1 yyyy-mm-dd, Version 4.2.0
2 * collectd: The new config option `Include' lets you include other
3 configfiles and thus split up your config into smaller parts. This
4 may be especially interresting for the snmp plugin to keep the data
5 definitions seperate from the host definitions.
6 * perl plugin: Many changes, including the added `EnableDebugger'
7 config option which lets you debug your Perl plugins more easily.
8 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
9 correct the values returned by SNMP-agents.
11 2007-09-28, Version 4.1.2

28 with the broken GNU version of `strerror_r'.
29 * collectd: Write an error message to STDERR when loading of a plugin
31 * apcups plugin: Fix the `types' used to submit the values: They still
32 has an `apcups_' prefix which doesn't work anymore.

34 whatever the client thinks is `now'..
36 2007-09-01, Version 4.1.0
37 * Build system: The build system has been changed to automatically
38 disable all plugins, which are missing dependencies. The dependency
39 checking has been removed from the plugins themselves to remove
41 * Flexible interval: The interval of collected data is now sent along
42 with the data itself over the network, so that the interval-settings
43 of server and clients no longer needs to match.
44 * netlink plugin: The new `netlink' plugin connects to the Linux
45 kernel using a netlink socket and uses it to query information about
46 interfaces, qdiscs and classes.
47 * rrdtool plugin: The cache is now dumped to disk in an extra thread
48 to not block data collection.
49 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
50 network devices, such as switches, routers, thermometers, rack
51 monitoring servers, etc. The collectd-snmp(5) manpage documents this
53 * unixsock plugin: Added the `LISTVAL' command.
54 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
55 of music played with xmms.

69 has an `apcups_' prefix which doesn't work anymore.
70 * rrdtool plugin: Create new RRD-files with the `begin' time set to
71 whatever the client thinks is `now'..
73 2007-08-26, Version 4.0.7
74 * documentation: Some typos have been fixed and some information has
76 * build system: Many fixes for detecting libraries in unusual places,
77 such as on RedHat systems. The affected libraries are `libcurl',
78 `libmysql', and `libupsclient'.
79 * network plugin: Allow the `Port' option to be specified as a number
80 (i. e. without quotes).
81 * nut plugin: A fix allows linking the nut plugin against
82 libupsclient, version >= 2.2.0.
83 * processes plugin: Fix a potential segmentation fault.
85 2007-07-30, Version 4.0.6
86 * sensors plugin: Fix the ignorelist functionality: Only the `type
87 instance' was used to match against the list, but the documentation
88 told otherwise. This release fixes the code, so it complies with the
90 * syslog plugin: Call `openlog' right when the plugin is loaded, so
91 configuration messages will end up in the logging facility.
92 * conrtib/fedora: The contributed specfile for Fedora has been
95 2007-07-05, Version 4.0.5
96 * Portability: More fixes for OpenBSD have been included.

119 Setting a comment in the configfile will no longer cause a
122 2007-06-03, Version 4.0.0
123 * collectd: The plugin-infrastructure has been changed to allow for
124 more types of plugins, namely `write' and `log' plugins.
125 * collectd: The read-function has been changed to read many plugins in
126 parallel, using threads. Thus, plugins generally need to use
127 thread-safe functions from now on.
128 * collectd: The '-t' command line options allows to perform syntax tests
129 of the configuration file and exit immediately.
130 * csv plugin: The new `csv' plugin handles output to `comma separated
132 * rrdtool plugin: The new `rrdtool' plugin handles output to
133 RRD-files. Data can be cached to combine multiple updates into one
134 write to increase IO-performance.
135 * network plugin: The new `network' plugin handles IO via the network.
136 It implements a different, much more extensible protocol which can
137 combine many values in one packet, decreasing the number of UDP-
138 packets being sent. It can read from and send to the network and
139 with the appropriate configuration even forward packets to other
141 * unixsock plugin: The new `unixsock' plugin provides an interface to
142 communicate with the daemon while it is running. Right now the
143 commands `GETVAL' and `PUTVAL' are implemented, but more are to
145 * perl plugin: The new `perl' plugin allows you to write extensions
146 for collectd in the scripting-language Perl.
147 * logfile plugin: The new `logfile' plugin writes logmessages to files
149 * syslog plugin: The new `syslog' plugin sends logmessages to the

158 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
159 to Peter Holik for contributing this plugin.
160 * nut plugin: The new `nut' plugin connects the upsd of the `network
161 ups tools' and reads information about the connected UPS.
162 * apache plugin: Support for lighttpd's `BusyServers' (aka.
163 connections) field was added by Florent Monbillard.
164 * collectd-nagios: The new `collectd-nagios' binary queries values
165 from collectd, parses them and exits according to Nagios-standards.
166 * manpages: The manpages have been improved a lot.
168 2007-09-28, Version 3.11.7
169 * wireless plugin: Correct the handling of cards returning signal and
170 noise quality as percentage.
172 2007-08-31, Version 3.11.6

176 * configure: Added `AC_SYS_LARGEFILE' for LFS.
177 * ntpd plugin: Fix a potential buffer overflow.
178 * processes plugin: Fix a bug when run under Linux 2.4. All processes
179 were accounted as `zombies'.
181 2007-04-10, Version 3.11.4
182 * dns plugin: Change the order of includes to make the plugin compile
185 2007-03-30, Version 3.11.3
186 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
187 of the unused `COLLECT_KSTAT'.
189 2007-02-11, Version 3.11.2
190 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
191 NULL-pointer may have been passed to `printf' which causes a
192 segfault with some libcs.
194 2007-02-10, Version 3.11.1
195 * df plugin: Some wrong defines have been fixed so the plugin works
197 * dns plugin: The usage of a struct has been fixed to work with
199 * processes plugin: Some missing defines have been added so the plugin
200 compiles cleanly under FreeBSD and presumably other UNIXes.
202 2006-12-22, Version 3.11.0
203 * collectd: The new command line option `-P' makes it easier for
204 distributors to change the location of PID-files.
205 * collectd: The daemon shuts down faster now which makes it easier to
206 write init.d-scripts for it.
207 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
208 caused problems every now and then.
209 * df plugin: New config options allow to ignore certain mountpoints,
210 filesystem types or devices.
211 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
212 and interprets it. It collects traffic as well as qtype, opcode and
214 * email plugin: Sebastian Harl has contributed this plugin which
215 counts received mails in categories (e. g. ham, spam, virus), spam
216 score (as given by SpamAssassin) and check types.
217 * mbmon plugin: Flavio Stanchina has contributed this plugin which
218 uses `mbmon' to gather information from sensors on the motherboard.
219 * processes plugin: Collect detailed statistics for configured
220 processes, that's process and thread count, CPU usage, resident
221 segment size and pagefaults.
222 * multimeter plugin: Peter Holik contributed a new plugin which
224 * sensors plugin: Lubos Stanek has put much effort into improving this
225 plugin, including `extended naming', collection of voltage values
226 and the possibility to ignore certain values.
228 2006-12-21, Version 3.10.4
229 * Max Kellermann has identified a bug in the server routine: When
230 opening a socket fails the daemon will (re)try opening the socket in
231 an endless loop, ultimately leading to a `EMFILE' error.
233 2006-11-04, Version 3.10.3
234 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
235 ntpd's reply was sent in more than one packet, the buffer size was
236 calculated incorrectly, resulting in the reading of uninitialized or
239 2006-11-01, Version 3.10.2
240 * The sample config file has been improved.
241 * Errors in the manpages have been corrected.
242 * The ping-plugin now adds hosts during initialization, not during
243 startup. This speeds up starup when no network connectivity is
244 available. Also, the hosts are being added later when the network is
246 * Improved BSD-support for the df-plugin.
247 * Fixed syntax errors in the swap-plugin for Mac OS X.
248 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
250 * Don't disable the mysql-plugin if connecting to the database fails
251 during initialization. Instead, try again in increasing intervals.
253 2006-07-19, Version 3.10.1
254 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
255 the apcups cannot be reached, unconnected sockets will pile up and
256 eventually lead to `Too many open files' errors.
258 2006-07-09, Version 3.10.0
259 * The `disk' plugin has been ported to Darwin.
260 * The `battery' plugin should work on many Apple computers now.
261 * The `traffic' plugin can now ignore certain interfaces. Also,
262 statistics for sent/received packets and errors have been added.
263 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
264 to Anthony Gialluca for contributing this plugin and providing me
265 with a test environment :)
266 * A plugin for moniroting an NTP instance and the local clock drift
269 2006-06-25, Version 3.9.4
270 * The Solaris code in the `swap' plugin has been changed to reflect
271 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
273 * The debugging system has been fixed to work with the Sun libc.
274 * When built without librrd the variable `operating_mode' could be
275 uninitialized. Thanks to David Elliot for reporting the bug.
277 2006-06-01, Version 3.9.3
278 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
279 operating systems also profit from the changes, but I wasn't able to
281 * Changed the build system to find the netinet-includes under FreeBSD
282 and therefore successfully build the `liboping' library there.
284 2006-05-09, Version 3.9.2
285 * Applied a patch to the `liboping' library. Due to a bug in the
286 sequence checking the `ping' plugin stopped working after
287 approximately 7.6 days.
289 2006-05-09, Version 3.8.5
290 * Applied a patch to the `liboping' library. Due to a bug in the
291 sequence checking the `ping' plugin stopped working after
292 approximately 7.6 days.
294 2006-04-21, Version 3.9.1
295 * Build issues with Solaris and possible other architectures have been
297 * Problems when building the `apache'-plugin without `libcurl' have

308 strength, link quality and noise ratio..
309 * A plugin for Apple hardware sensors has been added.
310 * An option to compile collectd with different `step' and `hearbeat'
311 settings has been added. The size of RRAs is no longer static but
312 calculated based on the settings for `step' and `width'.
313 * The `ping' plugin can now be configured to use a certain TTL.
314 * A plugin to monitor the hardware sensors of Apple computers has been
316 * The plugins `cpu', `memory', `processes' and `traffic' have been
317 ported to Mach/Darwin (Mac OS X).
318 * The `log mode' has been contributed by Christophe Kalt. It writes
319 the data into text files rather than RRD files.
321 2006-04-09, Version 3.8.4
322 * Applied patch by Vincent Stehlé which improves the disk-name
323 resolution in the `hddtemp' plugin for Linux systems.
325 2006-04-02, Version 3.8.3
326 * Applied a patch by James Byers: The MySQL plugin was not working
327 with MySQL 5.0.2 or later.
329 2006-03-14, Version 3.8.2
330 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
331 the GNU libc, because it points to `/etc/fstab' rather than
334 2006-03-13, Version 3.8.1
335 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
336 * Fixes in the debian `postinst' and `init.d' scripts.
338 2006-03-09, Version 3.8.0
339 * The `ping' plugin no longer uses `libping' but a self written
340 library named `liboping'. With this library it's possible to ping
341 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
343 2006-02-18, Version 3.7.2
344 * A simple bug in the `battery' plugin has been fixed. It should now
345 work with ACPI based batteries as well. Thankt to Sebastian for
347 * Fixing a bug that prevented collectd to be built without librrd.
348 Thanks to Werner Heuser for reporting it.
350 2006-02-04, Version 3.7.1
351 * The new network code has been improved to build with older versions

356 2006-01-30, Version 3.7.0
357 * The `battery' plugin has been added. It collects information about
359 * The MySQL plugin has been improved: It now writes two more RRD
360 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
361 * The `cpufreq' plugin now reads another file since the file it did
362 read so far causes much overhead in the kernel. Also, you need root
363 to read the old file, but not to read the new one.
364 * The `hddtemp' plugin can now be configured to connect to another
365 address and/or port than localhost.
366 * The `df' plugin now prefers `statvfs' over `statfs'.
367 * The network code has been rewritten. collectd now supports unicast
368 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
369 be set in the configfile.
371 2006-01-24, Version 3.6.2
372 * Due to a bug in the configfile handling collectd wouldn't start in
373 client mode. This released fixes this.
375 2006-01-20, Version 3.6.1
376 * Due to a bug in `configure.in' all modules and the binary were
377 linked against `libmysqlclient'. This issue is solved by this
380 2006-01-17, Version 3.6.0
381 * A config file has been added. This allows for loading only specific
383 * A `df' plugin has been added.
384 * A `mysql' plugin has been added.
385 * The `ping' plugin doesn't entirely give up hope when a socket error
386 occured, but will back of and increase the intervals between tries.
388 2006-01-21, Version 3.5.2
389 * Fixed yet another bug in the signal handling.. Stupid typo..
390 * Improved the ping plugin to not give up on socket errors (backport
393 2005-12-18, Version 3.5.1
394 * The PID-file is now deleted correctly when shutting down the daemon.
395 * SIGINT and SIGTERM are now handled correctly.
397 2005-12-16, Version 3.5.0 (Revision 326)
398 * A bug in the `load' module under Solaris has been fixed.
399 * The `users' module has been contributed by Sebastian Harl. It counts
400 currently logged in users.
401 * The CPU module now works under FreeBSD without the use of
402 `libstatgrab', however SMP support is missing.
403 * The default directories for the RRD files and the PID file now
404 depend on the compile time setting of `localstatedir'.
406 2005-11-15, Version 3.4.0 (Revision 236)
407 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
408 from gentoo's bugzilla for writing the patch.
409 * The build dependency for librrd has been removed. Binaries built
410 without librrd are client-only and will multicast their value as
411 with the `-c' argument.
412 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
413 * The newly introduced `-f' switch prevents daemon initialization
414 (forking, closing standard filehandles, etc.) Thanks to Alvaro
415 Barcellos for this patch.
417 2005-11-04, Version 3.3.0 (Revision 216)
418 * New modules have been added:
419 - `serial', for monitoring traffic on the serial interfaces
420 - `nfs', for graphing NFS procedure calls
421 - `tape', traffic from/to tape devices

432 2005-10-16, Version 3.1.0 (Revision 194)
433 * Added the `setsid' syscall to the startup code.
434 * Support for hddtemp has been added (thanks to Vincent Stehlé)
436 2005-09-30, Version 3.0.0 (Revision 184)
437 * The ability to send/receive data to/from the network (think
438 multicast) has been added.
439 * Modules have been split up into shared libraries can be loaded at
440 runtime. The biggest advantage is that the core program doesn't need
441 to be linked against an external library.
442 * A patch by George Kargiotakis has been applied: It fixes the sensors
443 behaviour then more than one sensor is being queried.
445 2005-09-16, Version 2.1.0 (Revision 172)
446 * A module for swap statistics has been added.
448 2005-09-09, Version 2.0.0 (Revision 135)
449 * Filenames can no longer be configured at program startup. The only
450 options as of this version are the directory and ping hosts.
451 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
452 Soft-IRQ statistics are added to `System'.
453 * Diskstats now collect read and write bytes, not sectors.
454 * Ping statistics can now be collected for more than one host. There
455 is no default any more: If no host is given no host will be pinged.
456 * A self-written patch for libping has been applied so it builds
459 2005-09-01, Version 1.8.1 (Revision 123)
460 * Much improved configure-script: libraries and features may now be
462 * More detailed warnings/error messages when RRD update failes.
464 2005-08-29, Version 1.8.0:
465 * Support for collecting disk statistics under Solaris.
467 2005-08-25, Version 1.7.0:
468 * Support for libstatgrab[1] for load, memory usage and network
469 traffic. CPU- and disk-usage are not (yet) supported, since
470 libstatgrab returns insufficient information. I will contact the
472 * Improved the CPU-initialization code for Solaris. Apparently CPUs
473 aren't neccessarily counted linear which is now handled correctly.
474 [1]: http://www.i-scream.org/libstatgrab/
476 2005-08-21, Version 1.6.0:
477 * Basic support for Solaris: System load and cpu-usage can be
478 collected unter Solaris, too. Other stats will follow later.
479 * Many fixes in the autoconf-script
480 * Collection/Museum scripts have been added unter contrib/museum
481 * collectd may now be started in unprivileged mode, though ping
482 statistics will not work.
484 2005-07-17, Version 1.5.1:
485 * Diskstats-RRDs now use major/minor for naming. Some systems have
486 weird strings as disk-names..
488 2005-07-17, Version 1.5:
489 * A new module, diskstats, has been added. It collects information
490 about the disks and partitions.
492 2005-07-11, Version 1.4.2:
493 * The meminfo mofule has been changed to work with more platforms
494 and/or kernel versions.
496 2005-07-10, Version 1.4.1: Correct traffic stats
497 * The traffic rrd-file is now created with DS-type `COUNTER' which I
498 forgot to correct when I changed that module.
500 2005-07-09, Version 1.4: More traffic stats
501 * Traffic is now collected for all interfaces that can be found
502 * Temperature-statistics are read from lm-sensors if available

512 2004-07-10, Version 1.1: Minor changes
513 * Nothing really usefull to say ;)
515 2004-07-09, Version 1.0: Initial Version
516 * The following modules are provided:
