* additional graphics formats: EPS, PDF, SVG
+
+* extended multi-part documentation
+
+* VDEF support; define and use variables.  Find, and use, the
+  maximum rate seen by rrdtool; compute and show the average
+
+* Sliding window (trend) analysis
+  Compute a smoother average, for instance over the last 6 CDPs
+
+* percentile (95th or other)
+  Remove peaks, 95 percent of all rates are at or below the
+  returned value
+
+Logging
+-------
+* a second logging interface: rrdtool updatev
+  Verbose updating of the database; show CPDs being created
+
+* Aberrant Behavior Detection with Holt-Winters Forecasting
+  Compare current data with expected data, detect and log when
+  the rates are outside expected levels
+
+* COMPUTE data type for artificial data-sources calculating their
+  input using RPN math and data from the other data-sources.
+ 
+Incompatibilities
+-----------------
+* Colons in COMMENT arguments to rrdtool graph must be escaped with a backslash
+
+* the --alt-y-mrtg option is gone or rather since 1.2.7 it is back but
+  without functionality.
+
+* In pipe mode, rrdtool answers with OK only if it was successful with the
+  command. Otherwhise the answer will be ERROR...
+
+
+Behind the Scenes
+-----------------
+* In order to support Holt-Winters and Calculated Datasources,
+  the rrdtool data format has changed. While the new version of rrdtool can
+  read files created with rrdtool 1.0.x. It is not possible to read files
+  created by rrdtool-1.2.x with rrdtool-1.0.x
+
+* External libraries are not included with rrdtool anymore. This is in line
+  with todays trend of using shared libraries everywhere. With the exception
+  of the cgi library most things required by rrdtool will be found on every recent
+  system.
+
+* Memory Mapped IO support for faster logging.

+Round Robin Database Tools
+==========================
+
+It is pretty easy to gather status information from all sorts of things,
+ranging from the temperature in your office to the number of octets which
+have passed through the FDDI interface of your router. But it is not so
+trivial to store this data in a efficient and systematic manner. This is
+where RRDtool kicks in. It lets you log and analyze the data you gather from
+all kinds of data-sources (DS). The data analysis part of RRDtool is based
+on the ability to quickly generate graphical representations of the data
+values collected over a definable time period.
+
+
+To compile:
+-----------
+
+check out the instructions in doc/rrdbuild.txt
+
+Getting Started:
+----------------
+
+Either after compiling or after installing you can try the example
+RRDtool applications in the examples directory.
+
+To learn:
+---------
+
+Read the documentation in the doc directory. Start of with
+RRDtool. All documents are available as html and as ASCII text.  
+
+If you are looking for a more slow paced introduction, make sure to read
+Alex van den Bogaerdt's rrdtutorial which is also available from the doc
+directory. Also read his cdeftutorial and Steve Rader's rpntutorial.
+ 
+If you want to know about the format of the log files check
+src/rrd_format.h there are a lot of comments in there ...
+
+How to make Tobi happy:
+-----------------------
+
+If you want to show your appreciation for RRDtool you could make me happy
+by going to http://tobi.oetiker.ch/wish and ordering a CD from
+my CD wish list ... 
+
+
+How to keep in touch:
+---------------------
+
+There are 3 Mailing lists for RRDtool:
+
+rrd-announce   LOW volume RRDtool Announcements List (Only Stable Releases)
+rrd-users       For discussion amongst people who use RRDtool in their applications
+rrd-developers  For people who actually HACK RRDtool code
+
+To subscribe to <MAILGLIST> send a message with the subject 'subscribe'
+to <MAILGLIST>-request@lists.oetiker.ch
+
+Note, that postings to rrd-announce will always be cross-posted 
+to rrd-users and rrd-developers as well.
+
+To Contribute:
+--------------
+
+Contributed feature and bug patches are most welcome. But please
+send complete patches. A complete patch patches the CODE as well
+as the CHANGES, CONTRIBUTORS and the POD files.
+
+Use GNU   diff --unified --recursive olddir newdir   to build your patches.
+
+The latest Version:
+-------------------
+Is available from http://oss.oetiker.ch/rrdtool/

+In order to use the librrd in multi-threaded programs you must:
+
+  * Link with librrd_th instead of with librrd
+  * Use the *_r function instead or the *-functions
+  * Never use non *_r functions unless it is explicitly documented that the 
+    function is tread-safe
+
+Every thread SHOULD call rrd_get_context() before the first call to
+any librrd function in order to set up thread specific data. This is
+not strictly required, but it is the only way to test if memory
+allocation can be done by this function. Otherwise the program may die
+with a SIGSEGV in a low-memory situation.
+
+
+IMPORTANT NOTE FOR RRD CONTRIBUTORS:
+
+Some precautions must be followed when developing rrd from now on:
+
+* Only use thread-safe functions in library code. Many often used libc
+  functions aren't thread-safe. Take care if you want to use any of
+  the following functions:
+
+    + direct strerror calls must be avoided: use rrd_strerror instead,
+      it provides a per-thread error message
+    + the getpw*, getgr*, gethost* function families (and some more get*
+      functions): use the *_r variants
+    + Time functions: asctime, ctime, gmtime, localtime: use *_r variants
+    + strtok: use strtok_r
+    + tmpnam: use tmpnam_r
+    + many other (lookup documentation)
+
+As an aide(?) a header file named "rrd_is_thread_safe.h" is provided
+that works with the GNU C-preprocessor to "poison" some of the most
+common non-thread-safe functions using the "#pragma GCC poison"
+directive. Just include this header in source files you want to keep
+thread-safe.
+    
+* Do not introduce global variables!
+
+  If you really, really have to use a global variable you may add a 
+  new field to the rrd_context structure and modify rrd_error.c,
+  rrd_thread_safe.c and rrd_non_thread_safe.c
+
+* Do not use "getopt" or "getopt_long" in *_r (directly or indirectly)
+
+  getopt uses global variables and behaves badly in a multithreaded
+  application when called concurrently. Instead provide a *_r function
+  taking all options as function parameters. You may provide argc and
+  **argv arguments for variable length argument lists. See
+  rrd_update_r as an example. 
+
+* Do not use the parsetime function!
+
+  It uses lots of global vars. You may use it in functions not

+
+WIN32 Platform Note (added 04/01/03):
+
+Both rrdtool.vcproj (MSVC++ 7.0) and rrd.dsw (MSVC++ 6.0) are configured to compile with rrd_thread_safe_nt.c.

+
+7/29/04 Jake Brutlag
+
+As of Jan 2004, code for libraries utilized by rrdtool 
+(png, libart, freetype, and zlib) is no longer distributed with
+rrdtool. This requires some changes to the compile process on
+Win32. The solution described here is to compile rrdtool to
+link against these libraries dynamically. There is an advantage
+to this approach: namely the rrdtool distribution doesn't have to
+worry about how to compile these libraries on Win32. In theory,
+since others already provide and maintain Win32 binaries for these
+libraries the users don't have to worry about how to compile them
+either. The disadvantage of this approach is that the DLLs for
+these libraries must be available on the hosts where rrdtool will run.
+
+Here are step by step instructions for compiling rrdtool.exe and
+the perl shared library (RRDS.dll) with Microsoft Visual C++ 6.0.
+(1) Download libraries rrdtool depends on from GnuWin32:
+http://gnuwin32.sourceforge.net/
+For freetype, libpng, and zlib download the "Complete Package"; each of
+these will be a self-extracting self-installing executable.
+For libart, download both the "Binaries" and "Developer Files" packages.
+Unfortunately at this time GnuWin32 doesn't provide the "Complete Package"
+installer for libart. Perhaps by the time you are following these
+instructions GnuWin32 will have a "Complete Package" for libart.
+(2) Install the GnuWin32 libraries by running the executables for freetype,
+libpng, and zlib. These instructions and the Visual C++ project files
+distributed with rrdtool assume that you will use the default install
+location: C:\Program Files\GnuWin32. Extract the two zip files for libart,
+libart-2.3.3-bin.zip and libart-2.3.3-1-lib.zip into the GnuWin32 directory;
+the appropriate libart files will be added to the include, lib, and bin
+subdirectories.
+(3) Add C:\Program Files\GnuWin32\bin to the PATH (Control Panel ->
+System -> Advanced -> Environment Variables).
+(4) Start Microsoft Visual C++ 6.0. Load the workspace file, rrdtool.dsw,
+from the src subdirectory of your rrdtool code directory.
+(5) Compile the Release build of the rrdtool project (since rrdtool depends
+on the rrd project, the rrd library will also be compiled). At this
+time, the compile will fail in zconf.h, a zlib header file. The problem
+is a preprocessor directive that loads unistd.h. Open zconf.h in VC++
+(this file is in C:\Program Files\GnuWin32\include) and find the following
+code block:
+
+#if 1           /* HAVE_UNISTD_H -- this line is updated by ./configure */
+#  include <sys/types.h> /* for off_t */
+#  include <unistd.h>    /* for SEEK_* and off_t */
+#  ifdef VMS
+#    include <unixio.h>   /* for off_t */
+#  endif
+#  define z_off_t  off_t
+#endif 
+
+Change it to reads as follows (this is code from zlib-1.1.4):
+
+#if HAVE_UNISTD_H
+#  include <sys/types.h> /* for off_t */
+#  include <unistd.h>    /* for SEEK_* and off_t */
+#  ifdef VMS
+#    include <unixio.h>   /* for off_t */
+#  endif
+#  define z_off_t  off_t
+#endif 
+
+Note that it is actually just a one line change. Save the file and
+recompile rrdtool. By the time you are following these instructions
+this issue with zconf.h may be resolved.
+(6) At this point, you can run the executable rrdtool.exe in the
+src\toolrelease subdirectory. Note that if you wish to run rrdtool
+on other machines, you will need the following DLLs installed (on the
+path) on those machines:
+zlib1.dll
+libpng12.dll
+libart_lgpl.dll
+freetype6.dll
+msvcrt.dll
+The names of the first four DLLs might vary from what is listed here
+depending on the versions of the packages you downloaded from GnuWin32.
+The fifth DLL, msvcrt.dll, is a system DLL for most versions of Windows.
+If you are running on old version of Windows, you can install/upgrade to
+IE4.0 to get this DLL.
+(7) To compile the perl-shared library, open a Command Prompt (DOS box)
+and cd to the bindings\perl-shared subdirectory.
+(8) Run vcvars32.bat; this batch file, in your vc98\bin directory will
+set necessary environment options for command line compiling.
+(9) In bindings\perl-shared, run
+perl ntmake.pl
+nmake
+nmake test
+If nmake test succeeds, you are good to go. RRDs.dll is in 
+blib\arch\auto\RRDs. If you plan to install via the Active State ppm
+tool, tar and gzip the blib directory. You can use the RRDs.ppd file
+in bindings\perl-shared directory. Remember that as in the case of
+rrdtool.exe you will need the DLLs listed in (6) on the machine where
+you are going to use RRDs.dll.
+
+Microsoft Visual C++ 7.1 (.NET 2003):
+
+Unfortunately, this is more difficult than with VC++ 6.0. The problem
+is that by default the C runtime dll for VC++ 7.1 is msvcr71.dll rather
+than msvcrt.dll. The GnuWin32 library binaries are all compiled
+to use msvcrt.dll and you can't mix msvcr71.dll and msvcrt.dll in the
+same process. One option is to download the source code for the libraries
+(available from http://gnuwin32.sourceforge.net) recompile them with
+VC++ 7.l. Then all the components will use msvcr71.dll. Once you are
+going to go this route, you can also use static multi-threaded libraries
+and use static linking between rrdtool (or RRDs.dll) and its dependencies.
+
+To use the GnuWin32 library binaries, you need to trick VC++ 7.1 into
+compiling rrdtool to use the older msvcrt.dll. Follow steps (1) - (3)
+as above, then:
+(4) Obtain a different version of the msvcrt.lib import library that
+is compatible with vc7 and points to msvcrt.dll:
+msvcrtlib_for_vc7.zip from http://xchat.org/win32/testing
+Backup msvcrt.lib in your vc7\lib directory 
+(\Program Files\Microsoft Visual Studio .NET 2003\vc7\lib)
+Then extract the msvcrt.lib from the zip file into the vc7\lib directory.
+WARNING: Use this msvcrt.lib at your own risk! This is not a Microsoft
+supplied file nor a file supported by anyone associated with rrdtool.
+(5) Start Microsoft Visual C++ 7.1. Load the solution file, rrdtool.sln,
+from the src subdirectory of your rrdtool code directory. Edit zconf.h,
+as needed, as described under (5) above. Compile the release build of
+the rrdtool project.
+Proceed with steps (6) - (9) as above, if you are using/picking up
+the wrong msvcrt.lib import library then nmake test for perl-shared
+will fail.
+
+Note: it is possible in the future that GnuWin32 will provide Win32
+binaries that utilize msvcr71.dll rather than msvcrt.dll.
+
+5/14/02 Jake Brutlag
+
+These notes share some insight I gained compiling 1.1.x with
+MS Visual C++ 6.0 (using project files). This information may or
+may not be accurate at the time you are reading this.
+
+(1) freetype and rrdtool cannot use precompiled headers (which are
+enabled by default for MSVC++ projects).  MSVC++ 6.0 does not
+support precompiled headers if #include directives contain MACROS.
+(2) Compile Release build with Default optimization, not the
+Maximize Speed optimization. I encountered some strange errors
+(related to argument processing for complex commands like graph--
+perhaps the getopt stuff is too blame) with Maximize Speed.
+(3) libart relies upon config.h (ostensibly generated by the
+configure script-- but of course not on Win32 platforms). ..\..\confignt
+(which contains a static Win32 version of config.h) should be on
+the include path.
+(4) Fonts are located in the %windir%\fonts, so the default font
+is c:\winnt\fonts\cour.ttf. (6/19/02) At Kerry Calvert's suggestion
+this setting was moved to confignt\config.h.
+(5) libart requires a custom build step to generate art_config.h; this
+is done manually via the commands:
+cl -I..\..\confignt gen_art_config.c
+gen_art_config.exe > art_config.h
+
+Currently, to compile rrd.lib and rrdtool.exe using
+the MSVC++ project files, first start MSVC++ 6.0. Open the rrdtool
+workspace (rrdtool.dsw in the src directory). The active project/
+configuration should be rrdtool-Win32 Release. Select Rebuild All
+from the Build menu. The static link library (rrd.lib) will
+be generated in src\release directory and executable will be generated
+in the src\toolrelease directory.
+
+Compiling RRDtool on NT ... work in progress
+---------------------------------------------------------------
+                         by Tamas Kovacshazy (khazy@mit.bme.hu)
+
+Persisting Problems with the current NT port:
+
+Unfortunately, the RRD perl modules does not work with Perl
+(ActivePerl) using the current distribution.
+
+The RRD shared perl module can be compiled after some
+modification...
+
+Follow these steps:
+
+0. Install perl if you do not have it!
+   Visit http://www.ActiveState.com/pw32/ for a complete distribution.
+
+1. Copy ..\gd1.2\release\gd.lib  to ..\gd1.2\
+2. Copy ..\src\release\rrd.lib to ..\src
+3. perl Makefile.pl
+
+In this step the system complains about something I do not
+understand. The error message is the following:
+
+Note (probably harmless): No library found for '-lm'
+
+Is a library missing? But it does not stop with an error...
+
+4. nmake test (You must have Visual C++ on the machine!)
+
+After these steps it generates the test files (svgs and rrds),
+and they seem to be good.
+
+The real problem in the shared perl modul is the following:
+
+I do not know how this installation stuff works. The problem is
+that the installation stuff looks for the gd.lib and the
+rrd.lib in the ..\gd1.2 and ..\src directory. The UNIX compile
+puts the files into these directories, but the NT compile does
+not.
+
+It is all for today,

+
+
+Compiling RRDtool 1.2.x on Win32 with MingW32 gcc:
+---------------------------------------------------------------
+
+1. Obtain and install the current version of the MingW package.
+
+     http://www.mingw.org/download.shtml
+
+   In the MinGW set you will need the gcc and binutils as a minimum.
+
+2. Obtain either of the following awk versions and install in a directory
+   on your System Path:
+
+   - awk.exe
+
+     http://cm.bell-labs.com/cm/cs/awkbook/index.html
+
+     Note: This version has no dependencies to other libs.
+
+   - gawk.exe  (GnuWin32 version)
+
+     http://gnuwin32.sourceforge.net/packages/gawk.htm
+
+     Note: Also fetch the dependant libraries for it from the same page.
+
+3. If you plan to create a 'distribution' release of the RRD Tools, the
+   Makefile.Win32 will copy all the needed files to an output directory and
+   then zip the entire directory. A suitable zip utility can be obtained here:
+
+     http://www.info-zip.org/
+
+   Install in a directory on your System Path.
+
+4. Obtain the following libraries, ideally install them all under a common
+   directory:
+
+   = zlib
+
+     http://oss.oetiker.ch/rrdtool/pub/libs/zlib-1.2.3.tar.gz
+     http://www.zlib.net/
+
+   = libpng
+
+     http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.12.tar.gz
+     http://libpng.sourceforge.net/
+
+   = freetype
+
+     http://oss.oetiker.ch/rrdtool/pub/libs/freetype-2.2.1.tar.gz
+     http://freetype.sourceforge.net/index2.html
+ 
+   = libart_lgpl
+
+     http://oss.oetiker.ch/rrdtool/pub/libs/libart_lgpl-2.3.17.tar.gz
+     http://www.levien.com/libart/
+
+     Note: libart_lgpl needs a special tweak because the archive contains
+     only the base directory, but the libart headers are usually included with
+     a directory prefix; therefore create a subfolder 'libart_lgpl' and move
+     all files into this subfolder.
+
+5. Set up for DOS environment.
+
+   Add MingW\bin and MSYS\bin directories to your System path.
+
+   If the libraries share a common directory set the following environment var:
+
+     set LIBBASE=<shared director>
+     e.g set LIBBASE=C:\Libraries
+
+   If the libraries are scattered, set the following environment vers:
+
+     set ZLIBSDK=<path to zlib>
+     e.g set ZLIBSDK=C:\mytest\zlib-1.2.3
+     set LIBPNG=<path to libpng>
+     set LIBFT2=<path to freetype>
+     set LIBART=<path to libart>
+
+   If using the Gnu Awk (gawk.exe), edit the Makefile.Win32 and change the line:
+
+      AWK      = awk
+
+   to
+
+      AWK      = gawk
+
+6. Compile the project.
+
+   All dependent libs are statically linked in. This has the benefit that the
+   binaries do not depend on any other DLLs.
+   In order to build the static freetype lib enter the freetype base directory
+   and type 'make'. If everything is fine a message appears that gcc is detected,
+   and that you should again type 'make'. Follow that in order to build freetype.
+   All other libs are build from the sources with the RRDTool Makefile.Win32.
+
+   Switch to the RRDTOOL .\src directory. Then:
+
+      make -f Makefile.Win32 help
+
+   to see the build options, or
+
+      make -f Makefile.Win32 all
+
+   should build the entire package.
+
+6. Happy Graphing!

+dnl
+dnl This macro figures out how to build C programs using POSIX threads.
+dnl It sets the PTHREAD_LIBS output variable to the threads library and
+dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
+dnl C compiler flags that are needed. (The user can also force certain
+dnl compiler flags/libs to be tested by setting these environment
+dnl variables.)
+dnl
+dnl Also sets PTHREAD_CC to any special C compiler that is needed for
+dnl multi-threaded programs (defaults to the value of CC otherwise).
+dnl (This is necessary on AIX to use the special cc_r compiler alias.)
+dnl
+dnl NOTE: You are assumed to not only compile your program with these
+dnl flags, but also link it with them as well. e.g. you should link
+dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
+dnl $LIBS
+dnl
+dnl If you are only building threads programs, you may wish to use
+dnl these variables in your default LIBS, CFLAGS, and CC:
+dnl
+dnl        LIBS="$PTHREAD_LIBS $LIBS"
+dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+dnl        CC="$PTHREAD_CC"
+dnl
+dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
+dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
+dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+dnl
+dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
+dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
+dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
+dnl default action will define HAVE_PTHREAD.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+package RRDp;
+
+=head1 NAME
+
+RRDp - Attach RRDtool from within a perl script via a set of pipes;
+
+=head1 SYNOPSIS
+
+use B<RRDp>
+
+B<RRDp::start> I<path to RRDtool executable>
+
+B<RRDp::cmd>  I<rrdtool commandline>
+
+$answer = B<RRD::read>
+
+$status = B<RRD::end>
+
+B<$RRDp::user>,  B<$RRDp::sys>, B<$RRDp::real>, B<$RRDp::error_mode>, B<$RRDp::error>
+
+=head1 DESCRIPTION
+
+With this module you can safely communicate with the RRDtool. 
+
+After every B<RRDp::cmd> you have to issue an B<RRDp::read> command to get
+B<RRDtool>s answer to your command. The answer is returned as a pointer,
+in order to speed things up. If the last command did not return any
+data, B<RRDp::read> will return an undefined variable. 
+
+If you import the PERFORMANCE variables into your namespace, 
+you can access RRDtool's internal performance measurements.
+
+=over 8
+
+=item  use B<RRDp>
+
+Load the RRDp::pipe module.
+
+=item B<RRDp::start> I<path to RRDtool executable>
+
+start RRDtool. The argument must be the path to the RRDtool executable
+
+=item B<RRDp::cmd> I<rrdtool commandline>
+
+pass commands on to RRDtool. check the RRDtool documentation for
+more info on the RRDtool commands.
+
+=item $answer = B<RRDp::read>
+
+read RRDtool's response to your command. Note that the $answer variable will
+only contain a pointer to the returned data. The reason for this is, that
+RRDtool can potentially return quite excessive amounts of data
+and we don't want to copy this around in memory. So when you want to 
+access the contents of $answer you have to use $$answer which dereferences
+the variable.
+
+=item $status = B<RRDp::end>
+
+terminates RRDtool and returns RRDtool's status ... 
+
+=item B<$RRDp::user>,  B<$RRDp::sys>, B<$RRDp::real>
+
+these variables will contain totals of the user time, system time and
+real time as seen by RRDtool.  User time is the time RRDtool is
+running, System time is the time spend in system calls and real time
+is the total time RRDtool has been running.
+
+The difference between user + system and real is the time spent
+waiting for things like the hard disk and new input from the perl
+script.
+
+=item B<$RRDp::error_mode> and B<$RRDp::error>
+
+If you set the variable $RRDp::error_mode to the value 'catch' before you run RRDp::read a potential
+ERROR message will not cause the program to abort but will be returned in this variable. If no error
+occurs the variable will be empty.
+
+ $RRDp::error_mode = 'catch';
+ RRDp::cmd qw(info file.rrd);
+ print $RRDp::error if $RRDp::error;
+

+=head1 NAME
+
+RRDs - Access RRDtool as a shared module
+
+=head1 SYNOPSIS
+
+  use RRDs;
+  RRDs::error
+  RRDs::last ...
+  RRDs::info ...
+  RRDs::create ...
+  RRDs::update ...
+  RRDs::updatev ...
+  RRDs::graph ...
+  RRDs::fetch ...
+  RRDs::tune ...
+  RRDs::times(start, end)
+  RRDs::dump ...
+  RRDs::restore ...
+
+=head1 DESCRIPTION
+
+=head2 Calling Sequence
+
+This module accesses RRDtool functionality directly from within perl. The
+arguments to the functions listed in the SYNOPSIS are explained in the regular
+RRDtool documentation. The commandline call
+
+ rrdtool update mydemo.rrd --template in:out N:12:13
+
+gets turned into
+
+ RRDs::update ("mydemo.rrd", "--template", "in:out", "N:12:13");
+
+Note that
+
+ --template=in:out
+
+is also valid.
+
+The RRDs::times function takes two parameters:  a "start" and "end" time.
+These should be specified in the B<AT-STYLE TIME SPECIFICATION> format
+used by RRDtool.  See the B<rrdfetch> documentation for a detailed
+explanation on how to specify time.
+
+=head2 Error Handling
+
+The RRD functions will not abort your program even when they can not make
+sense out of the arguments you fed them.
+
+The function RRDs::error should be called to get the error status
+after each function call. If RRDs::error does not return anything
+then the previous function has completed its task successfully.
+
+ use RRDs;
+ RRDs::update ("mydemo.rrd","N:12:13");
+ my $ERR=RRDs::error;
+ die "ERROR while updating mydemo.rrd: $ERR\n" if $ERR;
+
+=head2 Return Values
+
+The functions RRDs::last, RRDs::graph, RRDs::info, RRDs::fetch and RRDs::times
+return their findings.
+
+B<RRDs::last> returns a single INTEGER representing the last update time.
+
+ $lastupdate = RRDs::last ...
+
+B<RRDs::graph> returns an pointer to an ARRAY containing the x-size and y-size of the
+created image and results of the PRINT arguments.
+
+ ($averages,$xsize,$ysize) = RRDs::graph ...
+ print "Imagesize: ${xsize}x${ysize}\n";
+ print "Averages: ", (join ", ", @$averages);
+
+B<RRDs::info> returns a pointer to a hash. The keys of the hash
+represent the property names of the RRD and the values of the hash are
+the values of the properties.  
+
+ $hash = RRDs::info "example.rrd";
+ foreach my $key (keys %$hash){
+   print "$key = $$hash{$key}\n";
+ }
+
+B<RRDs::updatev> also returns a pointer to hash. The keys of the hash
+are concatenated strings of a timestamp, RRA index, and data source name for
+each consolidated data point (CDP) written to disk as a result of the
+current update call. The hash values are CDP values.
+
+B<RRDs::fetch> is the most complex of
+the pack regarding return values. There are 4 values. Two normal
+integers, a pointer to an array and a pointer to a array of pointers.
+
+  my ($start,$step,$names,$data) = RRDs::fetch ... 
+  print "Start:       ", scalar localtime($start), " ($start)\n";
+  print "Step size:   $step seconds\n";
+  print "DS names:    ", join (", ", @$names)."\n";
+  print "Data points: ", $#$data + 1, "\n";
+  print "Data:\n";
+  foreach my $line (@$data) {
+    print "  ", scalar localtime($start), " ($start) ";
+    $start += $step;
+    foreach my $val (@$line) {
+      printf "%12.1f ", $val;
+    }
+    print "\n";
+  }
+
+B<RRDs::times> returns two integers which are the number of seconds since
+epoch (1970-01-01) for the supplied "start" and "end" arguments, respectively.
+
+See the examples directory for more ways to use this extension.
+
+=head1 NOTE
+
+If you are manipulating the TZ variable you should also call the posixs
+function tzset to initialize all internal state of the library for properly
+operating in the timezone of your choice.
+
+ use POSIX qw(tzset);
+ $ENV{TZ} = 'CET';   
+ POSIX::tzset();

+                 GNU LESSER GENERAL PUBLIC LICENSE
+                      Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+\f
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+\f
+                 GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+\f
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+\f
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+\f
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+\f
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+\f
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+\f
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                           NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                    END OF TERMS AND CONDITIONS
+\f
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+# ruby librrd bindings
+# author: Miles Egan <miles@caddr.com>
+#
+
+- Introduction 
+
+This module provides ruby bindings for librrd, with functionality
+comparable to the native perl bindings.  See test.rb for a script that
+exercises all ruby-librrd functionality.
+
+- Installation
+
+Installation is standard.  Simply run:
+
+ruby extconf.rb
+make
+make install
+
+I hope this works for you.  Please let me know if you have any
+problems or suggestions.  Someday when I'm feeling less lazy I'll
+actually document this thing.  Thanks to Tobi for rrdtool!

+TCLRRD -- A TCL interpreter extension to access the RRD library,
+         contributed to Tobias Oetiker's RRD tools.
+
+Copyright (c) 1999,2000 Frank Strauss, Technical University of Braunschweig.
+
+See the file "COPYING" for information on usage and redistribution
+of this file, and for a DISCLAIMER OF ALL WARRANTIES.
+
+TCLRRD adds a dynamically loadable package to the Tcl 8.x interpreter
+to access all RRD functions as of RRDtool 1.0.13. All command names
+and arguments are equal to those of RRDtool. They are assigned to the
+namespace `Rrd', e.g.  `Rrd::create'. Return values are a bit
+different from plain RRDtool behavior to enable more native Tcl
+usage. Errors are mapped to the TCL_ERROR return code together with
+the RRD error strings.
+
+TCLRRD makes it easy to combine RRD use with advanced SNMP functionality
+of scotty (http://wwwsnmp.cs.utwente.nl/~schoenw/scotty/). E.g., it's easy
+to use some scotty code to get the counters of some interfaces by their
+interface name and then use Rrd::update to store the values. Furthermore,
+data source types (see RRD::create documentation) and integer value ranges
+could be easily retrieved from MIB information.
+
+TCLRRD has been written on a Linux system for use with Tcl 8.x. It should
+work on many other platforms, although it has not been tested. There are
+no fool proof installation procedures. Take a look at Makefile.am and
+adapt it, if required.
+
+TCLRRD has been written for RRD 1.0.13.

+\`configure' configures rrdtool 1.2.26 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                         [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+   Here is a matrix of mmap possibilities:
+       mmap private not fixed
+       mmap private fixed at somewhere currently unmapped
+       mmap private fixed at somewhere already mapped
+       mmap shared not fixed
+       mmap shared fixed at somewhere currently unmapped
+       mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>With this module you can safely communicate with the RRDtool.</p>
+<p>After every <strong>RRDp::cmd</strong> you have to issue an <strong>RRDp::read</strong> command to get
+<strong>RRDtool</strong>s answer to your command. The answer is returned as a pointer,
+in order to speed things up. If the last command did not return any
+data, <strong>RRDp::read</strong> will return an undefined variable.</p>
+<p>If you import the PERFORMANCE variables into your namespace, 
+you can access RRDtool's internal performance measurements.</p>
+<dl>

+
+<dd>
+<p>start RRDtool. The argument must be the path to the RRDtool executable</p>
+</dd>

+more info on the RRDtool commands.</p>
+</dd>
+</li>
+<dt><strong><a name="item__answer">$answer = <strong>RRDp::read</strong></a></strong>
+
+<dd>
+<p>read RRDtool's response to your command. Note that the $answer variable will
+only contain a pointer to the returned data. The reason for this is, that
+RRDtool can potentially return quite excessive amounts of data
+and we don't want to copy this around in memory. So when you want to 
+access the contents of $answer you have to use $$answer which dereferences
+the variable.</p>
+</dd>
+</li>
+<dt><strong><a name="item__status">$status = <strong>RRDp::end</strong></a></strong>

+
+<dd>
+<p>these variables will contain totals of the user time, system time and
+real time as seen by RRDtool.  User time is the time RRDtool is
+running, System time is the time spend in system calls and real time
+is the total time RRDtool has been running.</p>
+</dd>
+<dd>
+<p>The difference between user + system and real is the time spent
+waiting for things like the hard disk and new input from the perl
+script.</p>

+<p>If you set the variable $RRDp::error_mode to the value 'catch' before you run RRDp::read a potential
+ERROR message will not cause the program to abort but will be returned in this variable. If no error
+occurs the variable will be empty.</p>

+<h2><a name="calling_sequence">Calling Sequence</a></h2>
+<p>This module accesses RRDtool functionality directly from within perl. The
+arguments to the functions listed in the SYNOPSIS are explained in the regular
+RRDtool documentation. The commandline call</p>
+<pre>
+ rrdtool update mydemo.rrd --template in:out N:12:13</pre>
+<p>gets turned into</p>
+<pre>
+ RRDs::update (&quot;mydemo.rrd&quot;, &quot;--template&quot;, &quot;in:out&quot;, &quot;N:12:13&quot;);</pre>
+<p>Note that</p>
+<pre>
+ --template=in:out</pre>
+<p>is also valid.</p>
+<p>The RRDs::times function takes two parameters:  a ``start'' and ``end'' time.
+These should be specified in the <strong>AT-STYLE TIME SPECIFICATION</strong> format
+used by RRDtool.  See the <strong>rrdfetch</strong> documentation for a detailed
+explanation on how to specify time.</p>
+<p>
+</p>
+<h2><a name="error_handling">Error Handling</a></h2>
+<p>The RRD functions will not abort your program even when they can not make
+sense out of the arguments you fed them.</p>
+<p>The function RRDs::error should be called to get the error status
+after each function call. If RRDs::error does not return anything
+then the previous function has completed its task successfully.</p>
+<pre>
+ use RRDs;
+ RRDs::update (&quot;mydemo.rrd&quot;,&quot;N:12:13&quot;);
+ my $ERR=RRDs::error;
+ die &quot;ERROR while updating mydemo.rrd: $ERR\n&quot; if $ERR;</pre>
+<p>
+</p>
+<h2><a name="return_values">Return Values</a></h2>
+<p>The functions RRDs::last, RRDs::graph, RRDs::info, RRDs::fetch and RRDs::times
+return their findings.</p>
+<p><strong>RRDs::last</strong> returns a single INTEGER representing the last update time.</p>
+<pre>
+ $lastupdate = RRDs::last ...</pre>
+<p><strong>RRDs::graph</strong> returns an pointer to an ARRAY containing the x-size and y-size of the
+created image and results of the PRINT arguments.</p>
+<pre>
+ ($averages,$xsize,$ysize) = RRDs::graph ...
+ print &quot;Imagesize: ${xsize}x${ysize}\n&quot;;
+ print &quot;Averages: &quot;, (join &quot;, &quot;, @$averages);</pre>
+<p><strong>RRDs::info</strong> returns a pointer to a hash. The keys of the hash
+represent the property names of the RRD and the values of the hash are
+the values of the properties.</p>
+<pre>
+ $hash = RRDs::info &quot;example.rrd&quot;;
+ foreach my $key (keys %$hash){
+   print &quot;$key = $$hash{$key}\n&quot;;
+ }</pre>
+<p><strong>RRDs::updatev</strong> also returns a pointer to hash. The keys of the hash
+are concatenated strings of a timestamp, RRA index, and data source name for
+each consolidated data point (CDP) written to disk as a result of the
+current update call. The hash values are CDP values.</p>
+<p><strong>RRDs::fetch</strong> is the most complex of
+the pack regarding return values. There are 4 values. Two normal
+integers, a pointer to an array and a pointer to a array of pointers.</p>
+<pre>
+  my ($start,$step,$names,$data) = RRDs::fetch ... 
+  print &quot;Start:       &quot;, scalar localtime($start), &quot; ($start)\n&quot;;
+  print &quot;Step size:   $step seconds\n&quot;;
+  print &quot;DS names:    &quot;, join (&quot;, &quot;, @$names).&quot;\n&quot;;
+  print &quot;Data points: &quot;, $#$data + 1, &quot;\n&quot;;
+  print &quot;Data:\n&quot;;
+  foreach my $line (@$data) {
+    print &quot;  &quot;, scalar localtime($start), &quot; ($start) &quot;;
+    $start += $step;
+    foreach my $val (@$line) {
+      printf &quot;%12.1f &quot;, $val;
+    }
+    print &quot;\n&quot;;
+  }</pre>
+<p><strong>RRDs::times</strong> returns two integers which are the number of seconds since
+epoch (1970-01-01) for the supplied ``start'' and ``end'' arguments, respectively.</p>

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+Most people use the decimal numbering system. This system uses ten
+symbols to represent numbers. When those ten symbols are used up, they
+start all over again and increment the position to the left. The
+digit 0 is only shown if it is the only symbol in the sequence, or if
+it is not the first one.
+.PP
+If this sounds cryptic to you, this is what I've just said in numbers:
+.PP
+.Vb 14
+\&     0
+\&     1
+\&     2
+\&     3
+\&     4
+\&     5
+\&     6
+\&     7
+\&     8
+\&     9
+\&    10
+\&    11
+\&    12
+\&    13
+.Ve
+.PP
+and so on.
+.PP
+Each time the digit nine is incremented, it is reset to 0 and the
+position before (to the left) is incremented (from 0 to 1). Then
+number 9 can be seen as \*(L"00009\*(R" and when we should increment 9, we
+reset it to zero and increment the digit just before the 9 so the
+number becomes \*(L"00010\*(R". Leading zeros we don't write except if it is
+the only digit (number 0). And of course, we write zeros if they occur
+anywhere inside or at the end of a number:
+.PP
+.Vb 1
+\& "00010" \-> " 0010" \-> " 010" \-> "  10", but not "  1 ".
+.Ve
+.PP
+This was pretty basic, you already knew this. Why did I tell it?
+Well, computers usually do not represent numbers with 10 different
+digits. They only use two different symbols, namely \*(L"0\*(R" and \*(L"1\*(R". Apply
+the same rules to this set of digits and you get the binary numbering
+system:
+.PP
+.Vb 14
+\&     0
+\&     1
+\&    10
+\&    11
+\&   100
+\&   101
+\&   110
+\&   111
+\&  1000
+\&  1001
+\&  1010
+\&  1011
+\&  1100
+\&  1101
+.Ve
+.PP
+and so on.
+.PP
+If you count the number of rows, you'll see that these are again 14
+different numbers. The numbers are the same and mean the same as in
+the first list, we just used a different representation. This means
+that you have to know the representation used, or as it is called the
+numbering system or base.  Normally, if we do not explicitly specify
+the numbering system used, we implicitly use the decimal system. If we
+want to use any other numbering system, we'll have to make that
+clear. There are a few widely adopted methods to do so. One common
+form is to write 1010(2) which means that you wrote down a number in
+its binary representation. It is the number ten. If you would write
+1010 without specifying the base, the number is interpreted as one
+thousand and ten using base 10.
+.PP
+In books, another form is common. It uses subscripts (little
+characters, more or less in between two rows). You can leave out the
+parentheses in that case and write down the number in normal
+characters followed by a little two just behind it.
+.PP
+As the numbering system used is also called the base, we talk of the
+number 1100 base 2, the number 12 base 10.
+.PP
+Within the binary system, it is common to write leading zeros. The
+numbers are written down in series of four, eight or sixteen depending
+on the context.
+.PP
+We can use the binary form when talking to computers
+(...programming...), but the numbers will have large
+representations. The number 65'535 (often in the decimal system a ' is
+used to separate blocks of three digits for readability) would be
+written down as 1111111111111111(2) which is 16 times the digit 1.
+This is difficult and prone to errors. Therefore, we usually would use
+another base, called hexadecimal. It uses 16 different symbols. First
+the symbols from the decimal system are used, thereafter we continue
+with alphabetic characters. We get 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
+A, B, C, D, E and F. This system is chosen because the hexadecimal
+form can be converted into the binary system very easily (and back).
+.PP
+There is yet another system in use, called the octal system. This was
+more common in the old days, but is not used very often anymore. As
+you might find it in use sometimes, you should get used to it and
+we'll show it below. It's the same story as with the other
+representations, but with eight different symbols.
+.PP
+.Vb 4
+\& Binary      (2)

+.Ve
+.PP
+Most computers used nowadays are using bytes of eight bits. This means
+that they store eight bits at a time. You can see why the octal system
+is not the most practical for that: You'd need three digits to represent
+the eight bits and this means that you'd have to use one complete digit
+to represent only two bits (2+3+3=8). This is a waste. For hexadecimal
+digits, you need only two digits which are used completely:
+.PP
+.Vb 2
+\& (2)      (8)  (10) (16)
+\& 11111111 377  255   FF
+.Ve
+.PP
+You can see why binary and hexadecimal can be converted quickly: For
+each hexadecimal digit there are exactly four binary digits.  Take a
+binary number: take four digits from the right and make a hexadecimal
+digit from it (see the table above). Repeat this until there are no
+more digits. And the other way around: Take a hexadecimal number. For
+each digit, write down its binary equivalent.
+.PP
+Computers (or rather the parsers running on them) would have a hard
+time converting a number like 1234(16). Therefore hexadecimal numbers
+are specified with a prefix. This prefix depends on the language
+you're writing in. Some of the prefixes are \*(L"0x\*(R" for C, \*(L"$\*(R" for
+Pascal, \*(L"#\*(R" for \s-1HTML\s0.  It is common to assume that if a number starts
+with a zero, it is octal. It does not matter what is used as long as
+you know what it is. I will use \*(L"0x\*(R" for hexadecimal, \*(L"%\*(R" for binary
+and \*(L"0\*(R" for octal.  The following numbers are all the same, just their represenatation (base) is different: 021 0x11 17 \f(CW%00010001\fR
+.PP
+To do arithmetics and conversions you need to understand one more thing.
+It is something you already know but perhaps you do not \*(L"see\*(R" it yet:
+.PP
+If you write down 1234, (no prefix, so it is decimal) you are talking
+about the number one thousand, two hundred and thirty four. In sort of
+a formula:
+.PP
+.Vb 4
+\& 1 * 1000 = 1000
+\& 2 *  100 =  200
+\& 3 *   10 =   30
+\& 4 *    1 =    4
+.Ve
+.PP
+This can also be written as:
+.PP
+.Vb 4
+\& 1 * 10^3
+\& 2 * 10^2
+\& 3 * 10^1
+\& 4 * 10^0
+.Ve
+.PP
+where ^ means \*(L"to the power of\*(R".
+.PP
+We are using the base 10, and the positions 0,1,2 and 3.
+The right-most position should \s-1NOT\s0 be multiplied with 10. The second
+from the right should be multiplied one time with 10. The third from
+the right is multiplied with 10 two times. This continues for whatever
+positions are used.
+.PP
+It is the same in all other representations:
+.PP
+0x1234 will be
+.PP
+.Vb 4
+\& 1 * 16^3
+\& 2 * 16^2
+\& 3 * 16^1
+\& 4 * 16^0
+.Ve
+.PP
+01234 would be
+.PP
+.Vb 4
+\& 1 * 8^3
+\& 2 * 8^2
+\& 3 * 8^1
+\& 4 * 8^0
+.Ve
+.PP
+This example can not be done for binary as that system only uses two
+symbols. Another example:
+.PP
+%1010 would be
+.PP
+.Vb 4
+\& 1 * 2^3
+\& 0 * 2^2
+\& 1 * 2^1
+\& 0 * 2^0
+.Ve
+.PP
+It would have been easier to convert it to its hexadecimal form and
+just translate \f(CW%1010\fR into 0xA. After a while you get used to it. You will
+not need to do any calculations anymore, but just know that 0xA means 10.
+.PP
+To convert a decimal number into a hexadecimal you could use the next
+method. It will take some time to be able to do the estimates, but it
+will be easier when you use the system more frequently. We'll look at
+yet another way afterwards.
+.PP
+First you need to know how many positions will be used in the other
+system. To do so, you need to know the maximum numbers you'll be
+using. Well, that's not as hard as it looks. In decimal, the maximum
+number that you can form with two digits is \*(L"99\*(R". The maximum for
+three: \*(L"999\*(R". The next number would need an extra position. Reverse
+this idea and you will see that the number can be found by taking 10^3
+(10*10*10 is 1000) minus 1 or 10^2 minus one.
+.PP
+This can be done for hexadecimal as well:
+.PP
+.Vb 4
+\& 16^4 = 0x10000 = 65536
+\& 16^3 =  0x1000 =  4096
+\& 16^2 =   0x100 =   256
+\& 16^1 =    0x10 =    16
+.Ve
+.PP
+If a number is smaller than 65'536 it will fit in four positions.
+If the number is bigger than 4'095, you must use position 4.
+How many times you can subtract 4'096 from the number without going below
+zero is the first digit you write down. This will always be a number
+from 1 to 15 (0x1 to 0xF). Do the same for the other positions.
+.PP
+Let's try with 41'029. It is smaller than 16^4 but bigger than 16^3\-1. This
+means that we have to use four positions.
+We can subtract 16^3 from 41'029 ten times without going below zero.
+The left-most digit will therefore be \*(L"A\*(R", so we have 0xA????.
+The number is reduced to 41'029 \- 10*4'096 = 41'029\-40'960 = 69.
+69 is smaller than 16^3 but not bigger than 16^2\-1. The second digit
+is therefore \*(L"0\*(R" and we now have 0xA0??.
+69 is smaller than 16^2 and bigger than 16^1\-1. We can subtract 16^1
+(which is just plain 16) four times and write down \*(L"4\*(R" to get 0xA04?.
+Subtract 64 from 69 (69 \- 4*16) and the last digit is 5 \-\-> 0xA045.
+.PP
+The other method builds ub the number from the right. Let's try 41'029
+again.  Divide by 16 and do not use fractions (only whole numbers).
+.PP
+.Vb 4
+\& 41'029 / 16 is 2'564 with a remainder of 5. Write down 5.
+\& 2'564 / 16 is 160 with a remainder of 4. Write the 4 before the 5.
+\& 160 / 16 is 10 with no remainder. Prepend 45 with 0.
+\& 10 / 16 is below one. End here and prepend 0xA. End up with 0xA045.

+.PP
+Which method to use is up to you. Use whatever works for you.  I use
+them both without being able to tell what method I use in each case,
+it just depends on the number, I think. Fact is, some numbers will
+occur frequently while programming. If the number is close to one I am
+familiar with, then I will use the first method (like 32'770 which is
+into 32'768 + 2 and I just know that it is 0x8000 + 0x2 = 0x8002).
+.PP
+For binary the same approach can be used. The base is 2 and not 16,
+and the number of positions will grow rapidly. Using the second method
+has the advantage that you can see very easily if you should write down
+a zero or a one: if you divide by two the remainder will be zero if it
+is an even number and one if it is an odd number:

+For low values, try to do the calculations yourself, then check them with

+When the numbers get bigger, you'll have to realize that a computer is

+Start the calculator (start\->programs\->accessories\->calculator)

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>Most people use the decimal numbering system. This system uses ten
+symbols to represent numbers. When those ten symbols are used up, they
+start all over again and increment the position to the left. The
+digit 0 is only shown if it is the only symbol in the sequence, or if
+it is not the first one.</p>
+<p>If this sounds cryptic to you, this is what I've just said in numbers:</p>
+<pre>
+     0
+     1
+     2
+     3
+     4
+     5
+     6
+     7
+     8
+     9
+    10
+    11
+    12
+    13</pre>
+<p>and so on.</p>
+<p>Each time the digit nine is incremented, it is reset to 0 and the
+position before (to the left) is incremented (from 0 to 1). Then
+number 9 can be seen as ``00009'' and when we should increment 9, we
+reset it to zero and increment the digit just before the 9 so the
+number becomes ``00010''. Leading zeros we don't write except if it is
+the only digit (number 0). And of course, we write zeros if they occur
+anywhere inside or at the end of a number:</p>
+<pre>
+ &quot;00010&quot; -&gt; &quot; 0010&quot; -&gt; &quot; 010&quot; -&gt; &quot;  10&quot;, but not &quot;  1 &quot;.</pre>
+<p>This was pretty basic, you already knew this. Why did I tell it?
+Well, computers usually do not represent numbers with 10 different
+digits. They only use two different symbols, namely ``0'' and ``1''. Apply
+the same rules to this set of digits and you get the binary numbering
+system:</p>
+<pre>
+     0
+     1
+    10
+    11
+   100
+   101
+   110
+   111
+  1000
+  1001
+  1010
+  1011
+  1100
+  1101</pre>
+<p>and so on.</p>
+<p>If you count the number of rows, you'll see that these are again 14
+different numbers. The numbers are the same and mean the same as in
+the first list, we just used a different representation. This means
+that you have to know the representation used, or as it is called the
+numbering system or base.  Normally, if we do not explicitly specify
+the numbering system used, we implicitly use the decimal system. If we
+want to use any other numbering system, we'll have to make that
+clear. There are a few widely adopted methods to do so. One common
+form is to write <code>1010(2)</code> which means that you wrote down a number in
+its binary representation. It is the number ten. If you would write
+1010 without specifying the base, the number is interpreted as one
+thousand and ten using base 10.</p>
+<p>In books, another form is common. It uses subscripts (little
+characters, more or less in between two rows). You can leave out the
+parentheses in that case and write down the number in normal
+characters followed by a little two just behind it.</p>
+<p>As the numbering system used is also called the base, we talk of the
+number 1100 base 2, the number 12 base 10.</p>
+<p>Within the binary system, it is common to write leading zeros. The
+numbers are written down in series of four, eight or sixteen depending
+on the context.</p>
+<p>We can use the binary form when talking to computers
+(...programming...), but the numbers will have large
+representations. The number 65'535 (often in the decimal system a ' is
+used to separate blocks of three digits for readability) would be
+written down as <code>1111111111111111(2)</code> which is 16 times the digit 1.
+This is difficult and prone to errors. Therefore, we usually would use
+another base, called hexadecimal. It uses 16 different symbols. First
+the symbols from the decimal system are used, thereafter we continue
+with alphabetic characters. We get 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
+A, B, C, D, E and F. This system is chosen because the hexadecimal
+form can be converted into the binary system very easily (and back).</p>
+<p>There is yet another system in use, called the octal system. This was
+more common in the old days, but is not used very often anymore. As
+you might find it in use sometimes, you should get used to it and
+we'll show it below. It's the same story as with the other
+representations, but with eight different symbols.</p>
+<pre>
+ Binary      (2)
+ Octal       (8)
+ Decimal     (10)
+ Hexadecimal (16)</pre>

+<p>Most computers used nowadays are using bytes of eight bits. This means
+that they store eight bits at a time. You can see why the octal system
+is not the most practical for that: You'd need three digits to represent
+the eight bits and this means that you'd have to use one complete digit
+to represent only two bits (2+3+3=8). This is a waste. For hexadecimal
+digits, you need only two digits which are used completely:</p>
+<pre>
+ (2)      (8)  (10) (16)
+ 11111111 377  255   FF</pre>
+<p>You can see why binary and hexadecimal can be converted quickly: For
+each hexadecimal digit there are exactly four binary digits.  Take a
+binary number: take four digits from the right and make a hexadecimal
+digit from it (see the table above). Repeat this until there are no
+more digits. And the other way around: Take a hexadecimal number. For
+each digit, write down its binary equivalent.</p>
+<p>Computers (or rather the parsers running on them) would have a hard
+time converting a number like 1234(16). Therefore hexadecimal numbers
+are specified with a prefix. This prefix depends on the language
+you're writing in. Some of the prefixes are ``0x'' for C, ``$'' for
+Pascal, ``#'' for HTML.  It is common to assume that if a number starts
+with a zero, it is octal. It does not matter what is used as long as
+you know what it is. I will use ``0x'' for hexadecimal, ``%'' for binary
+and ``0'' for octal.  The following numbers are all the same, just their represenatation (base) is different: 021 0x11 17 %00010001</p>
+<p>To do arithmetics and conversions you need to understand one more thing.
+It is something you already know but perhaps you do not ``see'' it yet:</p>
+<p>If you write down 1234, (no prefix, so it is decimal) you are talking
+about the number one thousand, two hundred and thirty four. In sort of
+a formula:</p>
+<pre>
+ 1 * 1000 = 1000
+ 2 *  100 =  200
+ 3 *   10 =   30
+ 4 *    1 =    4</pre>
+<p>This can also be written as:</p>
+<pre>
+ 1 * 10^3
+ 2 * 10^2
+ 3 * 10^1
+ 4 * 10^0</pre>
+<p>where ^ means ``to the power of''.</p>
+<p>We are using the base 10, and the positions 0,1,2 and 3.
+The right-most position should NOT be multiplied with 10. The second
+from the right should be multiplied one time with 10. The third from
+the right is multiplied with 10 two times. This continues for whatever
+positions are used.</p>
+<p>It is the same in all other representations:</p>
+<p>0x1234 will be</p>
+<pre>
+ 1 * 16^3
+ 2 * 16^2
+ 3 * 16^1
+ 4 * 16^0</pre>
+<p>01234 would be</p>
+<pre>
+ 1 * 8^3
+ 2 * 8^2
+ 3 * 8^1
+ 4 * 8^0</pre>
+<p>This example can not be done for binary as that system only uses two
+symbols. Another example:</p>
+<p>%1010 would be</p>
+<pre>
+ 1 * 2^3
+ 0 * 2^2
+ 1 * 2^1
+ 0 * 2^0</pre>
+<p>It would have been easier to convert it to its hexadecimal form and
+just translate %1010 into 0xA. After a while you get used to it. You will
+not need to do any calculations anymore, but just know that 0xA means 10.</p>
+<p>To convert a decimal number into a hexadecimal you could use the next
+method. It will take some time to be able to do the estimates, but it
+will be easier when you use the system more frequently. We'll look at
+yet another way afterwards.</p>
+<p>First you need to know how many positions will be used in the other
+system. To do so, you need to know the maximum numbers you'll be
+using. Well, that's not as hard as it looks. In decimal, the maximum
+number that you can form with two digits is ``99''. The maximum for
+three: ``999''. The next number would need an extra position. Reverse
+this idea and you will see that the number can be found by taking 10^3
+(10*10*10 is 1000) minus 1 or 10^2 minus one.</p>
+<p>This can be done for hexadecimal as well:</p>
+<pre>
+ 16^4 = 0x10000 = 65536
+ 16^3 =  0x1000 =  4096
+ 16^2 =   0x100 =   256
+ 16^1 =    0x10 =    16</pre>
+<p>If a number is smaller than 65'536 it will fit in four positions.
+If the number is bigger than 4'095, you must use position 4.
+How many times you can subtract 4'096 from the number without going below
+zero is the first digit you write down. This will always be a number
+from 1 to 15 (0x1 to 0xF). Do the same for the other positions.</p>
+<p>Let's try with 41'029. It is smaller than 16^4 but bigger than 16^3-1. This
+means that we have to use four positions.
+We can subtract 16^3 from 41'029 ten times without going below zero.
+The left-most digit will therefore be ``A'', so we have 0xA????.
+The number is reduced to 41'029 - 10*4'096 = 41'029-40'960 = 69.
+69 is smaller than 16^3 but not bigger than 16^2-1. The second digit
+is therefore ``0'' and we now have 0xA0??.
+69 is smaller than 16^2 and bigger than 16^1-1. We can subtract 16^1
+(which is just plain 16) four times and write down ``4'' to get 0xA04?.
+Subtract 64 from 69 (69 - 4*16) and the last digit is 5 --&gt; 0xA045.</p>
+<p>The other method builds ub the number from the right. Let's try 41'029
+again.  Divide by 16 and do not use fractions (only whole numbers).</p>
+<pre>
+ 41'029 / 16 is 2'564 with a remainder of 5. Write down 5.
+ 2'564 / 16 is 160 with a remainder of 4. Write the 4 before the 5.
+ 160 / 16 is 10 with no remainder. Prepend 45 with 0.
+ 10 / 16 is below one. End here and prepend 0xA. End up with 0xA045.</pre>
+<p>Which method to use is up to you. Use whatever works for you.  I use
+them both without being able to tell what method I use in each case,
+it just depends on the number, I think. Fact is, some numbers will
+occur frequently while programming. If the number is close to one I am
+familiar with, then I will use the first method (like 32'770 which is
+into 32'768 + 2 and I just know that it is 0x8000 + 0x2 = 0x8002).</p>
+<p>For binary the same approach can be used. The base is 2 and not 16,
+and the number of positions will grow rapidly. Using the second method
+has the advantage that you can see very easily if you should write down
+a zero or a one: if you divide by two the remainder will be zero if it
+is an even number and one if it is an odd number:</p>
+<pre>
+ 41029 / 2 = 20514 remainder 1
+ 20514 / 2 = 10257 remainder 0
+ 10257 / 2 =  5128 remainder 1
+  5128 / 2 =  2564 remainder 0
+  2564 / 2 =  1282 remainder 0
+  1282 / 2 =   641 remainder 0
+   641 / 2 =   320 remainder 1
+   320 / 2 =   160 remainder 0
+   160 / 2 =    80 remainder 0
+    80 / 2 =    40 remainder 0
+    40 / 2 =    20 remainder 0
+    20 / 2 =    10 remainder 0
+    10 / 2 =     5 remainder 0
+     5 / 2 =     2 remainder 1
+     2 / 2 =     1 remainder 0
+     1 / 2 below 0 remainder 1</pre>
+<p>Write down the results from right to left: %1010000001000101</p>
+<p>Group by four:</p>
+<pre>
+ %1010000001000101
+ %101000000100 0101
+ %10100000 0100 0101

+bin_dec_hex - How to use binary, decimal, and hexadecimal notation.

+
+=head1 DESCRIPTION
+
+Most people use the decimal numbering system. This system uses ten
+symbols to represent numbers. When those ten symbols are used up, they
+start all over again and increment the position to the left. The
+digit 0 is only shown if it is the only symbol in the sequence, or if
+it is not the first one.
+
+If this sounds cryptic to you, this is what I've just said in numbers:
+
+     0
+     1
+     2
+     3
+     4
+     5
+     6
+     7
+     8
+     9
+    10
+    11
+    12
+    13
+
+and so on.
+
+Each time the digit nine is incremented, it is reset to 0 and the
+position before (to the left) is incremented (from 0 to 1). Then
+number 9 can be seen as "00009" and when we should increment 9, we
+reset it to zero and increment the digit just before the 9 so the
+number becomes "00010". Leading zeros we don't write except if it is
+the only digit (number 0). And of course, we write zeros if they occur
+anywhere inside or at the end of a number:
+
+ "00010" -> " 0010" -> " 010" -> "  10", but not "  1 ".
+
+This was pretty basic, you already knew this. Why did I tell it?
+Well, computers usually do not represent numbers with 10 different
+digits. They only use two different symbols, namely "0" and "1". Apply
+the same rules to this set of digits and you get the binary numbering
+system:
+
+     0
+     1
+    10
+    11
+   100
+   101
+   110
+   111
+  1000
+  1001
+  1010
+  1011
+  1100
+  1101
+
+and so on.
+
+If you count the number of rows, you'll see that these are again 14
+different numbers. The numbers are the same and mean the same as in
+the first list, we just used a different representation. This means
+that you have to know the representation used, or as it is called the
+numbering system or base.  Normally, if we do not explicitly specify
+the numbering system used, we implicitly use the decimal system. If we
+want to use any other numbering system, we'll have to make that
+clear. There are a few widely adopted methods to do so. One common
+form is to write 1010(2) which means that you wrote down a number in
+its binary representation. It is the number ten. If you would write
+1010 without specifying the base, the number is interpreted as one
+thousand and ten using base 10.
+
+In books, another form is common. It uses subscripts (little
+characters, more or less in between two rows). You can leave out the
+parentheses in that case and write down the number in normal
+characters followed by a little two just behind it.
+
+As the numbering system used is also called the base, we talk of the
+number 1100 base 2, the number 12 base 10.
+
+Within the binary system, it is common to write leading zeros. The
+numbers are written down in series of four, eight or sixteen depending
+on the context.
+
+We can use the binary form when talking to computers
+(...programming...), but the numbers will have large
+representations. The number 65'535 (often in the decimal system a ' is
+used to separate blocks of three digits for readability) would be
+written down as 1111111111111111(2) which is 16 times the digit 1.
+This is difficult and prone to errors. Therefore, we usually would use
+another base, called hexadecimal. It uses 16 different symbols. First
+the symbols from the decimal system are used, thereafter we continue
+with alphabetic characters. We get 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
+A, B, C, D, E and F. This system is chosen because the hexadecimal
+form can be converted into the binary system very easily (and back).
+
+There is yet another system in use, called the octal system. This was
+more common in the old days, but is not used very often anymore. As
+you might find it in use sometimes, you should get used to it and
+we'll show it below. It's the same story as with the other
+representations, but with eight different symbols.
+
+ Binary      (2)
+ Octal       (8)
+ Decimal     (10)
+ Hexadecimal (16)
+
+ (2)    (8) (10) (16)
+ 00000   0    0    0
+ 00001   1    1    1
+ 00010   2    2    2
+ 00011   3    3    3
+ 00100   4    4    4
+ 00101   5    5    5
+ 00110   6    6    6
+ 00111   7    7    7
+ 01000  10    8    8
+ 01001  11    9    9
+ 01010  12   10    A
+ 01011  13   11    B
+ 01100  14   12    C
+ 01101  15   13    D
+ 01110  16   14    E
+ 01111  17   15    F
+ 10000  20   16   10
+ 10001  21   17   11
+ 10010  22   18   12
+ 10011  23   19   13
+ 10100  24   20   14
+ 10101  25   21   15
+
+Most computers used nowadays are using bytes of eight bits. This means
+that they store eight bits at a time. You can see why the octal system
+is not the most practical for that: You'd need three digits to represent
+the eight bits and this means that you'd have to use one complete digit
+to represent only two bits (2+3+3=8). This is a waste. For hexadecimal
+digits, you need only two digits which are used completely:
+
+ (2)      (8)  (10) (16)
+ 11111111 377  255   FF
+
+You can see why binary and hexadecimal can be converted quickly: For
+each hexadecimal digit there are exactly four binary digits.  Take a
+binary number: take four digits from the right and make a hexadecimal
+digit from it (see the table above). Repeat this until there are no
+more digits. And the other way around: Take a hexadecimal number. For
+each digit, write down its binary equivalent.
+
+Computers (or rather the parsers running on them) would have a hard
+time converting a number like 1234(16). Therefore hexadecimal numbers
+are specified with a prefix. This prefix depends on the language
+you're writing in. Some of the prefixes are "0x" for C, "$" for
+Pascal, "#" for HTML.  It is common to assume that if a number starts
+with a zero, it is octal. It does not matter what is used as long as
+you know what it is. I will use "0x" for hexadecimal, "%" for binary
+and "0" for octal.  The following numbers are all the same, just their represenatation (base) is different: 021 0x11 17 %00010001
+
+To do arithmetics and conversions you need to understand one more thing.
+It is something you already know but perhaps you do not "see" it yet:
+
+If you write down 1234, (no prefix, so it is decimal) you are talking
+about the number one thousand, two hundred and thirty four. In sort of
+a formula:
+
+ 1 * 1000 = 1000
+ 2 *  100 =  200
+ 3 *   10 =   30
+ 4 *    1 =    4
+
+This can also be written as:
+
+ 1 * 10^3
+ 2 * 10^2
+ 3 * 10^1
+ 4 * 10^0
+
+where ^ means "to the power of".
+
+We are using the base 10, and the positions 0,1,2 and 3.
+The right-most position should NOT be multiplied with 10. The second
+from the right should be multiplied one time with 10. The third from
+the right is multiplied with 10 two times. This continues for whatever
+positions are used.
+
+It is the same in all other representations:
+
+0x1234 will be
+
+ 1 * 16^3
+ 2 * 16^2
+ 3 * 16^1
+ 4 * 16^0
+
+01234 would be
+
+ 1 * 8^3
+ 2 * 8^2
+ 3 * 8^1
+ 4 * 8^0
+
+This example can not be done for binary as that system only uses two
+symbols. Another example:
+
+%1010 would be
+
+ 1 * 2^3
+ 0 * 2^2
+ 1 * 2^1
+ 0 * 2^0
+
+It would have been easier to convert it to its hexadecimal form and
+just translate %1010 into 0xA. After a while you get used to it. You will
+not need to do any calculations anymore, but just know that 0xA means 10.
+
+To convert a decimal number into a hexadecimal you could use the next
+method. It will take some time to be able to do the estimates, but it
+will be easier when you use the system more frequently. We'll look at
+yet another way afterwards.
+
+First you need to know how many positions will be used in the other
+system. To do so, you need to know the maximum numbers you'll be
+using. Well, that's not as hard as it looks. In decimal, the maximum
+number that you can form with two digits is "99". The maximum for
+three: "999". The next number would need an extra position. Reverse
+this idea and you will see that the number can be found by taking 10^3
+(10*10*10 is 1000) minus 1 or 10^2 minus one.
+
+This can be done for hexadecimal as well:
+
+ 16^4 = 0x10000 = 65536
+ 16^3 =  0x1000 =  4096
+ 16^2 =   0x100 =   256
+ 16^1 =    0x10 =    16
+
+If a number is smaller than 65'536 it will fit in four positions.
+If the number is bigger than 4'095, you must use position 4.
+How many times you can subtract 4'096 from the number without going below
+zero is the first digit you write down. This will always be a number
+from 1 to 15 (0x1 to 0xF). Do the same for the other positions.
+
+Let's try with 41'029. It is smaller than 16^4 but bigger than 16^3-1. This
+means that we have to use four positions.
+We can subtract 16^3 from 41'029 ten times without going below zero.
+The left-most digit will therefore be "A", so we have 0xA????.
+The number is reduced to 41'029 - 10*4'096 = 41'029-40'960 = 69.
+69 is smaller than 16^3 but not bigger than 16^2-1. The second digit
+is therefore "0" and we now have 0xA0??.
+69 is smaller than 16^2 and bigger than 16^1-1. We can subtract 16^1
+(which is just plain 16) four times and write down "4" to get 0xA04?.
+Subtract 64 from 69 (69 - 4*16) and the last digit is 5 --> 0xA045.
+
+The other method builds ub the number from the right. Let's try 41'029
+again.  Divide by 16 and do not use fractions (only whole numbers).
+
+ 41'029 / 16 is 2'564 with a remainder of 5. Write down 5.
+ 2'564 / 16 is 160 with a remainder of 4. Write the 4 before the 5.
+ 160 / 16 is 10 with no remainder. Prepend 45 with 0.
+ 10 / 16 is below one. End here and prepend 0xA. End up with 0xA045.
+
+Which method to use is up to you. Use whatever works for you.  I use
+them both without being able to tell what method I use in each case,
+it just depends on the number, I think. Fact is, some numbers will
+occur frequently while programming. If the number is close to one I am
+familiar with, then I will use the first method (like 32'770 which is
+into 32'768 + 2 and I just know that it is 0x8000 + 0x2 = 0x8002).
+
+For binary the same approach can be used. The base is 2 and not 16,
+and the number of positions will grow rapidly. Using the second method
+has the advantage that you can see very easily if you should write down
+a zero or a one: if you divide by two the remainder will be zero if it
+is an even number and one if it is an odd number:
+
+ 41029 / 2 = 20514 remainder 1
+ 20514 / 2 = 10257 remainder 0
+ 10257 / 2 =  5128 remainder 1
+  5128 / 2 =  2564 remainder 0
+  2564 / 2 =  1282 remainder 0
+  1282 / 2 =   641 remainder 0
+   641 / 2 =   320 remainder 1
+   320 / 2 =   160 remainder 0
+   160 / 2 =    80 remainder 0
+    80 / 2 =    40 remainder 0
+    40 / 2 =    20 remainder 0
+    20 / 2 =    10 remainder 0
+    10 / 2 =     5 remainder 0
+     5 / 2 =     2 remainder 1
+     2 / 2 =     1 remainder 0
+     1 / 2 below 0 remainder 1
+
+Write down the results from right to left: %1010000001000101
+
+Group by four:
+
+ %1010000001000101
+ %101000000100 0101
+ %10100000 0100 0101
+ %1010 0000 0100 0101
+
+Convert into hexadecimal: 0xA045
+
+Group %1010000001000101 by three and convert into octal:
+
+ %1010000001000101
+ %1010000001000 101
+ %1010000001 000 101
+ %1010000 001 000 101
+ %1010 000 001 000 101
+ %1 010 000 001 000 101
+ %001 010 000 001 000 101
+    1   2   0   1   0   5 --> 0120105
+
+ So: %1010000001000101 = 0120105 = 0xA045 = 41029
+ Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029(10)
+ Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029
+

+       first list, we just used a different representation. This means that
+       you have to know the representation used, or as it is called the num-
+       bering system or base.  Normally, if we do not explicitly specify the
+       numbering system used, we implicitly use the decimal system. If we want
+       to use any other numbering system, we'll have to make that clear. There
+       are a few widely adopted methods to do so. One common form is to write
+       1010(2) which means that you wrote down a number in its binary repre-
+       sentation. It is the number ten. If you would write 1010 without speci-
+       fying the base, the number is interpreted as one thousand and ten using
+       base 10.
+
+       In books, another form is common. It uses subscripts (little charac-
+       ters, more or less in between two rows). You can leave out the paren-
+       theses in that case and write down the number in normal characters fol-
+       lowed by a little two just behind it.
+
+       As the numbering system used is also called the base, we talk of the
+       number 1100 base 2, the number 12 base 10.
+
+       Within the binary system, it is common to write leading zeros. The num-
+       bers are written down in series of four, eight or sixteen depending on
+       the context.
+
+       We can use the binary form when talking to computers (...program-
+       ming...), but the numbers will have large representations. The number
+       65'535 (often in the decimal system a ' is used to separate blocks of
+       three digits for readability) would be written down as
+       1111111111111111(2) which is 16 times the digit 1.  This is difficult
+       and prone to errors. Therefore, we usually would use another base,
+       called hexadecimal. It uses 16 different symbols. First the symbols
+       from the decimal system are used, thereafter we continue with alpha-
+       betic characters. We get 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E
+       and F. This system is chosen because the hexadecimal form can be con-
+       verted into the binary system very easily (and back).
+
+       There is yet another system in use, called the octal system. This was
+       more common in the old days, but is not used very often anymore. As you
+       might find it in use sometimes, you should get used to it and we'll
+       show it below. It's the same story as with the other representations,
+       but with eight different symbols.
+
+        Binary      (2)
+        Octal       (8)
+        Decimal     (10)
+        Hexadecimal (16)
+
+        (2)    (8) (10) (16)
+        00000   0    0    0
+        00001   1    1    1
+        00010   2    2    2
+        00011   3    3    3
+        00100   4    4    4
+        00101   5    5    5
+        00110   6    6    6
+        00111   7    7    7
+        01000  10    8    8
+        01001  11    9    9
+        01010  12   10    A
+        01011  13   11    B
+        01100  14   12    C
+        01101  15   13    D
+        01110  16   14    E
+        01111  17   15    F
+        10000  20   16   10
+        10001  21   17   11
+        10010  22   18   12
+        10011  23   19   13
+        10100  24   20   14
+        10101  25   21   15
+
+       Most computers used nowadays are using bytes of eight bits. This means
+       that they store eight bits at a time. You can see why the octal system
+       is not the most practical for that: You'd need three digits to repre-
+       sent the eight bits and this means that you'd have to use one complete
+       digit to represent only two bits (2+3+3=8). This is a waste. For hex-
+       adecimal digits, you need only two digits which are used completely:
+
+        (2)      (8)  (10) (16)
+        11111111 377  255   FF
+
+       You can see why binary and hexadecimal can be converted quickly: For
+       each hexadecimal digit there are exactly four binary digits.  Take a
+       binary number: take four digits from the right and make a hexadecimal
+       digit from it (see the table above). Repeat this until there are no
+       more digits. And the other way around: Take a hexadecimal number. For
+       each digit, write down its binary equivalent.
+
+       Computers (or rather the parsers running on them) would have a hard
+       time converting a number like 1234(16). Therefore hexadecimal numbers
+       are specified with a prefix. This prefix depends on the language you're
+       writing in. Some of the prefixes are "0x" for C, "$" for Pascal, "#"
+       for HTML.  It is common to assume that if a number starts with a zero,
+       it is octal. It does not matter what is used as long as you know what
+       it is. I will use "0x" for hexadecimal, "%" for binary and "0" for
+       octal.  The following numbers are all the same, just their represenata-
+       tion (base) is different: 021 0x11 17 %00010001
+
+       To do arithmetics and conversions you need to understand one more
+       thing.  It is something you already know but perhaps you do not "see"
+       it yet:
+
+       If you write down 1234, (no prefix, so it is decimal) you are talking
+       about the number one thousand, two hundred and thirty four. In sort of
+       a formula:
+
+        1 * 1000 = 1000
+        2 *  100 =  200
+        3 *   10 =   30
+        4 *    1 =    4
+
+       This can also be written as:
+
+        1 * 10^3
+        2 * 10^2
+        3 * 10^1
+        4 * 10^0
+
+       where ^ means "to the power of".
+
+       We are using the base 10, and the positions 0,1,2 and 3.  The right-
+       most position should NOT be multiplied with 10. The second from the
+       right should be multiplied one time with 10. The third from the right
+       is multiplied with 10 two times. This continues for whatever positions
+       are used.
+
+       It is the same in all other representations:
+
+       0x1234 will be
+
+        1 * 16^3
+        2 * 16^2
+        3 * 16^1
+        4 * 16^0
+
+       01234 would be
+
+        1 * 8^3
+        2 * 8^2
+        3 * 8^1
+        4 * 8^0
+
+       This example can not be done for binary as that system only uses two
+       symbols. Another example:
+
+       %1010 would be
+
+        1 * 2^3
+        0 * 2^2
+        1 * 2^1
+        0 * 2^0
+
+       It would have been easier to convert it to its hexadecimal form and
+       just translate %1010 into 0xA. After a while you get used to it. You
+       will not need to do any calculations anymore, but just know that 0xA
+       means 10.
+
+       To convert a decimal number into a hexadecimal you could use the next
+       method. It will take some time to be able to do the estimates, but it
+       will be easier when you use the system more frequently. We'll look at
+       yet another way afterwards.
+
+       First you need to know how many positions will be used in the other
+       system. To do so, you need to know the maximum numbers you'll be using.
+       Well, that's not as hard as it looks. In decimal, the maximum number
+       that you can form with two digits is "99". The maximum for three:
+       "999". The next number would need an extra position. Reverse this idea
+       and you will see that the number can be found by taking 10^3 (10*10*10
+       is 1000) minus 1 or 10^2 minus one.
+
+       This can be done for hexadecimal as well:
+
+        16^4 = 0x10000 = 65536
+        16^3 =  0x1000 =  4096
+        16^2 =   0x100 =   256
+        16^1 =    0x10 =    16
+
+       If a number is smaller than 65'536 it will fit in four positions.  If
+       the number is bigger than 4'095, you must use position 4.  How many
+       times you can subtract 4'096 from the number without going below zero
+       is the first digit you write down. This will always be a number from 1
+       to 15 (0x1 to 0xF). Do the same for the other positions.
+
+       Let's try with 41'029. It is smaller than 16^4 but bigger than 16^3-1.
+       This means that we have to use four positions.  We can subtract 16^3
+       from 41'029 ten times without going below zero.  The left-most digit
+       will therefore be "A", so we have 0xA????.  The number is reduced to
+       41'029 - 10*4'096 = 41'029-40'960 = 69.  69 is smaller than 16^3 but
+       not bigger than 16^2-1. The second digit is therefore "0" and we now
+       have 0xA0??.  69 is smaller than 16^2 and bigger than 16^1-1. We can
+       subtract 16^1 (which is just plain 16) four times and write down "4" to
+       get 0xA04?.  Subtract 64 from 69 (69 - 4*16) and the last digit is 5
+       --> 0xA045.
+
+       The other method builds ub the number from the right. Let's try 41'029
+       again.  Divide by 16 and do not use fractions (only whole numbers).
+
+        41'029 / 16 is 2'564 with a remainder of 5. Write down 5.
+        2'564 / 16 is 160 with a remainder of 4. Write the 4 before the 5.
+        160 / 16 is 10 with no remainder. Prepend 45 with 0.
+        10 / 16 is below one. End here and prepend 0xA. End up with 0xA045.
+
+       Which method to use is up to you. Use whatever works for you.  I use
+       them both without being able to tell what method I use in each case, it
+       just depends on the number, I think. Fact is, some numbers will occur
+       frequently while programming. If the number is close to one I am famil-
+       iar with, then I will use the first method (like 32'770 which is into
+       32'768 + 2 and I just know that it is 0x8000 + 0x2 = 0x8002).
+
+       For binary the same approach can be used. The base is 2 and not 16, and
+       the number of positions will grow rapidly. Using the second method has
+       the advantage that you can see very easily if you should write down a
+       zero or a one: if you divide by two the remainder will be zero if it is
+       an even number and one if it is an odd number:
+
+        41029 / 2 = 20514 remainder 1
+        20514 / 2 = 10257 remainder 0
+        10257 / 2 =  5128 remainder 1
+         5128 / 2 =  2564 remainder 0
+         2564 / 2 =  1282 remainder 0
+         1282 / 2 =   641 remainder 0
+          641 / 2 =   320 remainder 1
+          320 / 2 =   160 remainder 0
+          160 / 2 =    80 remainder 0
+           80 / 2 =    40 remainder 0
+           40 / 2 =    20 remainder 0
+           20 / 2 =    10 remainder 0
+           10 / 2 =     5 remainder 0
+            5 / 2 =     2 remainder 1
+            2 / 2 =     1 remainder 0
+            1 / 2 below 0 remainder 1
+
+       Write down the results from right to left: %1010000001000101
+
+       Group by four:
+
+        %1010000001000101
+        %101000000100 0101
+        %10100000 0100 0101
+        %1010 0000 0100 0101
+
+       Convert into hexadecimal: 0xA045
+
+       Group %1010000001000101 by three and convert into octal:
+
+        %1010000001000101
+        %1010000001000 101
+        %1010000001 000 101
+        %1010000 001 000 101
+        %1010 000 001 000 101
+        %1 010 000 001 000 101
+        %001 010 000 001 000 101
+           1   2   0   1   0   5 --> 0120105
+
+        So: %1010000001000101 = 0120105 = 0xA045 = 41029
+        Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029(10)
+        Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029
+
+       At first while adding numbers, you'll convert them to their decimal
+       form and then back into their original form after doing the addition.
+       If you use the other numbering system often, you will see that you'll
+       be able to do arithmetics directly in the base that is used.  In any
+       representation it is the same, add the numbers on the right, write down
+       the right-most digit from the result, remember the other digits and use
+       them in the next round. Continue with the second digit from the right
+       and so on:
+
+           %1010 + %0111 --> 10 + 7 --> 17 --> %00010001
+
+       will become
+
+           %1010
+           %0111 +
+            ||||
+            |||+-- add 0 + 1, result is 1, nothing to remember
+            ||+--- add 1 + 1, result is %10, write down 0 and remember 1
+            |+---- add 0 + 1 + 1(remembered), result = 0, remember 1
+            +----- add 1 + 0 + 1(remembered), result = 0, remember 1
+                   nothing to add, 1 remembered, result = 1
+        --------
+          %10001 is the result, I like to write it as %00010001
+
+       For low values, try to do the calculations yourself, then check them
+       with a calculator. The more you do the calculations yourself, the more
+       you'll find that you didn't make mistakes. In the end, you'll do cal-
+       culi in other bases as easily as you do them in decimal.
+
+       When the numbers get bigger, you'll have to realize that a computer is
+       not called a computer just to have a nice name. There are many differ-
+       ent calculators available, use them. For Unix you could use "bc" which
+       is short for Binary Calculator. It calculates not only in decimal, but
+       in all bases you'll ever want to use (among them Binary).
+
+       For people on Windows: Start the calculator (start->programs->acces-
+       sories->calculator) and if necessary click view->scientific. You now
+       have a scientific calculator and can compute in binary or hexadecimal.

+.Sh "Why this tutorial?"
+.IX Subsection "Why this tutorial?"
+One of the powerful parts of RRDtool is its ability to do all sorts
+of calculations on the data retrieved from its databases. However,
+RRDtool's many options and syntax make it difficult for the average
+user to understand. The manuals are good at explaining what these
+options do; however they do not (and should not) explain in detail
+why they are useful. As with my RRDtool tutorial: if you want a
+simple document in simple language you should read this tutorial.
+If you are happy with the official documentation, you may find this
+document too simple or even boring. If you do choose to read this
+tutorial, I also expect you to have read and fully understand my
+other tutorial.
+.Sh "More reading"
+.IX Subsection "More reading"
+If you have difficulties with the way I try to explain it please read
+Steve Rader's rpntutorial. It may help you understand how this all works.
+.SH "What are CDEFs?"
+.IX Header "What are CDEFs?"
+When retrieving data from an \s-1RRD\s0, you are using a \*(L"\s-1DEF\s0\*(R" to work with
+that data. Think of it as a variable that changes over time (where
+time is the x\-axis). The value of this variable is what is found in
+the database at that particular time and you can't do any
+modifications on it. This is what CDEFs are for: they takes values
+from DEFs and perform calculations on them.
+.SH "Syntax"
+.IX Header "Syntax"
+.Vb 2
+\&   DEF:var_name_1=some.rrd:ds_name:CF
+\&   CDEF:var_name_2=RPN_expression
+.Ve
+.PP
+You first define \*(L"var_name_1\*(R" to be data collected from data source
+\&\*(L"ds_name\*(R" found in \s-1RRD\s0 \*(L"some.rrd\*(R" with consolidation function \*(L"\s-1CF\s0\*(R".
+.PP
+Assume the ifInOctets \s-1SNMP\s0 counter is saved in mrtg.rrd as the \s-1DS\s0 \*(L"in\*(R".
+Then the following \s-1DEF\s0 defines a variable for the average of that
+data source:
+.PP
+.Vb 1
+\&   DEF:inbytes=mrtg.rrd:in:AVERAGE
+.Ve
+.PP
+Say you want to display bits per second (instead of bytes per second
+as stored in the database.)  You have to define a calculation
+(hence \*(L"\s-1CDEF\s0\*(R") on variable \*(L"inbytes\*(R" and use that variable (inbits)
+instead of the original:
+.PP
+.Vb 1
+\&   CDEF:inbits=inbytes,8,*
+.Ve
+.PP
+This tells RRDtool to multiply inbytes by eight to get inbits. I'll
+explain later how this works. In the graphing or printing functions,
+you can now use inbits where you would use inbytes otherwise.
+.PP
+Note that the variable name used in the \s-1CDEF\s0 (inbits) must not be the
+same as the variable named in the \s-1DEF\s0 (inbytes)!
+.SH "RPN-expressions"
+.IX Header "RPN-expressions"
+\&\s-1RPN\s0 is short-hand for Reverse Polish Notation. It works as follows.
+You put the variables or numbers on a stack. You also put operations
+(things\-to\-do) on the stack and this stack is then processed. The result
+will be placed on the stack. At the end, there should be exactly one
+number left: the outcome of the series of operations. If there is not
+exactly one number left, RRDtool will complain loudly.
+.PP
+Above multiplication by eight will look like:
+.IP "1." 4
+Start with an empty stack
+.IP "2." 4
+Put the content of variable inbytes on the stack
+.IP "3." 4
+Put the number eight on the stack
+.IP "4." 4
+Put the operation multiply on the stack
+.IP "5." 4
+Process the stack
+.IP "6." 4
+Retrieve the value from the stack and put it in variable inbits
+.PP
+We will now do an example with real numbers. Suppose the variable
+inbytes would have value 10, the stack would be:
+.IP "1." 4
+||
+.IP "2." 4
+|10|
+.IP "3." 4
+|10|8|
+.IP "4." 4
+|10|8|*|
+.IP "5." 4
+|80|
+.IP "6." 4
+||
+.PP
+Processing the stack (step 5) will retrieve one value from the stack
+(from the right at step 4). This is the operation multiply and this
+takes two values off the stack as input. The result is put back on the
+stack (the value 80 in this case). For multiplication the order doesn't
+matter, but for other operations like subtraction and division it does.
+Generally speaking you have the following order:
+.PP
+.Vb 1
+\&   y = A \- B  \-\->  y=minus(A,B)  \-\->  CDEF:y=A,B,\-
+.Ve
+.PP
+This is not very intuitive (at least most people don't think so). For
+the function f(A,B) you reverse the position of \*(L"f\*(R", but you do not
+reverse the order of the variables.
+.SH "Converting your wishes to RPN"
+.IX Header "Converting your wishes to RPN"
+First, get a clear picture of what you want to do. Break down the problem
+in smaller portions until they cannot be split anymore. Then it is rather
+simple to convert your ideas into \s-1RPN\s0.
+.PP
+Suppose you have several RRDs and would like to add up some counters in
+them. These could be, for instance, the counters for every \s-1WAN\s0 link you
+are monitoring.
+.PP
+You have:
+.PP
+.Vb 3
+\&   router1.rrd with link1in link2in
+\&   router2.rrd with link1in link2in
+\&   router3.rrd with link1in link2in
+.Ve
+.PP
+Suppose you would like to add up all these counters, except for link2in
+inside router2.rrd. You need to do:
+.PP
+(in this example, \*(L"router1.rrd:link1in\*(R" means the \s-1DS\s0 link1in inside the
+\&\s-1RRD\s0 router1.rrd)
+.PP
+.Vb 7
+\&   router1.rrd:link1in
+\&   router1.rrd:link2in
+\&   router2.rrd:link1in
+\&   router3.rrd:link1in
+\&   router3.rrd:link2in
+\&   \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-   +
+\&   (outcome of the sum)
+.Ve
+.PP
+As a mathematical function, this could be written:
+.PP
+\&\f(CW\*(C`add(router1.rrd:link1in , router1.rrd:link2in , router2.rrd:link1in , router3.rrd:link1in , router3.rrd:link2.in)\*(C'\fR
+.PP
+With RRDtool and \s-1RPN\s0, first, define the inputs:
+.PP
+.Vb 5
+\&   DEF:a=router1.rrd:link1in:AVERAGE
+\&   DEF:b=router1.rrd:link2in:AVERAGE
+\&   DEF:c=router2.rrd:link1in:AVERAGE
+\&   DEF:d=router3.rrd:link1in:AVERAGE
+\&   DEF:e=router3.rrd:link2in:AVERAGE
+.Ve
+.PP
+Now, the mathematical function becomes: \f(CW\*(C`add(a,b,c,d,e)\*(C'\fR
+.PP
+In \s-1RPN\s0, there's no operator that sums more than two values so you need
+to do several additions. You add a and b, add c to the result, add d
+to the result and add e to the result.
+.PP
+.Vb 5
+\&   push a:         a     stack contains the value of a
+\&   push b and add: b,+   stack contains the result of a+b
+\&   push c and add: c,+   stack contains the result of a+b+c
+\&   push d and add: d,+   stack contains the result of a+b+c+d
+\&   push e and add: e,+   stack contains the result of a+b+c+d+e
+.Ve
+.PP
+What was calculated here would be written down as:
+.PP
+.Vb 1
+\&   ( ( ( (a+b) + c) + d) + e) >
+.Ve
+.PP
+This is in \s-1RPN:\s0  \f(CW\*(C`CDEF:result=a,b,+,c,+,d,+,e,+\*(C'\fR
+.PP
+This is correct but it can be made more clear to humans. It does
+not matter if you add a to b and then add c to the result or first
+add b to c and then add a to the result. This makes it possible to
+rewrite the \s-1RPN\s0 into \f(CW\*(C`CDEF:result=a,b,c,d,e,+,+,+,+\*(C'\fR which is
+evaluated differently:
+.PP
+.Vb 13
+\&   push value of variable a on the stack: a
+\&   push value of variable b on the stack: a b
+\&   push value of variable c on the stack: a b c
+\&   push value of variable d on the stack: a b c d
+\&   push value of variable e on the stack: a b c d e
+\&   push operator + on the stack:          a b c d e +
+\&   and process it:                        a b c P   (where P == d+e)
+\&   push operator + on the stack:          a b c P +
+\&   and process it:                        a b Q     (where Q == c+P)
+\&   push operator + on the stack:          a b Q +
+\&   and process it:                        a R       (where R == b+Q)
+\&   push operator + on the stack:          a R +
+\&   and process it:                        S         (where S == a+R)
+.Ve
+.PP
+As you can see the \s-1RPN\s0 expression \f(CW\*(C`a,b,c,d,e,+,+,+,+,+\*(C'\fR will evaluate in
+\&\f(CW\*(C`((((d+e)+c)+b)+a)\*(C'\fR and it has the same outcome as \f(CW\*(C`a,b,+,c,+,d,+,e,+\*(C'\fR.
+This is called the commutative law of addition,
+but you may forget this right away, as long as you remember what it
+means.
+.PP
+Now look at an expression that contains a multiplication:
+.PP
+First in normal math: \f(CW\*(C`let result = a+b*c\*(C'\fR. In this case you can't
+choose the order yourself, you have to start with the multiplication
+and then add a to it. You may alter the position of b and c, you must
+not alter the position of a and b.
+.PP
+You have to take this in consideration when converting this expression
+into \s-1RPN\s0. Read it as: \*(L"Add the outcome of b*c to a\*(R" and then it is
+easy to write the \s-1RPN\s0 expression: \f(CW\*(C`result=a,b,c,*,+\*(C'\fR
+Another expression that would return the same: \f(CW\*(C`result=b,c,*,a,+\*(C'\fR
+.PP
+In normal math, you may encounter something like \*(L"a*(b+c)\*(R" and this
+can also be converted into \s-1RPN\s0. The parenthesis just tell you to first
+add b and c, and then multiply a with the result. Again, now it is
+easy to write it in \s-1RPN:\s0 \f(CW\*(C`result=a,b,c,+,*\*(C'\fR. Note that this is very
+similar to one of the expressions in the previous paragraph, only the
+multiplication and the addition changed places.
+.PP
+When you have problems with \s-1RPN\s0 or when RRDtool is complaining, it's
+usually a good thing to write down the stack on a piece of paper
+and see what happens. Have the manual ready and pretend to be RRDtool.
+Just do all the math by hand to see what happens, I'm sure this will
+solve most, if not all, problems you encounter.
+.SH "Some special numbers"
+.IX Header "Some special numbers"
+.Sh "The unknown value"
+.IX Subsection "The unknown value"
+Sometimes collecting your data will fail. This can be very common,
+especially when querying over busy links. RRDtool can be configured
+to allow for one (or even more) unknown value(s) and calculate the missing
+update. You can, for instance, query your device every minute. This is
+creating one so called \s-1PDP\s0 or primary data point per minute. If you
+defined your \s-1RRD\s0 to contain an \s-1RRA\s0 that stores 5\-minute values, you need
+five of those PDPs to create one \s-1CDP\s0 (consolidated data point).
+These PDPs can become unknown in two cases:
+.IP "1." 4
+The updates are too far apart. This is tuned using the \*(L"heartbeat\*(R" setting.
+.IP "2." 4
+The update was set to unknown on purpose by inserting no value (using the
+template option) or by using \*(L"U\*(R" as the value to insert.
+.PP
+When a \s-1CDP\s0 is calculated, another mechanism determines if this \s-1CDP\s0 is valid
+or not. If there are too many PDPs unknown, the \s-1CDP\s0 is unknown as well.
+This is determined by the xff factor. Please note that one unknown counter
+update can result in two unknown PDPs! If you only allow for one unknown
+\&\s-1PDP\s0 per \s-1CDP\s0, this makes the \s-1CDP\s0 go unknown!
+.PP
+Suppose the counter increments with one per second and you retrieve it
+every minute:
+.PP
+.Vb 7
+\&   counter value    resulting rate
+\&   10'000
+\&   10'060            1; (10'060\-10'000)/60 == 1
+\&   10'120            1; (10'120\-10'060)/60 == 1
+\&   unknown           unknown; you don't know the last value
+\&   10'240            unknown; you don't know the previous value
+\&   10'300            1; (10'300\-10'240)/60 == 1
+.Ve
+.PP
+If the \s-1CDP\s0 was to be calculated from the last five updates, it would get
+two unknown PDPs and three known PDPs. If xff would have been set to 0.5
+which by the way is a commonly used factor, the \s-1CDP\s0 would have a known
+value of 1. If xff would have been set to 0.2 then the resulting \s-1CDP\s0
+would be unknown.
+.PP
+You have to decide the proper values for heartbeat, number of PDPs per
+\&\s-1CDP\s0 and the xff factor. As you can see from the previous text they define
+the behavior of your \s-1RRA\s0.
+.Sh "Working with unknown data in your database"
+.IX Subsection "Working with unknown data in your database"
+As you have read in the previous chapter, entries in an \s-1RRA\s0 can be
+set to the unknown value. If you do calculations with this type of
+value, the result has to be unknown too. This means that an expression
+such as \f(CW\*(C`result=a,b,+\*(C'\fR will be unknown if either a or b is unknown.
+It would be wrong to just ignore the unknown value and return the value
+of the other parameter. By doing so, you would assume \*(L"unknown\*(R" means \*(L"zero\*(R"
+and this is not true.
+.PP
+There has been a case where somebody was collecting data for over a year.
+A new piece of equipment was installed, a new \s-1RRD\s0 was created and the
+scripts were changed to add a counter from the old database and a counter
+from the new database. The result was disappointing, a large part of
+the statistics seemed to have vanished mysteriously ...
+They of course didn't, values from the old database (known values) were
+added to values from the new database (unknown values) and the result was
+unknown.
+.PP
+In this case, it is fairly reasonable to use a \s-1CDEF\s0 that alters unknown
+data into zero. The counters of the device were unknown (after all, it
+wasn't installed yet!) but you know that the data rate through the device
+had to be zero (because of the same reason: it was not installed).
+.PP
+There are some examples below that make this change.
+.Sh "Infinity"
+.IX Subsection "Infinity"
+Infinite data is another form of a special number. It cannot be
+graphed because by definition you would never reach the infinite
+value. You can think of positive and negative infinity depending on
+the position relative to zero.
+.PP
+RRDtool is capable of representing (\-not\- graphing!) infinity by stopping
+at its current maximum (for positive infinity) or minimum (for negative
+infinity) without knowing this maximum (minimum).
+.PP
+Infinity in RRDtool is mostly used to draw an \s-1AREA\s0 without knowing its
+vertical dimensions. You can think of it as drawing an \s-1AREA\s0 with an
+infinite height and displaying only the part that is visible in the
+current graph. This is probably a good way to approximate infinity
+and it sure allows for some neat tricks. See below for examples.
+.Sh "Working with unknown data and infinity"
+.IX Subsection "Working with unknown data and infinity"
+Sometimes you would like to discard unknown data and pretend it is zero
+(or any other value for that matter) and sometimes you would like to
+pretend that known data is unknown (to discard known-to-be-wrong data).
+This is why CDEFs have support for unknown data. There are also examples
+available that show unknown data by using infinity.
+.SH "Some examples"
+.IX Header "Some examples"
+.Sh "Example: using a recently created \s-1RRD\s0"
+.IX Subsection "Example: using a recently created RRD"
+You are keeping statistics on your router for over a year now. Recently
+you installed an extra router and you would like to show the combined
+throughput for these two devices.
+.PP
+If you just add up the counters from router.rrd and router2.rrd, you
+will add known data (from router.rrd) to unknown data (from router2.rrd) for
+the bigger part of your stats. You could solve this in a few ways:
+.IP "\(bu" 4
+While creating the new database, fill it with zeros from the start to now.
+You have to make the database start at or before the least recent time in
+the other database.
+.IP "\(bu" 4
+Alternatively, you could use \s-1CDEF\s0 and alter unknown data to zero.
+.PP
+Both methods have their pros and cons. The first method is troublesome and
+if you want to do that you have to figure it out yourself. It is not
+possible to create a database filled with zeros, you have to put them in
+manually. Implementing the second method is described next:
+.PP
+What we want is: \*(L"if the value is unknown, replace it with zero\*(R". This
+could be written in pseudo-code as:  if (value is unknown) then (zero)
+else (value). When reading the rrdgraph manual you notice the \*(L"\s-1UN\s0\*(R"
+function that returns zero or one. You also notice the \*(L"\s-1IF\s0\*(R" function
+that takes zero or one as input.
+.PP
+First look at the \*(L"\s-1IF\s0\*(R" function. It takes three values from the stack,
+the first value is the decision point, the second value is returned to
+the stack if the evaluation is \*(L"true\*(R" and if not, the third value is
+returned to the stack. We want the \*(L"\s-1UN\s0\*(R" function to decide what happens
+so we combine those two functions in one \s-1CDEF\s0.
+.PP
+Lets write down the two possible paths for the \*(L"\s-1IF\s0\*(R" function:
+.PP
+.Vb 2
+\&   if true  return a
+\&   if false return b
+.Ve
+.PP
+In \s-1RPN:\s0  \f(CW\*(C`result=x,a,b,IF\*(C'\fR where \*(L"x\*(R" is either true or false.
+.PP
+Now we have to fill in \*(L"x\*(R", this should be the \*(L"(value is unknown)\*(R" part
+and this is in \s-1RPN:\s0  \f(CW\*(C`result=value,UN\*(C'\fR
+.PP
+We now combine them: \f(CW\*(C`result=value,UN,a,b,IF\*(C'\fR and when we fill in the
+appropriate things for \*(L"a\*(R" and \*(L"b\*(R" we're finished:
+.PP
+\&\f(CW\*(C`CDEF:result=value,UN,0,value,IF\*(C'\fR
+.PP
+You may want to read Steve Rader's \s-1RPN\s0 guide if you have difficulties
+with the way I explained this last example.
+.PP
+If you want to check this \s-1RPN\s0 expression, just mimic RRDtool behavior:
+.PP
+.Vb 4
+\&   For any known value, the expression evaluates as follows:
+\&   CDEF:result=value,UN,0,value,IF  (value,UN) is not true so it becomes 0
+\&   CDEF:result=0,0,value,IF         "IF" will return the 3rd value
+\&   CDEF:result=value                The known value is returned
+.Ve
+.PP
+.Vb 4
+\&   For the unknown value, this happens:
+\&   CDEF:result=value,UN,0,value,IF  (value,UN) is true so it becomes 1
+\&   CDEF:result=1,0,value,IF         "IF" sees 1 and returns the 2nd value
+\&   CDEF:result=0                    Zero is returned
+.Ve
+.PP
+Of course, if you would like to see another value instead of zero, you
+can use that other value.
+.PP
+Eventually, when all unknown data is removed from the \s-1RRD\s0, you may want
+to remove this rule so that unknown data is properly displayed.
+.Sh "Example: better handling of unknown data, by using time"
+.IX Subsection "Example: better handling of unknown data, by using time"
+The above example has one drawback. If you do log unknown data in
+your database after installing your new equipment, it will also be
+translated into zero and therefore you won't see that there was a
+problem. This is not good and what you really want to do is:
+.IP "\(bu" 4
+If there is unknown data, look at the time that this sample was taken.
+.IP "\(bu" 4
+If the unknown value is before time xxx, make it zero.
+.IP "\(bu" 4
+If it is after time xxx, leave it as unknown data.
+.PP
+This is doable: you can compare the time that the sample was taken
+to some known time. Assuming you started to monitor your device on
+Friday September 17, 1999, 00:35:57 \s-1MET\s0 \s-1DST\s0. Translate this time in seconds
+since 1970\-01\-01 and it becomes 937'521'357. If you process unknown values
+that were received after this time, you want to leave them unknown and
+if they were \*(L"received\*(R" before this time, you want to translate them
+into zero (so you can effectively ignore them while adding them to your
+other routers counters).
+.PP
+Translating Friday September 17, 1999, 00:35:57 \s-1MET\s0 \s-1DST\s0 into 937'521'357 can
+be done by, for instance, using gnu date:

+.PP
+You could also dump the database and see where the data starts to be
+known. There are several other ways of doing this, just pick one.
+.PP
+Now we have to create the magic that allows us to process unknown
+values different depending on the time that the sample was taken.
+This is a three step process:
+.IP "1." 4
+If the timestamp of the value is after 937'521'357, leave it as is.
+.IP "2." 4
+If the value is a known value, leave it as is.
+.IP "3." 4
+Change the unknown value into zero.
+.PP
+Lets look at part one:
+.PP
+.Vb 1
+\&    if (true) return the original value
+.Ve
+.PP
+We rewrite this:
+.PP
+.Vb 2
+\&    if (true) return "a"
+\&    if (false) return "b"
+.Ve
+.PP
+We need to calculate true or false from step 1. There is a function
+available that returns the timestamp for the current sample. It is
+called, how surprisingly, \*(L"\s-1TIME\s0\*(R". This time has to be compared to
+a constant number, we need \*(L"\s-1GT\s0\*(R". The output of \*(L"\s-1GT\s0\*(R" is true or false
+and this is good input to \*(L"\s-1IF\s0\*(R". We want \*(L"if (time > 937521357) then
+(return a) else (return b)\*(R".
+.PP
+This process was already described thoroughly in the previous chapter
+so lets do it quick:
+.PP
+.Vb 4
+\&   if (x) then a else b
+\&      where x represents "time>937521357"

+\&   substitute b         \-\-> TIME,937521357,GT,value,value,UN,0,value,IF,IF

+We end up with:
+\&\f(CW\*(C`CDEF:result=TIME,937521357,GT,value,value,UN,0,value,IF,IF\*(C'\fR

+This looks very complex, however, as you can see, it was not too hard to
+come up with.
+.Sh "Example: Pretending weird data isn't there"
+.IX Subsection "Example: Pretending weird data isn't there"
+Suppose you have a problem that shows up as huge spikes in your graph.
+You know this happens and why, so you decide to work around the problem.
+Perhaps you're using your network to do a backup at night and by doing
+so you get almost 10mb/s while the rest of your network activity does
+not produce numbers higher than 100kb/s.
+.PP
+There are two options:
+.IP "1." 4
+If the number exceeds 100kb/s it is wrong and you want it masked out
+by changing it into unknown.
+.IP "2." 4
+You don't want the graph to show more than 100kb/s.
+.PP
+Pseudo code: if (number > 100) then unknown else number
+or
+Pseudo code: if (number > 100) then 100 else number.
+.PP
+The second \*(L"problem\*(R" may also be solved by using the rigid option of
+RRDtool graph, however this has not the same result. In this example
+you can end up with a graph that does autoscaling. Also, if you use
+the numbers to display maxima they will be set to 100kb/s.
+.PP
+We use \*(L"\s-1IF\s0\*(R" and \*(L"\s-1GT\s0\*(R" again. \*(L"if (x) then (y) else (z)\*(R" is written
+down as \*(L"CDEF:result=x,y,z,IF\*(R"; now fill in x, y and z.
+For x you fill in \*(L"number greater than 100kb/s\*(R" becoming
+\&\*(L"number,100000,GT\*(R" (kilo is 1'000 and b/s is what we measure!).
+The \*(L"z\*(R" part is \*(L"number\*(R" in both cases and the \*(L"y\*(R" part is either
+\&\*(L"\s-1UNKN\s0\*(R" for unknown or \*(L"100000\*(R" for 100kb/s.
+.PP
+The two \s-1CDEF\s0 expressions would be:
+.PP
+.Vb 2

+\&    CDEF:result=number,100000,GT,100000,number,IF
+.Ve
+.Sh "Example: working on a certain time span"
+.IX Subsection "Example: working on a certain time span"
+If you want a graph that spans a few weeks, but would only want to
+see some routers' data for one week, you need to \*(L"hide\*(R" the rest of
+the time frame. Don't ask me when this would be useful, it's just
+here for the example :)
+.PP
+We need to compare the time stamp to a begin date and an end date.

+.PP
+.Vb 2

+\&        TIME,endtime,LE
+.Ve
+.PP
+These two parts of the \s-1CDEF\s0 produce either 0 for false or 1 for true.
+We can now check if they are both 0 (or 1) using a few \s-1IF\s0 statements
+but, as Wataru Satoh pointed out, we can use the \*(L"*\*(R" or \*(L"+\*(R" functions
+as logical \s-1AND\s0 and logical \s-1OR\s0.
+.PP
+For \*(L"*\*(R", the result will be zero (false) if either one of the two
+operators is zero.  For \*(L"+\*(R", the result will only be false (0) when
+two false (0) operators will be added.  Warning: *any* number not
+equal to 0 will be considered \*(L"true\*(R". This means that, for instance,
+\&\*(L"\-1,1,+\*(R" (which should be \*(L"true or true\*(R") will become \s-1FALSE\s0 ...
+In other words, use \*(L"+\*(R" only if you know for sure that you have positive
+numbers (or zero) only.
+.PP

+If one of them doesn't give an answer (or an incorrect one) you get \*(L"NaN\*(R"

+and the (z) part of the function returns \*(L"\s-1UNKN\s0\*(R".
+.PP
+The logic is: if (allusers == unknown) then return \s-1INF\s0 else return \s-1UNKN\s0.
+.PP
+You can now use \s-1AREA\s0 to display this \*(L"wrongdata\*(R" in bright red. If it
+is unknown (because allusers is known) then the red \s-1AREA\s0 won't show up.

+The end result is that we have added \*(L"idat1\*(R" and \*(L"idat2\*(R" and in the

+.PP
+.Vb 1

+.Ve
+.PP
+This \s-1RPN\s0 takes the value of \*(L"val4\*(R" as input and then immediately
+removes it from the stack using \*(L"\s-1POP\s0\*(R". The stack is now empty but
+as a side effect we now know the time that this sample was taken.
+This time is put on the stack by the \*(L"\s-1TIME\s0\*(R" function.
+.PP
+\&\*(L"\s-1TIME\s0,7200,%\*(R" takes the modulo of time and 7'200 (which is two hours).
+The resulting value on the stack will be a number in the range from
+0 to 7199.
+.PP
+For people who don't know the modulo function: it is the remainder
+after an integer division. If you divide 16 by 3, the answer would
+be 5 and the remainder would be 1. So, \*(L"16,3,%\*(R" returns 1.
+.PP
+We have the result of \*(L"\s-1TIME\s0,7200,%\*(R" on the stack, lets call this
+\&\*(L"a\*(R". The start of the \s-1RPN\s0 has become \*(L"a,3600,LE\*(R" and this checks
+if \*(L"a\*(R" is less or equal than \*(L"3600\*(R". It is true half of the time.
+We now have to process the rest of the \s-1RPN\s0 and this is only a simple
+\&\*(L"\s-1IF\s0\*(R" function that returns either \*(L"\s-1INF\s0\*(R" or \*(L"\s-1UNKN\s0\*(R" depending on the
+time. This is returned to variable \*(L"background\*(R".
+.PP
+The second \s-1CDEF\s0 has been discussed earlier in this document so we
+won't do that here.
+.PP
+Now you can draw the different layers. Start with the background
+that is either unknown (nothing to see) or infinite (the whole
+positive part of the graph gets filled).
+.PP
+Next you draw the data on top of this background, it will overlay
+the background. Suppose one of val1..val4 would be unknown, in that
+case you end up with only three bars stacked on top of each other.
+You don't want to see this because the data is only valid when all
+four variables are valid. This is why you use the second \s-1CDEF\s0, it
+will overlay the data with an \s-1AREA\s0 so the data cannot be seen anymore.
+.PP
+If your data can also have negative values you also need to overwrite
+the other half of your graph. This can be done in a relatively simple
+way: what you need is the \*(L"wipeout\*(R" variable and place a negative
+sign before it:  \*(L"CDEF:wipeout2=wipeout,\-1,*\*(R"

+<h2><a name="why_this_tutorial">Why this tutorial?</a></h2>
+<p>One of the powerful parts of RRDtool is its ability to do all sorts
+of calculations on the data retrieved from its databases. However,
+RRDtool's many options and syntax make it difficult for the average
+user to understand. The manuals are good at explaining what these
+options do; however they do not (and should not) explain in detail
+why they are useful. As with my RRDtool tutorial: if you want a
+simple document in simple language you should read this tutorial.
+If you are happy with the official documentation, you may find this
+document too simple or even boring. If you do choose to read this
+tutorial, I also expect you to have read and fully understand my
+other tutorial.</p>
+<p>

+<p>If you have difficulties with the way I try to explain it please read
+Steve Rader's <a href="././rpntutorial.html">the rpntutorial manpage</a>. It may help you understand how this all works.</p>

+</p>
+<hr />
+<h1><a name="what_are_cdefs">What are CDEFs?</a></h1>
+<p>When retrieving data from an RRD, you are using a ``DEF'' to work with
+that data. Think of it as a variable that changes over time (where
+time is the x-axis). The value of this variable is what is found in
+the database at that particular time and you can't do any
+modifications on it. This is what CDEFs are for: they takes values
+from DEFs and perform calculations on them.</p>
+<p>
+</p>
+<hr />
+<h1><a name="syntax">Syntax</a></h1>
+<pre>
+   DEF:var_name_1=some.rrd:ds_name:CF
+   CDEF:var_name_2=RPN_expression</pre>
+<p>You first define ``var_name_1'' to be data collected from data source
+``ds_name'' found in RRD ``some.rrd'' with consolidation function ``CF''.</p>
+<p>Assume the ifInOctets SNMP counter is saved in mrtg.rrd as the DS ``in''.
+Then the following DEF defines a variable for the average of that
+data source:</p>
+<pre>
+   DEF:inbytes=mrtg.rrd:in:AVERAGE</pre>
+<p>Say you want to display bits per second (instead of bytes per second
+as stored in the database.)  You have to define a calculation
+(hence ``CDEF'') on variable ``inbytes'' and use that variable (inbits)
+instead of the original:</p>
+<pre>
+   CDEF:inbits=inbytes,8,*</pre>
+<p>This tells RRDtool to multiply inbytes by eight to get inbits. I'll
+explain later how this works. In the graphing or printing functions,
+you can now use inbits where you would use inbytes otherwise.</p>
+<p>Note that the variable name used in the CDEF (inbits) must not be the
+same as the variable named in the DEF (inbytes)!</p>
+<p>
+</p>
+<hr />
+<h1><a name="rpnexpressions">RPN-expressions</a></h1>
+<p>RPN is short-hand for Reverse Polish Notation. It works as follows.
+You put the variables or numbers on a stack. You also put operations
+(things-to-do) on the stack and this stack is then processed. The result
+will be placed on the stack. At the end, there should be exactly one
+number left: the outcome of the series of operations. If there is not
+exactly one number left, RRDtool will complain loudly.</p>
+<p>Above multiplication by eight will look like:</p>
+<ol>
+<li>
+<p>Start with an empty stack</p>
+</li>
+<li>
+<p>Put the content of variable inbytes on the stack</p>
+</li>
+<li>
+<p>Put the number eight on the stack</p>
+</li>
+<li>
+<p>Put the operation multiply on the stack</p>
+</li>
+<li>
+<p>Process the stack</p>
+</li>
+<li>
+<p>Retrieve the value from the stack and put it in variable inbits</p>
+</li>
+</ol>
+<p>We will now do an example with real numbers. Suppose the variable
+inbytes would have value 10, the stack would be:</p>
+<ol>
+<li>
+<p>||</p>
+</li>
+<li>
+<p>|10|</p>
+</li>
+<li>
+<p>|10|8|</p>
+</li>
+<li>
+<p>|10|8|*|</p>
+</li>
+<li>
+<p>|80|</p>
+</li>
+<li>
+<p>||</p>
+</li>
+</ol>
+<p>Processing the stack (step 5) will retrieve one value from the stack
+(from the right at step 4). This is the operation multiply and this
+takes two values off the stack as input. The result is put back on the
+stack (the value 80 in this case). For multiplication the order doesn't
+matter, but for other operations like subtraction and division it does.
+Generally speaking you have the following order:</p>
+<pre>
+   y = A - B  --&gt;  y=minus(A,B)  --&gt;  CDEF:y=A,B,-</pre>
+<p>This is not very intuitive (at least most people don't think so). For
+the function <code>f(A,B)</code> you reverse the position of ``f'', but you do not
+reverse the order of the variables.</p>
+<p>
+</p>
+<hr />
+<h1><a name="converting_your_wishes_to_rpn">Converting your wishes to RPN</a></h1>
+<p>First, get a clear picture of what you want to do. Break down the problem
+in smaller portions until they cannot be split anymore. Then it is rather
+simple to convert your ideas into RPN.</p>
+<p>Suppose you have several RRDs and would like to add up some counters in
+them. These could be, for instance, the counters for every WAN link you
+are monitoring.</p>
+<p>You have:</p>
+<pre>
+   router1.rrd with link1in link2in
+   router2.rrd with link1in link2in
+   router3.rrd with link1in link2in</pre>
+<p>Suppose you would like to add up all these counters, except for link2in
+inside router2.rrd. You need to do:</p>
+<p>(in this example, ``router1.rrd:link1in'' means the DS link1in inside the
+RRD router1.rrd)</p>
+<pre>
+   router1.rrd:link1in
+   router1.rrd:link2in
+   router2.rrd:link1in
+   router3.rrd:link1in
+   router3.rrd:link2in
+   --------------------   +
+   (outcome of the sum)</pre>
+<p>As a mathematical function, this could be written:</p>
+<p><code>add(router1.rrd:link1in , router1.rrd:link2in , router2.rrd:link1in , router3.rrd:link1in , router3.rrd:link2.in)</code></p>
+<p>With RRDtool and RPN, first, define the inputs:</p>
+<pre>
+   DEF:a=router1.rrd:link1in:AVERAGE
+   DEF:b=router1.rrd:link2in:AVERAGE
+   DEF:c=router2.rrd:link1in:AVERAGE
+   DEF:d=router3.rrd:link1in:AVERAGE
+   DEF:e=router3.rrd:link2in:AVERAGE</pre>
+<p>Now, the mathematical function becomes: <code>add(a,b,c,d,e)</code></p>
+<p>In RPN, there's no operator that sums more than two values so you need
+to do several additions. You add a and b, add c to the result, add d
+to the result and add e to the result.</p>
+<pre>
+   push a:         a     stack contains the value of a
+   push b and add: b,+   stack contains the result of a+b
+   push c and add: c,+   stack contains the result of a+b+c
+   push d and add: d,+   stack contains the result of a+b+c+d
+   push e and add: e,+   stack contains the result of a+b+c+d+e</pre>
+<p>What was calculated here would be written down as:</p>
+<pre>
+   ( ( ( (a+b) + c) + d) + e) &gt;</pre>
+<p>This is in RPN:  <code>CDEF:result=a,b,+,c,+,d,+,e,+</code></p>
+<p>This is correct but it can be made more clear to humans. It does
+not matter if you add a to b and then add c to the result or first
+add b to c and then add a to the result. This makes it possible to
+rewrite the RPN into <code>CDEF:result=a,b,c,d,e,+,+,+,+</code> which is
+evaluated differently:</p>
+<pre>
+   push value of variable a on the stack: a
+   push value of variable b on the stack: a b
+   push value of variable c on the stack: a b c
+   push value of variable d on the stack: a b c d
+   push value of variable e on the stack: a b c d e
+   push operator + on the stack:          a b c d e +
+   and process it:                        a b c P   (where P == d+e)
+   push operator + on the stack:          a b c P +
+   and process it:                        a b Q     (where Q == c+P)
+   push operator + on the stack:          a b Q +
+   and process it:                        a R       (where R == b+Q)
+   push operator + on the stack:          a R +
+   and process it:                        S         (where S == a+R)</pre>
+<p>As you can see the RPN expression <code>a,b,c,d,e,+,+,+,+,+</code> will evaluate in
+<code>((((d+e)+c)+b)+a)</code> and it has the same outcome as <code>a,b,+,c,+,d,+,e,+</code>.
+This is called the commutative law of addition,
+but you may forget this right away, as long as you remember what it
+means.</p>
+<p>Now look at an expression that contains a multiplication:</p>
+<p>First in normal math: <code>let result = a+b*c</code>. In this case you can't
+choose the order yourself, you have to start with the multiplication
+and then add a to it. You may alter the position of b and c, you must
+not alter the position of a and b.</p>
+<p>You have to take this in consideration when converting this expression
+into RPN. Read it as: ``Add the outcome of b*c to a'' and then it is
+easy to write the RPN expression: <code>result=a,b,c,*,+</code>
+Another expression that would return the same: <code>result=b,c,*,a,+</code></p>
+<p>In normal math, you may encounter something like ``a*(b+c)'' and this
+can also be converted into RPN. The parenthesis just tell you to first
+add b and c, and then multiply a with the result. Again, now it is
+easy to write it in RPN: <code>result=a,b,c,+,*</code>. Note that this is very
+similar to one of the expressions in the previous paragraph, only the
+multiplication and the addition changed places.</p>
+<p>When you have problems with RPN or when RRDtool is complaining, it's
+usually a good thing to write down the stack on a piece of paper
+and see what happens. Have the manual ready and pretend to be RRDtool.
+Just do all the math by hand to see what happens, I'm sure this will
+solve most, if not all, problems you encounter.</p>
+<p>
+</p>
+<hr />
+<h1><a name="some_special_numbers">Some special numbers</a></h1>
+<p>
+</p>
+<h2><a name="the_unknown_value">The unknown value</a></h2>
+<p>Sometimes collecting your data will fail. This can be very common,
+especially when querying over busy links. RRDtool can be configured
+to allow for one (or even more) unknown <code>value(s)</code> and calculate the missing
+update. You can, for instance, query your device every minute. This is
+creating one so called PDP or primary data point per minute. If you
+defined your RRD to contain an RRA that stores 5-minute values, you need
+five of those PDPs to create one CDP (consolidated data point).
+These PDPs can become unknown in two cases:</p>
+<ol>
+<li>
+<p>The updates are too far apart. This is tuned using the ``heartbeat'' setting.</p>
+</li>
+<li>
+<p>The update was set to unknown on purpose by inserting no value (using the
+template option) or by using ``U'' as the value to insert.</p>
+</li>
+</ol>
+<p>When a CDP is calculated, another mechanism determines if this CDP is valid
+or not. If there are too many PDPs unknown, the CDP is unknown as well.
+This is determined by the xff factor. Please note that one unknown counter
+update can result in two unknown PDPs! If you only allow for one unknown
+PDP per CDP, this makes the CDP go unknown!</p>
+<p>Suppose the counter increments with one per second and you retrieve it
+every minute:</p>
+<pre>
+   counter value    resulting rate
+   10'000
+   10'060            1; (10'060-10'000)/60 == 1
+   10'120            1; (10'120-10'060)/60 == 1
+   unknown           unknown; you don't know the last value
+   10'240            unknown; you don't know the previous value
+   10'300            1; (10'300-10'240)/60 == 1</pre>
+<p>If the CDP was to be calculated from the last five updates, it would get
+two unknown PDPs and three known PDPs. If xff would have been set to 0.5
+which by the way is a commonly used factor, the CDP would have a known
+value of 1. If xff would have been set to 0.2 then the resulting CDP
+would be unknown.</p>
+<p>You have to decide the proper values for heartbeat, number of PDPs per
+CDP and the xff factor. As you can see from the previous text they define
+the behavior of your RRA.</p>
+<p>
+</p>
+<h2><a name="working_with_unknown_data_in_your_database">Working with unknown data in your database</a></h2>
+<p>As you have read in the previous chapter, entries in an RRA can be
+set to the unknown value. If you do calculations with this type of
+value, the result has to be unknown too. This means that an expression
+such as <code>result=a,b,+</code> will be unknown if either a or b is unknown.
+It would be wrong to just ignore the unknown value and return the value
+of the other parameter. By doing so, you would assume ``unknown'' means ``zero''
+and this is not true.</p>
+<p>There has been a case where somebody was collecting data for over a year.
+A new piece of equipment was installed, a new RRD was created and the
+scripts were changed to add a counter from the old database and a counter
+from the new database. The result was disappointing, a large part of
+the statistics seemed to have vanished mysteriously ...
+They of course didn't, values from the old database (known values) were
+added to values from the new database (unknown values) and the result was
+unknown.</p>
+<p>In this case, it is fairly reasonable to use a CDEF that alters unknown
+data into zero. The counters of the device were unknown (after all, it
+wasn't installed yet!) but you know that the data rate through the device
+had to be zero (because of the same reason: it was not installed).</p>
+<p>There are some examples below that make this change.</p>
+<p>
+</p>
+<h2><a name="infinity">Infinity</a></h2>
+<p>Infinite data is another form of a special number. It cannot be
+graphed because by definition you would never reach the infinite
+value. You can think of positive and negative infinity depending on
+the position relative to zero.</p>
+<p>RRDtool is capable of representing (-not- graphing!) infinity by stopping
+at its current maximum (for positive infinity) or minimum (for negative
+infinity) without knowing this maximum (minimum).</p>
+<p>Infinity in RRDtool is mostly used to draw an AREA without knowing its
+vertical dimensions. You can think of it as drawing an AREA with an
+infinite height and displaying only the part that is visible in the
+current graph. This is probably a good way to approximate infinity
+and it sure allows for some neat tricks. See below for examples.</p>
+<p>
+</p>
+<h2><a name="working_with_unknown_data_and_infinity">Working with unknown data and infinity</a></h2>
+<p>Sometimes you would like to discard unknown data and pretend it is zero
+(or any other value for that matter) and sometimes you would like to
+pretend that known data is unknown (to discard known-to-be-wrong data).
+This is why CDEFs have support for unknown data. There are also examples
+available that show unknown data by using infinity.</p>
+<p>
+</p>
+<hr />
+<h1><a name="some_examples">Some examples</a></h1>
+<p>
+</p>
+<h2><a name="example__using_a_recently_created_rrd">Example: using a recently created RRD</a></h2>
+<p>You are keeping statistics on your router for over a year now. Recently
+you installed an extra router and you would like to show the combined
+throughput for these two devices.</p>
+<p>If you just add up the counters from router.rrd and router2.rrd, you
+will add known data (from router.rrd) to unknown data (from router2.rrd) for
+the bigger part of your stats. You could solve this in a few ways:</p>
+<ul>
+<li>
+<p>While creating the new database, fill it with zeros from the start to now.
+You have to make the database start at or before the least recent time in
+the other database.</p>
+</li>
+<li>
+<p>Alternatively, you could use CDEF and alter unknown data to zero.</p>
+</li>
+</ul>
+<p>Both methods have their pros and cons. The first method is troublesome and
+if you want to do that you have to figure it out yourself. It is not
+possible to create a database filled with zeros, you have to put them in
+manually. Implementing the second method is described next:</p>
+<p>What we want is: ``if the value is unknown, replace it with zero''. This
+could be written in pseudo-code as:  if (value is unknown) then (zero)
+else (value). When reading the <a href="././rrdgraph.html">the rrdgraph manpage</a> manual you notice the ``UN''
+function that returns zero or one. You also notice the ``IF'' function
+that takes zero or one as input.</p>
+<p>First look at the ``IF'' function. It takes three values from the stack,
+the first value is the decision point, the second value is returned to
+the stack if the evaluation is ``true'' and if not, the third value is
+returned to the stack. We want the ``UN'' function to decide what happens
+so we combine those two functions in one CDEF.</p>
+<p>Lets write down the two possible paths for the ``IF'' function:</p>
+<pre>
+   if true  return a
+   if false return b</pre>
+<p>In RPN:  <code>result=x,a,b,IF</code> where ``x'' is either true or false.</p>
+<p>Now we have to fill in ``x'', this should be the ``(value is unknown)'' part
+and this is in RPN:  <code>result=value,UN</code></p>
+<p>We now combine them: <code>result=value,UN,a,b,IF</code> and when we fill in the
+appropriate things for ``a'' and ``b'' we're finished:</p>
+<p><code>CDEF:result=value,UN,0,value,IF</code></p>
+<p>You may want to read Steve Rader's RPN guide if you have difficulties
+with the way I explained this last example.</p>
+<p>If you want to check this RPN expression, just mimic RRDtool behavior:</p>
+<pre>
+   For any known value, the expression evaluates as follows:
+   CDEF:result=value,UN,0,value,IF  (value,UN) is not true so it becomes 0
+   CDEF:result=0,0,value,IF         &quot;IF&quot; will return the 3rd value
+   CDEF:result=value                The known value is returned</pre>
+<pre>
+   For the unknown value, this happens:
+   CDEF:result=value,UN,0,value,IF  (value,UN) is true so it becomes 1
+   CDEF:result=1,0,value,IF         &quot;IF&quot; sees 1 and returns the 2nd value
+   CDEF:result=0                    Zero is returned</pre>
+<p>Of course, if you would like to see another value instead of zero, you
+can use that other value.</p>
+<p>Eventually, when all unknown data is removed from the RRD, you may want
+to remove this rule so that unknown data is properly displayed.</p>
+<p>
+</p>
+<h2><a name="example__better_handling_of_unknown_data__by_using_time">Example: better handling of unknown data, by using time</a></h2>
+<p>The above example has one drawback. If you do log unknown data in
+your database after installing your new equipment, it will also be
+translated into zero and therefore you won't see that there was a
+problem. This is not good and what you really want to do is:</p>
+<ul>
+<li>
+<p>If there is unknown data, look at the time that this sample was taken.</p>
+</li>
+<li>
+<p>If the unknown value is before time xxx, make it zero.</p>
+</li>
+<li>
+<p>If it is after time xxx, leave it as unknown data.</p>
+</li>
+</ul>
+<p>This is doable: you can compare the time that the sample was taken
+to some known time. Assuming you started to monitor your device on
+Friday September 17, 1999, 00:35:57 MET DST. Translate this time in seconds
+since 1970-01-01 and it becomes 937'521'357. If you process unknown values
+that were received after this time, you want to leave them unknown and
+if they were ``received'' before this time, you want to translate them
+into zero (so you can effectively ignore them while adding them to your
+other routers counters).</p>
+<p>Translating Friday September 17, 1999, 00:35:57 MET DST into 937'521'357 can
+be done by, for instance, using gnu date:</p>
+<pre>
+   date -d &quot;19990917 00:35:57&quot; +%s</pre>
+<p>You could also dump the database and see where the data starts to be
+known. There are several other ways of doing this, just pick one.</p>
+<p>Now we have to create the magic that allows us to process unknown
+values different depending on the time that the sample was taken.
+This is a three step process:</p>
+<ol>
+<li>
+<p>If the timestamp of the value is after 937'521'357, leave it as is.</p>
+</li>
+<li>
+<p>If the value is a known value, leave it as is.</p>
+</li>
+<li>
+<p>Change the unknown value into zero.</p>
+</li>
+</ol>
+<p>Lets look at part one:</p>
+<pre>
+    if (true) return the original value</pre>
+<p>We rewrite this:</p>
+<pre>
+    if (true) return &quot;a&quot;
+    if (false) return &quot;b&quot;</pre>
+<p>We need to calculate true or false from step 1. There is a function
+available that returns the timestamp for the current sample. It is
+called, how surprisingly, ``TIME''. This time has to be compared to
+a constant number, we need ``GT''. The output of ``GT'' is true or false
+and this is good input to ``IF''. We want ``if (time &gt; 937521357) then
+(return a) else (return b)''.</p>
+<p>This process was already described thoroughly in the previous chapter
+so lets do it quick:</p>
+<pre>
+   if (x) then a else b
+      where x represents &quot;time&gt;937521357&quot;
+      where a represents the original value
+      where b represents the outcome of the previous example</pre>
+<pre>
+   time&gt;937521357       --&gt; TIME,937521357,GT</pre>
+<pre>
+   if (x) then a else b --&gt; x,a,b,IF
+   substitute x         --&gt; TIME,937521357,GT,a,b,IF
+   substitute a         --&gt; TIME,937521357,GT,value,b,IF
+   substitute b         --&gt; TIME,937521357,GT,value,value,UN,0,value,IF,IF</pre>
+<p>We end up with:
+<code>CDEF:result=TIME,937521357,GT,value,value,UN,0,value,IF,IF</code></p>
+<p>This looks very complex, however, as you can see, it was not too hard to
+come up with.</p>
+<p>

+<h2><a name="example__pretending_weird_data_isn_t_there">Example: Pretending weird data isn't there</a></h2>
+<p>Suppose you have a problem that shows up as huge spikes in your graph.
+You know this happens and why, so you decide to work around the problem.
+Perhaps you're using your network to do a backup at night and by doing
+so you get almost 10mb/s while the rest of your network activity does
+not produce numbers higher than 100kb/s.</p>
+<p>There are two options:</p>
+<ol>
+<li>
+<p>If the number exceeds 100kb/s it is wrong and you want it masked out
+by changing it into unknown.</p>
+</li>
+<li>
+<p>You don't want the graph to show more than 100kb/s.</p>
+</li>
+</ol>
+<p>Pseudo code: if (number &gt; 100) then unknown else number
+or
+Pseudo code: if (number &gt; 100) then 100 else number.</p>
+<p>The second ``problem'' may also be solved by using the rigid option of
+RRDtool graph, however this has not the same result. In this example
+you can end up with a graph that does autoscaling. Also, if you use
+the numbers to display maxima they will be set to 100kb/s.</p>
+<p>We use ``IF'' and ``GT'' again. ``if (x) then (y) else (z)'' is written
+down as ``CDEF:result=x,y,z,IF''; now fill in x, y and z.
+For x you fill in ``number greater than 100kb/s'' becoming
+``number,100000,GT'' (kilo is 1'000 and b/s is what we measure!).
+The ``z'' part is ``number'' in both cases and the ``y'' part is either
+``UNKN'' for unknown or ``100000'' for 100kb/s.</p>
+<p>The two CDEF expressions would be:</p>
+<pre>
+    CDEF:result=number,100000,GT,UNKN,number,IF
+    CDEF:result=number,100000,GT,100000,number,IF</pre>
+<p>
+</p>
+<h2><a name="example__working_on_a_certain_time_span">Example: working on a certain time span</a></h2>
+<p>If you want a graph that spans a few weeks, but would only want to
+see some routers' data for one week, you need to ``hide'' the rest of
+the time frame. Don't ask me when this would be useful, it's just
+here for the example :)</p>
+<p>We need to compare the time stamp to a begin date and an end date.
+Comparing isn't difficult:</p>
+<pre>
+        TIME,begintime,GE
+        TIME,endtime,LE</pre>
+<p>These two parts of the CDEF produce either 0 for false or 1 for true.
+We can now check if they are both 0 (or 1) using a few IF statements
+but, as Wataru Satoh pointed out, we can use the ``*'' or ``+'' functions
+as logical AND and logical OR.</p>
+<p>For ``*'', the result will be zero (false) if either one of the two
+operators is zero.  For ``+'', the result will only be false (0) when
+two false (0) operators will be added.  Warning: *any* number not
+equal to 0 will be considered ``true''. This means that, for instance,
+``-1,1,+'' (which should be ``true or true'') will become FALSE ...
+In other words, use ``+'' only if you know for sure that you have positive
+numbers (or zero) only.</p>
+<p>Let's compile the complete CDEF:</p>
+<pre>
+        DEF:ds0=router1.rrd:AVERAGE
+        CDEF:ds0modified=TIME,begintime,GE,TIME,endtime,LE,*,UNKN,ds0,IF</pre>
+<p>This will return the value of ds0 if both comparisons return true. You
+could also do it the other way around:</p>
+<pre>
+        DEF:ds0=router1.rrd:AVERAGE
+        CDEF:ds0modified=TIME,begintime,LT,TIME,endtime,GT,+,UNKN,ds0,IF</pre>
+<p>This will return an UNKNOWN if either comparison returns true.</p>
+<p>
+</p>
+<h2><a name="example__you_suspect_to_have_problems_and_want_to_see_unknown_data_">Example: You suspect to have problems and want to see unknown data.</a></h2>
+<p>Suppose you add up the number of active users on several terminal servers.
+If one of them doesn't give an answer (or an incorrect one) you get ``NaN''
+in the database (``Not a Number'') and NaN is evaluated as Unknown.</p>
+<p>In this case, you would like to be alerted to it and the sum of the
+remaining values is of no value to you.</p>
+<p>It would be something like:</p>
+<pre>
+    DEF:users1=location1.rrd:onlineTS1:LAST
+    DEF:users2=location1.rrd:onlineTS2:LAST
+    DEF:users3=location2.rrd:onlineTS1:LAST
+    DEF:users4=location2.rrd:onlineTS2:LAST
+    CDEF:allusers=users1,users2,users3,users4,+,+,+</pre>
+<p>If you now plot allusers, unknown data in one of users1..users4 will
+show up as a gap in your graph. You want to modify this to show a
+bright red line, not a gap.</p>
+<p>Define an extra CDEF that is unknown if all is okay and is infinite if
+there is an unknown value:</p>
+<pre>
+    CDEF:wrongdata=allusers,UN,INF,UNKN,IF</pre>
+<p>``allusers,UN'' will evaluate to either true or false, it is the (x) part
+of the ``IF'' function and it checks if allusers is unknown.
+The (y) part of the ``IF'' function is set to ``INF'' (which means infinity)
+and the (z) part of the function returns ``UNKN''.</p>
+<p>The logic is: if (allusers == unknown) then return INF else return UNKN.</p>
+<p>You can now use AREA to display this ``wrongdata'' in bright red. If it
+is unknown (because allusers is known) then the red AREA won't show up.
+If the value is INF (because allusers is unknown) then the red AREA will
+be filled in on the graph at that particular time.</p>

+   AREA:wrongdata#FF0000:unknown data</pre>
+<p>
+</p>
+<h2><a name="same_example_useful_with_stacked_data_">Same example useful with STACKed data:</a></h2>
+<p>If you use stack in the previous example (as I would do) then you don't
+add up the values. Therefore, there is no relationship between the
+four values and you don't get a single value to test.
+Suppose users3 would be unknown at one point in time: users1 is plotted,
+users2 is stacked on top of users1, users3 is unknown and therefore
+nothing happens, users4 is stacked on top of users2.
+Add the extra CDEFs anyway and use them to overlay the ``normal'' graph:</p>
+<pre>
+   DEF:users1=location1.rrd:onlineTS1:LAST
+   DEF:users2=location1.rrd:onlineTS2:LAST
+   DEF:users3=location2.rrd:onlineTS1:LAST
+   DEF:users4=location2.rrd:onlineTS2:LAST
+   CDEF:allusers=users1,users2,users3,users4,+,+,+
+   CDEF:wrongdata=allusers,UN,INF,UNKN,IF
+   AREA:users1#0000FF:users at ts1
+   STACK:users2#00FF00:users at ts2
+   STACK:users3#00FFFF:users at ts3
+   STACK:users4#FFFF00:users at ts4
+   AREA:wrongdata#FF0000:unknown data</pre>
+<p>If there is unknown data in one of users1..users4, the ``wrongdata'' AREA
+will be drawn and because it starts at the X-axis and has infinite height
+it will effectively overwrite the STACKed parts.</p>
+<p>You could combine the two CDEF lines into one (we don't use ``allusers'')
+if you like.  But there are good reasons for writing two CDEFS:</p>
+<ul>
+<li>
+<p>It improves the readability of the script.</p>
+</li>
+<li>
+<p>It can be used inside GPRINT to display the total number of users.</p>
+</li>
+</ul>
+<p>If you choose to combine them, you can substitute the ``allusers'' in the
+second CDEF with the part after the equal sign from the first line:</p>
+<pre>
+   CDEF:wrongdata=users1,users2,users3,users4,+,+,+,UN,INF,UNKN,IF</pre>
+<p>If you do so, you won't be able to use these next GPRINTs:</p>
+<pre>
+   COMMENT:&quot;Total number of users seen&quot;
+   GPRINT:allusers:MAX:&quot;Maximum: %6.0lf&quot;

+<p>This demo demonstrates two ways to use infinity. It is a bit tricky
+to see what happens in the ``background'' CDEF.</p>
+<pre>
+   &quot;val4,POP,TIME,7200,%,3600,LE,INF,UNKN,IF&quot;</pre>
+<p>This RPN takes the value of ``val4'' as input and then immediately
+removes it from the stack using ``POP''. The stack is now empty but
+as a side effect we now know the time that this sample was taken.
+This time is put on the stack by the ``TIME'' function.</p>
+<p>``TIME,7200,%'' takes the modulo of time and 7'200 (which is two hours).
+The resulting value on the stack will be a number in the range from
+0 to 7199.</p>
+<p>For people who don't know the modulo function: it is the remainder
+after an integer division. If you divide 16 by 3, the answer would
+be 5 and the remainder would be 1. So, ``16,3,%'' returns 1.</p>
+<p>We have the result of ``TIME,7200,%'' on the stack, lets call this
+``a''. The start of the RPN has become ``a,3600,LE'' and this checks
+if ``a'' is less or equal than ``3600''. It is true half of the time.
+We now have to process the rest of the RPN and this is only a simple
+``IF'' function that returns either ``INF'' or ``UNKN'' depending on the
+time. This is returned to variable ``background''.</p>
+<p>The second CDEF has been discussed earlier in this document so we
+won't do that here.</p>
+<p>Now you can draw the different layers. Start with the background
+that is either unknown (nothing to see) or infinite (the whole
+positive part of the graph gets filled).</p>
+<p>Next you draw the data on top of this background, it will overlay
+the background. Suppose one of val1..val4 would be unknown, in that
+case you end up with only three bars stacked on top of each other.
+You don't want to see this because the data is only valid when all
+four variables are valid. This is why you use the second CDEF, it
+will overlay the data with an AREA so the data cannot be seen anymore.</p>
+<p>If your data can also have negative values you also need to overwrite
+the other half of your graph. This can be done in a relatively simple
+way: what you need is the ``wipeout'' variable and place a negative
+sign before it:  ``CDEF:wipeout2=wipeout,-1,*''</p>

+cdeftutorial - Alex van den Bogaerdt's CDEF tutorial
+
+=head1 DESCRIPTION
+
+Intention of this document: to provide some examples of the commonly
+used parts of RRDtool's CDEF language.
+
+If you think some important feature is not explained properly, and if
+adding it to this document would benefit most users, please do ask me
+to add it.  I will then try to provide an answer in the next release
+of this tutorial.  No feedback equals no changes! Additions to
+this document are also welcome.  -- Alex van den Bogaerdt
+E<lt>alex@ergens.op.het.netE<gt>
+
+=head2 Why this tutorial?
+
+One of the powerful parts of RRDtool is its ability to do all sorts
+of calculations on the data retrieved from its databases. However,
+RRDtool's many options and syntax make it difficult for the average
+user to understand. The manuals are good at explaining what these
+options do; however they do not (and should not) explain in detail
+why they are useful. As with my RRDtool tutorial: if you want a
+simple document in simple language you should read this tutorial.
+If you are happy with the official documentation, you may find this
+document too simple or even boring. If you do choose to read this
+tutorial, I also expect you to have read and fully understand my
+other tutorial.
+
+=head2 More reading
+
+If you have difficulties with the way I try to explain it please read
+Steve Rader's L<rpntutorial>. It may help you understand how this all works.
+
+=head1 What are CDEFs?
+
+When retrieving data from an RRD, you are using a "DEF" to work with
+that data. Think of it as a variable that changes over time (where
+time is the x-axis). The value of this variable is what is found in
+the database at that particular time and you can't do any
+modifications on it. This is what CDEFs are for: they takes values
+from DEFs and perform calculations on them.
+
+=head1 Syntax
+
+   DEF:var_name_1=some.rrd:ds_name:CF
+   CDEF:var_name_2=RPN_expression
+
+You first define "var_name_1" to be data collected from data source
+"ds_name" found in RRD "some.rrd" with consolidation function "CF".
+
+Assume the ifInOctets SNMP counter is saved in mrtg.rrd as the DS "in".
+Then the following DEF defines a variable for the average of that
+data source:
+
+   DEF:inbytes=mrtg.rrd:in:AVERAGE
+
+Say you want to display bits per second (instead of bytes per second
+as stored in the database.)  You have to define a calculation
+(hence "CDEF") on variable "inbytes" and use that variable (inbits)
+instead of the original:
+
+   CDEF:inbits=inbytes,8,*
+
+This tells RRDtool to multiply inbytes by eight to get inbits. I'll
+explain later how this works. In the graphing or printing functions,
+you can now use inbits where you would use inbytes otherwise.
+
+Note that the variable name used in the CDEF (inbits) must not be the
+same as the variable named in the DEF (inbytes)!
+
+=head1 RPN-expressions
+
+RPN is short-hand for Reverse Polish Notation. It works as follows.
+You put the variables or numbers on a stack. You also put operations
+(things-to-do) on the stack and this stack is then processed. The result
+will be placed on the stack. At the end, there should be exactly one
+number left: the outcome of the series of operations. If there is not
+exactly one number left, RRDtool will complain loudly.
+
+Above multiplication by eight will look like:
+
+=over 4
+
+=item 1.
+
+Start with an empty stack
+
+=item 2.
+
+Put the content of variable inbytes on the stack
+
+=item 3.
+
+Put the number eight on the stack
+
+=item 4.
+
+Put the operation multiply on the stack
+
+=item 5.
+
+Process the stack
+
+=item 6.
+
+Retrieve the value from the stack and put it in variable inbits
+
+=back
+
+We will now do an example with real numbers. Suppose the variable
+inbytes would have value 10, the stack would be:
+
+=over 4
+
+=item 1.
+
+||
+
+=item 2.
+
+|10|
+
+=item 3.
+
+|10|8|
+
+=item 4.
+
+|10|8|*|
+
+=item 5.
+
+|80|
+
+=item 6.
+
+||
+
+=back
+
+Processing the stack (step 5) will retrieve one value from the stack
+(from the right at step 4). This is the operation multiply and this
+takes two values off the stack as input. The result is put back on the
+stack (the value 80 in this case). For multiplication the order doesn't
+matter, but for other operations like subtraction and division it does.
+Generally speaking you have the following order:
+
+   y = A - B  -->  y=minus(A,B)  -->  CDEF:y=A,B,-
+
+This is not very intuitive (at least most people don't think so). For
+the function f(A,B) you reverse the position of "f", but you do not
+reverse the order of the variables.
+
+=head1 Converting your wishes to RPN
+
+First, get a clear picture of what you want to do. Break down the problem
+in smaller portions until they cannot be split anymore. Then it is rather
+simple to convert your ideas into RPN.
+
+Suppose you have several RRDs and would like to add up some counters in
+them. These could be, for instance, the counters for every WAN link you
+are monitoring.
+
+You have:
+
+   router1.rrd with link1in link2in
+   router2.rrd with link1in link2in
+   router3.rrd with link1in link2in
+
+Suppose you would like to add up all these counters, except for link2in
+inside router2.rrd. You need to do:
+
+(in this example, "router1.rrd:link1in" means the DS link1in inside the
+RRD router1.rrd)
+
+   router1.rrd:link1in
+   router1.rrd:link2in
+   router2.rrd:link1in
+   router3.rrd:link1in
+   router3.rrd:link2in
+   --------------------   +
+   (outcome of the sum)
+
+As a mathematical function, this could be written:
+
+C<add(router1.rrd:link1in , router1.rrd:link2in , router2.rrd:link1in , router3.rrd:link1in , router3.rrd:link2.in)>
+
+With RRDtool and RPN, first, define the inputs:
+
+   DEF:a=router1.rrd:link1in:AVERAGE
+   DEF:b=router1.rrd:link2in:AVERAGE
+   DEF:c=router2.rrd:link1in:AVERAGE
+   DEF:d=router3.rrd:link1in:AVERAGE
+   DEF:e=router3.rrd:link2in:AVERAGE
+
+Now, the mathematical function becomes: C<add(a,b,c,d,e)>
+
+In RPN, there's no operator that sums more than two values so you need
+to do several additions. You add a and b, add c to the result, add d
+to the result and add e to the result.
+
+   push a:         a     stack contains the value of a
+   push b and add: b,+   stack contains the result of a+b
+   push c and add: c,+   stack contains the result of a+b+c
+   push d and add: d,+   stack contains the result of a+b+c+d
+   push e and add: e,+   stack contains the result of a+b+c+d+e
+
+What was calculated here would be written down as:
+
+   ( ( ( (a+b) + c) + d) + e) >
+
+This is in RPN:  C<CDEF:result=a,b,+,c,+,d,+,e,+>
+
+This is correct but it can be made more clear to humans. It does
+not matter if you add a to b and then add c to the result or first
+add b to c and then add a to the result. This makes it possible to
+rewrite the RPN into C<CDEF:result=a,b,c,d,e,+,+,+,+> which is
+evaluated differently:
+
+   push value of variable a on the stack: a
+   push value of variable b on the stack: a b
+   push value of variable c on the stack: a b c
+   push value of variable d on the stack: a b c d
+   push value of variable e on the stack: a b c d e
+   push operator + on the stack:          a b c d e +
+   and process it:                        a b c P   (where P == d+e)
+   push operator + on the stack:          a b c P +
+   and process it:                        a b Q     (where Q == c+P)
+   push operator + on the stack:          a b Q +
+   and process it:                        a R       (where R == b+Q)
+   push operator + on the stack:          a R +
+   and process it:                        S         (where S == a+R)
+
+As you can see the RPN expression C<a,b,c,d,e,+,+,+,+,+> will evaluate in
+C<((((d+e)+c)+b)+a)> and it has the same outcome as C<a,b,+,c,+,d,+,e,+>.
+This is called the commutative law of addition,
+but you may forget this right away, as long as you remember what it
+means.
+
+Now look at an expression that contains a multiplication:
+
+First in normal math: C<let result = a+b*c>. In this case you can't
+choose the order yourself, you have to start with the multiplication
+and then add a to it. You may alter the position of b and c, you must
+not alter the position of a and b.
+
+You have to take this in consideration when converting this expression
+into RPN. Read it as: "Add the outcome of b*c to a" and then it is
+easy to write the RPN expression: C<result=a,b,c,*,+>
+Another expression that would return the same: C<result=b,c,*,a,+>
+
+In normal math, you may encounter something like "a*(b+c)" and this
+can also be converted into RPN. The parenthesis just tell you to first
+add b and c, and then multiply a with the result. Again, now it is
+easy to write it in RPN: C<result=a,b,c,+,*>. Note that this is very
+similar to one of the expressions in the previous paragraph, only the
+multiplication and the addition changed places.
+
+When you have problems with RPN or when RRDtool is complaining, it's
+usually a good thing to write down the stack on a piece of paper
+and see what happens. Have the manual ready and pretend to be RRDtool.
+Just do all the math by hand to see what happens, I'm sure this will
+solve most, if not all, problems you encounter.
+
+=head1 Some special numbers
+
+=head2 The unknown value
+
+Sometimes collecting your data will fail. This can be very common,
+especially when querying over busy links. RRDtool can be configured
+to allow for one (or even more) unknown value(s) and calculate the missing
+update. You can, for instance, query your device every minute. This is
+creating one so called PDP or primary data point per minute. If you
+defined your RRD to contain an RRA that stores 5-minute values, you need
+five of those PDPs to create one CDP (consolidated data point).
+These PDPs can become unknown in two cases:
+
+=over 4
+
+=item 1.
+
+The updates are too far apart. This is tuned using the "heartbeat" setting.
+
+=item 2.
+
+The update was set to unknown on purpose by inserting no value (using the
+template option) or by using "U" as the value to insert.
+
+=back
+
+When a CDP is calculated, another mechanism determines if this CDP is valid
+or not. If there are too many PDPs unknown, the CDP is unknown as well.
+This is determined by the xff factor. Please note that one unknown counter
+update can result in two unknown PDPs! If you only allow for one unknown
+PDP per CDP, this makes the CDP go unknown!
+
+Suppose the counter increments with one per second and you retrieve it
+every minute:
+
+   counter value    resulting rate
+   10'000
+   10'060            1; (10'060-10'000)/60 == 1
+   10'120            1; (10'120-10'060)/60 == 1
+   unknown           unknown; you don't know the last value
+   10'240            unknown; you don't know the previous value
+   10'300            1; (10'300-10'240)/60 == 1
+
+If the CDP was to be calculated from the last five updates, it would get
+two unknown PDPs and three known PDPs. If xff would have been set to 0.5
+which by the way is a commonly used factor, the CDP would have a known
+value of 1. If xff would have been set to 0.2 then the resulting CDP
+would be unknown.
+
+You have to decide the proper values for heartbeat, number of PDPs per
+CDP and the xff factor. As you can see from the previous text they define
+the behavior of your RRA.
+
+=head2 Working with unknown data in your database
+
+As you have read in the previous chapter, entries in an RRA can be
+set to the unknown value. If you do calculations with this type of
+value, the result has to be unknown too. This means that an expression
+such as C<result=a,b,+> will be unknown if either a or b is unknown.
+It would be wrong to just ignore the unknown value and return the value
+of the other parameter. By doing so, you would assume "unknown" means "zero"
+and this is not true.
+
+There has been a case where somebody was collecting data for over a year.
+A new piece of equipment was installed, a new RRD was created and the
+scripts were changed to add a counter from the old database and a counter
+from the new database. The result was disappointing, a large part of
+the statistics seemed to have vanished mysteriously ...
+They of course didn't, values from the old database (known values) were
+added to values from the new database (unknown values) and the result was
+unknown.
+
+In this case, it is fairly reasonable to use a CDEF that alters unknown
+data into zero. The counters of the device were unknown (after all, it
+wasn't installed yet!) but you know that the data rate through the device
+had to be zero (because of the same reason: it was not installed).
+
+There are some examples below that make this change.
+
+=head2 Infinity
+
+Infinite data is another form of a special number. It cannot be
+graphed because by definition you would never reach the infinite
+value. You can think of positive and negative infinity depending on
+the position relative to zero.
+
+RRDtool is capable of representing (-not- graphing!) infinity by stopping
+at its current maximum (for positive infinity) or minimum (for negative
+infinity) without knowing this maximum (minimum).
+
+Infinity in RRDtool is mostly used to draw an AREA without knowing its
+vertical dimensions. You can think of it as drawing an AREA with an
+infinite height and displaying only the part that is visible in the
+current graph. This is probably a good way to approximate infinity
+and it sure allows for some neat tricks. See below for examples.
+
+=head2 Working with unknown data and infinity
+
+Sometimes you would like to discard unknown data and pretend it is zero
+(or any other value for that matter) and sometimes you would like to
+pretend that known data is unknown (to discard known-to-be-wrong data).
+This is why CDEFs have support for unknown data. There are also examples
+available that show unknown data by using infinity.
+
+=head1 Some examples
+
+=head2 Example: using a recently created RRD
+
+You are keeping statistics on your router for over a year now. Recently
+you installed an extra router and you would like to show the combined
+throughput for these two devices.
+
+If you just add up the counters from router.rrd and router2.rrd, you
+will add known data (from router.rrd) to unknown data (from router2.rrd) for
+the bigger part of your stats. You could solve this in a few ways:
+
+=over 4
+
+=item *
+
+While creating the new database, fill it with zeros from the start to now.
+You have to make the database start at or before the least recent time in
+the other database.
+
+=item *
+
+Alternatively, you could use CDEF and alter unknown data to zero.
+
+=back
+
+Both methods have their pros and cons. The first method is troublesome and
+if you want to do that you have to figure it out yourself. It is not
+possible to create a database filled with zeros, you have to put them in
+manually. Implementing the second method is described next:
+
+What we want is: "if the value is unknown, replace it with zero". This
+could be written in pseudo-code as:  if (value is unknown) then (zero)
+else (value). When reading the L<rrdgraph> manual you notice the "UN"
+function that returns zero or one. You also notice the "IF" function
+that takes zero or one as input.
+
+First look at the "IF" function. It takes three values from the stack,
+the first value is the decision point, the second value is returned to
+the stack if the evaluation is "true" and if not, the third value is
+returned to the stack. We want the "UN" function to decide what happens
+so we combine those two functions in one CDEF.
+
+Lets write down the two possible paths for the "IF" function:
+
+   if true  return a
+   if false return b
+
+In RPN:  C<result=x,a,b,IF> where "x" is either true or false.
+
+Now we have to fill in "x", this should be the "(value is unknown)" part
+and this is in RPN:  C<result=value,UN>
+
+We now combine them: C<result=value,UN,a,b,IF> and when we fill in the
+appropriate things for "a" and "b" we're finished:
+
+C<CDEF:result=value,UN,0,value,IF>
+
+You may want to read Steve Rader's RPN guide if you have difficulties
+with the way I explained this last example.
+
+If you want to check this RPN expression, just mimic RRDtool behavior:
+
+   For any known value, the expression evaluates as follows:
+   CDEF:result=value,UN,0,value,IF  (value,UN) is not true so it becomes 0
+   CDEF:result=0,0,value,IF         "IF" will return the 3rd value
+   CDEF:result=value                The known value is returned
+
+   For the unknown value, this happens:
+   CDEF:result=value,UN,0,value,IF  (value,UN) is true so it becomes 1
+   CDEF:result=1,0,value,IF         "IF" sees 1 and returns the 2nd value
+   CDEF:result=0                    Zero is returned
+
+Of course, if you would like to see another value instead of zero, you
+can use that other value.
+
+Eventually, when all unknown data is removed from the RRD, you may want
+to remove this rule so that unknown data is properly displayed.
+
+=head2 Example: better handling of unknown data, by using time
+
+The above example has one drawback. If you do log unknown data in
+your database after installing your new equipment, it will also be
+translated into zero and therefore you won't see that there was a
+problem. This is not good and what you really want to do is:
+
+=over 4
+
+=item *
+
+If there is unknown data, look at the time that this sample was taken.
+
+=item *
+
+If the unknown value is before time xxx, make it zero.
+
+=item *
+
+If it is after time xxx, leave it as unknown data.
+
+=back
+
+This is doable: you can compare the time that the sample was taken
+to some known time. Assuming you started to monitor your device on
+Friday September 17, 1999, 00:35:57 MET DST. Translate this time in seconds
+since 1970-01-01 and it becomes 937'521'357. If you process unknown values
+that were received after this time, you want to leave them unknown and
+if they were "received" before this time, you want to translate them
+into zero (so you can effectively ignore them while adding them to your
+other routers counters).
+
+Translating Friday September 17, 1999, 00:35:57 MET DST into 937'521'357 can
+be done by, for instance, using gnu date:
+
+   date -d "19990917 00:35:57" +%s
+
+You could also dump the database and see where the data starts to be
+known. There are several other ways of doing this, just pick one.
+
+Now we have to create the magic that allows us to process unknown
+values different depending on the time that the sample was taken.
+This is a three step process:
+
+=over 4
+
+=item 1.
+
+If the timestamp of the value is after 937'521'357, leave it as is.
+
+=item 2.
+
+If the value is a known value, leave it as is.
+
+=item 3.
+
+Change the unknown value into zero.
+
+=back
+
+Lets look at part one:
+
+    if (true) return the original value
+
+We rewrite this:
+
+    if (true) return "a"
+    if (false) return "b"
+
+We need to calculate true or false from step 1. There is a function
+available that returns the timestamp for the current sample. It is
+called, how surprisingly, "TIME". This time has to be compared to
+a constant number, we need "GT". The output of "GT" is true or false
+and this is good input to "IF". We want "if (time > 937521357) then
+(return a) else (return b)".
+
+This process was already described thoroughly in the previous chapter
+so lets do it quick:
+
+   if (x) then a else b
+      where x represents "time>937521357"
+      where a represents the original value
+      where b represents the outcome of the previous example
+
+   time>937521357       --> TIME,937521357,GT
+
+   if (x) then a else b --> x,a,b,IF
+   substitute x         --> TIME,937521357,GT,a,b,IF
+   substitute a         --> TIME,937521357,GT,value,b,IF
+   substitute b         --> TIME,937521357,GT,value,value,UN,0,value,IF,IF
+
+We end up with:
+C<CDEF:result=TIME,937521357,GT,value,value,UN,0,value,IF,IF>
+
+This looks very complex, however, as you can see, it was not too hard to
+come up with.
+
+=head2 Example: Pretending weird data isn't there
+
+Suppose you have a problem that shows up as huge spikes in your graph.
+You know this happens and why, so you decide to work around the problem.
+Perhaps you're using your network to do a backup at night and by doing
+so you get almost 10mb/s while the rest of your network activity does
+not produce numbers higher than 100kb/s.
+
+There are two options:
+
+=over 4
+
+=item 1.
+
+If the number exceeds 100kb/s it is wrong and you want it masked out
+by changing it into unknown.
+
+=item 2.
+
+You don't want the graph to show more than 100kb/s.
+
+=back
+
+Pseudo code: if (number > 100) then unknown else number
+or
+Pseudo code: if (number > 100) then 100 else number.
+
+The second "problem" may also be solved by using the rigid option of
+RRDtool graph, however this has not the same result. In this example
+you can end up with a graph that does autoscaling. Also, if you use
+the numbers to display maxima they will be set to 100kb/s.
+
+We use "IF" and "GT" again. "if (x) then (y) else (z)" is written
+down as "CDEF:result=x,y,z,IF"; now fill in x, y and z.
+For x you fill in "number greater than 100kb/s" becoming
+"number,100000,GT" (kilo is 1'000 and b/s is what we measure!).
+The "z" part is "number" in both cases and the "y" part is either
+"UNKN" for unknown or "100000" for 100kb/s.
+
+The two CDEF expressions would be:
+
+    CDEF:result=number,100000,GT,UNKN,number,IF
+    CDEF:result=number,100000,GT,100000,number,IF
+
+=head2 Example: working on a certain time span
+
+If you want a graph that spans a few weeks, but would only want to
+see some routers' data for one week, you need to "hide" the rest of
+the time frame. Don't ask me when this would be useful, it's just
+here for the example :)
+
+We need to compare the time stamp to a begin date and an end date.
+Comparing isn't difficult:
+
+       TIME,begintime,GE
+       TIME,endtime,LE
+
+These two parts of the CDEF produce either 0 for false or 1 for true.
+We can now check if they are both 0 (or 1) using a few IF statements
+but, as Wataru Satoh pointed out, we can use the "*" or "+" functions
+as logical AND and logical OR.
+
+For "*", the result will be zero (false) if either one of the two
+operators is zero.  For "+", the result will only be false (0) when
+two false (0) operators will be added.  Warning: *any* number not
+equal to 0 will be considered "true". This means that, for instance,
+"-1,1,+" (which should be "true or true") will become FALSE ...
+In other words, use "+" only if you know for sure that you have positive
+numbers (or zero) only.
+
+Let's compile the complete CDEF:
+
+       DEF:ds0=router1.rrd:AVERAGE
+       CDEF:ds0modified=TIME,begintime,GE,TIME,endtime,LE,*,UNKN,ds0,IF
+
+This will return the value of ds0 if both comparisons return true. You
+could also do it the other way around:
+
+       DEF:ds0=router1.rrd:AVERAGE
+       CDEF:ds0modified=TIME,begintime,LT,TIME,endtime,GT,+,UNKN,ds0,IF
+
+This will return an UNKNOWN if either comparison returns true.
+
+=head2 Example: You suspect to have problems and want to see unknown data.
+
+Suppose you add up the number of active users on several terminal servers.
+If one of them doesn't give an answer (or an incorrect one) you get "NaN"
+in the database ("Not a Number") and NaN is evaluated as Unknown.
+
+In this case, you would like to be alerted to it and the sum of the
+remaining values is of no value to you.
+
+It would be something like:
+
+    DEF:users1=location1.rrd:onlineTS1:LAST
+    DEF:users2=location1.rrd:onlineTS2:LAST
+    DEF:users3=location2.rrd:onlineTS1:LAST
+    DEF:users4=location2.rrd:onlineTS2:LAST
+    CDEF:allusers=users1,users2,users3,users4,+,+,+
+
+If you now plot allusers, unknown data in one of users1..users4 will
+show up as a gap in your graph. You want to modify this to show a
+bright red line, not a gap.
+
+Define an extra CDEF that is unknown if all is okay and is infinite if
+there is an unknown value:
+
+    CDEF:wrongdata=allusers,UN,INF,UNKN,IF
+
+"allusers,UN" will evaluate to either true or false, it is the (x) part
+of the "IF" function and it checks if allusers is unknown.
+The (y) part of the "IF" function is set to "INF" (which means infinity)
+and the (z) part of the function returns "UNKN".
+
+The logic is: if (allusers == unknown) then return INF else return UNKN.
+
+You can now use AREA to display this "wrongdata" in bright red. If it
+is unknown (because allusers is known) then the red AREA won't show up.
+If the value is INF (because allusers is unknown) then the red AREA will
+be filled in on the graph at that particular time.
+
+   AREA:allusers#0000FF:combined user count
+   AREA:wrongdata#FF0000:unknown data
+
+=head2 Same example useful with STACKed data:
+
+If you use stack in the previous example (as I would do) then you don't
+add up the values. Therefore, there is no relationship between the
+four values and you don't get a single value to test.
+Suppose users3 would be unknown at one point in time: users1 is plotted,
+users2 is stacked on top of users1, users3 is unknown and therefore
+nothing happens, users4 is stacked on top of users2.
+Add the extra CDEFs anyway and use them to overlay the "normal" graph:
+
+   DEF:users1=location1.rrd:onlineTS1:LAST
+   DEF:users2=location1.rrd:onlineTS2:LAST
+   DEF:users3=location2.rrd:onlineTS1:LAST
+   DEF:users4=location2.rrd:onlineTS2:LAST
+   CDEF:allusers=users1,users2,users3,users4,+,+,+
+   CDEF:wrongdata=allusers,UN,INF,UNKN,IF
+   AREA:users1#0000FF:users at ts1
+   STACK:users2#00FF00:users at ts2
+   STACK:users3#00FFFF:users at ts3
+   STACK:users4#FFFF00:users at ts4
+   AREA:wrongdata#FF0000:unknown data
+
+If there is unknown data in one of users1..users4, the "wrongdata" AREA
+will be drawn and because it starts at the X-axis and has infinite height
+it will effectively overwrite the STACKed parts.
+
+You could combine the two CDEF lines into one (we don't use "allusers")
+if you like.  But there are good reasons for writing two CDEFS:
+
+=over 4
+
+=item *
+
+It improves the readability of the script.
+
+=item *
+
+It can be used inside GPRINT to display the total number of users.
+
+=back
+
+If you choose to combine them, you can substitute the "allusers" in the
+second CDEF with the part after the equal sign from the first line:
+
+   CDEF:wrongdata=users1,users2,users3,users4,+,+,+,UN,INF,UNKN,IF
+
+If you do so, you won't be able to use these next GPRINTs:
+
+   COMMENT:"Total number of users seen"
+   GPRINT:allusers:MAX:"Maximum: %6.0lf"
+   GPRINT:allusers:MIN:"Minimum: %6.0lf"
+   GPRINT:allusers:AVERAGE:"Average: %6.0lf"
+   GPRINT:allusers:LAST:"Current: %6.0lf\n"

+
+To convert Celsius into Fahrenheit use the formula
+F=9/5*C+32

+      LINE2:cel#00a000:"D. Celsius" \
+      LINE2:far#ff0000:"D. Fahrenheit\c"
+
+This example gets the DS called "exhaust" from database "demo.rrd"
+and puts the values in variable "cel". The CDEF used is evaluated
+as follows:
+
+   CDEF:far=9,5,/,cel,*,32,+
+   1. push 9, push 5
+   2. push function "divide" and process it
+      the stack now contains 9/5
+   3. push variable "cel"
+   4. push function "multiply" and process it
+      the stack now contains 9/5*cel
+   5. push 32
+   6. push function "plus" and process it
+      the stack contains now the temperature in Fahrenheit

+      AREA:agginput#00cc00:Input Aggregate \
+      LINE1:aggoutput#0000FF:Output Aggregate
+
+These two CDEFs are built from several functions. It helps to split
+them when viewing what they do. Starting with the first CDEF we would
+get:
+
+ idat1,UN --> a
+ 0        --> b
+ idat1    --> c
+ if (a) then (b) else (c)
+
+The result is therefore "0" if it is true that "idat1" equals "UN".
+If not, the original value of "idat1" is put back on the stack.
+Lets call this answer "d". The process is repeated for the next
+five items on the stack, it is done the same and will return answer
+"h". The resulting stack is therefore "d,h".
+The expression has been simplified to "d,h,+,8,*" and it will now be
+easy to see that we add "d" and "h", and multiply the result with eight.
+
+The end result is that we have added "idat1" and "idat2" and in the
+process we effectively ignored unknown values. The result is multiplied
+by eight, most likely to convert bytes/s to bits/s.

+
+This demo demonstrates two ways to use infinity. It is a bit tricky
+to see what happens in the "background" CDEF.
+
+   "val4,POP,TIME,7200,%,3600,LE,INF,UNKN,IF"
+
+This RPN takes the value of "val4" as input and then immediately
+removes it from the stack using "POP". The stack is now empty but
+as a side effect we now know the time that this sample was taken.
+This time is put on the stack by the "TIME" function.
+
+"TIME,7200,%" takes the modulo of time and 7'200 (which is two hours).
+The resulting value on the stack will be a number in the range from
+0 to 7199.
+
+For people who don't know the modulo function: it is the remainder
+after an integer division. If you divide 16 by 3, the answer would
+be 5 and the remainder would be 1. So, "16,3,%" returns 1.
+
+We have the result of "TIME,7200,%" on the stack, lets call this
+"a". The start of the RPN has become "a,3600,LE" and this checks
+if "a" is less or equal than "3600". It is true half of the time.
+We now have to process the rest of the RPN and this is only a simple
+"IF" function that returns either "INF" or "UNKN" depending on the
+time. This is returned to variable "background".
+
+The second CDEF has been discussed earlier in this document so we
+won't do that here.
+
+Now you can draw the different layers. Start with the background
+that is either unknown (nothing to see) or infinite (the whole
+positive part of the graph gets filled).
+
+Next you draw the data on top of this background, it will overlay
+the background. Suppose one of val1..val4 would be unknown, in that
+case you end up with only three bars stacked on top of each other.
+You don't want to see this because the data is only valid when all
+four variables are valid. This is why you use the second CDEF, it
+will overlay the data with an AREA so the data cannot be seen anymore.
+
+If your data can also have negative values you also need to overwrite
+the other half of your graph. This can be done in a relatively simple
+way: what you need is the "wipeout" variable and place a negative
+sign before it:  "CDEF:wipeout2=wipeout,-1,*"
+
+=head2 Filtering data
+
+You may do some complex data filtering:
+
+  MEDIAN FILTER: filters shot noise
+
+    DEF:var=database.rrd:traffic:AVERAGE
+    CDEF:prev1=PREV(var)
+    CDEF:prev2=PREV(prev1)
+    CDEF:prev3=PREV(prev2)
+    CDEF:median=prev1,prev2,prev3,+,+,3,/
+    LINE3:median#000077:filtered
+    LINE1:prev2#007700:'raw data'
+
+
+  DERIVATE:
+
+    DEF:var=database.rrd:traffic:AVERAGE
+    CDEF:prev1=PREV(var)
+    CDEF:time=TIME
+    CDEF:prevtime=PREV(time)
+    CDEF:derivate=var,prev1,-,time,prevtime,-,/
+    LINE3:derivate#000077:derivate
+    LINE1:var#007700:'raw data'

+
+       One of the powerful parts of RRDtool is its ability to do all sorts of
+       calculations on the data retrieved from its databases. However, RRD-
+       tool's many options and syntax make it difficult for the average user
+       to understand. The manuals are good at explaining what these options
+       do; however they do not (and should not) explain in detail why they are
+       useful. As with my RRDtool tutorial: if you want a simple document in
+       simple language you should read this tutorial.  If you are happy with
+       the official documentation, you may find this document too simple or
+       even boring. If you do choose to read this tutorial, I also expect you
+       to have read and fully understand my other tutorial.

+       Steve Rader's rpntutorial. It may help you understand how this all
+       works.
+
+W\bWh\bha\bat\bt a\bar\bre\be C\bCD\bDE\bEF\bFs\bs?\b?
+       When retrieving data from an RRD, you are using a "DEF" to work with
+       that data. Think of it as a variable that changes over time (where time
+       is the x-axis). The value of this variable is what is found in the
+       database at that particular time and you can't do any modifications on
+       it. This is what CDEFs are for: they takes values from DEFs and perform
+       calculations on them.
+
+S\bSy\byn\bnt\bta\bax\bx
+          DEF:var_name_1=some.rrd:ds_name:CF
+          CDEF:var_name_2=RPN_expression
+
+       You first define "var_name_1" to be data collected from data source
+       "ds_name" found in RRD "some.rrd" with consolidation function "CF".
+
+       Assume the ifInOctets SNMP counter is saved in mrtg.rrd as the DS "in".
+       Then the following DEF defines a variable for the average of that data
+       source:
+
+          DEF:inbytes=mrtg.rrd:in:AVERAGE
+
+       Say you want to display bits per second (instead of bytes per second as
+       stored in the database.)  You have to define a calculation (hence
+       "CDEF") on variable "inbytes" and use that variable (inbits) instead of
+       the original:
+
+          CDEF:inbits=inbytes,8,*
+
+       This tells RRDtool to multiply inbytes by eight to get inbits. I'll
+       explain later how this works. In the graphing or printing functions,
+       you can now use inbits where you would use inbytes otherwise.
+
+       Note that the variable name used in the CDEF (inbits) must not be the
+       same as the variable named in the DEF (inbytes)!
+
+R\bRP\bPN\bN-\b-e\bex\bxp\bpr\bre\bes\bss\bsi\bio\bon\bns\bs
+       RPN is short-hand for Reverse Polish Notation. It works as follows.
+       You put the variables or numbers on a stack. You also put operations
+       (things-to-do) on the stack and this stack is then processed. The
+       result will be placed on the stack. At the end, there should be exactly
+       one number left: the outcome of the series of operations. If there is
+       not exactly one number left, RRDtool will complain loudly.
+
+       Above multiplication by eight will look like:
+
+       1.  Start with an empty stack
+
+       2.  Put the content of variable inbytes on the stack
+
+       3.  Put the number eight on the stack
+
+       4.  Put the operation multiply on the stack
+
+       5.  Process the stack
+
+       6.  Retrieve the value from the stack and put it in variable inbits
+
+       We will now do an example with real numbers. Suppose the variable
+       inbytes would have value 10, the stack would be:
+
+       1.  ||
+
+       2.  |10|
+
+       3.  |10|8|
+
+       4.  |10|8|*|
+
+       5.  |80|
+
+       6.  ||
+
+       Processing the stack (step 5) will retrieve one value from the stack
+       (from the right at step 4). This is the operation multiply and this
+       takes two values off the stack as input. The result is put back on the
+       stack (the value 80 in this case). For multiplication the order doesn't
+       matter, but for other operations like subtraction and division it does.
+       Generally speaking you have the following order:
+
+          y = A - B  -->  y=minus(A,B)  -->  CDEF:y=A,B,-
+
+       This is not very intuitive (at least most people don't think so). For
+       the function f(A,B) you reverse the position of "f", but you do not
+       reverse the order of the variables.
+
+C\bCo\bon\bnv\bve\ber\brt\bti\bin\bng\bg y\byo\bou\bur\br w\bwi\bis\bsh\bhe\bes\bs t\bto\bo R\bRP\bPN\bN
+       First, get a clear picture of what you want to do. Break down the prob-
+       lem in smaller portions until they cannot be split anymore. Then it is
+       rather simple to convert your ideas into RPN.
+
+       Suppose you have several RRDs and would like to add up some counters in
+       them. These could be, for instance, the counters for every WAN link you
+       are monitoring.
+
+       You have:
+
+          router1.rrd with link1in link2in
+          router2.rrd with link1in link2in
+          router3.rrd with link1in link2in
+
+       Suppose you would like to add up all these counters, except for link2in
+       inside router2.rrd. You need to do:
+
+       (in this example, "router1.rrd:link1in" means the DS link1in inside the
+       RRD router1.rrd)
+
+          router1.rrd:link1in
+          router1.rrd:link2in
+          router2.rrd:link1in
+          router3.rrd:link1in
+          router3.rrd:link2in
+          --------------------   +
+          (outcome of the sum)
+
+       As a mathematical function, this could be written:
+
+       "add(router1.rrd:link1in , router1.rrd:link2in , router2.rrd:link1in ,
+       router3.rrd:link1in , router3.rrd:link2.in)"
+
+       With RRDtool and RPN, first, define the inputs:
+
+          DEF:a=router1.rrd:link1in:AVERAGE
+          DEF:b=router1.rrd:link2in:AVERAGE
+          DEF:c=router2.rrd:link1in:AVERAGE
+          DEF:d=router3.rrd:link1in:AVERAGE
+          DEF:e=router3.rrd:link2in:AVERAGE
+
+       Now, the mathematical function becomes: "add(a,b,c,d,e)"
+
+       In RPN, there's no operator that sums more than two values so you need
+       to do several additions. You add a and b, add c to the result, add d to
+       the result and add e to the result.
+
+          push a:         a     stack contains the value of a
+          push b and add: b,+   stack contains the result of a+b
+          push c and add: c,+   stack contains the result of a+b+c
+          push d and add: d,+   stack contains the result of a+b+c+d
+          push e and add: e,+   stack contains the result of a+b+c+d+e
+
+       What was calculated here would be written down as:
+
+          ( ( ( (a+b) + c) + d) + e) >
+
+       This is in RPN:  "CDEF:result=a,b,+,c,+,d,+,e,+"
+
+       This is correct but it can be made more clear to humans. It does not
+       matter if you add a to b and then add c to the result or first add b to
+       c and then add a to the result. This makes it possible to rewrite the
+       RPN into "CDEF:result=a,b,c,d,e,+,+,+,+" which is evaluated differ-
+       ently:
+
+          push value of variable a on the stack: a
+          push value of variable b on the stack: a b
+          push value of variable c on the stack: a b c
+          push value of variable d on the stack: a b c d
+          push value of variable e on the stack: a b c d e
+          push operator + on the stack:          a b c d e +
+          and process it:                        a b c P   (where P == d+e)
+          push operator + on the stack:          a b c P +
+          and process it:                        a b Q     (where Q == c+P)
+          push operator + on the stack:          a b Q +
+          and process it:                        a R       (where R == b+Q)
+          push operator + on the stack:          a R +
+          and process it:                        S         (where S == a+R)
+
+       As you can see the RPN expression "a,b,c,d,e,+,+,+,+,+" will evaluate
+       in "((((d+e)+c)+b)+a)" and it has the same outcome as
+       "a,b,+,c,+,d,+,e,+".  This is called the commutative law of addition,
+       but you may forget this right away, as long as you remember what it
+       means.
+
+       Now look at an expression that contains a multiplication:
+
+       First in normal math: "let result = a+b*c". In this case you can't
+       choose the order yourself, you have to start with the multiplication
+       and then add a to it. You may alter the position of b and c, you must
+       not alter the position of a and b.
+
+       You have to take this in consideration when converting this expression
+       into RPN. Read it as: "Add the outcome of b*c to a" and then it is easy
+       to write the RPN expression: "result=a,b,c,*,+" Another expression that
+       would return the same: "result=b,c,*,a,+"
+
+       In normal math, you may encounter something like "a*(b+c)" and this can
+       also be converted into RPN. The parenthesis just tell you to first add
+       b and c, and then multiply a with the result. Again, now it is easy to
+       write it in RPN: "result=a,b,c,+,*". Note that this is very similar to
+       one of the expressions in the previous paragraph, only the multiplica-
+       tion and the addition changed places.
+
+       When you have problems with RPN or when RRDtool is complaining, it's
+       usually a good thing to write down the stack on a piece of paper and
+       see what happens. Have the manual ready and pretend to be RRDtool.
+       Just do all the math by hand to see what happens, I'm sure this will
+       solve most, if not all, problems you encounter.

+
+       Sometimes collecting your data will fail. This can be very common,
+       especially when querying over busy links. RRDtool can be configured to
+       allow for one (or even more) unknown value(s) and calculate the missing
+       update. You can, for instance, query your device every minute. This is
+       creating one so called PDP or primary data point per minute. If you
+       defined your RRD to contain an RRA that stores 5-minute values, you
+       need five of those PDPs to create one CDP (consolidated data point).
+       These PDPs can become unknown in two cases:
+
+       1.  The updates are too far apart. This is tuned using the "heartbeat"
+           setting.
+
+       2.  The update was set to unknown on purpose by inserting no value
+           (using the template option) or by using "U" as the value to insert.
+
+       When a CDP is calculated, another mechanism determines if this CDP is
+       valid or not. If there are too many PDPs unknown, the CDP is unknown as
+       well.  This is determined by the xff factor. Please note that one
+       unknown counter update can result in two unknown PDPs! If you only
+       allow for one unknown PDP per CDP, this makes the CDP go unknown!
+
+       Suppose the counter increments with one per second and you retrieve it
+       every minute:
+
+          counter value    resulting rate
+          10'000
+          10'060            1; (10'060-10'000)/60 == 1
+          10'120            1; (10'120-10'060)/60 == 1
+          unknown           unknown; you don't know the last value
+          10'240            unknown; you don't know the previous value
+          10'300            1; (10'300-10'240)/60 == 1
+
+       If the CDP was to be calculated from the last five updates, it would
+       get two unknown PDPs and three known PDPs. If xff would have been set
+       to 0.5 which by the way is a commonly used factor, the CDP would have a
+       known value of 1. If xff would have been set to 0.2 then the resulting
+       CDP would be unknown.
+
+       You have to decide the proper values for heartbeat, number of PDPs per
+       CDP and the xff factor. As you can see from the previous text they
+       define the behavior of your RRA.

+
+       As you have read in the previous chapter, entries in an RRA can be set
+       to the unknown value. If you do calculations with this type of value,
+       the result has to be unknown too. This means that an expression such as
+       "result=a,b,+" will be unknown if either a or b is unknown.  It would
+       be wrong to just ignore the unknown value and return the value of the
+       other parameter. By doing so, you would assume "unknown" means "zero"
+       and this is not true.
+
+       There has been a case where somebody was collecting data for over a
+       year.  A new piece of equipment was installed, a new RRD was created
+       and the scripts were changed to add a counter from the old database and
+       a counter from the new database. The result was disappointing, a large
+       part of the statistics seemed to have vanished mysteriously ...  They
+       of course didn't, values from the old database (known values) were
+       added to values from the new database (unknown values) and the result
+       was unknown.
+
+       In this case, it is fairly reasonable to use a CDEF that alters unknown
+       data into zero. The counters of the device were unknown (after all, it
+       wasn't installed yet!) but you know that the data rate through the
+       device had to be zero (because of the same reason: it was not
+       installed).
+
+       There are some examples below that make this change.

+
+       Infinite data is another form of a special number. It cannot be graphed
+       because by definition you would never reach the infinite value. You can
+       think of positive and negative infinity depending on the position rela-
+       tive to zero.
+
+       RRDtool is capable of representing (-not- graphing!) infinity by stop-
+       ping at its current maximum (for positive infinity) or minimum (for
+       negative infinity) without knowing this maximum (minimum).
+
+       Infinity in RRDtool is mostly used to draw an AREA without knowing its
+       vertical dimensions. You can think of it as drawing an AREA with an
+       infinite height and displaying only the part that is visible in the
+       current graph. This is probably a good way to approximate infinity and

+       Sometimes you would like to discard unknown data and pretend it is zero
+       (or any other value for that matter) and sometimes you would like to
+       pretend that known data is unknown (to discard known-to-be-wrong data).
+       This is why CDEFs have support for unknown data. There are also exam-
+       ples available that show unknown data by using infinity.

+
+       You are keeping statistics on your router for over a year now. Recently
+       you installed an extra router and you would like to show the combined
+       throughput for these two devices.
+
+       If you just add up the counters from router.rrd and router2.rrd, you
+       will add known data (from router.rrd) to unknown data (from
+       router2.rrd) for the bigger part of your stats. You could solve this in
+       a few ways:
+
+       ·   While creating the new database, fill it with zeros from the start
+           to now.  You have to make the database start at or before the least
+           recent time in the other database.
+
+       ·   Alternatively, you could use CDEF and alter unknown data to zero.
+
+       Both methods have their pros and cons. The first method is troublesome
+       and if you want to do that you have to figure it out yourself. It is
+       not possible to create a database filled with zeros, you have to put
+       them in manually. Implementing the second method is described next:
+
+       What we want is: "if the value is unknown, replace it with zero". This
+       could be written in pseudo-code as:  if (value is unknown) then (zero)
+       else (value). When reading the rrdgraph manual you notice the "UN"
+       function that returns zero or one. You also notice the "IF" function
+       that takes zero or one as input.
+
+       First look at the "IF" function. It takes three values from the stack,
+       the first value is the decision point, the second value is returned to
+       the stack if the evaluation is "true" and if not, the third value is
+       returned to the stack. We want the "UN" function to decide what happens
+       so we combine those two functions in one CDEF.
+
+       Lets write down the two possible paths for the "IF" function:
+
+          if true  return a
+          if false return b
+
+       In RPN:  "result=x,a,b,IF" where "x" is either true or false.
+
+       Now we have to fill in "x", this should be the "(value is unknown)"
+       part and this is in RPN:  "result=value,UN"
+
+       We now combine them: "result=value,UN,a,b,IF" and when we fill in the
+       appropriate things for "a" and "b" we're finished:
+
+       "CDEF:result=value,UN,0,value,IF"
+
+       You may want to read Steve Rader's RPN guide if you have difficulties
+       with the way I explained this last example.
+
+       If you want to check this RPN expression, just mimic RRDtool behavior:
+
+          For any known value, the expression evaluates as follows:
+          CDEF:result=value,UN,0,value,IF  (value,UN) is not true so it becomes 0
+          CDEF:result=0,0,value,IF         "IF" will return the 3rd value
+          CDEF:result=value                The known value is returned
+
+          For the unknown value, this happens:
+          CDEF:result=value,UN,0,value,IF  (value,UN) is true so it becomes 1
+          CDEF:result=1,0,value,IF         "IF" sees 1 and returns the 2nd value
+          CDEF:result=0                    Zero is returned
+
+       Of course, if you would like to see another value instead of zero, you
+       can use that other value.
+
+       Eventually, when all unknown data is removed from the RRD, you may want
+       to remove this rule so that unknown data is properly displayed.
+
+       E\bEx\bxa\bam\bmp\bpl\ble\be:\b: b\bbe\bet\btt\bte\ber\br h\bha\ban\bnd\bdl\bli\bin\bng\bg o\bof\bf u\bun\bnk\bkn\bno\bow\bwn\bn d\bda\bat\bta\ba,\b, b\bby\by u\bus\bsi\bin\bng\bg t\bti\bim\bme\be
+
+       The above example has one drawback. If you do log unknown data in your
+       database after installing your new equipment, it will also be trans-
+       lated into zero and therefore you won't see that there was a problem.
+       This is not good and what you really want to do is:
+
+       ·   If there is unknown data, look at the time that this sample was
+           taken.
+
+       ·   If the unknown value is before time xxx, make it zero.
+
+       ·   If it is after time xxx, leave it as unknown data.
+
+       This is doable: you can compare the time that the sample was taken to
+       some known time. Assuming you started to monitor your device on Friday
+       September 17, 1999, 00:35:57 MET DST. Translate this time in seconds
+       since 1970-01-01 and it becomes 937'521'357. If you process unknown
+       values that were received after this time, you want to leave them
+       unknown and if they were "received" before this time, you want to
+       translate them into zero (so you can effectively ignore them while
+       adding them to your other routers counters).
+
+       Translating Friday September 17, 1999, 00:35:57 MET DST into
+       937'521'357 can be done by, for instance, using gnu date:
+
+          date -d "19990917 00:35:57" +%s
+
+       You could also dump the database and see where the data starts to be
+       known. There are several other ways of doing this, just pick one.
+
+       Now we have to create the magic that allows us to process unknown val-
+       ues different depending on the time that the sample was taken.  This is
+       a three step process:
+
+       1.  If the timestamp of the value is after 937'521'357, leave it as is.
+
+       2.  If the value is a known value, leave it as is.
+
+       3.  Change the unknown value into zero.
+
+       Lets look at part one:
+
+           if (true) return the original value
+
+       We rewrite this:
+
+           if (true) return "a"
+           if (false) return "b"
+
+       We need to calculate true or false from step 1. There is a function
+       available that returns the timestamp for the current sample. It is
+       called, how surprisingly, "TIME". This time has to be compared to a
+       constant number, we need "GT". The output of "GT" is true or false and
+       this is good input to "IF". We want "if (time > 937521357) then (return
+       a) else (return b)".
+
+       This process was already described thoroughly in the previous chapter
+       so lets do it quick:
+
+          if (x) then a else b
+             where x represents "time>937521357"
+             where a represents the original value
+             where b represents the outcome of the previous example
+
+          time>937521357       --> TIME,937521357,GT
+
+          if (x) then a else b --> x,a,b,IF
+          substitute x         --> TIME,937521357,GT,a,b,IF
+          substitute a         --> TIME,937521357,GT,value,b,IF
+          substitute b         --> TIME,937521357,GT,value,value,UN,0,value,IF,IF
+
+       We end up with:
+       "CDEF:result=TIME,937521357,GT,value,value,UN,0,value,IF,IF"
+
+       This looks very complex, however, as you can see, it was not too hard
+       to come up with.
+
+       E\bEx\bxa\bam\bmp\bpl\ble\be:\b: P\bPr\bre\bet\bte\ben\bnd\bdi\bin\bng\bg w\bwe\bei\bir\brd\bd d\bda\bat\bta\ba i\bis\bsn\bn'\b't\bt t\bth\bhe\ber\bre\be
+
+       Suppose you have a problem that shows up as huge spikes in your graph.
+       You know this happens and why, so you decide to work around the prob-
+       lem.  Perhaps you're using your network to do a backup at night and by
+       doing so you get almost 10mb/s while the rest of your network activity
+       does not produce numbers higher than 100kb/s.
+
+       There are two options:
+
+       1.  If the number exceeds 100kb/s it is wrong and you want it masked
+           out by changing it into unknown.
+
+       2.  You don't want the graph to show more than 100kb/s.
+
+       Pseudo code: if (number > 100) then unknown else number or Pseudo code:
+       if (number > 100) then 100 else number.
+
+       The second "problem" may also be solved by using the rigid option of
+       RRDtool graph, however this has not the same result. In this example
+       you can end up with a graph that does autoscaling. Also, if you use the
+       numbers to display maxima they will be set to 100kb/s.
+
+       We use "IF" and "GT" again. "if (x) then (y) else (z)" is written down
+       as "CDEF:result=x,y,z,IF"; now fill in x, y and z.  For x you fill in
+       "number greater than 100kb/s" becoming "number,100000,GT" (kilo is
+       1'000 and b/s is what we measure!).  The "z" part is "number" in both
+       cases and the "y" part is either "UNKN" for unknown or "100000" for
+       100kb/s.
+
+       The two CDEF expressions would be:
+
+           CDEF:result=number,100000,GT,UNKN,number,IF
+           CDEF:result=number,100000,GT,100000,number,IF

+
+       If you want a graph that spans a few weeks, but would only want to see
+       some routers' data for one week, you need to "hide" the rest of the
+       time frame. Don't ask me when this would be useful, it's just here for
+       the example :)
+
+       We need to compare the time stamp to a begin date and an end date.
+       Comparing isn't difficult:
+
+               TIME,begintime,GE
+               TIME,endtime,LE
+
+       These two parts of the CDEF produce either 0 for false or 1 for true.
+       We can now check if they are both 0 (or 1) using a few IF statements
+       but, as Wataru Satoh pointed out, we can use the "*" or "+" functions
+       as logical AND and logical OR.
+
+       For "*", the result will be zero (false) if either one of the two oper-
+       ators is zero.  For "+", the result will only be false (0) when two
+       false (0) operators will be added.  Warning: *any* number not equal to
+       0 will be considered "true". This means that, for instance, "-1,1,+"
+       (which should be "true or true") will become FALSE ...  In other words,
+       use "+" only if you know for sure that you have positive numbers (or
+       zero) only.
+
+       Let's compile the complete CDEF:
+
+               DEF:ds0=router1.rrd:AVERAGE
+               CDEF:ds0modified=TIME,begintime,GE,TIME,endtime,LE,*,UNKN,ds0,IF
+
+       This will return the value of ds0 if both comparisons return true. You
+       could also do it the other way around:
+
+               DEF:ds0=router1.rrd:AVERAGE
+               CDEF:ds0modified=TIME,begintime,LT,TIME,endtime,GT,+,UNKN,ds0,IF
+
+       This will return an UNKNOWN if either comparison returns true.
+
+       E\bEx\bxa\bam\bmp\bpl\ble\be:\b: Y\bYo\bou\bu s\bsu\bus\bsp\bpe\bec\bct\bt t\bto\bo h\bha\bav\bve\be p\bpr\bro\bob\bbl\ble\bem\bms\bs a\ban\bnd\bd w\bwa\ban\bnt\bt t\bto\bo s\bse\bee\be u\bun\bnk\bkn\bno\bow\bwn\bn d\bda\bat\bta\ba.\b.
+
+       Suppose you add up the number of active users on several terminal
+       servers.  If one of them doesn't give an answer (or an incorrect one)
+       you get "NaN" in the database ("Not a Number") and NaN is evaluated as
+       Unknown.
+
+       In this case, you would like to be alerted to it and the sum of the
+       remaining values is of no value to you.
+
+       It would be something like:
+
+           DEF:users1=location1.rrd:onlineTS1:LAST
+           DEF:users2=location1.rrd:onlineTS2:LAST
+           DEF:users3=location2.rrd:onlineTS1:LAST
+           DEF:users4=location2.rrd:onlineTS2:LAST
+           CDEF:allusers=users1,users2,users3,users4,+,+,+
+
+       If you now plot allusers, unknown data in one of users1..users4 will
+       show up as a gap in your graph. You want to modify this to show a
+       bright red line, not a gap.
+
+       Define an extra CDEF that is unknown if all is okay and is infinite if
+       there is an unknown value:
+
+           CDEF:wrongdata=allusers,UN,INF,UNKN,IF
+
+       "allusers,UN" will evaluate to either true or false, it is the (x) part
+       of the "IF" function and it checks if allusers is unknown.  The (y)
+       part of the "IF" function is set to "INF" (which means infinity) and
+       the (z) part of the function returns "UNKN".
+
+       The logic is: if (allusers == unknown) then return INF else return
+       UNKN.
+
+       You can now use AREA to display this "wrongdata" in bright red. If it
+       is unknown (because allusers is known) then the red AREA won't show up.
+       If the value is INF (because allusers is unknown) then the red AREA
+       will be filled in on the graph at that particular time.
+
+          AREA:allusers#0000FF:combined user count
+          AREA:wrongdata#FF0000:unknown data

+
+       If you use stack in the previous example (as I would do) then you don't
+       add up the values. Therefore, there is no relationship between the four
+       values and you don't get a single value to test.  Suppose users3 would
+       be unknown at one point in time: users1 is plotted, users2 is stacked
+       on top of users1, users3 is unknown and therefore nothing happens,
+       users4 is stacked on top of users2.  Add the extra CDEFs anyway and use
+       them to overlay the "normal" graph:
+
+          DEF:users1=location1.rrd:onlineTS1:LAST
+          DEF:users2=location1.rrd:onlineTS2:LAST
+          DEF:users3=location2.rrd:onlineTS1:LAST
+          DEF:users4=location2.rrd:onlineTS2:LAST
+          CDEF:allusers=users1,users2,users3,users4,+,+,+
+          CDEF:wrongdata=allusers,UN,INF,UNKN,IF
+          AREA:users1#0000FF:users at ts1
+          STACK:users2#00FF00:users at ts2
+          STACK:users3#00FFFF:users at ts3
+          STACK:users4#FFFF00:users at ts4
+          AREA:wrongdata#FF0000:unknown data
+
+       If there is unknown data in one of users1..users4, the "wrongdata" AREA
+       will be drawn and because it starts at the X-axis and has infinite
+       height it will effectively overwrite the STACKed parts.
+
+       You could combine the two CDEF lines into one (we don't use "allusers")
+       if you like.  But there are good reasons for writing two CDEFS:
+
+       ·   It improves the readability of the script.
+
+       ·   It can be used inside GPRINT to display the total number of users.
+
+       If you choose to combine them, you can substitute the "allusers" in the
+       second CDEF with the part after the equal sign from the first line:
+
+          CDEF:wrongdata=users1,users2,users3,users4,+,+,+,UN,INF,UNKN,IF
+
+       If you do so, you won't be able to use these next GPRINTs:
+
+          COMMENT:"Total number of users seen"
+          GPRINT:allusers:MAX:"Maximum: %6.0lf"
+          GPRINT:allusers:MIN:"Minimum: %6.0lf"
+          GPRINT:allusers:AVERAGE:"Average: %6.0lf"
+          GPRINT:allusers:LAST:"Current: %6.0lf\n"

+
+       These two CDEFs are built from several functions. It helps to split
+       them when viewing what they do. Starting with the first CDEF we would
+       get:
+
+        idat1,UN --> a
+        0        --> b
+        idat1    --> c
+        if (a) then (b) else (c)
+
+       The result is therefore "0" if it is true that "idat1" equals "UN".  If
+       not, the original value of "idat1" is put back on the stack.  Lets call
+       this answer "d". The process is repeated for the next five items on the
+       stack, it is done the same and will return answer "h". The resulting
+       stack is therefore "d,h".  The expression has been simplified to
+       "d,h,+,8,*" and it will now be easy to see that we add "d" and "h", and
+       multiply the result with eight.
+
+       The end result is that we have added "idat1" and "idat2" and in the
+       process we effectively ignored unknown values. The result is multiplied
+       by eight, most likely to convert bytes/s to bits/s.

+
+       This demo demonstrates two ways to use infinity. It is a bit tricky to
+       see what happens in the "background" CDEF.
+
+          "val4,POP,TIME,7200,%,3600,LE,INF,UNKN,IF"
+
+       This RPN takes the value of "val4" as input and then immediately
+       removes it from the stack using "POP". The stack is now empty but as a
+       side effect we now know the time that this sample was taken.  This time
+       is put on the stack by the "TIME" function.
+
+       "TIME,7200,%" takes the modulo of time and 7'200 (which is two hours).
+       The resulting value on the stack will be a number in the range from 0
+       to 7199.
+
+       For people who don't know the modulo function: it is the remainder
+       after an integer division. If you divide 16 by 3, the answer would be 5
+       and the remainder would be 1. So, "16,3,%" returns 1.
+
+       We have the result of "TIME,7200,%" on the stack, lets call this "a".
+       The start of the RPN has become "a,3600,LE" and this checks if "a" is
+       less or equal than "3600". It is true half of the time.  We now have to
+       process the rest of the RPN and this is only a simple "IF" function
+       that returns either "INF" or "UNKN" depending on the time. This is
+       returned to variable "background".
+
+       The second CDEF has been discussed earlier in this document so we won't
+       do that here.
+
+       Now you can draw the different layers. Start with the background that
+       is either unknown (nothing to see) or infinite (the whole positive part
+       of the graph gets filled).
+
+       Next you draw the data on top of this background, it will overlay the
+       background. Suppose one of val1..val4 would be unknown, in that case
+       you end up with only three bars stacked on top of each other.  You
+       don't want to see this because the data is only valid when all four
+       variables are valid. This is why you use the second CDEF, it will over-
+       lay the data with an AREA so the data cannot be seen anymore.
+
+       If your data can also have negative values you also need to overwrite
+       the other half of your graph. This can be done in a relatively simple
+       way: what you need is the "wipeout" variable and place a negative sign
+       before it:  "CDEF:wipeout2=wipeout,-1,*"

+.TH RPNTUTORIAL 1 "2007-11-20" "1.2.26" "rrdtool"
+.SH "NAME"
+rpntutorial \- Reading RRDtool RPN Expressions by Steve Rader
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This tutorial should help you get to grips with RRDtool \s-1RPN\s0 expressions
+as seen in \s-1CDEF\s0 arguments of RRDtool graph.
+.SH "Reading Comparison Operators"
+.IX Header "Reading Comparison Operators"
+The \s-1LT\s0, \s-1LE\s0, \s-1GT\s0, \s-1GE\s0 and \s-1EQ\s0 \s-1RPN\s0 logic operators are not as tricky as
+they appear.  These operators act on the two values on the stack
+preceding them (to the left).  Read these two values on the stack
+from left to right inserting the operator in the middle.  If the
+resulting statement is true, then replace the three values from the
+stack with \*(L"1\*(R".  If the statement if false, replace the three values
+with \*(L"0\*(R".
+.PP
+For example, think about \*(L"2,1,GT\*(R".  This \s-1RPN\s0 expression could be
+read as \*(L"is two greater than one?\*(R"  The answer to that question is
+\&\*(L"true\*(R".  So the three values should be replaced with \*(L"1\*(R".  Thus the
+\&\s-1RPN\s0 expression 2,1,GT evaluates to 1.
+.PP
+Now consider \*(L"2,1,LE\*(R".  This \s-1RPN\s0 expression could be read as \*(L"is
+two less than or equal to one?\*(R".   The natural response is \*(L"no\*(R"
+and thus the \s-1RPN\s0 expression 2,1,LE evaluates to 0.
+.SH "Reading the IF Operator"
+.IX Header "Reading the IF Operator"
+The \s-1IF\s0 \s-1RPN\s0 logic operator can be straightforward also.  The key
+to reading \s-1IF\s0 operators is to understand that the condition part
+of the traditional \*(L"if X than Y else Z\*(R" notation has *already*
+been evaluated.  So the \s-1IF\s0 operator acts on only one value on the
+stack: the third value to the left of the \s-1IF\s0 value.  The second
+value to the left of the \s-1IF\s0 corresponds to the true (\*(L"Y\*(R") branch.
+And the first value to the left of the \s-1IF\s0 corresponds to the false
+(\*(L"Z\*(R") branch.  Read the \s-1RPN\s0 expression \*(L"X,Y,Z,IF\*(R" from left to
+right like so: \*(L"if X then Y else Z\*(R".
+.PP
+For example, consider \*(L"1,10,100,IF\*(R".  It looks bizarre to me.
+But when I read \*(L"if 1 then 10 else 100\*(R" it's crystal clear: 1 is true
+so the answer is 10.  Note that only zero is false; all other values
+are true.  \*(L"2,20,200,IF\*(R" (\*(L"if 2 then 20 else 200\*(R") evaluates to 20.
+And \*(L"0,1,2,IF\*(R" ("if 0 then 1 else 2) evaluates to 2.
+.PP
+Notice that none of the above examples really simulate the whole
+\&\*(L"if X then Y else Z\*(R" statement.  This is because computer programmers
+read this statement as \*(L"if Some Condition then Y else Z\*(R".  So it's
+important to be able to read \s-1IF\s0 operators along with the \s-1LT\s0, \s-1LE\s0,
+\&\s-1GT\s0, \s-1GE\s0 and \s-1EQ\s0 operators.
+.SH "Some Examples"
+.IX Header "Some Examples"
+While compound expressions can look overly complex, they can be
+considered elegantly simple.  To quickly comprehend \s-1RPN\s0 expressions,
+you must know the the algorithm for evaluating \s-1RPN\s0 expressions:
+iterate searches from the left to the right looking for an operator.
+When it's found, apply that operator by popping the operator and some
+number of values (and by definition, not operators) off the stack.
+.PP
+For example, the stack \*(L"1,2,3,+,+\*(R" gets \*(L"2,3,+\*(R" evaluated (as \*(L"2+3\*(R")
+during the first iteration and is replaced by 5.  This results in
+the stack \*(L"1,5,+\*(R".  Finally, \*(L"1,5,+\*(R" is evaluated resulting in the
+answer 6.  For convenience, it's useful to write this set of
+operations as:
+.PP
+.Vb 3
+\& 1) 1,2,3,+,+    eval is 2,3,+ = 5    result is 1,5,+
+\& 2) 1,5,+        eval is 1,5,+ = 6    result is 6
+\& 3) 6
+.Ve
+.PP
+Let's use that notation to conveniently solve some complex \s-1RPN\s0 expressions
+with multiple logic operators:
+.PP
+.Vb 1
+\& 1) 20,10,GT,10,20,IF  eval is 20,10,GT = 1     result is 1,10,20,IF
+.Ve
+.PP
+read the eval as pop \*(L"20 is greater than 10\*(R" so push 1
+.PP
+.Vb 1
+\& 2) 1,10,20,IF         eval is 1,10,20,IF = 10  result is 10
+.Ve
+.PP
+read pop \*(L"if 1 then 10 else 20\*(R" so push 10.  Only 10 is left so
+10 is the answer.
+.PP
+Let's read a complex \s-1RPN\s0 expression that also has the traditional
+multiplication operator:
+.PP
+.Vb 4
+\& 1) 128,8,*,7000,GT,7000,128,8,*,IF  eval 128,8,*       result is 1024
+\& 2) 1024,7000,GT,7000,128,8,*,IF     eval 1024,7000,GT  result is 0
+\& 3) 0,128,8,*,IF                     eval 128,8,*       result is 1024
+\& 4) 0,7000,1024,IF                                      result is 1024
+.Ve
+.PP
+Now let's go back to the first example of multiple logic operators,
+but replace the value 20 with the variable \*(L"input\*(R":
+.PP
+.Vb 1
+\& 1) input,10,GT,10,input,IF  eval is input,10,GT  ( lets call this A )
+.Ve
+.PP
+Read eval as \*(L"if input > 10 then true\*(R" and replace \*(L"input,10,GT\*(R"
+with \*(L"A\*(R":
+.PP
+.Vb 1
+\& 2) A,10,input,IF            eval is A,10,input,IF
+.Ve
+.PP
+read \*(L"if A then 10 else input\*(R".  Now replace A with it's verbose
+description againg and\*(--voila!\-\-you have a easily readable description
+of the expression:
+.PP
+.Vb 1
+\& if input > 10 then 10 else input
+.Ve
+.PP
+Finally, let's go back to the first most complex example and replace
+the value 128 with \*(L"input\*(R":
+.PP
+.Vb 1
+\& 1) input,8,*,7000,GT,7000,input,8,*,IF  eval input,8,*     result is A
+.Ve
+.PP
+where A is \*(L"input * 8\*(R"
+.PP
+.Vb 1
+\& 2) A,7000,GT,7000,input,8,*,IF          eval is A,7000,GT  result is B
+.Ve
+.PP
+where B is \*(L"if ((input * 8) > 7000) then true\*(R"
+.PP
+.Vb 1
+\& 3) B,7000,input,8,*,IF                  eval is input,8,*  result is C
+.Ve
+.PP
+where C is \*(L"input * 8\*(R"
+.PP
+.Vb 1
+\& 4) B,7000,C,IF
+.Ve
+.PP
+At last we have a readable decoding of the complex \s-1RPN\s0 expression with
+a variable:
+.PP
+.Vb 1
+\& if ((input * 8) > 7000) then 7000 else (input * 8)
+.Ve
+.SH "Exercises"
+.IX Header "Exercises"
+Exercise 1:
+.PP
+Compute \*(L"3,2,*,1,+ and \*(R"3,2,1,+,*" by hand.  Rewrite them in
+traditional notation.  Explain why they have different answers.
+.PP
+Answer 1:
+.PP
+.Vb 3
+\&    3*2+1 = 7 and 3*(2+1) = 9.  These expressions have
+\&    different answers because the altering of the plus and
+\&    times operators alter the order of their evaluation.
+.Ve
+.PP
+Exercise 2:
+.PP
+One may be tempted to shorten the expression
+.PP
+.Vb 1
+\& input,8,*,56000,GT,56000,input,*,8,IF
+.Ve
+.PP
+by removing the redundant use of \*(L"input,8,*\*(R" like so:
+.PP
+.Vb 1
+\& input,56000,GT,56000,input,IF,8,*
+.Ve
+.PP
+Use traditional notation to show these expressions are not the same.
+Write an expression that's equivalent to the first expression, but
+uses the \s-1LE\s0 and \s-1DIV\s0 operators.
+.PP
+Answer 2:
+.PP
+.Vb 2
+\&    if (input <= 56000/8 ) { input*8 } else { 56000 }
+\&    input,56000,8,DIV,LT,input,8,*,56000,IF
+.Ve
+.PP
+Exercise 3:
+.PP
+Briefly explain why traditional mathematic notation requires the
+use of parentheses.  Explain why \s-1RPN\s0 notation does not require
+the use of parentheses.
+.PP
+Answer 3:
+.PP
+.Vb 6
+\&    Traditional mathematic expressions are evaluated by
+\&    doing multiplication and division first, then addition and
+\&    subtraction.  Parentheses are used to force the evaluation of
+\&    addition before multiplication (etc).  RPN does not require
+\&    parentheses because the ordering of objects on the stack
+\&    can force the evaluation of addition before multiplication.
+.Ve
+.PP
+Exercise 4:
+.PP
+Explain why it was desirable for the RRDtool developers to implement
+\&\s-1RPN\s0 notation instead of traditional mathematical notation.
+.PP
+Answer 4:
+.PP
+.Vb 5
+\&    The algorithm that implements traditional mathematical
+\&    notation is more complex then algorithm used for RPN.
+\&    So implementing RPN allowed Tobias Oetiker to write less
+\&    code!  (The code is also less complex and therefore less
+\&    likely to have bugs.)

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>This tutorial should help you get to grips with RRDtool RPN expressions
+as seen in CDEF arguments of RRDtool graph.</p>

+<h1><a name="reading_comparison_operators">Reading Comparison Operators</a></h1>
+<p>The LT, LE, GT, GE and EQ RPN logic operators are not as tricky as
+they appear.  These operators act on the two values on the stack
+preceding them (to the left).  Read these two values on the stack
+from left to right inserting the operator in the middle.  If the
+resulting statement is true, then replace the three values from the
+stack with ``1''.  If the statement if false, replace the three values
+with ``0''.</p>
+<p>For example, think about ``2,1,GT''.  This RPN expression could be
+read as ``is two greater than one?''  The answer to that question is
+``true''.  So the three values should be replaced with ``1''.  Thus the
+RPN expression 2,1,GT evaluates to 1.</p>
+<p>Now consider ``2,1,LE''.  This RPN expression could be read as ``is
+two less than or equal to one?''.   The natural response is ``no''
+and thus the RPN expression 2,1,LE evaluates to 0.</p>
+<p>
+</p>
+<hr />
+<h1><a name="reading_the_if_operator">Reading the IF Operator</a></h1>
+<p>The IF RPN logic operator can be straightforward also.  The key
+to reading IF operators is to understand that the condition part
+of the traditional ``if X than Y else Z'' notation has *already*
+been evaluated.  So the IF operator acts on only one value on the
+stack: the third value to the left of the IF value.  The second
+value to the left of the IF corresponds to the true (``Y'') branch.
+And the first value to the left of the IF corresponds to the false
+(``Z'') branch.  Read the RPN expression ``X,Y,Z,IF'' from left to
+right like so: ``if X then Y else Z''.</p>
+<p>For example, consider ``1,10,100,IF''.  It looks bizarre to me.
+But when I read ``if 1 then 10 else 100'' it's crystal clear: 1 is true
+so the answer is 10.  Note that only zero is false; all other values
+are true.  ``2,20,200,IF'' (``if 2 then 20 else 200'') evaluates to 20.
+And ``0,1,2,IF'' (``if 0 then 1 else 2) evaluates to 2.</p>
+<p>Notice that none of the above examples really simulate the whole
+``if X then Y else Z'' statement.  This is because computer programmers
+read this statement as ``if Some Condition then Y else Z''.  So it's
+important to be able to read IF operators along with the LT, LE,
+GT, GE and EQ operators.</p>

+<h1><a name="some_examples">Some Examples</a></h1>
+<p>While compound expressions can look overly complex, they can be
+considered elegantly simple.  To quickly comprehend RPN expressions,
+you must know the the algorithm for evaluating RPN expressions:
+iterate searches from the left to the right looking for an operator.
+When it's found, apply that operator by popping the operator and some
+number of values (and by definition, not operators) off the stack.</p>
+<p>For example, the stack ``1,2,3,+,+'' gets ``2,3,+'' evaluated (as ``2+3'')
+during the first iteration and is replaced by 5.  This results in
+the stack ``1,5,+''.  Finally, ``1,5,+'' is evaluated resulting in the
+answer 6.  For convenience, it's useful to write this set of
+operations as:</p>
+<pre>
+ 1) 1,2,3,+,+    eval is 2,3,+ = 5    result is 1,5,+
+ 2) 1,5,+        eval is 1,5,+ = 6    result is 6
+ 3) 6</pre>
+<p>Let's use that notation to conveniently solve some complex RPN expressions
+with multiple logic operators:</p>
+<pre>
+ 1) 20,10,GT,10,20,IF  eval is 20,10,GT = 1     result is 1,10,20,IF</pre>
+<p>read the eval as pop ``20 is greater than 10'' so push 1</p>
+<pre>
+ 2) 1,10,20,IF         eval is 1,10,20,IF = 10  result is 10</pre>
+<p>read pop ``if 1 then 10 else 20'' so push 10.  Only 10 is left so
+10 is the answer.</p>
+<p>Let's read a complex RPN expression that also has the traditional
+multiplication operator:</p>
+<pre>
+ 1) 128,8,*,7000,GT,7000,128,8,*,IF  eval 128,8,*       result is 1024
+ 2) 1024,7000,GT,7000,128,8,*,IF     eval 1024,7000,GT  result is 0
+ 3) 0,128,8,*,IF                     eval 128,8,*       result is 1024
+ 4) 0,7000,1024,IF                                      result is 1024</pre>
+<p>Now let's go back to the first example of multiple logic operators,
+but replace the value 20 with the variable ``input'':</p>
+<pre>
+ 1) input,10,GT,10,input,IF  eval is input,10,GT  ( lets call this A )</pre>
+<p>Read eval as ``if input &gt; 10 then true'' and replace ``input,10,GT''
+with ``A'':</p>
+<pre>
+ 2) A,10,input,IF            eval is A,10,input,IF</pre>
+<p>read ``if A then 10 else input''.  Now replace A with it's verbose
+description againg and--voila!--you have a easily readable description
+of the expression:</p>
+<pre>
+ if input &gt; 10 then 10 else input</pre>
+<p>Finally, let's go back to the first most complex example and replace
+the value 128 with ``input'':</p>
+<pre>
+ 1) input,8,*,7000,GT,7000,input,8,*,IF  eval input,8,*     result is A</pre>
+<p>where A is ``input * 8''</p>
+<pre>
+ 2) A,7000,GT,7000,input,8,*,IF          eval is A,7000,GT  result is B</pre>
+<p>where B is ``if ((input * 8) &gt; 7000) then true''</p>
+<pre>
+ 3) B,7000,input,8,*,IF                  eval is input,8,*  result is C</pre>
+<p>where C is ``input * 8''</p>
+<pre>
+ 4) B,7000,C,IF</pre>
+<p>At last we have a readable decoding of the complex RPN expression with
+a variable:</p>
+<pre>
+ if ((input * 8) &gt; 7000) then 7000 else (input * 8)</pre>

+<h1><a name="exercises">Exercises</a></h1>
+<p>Exercise 1:</p>
+<p>Compute ``3,2,*,1,+ and ''3,2,1,+,*`` by hand.  Rewrite them in
+traditional notation.  Explain why they have different answers.</p>
+<p>Answer 1:</p>
+<pre>
+    3*2+1 = 7 and 3*(2+1) = 9.  These expressions have

+<p>Exercise 2:</p>
+<p>One may be tempted to shorten the expression</p>
+<pre>
+ input,8,*,56000,GT,56000,input,*,8,IF</pre>
+<p>by removing the redundant use of ``input,8,*'' like so:</p>
+<pre>
+ input,56000,GT,56000,input,IF,8,*</pre>
+<p>Use traditional notation to show these expressions are not the same.
+Write an expression that's equivalent to the first expression, but

+<p>Answer 2:</p>
+<pre>

+<p>Exercise 3:</p>
+<p>Briefly explain why traditional mathematic notation requires the
+use of parentheses.  Explain why RPN notation does not require
+the use of parentheses.</p>
+<p>Answer 3:</p>
+<pre>
+    Traditional mathematic expressions are evaluated by
+    doing multiplication and division first, then addition and
+    subtraction.  Parentheses are used to force the evaluation of
+    addition before multiplication (etc).  RPN does not require
+    parentheses because the ordering of objects on the stack
+    can force the evaluation of addition before multiplication.</pre>
+<p>Exercise 4:</p>
+<p>Explain why it was desirable for the RRDtool developers to implement
+RPN notation instead of traditional mathematical notation.</p>
+<p>Answer 4:</p>
+<pre>
+    The algorithm that implements traditional mathematical
+    notation is more complex then algorithm used for RPN.
+    So implementing RPN allowed Tobias Oetiker to write less

+rpntutorial - Reading RRDtool RPN Expressions by Steve Rader
+
+=head1 DESCRIPTION
+
+This tutorial should help you get to grips with RRDtool RPN expressions
+as seen in CDEF arguments of RRDtool graph.
+
+=head1 Reading Comparison Operators
+
+The LT, LE, GT, GE and EQ RPN logic operators are not as tricky as
+they appear.  These operators act on the two values on the stack
+preceding them (to the left).  Read these two values on the stack
+from left to right inserting the operator in the middle.  If the
+resulting statement is true, then replace the three values from the
+stack with "1".  If the statement if false, replace the three values
+with "0".
+
+For example, think about "2,1,GT".  This RPN expression could be
+read as "is two greater than one?"  The answer to that question is
+"true".  So the three values should be replaced with "1".  Thus the
+RPN expression 2,1,GT evaluates to 1.
+
+Now consider "2,1,LE".  This RPN expression could be read as "is
+two less than or equal to one?".   The natural response is "no"
+and thus the RPN expression 2,1,LE evaluates to 0.
+
+=head1 Reading the IF Operator
+
+The IF RPN logic operator can be straightforward also.  The key
+to reading IF operators is to understand that the condition part
+of the traditional "if X than Y else Z" notation has *already*
+been evaluated.  So the IF operator acts on only one value on the
+stack: the third value to the left of the IF value.  The second
+value to the left of the IF corresponds to the true ("Y") branch.
+And the first value to the left of the IF corresponds to the false
+("Z") branch.  Read the RPN expression "X,Y,Z,IF" from left to
+right like so: "if X then Y else Z".
+
+For example, consider "1,10,100,IF".  It looks bizarre to me.
+But when I read "if 1 then 10 else 100" it's crystal clear: 1 is true
+so the answer is 10.  Note that only zero is false; all other values
+are true.  "2,20,200,IF" ("if 2 then 20 else 200") evaluates to 20.
+And "0,1,2,IF" ("if 0 then 1 else 2) evaluates to 2.
+
+
+Notice that none of the above examples really simulate the whole
+"if X then Y else Z" statement.  This is because computer programmers
+read this statement as "if Some Condition then Y else Z".  So it's
+important to be able to read IF operators along with the LT, LE,
+GT, GE and EQ operators.
+
+=head1 Some Examples
+
+While compound expressions can look overly complex, they can be
+considered elegantly simple.  To quickly comprehend RPN expressions,
+you must know the the algorithm for evaluating RPN expressions:
+iterate searches from the left to the right looking for an operator.
+When it's found, apply that operator by popping the operator and some
+number of values (and by definition, not operators) off the stack.
+
+For example, the stack "1,2,3,+,+" gets "2,3,+" evaluated (as "2+3")
+during the first iteration and is replaced by 5.  This results in
+the stack "1,5,+".  Finally, "1,5,+" is evaluated resulting in the
+answer 6.  For convenience, it's useful to write this set of
+operations as:
+
+ 1) 1,2,3,+,+    eval is 2,3,+ = 5    result is 1,5,+
+ 2) 1,5,+        eval is 1,5,+ = 6    result is 6
+ 3) 6
+
+Let's use that notation to conveniently solve some complex RPN expressions
+with multiple logic operators:
+
+ 1) 20,10,GT,10,20,IF  eval is 20,10,GT = 1     result is 1,10,20,IF
+
+read the eval as pop "20 is greater than 10" so push 1
+
+ 2) 1,10,20,IF         eval is 1,10,20,IF = 10  result is 10
+
+read pop "if 1 then 10 else 20" so push 10.  Only 10 is left so
+10 is the answer.
+
+Let's read a complex RPN expression that also has the traditional
+multiplication operator:
+
+ 1) 128,8,*,7000,GT,7000,128,8,*,IF  eval 128,8,*       result is 1024
+ 2) 1024,7000,GT,7000,128,8,*,IF     eval 1024,7000,GT  result is 0
+ 3) 0,128,8,*,IF                     eval 128,8,*       result is 1024
+ 4) 0,7000,1024,IF                                      result is 1024
+
+
+Now let's go back to the first example of multiple logic operators,
+but replace the value 20 with the variable "input":
+
+ 1) input,10,GT,10,input,IF  eval is input,10,GT  ( lets call this A )
+
+Read eval as "if input > 10 then true" and replace "input,10,GT"
+with "A":
+
+ 2) A,10,input,IF            eval is A,10,input,IF
+
+read "if A then 10 else input".  Now replace A with it's verbose
+description againg and--voila!--you have a easily readable description
+of the expression:
+
+ if input > 10 then 10 else input
+
+Finally, let's go back to the first most complex example and replace
+the value 128 with "input":
+
+ 1) input,8,*,7000,GT,7000,input,8,*,IF  eval input,8,*     result is A
+
+where A is "input * 8"
+
+ 2) A,7000,GT,7000,input,8,*,IF          eval is A,7000,GT  result is B
+
+where B is "if ((input * 8) > 7000) then true"
+
+ 3) B,7000,input,8,*,IF                  eval is input,8,*  result is C
+
+where C is "input * 8"
+
+ 4) B,7000,C,IF
+
+At last we have a readable decoding of the complex RPN expression with
+a variable:
+
+ if ((input * 8) > 7000) then 7000 else (input * 8)
+
+=head1 Exercises
+
+Exercise 1:
+
+Compute "3,2,*,1,+ and "3,2,1,+,*" by hand.  Rewrite them in
+traditional notation.  Explain why they have different answers.
+
+Answer 1:
+
+    3*2+1 = 7 and 3*(2+1) = 9.  These expressions have
+    different answers because the altering of the plus and
+    times operators alter the order of their evaluation.
+
+
+Exercise 2:
+
+One may be tempted to shorten the expression
+
+ input,8,*,56000,GT,56000,input,*,8,IF
+
+by removing the redundant use of "input,8,*" like so:
+
+ input,56000,GT,56000,input,IF,8,*
+
+Use traditional notation to show these expressions are not the same.
+Write an expression that's equivalent to the first expression, but
+uses the LE and DIV operators.
+
+Answer 2:
+
+    if (input <= 56000/8 ) { input*8 } else { 56000 }
+    input,56000,8,DIV,LT,input,8,*,56000,IF
+
+
+Exercise 3:
+
+Briefly explain why traditional mathematic notation requires the
+use of parentheses.  Explain why RPN notation does not require
+the use of parentheses.
+
+Answer 3:
+
+    Traditional mathematic expressions are evaluated by
+    doing multiplication and division first, then addition and
+    subtraction.  Parentheses are used to force the evaluation of
+    addition before multiplication (etc).  RPN does not require

+    can force the evaluation of addition before multiplication.
+
+
+Exercise 4:
+
+Explain why it was desirable for the RRDtool developers to implement
+RPN notation instead of traditional mathematical notation.
+
+Answer 4:
+
+    The algorithm that implements traditional mathematical

+       read the eval as pop "20 is greater than 10" so push 1
+
+        2) 1,10,20,IF         eval is 1,10,20,IF = 10  result is 10
+
+       read pop "if 1 then 10 else 20" so push 10.  Only 10 is left so 10 is
+       the answer.
+
+       Let's read a complex RPN expression that also has the traditional mul-
+       tiplication operator:
+
+        1) 128,8,*,7000,GT,7000,128,8,*,IF  eval 128,8,*       result is 1024
+        2) 1024,7000,GT,7000,128,8,*,IF     eval 1024,7000,GT  result is 0
+        3) 0,128,8,*,IF                     eval 128,8,*       result is 1024
+        4) 0,7000,1024,IF                                      result is 1024
+
+       Now let's go back to the first example of multiple logic operators, but
+       replace the value 20 with the variable "input":
+
+        1) input,10,GT,10,input,IF  eval is input,10,GT  ( lets call this A )
+
+       Read eval as "if input > 10 then true" and replace "input,10,GT" with
+       "A":
+
+        2) A,10,input,IF            eval is A,10,input,IF
+
+       read "if A then 10 else input".  Now replace A with it's verbose
+       description againg and--voila!--you have a easily readable description
+       of the expression:
+
+        if input > 10 then 10 else input
+
+       Finally, let's go back to the first most complex example and replace
+       the value 128 with "input":
+
+        1) input,8,*,7000,GT,7000,input,8,*,IF  eval input,8,*     result is A
+
+       where A is "input * 8"
+
+        2) A,7000,GT,7000,input,8,*,IF          eval is A,7000,GT  result is B
+
+       where B is "if ((input * 8) > 7000) then true"
+
+        3) B,7000,input,8,*,IF                  eval is input,8,*  result is C
+
+       where C is "input * 8"
+
+        4) B,7000,C,IF
+
+       At last we have a readable decoding of the complex RPN expression with
+       a variable:
+
+        if ((input * 8) > 7000) then 7000 else (input * 8)

+       Exercise 1:
+
+       Compute "3,2,*,1,+ and "3,2,1,+,*" by hand.  Rewrite them in tradi-
+       tional notation.  Explain why they have different answers.
+
+       Answer 1:
+
+           3*2+1 = 7 and 3*(2+1) = 9.  These expressions have
+           different answers because the altering of the plus and
+           times operators alter the order of their evaluation.
+
+       Exercise 2:
+
+       One may be tempted to shorten the expression
+
+        input,8,*,56000,GT,56000,input,*,8,IF
+
+       by removing the redundant use of "input,8,*" like so:
+
+        input,56000,GT,56000,input,IF,8,*
+
+       Use traditional notation to show these expressions are not the same.
+       Write an expression that's equivalent to the first expression, but uses
+       the LE and DIV operators.
+
+       Answer 2:
+
+           if (input <= 56000/8 ) { input*8 } else { 56000 }
+           input,56000,8,DIV,LT,input,8,*,56000,IF
+
+       Exercise 3:
+
+       Briefly explain why traditional mathematic notation requires the use of
+       parentheses.  Explain why RPN notation does not require the use of
+       parentheses.
+
+       Answer 3:
+
+           Traditional mathematic expressions are evaluated by
+           doing multiplication and division first, then addition and
+           subtraction.  Parentheses are used to force the evaluation of
+           addition before multiplication (etc).  RPN does not require
+           parentheses because the ordering of objects on the stack
+           can force the evaluation of addition before multiplication.
+
+       Exercise 4:
+
+       Explain why it was desirable for the RRDtool developers to implement
+       RPN notation instead of traditional mathematical notation.
+
+       Answer 4:
+
+           The algorithm that implements traditional mathematical
+           notation is more complex then algorithm used for RPN.
+           So implementing RPN allowed Tobias Oetiker to write less
+           code!  (The code is also less complex and therefore less
+           likely to have bugs.)

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This manual is an attempt to assist beginners in understanding the concepts
+of RRDtool. It sheds a light on differences between RRDtool and other
+databases. With help of an example, it explains the structure of RRDtool
+database. This is followed by an overview of the \*(L"graph\*(R" feature of RRDtool.
+At the end, it has sample scripts that illustrate the
+usage/wrapping of RRDtool within Shell or Perl scripts.
+.Sh "What makes RRDtool so special?"
+.IX Subsection "What makes RRDtool so special?"
+RRDtool is \s-1GNU\s0 licensed software developed by Tobias Oetiker, a system
+manager at the Swiss Federal Institute of Technology. Though it is a
+database, there are distinct differences between RRDtool databases and other
+databases as listed below:
+.IP "\(bu" 4
+RRDtool stores data; that makes it a back-end tool. The RRDtool command set
+allows the creation of graphs; that makes it a front-end tool as well. Other
+databases just store data and can not create graphs.
+.IP "\(bu" 4
+In case of linear databases, new data gets appended at the bottom of
+the database table. Thus its size keeps on increasing, whereas the size of
+an RRDtool database is determined at creation time. Imagine an RRDtool
+database as the perimeter of a circle. Data is added along the
+perimeter. When new data reaches the starting point, it overwrites
+existing data. This way, the size of an RRDtool database always
+remains constant. The name \*(L"Round Robin\*(R" stems from this behavior.
+.IP "\(bu" 4
+Other databases store the values as supplied. RRDtool can be configured to
+calculate the rate of change from the previous to the current value and
+store this information instead.
+.IP "\(bu" 4
+Other databases get updated when values are supplied. The RRDtool database
+is structured in such a way that it needs data at predefined time
+intervals. If it does not get a new value during the interval, it stores an
+\&\s-1UNKNOWN\s0 value for that interval. So, when using the RRDtool database, it is
+imperative to use scripts that run at regular intervals to ensure a constant
+data flow to update the RRDtool database.
+.PP
+RRDtool is designed to store time series of data. With every data
+update, an associated time stamp is stored. Time is always expressed
+in seconds passed since epoch (01\-01\-1970). RRDtool can be installed
+on Unix as well as Windows. It comes with a command set to carry out
+various operations on \s-1RRD\s0 databases. This command set can be accessed
+from the command line, as well as from Shell or Perl scripts. The
+scripts act as wrappers for accessing data stored in RRDtool
+databases.
+.Sh "Understanding by an example"
+.IX Subsection "Understanding by an example"
+The structure of an \s-1RRD\s0 database is different than other linear databases.
+Other databases define tables with columns, and many other parameters. These
+definitions sometimes are very complex, especially in large databases.
+RRDtool databases are primarily used for monitoring purposes and
+hence are very simple in structure. The parameters
+that need to be defined are variables that hold values and archives of those
+values. Being time sensitive, a couple of time related parameters are also
+defined. Because of its structure, the definition of an RRDtool database also
+includes a provision to specify specific actions to take in the absence of
+update values. Data Source (\s-1DS\s0), heartbeat, Date Source Type (\s-1DST\s0), Round
+Robin Archive (\s-1RRA\s0), and Consolidation Function (\s-1CF\s0) are some of the
+terminologies related to RRDtool databases.
+.PP
+The structure of a database and the terminology associated with it can be
+best explained with an example.
+.PP
+.Vb 6
+\& rrdtool create target.rrd \e
+\&         \-\-start 1023654125 \e
+\&         \-\-step 300 \e
+\&         DS:mem:GAUGE:600:0:671744 \e
+\&         RRA:AVERAGE:0.5:12:24 \e
+\&         RRA:AVERAGE:0.5:288:31
+.Ve
+.PP
+This example creates a database named \fItarget.rrd\fR. Start time
+(1'023'654'125) is specified in total number of seconds since epoch
+(time in seconds since 01\-01\-1970). While updating the database, the
+update time is also specified.  This update time \s-1MUST\s0 be large (later)
+then start time and \s-1MUST\s0 be in seconds since epoch.
+.PP
+The step of 300 seconds indicates that database expects new values every
+300 seconds. The wrapper script should be scheduled to run every \fBstep\fR
+seconds so that it updates the database every \fBstep\fR seconds.
+.PP
+\&\s-1DS\s0 (Data Source) is the actual variable which relates to the parameter on
+the device that is monitored. Its syntax is
+.PP
+.Vb 1
+\& DS:variable_name:DST:heartbeat:min:max
+.Ve
+.PP
+\&\fB\s-1DS\s0\fR is a key word. \f(CW\*(C`variable_name\*(C'\fR is a name under which the parameter is
+saved in the database. There can be as many DSs in a database as needed. After
+every step interval, a new value of \s-1DS\s0 is supplied to update the database.
+This value is also called Primary Data Point \fB(\s-1PDP\s0)\fR. In our example
+mentioned above, a new \s-1PDP\s0 is generated every 300 seconds.
+.PP
+Note, that if you do \s-1NOT\s0 supply new datapoints exactly every 300 seconds,
+this is not a problem, RRDtool will interpolate the data accordingly.
+.PP
+\&\fB\s-1DST\s0\fR (Data Source Type) defines the type of the \s-1DS\s0. It can be
+\&\s-1COUNTER\s0, \s-1DERIVE\s0, \s-1ABSOLUTE\s0, \s-1GAUGE\s0. A \s-1DS\s0 declared as \s-1COUNTER\s0 will save
+the rate of change of the value over a step period. This assumes that
+the value is always increasing (the difference between the current and
+the previous value is greater than 0). Traffic counters on a router
+are an ideal candidate for using \s-1COUNTER\s0 as \s-1DST\s0. \s-1DERIVE\s0 is the same as
+\&\s-1COUNTER\s0, but it allows negative values as well. If you want to see the
+rate of \fIchange\fR in free diskspace on your server, then you might
+want to use the \s-1DERIVE\s0 data type. \s-1ABSOLUTE\s0 also saves the rate of
+change, but it assumes that the previous value is set to 0. The
+difference between the current and the previous value is always equal
+to the current value. Thus it just stores the current value divided by
+the step interval (300 seconds in our example). \s-1GAUGE\s0 does not save
+the rate of change. It saves the actual value itself. There are no
+divisions or calculations. Memory consumption in a server is a typical
+example of gauge. The difference between the different types DSTs can be
+explained better with the following example:
+.PP
+.Vb 6
+\& Values       = 300, 600, 900, 1200
+\& Step         = 300 seconds
+\& COUNTER DS   =    1,  1,   1,    1
+\& DERIVE DS    =    1,  1,   1,    1
+\& ABSOLUTE DS  =    1,  2,   3,    4
+\& GAUGE DS     = 300, 600, 900, 1200
+.Ve
+.PP
+The next parameter is \fBheartbeat\fR. In our example, heartbeat is 600
+seconds. If the database does not get a new \s-1PDP\s0 within 300 seconds, it
+will wait for another 300 seconds (total 600 seconds).  If it doesn't
+receive any \s-1PDP\s0 within 600 seconds, it will save an \s-1UNKNOWN\s0 value into
+the database. This \s-1UNKNOWN\s0 value is a special feature of RRDtool \- it
+is much better than to assume a missing value was 0 (zero) or any
+other number which might also be a valid data value.  For example, the
+traffic flow counter on a router keeps increasing. Lets say, a value
+is missed for an interval and 0 is stored instead of \s-1UNKNOWN\s0. Now when
+the next value becomes available, it will calculate the difference
+between the current value and the previous value (0) which is not
+correct. So, inserting the value \s-1UNKNOWN\s0 makes much more sense here.
+.PP
+The next two parameters are the minimum and maximum value,
+respectively. If the variable to be stored has predictable maximum and
+minimum values, this should be specified here. Any update value
+falling out of this range will be stored as \s-1UNKNOWN\s0.
+.PP
+The next line declares a round robin archive (\s-1RRA\s0). The syntax for
+declaring an \s-1RRA\s0 is
+.PP
+.Vb 1
+\& RRA:CF:xff:step:rows
+.Ve
+.PP
+\&\s-1RRA\s0 is the keyword to declare RRAs. The consolidation function (\s-1CF\s0)
+can be \s-1AVERAGE\s0, \s-1MINIMUM\s0, \s-1MAXIMUM\s0, and \s-1LAST\s0. The concept of the
+consolidated data point (\s-1CDP\s0) comes into the picture here. A \s-1CDP\s0 is
+CFed (averaged, maximum/minimum value or last value) from \fIstep\fR
+number of PDPs. This \s-1RRA\s0 will hold \fIrows\fR CDPs.
+.PP
+Lets have a look at the example above. For the first \s-1RRA\s0, 12 (steps)
+PDPs (\s-1DS\s0 variables) are AVERAGEed (\s-1CF\s0) to form one \s-1CDP\s0. 24 (rows) of
+theses CDPs are archived. Each \s-1PDP\s0 occurs at 300 seconds. 12 PDPs
+represent 12 times 300 seconds which is 1 hour. It means 1 \s-1CDP\s0 (which
+is equal to 12 PDPs) represents data worth 1 hour. 24 such CDPs
+represent 1 day (1 hour times 24 CDPs). This means, this \s-1RRA\s0 is an
+archive for one day. After 24 CDPs, \s-1CDP\s0 number 25 will replace the 1st
+\&\s-1CDP\s0. The second \s-1RRA\s0 saves 31 CDPs; each \s-1CPD\s0 represents an \s-1AVERAGE\s0
+value for a day (288 PDPs, each covering 300 seconds = 24
+hours). Therefore this \s-1RRA\s0 is an archive for one month. A single
+database can have many RRAs. If there are multiple DSs, each
+individual \s-1RRA\s0 will save data for all the DSs in the database. For
+example, if a database has 3 DSs and daily, weekly, monthly, and
+yearly RRAs are declared, then each \s-1RRA\s0 will hold data from all 3 data
+sources.
+.Sh "Graphical Magic"
+.IX Subsection "Graphical Magic"
+Another important feature of RRDtool is its ability to create
+graphs. The \*(L"graph\*(R" command uses the \*(L"fetch\*(R" command internally to
+retrieve values from the database. With the retrieved values it draws
+graphs as defined by the parameters supplied on the command line. A
+single graph can show different \s-1DS\s0 (Data Sources) from a database. It
+is also possible to show the values from more than one database in a
+single graph. Often, it is necessary to perform some math on the
+values retrieved from the database before plotting them. For example,
+in \s-1SNMP\s0 replies, memory consumption values are usually specified in
+KBytes and traffic flow on interfaces is specified in Bytes. Graphs
+for these values will be more meaningful if values are represented in
+MBytes and mbps. The RRDtool graph command allows to define such
+conversions. Apart from mathematical calculations, it is also possible
+to perform logical operations such as greater than, less than, and
+if/then/else. If a database contains more than one \s-1RRA\s0 archive, then a
+question may arise \- how does RRDtool decide which \s-1RRA\s0 archive to use
+for retrieving the values? RRDtool looks at several things when making
+its choice. First it makes sure that the \s-1RRA\s0 covers as much of the
+graphing time frame as possible. Second it looks at the resolution of
+the \s-1RRA\s0 compared to the resolution of the graph. It tries to find one
+which has the same or higher better resolution. With the \*(L"\-r\*(R" option
+you can force RRDtool to assume a different resolution than the one
+calculated from the pixel width of the graph.

+in scripts. Tasks involved in network management are data collection,
+data storage, and data retrieval. In the following example, the
+previously created target.rrd database is used. Data collection and
+data storage is done using Shell scripts. Data retrieval and report

+<p>This manual is an attempt to assist beginners in understanding the concepts
+of RRDtool. It sheds a light on differences between RRDtool and other
+databases. With help of an example, it explains the structure of RRDtool
+database. This is followed by an overview of the ``graph'' feature of RRDtool.
+At the end, it has sample scripts that illustrate the
+usage/wrapping of RRDtool within Shell or Perl scripts.</p>
+<p>
+</p>
+<h2><a name="what_makes_rrdtool_so_special">What makes RRDtool so special?</a></h2>
+<p>RRDtool is GNU licensed software developed by Tobias Oetiker, a system
+manager at the Swiss Federal Institute of Technology. Though it is a
+database, there are distinct differences between RRDtool databases and other
+databases as listed below:</p>
+<ul>
+<li>
+<p>RRDtool stores data; that makes it a back-end tool. The RRDtool command set
+allows the creation of graphs; that makes it a front-end tool as well. Other
+databases just store data and can not create graphs.</p>
+</li>
+<li>
+<p>In case of linear databases, new data gets appended at the bottom of
+the database table. Thus its size keeps on increasing, whereas the size of
+an RRDtool database is determined at creation time. Imagine an RRDtool
+database as the perimeter of a circle. Data is added along the
+perimeter. When new data reaches the starting point, it overwrites
+existing data. This way, the size of an RRDtool database always
+remains constant. The name ``Round Robin'' stems from this behavior.</p>
+</li>
+<li>
+<p>Other databases store the values as supplied. RRDtool can be configured to
+calculate the rate of change from the previous to the current value and
+store this information instead.</p>
+</li>
+<li>
+<p>Other databases get updated when values are supplied. The RRDtool database
+is structured in such a way that it needs data at predefined time
+intervals. If it does not get a new value during the interval, it stores an
+UNKNOWN value for that interval. So, when using the RRDtool database, it is
+imperative to use scripts that run at regular intervals to ensure a constant
+data flow to update the RRDtool database.</p>
+</li>
+</ul>
+<p>RRDtool is designed to store time series of data. With every data
+update, an associated time stamp is stored. Time is always expressed
+in seconds passed since epoch (01-01-1970). RRDtool can be installed
+on Unix as well as Windows. It comes with a command set to carry out
+various operations on RRD databases. This command set can be accessed
+from the command line, as well as from Shell or Perl scripts. The
+scripts act as wrappers for accessing data stored in RRDtool
+databases.</p>
+<p>
+</p>
+<h2><a name="understanding_by_an_example">Understanding by an example</a></h2>
+<p>The structure of an RRD database is different than other linear databases.
+Other databases define tables with columns, and many other parameters. These
+definitions sometimes are very complex, especially in large databases.
+RRDtool databases are primarily used for monitoring purposes and
+hence are very simple in structure. The parameters
+that need to be defined are variables that hold values and archives of those
+values. Being time sensitive, a couple of time related parameters are also
+defined. Because of its structure, the definition of an RRDtool database also
+includes a provision to specify specific actions to take in the absence of
+update values. Data Source (DS), heartbeat, Date Source Type (DST), Round
+Robin Archive (RRA), and Consolidation Function (CF) are some of the
+terminologies related to RRDtool databases.</p>
+<p>The structure of a database and the terminology associated with it can be
+best explained with an example.</p>
+<pre>
+ rrdtool create target.rrd \
+         --start 1023654125 \
+         --step 300 \
+         DS:mem:GAUGE:600:0:671744 \
+         RRA:AVERAGE:0.5:12:24 \
+         RRA:AVERAGE:0.5:288:31</pre>
+<p>This example creates a database named <em>target.rrd</em>. Start time
+(1'023'654'125) is specified in total number of seconds since epoch
+(time in seconds since 01-01-1970). While updating the database, the
+update time is also specified.  This update time MUST be large (later)
+then start time and MUST be in seconds since epoch.</p>
+<p>The step of 300 seconds indicates that database expects new values every
+300 seconds. The wrapper script should be scheduled to run every <strong>step</strong>
+seconds so that it updates the database every <strong>step</strong> seconds.</p>
+<p>DS (Data Source) is the actual variable which relates to the parameter on
+the device that is monitored. Its syntax is</p>
+<pre>
+ DS:variable_name:DST:heartbeat:min:max</pre>
+<p><strong>DS</strong> is a key word. <code>variable_name</code> is a name under which the parameter is
+saved in the database. There can be as many DSs in a database as needed. After
+every step interval, a new value of DS is supplied to update the database.
+This value is also called Primary Data Point <strong>(PDP)</strong>. In our example
+mentioned above, a new PDP is generated every 300 seconds.</p>
+<p>Note, that if you do NOT supply new datapoints exactly every 300 seconds,
+this is not a problem, RRDtool will interpolate the data accordingly.</p>
+<p><strong>DST</strong> (Data Source Type) defines the type of the DS. It can be
+COUNTER, DERIVE, ABSOLUTE, GAUGE. A DS declared as COUNTER will save
+the rate of change of the value over a step period. This assumes that
+the value is always increasing (the difference between the current and
+the previous value is greater than 0). Traffic counters on a router
+are an ideal candidate for using COUNTER as DST. DERIVE is the same as
+COUNTER, but it allows negative values as well. If you want to see the
+rate of <em>change</em> in free diskspace on your server, then you might
+want to use the DERIVE data type. ABSOLUTE also saves the rate of
+change, but it assumes that the previous value is set to 0. The
+difference between the current and the previous value is always equal
+to the current value. Thus it just stores the current value divided by
+the step interval (300 seconds in our example). GAUGE does not save
+the rate of change. It saves the actual value itself. There are no
+divisions or calculations. Memory consumption in a server is a typical
+example of gauge. The difference between the different types DSTs can be
+explained better with the following example:</p>
+<pre>
+ Values       = 300, 600, 900, 1200
+ Step         = 300 seconds
+ COUNTER DS   =    1,  1,   1,    1
+ DERIVE DS    =    1,  1,   1,    1
+ ABSOLUTE DS  =    1,  2,   3,    4
+ GAUGE DS     = 300, 600, 900, 1200</pre>
+<p>The next parameter is <strong>heartbeat</strong>. In our example, heartbeat is 600
+seconds. If the database does not get a new PDP within 300 seconds, it
+will wait for another 300 seconds (total 600 seconds).  If it doesn't
+receive any PDP within 600 seconds, it will save an UNKNOWN value into
+the database. This UNKNOWN value is a special feature of RRDtool - it
+is much better than to assume a missing value was 0 (zero) or any
+other number which might also be a valid data value.  For example, the
+traffic flow counter on a router keeps increasing. Lets say, a value
+is missed for an interval and 0 is stored instead of UNKNOWN. Now when
+the next value becomes available, it will calculate the difference
+between the current value and the previous value (0) which is not
+correct. So, inserting the value UNKNOWN makes much more sense here.</p>
+<p>The next two parameters are the minimum and maximum value,
+respectively. If the variable to be stored has predictable maximum and
+minimum values, this should be specified here. Any update value
+falling out of this range will be stored as UNKNOWN.</p>
+<p>The next line declares a round robin archive (RRA). The syntax for
+declaring an RRA is</p>
+<pre>
+ RRA:CF:xff:step:rows</pre>
+<p>RRA is the keyword to declare RRAs. The consolidation function (CF)
+can be AVERAGE, MINIMUM, MAXIMUM, and LAST. The concept of the
+consolidated data point (CDP) comes into the picture here. A CDP is
+CFed (averaged, maximum/minimum value or last value) from <em>step</em>
+number of PDPs. This RRA will hold <em>rows</em> CDPs.</p>
+<p>Lets have a look at the example above. For the first RRA, 12 (steps)
+PDPs (DS variables) are AVERAGEed (CF) to form one CDP. 24 (rows) of
+theses CDPs are archived. Each PDP occurs at 300 seconds. 12 PDPs
+represent 12 times 300 seconds which is 1 hour. It means 1 CDP (which
+is equal to 12 PDPs) represents data worth 1 hour. 24 such CDPs
+represent 1 day (1 hour times 24 CDPs). This means, this RRA is an
+archive for one day. After 24 CDPs, CDP number 25 will replace the 1st
+CDP. The second RRA saves 31 CDPs; each CPD represents an AVERAGE
+value for a day (288 PDPs, each covering 300 seconds = 24
+hours). Therefore this RRA is an archive for one month. A single
+database can have many RRAs. If there are multiple DSs, each
+individual RRA will save data for all the DSs in the database. For
+example, if a database has 3 DSs and daily, weekly, monthly, and
+yearly RRAs are declared, then each RRA will hold data from all 3 data
+sources.</p>
+<p>
+</p>
+<h2><a name="graphical_magic">Graphical Magic</a></h2>
+<p>Another important feature of RRDtool is its ability to create
+graphs. The ``graph'' command uses the ``fetch'' command internally to
+retrieve values from the database. With the retrieved values it draws
+graphs as defined by the parameters supplied on the command line. A
+single graph can show different DS (Data Sources) from a database. It
+is also possible to show the values from more than one database in a
+single graph. Often, it is necessary to perform some math on the
+values retrieved from the database before plotting them. For example,
+in SNMP replies, memory consumption values are usually specified in
+KBytes and traffic flow on interfaces is specified in Bytes. Graphs
+for these values will be more meaningful if values are represented in
+MBytes and mbps. The RRDtool graph command allows to define such
+conversions. Apart from mathematical calculations, it is also possible
+to perform logical operations such as greater than, less than, and
+if/then/else. If a database contains more than one RRA archive, then a
+question may arise - how does RRDtool decide which RRA archive to use
+for retrieving the values? RRDtool looks at several things when making
+its choice. First it makes sure that the RRA covers as much of the
+graphing time frame as possible. Second it looks at the resolution of
+the RRA compared to the resolution of the graph. It tries to find one
+which has the same or higher better resolution. With the ``-r'' option
+you can force RRDtool to assume a different resolution than the one
+calculated from the pixel width of the graph.</p>
+<p>Values of different variables can be presented in 5 different shapes
+in a graph - AREA, LINE1, LINE2, LINE3, and STACK. AREA is represented
+by a solid colored area with values as the boundary of this
+area. LINE1/2/3 (increasing width) are just plain lines representing
+the values. STACK is also an area but it is ``stack''ed on top AREA or
+LINE1/2/3. Another important thing to note is that variables are
+plotted in the order they are defined in the graph command. Therefore
+care must be taken to define STACK only after defining AREA/LINE. It
+is also possible to put formatted comments within the graph.  Detailed
+instructions can be found in the graph manual.</p>

+=head1 NAME
+
+rrd-beginners - RRDtool Beginners' Guide
+
+=head1 SYNOPSIS
+
+Helping new RRDtool users to understand the basics of RRDtool
+
+=head1 DESCRIPTION
+
+This manual is an attempt to assist beginners in understanding the concepts
+of RRDtool. It sheds a light on differences between RRDtool and other
+databases. With help of an example, it explains the structure of RRDtool
+database. This is followed by an overview of the "graph" feature of RRDtool.
+At the end, it has sample scripts that illustrate the
+usage/wrapping of RRDtool within Shell or Perl scripts.
+
+=head2 What makes RRDtool so special?
+
+RRDtool is GNU licensed software developed by Tobias Oetiker, a system
+manager at the Swiss Federal Institute of Technology. Though it is a
+database, there are distinct differences between RRDtool databases and other
+databases as listed below:
+
+=over
+
+=item *
+
+RRDtool stores data; that makes it a back-end tool. The RRDtool command set
+allows the creation of graphs; that makes it a front-end tool as well. Other
+databases just store data and can not create graphs.
+
+=item *
+
+In case of linear databases, new data gets appended at the bottom of
+the database table. Thus its size keeps on increasing, whereas the size of
+an RRDtool database is determined at creation time. Imagine an RRDtool
+database as the perimeter of a circle. Data is added along the
+perimeter. When new data reaches the starting point, it overwrites
+existing data. This way, the size of an RRDtool database always
+remains constant. The name "Round Robin" stems from this behavior.
+
+=item *
+
+Other databases store the values as supplied. RRDtool can be configured to
+calculate the rate of change from the previous to the current value and
+store this information instead.
+
+=item *
+
+Other databases get updated when values are supplied. The RRDtool database
+is structured in such a way that it needs data at predefined time
+intervals. If it does not get a new value during the interval, it stores an
+UNKNOWN value for that interval. So, when using the RRDtool database, it is
+imperative to use scripts that run at regular intervals to ensure a constant
+data flow to update the RRDtool database.
+
+=back
+
+RRDtool is designed to store time series of data. With every data
+update, an associated time stamp is stored. Time is always expressed
+in seconds passed since epoch (01-01-1970). RRDtool can be installed
+on Unix as well as Windows. It comes with a command set to carry out
+various operations on RRD databases. This command set can be accessed
+from the command line, as well as from Shell or Perl scripts. The
+scripts act as wrappers for accessing data stored in RRDtool
+databases.
+
+=head2 Understanding by an example
+
+The structure of an RRD database is different than other linear databases.
+Other databases define tables with columns, and many other parameters. These
+definitions sometimes are very complex, especially in large databases.
+RRDtool databases are primarily used for monitoring purposes and
+hence are very simple in structure. The parameters
+that need to be defined are variables that hold values and archives of those
+values. Being time sensitive, a couple of time related parameters are also
+defined. Because of its structure, the definition of an RRDtool database also
+includes a provision to specify specific actions to take in the absence of
+update values. Data Source (DS), heartbeat, Date Source Type (DST), Round
+Robin Archive (RRA), and Consolidation Function (CF) are some of the
+terminologies related to RRDtool databases.
+
+The structure of a database and the terminology associated with it can be
+best explained with an example.
+
+ rrdtool create target.rrd \
+         --start 1023654125 \
+         --step 300 \
+         DS:mem:GAUGE:600:0:671744 \
+         RRA:AVERAGE:0.5:12:24 \
+         RRA:AVERAGE:0.5:288:31
+
+This example creates a database named F<target.rrd>. Start time
+(1'023'654'125) is specified in total number of seconds since epoch
+(time in seconds since 01-01-1970). While updating the database, the
+update time is also specified.  This update time MUST be large (later)
+then start time and MUST be in seconds since epoch.
+
+The step of 300 seconds indicates that database expects new values every
+300 seconds. The wrapper script should be scheduled to run every B<step>
+seconds so that it updates the database every B<step> seconds.
+
+DS (Data Source) is the actual variable which relates to the parameter on
+the device that is monitored. Its syntax is
+
+ DS:variable_name:DST:heartbeat:min:max
+
+B<DS> is a key word. C<variable_name> is a name under which the parameter is
+saved in the database. There can be as many DSs in a database as needed. After
+every step interval, a new value of DS is supplied to update the database.
+This value is also called Primary Data Point B<(PDP)>. In our example
+mentioned above, a new PDP is generated every 300 seconds.
+
+Note, that if you do NOT supply new datapoints exactly every 300 seconds,
+this is not a problem, RRDtool will interpolate the data accordingly.
+
+B<DST> (Data Source Type) defines the type of the DS. It can be
+COUNTER, DERIVE, ABSOLUTE, GAUGE. A DS declared as COUNTER will save
+the rate of change of the value over a step period. This assumes that
+the value is always increasing (the difference between the current and
+the previous value is greater than 0). Traffic counters on a router
+are an ideal candidate for using COUNTER as DST. DERIVE is the same as
+COUNTER, but it allows negative values as well. If you want to see the
+rate of I<change> in free diskspace on your server, then you might
+want to use the DERIVE data type. ABSOLUTE also saves the rate of
+change, but it assumes that the previous value is set to 0. The
+difference between the current and the previous value is always equal
+to the current value. Thus it just stores the current value divided by
+the step interval (300 seconds in our example). GAUGE does not save
+the rate of change. It saves the actual value itself. There are no
+divisions or calculations. Memory consumption in a server is a typical
+example of gauge. The difference between the different types DSTs can be
+explained better with the following example:
+
+ Values       = 300, 600, 900, 1200
+ Step         = 300 seconds
+ COUNTER DS   =    1,  1,   1,    1
+ DERIVE DS    =    1,  1,   1,    1
+ ABSOLUTE DS  =    1,  2,   3,    4
+ GAUGE DS     = 300, 600, 900, 1200
+
+The next parameter is B<heartbeat>. In our example, heartbeat is 600
+seconds. If the database does not get a new PDP within 300 seconds, it
+will wait for another 300 seconds (total 600 seconds).  If it doesn't
+receive any PDP within 600 seconds, it will save an UNKNOWN value into
+the database. This UNKNOWN value is a special feature of RRDtool - it
+is much better than to assume a missing value was 0 (zero) or any
+other number which might also be a valid data value.  For example, the
+traffic flow counter on a router keeps increasing. Lets say, a value
+is missed for an interval and 0 is stored instead of UNKNOWN. Now when
+the next value becomes available, it will calculate the difference
+between the current value and the previous value (0) which is not
+correct. So, inserting the value UNKNOWN makes much more sense here.
+
+The next two parameters are the minimum and maximum value,
+respectively. If the variable to be stored has predictable maximum and
+minimum values, this should be specified here. Any update value
+falling out of this range will be stored as UNKNOWN.
+
+The next line declares a round robin archive (RRA). The syntax for
+declaring an RRA is
+
+ RRA:CF:xff:step:rows
+
+RRA is the keyword to declare RRAs. The consolidation function (CF)
+can be AVERAGE, MINIMUM, MAXIMUM, and LAST. The concept of the
+consolidated data point (CDP) comes into the picture here. A CDP is
+CFed (averaged, maximum/minimum value or last value) from I<step>
+number of PDPs. This RRA will hold I<rows> CDPs.
+
+Lets have a look at the example above. For the first RRA, 12 (steps)
+PDPs (DS variables) are AVERAGEed (CF) to form one CDP. 24 (rows) of
+theses CDPs are archived. Each PDP occurs at 300 seconds. 12 PDPs
+represent 12 times 300 seconds which is 1 hour. It means 1 CDP (which
+is equal to 12 PDPs) represents data worth 1 hour. 24 such CDPs
+represent 1 day (1 hour times 24 CDPs). This means, this RRA is an
+archive for one day. After 24 CDPs, CDP number 25 will replace the 1st
+CDP. The second RRA saves 31 CDPs; each CPD represents an AVERAGE
+value for a day (288 PDPs, each covering 300 seconds = 24
+hours). Therefore this RRA is an archive for one month. A single
+database can have many RRAs. If there are multiple DSs, each
+individual RRA will save data for all the DSs in the database. For
+example, if a database has 3 DSs and daily, weekly, monthly, and
+yearly RRAs are declared, then each RRA will hold data from all 3 data
+sources.
+
+=head2 Graphical Magic
+
+Another important feature of RRDtool is its ability to create
+graphs. The "graph" command uses the "fetch" command internally to
+retrieve values from the database. With the retrieved values it draws
+graphs as defined by the parameters supplied on the command line. A
+single graph can show different DS (Data Sources) from a database. It
+is also possible to show the values from more than one database in a
+single graph. Often, it is necessary to perform some math on the
+values retrieved from the database before plotting them. For example,
+in SNMP replies, memory consumption values are usually specified in
+KBytes and traffic flow on interfaces is specified in Bytes. Graphs
+for these values will be more meaningful if values are represented in
+MBytes and mbps. The RRDtool graph command allows to define such
+conversions. Apart from mathematical calculations, it is also possible
+to perform logical operations such as greater than, less than, and
+if/then/else. If a database contains more than one RRA archive, then a
+question may arise - how does RRDtool decide which RRA archive to use
+for retrieving the values? RRDtool looks at several things when making
+its choice. First it makes sure that the RRA covers as much of the
+graphing time frame as possible. Second it looks at the resolution of
+the RRA compared to the resolution of the graph. It tries to find one
+which has the same or higher better resolution. With the "-r" option
+you can force RRDtool to assume a different resolution than the one
+calculated from the pixel width of the graph.
+
+Values of different variables can be presented in 5 different shapes
+in a graph - AREA, LINE1, LINE2, LINE3, and STACK. AREA is represented
+by a solid colored area with values as the boundary of this
+area. LINE1/2/3 (increasing width) are just plain lines representing
+the values. STACK is also an area but it is "stack"ed on top AREA or
+LINE1/2/3. Another important thing to note is that variables are
+plotted in the order they are defined in the graph command. Therefore
+care must be taken to define STACK only after defining AREA/LINE. It
+is also possible to put formatted comments within the graph.  Detailed
+instructions can be found in the graph manual.
+
+=head2 Wrapping RRDtool within Shell/Perl script
+
+After understanding RRDtool it is now a time to actually use RRDtool
+in scripts. Tasks involved in network management are data collection,
+data storage, and data retrieval. In the following example, the
+previously created target.rrd database is used. Data collection and
+data storage is done using Shell scripts. Data retrieval and report
+generation is done using Perl scripts. These scripts are shown below:
+
+=head3 Shell script (collects data, updates database)
+
+ #!/bin/sh
+ a=0
+ while [ "$a" == 0 ]; do
+ snmpwalk -c public 192.168.1.250 hrSWRunPerfMem > snmp_reply
+     total_mem=`awk 'BEGIN {tot_mem=0}
+                           { if ($NF == "KBytes")
+                             {tot_mem=tot_mem+$(NF-1)}
+                           }
+                     END {print tot_mem}' snmp_reply`
+     # I can use N as a replacement for the current time
+     rrdtool update target.rrd N:$total_mem
+     # sleep until the next 300 seconds are full
+     perl -e 'sleep 300 - time % 300'
+ done # end of while loop
+
+=head3 Perl script (retrieves data from database and generates graphs and statistics)
+
+ #!/usr/bin/perl -w
+ # This script fetches data from target.rrd, creates a graph of memory
+ # consumption on the target (Dual P3 Processor 1 GHz, 656 MB RAM)
+
+ # call the RRD perl module
+ use lib qw( /usr/local/rrdtool-1.0.41/lib/perl ../lib/perl );
+ use RRDs;
+ my $cur_time = time();                # set current time
+ my $end_time = $cur_time - 86400;     # set end time to 24 hours ago
+ my $start_time = $end_time - 2592000; # set start 30 days in the past
+
+ # fetch average values from the RRD database between start and end time
+ my ($start,$step,$ds_names,$data) =
+     RRDs::fetch("target.rrd", "AVERAGE",
+                 "-r", "600", "-s", "$start_time", "-e", "$end_time");
+ # save fetched values in a 2-dimensional array

+   $columns = 0;

+ my $count = 0;
+ # save the values from the 2-dimensional into a 1-dimensional array

+     $count++;
+ }
+ my $tot_mem_sum = 0;
+ # calculate the total of all values

+
+       This example creates a database named _\bt_\ba_\br_\bg_\be_\bt_\b._\br_\br_\bd. Start time
+       (1'023'654'125) is specified in total number of seconds since epoch
+       (time in seconds since 01-01-1970). While updating the database, the
+       update time is also specified.  This update time MUST be large (later)
+       then start time and MUST be in seconds since epoch.
+
+       The step of 300 seconds indicates that database expects new values
+       every 300 seconds. The wrapper script should be scheduled to run every
+       s\bst\bte\bep\bp seconds so that it updates the database every s\bst\bte\bep\bp seconds.
+
+       DS (Data Source) is the actual variable which relates to the parameter
+       on the device that is monitored. Its syntax is
+
+        DS:variable_name:DST:heartbeat:min:max
+
+       D\bDS\bS is a key word. "variable_name" is a name under which the parameter
+       is saved in the database. There can be as many DSs in a database as
+       needed. After every step interval, a new value of DS is supplied to
+       update the database.  This value is also called Primary Data Point
+       (\b(P\bPD\bDP\bP)\b). In our example mentioned above, a new PDP is generated every 300
+       seconds.
+
+       Note, that if you do NOT supply new datapoints exactly every 300 sec-
+       onds, this is not a problem, RRDtool will interpolate the data accord-
+       ingly.
+
+       D\bDS\bST\bT (Data Source Type) defines the type of the DS. It can be COUNTER,
+       DERIVE, ABSOLUTE, GAUGE. A DS declared as COUNTER will save the rate of
+       change of the value over a step period. This assumes that the value is
+       always increasing (the difference between the current and the previous
+       value is greater than 0). Traffic counters on a router are an ideal
+       candidate for using COUNTER as DST. DERIVE is the same as COUNTER, but
+       it allows negative values as well. If you want to see the rate of
+       _\bc_\bh_\ba_\bn_\bg_\be in free diskspace on your server, then you might want to use the
+       DERIVE data type. ABSOLUTE also saves the rate of change, but it
+       assumes that the previous value is set to 0. The difference between the
+       current and the previous value is always equal to the current value.
+       Thus it just stores the current value divided by the step interval (300
+       seconds in our example). GAUGE does not save the rate of change. It
+       saves the actual value itself. There are no divisions or calculations.
+       Memory consumption in a server is a typical example of gauge. The dif-
+       ference between the different types DSTs can be explained better with
+       the following example:
+
+        Values       = 300, 600, 900, 1200
+        Step         = 300 seconds
+        COUNTER DS   =    1,  1,   1,    1
+        DERIVE DS    =    1,  1,   1,    1
+        ABSOLUTE DS  =    1,  2,   3,    4
+        GAUGE DS     = 300, 600, 900, 1200
+
+       The next parameter is h\bhe\bea\bar\brt\btb\bbe\bea\bat\bt. In our example, heartbeat is 600 sec-
+       onds. If the database does not get a new PDP within 300 seconds, it
+       will wait for another 300 seconds (total 600 seconds).  If it doesn't
+       receive any PDP within 600 seconds, it will save an UNKNOWN value into
+       the database. This UNKNOWN value is a special feature of RRDtool - it
+       is much better than to assume a missing value was 0 (zero) or any other
+       number which might also be a valid data value.  For example, the traf-
+       fic flow counter on a router keeps increasing. Lets say, a value is
+       missed for an interval and 0 is stored instead of UNKNOWN. Now when the
+       next value becomes available, it will calculate the difference between
+       the current value and the previous value (0) which is not correct. So,
+       inserting the value UNKNOWN makes much more sense here.
+
+       The next two parameters are the minimum and maximum value, respec-
+       tively. If the variable to be stored has predictable maximum and mini-
+       mum values, this should be specified here. Any update value falling out
+       of this range will be stored as UNKNOWN.
+
+       The next line declares a round robin archive (RRA). The syntax for
+       declaring an RRA is
+
+        RRA:CF:xff:step:rows
+
+       RRA is the keyword to declare RRAs. The consolidation function (CF) can
+       be AVERAGE, MINIMUM, MAXIMUM, and LAST. The concept of the consolidated
+       data point (CDP) comes into the picture here. A CDP is CFed (averaged,
+       maximum/minimum value or last value) from _\bs_\bt_\be_\bp number of PDPs. This RRA
+       will hold _\br_\bo_\bw_\bs CDPs.
+
+       Lets have a look at the example above. For the first RRA, 12 (steps)
+       PDPs (DS variables) are AVERAGEed (CF) to form one CDP. 24 (rows) of
+       theses CDPs are archived. Each PDP occurs at 300 seconds. 12 PDPs rep-
+       resent 12 times 300 seconds which is 1 hour. It means 1 CDP (which is
+       equal to 12 PDPs) represents data worth 1 hour. 24 such CDPs represent
+       1 day (1 hour times 24 CDPs). This means, this RRA is an archive for
+       one day. After 24 CDPs, CDP number 25 will replace the 1st CDP. The
+       second RRA saves 31 CDPs; each CPD represents an AVERAGE value for a
+       day (288 PDPs, each covering 300 seconds = 24 hours). Therefore this
+       RRA is an archive for one month. A single database can have many RRAs.
+       If there are multiple DSs, each individual RRA will save data for all
+       the DSs in the database. For example, if a database has 3 DSs and
+       daily, weekly, monthly, and yearly RRAs are declared, then each RRA
+       will hold data from all 3 data sources.

+
+       Another important feature of RRDtool is its ability to create graphs.
+       The "graph" command uses the "fetch" command internally to retrieve
+       values from the database. With the retrieved values it draws graphs as
+       defined by the parameters supplied on the command line. A single graph
+       can show different DS (Data Sources) from a database. It is also possi-
+       ble to show the values from more than one database in a single graph.
+       Often, it is necessary to perform some math on the values retrieved
+       from the database before plotting them. For example, in SNMP replies,
+       memory consumption values are usually specified in KBytes and traffic
+       flow on interfaces is specified in Bytes. Graphs for these values will
+       be more meaningful if values are represented in MBytes and mbps. The
+       RRDtool graph command allows to define such conversions. Apart from
+       mathematical calculations, it is also possible to perform logical oper-
+       ations such as greater than, less than, and if/then/else. If a database
+       contains more than one RRA archive, then a question may arise - how
+       does RRDtool decide which RRA archive to use for retrieving the values?
+       RRDtool looks at several things when making its choice. First it makes
+       sure that the RRA covers as much of the graphing time frame as possi-
+       ble. Second it looks at the resolution of the RRA compared to the reso-
+       lution of the graph. It tries to find one which has the same or higher
+       better resolution. With the "-r" option you can force RRDtool to assume
+       a different resolution than the one calculated from the pixel width of
+       the graph.
+
+       Values of different variables can be presented in 5 different shapes in
+       a graph - AREA, LINE1, LINE2, LINE3, and STACK. AREA is represented by
+       a solid colored area with values as the boundary of this area.
+       LINE1/2/3 (increasing width) are just plain lines representing the val-
+       ues. STACK is also an area but it is "stack"ed on top AREA or
+       LINE1/2/3. Another important thing to note is that variables are plot-
+       ted in the order they are defined in the graph command. Therefore care
+       must be taken to define STACK only after defining AREA/LINE. It is also
+       possible to put formatted comments within the graph.  Detailed instruc-
+       tions can be found in the graph manual.

+
+       After understanding RRDtool it is now a time to actually use RRDtool in
+       scripts. Tasks involved in network management are data collection, data
+       storage, and data retrieval. In the following example, the previously
+       created target.rrd database is used. Data collection and data storage
+       is done using Shell scripts. Data retrieval and report generation is
+       done using Perl scripts. These scripts are shown below:
+
+       _\bS_\bh_\be_\bl_\bl _\bs_\bc_\br_\bi_\bp_\bt _\b(_\bc_\bo_\bl_\bl_\be_\bc_\bt_\bs _\bd_\ba_\bt_\ba_\b, _\bu_\bp_\bd_\ba_\bt_\be_\bs _\bd_\ba_\bt_\ba_\bb_\ba_\bs_\be_\b)

+rrdbuild \- Instructions for building RRDtool
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+.Sh "Overview"
+.IX Subsection "Overview"
+If you downloaded the source of rrdtool you have to compile it. This
+document will give some information on how this is done.
+.PP
+RRDtool relies on services of thrid part libraries. Some of these libraries
+may already be installed on your system. You have to compile copies of the other
+ones before you can build RRDtool.
+.PP
+This document will tell you about all the necessary steps to get going.
+.Sh "Building"
+.IX Subsection "Building"
+Before you start to build RRDtool, you have to decide two things:
+.IP "1." 4
+In which directory you want to build the software.
+.IP "2." 4
+Where you want to install the software.
+.PP
+Once you have decided. Save the two locations into environment variables.
+Depending on the shell you are using, you can do either (bash,zsh):
+.PP
+.Vb 2
+\& BUILD_DIR=/tmp/rrdbuild
+\& INSTALL_DIR=/usr/local/rrdtool\-1.2.26
+.Ve
+.PP
+Or if you run tcsh:
+.PP
+.Vb 2
+\& set BUILD_DIR=/tmp/rrdbuild
+\& set INSTALL_DIR=/usr/local/rrdtool\-1.2.26
+.Ve
+.PP
+If your \fI/tmp\fR is mounted with the option noexec (\s-1RHEL\s0 seems todo that) you have to choose
+a different directory!
+.PP
+Now make sure the \s-1BUILD_DIR\s0 exists and go there:
+.PP
+.Vb 2
+\& mkdir \-p $BUILD_DIR
+\& cd $BUILD_DIR
+.Ve
+.PP
+Lets first assume you already have all the necessary libraries
+pre\-installed. Note that these instructions assume that your copies of
+\&\fBtar\fR and \fBmake\fR are actually \fB\s-1GNU\s0 tar\fR and \fB\s-1GNU\s0 make\fR respectively. It
+could be that they are installed as \fBgtar\fR and \fBgmake\fR on your system.
+.PP
+.Vb 4
+\& wget http://oss.oetiker.ch/rrdtool/pub/rrdtool\-1.2.26.tar.gz
+\& tar zxf rrdtool\-1.2.26.tar.gz
+\& cd rrdtool\-1.2.26
+\& ./configure \-\-prefix=$INSTALL_DIR && make && make install
+.Ve
+.PP
+Ok, this was very optimistic. This try will probably have ended with
+\&\fBconfigure\fR complaining about several missing libraries. If you are on a
+Linux or *bsd system you may want to just install the missing bits from your
+software repository. When you do that, make sure you also get the \fB\-dev\fR
+package for each library you install. Once you have the missing bits on
+board, just re-run the last line of the instructions above.
+.PP
+But again this may have been too optimistic, and you actually have to
+compile your own copies of the required libraries.
+.PP
+\fIBuild Tipps for \s-1AIX\s0\fR
+.IX Subsection "Build Tipps for AIX"
+.PP
+If you are woking with \s-1AIX\s0, you may find the the \fB\-\-disable\-shared\fR option
+will cause things to break for you. In that case you may have to install the
+shared libraries into the rrdtool \s-1PREFIX\s0 and work with \fB\-\-disable\-static\fR
+instead.
+.PP
+Another hint to get rrdtool working on \s-1AIX\s0 is to use the \s-1IBM\s0 \s-1XL\s0 C Compiler:
+.PP
+.Vb 2
+\& export CC=/usr/vac/bin/cc
+\& export PERLCC=$CC
+.Ve
+.PP
+(Better instructions for \s-1AIX\s0 welcome!)
+.Sh "Building Libraries"
+.IX Subsection "Building Libraries"
+In order to build the libraries you need a compiler on your system.
+Unfortunately compilers are not all alike. This has an effect on the \s-1CFLAGS\s0
+you want to set. The examples below are for the popular \s-1GCC\s0 compiler suite.
+If you have an other compile you have to use the following settings:
+.IP "Sun Forte" 4
+.IX Item "Sun Forte"
+.Vb 1
+\& CFLAGS="\-xO3 \-kPIC"
+.Ve
+.IP "Building zlib" 4
+.IX Item "Building zlib"
+.Vb 7
+\& cd $BUILD_DIR
+\& wget http://oss.oetiker.ch/rrdtool/pub/libs/zlib\-1.2.3.tar.gz
+\& tar  zxf zlib\-1.2.3.tar.gz
+\& cd zlib\-1.2.3
+\& env CFLAGS="\-O3 \-fPIC" ./configure \-\-prefix=$BUILD_DIR/lb
+\& make
+\& make install
+.Ve
+.IP "Building libpng" 4
+.IX Item "Building libpng"
+Libpng itself requires zlib to build, so we need to help a bit. If you
+already have a copy of zlib on your system (which is very likley) you can
+drop the settings of \s-1LDFLAGS\s0 and \s-1CPPFLAGS\s0. Note that the backslash (\e) at
+the end of line 4 means that line 4 and line 5 are on one line.
+.Sp
+.Vb 8
+\& cd $BUILD_DIR
+\& wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng\-1.2.10.tar.gz
+\& tar zxvf libpng\-1.2.10.tar.gz
+\& cd libpng\-1.2.10
+\& env CPPFLAGS="\-I$BUILD_DIR/lb/include" LDFLAGS="\-L$BUILD_DIR/lb/lib" CFLAGS="\-O3 \-fPIC" \e
+\&     ./configure \-\-disable\-shared \-\-prefix=$BUILD_DIR/lb
+\& make
+\& make install
+.Ve
+.IP "Building freetype" 4
+.IX Item "Building freetype"
+.Vb 8
+\& cd $BUILD_DIR
+\& wget http://oss.oetiker.ch/rrdtool/pub/libs/freetype\-2.1.10.tar.bz2
+\& tar jxvf freetype\-2.1.10.tar.bz2
+\& cd freetype\-2.1.10
+\& env CPPFLAGS="\-I$BUILD_DIR/lb/include" LDFLAGS="\-L$BUILD_DIR/lb/lib" CFLAGS="\-O3 \-fPIC" \e
+\&     ./configure \-\-disable\-shared \-\-prefix=$BUILD_DIR/lb
+\& make
+\& make install
+.Ve
+.Sp
+If you run into problems building freetype on Solaris, you may want to try to
+add the following at the end of the configure line:
+.Sp
+.Vb 1
+\& GNUMAKE=gmake EGREP=egrep
+.Ve
+.IP "Building libart_lgpl" 4
+.IX Item "Building libart_lgpl"
+.Vb 7
+\& cd $BUILD_DIR
+\& wget http://oss.oetiker.ch/rrdtool/pub/libs/libart_lgpl\-2.3.17.tar.gz
+\& tar zxvf libart_lgpl\-2.3.17.tar.gz
+\& cd libart_lgpl\-2.3.17
+\& env CFLAGS="\-O3 \-fPIC" ./configure \-\-disable\-shared \-\-prefix=$BUILD_DIR/lb
+\& make
+\& make install
+.Ve
+.PP
+Now all the dependent libraries are built and you can try again. Since these
+are static libraries, you may have to use \fIranlib\fR to make them accessible.
+Especially \s-1BSD\s0 systems like Mac \s-1OS\s0 X may require this, Linux and Solaris
+will do just fine without since their \fIar\fR command does ranlibs job as well.
+.PP
+.Vb 1
+\& ranlib $BUILD_DIR/lb/lib/*.a
+.Ve
+.PP
+This time you tell configure where it should be looking for libraries and
+include files. This is done via environment variables. Depending on the
+shell you are running, the syntax for setting environment variables is
+different. Under csh/tcsh you use:
+.PP
+.Vb 4
+\& set IR=\-I$BUILD_DIR/lb/include
+\& setenv CPPFLAGS "$IR $IR/libart\-2.0 $IR/freetype2 $IR/libpng"
+\& setenv LDFLAGS  \-L$BUILD_DIR/lb/lib
+\& setenv CFLAGS \-O3
+.Ve
+.PP
+If you are running bash/sh/ash/ksh/zsh use this:
+.PP
+.Vb 5
+\& IR=\-I$BUILD_DIR/lb/include
+\& CPPFLAGS="$IR $IR/libart\-2.0 $IR/freetype2 $IR/libpng"
+\& LDFLAGS="\-L$BUILD_DIR/lb/lib"
+\& CFLAGS=\-O3
+\& export CPPFLAGS LDFLAGS CFLAGS
+.Ve
+.PP
+And finally try building again. We disable the python and tcl bindings
+because it seems that a fair number of people have ill configured python and
+tcl setups that would prevent rrdtool from building if they are included in
+their current state.
+.PP
+.Vb 5
+\& cd $BUILD_DIR/rrdtool\-1.2.26
+\& ./configure \-\-prefix=$INSTALL_DIR \-\-disable\-python \-\-disable\-tcl
+\& make clean
+\& make
+\& make install
+.Ve
+.PP
+\&\s-1SOLARIS\s0 \s-1HINT:\s0 if you want to build  the perl module for the native perl (the
+one shipping with solaris) you will need the sun forte compiler
+installed on your box or you have to hand-tune bindings/perl\-shared/Makefile
+while building!
+.PP
+Now go to \fI$INSTALL_DIR\fR\fB/share/rrdtool/examples/\fR and run them to see if your
+build has been successful.

+Where you want to install the software.
+

+
+Once you have decided. Save the two locations into environment variables.
+Depending on the shell you are using, you can do either (bash,zsh):

+If your F</tmp> is mounted with the option noexec (RHEL seems todo that) you have to choose
+a different directory!
+
+Now make sure the BUILD_DIR exists and go there:
+
+ mkdir -p $BUILD_DIR
+ cd $BUILD_DIR
+
+Lets first assume you already have all the necessary libraries
+pre-installed. Note that these instructions assume that your copies of
+B<tar> and B<make> are actually B<GNU tar> and B<GNU make> respectively. It

+
+And finally try building again. We disable the python and tcl bindings

+
+       If you downloaded the source of rrdtool you have to compile it. This
+       document will give some information on how this is done.
+
+       RRDtool relies on services of thrid part libraries. Some of these
+       libraries may already be installed on your system. You have to compile
+       copies of the other ones before you can build RRDtool.
+
+       This document will tell you about all the necessary steps to get going.
+
+       B\bBu\bui\bil\bld\bdi\bin\bng\bg
+
+       Before you start to build RRDtool, you have to decide two things:
+
+       1.  In which directory you want to build the software.
+
+       2.  Where you want to install the software.
+
+       Once you have decided. Save the two locations into environment vari-
+       ables.  Depending on the shell you are using, you can do either
+       (bash,zsh):
+
+        BUILD_DIR=/tmp/rrdbuild
+        INSTALL_DIR=/usr/local/rrdtool-1.2.26
+
+       Or if you run tcsh:
+
+        set BUILD_DIR=/tmp/rrdbuild
+        set INSTALL_DIR=/usr/local/rrdtool-1.2.26
+
+       If your _\b/_\bt_\bm_\bp is mounted with the option noexec (RHEL seems todo that)
+       you have to choose a different directory!
+
+       Now make sure the BUILD_DIR exists and go there:
+
+        mkdir -p $BUILD_DIR
+        cd $BUILD_DIR
+
+       Lets first assume you already have all the necessary libraries
+       pre-installed. Note that these instructions assume that your copies of
+       t\bta\bar\br and m\bma\bak\bke\be are actually G\bGN\bNU\bU t\bta\bar\br and G\bGN\bNU\bU m\bma\bak\bke\be respectively. It could
+       be that they are installed as g\bgt\bta\bar\br and g\bgm\bma\bak\bke\be on your system.
+
+        wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.26.tar.gz
+        tar zxf rrdtool-1.2.26.tar.gz
+        cd rrdtool-1.2.26
+        ./configure --prefix=$INSTALL_DIR && make && make install
+
+       Ok, this was very optimistic. This try will probably have ended with
+       c\bco\bon\bnf\bfi\big\bgu\bur\bre\be complaining about several missing libraries. If you are on a
+       Linux or *bsd system you may want to just install the missing bits from
+       your software repository. When you do that, make sure you also get the
+       -\b-d\bde\bev\bv package for each library you install. Once you have the missing
+       bits on board, just re-run the last line of the instructions above.
+
+       But again this may have been too optimistic, and you actually have to
+       compile your own copies of the required libraries.
+
+       _\bB_\bu_\bi_\bl_\bd _\bT_\bi_\bp_\bp_\bs _\bf_\bo_\br _\bA_\bI_\bX
+
+       If you are woking with AIX, you may find the the -\b--\b-d\bdi\bis\bsa\bab\bbl\ble\be-\b-s\bsh\bha\bar\bre\bed\bd
+       option will cause things to break for you. In that case you may have to
+       install the shared libraries into the rrdtool PREFIX and work with
+       -\b--\b-d\bdi\bis\bsa\bab\bbl\ble\be-\b-s\bst\bta\bat\bti\bic\bc instead.
+
+       Another hint to get rrdtool working on AIX is to use the IBM XL C Com-
+       piler:
+
+        export CC=/usr/vac/bin/cc
+        export PERLCC=$CC
+
+       (Better instructions for AIX welcome!)
+
+       B\bBu\bui\bil\bld\bdi\bin\bng\bg L\bLi\bib\bbr\bra\bar\bri\bie\bes\bs
+
+       In order to build the libraries you need a compiler on your system.
+       Unfortunately compilers are not all alike. This has an effect on the
+       CFLAGS you want to set. The examples below are for the popular GCC com-
+       piler suite.  If you have an other compile you have to use the follow-
+       ing settings:
+
+       Sun Forte
+            CFLAGS="-xO3 -kPIC"
+
+       Building zlib
+            cd $BUILD_DIR
+            wget http://oss.oetiker.ch/rrdtool/pub/libs/zlib-1.2.3.tar.gz
+            tar  zxf zlib-1.2.3.tar.gz
+            cd zlib-1.2.3
+            env CFLAGS="-O3 -fPIC" ./configure --prefix=$BUILD_DIR/lb
+            make
+            make install
+
+       Building libpng
+           Libpng itself requires zlib to build, so we need to help a bit. If
+           you already have a copy of zlib on your system (which is very lik-
+           ley) you can drop the settings of LDFLAGS and CPPFLAGS. Note that
+           the backslash (\) at the end of line 4 means that line 4 and line 5
+           are on one line.
+
+            cd $BUILD_DIR
+            wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.10.tar.gz

+                ./configure --disable-shared --prefix=$BUILD_DIR/lb
+            make
+            make install
+
+           If you run into problems building freetype on Solaris, you may want
+           to try to add the following at the end of the configure line:
+
+            GNUMAKE=gmake EGREP=egrep

+            make
+            make install
+
+       Now all the dependent libraries are built and you can try again. Since
+       these are static libraries, you may have to use _\br_\ba_\bn_\bl_\bi_\bb to make them
+       accessible.  Especially BSD systems like Mac OS X may require this,

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBrrdcgi\fR is a sort of very limited script interpreter. Its purpose
+is to run as a cgi-program and parse a web page template containing special
+<\s-1RRD::\s0 tags. \fBrrdcgi\fR will interpret and act according to these tags.
+In the end it will printout a web page including the necessary \s-1CGI\s0 headers.
+.PP
+\&\fBrrdcgi\fR parses the contents of the template in 3 steps. In each step it looks
+only for a subset of tags. This allows nesting of tags.
+.PP
+The argument parser uses the same semantics as you are used from your C\-shell.
+.IP "\fB\-\-filter\fR" 8

+Inserts the \s-1CGI\s0 variable of the given name.
+.IP "\s-1RRD::CV::QUOTE\s0 \fIname\fR" 8
+.IX Item "RRD::CV::QUOTE name"
+Inserts the \s-1CGI\s0 variable of the given name but quotes it, ready for
+use as an argument in another \s-1RRD::\s0 tag. So even when there are spaces in the
+value of the \s-1CGI\s0 variable it will still be considered to be one argument.
+.IP "\s-1RRD::CV::PATH\s0 \fIname\fR" 8
+.IX Item "RRD::CV::PATH name"
+Inserts the \s-1CGI\s0 variable of the given name, quotes it and makes sure
+it starts neither with a '/' nor contains '..'. This is to make
+sure that no problematic pathnames can be introduced through the
+\&\s-1CGI\s0 interface.

+
+=head1 DESCRIPTION
+
+B<rrdcgi> is a sort of very limited script interpreter. Its purpose
+is to run as a cgi-program and parse a web page template containing special
+E<lt>RRD:: tags. B<rrdcgi> will interpret and act according to these tags.
+In the end it will printout a web page including the necessary CGI headers.
+
+B<rrdcgi> parses the contents of the template in 3 steps. In each step it looks

+
+The argument parser uses the same semantics as you are used from your C-shell.
+
+=over 8
+
+=item B<--filter>
+
+Assume that rrdcgi is run as a filter and not as a cgi.
+
+=back
+
+=head2 Keywords
+
+=over 8
+
+=item RRD::CV I<name>
+
+Inserts the CGI variable of the given name.
+
+=item RRD::CV::QUOTE I<name>
+
+Inserts the CGI variable of the given name but quotes it, ready for
+use as an argument in another RRD:: tag. So even when there are spaces in the
+value of the CGI variable it will still be considered to be one argument.
+
+=item RRD::CV::PATH I<name>
+
+Inserts the CGI variable of the given name, quotes it and makes sure
+it starts neither with a '/' nor contains '..'. This is to make
+sure that no problematic pathnames can be introduced through the
+CGI interface.
+
+=item RRD::GETENV I<variable>
+
+Get the value of an environment variable.
+
+ <RRD::GETENV REMOTE_USER>
+
+might give you the name of the remote user given you are using
+some sort of access control on the directory.
+
+
+=item RRD::GOODFOR I<seconds>
+
+Specify the number of seconds this page should remain valid. This will prompt
+the rrdcgi to output a Last-Modified, an Expire and if the number of
+seconds is I<negative> a Refresh header.
+
+=item RRD::INCLUDE I<filename>
+
+Include the contents of the specified file into the page returned from the cgi.
+
+=item RRD::SETENV I<variable> I<value>
+
+If you want to present your graphs in another time zone than your own, you
+could use
+
+ <RRD::SETENV TZ UTC>
+
+to make sure everything is presented in Universal Time. Note that the
+values permitted to TZ depend on your OS.
+
+=item RRD::SETVAR I<variable> I<value>
+
+Analog to SETENV but for local variables.
+
+=item RRD::GETVAR I<variable>
+
+Analog to GETENV but for local variables.
+
+=item RRD::TIME::LAST I<rrd-file> I<strftime-format>
+
+This gets replaced by the last modification time of the selected RRD. The
+time is I<strftime>-formatted with the string specified in the second argument.
+
+=item RRD::TIME::NOW I<strftime-format>
+
+This gets replaced by the current time of day. The time is
+I<strftime>-formatted with the string specified in the argument.
+
+Note that if you return : (colons) from your strftime format you may
+have to escape them using \ if the time is to be used as an argument
+to a GRAPH command.
+
+=item RRD::TIME::STRFTIME I<START|END> I<start-spec> I<end-spec> I<strftime-format>
+
+This gets replaced by a strftime-formatted time using the format
+I<strftime-format> on either I<start-spec> or I<end-spec> depending on
+whether I<START> or I<END> is specified.  Both I<start-spec> and I<end-spec>
+must be supplied as either could be relative to the other.  This is intended
+to allow pretty titles on graphs with times that are easier for non RRDtool
+folks to figure out than "-2weeks".
+
+Note that again, if you return : (colon) from your strftime format,
+you may have to escape them using \ if the time is to be used as an

+=item RRD::GRAPH I<rrdgraph arguments>
+
+This tag creates the RRD graph defined by its argument and then is
+replaced by an appropriate E<lt>IMG ... E<gt> tag referring to the graph.
+The B<--lazy> option in RRD graph can be used to make sure that graphs
+are only regenerated when they are out of date. The arguments
+to the B<RRD::GRAPH> tag work as described in the B<rrdgraph> manual page.
+
+Use the B<--lazy> option in your RRD::GRAPH tags, to reduce the load
+on your server. This option makes sure that graphs are only regenerated when
+the old ones are out of date.
+
+If you do not specify your own B<--imginfo> format, the following will
+be used:
+
+ <IMG SRC="%s" WIDTH="%lu" HEIGHT="%lu">
+
+Note that %s stands for the filename part of the graph generated, all
+directories given in the PNG file argument will get dropped.
+
+=item RRD::PRINT I<number>
+
+If the preceding  B<RRD::GRAPH> tag contained and B<PRINT> arguments,
+then you can access their output with this tag. The I<number> argument refers to the
+number of the B<PRINT> argument. This first B<PRINT> has I<number> 0.
+
+=item RRD::INTERNAL <var>
+
+This tag gets replaced by an internal var. Currently these vars are known:
+VERSION, COMPILETIME.
+These vars represent the compiled-in values.

+       rrdcgi - Create web pages containing RRD graphs based on templates
+
+S\bSY\bYN\bNO\bOP\bPS\bSI\bIS\bS
+       "#!/path/to/"r\brr\brd\bdc\bcg\bgi\bi [-\b--\b-f\bfi\bil\blt\bte\ber\br]
+
+D\bDE\bES\bSC\bCR\bRI\bIP\bPT\bTI\bIO\bON\bN
+       r\brr\brd\bdc\bcg\bgi\bi is a sort of very limited script interpreter. Its purpose is to
+       run as a cgi-program and parse a web page template containing special
+       <RRD:: tags. r\brr\brd\bdc\bcg\bgi\bi will interpret and act according to these tags.  In
+       the end it will printout a web page including the necessary CGI head-
+       ers.
+
+       r\brr\brd\bdc\bcg\bgi\bi parses the contents of the template in 3 steps. In each step it
+       looks only for a subset of tags. This allows nesting of tags.
+
+       The argument parser uses the same semantics as you are used from your
+       C-shell.
+
+       -\b--\b-f\bfi\bil\blt\bte\ber\br
+               Assume that rrdcgi is run as a filter and not as a cgi.
+
+       K\bKe\bey\byw\bwo\bor\brd\bds\bs
+
+
+       RRD::CV _\bn_\ba_\bm_\be
+               Inserts the CGI variable of the given name.
+
+       RRD::CV::QUOTE _\bn_\ba_\bm_\be
+               Inserts the CGI variable of the given name but quotes it, ready
+               for use as an argument in another RRD:: tag. So even when there
+               are spaces in the value of the CGI variable it will still be
+               considered to be one argument.
+
+       RRD::CV::PATH _\bn_\ba_\bm_\be
+               Inserts the CGI variable of the given name, quotes it and makes
+               sure it starts neither with a '/' nor contains '..'. This is to
+               make sure that no problematic pathnames can be introduced
+               through the CGI interface.
+
+       RRD::GETENV _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be
+               Get the value of an environment variable.
+
+                <RRD::GETENV REMOTE_USER>
+
+               might give you the name of the remote user given you are using
+               some sort of access control on the directory.
+
+       RRD::GOODFOR _\bs_\be_\bc_\bo_\bn_\bd_\bs
+               Specify the number of seconds this page should remain valid.
+               This will prompt the rrdcgi to output a Last-Modified, an
+               Expire and if the number of seconds is _\bn_\be_\bg_\ba_\bt_\bi_\bv_\be a Refresh
+               header.
+
+       RRD::INCLUDE _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
+               Include the contents of the specified file into the page
+               returned from the cgi.
+
+       RRD::SETENV _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be _\bv_\ba_\bl_\bu_\be
+               If you want to present your graphs in another time zone than
+               your own, you could use
+
+                <RRD::SETENV TZ UTC>
+
+               to make sure everything is presented in Universal Time. Note
+               that the values permitted to TZ depend on your OS.
+
+       RRD::SETVAR _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be _\bv_\ba_\bl_\bu_\be
+               Analog to SETENV but for local variables.
+
+       RRD::GETVAR _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be
+               Analog to GETENV but for local variables.
+
+       RRD::TIME::LAST _\br_\br_\bd_\b-_\bf_\bi_\bl_\be _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be_\b-_\bf_\bo_\br_\bm_\ba_\bt
+               This gets replaced by the last modification time of the
+               selected RRD. The time is _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be-formatted with the string
+               specified in the second argument.
+
+       RRD::TIME::NOW _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be_\b-_\bf_\bo_\br_\bm_\ba_\bt
+               This gets replaced by the current time of day. The time is
+               _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be-formatted with the string specified in the argument.
+
+               Note that if you return : (colons) from your strftime format
+               you may have to escape them using \ if the time is to be used
+               as an argument to a GRAPH command.
+
+       RRD::TIME::STRFTIME _\bS_\bT_\bA_\bR_\bT_\b|_\bE_\bN_\bD _\bs_\bt_\ba_\br_\bt_\b-_\bs_\bp_\be_\bc _\be_\bn_\bd_\b-_\bs_\bp_\be_\bc _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be_\b-_\bf_\bo_\br_\bm_\ba_\bt
+               This gets replaced by a strftime-formatted time using the for-
+               mat _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be_\b-_\bf_\bo_\br_\bm_\ba_\bt on either _\bs_\bt_\ba_\br_\bt_\b-_\bs_\bp_\be_\bc or _\be_\bn_\bd_\b-_\bs_\bp_\be_\bc depending
+               on whether _\bS_\bT_\bA_\bR_\bT or _\bE_\bN_\bD is specified.  Both _\bs_\bt_\ba_\br_\bt_\b-_\bs_\bp_\be_\bc and _\be_\bn_\bd_\b-
+               _\bs_\bp_\be_\bc must be supplied as either could be relative to the other.
+               This is intended to allow pretty titles on graphs with times
+               that are easier for non RRDtool folks to figure out than
+               "-2weeks".
+
+               Note that again, if you return : (colon) from your strftime
+               format, you may have to escape them using \ if the time is to
+               be used as an argument to a GRAPH command.
+
+       RRD::GRAPH _\br_\br_\bd_\bg_\br_\ba_\bp_\bh _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs
+               This tag creates the RRD graph defined by its argument and then
+               is replaced by an appropriate <IMG ... > tag referring to the
+               graph.  The -\b--\b-l\bla\baz\bzy\by option in RRD graph can be used to make sure
+               that graphs are only regenerated when they are out of date. The
+               arguments to the R\bRR\bRD\bD:\b::\b:G\bGR\bRA\bAP\bPH\bH tag work as described in the r\brr\brd\bd-\b-
+               g\bgr\bra\bap\bph\bh manual page.
+
+               Use the -\b--\b-l\bla\baz\bzy\by option in your RRD::GRAPH tags, to reduce the
+               load on your server. This option makes sure that graphs are
+               only regenerated when the old ones are out of date.
+
+               If you do not specify your own -\b--\b-i\bim\bmg\bgi\bin\bnf\bfo\bo format, the following
+               will be used:
+
+                <IMG SRC="%s" WIDTH="%lu" HEIGHT="%lu">
+
+               Note that %s stands for the filename part of the graph gener-
+               ated, all directories given in the PNG file argument will get
+               dropped.
+
+       RRD::PRINT _\bn_\bu_\bm_\bb_\be_\br
+               If the preceding  R\bRR\bRD\bD:\b::\b:G\bGR\bRA\bAP\bPH\bH tag contained and P\bPR\bRI\bIN\bNT\bT arguments,
+               then you can access their output with this tag. The _\bn_\bu_\bm_\bb_\be_\br
+               argument refers to the number of the P\bPR\bRI\bIN\bNT\bT argument. This first
+               P\bPR\bRI\bIN\bNT\bT has _\bn_\bu_\bm_\bb_\be_\br 0.
+
+       RRD::INTERNAL <var>
+               This tag gets replaced by an internal var. Currently these vars
+               are known: VERSION, COMPILETIME.  These vars represent the
+               compiled-in values.

+The create function of RRDtool lets you set up new Round Robin
+Database (\fB\s-1RRD\s0\fR) files.  The file is created at its final, full size
+and filled with \fI*UNKNOWN*\fR data.
+.IP "\fIfilename\fR" 8
+.IX Item "filename"
+The name of the \fB\s-1RRD\s0\fR you want to create. \fB\s-1RRD\s0\fR files should end
+with the extension \fI.rrd\fR. However, \fBRRDtool\fR will accept any

+Specifies the time in seconds since 1970\-01\-01 \s-1UTC\s0 when the first

+any data timed before or at the time specified.

+See also AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0 section in the

+.IX Item "DS:ds-name:DST:dst arguments"
+A single \fB\s-1RRD\s0\fR can accept input from several data sources (\fB\s-1DS\s0\fR),
+for example incoming and outgoing traffic on a specific communication
+line. With the \fB\s-1DS\s0\fR configuration option you must define some basic
+properties of each data source you want to store in the \fB\s-1RRD\s0\fR.
+.Sp
+\&\fIds-name\fR is the name you will use to reference this particular data
+source from an \fB\s-1RRD\s0\fR. A \fIds-name\fR must be 1 to 19 characters long in
+the characters [a\-zA\-Z0\-9_].
+.Sp
+\&\fI\s-1DST\s0\fR defines the Data Source Type. The remaining arguments of a
+data source entry depend on the data source type. For \s-1GAUGE\s0, \s-1COUNTER\s0,

+value of a RedHat share.
+.IP "\fB\s-1COUNTER\s0\fR" 4
+.IX Item "COUNTER"
+is for continuous incrementing counters like the ifInOctets counter in
+a router. The \fB\s-1COUNTER\s0\fR data source assumes that the counter never
+decreases, except when a counter overflows.  The update function takes
+the overflow into account.  The counter is stored as a per-second
+rate. When the counter overflows, RRDtool checks if the overflow
+happened at the 32bit or 64bit border and acts accordingly by adding
+an appropriate value to the result.
+.IP "\fB\s-1DERIVE\s0\fR" 4
+.IX Item "DERIVE"
+will store the derivative of the line going from the last to the
+current value of the data source. This can be useful for gauges, for
+example, to measure the rate of people entering or leaving a
+room. Internally, derive works exactly like \s-1COUNTER\s0 but without
+overflow checks. So if your counter does not reset at 32 or 64 bit you
+might want to use \s-1DERIVE\s0 and combine it with a \s-1MIN\s0 value of 0.

+by Don Baarda <don.baarda@baesystems.com>
+.Sp
+If you cannot tolerate ever mistaking the occasional counter reset for a
+legitimate counter wrap, and would prefer \*(L"Unknowns\*(R" for all legitimate
+counter wraps and resets, always use \s-1DERIVE\s0 with min=0. Otherwise, using
+\&\s-1COUNTER\s0 with a suitable max will return correct values for all legitimate
+counter wraps, mark some counter resets as \*(L"Unknown\*(R", but can mistake some
+counter resets for a legitimate counter wrap.
+.Sp
+For a 5 minute step and 32\-bit counter, the probability of mistaking a
+counter reset for a legitimate wrap is arguably about 0.8% per 1Mbps of
+maximum bandwidth. Note that this equates to 80% for 100Mbps interfaces, so
+for high bandwidth interfaces and a 32bit counter, \s-1DERIVE\s0 with min=0 is
+probably preferable. If you are using a 64bit counter, just about any max
+setting will eliminate the possibility of mistaking a reset for a counter
+wrap.
+.RE
+.RS 4
+.RE
+.IP "\fB\s-1ABSOLUTE\s0\fR" 4
+.IX Item "ABSOLUTE"
+is for counters which get reset upon reading. This is used for fast counters
+which tend to overflow. So instead of reading them normally you reset them
+after every read to make sure you have a maximum time available before the
+next overflow. Another usage is for things you count like number of messages
+since the last update.
+.IP "\fB\s-1COMPUTE\s0\fR" 4
+.IX Item "COMPUTE"
+is for storing the result of a formula applied to other data sources
+in the \fB\s-1RRD\s0\fR. This data source is not supplied a value on update, but
+rather its Primary Data Points (PDPs) are computed from the PDPs of
+the data sources according to the rpn-expression that defines the
+formula. Consolidation functions are then applied normally to the PDPs
+of the \s-1COMPUTE\s0 data source (that is the rpn-expression is only applied
+to generate PDPs). In database software, such data sets are referred
+to as \*(L"virtual\*(R" or \*(L"computed\*(R" columns.

+\&\fImin\fR and \fImax\fR define the expected range values for data supplied by a
+data source. If \fImin\fR and/or \fImax\fR any value outside the defined range
+will be regarded as \fI*UNKNOWN*\fR. If you do not know or care about min and
+max, set them to U for unknown. Note that min and max always refer to the
+processed values of the \s-1DS\s0. For a traffic\-\fB\s-1COUNTER\s0\fR type \s-1DS\s0 this would be
+the maximum and minimum data-rate expected from the device.
+.Sp
+\&\fIIf information on minimal/maximal expected values is available,
+always set the min and/or max properties. This will help RRDtool in
+doing a simple sanity check on the data supplied when running update.\fR
+.Sp
+\&\fIrpn-expression\fR defines the formula used to compute the PDPs of a
+\&\s-1COMPUTE\s0 data source from other data sources in the same <\s-1RRD\s0>. It is
+similar to defining a \fB\s-1CDEF\s0\fR argument for the graph command. Please
+refer to that manual page for a list and description of \s-1RPN\s0 operations
+supported. For \s-1COMPUTE\s0 data sources, the following \s-1RPN\s0 operations are
+not supported: \s-1COUNT\s0, \s-1PREV\s0, \s-1TIME\s0, and \s-1LTIME\s0. In addition, in defining
+the \s-1RPN\s0 expression, the \s-1COMPUTE\s0 data source may only refer to the
+names of data source listed previously in the create command. This is
+similar to the restriction that \fB\s-1CDEF\s0\fRs must refer only to \fB\s-1DEF\s0\fRs
+and \fB\s-1CDEF\s0\fRs previously defined in the same graph command.

+.IX Item "RRA:CF:cf arguments"
+The purpose of an \fB\s-1RRD\s0\fR is to store data in the round robin archives
+(\fB\s-1RRA\s0\fR). An archive consists of a number of data values or statistics for
+each of the defined data-sources (\fB\s-1DS\s0\fR) and is defined with an \fB\s-1RRA\s0\fR line.
+.Sp
+When data is entered into an \fB\s-1RRD\s0\fR, it is first fit into time slots
+of the length defined with the \fB\-s\fR option, thus becoming a \fIprimary
+data point\fR.
+.Sp
+The data is also processed with the consolidation function (\fI\s-1CF\s0\fR) of
+the archive. There are several consolidation functions that
+consolidate primary data points via an aggregate function: \fB\s-1AVERAGE\s0\fR,
+\&\fB\s-1MIN\s0\fR, \fB\s-1MAX\s0\fR, \fB\s-1LAST\s0\fR. The format of \fB\s-1RRA\s0\fR line for these
+consolidation functions is:

+.Sp
+\&\fIxff\fR The xfiles factor defines what part of a consolidation interval may
+be made up from \fI*UNKNOWN*\fR data while the consolidated value is still
+regarded as known. It is given as the ratio of allowed \fI*UNKNOWN*\fR PDPs
+to the number of PDPs in the interval. Thus, it ranges from 0 to 1 (exclusive).
+.Sp
+\&\fIsteps\fR defines how many of these \fIprimary data points\fR are used to build
+a \fIconsolidated data point\fR which then goes into the archive.

+.PP
+These \fBRRAs\fR differ from the true consolidation functions in several ways.
+First, each of the \fB\s-1RRA\s0\fRs is updated once for every primary data point.
+Second, these \fBRRAs\fR are interdependent. To generate real-time confidence
+bounds, a matched set of \s-1HWPREDICT\s0, \s-1SEASONAL\s0, \s-1DEVSEASONAL\s0, and
+\&\s-1DEVPREDICT\s0 must exist. Generating smoothed values of the primary data points
+requires both a \s-1HWPREDICT\s0 \fB\s-1RRA\s0\fR and \s-1SEASONAL\s0 \fB\s-1RRA\s0\fR. Aberrant behavior
+detection requires \s-1FAILURES\s0, \s-1HWPREDICT\s0, \s-1DEVSEASONAL\s0, and \s-1SEASONAL\s0.
+.PP
+The actual predicted, or smoothed, values are stored in the \s-1HWPREDICT\s0
+\&\fB\s-1RRA\s0\fR. The predicted deviations are stored in \s-1DEVPREDICT\s0 (think a standard
+deviation which can be scaled to yield a confidence band). The \s-1FAILURES\s0
+\&\fB\s-1RRA\s0\fR stores binary indicators. A 1 marks the indexed observation as
+failure; that is, the number of confidence bounds violations in the
+preceding window of observations met or exceeded a specified threshold. An
+example of using these \fBRRAs\fR to graph confidence bounds and failures
+appears in rrdgraph.
+.PP
+The \s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 \fBRRAs\fR store the seasonal coefficients for the
+Holt-Winters forecasting algorithm and the seasonal deviations, respectively.
+There is one entry per observation time point in the seasonal cycle. For
+example, if primary data points are generated every five minutes and the
+seasonal cycle is 1 day, both \s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 will have 288 rows.
+.PP
+In order to simplify the creation for the novice user, in addition to
+supporting explicit creation of the \s-1HWPREDICT\s0, \s-1SEASONAL\s0, \s-1DEVPREDICT\s0,
+\&\s-1DEVSEASONAL\s0, and \s-1FAILURES\s0 \fBRRAs\fR, the \fBRRDtool\fR create command supports
+implicit creation of the other four when \s-1HWPREDICT\s0 is specified alone and
+the final argument \fIrra-num\fR is omitted.
+.PP
+\&\fIrows\fR specifies the length of the \fB\s-1RRA\s0\fR prior to wrap around. Remember
+that there is a one-to-one correspondence between primary data points and
+entries in these RRAs. For the \s-1HWPREDICT\s0 \s-1CF\s0, \fIrows\fR should be larger than
+the \fIseasonal period\fR. If the \s-1DEVPREDICT\s0 \fB\s-1RRA\s0\fR is implicitly created, the
+default number of rows is the same as the \s-1HWPREDICT\s0 \fIrows\fR argument. If the
+\&\s-1FAILURES\s0 \fB\s-1RRA\s0\fR is implicitly created, \fIrows\fR will be set to the \fIseasonal
+period\fR argument of the \s-1HWPREDICT\s0 \fB\s-1RRA\s0\fR. Of course, the \fBRRDtool\fR
+\&\fIresize\fR command is available if these defaults are not sufficient and the
+creator wishes to avoid explicit creations of the other specialized function
+\&\fBRRAs\fR.
+.PP
+\&\fIseasonal period\fR specifies the number of primary data points in a seasonal
+cycle. If \s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 are implicitly created, this argument for
+those \fBRRAs\fR is set automatically to the value specified by \s-1HWPREDICT\s0. If
+they are explicitly created, the creator should verify that all three
+\&\fIseasonal period\fR arguments agree.
+.PP
+\&\fIalpha\fR is the adaption parameter of the intercept (or baseline)
+coefficient in the Holt-Winters forecasting algorithm. See rrdtool for a
+description of this algorithm. \fIalpha\fR must lie between 0 and 1. A value
+closer to 1 means that more recent observations carry greater weight in
+predicting the baseline component of the forecast. A value closer to 0 means
+that past history carries greater weight in predicting the baseline
+component.
+.PP
+\&\fIbeta\fR is the adaption parameter of the slope (or linear trend) coefficient
+in the Holt-Winters forecasting algorithm. \fIbeta\fR must lie between 0 and 1
+and plays the same role as \fIalpha\fR with respect to the predicted linear
+trend.
+.PP
+\&\fIgamma\fR is the adaption parameter of the seasonal coefficients in the
+Holt-Winters forecasting algorithm (\s-1HWPREDICT\s0) or the adaption parameter in
+the exponential smoothing update of the seasonal deviations. It must lie
+between 0 and 1. If the \s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 \fBRRAs\fR are created
+implicitly, they will both have the same value for \fIgamma\fR: the value
+specified for the \s-1HWPREDICT\s0 \fIalpha\fR argument. Note that because there is
+one seasonal coefficient (or deviation) for each time point during the
+seasonal cycle, the adaptation rate is much slower than the baseline. Each
+seasonal coefficient is only updated (or adapts) when the observed value
+occurs at the offset in the seasonal cycle corresponding to that
+coefficient.
+.PP
+If \s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 \fBRRAs\fR are created explicitly, \fIgamma\fR need not
+be the same for both. Note that \fIgamma\fR can also be changed via the
+\&\fBRRDtool\fR \fItune\fR command.
+.PP
+\&\fIrra-num\fR provides the links between related \fBRRAs\fR. If \s-1HWPREDICT\s0 is
+specified alone and the other \fBRRAs\fR are created implicitly, then
+there is no need to worry about this argument. If \fBRRAs\fR are created
+explicitly, then carefully pay attention to this argument. For each
+\&\fB\s-1RRA\s0\fR which includes this argument, there is a dependency between
+that \fB\s-1RRA\s0\fR and another \fB\s-1RRA\s0\fR. The \fIrra-num\fR argument is the 1\-based
+index in the order of \fB\s-1RRA\s0\fR creation (that is, the order they appear
+in the \fIcreate\fR command). The dependent \fB\s-1RRA\s0\fR for each \fB\s-1RRA\s0\fR

+.SH "The HEARTBEAT and the STEP"
+.IX Header "The HEARTBEAT and the STEP"
+Here is an explanation by Don Baarda on the inner workings of RRDtool.
+It may help you to sort out why all this *UNKNOWN* data is popping
+up in your databases:
+.PP
+RRDtool gets fed samples at arbitrary times. From these it builds Primary
+Data Points (PDPs) at exact times on every \*(L"step\*(R" interval. The PDPs are
+then accumulated into RRAs.
+.PP
+The \*(L"heartbeat\*(R" defines the maximum acceptable interval between
+samples. If the interval between samples is less than \*(L"heartbeat\*(R",
+then an average rate is calculated and applied for that interval. If
+the interval between samples is longer than \*(L"heartbeat\*(R", then that
+entire interval is considered \*(L"unknown\*(R". Note that there are other
+things that can make a sample interval \*(L"unknown\*(R", such as the rate
+exceeding limits, or even an \*(L"unknown\*(R" input sample.
+.PP
+The known rates during a \s-1PDP\s0's \*(L"step\*(R" interval are used to calculate
+an average rate for that \s-1PDP\s0. Also, if the total \*(L"unknown\*(R" time during
+the \*(L"step\*(R" interval exceeds the \*(L"heartbeat\*(R", the entire \s-1PDP\s0 is marked
+as \*(L"unknown\*(R". This means that a mixture of known and \*(L"unknown\*(R" sample
+times in a single \s-1PDP\s0 \*(L"step\*(R" may or may not add up to enough \*(L"unknown\*(R"
+time to exceed \*(L"heartbeat\*(R" and hence mark the whole \s-1PDP\s0 \*(L"unknown\*(R". So
+\&\*(L"heartbeat\*(R" is not only the maximum acceptable interval between
+samples, but also the maximum acceptable amount of \*(L"unknown\*(R" time per
+\&\s-1PDP\s0 (obviously this is only significant if you have \*(L"heartbeat\*(R" less
+than \*(L"step\*(R").
+.PP
+The \*(L"heartbeat\*(R" can be short (unusual) or long (typical) relative to
+the \*(L"step\*(R" interval between PDPs. A short \*(L"heartbeat\*(R" means you
+require multiple samples per \s-1PDP\s0, and if you don't get them mark the
+\&\s-1PDP\s0 unknown. A long heartbeat can span multiple \*(L"steps\*(R", which means
+it is acceptable to have multiple PDPs calculated from a single
+sample. An extreme example of this might be a \*(L"step\*(R" of 5 minutes and a
+\&\*(L"heartbeat\*(R" of one day, in which case a single sample every day will
+result in all the PDPs for that entire day period being set to the
+same average rate. \fI\-\- Don Baarda <don.baarda@baesystems.com>\fR

+.SH "HOW TO MEASURE"
+.IX Header "HOW TO MEASURE"
+Here are a few hints on how to measure:
+.IP "Temperature" 4
+.IX Item "Temperature"
+Usually you have some type of meter you can read to get the temperature.
+The temperature is not really connected with a time. The only connection is
+that the temperature reading happened at a certain time. You can use the
+\&\fB\s-1GAUGE\s0\fR data source type for this. RRDtool will then record your reading
+together with the time.
+.IP "Mail Messages" 4
+.IX Item "Mail Messages"
+Assume you have a method to count the number of messages transported by
+your mailserver in a certain amount of time, giving you data like '5
+messages in the last 65 seconds'. If you look at the count of 5 like an
+\&\fB\s-1ABSOLUTE\s0\fR data type you can simply update the \s-1RRD\s0 with the number 5 and the
+end time of your monitoring period. RRDtool will then record the number of
+messages per second. If at some later stage you want to know the number of
+messages transported in a day, you can get the average messages per second
+from RRDtool for the day in question and multiply this number with the
+number of seconds in a day. Because all math is run with Doubles, the
+precision should be acceptable.
+.IP "It's always a Rate" 4
+.IX Item "It's always a Rate"
+RRDtool stores rates in amount/second for \s-1COUNTER\s0, \s-1DERIVE\s0 and \s-1ABSOLUTE\s0
+data.  When you plot the data, you will get on the y axis
+amount/second which you might be tempted to convert to an absolute
+amount by multiplying by the delta-time between the points. RRDtool
+plots continuous data, and as such is not appropriate for plotting
+absolute amounts as for example \*(L"total bytes\*(R" sent and received in a
+router. What you probably want is plot rates that you can scale to
+bytes/hour, for example, or plot absolute amounts with another tool
+that draws bar\-plots, where the delta-time is clear on the plot for
+each point (such that when you read the graph you see for example \s-1GB\s0
+on the y axis, days on the x axis and one bar for each day).

+argument of \s-1HWPREDICT\s0 is missing, so the other \fBRRAs\fR will implicitly be
+created with default parameter values. In this example, the forecasting
+algorithm baseline adapts quickly; in fact the most recent one hour of
+observations (each at 5 minute intervals) accounts for 75% of the baseline
+prediction. The linear trend forecast adapts much more slowly. Observations
+made during the last day (at 288 observations per day) account for only
+65% of the predicted linear trend. Note: these computations rely on an

+In this case, the proxy exposes two counters, the number of requests
+processed since boot and the total cumulative duration of all processed

+stopped and restarted.

+requests processed during the interval divided by 300. The \s-1COMPUTE\s0 data source
+divides each \s-1PDP\s0 of the AccumDuration by the corresponding \s-1PDP\s0 of
+TotalRequests and stores the average request duration. The remainder of the

+the overflow into account.  The counter is stored as a per-second

+example, to measure the rate of people entering or leaving a
+room. Internally, derive works exactly like COUNTER but without
+overflow checks. So if your counter does not reset at 32 or 64 bit you
+might want to use DERIVE and combine it with a MIN value of 0.</p>

+</dd>
+<dd>
+<p>If you cannot tolerate ever mistaking the occasional counter reset for a
+legitimate counter wrap, and would prefer ``Unknowns'' for all legitimate
+counter wraps and resets, always use DERIVE with min=0. Otherwise, using
+COUNTER with a suitable max will return correct values for all legitimate
+counter wraps, mark some counter resets as ``Unknown'', but can mistake some
+counter resets for a legitimate counter wrap.</p>
+</dd>
+<dd>
+<p>For a 5 minute step and 32-bit counter, the probability of mistaking a
+counter reset for a legitimate wrap is arguably about 0.8% per 1Mbps of
+maximum bandwidth. Note that this equates to 80% for 100Mbps interfaces, so
+for high bandwidth interfaces and a 32bit counter, DERIVE with min=0 is
+probably preferable. If you are using a 64bit counter, just about any max
+setting will eliminate the possibility of mistaking a reset for a counter
+wrap.</p>

+
+<dd>
+<p>is for counters which get reset upon reading. This is used for fast counters
+which tend to overflow. So instead of reading them normally you reset them
+after every read to make sure you have a maximum time available before the
+next overflow. Another usage is for things you count like number of messages
+since the last update.</p>

+<p>is for storing the result of a formula applied to other data sources
+in the <strong>RRD</strong>. This data source is not supplied a value on update, but
+rather its Primary Data Points (PDPs) are computed from the PDPs of
+the data sources according to the rpn-expression that defines the
+formula. Consolidation functions are then applied normally to the PDPs
+of the COMPUTE data source (that is the rpn-expression is only applied
+to generate PDPs). In database software, such data sets are referred
+to as ``virtual'' or ``computed'' columns.</p>

+<p><em>heartbeat</em> defines the maximum number of seconds that may pass
+between two updates of this data source before the value of the
+data source is assumed to be <em>*UNKNOWN*</em>.</p>
+<p><em>min</em> and <em>max</em> define the expected range values for data supplied by a
+data source. If <em>min</em> and/or <em>max</em> any value outside the defined range
+will be regarded as <em>*UNKNOWN*</em>. If you do not know or care about min and
+max, set them to U for unknown. Note that min and max always refer to the
+processed values of the DS. For a traffic-<strong>COUNTER</strong> type DS this would be
+the maximum and minimum data-rate expected from the device.</p>
+<p><em>If information on minimal/maximal expected values is available,
+always set the min and/or max properties. This will help RRDtool in
+doing a simple sanity check on the data supplied when running update.</em></p>
+<p><em>rpn-expression</em> defines the formula used to compute the PDPs of a
+COMPUTE data source from other data sources in the same &lt;RRD&gt;. It is
+similar to defining a <strong>CDEF</strong> argument for the graph command. Please
+refer to that manual page for a list and description of RPN operations
+supported. For COMPUTE data sources, the following RPN operations are
+not supported: COUNT, PREV, TIME, and LTIME. In addition, in defining
+the RPN expression, the COMPUTE data source may only refer to the
+names of data source listed previously in the create command. This is
+similar to the restriction that <strong>CDEF</strong>s must refer only to <strong>DEF</strong>s
+and <strong>CDEF</strong>s previously defined in the same graph command.</p>

+<p>The purpose of an <strong>RRD</strong> is to store data in the round robin archives
+(<strong>RRA</strong>). An archive consists of a number of data values or statistics for

+<dd>
+<p>The data is also processed with the consolidation function (<em>CF</em>) of
+the archive. There are several consolidation functions that
+consolidate primary data points via an aggregate function: <strong>AVERAGE</strong>,
+<strong>MIN</strong>, <strong>MAX</strong>, <strong>LAST</strong>. The format of <strong>RRA</strong> line for these

+<h1><a name="aberrant_behavior_detection_with_holtwinters_forecasting">Aberrant Behavior Detection with Holt-Winters Forecasting</a></h1>
+<p>In addition to the aggregate functions, there are a set of specialized
+functions that enable <strong>RRDtool</strong> to provide data smoothing (via the
+Holt-Winters forecasting algorithm), confidence bands, and the
+flagging aberrant behavior in the data source time series:</p>
+<ul>
+<li>
+<p><strong>RRA:</strong><em>HWPREDICT</em><strong>:</strong><em>rows</em><strong>:</strong><em>alpha</em><strong>:</strong><em>beta</em><strong>:</strong><em>seasonal period</em>[<strong>:</strong><em>rra-num</em>]</p>
+</li>
+<li>
+<p><strong>RRA:</strong><em>SEASONAL</em><strong>:</strong><em>seasonal period</em><strong>:</strong><em>gamma</em><strong>:</strong><em>rra-num</em></p>
+</li>
+<li>
+<p><strong>RRA:</strong><em>DEVSEASONAL</em><strong>:</strong><em>seasonal period</em><strong>:</strong><em>gamma</em><strong>:</strong><em>rra-num</em></p>
+</li>
+<li>
+<p><strong>RRA:</strong><em>DEVPREDICT</em><strong>:</strong><em>rows</em><strong>:</strong><em>rra-num</em></p>
+</li>
+<li>
+<p><strong>RRA:</strong><em>FAILURES</em><strong>:</strong><em>rows</em><strong>:</strong><em>threshold</em><strong>:</strong><em>window length</em><strong>:</strong><em>rra-num</em></p>
+</li>
+</ul>
+<p>These <strong>RRAs</strong> differ from the true consolidation functions in several ways.
+First, each of the <strong>RRA</strong>s is updated once for every primary data point.
+Second, these <strong>RRAs</strong> are interdependent. To generate real-time confidence
+bounds, a matched set of HWPREDICT, SEASONAL, DEVSEASONAL, and
+DEVPREDICT must exist. Generating smoothed values of the primary data points
+requires both a HWPREDICT <strong>RRA</strong> and SEASONAL <strong>RRA</strong>. Aberrant behavior
+detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEASONAL.</p>
+<p>The actual predicted, or smoothed, values are stored in the HWPREDICT
+<strong>RRA</strong>. The predicted deviations are stored in DEVPREDICT (think a standard
+deviation which can be scaled to yield a confidence band). The FAILURES
+<strong>RRA</strong> stores binary indicators. A 1 marks the indexed observation as
+failure; that is, the number of confidence bounds violations in the
+preceding window of observations met or exceeded a specified threshold. An
+example of using these <strong>RRAs</strong> to graph confidence bounds and failures
+appears in <a href="././rrdgraph.html">the rrdgraph manpage</a>.</p>
+<p>The SEASONAL and DEVSEASONAL <strong>RRAs</strong> store the seasonal coefficients for the
+Holt-Winters forecasting algorithm and the seasonal deviations, respectively.
+There is one entry per observation time point in the seasonal cycle. For
+example, if primary data points are generated every five minutes and the
+seasonal cycle is 1 day, both SEASONAL and DEVSEASONAL will have 288 rows.</p>
+<p>In order to simplify the creation for the novice user, in addition to
+supporting explicit creation of the HWPREDICT, SEASONAL, DEVPREDICT,
+DEVSEASONAL, and FAILURES <strong>RRAs</strong>, the <strong>RRDtool</strong> create command supports
+implicit creation of the other four when HWPREDICT is specified alone and
+the final argument <em>rra-num</em> is omitted.</p>
+<p><em>rows</em> specifies the length of the <strong>RRA</strong> prior to wrap around. Remember
+that there is a one-to-one correspondence between primary data points and
+entries in these RRAs. For the HWPREDICT CF, <em>rows</em> should be larger than
+the <em>seasonal period</em>. If the DEVPREDICT <strong>RRA</strong> is implicitly created, the
+default number of rows is the same as the HWPREDICT <em>rows</em> argument. If the
+FAILURES <strong>RRA</strong> is implicitly created, <em>rows</em> will be set to the <em>seasonal
+period</em> argument of the HWPREDICT <strong>RRA</strong>. Of course, the <strong>RRDtool</strong>
+<em>resize</em> command is available if these defaults are not sufficient and the
+creator wishes to avoid explicit creations of the other specialized function
+<strong>RRAs</strong>.</p>
+<p><em>seasonal period</em> specifies the number of primary data points in a seasonal
+cycle. If SEASONAL and DEVSEASONAL are implicitly created, this argument for
+those <strong>RRAs</strong> is set automatically to the value specified by HWPREDICT. If
+they are explicitly created, the creator should verify that all three
+<em>seasonal period</em> arguments agree.</p>
+<p><em>alpha</em> is the adaption parameter of the intercept (or baseline)
+coefficient in the Holt-Winters forecasting algorithm. See <a href="././rrdtool.html">the rrdtool manpage</a> for a
+description of this algorithm. <em>alpha</em> must lie between 0 and 1. A value
+closer to 1 means that more recent observations carry greater weight in
+predicting the baseline component of the forecast. A value closer to 0 means
+that past history carries greater weight in predicting the baseline
+component.</p>
+<p><em>beta</em> is the adaption parameter of the slope (or linear trend) coefficient
+in the Holt-Winters forecasting algorithm. <em>beta</em> must lie between 0 and 1
+and plays the same role as <em>alpha</em> with respect to the predicted linear
+trend.</p>
+<p><em>gamma</em> is the adaption parameter of the seasonal coefficients in the
+Holt-Winters forecasting algorithm (HWPREDICT) or the adaption parameter in
+the exponential smoothing update of the seasonal deviations. It must lie
+between 0 and 1. If the SEASONAL and DEVSEASONAL <strong>RRAs</strong> are created
+implicitly, they will both have the same value for <em>gamma</em>: the value
+specified for the HWPREDICT <em>alpha</em> argument. Note that because there is
+one seasonal coefficient (or deviation) for each time point during the
+seasonal cycle, the adaptation rate is much slower than the baseline. Each
+seasonal coefficient is only updated (or adapts) when the observed value
+occurs at the offset in the seasonal cycle corresponding to that
+coefficient.</p>
+<p>If SEASONAL and DEVSEASONAL <strong>RRAs</strong> are created explicitly, <em>gamma</em> need not
+be the same for both. Note that <em>gamma</em> can also be changed via the
+<strong>RRDtool</strong> <em>tune</em> command.</p>
+<p><em>rra-num</em> provides the links between related <strong>RRAs</strong>. If HWPREDICT is
+specified alone and the other <strong>RRAs</strong> are created implicitly, then
+there is no need to worry about this argument. If <strong>RRAs</strong> are created
+explicitly, then carefully pay attention to this argument. For each
+<strong>RRA</strong> which includes this argument, there is a dependency between
+that <strong>RRA</strong> and another <strong>RRA</strong>. The <em>rra-num</em> argument is the 1-based
+index in the order of <strong>RRA</strong> creation (that is, the order they appear
+in the <em>create</em> command). The dependent <strong>RRA</strong> for each <strong>RRA</strong>
+requiring the <em>rra-num</em> argument is listed here:</p>
+<ul>
+<li>
+<p>HWPREDICT <em>rra-num</em> is the index of the SEASONAL <strong>RRA</strong>.</p>
+</li>
+<li>
+<p>SEASONAL <em>rra-num</em> is the index of the HWPREDICT <strong>RRA</strong>.</p>
+</li>
+<li>
+<p>DEVPREDICT <em>rra-num</em> is the index of the DEVSEASONAL <strong>RRA</strong>.</p>
+</li>

+<p>DEVSEASONAL <em>rra-num</em> is the index of the HWPREDICT <strong>RRA</strong>.</p>
+</li>
+<li>
+<p>FAILURES <em>rra-num</em> is the index of the DEVSEASONAL <strong>RRA</strong>.</p>
+</li>
+</ul>
+<p><em>threshold</em> is the minimum number of violations (observed values outside
+the confidence bounds) within a window that constitutes a failure. If the
+FAILURES <strong>RRA</strong> is implicitly created, the default value is 7.</p>
+<p><em>window length</em> is the number of time points in the window. Specify an
+integer greater than or equal to the threshold and less than or equal to 28.
+The time interval this window represents depends on the interval between
+primary data points. If the FAILURES <strong>RRA</strong> is implicitly created, the
+default value is 9.</p>

+<h1><a name="the_heartbeat_and_the_step">The HEARTBEAT and the STEP</a></h1>
+<p>Here is an explanation by Don Baarda on the inner workings of RRDtool.
+It may help you to sort out why all this *UNKNOWN* data is popping
+up in your databases:</p>
+<p>RRDtool gets fed samples at arbitrary times. From these it builds Primary
+Data Points (PDPs) at exact times on every ``step'' interval. The PDPs are
+then accumulated into RRAs.</p>
+<p>The ``heartbeat'' defines the maximum acceptable interval between
+samples. If the interval between samples is less than ``heartbeat'',
+then an average rate is calculated and applied for that interval. If
+the interval between samples is longer than ``heartbeat'', then that
+entire interval is considered ``unknown''. Note that there are other
+things that can make a sample interval ``unknown'', such as the rate
+exceeding limits, or even an ``unknown'' input sample.</p>
+<p>The known rates during a PDP's ``step'' interval are used to calculate
+an average rate for that PDP. Also, if the total ``unknown'' time during
+the ``step'' interval exceeds the ``heartbeat'', the entire PDP is marked
+as ``unknown''. This means that a mixture of known and ``unknown'' sample
+times in a single PDP ``step'' may or may not add up to enough ``unknown''
+time to exceed ``heartbeat'' and hence mark the whole PDP ``unknown''. So
+``heartbeat'' is not only the maximum acceptable interval between
+samples, but also the maximum acceptable amount of ``unknown'' time per
+PDP (obviously this is only significant if you have ``heartbeat'' less
+than ``step'').</p>
+<p>The ``heartbeat'' can be short (unusual) or long (typical) relative to
+the ``step'' interval between PDPs. A short ``heartbeat'' means you
+require multiple samples per PDP, and if you don't get them mark the
+PDP unknown. A long heartbeat can span multiple ``steps'', which means
+it is acceptable to have multiple PDPs calculated from a single
+sample. An extreme example of this might be a ``step'' of 5 minutes and a
+``heartbeat'' of one day, in which case a single sample every day will
+result in all the PDPs for that entire day period being set to the
+same average rate. <em>-- Don Baarda &lt;<a href="mailto:don.baarda@baesystems.com">don.baarda@baesystems.com</a>&gt;</em></p>

+<h1><a name="how_to_measure">HOW TO MEASURE</a></h1>
+<p>Here are a few hints on how to measure:</p>
+<dl>
+<dt><strong><a name="item_temperature">Temperature</a></strong>
+
+<dd>
+<p>Usually you have some type of meter you can read to get the temperature.
+The temperature is not really connected with a time. The only connection is
+that the temperature reading happened at a certain time. You can use the
+<strong>GAUGE</strong> data source type for this. RRDtool will then record your reading
+together with the time.</p>
+</dd>
+</li>
+<dt><strong><a name="item_mail_messages">Mail Messages</a></strong>
+
+<dd>
+<p>Assume you have a method to count the number of messages transported by
+your mailserver in a certain amount of time, giving you data like '5
+messages in the last 65 seconds'. If you look at the count of 5 like an
+<strong>ABSOLUTE</strong> data type you can simply update the RRD with the number 5 and the
+end time of your monitoring period. RRDtool will then record the number of
+messages per second. If at some later stage you want to know the number of
+messages transported in a day, you can get the average messages per second
+from RRDtool for the day in question and multiply this number with the
+number of seconds in a day. Because all math is run with Doubles, the
+precision should be acceptable.</p>
+</dd>
+</li>
+<dt><strong><a name="item_it_27s_always_a_rate">It's always a Rate</a></strong>
+
+<dd>
+<p>RRDtool stores rates in amount/second for COUNTER, DERIVE and ABSOLUTE
+data.  When you plot the data, you will get on the y axis
+amount/second which you might be tempted to convert to an absolute
+amount by multiplying by the delta-time between the points. RRDtool
+plots continuous data, and as such is not appropriate for plotting
+absolute amounts as for example ``total bytes'' sent and received in a
+router. What you probably want is plot rates that you can scale to
+bytes/hour, for example, or plot absolute amounts with another tool
+that draws bar-plots, where the delta-time is clear on the plot for
+each point (such that when you read the graph you see for example GB
+on the y axis, days on the x axis and one bar for each day).</p>

+more than 600 seconds, the temperature becomes <em>*UNKNOWN*</em>.  The

+<p>A few archive areas are also defined. The first stores the
+temperatures supplied for 100 hours (1'200 * 300 seconds = 100
+hours). The second RRA stores the minimum temperature recorded over
+every hour (12 * 300 seconds = 1 hour), for 100 days (2'400 hours). The

+observations (each at 5 minute intervals) accounts for 75% of the baseline
+prediction. The linear trend forecast adapts much more slowly. Observations

+rrdcreate - Set up a new Round Robin Database
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<create> I<filename>
+S<[B<--start>|B<-b> I<start time>]>
+S<[B<--step>|B<-s> I<step>]>
+S<[B<DS:>I<ds-name>B<:>I<DST>B<:>I<dst arguments>]>
+S<[B<RRA:>I<CF>B<:>I<cf arguments>]>
+
+=head1 DESCRIPTION
+
+The create function of RRDtool lets you set up new Round Robin
+Database (B<RRD>) files.  The file is created at its final, full size
+and filled with I<*UNKNOWN*> data.
+
+=over 8
+
+=item I<filename>
+
+The name of the B<RRD> you want to create. B<RRD> files should end
+with the extension F<.rrd>. However, B<RRDtool> will accept any
+filename.
+
+=item B<--start>|B<-b> I<start time> (default: now - 10s)
+
+Specifies the time in seconds since 1970-01-01 UTC when the first
+value should be added to the B<RRD>. B<RRDtool> will not accept
+any data timed before or at the time specified.
+
+See also AT-STYLE TIME SPECIFICATION section in the
+I<rrdfetch> documentation for other ways to specify time.
+
+=item B<--step>|B<-s> I<step> (default: 300 seconds)
+
+Specifies the base interval in seconds with which data will be fed
+into the B<RRD>.
+
+=item B<DS:>I<ds-name>B<:>I<DST>B<:>I<dst arguments>
+
+A single B<RRD> can accept input from several data sources (B<DS>),
+for example incoming and outgoing traffic on a specific communication
+line. With the B<DS> configuration option you must define some basic
+properties of each data source you want to store in the B<RRD>.
+
+I<ds-name> is the name you will use to reference this particular data
+source from an B<RRD>. A I<ds-name> must be 1 to 19 characters long in
+the characters [a-zA-Z0-9_].
+
+I<DST> defines the Data Source Type. The remaining arguments of a
+data source entry depend on the data source type. For GAUGE, COUNTER,
+DERIVE, and ABSOLUTE the format for a data source entry is:
+
+B<DS:>I<ds-name>B<:>I<GAUGE | COUNTER | DERIVE | ABSOLUTE>B<:>I<heartbeat>B<:>I<min>B<:>I<max>
+
+For COMPUTE data sources, the format is:
+
+B<DS:>I<ds-name>B<:>I<COMPUTE>B<:>I<rpn-expression>
+
+In order to decide which data source type to use, review the
+definitions that follow. Also consult the section on "HOW TO MEASURE"
+for further insight.
+
+=over 4
+
+=item B<GAUGE>
+
+is for things like temperatures or number of people in a room or the
+value of a RedHat share.
+
+=item B<COUNTER>
+
+is for continuous incrementing counters like the ifInOctets counter in
+a router. The B<COUNTER> data source assumes that the counter never
+decreases, except when a counter overflows.  The update function takes
+the overflow into account.  The counter is stored as a per-second
+rate. When the counter overflows, RRDtool checks if the overflow
+happened at the 32bit or 64bit border and acts accordingly by adding
+an appropriate value to the result.
+
+=item B<DERIVE>
+
+will store the derivative of the line going from the last to the
+current value of the data source. This can be useful for gauges, for
+example, to measure the rate of people entering or leaving a
+room. Internally, derive works exactly like COUNTER but without
+overflow checks. So if your counter does not reset at 32 or 64 bit you
+might want to use DERIVE and combine it with a MIN value of 0.
+

+
+=item NOTE on COUNTER vs DERIVE
+
+by Don Baarda E<lt>don.baarda@baesystems.comE<gt>
+
+If you cannot tolerate ever mistaking the occasional counter reset for a
+legitimate counter wrap, and would prefer "Unknowns" for all legitimate
+counter wraps and resets, always use DERIVE with min=0. Otherwise, using
+COUNTER with a suitable max will return correct values for all legitimate
+counter wraps, mark some counter resets as "Unknown", but can mistake some
+counter resets for a legitimate counter wrap.
+
+For a 5 minute step and 32-bit counter, the probability of mistaking a
+counter reset for a legitimate wrap is arguably about 0.8% per 1Mbps of
+maximum bandwidth. Note that this equates to 80% for 100Mbps interfaces, so
+for high bandwidth interfaces and a 32bit counter, DERIVE with min=0 is
+probably preferable. If you are using a 64bit counter, just about any max
+setting will eliminate the possibility of mistaking a reset for a counter
+wrap.
+
+=back
+
+=item B<ABSOLUTE>
+
+is for counters which get reset upon reading. This is used for fast counters
+which tend to overflow. So instead of reading them normally you reset them
+after every read to make sure you have a maximum time available before the
+next overflow. Another usage is for things you count like number of messages
+since the last update.
+
+=item B<COMPUTE>
+
+is for storing the result of a formula applied to other data sources
+in the B<RRD>. This data source is not supplied a value on update, but
+rather its Primary Data Points (PDPs) are computed from the PDPs of
+the data sources according to the rpn-expression that defines the
+formula. Consolidation functions are then applied normally to the PDPs
+of the COMPUTE data source (that is the rpn-expression is only applied
+to generate PDPs). In database software, such data sets are referred
+to as "virtual" or "computed" columns.
+
+=back
+
+I<heartbeat> defines the maximum number of seconds that may pass
+between two updates of this data source before the value of the
+data source is assumed to be I<*UNKNOWN*>.
+
+I<min> and I<max> define the expected range values for data supplied by a
+data source. If I<min> and/or I<max> any value outside the defined range
+will be regarded as I<*UNKNOWN*>. If you do not know or care about min and
+max, set them to U for unknown. Note that min and max always refer to the
+processed values of the DS. For a traffic-B<COUNTER> type DS this would be
+the maximum and minimum data-rate expected from the device.
+
+I<If information on minimal/maximal expected values is available,
+always set the min and/or max properties. This will help RRDtool in
+doing a simple sanity check on the data supplied when running update.>
+
+I<rpn-expression> defines the formula used to compute the PDPs of a
+COMPUTE data source from other data sources in the same <RRD>. It is
+similar to defining a B<CDEF> argument for the graph command. Please
+refer to that manual page for a list and description of RPN operations
+supported. For COMPUTE data sources, the following RPN operations are
+not supported: COUNT, PREV, TIME, and LTIME. In addition, in defining
+the RPN expression, the COMPUTE data source may only refer to the
+names of data source listed previously in the create command. This is
+similar to the restriction that B<CDEF>s must refer only to B<DEF>s
+and B<CDEF>s previously defined in the same graph command.
+
+=item B<RRA:>I<CF>B<:>I<cf arguments>
+
+
+The purpose of an B<RRD> is to store data in the round robin archives
+(B<RRA>). An archive consists of a number of data values or statistics for
+each of the defined data-sources (B<DS>) and is defined with an B<RRA> line.
+
+When data is entered into an B<RRD>, it is first fit into time slots
+of the length defined with the B<-s> option, thus becoming a I<primary
+data point>.
+
+The data is also processed with the consolidation function (I<CF>) of
+the archive. There are several consolidation functions that
+consolidate primary data points via an aggregate function: B<AVERAGE>,
+B<MIN>, B<MAX>, B<LAST>. The format of B<RRA> line for these
+consolidation functions is:
+
+B<RRA:>I<AVERAGE | MIN | MAX | LAST>B<:>I<xff>B<:>I<steps>B<:>I<rows>
+
+I<xff> The xfiles factor defines what part of a consolidation interval may
+be made up from I<*UNKNOWN*> data while the consolidated value is still
+regarded as known. It is given as the ratio of allowed I<*UNKNOWN*> PDPs
+to the number of PDPs in the interval. Thus, it ranges from 0 to 1 (exclusive).
+
+
+I<steps> defines how many of these I<primary data points> are used to build
+a I<consolidated data point> which then goes into the archive.
+
+I<rows> defines how many generations of data values are kept in an B<RRA>.
+
+=back
+
+=head1 Aberrant Behavior Detection with Holt-Winters Forecasting
+
+In addition to the aggregate functions, there are a set of specialized
+functions that enable B<RRDtool> to provide data smoothing (via the
+Holt-Winters forecasting algorithm), confidence bands, and the
+flagging aberrant behavior in the data source time series:
+
+=over
+
+=item *
+
+B<RRA:>I<HWPREDICT>B<:>I<rows>B<:>I<alpha>B<:>I<beta>B<:>I<seasonal period>[B<:>I<rra-num>]
+
+=item *
+
+B<RRA:>I<SEASONAL>B<:>I<seasonal period>B<:>I<gamma>B<:>I<rra-num>
+
+=item *
+
+B<RRA:>I<DEVSEASONAL>B<:>I<seasonal period>B<:>I<gamma>B<:>I<rra-num>
+
+=item *
+
+B<RRA:>I<DEVPREDICT>B<:>I<rows>B<:>I<rra-num>
+
+=item *
+
+B<RRA:>I<FAILURES>B<:>I<rows>B<:>I<threshold>B<:>I<window length>B<:>I<rra-num>
+
+=back
+
+These B<RRAs> differ from the true consolidation functions in several ways.
+First, each of the B<RRA>s is updated once for every primary data point.
+Second, these B<RRAs> are interdependent. To generate real-time confidence
+bounds, a matched set of HWPREDICT, SEASONAL, DEVSEASONAL, and
+DEVPREDICT must exist. Generating smoothed values of the primary data points
+requires both a HWPREDICT B<RRA> and SEASONAL B<RRA>. Aberrant behavior
+detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEASONAL.
+
+The actual predicted, or smoothed, values are stored in the HWPREDICT
+B<RRA>. The predicted deviations are stored in DEVPREDICT (think a standard
+deviation which can be scaled to yield a confidence band). The FAILURES
+B<RRA> stores binary indicators. A 1 marks the indexed observation as
+failure; that is, the number of confidence bounds violations in the
+preceding window of observations met or exceeded a specified threshold. An
+example of using these B<RRAs> to graph confidence bounds and failures
+appears in L<rrdgraph>.
+
+The SEASONAL and DEVSEASONAL B<RRAs> store the seasonal coefficients for the
+Holt-Winters forecasting algorithm and the seasonal deviations, respectively.
+There is one entry per observation time point in the seasonal cycle. For
+example, if primary data points are generated every five minutes and the
+seasonal cycle is 1 day, both SEASONAL and DEVSEASONAL will have 288 rows.
+
+In order to simplify the creation for the novice user, in addition to
+supporting explicit creation of the HWPREDICT, SEASONAL, DEVPREDICT,
+DEVSEASONAL, and FAILURES B<RRAs>, the B<RRDtool> create command supports
+implicit creation of the other four when HWPREDICT is specified alone and
+the final argument I<rra-num> is omitted.
+
+I<rows> specifies the length of the B<RRA> prior to wrap around. Remember
+that there is a one-to-one correspondence between primary data points and
+entries in these RRAs. For the HWPREDICT CF, I<rows> should be larger than
+the I<seasonal period>. If the DEVPREDICT B<RRA> is implicitly created, the
+default number of rows is the same as the HWPREDICT I<rows> argument. If the
+FAILURES B<RRA> is implicitly created, I<rows> will be set to the I<seasonal
+period> argument of the HWPREDICT B<RRA>. Of course, the B<RRDtool>
+I<resize> command is available if these defaults are not sufficient and the
+creator wishes to avoid explicit creations of the other specialized function
+B<RRAs>.
+
+I<seasonal period> specifies the number of primary data points in a seasonal
+cycle. If SEASONAL and DEVSEASONAL are implicitly created, this argument for
+those B<RRAs> is set automatically to the value specified by HWPREDICT. If
+they are explicitly created, the creator should verify that all three
+I<seasonal period> arguments agree.
+
+I<alpha> is the adaption parameter of the intercept (or baseline)
+coefficient in the Holt-Winters forecasting algorithm. See L<rrdtool> for a
+description of this algorithm. I<alpha> must lie between 0 and 1. A value
+closer to 1 means that more recent observations carry greater weight in
+predicting the baseline component of the forecast. A value closer to 0 means
+that past history carries greater weight in predicting the baseline
+component.
+
+I<beta> is the adaption parameter of the slope (or linear trend) coefficient
+in the Holt-Winters forecasting algorithm. I<beta> must lie between 0 and 1
+and plays the same role as I<alpha> with respect to the predicted linear
+trend.
+
+I<gamma> is the adaption parameter of the seasonal coefficients in the
+Holt-Winters forecasting algorithm (HWPREDICT) or the adaption parameter in
+the exponential smoothing update of the seasonal deviations. It must lie
+between 0 and 1. If the SEASONAL and DEVSEASONAL B<RRAs> are created
+implicitly, they will both have the same value for I<gamma>: the value
+specified for the HWPREDICT I<alpha> argument. Note that because there is
+one seasonal coefficient (or deviation) for each time point during the
+seasonal cycle, the adaptation rate is much slower than the baseline. Each
+seasonal coefficient is only updated (or adapts) when the observed value
+occurs at the offset in the seasonal cycle corresponding to that
+coefficient.
+
+If SEASONAL and DEVSEASONAL B<RRAs> are created explicitly, I<gamma> need not
+be the same for both. Note that I<gamma> can also be changed via the
+B<RRDtool> I<tune> command.
+
+I<rra-num> provides the links between related B<RRAs>. If HWPREDICT is
+specified alone and the other B<RRAs> are created implicitly, then
+there is no need to worry about this argument. If B<RRAs> are created
+explicitly, then carefully pay attention to this argument. For each
+B<RRA> which includes this argument, there is a dependency between
+that B<RRA> and another B<RRA>. The I<rra-num> argument is the 1-based
+index in the order of B<RRA> creation (that is, the order they appear
+in the I<create> command). The dependent B<RRA> for each B<RRA>
+requiring the I<rra-num> argument is listed here:

+
+=head1 The HEARTBEAT and the STEP
+
+Here is an explanation by Don Baarda on the inner workings of RRDtool.
+It may help you to sort out why all this *UNKNOWN* data is popping
+up in your databases:
+
+RRDtool gets fed samples at arbitrary times. From these it builds Primary
+Data Points (PDPs) at exact times on every "step" interval. The PDPs are
+then accumulated into RRAs.
+
+The "heartbeat" defines the maximum acceptable interval between
+samples. If the interval between samples is less than "heartbeat",
+then an average rate is calculated and applied for that interval. If
+the interval between samples is longer than "heartbeat", then that
+entire interval is considered "unknown". Note that there are other
+things that can make a sample interval "unknown", such as the rate
+exceeding limits, or even an "unknown" input sample.
+
+The known rates during a PDP's "step" interval are used to calculate
+an average rate for that PDP. Also, if the total "unknown" time during
+the "step" interval exceeds the "heartbeat", the entire PDP is marked
+as "unknown". This means that a mixture of known and "unknown" sample
+times in a single PDP "step" may or may not add up to enough "unknown"
+time to exceed "heartbeat" and hence mark the whole PDP "unknown". So
+"heartbeat" is not only the maximum acceptable interval between
+samples, but also the maximum acceptable amount of "unknown" time per
+PDP (obviously this is only significant if you have "heartbeat" less
+than "step").
+
+The "heartbeat" can be short (unusual) or long (typical) relative to
+the "step" interval between PDPs. A short "heartbeat" means you
+require multiple samples per PDP, and if you don't get them mark the
+PDP unknown. A long heartbeat can span multiple "steps", which means
+it is acceptable to have multiple PDPs calculated from a single
+sample. An extreme example of this might be a "step" of 5 minutes and a
+"heartbeat" of one day, in which case a single sample every day will
+result in all the PDPs for that entire day period being set to the
+same average rate. I<-- Don Baarda E<lt>don.baarda@baesystems.comE<gt>>

+=head1 HOW TO MEASURE
+
+Here are a few hints on how to measure:
+
+=over
+
+
+=item Temperature
+
+Usually you have some type of meter you can read to get the temperature.
+The temperature is not really connected with a time. The only connection is
+that the temperature reading happened at a certain time. You can use the
+B<GAUGE> data source type for this. RRDtool will then record your reading
+together with the time.
+
+=item Mail Messages
+
+Assume you have a method to count the number of messages transported by
+your mailserver in a certain amount of time, giving you data like '5
+messages in the last 65 seconds'. If you look at the count of 5 like an
+B<ABSOLUTE> data type you can simply update the RRD with the number 5 and the
+end time of your monitoring period. RRDtool will then record the number of
+messages per second. If at some later stage you want to know the number of
+messages transported in a day, you can get the average messages per second
+from RRDtool for the day in question and multiply this number with the
+number of seconds in a day. Because all math is run with Doubles, the
+precision should be acceptable.
+
+=item It's always a Rate
+
+RRDtool stores rates in amount/second for COUNTER, DERIVE and ABSOLUTE
+data.  When you plot the data, you will get on the y axis
+amount/second which you might be tempted to convert to an absolute
+amount by multiplying by the delta-time between the points. RRDtool
+plots continuous data, and as such is not appropriate for plotting
+absolute amounts as for example "total bytes" sent and received in a
+router. What you probably want is plot rates that you can scale to
+bytes/hour, for example, or plot absolute amounts with another tool
+that draws bar-plots, where the delta-time is clear on the plot for
+each point (such that when you read the graph you see for example GB
+on the y axis, days on the x axis and one bar for each day).
+
+=back
+
+
+=head1 EXAMPLE
+
+ rrdtool create temperature.rrd --step 300 \
+  DS:temp:GAUGE:600:-273:5000 \
+  RRA:AVERAGE:0.5:1:1200 \
+  RRA:MIN:0.5:12:2400 \
+  RRA:MAX:0.5:12:2400 \
+  RRA:AVERAGE:0.5:12:2400
+
+This sets up an B<RRD> called F<temperature.rrd> which accepts one
+temperature value every 300 seconds. If no new data is supplied for
+more than 600 seconds, the temperature becomes I<*UNKNOWN*>.  The
+minimum acceptable value is -273 and the maximum is 5'000.
+
+A few archive areas are also defined. The first stores the
+temperatures supplied for 100 hours (1'200 * 300 seconds = 100
+hours). The second RRA stores the minimum temperature recorded over
+every hour (12 * 300 seconds = 1 hour), for 100 days (2'400 hours). The
+third and the fourth RRA's do the same for the maximum and
+average temperature, respectively.
+
+=head1 EXAMPLE 2
+
+ rrdtool create monitor.rrd --step 300        \
+   DS:ifOutOctets:COUNTER:1800:0:4294967295   \
+   RRA:AVERAGE:0.5:1:2016                     \
+   RRA:HWPREDICT:1440:0.1:0.0035:288
+
+This example is a monitor of a router interface. The first B<RRA> tracks the
+traffic flow in octets; the second B<RRA> generates the specialized
+functions B<RRAs> for aberrant behavior detection. Note that the I<rra-num>
+argument of HWPREDICT is missing, so the other B<RRAs> will implicitly be
+created with default parameter values. In this example, the forecasting
+algorithm baseline adapts quickly; in fact the most recent one hour of
+observations (each at 5 minute intervals) accounts for 75% of the baseline
+prediction. The linear trend forecast adapts much more slowly. Observations
+made during the last day (at 288 observations per day) account for only
+65% of the predicted linear trend. Note: these computations rely on an
+exponential smoothing formula described in the LISA 2000 paper.
+
+The seasonal cycle is one day (288 data points at 300 second intervals), and
+the seasonal adaption parameter will be set to 0.1. The RRD file will store 5
+days (1'440 data points) of forecasts and deviation predictions before wrap
+around. The file will store 1 day (a seasonal cycle) of 0-1 indicators in
+the FAILURES B<RRA>.
+
+The same RRD file and B<RRAs> are created with the following command,
+which explicitly creates all specialized function B<RRAs>.
+
+ rrdtool create monitor.rrd --step 300 \
+   DS:ifOutOctets:COUNTER:1800:0:4294967295 \
+   RRA:AVERAGE:0.5:1:2016 \
+   RRA:HWPREDICT:1440:0.1:0.0035:288:3 \
+   RRA:SEASONAL:288:0.1:2 \
+   RRA:DEVPREDICT:1440:5 \
+   RRA:DEVSEASONAL:288:0.1:2 \
+   RRA:FAILURES:288:7:9:5
+
+Of course, explicit creation need not replicate implicit create, a
+number of arguments could be changed.
+
+=head1 EXAMPLE 3
+
+ rrdtool create proxy.rrd --step 300 \
+   DS:Total:DERIVE:1800:0:U  \
+   DS:Duration:DERIVE:1800:0:U  \
+   DS:AvgReqDur:COMPUTE:Duration,Requests,0,EQ,1,Requests,IF,/ \
+   RRA:AVERAGE:0.5:1:2016
+
+This example is monitoring the average request duration during each 300 sec
+interval for requests processed by a web proxy during the interval.
+In this case, the proxy exposes two counters, the number of requests
+processed since boot and the total cumulative duration of all processed
+requests. Clearly these counters both have some rollover point, but using the
+DERIVE data source also handles the reset that occurs when the web proxy is
+stopped and restarted.
+
+In the B<RRD>, the first data source stores the requests per second rate
+during the interval. The second data source stores the total duration of all
+requests processed during the interval divided by 300. The COMPUTE data source
+divides each PDP of the AccumDuration by the corresponding PDP of
+TotalRequests and stores the average request duration. The remainder of the
+RPN expression handles the divide by zero case.

+               A single R\bRR\bRD\bD can accept input from several data sources (D\bDS\bS),
+               for example incoming and outgoing traffic on a specific commu-
+               nication line. With the D\bDS\bS configuration option you must define
+               some basic properties of each data source you want to store in
+               the R\bRR\bRD\bD.
+
+               _\bd_\bs_\b-_\bn_\ba_\bm_\be is the name you will use to reference this particular
+               data source from an R\bRR\bRD\bD. A _\bd_\bs_\b-_\bn_\ba_\bm_\be must be 1 to 19 characters
+               long in the characters [a-zA-Z0-9_].
+
+               _\bD_\bS_\bT defines the Data Source Type. The remaining arguments of a
+               data source entry depend on the data source type. For GAUGE,
+               COUNTER, DERIVE, and ABSOLUTE the format for a data source
+               entry is:
+
+               D\bDS\bS:\b:_\bd_\bs_\b-_\bn_\ba_\bm_\be:\b:_\bG_\bA_\bU_\bG_\bE _\b| _\bC_\bO_\bU_\bN_\bT_\bE_\bR _\b| _\bD_\bE_\bR_\bI_\bV_\bE _\b| _\bA_\bB_\bS_\bO_\bL_\bU_\bT_\bE:\b:_\bh_\be_\ba_\br_\bt_\b-

+               In order to decide which data source type to use, review the
+               definitions that follow. Also consult the section on "HOW TO
+               MEASURE" for further insight.
+
+               G\bGA\bAU\bUG\bGE\bE
+                   is for things like temperatures or number of people in a
+                   room or the value of a RedHat share.
+
+               C\bCO\bOU\bUN\bNT\bTE\bER\bR
+                   is for continuous incrementing counters like the ifInOctets
+                   counter in a router. The C\bCO\bOU\bUN\bNT\bTE\bER\bR data source assumes that
+                   the counter never decreases, except when a counter over-
+                   flows.  The update function takes the overflow into
+                   account.  The counter is stored as a per-second rate. When
+                   the counter overflows, RRDtool checks if the overflow hap-
+                   pened at the 32bit or 64bit border and acts accordingly by
+                   adding an appropriate value to the result.
+
+               D\bDE\bER\bRI\bIV\bVE\bE
+                   will store the derivative of the line going from the last
+                   to the current value of the data source. This can be useful
+                   for gauges, for example, to measure the rate of people
+                   entering or leaving a room. Internally, derive works
+                   exactly like COUNTER but without overflow checks. So if
+                   your counter does not reset at 32 or 64 bit you might want
+                   to use DERIVE and combine it with a MIN value of 0.
+
+                   NOTE on COUNTER vs DERIVE
+                       by Don Baarda <don.baarda@baesystems.com>
+
+                       If you cannot tolerate ever mistaking the occasional
+                       counter reset for a legitimate counter wrap, and would
+                       prefer "Unknowns" for all legitimate counter wraps and
+                       resets, always use DERIVE with min=0. Otherwise, using
+                       COUNTER with a suitable max will return correct values
+                       for all legitimate counter wraps, mark some counter
+                       resets as "Unknown", but can mistake some counter
+                       resets for a legitimate counter wrap.
+
+                       For a 5 minute step and 32-bit counter, the probability
+                       of mistaking a counter reset for a legitimate wrap is
+                       arguably about 0.8% per 1Mbps of maximum bandwidth.
+                       Note that this equates to 80% for 100Mbps interfaces,
+                       so for high bandwidth interfaces and a 32bit counter,
+                       DERIVE with min=0 is probably preferable. If you are
+                       using a 64bit counter, just about any max setting will
+                       eliminate the possibility of mistaking a reset for a
+                       counter wrap.
+
+               A\bAB\bBS\bSO\bOL\bLU\bUT\bTE\bE
+                   is for counters which get reset upon reading. This is used
+                   for fast counters which tend to overflow. So instead of
+                   reading them normally you reset them after every read to
+                   make sure you have a maximum time available before the next
+                   overflow. Another usage is for things you count like number
+                   of messages since the last update.
+
+               C\bCO\bOM\bMP\bPU\bUT\bTE\bE
+                   is for storing the result of a formula applied to other
+                   data sources in the R\bRR\bRD\bD. This data source is not supplied a
+                   value on update, but rather its Primary Data Points (PDPs)
+                   are computed from the PDPs of the data sources according to
+                   the rpn-expression that defines the formula. Consolidation
+                   functions are then applied normally to the PDPs of the COM-
+                   PUTE data source (that is the rpn-expression is only
+                   applied to generate PDPs). In database software, such data

+
+               _\bh_\be_\ba_\br_\bt_\bb_\be_\ba_\bt defines the maximum number of seconds that may pass
+               between two updates of this data source before the value of the
+               data source is assumed to be _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b*.
+
+               _\bm_\bi_\bn and _\bm_\ba_\bx define the expected range values for data supplied
+               by a data source. If _\bm_\bi_\bn and/or _\bm_\ba_\bx any value outside the
+               defined range will be regarded as _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b*. If you do not know
+               or care about min and max, set them to U for unknown. Note that
+               min and max always refer to the processed values of the DS. For
+               a traffic-C\bCO\bOU\bUN\bNT\bTE\bER\bR type DS this would be the maximum and minimum
+               data-rate expected from the device.

+
+               _\br_\bp_\bn_\b-_\be_\bx_\bp_\br_\be_\bs_\bs_\bi_\bo_\bn defines the formula used to compute the PDPs of
+               a COMPUTE data source from other data sources in the same
+               <RRD>. It is similar to defining a C\bCD\bDE\bEF\bF argument for the graph
+               command. Please refer to that manual page for a list and
+               description of RPN operations supported. For COMPUTE data
+               sources, the following RPN operations are not supported: COUNT,
+               PREV, TIME, and LTIME. In addition, in defining the RPN expres-
+               sion, the COMPUTE data source may only refer to the names of
+               data source listed previously in the create command. This is
+               similar to the restriction that C\bCD\bDE\bEF\bFs must refer only to D\bDE\bEF\bFs
+               and C\bCD\bDE\bEF\bFs previously defined in the same graph command.
+
+       R\bRR\bRA\bA:\b:_\bC_\bF:\b:_\bc_\bf _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs
+               The purpose of an R\bRR\bRD\bD is to store data in the round robin
+               archives (R\bRR\bRA\bA). An archive consists of a number of data values
+               or statistics for each of the defined data-sources (D\bDS\bS) and is
+               defined with an R\bRR\bRA\bA line.
+
+               When data is entered into an R\bRR\bRD\bD, it is first fit into time
+               slots of the length defined with the -\b-s\bs option, thus becoming a
+               _\bp_\br_\bi_\bm_\ba_\br_\by _\bd_\ba_\bt_\ba _\bp_\bo_\bi_\bn_\bt.
+
+               The data is also processed with the consolidation function (_\bC_\bF)
+               of the archive. There are several consolidation functions that
+               consolidate primary data points via an aggregate function:
+               A\bAV\bVE\bER\bRA\bAG\bGE\bE, M\bMI\bIN\bN, M\bMA\bAX\bX, L\bLA\bAS\bST\bT. The format of R\bRR\bRA\bA line for these con-
+               solidation functions is:
+
+               R\bRR\bRA\bA:\b:_\bA_\bV_\bE_\bR_\bA_\bG_\bE _\b| _\bM_\bI_\bN _\b| _\bM_\bA_\bX _\b| _\bL_\bA_\bS_\bT:\b:_\bx_\bf_\bf:\b:_\bs_\bt_\be_\bp_\bs:\b:_\br_\bo_\bw_\bs
+
+               _\bx_\bf_\bf The xfiles factor defines what part of a consolidation
+               interval may be made up from _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* data while the consoli-
+               dated value is still regarded as known. It is given as the
+               ratio of allowed _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* PDPs to the number of PDPs in the
+               interval. Thus, it ranges from 0 to 1 (exclusive).
+
+               _\bs_\bt_\be_\bp_\bs defines how many of these _\bp_\br_\bi_\bm_\ba_\br_\by _\bd_\ba_\bt_\ba _\bp_\bo_\bi_\bn_\bt_\bs are used to
+               build a _\bc_\bo_\bn_\bs_\bo_\bl_\bi_\bd_\ba_\bt_\be_\bd _\bd_\ba_\bt_\ba _\bp_\bo_\bi_\bn_\bt which then goes into the
+               archive.
+
+               _\br_\bo_\bw_\bs defines how many generations of data values are kept in an
+               R\bRR\bRA\bA.

+       In addition to the aggregate functions, there are a set of specialized
+       functions that enable R\bRR\bRD\bDt\bto\boo\bol\bl to provide data smoothing (via the Holt-
+       Winters forecasting algorithm), confidence bands, and the flagging
+       aberrant behavior in the data source time series:

+
+       These R\bRR\bRA\bAs\bs differ from the true consolidation functions in several
+       ways.  First, each of the R\bRR\bRA\bAs is updated once for every primary data
+       point.  Second, these R\bRR\bRA\bAs\bs are interdependent. To generate real-time
+       confidence bounds, a matched set of HWPREDICT, SEASONAL, DEVSEASONAL,
+       and DEVPREDICT must exist. Generating smoothed values of the primary
+       data points requires both a HWPREDICT R\bRR\bRA\bA and SEASONAL R\bRR\bRA\bA. Aberrant
+       behavior detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEA-
+       SONAL.
+
+       The actual predicted, or smoothed, values are stored in the HWPREDICT
+       R\bRR\bRA\bA. The predicted deviations are stored in DEVPREDICT (think a stan-
+       dard deviation which can be scaled to yield a confidence band). The
+       FAILURES R\bRR\bRA\bA stores binary indicators. A 1 marks the indexed observa-
+       tion as failure; that is, the number of confidence bounds violations in
+       the preceding window of observations met or exceeded a specified
+       threshold. An example of using these R\bRR\bRA\bAs\bs to graph confidence bounds
+       and failures appears in rrdgraph.
+
+       The SEASONAL and DEVSEASONAL R\bRR\bRA\bAs\bs store the seasonal coefficients for
+       the Holt-Winters forecasting algorithm and the seasonal deviations,
+       respectively.  There is one entry per observation time point in the
+       seasonal cycle. For example, if primary data points are generated every
+       five minutes and the seasonal cycle is 1 day, both SEASONAL and DEVSEA-
+       SONAL will have 288 rows.
+
+       In order to simplify the creation for the novice user, in addition to
+       supporting explicit creation of the HWPREDICT, SEASONAL, DEVPREDICT,
+       DEVSEASONAL, and FAILURES R\bRR\bRA\bAs\bs, the R\bRR\bRD\bDt\bto\boo\bol\bl create command supports
+       implicit creation of the other four when HWPREDICT is specified alone
+       and the final argument _\br_\br_\ba_\b-_\bn_\bu_\bm is omitted.
+
+       _\br_\bo_\bw_\bs specifies the length of the R\bRR\bRA\bA prior to wrap around. Remember
+       that there is a one-to-one correspondence between primary data points
+       and entries in these RRAs. For the HWPREDICT CF, _\br_\bo_\bw_\bs should be larger
+       than the _\bs_\be_\ba_\bs_\bo_\bn_\ba_\bl _\bp_\be_\br_\bi_\bo_\bd. If the DEVPREDICT R\bRR\bRA\bA is implicitly created,
+       the default number of rows is the same as the HWPREDICT _\br_\bo_\bw_\bs argument.
+       If the FAILURES R\bRR\bRA\bA is implicitly created, _\br_\bo_\bw_\bs will be set to the _\bs_\be_\ba_\b-
+       _\bs_\bo_\bn_\ba_\bl _\bp_\be_\br_\bi_\bo_\bd argument of the HWPREDICT R\bRR\bRA\bA. Of course, the R\bRR\bRD\bDt\bto\boo\bol\bl
+       _\br_\be_\bs_\bi_\bz_\be command is available if these defaults are not sufficient and
+       the creator wishes to avoid explicit creations of the other specialized
+       function R\bRR\bRA\bAs\bs.
+
+       _\bs_\be_\ba_\bs_\bo_\bn_\ba_\bl _\bp_\be_\br_\bi_\bo_\bd specifies the number of primary data points in a sea-
+       sonal cycle. If SEASONAL and DEVSEASONAL are implicitly created, this
+       argument for those R\bRR\bRA\bAs\bs is set automatically to the value specified by
+       HWPREDICT. If they are explicitly created, the creator should verify
+       that all three _\bs_\be_\ba_\bs_\bo_\bn_\ba_\bl _\bp_\be_\br_\bi_\bo_\bd arguments agree.
+
+       _\ba_\bl_\bp_\bh_\ba is the adaption parameter of the intercept (or baseline) coeffi-
+       cient in the Holt-Winters forecasting algorithm. See rrdtool for a
+       description of this algorithm. _\ba_\bl_\bp_\bh_\ba must lie between 0 and 1. A value
+       closer to 1 means that more recent observations carry greater weight in
+       predicting the baseline component of the forecast. A value closer to 0
+       means that past history carries greater weight in predicting the base-
+       line component.
+
+       _\bb_\be_\bt_\ba is the adaption parameter of the slope (or linear trend) coeffi-
+       cient in the Holt-Winters forecasting algorithm. _\bb_\be_\bt_\ba must lie between
+       0 and 1 and plays the same role as _\ba_\bl_\bp_\bh_\ba with respect to the predicted
+       linear trend.
+
+       _\bg_\ba_\bm_\bm_\ba is the adaption parameter of the seasonal coefficients in the
+       Holt-Winters forecasting algorithm (HWPREDICT) or the adaption parame-
+       ter in the exponential smoothing update of the seasonal deviations. It
+       must lie between 0 and 1. If the SEASONAL and DEVSEASONAL R\bRR\bRA\bAs\bs are cre-
+       ated implicitly, they will both have the same value for _\bg_\ba_\bm_\bm_\ba: the
+       value specified for the HWPREDICT _\ba_\bl_\bp_\bh_\ba argument. Note that because
+       there is one seasonal coefficient (or deviation) for each time point
+       during the seasonal cycle, the adaptation rate is much slower than the
+       baseline. Each seasonal coefficient is only updated (or adapts) when
+       the observed value occurs at the offset in the seasonal cycle corre-
+       sponding to that coefficient.
+
+       If SEASONAL and DEVSEASONAL R\bRR\bRA\bAs\bs are created explicitly, _\bg_\ba_\bm_\bm_\ba need not
+       be the same for both. Note that _\bg_\ba_\bm_\bm_\ba can also be changed via the R\bRR\bRD\bD-\b-
+       t\bto\boo\bol\bl _\bt_\bu_\bn_\be command.
+
+       _\br_\br_\ba_\b-_\bn_\bu_\bm provides the links between related R\bRR\bRA\bAs\bs. If HWPREDICT is speci-
+       fied alone and the other R\bRR\bRA\bAs\bs are created implicitly, then there is no
+       need to worry about this argument. If R\bRR\bRA\bAs\bs are created explicitly, then
+       carefully pay attention to this argument. For each R\bRR\bRA\bA which includes
+       this argument, there is a dependency between that R\bRR\bRA\bA and another R\bRR\bRA\bA.
+       The _\br_\br_\ba_\b-_\bn_\bu_\bm argument is the 1-based index in the order of R\bRR\bRA\bA creation
+       (that is, the order they appear in the _\bc_\br_\be_\ba_\bt_\be command). The dependent
+       R\bRR\bRA\bA for each R\bRR\bRA\bA requiring the _\br_\br_\ba_\b-_\bn_\bu_\bm argument is listed here:
+
+       ·   HWPREDICT _\br_\br_\ba_\b-_\bn_\bu_\bm is the index of the SEASONAL R\bRR\bRA\bA.
+
+       ·   SEASONAL _\br_\br_\ba_\b-_\bn_\bu_\bm is the index of the HWPREDICT R\bRR\bRA\bA.
+
+       ·   DEVPREDICT _\br_\br_\ba_\b-_\bn_\bu_\bm is the index of the DEVSEASONAL R\bRR\bRA\bA.
+
+       ·   DEVSEASONAL _\br_\br_\ba_\b-_\bn_\bu_\bm is the index of the HWPREDICT R\bRR\bRA\bA.
+
+       ·   FAILURES _\br_\br_\ba_\b-_\bn_\bu_\bm is the index of the DEVSEASONAL R\bRR\bRA\bA.
+
+       _\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd is the minimum number of violations (observed values outside
+       the confidence bounds) within a window that constitutes a failure. If
+       the FAILURES R\bRR\bRA\bA is implicitly created, the default value is 7.
+
+       _\bw_\bi_\bn_\bd_\bo_\bw _\bl_\be_\bn_\bg_\bt_\bh is the number of time points in the window. Specify an
+       integer greater than or equal to the threshold and less than or equal
+       to 28.  The time interval this window represents depends on the inter-
+       val between primary data points. If the FAILURES R\bRR\bRA\bA is implicitly cre-
+       ated, the default value is 9.

+       Here is an explanation by Don Baarda on the inner workings of RRDtool.
+       It may help you to sort out why all this *UNKNOWN* data is popping up
+       in your databases:
+
+       RRDtool gets fed samples at arbitrary times. From these it builds Pri-
+       mary Data Points (PDPs) at exact times on every "step" interval. The
+       PDPs are then accumulated into RRAs.
+
+       The "heartbeat" defines the maximum acceptable interval between sam-
+       ples. If the interval between samples is less than "heartbeat", then an
+       average rate is calculated and applied for that interval. If the inter-
+       val between samples is longer than "heartbeat", then that entire inter-
+       val is considered "unknown". Note that there are other things that can
+       make a sample interval "unknown", such as the rate exceeding limits, or
+       even an "unknown" input sample.
+
+       The known rates during a PDP's "step" interval are used to calculate an
+       average rate for that PDP. Also, if the total "unknown" time during the
+       "step" interval exceeds the "heartbeat", the entire PDP is marked as
+       "unknown". This means that a mixture of known and "unknown" sample
+       times in a single PDP "step" may or may not add up to enough "unknown"
+       time to exceed "heartbeat" and hence mark the whole PDP "unknown". So
+       "heartbeat" is not only the maximum acceptable interval between sam-
+       ples, but also the maximum acceptable amount of "unknown" time per PDP
+       (obviously this is only significant if you have "heartbeat" less than
+       "step").
+
+       The "heartbeat" can be short (unusual) or long (typical) relative to
+       the "step" interval between PDPs. A short "heartbeat" means you require
+       multiple samples per PDP, and if you don't get them mark the PDP
+       unknown. A long heartbeat can span multiple "steps", which means it is
+       acceptable to have multiple PDPs calculated from a single sample. An
+       extreme example of this might be a "step" of 5 minutes and a "heart-
+       beat" of one day, in which case a single sample every day will result
+       in all the PDPs for that entire day period being set to the same aver-
+       age rate. _\b-_\b- _\bD_\bo_\bn _\bB_\ba_\ba_\br_\bd_\ba _\b<_\bd_\bo_\bn_\b._\bb_\ba_\ba_\br_\bd_\ba_\b@_\bb_\ba_\be_\bs_\by_\bs_\bt_\be_\bm_\bs_\b._\bc_\bo_\bm_\b>

+       Here are a few hints on how to measure:
+
+       Temperature
+           Usually you have some type of meter you can read to get the temper-
+           ature.  The temperature is not really connected with a time. The
+           only connection is that the temperature reading happened at a cer-
+           tain time. You can use the G\bGA\bAU\bUG\bGE\bE data source type for this. RRDtool
+           will then record your reading together with the time.
+
+       Mail Messages
+           Assume you have a method to count the number of messages trans-
+           ported by your mailserver in a certain amount of time, giving you
+           data like '5 messages in the last 65 seconds'. If you look at the
+           count of 5 like an A\bAB\bBS\bSO\bOL\bLU\bUT\bTE\bE data type you can simply update the RRD
+           with the number 5 and the end time of your monitoring period. RRD-
+           tool will then record the number of messages per second. If at some
+           later stage you want to know the number of messages transported in
+           a day, you can get the average messages per second from RRDtool for
+           the day in question and multiply this number with the number of
+           seconds in a day. Because all math is run with Doubles, the preci-
+           sion should be acceptable.
+
+       It's always a Rate
+           RRDtool stores rates in amount/second for COUNTER, DERIVE and ABSO-
+           LUTE data.  When you plot the data, you will get on the y axis
+           amount/second which you might be tempted to convert to an absolute
+           amount by multiplying by the delta-time between the points. RRDtool
+           plots continuous data, and as such is not appropriate for plotting
+           absolute amounts as for example "total bytes" sent and received in
+           a router. What you probably want is plot rates that you can scale
+           to bytes/hour, for example, or plot absolute amounts with another
+           tool that draws bar-plots, where the delta-time is clear on the
+           plot for each point (such that when you read the graph you see for
+           example GB on the y axis, days on the x axis and one bar for each
+           day).

+

+       ture value every 300 seconds. If no new data is supplied for more than
+       600 seconds, the temperature becomes _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b*.  The minimum acceptable
+       value is -273 and the maximum is 5'000.
+
+       A few archive areas are also defined. The first stores the temperatures
+       supplied for 100 hours (1'200 * 300 seconds = 100 hours). The second
+       RRA stores the minimum temperature recorded over every hour (12 * 300
+       seconds = 1 hour), for 100 days (2'400 hours). The third and the fourth
+       RRA's do the same for the maximum and average temperature, respec-
+       tively.

+          RRA:HWPREDICT:1440:0.1:0.0035:288
+
+       This example is a monitor of a router interface. The first R\bRR\bRA\bA tracks
+       the traffic flow in octets; the second R\bRR\bRA\bA generates the specialized
+       functions R\bRR\bRA\bAs\bs for aberrant behavior detection. Note that the _\br_\br_\ba_\b-_\bn_\bu_\bm
+       argument of HWPREDICT is missing, so the other R\bRR\bRA\bAs\bs will implicitly be
+       created with default parameter values. In this example, the forecasting
+       algorithm baseline adapts quickly; in fact the most recent one hour of
+       observations (each at 5 minute intervals) accounts for 75% of the base-
+       line prediction. The linear trend forecast adapts much more slowly.
+       Observations made during the last day (at 288 observations per day)
+       account for only 65% of the predicted linear trend. Note: these compu-
+       tations rely on an exponential smoothing formula described in the LISA
+       2000 paper.
+
+       The seasonal cycle is one day (288 data points at 300 second inter-
+       vals), and the seasonal adaption parameter will be set to 0.1. The RRD
+       file will store 5 days (1'440 data points) of forecasts and deviation
+       predictions before wrap around. The file will store 1 day (a seasonal
+       cycle) of 0-1 indicators in the FAILURES R\bRR\bRA\bA.
+
+       The same RRD file and R\bRR\bRA\bAs\bs are created with the following command,
+       which explicitly creates all specialized function R\bRR\bRA\bAs\bs.

+       ber of arguments could be changed.

+          DS:AvgReqDur:COMPUTE:Duration,Requests,0,EQ,1,Requests,IF,/ \
+          RRA:AVERAGE:0.5:1:2016
+
+       This example is monitoring the average request duration during each 300
+       sec interval for requests processed by a web proxy during the interval.
+       In this case, the proxy exposes two counters, the number of requests
+       processed since boot and the total cumulative duration of all processed
+       requests. Clearly these counters both have some rollover point, but
+       using the DERIVE data source also handles the reset that occurs when
+       the web proxy is stopped and restarted.
+
+       In the R\bRR\bRD\bD, the first data source stores the requests per second rate
+       during the interval. The second data source stores the total duration
+       of all requests processed during the interval divided by 300. The COM-
+       PUTE data source divides each PDP of the AccumDuration by the corre-
+       sponding PDP of TotalRequests and stores the average request duration.
+       The remainder of the RPN expression handles the divide by zero case.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBfetch\fR function is normally used internally by the graph
+function to get data from \fB\s-1RRD\s0\fRs. \fBfetch\fR will analyze the \fB\s-1RRD\s0\fR
+and try to retrieve the data in the resolution requested.
+The data fetched is printed to stdout. \fI*UNKNOWN*\fR data is often
+represented by the string \*(L"NaN\*(R" depending on your \s-1OS\s0's printf
+function.
+.IP "\fIfilename\fR" 8
+.IX Item "filename"
+the name of the \fB\s-1RRD\s0\fR you want to fetch the data from.
+.IP "\fI\s-1CF\s0\fR" 8
+.IX Item "CF"
+the consolidation function that is applied to the data you
+want to fetch (\s-1AVERAGE\s0,MIN,MAX,LAST)
+.IP "\fB\-\-resolution\fR|\fB\-r\fR \fIresolution\fR (default is the highest resolution)" 8
+.IX Item "--resolution|-r resolution (default is the highest resolution)"
+the interval you want the values to have (seconds per
+value). \fBrrdfetch\fR will try to match your request, but it will return
+data even if no absolute match is possible. \fB\s-1NB\s0.\fR See note below.
+.IP "\fB\-\-start\fR|\fB\-s\fR \fIstart\fR (default end\-1day)" 8
+.IX Item "--start|-s start (default end-1day)"
+start of the time series. A time in seconds since epoch (1970\-01\-01)
+is required. Negative numbers are relative to the current time. By default,
+one day worth of data will be fetched. See also AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0
+section for a detailed explanation on  ways to specify the start time.
+.IP "\fB\-\-end\fR|\fB\-e\fR \fIend\fR (default now)" 8
+.IX Item "--end|-e end (default now)"
+the end of the time series in seconds since epoch. See also AT-STYLE
+\&\s-1TIME\s0 \s-1SPECIFICATION\s0 section for a detailed explanation of how to
+specify the end time.
+.Sh "\s-1RESOLUTION\s0 \s-1INTERVAL\s0"
+.IX Subsection "RESOLUTION INTERVAL"
+In order to get RRDtool to fetch anything other than the finest resolution \s-1RRA\s0
+\&\fBboth\fR the start and end time must be specified on boundaries that are
+multiples of the desired resolution. Consider the following example:
+.PP
+.Vb 7
+\& rrdtool create subdata.rrd \-s 10 DS:ds0:GAUGE:300:0:U \e
+\&  RRA:AVERAGE:0.5:30:3600 \e
+\&  RRA:AVERAGE:0.5:90:1200 \e
+\&  RRA:AVERAGE:0.5:360:1200 \e
+\&  RRA:MAX:0.5:360:1200 \e
+\&  RRA:AVERAGE:0.5:8640:600 \e
+\&  RRA:MAX:0.5:8640:600
+.Ve
+.PP
+This \s-1RRD\s0 collects data every 10 seconds and stores its averages over 5
+minutes, 15 minutes, 1 hour, and 1 day, as well as the maxima for 1 hour
+and 1 day.
+.PP
+Consider now that you want to fetch the 15 minute average data for the
+last hour.  You might try
+.PP
+.Vb 1
+\& rrdtool fetch subdata.rrd AVERAGE \-r 900 \-s \-1h
+.Ve
+.PP
+However, this will almost always result in a time series that is
+\&\fB\s-1NOT\s0\fR in the 15 minute \s-1RRA\s0. Therefore, the highest resolution \s-1RRA\s0,
+i.e. 5 minute averages, will be chosen which in this case is not
+what you want.
+.PP
+Hence, make sure that
+.IP "1." 3
+both start and end time are a multiple of 900
+.IP "2." 3
+both start and end time are within the desired \s-1RRA\s0
+.PP
+So, if time now is called \*(L"t\*(R", do
+.PP
+.Vb 3
+\& end time == int(t/900)*900,
+\& start time == end time \- 1hour,
+\& resolution == 900.
+.Ve
+.PP
+Using the bash shell, this could look be:
+.PP
+.Vb 4
+\& TIME=$(date +%s)
+\& RRDRES=900
+\& rrdtool fetch subdata.rrd AVERAGE \-r $RRDRES \e
+\&    \-e $(($TIME/$RRDRES*$RRDRES)) \-s e\-1h
+.Ve
+.PP
+Or in Perl:
+.PP
+.Vb 3
+\& perl \-e '$ctime = time; $rrdres = 900; \e
+\&          system "rrdtool fetch subdata.rrd AVERAGE \e
+\&                  \-r $rrdres \-e @{[int($ctime/$rrdres)*$rrdres]} \-s e\-1h"'
+.Ve
+.Sh "AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0"
+.IX Subsection "AT-STYLE TIME SPECIFICATION"
+Apart from the traditional \fISeconds since epoch\fR, RRDtool does also
+understand at-style time specification. The specification is called
+\&\*(L"at\-style\*(R" after the Unix command \fIat\fR\|(1) that has moderately complex
+ways to specify time to run your job at a certain date and time. The
+at-style specification consists of two parts: the \fB\s-1TIME\s0 \s-1REFERENCE\s0\fR
+specification and the \fB\s-1TIME\s0 \s-1OFFSET\s0\fR specification.
+.Sh "\s-1TIME\s0 \s-1REFERENCE\s0 \s-1SPECIFICATION\s0"
+.IX Subsection "TIME REFERENCE SPECIFICATION"
+The time reference specification is used, well, to establish a reference
+moment in time (to which the time offset is then applied to). When present,
+it should come first, when omitted, it defaults to \fBnow\fR. On its own part,
+time reference consists of a \fItime-of-day\fR reference (which should come
+first, if present) and a \fIday\fR reference.
+.PP
+The \fItime-of-day\fR can be specified as \fB\s-1HH:MM\s0\fR, \fB\s-1HH\s0.MM\fR,
+or just \fB\s-1HH\s0\fR. You can suffix it with \fBam\fR or \fBpm\fR or use
+24\-hours clock. Some special times of day are understood as well,
+including \fBmidnight\fR (00:00), \fBnoon\fR (12:00) and British
+\&\fBteatime\fR (16:00).
+.PP
+The \fIday\fR can be specified as \fImonth-name\fR \fIday-of-the-month\fR and
+optional a 2\- or 4\-digit \fIyear\fR number (e.g. March 8 1999). Alternatively,
+you can use \fIday-of-week-name\fR (e.g. Monday), or one of the words:
+\&\fByesterday\fR, \fBtoday\fR, \fBtomorrow\fR. You can also specify the \fIday\fR as a
+full date in several numerical formats, including \fBMM/DD/[\s-1YY\s0]YY\fR,
+\&\fB\s-1DD\s0.MM.[\s-1YY\s0]YY\fR, or \fB\s-1YYYYMMDD\s0\fR.
+.PP
+\&\fI\s-1NOTE1\s0\fR: this is different from the original \fIat\fR\|(1) behavior, where a
+single-number date is interpreted as MMDD[\s-1YY\s0]YY.
+.PP
+\&\fI\s-1NOTE2\s0\fR: if you specify the \fIday\fR in this way, the \fItime-of-day\fR is
+\&\s-1REQUIRED\s0 as well.
+.PP
+Finally, you can use the words \fBnow\fR, \fBstart\fR, or \fBend\fR as your time
+reference. \fBNow\fR refers to the current moment (and is also the default
+time reference). \fBStart\fR (\fBend\fR) can be used to specify a time
+relative to the start (end) time for those tools that use these
+categories (\fBrrdfetch\fR, rrdgraph).
+.PP
+Month and day of the week names can be used in their naturally
+abbreviated form (e.g., Dec for December, Sun for Sunday, etc.). The
+words \fBnow\fR, \fBstart\fR, \fBend\fR can be abbreviated as \fBn\fR, \fBs\fR, \fBe\fR.
+.Sh "\s-1TIME\s0 \s-1OFFSET\s0 \s-1SPECIFICATION\s0"
+.IX Subsection "TIME OFFSET SPECIFICATION"
+The time offset specification is used to add/subtract certain time
+intervals to/from the time reference moment. It consists of a \fIsign\fR
+(\fB+\fR\ or\ \fB\-\fR) and an \fIamount\fR. The following time units can be
+used to specify the \fIamount\fR: \fByears\fR, \fBmonths\fR, \fBweeks\fR, \fBdays\fR,
+\&\fBhours\fR, \fBminutes\fR, or \fBseconds\fR. These units can be used in
+singular or plural form, and abbreviated naturally or to a single
+letter (e.g. +3days, \-1wk, \-3y). Several time units can be combined
+(e.g., \-5mon1w2d) or concatenated (e.g., \-5h45min = \-5h\-45min =
+\&\-6h+15min = \-7h+1h30m\-15min, etc.)
+.PP
+\&\fI\s-1NOTE3\s0\fR: If you specify time offset in days, weeks, months, or years,
+you will end with the time offset that may vary depending on your time
+reference, because all those time units have no single well defined
+time interval value (1\ year contains either 365 or 366 days, 1\ month
+is 28 to 31 days long, and even 1\ day may be not equal to 24 hours
+twice a year, when DST-related clock adjustments take place).
+To cope with this, when you use days, weeks, months, or years
+as your time offset units your time reference date is adjusted
+accordingly without too much further effort to ensure anything
+about it (in the hope that \fImktime\fR\|(3) will take care of this later).
+This may lead to some surprising (or even invalid!) results,
+e.g. 'May\ 31\ \-1month' = 'Apr\ 31' (meaningless) = 'May\ 1'
+(after \fImktime\fR\|(3) normalization); in the \s-1EET\s0 timezone
+\&'3:30am Mar 29 1999 \-1 day' yields '3:30am Mar 28 1999' (Sunday)
+which is an invalid time/date combination (because of 3am \-> 4am \s-1DST\s0
+forward clock adjustment, see the below example).
+.PP
+In contrast, hours, minutes, and seconds are well defined time
+intervals, and these are guaranteed to always produce time offsets
+exactly as specified (e.g. for \s-1EET\s0 timezone, '8:00\ Mar\ 27\ 1999\ +2\ days' = '8:00\ Mar\ 29\ 1999', but since there is 1\-hour \s-1DST\s0 forward
+clock adjustment that occurs around 3:00\ Mar\ 28\ 1999, the actual
+time interval between 8:00\ Mar\ 27\ 1999 and 8:00\ Mar\ 29\ 1999
+equals 47 hours; on the other hand, '8:00\ Mar\ 27\ 1999\ +48\ hours' =
+\&'9:00\ Mar\ 29\ 1999', as expected)
+.PP
+\&\fI\s-1NOTE4\s0\fR: The single-letter abbreviation for both \fBmonths\fR and \fBminutes\fR
+is \fBm\fR. To disambiguate them, the parser tries to read your mind\ :)
+by applying the following two heuristics:
+.IP "1" 3
+.IX Item "1"
+If \fBm\fR is used in context of (i.e. right after the) years,
+months, weeks, or days it is assumed to mean \fBmonths\fR, while
+in the context of hours, minutes, and seconds it means minutes.
+(e.g., in \-1y6m or +3w1m \fBm\fR is interpreted as \fBmonths\fR, while in
+\&\-3h20m or +5s2m \fBm\fR the parser decides for \fBminutes\fR).
+.IP "2" 3
+.IX Item "2"
+Out of context (i.e. right after the \fB+\fR or \fB\-\fR sign) the
+meaning of \fBm\fR is guessed from the number it directly follows.
+Currently, if the number's absolute value is below 25 it is assumed
+that \fBm\fR means \fBmonths\fR, otherwise it is treated as \fBminutes\fR.
+(e.g., \-25m == \-25 minutes, while +24m == +24 months)
+.PP
+\&\fIFinal \s-1NOTES\s0\fR: Time specification is case\-insensitive.
+Whitespace can be inserted freely or omitted altogether.
+There are, however, cases when whitespace is required
+(e.g., 'midnight\ Thu'). In this case you should either quote the
+whole phrase to prevent it from being taken apart by your shell or use
+\&'_' (underscore) or ',' (comma) which also count as whitespace
+(e.g., midnight_Thu or midnight,Thu).

+<h2><a name="resolution_interval">RESOLUTION INTERVAL</a></h2>
+<p>In order to get RRDtool to fetch anything other than the finest resolution RRA
+<strong>both</strong> the start and end time must be specified on boundaries that are
+multiples of the desired resolution. Consider the following example:</p>
+<pre>
+ rrdtool create subdata.rrd -s 10 DS:ds0:GAUGE:300:0:U \
+  RRA:AVERAGE:0.5:30:3600 \
+  RRA:AVERAGE:0.5:90:1200 \
+  RRA:AVERAGE:0.5:360:1200 \
+  RRA:MAX:0.5:360:1200 \
+  RRA:AVERAGE:0.5:8640:600 \
+  RRA:MAX:0.5:8640:600</pre>
+<p>This RRD collects data every 10 seconds and stores its averages over 5
+minutes, 15 minutes, 1 hour, and 1 day, as well as the maxima for 1 hour
+and 1 day.</p>
+<p>Consider now that you want to fetch the 15 minute average data for the
+last hour.  You might try</p>
+<pre>
+ rrdtool fetch subdata.rrd AVERAGE -r 900 -s -1h</pre>
+<p>However, this will almost always result in a time series that is
+<strong>NOT</strong> in the 15 minute RRA. Therefore, the highest resolution RRA,
+i.e. 5 minute averages, will be chosen which in this case is not
+what you want.</p>
+<p>Hence, make sure that</p>
+<ol>
+<li>
+<p>both start and end time are a multiple of 900</p>
+</li>
+<li>
+<p>both start and end time are within the desired RRA</p>
+</li>
+</ol>
+<p>So, if time now is called ``t'', do</p>
+<pre>
+ end time == int(t/900)*900,
+ start time == end time - 1hour,
+ resolution == 900.</pre>
+<p>Using the bash shell, this could look be:</p>
+<pre>
+ TIME=$(date +%s)
+ RRDRES=900
+ rrdtool fetch subdata.rrd AVERAGE -r $RRDRES \
+    -e $(($TIME/$RRDRES*$RRDRES)) -s e-1h</pre>
+<p>Or in Perl:</p>
+<pre>
+ perl -e '$ctime = time; $rrdres = 900; \
+          system &quot;rrdtool fetch subdata.rrd AVERAGE \
+                  -r $rrdres -e @{[int($ctime/$rrdres)*$rrdres]} -s e-1h&quot;'</pre>
+<p>
+</p>
+<h2><a name="atstyle_time_specification">AT-STYLE TIME SPECIFICATION</a></h2>
+<p>Apart from the traditional <em>Seconds since epoch</em>, RRDtool does also
+understand at-style time specification. The specification is called
+``at-style'' after the Unix command <code>at(1)</code> that has moderately complex
+ways to specify time to run your job at a certain date and time. The
+at-style specification consists of two parts: the <strong>TIME REFERENCE</strong>
+specification and the <strong>TIME OFFSET</strong> specification.</p>
+<p>
+</p>
+<h2><a name="time_reference_specification">TIME REFERENCE SPECIFICATION</a></h2>
+<p>The time reference specification is used, well, to establish a reference
+moment in time (to which the time offset is then applied to). When present,
+it should come first, when omitted, it defaults to <strong>now</strong>. On its own part,
+time reference consists of a <em>time-of-day</em> reference (which should come
+first, if present) and a <em>day</em> reference.</p>
+<p>The <em>time-of-day</em> can be specified as <strong>HH:MM</strong>, <strong>HH.MM</strong>,
+or just <strong>HH</strong>. You can suffix it with <strong>am</strong> or <strong>pm</strong> or use
+24-hours clock. Some special times of day are understood as well,
+including <strong>midnight</strong> (00:00), <strong>noon</strong> (12:00) and British
+<strong>teatime</strong> (16:00).</p>
+<p>The <em>day</em> can be specified as <em>month-name</em> <em>day-of-the-month</em> and
+optional a 2- or 4-digit <em>year</em> number (e.g. March 8 1999). Alternatively,
+you can use <em>day-of-week-name</em> (e.g. Monday), or one of the words:
+<strong>yesterday</strong>, <strong>today</strong>, <strong>tomorrow</strong>. You can also specify the <em>day</em> as a
+full date in several numerical formats, including <strong>MM/DD/[YY]YY</strong>,
+<strong>DD.MM.[YY]YY</strong>, or <strong>YYYYMMDD</strong>.</p>
+<p><em>NOTE1</em>: this is different from the original <code>at(1)</code> behavior, where a
+single-number date is interpreted as MMDD[YY]YY.</p>
+<p><em>NOTE2</em>: if you specify the <em>day</em> in this way, the <em>time-of-day</em> is
+REQUIRED as well.</p>
+<p>Finally, you can use the words <strong>now</strong>, <strong>start</strong>, or <strong>end</strong> as your time
+reference. <strong>Now</strong> refers to the current moment (and is also the default
+time reference). <strong>Start</strong> (<strong>end</strong>) can be used to specify a time
+relative to the start (end) time for those tools that use these
+categories (<strong>rrdfetch</strong>, <a href="././rrdgraph.html">the rrdgraph manpage</a>).</p>
+<p>Month and day of the week names can be used in their naturally
+abbreviated form (e.g., Dec for December, Sun for Sunday, etc.). The
+words <strong>now</strong>, <strong>start</strong>, <strong>end</strong> can be abbreviated as <strong>n</strong>, <strong>s</strong>, <strong>e</strong>.</p>
+<p>
+</p>
+<h2><a name="time_offset_specification">TIME OFFSET SPECIFICATION</a></h2>
+<p>The time offset specification is used to add/subtract certain time
+intervals to/from the time reference moment. It consists of a <em>sign</em>
+(<strong>+</strong>&nbsp;or&nbsp;<strong>-</strong>) and an <em>amount</em>. The following time units can be
+used to specify the <em>amount</em>: <strong>years</strong>, <strong>months</strong>, <strong>weeks</strong>, <strong>days</strong>,
+<strong>hours</strong>, <strong>minutes</strong>, or <strong>seconds</strong>. These units can be used in
+singular or plural form, and abbreviated naturally or to a single
+letter (e.g. +3days, -1wk, -3y). Several time units can be combined
+(e.g., -5mon1w2d) or concatenated (e.g., -5h45min = -5h-45min =
+-6h+15min = -7h+1h30m-15min, etc.)</p>
+<p><em>NOTE3</em>: If you specify time offset in days, weeks, months, or years,
+you will end with the time offset that may vary depending on your time
+reference, because all those time units have no single well defined
+time interval value (1&nbsp;year contains either 365 or 366 days, 1&nbsp;month
+is 28 to 31 days long, and even 1&nbsp;day may be not equal to 24 hours
+twice a year, when DST-related clock adjustments take place).
+To cope with this, when you use days, weeks, months, or years
+as your time offset units your time reference date is adjusted
+accordingly without too much further effort to ensure anything
+about it (in the hope that <code>mktime(3)</code> will take care of this later).
+This may lead to some surprising (or even invalid!) results,
+e.g. 'May&nbsp;31&nbsp;-1month' = 'Apr&nbsp;31' (meaningless) = 'May&nbsp;1'
+(after <code>mktime(3)</code> normalization); in the EET timezone
+'3:30am Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' (Sunday)
+which is an invalid time/date combination (because of 3am -&gt; 4am DST
+forward clock adjustment, see the below example).</p>
+<p>In contrast, hours, minutes, and seconds are well defined time
+intervals, and these are guaranteed to always produce time offsets
+exactly as specified (e.g. for EET timezone, '8:00&nbsp;Mar&nbsp;27&nbsp;1999&nbsp;+2
+days' = '8:00&nbsp;Mar&nbsp;29&nbsp;1999', but since there is 1-hour DST forward
+clock adjustment that occurs around 3:00&nbsp;Mar&nbsp;28&nbsp;1999, the actual
+time interval between 8:00&nbsp;Mar&nbsp;27&nbsp;1999 and 8:00&nbsp;Mar&nbsp;29&nbsp;1999
+equals 47 hours; on the other hand, '8:00&nbsp;Mar&nbsp;27&nbsp;1999&nbsp;+48&nbsp;hours' =
+'9:00&nbsp;Mar&nbsp;29&nbsp;1999', as expected)</p>
+<p><em>NOTE4</em>: The single-letter abbreviation for both <strong>months</strong> and <strong>minutes</strong>
+is <strong>m</strong>. To disambiguate them, the parser tries to read your mind&nbsp;:)
+by applying the following two heuristics:</p>
+<ol>
+<li>
+<p>If <strong>m</strong> is used in context of (i.e. right after the) years,
+months, weeks, or days it is assumed to mean <strong>months</strong>, while
+in the context of hours, minutes, and seconds it means minutes.
+(e.g., in -1y6m or +3w1m <strong>m</strong> is interpreted as <strong>months</strong>, while in
+-3h20m or +5s2m <strong>m</strong> the parser decides for <strong>minutes</strong>).</p>
+</li>
+<li>
+<p>Out of context (i.e. right after the <strong>+</strong> or <strong>-</strong> sign) the
+meaning of <strong>m</strong> is guessed from the number it directly follows.
+Currently, if the number's absolute value is below 25 it is assumed
+that <strong>m</strong> means <strong>months</strong>, otherwise it is treated as <strong>minutes</strong>.
+(e.g., -25m == -25 minutes, while +24m == +24 months)</p>
+</li>
+</ol>
+<p><em>Final NOTES</em>: Time specification is case-insensitive.
+Whitespace can be inserted freely or omitted altogether.
+There are, however, cases when whitespace is required
+(e.g., 'midnight&nbsp;Thu'). In this case you should either quote the
+whole phrase to prevent it from being taken apart by your shell or use
+'_' (underscore) or ',' (comma) which also count as whitespace
+(e.g., midnight_Thu or midnight,Thu).</p>

+=head1 NAME
+
+rrdfetch - Fetch data from an RRD.
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<fetch> I<filename> I<CF>
+S<[B<--resolution>|B<-r> I<resolution>]>
+S<[B<--start>|B<-s> I<start>]>
+S<[B<--end>|B<-e> I<end>]>
+
+=head1 DESCRIPTION
+
+The B<fetch> function is normally used internally by the graph
+function to get data from B<RRD>s. B<fetch> will analyze the B<RRD>
+and try to retrieve the data in the resolution requested.
+The data fetched is printed to stdout. I<*UNKNOWN*> data is often
+represented by the string "NaN" depending on your OS's printf
+function.
+
+=over 8
+
+=item I<filename>
+
+the name of the B<RRD> you want to fetch the data from.
+
+=item I<CF>
+
+the consolidation function that is applied to the data you
+want to fetch (AVERAGE,MIN,MAX,LAST)
+
+=item B<--resolution>|B<-r> I<resolution> (default is the highest resolution)
+
+the interval you want the values to have (seconds per
+value). B<rrdfetch> will try to match your request, but it will return
+data even if no absolute match is possible. B<NB.> See note below.
+
+=item B<--start>|B<-s> I<start> (default end-1day)
+
+start of the time series. A time in seconds since epoch (1970-01-01)
+is required. Negative numbers are relative to the current time. By default,
+one day worth of data will be fetched. See also AT-STYLE TIME SPECIFICATION
+section for a detailed explanation on  ways to specify the start time.
+
+=item B<--end>|B<-e> I<end> (default now)
+
+the end of the time series in seconds since epoch. See also AT-STYLE
+TIME SPECIFICATION section for a detailed explanation of how to
+specify the end time.
+
+=back
+
+=head2 RESOLUTION INTERVAL
+
+In order to get RRDtool to fetch anything other than the finest resolution RRA
+B<both> the start and end time must be specified on boundaries that are
+multiples of the desired resolution. Consider the following example:
+
+ rrdtool create subdata.rrd -s 10 DS:ds0:GAUGE:300:0:U \
+  RRA:AVERAGE:0.5:30:3600 \
+  RRA:AVERAGE:0.5:90:1200 \
+  RRA:AVERAGE:0.5:360:1200 \
+  RRA:MAX:0.5:360:1200 \
+  RRA:AVERAGE:0.5:8640:600 \
+  RRA:MAX:0.5:8640:600
+
+This RRD collects data every 10 seconds and stores its averages over 5
+minutes, 15 minutes, 1 hour, and 1 day, as well as the maxima for 1 hour
+and 1 day.
+
+Consider now that you want to fetch the 15 minute average data for the
+last hour.  You might try
+
+ rrdtool fetch subdata.rrd AVERAGE -r 900 -s -1h
+
+However, this will almost always result in a time series that is
+B<NOT> in the 15 minute RRA. Therefore, the highest resolution RRA,
+i.e. 5 minute averages, will be chosen which in this case is not
+what you want.
+
+Hence, make sure that
+
+=over 3
+
+=item 1.
+
+both start and end time are a multiple of 900
+
+=item 2.
+
+both start and end time are within the desired RRA
+
+=back
+
+So, if time now is called "t", do
+
+ end time == int(t/900)*900,
+ start time == end time - 1hour,
+ resolution == 900.
+
+Using the bash shell, this could look be:
+
+ TIME=$(date +%s)
+ RRDRES=900
+ rrdtool fetch subdata.rrd AVERAGE -r $RRDRES \
+    -e $(($TIME/$RRDRES*$RRDRES)) -s e-1h
+
+Or in Perl:
+
+ perl -e '$ctime = time; $rrdres = 900; \
+          system "rrdtool fetch subdata.rrd AVERAGE \
+                  -r $rrdres -e @{[int($ctime/$rrdres)*$rrdres]} -s e-1h"'
+
+
+=head2 AT-STYLE TIME SPECIFICATION
+
+Apart from the traditional I<Seconds since epoch>, RRDtool does also
+understand at-style time specification. The specification is called
+"at-style" after the Unix command at(1) that has moderately complex
+ways to specify time to run your job at a certain date and time. The
+at-style specification consists of two parts: the B<TIME REFERENCE>
+specification and the B<TIME OFFSET> specification.
+
+=head2 TIME REFERENCE SPECIFICATION
+
+The time reference specification is used, well, to establish a reference
+moment in time (to which the time offset is then applied to). When present,
+it should come first, when omitted, it defaults to B<now>. On its own part,
+time reference consists of a I<time-of-day> reference (which should come
+first, if present) and a I<day> reference.
+
+The I<time-of-day> can be specified as B<HH:MM>, B<HH.MM>,
+or just B<HH>. You can suffix it with B<am> or B<pm> or use
+24-hours clock. Some special times of day are understood as well,
+including B<midnight> (00:00), B<noon> (12:00) and British
+B<teatime> (16:00).
+
+The I<day> can be specified as I<month-name> I<day-of-the-month> and
+optional a 2- or 4-digit I<year> number (e.g. March 8 1999). Alternatively,
+you can use I<day-of-week-name> (e.g. Monday), or one of the words:
+B<yesterday>, B<today>, B<tomorrow>. You can also specify the I<day> as a

+
+Finally, you can use the words B<now>, B<start>, or B<end> as your time

+time reference). B<Start> (B<end>) can be used to specify a time

+categories (B<rrdfetch>, L<rrdgraph>).
+
+Month and day of the week names can be used in their naturally
+abbreviated form (e.g., Dec for December, Sun for Sunday, etc.). The
+words B<now>, B<start>, B<end> can be abbreviated as B<n>, B<s>, B<e>.
+
+=head2 TIME OFFSET SPECIFICATION
+
+The time offset specification is used to add/subtract certain time
+intervals to/from the time reference moment. It consists of a I<sign>
+(S<B<+> or B<->>) and an I<amount>. The following time units can be
+used to specify the I<amount>: B<years>, B<months>, B<weeks>, B<days>,
+B<hours>, B<minutes>, or B<seconds>. These units can be used in
+singular or plural form, and abbreviated naturally or to a single
+letter (e.g. +3days, -1wk, -3y). Several time units can be combined
+(e.g., -5mon1w2d) or concatenated (e.g., -5h45min = -5h-45min =
+-6h+15min = -7h+1h30m-15min, etc.)
+
+I<NOTE3>: If you specify time offset in days, weeks, months, or years,
+you will end with the time offset that may vary depending on your time
+reference, because all those time units have no single well defined
+time interval value (S<1 year> contains either 365 or 366 days, S<1 month>
+is 28 to 31 days long, and even S<1 day> may be not equal to 24 hours
+twice a year, when DST-related clock adjustments take place).
+To cope with this, when you use days, weeks, months, or years
+as your time offset units your time reference date is adjusted
+accordingly without too much further effort to ensure anything
+about it (in the hope that mktime(3) will take care of this later).
+This may lead to some surprising (or even invalid!) results,
+e.g. S<'May 31 -1month'> = S<'Apr 31'> (meaningless) = S<'May 1'>
+(after mktime(3) normalization); in the EET timezone
+'3:30am Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' (Sunday)
+which is an invalid time/date combination (because of 3am -> 4am DST
+forward clock adjustment, see the below example).
+
+In contrast, hours, minutes, and seconds are well defined time
+intervals, and these are guaranteed to always produce time offsets
+exactly as specified (e.g. for EET timezone, S<'8:00 Mar 27 1999 +2
+days'> = S<'8:00 Mar 29 1999'>, but since there is 1-hour DST forward
+clock adjustment that occurs around S<3:00 Mar 28 1999>, the actual
+time interval between S<8:00 Mar 27 1999> and S<8:00 Mar 29 1999>
+equals 47 hours; on the other hand, S<'8:00 Mar 27 1999 +48 hours'> =
+S<'9:00 Mar 29 1999'>, as expected)
+
+I<NOTE4>: The single-letter abbreviation for both B<months> and B<minutes>
+is B<m>. To disambiguate them, the parser tries to read your S<mind :)>
+by applying the following two heuristics:
+
+=over 3
+
+=item 1
+
+If B<m> is used in context of (i.e. right after the) years,
+months, weeks, or days it is assumed to mean B<months>, while
+in the context of hours, minutes, and seconds it means minutes.
+(e.g., in -1y6m or +3w1m B<m> is interpreted as B<months>, while in
+-3h20m or +5s2m B<m> the parser decides for B<minutes>).
+
+=item 2
+
+Out of context (i.e. right after the B<+> or B<-> sign) the
+meaning of B<m> is guessed from the number it directly follows.
+Currently, if the number's absolute value is below 25 it is assumed
+that B<m> means B<months>, otherwise it is treated as B<minutes>.
+(e.g., -25m == -25 minutes, while +24m == +24 months)
+
+=back
+

+Whitespace can be inserted freely or omitted altogether.
+There are, however, cases when whitespace is required
+(e.g., S<'midnight Thu'>). In this case you should either quote the

+       The f\bfe\bet\btc\bch\bh function is normally used internally by the graph function to
+       get data from R\bRR\bRD\bDs. f\bfe\bet\btc\bch\bh will analyze the R\bRR\bRD\bD and try to retrieve the
+       data in the resolution requested.  The data fetched is printed to std-
+       out. _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* data is often represented by the string "NaN" depending
+       on your OS's printf function.

+               the name of the R\bRR\bRD\bD you want to fetch the data from.
+
+       _\bC_\bF      the consolidation function that is applied to the data you want

+               r\brr\brd\bdf\bfe\bet\btc\bch\bh will try to match your request, but it will return

+               start of the time series. A time in seconds since epoch
+               (1970-01-01) is required. Negative numbers are relative to the
+               current time. By default, one day worth of data will be
+               fetched. See also AT-STYLE TIME SPECIFICATION section for a
+               detailed explanation on  ways to specify the start time.
+
+       -\b--\b-e\ben\bnd\bd|-\b-e\be _\be_\bn_\bd (default now)
+               the end of the time series in seconds since epoch. See also AT-
+               STYLE TIME SPECIFICATION section for a detailed explanation of
+               how to specify the end time.

+
+       In order to get RRDtool to fetch anything other than the finest resolu-
+       tion RRA b\bbo\bot\bth\bh the start and end time must be specified on boundaries
+       that are multiples of the desired resolution. Consider the following
+       example:
+
+        rrdtool create subdata.rrd -s 10 DS:ds0:GAUGE:300:0:U \
+         RRA:AVERAGE:0.5:30:3600 \
+         RRA:AVERAGE:0.5:90:1200 \
+         RRA:AVERAGE:0.5:360:1200 \
+         RRA:MAX:0.5:360:1200 \
+         RRA:AVERAGE:0.5:8640:600 \
+         RRA:MAX:0.5:8640:600
+
+       This RRD collects data every 10 seconds and stores its averages over 5
+       minutes, 15 minutes, 1 hour, and 1 day, as well as the maxima for 1
+       hour and 1 day.
+
+       Consider now that you want to fetch the 15 minute average data for the
+       last hour.  You might try
+
+        rrdtool fetch subdata.rrd AVERAGE -r 900 -s -1h
+
+       However, this will almost always result in a time series that is N\bNO\bOT\bT in
+       the 15 minute RRA. Therefore, the highest resolution RRA, i.e. 5 minute
+       averages, will be chosen which in this case is not what you want.
+
+       Hence, make sure that
+
+       1. both start and end time are a multiple of 900
+
+       2. both start and end time are within the desired RRA
+
+       So, if time now is called "t", do
+
+        end time == int(t/900)*900,
+        start time == end time - 1hour,
+        resolution == 900.
+
+       Using the bash shell, this could look be:
+
+        TIME=$(date +%s)
+        RRDRES=900
+        rrdtool fetch subdata.rrd AVERAGE -r $RRDRES \
+           -e $(($TIME/$RRDRES*$RRDRES)) -s e-1h
+
+       Or in Perl:
+
+        perl -e '$ctime = time; $rrdres = 900; \
+                 system "rrdtool fetch subdata.rrd AVERAGE \
+                         -r $rrdres -e @{[int($ctime/$rrdres)*$rrdres]} -s e-1h"'
+
+       A\bAT\bT-\b-S\bST\bTY\bYL\bLE\bE T\bTI\bIM\bME\bE S\bSP\bPE\bEC\bCI\bIF\bFI\bIC\bCA\bAT\bTI\bIO\bON\bN
+
+       Apart from the traditional _\bS_\be_\bc_\bo_\bn_\bd_\bs _\bs_\bi_\bn_\bc_\be _\be_\bp_\bo_\bc_\bh, RRDtool does also
+       understand at-style time specification. The specification is called
+       "at-style" after the Unix command _\ba_\bt(1) that has moderately complex
+       ways to specify time to run your job at a certain date and time. The
+       at-style specification consists of two parts: the T\bTI\bIM\bME\bE R\bRE\bEF\bFE\bER\bRE\bEN\bNC\bCE\bE speci-
+       fication and the T\bTI\bIM\bME\bE O\bOF\bFF\bFS\bSE\bET\bT specification.
+
+       T\bTI\bIM\bME\bE R\bRE\bEF\bFE\bER\bRE\bEN\bNC\bCE\bE S\bSP\bPE\bEC\bCI\bIF\bFI\bIC\bCA\bAT\bTI\bIO\bON\bN
+
+       The time reference specification is used, well, to establish a refer-
+       ence moment in time (to which the time offset is then applied to). When
+       present, it should come first, when omitted, it defaults to n\bno\bow\bw. On its
+       own part, time reference consists of a _\bt_\bi_\bm_\be_\b-_\bo_\bf_\b-_\bd_\ba_\by reference (which
+       should come first, if present) and a _\bd_\ba_\by reference.
+
+       The _\bt_\bi_\bm_\be_\b-_\bo_\bf_\b-_\bd_\ba_\by can be specified as H\bHH\bH:\b:M\bMM\bM, H\bHH\bH.\b.M\bMM\bM, or just H\bHH\bH. You can
+       suffix it with a\bam\bm or p\bpm\bm or use 24-hours clock. Some special times of
+       day are understood as well, including m\bmi\bid\bdn\bni\big\bgh\bht\bt (00:00), n\bno\boo\bon\bn (12:00)
+       and British t\bte\bea\bat\bti\bim\bme\be (16:00).
+
+       The _\bd_\ba_\by can be specified as _\bm_\bo_\bn_\bt_\bh_\b-_\bn_\ba_\bm_\be _\bd_\ba_\by_\b-_\bo_\bf_\b-_\bt_\bh_\be_\b-_\bm_\bo_\bn_\bt_\bh and optional a
+       2- or 4-digit _\by_\be_\ba_\br number (e.g. March 8 1999). Alternatively, you can
+       use _\bd_\ba_\by_\b-_\bo_\bf_\b-_\bw_\be_\be_\bk_\b-_\bn_\ba_\bm_\be (e.g. Monday), or one of the words: y\bye\bes\bst\bte\ber\brd\bda\bay\by,
+       t\bto\bod\bda\bay\by, t\bto\bom\bmo\bor\brr\bro\bow\bw. You can also specify the _\bd_\ba_\by as a full date in several
+       numerical formats, including M\bMM\bM/\b/D\bDD\bD/\b/[\b[Y\bYY\bY]\b]Y\bYY\bY, D\bDD\bD.\b.M\bMM\bM.\b.[\b[Y\bYY\bY]\b]Y\bYY\bY, or Y\bYY\bYY\bYY\bYM\bMM\bMD\bDD\bD.
+
+       _\bN_\bO_\bT_\bE_\b1: this is different from the original _\ba_\bt(1) behavior, where a sin-
+       gle-number date is interpreted as MMDD[YY]YY.
+
+       _\bN_\bO_\bT_\bE_\b2: if you specify the _\bd_\ba_\by in this way, the _\bt_\bi_\bm_\be_\b-_\bo_\bf_\b-_\bd_\ba_\by is REQUIRED
+       as well.
+
+       Finally, you can use the words n\bno\bow\bw, s\bst\bta\bar\brt\bt, or e\ben\bnd\bd as your time refer-
+       ence. N\bNo\bow\bw refers to the current moment (and is also the default time
+       reference). S\bSt\bta\bar\brt\bt (e\ben\bnd\bd) can be used to specify a time relative to the
+       start (end) time for those tools that use these categories (r\brr\brd\bdf\bfe\bet\btc\bch\bh,
+       rrdgraph).
+
+       Month and day of the week names can be used in their naturally abbrevi-
+       ated form (e.g., Dec for December, Sun for Sunday, etc.). The words
+       n\bno\bow\bw, s\bst\bta\bar\brt\bt, e\ben\bnd\bd can be abbreviated as n\bn, s\bs, e\be.
+
+       T\bTI\bIM\bME\bE O\bOF\bFF\bFS\bSE\bET\bT S\bSP\bPE\bEC\bCI\bIF\bFI\bIC\bCA\bAT\bTI\bIO\bON\bN
+
+       The time offset specification is used to add/subtract certain time
+       intervals to/from the time reference moment. It consists of a _\bs_\bi_\bg_\bn
+       (+\b+ or -\b-) and an _\ba_\bm_\bo_\bu_\bn_\bt. The following time units can be used to specify
+       the _\ba_\bm_\bo_\bu_\bn_\bt: y\bye\bea\bar\brs\bs, m\bmo\bon\bnt\bth\bhs\bs, w\bwe\bee\bek\bks\bs, d\bda\bay\bys\bs, h\bho\bou\bur\brs\bs, m\bmi\bin\bnu\but\bte\bes\bs, or s\bse\bec\bco\bon\bnd\bds\bs.
+       These units can be used in singular or plural form, and abbreviated
+       naturally or to a single letter (e.g. +3days, -1wk, -3y). Several time
+       units can be combined (e.g., -5mon1w2d) or concatenated (e.g., -5h45min
+       = -5h-45min = -6h+15min = -7h+1h30m-15min, etc.)
+
+       _\bN_\bO_\bT_\bE_\b3: If you specify time offset in days, weeks, months, or years, you
+       will end with the time offset that may vary depending on your time ref-
+       erence, because all those time units have no single well defined time
+       interval value (1 year contains either 365 or 366 days, 1 month is 28
+       to 31 days long, and even 1 day may be not equal to 24 hours twice a
+       year, when DST-related clock adjustments take place).  To cope with
+       this, when you use days, weeks, months, or years as your time offset
+       units your time reference date is adjusted accordingly without too much
+       further effort to ensure anything about it (in the hope that _\bm_\bk_\bt_\bi_\bm_\be(3)
+       will take care of this later).  This may lead to some surprising (or
+       even invalid!) results, e.g. 'May 31 -1month' = 'Apr 31' (meaningless)
+       = 'May 1' (after _\bm_\bk_\bt_\bi_\bm_\be(3) normalization); in the EET timezone '3:30am
+       Mar 29 1999 -1 day' yields '3:30am Mar 28 1999' (Sunday) which is an
+       invalid time/date combination (because of 3am -> 4am DST forward clock
+       adjustment, see the below example).
+
+       In contrast, hours, minutes, and seconds are well defined time inter-
+       vals, and these are guaranteed to always produce time offsets exactly
+       as specified (e.g. for EET timezone, '8:00 Mar 27 1999 +2 days' =
+       '8:00 Mar 29 1999', but since there is 1-hour DST forward clock adjust-
+       ment that occurs around 3:00 Mar 28 1999, the actual time interval
+       between 8:00 Mar 27 1999 and 8:00 Mar 29 1999 equals 47 hours; on the
+       other hand, '8:00 Mar 27 1999 +48 hours' = '9:00 Mar 29 1999', as
+       expected)
+
+       _\bN_\bO_\bT_\bE_\b4: The single-letter abbreviation for both m\bmo\bon\bnt\bth\bhs\bs and m\bmi\bin\bnu\but\bte\bes\bs is m\bm.
+       To disambiguate them, the parser tries to read your mind :) by applying
+       the following two heuristics:
+
+       1  If m\bm is used in context of (i.e. right after the) years, months,
+          weeks, or days it is assumed to mean m\bmo\bon\bnt\bth\bhs\bs, while in the context of
+          hours, minutes, and seconds it means minutes.  (e.g., in -1y6m or
+          +3w1m m\bm is interpreted as m\bmo\bon\bnt\bth\bhs\bs, while in -3h20m or +5s2m m\bm the
+          parser decides for m\bmi\bin\bnu\but\bte\bes\bs).
+
+       2  Out of context (i.e. right after the +\b+ or -\b- sign) the meaning of m\bm
+          is guessed from the number it directly follows.  Currently, if the
+          number's absolute value is below 25 it is assumed that m\bm means
+          m\bmo\bon\bnt\bth\bhs\bs, otherwise it is treated as m\bmi\bin\bnu\but\bte\bes\bs.  (e.g., -25m == -25 min-
+          utes, while +24m == +24 months)
+
+       _\bF_\bi_\bn_\ba_\bl _\bN_\bO_\bT_\bE_\bS: Time specification is case-insensitive.  Whitespace can be
+       inserted freely or omitted altogether.  There are, however, cases when
+       whitespace is required (e.g., 'midnight Thu'). In this case you should
+       either quote the whole phrase to prevent it from being taken apart by
+       your shell or use '_' (underscore) or ',' (comma) which also count as
+       whitespace (e.g., midnight_Thu or midnight,Thu).

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBgraph\fR function of \fBRRDtool\fR is used to present the
+data from an \fB\s-1RRD\s0\fR to a human viewer.  Its main purpose is to
+create a nice graphical representation, but it can also generate
+a numerical report.
+.SH "OVERVIEW"
+.IX Header "OVERVIEW"
+\&\fBrrdtool graph\fR needs data to work with, so you must use one or more
+\&\fBdata definition\fR statements to collect this
+data.  You are not limited to one database, it's perfectly legal to
+collect data from two or more databases (one per statement, though).
+.PP
+If you want to display averages, maxima, percentiles, etcetera
+it is best to collect them now using the
+\&\fBvariable definition\fR statement.
+Currently this makes no difference, but in a future version
+of rrdtool you may want to collect these values before consolidation.
+.PP
+The data fetched from the \fB\s-1RRA\s0\fR is then \fBconsolidated\fR so that
+there is exactly one datapoint per pixel in the graph. If you do
+not take care yourself, \fBRRDtool\fR will expand the range slightly
+if necessary. Note, in that case the first and/or last pixel may very
+well become unknown!
+.PP
+Sometimes data is not exactly in the format you would like to display
+it. For instance, you might be collecting \fBbytes\fR per second, but
+want to display \fBbits\fR per second. This is what the \fBdata calculation\fR command is designed for. After
+\&\fBconsolidating\fR the data, a copy is made and this copy is modified
+using a rather powerful \fB\s-1RPN\s0\fR command set.
+.PP
+When you are done fetching and processing the data, it is time to
+graph it (or print it).  This ends the \fBrrdtool graph\fR sequence.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "filename" 4
+.IX Item "filename"
+The name and path of the graph to generate. It is recommended to
+end this in \f(CW\*(C`.png\*(C'\fR, \f(CW\*(C`.svg\*(C'\fR or \f(CW\*(C`.eps\*(C'\fR, but \fBRRDtool\fR does not enforce this.
+.Sp
+\&\fIfilename\fR can be '\f(CW\*(C`\-\*(C'\fR' to send the image to \f(CW\*(C`stdout\*(C'\fR. In
+this case, no other output is generated.
+.IP "Time range" 4
+.IX Item "Time range"
+[\fB\-s\fR|\fB\-\-start\fR \fItime\fR]
+[\fB\-e\fR|\fB\-\-end\fR \fItime\fR]
+[\fB\-S\fR|\fB\-\-step\fR \fIseconds\fR]
+.Sp
+The start and end of the time series you would like to display, and which
+\&\fB\s-1RRA\s0\fR the data should come from.  Defaults are: 1 day ago until
+now, with the best possible resolution. \fBStart\fR and \fBend\fR can
+be specified in several formats, see
+AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0 and rrdgraph_examples.
+By default, \fBrrdtool graph\fR calculates the width of one pixel in
+the time domain and tries to get data from an \fB\s-1RRA\s0\fR with that
+resolution.  With the \fBstep\fR option you can alter this behaviour.
+If you want \fBrrdtool graph\fR to get data at a one-hour resolution
+from the \fB\s-1RRD\s0\fR, set \fBstep\fR to 3'600. Note: a step smaller than
+one pixel will silently be ignored.
+.IP "Labels" 4
+.IX Item "Labels"
+[\fB\-t\fR|\fB\-\-title\fR \fIstring\fR]
+[\fB\-v\fR|\fB\-\-vertical\-label\fR \fIstring\fR]
+.Sp
+A horizontal string at the top of the graph and/or a vertically
+placed string at the left hand side of the graph.
+.IP "Size" 4
+.IX Item "Size"
+[\fB\-w\fR|\fB\-\-width\fR \fIpixels\fR]
+[\fB\-h\fR|\fB\-\-height\fR \fIpixels\fR]
+[\fB\-j\fR|\fB\-\-only\-graph\fR]
+.Sp
+The width and height of the \fBcanvas\fR (the part of the graph with
+the actual data and such). This defaults to 400 pixels by 100 pixels.
+.Sp
+If you specify the \fB\-\-only\-graph\fR option and set the height < 32
+pixels you will get a tiny graph image (thumbnail) to use as an icon
+for use in an overview, for example. All labeling will be stripped off
+the graph.
+.IP "Limits" 4
+.IX Item "Limits"
+[\fB\-u\fR|\fB\-\-upper\-limit\fR \fIvalue\fR]
+[\fB\-l\fR|\fB\-\-lower\-limit\fR \fIvalue\fR]
+[\fB\-r\fR|\fB\-\-rigid\fR]
+.Sp
+By default the graph will be autoscaling so that it will adjust the
+y\-axis to the range of the data. You can change this behaviour by
+explicitly setting the limits. The displayed y\-axis will then range at
+least from \fBlower-limit\fR to \fBupper-limit\fR. Autoscaling will still
+permit those boundaries to be stretched unless the \fBrigid\fR option is
+set.
+.Sp
+[\fB\-A\fR|\fB\-\-alt\-autoscale\fR]
+.Sp
+Sometimes the default algorithm for selecting the y\-axis scale is not
+satisfactory. Normally the scale is selected from a predefined
+set of ranges and this fails miserably when you need to graph something
+like \f(CW\*(C`260 + 0.001 * sin(x)\*(C'\fR. This option calculates the minimum and
+maximum y\-axis from the actual minimum and maximum data values. Our example
+would display slightly less than \f(CW\*(C`260\-0.001\*(C'\fR to slightly more than
+\&\f(CW\*(C`260+0.001\*(C'\fR (this feature was contributed by Sasha Mikheev).
+.Sp
+[\fB\-J\fR|\fB\-\-alt\-autoscale\-min\fR]
+.Sp
+Where \f(CW\*(C`\-\-alt\-autoscale\*(C'\fR will modify both the absolute maximum \s-1AND\s0 minimum
+values, this option will only affect the minimum value. The maximum
+value, if not defined on the command line, will be 0. This option can
+be useful when graphing router traffic when the \s-1WAN\s0 line uses compression,
+and thus the throughput may be higher than the \s-1WAN\s0 line speed.
+.Sp
+[\fB\-M\fR|\fB\-\-alt\-autoscale\-max\fR]
+.Sp
+Where \f(CW\*(C`\-\-alt\-autoscale\*(C'\fR will modify both the absolute maximum \s-1AND\s0 minimum
+values, this option will only affect the maximum value. The minimum
+value, if not defined on the command line, will be 0. This option can
+be useful when graphing router traffic when the \s-1WAN\s0 line uses compression,
+and thus the throughput may be higher than the \s-1WAN\s0 line speed.
+.Sp
+[\fB\-N\fR|\fB\-\-no\-gridfit\fR]
+.Sp
+In order to avoid anti-aliasing effects gridlines are placed on
+integer pixel values. This is by default done by extending
+the scale so that gridlines happens to be spaced using an
+integer number of pixels and also start on an integer pixel value.
+This might extend the scale too much for some logarithmic scales
+and for linear scales where \fB\-\-alt\-autoscale\fR is needed.
+Using \fB\-\-no\-gridfit\fR disables modification of the scale.

+.Sp
+The x\-axis label is quite complex to configure. If you don't have
+very special needs it is probably best to rely on the autoconfiguration
+to get this right. You can specify the string \f(CW\*(C`none\*(C'\fR to suppress the grid
+and labels altogether.
+.Sp
+The grid is defined by specifying a certain amount of time in the \fI?TM\fR
+positions. You can choose from \f(CW\*(C`SECOND\*(C'\fR, \f(CW\*(C`MINUTE\*(C'\fR, \f(CW\*(C`HOUR\*(C'\fR, \f(CW\*(C`DAY\*(C'\fR,
+\&\f(CW\*(C`WEEK\*(C'\fR, \f(CW\*(C`MONTH\*(C'\fR or \f(CW\*(C`YEAR\*(C'\fR. Then you define how many of these should
+pass between each line or label.  This pair (\fI?TM:?ST\fR) needs to be
+specified for the base grid (\fIG??\fR), the major grid (\fIM??\fR) and the

+you may wish to display units always in k (Kilo, 10e3) even if the data
+is in the M (Mega, 10e6) range, for instance. Value should be an
+integer which is a multiple of 3 between \-18 and 18 inclusively.  It is
+the exponent on the units you wish to use. For example, use 3 to
+display the y\-axis values in k (Kilo, 10e3, thousands), use \-6 to
+display the y\-axis values in u (Micro, 10e\-6, millionths).  Use a value
+of 0 to prevent any scaling of the y\-axis values.
+.Sp
+This option is very effective at confusing the heck out of the default

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>The <strong>graph</strong> function of <strong>RRDtool</strong> is used to present the
+data from an <strong>RRD</strong> to a human viewer.  Its main purpose is to
+create a nice graphical representation, but it can also generate
+a numerical report.</p>
+<p>
+</p>
+<hr />
+<h1><a name="overview">OVERVIEW</a></h1>
+<p><strong>rrdtool graph</strong> needs data to work with, so you must use one or more
+<strong><a href="././rrdgraph_data.html#def">data definition</a></strong> statements to collect this
+data.  You are not limited to one database, it's perfectly legal to
+collect data from two or more databases (one per statement, though).</p>
+<p>If you want to display averages, maxima, percentiles, etcetera
+it is best to collect them now using the
+<strong><a href="././rrdgraph_data.html#vdef">variable definition</a></strong> statement.
+Currently this makes no difference, but in a future version
+of rrdtool you may want to collect these values before consolidation.</p>
+<p>The data fetched from the <strong>RRA</strong> is then <strong>consolidated</strong> so that
+there is exactly one datapoint per pixel in the graph. If you do
+not take care yourself, <strong>RRDtool</strong> will expand the range slightly
+if necessary. Note, in that case the first and/or last pixel may very
+well become unknown!</p>
+<p>Sometimes data is not exactly in the format you would like to display
+it. For instance, you might be collecting <strong>bytes</strong> per second, but
+want to display <strong>bits</strong> per second. This is what the <strong><a href="././rrdgraph_data.html#cdef">data calculation</a></strong> command is designed for. After
+<strong>consolidating</strong> the data, a copy is made and this copy is modified
+using a rather powerful <strong><a href="././rrdgraph_rpn.html">RPN</a></strong> command set.</p>
+<p>When you are done fetching and processing the data, it is time to
+graph it (or print it).  This ends the <strong>rrdtool graph</strong> sequence.</p>

+be specified in several formats, see
+<a href="././rrdfetch.html">AT-STYLE TIME SPECIFICATION</a> and <a href="././rrdgraph_examples.html">the rrdgraph_examples manpage</a>.
+By default, <strong>rrdtool graph</strong> calculates the width of one pixel in
+the time domain and tries to get data from an <strong>RRA</strong> with that
+resolution.  With the <strong>step</strong> option you can alter this behaviour.
+If you want <strong>rrdtool graph</strong> to get data at a one-hour resolution
+from the <strong>RRD</strong>, set <strong>step</strong> to 3'600. Note: a step smaller than
+one pixel will silently be ignored.</p>

+<p>By default the graph will be autoscaling so that it will adjust the

+like <code>260 + 0.001 * sin(x)</code>. This option calculates the minimum and
+maximum y-axis from the actual minimum and maximum data values. Our example

+=head1 NAME
+
+rrdgraph - Round Robin Database tool grapher functions
+
+=head1 SYNOPSIS
+
+B<rrdtool graph> I<filename>
+[I<L<option|rrdgraph/OPTIONS>> ...]
+[I<L<data definition|rrdgraph_data/DEF>> ...]
+[I<L<data calculation|rrdgraph_data/CDEF>> ...]
+[I<L<variable definition|rrdgraph_data/VDEF>> ...]
+[I<L<graph element|rrdgraph_graph/GRAPH>> ...]
+[I<L<print element|rrdgraph_graph/PRINT>> ...]
+
+=head1 DESCRIPTION
+
+The B<graph> function of B<RRDtool> is used to present the
+data from an B<RRD> to a human viewer.  Its main purpose is to
+create a nice graphical representation, but it can also generate
+a numerical report.
+
+=head1 OVERVIEW
+
+B<rrdtool graph> needs data to work with, so you must use one or more
+B<L<data definition|rrdgraph_data/DEF>> statements to collect this
+data.  You are not limited to one database, it's perfectly legal to
+collect data from two or more databases (one per statement, though).
+
+If you want to display averages, maxima, percentiles, etcetera
+it is best to collect them now using the
+B<L<variable definition|rrdgraph_data/VDEF>> statement.
+Currently this makes no difference, but in a future version
+of rrdtool you may want to collect these values before consolidation.
+
+The data fetched from the B<RRA> is then B<consolidated> so that
+there is exactly one datapoint per pixel in the graph. If you do
+not take care yourself, B<RRDtool> will expand the range slightly
+if necessary. Note, in that case the first and/or last pixel may very
+well become unknown!
+
+Sometimes data is not exactly in the format you would like to display
+it. For instance, you might be collecting B<bytes> per second, but
+want to display B<bits> per second. This is what the B<L<data
+calculation|rrdgraph_data/CDEF>> command is designed for. After
+B<consolidating> the data, a copy is made and this copy is modified
+using a rather powerful B<L<RPN|rrdgraph_rpn/>> command set.
+
+When you are done fetching and processing the data, it is time to
+graph it (or print it).  This ends the B<rrdtool graph> sequence.
+
+=head1 OPTIONS
+
+=over 4
+
+=item filename
+
+The name and path of the graph to generate. It is recommended to
+end this in C<.png>, C<.svg> or C<.eps>, but B<RRDtool> does not enforce this.
+
+I<filename> can be 'C<->' to send the image to C<stdout>. In
+this case, no other output is generated.
+
+=item Time range
+
+[B<-s>|B<--start> I<time>]
+[B<-e>|B<--end> I<time>]
+[B<-S>|B<--step> I<seconds>]
+
+The start and end of the time series you would like to display, and which
+B<RRA> the data should come from.  Defaults are: 1 day ago until
+now, with the best possible resolution. B<Start> and B<end> can
+be specified in several formats, see
+L<AT-STYLE TIME SPECIFICATION|rrdfetch/> and L<rrdgraph_examples>.
+By default, B<rrdtool graph> calculates the width of one pixel in
+the time domain and tries to get data from an B<RRA> with that
+resolution.  With the B<step> option you can alter this behaviour.
+If you want B<rrdtool graph> to get data at a one-hour resolution
+from the B<RRD>, set B<step> to 3'600. Note: a step smaller than
+one pixel will silently be ignored.
+
+=item Labels
+
+[B<-t>|B<--title> I<string>]
+[B<-v>|B<--vertical-label> I<string>]
+
+A horizontal string at the top of the graph and/or a vertically
+placed string at the left hand side of the graph.
+
+=item Size
+
+[B<-w>|B<--width> I<pixels>]
+[B<-h>|B<--height> I<pixels>]
+[B<-j>|B<--only-graph>]
+
+The width and height of the B<canvas> (the part of the graph with
+the actual data and such). This defaults to 400 pixels by 100 pixels.
+
+If you specify the B<--only-graph> option and set the height E<lt> 32
+pixels you will get a tiny graph image (thumbnail) to use as an icon
+for use in an overview, for example. All labeling will be stripped off
+the graph.
+
+=item Limits
+
+[B<-u>|B<--upper-limit> I<value>]
+[B<-l>|B<--lower-limit> I<value>]
+[B<-r>|B<--rigid>]
+
+By default the graph will be autoscaling so that it will adjust the
+y-axis to the range of the data. You can change this behaviour by
+explicitly setting the limits. The displayed y-axis will then range at
+least from B<lower-limit> to B<upper-limit>. Autoscaling will still
+permit those boundaries to be stretched unless the B<rigid> option is
+set.
+
+[B<-A>|B<--alt-autoscale>]
+
+Sometimes the default algorithm for selecting the y-axis scale is not
+satisfactory. Normally the scale is selected from a predefined
+set of ranges and this fails miserably when you need to graph something
+like C<260 + 0.001 * sin(x)>. This option calculates the minimum and
+maximum y-axis from the actual minimum and maximum data values. Our example
+would display slightly less than C<260-0.001> to slightly more than
+C<260+0.001> (this feature was contributed by Sasha Mikheev).
+
+[B<-J>|B<--alt-autoscale-min>]
+
+Where C<--alt-autoscale> will modify both the absolute maximum AND minimum
+values, this option will only affect the minimum value. The maximum
+value, if not defined on the command line, will be 0. This option can
+be useful when graphing router traffic when the WAN line uses compression,
+and thus the throughput may be higher than the WAN line speed.
+
+[B<-M>|B<--alt-autoscale-max>]
+
+Where C<--alt-autoscale> will modify both the absolute maximum AND minimum
+values, this option will only affect the maximum value. The minimum
+value, if not defined on the command line, will be 0. This option can
+be useful when graphing router traffic when the WAN line uses compression,
+and thus the throughput may be higher than the WAN line speed.
+
+[B<-N>|B<--no-gridfit>]
+
+In order to avoid anti-aliasing effects gridlines are placed on
+integer pixel values. This is by default done by extending
+the scale so that gridlines happens to be spaced using an
+integer number of pixels and also start on an integer pixel value.
+This might extend the scale too much for some logarithmic scales
+and for linear scales where B<--alt-autoscale> is needed.
+Using B<--no-gridfit> disables modification of the scale.
+
+=item Grid
+
+=over 4
+
+=item X-Axis
+
+[B<-x>|B<--x-grid> I<GTM>B<:>I<GST>B<:>I<MTM>B<:>I<MST>B<:>I<LTM>B<:>I<LST>B<:>I<LPR>B<:>I<LFM>]
+
+[B<-x>|B<--x-grid> B<none>]
+
+The x-axis label is quite complex to configure. If you don't have
+very special needs it is probably best to rely on the autoconfiguration
+to get this right. You can specify the string C<none> to suppress the grid
+and labels altogether.
+
+The grid is defined by specifying a certain amount of time in the I<?TM>
+positions. You can choose from C<SECOND>, C<MINUTE>, C<HOUR>, C<DAY>,
+C<WEEK>, C<MONTH> or C<YEAR>. Then you define how many of these should
+pass between each line or label.  This pair (I<?TM:?ST>) needs to be
+specified for the base grid (I<G??>), the major grid (I<M??>) and the
+labels (I<L??>). For the labels you also must define a precision
+in I<LPR> and a I<strftime> format string in I<LFM>.  I<LPR> defines
+where each label will be placed. If it is zero, the label will be
+placed right under the corresponding line (useful for hours, dates
+etcetera).  If you specify a number of seconds here the label is
+centered on this interval (useful for Monday, January etcetera).
+
+ --x-grid MINUTE:10:HOUR:1:HOUR:4:0:%X
+
+This places grid lines every 10 minutes, major grid lines every hour,
+and labels every 4 hours. The labels are placed under the major grid
+lines as they specify exactly that time.
+
+ --x-grid HOUR:8:DAY:1:DAY:1:0:%A
+
+This places grid lines every 8 hours, major grid lines and labels
+each day. The labels are placed exactly between two major grid lines
+as they specify the complete day and not just midnight.
+
+=item Y-Axis
+
+[B<-y>|B<--y-grid> I<grid step>B<:>I<label factor>]
+
+[B<-y>|B<--y-grid> B<none>]
+
+Y-axis grid lines appear at each I<grid step> interval.  Labels are
+placed every I<label factor> lines.  You can specify C<-y none> to
+suppress the grid and labels altogether.  The default for this option is
+to automatically select sensible values.
+
+If you have set --y-grid to 'none' not only the labels get supressed, also
+the space reserved for the labels is removed. You can still add space
+manually if you use the --units-length command to explicitly reserve space.
+
+[B<-Y>|B<--alt-y-grid>]
+
+Place the Y grid dynamically based on the graph's Y range. The algorithm
+ensures that you always have a grid, that there are enough but not too many
+grid lines, and that the grid is metric. That is the grid lines are placed
+every 1, 2, 5 or 10 units. This parameter will also ensure that you get
+enough decimals displayed even if your graph goes from 69.998 to 70.001. 
+(contributed by Sasha Mikheev).
+
+[B<-o>|B<--logarithmic>]
+
+Logarithmic y-axis scaling.
+
+[B<-X>|B<--units-exponent> I<value>]
+
+This sets the 10**exponent scaling of the y-axis values. Normally,
+values will be scaled to the appropriate units (k, M, etc.).  However,
+you may wish to display units always in k (Kilo, 10e3) even if the data
+is in the M (Mega, 10e6) range, for instance. Value should be an
+integer which is a multiple of 3 between -18 and 18 inclusively.  It is
+the exponent on the units you wish to use. For example, use 3 to
+display the y-axis values in k (Kilo, 10e3, thousands), use -6 to
+display the y-axis values in u (Micro, 10e-6, millionths).  Use a value
+of 0 to prevent any scaling of the y-axis values.
+
+This option is very effective at confusing the heck out of the default
+rrdtool autoscaler and grid painter. If rrdtool detects that it is not
+successful in labeling the graph under the given circumstances, it will switch
+to the more robust B<--alt-y-grid> mode.
+
+[B<-L>|B<--units-length> I<value>]
+
+How many digits should rrdtool assume the y-axis labels to be? You
+may have to use this option to make enough space once you start
+fideling with the y-axis labeling.
+
+[B<--units=si>]
+
+With this option y-axis values on logarithmic graphs will be scaled to 
+the appropriate units (k, M, etc.) instead of using exponential notation.
+Note that for linear graphs, SI notation is used by default.
+
+=back
+
+=item Miscellaneous
+
+[B<-z>|B<--lazy>]
+
+Only generate the graph if the current graph is out of date or not
+existent.
+
+[B<-f>|B<--imginfo> I<printfstr>]
+
+After the image has been created, the graph function uses printf
+together with this format string to create output similar to the PRINT
+function, only that the printf function is supplied with the parameters
+I<filename>, I<xsize> and I<ysize>. In order to generate an B<IMG> tag
+suitable for including the graph into a web page, the command line
+would look like this:
+
+ --imginfo '<IMG SRC="/img/%s" WIDTH="%lu" HEIGHT="%lu" ALT="Demo">'
+
+[B<-c>|B<--color> I<COLORTAG>#I<rrggbb>[I<aa>]]
+
+Override the default colors for the standard elements of the graph. The
+I<COLORTAG> is one of C<BACK> background, C<CANVAS> for the background of
+the actual graph, C<SHADEA> for the left and top border, C<SHADEB> for the
+right and bottom border, C<GRID>, C<MGRID> for the major grid, C<FONT> for
+the color of the font, C<AXIS> for the axis of the graph, C<FRAME> for the
+line around the color spots and finally C<ARROW> for the arrow head pointing
+up and forward. Each color is composed out of three hexadecimal numbers
+specifying its rgb color component (00 is off, FF is maximum) of red, green
+and blue. Optionally you may add another hexadecimal number specifying the
+transparency (FF is solid). You may set this option several times to alter
+multiple defaults.
+
+A green arrow is made by: C<--color ARROW#00FF00>
+
+[B<--zoom> I<factor>]
+
+Zoom the graphics by the given amount. The factor must be E<gt> 0
+
+[B<-n>|B<--font> I<FONTTAG>B<:>I<size>B<:>[I<font>]]
+
+This lets you customize which font to use for the various text
+elements on the RRD graphs. C<DEFAULT> sets the default value for all
+elements, C<TITLE> for the title, C<AXIS> for the axis labels, C<UNIT>
+for the vertical unit label, C<LEGEND> for the graph legend.
+
+Use Times for the title: C<--font TITLE:13:/usr/lib/fonts/times.ttf>
+
+If you do not give a font string you can modify just the sice of the default font:
+C<--font TITLE:13:>.
+
+If you specify the size 0 then you can modify just the font without touching
+the size. This is especially usefull for altering the default font without
+resetting the default fontsizes: C<--font DEFAULT:0:/usr/lib/fonts/times.ttf>.
+
+RRDtool comes with a preset default font. You can set the environment
+variable C<RRD_DEFAULT_FONT> if you want to change this.
+
+Truetype fonts are only supported for PNG output. See below.
+
+[B<-R>|B<--font-render-mode> {I<normal>,I<light>,I<mono>}]
+
+This lets you customize the strength of the font smoothing,
+or disable it entirely using I<mono>. By default, I<normal>
+font smoothing is used.
+
+[B<-B>|B<--font-smoothing-threshold> I<size>]
+
+This specifies the largest font size which will be rendered
+bitmapped, that is, without any font smoothing. By default,
+no text is rendered bitmapped.
+
+[B<-E>|B<--slope-mode>]
+
+RRDtool graphs are composed of stair case curves by default. This is in line with
+the way RRDtool calculates its data. Some people favor a more 'organic' look
+for their graphs even though it is not all that true.
+
+[B<-a>|B<--imgformat> B<PNG>|B<SVG>|B<EPS>|B<PDF>]

+       The g\bgr\bra\bap\bph\bh function of R\bRR\bRD\bDt\bto\boo\bol\bl is used to present the data from an R\bRR\bRD\bD
+       to a human viewer.  Its main purpose is to create a nice graphical rep-
+       resentation, but it can also generate a numerical report.
+

+       r\brr\brd\bdt\bto\boo\bol\bl g\bgr\bra\bap\bph\bh needs data to work with, so you must use one or more d\bda\bat\bta\ba
+       d\bde\bef\bfi\bin\bni\bit\bti\bio\bon\bn statements to collect this data.  You are not limited to one
+       database, it's perfectly legal to collect data from two or more
+       databases (one per statement, though).
+
+       If you want to display averages, maxima, percentiles, etcetera it is
+       best to collect them now using the v\bva\bar\bri\bia\bab\bbl\ble\be d\bde\bef\bfi\bin\bni\bit\bti\bio\bon\bn statement.  Cur-
+       rently this makes no difference, but in a future version of rrdtool you
+       may want to collect these values before consolidation.
+
+       The data fetched from the R\bRR\bRA\bA is then c\bco\bon\bns\bso\bol\bli\bid\bda\bat\bte\bed\bd so that there is
+       exactly one datapoint per pixel in the graph. If you do not take care
+       yourself, R\bRR\bRD\bDt\bto\boo\bol\bl will expand the range slightly if necessary. Note, in
+       that case the first and/or last pixel may very well become unknown!
+
+       Sometimes data is not exactly in the format you would like to display
+       it. For instance, you might be collecting b\bby\byt\bte\bes\bs per second, but want to
+       display b\bbi\bit\bts\bs per second. This is what the d\bda\bat\bta\ba c\bca\bal\blc\bcu\bul\bla\bat\bti\bio\bon\bn command is
+       designed for. After c\bco\bon\bns\bso\bol\bli\bid\bda\bat\bti\bin\bng\bg the data, a copy is made and this
+       copy is modified using a rather powerful R\bRP\bPN\bN command set.
+
+       When you are done fetching and processing the data, it is time to graph
+       it (or print it).  This ends the r\brr\brd\bdt\bto\boo\bol\bl g\bgr\bra\bap\bph\bh sequence.
+
+O\bOP\bPT\bTI\bIO\bON\bNS\bS
+       filename
+           The name and path of the graph to generate. It is recommended to
+           end this in ".png", ".svg" or ".eps", but R\bRR\bRD\bDt\bto\boo\bol\bl does not enforce
+           this.
+
+           _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be can be '"-"' to send the image to "stdout". In this case,
+           no other output is generated.

+
+           The start and end of the time series you would like to display, and
+           which R\bRR\bRA\bA the data should come from.  Defaults are: 1 day ago until
+           now, with the best possible resolution. S\bSt\bta\bar\brt\bt and e\ben\bnd\bd can be speci-
+           fied in several formats, see AT-STYLE TIME SPECIFICATION and rrd-
+           graph_examples.  By default, r\brr\brd\bdt\bto\boo\bol\bl g\bgr\bra\bap\bph\bh calculates the width of
+           one pixel in the time domain and tries to get data from an R\bRR\bRA\bA with
+           that resolution.  With the s\bst\bte\bep\bp option you can alter this
+           behaviour.  If you want r\brr\brd\bdt\bto\boo\bol\bl g\bgr\bra\bap\bph\bh to get data at a one-hour
+           resolution from the R\bRR\bRD\bD, set s\bst\bte\bep\bp to 3'600. Note: a step smaller
+           than one pixel will silently be ignored.

+
+           The width and height of the c\bca\ban\bnv\bva\bas\bs (the part of the graph with the
+           actual data and such). This defaults to 400 pixels by 100 pixels.
+
+           If you specify the -\b--\b-o\bon\bnl\bly\by-\b-g\bgr\bra\bap\bph\bh option and set the height < 32 pix-
+           els you will get a tiny graph image (thumbnail) to use as an icon
+           for use in an overview, for example. All labeling will be stripped
+           off the graph.
+
+       Limits
+           [-\b-u\bu|-\b--\b-u\bup\bpp\bpe\ber\br-\b-l\bli\bim\bmi\bit\bt _\bv_\ba_\bl_\bu_\be] [-\b-l\bl|-\b--\b-l\blo\bow\bwe\ber\br-\b-l\bli\bim\bmi\bit\bt _\bv_\ba_\bl_\bu_\be] [-\b-r\br|-\b--\b-r\bri\big\bgi\bid\bd]
+
+           By default the graph will be autoscaling so that it will adjust the
+           y-axis to the range of the data. You can change this behaviour by
+           explicitly setting the limits. The displayed y-axis will then range
+           at least from l\blo\bow\bwe\ber\br-\b-l\bli\bim\bmi\bit\bt to u\bup\bpp\bpe\ber\br-\b-l\bli\bim\bmi\bit\bt. Autoscaling will still
+           permit those boundaries to be stretched unless the r\bri\big\bgi\bid\bd option is
+           set.
+
+           [-\b-A\bA|-\b--\b-a\bal\blt\bt-\b-a\bau\but\bto\bos\bsc\bca\bal\ble\be]
+
+           Sometimes the default algorithm for selecting the y-axis scale is
+           not satisfactory. Normally the scale is selected from a predefined
+           set of ranges and this fails miserably when you need to graph some-
+           thing like "260 + 0.001 * sin(x)". This option calculates the mini-
+           mum and maximum y-axis from the actual minimum and maximum data
+           values. Our example would display slightly less than "260-0.001" to
+           slightly more than "260+0.001" (this feature was contributed by
+           Sasha Mikheev).
+

+
+           Where "--alt-autoscale" will modify both the absolute maximum AND
+           minimum values, this option will only affect the minimum value. The
+           maximum value, if not defined on the command line, will be 0. This
+           option can be useful when graphing router traffic when the WAN line
+           uses compression, and thus the throughput may be higher than the
+           WAN line speed.
+
+           [-\b-M\bM|-\b--\b-a\bal\blt\bt-\b-a\bau\but\bto\bos\bsc\bca\bal\ble\be-\b-m\bma\bax\bx]
+
+           Where "--alt-autoscale" will modify both the absolute maximum AND
+           minimum values, this option will only affect the maximum value. The
+           minimum value, if not defined on the command line, will be 0. This
+           option can be useful when graphing router traffic when the WAN line
+           uses compression, and thus the throughput may be higher than the
+           WAN line speed.
+
+           [-\b-N\bN|-\b--\b-n\bno\bo-\b-g\bgr\bri\bid\bdf\bfi\bit\bt]
+
+           In order to avoid anti-aliasing effects gridlines are placed on
+           integer pixel values. This is by default done by extending the
+           scale so that gridlines happens to be spaced using an integer num-
+           ber of pixels and also start on an integer pixel value.  This might
+           extend the scale too much for some logarithmic scales and for lin-
+           ear scales where -\b--\b-a\bal\blt\bt-\b-a\bau\but\bto\bos\bsc\bca\bal\ble\be is needed.  Using -\b--\b-n\bno\bo-\b-g\bgr\bri\bid\bdf\bfi\bit\bt
+           disables modification of the scale.

+
+               The x-axis label is quite complex to configure. If you don't
+               have very special needs it is probably best to rely on the
+               autoconfiguration to get this right. You can specify the string
+               "none" to suppress the grid and labels altogether.
+
+               The grid is defined by specifying a certain amount of time in
+               the _\b?_\bT_\bM positions. You can choose from "SECOND", "MINUTE",
+               "HOUR", "DAY", "WEEK", "MONTH" or "YEAR". Then you define how
+               many of these should pass between each line or label.  This
+               pair (_\b?_\bT_\bM_\b:_\b?_\bS_\bT) needs to be specified for the base grid (_\bG_\b?_\b?),
+               the major grid (_\bM_\b?_\b?) and the labels (_\bL_\b?_\b?). For the labels you
+               also must define a precision in _\bL_\bP_\bR and a _\bs_\bt_\br_\bf_\bt_\bi_\bm_\be format
+               string in _\bL_\bF_\bM.  _\bL_\bP_\bR defines where each label will be placed. If
+               it is zero, the label will be placed right under the corre-
+               sponding line (useful for hours, dates etcetera).  If you spec-
+               ify a number of seconds here the label is centered on this
+               interval (useful for Monday, January etcetera).
+
+                --x-grid MINUTE:10:HOUR:1:HOUR:4:0:%X
+
+               This places grid lines every 10 minutes, major grid lines every
+               hour, and labels every 4 hours. The labels are placed under the
+               major grid lines as they specify exactly that time.
+
+                --x-grid HOUR:8:DAY:1:DAY:1:0:%A
+
+               This places grid lines every 8 hours, major grid lines and
+               labels each day. The labels are placed exactly between two
+               major grid lines as they specify the complete day and not just
+               midnight.

+
+               Y-axis grid lines appear at each _\bg_\br_\bi_\bd _\bs_\bt_\be_\bp interval.  Labels
+               are placed every _\bl_\ba_\bb_\be_\bl _\bf_\ba_\bc_\bt_\bo_\br lines.  You can specify "-y none"
+               to suppress the grid and labels altogether.  The default for
+               this option is to automatically select sensible values.
+
+               If you have set --y-grid to 'none' not only the labels get
+               supressed, also the space reserved for the labels is removed.
+               You can still add space manually if you use the --units-length
+               command to explicitly reserve space.

+
+               Place the Y grid dynamically based on the graph's Y range. The
+               algorithm ensures that you always have a grid, that there are
+               enough but not too many grid lines, and that the grid is met-
+               ric. That is the grid lines are placed every 1, 2, 5 or 10
+               units. This parameter will also ensure that you get enough dec-
+               imals displayed even if your graph goes from 69.998 to 70.001.

+
+               This sets the 10**exponent scaling of the y-axis values. Nor-
+               mally, values will be scaled to the appropriate units (k, M,
+               etc.).  However, you may wish to display units always in k
+               (Kilo, 10e3) even if the data is in the M (Mega, 10e6) range,
+               for instance. Value should be an integer which is a multiple of
+               3 between -18 and 18 inclusively.  It is the exponent on the
+               units you wish to use. For example, use 3 to display the y-axis
+               values in k (Kilo, 10e3, thousands), use -6 to display the
+               y-axis values in u (Micro, 10e-6, millionths).  Use a value of
+               0 to prevent any scaling of the y-axis values.
+
+               This option is very effective at confusing the heck out of the
+               default rrdtool autoscaler and grid painter. If rrdtool detects
+               that it is not successful in labeling the graph under the given

+
+           Override the default colors for the standard elements of the graph.
+           The _\bC_\bO_\bL_\bO_\bR_\bT_\bA_\bG is one of "BACK" background, "CANVAS" for the back-
+           ground of the actual graph, "SHADEA" for the left and top border,
+           "SHADEB" for the right and bottom border, "GRID", "MGRID" for the
+           major grid, "FONT" for the color of the font, "AXIS" for the axis
+           of the graph, "FRAME" for the line around the color spots and
+           finally "ARROW" for the arrow head pointing up and forward. Each
+           color is composed out of three hexadecimal numbers specifying its
+           rgb color component (00 is off, FF is maximum) of red, green and
+           blue. Optionally you may add another hexadecimal number specifying
+           the transparency (FF is solid). You may set this option several
+           times to alter multiple defaults.
+
+           A green arrow is made by: "--color ARROW#00FF00"

+
+           This lets you customize which font to use for the various text ele-
+           ments on the RRD graphs. "DEFAULT" sets the default value for all
+           elements, "TITLE" for the title, "AXIS" for the axis labels, "UNIT"
+           for the vertical unit label, "LEGEND" for the graph legend.
+
+           Use Times for the title: "--font TITLE:13:/usr/lib/fonts/times.ttf"
+
+           If you do not give a font string you can modify just the sice of
+           the default font: "--font TITLE:13:".
+
+           If you specify the size 0 then you can modify just the font without
+           touching the size. This is especially usefull for altering the
+           default font without resetting the default fontsizes: "--font
+           DEFAULT:0:/usr/lib/fonts/times.ttf".
+
+           RRDtool comes with a preset default font. You can set the environ-
+           ment variable "RRD_DEFAULT_FONT" if you want to change this.
+
+           Truetype fonts are only supported for PNG output. See below.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+These three instructions extract data values out of the \fB\s-1RRD\s0\fR files,
+optionally altering them (think, for example, of a bytes to bits
+conversion). If so desired, you can also define variables containing
+useful information such as maximum, minimum etcetera. Two of the
+instructions use a language called \fB\s-1RPN\s0\fR which is described in its
+own manual page.
+.PP
+Variable names (\fIvname\fR) must be made up strings of the following characters
+\&\f(CW\*(C`A\-Z, a\-z, 0\-9, \-,_\*(C'\fR and a maximum length of 255 characters.
+.PP
+When picking variable names, make sure you do not choose a name that is
+already taken by an \s-1RPN\s0 operator. A save bet it to use lowercase or
+mixedcase names for variables since operators will always be in uppercase.
+.SH "DEF"
+.IX Header "DEF"
+\&\fB\s-1DEF:\s0\fR\fI<vname>\fR=\fI<rrdfile>\fR:\fI<ds-name>\fR:\fI<\s-1CF\s0>\fR[:step=\fI<step>\fR][:start=\fI<time>\fR][:end=\fI<time>\fR][:reduce=\fI<\f(BI\s-1CF\s0\fI>\fR]
+.PP
+This command fetches data from an \fB\s-1RRD\s0\fR file.  The virtual name
+\&\fIvname\fR can then be used throughout the rest of the script. By
+default, an \fB\s-1RRA\s0\fR which contains the correct consolidated data
+at an appropriate resolution will be chosen.  The resolution can
+be overridden with the \-\-step option.
+The resolution can again be overridden by specifying the \fBstep size\fR.
+The time span of this data is the same as for the graph by default,
+you can override this by specifying \fBstart and end\fR.  Remember to
+escape colons in the time specification!
+.PP
+If the resolution of the data is higher than the resolution of the
+graph, the data will be further consolidated. This may result in
+a graph that spans slightly more time than requested.
+Ideally each point in the graph should correspond with one \fB\s-1CDP\s0\fR
+from an \fB\s-1RRA\s0\fR.  For instance, if your \fB\s-1RRD\s0\fR has an \fB\s-1RRA\s0\fR with
+a resolution of 1800 seconds per \fB\s-1CDP\s0\fR, you should create an
+image with width 400 and time span 400*1800 seconds (use appropriate
+start and end times, such as \f(CW\*(C`\-\-start end\-8days8hours\*(C'\fR).
+.PP
+If consolidation needs to be done, the \fB\s-1CF\s0\fR of the \fB\s-1RRA\s0\fR specified in the
+\&\fB\s-1DEF\s0\fR itself will be used to reduce the data density. This behaviour can
+be changed using \f(CW\*(C`:reduce=\f(CI<\f(CB\s-1CF\s0\f(CI>\f(CW\*(C'\fR.  This optional parameter
+specifies the \fB\s-1CF\s0\fR to use during the data reduction phase.
+.PP
+Example:

+.Vb 4
+\&        DEF:ds0=router.rrd:ds0:AVERAGE
+\&        DEF:ds0weekly=router.rrd:ds0:AVERAGE:step=7200

+.SH "VDEF"
+.IX Header "VDEF"
+\&\fB\s-1VDEF\s0\fR:\fIvname\fR=\fI\s-1RPN\s0 expression\fR
+.PP
+This command returns a value and/or a time according to the \fB\s-1RPN\s0\fR
+statements used. The resulting \fIvname\fR will, depending on the
+functions used, have a value and a time component.  When you use
+this \fIvname\fR in another \fB\s-1RPN\s0\fR expression, you are effectively
+inserting its value just as if you had put a number at that place.
+The variable can also be used in the various graph and print
+elements.
+.PP
+Example: \f(CW\*(C`VDEF:avg=mydata,AVERAGE\*(C'\fR
+.PP
+Note that currently only agregation functions work in \s-1VDEF\s0 rpn expressions.
+Patches to change this are welcome.
+.SH "CDEF"
+.IX Header "CDEF"
+\&\fB\s-1CDEF\s0\fR:\fIvname\fR=\fI\s-1RPN\s0 expression\fR
+.PP
+This command creates a new set of data points (in memory only, not
+in the \fB\s-1RRD\s0\fR file) out of one or more other data series. The \fB\s-1RPN\s0\fR
+instructions are used to evaluate a mathematical function on each
+data point. The resulting \fIvname\fR can then be used further on in
+the script, just as if it were generated by a \fB\s-1DEF\s0\fR instruction.
+.PP
+Example: \f(CW\*(C`CDEF:mydatabits=mydata,8,*\*(C'\fR

+<h1><a name="def">DEF</a></h1>
+<p><strong>DEF:</strong><em>&lt;vname&gt;</em>=<em>&lt;rrdfile&gt;</em>:<em>&lt;ds-name&gt;</em>:<em>&lt;CF&gt;</em>[:step=<em>&lt;step&gt;</em>][:start=<em>&lt;time&gt;</em>][:end=<em>&lt;time&gt;</em>][:reduce=<em>&lt;<strong>CF</strong>&gt;</em>]</p>
+<p>This command fetches data from an <strong>RRD</strong> file.  The virtual name
+<em>vname</em> can then be used throughout the rest of the script. By
+default, an <strong>RRA</strong> which contains the correct consolidated data
+at an appropriate resolution will be chosen.  The resolution can
+be overridden with the <a href="././rrdgraph.html#item_time">--step</a> option.
+The resolution can again be overridden by specifying the <strong>step size</strong>.
+The time span of this data is the same as for the graph by default,
+you can override this by specifying <strong>start and end</strong>.  Remember to
+escape colons in the time specification!</p>
+<p>If the resolution of the data is higher than the resolution of the
+graph, the data will be further consolidated. This may result in
+a graph that spans slightly more time than requested.
+Ideally each point in the graph should correspond with one <strong>CDP</strong>
+from an <strong>RRA</strong>.  For instance, if your <strong>RRD</strong> has an <strong>RRA</strong> with
+a resolution of 1800 seconds per <strong>CDP</strong>, you should create an
+image with width 400 and time span 400*1800 seconds (use appropriate
+start and end times, such as <code>--start end-8days8hours</code>).</p>
+<p>If consolidation needs to be done, the <strong>CF</strong> of the <strong>RRA</strong> specified in the
+<strong>DEF</strong> itself will be used to reduce the data density. This behaviour can
+be changed using <code>:reduce=&lt;CF&gt;</code>.  This optional parameter
+specifies the <strong>CF</strong> to use during the data reduction phase.</p>

+rrdgraph_data - preparing data for graphing in rrdtool graph
+
+=head1 SYNOPSIS
+

+
+B<VDEF>:I<vname>=I<RPN expression>
+
+B<CDEF>:I<vname>=I<RPN expression>
+
+=head1 DESCRIPTION
+
+These three instructions extract data values out of the B<RRD> files,
+optionally altering them (think, for example, of a bytes to bits
+conversion). If so desired, you can also define variables containing
+useful information such as maximum, minimum etcetera. Two of the
+instructions use a language called B<RPN> which is described in its
+own manual page.
+
+Variable names (I<vname>) must be made up strings of the following characters
+C<A-Z, a-z, 0-9, -,_> and a maximum length of 255 characters.
+
+When picking variable names, make sure you do not choose a name that is
+already taken by an RPN operator. A save bet it to use lowercase or
+mixedcase names for variables since operators will always be in uppercase.
+
+=head1 DEF
+
+B<DEF:>I<E<lt>vnameE<gt>>=I<E<lt>rrdfileE<gt>>:I<E<lt>ds-nameE<gt>>:I<E<lt>CFE<gt>>[:step=I<E<lt>stepE<gt>>][:start=I<E<lt>timeE<gt>>][:end=I<E<lt>timeE<gt>>][:reduce=I<E<lt>B<CF>E<gt>>]
+
+This command fetches data from an B<RRD> file.  The virtual name
+I<vname> can then be used throughout the rest of the script. By
+default, an B<RRA> which contains the correct consolidated data
+at an appropriate resolution will be chosen.  The resolution can
+be overridden with the L<--step|rrdgraph/item_Time> option.
+The resolution can again be overridden by specifying the B<step size>.
+The time span of this data is the same as for the graph by default,
+you can override this by specifying B<start and end>.  Remember to
+escape colons in the time specification!
+
+If the resolution of the data is higher than the resolution of the
+graph, the data will be further consolidated. This may result in
+a graph that spans slightly more time than requested.
+Ideally each point in the graph should correspond with one B<CDP>
+from an B<RRA>.  For instance, if your B<RRD> has an B<RRA> with
+a resolution of 1800 seconds per B<CDP>, you should create an
+image with width 400 and time span 400*1800 seconds (use appropriate
+start and end times, such as C<--start end-8days8hours>).
+
+If consolidation needs to be done, the B<CF> of the B<RRA> specified in the
+B<DEF> itself will be used to reduce the data density. This behaviour can
+be changed using C<:reduce=I<E<lt>B<CF>E<gt>>>.  This optional parameter
+specifies the B<CF> to use during the data reduction phase.
+
+Example:
+
+        DEF:ds0=router.rrd:ds0:AVERAGE
+        DEF:ds0weekly=router.rrd:ds0:AVERAGE:step=7200
+        DEF:ds0weekly=router.rrd:ds0:AVERAGE:start=end-1h
+        DEF:ds0weekly=router.rrd:ds0:AVERAGE:start=11\:00:end=start+1h
+
+=head1 VDEF
+
+B<VDEF>:I<vname>=I<RPN expression>
+
+This command returns a value and/or a time according to the B<RPN>
+statements used. The resulting I<vname> will, depending on the
+functions used, have a value and a time component.  When you use
+this I<vname> in another B<RPN> expression, you are effectively
+inserting its value just as if you had put a number at that place.
+The variable can also be used in the various graph and print
+elements.
+
+Example: C<VDEF:avg=mydata,AVERAGE>
+
+Note that currently only agregation functions work in VDEF rpn expressions.
+Patches to change this are welcome.
+
+=head1 CDEF
+
+B<CDEF>:I<vname>=I<RPN expression>
+
+This command creates a new set of data points (in memory only, not
+in the B<RRD> file) out of one or more other data series. The B<RPN>
+instructions are used to evaluate a mathematical function on each
+data point. The resulting I<vname> can then be used further on in
+the script, just as if it were generated by a B<DEF> instruction.
+
+Example: C<CDEF:mydatabits=mydata,8,*>

+       page.
+
+       Variable names (_\bv_\bn_\ba_\bm_\be) must be made up strings of the following charac-
+       ters "A-Z, a-z, 0-9, -,_" and a maximum length of 255 characters.
+
+       When picking variable names, make sure you do not choose a name that is
+       already taken by an RPN operator. A save bet it to use lowercase or
+       mixedcase names for variables since operators will always be in upper-
+       case.

+
+       This command fetches data from an R\bRR\bRD\bD file.  The virtual name _\bv_\bn_\ba_\bm_\be can
+       then be used throughout the rest of the script. By default, an R\bRR\bRA\bA
+       which contains the correct consolidated data at an appropriate resolu-
+       tion will be chosen.  The resolution can be overridden with the --step
+       option.  The resolution can again be overridden by specifying the s\bst\bte\bep\bp
+       s\bsi\biz\bze\be.  The time span of this data is the same as for the graph by
+       default, you can override this by specifying s\bst\bta\bar\brt\bt a\ban\bnd\bd e\ben\bnd\bd.  Remember
+       to escape colons in the time specification!
+
+       If the resolution of the data is higher than the resolution of the
+       graph, the data will be further consolidated. This may result in a
+       graph that spans slightly more time than requested.  Ideally each point
+       in the graph should correspond with one C\bCD\bDP\bP from an R\bRR\bRA\bA.  For instance,
+       if your R\bRR\bRD\bD has an R\bRR\bRA\bA with a resolution of 1800 seconds per C\bCD\bDP\bP, you
+       should create an image with width 400 and time span 400*1800 seconds
+       (use appropriate start and end times, such as "--start
+       end-8days8hours").
+
+       If consolidation needs to be done, the C\bCF\bF of the R\bRR\bRA\bA specified in the
+       D\bDE\bEF\bF itself will be used to reduce the data density. This behaviour can
+       be changed using ":reduce=<CF>".  This optional parameter specifies the
+       C\bCF\bF to use during the data reduction phase.
+
+       Example:
+
+               DEF:ds0=router.rrd:ds0:AVERAGE
+               DEF:ds0weekly=router.rrd:ds0:AVERAGE:step=7200

+
+       This command returns a value and/or a time according to the R\bRP\bPN\bN state-
+       ments used. The resulting _\bv_\bn_\ba_\bm_\be will, depending on the functions used,
+       have a value and a time component.  When you use this _\bv_\bn_\ba_\bm_\be in another
+       R\bRP\bPN\bN expression, you are effectively inserting its value just as if you
+       had put a number at that place.  The variable can also be used in the
+       various graph and print elements.
+
+       Example: "VDEF:avg=mydata,AVERAGE"

+.IX Item "PRINT:vname:format[:strftime]"
+Depending on the context, either the value component or the time
+component of a \fB\s-1VDEF\s0\fR is printed using \fIformat\fR. It is an error
+to specify a \fIvname\fR generated by a \fB\s-1DEF\s0\fR or \fB\s-1CDEF\s0\fR.

+Any text in \fIformat\fR is printed literally with one exception:
+The percent character introduces a formatter string. This string
+can be:

+For printing values:
+.RS 4
+.IP "\fB%%\fR" 4
+.IX Item "%%"
+just prints a literal '%' character
+.IP "\fB%#.#le\fR" 4
+.IX Item "%#.#le"
+prints numbers like 1.2346e+04. The optional integers # denote field
+width and decimal precision.
+.IP "\fB%#.#lf\fR" 4
+.IX Item "%#.#lf"
+prints numbers like 12345.6789, with optional field width
+and precision.
+.IP "\fB%s\fR" 4
+.IX Item "%s"
+place this after \fB%le\fR, \fB%lf\fR or \fB%lg\fR. This will be replaced by the
+appropriate \s-1SI\s0 magnitude unit and the value will be scaled
+accordingly (123456 \-> 123.456 k).
+.IP "\fB%S\fR" 4
+.IX Item "%S"
+is similar to \fB%s\fR. It does, however, use a previously defined
+magnitude unit. If there is no such unit yet, it tries to define
+one (just like \fB%s\fR) unless the value is zero, in which case the magnitude
+unit stays undefined. Thus, formatter strings using \fB%S\fR and no \fB%s\fR
+will all use the same magnitude unit except for zero values.

+If you \s-1PRINT\s0 a \s-1VDEF\s0 value, you can also print the time associated with it by appending the string
+\&\fB:strftime\fR to the format. Note that rrdtool uses the strftime function of your OSs clibrary. This means that
+the conversion specifier may vary. Check the manual page if you are uncertain. The following is a list of
+conversion specifiers usually supported across the board.

+Draw a line of the specified width onto the graph. \fIwidth\fR can be a

+\&'invisibly'. This is useful when stacking something else on top of this
+line. Also optional is the legend box and string which will be printed in

+Plot a tick mark (a vertical line) for each value of \fIvname\fR that is
+non-zero and not *UNKNOWN*. The \fIfraction\fR argument specifies the length of
+the tick mark as a fraction of the y\-axis; the default value is 0.1 (10% of
+the axis). Note that the color specification is not optional. The \s-1TICK\s0 marks normaly
+start at the lower edge of the graphing area. If the fraction is negative they start
+at the upper border of the graphing area.

+.IX Item "SHIFT:vname:offset"
+Using this command \fBRRDtool\fR will graph the following elements
+with the specified offset.  For instance, you can specify an
+offset of (\ 7*24*60*60\ =\ )\ 604'800\ seconds to \*(L"look back\*(R" one
+week. Make sure to tell the viewer of your graph you did this ...

+.PP
+\&\fBSome notes on stacking\fR
+.PP
+When stacking, an element is not placed above the X\-axis but rather
+on top of the previous element.  There must be something to stack
+upon.
+.PP
+You can use an \fBinvisible\fR \s-1LINE\s0 or \s-1AREA\s0 to stacked upon.
+.PP
+An \fBunknown\fR value makes the entire stack unknown from that moment on.
+You don't know where to begin (the unknown value) and therefore do
+not know where to end.
+.PP
+If you want to make sure you will be displaying a certain variable,
+make sure never to stack upon the unknown value.  Use a \s-1CDEF\s0 instruction
+with \fB\s-1IF\s0\fR and \fB\s-1UN\s0\fR to do so.
+.SH "NOTES on legend arguments"
+.IX Header "NOTES on legend arguments"
+.Sh "Escaping the colon"
+.IX Subsection "Escaping the colon"
+A colon ':' in a \fIlegend\fR argument will mark the end of the
+legend. To enter a ':' as part of a legend, the colon must be escaped
+with a backslash '\e:'.  Beware that many environments process
+backslashes themselves, so it may be necessary to write two
+backslashes in order to one being passed onto rrd_graph.
+.Sh "String Formatting"
+.IX Subsection "String Formatting"
+The text printed below the actual graph can be formatted by appending special
+escape characters at the end of a text. When ever such a character occurs,
+all pending text is pushed onto the graph according to the character
+specified.
+.PP
+Valid markers are: \fB\ej\fR for justified, \fB\el\fR for left aligned, \fB\er\fR for
+right aligned, and \fB\ec\fR for centered. In the next section there is an
+example showing how to use centered formatting.
+.PP
+\&\fB\en\fR is a valid alias for \fB\el\fR since incomplete parsing in earlier
+versions of rrdtool lead to this behaviour and a number of people has been using it.
+.PP
+Normally there are two space characters inserted between every two items
+printed into the graph. The space following a string can be suppressed by
+putting a \fB\eg\fR at the end of the string. The \fB\eg\fR also ignores any space
+inside the string if it is at the very end of the string. This can be used
+in connection with \fB%s\fR to suppress empty unit strings.
+.PP
+.Vb 1
+\& GPRINT:a:MAX:%lf%s\eg
+.Ve
+.PP
+A special case is \s-1COMMENT:\s0\fB\es\fR which inserts some additional vertical space
+before placing the next row of legends.
+.PP
+If you are using the proportional font in your graph, you can use tab
+characters or the sequence \fB\et\fR to line-up legend elements. Note that
+the tabs inserted are relative to the start of the current legend
+element!

+<h2><a name="escaping_the_colon">Escaping the colon</a></h2>
+<p>A colon ':' in a <em>legend</em> argument will mark the end of the
+legend. To enter a ':' as part of a legend, the colon must be escaped
+with a backslash '\:'.  Beware that many environments process
+backslashes themselves, so it may be necessary to write two
+backslashes in order to one being passed onto rrd_graph.</p>
+<p>
+</p>
+<h2><a name="string_formatting">String Formatting</a></h2>
+<p>The text printed below the actual graph can be formatted by appending special
+escape characters at the end of a text. When ever such a character occurs,
+all pending text is pushed onto the graph according to the character
+specified.</p>
+<p>Valid markers are: <strong>\j</strong> for justified, <strong>\l</strong> for left aligned, <strong>\r</strong> for
+right aligned, and <strong>\c</strong> for centered. In the next section there is an
+example showing how to use centered formatting.</p>
+<p><strong>\n</strong> is a valid alias for <strong>\l</strong> since incomplete parsing in earlier
+versions of rrdtool lead to this behaviour and a number of people has been using it.</p>
+<p>Normally there are two space characters inserted between every two items
+printed into the graph. The space following a string can be suppressed by
+putting a <strong>\g</strong> at the end of the string. The <strong>\g</strong> also ignores any space
+inside the string if it is at the very end of the string. This can be used
+in connection with <strong>%s</strong> to suppress empty unit strings.</p>
+<pre>
+ GPRINT:a:MAX:%lf%s\g</pre>
+<p>A special case is COMMENT:<strong>\s</strong> which inserts some additional vertical space
+before placing the next row of legends.</p>
+<p>If you are using the proportional font in your graph, you can use tab
+characters or the sequence <strong>\t</strong> to line-up legend elements. Note that
+the tabs inserted are relative to the start of the current legend
+element!</p>

+=head1 DESCRIPTION
+
+These instructions allow you to generate your image or report.
+If you don't use any graph elements, no graph is generated.
+Similarly, no report is generated if you don't use print options.

+
+
+=item B<PRINT:>I<vname>B<:>I<format>[B<:strftime>]
+
+Depending on the context, either the value component or the time
+component of a B<VDEF> is printed using I<format>. It is an error
+to specify a I<vname> generated by a B<DEF> or B<CDEF>.
+
+Any text in I<format> is printed literally with one exception:
+The percent character introduces a formatter string. This string
+can be:
+
+For printing values:
+

+
+=item B<%%>
+
+just prints a literal '%' character
+
+=item B<%#.#le>
+
+prints numbers like 1.2346e+04. The optional integers # denote field
+width and decimal precision.
+
+=item B<%#.#lf>
+
+prints numbers like 12345.6789, with optional field width
+and precision.
+
+=item B<%s>
+
+place this after B<%le>, B<%lf> or B<%lg>. This will be replaced by the
+appropriate SI magnitude unit and the value will be scaled
+accordingly (123456 -> 123.456 k).
+
+=item B<%S>
+
+is similar to B<%s>. It does, however, use a previously defined
+magnitude unit. If there is no such unit yet, it tries to define
+one (just like B<%s>) unless the value is zero, in which case the magnitude
+unit stays undefined. Thus, formatter strings using B<%S> and no B<%s>
+will all use the same magnitude unit except for zero values.
+
+=back
+
+If you PRINT a VDEF value, you can also print the time associated with it by appending the string
+B<:strftime> to the format. Note that rrdtool uses the strftime function of your OSs clibrary. This means that
+the conversion specifier may vary. Check the manual page if you are uncertain. The following is a list of
+conversion specifiers usually supported across the board.

+This is the same as C<PRINT>, but printed inside the graph.
+
+=item B<COMMENT>B<:>I<text>
+
+Text is printed literally in the legend section of the graph. Note that in
+RRDtool 1.2 you have to escape colons in COMMENT text in the same way you
+have to escape them in B<*PRINT> commands by writing B<'\:'>.
+
+=item B<VRULE>B<:>I<time>B<#>I<color> [B<:>I<legend> ]
+
+Draw a vertical line at I<time>.  Its color is composed from three
+hexadecimal numbers specifying the rgb color components (00 is off, FF is
+maximum) red, green and blue followed by an optional alpha. Optionally, a legend box and string is
+printed in the legend section. I<time> may be a number or a variable
+from a B<VDEF>. It is an error to use I<vname>s from B<DEF> or B<CDEF> here.
+
+=item B<HRULE>B<:>I<value>B<#>I<color> [ :I<legend> ]
+
+Draw a horizontal line at I<value>.  HRULE acts much like LINE except that
+will have no effect on the scale of the graph. If a HRULE is outside the
+graphing area it will just not be visible.
+
+=item B<LINE>[I<width>]B<:>I<value>[B<#>I<color>][B<:>[I<legend>][B<:STACK>]]
+
+Draw a line of the specified width onto the graph. I<width> can be a
+floating point number. If the color is not specified, the drawing is done
+'invisibly'. This is useful when stacking something else on top of this
+line. Also optional is the legend box and string which will be printed in
+the legend section if specified. The B<value> can be generated by B<DEF>,
+B<VDEF>, and B<CDEF>.  If the optional B<STACK> modifier is used, this line
+is stacked on top of the previous element which can be a B<LINE> or an
+B<AREA>.
+
+When you do not specify a color, you cannot specify a legend.  Should
+you want to use STACK, use the "LINEx:<value>::STACK" form.
+
+=item B<AREA>B<:>I<value>[B<#>I<color>][B<:>[I<legend>][B<:STACK>]]
+
+See B<LINE>, however the area between the x-axis and the line will
+be filled.
+
+=item B<TICK>B<:>I<vname>B<#>I<rrggbb>[I<aa>][B<:>I<fraction>[B<:>I<legend>]]
+
+Plot a tick mark (a vertical line) for each value of I<vname> that is
+non-zero and not *UNKNOWN*. The I<fraction> argument specifies the length of
+the tick mark as a fraction of the y-axis; the default value is 0.1 (10% of
+the axis). Note that the color specification is not optional. The TICK marks normaly
+start at the lower edge of the graphing area. If the fraction is negative they start
+at the upper border of the graphing area.
+
+=item B<SHIFT>B<:>I<vname>B<:>I<offset>
+
+Using this command B<RRDtool> will graph the following elements
+with the specified offset.  For instance, you can specify an
+offset of S<( 7*24*60*60 = ) 604'800 seconds> to "look back" one
+week. Make sure to tell the viewer of your graph you did this ...
+As with the other graphing elements, you can specify a number or
+a variable here.

+# The size of the canvas is determined by the lesser of
+# L<width and height|rrdgraph/item_Size>.
+#
+# Pie parts will be concatenated, the first one will start at the
+# top and parts will be created clockwise.  The size of the part
+# is defined by the value part of the L<VDEF|rrdgraph_data/VDEF>

+
+B<Some notes on stacking>
+
+When stacking, an element is not placed above the X-axis but rather
+on top of the previous element.  There must be something to stack
+upon.
+
+You can use an B<invisible> LINE or AREA to stacked upon.
+
+An B<unknown> value makes the entire stack unknown from that moment on.
+You don't know where to begin (the unknown value) and therefore do
+not know where to end.
+
+If you want to make sure you will be displaying a certain variable,
+make sure never to stack upon the unknown value.  Use a CDEF instruction
+with B<IF> and B<UN> to do so.
+
+=head1 NOTES on legend arguments
+
+=head2 Escaping the colon
+
+A colon ':' in a I<legend> argument will mark the end of the
+legend. To enter a ':' as part of a legend, the colon must be escaped
+with a backslash '\:'.  Beware that many environments process
+backslashes themselves, so it may be necessary to write two
+backslashes in order to one being passed onto rrd_graph.
+
+=head2 String Formatting
+
+The text printed below the actual graph can be formatted by appending special
+escape characters at the end of a text. When ever such a character occurs,
+all pending text is pushed onto the graph according to the character
+specified.
+
+Valid markers are: B<\j> for justified, B<\l> for left aligned, B<\r> for
+right aligned, and B<\c> for centered. In the next section there is an
+example showing how to use centered formatting.
+
+B<\n> is a valid alias for B<\l> since incomplete parsing in earlier
+versions of rrdtool lead to this behaviour and a number of people has been using it.
+
+Normally there are two space characters inserted between every two items
+printed into the graph. The space following a string can be suppressed by
+putting a B<\g> at the end of the string. The B<\g> also ignores any space
+inside the string if it is at the very end of the string. This can be used
+in connection with B<%s> to suppress empty unit strings.
+
+ GPRINT:a:MAX:%lf%s\g
+
+A special case is COMMENT:B<\s> which inserts some additional vertical space
+before placing the next row of legends.
+
+If you are using the proportional font in your graph, you can use tab
+characters or the sequence B<\t> to line-up legend elements. Note that
+the tabs inserted are relative to the start of the current legend
+element!

+
+           %\b%S\bS  is similar to %\b%s\bs. It does, however, use a previously defined

+           Text is printed literally in the legend section of the graph. Note
+           that in RRDtool 1.2 you have to escape colons in COMMENT text in
+           the same way you have to escape them in *\b*P\bPR\bRI\bIN\bNT\bT commands by writing
+           '\b'\\b\:\b:'\b'.

+       V\bVR\bRU\bUL\bLE\bE:\b:_\bt_\bi_\bm_\be#\b#_\bc_\bo_\bl_\bo_\br [:\b:_\bl_\be_\bg_\be_\bn_\bd ]
+           Draw a vertical line at _\bt_\bi_\bm_\be.  Its color is composed from three
+           hexadecimal numbers specifying the rgb color components (00 is off,
+           FF is maximum) red, green and blue followed by an optional alpha.
+           Optionally, a legend box and string is printed in the legend sec-
+           tion. _\bt_\bi_\bm_\be may be a number or a variable from a V\bVD\bDE\bEF\bF. It is an
+           error to use _\bv_\bn_\ba_\bm_\bes from D\bDE\bEF\bF or C\bCD\bDE\bEF\bF here.
+
+       H\bHR\bRU\bUL\bLE\bE:\b:_\bv_\ba_\bl_\bu_\be#\b#_\bc_\bo_\bl_\bo_\br [ :_\bl_\be_\bg_\be_\bn_\bd ]
+           Draw a horizontal line at _\bv_\ba_\bl_\bu_\be.  HRULE acts much like LINE except
+           that will have no effect on the scale of the graph. If a HRULE is
+           outside the graphing area it will just not be visible.
+
+       L\bLI\bIN\bNE\bE[_\bw_\bi_\bd_\bt_\bh]:\b:_\bv_\ba_\bl_\bu_\be[#\b#_\bc_\bo_\bl_\bo_\br][:\b:[_\bl_\be_\bg_\be_\bn_\bd][:\b:S\bST\bTA\bAC\bCK\bK]]
+           Draw a line of the specified width onto the graph. _\bw_\bi_\bd_\bt_\bh can be a
+           floating point number. If the color is not specified, the drawing
+           is done 'invisibly'. This is useful when stacking something else on
+           top of this line. Also optional is the legend box and string which
+           will be printed in the legend section if specified. The v\bva\bal\blu\bue\be can
+           be generated by D\bDE\bEF\bF, V\bVD\bDE\bEF\bF, and C\bCD\bDE\bEF\bF.  If the optional S\bST\bTA\bAC\bCK\bK modi-
+           fier is used, this line is stacked on top of the previous element
+           which can be a L\bLI\bIN\bNE\bE or an A\bAR\bRE\bEA\bA.
+
+           When you do not specify a color, you cannot specify a legend.
+           Should you want to use STACK, use the "LINEx:<value>::STACK" form.
+
+       A\bAR\bRE\bEA\bA:\b:_\bv_\ba_\bl_\bu_\be[#\b#_\bc_\bo_\bl_\bo_\br][:\b:[_\bl_\be_\bg_\be_\bn_\bd][:\b:S\bST\bTA\bAC\bCK\bK]]
+           See L\bLI\bIN\bNE\bE, however the area between the x-axis and the line will be
+           filled.
+
+       T\bTI\bIC\bCK\bK:\b:_\bv_\bn_\ba_\bm_\be#\b#_\br_\br_\bg_\bg_\bb_\bb[_\ba_\ba][:\b:_\bf_\br_\ba_\bc_\bt_\bi_\bo_\bn[:\b:_\bl_\be_\bg_\be_\bn_\bd]]
+           Plot a tick mark (a vertical line) for each value of _\bv_\bn_\ba_\bm_\be that is
+           non-zero and not *UNKNOWN*. The _\bf_\br_\ba_\bc_\bt_\bi_\bo_\bn argument specifies the
+           length of the tick mark as a fraction of the y-axis; the default
+           value is 0.1 (10% of the axis). Note that the color specification
+           is not optional. The TICK marks normaly start at the lower edge of
+           the graphing area. If the fraction is negative they start at the
+           upper border of the graphing area.
+
+       S\bSH\bHI\bIF\bFT\bT:\b:_\bv_\bn_\ba_\bm_\be:\b:_\bo_\bf_\bf_\bs_\be_\bt
+           Using this command R\bRR\bRD\bDt\bto\boo\bol\bl will graph the following elements with
+           the specified offset.  For instance, you can specify an offset of
+           ( 7*24*60*60 = ) 604'800 seconds to "look back" one week. Make sure
+           to tell the viewer of your graph you did this ...  As with the
+           other graphing elements, you can specify a number or a variable
+           here.
+
+       S\bST\bTA\bAC\bCK\bK:\b:_\bv_\bn_\ba_\bm_\be#\b#_\bc_\bo_\bl_\bo_\br[:\b:_\bl_\be_\bg_\be_\bn_\bd]

+
+       When stacking, an element is not placed above the X-axis but rather on
+       top of the previous element.  There must be something to stack upon.
+
+       You can use an i\bin\bnv\bvi\bis\bsi\bib\bbl\ble\be LINE or AREA to stacked upon.
+
+       An u\bun\bnk\bkn\bno\bow\bwn\bn value makes the entire stack unknown from that moment on.
+       You don't know where to begin (the unknown value) and therefore do not
+       know where to end.
+
+       If you want to make sure you will be displaying a certain variable,
+       make sure never to stack upon the unknown value.  Use a CDEF instruc-
+       tion with I\bIF\bF and U\bUN\bN to do so.

+
+       A colon ':' in a _\bl_\be_\bg_\be_\bn_\bd argument will mark the end of the legend. To
+       enter a ':' as part of a legend, the colon must be escaped with a back-
+       slash '\:'.  Beware that many environments process backslashes them-
+       selves, so it may be necessary to write two backslashes in order to one
+       being passed onto rrd_graph.

+
+       The text printed below the actual graph can be formatted by appending
+       special escape characters at the end of a text. When ever such a char-
+       acter occurs, all pending text is pushed onto the graph according to
+       the character specified.
+
+       Valid markers are: \\b\j\bj for justified, \\b\l\bl for left aligned, \\b\r\br for right
+       aligned, and \\b\c\bc for centered. In the next section there is an example
+       showing how to use centered formatting.
+
+       \\b\n\bn is a valid alias for \\b\l\bl since incomplete parsing in earlier versions
+       of rrdtool lead to this behaviour and a number of people has been using
+       it.
+
+       Normally there are two space characters inserted between every two
+       items printed into the graph. The space following a string can be sup-
+       pressed by putting a \\b\g\bg at the end of the string. The \\b\g\bg also ignores
+       any space inside the string if it is at the very end of the string.
+       This can be used in connection with %\b%s\bs to suppress empty unit strings.
+
+        GPRINT:a:MAX:%lf%s\g
+
+       A special case is COMMENT:\\b\s\bs which inserts some additional vertical
+       space before placing the next row of legends.
+
+       If you are using the proportional font in your graph, you can use tab
+       characters or the sequence \\b\t\bt to line-up legend elements. Note that the
+       tabs inserted are relative to the start of the current legend element!

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+If you have ever used a traditional \s-1HP\s0 calculator you already know
+\&\fB\s-1RPN\s0\fR. The idea behind \fB\s-1RPN\s0\fR is that you have a stack and push
+your data onto this stack. Whenever you execute an operation, it
+takes as many elements from the stack as needed. Pushing is done
+implicitly, so whenever you specify a number or a variable, it gets
+pushed onto the stack automatically.
+.PP
+At the end of the calculation there should be one and only one value left on
+the stack.  This is the outcome of the function and this is what is put into
+the \fIvname\fR.  For \fB\s-1CDEF\s0\fR instructions, the stack is processed for each
+data point on the graph. \fB\s-1VDEF\s0\fR instructions work on an entire data set in
+one run. Note, that currently \fB\s-1VDEF\s0\fR instructions only support a limited
+list of functions.
+.PP
+Example: \f(CW\*(C`VDEF:maximum=mydata,MAXIMUM\*(C'\fR
+.PP
+This will set variable \*(L"maximum\*(R" which you now can use in the rest
+of your \s-1RRD\s0 script.
+.PP
+Example: \f(CW\*(C`CDEF:mydatabits=mydata,8,*\*(C'\fR
+.PP
+This means:  push variable \fImydata\fR, push the number 8, execute
+the operator \fI*\fR. The operator needs two elements and uses those
+to return one value.  This value is then stored in \fImydatabits\fR.
+As you may have guessed, this instruction means nothing more than
+\&\fImydatabits = mydata * 8\fR.  The real power of \fB\s-1RPN\s0\fR lies in the
+fact that it is always clear in which order to process the input.
+For expressions like \f(CW\*(C`a = b + 3 * 5\*(C'\fR you need to multiply 3 with

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>If you have ever used a traditional HP calculator you already know
+<strong>RPN</strong>. The idea behind <strong>RPN</strong> is that you have a stack and push
+your data onto this stack. Whenever you execute an operation, it
+takes as many elements from the stack as needed. Pushing is done
+implicitly, so whenever you specify a number or a variable, it gets
+pushed onto the stack automatically.</p>
+<p>At the end of the calculation there should be one and only one value left on
+the stack.  This is the outcome of the function and this is what is put into
+the <em>vname</em>.  For <strong>CDEF</strong> instructions, the stack is processed for each
+data point on the graph. <strong>VDEF</strong> instructions work on an entire data set in
+one run. Note, that currently <strong>VDEF</strong> instructions only support a limited
+list of functions.</p>
+<p>Example: <code>VDEF:maximum=mydata,MAXIMUM</code></p>
+<p>This will set variable ``maximum'' which you now can use in the rest
+of your RRD script.</p>
+<p>Example: <code>CDEF:mydatabits=mydata,8,*</code></p>
+<p>This means:  push variable <em>mydata</em>, push the number 8, execute
+the operator <em>*</em>. The operator needs two elements and uses those
+to return one value.  This value is then stored in <em>mydatabits</em>.
+As you may have guessed, this instruction means nothing more than
+<em>mydatabits = mydata * 8</em>.  The real power of <strong>RPN</strong> lies in the
+fact that it is always clear in which order to process the input.
+For expressions like <code>a = b + 3 * 5</code> you need to multiply 3 with
+5 first before you add <em>b</em> to get <em>a</em>. However, with parentheses
+you could change this order: <code>a = (b + 3) * 5</code>. In <strong>RPN</strong>, you
+would do <code>a = b, 3, +, 5, *</code> without the need for parentheses.</p>

+=head1 NAME
+
+rrdgraph_rpn - About RPN Math in rrdtool graph
+
+=head1 SYNOPSIS
+
+I<RPN expression>:=I<vname>|I<operator>|I<value>[,I<RPN expression>]
+
+=head1 DESCRIPTION
+
+If you have ever used a traditional HP calculator you already know
+B<RPN>. The idea behind B<RPN> is that you have a stack and push
+your data onto this stack. Whenever you execute an operation, it
+takes as many elements from the stack as needed. Pushing is done
+implicitly, so whenever you specify a number or a variable, it gets
+pushed onto the stack automatically.
+
+At the end of the calculation there should be one and only one value left on
+the stack.  This is the outcome of the function and this is what is put into
+the I<vname>.  For B<CDEF> instructions, the stack is processed for each
+data point on the graph. B<VDEF> instructions work on an entire data set in
+one run. Note, that currently B<VDEF> instructions only support a limited
+list of functions.
+
+Example: C<VDEF:maximum=mydata,MAXIMUM>
+
+This will set variable "maximum" which you now can use in the rest
+of your RRD script.
+
+Example: C<CDEF:mydatabits=mydata,8,*>
+
+This means:  push variable I<mydata>, push the number 8, execute
+the operator I<*>. The operator needs two elements and uses those
+to return one value.  This value is then stored in I<mydatabits>.
+As you may have guessed, this instruction means nothing more than
+I<mydatabits = mydata * 8>.  The real power of B<RPN> lies in the
+fact that it is always clear in which order to process the input.
+For expressions like C<a = b + 3 * 5> you need to multiply 3 with
+5 first before you add I<b> to get I<a>. However, with parentheses
+you could change this order: C<a = (b + 3) * 5>. In B<RPN>, you
+would do C<a = b, 3, +, 5, *> without the need for parentheses.
+
+=head1 OPERATORS
+
+=over 4
+
+=item Boolean operators
+
+B<LT, LE, GT, GE, EQ, NE>
+
+Pop two elements from the stack, compare them for the selected condition
+and return 1 for true or 0 for false. Comparing an I<unknown> or an
+I<infinite> value will always result in 0 (false).
+
+B<UN, ISINF>
+
+Pop one element from the stack, compare this to I<unknown> respectively
+to I<positive or negative infinity>. Returns 1 for true or 0 for false.
+
+B<IF>
+
+Pops three elements from the stack.  If the element popped last is 0
+(false), the value popped first is pushed back onto the stack,
+otherwise the value popped second is pushed back. This does, indeed,
+mean that any value other than 0 is considered to be true.
+
+Example: C<A,B,C,IF> should be read as C<if (A) then (B) else (C)>
+
+Z<>
+
+=item Comparing values
+
+B<MIN, MAX>
+
+Pops two elements from the stack and returns the smaller or larger,
+respectively.  Note that I<infinite> is larger than anything else.
+If one of the input numbers is I<unknown> then the result of the operation will be
+I<unknown> too.
+
+B<LIMIT>
+
+Pops two elements from the stack and uses them to define a range.
+Then it pops another element and if it falls inside the range, it
+is pushed back. If not, an I<unknown> is pushed.
+
+The range defined includes the two boundaries (so: a number equal
+to one of the boundaries will be pushed back). If any of the three
+numbers involved is either I<unknown> or I<infinite> this function
+will always return an I<unknown>
+
+Example: C<CDEF:a=alpha,0,100,LIMIT> will return I<unknown> if
+alpha is lower than 0 or if it is higher than 100.
+
+Z<>
+
+=item Arithmetics
+
+B<+, -, *, /, %>
+
+Add, subtract, multiply, divide, modulo
+
+B<SIN, COS, LOG, EXP, SQRT>
+
+Sine and cosine (input in radians), log and exp (natural logarithm),
+square root.
+
+B<ATAN>
+
+Arctangent (output in radians).
+
+B<ATAN2>
+
+Arctangent of y,x components (output in radians).
+This pops one element from the stack, the x (cosine) component, and then
+a second, which is the y (sine) component.
+It then pushes the arctangent of their ratio, resolving the ambiguity between
+quadrants.
+
+Example: C<CDEF:angle=Y,X,ATAN2,RAD2DEG> will convert C<X,Y>
+components into an angle in degrees.
+
+B<FLOOR, CEIL>
+
+Round down or up to the nearest integer.
+
+B<DEG2RAD, RAD2DEG>
+
+Convert angle in degrees to radians, or radians to degrees.
+
+B<ABS>
+
+Take the absolute value.
+
+=item Set Operations
+
+B<SORT, REV>
+
+Pop one element from the stack.  This is the I<count> of items to be sorted
+(or reversed).  The top I<count> of the remaining elements are then sorted
+(or reversed) in place on the stack.
+
+Example: C<CDEF:x=v1,v2,v3,v4,v5,v6,6,SORT,POP,5,REV,POP,+,+,+,4,/> will
+compute the average of the values v1 to v6 after removing the smallest and
+largest.
+
+B<AVG>
+
+Pop one element (I<count>) from the stack. Now pop I<count> elements and build the
+average, ignoring all UNKNOWN values in the process.
+
+Example: C<CDEF:x=a,b,c,d,4,AVG>
+
+B<TREND>
+
+Create a "sliding window" average of another data series.
+
+Usage:
+CDEF:smoothed=x,1800,TREND
+
+This will create a half-hour (1800 second) sliding window average of x.  The
+average is essentially computed as shown here:
+
+                 +---!---!---!---!---!---!---!---!--->
+                                                     now
+                       delay     t0
+                 <--------------->
+                         delay       t1
+                     <--------------->
+                              delay      t2
+                         <--------------->
+
+
+     Value at sample (t0) will be the average between (t0-delay) and (t0)
+     Value at sample (t1) will be the average between (t1-delay) and (t1)
+     Value at sample (t2) will be the average between (t2-delay) and (t2)
+
+=item Special values
+
+B<UNKN>
+
+Pushes an unknown value on the stack
+
+B<INF, NEGINF>
+
+Pushes a positive or negative infinite value on the stack. When
+such a value is graphed, it appears at the top or bottom of the
+graph, no matter what the actual value on the y-axis is.
+
+B<PREV>
+
+Pushes an I<unknown> value if this is the first value of a data
+set or otherwise the result of this B<CDEF> at the previous time
+step. This allows you to do calculations across the data.  This
+function cannot be used in B<VDEF> instructions.
+
+B<PREV(vname)>
+
+Pushes an I<unknown> value if this is the first value of a data
+set or otherwise the result of the vname variable at the previous time
+step. This allows you to do calculations across the data. This
+function cannot be used in B<VDEF> instructions.
+
+B<COUNT>
+
+Pushes the number 1 if this is the first value of the data set, the
+number 2 if it is the second, and so on. This special value allows
+you to make calculations based on the position of the value within
+the data set. This function cannot be used in B<VDEF> instructions.
+
+=item Time
+
+Time inside RRDtool is measured in seconds since the epoch. The
+epoch is defined to be S<C<Thu Jan  1 00:00:00 UTC 1970>>.
+
+B<NOW>
+
+Pushes the current time on the stack.
+
+B<TIME>
+
+Pushes the time the currently processed value was taken at onto the stack.
+
+B<LTIME>
+
+Takes the time as defined by B<TIME>, applies the time zone offset
+valid at that time including daylight saving time if your OS supports
+it, and pushes the result on the stack.  There is an elaborate example
+in the examples section below on how to use this.
+

+
+Return the corresponding value, MAXIMUM and MINIMUM also return
+the first occurrence of that value in the time component.
+
+Example: C<VDEF:avg=mydata,AVERAGE>
+
+=item LAST, FIRST
+
+Return the last/first value including its time.  The time for
+FIRST is actually the start of the corresponding interval, whereas
+LAST returns the end of the corresponding interval.
+
+Example: C<VDEF:first=mydata,FIRST>
+
+=item TOTAL
+
+Returns the rate from each defined time slot multiplied with the
+step size.  This can, for instance, return total bytes transfered
+when you have logged bytes per second. The time component returns
+the number of seconds.
+
+Example: C<VDEF:total=mydata,TOTAL>
+
+=item PERCENT
+
+This should follow a B<DEF> or B<CDEF> I<vname>. The I<vname> is popped,

+data set is then sorted and the value returned is chosen such that
+I<percentage> percent of the values is lower or equal than the result.
+I<Unknown> values are considered lower than any finite number for this

+
+       Example: "VDEF:maximum=mydata,MAXIMUM"
+
+       This will set variable "maximum" which you now can use in the rest of
+       your RRD script.
+
+       Example: "CDEF:mydatabits=mydata,8,*"
+
+       This means:  push variable _\bm_\by_\bd_\ba_\bt_\ba, push the number 8, execute the oper-
+       ator _\b*. The operator needs two elements and uses those to return one
+       value.  This value is then stored in _\bm_\by_\bd_\ba_\bt_\ba_\bb_\bi_\bt_\bs.  As you may have
+       guessed, this instruction means nothing more than _\bm_\by_\bd_\ba_\bt_\ba_\bb_\bi_\bt_\bs _\b= _\bm_\by_\bd_\ba_\bt_\ba _\b*

+       you need to multiply 3 with 5 first before you add _\bb to get _\ba. However,
+       with parentheses you could change this order: "a = (b + 3) * 5". In
+       R\bRP\bPN\bN, you would do "a = b, 3, +, 5, *" without the need for parentheses.

+
+           Pop two elements from the stack, compare them for the selected con-
+           dition and return 1 for true or 0 for false. Comparing an _\bu_\bn_\bk_\bn_\bo_\bw_\bn
+           or an _\bi_\bn_\bf_\bi_\bn_\bi_\bt_\be value will always result in 0 (false).
+
+           U\bUN\bN,\b, I\bIS\bSI\bIN\bNF\bF
+
+           Pop one element from the stack, compare this to _\bu_\bn_\bk_\bn_\bo_\bw_\bn respec-

+           for false.
+
+           I\bIF\bF
+
+           Pops three elements from the stack.  If the element popped last is
+           0 (false), the value popped first is pushed back onto the stack,
+           otherwise the value popped second is pushed back. This does,
+           indeed, mean that any value other than 0 is considered to be true.
+
+           Example: "A,B,C,IF" should be read as "if (A) then (B) else (C)"

+       Comparing values

+
+           Pops two elements from the stack and returns the smaller or larger,
+           respectively.  Note that _\bi_\bn_\bf_\bi_\bn_\bi_\bt_\be is larger than anything else.  If
+           one of the input numbers is _\bu_\bn_\bk_\bn_\bo_\bw_\bn then the result of the opera-

+
+           L\bLI\bIM\bMI\bIT\bT
+
+           Pops two elements from the stack and uses them to define a range.
+           Then it pops another element and if it falls inside the range, it
+           is pushed back. If not, an _\bu_\bn_\bk_\bn_\bo_\bw_\bn is pushed.
+
+           The range defined includes the two boundaries (so: a number equal
+           to one of the boundaries will be pushed back). If any of the three
+           numbers involved is either _\bu_\bn_\bk_\bn_\bo_\bw_\bn or _\bi_\bn_\bf_\bi_\bn_\bi_\bt_\be this function will
+           always return an _\bu_\bn_\bk_\bn_\bo_\bw_\bn
+
+           Example: "CDEF:a=alpha,0,100,LIMIT" will return _\bu_\bn_\bk_\bn_\bo_\bw_\bn if alpha is

+
+           Sine and cosine (input in radians), log and exp (natural loga-
+           rithm), square root.
+
+           A\bAT\bTA\bAN\bN
+
+           Arctangent (output in radians).
+
+           A\bAT\bTA\bAN\bN2\b2
+
+           Arctangent of y,x components (output in radians).  This pops one
+           element from the stack, the x (cosine) component, and then a sec-
+           ond, which is the y (sine) component.  It then pushes the arctan-
+           gent of their ratio, resolving the ambiguity between quadrants.
+
+           Example: "CDEF:angle=Y,X,ATAN2,RAD2DEG" will convert "X,Y" compo-
+           nents into an angle in degrees.

+
+           Pop one element from the stack.  This is the _\bc_\bo_\bu_\bn_\bt of items to be
+           sorted (or reversed).  The top _\bc_\bo_\bu_\bn_\bt of the remaining elements are
+           then sorted (or reversed) in place on the stack.
+
+           Example: "CDEF:x=v1,v2,v3,v4,v5,v6,6,SORT,POP,5,REV,POP,+,+,+,4,/"
+           will compute the average of the values v1 to v6 after removing the
+           smallest and largest.
+
+           A\bAV\bVG\bG
+
+           Pop one element (_\bc_\bo_\bu_\bn_\bt) from the stack. Now pop _\bc_\bo_\bu_\bn_\bt elements and
+           build the average, ignoring all UNKNOWN values in the process.
+
+           Example: "CDEF:x=a,b,c,d,4,AVG"
+
+           T\bTR\bRE\bEN\bND\bD
+
+           Create a "sliding window" average of another data series.
+
+           Usage: CDEF:smoothed=x,1800,TREND
+
+           This will create a half-hour (1800 second) sliding window average
+           of x.  The average is essentially computed as shown here:

+                Value at sample (t2) will be the average between (t2-delay) and (t2)
+
+       Special values
+           U\bUN\bNK\bKN\bN
+
+           Pushes an unknown value on the stack
+
+           I\bIN\bNF\bF,\b, N\bNE\bEG\bGI\bIN\bNF\bF
+
+           Pushes a positive or negative infinite value on the stack. When
+           such a value is graphed, it appears at the top or bottom of the
+           graph, no matter what the actual value on the y-axis is.
+
+           P\bPR\bRE\bEV\bV
+
+           Pushes an _\bu_\bn_\bk_\bn_\bo_\bw_\bn value if this is the first value of a data set or
+           otherwise the result of this C\bCD\bDE\bEF\bF at the previous time step. This
+           allows you to do calculations across the data.  This function can-
+           not be used in V\bVD\bDE\bEF\bF instructions.
+
+           P\bPR\bRE\bEV\bV(\b(v\bvn\bna\bam\bme\be)\b)
+
+           Pushes an _\bu_\bn_\bk_\bn_\bo_\bw_\bn value if this is the first value of a data set or
+           otherwise the result of the vname variable at the previous time
+           step. This allows you to do calculations across the data. This
+           function cannot be used in V\bVD\bDE\bEF\bF instructions.
+
+           C\bCO\bOU\bUN\bNT\bT
+
+           Pushes the number 1 if this is the first value of the data set, the
+           number 2 if it is the second, and so on. This special value allows
+           you to make calculations based on the position of the value within
+           the data set. This function cannot be used in V\bVD\bDE\bEF\bF instructions.
+
+       Time
+           Time inside RRDtool is measured in seconds since the epoch. The
+           epoch is defined to be "Thu Jan 1 00:00:00 UTC 1970".
+
+           N\bNO\bOW\bW
+
+           Pushes the current time on the stack.
+
+           T\bTI\bIM\bME\bE
+
+           Pushes the time the currently processed value was taken at onto the
+           stack.
+
+           L\bLT\bTI\bIM\bME\bE
+
+           Takes the time as defined by T\bTI\bIM\bME\bE, applies the time zone offset
+           valid at that time including daylight saving time if your OS sup-
+           ports it, and pushes the result on the stack.  There is an elabo-
+           rate example in the examples section below on how to use this.
+
+       Processing the stack directly
+           D\bDU\bUP\bP,\b, P\bPO\bOP\bP,\b, E\bEX\bXC\bC
+
+           Duplicate the top element, remove the top element, exchange the two
+           top elements.
+
+
+
+V\bVA\bAR\bRI\bIA\bAB\bBL\bLE\bES\bS
+       These operators work only on V\bVD\bDE\bEF\bF statements. Note that currently ONLY
+       these work for V\bVD\bDE\bEF\bF.
+
+       MAXIMUM, MINIMUM, AVERAGE
+           Return the corresponding value, MAXIMUM and MINIMUM also return the
+           first occurrence of that value in the time component.
+
+           Example: "VDEF:avg=mydata,AVERAGE"
+
+       LAST, FIRST
+           Return the last/first value including its time.  The time for FIRST
+           is actually the start of the corresponding interval, whereas LAST
+           returns the end of the corresponding interval.
+
+           Example: "VDEF:first=mydata,FIRST"
+
+       TOTAL
+           Returns the rate from each defined time slot multiplied with the
+           step size.  This can, for instance, return total bytes transfered
+           when you have logged bytes per second. The time component returns
+           the number of seconds.
+
+           Example: "VDEF:total=mydata,TOTAL"
+
+       PERCENT
+           This should follow a D\bDE\bEF\bF or C\bCD\bDE\bEF\bF _\bv_\bn_\ba_\bm_\be. The _\bv_\bn_\ba_\bm_\be is popped,
+           another number is popped which is a certain percentage (0..100).
+           The data set is then sorted and the value returned is chosen such
+           that _\bp_\be_\br_\bc_\be_\bn_\bt_\ba_\bg_\be percent of the values is lower or equal than the
+           result.  _\bU_\bn_\bk_\bn_\bo_\bw_\bn values are considered lower than any finite number
+           for this purpose so if this operator returns an _\bu_\bn_\bk_\bn_\bo_\bw_\bn you have
+           quite a lot of them in your data.  I\bIn\bnf\bfinite numbers are lesser, or
+           more, than the finite numbers and are always more than the _\bU_\bn_\bk_\bn_\bo_\bw_\bn
+           numbers.  (NaN < -INF < finite values < INF)
+
+           Example: "VDEF:perc95=mydata,95,PERCENT"
+
+       LSLSLOPE, LSLINT, LSLCORREL
+           Return the parameters for a L\bLeast S\bSquares L\bLine _\b(_\by _\b= _\bm_\bx _\b+_\bb_\b) which
+           approximate the provided dataset.  LSLSLOPE is the slope _\b(_\bm_\b) of the
+           line related to the COUNT position of the data.  LSLINT is the
+           y-intercept _\b(_\bb_\b), which happens also to be the first data point on
+           the graph. LSLCORREL is the Correlation Coefficient (also know as
+           Pearson's Product Moment Correlation Coefficient).  It will range
+           from 0 to +/-1 and represents the quality of fit for the approxima-
+           tion.
+
+           Example: "VDEF:slope=mydata,LSLSLOPE"

+=head1 NAME
+
+rrdinfo - extract header information from an RRD
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<info> I<filename.rrd>
+
+=head1 DESCRIPTION
+
+The B<info> function prints the header information from an RRD in
+a parsing friendly format.
+
+Check L<rrdcreate> if you are uncertain about the meaning of the
+individual keys.
+
+=head1 EXAMPLE
+
+This is the output generated by running B<info> on a simple RRD which
+contains two data sources and one RRA. Note that the number after the
+I<last_update> keyword is in seconds since 1970. The string B<NaN>
+stands for I<*UNKNOWN*> data. In the example it means that this RRD
+has neither minimum nor maximum values defined for either of its
+data sources.

+       It is possible to abuse this tool and get strange results by first
+       removing some rows and then reinserting the same amount (effectively
+       clearing them to be Unknown). You may thus end up with unknown data in
+       one RRA while at the same timestamp this data is available in another
+       RRA.

+.TH RRDTHREADS 1 "2007-11-20" "1.2.26" "rrdtool"
+.SH "NAME"
+rrdthreads \- Provisions for linking the RRD library to use in multi\-threaded programs
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+Using librrd in multi-threaded programs requires some extra
+precautions, as the \s-1RRD\s0 library in its original form was not
+thread-safe at all. This document describes requirements and pitfalls
+on the way to use the multi-threaded version of librrd in your own
+programs. It also gives hints for future \s-1RRD\s0 development to keep the
+library thread\-safe.
+.PP
+Currently only some \s-1RRD\s0 operations are implemented in a thread-safe
+way. They all end in the usual "\f(CW\*(C`_r\*(C'\fR" suffix.
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+In order to use librrd in multi-threaded programs you must:
+.IP "\(bu" 4
+Link with \fIlibrrd_th\fR instead of \fIlibrrd\fR (use \f(CW\*(C`\-lrrd_th\*(C'\fR when
+linking)
+.IP "\(bu" 4
+Use the "\f(CW\*(C`_r\*(C'\fR" functions instead of the normal API-functions
+.IP "\(bu" 4
+Do not use any at-style time specifications. Parsing of such time
+specifications is terribly non\-thread\-safe.
+.IP "\(bu" 4
+Never use non *\f(CW\*(C`_r\*(C'\fR functions unless it is explicitly documented that
+the function is tread\-safe.
+.IP "\(bu" 4
+Every thread \s-1SHOULD\s0 call \f(CW\*(C`rrd_get_context()\*(C'\fR before its first call to
+any \f(CW\*(C`librrd_th\*(C'\fR function in order to set up thread specific data. This
+is not strictly required, but it is the only way to test if memory
+allocation can be done by this function. Otherwise the program may die
+with a \s-1SIGSEGV\s0 in a low-memory situation.
+.IP "\(bu" 4
+Always call \f(CW\*(C`rrd_error_clear()\*(C'\fR before any call to the
+library. Otherwise the call might fail due to some earlier error.
+.Sh "\s-1NOTES\s0 \s-1FOR\s0 \s-1RRD\s0 \s-1CONTRIBUTORS\s0"
+.IX Subsection "NOTES FOR RRD CONTRIBUTORS"
+Some precautions must be followed when developing \s-1RRD\s0 from now on:
+.IP "\(bu" 4
+Only use thread-safe functions in library code. Many often used libc
+functions aren't thread\-safe. Take care in the following
+situations or when using the following library functions:

+
+rrdthreads - Provisions for linking the RRD library to use in multi-threaded programs
+
+=head1 SYNOPSIS
+
+Using librrd in multi-threaded programs requires some extra
+precautions, as the RRD library in its original form was not
+thread-safe at all. This document describes requirements and pitfalls
+on the way to use the multi-threaded version of librrd in your own
+programs. It also gives hints for future RRD development to keep the
+library thread-safe.
+
+Currently only some RRD operations are implemented in a thread-safe
+way. They all end in the usual "C<_r>" suffix.
+
+=head1 DESCRIPTION
+
+In order to use librrd in multi-threaded programs you must:
+
+=over
+
+=item *
+
+Link with F<librrd_th> instead of F<librrd> (use C<-lrrd_th> when
+linking)
+
+=item *
+
+Use the "C<_r>" functions instead of the normal API-functions
+
+=item *
+
+Do not use any at-style time specifications. Parsing of such time
+specifications is terribly non-thread-safe.
+
+=item *
+
+Never use non *C<_r> functions unless it is explicitly documented that
+the function is tread-safe.
+
+=item *
+
+Every thread SHOULD call C<rrd_get_context()> before its first call to
+any C<librrd_th> function in order to set up thread specific data. This
+is not strictly required, but it is the only way to test if memory
+allocation can be done by this function. Otherwise the program may die
+with a SIGSEGV in a low-memory situation.
+
+=item *
+
+Always call C<rrd_error_clear()> before any call to the
+library. Otherwise the call might fail due to some earlier error.

+
+=head2 NOTES FOR RRD CONTRIBUTORS

+
+Only use thread-safe functions in library code. Many often used libc

+
+=item *
+
+Time functions: C<asctime>, C<ctime>, C<gmtime>, C<localtime>: use

+       Using librrd in multi-threaded programs requires some extra precau-

+       gives hints for future RRD development to keep the library thread-safe.
+
+       Currently only some RRD operations are implemented in a thread-safe
+       way. They all end in the usual ""_r"" suffix.

+       In order to use librrd in multi-threaded programs you must:
+
+       ·   Link with _\bl_\bi_\bb_\br_\br_\bd_\b__\bt_\bh instead of _\bl_\bi_\bb_\br_\br_\bd (use "-lrrd_th" when linking)
+
+       ·   Use the ""_r"" functions instead of the normal API-functions
+
+       ·   Do not use any at-style time specifications. Parsing of such time
+           specifications is terribly non-thread-safe.
+
+       ·   Never use non *"_r" functions unless it is explicitly documented
+           that the function is tread-safe.
+
+       ·   Every thread SHOULD call "rrd_get_context()" before its first call
+           to any "librrd_th" function in order to set up thread specific
+           data. This is not strictly required, but it is the only way to test
+           if memory allocation can be done by this function. Otherwise the
+           program may die with a SIGSEGV in a low-memory situation.
+
+       ·   Always call "rrd_error_clear()" before any call to the library.
+           Otherwise the call might fail due to some earlier error.

+
+           ·   The "getpw*", "getgr*", "gethost*" function families (and some
+               more "get*" functions) are not thread-safe: use the *"_r" vari-
+               ants
+
+           ·   Time functions: "asctime", "ctime", "gmtime", "localtime": use

+
+           ·   "strtok": use "strtok_r"

+
+       ·   A header file named _\br_\br_\bd_\b__\bi_\bs_\b__\bt_\bh_\br_\be_\ba_\bd_\b__\bs_\ba_\bf_\be_\b._\bh is provided that works
+           with the GNU C-preprocessor to "poison" some of the most common

+           Just include this header in source files you want to keep

+
+       ·   Do not introduce global variables!
+

+
+       ·   Do not use "getopt" or "getopt_long" in *"_r" (neither directly nor
+           indirectly).
+
+           "getopt" uses global variables and behaves badly in a multi-
+           threaded application when called concurrently. Instead provide a
+           *_r function taking all options as function parameters. You may
+           provide argc and **argv arguments for variable length argument
+           lists. See "rrd_update_r" as an example.
+
+       ·   Do not use the "parsetime" function!
+
+           It uses lots of global variables. You may use it in functions not
+           designed to be thread-safe, like in functions wrapping the "_r"

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+.Sh "\s-1OVERVIEW\s0"
+.IX Subsection "OVERVIEW"
+It is pretty easy to gather status information from all sorts of
+things, ranging from the temperature in your office to the number of
+octets which have passed through the \s-1FDDI\s0 interface of your
+router. But it is not so trivial to store this data in an efficient and
+systematic manner. This is where \fBRRDtool\fR comes in handy. It lets you
+\&\fIlog and analyze\fR the data you gather from all kinds of data-sources
+(\fB\s-1DS\s0\fR). The data analysis part of RRDtool is based on the ability to
+quickly generate graphical representations of the data values
+collected over a definable time period.
+.PP
+In this man page you will find general information on the design and
+functionality of the Round Robin Database Tool (RRDtool). For a more
+detailed description of how to use the individual functions of
+\&\fBRRDtool\fR check the corresponding man page.
+.PP
+For an introduction to the usage of RRDtool make sure you consult the
+rrdtutorial.
+.Sh "\s-1FUNCTIONS\s0"
+.IX Subsection "FUNCTIONS"
+While the man pages talk of command line switches you have to set in
+order to make \fBRRDtool\fR work it is important to note that
+\&\fBRRDtool\fR can be remotely controlled through a set of pipes. This
+saves a considerable amount of startup time when you plan to make
+\&\fBRRDtool\fR do a lot of things quickly. Check the section on \*(L"Remote Control\*(R" further down. There is also a number of language bindings
+for RRDtool which allow you to use it directly from perl, python, tcl,
+php, etc.
+.IP "\fBcreate\fR" 8
+.IX Item "create"
+Set up a new Round Robin Database (\s-1RRD\s0). Check rrdcreate.
+.IP "\fBupdate\fR" 8
+.IX Item "update"
+Store new data values into an \s-1RRD\s0. Check rrdupdate.
+.IP "\fBupdatev\fR" 8
+.IX Item "updatev"
+Operationally equivalent to \fBupdate\fR except for output. Check rrdupdate.
+.IP "\fBgraph\fR" 8
+.IX Item "graph"
+Create a graph from data stored in one or several RRDs. Apart from
+generating graphs, data can also be extracted to stdout. Check rrdgraph.
+.IP "\fBdump\fR" 8
+.IX Item "dump"
+Dump the contents of an \s-1RRD\s0 in plain \s-1ASCII\s0. In connection with restore
+you can use this to move an \s-1RRD\s0 from one computer architecture to
+another.  Check rrddump.
+.IP "\fBrestore\fR" 8
+.IX Item "restore"
+Restore an \s-1RRD\s0 in \s-1XML\s0 format to a binary \s-1RRD\s0. Check rrdrestore
+.IP "\fBfetch\fR" 8
+.IX Item "fetch"
+Get data for a certain time period from a \s-1RRD\s0. The graph function
+uses fetch to retrieve its data from an \s-1RRD\s0. Check rrdfetch.

+rrdcgi.
+.Sh "\s-1HOW\s0 \s-1DOES\s0 \s-1RRDTOOL\s0 \s-1WORK\s0?"
+.IX Subsection "HOW DOES RRDTOOL WORK?"
+.IP "Data Acquisition" 8
+.IX Item "Data Acquisition"
+When monitoring the state of a system, it is convenient to have the
+data available at a constant time interval. Unfortunately, you may not
+always be able to fetch data at exactly the time you want
+to. Therefore \fBRRDtool\fR lets you update the logfile at any time you
+want. It will automatically interpolate the value of the data-source
+(\fB\s-1DS\s0\fR) at the latest official time-slot (intervall) and write this
+interpolated value to the log. The original value you have supplied is
+stored as well and is also taken into account when interpolating the
+next log entry.
+.IP "Consolidation" 8
+.IX Item "Consolidation"
+You may log data at a 1 minute interval, but you might also be
+interested to know the development of the data over the last year. You
+could do this by simply storing the data in 1 minute intervals for the
+whole year. While this would take considerable disk space it would
+also take a lot of time to analyze the data when you wanted to create
+a graph covering the whole year. \fBRRDtool\fR offers a solution to this
+problem through its data consolidation feature. When setting up an
+Round Robin Database (\fB\s-1RRD\s0\fR), you can define at which interval this
+consolidation should occur, and what consolidation function (\fB\s-1CF\s0\fR)
+(average, minimum, maximum, total, last) should be used to build the
+consolidated values (see rrdcreate). You can define any number of
+different consolidation setups within one \fB\s-1RRD\s0\fR. They will all be
+maintained on the fly when new data is loaded into the \fB\s-1RRD\s0\fR.
+.IP "Round Robin Archives" 8
+.IX Item "Round Robin Archives"
+Data values of the same consolidation setup are stored into Round
+Robin Archives (\fB\s-1RRA\s0\fR). This is a very efficient manner to store data
+for a certain amount of time, while using a known and constant amount
+of storage space.
+.Sp
+It works like this: If you want to store 1'000 values in 5 minute
+interval, \fBRRDtool\fR will allocate space for 1'000 data values and a
+header area. In the header it will store a pointer telling which slots
+(value) in the storage area was last written to. New values are
+written to the Round Robin Archive in, you guessed it, a round robin
+manner. This automatically limits the history to the last 1'000 values
+(in our example). Because you can define several \fB\s-1RRA\s0\fRs within a
+single \fB\s-1RRD\s0\fR, you can setup another one, for storing 750 data values
+at a 2 hour interval, for example, and thus keep a log for the last
+two months at a lower resolution.
+.Sp
+The use of \fB\s-1RRA\s0\fRs guarantees that the \fB\s-1RRD\s0\fR does not grow over
+time and that old data is automatically eliminated. By using the
+consolidation feature, you can still keep data for a very long time,
+while gradually reducing the resolution of the data along the time
+axis.
+.Sp
+Using different consolidation functions (\fB\s-1CF\s0\fR) allows you to store
+exactly the type of information that actually interests you: the maximum
+one minute traffic on the \s-1LAN\s0, the minimum temperature of your wine cellar,
+the total minutes of down time, etc.
+.IP "Unknown Data" 8
+.IX Item "Unknown Data"
+As mentioned earlier, the \fB\s-1RRD\s0\fR stores data at a constant
+interval. Sometimes it may happen that no new data is available when a
+value has to be written to the \fB\s-1RRD\s0\fR. Data acquisition may not be
+possible for one reason or other. With \fBRRDtool\fR you can handle these
+situations by storing an \fI*UNKNOWN*\fR value into the database. The
+value '\fI*UNKNOWN*\fR' is supported through all the functions of the
+tool. When consolidating a data set, the amount of \fI*UNKNOWN*\fR data
+values is accounted for and when a new consolidated value is ready to
+be written to its Round Robin Archive (\fB\s-1RRA\s0\fR), a validity check is
+performed to make sure that the percentage of unknown values in the
+data point is above a configurable level. If not, an \fI*UNKNOWN*\fR value
+will be written to the \fB\s-1RRA\s0\fR.
+.IP "Graphing" 8
+.IX Item "Graphing"
+\&\fBRRDtool\fR allows you to generate reports in numerical and
+graphical form based on the data stored in one or several
+\&\fB\s-1RRD\s0\fRs. The graphing feature is fully configurable. Size, color and
+contents of the graph can be defined freely. Check rrdgraph
+for more information on this.
+.IP "Aberrant Behavior Detection" 8
+.IX Item "Aberrant Behavior Detection"
+by Jake Brutlag
+.Sp
+\&\fBRRDtool\fR provides the building blocks for near real-time aberrant
+behavior detection. These components include:
+.RS 8
+.IP "*" 4
+An algorithm for predicting the value of a time series one time step
+into the future.
+.IP "*" 4
+A measure of deviation between predicted and observed values.
+.IP "*" 4
+A mechanism to decide if and when an observed value or sequence of
+observed values is \fItoo deviant\fR from the predicted value(s).
+.RE
+.RS 8
+.Sp
+Here is a brief explanation of these components:
+.Sp
+The Holt-Winters time series forecasting algorithm is an on-line (or
+incremental) algorithm that adaptively predicts future observations in
+a time series. Its forecast is the sum of three components: a baseline
+(or intercept), a linear trend over time (or slope), and a seasonal
+coefficient (a periodic effect, such as a daily cycle). There is one
+seasonal coefficient for each time point in the period (cycle). After
+a value is observed, each of these components is updated via
+exponential smoothing. This means that the algorithm \*(L"learns\*(R" from
+past values and uses them to predict the future. The rate of
+adaptation is governed by 3 parameters, alpha (intercept), beta
+(slope), and gamma (seasonal). The prediction can also be viewed as a
+smoothed value for the time series.
+.Sp
+The measure of deviation is a seasonal weighted absolute
+deviation. The term \fIseasonal\fR means deviation is measured separately
+for each time point in the seasonal cycle. As with Holt-Winters
+forecasting, deviation is predicted using the measure computed from
+past values (but only at that point in the seasonal cycle). After the
+value is observed, the algorithm learns from the observed value via
+exponential smoothing. Confidence bands for the observed time series
+are generated by scaling the sequence of predicted deviation values
+(we usually think of the sequence as a continuous line rather than a
+set of discrete points).
+.Sp
+Aberrant behavior (a potential failure) is reported whenever the
+number of times the observed value violates the confidence bands meets
+or exceeds a specified threshold within a specified temporal window
+(e.g. 5 violations during the past 45 minutes with a value observed
+every 5 minutes).
+.Sp
+This functionality is embedded in a set of related \fBRRAs\fR. In
+particular, a \s-1FAILURES\s0 \fB\s-1RRA\s0\fR logs potential failures. With these data
+you could, for example, use a front-end application to \fBRRDtool\fR to
+initiate real-time alerts.
+.Sp
+For a detailed description on how to set this up, see rrdcreate.
+.RE
+.Sh "\s-1REMOTE\s0 \s-1CONTROL\s0"
+.IX Subsection "REMOTE CONTROL"
+When you start \fBRRDtool\fR with the command line option '\fB\-\fR' it waits
+for input via standard input (\s-1STDIN\s0). With this feature you can
+improve performance by attaching \fBRRDtool\fR to another process (\s-1MRTG\s0
+is one example) through a set of pipes. Over these pipes \fBRRDtool\fR
+accepts the same arguments as on the command line and some special
+commands like \fBquit, cd, mkdir\fR and \fBls\fR. For detailed help on the
+server commands type:
+.PP
+.Vb 1
+\&   rrdtool help cd|mkdir|pwd|ls|quit
+.Ve
+.PP
+When a command is completed, RRDtool will print the string  '\f(CW\*(C`OK\*(C'\fR',
+followed by timing information of the form \fBu:\fR\fIusertime\fR
+\&\fBs:\fR\fIsystemtime\fR. Both values are the running totals of seconds since
+RRDtool was started. If an error occurs, a line of the form '\f(CW\*(C`ERROR:\*(C'\fR
+\&\fIDescription of error\fR' will be printed instead. \fBRRDtool\fR will not abort,
+unless something realy serious happens. If
+a \fBworkdir\fR is specified and the \s-1UID\s0 is 0, RRDtool will do a chroot to that
+workdir. If the \s-1UID\s0 is not 0, RRDtool only changes the current directory to
+\&\fBworkdir\fR.
+.Sh "\s-1RRD\s0 Server"
+.IX Subsection "RRD Server"
+If you want to create a RRD\-Server, you must choose a \s-1TCP/IP\s0 Service
+number and add them to \fI/etc/services\fR like this:
+.PP
+.Vb 1
+\& rrdsrv      13900/tcp                       # RRD server
+.Ve
+.PP
+Attention: the \s-1TCP\s0 port 13900 isn't officially registered for
+rrdsrv. You can use any unused port in your services file, but the
+server and the client system must use the same port, of course.
+.PP
+With this configuration you can add RRDtool as meta-server to
+\&\fI/etc/inetd.conf\fR. For example:
+.PP
+.Vb 1
+\& rrdsrv stream tcp nowait root /opt/rrd/bin/rrdtool rrdtool \- /var/rrd
+.Ve
+.PP
+Don't forget to create the database directory /var/rrd and
+reinitialize your inetd.
+.PP
+If all was setup correctly, you can access the server with perl
+sockets, tools like netcat, or in a quick interactive test by using
+\&'telnet localhost rrdsrv'.
+.PP
+\&\fB\s-1NOTE:\s0\fR that there is no authentication with this feature! Do not setup
+such a port unless you are sure what you are doing.

+<p><strong>RRDtool</strong> provides the building blocks for near real-time aberrant
+behavior detection. These components include:</p>
+</dd>
+<ul>
+<li>
+<p>An algorithm for predicting the value of a time series one time step
+into the future.</p>
+</li>
+<li>
+<p>A measure of deviation between predicted and observed values.</p>
+</li>
+<li>
+<p>A mechanism to decide if and when an observed value or sequence of
+observed values is <em>too deviant</em> from the predicted value(s).</p>
+</li>
+</ul>
+<p>Here is a brief explanation of these components:</p>
+<p>The Holt-Winters time series forecasting algorithm is an on-line (or
+incremental) algorithm that adaptively predicts future observations in
+a time series. Its forecast is the sum of three components: a baseline
+(or intercept), a linear trend over time (or slope), and a seasonal
+coefficient (a periodic effect, such as a daily cycle). There is one
+seasonal coefficient for each time point in the period (cycle). After
+a value is observed, each of these components is updated via
+exponential smoothing. This means that the algorithm ``learns'' from
+past values and uses them to predict the future. The rate of
+adaptation is governed by 3 parameters, alpha (intercept), beta
+(slope), and gamma (seasonal). The prediction can also be viewed as a
+smoothed value for the time series.</p>
+<p>The measure of deviation is a seasonal weighted absolute
+deviation. The term <em>seasonal</em> means deviation is measured separately
+for each time point in the seasonal cycle. As with Holt-Winters
+forecasting, deviation is predicted using the measure computed from
+past values (but only at that point in the seasonal cycle). After the
+value is observed, the algorithm learns from the observed value via
+exponential smoothing. Confidence bands for the observed time series
+are generated by scaling the sequence of predicted deviation values
+(we usually think of the sequence as a continuous line rather than a
+set of discrete points).</p>
+<p>Aberrant behavior (a potential failure) is reported whenever the
+number of times the observed value violates the confidence bands meets
+or exceeds a specified threshold within a specified temporal window
+(e.g. 5 violations during the past 45 minutes with a value observed
+every 5 minutes).</p>
+<p>This functionality is embedded in a set of related <strong>RRAs</strong>. In
+particular, a FAILURES <strong>RRA</strong> logs potential failures. With these data
+you could, for example, use a front-end application to <strong>RRDtool</strong> to
+initiate real-time alerts.</p>
+<p>For a detailed description on how to set this up, see <a href="././rrdcreate.html">the rrdcreate manpage</a>.</p>

+<p>
+</p>
+<h2><a name="remote_control">REMOTE CONTROL</a></h2>
+<p>When you start <strong>RRDtool</strong> with the command line option '<strong>-</strong>' it waits
+for input via standard input (STDIN). With this feature you can
+improve performance by attaching <strong>RRDtool</strong> to another process (MRTG
+is one example) through a set of pipes. Over these pipes <strong>RRDtool</strong>
+accepts the same arguments as on the command line and some special
+commands like <strong>quit, cd, mkdir</strong> and <strong>ls</strong>. For detailed help on the
+server commands type:</p>
+<pre>
+   rrdtool help cd|mkdir|pwd|ls|quit</pre>
+<p>When a command is completed, RRDtool will print the string  '<code>OK</code>',
+followed by timing information of the form <strong>u:</strong><em>usertime</em>
+<strong>s:</strong><em>systemtime</em>. Both values are the running totals of seconds since
+RRDtool was started. If an error occurs, a line of the form '<code>ERROR:</code>
+<em>Description of error</em>' will be printed instead. <strong>RRDtool</strong> will not abort,
+unless something realy serious happens. If
+a <strong>workdir</strong> is specified and the UID is 0, RRDtool will do a chroot to that
+workdir. If the UID is not 0, RRDtool only changes the current directory to
+<strong>workdir</strong>.</p>

+<h2><a name="rrd_server">RRD Server</a></h2>
+<p>If you want to create a RRD-Server, you must choose a TCP/IP Service

+<p>Attention: the TCP port 13900 isn't officially registered for
+rrdsrv. You can use any unused port in your services file, but the
+server and the client system must use the same port, of course.</p>
+<p>With this configuration you can add RRDtool as meta-server to
+<em>/etc/inetd.conf</em>. For example:</p>
+<pre>
+ rrdsrv stream tcp nowait root /opt/rrd/bin/rrdtool rrdtool - /var/rrd</pre>
+<p>Don't forget to create the database directory /var/rrd and

+
+rrdtool - Round Robin Database Tool
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<-> [workdir]| I<function>
+
+=head1 DESCRIPTION
+
+=head2 OVERVIEW
+
+It is pretty easy to gather status information from all sorts of
+things, ranging from the temperature in your office to the number of
+octets which have passed through the FDDI interface of your
+router. But it is not so trivial to store this data in an efficient and
+systematic manner. This is where B<RRDtool> comes in handy. It lets you
+I<log and analyze> the data you gather from all kinds of data-sources
+(B<DS>). The data analysis part of RRDtool is based on the ability to
+quickly generate graphical representations of the data values
+collected over a definable time period.
+
+In this man page you will find general information on the design and
+functionality of the Round Robin Database Tool (RRDtool). For a more
+detailed description of how to use the individual functions of
+B<RRDtool> check the corresponding man page.
+
+For an introduction to the usage of RRDtool make sure you consult the
+L<rrdtutorial>.
+
+=head2 FUNCTIONS
+
+While the man pages talk of command line switches you have to set in
+order to make B<RRDtool> work it is important to note that
+B<RRDtool> can be remotely controlled through a set of pipes. This
+saves a considerable amount of startup time when you plan to make
+B<RRDtool> do a lot of things quickly. Check the section on L<"Remote
+Control"> further down. There is also a number of language bindings
+for RRDtool which allow you to use it directly from perl, python, tcl,
+php, etc.

+
+With this configuration you can add RRDtool as meta-server to

+       It is pretty easy to gather status information from all sorts of
+       things, ranging from the temperature in your office to the number of
+       octets which have passed through the FDDI interface of your router. But
+       it is not so trivial to store this data in an efficient and systematic
+       manner. This is where R\bRR\bRD\bDt\bto\boo\bol\bl comes in handy. It lets you _\bl_\bo_\bg _\ba_\bn_\bd _\ba_\bn_\ba_\b-
+       _\bl_\by_\bz_\be the data you gather from all kinds of data-sources (D\bDS\bS). The data
+       analysis part of RRDtool is based on the ability to quickly generate
+       graphical representations of the data values collected over a definable
+       time period.
+
+       In this man page you will find general information on the design and
+       functionality of the Round Robin Database Tool (RRDtool). For a more
+       detailed description of how to use the individual functions of R\bRR\bRD\bDt\bto\boo\bol\bl
+       check the corresponding man page.
+
+       For an introduction to the usage of RRDtool make sure you consult the
+       rrdtutorial.

+       While the man pages talk of command line switches you have to set in
+       order to make R\bRR\bRD\bDt\bto\boo\bol\bl work it is important to note that R\bRR\bRD\bDt\bto\boo\bol\bl can be
+       remotely controlled through a set of pipes. This saves a considerable
+       amount of startup time when you plan to make R\bRR\bRD\bDt\bto\boo\bol\bl do a lot of things
+       quickly. Check the section on "Remote Control" further down. There is
+       also a number of language bindings for RRDtool which allow you to use
+       it directly from perl, python, tcl, php, etc.

+
+       Data Acquisition
+               When monitoring the state of a system, it is convenient to have
+               the data available at a constant time interval. Unfortunately,
+               you may not always be able to fetch data at exactly the time
+               you want to. Therefore R\bRR\bRD\bDt\bto\boo\bol\bl lets you update the logfile at
+               any time you want. It will automatically interpolate the value
+               of the data-source (D\bDS\bS) at the latest official time-slot
+               (intervall) and write this interpolated value to the log. The
+               original value you have supplied is stored as well and is also
+               taken into account when interpolating the next log entry.
+
+       Consolidation
+               You may log data at a 1 minute interval, but you might also be
+               interested to know the development of the data over the last
+               year. You could do this by simply storing the data in 1 minute
+               intervals for the whole year. While this would take consider-
+               able disk space it would also take a lot of time to analyze the
+               data when you wanted to create a graph covering the whole year.
+               R\bRR\bRD\bDt\bto\boo\bol\bl offers a solution to this problem through its data con-
+               solidation feature. When setting up an Round Robin Database
+               (R\bRR\bRD\bD), you can define at which interval this consolidation
+               should occur, and what consolidation function (C\bCF\bF) (average,
+               minimum, maximum, total, last) should be used to build the con-
+               solidated values (see rrdcreate). You can define any number of
+               different consolidation setups within one R\bRR\bRD\bD. They will all be
+               maintained on the fly when new data is loaded into the R\bRR\bRD\bD.
+
+       Round Robin Archives
+               Data values of the same consolidation setup are stored into
+               Round Robin Archives (R\bRR\bRA\bA). This is a very efficient manner to
+               store data for a certain amount of time, while using a known
+               and constant amount of storage space.
+
+               It works like this: If you want to store 1'000 values in 5
+               minute interval, R\bRR\bRD\bDt\bto\boo\bol\bl will allocate space for 1'000 data
+               values and a header area. In the header it will store a pointer
+               telling which slots (value) in the storage area was last writ-
+               ten to. New values are written to the Round Robin Archive in,
+               you guessed it, a round robin manner. This automatically limits
+               the history to the last 1'000 values (in our example). Because
+               you can define several R\bRR\bRA\bAs within a single R\bRR\bRD\bD, you can setup
+               another one, for storing 750 data values at a 2 hour interval,
+               for example, and thus keep a log for the last two months at a
+               lower resolution.
+
+               The use of R\bRR\bRA\bAs guarantees that the R\bRR\bRD\bD does not grow over time
+               and that old data is automatically eliminated. By using the
+               consolidation feature, you can still keep data for a very long
+               time, while gradually reducing the resolution of the data along
+               the time axis.
+
+               Using different consolidation functions (C\bCF\bF) allows you to
+               store exactly the type of information that actually interests
+               you: the maximum one minute traffic on the LAN, the minimum
+               temperature of your wine cellar, the total minutes of down
+               time, etc.
+
+       Unknown Data
+               As mentioned earlier, the R\bRR\bRD\bD stores data at a constant inter-
+               val. Sometimes it may happen that no new data is available when
+               a value has to be written to the R\bRR\bRD\bD. Data acquisition may not
+               be possible for one reason or other. With R\bRR\bRD\bDt\bto\boo\bol\bl you can han-
+               dle these situations by storing an _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* value into the
+               database. The value '_\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b*' is supported through all the
+               functions of the tool. When consolidating a data set, the
+               amount of _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* data values is accounted for and when a new
+               consolidated value is ready to be written to its Round Robin
+               Archive (R\bRR\bRA\bA), a validity check is performed to make sure that
+               the percentage of unknown values in the data point is above a
+               configurable level. If not, an _\b*_\bU_\bN_\bK_\bN_\bO_\bW_\bN_\b* value will be written
+               to the R\bRR\bRA\bA.
+
+       Graphing
+               R\bRR\bRD\bDt\bto\boo\bol\bl allows you to generate reports in numerical and graphi-
+               cal form based on the data stored in one or several R\bRR\bRD\bDs. The
+               graphing feature is fully configurable. Size, color and con-
+               tents of the graph can be defined freely. Check rrdgraph for
+               more information on this.
+
+       Aberrant Behavior Detection
+               by Jake Brutlag
+
+               R\bRR\bRD\bDt\bto\boo\bol\bl provides the building blocks for near real-time aber-
+               rant behavior detection. These components include:
+
+               *   An algorithm for predicting the value of a time series one
+                   time step into the future.
+
+               *   A measure of deviation between predicted and observed val-
+                   ues.
+
+               *   A mechanism to decide if and when an observed value or
+                   sequence of observed values is _\bt_\bo_\bo _\bd_\be_\bv_\bi_\ba_\bn_\bt from the pre-
+                   dicted value(s).
+
+               Here is a brief explanation of these components:
+
+               The Holt-Winters time series forecasting algorithm is an on-
+               line (or incremental) algorithm that adaptively predicts future
+               observations in a time series. Its forecast is the sum of three
+               components: a baseline (or intercept), a linear trend over time
+               (or slope), and a seasonal coefficient (a periodic effect, such
+               as a daily cycle). There is one seasonal coefficient for each
+               time point in the period (cycle). After a value is observed,
+               each of these components is updated via exponential smoothing.
+               This means that the algorithm "learns" from past values and
+               uses them to predict the future. The rate of adaptation is gov-
+               erned by 3 parameters, alpha (intercept), beta (slope), and
+               gamma (seasonal). The prediction can also be viewed as a
+               smoothed value for the time series.
+
+               The measure of deviation is a seasonal weighted absolute devia-
+               tion. The term _\bs_\be_\ba_\bs_\bo_\bn_\ba_\bl means deviation is measured separately
+               for each time point in the seasonal cycle. As with Holt-Winters
+               forecasting, deviation is predicted using the measure computed
+               from past values (but only at that point in the seasonal
+               cycle). After the value is observed, the algorithm learns from
+               the observed value via exponential smoothing. Confidence bands
+               for the observed time series are generated by scaling the
+               sequence of predicted deviation values (we usually think of the
+               sequence as a continuous line rather than a set of discrete
+               points).
+
+               Aberrant behavior (a potential failure) is reported whenever
+               the number of times the observed value violates the confidence
+               bands meets or exceeds a specified threshold within a specified
+               temporal window (e.g. 5 violations during the past 45 minutes
+               with a value observed every 5 minutes).
+
+               This functionality is embedded in a set of related R\bRR\bRA\bAs\bs. In
+               particular, a FAILURES R\bRR\bRA\bA logs potential failures. With these
+               data you could, for example, use a front-end application to
+               R\bRR\bRD\bDt\bto\boo\bol\bl to initiate real-time alerts.
+
+               For a detailed description on how to set this up, see rrdcre-
+               ate.
+
+       R\bRE\bEM\bMO\bOT\bTE\bE C\bCO\bON\bNT\bTR\bRO\bOL\bL
+
+       When you start R\bRR\bRD\bDt\bto\boo\bol\bl with the command line option '-\b-' it waits for
+       input via standard input (STDIN). With this feature you can improve
+       performance by attaching R\bRR\bRD\bDt\bto\boo\bol\bl to another process (MRTG is one exam-
+       ple) through a set of pipes. Over these pipes R\bRR\bRD\bDt\bto\boo\bol\bl accepts the same
+       arguments as on the command line and some special commands like q\bqu\bui\bit\bt,\b,
+       c\bcd\bd,\b, m\bmk\bkd\bdi\bir\br and l\bls\bs. For detailed help on the server commands type:
+
+          rrdtool help cd|mkdir|pwd|ls|quit
+
+       When a command is completed, RRDtool will print the string  '"OK"',
+       followed by timing information of the form u\bu:\b:_\bu_\bs_\be_\br_\bt_\bi_\bm_\be s\bs:\b:_\bs_\by_\bs_\bt_\be_\bm_\bt_\bi_\bm_\be.
+       Both values are the running totals of seconds since RRDtool was
+       started. If an error occurs, a line of the form '"ERROR:" _\bD_\be_\bs_\bc_\br_\bi_\bp_\bt_\bi_\bo_\bn
+       _\bo_\bf _\be_\br_\br_\bo_\br' will be printed instead. R\bRR\bRD\bDt\bto\boo\bol\bl will not abort, unless some-
+       thing realy serious happens. If a w\bwo\bor\brk\bkd\bdi\bir\br is specified and the UID is
+       0, RRDtool will do a chroot to that workdir. If the UID is not 0, RRD-
+       tool only changes the current directory to w\bwo\bor\brk\bkd\bdi\bir\br.
+
+       R\bRR\bRD\bD S\bSe\ber\brv\bve\ber\br
+
+       If you want to create a RRD-Server, you must choose a TCP/IP Service
+       number and add them to _\b/_\be_\bt_\bc_\b/_\bs_\be_\br_\bv_\bi_\bc_\be_\bs like this:
+
+        rrdsrv      13900/tcp                       # RRD server
+
+       Attention: the TCP port 13900 isn't officially registered for rrdsrv.
+       You can use any unused port in your services file, but the server and
+       the client system must use the same port, of course.
+
+       With this configuration you can add RRDtool as meta-server to
+       _\b/_\be_\bt_\bc_\b/_\bi_\bn_\be_\bt_\bd_\b._\bc_\bo_\bn_\bf. For example:
+
+        rrdsrv stream tcp nowait root /opt/rrd/bin/rrdtool rrdtool - /var/rrd
+
+       Don't forget to create the database directory /var/rrd and reinitialize
+       your inetd.
+
+       If all was setup correctly, you can access the server with perl sock-
+       ets, tools like netcat, or in a quick interactive test by using 'telnet
+       localhost rrdsrv'.
+
+       N\bNO\bOT\bTE\bE:\b: that there is no authentication with this feature! Do not setup
+       such a port unless you are sure what you are doing.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The tune option allows you to alter some of the basic configuration
+values stored in the header area of a Round Robin Database (\fB\s-1RRD\s0\fR).
+.PP
+One application of the \fBtune\fR function is to relax the
+validation rules on an \fB\s-1RRD\s0\fR. This allows to fill a new \fB\s-1RRD\s0\fR with
+data available in larger intervals than what you would normally want
+to permit. Be very careful with tune operations for \s-1COMPUTE\s0 data sources.
+Setting the \fImin\fR, \fImax\fR, and  \fIheartbeat\fR for a \s-1COMPUTE\s0 data source
+without changing the data source type to a non-COMPUTE \fB\s-1DST\s0\fR \s-1WILL\s0 corrupt
+the data source header in the \fB\s-1RRD\s0\fR.
+.PP
+A second application of the \fBtune\fR function is to set or alter parameters
+used by the specialized function \fBRRAs\fR for aberrant behavior detection.
+.IP "\fIfilename\fR" 8
+.IX Item "filename"
+The name of the \fB\s-1RRD\s0\fR you want to tune.
+.IP "\fB\-\-heartbeat\fR|\fB\-h\fR\ \fIds-name\fR:\fIheartbeat\fR" 8
+.IX Item "--heartbeat|-hds-name:heartbeat"
+modify the \fIheartbeat\fR of a data source. By setting this to a high
+value the \s-1RRD\s0 will accept things like one value per day.
+.IP "\fB\-\-minimum\fR|\fB\-i\fR\ \fIds-name\fR:\fImin\fR" 8
+.IX Item "--minimum|-ids-name:min"
+alter the minimum value acceptable as input from the data source.
+Setting \fImin\fR to 'U' will disable this limit.
+.IP "\fB\-\-maximum\fR|\fB\-a\fR\ \fIds-name\fR:\fImax\fR" 8
+.IX Item "--maximum|-ads-name:max"
+alter the maximum value acceptable as input from the data source.
+Setting \fImax\fR to 'U' will disable this limit.
+.IP "\fB\-\-data\-source\-type\fR|\fB\-d\fR\ \fIds-name\fR:\fI\s-1DST\s0\fR" 8
+.IX Item "--data-source-type|-dds-name:DST"

+.IX Item "--data-source-rename|-rold-name:new-name"

+.IP "\fB\-\-deltapos\fR\ \fIscale-value\fR" 8
+.IX Item "--deltaposscale-value"
+Alter the deviation scaling factor for the upper bound of the
+confidence band used internally to calculate violations for the
+\&\s-1FAILURES\s0 \fB\s-1RRA\s0\fR. The default value is 2. Note that this parameter is
+not related to graphing confidence bounds which must be specified as a
+\&\s-1CDEF\s0 argument to generate a graph with confidence bounds. The graph
+scale factor need not to agree with the value used internally by the
+\&\s-1FAILURES\s0 \fB\s-1RRA\s0\fR.
+.IP "\fB\-\-deltaneg\fR\ \fIscale-value\fR" 8
+.IX Item "--deltanegscale-value"
+Alter the deviation scaling factor for the lower bound of the confidence band
+used internally to calculate violations for the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR. The default
+value is 2. As with \fB\-\-deltapos\fR, this argument is unrelated to the scale
+factor chosen when graphing confidence bounds.
+.IP "\fB\-\-failure\-threshold\fR\ \fIfailure-threshold\fR" 8
+.IX Item "--failure-thresholdfailure-threshold"
+Alter the number of confidence bound violations that constitute a failure for
+purposes of the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR. This must be an integer less than or equal to
+the window length of the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR. This restriction is not verified by
+the tune option, so one can reset failure-threshold and window-length
+simultaneously. Setting this option will reset the count of violations to 0.
+.IP "\fB\-\-window\-length\fR\ \fIwindow-length\fR" 8
+.IX Item "--window-lengthwindow-length"
+Alter the number of time points in the temporal window for determining
+failures. This must be an integer greater than or equal to the window
+length of the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR and less than or equal to 28. Setting
+this option will reset the count of violations to 0.
+.IP "\fB\-\-alpha\fR\ \fIadaption-parameter\fR" 8
+.IX Item "--alphaadaption-parameter"
+Alter the intercept adaptation parameter for the Holt-Winters
+forecasting algorithm. This parameter must be between 0 and 1.
+.IP "\fB\-\-beta\fR\ \fIadaption-parameter\fR" 8
+.IX Item "--betaadaption-parameter"
+Alter the slope adaptation parameter for the Holt-Winters forecasting
+algorithm. This parameter must be between 0 and 1.
+.IP "\fB\-\-gamma\fR\ \fIadaption-parameter\fR" 8
+.IX Item "--gammaadaption-parameter"
+Alter the seasonal coefficient adaptation parameter for the \s-1SEASONAL\s0
+\&\fB\s-1RRA\s0\fR. This parameter must be between 0 and 1.
+.IP "\fB\-\-gamma\-deviation\fR\ \fIadaption-parameter\fR" 8
+.IX Item "--gamma-deviationadaption-parameter"
+Alter the seasonal deviation adaptation parameter for the \s-1DEVSEASONAL\s0
+\&\fB\s-1RRA\s0\fR. This parameter must be between 0 and 1.
+.IP "\fB\-\-aberrant\-reset\fR\ \fIds-name\fR" 8
+.IX Item "--aberrant-resetds-name"
+This option causes the aberrant behavior detection algorithm to reset
+for the specified data source; that is, forget all it is has learnt so far.
+Specifically, for the \s-1HWPREDICT\s0 \fB\s-1RRA\s0\fR, it sets the intercept and slope
+coefficients to unknown. For the \s-1SEASONAL\s0 \fB\s-1RRA\s0\fR, it sets all seasonal
+coefficients to unknown. For the \s-1DEVSEASONAL\s0 \fB\s-1RRA\s0\fR, it sets all seasonal
+deviation coefficients to unknown. For the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR, it erases
+the violation history. Note that reset does not erase past predictions
+(the values of the \s-1HWPREDICT\s0 \fB\s-1RRA\s0\fR), predicted deviations (the values of the
+\&\s-1DEVPREDICT\s0 \fB\s-1RRA\s0\fR), or failure history (the values of the \s-1FAILURES\s0 \fB\s-1RRA\s0\fR).
+This option will function even if not all the listed \fBRRAs\fR are present.
+.Sp
+Due to the implementation of this option, there is an indirect impact on
+other data sources in the \s-1RRD\s0. A smoothing algorithm is applied to
+\&\s-1SEASONAL\s0 and \s-1DEVSEASONAL\s0 values on a periodic basis. During bootstrap
+initialization this smoothing is deferred. For efficiency, the implementation
+of smoothing is not data source specific. This means that utilizing
+reset for one data source will delay running the smoothing algorithm
+for all data sources in the file. This is unlikely to have serious
+consequences, unless the data being collected for the non-reset data sources
+is unusually volatile during the reinitialization period of the reset
+data source.
+.Sp
+Use of this tuning option is advised when the behavior of the data source
+time series changes in a drastic and permanent manner.

+
+This option causes the aberrant behavior detection algorithm to reset

+Specifically, for the HWPREDICT B<RRA>, it sets the intercept and slope
+coefficients to unknown. For the SEASONAL B<RRA>, it sets all seasonal
+coefficients to unknown. For the DEVSEASONAL B<RRA>, it sets all seasonal
+deviation coefficients to unknown. For the FAILURES B<RRA>, it erases
+the violation history. Note that reset does not erase past predictions
+(the values of the HWPREDICT B<RRA>), predicted deviations (the values of the
+DEVPREDICT B<RRA>), or failure history (the values of the FAILURES B<RRA>).
+This option will function even if not all the listed B<RRAs> are present.
+
+Due to the implementation of this option, there is an indirect impact on
+other data sources in the RRD. A smoothing algorithm is applied to
+SEASONAL and DEVSEASONAL values on a periodic basis. During bootstrap
+initialization this smoothing is deferred. For efficiency, the implementation
+of smoothing is not data source specific. This means that utilizing
+reset for one data source will delay running the smoothing algorithm
+for all data sources in the file. This is unlikely to have serious
+consequences, unless the data being collected for the non-reset data sources
+is unusually volatile during the reinitialization period of the reset
+data source.
+
+Use of this tuning option is advised when the behavior of the data source
+time series changes in a drastic and permanent manner.

+
+Set the minimum required heartbeat for data sources 'in', 'out'
+and 'through' to 10'000 seconds which is a little over one day in data.rrd.
+This would allow to feed old data from MRTG-2.0 right into

+C<rrdtool tune monitor.rrd --window-length 5 --failure-threshold 3>
+
+If the FAILURES B<RRA> is implicitly created, the default

+command now defines a failure as 3 or more violations in a temporal
+window of 5 time points.

+       The tune option allows you to alter some of the basic configuration
+       values stored in the header area of a Round Robin Database (R\bRR\bRD\bD).
+
+       One application of the t\btu\bun\bne\be function is to relax the validation rules
+       on an R\bRR\bRD\bD. This allows to fill a new R\bRR\bRD\bD with data available in larger
+       intervals than what you would normally want to permit. Be very careful
+       with tune operations for COMPUTE data sources.  Setting the _\bm_\bi_\bn, _\bm_\ba_\bx,
+       and  _\bh_\be_\ba_\br_\bt_\bb_\be_\ba_\bt for a COMPUTE data source without changing the data
+       source type to a non-COMPUTE D\bDS\bST\bT WILL corrupt the data source header in
+       the R\bRR\bRD\bD.
+
+       A second application of the t\btu\bun\bne\be function is to set or alter parameters
+       used by the specialized function R\bRR\bRA\bAs\bs for aberrant behavior detection.

+               This option causes the aberrant behavior detection algorithm to
+               reset for the specified data source; that is, forget all it is
+               has learnt so far.  Specifically, for the HWPREDICT R\bRR\bRA\bA, it
+               sets the intercept and slope coefficients to unknown. For the
+               SEASONAL R\bRR\bRA\bA, it sets all seasonal coefficients to unknown. For
+               the DEVSEASONAL R\bRR\bRA\bA, it sets all seasonal deviation coeffi-
+               cients to unknown. For the FAILURES R\bRR\bRA\bA, it erases the viola-
+               tion history. Note that reset does not erase past predictions
+               (the values of the HWPREDICT R\bRR\bRA\bA), predicted deviations (the
+               values of the DEVPREDICT R\bRR\bRA\bA), or failure history (the values
+               of the FAILURES R\bRR\bRA\bA).  This option will function even if not
+               all the listed R\bRR\bRA\bAs\bs are present.
+
+               Due to the implementation of this option, there is an indirect
+               impact on other data sources in the RRD. A smoothing algorithm
+               is applied to SEASONAL and DEVSEASONAL values on a periodic
+               basis. During bootstrap initialization this smoothing is
+               deferred. For efficiency, the implementation of smoothing is
+               not data source specific. This means that utilizing reset for
+               one data source will delay running the smoothing algorithm for
+               all data sources in the file. This is unlikely to have serious
+               consequences, unless the data being collected for the non-reset
+               data sources is unusually volatile during the reinitialization
+               period of the reset data source.
+
+               Use of this tuning option is advised when the behavior of the
+               data source time series changes in a drastic and permanent man-
+               ner.

+
+       Set the minimum required heartbeat for data sources 'in', 'out' and
+       'through' to 10'000 seconds which is a little over one day in data.rrd.

+rrdtutorial \- Alex van den Bogaerdt's RRDtool tutorial
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+RRDtool is written by Tobias Oetiker <tobi@oetiker.ch> with
+contributions from many people all around the world. This document is
+written by Alex van den Bogaerdt <alex@ergens.op.het.net> to help you
+understand what RRDtool is and what it can do for you.
+.PP
+The documentation provided with RRDtool can be too technical for some
+people. This tutorial is here to help you understand the basics of
+RRDtool. It should prepare you to read the documentation yourself.
+It also explains the general things about statistics with a focus on
+networking.
+.SH "TUTORIAL"
+.IX Header "TUTORIAL"
+.Sh "Important"
+.IX Subsection "Important"
+Please don't skip ahead in this document!  The first part of this
+document explains the basics and may be boring.  But if you don't
+understand the basics, the examples will not be as meaningful to you.
+.Sh "What is RRDtool?"
+.IX Subsection "What is RRDtool?"
+RRDtool refers to Round Robin Database tool.
+Round robin is a technique that works with a fixed amount of data, and a
+pointer to the current element. Think of a circle with some dots plotted
+on the edge \*(-- these dots are the places where data can be stored. Draw an
+arrow from the center of the circle to one of the dots \*(-- this is the pointer.
+When the current data is read or written, the pointer moves to the next
+element. As we are on a circle there is neither a beginning nor an end, you can
+go on and on and on. After a while, all the available places will be used and
+the process automatically reuses old locations. This way, the dataset
+will not grow in size and therefore requires no maintenance.
+RRDtool works with with Round Robin Databases (RRDs). It stores and retrieves
+data from them.
+.Sh "What data can be put into an \s-1RRD\s0?"
+.IX Subsection "What data can be put into an RRD?"
+You name it, it will probably fit as long as it is some sort of time-series
+data. This means you have to be able to measure some value at several points in time and
+provide this information to RRDtool. If you can do this, RRDtool will be
+able to store it. The values must be numerical but don't have to be
+integers, as is the case with \s-1MRTG\s0 (the next section will give more details
+on this more specialized application).
+.PP
+Many examples below talk about \s-1SNMP\s0 which is an acronym for Simple Network
+Management Protocol. \*(L"Simple\*(R" refers to the protocol \*(-- it does not
+mean it is simple to manage or monitor a network. After working your
+way through this document, you should know enough to be able to
+understand what people are talking about. For now, just realize that
+\&\s-1SNMP\s0 can be used to query devices for the values of counters they keep. It
+is the value from those counters that we want to store in the \s-1RRD\s0.
+.Sh "What can I do with this tool?"
+.IX Subsection "What can I do with this tool?"
+RRDtool originated from \s-1MRTG\s0 (Multi Router Traffic Grapher). \s-1MRTG\s0
+started as a tiny little script for graphing the use of a university's
+connection to the Internet. \s-1MRTG\s0 was later (ab\-)used as a tool for
+graphing other data sources including temperature, speed, voltage,
+number of printouts and the like.
+.PP
+Most likely you will start to use RRDtool to store and process data
+collected via \s-1SNMP\s0. The data will most likely be bytes (or bits)
+transfered from and to a network or a computer.  But it can also be
+used to display tidal waves, solar radiation, power consumption,
+number of visitors at an exhibition, noise levels near an airport,
+temperature on your favorite holiday location, temperature in the
+fridge and whatever you imagination can come up with.
+.PP
+You only need a sensor to measure the data and be able to feed the
+numbers into RRDtool. RRDtool then lets you create a database, store
+data in it, retrieve that data and create graphs in \s-1PNG\s0 format for
+display on a web browser. Those \s-1PNG\s0 images are dependent on the data
+you collected and could be, for instance, an overview of the average
+network usage, or the peaks that occurred.
+.Sh "What if I still have problems after reading this document?"
+.IX Subsection "What if I still have problems after reading this document?"
+First of all: read it again! You may have missed something.
+If you are unable to compile the sources and you have a fairly common
+\&\s-1OS\s0, it will probably not be the fault of RRDtool. There may be pre-compiled
+versions around on the Internet. If they come from trusted sources, get
+one of those.
+.PP
+If on the other hand the program works but does not give you the
+expected results, it will be a problem with configuring it. Review
+your configuration and compare it with the examples that follow.
+.PP
+There is a mailing list and an archive of it. Read the list for a few
+weeks and search the archive. It is considered rude to just ask
+a question without searching the archives: your problem may already have been
+solved for somebody else!  This is true for most, if not all, mailing lists
+and not only for this particular one. Look in the documentation that
+came with RRDtool for the location and usage of the list.
+.PP
+I suggest you take a moment to subscribe to the mailing list right now
+by sending an email to <rrd\-users\-request@lists.oetiker.ch> with a
+subject of \*(L"subscribe\*(R". If you ever want to leave this list, just write
+an email to the same address but now with a subject of \*(L"unsubscribe\*(R".
+.Sh "How will you help me?"
+.IX Subsection "How will you help me?"
+By giving you some detailed descriptions with detailed examples.
+I assume that following the instructions in the order presented
+will give you enough knowledge of RRDtool to experiment for yourself.
+If it doesn't work the first time, don't give up. Reread the stuff that
+you did understand, you may have missed something.
+.PP
+By following the examples you get some hands-on experience and, even
+more important, some background information of how it works.
+.PP
+You will need to know something about hexadecimal numbers. If you don't
+then start with reading bin_dec_hex before you continue here.
+.Sh "Your first Round Robin Database"
+.IX Subsection "Your first Round Robin Database"
+In my opinion the best way to learn something is to actually do it.
+Why not start right now?  We will create a database, put some values
+in it and extract this data again.  Your output should be the same
+as the output that is included in this document.
+.PP
+We will start with some easy stuff and compare a car with a router,
+or compare kilometers (miles if you wish) with bits and bytes. It's
+all the same: some number over some time.
+.PP
+Assume we have a device that transfers bytes to and from the Internet.
+This device keeps a counter that starts at zero when it is turned on,
+increasing with every byte that is transfered. This counter will probably have
+a maximum value. If this value is reached and an extra byte is counted,
+the counter starts over at zero. This is the same as many counters
+in the world such as the mileage counter in a car.
+.PP
+Most discussions about networking talk about bits per second so lets
+get used to that right away. Assume a byte is eight bits and start to
+think in bits not bytes. The counter, however, still counts bytes!
+In the \s-1SNMP\s0 world most of the counters are 32 bits. That means they are
+counting from 0 to 4'294'967'295. We will use these values in the examples.
+The device, when asked, returns the current value of the counter. We
+know the time that has passes since we last asked so we now know how
+many bytes have been transfered ***on average*** per second. This is
+not very hard to calculate. First in words, then in calculations:
+.IP "1." 3
+Take the current counter, subtract the previous value from it.
+.IP "2." 3
+Do the same with the current time and the previous time (in seconds).
+.IP "3." 3
+Divide the outcome of (1) by the outcome of (2), the result is
+the amount of bytes per second. Multiply by eight to get the
+number of bits per second (bps).
+.PP
+.Vb 1
+\&  bps = (counter_now \- counter_before) / (time_now \- time_before) * 8
+.Ve
+.PP
+For some people it may help to translate this to an automobile example.
+Do not try this example, and if you do, don't blame me for the results!
+.PP
+People who are not used to think in kilometers per hour can translate
+most into miles per hour by dividing km by 1.6 (close enough).
+I will use the following abbreviations:
+.PP
+.Vb 6
+\& M:    meter
+\& KM:   kilometer (= 1'000 meters).
+\& H:    hour
+\& S:    second
+\& KM/H: kilometers per hour
+\& M/S:  meters per second
+.Ve
+.PP
+You are driving a car. At 12:05 you read the counter in the dashboard
+and it tells you that the car has moved 12'345 \s-1KM\s0 until that moment.
+At 12:10 you look again, it reads 12'357 \s-1KM\s0. This means you have
+traveled 12 \s-1KM\s0 in five minutes. A scientist would translate that
+into meters per second and this makes a nice comparison toward the
+problem of (bytes per five minutes) versus (bits per second).
+.PP
+We traveled 12 kilometers which is 12'000 meters. We did that in five
+minutes or 300 seconds. Our speed is 12'000M / 300S or 40 M/S.
+.PP
+We could also calculate the speed in \s-1KM/H:\s0 12 times 5 minutes
+is an hour, so we have to multiply 12 \s-1KM\s0 by 12 to get 144 \s-1KM/H\s0.
+For our native English speaking friends: that's 90 \s-1MPH\s0 so don't
+try this example at home or where I live :)
+.PP
+Remember: these numbers are averages only.  There is no way to figure out
+from the numbers, if you drove at a constant speed.  There is an example
+later on in this tutorial that explains this.
+.PP
+I hope you understand that there is no difference in calculating M/S or
+bps; only the way we collect the data is different. Even the K from kilo
+is the same as in networking terms k also means 1'000.
+.PP
+We will now create a database where we can keep all these interesting
+numbers. The method used to start the program may differ slightly from
+\&\s-1OS\s0 to \s-1OS\s0, but I assume you can figure it out if it works different on
+your's. Make sure you do not overwrite any file on your system when
+executing the following command and type the whole line as one long
+line (I had to split it for readability)
+and skip all of the '\e' characters.

+.Sh "What has been created?"
+.IX Subsection "What has been created?"
+We created the round robin database called test (test.rrd) which starts at
+noon the day I started writing this document, 7th of March, 1999 (this date
+translates to 920'804'400 seconds as explained below). Our database holds
+one data source (\s-1DS\s0) named \*(L"speed\*(R" that represents a counter. This counter
+is read every five minutes (this is the default therefore you don't have to
+put \f(CW\*(C`\-\-step=300\*(C'\fR).  In the same database two round robin archives (RRAs)
+are kept, one averages the data every time it is read (e.g., there's nothing
+to average) and keeps 24 samples (24 times 5 minutes is 2 hours). The other
+averages 6 values (half hour) and contains 10 such averages (e.g. 5 hours).
+.PP
+RRDtool works with special time stamps coming from the \s-1UNIX\s0 world.
+This time stamp is the number of seconds that passed since January
+1st 1970 \s-1UTC\s0.  The time stamp value is translated into local time and
+it will therefore look different for different time zones.
+.PP
+Chances are that you are not in the same part of the world as I am.
+This means your time zone is different. In all examples where I talk
+about time, the hours may be wrong for you. This has little effect on
+the results of the examples, just correct the hours while reading.
+As an example: where I will see \*(L"12:05\*(R" the \s-1UK\s0 folks will see \*(L"11:05\*(R".
+.PP
+We now have to fill our database with some numbers. We'll pretend to
+have read the following numbers:
+.PP
+.Vb 15
+\& 12:05  12345 KM
+\& 12:10  12357 KM
+\& 12:15  12363 KM
+\& 12:20  12363 KM
+\& 12:25  12363 KM
+\& 12:30  12373 KM
+\& 12:35  12383 KM
+\& 12:40  12393 KM
+\& 12:45  12399 KM
+\& 12:50  12405 KM
+\& 12:55  12411 KM
+\& 13:00  12415 KM
+\& 13:05  12420 KM
+\& 13:10  12422 KM
+\& 13:15  12423 KM
+.Ve
+.PP
+We fill the database as follows:
+.PP
+.Vb 5

+.Ve
+.PP
+This reads: update our test database with the following numbers
+.PP
+.Vb 2
+\& time 920804700, value 12345
+\& time 920805000, value 12357
+.Ve
+.PP
+etcetera.
+.PP
+As you can see, it is possible to feed more than one value into the
+database in one command. I had to stop at three for readability but
+the real maximum per line is \s-1OS\s0 dependent.

+If it doesn't, something may be wrong.  Perhaps your \s-1OS\s0 will print
+\&\*(L"NaN\*(R" in a different form. \*(L"NaN\*(R" stands for \*(L"Not A Number\*(R".  If your \s-1OS\s0
+writes \*(L"U\*(R" or \*(L"\s-1UNKN\s0\*(R" or something similar that's okay.  If something
+else is wrong, it will probably be due to an error you made (assuming
+that my tutorial is correct of course :\-). In that case: delete the
+database and try again.  Sometimes things change.  This example used
+to provide numbers like \*(L"0.04\*(R" in stead of \*(L"4.00000e\-02\*(R".  Those are
+really the same numbers, just written down differently.  Don't be
+alarmed if a future version of rrdtool displays a slightly different
+form of output. The examples in this document are correct for version
+1.2.0 of RRDtool.
+.PP
+The meaning of the above output will become clear below.

+.PP
+This will create speed.png which starts at 12:00 and ends at 13:00.
+There is a definition of a variable called myspeed, using the data from \s-1RRA\s0
+\&\*(L"speed\*(R" out of database \*(L"test.rrd\*(R". The line drawn is 2 pixels high
+and represents the variable myspeed. The color is red (specified by
+its rgb\-representation, see below).
+.PP
+You'll notice that the start of the graph is not at 12:00 but at 12:05.
+This is because we have insufficient data to tell the average before
+that time. This will only happen when you miss some samples, this will
+not happen a lot, hopefully.
+.PP
+If this has worked: congratulations! If not, check what went wrong.
+.PP
+The colors are built up from red, green and blue. For each of the
+components, you specify how much to use in hexadecimal where 00 means
+not included and \s-1FF\s0 means fully included.

+When looking at the image, you notice that the horizontal axis is labeled
+12:10, 12:20, 12:30, 12:40 and 12:50. Sometimes a label doesn't fit (12:00
+and 13:00 would be candidates) so they are skipped.
+.PP
+The vertical axis displays the range we entered. We provided
+kilometers and when divided by 300 seconds, we get very small
+numbers. To be exact, the first value was 12 (12'357\-12'345) and divided
+by 300 this makes 0.04, which is displayed by RRDtool as \*(L"40 m\*(R"
+meaning \*(L"40/1'000\*(R". The \*(L"m\*(R" (milli) has nothing to do with meters,
+kilometers or millimeters! RRDtool doesn't know about the physical
+units of our data, it just works with dimensionless numbers.
+.PP
+If we had measured our distances in meters, this would have been
+(12'357'000\-12'345'000)/300 = 12'000/300 = 40.

+Note: Make sure not to forget the backslash \e in front of the

+After viewing this \s-1PNG\s0, you notice the \*(L"m\*(R" (milli) has
+disappeared. This it what the correct result would be. Also, a label

+the \s-1PNG\s0 should look the same.
+.PP
+The calculations are specified in the \s-1CDEF\s0 part above and are in

+\&\*(L"take the data source myspeed and the number 1000; multiply
+those\*(R". Don't bother with \s-1RPN\s0 yet, it will be explained later on in
+more detail. Also, you may want to read my tutorial on CDEFs and Steve
+Rader's tutorial on \s-1RPN\s0. But first finish this tutorial.

+Hang on! If we can multiply values with 1'000, it should also be possible
+to display kilometers per hour from the same data!
+.PP
+To change a value that is measured in meters per second:
+.PP
+.Vb 3
+\& Calculate meters per hour:     value * 3'600
+\& Calculate kilometers per hour: value / 1'000
+\& Together this makes:           value * (3'600/1'000) or value * 3.6
+.Ve
+.PP
+In our example database we made a mistake and we need to compensate for
+this by multiplying with 1'000. Applying that correction:
+.PP
+.Vb 1
+\& value * 3.6  * 1'000 == value * 3'600

+.Sh "Some words on \s-1SNMP\s0"
+.IX Subsection "Some words on SNMP"
+I can imagine very few people that will be able to get real data from
+their car every five minutes. All other people will have to settle for
+some other kind of counter. You could measure the number of pages
+printed by a printer, for example, the cups of coffee made by the
+coffee machine, a device that counts the electricity used,
+whatever. Any incrementing counter can be monitored and graphed using
+the stuff you learned so far. Later on we will also be able to monitor
+other types of values like temperature.
+.PP
+Most (?) people interested in RRDtool will use the counter that keeps track
+of octets (bytes) transfered by a network device. So let's do just
+that next. We will start with a description of how to collect data.
+.PP
+Some people will make a remark that there are tools which can do this data
+collection for you. They are right! However, I feel it is important that
+you understand they are not necessary. When you have to determine why
+things went wrong you need to know how they work.
+.PP
+One tool used in the example has been talked about very briefly in the
+beginning of this document, it is called \s-1SNMP\s0. It is a way of talking
+to networked equipment. The tool I use below is called \*(L"snmpget\*(R" and
+this is how it works:
+.PP
+.Vb 1
+\&   snmpget device password OID
+.Ve
+.PP
+or
+.PP
+.Vb 1
+\&   snmpget \-v[version] \-c[password] device OID
+.Ve
+.PP
+For device you substitute the name, or the \s-1IP\s0 address, of your device.
+For password you use the \*(L"community read string\*(R" as it is called in the
+\&\s-1SNMP\s0 world.  For some devices the default of \*(L"public\*(R" might work, however
+this can be disabled, altered or protected for privacy and security
+reasons.  Read the documentation that comes with your device or program.
+.PP
+Then there is this parameter, called \s-1OID\s0, which means \*(L"object identifier\*(R".
+.PP
+When you start to learn about \s-1SNMP\s0 it looks very confusing. It isn't
+all that difficult when you look at the Management Information Base
+(\*(L"\s-1MIB\s0\*(R").  It is an upside-down tree that describes data, with a single node
+as the root and from there a number of branches.  These branches end
+up in another node, they branch out, etc.  All the branches have a name
+and they form the path that we follow all the way down.  The branches
+that we follow are named: iso, org, dod, internet, mgmt and mib\-2.
+These names can also be written down as numbers and are 1 3 6 1 2 1.
+.PP
+.Vb 1
+\&   iso.org.dod.internet.mgmt.mib\-2 (1.3.6.1.2.1)
+.Ve
+.PP
+There is a lot of confusion about the leading dot that some programs
+use.  There is *no* leading dot in an \s-1OID\s0.  However, some programs
+can use the above part of OIDs as a default.  To indicate the difference
+between abbreviated OIDs and full OIDs they need a leading dot when
+you specify the complete \s-1OID\s0.  Often those programs will leave out
+the default portion when returning the data to you.  To make things
+worse, they have several default prefixes ...
+.PP
+Ok, lets continue to the start of our \s-1OID:\s0 we had 1.3.6.1.2.1
+From there, we are especially interested in the branch \*(L"interfaces\*(R"
+which has number 2 (e.g., 1.3.6.1.2.1.2 or 1.3.6.1.2.1.interfaces).
+.PP
+First, we have to get some \s-1SNMP\s0 program. First look if there is a
+pre-compiled package available for your \s-1OS\s0. This is the preferred way.
+If not, you will have to get the sources yourself and compile those.
+The Internet is full of sources, programs etc. Find information using
+a search engine or whatever you prefer.
+.PP
+Assume you got the program. First try to collect some data that is
+available on most systems. Remember: there is a short name for the
+part of the tree that interests us most in the world we live in!
+.PP
+I will give an example which can be used on Fedora Core 3.  If it
+doesn't work for you, work your way through the manual of snmp and
+adapt the example to make it work.
+.PP
+.Vb 1
+\&   snmpget \-v2c \-c public myrouter system.sysDescr.0
+.Ve
+.PP
+The device should answer with a description of itself, perhaps an
+empty one. Until you got a valid answer from a device, perhaps using a
+different \*(L"password\*(R", or a different device, there is no point in
+continuing.
+.PP
+.Vb 1
+\&   snmpget \-v2c \-c public myrouter interfaces.ifNumber.0
+.Ve
+.PP
+Hopefully you get a number as a result, the number of interfaces.
+If so, you can carry on and try a different program called \*(L"snmpwalk\*(R".
+.PP
+.Vb 1
+\&   snmpwalk \-v2c \-c public myrouter interfaces.ifTable.ifEntry.ifDescr
+.Ve
+.PP
+If it returns with a list of interfaces, you're almost there.
+Here's an example:
+   [user@host /home/alex]$ snmpwalk \-v2c \-c public cisco 2.2.1.2
+.PP
+.Vb 5
+\&   interfaces.ifTable.ifEntry.ifDescr.1 = "BRI0: B\-Channel 1"
+\&   interfaces.ifTable.ifEntry.ifDescr.2 = "BRI0: B\-Channel 2"
+\&   interfaces.ifTable.ifEntry.ifDescr.3 = "BRI0" Hex: 42 52 49 30
+\&   interfaces.ifTable.ifEntry.ifDescr.4 = "Ethernet0"
+\&   interfaces.ifTable.ifEntry.ifDescr.5 = "Loopback0"
+.Ve
+.PP
+On this cisco equipment, I would like to monitor the \*(L"Ethernet0\*(R"
+interface and from the above output I see that it is number four. I try:
+.PP
+.Vb 1
+\&   [user@host /home/alex]$ snmpget \-v2c \-c public cisco 2.2.1.10.4 2.2.1.16.4
+.Ve
+.PP
+.Vb 2
+\&   interfaces.ifTable.ifEntry.ifInOctets.4 = 2290729126
+\&   interfaces.ifTable.ifEntry.ifOutOctets.4 = 1256486519
+.Ve
+.PP
+So now I have two OIDs to monitor and they are (in full, this time):
+.PP
+.Vb 1
+\&   1.3.6.1.2.1.2.2.1.10
+.Ve
+.PP
+and
+.PP
+.Vb 1
+\&   1.3.6.1.2.1.2.2.1.16
+.Ve
+.PP
+both with an interface number of 4.
+.PP
+Don't get fooled, this wasn't my first try. It took some time for me too
+to understand what all these numbers mean. It does help a lot when they
+get translated into descriptive text... At least, when people are talking
+about MIBs and OIDs you know what it's all about.
+Do not forget the interface number (0 if it is not interface dependent)
+and try snmpwalk if you don't get an answer from snmpget.
+.PP
+If you understand the above section and get numbers from your device, continue
+on with this tutorial. If not, then go back and re-read this part.
+.Sh "A Real World Example"
+.IX Subsection "A Real World Example"
+Let the fun begin. First, create a new database. It contains data from
+two counters, called input and output. The data is put into archives
+that average it. They take 1, 6, 24 or 288 samples at a time.
+They also go into archives that keep the maximum numbers. This will be
+explained later on. The time in-between samples is 300 seconds, a good
+starting point, which is the same as five minutes.
+.PP

+.Ve
+.PP
+Lets try to be compatible with \s-1MRTG\s0 which stores about the following
+amount of data:

+\& 732 1\-day samples:     732   days
+.Ve
+.PP
+These ranges are appended, so the total amount of data stored in the
+database is approximately 797 days. RRDtool stores the data
+differently, it doesn't start the \*(L"weekly\*(R" archive where the \*(L"daily\*(R"
+archive stopped. For both archives the most recent data will be near
+\&\*(L"now\*(R" and therefore we will need to keep more data than \s-1MRTG\s0 does!

+an area for the \*(L"in\*(R" traffic and a line for the \*(L"out\*(R" traffic.

+View the image and keep logging data for a few more days.
+If you like, you could try the examples from the test database and

+.PP
+Suggestion: Display in bytes per second and in bits per second. Make
+the Ethernet graphics go red if they are over four megabits per
+second.
+.Sh "Consolidation Functions"
+.IX Subsection "Consolidation Functions"
+A few paragraphs back I mentioned the possibility of keeping
+the maximum values instead of the average values. Let's go
+into this a bit more.
+.PP
+Recall all the stuff about the speed of the car. Suppose we drove at 144
+\&\s-1KM/H\s0 during 5 minutes and then were stopped by the police for 25 minutes.
+At the end of the lecture we would take our laptop and create and view the
+image taken from the database. If we look at the second \s-1RRA\s0 we did
+create, we would have the average from 6 samples. The samples measured
+would be 144+0+0+0+0+0=144, divided by 30 minutes, corrected for the
+error by 1000, translated into \s-1KM/H\s0, with a result of 24 \s-1KM/H\s0.
+I would still get a ticket but not for speeding anymore :)
+.PP
+Obviously, in this case we shouldn't look at the averages. In some
+cases they are handy. If you want to know how many \s-1KM\s0 you had traveled,
+the averaged picture would be the right one to look at. On the other hand, for
+the speed that we traveled at, the maximum numbers seen is much more
+interesting. Later we will see more types.
+.PP
+It is the same for data. If you want to know the amount, look at the
+averages. If you want to know the rate, look at the maximum.
+Over time, they will grow apart more and more. In the last database
+we have created, there are two archives that keep data per day. The
+archive that keeps averages will show low numbers, the archive that
+shows maxima will have higher numbers.
+.PP
+For my car this would translate in averages per day of 96/24=4 \s-1KM/H\s0
+(as I travel about 94 kilometers on a day) during working days, and
+maxima of 120 \s-1KM/H\s0 (my top speed that I reach every day).
+.PP
+Big difference. Do not look at the second graph to estimate the
+distances that I travel and do not look at the first graph to
+estimate my speed. This will work if the samples are close together,
+as they are in five minutes, but not if you average.
+.PP
+On some days, I go for a long ride. If I go across Europe and travel
+for 12 hours, the first graph will rise to about 60 \s-1KM/H\s0. The second
+one will show 180 \s-1KM/H\s0. This means that I traveled a distance of 60
+\&\s-1KM/H\s0 times 24 H = 1440 \s-1KM\s0. I did this with a higher speed and a
+maximum around 180 \s-1KM/H\s0. However, it probably doesn't mean that I
+traveled for 8 hours at a constant speed of 180 \s-1KM/H\s0!
+.PP
+This is a real example: go with the flow through Germany (fast!) and stop
+a few times for gas and coffee. Drive slowly through Austria and the
+Netherlands. Be careful in the mountains and villages. If you would
+look at the graphs created from the five-minute averages you would
+get a totally different picture. You would see the same values on the
+average and maximum graphs (provided I measured every 300 seconds).
+You would be able to see when I stopped, when I was in top gear, when
+I drove over fast highways etc. The granularity of the data is much
+higher, so you can see more. However, this takes 12 samples per hour,
+or 288 values per day, so it would be a lot of data over a longer
+period of time. Therefore we average it, eventually to one value per
+day. From this one value, we cannot see much detail, of course.
+.PP
+Make sure you understand the last few paragraphs. There is no value
+in only a line and a few axis, you need to know what they mean and
+interpret the data in ana appropriate way. This is true for all data.
+.PP
+The biggest mistake you can make is to use the collected data for
+something that it is not suitable for. You would be better off if
+you didn't have the graph at all.
+.Sh "Let's review what you now should know"
+.IX Subsection "Let's review what you now should know"
+You know how to create a database and can put data in it. You can get
+the numbers out again by creating an image, do math on the data from
+the database and view the resulte instead of the raw data.  You know
+about the difference between averages and maxima, and when to use
+which (or at least you should have an idea).
+.PP
+RRDtool can do more than what we have learned up to now. Before you
+continue with the rest of this doc, I recommend that you reread from
+the start and try some modifications on the examples. Make sure you
+fully understand everything. It will be worth the effort and helps
+you not only with the rest of this tutorial, but also in your day to day
+monitoring long after you read this introduction.
+.Sh "Data Source Types"
+.IX Subsection "Data Source Types"
+All right, you feel like continuing. Welcome back and get ready
+for an increased speed in the examples and explanations.
+.PP
+You know that in order to view a counter over time, you have to
+take two numbers and divide the difference of them between the
+time lapsed.  This makes sense for the examples I gave you but there
+are other possibilities.  For instance, I'm able to retrieve the
+temperature from my router in three places namely the inlet, the
+so called hot-spot and the exhaust.  These values are not counters.
+If I take the difference of the two samples and divide that by
+300 seconds I would be asking for the temperature change per second.
+Hopefully this is zero! If not, the computer room is probably on fire :)
+.PP
+So, what can we do?  We can tell RRDtool to store the values we measure
+directly as they are (this is not entirely true but close enough). The
+graphs we make will look much better, they will show a rather constant
+value. I know when the router is busy (it
+works \-> it uses more electricity \-> it generates more heat \-> the
+temperature rises). I know when the doors are left open (the room is
+air conditioned) \-> the warm air from the rest of the building flows into the
+computer room \-> the inlet temperature rises). Etc. The data type we
+use when creating the database before was counter, we now have a
+different data type and thus a different name for it. It is called
+\&\s-1GAUGE\s0. There are more such data types:
+.PP
+.Vb 4
+\& \- COUNTER   we already know this one
+\& \- GAUGE     we just learned this one
+\& \- DERIVE
+\& \- ABSOLUTE
+.Ve
+.PP
+The two additional types are \s-1DERIVE\s0 and \s-1ABSOLUTE\s0. Absolute can be used like
+counter with one difference: RRDtool assumes the counter is reset when
+it's read. That is: its delta is known without calculation by RRDtool
+whereas RRDtool needs to calculate it for the counter type.
+Example: our first example (12'345, 12'357, 12'363, 12'363) would read:
+unknown, 12, 6, 0. The rest of the calculations stay the same.
+The other one, derive, is like counter. Unlike counter, it can also
+decrease so it can have a negative delta. Again, the rest of the
+calculations stay the same.

+Line A is a \s-1COUNTER\s0 type, so it should continuously increment and RRDtool
+must calculate the differences. Also, RRDtool needs to divide the
+difference by the amount of time lapsed. This should end up as a
+straight line at 1 (the deltas are 300, the time is 300).
+.IP "\(bu" 2
+Line B is of type \s-1GAUGE\s0. These are \*(L"real\*(R" values so they should match
+what we put in: a sort of a wave.
+.IP "\(bu" 2
+Line C is of type \s-1DERIVE\s0. It should be a counter that can decrease. It does
+so between 2'400 and 0, with 1'800 in\-between.
+.IP "\(bu" 2
+Line D is of type \s-1ABSOLUTE\s0. This is like counter but it works on
+values without calculating the difference. The numbers are the same
+and as you can see (hopefully) this has a different result.
+.PP
+This translates in the following values, starting at 23:10 and ending
+at 00:10 the next day (where \*(L"u\*(R" means unknown/unplotted):

+If your \s-1PNG\s0 shows all this, you know you have entered the data correctly,
+the RRDtool executable is working properly, your viewer doesn't fool you,
+and you successfully entered the year 2000 :)
+.PP
+You could try the same example four times, each time with only one of
+the lines.
+.PP
+Let's go over the data again:
+.IP "\(bu" 2
+Line A: 300,600,900 and so on. The counter delta is a constant 300 and
+so is the time delta. A number divided by itself is always 1 (except
+when dividing by zero which is undefined/illegal).
+.Sp
+Why is it that the first point is unknown? We do know what we put into
+the database, right? True, But we didn't have a value to calculate the delta
+from, so we don't know where we started. It would be wrong to assume we
+started at zero so we don't!
+.IP "\(bu" 2
+Line B: There is nothing to calculate. The numbers are as they are.
+.IP "\(bu" 2
+Line C: Again, the start-out value is unknown. The same story is holds
+as for line A. In this case the deltas are not constant, therefore the line
+is not either. If we would put the same numbers in the database as we did for
+line A, we would have gotten the same line. Unlike type counter,
+this type can decrease and I hope to show you later on why
+this makes a difference.
+.IP "\(bu" 2
+Line D: Here the device calculates the deltas. Therefore we \s-1DO\s0 know the
+first delta and it is plotted. We had the same input as with line A, but
+the meaning of this input is different and thus the line is different.
+In this case the deltas increase each time with 300. The time delta
+stays at a constant 300 and therefore the division of the two gives
+increasing values.
+.Sh "Counter Wraps"
+.IX Subsection "Counter Wraps"
+There are a few more basics to show. Some important options are still to
+be covered and we haven't look at counter wraps yet. First the counter wrap:
+In our car we notice that the counter shows 999'987. We travel 20 \s-1KM\s0 and
+the counter should go to 1'000'007. Unfortunately, there are only six digits
+on our counter so it really shows 000'007. If we would plot that on a type
+\&\s-1DERIVE\s0, it would mean that the counter was set back 999'980 \s-1KM\s0. It wasn't,
+and there has to be some protection for this. This protection is only
+available for type \s-1COUNTER\s0 which should be used for this kind of counter
+anyways. How does it work? Type counter should never decrease and
+therefore RRDtool must assume it wrapped if it does decrease!
+If the delta is negative, this can be compensated for by adding the
+maximum value of the counter + 1. For our car this would be:
+.PP
+.Vb 1
+\& Delta = 7 \- 999'987 = \-999'980    (instead of 1'000'007\-999'987=20)
+.Ve
+.PP
+.Vb 1
+\& Real delta = \-999'980 + 999'999 + 1 = 20
+.Ve
+.PP
+At the time of writing this document, RRDtool knows of counters that
+are either 32 bits or 64 bits of size. These counters can handle the
+following different values:
+.PP
+.Vb 2
+\& \- 32 bits: 0 ..           4'294'967'295
+\& \- 64 bits: 0 .. 18'446'744'073'709'551'615
+.Ve
+.PP
+If these numbers look strange to you, you can view them in
+their hexadecimal form:
+.PP
+.Vb 2
+\& \- 32 bits: 0 ..         FFFFFFFF
+\& \- 64 bits: 0 .. FFFFFFFFFFFFFFFF
+.Ve
+.PP
+RRDtool handles both counters the same. If an overflow occurs and
+the delta would be negative, RRDtool first adds the maximum of a small
+counter + 1 to the delta. If the delta is still negative, it had to be
+the large counter that wrapped. Add the maximum possible value of the
+large counter + 1 and subtract the erroneously added small value.
+.PP
+There is a risk in this: suppose the large counter wrapped while adding
+a huge delta, it could happen, theoretically, that adding the smaller value
+would make the delta positive. In this unlikely case the results would
+not be correct. The increase should be nearly as high as the maximum
+counter value for that to happen, so chances are you would have several
+other problems as well and this particular problem would not even be
+worth thinking about. Even though, I did include an example, so you
+can judge for yourself.
+.PP
+The next section gives you some numerical examples for counter\-wraps.
+Try to do the calculations yourself or just believe me if your calculator
+can't handle the numbers :)

+.Ve
+.PP
+As you can see from the last two examples, you need strange numbers
+for RRDtool to fail (provided it's bug free of course), so this should
+not happen. However, \s-1SNMP\s0 or whatever method you choose to collect the
+data, might also report wrong numbers occasionally.  We can't prevent all
+errors, but there are some things we can do. The RRDtool \*(L"create\*(R" command
+takes two special parameters for this. They define
+the minimum and maximum allowed values. Until now, we used \*(L"U\*(R", meaning
+\&\*(L"unknown\*(R". If you provide values for one or both of them and if RRDtool
+receives data points that are outside these limits, it will ignore those
+values. For a thermometer in degrees Celsius, the absolute minimum is
+just under \-273. For my router, I can assume this minimum is much higher
+so I would set it to 10, where as the maximum temperature I would
+set to 80. Any higher and the device would be out of order.
+.PP
+For the speed of my car, I would never expect negative numbers and
+also I would not expect a speed  higher than 230. Anything else,
+and there must have been an error. Remember: the opposite is not true,
+if the numbers pass this check, it doesn't mean that they are
+correct. Always judge the graph with a healthy dose of suspicion if it
+seems weird to you.
+.Sh "Data Resampling"
+.IX Subsection "Data Resampling"
+One important feature of RRDtool has not been explained yet: it is
+virtually impossible to collect data and feed it into RRDtool on exact
+intervals. RRDtool therefore interpolates the data, so they are stored
+on exact intervals. If you do not know what this means or how it
+works, then here's the help you seek:
+.PP
+Suppose a counter increases by exactly one for every second. You want
+to measure it in 300 seconds intervals. You should retrieve values
+that are exactly 300 apart. However, due to various circumstances you
+are a few seconds late and the interval is 303. The delta will also be
+303 in that case. Obviously, RRDtool should not put 303 in the database
+and make you believe that the counter increased by 303 in 300 seconds.
+This is where RRDtool interpolates: it alters the 303 value as if it
+would have been stored earlier and it will be 300 in 300 seconds.
+Next time you are at exactly the right time. This means that the current
+interval is 297 seconds and also the counter increased by 297. Again,
+RRDtool interpolates and stores 300 as it should be.
+.PP
+.Vb 1

+RRDtool) I've learned while just reading the list without posting to
+it. I did not need to ask the basic questions as they are answered in
+the \s-1FAQ\s0 (read it!) and in various mails by other users. With

+<h1><a name="description">DESCRIPTION</a></h1>
+<p>RRDtool is written by Tobias Oetiker &lt;<a href="mailto:tobi@oetiker.ch">tobi@oetiker.ch</a>&gt; with
+contributions from many people all around the world. This document is
+written by Alex van den Bogaerdt &lt;<a href="mailto:alex@ergens.op.het.net">alex@ergens.op.het.net</a>&gt; to help you
+understand what RRDtool is and what it can do for you.</p>
+<p>The documentation provided with RRDtool can be too technical for some
+people. This tutorial is here to help you understand the basics of
+RRDtool. It should prepare you to read the documentation yourself.
+It also explains the general things about statistics with a focus on
+networking.</p>

+<p>
+</p>
+<h2><a name="important">Important</a></h2>
+<p>Please don't skip ahead in this document!  The first part of this
+document explains the basics and may be boring.  But if you don't
+understand the basics, the examples will not be as meaningful to you.</p>
+<p>
+</p>
+<h2><a name="what_is_rrdtool">What is RRDtool?</a></h2>
+<p>RRDtool refers to Round Robin Database tool.
+Round robin is a technique that works with a fixed amount of data, and a
+pointer to the current element. Think of a circle with some dots plotted
+on the edge -- these dots are the places where data can be stored. Draw an
+arrow from the center of the circle to one of the dots -- this is the pointer.
+When the current data is read or written, the pointer moves to the next
+element. As we are on a circle there is neither a beginning nor an end, you can
+go on and on and on. After a while, all the available places will be used and
+the process automatically reuses old locations. This way, the dataset
+will not grow in size and therefore requires no maintenance.
+RRDtool works with with Round Robin Databases (RRDs). It stores and retrieves
+data from them.</p>
+<p>
+</p>
+<h2><a name="what_data_can_be_put_into_an_rrd">What data can be put into an RRD?</a></h2>
+<p>You name it, it will probably fit as long as it is some sort of time-series
+data. This means you have to be able to measure some value at several points in time and
+provide this information to RRDtool. If you can do this, RRDtool will be
+able to store it. The values must be numerical but don't have to be
+integers, as is the case with MRTG (the next section will give more details
+on this more specialized application).</p>
+<p>Many examples below talk about SNMP which is an acronym for Simple Network
+Management Protocol. ``Simple'' refers to the protocol -- it does not
+mean it is simple to manage or monitor a network. After working your
+way through this document, you should know enough to be able to
+understand what people are talking about. For now, just realize that
+SNMP can be used to query devices for the values of counters they keep. It
+is the value from those counters that we want to store in the RRD.</p>
+<p>
+</p>
+<h2><a name="what_can_i_do_with_this_tool">What can I do with this tool?</a></h2>
+<p>RRDtool originated from MRTG (Multi Router Traffic Grapher). MRTG
+started as a tiny little script for graphing the use of a university's
+connection to the Internet. MRTG was later (ab-)used as a tool for
+graphing other data sources including temperature, speed, voltage,
+number of printouts and the like.</p>
+<p>Most likely you will start to use RRDtool to store and process data
+collected via SNMP. The data will most likely be bytes (or bits)
+transfered from and to a network or a computer.  But it can also be
+used to display tidal waves, solar radiation, power consumption,
+number of visitors at an exhibition, noise levels near an airport,
+temperature on your favorite holiday location, temperature in the
+fridge and whatever you imagination can come up with.</p>
+<p>You only need a sensor to measure the data and be able to feed the
+numbers into RRDtool. RRDtool then lets you create a database, store
+data in it, retrieve that data and create graphs in PNG format for
+display on a web browser. Those PNG images are dependent on the data
+you collected and could be, for instance, an overview of the average
+network usage, or the peaks that occurred.</p>
+<p>
+</p>
+<h2><a name="what_if_i_still_have_problems_after_reading_this_document">What if I still have problems after reading this document?</a></h2>
+<p>First of all: read it again! You may have missed something.
+If you are unable to compile the sources and you have a fairly common
+OS, it will probably not be the fault of RRDtool. There may be pre-compiled
+versions around on the Internet. If they come from trusted sources, get
+one of those.</p>
+<p>If on the other hand the program works but does not give you the
+expected results, it will be a problem with configuring it. Review
+your configuration and compare it with the examples that follow.</p>
+<p>There is a mailing list and an archive of it. Read the list for a few
+weeks and search the archive. It is considered rude to just ask
+a question without searching the archives: your problem may already have been
+solved for somebody else!  This is true for most, if not all, mailing lists
+and not only for this particular one. Look in the documentation that
+came with RRDtool for the location and usage of the list.</p>
+<p>I suggest you take a moment to subscribe to the mailing list right now
+by sending an email to &lt;<a href="mailto:rrd-users-request@lists.oetiker.ch">rrd-users-request@lists.oetiker.ch</a>&gt; with a
+subject of ``subscribe''. If you ever want to leave this list, just write
+an email to the same address but now with a subject of ``unsubscribe''.</p>
+<p>
+</p>
+<h2><a name="how_will_you_help_me">How will you help me?</a></h2>
+<p>By giving you some detailed descriptions with detailed examples.
+I assume that following the instructions in the order presented
+will give you enough knowledge of RRDtool to experiment for yourself.
+If it doesn't work the first time, don't give up. Reread the stuff that
+you did understand, you may have missed something.</p>
+<p>By following the examples you get some hands-on experience and, even
+more important, some background information of how it works.</p>
+<p>You will need to know something about hexadecimal numbers. If you don't
+then start with reading <a href="././bin_dec_hex.html">the bin_dec_hex manpage</a> before you continue here.</p>
+<p>
+</p>
+<h2><a name="your_first_round_robin_database">Your first Round Robin Database</a></h2>
+<p>In my opinion the best way to learn something is to actually do it.
+Why not start right now?  We will create a database, put some values
+in it and extract this data again.  Your output should be the same
+as the output that is included in this document.</p>
+<p>We will start with some easy stuff and compare a car with a router,
+or compare kilometers (miles if you wish) with bits and bytes. It's
+all the same: some number over some time.</p>
+<p>Assume we have a device that transfers bytes to and from the Internet.
+This device keeps a counter that starts at zero when it is turned on,
+increasing with every byte that is transfered. This counter will probably have
+a maximum value. If this value is reached and an extra byte is counted,
+the counter starts over at zero. This is the same as many counters
+in the world such as the mileage counter in a car.</p>
+<p>Most discussions about networking talk about bits per second so lets
+get used to that right away. Assume a byte is eight bits and start to
+think in bits not bytes. The counter, however, still counts bytes!
+In the SNMP world most of the counters are 32 bits. That means they are
+counting from 0 to 4'294'967'295. We will use these values in the examples.
+The device, when asked, returns the current value of the counter. We
+know the time that has passes since we last asked so we now know how
+many bytes have been transfered ***on average*** per second. This is
+not very hard to calculate. First in words, then in calculations:</p>
+<ol>
+<li>
+<p>Take the current counter, subtract the previous value from it.</p>
+</li>
+<li>
+<p>Do the same with the current time and the previous time (in seconds).</p>
+</li>
+<li>
+<p>Divide the outcome of (1) by the outcome of (2), the result is
+the amount of bytes per second. Multiply by eight to get the
+number of bits per second (bps).</p>
+</li>
+</ol>
+<pre>
+  bps = (counter_now - counter_before) / (time_now - time_before) * 8</pre>
+<p>For some people it may help to translate this to an automobile example.
+Do not try this example, and if you do, don't blame me for the results!</p>
+<p>People who are not used to think in kilometers per hour can translate
+most into miles per hour by dividing km by 1.6 (close enough).
+I will use the following abbreviations:</p>
+<pre>
+ M:    meter
+ KM:   kilometer (= 1'000 meters).
+ H:    hour
+ S:    second
+ KM/H: kilometers per hour
+ M/S:  meters per second</pre>
+<p>You are driving a car. At 12:05 you read the counter in the dashboard
+and it tells you that the car has moved 12'345 KM until that moment.
+At 12:10 you look again, it reads 12'357 KM. This means you have
+traveled 12 KM in five minutes. A scientist would translate that
+into meters per second and this makes a nice comparison toward the
+problem of (bytes per five minutes) versus (bits per second).</p>
+<p>We traveled 12 kilometers which is 12'000 meters. We did that in five
+minutes or 300 seconds. Our speed is 12'000M / 300S or 40 M/S.</p>
+<p>We could also calculate the speed in KM/H: 12 times 5 minutes
+is an hour, so we have to multiply 12 KM by 12 to get 144 KM/H.
+For our native English speaking friends: that's 90 MPH so don't
+try this example at home or where I live :)</p>
+<p>Remember: these numbers are averages only.  There is no way to figure out
+from the numbers, if you drove at a constant speed.  There is an example
+later on in this tutorial that explains this.</p>
+<p>I hope you understand that there is no difference in calculating M/S or
+bps; only the way we collect the data is different. Even the K from kilo
+is the same as in networking terms k also means 1'000.</p>
+<p>We will now create a database where we can keep all these interesting
+numbers. The method used to start the program may differ slightly from
+OS to OS, but I assume you can figure it out if it works different on
+your's. Make sure you do not overwrite any file on your system when
+executing the following command and type the whole line as one long
+line (I had to split it for readability)
+and skip all of the '\' characters.</p>
+<pre>
+   rrdtool create test.rrd             \
+            --start 920804400          \
+            DS:speed:COUNTER:600:U:U   \
+            RRA:AVERAGE:0.5:1:24       \
+            RRA:AVERAGE:0.5:6:10</pre>
+<p>(So enter: <code>rrdtool create test.rrd --start 920804400 DS ...</code>)</p>
+<p>
+</p>
+<h2><a name="what_has_been_created">What has been created?</a></h2>
+<p>We created the round robin database called test (test.rrd) which starts at
+noon the day I started writing this document, 7th of March, 1999 (this date
+translates to 920'804'400 seconds as explained below). Our database holds
+one data source (DS) named ``speed'' that represents a counter. This counter
+is read every five minutes (this is the default therefore you don't have to
+put <code>--step=300</code>).  In the same database two round robin archives (RRAs)
+are kept, one averages the data every time it is read (e.g., there's nothing
+to average) and keeps 24 samples (24 times 5 minutes is 2 hours). The other
+averages 6 values (half hour) and contains 10 such averages (e.g. 5 hours).</p>
+<p>RRDtool works with special time stamps coming from the UNIX world.
+This time stamp is the number of seconds that passed since January
+1st 1970 UTC.  The time stamp value is translated into local time and
+it will therefore look different for different time zones.</p>
+<p>Chances are that you are not in the same part of the world as I am.
+This means your time zone is different. In all examples where I talk
+about time, the hours may be wrong for you. This has little effect on
+the results of the examples, just correct the hours while reading.
+As an example: where I will see ``12:05'' the UK folks will see ``11:05''.</p>
+<p>We now have to fill our database with some numbers. We'll pretend to
+have read the following numbers:</p>
+<pre>
+ 12:05  12345 KM
+ 12:10  12357 KM
+ 12:15  12363 KM
+ 12:20  12363 KM
+ 12:25  12363 KM
+ 12:30  12373 KM
+ 12:35  12383 KM
+ 12:40  12393 KM
+ 12:45  12399 KM
+ 12:50  12405 KM
+ 12:55  12411 KM
+ 13:00  12415 KM
+ 13:05  12420 KM
+ 13:10  12422 KM
+ 13:15  12423 KM</pre>
+<p>We fill the database as follows:</p>
+<pre>
+ rrdtool update test.rrd 920804700:12345 920805000:12357 920805300:12363
+ rrdtool update test.rrd 920805600:12363 920805900:12363 920806200:12373
+ rrdtool update test.rrd 920806500:12383 920806800:12393 920807100:12399
+ rrdtool update test.rrd 920807400:12405 920807700:12411 920808000:12415
+ rrdtool update test.rrd 920808300:12420 920808600:12422 920808900:12423</pre>
+<p>This reads: update our test database with the following numbers</p>
+<pre>
+ time 920804700, value 12345
+ time 920805000, value 12357</pre>
+<p>etcetera.</p>
+<p>As you can see, it is possible to feed more than one value into the
+database in one command. I had to stop at three for readability but
+the real maximum per line is OS dependent.</p>
+<p>We can now retrieve the data from our database using ``rrdtool fetch'':</p>
+<pre>
+ rrdtool fetch test.rrd AVERAGE --start 920804400 --end 920809200</pre>
+<p>It should return the following output:</p>
+<pre>
+                          speed</pre>
+<pre>
+ 920804700: nan
+ 920805000: 4.0000000000e-02

+ 920808900: 3.3333333333e-03
+ 920809200: nan</pre>
+<p>If it doesn't, something may be wrong.  Perhaps your OS will print
+``NaN'' in a different form. ``NaN'' stands for ``Not A Number''.  If your OS
+writes ``U'' or ``UNKN'' or something similar that's okay.  If something
+else is wrong, it will probably be due to an error you made (assuming
+that my tutorial is correct of course :-). In that case: delete the
+database and try again.  Sometimes things change.  This example used
+to provide numbers like ``0.04'' in stead of ``4.00000e-02''.  Those are
+really the same numbers, just written down differently.  Don't be
+alarmed if a future version of rrdtool displays a slightly different
+form of output. The examples in this document are correct for version
+1.2.0 of RRDtool.</p>
+<p>The meaning of the above output will become clear below.</p>
+<p>
+</p>
+<h2><a name="time_to_create_some_graphics">Time to create some graphics</a></h2>
+<p>Try the following command:</p>
+<pre>
+ rrdtool graph speed.png                                 \
+         --start 920804400 --end 920808000               \
+         DEF:myspeed=test.rrd:speed:AVERAGE              \
+         LINE2:myspeed#FF0000</pre>
+<p>This will create speed.png which starts at 12:00 and ends at 13:00.
+There is a definition of a variable called myspeed, using the data from RRA
+``speed'' out of database ``test.rrd''. The line drawn is 2 pixels high
+and represents the variable myspeed. The color is red (specified by
+its rgb-representation, see below).</p>
+<p>You'll notice that the start of the graph is not at 12:00 but at 12:05.
+This is because we have insufficient data to tell the average before
+that time. This will only happen when you miss some samples, this will
+not happen a lot, hopefully.</p>
+<p>If this has worked: congratulations! If not, check what went wrong.</p>
+<p>The colors are built up from red, green and blue. For each of the
+components, you specify how much to use in hexadecimal where 00 means
+not included and FF means fully included.
+The ``color'' white is a mixture of red, green and blue: FFFFFF
+The ``color'' black is all colors off: 000000</p>
+<pre>
+   red     #FF0000
+   green   #00FF00
+   blue    #0000FF
+   magenta #FF00FF     (mixed red with blue)
+   gray    #555555     (one third of all components)</pre>
+<p>Additionally you can add an alpha channel (transparency).  The default
+will be ``FF'' which means non-transparent.</p>
+<p>The PNG you just created can be displayed using your favorite image
+viewer.  Web browsers will display the PNG via the URL
+``file:///the/path/to/speed.png''</p>
+<p>
+</p>
+<h2><a name="graphics_with_some_math">Graphics with some math</a></h2>
+<p>When looking at the image, you notice that the horizontal axis is labeled
+12:10, 12:20, 12:30, 12:40 and 12:50. Sometimes a label doesn't fit (12:00
+and 13:00 would be candidates) so they are skipped.</p>
+<p>The vertical axis displays the range we entered. We provided
+kilometers and when divided by 300 seconds, we get very small
+numbers. To be exact, the first value was 12 (12'357-12'345) and divided
+by 300 this makes 0.04, which is displayed by RRDtool as ``40 m''
+meaning ``40/1'000''. The ``m'' (milli) has nothing to do with meters,
+kilometers or millimeters! RRDtool doesn't know about the physical
+units of our data, it just works with dimensionless numbers.</p>
+<p>If we had measured our distances in meters, this would have been
+(12'357'000-12'345'000)/300 = 12'000/300 = 40.</p>
+<p>As most people have a better feel for numbers in this range, we'll
+correct that. We could recreate our database and store the correct
+data, but there is a better way: we do some calculations while creating
+the png file!</p>
+<pre>
+   rrdtool graph speed2.png                           \
+      --start 920804400 --end 920808000               \
+      --vertical-label m/s                            \
+      DEF:myspeed=test.rrd:speed:AVERAGE              \
+      CDEF:realspeed=myspeed,1000,\*                  \
+      LINE2:realspeed#FF0000</pre>
+<p>Note: Make sure not to forget the backslash \ in front of the
+multiplication operator * above. The backslash is needed to ``escape''
+the * as some operating systems might interpret and expand * instead
+of passing it to the rrdtool command.</p>
+<p>After viewing this PNG, you notice the ``m'' (milli) has
+disappeared. This it what the correct result would be. Also, a label
+has been added to the image.  Apart from the things mentioned above,
+the PNG should look the same.</p>
+<p>The calculations are specified in the CDEF part above and are in
+Reverse Polish Notation (``RPN''). What we requested RRDtool to do is:
+``take the data source myspeed and the number 1000; multiply
+those''. Don't bother with RPN yet, it will be explained later on in
+more detail. Also, you may want to read my tutorial on CDEFs and Steve
+Rader's tutorial on RPN. But first finish this tutorial.</p>
+<p>Hang on! If we can multiply values with 1'000, it should also be possible
+to display kilometers per hour from the same data!</p>
+<p>To change a value that is measured in meters per second:</p>
+<pre>
+ Calculate meters per hour:     value * 3'600
+ Calculate kilometers per hour: value / 1'000
+ Together this makes:           value * (3'600/1'000) or value * 3.6</pre>
+<p>In our example database we made a mistake and we need to compensate for
+this by multiplying with 1'000. Applying that correction:</p>
+<pre>
+ value * 3.6  * 1'000 == value * 3'600</pre>
+<p>Now let's create this PNG, and add some more magic ...</p>

+<h2><a name="updates_in_reality">Updates in Reality</a></h2>
+<p>We've already used the <code>update</code> command: it took one or more
+parameters in the form of ``&lt;time&gt;:&lt;value&gt;''. You'll be glad to know
+that you can specify the current time by filling in a ``N'' as the time.
+Or you could use the ``time'' function in Perl (the shortest example in
+this tutorial):</p>
+<pre>
+   perl -e 'print time, &quot;\n&quot; '</pre>
+<p>How to run a program on regular intervals is OS specific. But here is

+<pre>
+   - Get the value and put it in variable &quot;$speed&quot;
+   - rrdtool update speed.rrd N:$speed</pre>
+<p>(do not try this with our test database, we'll use it in further examples)</p>
+<p>This is all. Run the above script every five minutes. When you need to know

+<h2><a name="some_words_on_snmp">Some words on SNMP</a></h2>
+<p>I can imagine very few people that will be able to get real data from
+their car every five minutes. All other people will have to settle for
+some other kind of counter. You could measure the number of pages
+printed by a printer, for example, the cups of coffee made by the
+coffee machine, a device that counts the electricity used,
+whatever. Any incrementing counter can be monitored and graphed using
+the stuff you learned so far. Later on we will also be able to monitor
+other types of values like temperature.</p>
+<p>Most (?) people interested in RRDtool will use the counter that keeps track
+of octets (bytes) transfered by a network device. So let's do just
+that next. We will start with a description of how to collect data.</p>
+<p>Some people will make a remark that there are tools which can do this data
+collection for you. They are right! However, I feel it is important that
+you understand they are not necessary. When you have to determine why
+things went wrong you need to know how they work.</p>
+<p>One tool used in the example has been talked about very briefly in the
+beginning of this document, it is called SNMP. It is a way of talking
+to networked equipment. The tool I use below is called ``snmpget'' and
+this is how it works:</p>
+<pre>
+   snmpget device password OID</pre>
+<p>or</p>
+<pre>
+   snmpget -v[version] -c[password] device OID</pre>
+<p>For device you substitute the name, or the IP address, of your device.
+For password you use the ``community read string'' as it is called in the
+SNMP world.  For some devices the default of ``public'' might work, however
+this can be disabled, altered or protected for privacy and security
+reasons.  Read the documentation that comes with your device or program.</p>
+<p>Then there is this parameter, called OID, which means ``object identifier''.</p>
+<p>When you start to learn about SNMP it looks very confusing. It isn't
+all that difficult when you look at the Management Information Base
+(``MIB'').  It is an upside-down tree that describes data, with a single node
+as the root and from there a number of branches.  These branches end
+up in another node, they branch out, etc.  All the branches have a name
+and they form the path that we follow all the way down.  The branches
+that we follow are named: iso, org, dod, internet, mgmt and mib-2.
+These names can also be written down as numbers and are 1 3 6 1 2 1.</p>
+<pre>
+   iso.org.dod.internet.mgmt.mib-2 (1.3.6.1.2.1)</pre>
+<p>There is a lot of confusion about the leading dot that some programs
+use.  There is *no* leading dot in an OID.  However, some programs
+can use the above part of OIDs as a default.  To indicate the difference
+between abbreviated OIDs and full OIDs they need a leading dot when
+you specify the complete OID.  Often those programs will leave out
+the default portion when returning the data to you.  To make things
+worse, they have several default prefixes ...</p>
+<p>Ok, lets continue to the start of our OID: we had 1.3.6.1.2.1
+From there, we are especially interested in the branch ``interfaces''
+which has number 2 (e.g., 1.3.6.1.2.1.2 or 1.3.6.1.2.1.interfaces).</p>
+<p>First, we have to get some SNMP program. First look if there is a
+pre-compiled package available for your OS. This is the preferred way.
+If not, you will have to get the sources yourself and compile those.
+The Internet is full of sources, programs etc. Find information using
+a search engine or whatever you prefer.</p>
+<p>Assume you got the program. First try to collect some data that is
+available on most systems. Remember: there is a short name for the
+part of the tree that interests us most in the world we live in!</p>
+<p>I will give an example which can be used on Fedora Core 3.  If it
+doesn't work for you, work your way through the manual of snmp and
+adapt the example to make it work.</p>
+<pre>
+   snmpget -v2c -c public myrouter system.sysDescr.0</pre>
+<p>The device should answer with a description of itself, perhaps an
+empty one. Until you got a valid answer from a device, perhaps using a
+different ``password'', or a different device, there is no point in
+continuing.</p>
+<pre>
+   snmpget -v2c -c public myrouter interfaces.ifNumber.0</pre>
+<p>Hopefully you get a number as a result, the number of interfaces.
+If so, you can carry on and try a different program called ``snmpwalk''.</p>
+<pre>
+   snmpwalk -v2c -c public myrouter interfaces.ifTable.ifEntry.ifDescr</pre>
+<p>If it returns with a list of interfaces, you're almost there.
+Here's an example:
+   [user@host /home/alex]$ snmpwalk -v2c -c public cisco 2.2.1.2</p>
+<pre>
+   interfaces.ifTable.ifEntry.ifDescr.1 = &quot;BRI0: B-Channel 1&quot;
+   interfaces.ifTable.ifEntry.ifDescr.2 = &quot;BRI0: B-Channel 2&quot;
+   interfaces.ifTable.ifEntry.ifDescr.3 = &quot;BRI0&quot; Hex: 42 52 49 30
+   interfaces.ifTable.ifEntry.ifDescr.4 = &quot;Ethernet0&quot;
+   interfaces.ifTable.ifEntry.ifDescr.5 = &quot;Loopback0&quot;</pre>
+<p>On this cisco equipment, I would like to monitor the ``Ethernet0''
+interface and from the above output I see that it is number four. I try:</p>
+<pre>
+   [user@host /home/alex]$ snmpget -v2c -c public cisco 2.2.1.10.4 2.2.1.16.4</pre>
+<pre>
+   interfaces.ifTable.ifEntry.ifInOctets.4 = 2290729126
+   interfaces.ifTable.ifEntry.ifOutOctets.4 = 1256486519</pre>
+<p>So now I have two OIDs to monitor and they are (in full, this time):</p>
+<pre>
+   1.3.6.1.2.1.2.2.1.10</pre>
+<p>and</p>
+<pre>
+   1.3.6.1.2.1.2.2.1.16</pre>
+<p>both with an interface number of 4.</p>
+<p>Don't get fooled, this wasn't my first try. It took some time for me too
+to understand what all these numbers mean. It does help a lot when they
+get translated into descriptive text... At least, when people are talking
+about MIBs and OIDs you know what it's all about.
+Do not forget the interface number (0 if it is not interface dependent)
+and try snmpwalk if you don't get an answer from snmpget.</p>
+<p>If you understand the above section and get numbers from your device, continue
+on with this tutorial. If not, then go back and re-read this part.</p>
+<p>

+<h2><a name="a_real_world_example">A Real World Example</a></h2>
+<p>Let the fun begin. First, create a new database. It contains data from
+two counters, called input and output. The data is put into archives
+that average it. They take 1, 6, 24 or 288 samples at a time.
+They also go into archives that keep the maximum numbers. This will be
+explained later on. The time in-between samples is 300 seconds, a good
+starting point, which is the same as five minutes.</p>
+<pre>
+ 1 sample &quot;averaged&quot; stays 1 period of 5 minutes
+ 6 samples averaged become one average on 30 minutes
+ 24 samples averaged become one average on 2 hours
+ 288 samples averaged become one average on 1 day</pre>
+<p>Lets try to be compatible with MRTG which stores about the following
+amount of data:</p>
+<pre>
+ 600 5-minute samples:    2   days and 2 hours
+ 600 30-minute samples:  12.5 days
+ 600 2-hour samples:     50   days
+ 732 1-day samples:     732   days</pre>
+<p>These ranges are appended, so the total amount of data stored in the
+database is approximately 797 days. RRDtool stores the data
+differently, it doesn't start the ``weekly'' archive where the ``daily''
+archive stopped. For both archives the most recent data will be near
+``now'' and therefore we will need to keep more data than MRTG does!</p>
+<p>We will need:</p>
+<pre>
+ 600 samples of 5 minutes  (2 days and 2 hours)
+ 700 samples of 30 minutes (2 days and 2 hours, plus 12.5 days)
+ 775 samples of 2 hours    (above + 50 days)
+ 797 samples of 1 day      (above + 732 days, rounded up to 797)</pre>
+<pre>
+   rrdtool create myrouter.rrd         \
+            DS:input:COUNTER:600:U:U   \
+            DS:output:COUNTER:600:U:U  \

+            RRA:MAX:0.5:288:797</pre>
+<p>Next thing to do is to collect data and store it. Here is an example.
+It is written partially in pseudo code,  you will have to find out what
+to do exactly on your OS to make it work.</p>
+<pre>
+   while not the end of the universe
+   do
+      get result of
+         snmpget router community 2.2.1.10.4
+      into variable $in
+      get result of
+         snmpget router community 2.2.1.16.4
+      into variable $out</pre>
+<pre>
+      rrdtool update myrouter.rrd N:$in:$out</pre>
+<pre>
+      wait for 5 minutes
+   done</pre>
+<p>Then, after collecting data for a day, try to create an image using:</p>
+<pre>
+   rrdtool graph myrouter-day.png --start -86400 \
+            DEF:inoctets=myrouter.rrd:input:AVERAGE \
+            DEF:outoctets=myrouter.rrd:output:AVERAGE \
+            AREA:inoctets#00FF00:&quot;In traffic&quot; \
+            LINE1:outoctets#0000FF:&quot;Out traffic&quot;</pre>
+<p>This should produce a picture with one day worth of traffic.
+One day is 24 hours of 60 minutes of 60 seconds: 24*60*60=86'400, we
+start at now minus 86'400 seconds. We define (with DEFs) inoctets and
+outoctets as the average values from the database myrouter.rrd and draw
+an area for the ``in'' traffic and a line for the ``out'' traffic.</p>
+<p>View the image and keep logging data for a few more days.
+If you like, you could try the examples from the test database and
+see if you can get various options and calculations to work.</p>
+<p>Suggestion: Display in bytes per second and in bits per second. Make
+the Ethernet graphics go red if they are over four megabits per
+second.</p>
+<p>
+</p>
+<h2><a name="consolidation_functions">Consolidation Functions</a></h2>
+<p>A few paragraphs back I mentioned the possibility of keeping
+the maximum values instead of the average values. Let's go
+into this a bit more.</p>
+<p>Recall all the stuff about the speed of the car. Suppose we drove at 144
+KM/H during 5 minutes and then were stopped by the police for 25 minutes.
+At the end of the lecture we would take our laptop and create and view the
+image taken from the database. If we look at the second RRA we did
+create, we would have the average from 6 samples. The samples measured
+would be 144+0+0+0+0+0=144, divided by 30 minutes, corrected for the
+error by 1000, translated into KM/H, with a result of 24 KM/H.
+I would still get a ticket but not for speeding anymore :)</p>
+<p>Obviously, in this case we shouldn't look at the averages. In some
+cases they are handy. If you want to know how many KM you had traveled,
+the averaged picture would be the right one to look at. On the other hand, for
+the speed that we traveled at, the maximum numbers seen is much more
+interesting. Later we will see more types.</p>
+<p>It is the same for data. If you want to know the amount, look at the
+averages. If you want to know the rate, look at the maximum.
+Over time, they will grow apart more and more. In the last database
+we have created, there are two archives that keep data per day. The
+archive that keeps averages will show low numbers, the archive that
+shows maxima will have higher numbers.</p>
+<p>For my car this would translate in averages per day of 96/24=4 KM/H
+(as I travel about 94 kilometers on a day) during working days, and
+maxima of 120 KM/H (my top speed that I reach every day).</p>
+<p>Big difference. Do not look at the second graph to estimate the
+distances that I travel and do not look at the first graph to
+estimate my speed. This will work if the samples are close together,
+as they are in five minutes, but not if you average.</p>
+<p>On some days, I go for a long ride. If I go across Europe and travel
+for 12 hours, the first graph will rise to about 60 KM/H. The second
+one will show 180 KM/H. This means that I traveled a distance of 60
+KM/H times 24 H = 1440 KM. I did this with a higher speed and a
+maximum around 180 KM/H. However, it probably doesn't mean that I
+traveled for 8 hours at a constant speed of 180 KM/H!</p>
+<p>This is a real example: go with the flow through Germany (fast!) and stop
+a few times for gas and coffee. Drive slowly through Austria and the
+Netherlands. Be careful in the mountains and villages. If you would
+look at the graphs created from the five-minute averages you would
+get a totally different picture. You would see the same values on the
+average and maximum graphs (provided I measured every 300 seconds).
+You would be able to see when I stopped, when I was in top gear, when
+I drove over fast highways etc. The granularity of the data is much
+higher, so you can see more. However, this takes 12 samples per hour,
+or 288 values per day, so it would be a lot of data over a longer
+period of time. Therefore we average it, eventually to one value per
+day. From this one value, we cannot see much detail, of course.</p>
+<p>Make sure you understand the last few paragraphs. There is no value
+in only a line and a few axis, you need to know what they mean and
+interpret the data in ana appropriate way. This is true for all data.</p>
+<p>The biggest mistake you can make is to use the collected data for
+something that it is not suitable for. You would be better off if
+you didn't have the graph at all.</p>
+<p>
+</p>
+<h2><a name="let_s_review_what_you_now_should_know">Let's review what you now should know</a></h2>
+<p>You know how to create a database and can put data in it. You can get
+the numbers out again by creating an image, do math on the data from
+the database and view the resulte instead of the raw data.  You know
+about the difference between averages and maxima, and when to use
+which (or at least you should have an idea).</p>
+<p>RRDtool can do more than what we have learned up to now. Before you
+continue with the rest of this doc, I recommend that you reread from
+the start and try some modifications on the examples. Make sure you
+fully understand everything. It will be worth the effort and helps
+you not only with the rest of this tutorial, but also in your day to day
+monitoring long after you read this introduction.</p>
+<p>
+</p>
+<h2><a name="data_source_types">Data Source Types</a></h2>
+<p>All right, you feel like continuing. Welcome back and get ready
+for an increased speed in the examples and explanations.</p>
+<p>You know that in order to view a counter over time, you have to
+take two numbers and divide the difference of them between the
+time lapsed.  This makes sense for the examples I gave you but there
+are other possibilities.  For instance, I'm able to retrieve the
+temperature from my router in three places namely the inlet, the
+so called hot-spot and the exhaust.  These values are not counters.
+If I take the difference of the two samples and divide that by
+300 seconds I would be asking for the temperature change per second.
+Hopefully this is zero! If not, the computer room is probably on fire :)</p>
+<p>So, what can we do?  We can tell RRDtool to store the values we measure
+directly as they are (this is not entirely true but close enough). The
+graphs we make will look much better, they will show a rather constant
+value. I know when the router is busy (it
+works -&gt; it uses more electricity -&gt; it generates more heat -&gt; the
+temperature rises). I know when the doors are left open (the room is
+air conditioned) -&gt; the warm air from the rest of the building flows into the
+computer room -&gt; the inlet temperature rises). Etc. The data type we
+use when creating the database before was counter, we now have a
+different data type and thus a different name for it. It is called
+GAUGE. There are more such data types:</p>
+<pre>
+ - COUNTER   we already know this one
+ - GAUGE     we just learned this one
+ - DERIVE
+ - ABSOLUTE</pre>
+<p>The two additional types are DERIVE and ABSOLUTE. Absolute can be used like
+counter with one difference: RRDtool assumes the counter is reset when
+it's read. That is: its delta is known without calculation by RRDtool
+whereas RRDtool needs to calculate it for the counter type.
+Example: our first example (12'345, 12'357, 12'363, 12'363) would read:
+unknown, 12, 6, 0. The rest of the calculations stay the same.
+The other one, derive, is like counter. Unlike counter, it can also
+decrease so it can have a negative delta. Again, the rest of the
+calculations stay the same.</p>

+<ul>
+<li>
+<p>Line A is a COUNTER type, so it should continuously increment and RRDtool
+must calculate the differences. Also, RRDtool needs to divide the
+difference by the amount of time lapsed. This should end up as a
+straight line at 1 (the deltas are 300, the time is 300).</p>
+</li>
+<li>
+<p>Line B is of type GAUGE. These are ``real'' values so they should match
+what we put in: a sort of a wave.</p>
+</li>
+<li>
+<p>Line C is of type DERIVE. It should be a counter that can decrease. It does
+so between 2'400 and 0, with 1'800 in-between.</p>
+</li>
+<li>
+<p>Line D is of type ABSOLUTE. This is like counter but it works on
+values without calculating the difference. The numbers are the same
+and as you can see (hopefully) this has a different result.</p>
+</li>
+</ul>
+<p>This translates in the following values, starting at 23:10 and ending
+at 00:10 the next day (where ``u'' means unknown/unplotted):</p>
+<pre>
+ - Line A:  u  u  1  1  1  1  1  1  1  1  1  u
+ - Line B:  u  1  3  5  3  1  2  4  6  4  2  u
+ - Line C:  u  u  2  2  2  0 -2 -6  2  0  2  u
+ - Line D:  u  1  2  3  4  5  6  7  8  9 10  u</pre>
+<p>If your PNG shows all this, you know you have entered the data correctly,
+the RRDtool executable is working properly, your viewer doesn't fool you,
+and you successfully entered the year 2000 :)</p>
+<p>You could try the same example four times, each time with only one of
+the lines.</p>
+<p>Let's go over the data again:</p>
+<ul>
+<li>
+<p>Line A: 300,600,900 and so on. The counter delta is a constant 300 and
+so is the time delta. A number divided by itself is always 1 (except
+when dividing by zero which is undefined/illegal).</p>
+<p>Why is it that the first point is unknown? We do know what we put into
+the database, right? True, But we didn't have a value to calculate the delta
+from, so we don't know where we started. It would be wrong to assume we
+started at zero so we don't!</p>
+</li>
+<li>
+<p>Line B: There is nothing to calculate. The numbers are as they are.</p>
+</li>
+<li>
+<p>Line C: Again, the start-out value is unknown. The same story is holds
+as for line A. In this case the deltas are not constant, therefore the line
+is not either. If we would put the same numbers in the database as we did for
+line A, we would have gotten the same line. Unlike type counter,
+this type can decrease and I hope to show you later on why
+this makes a difference.</p>
+</li>
+<li>
+<p>Line D: Here the device calculates the deltas. Therefore we DO know the
+first delta and it is plotted. We had the same input as with line A, but
+the meaning of this input is different and thus the line is different.
+In this case the deltas increase each time with 300. The time delta
+stays at a constant 300 and therefore the division of the two gives
+increasing values.</p>
+</li>
+</ul>
+<p>
+</p>
+<h2><a name="counter_wraps">Counter Wraps</a></h2>
+<p>There are a few more basics to show. Some important options are still to
+be covered and we haven't look at counter wraps yet. First the counter wrap:
+In our car we notice that the counter shows 999'987. We travel 20 KM and
+the counter should go to 1'000'007. Unfortunately, there are only six digits
+on our counter so it really shows 000'007. If we would plot that on a type
+DERIVE, it would mean that the counter was set back 999'980 KM. It wasn't,
+and there has to be some protection for this. This protection is only
+available for type COUNTER which should be used for this kind of counter
+anyways. How does it work? Type counter should never decrease and
+therefore RRDtool must assume it wrapped if it does decrease!
+If the delta is negative, this can be compensated for by adding the
+maximum value of the counter + 1. For our car this would be:</p>
+<pre>
+ Delta = 7 - 999'987 = -999'980    (instead of 1'000'007-999'987=20)</pre>
+<pre>
+ Real delta = -999'980 + 999'999 + 1 = 20</pre>
+<p>At the time of writing this document, RRDtool knows of counters that
+are either 32 bits or 64 bits of size. These counters can handle the
+following different values:</p>
+<pre>
+ - 32 bits: 0 ..           4'294'967'295
+ - 64 bits: 0 .. 18'446'744'073'709'551'615</pre>
+<p>If these numbers look strange to you, you can view them in
+their hexadecimal form:</p>
+<pre>
+ - 32 bits: 0 ..         FFFFFFFF
+ - 64 bits: 0 .. FFFFFFFFFFFFFFFF</pre>
+<p>RRDtool handles both counters the same. If an overflow occurs and
+the delta would be negative, RRDtool first adds the maximum of a small
+counter + 1 to the delta. If the delta is still negative, it had to be
+the large counter that wrapped. Add the maximum possible value of the
+large counter + 1 and subtract the erroneously added small value.</p>
+<p>There is a risk in this: suppose the large counter wrapped while adding
+a huge delta, it could happen, theoretically, that adding the smaller value
+would make the delta positive. In this unlikely case the results would
+not be correct. The increase should be nearly as high as the maximum
+counter value for that to happen, so chances are you would have several
+other problems as well and this particular problem would not even be
+worth thinking about. Even though, I did include an example, so you
+can judge for yourself.</p>
+<p>The next section gives you some numerical examples for counter-wraps.
+Try to do the calculations yourself or just believe me if your calculator
+can't handle the numbers :)</p>

+<p>As you can see from the last two examples, you need strange numbers
+for RRDtool to fail (provided it's bug free of course), so this should
+not happen. However, SNMP or whatever method you choose to collect the
+data, might also report wrong numbers occasionally.  We can't prevent all
+errors, but there are some things we can do. The RRDtool ``create'' command
+takes two special parameters for this. They define
+the minimum and maximum allowed values. Until now, we used ``U'', meaning
+``unknown''. If you provide values for one or both of them and if RRDtool
+receives data points that are outside these limits, it will ignore those
+values. For a thermometer in degrees Celsius, the absolute minimum is
+just under -273. For my router, I can assume this minimum is much higher
+so I would set it to 10, where as the maximum temperature I would
+set to 80. Any higher and the device would be out of order.</p>
+<p>For the speed of my car, I would never expect negative numbers and
+also I would not expect a speed  higher than 230. Anything else,
+and there must have been an error. Remember: the opposite is not true,
+if the numbers pass this check, it doesn't mean that they are
+correct. Always judge the graph with a healthy dose of suspicion if it
+seems weird to you.</p>
+<p>
+</p>
+<h2><a name="data_resampling">Data Resampling</a></h2>
+<p>One important feature of RRDtool has not been explained yet: it is
+virtually impossible to collect data and feed it into RRDtool on exact
+intervals. RRDtool therefore interpolates the data, so they are stored
+on exact intervals. If you do not know what this means or how it
+works, then here's the help you seek:</p>
+<p>Suppose a counter increases by exactly one for every second. You want
+to measure it in 300 seconds intervals. You should retrieve values
+that are exactly 300 apart. However, due to various circumstances you
+are a few seconds late and the interval is 303. The delta will also be
+303 in that case. Obviously, RRDtool should not put 303 in the database
+and make you believe that the counter increased by 303 in 300 seconds.
+This is where RRDtool interpolates: it alters the 303 value as if it
+would have been stored earlier and it will be 300 in 300 seconds.
+Next time you are at exactly the right time. This means that the current
+interval is 297 seconds and also the counter increased by 297. Again,
+RRDtool interpolates and stores 300 as it should be.</p>
+<pre>
+      in the RRD                 in reality</pre>
+<pre>
+ time+000:   0 delta=&quot;U&quot;   time+000:    0 delta=&quot;U&quot;
+ time+300: 300 delta=300   time+300:  300 delta=300
+ time+600: 600 delta=300   time+603:  603 delta=303
+ time+900: 900 delta=300   time+900:  900 delta=297</pre>
+<p>Let's create two identical databases. I've chosen the time range 920'805'000
+to 920'805'900 as this goes very well with the example numbers.</p>

+=head1 NAME
+
+rrdtutorial - Alex van den Bogaerdt's RRDtool tutorial
+
+=head1 DESCRIPTION
+
+RRDtool is written by Tobias Oetiker E<lt>tobi@oetiker.chE<gt> with
+contributions from many people all around the world. This document is
+written by Alex van den Bogaerdt E<lt>alex@ergens.op.het.netE<gt> to help you
+understand what RRDtool is and what it can do for you.
+
+The documentation provided with RRDtool can be too technical for some
+people. This tutorial is here to help you understand the basics of
+RRDtool. It should prepare you to read the documentation yourself.
+It also explains the general things about statistics with a focus on
+networking.
+
+=head1 TUTORIAL
+
+=head2 Important
+
+Please don't skip ahead in this document!  The first part of this
+document explains the basics and may be boring.  But if you don't
+understand the basics, the examples will not be as meaningful to you.
+
+=head2 What is RRDtool?
+
+RRDtool refers to Round Robin Database tool.
+Round robin is a technique that works with a fixed amount of data, and a
+pointer to the current element. Think of a circle with some dots plotted
+on the edge -- these dots are the places where data can be stored. Draw an
+arrow from the center of the circle to one of the dots -- this is the pointer.
+When the current data is read or written, the pointer moves to the next
+element. As we are on a circle there is neither a beginning nor an end, you can
+go on and on and on. After a while, all the available places will be used and
+the process automatically reuses old locations. This way, the dataset
+will not grow in size and therefore requires no maintenance.
+RRDtool works with with Round Robin Databases (RRDs). It stores and retrieves
+data from them.
+
+=head2 What data can be put into an RRD?
+
+You name it, it will probably fit as long as it is some sort of time-series
+data. This means you have to be able to measure some value at several points in time and
+provide this information to RRDtool. If you can do this, RRDtool will be
+able to store it. The values must be numerical but don't have to be
+integers, as is the case with MRTG (the next section will give more details
+on this more specialized application).
+
+Many examples below talk about SNMP which is an acronym for Simple Network
+Management Protocol. "Simple" refers to the protocol -- it does not
+mean it is simple to manage or monitor a network. After working your
+way through this document, you should know enough to be able to
+understand what people are talking about. For now, just realize that
+SNMP can be used to query devices for the values of counters they keep. It
+is the value from those counters that we want to store in the RRD.
+
+=head2 What can I do with this tool?
+
+RRDtool originated from MRTG (Multi Router Traffic Grapher). MRTG
+started as a tiny little script for graphing the use of a university's
+connection to the Internet. MRTG was later (ab-)used as a tool for
+graphing other data sources including temperature, speed, voltage,
+number of printouts and the like.
+
+Most likely you will start to use RRDtool to store and process data
+collected via SNMP. The data will most likely be bytes (or bits)
+transfered from and to a network or a computer.  But it can also be
+used to display tidal waves, solar radiation, power consumption,
+number of visitors at an exhibition, noise levels near an airport,
+temperature on your favorite holiday location, temperature in the
+fridge and whatever you imagination can come up with.
+
+You only need a sensor to measure the data and be able to feed the
+numbers into RRDtool. RRDtool then lets you create a database, store
+data in it, retrieve that data and create graphs in PNG format for
+display on a web browser. Those PNG images are dependent on the data
+you collected and could be, for instance, an overview of the average
+network usage, or the peaks that occurred.
+
+=head2 What if I still have problems after reading this document?
+
+First of all: read it again! You may have missed something.
+If you are unable to compile the sources and you have a fairly common
+OS, it will probably not be the fault of RRDtool. There may be pre-compiled
+versions around on the Internet. If they come from trusted sources, get
+one of those.
+
+If on the other hand the program works but does not give you the
+expected results, it will be a problem with configuring it. Review
+your configuration and compare it with the examples that follow.
+
+There is a mailing list and an archive of it. Read the list for a few
+weeks and search the archive. It is considered rude to just ask
+a question without searching the archives: your problem may already have been
+solved for somebody else!  This is true for most, if not all, mailing lists
+and not only for this particular one. Look in the documentation that
+came with RRDtool for the location and usage of the list.
+
+I suggest you take a moment to subscribe to the mailing list right now
+by sending an email to E<lt>rrd-users-request@lists.oetiker.chE<gt> with a
+subject of "subscribe". If you ever want to leave this list, just write
+an email to the same address but now with a subject of "unsubscribe".
+
+=head2 How will you help me?
+
+By giving you some detailed descriptions with detailed examples.
+I assume that following the instructions in the order presented
+will give you enough knowledge of RRDtool to experiment for yourself.
+If it doesn't work the first time, don't give up. Reread the stuff that
+you did understand, you may have missed something.
+
+By following the examples you get some hands-on experience and, even
+more important, some background information of how it works.
+
+You will need to know something about hexadecimal numbers. If you don't
+then start with reading L<bin_dec_hex> before you continue here.
+
+=head2 Your first Round Robin Database
+
+In my opinion the best way to learn something is to actually do it.
+Why not start right now?  We will create a database, put some values
+in it and extract this data again.  Your output should be the same
+as the output that is included in this document.
+
+We will start with some easy stuff and compare a car with a router,
+or compare kilometers (miles if you wish) with bits and bytes. It's
+all the same: some number over some time.
+
+Assume we have a device that transfers bytes to and from the Internet.
+This device keeps a counter that starts at zero when it is turned on,
+increasing with every byte that is transfered. This counter will probably have
+a maximum value. If this value is reached and an extra byte is counted,
+the counter starts over at zero. This is the same as many counters
+in the world such as the mileage counter in a car.
+
+Most discussions about networking talk about bits per second so lets
+get used to that right away. Assume a byte is eight bits and start to
+think in bits not bytes. The counter, however, still counts bytes!
+In the SNMP world most of the counters are 32 bits. That means they are
+counting from 0 to 4'294'967'295. We will use these values in the examples.
+The device, when asked, returns the current value of the counter. We
+know the time that has passes since we last asked so we now know how
+many bytes have been transfered ***on average*** per second. This is
+not very hard to calculate. First in words, then in calculations:
+
+=over 3
+
+=item 1.
+
+Take the current counter, subtract the previous value from it.
+
+=item 2.
+
+Do the same with the current time and the previous time (in seconds).
+
+=item 3.
+
+Divide the outcome of (1) by the outcome of (2), the result is
+the amount of bytes per second. Multiply by eight to get the
+number of bits per second (bps).
+
+=back
+
+  bps = (counter_now - counter_before) / (time_now - time_before) * 8
+
+For some people it may help to translate this to an automobile example.
+Do not try this example, and if you do, don't blame me for the results!
+
+People who are not used to think in kilometers per hour can translate
+most into miles per hour by dividing km by 1.6 (close enough).
+I will use the following abbreviations:
+
+ M:    meter
+ KM:   kilometer (= 1'000 meters).
+ H:    hour
+ S:    second
+ KM/H: kilometers per hour
+ M/S:  meters per second
+
+You are driving a car. At 12:05 you read the counter in the dashboard
+and it tells you that the car has moved 12'345 KM until that moment.
+At 12:10 you look again, it reads 12'357 KM. This means you have
+traveled 12 KM in five minutes. A scientist would translate that
+into meters per second and this makes a nice comparison toward the
+problem of (bytes per five minutes) versus (bits per second).
+
+We traveled 12 kilometers which is 12'000 meters. We did that in five
+minutes or 300 seconds. Our speed is 12'000M / 300S or 40 M/S.
+
+We could also calculate the speed in KM/H: 12 times 5 minutes
+is an hour, so we have to multiply 12 KM by 12 to get 144 KM/H.
+For our native English speaking friends: that's 90 MPH so don't
+try this example at home or where I live :)
+
+Remember: these numbers are averages only.  There is no way to figure out
+from the numbers, if you drove at a constant speed.  There is an example
+later on in this tutorial that explains this.
+
+I hope you understand that there is no difference in calculating M/S or
+bps; only the way we collect the data is different. Even the K from kilo
+is the same as in networking terms k also means 1'000.
+
+We will now create a database where we can keep all these interesting
+numbers. The method used to start the program may differ slightly from
+OS to OS, but I assume you can figure it out if it works different on
+your's. Make sure you do not overwrite any file on your system when
+executing the following command and type the whole line as one long
+line (I had to split it for readability)
+and skip all of the '\' characters.
+
+   rrdtool create test.rrd             \
+            --start 920804400          \
+            DS:speed:COUNTER:600:U:U   \
+            RRA:AVERAGE:0.5:1:24       \
+            RRA:AVERAGE:0.5:6:10
+
+(So enter: C<rrdtool create test.rrd --start 920804400 DS ...>)
+
+=head2 What has been created?
+
+We created the round robin database called test (test.rrd) which starts at
+noon the day I started writing this document, 7th of March, 1999 (this date
+translates to 920'804'400 seconds as explained below). Our database holds
+one data source (DS) named "speed" that represents a counter. This counter
+is read every five minutes (this is the default therefore you don't have to
+put C<--step=300>).  In the same database two round robin archives (RRAs)
+are kept, one averages the data every time it is read (e.g., there's nothing
+to average) and keeps 24 samples (24 times 5 minutes is 2 hours). The other
+averages 6 values (half hour) and contains 10 such averages (e.g. 5 hours).
+
+RRDtool works with special time stamps coming from the UNIX world.
+This time stamp is the number of seconds that passed since January
+1st 1970 UTC.  The time stamp value is translated into local time and
+it will therefore look different for different time zones.
+
+Chances are that you are not in the same part of the world as I am.
+This means your time zone is different. In all examples where I talk
+about time, the hours may be wrong for you. This has little effect on
+the results of the examples, just correct the hours while reading.
+As an example: where I will see "12:05" the UK folks will see "11:05".
+
+We now have to fill our database with some numbers. We'll pretend to
+have read the following numbers:
+
+ 12:05 12345 KM
+ 12:10 12357 KM
+ 12:15 12363 KM
+ 12:20 12363 KM
+ 12:25 12363 KM
+ 12:30 12373 KM
+ 12:35 12383 KM
+ 12:40 12393 KM
+ 12:45 12399 KM
+ 12:50 12405 KM
+ 12:55 12411 KM
+ 13:00 12415 KM
+ 13:05 12420 KM
+ 13:10 12422 KM
+ 13:15 12423 KM
+
+We fill the database as follows:
+
+ rrdtool update test.rrd 920804700:12345 920805000:12357 920805300:12363
+ rrdtool update test.rrd 920805600:12363 920805900:12363 920806200:12373
+ rrdtool update test.rrd 920806500:12383 920806800:12393 920807100:12399
+ rrdtool update test.rrd 920807400:12405 920807700:12411 920808000:12415
+ rrdtool update test.rrd 920808300:12420 920808600:12422 920808900:12423
+
+This reads: update our test database with the following numbers
+
+ time 920804700, value 12345
+ time 920805000, value 12357
+
+etcetera.
+
+As you can see, it is possible to feed more than one value into the
+database in one command. I had to stop at three for readability but
+the real maximum per line is OS dependent.
+
+We can now retrieve the data from our database using "rrdtool fetch":
+
+ rrdtool fetch test.rrd AVERAGE --start 920804400 --end 920809200
+
+It should return the following output:
+
+                          speed
+
+ 920804700: nan
+ 920805000: 4.0000000000e-02
+ 920805300: 2.0000000000e-02
+ 920805600: 0.0000000000e+00
+ 920805900: 0.0000000000e+00
+ 920806200: 3.3333333333e-02
+ 920806500: 3.3333333333e-02
+ 920806800: 3.3333333333e-02
+ 920807100: 2.0000000000e-02
+ 920807400: 2.0000000000e-02
+ 920807700: 2.0000000000e-02
+ 920808000: 1.3333333333e-02
+ 920808300: 1.6666666667e-02
+ 920808600: 6.6666666667e-03
+ 920808900: 3.3333333333e-03
+ 920809200: nan
+
+If it doesn't, something may be wrong.  Perhaps your OS will print
+"NaN" in a different form. "NaN" stands for "Not A Number".  If your OS
+writes "U" or "UNKN" or something similar that's okay.  If something
+else is wrong, it will probably be due to an error you made (assuming
+that my tutorial is correct of course :-). In that case: delete the
+database and try again.  Sometimes things change.  This example used
+to provide numbers like "0.04" in stead of "4.00000e-02".  Those are
+really the same numbers, just written down differently.  Don't be
+alarmed if a future version of rrdtool displays a slightly different
+form of output. The examples in this document are correct for version
+1.2.0 of RRDtool.
+
+The meaning of the above output will become clear below.
+
+=head2 Time to create some graphics
+
+Try the following command:
+
+ rrdtool graph speed.png                                 \
+         --start 920804400 --end 920808000               \
+         DEF:myspeed=test.rrd:speed:AVERAGE              \
+         LINE2:myspeed#FF0000
+
+This will create speed.png which starts at 12:00 and ends at 13:00.
+There is a definition of a variable called myspeed, using the data from RRA
+"speed" out of database "test.rrd". The line drawn is 2 pixels high
+and represents the variable myspeed. The color is red (specified by
+its rgb-representation, see below).
+
+You'll notice that the start of the graph is not at 12:00 but at 12:05.
+This is because we have insufficient data to tell the average before
+that time. This will only happen when you miss some samples, this will
+not happen a lot, hopefully.
+
+If this has worked: congratulations! If not, check what went wrong.
+
+
+The colors are built up from red, green and blue. For each of the
+components, you specify how much to use in hexadecimal where 00 means
+not included and FF means fully included.
+The "color" white is a mixture of red, green and blue: FFFFFF
+The "color" black is all colors off: 000000
+
+   red     #FF0000
+   green   #00FF00
+   blue    #0000FF
+   magenta #FF00FF     (mixed red with blue)
+   gray    #555555     (one third of all components)
+
+Additionally you can add an alpha channel (transparency).  The default
+will be "FF" which means non-transparent.
+
+The PNG you just created can be displayed using your favorite image
+viewer.  Web browsers will display the PNG via the URL
+"file:///the/path/to/speed.png"
+
+=head2 Graphics with some math
+
+When looking at the image, you notice that the horizontal axis is labeled
+12:10, 12:20, 12:30, 12:40 and 12:50. Sometimes a label doesn't fit (12:00
+and 13:00 would be candidates) so they are skipped.
+
+The vertical axis displays the range we entered. We provided
+kilometers and when divided by 300 seconds, we get very small
+numbers. To be exact, the first value was 12 (12'357-12'345) and divided
+by 300 this makes 0.04, which is displayed by RRDtool as "40 m"
+meaning "40/1'000". The "m" (milli) has nothing to do with meters,
+kilometers or millimeters! RRDtool doesn't know about the physical
+units of our data, it just works with dimensionless numbers.
+
+If we had measured our distances in meters, this would have been
+(12'357'000-12'345'000)/300 = 12'000/300 = 40.
+
+As most people have a better feel for numbers in this range, we'll
+correct that. We could recreate our database and store the correct
+data, but there is a better way: we do some calculations while creating
+the png file!
+
+   rrdtool graph speed2.png                           \
+      --start 920804400 --end 920808000               \
+      --vertical-label m/s                            \
+      DEF:myspeed=test.rrd:speed:AVERAGE              \
+      CDEF:realspeed=myspeed,1000,\*                  \
+      LINE2:realspeed#FF0000
+
+Note: Make sure not to forget the backslash \ in front of the
+multiplication operator * above. The backslash is needed to "escape"
+the * as some operating systems might interpret and expand * instead
+of passing it to the rrdtool command.
+
+After viewing this PNG, you notice the "m" (milli) has
+disappeared. This it what the correct result would be. Also, a label
+has been added to the image.  Apart from the things mentioned above,
+the PNG should look the same.
+
+The calculations are specified in the CDEF part above and are in
+Reverse Polish Notation ("RPN"). What we requested RRDtool to do is:
+"take the data source myspeed and the number 1000; multiply
+those". Don't bother with RPN yet, it will be explained later on in
+more detail. Also, you may want to read my tutorial on CDEFs and Steve
+Rader's tutorial on RPN. But first finish this tutorial.
+
+Hang on! If we can multiply values with 1'000, it should also be possible
+to display kilometers per hour from the same data!
+
+To change a value that is measured in meters per second:
+
+ Calculate meters per hour:     value * 3'600
+ Calculate kilometers per hour: value / 1'000
+ Together this makes:           value * (3'600/1'000) or value * 3.6
+
+In our example database we made a mistake and we need to compensate for
+this by multiplying with 1'000. Applying that correction:
+
+ value * 3.6  * 1'000 == value * 3'600
+
+Now let's create this PNG, and add some more magic ...
+
+ rrdtool graph speed3.png                             \
+      --start 920804400 --end 920808000               \
+      --vertical-label km/h                           \
+      DEF:myspeed=test.rrd:speed:AVERAGE              \
+      "CDEF:kmh=myspeed,3600,*"                       \
+      CDEF:fast=kmh,100,GT,kmh,0,IF                   \
+      CDEF:good=kmh,100,GT,0,kmh,IF                   \
+      HRULE:100#0000FF:"Maximum allowed"              \
+      AREA:good#00FF00:"Good speed"                   \
+      AREA:fast#FF0000:"Too fast"
+
+Note: here we use another means to escape the * operator by enclosing
+the whole string in double quotes.
+
+This graph looks much better. Speed is shown in KM/H and there is even
+an extra line with the maximum allowed speed (on the road I travel
+on). I also changed the colors used to display speed and changed it
+from a line into an area.
+
+The calculations are more complex now. For speed measurements within
+the speed limit they are:
+
+   Check if kmh is greater than 100    ( kmh,100 ) GT
+   If so, return 0, else kmh           ((( kmh,100 ) GT ), 0, kmh) IF
+
+For values above the speed limit:
+
+   Check if kmh is greater than 100    ( kmh,100 ) GT
+   If so, return kmh, else return 0    ((( kmh,100) GT ), kmh, 0) IF
+
+=head2 Graphics Magic
+
+I like to believe there are virtually no limits to how RRDtool graph
+can manipulate data. I will not explain how it works, but look at the
+following PNG:
+
+   rrdtool graph speed4.png                           \
+      --start 920804400 --end 920808000               \
+      --vertical-label km/h                           \
+      DEF:myspeed=test.rrd:speed:AVERAGE              \
+      "CDEF:kmh=myspeed,3600,*"                       \
+      CDEF:fast=kmh,100,GT,100,0,IF                   \
+      CDEF:over=kmh,100,GT,kmh,100,-,0,IF             \
+      CDEF:good=kmh,100,GT,0,kmh,IF                   \
+      HRULE:100#0000FF:"Maximum allowed"              \
+      AREA:good#00FF00:"Good speed"                   \
+      AREA:fast#550000:"Too fast"                     \
+      STACK:over#FF0000:"Over speed"
+
+Let's create a quick and dirty HTML page to view the three PNGs:
+
+   <HTML><HEAD><TITLE>Speed</TITLE></HEAD><BODY>
+   <IMG src="speed2.png" alt="Speed in meters per second">
+   <BR>
+   <IMG src="speed3.png" alt="Speed in kilometers per hour">
+   <BR>
+   <IMG src="speed4.png" alt="Traveled too fast?">
+   </BODY></HTML>
+
+Name the file "speed.html" or similar, and look at it in your web browser.
+
+Now, all you have to do is measure the values regularly and update the
+database.  When you want to view the data, recreate the PNGs and make
+sure to refresh them in your browser. (Note: just clicking reload may
+not be enough, especially when proxies are involved.  Try shift-reload
+or ctrl-F5).
+
+=head2 Updates in Reality
+
+We've already used the C<update> command: it took one or more
+parameters in the form of "<time>:<value>". You'll be glad to know
+that you can specify the current time by filling in a "N" as the time.
+Or you could use the "time" function in Perl (the shortest example in
+this tutorial):
+
+   perl -e 'print time, "\n" '
+
+How to run a program on regular intervals is OS specific. But here is
+an example in pseudo code:
+
+   - Get the value and put it in variable "$speed"
+   - rrdtool update speed.rrd N:$speed
+
+(do not try this with our test database, we'll use it in further examples)
+
+This is all. Run the above script every five minutes. When you need to know
+what the graphs look like, run the examples above. You could put them
+in a script as well. After running that script, view the page
+index.html we created above.
+
+=head2 Some words on SNMP
+
+I can imagine very few people that will be able to get real data from
+their car every five minutes. All other people will have to settle for
+some other kind of counter. You could measure the number of pages
+printed by a printer, for example, the cups of coffee made by the
+coffee machine, a device that counts the electricity used,
+whatever. Any incrementing counter can be monitored and graphed using
+the stuff you learned so far. Later on we will also be able to monitor
+other types of values like temperature.
+
+Most (?) people interested in RRDtool will use the counter that keeps track
+of octets (bytes) transfered by a network device. So let's do just
+that next. We will start with a description of how to collect data.
+
+Some people will make a remark that there are tools which can do this data
+collection for you. They are right! However, I feel it is important that
+you understand they are not necessary. When you have to determine why
+things went wrong you need to know how they work.
+
+One tool used in the example has been talked about very briefly in the
+beginning of this document, it is called SNMP. It is a way of talking
+to networked equipment. The tool I use below is called "snmpget" and
+this is how it works:
+
+   snmpget device password OID
+
+or
+
+   snmpget -v[version] -c[password] device OID
+
+For device you substitute the name, or the IP address, of your device.
+For password you use the "community read string" as it is called in the
+SNMP world.  For some devices the default of "public" might work, however
+this can be disabled, altered or protected for privacy and security
+reasons.  Read the documentation that comes with your device or program.
+
+Then there is this parameter, called OID, which means "object identifier".
+
+When you start to learn about SNMP it looks very confusing. It isn't
+all that difficult when you look at the Management Information Base
+("MIB").  It is an upside-down tree that describes data, with a single node
+as the root and from there a number of branches.  These branches end
+up in another node, they branch out, etc.  All the branches have a name
+and they form the path that we follow all the way down.  The branches
+that we follow are named: iso, org, dod, internet, mgmt and mib-2.
+These names can also be written down as numbers and are 1 3 6 1 2 1.
+
+   iso.org.dod.internet.mgmt.mib-2 (1.3.6.1.2.1)
+
+There is a lot of confusion about the leading dot that some programs
+use.  There is *no* leading dot in an OID.  However, some programs
+can use the above part of OIDs as a default.  To indicate the difference
+between abbreviated OIDs and full OIDs they need a leading dot when
+you specify the complete OID.  Often those programs will leave out
+the default portion when returning the data to you.  To make things
+worse, they have several default prefixes ...
+
+Ok, lets continue to the start of our OID: we had 1.3.6.1.2.1
+From there, we are especially interested in the branch "interfaces"
+which has number 2 (e.g., 1.3.6.1.2.1.2 or 1.3.6.1.2.1.interfaces).
+
+First, we have to get some SNMP program. First look if there is a
+pre-compiled package available for your OS. This is the preferred way.
+If not, you will have to get the sources yourself and compile those.
+The Internet is full of sources, programs etc. Find information using
+a search engine or whatever you prefer.
+
+Assume you got the program. First try to collect some data that is
+available on most systems. Remember: there is a short name for the
+part of the tree that interests us most in the world we live in!
+
+I will give an example which can be used on Fedora Core 3.  If it
+doesn't work for you, work your way through the manual of snmp and
+adapt the example to make it work.
+
+   snmpget -v2c -c public myrouter system.sysDescr.0
+
+The device should answer with a description of itself, perhaps an
+empty one. Until you got a valid answer from a device, perhaps using a
+different "password", or a different device, there is no point in
+continuing.
+
+   snmpget -v2c -c public myrouter interfaces.ifNumber.0
+
+Hopefully you get a number as a result, the number of interfaces.
+If so, you can carry on and try a different program called "snmpwalk".
+
+   snmpwalk -v2c -c public myrouter interfaces.ifTable.ifEntry.ifDescr
+
+If it returns with a list of interfaces, you're almost there.
+Here's an example:
+   [user@host /home/alex]$ snmpwalk -v2c -c public cisco 2.2.1.2
+
+   interfaces.ifTable.ifEntry.ifDescr.1 = "BRI0: B-Channel 1"
+   interfaces.ifTable.ifEntry.ifDescr.2 = "BRI0: B-Channel 2"
+   interfaces.ifTable.ifEntry.ifDescr.3 = "BRI0" Hex: 42 52 49 30
+   interfaces.ifTable.ifEntry.ifDescr.4 = "Ethernet0"
+   interfaces.ifTable.ifEntry.ifDescr.5 = "Loopback0"
+
+On this cisco equipment, I would like to monitor the "Ethernet0"
+interface and from the above output I see that it is number four. I try:
+
+   [user@host /home/alex]$ snmpget -v2c -c public cisco 2.2.1.10.4 2.2.1.16.4
+
+   interfaces.ifTable.ifEntry.ifInOctets.4 = 2290729126
+   interfaces.ifTable.ifEntry.ifOutOctets.4 = 1256486519
+
+So now I have two OIDs to monitor and they are (in full, this time):
+
+   1.3.6.1.2.1.2.2.1.10
+
+and
+
+   1.3.6.1.2.1.2.2.1.16
+
+both with an interface number of 4.
+
+Don't get fooled, this wasn't my first try. It took some time for me too
+to understand what all these numbers mean. It does help a lot when they
+get translated into descriptive text... At least, when people are talking
+about MIBs and OIDs you know what it's all about.
+Do not forget the interface number (0 if it is not interface dependent)
+and try snmpwalk if you don't get an answer from snmpget.
+
+If you understand the above section and get numbers from your device, continue
+on with this tutorial. If not, then go back and re-read this part.
+
+=head2 A Real World Example
+
+Let the fun begin. First, create a new database. It contains data from
+two counters, called input and output. The data is put into archives
+that average it. They take 1, 6, 24 or 288 samples at a time.
+They also go into archives that keep the maximum numbers. This will be
+explained later on. The time in-between samples is 300 seconds, a good
+starting point, which is the same as five minutes.
+
+ 1 sample "averaged" stays 1 period of 5 minutes
+ 6 samples averaged become one average on 30 minutes
+ 24 samples averaged become one average on 2 hours
+ 288 samples averaged become one average on 1 day
+
+Lets try to be compatible with MRTG which stores about the following
+amount of data:
+
+ 600 5-minute samples:    2   days and 2 hours
+ 600 30-minute samples:  12.5 days
+ 600 2-hour samples:     50   days
+ 732 1-day samples:     732   days
+
+These ranges are appended, so the total amount of data stored in the
+database is approximately 797 days. RRDtool stores the data
+differently, it doesn't start the "weekly" archive where the "daily"
+archive stopped. For both archives the most recent data will be near
+"now" and therefore we will need to keep more data than MRTG does!
+
+We will need:
+
+ 600 samples of 5 minutes  (2 days and 2 hours)
+ 700 samples of 30 minutes (2 days and 2 hours, plus 12.5 days)
+ 775 samples of 2 hours    (above + 50 days)
+ 797 samples of 1 day      (above + 732 days, rounded up to 797)
+
+   rrdtool create myrouter.rrd         \
+            DS:input:COUNTER:600:U:U   \
+            DS:output:COUNTER:600:U:U  \
+            RRA:AVERAGE:0.5:1:600      \
+            RRA:AVERAGE:0.5:6:700      \
+            RRA:AVERAGE:0.5:24:775     \
+            RRA:AVERAGE:0.5:288:797    \
+            RRA:MAX:0.5:1:600          \
+            RRA:MAX:0.5:6:700          \
+            RRA:MAX:0.5:24:775         \
+            RRA:MAX:0.5:288:797
+
+Next thing to do is to collect data and store it. Here is an example.
+It is written partially in pseudo code,  you will have to find out what
+to do exactly on your OS to make it work.
+
+   while not the end of the universe
+   do
+      get result of
+         snmpget router community 2.2.1.10.4
+      into variable $in
+      get result of
+         snmpget router community 2.2.1.16.4
+      into variable $out
+
+      rrdtool update myrouter.rrd N:$in:$out
+
+      wait for 5 minutes
+   done
+
+Then, after collecting data for a day, try to create an image using:
+
+   rrdtool graph myrouter-day.png --start -86400 \
+            DEF:inoctets=myrouter.rrd:input:AVERAGE \
+            DEF:outoctets=myrouter.rrd:output:AVERAGE \
+            AREA:inoctets#00FF00:"In traffic" \
+            LINE1:outoctets#0000FF:"Out traffic"
+
+This should produce a picture with one day worth of traffic.
+One day is 24 hours of 60 minutes of 60 seconds: 24*60*60=86'400, we
+start at now minus 86'400 seconds. We define (with DEFs) inoctets and
+outoctets as the average values from the database myrouter.rrd and draw
+an area for the "in" traffic and a line for the "out" traffic.
+
+View the image and keep logging data for a few more days.
+If you like, you could try the examples from the test database and
+see if you can get various options and calculations to work.
+
+Suggestion: Display in bytes per second and in bits per second. Make
+the Ethernet graphics go red if they are over four megabits per
+second.
+
+=head2 Consolidation Functions
+
+A few paragraphs back I mentioned the possibility of keeping
+the maximum values instead of the average values. Let's go
+into this a bit more.
+
+Recall all the stuff about the speed of the car. Suppose we drove at 144
+KM/H during 5 minutes and then were stopped by the police for 25 minutes.
+At the end of the lecture we would take our laptop and create and view the
+image taken from the database. If we look at the second RRA we did
+create, we would have the average from 6 samples. The samples measured
+would be 144+0+0+0+0+0=144, divided by 30 minutes, corrected for the
+error by 1000, translated into KM/H, with a result of 24 KM/H.
+I would still get a ticket but not for speeding anymore :)
+
+Obviously, in this case we shouldn't look at the averages. In some
+cases they are handy. If you want to know how many KM you had traveled,
+the averaged picture would be the right one to look at. On the other hand, for
+the speed that we traveled at, the maximum numbers seen is much more
+interesting. Later we will see more types.
+
+It is the same for data. If you want to know the amount, look at the
+averages. If you want to know the rate, look at the maximum.
+Over time, they will grow apart more and more. In the last database
+we have created, there are two archives that keep data per day. The
+archive that keeps averages will show low numbers, the archive that
+shows maxima will have higher numbers.
+
+For my car this would translate in averages per day of 96/24=4 KM/H
+(as I travel about 94 kilometers on a day) during working days, and
+maxima of 120 KM/H (my top speed that I reach every day).
+
+Big difference. Do not look at the second graph to estimate the
+distances that I travel and do not look at the first graph to
+estimate my speed. This will work if the samples are close together,
+as they are in five minutes, but not if you average.
+
+On some days, I go for a long ride. If I go across Europe and travel
+for 12 hours, the first graph will rise to about 60 KM/H. The second
+one will show 180 KM/H. This means that I traveled a distance of 60
+KM/H times 24 H = 1440 KM. I did this with a higher speed and a
+maximum around 180 KM/H. However, it probably doesn't mean that I
+traveled for 8 hours at a constant speed of 180 KM/H!
+
+This is a real example: go with the flow through Germany (fast!) and stop
+a few times for gas and coffee. Drive slowly through Austria and the
+Netherlands. Be careful in the mountains and villages. If you would
+look at the graphs created from the five-minute averages you would
+get a totally different picture. You would see the same values on the
+average and maximum graphs (provided I measured every 300 seconds).
+You would be able to see when I stopped, when I was in top gear, when
+I drove over fast highways etc. The granularity of the data is much
+higher, so you can see more. However, this takes 12 samples per hour,
+or 288 values per day, so it would be a lot of data over a longer
+period of time. Therefore we average it, eventually to one value per
+day. From this one value, we cannot see much detail, of course.
+
+Make sure you understand the last few paragraphs. There is no value
+in only a line and a few axis, you need to know what they mean and
+interpret the data in ana appropriate way. This is true for all data.
+
+The biggest mistake you can make is to use the collected data for
+something that it is not suitable for. You would be better off if
+you didn't have the graph at all.
+
+
+=head2 Let's review what you now should know
+
+You know how to create a database and can put data in it. You can get
+the numbers out again by creating an image, do math on the data from
+the database and view the resulte instead of the raw data.  You know
+about the difference between averages and maxima, and when to use
+which (or at least you should have an idea).
+
+RRDtool can do more than what we have learned up to now. Before you
+continue with the rest of this doc, I recommend that you reread from
+the start and try some modifications on the examples. Make sure you
+fully understand everything. It will be worth the effort and helps
+you not only with the rest of this tutorial, but also in your day to day
+monitoring long after you read this introduction.
+
+=head2 Data Source Types
+
+All right, you feel like continuing. Welcome back and get ready
+for an increased speed in the examples and explanations.
+
+You know that in order to view a counter over time, you have to
+take two numbers and divide the difference of them between the
+time lapsed.  This makes sense for the examples I gave you but there
+are other possibilities.  For instance, I'm able to retrieve the
+temperature from my router in three places namely the inlet, the
+so called hot-spot and the exhaust.  These values are not counters.
+If I take the difference of the two samples and divide that by
+300 seconds I would be asking for the temperature change per second.
+Hopefully this is zero! If not, the computer room is probably on fire :)
+
+So, what can we do?  We can tell RRDtool to store the values we measure
+directly as they are (this is not entirely true but close enough). The
+graphs we make will look much better, they will show a rather constant
+value. I know when the router is busy (it
+works -> it uses more electricity -> it generates more heat -> the
+temperature rises). I know when the doors are left open (the room is
+air conditioned) -> the warm air from the rest of the building flows into the
+computer room -> the inlet temperature rises). Etc. The data type we
+use when creating the database before was counter, we now have a
+different data type and thus a different name for it. It is called
+GAUGE. There are more such data types:
+
+ - COUNTER   we already know this one
+ - GAUGE     we just learned this one
+ - DERIVE
+ - ABSOLUTE
+
+The two additional types are DERIVE and ABSOLUTE. Absolute can be used like
+counter with one difference: RRDtool assumes the counter is reset when
+it's read. That is: its delta is known without calculation by RRDtool
+whereas RRDtool needs to calculate it for the counter type.
+Example: our first example (12'345, 12'357, 12'363, 12'363) would read:
+unknown, 12, 6, 0. The rest of the calculations stay the same.
+The other one, derive, is like counter. Unlike counter, it can also
+decrease so it can have a negative delta. Again, the rest of the
+calculations stay the same.
+
+Let's try them all:
+
+   rrdtool create all.rrd --start 978300900 \

+=head2 RRDtool under the Microscope
+
+=over 2
+
+=item *
+
+Line A is a COUNTER type, so it should continuously increment and RRDtool
+must calculate the differences. Also, RRDtool needs to divide the
+difference by the amount of time lapsed. This should end up as a
+straight line at 1 (the deltas are 300, the time is 300).
+
+=item *
+
+Line B is of type GAUGE. These are "real" values so they should match
+what we put in: a sort of a wave.
+
+=item *
+
+Line C is of type DERIVE. It should be a counter that can decrease. It does
+so between 2'400 and 0, with 1'800 in-between.
+
+=item *
+
+Line D is of type ABSOLUTE. This is like counter but it works on
+values without calculating the difference. The numbers are the same
+and as you can see (hopefully) this has a different result.
+
+=back
+
+This translates in the following values, starting at 23:10 and ending
+at 00:10 the next day (where "u" means unknown/unplotted):
+
+ - Line A:  u  u  1  1  1  1  1  1  1  1  1  u
+ - Line B:  u  1  3  5  3  1  2  4  6  4  2  u
+ - Line C:  u  u  2  2  2  0 -2 -6  2  0  2  u
+ - Line D:  u  1  2  3  4  5  6  7  8  9 10  u
+
+If your PNG shows all this, you know you have entered the data correctly,
+the RRDtool executable is working properly, your viewer doesn't fool you,
+and you successfully entered the year 2000 :)
+
+You could try the same example four times, each time with only one of
+the lines.
+
+Let's go over the data again:
+
+=over 2
+
+=item *
+
+Line A: 300,600,900 and so on. The counter delta is a constant 300 and
+so is the time delta. A number divided by itself is always 1 (except
+when dividing by zero which is undefined/illegal).
+
+Why is it that the first point is unknown? We do know what we put into
+the database, right? True, But we didn't have a value to calculate the delta
+from, so we don't know where we started. It would be wrong to assume we
+started at zero so we don't!
+
+=item *
+
+Line B: There is nothing to calculate. The numbers are as they are.
+
+=item *
+
+Line C: Again, the start-out value is unknown. The same story is holds
+as for line A. In this case the deltas are not constant, therefore the line
+is not either. If we would put the same numbers in the database as we did for
+line A, we would have gotten the same line. Unlike type counter,
+this type can decrease and I hope to show you later on why
+this makes a difference.
+
+=item *
+
+Line D: Here the device calculates the deltas. Therefore we DO know the
+first delta and it is plotted. We had the same input as with line A, but
+the meaning of this input is different and thus the line is different.
+In this case the deltas increase each time with 300. The time delta
+stays at a constant 300 and therefore the division of the two gives
+increasing values.
+
+=back
+
+=head2 Counter Wraps
+
+There are a few more basics to show. Some important options are still to
+be covered and we haven't look at counter wraps yet. First the counter wrap:
+In our car we notice that the counter shows 999'987. We travel 20 KM and
+the counter should go to 1'000'007. Unfortunately, there are only six digits
+on our counter so it really shows 000'007. If we would plot that on a type
+DERIVE, it would mean that the counter was set back 999'980 KM. It wasn't,
+and there has to be some protection for this. This protection is only
+available for type COUNTER which should be used for this kind of counter
+anyways. How does it work? Type counter should never decrease and
+therefore RRDtool must assume it wrapped if it does decrease!
+If the delta is negative, this can be compensated for by adding the
+maximum value of the counter + 1. For our car this would be:
+
+ Delta = 7 - 999'987 = -999'980    (instead of 1'000'007-999'987=20)
+
+ Real delta = -999'980 + 999'999 + 1 = 20
+
+At the time of writing this document, RRDtool knows of counters that
+are either 32 bits or 64 bits of size. These counters can handle the
+following different values:
+
+ - 32 bits: 0 ..           4'294'967'295
+ - 64 bits: 0 .. 18'446'744'073'709'551'615
+
+If these numbers look strange to you, you can view them in
+their hexadecimal form:
+
+ - 32 bits: 0 ..         FFFFFFFF
+ - 64 bits: 0 .. FFFFFFFFFFFFFFFF
+
+RRDtool handles both counters the same. If an overflow occurs and
+the delta would be negative, RRDtool first adds the maximum of a small
+counter + 1 to the delta. If the delta is still negative, it had to be
+the large counter that wrapped. Add the maximum possible value of the
+large counter + 1 and subtract the erroneously added small value.
+
+There is a risk in this: suppose the large counter wrapped while adding
+a huge delta, it could happen, theoretically, that adding the smaller value
+would make the delta positive. In this unlikely case the results would
+not be correct. The increase should be nearly as high as the maximum
+counter value for that to happen, so chances are you would have several
+other problems as well and this particular problem would not even be
+worth thinking about. Even though, I did include an example, so you
+can judge for yourself.
+
+The next section gives you some numerical examples for counter-wraps.
+Try to do the calculations yourself or just believe me if your calculator
+can't handle the numbers :)

+
+As you can see from the last two examples, you need strange numbers
+for RRDtool to fail (provided it's bug free of course), so this should
+not happen. However, SNMP or whatever method you choose to collect the
+data, might also report wrong numbers occasionally.  We can't prevent all
+errors, but there are some things we can do. The RRDtool "create" command
+takes two special parameters for this. They define
+the minimum and maximum allowed values. Until now, we used "U", meaning
+"unknown". If you provide values for one or both of them and if RRDtool
+receives data points that are outside these limits, it will ignore those
+values. For a thermometer in degrees Celsius, the absolute minimum is
+just under -273. For my router, I can assume this minimum is much higher
+so I would set it to 10, where as the maximum temperature I would
+set to 80. Any higher and the device would be out of order.
+
+For the speed of my car, I would never expect negative numbers and
+also I would not expect a speed  higher than 230. Anything else,
+and there must have been an error. Remember: the opposite is not true,
+if the numbers pass this check, it doesn't mean that they are
+correct. Always judge the graph with a healthy dose of suspicion if it
+seems weird to you.
+
+=head2 Data Resampling
+
+One important feature of RRDtool has not been explained yet: it is
+virtually impossible to collect data and feed it into RRDtool on exact
+intervals. RRDtool therefore interpolates the data, so they are stored
+on exact intervals. If you do not know what this means or how it
+works, then here's the help you seek:
+
+Suppose a counter increases by exactly one for every second. You want
+to measure it in 300 seconds intervals. You should retrieve values
+that are exactly 300 apart. However, due to various circumstances you
+are a few seconds late and the interval is 303. The delta will also be
+303 in that case. Obviously, RRDtool should not put 303 in the database
+and make you believe that the counter increased by 303 in 300 seconds.
+This is where RRDtool interpolates: it alters the 303 value as if it
+would have been stored earlier and it will be 300 in 300 seconds.
+Next time you are at exactly the right time. This means that the current
+interval is 297 seconds and also the counter increased by 297. Again,
+RRDtool interpolates and stores 300 as it should be.
+
+      in the RRD                 in reality
+
+ time+000:   0 delta="U"   time+000:    0 delta="U"
+ time+300: 300 delta=300   time+300:  300 delta=300
+ time+600: 600 delta=300   time+603:  603 delta=303
+ time+900: 900 delta=300   time+900:  900 delta=297
+
+Let's create two identical databases. I've chosen the time range 920'805'000
+to 920'805'900 as this goes very well with the example numbers.
+
+   rrdtool create seconds1.rrd   \
+      --start 920804700          \
+      DS:seconds:COUNTER:600:U:U \
+      RRA:AVERAGE:0.5:1:24
+
+Make a copy
+
+   for Unix: cp seconds1.rrd seconds2.rrd
+   for Dos:  copy seconds1.rrd seconds2.rrd
+   for vms:  how would I know :)
+
+Put in some data
+
+   rrdtool update seconds1.rrd \
+      920805000:000 920805300:300 920805600:600 920805900:900

+View both images together (add them to your index.html file)

+
+=head1 WRAPUP
+
+It's time now to wrap up this tutorial. We covered all the basics for
+you to be able to work with RRDtool and to read the additional
+documentation available. There is plenty more to discover about
+RRDtool and you will find more and more uses for this package. You can
+easly create graphs using just the examples provided and using only
+RRDtool. You can also use one of the front ends to RRDtool that are
+available.
+
+=head1 MAILINGLIST
+
+Remember to subscribe to the RRDtool mailing list. Even if you are not
+answering to mails that come by, it helps both you and the rest of the
+users. A lot of the stuff that I know about MRTG (and therefore about
+RRDtool) I've learned while just reading the list without posting to
+it. I did not need to ask the basic questions as they are answered in
+the FAQ (read it!) and in various mails by other users. With
+thousands of users all over the world, there will always be people who
+ask questions that you can answer because you read this and other
+documentation and they didn't.

+
+I hope you enjoyed the examples and their descriptions. If you do, help
+other people by pointing them to this document when they are asking
+basic questions. They will not only get their answers, but at the same
+time learn a whole lot more.

+
+D\bDE\bES\bSC\bCR\bRI\bIP\bPT\bTI\bIO\bON\bN
+       RRDtool is written by Tobias Oetiker <tobi@oetiker.ch> with contribu-
+       tions from many people all around the world. This document is written
+       by Alex van den Bogaerdt <alex@ergens.op.het.net> to help you under-
+       stand what RRDtool is and what it can do for you.
+
+       The documentation provided with RRDtool can be too technical for some
+       people. This tutorial is here to help you understand the basics of RRD-
+       tool. It should prepare you to read the documentation yourself.  It
+       also explains the general things about statistics with a focus on net-
+       working.

+
+       Please don't skip ahead in this document!  The first part of this docu-
+       ment explains the basics and may be boring.  But if you don't under-
+       stand the basics, the examples will not be as meaningful to you.

+
+       RRDtool refers to Round Robin Database tool.  Round robin is a tech-
+       nique that works with a fixed amount of data, and a pointer to the cur-
+       rent element. Think of a circle with some dots plotted on the edge --
+       these dots are the places where data can be stored. Draw an arrow from
+       the center of the circle to one of the dots -- this is the pointer.
+       When the current data is read or written, the pointer moves to the next
+       element. As we are on a circle there is neither a beginning nor an end,
+       you can go on and on and on. After a while, all the available places
+       will be used and the process automatically reuses old locations. This
+       way, the dataset will not grow in size and therefore requires no main-
+       tenance.  RRDtool works with with Round Robin Databases (RRDs). It
+       stores and retrieves data from them.

+
+       You name it, it will probably fit as long as it is some sort of time-
+       series data. This means you have to be able to measure some value at
+       several points in time and provide this information to RRDtool. If you
+       can do this, RRDtool will be able to store it. The values must be
+       numerical but don't have to be integers, as is the case with MRTG (the
+       next section will give more details on this more specialized applica-
+       tion).
+
+       Many examples below talk about SNMP which is an acronym for Simple Net-
+       work Management Protocol. "Simple" refers to the protocol -- it does
+       not mean it is simple to manage or monitor a network. After working
+       your way through this document, you should know enough to be able to
+       understand what people are talking about. For now, just realize that
+       SNMP can be used to query devices for the values of counters they keep.
+       It is the value from those counters that we want to store in the RRD.

+
+       RRDtool originated from MRTG (Multi Router Traffic Grapher). MRTG
+       started as a tiny little script for graphing the use of a university's
+       connection to the Internet. MRTG was later (ab-)used as a tool for
+       graphing other data sources including temperature, speed, voltage, num-
+       ber of printouts and the like.
+
+       Most likely you will start to use RRDtool to store and process data
+       collected via SNMP. The data will most likely be bytes (or bits) trans-
+       fered from and to a network or a computer.  But it can also be used to
+       display tidal waves, solar radiation, power consumption, number of vis-
+       itors at an exhibition, noise levels near an airport, temperature on
+       your favorite holiday location, temperature in the fridge and whatever
+       you imagination can come up with.
+
+       You only need a sensor to measure the data and be able to feed the num-
+       bers into RRDtool. RRDtool then lets you create a database, store data
+       in it, retrieve that data and create graphs in PNG format for display
+       on a web browser. Those PNG images are dependent on the data you col-
+       lected and could be, for instance, an overview of the average network
+       usage, or the peaks that occurred.

+
+       First of all: read it again! You may have missed something.  If you are
+       unable to compile the sources and you have a fairly common OS, it will
+       probably not be the fault of RRDtool. There may be pre-compiled ver-
+       sions around on the Internet. If they come from trusted sources, get
+       one of those.
+
+       If on the other hand the program works but does not give you the
+       expected results, it will be a problem with configuring it. Review your
+       configuration and compare it with the examples that follow.
+
+       There is a mailing list and an archive of it. Read the list for a few
+       weeks and search the archive. It is considered rude to just ask a ques-
+       tion without searching the archives: your problem may already have been
+       solved for somebody else!  This is true for most, if not all, mailing
+       lists and not only for this particular one. Look in the documentation
+       that came with RRDtool for the location and usage of the list.
+
+       I suggest you take a moment to subscribe to the mailing list right now
+       by sending an email to <rrd-users-request@lists.oetiker.ch> with a sub-
+       ject of "subscribe". If you ever want to leave this list, just write an
+       email to the same address but now with a subject of "unsubscribe".

+
+       By giving you some detailed descriptions with detailed examples.  I
+       assume that following the instructions in the order presented will give
+       you enough knowledge of RRDtool to experiment for yourself.  If it
+       doesn't work the first time, don't give up. Reread the stuff that you
+       did understand, you may have missed something.
+
+       By following the examples you get some hands-on experience and, even
+       more important, some background information of how it works.
+
+       You will need to know something about hexadecimal numbers. If you don't
+       then start with reading bin_dec_hex before you continue here.

+
+       In my opinion the best way to learn something is to actually do it.
+       Why not start right now?  We will create a database, put some values in
+       it and extract this data again.  Your output should be the same as the
+       output that is included in this document.
+
+       We will start with some easy stuff and compare a car with a router, or
+       compare kilometers (miles if you wish) with bits and bytes. It's all
+       the same: some number over some time.
+
+       Assume we have a device that transfers bytes to and from the Internet.
+       This device keeps a counter that starts at zero when it is turned on,
+       increasing with every byte that is transfered. This counter will proba-
+       bly have a maximum value. If this value is reached and an extra byte is
+       counted, the counter starts over at zero. This is the same as many
+       counters in the world such as the mileage counter in a car.
+
+       Most discussions about networking talk about bits per second so lets
+       get used to that right away. Assume a byte is eight bits and start to
+       think in bits not bytes. The counter, however, still counts bytes!  In
+       the SNMP world most of the counters are 32 bits. That means they are
+       counting from 0 to 4'294'967'295. We will use these values in the exam-
+       ples.  The device, when asked, returns the current value of the
+       counter. We know the time that has passes since we last asked so we now
+       know how many bytes have been transfered ***on average*** per second.
+       This is not very hard to calculate. First in words, then in calcula-
+       tions:
+
+       1. Take the current counter, subtract the previous value from it.
+
+       2. Do the same with the current time and the previous time (in sec-
+          onds).
+
+       3. Divide the outcome of (1) by the outcome of (2), the result is the
+          amount of bytes per second. Multiply by eight to get the number of
+          bits per second (bps).
+
+         bps = (counter_now - counter_before) / (time_now - time_before) * 8
+
+       For some people it may help to translate this to an automobile example.
+       Do not try this example, and if you do, don't blame me for the results!
+
+       People who are not used to think in kilometers per hour can translate
+       most into miles per hour by dividing km by 1.6 (close enough).  I will
+       use the following abbreviations:
+
+        M:    meter
+        KM:   kilometer (= 1'000 meters).
+        H:    hour
+        S:    second
+        KM/H: kilometers per hour
+        M/S:  meters per second
+
+       You are driving a car. At 12:05 you read the counter in the dashboard
+       and it tells you that the car has moved 12'345 KM until that moment.
+       At 12:10 you look again, it reads 12'357 KM. This means you have trav-
+       eled 12 KM in five minutes. A scientist would translate that into
+       meters per second and this makes a nice comparison toward the problem
+       of (bytes per five minutes) versus (bits per second).
+
+       We traveled 12 kilometers which is 12'000 meters. We did that in five
+       minutes or 300 seconds. Our speed is 12'000M / 300S or 40 M/S.
+
+       We could also calculate the speed in KM/H: 12 times 5 minutes is an
+       hour, so we have to multiply 12 KM by 12 to get 144 KM/H.  For our
+       native English speaking friends: that's 90 MPH so don't try this exam-
+       ple at home or where I live :)
+
+       Remember: these numbers are averages only.  There is no way to figure
+       out from the numbers, if you drove at a constant speed.  There is an
+       example later on in this tutorial that explains this.
+
+       I hope you understand that there is no difference in calculating M/S or
+       bps; only the way we collect the data is different. Even the K from
+       kilo is the same as in networking terms k also means 1'000.
+
+       We will now create a database where we can keep all these interesting
+       numbers. The method used to start the program may differ slightly from
+       OS to OS, but I assume you can figure it out if it works different on
+       your's. Make sure you do not overwrite any file on your system when
+       executing the following command and type the whole line as one long
+       line (I had to split it for readability) and skip all of the '\' char-
+       acters.
+
+          rrdtool create test.rrd             \
+                   --start 920804400          \
+                   DS:speed:COUNTER:600:U:U   \
+                   RRA:AVERAGE:0.5:1:24       \
+                   RRA:AVERAGE:0.5:6:10
+
+       (So enter: "rrdtool create test.rrd --start 920804400 DS ...")
+
+       W\bWh\bha\bat\bt h\bha\bas\bs b\bbe\bee\ben\bn c\bcr\bre\bea\bat\bte\bed\bd?\b?
+
+       We created the round robin database called test (test.rrd) which starts
+       at noon the day I started writing this document, 7th of March, 1999
+       (this date translates to 920'804'400 seconds as explained below). Our
+       database holds one data source (DS) named "speed" that represents a
+       counter. This counter is read every five minutes (this is the default
+       therefore you don't have to put "--step=300").  In the same database
+       two round robin archives (RRAs) are kept, one averages the data every
+       time it is read (e.g., there's nothing to average) and keeps 24 samples
+       (24 times 5 minutes is 2 hours). The other averages 6 values (half
+       hour) and contains 10 such averages (e.g. 5 hours).
+
+       RRDtool works with special time stamps coming from the UNIX world.
+       This time stamp is the number of seconds that passed since January 1st
+       1970 UTC.  The time stamp value is translated into local time and it
+       will therefore look different for different time zones.
+
+       Chances are that you are not in the same part of the world as I am.
+       This means your time zone is different. In all examples where I talk
+       about time, the hours may be wrong for you. This has little effect on
+       the results of the examples, just correct the hours while reading.  As
+       an example: where I will see "12:05" the UK folks will see "11:05".
+
+       We now have to fill our database with some numbers. We'll pretend to
+       have read the following numbers:
+
+        12:05  12345 KM
+        12:10  12357 KM
+        12:15  12363 KM
+        12:20  12363 KM
+        12:25  12363 KM
+        12:30  12373 KM
+        12:35  12383 KM
+        12:40  12393 KM
+        12:45  12399 KM
+        12:50  12405 KM
+        12:55  12411 KM
+        13:00  12415 KM
+        13:05  12420 KM
+        13:10  12422 KM
+        13:15  12423 KM
+
+       We fill the database as follows:
+
+        rrdtool update test.rrd 920804700:12345 920805000:12357 920805300:12363
+        rrdtool update test.rrd 920805600:12363 920805900:12363 920806200:12373
+        rrdtool update test.rrd 920806500:12383 920806800:12393 920807100:12399
+        rrdtool update test.rrd 920807400:12405 920807700:12411 920808000:12415
+        rrdtool update test.rrd 920808300:12420 920808600:12422 920808900:12423
+
+       This reads: update our test database with the following numbers
+
+        time 920804700, value 12345
+        time 920805000, value 12357
+
+       etcetera.
+
+       As you can see, it is possible to feed more than one value into the
+       database in one command. I had to stop at three for readability but the
+       real maximum per line is OS dependent.
+
+       We can now retrieve the data from our database using "rrdtool fetch":
+
+        rrdtool fetch test.rrd AVERAGE --start 920804400 --end 920809200
+
+       It should return the following output:
+
+                                 speed
+

+
+       If it doesn't, something may be wrong.  Perhaps your OS will print
+       "NaN" in a different form. "NaN" stands for "Not A Number".  If your OS
+       writes "U" or "UNKN" or something similar that's okay.  If something
+       else is wrong, it will probably be due to an error you made (assuming
+       that my tutorial is correct of course :-). In that case: delete the
+       database and try again.  Sometimes things change.  This example used to
+       provide numbers like "0.04" in stead of "4.00000e-02".  Those are
+       really the same numbers, just written down differently.  Don't be
+       alarmed if a future version of rrdtool displays a slightly different
+       form of output. The examples in this document are correct for version
+       1.2.0 of RRDtool.
+
+       The meaning of the above output will become clear below.

+
+       Try the following command:
+
+        rrdtool graph speed.png                                 \
+                --start 920804400 --end 920808000               \
+                DEF:myspeed=test.rrd:speed:AVERAGE              \
+                LINE2:myspeed#FF0000
+
+       This will create speed.png which starts at 12:00 and ends at 13:00.
+       There is a definition of a variable called myspeed, using the data from
+       RRA "speed" out of database "test.rrd". The line drawn is 2 pixels high
+       and represents the variable myspeed. The color is red (specified by its
+       rgb-representation, see below).
+
+       You'll notice that the start of the graph is not at 12:00 but at 12:05.
+       This is because we have insufficient data to tell the average before
+       that time. This will only happen when you miss some samples, this will
+       not happen a lot, hopefully.
+
+       If this has worked: congratulations! If not, check what went wrong.
+
+       The colors are built up from red, green and blue. For each of the com-
+       ponents, you specify how much to use in hexadecimal where 00 means not
+       included and FF means fully included.  The "color" white is a mixture
+       of red, green and blue: FFFFFF The "color" black is all colors off:
+       000000
+
+          red     #FF0000
+          green   #00FF00
+          blue    #0000FF
+          magenta #FF00FF     (mixed red with blue)
+          gray    #555555     (one third of all components)
+
+       Additionally you can add an alpha channel (transparency).  The default
+       will be "FF" which means non-transparent.
+
+       The PNG you just created can be displayed using your favorite image
+       viewer.  Web browsers will display the PNG via the URL
+       "file:///the/path/to/speed.png"

+
+       When looking at the image, you notice that the horizontal axis is
+       labeled 12:10, 12:20, 12:30, 12:40 and 12:50. Sometimes a label doesn't
+       fit (12:00 and 13:00 would be candidates) so they are skipped.
+
+       The vertical axis displays the range we entered. We provided kilometers
+       and when divided by 300 seconds, we get very small numbers. To be
+       exact, the first value was 12 (12'357-12'345) and divided by 300 this
+       makes 0.04, which is displayed by RRDtool as "40 m" meaning "40/1'000".
+       The "m" (milli) has nothing to do with meters, kilometers or millime-
+       ters! RRDtool doesn't know about the physical units of our data, it
+       just works with dimensionless numbers.
+
+       If we had measured our distances in meters, this would have been
+       (12'357'000-12'345'000)/300 = 12'000/300 = 40.
+
+       As most people have a better feel for numbers in this range, we'll cor-
+       rect that. We could recreate our database and store the correct data,
+       but there is a better way: we do some calculations while creating the
+       png file!
+
+          rrdtool graph speed2.png                           \
+             --start 920804400 --end 920808000               \
+             --vertical-label m/s                            \
+             DEF:myspeed=test.rrd:speed:AVERAGE              \
+             CDEF:realspeed=myspeed,1000,\*                  \
+             LINE2:realspeed#FF0000
+
+       Note: Make sure not to forget the backslash \ in front of the multipli-
+       cation operator * above. The backslash is needed to "escape" the * as
+       some operating systems might interpret and expand * instead of passing
+       it to the rrdtool command.
+
+       After viewing this PNG, you notice the "m" (milli) has disappeared.
+       This it what the correct result would be. Also, a label has been added
+       to the image.  Apart from the things mentioned above, the PNG should
+       look the same.
+
+       The calculations are specified in the CDEF part above and are in
+       Reverse Polish Notation ("RPN"). What we requested RRDtool to do is:
+       "take the data source myspeed and the number 1000; multiply those".
+       Don't bother with RPN yet, it will be explained later on in more
+       detail. Also, you may want to read my tutorial on CDEFs and Steve
+       Rader's tutorial on RPN. But first finish this tutorial.
+
+       Hang on! If we can multiply values with 1'000, it should also be possi-
+       ble to display kilometers per hour from the same data!
+
+       To change a value that is measured in meters per second:
+
+        Calculate meters per hour:     value * 3'600
+        Calculate kilometers per hour: value / 1'000
+        Together this makes:           value * (3'600/1'000) or value * 3.6
+
+       In our example database we made a mistake and we need to compensate for
+       this by multiplying with 1'000. Applying that correction:
+
+        value * 3.6  * 1'000 == value * 3'600
+
+       Now let's create this PNG, and add some more magic ...
+
+        rrdtool graph speed3.png                             \
+             --start 920804400 --end 920808000               \
+             --vertical-label km/h                           \
+             DEF:myspeed=test.rrd:speed:AVERAGE              \
+             "CDEF:kmh=myspeed,3600,*"                       \
+             CDEF:fast=kmh,100,GT,kmh,0,IF                   \
+             CDEF:good=kmh,100,GT,0,kmh,IF                   \
+             HRULE:100#0000FF:"Maximum allowed"              \
+             AREA:good#00FF00:"Good speed"                   \
+             AREA:fast#FF0000:"Too fast"
+
+       Note: here we use another means to escape the * operator by enclosing
+       the whole string in double quotes.
+
+       This graph looks much better. Speed is shown in KM/H and there is even
+       an extra line with the maximum allowed speed (on the road I travel on).
+       I also changed the colors used to display speed and changed it from a
+       line into an area.
+
+       The calculations are more complex now. For speed measurements within
+       the speed limit they are:
+
+          Check if kmh is greater than 100    ( kmh,100 ) GT
+          If so, return 0, else kmh           ((( kmh,100 ) GT ), 0, kmh) IF
+
+       For values above the speed limit:
+
+          Check if kmh is greater than 100    ( kmh,100 ) GT
+          If so, return kmh, else return 0    ((( kmh,100) GT ), kmh, 0) IF
+
+       G\bGr\bra\bap\bph\bhi\bic\bcs\bs M\bMa\bag\bgi\bic\bc
+
+       I like to believe there are virtually no limits to how RRDtool graph
+       can manipulate data. I will not explain how it works, but look at the
+       following PNG:
+
+          rrdtool graph speed4.png                           \
+             --start 920804400 --end 920808000               \
+             --vertical-label km/h                           \
+             DEF:myspeed=test.rrd:speed:AVERAGE              \
+             "CDEF:kmh=myspeed,3600,*"                       \
+             CDEF:fast=kmh,100,GT,100,0,IF                   \
+             CDEF:over=kmh,100,GT,kmh,100,-,0,IF             \
+             CDEF:good=kmh,100,GT,0,kmh,IF                   \
+             HRULE:100#0000FF:"Maximum allowed"              \
+             AREA:good#00FF00:"Good speed"                   \
+             AREA:fast#550000:"Too fast"                     \
+             STACK:over#FF0000:"Over speed"
+
+       Let's create a quick and dirty HTML page to view the three PNGs:
+
+          <HTML><HEAD><TITLE>Speed</TITLE></HEAD><BODY>
+          <IMG src="speed2.png" alt="Speed in meters per second">
+          <BR>
+          <IMG src="speed3.png" alt="Speed in kilometers per hour">
+          <BR>
+          <IMG src="speed4.png" alt="Traveled too fast?">
+          </BODY></HTML>
+
+       Name the file "speed.html" or similar, and look at it in your web
+       browser.
+
+       Now, all you have to do is measure the values regularly and update the
+       database.  When you want to view the data, recreate the PNGs and make
+       sure to refresh them in your browser. (Note: just clicking reload may
+       not be enough, especially when proxies are involved.  Try shift-reload
+       or ctrl-F5).

+
+       We've already used the "update" command: it took one or more parameters
+       in the form of "<time>:<value>". You'll be glad to know that you can
+       specify the current time by filling in a "N" as the time.  Or you could
+       use the "time" function in Perl (the shortest example in this tuto-
+       rial):
+
+          perl -e 'print time, "\n" '
+
+       How to run a program on regular intervals is OS specific. But here is
+       an example in pseudo code:
+
+          - Get the value and put it in variable "$speed"
+          - rrdtool update speed.rrd N:$speed
+
+       (do not try this with our test database, we'll use it in further exam-
+       ples)
+
+       This is all. Run the above script every five minutes. When you need to
+       know what the graphs look like, run the examples above. You could put
+       them in a script as well. After running that script, view the page
+       index.html we created above.

+
+       I can imagine very few people that will be able to get real data from
+       their car every five minutes. All other people will have to settle for
+       some other kind of counter. You could measure the number of pages
+       printed by a printer, for example, the cups of coffee made by the cof-
+       fee machine, a device that counts the electricity used, whatever. Any
+       incrementing counter can be monitored and graphed using the stuff you
+       learned so far. Later on we will also be able to monitor other types of
+       values like temperature.
+
+       Most (?) people interested in RRDtool will use the counter that keeps
+       track of octets (bytes) transfered by a network device. So let's do
+       just that next. We will start with a description of how to collect
+       data.
+
+       Some people will make a remark that there are tools which can do this
+       data collection for you. They are right! However, I feel it is impor-
+       tant that you understand they are not necessary. When you have to
+       determine why things went wrong you need to know how they work.
+
+       One tool used in the example has been talked about very briefly in the
+       beginning of this document, it is called SNMP. It is a way of talking
+       to networked equipment. The tool I use below is called "snmpget" and
+       this is how it works:
+
+          snmpget device password OID
+
+       or
+
+          snmpget -v[version] -c[password] device OID
+
+       For device you substitute the name, or the IP address, of your device.
+       For password you use the "community read string" as it is called in the
+       SNMP world.  For some devices the default of "public" might work, how-
+       ever this can be disabled, altered or protected for privacy and secu-
+       rity reasons.  Read the documentation that comes with your device or
+       program.
+
+       Then there is this parameter, called OID, which means "object identi-
+       fier".
+
+       When you start to learn about SNMP it looks very confusing. It isn't
+       all that difficult when you look at the Management Information Base
+       ("MIB").  It is an upside-down tree that describes data, with a single
+       node as the root and from there a number of branches.  These branches
+       end up in another node, they branch out, etc.  All the branches have a
+       name and they form the path that we follow all the way down.  The
+       branches that we follow are named: iso, org, dod, internet, mgmt and
+       mib-2.  These names can also be written down as numbers and are 1 3 6 1
+       2 1.
+
+          iso.org.dod.internet.mgmt.mib-2 (1.3.6.1.2.1)
+
+       There is a lot of confusion about the leading dot that some programs
+       use.  There is *no* leading dot in an OID.  However, some programs can
+       use the above part of OIDs as a default.  To indicate the difference
+       between abbreviated OIDs and full OIDs they need a leading dot when you
+       specify the complete OID.  Often those programs will leave out the
+       default portion when returning the data to you.  To make things worse,
+       they have several default prefixes ...
+
+       Ok, lets continue to the start of our OID: we had 1.3.6.1.2.1 From
+       there, we are especially interested in the branch "interfaces" which
+       has number 2 (e.g., 1.3.6.1.2.1.2 or 1.3.6.1.2.1.interfaces).
+
+       First, we have to get some SNMP program. First look if there is a pre-
+       compiled package available for your OS. This is the preferred way.  If
+       not, you will have to get the sources yourself and compile those.  The
+       Internet is full of sources, programs etc. Find information using a
+       search engine or whatever you prefer.
+
+       Assume you got the program. First try to collect some data that is
+       available on most systems. Remember: there is a short name for the part
+       of the tree that interests us most in the world we live in!
+
+       I will give an example which can be used on Fedora Core 3.  If it
+       doesn't work for you, work your way through the manual of snmp and
+       adapt the example to make it work.
+
+          snmpget -v2c -c public myrouter system.sysDescr.0
+
+       The device should answer with a description of itself, perhaps an empty
+       one. Until you got a valid answer from a device, perhaps using a dif-
+       ferent "password", or a different device, there is no point in
+       continuing.
+
+          snmpget -v2c -c public myrouter interfaces.ifNumber.0
+
+       Hopefully you get a number as a result, the number of interfaces.  If
+       so, you can carry on and try a different program called "snmpwalk".
+
+          snmpwalk -v2c -c public myrouter interfaces.ifTable.ifEntry.ifDescr
+
+       If it returns with a list of interfaces, you're almost there.  Here's
+       an example:
+          [user@host /home/alex]$ snmpwalk -v2c -c public cisco 2.2.1.2
+
+          interfaces.ifTable.ifEntry.ifDescr.1 = "BRI0: B-Channel 1"
+          interfaces.ifTable.ifEntry.ifDescr.2 = "BRI0: B-Channel 2"
+          interfaces.ifTable.ifEntry.ifDescr.3 = "BRI0" Hex: 42 52 49 30
+          interfaces.ifTable.ifEntry.ifDescr.4 = "Ethernet0"
+          interfaces.ifTable.ifEntry.ifDescr.5 = "Loopback0"
+
+       On this cisco equipment, I would like to monitor the "Ethernet0" inter-
+       face and from the above output I see that it is number four. I try:
+
+          [user@host /home/alex]$ snmpget -v2c -c public cisco 2.2.1.10.4 2.2.1.16.4
+
+          interfaces.ifTable.ifEntry.ifInOctets.4 = 2290729126
+          interfaces.ifTable.ifEntry.ifOutOctets.4 = 1256486519
+
+       So now I have two OIDs to monitor and they are (in full, this time):
+
+          1.3.6.1.2.1.2.2.1.10
+
+       and
+
+          1.3.6.1.2.1.2.2.1.16
+
+       both with an interface number of 4.
+
+       Don't get fooled, this wasn't my first try. It took some time for me
+       too to understand what all these numbers mean. It does help a lot when
+       they get translated into descriptive text... At least, when people are
+       talking about MIBs and OIDs you know what it's all about.  Do not for-
+       get the interface number (0 if it is not interface dependent) and try
+       snmpwalk if you don't get an answer from snmpget.
+
+       If you understand the above section and get numbers from your device,
+       continue on with this tutorial. If not, then go back and re-read this

+
+       Let the fun begin. First, create a new database. It contains data from
+       two counters, called input and output. The data is put into archives
+       that average it. They take 1, 6, 24 or 288 samples at a time.  They
+       also go into archives that keep the maximum numbers. This will be
+       explained later on. The time in-between samples is 300 seconds, a good
+       starting point, which is the same as five minutes.
+
+        1 sample "averaged" stays 1 period of 5 minutes
+        6 samples averaged become one average on 30 minutes
+        24 samples averaged become one average on 2 hours
+        288 samples averaged become one average on 1 day
+
+       Lets try to be compatible with MRTG which stores about the following
+       amount of data:
+
+        600 5-minute samples:    2   days and 2 hours
+        600 30-minute samples:  12.5 days
+        600 2-hour samples:     50   days
+        732 1-day samples:     732   days
+
+       These ranges are appended, so the total amount of data stored in the
+       database is approximately 797 days. RRDtool stores the data differ-
+       ently, it doesn't start the "weekly" archive where the "daily" archive
+       stopped. For both archives the most recent data will be near "now" and
+       therefore we will need to keep more data than MRTG does!
+
+       We will need:
+
+        600 samples of 5 minutes  (2 days and 2 hours)
+        700 samples of 30 minutes (2 days and 2 hours, plus 12.5 days)
+        775 samples of 2 hours    (above + 50 days)
+        797 samples of 1 day      (above + 732 days, rounded up to 797)
+
+          rrdtool create myrouter.rrd         \
+                   DS:input:COUNTER:600:U:U   \
+                   DS:output:COUNTER:600:U:U  \
+                   RRA:AVERAGE:0.5:1:600      \
+                   RRA:AVERAGE:0.5:6:700      \
+                   RRA:AVERAGE:0.5:24:775     \
+                   RRA:AVERAGE:0.5:288:797    \
+                   RRA:MAX:0.5:1:600          \
+                   RRA:MAX:0.5:6:700          \
+                   RRA:MAX:0.5:24:775         \
+                   RRA:MAX:0.5:288:797
+
+       Next thing to do is to collect data and store it. Here is an example.
+       It is written partially in pseudo code,  you will have to find out what
+       to do exactly on your OS to make it work.
+
+          while not the end of the universe
+          do
+             get result of
+                snmpget router community 2.2.1.10.4
+             into variable $in
+             get result of
+                snmpget router community 2.2.1.16.4
+             into variable $out
+
+             rrdtool update myrouter.rrd N:$in:$out
+
+             wait for 5 minutes
+          done
+
+       Then, after collecting data for a day, try to create an image using:
+
+          rrdtool graph myrouter-day.png --start -86400 \
+                   DEF:inoctets=myrouter.rrd:input:AVERAGE \
+                   DEF:outoctets=myrouter.rrd:output:AVERAGE \
+                   AREA:inoctets#00FF00:"In traffic" \
+                   LINE1:outoctets#0000FF:"Out traffic"
+
+       This should produce a picture with one day worth of traffic.  One day
+       is 24 hours of 60 minutes of 60 seconds: 24*60*60=86'400, we start at
+       now minus 86'400 seconds. We define (with DEFs) inoctets and outoctets
+       as the average values from the database myrouter.rrd and draw an area
+       for the "in" traffic and a line for the "out" traffic.
+
+       View the image and keep logging data for a few more days.  If you like,
+       you could try the examples from the test database and see if you can
+       get various options and calculations to work.
+
+       Suggestion: Display in bytes per second and in bits per second. Make
+       the Ethernet graphics go red if they are over four megabits per second.

+
+       A few paragraphs back I mentioned the possibility of keeping the maxi-
+       mum values instead of the average values. Let's go into this a bit
+       more.
+
+       Recall all the stuff about the speed of the car. Suppose we drove at
+       144 KM/H during 5 minutes and then were stopped by the police for 25
+       minutes.  At the end of the lecture we would take our laptop and create
+       and view the image taken from the database. If we look at the second
+       RRA we did create, we would have the average from 6 samples. The sam-
+       ples measured would be 144+0+0+0+0+0=144, divided by 30 minutes, cor-
+       rected for the error by 1000, translated into KM/H, with a result of 24
+       KM/H.  I would still get a ticket but not for speeding anymore :)
+
+       Obviously, in this case we shouldn't look at the averages. In some
+       cases they are handy. If you want to know how many KM you had traveled,
+       the averaged picture would be the right one to look at. On the other
+       hand, for the speed that we traveled at, the maximum numbers seen is
+       much more interesting. Later we will see more types.
+
+       It is the same for data. If you want to know the amount, look at the
+       averages. If you want to know the rate, look at the maximum.  Over
+       time, they will grow apart more and more. In the last database we have
+       created, there are two archives that keep data per day. The archive
+       that keeps averages will show low numbers, the archive that shows max-
+       ima will have higher numbers.
+
+       For my car this would translate in averages per day of 96/24=4 KM/H (as
+       I travel about 94 kilometers on a day) during working days, and maxima
+       of 120 KM/H (my top speed that I reach every day).
+
+       Big difference. Do not look at the second graph to estimate the dis-
+       tances that I travel and do not look at the first graph to estimate my
+       speed. This will work if the samples are close together, as they are in
+       five minutes, but not if you average.
+
+       On some days, I go for a long ride. If I go across Europe and travel
+       for 12 hours, the first graph will rise to about 60 KM/H. The second
+       one will show 180 KM/H. This means that I traveled a distance of 60
+       KM/H times 24 H = 1440 KM. I did this with a higher speed and a maximum
+       around 180 KM/H. However, it probably doesn't mean that I traveled for
+       8 hours at a constant speed of 180 KM/H!
+
+       This is a real example: go with the flow through Germany (fast!) and
+       stop a few times for gas and coffee. Drive slowly through Austria and
+       the Netherlands. Be careful in the mountains and villages. If you would
+       look at the graphs created from the five-minute averages you would get
+       a totally different picture. You would see the same values on the aver-
+       age and maximum graphs (provided I measured every 300 seconds).  You
+       would be able to see when I stopped, when I was in top gear, when I
+       drove over fast highways etc. The granularity of the data is much
+       higher, so you can see more. However, this takes 12 samples per hour,
+       or 288 values per day, so it would be a lot of data over a longer
+       period of time. Therefore we average it, eventually to one value per
+       day. From this one value, we cannot see much detail, of course.
+
+       Make sure you understand the last few paragraphs. There is no value in
+       only a line and a few axis, you need to know what they mean and inter-
+       pret the data in ana appropriate way. This is true for all data.
+
+       The biggest mistake you can make is to use the collected data for some-
+       thing that it is not suitable for. You would be better off if you
+       didn't have the graph at all.

+
+       You know how to create a database and can put data in it. You can get
+       the numbers out again by creating an image, do math on the data from
+       the database and view the resulte instead of the raw data.  You know
+       about the difference between averages and maxima, and when to use which
+       (or at least you should have an idea).
+
+       RRDtool can do more than what we have learned up to now. Before you
+       continue with the rest of this doc, I recommend that you reread from
+       the start and try some modifications on the examples. Make sure you
+       fully understand everything. It will be worth the effort and helps you
+       not only with the rest of this tutorial, but also in your day to day
+       monitoring long after you read this introduction.

+
+       All right, you feel like continuing. Welcome back and get ready for an
+       increased speed in the examples and explanations.
+
+       You know that in order to view a counter over time, you have to take
+       two numbers and divide the difference of them between the time lapsed.
+       This makes sense for the examples I gave you but there are other possi-
+       bilities.  For instance, I'm able to retrieve the temperature from my
+       router in three places namely the inlet, the so called hot-spot and the
+       exhaust.  These values are not counters.  If I take the difference of
+       the two samples and divide that by 300 seconds I would be asking for
+       the temperature change per second.  Hopefully this is zero! If not, the
+       computer room is probably on fire :)
+
+       So, what can we do?  We can tell RRDtool to store the values we measure
+       directly as they are (this is not entirely true but close enough). The
+       graphs we make will look much better, they will show a rather constant
+       value. I know when the router is busy (it works -> it uses more elec-
+       tricity -> it generates more heat -> the temperature rises). I know
+       when the doors are left open (the room is air conditioned) -> the warm
+       air from the rest of the building flows into the computer room -> the
+       inlet temperature rises). Etc. The data type we use when creating the
+       database before was counter, we now have a different data type and thus
+       a different name for it. It is called GAUGE. There are more such data
+       types:
+
+        - COUNTER   we already know this one
+        - GAUGE     we just learned this one
+        - DERIVE
+        - ABSOLUTE
+
+       The two additional types are DERIVE and ABSOLUTE. Absolute can be used
+       like counter with one difference: RRDtool assumes the counter is reset
+       when it's read. That is: its delta is known without calculation by RRD-
+       tool whereas RRDtool needs to calculate it for the counter type.  Exam-
+       ple: our first example (12'345, 12'357, 12'363, 12'363) would read:
+       unknown, 12, 6, 0. The rest of the calculations stay the same.  The
+       other one, derive, is like counter. Unlike counter, it can also
+       decrease so it can have a negative delta. Again, the rest of the calcu-
+       lations stay the same.
+
+       Let's try them all:
+
+          rrdtool create all.rrd --start 978300900 \

+
+
+       · Line A is a COUNTER type, so it should continuously increment and
+         RRDtool must calculate the differences. Also, RRDtool needs to divide
+         the difference by the amount of time lapsed. This should end up as a
+         straight line at 1 (the deltas are 300, the time is 300).
+
+       · Line B is of type GAUGE. These are "real" values so they should match
+         what we put in: a sort of a wave.
+
+       · Line C is of type DERIVE. It should be a counter that can decrease.
+         It does so between 2'400 and 0, with 1'800 in-between.
+
+       · Line D is of type ABSOLUTE. This is like counter but it works on val-
+         ues without calculating the difference. The numbers are the same and
+         as you can see (hopefully) this has a different result.
+
+       This translates in the following values, starting at 23:10 and ending
+       at 00:10 the next day (where "u" means unknown/unplotted):
+
+        - Line A:  u  u  1  1  1  1  1  1  1  1  1  u
+        - Line B:  u  1  3  5  3  1  2  4  6  4  2  u
+        - Line C:  u  u  2  2  2  0 -2 -6  2  0  2  u
+        - Line D:  u  1  2  3  4  5  6  7  8  9 10  u
+
+       If your PNG shows all this, you know you have entered the data cor-
+       rectly, the RRDtool executable is working properly, your viewer doesn't
+       fool you, and you successfully entered the year 2000 :)
+
+       You could try the same example four times, each time with only one of
+       the lines.
+
+       Let's go over the data again:
+
+       · Line A: 300,600,900 and so on. The counter delta is a constant 300
+         and so is the time delta. A number divided by itself is always 1
+         (except when dividing by zero which is undefined/illegal).
+
+         Why is it that the first point is unknown? We do know what we put
+         into the database, right? True, But we didn't have a value to calcu-
+         late the delta from, so we don't know where we started. It would be
+         wrong to assume we started at zero so we don't!
+
+       · Line B: There is nothing to calculate. The numbers are as they are.
+
+       · Line C: Again, the start-out value is unknown. The same story is
+         holds as for line A. In this case the deltas are not constant, there-
+         fore the line is not either. If we would put the same numbers in the
+         database as we did for line A, we would have gotten the same line.
+         Unlike type counter, this type can decrease and I hope to show you
+         later on why this makes a difference.
+
+       · Line D: Here the device calculates the deltas. Therefore we DO know
+         the first delta and it is plotted. We had the same input as with line
+         A, but the meaning of this input is different and thus the line is
+         different.  In this case the deltas increase each time with 300. The
+         time delta stays at a constant 300 and therefore the division of the
+         two gives increasing values.

+
+       There are a few more basics to show. Some important options are still
+       to be covered and we haven't look at counter wraps yet. First the
+       counter wrap: In our car we notice that the counter shows 999'987. We
+       travel 20 KM and the counter should go to 1'000'007. Unfortunately,
+       there are only six digits on our counter so it really shows 000'007. If
+       we would plot that on a type DERIVE, it would mean that the counter was
+       set back 999'980 KM. It wasn't, and there has to be some protection for
+       this. This protection is only available for type COUNTER which should
+       be used for this kind of counter anyways. How does it work? Type
+       counter should never decrease and therefore RRDtool must assume it
+       wrapped if it does decrease!  If the delta is negative, this can be
+       compensated for by adding the maximum value of the counter + 1. For our
+       car this would be:
+
+        Delta = 7 - 999'987 = -999'980    (instead of 1'000'007-999'987=20)
+
+        Real delta = -999'980 + 999'999 + 1 = 20
+
+       At the time of writing this document, RRDtool knows of counters that
+       are either 32 bits or 64 bits of size. These counters can handle the
+       following different values:
+
+        - 32 bits: 0 ..           4'294'967'295
+        - 64 bits: 0 .. 18'446'744'073'709'551'615
+
+       If these numbers look strange to you, you can view them in their hex-
+       adecimal form:
+
+        - 32 bits: 0 ..         FFFFFFFF
+        - 64 bits: 0 .. FFFFFFFFFFFFFFFF
+
+       RRDtool handles both counters the same. If an overflow occurs and the
+       delta would be negative, RRDtool first adds the maximum of a small
+       counter + 1 to the delta. If the delta is still negative, it had to be
+       the large counter that wrapped. Add the maximum possible value of the
+       large counter + 1 and subtract the erroneously added small value.
+
+       There is a risk in this: suppose the large counter wrapped while adding
+       a huge delta, it could happen, theoretically, that adding the smaller
+       value would make the delta positive. In this unlikely case the results
+       would not be correct. The increase should be nearly as high as the max-
+       imum counter value for that to happen, so chances are you would have
+       several other problems as well and this particular problem would not
+       even be worth thinking about. Even though, I did include an example, so
+       you can judge for yourself.
+
+       The next section gives you some numerical examples for counter-wraps.
+       Try to do the calculations yourself or just believe me if your calcula-
+       tor can't handle the numbers :)

+
+       As you can see from the last two examples, you need strange numbers for
+       RRDtool to fail (provided it's bug free of course), so this should not
+       happen. However, SNMP or whatever method you choose to collect the
+       data, might also report wrong numbers occasionally.  We can't prevent
+       all errors, but there are some things we can do. The RRDtool "create"
+       command takes two special parameters for this. They define the minimum
+       and maximum allowed values. Until now, we used "U", meaning "unknown".
+       If you provide values for one or both of them and if RRDtool receives
+       data points that are outside these limits, it will ignore those values.
+       For a thermometer in degrees Celsius, the absolute minimum is just
+       under -273. For my router, I can assume this minimum is much higher so
+       I would set it to 10, where as the maximum temperature I would set to
+       80. Any higher and the device would be out of order.
+
+       For the speed of my car, I would never expect negative numbers and also
+       I would not expect a speed  higher than 230. Anything else, and there
+       must have been an error. Remember: the opposite is not true, if the
+       numbers pass this check, it doesn't mean that they are correct. Always
+       judge the graph with a healthy dose of suspicion if it seems weird to
+       you.

+
+       One important feature of RRDtool has not been explained yet: it is vir-
+       tually impossible to collect data and feed it into RRDtool on exact
+       intervals. RRDtool therefore interpolates the data, so they are stored
+       on exact intervals. If you do not know what this means or how it works,
+       then here's the help you seek:
+
+       Suppose a counter increases by exactly one for every second. You want
+       to measure it in 300 seconds intervals. You should retrieve values that
+       are exactly 300 apart. However, due to various circumstances you are a
+       few seconds late and the interval is 303. The delta will also be 303 in
+       that case. Obviously, RRDtool should not put 303 in the database and
+       make you believe that the counter increased by 303 in 300 seconds.
+       This is where RRDtool interpolates: it alters the 303 value as if it
+       would have been stored earlier and it will be 300 in 300 seconds.  Next
+       time you are at exactly the right time. This means that the current
+       interval is 297 seconds and also the counter increased by 297. Again,
+       RRDtool interpolates and stores 300 as it should be.
+
+             in the RRD                 in reality
+
+        time+000:   0 delta="U"   time+000:    0 delta="U"
+        time+300: 300 delta=300   time+300:  300 delta=300
+        time+600: 600 delta=300   time+603:  603 delta=303
+        time+900: 900 delta=300   time+900:  900 delta=297
+
+       Let's create two identical databases. I've chosen the time range
+       920'805'000 to 920'805'900 as this goes very well with the example num-
+       bers.

+             --start 920804700          \
+             DS:seconds:COUNTER:600:U:U \
+             RRA:AVERAGE:0.5:1:24

+       It's time now to wrap up this tutorial. We covered all the basics for
+       you to be able to work with RRDtool and to read the additional
+       documentation available. There is plenty more to discover about RRDtool
+       and you will find more and more uses for this package. You can easly
+       create graphs using just the examples provided and using only RRDtool.
+       You can also use one of the front ends to RRDtool that are available.

+       users. A lot of the stuff that I know about MRTG (and therefore about
+       RRDtool) I've learned while just reading the list without posting to
+       it. I did not need to ask the basic questions as they are answered in
+       the FAQ (read it!) and in various mails by other users. With thousands
+       of users all over the world, there will always be people who ask ques-
+       tions that you can answer because you read this and other documentation
+       and they didn't.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBupdate\fR function feeds new data values into an \fB\s-1RRD\s0\fR. The data
+is time aligned (interpolated) according to the properties of the
+\&\fB\s-1RRD\s0\fR to which the data is written.
+.IP "\fBupdatev\fR" 8
+.IX Item "updatev"
+This alternate version of \fBupdate\fR takes the same arguments and
+performs the same function. The \fIv\fR stands for \fIverbose\fR, which
+describes the output returned. \fBupdatev\fR returns a list of any and all
+consolidated data points (CDPs) written to disk as a result of the
+invocation of update. The values are indexed by timestamp (time_t),
+\&\s-1RRA\s0 (consolidation function and PDPs per \s-1CDP\s0), and data source (name).
+Note that depending on the arguments of the current and previous call to
+update, the list may have no entries or a large number of entries.
+.IP "\fIfilename\fR" 8
+.IX Item "filename"
+The name of the \fB\s-1RRD\s0\fR you want to update.
+.IP "\fB\-\-template\fR|\fB\-t\fR \fIds-name\fR[\fB:\fR\fIds-name\fR]..." 8
+.IX Item "--template|-t ds-name[:ds-name]..."
+By default, the \fBupdate\fR function expects its data input in the order
+the data sources are defined in the \s-1RRD\s0, excluding any \s-1COMPUTE\s0 data
+sources (i.e. if the third data source \fB\s-1DST\s0\fR is \s-1COMPUTE\s0, the third
+input value will be mapped to the fourth data source in the \fB\s-1RRD\s0\fR and
+so on). This is not very error resistant, as you might be sending the
+wrong data into an \s-1RRD\s0.
+.Sp
+The template switch allows you to specify which data sources you are
+going to update and in which order. If the data sources specified in
+the template are not available in the \s-1RRD\s0 file, the update process
+will abort with an error message.
+.Sp
+While it appears possible with the template switch to update data sources
+asynchronously, \fBRRDtool\fR implicitly assigns non-COMPUTE data sources missing
+from the template the \fI*UNKNOWN*\fR value.
+.Sp
+Do not specify a value for a \s-1COMPUTE\s0 \fB\s-1DST\s0\fR in the \fBupdate\fR
+function. If this is done accidentally (and this can only be done
+using the template switch), \fBRRDtool\fR will ignore the value specified
+for the \s-1COMPUTE\s0 \fB\s-1DST\s0\fR.
+.IP "\fBN\fR|\fItimestamp\fR\fB:\fR\fIvalue\fR[\fB:\fR\fIvalue\fR...]" 8
+.IX Item "N|timestamp:value[:value...]"
+The data used for updating the \s-1RRD\s0 was acquired at a certain
+time. This time can either be defined in seconds since 1970\-01\-01 or
+by using the letter 'N', in which case the update time is set to be
+the current time. Negative time values are subtracted from the current
+time. An \s-1AT_STYLE\s0 \s-1TIME\s0 \s-1SPECIFICATION\s0 (see the \fIrrdfetch\fR
+documentation) may also be used by delimiting the end of the time
+specification with the '@' character instead of a ':'. Getting the
+timing right to the second is especially important when you are
+working with data-sources of type \fB\s-1COUNTER\s0\fR, \fB\s-1DERIVE\s0\fR or
+\&\fB\s-1ABSOLUTE\s0\fR.
+.Sp
+The remaining elements of the argument are \s-1DS\s0 updates. The order of
+this list is the same as the order the data sources were defined in
+the \s-1RRA\s0. If there is no data for a certain data\-source, the letter
+\&\fBU\fR (e.g., N:0.1:U:1) can be specified.
+.Sp
+The format of the value acquired from the data source is dependent on

+
+=head1 DESCRIPTION
+
+The B<update> function feeds new data values into an B<RRD>. The data
+is time aligned (interpolated) according to the properties of the
+B<RRD> to which the data is written.
+
+=over 8
+
+=item B<updatev>
+
+This alternate version of B<update> takes the same arguments and
+performs the same function. The I<v> stands for I<verbose>, which
+describes the output returned. B<updatev> returns a list of any and all
+consolidated data points (CDPs) written to disk as a result of the
+invocation of update. The values are indexed by timestamp (time_t),
+RRA (consolidation function and PDPs per CDP), and data source (name).
+Note that depending on the arguments of the current and previous call to
+update, the list may have no entries or a large number of entries.
+
+=item I<filename>
+
+The name of the B<RRD> you want to update.
+
+=item B<--template>|B<-t> I<ds-name>[B<:>I<ds-name>]...
+
+By default, the B<update> function expects its data input in the order
+the data sources are defined in the RRD, excluding any COMPUTE data
+sources (i.e. if the third data source B<DST> is COMPUTE, the third
+input value will be mapped to the fourth data source in the B<RRD> and
+so on). This is not very error resistant, as you might be sending the
+wrong data into an RRD.
+
+The template switch allows you to specify which data sources you are
+going to update and in which order. If the data sources specified in
+the template are not available in the RRD file, the update process
+will abort with an error message.
+
+While it appears possible with the template switch to update data sources
+asynchronously, B<RRDtool> implicitly assigns non-COMPUTE data sources missing
+from the template the I<*UNKNOWN*> value.
+
+Do not specify a value for a COMPUTE B<DST> in the B<update>
+function. If this is done accidentally (and this can only be done
+using the template switch), B<RRDtool> will ignore the value specified
+for the COMPUTE B<DST>.
+
+=item B<N>|I<timestamp>B<:>I<value>[B<:>I<value>...]
+
+The data used for updating the RRD was acquired at a certain
+time. This time can either be defined in seconds since 1970-01-01 or
+by using the letter 'N', in which case the update time is set to be
+the current time. Negative time values are subtracted from the current
+time. An AT_STYLE TIME SPECIFICATION (see the I<rrdfetch>
+documentation) may also be used by delimiting the end of the time
+specification with the '@' character instead of a ':'. Getting the
+timing right to the second is especially important when you are
+working with data-sources of type B<COUNTER>, B<DERIVE> or
+B<ABSOLUTE>.
+
+The remaining elements of the argument are DS updates. The order of
+this list is the same as the order the data sources were defined in
+the RRA. If there is no data for a certain data-source, the letter
+B<U> (e.g., N:0.1:U:1) can be specified.
+
+The format of the value acquired from the data source is dependent on
+the data source type chosen. Normally it will be numeric, but the data
+acquisition modules may impose their very own parsing of this
+parameter as long as the colon (B<:>) remains the data source value
+separator.

+               By default, the u\bup\bpd\bda\bat\bte\be function expects its data input in the

+               COMPUTE data sources (i.e. if the third data source D\bDS\bST\bT is COM-
+               PUTE, the third input value will be mapped to the fourth data
+               source in the R\bRR\bRD\bD and so on). This is not very error resistant,
+               as you might be sending the wrong data into an RRD.
+
+               The template switch allows you to specify which data sources

+               specified in the template are not available in the RRD file,

+
+               While it appears possible with the template switch to update

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBxport\fR function's main purpose is to write an \s-1XML\s0 formatted
+representation of the data stored in one or several \fB\s-1RRD\s0\fRs. It
+can also extract numerical reports.
+.PP
+If no \fI\s-1XPORT\s0\fR statements are found, there will be no output.
+.IP "\fB\-s\fR|\fB\-\-start\fR \fIseconds\fR (default end\-1day)" 4
+.IX Item "-s|--start seconds (default end-1day)"
+The time when the exported range should begin. Time in seconds since
+epoch (1970\-01\-01) is required. Negative numbers are relative to the
+current time. By default one day worth of data will be printed.
+See also AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0 section in the \fIrrdfetch\fR
+documentation for a detailed explanation on how to specify time.
+.IP "\fB\-e\fR|\fB\-\-end\fR \fIseconds\fR (default now)" 4
+.IX Item "-e|--end seconds (default now)"
+The time when the exported range should end. Time in seconds since epoch.
+See also AT-STYLE \s-1TIME\s0 \s-1SPECIFICATION\s0 section in the \fIrrdfetch\fR
+documentation for a detailed explanation of ways to specify time.
+.IP "\fB\-m\fR|\fB\-\-maxrows\fR \fIrows\fR (default 400 rows)" 4
+.IX Item "-m|--maxrows rows (default 400 rows)"
+This works like the \fB\-w\fR|\fB\-\-width\fR parameter of \fIrrdgraph\fR.

+=head1 NAME
+
+rrdxport - Export data in XML format based on data from one or several RRD
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<xport>
+S<[B<-s>|B<--start> I<seconds>]>
+S<[B<-e>|B<--end> I<seconds>]>
+S<[B<-m>|B<--maxrows> I<rows>]>
+S<[B<--step> I<value>]>
+S<[B<DEF:>I<vname>B<=>I<rrd>B<:>I<ds-name>B<:>I<CF>]>
+S<[B<CDEF:>I<vname>B<=>I<rpn-expression>]>
+S<[B<XPORT>B<:>I<vname>[B<:>I<legend>]]>
+
+=head1 DESCRIPTION
+
+The B<xport> function's main purpose is to write an XML formatted
+representation of the data stored in one or several B<RRD>s. It
+can also extract numerical reports.
+
+If no I<XPORT> statements are found, there will be no output.
+
+=over
+
+=item B<-s>|B<--start> I<seconds> (default end-1day)
+
+The time when the exported range should begin. Time in seconds since
+epoch (1970-01-01) is required. Negative numbers are relative to the
+current time. By default one day worth of data will be printed.
+See also AT-STYLE TIME SPECIFICATION section in the I<rrdfetch>
+documentation for a detailed explanation on how to specify time.
+
+=item B<-e>|B<--end> I<seconds> (default now)
+
+The time when the exported range should end. Time in seconds since epoch.
+See also AT-STYLE TIME SPECIFICATION section in the I<rrdfetch>
+documentation for a detailed explanation of ways to specify time.
+
+=item B<-m>|B<--maxrows> I<rows> (default 400 rows)
+
+This works like the B<-w>|B<--width> parameter of I<rrdgraph>.
+In fact it is exactly the same, but the parameter was renamed to
+describe its purpose in this module. See I<rrdgraph> documentation
+for details.
+
+=item B<--step> I<value> (default automatic)
+
+See L<rrdgraph> documentation.
+
+=item B<--enumds> 
+
+The generated xml should contain the data values in enumerated tags.
+
+ <v0>val</v0><v1>val</v1>
+
+=item B<DEF:>I<vname>B<=>I<rrd>B<:>I<ds-name>B<:>I<CF>
+
+See I<rrdgraph> documentation.
+
+=item B<CDEF:>I<vname>B<=>I<rpn-expression>
+
+See I<rrdgraph> documentation.
+
+=item B<XPORT:>I<vname>B<:>B<:>I<legend>
+
+At least one I<XPORT> statement should be present. The values
+referenced by I<vname> are printed. Optionally add a legend.
+
+=back
+
+=head1 Output format
+
+The output is enclosed in an B<xport> element and contains two
+blocks. The first block is enclosed by a B<meta> element and
+contains some meta data. The second block is enclosed by a
+B<data> element and contains the data rows.
+
+Let's assume that the I<xport> command looks like this:
+
+  rrdtool xport \
+          --start now-1h --end now \
+          DEF:xx=host-inout.lo.rrd:output:AVERAGE \
+         DEF:yy=host-inout.lo.rrd:input:AVERAGE \
+          CDEF:aa=xx,yy,+,8,* \
+          XPORT:xx:"out bytes" \
+          XPORT:aa:"in and out bits"
+
+The resulting meta data section is (the values will depend on the
+RRD characteristics):
+
+  <meta>
+    <start>1020611700</start>
+    <step>300</step>
+    <end>1020615600</end>
+    <rows>14</rows>
+    <columns>2</columns>
+    <legend>
+      <entry>out bytes</entry>
+      <entry>in and out bits</entry>
+    </legend>
+  </meta>
+
+The resulting data section is:
+
+  <data>
+    <row><t>1020611700</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row>

+RRDtool Performance Tester
+--------------------------
+Runnion on $RRDs::VERSION;
+
+RRDtool update performance is ultimately disk-bound. Since very little data
+does actually get written to disk in a single update, the performance
+is highly dependent on the cache situation in your machine.
+
+This test tries to cater for this. It works like this:
+
+1) Create 100 RRD files (and sync them to disk)
+
+2) Update the 100 RRD file three times in a row.
+   We run the Update several times to see the difference
+   it makes in the cache.
+
+3) Go back to 1)
+
+NOTE

+%description
+RRD is the Acronym for Round Robin Database. RRD is a system to store and
+display time-series data (i.e. network bandwidth, machine-room temperature,
+server load average). It stores the data in a very compact way that will not
+expand over time, and it presents useful graphs by processing the data to
+enforce a certain data density. It can be used either via simple wrapper
+scripts (from shell or Perl) or via frontends that poll network devices and
+put a friendly user interface on it.

+# This flag accepts an argument of the form current[:revision[:age]]. So,
+# passing -version-info 3:12:1 sets current to 3, revision to 12, and age to 1.
+#
+# If either revision or age are omitted, they default to 0. Also note that
+# age must be less than or equal to the current interface number.
+#
+# Here are a set of rules to help you update your library version information:
+#
+#   1. Start with version information of 0:0:0 for each libtool library.
+#
+#   2. Update the version information only immediately before a public
+#   release of your software. More frequent updates are unnecessary, and
+#   only guarantee that the current interface number gets larger faster.
+#
+#   3. If the library source code has changed at all since the last update,
+#   then increment revision (c:r:a becomes c:r+1:a).
+#
+#   4. If any interfaces have been added, removed, or changed since the last
+#   update, increment current, and set revision to 0.
+#
+#   5. If any interfaces have been added since the last public release, then
+#   increment age.
+#
+#   6. If any interfaces have been removed since the last public release,
+#   then set age to 0.
+#
+# Never try to set the interface numbers so that they correspond to the
+# release number of your package. This is an abuse that only fosters
+# misunderstanding of the purpose of library versions. Instead, use the
+# -release flag (see Release numbers), but be warned that every release of
+# your package will not be binary compatible with any other release.

+# This flag accepts an argument of the form current[:revision[:age]]. So,
+# passing -version-info 3:12:1 sets current to 3, revision to 12, and age to 1.
+#
+# If either revision or age are omitted, they default to 0. Also note that
+# age must be less than or equal to the current interface number.
+#
+# Here are a set of rules to help you update your library version information:
+#
+#   1. Start with version information of 0:0:0 for each libtool library.
+#
+#   2. Update the version information only immediately before a public
+#   release of your software. More frequent updates are unnecessary, and
+#   only guarantee that the current interface number gets larger faster.
+#
+#   3. If the library source code has changed at all since the last update,
+#   then increment revision (c:r:a becomes c:r+1:a).
+#
+#   4. If any interfaces have been added, removed, or changed since the last
+#   update, increment current, and set revision to 0.
+#
+#   5. If any interfaces have been added since the last public release, then
+#   increment age.
+#
+#   6. If any interfaces have been removed since the last public release,
+#   then set age to 0.
+#
+# Never try to set the interface numbers so that they correspond to the
+# release number of your package. This is an abuse that only fosters
+# misunderstanding of the purpose of library versions. Instead, use the
+# -release flag (see Release numbers), but be warned that every release of
+# your package will not be binary compatible with any other release.

+ * 1 winding number have the color @rgba composited over them (ie,

+ ***
+ *
+ * Fowler/Noll/Vo- hash
+ *
+ * The basis of this hash algorithm was taken from an idea sent
+ * as reviewer comments to the IEEE POSIX P1003.2 committee by:
+ *
+ *      Phong Vo (http://www.research.att.com/info/kpv/)
+ *      Glenn Fowler (http://www.research.att.com/~gsf/)
+ *
+ * In a subsequent ballot round:
+ *
+ *      Landon Curt Noll (http://reality.sgi.com/chongo/)
+ *
+ * improved on their algorithm.  Some people tried this hash
+ * and found that it worked rather well.  In an EMail message
+ * to Landon, they named it the ``Fowler/Noll/Vo'' or FNV hash.
+ *
+ * FNV hashes are architected to be fast while maintaining a low
+ * collision rate. The FNV speed allows one to quickly hash lots
+ * of data while maintaining a reasonable collision rate.  See:
+ *
+ *      http://reality.sgi.com/chongo/tech/comp/fnv/
+ *
+ * for more details as well as other forms of the FNV hash.
+ *
+ ***
+ *
+ * NOTE: The FNV-0 historic hash is not recommended.  One should use
+ *      the FNV-1 hash instead.
+ *
+ * To use the 32 bit FNV-0 historic hash, pass FNV0_32_INIT as the
+ * Fnv32_t hashval argument to fnv_32_buf() or fnv_32_str().
+ *
+ * To use the 64 bit FNV-0 historic hash, pass FNV0_64_INIT as the
+ * Fnv64_t hashval argument to fnv_64_buf() or fnv_64_str().
+ *
+ * To use the recommended 32 bit FNV-1 hash, pass FNV1_32_INIT as the
+ * Fnv32_t hashval argument to fnv_32_buf() or fnv_32_str().
+ *
+ * To use the recommended 64 bit FNV-1 hash, pass FNV1_64_INIT as the

+ * hash_32 - 32 bit Fowler/Noll/Vo hash code
+ *
+ *
+ ***
+ *
+ * Fowler/Noll/Vo hash
+ *
+ * The basis of this hash algorithm was taken from an idea sent
+ * as reviewer comments to the IEEE POSIX P1003.2 committee by:
+ *
+ *      Phong Vo (http://www.research.att.com/info/kpv/)
+ *      Glenn Fowler (http://www.research.att.com/~gsf/)
+ *
+ * In a subsequent ballot round:
+ *
+ *      Landon Curt Noll (http://reality.sgi.com/chongo/)
+ *
+ * improved on their algorithm.  Some people tried this hash
+ * and found that it worked rather well.  In an EMail message
+ * to Landon, they named it the ``Fowler/Noll/Vo'' or FNV hash.
+ *
+ * FNV hashes are architected to be fast while maintaining a low
+ * collision rate. The FNV speed allows one to quickly hash lots
+ * of data while maintaining a reasonable collision rate.  See:
+ *
+ *      http://reality.sgi.com/chongo/tech/comp/fnv/
+ *
+ * for more details as well as other forms of the FNV hash.
+ ***
+ *
+ * NOTE: The FNV-0 historic hash is not recommended.  One should use
+ *      the FNV-1 hash instead.
+ *
+ * To use the 32 bit FNV-0 historic hash, pass FNV0_32_INIT as the
+ * Fnv32_t hashval argument to fnv_32_buf() or fnv_32_str().
+ *
+ * To use the recommended 32 bit FNV-1 hash, pass FNV1_32_INIT as the
+ * Fnv32_t hashval argument to fnv_32_buf() or fnv_32_str().

+ *    -3h20m or +5s2m 'm' means 'minutes')
+ *
+ * 2. Out of context (i.e. right after the '+' or '-' sign) the
+ *    meaning of 'm' is guessed from the number it directly follows.
+ *    Currently, if the number absolute value is below 25 it is assumed
+ *    that 'm' means months, otherwise it is treated as minutes.
+ *    (e.g., -25m == -25 minutes, while +24m == +24 months)

+ * allow to pass an open filehandle into rrd_graph as an extra argument
+ *
+ * Revision 1.6  2003/11/11 19:46:21  oetiker
+ * replaced time_value with rrd_time_value as MacOS X introduced a struct of that name in their standard headers
+ *
+ * Revision 1.5  2003/04/25 18:35:08  jake
+ * Alternate update interface, updatev. Returns info about CDPs written to disk as result of update. Output format is similar to rrd_info, a hash of key-values.
+ *
+ * Revision 1.4  2003/04/01 22:52:23  jake
+ * Fix Win32 build. VC++ 6.0 and 7.0 now use the thread-safe code.
+ *
+ * Revision 1.3  2003/02/13 07:05:27  oetiker
+ * Find attached the patch I promised to send to you. Please note that there
+ * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
+ * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
+ * library is identical to librrd, but it contains support code for per-thread
+ * global variables currently used for error information only. This is similar
+ * to how errno per-thread variables are implemented.  librrd_th must be linked
+ * alongside of libpthred
+ *
+ * There is also a new file "THREADS", holding some documentation.

+Description of data structures:
+
+  Ideally, the struct should be a list of fonts, and each font
+  is a list of character-info.
+  Each character has a structure:

+      int width;
+      struct {
+       char16 nextchar;
+       int deltawidth;
+      } kernings[];
+      struct {
+       char16 nextchar;
+       char16 resultingchar;
+      } ligatures[];
+    }
+
+    The data for typical fonts makes this a very sparse data structure.
+    For most fonts, only the letter "f" has ligatures.
+    All fonts have all (or almost all) of the characters 32-126,
+    most fonts have all 161-255,
+    and all fonts have very few 256-65535.
+    Most kerning pairs have both chars 32-126.
+
+    The most basic design decisionÊis to have all this data as 
+    const C globals all set up by array/struct initialisers
+    so runtime setup overhead is minimal.
+    The complete other possibility would be to parse and load
+    this info at runtime, but for rrdtool I have preferred
+    speed for flexibility as the same few fonts will be used 
+    zillions of times.
+
+    So the idea is to rewrite the above structure into
+    something which:
+    1) uses/wastes minimal memory
+    2) is fast for most characters
+    3) supports at least Iso-Latin-1, prefer full unicode.
+    4) doesn't need full precision in char width
+       (we can afford to loose 0.2% as rrdtool only needs to calculate
+       overall layout of elements, not positioning individual
+       characters)
+    5) can be written as constant initialisers to C structs/arrays
+       so we don't have runtime overhead starting rrdtool.
+    6) can be easily generated by some script so it is easy
+       to select a set of fonts and have the C data updated.
+       So adding/removing fonts is a matter of a recompile.
+
+Implementation design:
+    All character structs are sorted by unicode value. Info for
+    characters below 32 is discarded and the chars are treated 
+    as a space. Missing characters in the 32-126 range are 
+    substituted with default values so we can use direct array 
+    access for those. For characters above 126, binary search 
+    is used (not yet, liniar now but uses good guess for most latin 1
+    characters).
+
+    Ligature handling can be discarded as ligatures have very small
+    effects on string width. The width of the "fi" ligature
+    is the same (or very close) to the width of "f" plus the width 
+    of "i".
+    If implemented, it can be a simple list (global for the font,
+    not for each character) because all fonts I've seen that have
+    ligatures has max 3 pairs: "fi", "fl", "ffl" and no other. 
+
+    Most characters has less than 10 kern pairs, few 10-20, and
+    extremly few 20-30. This is implemented as a simple
+    linear search with characters 256-65536 encoding using a prefix
+    so most kern pairs only take 2 bytes:
+    unsigned 8 bit char value and signed 8 bit kern width.
+    Using a non-packed format would enable binary search, but
+    would use almost twice as much memory for a yet unknown
+    gain in speed.
+
+    Character widths are stored as unsigned bytes. Width of
+    one character is font-size * bytevalue * (1000 / 6)
+    AFM specifies widths as integers with 1000 representing 1 * font-size.
+    Kerning delta widths has same scaling factor, but the value
+    is a signed byte as many kerning widths are negative and smaller
+    than avarage character width.
+
+    Kerning info is stored in a shared packed int8 array
+    to reduce the number of structs and memory usage.
+    This sets the maximum number of kerning pairs to
+    approx 15000.
+      The font I have seen with most kern pairs is
+      "Bodoni Old Face BE Bold Italic Oldstyle Figures"
+      which has 1718 pairs for 62 chars.
+      Typical fonts have 100-150 pairs.
+    For each character needs then only a 16 bit index
+    into this shared table.
+    The format of the sub-arrays are:
+      count ( unicode deltawidth )
+    with the (...) repeated count times.
+    The count and the unicode is packed because a lot
+    entries is less than 256, and most below 400.
+    Therefore an escape sequence is used.
+    If the value is >= 510
+      1, high-8bits, low-8bits
+    else if the value is >= 254
+      0, value minus 254
+    else
+      value plus 1
+    An index of zero is treated as a NULL pointer,
+    and the first byte in a shared array is
+    therefore not used (and filled with a dummy value).
+    The array is only created if non-empty.
+       No entries can be zero (they are redundant),
+       and no subarray can be empty (as the index pointer
+       then is 0 meaning no sub array).
+       The deltawidth is stored as a non-escaped signed byte.
+
+    So for each character needed info is:
+      width: unsigned 8 bit int.
+      kerning-subarray-index: unsigned 16 bit int.
+
+    The first 126-32+1 entries are for the characters
+    32-126. If any is missing, a dummy entry is created.
+    For characters 126-65535 a font-global
+    array of struct {unicode, char-index} is
+    used for binary search (not yet, liniar now).
+
+    Ligatures can be implemented as a font-global
+    array of struct {
+      unicode char1, char2, resultingchar;
+    }
+
+    Font-global info is stored in a struct afm_fontinfo (see below).
+
+    The highchars_index and ligatures structures are flattened
+    to a simple array to avoid accidental padding between
+    structs if the structsize is problematic for some platforms.
+
+    All fonts are stored in an array of this struct,
+    sorted by fullname for binary search (not yet sorted).
+
+    The .afm files are compiled by a perl script which creates
+    rrd_afm_data.c 
+    The only thing rrd_afm_data.c contains is this compiled data.
+
+    Compiled on Mac OS X the size of rrd_afm_data.o
+    is 67 Kb for the standard 14 postscript fonts,
+    and 490 Kb for a set of 276 Adobe fonts.

+ * a patch to avoid a memory leak and a Makefile.am patch to
+ * distribute all required source files -- Peter Stamfest <peter@stamfest.at>
+ *
+ * Revision 1.3  2003/02/13 07:05:27  oetiker
+ * Find attached the patch I promised to send to you. Please note that there
+ * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
+ * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
+ * library is identical to librrd, but it contains support code for per-thread
+ * global variables currently used for error information only. This is similar
+ * to how errno per-thread variables are implemented.  librrd_th must be linked

+ * Revision 1.3  2001/12/24 06:51:49  alex
+ * A patch of size 44Kbytes... in short:
+ *
+ * Found and repaired the off-by-one error in rrd_fetch_fn().
+ * As a result I had to remove the hacks in rrd_fetch_fn(),
+ * rrd_tool.c, vdef_calc(), data_calc(), data_proc() and
+ * reduce_data().  There may be other places which I didn't
+ * find so be careful.
+ *
+ * Enhanced debugging in rrd_fetch_fn(), it shows the RRA selection
+ * process.
+ *
+ * Added the ability to print VDEF timestamps.  At the moment it
+ * is a hack, I needed it now to fix the off-by-one error.
+ * If the format string is "%c" (and nothing else!), the time
+ * will be printed by both ctime() and as a long int.
+ *
+ * Moved some code around (slightly altering it) from rrd_graph()
+ *   initializing     now in rrd_graph_init()
+ *   options parsing  now in rrd_graph_options()
+ *   script parsing   now in rrd_graph_script()

+ * The RRD Database Structure
+ * ---------------------------
+ * 
+ * In oder to properly describe the database structure lets define a few
+ * new words:
+ *
+ * ds - Data Source (ds) providing input to the database. A Data Source (ds)
+ *       can be a traffic counter, a temperature, the number of users logged
+ *       into a system. The rrd database format can handle the input of
+ *       several Data Sources (ds) in a singe database.
+ *  
+ * dst - Data Source Type (dst). The Data Source Type (dst) defines the rules
+ *       applied to Build Primary Data Points from the input provided by the
+ *       data sources (ds).
+ *
+ * pdp - Primary Data Point (pdp). After the database has accepted the
+ *       input from the data sources (ds). It starts building Primary
+ *       Data Points (pdp) from the data. Primary Data Points (pdp)
+ *       are evenly spaced along the time axis (pdp_step). The values
+ *       of the Primary Data Points are calculated from the values of
+ *       the data source (ds) and the exact time these values were
+ *       provided by the data source (ds).
+ *
+ * pdp_st - PDP Start (pdp_st). The moments (pdp_st) in time where
+ *       these steps occur are defined by the moments where the
+ *       number of seconds since 1970-jan-1 modulo pdp_step equals
+ *       zero (pdp_st). 
+ *
+ * cf -  Consolidation Function (cf). An arbitrary Consolidation Function (cf)
+ *       (averaging, min, max) is applied to the primary data points (pdp) to
+ *       calculate the consolidated data point.
+ *
+ * cdp - Consolidated Data Point (cdp) is the long term storage format for data
+ *       in the rrd database. Consolidated Data Points represent one or
+ *       several primary data points collected along the time axis. The
+ *       Consolidated Data Points (cdp) are stored in Round Robin Archives
+ *       (rra).
+ *
+ * rra - Round Robin Archive (rra). This is the place where the
+ *       consolidated data points (cdp) get stored. The data is
+ *       organized in rows (row) and columns (col). The Round Robin
+ *       Archive got its name from the method data is stored in
+ *       there. An RRD database can contain several Round Robin
+ *       Archives. Each Round Robin Archive can have a different row
+ *       spacing along the time axis (pdp_cnt) and a different
+ *       consolidation function (cf) used to build its consolidated
+ *       data points (cdp).  
+ * 
+ * rra_st - RRA Start (rra_st). The moments (rra_st) in time where
+ *       Consolidated Data Points (cdp) are added to an rra are
+ *       defined by the moments where the number of seconds since
+ *       1970-jan-1 modulo pdp_cnt*pdp_step equals zero (rra_st).
+ *
+ * row - Row (row). A row represent all consolidated data points (cdp)
+ *       in a round robin archive who are of the same age.
+ *       
+ * col - Column (col). A column (col) represent all consolidated
+ *       data points (cdp) in a round robin archive (rra) who
+ *       originated from the same data source (ds).
+ *

+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+ * each block. realloc is very slow in Mac OS X for huge blocks, e.g. when
+ * restoring databases from huge xml files. This patch finds the size of the
+ * file, and starts out with malloc'ing the full size.
+ * -- Peter Speck <speck@ruc.dk>
+ *
+ * Revision 1.8  2003/04/11 19:43:44  oetiker
+ * New special value COUNT which allows calculations based on the position of a
+ * value within a data set. Bug fix in rrd_rpncalc.c. PREV returned erroneus
+ * value for the second value. Bug fix in rrd_restore.c. Bug causing seek error
+ * when accesing an RRD restored from an xml that holds an RRD version <3.
+ * --  Ruben Justo <ruben@ainek.com>
+ *
+ * Revision 1.7  2003/03/31 21:22:12  oetiker
+ * enables RRDtool updates with microsecond or in case of windows millisecond
+ * precision. This is needed to reduce time measurement error when archive step
+ * is small. (<30s) --  Sasha Mikheev <sasha@avalon-net.co.il>
+ *
+ * Revision 1.6  2003/02/13 07:05:27  oetiker
+ * Find attached the patch I promised to send to you. Please note that there
+ * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
+ * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
+ * library is identical to librrd, but it contains support code for per-thread
+ * global variables currently used for error information only. This is similar
+ * to how errno per-thread variables are implemented.  librrd_th must be linked
+ * alongside of libpthred
+ *
+ * There is also a new file "THREADS", holding some documentation.
+ *
+ * -- Peter Stamfest <peter@stamfest.at>
+ *
+ * Revision 1.5  2002/06/20 00:21:03  jake
+ * More Win32 build changes; thanks to Kerry Calvert.
+ *
+ * Revision 1.4  2002/02/01 20:34:49  oetiker
+ * fixed version number and date/time
+ *
+ * Revision 1.3  2001/03/04 13:01:55  oetiker
+ * Aberrant Behavior Detection support. A brief overview added to rrdtool.pod.
+ * Major updates to rrd_update.c, rrd_create.c. Minor update to other core files.
+ * This is backwards compatible! But new files using the Aberrant stuff are not readable
+ * by old rrdtool versions. See http://cricket.sourceforge.net/aberrant/rrd_hw.htm
+ * -- Jake Brutlag <jakeb@corp.webtv.net>
+ *
+ * Revision 1.2  2001/03/04 10:29:20  oetiker
+ * fixed filedescriptor leak
+ * -- Mike Franusich <mike@franusich.com>

+ * suggest this to preserve algorithm stability. It will not invalidate
+ * RRD files created and smoothed with the old code.
+ * (4) Adds the aberrant-reset flag to rrd tune. This operation, which is
+ * specified for a single data source, causes the holt-winters algorithm to
+ * forget everthing it has learned and start over.
+ * (5) Fixes a few out-of-date code comments.
+ *
+ * Revision 1.3  2001/03/07 21:21:54  oetiker
+ * complete rewrite of rrdgraph documentation. This also includs info
+ * on upcomming/planned changes to the rrdgraph interface and functionality
+ * -- Alex van den Bogaerdt <alex@slot.hollandcasino.nl>
+ *
+ * Revision 1.2  2001/03/04 13:01:55  oetiker
+ * Aberrant Behavior Detection support. A brief overview added to rrdtool.pod.
+ * Major updates to rrd_update.c, rrd_create.c. Minor update to other core files.
+ * This is backwards compatible! But new files using the Aberrant stuff are not readable
+ * by old rrdtool versions. See http://cricket.sourceforge.net/aberrant/rrd_hw.htm

+ *          be at least maxs characters available at the address
