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.
10 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
11 (number of connections, octets and packets for each service and

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

85 * build system: Many fixes for detecting libraries in unusual places,
86 such as on RedHat systems. The affected libraries are `libcurl',
87 `libmysql', and `libupsclient'.
88 * network plugin: Allow the `Port' option to be specified as a number
89 (i. e. without quotes).
90 * nut plugin: A fix allows linking the nut plugin against
91 libupsclient, version >= 2.2.0.
92 * processes plugin: Fix a potential segmentation fault.
94 2007-07-30, Version 4.0.6
95 * sensors plugin: Fix the ignorelist functionality: Only the `type
96 instance' was used to match against the list, but the documentation
97 told otherwise. This release fixes the code, so it complies with the
99 * syslog plugin: Call `openlog' right when the plugin is loaded, so
100 configuration messages will end up in the logging facility.
101 * conrtib/fedora: The contributed specfile for Fedora has been
104 2007-07-05, Version 4.0.5

128 Setting a comment in the configfile will no longer cause a
131 2007-06-03, Version 4.0.0
132 * collectd: The plugin-infrastructure has been changed to allow for
133 more types of plugins, namely `write' and `log' plugins.
134 * collectd: The read-function has been changed to read many plugins in
135 parallel, using threads. Thus, plugins generally need to use

137 * collectd: The '-t' command line options allows to perform syntax tests
138 of the configuration file and exit immediately.
139 * csv plugin: The new `csv' plugin handles output to `comma separated

142 RRD-files. Data can be cached to combine multiple updates into one
143 write to increase IO-performance.
144 * network plugin: The new `network' plugin handles IO via the network.
145 It implements a different, much more extensible protocol which can
146 combine many values in one packet, decreasing the number of UDP-
147 packets being sent. It can read from and send to the network and
148 with the appropriate configuration even forward packets to other
150 * unixsock plugin: The new `unixsock' plugin provides an interface to
151 communicate with the daemon while it is running. Right now the
152 commands `GETVAL' and `PUTVAL' are implemented, but more are to
154 * perl plugin: The new `perl' plugin allows you to write extensions
155 for collectd in the scripting-language Perl.

168 to Peter Holik for contributing this plugin.
169 * nut plugin: The new `nut' plugin connects the upsd of the `network
170 ups tools' and reads information about the connected UPS.
171 * apache plugin: Support for lighttpd's `BusyServers' (aka.
172 connections) field was added by Florent Monbillard.
173 * collectd-nagios: The new `collectd-nagios' binary queries values
174 from collectd, parses them and exits according to Nagios-standards.
175 * manpages: The manpages have been improved a lot.
177 2007-09-28, Version 3.11.7
178 * wireless plugin: Correct the handling of cards returning signal and

185 * configure: Added `AC_SYS_LARGEFILE' for LFS.
186 * ntpd plugin: Fix a potential buffer overflow.
187 * processes plugin: Fix a bug when run under Linux 2.4. All processes
188 were accounted as `zombies'.
190 2007-04-10, Version 3.11.4
191 * dns plugin: Change the order of includes to make the plugin compile
194 2007-03-30, Version 3.11.3
195 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
196 of the unused `COLLECT_KSTAT'.
198 2007-02-11, Version 3.11.2
199 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
200 NULL-pointer may have been passed to `printf' which causes a
201 segfault with some libcs.
203 2007-02-10, Version 3.11.1
204 * df plugin: Some wrong defines have been fixed so the plugin works
206 * dns plugin: The usage of a struct has been fixed to work with
208 * processes plugin: Some missing defines have been added so the plugin
209 compiles cleanly under FreeBSD and presumably other UNIXes.
211 2006-12-22, Version 3.11.0
212 * collectd: The new command line option `-P' makes it easier for
213 distributors to change the location of PID-files.
214 * collectd: The daemon shuts down faster now which makes it easier to
215 write init.d-scripts for it.
216 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
217 caused problems every now and then.
218 * df plugin: New config options allow to ignore certain mountpoints,
219 filesystem types or devices.
220 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
221 and interprets it. It collects traffic as well as qtype, opcode and
223 * email plugin: Sebastian Harl has contributed this plugin which
224 counts received mails in categories (e. g. ham, spam, virus), spam
225 score (as given by SpamAssassin) and check types.
226 * mbmon plugin: Flavio Stanchina has contributed this plugin which
227 uses `mbmon' to gather information from sensors on the motherboard.
228 * processes plugin: Collect detailed statistics for configured
229 processes, that's process and thread count, CPU usage, resident
230 segment size and pagefaults.
231 * multimeter plugin: Peter Holik contributed a new plugin which
233 * sensors plugin: Lubos Stanek has put much effort into improving this
234 plugin, including `extended naming', collection of voltage values
235 and the possibility to ignore certain values.
237 2006-12-21, Version 3.10.4
238 * Max Kellermann has identified a bug in the server routine: When
239 opening a socket fails the daemon will (re)try opening the socket in
240 an endless loop, ultimately leading to a `EMFILE' error.
242 2006-11-04, Version 3.10.3
243 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
244 ntpd's reply was sent in more than one packet, the buffer size was
245 calculated incorrectly, resulting in the reading of uninitialized or
248 2006-11-01, Version 3.10.2
249 * The sample config file has been improved.
250 * Errors in the manpages have been corrected.
251 * The ping-plugin now adds hosts during initialization, not during
252 startup. This speeds up starup when no network connectivity is
253 available. Also, the hosts are being added later when the network is
255 * Improved BSD-support for the df-plugin.
256 * Fixed syntax errors in the swap-plugin for Mac OS X.
257 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
259 * Don't disable the mysql-plugin if connecting to the database fails
260 during initialization. Instead, try again in increasing intervals.
262 2006-07-19, Version 3.10.1
263 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
264 the apcups cannot be reached, unconnected sockets will pile up and
265 eventually lead to `Too many open files' errors.
267 2006-07-09, Version 3.10.0
268 * The `disk' plugin has been ported to Darwin.
269 * The `battery' plugin should work on many Apple computers now.

273 to Anthony Gialluca for contributing this plugin and providing me
274 with a test environment :)
275 * A plugin for moniroting an NTP instance and the local clock drift
278 2006-06-25, Version 3.9.4
279 * The Solaris code in the `swap' plugin has been changed to reflect
280 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
282 * The debugging system has been fixed to work with the Sun libc.
283 * When built without librrd the variable `operating_mode' could be
284 uninitialized. Thanks to David Elliot for reporting the bug.
286 2006-06-01, Version 3.9.3
287 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
288 operating systems also profit from the changes, but I wasn't able to
290 * Changed the build system to find the netinet-includes under FreeBSD
291 and therefore successfully build the `liboping' library there.
293 2006-05-09, Version 3.9.2
294 * Applied a patch to the `liboping' library. Due to a bug in the
295 sequence checking the `ping' plugin stopped working after
296 approximately 7.6 days.
298 2006-05-09, Version 3.8.5
299 * Applied a patch to the `liboping' library. Due to a bug in the
300 sequence checking the `ping' plugin stopped working after
301 approximately 7.6 days.
303 2006-04-21, Version 3.9.1
304 * Build issues with Solaris and possible other architectures have been
306 * Problems when building the `apache'-plugin without `libcurl' have

317 strength, link quality and noise ratio..
318 * A plugin for Apple hardware sensors has been added.
319 * An option to compile collectd with different `step' and `hearbeat'
320 settings has been added. The size of RRAs is no longer static but
321 calculated based on the settings for `step' and `width'.
322 * The `ping' plugin can now be configured to use a certain TTL.
323 * A plugin to monitor the hardware sensors of Apple computers has been
325 * The plugins `cpu', `memory', `processes' and `traffic' have been
326 ported to Mach/Darwin (Mac OS X).
327 * The `log mode' has been contributed by Christophe Kalt. It writes
328 the data into text files rather than RRD files.
330 2006-04-09, Version 3.8.4
331 * Applied patch by Vincent Stehlé which improves the disk-name
332 resolution in the `hddtemp' plugin for Linux systems.
334 2006-04-02, Version 3.8.3

336 with MySQL 5.0.2 or later.
338 2006-03-14, Version 3.8.2
339 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
340 the GNU libc, because it points to `/etc/fstab' rather than
343 2006-03-13, Version 3.8.1
344 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
345 * Fixes in the debian `postinst' and `init.d' scripts.
347 2006-03-09, Version 3.8.0
348 * The `ping' plugin no longer uses `libping' but a self written
349 library named `liboping'. With this library it's possible to ping
350 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
352 2006-02-18, Version 3.7.2
353 * A simple bug in the `battery' plugin has been fixed. It should now
354 work with ACPI based batteries as well. Thankt to Sebastian for

368 * The MySQL plugin has been improved: It now writes two more RRD
369 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
370 * The `cpufreq' plugin now reads another file since the file it did
371 read so far causes much overhead in the kernel. Also, you need root
372 to read the old file, but not to read the new one.
373 * The `hddtemp' plugin can now be configured to connect to another
374 address and/or port than localhost.
375 * The `df' plugin now prefers `statvfs' over `statfs'.
376 * The network code has been rewritten. collectd now supports unicast
377 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
378 be set in the configfile.
380 2006-01-24, Version 3.6.2
381 * Due to a bug in the configfile handling collectd wouldn't start in
382 client mode. This released fixes this.
384 2006-01-20, Version 3.6.1
385 * Due to a bug in `configure.in' all modules and the binary were
386 linked against `libmysqlclient'. This issue is solved by this
389 2006-01-17, Version 3.6.0
390 * A config file has been added. This allows for loading only specific
392 * A `df' plugin has been added.
393 * A `mysql' plugin has been added.
394 * The `ping' plugin doesn't entirely give up hope when a socket error
395 occured, but will back of and increase the intervals between tries.
397 2006-01-21, Version 3.5.2
398 * Fixed yet another bug in the signal handling.. Stupid typo..
399 * Improved the ping plugin to not give up on socket errors (backport

407 * A bug in the `load' module under Solaris has been fixed.
408 * The `users' module has been contributed by Sebastian Harl. It counts
409 currently logged in users.
410 * The CPU module now works under FreeBSD without the use of
411 `libstatgrab', however SMP support is missing.
412 * The default directories for the RRD files and the PID file now
413 depend on the compile time setting of `localstatedir'.
415 2005-11-15, Version 3.4.0 (Revision 236)
416 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
417 from gentoo's bugzilla for writing the patch.
418 * The build dependency for librrd has been removed. Binaries built
419 without librrd are client-only and will multicast their value as
420 with the `-c' argument.
421 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
422 * The newly introduced `-f' switch prevents daemon initialization
423 (forking, closing standard filehandles, etc.) Thanks to Alvaro
424 Barcellos for this patch.
426 2005-11-04, Version 3.3.0 (Revision 216)
427 * New modules have been added:
428 - `serial', for monitoring traffic on the serial interfaces
429 - `nfs', for graphing NFS procedure calls
430 - `tape', traffic from/to tape devices

445 2005-09-30, Version 3.0.0 (Revision 184)
446 * The ability to send/receive data to/from the network (think
447 multicast) has been added.
448 * Modules have been split up into shared libraries can be loaded at
449 runtime. The biggest advantage is that the core program doesn't need
450 to be linked against an external library.
451 * A patch by George Kargiotakis has been applied: It fixes the sensors
452 behaviour then more than one sensor is being queried.
454 2005-09-16, Version 2.1.0 (Revision 172)
455 * A module for swap statistics has been added.
457 2005-09-09, Version 2.0.0 (Revision 135)
458 * Filenames can no longer be configured at program startup. The only
459 options as of this version are the directory and ping hosts.
460 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
461 Soft-IRQ statistics are added to `System'.
462 * Diskstats now collect read and write bytes, not sectors.
463 * Ping statistics can now be collected for more than one host. There
464 is no default any more: If no host is given no host will be pinged.
465 * A self-written patch for libping has been applied so it builds
468 2005-09-01, Version 1.8.1 (Revision 123)
469 * Much improved configure-script: libraries and features may now be
471 * More detailed warnings/error messages when RRD update failes.
473 2005-08-29, Version 1.8.0:
474 * Support for collecting disk statistics under Solaris.
476 2005-08-25, Version 1.7.0:
477 * Support for libstatgrab[1] for load, memory usage and network
478 traffic. CPU- and disk-usage are not (yet) supported, since
479 libstatgrab returns insufficient information. I will contact the
481 * Improved the CPU-initialization code for Solaris. Apparently CPUs
482 aren't neccessarily counted linear which is now handled correctly.
483 [1]: http://www.i-scream.org/libstatgrab/
485 2005-08-21, Version 1.6.0:
486 * Basic support for Solaris: System load and cpu-usage can be
487 collected unter Solaris, too. Other stats will follow later.
488 * Many fixes in the autoconf-script
489 * Collection/Museum scripts have been added unter contrib/museum
490 * collectd may now be started in unprivileged mode, though ping
491 statistics will not work.
493 2005-07-17, Version 1.5.1:
494 * Diskstats-RRDs now use major/minor for naming. Some systems have
495 weird strings as disk-names..
497 2005-07-17, Version 1.5:
498 * A new module, diskstats, has been added. It collects information
499 about the disks and partitions.
501 2005-07-11, Version 1.4.2:
502 * The meminfo mofule has been changed to work with more platforms
503 and/or kernel versions.
505 2005-07-10, Version 1.4.1: Correct traffic stats
506 * The traffic rrd-file is now created with DS-type `COUNTER' which I
507 forgot to correct when I changed that module.
509 2005-07-09, Version 1.4: More traffic stats
510 * Traffic is now collected for all interfaces that can be found
511 * Temperature-statistics are read from lm-sensors if available
