29 2007-09-01, Version 4.1.0
30 * Build system: The build system has been changed to automatically
31 disable all plugins, which are missing dependencies. The dependency
32 checking has been removed from the plugins themselves to remove
34 * Flexible interval: The interval of collected data is now sent along
35 with the data itself over the network, so that the interval-settings
36 of server and clients no longer needs to match.
37 * netlink plugin: The new `netlink' plugin connects to the Linux
38 kernel using a netlink socket and uses it to query information about
39 interfaces, qdiscs and classes.
40 * rrdtool plugin: The cache is now dumped to disk in an extra thread
41 to not block data collection.
42 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
43 network devices, such as switches, routers, thermometers, rack

69 * build system: Many fixes for detecting libraries in unusual places,
70 such as on RedHat systems. The affected libraries are `libcurl',
71 `libmysql', and `libupsclient'.
72 * network plugin: Allow the `Port' option to be specified as a number
73 (i. e. without quotes).
74 * nut plugin: A fix allows linking the nut plugin against
75 libupsclient, version >= 2.2.0.
76 * processes plugin: Fix a potential segmentation fault.
78 2007-07-30, Version 4.0.6
79 * sensors plugin: Fix the ignorelist functionality: Only the `type
80 instance' was used to match against the list, but the documentation
81 told otherwise. This release fixes the code, so it complies with the
83 * syslog plugin: Call `openlog' right when the plugin is loaded, so
84 configuration messages will end up in the logging facility.
85 * conrtib/fedora: The contributed specfile for Fedora has been
88 2007-07-05, Version 4.0.5
89 * Portability: More fixes for OpenBSD have been included.

112 Setting a comment in the configfile will no longer cause a
115 2007-06-03, Version 4.0.0
116 * collectd: The plugin-infrastructure has been changed to allow for
117 more types of plugins, namely `write' and `log' plugins.
118 * collectd: The read-function has been changed to read many plugins in
119 parallel, using threads. Thus, plugins generally need to use

126 RRD-files. Data can be cached to combine multiple updates into one
127 write to increase IO-performance.
128 * network plugin: The new `network' plugin handles IO via the network.
129 It implements a different, much more extensible protocol which can
130 combine many values in one packet, decreasing the number of UDP-
131 packets being sent. It can read from and send to the network and
132 with the appropriate configuration even forward packets to other
134 * unixsock plugin: The new `unixsock' plugin provides an interface to
135 communicate with the daemon while it is running. Right now the
136 commands `GETVAL' and `PUTVAL' are implemented, but more are to
138 * perl plugin: The new `perl' plugin allows you to write extensions
139 for collectd in the scripting-language Perl.

152 to Peter Holik for contributing this plugin.
153 * nut plugin: The new `nut' plugin connects the upsd of the `network
154 ups tools' and reads information about the connected UPS.
155 * apache plugin: Support for lighttpd's `BusyServers' (aka.
156 connections) field was added by Florent Monbillard.
157 * collectd-nagios: The new `collectd-nagios' binary queries values
158 from collectd, parses them and exits according to Nagios-standards.
159 * manpages: The manpages have been improved a lot.
161 2007-09-28, Version 3.11.7
162 * wireless plugin: Correct the handling of cards returning signal and

169 * configure: Added `AC_SYS_LARGEFILE' for LFS.
170 * ntpd plugin: Fix a potential buffer overflow.
171 * processes plugin: Fix a bug when run under Linux 2.4. All processes
172 were accounted as `zombies'.
174 2007-04-10, Version 3.11.4
175 * dns plugin: Change the order of includes to make the plugin compile
178 2007-03-30, Version 3.11.3
179 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
180 of the unused `COLLECT_KSTAT'.
182 2007-02-11, Version 3.11.2
183 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
184 NULL-pointer may have been passed to `printf' which causes a
185 segfault with some libcs.
187 2007-02-10, Version 3.11.1
188 * df plugin: Some wrong defines have been fixed so the plugin works
190 * dns plugin: The usage of a struct has been fixed to work with
192 * processes plugin: Some missing defines have been added so the plugin
193 compiles cleanly under FreeBSD and presumably other UNIXes.
195 2006-12-22, Version 3.11.0
196 * collectd: The new command line option `-P' makes it easier for
197 distributors to change the location of PID-files.
198 * collectd: The daemon shuts down faster now which makes it easier to
199 write init.d-scripts for it.
200 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
201 caused problems every now and then.
202 * df plugin: New config options allow to ignore certain mountpoints,
203 filesystem types or devices.
204 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
205 and interprets it. It collects traffic as well as qtype, opcode and
207 * email plugin: Sebastian Harl has contributed this plugin which
208 counts received mails in categories (e. g. ham, spam, virus), spam
209 score (as given by SpamAssassin) and check types.
210 * mbmon plugin: Flavio Stanchina has contributed this plugin which
211 uses `mbmon' to gather information from sensors on the motherboard.
212 * processes plugin: Collect detailed statistics for configured
213 processes, that's process and thread count, CPU usage, resident
214 segment size and pagefaults.
215 * multimeter plugin: Peter Holik contributed a new plugin which
217 * sensors plugin: Lubos Stanek has put much effort into improving this
218 plugin, including `extended naming', collection of voltage values
219 and the possibility to ignore certain values.
221 2006-12-21, Version 3.10.4
222 * Max Kellermann has identified a bug in the server routine: When
223 opening a socket fails the daemon will (re)try opening the socket in
224 an endless loop, ultimately leading to a `EMFILE' error.
226 2006-11-04, Version 3.10.3
227 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
228 ntpd's reply was sent in more than one packet, the buffer size was
229 calculated incorrectly, resulting in the reading of uninitialized or
232 2006-11-01, Version 3.10.2
233 * The sample config file has been improved.
234 * Errors in the manpages have been corrected.
235 * The ping-plugin now adds hosts during initialization, not during
236 startup. This speeds up starup when no network connectivity is
237 available. Also, the hosts are being added later when the network is
239 * Improved BSD-support for the df-plugin.
240 * Fixed syntax errors in the swap-plugin for Mac OS X.
241 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
243 * Don't disable the mysql-plugin if connecting to the database fails
244 during initialization. Instead, try again in increasing intervals.
246 2006-07-19, Version 3.10.1
247 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
248 the apcups cannot be reached, unconnected sockets will pile up and
249 eventually lead to `Too many open files' errors.
251 2006-07-09, Version 3.10.0
252 * The `disk' plugin has been ported to Darwin.
253 * The `battery' plugin should work on many Apple computers now.
254 * The `traffic' plugin can now ignore certain interfaces. Also,
255 statistics for sent/received packets and errors have been added.

257 to Anthony Gialluca for contributing this plugin and providing me
258 with a test environment :)
259 * A plugin for moniroting an NTP instance and the local clock drift
262 2006-06-25, Version 3.9.4
263 * The Solaris code in the `swap' plugin has been changed to reflect
264 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
266 * The debugging system has been fixed to work with the Sun libc.
267 * When built without librrd the variable `operating_mode' could be
268 uninitialized. Thanks to David Elliot for reporting the bug.
270 2006-06-01, Version 3.9.3
271 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
272 operating systems also profit from the changes, but I wasn't able to
274 * Changed the build system to find the netinet-includes under FreeBSD
275 and therefore successfully build the `liboping' library there.
277 2006-05-09, Version 3.9.2
278 * Applied a patch to the `liboping' library. Due to a bug in the
279 sequence checking the `ping' plugin stopped working after
280 approximately 7.6 days.
282 2006-05-09, Version 3.8.5
283 * Applied a patch to the `liboping' library. Due to a bug in the
284 sequence checking the `ping' plugin stopped working after
285 approximately 7.6 days.
287 2006-04-21, Version 3.9.1
288 * Build issues with Solaris and possible other architectures have been
290 * Problems when building the `apache'-plugin without `libcurl' have

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

349 2006-01-30, Version 3.7.0
350 * The `battery' plugin has been added. It collects information about
352 * The MySQL plugin has been improved: It now writes two more RRD
353 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
354 * The `cpufreq' plugin now reads another file since the file it did
355 read so far causes much overhead in the kernel. Also, you need root
356 to read the old file, but not to read the new one.
357 * The `hddtemp' plugin can now be configured to connect to another
358 address and/or port than localhost.
359 * The `df' plugin now prefers `statvfs' over `statfs'.
360 * The network code has been rewritten. collectd now supports unicast
361 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
362 be set in the configfile.
364 2006-01-24, Version 3.6.2
365 * Due to a bug in the configfile handling collectd wouldn't start in
366 client mode. This released fixes this.
368 2006-01-20, Version 3.6.1
369 * Due to a bug in `configure.in' all modules and the binary were
370 linked against `libmysqlclient'. This issue is solved by this
373 2006-01-17, Version 3.6.0
374 * A config file has been added. This allows for loading only specific
376 * A `df' plugin has been added.
377 * A `mysql' plugin has been added.
378 * The `ping' plugin doesn't entirely give up hope when a socket error
379 occured, but will back of and increase the intervals between tries.
381 2006-01-21, Version 3.5.2
382 * Fixed yet another bug in the signal handling.. Stupid typo..
383 * Improved the ping plugin to not give up on socket errors (backport
386 2005-12-18, Version 3.5.1

390 2005-12-16, Version 3.5.0 (Revision 326)
391 * A bug in the `load' module under Solaris has been fixed.
392 * The `users' module has been contributed by Sebastian Harl. It counts
393 currently logged in users.
394 * The CPU module now works under FreeBSD without the use of
395 `libstatgrab', however SMP support is missing.
396 * The default directories for the RRD files and the PID file now
397 depend on the compile time setting of `localstatedir'.
399 2005-11-15, Version 3.4.0 (Revision 236)
400 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
401 from gentoo's bugzilla for writing the patch.
402 * The build dependency for librrd has been removed. Binaries built
403 without librrd are client-only and will multicast their value as
404 with the `-c' argument.
405 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
406 * The newly introduced `-f' switch prevents daemon initialization
407 (forking, closing standard filehandles, etc.) Thanks to Alvaro
408 Barcellos for this patch.
410 2005-11-04, Version 3.3.0 (Revision 216)
411 * New modules have been added:
412 - `serial', for monitoring traffic on the serial interfaces
413 - `nfs', for graphing NFS procedure calls
414 - `tape', traffic from/to tape devices

425 2005-10-16, Version 3.1.0 (Revision 194)
426 * Added the `setsid' syscall to the startup code.
427 * Support for hddtemp has been added (thanks to Vincent Stehlé)
429 2005-09-30, Version 3.0.0 (Revision 184)
430 * The ability to send/receive data to/from the network (think
431 multicast) has been added.
432 * Modules have been split up into shared libraries can be loaded at
433 runtime. The biggest advantage is that the core program doesn't need
434 to be linked against an external library.
435 * A patch by George Kargiotakis has been applied: It fixes the sensors
436 behaviour then more than one sensor is being queried.
438 2005-09-16, Version 2.1.0 (Revision 172)
439 * A module for swap statistics has been added.
441 2005-09-09, Version 2.0.0 (Revision 135)
442 * Filenames can no longer be configured at program startup. The only
443 options as of this version are the directory and ping hosts.
444 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
445 Soft-IRQ statistics are added to `System'.
446 * Diskstats now collect read and write bytes, not sectors.
447 * Ping statistics can now be collected for more than one host. There
448 is no default any more: If no host is given no host will be pinged.
449 * A self-written patch for libping has been applied so it builds
452 2005-09-01, Version 1.8.1 (Revision 123)
453 * Much improved configure-script: libraries and features may now be
455 * More detailed warnings/error messages when RRD update failes.
457 2005-08-29, Version 1.8.0:
458 * Support for collecting disk statistics under Solaris.
460 2005-08-25, Version 1.7.0:
461 * Support for libstatgrab[1] for load, memory usage and network
462 traffic. CPU- and disk-usage are not (yet) supported, since
463 libstatgrab returns insufficient information. I will contact the
465 * Improved the CPU-initialization code for Solaris. Apparently CPUs
466 aren't neccessarily counted linear which is now handled correctly.
467 [1]: http://www.i-scream.org/libstatgrab/
469 2005-08-21, Version 1.6.0:
470 * Basic support for Solaris: System load and cpu-usage can be
471 collected unter Solaris, too. Other stats will follow later.
472 * Many fixes in the autoconf-script
473 * Collection/Museum scripts have been added unter contrib/museum
474 * collectd may now be started in unprivileged mode, though ping
475 statistics will not work.
477 2005-07-17, Version 1.5.1:
478 * Diskstats-RRDs now use major/minor for naming. Some systems have
479 weird strings as disk-names..
481 2005-07-17, Version 1.5:
482 * A new module, diskstats, has been added. It collects information
483 about the disks and partitions.
485 2005-07-11, Version 1.4.2:
486 * The meminfo mofule has been changed to work with more platforms
487 and/or kernel versions.
489 2005-07-10, Version 1.4.1: Correct traffic stats
490 * The traffic rrd-file is now created with DS-type `COUNTER' which I
491 forgot to correct when I changed that module.
493 2005-07-09, Version 1.4: More traffic stats
494 * Traffic is now collected for all interfaces that can be found
495 * Temperature-statistics are read from lm-sensors if available
