1 2007-06-19, Version 4.0.3
2 * cpu plugin: Fix the Darwin / Mac OS X code.
3 * ping plugin: Use the return value of `getpid', not its address.
4 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
6 * configure: Added `--with-nan-emulation' to aid cross compilation.
8 2007-06-12, Version 4.0.2
9 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
10 they're given in numerically form.
12 2007-06-07, Version 4.0.1
13 * iptables plugin: A bug in the configuration routine has been fixed.
14 Setting a comment in the configfile will no longer cause a
17 2007-06-03, Version 4.0.0
18 * collectd: The plugin-infrastructure has been changed to allow for
19 more types of plugins, namely `write' and `log' plugins.
20 * collectd: The read-function has been changed to read many plugins in
21 parallel, using threads. Thus, plugins generally need to use
22 thread-safe functions from now on.
23 * collectd: The '-t' command line options allows to perform syntax tests
24 of the configuration file and exit immediately.
25 * csv plugin: The new `csv' plugin handles output to `comma separated
27 * rrdtool plugin: The new `rrdtool' plugin handles output to
28 RRD-files. Data can be cached to combine multiple updates into one
29 write to increase IO-performance.
30 * network plugin: The new `network' plugin handles IO via the network.
31 It implements a different, much more extensible protocol which can
32 combine many values in one packet, decreasing the number of UDP-
33 packets being sent. It can read from and send to the network and
34 with the appropriate configuration even forward packets to other
36 * unixsock plugin: The new `unixsock' plugin provides an interface to
37 communicate with the daemon while it is running. Right now the
38 commands `GETVAL' and `PUTVAL' are implemented, but more are to
40 * perl plugin: The new `perl' plugin allows you to write extensions
41 for collectd in the scripting-language Perl.
42 * logfile plugin: The new `logfile' plugin writes logmessages to files
44 * syslog plugin: The new `syslog' plugin sends logmessages to the
45 system's syslog daemon.
46 * entropy plugin: The new `entropy' plugin collects the amount of
47 entropy currently being available to the system.
48 * exec plugin: The new `exec' plugin forks child processes and reads
49 back values provided by the forked processes.
50 * iptables plugin: The new `iptables' plugin reads counters from
51 iptables rules. Thanks to Sjoerd van der Berg for contributing this
53 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
54 to Peter Holik for contributing this plugin.
55 * nut plugin: The new `nut' plugin connects the upsd of the `network
56 ups tools' and reads information about the connected UPS.
57 * apache plugin: Support for lighttpd's `BusyServers' (aka.
58 connections) field was added by Florent Monbillard.
59 * collectd-nagios: The new `collectd-nagios' binary queries values
60 from collectd, parses them and exits according to Nagios-standards.
61 * manpages: The manpages have been improved a lot.
63 2007-05-29, Version 3.11.5
64 * configure: Added `AC_SYS_LARGEFILE' for LFS.
65 * ntpd plugin: Fix a potential buffer overflow.
66 * processes plugin: Fix a bug when run under Linux 2.4. All processes
67 were accounted as `zombies'.
69 2007-04-10, Version 3.11.4
70 * dns plugin: Change the order of includes to make the plugin compile
73 2007-03-30, Version 3.11.3
74 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
75 of the unused `COLLECT_KSTAT'.
77 2007-02-11, Version 3.11.2
78 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
79 NULL-pointer may have been passed to `printf' which causes a
80 segfault with some libcs.
82 2007-02-10, Version 3.11.1
83 * df plugin: Some wrong defines have been fixed so the plugin works
85 * dns plugin: The usage of a struct has been fixed to work with
87 * processes plugin: Some missing defines have been added so the plugin
88 compiles cleanly under FreeBSD and presumably other UNIXes.
90 2006-12-22, Version 3.11.0
91 * collectd: The new command line option `-P' makes it easier for
92 distributors to change the location of PID-files.
93 * collectd: The daemon shuts down faster now which makes it easier to
94 write init.d-scripts for it.
95 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
96 caused problems every now and then.
97 * df plugin: New config options allow to ignore certain mountpoints,
98 filesystem types or devices.
99 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
100 and interprets it. It collects traffic as well as qtype, opcode and
102 * email plugin: Sebastian Harl has contributed this plugin which
103 counts received mails in categories (e. g. ham, spam, virus), spam
104 score (as given by SpamAssassin) and check types.
105 * mbmon plugin: Flavio Stanchina has contributed this plugin which
106 uses `mbmon' to gather information from sensors on the motherboard.
107 * processes plugin: Collect detailed statistics for configured
108 processes, that's process and thread count, CPU usage, resident
109 segment size and pagefaults.
110 * multimeter plugin: Peter Holik contributed a new plugin which
112 * sensors plugin: Lubos Stanek has put much effort into improving this
113 plugin, including `extended naming', collection of voltage values
114 and the possibility to ignore certain values.
116 2006-12-21, Version 3.10.4
117 * Max Kellermann has identified a bug in the server routine: When
118 opening a socket fails the daemon will (re)try opening the socket in
119 an endless loop, ultimately leading to a `EMFILE' error.
121 2006-11-04, Version 3.10.3
122 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
123 ntpd's reply was sent in more than one packet, the buffer size was
124 calculated incorrectly, resulting in the reading of uninitialized or
127 2006-11-01, Version 3.10.2
128 * The sample config file has been improved.
129 * Errors in the manpages have been corrected.
130 * The ping-plugin now adds hosts during initialization, not during
131 startup. This speeds up starup when no network connectivity is
132 available. Also, the hosts are being added later when the network is
134 * Improved BSD-support for the df-plugin.
135 * Fixed syntax errors in the swap-plugin for Mac OS X.
136 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
138 * Don't disable the mysql-plugin if connecting to the database fails
139 during initialization. Instead, try again in increasing intervals.
141 2006-07-19, Version 3.10.1
142 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
143 the apcups cannot be reached, unconnected sockets will pile up and
144 eventually lead to `Too many open files' errors.
146 2006-07-09, Version 3.10.0
147 * The `disk' plugin has been ported to Darwin.
148 * The `battery' plugin should work on many Apple computers now.
149 * The `traffic' plugin can now ignore certain interfaces. Also,
150 statistics for sent/received packets and errors have been added.
151 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
152 to Anthony Gialluca for contributing this plugin and providing me
153 with a test environment :)
154 * A plugin for moniroting an NTP instance and the local clock drift
157 2006-06-25, Version 3.9.4
158 * The Solaris code in the `swap' plugin has been changed to reflect
159 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
161 * The debugging system has been fixed to work with the Sun libc.
162 * When built without librrd the variable `operating_mode' could be
163 uninitialized. Thanks to David Elliot for reporting the bug.
165 2006-06-01, Version 3.9.3
166 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
167 operating systems also profit from the changes, but I wasn't able to
169 * Changed the build system to find the netinet-includes under FreeBSD
170 and therefore successfully build the `liboping' library there.
172 2006-05-09, Version 3.9.2
173 * Applied a patch to the `liboping' library. Due to a bug in the
174 sequence checking the `ping' plugin stopped working after
175 approximately 7.6 days.
177 2006-05-09, Version 3.8.5
178 * Applied a patch to the `liboping' library. Due to a bug in the
179 sequence checking the `ping' plugin stopped working after
180 approximately 7.6 days.
182 2006-04-21, Version 3.9.1
183 * Build issues with Solaris and possible other architectures have been
185 * Problems when building the `apache'-plugin without `libcurl' have
187 * A bug in the `ping' plugin has been fixed. Sorry folks.
189 2006-04-02, Version 3.9.0
190 * A plugin to monitor the Apache webserver has been added.
191 <http://httpd.apache.org/>
192 * A plugin to collect statistics about virtual servers using VServer.
193 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

196 strength, link quality and noise ratio..
197 * A plugin for Apple hardware sensors has been added.
198 * An option to compile collectd with different `step' and `hearbeat'
199 settings has been added. The size of RRAs is no longer static but
200 calculated based on the settings for `step' and `width'.
201 * The `ping' plugin can now be configured to use a certain TTL.
202 * A plugin to monitor the hardware sensors of Apple computers has been
204 * The plugins `cpu', `memory', `processes' and `traffic' have been
205 ported to Mach/Darwin (Mac OS X).
206 * The `log mode' has been contributed by Christophe Kalt. It writes
207 the data into text files rather than RRD files.
209 2006-04-09, Version 3.8.4
210 * Applied patch by Vincent Stehlé which improves the disk-name
211 resolution in the `hddtemp' plugin for Linux systems.
213 2006-04-02, Version 3.8.3
214 * Applied a patch by James Byers: The MySQL plugin was not working
215 with MySQL 5.0.2 or later.
217 2006-03-14, Version 3.8.2
218 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
219 the GNU libc, because it points to `/etc/fstab' rather than
222 2006-03-13, Version 3.8.1
223 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
224 * Fixes in the debian `postinst' and `init.d' scripts.
226 2006-03-09, Version 3.8.0
227 * The `ping' plugin no longer uses `libping' but a self written
228 library named `liboping'. With this library it's possible to ping
229 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
231 2006-02-18, Version 3.7.2
232 * A simple bug in the `battery' plugin has been fixed. It should now
233 work with ACPI based batteries as well. Thankt to Sebastian for
235 * Fixing a bug that prevented collectd to be built without librrd.
236 Thanks to Werner Heuser for reporting it.
238 2006-02-04, Version 3.7.1
239 * The new network code has been improved to build with older versions

244 2006-01-30, Version 3.7.0
245 * The `battery' plugin has been added. It collects information about
247 * The MySQL plugin has been improved: It now writes two more RRD
248 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
249 * The `cpufreq' plugin now reads another file since the file it did
250 read so far causes much overhead in the kernel. Also, you need root
251 to read the old file, but not to read the new one.
252 * The `hddtemp' plugin can now be configured to connect to another
253 address and/or port than localhost.
254 * The `df' plugin now prefers `statvfs' over `statfs'.
255 * The network code has been rewritten. collectd now supports unicast
256 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
257 be set in the configfile.
259 2006-01-24, Version 3.6.2
260 * Due to a bug in the configfile handling collectd wouldn't start in
261 client mode. This released fixes this.
263 2006-01-20, Version 3.6.1
264 * Due to a bug in `configure.in' all modules and the binary were
265 linked against `libmysqlclient'. This issue is solved by this
268 2006-01-17, Version 3.6.0
269 * A config file has been added. This allows for loading only specific
271 * A `df' plugin has been added.
272 * A `mysql' plugin has been added.
273 * The `ping' plugin doesn't entirely give up hope when a socket error
274 occured, but will back of and increase the intervals between tries.
276 2006-01-21, Version 3.5.2
277 * Fixed yet another bug in the signal handling.. Stupid typo..
278 * Improved the ping plugin to not give up on socket errors (backport
281 2005-12-18, Version 3.5.1
282 * The PID-file is now deleted correctly when shutting down the daemon.
283 * SIGINT and SIGTERM are now handled correctly.
285 2005-12-16, Version 3.5.0 (Revision 326)
286 * A bug in the `load' module under Solaris has been fixed.
287 * The `users' module has been contributed by Sebastian Harl. It counts
288 currently logged in users.
289 * The CPU module now works under FreeBSD without the use of
290 `libstatgrab', however SMP support is missing.
291 * The default directories for the RRD files and the PID file now
292 depend on the compile time setting of `localstatedir'.
294 2005-11-15, Version 3.4.0 (Revision 236)
295 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
296 from gentoo's bugzilla for writing the patch.
297 * The build dependency for librrd has been removed. Binaries built
298 without librrd are client-only and will multicast their value as
299 with the `-c' argument.
300 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
301 * The newly introduced `-f' switch prevents daemon initialization
302 (forking, closing standard filehandles, etc.) Thanks to Alvaro
303 Barcellos for this patch.
305 2005-11-04, Version 3.3.0 (Revision 216)
306 * New modules have been added:
307 - `serial', for monitoring traffic on the serial interfaces
308 - `nfs', for graphing NFS procedure calls
309 - `tape', traffic from/to tape devices
310 * The the memory.rrd now accepts more than 4Gig of memory.
312 2005-10-26, Version 3.2.0 (Revision 200)
313 * Support for graphing the processes has been added (thanks to Lyonel

318 * Problems with the spec file have been fixed.
320 2005-10-16, Version 3.1.0 (Revision 194)
321 * Added the `setsid' syscall to the startup code.
322 * Support for hddtemp has been added (thanks to Vincent Stehlé)
324 2005-09-30, Version 3.0.0 (Revision 184)
325 * The ability to send/receive data to/from the network (think
326 multicast) has been added.
327 * Modules have been split up into shared libraries can be loaded at
328 runtime. The biggest advantage is that the core program doesn't need
329 to be linked against an external library.
330 * A patch by George Kargiotakis has been applied: It fixes the sensors
331 behaviour then more than one sensor is being queried.
333 2005-09-16, Version 2.1.0 (Revision 172)
334 * A module for swap statistics has been added.
336 2005-09-09, Version 2.0.0 (Revision 135)
337 * Filenames can no longer be configured at program startup. The only
338 options as of this version are the directory and ping hosts.
339 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
340 Soft-IRQ statistics are added to `System'.
341 * Diskstats now collect read and write bytes, not sectors.
342 * Ping statistics can now be collected for more than one host. There
343 is no default any more: If no host is given no host will be pinged.
344 * A self-written patch for libping has been applied so it builds
347 2005-09-01, Version 1.8.1 (Revision 123)
348 * Much improved configure-script: libraries and features may now be
350 * More detailed warnings/error messages when RRD update failes.
352 2005-08-29, Version 1.8.0:
353 * Support for collecting disk statistics under Solaris.
355 2005-08-25, Version 1.7.0:
356 * Support for libstatgrab[1] for load, memory usage and network
357 traffic. CPU- and disk-usage are not (yet) supported, since
358 libstatgrab returns insufficient information. I will contact the
360 * Improved the CPU-initialization code for Solaris. Apparently CPUs
361 aren't neccessarily counted linear which is now handled correctly.
362 [1]: http://www.i-scream.org/libstatgrab/
364 2005-08-21, Version 1.6.0:
365 * Basic support for Solaris: System load and cpu-usage can be
366 collected unter Solaris, too. Other stats will follow later.
367 * Many fixes in the autoconf-script
368 * Collection/Museum scripts have been added unter contrib/museum
369 * collectd may now be started in unprivileged mode, though ping
370 statistics will not work.
372 2005-07-17, Version 1.5.1:
373 * Diskstats-RRDs now use major/minor for naming. Some systems have
374 weird strings as disk-names..
376 2005-07-17, Version 1.5:
377 * A new module, diskstats, has been added. It collects information
378 about the disks and partitions.
380 2005-07-11, Version 1.4.2:
381 * The meminfo mofule has been changed to work with more platforms
382 and/or kernel versions.
384 2005-07-10, Version 1.4.1: Correct traffic stats
385 * The traffic rrd-file is now created with DS-type `COUNTER' which I
386 forgot to correct when I changed that module.
388 2005-07-09, Version 1.4: More traffic stats
389 * Traffic is now collected for all interfaces that can be found
390 * Temperature-statistics are read from lm-sensors if available
392 2005-07-08, Version 1.3: CPU stats

400 2004-07-10, Version 1.1: Minor changes
401 * Nothing really usefull to say ;)
403 2004-07-09, Version 1.0: Initial Version
404 * The following modules are provided:
