+GNU General Public License (GPL)
+================================
+                   GNU GENERAL PUBLIC LICENSE
+                      Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser 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 noncommercial 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
+
+           How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    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.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it

+         runtime has been fixed.
+

+         for his patch.
+       * interface plugin: "mac" interfaces are now ignored on Solaris. These
+         pseudo-interfaces occur multiple times, causing warnings. Also switch
+         to 64-bit counters on Solaris, improving overflow behavior for
+         high-speed interfaces. Thanks to Eddy Geez and Fabien Wernli for
+         their patches.

+         have ended up using the modified name rather than the original name.
+         Thanks to Sebastian Harl for identifying the problem.
+       * oracle plugin: A memory leak has been fixed in the parameter handling.

+         instance, if it is empty. Compatibility with libyajl 2 has been
+         added. Thanks to "spupykin" of the Arch Linux project for the initial
+         code. Formatting of time has been fixed in the JSON module.

+         Thanks to Alexander Kovalenko for fixing this.
+       * iptables plugin: Fix linking with some versions of libiptc.

+         assumed that interrupts have a numeric value -- this is no longer
+         true for Linux. Thanks to Bostjan Skufca for implementing this.
+       * notify_desktop plugin: Compatibility with libnotify 0.7 has been
+         added. Thanks to Samuli Suominen for his patch.
+       * processes plugin: Fix handling of regular expressions containing

+         to Francois-Xavier Bourlet for fixing this.
+       * varnish plugin: Fix data type handling of some metrics. Some values
+         were submitted as gauge even though they were derives.
+       * Various plugin: Set a multi-threading flag in libcurl. Thanks to Mike
+         Flisher for the fix.

+         added to the collectd client library.

+         plugins such as the network plugin can still handle "counter", of
+         course. The minimum value of all derive data sources is zero, the
+         maximum value is unspecified.
+       * amqp plugin: The new AMQP plugin can send data to and receive data
+         from an AMQP broker. Thanks to Sebastien Pahl for his code.

+         under Solaris. Thanks to Jeff Blane for his help debugging this.
+       * collectd: A couple of memory leaks through PThread thread attributes
+         have been fixed. Thanks to Gerrie Roos for fixing these.

+       * oracle plugin: Error messages have been improved.
+       * ping plugin: Don't enter the exponential back-off mode when

+         patch.
+       * network plugin: Forwarding of notifications has been disabled. This
+         was a contition not checked for before, which may retult in an

+         added to the Linux implementation. Thanks to Darrell Bishop for his

+         for his patch.
+       * interface plugin: "mac" interfaces are now ignored on Solaris. These
+         pseudo-interfaces occur multiple times, causing warnings. Also switch
+         to 64-bit counters on Solaris, improving overflow behavior for
+         high-speed interfaces. Thanks to Eddy Geez and Fabien Wernli for
+         their patches.
+       * memory plugin: Account kernel and unused memory under Solaris. Thanks
+         to Fabien Wernli for his patch.
+       * network plugin: A bug in the interaction between the Network plugin
+         and filter chains has been fixed: When a filter modified a field such
+         as the hostname, subsequent values in the same network packets could
+         have ended up using the modified name rather than the original name.
+         Thanks to Sebastian Harl for identifying the problem.
+       * oracle plugin: A memory leak has been fixed in the parameter handling.

+         code.
+       * iptables plugin: Fix linking with some versions of libiptc.
+       * irq plugin: Fix support for interrupts under Linux. The old code

+         added. Thanks to Samuli Suominen for his patch.

+         Flisher for the fix.

+       * collectd: Handling of the `Include' configuration option has been
+         fixed.
+       * battery plugin: Don't complain about a missing directory every
+         interval.
+       * exec plugin: Allow executed programs to close STDERR. Thanks to
+         Thorsten von Eicken for reporting this problem.
+       * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
+         Tomasz Pala for the patch.
+       * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
+         the patch.
+       * memory plugin: Fix a potential problem under Solaris.
+       * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
+         to Doug MacEachern for the patch.
+
+2009-03-18, Version 4.6.2
+       * collectd: Some Solaris utility code has been improved.
+       * filter subsystem: Allow `Chains' without default targets.
+       * liboping: A patch to comply with strict aliasing rules has been
+         added.
+       * timediff match: Fix a typo: The match was registered with a wrong
+         name which prevented this match to be used as documented. Thanks to
+         Bruno Prémont for finding this problem.
+       * bind plugin: Fix collection of the cached RR sets. The number of RR
+         sets currently in the cache was collected as a counter value, which
+         is nonsense. Thanks to Bruno Prémont for implementing this.
+       * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
+         primarily BSDs, don't take it well and crash.
+       * oracle plugin: Portability to 64 bit systems has been improved.
+       * postgresql plugin: The default configuration has been improved.
+       * rrdtool plugin: Fix a possible race condition: If the network plugin
+         is brought and dispatches a value before the rrdtool plugin is
+         initialized, the daemon may crash.
+
+2009-02-22, Version 4.6.1
+       * collectd: Many documentation fixes.
+       * Collectd::Unixsock: Error handling has been improved.
+       * regex match: Don't link with the PCRE library.
+       * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
+         for finding and fixing most of them.
+       * ipmi plugin: Fix an off-by-one error which could cause segmentation
+         faults. Thanks to Peter Holik for his patch.
+
+2009-02-16, Version 4.6.0
+       * collectd: Added the `filter chain' infrastructure, which allows the
+         user to use `matches' and `targets' to control value processing.
+       * collectd: The new `-T' command line argument allows more in-depth
+         testing of a configuration. Thanks to Doug MacEachern for the patch.
+       * collectd-nagios: The Nagios integration command has been updated to
+         use libcollectdclient. The `percentage' aggregation function has
+         been added. Thanks to Fabian Linzberger for the patch.
+       * libcollectdclient: A library which abstracts communication with the
+         unixsock plugin for clients has been added.
+       * regex match: Match values by their identifies using regular
+         expressions.
+       * timediff match: Match for values with an invalid timestamp.
+       * value match: Select values by their data sources' values.
+       * notification target: Create and dispatch a notification.
+       * replace target: Replace parts of an identifier using regular
+         expressions.
+       * set target: Set (overwrite) entire parts of an identifier.
+       * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
+         statistics, allowing very detailed name server statistics. Thanks to
+         Bruno Prémont for this plugin.
+       * cpu plugin: Report `interrupt' separately when using
+         sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
+         example for native OpenBSD support, has been added. Thanks to Simon
+         Kuhnle for the patch.
+       * csv plugin: Make it possible to write values to STDOUT instead of
+         files. This is meant for testing purposes mostly. The output written
+         to STDOUT is compatible with the exec plugin. Thanks to Doug
+         MacEachern for the patch.
+       * curl plugin: This new plugin can be used to read web pages and parse
+         them using the same mechanism that's used in the tail plugin.
+       * dbi plugin: This new plugin allows you to connect to a variety of
+         relational databases and use SQL to gather custom statistics from
+         it. It is similar to the already existing PostgreSQL plugin but uses
+         libdbi to communicate with the database(s).
+       * interface plugin: Use the ignorelist framework when selecting /
+         ignoring interfaces. This allows one to use regular expressions to
+         select interfaces, too.
+       * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
+         Thanks to Bruno Prémont for this patch.
+       * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
+         for the patch.
+       * mysql plugin: Allow connecting to a database via the UNIX domain
+         socket, too. Thanks to Mirko Buffoni for the patch.
+       * network plugin: Further performance improvements for the receive
+         code. This hopefully will help very large setups.
+       * openvpn plugin: This new plugin collects statistics provided by the
+         OpenVPN daemon. Thanks to Doug MacEachern for the patch.
+       * oracle plugin: This new plugin allows you to connect to an Oracle
+         database and use SQL to gather custom statistics from it. It is
+         similar to the already existing PostgreSQL plugin.
+       * perl plugin: Compatibility fixes for broken versions of Perl 5.10
+         have been added.
+       * perl plugin: Export the newly added plugin_write() to Perl plugins.
+       * perl plugin: Added support for `notification meta data'.
+       * perl plugin: Added support for the `filter chain' infrastructure by
+         allowing plugins to register `matches' and `targets'.
+       * postgresql plugin: The preferred configuration syntax has been
+         updated to be in line with the syntax used by the new dbi and oracle
+         plugins. The compatibility code for the old syntax is present.
+         Support for the new `Result' blocks and the interval parameter has
+         been added.
+       * processes plugin: Stacksize and virtual memory usage statistics have
+         been added. Portability fixes.
+       * rrdcached plugin: This new plugin uses the (still in development)
+         RRD accelerator daemon, rrdcached. This daemon works very similar to
+         the original rrdtool plugin of collectd, but adds some more nice
+         features.
+       * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
+         added.
+
+2009-05-09, Version 4.5.4
+       * Build system, various plugins: Many build fixes for FreeBSD,
+         OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
+         for many fixes and providing a build system for many platforms,
+         Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
+         providing an OpenBSD system.
+       * collectd: Fix a potential race condition when creating directories.
+       * battery plugin: Don't complain about a missing directory every
+         interval.
+       * dns plugin: Slight portability fixes.
+       * exec plugin: Allow executed programs to close STDERR. Thanks to
+         Thorsten von Eicken for reporting this problem.
+       * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
+         Tomasz Pala for the patch.
+       * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
+         the patch.
+       * rrdtool plugin: Fix a possible race condition: If the network plugin
+         is initialized and dispatches a value before the rrdtool plugin is
+         initialized, the daemon may crash.
+       * memory plugin: Fix a potential problem under Solaris.
+
+2009-02-22, Version 4.5.3
+       * build system: The check for libupsclient even when `pkg-config' is
+         not available.
+       * collectd: Fix error handling in the global cache.
+       * Collectd::Unixsock: Error handling has been improved.
+       * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
+         patch.
+       * ipmi plugin: Fix an off-by-one error which could cause segmentation
+         faults. Thanks to Peter Holik for his patch.
+       * tcpconns plugin: An endianness problem has been fixed in the *BSD
+         code. Thanks to "thated" for reporting this.
+
+2009-01-02, Version 4.5.2
+       * build system: Check for `mysql.h' and `mysql/mysql.h', since the
+         file may be in both locations, especially when the database was
+         installed in a non-standard path. Thanks to Dusty Doris for
+         reporting this.
+       * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
+         Solaris, in the configure script automatically.
+       * build system, tcpconns plugin: Check for `kvm_nlist' and
+         `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
+         library with similar functions to the BSD variant, but doesn't
+         provide these necessary functions.
+       * collectd.conf(5): Various fixes and clarifications.
+       * collectd: Remove a GNUism (unnamed unions), thus improving
+         portability.
+       * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
+         This solves portability problems, especially for Solaris.
+       * dns plugin: Fix a portability problem with NetBSD.
+       * filecount plugin: Fix an off-by-one error. This error may cause a
+         segmentation fault.
+       * network plugin: Fix the handling of `type' in the network protocol.
+         Due to a programming mistake, only 4 or 8 bytes would be copied to a
+         much larger buffer. This caused the `type' to be transferred much
+         more often than necessary. In some cases, e. g. the `cpu' and
+         `cpufreq' plugins being used at the same time, data may be corrupted
+         in those files. Thanks to Bruno Prémont for debugging and reporting
+         this issue.
+       * processes plugin: Fix a possible segmentation fault when specifying
+         invalid configuration options.
+       * unixsock plugin: Make sure the initialization function is run only
+         once. This resolves a file descriptor leak under systems which run
+         the initialization more than once, such as Solaris.
+
+2008-10-16, Version 4.5.1
+       * build system: Change `--enable-<plugin>' to abort with an error if
+         dependencies are not met. Thanks to Bruno Prémont for the patch.
+         Also, the poisoning of various string functions has been restricted
+         to debug builds.
+       * collectd: Fix a memory leak in the global value cache. With every
+         *missing* value a couple of bytes would be leaked. Another memory
+         leak in the configuration handling code has been fixed. Thanks to
+         Niraj Tolia for reporting these issues.
+       * collectd: Fix an off-by-one error in the ignorelist functionality.
+         When using regular expressions, the last character would be missing,
+         possibly matching differently from what one would expect.
+       * collectdmon: Don't block SIGCHLD. This fixes a potential portability
+         problem.
+       * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
+         Linzberger for reporting the bug.
+       * iptables plugin: Fix an off-by-one error. If a string was just one
+         character too long, it was truncated instead of reporting an error.
+       * network plugin: Fix a memory leak in the configuration handling
+         code. Thanks to Niraj Tolia for reporting this issue.
+       * perl plugin: Log an error message if bootstrapping `Collectd' fails.
+       * postgresql plugin: Don't reopen connection during reinitialization.
+         This fixes a bug under Solaris and potentially other platforms.
+         Missing calls to `PQclear' have been added, too. This fixes memory
+         leaks. Thanks to ``Admin'' for reporting these bugs.
+       * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
+         library.
+       * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
+         problems with some `libc's. Thanks to Matthias Lay for reporting the
+         bug.
+
+2008-09-04, Version 4.5.0
+       * collectd: Added the ability to flush certain identifiers.
+       * collectd: The concept of `notification meta data' has been
+         introduced.
+       * filecount plugin: The new filecount plugin counts the number of
+         files in a directory and its subdirectories.
+       * ipmi plugin: Sensor names have been changed to ensure unique names.
+         Notifications upon added and removed sensors can now be generated.
+       * notify_desktop plugin: This new plugin sends notifications to the
+         X desktop using the structure defined in the `Desktop Notification
+         Specification'.
+       * notify_email plugin: This new plugin sends out notifications via
+         email, using the `esmtp' library.
+       * onewire plugin: The new experimental(!) onewire plugin reads values,
+         such as temperatures, from sensors connected to the computer via the
+         onewire bus.
+       * perl plugin: Improved synchronized access to internal data structures
+         and fixed a possible dead-lock.
+       * perl plugin: Added the ability to flush certain identifiers and marked
+         plugin_flush_all() and plugin_flush_one() as deprecated in favor of
+         plugin_flush().
+       * perl plugin: Added the ability to configure Perl plugins.
+       * postgresql plugin: The new postgresql plugin collects statistics
+         about or from a PostgreSQL database.
+       * processes plugin: The `ProcessMatch' option has been added.
+       * rrdtool plugin: Implement throttling of the `update queue' to lessen
+         IO load.
+       * tcpconns plugin: This plugin has been ported to OpenBSD.
+       * thermal plugin: The new thermal plugin collects system temperatures
+         using Linux ACPI thermal zone data.
+
+2009-01-02, Version 4.4.5
+       * build system: Check for `mysql.h' and `mysql/mysql.h', since the
+         file may be in both locations, especially when the database was
+         installed in a non-standard path. Thanks to Dusty Doris for

+
+2008-09-01, Version 4.4.3
+       * collectd: Fix a memory leak in the threshold checking code.
+       * memcached plugin: Fix a too short timeout and a related file
+         descriptor leak.

+         of disks.
+       * dns plugin: Fix compilation errors with BIND versions 19991001
+         through 19991005.
+       * network plugin: Bugfix in the init routine: The init function
+         cleared a buffer regardless of its contents. This could lead to lost
+         values under Solaris.
+       * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
+       * vserver plugin: Remove usage of the thread-unsafe `readdir'
+         function.
+       * wireless plugin: Work around incorrect noise and power values
+         returned by some broken drivers.
+
+2008-06-03, Version 4.4.1
+       * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
+         to kyrone for reporting this.
+       * collectd: Fixed min/max output in notifications generated by
+         threshold checking.
+       * collectd-nagios: Fix the protocol used to communicate with the
+         daemon.
+       * perl plugin: Fail noisily, but don't shutdown the daemon, if
+         initialization has errors. An issue with Perl 5.10 has been fixed.
+       * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
+         René Rebe and Siegmund Gorr for reporting this.
+
+2008-05-06, Version 4.4.0
+       * collectd: Internal code cleanups.
+       * collectd: Added support for a `Flush' command in the unixsock and
+         exec plugins. This command can be used to force a plugin (or all) to
+         flush its values to disk.
+       * collectd: Thresholds can now be configured to apply to one data
+         source only, making it possible to configure different thresholds
+         for each data source.
+       * apache, nginx plugins: Added the possibility to disable host and/or
+         peer verification.
+       * ascent plugin: The new ascent plugin reads and parses the statistics

+       * iptables plugin: The iptc library that is used by the iptables
+         plugin has been added to the distribution, because it is not
+         provided by all distributions and removed from at least one.
+       * powerdns plugin: The new powerdns plugin reads statistics from an
+         authoritative or a recursing PowerDNS name server.
+       * rrdtool plugin: The size of the files generated with the default
+         configuration has been decreased.
+       * tail plugin: The new tail plugin can be used to gather statistics by
+         continuously reading from log files.
+       * teamspeak2 plugin: The new teamspeak2 plugin connects to a
+         TeamSpeak2 server and collects statistics about the number of users
+         and number of channels.
+       * users plugin: Support for the statgrab library has been added.
+       * vmem plugin: The new vmem plugin collects very detailed statistics
+         about the virtual memory subsystem of Linux.

+         under Solaris.
+       * nginx plugin: A thread-unsafe function has been replaced.
+       * vserver plugin: A thread-unsafe function has been replaced.
+       * wireless plugin: A work-around for broken wireless drivers has been
+         added.
+
+2008-04-22, Version 4.3.3
+       * build system: Improved detection of several libraries, especially if
+         they are in non-standard paths.
+       * build system: Portability fixes: Automatically define "_REENTRANT"
+         if the libc expects it.
+       * collectd: Error and warning messages have been improved.
+       * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
+         using them.
+       * apache plugin: Allocate new memory when reading a webpage instead of
+         using a buffer of static size.
+       * exec plugin: Close (almost) all filedescriptors before exec(2)ing
+         the program.
+       * hddtemp plugin: Error and warning messages have been improved.
+       * sensors plugin: Fix sensor collection for some chip types.

+2008-03-29, Version 4.3.2
+       * collectd: Fix configuration of the `FailureMax', `WarningMax', and
+         `Persist' threshold options.
+       * collectd: Fix handling of missing values in the global value cache.
+       * collectd: Improved error messages when parsing the configuration.
+       * sensors plugin: Fix temperature collection with libsensors4.
+       * unixsock plugin: Fix mixed input and output operation on streams.
+       * wireless plugin: Fix reading noise value.
+
+2008-03-05, Version 4.3.1
+       * exec plugin: Set supplementary group IDs.
+       * network plugin:
+         + Use `memcpy' when constructing/parsing a package to avoid
+           alignment problems on weird architectures, such as Sparc.
+         + Translate doubles to/from the x86 byte representation to ensure
+           cross-platform compatibility.
+       * ping plugin: Correct the handling of the `TTL' setting.
+       * swap plugin: Reapply a patch for Solaris.
+       * tcpconns plugin: Portability improvements.
+
+2008-02-18, Version 4.3.0
+       * collectd: Notifications have been added to the daemon. Notifications
+         are status messages that may be associated with a data instance.
+       * collectd: Threshold checking has been added to the daemon. This
+         means that you can configure threshold values for each data
+         instance. If this threshold is exceeded a notification will be
+         created.
+       * collectd: The new `FQDNLookup' option tells the daemon to use the
+         full qualified domain name as the hostname, not just the host part
+         es returned by `gethostname(2)'.
+       * collectd: Support for more than one `TypesDB' file has been added.
+         This is useful when one such file is included in a package but one
+         wants to add custom type definitions.
+       * collectd: The `Include' config option has been expanded to handle
+         entire directories and shell wildcards.
+       * collectdmon: The new `collectdmon' binary detects when collectd
+         terminates and automatically restarts it again.
+       * csv plugin: The CSV plugin is now able to store counter values as a
+         rate, using the `StoreRates' configuration option.
+       * exec plugin: Handling of notifications has been added and the
+         ability to pass arguments to the executed programs has been added.
+       * hddtemp plugin: The new `TranslateDevicename' option lets you
+         disable the translation from device names to major-minor-numbers.
+       * logfile plugin: Handling of notifications has been added.
+       * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
+         domain name lookups in this plugin.
+       * perl plugin: Many internal changes added support for handling multiple
+         threads making the plugin reasonably usable inside collectd. The API has
+         been extended to support notifications and export global variables to
+         Perl plugins; callbacks now have to be identified by name rather than a
+         pointer to a subroutine. The plugin is no longer experimental.
+       * uuid plugin: The new UUID plugin sets the hostname to an unique
+         identifier for this host. This is meant for setups where each client
+         may migrate to another physical host, possibly going through one or
+         more name changes in the process. Thanks to Richard Jones from
+         Red Hat's Emerging Technology group for this plugin.
+       * libvirt: The new libvirt plugin uses the `libvirt' library to query
+         CPU, disk and network statistics about guest systems on the same
+         physical server. Thanks to Richard Jones from Red Hat's Emerging
+         Technology group for this plugin.
+
+2008-04-22, Version 4.2.7
+       * build system: Improved detection of several libraries, especially if
+         they are in non-standard paths.
+       * build system: Portability fixes: Automatically define "_REENTRANT"
+         if the libc expects it.
+       * collectd: Error and warning messages have been improved.
+       * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
+         using them.
+       * apache plugin: Allocate new memory when reading a webpage instead of
+         using a buffer of static size.
+       * exec plugin: Close (almost) all filedescriptors before exec(2)ing
+         the program.
+       * hddtemp plugin: Error and warning messages have been improved.
+       * sensors plugin: Fix sensor collection for some chip types.
+
+2008-03-29, Version 4.2.6
+       * collectd: Improved error messages when parsing the configuration.
+       * sensors plugin: Fix temperature collection with libsensors4.
+       * unixsock plugin: Fix mixed input and output operation on streams.
+       * wireless plugin: Fix reading noise value.
+
+2008-03-04, Version 4.2.5
+       * apache plugin: Improved initialization and error messages.
+       * exec plugin: Set supplementary group IDs.
+       * network plugin:
+         + Create separate threads for reading from the socket and parsing
+           and dispatching incoming packets. Versions prior to this may have
+           problems in high-load situations, where the socket receive buffers
+           overflows, resulting in gaps in the data.
+         + Use `memcpy' when constructing/parsing a package to avoid
+           alignment problems on weird architectures, such as Sparc.
+         + Translate doubles to/from the x86 byte representation to ensure
+           cross-platform compatibility.
+       * ping plugin: Correct the handling of the `TTL' setting.
+       * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
+       * swap plugin: Reapply a patch for Solaris.
+       * tcpconns plugin: Portability improvements.
+
+2008-01-21, Version 4.2.4
+       * unixsock plugin: A bug in the unixsock plugin caused it not to set
+         the permission on the socket as documented in the manpage. Thanks to
+         Evgeny Chukreev for fixing this issue.
+       * collectd: The documentation has been improved.
+
+2007-12-28, Version 4.2.3
+       * sensors plugin: Updated the plugin to build and work with version 3
+         of the libsensors library.
+
+2007-12-15, Version 4.2.2
+       * nginx plugin: Incorrect comparison of strings lead to a segfault
+         when using the plugin. Thanks to Saulius Grigaliunas for fixing
+         this.
+       * logfile plugin: The config option `Timestamp' was handled
+         incorrectly and basically always active. Thanks to Luke Heberling
+         for fixing this.
+
+2007-11-08, Version 4.2.1
+       * tcpconns plugin: Don't complain about a missing file if IPv6 is not
+         enabled on the host.
+       * snmp plugin: Fix a memory leak.
+
+2007-10-27, Version 4.2.0
+       * collectd: The new config option `Include' lets you include other
+         configfiles and thus split up your config into smaller parts. This
+         may be especially interesting for the snmp plugin to keep the data
+         definitions separate from the host definitions.
+       * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
+         (number of connections, octets and packets for each service and
+         destination). Thanks to Sebastian Harl for this plugin.
+       * memcached plugin: The new `memcached' plugin connects to a memcached
+         daemon process and collects statistics of this distributed caching
+         system. Thanks to Antony Dovgal for contributing this plugin.
+       * nginx plugin: The new `nginx' plugin reads the status page of an
+         nginx daemon and saves the handled connections and requests.
+       * perl plugin: Many changes, including the added `EnableDebugger'
+         config option which lets you debug your Perl plugins more easily.
+       * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
+         be more thread-safe otherwise by locking calls to the library.
+       * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
+         correct the values returned by SNMP-agents. If a <data> block is
+         defined as `table' the instance is now optional. The sequence number
+         is used as the type-instance in this case. The new `InstancePrefix'
+         option allows to add arbitrary prefixes to the type-instance.
+       * tcpconns plugin: The new `tcpconns' plugin collects the number of
+         certain TCP connections and what state they're in. This can be used
+         to see how many connections your FTP server has to handle or how
+         many outgoing connections your mailserver has open.
+
+2008-01-11, Version 4.1.6
+       * unixsock plugin: A bug in the unixsock plugin caused it not to set
+         the permission on the socket as documented in the manpage. Thanks to
+         Evgeny Chukreev for fixing this issue.
+       * collectd: The documentation has been improved.
+
+2007-12-27, Version 4.1.5
+       * rrdtool plugin: Fix a memory leak that only occurred in very-low-
+         memory situations.
+       * sensors plugin: Updated the plugin to build and work with version 3
+         of the libsensors library.
+
+2007-11-08, Version 4.1.4
+       * Build system: Improve detection of the rrd library, especially if
+         it's in a non-standard location.
+       * Build system: A bug when parsing the argument for
+         `--with-libnetsnmp' has been fixed.
+       * collectd: Implement `strerror_r' if the libc doesn't provide it.
+       * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
+         a deadlock or delay when shutting down the daemon.
+       * snmp plugin: Fix a memory leak.
+
+2007-10-24, Version 4.1.3
+       * collectd: A build issue under Solaris has been resolved by renaming
+         data types.
+       * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
+         be more thread-safe otherwise by locking calls to the library.
+
+2007-09-28, Version 4.1.2
+       * apcups plugin: Fix reporting of the `load percent' data.
+       * wireless plugin: Correct the handling of cards returning signal and
+         noise quality as percentage.
+       * perl plugin: Fix a possible buffer overflow in get_module_name().
+       * build system: Further improve the detection of libraries.
+       * netlink plugin: Build issues under some older versions of the Linux
+         includes (i. e. Debian Sarge) have been fixed.
+       * snmp plugin: Fix a potential segfault when a host times out. Add
+         support for the `timeticks' type. 
+
+2007-09-12, Version 4.1.1
+       * Build system: The detection of `libnetlink' has been improved.
+       * collectd: The documentation has been fixed in numerous places.
+       * exec plugin: Setting the group under which to run a program has been
+         fixed.
+       * collectd: The `sstrerror' function was improved to work correctly
+         with the broken GNU version of `strerror_r'.
+       * collectd: Write an error message to STDERR when loading of a plugin
+         fails.
+       * apcups plugin: Fix the `types' used to submit the values: They still
+         has an `apcups_' prefix which doesn't work anymore.
+       * rrdtool plugin: Create new RRD-files with the `begin' time set to
+         whatever the client thinks is `now'..
+
+2007-09-01, Version 4.1.0
+       * Build system: The build system has been changed to automatically
+         disable all plugins, which are missing dependencies. The dependency
+         checking has been removed from the plugins themselves to remove
+         redundancy.
+       * Flexible interval: The interval of collected data is now sent along
+         with the data itself over the network, so that the interval-settings
+         of server and clients no longer needs to match.
+       * netlink plugin: The new `netlink' plugin connects to the Linux
+         kernel using a netlink socket and uses it to query information about
+         interfaces, qdiscs and classes.
+       * rrdtool plugin: The cache is now dumped to disk in an extra thread
+         to not block data collection.
+       * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
+         network devices, such as switches, routers, thermometers, rack
+         monitoring servers, etc. The collectd-snmp(5) manpage documents this
+         plugin.
+       * unixsock plugin: Added the `LISTVAL' command.
+       * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
+         of music played with xmms.
+
+2007-09-28, Version 4.0.9
+       * apcups plugin: Fix reporting of the `load percent' data.
+       * wireless plugin: Correct the handling of cards returning signal and
+         noise quality as percentage.
+       * perl plugin: Fix a possible buffer overflow in get_module_name().
+
+2007-09-12, Version 4.0.8
+       * collectd: The `sstrerror' function was improved to work correctly
+         with the broken GNU version of `strerror_r'.
+       * collectd: Write an error message to STDERR when loading of a plugin
+         fails.
+       * apcups plugin: Fix the `types' used to submit the values: They still
+         has an `apcups_' prefix which doesn't work anymore.
+       * rrdtool plugin: Create new RRD-files with the `begin' time set to
+         whatever the client thinks is `now'..
+
+2007-08-26, Version 4.0.7
+       * documentation: Some typos have been fixed and some information has
+         been improved.
+       * build system: Many fixes for detecting libraries in unusual places,
+         such as on RedHat systems. The affected libraries are `libcurl',
+         `libmysql', and `libupsclient'.
+       * network plugin: Allow the `Port' option to be specified as a number
+         (i. e. without quotes).
+       * nut plugin: A fix allows linking the nut plugin against
+         libupsclient, version >= 2.2.0.
+       * processes plugin: Fix a potential segmentation fault.
+
+2007-07-30, Version 4.0.6
+       * sensors plugin: Fix the ignorelist functionality: Only the `type
+         instance' was used to match against the list, but the documentation
+         told otherwise. This release fixes the code, so it complies with the
+         documentation.
+       * syslog plugin: Call `openlog' right when the plugin is loaded, so
+         configuration messages will end up in the logging facility.
+       * conrtib/fedora: The contributed specfile for Fedora has been
+         updated.
+
+2007-07-05, Version 4.0.5
+       * Portability: More fixes for OpenBSD have been included.
+
+2007-06-24, Version 4.0.4
+       * cpu plugin: Fixed the Solaris code.
+       * dns plugin: Fixed a build issue for OpenBSD.
+       * interface plugin: Fixed the Solaris code.
+       * load plugin: Fixed the alternative `/proc' Linux code.
+       * memory plugin: Fixed the Solaris code.
+       * oconfig: Don't require `-lfl' anymore.
+
+2007-06-19, Version 4.0.3
+       * cpu plugin: Fix the Darwin / Mac OS X code.
+       * ping plugin: Use the return value of `getpid', not its address.
+       * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
+         initialized correctly.
+       * configure: Added `--with-nan-emulation' to aid cross compilation.
+
+2007-06-12, Version 4.0.2
+       * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
+         they're given in numerically form.
+
+2007-06-07, Version 4.0.1
+       * iptables plugin: A bug in the configuration routine has been fixed.
+         Setting a comment in the configfile will no longer cause a
+         segmentation fault.
+
+2007-06-03, Version 4.0.0
+       * collectd: The plugin-infrastructure has been changed to allow for
+         more types of plugins, namely `write' and `log' plugins.
+       * collectd: The read-function has been changed to read many plugins in
+         parallel, using threads. Thus, plugins generally need to use
+         thread-safe functions from now on.
+       * collectd: The '-t' command line options allows to perform syntax tests
+         of the configuration file and exit immediately.
+       * csv plugin: The new `csv' plugin handles output to `comma separated
+         values'-files.
+       * rrdtool plugin: The new `rrdtool' plugin handles output to
+         RRD-files. Data can be cached to combine multiple updates into one
+         write to increase IO-performance.
+       * network plugin: The new `network' plugin handles IO via the network.
+         It implements a different, much more extensible protocol which can
+         combine many values in one packet, decreasing the number of UDP-
+         packets being sent. It can read from and send to the network and
+         with the appropriate configuration even forward packets to other
+         networks.
+       * unixsock plugin: The new `unixsock' plugin provides an interface to
+         communicate with the daemon while it is running. Right now the
+         commands `GETVAL' and `PUTVAL' are implemented, but more are to
+         come.
+       * perl plugin: The new `perl' plugin allows you to write extensions
+         for collectd in the scripting-language Perl.
+       * logfile plugin: The new `logfile' plugin writes logmessages to files
+         or STDOUT or STDERR.
+       * syslog plugin: The new `syslog' plugin sends logmessages to the
+         system's syslog daemon.
+       * entropy plugin: The new `entropy' plugin collects the amount of
+         entropy currently being available to the system.
+       * exec plugin: The new `exec' plugin forks child processes and reads
+         back values provided by the forked processes.
+       * iptables plugin: The new `iptables' plugin reads counters from
+         iptables rules. Thanks to Sjoerd van der Berg for contributing this
+         plugin.
+       * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
+         to Peter Holik for contributing this plugin.
+       * nut plugin: The new `nut' plugin connects the upsd of the `network
+         ups tools' and reads information about the connected UPS.
+       * apache plugin: Support for lighttpd's `BusyServers' (aka.
+         connections) field was added by Florent Monbillard.
+       * collectd-nagios: The new `collectd-nagios' binary queries values
+         from collectd, parses them and exits according to Nagios-standards.
+       * manpages: The manpages have been improved a lot.
+
+2007-09-28, Version 3.11.7
+       * wireless plugin: Correct the handling of cards returning signal and
+         noise quality as percentage.
+
+2007-08-31, Version 3.11.6
+       * processes plugin: Fix a potential segmentation fault.
+
+2007-05-29, Version 3.11.5
+       * configure: Added `AC_SYS_LARGEFILE' for LFS.
+       * ntpd plugin: Fix a potential buffer overflow.
+       * processes plugin: Fix a bug when run under Linux 2.4. All processes
+         were accounted as `zombies'.
+
+2007-04-10, Version 3.11.4
+       * dns plugin: Change the order of includes to make the plugin compile
+         under FreeBSD.
+
+2007-03-30, Version 3.11.3
+       * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
+         of the unused `COLLECT_KSTAT'.
+
+2007-02-11, Version 3.11.2
+       * plugin: Catch NULL-pointer and try to fix them. Otherwise the
+         NULL-pointer may have been passed to `printf' which causes a
+         segfault with some libcs.
+
+2007-02-10, Version 3.11.1
+       * df plugin: Some wrong defines have been fixed so the plugin works
+         under Solaris again.
+       * dns plugin: The usage of a struct has been fixed to work with
+         non-GNU libcs.
+       * processes plugin: Some missing defines have been added so the plugin
+         compiles cleanly under FreeBSD and presumably other UNIXes.
+
+2006-12-22, Version 3.11.0
+       * collectd: The new command line option `-P' makes it easier for
+         distributors to change the location of PID-files.
+       * collectd: The daemon shuts down faster now which makes it easier to
+         write init.d-scripts for it.
+       * apache plugin: Increase the buffersize to 16k, because the 4k buffer
+         caused problems every now and then.
+       * df plugin: New config options allow to ignore certain mountpoints,
+         filesystem types or devices.
+       * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
+         and interprets it. It collects traffic as well as qtype, opcode and
+         rcode counts.
+       * email plugin: Sebastian Harl has contributed this plugin which
+         counts received mails in categories (e. g. ham, spam, virus), spam
+         score (as given by SpamAssassin) and check types.
+       * mbmon plugin: Flavio Stanchina has contributed this plugin which
+         uses `mbmon' to gather information from sensors on the motherboard.
+       * processes plugin: Collect detailed statistics for configured
+         processes, that's process and thread count, CPU usage, resident
+         segment size and pagefaults.
+       * multimeter plugin: Peter Holik contributed a new plugin which
+         queries multimeters.
+       * sensors plugin: Lubos Stanek has put much effort into improving this
+         plugin, including `extended naming', collection of voltage values
+         and the possibility to ignore certain values.
+
+2006-12-21, Version 3.10.4
+       * Max Kellermann has identified a bug in the server routine: When
+         opening a socket fails the daemon will (re)try opening the socket in
+         an endless loop, ultimately leading to a `EMFILE' error.
+
+2006-11-04, Version 3.10.3
+       * Lubos Stanek has identified a bug in the ntpd-plugin: When the
+         ntpd's reply was sent in more than one packet, the buffer size was
+         calculated incorrectly, resulting in the reading of uninitialized or
+         freed memory.
+
+2006-11-01, Version 3.10.2
+       * The sample config file has been improved.
+       * Errors in the manpages have been corrected.
+       * The ping-plugin now adds hosts during initialization, not during
+         startup. This speeds up startup when no network connectivity is
+         available. Also, the hosts are being added later when the network is
+         available.
+       * Improved BSD-support for the df-plugin.
+       * Fixed syntax errors in the swap-plugin for Mac OS X.
+       * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
+         plugin.
+       * Don't disable the mysql-plugin if connecting to the database fails
+         during initialization. Instead, try again in increasing intervals.
+
+2006-07-19, Version 3.10.1
+       * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
+         the apcups cannot be reached, unconnected sockets will pile up and
+         eventually lead to `Too many open files' errors.
+
+2006-07-09, Version 3.10.0
+       * The `disk' plugin has been ported to Darwin.
+       * The `battery' plugin should work on many Apple computers now.
+       * The `traffic' plugin can now ignore certain interfaces. Also,
+         statistics for sent/received packets and errors have been added.
+       * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
+         to Anthony Gialluca for contributing this plugin and providing me
+         with a test environment :)
+       * A plugin for monitoring an NTP instance and the local clock drift
+         has been added.
+
+2006-06-25, Version 3.9.4
+       * The Solaris code in the `swap' plugin has been changed to reflect
+         the numbers returned by `swap -s'. Thanks to Christophe Kalt for
+         working this out.
+       * The debugging system has been fixed to work with the Sun libc.
+       * When built without librrd the variable `operating_mode' could be
+         uninitialized. Thanks to David Elliot for reporting the bug.
+
+2006-06-01, Version 3.9.3
+       * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
+         operating systems also profit from the changes, but I wasn't able to
+         check that.
+       * Changed the build system to find the netinet-includes under FreeBSD
+         and therefore successfully build the `liboping' library there.
+
+2006-05-09, Version 3.9.2
+       * Applied a patch to the `liboping' library. Due to a bug in the
+         sequence checking the `ping' plugin stopped working after
+         approximately 7.6 days.
+
+2006-05-09, Version 3.8.5
+       * Applied a patch to the `liboping' library. Due to a bug in the
+         sequence checking the `ping' plugin stopped working after
+         approximately 7.6 days.
+
+2006-04-21, Version 3.9.1
+       * Build issues with Solaris and possible other architectures have been
+         resolved.
+       * Problems when building the `apache'-plugin without `libcurl' have
+         been resolved.
+       * A bug in the `ping' plugin has been fixed. Sorry folks.
+
+2006-04-02, Version 3.9.0
+       * A plugin to monitor the Apache webserver has been added.
+         <http://httpd.apache.org/>
+       * A plugin to collect statistics about virtual servers using VServer.
+         <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
+         this plugin :)
+       * A plugin for wireless LAN cards has been added. It monitors signal
+         strength, link quality and noise ratio..
+       * A plugin for Apple hardware sensors has been added.
+       * An option to compile collectd with different `step' and `heartbeat'
+         settings has been added. The size of RRAs is no longer static but
+         calculated based on the settings for `step' and `width'.
+       * The `ping' plugin can now be configured to use a certain TTL.
+       * A plugin to monitor the hardware sensors of Apple computers has been
+         added.
+       * The plugins `cpu', `memory', `processes' and `traffic' have been
+         ported to Mach/Darwin (Mac OS X).
+       * The `log mode' has been contributed by Christophe Kalt. It writes
+         the data into text files rather than RRD files.
+
+2006-04-09, Version 3.8.4
+       * Applied patch by Vincent Stehlé which improves the disk-name
+         resolution in the `hddtemp' plugin for Linux systems.
+
+2006-04-02, Version 3.8.3
+       * Applied a patch by James Byers: The MySQL plugin was not working
+         with MySQL 5.0.2 or later.
+
+2006-03-14, Version 3.8.2
+       * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
+         the GNU libc, because it points to `/etc/fstab' rather than
+         `/etc/mtab'.
+
+2006-03-13, Version 3.8.1
+       * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
+       * Fixes in the debian `postinst' and `init.d' scripts.
+
+2006-03-09, Version 3.8.0
+       * The `ping' plugin no longer uses `libping' but a self written
+         library named `liboping'. With this library it's possible to ping
+         multiple IPv4 and IPv6 addresses and hostnames - in parallel.
+
+2006-02-18, Version 3.7.2
+       * A simple bug in the `battery' plugin has been fixed. It should now
+         work with ACPI based batteries as well. Thanks to Sebastian for
+         fixing this.
+       * Fixing a bug that prevented collectd to be built without librrd.
+         Thanks to Werner Heuser for reporting it.
+
+2006-02-04, Version 3.7.1
+       * The new network code has been improved to build with older versions
+         of glibc.
+       * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
+         to Tommie Gannert for this patch.
+
+2006-01-30, Version 3.7.0
+       * The `battery' plugin has been added. It collects information about
+         laptop batteries..
+       * The MySQL plugin has been improved: It now writes two more RRD
+         files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
+       * The `cpufreq' plugin now reads another file since the file it did
+         read so far causes much overhead in the kernel. Also, you need root
+         to read the old file, but not to read the new one.
+       * The `hddtemp' plugin can now be configured to connect to another
+         address and/or port than localhost.
+       * The `df' plugin now prefers `statvfs' over `statfs'.
+       * The network code has been rewritten. collectd now supports unicast
+         and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
+         be set in the configfile.
+
+2006-01-24, Version 3.6.2
+       * Due to a bug in the configfile handling collectd wouldn't start in
+         client mode. This released fixes this.
+
+2006-01-20, Version 3.6.1
+       * Due to a bug in `configure.in' all modules and the binary were
+         linked against `libmysqlclient'. This issue is solved by this
+         release.
+
+2006-01-17, Version 3.6.0
+       * A config file has been added. This allows for loading only specific
+         plugins.
+       * A `df' plugin has been added.
+       * A `mysql' plugin has been added.
+       * The `ping' plugin doesn't entirely give up hope when a socket error
+         occurred, but will back of and increase the intervals between tries.
+
+2006-01-21, Version 3.5.2
+       * Fixed yet another bug in the signal handling.. Stupid typo..
+       * Improved the ping plugin to not give up on socket errors (backport
+         from 3.6.0).
+
+2005-12-18, Version 3.5.1
+       * The PID-file is now deleted correctly when shutting down the daemon.
+       * SIGINT and SIGTERM are now handled correctly.
+
+2005-12-16, Version 3.5.0 (Revision 326)
+       * A bug in the `load' module under Solaris has been fixed.
+       * The `users' module has been contributed by Sebastian Harl. It counts
+         currently logged in users.
+       * The CPU module now works under FreeBSD without the use of
+         `libstatgrab', however SMP support is missing.
+       * The default directories for the RRD files and the PID file now
+         depend on the compile time setting of `localstatedir'.
+
+2005-11-15, Version 3.4.0 (Revision 236)
+       * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
+         from gentoo's bugzilla for writing the patch.
+       * The build dependency for librrd has been removed. Binaries built
+         without librrd are client-only and will multicast their value as
+         with the `-c' argument.
+       * A patch by Peter Holik adds a module for monitoring CPU frequencies.
+       * The newly introduced `-f' switch prevents daemon initialization
+         (forking, closing standard filehandles, etc.) Thanks to Alvaro
+         Barcellos for this patch.
+
+2005-11-04, Version 3.3.0 (Revision 216)
+       * New modules have been added:
+         - `serial', for monitoring traffic on the serial interfaces
+         - `nfs', for graphing NFS procedure calls
+         - `tape', traffic from/to tape devices
+       * The memory.rrd now accepts more than 4Gig of memory.
+
+2005-10-26, Version 3.2.0 (Revision 200)
+       * Support for graphing the processes has been added (thanks to Lyonel
+         Vincent)
+       * If reading from hddtemp fails collectd will increase the time
+         between polls up to one day.
+       * The init.d files have been improved.
+       * Problems with the spec file have been fixed.
+
+2005-10-16, Version 3.1.0 (Revision 194)
+       * Added the `setsid' syscall to the startup code.
+       * Support for hddtemp has been added (thanks to Vincent Stehlé)
+
+2005-09-30, Version 3.0.0 (Revision 184)
+       * The ability to send/receive data to/from the network (think
+         multicast) has been added.
+       * Modules have been split up into shared libraries can be loaded at
+         runtime. The biggest advantage is that the core program doesn't need
+         to be linked against an external library.
+       * A patch by George Kargiotakis has been applied: It fixes the sensors
+         behaviour then more than one sensor is being queried.
+
+2005-09-16, Version 2.1.0 (Revision 172)
+       * A module for swap statistics has been added.
+
+2005-09-09, Version 2.0.0 (Revision 135)
+       * Filenames can no longer be configured at program startup. The only
+         options as of this version are the directory and ping hosts.
+       * CPU statistics now include Wait-IO. If provided under Linux IRQ and
+         Soft-IRQ statistics are added to `System'. 
+       * Diskstats now collect read and write bytes, not sectors.
+       * Ping statistics can now be collected for more than one host. There
+         is no default any more: If no host is given no host will be pinged.
+       * A self-written patch for libping has been applied so it builds
+         cleanly.
+
+2005-09-01, Version 1.8.1 (Revision 123)
+       * Much improved configure-script: libraries and features may now be
+         disabled.
+       * More detailed warnings/error messages when RRD update fails.
+
+2005-08-29, Version 1.8.0:
+       * Support for collecting disk statistics under Solaris.
+
+2005-08-25, Version 1.7.0:
+       * Support for libstatgrab[1] for load, memory usage and network
+         traffic. CPU- and disk-usage are not (yet) supported, since
+         libstatgrab returns insufficient information. I will contact the
+         authors.
+       * Improved the CPU-initialization code for Solaris. Apparently CPUs
+         aren't necessarily counted linear which is now handled correctly.
+       [1]: http://www.i-scream.org/libstatgrab/
+
+2005-08-21, Version 1.6.0:
+       * Basic support for Solaris: System load and cpu-usage can be
+         collected under Solaris, too. Other stats will follow later.
+       * Many fixes in the autoconf-script
+       * Collection/Museum scripts have been added under contrib/museum
+       * collectd may now be started in unprivileged mode, though ping
+         statistics will not work.
+
+2005-07-17, Version 1.5.1:
+       * Diskstats-RRDs now use major/minor for naming. Some systems have
+         weird strings as disk-names..
+
+2005-07-17, Version 1.5:
+       * A new module, diskstats, has been added. It collects information
+         about the disks and partitions.
+
+2005-07-11, Version 1.4.2:
+       * The meminfo module has been changed to work with more platforms
+         and/or kernel versions.
+
+2005-07-10, Version 1.4.1: Correct traffic stats
+       * The traffic rrd-file is now created with DS-type `COUNTER' which I
+         forgot to correct when I changed that module.
+
+2005-07-09, Version 1.4: More traffic stats
+       * Traffic is now collected for all interfaces that can be found
+       * Temperature-statistics are read from lm-sensors if available
+
+2005-07-08, Version 1.3: CPU stats
+       * Collecting CPU statistics now
+
+2005-07-12, Version 1.2: Using syslog
+       * collectd is now using the syslog facility to report errors, warnings
+         and the like..
+       * The default directory is now /var/db/collectd
+
+2005-07-10, Version 1.1: Minor changes
+       * Nothing really useful to say ;)
+
+2005-07-09, Version 1.0: Initial Version
+       * The following modules are provided:
+         * Load average
+         * Ping time
+         * Traffic
+         * Memory info

+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================

+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+    - perl
+      Of course the values are propagated to plugins written in Perl, too, so
+      you can easily do weird stuff with the plugins we didn't dare think of
+      ;) See collectd-perl(5).
+
+    - python
+      It's possible to implement write plugins in Python using the python
+      plugin. See collectd-python(5) for details.
+
+    - rrdcached
+      Output to round-robin-database (RRD) files using the RRDtool caching
+      daemon (RRDcacheD) - see rrdcached(1). That daemon provides a general
+      implementation of the caching done by the `rrdtool' plugin.
+
+    - rrdtool
+      Output to round-robin-database (RRD) files using librrd. See rrdtool(1).
+      This is likely the most popular destination for such values. Since
+      updates to RRD-files are somewhat expensive this plugin can cache
+      updates to the files and write a bunch of updates at once, which lessens
+      system load a lot.
+
+    - unixsock
+      One can query the values from the unixsock plugin whenever they're
+      needed. Please read collectd-unixsock(5) for a description on how that's
+      done.
+
+    - write_graphite
+      Sends data to Carbon, the storage layer of Graphite using TCP or UDP. It
+      can be configured to avoid logging send errors (especially useful when
+      using UDP).
+
+    - write_http
+      Sends the values collected by collectd to a web-server using HTTP POST
+      requests. The transmitted data is either in a form understood by the
+      Exec plugin or formatted in JSON.
+
+    - write_kafka
+      Sends data to Apache Kafka, a distributed queue.
+
+    - write_log
+      Writes data to the log
+
+    - write_mongodb
+      Sends data to MongoDB, a NoSQL database.
+
+    - write_redis
+      Sends the values to a Redis key-value database server.
+
+    - write_riemann
+      Sends data to Riemann, a stream processing and monitoring system.
+
+    - write_sensu
+      Sends data to Sensu, a stream processing and monitoring system, via the
+      Sensu client local TCP socket.
+
+    - write_tsdb
+      Sends data OpenTSDB, a scalable no master, no shared state time series
+      database.
+
+  * Logging is, as everything in collectd, provided by plugins. The following
+    plugins keep up informed about what's going on:
+
+    - logfile
+      Writes log messages to a file or STDOUT/STDERR.
+
+    - perl
+      Log messages are propagated to plugins written in Perl as well.
+      See collectd-perl(5).
+
+    - python
+      It's possible to implement log plugins in Python using the python plugin.
+      See collectd-python(5) for details.
+
+    - syslog
+      Logs to the standard UNIX logging mechanism, syslog.
+
+    - log_logstash
+      Writes log messages formatted as logstash JSON events.
+
+  * Notifications can be handled by the following plugins:
+
+    - notify_desktop
+      Send a desktop notification to a notification daemon, as defined in
+      the Desktop Notification Specification. To actually display the
+      notifications, notification-daemon is required.
+      See http://www.galago-project.org/specs/notification/.
+
+    - notify_email
+      Send an E-mail with the notification message to the configured
+      recipients.
+
+    - exec
+      Execute a program or script to handle the notification.
+      See collectd-exec(5).
+
+    - logfile
+      Writes the notification message to a file or STDOUT/STDERR.
+
+    - network
+      Send the notification to a remote host to handle it somehow.
+
+    - perl
+      Notifications are propagated to plugins written in Perl as well.
+      See collectd-perl(5).
+
+    - python
+      It's possible to implement notification plugins in Python using the
+      python plugin. See collectd-python(5) for details.
+
+  * Value processing can be controlled using the "filter chain" infrastructure
+    and "matches" and "targets". The following plugins are available:
+
+    - match_empty_counter
+      Match counter values which are currently zero.
+
+    - match_hashed
+      Match values using a hash function of the hostname.
+
+    - match_regex
+      Match values by their identifier based on regular expressions.
+
+    - match_timediff
+      Match values with an invalid timestamp.
+
+    - match_value
+      Select values by their data sources' values.
+
+    - target_notification
+      Create and dispatch a notification.
+
+    - target_replace
+      Replace parts of an identifier using regular expressions.
+
+    - target_scale
+      Scale (multiply) values by an arbitrary value.
+
+    - target_set
+      Set (overwrite) entire parts of an identifier.
+
+  * Miscellaneous plugins:
+
+    - aggregation
+      Selects multiple value lists based on patterns or regular expressions
+      and creates new aggregated values lists from those.
+
+    - threshold
+      Checks values against configured thresholds and creates notifications if
+      values are out of bounds. See collectd-threshold(5) for details.
+
+    - uuid
+      Sets the hostname to a unique identifier. This is meant for setups
+      where each client may migrate to another physical host, possibly going
+      through one or more name changes in the process.
+
+  * Performance: Since collectd is running as a daemon it doesn't spend much
+    time starting up again and again. With the exception of the exec plugin no
+    processes are forked. Caching in output plugins, such as the rrdtool and
+    network plugins, makes sure your resources are used efficiently. Also,
+    since collectd is programmed multithreaded it benefits from hyper-threading
+    and multicore processors and makes sure that the daemon isn't idle if only
+    one plugin waits for an IO-operation to complete.
+
+  * Once set up, hardly any maintenance is necessary. Setup is kept as easy
+    as possible and the default values should be okay for most users.
+
+
+Operation
+---------
+
+  * collectd's configuration file can be found at `sysconfdir'/collectd.conf.
+    Run `collectd -h' for a list of built-in defaults. See `collectd.conf(5)'
+    for a list of options and a syntax description.
+
+  * When the `csv' or `rrdtool' plugins are loaded they'll write the values to
+    files. The usual place for these files is beneath `/var/lib/collectd'.
+
+  * When using some of the plugins, collectd needs to run as user root, since
+    only root can do certain things, such as craft ICMP packages needed to ping
+    other hosts. collectd should NOT be installed setuid root since it can be
+    used to overwrite valuable files!
+
+  * Sample scripts to generate graphs reside in `contrib/' in the source
+    package or somewhere near `/usr/share/doc/collectd' in most distributions.
+    Please be aware that those script are meant as a starting point for your
+    own experiments.. Some of them require the `RRDs' Perl module.
+    (`librrds-perl' on Debian) If you have written a more sophisticated
+    solution please share it with us.
+
+  * The RRAs of the automatically created RRD files depend on the `step'
+    and `heartbeat' settings given. If change these settings you may need to
+    re-create the files, losing all data. Please be aware of that when changing
+    the values and read the rrdtool(1) manpage thoroughly.
+
+
+collectd and chkrootkit
+-----------------------
+
+  If you are using the `dns' plugin chkrootkit(1) will report collectd as a
+  packet sniffer ("<iface>: PACKET SNIFFER(/usr/sbin/collectd[<pid>])"). The
+  plugin captures all UDP packets on port 53 to analyze the DNS traffic. In
+  this case, collectd is a legitimate sniffer and the report should be
+  considered to be a false positive. However, you might want to check that
+  this really is collectd and not some other, illegitimate sniffer.
+
+
+Prerequisites
+-------------
+
+  To compile collectd from source you will need:
+
+  * Usual suspects: C compiler, linker, preprocessor, make, ...
+
+  * A POSIX-threads (pthread) implementation.
+    Since gathering some statistics is slow (network connections, slow devices,
+    etc) collectd is parallelized. The POSIX threads interface is being
+    used and should be found in various implementations for hopefully all
+    platforms.
+
+  * aerotools-ng (optional)
+    Used by the `aquaero' plugin. Currently, the `libaquaero5' library, which
+    is used by the `aerotools-ng' toolkit, is not compiled as a shared object
+    nor does it feature an installation routine. Therefore, you need to point
+    collectd's configure script at the source directory of the `aerotools-ng'
+    project.
+    <https://github.com/lynix/aerotools-ng>
+
+  * CoreFoundation.framework and IOKit.framework (optional)

+
+Configuring / Compiling / Installing
+------------------------------------
+
+  To configure, build and install collectd with the default settings, run
+  `./configure && make && make install'.  For detailed, generic instructions
+  see INSTALL. For a complete list of configure options and their description,
+  run `./configure --help'.
+
+  By default, the configure script will check for all build dependencies and
+  disable all plugins whose requirements cannot be fulfilled (any other plugin
+  will be enabled). To enable a plugin, install missing dependencies (see
+  section `Prerequisites' above) and rerun `configure'. If you specify the
+  `--enable-<plugin>' configure option, the script will fail if the depen-
+  dencies for the specified plugin are not met. In that case you can force the
+  plugin to be built using the `--enable-<plugin>=force' configure option.
+  This will most likely fail though unless you're working in a very unusual
+  setup and you really know what you're doing. If you specify the
+  `--disable-<plugin>' configure option, the plugin will not be built. If you
+  specify the `--enable-all-plugins' or `--disable-all-plugins' configure
+  options, all plugins will be enabled or disabled respectively by default.
+  Explicitly enabling or disabling a plugin overwrites the default for the
+  specified plugin. These options are meant for package maintainers and should
+  not be used in everyday situations.
+
+  By default, collectd will be installed into `/opt/collectd'. You can adjust
+  this setting by specifying the `--prefix' configure option - see INSTALL for
+  details. If you pass DESTDIR=<path> to `make install', <path> will be
+  prefixed to all installation directories. This might be useful when creating
+  packages for collectd.
+
+Configuring with libjvm
+-----------------------
+
+  To determine the location of the required files of a Java installation is not
+  an easy task, because the locations vary with your kernel (Linux, SunOS, …)
+  and with your architecture (x86, SPARC, …) and there is no ‘java-config’
+  script we could use. Configuration of the JVM library is therefore a bit
+  tricky.
+
+  The easiest way to use the `--with-java=$JAVA_HOME' option, where
+  `$JAVA_HOME' is usually something like:
+    /usr/lib/jvm/java-1.5.0-sun-1.5.0.14
+
+  The configure script will then use find(1) to look for the following files:
+
+    - jni.h
+    - jni_md.h
+    - libjvm.so
+
+  If found, appropriate CPP-flags and LD-flags are set and the following
+  library checks succeed.
+
+  If this doesn't work for you, you have the possibility to specify CPP-flags,
+  C-flags and LD-flags for the ‘Java’ plugin by hand, using the following three
+  (environment) variables:
+
+    - JAVA_CPPFLAGS
+    - JAVA_CFLAGS
+    - JAVA_LDFLAGS
+
+  For example (shortened for demonstration purposes):
+
+    ./configure JAVA_CPPFLAGS="-I$JAVA_HOME/include -I$JAVA_HOME/include/linux"
+
+  Adding "-ljvm" to the JAVA_LDFLAGS is done automatically, you don't have to
+  do that.
+
+Generating the configure script
+-------------------------------
+
+Collectd ships with a `build.sh' script to generate the `configure'
+script shipped with releases.
+
+To generate the `configure` script, you'll need the following dependencies:
+
+- autoconf
+- automake
+- flex
+- bison
+- libtool
+- libtool-ltdl
+
+The `build.sh' script takes no arguments.
+
+Crosscompiling
+--------------
+
+  To compile correctly collectd needs to be able to initialize static
+  variables to NAN (Not A Number). Some C libraries, especially the GNU
+  libc, have a problem with that.
+
+  Luckily, with GCC it's possible to work around that problem: One can define
+  NAN as being (0.0 / 0.0) and `isnan' as `f != f'. However, to test this
+  ``implementation'' the configure script needs to compile and run a short
+  test program. Obviously running a test program when doing a cross-
+  compilation is, well, challenging.
+
+  If you run into this problem, you can use the `--with-nan-emulation'
+  configure option to force the use of this implementation. We can't promise
+  that the compiled binary actually behaves as it should, but since NANs
+  are likely never passed to the libm you have a good chance to be lucky.
+
+  Likewise, collectd needs to know the layout of doubles in memory, in order
+  to craft uniform network packets over different architectures. For this, it
+  needs to know how to convert doubles into the memory layout used by x86. The
+  configure script tries to figure this out by compiling and running a few
+  small test programs. This is of course not possible when cross-compiling.
+  You can use the `--with-fp-layout' option to tell the configure script which
+  conversion method to assume. Valid arguments are:
+
+    * `nothing'    (12345678 -> 12345678)
+    * `endianflip' (12345678 -> 87654321)
+    * `intswap'    (12345678 -> 56781234)

+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN

+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything

+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.

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

+=head1 NAME
+
+Collectd::Unixsock - Abstraction layer for accessing the functionality by
+collectd's unixsock plugin.
+
+=head1 SYNOPSIS
+
+  use Collectd::Unixsock;
+
+  my $sock = Collectd::Unixsock->new ($path);
+
+  my $value = $sock->getval (%identifier);
+  $sock->putval (%identifier,
+                 time => time (),
+                values => [123, 234, 345]);
+
+  $sock->destroy ();
+
+=head1 DESCRIPTION
+
+collectd's unixsock plugin allows external programs to access the values it has
+collected or received and to submit own values. This Perl-module is simply a
+little abstraction layer over this interface to make it even easier for
+programmers to interact with the daemon.

+=head1 VALUE IDENTIFIERS
+
+The values in the collectd are identified using a five-tuple (host, plugin,
+plugin-instance, type, type-instance) where only plugin instance and type
+instance may be undef. Many functions expect an I<%identifier> hash that has at
+least the members B<host>, B<plugin>, and B<type>, possibly completed by
+B<plugin_instance> and B<type_instance>.
+
+Usually you can pass this hash as follows:
+
+  $self->method (host => $host, plugin => $plugin, type => $type, %other_args);

+# directory of the source distribution.
+#
+# This sample config defines a couple of <MBean /> blocks which query MBeans
+# provided by the JVM itself, i. e. which should be available for all Java
+# processes. The following MBean blocks are defined:

+#   ! classes           ! Number of classes being loaded.                !
+#   ! compilation       ! Time spent by the JVM compiling or optimizing. !
+#   ! garbage_collector ! Number of garbage collections and time spent.  !
+#   ! memory            ! Generic heap/nonheap memory usage.             !

+The files in this directory may be used to perform common tasks that aren't
+exactly `collectd's job. They may or may not require in-depth knowledge of RRD
+files and/or `collectd's inner workings. Use at your own risk.
+
+add_rra.sh
+----------
+  Before version 3.9.0 collectd used to create a different set of RRAs. The
+most detailed of these old RRAs had a one minute resolution. This script can
+be used to add three more RRAs: minimum, maximum and average with a ten second
+resolution and 2200 rows (~6 hours). This will make hourly statistics much more
+interesting. Please note that no sanity- checking whatsoever is performed. You
+can seriously fuck up your RRD files if you don't know what you're doing.
+
+collectd-network.py
+-------------------
+  This Python module by Adrian Perez implements the collectd network protocol
+in pure Python. It currently supports to receive data and notifications from
+collectd.
+
+collectd-unixsock.py
+--------------------
+  This Python module by Clay Loveless provides an interface to collect's
+unixsock plugin.
+
+collectd2html.pl
+----------------
+  This script by Vincent Stehlé will search for RRD files in
+`/var/lib/collectd/' and generate an HTML file and a directory containing
+several PNG files which are graphs of the RRD files found.
+
+collection.cgi
+--------------
+  Sample CGI script that creates graphs on the fly. The Perl modules `RRDs'
+(Debian package `librrds-perl'), `URI:Escape' (package liburi-perl),
+`HTML::Entities' (package libhtml-parser-perl) and a CGI capable web server
+(e.g. apache2 or boa) are needed. Simply install the script to a place where
+the webserver will treat it as a CGI script (/usr/lib/cgi-bin/ by default) and
+visit that page in a browser (http://localhost/cgi-bin/collection.cgi by
+default). Please refer to your webserver's documentation for more details.
+
+  Starting with version 4, collection.cgi requires a small config file, which
+should look something like this:
+
+  datadir: "/var/lib/collectd/rrd/"
+  libdir: "/usr/lib/collectd/"
+
+exec-munin.px
+-------------
+  Script to be used with the exec-plugin (see collectd-exec(5) for details)
+which executes munin plugins, parses the output and translates it to a format
+the exec-plugin understands. The features are limited - changing the munin
+plugins to use the output format understood by the exec-plugin is recommended.
+See the embedded POD documentation for more details:
+ $ perldoc contrib/exec-munin.px
+
+exec-smartctl
+-------------
+  Sample script for the exec plugin. Please refer to the documentation in the
+file - you will have to adapt it to your needs anyway.
+
+extractDS.px
+------------
+  Creates a new RRD-file with only one data-source (DS) of the source-RRD-
+file. That is very handy when you realise that you have bundled up DSes in one
+RRD-file that should have been in multiple RRD-files instead. Is is used by
+`migrate-3-4.px' to split up the cpu-, nfs-, swap-files and possibly others.
+
+fedora/
+-------
+  Init-script and Spec-file that can be used when creating RPM-packages for
+Fedora.
+
+GenericJMX.conf
+---------------
+  Example configuration file for the ‘GenericJMX’ Java plugin. Please read the
+documentation at the beginning of the file for more details.
+
+migrate-3-4.px
+--------------
+  Migration-script to ease the switch from version 3 to version 4. Many
+RRD-files are expected in a different place, some have been changed (DSes have
+been renamed) and others have bee split up into multiple files. This script
+prints a bash-script to STDOUT which should do most of the work for you. You
+may still need to do some things by hand, read `README.migration' for more
+details.
+
+redhat/
+-------
+  Spec-file and affiliated files to build an RedHat RPM package of collectd.
+
+snmp-data.conf
+--------------
+  Sample configuration for the SNMP plugin. This config includes a few standard
+<Data ..> definitions that you can include in your own config using the
+`Include' statement (available since version 4.2.0). The config includes some
+data that is defined in the IF-MIB, e. g. octet or packet counters, UPS-MIB and
+whatever people have send in. If you have some more definitions please send
+them in, so others can profit from it.
+
+solaris-smf
+-----------
+  Manifest file for the Solaris SMF system and detailed information on how to
+register collectd as a service with this system.
+
+collectd.service
+----------------
+  Service file for systemd. Please ship this file as
+  /lib/systemd/system/collectd.service in any linux package of collectd.

+=head1 NAME
+
+Collectd - plugin for filling collectd with stats 
+
+=head1 INSTALLATION
+
+Just copy Collectd.pm into your SpamAssassin Plugin path 
+(e.g /usr/share/perl5/Mail/SpamAssassin/Plugin/) and
+add a loadplugin call into your init.pre file. 
+
+=head1 SYNOPSIS

+
+=head1 USER SETTINGS
+

+
+Where the collectd socket is
+
+=cut 
+
+=item collectd_buffersize [ size ] (default: 256) 
+
+the email plugin uses a fixed buffer, if a line exceeds this size
+it has to be continued in another line. (This is of course handled internally)
+If you have changed this setting please get it in sync with the SA Plugin
+config. 
+
+=cut 
+
+=item collectd_timeout [ sec ] (default: 2) 
+
+if sending data to to collectd takes too long the connection will be aborted. 
+
+=cut
+
+=item collectd_retries [ tries ] (default: 3)
+
+the collectd plugin uses a tread pool, if this is empty the connection fails,
+the SA Plugin then tries to reconnect. With this variable you can indicate how
+often it should try. 
+
+=cut
+
+=head1 DESCRIPTION
+
+This modules uses the email plugin of collectd from Sebastian Harl to
+collect statistical informations in rrd files to create some nice looking
+graphs with rrdtool. They communicate over a unix socket that the collectd
+plugin creates. The generated graphs will be placed in /var/lib/collectd/email

+%description
+collectd is a small daemon which collects system information periodically and
+provides mechanisms to monitor and store the values in a variety of ways. It
+is written in C for performance. Since the daemon doesn't need to startup
+every time it wants to update the values it's very fast and easy on the
+system. Also, the statistics are very fine grained since the files are updated
+every 10 seconds.

+ collection3 - Web frontend for collectd
+=========================================
+http://collectd.org/
+
+About
+-----
+
+  collection3 is a graphing front-end for the RRD files created by and filled
+  with collectd. It is written in Perl and should be run as an CGI-script.
+  Graphs are generated on-the-fly, so no cron job or similar is necessary.
+
+Layout
+------
+
+  The files used by collection3 are organized in a typical UNIX fashion: The
+  configuration resides in etc/, executable scripts are in bin/, supplementary
+  Perl modules are in lib/ and static data for displaying the web page are in
+  share/.
+
+  All files in all subdirectories except bin/ should NOT be executable.
+  Ideally, the webserver should not serve them either. Consider using
+  `.htaccess' files or other means to configure the web server to deny access
+  to these directories.
+
+Dependencies
+------------
+
+  collection3 depends on the following Perl modules not included in the Perl
+  distribution itself:
+
+  * Config::General
+  * Regexp::Common
+  * HTML::Entities
+  * RRDs
+
+Copyright and License
+---------------------
+
+  Copyright (C) 2008  Florian octo Forster <octo at verplant.org>
+
+  collection3 is provided under the terms of the GNU General Public License,
+  version 2 (GPLv2).

+=head1 MODULE LOADING
+
+This script makes use of the various B<Collectd::Graph::Type::*> modules. If a
+file like C<foo.rrd> is encountered it tries to load the
+B<Collectd::Graph::Type::Foo> module and, if that fails, falls back to the
+B<Collectd::Graph::Type> base class.
+
+If you want to create a specialized graph for a certain type, you have to
+create a new module which inherits from the B<Collectd::Graph::Type> base
+class. A description of provided (and used) methods can be found in the inline
+documentation of the B<Collectd::Graph::Type> module.
+
+There are other, more specialized, "abstract" classes that possibly better fit
+your need. Unfortunately they are not yet documented.
+
+=over 4
+
+=item B<Collectd::Graph::Type::GenericStacked>
+
+Specialized class that groups files by their plugin instance and stacks them on
+top of each other. Example types that inherit from this class are
+B<Collectd::Graph::Type::Cpu> and B<Collectd::Graph::Type::Memory>.
+
+=item B<Collectd::Graph::Type::GenericIO>
+
+Specialized class for input/output graphs. This class can only handle files
+with exactly two data sources, input and output. Example types that inherit
+from this class are B<Collectd::Graph::Type::DiskOctets> and
+B<Collectd::Graph::Type::IfOctets>.

+
+=head1 DESCRIPTION
+
+This module serves as base class for more specialized classes realizing
+specific "types".
+
+=head1 MEMBER VARIABLES
+
+As typical in Perl, a Collectd::Graph::Type object is a blessed hash reference.
+Member variables are entries in that hash. Inheriting classes are free to add
+additional entries. To set the member variable B<foo> to B<42>, do:
+
+ $obj->{'foo'} = 42;
+
+The following members control the behavior of Collectd::Graph::Type.
+
+=over 4
+
+=item B<files> (array reference)
+
+List of RRD files. Each file is passed as "ident", i.E<nbsp>e. broken up into
+"hostname", "plugin", "type" and optionally "plugin_instance" and
+"type_instance". Use the B<addFiles> method rather than setting this directly.
+
+=item B<data_sources> (array reference)
+
+List of data sources in the RRD files. If this is not given, the default
+implementation of B<getDataSources> will use B<RRDs::info> to find out which
+data sources are contained in the files.
+
+=item B<ds_names> (array reference)
+
+Names of the data sources as printed in the graph. Should be in the same order
+as the data sources are returned by B<getDataSources>.
+
+=item B<rrd_title> (string)
+
+Title of the RRD graph. The title can contain "{hostname}", "{plugin}" and so
+on which are replaced with their actual value. See the B<getTitle> method
+below.
+
+=item B<rrd_opts> (array reference)
+
+List of options directly passed to B<RRDs::graph>.
+
+=item B<rrd_format> (string)
+
+Format to use with B<GPRINT>. Defaults to C<%5.1lf>.
+
+=item B<rrd_colors> (hash reference)
+
+Mapping of data source names to colors, used when graphing the different data
+sources.  Colors are given in the typical hexadecimal RGB form, but without
+leading "#", e.E<nbsp>g.:
+
+ $obj->{'rrd_colors'} = {foo => 'ff0000', bar => '00ff00'};
+
+=back
+
+=head1 METHODS
+
+The following methods are used by the graphing front end and may be overwritten
+to customize their behavior.

+=head1 DESCRIPTION
+
+This script allows you to use plugins that were written for Munin with
+collectd's C<exec-plugin>. Since the data models of Munin and collectd are
+quite different rewriting the plugins should be preferred over using this
+transition layer. Having more than one "data source" for one "data set" doesn't
+work with this script, for example.

+# Configuration {{{
+
+=head1 CONFIGURATION
+
+This script reads it's configuration from F</etc/exec-munin.conf>. The
+configuration is read using C<Config::General> which understands a Apache-like
+config syntax, so it's very similar to the F<collectd.conf> syntax, too.
+
+Here's a short sample config:
+
+  AddType voltage-in in
+  AddType voltage-out out
+  Interval 300
+  Script /usr/lib/munin/plugins/nut
+
+The options have the following semantic (i.E<nbsp>e. meaning):
+
+=over 4
+
+=item B<AddType> I<to> I<from> [I<from> ...]
+
+collectd uses B<types> to specify how data is structured. In Munin all data is
+structured the same way, so some way of telling collectd how to handle the data
+is needed. This option translates the so called "field names" of Munin to the
+"types" of collectd. If more than one field are of the same type, e.E<nbsp>g.
+the C<nut> plugin above provides C<in> and C<out> which are both voltages, you
+can use a hyphen to add a "type instance" to the type.
+
+For a list of already defined "types" look at the F<types.db> file in
+collectd's shared data directory, e.E<nbsp>g. F</usr/share/collectd/>.
+
+=item B<Interval> I<Seconds>
+
+Sets the interval in which the plugins are executed. This doesn't need to match
+the interval setting of the collectd daemon. Usually, you want to execute the
+Munin plugins much less often, e.E<nbsp>g. every 300 seconds versus every 10
+seconds.
+
+=item B<Script> I<File>
+
+Adds a script to the list of scripts to be executed once per I<Interval>
+seconds.

+This script allows you to use plugins that were written for Nagios with

+consider configuring the threshold using collectd's own facilities instead of
+using this transition layer.

+=head1 CONFIGURATION
+
+This script reads it's configuration from F</etc/exec-nagios.conf>. The
+configuration is read using C<Config::General> which understands a Apache-like
+config syntax, so it's very similar to the F<collectd.conf> syntax, too.
+
+Here's a short sample config:
+
+  NRPEConfig "/etc/nrpe.cfg"
+  Interval 300
+  <Script /usr/lib/nagios/check_tcp>
+    Arguments -H alice -p 22
+    Type delay
+  </Script>
+  <Script /usr/lib/nagios/check_dns>
+    Arguments -H alice
+    Type delay
+  </Script>
+
+The options have the following semantic (i.E<nbsp>e. meaning):
+
+=over 4
+
+=item B<NRPEConfig> I<File>
+
+Read the NRPE config and add the command definitions to an alias table. After
+reading the file you can use the NRPE command name rather than the script's
+filename within B<Script> blocks (see below). If both, the NRPE config and the
+B<Script> block, define arguments they will be merged by concatenating the
+arguments together in the order "NRPE-args Script-args".
+
+Please note that this option is rather dumb. It does not support "command
+argument processing" (i.e. replacing C<$ARG1$> and friends), inclusion of other
+NRPE config files, include directories etc.
+
+=item B<Interval> I<Seconds>
+
+Sets the interval in which the plugins are executed. This doesn't need to match
+the interval setting of the collectd daemon. Usually, you want to execute the
+Nagios plugins much less often, e.E<nbsp>g. every 300 seconds versus every 10
+seconds.
+
+=item E<lt>B<Script> I<File>E<gt>
+
+Adds a script to the list of scripts to be executed once per I<Interval>
+seconds. If the B<NRPEConfig> is given above the B<Script> block, you may use
+the NRPE command name rather than the script's filename. You can use the
+following optional arguments to specify the operation further:
+
+=over 4
+
+=item B<Arguments> I<Arguments>
+
+Pass the arguments I<Arguments> to the script. This is often needed with Nagios
+plugins, because much of the logic is implemented in the plugins, not in the
+daemon. If you need to specify a warning and/or critical range here, please
+consider using collectd's own threshold mechanism, which is by far the more
+elegant solution than this transition layer.
+
+=item B<Type> I<Type>
+
+If the plugin provides "performance data" the performance data is dispatched to
+collectd with this type. If no type is configured the data is ignored. Please
+note that this is limited to types that take exactly one value, such as the
+type C<delay> in the example above. If you need more complex performance data,
+rewrite the plugin as a collectd plugin (or at least port it do run directly
+with the C<exec-plugin>).

+collectd is a small daemon written in C for performance.  It reads various
+system  statistics  and updates  RRD files,  creating  them if neccessary.
+Since the daemon doesn't need to startup every time it wants to update the
+files it's very fast and easy on the system. Also, the statistics are very
+fine grained since the files are updated every 10 seconds.

+
+-- Description
+--------------
+-- This will create a schema to provide collectd with the required permissions
+-- and space for statistic data.
+-- The idea is to store the output of some expensive queries in static tables
+-- and fill these tables with dbms_scheduler jobs as often as necessary.
+-- collectd will then just read from the static tables. This will reduces the
+-- chance that your system will be killed by excessive monitoring queries and
+-- gives the dba control on the interval the information provided to collectd
+-- will be refreshed. You have to create a dbms_scheduler job for each of the
+-- schemas you what to monitor for object-space-usage. See the example below.
+--
+-- Requirements
+---------------
+-- make sure you have: 
+--             write permission in $PWD
+--             you have GID of oracle software owner
+--             set $ORACLE_HOME 
+--             set $ORACLE_SID
+--             DB is up an running in RW mode
+-- execute like this:
+-- sqlplus /nolog @ create_collectd-schema.dll
+
+spool create_collectd-schema.log
+connect / as sysdba
+
+-- Create user, tablespace and permissions

+
+-- Description:
+-- ------------
+--
+-- This is a sample database setup that may be used to write data collected by
+-- collectd to a PostgreSQL database. We're using two tables, 'identifiers'
+-- and 'values' to store the value-list identifier and the actual values
+-- respectively.
+--
+-- The 'values' table is partitioned to improve performance and maintenance.
+-- Please note that additional maintenance scripts are required in order to
+-- keep the setup running -- see the comments below for details.
+--
+-- The function 'collectd_insert' may be used to actually insert values
+-- submitted by collectd into those tables.
+--
+-- Sample configuration:
+-- ---------------------
+--
+-- <Plugin postgresql>
+--     <Writer sqlstore>
+--         Statement "SELECT collectd_insert($1, $2, $3, $4, $5, $6, $7, $8, $9);"
+--     </Writer>
+--     <Database foo>
+--         # ...
+--         Writer sqlstore
+--     </Database>
+-- </Plugin>
+
+CREATE TABLE identifiers (
+    id integer NOT NULL,

+#
+# q: What is this ?
+# a: A specfile for building RPM packages of current collectd releases, for
+#    RHEL/CentOS versions 5, 6 and 7. By default all the plugins which are
+#    buildable based on the libraries available in the distribution + the
+#    EPEL repository, will be built. Plugins depending on external libs will
+#    be packaged in separate RPMs.
+#
+# q: And how can I do that ?
+# a: By following these instructions, using mock:
+#
+# - install and configure mock (https://fedoraproject.org/wiki/Projects/Mock)
+#
+# - enable the EPEL repository (http://dl.fedoraproject.org/pub/epel/) in the
+#   configuration files for your target systems (/etc/mock/*.cfg).
+#
+# - fetch the desired collectd release file from https://collectd.org/files/
+#   and save it in your ~/rpmbuild/SOURCES/ directory (or build your own out of
+#   the git repository: ./build.sh && ./configure && make-dist-bz2)
+#
+# - copy this file in your ~/rpmbuild/SPECS/ directory. Make sure the
+#   "Version:" tag matches the version from the tarball.
+#
+# - build the SRPM first:
+#   mock -r centos-6-x86_64 --buildsrpm --spec ~/rpmbuild/SPECS/collectd.spec \
+#     --sources ~/rpmbuild/SOURCES/
+#
+# - then build the RPMs:
+#   mock -r centos-6-x86_64 --no-clean --rebuild \
+#     /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm
+#
+# - you can also optionally enable/disable plugins which are disabled/enabled
+#   by default:
+#   mock -r centos-6-x86_64 --no-clean --without=java --with=oracle --rebuild \
+#     /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm

+%description
+collectd is a small daemon which collects system information periodically and
+provides mechanisms to monitor and store the values in a variety of ways. It
+is written in C for performance. Since the daemon doesn't need to start up
+every time it wants to update the values it's very fast and easy on the
+system. Also, the statistics are very fine grained since the files are updated
+every 10 seconds by default.

+=head1 NAME
+
+rrd_filter.px - Perform same advanced non-standard operations on an RRD file.
+
+=head1 SYNOPSYS
+
+  rrd_filter.px -i input.rrd -o output.rrd [options]
+
+=head1 DEPENDENCIES
+
+rrd_filter.px requires the RRDTool binary, Perl and the included
+L<Getopt::Long> module.

+=head1 OPTIONS
+
+The following options can be passed on the command line:
+
+=over 4
+
+=item B<--infile> I<file>
+
+=item B<-i> I<file>
+
+Reads from I<file>. If I<file> ends in C<.rrd>, then C<rrdtool dump> is invoked
+to create an XML dump of the RRD file. Otherwise the XML dump is expected
+directly. The special filename C<-> can be used to read from STDIN.
+
+=item B<--outfile> I<file>
+
+=item B<-o> I<file>
+
+Writes output to I<file>. If I<file> ends in C<.rrd>, then C<rrdtool restore>
+is invoked to create a binary RRD file. Otherwise an XML output is written. The
+special filename C<-> can be used to write to STDOUT.
+
+=item B<--map> I<in_ds>:I<out_ds>
+
+=item B<-m> I<in_ds>:I<out_ds>
+
+Writes the datasource I<in_ds> to the output and renames it to I<out_ds>. This
+is useful to extract one DS from an RRD file.
+
+=item B<--step> I<seconds>
+
+=item B<-s> I<seconds>
+
+Changes the step of the output RRD file to be I<seconds>. The new stepsize must
+be a multiple of the old stepsize of the other way around. When increasing the
+stepsize the number of PDPs in each RRA must be dividable by the factor by
+which the stepsize is increased. The length of CDPs and the absolute length of
+RRAs (and thus the data itself) is not altered.
+
+Examples:
+
+  step =  10, rra_steps = 12   =>   step = 60, rra_steps =  2
+  step = 300, rra_steps =  1   =>   step = 10, rra_steps = 30
+
+=item B<--rra> B<RRA>:I<CF>:I<XFF>:I<steps>:I<rows>
+
+=item B<-a> B<RRA>:I<CF>:I<XFF>:I<steps>:I<rows>
+
+Inserts a new RRA in the generated RRD file. This is done B<after> the step has
+been adjusted, take that into account when specifying I<steps> and I<rows>. For
+an explanation of the format please see L<rrdcreate(1)>.
+
+=item B<--scale> I<factor>
+
+Scales the values by the factor I<factor>, i.E<nbsp>e. all values are
+multiplied by I<factor>.
+
+=item B<--shift> I<offset>
+
+Shifts all values by I<offset>, i.E<nbsp>e. I<offset> is added to all values.

+%description
+collectd is a small daemon written in C for performance.  It reads various
+system  statistics  and updates  RRD files,  creating  them if neccessary.
+Since the daemon doesn't need to startup every time it wants to update the
+files it's very fast and easy on the system. Also, the statistics are very
+fine grained since the files are updated every 10 seconds.

+
+snmp-probe-host.px - Find out what information an SNMP device provides.
+
+=head1 SYNOPSIS
+
+  ./snmp-probe-host.px --host switch01.mycompany.com --community ei2Acoum
+
+=head1 DESCRIPTION
+
+The C<snmp-probe-host.px> script can be used to automatically generate SNMP
+configuration snippets for collectd's snmp plugin (see L<collectd-snmp(5)>).
+
+This script parses the collectd configuration and detecs all "data" blocks that
+are defined for the SNMP plugin. It then queries the device specified on the
+command line for all OIDs and registeres which OIDs could be answered correctly
+and which resulted in an error. With that information the script figures out
+which "data" blocks can be used with this hosts and prints an appropriate
+"host" block to standard output.
+
+The script first tries to contact the device via SNMPv2. If after ten seconds
+no working "data" block has been found, it will try to downgrade to SNMPv1.
+This is a bit a hack, but works for now.

+SMF is the way Solaris 10 and later preferably manages services. It is intended
+to replace the old init.d process and provides advances features, such as
+automatic restarting of failing services.
+
+The following blog entry by Piotr Hosowicz describes the process in more
+detail. The original entry can be found at
+<http://phosowicz.jogger.pl/2008/12/21/smf-izing-collectd/>.

+
+      SMF-izing collectd <#>
+
+Wpis na 0. poziomie, wysłany 21 grudnia 2008 o 16:30:49.
+
+My two previous blog entries were about building and running collectd
+<http://collectd.org/> on Sun Solaris 10. After the first one Octo
+contacted me and was so kind as to release a packaged version for x86_64
+<http://collectd.org/download.shtml#solaris>. I have put aside the build
+I rolled on my own and decided to install and run the packaged one on
+the production servers. This blog entry is about SMF-izing the collectd
+daemon.
+
+A few words about the SMF – the Solaris'es Service Management Facility.
+I think it appeared in Solaris 10. From then on the good old |/etc/rcN.d
+|| /etc/init.d| services are called /legacy services/. They still can be
+run, but are not fully supported by SMF. SMF enables you to start and
+stop services in the unified way, can direct you to man pages in case a
+service enters maintenance mode, resolves dependencies between services,
+can store properties of services and so on. A nice feature is that SMF
+will take care of restarting services in case they terminate
+unexpectedly, we will use it at the end to check that things are working
+as they should.
+
+The 3V|L thing about SMF is that each service needs so called SMF
+manifest written in XML and a script or scripts that are executed, when
+the service needs to be stopped or started. It can be one script, which
+should accept respective parameters. Even more 3V|L is the fact that the
+manifest is imported into the SMF database and kept there in SQLite format.
+
+Below you will find collectd manifest and the script. I will post them
+to collectd mailing list in matter of minutes with this blog entry
+serving as a README. Please read all down to the bottom, including the
+remarks.
+
+Manifest (based on the work of Kangurek, thanks!), see the "collectd.xml"

+Script, see the "collectd" file:
+
+ 
+#!/sbin/sh
+ 
+PIDFILE=/opt/collectd/var/run/collectd.pid
+DAEMON=/opt/collectd/sbin/collectd
+ 
+. /lib/svc/share/smf_include.sh
+ 
+case "$1" in
+  start)
+    if [ -f $PIDFILE ] ; then
+      echo "Already running. Stale PID file?"
+      PID=`cat $PIDFILE`
+      echo "$PIDFILE contains $PID"
+      ps -p $PID
+      exit $SMF_EXIT_ERR_FATAL
+    fi
+    $DAEMON
+    if [ $? -ne 0 ] ; then
+      echo $DAEMON faild to start
+      exit $SMF_EXIT_ERR_FATAL
+    fi
+  ;;
+  stop)
+    PID=`cat $PIDFILE 2>/dev/null`
+    kill -15 $PID 2>/dev/null
+    pwait $PID 1> /dev/null 2>/dev/null
+  ;;
+  restart)
+    $0 stop
+    $0 start
+  ;;
+  status)
+    ps -ef | grep collectd | grep -v status | grep -v grep
+  ;;
+  *)
+    echo "Usage: $0 [ start | stop | restart | status ]"
+    exit 1
+  ;;
+esac
+ 
+ 
+exit $SMF_EXIT_OK
+ 
+ 
+
+So you have two files: |collectd| script and |collectd.xml| manifest.
+What do you do with these files?
+
+First – before you begin – make sure that collectd is not running, close
+it down. My script above assumes that you are using the default place
+for PID file. Second: remove / move away collectd's |/etc/rcN.d| and
+|/etc/init.d| stuff, you won't need it from now on, because collectd
+will be SMF-ized. Tada!
+
+Next – install the script in place. It took me a minute or two to figure
+out why Solaris'es |install| tool does not work as expected. It turned
+out that the switches and parameters must be in exactly same order as in
+man page, especially the -c parameter must be first:
+
+|# install -c /lib/svc/method/ -m 755 -u root -g bin collectd|
+
+Now is the moment to test once again that the script is working OK. Try
+running:
+
+|# /lib/svc/method/collectd start
+# /lib/svc/method/collectd stop
+# /lib/svc/method/collectd restart
+|
+
+|pgrep| and |kill| are your friends here, also collectd logs. At last
+stop the collectd service and continue.
+
+Now is the time to /slurp/ attached XML manifest into the SMF database.
+This is done using the |svccfg| tool. Transcript follows:
+
+|# svccfg
+svc:> validate collectd.xml
+svc:> import collectd.xml
+svc:>
+|
+
+It is good to run |validate| command first, especially if you copied and
+pasted the XML manifest from this HTML document opened in your
+browser!!! Second thing worth noting is that |svccfg| starts the service
+immediately upon importing the manifest. It might be not what you want.
+For example it will start collecting data on remote collectd server if
+you use network plugin and it will do it under the hostname, that is not
+right. So be sure to configure collectd prior to running it from SMF.
+
+Now a few words about SMF tools. To see the state of all services issue
+|svcs -a| command. To see state of collectd service issue |svcs
+collectd| command. Quite normal states are enabled and disabled. If you
+see maintenance state then something is wrong. Be sure that you stopped
+all non-SMF collectd processes before you follow the procedure described
+here. To stop collectd the SMF way issue the |svcadm disable
+collectd|command. To start collectd the SMF way issue the |svcadm enable
+collectd|command. Be aware that setting it this way makes the change
+persistent across OS reboots, if you want to enable / disable the
+service only temporarily then add |-t| switch after the |enable| /
+|disable| keywords.
+
+And now is time for a grand finale – seeing if SMF can take care of
+collectd in case it crashes. See PID of collectd either using |pgrep| or
+seeing the contents of the PID file and kill it using |kill|. Then check
+with |svcs collectd| command that SMF has restarted collectd soon
+afterwards. You should see that the service is once again enabled in the
+first column, without your intervention.
+
+Things that could or should be clarified:
+
+    * How hard is it to correct mistakes in manifests? Does svccfg just
+      overwrite entries for specified service FMRI or does it require to
+      delete bad entry (and how to do it?!) and import the correct one?
+    * How does SMF know that a service has crashed / terminated? I
+      attended Sun's trainings and the trainer didn't know how to
+      explain this, we formed a hypothesis that it watches new PIDs
+      after starting a service or something like that. I think it is a
+      bad hypothesis, because SMF can watch PID for the startup script
+      itself but I think not the processes launched inside the script. I
+      have a slight idea that it is done based on so called contracts.

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  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.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+\f
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  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.
+^L
+  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.
+^L
+  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.
+^L
+  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.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+^L
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it
+does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301  USA
+
+Also add information on how to contact you by electronic and paper
+mail.
+
+You should also get your employer (if you work as a programmer) or
+your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James
+Random Hacker.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+\`configure' configures libltdl 2.4.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.

+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+=head1 DESCRIPTION
+
+The C<exec plugin> forks of an executable either to receive values or to
+dispatch notifications to the outside world. The syntax of the configuration is
+explained in L<collectd.conf(5)> but summarized in the above synopsis.
+
+If you want/need better performance or more functionality you should take a
+long look at the C<perl plugin>, L<collectd-perl(5)>.
+
+=head1 EXECUTABLE TYPES
+
+There are currently two types of executables that can be executed by the
+C<exec plugin>:
+

+
+These programs are forked and values that it writes to C<STDOUT> are read back.
+The executable is forked in a fashion similar to L<init>: It is forked once and
+not again until it exits. If it exited, it will be forked again after at most
+I<Interval> seconds. It is perfectly legal for the executable to run for a long
+time and continuously write values to C<STDOUT>.
+
+See L<EXEC DATA FORMAT> below for a description of the output format expected
+from these programs.
+
+B<Warning:> If the executable only writes one value and then exits I will be
+executed every I<Interval> seconds. If I<Interval> is short (the default is 10
+seconds) this may result in serious system load.
+

+
+The program is forked once for each notification that is handled by the daemon.
+The notification is passed to the program on C<STDIN> in a fashion similar to

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fIJava\fR plugin embeds a \fIJava Virtual Machine\fR (\s-1JVM\s0) into \fIcollectd\fR and
+provides a Java interface to part of collectd's \s-1API.\s0 This makes it possible to
+write additions to the daemon in Java.
+.PP
+This plugin is similar in nature to, but shares no code with, the \fIPerl\fR
+plugin by Sebastian Harl, see \fIcollectd\-perl\fR\|(5) for details.
+.SH "CONFIGURATION"
+.IX Header "CONFIGURATION"
+A short outline of this plugin's configuration can be seen in \*(L"\s-1SYNOPSIS\*(R"\s0
+above. For a complete list of all configuration options and their semantics
+please read "Plugin \f(CW\*(C`java\*(C'\fR" in \fIcollectd.conf\fR\|(5).
+.SH "OVERVIEW"
+.IX Header "OVERVIEW"
+When writing additions for collectd in Java, the underlying C base is mostly
+hidden from you. All complex data types are converted to their Java counterparts
+before they're passed to your functions. These Java classes reside in the
+\&\fIorg.collectd.api\fR namespace.
+.PP
+The \fIJava\fR plugin will create one object of each class configured with the
+\&\fBLoadPlugin\fR option. The constructor of this class can then register \*(L"callback
+methods\*(R", i.\ e. methods that will be called by the daemon when
+appropriate.
+.PP
+The available classes are:
+.IP "\fBorg.collectd.api.Collectd\fR" 4
+.IX Item "org.collectd.api.Collectd"
+All \s-1API\s0 functions exported to Java are implemented as static functions of this
+class. See \*(L"\s-1EXPORTED API FUNCTIONS\*(R"\s0 below.

+.SH "REGISTERING CALLBACKS"
+.IX Header "REGISTERING CALLBACKS"
+When starting up, collectd creates an object of each configured class. The
+constructor of this class should then register \*(L"callbacks\*(R" with the daemon,
+using the appropriate static functions in \fBCollectd\fR,
+see \*(L"\s-1EXPORTED API FUNCTIONS\*(R"\s0 above. To register a callback, the object being
+passed to one of the register functions must implement an appropriate
+interface, which are all in the \fBorg.collectd.api\fR namespace.
+.PP
+A constructor may register any number of these callbacks, even none. An object
+without callback methods is never actively called by collectd, but may still
+call the exported \s-1API\s0 functions. One could, for example, start a new thread in
+the constructor and dispatch (submit to the daemon) values asynchronously,
+whenever one is available.
+.PP
+Each callback method is now explained in more detail:
+.SS "config callback"
+.IX Subsection "config callback"
+Interface: \fBorg.collectd.api.CollectdConfigInterface\fR
+.PP
+Signature: \fIint\fR \fBconfig\fR (\fIOConfigItem\fR ci)
+.PP
+This method is passed a \fBOConfigItem\fR object, if both, method and
+configuration, are available. \fBOConfigItem\fR is the root of a tree representing
+the configuration for this plugin. The root itself is the representation of the
+\&\fB<Plugin\ />\fR block, so in next to all cases the children of the
+root are the first interesting objects.
+.PP
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+.PP
+See \*(L"registerConfig\*(R" above.
+.SS "init callback"
+.IX Subsection "init callback"
+Interface: \fBorg.collectd.api.CollectdInitInterface\fR
+.PP
+Signature: \fIint\fR \fBinit\fR ()
+.PP
+This method is called after the configuration has been handled. It is
+supposed to set up the plugin. e.\ g. start threads, open connections, or
+check if can do anything useful at all.
+.PP
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+.PP
+See \*(L"registerInit\*(R" above.
+.SS "read callback"
+.IX Subsection "read callback"
+Interface: \fBorg.collectd.api.CollectdReadInterface\fR
+.PP
+Signature: \fIint\fR \fBread\fR ()
+.PP
+This method is called periodically and is supposed to gather statistics in
+whatever fashion. These statistics are represented as a \fBValueList\fR object and
+sent to the daemon using dispatchValues.
+.PP
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+Currently, returning non-zero does not have any other effects. In particular,
+Java \*(L"read\*(R"\-methods are not suspended for increasing intervals like C
+\&\*(L"read\*(R"\-functions.
+.PP
+See \*(L"registerRead\*(R" above.
+.SS "write callback"
+.IX Subsection "write callback"
+Interface: \fBorg.collectd.api.CollectdWriteInterface\fR
+.PP
+Signature: \fIint\fR \fBwrite\fR (\fIValueList\fR vl)
+.PP
+This method is called whenever a value is dispatched to the daemon. The
+corresponding C \*(L"write\*(R"\-functions are passed a \f(CW\*(C`data_set_t\*(C'\fR, so they can
+decide which values are absolute values (gauge) and which are counter values.
+To get the corresponding \f(CW\*(C`List<DataSource>\*(C'\fR, call the \fBgetDataSource\fR
+method of the \fBValueList\fR object.
+.PP
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+.PP
+See \*(L"registerWrite\*(R" above.
+.SS "flush callback"
+.IX Subsection "flush callback"
+Interface: \fBorg.collectd.api.CollectdFlushInterface\fR
+.PP
+Signature: \fIint\fR \fBflush\fR (\fIint\fR timeout, \fIString\fR identifier)
+.PP
+This method is called when the daemon received a flush command. This can either
+be done using the \f(CW\*(C`USR1\*(C'\fR signal (see \fIcollectd\fR\|(1)) or using the \fIunixsock\fR
+plugin (see \fIcollectd\-unixsock\fR\|(5)).
+.PP
+If \fItimeout\fR is greater than zero, only values older than this number of
+seconds should be flushed. To signal that all values should be flushed
+regardless of age, this argument is set to a negative number.
+.PP
+The \fIidentifier\fR specifies which value should be flushed. If it is not
+possible to flush one specific value, flush all values. To signal that all
+values should be flushed, this argument is set to \fInull\fR.
+.PP
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.

+The GenericJMX plugin reads \fIManaged Beans\fR (MBeans) from an \fIMBeanServer\fR
+using \s-1JMX. JMX\s0 is a generic framework to provide and query various management
+information. The interface is used by Java processes to provide internal
+statistics as well as by the \fIJava Virtual Machine\fR (\s-1JVM\s0) to provide
+information about the memory used, threads and so on.
+.PP
+The configuration of the \fIGenericJMX plugin\fR consists of two blocks: \fIMBean\fR
+blocks that define a mapping of MBean attributes to the XtypesX used by
+\&\fIcollectd\fR, and \fIConnection\fR blocks which define the parameters needed to
+connect to an \fIMBeanServer\fR and what data to collect. The configuration of the
+\&\fI\s-1SNMP\s0 plugin\fR is similar in nature, in case you know it.
+.PP
+\fIMBean blocks\fR
+.IX Subsection "MBean blocks"
+.PP
+\&\fIMBean\fR blocks specify what data is retrieved from \fIMBeans\fR and how that data
+is mapped on the \fIcollectd\fR data types. The block requires one string
+argument, a name. This name is used in the \fIConnection\fR blocks (see below) to
+refer to a specific \fIMBean\fR block. Therefore, the names must be unique.
+.PP
+The following options are recognized within \fIMBean\fR blocks:
+.IP "\fBObjectName\fR \fIpattern\fR" 4
+.IX Item "ObjectName pattern"
+Sets the pattern which is used to retrieve \fIMBeans\fR from the \fIMBeanServer\fR.
+If more than one MBean is returned you should use the \fBInstanceFrom\fR option
+(see below) to make the identifiers unique.

+
+=head1 DESCRIPTION
+
+The I<Java> plugin embeds a I<Java Virtual Machine> (JVM) into I<collectd> and
+provides a Java interface to part of collectd's API. This makes it possible to
+write additions to the daemon in Java.
+
+This plugin is similar in nature to, but shares no code with, the I<Perl>
+plugin by Sebastian Harl, see L<collectd-perl(5)> for details.
+
+=head1 CONFIGURATION
+
+A short outline of this plugin's configuration can be seen in L<"SYNOPSIS">
+above. For a complete list of all configuration options and their semantics
+please read L<collectd.conf(5)/Plugin C<java>>.
+
+=head1 OVERVIEW
+
+When writing additions for collectd in Java, the underlying C base is mostly
+hidden from you. All complex data types are converted to their Java counterparts
+before they're passed to your functions. These Java classes reside in the
+I<org.collectd.api> namespace.
+
+The I<Java> plugin will create one object of each class configured with the
+B<LoadPlugin> option. The constructor of this class can then register "callback
+methods", i.E<nbsp>e. methods that will be called by the daemon when
+appropriate.
+
+The available classes are:
+
+=over 4
+
+=item B<org.collectd.api.Collectd>
+
+All API functions exported to Java are implemented as static functions of this
+class. See L<"EXPORTED API FUNCTIONS"> below.
+

+
+Corresponds to C<oconfig_value_t>, defined in F<src/liboconfig/oconfig.h>.

+

+
+In the remainder of this document, we'll use the short form of these names, for
+example B<ValueList>. In order to be able to use these abbreviated names, you
+need to B<import> the classes.
+
+=head1 EXPORTED API FUNCTIONS
+
+All collectd API functions that are available to Java plugins are implemented
+as I<publicE<nbsp>static> functions of the B<Collectd> class. This makes
+calling these functions pretty straight forward. For example, to send an error
+message to the daemon, you'd do something like this:
+
+  Collectd.logError ("That wasn't chicken!");
+
+The following are the currently exported functions.
+
+=head2 registerConfig

+I<CollectdConfigInterface> object);
+
+Registers the B<config> function of I<object> with the daemon.
+

+
+See L<"config callback"> below.
+
+=head2 registerInit
+
+Signature: I<int> B<registerInit> (I<String> name,

+
+Registers the B<shutdown> function of I<object> with the daemon.
+
+Returns zero upon success and non-zero when an error occurred.
+

+"data sources") associated with the object are ignored, because
+C<plugin_dispatch_values> will automatically lookup the required data set. It
+is therefore absolutely okay to leave this blank.

+Signature: I<void> B<logDebug> (I<String>)
+
+Sends a log message with severity B<DEBUG> to the daemon.
+
+=head1 REGISTERING CALLBACKS
+
+When starting up, collectd creates an object of each configured class. The
+constructor of this class should then register "callbacks" with the daemon,
+using the appropriate static functions in B<Collectd>,
+see L<"EXPORTED API FUNCTIONS"> above. To register a callback, the object being
+passed to one of the register functions must implement an appropriate
+interface, which are all in the B<org.collectd.api> namespace.
+
+A constructor may register any number of these callbacks, even none. An object
+without callback methods is never actively called by collectd, but may still
+call the exported API functions. One could, for example, start a new thread in
+the constructor and dispatch (submit to the daemon) values asynchronously,
+whenever one is available.
+
+Each callback method is now explained in more detail:
+
+=head2 config callback
+
+Interface: B<org.collectd.api.CollectdConfigInterface>
+
+Signature: I<int> B<config> (I<OConfigItem> ci)
+
+This method is passed a B<OConfigItem> object, if both, method and
+configuration, are available. B<OConfigItem> is the root of a tree representing
+the configuration for this plugin. The root itself is the representation of the
+B<E<lt>PluginE<nbsp>/E<gt>> block, so in next to all cases the children of the
+root are the first interesting objects.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+
+See L<"registerConfig"> above.
+
+=head2 init callback
+
+Interface: B<org.collectd.api.CollectdInitInterface>
+
+Signature: I<int> B<init> ()
+
+This method is called after the configuration has been handled. It is
+supposed to set up the plugin. e.E<nbsp>g. start threads, open connections, or
+check if can do anything useful at all.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+
+See L<"registerInit"> above.
+
+=head2 read callback
+
+Interface: B<org.collectd.api.CollectdReadInterface>
+
+Signature: I<int> B<read> ()
+
+This method is called periodically and is supposed to gather statistics in
+whatever fashion. These statistics are represented as a B<ValueList> object and
+sent to the daemon using L<dispatchValues|"dispatchValues">.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+Currently, returning non-zero does not have any other effects. In particular,
+Java "read"-methods are not suspended for increasing intervals like C
+"read"-functions.
+
+See L<"registerRead"> above.
+
+=head2 write callback
+
+Interface: B<org.collectd.api.CollectdWriteInterface>
+
+Signature: I<int> B<write> (I<ValueList> vl)
+
+This method is called whenever a value is dispatched to the daemon. The
+corresponding C "write"-functions are passed a C<data_set_t>, so they can
+decide which values are absolute values (gauge) and which are counter values.
+To get the corresponding C<ListE<lt>DataSourceE<gt>>, call the B<getDataSource>
+method of the B<ValueList> object.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerWrite"> above.
+
+=head2 flush callback
+
+Interface: B<org.collectd.api.CollectdFlushInterface>
+
+Signature: I<int> B<flush> (I<int> timeout, I<String> identifier)
+
+This method is called when the daemon received a flush command. This can either
+be done using the C<USR1> signal (see L<collectd(1)>) or using the I<unixsock>
+plugin (see L<collectd-unixsock(5)>).
+
+If I<timeout> is greater than zero, only values older than this number of
+seconds should be flushed. To signal that all values should be flushed
+regardless of age, this argument is set to a negative number.
+
+The I<identifier> specifies which value should be flushed. If it is not
+possible to flush one specific value, flush all values. To signal that all
+values should be flushed, this argument is set to I<null>.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerFlush"> above.
+
+=head2 shutdown callback
+
+Interface: B<org.collectd.api.CollectdShutdownInterface>
+
+Signature: I<int> B<shutdown> ()
+
+This method is called when the daemon is shutting down. You should not rely on
+the destructor to clean up behind the object but use this function instead.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerShutdown"> above.
+
+=head2 log callback
+
+Interface: B<org.collectd.api.CollectdLogInterface>
+
+Signature: I<void> B<log> (I<int> severity, I<String> message)
+
+This callback can be used to receive log messages from the daemon.
+
+The argument I<severity> is one of:

+=head2 notification callback
+
+Interface: B<org.collectd.api.CollectdNotificationInterface>
+
+Signature: I<int> B<notification> (I<Notification> n)
+
+This callback can be used to receive notifications from the daemon.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerNotification"> above.
+
+=head2 match callback
+
+The match (and target, see L<"target callback"> below) callbacks work a bit
+different from the other callbacks above: You don't register a match callback
+with the daemon directly, but you register a function which, when called,
+creates an appropriate object. The object creating the "match" objects is
+called "match factory".

+=head1 EXAMPLE
+
+This short example demonstrates how to register a read callback with the
+daemon:
+
+  import org.collectd.api.Collectd;
+  import org.collectd.api.ValueList;
+  
+  import org.collectd.api.CollectdReadInterface;
+  
+  public class Foobar implements CollectdReadInterface
+  {
+    public Foobar ()
+    {
+      Collectd.registerRead ("Foobar", this);
+    }
+    
+    public int read ()
+    {
+      ValueList vl;
+      
+      /* Do something... */
+      
+      Collectd.dispatchValues (vl);
+    }
+  }
+
+=head1 PLUGINS
+
+The following plugins are implemented in I<Java>. Both, the B<LoadPlugin>
+option and the B<Plugin> block must be inside the
+B<E<lt>PluginE<nbsp>javaE<gt>> block (see above).
+
+=head2 GenericJMX plugin
+
+The GenericJMX plugin reads I<Managed Beans> (MBeans) from an I<MBeanServer>
+using JMX. JMX is a generic framework to provide and query various management
+information. The interface is used by Java processes to provide internal
+statistics as well as by the I<Java Virtual Machine> (JVM) to provide
+information about the memory used, threads and so on. 
+
+The configuration of the I<GenericJMX plugin> consists of two blocks: I<MBean>
+blocks that define a mapping of MBean attributes to the “types” used by
+I<collectd>, and I<Connection> blocks which define the parameters needed to
+connect to an I<MBeanServer> and what data to collect. The configuration of the
+I<SNMP plugin> is similar in nature, in case you know it.
+
+=head3   MBean blocks
+
+I<MBean> blocks specify what data is retrieved from I<MBeans> and how that data
+is mapped on the I<collectd> data types. The block requires one string
+argument, a name. This name is used in the I<Connection> blocks (see below) to
+refer to a specific I<MBean> block. Therefore, the names must be unique.
+
+The following options are recognized within I<MBean> blocks: 
+
+=over 4
+
+=item B<ObjectName> I<pattern>
+
+Sets the pattern which is used to retrieve I<MBeans> from the I<MBeanServer>.
+If more than one MBean is returned you should use the B<InstanceFrom> option
+(see below) to make the identifiers unique.
+
+See also:
+L<http://java.sun.com/javase/6/docs/api/javax/management/ObjectName.html>
+
+=item B<InstancePrefix> I<prefix>
+
+Prefixes the generated I<plugin instance> with I<prefix>. I<(optional)>
+
+=item B<InstanceFrom> I<property>
+
+The I<object names> used by JMX to identify I<MBeans> include so called
+I<“properties”> which are basically key-value-pairs. If the given object name
+is not unique and multiple MBeans are returned, the values of those properties
+usually differ. You can use this option to build the I<plugin instance> from
+the appropriate property values. This option is optional and may be repeated to
+generate the I<plugin instance> from multiple property values. 
+
+=item B<E<lt>value /E<gt>> blocks
+
+The I<value> blocks map one or more attributes of an I<MBean> to a value list
+in I<collectd>. There must be at least one Value block within each I<MBean>
+block.
+
+=over 4
+
+=item B<Type> type
+
+Sets the data set used within I<collectd> to handle the values of the I<MBean>
+attribute.
+
+=item B<InstancePrefix> I<prefix>
+
+Works like the option of the same name directly beneath the I<MBean> block, but
+sets the type instance instead. I<(optional)>
+
+=item B<InstanceFrom> I<prefix>
+
+Works like the option of the same name directly beneath the I<MBean> block, but
+sets the type instance instead. I<(optional)>
+
+=item B<Table> B<true>|B<false>
+
+Set this to true if the returned attribute is a I<composite type>. If set to
+true, the keys within the I<composite type> is appended to the
+I<type instance>.
+
+=item B<Attribute> I<path>
+
+Sets the name of the attribute from which to read the value. You can access the
+keys of composite types by using a dot to concatenate the key name to the
+attribute name. For example: “attrib0.key42”. If B<Table> is set to B<true>
+I<path> must point to a I<composite type>, otherwise it must point to a numeric
+type.

+
+=head3 Connection blocks
+
+Connection blocks specify I<how> to connect to an I<MBeanServer> and what data
+to retrieve. The following configuration options are available:
+
+=over 4
+
+=item B<Host> I<name>
+
+Host name used when dispatching the values to I<collectd>. The option sets this
+field only, it is I<not> used to connect to anything and doesn't need to be a
+real, resolvable name.
+
+=item B<ServiceURL> I<URL>
+
+Specifies how the I<MBeanServer> can be reached. Any string accepted by the
+I<JMXServiceURL> is valid.
+
+See also:
+L<http://java.sun.com/javase/6/docs/api/javax/management/remote/JMXServiceURL.html>
+
+=item B<User> I<name>
+
+Use I<name> to authenticate to the server. If not configured, “monitorRole”
+will be used.
+
+=item B<Password> I<password>
+
+Use I<password> to authenticate to the server. If not given, unauthenticated
+access is used.
+
+=item B<InstancePrefix> I<prefix>
+
+Prefixes the generated I<plugin instance> with I<prefix>. If a second
+I<InstancePrefix> is specified in a referenced I<MBean> block, the prefix
+specified in the I<Connection> block will appear at the beginning of the
+I<plugin instance>, the prefix specified in the I<MBean> block will be appended
+to it.
+
+=item B<Collect> I<mbean_block_name>
+
+Configures which of the I<MBean> blocks to use with this connection. May be
+repeated to collect multiple I<MBeans> from this server.

+.SH "NAME"
+collectd\-nagios \- Nagios plugin for querying collectd
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+collectd-nagios \fB\-s\fR \fIsocket\fR \fB\-n\fR \fIvalue_spec\fR \fB\-H\fR \fIhostname\fR \fI[options]\fR
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This small program is the glue between collectd and nagios. collectd collects
+various performance statistics which it provides via the \f(CW\*(C`unixsock plugin\*(C'\fR,
+see \fIcollectd\-unixsock\fR\|(5). This program is called by Nagios, connects to the
+\&\s-1UNIX\s0 socket and reads the values from collectd. It then returns \fB\s-1OKAY\s0\fR,
+\&\fB\s-1WARNING\s0\fR or \fB\s-1CRITICAL\s0\fR depending on the values and the ranges provided by
+Nagios.
+.SH "ARGUMENTS AND OPTIONS"
+.IX Header "ARGUMENTS AND OPTIONS"
+The following arguments and options are required and understood by
+collectd-nagios. The order of the arguments generally doesn't matter, as long
+as no argument is passed more than once.
+.IP "\fB\-s\fR \fIsocket\fR" 4
+.IX Item "-s socket"
+Path of the \s-1UNIX\s0 socket opened by collectd's \f(CW\*(C`unixsock plugin\*(C'\fR.
+.IP "\fB\-n\fR \fIvalue_spec\fR" 4
+.IX Item "-n value_spec"
+The value to read from collectd. The argument is in the form
+\&\f(CW\*(C`plugin[\-instance]/type[\-instance]\*(C'\fR.
+.IP "\fB\-H\fR \fIhostname\fR" 4
+.IX Item "-H hostname"
+Hostname to query the values for.
+.IP "\fB\-d\fR \fIdata_source\fR" 4
+.IX Item "-d data_source"
+Each \fIvalue_spec\fR may be made of multiple \*(L"data sources\*(R". With this option you
+can select one or more data sources. To select multiple data sources simply
+specify this option again. If multiple data sources are examined they are
+handled according to the consolidation function given with the \fB\-g\fR option.
+.IP "\fB\-g\fR \fBnone\fR\fI|\fR\fBaverage\fR\fI|\fR\fBsum\fR" 4
+.IX Item "-g none|average|sum"
+When multiple data sources are selected from a value spec, they can be handled
+differently depending on this option. The values of the following meaning:
+.RS 4
+.IP "\fBnone\fR" 4
+.IX Item "none"
+No consolidation if done and the warning and critical regions are applied to
+each value independently.
+.IP "\fBaverage\fR" 4
+.IX Item "average"
+The warning and critical ranges are applied to the average of all values.
+.IP "\fBsum\fR" 4
+.IX Item "sum"
+The warning and critical ranges are applied to the sum of all values.
+.IP "\fBpercentage\fR" 4
+.IX Item "percentage"
+The warning and critical ranges are applied to the ratio (in percent) of the
+first value and the sum of all values. A warning is returned if the first
+value is not defined or if all values sum up to zero.
+.RE
+.RS 4
+.RE
+.IP "\fB\-c\fR \fIrange\fR" 4
+.IX Item "-c range"
+.PD 0
+.IP "\fB\-w\fR \fIrange\fR" 4
+.IX Item "-w range"
+.PD
+Set the critical (\fB\-c\fR) and warning (\fB\-w\fR) ranges. These options mostly
+follow the normal syntax of Nagios plugins. The general format is
+"\fImin\fR\fB:\fR\fImax\fR". If a value is smaller than \fImin\fR or bigger than \fImax\fR, a
+\&\fIwarning\fR or \fIcritical\fR status is returned, otherwise the status is
+\&\fIsuccess\fR.
+.Sp
+The tilde sign (\fB~\fR) can be used to explicitly specify infinity. If \fB~\fR is
+used as a \fImin\fR value, negative infinity is used. In case of \fImax\fR, it is
+interpreted as positive infinity.
+.Sp
+If the first character of the \fIrange\fR is the at\ sign (\fB@\fR), the meaning
+of the range will be inverted. I.\ e. all values \fIwithin\fR the range will
+yield a \fIwarning\fR or \fIcritical\fR status, while all values \fIoutside\fR the range
+will result in a \fIsuccess\fR status.
+.Sp
+\&\fImin\fR (and the colon) may be omitted,
+\&\fImin\fR is then assumed to be zero. If \fImax\fR (but not the trailing colon) is
+omitted, \fImax\fR is assumed to be positive infinity.
+.IP "\fB\-m\fR" 4
+.IX Item "-m"
+If this option is given, \*(L"Not a Number\*(R" (NaN) is treated as \fIcritical\fR. By
+default, the \fInone\fR consolidation reports NaNs as \fIwarning\fR. Other
+consolidations simply ignore NaN values.
+.SH "RETURN VALUE"
+.IX Header "RETURN VALUE"
+As usual for Nagios plugins, this program writes a short, one line status
+message to \s-1STDOUT\s0 and signals success or failure with it's return value. It
+exits with a return value of \fB0\fR for \fIsuccess\fR, \fB1\fR for \fIwarning\fR and \fB2\fR
+for \fIcritical\fR. If the values are not available or some other error occurred,
+it returns \fB3\fR for \fIunknown\fR.
+.SH "SEE ALSO"

+=head1 NAME
+
+collectd-nagios - Nagios plugin for querying collectd
+
+=head1 SYNOPSIS
+
+collectd-nagios B<-s> I<socket> B<-n> I<value_spec> B<-H> I<hostname> I<[options]>
+
+=head1 DESCRIPTION
+
+This small program is the glue between collectd and nagios. collectd collects
+various performance statistics which it provides via the C<unixsock plugin>,
+see L<collectd-unixsock(5)>. This program is called by Nagios, connects to the
+UNIX socket and reads the values from collectd. It then returns B<OKAY>,
+B<WARNING> or B<CRITICAL> depending on the values and the ranges provided by
+Nagios.
+
+=head1 ARGUMENTS AND OPTIONS
+
+The following arguments and options are required and understood by
+collectd-nagios. The order of the arguments generally doesn't matter, as long
+as no argument is passed more than once.
+
+=over 4
+
+=item B<-s> I<socket>
+
+Path of the UNIX socket opened by collectd's C<unixsock plugin>.
+
+=item B<-n> I<value_spec>
+
+The value to read from collectd. The argument is in the form
+C<plugin[-instance]/type[-instance]>.
+
+=item B<-H> I<hostname>
+
+Hostname to query the values for.
+
+=item B<-d> I<data_source>
+
+Each I<value_spec> may be made of multiple "data sources". With this option you
+can select one or more data sources. To select multiple data sources simply
+specify this option again. If multiple data sources are examined they are
+handled according to the consolidation function given with the B<-g> option.
+
+=item B<-g> B<none>I<|>B<average>I<|>B<sum>
+
+When multiple data sources are selected from a value spec, they can be handled
+differently depending on this option. The values of the following meaning:
+
+=over 4
+
+=item B<none>
+
+No consolidation if done and the warning and critical regions are applied to
+each value independently.
+
+=item B<average>
+
+The warning and critical ranges are applied to the average of all values.
+
+=item B<sum>
+
+The warning and critical ranges are applied to the sum of all values.
+
+=item B<percentage>
+
+The warning and critical ranges are applied to the ratio (in percent) of the
+first value and the sum of all values. A warning is returned if the first
+value is not defined or if all values sum up to zero.
+
+=back
+
+=item B<-c> I<range>
+
+=item B<-w> I<range>
+
+Set the critical (B<-c>) and warning (B<-w>) ranges. These options mostly
+follow the normal syntax of Nagios plugins. The general format is
+"I<min>B<:>I<max>". If a value is smaller than I<min> or bigger than I<max>, a
+I<warning> or I<critical> status is returned, otherwise the status is
+I<success>.
+
+The tilde sign (B<~>) can be used to explicitly specify infinity. If B<~> is
+used as a I<min> value, negative infinity is used. In case of I<max>, it is
+interpreted as positive infinity.
+
+If the first character of the I<range> is the atE<nbsp>sign (B<@>), the meaning
+of the range will be inverted. I.E<nbsp>e. all values I<within> the range will
+yield a I<warning> or I<critical> status, while all values I<outside> the range
+will result in a I<success> status.
+
+I<min> (and the colon) may be omitted,
+I<min> is then assumed to be zero. If I<max> (but not the trailing colon) is
+omitted, I<max> is assumed to be positive infinity.
+
+=item B<-m>
+
+If this option is given, "Not a Number" (NaN) is treated as I<critical>. By
+default, the I<none> consolidation reports NaNs as I<warning>. Other
+consolidations simply ignore NaN values.
+
+=back
+
+=head1 RETURN VALUE
+
+As usual for Nagios plugins, this program writes a short, one line status
+message to STDOUT and signals success or failure with it's return value. It
+exits with a return value of B<0> for I<success>, B<1> for I<warning> and B<2>
+for I<critical>. If the values are not available or some other error occurred,
+it returns B<3> for I<unknown>.

+.SH "WRITING YOUR OWN PLUGINS"
+.IX Header "WRITING YOUR OWN PLUGINS"
+Writing your own plugins is quite simple. collectd manages plugins by means of
+\&\fBdispatch functions\fR which call the appropriate \fBcallback functions\fR
+registered by the plugins. Any plugin basically consists of the implementation
+of these callback functions and initializing code which registers the
+functions with collectd. See the section \*(L"\s-1EXAMPLES\*(R"\s0 below for a really basic
+example. The following types of \fBcallback functions\fR are known to collectd
+(all of them are optional):
+.IP "configuration functions" 4
+.IX Item "configuration functions"
+This type of functions is called during configuration if an appropriate
+\&\fBPlugin\fR block has been encountered. It is called once for each \fBPlugin\fR
+block which matches the name of the callback as provided with the
+\&\fBplugin_register\fR method \- see below.
+.IP "init functions" 4
+.IX Item "init functions"
+This type of functions is called once after loading the module and before any
+calls to the read and write functions. It should be used to initialize the
+internal state of the plugin (e.\ g. open sockets, ...). If the return
+value evaluates to \fBfalse\fR, the plugin will be disabled.
+.IP "read functions" 4
+.IX Item "read functions"
+This type of function is used to collect the actual data. It is called once
+per interval (see the \fBInterval\fR configuration option of collectd). Usually
+it will call \fBplugin_dispatch_values\fR to dispatch the values to collectd
+which will pass them on to all registered \fBwrite functions\fR. If the return
+value evaluates to \fBfalse\fR the plugin will be skipped for an increasing
+amount of time until it returns \fBtrue\fR again.
+.IP "write functions" 4
+.IX Item "write functions"
+This type of function is used to write the dispatched values. It is called
+once for each call to \fBplugin_dispatch_values\fR.
+.IP "flush functions" 4
+.IX Item "flush functions"
+This type of function is used to flush internal caches of plugins. It is
+usually triggered by the user only. Any plugin which caches data before
+writing it to disk should provide this kind of callback function.
+.IP "log functions" 4
+.IX Item "log functions"
+This type of function is used to pass messages of plugins or the daemon itself
+to the user.
+.IP "notification function" 4
+.IX Item "notification function"
+This type of function is used to act upon notifications. In general, a
+notification is a status message that may be associated with a data instance.
+Usually, a notification is generated by the daemon if a configured threshold
+has been exceeded (see the section \*(L"\s-1THRESHOLD CONFIGURATION\*(R"\s0 in
+\&\fIcollectd.conf\fR\|(5) for more details), but any plugin may dispatch
+notifications as well.
+.IP "shutdown functions" 4
+.IX Item "shutdown functions"
+This type of function is called once before the daemon shuts down. It should
+be used to clean up the plugin (e.g. close sockets, ...).
+.PP
+Any function (except log functions) may set the \fB$@\fR variable to describe
+errors in more detail. The message will be passed on to the user using
+collectd's logging mechanism.
+.PP
+See the documentation of the \fBplugin_register\fR method in the section
+\&\*(L"\s-1METHODS\*(R"\s0 below for the number and types of arguments passed to each
+\&\fBcallback function\fR. This section also explains how to register \fBcallback
+functions\fR with collectd.
+.PP
+To enable a plugin, copy it to a place where Perl can find it (i.\ e. a
+directory listed in the \fB\f(CB@INC\fB\fR array) just as any other Perl plugin and add
+an appropriate \fBLoadPlugin\fR option to the configuration file. After
+restarting collectd you're done.
+.SH "DATA TYPES"
+.IX Header "DATA TYPES"
+The following complex types are used to pass values between the Perl plugin
+and collectd:
+.IP "Config-Item" 4
+.IX Item "Config-Item"
+A config-item is one structure which keeps the information provided in the
+configuration file. The array of children keeps one entry for each
+configuration option. Each such entry is another config-item structure, which
+may nest further if nested blocks are used.
+.Sp

+.Ve
+.IP "Data-Set" 4
+.IX Item "Data-Set"
+A data-set is a list of one or more data-sources. Each data-source defines a
+name, type, min\- and max-value and the data-set wraps them up into one
+structure. The general layout looks like this:
+.Sp
+.Vb 6
+\&  [{

+\&    max  => value || undef
+\&  }, ...]
+.Ve
+.IP "Value-List" 4
+.IX Item "Value-List"
+A value-list is one structure which features an array of values and fields to
+identify the values, i.\ e. time and host, plugin name and
+plugin-instance as well as a type and type-instance. Since the \*(L"type\*(R" is not
+included in the value-list but is passed as an extra argument, the general
+layout looks like this:
+.Sp
+.Vb 10

+.Ve
+.IP "Notification" 4
+.IX Item "Notification"
+A notification is one structure defining the severity, time and message of the
+status message as well as an identification of a data instance. Also, it
+includes an optional list of user-defined meta information represented as
+(name, value) pairs:

+is the value passed as \fIname\fR here and has nothing to do with the \fItype\fR
+argument which simply tells \fBplugin_register\fR what is being registered.)
+.Sp
+The last argument, \fIdata\fR, is either a function name or an array-reference.
+If \fItype\fR is \fB\s-1TYPE_DATASET\s0\fR, then the \fIdata\fR argument must be an
+array-reference which points to an array of hashes. Each hash describes one

+there is a large number of predefined data-sets available in the \fBtypes.db\fR
+file which are automatically registered with collectd \- see \fItypes.db\fR\|(5) for
+a description of the format of this file.
+.Sp
+\&\fBNote\fR: Using \fBplugin_register\fR to register a data-set is deprecated. Add
+the new type to a custom \fItypes.db\fR\|(5) file instead. This functionality might
+be removed in a future version of collectd.
+.Sp
+If the \fItype\fR argument is any of the other types (\fB\s-1TYPE_INIT\s0\fR, \fB\s-1TYPE_READ\s0\fR,
+\&...) then \fIdata\fR is expected to be a function name. If the name is not
+prefixed with the plugin's package name collectd will add it automatically.
+The interface slightly differs from the C interface (which expects a function
+pointer instead) because Perl does not support to share references to
+subroutines between threads.

+collectd is heavily multi-threaded. Each collectd thread accessing the perl
+plugin will be mapped to a Perl interpreter thread (see \fIthreads\fR\|(3perl)).
+Any such thread will be created and destroyed transparently and on-the-fly.
+.Sp
+Hence, any plugin has to be thread-safe if it provides several entry points
+from collectd (i.\ e. if it registers more than one callback or if a
+registered callback may be called more than once in parallel). Please note
+that no data is shared between threads by default. You have to use the
+\&\fBthreads::shared\fR module to do so.
+.IP "\(bu" 4
+Each function name registered with collectd has to be available before the

+\&\f(CW\*(C`*foo = \e&bar; plugin_register (TYPE_READ, "plugin", "foo");\*(C'\fR most likely
+will not work. This is due to the fact that the symbol table is not shared

+Each plugin is usually only loaded once and kept in memory for performance

+The perl plugin exports the internal \s-1API\s0 of collectd which is considered

+=head1 NAME
+
+collectd-perl - Documentation of collectd's C<perl plugin>
+
+=head1 SYNOPSIS
+
+  LoadPlugin perl
+  # ...
+  <Plugin perl>
+    IncludeDir "/path/to/perl/plugins"
+    BaseName "Collectd::Plugins"
+    EnableDebugger ""
+    LoadPlugin "FooBar"
+
+    <Plugin FooBar>
+      Foo "Bar"
+    </Plugin>
+  </Plugin>
+
+=head1 DESCRIPTION
+
+The C<perl plugin> embeds a Perl-interpreter into collectd and provides an
+interface to collectd's plugin system. This makes it possible to write plugins
+for collectd in Perl. This is a lot more efficient than executing a
+Perl-script every time you want to read a value with the C<exec plugin> (see
+L<collectd-exec(5)>) and provides a lot more functionality, too.
+
+=head1 CONFIGURATION
+
+=over 4
+
+=item B<LoadPlugin> I<Plugin>
+
+Loads the Perl plugin I<Plugin>. This does basically the same as B<use> would
+do in a Perl program. As a side effect, the first occurrence of this option
+causes the Perl-interpreter to be initialized.
+
+=item B<BaseName> I<Name>
+
+Prepends I<Name>B<::> to all plugin names loaded after this option. This is
+provided for convenience to keep plugin names short. All Perl-based plugins
+provided with the I<collectd> distributions reside in the C<Collectd::Plugins>
+namespace.
+
+=item E<lt>B<Plugin> I<Name>E<gt> block
+
+This block may be used to pass on configuration settings to a Perl plugin. The
+configuration is converted into a config-item data type which is passed to the
+registered configuration callback. See below for details about the config-item
+data type and how to register callbacks.
+
+The I<name> identifies the callback. It is used literally and independent of
+the B<BaseName> setting.
+
+=item B<EnableDebugger> I<Package>[=I<option>,...]
+
+Run collectd under the control of the Perl source debugger. If I<Package> is
+not the empty string, control is passed to the debugging, profiling, or
+tracing module installed as Devel::I<Package>. A comma-separated list of
+options may be specified after the "=" character. Please note that you may not
+leave out the I<Package> option even if you specify B<"">. This is the same as
+using the B<-d:Package> command line option.
+
+See L<perldebug> for detailed documentation about debugging Perl.
+
+This option does not prevent collectd from daemonizing, so you should start
+collectd with the B<-f> command line option. Else you will not be able to use
+the command line driven interface of the debugger.
+
+=item B<IncludeDir> I<Dir>
+
+Adds I<Dir> to the B<@INC> array. This is the same as using the B<-IDir>
+command line option or B<use lib Dir> in the source code. Please note that it
+only has effect on plugins loaded after this option.
+
+=back
+
+=head1 WRITING YOUR OWN PLUGINS
+
+Writing your own plugins is quite simple. collectd manages plugins by means of
+B<dispatch functions> which call the appropriate B<callback functions>
+registered by the plugins. Any plugin basically consists of the implementation
+of these callback functions and initializing code which registers the
+functions with collectd. See the section "EXAMPLES" below for a really basic
+example. The following types of B<callback functions> are known to collectd
+(all of them are optional):
+
+=over 4
+
+=item configuration functions
+
+This type of functions is called during configuration if an appropriate
+B<Plugin> block has been encountered. It is called once for each B<Plugin>
+block which matches the name of the callback as provided with the
+B<plugin_register> method - see below.
+
+=item init functions
+
+This type of functions is called once after loading the module and before any
+calls to the read and write functions. It should be used to initialize the
+internal state of the plugin (e.E<nbsp>g. open sockets, ...). If the return
+value evaluates to B<false>, the plugin will be disabled.
+
+=item read functions
+
+This type of function is used to collect the actual data. It is called once
+per interval (see the B<Interval> configuration option of collectd). Usually
+it will call B<plugin_dispatch_values> to dispatch the values to collectd
+which will pass them on to all registered B<write functions>. If the return
+value evaluates to B<false> the plugin will be skipped for an increasing
+amount of time until it returns B<true> again.
+
+=item write functions
+
+This type of function is used to write the dispatched values. It is called
+once for each call to B<plugin_dispatch_values>.
+
+=item flush functions
+
+This type of function is used to flush internal caches of plugins. It is
+usually triggered by the user only. Any plugin which caches data before
+writing it to disk should provide this kind of callback function.
+
+=item log functions
+
+This type of function is used to pass messages of plugins or the daemon itself
+to the user.
+
+=item notification function
+
+This type of function is used to act upon notifications. In general, a
+notification is a status message that may be associated with a data instance.
+Usually, a notification is generated by the daemon if a configured threshold
+has been exceeded (see the section "THRESHOLD CONFIGURATION" in
+L<collectd.conf(5)> for more details), but any plugin may dispatch
+notifications as well.
+
+=item shutdown functions
+
+This type of function is called once before the daemon shuts down. It should
+be used to clean up the plugin (e.g. close sockets, ...).
+
+=back
+
+Any function (except log functions) may set the B<$@> variable to describe
+errors in more detail. The message will be passed on to the user using
+collectd's logging mechanism.
+
+See the documentation of the B<plugin_register> method in the section
+"METHODS" below for the number and types of arguments passed to each
+B<callback function>. This section also explains how to register B<callback
+functions> with collectd.
+
+To enable a plugin, copy it to a place where Perl can find it (i.E<nbsp>e. a
+directory listed in the B<@INC> array) just as any other Perl plugin and add
+an appropriate B<LoadPlugin> option to the configuration file. After
+restarting collectd you're done.
+
+=head1 DATA TYPES
+
+The following complex types are used to pass values between the Perl plugin
+and collectd:
+
+=over 4
+
+=item Config-Item
+
+A config-item is one structure which keeps the information provided in the
+configuration file. The array of children keeps one entry for each
+configuration option. Each such entry is another config-item structure, which
+may nest further if nested blocks are used.
+
+  {
+    key      => key,
+    values   => [ val1, val2, ... ],
+    children => [ { ... }, { ... }, ... ]
+  }
+
+=item Data-Set
+
+A data-set is a list of one or more data-sources. Each data-source defines a
+name, type, min- and max-value and the data-set wraps them up into one
+structure. The general layout looks like this:
+
+  [{
+    name => 'data_source_name',
+    type => DS_TYPE_COUNTER || DS_TYPE_GAUGE || DS_TYPE_DERIVE || DS_TYPE_ABSOLUTE,
+    min  => value || undef,
+    max  => value || undef
+  }, ...]
+
+=item Value-List
+
+A value-list is one structure which features an array of values and fields to
+identify the values, i.E<nbsp>e. time and host, plugin name and
+plugin-instance as well as a type and type-instance. Since the "type" is not
+included in the value-list but is passed as an extra argument, the general
+layout looks like this:
+
+  {
+    values => [123, 0.5],
+    time   => time (),
+    interval => plugin_get_interval (),
+    host   => $hostname_g,
+    plugin => 'myplugin',
+    type   => 'myplugin',
+    plugin_instance => '',
+    type_instance   => ''
+  }
+
+=item Notification
+
+A notification is one structure defining the severity, time and message of the
+status message as well as an identification of a data instance. Also, it
+includes an optional list of user-defined meta information represented as
+(name, value) pairs:
+
+  {
+    severity => NOTIF_FAILURE || NOTIF_WARNING || NOTIF_OKAY,
+    time     => time (),
+    message  => 'status message',
+    host     => $hostname_g,
+    plugin   => 'myplugin',
+    type     => 'mytype',
+    plugin_instance => '',
+    type_instance   => '',
+    meta     => [ { name => <name>, value => <value> }, ... ]
+  }
+
+=item Match-Proc
+
+A match-proc is one structure storing the callbacks of a "match" of the filter
+chain infrastructure. The general layout looks like this:
+
+  {
+    create  => 'my_create',
+    destroy => 'my_destroy',
+    match   => 'my_match'
+  }
+
+=item Target-Proc
+
+A target-proc is one structure storing the callbacks of a "target" of the
+filter chain infrastructure. The general layout looks like this:
+
+  {
+    create  => 'my_create',
+    destroy => 'my_destroy',
+    invoke  => 'my_invoke'
+  }
+
+=back
+
+=head1 METHODS
+
+The following functions provide the C-interface to Perl-modules. They are
+exported by the ":plugin" export tag (see the section "EXPORTS" below).
+
+=over 4
+
+=item B<plugin_register> (I<type>, I<name>, I<data>)
+
+Registers a callback-function or data-set.
+
+I<type> can be one of:
+
+=over 4
+
+=item TYPE_CONFIG
+
+=item TYPE_INIT
+
+=item TYPE_READ
+
+=item TYPE_WRITE
+
+=item TYPE_FLUSH
+
+=item TYPE_LOG
+
+=item TYPE_NOTIF
+
+=item TYPE_SHUTDOWN
+
+=item TYPE_DATASET
+
+=back
+
+I<name> is the name of the callback-function or the type of the data-set,
+depending on the value of I<type>. (Please note that the type of the data-set
+is the value passed as I<name> here and has nothing to do with the I<type>
+argument which simply tells B<plugin_register> what is being registered.)
+
+The last argument, I<data>, is either a function name or an array-reference.
+If I<type> is B<TYPE_DATASET>, then the I<data> argument must be an
+array-reference which points to an array of hashes. Each hash describes one
+data-set. For the exact layout see B<Data-Set> above. Please note that
+there is a large number of predefined data-sets available in the B<types.db>
+file which are automatically registered with collectd - see L<types.db(5)> for
+a description of the format of this file.
+
+B<Note>: Using B<plugin_register> to register a data-set is deprecated. Add
+the new type to a custom L<types.db(5)> file instead. This functionality might
+be removed in a future version of collectd.
+
+If the I<type> argument is any of the other types (B<TYPE_INIT>, B<TYPE_READ>,
+...) then I<data> is expected to be a function name. If the name is not
+prefixed with the plugin's package name collectd will add it automatically.
+The interface slightly differs from the C interface (which expects a function
+pointer instead) because Perl does not support to share references to
+subroutines between threads.
+
+These functions are called in the various stages of the daemon (see the
+section "WRITING YOUR OWN PLUGINS" above) and are passed the following
+arguments:
+
+=over 4
+
+=item TYPE_CONFIG
+
+The only argument passed is I<config-item>. See above for the layout of this
+data type.
+
+=item TYPE_INIT
+
+=item TYPE_READ
+
+=item TYPE_SHUTDOWN
+
+No arguments are passed.
+
+=item TYPE_WRITE
+
+The arguments passed are I<type>, I<data-set>, and I<value-list>. I<type> is a
+string. For the layout of I<data-set> and I<value-list> see above.
+
+=item TYPE_FLUSH
+
+The arguments passed are I<timeout> and I<identifier>. I<timeout> indicates
+that only data older than I<timeout> seconds is to be flushed. I<identifier>
+specifies which values are to be flushed.
+
+=item TYPE_LOG
+
+The arguments are I<log-level> and I<message>. The log level is small for
+important messages and high for less important messages. The least important
+level is B<LOG_DEBUG>, the most important level is B<LOG_ERR>. In between there
+are (from least to most important): B<LOG_INFO>, B<LOG_NOTICE>, and
+B<LOG_WARNING>. I<message> is simply a string B<without> a newline at the end.
+
+=item TYPE_NOTIF
+
+The only argument passed is I<notification>. See above for the layout of this
+data type.
+
+=back
+
+=item B<plugin_unregister> (I<type>, I<plugin>)
+
+Removes a callback or data-set from collectd's internal list of
+functionsE<nbsp>/ datasets.
+
+=item B<plugin_dispatch_values> (I<value-list>)
+
+Submits a I<value-list> to the daemon. If the data-set identified by
+I<value-list>->{I<type>}
+is found (and the number of values matches the number of data-sources) then the
+type, data-set and value-list is passed to all write-callbacks that are
+registered with the daemon.
+
+=item B<plugin_write> ([B<plugins> => I<...>][, B<datasets> => I<...>],
+B<valuelists> => I<...>)
+
+Calls the write function of the given I<plugins> with the provided I<data
+sets> and I<value lists>. In contrast to B<plugin_dispatch_values>, it does
+not update collectd's internal cache and bypasses the filter mechanism (see
+L<collectd.conf(5)> for details). If the B<plugins> argument has been omitted,
+the values will be dispatched to all registered write plugins. If the
+B<datasets> argument has been omitted, the required data sets are looked up
+according to the C<type> member in the appropriate value list. The value of
+all three arguments may either be a single scalar or a reference to an array.
+If the B<datasets> argument has been specified, the number of data sets has to
+equal the number of specified value lists.
+
+=item B<plugin_flush> ([B<timeout> => I<timeout>][, B<plugins> => I<...>][,
+B<identifiers> => I<...>])
+
+Flush one or more plugins. I<timeout> and the specified I<identifiers> are
+passed on to the registered flush-callbacks. If omitted, the timeout defaults
+to C<-1>. The identifier defaults to the undefined value. If the B<plugins>
+argument has been specified, only named plugins will be flushed. The value of
+the B<plugins> and B<identifiers> arguments may either be a string or a
+reference to an array of strings.
+
+=item B<plugin_dispatch_notification> (I<notification>)
+
+Submits a I<notification> to the daemon which will then pass it to all
+notification-callbacks that are registered.
+
+=item B<plugin_log> (I<log-level>, I<message>)
+
+Submits a I<message> of level I<log-level> to collectd's logging mechanism.
+The message is passed to all log-callbacks that are registered with collectd.
+
+=item B<ERROR>, B<WARNING>, B<NOTICE>, B<INFO>, B<DEBUG> (I<message>)
+
+Wrappers around B<plugin_log>, using B<LOG_ERR>, B<LOG_WARNING>,
+B<LOG_NOTICE>, B<LOG_INFO> and B<LOG_DEBUG> respectively as I<log-level>.
+
+=item B<plugin_get_interval> ()
+
+Returns the interval of the current plugin as a floating point number in
+seconds. This value depends on the interval configured within the
+C<LoadPlugin perl> block or the global interval (see L<collectd.conf(5)> for
+details).
+
+=back
+
+The following function provides the filter chain C-interface to Perl-modules.
+It is exported by the ":filter_chain" export tag (see the section "EXPORTS"
+below).
+
+=over 4
+
+=item B<fc_register> (I<type>, I<name>, I<proc>)
+
+Registers filter chain callbacks with collectd.
+
+I<type> may be any of:
+
+=over 4
+
+=item FC_MATCH
+
+=item FC_TARGET
+
+=back
+
+I<name> is the name of the match or target. By this name, the callbacks are
+identified in the configuration file when specifying a B<Match> or B<Target>
+block (see L<collectd.conf(5)> for details).
+
+I<proc> is a hash reference. The hash includes up to three callbacks: an
+optional constructor (B<create>) and destructor (B<destroy>) and a mandatory
+B<match> or B<invoke> callback. B<match> is called whenever processing an
+appropriate match, while B<invoke> is called whenever processing an
+appropriate target (see the section "FILTER CONFIGURATION" in
+L<collectd.conf(5)> for details). Just like any other callbacks, filter chain
+callbacks are identified by the function name rather than a function pointer
+because Perl does not support to share references to subroutines between
+threads. The following arguments are passed to the callbacks:
+
+=over 4
+
+=item create
+
+The arguments passed are I<config-item> and I<user-data>. See above for the
+layout of the config-item data-type. I<user-data> is a reference to a scalar
+value that may be used to store any information specific to this particular
+instance. The daemon does not care about this information at all. It's for the
+plugin's use only.
+
+=item destroy
+
+The only argument passed is I<user-data> which is a reference to the user data
+initialized in the B<create> callback. This callback may be used to cleanup
+instance-specific information and settings.
+
+=item match, invoke
+
+The arguments passed are I<data-set>, I<value-list>, I<meta> and I<user-data>.
+See above for the layout of the data-set and value-list data-types. I<meta> is
+a pointer to an array of meta information, just like the B<meta> member of the
+notification data-type (see above). I<user-data> is a reference to the user
+data initialized in the B<create> callback.

+
+=item B<$hostname_g>
+
+As the name suggests this variable keeps the hostname of the system collectd
+is running on. The value might be influenced by the B<Hostname> or
+B<FQDNLookup> configuration options (see L<collectd.conf(5)> for details).
+
+=item B<$interval_g>
+
+This variable keeps the interval in seconds in which the read functions are
+queried (see the B<Interval> configuration option).
+
+B<Note:> This variable should no longer be used in favor of
+C<plugin_get_interval()> (see above). This function takes any plugin-specific
+interval settings into account (see the C<Interval> option of C<LoadPlugin> in

+=head1 EXAMPLES
+
+Any Perl plugin will start similar to:
+
+  package Collectd::Plugins::FooBar;
+
+  use strict;
+  use warnings;
+
+  use Collectd qw( :all );
+
+A very simple read function might look like:
+
+  sub foobar_read
+  {
+    my $vl = { plugin => 'foobar', type => 'gauge' };
+    $vl->{'values'} = [ rand(42) ];
+    plugin_dispatch_values ($vl);
+    return 1;
+  }
+
+A very simple write function might look like:
+
+  sub foobar_write
+  {
+    my ($type, $ds, $vl) = @_;
+    for (my $i = 0; $i < scalar (@$ds); ++$i) {
+      print "$vl->{'plugin'} ($vl->{'type'}): $vl->{'values'}->[$i]\n";
+    }
+    return 1;
+  }
+
+A very simple match callback might look like:
+
+  sub foobar_match
+  {
+    my ($ds, $vl, $meta, $user_data) = @_;
+    if (matches($ds, $vl)) {
+      return FC_MATCH_MATCHES;
+    } else {
+      return FC_MATCH_NO_MATCH;
+    }
+  }
+
+To register those functions with collectd:
+
+  plugin_register (TYPE_READ, "foobar", "foobar_read");
+  plugin_register (TYPE_WRITE, "foobar", "foobar_write");
+
+  fc_register (FC_MATCH, "foobar", "foobar_match");
+
+See the section "DATA TYPES" above for a complete documentation of the data
+types used by the read, write and match functions.
+
+=head1 NOTES
+
+=over 4
+
+=item
+
+Please feel free to send in new plugins to collectd's mailing list at
+E<lt>collectdE<nbsp>atE<nbsp>collectd.orgE<gt> for review and, possibly,
+inclusion in the main distribution. In the latter case, we will take care of
+keeping the plugin up to date and adapting it to new versions of collectd.
+
+Before submitting your plugin, please take a look at
+L<http://collectd.org/dev-info.shtml>.
+
+=back
+
+=head1 CAVEATS
+
+=over 4
+
+=item
+
+collectd is heavily multi-threaded. Each collectd thread accessing the perl
+plugin will be mapped to a Perl interpreter thread (see L<threads(3perl)>).
+Any such thread will be created and destroyed transparently and on-the-fly.
+
+Hence, any plugin has to be thread-safe if it provides several entry points
+from collectd (i.E<nbsp>e. if it registers more than one callback or if a
+registered callback may be called more than once in parallel). Please note
+that no data is shared between threads by default. You have to use the
+B<threads::shared> module to do so.
+
+=item
+
+Each function name registered with collectd has to be available before the
+first thread has been created (i.E<nbsp>e. basically at compile time). This
+basically means that hacks (yes, I really consider this to be a hack) like
+C<*foo = \&bar; plugin_register (TYPE_READ, "plugin", "foo");> most likely
+will not work. This is due to the fact that the symbol table is not shared
+across different threads.
+
+=item
+
+Each plugin is usually only loaded once and kept in memory for performance
+reasons. Therefore, END blocks are only executed once when collectd shuts
+down. You should not rely on END blocks anyway - use B<shutdown functions>
+instead.
+
+=item
+
+The perl plugin exports the internal API of collectd which is considered
+unstable and subject to change at any time. We try hard to not break backwards
+compatibility in the Perl API during the life cycle of one major release.
+However, this cannot be guaranteed at all times. Watch out for warnings
+dispatched by the perl plugin after upgrades.
+
+=back
+
+=head1 KNOWN BUGS
+
+=over 4
+
+=item
+
+Currently, it is not possible to flush a single Perl plugin only. You can
+either flush all Perl plugins or none at all and you have to use C<perl> as
+plugin name when doing so.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \f(CW\*(C`python plugin\*(C'\fR embeds a Python-interpreter into collectd and provides an
+interface to collectd's plugin system. This makes it possible to write plugins
+for collectd in Python. This is a lot more efficient than executing a
+Python-script every time you want to read a value with the \f(CW\*(C`exec plugin\*(C'\fR (see
+\&\fIcollectd\-exec\fR\|(5)) and provides a lot more functionality, too.
+.PP
+The minimum required Python version is \fI2.3\fR.

+.IX Item "LoadPlugin Plugin"
+Loads the Python plugin \fIPlugin\fR.
+.IP "\fBEncoding\fR \fIName\fR" 4
+.IX Item "Encoding Name"
+The default encoding for Unicode objects you pass to collectd. If you omit this
+option it will default to \fBascii\fR on \fIPython 2\fR. On \fIPython 3\fR it will
+always be \fButf\-8\fR, as this function was removed, so this will be silently
+ignored.
+These defaults are hardcoded in Python and will ignore everything else,
+including your locale.
+.IP "\fBModulePath\fR \fIName\fR" 4
+.IX Item "ModulePath Name"
+Prepends \fIName\fR to \fBsys.path\fR. You won't be able to import any scripts you
+wrote unless they are located in one of the directories in this list. Please
+note that it only has effect on plugins loaded after this option. You can
+use multiple \fBModulePath\fR lines to add more than one directory.
+.IP "\fBLogTraces\fR \fIbool\fR" 4
+.IX Item "LogTraces bool"
+If a Python script throws an exception it will be logged by collectd with the
+name of the exception and the message. If you set this option to true it will
+also log the full stacktrace just like the default output of an interactive
+Python interpreter. This should probably be set to false most of the time but
+is very useful for development and debugging of new modules.
+.IP "\fBInteractive\fR \fIbool\fR" 4
+.IX Item "Interactive bool"
+This option will cause the module to launch an interactive Python interpreter
+that reads from and writes to the terminal. Note that collectd will terminate
+right after starting up if you try to run it as a daemon while this option is
+enabled so make sure to start collectd with the \fB\-f\fR option.
+.Sp
+The \fBcollectd\fR module is \fInot\fR imported into the interpreter's globals. You
+have to do it manually. Be sure to read the help text of the module, it can be
+used as a reference guide during coding.
+.Sp
+This interactive session will behave slightly differently from a daemonized
+collectd script as well as from a normal Python interpreter:
+.RS 4
+.IP "\(bu" 4
+\&\fB1.\fR collectd will try to import the \fBreadline\fR module to give you a decent
+way of entering your commands. The daemonized collectd won't do that.
+.IP "\(bu" 4
+\&\fB2.\fR collectd will block \fI\s-1SIGINT\s0\fR. Pressing \fICtrl+C\fR will usually cause
+collectd to shut down. This would be problematic in an interactive session,
+therefore this signal will be blocked. You can still use it to interrupt
+syscalls like sleep and pause but it won't generate a \fIKeyboardInterrupt\fR
+exception either.
+.Sp
+To quit collectd send \fI\s-1EOF\s0\fR (press \fICtrl+D\fR at the beginning of a new line).
+.IP "\(bu" 4
+\&\fB3.\fR collectd handles \fI\s-1SIGCHLD\s0\fR. This means that Python won't be able to
+determine the return code of spawned processes with \fIsystem()\fR, \fIpopen()\fR and
+subprocess. This will result in Python not using external programs like less
+to display help texts. You can override this behavior with the \fB\s-1PAGER\s0\fR
+environment variable, e.g. \fIexport PAGER=less\fR before starting collectd.
+Depending on your version of Python this might or might not result in an
+\&\fBOSError\fR exception which can be ignored.
+.Sp
+If you really need to spawn new processes from Python you can register an init
+callback and reset the action for \s-1SIGCHLD\s0 to the default behavior. Please note
+that this \fIwill\fR break the exec plugin. Do not even load the exec plugin if
+you intend to do this!
+.Sp
+There is an example script located in \fBcontrib/python/getsigchld.py\fR  to do
+this. If you import this from \fIcollectd.conf\fR \s-1SIGCHLD\s0 will be handled
+normally and spawning processes from Python will work as intended.
+.RE
+.RS 4
+.RE
+.IP "<\fBModule\fR \fIName\fR> block" 4
+.IX Item "<Module Name> block"
+This block may be used to pass on configuration settings to a Python module.
+The configuration is converted into an instance of the \fBConfig\fR class which is
+passed to the registered configuration callback. See below for details about
+the \fBConfig\fR class and how to register callbacks.
+.Sp
+The \fIname\fR identifies the callback.
+.SH "STRINGS"
+.IX Header "STRINGS"
+There are a lot of places where strings are sent from collectd to Python and
+from Python to collectd. How exactly this works depends on whether byte or
+unicode strings or Python2 or Python3 are used.
+.PP
+Python2 has \fIstr\fR, which is just bytes, and \fIunicode\fR. Python3 has \fIstr\fR,
+which is a unicode object, and \fIbytes\fR.
+.PP
+When passing strings from Python to collectd all of these object are supported
+in all places, however \fIstr\fR should be used if possible. These strings must
+not contain a \s-1NUL\s0 byte. Ignoring this will result in a \fITypeError\fR exception.
+If a byte string was used it will be used as is by collectd. If a unicode
+object was used it will be encoded using the default encoding (see above). If
+this is not possible Python will raise a \fIUnicodeEncodeError\fR exception.
+.PP
+When passing strings from collectd to Python the behavior depends on the
+Python version used. Python2 will always receive a \fIstr\fR object. Python3 will
+usually receive a \fIstr\fR object as well, however the original string will be
+decoded to unicode using the default encoding. If this fails because the
+string is not a valid sequence for this encoding a \fIbytes\fR object will be
+returned instead.
+.SH "WRITING YOUR OWN PLUGINS"
+.IX Header "WRITING YOUR OWN PLUGINS"
+Writing your own plugins is quite simple. collectd manages plugins by means of
+\&\fBdispatch functions\fR which call the appropriate \fBcallback functions\fR
+registered by the plugins. Any plugin basically consists of the implementation
+of these callback functions and initializing code which registers the
+functions with collectd. See the section \*(L"\s-1EXAMPLES\*(R"\s0 below for a really basic
+example. The following types of \fBcallback functions\fR are known to collectd
+(all of them are optional):
+.IP "configuration functions" 4
+.IX Item "configuration functions"
+These are called during configuration if an appropriate
+\&\fBModule\fR block has been encountered. It is called once for each \fBModule\fR
+block which matches the name of the callback as provided with the
+\&\fBregister_config\fR method \- see below.
+.Sp
+Python thread support has not been initialized at this point so do not use any
+threading functions here!
+.IP "init functions" 4
+.IX Item "init functions"
+These are called once after loading the module and before any
+calls to the read and write functions. It should be used to initialize the
+internal state of the plugin (e.\ g. open sockets, ...). This is the
+earliest point where you may use threads.
+.IP "read functions" 4
+.IX Item "read functions"
+These are used to collect the actual data. It is called once
+per interval (see the \fBInterval\fR configuration option of collectd). Usually
+it will call \fBplugin_dispatch_values\fR to dispatch the values to collectd
+which will pass them on to all registered \fBwrite functions\fR. If this function
+throws any kind of exception the plugin will be skipped for an increasing
+amount of time until it returns normally again.
+.IP "write functions" 4
+.IX Item "write functions"
+These are used to write the dispatched values. It is called
+once for every value that was dispatched by any plugin.
+.IP "flush functions" 4
+.IX Item "flush functions"
+These are used to flush internal caches of plugins. It is
+usually triggered by the user only. Any plugin which caches data before
+writing it to disk should provide this kind of callback function.
+.IP "log functions" 4
+.IX Item "log functions"
+These are used to pass messages of plugins or the daemon itself
+to the user.
+.IP "notification function" 4
+.IX Item "notification function"
+These are used to act upon notifications. In general, a
+notification is a status message that may be associated with a data instance.
+Usually, a notification is generated by the daemon if a configured threshold
+has been exceeded (see the section \*(L"\s-1THRESHOLD CONFIGURATION\*(R"\s0 in
+\&\fIcollectd.conf\fR\|(5) for more details), but any plugin may dispatch
+notifications as well.
+.IP "shutdown functions" 4
+.IX Item "shutdown functions"
+These are called once before the daemon shuts down. It should
+be used to clean up the plugin (e.g. close sockets, ...).
+.PP
+Any function (except log functions) may throw an exception in case of
+errors. The exception will be passed on to the user using collectd's logging
+mechanism. If a log callback throws an exception it will be printed to standard
+error instead.
+.PP
+See the documentation of the various \fBregister_\fR methods in the section
+\&\*(L"\s-1FUNCTIONS\*(R"\s0 below for the number and types of arguments passed to each
+\&\fBcallback function\fR. This section also explains how to register \fBcallback
+functions\fR with collectd.
+.PP
+To enable a module, copy it to a place where Python can find it (i.\ e. a
+directory listed in \fBsys.path\fR) just as any other Python plugin and add
+an appropriate \fBImport\fR option to the configuration file. After restarting
+collectd you're done.
+.SH "CLASSES"
+.IX Header "CLASSES"
+The following complex types are used to pass values between the Python plugin
+and collectd:
+.SS "Signed"
+.IX Subsection "Signed"
+The Signed class is just a long. It has all its methods and behaves exactly
+like any other long object. It is used to indicate if an integer was or should
+be stored as a signed or unsigned integer object.
+.PP
+.Vb 1
+\& class Signed(long)
+.Ve
+.PP
+This is a long by another name. Use it in meta data dicts
+to choose the way it is stored in the meta data.
+.SS "Unsigned"
+.IX Subsection "Unsigned"
+The Unsigned class is just a long. It has all its methods and behaves exactly
+like any other long object. It is used to indicate if an integer was or should
+be stored as a signed or unsigned integer object.
+.PP
+.Vb 1
+\& class Unsigned(long)
+.Ve
+.PP
+This is a long by another name. Use it in meta data dicts
+to choose the way it is stored in the meta data.
+.SS "Config"
+.IX Subsection "Config"
+The Config class is an object which keeps the information provided in the
+configuration file. The sequence of children keeps one entry for each
+configuration option. Each such entry is another Config instance, which
+may nest further if nested blocks are used.
+.PP
+.Vb 1
+\& class Config(object)
+.Ve
+.PP
+This represents a piece of collectd's config file. It is passed to scripts with
+config callbacks (see \fBregister_config\fR) and is of little use if created
+somewhere else.
+.PP
+It has no methods beyond the bare minimum and only exists for its data members.
+.PP
+Data descriptors defined here:
+.IP "parent" 4
+.IX Item "parent"
+This represents the parent of this node. On the root node
+of the config tree it will be None.
+.IP "key" 4
+.IX Item "key"
+This is the keyword of this item, i.e. the first word of any given line in the
+config file. It will always be a string.
+.IP "values" 4
+.IX Item "values"
+This is a tuple (which might be empty) of all value, i.e. words following the
+keyword in any given line in the config file.
+.Sp
+Every item in this tuple will be either a string, a float or a boolean,
+depending on the contents of the configuration file.
+.IP "children" 4
+.IX Item "children"
+This is a tuple of child nodes. For most nodes this will be empty. If this node
+represents a block instead of a single line of the config file it will contain
+all nodes in this block.

+This is the Unix timestamp of the time this value was read. For dispatching
+values this can be set to zero which means \*(L"now\*(R". This means the time the value
+is actually dispatched, not the time it was set to 0.
+.IP "type" 4
+.IX Item "type"
+The type of this value. This type has to be defined in your \fItypes.db\fR.
+Attempting to set it to any other value will raise a \fITypeError\fR exception.
+Assigning a type is mandatory, calling dispatch without doing so will raise a

+Data descriptors defined here:
+.IP "interval" 4
+.IX Item "interval"
+The interval is the timespan in seconds between two submits for the same data
+source. This value has to be a positive integer, so you can't submit more than
+one value per second. If this member is set to a non-positive value, the
+default value as specified in the config file will be used (default: 10).
+.Sp
+If you submit values more often than the specified interval, the average will
+be used. If you submit less values, your graphs will have gaps.
+.IP "values" 4
+.IX Item "values"
+These are the actual values that get dispatched to collectd. It has to be a
+sequence (a tuple or list) of numbers. The size of the sequence and the type of
+its content depend on the type member your \fItypes.db\fR file. For more
+information on this read the \fItypes.db\fR\|(5) manual page.
+.Sp
+If the sequence does not have the correct size upon dispatch a \fIRuntimeError\fR
+exception will be raised. If the content of the sequence is not a number, a
+\&\fITypeError\fR exception will be raised.
+.IP "meta" 4
+.IX Item "meta"
+These are the meta data for this Value object.
+It has to be a dictionary of numbers, strings or bools. All keys must be
+strings. \fIint\fR and <long> objects will be dispatched as signed integers unless
+they are between 2**63 and 2**64\-1, which will result in a unsigned integer.
+You can force one of these storage classes by using the classes
+\&\fBcollectd.Signed\fR and \fBcollectd.Unsigned\fR. A meta object received by a write
+callback will always contain \fBSigned\fR or \fBUnsigned\fR objects.

+
+=head1 DESCRIPTION
+
+The C<python plugin> embeds a Python-interpreter into collectd and provides an
+interface to collectd's plugin system. This makes it possible to write plugins
+for collectd in Python. This is a lot more efficient than executing a
+Python-script every time you want to read a value with the C<exec plugin> (see
+L<collectd-exec(5)>) and provides a lot more functionality, too.
+
+The minimum required Python version is I<2.3>.
+
+=head1 CONFIGURATION
+
+=over 4
+
+=item B<LoadPlugin> I<Plugin>
+
+Loads the Python plugin I<Plugin>.
+
+=item B<Encoding> I<Name>
+
+The default encoding for Unicode objects you pass to collectd. If you omit this
+option it will default to B<ascii> on I<Python 2>. On I<Python 3> it will
+always be B<utf-8>, as this function was removed, so this will be silently
+ignored.
+These defaults are hardcoded in Python and will ignore everything else,
+including your locale.
+
+=item B<ModulePath> I<Name>
+
+Prepends I<Name> to B<sys.path>. You won't be able to import any scripts you
+wrote unless they are located in one of the directories in this list. Please
+note that it only has effect on plugins loaded after this option. You can
+use multiple B<ModulePath> lines to add more than one directory.
+
+=item B<LogTraces> I<bool>
+
+If a Python script throws an exception it will be logged by collectd with the
+name of the exception and the message. If you set this option to true it will
+also log the full stacktrace just like the default output of an interactive
+Python interpreter. This should probably be set to false most of the time but
+is very useful for development and debugging of new modules.
+
+=item B<Interactive> I<bool>
+
+This option will cause the module to launch an interactive Python interpreter
+that reads from and writes to the terminal. Note that collectd will terminate
+right after starting up if you try to run it as a daemon while this option is
+enabled so make sure to start collectd with the B<-f> option.
+
+The B<collectd> module is I<not> imported into the interpreter's globals. You
+have to do it manually. Be sure to read the help text of the module, it can be
+used as a reference guide during coding.
+
+This interactive session will behave slightly differently from a daemonized
+collectd script as well as from a normal Python interpreter:
+
+=over 4
+
+=item
+
+B<1.> collectd will try to import the B<readline> module to give you a decent
+way of entering your commands. The daemonized collectd won't do that.
+
+=item
+
+B<2.> collectd will block I<SIGINT>. Pressing I<Ctrl+C> will usually cause
+collectd to shut down. This would be problematic in an interactive session,
+therefore this signal will be blocked. You can still use it to interrupt
+syscalls like sleep and pause but it won't generate a I<KeyboardInterrupt>
+exception either.
+
+To quit collectd send I<EOF> (press I<Ctrl+D> at the beginning of a new line).
+
+=item
+
+B<3.> collectd handles I<SIGCHLD>. This means that Python won't be able to
+determine the return code of spawned processes with system(), popen() and
+subprocess. This will result in Python not using external programs like less
+to display help texts. You can override this behavior with the B<PAGER>
+environment variable, e.g. I<export PAGER=less> before starting collectd.
+Depending on your version of Python this might or might not result in an
+B<OSError> exception which can be ignored.
+
+If you really need to spawn new processes from Python you can register an init
+callback and reset the action for SIGCHLD to the default behavior. Please note
+that this I<will> break the exec plugin. Do not even load the exec plugin if
+you intend to do this!
+
+There is an example script located in B<contrib/python/getsigchld.py>  to do
+this. If you import this from I<collectd.conf> SIGCHLD will be handled
+normally and spawning processes from Python will work as intended.
+
+=back
+
+=item E<lt>B<Module> I<Name>E<gt> block
+
+This block may be used to pass on configuration settings to a Python module.
+The configuration is converted into an instance of the B<Config> class which is
+passed to the registered configuration callback. See below for details about
+the B<Config> class and how to register callbacks.
+
+The I<name> identifies the callback.
+
+=back
+
+=head1 STRINGS
+
+There are a lot of places where strings are sent from collectd to Python and
+from Python to collectd. How exactly this works depends on whether byte or
+unicode strings or Python2 or Python3 are used.
+
+Python2 has I<str>, which is just bytes, and I<unicode>. Python3 has I<str>,
+which is a unicode object, and I<bytes>.
+
+When passing strings from Python to collectd all of these object are supported
+in all places, however I<str> should be used if possible. These strings must
+not contain a NUL byte. Ignoring this will result in a I<TypeError> exception.
+If a byte string was used it will be used as is by collectd. If a unicode
+object was used it will be encoded using the default encoding (see above). If
+this is not possible Python will raise a I<UnicodeEncodeError> exception.
+
+When passing strings from collectd to Python the behavior depends on the
+Python version used. Python2 will always receive a I<str> object. Python3 will
+usually receive a I<str> object as well, however the original string will be
+decoded to unicode using the default encoding. If this fails because the
+string is not a valid sequence for this encoding a I<bytes> object will be
+returned instead.
+
+=head1 WRITING YOUR OWN PLUGINS
+
+Writing your own plugins is quite simple. collectd manages plugins by means of
+B<dispatch functions> which call the appropriate B<callback functions>
+registered by the plugins. Any plugin basically consists of the implementation
+of these callback functions and initializing code which registers the
+functions with collectd. See the section "EXAMPLES" below for a really basic
+example. The following types of B<callback functions> are known to collectd
+(all of them are optional):
+
+=over 4
+
+=item configuration functions
+
+These are called during configuration if an appropriate
+B<Module> block has been encountered. It is called once for each B<Module>
+block which matches the name of the callback as provided with the
+B<register_config> method - see below.
+
+Python thread support has not been initialized at this point so do not use any
+threading functions here!
+
+=item init functions
+
+These are called once after loading the module and before any
+calls to the read and write functions. It should be used to initialize the
+internal state of the plugin (e.E<nbsp>g. open sockets, ...). This is the
+earliest point where you may use threads.
+
+=item read functions
+
+These are used to collect the actual data. It is called once
+per interval (see the B<Interval> configuration option of collectd). Usually
+it will call B<plugin_dispatch_values> to dispatch the values to collectd
+which will pass them on to all registered B<write functions>. If this function
+throws any kind of exception the plugin will be skipped for an increasing
+amount of time until it returns normally again.
+
+=item write functions
+
+These are used to write the dispatched values. It is called
+once for every value that was dispatched by any plugin.
+
+=item flush functions
+
+These are used to flush internal caches of plugins. It is
+usually triggered by the user only. Any plugin which caches data before
+writing it to disk should provide this kind of callback function.
+
+=item log functions
+
+These are used to pass messages of plugins or the daemon itself
+to the user.
+
+=item notification function
+
+These are used to act upon notifications. In general, a
+notification is a status message that may be associated with a data instance.
+Usually, a notification is generated by the daemon if a configured threshold
+has been exceeded (see the section "THRESHOLD CONFIGURATION" in
+L<collectd.conf(5)> for more details), but any plugin may dispatch
+notifications as well.
+
+=item shutdown functions
+
+These are called once before the daemon shuts down. It should
+be used to clean up the plugin (e.g. close sockets, ...).
+
+=back
+
+Any function (except log functions) may throw an exception in case of
+errors. The exception will be passed on to the user using collectd's logging
+mechanism. If a log callback throws an exception it will be printed to standard
+error instead.
+
+See the documentation of the various B<register_> methods in the section
+"FUNCTIONS" below for the number and types of arguments passed to each
+B<callback function>. This section also explains how to register B<callback
+functions> with collectd.
+
+To enable a module, copy it to a place where Python can find it (i.E<nbsp>e. a
+directory listed in B<sys.path>) just as any other Python plugin and add
+an appropriate B<Import> option to the configuration file. After restarting
+collectd you're done.
+
+=head1 CLASSES
+
+The following complex types are used to pass values between the Python plugin
+and collectd:
+
+=head2 Signed
+
+The Signed class is just a long. It has all its methods and behaves exactly
+like any other long object. It is used to indicate if an integer was or should
+be stored as a signed or unsigned integer object.
+
+ class Signed(long)
+
+This is a long by another name. Use it in meta data dicts
+to choose the way it is stored in the meta data.
+
+=head2 Unsigned
+
+The Unsigned class is just a long. It has all its methods and behaves exactly
+like any other long object. It is used to indicate if an integer was or should
+be stored as a signed or unsigned integer object.
+
+ class Unsigned(long)
+
+This is a long by another name. Use it in meta data dicts
+to choose the way it is stored in the meta data.
+
+=head2 Config
+
+The Config class is an object which keeps the information provided in the
+configuration file. The sequence of children keeps one entry for each
+configuration option. Each such entry is another Config instance, which
+may nest further if nested blocks are used.
+
+ class Config(object)
+
+This represents a piece of collectd's config file. It is passed to scripts with
+config callbacks (see B<register_config>) and is of little use if created
+somewhere else.
+
+It has no methods beyond the bare minimum and only exists for its data members.
+
+Data descriptors defined here:
+
+=over 4
+
+=item parent
+
+This represents the parent of this node. On the root node
+of the config tree it will be None.
+
+=item key
+
+This is the keyword of this item, i.e. the first word of any given line in the
+config file. It will always be a string.
+
+=item values
+
+This is a tuple (which might be empty) of all value, i.e. words following the
+keyword in any given line in the config file.
+
+Every item in this tuple will be either a string, a float or a boolean,
+depending on the contents of the configuration file.
+
+=item children
+
+This is a tuple of child nodes. For most nodes this will be empty. If this node
+represents a block instead of a single line of the config file it will contain
+all nodes in this block.
+
+=back
+
+=head2 PluginData
+
+This should not be used directly but it is the base class for both Values and
+Notification. It is used to identify the source of a value or notification.
+
+ class PluginData(object)
+
+This is an internal class that is the base for Values and Notification. It is
+pretty useless by itself and was therefore not exported to the collectd module.
+
+Data descriptors defined here:
+
+=over 4
+
+=item host
+
+The hostname of the host this value was read from. For dispatching this can be
+set to an empty string which means the local hostname as defined in
+collectd.conf.
+
+=item plugin
+
+The name of the plugin that read the data. Setting this member to an empty
+string will insert "python" upon dispatching.
+
+=item plugin_instance
+
+Plugin instance string. May be empty.
+
+=item time
+
+This is the Unix timestamp of the time this value was read. For dispatching
+values this can be set to zero which means "now". This means the time the value
+is actually dispatched, not the time it was set to 0.
+
+=item type
+
+The type of this value. This type has to be defined in your I<types.db>.
+Attempting to set it to any other value will raise a I<TypeError> exception.
+Assigning a type is mandatory, calling dispatch without doing so will raise a
+I<RuntimeError> exception.
+
+=item type_instance
+
+Type instance string. May be empty.
+
+=back
+
+=head2 Values
+
+A Value is an object which features a sequence of values. It is based on the
+I<PluginData> type and uses its members to identify the values.
+
+ class Values(PluginData)
+
+A Values object used for dispatching values to collectd and receiving values
+from write callbacks.

+
+Methods defined here:
+
+=over 4
+
+=item B<dispatch>([type][, values][, plugin_instance][, type_instance][, plugin][, host][, time][, interval]) -> None.
+
+Dispatch this instance to the collectd process. The object has members for each
+of the possible arguments for this method. For a detailed explanation of these
+parameters see the member of the same same.
+
+If you do not submit a parameter the value saved in its member will be
+submitted. If you do provide a parameter it will be used instead, without
+altering the member.
+
+=item B<write>([destination][, type][, values][, plugin_instance][, type_instance][, plugin][, host][, time][, interval]) -> None.
+
+Write this instance to a single plugin or all plugins if "destination" is
+omitted. This will bypass the main collectd process and all filtering and
+caching. Other than that it works similar to "dispatch". In most cases
+"dispatch" should be used instead of "write".
+
+=back
+
+Data descriptors defined here:
+
+=over 4
+
+=item interval
+
+The interval is the timespan in seconds between two submits for the same data
+source. This value has to be a positive integer, so you can't submit more than
+one value per second. If this member is set to a non-positive value, the
+default value as specified in the config file will be used (default: 10).
+
+If you submit values more often than the specified interval, the average will
+be used. If you submit less values, your graphs will have gaps.
+
+=item values
+
+These are the actual values that get dispatched to collectd. It has to be a
+sequence (a tuple or list) of numbers. The size of the sequence and the type of
+its content depend on the type member your I<types.db> file. For more
+information on this read the L<types.db(5)> manual page.
+
+If the sequence does not have the correct size upon dispatch a I<RuntimeError>
+exception will be raised. If the content of the sequence is not a number, a
+I<TypeError> exception will be raised.
+
+=item meta
+
+These are the meta data for this Value object.
+It has to be a dictionary of numbers, strings or bools. All keys must be
+strings. I<int> and <long> objects will be dispatched as signed integers unless
+they are between 2**63 and 2**64-1, which will result in a unsigned integer.
+You can force one of these storage classes by using the classes
+B<collectd.Signed> and B<collectd.Unsigned>. A meta object received by a write
+callback will always contain B<Signed> or B<Unsigned> objects.
+
+=back
+
+=head2 Notification
+
+A notification is an object defining the severity and message of the status
+message as well as an identification of a data instance by means of the members
+of I<PluginData> on which it is based.
+
+class Notification(PluginData)
+The Notification class is a wrapper around the collectd notification.
+It can be used to notify other plugins about bad stuff happening. It works
+similar to Values but has a severity and a message instead of interval
+and time.
+Notifications can be dispatched at any time and can be received with
+register_notification.

+=head1 FUNCTIONS
+
+The following functions provide the C-interface to Python-modules.
+
+=over 4
+
+=item B<register_*>(I<callback>[, I<data>][, I<name>]) -> identifier
+
+There are eight different register functions to get callback for eight
+different events. With one exception all of them are called as shown above.
+
+=over 4
+
+=item
+
+I<callback> is a callable object that will be called every time the event is
+triggered.
+
+=item
+
+I<data> is an optional object that will be passed back to the callback function
+every time it is called. If you omit this parameter no object is passed back to
+your callback, not even None.
+
+=item
+
+I<name> is an optional identifier for this callback. The default name is
+B<python>.I<module>. I<module> is taken from the B<__module__> attribute of
+your callback function. Every callback needs a unique identifier, so if you
+want to register the same callback multiple times in the same module you need to
+specify a name here. Otherwise it's safe to ignore this parameter.
+
+=item
+
+I<identifier> is the full identifier assigned to this callback.
+
+=back
+
+These functions are called in the various stages of the daemon (see the section
+L<"WRITING YOUR OWN PLUGINS"> above) and are passed the following arguments:
+
+=over 4
+
+=item register_config
+
+The only argument passed is a I<Config> object. See above for the layout of this
+data type.
+Note that you cannot receive the whole config files this way, only B<Module>
+blocks inside the Python configuration block. Additionally you will only
+receive blocks where your callback identifier matches B<python.>I<blockname>.
+
+=item register_init
+
+The callback will be called without arguments.
+
+=item register_read(callback[, interval][, data][, name]) -> I<identifier>
+
+This function takes an additional parameter: I<interval>. It specifies the
+time between calls to the callback function.
+
+The callback will be called without arguments.
+
+=item register_shutdown
+
+The callback will be called without arguments.
+
+=item register_write
+
+The callback function will be called with one argument passed, which will be a
+I<Values> object. For the layout of I<Values> see above.
+If this callback function throws an exception the next call will be delayed by
+an increasing interval.
+
+=item register_flush
+
+Like B<register_config> is important for this callback because it determines
+what flush requests the plugin will receive.
+
+The arguments passed are I<timeout> and I<identifier>. I<timeout> indicates
+that only data older than I<timeout> seconds is to be flushed. I<identifier>
+specifies which values are to be flushed.
+
+=item register_log
+
+The arguments are I<severity> and I<message>. The severity is an integer and
+small for important messages and high for less important messages. The least
+important level is B<LOG_DEBUG>, the most important level is B<LOG_ERR>. In
+between there are (from least to most important): B<LOG_INFO>, B<LOG_NOTICE>,
+and B<LOG_WARNING>. I<message> is simply a string B<without> a newline at the
+end.
+
+If this callback throws an exception it will B<not> be logged. It will just be
+printed to B<sys.stderr> which usually means silently ignored.
+
+=item register_notification
+
+The only argument passed is a I<Notification> object. See above for the layout of this
+data type.
+
+=back
+
+=item B<unregister_*>(I<identifier>) -> None
+
+Removes a callback or data-set from collectd's internal list of callback
+functions. Every I<register_*> function has an I<unregister_*> function.
+I<identifier> is either the string that was returned by the register function
+or a callback function. The identifier will be constructed in the same way as
+for the register functions.
+
+=item B<get_dataset>(I<name>) -> I<definition>
+
+Returns the definition of a dataset specified by I<name>. I<definition> is a list
+of tuples, each representing one data source. Each tuple has 4 values:
+
+=over 4
+
+=item name
+
+A string, the name of the data source.
+
+=item type
+
+A string that is equal to either of the variables B<DS_TYPE_COUNTER>,
+B<DS_TYPE_GAUGE>, B<DS_TYPE_DERIVE> or B<DS_TYPE_ABSOLUTE>.
+
+=item min
+
+A float or None, the minimum value.
+
+=item max
+
+A float or None, the maximum value.
+
+=back
+
+=item B<flush>(I<plugin>[, I<timeout>][, I<identifier>]) -> None
+
+Flush one or all plugins. I<timeout> and the specified I<identifiers> are
+passed on to the registered flush-callbacks. If omitted, the timeout defaults
+to C<-1>. The identifier defaults to None. If the B<plugin> argument has been
+specified, only named plugin will be flushed.
+
+=item B<error>, B<warning>, B<notice>, B<info>, B<debug>(I<message>)
+
+Log a message with the specified severity.
+
+=back
+
+=head1 EXAMPLES
+
+Any Python module will start similar to:
+
+  import collectd
+
+A very simple read function might look like:
+
+  def read(data=None):
+    vl = collectd.Values(type='gauge')
+    vl.plugin='python.spam'
+    vl.dispatch(values=[random.random() * 100])
+
+A very simple write function might look like:
+
+  def write(vl, data=None):
+    for i in vl.values:
+      print "%s (%s): %f" % (vl.plugin, vl.type, i)
+
+To register those functions with collectd:
+
+  collectd.register_read(read);
+  collectd.register_write(write);
+
+See the section L<"CLASSES"> above for a complete documentation of the data
+types used by the read, write and match functions.
+
+=head1 NOTES
+
+=over 4
+
+=item
+
+Please feel free to send in new plugins to collectd's mailing list at
+E<lt>collectdE<nbsp>atE<nbsp>collectd.orgE<gt> for review and, possibly,
+inclusion in the main distribution. In the latter case, we will take care of
+keeping the plugin up to date and adapting it to new versions of collectd.
+
+Before submitting your plugin, please take a look at
+L<http://collectd.org/dev-info.shtml>.
+
+=back
+
+=head1 CAVEATS
+
+=over 4
+
+=item
+
+collectd is heavily multi-threaded. Each collectd thread accessing the Python
+plugin will be mapped to a Python interpreter thread. Any such thread will be
+created and destroyed transparently and on-the-fly.
+
+Hence, any plugin has to be thread-safe if it provides several entry points
+from collectd (i.E<nbsp>e. if it registers more than one callback or if a
+registered callback may be called more than once in parallel).
+
+=item
+
+The Python thread module is initialized just before calling the init callbacks.
+This means you must not use Python's threading module prior to this point. This
+includes all config and possibly other callback as well.
+
+=item
+
+The python plugin exports the internal API of collectd which is considered
+unstable and subject to change at any time. We try hard to not break backwards
+compatibility in the Python API during the life cycle of one major release.
+However, this cannot be guaranteed at all times. Watch out for warnings
+dispatched by the python plugin after upgrades.
+
+=back
+
+=head1 KNOWN BUGS
+
+=over 4
+
+=item
+
+Not all aspects of the collectd API are accessible from Python. This includes
+but is not limited to filters and data sets.

+used to query hosts in parallel. Depending on the number of hosts between one
+and ten threads are used.
+.SH "CONFIGURATION"
+.IX Header "CONFIGURATION"
+Since the aim of the \f(CW\*(C`snmp plugin\*(C'\fR is to provide a generic interface to \s-1SNMP,\s0
+it's configuration is not trivial and may take some time.
+.PP
+Since the \f(CW\*(C`Net\-SNMP\*(C'\fR library is used you can use all the environment variables
+that are interpreted by that package. See \fIsnmpcmd\fR\|(1) for more details.
+.PP
+There are two types of blocks that can be contained in the
+\&\f(CW\*(C`<Plugin\ snmp>\*(C'\fR block: \fBData\fR and \fBHost\fR:
+.SS "The \fBData\fP block"
+.IX Subsection "The Data block"
+The \fBData\fR block defines a list of values or a table of values that are to be
+queried. The following options can be set:
+.IP "\fBType\fR \fItype\fR" 4
+.IX Item "Type type"
+collectd's type that is to be used, e.\ g. \*(L"if_octets\*(R" for interface
+traffic or \*(L"users\*(R" for a user count. The types are read from the \fBTypesDB\fR
+(see \fIcollectd.conf\fR\|(5)), so you may want to check for which types are
+defined. See \fItypes.db\fR\|(5) for a description of the format of this file.
+.IP "\fBTable\fR \fItrue|false\fR" 4
+.IX Item "Table true|false"
+Define if this is a single list of values or a table of values. The difference
+is the following:
+.Sp
+When \fBTable\fR is set to \fBfalse\fR, the OIDs given to \fBValues\fR (see below) are
+queried using the \f(CW\*(C`GET\*(C'\fR \s-1SNMP\s0 command (see \fIsnmpget\fR\|(1)) and transmitted to
+collectd. \fBOne\fR value list is dispatched and, eventually, one file will be
+written.
+.Sp
+When \fBTable\fR is set to \fBtrue\fR, the OIDs given to \fBValues\fR (see below) are
+queried using the \f(CW\*(C`GETNEXT\*(C'\fR \s-1SNMP\s0 command until the subtree is left. After all
+the lists (think: all columns of the table) have been read \fBseveral\fR values
+sets will be dispatches and, eventually, several files will be written. If you
+configure a \fBType\fR (see above) which needs more than one data source (for
+example \f(CW\*(C`if_octets\*(C'\fR which needs \f(CW\*(C`rx\*(C'\fR and \f(CW\*(C`tx\*(C'\fR) you will need to specify more
+than one (two, in the example case) OIDs with the \fBValues\fR option. This has
+nothing to do with the \fBTable\fR setting.
+.Sp
+For example, if you want to query the number of users on a system, you can use
+\&\f(CW\*(C`HOST\-RESOURCES\-MIB::hrSystemNumUsers.0\*(C'\fR. This is one value and belongs to one
+value list, therefore \fBTable\fR must be set to \fBfalse\fR. Please note that, in
+this case, you have to include the sequence number (zero in this case) in the
+\&\s-1OID.\s0
+.Sp
+Counter example: If you want to query the interface table provided by the
+\&\f(CW\*(C`IF\-MIB\*(C'\fR, e.\ g. the bytes transmitted. There are potentially many
+interfaces, so you will want to set \fBTable\fR to \fBtrue\fR. Because the
+\&\f(CW\*(C`if_octets\*(C'\fR type needs two values, received and transmitted bytes, you need to
+specify two OIDs in the \fBValues\fR setting, in this case likely
+\&\f(CW\*(C`IF\-MIB::ifHCInOctets\*(C'\fR and \f(CW\*(C`IF\-MIB::ifHCOutOctets\*(C'\fR. But, this is because of
+the \fBType\fR setting, not the \fBTable\fR setting.
+.Sp
+Since the semantic of \fBInstance\fR and \fBValues\fR depends on this setting you
+need to set it before setting them. Doing vice verse will result in undefined
+behavior.
+.IP "\fBInstance\fR \fIInstance\fR" 4
+.IX Item "Instance Instance"
+Sets the type-instance of the values that are dispatched. The meaning of this
+setting depends on whether \fBTable\fR is set to \fItrue\fR or \fIfalse\fR:
+.Sp
+If \fBTable\fR is set to \fItrue\fR, \fIInstance\fR is interpreted as an SNMP-prefix
+that will return a list of values. Those values are then used as the actual
+type-instance. An example would be the \f(CW\*(C`IF\-MIB::ifDescr\*(C'\fR subtree.
+\&\fIvariables\fR\|(5) from the \s-1SNMP\s0 distribution describes the format of OIDs.
+.Sp
+If \fBTable\fR is set to \fItrue\fR and \fBInstance\fR is omitted, then \*(L"\s-1SUBID\*(R"\s0 will be
+used as the instance.
+.Sp
+If \fBTable\fR is set to \fIfalse\fR the actual string configured for \fIInstance\fR is
+copied into the value-list. In this case \fIInstance\fR may be empty, i.\ e.
+"".
+.IP "\fBInstancePrefix\fR \fIString\fR" 4
+.IX Item "InstancePrefix String"
+If \fBTable\fR is set to \fItrue\fR, you may feel the need to add something to the
+instance of the files. If set, \fIString\fR is prepended to the instance as
+determined by querying the agent. When \fBTable\fR is set to \fIfalse\fR this option
+has no effect.
+.Sp
+The \f(CW\*(C`UPS\-MIB\*(C'\fR is an example where you need this setting: It has voltages of
+the inlets, outlets and the battery of an \s-1UPS.\s0 However, it doesn't provide a
+descriptive column for these voltages. In this case having 1, 2,\ ... as
+instances is not enough, because the inlet voltages and outlet voltages may
+both have the subids 1, 2,\ ... You can use this setting to distinguish
+between the different voltages.
+.IP "\fBValues\fR \fI\s-1OID\s0\fR [\fI\s-1OID\s0\fR ...]" 4
+.IX Item "Values OID [OID ...]"
+Configures the values to be queried from the \s-1SNMP\s0 host. The meaning slightly
+changes with the \fBTable\fR setting. \fIvariables\fR\|(5) from the \s-1SNMP\s0 distribution
+describes the format of OIDs.
+.Sp
+If \fBTable\fR is set to \fItrue\fR, each \fI\s-1OID\s0\fR must be the prefix of all the
+values to query, e.\ g. \f(CW\*(C`IF\-MIB::ifInOctets\*(C'\fR for all the counters of
+incoming traffic. This subtree is walked (using \f(CW\*(C`GETNEXT\*(C'\fR) until a value from
+outside the subtree is returned.
+.Sp
+If \fBTable\fR is set to \fIfalse\fR, each \fI\s-1OID\s0\fR must be the \s-1OID\s0 of exactly one
+value, e.\ g. \f(CW\*(C`IF\-MIB::ifInOctets.3\*(C'\fR for the third counter of incoming
+traffic.
+.IP "\fBScale\fR \fIValue\fR" 4
+.IX Item "Scale Value"
+The gauge-values returned by the SNMP-agent are multiplied by \fIValue\fR.  This
+is useful when values are transferred as a fixed point real number. For example,
+thermometers may transfer \fB243\fR but actually mean \fB24.3\fR, so you can specify
+a scale value of \fB0.1\fR to correct this. The default value is, of course,
+\&\fB1.0\fR.
+.Sp
+This value is not applied to counter-values.
+.IP "\fBShift\fR \fIValue\fR" 4
+.IX Item "Shift Value"
+\&\fIValue\fR is added to gauge-values returned by the SNMP-agent after they have
+been multiplied by any \fBScale\fR value. If, for example, a thermometer returns
+degrees Kelvin you could specify a shift of \fB273.15\fR here to store values in
+degrees Celsius. The default value is, of course, \fB0.0\fR.
+.Sp
+This value is not applied to counter-values.
+.IP "\fBIgnore\fR \fIValue\fR [, \fIValue\fR ...]" 4
+.IX Item "Ignore Value [, Value ...]"
+The ignore values allows to ignore Instances based on their name and the patterns
+specified by the various values you've entered. The match is a glob-type shell
+matching.
+.IP "\fBInvertMatch\fR \fItrue|false(default)\fR" 4
+.IX Item "InvertMatch true|false(default)"
+The invertmatch value should be use in combination of the Ignore option.
+It changes the behaviour of the Ignore option, from a blacklist behaviour
+when InvertMatch is set to false, to a whitelist when specified to true.
+.SS "The Host block"
+.IX Subsection "The Host block"
+The \fBHost\fR block defines which hosts to query, which \s-1SNMP\s0 community and
+version to use and which of the defined \fBData\fR to query.
+.PP
+The argument passed to the \fBHost\fR block is used as the hostname in the data
+stored by collectd.
+.IP "\fBAddress\fR \fIIP-Address\fR|\fIHostname\fR" 4
+.IX Item "Address IP-Address|Hostname"
+Set the address to connect to.
+.IP "\fBVersion\fR \fB1\fR|\fB2\fR|\fB3\fR" 4
+.IX Item "Version 1|2|3"
+Set the \s-1SNMP\s0 version to use. When giving \fB2\fR version \f(CW\*(C`2c\*(C'\fR is actually used.
+.IP "\fBCommunity\fR \fICommunity\fR" 4
+.IX Item "Community Community"
+Pass \fICommunity\fR to the host. (Ignored for SNMPv3).
+.IP "\fBUsername\fR \fIUsername\fR" 4
+.IX Item "Username Username"
+Sets the \fIUsername\fR to use for SNMPv3 security.
+.IP "\fBSecurityLevel\fR \fIauthPriv\fR|\fIauthNoPriv\fR|\fInoAuthNoPriv\fR" 4

+=head1 DESCRIPTION
+
+The C<snmp plugin> queries other hosts using SNMP, the simple network
+management protocol, and translates the value it receives to collectd's
+internal format and dispatches them. Depending on the write plugins you have
+loaded they may be written to disk or submitted to another instance or
+whatever you configured.
+
+Because querying a host via SNMP may produce a timeout multiple threads are
+used to query hosts in parallel. Depending on the number of hosts between one
+and ten threads are used.
+
+=head1 CONFIGURATION
+
+Since the aim of the C<snmp plugin> is to provide a generic interface to SNMP,
+it's configuration is not trivial and may take some time.
+
+Since the C<Net-SNMP> library is used you can use all the environment variables
+that are interpreted by that package. See L<snmpcmd(1)> for more details.
+
+There are two types of blocks that can be contained in the
+C<E<lt>PluginE<nbsp>snmpE<gt>> block: B<Data> and B<Host>:
+
+=head2 The B<Data> block
+
+The B<Data> block defines a list of values or a table of values that are to be
+queried. The following options can be set:
+
+=over 4
+
+=item B<Type> I<type>
+
+collectd's type that is to be used, e.E<nbsp>g. "if_octets" for interface
+traffic or "users" for a user count. The types are read from the B<TypesDB>
+(see L<collectd.conf(5)>), so you may want to check for which types are
+defined. See L<types.db(5)> for a description of the format of this file.
+
+=item B<Table> I<true|false>
+
+Define if this is a single list of values or a table of values. The difference
+is the following:
+
+When B<Table> is set to B<false>, the OIDs given to B<Values> (see below) are
+queried using the C<GET> SNMP command (see L<snmpget(1)>) and transmitted to
+collectd. B<One> value list is dispatched and, eventually, one file will be
+written.
+
+When B<Table> is set to B<true>, the OIDs given to B<Values> (see below) are
+queried using the C<GETNEXT> SNMP command until the subtree is left. After all
+the lists (think: all columns of the table) have been read B<several> values
+sets will be dispatches and, eventually, several files will be written. If you
+configure a B<Type> (see above) which needs more than one data source (for
+example C<if_octets> which needs C<rx> and C<tx>) you will need to specify more
+than one (two, in the example case) OIDs with the B<Values> option. This has
+nothing to do with the B<Table> setting.
+
+For example, if you want to query the number of users on a system, you can use
+C<HOST-RESOURCES-MIB::hrSystemNumUsers.0>. This is one value and belongs to one
+value list, therefore B<Table> must be set to B<false>. Please note that, in
+this case, you have to include the sequence number (zero in this case) in the
+OID.
+
+Counter example: If you want to query the interface table provided by the
+C<IF-MIB>, e.E<nbsp>g. the bytes transmitted. There are potentially many
+interfaces, so you will want to set B<Table> to B<true>. Because the
+C<if_octets> type needs two values, received and transmitted bytes, you need to
+specify two OIDs in the B<Values> setting, in this case likely
+C<IF-MIB::ifHCInOctets> and C<IF-MIB::ifHCOutOctets>. But, this is because of
+the B<Type> setting, not the B<Table> setting.
+
+Since the semantic of B<Instance> and B<Values> depends on this setting you
+need to set it before setting them. Doing vice verse will result in undefined
+behavior.
+
+=item B<Instance> I<Instance>
+
+Sets the type-instance of the values that are dispatched. The meaning of this
+setting depends on whether B<Table> is set to I<true> or I<false>:
+
+If B<Table> is set to I<true>, I<Instance> is interpreted as an SNMP-prefix
+that will return a list of values. Those values are then used as the actual
+type-instance. An example would be the C<IF-MIB::ifDescr> subtree.
+L<variables(5)> from the SNMP distribution describes the format of OIDs.
+
+If B<Table> is set to I<true> and B<Instance> is omitted, then "SUBID" will be
+used as the instance.
+
+If B<Table> is set to I<false> the actual string configured for I<Instance> is
+copied into the value-list. In this case I<Instance> may be empty, i.E<nbsp>e.
+"".
+
+=item B<InstancePrefix> I<String>
+
+If B<Table> is set to I<true>, you may feel the need to add something to the
+instance of the files. If set, I<String> is prepended to the instance as
+determined by querying the agent. When B<Table> is set to I<false> this option
+has no effect.
+
+The C<UPS-MIB> is an example where you need this setting: It has voltages of
+the inlets, outlets and the battery of an UPS. However, it doesn't provide a
+descriptive column for these voltages. In this case having 1, 2,E<nbsp>... as
+instances is not enough, because the inlet voltages and outlet voltages may
+both have the subids 1, 2,E<nbsp>... You can use this setting to distinguish
+between the different voltages.
+
+=item B<Values> I<OID> [I<OID> ...]
+
+Configures the values to be queried from the SNMP host. The meaning slightly
+changes with the B<Table> setting. L<variables(5)> from the SNMP distribution
+describes the format of OIDs.
+
+If B<Table> is set to I<true>, each I<OID> must be the prefix of all the
+values to query, e.E<nbsp>g. C<IF-MIB::ifInOctets> for all the counters of
+incoming traffic. This subtree is walked (using C<GETNEXT>) until a value from
+outside the subtree is returned.
+
+If B<Table> is set to I<false>, each I<OID> must be the OID of exactly one
+value, e.E<nbsp>g. C<IF-MIB::ifInOctets.3> for the third counter of incoming
+traffic.
+
+=item B<Scale> I<Value>
+
+The gauge-values returned by the SNMP-agent are multiplied by I<Value>.  This
+is useful when values are transferred as a fixed point real number. For example,
+thermometers may transfer B<243> but actually mean B<24.3>, so you can specify
+a scale value of B<0.1> to correct this. The default value is, of course,
+B<1.0>.
+
+This value is not applied to counter-values.
+
+=item B<Shift> I<Value>
+
+I<Value> is added to gauge-values returned by the SNMP-agent after they have
+been multiplied by any B<Scale> value. If, for example, a thermometer returns
+degrees Kelvin you could specify a shift of B<273.15> here to store values in
+degrees Celsius. The default value is, of course, B<0.0>.
+
+This value is not applied to counter-values.
+
+=item B<Ignore> I<Value> [, I<Value> ...]
+
+The ignore values allows to ignore Instances based on their name and the patterns
+specified by the various values you've entered. The match is a glob-type shell
+matching.
+
+=item B<InvertMatch> I<true|false(default)>
+
+The invertmatch value should be use in combination of the Ignore option.
+It changes the behaviour of the Ignore option, from a blacklist behaviour
+when InvertMatch is set to false, to a whitelist when specified to true.
+
+=back
+
+=head2 The Host block
+
+The B<Host> block defines which hosts to query, which SNMP community and
+version to use and which of the defined B<Data> to query.
+
+The argument passed to the B<Host> block is used as the hostname in the data
+stored by collectd.
+
+=over 4
+
+=item B<Address> I<IP-Address>|I<Hostname>
+
+Set the address to connect to.
+
+=item B<Version> B<1>|B<2>|B<3>
+
+Set the SNMP version to use. When giving B<2> version C<2c> is actually used.
+
+=item B<Community> I<Community>
+
+Pass I<Community> to the host. (Ignored for SNMPv3).
+
+=item B<Username> I<Username>
+
+Sets the I<Username> to use for SNMPv3 security.

+
+Selects the security level for SNMPv3 security.
+
+=item B<Context> I<Context>
+
+Sets the I<Context> for SNMPv3 security.
+
+=item B<AuthProtocol> I<MD5>|I<SHA>
+
+Selects the authentication protocol for SNMPv3 security.

+=item B<AuthPassphrase> I<Passphrase>
+
+Sets the authentication passphrase for SNMPv3 security.

+
+Selects the privacy (encryption) protocol for SNMPv3 security.

+
+Defines which values to collect. I<Data> refers to one of the B<Data> block
+above. Since the config file is read top-down you need to define the data

+
+=item B<Interval> I<Seconds>
+
+Collect data from this host every I<Seconds> seconds. This option is meant for

+Starting with version \f(CW4.3.0\fR \fIcollectd\fR has support for \fBmonitoring\fR. By
+that we mean that the values are not only stored or sent somewhere, but that
+they are judged and, if a problem is recognized, acted upon. The only action
+the \fIThreshold plugin\fR takes itself is to generate and dispatch a
+\&\fInotification\fR. Other plugins can register to receive notifications and
+perform appropriate further actions.
+.PP
+Since systems and what you expect them to do differ a lot, you can configure
+\&\fIthresholds\fR for your values freely. This gives you a lot of flexibility but
+also a lot of responsibility.
+.PP
+Every time a value is out of range, a notification is dispatched. This means
+that the idle percentage of your \s-1CPU\s0 needs to be less then the configured
+threshold only once for a notification to be generated. There's no such thing
+as a moving average or similar \- at least not now.
+.PP
+Also, all values that match a threshold are considered to be relevant or
+\&\*(L"interesting\*(R". As a consequence collectd will issue a notification if they are
+not received for \fBTimeout\fR iterations. The \fBTimeout\fR configuration option is
+explained in section \*(L"\s-1GLOBAL\s0 \s-1OPTIONS\s0\*(R" in \fIcollectd.conf\fR\|(5). If, for example,
+\&\fBTimeout\fR is set to \*(L"2\*(R" (the default) and some hosts sends it's \s-1CPU\s0 statistics
+to the server every 60 seconds, a notification will be dispatched after about
+120 seconds. It may take a little longer because the timeout is checked only
+once each \fBInterval\fR on the server.
+.PP
+When a value comes within range again or is received after it was missing, an
+\&\*(L"OKAY-notification\*(R" is dispatched.

+There are basically two types of configuration statements: The \f(CW\*(C`Host\*(C'\fR,
+\&\f(CW\*(C`Plugin\*(C'\fR, and \f(CW\*(C`Type\*(C'\fR blocks select the value for which a threshold should be
+configured. The \f(CW\*(C`Plugin\*(C'\fR and \f(CW\*(C`Type\*(C'\fR blocks may be specified further using the
+\&\f(CW\*(C`Instance\*(C'\fR option. You can combine the block by nesting the blocks, though
+they must be nested in the above order, i.e. \f(CW\*(C`Host\*(C'\fR may contain either
+\&\f(CW\*(C`Plugin\*(C'\fR and \f(CW\*(C`Type\*(C'\fR blocks, \f(CW\*(C`Plugin\*(C'\fR may only contain \f(CW\*(C`Type\*(C'\fR blocks and

+value the most specific block is used.

+The other statements specify the threshold to configure. They \fBmust\fR be

+\&\f(CW\*(C`midterm\*(C'\fR, and \f(CW\*(C`longterm\*(C'\fR.
+.Sp
+Normally, all data sources are checked against a configured threshold. If this

+If set to \fBtrue\fR the range of acceptable values is inverted, i.e. values

+that the threshold must be match before dispatch any notification.
+.IP "\fBHysteresis\fR \fIValue\fR" 4
+.IX Item "Hysteresis Value"
+Sets the hysteresis value for threshold. The hysteresis is a method to prevent

+If set to \fBtrue\fR (the default), a notification with severity \f(CW\*(C`FAILURE\*(C'\fR will
+be created when a matching value list is no longer updated and purged from the

+and the global \fBTimeout\fR setting. See the \fBInterval\fR and \fBTimeout\fR settings

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \f(CW\*(C`unixsock plugin\*(C'\fR opens an UNIX-socket over which one can interact with
+the daemon. This can be used to use the values collected by collectd in other
+applications, such as monitoring solutions, or submit externally collected
+values to collectd.
+.PP
+For example, this plugin is used by \fIcollectd\-nagios\fR\|(1) to check if some
+value is in a certain range and exit with a Nagios-compatible exit code.
+.SH "COMMANDS"
+.IX Header "COMMANDS"
+Upon start the \f(CW\*(C`unixsock plugin\*(C'\fR opens a UNIX-socket and waits for
+connections. Once a connection is established the client can send commands to
+the daemon which it will answer, if it understand them.
+.PP
+In general the plugin answers with a status line of the following form:
+.PP
+\&\fIStatus\fR \fIMessage\fR
+.PP
+If \fIStatus\fR is greater than or equal to zero the message indicates success,
+if \fIStatus\fR is less than zero the message indicates failure. \fIMessage\fR is a
+human-readable string that further describes the return value.
+.PP
+On success, \fIStatus\fR furthermore indicates the number of subsequent lines of
+output (not including the status line). Each such lines usually contains a
+single return value. See the description of each command for details.
+.PP
+The following commands are implemented:
+.IP "\fB\s-1GETVAL\s0\fR \fIIdentifier\fR" 4
+.IX Item "GETVAL Identifier"
+If the value identified by \fIIdentifier\fR (see below) is found the complete

+on its own line (the number of lines is indicated by the status line \- see
+above). Each name-value-pair is of the form \fIname\fR\fB=\fR\fIvalue\fR.
+Counter-values are converted to a rate, e.\ g. bytes per second.
+Undefined values are returned as \fBNaN\fR.

+Example:

+Submits a notification to the daemon which will then dispatch it to all plugins
+which have registered for receiving notifications. 
+
+The B<PUTNOTIF> command is followed by a list of options which further describe
+the notification. The B<message> option is special in that it will consume the
+rest of the line as its value. The B<message>, B<severity>, and B<time> options
+are mandatory.
+
+Valid options are:
+
+=over 4
+
+=item B<message=>I<Message> (B<REQUIRED>)
+
+Sets the message of the notification. This is the message that will be made
+accessible to the user, so it should contain some useful information. As with
+all options: If the message includes spaces, it must be quoted with double
+quotes. This option is mandatory.
+
+=item B<severity=failure>|B<warning>|B<okay> (B<REQUIRED>)
+
+Sets the severity of the notification. This option is mandatory.
+
+=item B<time=>I<Time> (B<REQUIRED>)
+
+Sets the time of the notification. The time is given as "epoch", i.E<nbsp>e. as
+seconds since January 1st, 1970, 00:00:00. This option is mandatory.
+
+=item B<host=>I<Hostname>
+
+=item B<plugin=>I<Plugin>
+
+=item B<plugin_instance=>I<Plugin-Instance>
+
+=item B<type=>I<Type>
+
+=item B<type_instance=>I<Type-Instance>
+
+These "associative" options establish a relation between this notification and
+collected performance data. This connection is purely informal, i.E<nbsp>e. the
+daemon itself doesn't do anything with this information. However, websites or
+GUIs may use this information to place notifications near the affected graph or
+table. All the options are optional, but B<plugin_instance> without B<plugin>
+or B<type_instance> without B<type> doesn't make much sense and should be
+avoided.
+
+=item B<type:key=>I<value>
+
+Sets user defined meta information. The B<type> key is a single character
+defining the type of the meta information.
+
+The current supported types are:
+
+=over 8
+
+=item B<s> A string passed as-is.
+
+=back
+
+=back
+
+Please note that this is the same format as used in the B<exec plugin>, see
+L<collectd-exec(5)>.
+
+Example:
+  -> | PUTNOTIF type=temperature severity=warning time=1201094702 message=The roof is on fire!
+  <- | 0 Success
+
+=item B<FLUSH> [B<timeout=>I<Timeout>] [B<plugin=>I<Plugin> [...]] [B<identifier=>I<Ident> [...]]
+
+Flushes all cached data older than I<Timeout> seconds. If no timeout has been
+specified, it defaults to -1 which causes all data to be flushed.
+
+If the B<plugin> option has been specified, only the I<Plugin> plugin will be
+flushed. You can have multiple B<plugin> options to flush multiple plugins in
+one go. If the B<plugin> option is not given all plugins providing a flush
+callback will be flushed.
+
+If the B<identifier> option is given only the specified values will be flushed.
+This is meant to be used by graphing or displaying frontends which want to have
+the latest values for a specific graph. Again, you can specify the
+B<identifier> option multiple times to flush several values. If this option is
+not specified at all, all values will be flushed.
+
+Example:
+  -> | FLUSH plugin=rrdtool identifier=localhost/df/df-root identifier=localhost/df/df-var
+  <- | 0 Done: 2 successful, 0 errors
+
+=back
+
+=head2 Identifiers
+
+Value or value-lists are identified in a uniform fashion:
+
+I<Hostname>/I<Plugin>/I<Type>
+
+Where I<Plugin> and I<Type> are both either of type "I<Name>" or
+"I<Name>-I<Instance>". If the identifier includes spaces, it must be quoted
+using double quotes. This sounds more complicated than it is, so here are
+some examples:
+
+  myhost/cpu-0/cpu-user
+  myhost/load/load
+  myhost/memory/memory-used
+  myhost/disk-sda/disk_octets
+  "myups/snmp/temperature-Outlet 1"
+
+=head1 ABSTRACTION LAYER
+
+B<collectd> ships the Perl-Module L<Collectd::Unixsock> which
+provides an abstraction layer over the actual socket connection. It can be
+found in the directory F<bindings/perl/> in the source distribution or
+(usually) somewhere near F</usr/share/perl5/> if you're using a package. If
+you want to use Perl to communicate with the daemon, you're encouraged to use
+and expand this module.

+.SH "NAME"
+collectd \- System statistics collection daemon
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+collectd \fI[options]\fR
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+collectd is a daemon that receives system statistics and makes them available
+in a number of ways. The main daemon itself doesn't have any real functionality
+apart from loading, querying and submitting to plugins. For a description of
+available plugins please see \*(L"\s-1PLUGINS\*(R"\s0 below.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+Most of collectd's configuration is done using using a configfile. See
+\&\fIcollectd.conf\fR\|(5) for an in-depth description of all options.
+.IP "\fB\-C\fR \fI<config\-file>\fR" 4
+.IX Item "-C <config-file>"
+Specify an alternative config file. This is the place to go when you wish to
+change \fBcollectd\fR's behavior. The path may be relative to the current working
+directory.
+.IP "\fB\-t\fR" 4
+.IX Item "-t"
+Test the configuration only. The program immediately exits after parsing the
+config file. A return code not equal to zero indicates an error.
+.IP "\fB\-T\fR" 4
+.IX Item "-T"
+Test the plugin read callbacks only. The program immediately exits after invoking
+the read callbacks once. A return code not equal to zero indicates an error.
+.IP "\fB\-P\fR \fI<pid\-file>\fR" 4
+.IX Item "-P <pid-file>"
+Specify an alternative pid file. This overwrites any settings in the config 
+file. This is thought for init-scripts that require the PID-file in a certain
+directory to work correctly. For everyday-usage use the \fBPIDFile\fR
+config-option.
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Don't fork to the background. \fIcollectd\fR will also \fBnot\fR close standard file
+descriptors, detach from the session nor write a pid file. This is mainly
+thought for 'supervising' init replacements such as \fIrunit\fR. If using
+\&\fIupstart\fR or \fIsystemd\fR though, starting with version 5.5.0 \fIcollectd\fR is
+able to notify these two init replacements, and \fBdoes\fR require forking to the
+background for process supervision. The \fIcontrib/\fR directory has sample
+\&\fIupstart\fR and \fIsystemd\fR configuration files.
+.IP "\fB\-h\fR" 4
+.IX Item "-h"
+Output usage information and exit.
+.SH "PLUGINS"
+.IX Header "PLUGINS"
+As noted above, the real power of collectd lies within it's plugins. A
+(hopefully complete) list of plugins and short descriptions can be found in the
+\&\fI\s-1README\s0\fR file that is distributed with the sourcecode. If you're using a
+package it's a good bet to search somewhere near \fI/usr/share/doc/collectd\fR.
+.PP
+There are two big groups of plugins, \fBinput\fR and \fBoutput\fR plugins:
+.IP "\(bu" 4
+Input plugins are queried periodically. They somehow acquire the current value
+of whatever they where designed to work with and submit these values back to
+the daemon, i. e. they \*(L"dispatch\*(R" the values. As an example, the \f(CW\*(C`cpu plugin\*(C'\fR
+reads the current cpu-counters of time spent in the various modes (user,
+system, nice, ...) and dispatches these counters to the daemon.
+.IP "\(bu" 4
+Output plugins get the dispatched values from the daemon and does something
+with them. Common applications are writing to RRD-files, CSV-files or sending
+the data over a network link to a remote box.
+.PP
+Of course not all plugins fit neatly into one of the two above categories. The
+\&\f(CW\*(C`network plugin\*(C'\fR, for example, is able to send (i.\ e. \*(L"write\*(R") \fBand\fR
+receive (i.\ e. \*(L"dispatch\*(R") values. Also, it opens a socket upon
+initialization and dispatches the values when it receives them and isn't
+triggered at the same time the input plugins are being read. You can think of
+the network receive part as working asynchronous if it helps.
+.PP
+In addition to the above, there are \*(L"logging plugins\*(R". Right now those are the
+\&\f(CW\*(C`logfile plugin\*(C'\fR and the \f(CW\*(C`syslog plugin\*(C'\fR. With these plugins collectd can
+provide information about issues and significant situations to the user.
+Several loglevels let you suppress uninteresting messages.
+.PP
+Starting with version \f(CW4.3.0\fR collectd has support for \fBmonitoring\fR. This is
+done by checking thresholds defined by the user. If a value is out of range, a
+notification will be dispatched to \*(L"notification plugins\*(R". See
+\&\fIcollectd.conf\fR\|(5) for more detailed information about threshold checking.
+.PP
+Please note that some plugins, that provide other means of communicating with
+the daemon, have manpages of their own to describe their functionality in more
+detail. In particular those are \fIcollectd\-email\fR\|(5), \fIcollectd\-exec\fR\|(5),
+\&\fIcollectd\-perl\fR\|(5), \fIcollectd\-snmp\fR\|(5), and \fIcollectd\-unixsock\fR\|(5)
+.SH "SIGNALS"
+.IX Header "SIGNALS"
+\&\fBcollectd\fR accepts the following signals:
+.IP "\fB\s-1SIGINT\s0\fR, \fB\s-1SIGTERM\s0\fR" 4
+.IX Item "SIGINT, SIGTERM"
+These signals cause \fBcollectd\fR to shut down all plugins and terminate.
+.IP "\fB\s-1SIGUSR1\s0\fR" 4
+.IX Item "SIGUSR1"
+This signal causes \fBcollectd\fR to signal all plugins to flush data from
+internal caches. E.\ g. the \f(CW\*(C`rrdtool plugin\*(C'\fR will write all pending data
+to the \s-1RRD\s0 files. This is the same as using the \f(CW\*(C`FLUSH \-1\*(C'\fR command of the
+\&\f(CW\*(C`unixsock plugin\*(C'\fR.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+This config file controls how the system statistics collection daemon
+\&\fBcollectd\fR behaves. The most significant option is \fBLoadPlugin\fR, which
+controls which plugins to load. These plugins ultimately define collectd's
+behavior. If the \fBAutoLoadPlugin\fR option has been enabled, the explicit
+\&\fBLoadPlugin\fR lines may be omitted for all plugins with a configuration block,
+i.e. a \f(CW\*(C`<Plugin\ ...>\*(C'\fR block.
+.PP
+The syntax of this config file is similar to the config file of the famous
+\&\fIApache\fR webserver. Each line contains either an option (a key and a list of
+one or more values) or a section-start or \-end. Empty lines and everything
+after a non-quoted hash-symbol (\f(CW\*(C`#\*(C'\fR) is ignored. \fIKeys\fR are unquoted
+strings, consisting only of alphanumeric characters and the underscore (\f(CW\*(C`_\*(C'\fR)
+character. Keys are handled case insensitive by \fIcollectd\fR itself and all
+plugins included with it. \fIValues\fR can either be an \fIunquoted string\fR, a
+\&\fIquoted string\fR (enclosed in double-quotes) a \fInumber\fR or a \fIboolean\fR
+expression. \fIUnquoted strings\fR consist of only alphanumeric characters and
+underscores (\f(CW\*(C`_\*(C'\fR) and do not need to be quoted. \fIQuoted strings\fR are
+enclosed in double quotes (\f(CW\*(C`"\*(C'\fR). You can use the backslash character (\f(CW\*(C`\e\*(C'\fR)
+to include double quotes as part of the string. \fINumbers\fR can be specified in
+decimal and floating point format (using a dot \f(CW\*(C`.\*(C'\fR as decimal separator),
+hexadecimal when using the \f(CW\*(C`0x\*(C'\fR prefix and octal with a leading zero (\f(CW0\fR).
+\&\fIBoolean\fR values are either \fBtrue\fR or \fBfalse\fR.
+.PP
+Lines may be wrapped by using \f(CW\*(C`\e\*(C'\fR as the last character before the newline.
+This allows long lines to be split into multiple lines. Quoted strings may be
+wrapped as well. However, those are treated special in that whitespace at the
+beginning of the following lines will be ignored, which allows for nicely
+indenting the wrapped lines.
+.PP
+The configuration is read and processed in order, i.e. from top to bottom. So
+the plugins are loaded in the order listed in this config file. It is a good
+idea to load any logging plugins first in order to catch messages from plugins
+during configuration. Also, unless \fBAutoLoadPlugin\fR is enabled, the
+\&\fBLoadPlugin\fR option \fImust\fR occur \fIbefore\fR the appropriate
+\&\f(CW\*(C`<\f(CBPlugin\f(CW ...>\*(C'\fR block.

+Loads the plugin \fIPlugin\fR. This is required to load plugins, unless the

+\&\fIcollectd\fR will be mostly useless.
+.Sp
+Only the first \fBLoadPlugin\fR statement or block for a given plugin name has any
+effect. This is useful when you want to split up the configuration into smaller
+files and want each file to be \*(L"self contained\*(R", i.e. it contains a \fBPlugin\fR
+block \fIand\fR then appropriate \fBLoadPlugin\fR statement. The downside is that if
+you have multiple conflicting \fBLoadPlugin\fR blocks, e.g. when they specify
+different intervals, only one of them (the first one encountered) will take
+effect and all others will be silently ignored.
+.Sp
+\&\fBLoadPlugin\fR may either be a simple configuration \fIstatement\fR or a \fIblock\fR
+with additional options, affecting the behavior of \fBLoadPlugin\fR. A simple
+statement looks like this:
+.Sp

+If enabled, collectd will export all global symbols of the plugin (and of all
+libraries loaded as dependencies of the plugin) and, thus, makes those symbols
+available for resolving unresolved symbols in subsequently loaded plugins if
+that is supported by your system.
+.Sp
+This is useful (or possibly even required), e.g., when loading a plugin that
+embeds some scripting language into the daemon (e.g. the \fIPerl\fR and
+\&\fIPython plugins\fR). Scripting languages usually provide means to load
+extensions written in C. Those extensions require symbols provided by the
+interpreter, which is loaded as a dependency of the respective collectd plugin.
+See the documentation of those plugins (e.g., \fIcollectd\-perl\fR\|(5) or
+\&\fIcollectd\-python\fR\|(5)) for details.
+.Sp
+By default, this is disabled. As a special exception, if the plugin name is
+either \f(CW\*(C`perl\*(C'\fR or \f(CW\*(C`python\*(C'\fR, the default is changed to enabled in order to keep

+handling callback for this plugin has been registered, a warning is logged and
+the block is ignored.
+.Sp
+When set to \fBtrue\fR, explicit \fBLoadPlugin\fR statements are not required. Each

+Metrics are read by the \fIread threads\fR and then put into a queue to be handled

+running into memory issues in such a case, you can limit the size of this
+queue.
+.Sp
+By default, there is no limit and memory may grow indefinitely. This is most
+likely not an issue for clients, i.e. instances that only handle the local
+metrics. For servers it is recommended to set this to a non-zero value, though.
+.Sp
+You can set the limits using \fBWriteQueueLimitHigh\fR and \fBWriteQueueLimitLow\fR.

+.PP
+To select all the affected values for our example, set \f(CW\*(C`Plugin cpu\*(C'\fR and

+wondering about the name. You can configure how each column is to be
+interpreted and the plugin will generate one or more data sets from each row
+returned according to these rules.
+.PP
+Because the plugin is very generic, the configuration is a little more complex
+than those of other plugins. It usually looks something like this:
+.PP
+.Vb 10

+.Ve
+.PP
+The configuration above defines one query with one result and one database. The
+query is then linked to the database with the \fBQuery\fR option \fIwithin\fR the
+\&\fB<Database>\fR block. You can have any number of queries and databases
+and you can also use the \fBInclude\fR statement to split up the configuration
+file in multiple, smaller files. However, the \fB<Query>\fR block \fImust\fR

+.PP
+The following is a complete list of options:
+.PP
+\fI\f(BIQuery\fI blocks\fR
+.IX Subsection "Query blocks"
+.PP
+Query blocks define \fI\s-1SQL\s0\fR statements and how the returned data should be
+interpreted. They are identified by the name that is given in the opening line
+of the block. Thus the name needs to be unique. Other than that, the name is
+not used in collectd.
+.PP
+In each \fBQuery\fR block, there is one or more \fBResult\fR blocks. \fBResult\fR blocks
+define which column holds which value or instance information. You can use
+multiple \fBResult\fR blocks to create multiple values from one returned row. This
+is especially useful, when queries take a long time and sending almost the same
+query again and again is not desirable.
+.PP
+Example:
+.PP
+.Vb 10
+\&  <Query "environment">
+\&    Statement "select station, temperature, humidity from environment"
+\&    <Result>
+\&      Type "temperature"

+.Ve
+.PP
+The following options are accepted:
+.IP "\fBStatement\fR \fI\s-1SQL\s0\fR" 4
+.IX Item "Statement SQL"
+Sets the statement that should be executed on the server. This is \fBnot\fR
+interpreted by collectd, but simply passed to the database server. Therefore,
+the \s-1SQL\s0 dialect that's used depends on the server collectd is connected to.
+.Sp
+The query has to return at least two columns, one for the instance and one
+value. You cannot omit the instance, even if the statement is guaranteed to
+always return exactly one line. In that case, you can usually specify something
+like this:
+.Sp
+.Vb 1
+\&  Statement "SELECT \e"instance\e", COUNT(*) AS value FROM table"
+.Ve
+.Sp
+(That works with MySQL but may not be valid \s-1SQL\s0 according to the spec. If you
+use a more strict database server, you may have to select from a dummy table or
+something.)
+.Sp
+Please note that some databases, for example \fBOracle\fR, will fail if you
+include a semicolon at the end of the statement.
+.IP "\fBMinVersion\fR \fIVersion\fR" 4
+.IX Item "MinVersion Version"
+.PD 0
+.IP "\fBMaxVersion\fR \fIValue\fR" 4
+.IX Item "MaxVersion Value"
+.PD
+Only use this query for the specified database version. You can use these
+options to provide multiple queries with the same name but with a slightly
+different syntax. The plugin will use only those queries, where the specified
+minimum and maximum versions fit the version of the database in use.
+.Sp
+The database version is determined by \f(CW\*(C`dbi_conn_get_engine_version\*(C'\fR, see the
+libdbi documentation <http://libdbi.sourceforge.net/docs/programmers-guide/reference-conn.html#DBI-CONN-GET-ENGINE-VERSION>
+for details. Basically, each part of the version is assumed to be in the range
+from \fB00\fR to \fB99\fR and all dots are removed. So version \*(L"4.1.2\*(R" becomes
+\&\*(L"40102\*(R", version \*(L"5.0.42\*(R" becomes \*(L"50042\*(R".
+.Sp
+\&\fBWarning:\fR The plugin will use \fBall\fR matching queries, so if you specify
+multiple queries with the same name and \fBoverlapping\fR ranges, weird stuff will
+happen. Don't to it! A valid example would be something along these lines:
+.Sp
+.Vb 8
+\&  MinVersion 40000
+\&  MaxVersion 49999
+\&  ...
+\&  MinVersion 50000
+\&  MaxVersion 50099
+\&  ...
+\&  MinVersion 50100
+\&  # No maximum
+.Ve
+.Sp
+In the above example, there are three ranges that don't overlap. The last one
+goes from version \*(L"5.1.0\*(R" to infinity, meaning \*(L"all later versions\*(R". Versions
+before \*(L"4.0.0\*(R" are not specified.

+.IX Item "Type Type"
+The \fBtype\fR that's used for each line returned. See \fItypes.db\fR\|(5) for more
+details on how types are defined. In short: A type is a predefined layout of
+data and the number of values and type of values has to match the type
+definition.
+.Sp
+If you specify \*(L"temperature\*(R" here, you need exactly one gauge column. If you
+specify \*(L"if_octets\*(R", you will need two counter columns. See the \fBValuesFrom\fR
+setting below.
+.Sp
+There must be exactly one \fBType\fR option inside each \fBResult\fR block.
+.IP "\fBInstancePrefix\fR \fIprefix\fR" 4
+.IX Item "InstancePrefix prefix"
+Prepends \fIprefix\fR to the type instance. If \fBInstancesFrom\fR (see below) is not
+given, the string is simply copied. If \fBInstancesFrom\fR is given, \fIprefix\fR and
+all strings returned in the appropriate columns are concatenated together,
+separated by dashes \fI(\*(L"\-\*(R")\fR.
+.IP "\fBInstancesFrom\fR \fIcolumn0\fR [\fIcolumn1\fR ...]" 4
+.IX Item "InstancesFrom column0 [column1 ...]"
+Specifies the columns whose values will be used to create the \*(L"type-instance\*(R"
+for each row. If you specify more than one column, the value of all columns
+will be joined together with dashes \fI(\*(L"\-\*(R")\fR as separation characters.
+.Sp
+The plugin itself does not check whether or not all built instances are
+different. It's your responsibility to assure that each is unique. This is
+especially true, if you do not specify \fBInstancesFrom\fR: \fBYou\fR have to make
+sure that only one row is returned in this case.
+.Sp
+If neither \fBInstancePrefix\fR nor \fBInstancesFrom\fR is given, the type-instance
+will be empty.
+.IP "\fBValuesFrom\fR \fIcolumn0\fR [\fIcolumn1\fR ...]" 4
+.IX Item "ValuesFrom column0 [column1 ...]"
+Names the columns whose content is used as the actual data for the data sets
+that are dispatched to the daemon. How many such columns you need is determined
+by the \fBType\fR setting above. If you specify too many or not enough columns,
+the plugin will complain about that and no data will be submitted to the
+daemon.
+.Sp
+The actual data type in the columns is not that important. The plugin will
+automatically cast the values to the right type if it know how to do that. So
+it should be able to handle integer an floating point types, as well as strings
+(if they include a number at the beginning).
+.Sp
+There must be at least one \fBValuesFrom\fR option inside each \fBResult\fR block.
+.IP "\fBMetadataFrom\fR [\fIcolumn0\fR \fIcolumn1\fR ...]" 4
+.IX Item "MetadataFrom [column0 column1 ...]"

+The actual data type in the columns is not that important. The plugin will

+.PP
+\fI\f(BIDatabase\fI blocks\fR
+.IX Subsection "Database blocks"
+.PP
+Database blocks define a connection to a database and which queries should be
+sent to that database. Since the used \*(L"dbi\*(R" library can handle a wide variety
+of databases, the configuration is very generic. If in doubt, refer to libdbi's
+documentation\ \- we stick as close to the terminology used there.
+.PP
+Each database needs a \*(L"name\*(R" as string argument in the starting tag of the
+block. This name will be used as \*(L"PluginInstance\*(R" in the values submitted to
+the daemon. Other than that, that name is not used.
+.IP "\fBDriver\fR \fIDriver\fR" 4
+.IX Item "Driver Driver"
+Specifies the driver to use to connect to the database. In many cases those
+drivers are named after the database they can connect to, but this is not a
+technical necessity. These drivers are sometimes referred to as \*(L"\s-1DBD\*(R",
+\&\s0\fBD\fRata\fBB\fRase \fBD\fRriver, and some distributions ship them in separate
+packages. Drivers for the \*(L"dbi\*(R" library are developed by the \fBlibdbi-drivers\fR
+project at <http://libdbi\-drivers.sourceforge.net/>.
+.Sp
+You need to give the driver name as expected by the \*(L"dbi\*(R" library here. You
+should be able to find that in the documentation for each driver. If you
+mistype the driver name, the plugin will dump a list of all known driver names
+to the log.
+.IP "\fBDriverOption\fR \fIKey\fR \fIValue\fR" 4
+.IX Item "DriverOption Key Value"
+Sets driver-specific options. What option a driver supports can be found in the
+documentation for each driver, somewhere at
+<http://libdbi\-drivers.sourceforge.net/>. However, the options \*(L"host\*(R",
+\&\*(L"username\*(R", \*(L"password\*(R", and \*(L"dbname\*(R" seem to be de\ facto standards.
+.Sp
+DBDs can register two types of options: String options and numeric options. The
+plugin will use the \f(CW\*(C`dbi_conn_set_option\*(C'\fR function when the configuration
+provides a string and the \f(CW\*(C`dbi_conn_require_option_numeric\*(C'\fR function when the
+configuration provides a number. So these two lines will actually result in
+different calls being used:
+.Sp
+.Vb 2
+\&  DriverOption "Port" 1234      # numeric
+\&  DriverOption "Port" "1234"    # string
+.Ve
+.Sp
+Unfortunately, drivers are not too keen to report errors when an unknown option
+is passed to them, so invalid settings here may go unnoticed. This is not the
+plugin's fault, it will report errors if it gets them from the library\ /
+the driver. If a driver complains about an option, the plugin will dump a
+complete list of all options understood by that driver to the log. There is no
+way to programatically find out if an option expects a string or a numeric
+argument, so you will have to refer to the appropriate \s-1DBD\s0's documentation to
+find this out. Sorry.

+The example above counts the number of files in QMail's queue directories and

+QMail has not yet looked at, the \*(L"message\*(R" queue holds the messages that were
+classified into \*(L"local\*(R" and \*(L"remote\*(R".
+.PP
+As you can see, the configuration consists of one or more \f(CW\*(C`Directory\*(C'\fR blocks,
+each of which specifies a directory in which to count the files. Within those
+blocks, the following options are recognized:
+.IP "\fBInstance\fR \fIInstance\fR" 4

+Sets the plugin instance to \fIInstance\fR. That instance name must be unique, but

+Count only files of a specific age: If \fIAge\fR is greater than zero, only files
+that haven't been touched in the last \fIAge\fR seconds are counted. If \fIAge\fR is
+a negative number, this is inversed. For example, if \fB\-60\fR is specified, only
+files that have been modified in the last minute will be counted.
+.Sp
+The number can also be followed by a \*(L"multiplier\*(R" to easily specify a larger
+timespan. When given in this notation, the argument must in quoted, i.\ e.
+must be passed as string. So the \fB\-60\fR could also be written as \fB\*(L"\-1m\*(R"\fR (one
+minute). Valid multipliers are \f(CW\*(C`s\*(C'\fR (second), \f(CW\*(C`m\*(C'\fR (minute), \f(CW\*(C`h\*(C'\fR (hour), \f(CW\*(C`d\*(C'\fR
+(day), \f(CW\*(C`w\*(C'\fR (week), and \f(CW\*(C`y\*(C'\fR (year). There is no \*(L"month\*(R" multiplier. You can
+also specify fractional numbers, e.\ g. \fB\*(L"0.5d\*(R"\fR is identical to
+\&\fB\*(L"12h\*(R"\fR.
+.IP "\fBSize\fR \fISize\fR" 4
+.IX Item "Size Size"
+Count only files of a specific size. When \fISize\fR is a positive number, only
+files that are at least this big are counted. If \fISize\fR is a negative number,
+this is inversed, i.\ e. only files smaller than the absolute value of
+\&\fISize\fR are counted.
+.Sp
+As with the \fBMTime\fR option, a \*(L"multiplier\*(R" may be added. For a detailed
+description see above. Valid multipliers here are \f(CW\*(C`b\*(C'\fR (byte), \f(CW\*(C`k\*(C'\fR (kilobyte),

+of encrypted packets is ensured using \fI\s-1SHA\-1\s0\fR. When set to \fBSign\fR, only
+signed and encrypted data is accepted. When set to \fBNone\fR, all data will be
+accepted. If an \fBAuthFile\fR option was given (see below), encrypted data is

+This feature is only available if the \fInetwork\fR plugin was linked with
+\&\fIlibgcrypt\fR.
+.IP "\fBAuthFile\fR \fIFilename\fR" 4
+.IX Item "AuthFile Filename"
+Sets a file in which usernames are mapped to passwords. These passwords are
+used to verify signatures and to decrypt encrypted network packets. If
+\&\fBSecurityLevel\fR is set to \fBNone\fR, this is optional. If given, signed data is
+verified and encrypted packets are decrypted. Otherwise, signed data is
+accepted without checking the signature and encrypted data cannot be decrypted.
+For the other security levels this option is mandatory.
+.Sp
+The file format is very simple: Each line consists of a username followed by a
+colon and any number of spaces followed by the password. To demonstrate, an
+example file could look like this:
+.Sp
+.Vb 2
+\&  user0: foo
+\&  user1: bar
+.Ve
+.Sp
+Each time a packet is received, the modification time of the file is checked
+using \fIstat\fR\|(2). If the file has been changed, the contents is re-read. While
+the file is being read, it is locked using \fIfcntl\fR\|(2).
+.IP "\fBInterface\fR \fIInterface name\fR" 4
+.IX Item "Interface Interface name"
+Set the incoming interface for \s-1IP\s0 packets explicitly. This applies at least
+to IPv6 packets and if possible to IPv4. If this option is not applicable,

+.Sp
+On the server side, this limit should be set to the largest value used on

+value of 1024\ bytes to avoid problems when sending data to an older
+server.
+.IP "\fBForward\fR \fItrue|false\fR" 4
+.IX Item "Forward true|false"
+If set to \fItrue\fR, write packets that were received via the network plugin to
+the sending sockets. This should only be activated when the \fBListen\fR\- and
+\&\fBServer\fR\-statements differ. Otherwise packets may be send multiple times to
+the same multicast group. While this results in more network traffic than
+necessary it's not a huge problem since the plugin has a duplicate detection,
+so the values will not loop.
+.IP "\fBReportStats\fR \fBtrue\fR|\fBfalse\fR" 4
+.IX Item "ReportStats true|false"
+The network plugin cannot only receive and send statistics, it can also create
+statistics about itself. Collected data included the number of received and
+sent octets and packets, the length of the receive queue and the number of

+.PP
+The \f(CW\*(C`onewire\*(C'\fR plugin uses the \fBowcapi\fR library from the \fBowfs\fR project
+<http://owfs.org/> to read sensors connected via the onewire bus.
+.PP
+It can be used in two possible modes \- standard or advanced.
+.PP
+In the standard mode only temperature sensors (sensors with the family code
+\&\f(CW10\fR, \f(CW22\fR and \f(CW28\fR \- e.g. \s-1DS1820, DS18S20, DS1920\s0) can be read. If you have
+other sensors you would like to have included, please send a sort request to
+the mailing list. You can select sensors to be read or to be ignored depending
+on the option \fBIgnoreSelected\fR). When no list is provided the whole bus is
+walked and all sensors are read.
+.PP
+Hubs (the \s-1DS2409\s0 chips) are working, but read the note, why this plugin is
+experimental, below.
+.PP
+In the advanced mode you can configure any sensor to be read (only numerical
+value) using full \s-1OWFS\s0 path (e.g. \*(L"/uncached/10.F10FCA000800/temperature\*(R").
+In this mode you have to list all the sensors. Neither default bus walk nor
+\&\fBIgnoreSelected\fR are used here. Address and type (file) is extracted from
+the path automatically and should produce compatible structure with the \*(L"standard\*(R"
+mode (basically the path is expected as for example
+\&\*(L"/uncached/10.F10FCA000800/temperature\*(R" where it would extract address part
+\&\*(L"F10FCA000800\*(R" and the rest after the slash is considered the type \- here
+\&\*(L"temperature\*(R").
+There are two advantages to this mode \- you can access virtually any sensor
+(not just temperature), select whether to use cached or directly read values
+and it is slighlty faster. The downside is more complex configuration.
+.PP
+The two modes are distinguished automatically by the format of the address.
+It is not possible to mix the two modes. Once a full path is detected in any

+(and as standard addresses will fail parsing they will be ignored).
+.IP "\fBDevice\fR \fIDevice\fR" 4

+Sets the device to read the values from. This can either be a \*(L"real\*(R" hardware
+device, such as a serial port or an \s-1USB\s0 port, or the address of the
+\&\fIowserver\fR\|(1) socket, usually \fBlocalhost:4304\fR.
+.Sp
+Though the documentation claims to automatically recognize the given address
+format, with version\ 2.7p4 we had to specify the type explicitly. So

+In the standard mode selects sensors to collect or to ignore
+(depending on \fBIgnoreSelected\fR, see below). Sensors are specified without
+the family byte at the beginning, so you have to use for example \f(CW\*(C`F10FCA000800\*(C'\fR,
+and \fBnot\fR include the leading \f(CW10.\fR family byte and point.
+When no \fBSensor\fR is configured the whole Onewire bus is walked and all supported
+sensors (see above) are read.
+.Sp
+In the advanced mode the \fBSensor\fR specifies full \s-1OWFS\s0 path \- e.g.
+\&\f(CW\*(C`/uncached/10.F10FCA000800/temperature\*(C'\fR (or when cached values are \s-1OK
+\&\s0\f(CW\*(C`/10.F10FCA000800/temperature\*(C'\fR). \fBIgnoreSelected\fR is not used.

+multiple \fBSensor\fR elements).
+.IP "\fBIgnoreSelected\fR \fItrue\fR|\fIfalse\fR" 4
+.IX Item "IgnoreSelected true|false"
+If no configuration is given, the \fBonewire\fR plugin will collect data from all
+sensors found. This may not be practical, especially if sensors are added and
+removed regularly. Sometimes, however, it's easier/preferred to collect only
+specific sensors or all sensors \fIexcept\fR a few specified ones. This option
+enables you to do that: By setting \fBIgnoreSelected\fR to \fItrue\fR the effect of
+\&\fBSensor\fR is inverted: All selected interfaces are ignored and all other
+interfaces are collected.
+.Sp
+Used only in the standard mode \- see above.
+.IP "\fBInterval\fR \fISeconds\fR" 4

+.PP

+work with big setups. It works with one sensor being attached to one

+interval). We will probably add some separate thread for reading the sensors
+and some cache or something like that, but it's not done yet. We will try to
+maintain backwards compatibility in the future, but we can't promise. So in

+The \f(CW\*(C`postgresql\*(C'\fR plugin queries statistics from PostgreSQL databases. It
+keeps a persistent connection to all configured databases and tries to
+reconnect if the connection has been interrupted. A database is configured by
+specifying a \fBDatabase\fR block as described below. The default statistics are

+enabled for this plugin to work correctly. This should usually be the case by

+Documentation\fR for details.
+.PP
+By specifying custom database queries using a \fBQuery\fR block as described
+below, you may collect any data that is available from some PostgreSQL
+database. This way, you are able to access statistics of external daemons
+which are available in a PostgreSQL database or use future or special
+statistics provided by PostgreSQL without the need to upgrade your collectd
+installation.
+.PP
+Starting with version 5.2, the \f(CW\*(C`postgresql\*(C'\fR plugin supports writing data to
+PostgreSQL databases as well. This has been implemented in a generic way. You
+need to specify an \s-1SQL\s0 statement which will then be executed by collectd in
+order to write the data (see below for details). The benefit of that approach
+is that there is no fixed database layout. Rather, the layout may be optimized
+for the current setup.

+The \f(CW\*(C`rrdtool plugin\*(C'\fR calculates the number of PDPs per \s-1CDP\s0 based on the

+it writes all values for a certain RRD-file if the oldest value is older than
+(or equal to) the number of seconds specified. If some RRD-file is not updated
+anymore for some reason (the computer was shut down, the network is broken,
+etc.) some values may still be in the cache. If \fBCacheFlush\fR is set, then the
+entire cache is searched for entries older than \fBCacheTimeout\fR seconds and
+written to disk every \fISeconds\fR seconds. Since this is kind of expensive and
+does nothing under normal circumstances, this value should not be too small.
+900 seconds might be a good value, though setting this to 7200 seconds doesn't
+normally do much harm either.
+.IP "\fBCacheTimeout\fR \fISeconds\fR" 4
+.IX Item "CacheTimeout Seconds"
+If this option is set to a value greater than zero, the \f(CW\*(C`rrdtool plugin\*(C'\fR will
+save values in a cache, as described above. Writing multiple values at once
+reduces IO-operations and thus lessens the load produced by updating the files.
+The trade off is that the graphs kind of \*(L"drag behind\*(R" and that more memory is
+used.
+.IP "\fBWritesPerSecond\fR \fIUpdates\fR" 4
+.IX Item "WritesPerSecond Updates"
+When collecting many statistics with collectd and the \f(CW\*(C`rrdtool\*(C'\fR plugin, you
+will run serious performance problems. The \fBCacheFlush\fR setting and the
+internal update queue assert that collectd continues to work just fine even
+under heavy load, but the system may become very unresponsive and slow. This is
+a problem especially if you create graphs from the \s-1RRD\s0 files on the same
+machine, for example using the \f(CW\*(C`graph.cgi\*(C'\fR script included in the
+\&\f(CW\*(C`contrib/collection3/\*(C'\fR directory.
+.Sp
+This setting is designed for very large setups. Setting this option to a value
+between 25 and 80 updates per second, depending on your hardware, will leave
+the server responsive enough to draw graphs even while all the cached values
+are written to disk. Flushed values, i.\ e. values that are forced to disk
+by the \fB\s-1FLUSH\s0\fR command, are \fBnot\fR effected by this limit. They are still
+written as fast as possible, so that web frontends have up to date data when
+generating graphs.
+.Sp
+For example: If you have 100,000 \s-1RRD\s0 files and set \fBWritesPerSecond\fR to 30
+updates per second, writing all values to disk will take approximately
+56\ minutes. Together with the flushing ability that's integrated into
+\&\*(L"collection3\*(R" you'll end up with a responsive and fast system, up to date
+graphs and basically a \*(L"backup\*(R" of your values every hour.
+.IP "\fBRandomTimeout\fR \fISeconds\fR" 4
+.IX Item "RandomTimeout Seconds"
+When set, the actual timeout for each value is chosen randomly between
+\&\fICacheTimeout\fR\-\fIRandomTimeout\fR and \fICacheTimeout\fR+\fIRandomTimeout\fR. The
+intention is to avoid high load situations that appear when many values timeout
+at the same time. This is especially a problem shortly after the daemon starts,
+because all values were added to the internal cache at roughly the same time.

+Starting with version \f(CW4.3.0\fR collectd has support for \fBmonitoring\fR. By that
+we mean that the values are not only stored or sent somewhere, but that they
+are judged and, if a problem is recognized, acted upon. The only action
+collectd takes itself is to generate and dispatch a \*(L"notification\*(R". Plugins can
+register to receive notifications and perform appropriate further actions.
+.PP
+Since systems and what you expect them to do differ a lot, you can configure
+\&\fBthresholds\fR for your values freely. This gives you a lot of flexibility but
+also a lot of responsibility.
+.PP
+Every time a value is out of range a notification is dispatched. This means
+that the idle percentage of your \s-1CPU\s0 needs to be less then the configured
+threshold only once for a notification to be generated. There's no such thing
+as a moving average or similar \- at least not now.
+.PP
+Also, all values that match a threshold are considered to be relevant or
+\&\*(L"interesting\*(R". As a consequence collectd will issue a notification if they are
+not received for \fBTimeout\fR iterations. The \fBTimeout\fR configuration option is
+explained in section \*(L"\s-1GLOBAL OPTIONS\*(R"\s0. If, for example, \fBTimeout\fR is set to
+\&\*(L"2\*(R" (the default) and some hosts sends it's \s-1CPU\s0 statistics to the server every
+60 seconds, a notification will be dispatched after about 120 seconds. It may
+take a little longer because the timeout is checked only once each \fBInterval\fR
+on the server.
+.PP
+When a value comes within range again or is received after it was missing, an
+\&\*(L"OKAY-notification\*(R" is dispatched.

+This is useful when short bursts are not a problem. If, for example, 100% \s-1CPU\s0

+.SH "FILTER CONFIGURATION"
+.IX Header "FILTER CONFIGURATION"
+Starting with collectd 4.6 there is a powerful filtering infrastructure
+implemented in the daemon. The concept has mostly been copied from
+\&\fIip_tables\fR, the packet filter infrastructure for Linux. We'll use a similar
+terminology, so that users that are familiar with iptables feel right at home.
+.SS "Terminology"
+.IX Subsection "Terminology"
+The following are the terms used in the remainder of the filter configuration
+documentation. For an ASCII-art schema of the mechanism, see
+\&\*(L"General structure\*(R" below.
+.IP "\fBMatch\fR" 4
+.IX Item "Match"
+A \fImatch\fR is a criteria to select specific values. Examples are, of course, the
+name of the value or it's current value.
+.Sp
+Matches are implemented in plugins which you have to load prior to using the
+match. The name of such plugins starts with the \*(L"match_\*(R" prefix.
+.IP "\fBTarget\fR" 4
+.IX Item "Target"
+A \fItarget\fR is some action that is to be performed with data. Such actions
+could, for example, be to change part of the value's identifier or to ignore
+the value completely.
+.Sp
+Some of these targets are built into the daemon, see \*(L"Built-in targets\*(R"
+below. Other targets are implemented in plugins which you have to load prior to
+using the target. The name of such plugins starts with the \*(L"target_\*(R" prefix.
+.IP "\fBRule\fR" 4
+.IX Item "Rule"
+The combination of any number of matches and at least one target is called a
+\&\fIrule\fR. The target actions will be performed for all values for which \fBall\fR
+matches apply. If the rule does not have any matches associated with it, the
+target action will be performed for all values.
+.IP "\fBChain\fR" 4
+.IX Item "Chain"
+A \fIchain\fR is a list of rules and possibly default targets. The rules are tried
+in order and if one matches, the associated target will be called. If a value
+is handled by a rule, it depends on the target whether or not any subsequent
+rules are considered or if traversal of the chain is aborted, see
+\&\*(L"Flow control\*(R" below. After all rules have been checked, the default targets
+will be executed.

+.SS "Flow control"
+.IX Subsection "Flow control"
+There are four ways to control which way a value takes through the filter
+mechanism:
+.IP "\fBjump\fR" 4
+.IX Item "jump"
+The built-in \fBjump\fR target can be used to \*(L"call\*(R" another chain, i.\ e.
+process the value with another chain. When the called chain finishes, usually
+the next target or rule after the jump is executed.
+.IP "\fBstop\fR" 4
+.IX Item "stop"
+The stop condition, signaled for example by the built-in target \fBstop\fR, causes
+all processing of the value to be stopped immediately.
+.IP "\fBreturn\fR" 4
+.IX Item "return"
+Causes processing in the current chain to be aborted, but processing of the
+value generally will continue. This means that if the chain was called via
+\&\fBJump\fR, the next target or rule after the jump will be executed. If the chain
+was not called by another chain, control will be returned to the daemon and it
+may pass the value to another chain.
+.IP "\fBcontinue\fR" 4
+.IX Item "continue"
+Most targets will signal the \fBcontinue\fR condition, meaning that processing
+should continue normally. There is no special built-in target for this
+condition.
+.SS "Synopsis"
+.IX Subsection "Synopsis"
+The configuration reflects this structure directly:
+.PP
+.Vb 10

+.Ve
+.PP
+The above configuration example will ignore all values where the plugin field
+is \*(L"mysql\*(R", the type is \*(L"mysql_command\*(R" and the type instance begins with
+\&\*(L"show_\*(R". All other values will be sent to the \f(CW\*(C`rrdtool\*(C'\fR write plugin via the
+default target of the chain. Since this chain is run after the value has been
+added to the cache, the MySQL \f(CW\*(C`show_*\*(C'\fR command statistics will be available
+via the \f(CW\*(C`unixsock\*(C'\fR plugin.

+.Ve
+.Sp
+After the values are passed from the \*(L"read\*(R" plugins to the dispatch functions,
+the pre-cache chain is run first. The values are added to the internal cache
+afterwards. The post-cache chain is run after the values have been added to the
+cache. So why is it such a huge deal if chains are run before or after the
+values have been added to this cache?
+.Sp
+Targets that change the identifier of a value list should be executed before
+the values are added to the cache, so that the name in the cache matches the
+name that is used in the \*(L"write\*(R" plugins. The \f(CW\*(C`unixsock\*(C'\fR plugin, too, uses
+this cache to receive a list of all available values. If you change the
+identifier after the value list has been added to the cache, this may easily
+lead to confusion, but it's not forbidden of course.
+.Sp
+The cache is also used to convert counter values to rates. These rates are, for
+example, used by the \f(CW\*(C`value\*(C'\fR match (see below). If you use the rate stored in
+the cache \fBbefore\fR the new value is added, you will use the old, \fBprevious\fR
+rate. Write plugins may use this rate, too, see the \f(CW\*(C`csv\*(C'\fR plugin, for example.
+The \f(CW\*(C`unixsock\*(C'\fR plugin uses these rates too, to implement the \f(CW\*(C`GETVAL\*(C'\fR
+command.
+.Sp
+Last but not last, the \fBstop\fR target makes a difference: If the pre-cache
+chain returns the stop condition, the value will not be added to the cache and
+the post-cache chain will not be run.
+.IP "\fBChain\fR \fIName\fR" 4
+.IX Item "Chain Name"
+Adds a new chain with a certain name. This name can be used to refer to a

+Please note that when you set \fITotal\fR to two (i.\ e. you have only two
+groups), then the least significant bit of the hash value will be the \s-1XOR\s0 of
+all least significant bits in the host name. One consequence is that when you
+have two hosts, \*(L"server0.example.com\*(R" and \*(L"server1.example.com\*(R", where the host
+name differs in one digit only and the digits differ by one, those hosts will

+=head1 DESCRIPTION
+
+This config file controls how the system statistics collection daemon
+B<collectd> behaves. The most significant option is B<LoadPlugin>, which
+controls which plugins to load. These plugins ultimately define collectd's
+behavior. If the B<AutoLoadPlugin> option has been enabled, the explicit
+B<LoadPlugin> lines may be omitted for all plugins with a configuration block,
+i.e. a C<E<lt>PluginE<nbsp>...E<gt>> block.
+
+The syntax of this config file is similar to the config file of the famous
+I<Apache> webserver. Each line contains either an option (a key and a list of
+one or more values) or a section-start or -end. Empty lines and everything
+after a non-quoted hash-symbol (C<#>) is ignored. I<Keys> are unquoted
+strings, consisting only of alphanumeric characters and the underscore (C<_>)
+character. Keys are handled case insensitive by I<collectd> itself and all
+plugins included with it. I<Values> can either be an I<unquoted string>, a
+I<quoted string> (enclosed in double-quotes) a I<number> or a I<boolean>
+expression. I<Unquoted strings> consist of only alphanumeric characters and
+underscores (C<_>) and do not need to be quoted. I<Quoted strings> are
+enclosed in double quotes (C<">). You can use the backslash character (C<\>)
+to include double quotes as part of the string. I<Numbers> can be specified in
+decimal and floating point format (using a dot C<.> as decimal separator),
+hexadecimal when using the C<0x> prefix and octal with a leading zero (C<0>).
+I<Boolean> values are either B<true> or B<false>.
+
+Lines may be wrapped by using C<\> as the last character before the newline.
+This allows long lines to be split into multiple lines. Quoted strings may be
+wrapped as well. However, those are treated special in that whitespace at the
+beginning of the following lines will be ignored, which allows for nicely
+indenting the wrapped lines.
+
+The configuration is read and processed in order, i.e. from top to bottom. So
+the plugins are loaded in the order listed in this config file. It is a good
+idea to load any logging plugins first in order to catch messages from plugins
+during configuration. Also, unless B<AutoLoadPlugin> is enabled, the
+B<LoadPlugin> option I<must> occur I<before> the appropriate
+C<E<lt>B<Plugin> ...E<gt>> block.
+
+=head1 GLOBAL OPTIONS
+
+=over 4
+
+=item B<BaseDir> I<Directory>
+
+Sets the base directory. This is the directory beneath all RRD-files are
+created. Possibly more subdirectories are created. This is also the working
+directory for the daemon.
+
+=item B<LoadPlugin> I<Plugin>
+
+Loads the plugin I<Plugin>. This is required to load plugins, unless the
+B<AutoLoadPlugin> option is enabled (see below). Without any loaded plugins,
+I<collectd> will be mostly useless.
+
+Only the first B<LoadPlugin> statement or block for a given plugin name has any
+effect. This is useful when you want to split up the configuration into smaller
+files and want each file to be "self contained", i.e. it contains a B<Plugin>
+block I<and> then appropriate B<LoadPlugin> statement. The downside is that if
+you have multiple conflicting B<LoadPlugin> blocks, e.g. when they specify
+different intervals, only one of them (the first one encountered) will take
+effect and all others will be silently ignored.
+
+B<LoadPlugin> may either be a simple configuration I<statement> or a I<block>
+with additional options, affecting the behavior of B<LoadPlugin>. A simple
+statement looks like this:
+
+ LoadPlugin "cpu"
+
+Options inside a B<LoadPlugin> block can override default settings and
+influence the way plugins are loaded, e.g.:
+
+ <LoadPlugin perl>
+   Interval 60
+ </LoadPlugin>
+
+The following options are valid inside B<LoadPlugin> blocks:
+
+=over 4
+
+=item B<Globals> B<true|false>
+
+If enabled, collectd will export all global symbols of the plugin (and of all
+libraries loaded as dependencies of the plugin) and, thus, makes those symbols
+available for resolving unresolved symbols in subsequently loaded plugins if
+that is supported by your system.
+
+This is useful (or possibly even required), e.g., when loading a plugin that
+embeds some scripting language into the daemon (e.g. the I<Perl> and
+I<Python plugins>). Scripting languages usually provide means to load
+extensions written in C. Those extensions require symbols provided by the
+interpreter, which is loaded as a dependency of the respective collectd plugin.
+See the documentation of those plugins (e.g., L<collectd-perl(5)> or
+L<collectd-python(5)>) for details.
+
+By default, this is disabled. As a special exception, if the plugin name is
+either C<perl> or C<python>, the default is changed to enabled in order to keep
+the average user from ever having to deal with this low level linking stuff.
+
+=item B<Interval> I<Seconds>
+
+Sets a plugin-specific interval for collecting metrics. This overrides the
+global B<Interval> setting. If a plugin provides own support for specifying an
+interval, that setting will take precedence.
+
+=back
+
+=item B<AutoLoadPlugin> B<false>|B<true>
+
+When set to B<false> (the default), each plugin needs to be loaded explicitly,
+using the B<LoadPlugin> statement documented above. If a
+B<E<lt>PluginE<nbsp>...E<gt>> block is encountered and no configuration
+handling callback for this plugin has been registered, a warning is logged and
+the block is ignored.
+
+When set to B<true>, explicit B<LoadPlugin> statements are not required. Each
+B<E<lt>PluginE<nbsp>...E<gt>> block acts as if it was immediately preceded by a
+B<LoadPlugin> statement. B<LoadPlugin> statements are still required for
+plugins that don't provide any configuration, e.g. the I<Load plugin>.
+
+=item B<CollectInternalStats> B<false>|B<true>
+
+When set to B<true>, various statistics about the I<collectd> daemon will be
+collected, with "collectd" as the I<plugin name>. Defaults to B<false>.
+
+The "write_queue" I<plugin instance> reports the number of elements currently
+queued and the number of elements dropped off the queue by the
+B<WriteQueueLimitLow>/B<WriteQueueLimitHigh> mechanism.
+
+The "cache" I<plugin instance> reports the number of elements in the value list
+cache (the cache you can interact with using L<collectd-unixsock(5)>).
+
+=item B<Include> I<Path> [I<pattern>]
+
+If I<Path> points to a file, includes that file. If I<Path> points to a
+directory, recursively includes all files within that directory and its
+subdirectories. If the C<wordexp> function is available on your system,
+shell-like wildcards are expanded before files are included. This means you can
+use statements like the following:
+
+  Include "/etc/collectd.d/*.conf"
+
+Starting with version 5.3, this may also be a block in which further options
+affecting the behavior of B<Include> may be specified. The following option is
+currently allowed:
+
+  <Include "/etc/collectd.d">
+    Filter "*.conf"
+  </Include>
+
+=over 4
+
+=item B<Filter> I<pattern>
+
+If the C<fnmatch> function is available on your system, a shell-like wildcard
+I<pattern> may be specified to filter which files to include. This may be used
+in combination with recursively including a directory to easily be able to
+arbitrarily mix configuration files and other documents (e.g. README files).
+The given example is similar to the first example above but includes all files
+matching C<*.conf> in any subdirectory of C</etc/collectd.d>:
+
+  Include "/etc/collectd.d" "*.conf"
+
+=back
+
+If more than one files are included by a single B<Include> option, the files
+will be included in lexicographical order (as defined by the C<strcmp>
+function). Thus, you can e.E<nbsp>g. use numbered prefixes to specify the
+order in which the files are loaded.
+
+To prevent loops and shooting yourself in the foot in interesting ways the
+nesting is limited to a depth of 8E<nbsp>levels, which should be sufficient for
+most uses. Since symlinks are followed it is still possible to crash the daemon
+by looping symlinks. In our opinion significant stupidity should result in an
+appropriate amount of pain.
+
+It is no problem to have a block like C<E<lt>Plugin fooE<gt>> in more than one
+file, but you cannot include files from within blocks.
+
+=item B<PIDFile> I<File>
+
+Sets where to write the PID file to. This file is overwritten when it exists
+and deleted when the program is stopped. Some init-scripts might override this
+setting using the B<-P> command-line option.
+
+=item B<PluginDir> I<Directory>
+
+Path to the plugins (shared objects) of collectd.
+
+=item B<TypesDB> I<File> [I<File> ...]
+
+Set one or more files that contain the data-set descriptions. See
+L<types.db(5)> for a description of the format of this file.
+
+=item B<Interval> I<Seconds>
+
+Configures the interval in which to query the read plugins. Obviously smaller
+values lead to a higher system load produced by collectd, while higher values
+lead to more coarse statistics.
+
+B<Warning:> You should set this once and then never touch it again. If you do,
+I<you will have to delete all your RRD files> or know some serious RRDtool
+magic! (Assuming you're using the I<RRDtool> or I<RRDCacheD> plugin.)
+
+=item B<MaxReadInterval> I<Seconds>
+
+Read plugin doubles interval between queries after each failed attempt
+to get data.
+
+This options limits the maximum value of the interval. The default value is
+B<86400>.
+
+=item B<Timeout> I<Iterations>
+
+Consider a value list "missing" when no update has been read or received for
+I<Iterations> iterations. By default, I<collectd> considers a value list
+missing when no update has been received for twice the update interval. Since
+this setting uses iterations, the maximum allowed time without update depends
+on the I<Interval> information contained in each value list. This is used in
+the I<Threshold> configuration to dispatch notifications about missing values,
+see L<collectd-threshold(5)> for details.
+
+=item B<ReadThreads> I<Num>
+
+Number of threads to start for reading plugins. The default value is B<5>, but
+you may want to increase this if you have more than five plugins that take a
+long time to read. Mostly those are plugins that do network-IO. Setting this to
+a value higher than the number of registered read callbacks is not recommended.
+
+=item B<WriteThreads> I<Num>
+
+Number of threads to start for dispatching value lists to write plugins. The
+default value is B<5>, but you may want to increase this if you have more than
+five plugins that may take relatively long to write to.
+
+=item B<WriteQueueLimitHigh> I<HighNum>
+
+=item B<WriteQueueLimitLow> I<LowNum>
+
+Metrics are read by the I<read threads> and then put into a queue to be handled
+by the I<write threads>. If one of the I<write plugins> is slow (e.g. network
+timeouts, I/O saturation of the disk) this queue will grow. In order to avoid
+running into memory issues in such a case, you can limit the size of this
+queue.
+
+By default, there is no limit and memory may grow indefinitely. This is most
+likely not an issue for clients, i.e. instances that only handle the local
+metrics. For servers it is recommended to set this to a non-zero value, though.
+
+You can set the limits using B<WriteQueueLimitHigh> and B<WriteQueueLimitLow>.
+Each of them takes a numerical argument which is the number of metrics in the
+queue. If there are I<HighNum> metrics in the queue, any new metrics I<will> be
+dropped. If there are less than I<LowNum> metrics in the queue, all new metrics
+I<will> be enqueued. If the number of metrics currently in the queue is between
+I<LowNum> and I<HighNum>, the metric is dropped with a probability that is
+proportional to the number of metrics in the queue (i.e. it increases linearly
+until it reaches 100%.)
+
+If B<WriteQueueLimitHigh> is set to non-zero and B<WriteQueueLimitLow> is
+unset, the latter will default to half of B<WriteQueueLimitHigh>.
+
+If you do not want to randomly drop values when the queue size is between
+I<LowNum> and I<HighNum>, set B<WriteQueueLimitHigh> and B<WriteQueueLimitLow>
+to the same value.
+
+Enabling the B<CollectInternalStats> option is of great help to figure out the
+values to set B<WriteQueueLimitHigh> and B<WriteQueueLimitLow> to.
+
+=item B<Hostname> I<Name>
+
+Sets the hostname that identifies a host. If you omit this setting, the
+hostname will be determined using the L<gethostname(2)> system call.
+
+=item B<FQDNLookup> B<true|false>
+
+If B<Hostname> is determined automatically this setting controls whether or not
+the daemon should try to figure out the "fully qualified domain name", FQDN.
+This is done using a lookup of the name returned by C<gethostname>. This option
+is enabled by default.
+
+=item B<PreCacheChain> I<ChainName>
+
+=item B<PostCacheChain> I<ChainName>
+
+Configure the name of the "pre-cache chain" and the "post-cache chain". Please
+see L<FILTER CONFIGURATION> below on information on chains and how these
+setting change the daemon's behavior.
+
+=back
+
+=head1 PLUGIN OPTIONS
+
+Some plugins may register own options. These options must be enclosed in a
+C<Plugin>-Section. Which options exist depends on the plugin used. Some plugins
+require external configuration, too. The C<apache plugin>, for example,
+required C<mod_status> to be configured in the webserver you're going to
+collect data from. These plugins are listed below as well, even if they don't
+require any configuration within collectd's configuration file.
+
+A list of all plugins and a short summary for each plugin can be found in the
+F<README> file shipped with the sourcecode and hopefully binary packets as
+well.
+
+=head2 Plugin C<aggregation>
+
+The I<Aggregation plugin> makes it possible to aggregate several values into
+one using aggregation functions such as I<sum>, I<average>, I<min> and I<max>.
+This can be put to a wide variety of uses, e.g. average and total CPU
+statistics for your entire fleet.
+
+The grouping is powerful but, as with many powerful tools, may be a bit
+difficult to wrap your head around. The grouping will therefore be
+demonstrated using an example: The average and sum of the CPU usage across
+all CPUs of each host is to be calculated.
+
+To select all the affected values for our example, set C<Plugin cpu> and
+C<Type cpu>. The other values are left unspecified, meaning "all values". The
+I<Host>, I<Plugin>, I<PluginInstance>, I<Type> and I<TypeInstance> options
+work as if they were specified in the C<WHERE> clause of an C<SELECT> SQL
+statement.
+
+  Plugin "cpu"
+  Type "cpu"
+
+Although the I<Host>, I<PluginInstance> (CPU number, i.e. 0, 1, 2, ...)  and
+I<TypeInstance> (idle, user, system, ...) fields are left unspecified in the
+example, the intention is to have a new value for each host / type instance
+pair. This is achieved by "grouping" the values using the C<GroupBy> option.
+It can be specified multiple times to group by more than one field.
+
+  GroupBy "Host"
+  GroupBy "TypeInstance"
+
+We do neither specify nor group by I<plugin instance> (the CPU number), so all
+metrics that differ in the CPU number only will be aggregated. Each
+aggregation needs I<at least one> such field, otherwise no aggregation would
+take place.
+
+The full example configuration looks like this:
+
+ <Plugin "aggregation">
+   <Aggregation>
+     Plugin "cpu"
+     Type "cpu"
+
+     GroupBy "Host"
+     GroupBy "TypeInstance"
+
+     CalculateSum true
+     CalculateAverage true
+   </Aggregation>
+ </Plugin>
+
+There are a couple of limitations you should be aware of:
+
+=over 4
+
+=item
+
+The I<Type> cannot be left unspecified, because it is not reasonable to add
+apples to oranges. Also, the internal lookup structure won't work if you try
+to group by type.
+
+=item
+
+There must be at least one unspecified, ungrouped field. Otherwise nothing
+will be aggregated.
+
+=back
+
+As you can see in the example above, each aggregation has its own
+B<Aggregation> block. You can have multiple aggregation blocks and aggregation
+blocks may match the same values, i.e. one value list can update multiple
+aggregations. The following options are valid inside B<Aggregation> blocks:
+
+=over 4
+
+=item B<Host> I<Host>
+
+=item B<Plugin> I<Plugin>
+
+=item B<PluginInstance> I<PluginInstance>
+
+=item B<Type> I<Type>
+
+=item B<TypeInstance> I<TypeInstance>
+
+Selects the value lists to be added to this aggregation. B<Type> must be a
+valid data set name, see L<types.db(5)> for details.
+
+If the string starts with and ends with a slash (C</>), the string is
+interpreted as a I<regular expression>. The regex flavor used are POSIX
+extended regular expressions as described in L<regex(7)>. Example usage:
+
+ Host "/^db[0-9]\\.example\\.com$/"
+
+=item B<GroupBy> B<Host>|B<Plugin>|B<PluginInstance>|B<TypeInstance>
+
+Group valued by the specified field. The B<GroupBy> option may be repeated to
+group by multiple fields.
+
+=item B<SetHost> I<Host>
+
+=item B<SetPlugin> I<Plugin>
+
+=item B<SetPluginInstance> I<PluginInstance>
+
+=item B<SetTypeInstance> I<TypeInstance>
+
+Sets the appropriate part of the identifier to the provided string.
+
+The I<PluginInstance> should include the placeholder C<%{aggregation}> which
+will be replaced with the aggregation function, e.g. "average". Not including
+the placeholder will result in duplication warnings and/or messed up values if
+more than one aggregation function are enabled.
+
+The following example calculates the average usage of all "even" CPUs:
+
+ <Plugin "aggregation">
+   <Aggregation>
+     Plugin "cpu"
+     PluginInstance "/[0,2,4,6,8]$/"
+     Type "cpu"
+
+     SetPlugin "cpu"
+     SetPluginInstance "even-%{aggregation}"
+
+     GroupBy "Host"
+     GroupBy "TypeInstance"
+
+     CalculateAverage true
+   </Aggregation>
+ </Plugin>
+
+This will create the files:
+
+=over 4
+
+=item
+
+foo.example.com/cpu-even-average/cpu-idle
+
+=item
+
+foo.example.com/cpu-even-average/cpu-system

+=item B<CalculateMinimum> B<true>|B<false>

+sum, average, minimum, maximum andE<nbsp>/ or standard deviation. All options
+are disabled by default.

+
+=head2 Plugin C<amqp>
+
+The I<AMQMP plugin> can be used to communicate with other instances of
+I<collectd> or third party applications using an AMQP message broker. Values
+are sent to or received from the broker, which handles routing, queueing and
+possibly filtering or messages.
+
+ <Plugin "amqp">
+   # Send values to an AMQP broker
+   <Publish "some_name">
+     Host "localhost"
+     Port "5672"
+     VHost "/"
+     User "guest"
+     Password "guest"
+     Exchange "amq.fanout"
+ #   ExchangeType "fanout"
+ #   RoutingKey "collectd"
+ #   Persistent false
+ #   ConnectionRetryDelay 0
+ #   Format "command"
+ #   StoreRates false
+ #   GraphitePrefix "collectd."
+ #   GraphiteEscapeChar "_"
+ #   GraphiteSeparateInstances false
+ #   GraphiteAlwaysAppendDS false
+   </Publish>
+
+   # Receive values from an AMQP broker
+   <Subscribe "some_name">
+     Host "localhost"
+     Port "5672"
+     VHost "/"
+     User "guest"
+     Password "guest"
+     Exchange "amq.fanout"
+ #   ExchangeType "fanout"
+ #   Queue "queue_name"
+ #   QueueDurable false
+ #   QueueAutoDelete true
+ #   RoutingKey "collectd.#"
+ #   ConnectionRetryDelay 0
+   </Subscribe>
+ </Plugin>
+
+The plugin's configuration consists of a number of I<Publish> and I<Subscribe>
+blocks, which configure sending and receiving of values respectively. The two
+blocks are very similar, so unless otherwise noted, an option can be used in
+either block. The name given in the blocks starting tag is only used for
+reporting messages, but may be used to support I<flushing> of certain
+I<Publish> blocks in the future.
+
+=over 4
+
+=item B<Host> I<Host>
+
+Hostname or IP-address of the AMQP broker. Defaults to the default behavior of
+the underlying communications library, I<rabbitmq-c>, which is "localhost".
+
+=item B<Port> I<Port>
+
+Service name or port number on which the AMQP broker accepts connections. This
+argument must be a string, even if the numeric form is used. Defaults to
+"5672".
+
+=item B<VHost> I<VHost>
+
+Name of the I<virtual host> on the AMQP broker to use. Defaults to "/".
+
+=item B<User> I<User>
+
+=item B<Password> I<Password>
+
+Credentials used to authenticate to the AMQP broker. By default "guest"/"guest"
+is used.
+
+=item B<Exchange> I<Exchange>
+
+In I<Publish> blocks, this option specifies the I<exchange> to send values to.
+By default, "amq.fanout" will be used.
+
+In I<Subscribe> blocks this option is optional. If given, a I<binding> between
+the given exchange and the I<queue> is created, using the I<routing key> if
+configured. See the B<Queue> and B<RoutingKey> options below.
+
+=item B<ExchangeType> I<Type>
+
+If given, the plugin will try to create the configured I<exchange> with this
+I<type> after connecting. When in a I<Subscribe> block, the I<queue> will then
+be bound to this exchange.
+
+=item B<Queue> I<Queue> (Subscribe only)
+
+Configures the I<queue> name to subscribe to. If no queue name was configured
+explicitly, a unique queue name will be created by the broker.
+
+=item B<QueueDurable> B<true>|B<false> (Subscribe only)
+
+Defines if the I<queue> subscribed to is durable (saved to persistent storage)
+or transient (will disappear if the AMQP broker is restarted). Defaults to
+"false".
+
+This option should be used in conjunction with the I<Persistent> option on the
+publish side.
+
+=item B<QueueAutoDelete> B<true>|B<false> (Subscribe only)
+
+Defines if the I<queue> subscribed to will be deleted once the last consumer
+unsubscribes. Defaults to "true".
+
+=item B<RoutingKey> I<Key>
+
+In I<Publish> blocks, this configures the routing key to set on all outgoing
+messages. If not given, the routing key will be computed from the I<identifier>
+of the value. The host, plugin, type and the two instances are concatenated
+together using dots as the separator and all containing dots replaced with
+slashes. For example "collectd.host/example/com.cpu.0.cpu.user". This makes it
+possible to receive only specific values using a "topic" exchange.
+
+In I<Subscribe> blocks, configures the I<routing key> used when creating a
+I<binding> between an I<exchange> and the I<queue>. The usual wildcards can be
+used to filter messages when using a "topic" exchange. If you're only
+interested in CPU statistics, you could use the routing key "collectd.*.cpu.#"
+for example.
+
+=item B<Persistent> B<true>|B<false> (Publish only)
+
+Selects the I<delivery method> to use. If set to B<true>, the I<persistent>
+mode will be used, i.e. delivery is guaranteed. If set to B<false> (the
+default), the I<transient> delivery mode will be used, i.e. messages may be
+lost due to high load, overflowing queues or similar issues.
+
+=item B<ConnectionRetryDelay> I<Delay>
+
+When the connection to the AMQP broker is lost, defines the time in seconds to
+wait before attempting to reconnect. Defaults to 0, which implies collectd will
+attempt to reconnect at each read interval (in Subscribe mode) or each time
+values are ready for submission (in Publish mode).
+
+=item B<Format> B<Command>|B<JSON>|B<Graphite> (Publish only)
+
+Selects the format in which messages are sent to the broker. If set to
+B<Command> (the default), values are sent as C<PUTVAL> commands which are
+identical to the syntax used by the I<Exec> and I<UnixSock plugins>. In this
+case, the C<Content-Type> header field will be set to C<text/collectd>.
+
+If set to B<JSON>, the values are encoded in the I<JavaScript Object Notation>,
+an easy and straight forward exchange format. The C<Content-Type> header field
+will be set to C<application/json>.
+
+If set to B<Graphite>, values are encoded in the I<Graphite> format, which is
+"<metric> <value> <timestamp>\n". The C<Content-Type> header field will be set to
+C<text/graphite>.
+
+A subscribing client I<should> use the C<Content-Type> header field to
+determine how to decode the values. Currently, the I<AMQP plugin> itself can
+only decode the B<Command> format.
+
+=item B<StoreRates> B<true>|B<false> (Publish only)
+
+Determines whether or not C<COUNTER>, C<DERIVE> and C<ABSOLUTE> data sources
+are converted to a I<rate> (i.e. a C<GAUGE> value). If set to B<false> (the
+default), no conversion is performed. Otherwise the conversion is performed
+using the internal value cache.
+
+Please note that currently this option is only used if the B<Format> option has
+been set to B<JSON>.
+
+=item B<GraphitePrefix> (Publish and B<Format>=I<Graphite> only)
+

+=head2 Plugin C<apache>
+
+To configure the C<apache>-plugin you first need to configure the Apache
+webserver correctly. The Apache-plugin C<mod_status> needs to be loaded and
+working and the C<ExtendedStatus> directive needs to be B<enabled>. You can use
+the following snipped to base your Apache config upon:
+
+  ExtendedStatus on
+  <IfModule mod_status.c>
+    <Location /mod_status>
+      SetHandler server-status
+    </Location>
+  </IfModule>
+
+Since its C<mod_status> module is very similar to Apache's, B<lighttpd> is
+also supported. It introduces a new field, called C<BusyServers>, to count the
+number of currently connected clients. This field is also supported.
+
+The configuration of the I<Apache> plugin consists of one or more
+C<E<lt>InstanceE<nbsp>/E<gt>> blocks. Each block requires one string argument
+as the instance name. For example:
+
+ <Plugin "apache">
+   <Instance "www1">
+     URL "http://www1.example.com/mod_status?auto"
+   </Instance>
+   <Instance "www2">
+     URL "http://www2.example.com/mod_status?auto"
+   </Instance>
+ </Plugin>
+
+The instance name will be used as the I<plugin instance>. To emulate the old
+(versionE<nbsp>4) behavior, you can use an empty string (""). In order for the
+plugin to work correctly, each instance name must be unique. This is not
+enforced by the plugin and it is your responsibility to ensure it.
+
+The following options are accepted within each I<Instance> block:
+
+=over 4
+
+=item B<URL> I<http://host/mod_status?auto>
+
+Sets the URL of the C<mod_status> output. This needs to be the output generated
+by C<ExtendedStatus on> and it needs to be the machine readable output
+generated by appending the C<?auto> argument. This option is I<mandatory>.

+
+
+=item I<BMP085> from Bosch Sensortec
+
+=back
+
+The sensor type - one of the above - is detected automatically by the plugin
+and indicated in the plugin_instance (you will see subdirectory
+"barometer-mpl115" or "barometer-mpl3115", or "barometer-bmp085"). The order of
+detection is BMP085 -> MPL3115 -> MPL115A2, the first one found will be used
+(only one sensor can be used by the plugin).
+
+The plugin provides absolute barometric pressure, air pressure reduced to sea
+level (several possible approximations) and as an auxiliary value also internal
+sensor temperature. It uses (expects/provides) typical metric units - pressure
+in [hPa], temperature in [C], altitude in [m].
+
+It was developed and tested under Linux only. The only platform dependency is
+the standard Linux i2c-dev interface (the particular bus driver has to
+support the SM Bus command subset).
+
+The reduction or normalization to mean sea level pressure requires (depending
+on selected method/approximation) also altitude and reference to temperature
+sensor(s).  When multiple temperature sensors are configured the minumum of
+their values is always used (expecting that the warmer ones are affected by
+e.g. direct sun light at that moment).

+=item B<Device> I<device>
+
+The only mandatory configuration parameter.
+
+Device name of the I2C bus to which the sensor is connected. Note that
+typically you need to have loaded the i2c-dev module.
+Using i2c-tools you can check/list i2c buses available on your system by:
+
+  i2cdetect -l
+
+Then you can scan for devices on given bus. E.g. to scan the whole bus 0 use:
+
+  i2cdetect -y -a 0
+
+This way you should be able to verify that the pressure sensor (either type) is
+connected and detected on address 0x60.
+
+=item B<Oversampling> I<value>
+
+Optional parameter controlling the oversampling/accuracy. Default value
+is 1 providing fastest and least accurate reading.
+
+For I<MPL115> this is the size of the averaging window. To filter out sensor
+noise a simple averaging using floating window of this configurable size is
+used. The plugin will use average of the last C<value> measurements (value of 1
+means no averaging).  Minimal size is 1, maximal 1024.
+
+For I<MPL3115> this is the oversampling value. The actual oversampling is
+performed by the sensor and the higher value the higher accuracy and longer
+conversion time (although nothing to worry about in the collectd context).
+Supported values are: 1, 2, 4, 8, 16, 32, 64 and 128. Any other value is
+adjusted by the plugin to the closest supported one.

+
+You can further calibrate the sensor by supplying pressure and/or temperature
+offsets.  This is added to the measured/caclulated value (i.e. if the measured
+value is too high then use negative offset).

+in particular when only C</proc/pmu> is available on an old Linux system.
+Defaults to B<false>.
+
+=item B<ReportDegraded> B<false>|B<true>
+
+Typical laptop batteries degrade over time, meaning the capacity decreases with
+recharge cycles. The maximum charge of the previous charge cycle is tracked as
+"last full capacity" and used to determine that a battery is "fully charged".
+
+When this option is set to B<false>, the default, the I<battery plugin> will
+only report the remaining capacity. If the B<ValuesPercentage> option is
+enabled, the relative remaining capacity is calculated as the ratio of the
+"remaining capacity" and the "last full capacity". This is what most tools,
+such as the status bar of desktop environments, also do.
+
+When set to B<true>, the battery plugin will report three values: B<charged>
+(remaining capacity), B<discharged> (difference between "last full capacity"
+and "remaining capacity") and B<degraded> (difference between "design capacity"
+and "last full capacity").

+=head2 Plugin C<bind>
+
+Starting with BIND 9.5.0, the most widely used DNS server software provides
+extensive statistics about queries, responses and lots of other information.
+The bind plugin retrieves this information that's encoded in XML and provided
+via HTTP and submits the values to collectd.
+
+To use this plugin, you first need to tell BIND to make this information
+available. This is done with the C<statistics-channels> configuration option:
+
+ statistics-channels {
+   inet localhost port 8053;
+ };
+
+The configuration follows the grouping that can be seen when looking at the
+data with an XSLT compatible viewer, such as a modern web browser. It's
+probably a good idea to make yourself familiar with the provided values, so you
+can understand what the collected statistics actually mean.

+This option is only considered when both, B<ReportByCpu> and B<ReportByState>
+are set to B<true>. In this case, by default, metrics will be reported as
+Jiffies. By setting this option to B<true>, you can request percentage values
+in the un-aggregated (per-CPU, per-state) mode as well.

+=head2 Plugin C<cpufreq>
+
+This plugin doesn't have any options. It reads
+F</sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq> (for the first CPU
+installed) to get the current CPU frequency. If this file does not exist make
+sure B<cpufreqd> (L<http://cpufreqd.sourceforge.net/>) or a similar tool is
+installed and an "cpu governor" (that's a kernel module) is loaded.

+
+=item B<DataDir> I<Directory>
+
+Set the directory to store CSV-files under. Per default CSV-files are generated
+beneath the daemon's working directory, i.E<nbsp>e. the B<BaseDir>.
+The special strings B<stdout> and B<stderr> can be used to write to the standard
+output and standard error channels, respectively. This, of course, only makes
+much sense when collectd is running in foreground- or non-daemon-mode.
+
+=item B<StoreRates> B<true|false>
+
+If set to B<true>, convert counter values to rates. If set to B<false> (the
+default) counter values are stored as is, i.E<nbsp>e. as an increasing integer
+number.

+
+=head2 Plugin C<curl>
+
+The curl plugin uses the B<libcurl> (L<http://curl.haxx.se/>) to read web pages
+and the match infrastructure (the same code used by the tail plugin) to use
+regular expressions with the received data.
+
+The following example will read the current value of AMD stock from Google's
+finance page and dispatch the value to collectd.
+
+  <Plugin curl>
+    <Page "stock_quotes">
+      URL "http://finance.google.com/finance?q=NYSE%3AAMD"
+      User "foo"
+      Password "bar"
+      Digest false
+      VerifyPeer true
+      VerifyHost true
+      CACert "/path/to/ca.crt"
+      Header "X-Custom-Header: foobar"
+      Post "foo=bar"
+
+      MeasureResponseTime false
+      MeasureResponseCode false
+
+      <Match>
+        Regex "<span +class=\"pr\"[^>]*> *([0-9]*\\.[0-9]+) *</span>"
+        DSType "GaugeAverage"
+        # Note: `stock_value' is not a standard type.
+        Type "stock_value"
+        Instance "AMD"
+      </Match>
+    </Page>
+  </Plugin>
+
+In the B<Plugin> block, there may be one or more B<Page> blocks, each defining
+a web page and one or more "matches" to be performed on the returned data. The
+string argument to the B<Page> block is used as plugin instance.
+
+The following options are valid within B<Page> blocks:
+
+=over 4
+
+=item B<URL> I<URL>
+
+URL of the web site to retrieve. Since a regular expression will be used to
+extract information from this data, non-binary data is a big plus here ;)
+
+=item B<User> I<Name>
+
+Username to use if authorization is required to read the page.
+
+=item B<Password> I<Password>
+
+Password to use if authorization is required to read the page.
+
+=item B<Digest> B<true>|B<false>
+
+Enable HTTP digest authentication.
+
+=item B<VerifyPeer> B<true>|B<false>
+
+Enable or disable peer SSL certificate verification. See
+L<http://curl.haxx.se/docs/sslcerts.html> for details. Enabled by default.
+
+=item B<VerifyHost> B<true>|B<false>
+
+Enable or disable peer host name verification. If enabled, the plugin checks if
+the C<Common Name> or a C<Subject Alternate Name> field of the SSL certificate
+matches the host name provided by the B<URL> option. If this identity check
+fails, the connection is aborted. Obviously, only works when connecting to a
+SSL enabled server. Enabled by default.
+
+=item B<CACert> I<file>
+
+File that holds one or more SSL certificates. If you want to use HTTPS you will
+possibly need this option. What CA certificates come bundled with C<libcurl>
+and are checked by default depends on the distribution you use.
+
+=item B<Header> I<Header>
+
+A HTTP header to add to the request. Multiple headers are added if this option
+is specified more than once.
+
+=item B<Post> I<Body>
+
+Specifies that the HTTP operation should be a POST instead of a GET. The
+complete data to be posted is given as the argument.  This option will usually
+need to be accompanied by a B<Header> option to set an appropriate
+C<Content-Type> for the post body (e.g. to
+C<application/x-www-form-urlencoded>).
+
+=item B<MeasureResponseTime> B<true>|B<false>
+
+Measure response time for the request. If this setting is enabled, B<Match>
+blocks (see below) are optional. Disabled by default.
+
+Beware that requests will get aborted if they take too long to complete. Adjust
+B<Timeout> accordingly if you expect B<MeasureResponseTime> to report such slow
+requests.
+
+=item B<MeasureResponseCode> B<true>|B<false>
+
+Measure response code for the request. If this setting is enabled, B<Match>
+blocks (see below) are optional. Disabled by default.
+
+=item B<E<lt>MatchE<gt>>
+
+One or more B<Match> blocks that define how to match information in the data
+returned by C<libcurl>. The C<curl> plugin uses the same infrastructure that's
+used by the C<tail> plugin, so please see the documentation of the C<tail>
+plugin below on how matches are defined. If the B<MeasureResponseTime> or
+B<MeasureResponseCode> options are set to B<true>, B<Match> blocks are
+optional.
+
+=item B<Timeout> I<Milliseconds>
+
+The B<Timeout> option sets the overall timeout for HTTP requests to B<URL>, in
+milliseconds. By default, the configured B<Interval> is used to set the
+timeout. Prior to version 5.5.0, there was no timeout and requests could hang
+indefinitely. This legacy behaviour can be achieved by setting the value of
+B<Timeout> to 0.
+
+If B<Timeout> is 0 or bigger than the B<Interval>, keep in mind that each slow
+network connection will stall one read thread. Adjust the B<ReadThreads> global
+setting accordingly to prevent this from blocking other plugins.

+=head2 Plugin C<curl_json>
+
+The B<curl_json plugin> collects values from JSON data to be parsed by
+B<libyajl> (L<http://www.lloydforge.org/projects/yajl/>) retrieved via
+either B<libcurl> (L<http://curl.haxx.se/>) or read directly from a
+unix socket. The former can be used, for example, to collect values
+from CouchDB documents (which are stored JSON notation), and the
+latter to collect values from a uWSGI stats socket.
+
+The following example will collect several values from the built-in
+C<_stats> runtime statistics module of I<CouchDB>
+(L<http://wiki.apache.org/couchdb/Runtime_Statistics>).

+      </Key>
+    </Sock>
+  </Plugin>
+
+In the B<Plugin> block, there may be one or more B<URL> blocks, each
+defining a URL to be fetched via HTTP (using libcurl) or B<Sock>
+blocks defining a unix socket to read JSON from directly.  Each of
+these blocks may have one or more B<Key> blocks.
+
+The B<Key> string argument must be in a path format. Each component is
+used to match the key from a JSON map or the index of an JSON
+array. If a path component of a B<Key> is a I<*>E<nbsp>wildcard, the
+values for all map keys or array indices will be collectd.
+
+The following options are valid within B<URL> blocks:

+
+Sets the plugin instance to I<Instance>.

+
+In the B<Plugin> block, there may be one or more B<URL> blocks, each defining a
+URL to be fetched using libcurl. Within each B<URL> block there are
+options which specify the connection parameters, for example authentication
+information, and one or more B<XPath> blocks.
+
+Each B<XPath> block specifies how to get one type of information. The
+string argument must be a valid XPath expression which returns a list
+of "base elements". One value is dispatched for each "base element". The
+I<type instance> and values are looked up using further I<XPath> expressions
+that should be relative to the base element.

+Use I<Instance> as the plugin instance when submitting values. Defaults to an
+empty string (no plugin instance).
+
+=item B<Namespace> I<Prefix> I<URL>
+
+If an XPath expression references namespaces, they must be specified
+with this option. I<Prefix> is the "namespace prefix" used in the XML document.
+I<URL> is the "namespace name", an URI reference uniquely identifying the
+namespace. The option can be repeated to register multiple namespaces.

+
+Specifies a XPath expression to use for determining the I<type instance>. The
+XPath expression must return exactly one element. The element's value is then
+used as I<type instance>, possibly prefixed with I<InstancePrefix> (see above).
+
+This value is required. As a special exception, if the "base XPath expression"
+(the argument to the B<XPath> block) returns exactly one argument, then this
+option may be omitted.

+=head2 Plugin C<dbi>
+
+This plugin uses the B<dbi> library (L<http://libdbi.sourceforge.net/>) to
+connect to various databases, execute I<SQL> statements and read back the
+results. I<dbi> is an acronym for "database interface" in case you were
+wondering about the name. You can configure how each column is to be
+interpreted and the plugin will generate one or more data sets from each row
+returned according to these rules.
+
+Because the plugin is very generic, the configuration is a little more complex
+than those of other plugins. It usually looks something like this:
+
+  <Plugin dbi>
+    <Query "out_of_stock">
+      Statement "SELECT category, COUNT(*) AS value FROM products WHERE in_stock = 0 GROUP BY category"
+      # Use with MySQL 5.0.0 or later
+      MinVersion 50000
+      <Result>
+        Type "gauge"
+        InstancePrefix "out_of_stock"
+        InstancesFrom "category"
+        ValuesFrom "value"
+      </Result>
+    </Query>
+    <Database "product_information">
+      Driver "mysql"
+      DriverOption "host" "localhost"
+      DriverOption "username" "collectd"
+      DriverOption "password" "aZo6daiw"
+      DriverOption "dbname" "prod_info"
+      SelectDB "prod_info"
+      Query "out_of_stock"
+    </Database>
+  </Plugin>
+
+The configuration above defines one query with one result and one database. The
+query is then linked to the database with the B<Query> option I<within> the
+B<E<lt>DatabaseE<gt>> block. You can have any number of queries and databases
+and you can also use the B<Include> statement to split up the configuration
+file in multiple, smaller files. However, the B<E<lt>QueryE<gt>> block I<must>
+precede the B<E<lt>DatabaseE<gt>> blocks, because the file is interpreted from
+top to bottom!
+
+The following is a complete list of options:
+
+=head3 B<Query> blocks
+
+Query blocks define I<SQL> statements and how the returned data should be
+interpreted. They are identified by the name that is given in the opening line
+of the block. Thus the name needs to be unique. Other than that, the name is
+not used in collectd.
+
+In each B<Query> block, there is one or more B<Result> blocks. B<Result> blocks
+define which column holds which value or instance information. You can use
+multiple B<Result> blocks to create multiple values from one returned row. This
+is especially useful, when queries take a long time and sending almost the same
+query again and again is not desirable.
+
+Example:
+
+  <Query "environment">
+    Statement "select station, temperature, humidity from environment"
+    <Result>
+      Type "temperature"
+      # InstancePrefix "foo"
+      InstancesFrom "station"
+      ValuesFrom "temperature"
+    </Result>
+    <Result>
+      Type "humidity"
+      InstancesFrom "station"
+      ValuesFrom "humidity"
+    </Result>
+  </Query>
+
+The following options are accepted:
+
+=over 4
+
+=item B<Statement> I<SQL>
+
+Sets the statement that should be executed on the server. This is B<not>
+interpreted by collectd, but simply passed to the database server. Therefore,
+the SQL dialect that's used depends on the server collectd is connected to.
+
+The query has to return at least two columns, one for the instance and one
+value. You cannot omit the instance, even if the statement is guaranteed to
+always return exactly one line. In that case, you can usually specify something
+like this:
+
+  Statement "SELECT \"instance\", COUNT(*) AS value FROM table"
+
+(That works with MySQL but may not be valid SQL according to the spec. If you
+use a more strict database server, you may have to select from a dummy table or
+something.)
+
+Please note that some databases, for example B<Oracle>, will fail if you
+include a semicolon at the end of the statement.
+
+=item B<MinVersion> I<Version>
+
+=item B<MaxVersion> I<Value>
+
+Only use this query for the specified database version. You can use these
+options to provide multiple queries with the same name but with a slightly
+different syntax. The plugin will use only those queries, where the specified
+minimum and maximum versions fit the version of the database in use.
+
+The database version is determined by C<dbi_conn_get_engine_version>, see the
+L<libdbi documentation|http://libdbi.sourceforge.net/docs/programmers-guide/reference-conn.html#DBI-CONN-GET-ENGINE-VERSION>
+for details. Basically, each part of the version is assumed to be in the range
+from B<00> to B<99> and all dots are removed. So version "4.1.2" becomes
+"40102", version "5.0.42" becomes "50042".
+
+B<Warning:> The plugin will use B<all> matching queries, so if you specify
+multiple queries with the same name and B<overlapping> ranges, weird stuff will
+happen. Don't to it! A valid example would be something along these lines:
+
+  MinVersion 40000
+  MaxVersion 49999
+  ...
+  MinVersion 50000
+  MaxVersion 50099
+  ...
+  MinVersion 50100
+  # No maximum
+
+In the above example, there are three ranges that don't overlap. The last one
+goes from version "5.1.0" to infinity, meaning "all later versions". Versions
+before "4.0.0" are not specified.
+
+=item B<Type> I<Type>
+
+The B<type> that's used for each line returned. See L<types.db(5)> for more
+details on how types are defined. In short: A type is a predefined layout of
+data and the number of values and type of values has to match the type
+definition.
+
+If you specify "temperature" here, you need exactly one gauge column. If you
+specify "if_octets", you will need two counter columns. See the B<ValuesFrom>
+setting below.
+
+There must be exactly one B<Type> option inside each B<Result> block.
+
+=item B<InstancePrefix> I<prefix>
+
+Prepends I<prefix> to the type instance. If B<InstancesFrom> (see below) is not
+given, the string is simply copied. If B<InstancesFrom> is given, I<prefix> and
+all strings returned in the appropriate columns are concatenated together,
+separated by dashes I<("-")>.
+
+=item B<InstancesFrom> I<column0> [I<column1> ...]
+
+Specifies the columns whose values will be used to create the "type-instance"
+for each row. If you specify more than one column, the value of all columns
+will be joined together with dashes I<("-")> as separation characters.
+
+The plugin itself does not check whether or not all built instances are
+different. It's your responsibility to assure that each is unique. This is
+especially true, if you do not specify B<InstancesFrom>: B<You> have to make
+sure that only one row is returned in this case.
+
+If neither B<InstancePrefix> nor B<InstancesFrom> is given, the type-instance
+will be empty.
+
+=item B<ValuesFrom> I<column0> [I<column1> ...]
+
+Names the columns whose content is used as the actual data for the data sets
+that are dispatched to the daemon. How many such columns you need is determined
+by the B<Type> setting above. If you specify too many or not enough columns,
+the plugin will complain about that and no data will be submitted to the
+daemon.
+
+The actual data type in the columns is not that important. The plugin will
+automatically cast the values to the right type if it know how to do that. So
+it should be able to handle integer an floating point types, as well as strings
+(if they include a number at the beginning).
+
+There must be at least one B<ValuesFrom> option inside each B<Result> block.
+
+=item B<MetadataFrom> [I<column0> I<column1> ...]
+
+Names the columns whose content is used as metadata for the data sets
+that are dispatched to the daemon.
+
+The actual data type in the columns is not that important. The plugin will
+automatically cast the values to the right type if it know how to do that. So
+it should be able to handle integer an floating point types, as well as strings
+(if they include a number at the beginning).
+
+=back
+
+=head3 B<Database> blocks
+
+Database blocks define a connection to a database and which queries should be
+sent to that database. Since the used "dbi" library can handle a wide variety
+of databases, the configuration is very generic. If in doubt, refer to libdbi's
+documentationE<nbsp>- we stick as close to the terminology used there.
+
+Each database needs a "name" as string argument in the starting tag of the
+block. This name will be used as "PluginInstance" in the values submitted to
+the daemon. Other than that, that name is not used.
+
+=over 4
+
+=item B<Driver> I<Driver>
+
+Specifies the driver to use to connect to the database. In many cases those
+drivers are named after the database they can connect to, but this is not a
+technical necessity. These drivers are sometimes referred to as "DBD",
+B<D>ataB<B>ase B<D>river, and some distributions ship them in separate
+packages. Drivers for the "dbi" library are developed by the B<libdbi-drivers>
+project at L<http://libdbi-drivers.sourceforge.net/>.
+
+You need to give the driver name as expected by the "dbi" library here. You
+should be able to find that in the documentation for each driver. If you
+mistype the driver name, the plugin will dump a list of all known driver names
+to the log.
+
+=item B<DriverOption> I<Key> I<Value>
+
+Sets driver-specific options. What option a driver supports can be found in the
+documentation for each driver, somewhere at
+L<http://libdbi-drivers.sourceforge.net/>. However, the options "host",
+"username", "password", and "dbname" seem to be deE<nbsp>facto standards.
+
+DBDs can register two types of options: String options and numeric options. The
+plugin will use the C<dbi_conn_set_option> function when the configuration
+provides a string and the C<dbi_conn_require_option_numeric> function when the
+configuration provides a number. So these two lines will actually result in
+different calls being used:
+
+  DriverOption "Port" 1234      # numeric
+  DriverOption "Port" "1234"    # string
+
+Unfortunately, drivers are not too keen to report errors when an unknown option
+is passed to them, so invalid settings here may go unnoticed. This is not the
+plugin's fault, it will report errors if it gets them from the libraryE<nbsp>/
+the driver. If a driver complains about an option, the plugin will dump a
+complete list of all options understood by that driver to the log. There is no
+way to programatically find out if an option expects a string or a numeric
+argument, so you will have to refer to the appropriate DBD's documentation to
+find this out. Sorry.
+
+=item B<SelectDB> I<Database>
+
+In some cases, the database name you connect with is not the database name you
+want to use for querying data. If this option is set, the plugin will "select"
+(switch to) that database after the connection is established.
+
+=item B<Query> I<QueryName>
+
+Associates the query named I<QueryName> with this database connection. The
+query needs to be defined I<before> this statement, i.E<nbsp>e. all query
+blocks you want to refer to must be placed above the database block you want to

+=head2 Plugin C<disk>
+
+The C<disk> plugin collects information about the usage of physical disks and
+logical disks (partitions). Values collected are the number of octets written
+to and read from a disk or partition, the number of read/write operations
+issued to the disk and a rather complex "time" it took for these commands to be
+issued.
+
+Using the following two options you can ignore some disks or configure the
+collection only of specific disks.
+

+=item B<Disk> I<Name>
+
+Select the disk I<Name>. Whether it is collected or ignored depends on the
+B<IgnoreSelected> setting, see below. As with other plugins that use the
+daemon's ignorelist functionality, a string that starts and ends with a slash
+is interpreted as a regular expression. Examples:
+
+  Disk "sdd"
+  Disk "/hda[34]/"
+
+=item B<IgnoreSelected> B<true>|B<false>
+
+Sets whether selected disks, i.E<nbsp>e. the ones matches by any of the B<Disk>
+statements, are ignored or if all other disks are ignored. The behavior
+(hopefully) is intuitive: If no B<Disk> option is configured, all disks are
+collected. If at least one B<Disk> option is given and no B<IgnoreSelected> or
+set to B<false>, B<only> matching disks will be collected. If B<IgnoreSelected>
+is set to B<true>, all disks are collected B<except> the ones matched.

+
+Please note that in order to change the user and/or group the daemon needs
+superuser privileges. If the daemon is run as an unprivileged user you must
+specify the same user/group here. If the daemon is run with superuser
+privileges, you must supply a non-root user here.

+The executable may be followed by optional arguments that are passed to the

+=head2 Plugin C<fhcount>
+
+The C<fhcount> plugin provides statistics about used, unused and total number of
+file handles.
+
+The I<fhcount plugin> provides the following configuration options:
+
+=over 4
+
+=item B<ValuesAbsolute> B<true>|B<false>
+
+Enables or disables reporting of file handles usage in absolute numbers,
+e.g. file handles used. Defaults to B<true>.

+
+Enables or disables reporting of file handles usage in percentages, e.g.
+percent of file handles used. Defaults to B<false>.
+
+=back
+
+=head2 Plugin C<filecount>
+
+The C<filecount> plugin counts the number of files in a certain directory (and
+its subdirectories) and their combined size. The configuration is very straight
+forward:
+
+  <Plugin "filecount">
+    <Directory "/var/qmail/queue/mess">
+      Instance "qmail-message"
+    </Directory>
+    <Directory "/var/qmail/queue/todo">
+      Instance "qmail-todo"
+    </Directory>
+    <Directory "/var/lib/php5">
+      Instance "php5-sessions"
+      Name "sess_*"
+    </Directory>
+  </Plugin>
+
+The example above counts the number of files in QMail's queue directories and
+the number of PHP5 sessions. Jfiy: The "todo" queue holds the messages that
+QMail has not yet looked at, the "message" queue holds the messages that were
+classified into "local" and "remote".
+
+As you can see, the configuration consists of one or more C<Directory> blocks,
+each of which specifies a directory in which to count the files. Within those
+blocks, the following options are recognized:
+
+=over 4
+
+=item B<Instance> I<Instance>
+
+Sets the plugin instance to I<Instance>. That instance name must be unique, but
+it's your responsibility, the plugin doesn't check for that. If not given, the
+instance is set to the directory name with all slashes replaced by underscores
+and all leading underscores removed.
+
+=item B<Name> I<Pattern>
+
+Only count files that match I<Pattern>, where I<Pattern> is a shell-like
+wildcard as understood by L<fnmatch(3)>. Only the B<filename> is checked
+against the pattern, not the entire path. In case this makes it easier for you:
+This option has been named after the B<-name> parameter to L<find(1)>.
+
+=item B<MTime> I<Age>
+
+Count only files of a specific age: If I<Age> is greater than zero, only files
+that haven't been touched in the last I<Age> seconds are counted. If I<Age> is
+a negative number, this is inversed. For example, if B<-60> is specified, only
+files that have been modified in the last minute will be counted.
+
+The number can also be followed by a "multiplier" to easily specify a larger
+timespan. When given in this notation, the argument must in quoted, i.E<nbsp>e.
+must be passed as string. So the B<-60> could also be written as B<"-1m"> (one
+minute). Valid multipliers are C<s> (second), C<m> (minute), C<h> (hour), C<d>
+(day), C<w> (week), and C<y> (year). There is no "month" multiplier. You can
+also specify fractional numbers, e.E<nbsp>g. B<"0.5d"> is identical to
+B<"12h">.
+
+=item B<Size> I<Size>
+
+Count only files of a specific size. When I<Size> is a positive number, only
+files that are at least this big are counted. If I<Size> is a negative number,
+this is inversed, i.E<nbsp>e. only files smaller than the absolute value of
+I<Size> are counted.
+
+As with the B<MTime> option, a "multiplier" may be added. For a detailed
+description see above. Valid multipliers here are C<b> (byte), C<k> (kilobyte),
+C<m> (megabyte), C<g> (gigabyte), C<t> (terabyte), and C<p> (petabyte). Please
+note that there are 1000 bytes in a kilobyte, not 1024.
+
+=item B<Recursive> I<true>|I<false>
+
+Controls whether or not to recurse into subdirectories. Enabled by default.
+
+=item B<IncludeHidden> I<true>|I<false>
+
+Controls whether or not to include "hidden" files and directories in the count.
+"Hidden" files and directories are those, whose name begins with a dot.

+The C<memcachec plugin> connects to a memcached server, queries one or more
+given I<pages> and parses the returned data according to user specification.
+The I<matches> used are the same as the matches used in the C<curl> and C<tail>
+plugins.
+
+In order to talk to the memcached server, this plugin uses the I<libmemcached>
+library. Please note that there is another library with a very similar name,
+libmemcache (notice the missing `d'), which is not applicable.

+
+The configuration options are:
+
+=over 4
+
+=item E<lt>B<Page> I<Name>E<gt>
+
+Each B<Page> block defines one I<page> to be queried from the memcached server.

+
+The C<mysql plugin> requires B<mysqlclient> to be installed. It connects to
+one or more databases when started and keeps the connection up as long as
+possible. When the connection is interrupted for whatever reason it will try
+to re-connect. The plugin will complain loudly in case anything goes wrong.
+
+This plugin issues the MySQL C<SHOW STATUS> / C<SHOW GLOBAL STATUS> command
+and collects information about MySQL network traffic, executed statements,
+requests, the query cache and threads by evaluating the
+C<Bytes_{received,sent}>, C<Com_*>, C<Handler_*>, C<Qcache_*> and C<Threads_*>
+return values. Please refer to the B<MySQL reference manual>, I<5.1.6. Server
+Status Variables> for an explanation of these values.
+
+Optionally, master and slave statistics may be collected in a MySQL
+replication setup. In that case, information about the synchronization state
+of the nodes are collected by evaluating the C<Position> return value of the
+C<SHOW MASTER STATUS> command and the C<Seconds_Behind_Master>,
+C<Read_Master_Log_Pos> and C<Exec_Master_Log_Pos> return values of the
+C<SHOW SLAVE STATUS> command. See the B<MySQL reference manual>,

+
+The netapp plugin can collect various performance and capacity information
+from a NetApp filer using the NetApp API.
+
+Please note that NetApp has a wide line of products and a lot of different
+software versions for each of these products. This plugin was developed for a
+NetApp FAS3040 running OnTap 7.2.3P8 and tested on FAS2050 7.3.1.1L1,
+FAS3140 7.2.5.1 and FAS3020 7.2.4P9. It I<should> work for most combinations of
+model and software version but it is very hard to test this.
+If you have used this plugin with other models and/or software version, feel
+free to send us a mail to tell us about the results, even if it's just a short
+"It works".
+
+To collect these data collectd will log in to the NetApp via HTTP(S) and HTTP
+basic authentication.
+
+B<Do not use a regular user for this!> Create a special collectd user with just
+the minimum of capabilities needed. The user only needs the "login-http-admin"
+capability as well as a few more depending on which data will be collected.
+Required capabilities are documented below.

+plugin_instance.
+

+
+=item B<VerboseInterface> I<Interface>
+
+Instruct the plugin to collect interface statistics. This is basically the same
+as the statistics provided by the C<interface> plugin (see above) but
+potentially much more detailed.
+
+When configuring with B<Interface> only the basic statistics will be collected,
+namely octets, packets, and errors. These statistics are collected by
+the C<interface> plugin, too, so using both at the same time is no benefit.
+
+When configured with B<VerboseInterface> all counters B<except> the basic ones,
+so that no data needs to be collected twice if you use the C<interface> plugin.
+This includes dropped packets, received multicast packets, collisions and a
+whole zoo of differentiated RX and TX errors. You can try the following command
+to get an idea of what awaits you:
+
+  ip -s -s link list
+
+If I<Interface> is B<All>, all interfaces will be selected.
+
+=item B<QDisc> I<Interface> [I<QDisc>]
+
+=item B<Class> I<Interface> [I<Class>]
+
+=item B<Filter> I<Interface> [I<Filter>]
+
+Collect the octets and packets that pass a certain qdisc, class or filter.
+
+QDiscs and classes are identified by their type and handle (or classid).
+Filters don't necessarily have a handle, therefore the parent's handle is used.
+The notation used in collectd differs from that used in tc(1) in that it
+doesn't skip the major or minor number if it's zero and doesn't print special
+ids by their name. So, for example, a qdisc may be identified by
+C<pfifo_fast-1:0> even though the minor number of B<all> qdiscs is zero and
+thus not displayed by tc(1).
+
+If B<QDisc>, B<Class>, or B<Filter> is given without the second argument,
+i.E<nbsp>.e. without an identifier, all qdiscs, classes, or filters that are
+associated with that interface will be collected.
+
+Since a filter itself doesn't necessarily have a handle, the parent's handle is
+used. This may lead to problems when more than one filter is attached to a
+qdisc or class. This isn't nice, but we don't know how this could be done any
+better. If you have a idea, please don't hesitate to tell us.
+
+As with the B<Interface> option you can specify B<All> as the interface,
+meaning all interfaces.
+
+Here are some examples to help you understand the above text more easily:
+
+  <Plugin netlink>
+    VerboseInterface "All"
+    QDisc "eth0" "pfifo_fast-1:0"
+    QDisc "ppp0"
+    Class "ppp0" "htb-1:10"
+    Filter "ppp0" "u32-1:0"
+  </Plugin>
+
+=item B<IgnoreSelected>
+
+The behavior is the same as with all other similar plugins: If nothing is
+selected at all, everything is collected. If some things are selected using the
+options described above, only these statistics are collected. If you set
+B<IgnoreSelected> to B<true>, this behavior is inverted, i.E<nbsp>e. the
+specified statistics will not be collected.
+
+=back
+
+=head2 Plugin C<network>
+
+The Network plugin sends data to a remote instance of collectd, receives data
+from a remote instance, or both at the same time. Data which has been received
+from the network is usually not transmitted again, but this can be activated, see
+the B<Forward> option below.
+
+The default IPv6 multicast group is C<ff18::efc0:4a42>. The default IPv4
+multicast group is C<239.192.74.66>. The default I<UDP> port is B<25826>.
+
+Both, B<Server> and B<Listen> can be used as single option or as block. When
+used as block, given options are valid for this socket only. The following
+example will export the metrics twice: Once to an "internal" server (without
+encryption and signing) and one to an external server (with cryptographic
+signature):
+
+ <Plugin "network">
+   # Export to an internal server
+   # (demonstrates usage without additional options)
+   Server "collectd.internal.tld"
+
+   # Export to an external server
+   # (demonstrates usage with signature options)
+   <Server "collectd.external.tld">
+     SecurityLevel "sign"
+     Username "myhostname"
+     Password "ohl0eQue"
+   </Server>
+ </Plugin>
+
+=over 4
+
+=item B<E<lt>Server> I<Host> [I<Port>]B<E<gt>>
+
+The B<Server> statement/block sets the server to send datagrams to. The
+statement may occur multiple times to send each datagram to multiple
+destinations.
+
+The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. The
+optional second argument specifies a port number or a service name. If not
+given, the default, B<25826>, is used.
+
+The following options are recognized within B<Server> blocks:
+
+=over 4
+
+=item B<SecurityLevel> B<Encrypt>|B<Sign>|B<None>
+
+Set the security you require for network communication. When the security level
+has been set to B<Encrypt>, data sent over the network will be encrypted using
+I<AES-256>. The integrity of encrypted packets is ensured using I<SHA-1>. When
+set to B<Sign>, transmitted data is signed using the I<HMAC-SHA-256> message
+authentication code. When set to B<None>, data is sent without any security.
+
+This feature is only available if the I<network> plugin was linked with
+I<libgcrypt>.
+
+=item B<Username> I<Username>
+
+Sets the username to transmit. This is used by the server to lookup the
+password. See B<AuthFile> below. All security levels except B<None> require
+this setting.
+
+This feature is only available if the I<network> plugin was linked with
+I<libgcrypt>.
+
+=item B<Password> I<Password>
+
+Sets a password (shared secret) for this socket. All security levels except
+B<None> require this setting.
+
+This feature is only available if the I<network> plugin was linked with
+I<libgcrypt>.
+
+=item B<Interface> I<Interface name>
+
+Set the outgoing interface for IP packets. This applies at least
+to IPv6 packets and if possible to IPv4. If this option is not applicable,
+undefined or a non-existent interface name is specified, the default
+behavior is to let the kernel choose the appropriate interface. Be warned
+that the manual selection of an interface for unicast traffic is only
+necessary in rare cases.
+
+=item B<ResolveInterval> I<Seconds>
+
+Sets the interval at which to re-resolve the DNS for the I<Host>. This is
+useful to force a regular DNS lookup to support a high availability setup. If
+not specified, re-resolves are never attempted.
+
+=back
+
+=item B<E<lt>Listen> I<Host> [I<Port>]B<E<gt>>
+
+The B<Listen> statement sets the interfaces to bind to. When multiple
+statements are found the daemon will bind to multiple interfaces.
+
+The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. If
+the argument is a multicast address the daemon will join that multicast group.
+The optional second argument specifies a port number or a service name. If not
+given, the default, B<25826>, is used.
+
+The following options are recognized within C<E<lt>ListenE<gt>> blocks:
+
+=over 4
+
+=item B<SecurityLevel> B<Encrypt>|B<Sign>|B<None>
+
+Set the security you require for network communication. When the security level
+has been set to B<Encrypt>, only encrypted data will be accepted. The integrity
+of encrypted packets is ensured using I<SHA-1>. When set to B<Sign>, only
+signed and encrypted data is accepted. When set to B<None>, all data will be
+accepted. If an B<AuthFile> option was given (see below), encrypted data is
+decrypted if possible.
+
+This feature is only available if the I<network> plugin was linked with
+I<libgcrypt>.
+
+=item B<AuthFile> I<Filename>
+
+Sets a file in which usernames are mapped to passwords. These passwords are
+used to verify signatures and to decrypt encrypted network packets. If
+B<SecurityLevel> is set to B<None>, this is optional. If given, signed data is
+verified and encrypted packets are decrypted. Otherwise, signed data is
+accepted without checking the signature and encrypted data cannot be decrypted.
+For the other security levels this option is mandatory.
+
+The file format is very simple: Each line consists of a username followed by a
+colon and any number of spaces followed by the password. To demonstrate, an
+example file could look like this:
+
+  user0: foo
+  user1: bar
+
+Each time a packet is received, the modification time of the file is checked
+using L<stat(2)>. If the file has been changed, the contents is re-read. While
+the file is being read, it is locked using L<fcntl(2)>.
+
+=item B<Interface> I<Interface name>
+
+Set the incoming interface for IP packets explicitly. This applies at least
+to IPv6 packets and if possible to IPv4. If this option is not applicable,
+undefined or a non-existent interface name is specified, the default
+behavior is, to let the kernel choose the appropriate interface. Thus incoming
+traffic gets only accepted, if it arrives on the given interface.
+
+=back
+
+=item B<TimeToLive> I<1-255>
+
+Set the time-to-live of sent packets. This applies to all, unicast and
+multicast, and IPv4 and IPv6 packets. The default is to not change this value.
+That means that multicast packets will be sent with a TTL of C<1> (one) on most
+operating systems.
+
+=item B<MaxPacketSize> I<1024-65535>
+
+Set the maximum size for datagrams received over the network. Packets larger
+than this will be truncated. Defaults to 1452E<nbsp>bytes, which is the maximum
+payload size that can be transmitted in one Ethernet frame using IPv6E<nbsp>/
+UDP.
+
+On the server side, this limit should be set to the largest value used on
+I<any> client. Likewise, the value on the client must not be larger than the
+value on the server, or data will be lost.
+
+B<Compatibility:> Versions prior to I<versionE<nbsp>4.8> used a fixed sized
+buffer of 1024E<nbsp>bytes. Versions I<4.8>, I<4.9> and I<4.10> used a default
+value of 1024E<nbsp>bytes to avoid problems when sending data to an older
+server.
+
+=item B<Forward> I<true|false>
+
+If set to I<true>, write packets that were received via the network plugin to
+the sending sockets. This should only be activated when the B<Listen>- and
+B<Server>-statements differ. Otherwise packets may be send multiple times to
+the same multicast group. While this results in more network traffic than
+necessary it's not a huge problem since the plugin has a duplicate detection,
+so the values will not loop.
+
+=item B<ReportStats> B<true>|B<false>
+
+The network plugin cannot only receive and send statistics, it can also create
+statistics about itself. Collected data included the number of received and
+sent octets and packets, the length of the receive queue and the number of
+values handled. When set to B<true>, the I<Network plugin> will make these
+statistics available. Defaults to B<false>.

+=head2 Plugin C<onewire>
+
+B<EXPERIMENTAL!> See notes below.
+
+The C<onewire> plugin uses the B<owcapi> library from the B<owfs> project
+L<http://owfs.org/> to read sensors connected via the onewire bus.
+
+It can be used in two possible modes - standard or advanced.
+
+In the standard mode only temperature sensors (sensors with the family code
+C<10>, C<22> and C<28> - e.g. DS1820, DS18S20, DS1920) can be read. If you have
+other sensors you would like to have included, please send a sort request to
+the mailing list. You can select sensors to be read or to be ignored depending
+on the option B<IgnoreSelected>). When no list is provided the whole bus is
+walked and all sensors are read.
+
+Hubs (the DS2409 chips) are working, but read the note, why this plugin is
+experimental, below.
+
+In the advanced mode you can configure any sensor to be read (only numerical
+value) using full OWFS path (e.g. "/uncached/10.F10FCA000800/temperature").
+In this mode you have to list all the sensors. Neither default bus walk nor
+B<IgnoreSelected> are used here. Address and type (file) is extracted from
+the path automatically and should produce compatible structure with the "standard"
+mode (basically the path is expected as for example
+"/uncached/10.F10FCA000800/temperature" where it would extract address part
+"F10FCA000800" and the rest after the slash is considered the type - here
+"temperature").
+There are two advantages to this mode - you can access virtually any sensor
+(not just temperature), select whether to use cached or directly read values
+and it is slighlty faster. The downside is more complex configuration.
+
+The two modes are distinguished automatically by the format of the address.
+It is not possible to mix the two modes. Once a full path is detected in any
+B<Sensor> then the whole addressing (all sensors) is considered to be this way
+(and as standard addresses will fail parsing they will be ignored).
+
+=over 4
+
+=item B<Device> I<Device>
+
+Sets the device to read the values from. This can either be a "real" hardware
+device, such as a serial port or an USB port, or the address of the
+L<owserver(1)> socket, usually B<localhost:4304>.
+
+Though the documentation claims to automatically recognize the given address
+format, with versionE<nbsp>2.7p4 we had to specify the type explicitly. So
+with that version, the following configuration worked for us:
+
+  <Plugin onewire>
+    Device "-s localhost:4304"
+  </Plugin>
+
+This directive is B<required> and does not have a default value.
+
+=item B<Sensor> I<Sensor>
+
+In the standard mode selects sensors to collect or to ignore
+(depending on B<IgnoreSelected>, see below). Sensors are specified without
+the family byte at the beginning, so you have to use for example C<F10FCA000800>,
+and B<not> include the leading C<10.> family byte and point.
+When no B<Sensor> is configured the whole Onewire bus is walked and all supported
+sensors (see above) are read.
+
+In the advanced mode the B<Sensor> specifies full OWFS path - e.g.
+C</uncached/10.F10FCA000800/temperature> (or when cached values are OK
+C</10.F10FCA000800/temperature>). B<IgnoreSelected> is not used.
+
+As there can be multiple devices on the bus you can list multiple sensor (use
+multiple B<Sensor> elements).
+
+=item B<IgnoreSelected> I<true>|I<false>
+
+If no configuration is given, the B<onewire> plugin will collect data from all
+sensors found. This may not be practical, especially if sensors are added and
+removed regularly. Sometimes, however, it's easier/preferred to collect only
+specific sensors or all sensors I<except> a few specified ones. This option
+enables you to do that: By setting B<IgnoreSelected> to I<true> the effect of
+B<Sensor> is inverted: All selected interfaces are ignored and all other
+interfaces are collected.
+
+Used only in the standard mode - see above.
+
+=item B<Interval> I<Seconds>
+
+Sets the interval in which all sensors should be read. If not specified, the
+global B<Interval> setting is used.
+
+=back
+
+B<EXPERIMENTAL!> The C<onewire> plugin is experimental, because it doesn't yet
+work with big setups. It works with one sensor being attached to one
+controller, but as soon as you throw in a couple more senors and maybe a hub
+or two, reading all values will take more than ten seconds (the default
+interval). We will probably add some separate thread for reading the sensors
+and some cache or something like that, but it's not done yet. We will try to
+maintain backwards compatibility in the future, but we can't promise. So in
+short: If it works for you: Great! But keep in mind that the config I<might>
+change, though this is unlikely. Oh, and if you want to help improving this
+plugin, just send a short notice to the mailing list. ThanksE<nbsp>:)
+
+=head2 Plugin C<openldap>
+
+To use the C<openldap> plugin you first need to configure the I<OpenLDAP>
+server correctly. The backend database C<monitor> needs to be loaded and
+working. See slapd-monitor(5) for the details.
+
+The configuration of the C<openldap> plugin consists of one or more B<Instance>
+blocks. Each block requires one string argument as the instance name. For
+example:
+
+ <Plugin "openldap">
+   <Instance "foo">
+     URL "ldap://localhost/"
+   </Instance>
+   <Instance "bar">
+     URL "ldaps://localhost/"
+   </Instance>
+ </Plugin>
+
+The instance name will be used as the I<plugin instance>. To emulate the old
+(versionE<nbsp>4) behavior, you can use an empty string (""). In order for the
+plugin to work correctly, each instance name must be unique. This is not
+enforced by the plugin and it is your responsibility to ensure it is.
+
+The following options are accepted within each B<Instance> block:
+
+=over 4
+
+=item B<URL> I<ldap://host/binddn>
+
+Sets the URL to use to connect to the I<OpenLDAP> server. This option is
+I<mandatory>.
+
+=item B<StartTLS> B<true|false>
+
+Defines whether TLS must be used when connecting to the I<OpenLDAP> server.
+Disabled by default.
+
+=item B<VerifyHost> B<true|false>
+
+Enables or disables peer host name verification. If enabled, the plugin checks
+if the C<Common Name> or a C<Subject Alternate Name> field of the SSL
+certificate matches the host name provided by the B<URL> option. If this
+identity check fails, the connection is aborted. Enabled by default.
+
+=item B<CACert> I<File>
+
+File that holds one or more SSL certificates. If you want to use TLS/SSL you
+may possibly need this option. What CA certificates are checked by default
+depends on the distribution you use and can be changed with the usual ldap
+client configuration mechanisms. See ldap.conf(5) for the details.
+
+=item B<Timeout> I<Seconds>
+
+Sets the timeout value for ldap operations. Defaults to B<-1> which results in
+an infinite timeout.
+
+=item B<Version> I<Version>
+
+An integer which sets the LDAP protocol version number to use when connecting
+to the I<OpenLDAP> server. Defaults to B<3> for using I<LDAPv3>.
+
+=back
+
+=head2 Plugin C<openvpn>
+
+The OpenVPN plugin reads a status file maintained by OpenVPN and gathers
+traffic statistics about connected clients.
+
+To set up OpenVPN to write to the status file periodically, use the
+B<--status> option of OpenVPN. Since OpenVPN can write two different formats,
+you need to set the required format, too. This is done by setting
+B<--status-version> to B<2>.
+
+So, in a nutshell you need:
+
+  openvpn $OTHER_OPTIONS \
+    --status "/var/run/openvpn-status" 10 \
+    --status-version 2
+
+Available options:
+
+=over 4
+
+=item B<StatusFile> I<File>
+
+Specifies the location of the status file.
+
+=item B<ImprovedNamingSchema> B<true>|B<false>
+
+When enabled, the filename of the status file will be used as plugin instance
+and the client's "common name" will be used as type instance. This is required
+when reading multiple status files. Enabling this option is recommended, but to
+maintain backwards compatibility this option is disabled by default.
+
+=item B<CollectCompression> B<true>|B<false>
+
+Sets whether or not statistics about the compression used by OpenVPN should be
+collected. This information is only available in I<single> mode. Enabled by
+default.
+
+=item B<CollectIndividualUsers> B<true>|B<false>
+
+Sets whether or not traffic information is collected for each connected client
+individually. If set to false, currently no traffic data is collected at all
+because aggregating this data in a save manner is tricky. Defaults to B<true>.
+
+=item B<CollectUserCount> B<true>|B<false>
+
+When enabled, the number of currently connected clients or users is collected.
+This is especially interesting when B<CollectIndividualUsers> is disabled, but
+can be configured independently from that option. Defaults to B<false>.

+=head2 Plugin C<oracle>
+
+The "oracle" plugin uses the Oracle® Call Interface I<(OCI)> to connect to an
+Oracle® Database and lets you execute SQL statements there. It is very similar
+to the "dbi" plugin, because it was written around the same time. See the "dbi"
+plugin's documentation above for details.
+
+  <Plugin oracle>
+    <Query "out_of_stock">
+      Statement "SELECT category, COUNT(*) AS value FROM products WHERE in_stock = 0 GROUP BY category"

+
+The Query blocks are handled identically to the Query blocks of the "dbi"
+plugin. Please see its documentation above for details on how to specify
+queries.
+
+=head3 B<Database> blocks
+
+Database blocks define a connection to a database and which queries should be
+sent to that database. Each database needs a "name" as string argument in the
+starting tag of the block. This name will be used as "PluginInstance" in the
+values submitted to the daemon. Other than that, that name is not used.
+
+=over 4
+
+=item B<ConnectID> I<ID>

+=head2 Plugin C<perl>
+
+This plugin embeds a Perl-interpreter into collectd and provides an interface
+to collectd's plugin system. See L<collectd-perl(5)> for its documentation.
+
+=head2 Plugin C<pinba>
+
+The I<Pinba plugin> receives profiling information from I<Pinba>, an extension
+for the I<PHP> interpreter. At the end of executing a script, i.e. after a
+PHP-based webpage has been delivered, the extension will send a UDP packet
+containing timing information, peak memory usage and so on. The plugin will
+wait for such packets, parse them and account the provided information, which
+is then dispatched to the daemon once per interval.
+
+Synopsis:
+
+ <Plugin pinba>
+   Address "::0"
+   Port "30002"
+   # Overall statistics for the website.
+   <View "www-total">
+     Server "www.example.com"
+   </View>
+   # Statistics for www-a only
+   <View "www-a">
+     Host "www-a.example.com"
+     Server "www.example.com"
+   </View>
+   # Statistics for www-b only
+   <View "www-b">
+     Host "www-b.example.com"
+     Server "www.example.com"
+   </View>
+ </Plugin>
+
+The plugin provides the following configuration options:
+
+=over 4
+
+=item B<Address> I<Node>
+
+Configures the address used to open a listening socket. By default, plugin will
+bind to the I<any> address C<::0>.
+
+=item B<Port> I<Service>
+
+Configures the port (service) to bind to. By default the default Pinba port
+"30002" will be used. The option accepts service names in addition to port
+numbers and thus requires a I<string> argument.
+
+=item E<lt>B<View> I<Name>E<gt> block
+
+The packets sent by the Pinba extension include the hostname of the server, the
+server name (the name of the virtual host) and the script that was executed.
+Using B<View> blocks it is possible to separate the data into multiple groups
+to get more meaningful statistics. Each packet is added to all matching groups,
+so that a packet may be accounted for more than once.
+
+=over 4
+
+=item B<Host> I<Host>
+
+Matches the hostname of the system the webserver / script is running on. This
+will contain the result of the L<gethostname(2)> system call. If not
+configured, all hostnames will be accepted.
+
+=item B<Server> I<Server>
+
+Matches the name of the I<virtual host>, i.e. the contents of the
+C<$_SERVER["SERVER_NAME"]> variable when within PHP. If not configured, all
+server names will be accepted.
+
+=item B<Script> I<Script>
+

+=head2 Plugin C<ping>
+
+The I<Ping> plugin starts a new thread which sends ICMP "ping" packets to the
+configured hosts periodically and measures the network latency. Whenever the
+C<read> function of the plugin is called, it submits the average latency, the
+standard deviation and the drop rate for each host.
+
+Available configuration options:
+
+=over 4
+
+=item B<Host> I<IP-address>
+
+Host to ping periodically. This option may be repeated several times to ping
+multiple hosts.
+
+=item B<Interval> I<Seconds>
+
+Sets the interval in which to send ICMP echo packets to the configured hosts.
+This is B<not> the interval in which statistics are queries from the plugin but
+the interval in which the hosts are "pinged". Therefore, the setting here
+should be smaller than or equal to the global B<Interval> setting. Fractional
+times, such as "1.24" are allowed.
+
+Default: B<1.0>
+
+=item B<Timeout> I<Seconds>
+
+Time to wait for a response from the host to which an ICMP packet had been
+sent. If a reply was not received after I<Seconds> seconds, the host is assumed
+to be down or the packet to be dropped. This setting must be smaller than the
+B<Interval> setting above for the plugin to work correctly. Fractional
+arguments are accepted.
+
+Default: B<0.9>
+
+=item B<TTL> I<0-255>
+
+Sets the Time-To-Live of generated ICMP packets.
+
+=item B<SourceAddress> I<host>
+
+Sets the source address to use. I<host> may either be a numerical network
+address or a network hostname.
+
+=item B<Device> I<name>
+
+Sets the outgoing network device to be used. I<name> has to specify an
+interface name (e.E<nbsp>g. C<eth0>). This might not be supported by all
+operating systems.
+
+=item B<MaxMissed> I<Packets>
+
+Trigger a DNS resolve after the host has not replied to I<Packets> packets. This
+enables the use of dynamic DNS services (like dyndns.org) with the ping plugin.
+
+Default: B<-1> (disabled)
+
+=back
+
+=head2 Plugin C<postgresql>
+
+The C<postgresql> plugin queries statistics from PostgreSQL databases. It
+keeps a persistent connection to all configured databases and tries to
+reconnect if the connection has been interrupted. A database is configured by
+specifying a B<Database> block as described below. The default statistics are
+collected from PostgreSQL's B<statistics collector> which thus has to be
+enabled for this plugin to work correctly. This should usually be the case by
+default. See the section "The Statistics Collector" of the B<PostgreSQL
+Documentation> for details.
+
+By specifying custom database queries using a B<Query> block as described
+below, you may collect any data that is available from some PostgreSQL
+database. This way, you are able to access statistics of external daemons
+which are available in a PostgreSQL database or use future or special
+statistics provided by PostgreSQL without the need to upgrade your collectd
+installation.
+
+Starting with version 5.2, the C<postgresql> plugin supports writing data to
+PostgreSQL databases as well. This has been implemented in a generic way. You
+need to specify an SQL statement which will then be executed by collectd in
+order to write the data (see below for details). The benefit of that approach
+is that there is no fixed database layout. Rather, the layout may be optimized
+for the current setup.
+
+The B<PostgreSQL Documentation> manual can be found at
+L<http://www.postgresql.org/docs/manuals/>.

+The B<Query> block defines one database query which may later be used by a
+database definition. It accepts a single mandatory argument which specifies
+the name of the query. The names of all queries have to be unique (see the
+B<MinVersion> and B<MaxVersion> options below for an exception to this
+rule). The following configuration options are available to define the query:
+
+In each B<Query> block, there is one or more B<Result> blocks. B<Result>
+blocks define how to handle the values returned from the query. They define
+which column holds which value and how to dispatch that value to the daemon.
+Multiple B<Result> blocks may be used to extract multiple values from a single
+query.
+
+=over 4

+=item B<Statement> I<sql query statement>
+
+Specify the I<sql query statement> which the plugin should execute. The string
+may contain the tokens B<$1>, B<$2>, etc. which are used to reference the
+first, second, etc. parameter. The value of the parameters is specified by the
+B<Param> configuration option - see below for details. To include a literal
+B<$> character followed by a number, surround it with single quotes (B<'>).
+
+Any SQL command which may return data (such as C<SELECT> or C<SHOW>) is

+The returned lines will be handled separately one after another.
+
+=item B<Param> I<hostname>|I<database>|I<username>|I<interval>
+
+Specify the parameters which should be passed to the SQL query. The parameters

+they appear in the configuration file. The value of the parameter is
+determined depending on the value of the B<Param> option as follows:

+
+=item I<instance>
+
+The name of the database plugin instance. See the B<Instance> option of the
+database specification below for details.

+=item I<username>
+
+The username used to connect to the database.

+=item I<interval>
+
+The interval with which this database is queried (as specified by the database
+specific or global B<Interval> options).
+
+=back
+
+Please note that parameters are only supported by PostgreSQL's protocol
+version 3 and above which was introduced in version 7.4 of PostgreSQL.
+
+=item B<Type> I<type>
+
+The I<type> name to be used when dispatching the values. The type describes
+how to handle the data and where to store it. See L<types.db(5)> for more
+details on types and their configuration. The number and type of values (as
+selected by the B<ValuesFrom> option) has to match the type of the given name.
+
+This option is required inside a B<Result> block.
+
+=item B<InstancePrefix> I<prefix>
+
+=item B<InstancesFrom> I<column0> [I<column1> ...]
+
+Specify how to create the "TypeInstance" for each data set (i.E<nbsp>e. line).
+B<InstancePrefix> defines a static prefix that will be prepended to all type
+instances. B<InstancesFrom> defines the column names whose values will be used
+to create the type instance. Multiple values will be joined together using the
+hyphen (C<->) as separation character.
+
+The plugin itself does not check whether or not all built instances are
+different. It is your responsibility to assure that each is unique.
+
+Both options are optional. If none is specified, the type instance will be
+empty.
+
+=item B<ValuesFrom> I<column0> [I<column1> ...]
+
+Names the columns whose content is used as the actual data for the data sets
+that are dispatched to the daemon. How many such columns you need is
+determined by the B<Type> setting as explained above. If you specify too many
+or not enough columns, the plugin will complain about that and no data will be
+submitted to the daemon.
+
+The actual data type, as seen by PostgreSQL, is not that important as long as
+it represents numbers. The plugin will automatically cast the values to the
+right type if it know how to do that. For that, it uses the L<strtoll(3)> and
+L<strtod(3)> functions, so anything supported by those functions is supported
+by the plugin as well.
+
+This option is required inside a B<Result> block and may be specified multiple
+times. If multiple B<ValuesFrom> options are specified, the columns are read
+in the given order.
+
+=item B<MinVersion> I<version>
+
+=item B<MaxVersion> I<version>
+
+Specify the minimum or maximum version of PostgreSQL that this query should be
+used with. Some statistics might only be available with certain versions of
+PostgreSQL. This allows you to specify multiple queries with the same name but
+which apply to different versions, thus allowing you to use the same
+configuration in a heterogeneous environment.
+
+The I<version> has to be specified as the concatenation of the major, minor
+and patch-level versions, each represented as two-decimal-digit numbers. For
+example, version 8.2.3 will become 80203.

+
+This option may be used for database connections which have "writers" assigned
+(see above). If specified, it causes a writer to put several updates into a
+single transaction. This transaction will last for the specified amount of
+time. By default, each update will be executed in a separate transaction. Each
+transaction generates a fair amount of overhead which can, thus, be reduced by
+activating this option. The draw-back is, that data covering the specified
+amount of time will be lost, for example, if a single statement within the
+transaction fails or if the database server crashes.
+
+=item B<Instance> I<name>
+
+Specify the plugin instance name that should be used instead of the database

+you specify the name of the values as used by the PowerDNS servers, e.E<nbsp>g.
+C<dlg-only-drops>, C<answers10-100>.
+
+The method of getting the values differs for B<Server> and B<Recursor> blocks:
+When querying the server a C<SHOW *> command is issued in any case, because
+that's the only way of getting multiple values out of the server at once.
+collectd then picks out the values you have selected. When querying the
+recursor, a command is generated to query exactly these values. So if you
+specify invalid fields when querying the recursor, a syntax error may be
+returned by the daemon and collectd may not collect any values at all.
+
+If no B<Collect> statement is given, the following B<Server> values will be
+collected:

+Please note that up to that point collectd doesn't know what values are
+available on the server and values that are added do not need a change of the
+mechanism so far. However, the values must be mapped to collectd's naming
+scheme, which is done using a lookup table that lists all known values. If
+values are added in the future and collectd does not know about them, you will
+get an error much like this:

+=item B<Node> I<Nodename>
+
+The B<Node> block identifies a new Redis node, that is a new Redis instance
+running in an specified host and port. The name for node is a canonical
+identifier which is used as I<plugin instance>. It is limited to
+64E<nbsp>characters in length.
+
+=item B<Host> I<Hostname>
+
+The B<Host> option is the hostname or IP-address where the Redis instance is
+running on.
+
+=item B<Port> I<Port>
+
+The B<Port> option is the TCP port on which the Redis instance accepts
+connections. Either a service name of a port number may be given. Please note
+that numerical port numbers must be given as a string, too.
+
+=item B<Password> I<Password>
+
+Use I<Password> to authenticate when connecting to I<Redis>.
+
+=item B<Timeout> I<Milliseconds>
+
+The B<Timeout> option set the socket timeout for node response. Since the Redis
+read function is blocking, you should keep this value as low as possible. Keep
+in mind that the sum of all B<Timeout> values for all B<Nodes> should be lower
+than B<Interval> defined globally.

+=head2 Plugin C<rrdcached>
+
+The C<rrdcached> plugin uses the RRDtool accelerator daemon, L<rrdcached(1)>,
+to store values to RRD files in an efficient manner. The combination of the
+C<rrdcached> B<plugin> and the C<rrdcached> B<daemon> is very similar to the
+way the C<rrdtool> plugin works (see below). The added abstraction layer
+provides a number of benefits, though: Because the cache is not within
+C<collectd> anymore, it does not need to be flushed when C<collectd> is to be
+restarted. This results in much shorter (if any) gaps in graphs, especially
+under heavy load. Also, the C<rrdtool> command line utility is aware of the
+daemon so that it can flush values to disk automatically when needed. This
+allows to integrate automated flushing of values into graphing solutions much
+more easily.
+
+There are disadvantages, though: The daemon may reside on a different host, so
+it may not be possible for C<collectd> to create the appropriate RRD files
+anymore. And even if C<rrdcached> runs on the same host, it may run in a
+different base directory, so relative paths may do weird stuff if you're not
+careful.
+
+So the B<recommended configuration> is to let C<collectd> and C<rrdcached> run
+on the same host, communicating via a UNIX domain socket. The B<DataDir>
+setting should be set to an absolute path, so that a changed base directory
+does not result in RRD files being createdE<nbsp>/ expected in the wrong place.
+
+=over 4
+
+=item B<DaemonAddress> I<Address>
+
+Address of the daemon as understood by the C<rrdc_connect> function of the RRD
+library. See L<rrdcached(1)> for details. Example:
+
+  <Plugin "rrdcached">
+    DaemonAddress "unix:/var/run/rrdcached.sock"
+  </Plugin>
+
+=item B<DataDir> I<Directory>
+
+Set the base directory in which the RRD files reside. If this is a relative
+path, it is relative to the working base directory of the C<rrdcached> daemon!
+Use of an absolute path is recommended.
+
+=item B<CreateFiles> B<true>|B<false>
+
+Enables or disables the creation of RRD files. If the daemon is not running
+locally, or B<DataDir> is set to a relative path, this will not work as
+expected. Default is B<true>.
+
+=item B<CreateFilesAsync> B<false>|B<true>
+
+When enabled, new RRD files are enabled asynchronously, using a separate thread
+that runs in the background. This prevents writes to block, which is a problem
+especially when many hundreds of files need to be created at once. However,
+since the purpose of creating the files asynchronously is I<not> to block until
+the file is available, values before the file is available will be discarded.
+When disabled (the default) files are created synchronously, blocking for a
+short while, while the file is being written.

+=item B<StepSize> I<Seconds>
+
+B<Force> the stepsize of newly created RRD-files. Ideally (and per default)
+this setting is unset and the stepsize is set to the interval in which the data
+is collected. Do not use this option unless you absolutely have to for some
+reason. Setting this option may cause problems with the C<snmp plugin>, the
+C<exec plugin> or when the daemon is set up to receive data from other hosts.
+
+=item B<HeartBeat> I<Seconds>
+
+B<Force> the heartbeat of newly created RRD-files. This setting should be unset
+in which case the heartbeat is set to twice the B<StepSize> which should equal
+the interval in which data is collected. Do not set this option unless you have
+a very good reason to do so.
+
+=item B<RRARows> I<NumRows>
+
+The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
+B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
+three times five RRAs, i. e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+  number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels. The
+default is 1200.
+
+=item B<RRATimespan> I<Seconds>
+
+Adds an RRA-timespan, given in seconds. Use this option multiple times to have
+more then one RRA. If this option is never used, the built-in default of (3600,
+86400, 604800, 2678400, 31622400) is used.
+
+For more information on how RRA-sizes are calculated see B<RRARows> above.

+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". The default is 0.1. If unsure, don't set this option.

+is collected. Do not use this option unless you absolutely have to for some
+reason. Setting this option may cause problems with the C<snmp plugin>, the
+C<exec plugin> or when the daemon is set up to receive data from other hosts.
+
+=item B<HeartBeat> I<Seconds>
+
+B<Force> the heartbeat of newly created RRD-files. This setting should be unset
+in which case the heartbeat is set to twice the B<StepSize> which should equal
+the interval in which data is collected. Do not set this option unless you have
+a very good reason to do so.
+
+=item B<RRARows> I<NumRows>
+
+The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
+B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
+three times five RRAs, i.e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+  number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels. The
+default is 1200.
+
+=item B<RRATimespan> I<Seconds>
+
+Adds an RRA-timespan, given in seconds. Use this option multiple times to have
+more then one RRA. If this option is never used, the built-in default of (3600,
+86400, 604800, 2678400, 31622400) is used.
+
+For more information on how RRA-sizes are calculated see B<RRARows> above.
+
+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". The default is 0.1. If unsure, don't set this option.
+I<Factor> must be in the range C<[0.0-1.0)>, i.e. between zero (inclusive) and
+one (exclusive).
+
+=item B<CacheFlush> I<Seconds>
+
+When the C<rrdtool> plugin uses a cache (by setting B<CacheTimeout>, see below)
+it writes all values for a certain RRD-file if the oldest value is older than
+(or equal to) the number of seconds specified. If some RRD-file is not updated
+anymore for some reason (the computer was shut down, the network is broken,
+etc.) some values may still be in the cache. If B<CacheFlush> is set, then the
+entire cache is searched for entries older than B<CacheTimeout> seconds and
+written to disk every I<Seconds> seconds. Since this is kind of expensive and
+does nothing under normal circumstances, this value should not be too small.
+900 seconds might be a good value, though setting this to 7200 seconds doesn't
+normally do much harm either.
+
+=item B<CacheTimeout> I<Seconds>
+
+If this option is set to a value greater than zero, the C<rrdtool plugin> will
+save values in a cache, as described above. Writing multiple values at once
+reduces IO-operations and thus lessens the load produced by updating the files.
+The trade off is that the graphs kind of "drag behind" and that more memory is
+used.
+
+=item B<WritesPerSecond> I<Updates>
+
+When collecting many statistics with collectd and the C<rrdtool> plugin, you
+will run serious performance problems. The B<CacheFlush> setting and the
+internal update queue assert that collectd continues to work just fine even
+under heavy load, but the system may become very unresponsive and slow. This is
+a problem especially if you create graphs from the RRD files on the same
+machine, for example using the C<graph.cgi> script included in the
+C<contrib/collection3/> directory.
+
+This setting is designed for very large setups. Setting this option to a value
+between 25 and 80 updates per second, depending on your hardware, will leave
+the server responsive enough to draw graphs even while all the cached values
+are written to disk. Flushed values, i.E<nbsp>e. values that are forced to disk
+by the B<FLUSH> command, are B<not> effected by this limit. They are still
+written as fast as possible, so that web frontends have up to date data when
+generating graphs.
+
+For example: If you have 100,000 RRD files and set B<WritesPerSecond> to 30
+updates per second, writing all values to disk will take approximately
+56E<nbsp>minutes. Together with the flushing ability that's integrated into
+"collection3" you'll end up with a responsive and fast system, up to date
+graphs and basically a "backup" of your values every hour.
+
+=item B<RandomTimeout> I<Seconds>
+
+When set, the actual timeout for each value is chosen randomly between
+I<CacheTimeout>-I<RandomTimeout> and I<CacheTimeout>+I<RandomTimeout>. The
+intention is to avoid high load situations that appear when many values timeout
+at the same time. This is especially a problem shortly after the daemon starts,
+because all values were added to the internal cache at roughly the same time.
+
+=back
+
+=head2 Plugin C<sensors>
+
+The I<Sensors plugin> uses B<lm_sensors> to retrieve sensor-values. This means
+that all the needed modules have to be loaded and lm_sensors has to be
+configured (most likely by editing F</etc/sensors.conf>. Read
+L<sensors.conf(5)> for details.
+
+The B<lm_sensors> homepage can be found at
+L<http://secure.netroedge.com/~lm78/>.
+
+=over 4
+
+=item B<SensorConfigFile> I<File>
+
+Read the I<lm_sensors> configuration from I<File>. When unset (recommended),
+the library's default will be used.
+
+=item B<Sensor> I<chip-bus-address/type-feature>
+
+Selects the name of the sensor which you want to collect or ignore, depending
+on the B<IgnoreSelected> below. For example, the option "B<Sensor>
+I<it8712-isa-0290/voltage-in1>" will cause collectd to gather data for the
+voltage sensor I<in1> of the I<it8712> on the isa bus at the address 0290.
+
+=item B<IgnoreSelected> I<true>|I<false>
+
+If no configuration if given, the B<sensors>-plugin will collect data from all
+sensors. This may not be practical, especially for uninteresting sensors.
+Thus, you can use the B<Sensor>-option to pick the sensors you're interested
+in. Sometimes, however, it's easier/preferred to collect all sensors I<except> a
+few ones. This option enables you to do that: By setting B<IgnoreSelected> to
+I<true> the effect of B<Sensor> is inverted: All selected sensors are ignored
+and all other sensors are collected.

+ </Plugin>
+
+=over 4
+
+=item B<LogLevel> B<0-5>
+
+The I<sigrok> logging level to pass on to the I<collectd> log, as a number
+between B<0> and B<5> (inclusive). These levels correspond to C<None>,
+C<Errors>, C<Warnings>, C<Informational>, C<Debug >and C<Spew>, respectively.
+The default is B<2> (C<Warnings>). The I<sigrok> log messages, regardless of
+their level, are always submitted to I<collectd> at its INFO log level.
+
+=item E<lt>B<Device> I<Name>E<gt>
+
+A sigrok-supported device, uniquely identified by this section's options. The
+I<Name> is passed to I<collectd> as the I<plugin instance>.
+
+=item B<Driver> I<DriverName>
+
+The sigrok driver to use for this device.
+
+=item B<Conn> I<ConnectionSpec>
+
+If the device cannot be auto-discovered, or more than one might be discovered
+by the driver, I<ConnectionSpec> specifies the connection string to the device.
+It can be of the form of a device path (e.g.E<nbsp>C</dev/ttyUSB2>), or, in
+case of a non-serial USB-connected device, the USB I<VendorID>B<.>I<ProductID>
+separated by a period (e.g.E<nbsp>C<0403.6001>). A USB device can also be
+specified as I<Bus>B<.>I<Address> (e.g.E<nbsp>C<1.41>).
+
+=item B<SerialComm> I<SerialSpec>
+
+For serial devices with non-standard port settings, this option can be used
+to specify them in a form understood by I<sigrok>, e.g.E<nbsp>C<9600/8n1>.
+This should not be necessary; drivers know how to communicate with devices they
+support.
+
+=item B<MinimumInterval> I<Seconds>
+
+Specifies the minimum time between measurement dispatches to I<collectd>, in
+seconds. Since some I<sigrok> supported devices can acquire measurements many
+times per second, it may be necessary to throttle these. For example, the
+I<RRD plugin> cannot process writes more than once per second.
+
+The default B<MinimumInterval> is B<0>, meaning measurements received from the
+device are always dispatched to I<collectd>. When throttled, unused
+measurements are discarded.
+

+
+=head2 Plugin C<smart>
+
+The C<smart> plugin collects SMART information from physical
+disks. Values collectd include temperature, power cycle count, poweron
+time and bad sectors. Also, all SMART attributes are collected along
+with the normalized current value, the worst value, the threshold and
+a human readable value.
+
+Using the following two options you can ignore some disks or configure the
+collection only of specific disks.
+
+=over 4
+
+=item B<Disk> I<Name>
+
+Select the disk I<Name>. Whether it is collected or ignored depends on the
+B<IgnoreSelected> setting, see below. As with other plugins that use the
+daemon's ignorelist functionality, a string that starts and ends with a slash
+is interpreted as a regular expression. Examples:
+
+  Disk "sdd"
+  Disk "/hda[34]/"
+
+=item B<IgnoreSelected> B<true>|B<false>
+
+Sets whether selected disks, i.E<nbsp>e. the ones matches by any of the B<Disk>
+statements, are ignored or if all other disks are ignored. The behavior
+(hopefully) is intuitive: If no B<Disk> option is configured, all disks are
+collected. If at least one B<Disk> option is given and no B<IgnoreSelected> or
+set to B<false>, B<only> matching disks will be collected. If B<IgnoreSelected>
+is set to B<true>, all disks are collected B<except> the ones matched.

+Since the configuration of the C<snmp plugin> is a little more complicated than
+other plugins, its documentation has been moved to an own manpage,
+L<collectd-snmp(5)>. Please see there for details.
+
+=head2 Plugin C<statsd>
+
+The I<statsd plugin> listens to a UDP socket, reads "events" in the statsd
+protocol and dispatches rates or other aggregates of these numbers
+periodically.
+
+The plugin implements the I<Counter>, I<Timer>, I<Gauge> and I<Set> types which
+are dispatched as the I<collectd> types C<derive>, C<latency>, C<gauge> and
+C<objects> respectively.
+
+The following configuration options are valid:
+
+=over 4
+
+=item B<Host> I<Host>
+
+Bind to the hostname / address I<Host>. By default, the plugin will bind to the
+"any" address, i.e. accept packets sent to any of the hosts addresses.
+
+=item B<Port> I<Port>
+
+UDP port to listen to. This can be either a service name or a port number.
+Defaults to C<8125>.

+
+=item B<DeleteTimers> B<false>|B<true>
+
+=item B<DeleteGauges> B<false>|B<true>
+
+=item B<DeleteSets> B<false>|B<true>
+
+These options control what happens if metrics are not updated in an interval.
+If set to B<False>, the default, metrics are dispatched unchanged, i.e. the
+rate of counters and size of sets will be zero, timers report C<NaN> and gauges
+are unchanged. If set to B<True>, the such metrics are not dispatched and
+removed from the internal cache.
+
+=item B<TimerPercentile> I<Percent>
+
+Calculate and dispatch the configured percentile, i.e. compute the latency, so
+that I<Percent> of all reported timers are smaller than or equal to the
+computed latency. This is useful for cutting off the long tail latency, as it's
+often done in I<Service Level Agreements> (SLAs).
+
+Different percentiles can be calculated by setting this option several times.
+If none are specified, no percentiles are calculated / dispatched.

+
+=item B<TimerUpper> B<false>|B<true>
+
+=item B<TimerSum> B<false>|B<true>
+

+
+The I<Swap plugin> collects information about used and available swap space. On
+I<Linux> and I<Solaris>, the following options are available:
+
+=over 4
+
+=item B<ReportByDevice> B<false>|B<true>
+
+Configures how to report physical swap devices. If set to B<false> (the
+default), the summary over all swap devices is reported only, i.e. the globally
+used and available space over all devices. If B<true> is configured, the used
+and available space of each device will be reported separately.
+
+This option is only available if the I<Swap plugin> can read C</proc/swaps>
+(under Linux) or use the L<swapctl(2)> mechanism (under I<Solaris>).
+
+=item B<ReportBytes> B<false>|B<true>
+
+When enabled, the I<swap I/O> is reported in bytes. When disabled, the default,
+I<swap I/O> is reported in pages. This option is available under Linux only.
+
+=item B<ValuesAbsolute> B<true>|B<false>
+
+Enables or disables reporting of absolute swap metrics, i.e. number of I<bytes>
+available and used. Defaults to B<true>.
+
+=item B<ValuesPercentage> B<false>|B<true>
+
+Enables or disables reporting of relative swap metrics, i.e. I<percent>
+available and free. Defaults to B<false>.
+
+This is useful for deploying I<collectd> in a heterogeneous environment, where
+swap sizes differ and you want to specify generic thresholds or similar.

+syslog-daemon.
+
+Please note that B<debug> is only available if collectd has been compiled with
+debugging support.
+
+=item B<NotifyLevel> B<OKAY>|B<WARNING>|B<FAILURE>
+
+Controls which notifications should be sent to syslog. The default behaviour is
+not to send any. Less severe notifications always imply logging more severe
+notifications: Setting this to B<OKAY> means all notifications will be sent to
+syslog, setting this to B<WARNING> will send B<WARNING> and B<FAILURE>
+notifications but will dismiss B<OKAY> notifications. Setting this option to
+B<FAILURE> will only send failures to syslog.

+
+=head2 Plugin C<table>
+
+The C<table plugin> provides generic means to parse tabular data and dispatch
+user specified values. Values are selected based on column numbers. For
+example, this plugin may be used to get values from the Linux L<proc(5)>
+filesystem or CSV (comma separated values) files.
+
+  <Plugin table>
+    <Table "/proc/slabinfo">
+      Instance "slabinfo"

+        InstancesFrom 0
+        ValuesFrom 4
+      </Result>
+    </Table>
+  </Plugin>
+
+The configuration consists of one or more B<Table> blocks, each of which
+configures one file to parse. Within each B<Table> block, there are one or
+more B<Result> blocks, which configure which data to select and how to
+interpret it.
+
+The following options are available inside a B<Table> block:
+
+=over 4
+
+=item B<Instance> I<instance>
+
+If specified, I<instance> is used as the plugin instance. So, in the above
+example, the plugin name C<table-slabinfo> would be used. If omitted, the
+filename of the table is used instead, with all special characters replaced
+with an underscore (C<_>).
+
+=item B<Separator> I<string>
+
+Any character of I<string> is interpreted as a delimiter between the different
+columns of the table. A sequence of two or more contiguous delimiters in the
+table is considered to be a single delimiter, i.E<nbsp>e. there cannot be any
+empty columns. The plugin uses the L<strtok_r(3)> function to parse the lines
+of a table - see its documentation for more details. This option is mandatory.
+
+A horizontal tab, newline and carriage return may be specified by C<\\t>,
+C<\\n> and C<\\r> respectively. Please note that the double backslashes are
+required because of collectd's config parsing.
+
+=back
+
+The following options are available inside a B<Result> block:
+
+=over 4

+Sets the type used to dispatch the values to the daemon. Detailed information
+about types and their configuration can be found in L<types.db(5)>. This
+option is mandatory.
+
+=item B<InstancePrefix> I<prefix>
+
+If specified, prepend I<prefix> to the type instance. If omitted, only the
+B<InstancesFrom> option is considered for the type instance.
+
+=item B<InstancesFrom> I<column0> [I<column1> ...]
+
+If specified, the content of the given columns (identified by the column
+number starting at zero) will be used to create the type instance for each
+row. Multiple values (and the instance prefix) will be joined together with
+dashes (I<->) as separation character. If omitted, only the B<InstancePrefix>
+option is considered for the type instance.
+
+The plugin itself does not check whether or not all built instances are
+different. It’s your responsibility to assure that each is unique. This is
+especially true, if you do not specify B<InstancesFrom>: B<You> have to make
+sure that the table only contains one row.
+
+If neither B<InstancePrefix> nor B<InstancesFrom> is given, the type instance
+will be empty.
+
+=item B<ValuesFrom> I<column0> [I<column1> ...]
+
+Specifies the columns (identified by the column numbers starting at zero)
+whose content is used as the actual data for the data sets that are dispatched
+to the daemon. How many such columns you need is determined by the B<Type>
+setting above. If you specify too many or not enough columns, the plugin will
+complain about that and no data will be submitted to the daemon. The plugin
+uses L<strtoll(3)> and L<strtod(3)> to parse counter and gauge values
+respectively, so anything supported by those functions is supported by the
+plugin as well. This option is mandatory.

+=head2 Plugin C<tail>
+
+The C<tail plugin> follows logfiles, just like L<tail(1)> does, parses

+        Type "counter"
+        Instance "local_user"
+      </Match>
+    </File>
+  </Plugin>
+
+The config consists of one or more B<File> blocks, each of which configures one
+logfile to parse. Within each B<File> block, there are one or more B<Match>
+blocks, which configure a regular expression to search for.
+
+The B<Instance> option in the B<File> block may be used to set the plugin
+instance. So in the above example the plugin name C<tail-foo> would be used.
+This plugin instance is for all B<Match> blocks that B<follow> it, until the
+next B<Instance> option. This way you can extract several plugin instances from
+one logfile, handy when parsing syslog and the like.
+
+The B<Interval> option allows you to define the length of time between reads. If
+this is not set, the default Interval will be used.
+
+Each B<Match> block has the following options to describe how the match should
+be performed:
+
+=over 4
+
+=item B<Regex> I<regex>
+
+Sets the regular expression to use for matching against a line. The first
+subexpression has to match something that can be turned into a number by
+L<strtoll(3)> or L<strtod(3)>, depending on the value of C<CounterAdd>, see
+below. Because B<extended> regular expressions are used, you do not need to use
+backslashes for subexpressions! If in doubt, please consult L<regex(7)>. Due to
+collectd's config parsing you need to escape backslashes, though. So if you
+want to match literal parentheses you need to do the following:
+
+  Regex "SPAM \\(Score: (-?[0-9]+\\.[0-9]+)\\)"
+
+=item B<ExcludeRegex> I<regex>
+
+Sets an optional regular expression to use for excluding lines from the match.

+
+=back
+
+As you'd expect the B<Gauge*> types interpret the submatch as a floating point
+number, using L<strtod(3)>. The B<Counter*> and B<AbsoluteSet> types interpret

+You have to specify the port in numeric form, so for the mailserver example
+you'd need to set B<25>.
+
+=item B<RemotePort> I<Port>
+
+Count the connections to a specific remote port. This is useful to see how
+much a remote service is used. This is most useful if you want to know how many
+connections a local service has opened to remote services, e.E<nbsp>g. how many
+connections a mail server or news server has to other mail or news servers, or

+
+B<uuid> means use the guest's UUID. This is useful if you want to track the
+same guest across migrations.
+
+B<hostname> means to use the global B<Hostname> setting, which is probably not
+useful on its own because all guests will appear to have the same name.
+
+You can also specify combinations of these fields. For example B<name uuid>
+means to concatenate the guest name and UUID (with a literal colon character
+between, thus I<"foo:1234-1234-1234-1234">).

+the hypervisor (the "dev" property of the target node), which is equal to
+setting B<name>.
+
+B<address> means use the interface's mac address. This is useful since the
+interface path might change between reboots of a guest or across migrations.

+need to apply the patches and compile your own kernel, which will then provide
+the F</proc/virtual> filesystem that is required by this plugin.
+
+The B<VServer> homepage can be found at L<http://linux-vserver.org/>.
+
+B<Note>: The traffic collected by this plugin accounts for the amount of
+traffic passing a socket which might be a lot less than the actual on-wire
+traffic (e.E<nbsp>g. due to headers and retransmission). If you want to
+collect on-wire traffic you could, for example, use the logging facilities of

+block, the following options are available:
+
+=over 4
+
+=item B<URL> I<URL>
+
+URL to which the values are submitted to. Mandatory.
+
+=item B<User> I<Username>
+
+Optional user name needed for authentication.
+
+=item B<Password> I<Password>
+
+Optional password needed for authentication.
+
+=item B<VerifyPeer> B<true>|B<false>
+
+Enable or disable peer SSL certificate verification. See
+L<http://curl.haxx.se/docs/sslcerts.html> for details. Enabled by default.
+
+=item B<VerifyHost> B<true|false>
+
+Enable or disable peer host name verification. If enabled, the plugin checks if
+the C<Common Name> or a C<Subject Alternate Name> field of the SSL certificate
+matches the host name provided by the B<URL> option. If this identity check
+fails, the connection is aborted. Obviously, only works when connecting to a
+SSL enabled server. Enabled by default.
+
+=item B<CACert> I<File>
+
+File that holds one or more SSL certificates. If you want to use HTTPS you will
+possibly need this option. What CA certificates come bundled with C<libcurl>
+and are checked by default depends on the distribution you use.
+
+=item B<CAPath> I<Directory>
+
+Directory holding one or more CA certificate files. You can use this if for
+some reason all the needed CA certificates aren't in the same file and can't be
+pointed to using the B<CACert> option. Requires C<libcurl> to be built against
+OpenSSL.
+
+=item B<ClientKey> I<File>
+
+File that holds the private key in PEM format to be used for certificate-based
+authentication.
+
+=item B<ClientCert> I<File>
+
+File that holds the SSL certificate to be used for certificate-based
+authentication.
+
+=item B<ClientKeyPass> I<Password>
+
+Password required to load the private key in B<ClientKey>.
+
+=item B<SSLVersion> B<SSLv2>|B<SSLv3>|B<TLSv1>|B<TLSv1_0>|B<TLSv1_1>|B<TLSv1_2>

+attempt to figure out the remote SSL protocol version. See
+L<curl_easy_setopt(3)> for more details.
+
+=item B<Format> B<Command>|B<JSON>
+
+Format of the output to generate. If set to B<Command>, will create output that
+is understood by the I<Exec> and I<UnixSock> plugins. When set to B<JSON>, will
+create output in the I<JavaScript Object Notation> (JSON).
+
+Defaults to B<Command>.
+
+=item B<StoreRates> B<true|false>
+
+If set to B<true>, convert counter values to rates. If set to B<false> (the
+default) counter values are stored as is, i.e. as an increasing integer number.
+
+=item B<BufferSize> I<Bytes>
+
+Sets the send buffer size to I<Bytes>. By increasing this buffer, less HTTP
+requests will be generated, but more metrics will be batched / metrics are
+cached for longer before being sent, introducing additional delay until they
+are available on the server side. I<Bytes> must be at least 1024 and cannot
+exceed the size of an C<int>, i.e. 2E<nbsp>GByte.
+Defaults to C<4096>.
+
+=item B<LowSpeedLimit> I<Bytes per Second>
+
+Sets the minimal transfer rate in I<Bytes per Second> below which the
+connection with the HTTP server will be considered too slow and aborted. All
+the data submitted over this connection will probably be lost. Defaults to 0,
+which means no minimum transfer rate is enforced.
+
+=item B<Timeout> I<Timeout>
+
+Sets the maximum time in milliseconds given for HTTP POST operations to
+complete. When this limit is reached, the POST operation will be aborted, and
+all the data in the current send buffer will probably be lost. Defaults to 0,
+which means the connection never times out.
+
+The C<write_http> plugin regularly submits the collected values to the HTTP
+server. How frequently this happens depends on how much data you are collecting
+and the size of B<BufferSize>. The optimal value to set B<Timeout> to is
+slightly below this interval, which you can estimate by monitoring the network
+traffic between collectd and the HTTP server.

+
+=item B<Key> I<String>
+
+Use the specified string as a partioning key for the topic. Kafka breaks
+topic into partitions and guarantees that for a given topology, the same
+consumer will be used for a specific key. The special (case insensitive)
+string B<Random> can be used to specify that an arbitrary partition should
+be used.
+
+=item B<Format> B<Command>|B<JSON>|B<Graphite>
+
+Selects the format in which messages are sent to the broker. If set to
+B<Command> (the default), values are sent as C<PUTVAL> commands which are
+identical to the syntax used by the I<Exec> and I<UnixSock plugins>.
+
+If set to B<JSON>, the values are encoded in the I<JavaScript Object Notation>,
+an easy and straight forward exchange format.
+
+If set to B<Graphite>, values are encoded in the I<Graphite> format, which is
+C<E<lt>metricE<gt> E<lt>valueE<gt> E<lt>timestampE<gt>\n>.
+
+=item B<StoreRates> B<true>|B<false>
+
+Determines whether or not C<COUNTER>, C<DERIVE> and C<ABSOLUTE> data sources
+are converted to a I<rate> (i.e. a C<GAUGE> value). If set to B<false> (the
+default), no conversion is performed. Otherwise the conversion is performed

+=head1 THRESHOLD CONFIGURATION
+
+Starting with version C<4.3.0> collectd has support for B<monitoring>. By that
+we mean that the values are not only stored or sent somewhere, but that they
+are judged and, if a problem is recognized, acted upon. The only action
+collectd takes itself is to generate and dispatch a "notification". Plugins can
+register to receive notifications and perform appropriate further actions.
+
+Since systems and what you expect them to do differ a lot, you can configure
+B<thresholds> for your values freely. This gives you a lot of flexibility but
+also a lot of responsibility.
+
+Every time a value is out of range a notification is dispatched. This means
+that the idle percentage of your CPU needs to be less then the configured
+threshold only once for a notification to be generated. There's no such thing
+as a moving average or similar - at least not now.
+
+Also, all values that match a threshold are considered to be relevant or
+"interesting". As a consequence collectd will issue a notification if they are
+not received for B<Timeout> iterations. The B<Timeout> configuration option is
+explained in section L<"GLOBAL OPTIONS">. If, for example, B<Timeout> is set to
+"2" (the default) and some hosts sends it's CPU statistics to the server every
+60 seconds, a notification will be dispatched after about 120 seconds. It may
+take a little longer because the timeout is checked only once each B<Interval>
+on the server.
+
+When a value comes within range again or is received after it was missing, an
+"OKAY-notification" is dispatched.
+
+Here is a configuration example to get you started. Read below for more
+information.
+
+ <Plugin threshold>
+   <Type "foo">
+     WarningMin    0.00
+     WarningMax 1000.00
+     FailureMin    0.00
+     FailureMax 1200.00

+         WarningMin 100000000
+       </Type>
+     </Plugin>
+   </Host>
+ </Plugin>
+
+There are basically two types of configuration statements: The C<Host>,
+C<Plugin>, and C<Type> blocks select the value for which a threshold should be
+configured. The C<Plugin> and C<Type> blocks may be specified further using the
+C<Instance> option. You can combine the block by nesting the blocks, though
+they must be nested in the above order, i.E<nbsp>e. C<Host> may contain either
+C<Plugin> and C<Type> blocks, C<Plugin> may only contain C<Type> blocks and
+C<Type> may not contain other blocks. If multiple blocks apply to the same
+value the most specific block is used.
+
+The other statements specify the threshold to configure. They B<must> be
+included in a C<Type> block. Currently the following statements are recognized:
+
+=over 4
+
+=item B<FailureMax> I<Value>
+

+
+Sets the upper bound of acceptable values. If unset defaults to positive
+infinity. If a value is greater than B<FailureMax> a B<FAILURE> notification
+will be created. If the value is greater than B<WarningMax> but less than (or
+equal to) B<FailureMax> a B<WARNING> notification will be created.
+
+=item B<FailureMin> I<Value>
+
+=item B<WarningMin> I<Value>
+
+Sets the lower bound of acceptable values. If unset defaults to negative
+infinity. If a value is less than B<FailureMin> a B<FAILURE> notification will
+be created. If the value is less than B<WarningMin> but greater than (or equal
+to) B<FailureMin> a B<WARNING> notification will be created.
+
+=item B<DataSource> I<DSName>
+
+Some data sets have more than one "data source". Interesting examples are the
+C<if_octets> data set, which has received (C<rx>) and sent (C<tx>) bytes and
+the C<disk_ops> data set, which holds C<read> and C<write> operations. The
+system load data set, C<load>, even has three data sources: C<shortterm>,
+C<midterm>, and C<longterm>.
+
+Normally, all data sources are checked against a configured threshold. If this
+is undesirable, or if you want to specify different limits for each data
+source, you can use the B<DataSource> option to have a threshold apply only to
+one data source.
+
+=item B<Invert> B<true>|B<false>
+
+If set to B<true> the range of acceptable values is inverted, i.E<nbsp>e.
+values between B<FailureMin> and B<FailureMax> (B<WarningMin> and
+B<WarningMax>) are not okay. Defaults to B<false>.
+
+=item B<Persist> B<true>|B<false>
+
+Sets how often notifications are generated. If set to B<true> one notification
+will be generated for each value that is out of the acceptable range. If set to
+B<false> (the default) then a notification is only generated if a value is out
+of range but the previous value was okay.
+
+This applies to missing values, too: If set to B<true> a notification about a
+missing value is generated once every B<Interval> seconds. If set to B<false>
+only one such notification is generated until the value appears again.
+
+=item B<Percentage> B<true>|B<false>
+
+If set to B<true>, the minimum and maximum values given are interpreted as
+percentage value, relative to the other data sources. This is helpful for
+example for the "df" type, where you may want to issue a warning when less than
+5E<nbsp>% of the total space is available. Defaults to B<false>.
+
+=item B<Hits> I<Number>
+
+Delay creating the notification until the threshold has been passed I<Number>
+times. When a notification has been generated, or when a subsequent value is
+inside the threshold, the counter is reset. If, for example, a value is
+collected once every 10E<nbsp>seconds and B<Hits> is set to 3, a notification
+will be dispatched at most once every 30E<nbsp>seconds.
+
+This is useful when short bursts are not a problem. If, for example, 100% CPU
+usage for up to a minute is normal (and data is collected every
+10E<nbsp>seconds), you could set B<Hits> to B<6> to account for this.
+
+=item B<Hysteresis> I<Number>
+
+When set to non-zero, a hysteresis value is applied when checking minimum and
+maximum bounds. This is useful for values that increase slowly and fluctuate a
+bit while doing so. When these values come close to the threshold, they may
+"flap", i.e. switch between failure / warning case and okay case repeatedly.
+
+If, for example, the threshold is configures as
+
+  WarningMax 100.0
+  Hysteresis 1.0
+
+then a I<Warning> notification is created when the value exceeds I<101> and the
+corresponding I<Okay> notification is only created once the value falls below
+I<99>, thus avoiding the "flapping".

+=head1 FILTER CONFIGURATION
+
+Starting with collectd 4.6 there is a powerful filtering infrastructure
+implemented in the daemon. The concept has mostly been copied from
+I<ip_tables>, the packet filter infrastructure for Linux. We'll use a similar
+terminology, so that users that are familiar with iptables feel right at home.
+
+=head2 Terminology
+
+The following are the terms used in the remainder of the filter configuration
+documentation. For an ASCII-art schema of the mechanism, see
+L<"General structure"> below.
+
+=over 4
+
+=item B<Match>
+
+A I<match> is a criteria to select specific values. Examples are, of course, the
+name of the value or it's current value.
+
+Matches are implemented in plugins which you have to load prior to using the
+match. The name of such plugins starts with the "match_" prefix.
+
+=item B<Target>
+
+A I<target> is some action that is to be performed with data. Such actions
+could, for example, be to change part of the value's identifier or to ignore
+the value completely.
+
+Some of these targets are built into the daemon, see L<"Built-in targets">
+below. Other targets are implemented in plugins which you have to load prior to
+using the target. The name of such plugins starts with the "target_" prefix.
+
+=item B<Rule>
+
+The combination of any number of matches and at least one target is called a
+I<rule>. The target actions will be performed for all values for which B<all>
+matches apply. If the rule does not have any matches associated with it, the
+target action will be performed for all values.
+
+=item B<Chain>
+
+A I<chain> is a list of rules and possibly default targets. The rules are tried
+in order and if one matches, the associated target will be called. If a value
+is handled by a rule, it depends on the target whether or not any subsequent
+rules are considered or if traversal of the chain is aborted, see
+L<"Flow control"> below. After all rules have been checked, the default targets
+will be executed.
+
+=back
+

+=head2 Flow control
+
+There are four ways to control which way a value takes through the filter
+mechanism:
+
+=over 4
+
+=item B<jump>
+
+The built-in B<jump> target can be used to "call" another chain, i.E<nbsp>e.
+process the value with another chain. When the called chain finishes, usually
+the next target or rule after the jump is executed.
+
+=item B<stop>
+
+The stop condition, signaled for example by the built-in target B<stop>, causes
+all processing of the value to be stopped immediately.
+
+=item B<return>
+
+Causes processing in the current chain to be aborted, but processing of the
+value generally will continue. This means that if the chain was called via
+B<Jump>, the next target or rule after the jump will be executed. If the chain
+was not called by another chain, control will be returned to the daemon and it
+may pass the value to another chain.
+
+=item B<continue>
+
+Most targets will signal the B<continue> condition, meaning that processing
+should continue normally. There is no special built-in target for this
+condition.
+
+=back
+
+=head2 Synopsis
+
+The configuration reflects this structure directly:
+
+ PostCacheChain "PostCache"
+ <Chain "PostCache">
+   <Rule "ignore_mysql_show">
+     <Match "regex">
+       Plugin "^mysql$"
+       Type "^mysql_command$"
+       TypeInstance "^show_"
+     </Match>
+     <Target "stop">
+     </Target>
+   </Rule>
+   <Target "write">
+     Plugin "rrdtool"
+   </Target>
+ </Chain>
+
+The above configuration example will ignore all values where the plugin field
+is "mysql", the type is "mysql_command" and the type instance begins with
+"show_". All other values will be sent to the C<rrdtool> write plugin via the
+default target of the chain. Since this chain is run after the value has been
+added to the cache, the MySQL C<show_*> command statistics will be available
+via the C<unixsock> plugin.
+
+=head2 List of configuration options
+
+=over 4
+
+=item B<PreCacheChain> I<ChainName>
+
+=item B<PostCacheChain> I<ChainName>
+
+Configure the name of the "pre-cache chain" and the "post-cache chain". The
+argument is the name of a I<chain> that should be executed before and/or after
+the values have been added to the cache.
+
+To understand the implications, it's important you know what is going on inside
+I<collectd>. The following diagram shows how values are passed from the
+read-plugins to the write-plugins:
+
+   +---------------+
+   !  Read-Plugin  !
+   +-------+-------+
+           !
+ + - - - - V - - - - +
+ : +---------------+ :

+ : !     Cache     !--->!  Value Cache  !
+ : !     insert    ! :  +---+---+-------+
+ : +-------+-------+ :      !   !
+ :         !   ,------------'   !
+ :         V   V     :          V
+ : +-------+---+---+ :  +-------+-------+
+ : !  Post-Cache   +--->! Write-Plugins !
+ : !     Chain     ! :  +---------------+
+ : +---------------+ :
+ :                   :
+ :  dispatch values  :
+ + - - - - - - - - - +
+
+After the values are passed from the "read" plugins to the dispatch functions,
+the pre-cache chain is run first. The values are added to the internal cache
+afterwards. The post-cache chain is run after the values have been added to the
+cache. So why is it such a huge deal if chains are run before or after the
+values have been added to this cache?
+
+Targets that change the identifier of a value list should be executed before
+the values are added to the cache, so that the name in the cache matches the
+name that is used in the "write" plugins. The C<unixsock> plugin, too, uses
+this cache to receive a list of all available values. If you change the
+identifier after the value list has been added to the cache, this may easily
+lead to confusion, but it's not forbidden of course.
+
+The cache is also used to convert counter values to rates. These rates are, for
+example, used by the C<value> match (see below). If you use the rate stored in
+the cache B<before> the new value is added, you will use the old, B<previous>
+rate. Write plugins may use this rate, too, see the C<csv> plugin, for example.
+The C<unixsock> plugin uses these rates too, to implement the C<GETVAL>
+command.
+
+Last but not last, the B<stop> target makes a difference: If the pre-cache
+chain returns the stop condition, the value will not be added to the cache and
+the post-cache chain will not be run.
+
+=item B<Chain> I<Name>
+
+Adds a new chain with a certain name. This name can be used to refer to a
+specific chain, for example to jump to it.
+
+Within the B<Chain> block, there can be B<Rule> blocks and B<Target> blocks.
+
+=item B<Rule> [I<Name>]
+
+Adds a new rule to the current chain. The name of the rule is optional and
+currently has no meaning for the daemon.
+
+Within the B<Rule> block, there may be any number of B<Match> blocks and there
+must be at least one B<Target> block.
+
+=item B<Match> I<Name>
+
+Adds a match to a B<Rule> block. The name specifies what kind of match should
+be performed. Available matches depend on the plugins that have been loaded.
+
+The arguments inside the B<Match> block are passed to the plugin implementing
+the match, so which arguments are valid here depends on the plugin being used.
+If you do not need any to pass any arguments to a match, you can use the
+shorter syntax:
+
+ Match "foobar"
+
+Which is equivalent to:
+
+ <Match "foobar">
+ </Match>
+
+=item B<Target> I<Name>
+
+Add a target to a rule or a default target to a chain. The name specifies what
+kind of target is to be added. Which targets are available depends on the
+plugins being loaded.
+
+The arguments inside the B<Target> block are passed to the plugin implementing
+the target, so which arguments are valid here depends on the plugin being used.
+If you do not need any to pass any arguments to a target, you can use the
+shorter syntax:
+
+ Target "stop"
+
+This is the same as writing:
+
+ <Target "stop">
+ </Target>
+
+=back
+
+=head2 Built-in targets
+
+The following targets are built into the core daemon and therefore need no
+plugins to be loaded:
+
+=over 4
+
+=item B<return>
+
+Signals the "return" condition, see the L<"Flow control"> section above. This
+causes the current chain to stop processing the value and returns control to
+the calling chain. The calling chain will continue processing targets and rules
+just after the B<jump> target (see below). This is very similar to the
+B<RETURN> target of iptables, see L<iptables(8)>.
+
+This target does not have any options.
+
+Example:
+
+ Target "return"
+
+=item B<stop>
+
+Signals the "stop" condition, see the L<"Flow control"> section above. This
+causes processing of the value to be aborted immediately. This is similar to
+the B<DROP> target of iptables, see L<iptables(8)>.
+
+This target does not have any options.
+
+Example:
+
+ Target "stop"
+
+=item B<write>
+
+Sends the value to "write" plugins.
+
+Available options:
+
+=over 4
+
+=item B<Plugin> I<Name>
+
+Name of the write plugin to which the data should be sent. This option may be
+given multiple times to send the data to more than one write plugin. If the
+plugin supports multiple instances, the plugin's instance(s) must also be
+specified.
+
+=back
+
+If no plugin is explicitly specified, the values will be sent to all available
+write plugins.
+
+Single-instance plugin example:
+
+ <Target "write">
+   Plugin "rrdtool"
+ </Target>
+
+Multi-instance plugin example:
+
+ <Plugin "write_graphite">
+   <Node "foo">
+   ...
+   </Node>
+   <Node "bar">
+   ...
+   </Node>
+ </Plugin>
+  ...
+ <Target "write">
+   Plugin "write_graphite/foo"
+ </Target>
+
+=item B<jump>
+
+Starts processing the rules of another chain, see L<"Flow control"> above. If
+the end of that chain is reached, or a stop condition is encountered,
+processing will continue right after the B<jump> target, i.E<nbsp>e. with the
+next target or the next rule. This is similar to the B<-j> command line option
+of iptables, see L<iptables(8)>.
+
+Available options:

+regexen must match for a value to match.
+
+=item B<Invert> B<false>|B<true>
+
+When set to B<true>, the result of the match is inverted, i.e. all value lists
+where all regular expressions apply are not matched, all other value lists are
+matched. Defaults to B<false>.

+
+Example:
+
+ <Match "regex">
+   Host "customer[0-9]+"
+   Plugin "^foobar$"
+ </Match>
+
+=item B<timediff>
+
+Matches values that have a time which differs from the time on the server.
+
+This match is mainly intended for servers that receive values over the
+C<network> plugin and write them to disk using the C<rrdtool> plugin. RRDtool
+is very sensitive to the timestamp used when updating the RRD files. In
+particular, the time must be ever increasing. If a misbehaving client sends one
+packet with a timestamp far in the future, all further packets with a correct
+time will be ignored because of that one packet. What's worse, such corrupted
+RRD files are hard to fix.
+
+This match lets one match all values B<outside> a specified time range
+(relative to the server's time), so you can use the B<stop> target (see below)
+to ignore the value, for example.
+
+Available options:
+
+=over 4
+
+=item B<Future> I<Seconds>
+
+Matches all values that are I<ahead> of the server's time by I<Seconds> or more
+seconds. Set to zero for no limit. Either B<Future> or B<Past> must be
+non-zero.
+
+=item B<Past> I<Seconds>
+
+Matches all values that are I<behind> of the server's time by I<Seconds> or
+more seconds. Set to zero for no limit. Either B<Future> or B<Past> must be
+non-zero.
+
+=back
+
+Example:
+
+ <Match "timediff">
+   Future  300
+   Past   3600
+ </Match>
+
+This example matches all values that are five minutes or more ahead of the
+server or one hour (or more) lagging behind.
+
+=item B<value>
+
+Matches the actual value of data sources against given minimumE<nbsp>/ maximum
+values. If a data-set consists of more than one data-source, all data-sources
+must match the specified ranges for a positive match.
+
+Available options:
+
+=over 4
+
+=item B<Min> I<Value>
+
+Sets the smallest value which still results in a match. If unset, behaves like
+negative infinity.
+
+=item B<Max> I<Value>
+
+Sets the largest value which still results in a match. If unset, behaves like
+positive infinity.
+
+=item B<Invert> B<true>|B<false>
+
+Inverts the selection. If the B<Min> and B<Max> settings result in a match,
+no-match is returned and vice versa. Please note that the B<Invert> setting
+only effects how B<Min> and B<Max> are applied to a specific value. Especially
+the B<DataSource> and B<Satisfy> settings (see below) are not inverted.
+
+=item B<DataSource> I<DSName> [I<DSName> ...]
+
+Select one or more of the data sources. If no data source is configured, all
+data sources will be checked. If the type handled by the match does not have a
+data source of the specified name(s), this will always result in no match
+(independent of the B<Invert> setting).
+
+=item B<Satisfy> B<Any>|B<All>
+
+Specifies how checking with several data sources is performed. If set to
+B<Any>, the match succeeds if one of the data sources is in the configured
+range. If set to B<All> the match only succeeds if all data sources are within
+the configured range. Default is B<All>.
+
+Usually B<All> is used for positive matches, B<Any> is used for negative
+matches. This means that with B<All> you usually check that all values are in a
+"good" range, while with B<Any> you check if any value is within a "bad" range
+(or outside the "good" range).
+
+=back
+
+Either B<Min> or B<Max>, but not both, may be unset.
+
+Example:
+
+ # Match all values smaller than or equal to 100. Matches only if all data
+ # sources are below 100.
+ <Match "value">
+   Max 100
+   Satisfy "All"
+ </Match>
+
+ # Match if the value of any data source is outside the range of 0 - 100.
+ <Match "value">
+   Min   0
+   Max 100
+   Invert true
+   Satisfy "Any"
+ </Match>
+
+=item B<empty_counter>
+
+Matches all values with one or more data sources of type B<COUNTER> and where
+all counter values are zero. These counters usually I<never> increased since
+they started existing (and are therefore uninteresting), or got reset recently
+or overflowed and you had really, I<really> bad luck.
+
+Please keep in mind that ignoring such counters can result in confusing
+behavior: Counters which hardly ever increase will be zero for long periods of
+time. If the counter is reset for some reason (machine or service restarted,
+usually), the graph will be empty (NAN) for a long time. People may not
+understand why.
+
+=item B<hashed>
+
+Calculates a hash value of the host name and matches values according to that
+hash value. This makes it possible to divide all hosts into groups and match
+only values that are in a specific group. The intended use is in load
+balancing, where you want to handle only part of all data and leave the rest
+for other servers.
+
+The hashing function used tries to distribute the hosts evenly. First, it
+calculates a 32E<nbsp>bit hash value using the characters of the hostname:
+
+  hash_value = 0;
+  for (i = 0; host[i] != 0; i++)
+    hash_value = (hash_value * 251) + host[i];
+
+The constant 251 is a prime number which is supposed to make this hash value
+more random. The code then checks the group for this host according to the
+I<Total> and I<Match> arguments:
+
+  if ((hash_value % Total) == Match)
+    matches;
+  else
+    does not match;
+
+Please note that when you set I<Total> to two (i.E<nbsp>e. you have only two
+groups), then the least significant bit of the hash value will be the XOR of
+all least significant bits in the host name. One consequence is that when you
+have two hosts, "server0.example.com" and "server1.example.com", where the host
+name differs in one digit only and the digits differ by one, those hosts will
+never end up in the same group.
+
+Available options:
+
+=over 4
+
+=item B<Match> I<Match> I<Total>
+
+Divide the data into I<Total> groups and match all hosts in group I<Match> as
+described above. The groups are numbered from zero, i.E<nbsp>e. I<Match> must
+be smaller than I<Total>. I<Total> must be at least one, although only values
+greater than one really do make any sense.
+
+You can repeat this option to match multiple groups, for example:
+
+  Match 3 7
+  Match 5 7
+
+The above config will divide the data into seven groups and match groups three
+and five. One use would be to keep every value on two hosts so that if one
+fails the missing data can later be reconstructed from the second host.

+
+=item B<Host> I<String>
+
+=item B<Plugin> I<String>
+
+=item B<PluginInstance> I<String>
+
+=item B<TypeInstance> I<String>
+
+Set the appropriate field to the given string. The strings for plugin instance
+and type instance may be empty, the strings for host and plugin may not be
+empty. It's currently not possible to set the type of a value this way.

+
+=head2 Backwards compatibility
+
+If you use collectd with an old configuration, i.E<nbsp>e. one without a
+B<Chain> block, it will behave as it used to. This is equivalent to the
+following configuration:
+
+ <Chain "PostCache">
+   Target "write"
+ </Chain>
+
+If you specify a B<PostCacheChain>, the B<write> target will not be added
+anywhere and you will have to make sure that it is called where appropriate. We
+suggest to add the above snippet as default target to your "PostCache" chain.
+
+=head2 Examples
+
+Ignore all values, where the hostname does not contain a dot, i.E<nbsp>e. can't
+be an FQDN.
+
+ <Chain "PreCache">
+   <Rule "no_fqdn">
+     <Match "regex">
+       Host "^[^\.]*$"
+     </Match>
+     Target "stop"

+=head1 NAME
+
+collectd - System statistics collection daemon
+
+=head1 SYNOPSIS
+
+collectd I<[options]>
+
+=head1 DESCRIPTION
+
+collectd is a daemon that receives system statistics and makes them available
+in a number of ways. The main daemon itself doesn't have any real functionality
+apart from loading, querying and submitting to plugins. For a description of
+available plugins please see L</PLUGINS> below.
+
+=head1 OPTIONS
+
+Most of collectd's configuration is done using using a configfile. See
+L<collectd.conf(5)> for an in-depth description of all options.
+
+=over 4
+
+=item B<-C> I<E<lt>config-fileE<gt>>
+
+Specify an alternative config file. This is the place to go when you wish to
+change B<collectd>'s behavior. The path may be relative to the current working
+directory.
+
+=item B<-t>
+
+Test the configuration only. The program immediately exits after parsing the
+config file. A return code not equal to zero indicates an error.
+
+=item B<-T>
+
+Test the plugin read callbacks only. The program immediately exits after invoking
+the read callbacks once. A return code not equal to zero indicates an error.
+
+=item B<-P> I<E<lt>pid-fileE<gt>>
+
+Specify an alternative pid file. This overwrites any settings in the config 
+file. This is thought for init-scripts that require the PID-file in a certain
+directory to work correctly. For everyday-usage use the B<PIDFile>
+config-option.
+
+=item B<-f>
+
+Don't fork to the background. I<collectd> will also B<not> close standard file
+descriptors, detach from the session nor write a pid file. This is mainly
+thought for 'supervising' init replacements such as I<runit>. If using
+I<upstart> or I<systemd> though, starting with version 5.5.0 I<collectd> is
+able to notify these two init replacements, and B<does> require forking to the
+background for process supervision. The F<contrib/> directory has sample
+I<upstart> and I<systemd> configuration files.
+
+=item B<-h>
+
+Output usage information and exit.
+
+=back
+
+=head1 PLUGINS
+
+As noted above, the real power of collectd lies within it's plugins. A
+(hopefully complete) list of plugins and short descriptions can be found in the
+F<README> file that is distributed with the sourcecode. If you're using a
+package it's a good bet to search somewhere near F</usr/share/doc/collectd>.
+
+There are two big groups of plugins, B<input> and B<output> plugins:
+
+=over 4
+
+=item
+
+Input plugins are queried periodically. They somehow acquire the current value
+of whatever they where designed to work with and submit these values back to
+the daemon, i. e. they "dispatch" the values. As an example, the C<cpu plugin>
+reads the current cpu-counters of time spent in the various modes (user,
+system, nice, ...) and dispatches these counters to the daemon.
+
+=item
+
+Output plugins get the dispatched values from the daemon and does something
+with them. Common applications are writing to RRD-files, CSV-files or sending
+the data over a network link to a remote box.
+
+=back
+
+Of course not all plugins fit neatly into one of the two above categories. The
+C<network plugin>, for example, is able to send (i.E<nbsp>e. "write") B<and>
+receive (i.E<nbsp>e. "dispatch") values. Also, it opens a socket upon
+initialization and dispatches the values when it receives them and isn't
+triggered at the same time the input plugins are being read. You can think of
+the network receive part as working asynchronous if it helps.
+
+In addition to the above, there are "logging plugins". Right now those are the
+C<logfile plugin> and the C<syslog plugin>. With these plugins collectd can
+provide information about issues and significant situations to the user.
+Several loglevels let you suppress uninteresting messages.
+
+Starting with version C<4.3.0> collectd has support for B<monitoring>. This is
+done by checking thresholds defined by the user. If a value is out of range, a
+notification will be dispatched to "notification plugins". See
+L<collectd.conf(5)> for more detailed information about threshold checking.
+
+Please note that some plugins, that provide other means of communicating with
+the daemon, have manpages of their own to describe their functionality in more
+detail. In particular those are L<collectd-email(5)>, L<collectd-exec(5)>,
+L<collectd-perl(5)>, L<collectd-snmp(5)>, and L<collectd-unixsock(5)>
+
+=head1 SIGNALS
+
+B<collectd> accepts the following signals:
+
+=over 4
+
+=item B<SIGINT>, B<SIGTERM>
+
+These signals cause B<collectd> to shut down all plugins and terminate.
+
+=item B<SIGUSR1>
+
+This signal causes B<collectd> to signal all plugins to flush data from
+internal caches. E.E<nbsp>g. the C<rrdtool plugin> will write all pending data
+to the RRD files. This is the same as using the C<FLUSH -1> command of the
+C<unixsock plugin>.

+interact with the daemon using the \f(CW\*(C`unixsock plugin\*(C'\fR.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+collectdctl supports the following options:
+.IP "\fB\-s\fR \fIsocket\fR" 4
+.IX Item "-s socket"
+Path to the \s-1UNIX\s0 socket opened by collectd's \f(CW\*(C`unixsock plugin\*(C'\fR.
+Default: /var/run/collectd\-unixsock
+.IP "\fB\-h\fR" 4
+.IX Item "-h"
+Display usage information and exit.
+.SH "AVAILABLE COMMANDS"
+.IX Header "AVAILABLE COMMANDS"
+The following commands are supported:
+.IP "\fBgetval\fR \fI<identifier>\fR" 4
+.IX Item "getval <identifier>"
+Query the latest collected value identified by the specified
+\&\fI<identifier>\fR (see below). The value-list associated with that
+data-set is returned as a list of key-value-pairs, each on its own line. Keys
+and values are separated by the equal sign (\f(CW\*(C`=\*(C'\fR).
+.IP "\fBflush\fR [\fBtimeout=\fR\fI<seconds>\fR] [\fBplugin=\fR\fI<name>\fR] [\fBidentifier=\fR\fI<id>\fR]" 4
+.IX Item "flush [timeout=<seconds>] [plugin=<name>] [identifier=<id>]"
+Flush the daemon. This is useful, e.\ g., to make sure that the latest
+values have been written to the respective \s-1RRD\s0 file before graphing them or
+copying them to somewhere else.
+.Sp
+The following options are supported by the flush command:
+.RS 4
+.IP "\fBtimeout=\fR\fI<seconds>\fR" 4
+.IX Item "timeout=<seconds>"
+Flush values older than the specified timeout (in seconds) only.
+.IP "\fBplugin=\fR\fI<name>\fR" 4
+.IX Item "plugin=<name>"
+Flush the specified plugin only. I.\ e., data cached by the specified
+plugin is written to disk (or network or whatever), if the plugin supports
+that operation.
+.Sp
+Example: \fBrrdtool\fR.
+.IP "\fBidentifier=\fR\fI<id>\fR" 4
+.IX Item "identifier=<id>"
+If this option is present, only the data specified by the specified identifier
+(see below) will be flushed. Note that this option is not supported by all
+plugins (e.\ g., the \f(CW\*(C`network\*(C'\fR plugin does not support this).
+.RE
+.RS 4
+.Sp
+The \fBplugin\fR and \fBidentifier\fR options may be specified more than once. In
+that case, all combinations of specified plugins and identifiers will be
+flushed only.
+.RE
+.IP "\fBlistval\fR" 4
+.IX Item "listval"
+Returns a list of all values (by their identifier) available to the
+\&\f(CW\*(C`unixsock\*(C'\fR plugin. Each value is printed on its own line. I.\ e., this
+command returns a list of valid identifiers that may be used with the other
+commands.
+.IP "\fBputval\fR \fI<identifier>\fR [\fBinterval=\fR\fI<seconds>\fR] \fI<value\-list(s)>\fR" 4
+.IX Item "putval <identifier> [interval=<seconds>] <value-list(s)>"
+Submit one or more values (identified by \fI<identifier>\fR, see below)
+to the daemon which will then dispatch them to the write plugins. \fBinterval\fR
+specifies the interval (in seconds) used to collect the values following that
+option. It defaults to the default of the running collectd instance receiving
+the data. Multiple \fI<value\-list(s)>\fR (see below) may be specified.
+Each of them will be submitted to the daemon. The values have to match the
+data-set definition specified by the type as given in the identifier (see
+\&\fItypes.db\fR\|(5) for details).
+.SH "IDENTIFIERS"
+.IX Header "IDENTIFIERS"
+An identifier has the following format:
+.PP
+[\fIhostname\fR/]\fIplugin\fR[\-\fIplugin_instance\fR]/\fItype\fR[\-\fItype_instance\fR]
+.PP
+Examples:
+ somehost/cpu\-0/cpu\-idle
+ uptime/uptime
+ otherhost/memory/memory\-used
+.PP
+Hostname defaults to the local (non-fully qualified) hostname if omitted. No
+error is returned if the specified identifier does not exist (this is a
+limitation in the \f(CW\*(C`libcollectdclient\*(C'\fR library).
+.SH "VALUE-LIST"
+.IX Header "VALUE-LIST"
+A value list describes one data-set as handled by collectd. It is a colon
+(\f(CW\*(C`:\*(C'\fR) separated list of the time and the values. Each value is either given
+as an integer if the data-type is a counter, or as a double if the data-type
+is a gauge value. A literal \f(CW\*(C`U\*(C'\fR is interpreted as an undefined gauge value.
+The number of values and the data-types have to match the type specified in
+the identifier (see \fItypes.db\fR\|(5) for details). The time is specified as
+epoch (i.\ e., standard \s-1UNIX\s0 time) or as a literal \f(CW\*(C`N\*(C'\fR which will be
+interpreted as now.
+.SH "EXAMPLES"
+.IX Header "EXAMPLES"
+.ie n .IP """collectdctl flush plugin=rrdtool identifier=somehost/cpu\-0/cpu\-wait""" 4
+.el .IP "\f(CWcollectdctl flush plugin=rrdtool identifier=somehost/cpu\-0/cpu\-wait\fR" 4

+=head1 NAME
+
+collectdctl - Control interface for collectd
+
+=head1 SYNOPSIS
+
+collectdctl I<[options]> I<E<lt>commandE<gt>> I<[command options]>
+
+=head1 DESCRIPTION
+
+collectdctl provides a control interface for collectd, which may be used to
+interact with the daemon using the C<unixsock plugin>.
+
+=head1 OPTIONS
+
+collectdctl supports the following options:
+
+=over 4
+
+=item B<-s> I<socket>
+
+Path to the UNIX socket opened by collectd's C<unixsock plugin>.
+Default: /var/run/collectd-unixsock
+
+=item B<-h>
+
+Display usage information and exit.
+
+=back
+
+=head1 AVAILABLE COMMANDS
+
+The following commands are supported:
+
+=over 4
+
+=item B<getval> I<E<lt>identifierE<gt>>
+
+Query the latest collected value identified by the specified
+I<E<lt>identifierE<gt>> (see below). The value-list associated with that
+data-set is returned as a list of key-value-pairs, each on its own line. Keys
+and values are separated by the equal sign (C<=>).
+
+=item B<flush> [B<timeout=>I<E<lt>secondsE<gt>>] [B<plugin=>I<E<lt>nameE<gt>>]
+[B<identifier=>I<E<lt>idE<gt>>]
+
+Flush the daemon. This is useful, e.E<nbsp>g., to make sure that the latest
+values have been written to the respective RRD file before graphing them or
+copying them to somewhere else.
+
+The following options are supported by the flush command:
+
+=over 4
+
+=item B<timeout=>I<E<lt>secondsE<gt>>
+
+Flush values older than the specified timeout (in seconds) only.
+
+=item B<plugin=>I<E<lt>nameE<gt>>
+
+Flush the specified plugin only. I.E<nbsp>e., data cached by the specified
+plugin is written to disk (or network or whatever), if the plugin supports
+that operation.
+
+Example: B<rrdtool>.
+
+=item B<identifier=>I<E<lt>idE<gt>>
+
+If this option is present, only the data specified by the specified identifier
+(see below) will be flushed. Note that this option is not supported by all
+plugins (e.E<nbsp>g., the C<network> plugin does not support this).
+
+=back
+
+The B<plugin> and B<identifier> options may be specified more than once. In
+that case, all combinations of specified plugins and identifiers will be
+flushed only.
+
+=item B<listval>
+
+Returns a list of all values (by their identifier) available to the
+C<unixsock> plugin. Each value is printed on its own line. I.E<nbsp>e., this
+command returns a list of valid identifiers that may be used with the other
+commands.
+
+=item B<putval> I<E<lt>identifierE<gt>> [B<interval=>I<E<lt>secondsE<gt>>]
+I<E<lt>value-list(s)E<gt>>
+
+Submit one or more values (identified by I<E<lt>identifierE<gt>>, see below)
+to the daemon which will then dispatch them to the write plugins. B<interval>
+specifies the interval (in seconds) used to collect the values following that
+option. It defaults to the default of the running collectd instance receiving
+the data. Multiple I<E<lt>value-list(s)E<gt>> (see below) may be specified.
+Each of them will be submitted to the daemon. The values have to match the
+data-set definition specified by the type as given in the identifier (see
+L<types.db(5)> for details).
+

+

+
+An identifier has the following format:

+[I<hostname>/]I<plugin>[-I<plugin_instance>]/I<type>[-I<type_instance>]
+
+Examples:
+ somehost/cpu-0/cpu-idle
+ uptime/uptime
+ otherhost/memory/memory-used
+
+Hostname defaults to the local (non-fully qualified) hostname if omitted. No
+error is returned if the specified identifier does not exist (this is a
+limitation in the C<libcollectdclient> library).
+
+=head1 VALUE-LIST
+
+A value list describes one data-set as handled by collectd. It is a colon
+(C<:>) separated list of the time and the values. Each value is either given
+as an integer if the data-type is a counter, or as a double if the data-type
+is a gauge value. A literal C<U> is interpreted as an undefined gauge value.
+The number of values and the data-types have to match the type specified in
+the identifier (see L<types.db(5)> for details). The time is specified as
+epoch (i.E<nbsp>e., standard UNIX time) or as a literal C<N> which will be
+interpreted as now.
+
+=head1 EXAMPLES
+
+=over 4
+
+=item C<collectdctl flush plugin=rrdtool identifier=somehost/cpu-0/cpu-wait>
+
+Flushes all CPU wait RRD values of the first CPU of the local host.
+I.E<nbsp>e., writes all pending RRD updates of that data-source to disk.
+
+=item C<for ident in `collectdctl listval | grep users/users`; do
+      collectdctl getval $ident;
+  done>
+
+Query the latest number of logged in users on all hosts known to the local
+collectd instance.

+.IX Header "OPTIONS"
+collectdmon supports the following options:
+.IP "\fB\-c\fR \fI<path>\fR" 4
+.IX Item "-c <path>"
+Specify the pathname of the collectd binary. You may either specify an
+absolute path or simply the name of the binary in which case the \fB\s-1PATH\s0\fR
+variable will be searched for it. The default is "\fBcollectd\fR".
+.IP "\fB\-P\fR \fI<pid\-file>\fR" 4
+.IX Item "-P <pid-file>"
+Specify the pid file. The default is "\fI/var/run/collectdmon.pid\fR".
+.IP "\fB\-h\fR" 4
+.IX Item "-h"
+Output usage information and exit.
+.IP "\fIcollectd options\fR" 4
+.IX Item "collectd options"
+Specify options that are passed on to collectd. If it is not already included,
+\&\fB\-f\fR will be added to these options. See \fIcollectd\fR\|(1).
+.SH "SIGNALS"
+.IX Header "SIGNALS"
+\&\fBcollectdmon\fR accepts the following signals:
+.IP "\fB\s-1SIGINT\s0\fR, \fB\s-1SIGTERM\s0\fR" 4
+.IX Item "SIGINT, SIGTERM"
+These signals cause \fBcollectdmon\fR to terminate \fBcollectd\fR, wait for its
+termination and then shut down.
+.IP "\fB\s-1SIGHUP\s0\fR" 4
+.IX Item "SIGHUP"
+This signal causes \fBcollectdmon\fR to terminate \fBcollectd\fR, wait for its
+termination and then restart it.

+=head1 NAME
+
+collectdmon - Monitoring daemon for collectd
+
+=head1 SYNOPSIS
+
+collectdmon I<[options]> [-- I<collectd options>]
+
+=head1 DESCRIPTION
+
+collectdmon is a small "wrapper" daemon which starts and monitors the collectd
+daemon. If collectd terminates it will automatically be restarted, unless
+collectdmon was told to shut it down.
+
+=head1 OPTIONS
+
+collectdmon supports the following options:
+
+=over 4
+
+=item B<-c> I<E<lt>pathE<gt>>
+
+Specify the pathname of the collectd binary. You may either specify an
+absolute path or simply the name of the binary in which case the B<PATH>
+variable will be searched for it. The default is "B<collectd>".
+
+=item B<-P> I<E<lt>pid-fileE<gt>>
+
+Specify the pid file. The default is "I</var/run/collectdmon.pid>".
+
+=item B<-h>
+
+Output usage information and exit.
+
+=item I<collectd options>
+
+Specify options that are passed on to collectd. If it is not already included,
+B<-f> will be added to these options. See L<collectd(1)>.
+
+=back
+
+=head1 SIGNALS
+
+B<collectdmon> accepts the following signals:
+
+=over 4
+
+=item B<SIGINT>, B<SIGTERM>
+
+These signals cause B<collectdmon> to terminate B<collectd>, wait for its
+termination and then shut down.
+
+=item B<SIGHUP>
+
+This signal causes B<collectdmon> to terminate B<collectd>, wait for its
+termination and then restart it.

+ * NOTES
+ *  `cf_unregister' will be called for `type' to make sure only one record

+ *
+ * DESCRIPTION
+ *  Takes a list of type instances and values and dispatches that in a batch,

+ *  NaN are dispatched as NaN and will not influence the total.
+ *
+ *  The variadic arguments is a list of type_instance / type pairs, that are
+ *  interpreted as type "char const *" and type, encoded by their corresponding
+ *  "store_type":
+ *
+ *     - "gauge_t"    when "DS_TYPE_GAUGE"
+ *     - "absolute_t" when "DS_TYPE_ABSOLUTE"
+ *     - "derive_t"   when "DS_TYPE_DERIVE"

+ *  The number of values it failed to dispatch (zero on success).

+ *   Adds a match, in form of a `cu_match_t' object, to the object.
+ *   After data has been read from the logfile (using utils_tail) the callback
+ *   function `submit_match' is called with the match object and the user
+ *   supplied data.
+ *   Please note that his function is called regardless whether this match
+ *   matched any lines recently or not.
+ *   When `tail_match_destroy' is called the `user_data' pointer is freed using
+ *   the `free_user_data' callback - if it is not NULL.
+ *   When using this interface the `tail_match' module doesn't dispatch any values
+ *   itself - all that has to happen in either the match-callbacks or the
+ *   submit_match callback.
+ *
+ * RETURN VALUE
+ *   Zero upon success, non-zero otherwise.

+ * NAME
+ *  tail_match_add_match_simple
+ *
+ * DESCRIPTION
+ *  A simplified version of `tail_match_add_match'. The regular expressen `regex'
+ *  must match a number, which is then dispatched according to `ds_type'. See
+ *  the `match_create_simple' function in utils_match.h for a description how
+ *  this flag effects calculation of a new value.
+ *  The values gathered are dispatched by the tail_match module in this case. The
+ *  passed `plugin', `plugin_instance', `type', and `type_instance' are
+ *  directly used when submitting these values.
+ *  With excluderegex it is possible to exlude lines from the match.

+                   GNU GENERAL PUBLIC LICENSE
+                      Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                    END OF TERMS AND CONDITIONS
+\f
+           How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    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.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.

+
+
+/**
+ * There are several data streams provided by Madwifi plugin, some are 
+ * connected to network interface, some are connected to each node
+ * associated to that interface. Nodes represents other sides in
+ * wireless communication, for example on network interface in AP mode,
+ * there is one node for each associated station. Node data streams
+ * contain MAC address of the node as the last part  of the type_instance
+ * field.
+ *
+ * Inteface data streams:
+ *     ath_nodes       The number of associated nodes
+ *     ath_stat        Device statistic counters
+ *
+ * Node data streams:
+ *     node_octets     RX and TX data count (octets/bytes)
+ *     node_rssi       Received RSSI of the node
+ *     node_tx_rate    Reported TX rate to that node
+ *     node_stat       Node statistic counters
+ *
+ * Both statistic counters have type instances for each counter returned
+ * by Madwifi. See madwifi.h for content of ieee80211_nodestats, 
+ * ieee80211_stats and ath_stats structures. Type instances use the same
+ * name as fields in these structures (like ns_rx_dup). Some fields are
+ * not reported, because they are not counters (like ns_tx_deauth_code
+ * or ast_tx_rssi). Fields ns_rx_bytes and ns_tx_bytes are reported as
+ * node_octets data stream instead of type instance of node_stat.
+ * Statistics are not logged when they are zero.
+ * 
+ * There are two sets of these counters - the first 'WatchList' is a
+ * set of counters that are individually logged. The second 'MiscList'
+ * is a set of counters that are summed together and the sum is logged.
+ * By default, the most important statistics are in the WatchList and 
+ * many error statistics are in MiscList. There are also many statistics
+ * that are not in any of these sets, so they are not monitored by default.
+ * It is possible to alter these lists using configuration options:
+ *
+ *     WatchAdd X      Adds X to WachList
+ *     WatchRemove X   Removes X from WachList
+ *     WatchSet All    Adds all statistics to WatchList
+ *     WatchSet None   Removes all statistics from WachList
+ *
+ * There are also Misc* variants fo these options, they modifies MiscList
+ * instead of WatchList.
+ *
+ * Example:
+ *
+ *     WatchSet None
+ *     WatchAdd node_octets
+ *     WatchAdd node_rssi
+ *     WatchAdd is_rx_acl
+ *     WatchAdd is_scan_active
+ *
+ * That causes that just the four mentioned data streams are logged.
+ *
+ *
+ * By default, madwifi plugin enumerates network interfaces using /sys
+ * filesystem. Configuration option `Source' can change this to use
+ * /proc filesystem (which is useful for example when running on Linux
+ * 2.4). But without /sys filesystem, Madwifi plugin cannot check whether
+ * given interface is madwifi interface and there are private ioctls used,
+ * which may do something completely different on non-madwifi devices.
+ * Therefore, the /proc filesystem should always be used together with option
+ * `Interface', to limit found interfaces to madwifi interfaces only.

+ *
+ * This has only tested with the model 1001 RDU, with

+The types.db file contains one line for each data-set specification. Each line
+consists of two fields delimited by spaces and/or horizontal tabs. The first

+The format of the data-source specification has been inspired by RRDtool's

+range of valid values for
+data stored for this data-source. If \fBU\fR is specified for either the min or

+=head1 DESCRIPTION
+
+The types.db file contains one line for each data-set specification. Each line
+consists of two fields delimited by spaces and/or horizontal tabs. The first
+field defines the name of the data-set, while the second field defines a list
+of data-source specifications, delimited by spaces and, optionally, a comma
+(",") right after each list-entry.
+
+The format of the data-source specification has been inspired by RRDtool's
+data-source specification. Each data-source is defined by a quadruple made up
+of the data-source name, type, minimal and maximal values, delimited by colons
+(":"): I<ds-name>:I<ds-type>:I<min>:I<max>. I<ds-type> may be either
+B<ABSOLUTE>, B<COUNTER>, B<DERIVE>, or B<GAUGE>. I<min> and I<max> define the
+range of valid values for
+data stored for this data-source. If B<U> is specified for either the min or
+max value, it will be set to unknown, meaning that no range checks will
+happen. See L<rrdcreate(1)> for more details.
+
+=head1 FILES
+
+The location of the types.db file is defined by the B<TypesDB> configuration
+option (see L<collectd.conf(5)>). It defaults to collectd's shared data
+directory, i.E<nbsp>e. F<I<prefix>/share/collectd/>.
+
+=head1 CUSTOM TYPES
+
+If you want to specify custom types, you should do so by specifying a custom
+file in addition to the default one (see L<FILES>) above. You can do that by
+having multiple B<TypesDB> statements in your configuration file or by
+specifying more than one file in one line.

+ *  COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or
+ *  code or tables extracted from it, as desired without restriction.
+ *
+ *  First, the polynomial itself and its table of feedback terms.  The
+ *  polynomial is
+ *  X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ *  Note that we take it "backwards" and put the highest-order term in
+ *  the lowest-order bit.  The X^32 term is "implied"; the LSB is the
+ *  X^31 term, etc.  The X^0 term (usually shown as "+1") results in
+ *  the MSB being 1
+ *
+ *  Note that the usual hardware shift register implementation, which
+ *  is what we're using (we're merely optimizing it by doing eight-bit
+ *  chunks at a time) shifts bits into the lowest-order term.  In our
+ *  implementation, that means shifting towards the right.  Why do we
+ *  do it this way?  Because the calculated CRC must be transmitted in
+ *  order from highest-order term to lowest-order term.  UARTs transmit
+ *  characters in order from LSB to MSB.  By storing the CRC this way
+ *  we hand it to the UART in the order low-byte to high-byte; the UART
+ *  sends each low-bit to hight-bit; and the result is transmission bit
+ *  by bit from highest- to lowest-order term without requiring any bit
+ *  shuffling on our part.  Reception works similarly
+ *
+ *  The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ *      The table can be generated at runtime if desired; code to do so
+ *      is shown later.  It might not be obvious, but the feedback
+ *      terms simply represent the results of eight shift/xor opera
+ *      tions for all combinations of data and CRC register values
+ *
+ *      The values must be right-shifted by eight bits by the "updcrc
+ *      logic; the shift must be unsigned (bring in zeroes).  On some
+ *      hardware you could probably optimize the shift in assembler by
+ *      using byte-swap instructions

+ * 
+ * Define plugin's global pointer variable of type ignorelist_t:
+ *   ignorelist_t *myconfig_ignore;
+ * If you know the state of the global ignore (IgnoreSelected),
+ * allocate the variable with:
+ *   myconfig_ignore = ignorelist_create (YourKnownIgnore);
+ * If you do not know the state of the global ignore,
+ * initialize the global variable and set the ignore flag later:
+ *   myconfig_ignore = ignorelist_init ();
+ * Append single entries in your cf_register'ed callback function:
+ *   ignorelist_add (myconfig_ignore, newentry);
+ * When you hit the IgnoreSelected config option,
+ * offer it to the list:
+ *   ignorelist_ignore (myconfig_ignore, instantly_got_value_of_ignore);
+ * That is all for the ignorelist initialization.
+ * Later during read and write (plugin's registered functions) get
+ * the information whether this entry would be collected or not:

+/*
+  DESCRIPTION
+       The cu_mount_checkoption() function is a replacement of
+       char *hasmntopt(const struct mntent *mnt, const char *opt).
+       In fact hasmntopt() just looks for the first occurrence of the
+       characters at opt in mnt->mnt_opts. cu_mount_checkoption()
+       checks for the *option* keyword in line, starting at the
+       first character of line or after a ','.
+
+       If full is not 0 then also the end of keyword has to match
+       either the end of line or a ',' after keyword.
+
+  RETURN VALUE
+       The cu_mount_checkoption() function returns a pointer into
+       string line if a match of keyword is found. If no match is
+       found cu_mount_checkoption() returns NULL.
+
+  NOTES
+       Do *not* try to free() the pointer which is returned! It is
+       just part of the string line.
+
+       full should be set to 0 when matching options like: rw, quota,
+       noatime. Set full to 1 when matching options like: loop=,
+       gid=, commit=.
+
+  EXAMPLES
+       If line is "rw,usrquota,grpquota", keyword is "quota", NULL
+       will be returned (independend of full).
+
+       If line is "rw,usrquota,grpquota", keyword is "usrquota",
+       a pointer to "usrquota,grpquota" is returned (independend
+       of full).
+
+       If line is "rw,loop=/dev/loop1,quota", keyword is "loop="
+       and full is 0, then a pointer to "loop=/dev/loop1,quota"
+       is returned. If full is not 0 then NULL is returned. But
+       maybe you might want to try cu_mount_getoptionvalue()...

+  DESCRIPTION

+       If the cu_mount_getoptionvalue() function can find the option
+       keyword in line, then memory is allocated for the value of
+       that option and a pointer to that value is returned.
+
+       If the option keyword is not found, cu_mount_getoptionvalue()
+       returns NULL;
+
+  NOTES
+       Internally it calls cu_mount_checkoption(), then it
+       allocates memory for VALUE and returns a pointer to that
+       string. So *do not forget* to free() the memory returned
+       after use!!!
