1 2007-09-01, Version 4.1.0
2 * Build system: The build system has been changed to automatically
3 disable all plugins, which are missing dependencies. The dependency
4 checking has been removed from the plugins themselves to remove
6 * Flexible interval: The interval of collected data is not sent along
7 with the data itself over the network, so that the interval-settings
8 of server and clients no longer needs to match.
9 * netlink plugin: The new `netlink' plugin connects to the Linux
10 kernel using a netlink socket and uses it to query information about
11 interfaces, qdiscs and classes.
12 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
13 network devices, such as switches, routers, thermometers, rack
14 monitoring servers, etc. The collectd-snmp(5) manpage documents this
16 * unixsock plugin: Added the `LISTVAL' command.
17 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
18 of music played with xmms.
20 2007-08-26, Version 4.0.7
21 * documentation: Some typos have been fixed and some information has
23 * build system: Many fixes for detecting libraries in unusual places,
24 such as on RedHat systems. The affected libraries are `libcurl',
25 `libmysql', and `libupsclient'.
26 * network plugin: Allow the `Port' option to be specified as a number
27 (i. e. without quotes).
28 * nut plugin: A fix allows linking the nut plugin against
29 libupsclient, version >= 2.2.0.
31 2007-07-30, Version 4.0.6
32 * sensors plugin: Fix the ignorelist functionality: Only the `type
33 instance' was used to match against the list, but the documentation
34 told otherwise. This release fixes the code, so it complies with the
36 * syslog plugin: Call `openlog' right when the plugin is loaded, so
37 configuration messages will end up in the logging facility.
38 * conrtib/fedora: The contributed specfile for Fedora has been
41 2007-07-05, Version 4.0.5
42 * Portability: More fixes for OpenBSD have been included.
44 2007-06-24, Version 4.0.4
45 * cpu plugin: Fixed the Solaris code.
46 * dns plugin: Fixed a build issue for OpenBSD.
47 * interface plugin: Fixed the Solaris code.
48 * load plugin: Fixed the alternative `/proc' Linux code.
49 * memory plugin: Fixed the Solaris code.
50 * oconfig: Don't require `-lfl' anymore.
52 2007-06-19, Version 4.0.3
53 * cpu plugin: Fix the Darwin / Mac OS X code.

55 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
56 initialized correctly.
57 * configure: Added `--with-nan-emulation' to aid cross compilation.
59 2007-06-12, Version 4.0.2
60 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
61 they're given in numerically form.
63 2007-06-07, Version 4.0.1
64 * iptables plugin: A bug in the configuration routine has been fixed.
65 Setting a comment in the configfile will no longer cause a
68 2007-06-03, Version 4.0.0
69 * collectd: The plugin-infrastructure has been changed to allow for
70 more types of plugins, namely `write' and `log' plugins.
71 * collectd: The read-function has been changed to read many plugins in
72 parallel, using threads. Thus, plugins generally need to use
73 thread-safe functions from now on.
74 * collectd: The '-t' command line options allows to perform syntax tests
75 of the configuration file and exit immediately.
76 * csv plugin: The new `csv' plugin handles output to `comma separated
78 * rrdtool plugin: The new `rrdtool' plugin handles output to
79 RRD-files. Data can be cached to combine multiple updates into one
80 write to increase IO-performance.
81 * network plugin: The new `network' plugin handles IO via the network.
82 It implements a different, much more extensible protocol which can
83 combine many values in one packet, decreasing the number of UDP-
84 packets being sent. It can read from and send to the network and
85 with the appropriate configuration even forward packets to other
87 * unixsock plugin: The new `unixsock' plugin provides an interface to
88 communicate with the daemon while it is running. Right now the
89 commands `GETVAL' and `PUTVAL' are implemented, but more are to
91 * perl plugin: The new `perl' plugin allows you to write extensions
92 for collectd in the scripting-language Perl.
93 * logfile plugin: The new `logfile' plugin writes logmessages to files
95 * syslog plugin: The new `syslog' plugin sends logmessages to the
96 system's syslog daemon.
97 * entropy plugin: The new `entropy' plugin collects the amount of
98 entropy currently being available to the system.
99 * exec plugin: The new `exec' plugin forks child processes and reads
100 back values provided by the forked processes.
101 * iptables plugin: The new `iptables' plugin reads counters from
102 iptables rules. Thanks to Sjoerd van der Berg for contributing this
104 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
105 to Peter Holik for contributing this plugin.
106 * nut plugin: The new `nut' plugin connects the upsd of the `network
107 ups tools' and reads information about the connected UPS.
108 * apache plugin: Support for lighttpd's `BusyServers' (aka.
109 connections) field was added by Florent Monbillard.
110 * collectd-nagios: The new `collectd-nagios' binary queries values
111 from collectd, parses them and exits according to Nagios-standards.
112 * manpages: The manpages have been improved a lot.
114 2007-08-31, Version 3.11.6
115 * processes plugin: Fix a potential segmentation fault.
117 2007-05-29, Version 3.11.5
118 * configure: Added `AC_SYS_LARGEFILE' for LFS.
119 * ntpd plugin: Fix a potential buffer overflow.
120 * processes plugin: Fix a bug when run under Linux 2.4. All processes
121 were accounted as `zombies'.
123 2007-04-10, Version 3.11.4
124 * dns plugin: Change the order of includes to make the plugin compile
127 2007-03-30, Version 3.11.3
128 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
129 of the unused `COLLECT_KSTAT'.
131 2007-02-11, Version 3.11.2
132 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
133 NULL-pointer may have been passed to `printf' which causes a
134 segfault with some libcs.
136 2007-02-10, Version 3.11.1
137 * df plugin: Some wrong defines have been fixed so the plugin works
139 * dns plugin: The usage of a struct has been fixed to work with
141 * processes plugin: Some missing defines have been added so the plugin
142 compiles cleanly under FreeBSD and presumably other UNIXes.
144 2006-12-22, Version 3.11.0
145 * collectd: The new command line option `-P' makes it easier for
146 distributors to change the location of PID-files.
147 * collectd: The daemon shuts down faster now which makes it easier to
148 write init.d-scripts for it.
149 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
150 caused problems every now and then.
151 * df plugin: New config options allow to ignore certain mountpoints,
152 filesystem types or devices.
153 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
154 and interprets it. It collects traffic as well as qtype, opcode and
156 * email plugin: Sebastian Harl has contributed this plugin which
157 counts received mails in categories (e. g. ham, spam, virus), spam
158 score (as given by SpamAssassin) and check types.
159 * mbmon plugin: Flavio Stanchina has contributed this plugin which
160 uses `mbmon' to gather information from sensors on the motherboard.
161 * processes plugin: Collect detailed statistics for configured
162 processes, that's process and thread count, CPU usage, resident
163 segment size and pagefaults.
164 * multimeter plugin: Peter Holik contributed a new plugin which
166 * sensors plugin: Lubos Stanek has put much effort into improving this
167 plugin, including `extended naming', collection of voltage values
168 and the possibility to ignore certain values.
170 2006-12-21, Version 3.10.4
171 * Max Kellermann has identified a bug in the server routine: When
172 opening a socket fails the daemon will (re)try opening the socket in
173 an endless loop, ultimately leading to a `EMFILE' error.
175 2006-11-04, Version 3.10.3
176 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
177 ntpd's reply was sent in more than one packet, the buffer size was
178 calculated incorrectly, resulting in the reading of uninitialized or
181 2006-11-01, Version 3.10.2
182 * The sample config file has been improved.
183 * Errors in the manpages have been corrected.
184 * The ping-plugin now adds hosts during initialization, not during
185 startup. This speeds up starup when no network connectivity is
186 available. Also, the hosts are being added later when the network is
188 * Improved BSD-support for the df-plugin.
189 * Fixed syntax errors in the swap-plugin for Mac OS X.
190 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
192 * Don't disable the mysql-plugin if connecting to the database fails
193 during initialization. Instead, try again in increasing intervals.
195 2006-07-19, Version 3.10.1
196 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
197 the apcups cannot be reached, unconnected sockets will pile up and
198 eventually lead to `Too many open files' errors.
200 2006-07-09, Version 3.10.0
201 * The `disk' plugin has been ported to Darwin.
202 * The `battery' plugin should work on many Apple computers now.
203 * The `traffic' plugin can now ignore certain interfaces. Also,
204 statistics for sent/received packets and errors have been added.

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

244 * A plugin to monitor the Apache webserver has been added.
245 <http://httpd.apache.org/>
246 * A plugin to collect statistics about virtual servers using VServer.
247 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

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

298 2006-01-30, Version 3.7.0
299 * The `battery' plugin has been added. It collects information about
301 * The MySQL plugin has been improved: It now writes two more RRD
302 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
303 * The `cpufreq' plugin now reads another file since the file it did
304 read so far causes much overhead in the kernel. Also, you need root
305 to read the old file, but not to read the new one.
306 * The `hddtemp' plugin can now be configured to connect to another
307 address and/or port than localhost.
308 * The `df' plugin now prefers `statvfs' over `statfs'.
309 * The network code has been rewritten. collectd now supports unicast
310 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
311 be set in the configfile.
313 2006-01-24, Version 3.6.2
314 * Due to a bug in the configfile handling collectd wouldn't start in
315 client mode. This released fixes this.
317 2006-01-20, Version 3.6.1
318 * Due to a bug in `configure.in' all modules and the binary were
319 linked against `libmysqlclient'. This issue is solved by this
322 2006-01-17, Version 3.6.0
323 * A config file has been added. This allows for loading only specific
325 * A `df' plugin has been added.
326 * A `mysql' plugin has been added.
327 * The `ping' plugin doesn't entirely give up hope when a socket error
328 occured, but will back of and increase the intervals between tries.
330 2006-01-21, Version 3.5.2
331 * Fixed yet another bug in the signal handling.. Stupid typo..
332 * Improved the ping plugin to not give up on socket errors (backport
335 2005-12-18, Version 3.5.1
336 * The PID-file is now deleted correctly when shutting down the daemon.
337 * SIGINT and SIGTERM are now handled correctly.
339 2005-12-16, Version 3.5.0 (Revision 326)
340 * A bug in the `load' module under Solaris has been fixed.
341 * The `users' module has been contributed by Sebastian Harl. It counts
342 currently logged in users.
343 * The CPU module now works under FreeBSD without the use of
344 `libstatgrab', however SMP support is missing.
345 * The default directories for the RRD files and the PID file now
346 depend on the compile time setting of `localstatedir'.
348 2005-11-15, Version 3.4.0 (Revision 236)
349 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
350 from gentoo's bugzilla for writing the patch.
351 * The build dependency for librrd has been removed. Binaries built
352 without librrd are client-only and will multicast their value as
353 with the `-c' argument.
354 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
355 * The newly introduced `-f' switch prevents daemon initialization
356 (forking, closing standard filehandles, etc.) Thanks to Alvaro
357 Barcellos for this patch.
359 2005-11-04, Version 3.3.0 (Revision 216)
360 * New modules have been added:
361 - `serial', for monitoring traffic on the serial interfaces
362 - `nfs', for graphing NFS procedure calls
363 - `tape', traffic from/to tape devices
364 * The the memory.rrd now accepts more than 4Gig of memory.
366 2005-10-26, Version 3.2.0 (Revision 200)
367 * Support for graphing the processes has been added (thanks to Lyonel

374 2005-10-16, Version 3.1.0 (Revision 194)
375 * Added the `setsid' syscall to the startup code.
376 * Support for hddtemp has been added (thanks to Vincent Stehlé)
378 2005-09-30, Version 3.0.0 (Revision 184)
379 * The ability to send/receive data to/from the network (think
380 multicast) has been added.
381 * Modules have been split up into shared libraries can be loaded at
382 runtime. The biggest advantage is that the core program doesn't need
383 to be linked against an external library.
384 * A patch by George Kargiotakis has been applied: It fixes the sensors
385 behaviour then more than one sensor is being queried.
387 2005-09-16, Version 2.1.0 (Revision 172)
388 * A module for swap statistics has been added.
390 2005-09-09, Version 2.0.0 (Revision 135)
391 * Filenames can no longer be configured at program startup. The only
392 options as of this version are the directory and ping hosts.
393 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
394 Soft-IRQ statistics are added to `System'.
395 * Diskstats now collect read and write bytes, not sectors.
396 * Ping statistics can now be collected for more than one host. There
397 is no default any more: If no host is given no host will be pinged.
398 * A self-written patch for libping has been applied so it builds
401 2005-09-01, Version 1.8.1 (Revision 123)
402 * Much improved configure-script: libraries and features may now be
404 * More detailed warnings/error messages when RRD update failes.
406 2005-08-29, Version 1.8.0:
407 * Support for collecting disk statistics under Solaris.
409 2005-08-25, Version 1.7.0:
410 * Support for libstatgrab[1] for load, memory usage and network
411 traffic. CPU- and disk-usage are not (yet) supported, since
412 libstatgrab returns insufficient information. I will contact the
414 * Improved the CPU-initialization code for Solaris. Apparently CPUs
415 aren't neccessarily counted linear which is now handled correctly.
416 [1]: http://www.i-scream.org/libstatgrab/
418 2005-08-21, Version 1.6.0:
419 * Basic support for Solaris: System load and cpu-usage can be
420 collected unter Solaris, too. Other stats will follow later.
421 * Many fixes in the autoconf-script
422 * Collection/Museum scripts have been added unter contrib/museum
423 * collectd may now be started in unprivileged mode, though ping
424 statistics will not work.
426 2005-07-17, Version 1.5.1:
427 * Diskstats-RRDs now use major/minor for naming. Some systems have
428 weird strings as disk-names..
430 2005-07-17, Version 1.5:
431 * A new module, diskstats, has been added. It collects information
432 about the disks and partitions.
434 2005-07-11, Version 1.4.2:
435 * The meminfo mofule has been changed to work with more platforms
436 and/or kernel versions.
438 2005-07-10, Version 1.4.1: Correct traffic stats
439 * The traffic rrd-file is now created with DS-type `COUNTER' which I
440 forgot to correct when I changed that module.
442 2005-07-09, Version 1.4: More traffic stats
443 * Traffic is now collected for all interfaces that can be found
444 * Temperature-statistics are read from lm-sensors if available
446 2005-07-08, Version 1.3: CPU stats
447 * Collecting CPU statistics now
449 2004-07-12, Version 1.2: Using syslog
450 * collectd is now using the syslog facility to report errors, warnings

454 2004-07-10, Version 1.1: Minor changes
455 * Nothing really usefull to say ;)
457 2004-07-09, Version 1.0: Initial Version
458 * The following modules are provided:
