26 2007-09-01, Version 4.1.0
27 * Build system: The build system has been changed to automatically
28 disable all plugins, which are missing dependencies. The dependency
29 checking has been removed from the plugins themselves to remove
31 * Flexible interval: The interval of collected data is now sent along
32 with the data itself over the network, so that the interval-settings
33 of server and clients no longer needs to match.
34 * netlink plugin: The new `netlink' plugin connects to the Linux
35 kernel using a netlink socket and uses it to query information about
36 interfaces, qdiscs and classes.
37 * rrdtool plugin: The cache is now dumped to disk in an extra thread
38 to not block data collection.
39 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
40 network devices, such as switches, routers, thermometers, rack
41 monitoring servers, etc. The collectd-snmp(5) manpage documents this
43 * unixsock plugin: Added the `LISTVAL' command.

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

109 Setting a comment in the configfile will no longer cause a
112 2007-06-03, Version 4.0.0
113 * collectd: The plugin-infrastructure has been changed to allow for
114 more types of plugins, namely `write' and `log' plugins.
115 * collectd: The read-function has been changed to read many plugins in
116 parallel, using threads. Thus, plugins generally need to use
117 thread-safe functions from now on.
118 * collectd: The '-t' command line options allows to perform syntax tests
119 of the configuration file and exit immediately.
120 * csv plugin: The new `csv' plugin handles output to `comma separated
122 * rrdtool plugin: The new `rrdtool' plugin handles output to
123 RRD-files. Data can be cached to combine multiple updates into one
124 write to increase IO-performance.
125 * network plugin: The new `network' plugin handles IO via the network.
126 It implements a different, much more extensible protocol which can
127 combine many values in one packet, decreasing the number of UDP-
128 packets being sent. It can read from and send to the network and
129 with the appropriate configuration even forward packets to other
131 * unixsock plugin: The new `unixsock' plugin provides an interface to
132 communicate with the daemon while it is running. Right now the
133 commands `GETVAL' and `PUTVAL' are implemented, but more are to
135 * perl plugin: The new `perl' plugin allows you to write extensions
136 for collectd in the scripting-language Perl.
137 * logfile plugin: The new `logfile' plugin writes logmessages to files
139 * syslog plugin: The new `syslog' plugin sends logmessages to the

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

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

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

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

346 2006-01-30, Version 3.7.0
347 * The `battery' plugin has been added. It collects information about
349 * The MySQL plugin has been improved: It now writes two more RRD
350 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
351 * The `cpufreq' plugin now reads another file since the file it did
352 read so far causes much overhead in the kernel. Also, you need root
353 to read the old file, but not to read the new one.
354 * The `hddtemp' plugin can now be configured to connect to another
355 address and/or port than localhost.
356 * The `df' plugin now prefers `statvfs' over `statfs'.
357 * The network code has been rewritten. collectd now supports unicast
358 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
359 be set in the configfile.
361 2006-01-24, Version 3.6.2
362 * Due to a bug in the configfile handling collectd wouldn't start in
363 client mode. This released fixes this.
365 2006-01-20, Version 3.6.1
366 * Due to a bug in `configure.in' all modules and the binary were
367 linked against `libmysqlclient'. This issue is solved by this
370 2006-01-17, Version 3.6.0
371 * A config file has been added. This allows for loading only specific
373 * A `df' plugin has been added.
374 * A `mysql' plugin has been added.
375 * The `ping' plugin doesn't entirely give up hope when a socket error
376 occured, but will back of and increase the intervals between tries.
378 2006-01-21, Version 3.5.2
379 * Fixed yet another bug in the signal handling.. Stupid typo..
380 * Improved the ping plugin to not give up on socket errors (backport
383 2005-12-18, Version 3.5.1

387 2005-12-16, Version 3.5.0 (Revision 326)
388 * A bug in the `load' module under Solaris has been fixed.
389 * The `users' module has been contributed by Sebastian Harl. It counts
390 currently logged in users.
391 * The CPU module now works under FreeBSD without the use of
392 `libstatgrab', however SMP support is missing.
393 * The default directories for the RRD files and the PID file now
394 depend on the compile time setting of `localstatedir'.
396 2005-11-15, Version 3.4.0 (Revision 236)
397 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
398 from gentoo's bugzilla for writing the patch.
399 * The build dependency for librrd has been removed. Binaries built
400 without librrd are client-only and will multicast their value as
401 with the `-c' argument.
402 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
403 * The newly introduced `-f' switch prevents daemon initialization
404 (forking, closing standard filehandles, etc.) Thanks to Alvaro
405 Barcellos for this patch.
407 2005-11-04, Version 3.3.0 (Revision 216)
408 * New modules have been added:
409 - `serial', for monitoring traffic on the serial interfaces
410 - `nfs', for graphing NFS procedure calls
411 - `tape', traffic from/to tape devices

422 2005-10-16, Version 3.1.0 (Revision 194)
423 * Added the `setsid' syscall to the startup code.
424 * Support for hddtemp has been added (thanks to Vincent Stehlé)
426 2005-09-30, Version 3.0.0 (Revision 184)
427 * The ability to send/receive data to/from the network (think
428 multicast) has been added.
429 * Modules have been split up into shared libraries can be loaded at
430 runtime. The biggest advantage is that the core program doesn't need
431 to be linked against an external library.
432 * A patch by George Kargiotakis has been applied: It fixes the sensors
433 behaviour then more than one sensor is being queried.
435 2005-09-16, Version 2.1.0 (Revision 172)
436 * A module for swap statistics has been added.
438 2005-09-09, Version 2.0.0 (Revision 135)
439 * Filenames can no longer be configured at program startup. The only
440 options as of this version are the directory and ping hosts.
441 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
442 Soft-IRQ statistics are added to `System'.
443 * Diskstats now collect read and write bytes, not sectors.
444 * Ping statistics can now be collected for more than one host. There
445 is no default any more: If no host is given no host will be pinged.
446 * A self-written patch for libping has been applied so it builds
449 2005-09-01, Version 1.8.1 (Revision 123)
450 * Much improved configure-script: libraries and features may now be
452 * More detailed warnings/error messages when RRD update failes.
454 2005-08-29, Version 1.8.0:
455 * Support for collecting disk statistics under Solaris.
457 2005-08-25, Version 1.7.0:
458 * Support for libstatgrab[1] for load, memory usage and network
459 traffic. CPU- and disk-usage are not (yet) supported, since
460 libstatgrab returns insufficient information. I will contact the
462 * Improved the CPU-initialization code for Solaris. Apparently CPUs
463 aren't neccessarily counted linear which is now handled correctly.
464 [1]: http://www.i-scream.org/libstatgrab/
466 2005-08-21, Version 1.6.0:
467 * Basic support for Solaris: System load and cpu-usage can be
468 collected unter Solaris, too. Other stats will follow later.
469 * Many fixes in the autoconf-script
470 * Collection/Museum scripts have been added unter contrib/museum
471 * collectd may now be started in unprivileged mode, though ping
472 statistics will not work.
474 2005-07-17, Version 1.5.1:
475 * Diskstats-RRDs now use major/minor for naming. Some systems have
476 weird strings as disk-names..
478 2005-07-17, Version 1.5:
479 * A new module, diskstats, has been added. It collects information
480 about the disks and partitions.
482 2005-07-11, Version 1.4.2:
483 * The meminfo mofule has been changed to work with more platforms
484 and/or kernel versions.
486 2005-07-10, Version 1.4.1: Correct traffic stats
487 * The traffic rrd-file is now created with DS-type `COUNTER' which I
488 forgot to correct when I changed that module.
490 2005-07-09, Version 1.4: More traffic stats
491 * Traffic is now collected for all interfaces that can be found
492 * Temperature-statistics are read from lm-sensors if available

502 2004-07-10, Version 1.1: Minor changes
503 * Nothing really usefull to say ;)
505 2004-07-09, Version 1.0: Initial Version
506 * The following modules are provided:
