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. + + 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.) + +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. + + 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. + + 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 diff --git a/COPYRIGHT b/COPYRIGHT new file mode 100644 index 0000000..ab5c695 --- /dev/null +++ b/COPYRIGHT @@ -0,0 +1,90 @@ + RRDTOOL - Round Robin Database Tool + A tool for fast logging of numerical data graphical display + of this data. + + Copyright (c) 1998-2006 Tobias Oetiker + All rights reserved. + + GNU GPL License + =============== + + This program is free software; you can redistribute it and/or modify it + under the terms of the GNU General Public License as published by the Free + Software Foundation; either version 2 of the License, or (at your option) + any later version. + + This program 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.

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 /* for off_t */ +# include /* for SEEK_* and off_t */ +# ifdef VMS +# include /* 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 /* for off_t */ +# include /* for SEEK_* and off_t */ +# ifdef VMS +# include /* 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.

B<$RRDp::error_mode>, B<$RRDp::error> + +=head1 DESCRIPTION + +With this module you can safely communicate with the RRDtool. + +After every B you have to issue an B command to get +Bs 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 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 + +Load the RRDp::pipe module. + +=item B I + +start RRDtool. The argument must be the path to the RRDtool executable + +=item B I + +pass commands on to RRDtool. check the RRDtool documentation for +more info on the RRDtool commands. + +=item $answer = B + +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.

See the B 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.

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 is the most complex of +the pack regarding return values. There are 4 values.

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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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.

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.

NAME

+

RRDp - Attach RRDtool from within a perl script via a set of pipes;

+

+

+
+

SYNOPSIS

+

use RRDp

+

RRDp::start path to RRDtool executable

+

RRDp::cmd rrdtool commandline

+

$answer = RRD::read

+

$status = RRD::end

+

$RRDp::user, $RRDp::sys, $RRDp::real, $RRDp::error_mode, $RRDp::error

+

+

+
+

DESCRIPTION

+

With this module you can safely communicate with the RRDtool.

+

After every RRDp::cmd you have to issue an RRDp::read command to get +RRDtools 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, RRDp::read will return an undefined variable.

+

If you import the PERFORMANCE variables into your namespace, +you can access RRDtool's internal performance measurements.

+
+
use RRDp + +
+

Load the RRDp::pipe module.

+
+ +
RRDp::start path to RRDtool executable + +
+

start RRDtool. The argument must be the path to the RRDtool executable

+
+ +
RRDp::cmd rrdtool commandline + +
+

pass commands on to RRDtool. check the RRDtool documentation for +more info on the RRDtool commands.

+
+ +
$answer = 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.

+
+ +
$status = RRDp::end + +
+

terminates RRDtool and returns RRDtool's status ...

+
+ +
$RRDp::user, $RRDp::sys, $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.

+
+ +
$RRDp::error_mode and $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;
+
+ +
+

+

+
+

EXAMPLE

+
+ use RRDp;
+ RRDp::start "/usr/local/bin/rrdtool";
+ RRDp::cmd   qw(create demo.rrd --step 100 
+               DS:in:GAUGE:100:U:U
+               RRA:AVERAGE:0.5:1:10);
+ $answer = RRDp::read;
+ print $$answer;
+ ($usertime,$systemtime,$realtime) =  ($RRDp::user,$RRDp::sys,$RRDp::real);
+

+

NAME

+

RRDs - Access RRDtool as a shared module

+

+

+
+

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 ...
+

+

+
+

DESCRIPTION

+

+

+

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 AT-STYLE TIME SPECIFICATION format +used by RRDtool. See the rrdfetch documentation for a detailed +explanation on how to specify time.

+

+

+

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;
+

+

+

Return Values

+

The functions RRDs::last, RRDs::graph, RRDs::info, RRDs::fetch and RRDs::times +return their findings.

+

RRDs::last returns a single INTEGER representing the last update time.

+
+ $lastupdate = RRDs::last ...
+

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);
+

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";
+ }
+

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.

+

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";
+  }
+

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.

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();

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) +\& Octal (8) +\& Decimal (10) +\& Hexadecimal (16) +.Ve +.PP +.Vb 23 +\& (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 +.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. +.Ve +.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: +.PP +.Vb 16 +\& 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 +.Ve +.PP +Write down the results from right to left: \f(CW%1010000001000101\fR +.PP +Group by four: +.PP +.Vb 4 +\& %1010000001000101 +\& %101000000100 0101 +\& %10100000 0100 0101 +\& %1010 0000 0100 0101 +.Ve +.PP +Convert into hexadecimal: 0xA045 +.PP +Group \f(CW%1010000001000101\fR by three and convert into octal: +.PP +.Vb 8 +\& %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 +.Ve +.PP +.Vb 3 +\& So: %1010000001000101 = 0120105 = 0xA045 = 41029 +\& Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029(10) +\& Or: 1010000001000101(2) = 120105(8) = A045(16) = 41029 +.Ve +.PP +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: +.PP +.Vb 1 +\& %1010 + %0111 \-\-> 10 + 7 \-\-> 17 \-\-> %00010001 +.Ve +.PP +will become +.PP +.Vb 10 +\& %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 +.Ve +.PP +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 calculi in +other bases as easily as you do them in decimal. +.PP +When the numbers get bigger, you'll have to realize that a computer is +not called a computer just to have a nice name.

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.

+

+ 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
+

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 calculi 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 +different 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->accessories->calculator) +and if necessary click view->scientific. You now have a scientific +calculator and can compute in binary or hexadecimal.

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 + + +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.

This system uses ten sym- + bols 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 posi- + tion 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 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.

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 +.Vb 1 +\& date \-d "19990917 00:35:57" +%s +.Ve +.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".

NAME

cdeftutorial - Alex van den Bogaerdt's CDEF tutorial

+

+

+
+

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 +<alex@ergens.op.het.net>

+

+

+

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.

+

+

+

More reading

+

If you have difficulties with the way I try to explain it please read +Steve Rader's the rpntutorial manpage. It may help you understand how this all works.

+

+

+
+

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.

+

+

+
+

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)!

+

+

+
+

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:

+
    +
  1. +

    Start with an empty stack

    +
    2. +
  2. +

    Put the content of variable inbytes on the stack

    +
    3. +
  3. +

    Put the number eight on the stack

    +
    4. +
  4. +

    Put the operation multiply on the stack

    +
    5. +
  5. +

    Process the stack

    +
    6. +
  6. +

    Retrieve the value from the stack and put it in variable inbits

    +
    7. +
+

We will now do an example with real numbers. Suppose the variable +inbytes would have value 10, the stack would be:

+
    +
  1. +

    ||

    +
    2. +
  2. +

    |10|

    +
    3. +
  3. +

    |10|8|

    +
    4. +
  4. +

    |10|8|*|

    +
    5. +
  5. +

    |80|

    +
    6. +
  6. +

    ||

    +
    7. +
+

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.

+

+

+
+

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:

+

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 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 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 +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.

+

+

+
+

Some special numbers

+

+

+

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:

+
    +
  1. +

    The updates are too far apart. This is tuned using the ``heartbeat'' setting.

    +
    2. +
  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.

    +
    3. +
+

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.

+

+

+

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 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.

+

+

+

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.

+

+

+

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.

+

+

+
+

Some examples

+

+

+

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:

+
    +
  • +

    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 the rrdgraph manpage 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.

+

+

+

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:

+
    +
  • +

    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 +values 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. +
  2. +

    If the value is a known value, leave it as is.

    +
    3. +
  3. +

    Change the unknown value into zero.

    +
    4. +
+

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.

+

+

+

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:

+
    +
  1. +

    If the number exceeds 100kb/s it is wrong and you want it masked out +by changing it into unknown.

    +
    2. +
  2. +

    You don't want the graph to show more than 100kb/s.

    +
    3. +
+

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
+

+

+

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.

+

+

+

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
+

+

+

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:

+
    +
  • +

    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"
+

+

The examples from the RRD graph manual page

+

+

+

Degrees Celsius vs. Degrees Fahrenheit

+

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

+
+   rrdtool graph demo.png --title="Demo Graph" \
+      DEF:cel=demo.rrd:exhaust:AVERAGE \
+      CDEF:far=9,5,/,cel,*,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
+   
+=head2 Changing unknown into zero
+
+   rrdtool graph demo.png --title="Demo Graph" \
+      DEF:idat1=interface1.rrd:ds0:AVERAGE \
+      DEF:idat2=interface2.rrd:ds0:AVERAGE \
+      DEF:odat1=interface1.rrd:ds1:AVERAGE \
+      DEF:odat2=interface2.rrd:ds1:AVERAGE \
+      CDEF:agginput=idat1,UN,0,idat1,IF,idat2,UN,0,idat2,IF,+,8,* \
+      CDEF:aggoutput=odat1,UN,0,odat1,IF,odat2,UN,0,odat2,IF,+,8,* \
+      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.

Infinity demo

+

+      STACK:val4#FFC000:Value4 \
+      AREA:whipeout#FF0000:Unknown
+

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,*''

+

+

+

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'
+

+

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 +Ealex@ergens.op.het.netE + +=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. 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 + +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 + +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 + +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 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 will evaluate in +C<((((d+e)+c)+b)+a)> and it has the same outcome as C. +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. 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 +Another expression that would return the same: C + +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. 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 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 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 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 + +We now combine them: C and when we fill in the +appropriate things for "a" and "b" we're finished: + +C + +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 + +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.

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.

It may help you understand how this all + works. + +WWhhaatt aarree CCDDEEFFss?? + 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. + +SSyynnttaaxx + 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)! + +RRPPNN--eexxpprreessssiioonnss + 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. + +CCoonnvveerrttiinngg yyoouurr wwiisshheess ttoo RRPPNN + 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. + +SSoommee ssppeecciiaall nnuummbbeerrss + TThhee uunnkknnoowwnn vvaalluuee + + 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. + + WWoorrkkiinngg wwiitthh uunnkknnoowwnn ddaattaa iinn yyoouurr ddaattaabbaassee + + 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. + + IInnffiinniittyy + + 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 + it sure allows for some neat tricks. See below for examples. + + WWoorrkkiinngg wwiitthh uunnkknnoowwnn ddaattaa aanndd iinnffiinniittyy + + 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. + +SSoommee eexxaammpplleess + EExxaammppllee:: uussiinngg aa rreecceennttllyy ccrreeaatteedd RRRRDD + + 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. + + EExxaammppllee:: bbeetttteerr hhaannddlliinngg ooff uunnkknnoowwnn ddaattaa,, bbyy uussiinngg ttiimmee + + 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. + + EExxaammppllee:: PPrreetteennddiinngg wweeiirrdd ddaattaa iissnn''tt tthheerree + + 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 + + EExxaammppllee:: wwoorrkkiinngg oonn aa cceerrttaaiinn ttiimmee ssppaann + + 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.

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 ...

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.

NAME

+

rpntutorial - Reading RRDtool RPN Expressions by Steve Rader

+

+

+
+

DESCRIPTION

+

This tutorial should help you get to grips with RRDtool RPN expressions +as seen in CDEF arguments of RRDtool graph.

+

+

+
+

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.

+

+

+
+

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.

+

+

+
+

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)
+

+

+
+

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
+    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.)

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!

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. +.PP +Values of different variables can be presented in 5 different shapes +in a graph \- \s-1AREA\s0, \s-1LINE1\s0, \s-1LINE2\s0, \s-1LINE3\s0, and \s-1STACK\s0. \s-1AREA\s0 is represented +by a solid colored area with values as the boundary of this +area. \s-1LINE1/2/3\s0 (increasing width) are just plain lines representing +the values. \s-1STACK\s0 is also an area but it is \*(L"stack\*(R"ed on top \s-1AREA\s0 or +\&\s-1LINE1/2/3\s0. 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 \s-1STACK\s0 only after defining \s-1AREA/LINE\s0. It +is also possible to put formatted comments within the graph. Detailed +instructions can be found in the graph manual. +.Sh "Wrapping RRDtool within Shell/Perl script" +.IX Subsection "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.

SYNOPSIS

+

Helping new RRDtool users to understand the basics of RRDtool

+

+

+
+

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.

+

+

+

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:

+
    +
  • +

    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.

    +
    • +
  • +

    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.

    +
    • +
  • +

    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.

    +
    • +
  • +

    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.

    +
    • +
+

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.

+

+

+

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 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 step +seconds so that it updates the database every 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
+

DS 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 (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.

+

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 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 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 step +number of PDPs. This RRA will hold 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.

+

+

+

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.

+

+

+

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:

+

+

+

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
+

+

+

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)

+ 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

+ }

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. 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 +number of PDPs. This RRA will hold I 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.

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" fea- + ture of RRDtool. At the end, it has sample scripts that illustrate the + usage/wrapping of RRDtool within Shell or Perl scripts. + + WWhhaatt mmaakkeess RRRRDDttooooll ssoo ssppeecciiaall?? + + 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: + + · 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 cre- + ate graphs. + + · 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 RRD- + tool database always remains constant. The name "Round Robin" stems + from this behavior. + + · Other databases store the values as supplied. RRDtool can be con- + figured to calculate the rate of change from the previous to the + current value and store this information instead. + + · Other databases get updated when values are supplied. The RRDtool + database is structured in such a way that it needs data at prede- + fined 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. + + 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 vari- + ous 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. + + UUnnddeerrssttaannddiinngg bbyy aann eexxaammppllee + + 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 Func- + tion (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 _t_a_r_g_e_t_._r_r_d. 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 + sstteepp seconds so that it updates the database every sstteepp 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 + + DDSS 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 + ((PPDDPP)). 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. + + DDSSTT (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 + _c_h_a_n_g_e 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 hheeaarrttbbeeaatt. 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.

NAME

+

rrdbuild - Instructions for building RRDtool

+

+

+
+

DESCRIPTION

+

+

+

Overview

+

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.

+

+

+

Building

+

Before you start to build RRDtool, you have to decide two things:

+
    +
  1. +

    In which directory you want to build the software.

    +
    2. +
  2. +

    Where you want to install the software.

    +
    3. +
+

Once you have decided. Save the two locations into environment variables. +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 /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 +tar and make are actually GNU tar and GNU make respectively. It +could be that they are installed as gtar and gmake 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 +configure 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 -dev +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.

+

+

+

Build Tipps for AIX

+

If you are woking with AIX, you may find the the --disable-shared 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 --disable-static +instead.

+

Another hint to get rrdtool working on AIX is to use the IBM XL C Compiler:

+
+ export CC=/usr/vac/bin/cc
+ export PERLCC=$CC
+

(Better instructions for AIX welcome!)

+

+

+

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 CFLAGS +you want to set. The examples below are for the popular GCC compiler suite. +If you have an other compile you have to use the following 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 likley) 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 $BUILD_DIR
+ wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.10.tar.gz
+ tar zxvf libpng-1.2.10.tar.gz
+ cd libpng-1.2.10
+ env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
+     ./configure --disable-shared --prefix=$BUILD_DIR/lb
+ make
+ make install
+
+ +
Building freetype + +
+
+ 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$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \
+     ./configure --disable-shared --prefix=$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
+
+
Building libart_lgpl + +
+
+ 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
+
+
+

Now all the dependent libraries are built and you can try again. Since these +are static libraries, you may have to use ranlib to make them accessible. +Especially BSD systems like Mac OS X may require this, Linux and Solaris +will do just fine without since their ar command does ranlibs job as well.

+
+ ranlib $BUILD_DIR/lb/lib/*.a
+

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:

+
+ 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
+

If you are running bash/sh/ash/ksh/zsh use this:

+
+ 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
+

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.

+
+ cd $BUILD_DIR/rrdtool-1.2.26
+ ./configure --prefix=$INSTALL_DIR --disable-python --disable-tcl
+ make clean
+ make
+ make install
+

SOLARIS HINT: 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!

+

Now go to $INSTALL_DIR/share/rrdtool/examples/ and run them to see if your +build has been successful.

+

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 _/_t_m_p 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 $BUILD_DIR + + Lets first assume you already have all the necessary libraries + pre-installed. Note that these instructions assume that your copies of + ttaarr and mmaakkee are actually GGNNUU ttaarr and GGNNUU mmaakkee respectively. It could + be that they are installed as ggttaarr and ggmmaakkee on your system. + + wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.26.tar.gz + tar zxf rrdtool-1.2.26.tar.gz + cd rrdtool-1.2.26 + ./configure --prefix=$INSTALL_DIR && make && make install + + Ok, this was very optimistic. This try will probably have ended with + ccoonnffiigguurree 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 + --ddeevv 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. + + _B_u_i_l_d _T_i_p_p_s _f_o_r _A_I_X + + If you are woking with AIX, you may find the the ----ddiissaabbllee--sshhaarreedd + 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 + ----ddiissaabbllee--ssttaattiicc 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!) + + BBuuiillddiinngg LLiibbrraarriieess + + 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 $BUILD_DIR + wget http://oss.oetiker.ch/rrdtool/pub/libs/libpng-1.2.10.tar.gz + tar zxvf libpng-1.2.10.tar.gz + cd libpng-1.2.10 + env CPPFLAGS="-I$BUILD_DIR/lb/include" LDFLAGS="-L$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \ + ./configure --disable-shared --prefix=$BUILD_DIR/lb + make + make install + + Building freetype + 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$BUILD_DIR/lb/lib" CFLAGS="-O3 -fPIC" \ + ./configure --disable-shared --prefix=$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 + + Building libart_lgpl + 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 + + Now all the dependent libraries are built and you can try again. Since + these are static libraries, you may have to use _r_a_n_l_i_b to make them + accessible. Especially BSD systems like Mac OS X may require this, + Linux and Solaris will do just fine without since their _a_r command does + ranlibs job as well. + + ranlib $BUILD_DIR/lb/lib/*.a + + This time you tell configure where it should be looking for libraries + and include files. This is done via environment variables. Depending on + the shell you are running, the syntax for setting environment variables + is different. Under csh/tcsh you use: + + set IR=-I$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 + + If you are running bash/sh/ash/ksh/zsh use this: + + 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 + + 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. + + cd $BUILD_DIR/rrdtool-1.2.26 + ./configure --prefix=$INSTALL_DIR --disable-python --disable-tcl + make clean + make + make install + + SOLARIS HINT: 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 bind- + ings/perl-shared/Makefile while building! + + Now go to _$_I_N_S_T_A_L_L___D_I_R//sshhaarree//rrrrddttooooll//eexxaammpplleess// and run them to see if + your build has been successful. + +AAUUTTHHOORR + Tobias Oetiker + + + +1.2.26 2007-11-20 RRDBUILD(1) diff --git a/doc/rrdcgi.1 b/doc/rrdcgi.1 new file mode 100644 index 0000000..5be0d12 --- /dev/null +++ b/doc/rrdcgi.1 @@ -0,0 +1,336 @@ +.\" Automatically generated by Pod::Man v1.37, Pod::Parser v1.32 +.\" +.\" Standard preamble: +.\" ======================================================================== +.de Sh \" Subsection heading +.br +.if t .Sp +.ne 5 +.PP +\fB\\$1\fR +.PP +.. +.de Sp \" Vertical space (when we can't use .PP) +.if t .sp .5v +.if n .sp +.. +.de Vb \" Begin verbatim text +.ft CW +.nf +.ne \\$1 +.. +.de Ve \" End verbatim text +.ft R +.fi +.. +.\" Set up some character translations and predefined strings. \*(-- will +.\" give an unbreakable dash, \*(PI will give pi, \*(L" will give a left +.\" double quote, and \*(R" will give a right double quote. \*(C+ will +.\" give a nicer C++.

NAME

+

rrdcgi - Create web pages containing RRD graphs based on templates

+

+

+
+

SYNOPSIS

+

#!/path/to/rrdcgi [--filter]

+

+

+
+

DESCRIPTION

+

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 +<RRD:: tags. rrdcgi will interpret and act according to these tags. +In the end it will printout a web page including the necessary CGI headers.

+

rrdcgi 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.

+
+
--filter + +
+

Assume that rrdcgi is run as a filter and not as a cgi.

+
+ +
+

+

+

Keywords

+
+
RRD::CV name + +
+

Inserts the CGI variable of the given name.

+
+ +
RRD::CV::QUOTE 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.

+
+ +
RRD::CV::PATH 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.

+
+ +
RRD::GETENV 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.

+
+ +
RRD::GOODFOR 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 negative a Refresh header.

+
+ +
RRD::INCLUDE filename + +
+

Include the contents of the specified file into the page returned from the cgi.

+
+ +
RRD::SETENV variable 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.

+
+ +
RRD::SETVAR variable value + +
+

Analog to SETENV but for local variables.

+
+ +
RRD::GETVAR variable + +
+

Analog to GETENV but for local variables.

+
+ +
RRD::TIME::LAST rrd-file strftime-format + +
+

This gets replaced by the last modification time of the selected RRD. The +time is strftime-formatted with the string specified in the second argument.

+
+ +
RRD::TIME::NOW strftime-format + +
+

This gets replaced by the current time of day. The time is +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.

+
+ +
RRD::TIME::STRFTIME START|END start-spec end-spec strftime-format + +
+

This gets replaced by a strftime-formatted time using the format +strftime-format on either start-spec or end-spec depending on +whether START or END is specified. Both start-spec and 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 +argument to a GRAPH command.

+
+ +
RRD::GRAPH rrdgraph arguments + +
+

This tag creates the RRD graph defined by its argument and then is +replaced by an appropriate <IMG ... > tag referring to the graph. +The --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 RRD::GRAPH tag work as described in the rrdgraph manual page.

+
+
+

Use the --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 --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.

+
+ +
RRD::PRINT number + +
+

If the preceding RRD::GRAPH tag contained and PRINT arguments, +then you can access their output with this tag. The number argument refers to the +number of the PRINT argument. This first PRINT has number 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.

+
+ +
+

+

+
+

EXAMPLE 2

+

This script is slightly more elaborate, it allows you to run it from +a form which sets RRD_NAME. RRD_NAME is then used to select which RRD +you want to use as source for your graph.

Its purpose +is to run as a cgi-program and parse a web page template containing special +ERRD:: tags. B will interpret and act according to these tags. +In the end it will printout a web page including the necessary CGI headers. + +B 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. + +=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 + +Inserts the CGI variable of the given name. + +=item RRD::CV::QUOTE I + +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 + +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 + +Get the value of an environment variable. + + + +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 + +Specify the number of seconds this page should remain valid.

Both I and I +must be supplied as either could be relative to the other.

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.

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.

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.

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 \fR +.PP +.Vb 35 +\& time| +\& axis| +\& begin__|00| +\& |01| +\& u|02|\-\-\-\-* sample1, restart "hb"\-timer +\& u|03| / +\& u|04| / +\& u|05| / +\& u|06|/ "hbt" expired +\& u|07| +\& |08|\-\-\-\-* sample2, restart "hb" +\& |09| / +\& |10| / +\& u|11|\-\-\-\-* sample3, restart "hb" +\& u|12| / +\& u|13| / +\& step1_u|14| / +\& u|15|/ "swt" expired +\& u|16| +\& |17|\-\-\-\-* sample4, restart "hb", create "pdp" for step1 = +\& |18| / = unknown due to 10 "u" labled secs > "hb" +\& |19| / +\& |20| / +\& |21|\-\-\-\-* sample5, restart "hb" +\& |22| / +\& |23| / +\& |24|\-\-\-\-* sample6, restart "hb" +\& |25| / +\& |26| / +\& |27|\-\-\-\-* sample7, restart "hb" +\& step2__|28| / +\& |22| / +\& |23|\-\-\-\-* sample8, restart "hb", create "pdp" for step1, create "cdp" +\& |24| / +\& |25| / +.Ve +.PP +graphics by \fIvladimir.lavrov@desy.de\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.

NAME

+

rrdcreate - Set up a new Round Robin Database

+

+

+
+

SYNOPSIS

+

rrdtool create filename +[--start|-b start time] +[--step|-s step] +[DS:ds-name:DST:dst arguments] +[RRA:CF:cf arguments]

+

+

+
+

DESCRIPTION

+

The create function of RRDtool lets you set up new Round Robin +Database (RRD) files. The file is created at its final, full size +and filled with *UNKNOWN* data.

+
+
filename + +
+

The name of the RRD you want to create. RRD files should end +with the extension .rrd. However, RRDtool will accept any +filename.

+
+ +
--start|-b start time (default: now - 10s) + +
+

Specifies the time in seconds since 1970-01-01 UTC when the first +value should be added to the RRD. RRDtool will not accept +any data timed before or at the time specified.

+
+
+

See also AT-STYLE TIME SPECIFICATION section in the +rrdfetch documentation for other ways to specify time.

+
+ +
--step|-s step (default: 300 seconds) + +
+

Specifies the base interval in seconds with which data will be fed +into the RRD.

+
+ +
DS:ds-name:DST:dst arguments + +
+

A single RRD can accept input from several data sources (DS), +for example incoming and outgoing traffic on a specific communication +line. With the DS configuration option you must define some basic +properties of each data source you want to store in the RRD.

+
+
+

ds-name is the name you will use to reference this particular data +source from an RRD. A ds-name must be 1 to 19 characters long in +the characters [a-zA-Z0-9_].

+
+
+

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:

+
+
+

DS:ds-name:GAUGE | COUNTER | DERIVE | ABSOLUTE:heartbeat:min:max

+
+
+

For COMPUTE data sources, the format is:

+
+
+

DS:ds-name:COMPUTE: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.

+
+
+
GAUGE + +
+

is for things like temperatures or number of people in a room or the +value of a RedHat share.

+
+ +
COUNTER + +
+

is for continuous incrementing counters like the ifInOctets counter in +a router. The 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.

+
+ +
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.

+
+
+
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.

+
+ +
+
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.

+
+ +
COMPUTE + +
+

is for storing the result of a formula applied to other data sources +in the 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.

+
+ +
+

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 *UNKNOWN*.

+

min and max define the expected range values for data supplied by a +data source. If min and/or max any value outside the defined range +will be regarded as *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-COUNTER type DS this would be +the maximum and minimum data-rate expected from the device.

+

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.

+

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 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 CDEFs must refer only to DEFs +and CDEFs previously defined in the same graph command.

+
RRA:CF:cf arguments + +
+

The purpose of an RRD is to store data in the round robin archives +(RRA). An archive consists of a number of data values or statistics for +each of the defined data-sources (DS) and is defined with an RRA line.

+
+
+

When data is entered into an RRD, it is first fit into time slots +of the length defined with the -s option, thus becoming a primary +data point.

+
+
+

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

+
+
+

RRA:AVERAGE | MIN | MAX | LAST:xff:steps:rows

+
+
+

xff The xfiles factor defines what part of a consolidation interval may +be made up from *UNKNOWN* data while the consolidated value is still +regarded as known. It is given as the ratio of allowed *UNKNOWN* PDPs +to the number of PDPs in the interval. Thus, it ranges from 0 to 1 (exclusive).

+
+
+

steps defines how many of these primary data points are used to build +a consolidated data point which then goes into the archive.

+
+
+

rows defines how many generations of data values are kept in an RRA.

+
+ +
+

+

+
+

Aberrant Behavior Detection with Holt-Winters Forecasting

+

In addition to the aggregate functions, there are a set of specialized +functions that enable RRDtool to provide data smoothing (via the +Holt-Winters forecasting algorithm), confidence bands, and the +flagging aberrant behavior in the data source time series:

+
    +
  • +

    RRA:HWPREDICT:rows:alpha:beta:seasonal period[:rra-num]

    +
    • +
  • +

    RRA:SEASONAL:seasonal period:gamma:rra-num

    +
    • +
  • +

    RRA:DEVSEASONAL:seasonal period:gamma:rra-num

    +
    • +
  • +

    RRA:DEVPREDICT:rows:rra-num

    +
    • +
  • +

    RRA:FAILURES:rows:threshold:window length:rra-num

    +
    • +
+

These RRAs differ from the true consolidation functions in several ways. +First, each of the RRAs is updated once for every primary data point. +Second, these 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 RRA and SEASONAL RRA. Aberrant behavior +detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEASONAL.

+

The actual predicted, or smoothed, values are stored in the HWPREDICT +RRA. The predicted deviations are stored in DEVPREDICT (think a standard +deviation which can be scaled to yield a confidence band). The FAILURES +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 RRAs to graph confidence bounds and failures +appears in the rrdgraph manpage.

+

The SEASONAL and DEVSEASONAL 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 RRAs, the RRDtool create command supports +implicit creation of the other four when HWPREDICT is specified alone and +the final argument rra-num is omitted.

+

rows specifies the length of the 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, rows should be larger than +the seasonal period. If the DEVPREDICT RRA is implicitly created, the +default number of rows is the same as the HWPREDICT rows argument. If the +FAILURES RRA is implicitly created, rows will be set to the seasonal +period argument of the HWPREDICT RRA. Of course, the RRDtool +resize command is available if these defaults are not sufficient and the +creator wishes to avoid explicit creations of the other specialized function +RRAs.

+

seasonal period specifies the number of primary data points in a seasonal +cycle. If SEASONAL and DEVSEASONAL are implicitly created, this argument for +those RRAs is set automatically to the value specified by HWPREDICT. If +they are explicitly created, the creator should verify that all three +seasonal period arguments agree.

+

alpha is the adaption parameter of the intercept (or baseline) +coefficient in the Holt-Winters forecasting algorithm. See the rrdtool manpage for a +description of this algorithm. 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.

+

beta is the adaption parameter of the slope (or linear trend) coefficient +in the Holt-Winters forecasting algorithm. beta must lie between 0 and 1 +and plays the same role as alpha with respect to the predicted linear +trend.

+

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 RRAs are created +implicitly, they will both have the same value for gamma: the value +specified for the HWPREDICT 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 RRAs are created explicitly, gamma need not +be the same for both. Note that gamma can also be changed via the +RRDtool tune command.

+

rra-num provides the links between related RRAs. If HWPREDICT is +specified alone and the other RRAs are created implicitly, then +there is no need to worry about this argument. If RRAs are created +explicitly, then carefully pay attention to this argument. For each +RRA which includes this argument, there is a dependency between +that RRA and another RRA. The rra-num argument is the 1-based +index in the order of RRA creation (that is, the order they appear +in the create command). The dependent RRA for each RRA +requiring the rra-num argument is listed here:

+
    +
  • +

    HWPREDICT rra-num is the index of the SEASONAL RRA.

    +
    • +
  • +

    SEASONAL rra-num is the index of the HWPREDICT RRA.

    +
    • +
  • +

    DEVPREDICT rra-num is the index of the DEVSEASONAL RRA.

    +
    • +
  • +

    DEVSEASONAL rra-num is the index of the HWPREDICT RRA.

    +
    • +
  • +

    FAILURES rra-num is the index of the DEVSEASONAL RRA.

    +
    • +
+

threshold is the minimum number of violations (observed values outside +the confidence bounds) within a window that constitutes a failure. If the +FAILURES RRA is implicitly created, the default value is 7.

+

window length 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 RRA is implicitly created, the +default value is 9.

+

+

+
+

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. -- Don Baarda <don.baarda@baesystems.com>

HOW TO MEASURE

+

Here are a few hints on how to measure:

+
+
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 +GAUGE 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 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 +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.

+
+ +
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).

+
+ +
+

+

+
+

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 RRD called temperature.rrd which accepts one +temperature value every 300 seconds. If no new data is supplied for +more than 600 seconds, the temperature becomes *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.

+

+

+
+

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 RRA tracks the +traffic flow in octets; the second RRA generates the specialized +functions RRAs for aberrant behavior detection. Note that the rra-num +argument of HWPREDICT is missing, so the other 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 RRA.

+

The same RRD file and RRAs are created with the following command, +which explicitly creates all specialized function 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.

+

+

+
+

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 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.

With the B configuration option you must define some basic +properties of each data source you want to store in the B. + +I is the name you will use to reference this particular data +source from an B. A I must be 1 to 19 characters long in +the characters [a-zA-Z0-9_]. + +I defines the Data Source Type. The remaining arguments of a +data source entry depend on the data source type.

The B 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.

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.

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 + +is for counters which get reset upon reading.

Aberrant behavior +detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEASONAL. + +The actual predicted, or smoothed, values are stored in the HWPREDICT +B. The predicted deviations are stored in DEVPREDICT (think a standard +deviation which can be scaled to yield a confidence band). The FAILURES +B 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 to graph confidence bounds and failures +appears in L. + +The SEASONAL and DEVSEASONAL B 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, the B create command supports +implicit creation of the other four when HWPREDICT is specified alone and +the final argument I is omitted. + +I specifies the length of the B 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 should be larger than +the I. If the DEVPREDICT B is implicitly created, the +default number of rows is the same as the HWPREDICT I argument. If the +FAILURES B is implicitly created, I will be set to the I argument of the HWPREDICT B. Of course, the B +I command is available if these defaults are not sufficient and the +creator wishes to avoid explicit creations of the other specialized function +B. + +I specifies the number of primary data points in a seasonal +cycle. If SEASONAL and DEVSEASONAL are implicitly created, this argument for +those B is set automatically to the value specified by HWPREDICT. If +they are explicitly created, the creator should verify that all three +I arguments agree. + +I is the adaption parameter of the intercept (or baseline) +coefficient in the Holt-Winters forecasting algorithm. See L for a +description of this algorithm. I 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 is the adaption parameter of the slope (or linear trend) coefficient +in the Holt-Winters forecasting algorithm. I must lie between 0 and 1 +and plays the same role as I with respect to the predicted linear +trend. + +I 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 are created +implicitly, they will both have the same value for I: the value +specified for the HWPREDICT I 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 are created explicitly, I need not +be the same for both. Note that I can also be changed via the +B I command. + +I provides the links between related B. If HWPREDICT is +specified alone and the other B are created implicitly, then +there is no need to worry about this argument. If B are created +explicitly, then carefully pay attention to this argument. For each +B which includes this argument, there is a dependency between +that B and another B. The I argument is the 1-based +index in the order of B creation (that is, the order they appear +in the I command). The dependent B for each B +requiring the I argument is listed here: + +=over + +=item * + +HWPREDICT I is the index of the SEASONAL B. + +=item * + +SEASONAL I is the index of the HWPREDICT B. + +=item * + +DEVPREDICT I is the index of the DEVSEASONAL B. + +=item * + +DEVSEASONAL I is the index of the HWPREDICT B. + +=item * + +FAILURES I is the index of the DEVSEASONAL B. + +=back + +I is the minimum number of violations (observed values outside +the confidence bounds) within a window that constitutes a failure. If the +FAILURES B is implicitly created, the default value is 7. + +I 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 B is implicitly created, the +default value is 9. + +=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.

The only connection is +that the temperature reading happened at a certain time. You can use the +B 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 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 called F 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 tracks the +traffic flow in octets; the second B generates the specialized +functions B for aberrant behavior detection. Note that the I +argument of HWPREDICT is missing, so the other B 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. + +The same RRD file and B are created with the following command, +which explicitly creates all specialized function B. + + 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.

Also consult the section on "HOW TO + MEASURE" for further insight. + + GGAAUUGGEE + is for things like temperatures or number of people in a + room or the value of a RedHat share. + + CCOOUUNNTTEERR + is for continuous incrementing counters like the ifInOctets + counter in a router. The CCOOUUNNTTEERR 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. + + DDEERRIIVVEE + 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 + + 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. + + AABBSSOOLLUUTTEE + 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. + + CCOOMMPPUUTTEE + is for storing the result of a formula applied to other + data sources in the RRRRDD. 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 + sets are referred to as "virtual" or "computed" columns. + + _h_e_a_r_t_b_e_a_t 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 _*_U_N_K_N_O_W_N_*. + + _m_i_n and _m_a_x define the expected range values for data supplied + by a data source.

First, each of the RRRRAAs is updated once for every primary data + point. Second, these RRRRAAss 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 RRRRAA and SEASONAL RRRRAA. Aberrant + behavior detection requires FAILURES, HWPREDICT, DEVSEASONAL, and SEA- + SONAL. + + The actual predicted, or smoothed, values are stored in the HWPREDICT + RRRRAA. The predicted deviations are stored in DEVPREDICT (think a stan- + dard deviation which can be scaled to yield a confidence band). The + FAILURES RRRRAA 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 RRRRAAss to graph confidence bounds + and failures appears in rrdgraph. + + The SEASONAL and DEVSEASONAL RRRRAAss 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 RRRRAAss, the RRRRDDttooooll create command supports + implicit creation of the other four when HWPREDICT is specified alone + and the final argument _r_r_a_-_n_u_m is omitted. + + _r_o_w_s specifies the length of the RRRRAA prior to wrap around.

Of course, the RRRRDDttooooll + _r_e_s_i_z_e command is available if these defaults are not sufficient and + the creator wishes to avoid explicit creations of the other specialized + function RRRRAAss. + + _s_e_a_s_o_n_a_l _p_e_r_i_o_d specifies the number of primary data points in a sea- + sonal cycle. If SEASONAL and DEVSEASONAL are implicitly created, this + argument for those RRRRAAss is set automatically to the value specified by + HWPREDICT. If they are explicitly created, the creator should verify + that all three _s_e_a_s_o_n_a_l _p_e_r_i_o_d arguments agree. + + _a_l_p_h_a 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. _a_l_p_h_a 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. + + _b_e_t_a is the adaption parameter of the slope (or linear trend) coeffi- + cient in the Holt-Winters forecasting algorithm. _b_e_t_a must lie between + 0 and 1 and plays the same role as _a_l_p_h_a with respect to the predicted + linear trend. + + _g_a_m_m_a 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 RRRRAAss are cre- + ated implicitly, they will both have the same value for _g_a_m_m_a: the + value specified for the HWPREDICT _a_l_p_h_a 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 RRRRAAss are created explicitly, _g_a_m_m_a need not + be the same for both. Note that _g_a_m_m_a can also be changed via the RRRRDD-- + ttooooll _t_u_n_e command. + + _r_r_a_-_n_u_m provides the links between related RRRRAAss. If HWPREDICT is speci- + fied alone and the other RRRRAAss are created implicitly, then there is no + need to worry about this argument. If RRRRAAss are created explicitly, then + carefully pay attention to this argument. For each RRRRAA which includes + this argument, there is a dependency between that RRRRAA and another RRRRAA. + The _r_r_a_-_n_u_m argument is the 1-based index in the order of RRRRAA creation + (that is, the order they appear in the _c_r_e_a_t_e command). The dependent + RRRRAA for each RRRRAA requiring the _r_r_a_-_n_u_m argument is listed here: + + · HWPREDICT _r_r_a_-_n_u_m is the index of the SEASONAL RRRRAA. + + · SEASONAL _r_r_a_-_n_u_m is the index of the HWPREDICT RRRRAA. + + · DEVPREDICT _r_r_a_-_n_u_m is the index of the DEVSEASONAL RRRRAA. + + · DEVSEASONAL _r_r_a_-_n_u_m is the index of the HWPREDICT RRRRAA. + + · FAILURES _r_r_a_-_n_u_m is the index of the DEVSEASONAL RRRRAA. + + _t_h_r_e_s_h_o_l_d is the minimum number of violations (observed values outside + the confidence bounds) within a window that constitutes a failure. If + the FAILURES RRRRAA is implicitly created, the default value is 7. + + _w_i_n_d_o_w _l_e_n_g_t_h 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 RRRRAA is implicitly cre- + ated, the default value is 9. + +TThhee HHEEAARRTTBBEEAATT aanndd tthhee SSTTEEPP + 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. _-_- _D_o_n _B_a_a_r_d_a _<_d_o_n_._b_a_a_r_d_a_@_b_a_e_s_y_s_t_e_m_s_._c_o_m_> + + time| + axis| + begin__|00| + |01| + u|02|----* sample1, restart "hb"-timer + u|03| / + u|04| / + u|05| / + u|06|/ "hbt" expired + u|07| + |08|----* sample2, restart "hb" + |09| / + |10| / + u|11|----* sample3, restart "hb" + u|12| / + u|13| / + step1_u|14| / + u|15|/ "swt" expired + u|16| + |17|----* sample4, restart "hb", create "pdp" for step1 = + |18| / = unknown due to 10 "u" labled secs > "hb" + |19| / + |20| / + |21|----* sample5, restart "hb" + |22| / + |23| / + |24|----* sample6, restart "hb" + |25| / + |26| / + |27|----* sample7, restart "hb" + step2__|28| / + |22| / + |23|----* sample8, restart "hb", create "pdp" for step1, create "cdp" + |24| / + |25| / + + graphics by _v_l_a_d_i_m_i_r_._l_a_v_r_o_v_@_d_e_s_y_._d_e. + +HHOOWW TTOO MMEEAASSUURREE + 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 GGAAUUGGEE 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 AABBSSOOLLUUTTEE 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). + +EEXXAAMMPPLLEE + 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 RRRRDD called _t_e_m_p_e_r_a_t_u_r_e_._r_r_d which accepts one tempera- + ture value every 300 seconds. If no new data is supplied for more than + 600 seconds, the temperature becomes _*_U_N_K_N_O_W_N_*. 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 first RRRRAA tracks + the traffic flow in octets; the second RRRRAA generates the specialized + functions RRRRAAss for aberrant behavior detection. Note that the _r_r_a_-_n_u_m + argument of HWPREDICT is missing, so the other RRRRAAss 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.

NAME

+

rrdfetch - Fetch data from an RRD.

+

+

+
+

SYNOPSIS

+

rrdtool fetch filename CF +[--resolution|-r resolution] +[--start|-s start] +[--end|-e end]

+

+

+
+

DESCRIPTION

+

The fetch function is normally used internally by the graph +function to get data from RRDs. fetch will analyze the RRD +and try to retrieve the data in the resolution requested. +The data fetched is printed to stdout. *UNKNOWN* data is often +represented by the string ``NaN'' depending on your OS's printf +function.

+
+
filename + +
+

the name of the RRD you want to fetch the data from.

+
+ +
CF + +
+

the consolidation function that is applied to the data you +want to fetch (AVERAGE,MIN,MAX,LAST)

+
+ +
--resolution|-r resolution (default is the highest resolution) + +
+

the interval you want the values to have (seconds per +value). rrdfetch will try to match your request, but it will return +data even if no absolute match is possible. NB. See note below.

+
+ +
--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 TIME SPECIFICATION +section for a detailed explanation on ways to specify the start time.

+
+ +
--end|-e 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.

+
+ +
+

+

+

RESOLUTION INTERVAL

+

In order to get RRDtool to fetch anything other than the finest resolution RRA +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 +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

+
    +
  1. +

    both start and end time are a multiple of 900

    +
    2. +
  2. +

    both start and end time are within the desired RRA

    +
    3. +
+

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"'
+

+

+

AT-STYLE TIME SPECIFICATION

+

Apart from the traditional 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 TIME REFERENCE +specification and the TIME OFFSET specification.

+

+

+

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 now. On its own part, +time reference consists of a time-of-day reference (which should come +first, if present) and a day reference.

+

The time-of-day can be specified as HH:MM, HH.MM, +or just HH. You can suffix it with am or pm or use +24-hours clock. Some special times of day are understood as well, +including midnight (00:00), noon (12:00) and British +teatime (16:00).

+

The day can be specified as month-name day-of-the-month and +optional a 2- or 4-digit year number (e.g. March 8 1999). Alternatively, +you can use day-of-week-name (e.g. Monday), or one of the words: +yesterday, today, tomorrow. You can also specify the day as a +full date in several numerical formats, including MM/DD/[YY]YY, +DD.MM.[YY]YY, or YYYYMMDD.

+

NOTE1: this is different from the original at(1) behavior, where a +single-number date is interpreted as MMDD[YY]YY.

+

NOTE2: if you specify the day in this way, the time-of-day is +REQUIRED as well.

+

Finally, you can use the words now, start, or end as your time +reference. Now refers to the current moment (and is also the default +time reference). Start (end) can be used to specify a time +relative to the start (end) time for those tools that use these +categories (rrdfetch, the rrdgraph manpage).

+

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 now, start, end can be abbreviated as n, s, e.

+

+

+

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 sign +(+ or -) and an amount. The following time units can be +used to specify the amount: years, months, weeks, days, +hours, minutes, or 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.)

+

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 (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 mktime(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 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, '8:00 Mar 27 1999 +2 +days' = '8:00 Mar 29 1999', but since there is 1-hour DST 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)

+

NOTE4: The single-letter abbreviation for both months and minutes +is m. To disambiguate them, the parser tries to read your mind :) +by applying the following two heuristics:

+
    +
  1. +

    If m is used in context of (i.e. right after the) years, +months, weeks, or days it is assumed to mean months, while +in the context of hours, minutes, and seconds it means minutes. +(e.g., in -1y6m or +3w1m m is interpreted as months, while in +-3h20m or +5s2m m the parser decides for minutes).

    +
    2. +
  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's 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)

    +
    3. +
+

Final NOTES: 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).

+

TIME SPECIFICATION EXAMPLES

+

Oct 12 -- October 12 this year

+

-1month or -1m -- current time of day, only a month before +(may yield surprises, see NOTE3 above).

+

noon yesterday -3hours -- yesterday morning; can also be specified +as 9am-1day.

+

23:59 31.12.1999 -- 1 minute to the year 2000.

+

12/31/99 11:59pm -- 1 minute to the year 2000 for imperialists.

+

12am 01/01/01 -- start of the new millennium

+

end-3weeks or e-3w -- 3 weeks before end time +(may be used as start time specification).

+

start+6hours or s+6h -- 6 hours after start time +(may be used as end time specification).

+

931225537 -- 18:45 July 5th, 1999 +(yes, seconds since 1970 are valid as well).

+

19970703 12:45 -- 12:45 July 3th, 1997 +(my favorite, and its even got an ISO number (8601)).

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 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, RRDtool does also +understand at-style time specification.
