1 2007-12-15, Version 4.2.2
2 * nginx plugin: Incorrect comparison of strings lead to a segfault
3 when using the plugin. Thanks to Saulius Grigaliunas for fixing
5 * logfile plugin: The config option `Timestamp' was handled
6 incorrectly and basically always active. Thanks to Luke Heberling
9 2007-11-08, Version 4.2.1
10 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
12 * snmp plugin: Fix a memory leak.
14 2007-10-27, Version 4.2.0
15 * collectd: The new config option `Include' lets you include other
16 configfiles and thus split up your config into smaller parts. This
17 may be especially interesting for the snmp plugin to keep the data
18 definitions separate from the host definitions.
19 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
20 (number of connections, octets and packets for each service and
21 destination). Thanks to Sebastian Harl for this plugin.
22 * memcached plugin: The new `memcached' plugin connects to a memcached
23 daemon process and collects statistics of this distributed caching
24 system. Thanks to Antony Dovgal for contributing this plugin.
25 * nginx plugin: The new `nginx' plugin reads the status page of an
26 nginx daemon and saves the handled connections and requests.
27 * perl plugin: Many changes, including the added `EnableDebugger'
28 config option which lets you debug your Perl plugins more easily.
29 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
30 be more thread-safe otherwise by locking calls to the library.
31 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
32 correct the values returned by SNMP-agents. If a <data> block is
33 defined as `table' the instance is now optional. The sequence number
34 is used as the type-instance in this case. The new `InstancePrefix'
35 option allows to add arbitrary prefixes to the type-instance.
36 * tcpconns plugin: The new `tcpconns' plugin collects the number of
37 certain TCP connections and what state they're in. This can be used
38 to see how many connections your FTP server has to handle or how
39 many outgoing connections your mailserver has open.
41 2007-11-08, Version 4.1.4
42 * Build system: Improve detection of the rrd library, especially if
43 it's in a non-standard location.
44 * Build system: A bug when parsing the argument for
45 `--with-libnetsnmp' has been fixed.
46 * collectd: Implement `strerror_r' if the libc doesn't provide it.
47 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
48 a deadlock or delay when shutting down the daemon.
49 * snmp plugin: Fix a memory leak.
51 2007-10-24, Version 4.1.3
52 * collectd: A build issue under Solaris has been resolved by renaming
54 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
55 be more thread-safe otherwise by locking calls to the library.
57 2007-09-28, Version 4.1.2
58 * apcups plugin: Fix reporting of the `load percent' data.
59 * wireless plugin: Correct the handling of cards returning signal and

66 support for the `timeticks' type.
68 2007-09-12, Version 4.1.1
69 * Build system: The detection of `libnetlink' has been improved.
70 * collectd: The documentation has been fixed in numerous places.
71 * exec plugin: Setting the group under which to run a program has been
73 * collectd: The `sstrerror' function was improved to work correctly
74 with the broken GNU version of `strerror_r'.
75 * collectd: Write an error message to STDERR when loading of a plugin
77 * apcups plugin: Fix the `types' used to submit the values: They still
78 has an `apcups_' prefix which doesn't work anymore.
79 * rrdtool plugin: Create new RRD-files with the `begin' time set to
80 whatever the client thinks is `now'..
82 2007-09-01, Version 4.1.0
83 * Build system: The build system has been changed to automatically
84 disable all plugins, which are missing dependencies. The dependency
85 checking has been removed from the plugins themselves to remove
87 * Flexible interval: The interval of collected data is now sent along
88 with the data itself over the network, so that the interval-settings
89 of server and clients no longer needs to match.
90 * netlink plugin: The new `netlink' plugin connects to the Linux
91 kernel using a netlink socket and uses it to query information about
92 interfaces, qdiscs and classes.
93 * rrdtool plugin: The cache is now dumped to disk in an extra thread
94 to not block data collection.
95 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
96 network devices, such as switches, routers, thermometers, rack
97 monitoring servers, etc. The collectd-snmp(5) manpage documents this
99 * unixsock plugin: Added the `LISTVAL' command.
100 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
101 of music played with xmms.
103 2007-09-28, Version 4.0.9
104 * apcups plugin: Fix reporting of the `load percent' data.
105 * wireless plugin: Correct the handling of cards returning signal and
106 noise quality as percentage.
107 * perl plugin: Fix a possible buffer overflow in get_module_name().
109 2007-09-12, Version 4.0.8

111 with the broken GNU version of `strerror_r'.
112 * collectd: Write an error message to STDERR when loading of a plugin
114 * apcups plugin: Fix the `types' used to submit the values: They still
115 has an `apcups_' prefix which doesn't work anymore.
116 * rrdtool plugin: Create new RRD-files with the `begin' time set to
117 whatever the client thinks is `now'..
119 2007-08-26, Version 4.0.7
120 * documentation: Some typos have been fixed and some information has
122 * build system: Many fixes for detecting libraries in unusual places,
123 such as on RedHat systems. The affected libraries are `libcurl',
124 `libmysql', and `libupsclient'.
125 * network plugin: Allow the `Port' option to be specified as a number
126 (i. e. without quotes).
127 * nut plugin: A fix allows linking the nut plugin against
128 libupsclient, version >= 2.2.0.
129 * processes plugin: Fix a potential segmentation fault.
131 2007-07-30, Version 4.0.6
132 * sensors plugin: Fix the ignorelist functionality: Only the `type
133 instance' was used to match against the list, but the documentation
134 told otherwise. This release fixes the code, so it complies with the
136 * syslog plugin: Call `openlog' right when the plugin is loaded, so
137 configuration messages will end up in the logging facility.
138 * conrtib/fedora: The contributed specfile for Fedora has been
141 2007-07-05, Version 4.0.5
142 * Portability: More fixes for OpenBSD have been included.

161 they're given in numerically form.
163 2007-06-07, Version 4.0.1
164 * iptables plugin: A bug in the configuration routine has been fixed.
165 Setting a comment in the configfile will no longer cause a
168 2007-06-03, Version 4.0.0
169 * collectd: The plugin-infrastructure has been changed to allow for
170 more types of plugins, namely `write' and `log' plugins.
171 * collectd: The read-function has been changed to read many plugins in
172 parallel, using threads. Thus, plugins generally need to use
173 thread-safe functions from now on.
174 * collectd: The '-t' command line options allows to perform syntax tests
175 of the configuration file and exit immediately.
176 * csv plugin: The new `csv' plugin handles output to `comma separated
178 * rrdtool plugin: The new `rrdtool' plugin handles output to
179 RRD-files. Data can be cached to combine multiple updates into one
180 write to increase IO-performance.
181 * network plugin: The new `network' plugin handles IO via the network.
182 It implements a different, much more extensible protocol which can
183 combine many values in one packet, decreasing the number of UDP-
184 packets being sent. It can read from and send to the network and
185 with the appropriate configuration even forward packets to other
187 * unixsock plugin: The new `unixsock' plugin provides an interface to
188 communicate with the daemon while it is running. Right now the
189 commands `GETVAL' and `PUTVAL' are implemented, but more are to
191 * perl plugin: The new `perl' plugin allows you to write extensions
192 for collectd in the scripting-language Perl.
193 * logfile plugin: The new `logfile' plugin writes logmessages to files
195 * syslog plugin: The new `syslog' plugin sends logmessages to the
196 system's syslog daemon.
197 * entropy plugin: The new `entropy' plugin collects the amount of
198 entropy currently being available to the system.
199 * exec plugin: The new `exec' plugin forks child processes and reads
200 back values provided by the forked processes.
201 * iptables plugin: The new `iptables' plugin reads counters from
202 iptables rules. Thanks to Sjoerd van der Berg for contributing this
204 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
205 to Peter Holik for contributing this plugin.
206 * nut plugin: The new `nut' plugin connects the upsd of the `network
207 ups tools' and reads information about the connected UPS.
208 * apache plugin: Support for lighttpd's `BusyServers' (aka.
209 connections) field was added by Florent Monbillard.
210 * collectd-nagios: The new `collectd-nagios' binary queries values
211 from collectd, parses them and exits according to Nagios-standards.
212 * manpages: The manpages have been improved a lot.
214 2007-09-28, Version 3.11.7
215 * wireless plugin: Correct the handling of cards returning signal and
216 noise quality as percentage.
218 2007-08-31, Version 3.11.6

222 * configure: Added `AC_SYS_LARGEFILE' for LFS.
223 * ntpd plugin: Fix a potential buffer overflow.
224 * processes plugin: Fix a bug when run under Linux 2.4. All processes
225 were accounted as `zombies'.
227 2007-04-10, Version 3.11.4
228 * dns plugin: Change the order of includes to make the plugin compile
231 2007-03-30, Version 3.11.3
232 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
233 of the unused `COLLECT_KSTAT'.
235 2007-02-11, Version 3.11.2
236 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
237 NULL-pointer may have been passed to `printf' which causes a
238 segfault with some libcs.
240 2007-02-10, Version 3.11.1
241 * df plugin: Some wrong defines have been fixed so the plugin works
243 * dns plugin: The usage of a struct has been fixed to work with
245 * processes plugin: Some missing defines have been added so the plugin
246 compiles cleanly under FreeBSD and presumably other UNIXes.
248 2006-12-22, Version 3.11.0
249 * collectd: The new command line option `-P' makes it easier for
250 distributors to change the location of PID-files.
251 * collectd: The daemon shuts down faster now which makes it easier to
252 write init.d-scripts for it.
253 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
254 caused problems every now and then.
255 * df plugin: New config options allow to ignore certain mountpoints,
256 filesystem types or devices.
257 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
258 and interprets it. It collects traffic as well as qtype, opcode and
260 * email plugin: Sebastian Harl has contributed this plugin which
261 counts received mails in categories (e. g. ham, spam, virus), spam
262 score (as given by SpamAssassin) and check types.
263 * mbmon plugin: Flavio Stanchina has contributed this plugin which
264 uses `mbmon' to gather information from sensors on the motherboard.
265 * processes plugin: Collect detailed statistics for configured
266 processes, that's process and thread count, CPU usage, resident
267 segment size and pagefaults.
268 * multimeter plugin: Peter Holik contributed a new plugin which
270 * sensors plugin: Lubos Stanek has put much effort into improving this
271 plugin, including `extended naming', collection of voltage values
272 and the possibility to ignore certain values.
274 2006-12-21, Version 3.10.4
275 * Max Kellermann has identified a bug in the server routine: When
276 opening a socket fails the daemon will (re)try opening the socket in
277 an endless loop, ultimately leading to a `EMFILE' error.
279 2006-11-04, Version 3.10.3
280 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
281 ntpd's reply was sent in more than one packet, the buffer size was
282 calculated incorrectly, resulting in the reading of uninitialized or
285 2006-11-01, Version 3.10.2
286 * The sample config file has been improved.
287 * Errors in the manpages have been corrected.
288 * The ping-plugin now adds hosts during initialization, not during
289 startup. This speeds up startup when no network connectivity is
290 available. Also, the hosts are being added later when the network is
292 * Improved BSD-support for the df-plugin.
293 * Fixed syntax errors in the swap-plugin for Mac OS X.
294 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
296 * Don't disable the mysql-plugin if connecting to the database fails
297 during initialization. Instead, try again in increasing intervals.
299 2006-07-19, Version 3.10.1
300 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
301 the apcups cannot be reached, unconnected sockets will pile up and
302 eventually lead to `Too many open files' errors.
304 2006-07-09, Version 3.10.0
305 * The `disk' plugin has been ported to Darwin.
306 * The `battery' plugin should work on many Apple computers now.
307 * The `traffic' plugin can now ignore certain interfaces. Also,
308 statistics for sent/received packets and errors have been added.
309 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
310 to Anthony Gialluca for contributing this plugin and providing me
311 with a test environment :)
312 * A plugin for monitoring an NTP instance and the local clock drift
315 2006-06-25, Version 3.9.4
316 * The Solaris code in the `swap' plugin has been changed to reflect
317 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
319 * The debugging system has been fixed to work with the Sun libc.
320 * When built without librrd the variable `operating_mode' could be
321 uninitialized. Thanks to David Elliot for reporting the bug.
323 2006-06-01, Version 3.9.3
324 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
325 operating systems also profit from the changes, but I wasn't able to
327 * Changed the build system to find the netinet-includes under FreeBSD
328 and therefore successfully build the `liboping' library there.
330 2006-05-09, Version 3.9.2
331 * Applied a patch to the `liboping' library. Due to a bug in the
332 sequence checking the `ping' plugin stopped working after
333 approximately 7.6 days.
335 2006-05-09, Version 3.8.5
336 * Applied a patch to the `liboping' library. Due to a bug in the
337 sequence checking the `ping' plugin stopped working after
338 approximately 7.6 days.
340 2006-04-21, Version 3.9.1
341 * Build issues with Solaris and possible other architectures have been
343 * Problems when building the `apache'-plugin without `libcurl' have

354 strength, link quality and noise ratio..
355 * A plugin for Apple hardware sensors has been added.
356 * An option to compile collectd with different `step' and `heartbeat'
357 settings has been added. The size of RRAs is no longer static but
358 calculated based on the settings for `step' and `width'.
359 * The `ping' plugin can now be configured to use a certain TTL.
360 * A plugin to monitor the hardware sensors of Apple computers has been
362 * The plugins `cpu', `memory', `processes' and `traffic' have been
363 ported to Mach/Darwin (Mac OS X).
364 * The `log mode' has been contributed by Christophe Kalt. It writes
365 the data into text files rather than RRD files.
367 2006-04-09, Version 3.8.4
368 * Applied patch by Vincent Stehlé which improves the disk-name
369 resolution in the `hddtemp' plugin for Linux systems.
371 2006-04-02, Version 3.8.3
372 * Applied a patch by James Byers: The MySQL plugin was not working
373 with MySQL 5.0.2 or later.
375 2006-03-14, Version 3.8.2
376 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
377 the GNU libc, because it points to `/etc/fstab' rather than
380 2006-03-13, Version 3.8.1
381 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
382 * Fixes in the debian `postinst' and `init.d' scripts.
384 2006-03-09, Version 3.8.0
385 * The `ping' plugin no longer uses `libping' but a self written
386 library named `liboping'. With this library it's possible to ping
387 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
389 2006-02-18, Version 3.7.2
390 * A simple bug in the `battery' plugin has been fixed. It should now
391 work with ACPI based batteries as well. Thanks to Sebastian for
393 * Fixing a bug that prevented collectd to be built without librrd.
394 Thanks to Werner Heuser for reporting it.
396 2006-02-04, Version 3.7.1
397 * The new network code has been improved to build with older versions

402 2006-01-30, Version 3.7.0
403 * The `battery' plugin has been added. It collects information about
405 * The MySQL plugin has been improved: It now writes two more RRD
406 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
407 * The `cpufreq' plugin now reads another file since the file it did
408 read so far causes much overhead in the kernel. Also, you need root
409 to read the old file, but not to read the new one.
410 * The `hddtemp' plugin can now be configured to connect to another
411 address and/or port than localhost.
412 * The `df' plugin now prefers `statvfs' over `statfs'.
413 * The network code has been rewritten. collectd now supports unicast
414 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
415 be set in the configfile.
417 2006-01-24, Version 3.6.2
418 * Due to a bug in the configfile handling collectd wouldn't start in
419 client mode. This released fixes this.
421 2006-01-20, Version 3.6.1
422 * Due to a bug in `configure.in' all modules and the binary were
423 linked against `libmysqlclient'. This issue is solved by this
426 2006-01-17, Version 3.6.0
427 * A config file has been added. This allows for loading only specific
429 * A `df' plugin has been added.
430 * A `mysql' plugin has been added.
431 * The `ping' plugin doesn't entirely give up hope when a socket error
432 occurred, but will back of and increase the intervals between tries.
434 2006-01-21, Version 3.5.2
435 * Fixed yet another bug in the signal handling.. Stupid typo..
436 * Improved the ping plugin to not give up on socket errors (backport
439 2005-12-18, Version 3.5.1
440 * The PID-file is now deleted correctly when shutting down the daemon.
441 * SIGINT and SIGTERM are now handled correctly.
443 2005-12-16, Version 3.5.0 (Revision 326)
444 * A bug in the `load' module under Solaris has been fixed.
445 * The `users' module has been contributed by Sebastian Harl. It counts
446 currently logged in users.
447 * The CPU module now works under FreeBSD without the use of
448 `libstatgrab', however SMP support is missing.
449 * The default directories for the RRD files and the PID file now
450 depend on the compile time setting of `localstatedir'.
452 2005-11-15, Version 3.4.0 (Revision 236)
453 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
454 from gentoo's bugzilla for writing the patch.
455 * The build dependency for librrd has been removed. Binaries built
456 without librrd are client-only and will multicast their value as
457 with the `-c' argument.
458 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
459 * The newly introduced `-f' switch prevents daemon initialization
460 (forking, closing standard filehandles, etc.) Thanks to Alvaro
461 Barcellos for this patch.
463 2005-11-04, Version 3.3.0 (Revision 216)
464 * New modules have been added:
465 - `serial', for monitoring traffic on the serial interfaces
466 - `nfs', for graphing NFS procedure calls
467 - `tape', traffic from/to tape devices

480 * Support for hddtemp has been added (thanks to Vincent Stehlé)
482 2005-09-30, Version 3.0.0 (Revision 184)
483 * The ability to send/receive data to/from the network (think
484 multicast) has been added.
485 * Modules have been split up into shared libraries can be loaded at
486 runtime. The biggest advantage is that the core program doesn't need
487 to be linked against an external library.
488 * A patch by George Kargiotakis has been applied: It fixes the sensors
489 behaviour then more than one sensor is being queried.
491 2005-09-16, Version 2.1.0 (Revision 172)
492 * A module for swap statistics has been added.
494 2005-09-09, Version 2.0.0 (Revision 135)
495 * Filenames can no longer be configured at program startup. The only
496 options as of this version are the directory and ping hosts.
497 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
498 Soft-IRQ statistics are added to `System'.
499 * Diskstats now collect read and write bytes, not sectors.
500 * Ping statistics can now be collected for more than one host. There
501 is no default any more: If no host is given no host will be pinged.
502 * A self-written patch for libping has been applied so it builds
505 2005-09-01, Version 1.8.1 (Revision 123)
506 * Much improved configure-script: libraries and features may now be
508 * More detailed warnings/error messages when RRD update fails.
510 2005-08-29, Version 1.8.0:
511 * Support for collecting disk statistics under Solaris.
513 2005-08-25, Version 1.7.0:
514 * Support for libstatgrab[1] for load, memory usage and network
515 traffic. CPU- and disk-usage are not (yet) supported, since
516 libstatgrab returns insufficient information. I will contact the
518 * Improved the CPU-initialization code for Solaris. Apparently CPUs
519 aren't necessarily counted linear which is now handled correctly.

522 2005-08-21, Version 1.6.0:
523 * Basic support for Solaris: System load and cpu-usage can be
524 collected under Solaris, too. Other stats will follow later.
525 * Many fixes in the autoconf-script
526 * Collection/Museum scripts have been added under contrib/museum
527 * collectd may now be started in unprivileged mode, though ping
528 statistics will not work.
530 2005-07-17, Version 1.5.1:

540 and/or kernel versions.
542 2005-07-10, Version 1.4.1: Correct traffic stats
543 * The traffic rrd-file is now created with DS-type `COUNTER' which I
544 forgot to correct when I changed that module.
546 2005-07-09, Version 1.4: More traffic stats
547 * Traffic is now collected for all interfaces that can be found
548 * Temperature-statistics are read from lm-sensors if available

551 * Collecting CPU statistics now
553 2004-07-12, Version 1.2: Using syslog
