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 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
7 correct the values returned by SNMP-agents.
9 yyyy-mm-dd, Version 4.1.2

20 with the broken GNU version of `strerror_r'.
21 * collectd: Write an error message to STDERR when loading of a plugin
23 * apcups plugin: Fix the `types' used to submit the values: They still
24 has an `apcups_' prefix which doesn't work anymore.
25 * rrdtool plugin: Create new RRD-files with the `begin' time set to
26 whatever the client thinks is `now'..
28 2007-09-01, Version 4.1.0
29 * Build system: The build system has been changed to automatically
30 disable all plugins, which are missing dependencies. The dependency
31 checking has been removed from the plugins themselves to remove
33 * Flexible interval: The interval of collected data is now sent along
34 with the data itself over the network, so that the interval-settings
35 of server and clients no longer needs to match.
36 * netlink plugin: The new `netlink' plugin connects to the Linux
37 kernel using a netlink socket and uses it to query information about
38 interfaces, qdiscs and classes.
39 * rrdtool plugin: The cache is now dumped to disk in an extra thread
40 to not block data collection.
41 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
42 network devices, such as switches, routers, thermometers, rack
43 monitoring servers, etc. The collectd-snmp(5) manpage documents this
45 * unixsock plugin: Added the `LISTVAL' command.
46 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
47 of music played with xmms.
49 yyyy-mm-dd, Version 4.0.9
50 * apcups plugin: Fix reporting of the `load percent' data.
52 2007-09-12, Version 4.0.8

54 with the broken GNU version of `strerror_r'.
55 * collectd: Write an error message to STDERR when loading of a plugin
57 * apcups plugin: Fix the `types' used to submit the values: They still
58 has an `apcups_' prefix which doesn't work anymore.
59 * rrdtool plugin: Create new RRD-files with the `begin' time set to
60 whatever the client thinks is `now'..
62 2007-08-26, Version 4.0.7
63 * documentation: Some typos have been fixed and some information has
65 * build system: Many fixes for detecting libraries in unusual places,
66 such as on RedHat systems. The affected libraries are `libcurl',
67 `libmysql', and `libupsclient'.
68 * network plugin: Allow the `Port' option to be specified as a number
69 (i. e. without quotes).
70 * nut plugin: A fix allows linking the nut plugin against
71 libupsclient, version >= 2.2.0.
72 * processes plugin: Fix a potential segmentation fault.
74 2007-07-30, Version 4.0.6
75 * sensors plugin: Fix the ignorelist functionality: Only the `type
76 instance' was used to match against the list, but the documentation
77 told otherwise. This release fixes the code, so it complies with the
79 * syslog plugin: Call `openlog' right when the plugin is loaded, so
80 configuration messages will end up in the logging facility.
81 * conrtib/fedora: The contributed specfile for Fedora has been
84 2007-07-05, Version 4.0.5
85 * Portability: More fixes for OpenBSD have been included.
87 2007-06-24, Version 4.0.4

108 Setting a comment in the configfile will no longer cause a
111 2007-06-03, Version 4.0.0
112 * collectd: The plugin-infrastructure has been changed to allow for
113 more types of plugins, namely `write' and `log' plugins.
114 * collectd: The read-function has been changed to read many plugins in
115 parallel, using threads. Thus, plugins generally need to use
116 thread-safe functions from now on.
117 * collectd: The '-t' command line options allows to perform syntax tests
118 of the configuration file and exit immediately.
119 * csv plugin: The new `csv' plugin handles output to `comma separated
121 * rrdtool plugin: The new `rrdtool' plugin handles output to
122 RRD-files. Data can be cached to combine multiple updates into one
123 write to increase IO-performance.
124 * network plugin: The new `network' plugin handles IO via the network.
125 It implements a different, much more extensible protocol which can
126 combine many values in one packet, decreasing the number of UDP-
127 packets being sent. It can read from and send to the network and
128 with the appropriate configuration even forward packets to other
130 * unixsock plugin: The new `unixsock' plugin provides an interface to
131 communicate with the daemon while it is running. Right now the
132 commands `GETVAL' and `PUTVAL' are implemented, but more are to
134 * perl plugin: The new `perl' plugin allows you to write extensions
135 for collectd in the scripting-language Perl.
136 * logfile plugin: The new `logfile' plugin writes logmessages to files
138 * syslog plugin: The new `syslog' plugin sends logmessages to the
139 system's syslog daemon.
140 * entropy plugin: The new `entropy' plugin collects the amount of
141 entropy currently being available to the system.
142 * exec plugin: The new `exec' plugin forks child processes and reads
143 back values provided by the forked processes.
144 * iptables plugin: The new `iptables' plugin reads counters from
145 iptables rules. Thanks to Sjoerd van der Berg for contributing this
147 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
148 to Peter Holik for contributing this plugin.
149 * nut plugin: The new `nut' plugin connects the upsd of the `network
150 ups tools' and reads information about the connected UPS.
151 * apache plugin: Support for lighttpd's `BusyServers' (aka.
152 connections) field was added by Florent Monbillard.
153 * collectd-nagios: The new `collectd-nagios' binary queries values
154 from collectd, parses them and exits according to Nagios-standards.
155 * manpages: The manpages have been improved a lot.
157 2007-08-31, Version 3.11.6
158 * processes plugin: Fix a potential segmentation fault.

161 * configure: Added `AC_SYS_LARGEFILE' for LFS.
162 * ntpd plugin: Fix a potential buffer overflow.
163 * processes plugin: Fix a bug when run under Linux 2.4. All processes
164 were accounted as `zombies'.
166 2007-04-10, Version 3.11.4
167 * dns plugin: Change the order of includes to make the plugin compile
170 2007-03-30, Version 3.11.3
171 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
172 of the unused `COLLECT_KSTAT'.
174 2007-02-11, Version 3.11.2
175 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
176 NULL-pointer may have been passed to `printf' which causes a
177 segfault with some libcs.
179 2007-02-10, Version 3.11.1
180 * df plugin: Some wrong defines have been fixed so the plugin works
182 * dns plugin: The usage of a struct has been fixed to work with
184 * processes plugin: Some missing defines have been added so the plugin
185 compiles cleanly under FreeBSD and presumably other UNIXes.
187 2006-12-22, Version 3.11.0
188 * collectd: The new command line option `-P' makes it easier for
189 distributors to change the location of PID-files.
190 * collectd: The daemon shuts down faster now which makes it easier to
191 write init.d-scripts for it.
192 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
193 caused problems every now and then.
194 * df plugin: New config options allow to ignore certain mountpoints,
195 filesystem types or devices.
196 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
197 and interprets it. It collects traffic as well as qtype, opcode and
199 * email plugin: Sebastian Harl has contributed this plugin which
200 counts received mails in categories (e. g. ham, spam, virus), spam
201 score (as given by SpamAssassin) and check types.
202 * mbmon plugin: Flavio Stanchina has contributed this plugin which
203 uses `mbmon' to gather information from sensors on the motherboard.
204 * processes plugin: Collect detailed statistics for configured
205 processes, that's process and thread count, CPU usage, resident
206 segment size and pagefaults.
207 * multimeter plugin: Peter Holik contributed a new plugin which
209 * sensors plugin: Lubos Stanek has put much effort into improving this
210 plugin, including `extended naming', collection of voltage values
211 and the possibility to ignore certain values.
213 2006-12-21, Version 3.10.4
214 * Max Kellermann has identified a bug in the server routine: When
215 opening a socket fails the daemon will (re)try opening the socket in
216 an endless loop, ultimately leading to a `EMFILE' error.
218 2006-11-04, Version 3.10.3
219 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
220 ntpd's reply was sent in more than one packet, the buffer size was
221 calculated incorrectly, resulting in the reading of uninitialized or
224 2006-11-01, Version 3.10.2
225 * The sample config file has been improved.
226 * Errors in the manpages have been corrected.
227 * The ping-plugin now adds hosts during initialization, not during
228 startup. This speeds up starup when no network connectivity is
229 available. Also, the hosts are being added later when the network is
231 * Improved BSD-support for the df-plugin.
232 * Fixed syntax errors in the swap-plugin for Mac OS X.
233 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
235 * Don't disable the mysql-plugin if connecting to the database fails
236 during initialization. Instead, try again in increasing intervals.
238 2006-07-19, Version 3.10.1
239 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
240 the apcups cannot be reached, unconnected sockets will pile up and
241 eventually lead to `Too many open files' errors.
243 2006-07-09, Version 3.10.0
244 * The `disk' plugin has been ported to Darwin.
245 * The `battery' plugin should work on many Apple computers now.
246 * The `traffic' plugin can now ignore certain interfaces. Also,
247 statistics for sent/received packets and errors have been added.
248 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
249 to Anthony Gialluca for contributing this plugin and providing me
250 with a test environment :)
251 * A plugin for moniroting an NTP instance and the local clock drift
254 2006-06-25, Version 3.9.4
255 * The Solaris code in the `swap' plugin has been changed to reflect
256 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
258 * The debugging system has been fixed to work with the Sun libc.
259 * When built without librrd the variable `operating_mode' could be
260 uninitialized. Thanks to David Elliot for reporting the bug.
262 2006-06-01, Version 3.9.3
263 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
264 operating systems also profit from the changes, but I wasn't able to
266 * Changed the build system to find the netinet-includes under FreeBSD
267 and therefore successfully build the `liboping' library there.
269 2006-05-09, Version 3.9.2
270 * Applied a patch to the `liboping' library. Due to a bug in the
271 sequence checking the `ping' plugin stopped working after
272 approximately 7.6 days.
274 2006-05-09, Version 3.8.5
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 2006-04-21, Version 3.9.1
280 * Build issues with Solaris and possible other architectures have been
282 * Problems when building the `apache'-plugin without `libcurl' have

293 strength, link quality and noise ratio..
294 * A plugin for Apple hardware sensors has been added.
295 * An option to compile collectd with different `step' and `hearbeat'
296 settings has been added. The size of RRAs is no longer static but
297 calculated based on the settings for `step' and `width'.
298 * The `ping' plugin can now be configured to use a certain TTL.
299 * A plugin to monitor the hardware sensors of Apple computers has been
301 * The plugins `cpu', `memory', `processes' and `traffic' have been
302 ported to Mach/Darwin (Mac OS X).
303 * The `log mode' has been contributed by Christophe Kalt. It writes
304 the data into text files rather than RRD files.
306 2006-04-09, Version 3.8.4
307 * Applied patch by Vincent Stehlé which improves the disk-name
308 resolution in the `hddtemp' plugin for Linux systems.
310 2006-04-02, Version 3.8.3
311 * Applied a patch by James Byers: The MySQL plugin was not working
312 with MySQL 5.0.2 or later.
314 2006-03-14, Version 3.8.2
315 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
316 the GNU libc, because it points to `/etc/fstab' rather than
319 2006-03-13, Version 3.8.1
320 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
321 * Fixes in the debian `postinst' and `init.d' scripts.
323 2006-03-09, Version 3.8.0
324 * The `ping' plugin no longer uses `libping' but a self written
325 library named `liboping'. With this library it's possible to ping
326 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
328 2006-02-18, Version 3.7.2
329 * A simple bug in the `battery' plugin has been fixed. It should now
330 work with ACPI based batteries as well. Thankt to Sebastian for
332 * Fixing a bug that prevented collectd to be built without librrd.
333 Thanks to Werner Heuser for reporting it.
335 2006-02-04, Version 3.7.1
336 * The new network code has been improved to build with older versions

341 2006-01-30, Version 3.7.0
342 * The `battery' plugin has been added. It collects information about
344 * The MySQL plugin has been improved: It now writes two more RRD
345 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
346 * The `cpufreq' plugin now reads another file since the file it did
347 read so far causes much overhead in the kernel. Also, you need root
348 to read the old file, but not to read the new one.
349 * The `hddtemp' plugin can now be configured to connect to another
350 address and/or port than localhost.
351 * The `df' plugin now prefers `statvfs' over `statfs'.
352 * The network code has been rewritten. collectd now supports unicast
353 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
354 be set in the configfile.
356 2006-01-24, Version 3.6.2
357 * Due to a bug in the configfile handling collectd wouldn't start in
358 client mode. This released fixes this.
360 2006-01-20, Version 3.6.1
361 * Due to a bug in `configure.in' all modules and the binary were
362 linked against `libmysqlclient'. This issue is solved by this
365 2006-01-17, Version 3.6.0
366 * A config file has been added. This allows for loading only specific
368 * A `df' plugin has been added.
369 * A `mysql' plugin has been added.
370 * The `ping' plugin doesn't entirely give up hope when a socket error
371 occured, but will back of and increase the intervals between tries.
373 2006-01-21, Version 3.5.2
374 * Fixed yet another bug in the signal handling.. Stupid typo..
375 * Improved the ping plugin to not give up on socket errors (backport
378 2005-12-18, Version 3.5.1
379 * The PID-file is now deleted correctly when shutting down the daemon.
380 * SIGINT and SIGTERM are now handled correctly.
382 2005-12-16, Version 3.5.0 (Revision 326)
383 * A bug in the `load' module under Solaris has been fixed.
384 * The `users' module has been contributed by Sebastian Harl. It counts
385 currently logged in users.
386 * The CPU module now works under FreeBSD without the use of
387 `libstatgrab', however SMP support is missing.
388 * The default directories for the RRD files and the PID file now
389 depend on the compile time setting of `localstatedir'.
391 2005-11-15, Version 3.4.0 (Revision 236)
392 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
393 from gentoo's bugzilla for writing the patch.
394 * The build dependency for librrd has been removed. Binaries built
395 without librrd are client-only and will multicast their value as
396 with the `-c' argument.
397 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
398 * The newly introduced `-f' switch prevents daemon initialization
399 (forking, closing standard filehandles, etc.) Thanks to Alvaro
400 Barcellos for this patch.
402 2005-11-04, Version 3.3.0 (Revision 216)
403 * New modules have been added:
404 - `serial', for monitoring traffic on the serial interfaces
405 - `nfs', for graphing NFS procedure calls
406 - `tape', traffic from/to tape devices

417 2005-10-16, Version 3.1.0 (Revision 194)
418 * Added the `setsid' syscall to the startup code.
419 * Support for hddtemp has been added (thanks to Vincent Stehlé)
421 2005-09-30, Version 3.0.0 (Revision 184)
422 * The ability to send/receive data to/from the network (think
423 multicast) has been added.
424 * Modules have been split up into shared libraries can be loaded at
425 runtime. The biggest advantage is that the core program doesn't need
426 to be linked against an external library.
427 * A patch by George Kargiotakis has been applied: It fixes the sensors
428 behaviour then more than one sensor is being queried.
430 2005-09-16, Version 2.1.0 (Revision 172)
431 * A module for swap statistics has been added.
433 2005-09-09, Version 2.0.0 (Revision 135)
434 * Filenames can no longer be configured at program startup. The only
435 options as of this version are the directory and ping hosts.
436 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
437 Soft-IRQ statistics are added to `System'.
438 * Diskstats now collect read and write bytes, not sectors.
439 * Ping statistics can now be collected for more than one host. There
440 is no default any more: If no host is given no host will be pinged.
441 * A self-written patch for libping has been applied so it builds
444 2005-09-01, Version 1.8.1 (Revision 123)
445 * Much improved configure-script: libraries and features may now be
447 * More detailed warnings/error messages when RRD update failes.
449 2005-08-29, Version 1.8.0:
450 * Support for collecting disk statistics under Solaris.
452 2005-08-25, Version 1.7.0:
453 * Support for libstatgrab[1] for load, memory usage and network
454 traffic. CPU- and disk-usage are not (yet) supported, since
455 libstatgrab returns insufficient information. I will contact the
457 * Improved the CPU-initialization code for Solaris. Apparently CPUs
458 aren't neccessarily counted linear which is now handled correctly.
459 [1]: http://www.i-scream.org/libstatgrab/
461 2005-08-21, Version 1.6.0:
462 * Basic support for Solaris: System load and cpu-usage can be
463 collected unter Solaris, too. Other stats will follow later.
464 * Many fixes in the autoconf-script
465 * Collection/Museum scripts have been added unter contrib/museum
466 * collectd may now be started in unprivileged mode, though ping
467 statistics will not work.
469 2005-07-17, Version 1.5.1:
470 * Diskstats-RRDs now use major/minor for naming. Some systems have
471 weird strings as disk-names..
473 2005-07-17, Version 1.5:
474 * A new module, diskstats, has been added. It collects information
475 about the disks and partitions.
477 2005-07-11, Version 1.4.2:
478 * The meminfo mofule has been changed to work with more platforms
479 and/or kernel versions.
481 2005-07-10, Version 1.4.1: Correct traffic stats
482 * The traffic rrd-file is now created with DS-type `COUNTER' which I
483 forgot to correct when I changed that module.
485 2005-07-09, Version 1.4: More traffic stats
486 * Traffic is now collected for all interfaces that can be found
487 * Temperature-statistics are read from lm-sensors if available
489 2005-07-08, Version 1.3: CPU stats
490 * Collecting CPU statistics now
492 2004-07-12, Version 1.2: Using syslog
493 * collectd is now using the syslog facility to report errors, warnings
495 * The default directory is now /var/db/collectd
497 2004-07-10, Version 1.1: Minor changes
498 * Nothing really usefull to say ;)
500 2004-07-09, Version 1.0: Initial Version
501 * The following modules are provided:
