22 whatever the client thinks is `now'..
24 2007-09-01, Version 4.1.0
25 * Build system: The build system has been changed to automatically
26 disable all plugins, which are missing dependencies. The dependency
27 checking has been removed from the plugins themselves to remove
29 * Flexible interval: The interval of collected data is now sent along
30 with the data itself over the network, so that the interval-settings
31 of server and clients no longer needs to match.
32 * netlink plugin: The new `netlink' plugin connects to the Linux
33 kernel using a netlink socket and uses it to query information about
34 interfaces, qdiscs and classes.
35 * rrdtool plugin: The cache is now dumped to disk in an extra thread
36 to not block data collection.
37 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
38 network devices, such as switches, routers, thermometers, rack
39 monitoring servers, etc. The collectd-snmp(5) manpage documents this
41 * unixsock plugin: Added the `LISTVAL' command.

58 2007-08-26, Version 4.0.7
59 * documentation: Some typos have been fixed and some information has
61 * build system: Many fixes for detecting libraries in unusual places,
62 such as on RedHat systems. The affected libraries are `libcurl',
63 `libmysql', and `libupsclient'.
64 * network plugin: Allow the `Port' option to be specified as a number
65 (i. e. without quotes).
66 * nut plugin: A fix allows linking the nut plugin against
67 libupsclient, version >= 2.2.0.
68 * processes plugin: Fix a potential segmentation fault.
70 2007-07-30, Version 4.0.6
71 * sensors plugin: Fix the ignorelist functionality: Only the `type
72 instance' was used to match against the list, but the documentation
73 told otherwise. This release fixes the code, so it complies with the
75 * syslog plugin: Call `openlog' right when the plugin is loaded, so
76 configuration messages will end up in the logging facility.
77 * conrtib/fedora: The contributed specfile for Fedora has been
80 2007-07-05, Version 4.0.5
81 * Portability: More fixes for OpenBSD have been included.

104 Setting a comment in the configfile will no longer cause a
107 2007-06-03, Version 4.0.0
108 * collectd: The plugin-infrastructure has been changed to allow for
109 more types of plugins, namely `write' and `log' plugins.
110 * collectd: The read-function has been changed to read many plugins in
111 parallel, using threads. Thus, plugins generally need to use
112 thread-safe functions from now on.
113 * collectd: The '-t' command line options allows to perform syntax tests
114 of the configuration file and exit immediately.
115 * csv plugin: The new `csv' plugin handles output to `comma separated
117 * rrdtool plugin: The new `rrdtool' plugin handles output to
118 RRD-files. Data can be cached to combine multiple updates into one
119 write to increase IO-performance.
120 * network plugin: The new `network' plugin handles IO via the network.
121 It implements a different, much more extensible protocol which can
122 combine many values in one packet, decreasing the number of UDP-
123 packets being sent. It can read from and send to the network and
124 with the appropriate configuration even forward packets to other
126 * unixsock plugin: The new `unixsock' plugin provides an interface to
127 communicate with the daemon while it is running. Right now the
128 commands `GETVAL' and `PUTVAL' are implemented, but more are to
130 * perl plugin: The new `perl' plugin allows you to write extensions
131 for collectd in the scripting-language Perl.
132 * logfile plugin: The new `logfile' plugin writes logmessages to files
134 * syslog plugin: The new `syslog' plugin sends logmessages to the
135 system's syslog daemon.
136 * entropy plugin: The new `entropy' plugin collects the amount of
137 entropy currently being available to the system.
138 * exec plugin: The new `exec' plugin forks child processes and reads
139 back values provided by the forked processes.
140 * iptables plugin: The new `iptables' plugin reads counters from
141 iptables rules. Thanks to Sjoerd van der Berg for contributing this
143 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
144 to Peter Holik for contributing this plugin.
145 * nut plugin: The new `nut' plugin connects the upsd of the `network
146 ups tools' and reads information about the connected UPS.
147 * apache plugin: Support for lighttpd's `BusyServers' (aka.
148 connections) field was added by Florent Monbillard.
149 * collectd-nagios: The new `collectd-nagios' binary queries values
150 from collectd, parses them and exits according to Nagios-standards.
151 * manpages: The manpages have been improved a lot.
153 2007-08-31, Version 3.11.6
154 * processes plugin: Fix a potential segmentation fault.

157 * configure: Added `AC_SYS_LARGEFILE' for LFS.
158 * ntpd plugin: Fix a potential buffer overflow.
159 * processes plugin: Fix a bug when run under Linux 2.4. All processes
160 were accounted as `zombies'.
162 2007-04-10, Version 3.11.4
163 * dns plugin: Change the order of includes to make the plugin compile
166 2007-03-30, Version 3.11.3
167 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
168 of the unused `COLLECT_KSTAT'.
170 2007-02-11, Version 3.11.2
171 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
172 NULL-pointer may have been passed to `printf' which causes a
173 segfault with some libcs.
175 2007-02-10, Version 3.11.1
176 * df plugin: Some wrong defines have been fixed so the plugin works
178 * dns plugin: The usage of a struct has been fixed to work with
180 * processes plugin: Some missing defines have been added so the plugin
181 compiles cleanly under FreeBSD and presumably other UNIXes.
183 2006-12-22, Version 3.11.0
184 * collectd: The new command line option `-P' makes it easier for
185 distributors to change the location of PID-files.
186 * collectd: The daemon shuts down faster now which makes it easier to
187 write init.d-scripts for it.
188 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
189 caused problems every now and then.
190 * df plugin: New config options allow to ignore certain mountpoints,
191 filesystem types or devices.
192 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
193 and interprets it. It collects traffic as well as qtype, opcode and
195 * email plugin: Sebastian Harl has contributed this plugin which
196 counts received mails in categories (e. g. ham, spam, virus), spam
197 score (as given by SpamAssassin) and check types.
198 * mbmon plugin: Flavio Stanchina has contributed this plugin which
199 uses `mbmon' to gather information from sensors on the motherboard.
200 * processes plugin: Collect detailed statistics for configured
201 processes, that's process and thread count, CPU usage, resident
202 segment size and pagefaults.
203 * multimeter plugin: Peter Holik contributed a new plugin which
205 * sensors plugin: Lubos Stanek has put much effort into improving this
206 plugin, including `extended naming', collection of voltage values
207 and the possibility to ignore certain values.
209 2006-12-21, Version 3.10.4
210 * Max Kellermann has identified a bug in the server routine: When
211 opening a socket fails the daemon will (re)try opening the socket in
212 an endless loop, ultimately leading to a `EMFILE' error.
214 2006-11-04, Version 3.10.3
215 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
216 ntpd's reply was sent in more than one packet, the buffer size was
217 calculated incorrectly, resulting in the reading of uninitialized or
220 2006-11-01, Version 3.10.2
221 * The sample config file has been improved.
222 * Errors in the manpages have been corrected.
223 * The ping-plugin now adds hosts during initialization, not during
224 startup. This speeds up starup when no network connectivity is
225 available. Also, the hosts are being added later when the network is
227 * Improved BSD-support for the df-plugin.
228 * Fixed syntax errors in the swap-plugin for Mac OS X.
229 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
231 * Don't disable the mysql-plugin if connecting to the database fails
232 during initialization. Instead, try again in increasing intervals.
234 2006-07-19, Version 3.10.1
235 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
236 the apcups cannot be reached, unconnected sockets will pile up and
237 eventually lead to `Too many open files' errors.
239 2006-07-09, Version 3.10.0
240 * The `disk' plugin has been ported to Darwin.
241 * The `battery' plugin should work on many Apple computers now.
242 * The `traffic' plugin can now ignore certain interfaces. Also,
243 statistics for sent/received packets and errors have been added.
244 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
245 to Anthony Gialluca for contributing this plugin and providing me
246 with a test environment :)
247 * A plugin for moniroting an NTP instance and the local clock drift
250 2006-06-25, Version 3.9.4
251 * The Solaris code in the `swap' plugin has been changed to reflect
252 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
254 * The debugging system has been fixed to work with the Sun libc.
255 * When built without librrd the variable `operating_mode' could be
256 uninitialized. Thanks to David Elliot for reporting the bug.
258 2006-06-01, Version 3.9.3
259 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
260 operating systems also profit from the changes, but I wasn't able to
262 * Changed the build system to find the netinet-includes under FreeBSD
263 and therefore successfully build the `liboping' library there.
265 2006-05-09, Version 3.9.2
266 * Applied a patch to the `liboping' library. Due to a bug in the
267 sequence checking the `ping' plugin stopped working after
268 approximately 7.6 days.
270 2006-05-09, Version 3.8.5
271 * Applied a patch to the `liboping' library. Due to a bug in the
272 sequence checking the `ping' plugin stopped working after
273 approximately 7.6 days.
275 2006-04-21, Version 3.9.1
276 * Build issues with Solaris and possible other architectures have been
278 * Problems when building the `apache'-plugin without `libcurl' have

289 strength, link quality and noise ratio..
290 * A plugin for Apple hardware sensors has been added.
291 * An option to compile collectd with different `step' and `hearbeat'
292 settings has been added. The size of RRAs is no longer static but
293 calculated based on the settings for `step' and `width'.
294 * The `ping' plugin can now be configured to use a certain TTL.
295 * A plugin to monitor the hardware sensors of Apple computers has been
297 * The plugins `cpu', `memory', `processes' and `traffic' have been
298 ported to Mach/Darwin (Mac OS X).
299 * The `log mode' has been contributed by Christophe Kalt. It writes
300 the data into text files rather than RRD files.
302 2006-04-09, Version 3.8.4
303 * Applied patch by Vincent Stehlé which improves the disk-name
304 resolution in the `hddtemp' plugin for Linux systems.
306 2006-04-02, Version 3.8.3
307 * Applied a patch by James Byers: The MySQL plugin was not working
308 with MySQL 5.0.2 or later.
310 2006-03-14, Version 3.8.2
311 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
312 the GNU libc, because it points to `/etc/fstab' rather than
315 2006-03-13, Version 3.8.1
316 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
317 * Fixes in the debian `postinst' and `init.d' scripts.
319 2006-03-09, Version 3.8.0
320 * The `ping' plugin no longer uses `libping' but a self written
321 library named `liboping'. With this library it's possible to ping
322 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
324 2006-02-18, Version 3.7.2
325 * A simple bug in the `battery' plugin has been fixed. It should now
326 work with ACPI based batteries as well. Thankt to Sebastian for
328 * Fixing a bug that prevented collectd to be built without librrd.
329 Thanks to Werner Heuser for reporting it.
331 2006-02-04, Version 3.7.1
332 * The new network code has been improved to build with older versions

337 2006-01-30, Version 3.7.0
338 * The `battery' plugin has been added. It collects information about
340 * The MySQL plugin has been improved: It now writes two more RRD
341 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
342 * The `cpufreq' plugin now reads another file since the file it did
343 read so far causes much overhead in the kernel. Also, you need root
344 to read the old file, but not to read the new one.
345 * The `hddtemp' plugin can now be configured to connect to another
346 address and/or port than localhost.
347 * The `df' plugin now prefers `statvfs' over `statfs'.
348 * The network code has been rewritten. collectd now supports unicast
349 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
350 be set in the configfile.
352 2006-01-24, Version 3.6.2
353 * Due to a bug in the configfile handling collectd wouldn't start in
354 client mode. This released fixes this.
356 2006-01-20, Version 3.6.1
357 * Due to a bug in `configure.in' all modules and the binary were
358 linked against `libmysqlclient'. This issue is solved by this
361 2006-01-17, Version 3.6.0
362 * A config file has been added. This allows for loading only specific
364 * A `df' plugin has been added.
365 * A `mysql' plugin has been added.
366 * The `ping' plugin doesn't entirely give up hope when a socket error
367 occured, but will back of and increase the intervals between tries.
369 2006-01-21, Version 3.5.2
370 * Fixed yet another bug in the signal handling.. Stupid typo..
371 * Improved the ping plugin to not give up on socket errors (backport
374 2005-12-18, Version 3.5.1
375 * The PID-file is now deleted correctly when shutting down the daemon.
376 * SIGINT and SIGTERM are now handled correctly.
378 2005-12-16, Version 3.5.0 (Revision 326)
379 * A bug in the `load' module under Solaris has been fixed.
380 * The `users' module has been contributed by Sebastian Harl. It counts
381 currently logged in users.
382 * The CPU module now works under FreeBSD without the use of
383 `libstatgrab', however SMP support is missing.
384 * The default directories for the RRD files and the PID file now
385 depend on the compile time setting of `localstatedir'.
387 2005-11-15, Version 3.4.0 (Revision 236)
388 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
389 from gentoo's bugzilla for writing the patch.
390 * The build dependency for librrd has been removed. Binaries built
391 without librrd are client-only and will multicast their value as
392 with the `-c' argument.
393 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
394 * The newly introduced `-f' switch prevents daemon initialization
395 (forking, closing standard filehandles, etc.) Thanks to Alvaro
396 Barcellos for this patch.
398 2005-11-04, Version 3.3.0 (Revision 216)
399 * New modules have been added:
400 - `serial', for monitoring traffic on the serial interfaces
401 - `nfs', for graphing NFS procedure calls
402 - `tape', traffic from/to tape devices

413 2005-10-16, Version 3.1.0 (Revision 194)
414 * Added the `setsid' syscall to the startup code.
415 * Support for hddtemp has been added (thanks to Vincent Stehlé)
417 2005-09-30, Version 3.0.0 (Revision 184)
418 * The ability to send/receive data to/from the network (think
419 multicast) has been added.
420 * Modules have been split up into shared libraries can be loaded at
421 runtime. The biggest advantage is that the core program doesn't need
422 to be linked against an external library.
423 * A patch by George Kargiotakis has been applied: It fixes the sensors
424 behaviour then more than one sensor is being queried.
426 2005-09-16, Version 2.1.0 (Revision 172)
427 * A module for swap statistics has been added.
429 2005-09-09, Version 2.0.0 (Revision 135)
430 * Filenames can no longer be configured at program startup. The only
431 options as of this version are the directory and ping hosts.
432 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
433 Soft-IRQ statistics are added to `System'.
434 * Diskstats now collect read and write bytes, not sectors.
435 * Ping statistics can now be collected for more than one host. There
436 is no default any more: If no host is given no host will be pinged.
437 * A self-written patch for libping has been applied so it builds
440 2005-09-01, Version 1.8.1 (Revision 123)
441 * Much improved configure-script: libraries and features may now be
443 * More detailed warnings/error messages when RRD update failes.
445 2005-08-29, Version 1.8.0:
446 * Support for collecting disk statistics under Solaris.
448 2005-08-25, Version 1.7.0:
449 * Support for libstatgrab[1] for load, memory usage and network
450 traffic. CPU- and disk-usage are not (yet) supported, since
451 libstatgrab returns insufficient information. I will contact the
453 * Improved the CPU-initialization code for Solaris. Apparently CPUs
454 aren't neccessarily counted linear which is now handled correctly.
455 [1]: http://www.i-scream.org/libstatgrab/
457 2005-08-21, Version 1.6.0:
458 * Basic support for Solaris: System load and cpu-usage can be
459 collected unter Solaris, too. Other stats will follow later.
460 * Many fixes in the autoconf-script
461 * Collection/Museum scripts have been added unter contrib/museum
462 * collectd may now be started in unprivileged mode, though ping
463 statistics will not work.
465 2005-07-17, Version 1.5.1:
466 * Diskstats-RRDs now use major/minor for naming. Some systems have
467 weird strings as disk-names..
469 2005-07-17, Version 1.5:
470 * A new module, diskstats, has been added. It collects information
471 about the disks and partitions.
473 2005-07-11, Version 1.4.2:
474 * The meminfo mofule has been changed to work with more platforms
475 and/or kernel versions.
477 2005-07-10, Version 1.4.1: Correct traffic stats
478 * The traffic rrd-file is now created with DS-type `COUNTER' which I
479 forgot to correct when I changed that module.
481 2005-07-09, Version 1.4: More traffic stats
482 * Traffic is now collected for all interfaces that can be found
483 * Temperature-statistics are read from lm-sensors if available
485 2005-07-08, Version 1.3: CPU stats

493 2004-07-10, Version 1.1: Minor changes
494 * Nothing really usefull to say ;)
496 2004-07-09, Version 1.0: Initial Version
497 * The following modules are provided:
