12 multicast traffic from Ganglia's gmond daemon.
13 * java plugin: The new java plugin exports the collectd API to Java,
14 making it possible to write extensions to collectd in Java.
15 * memcachec plugin: The new memcachec plugin queries data from a
16 memcached daemon and parses it similar to the cURL plugin. Thanks to
17 Doug MacEachern for the initial code.

30 plugin must no longer be a multiple of the global interval.
31 * table plugin: The new Table plugin provides parsing for table-like
32 structured files, such as many files beneath /proc.
33 * ted plugin: The new TED plugin reads power consumption measurements
34 from “The Energy Detective” (TED). Thanks to Eric Reed for this

45 * filter subsystem: Allow `Chains' without default targets.
46 * liboping: A patch to comply with strict aliasing rules has been
48 * timediff match: Fix a typo: The match was registered with a wrong
49 name which prevented this match to be used as documented. Thanks to
50 Bruno Prémont for finding this problem.
51 * bind plugin: Fix collection of the cached RR sets. The number of RR
52 sets currently in the cache was collected as a counter value, which
53 is nonsense. Thanks to Bruno Prémont for implementing this.
54 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
55 primarily BSDs, don't take it well and crash.
56 * oracle plugin: Portability to 64 bit systems has been improved.
57 * postgresql plugin: The default configuration has been improved.
58 * rrdtool plugin: Fix a possible race condition: If the network plugin

69 faults. Thanks to Peter Holik for his patch.
71 2009-02-16, Version 4.6.0
72 * collectd: Added the `filter chain' infrastructure, which allows the
73 user to use `matches' and `targets' to control value processing.
74 * collectd: The new `-T' command line argument allows more in-depth
75 testing of a configuration. Thanks to Doug MacEachern for the patch.
76 * collectd-nagios: The Nagios integration command has been updated to
77 use libcollectdclient. The `percentage' aggregation function has
78 been added. Thanks to Fabian Linzberger for the patch.

90 statistics, allowing very detailed name server statistics. Thanks to
91 Bruno Prémont for this plugin.
92 * cpu plugin: Report `interrupt' separately when using
93 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
94 example for native OpenBSD support, has been added. Thanks to Simon
96 * csv plugin: Make it possible to write values to STDOUT instead of
97 files. This is meant for testing purposes mostly. The output written
98 to STDOUT is compatible with the exec plugin. Thanks to Doug
99 MacEachern for the patch.
100 * curl plugin: This new plugin can be used to read web pages and parse
101 them using the same mechanism that's used in the tail plugin.
102 * dbi plugin: This new plugin allows you to connect to a variety of
103 relational databases and use SQL to gather custom statistics from
104 it. It is similar to the already existing PostgreSQL plugin but uses
105 libdbi to communicate with the database(s).
106 * interface plugin: Use the ignorelist framework when selecting /
107 ignoring interfaces. This allows one to use regular expressions to
108 select interfaces, too.
109 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
110 Thanks to Bruno Prémont for this patch.
111 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
113 * mysql plugin: Allow connecting to a database via the UNIX domain
114 socket, too. Thanks to Mirko Buffoni for the patch.

122 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
124 * perl plugin: Export the newly added plugin_write() to Perl plugins.
125 * perl plugin: Added support for `notification meta data'.
126 * perl plugin: Added support for the `filter chain' infrastructure by
127 allowing plugins to register `matches' and `targets'.
128 * postgresql plugin: The preferred configuration syntax has been
129 updated to be in line with the syntax used by the new dbi and oracle
130 plugins. The compatibility code for the old syntax is present.
131 Support for the new `Result' blocks and the interval parameter has
133 * processes plugin: Stacksize and virtual memory usage statistics have
134 been added. Portability fixes.
135 * rrdcached plugin: This new plugin uses the (still in development)
136 RRD accelerator daemon, rrdcached. This daemon works very similar to
137 the original rrdtool plugin of collectd, but adds some more nice
139 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
142 2009-02-22, Version 4.5.3
143 * build system: The check for libupsclient even when `pkg-config' is
145 * collectd: Fix error handling in the global cache.
146 * Collectd::Unixsock: Error handling has been improved.
147 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

152 code. Thanks to "thated" for reporting this.
154 2009-01-02, Version 4.5.2
155 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
156 file may be in both locations, especially when the database was
157 installed in a non-standard path. Thanks to Dusty Doris for
159 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
160 Solaris, in the configure script automatically.
161 * build system, tcpconns plugin: Check for `kvm_nlist' and
162 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
163 library with similar functions to the BSD variant, but doesn't
164 provide these necessary functions.
165 * collectd.conf(5): Various fixes and clarifications.
166 * collectd: Remove a GNUism (unnamed unions), thus improving
168 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
169 This solves portability problems, especially for Solaris.
170 * dns plugin: Fix a portability problem with NetBSD.
171 * filecount plugin: Fix an off-by-one error. This error may cause a
173 * network plugin: Fix the handling of `type' in the network protocol.
174 Due to a programming mistake, only 4 or 8 bytes would be copied to a
175 much larger buffer. This caused the `type' to be transferred much
176 more often than necessary. In some cases, e. g. the `cpu' and
177 `cpufreq' plugins being used at the same time, data may be corrupted
178 in those files. Thanks to Bruno Prémont for debugging and reporting
180 * processes plugin: Fix a possible segmentation fault when specifying
181 invalid configuration options.
182 * unixsock plugin: Make sure the initialization function is run only
183 once. This resolves a file descriptor leak under systems which run
184 the initialization more than once, such as Solaris.
186 2008-10-16, Version 4.5.1
187 * build system: Change `--enable-<plugin>' to abort with an error if
188 dependencies are not met. Thanks to Bruno Prémont for the patch.
189 Also, the poisoning of various string functions has been restricted
191 * collectd: Fix a memory leak in the global value cache. With every
192 *missing* value a couple of bytes would be leaked. Another memory
193 leak in the configuration handling code has been fixed. Thanks to
194 Niraj Tolia for reporting these issues.
195 * collectd: Fix an off-by-one error in the ignorelist functionality.
196 When using regular expressions, the last character would be missing,
197 possibly matching differently from what one would expect.
198 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
200 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
201 Linzberger for reporting the bug.
202 * iptables plugin: Fix an off-by-one error. If a string was just one
203 character too long, it was truncated instead of reporting an error.
204 * network plugin: Fix a memory leak in the configuration handling
205 code. Thanks to Niraj Tolia for reporting this issue.
206 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
207 * postgresql plugin: Don't reopen connection during reinitialization.
208 This fixes a bug under Solaris and potentially other platforms.
209 Missing calls to `PQclear' have been added, too. This fixes memory
210 leaks. Thanks to ``Admin'' for reporting these bugs.
211 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
213 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
214 problems with some `libc's. Thanks to Matthias Lay for reporting the
217 2008-09-04, Version 4.5.0
218 * collectd: Added the ability to flush certain identifiers.
219 * collectd: The concept of `notification meta data' has been
221 * filecount plugin: The new filecount plugin counts the number of
222 files in a directory and its subdirectories.
223 * ipmi plugin: Sensor names have been changed to ensure unique names.
224 Notifications upon added and removed sensors can now be generated.
225 * notify_desktop plugin: This new plugin sends notifications to the
226 X desktop using the structure defined in the `Desktop Notification
228 * notify_email plugin: This new plugin sends out notifications via
229 email, using the `esmtp' library.
230 * onewire plugin: The new experimental(!) onewire plugin reads values,
231 such as temperatures, from sensors connected to the computer via the
233 * perl plugin: Improved synchronized access to internal data structures
234 and fixed a possible dead-lock.
235 * perl plugin: Added the ability to flush certain identifiers and marked
236 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
238 * perl plugin: Added the ability to configure Perl plugins.
239 * postgresql plugin: The new postgresql plugin collects statistics
240 about or from a PostgreSQL database.
241 * processes plugin: The `ProcessMatch' option has been added.
242 * rrdtool plugin: Implement throttling of the `update queue' to lessen
244 * tcpconns plugin: This plugin has been ported to OpenBSD.

246 using Linux ACPI thermal zone data.
248 2009-01-02, Version 4.4.5
249 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
250 file may be in both locations, especially when the database was
251 installed in a non-standard path. Thanks to Dusty Doris for
253 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
254 Solaris, in the configure script automatically.
255 * collectd.conf(5): Various fixes and clarifications.
256 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
257 portability problems, especially for Solaris.
258 * dns plugin: Fix a portability problem with NetBSD.
259 * network plugin: Fix the handling of `type' in the network protocol.
260 Due to a programming mistake, only 4 or 8 bytes would be copied to a
261 much larger buffer. This caused the `type' to be transferred much
262 more often than necessary. In some cases, e. g. the `cpu' and
263 `cpufreq' plugins being used at the same time, data may be corrupted
264 in those files. Thanks to Bruno Prémont for debugging and reporting
266 * unixsock plugin: Make sure the initialization function is run only
267 once. This resolves a file descriptor leak under systems which run
268 the initialization more than once, such as Solaris.
270 2008-10-16, Version 4.4.4
271 * build system: Change `--enable-<plugin>' to abort with an error if
272 dependencies are not met. Thanks to Bruno Prémont for the patch.
273 Also, the poisoning of various string functions has been restricted

306 * dns plugin: Fix compilation errors with BIND versions 19991001
308 * network plugin: Bugfix in the init routine: The init function
309 cleared a buffer regardless of its contents. This could lead to lost
310 values under Solaris.
311 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
312 * vserver plugin: Remove usage of the thread-unsafe `readdir'
314 * wireless plugin: Work around incorrect noise and power values
315 returned by some broken drivers.
317 2008-06-03, Version 4.4.1
318 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
319 to kyrone for reporting this.
320 * collectd: Fixed min/max output in notifications generated by
322 * collectd-nagios: Fix the protocol used to communicate with the
324 * perl plugin: Fail noisily, but don't shutdown the daemon, if
325 initialization has errors. An issue with Perl 5.10 has been fixed.
326 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
327 René Rebe and Siegmund Gorr for reporting this.
329 2008-05-06, Version 4.4.0
330 * collectd: Internal code cleanups.
331 * collectd: Added support for a `Flush' command in the unixsock and
332 exec plugins. This command can be used to force a plugin (or all) to
333 flush its values to disk.
334 * collectd: Thresholds can now be configured to apply to one data
335 source only, making it possible to configure different thresholds
336 for each data source.

349 plugin has been added to the distribution, because it is not
350 provided by all distributions and removed from at least one.
351 * powerdns plugin: The new powerdns plugin reads statistics from an
352 authoritative or a recursing PowerDNS name server.
353 * rrdtool plugin: The size of the files generated with the default
354 configuration has been decreased.
355 * tail plugin: The new tail plugin can be used to gather statistics by
356 continuously reading from log files.

409 + Use `memcpy' when constructing/parsing a package to avoid
410 alignment problems on weird architectures, such as Sparc.
411 + Translate doubles to/from the x86 byte representation to ensure
412 cross-platform compatibility.
413 * ping plugin: Correct the handling of the `TTL' setting.
414 * swap plugin: Reapply a patch for Solaris.
415 * tcpconns plugin: Portability improvements.

419 are status messages that may be associated with a data instance.
420 * collectd: Threshold checking has been added to the daemon. This
421 means that you can configure threshold values for each data
422 instance. If this threshold is exceeded a notification will be
424 * collectd: The new `FQDNLookup' option tells the daemon to use the
425 full qualified domain name as the hostname, not just the host part
426 es returned by `gethostname(2)'.
427 * collectd: Support for more than one `TypesDB' file has been added.
428 This is useful when one such file is included in a package but one
429 wants to add custom type definitions.
430 * collectd: The `Include' config option has been expanded to handle
431 entire directories and shell wildcards.
432 * collectdmon: The new `collectdmon' binary detects when collectd
433 terminates and automatically restarts it again.
434 * csv plugin: The CSV plugin is now able to store counter values as a
435 rate, using the `StoreRates' configuration option.
436 * exec plugin: Handling of notifications has been added and the
437 ability to pass arguments to the executed programs has been added.
438 * hddtemp plugin: The new `TranslateDevicename' option lets you
439 disable the translation from device names to major-minor-numbers.
440 * logfile plugin: Handling of notifications has been added.
441 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
442 domain name lookups in this plugin.
443 * perl plugin: Many internal changes added support for handling multiple
444 threads making the plugin reasonably usable inside collectd. The API has
445 been extended to support notifications and export global variables to
446 Perl plugins; callbacks now have to be identified by name rather than a
447 pointer to a subroutine. The plugin is no longer experimental.
448 * uuid plugin: The new UUID plugin sets the hostname to an unique
449 identifier for this host. This is meant for setups where each client
450 may migrate to another physical host, possibly going through one or
451 more name changes in the process. Thanks to Richard Jones from
452 Red Hat's Emerging Technology group for this plugin.
453 * libvirt: The new libvirt plugin uses the `libvirt' library to query
454 CPU, disk and network statistics about guest systems on the same
455 physical server. Thanks to Richard Jones from Red Hat's Emerging
456 Technology group for this plugin.
458 2008-04-22, Version 4.2.7
459 * build system: Improved detection of several libraries, especially if

480 * apache plugin: Improved initialization and error messages.
481 * exec plugin: Set supplementary group IDs.
483 + Create separate threads for reading from the socket and parsing
484 and dispatching incoming packets. Versions prior to this may have
485 problems in high-load situations, where the socket receive buffers
486 overflows, resulting in gaps in the data.
487 + Use `memcpy' when constructing/parsing a package to avoid
488 alignment problems on weird architectures, such as Sparc.
489 + Translate doubles to/from the x86 byte representation to ensure
490 cross-platform compatibility.
491 * ping plugin: Correct the handling of the `TTL' setting.
492 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
493 * swap plugin: Reapply a patch for Solaris.

498 the permission on the socket as documented in the manpage. Thanks to
499 Evgeny Chukreev for fixing this issue.
500 * collectd: The documentation has been improved.
502 2007-12-28, Version 4.2.3
503 * sensors plugin: Updated the plugin to build and work with version 3
504 of the libsensors library.
506 2007-12-15, Version 4.2.2
507 * nginx plugin: Incorrect comparison of strings lead to a segfault
508 when using the plugin. Thanks to Saulius Grigaliunas for fixing
510 * logfile plugin: The config option `Timestamp' was handled
511 incorrectly and basically always active. Thanks to Luke Heberling
514 2007-11-08, Version 4.2.1
515 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
517 * snmp plugin: Fix a memory leak.
519 2007-10-27, Version 4.2.0
520 * collectd: The new config option `Include' lets you include other
521 configfiles and thus split up your config into smaller parts. This
522 may be especially interesting for the snmp plugin to keep the data
523 definitions separate from the host definitions.
524 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
525 (number of connections, octets and packets for each service and
526 destination). Thanks to Sebastian Harl for this plugin.
527 * memcached plugin: The new `memcached' plugin connects to a memcached
528 daemon process and collects statistics of this distributed caching
529 system. Thanks to Antony Dovgal for contributing this plugin.
530 * nginx plugin: The new `nginx' plugin reads the status page of an
531 nginx daemon and saves the handled connections and requests.
532 * perl plugin: Many changes, including the added `EnableDebugger'
533 config option which lets you debug your Perl plugins more easily.
534 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
535 be more thread-safe otherwise by locking calls to the library.
536 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
537 correct the values returned by SNMP-agents. If a <data> block is
538 defined as `table' the instance is now optional. The sequence number
539 is used as the type-instance in this case. The new `InstancePrefix'
540 option allows to add arbitrary prefixes to the type-instance.
541 * tcpconns plugin: The new `tcpconns' plugin collects the number of
542 certain TCP connections and what state they're in. This can be used
543 to see how many connections your FTP server has to handle or how
544 many outgoing connections your mailserver has open.
546 2008-01-11, Version 4.1.6
547 * unixsock plugin: A bug in the unixsock plugin caused it not to set
548 the permission on the socket as documented in the manpage. Thanks to
549 Evgeny Chukreev for fixing this issue.
550 * collectd: The documentation has been improved.
552 2007-12-27, Version 4.1.5
553 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

556 of the libsensors library.
558 2007-11-08, Version 4.1.4
559 * Build system: Improve detection of the rrd library, especially if
560 it's in a non-standard location.
561 * Build system: A bug when parsing the argument for
562 `--with-libnetsnmp' has been fixed.
563 * collectd: Implement `strerror_r' if the libc doesn't provide it.
564 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
565 a deadlock or delay when shutting down the daemon.
566 * snmp plugin: Fix a memory leak.
568 2007-10-24, Version 4.1.3
569 * collectd: A build issue under Solaris has been resolved by renaming
571 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
572 be more thread-safe otherwise by locking calls to the library.
574 2007-09-28, Version 4.1.2
575 * apcups plugin: Fix reporting of the `load percent' data.
576 * wireless plugin: Correct the handling of cards returning signal and
577 noise quality as percentage.
578 * perl plugin: Fix a possible buffer overflow in get_module_name().
579 * build system: Further improve the detection of libraries.
580 * netlink plugin: Build issues under some older versions of the Linux
581 includes (i. e. Debian Sarge) have been fixed.
582 * snmp plugin: Fix a potential segfault when a host times out. Add
583 support for the `timeticks' type.
585 2007-09-12, Version 4.1.1
586 * Build system: The detection of `libnetlink' has been improved.
587 * collectd: The documentation has been fixed in numerous places.
588 * exec plugin: Setting the group under which to run a program has been
590 * collectd: The `sstrerror' function was improved to work correctly
591 with the broken GNU version of `strerror_r'.
592 * collectd: Write an error message to STDERR when loading of a plugin
594 * apcups plugin: Fix the `types' used to submit the values: They still
595 has an `apcups_' prefix which doesn't work anymore.
596 * rrdtool plugin: Create new RRD-files with the `begin' time set to
597 whatever the client thinks is `now'..
599 2007-09-01, Version 4.1.0
600 * Build system: The build system has been changed to automatically
601 disable all plugins, which are missing dependencies. The dependency
602 checking has been removed from the plugins themselves to remove
604 * Flexible interval: The interval of collected data is now sent along
605 with the data itself over the network, so that the interval-settings
606 of server and clients no longer needs to match.
607 * netlink plugin: The new `netlink' plugin connects to the Linux
608 kernel using a netlink socket and uses it to query information about
609 interfaces, qdiscs and classes.
610 * rrdtool plugin: The cache is now dumped to disk in an extra thread
611 to not block data collection.
612 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
613 network devices, such as switches, routers, thermometers, rack
614 monitoring servers, etc. The collectd-snmp(5) manpage documents this
616 * unixsock plugin: Added the `LISTVAL' command.
617 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
618 of music played with xmms.
620 2007-09-28, Version 4.0.9
621 * apcups plugin: Fix reporting of the `load percent' data.
622 * wireless plugin: Correct the handling of cards returning signal and
623 noise quality as percentage.
624 * perl plugin: Fix a possible buffer overflow in get_module_name().
626 2007-09-12, Version 4.0.8
627 * collectd: The `sstrerror' function was improved to work correctly
628 with the broken GNU version of `strerror_r'.
629 * collectd: Write an error message to STDERR when loading of a plugin
631 * apcups plugin: Fix the `types' used to submit the values: They still
632 has an `apcups_' prefix which doesn't work anymore.
633 * rrdtool plugin: Create new RRD-files with the `begin' time set to
634 whatever the client thinks is `now'..
636 2007-08-26, Version 4.0.7
637 * documentation: Some typos have been fixed and some information has
639 * build system: Many fixes for detecting libraries in unusual places,
640 such as on RedHat systems. The affected libraries are `libcurl',
641 `libmysql', and `libupsclient'.
642 * network plugin: Allow the `Port' option to be specified as a number
643 (i. e. without quotes).
644 * nut plugin: A fix allows linking the nut plugin against
645 libupsclient, version >= 2.2.0.
646 * processes plugin: Fix a potential segmentation fault.
648 2007-07-30, Version 4.0.6
649 * sensors plugin: Fix the ignorelist functionality: Only the `type
650 instance' was used to match against the list, but the documentation
651 told otherwise. This release fixes the code, so it complies with the
653 * syslog plugin: Call `openlog' right when the plugin is loaded, so
654 configuration messages will end up in the logging facility.
655 * conrtib/fedora: The contributed specfile for Fedora has been
658 2007-07-05, Version 4.0.5
659 * Portability: More fixes for OpenBSD have been included.
661 2007-06-24, Version 4.0.4
662 * cpu plugin: Fixed the Solaris code.

667 * oconfig: Don't require `-lfl' anymore.
669 2007-06-19, Version 4.0.3
670 * cpu plugin: Fix the Darwin / Mac OS X code.
671 * ping plugin: Use the return value of `getpid', not its address.
672 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
673 initialized correctly.
674 * configure: Added `--with-nan-emulation' to aid cross compilation.
676 2007-06-12, Version 4.0.2

678 they're given in numerically form.
680 2007-06-07, Version 4.0.1
681 * iptables plugin: A bug in the configuration routine has been fixed.
682 Setting a comment in the configfile will no longer cause a
685 2007-06-03, Version 4.0.0
686 * collectd: The plugin-infrastructure has been changed to allow for
687 more types of plugins, namely `write' and `log' plugins.
688 * collectd: The read-function has been changed to read many plugins in
689 parallel, using threads. Thus, plugins generally need to use
690 thread-safe functions from now on.
691 * collectd: The '-t' command line options allows to perform syntax tests
692 of the configuration file and exit immediately.
693 * csv plugin: The new `csv' plugin handles output to `comma separated
695 * rrdtool plugin: The new `rrdtool' plugin handles output to
696 RRD-files. Data can be cached to combine multiple updates into one
697 write to increase IO-performance.
698 * network plugin: The new `network' plugin handles IO via the network.
699 It implements a different, much more extensible protocol which can
700 combine many values in one packet, decreasing the number of UDP-
701 packets being sent. It can read from and send to the network and
702 with the appropriate configuration even forward packets to other
704 * unixsock plugin: The new `unixsock' plugin provides an interface to
705 communicate with the daemon while it is running. Right now the
706 commands `GETVAL' and `PUTVAL' are implemented, but more are to
708 * perl plugin: The new `perl' plugin allows you to write extensions
709 for collectd in the scripting-language Perl.
710 * logfile plugin: The new `logfile' plugin writes logmessages to files
712 * syslog plugin: The new `syslog' plugin sends logmessages to the
713 system's syslog daemon.
714 * entropy plugin: The new `entropy' plugin collects the amount of
715 entropy currently being available to the system.
716 * exec plugin: The new `exec' plugin forks child processes and reads
717 back values provided by the forked processes.
718 * iptables plugin: The new `iptables' plugin reads counters from
719 iptables rules. Thanks to Sjoerd van der Berg for contributing this
721 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
722 to Peter Holik for contributing this plugin.
723 * nut plugin: The new `nut' plugin connects the upsd of the `network
724 ups tools' and reads information about the connected UPS.
725 * apache plugin: Support for lighttpd's `BusyServers' (aka.
726 connections) field was added by Florent Monbillard.
727 * collectd-nagios: The new `collectd-nagios' binary queries values
728 from collectd, parses them and exits according to Nagios-standards.
729 * manpages: The manpages have been improved a lot.
731 2007-09-28, Version 3.11.7
732 * wireless plugin: Correct the handling of cards returning signal and
733 noise quality as percentage.
735 2007-08-31, Version 3.11.6

739 * configure: Added `AC_SYS_LARGEFILE' for LFS.
740 * ntpd plugin: Fix a potential buffer overflow.
741 * processes plugin: Fix a bug when run under Linux 2.4. All processes
742 were accounted as `zombies'.
744 2007-04-10, Version 3.11.4
745 * dns plugin: Change the order of includes to make the plugin compile
748 2007-03-30, Version 3.11.3
749 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
750 of the unused `COLLECT_KSTAT'.
752 2007-02-11, Version 3.11.2
753 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
754 NULL-pointer may have been passed to `printf' which causes a
755 segfault with some libcs.
757 2007-02-10, Version 3.11.1
758 * df plugin: Some wrong defines have been fixed so the plugin works
760 * dns plugin: The usage of a struct has been fixed to work with
762 * processes plugin: Some missing defines have been added so the plugin
763 compiles cleanly under FreeBSD and presumably other UNIXes.
765 2006-12-22, Version 3.11.0
766 * collectd: The new command line option `-P' makes it easier for
767 distributors to change the location of PID-files.
768 * collectd: The daemon shuts down faster now which makes it easier to
769 write init.d-scripts for it.
770 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
771 caused problems every now and then.
772 * df plugin: New config options allow to ignore certain mountpoints,
773 filesystem types or devices.
774 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
775 and interprets it. It collects traffic as well as qtype, opcode and
777 * email plugin: Sebastian Harl has contributed this plugin which
778 counts received mails in categories (e. g. ham, spam, virus), spam
779 score (as given by SpamAssassin) and check types.
780 * mbmon plugin: Flavio Stanchina has contributed this plugin which
781 uses `mbmon' to gather information from sensors on the motherboard.
782 * processes plugin: Collect detailed statistics for configured
783 processes, that's process and thread count, CPU usage, resident
784 segment size and pagefaults.
785 * multimeter plugin: Peter Holik contributed a new plugin which
787 * sensors plugin: Lubos Stanek has put much effort into improving this
788 plugin, including `extended naming', collection of voltage values
789 and the possibility to ignore certain values.
791 2006-12-21, Version 3.10.4
792 * Max Kellermann has identified a bug in the server routine: When
793 opening a socket fails the daemon will (re)try opening the socket in
794 an endless loop, ultimately leading to a `EMFILE' error.
796 2006-11-04, Version 3.10.3
797 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
798 ntpd's reply was sent in more than one packet, the buffer size was
799 calculated incorrectly, resulting in the reading of uninitialized or
802 2006-11-01, Version 3.10.2
803 * The sample config file has been improved.
804 * Errors in the manpages have been corrected.
805 * The ping-plugin now adds hosts during initialization, not during
806 startup. This speeds up startup when no network connectivity is
807 available. Also, the hosts are being added later when the network is
809 * Improved BSD-support for the df-plugin.
810 * Fixed syntax errors in the swap-plugin for Mac OS X.
811 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
813 * Don't disable the mysql-plugin if connecting to the database fails
814 during initialization. Instead, try again in increasing intervals.
816 2006-07-19, Version 3.10.1
817 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
818 the apcups cannot be reached, unconnected sockets will pile up and
819 eventually lead to `Too many open files' errors.
821 2006-07-09, Version 3.10.0
822 * The `disk' plugin has been ported to Darwin.
823 * The `battery' plugin should work on many Apple computers now.
824 * The `traffic' plugin can now ignore certain interfaces. Also,
825 statistics for sent/received packets and errors have been added.
826 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
827 to Anthony Gialluca for contributing this plugin and providing me
828 with a test environment :)
829 * A plugin for monitoring an NTP instance and the local clock drift
832 2006-06-25, Version 3.9.4
833 * The Solaris code in the `swap' plugin has been changed to reflect
834 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
836 * The debugging system has been fixed to work with the Sun libc.
837 * When built without librrd the variable `operating_mode' could be
838 uninitialized. Thanks to David Elliot for reporting the bug.
840 2006-06-01, Version 3.9.3
841 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
842 operating systems also profit from the changes, but I wasn't able to
844 * Changed the build system to find the netinet-includes under FreeBSD
845 and therefore successfully build the `liboping' library there.
847 2006-05-09, Version 3.9.2
848 * Applied a patch to the `liboping' library. Due to a bug in the
849 sequence checking the `ping' plugin stopped working after
850 approximately 7.6 days.
852 2006-05-09, Version 3.8.5
853 * Applied a patch to the `liboping' library. Due to a bug in the
854 sequence checking the `ping' plugin stopped working after
855 approximately 7.6 days.
857 2006-04-21, Version 3.9.1
858 * Build issues with Solaris and possible other architectures have been
860 * Problems when building the `apache'-plugin without `libcurl' have
862 * A bug in the `ping' plugin has been fixed. Sorry folks.
864 2006-04-02, Version 3.9.0
865 * A plugin to monitor the Apache webserver has been added.
866 <http://httpd.apache.org/>
867 * A plugin to collect statistics about virtual servers using VServer.
868 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
870 * A plugin for wireless LAN cards has been added. It monitors signal
871 strength, link quality and noise ratio..
872 * A plugin for Apple hardware sensors has been added.
873 * An option to compile collectd with different `step' and `heartbeat'
874 settings has been added. The size of RRAs is no longer static but
875 calculated based on the settings for `step' and `width'.
876 * The `ping' plugin can now be configured to use a certain TTL.
877 * A plugin to monitor the hardware sensors of Apple computers has been
879 * The plugins `cpu', `memory', `processes' and `traffic' have been
880 ported to Mach/Darwin (Mac OS X).
881 * The `log mode' has been contributed by Christophe Kalt. It writes
882 the data into text files rather than RRD files.
884 2006-04-09, Version 3.8.4
885 * Applied patch by Vincent Stehlé which improves the disk-name
886 resolution in the `hddtemp' plugin for Linux systems.
888 2006-04-02, Version 3.8.3
889 * Applied a patch by James Byers: The MySQL plugin was not working
890 with MySQL 5.0.2 or later.
892 2006-03-14, Version 3.8.2
893 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
894 the GNU libc, because it points to `/etc/fstab' rather than
897 2006-03-13, Version 3.8.1
898 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
899 * Fixes in the debian `postinst' and `init.d' scripts.
901 2006-03-09, Version 3.8.0
902 * The `ping' plugin no longer uses `libping' but a self written
903 library named `liboping'. With this library it's possible to ping
904 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
906 2006-02-18, Version 3.7.2
907 * A simple bug in the `battery' plugin has been fixed. It should now
908 work with ACPI based batteries as well. Thanks to Sebastian for
910 * Fixing a bug that prevented collectd to be built without librrd.
911 Thanks to Werner Heuser for reporting it.
913 2006-02-04, Version 3.7.1
914 * The new network code has been improved to build with older versions
916 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
917 to Tommie Gannert for this patch.
919 2006-01-30, Version 3.7.0
920 * The `battery' plugin has been added. It collects information about
922 * The MySQL plugin has been improved: It now writes two more RRD
923 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
924 * The `cpufreq' plugin now reads another file since the file it did
925 read so far causes much overhead in the kernel. Also, you need root
926 to read the old file, but not to read the new one.
927 * The `hddtemp' plugin can now be configured to connect to another
928 address and/or port than localhost.
929 * The `df' plugin now prefers `statvfs' over `statfs'.
930 * The network code has been rewritten. collectd now supports unicast
931 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
932 be set in the configfile.
934 2006-01-24, Version 3.6.2
935 * Due to a bug in the configfile handling collectd wouldn't start in
936 client mode. This released fixes this.
938 2006-01-20, Version 3.6.1
939 * Due to a bug in `configure.in' all modules and the binary were
940 linked against `libmysqlclient'. This issue is solved by this
943 2006-01-17, Version 3.6.0
944 * A config file has been added. This allows for loading only specific
946 * A `df' plugin has been added.
947 * A `mysql' plugin has been added.
948 * The `ping' plugin doesn't entirely give up hope when a socket error
949 occurred, but will back of and increase the intervals between tries.
951 2006-01-21, Version 3.5.2
952 * Fixed yet another bug in the signal handling.. Stupid typo..
953 * Improved the ping plugin to not give up on socket errors (backport
956 2005-12-18, Version 3.5.1
957 * The PID-file is now deleted correctly when shutting down the daemon.
958 * SIGINT and SIGTERM are now handled correctly.
960 2005-12-16, Version 3.5.0 (Revision 326)
961 * A bug in the `load' module under Solaris has been fixed.
962 * The `users' module has been contributed by Sebastian Harl. It counts
963 currently logged in users.
964 * The CPU module now works under FreeBSD without the use of
965 `libstatgrab', however SMP support is missing.
966 * The default directories for the RRD files and the PID file now
967 depend on the compile time setting of `localstatedir'.
969 2005-11-15, Version 3.4.0 (Revision 236)
970 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
971 from gentoo's bugzilla for writing the patch.
972 * The build dependency for librrd has been removed. Binaries built
973 without librrd are client-only and will multicast their value as
974 with the `-c' argument.
975 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
976 * The newly introduced `-f' switch prevents daemon initialization
977 (forking, closing standard filehandles, etc.) Thanks to Alvaro
978 Barcellos for this patch.
980 2005-11-04, Version 3.3.0 (Revision 216)
981 * New modules have been added:
982 - `serial', for monitoring traffic on the serial interfaces
983 - `nfs', for graphing NFS procedure calls
984 - `tape', traffic from/to tape devices
985 * The memory.rrd now accepts more than 4Gig of memory.
987 2005-10-26, Version 3.2.0 (Revision 200)
988 * Support for graphing the processes has been added (thanks to Lyonel
990 * If reading from hddtemp fails collectd will increase the time
991 between polls up to one day.

993 * Problems with the spec file have been fixed.
995 2005-10-16, Version 3.1.0 (Revision 194)
996 * Added the `setsid' syscall to the startup code.
997 * Support for hddtemp has been added (thanks to Vincent Stehlé)
999 2005-09-30, Version 3.0.0 (Revision 184)
1000 * The ability to send/receive data to/from the network (think
1001 multicast) has been added.
1002 * Modules have been split up into shared libraries can be loaded at
1003 runtime. The biggest advantage is that the core program doesn't need
1004 to be linked against an external library.
1005 * A patch by George Kargiotakis has been applied: It fixes the sensors
1006 behaviour then more than one sensor is being queried.
1008 2005-09-16, Version 2.1.0 (Revision 172)
1009 * A module for swap statistics has been added.
1011 2005-09-09, Version 2.0.0 (Revision 135)
1012 * Filenames can no longer be configured at program startup. The only
1013 options as of this version are the directory and ping hosts.
1014 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1015 Soft-IRQ statistics are added to `System'.
1016 * Diskstats now collect read and write bytes, not sectors.
1017 * Ping statistics can now be collected for more than one host. There
1018 is no default any more: If no host is given no host will be pinged.
1019 * A self-written patch for libping has been applied so it builds
1022 2005-09-01, Version 1.8.1 (Revision 123)
1023 * Much improved configure-script: libraries and features may now be
1025 * More detailed warnings/error messages when RRD update fails.
1027 2005-08-29, Version 1.8.0:
1028 * Support for collecting disk statistics under Solaris.
1030 2005-08-25, Version 1.7.0:
1031 * Support for libstatgrab[1] for load, memory usage and network
1032 traffic. CPU- and disk-usage are not (yet) supported, since
1033 libstatgrab returns insufficient information. I will contact the
1035 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1036 aren't necessarily counted linear which is now handled correctly.

1039 2005-08-21, Version 1.6.0:
1040 * Basic support for Solaris: System load and cpu-usage can be
1041 collected under Solaris, too. Other stats will follow later.
1042 * Many fixes in the autoconf-script
1043 * Collection/Museum scripts have been added under contrib/museum
1044 * collectd may now be started in unprivileged mode, though ping
1045 statistics will not work.
1047 2005-07-17, Version 1.5.1:
1048 * Diskstats-RRDs now use major/minor for naming. Some systems have
1049 weird strings as disk-names..
1051 2005-07-17, Version 1.5:
1052 * A new module, diskstats, has been added. It collects information
1053 about the disks and partitions.
1055 2005-07-11, Version 1.4.2:
1056 * The meminfo module has been changed to work with more platforms
1057 and/or kernel versions.
1059 2005-07-10, Version 1.4.1: Correct traffic stats
1060 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1061 forgot to correct when I changed that module.
1063 2005-07-09, Version 1.4: More traffic stats
1064 * Traffic is now collected for all interfaces that can be found
1065 * Temperature-statistics are read from lm-sensors if available
1067 2005-07-08, Version 1.3: CPU stats
1068 * Collecting CPU statistics now
1070 2004-07-12, Version 1.2: Using syslog
1071 * collectd is now using the syslog facility to report errors, warnings
1073 * The default directory is now /var/db/collectd
1075 2004-07-10, Version 1.1: Minor changes
1076 * Nothing really useful to say ;)
1078 2004-07-09, Version 1.0: Initial Version
