68 * filter subsystem: Allow `Chains' without default targets.
69 * liboping: A patch to comply with strict aliasing rules has been
71 * timediff match: Fix a typo: The match was registered with a wrong
72 name which prevented this match to be used as documented. Thanks to
73 Bruno Prémont for finding this problem.
74 * bind plugin: Fix collection of the cached RR sets. The number of RR
75 sets currently in the cache was collected as a counter value, which
76 is nonsense. Thanks to Bruno Prémont for implementing this.
77 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
78 primarily BSDs, don't take it well and crash.
79 * oracle plugin: Portability to 64 bit systems has been improved.
80 * postgresql plugin: The default configuration has been improved.
81 * rrdtool plugin: Fix a possible race condition: If the network plugin

95 * collectd: Added the `filter chain' infrastructure, which allows the
96 user to use `matches' and `targets' to control value processing.
97 * collectd: The new `-T' command line argument allows more in-depth
98 testing of a configuration. Thanks to Doug MacEachern for the patch.
99 * collectd-nagios: The Nagios integration command has been updated to

116 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
117 example for native OpenBSD support, has been added. Thanks to Simon
118 Kuhnle for the patch.
119 * csv plugin: Make it possible to write values to STDOUT instead of
120 files. This is meant for testing purposes mostly. The output written
121 to STDOUT is compatible with the exec plugin. Thanks to Doug
122 MacEachern for the patch.
123 * curl plugin: This new plugin can be used to read web pages and parse
124 them using the same mechanism that's used in the tail plugin.
125 * dbi plugin: This new plugin allows you to connect to a variety of
126 relational databases and use SQL to gather custom statistics from
127 it. It is similar to the already existing PostgreSQL plugin but uses
128 libdbi to communicate with the database(s).
129 * interface plugin: Use the ignorelist framework when selecting /
130 ignoring interfaces. This allows one to use regular expressions to
131 select interfaces, too.
132 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
133 Thanks to Bruno Prémont for this patch.
134 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

150 allowing plugins to register `matches' and `targets'.
151 * postgresql plugin: The preferred configuration syntax has been
152 updated to be in line with the syntax used by the new dbi and oracle
153 plugins. The compatibility code for the old syntax is present.

156 * processes plugin: Stacksize and virtual memory usage statistics have
157 been added. Portability fixes.
158 * rrdcached plugin: This new plugin uses the (still in development)
159 RRD accelerator daemon, rrdcached. This daemon works very similar to
160 the original rrdtool plugin of collectd, but adds some more nice
162 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
165 2009-02-22, Version 4.5.3
166 * build system: The check for libupsclient even when `pkg-config' is
168 * collectd: Fix error handling in the global cache.

175 code. Thanks to "thated" for reporting this.
177 2009-01-02, Version 4.5.2
178 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
179 file may be in both locations, especially when the database was
180 installed in a non-standard path. Thanks to Dusty Doris for
182 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
183 Solaris, in the configure script automatically.
184 * build system, tcpconns plugin: Check for `kvm_nlist' and
185 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
186 library with similar functions to the BSD variant, but doesn't
187 provide these necessary functions.
188 * collectd.conf(5): Various fixes and clarifications.
189 * collectd: Remove a GNUism (unnamed unions), thus improving
191 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
192 This solves portability problems, especially for Solaris.
193 * dns plugin: Fix a portability problem with NetBSD.
194 * filecount plugin: Fix an off-by-one error. This error may cause a
196 * network plugin: Fix the handling of `type' in the network protocol.
197 Due to a programming mistake, only 4 or 8 bytes would be copied to a
198 much larger buffer. This caused the `type' to be transferred much
199 more often than necessary. In some cases, e. g. the `cpu' and
200 `cpufreq' plugins being used at the same time, data may be corrupted
201 in those files. Thanks to Bruno Prémont for debugging and reporting
203 * processes plugin: Fix a possible segmentation fault when specifying
204 invalid configuration options.
205 * unixsock plugin: Make sure the initialization function is run only
206 once. This resolves a file descriptor leak under systems which run
207 the initialization more than once, such as Solaris.
209 2008-10-16, Version 4.5.1
210 * build system: Change `--enable-<plugin>' to abort with an error if
211 dependencies are not met. Thanks to Bruno Prémont for the patch.
212 Also, the poisoning of various string functions has been restricted
214 * collectd: Fix a memory leak in the global value cache. With every
215 *missing* value a couple of bytes would be leaked. Another memory
216 leak in the configuration handling code has been fixed. Thanks to
217 Niraj Tolia for reporting these issues.
218 * collectd: Fix an off-by-one error in the ignorelist functionality.
219 When using regular expressions, the last character would be missing,
220 possibly matching differently from what one would expect.
221 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
223 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
224 Linzberger for reporting the bug.
225 * iptables plugin: Fix an off-by-one error. If a string was just one
226 character too long, it was truncated instead of reporting an error.
227 * network plugin: Fix a memory leak in the configuration handling
228 code. Thanks to Niraj Tolia for reporting this issue.
229 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
230 * postgresql plugin: Don't reopen connection during reinitialization.
231 This fixes a bug under Solaris and potentially other platforms.

233 leaks. Thanks to ``Admin'' for reporting these bugs.
234 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
236 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
237 problems with some `libc's. Thanks to Matthias Lay for reporting the
240 2008-09-04, Version 4.5.0
241 * collectd: Added the ability to flush certain identifiers.
242 * collectd: The concept of `notification meta data' has been
244 * filecount plugin: The new filecount plugin counts the number of
245 files in a directory and its subdirectories.
246 * ipmi plugin: Sensor names have been changed to ensure unique names.
247 Notifications upon added and removed sensors can now be generated.
248 * notify_desktop plugin: This new plugin sends notifications to the
249 X desktop using the structure defined in the `Desktop Notification
251 * notify_email plugin: This new plugin sends out notifications via
252 email, using the `esmtp' library.

254 such as temperatures, from sensors connected to the computer via the
256 * perl plugin: Improved synchronized access to internal data structures
257 and fixed a possible dead-lock.
258 * perl plugin: Added the ability to flush certain identifiers and marked
259 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
261 * perl plugin: Added the ability to configure Perl plugins.

269 using Linux ACPI thermal zone data.
271 2009-01-02, Version 4.4.5
272 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
273 file may be in both locations, especially when the database was
274 installed in a non-standard path. Thanks to Dusty Doris for
276 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
277 Solaris, in the configure script automatically.
278 * collectd.conf(5): Various fixes and clarifications.
279 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
280 portability problems, especially for Solaris.
281 * dns plugin: Fix a portability problem with NetBSD.
282 * network plugin: Fix the handling of `type' in the network protocol.
283 Due to a programming mistake, only 4 or 8 bytes would be copied to a
284 much larger buffer. This caused the `type' to be transferred much
285 more often than necessary. In some cases, e. g. the `cpu' and
286 `cpufreq' plugins being used at the same time, data may be corrupted
287 in those files. Thanks to Bruno Prémont for debugging and reporting
289 * unixsock plugin: Make sure the initialization function is run only
290 once. This resolves a file descriptor leak under systems which run
291 the initialization more than once, such as Solaris.
293 2008-10-16, Version 4.4.4
294 * build system: Change `--enable-<plugin>' to abort with an error if
295 dependencies are not met. Thanks to Bruno Prémont for the patch.
296 Also, the poisoning of various string functions has been restricted
298 * collectd: Fix a memory leak in the global value cache. With every

329 * dns plugin: Fix compilation errors with BIND versions 19991001
331 * network plugin: Bugfix in the init routine: The init function
332 cleared a buffer regardless of its contents. This could lead to lost
333 values under Solaris.
334 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
335 * vserver plugin: Remove usage of the thread-unsafe `readdir'
337 * wireless plugin: Work around incorrect noise and power values
338 returned by some broken drivers.
340 2008-06-03, Version 4.4.1

345 * collectd-nagios: Fix the protocol used to communicate with the
347 * perl plugin: Fail noisily, but don't shutdown the daemon, if
348 initialization has errors. An issue with Perl 5.10 has been fixed.
349 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
350 René Rebe and Siegmund Gorr for reporting this.
352 2008-05-06, Version 4.4.0
353 * collectd: Internal code cleanups.

443 * collectd: Threshold checking has been added to the daemon. This
444 means that you can configure threshold values for each data
445 instance. If this threshold is exceeded a notification will be
447 * collectd: The new `FQDNLookup' option tells the daemon to use the
448 full qualified domain name as the hostname, not just the host part
449 es returned by `gethostname(2)'.
450 * collectd: Support for more than one `TypesDB' file has been added.
451 This is useful when one such file is included in a package but one
452 wants to add custom type definitions.
453 * collectd: The `Include' config option has been expanded to handle
454 entire directories and shell wildcards.
455 * collectdmon: The new `collectdmon' binary detects when collectd
456 terminates and automatically restarts it again.

465 domain name lookups in this plugin.
466 * perl plugin: Many internal changes added support for handling multiple
467 threads making the plugin reasonably usable inside collectd. The API has
468 been extended to support notifications and export global variables to
469 Perl plugins; callbacks now have to be identified by name rather than a
470 pointer to a subroutine. The plugin is no longer experimental.
471 * uuid plugin: The new UUID plugin sets the hostname to an unique
472 identifier for this host. This is meant for setups where each client
473 may migrate to another physical host, possibly going through one or
474 more name changes in the process. Thanks to Richard Jones from
475 Red Hat's Emerging Technology group for this plugin.
476 * libvirt: The new libvirt plugin uses the `libvirt' library to query
477 CPU, disk and network statistics about guest systems on the same
478 physical server. Thanks to Richard Jones from Red Hat's Emerging
479 Technology group for this plugin.
481 2008-04-22, Version 4.2.7

506 + Create separate threads for reading from the socket and parsing
507 and dispatching incoming packets. Versions prior to this may have
508 problems in high-load situations, where the socket receive buffers
509 overflows, resulting in gaps in the data.
510 + Use `memcpy' when constructing/parsing a package to avoid
511 alignment problems on weird architectures, such as Sparc.
512 + Translate doubles to/from the x86 byte representation to ensure
513 cross-platform compatibility.
514 * ping plugin: Correct the handling of the `TTL' setting.
515 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
516 * swap plugin: Reapply a patch for Solaris.
517 * tcpconns plugin: Portability improvements.
519 2008-01-21, Version 4.2.4
520 * unixsock plugin: A bug in the unixsock plugin caused it not to set
521 the permission on the socket as documented in the manpage. Thanks to
522 Evgeny Chukreev for fixing this issue.
523 * collectd: The documentation has been improved.
525 2007-12-28, Version 4.2.3
526 * sensors plugin: Updated the plugin to build and work with version 3
527 of the libsensors library.
529 2007-12-15, Version 4.2.2
530 * nginx plugin: Incorrect comparison of strings lead to a segfault
531 when using the plugin. Thanks to Saulius Grigaliunas for fixing
533 * logfile plugin: The config option `Timestamp' was handled
534 incorrectly and basically always active. Thanks to Luke Heberling
537 2007-11-08, Version 4.2.1
538 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
540 * snmp plugin: Fix a memory leak.
542 2007-10-27, Version 4.2.0
543 * collectd: The new config option `Include' lets you include other
544 configfiles and thus split up your config into smaller parts. This
545 may be especially interesting for the snmp plugin to keep the data
546 definitions separate from the host definitions.
547 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
548 (number of connections, octets and packets for each service and
549 destination). Thanks to Sebastian Harl for this plugin.
550 * memcached plugin: The new `memcached' plugin connects to a memcached
551 daemon process and collects statistics of this distributed caching
552 system. Thanks to Antony Dovgal for contributing this plugin.
553 * nginx plugin: The new `nginx' plugin reads the status page of an
554 nginx daemon and saves the handled connections and requests.
555 * perl plugin: Many changes, including the added `EnableDebugger'
556 config option which lets you debug your Perl plugins more easily.
557 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
558 be more thread-safe otherwise by locking calls to the library.
559 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
560 correct the values returned by SNMP-agents. If a <data> block is
561 defined as `table' the instance is now optional. The sequence number
562 is used as the type-instance in this case. The new `InstancePrefix'
563 option allows to add arbitrary prefixes to the type-instance.
564 * tcpconns plugin: The new `tcpconns' plugin collects the number of
565 certain TCP connections and what state they're in. This can be used
566 to see how many connections your FTP server has to handle or how
567 many outgoing connections your mailserver has open.
569 2008-01-11, Version 4.1.6
570 * unixsock plugin: A bug in the unixsock plugin caused it not to set
571 the permission on the socket as documented in the manpage. Thanks to
572 Evgeny Chukreev for fixing this issue.
573 * collectd: The documentation has been improved.
575 2007-12-27, Version 4.1.5

579 of the libsensors library.
581 2007-11-08, Version 4.1.4
582 * Build system: Improve detection of the rrd library, especially if
583 it's in a non-standard location.
584 * Build system: A bug when parsing the argument for
585 `--with-libnetsnmp' has been fixed.
586 * collectd: Implement `strerror_r' if the libc doesn't provide it.
587 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
588 a deadlock or delay when shutting down the daemon.
589 * snmp plugin: Fix a memory leak.
591 2007-10-24, Version 4.1.3
592 * collectd: A build issue under Solaris has been resolved by renaming
594 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
595 be more thread-safe otherwise by locking calls to the library.
597 2007-09-28, Version 4.1.2
598 * apcups plugin: Fix reporting of the `load percent' data.
599 * wireless plugin: Correct the handling of cards returning signal and
600 noise quality as percentage.
601 * perl plugin: Fix a possible buffer overflow in get_module_name().
602 * build system: Further improve the detection of libraries.
603 * netlink plugin: Build issues under some older versions of the Linux
604 includes (i. e. Debian Sarge) have been fixed.

609 * Build system: The detection of `libnetlink' has been improved.
610 * collectd: The documentation has been fixed in numerous places.
611 * exec plugin: Setting the group under which to run a program has been
613 * collectd: The `sstrerror' function was improved to work correctly
614 with the broken GNU version of `strerror_r'.
615 * collectd: Write an error message to STDERR when loading of a plugin
617 * apcups plugin: Fix the `types' used to submit the values: They still
618 has an `apcups_' prefix which doesn't work anymore.
619 * rrdtool plugin: Create new RRD-files with the `begin' time set to
620 whatever the client thinks is `now'..
622 2007-09-01, Version 4.1.0
623 * Build system: The build system has been changed to automatically
624 disable all plugins, which are missing dependencies. The dependency
625 checking has been removed from the plugins themselves to remove
627 * Flexible interval: The interval of collected data is now sent along
628 with the data itself over the network, so that the interval-settings
629 of server and clients no longer needs to match.
630 * netlink plugin: The new `netlink' plugin connects to the Linux
631 kernel using a netlink socket and uses it to query information about
632 interfaces, qdiscs and classes.
633 * rrdtool plugin: The cache is now dumped to disk in an extra thread
634 to not block data collection.
635 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
636 network devices, such as switches, routers, thermometers, rack
637 monitoring servers, etc. The collectd-snmp(5) manpage documents this
639 * unixsock plugin: Added the `LISTVAL' command.
640 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
641 of music played with xmms.
643 2007-09-28, Version 4.0.9
644 * apcups plugin: Fix reporting of the `load percent' data.
645 * wireless plugin: Correct the handling of cards returning signal and
646 noise quality as percentage.
647 * perl plugin: Fix a possible buffer overflow in get_module_name().
649 2007-09-12, Version 4.0.8
650 * collectd: The `sstrerror' function was improved to work correctly
651 with the broken GNU version of `strerror_r'.
652 * collectd: Write an error message to STDERR when loading of a plugin
654 * apcups plugin: Fix the `types' used to submit the values: They still
655 has an `apcups_' prefix which doesn't work anymore.
656 * rrdtool plugin: Create new RRD-files with the `begin' time set to
657 whatever the client thinks is `now'..
659 2007-08-26, Version 4.0.7
660 * documentation: Some typos have been fixed and some information has
662 * build system: Many fixes for detecting libraries in unusual places,
663 such as on RedHat systems. The affected libraries are `libcurl',
664 `libmysql', and `libupsclient'.
665 * network plugin: Allow the `Port' option to be specified as a number
666 (i. e. without quotes).
667 * nut plugin: A fix allows linking the nut plugin against
668 libupsclient, version >= 2.2.0.
669 * processes plugin: Fix a potential segmentation fault.
671 2007-07-30, Version 4.0.6
672 * sensors plugin: Fix the ignorelist functionality: Only the `type
673 instance' was used to match against the list, but the documentation
674 told otherwise. This release fixes the code, so it complies with the
676 * syslog plugin: Call `openlog' right when the plugin is loaded, so
677 configuration messages will end up in the logging facility.
678 * conrtib/fedora: The contributed specfile for Fedora has been
681 2007-07-05, Version 4.0.5
682 * Portability: More fixes for OpenBSD have been included.
684 2007-06-24, Version 4.0.4
685 * cpu plugin: Fixed the Solaris code.
686 * dns plugin: Fixed a build issue for OpenBSD.
687 * interface plugin: Fixed the Solaris code.
688 * load plugin: Fixed the alternative `/proc' Linux code.

701 they're given in numerically form.
703 2007-06-07, Version 4.0.1
704 * iptables plugin: A bug in the configuration routine has been fixed.
705 Setting a comment in the configfile will no longer cause a
708 2007-06-03, Version 4.0.0
709 * collectd: The plugin-infrastructure has been changed to allow for
710 more types of plugins, namely `write' and `log' plugins.
711 * collectd: The read-function has been changed to read many plugins in
712 parallel, using threads. Thus, plugins generally need to use
713 thread-safe functions from now on.
714 * collectd: The '-t' command line options allows to perform syntax tests
715 of the configuration file and exit immediately.
716 * csv plugin: The new `csv' plugin handles output to `comma separated
718 * rrdtool plugin: The new `rrdtool' plugin handles output to
719 RRD-files. Data can be cached to combine multiple updates into one
720 write to increase IO-performance.
721 * network plugin: The new `network' plugin handles IO via the network.
722 It implements a different, much more extensible protocol which can
723 combine many values in one packet, decreasing the number of UDP-
724 packets being sent. It can read from and send to the network and
725 with the appropriate configuration even forward packets to other
727 * unixsock plugin: The new `unixsock' plugin provides an interface to
728 communicate with the daemon while it is running. Right now the
729 commands `GETVAL' and `PUTVAL' are implemented, but more are to
731 * perl plugin: The new `perl' plugin allows you to write extensions
732 for collectd in the scripting-language Perl.
733 * logfile plugin: The new `logfile' plugin writes logmessages to files
735 * syslog plugin: The new `syslog' plugin sends logmessages to the
736 system's syslog daemon.
737 * entropy plugin: The new `entropy' plugin collects the amount of
738 entropy currently being available to the system.
739 * exec plugin: The new `exec' plugin forks child processes and reads
740 back values provided by the forked processes.
741 * iptables plugin: The new `iptables' plugin reads counters from
742 iptables rules. Thanks to Sjoerd van der Berg for contributing this
744 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
745 to Peter Holik for contributing this plugin.
746 * nut plugin: The new `nut' plugin connects the upsd of the `network
747 ups tools' and reads information about the connected UPS.
748 * apache plugin: Support for lighttpd's `BusyServers' (aka.
749 connections) field was added by Florent Monbillard.
750 * collectd-nagios: The new `collectd-nagios' binary queries values
751 from collectd, parses them and exits according to Nagios-standards.
752 * manpages: The manpages have been improved a lot.
754 2007-09-28, Version 3.11.7
755 * wireless plugin: Correct the handling of cards returning signal and
756 noise quality as percentage.
758 2007-08-31, Version 3.11.6

762 * configure: Added `AC_SYS_LARGEFILE' for LFS.
763 * ntpd plugin: Fix a potential buffer overflow.
764 * processes plugin: Fix a bug when run under Linux 2.4. All processes
765 were accounted as `zombies'.
767 2007-04-10, Version 3.11.4
768 * dns plugin: Change the order of includes to make the plugin compile
771 2007-03-30, Version 3.11.3
772 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
773 of the unused `COLLECT_KSTAT'.
775 2007-02-11, Version 3.11.2
776 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
777 NULL-pointer may have been passed to `printf' which causes a
778 segfault with some libcs.
780 2007-02-10, Version 3.11.1
781 * df plugin: Some wrong defines have been fixed so the plugin works
783 * dns plugin: The usage of a struct has been fixed to work with
785 * processes plugin: Some missing defines have been added so the plugin
786 compiles cleanly under FreeBSD and presumably other UNIXes.
788 2006-12-22, Version 3.11.0
789 * collectd: The new command line option `-P' makes it easier for
790 distributors to change the location of PID-files.
791 * collectd: The daemon shuts down faster now which makes it easier to
792 write init.d-scripts for it.
793 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
794 caused problems every now and then.
795 * df plugin: New config options allow to ignore certain mountpoints,
796 filesystem types or devices.
797 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
798 and interprets it. It collects traffic as well as qtype, opcode and
800 * email plugin: Sebastian Harl has contributed this plugin which
801 counts received mails in categories (e. g. ham, spam, virus), spam
802 score (as given by SpamAssassin) and check types.
803 * mbmon plugin: Flavio Stanchina has contributed this plugin which
804 uses `mbmon' to gather information from sensors on the motherboard.
805 * processes plugin: Collect detailed statistics for configured
806 processes, that's process and thread count, CPU usage, resident
807 segment size and pagefaults.
808 * multimeter plugin: Peter Holik contributed a new plugin which
810 * sensors plugin: Lubos Stanek has put much effort into improving this
811 plugin, including `extended naming', collection of voltage values
812 and the possibility to ignore certain values.
814 2006-12-21, Version 3.10.4
815 * Max Kellermann has identified a bug in the server routine: When
816 opening a socket fails the daemon will (re)try opening the socket in
817 an endless loop, ultimately leading to a `EMFILE' error.
819 2006-11-04, Version 3.10.3
820 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
821 ntpd's reply was sent in more than one packet, the buffer size was
822 calculated incorrectly, resulting in the reading of uninitialized or
825 2006-11-01, Version 3.10.2
826 * The sample config file has been improved.
827 * Errors in the manpages have been corrected.
828 * The ping-plugin now adds hosts during initialization, not during
829 startup. This speeds up startup when no network connectivity is
830 available. Also, the hosts are being added later when the network is
832 * Improved BSD-support for the df-plugin.
833 * Fixed syntax errors in the swap-plugin for Mac OS X.
834 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
836 * Don't disable the mysql-plugin if connecting to the database fails
837 during initialization. Instead, try again in increasing intervals.
839 2006-07-19, Version 3.10.1
840 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
841 the apcups cannot be reached, unconnected sockets will pile up and
842 eventually lead to `Too many open files' errors.
844 2006-07-09, Version 3.10.0
845 * The `disk' plugin has been ported to Darwin.
846 * The `battery' plugin should work on many Apple computers now.
847 * The `traffic' plugin can now ignore certain interfaces. Also,
848 statistics for sent/received packets and errors have been added.
849 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
850 to Anthony Gialluca for contributing this plugin and providing me
851 with a test environment :)
852 * A plugin for monitoring an NTP instance and the local clock drift
855 2006-06-25, Version 3.9.4
856 * The Solaris code in the `swap' plugin has been changed to reflect
857 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
859 * The debugging system has been fixed to work with the Sun libc.
860 * When built without librrd the variable `operating_mode' could be
861 uninitialized. Thanks to David Elliot for reporting the bug.
863 2006-06-01, Version 3.9.3
864 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
865 operating systems also profit from the changes, but I wasn't able to
867 * Changed the build system to find the netinet-includes under FreeBSD
868 and therefore successfully build the `liboping' library there.
870 2006-05-09, Version 3.9.2
871 * Applied a patch to the `liboping' library. Due to a bug in the
872 sequence checking the `ping' plugin stopped working after
873 approximately 7.6 days.
875 2006-05-09, Version 3.8.5
876 * Applied a patch to the `liboping' library. Due to a bug in the
877 sequence checking the `ping' plugin stopped working after
878 approximately 7.6 days.
880 2006-04-21, Version 3.9.1
881 * Build issues with Solaris and possible other architectures have been
883 * Problems when building the `apache'-plugin without `libcurl' have
885 * A bug in the `ping' plugin has been fixed. Sorry folks.
887 2006-04-02, Version 3.9.0
888 * A plugin to monitor the Apache webserver has been added.
889 <http://httpd.apache.org/>
890 * A plugin to collect statistics about virtual servers using VServer.
891 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
893 * A plugin for wireless LAN cards has been added. It monitors signal
894 strength, link quality and noise ratio..
895 * A plugin for Apple hardware sensors has been added.
896 * An option to compile collectd with different `step' and `heartbeat'
897 settings has been added. The size of RRAs is no longer static but
898 calculated based on the settings for `step' and `width'.
899 * The `ping' plugin can now be configured to use a certain TTL.
900 * A plugin to monitor the hardware sensors of Apple computers has been
902 * The plugins `cpu', `memory', `processes' and `traffic' have been
903 ported to Mach/Darwin (Mac OS X).
904 * The `log mode' has been contributed by Christophe Kalt. It writes
905 the data into text files rather than RRD files.
907 2006-04-09, Version 3.8.4
908 * Applied patch by Vincent Stehlé which improves the disk-name
909 resolution in the `hddtemp' plugin for Linux systems.
911 2006-04-02, Version 3.8.3
912 * Applied a patch by James Byers: The MySQL plugin was not working
913 with MySQL 5.0.2 or later.
915 2006-03-14, Version 3.8.2
916 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
917 the GNU libc, because it points to `/etc/fstab' rather than
920 2006-03-13, Version 3.8.1
921 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
922 * Fixes in the debian `postinst' and `init.d' scripts.
924 2006-03-09, Version 3.8.0
925 * The `ping' plugin no longer uses `libping' but a self written
926 library named `liboping'. With this library it's possible to ping
927 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
929 2006-02-18, Version 3.7.2
930 * A simple bug in the `battery' plugin has been fixed. It should now
931 work with ACPI based batteries as well. Thanks to Sebastian for
933 * Fixing a bug that prevented collectd to be built without librrd.
934 Thanks to Werner Heuser for reporting it.
936 2006-02-04, Version 3.7.1
937 * The new network code has been improved to build with older versions
939 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
940 to Tommie Gannert for this patch.
942 2006-01-30, Version 3.7.0
943 * The `battery' plugin has been added. It collects information about
945 * The MySQL plugin has been improved: It now writes two more RRD
946 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
947 * The `cpufreq' plugin now reads another file since the file it did
948 read so far causes much overhead in the kernel. Also, you need root
949 to read the old file, but not to read the new one.
950 * The `hddtemp' plugin can now be configured to connect to another
951 address and/or port than localhost.
952 * The `df' plugin now prefers `statvfs' over `statfs'.
953 * The network code has been rewritten. collectd now supports unicast
954 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
955 be set in the configfile.
957 2006-01-24, Version 3.6.2
958 * Due to a bug in the configfile handling collectd wouldn't start in
959 client mode. This released fixes this.
961 2006-01-20, Version 3.6.1
962 * Due to a bug in `configure.in' all modules and the binary were
963 linked against `libmysqlclient'. This issue is solved by this
966 2006-01-17, Version 3.6.0
967 * A config file has been added. This allows for loading only specific
969 * A `df' plugin has been added.
970 * A `mysql' plugin has been added.
971 * The `ping' plugin doesn't entirely give up hope when a socket error
972 occurred, but will back of and increase the intervals between tries.
974 2006-01-21, Version 3.5.2
975 * Fixed yet another bug in the signal handling.. Stupid typo..
976 * Improved the ping plugin to not give up on socket errors (backport
979 2005-12-18, Version 3.5.1
980 * The PID-file is now deleted correctly when shutting down the daemon.
981 * SIGINT and SIGTERM are now handled correctly.
983 2005-12-16, Version 3.5.0 (Revision 326)
984 * A bug in the `load' module under Solaris has been fixed.
985 * The `users' module has been contributed by Sebastian Harl. It counts
986 currently logged in users.
987 * The CPU module now works under FreeBSD without the use of
988 `libstatgrab', however SMP support is missing.
989 * The default directories for the RRD files and the PID file now
990 depend on the compile time setting of `localstatedir'.
992 2005-11-15, Version 3.4.0 (Revision 236)
993 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
994 from gentoo's bugzilla for writing the patch.
995 * The build dependency for librrd has been removed. Binaries built
996 without librrd are client-only and will multicast their value as
997 with the `-c' argument.
998 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
999 * The newly introduced `-f' switch prevents daemon initialization
1000 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1001 Barcellos for this patch.
1003 2005-11-04, Version 3.3.0 (Revision 216)
1004 * New modules have been added:
1005 - `serial', for monitoring traffic on the serial interfaces
1006 - `nfs', for graphing NFS procedure calls
1007 - `tape', traffic from/to tape devices
1008 * The memory.rrd now accepts more than 4Gig of memory.
1010 2005-10-26, Version 3.2.0 (Revision 200)
1011 * Support for graphing the processes has been added (thanks to Lyonel
1013 * If reading from hddtemp fails collectd will increase the time
1014 between polls up to one day.
1015 * The init.d files have been improved.
1016 * Problems with the spec file have been fixed.
1018 2005-10-16, Version 3.1.0 (Revision 194)
1019 * Added the `setsid' syscall to the startup code.
1020 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1022 2005-09-30, Version 3.0.0 (Revision 184)
1023 * The ability to send/receive data to/from the network (think
1024 multicast) has been added.
1025 * Modules have been split up into shared libraries can be loaded at
1026 runtime. The biggest advantage is that the core program doesn't need
1027 to be linked against an external library.
1028 * A patch by George Kargiotakis has been applied: It fixes the sensors
1029 behaviour then more than one sensor is being queried.
1031 2005-09-16, Version 2.1.0 (Revision 172)
1032 * A module for swap statistics has been added.
1034 2005-09-09, Version 2.0.0 (Revision 135)
1035 * Filenames can no longer be configured at program startup. The only
1036 options as of this version are the directory and ping hosts.
1037 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1038 Soft-IRQ statistics are added to `System'.
1039 * Diskstats now collect read and write bytes, not sectors.
1040 * Ping statistics can now be collected for more than one host. There
1041 is no default any more: If no host is given no host will be pinged.
1042 * A self-written patch for libping has been applied so it builds
1045 2005-09-01, Version 1.8.1 (Revision 123)
1046 * Much improved configure-script: libraries and features may now be
1048 * More detailed warnings/error messages when RRD update fails.
1050 2005-08-29, Version 1.8.0:
1051 * Support for collecting disk statistics under Solaris.
1053 2005-08-25, Version 1.7.0:
1054 * Support for libstatgrab[1] for load, memory usage and network
1055 traffic. CPU- and disk-usage are not (yet) supported, since
1056 libstatgrab returns insufficient information. I will contact the
1058 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1059 aren't necessarily counted linear which is now handled correctly.
1060 [1]: http://www.i-scream.org/libstatgrab/
1062 2005-08-21, Version 1.6.0:
1063 * Basic support for Solaris: System load and cpu-usage can be
1064 collected under Solaris, too. Other stats will follow later.
1065 * Many fixes in the autoconf-script
1066 * Collection/Museum scripts have been added under contrib/museum
1067 * collectd may now be started in unprivileged mode, though ping
1068 statistics will not work.
1070 2005-07-17, Version 1.5.1:
1071 * Diskstats-RRDs now use major/minor for naming. Some systems have
1072 weird strings as disk-names..
1074 2005-07-17, Version 1.5:
1075 * A new module, diskstats, has been added. It collects information
1076 about the disks and partitions.
1078 2005-07-11, Version 1.4.2:
1079 * The meminfo module has been changed to work with more platforms
1080 and/or kernel versions.
1082 2005-07-10, Version 1.4.1: Correct traffic stats
1083 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1084 forgot to correct when I changed that module.
1086 2005-07-09, Version 1.4: More traffic stats
1087 * Traffic is now collected for all interfaces that can be found
1088 * Temperature-statistics are read from lm-sensors if available
1090 2005-07-08, Version 1.3: CPU stats
1091 * Collecting CPU statistics now
1093 2004-07-12, Version 1.2: Using syslog
1094 * collectd is now using the syslog facility to report errors, warnings
1096 * The default directory is now /var/db/collectd
1098 2004-07-10, Version 1.1: Minor changes
1099 * Nothing really useful to say ;)
1101 2004-07-09, Version 1.0: Initial Version
1102 * The following modules are provided:
