1 2009-05-09, Version 4.5.4
2 * Build system, various plugins: Many build fixes for FreeBSD,
3 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
4 for many fixes and providing a build system for many platforms,
5 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
6 providing an OpenBSD system.
7 * collectd: Fix a potential race condition when creating directories.
8 * battery plugin: Don't complain about a missing directory every
10 * dns plugin: Slight portability fixes.
11 * exec plugin: Allow executed programs to close STDERR. Thanks to
12 Thorsten von Eicken for reporting this problem.
13 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
14 Tomasz Pala for the patch.
15 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
17 * rrdtool plugin: Fix a possible race condition: If the network plugin
18 is initialized and dispatches a value before the rrdtool plugin is
19 initialized, the daemon may crash.
20 * memory plugin: Fix a potential problem under Solaris.
22 2009-02-22, Version 4.5.3
23 * build system: The check for libupsclient even when `pkg-config' is
25 * collectd: Fix error handling in the global cache.
26 * Collectd::Unixsock: Error handling has been improved.
27 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
29 * ipmi plugin: Fix an off-by-one error which could cause segmentation
30 faults. Thanks to Peter Holik for his patch.
31 * tcpconns plugin: An endianness problem has been fixed in the *BSD
32 code. Thanks to "thated" for reporting this.
34 2009-01-02, Version 4.5.2
35 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
36 file may be in both locations, especially when the database was
37 installed in a non-standard path. Thanks to Dusty Doris for
39 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
40 Solaris, in the configure script automatically.
41 * build system, tcpconns plugin: Check for `kvm_nlist' and
42 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
43 library with similar functions to the BSD variant, but doesn't
44 provide these necessary functions.
45 * collectd.conf(5): Various fixes and clarifications.
46 * collectd: Remove a GNUism (unnamed unions), thus improving
48 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
49 This solves portability problems, especially for Solaris.
50 * dns plugin: Fix a portability problem with NetBSD.
51 * filecount plugin: Fix an off-by-one error. This error may cause a
53 * network plugin: Fix the handling of `type' in the network protocol.
54 Due to a programming mistake, only 4 or 8 bytes would be copied to a
55 much larger buffer. This caused the `type' to be transferred much
56 more often than necessary. In some cases, e. g. the `cpu' and
57 `cpufreq' plugins being used at the same time, data may be corrupted
58 in those files. Thanks to Bruno Prémont for debugging and reporting
60 * processes plugin: Fix a possible segmentation fault when specifying
61 invalid configuration options.
62 * unixsock plugin: Make sure the initialization function is run only
63 once. This resolves a file descriptor leak under systems which run
64 the initialization more than once, such as Solaris.
66 2008-10-16, Version 4.5.1
67 * build system: Change `--enable-<plugin>' to abort with an error if
68 dependencies are not met. Thanks to Bruno Prémont for the patch.
69 Also, the poisoning of various string functions has been restricted
71 * collectd: Fix a memory leak in the global value cache. With every
72 *missing* value a couple of bytes would be leaked. Another memory
73 leak in the configuration handling code has been fixed. Thanks to
74 Niraj Tolia for reporting these issues.
75 * collectd: Fix an off-by-one error in the ignorelist functionality.
76 When using regular expressions, the last character would be missing,
77 possibly matching differently from what one would expect.
78 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
80 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
81 Linzberger for reporting the bug.
82 * iptables plugin: Fix an off-by-one error. If a string was just one
83 character too long, it was truncated instead of reporting an error.
84 * network plugin: Fix a memory leak in the configuration handling
85 code. Thanks to Niraj Tolia for reporting this issue.
86 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
87 * postgresql plugin: Don't reopen connection during reinitialization.
88 This fixes a bug under Solaris and potentially other platforms.
89 Missing calls to `PQclear' have been added, too. This fixes memory
90 leaks. Thanks to ``Admin'' for reporting these bugs.
91 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
93 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
94 problems with some `libc's. Thanks to Matthias Lay for reporting the
97 2008-09-04, Version 4.5.0
98 * collectd: Added the ability to flush certain identifiers.
99 * collectd: The concept of `notification meta data' has been
101 * filecount plugin: The new filecount plugin counts the number of
102 files in a directory and its subdirectories.
103 * ipmi plugin: Sensor names have been changed to ensure unique names.
104 Notifications upon added and removed sensors can now be generated.
105 * notify_desktop plugin: This new plugin sends notifications to the
106 X desktop using the structure defined in the `Desktop Notification
108 * notify_email plugin: This new plugin sends out notifications via
109 email, using the `esmtp' library.
110 * onewire plugin: The new experimental(!) onewire plugin reads values,
111 such as temperatures, from sensors connected to the computer via the
113 * perl plugin: Improved synchronized access to internal data structures
114 and fixed a possible dead-lock.
115 * perl plugin: Added the ability to flush certain identifiers and marked
116 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
118 * perl plugin: Added the ability to configure Perl plugins.
119 * postgresql plugin: The new postgresql plugin collects statistics
120 about or from a PostgreSQL database.
121 * processes plugin: The `ProcessMatch' option has been added.
122 * rrdtool plugin: Implement throttling of the `update queue' to lessen
124 * tcpconns plugin: This plugin has been ported to OpenBSD.
125 * thermal plugin: The new thermal plugin collects system temperatures
126 using Linux ACPI thermal zone data.
128 2009-01-02, Version 4.4.5
129 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
130 file may be in both locations, especially when the database was
131 installed in a non-standard path. Thanks to Dusty Doris for
133 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
134 Solaris, in the configure script automatically.
135 * collectd.conf(5): Various fixes and clarifications.
136 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
137 portability problems, especially for Solaris.
138 * dns plugin: Fix a portability problem with NetBSD.
139 * network plugin: Fix the handling of `type' in the network protocol.
140 Due to a programming mistake, only 4 or 8 bytes would be copied to a
141 much larger buffer. This caused the `type' to be transferred much
142 more often than necessary. In some cases, e. g. the `cpu' and
143 `cpufreq' plugins being used at the same time, data may be corrupted
144 in those files. Thanks to Bruno Prémont for debugging and reporting
146 * unixsock plugin: Make sure the initialization function is run only
147 once. This resolves a file descriptor leak under systems which run
148 the initialization more than once, such as Solaris.
150 2008-10-16, Version 4.4.4
151 * build system: Change `--enable-<plugin>' to abort with an error if
152 dependencies are not met. Thanks to Bruno Prémont for the patch.
153 Also, the poisoning of various string functions has been restricted
155 * collectd: Fix a memory leak in the global value cache. With every

165 Linzberger for reporting the bug.
166 * network plugin: Fix a memory leak in the configuration handling
167 code. Thanks to Niraj Tolia for reporting this issue.
168 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
169 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
170 problems with some `libc's. Thanks to Matthias Lay for reporting the
173 2008-09-01, Version 4.4.3
174 * collectd: Fix a memory leak in the threshold checking code.
175 * memcached plugin: Fix a too short timeout and a related file

186 * dns plugin: Fix compilation errors with BIND versions 19991001
188 * network plugin: Bugfix in the init routine: The init function
189 cleared a buffer regardless of its contents. This could lead to lost
190 values under Solaris.
191 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
192 * vserver plugin: Remove usage of the thread-unsafe `readdir'
194 * wireless plugin: Work around incorrect noise and power values
195 returned by some broken drivers.

198 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
199 to kyrone for reporting this.
200 * collectd: Fixed min/max output in notifications generated by
202 * collectd-nagios: Fix the protocol used to communicate with the
204 * perl plugin: Fail noisily, but don't shutdown the daemon, if
205 initialization has errors. An issue with Perl 5.10 has been fixed.
206 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
207 René Rebe and Siegmund Gorr for reporting this.
209 2008-05-06, Version 4.4.0
210 * collectd: Internal code cleanups.
211 * collectd: Added support for a `Flush' command in the unixsock and
212 exec plugins. This command can be used to force a plugin (or all) to
213 flush its values to disk.
214 * collectd: Thresholds can now be configured to apply to one data
215 source only, making it possible to configure different thresholds
216 for each data source.
217 * apache, nginx plugins: Added the possibility to disable host and/or
219 * ascent plugin: The new ascent plugin reads and parses the statistics
220 page of an Ascent server.
221 * cpu plugin: Support for the statgrab library has been added.
222 * disk plugin: The possibility to ignore certain disks or collect only
223 specific disks has been added.
224 * disk plugin: Support for the statgrab library has been added.
225 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
226 sensor values via IPMI, the intelligent platform management
228 * iptables plugin: The iptc library that is used by the iptables
229 plugin has been added to the distribution, because it is not
230 provided by all distributions and removed from at least one.
231 * powerdns plugin: The new powerdns plugin reads statistics from an
232 authoritative or a recursing PowerDNS name server.
233 * rrdtool plugin: The size of the files generated with the default
234 configuration has been decreased.
235 * tail plugin: The new tail plugin can be used to gather statistics by
236 continuously reading from log files.
237 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
238 TeamSpeak2 server and collects statistics about the number of users
239 and number of channels.
240 * users plugin: Support for the statgrab library has been added.
241 * vmem plugin: The new vmem plugin collects very detailed statistics
242 about the virtual memory subsystem of Linux.

263 * build system: Improved detection of several libraries, especially if
264 they are in non-standard paths.
265 * build system: Portability fixes: Automatically define "_REENTRANT"
266 if the libc expects it.
267 * collectd: Error and warning messages have been improved.
268 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
270 * apache plugin: Allocate new memory when reading a webpage instead of
271 using a buffer of static size.
272 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
274 * hddtemp plugin: Error and warning messages have been improved.
275 * sensors plugin: Fix sensor collection for some chip types.
277 2008-03-29, Version 4.3.2
278 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
279 `Persist' threshold options.
280 * collectd: Fix handling of missing values in the global value cache.

286 2008-03-05, Version 4.3.1
287 * exec plugin: Set supplementary group IDs.
289 + Use `memcpy' when constructing/parsing a package to avoid
290 alignment problems on weird architectures, such as Sparc.
291 + Translate doubles to/from the x86 byte representation to ensure
292 cross-platform compatibility.
293 * ping plugin: Correct the handling of the `TTL' setting.
294 * swap plugin: Reapply a patch for Solaris.
295 * tcpconns plugin: Portability improvements.
297 2008-02-18, Version 4.3.0
298 * collectd: Notifications have been added to the daemon. Notifications
299 are status messages that may be associated with a data instance.
300 * collectd: Threshold checking has been added to the daemon. This
301 means that you can configure threshold values for each data
302 instance. If this threshold is exceeded a notification will be
304 * collectd: The new `FQDNLookup' option tells the daemon to use the
305 full qualified domain name as the hostname, not just the host part
306 es returned by `gethostname(2)'.
307 * collectd: Support for more than one `TypesDB' file has been added.
308 This is useful when one such file is included in a package but one
309 wants to add custom type definitions.
310 * collectd: The `Include' config option has been expanded to handle
311 entire directories and shell wildcards.
312 * collectdmon: The new `collectdmon' binary detects when collectd

314 * csv plugin: The CSV plugin is now able to store counter values as a
315 rate, using the `StoreRates' configuration option.
316 * exec plugin: Handling of notifications has been added and the
317 ability to pass arguments to the executed programs has been added.
318 * hddtemp plugin: The new `TranslateDevicename' option lets you
319 disable the translation from device names to major-minor-numbers.
320 * logfile plugin: Handling of notifications has been added.
321 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
322 domain name lookups in this plugin.
323 * perl plugin: Many internal changes added support for handling multiple
324 threads making the plugin reasonably usable inside collectd. The API has
325 been extended to support notifications and export global variables to
326 Perl plugins; callbacks now have to be identified by name rather than a
327 pointer to a subroutine. The plugin is no longer experimental.
328 * uuid plugin: The new UUID plugin sets the hostname to an unique
329 identifier for this host. This is meant for setups where each client
330 may migrate to another physical host, possibly going through one or
331 more name changes in the process. Thanks to Richard Jones from
332 Red Hat's Emerging Technology group for this plugin.
333 * libvirt: The new libvirt plugin uses the `libvirt' library to query
334 CPU, disk and network statistics about guest systems on the same
335 physical server. Thanks to Richard Jones from Red Hat's Emerging
336 Technology group for this plugin.
338 2008-04-22, Version 4.2.7
339 * build system: Improved detection of several libraries, especially if
340 they are in non-standard paths.
341 * build system: Portability fixes: Automatically define "_REENTRANT"
342 if the libc expects it.
343 * collectd: Error and warning messages have been improved.
344 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
346 * apache plugin: Allocate new memory when reading a webpage instead of
347 using a buffer of static size.
348 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
350 * hddtemp plugin: Error and warning messages have been improved.

359 2008-03-04, Version 4.2.5
360 * apache plugin: Improved initialization and error messages.
361 * exec plugin: Set supplementary group IDs.
363 + Create separate threads for reading from the socket and parsing
364 and dispatching incoming packets. Versions prior to this may have
365 problems in high-load situations, where the socket receive buffers
366 overflows, resulting in gaps in the data.
367 + Use `memcpy' when constructing/parsing a package to avoid
368 alignment problems on weird architectures, such as Sparc.
369 + Translate doubles to/from the x86 byte representation to ensure
370 cross-platform compatibility.
371 * ping plugin: Correct the handling of the `TTL' setting.
372 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
373 * swap plugin: Reapply a patch for Solaris.
374 * tcpconns plugin: Portability improvements.
376 2008-01-21, Version 4.2.4
377 * unixsock plugin: A bug in the unixsock plugin caused it not to set
378 the permission on the socket as documented in the manpage. Thanks to
379 Evgeny Chukreev for fixing this issue.
380 * collectd: The documentation has been improved.
382 2007-12-28, Version 4.2.3
383 * sensors plugin: Updated the plugin to build and work with version 3
384 of the libsensors library.
386 2007-12-15, Version 4.2.2
387 * nginx plugin: Incorrect comparison of strings lead to a segfault
388 when using the plugin. Thanks to Saulius Grigaliunas for fixing
390 * logfile plugin: The config option `Timestamp' was handled
391 incorrectly and basically always active. Thanks to Luke Heberling
394 2007-11-08, Version 4.2.1
395 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
397 * snmp plugin: Fix a memory leak.
399 2007-10-27, Version 4.2.0
400 * collectd: The new config option `Include' lets you include other
401 configfiles and thus split up your config into smaller parts. This
402 may be especially interesting for the snmp plugin to keep the data
403 definitions separate from the host definitions.
404 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
405 (number of connections, octets and packets for each service and
406 destination). Thanks to Sebastian Harl for this plugin.
407 * memcached plugin: The new `memcached' plugin connects to a memcached
408 daemon process and collects statistics of this distributed caching
409 system. Thanks to Antony Dovgal for contributing this plugin.
410 * nginx plugin: The new `nginx' plugin reads the status page of an
411 nginx daemon and saves the handled connections and requests.
412 * perl plugin: Many changes, including the added `EnableDebugger'
413 config option which lets you debug your Perl plugins more easily.
414 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
415 be more thread-safe otherwise by locking calls to the library.
416 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
417 correct the values returned by SNMP-agents. If a <data> block is
418 defined as `table' the instance is now optional. The sequence number
419 is used as the type-instance in this case. The new `InstancePrefix'
420 option allows to add arbitrary prefixes to the type-instance.
421 * tcpconns plugin: The new `tcpconns' plugin collects the number of
422 certain TCP connections and what state they're in. This can be used
423 to see how many connections your FTP server has to handle or how
424 many outgoing connections your mailserver has open.
426 2008-01-11, Version 4.1.6
427 * unixsock plugin: A bug in the unixsock plugin caused it not to set
428 the permission on the socket as documented in the manpage. Thanks to
429 Evgeny Chukreev for fixing this issue.
430 * collectd: The documentation has been improved.
432 2007-12-27, Version 4.1.5

436 of the libsensors library.
438 2007-11-08, Version 4.1.4
439 * Build system: Improve detection of the rrd library, especially if
440 it's in a non-standard location.
441 * Build system: A bug when parsing the argument for
442 `--with-libnetsnmp' has been fixed.
443 * collectd: Implement `strerror_r' if the libc doesn't provide it.
444 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
445 a deadlock or delay when shutting down the daemon.
446 * snmp plugin: Fix a memory leak.
448 2007-10-24, Version 4.1.3
449 * collectd: A build issue under Solaris has been resolved by renaming
451 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
452 be more thread-safe otherwise by locking calls to the library.
454 2007-09-28, Version 4.1.2
455 * apcups plugin: Fix reporting of the `load percent' data.
456 * wireless plugin: Correct the handling of cards returning signal and
457 noise quality as percentage.
458 * perl plugin: Fix a possible buffer overflow in get_module_name().
459 * build system: Further improve the detection of libraries.
460 * netlink plugin: Build issues under some older versions of the Linux
461 includes (i. e. Debian Sarge) have been fixed.

463 support for the `timeticks' type.
465 2007-09-12, Version 4.1.1
466 * Build system: The detection of `libnetlink' has been improved.
467 * collectd: The documentation has been fixed in numerous places.
468 * exec plugin: Setting the group under which to run a program has been
470 * collectd: The `sstrerror' function was improved to work correctly
471 with the broken GNU version of `strerror_r'.
472 * collectd: Write an error message to STDERR when loading of a plugin
474 * apcups plugin: Fix the `types' used to submit the values: They still
475 has an `apcups_' prefix which doesn't work anymore.
476 * rrdtool plugin: Create new RRD-files with the `begin' time set to
477 whatever the client thinks is `now'..
479 2007-09-01, Version 4.1.0
480 * Build system: The build system has been changed to automatically
481 disable all plugins, which are missing dependencies. The dependency
482 checking has been removed from the plugins themselves to remove
484 * Flexible interval: The interval of collected data is now sent along
485 with the data itself over the network, so that the interval-settings
486 of server and clients no longer needs to match.
487 * netlink plugin: The new `netlink' plugin connects to the Linux
488 kernel using a netlink socket and uses it to query information about
489 interfaces, qdiscs and classes.
490 * rrdtool plugin: The cache is now dumped to disk in an extra thread
491 to not block data collection.
492 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
493 network devices, such as switches, routers, thermometers, rack
494 monitoring servers, etc. The collectd-snmp(5) manpage documents this
496 * unixsock plugin: Added the `LISTVAL' command.
497 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
498 of music played with xmms.
500 2007-09-28, Version 4.0.9
501 * apcups plugin: Fix reporting of the `load percent' data.
502 * wireless plugin: Correct the handling of cards returning signal and

507 * collectd: The `sstrerror' function was improved to work correctly
508 with the broken GNU version of `strerror_r'.
509 * collectd: Write an error message to STDERR when loading of a plugin
511 * apcups plugin: Fix the `types' used to submit the values: They still
512 has an `apcups_' prefix which doesn't work anymore.
513 * rrdtool plugin: Create new RRD-files with the `begin' time set to
514 whatever the client thinks is `now'..
516 2007-08-26, Version 4.0.7
517 * documentation: Some typos have been fixed and some information has
519 * build system: Many fixes for detecting libraries in unusual places,
520 such as on RedHat systems. The affected libraries are `libcurl',
521 `libmysql', and `libupsclient'.
522 * network plugin: Allow the `Port' option to be specified as a number
523 (i. e. without quotes).
524 * nut plugin: A fix allows linking the nut plugin against
525 libupsclient, version >= 2.2.0.
526 * processes plugin: Fix a potential segmentation fault.
528 2007-07-30, Version 4.0.6
529 * sensors plugin: Fix the ignorelist functionality: Only the `type
530 instance' was used to match against the list, but the documentation
531 told otherwise. This release fixes the code, so it complies with the
533 * syslog plugin: Call `openlog' right when the plugin is loaded, so
534 configuration messages will end up in the logging facility.
535 * conrtib/fedora: The contributed specfile for Fedora has been
538 2007-07-05, Version 4.0.5
539 * Portability: More fixes for OpenBSD have been included.
541 2007-06-24, Version 4.0.4
542 * cpu plugin: Fixed the Solaris code.
543 * dns plugin: Fixed a build issue for OpenBSD.
544 * interface plugin: Fixed the Solaris code.
545 * load plugin: Fixed the alternative `/proc' Linux code.

558 they're given in numerically form.
560 2007-06-07, Version 4.0.1
561 * iptables plugin: A bug in the configuration routine has been fixed.
562 Setting a comment in the configfile will no longer cause a
565 2007-06-03, Version 4.0.0
566 * collectd: The plugin-infrastructure has been changed to allow for
567 more types of plugins, namely `write' and `log' plugins.
568 * collectd: The read-function has been changed to read many plugins in
569 parallel, using threads. Thus, plugins generally need to use
570 thread-safe functions from now on.
571 * collectd: The '-t' command line options allows to perform syntax tests
572 of the configuration file and exit immediately.
573 * csv plugin: The new `csv' plugin handles output to `comma separated
575 * rrdtool plugin: The new `rrdtool' plugin handles output to
576 RRD-files. Data can be cached to combine multiple updates into one
577 write to increase IO-performance.
578 * network plugin: The new `network' plugin handles IO via the network.
579 It implements a different, much more extensible protocol which can
580 combine many values in one packet, decreasing the number of UDP-
581 packets being sent. It can read from and send to the network and
582 with the appropriate configuration even forward packets to other
584 * unixsock plugin: The new `unixsock' plugin provides an interface to
585 communicate with the daemon while it is running. Right now the
586 commands `GETVAL' and `PUTVAL' are implemented, but more are to
588 * perl plugin: The new `perl' plugin allows you to write extensions
589 for collectd in the scripting-language Perl.
590 * logfile plugin: The new `logfile' plugin writes logmessages to files
592 * syslog plugin: The new `syslog' plugin sends logmessages to the
593 system's syslog daemon.
594 * entropy plugin: The new `entropy' plugin collects the amount of
595 entropy currently being available to the system.
596 * exec plugin: The new `exec' plugin forks child processes and reads
597 back values provided by the forked processes.
598 * iptables plugin: The new `iptables' plugin reads counters from
599 iptables rules. Thanks to Sjoerd van der Berg for contributing this
601 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
602 to Peter Holik for contributing this plugin.
603 * nut plugin: The new `nut' plugin connects the upsd of the `network
604 ups tools' and reads information about the connected UPS.
605 * apache plugin: Support for lighttpd's `BusyServers' (aka.
606 connections) field was added by Florent Monbillard.
607 * collectd-nagios: The new `collectd-nagios' binary queries values
608 from collectd, parses them and exits according to Nagios-standards.
609 * manpages: The manpages have been improved a lot.
611 2007-09-28, Version 3.11.7
612 * wireless plugin: Correct the handling of cards returning signal and
613 noise quality as percentage.
615 2007-08-31, Version 3.11.6
616 * processes plugin: Fix a potential segmentation fault.
618 2007-05-29, Version 3.11.5
619 * configure: Added `AC_SYS_LARGEFILE' for LFS.
620 * ntpd plugin: Fix a potential buffer overflow.
621 * processes plugin: Fix a bug when run under Linux 2.4. All processes
622 were accounted as `zombies'.
624 2007-04-10, Version 3.11.4
625 * dns plugin: Change the order of includes to make the plugin compile
628 2007-03-30, Version 3.11.3
629 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
630 of the unused `COLLECT_KSTAT'.
632 2007-02-11, Version 3.11.2
633 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
634 NULL-pointer may have been passed to `printf' which causes a
635 segfault with some libcs.
637 2007-02-10, Version 3.11.1
638 * df plugin: Some wrong defines have been fixed so the plugin works
640 * dns plugin: The usage of a struct has been fixed to work with
642 * processes plugin: Some missing defines have been added so the plugin
643 compiles cleanly under FreeBSD and presumably other UNIXes.
645 2006-12-22, Version 3.11.0
646 * collectd: The new command line option `-P' makes it easier for
647 distributors to change the location of PID-files.
648 * collectd: The daemon shuts down faster now which makes it easier to
649 write init.d-scripts for it.
650 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
651 caused problems every now and then.
652 * df plugin: New config options allow to ignore certain mountpoints,
653 filesystem types or devices.
654 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
655 and interprets it. It collects traffic as well as qtype, opcode and
657 * email plugin: Sebastian Harl has contributed this plugin which
658 counts received mails in categories (e. g. ham, spam, virus), spam
659 score (as given by SpamAssassin) and check types.
660 * mbmon plugin: Flavio Stanchina has contributed this plugin which
661 uses `mbmon' to gather information from sensors on the motherboard.
662 * processes plugin: Collect detailed statistics for configured
663 processes, that's process and thread count, CPU usage, resident
664 segment size and pagefaults.
665 * multimeter plugin: Peter Holik contributed a new plugin which
667 * sensors plugin: Lubos Stanek has put much effort into improving this
668 plugin, including `extended naming', collection of voltage values
669 and the possibility to ignore certain values.
671 2006-12-21, Version 3.10.4
672 * Max Kellermann has identified a bug in the server routine: When
673 opening a socket fails the daemon will (re)try opening the socket in
674 an endless loop, ultimately leading to a `EMFILE' error.
676 2006-11-04, Version 3.10.3
677 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
678 ntpd's reply was sent in more than one packet, the buffer size was
679 calculated incorrectly, resulting in the reading of uninitialized or
682 2006-11-01, Version 3.10.2
683 * The sample config file has been improved.
684 * Errors in the manpages have been corrected.
685 * The ping-plugin now adds hosts during initialization, not during
686 startup. This speeds up startup when no network connectivity is
687 available. Also, the hosts are being added later when the network is
689 * Improved BSD-support for the df-plugin.
690 * Fixed syntax errors in the swap-plugin for Mac OS X.
691 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
693 * Don't disable the mysql-plugin if connecting to the database fails
694 during initialization. Instead, try again in increasing intervals.
696 2006-07-19, Version 3.10.1
697 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
698 the apcups cannot be reached, unconnected sockets will pile up and
699 eventually lead to `Too many open files' errors.
701 2006-07-09, Version 3.10.0
702 * The `disk' plugin has been ported to Darwin.
703 * The `battery' plugin should work on many Apple computers now.
704 * The `traffic' plugin can now ignore certain interfaces. Also,
705 statistics for sent/received packets and errors have been added.
706 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
707 to Anthony Gialluca for contributing this plugin and providing me
708 with a test environment :)
709 * A plugin for monitoring an NTP instance and the local clock drift
712 2006-06-25, Version 3.9.4
713 * The Solaris code in the `swap' plugin has been changed to reflect
714 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
716 * The debugging system has been fixed to work with the Sun libc.
717 * When built without librrd the variable `operating_mode' could be
718 uninitialized. Thanks to David Elliot for reporting the bug.
720 2006-06-01, Version 3.9.3
721 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
722 operating systems also profit from the changes, but I wasn't able to
724 * Changed the build system to find the netinet-includes under FreeBSD
725 and therefore successfully build the `liboping' library there.
727 2006-05-09, Version 3.9.2
728 * Applied a patch to the `liboping' library. Due to a bug in the
729 sequence checking the `ping' plugin stopped working after
730 approximately 7.6 days.
732 2006-05-09, Version 3.8.5
733 * Applied a patch to the `liboping' library. Due to a bug in the
734 sequence checking the `ping' plugin stopped working after
735 approximately 7.6 days.
737 2006-04-21, Version 3.9.1
738 * Build issues with Solaris and possible other architectures have been
740 * Problems when building the `apache'-plugin without `libcurl' have
742 * A bug in the `ping' plugin has been fixed. Sorry folks.
744 2006-04-02, Version 3.9.0
745 * A plugin to monitor the Apache webserver has been added.
746 <http://httpd.apache.org/>
747 * A plugin to collect statistics about virtual servers using VServer.
748 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
750 * A plugin for wireless LAN cards has been added. It monitors signal
751 strength, link quality and noise ratio..
752 * A plugin for Apple hardware sensors has been added.
753 * An option to compile collectd with different `step' and `heartbeat'
754 settings has been added. The size of RRAs is no longer static but
755 calculated based on the settings for `step' and `width'.
756 * The `ping' plugin can now be configured to use a certain TTL.
757 * A plugin to monitor the hardware sensors of Apple computers has been
759 * The plugins `cpu', `memory', `processes' and `traffic' have been
760 ported to Mach/Darwin (Mac OS X).
761 * The `log mode' has been contributed by Christophe Kalt. It writes
762 the data into text files rather than RRD files.
764 2006-04-09, Version 3.8.4
765 * Applied patch by Vincent Stehlé which improves the disk-name
766 resolution in the `hddtemp' plugin for Linux systems.
768 2006-04-02, Version 3.8.3
769 * Applied a patch by James Byers: The MySQL plugin was not working
770 with MySQL 5.0.2 or later.
772 2006-03-14, Version 3.8.2
773 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
774 the GNU libc, because it points to `/etc/fstab' rather than
777 2006-03-13, Version 3.8.1
778 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
779 * Fixes in the debian `postinst' and `init.d' scripts.
781 2006-03-09, Version 3.8.0
782 * The `ping' plugin no longer uses `libping' but a self written
783 library named `liboping'. With this library it's possible to ping
784 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
786 2006-02-18, Version 3.7.2
787 * A simple bug in the `battery' plugin has been fixed. It should now
788 work with ACPI based batteries as well. Thanks to Sebastian for
790 * Fixing a bug that prevented collectd to be built without librrd.
791 Thanks to Werner Heuser for reporting it.
793 2006-02-04, Version 3.7.1
794 * The new network code has been improved to build with older versions
796 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
797 to Tommie Gannert for this patch.
799 2006-01-30, Version 3.7.0
800 * The `battery' plugin has been added. It collects information about
802 * The MySQL plugin has been improved: It now writes two more RRD
803 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
804 * The `cpufreq' plugin now reads another file since the file it did
805 read so far causes much overhead in the kernel. Also, you need root
806 to read the old file, but not to read the new one.
807 * The `hddtemp' plugin can now be configured to connect to another
808 address and/or port than localhost.
809 * The `df' plugin now prefers `statvfs' over `statfs'.
810 * The network code has been rewritten. collectd now supports unicast
811 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
812 be set in the configfile.
814 2006-01-24, Version 3.6.2
815 * Due to a bug in the configfile handling collectd wouldn't start in
816 client mode. This released fixes this.
818 2006-01-20, Version 3.6.1
819 * Due to a bug in `configure.in' all modules and the binary were
820 linked against `libmysqlclient'. This issue is solved by this
823 2006-01-17, Version 3.6.0
824 * A config file has been added. This allows for loading only specific
826 * A `df' plugin has been added.
827 * A `mysql' plugin has been added.
828 * The `ping' plugin doesn't entirely give up hope when a socket error
829 occurred, but will back of and increase the intervals between tries.
831 2006-01-21, Version 3.5.2
832 * Fixed yet another bug in the signal handling.. Stupid typo..
833 * Improved the ping plugin to not give up on socket errors (backport
836 2005-12-18, Version 3.5.1
837 * The PID-file is now deleted correctly when shutting down the daemon.
838 * SIGINT and SIGTERM are now handled correctly.
840 2005-12-16, Version 3.5.0 (Revision 326)
841 * A bug in the `load' module under Solaris has been fixed.
842 * The `users' module has been contributed by Sebastian Harl. It counts
843 currently logged in users.
844 * The CPU module now works under FreeBSD without the use of
845 `libstatgrab', however SMP support is missing.
846 * The default directories for the RRD files and the PID file now
847 depend on the compile time setting of `localstatedir'.
849 2005-11-15, Version 3.4.0 (Revision 236)
850 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
851 from gentoo's bugzilla for writing the patch.
852 * The build dependency for librrd has been removed. Binaries built
853 without librrd are client-only and will multicast their value as
854 with the `-c' argument.
855 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
856 * The newly introduced `-f' switch prevents daemon initialization
857 (forking, closing standard filehandles, etc.) Thanks to Alvaro
858 Barcellos for this patch.
860 2005-11-04, Version 3.3.0 (Revision 216)
861 * New modules have been added:
862 - `serial', for monitoring traffic on the serial interfaces
863 - `nfs', for graphing NFS procedure calls
864 - `tape', traffic from/to tape devices
865 * The memory.rrd now accepts more than 4Gig of memory.
867 2005-10-26, Version 3.2.0 (Revision 200)
868 * Support for graphing the processes has been added (thanks to Lyonel

873 * Problems with the spec file have been fixed.
875 2005-10-16, Version 3.1.0 (Revision 194)
876 * Added the `setsid' syscall to the startup code.
877 * Support for hddtemp has been added (thanks to Vincent Stehlé)
879 2005-09-30, Version 3.0.0 (Revision 184)
880 * The ability to send/receive data to/from the network (think
881 multicast) has been added.
882 * Modules have been split up into shared libraries can be loaded at
883 runtime. The biggest advantage is that the core program doesn't need
884 to be linked against an external library.
885 * A patch by George Kargiotakis has been applied: It fixes the sensors
886 behaviour then more than one sensor is being queried.
888 2005-09-16, Version 2.1.0 (Revision 172)
889 * A module for swap statistics has been added.
891 2005-09-09, Version 2.0.0 (Revision 135)
892 * Filenames can no longer be configured at program startup. The only
893 options as of this version are the directory and ping hosts.
894 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
895 Soft-IRQ statistics are added to `System'.
896 * Diskstats now collect read and write bytes, not sectors.
897 * Ping statistics can now be collected for more than one host. There
898 is no default any more: If no host is given no host will be pinged.
899 * A self-written patch for libping has been applied so it builds
902 2005-09-01, Version 1.8.1 (Revision 123)
903 * Much improved configure-script: libraries and features may now be
905 * More detailed warnings/error messages when RRD update fails.
907 2005-08-29, Version 1.8.0:
908 * Support for collecting disk statistics under Solaris.
910 2005-08-25, Version 1.7.0:
911 * Support for libstatgrab[1] for load, memory usage and network
912 traffic. CPU- and disk-usage are not (yet) supported, since
913 libstatgrab returns insufficient information. I will contact the
915 * Improved the CPU-initialization code for Solaris. Apparently CPUs
916 aren't necessarily counted linear which is now handled correctly.
917 [1]: http://www.i-scream.org/libstatgrab/
919 2005-08-21, Version 1.6.0:
920 * Basic support for Solaris: System load and cpu-usage can be
921 collected under Solaris, too. Other stats will follow later.
922 * Many fixes in the autoconf-script
923 * Collection/Museum scripts have been added under contrib/museum
924 * collectd may now be started in unprivileged mode, though ping
925 statistics will not work.
927 2005-07-17, Version 1.5.1:
928 * Diskstats-RRDs now use major/minor for naming. Some systems have
929 weird strings as disk-names..
931 2005-07-17, Version 1.5:
932 * A new module, diskstats, has been added. It collects information
933 about the disks and partitions.
935 2005-07-11, Version 1.4.2:
936 * The meminfo module has been changed to work with more platforms
937 and/or kernel versions.
939 2005-07-10, Version 1.4.1: Correct traffic stats
940 * The traffic rrd-file is now created with DS-type `COUNTER' which I
941 forgot to correct when I changed that module.
943 2005-07-09, Version 1.4: More traffic stats
944 * Traffic is now collected for all interfaces that can be found
945 * Temperature-statistics are read from lm-sensors if available
947 2005-07-08, Version 1.3: CPU stats
948 * Collecting CPU statistics now
950 2004-07-12, Version 1.2: Using syslog
951 * collectd is now using the syslog facility to report errors, warnings
953 * The default directory is now /var/db/collectd
955 2004-07-10, Version 1.1: Minor changes
956 * Nothing really useful to say ;)
958 2004-07-09, Version 1.0: Initial Version
959 * The following modules are provided:
projects / collectd.git / blob
