1 2007-07-30, Version 4.0.6
2 * sensors plugin: Fix the ignorelist functionality: Only the `type
3 instance' was used to match against the list, but the documentation
4 told otherwise. This release fixes the code, so it complies with the
7 2007-07-05, Version 4.0.5
8 * Portability: More fixes for OpenBSD have been included.
10 2007-06-24, Version 4.0.4
11 * cpu plugin: Fixed the Solaris code.
12 * dns plugin: Fixed a build issue for OpenBSD.
13 * interface plugin: Fixed the Solaris code.
14 * load plugin: Fixed the alternative `/proc' Linux code.
15 * memory plugin: Fixed the Solaris code.
16 * oconfig: Don't require `-lfl' anymore.
18 2007-06-19, Version 4.0.3
19 * cpu plugin: Fix the Darwin / Mac OS X code.
20 * ping plugin: Use the return value of `getpid', not its address.
21 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
22 initialized correctly.
23 * configure: Added `--with-nan-emulation' to aid cross compilation.
25 2007-06-12, Version 4.0.2
26 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
27 they're given in numerically form.
29 2007-06-07, Version 4.0.1
30 * iptables plugin: A bug in the configuration routine has been fixed.
31 Setting a comment in the configfile will no longer cause a
34 2007-06-03, Version 4.0.0
35 * collectd: The plugin-infrastructure has been changed to allow for
36 more types of plugins, namely `write' and `log' plugins.
37 * collectd: The read-function has been changed to read many plugins in
38 parallel, using threads. Thus, plugins generally need to use
39 thread-safe functions from now on.
40 * collectd: The '-t' command line options allows to perform syntax tests
41 of the configuration file and exit immediately.
42 * csv plugin: The new `csv' plugin handles output to `comma separated
44 * rrdtool plugin: The new `rrdtool' plugin handles output to
45 RRD-files. Data can be cached to combine multiple updates into one
46 write to increase IO-performance.
47 * network plugin: The new `network' plugin handles IO via the network.
48 It implements a different, much more extensible protocol which can
49 combine many values in one packet, decreasing the number of UDP-
50 packets being sent. It can read from and send to the network and
51 with the appropriate configuration even forward packets to other
53 * unixsock plugin: The new `unixsock' plugin provides an interface to
54 communicate with the daemon while it is running. Right now the
55 commands `GETVAL' and `PUTVAL' are implemented, but more are to
57 * perl plugin: The new `perl' plugin allows you to write extensions
58 for collectd in the scripting-language Perl.
59 * logfile plugin: The new `logfile' plugin writes logmessages to files
61 * syslog plugin: The new `syslog' plugin sends logmessages to the
62 system's syslog daemon.
63 * entropy plugin: The new `entropy' plugin collects the amount of
64 entropy currently being available to the system.
65 * exec plugin: The new `exec' plugin forks child processes and reads
66 back values provided by the forked processes.
67 * iptables plugin: The new `iptables' plugin reads counters from
68 iptables rules. Thanks to Sjoerd van der Berg for contributing this
70 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
71 to Peter Holik for contributing this plugin.
72 * nut plugin: The new `nut' plugin connects the upsd of the `network
73 ups tools' and reads information about the connected UPS.
74 * apache plugin: Support for lighttpd's `BusyServers' (aka.
75 connections) field was added by Florent Monbillard.
76 * collectd-nagios: The new `collectd-nagios' binary queries values
77 from collectd, parses them and exits according to Nagios-standards.
78 * manpages: The manpages have been improved a lot.
80 2007-05-29, Version 3.11.5
81 * configure: Added `AC_SYS_LARGEFILE' for LFS.
82 * ntpd plugin: Fix a potential buffer overflow.
83 * processes plugin: Fix a bug when run under Linux 2.4. All processes
84 were accounted as `zombies'.
86 2007-04-10, Version 3.11.4
87 * dns plugin: Change the order of includes to make the plugin compile
90 2007-03-30, Version 3.11.3
91 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
92 of the unused `COLLECT_KSTAT'.
94 2007-02-11, Version 3.11.2
95 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
96 NULL-pointer may have been passed to `printf' which causes a
97 segfault with some libcs.
99 2007-02-10, Version 3.11.1
100 * df plugin: Some wrong defines have been fixed so the plugin works
102 * dns plugin: The usage of a struct has been fixed to work with
104 * processes plugin: Some missing defines have been added so the plugin
105 compiles cleanly under FreeBSD and presumably other UNIXes.
107 2006-12-22, Version 3.11.0
108 * collectd: The new command line option `-P' makes it easier for
109 distributors to change the location of PID-files.
110 * collectd: The daemon shuts down faster now which makes it easier to
111 write init.d-scripts for it.
112 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
113 caused problems every now and then.
114 * df plugin: New config options allow to ignore certain mountpoints,
115 filesystem types or devices.
116 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
117 and interprets it. It collects traffic as well as qtype, opcode and
119 * email plugin: Sebastian Harl has contributed this plugin which
120 counts received mails in categories (e. g. ham, spam, virus), spam
121 score (as given by SpamAssassin) and check types.
122 * mbmon plugin: Flavio Stanchina has contributed this plugin which
123 uses `mbmon' to gather information from sensors on the motherboard.
124 * processes plugin: Collect detailed statistics for configured
125 processes, that's process and thread count, CPU usage, resident
126 segment size and pagefaults.
127 * multimeter plugin: Peter Holik contributed a new plugin which
129 * sensors plugin: Lubos Stanek has put much effort into improving this
130 plugin, including `extended naming', collection of voltage values
131 and the possibility to ignore certain values.
133 2006-12-21, Version 3.10.4
134 * Max Kellermann has identified a bug in the server routine: When
135 opening a socket fails the daemon will (re)try opening the socket in
136 an endless loop, ultimately leading to a `EMFILE' error.
138 2006-11-04, Version 3.10.3
139 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
140 ntpd's reply was sent in more than one packet, the buffer size was
141 calculated incorrectly, resulting in the reading of uninitialized or
144 2006-11-01, Version 3.10.2
145 * The sample config file has been improved.
146 * Errors in the manpages have been corrected.
147 * The ping-plugin now adds hosts during initialization, not during
148 startup. This speeds up starup when no network connectivity is
149 available. Also, the hosts are being added later when the network is
151 * Improved BSD-support for the df-plugin.
152 * Fixed syntax errors in the swap-plugin for Mac OS X.
153 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
155 * Don't disable the mysql-plugin if connecting to the database fails
156 during initialization. Instead, try again in increasing intervals.
158 2006-07-19, Version 3.10.1
159 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
160 the apcups cannot be reached, unconnected sockets will pile up and
161 eventually lead to `Too many open files' errors.
163 2006-07-09, Version 3.10.0
164 * The `disk' plugin has been ported to Darwin.
165 * The `battery' plugin should work on many Apple computers now.
166 * The `traffic' plugin can now ignore certain interfaces. Also,
167 statistics for sent/received packets and errors have been added.
168 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
169 to Anthony Gialluca for contributing this plugin and providing me
170 with a test environment :)
171 * A plugin for moniroting an NTP instance and the local clock drift
174 2006-06-25, Version 3.9.4
175 * The Solaris code in the `swap' plugin has been changed to reflect
176 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
178 * The debugging system has been fixed to work with the Sun libc.
179 * When built without librrd the variable `operating_mode' could be
180 uninitialized. Thanks to David Elliot for reporting the bug.
182 2006-06-01, Version 3.9.3
183 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
184 operating systems also profit from the changes, but I wasn't able to
186 * Changed the build system to find the netinet-includes under FreeBSD
187 and therefore successfully build the `liboping' library there.
189 2006-05-09, Version 3.9.2
190 * Applied a patch to the `liboping' library. Due to a bug in the
191 sequence checking the `ping' plugin stopped working after
192 approximately 7.6 days.
194 2006-05-09, Version 3.8.5
195 * Applied a patch to the `liboping' library. Due to a bug in the
196 sequence checking the `ping' plugin stopped working after
197 approximately 7.6 days.
199 2006-04-21, Version 3.9.1
200 * Build issues with Solaris and possible other architectures have been
202 * Problems when building the `apache'-plugin without `libcurl' have
204 * A bug in the `ping' plugin has been fixed. Sorry folks.

207 * A plugin to monitor the Apache webserver has been added.
208 <http://httpd.apache.org/>
209 * A plugin to collect statistics about virtual servers using VServer.
210 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

213 strength, link quality and noise ratio..
214 * A plugin for Apple hardware sensors has been added.
215 * An option to compile collectd with different `step' and `hearbeat'
216 settings has been added. The size of RRAs is no longer static but
217 calculated based on the settings for `step' and `width'.
218 * The `ping' plugin can now be configured to use a certain TTL.
219 * A plugin to monitor the hardware sensors of Apple computers has been
221 * The plugins `cpu', `memory', `processes' and `traffic' have been
222 ported to Mach/Darwin (Mac OS X).
223 * The `log mode' has been contributed by Christophe Kalt. It writes
224 the data into text files rather than RRD files.
226 2006-04-09, Version 3.8.4
227 * Applied patch by Vincent Stehlé which improves the disk-name
228 resolution in the `hddtemp' plugin for Linux systems.
230 2006-04-02, Version 3.8.3
231 * Applied a patch by James Byers: The MySQL plugin was not working
232 with MySQL 5.0.2 or later.
234 2006-03-14, Version 3.8.2
235 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
236 the GNU libc, because it points to `/etc/fstab' rather than
239 2006-03-13, Version 3.8.1
240 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
241 * Fixes in the debian `postinst' and `init.d' scripts.
243 2006-03-09, Version 3.8.0
244 * The `ping' plugin no longer uses `libping' but a self written
245 library named `liboping'. With this library it's possible to ping
246 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
248 2006-02-18, Version 3.7.2
249 * A simple bug in the `battery' plugin has been fixed. It should now
250 work with ACPI based batteries as well. Thankt to Sebastian for
252 * Fixing a bug that prevented collectd to be built without librrd.
253 Thanks to Werner Heuser for reporting it.
255 2006-02-04, Version 3.7.1
256 * The new network code has been improved to build with older versions

259 to Tommie Gannert for this patch.
261 2006-01-30, Version 3.7.0
262 * The `battery' plugin has been added. It collects information about
264 * The MySQL plugin has been improved: It now writes two more RRD
265 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
266 * The `cpufreq' plugin now reads another file since the file it did
267 read so far causes much overhead in the kernel. Also, you need root
268 to read the old file, but not to read the new one.
269 * The `hddtemp' plugin can now be configured to connect to another
270 address and/or port than localhost.
271 * The `df' plugin now prefers `statvfs' over `statfs'.
272 * The network code has been rewritten. collectd now supports unicast
273 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
274 be set in the configfile.
276 2006-01-24, Version 3.6.2
277 * Due to a bug in the configfile handling collectd wouldn't start in
278 client mode. This released fixes this.
280 2006-01-20, Version 3.6.1
281 * Due to a bug in `configure.in' all modules and the binary were
282 linked against `libmysqlclient'. This issue is solved by this
285 2006-01-17, Version 3.6.0
286 * A config file has been added. This allows for loading only specific
288 * A `df' plugin has been added.
289 * A `mysql' plugin has been added.
290 * The `ping' plugin doesn't entirely give up hope when a socket error
291 occured, but will back of and increase the intervals between tries.
293 2006-01-21, Version 3.5.2
294 * Fixed yet another bug in the signal handling.. Stupid typo..
295 * Improved the ping plugin to not give up on socket errors (backport
298 2005-12-18, Version 3.5.1
299 * The PID-file is now deleted correctly when shutting down the daemon.
300 * SIGINT and SIGTERM are now handled correctly.
302 2005-12-16, Version 3.5.0 (Revision 326)
303 * A bug in the `load' module under Solaris has been fixed.
304 * The `users' module has been contributed by Sebastian Harl. It counts
305 currently logged in users.
306 * The CPU module now works under FreeBSD without the use of
307 `libstatgrab', however SMP support is missing.
308 * The default directories for the RRD files and the PID file now
309 depend on the compile time setting of `localstatedir'.
311 2005-11-15, Version 3.4.0 (Revision 236)
312 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
313 from gentoo's bugzilla for writing the patch.
314 * The build dependency for librrd has been removed. Binaries built
315 without librrd are client-only and will multicast their value as
316 with the `-c' argument.
317 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
318 * The newly introduced `-f' switch prevents daemon initialization
319 (forking, closing standard filehandles, etc.) Thanks to Alvaro
320 Barcellos for this patch.
322 2005-11-04, Version 3.3.0 (Revision 216)
323 * New modules have been added:
324 - `serial', for monitoring traffic on the serial interfaces
325 - `nfs', for graphing NFS procedure calls
326 - `tape', traffic from/to tape devices
327 * The the memory.rrd now accepts more than 4Gig of memory.
329 2005-10-26, Version 3.2.0 (Revision 200)
330 * Support for graphing the processes has been added (thanks to Lyonel

335 * Problems with the spec file have been fixed.
337 2005-10-16, Version 3.1.0 (Revision 194)
338 * Added the `setsid' syscall to the startup code.
339 * Support for hddtemp has been added (thanks to Vincent Stehlé)
341 2005-09-30, Version 3.0.0 (Revision 184)
342 * The ability to send/receive data to/from the network (think
343 multicast) has been added.
344 * Modules have been split up into shared libraries can be loaded at
345 runtime. The biggest advantage is that the core program doesn't need
346 to be linked against an external library.
347 * A patch by George Kargiotakis has been applied: It fixes the sensors
348 behaviour then more than one sensor is being queried.
350 2005-09-16, Version 2.1.0 (Revision 172)
351 * A module for swap statistics has been added.
353 2005-09-09, Version 2.0.0 (Revision 135)
354 * Filenames can no longer be configured at program startup. The only
355 options as of this version are the directory and ping hosts.
356 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
357 Soft-IRQ statistics are added to `System'.
358 * Diskstats now collect read and write bytes, not sectors.
359 * Ping statistics can now be collected for more than one host. There
360 is no default any more: If no host is given no host will be pinged.
361 * A self-written patch for libping has been applied so it builds
364 2005-09-01, Version 1.8.1 (Revision 123)
365 * Much improved configure-script: libraries and features may now be
367 * More detailed warnings/error messages when RRD update failes.
369 2005-08-29, Version 1.8.0:
370 * Support for collecting disk statistics under Solaris.
372 2005-08-25, Version 1.7.0:
373 * Support for libstatgrab[1] for load, memory usage and network
374 traffic. CPU- and disk-usage are not (yet) supported, since
375 libstatgrab returns insufficient information. I will contact the
377 * Improved the CPU-initialization code for Solaris. Apparently CPUs
378 aren't neccessarily counted linear which is now handled correctly.
379 [1]: http://www.i-scream.org/libstatgrab/
381 2005-08-21, Version 1.6.0:
382 * Basic support for Solaris: System load and cpu-usage can be
383 collected unter Solaris, too. Other stats will follow later.
384 * Many fixes in the autoconf-script
385 * Collection/Museum scripts have been added unter contrib/museum
386 * collectd may now be started in unprivileged mode, though ping
387 statistics will not work.
389 2005-07-17, Version 1.5.1:
390 * Diskstats-RRDs now use major/minor for naming. Some systems have
391 weird strings as disk-names..
393 2005-07-17, Version 1.5:
394 * A new module, diskstats, has been added. It collects information
395 about the disks and partitions.
397 2005-07-11, Version 1.4.2:
398 * The meminfo mofule has been changed to work with more platforms
399 and/or kernel versions.
401 2005-07-10, Version 1.4.1: Correct traffic stats
402 * The traffic rrd-file is now created with DS-type `COUNTER' which I
403 forgot to correct when I changed that module.
405 2005-07-09, Version 1.4: More traffic stats
406 * Traffic is now collected for all interfaces that can be found
407 * Temperature-statistics are read from lm-sensors if available
409 2005-07-08, Version 1.3: CPU stats
410 * Collecting CPU statistics now
412 2004-07-12, Version 1.2: Using syslog
413 * collectd is now using the syslog facility to report errors, warnings
415 * The default directory is now /var/db/collectd
417 2004-07-10, Version 1.1: Minor changes
418 * Nothing really usefull to say ;)
420 2004-07-09, Version 1.0: Initial Version
421 * The following modules are provided:
