3 * collectd: The documentation has been fixed in numerous places.
4 * exec plugin: Setting the group under which to run a program has been
7 2007-09-01, Version 4.1.0
8 * Build system: The build system has been changed to automatically
9 disable all plugins, which are missing dependencies. The dependency
10 checking has been removed from the plugins themselves to remove
12 * Flexible interval: The interval of collected data is now sent along
13 with the data itself over the network, so that the interval-settings
14 of server and clients no longer needs to match.
15 * netlink plugin: The new `netlink' plugin connects to the Linux
16 kernel using a netlink socket and uses it to query information about
17 interfaces, qdiscs and classes.
18 * rrdtool plugin: The cache is now dumped to disk in an extra thread
19 to not block data collection.
20 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
21 network devices, such as switches, routers, thermometers, rack
22 monitoring servers, etc. The collectd-snmp(5) manpage documents this
24 * unixsock plugin: Added the `LISTVAL' command.
25 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
26 of music played with xmms.
28 2007-09-10, Version 4.0.8
29 * collectd: The `sstrerror' function was improved to work correctly
30 with the broken GNU version of `strerror_r'.
32 2007-08-26, Version 4.0.7
33 * documentation: Some typos have been fixed and some information has
35 * build system: Many fixes for detecting libraries in unusual places,
36 such as on RedHat systems. The affected libraries are `libcurl',
37 `libmysql', and `libupsclient'.
38 * network plugin: Allow the `Port' option to be specified as a number
39 (i. e. without quotes).
40 * nut plugin: A fix allows linking the nut plugin against
41 libupsclient, version >= 2.2.0.
42 * processes plugin: Fix a potential segmentation fault.
44 2007-07-30, Version 4.0.6
45 * sensors plugin: Fix the ignorelist functionality: Only the `type
46 instance' was used to match against the list, but the documentation
47 told otherwise. This release fixes the code, so it complies with the
49 * syslog plugin: Call `openlog' right when the plugin is loaded, so
50 configuration messages will end up in the logging facility.
51 * conrtib/fedora: The contributed specfile for Fedora has been
54 2007-07-05, Version 4.0.5
55 * Portability: More fixes for OpenBSD have been included.

74 they're given in numerically form.
76 2007-06-07, Version 4.0.1
77 * iptables plugin: A bug in the configuration routine has been fixed.
78 Setting a comment in the configfile will no longer cause a
81 2007-06-03, Version 4.0.0
82 * collectd: The plugin-infrastructure has been changed to allow for
83 more types of plugins, namely `write' and `log' plugins.
84 * collectd: The read-function has been changed to read many plugins in
85 parallel, using threads. Thus, plugins generally need to use
86 thread-safe functions from now on.
87 * collectd: The '-t' command line options allows to perform syntax tests
88 of the configuration file and exit immediately.
89 * csv plugin: The new `csv' plugin handles output to `comma separated
91 * rrdtool plugin: The new `rrdtool' plugin handles output to
92 RRD-files. Data can be cached to combine multiple updates into one
93 write to increase IO-performance.
94 * network plugin: The new `network' plugin handles IO via the network.
95 It implements a different, much more extensible protocol which can
96 combine many values in one packet, decreasing the number of UDP-
97 packets being sent. It can read from and send to the network and
98 with the appropriate configuration even forward packets to other
100 * unixsock plugin: The new `unixsock' plugin provides an interface to
101 communicate with the daemon while it is running. Right now the
102 commands `GETVAL' and `PUTVAL' are implemented, but more are to
104 * perl plugin: The new `perl' plugin allows you to write extensions
105 for collectd in the scripting-language Perl.
106 * logfile plugin: The new `logfile' plugin writes logmessages to files
108 * syslog plugin: The new `syslog' plugin sends logmessages to the
109 system's syslog daemon.
110 * entropy plugin: The new `entropy' plugin collects the amount of
111 entropy currently being available to the system.
112 * exec plugin: The new `exec' plugin forks child processes and reads
113 back values provided by the forked processes.
114 * iptables plugin: The new `iptables' plugin reads counters from
115 iptables rules. Thanks to Sjoerd van der Berg for contributing this
117 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
118 to Peter Holik for contributing this plugin.
119 * nut plugin: The new `nut' plugin connects the upsd of the `network
120 ups tools' and reads information about the connected UPS.
121 * apache plugin: Support for lighttpd's `BusyServers' (aka.
122 connections) field was added by Florent Monbillard.
123 * collectd-nagios: The new `collectd-nagios' binary queries values
124 from collectd, parses them and exits according to Nagios-standards.
125 * manpages: The manpages have been improved a lot.
127 2007-08-31, Version 3.11.6
128 * processes plugin: Fix a potential segmentation fault.
130 2007-05-29, Version 3.11.5
131 * configure: Added `AC_SYS_LARGEFILE' for LFS.
132 * ntpd plugin: Fix a potential buffer overflow.
133 * processes plugin: Fix a bug when run under Linux 2.4. All processes
134 were accounted as `zombies'.
136 2007-04-10, Version 3.11.4
137 * dns plugin: Change the order of includes to make the plugin compile
140 2007-03-30, Version 3.11.3
141 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
142 of the unused `COLLECT_KSTAT'.
144 2007-02-11, Version 3.11.2
145 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
146 NULL-pointer may have been passed to `printf' which causes a
147 segfault with some libcs.
149 2007-02-10, Version 3.11.1
150 * df plugin: Some wrong defines have been fixed so the plugin works
152 * dns plugin: The usage of a struct has been fixed to work with
154 * processes plugin: Some missing defines have been added so the plugin
155 compiles cleanly under FreeBSD and presumably other UNIXes.
157 2006-12-22, Version 3.11.0
158 * collectd: The new command line option `-P' makes it easier for
159 distributors to change the location of PID-files.
160 * collectd: The daemon shuts down faster now which makes it easier to
161 write init.d-scripts for it.
162 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
163 caused problems every now and then.
164 * df plugin: New config options allow to ignore certain mountpoints,
165 filesystem types or devices.
166 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
167 and interprets it. It collects traffic as well as qtype, opcode and
169 * email plugin: Sebastian Harl has contributed this plugin which
170 counts received mails in categories (e. g. ham, spam, virus), spam
171 score (as given by SpamAssassin) and check types.
172 * mbmon plugin: Flavio Stanchina has contributed this plugin which
173 uses `mbmon' to gather information from sensors on the motherboard.
174 * processes plugin: Collect detailed statistics for configured
175 processes, that's process and thread count, CPU usage, resident
176 segment size and pagefaults.
177 * multimeter plugin: Peter Holik contributed a new plugin which
179 * sensors plugin: Lubos Stanek has put much effort into improving this
180 plugin, including `extended naming', collection of voltage values
181 and the possibility to ignore certain values.
183 2006-12-21, Version 3.10.4
184 * Max Kellermann has identified a bug in the server routine: When
185 opening a socket fails the daemon will (re)try opening the socket in
186 an endless loop, ultimately leading to a `EMFILE' error.
188 2006-11-04, Version 3.10.3
189 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
190 ntpd's reply was sent in more than one packet, the buffer size was
191 calculated incorrectly, resulting in the reading of uninitialized or
194 2006-11-01, Version 3.10.2
195 * The sample config file has been improved.
196 * Errors in the manpages have been corrected.
197 * The ping-plugin now adds hosts during initialization, not during
198 startup. This speeds up starup when no network connectivity is
199 available. Also, the hosts are being added later when the network is
201 * Improved BSD-support for the df-plugin.
202 * Fixed syntax errors in the swap-plugin for Mac OS X.
203 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
205 * Don't disable the mysql-plugin if connecting to the database fails
206 during initialization. Instead, try again in increasing intervals.
208 2006-07-19, Version 3.10.1
209 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
210 the apcups cannot be reached, unconnected sockets will pile up and
211 eventually lead to `Too many open files' errors.
213 2006-07-09, Version 3.10.0
214 * The `disk' plugin has been ported to Darwin.
215 * The `battery' plugin should work on many Apple computers now.
216 * The `traffic' plugin can now ignore certain interfaces. Also,
217 statistics for sent/received packets and errors have been added.

219 to Anthony Gialluca for contributing this plugin and providing me
220 with a test environment :)
221 * A plugin for moniroting an NTP instance and the local clock drift
224 2006-06-25, Version 3.9.4
225 * The Solaris code in the `swap' plugin has been changed to reflect
226 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
228 * The debugging system has been fixed to work with the Sun libc.
229 * When built without librrd the variable `operating_mode' could be
230 uninitialized. Thanks to David Elliot for reporting the bug.
232 2006-06-01, Version 3.9.3
233 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
234 operating systems also profit from the changes, but I wasn't able to
236 * Changed the build system to find the netinet-includes under FreeBSD
237 and therefore successfully build the `liboping' library there.
239 2006-05-09, Version 3.9.2
240 * Applied a patch to the `liboping' library. Due to a bug in the
241 sequence checking the `ping' plugin stopped working after
242 approximately 7.6 days.
244 2006-05-09, Version 3.8.5
245 * Applied a patch to the `liboping' library. Due to a bug in the
246 sequence checking the `ping' plugin stopped working after
247 approximately 7.6 days.
249 2006-04-21, Version 3.9.1
250 * Build issues with Solaris and possible other architectures have been
252 * Problems when building the `apache'-plugin without `libcurl' have

263 strength, link quality and noise ratio..
264 * A plugin for Apple hardware sensors has been added.
265 * An option to compile collectd with different `step' and `hearbeat'
266 settings has been added. The size of RRAs is no longer static but
267 calculated based on the settings for `step' and `width'.
268 * The `ping' plugin can now be configured to use a certain TTL.
269 * A plugin to monitor the hardware sensors of Apple computers has been
271 * The plugins `cpu', `memory', `processes' and `traffic' have been
272 ported to Mach/Darwin (Mac OS X).
273 * The `log mode' has been contributed by Christophe Kalt. It writes
274 the data into text files rather than RRD files.
276 2006-04-09, Version 3.8.4
277 * Applied patch by Vincent Stehlé which improves the disk-name
278 resolution in the `hddtemp' plugin for Linux systems.
280 2006-04-02, Version 3.8.3
281 * Applied a patch by James Byers: The MySQL plugin was not working
282 with MySQL 5.0.2 or later.
284 2006-03-14, Version 3.8.2
285 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
286 the GNU libc, because it points to `/etc/fstab' rather than
289 2006-03-13, Version 3.8.1
290 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
291 * Fixes in the debian `postinst' and `init.d' scripts.
293 2006-03-09, Version 3.8.0
294 * The `ping' plugin no longer uses `libping' but a self written
295 library named `liboping'. With this library it's possible to ping
296 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
298 2006-02-18, Version 3.7.2
299 * A simple bug in the `battery' plugin has been fixed. It should now
300 work with ACPI based batteries as well. Thankt to Sebastian for
302 * Fixing a bug that prevented collectd to be built without librrd.
303 Thanks to Werner Heuser for reporting it.
305 2006-02-04, Version 3.7.1
306 * The new network code has been improved to build with older versions

311 2006-01-30, Version 3.7.0
312 * The `battery' plugin has been added. It collects information about
314 * The MySQL plugin has been improved: It now writes two more RRD
315 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
316 * The `cpufreq' plugin now reads another file since the file it did
317 read so far causes much overhead in the kernel. Also, you need root
318 to read the old file, but not to read the new one.
319 * The `hddtemp' plugin can now be configured to connect to another
320 address and/or port than localhost.
321 * The `df' plugin now prefers `statvfs' over `statfs'.
322 * The network code has been rewritten. collectd now supports unicast
323 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
324 be set in the configfile.
326 2006-01-24, Version 3.6.2
327 * Due to a bug in the configfile handling collectd wouldn't start in
328 client mode. This released fixes this.
330 2006-01-20, Version 3.6.1
331 * Due to a bug in `configure.in' all modules and the binary were
332 linked against `libmysqlclient'. This issue is solved by this
335 2006-01-17, Version 3.6.0
336 * A config file has been added. This allows for loading only specific
338 * A `df' plugin has been added.
339 * A `mysql' plugin has been added.
340 * The `ping' plugin doesn't entirely give up hope when a socket error
341 occured, but will back of and increase the intervals between tries.
343 2006-01-21, Version 3.5.2
344 * Fixed yet another bug in the signal handling.. Stupid typo..
345 * Improved the ping plugin to not give up on socket errors (backport
348 2005-12-18, Version 3.5.1
349 * The PID-file is now deleted correctly when shutting down the daemon.
350 * SIGINT and SIGTERM are now handled correctly.
352 2005-12-16, Version 3.5.0 (Revision 326)
353 * A bug in the `load' module under Solaris has been fixed.
354 * The `users' module has been contributed by Sebastian Harl. It counts
355 currently logged in users.
356 * The CPU module now works under FreeBSD without the use of
357 `libstatgrab', however SMP support is missing.
358 * The default directories for the RRD files and the PID file now
359 depend on the compile time setting of `localstatedir'.
361 2005-11-15, Version 3.4.0 (Revision 236)
362 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
363 from gentoo's bugzilla for writing the patch.
364 * The build dependency for librrd has been removed. Binaries built
365 without librrd are client-only and will multicast their value as
366 with the `-c' argument.
367 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
368 * The newly introduced `-f' switch prevents daemon initialization
369 (forking, closing standard filehandles, etc.) Thanks to Alvaro
370 Barcellos for this patch.
372 2005-11-04, Version 3.3.0 (Revision 216)
373 * New modules have been added:
374 - `serial', for monitoring traffic on the serial interfaces
375 - `nfs', for graphing NFS procedure calls
376 - `tape', traffic from/to tape devices
377 * The the memory.rrd now accepts more than 4Gig of memory.
379 2005-10-26, Version 3.2.0 (Revision 200)
380 * Support for graphing the processes has been added (thanks to Lyonel

387 2005-10-16, Version 3.1.0 (Revision 194)
388 * Added the `setsid' syscall to the startup code.
389 * Support for hddtemp has been added (thanks to Vincent Stehlé)
391 2005-09-30, Version 3.0.0 (Revision 184)
392 * The ability to send/receive data to/from the network (think
393 multicast) has been added.
394 * Modules have been split up into shared libraries can be loaded at
395 runtime. The biggest advantage is that the core program doesn't need
396 to be linked against an external library.
397 * A patch by George Kargiotakis has been applied: It fixes the sensors
398 behaviour then more than one sensor is being queried.
400 2005-09-16, Version 2.1.0 (Revision 172)
401 * A module for swap statistics has been added.
403 2005-09-09, Version 2.0.0 (Revision 135)
404 * Filenames can no longer be configured at program startup. The only
405 options as of this version are the directory and ping hosts.
406 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
407 Soft-IRQ statistics are added to `System'.
408 * Diskstats now collect read and write bytes, not sectors.
409 * Ping statistics can now be collected for more than one host. There
410 is no default any more: If no host is given no host will be pinged.
411 * A self-written patch for libping has been applied so it builds
414 2005-09-01, Version 1.8.1 (Revision 123)
415 * Much improved configure-script: libraries and features may now be
417 * More detailed warnings/error messages when RRD update failes.
419 2005-08-29, Version 1.8.0:
420 * Support for collecting disk statistics under Solaris.
422 2005-08-25, Version 1.7.0:
423 * Support for libstatgrab[1] for load, memory usage and network
424 traffic. CPU- and disk-usage are not (yet) supported, since
425 libstatgrab returns insufficient information. I will contact the
427 * Improved the CPU-initialization code for Solaris. Apparently CPUs
428 aren't neccessarily counted linear which is now handled correctly.
429 [1]: http://www.i-scream.org/libstatgrab/
431 2005-08-21, Version 1.6.0:
432 * Basic support for Solaris: System load and cpu-usage can be
433 collected unter Solaris, too. Other stats will follow later.
434 * Many fixes in the autoconf-script
435 * Collection/Museum scripts have been added unter contrib/museum
436 * collectd may now be started in unprivileged mode, though ping
437 statistics will not work.
439 2005-07-17, Version 1.5.1:
440 * Diskstats-RRDs now use major/minor for naming. Some systems have
441 weird strings as disk-names..
443 2005-07-17, Version 1.5:
444 * A new module, diskstats, has been added. It collects information
445 about the disks and partitions.
447 2005-07-11, Version 1.4.2:
448 * The meminfo mofule has been changed to work with more platforms
449 and/or kernel versions.
451 2005-07-10, Version 1.4.1: Correct traffic stats
452 * The traffic rrd-file is now created with DS-type `COUNTER' which I
453 forgot to correct when I changed that module.
455 2005-07-09, Version 1.4: More traffic stats
456 * Traffic is now collected for all interfaces that can be found
457 * Temperature-statistics are read from lm-sensors if available
459 2005-07-08, Version 1.3: CPU stats

467 2004-07-10, Version 1.1: Minor changes
468 * Nothing really usefull to say ;)
470 2004-07-09, Version 1.0: Initial Version
471 * The following modules are provided:
