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.
18 * memcached plugin: Support for connections over UNIX domain sockets
19 has been added. Thanks to Franck Lombardi for the patch.

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

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

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

120 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
121 * oracle plugin: This new plugin allows you to connect to an Oracle
122 database and use SQL to gather custom statistics from it. It is
123 similar to the already existing PostgreSQL plugin.
124 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
126 * perl plugin: Export the newly added plugin_write() to Perl plugins.
127 * perl plugin: Added support for `notification meta data'.
128 * perl plugin: Added support for the `filter chain' infrastructure by
129 allowing plugins to register `matches' and `targets'.
130 * postgresql plugin: The preferred configuration syntax has been
131 updated to be in line with the syntax used by the new dbi and oracle
132 plugins. The compatibility code for the old syntax is present.
133 Support for the new `Result' blocks and the interval parameter has
135 * processes plugin: Stacksize and virtual memory usage statistics have
136 been added. Portability fixes.
137 * rrdcached plugin: This new plugin uses the (still in development)
138 RRD accelerator daemon, rrdcached. This daemon works very similar to
139 the original rrdtool plugin of collectd, but adds some more nice
141 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
144 2009-02-22, Version 4.5.3
145 * build system: The check for libupsclient even when `pkg-config' is
147 * collectd: Fix error handling in the global cache.
148 * Collectd::Unixsock: Error handling has been improved.
149 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

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

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

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

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

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

421 are status messages that may be associated with a data instance.
422 * collectd: Threshold checking has been added to the daemon. This
423 means that you can configure threshold values for each data
424 instance. If this threshold is exceeded a notification will be
426 * collectd: The new `FQDNLookup' option tells the daemon to use the
427 full qualified domain name as the hostname, not just the host part
428 es returned by `gethostname(2)'.
429 * collectd: Support for more than one `TypesDB' file has been added.
430 This is useful when one such file is included in a package but one
431 wants to add custom type definitions.
432 * collectd: The `Include' config option has been expanded to handle
433 entire directories and shell wildcards.
434 * collectdmon: The new `collectdmon' binary detects when collectd
435 terminates and automatically restarts it again.
436 * csv plugin: The CSV plugin is now able to store counter values as a
437 rate, using the `StoreRates' configuration option.
438 * exec plugin: Handling of notifications has been added and the
439 ability to pass arguments to the executed programs has been added.
440 * hddtemp plugin: The new `TranslateDevicename' option lets you
441 disable the translation from device names to major-minor-numbers.
442 * logfile plugin: Handling of notifications has been added.
443 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
444 domain name lookups in this plugin.
445 * perl plugin: Many internal changes added support for handling multiple
446 threads making the plugin reasonably usable inside collectd. The API has
447 been extended to support notifications and export global variables to
448 Perl plugins; callbacks now have to be identified by name rather than a
449 pointer to a subroutine. The plugin is no longer experimental.
450 * uuid plugin: The new UUID plugin sets the hostname to an unique
451 identifier for this host. This is meant for setups where each client
452 may migrate to another physical host, possibly going through one or
453 more name changes in the process. Thanks to Richard Jones from
454 Red Hat's Emerging Technology group for this plugin.
455 * libvirt: The new libvirt plugin uses the `libvirt' library to query
456 CPU, disk and network statistics about guest systems on the same
457 physical server. Thanks to Richard Jones from Red Hat's Emerging
458 Technology group for this plugin.
460 2008-04-22, Version 4.2.7
461 * build system: Improved detection of several libraries, especially if

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

500 the permission on the socket as documented in the manpage. Thanks to
501 Evgeny Chukreev for fixing this issue.
502 * collectd: The documentation has been improved.
504 2007-12-28, Version 4.2.3
505 * sensors plugin: Updated the plugin to build and work with version 3
506 of the libsensors library.
508 2007-12-15, Version 4.2.2
509 * nginx plugin: Incorrect comparison of strings lead to a segfault
510 when using the plugin. Thanks to Saulius Grigaliunas for fixing
512 * logfile plugin: The config option `Timestamp' was handled
513 incorrectly and basically always active. Thanks to Luke Heberling
516 2007-11-08, Version 4.2.1
517 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
519 * snmp plugin: Fix a memory leak.
521 2007-10-27, Version 4.2.0
522 * collectd: The new config option `Include' lets you include other
523 configfiles and thus split up your config into smaller parts. This
524 may be especially interesting for the snmp plugin to keep the data
525 definitions separate from the host definitions.
526 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
527 (number of connections, octets and packets for each service and
528 destination). Thanks to Sebastian Harl for this plugin.
529 * memcached plugin: The new `memcached' plugin connects to a memcached
530 daemon process and collects statistics of this distributed caching
531 system. Thanks to Antony Dovgal for contributing this plugin.
532 * nginx plugin: The new `nginx' plugin reads the status page of an
533 nginx daemon and saves the handled connections and requests.
534 * perl plugin: Many changes, including the added `EnableDebugger'
535 config option which lets you debug your Perl plugins more easily.
536 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
537 be more thread-safe otherwise by locking calls to the library.
538 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
539 correct the values returned by SNMP-agents. If a <data> block is
540 defined as `table' the instance is now optional. The sequence number
541 is used as the type-instance in this case. The new `InstancePrefix'
542 option allows to add arbitrary prefixes to the type-instance.
543 * tcpconns plugin: The new `tcpconns' plugin collects the number of
544 certain TCP connections and what state they're in. This can be used
545 to see how many connections your FTP server has to handle or how
546 many outgoing connections your mailserver has open.
548 2008-01-11, Version 4.1.6
549 * unixsock plugin: A bug in the unixsock plugin caused it not to set
550 the permission on the socket as documented in the manpage. Thanks to
551 Evgeny Chukreev for fixing this issue.
552 * collectd: The documentation has been improved.
554 2007-12-27, Version 4.1.5
555 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

558 of the libsensors library.
560 2007-11-08, Version 4.1.4
561 * Build system: Improve detection of the rrd library, especially if
562 it's in a non-standard location.
563 * Build system: A bug when parsing the argument for
564 `--with-libnetsnmp' has been fixed.
565 * collectd: Implement `strerror_r' if the libc doesn't provide it.
566 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
567 a deadlock or delay when shutting down the daemon.
568 * snmp plugin: Fix a memory leak.
570 2007-10-24, Version 4.1.3
571 * collectd: A build issue under Solaris has been resolved by renaming
573 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
574 be more thread-safe otherwise by locking calls to the library.
576 2007-09-28, Version 4.1.2
577 * apcups plugin: Fix reporting of the `load percent' data.
578 * wireless plugin: Correct the handling of cards returning signal and
579 noise quality as percentage.
580 * perl plugin: Fix a possible buffer overflow in get_module_name().
581 * build system: Further improve the detection of libraries.
582 * netlink plugin: Build issues under some older versions of the Linux
583 includes (i. e. Debian Sarge) have been fixed.
584 * snmp plugin: Fix a potential segfault when a host times out. Add
585 support for the `timeticks' type.

588 * Build system: The detection of `libnetlink' has been improved.
589 * collectd: The documentation has been fixed in numerous places.
590 * exec plugin: Setting the group under which to run a program has been
592 * collectd: The `sstrerror' function was improved to work correctly
593 with the broken GNU version of `strerror_r'.
594 * collectd: Write an error message to STDERR when loading of a plugin
596 * apcups plugin: Fix the `types' used to submit the values: They still
597 has an `apcups_' prefix which doesn't work anymore.
598 * rrdtool plugin: Create new RRD-files with the `begin' time set to
599 whatever the client thinks is `now'..
601 2007-09-01, Version 4.1.0
602 * Build system: The build system has been changed to automatically
603 disable all plugins, which are missing dependencies. The dependency
604 checking has been removed from the plugins themselves to remove
606 * Flexible interval: The interval of collected data is now sent along
607 with the data itself over the network, so that the interval-settings
608 of server and clients no longer needs to match.
609 * netlink plugin: The new `netlink' plugin connects to the Linux
610 kernel using a netlink socket and uses it to query information about
611 interfaces, qdiscs and classes.
612 * rrdtool plugin: The cache is now dumped to disk in an extra thread
613 to not block data collection.
614 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
615 network devices, such as switches, routers, thermometers, rack
616 monitoring servers, etc. The collectd-snmp(5) manpage documents this
618 * unixsock plugin: Added the `LISTVAL' command.
619 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
620 of music played with xmms.
622 2007-09-28, Version 4.0.9
623 * apcups plugin: Fix reporting of the `load percent' data.
624 * wireless plugin: Correct the handling of cards returning signal and
625 noise quality as percentage.
626 * perl plugin: Fix a possible buffer overflow in get_module_name().
628 2007-09-12, Version 4.0.8
629 * collectd: The `sstrerror' function was improved to work correctly
630 with the broken GNU version of `strerror_r'.
631 * collectd: Write an error message to STDERR when loading of a plugin
633 * apcups plugin: Fix the `types' used to submit the values: They still
634 has an `apcups_' prefix which doesn't work anymore.
635 * rrdtool plugin: Create new RRD-files with the `begin' time set to
636 whatever the client thinks is `now'..
638 2007-08-26, Version 4.0.7
639 * documentation: Some typos have been fixed and some information has
641 * build system: Many fixes for detecting libraries in unusual places,
642 such as on RedHat systems. The affected libraries are `libcurl',
643 `libmysql', and `libupsclient'.
644 * network plugin: Allow the `Port' option to be specified as a number
645 (i. e. without quotes).
646 * nut plugin: A fix allows linking the nut plugin against
647 libupsclient, version >= 2.2.0.
648 * processes plugin: Fix a potential segmentation fault.
650 2007-07-30, Version 4.0.6
651 * sensors plugin: Fix the ignorelist functionality: Only the `type
652 instance' was used to match against the list, but the documentation
653 told otherwise. This release fixes the code, so it complies with the
655 * syslog plugin: Call `openlog' right when the plugin is loaded, so
656 configuration messages will end up in the logging facility.
657 * conrtib/fedora: The contributed specfile for Fedora has been
660 2007-07-05, Version 4.0.5
661 * Portability: More fixes for OpenBSD have been included.
663 2007-06-24, Version 4.0.4
664 * cpu plugin: Fixed the Solaris code.

680 they're given in numerically form.
682 2007-06-07, Version 4.0.1
683 * iptables plugin: A bug in the configuration routine has been fixed.
684 Setting a comment in the configfile will no longer cause a
687 2007-06-03, Version 4.0.0
688 * collectd: The plugin-infrastructure has been changed to allow for
689 more types of plugins, namely `write' and `log' plugins.
690 * collectd: The read-function has been changed to read many plugins in
691 parallel, using threads. Thus, plugins generally need to use
692 thread-safe functions from now on.
693 * collectd: The '-t' command line options allows to perform syntax tests
694 of the configuration file and exit immediately.
695 * csv plugin: The new `csv' plugin handles output to `comma separated
697 * rrdtool plugin: The new `rrdtool' plugin handles output to
698 RRD-files. Data can be cached to combine multiple updates into one
699 write to increase IO-performance.
700 * network plugin: The new `network' plugin handles IO via the network.
701 It implements a different, much more extensible protocol which can
702 combine many values in one packet, decreasing the number of UDP-
703 packets being sent. It can read from and send to the network and
704 with the appropriate configuration even forward packets to other
706 * unixsock plugin: The new `unixsock' plugin provides an interface to
707 communicate with the daemon while it is running. Right now the
708 commands `GETVAL' and `PUTVAL' are implemented, but more are to
710 * perl plugin: The new `perl' plugin allows you to write extensions
711 for collectd in the scripting-language Perl.
712 * logfile plugin: The new `logfile' plugin writes logmessages to files
714 * syslog plugin: The new `syslog' plugin sends logmessages to the
715 system's syslog daemon.
716 * entropy plugin: The new `entropy' plugin collects the amount of
717 entropy currently being available to the system.
718 * exec plugin: The new `exec' plugin forks child processes and reads
719 back values provided by the forked processes.
720 * iptables plugin: The new `iptables' plugin reads counters from
721 iptables rules. Thanks to Sjoerd van der Berg for contributing this
723 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
724 to Peter Holik for contributing this plugin.
725 * nut plugin: The new `nut' plugin connects the upsd of the `network
726 ups tools' and reads information about the connected UPS.
727 * apache plugin: Support for lighttpd's `BusyServers' (aka.
728 connections) field was added by Florent Monbillard.
729 * collectd-nagios: The new `collectd-nagios' binary queries values
730 from collectd, parses them and exits according to Nagios-standards.
731 * manpages: The manpages have been improved a lot.
733 2007-09-28, Version 3.11.7
734 * wireless plugin: Correct the handling of cards returning signal and
735 noise quality as percentage.
737 2007-08-31, Version 3.11.6

741 * configure: Added `AC_SYS_LARGEFILE' for LFS.
742 * ntpd plugin: Fix a potential buffer overflow.
743 * processes plugin: Fix a bug when run under Linux 2.4. All processes
744 were accounted as `zombies'.
746 2007-04-10, Version 3.11.4
747 * dns plugin: Change the order of includes to make the plugin compile
750 2007-03-30, Version 3.11.3
751 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
752 of the unused `COLLECT_KSTAT'.
754 2007-02-11, Version 3.11.2
755 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
756 NULL-pointer may have been passed to `printf' which causes a
757 segfault with some libcs.
759 2007-02-10, Version 3.11.1
760 * df plugin: Some wrong defines have been fixed so the plugin works
762 * dns plugin: The usage of a struct has been fixed to work with
764 * processes plugin: Some missing defines have been added so the plugin
765 compiles cleanly under FreeBSD and presumably other UNIXes.
767 2006-12-22, Version 3.11.0
768 * collectd: The new command line option `-P' makes it easier for
769 distributors to change the location of PID-files.
770 * collectd: The daemon shuts down faster now which makes it easier to
771 write init.d-scripts for it.
772 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
773 caused problems every now and then.
774 * df plugin: New config options allow to ignore certain mountpoints,
775 filesystem types or devices.
776 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
777 and interprets it. It collects traffic as well as qtype, opcode and
779 * email plugin: Sebastian Harl has contributed this plugin which
780 counts received mails in categories (e. g. ham, spam, virus), spam
781 score (as given by SpamAssassin) and check types.
782 * mbmon plugin: Flavio Stanchina has contributed this plugin which
783 uses `mbmon' to gather information from sensors on the motherboard.
784 * processes plugin: Collect detailed statistics for configured
785 processes, that's process and thread count, CPU usage, resident
786 segment size and pagefaults.
787 * multimeter plugin: Peter Holik contributed a new plugin which
789 * sensors plugin: Lubos Stanek has put much effort into improving this
790 plugin, including `extended naming', collection of voltage values
791 and the possibility to ignore certain values.
793 2006-12-21, Version 3.10.4
794 * Max Kellermann has identified a bug in the server routine: When
795 opening a socket fails the daemon will (re)try opening the socket in
796 an endless loop, ultimately leading to a `EMFILE' error.
798 2006-11-04, Version 3.10.3
799 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
800 ntpd's reply was sent in more than one packet, the buffer size was
801 calculated incorrectly, resulting in the reading of uninitialized or
804 2006-11-01, Version 3.10.2
805 * The sample config file has been improved.
806 * Errors in the manpages have been corrected.
807 * The ping-plugin now adds hosts during initialization, not during
808 startup. This speeds up startup when no network connectivity is
809 available. Also, the hosts are being added later when the network is
811 * Improved BSD-support for the df-plugin.
812 * Fixed syntax errors in the swap-plugin for Mac OS X.
813 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
815 * Don't disable the mysql-plugin if connecting to the database fails
816 during initialization. Instead, try again in increasing intervals.
818 2006-07-19, Version 3.10.1
819 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
820 the apcups cannot be reached, unconnected sockets will pile up and
821 eventually lead to `Too many open files' errors.
823 2006-07-09, Version 3.10.0
824 * The `disk' plugin has been ported to Darwin.
825 * The `battery' plugin should work on many Apple computers now.
826 * The `traffic' plugin can now ignore certain interfaces. Also,
827 statistics for sent/received packets and errors have been added.
828 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
829 to Anthony Gialluca for contributing this plugin and providing me
830 with a test environment :)
831 * A plugin for monitoring an NTP instance and the local clock drift
834 2006-06-25, Version 3.9.4
835 * The Solaris code in the `swap' plugin has been changed to reflect
836 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
838 * The debugging system has been fixed to work with the Sun libc.
839 * When built without librrd the variable `operating_mode' could be
840 uninitialized. Thanks to David Elliot for reporting the bug.
842 2006-06-01, Version 3.9.3
843 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
844 operating systems also profit from the changes, but I wasn't able to
846 * Changed the build system to find the netinet-includes under FreeBSD
847 and therefore successfully build the `liboping' library there.
849 2006-05-09, Version 3.9.2
850 * Applied a patch to the `liboping' library. Due to a bug in the
851 sequence checking the `ping' plugin stopped working after
852 approximately 7.6 days.
854 2006-05-09, Version 3.8.5
855 * Applied a patch to the `liboping' library. Due to a bug in the
856 sequence checking the `ping' plugin stopped working after
857 approximately 7.6 days.
859 2006-04-21, Version 3.9.1
860 * Build issues with Solaris and possible other architectures have been
862 * Problems when building the `apache'-plugin without `libcurl' have
864 * A bug in the `ping' plugin has been fixed. Sorry folks.
866 2006-04-02, Version 3.9.0
867 * A plugin to monitor the Apache webserver has been added.
868 <http://httpd.apache.org/>
869 * A plugin to collect statistics about virtual servers using VServer.
870 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
872 * A plugin for wireless LAN cards has been added. It monitors signal
873 strength, link quality and noise ratio..
874 * A plugin for Apple hardware sensors has been added.
875 * An option to compile collectd with different `step' and `heartbeat'
876 settings has been added. The size of RRAs is no longer static but
877 calculated based on the settings for `step' and `width'.
878 * The `ping' plugin can now be configured to use a certain TTL.
879 * A plugin to monitor the hardware sensors of Apple computers has been
881 * The plugins `cpu', `memory', `processes' and `traffic' have been
882 ported to Mach/Darwin (Mac OS X).
883 * The `log mode' has been contributed by Christophe Kalt. It writes
884 the data into text files rather than RRD files.
886 2006-04-09, Version 3.8.4
887 * Applied patch by Vincent Stehlé which improves the disk-name
888 resolution in the `hddtemp' plugin for Linux systems.
890 2006-04-02, Version 3.8.3
891 * Applied a patch by James Byers: The MySQL plugin was not working
892 with MySQL 5.0.2 or later.
894 2006-03-14, Version 3.8.2
895 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
896 the GNU libc, because it points to `/etc/fstab' rather than
899 2006-03-13, Version 3.8.1
900 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
901 * Fixes in the debian `postinst' and `init.d' scripts.
903 2006-03-09, Version 3.8.0
904 * The `ping' plugin no longer uses `libping' but a self written
905 library named `liboping'. With this library it's possible to ping
906 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
908 2006-02-18, Version 3.7.2
909 * A simple bug in the `battery' plugin has been fixed. It should now
910 work with ACPI based batteries as well. Thanks to Sebastian for
912 * Fixing a bug that prevented collectd to be built without librrd.
913 Thanks to Werner Heuser for reporting it.
915 2006-02-04, Version 3.7.1
916 * The new network code has been improved to build with older versions
918 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
919 to Tommie Gannert for this patch.
921 2006-01-30, Version 3.7.0
922 * The `battery' plugin has been added. It collects information about
924 * The MySQL plugin has been improved: It now writes two more RRD
925 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
926 * The `cpufreq' plugin now reads another file since the file it did
927 read so far causes much overhead in the kernel. Also, you need root
928 to read the old file, but not to read the new one.
929 * The `hddtemp' plugin can now be configured to connect to another
930 address and/or port than localhost.
931 * The `df' plugin now prefers `statvfs' over `statfs'.
932 * The network code has been rewritten. collectd now supports unicast
933 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
934 be set in the configfile.
936 2006-01-24, Version 3.6.2
937 * Due to a bug in the configfile handling collectd wouldn't start in
938 client mode. This released fixes this.
940 2006-01-20, Version 3.6.1
941 * Due to a bug in `configure.in' all modules and the binary were
942 linked against `libmysqlclient'. This issue is solved by this
945 2006-01-17, Version 3.6.0
946 * A config file has been added. This allows for loading only specific
948 * A `df' plugin has been added.
949 * A `mysql' plugin has been added.
950 * The `ping' plugin doesn't entirely give up hope when a socket error
951 occurred, but will back of and increase the intervals between tries.
953 2006-01-21, Version 3.5.2
954 * Fixed yet another bug in the signal handling.. Stupid typo..
955 * Improved the ping plugin to not give up on socket errors (backport
958 2005-12-18, Version 3.5.1
959 * The PID-file is now deleted correctly when shutting down the daemon.
960 * SIGINT and SIGTERM are now handled correctly.
962 2005-12-16, Version 3.5.0 (Revision 326)
963 * A bug in the `load' module under Solaris has been fixed.
964 * The `users' module has been contributed by Sebastian Harl. It counts
965 currently logged in users.
966 * The CPU module now works under FreeBSD without the use of
967 `libstatgrab', however SMP support is missing.
968 * The default directories for the RRD files and the PID file now
969 depend on the compile time setting of `localstatedir'.
971 2005-11-15, Version 3.4.0 (Revision 236)
972 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
973 from gentoo's bugzilla for writing the patch.
974 * The build dependency for librrd has been removed. Binaries built
975 without librrd are client-only and will multicast their value as
976 with the `-c' argument.
977 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
978 * The newly introduced `-f' switch prevents daemon initialization
979 (forking, closing standard filehandles, etc.) Thanks to Alvaro
980 Barcellos for this patch.
982 2005-11-04, Version 3.3.0 (Revision 216)
983 * New modules have been added:
984 - `serial', for monitoring traffic on the serial interfaces
985 - `nfs', for graphing NFS procedure calls
986 - `tape', traffic from/to tape devices

995 * Problems with the spec file have been fixed.
997 2005-10-16, Version 3.1.0 (Revision 194)
998 * Added the `setsid' syscall to the startup code.
999 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1001 2005-09-30, Version 3.0.0 (Revision 184)
1002 * The ability to send/receive data to/from the network (think
1003 multicast) has been added.
1004 * Modules have been split up into shared libraries can be loaded at
1005 runtime. The biggest advantage is that the core program doesn't need
1006 to be linked against an external library.
1007 * A patch by George Kargiotakis has been applied: It fixes the sensors
1008 behaviour then more than one sensor is being queried.
1010 2005-09-16, Version 2.1.0 (Revision 172)
1011 * A module for swap statistics has been added.
1013 2005-09-09, Version 2.0.0 (Revision 135)
1014 * Filenames can no longer be configured at program startup. The only
1015 options as of this version are the directory and ping hosts.
1016 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1017 Soft-IRQ statistics are added to `System'.
1018 * Diskstats now collect read and write bytes, not sectors.
1019 * Ping statistics can now be collected for more than one host. There
1020 is no default any more: If no host is given no host will be pinged.
1021 * A self-written patch for libping has been applied so it builds
1024 2005-09-01, Version 1.8.1 (Revision 123)
1025 * Much improved configure-script: libraries and features may now be
1027 * More detailed warnings/error messages when RRD update fails.
1029 2005-08-29, Version 1.8.0:
1030 * Support for collecting disk statistics under Solaris.
1032 2005-08-25, Version 1.7.0:
1033 * Support for libstatgrab[1] for load, memory usage and network
1034 traffic. CPU- and disk-usage are not (yet) supported, since
1035 libstatgrab returns insufficient information. I will contact the
1037 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1038 aren't necessarily counted linear which is now handled correctly.

1041 2005-08-21, Version 1.6.0:
1042 * Basic support for Solaris: System load and cpu-usage can be
1043 collected under Solaris, too. Other stats will follow later.
1044 * Many fixes in the autoconf-script
1045 * Collection/Museum scripts have been added under contrib/museum
1046 * collectd may now be started in unprivileged mode, though ping
1047 statistics will not work.
1049 2005-07-17, Version 1.5.1:
1050 * Diskstats-RRDs now use major/minor for naming. Some systems have
1051 weird strings as disk-names..
1053 2005-07-17, Version 1.5:
1054 * A new module, diskstats, has been added. It collects information
1055 about the disks and partitions.
1057 2005-07-11, Version 1.4.2:
1058 * The meminfo module has been changed to work with more platforms
1059 and/or kernel versions.
1061 2005-07-10, Version 1.4.1: Correct traffic stats
1062 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1063 forgot to correct when I changed that module.
1065 2005-07-09, Version 1.4: More traffic stats
1066 * Traffic is now collected for all interfaces that can be found
1067 * Temperature-statistics are read from lm-sensors if available
1069 2005-07-08, Version 1.3: CPU stats
1070 * Collecting CPU statistics now
1072 2004-07-12, Version 1.2: Using syslog
1073 * collectd is now using the syslog facility to report errors, warnings
1075 * The default directory is now /var/db/collectd
1077 2004-07-10, Version 1.1: Minor changes
1078 * Nothing really useful to say ;)
1080 2004-07-09, Version 1.0: Initial Version
