18 whatever the client thinks is `now'..
20 2007-09-01, Version 4.1.0
21 * Build system: The build system has been changed to automatically
22 disable all plugins, which are missing dependencies. The dependency
23 checking has been removed from the plugins themselves to remove
25 * Flexible interval: The interval of collected data is now sent along
26 with the data itself over the network, so that the interval-settings
27 of server and clients no longer needs to match.
28 * netlink plugin: The new `netlink' plugin connects to the Linux
29 kernel using a netlink socket and uses it to query information about
30 interfaces, qdiscs and classes.
31 * rrdtool plugin: The cache is now dumped to disk in an extra thread
32 to not block data collection.
33 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
34 network devices, such as switches, routers, thermometers, rack

54 2007-08-26, Version 4.0.7
55 * documentation: Some typos have been fixed and some information has
57 * build system: Many fixes for detecting libraries in unusual places,
58 such as on RedHat systems. The affected libraries are `libcurl',
59 `libmysql', and `libupsclient'.
60 * network plugin: Allow the `Port' option to be specified as a number
61 (i. e. without quotes).
62 * nut plugin: A fix allows linking the nut plugin against
63 libupsclient, version >= 2.2.0.
64 * processes plugin: Fix a potential segmentation fault.
66 2007-07-30, Version 4.0.6
67 * sensors plugin: Fix the ignorelist functionality: Only the `type
68 instance' was used to match against the list, but the documentation
69 told otherwise. This release fixes the code, so it complies with the
71 * syslog plugin: Call `openlog' right when the plugin is loaded, so
72 configuration messages will end up in the logging facility.
73 * conrtib/fedora: The contributed specfile for Fedora has been
76 2007-07-05, Version 4.0.5
77 * Portability: More fixes for OpenBSD have been included.

100 Setting a comment in the configfile will no longer cause a
103 2007-06-03, Version 4.0.0
104 * collectd: The plugin-infrastructure has been changed to allow for
105 more types of plugins, namely `write' and `log' plugins.
106 * collectd: The read-function has been changed to read many plugins in
107 parallel, using threads. Thus, plugins generally need to use
108 thread-safe functions from now on.
109 * collectd: The '-t' command line options allows to perform syntax tests
110 of the configuration file and exit immediately.
111 * csv plugin: The new `csv' plugin handles output to `comma separated
113 * rrdtool plugin: The new `rrdtool' plugin handles output to
114 RRD-files. Data can be cached to combine multiple updates into one
115 write to increase IO-performance.
116 * network plugin: The new `network' plugin handles IO via the network.
117 It implements a different, much more extensible protocol which can
118 combine many values in one packet, decreasing the number of UDP-
119 packets being sent. It can read from and send to the network and
120 with the appropriate configuration even forward packets to other
122 * unixsock plugin: The new `unixsock' plugin provides an interface to
123 communicate with the daemon while it is running. Right now the
124 commands `GETVAL' and `PUTVAL' are implemented, but more are to
126 * perl plugin: The new `perl' plugin allows you to write extensions
127 for collectd in the scripting-language Perl.
128 * logfile plugin: The new `logfile' plugin writes logmessages to files
130 * syslog plugin: The new `syslog' plugin sends logmessages to the
131 system's syslog daemon.
132 * entropy plugin: The new `entropy' plugin collects the amount of
133 entropy currently being available to the system.
134 * exec plugin: The new `exec' plugin forks child processes and reads
135 back values provided by the forked processes.

137 iptables rules. Thanks to Sjoerd van der Berg for contributing this
139 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
140 to Peter Holik for contributing this plugin.
141 * nut plugin: The new `nut' plugin connects the upsd of the `network
142 ups tools' and reads information about the connected UPS.
143 * apache plugin: Support for lighttpd's `BusyServers' (aka.
144 connections) field was added by Florent Monbillard.
145 * collectd-nagios: The new `collectd-nagios' binary queries values
146 from collectd, parses them and exits according to Nagios-standards.
147 * manpages: The manpages have been improved a lot.
149 2007-08-31, Version 3.11.6
150 * processes plugin: Fix a potential segmentation fault.

153 * configure: Added `AC_SYS_LARGEFILE' for LFS.
154 * ntpd plugin: Fix a potential buffer overflow.
155 * processes plugin: Fix a bug when run under Linux 2.4. All processes
156 were accounted as `zombies'.
158 2007-04-10, Version 3.11.4
159 * dns plugin: Change the order of includes to make the plugin compile
162 2007-03-30, Version 3.11.3
163 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
164 of the unused `COLLECT_KSTAT'.
166 2007-02-11, Version 3.11.2
167 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
168 NULL-pointer may have been passed to `printf' which causes a
169 segfault with some libcs.
171 2007-02-10, Version 3.11.1
172 * df plugin: Some wrong defines have been fixed so the plugin works
174 * dns plugin: The usage of a struct has been fixed to work with
176 * processes plugin: Some missing defines have been added so the plugin
177 compiles cleanly under FreeBSD and presumably other UNIXes.
179 2006-12-22, Version 3.11.0
180 * collectd: The new command line option `-P' makes it easier for
181 distributors to change the location of PID-files.
182 * collectd: The daemon shuts down faster now which makes it easier to
183 write init.d-scripts for it.
184 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
185 caused problems every now and then.
186 * df plugin: New config options allow to ignore certain mountpoints,
187 filesystem types or devices.
188 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
189 and interprets it. It collects traffic as well as qtype, opcode and
191 * email plugin: Sebastian Harl has contributed this plugin which
192 counts received mails in categories (e. g. ham, spam, virus), spam
193 score (as given by SpamAssassin) and check types.
194 * mbmon plugin: Flavio Stanchina has contributed this plugin which
195 uses `mbmon' to gather information from sensors on the motherboard.
196 * processes plugin: Collect detailed statistics for configured
197 processes, that's process and thread count, CPU usage, resident
198 segment size and pagefaults.
199 * multimeter plugin: Peter Holik contributed a new plugin which
201 * sensors plugin: Lubos Stanek has put much effort into improving this
202 plugin, including `extended naming', collection of voltage values
203 and the possibility to ignore certain values.
205 2006-12-21, Version 3.10.4
206 * Max Kellermann has identified a bug in the server routine: When
207 opening a socket fails the daemon will (re)try opening the socket in
208 an endless loop, ultimately leading to a `EMFILE' error.
210 2006-11-04, Version 3.10.3
211 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
212 ntpd's reply was sent in more than one packet, the buffer size was
213 calculated incorrectly, resulting in the reading of uninitialized or
216 2006-11-01, Version 3.10.2
217 * The sample config file has been improved.
218 * Errors in the manpages have been corrected.
219 * The ping-plugin now adds hosts during initialization, not during
220 startup. This speeds up starup when no network connectivity is
221 available. Also, the hosts are being added later when the network is
223 * Improved BSD-support for the df-plugin.
224 * Fixed syntax errors in the swap-plugin for Mac OS X.
225 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
227 * Don't disable the mysql-plugin if connecting to the database fails
228 during initialization. Instead, try again in increasing intervals.
230 2006-07-19, Version 3.10.1
231 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
232 the apcups cannot be reached, unconnected sockets will pile up and
233 eventually lead to `Too many open files' errors.
235 2006-07-09, Version 3.10.0
236 * The `disk' plugin has been ported to Darwin.
237 * The `battery' plugin should work on many Apple computers now.
238 * The `traffic' plugin can now ignore certain interfaces. Also,
239 statistics for sent/received packets and errors have been added.

241 to Anthony Gialluca for contributing this plugin and providing me
242 with a test environment :)
243 * A plugin for moniroting an NTP instance and the local clock drift
246 2006-06-25, Version 3.9.4
247 * The Solaris code in the `swap' plugin has been changed to reflect
248 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
250 * The debugging system has been fixed to work with the Sun libc.
251 * When built without librrd the variable `operating_mode' could be
252 uninitialized. Thanks to David Elliot for reporting the bug.
254 2006-06-01, Version 3.9.3
255 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
256 operating systems also profit from the changes, but I wasn't able to
258 * Changed the build system to find the netinet-includes under FreeBSD
259 and therefore successfully build the `liboping' library there.
261 2006-05-09, Version 3.9.2
262 * Applied a patch to the `liboping' library. Due to a bug in the
263 sequence checking the `ping' plugin stopped working after
264 approximately 7.6 days.
266 2006-05-09, Version 3.8.5
267 * Applied a patch to the `liboping' library. Due to a bug in the
268 sequence checking the `ping' plugin stopped working after
269 approximately 7.6 days.
271 2006-04-21, Version 3.9.1
272 * Build issues with Solaris and possible other architectures have been
274 * Problems when building the `apache'-plugin without `libcurl' have

285 strength, link quality and noise ratio..
286 * A plugin for Apple hardware sensors has been added.
287 * An option to compile collectd with different `step' and `hearbeat'
288 settings has been added. The size of RRAs is no longer static but
289 calculated based on the settings for `step' and `width'.
290 * The `ping' plugin can now be configured to use a certain TTL.
291 * A plugin to monitor the hardware sensors of Apple computers has been
293 * The plugins `cpu', `memory', `processes' and `traffic' have been
294 ported to Mach/Darwin (Mac OS X).
295 * The `log mode' has been contributed by Christophe Kalt. It writes
296 the data into text files rather than RRD files.
298 2006-04-09, Version 3.8.4
299 * Applied patch by Vincent Stehlé which improves the disk-name
300 resolution in the `hddtemp' plugin for Linux systems.
302 2006-04-02, Version 3.8.3
303 * Applied a patch by James Byers: The MySQL plugin was not working
304 with MySQL 5.0.2 or later.
306 2006-03-14, Version 3.8.2
307 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
308 the GNU libc, because it points to `/etc/fstab' rather than
311 2006-03-13, Version 3.8.1
312 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
313 * Fixes in the debian `postinst' and `init.d' scripts.
315 2006-03-09, Version 3.8.0
316 * The `ping' plugin no longer uses `libping' but a self written
317 library named `liboping'. With this library it's possible to ping
318 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
320 2006-02-18, Version 3.7.2
321 * A simple bug in the `battery' plugin has been fixed. It should now
322 work with ACPI based batteries as well. Thankt to Sebastian for
324 * Fixing a bug that prevented collectd to be built without librrd.
325 Thanks to Werner Heuser for reporting it.
327 2006-02-04, Version 3.7.1
328 * The new network code has been improved to build with older versions

333 2006-01-30, Version 3.7.0
334 * The `battery' plugin has been added. It collects information about
336 * The MySQL plugin has been improved: It now writes two more RRD
337 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
338 * The `cpufreq' plugin now reads another file since the file it did
339 read so far causes much overhead in the kernel. Also, you need root
340 to read the old file, but not to read the new one.
341 * The `hddtemp' plugin can now be configured to connect to another
342 address and/or port than localhost.
343 * The `df' plugin now prefers `statvfs' over `statfs'.
344 * The network code has been rewritten. collectd now supports unicast
345 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
346 be set in the configfile.
348 2006-01-24, Version 3.6.2
349 * Due to a bug in the configfile handling collectd wouldn't start in
350 client mode. This released fixes this.
352 2006-01-20, Version 3.6.1
353 * Due to a bug in `configure.in' all modules and the binary were
354 linked against `libmysqlclient'. This issue is solved by this
357 2006-01-17, Version 3.6.0
358 * A config file has been added. This allows for loading only specific
360 * A `df' plugin has been added.
361 * A `mysql' plugin has been added.
362 * The `ping' plugin doesn't entirely give up hope when a socket error
363 occured, but will back of and increase the intervals between tries.
365 2006-01-21, Version 3.5.2
366 * Fixed yet another bug in the signal handling.. Stupid typo..
367 * Improved the ping plugin to not give up on socket errors (backport
370 2005-12-18, Version 3.5.1
371 * The PID-file is now deleted correctly when shutting down the daemon.
372 * SIGINT and SIGTERM are now handled correctly.
374 2005-12-16, Version 3.5.0 (Revision 326)
375 * A bug in the `load' module under Solaris has been fixed.
376 * The `users' module has been contributed by Sebastian Harl. It counts
377 currently logged in users.
378 * The CPU module now works under FreeBSD without the use of
379 `libstatgrab', however SMP support is missing.
380 * The default directories for the RRD files and the PID file now
381 depend on the compile time setting of `localstatedir'.
383 2005-11-15, Version 3.4.0 (Revision 236)
384 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
385 from gentoo's bugzilla for writing the patch.
386 * The build dependency for librrd has been removed. Binaries built
387 without librrd are client-only and will multicast their value as
388 with the `-c' argument.
389 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
390 * The newly introduced `-f' switch prevents daemon initialization
391 (forking, closing standard filehandles, etc.) Thanks to Alvaro
392 Barcellos for this patch.
394 2005-11-04, Version 3.3.0 (Revision 216)
395 * New modules have been added:
396 - `serial', for monitoring traffic on the serial interfaces
397 - `nfs', for graphing NFS procedure calls
398 - `tape', traffic from/to tape devices

409 2005-10-16, Version 3.1.0 (Revision 194)
410 * Added the `setsid' syscall to the startup code.
411 * Support for hddtemp has been added (thanks to Vincent Stehlé)
413 2005-09-30, Version 3.0.0 (Revision 184)
414 * The ability to send/receive data to/from the network (think
415 multicast) has been added.
416 * Modules have been split up into shared libraries can be loaded at
417 runtime. The biggest advantage is that the core program doesn't need
418 to be linked against an external library.
419 * A patch by George Kargiotakis has been applied: It fixes the sensors
420 behaviour then more than one sensor is being queried.
422 2005-09-16, Version 2.1.0 (Revision 172)
423 * A module for swap statistics has been added.
425 2005-09-09, Version 2.0.0 (Revision 135)
426 * Filenames can no longer be configured at program startup. The only
427 options as of this version are the directory and ping hosts.
428 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
429 Soft-IRQ statistics are added to `System'.
430 * Diskstats now collect read and write bytes, not sectors.
431 * Ping statistics can now be collected for more than one host. There
432 is no default any more: If no host is given no host will be pinged.
433 * A self-written patch for libping has been applied so it builds
436 2005-09-01, Version 1.8.1 (Revision 123)
437 * Much improved configure-script: libraries and features may now be
439 * More detailed warnings/error messages when RRD update failes.
441 2005-08-29, Version 1.8.0:
442 * Support for collecting disk statistics under Solaris.
444 2005-08-25, Version 1.7.0:
445 * Support for libstatgrab[1] for load, memory usage and network
446 traffic. CPU- and disk-usage are not (yet) supported, since
447 libstatgrab returns insufficient information. I will contact the
449 * Improved the CPU-initialization code for Solaris. Apparently CPUs
450 aren't neccessarily counted linear which is now handled correctly.
451 [1]: http://www.i-scream.org/libstatgrab/
453 2005-08-21, Version 1.6.0:
454 * Basic support for Solaris: System load and cpu-usage can be
455 collected unter Solaris, too. Other stats will follow later.
456 * Many fixes in the autoconf-script
457 * Collection/Museum scripts have been added unter contrib/museum
458 * collectd may now be started in unprivileged mode, though ping
459 statistics will not work.
461 2005-07-17, Version 1.5.1:
462 * Diskstats-RRDs now use major/minor for naming. Some systems have
463 weird strings as disk-names..
465 2005-07-17, Version 1.5:
466 * A new module, diskstats, has been added. It collects information
467 about the disks and partitions.
469 2005-07-11, Version 1.4.2:
470 * The meminfo mofule has been changed to work with more platforms
471 and/or kernel versions.
473 2005-07-10, Version 1.4.1: Correct traffic stats
474 * The traffic rrd-file is now created with DS-type `COUNTER' which I
475 forgot to correct when I changed that module.
477 2005-07-09, Version 1.4: More traffic stats
478 * Traffic is now collected for all interfaces that can be found
479 * Temperature-statistics are read from lm-sensors if available
