1 2007-08-26, Version 4.0.7
2 * documentation: Some typos have been fixed and some information has
4 * build system: Many fixes for detecting libraries in unusual places,
5 such as on RedHat systems. The affected libraries are `libcurl',
6 `libmysql', and `libupsclient'.
7 * network plugin: Allow the `Port' option to be specified as a number
8 (i. e. without quotes).
9 * nut plugin: A fix allows linking the nut plugin against
10 libupsclient, version >= 2.2.0.
12 2007-07-30, Version 4.0.6
13 * sensors plugin: Fix the ignorelist functionality: Only the `type
14 instance' was used to match against the list, but the documentation
15 told otherwise. This release fixes the code, so it complies with the
17 * syslog plugin: Call `openlog' right when the plugin is loaded, so
18 configuration messages will end up in the logging facility.
19 * conrtib/fedora: The contributed specfile for Fedora has been
22 2007-07-05, Version 4.0.5
23 * Portability: More fixes for OpenBSD have been included.
25 2007-06-24, Version 4.0.4
26 * cpu plugin: Fixed the Solaris code.
27 * dns plugin: Fixed a build issue for OpenBSD.
28 * interface plugin: Fixed the Solaris code.
29 * load plugin: Fixed the alternative `/proc' Linux code.

31 * oconfig: Don't require `-lfl' anymore.
33 2007-06-19, Version 4.0.3
34 * cpu plugin: Fix the Darwin / Mac OS X code.
35 * ping plugin: Use the return value of `getpid', not its address.
36 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
37 initialized correctly.
38 * configure: Added `--with-nan-emulation' to aid cross compilation.
40 2007-06-12, Version 4.0.2
41 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
42 they're given in numerically form.
44 2007-06-07, Version 4.0.1
45 * iptables plugin: A bug in the configuration routine has been fixed.
46 Setting a comment in the configfile will no longer cause a
49 2007-06-03, Version 4.0.0
50 * collectd: The plugin-infrastructure has been changed to allow for
51 more types of plugins, namely `write' and `log' plugins.
52 * collectd: The read-function has been changed to read many plugins in
53 parallel, using threads. Thus, plugins generally need to use
54 thread-safe functions from now on.
55 * collectd: The '-t' command line options allows to perform syntax tests
56 of the configuration file and exit immediately.
57 * csv plugin: The new `csv' plugin handles output to `comma separated
59 * rrdtool plugin: The new `rrdtool' plugin handles output to
60 RRD-files. Data can be cached to combine multiple updates into one
61 write to increase IO-performance.
62 * network plugin: The new `network' plugin handles IO via the network.
63 It implements a different, much more extensible protocol which can
64 combine many values in one packet, decreasing the number of UDP-
65 packets being sent. It can read from and send to the network and
66 with the appropriate configuration even forward packets to other
68 * unixsock plugin: The new `unixsock' plugin provides an interface to
69 communicate with the daemon while it is running. Right now the
70 commands `GETVAL' and `PUTVAL' are implemented, but more are to
72 * perl plugin: The new `perl' plugin allows you to write extensions
73 for collectd in the scripting-language Perl.
74 * logfile plugin: The new `logfile' plugin writes logmessages to files
76 * syslog plugin: The new `syslog' plugin sends logmessages to the
77 system's syslog daemon.
78 * entropy plugin: The new `entropy' plugin collects the amount of
79 entropy currently being available to the system.
80 * exec plugin: The new `exec' plugin forks child processes and reads
81 back values provided by the forked processes.
82 * iptables plugin: The new `iptables' plugin reads counters from
83 iptables rules. Thanks to Sjoerd van der Berg for contributing this
85 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
86 to Peter Holik for contributing this plugin.
87 * nut plugin: The new `nut' plugin connects the upsd of the `network
88 ups tools' and reads information about the connected UPS.
89 * apache plugin: Support for lighttpd's `BusyServers' (aka.
90 connections) field was added by Florent Monbillard.
91 * collectd-nagios: The new `collectd-nagios' binary queries values
92 from collectd, parses them and exits according to Nagios-standards.
93 * manpages: The manpages have been improved a lot.
95 2007-08-31, Version 3.11.6
96 * processes plugin: Fix a potential segmentation fault.
98 2007-05-29, Version 3.11.5
99 * configure: Added `AC_SYS_LARGEFILE' for LFS.
100 * ntpd plugin: Fix a potential buffer overflow.
101 * processes plugin: Fix a bug when run under Linux 2.4. All processes
102 were accounted as `zombies'.
104 2007-04-10, Version 3.11.4
105 * dns plugin: Change the order of includes to make the plugin compile
108 2007-03-30, Version 3.11.3
109 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
110 of the unused `COLLECT_KSTAT'.
112 2007-02-11, Version 3.11.2
113 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
114 NULL-pointer may have been passed to `printf' which causes a
115 segfault with some libcs.
117 2007-02-10, Version 3.11.1
118 * df plugin: Some wrong defines have been fixed so the plugin works
120 * dns plugin: The usage of a struct has been fixed to work with
122 * processes plugin: Some missing defines have been added so the plugin
123 compiles cleanly under FreeBSD and presumably other UNIXes.
125 2006-12-22, Version 3.11.0
126 * collectd: The new command line option `-P' makes it easier for
127 distributors to change the location of PID-files.
128 * collectd: The daemon shuts down faster now which makes it easier to
129 write init.d-scripts for it.
130 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
131 caused problems every now and then.
132 * df plugin: New config options allow to ignore certain mountpoints,
133 filesystem types or devices.
134 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
135 and interprets it. It collects traffic as well as qtype, opcode and
137 * email plugin: Sebastian Harl has contributed this plugin which
138 counts received mails in categories (e. g. ham, spam, virus), spam
139 score (as given by SpamAssassin) and check types.
140 * mbmon plugin: Flavio Stanchina has contributed this plugin which
141 uses `mbmon' to gather information from sensors on the motherboard.
142 * processes plugin: Collect detailed statistics for configured
143 processes, that's process and thread count, CPU usage, resident
144 segment size and pagefaults.
145 * multimeter plugin: Peter Holik contributed a new plugin which
147 * sensors plugin: Lubos Stanek has put much effort into improving this
148 plugin, including `extended naming', collection of voltage values
149 and the possibility to ignore certain values.
151 2006-12-21, Version 3.10.4
152 * Max Kellermann has identified a bug in the server routine: When
153 opening a socket fails the daemon will (re)try opening the socket in
154 an endless loop, ultimately leading to a `EMFILE' error.
156 2006-11-04, Version 3.10.3
157 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
158 ntpd's reply was sent in more than one packet, the buffer size was
159 calculated incorrectly, resulting in the reading of uninitialized or
162 2006-11-01, Version 3.10.2
163 * The sample config file has been improved.
164 * Errors in the manpages have been corrected.
165 * The ping-plugin now adds hosts during initialization, not during
166 startup. This speeds up starup when no network connectivity is
167 available. Also, the hosts are being added later when the network is
169 * Improved BSD-support for the df-plugin.
170 * Fixed syntax errors in the swap-plugin for Mac OS X.
171 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
173 * Don't disable the mysql-plugin if connecting to the database fails
174 during initialization. Instead, try again in increasing intervals.
176 2006-07-19, Version 3.10.1
177 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
178 the apcups cannot be reached, unconnected sockets will pile up and
179 eventually lead to `Too many open files' errors.
181 2006-07-09, Version 3.10.0
182 * The `disk' plugin has been ported to Darwin.
183 * The `battery' plugin should work on many Apple computers now.
184 * The `traffic' plugin can now ignore certain interfaces. Also,
185 statistics for sent/received packets and errors have been added.
186 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
187 to Anthony Gialluca for contributing this plugin and providing me
188 with a test environment :)
189 * A plugin for moniroting an NTP instance and the local clock drift
192 2006-06-25, Version 3.9.4
193 * The Solaris code in the `swap' plugin has been changed to reflect
194 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
196 * The debugging system has been fixed to work with the Sun libc.
197 * When built without librrd the variable `operating_mode' could be
198 uninitialized. Thanks to David Elliot for reporting the bug.
200 2006-06-01, Version 3.9.3
201 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
202 operating systems also profit from the changes, but I wasn't able to
204 * Changed the build system to find the netinet-includes under FreeBSD
205 and therefore successfully build the `liboping' library there.
207 2006-05-09, Version 3.9.2
208 * Applied a patch to the `liboping' library. Due to a bug in the
209 sequence checking the `ping' plugin stopped working after
210 approximately 7.6 days.
212 2006-05-09, Version 3.8.5
213 * Applied a patch to the `liboping' library. Due to a bug in the
214 sequence checking the `ping' plugin stopped working after
215 approximately 7.6 days.
217 2006-04-21, Version 3.9.1
218 * Build issues with Solaris and possible other architectures have been
220 * Problems when building the `apache'-plugin without `libcurl' have
222 * A bug in the `ping' plugin has been fixed. Sorry folks.
224 2006-04-02, Version 3.9.0
225 * A plugin to monitor the Apache webserver has been added.
226 <http://httpd.apache.org/>
227 * A plugin to collect statistics about virtual servers using VServer.
228 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

231 strength, link quality and noise ratio..
232 * A plugin for Apple hardware sensors has been added.
233 * An option to compile collectd with different `step' and `hearbeat'
234 settings has been added. The size of RRAs is no longer static but
235 calculated based on the settings for `step' and `width'.
236 * The `ping' plugin can now be configured to use a certain TTL.
237 * A plugin to monitor the hardware sensors of Apple computers has been
239 * The plugins `cpu', `memory', `processes' and `traffic' have been
240 ported to Mach/Darwin (Mac OS X).
241 * The `log mode' has been contributed by Christophe Kalt. It writes
242 the data into text files rather than RRD files.
244 2006-04-09, Version 3.8.4
245 * Applied patch by Vincent Stehlé which improves the disk-name
246 resolution in the `hddtemp' plugin for Linux systems.
248 2006-04-02, Version 3.8.3
249 * Applied a patch by James Byers: The MySQL plugin was not working
250 with MySQL 5.0.2 or later.
252 2006-03-14, Version 3.8.2
253 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
254 the GNU libc, because it points to `/etc/fstab' rather than
257 2006-03-13, Version 3.8.1
258 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
259 * Fixes in the debian `postinst' and `init.d' scripts.
261 2006-03-09, Version 3.8.0
262 * The `ping' plugin no longer uses `libping' but a self written
263 library named `liboping'. With this library it's possible to ping
264 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
266 2006-02-18, Version 3.7.2
267 * A simple bug in the `battery' plugin has been fixed. It should now
268 work with ACPI based batteries as well. Thankt to Sebastian for
270 * Fixing a bug that prevented collectd to be built without librrd.
271 Thanks to Werner Heuser for reporting it.
273 2006-02-04, Version 3.7.1
274 * The new network code has been improved to build with older versions

279 2006-01-30, Version 3.7.0
280 * The `battery' plugin has been added. It collects information about
282 * The MySQL plugin has been improved: It now writes two more RRD
283 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
284 * The `cpufreq' plugin now reads another file since the file it did
285 read so far causes much overhead in the kernel. Also, you need root
286 to read the old file, but not to read the new one.
287 * The `hddtemp' plugin can now be configured to connect to another
288 address and/or port than localhost.
289 * The `df' plugin now prefers `statvfs' over `statfs'.
290 * The network code has been rewritten. collectd now supports unicast
291 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
292 be set in the configfile.
294 2006-01-24, Version 3.6.2
295 * Due to a bug in the configfile handling collectd wouldn't start in
296 client mode. This released fixes this.
298 2006-01-20, Version 3.6.1
299 * Due to a bug in `configure.in' all modules and the binary were
300 linked against `libmysqlclient'. This issue is solved by this
303 2006-01-17, Version 3.6.0
304 * A config file has been added. This allows for loading only specific
306 * A `df' plugin has been added.
307 * A `mysql' plugin has been added.
308 * The `ping' plugin doesn't entirely give up hope when a socket error
309 occured, but will back of and increase the intervals between tries.
311 2006-01-21, Version 3.5.2
312 * Fixed yet another bug in the signal handling.. Stupid typo..
313 * Improved the ping plugin to not give up on socket errors (backport
316 2005-12-18, Version 3.5.1
317 * The PID-file is now deleted correctly when shutting down the daemon.
318 * SIGINT and SIGTERM are now handled correctly.
320 2005-12-16, Version 3.5.0 (Revision 326)
321 * A bug in the `load' module under Solaris has been fixed.
322 * The `users' module has been contributed by Sebastian Harl. It counts
323 currently logged in users.
324 * The CPU module now works under FreeBSD without the use of
325 `libstatgrab', however SMP support is missing.
326 * The default directories for the RRD files and the PID file now
327 depend on the compile time setting of `localstatedir'.
329 2005-11-15, Version 3.4.0 (Revision 236)
330 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
331 from gentoo's bugzilla for writing the patch.
332 * The build dependency for librrd has been removed. Binaries built
333 without librrd are client-only and will multicast their value as
334 with the `-c' argument.
335 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
336 * The newly introduced `-f' switch prevents daemon initialization
337 (forking, closing standard filehandles, etc.) Thanks to Alvaro
338 Barcellos for this patch.
340 2005-11-04, Version 3.3.0 (Revision 216)
341 * New modules have been added:
342 - `serial', for monitoring traffic on the serial interfaces
343 - `nfs', for graphing NFS procedure calls
344 - `tape', traffic from/to tape devices
345 * The the memory.rrd now accepts more than 4Gig of memory.
347 2005-10-26, Version 3.2.0 (Revision 200)
348 * Support for graphing the processes has been added (thanks to Lyonel

353 * Problems with the spec file have been fixed.
355 2005-10-16, Version 3.1.0 (Revision 194)
356 * Added the `setsid' syscall to the startup code.
357 * Support for hddtemp has been added (thanks to Vincent Stehlé)
359 2005-09-30, Version 3.0.0 (Revision 184)
360 * The ability to send/receive data to/from the network (think
361 multicast) has been added.
362 * Modules have been split up into shared libraries can be loaded at
363 runtime. The biggest advantage is that the core program doesn't need
364 to be linked against an external library.
365 * A patch by George Kargiotakis has been applied: It fixes the sensors
366 behaviour then more than one sensor is being queried.
368 2005-09-16, Version 2.1.0 (Revision 172)
369 * A module for swap statistics has been added.
371 2005-09-09, Version 2.0.0 (Revision 135)
372 * Filenames can no longer be configured at program startup. The only
373 options as of this version are the directory and ping hosts.
374 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
375 Soft-IRQ statistics are added to `System'.
376 * Diskstats now collect read and write bytes, not sectors.
377 * Ping statistics can now be collected for more than one host. There
378 is no default any more: If no host is given no host will be pinged.
379 * A self-written patch for libping has been applied so it builds
382 2005-09-01, Version 1.8.1 (Revision 123)
383 * Much improved configure-script: libraries and features may now be
385 * More detailed warnings/error messages when RRD update failes.
387 2005-08-29, Version 1.8.0:
388 * Support for collecting disk statistics under Solaris.
390 2005-08-25, Version 1.7.0:
391 * Support for libstatgrab[1] for load, memory usage and network
392 traffic. CPU- and disk-usage are not (yet) supported, since
393 libstatgrab returns insufficient information. I will contact the
395 * Improved the CPU-initialization code for Solaris. Apparently CPUs
396 aren't neccessarily counted linear which is now handled correctly.
397 [1]: http://www.i-scream.org/libstatgrab/
399 2005-08-21, Version 1.6.0:
400 * Basic support for Solaris: System load and cpu-usage can be
401 collected unter Solaris, too. Other stats will follow later.
402 * Many fixes in the autoconf-script
403 * Collection/Museum scripts have been added unter contrib/museum
404 * collectd may now be started in unprivileged mode, though ping
405 statistics will not work.
407 2005-07-17, Version 1.5.1:
408 * Diskstats-RRDs now use major/minor for naming. Some systems have
409 weird strings as disk-names..
411 2005-07-17, Version 1.5:
412 * A new module, diskstats, has been added. It collects information
413 about the disks and partitions.
415 2005-07-11, Version 1.4.2:
416 * The meminfo mofule has been changed to work with more platforms
417 and/or kernel versions.
419 2005-07-10, Version 1.4.1: Correct traffic stats
420 * The traffic rrd-file is now created with DS-type `COUNTER' which I
421 forgot to correct when I changed that module.
423 2005-07-09, Version 1.4: More traffic stats
424 * Traffic is now collected for all interfaces that can be found
425 * Temperature-statistics are read from lm-sensors if available
427 2005-07-08, Version 1.3: CPU stats
428 * Collecting CPU statistics now
430 2004-07-12, Version 1.2: Using syslog
431 * collectd is now using the syslog facility to report errors, warnings

435 2004-07-10, Version 1.1: Minor changes
436 * Nothing really usefull to say ;)
438 2004-07-09, Version 1.0: Initial Version
439 * The following modules are provided:
