1 2007-09-10, Version 4.0.8
2 * collectd: The `sstrerror' function was improved to work correctly
3 with the broken GNU version of `strerror_r'.
5 2007-08-26, Version 4.0.7
6 * documentation: Some typos have been fixed and some information has
8 * build system: Many fixes for detecting libraries in unusual places,
9 such as on RedHat systems. The affected libraries are `libcurl',
10 `libmysql', and `libupsclient'.
11 * network plugin: Allow the `Port' option to be specified as a number
12 (i. e. without quotes).
13 * nut plugin: A fix allows linking the nut plugin against
14 libupsclient, version >= 2.2.0.
16 2007-07-30, Version 4.0.6
17 * sensors plugin: Fix the ignorelist functionality: Only the `type
18 instance' was used to match against the list, but the documentation
19 told otherwise. This release fixes the code, so it complies with the
21 * syslog plugin: Call `openlog' right when the plugin is loaded, so
22 configuration messages will end up in the logging facility.
23 * conrtib/fedora: The contributed specfile for Fedora has been
26 2007-07-05, Version 4.0.5
27 * Portability: More fixes for OpenBSD have been included.
29 2007-06-24, Version 4.0.4

42 * configure: Added `--with-nan-emulation' to aid cross compilation.
44 2007-06-12, Version 4.0.2
45 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
46 they're given in numerically form.
48 2007-06-07, Version 4.0.1
49 * iptables plugin: A bug in the configuration routine has been fixed.
50 Setting a comment in the configfile will no longer cause a
53 2007-06-03, Version 4.0.0
54 * collectd: The plugin-infrastructure has been changed to allow for
55 more types of plugins, namely `write' and `log' plugins.
56 * collectd: The read-function has been changed to read many plugins in
57 parallel, using threads. Thus, plugins generally need to use
58 thread-safe functions from now on.
59 * collectd: The '-t' command line options allows to perform syntax tests
60 of the configuration file and exit immediately.
61 * csv plugin: The new `csv' plugin handles output to `comma separated
63 * rrdtool plugin: The new `rrdtool' plugin handles output to
64 RRD-files. Data can be cached to combine multiple updates into one
65 write to increase IO-performance.
66 * network plugin: The new `network' plugin handles IO via the network.
67 It implements a different, much more extensible protocol which can
68 combine many values in one packet, decreasing the number of UDP-
69 packets being sent. It can read from and send to the network and
70 with the appropriate configuration even forward packets to other
72 * unixsock plugin: The new `unixsock' plugin provides an interface to
73 communicate with the daemon while it is running. Right now the
74 commands `GETVAL' and `PUTVAL' are implemented, but more are to
76 * perl plugin: The new `perl' plugin allows you to write extensions
77 for collectd in the scripting-language Perl.
78 * logfile plugin: The new `logfile' plugin writes logmessages to files
80 * syslog plugin: The new `syslog' plugin sends logmessages to the
81 system's syslog daemon.
82 * entropy plugin: The new `entropy' plugin collects the amount of
83 entropy currently being available to the system.
84 * exec plugin: The new `exec' plugin forks child processes and reads
85 back values provided by the forked processes.
86 * iptables plugin: The new `iptables' plugin reads counters from
87 iptables rules. Thanks to Sjoerd van der Berg for contributing this
89 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
90 to Peter Holik for contributing this plugin.
91 * nut plugin: The new `nut' plugin connects the upsd of the `network
92 ups tools' and reads information about the connected UPS.
93 * apache plugin: Support for lighttpd's `BusyServers' (aka.
94 connections) field was added by Florent Monbillard.
95 * collectd-nagios: The new `collectd-nagios' binary queries values
96 from collectd, parses them and exits according to Nagios-standards.
97 * manpages: The manpages have been improved a lot.
99 2007-08-31, Version 3.11.6
100 * processes plugin: Fix a potential segmentation fault.
102 2007-05-29, Version 3.11.5
103 * configure: Added `AC_SYS_LARGEFILE' for LFS.
104 * ntpd plugin: Fix a potential buffer overflow.
105 * processes plugin: Fix a bug when run under Linux 2.4. All processes
106 were accounted as `zombies'.
108 2007-04-10, Version 3.11.4
109 * dns plugin: Change the order of includes to make the plugin compile
112 2007-03-30, Version 3.11.3
113 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
114 of the unused `COLLECT_KSTAT'.
116 2007-02-11, Version 3.11.2
117 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
118 NULL-pointer may have been passed to `printf' which causes a
119 segfault with some libcs.
121 2007-02-10, Version 3.11.1
122 * df plugin: Some wrong defines have been fixed so the plugin works
124 * dns plugin: The usage of a struct has been fixed to work with
126 * processes plugin: Some missing defines have been added so the plugin
127 compiles cleanly under FreeBSD and presumably other UNIXes.
129 2006-12-22, Version 3.11.0
130 * collectd: The new command line option `-P' makes it easier for
131 distributors to change the location of PID-files.
132 * collectd: The daemon shuts down faster now which makes it easier to
133 write init.d-scripts for it.
134 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
135 caused problems every now and then.
136 * df plugin: New config options allow to ignore certain mountpoints,
137 filesystem types or devices.
138 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
139 and interprets it. It collects traffic as well as qtype, opcode and
141 * email plugin: Sebastian Harl has contributed this plugin which
142 counts received mails in categories (e. g. ham, spam, virus), spam
143 score (as given by SpamAssassin) and check types.
144 * mbmon plugin: Flavio Stanchina has contributed this plugin which
145 uses `mbmon' to gather information from sensors on the motherboard.
146 * processes plugin: Collect detailed statistics for configured
147 processes, that's process and thread count, CPU usage, resident
148 segment size and pagefaults.
149 * multimeter plugin: Peter Holik contributed a new plugin which
151 * sensors plugin: Lubos Stanek has put much effort into improving this
152 plugin, including `extended naming', collection of voltage values
153 and the possibility to ignore certain values.
155 2006-12-21, Version 3.10.4
156 * Max Kellermann has identified a bug in the server routine: When
157 opening a socket fails the daemon will (re)try opening the socket in
158 an endless loop, ultimately leading to a `EMFILE' error.
160 2006-11-04, Version 3.10.3
161 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
162 ntpd's reply was sent in more than one packet, the buffer size was
163 calculated incorrectly, resulting in the reading of uninitialized or
166 2006-11-01, Version 3.10.2
167 * The sample config file has been improved.
168 * Errors in the manpages have been corrected.
169 * The ping-plugin now adds hosts during initialization, not during
170 startup. This speeds up starup when no network connectivity is
171 available. Also, the hosts are being added later when the network is
173 * Improved BSD-support for the df-plugin.
174 * Fixed syntax errors in the swap-plugin for Mac OS X.
175 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
177 * Don't disable the mysql-plugin if connecting to the database fails
178 during initialization. Instead, try again in increasing intervals.
180 2006-07-19, Version 3.10.1
181 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
182 the apcups cannot be reached, unconnected sockets will pile up and
183 eventually lead to `Too many open files' errors.
185 2006-07-09, Version 3.10.0
186 * The `disk' plugin has been ported to Darwin.
187 * The `battery' plugin should work on many Apple computers now.
188 * The `traffic' plugin can now ignore certain interfaces. Also,
189 statistics for sent/received packets and errors have been added.
190 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
191 to Anthony Gialluca for contributing this plugin and providing me
192 with a test environment :)
193 * A plugin for moniroting an NTP instance and the local clock drift
196 2006-06-25, Version 3.9.4
197 * The Solaris code in the `swap' plugin has been changed to reflect
198 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
200 * The debugging system has been fixed to work with the Sun libc.
201 * When built without librrd the variable `operating_mode' could be
202 uninitialized. Thanks to David Elliot for reporting the bug.
204 2006-06-01, Version 3.9.3
205 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
206 operating systems also profit from the changes, but I wasn't able to
208 * Changed the build system to find the netinet-includes under FreeBSD
209 and therefore successfully build the `liboping' library there.
211 2006-05-09, Version 3.9.2
212 * Applied a patch to the `liboping' library. Due to a bug in the
213 sequence checking the `ping' plugin stopped working after
214 approximately 7.6 days.
216 2006-05-09, Version 3.8.5
217 * Applied a patch to the `liboping' library. Due to a bug in the
218 sequence checking the `ping' plugin stopped working after
219 approximately 7.6 days.
221 2006-04-21, Version 3.9.1
222 * Build issues with Solaris and possible other architectures have been
224 * Problems when building the `apache'-plugin without `libcurl' have

235 strength, link quality and noise ratio..
236 * A plugin for Apple hardware sensors has been added.
237 * An option to compile collectd with different `step' and `hearbeat'
238 settings has been added. The size of RRAs is no longer static but
239 calculated based on the settings for `step' and `width'.
240 * The `ping' plugin can now be configured to use a certain TTL.
241 * A plugin to monitor the hardware sensors of Apple computers has been
243 * The plugins `cpu', `memory', `processes' and `traffic' have been
244 ported to Mach/Darwin (Mac OS X).
245 * The `log mode' has been contributed by Christophe Kalt. It writes
246 the data into text files rather than RRD files.
248 2006-04-09, Version 3.8.4
249 * Applied patch by Vincent Stehlé which improves the disk-name
250 resolution in the `hddtemp' plugin for Linux systems.
252 2006-04-02, Version 3.8.3
253 * Applied a patch by James Byers: The MySQL plugin was not working
254 with MySQL 5.0.2 or later.
256 2006-03-14, Version 3.8.2
257 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
258 the GNU libc, because it points to `/etc/fstab' rather than
261 2006-03-13, Version 3.8.1
262 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
263 * Fixes in the debian `postinst' and `init.d' scripts.
265 2006-03-09, Version 3.8.0
266 * The `ping' plugin no longer uses `libping' but a self written
267 library named `liboping'. With this library it's possible to ping
268 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
270 2006-02-18, Version 3.7.2
271 * A simple bug in the `battery' plugin has been fixed. It should now
272 work with ACPI based batteries as well. Thankt to Sebastian for
274 * Fixing a bug that prevented collectd to be built without librrd.
275 Thanks to Werner Heuser for reporting it.
277 2006-02-04, Version 3.7.1
278 * The new network code has been improved to build with older versions

283 2006-01-30, Version 3.7.0
284 * The `battery' plugin has been added. It collects information about
286 * The MySQL plugin has been improved: It now writes two more RRD
287 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
288 * The `cpufreq' plugin now reads another file since the file it did
289 read so far causes much overhead in the kernel. Also, you need root
290 to read the old file, but not to read the new one.
291 * The `hddtemp' plugin can now be configured to connect to another
292 address and/or port than localhost.
293 * The `df' plugin now prefers `statvfs' over `statfs'.
294 * The network code has been rewritten. collectd now supports unicast
295 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
296 be set in the configfile.
298 2006-01-24, Version 3.6.2
299 * Due to a bug in the configfile handling collectd wouldn't start in
300 client mode. This released fixes this.
302 2006-01-20, Version 3.6.1
303 * Due to a bug in `configure.in' all modules and the binary were
304 linked against `libmysqlclient'. This issue is solved by this
307 2006-01-17, Version 3.6.0
308 * A config file has been added. This allows for loading only specific
310 * A `df' plugin has been added.
311 * A `mysql' plugin has been added.
312 * The `ping' plugin doesn't entirely give up hope when a socket error
313 occured, but will back of and increase the intervals between tries.
315 2006-01-21, Version 3.5.2
316 * Fixed yet another bug in the signal handling.. Stupid typo..
317 * Improved the ping plugin to not give up on socket errors (backport
320 2005-12-18, Version 3.5.1
321 * The PID-file is now deleted correctly when shutting down the daemon.
322 * SIGINT and SIGTERM are now handled correctly.
324 2005-12-16, Version 3.5.0 (Revision 326)
325 * A bug in the `load' module under Solaris has been fixed.
326 * The `users' module has been contributed by Sebastian Harl. It counts
327 currently logged in users.
328 * The CPU module now works under FreeBSD without the use of
329 `libstatgrab', however SMP support is missing.
330 * The default directories for the RRD files and the PID file now
331 depend on the compile time setting of `localstatedir'.
333 2005-11-15, Version 3.4.0 (Revision 236)
334 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
335 from gentoo's bugzilla for writing the patch.
336 * The build dependency for librrd has been removed. Binaries built
337 without librrd are client-only and will multicast their value as
338 with the `-c' argument.
339 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
340 * The newly introduced `-f' switch prevents daemon initialization
341 (forking, closing standard filehandles, etc.) Thanks to Alvaro
342 Barcellos for this patch.
344 2005-11-04, Version 3.3.0 (Revision 216)
345 * New modules have been added:
346 - `serial', for monitoring traffic on the serial interfaces
347 - `nfs', for graphing NFS procedure calls
348 - `tape', traffic from/to tape devices
349 * The the memory.rrd now accepts more than 4Gig of memory.
351 2005-10-26, Version 3.2.0 (Revision 200)
352 * Support for graphing the processes has been added (thanks to Lyonel

359 2005-10-16, Version 3.1.0 (Revision 194)
360 * Added the `setsid' syscall to the startup code.
361 * Support for hddtemp has been added (thanks to Vincent Stehlé)
363 2005-09-30, Version 3.0.0 (Revision 184)
364 * The ability to send/receive data to/from the network (think
365 multicast) has been added.
366 * Modules have been split up into shared libraries can be loaded at
367 runtime. The biggest advantage is that the core program doesn't need
368 to be linked against an external library.
369 * A patch by George Kargiotakis has been applied: It fixes the sensors
370 behaviour then more than one sensor is being queried.
372 2005-09-16, Version 2.1.0 (Revision 172)
373 * A module for swap statistics has been added.
375 2005-09-09, Version 2.0.0 (Revision 135)
376 * Filenames can no longer be configured at program startup. The only
377 options as of this version are the directory and ping hosts.
378 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
379 Soft-IRQ statistics are added to `System'.
380 * Diskstats now collect read and write bytes, not sectors.
381 * Ping statistics can now be collected for more than one host. There
382 is no default any more: If no host is given no host will be pinged.
383 * A self-written patch for libping has been applied so it builds
386 2005-09-01, Version 1.8.1 (Revision 123)
387 * Much improved configure-script: libraries and features may now be
389 * More detailed warnings/error messages when RRD update failes.
391 2005-08-29, Version 1.8.0:
392 * Support for collecting disk statistics under Solaris.
394 2005-08-25, Version 1.7.0:
395 * Support for libstatgrab[1] for load, memory usage and network
396 traffic. CPU- and disk-usage are not (yet) supported, since
397 libstatgrab returns insufficient information. I will contact the
399 * Improved the CPU-initialization code for Solaris. Apparently CPUs
400 aren't neccessarily counted linear which is now handled correctly.
401 [1]: http://www.i-scream.org/libstatgrab/
403 2005-08-21, Version 1.6.0:
404 * Basic support for Solaris: System load and cpu-usage can be
405 collected unter Solaris, too. Other stats will follow later.
406 * Many fixes in the autoconf-script
407 * Collection/Museum scripts have been added unter contrib/museum
408 * collectd may now be started in unprivileged mode, though ping
409 statistics will not work.
411 2005-07-17, Version 1.5.1:
412 * Diskstats-RRDs now use major/minor for naming. Some systems have
413 weird strings as disk-names..
415 2005-07-17, Version 1.5:
416 * A new module, diskstats, has been added. It collects information
417 about the disks and partitions.
419 2005-07-11, Version 1.4.2:
420 * The meminfo mofule has been changed to work with more platforms
421 and/or kernel versions.
423 2005-07-10, Version 1.4.1: Correct traffic stats
424 * The traffic rrd-file is now created with DS-type `COUNTER' which I
425 forgot to correct when I changed that module.
427 2005-07-09, Version 1.4: More traffic stats
428 * Traffic is now collected for all interfaces that can be found
429 * Temperature-statistics are read from lm-sensors if available
431 2005-07-08, Version 1.3: CPU stats

439 2004-07-10, Version 1.1: Minor changes
440 * Nothing really usefull to say ;)
442 2004-07-09, Version 1.0: Initial Version
443 * The following modules are provided:
