2 * apcups plugin: Fix reporting of the `load percent' data.
4 2007-09-12, Version 4.0.8
5 * collectd: The `sstrerror' function was improved to work correctly
6 with the broken GNU version of `strerror_r'.
7 * collectd: Write an error message to STDERR when loading of a plugin
9 * apcups plugin: Fix the `types' used to submit the values: They still
10 has an `apcups_' prefix which doesn't work anymore.
11 * rrdtool plugin: Create new RRD-files with the `begin' time set to
12 whatever the client thinks is `now'..
14 2007-08-26, Version 4.0.7
15 * documentation: Some typos have been fixed and some information has
17 * build system: Many fixes for detecting libraries in unusual places,
18 such as on RedHat systems. The affected libraries are `libcurl',
19 `libmysql', and `libupsclient'.
20 * network plugin: Allow the `Port' option to be specified as a number
21 (i. e. without quotes).
22 * nut plugin: A fix allows linking the nut plugin against
23 libupsclient, version >= 2.2.0.
24 * processes plugin: Fix a potential segmentation fault.
26 2007-07-30, Version 4.0.6
27 * sensors plugin: Fix the ignorelist functionality: Only the `type
28 instance' was used to match against the list, but the documentation
29 told otherwise. This release fixes the code, so it complies with the
31 * syslog plugin: Call `openlog' right when the plugin is loaded, so
32 configuration messages will end up in the logging facility.
33 * conrtib/fedora: The contributed specfile for Fedora has been
36 2007-07-05, Version 4.0.5
37 * Portability: More fixes for OpenBSD have been included.
39 2007-06-24, Version 4.0.4

60 Setting a comment in the configfile will no longer cause a
63 2007-06-03, Version 4.0.0
64 * collectd: The plugin-infrastructure has been changed to allow for
65 more types of plugins, namely `write' and `log' plugins.
66 * collectd: The read-function has been changed to read many plugins in
67 parallel, using threads. Thus, plugins generally need to use
68 thread-safe functions from now on.
69 * collectd: The '-t' command line options allows to perform syntax tests
70 of the configuration file and exit immediately.
71 * csv plugin: The new `csv' plugin handles output to `comma separated
73 * rrdtool plugin: The new `rrdtool' plugin handles output to
74 RRD-files. Data can be cached to combine multiple updates into one
75 write to increase IO-performance.
76 * network plugin: The new `network' plugin handles IO via the network.
77 It implements a different, much more extensible protocol which can
78 combine many values in one packet, decreasing the number of UDP-
79 packets being sent. It can read from and send to the network and
80 with the appropriate configuration even forward packets to other
82 * unixsock plugin: The new `unixsock' plugin provides an interface to
83 communicate with the daemon while it is running. Right now the
84 commands `GETVAL' and `PUTVAL' are implemented, but more are to
86 * perl plugin: The new `perl' plugin allows you to write extensions
87 for collectd in the scripting-language Perl.
88 * logfile plugin: The new `logfile' plugin writes logmessages to files
90 * syslog plugin: The new `syslog' plugin sends logmessages to the
91 system's syslog daemon.
92 * entropy plugin: The new `entropy' plugin collects the amount of
93 entropy currently being available to the system.
94 * exec plugin: The new `exec' plugin forks child processes and reads
95 back values provided by the forked processes.
96 * iptables plugin: The new `iptables' plugin reads counters from
97 iptables rules. Thanks to Sjoerd van der Berg for contributing this
99 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
100 to Peter Holik for contributing this plugin.
101 * nut plugin: The new `nut' plugin connects the upsd of the `network
102 ups tools' and reads information about the connected UPS.
103 * apache plugin: Support for lighttpd's `BusyServers' (aka.
104 connections) field was added by Florent Monbillard.
105 * collectd-nagios: The new `collectd-nagios' binary queries values
106 from collectd, parses them and exits according to Nagios-standards.
107 * manpages: The manpages have been improved a lot.
109 2007-09-28, Version 3.11.7
110 * wireless plugin: Correct the handling of cards returning signal and
111 noise quality as percentage.
113 2007-08-31, Version 3.11.6

117 * configure: Added `AC_SYS_LARGEFILE' for LFS.
118 * ntpd plugin: Fix a potential buffer overflow.
119 * processes plugin: Fix a bug when run under Linux 2.4. All processes
120 were accounted as `zombies'.
122 2007-04-10, Version 3.11.4
123 * dns plugin: Change the order of includes to make the plugin compile
126 2007-03-30, Version 3.11.3
127 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
128 of the unused `COLLECT_KSTAT'.
130 2007-02-11, Version 3.11.2
131 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
132 NULL-pointer may have been passed to `printf' which causes a
133 segfault with some libcs.
135 2007-02-10, Version 3.11.1
136 * df plugin: Some wrong defines have been fixed so the plugin works
138 * dns plugin: The usage of a struct has been fixed to work with
140 * processes plugin: Some missing defines have been added so the plugin
141 compiles cleanly under FreeBSD and presumably other UNIXes.
143 2006-12-22, Version 3.11.0
144 * collectd: The new command line option `-P' makes it easier for
145 distributors to change the location of PID-files.
146 * collectd: The daemon shuts down faster now which makes it easier to
147 write init.d-scripts for it.
148 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
149 caused problems every now and then.
150 * df plugin: New config options allow to ignore certain mountpoints,
151 filesystem types or devices.
152 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
153 and interprets it. It collects traffic as well as qtype, opcode and
155 * email plugin: Sebastian Harl has contributed this plugin which
156 counts received mails in categories (e. g. ham, spam, virus), spam
157 score (as given by SpamAssassin) and check types.
158 * mbmon plugin: Flavio Stanchina has contributed this plugin which
159 uses `mbmon' to gather information from sensors on the motherboard.
160 * processes plugin: Collect detailed statistics for configured
161 processes, that's process and thread count, CPU usage, resident
162 segment size and pagefaults.
163 * multimeter plugin: Peter Holik contributed a new plugin which
165 * sensors plugin: Lubos Stanek has put much effort into improving this
166 plugin, including `extended naming', collection of voltage values
167 and the possibility to ignore certain values.
169 2006-12-21, Version 3.10.4
170 * Max Kellermann has identified a bug in the server routine: When
171 opening a socket fails the daemon will (re)try opening the socket in
172 an endless loop, ultimately leading to a `EMFILE' error.
174 2006-11-04, Version 3.10.3
175 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
176 ntpd's reply was sent in more than one packet, the buffer size was
177 calculated incorrectly, resulting in the reading of uninitialized or
180 2006-11-01, Version 3.10.2
181 * The sample config file has been improved.
182 * Errors in the manpages have been corrected.
183 * The ping-plugin now adds hosts during initialization, not during
184 startup. This speeds up starup when no network connectivity is
185 available. Also, the hosts are being added later when the network is
187 * Improved BSD-support for the df-plugin.
188 * Fixed syntax errors in the swap-plugin for Mac OS X.
189 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
191 * Don't disable the mysql-plugin if connecting to the database fails
192 during initialization. Instead, try again in increasing intervals.
194 2006-07-19, Version 3.10.1
195 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
196 the apcups cannot be reached, unconnected sockets will pile up and
197 eventually lead to `Too many open files' errors.
199 2006-07-09, Version 3.10.0
200 * The `disk' plugin has been ported to Darwin.
201 * The `battery' plugin should work on many Apple computers now.
202 * The `traffic' plugin can now ignore certain interfaces. Also,
203 statistics for sent/received packets and errors have been added.

205 to Anthony Gialluca for contributing this plugin and providing me
206 with a test environment :)
207 * A plugin for moniroting an NTP instance and the local clock drift
210 2006-06-25, Version 3.9.4
211 * The Solaris code in the `swap' plugin has been changed to reflect
212 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
214 * The debugging system has been fixed to work with the Sun libc.
215 * When built without librrd the variable `operating_mode' could be
216 uninitialized. Thanks to David Elliot for reporting the bug.
218 2006-06-01, Version 3.9.3
219 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
220 operating systems also profit from the changes, but I wasn't able to
222 * Changed the build system to find the netinet-includes under FreeBSD
223 and therefore successfully build the `liboping' library there.
225 2006-05-09, Version 3.9.2
226 * Applied a patch to the `liboping' library. Due to a bug in the
227 sequence checking the `ping' plugin stopped working after
228 approximately 7.6 days.
230 2006-05-09, Version 3.8.5
231 * Applied a patch to the `liboping' library. Due to a bug in the
232 sequence checking the `ping' plugin stopped working after
233 approximately 7.6 days.
235 2006-04-21, Version 3.9.1
236 * Build issues with Solaris and possible other architectures have been
238 * Problems when building the `apache'-plugin without `libcurl' have

249 strength, link quality and noise ratio..
250 * A plugin for Apple hardware sensors has been added.
251 * An option to compile collectd with different `step' and `hearbeat'
252 settings has been added. The size of RRAs is no longer static but
253 calculated based on the settings for `step' and `width'.
254 * The `ping' plugin can now be configured to use a certain TTL.
255 * A plugin to monitor the hardware sensors of Apple computers has been
257 * The plugins `cpu', `memory', `processes' and `traffic' have been
258 ported to Mach/Darwin (Mac OS X).
259 * The `log mode' has been contributed by Christophe Kalt. It writes
260 the data into text files rather than RRD files.
262 2006-04-09, Version 3.8.4
263 * Applied patch by Vincent Stehlé which improves the disk-name
264 resolution in the `hddtemp' plugin for Linux systems.
266 2006-04-02, Version 3.8.3
267 * Applied a patch by James Byers: The MySQL plugin was not working
268 with MySQL 5.0.2 or later.
270 2006-03-14, Version 3.8.2
271 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
272 the GNU libc, because it points to `/etc/fstab' rather than
275 2006-03-13, Version 3.8.1
276 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
277 * Fixes in the debian `postinst' and `init.d' scripts.
279 2006-03-09, Version 3.8.0
280 * The `ping' plugin no longer uses `libping' but a self written
281 library named `liboping'. With this library it's possible to ping
282 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
284 2006-02-18, Version 3.7.2
285 * A simple bug in the `battery' plugin has been fixed. It should now
286 work with ACPI based batteries as well. Thankt to Sebastian for
288 * Fixing a bug that prevented collectd to be built without librrd.
289 Thanks to Werner Heuser for reporting it.
291 2006-02-04, Version 3.7.1
292 * The new network code has been improved to build with older versions

297 2006-01-30, Version 3.7.0
298 * The `battery' plugin has been added. It collects information about
300 * The MySQL plugin has been improved: It now writes two more RRD
301 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
302 * The `cpufreq' plugin now reads another file since the file it did
303 read so far causes much overhead in the kernel. Also, you need root
304 to read the old file, but not to read the new one.
305 * The `hddtemp' plugin can now be configured to connect to another
306 address and/or port than localhost.
307 * The `df' plugin now prefers `statvfs' over `statfs'.
308 * The network code has been rewritten. collectd now supports unicast
309 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
310 be set in the configfile.
312 2006-01-24, Version 3.6.2
313 * Due to a bug in the configfile handling collectd wouldn't start in
314 client mode. This released fixes this.
316 2006-01-20, Version 3.6.1
317 * Due to a bug in `configure.in' all modules and the binary were
318 linked against `libmysqlclient'. This issue is solved by this
321 2006-01-17, Version 3.6.0
322 * A config file has been added. This allows for loading only specific
324 * A `df' plugin has been added.
325 * A `mysql' plugin has been added.
326 * The `ping' plugin doesn't entirely give up hope when a socket error
327 occured, but will back of and increase the intervals between tries.
329 2006-01-21, Version 3.5.2
330 * Fixed yet another bug in the signal handling.. Stupid typo..
331 * Improved the ping plugin to not give up on socket errors (backport
334 2005-12-18, Version 3.5.1
335 * The PID-file is now deleted correctly when shutting down the daemon.
336 * SIGINT and SIGTERM are now handled correctly.
338 2005-12-16, Version 3.5.0 (Revision 326)
339 * A bug in the `load' module under Solaris has been fixed.
340 * The `users' module has been contributed by Sebastian Harl. It counts
341 currently logged in users.
342 * The CPU module now works under FreeBSD without the use of
343 `libstatgrab', however SMP support is missing.
344 * The default directories for the RRD files and the PID file now
345 depend on the compile time setting of `localstatedir'.
347 2005-11-15, Version 3.4.0 (Revision 236)
348 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
349 from gentoo's bugzilla for writing the patch.
350 * The build dependency for librrd has been removed. Binaries built
351 without librrd are client-only and will multicast their value as
352 with the `-c' argument.
353 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
354 * The newly introduced `-f' switch prevents daemon initialization
355 (forking, closing standard filehandles, etc.) Thanks to Alvaro
356 Barcellos for this patch.
358 2005-11-04, Version 3.3.0 (Revision 216)
359 * New modules have been added:
360 - `serial', for monitoring traffic on the serial interfaces
361 - `nfs', for graphing NFS procedure calls
362 - `tape', traffic from/to tape devices

373 2005-10-16, Version 3.1.0 (Revision 194)
374 * Added the `setsid' syscall to the startup code.
375 * Support for hddtemp has been added (thanks to Vincent Stehlé)
377 2005-09-30, Version 3.0.0 (Revision 184)
378 * The ability to send/receive data to/from the network (think
379 multicast) has been added.
380 * Modules have been split up into shared libraries can be loaded at
381 runtime. The biggest advantage is that the core program doesn't need
382 to be linked against an external library.
383 * A patch by George Kargiotakis has been applied: It fixes the sensors
384 behaviour then more than one sensor is being queried.
386 2005-09-16, Version 2.1.0 (Revision 172)
387 * A module for swap statistics has been added.
389 2005-09-09, Version 2.0.0 (Revision 135)
390 * Filenames can no longer be configured at program startup. The only
391 options as of this version are the directory and ping hosts.
392 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
393 Soft-IRQ statistics are added to `System'.
394 * Diskstats now collect read and write bytes, not sectors.
395 * Ping statistics can now be collected for more than one host. There
396 is no default any more: If no host is given no host will be pinged.
397 * A self-written patch for libping has been applied so it builds
400 2005-09-01, Version 1.8.1 (Revision 123)
401 * Much improved configure-script: libraries and features may now be
403 * More detailed warnings/error messages when RRD update failes.
405 2005-08-29, Version 1.8.0:
406 * Support for collecting disk statistics under Solaris.
408 2005-08-25, Version 1.7.0:
409 * Support for libstatgrab[1] for load, memory usage and network
410 traffic. CPU- and disk-usage are not (yet) supported, since
411 libstatgrab returns insufficient information. I will contact the
413 * Improved the CPU-initialization code for Solaris. Apparently CPUs
414 aren't neccessarily counted linear which is now handled correctly.
415 [1]: http://www.i-scream.org/libstatgrab/
417 2005-08-21, Version 1.6.0:
418 * Basic support for Solaris: System load and cpu-usage can be
419 collected unter Solaris, too. Other stats will follow later.
420 * Many fixes in the autoconf-script
421 * Collection/Museum scripts have been added unter contrib/museum
422 * collectd may now be started in unprivileged mode, though ping
423 statistics will not work.
425 2005-07-17, Version 1.5.1:
426 * Diskstats-RRDs now use major/minor for naming. Some systems have
427 weird strings as disk-names..
429 2005-07-17, Version 1.5:
430 * A new module, diskstats, has been added. It collects information
431 about the disks and partitions.
433 2005-07-11, Version 1.4.2:
434 * The meminfo mofule has been changed to work with more platforms
435 and/or kernel versions.
437 2005-07-10, Version 1.4.1: Correct traffic stats
438 * The traffic rrd-file is now created with DS-type `COUNTER' which I
439 forgot to correct when I changed that module.
441 2005-07-09, Version 1.4: More traffic stats
442 * Traffic is now collected for all interfaces that can be found
443 * Temperature-statistics are read from lm-sensors if available
445 2005-07-08, Version 1.3: CPU stats

448 2004-07-12, Version 1.2: Using syslog
449 * collectd is now using the syslog facility to report errors, warnings
451 * The default directory is now /var/db/collectd
453 2004-07-10, Version 1.1: Minor changes
454 * Nothing really usefull to say ;)
456 2004-07-09, Version 1.0: Initial Version
457 * The following modules are provided:
