1 2007-06-07, Version 4.0.1
2 * iptables plugin: A bug in the configuration routine has been fixed.
3 Setting a comment in the configfile will no longer cause a
6 2007-06-03, Version 4.0.0
7 * collectd: The plugin-infrastructure has been changed to allow for
8 more types of plugins, namely `write' and `log' plugins.
9 * collectd: The read-function has been changed to read many plugins in
10 parallel, using threads. Thus, plugins generally need to use
11 thread-safe functions from now on.
12 * collectd: The '-t' command line options allows to perform syntax tests
13 of the configuration file and exit immediately.
14 * csv plugin: The new `csv' plugin handles output to `comma separated
16 * rrdtool plugin: The new `rrdtool' plugin handles output to
17 RRD-files. Data can be cached to combine multiple updates into one
18 write to increase IO-performance.
19 * network plugin: The new `network' plugin handles IO via the network.
20 It implements a different, much more extensible protocol which can
21 combine many values in one packet, decreasing the number of UDP-
22 packets being sent. It can read from and send to the network and
23 with the appropriate configuration even forward packets to other
25 * unixsock plugin: The new `unixsock' plugin provides an interface to
26 communicate with the daemon while it is running. Right now the
27 commands `GETVAL' and `PUTVAL' are implemented, but more are to
29 * perl plugin: The new `perl' plugin allows you to write extensions
30 for collectd in the scripting-language Perl.
31 * logfile plugin: The new `logfile' plugin writes logmessages to files
33 * syslog plugin: The new `syslog' plugin sends logmessages to the
34 system's syslog daemon.
35 * entropy plugin: The new `entropy' plugin collects the amount of
36 entropy currently being available to the system.
37 * exec plugin: The new `exec' plugin forks child processes and reads
38 back values provided by the forked processes.
39 * iptables plugin: The new `iptables' plugin reads counters from
40 iptables rules. Thanks to Sjoerd van der Berg for contributing this
42 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
43 to Peter Holik for contributing this plugin.
44 * nut plugin: The new `nut' plugin connects the upsd of the `network
45 ups tools' and reads information about the connected UPS.
46 * apache plugin: Support for lighttpd's `BusyServers' (aka.
47 connections) field was added by Florent Monbillard.
48 * collectd-nagios: The new `collectd-nagios' binary queries values
49 from collectd, parses them and exits according to Nagios-standards.
50 * manpages: The manpages have been improved a lot.
52 2007-05-29, Version 3.11.5
53 * configure: Added `AC_SYS_LARGEFILE' for LFS.
54 * ntpd plugin: Fix a potential buffer overflow.
55 * processes plugin: Fix a bug when run under Linux 2.4. All processes
56 were accounted as `zombies'.
58 2007-04-10, Version 3.11.4
59 * dns plugin: Change the order of includes to make the plugin compile
62 2007-03-30, Version 3.11.3
63 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
64 of the unused `COLLECT_KSTAT'.
66 2007-02-11, Version 3.11.2
67 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
68 NULL-pointer may have been passed to `printf' which causes a
69 segfault with some libcs.
71 2007-02-10, Version 3.11.1
72 * df plugin: Some wrong defines have been fixed so the plugin works
74 * dns plugin: The usage of a struct has been fixed to work with
76 * processes plugin: Some missing defines have been added so the plugin
77 compiles cleanly under FreeBSD and presumably other UNIXes.
79 2006-12-22, Version 3.11.0
80 * collectd: The new command line option `-P' makes it easier for
81 distributors to change the location of PID-files.
82 * collectd: The daemon shuts down faster now which makes it easier to
83 write init.d-scripts for it.
84 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
85 caused problems every now and then.
86 * df plugin: New config options allow to ignore certain mountpoints,
87 filesystem types or devices.
88 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
89 and interprets it. It collects traffic as well as qtype, opcode and
91 * email plugin: Sebastian Harl has contributed this plugin which
92 counts received mails in categories (e. g. ham, spam, virus), spam
93 score (as given by SpamAssassin) and check types.
94 * mbmon plugin: Flavio Stanchina has contributed this plugin which
95 uses `mbmon' to gather information from sensors on the motherboard.
96 * processes plugin: Collect detailed statistics for configured
97 processes, that's process and thread count, CPU usage, resident
98 segment size and pagefaults.
99 * multimeter plugin: Peter Holik contributed a new plugin which
101 * sensors plugin: Lubos Stanek has put much effort into improving this
102 plugin, including `extended naming', collection of voltage values
103 and the possibility to ignore certain values.
105 2006-12-21, Version 3.10.4
106 * Max Kellermann has identified a bug in the server routine: When
107 opening a socket fails the daemon will (re)try opening the socket in
108 an endless loop, ultimately leading to a `EMFILE' error.
110 2006-11-04, Version 3.10.3
111 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
112 ntpd's reply was sent in more than one packet, the buffer size was
113 calculated incorrectly, resulting in the reading of uninitialized or
116 2006-11-01, Version 3.10.2
117 * The sample config file has been improved.
118 * Errors in the manpages have been corrected.
119 * The ping-plugin now adds hosts during initialization, not during
120 startup. This speeds up starup when no network connectivity is
121 available. Also, the hosts are being added later when the network is
123 * Improved BSD-support for the df-plugin.
124 * Fixed syntax errors in the swap-plugin for Mac OS X.
125 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
127 * Don't disable the mysql-plugin if connecting to the database fails
128 during initialization. Instead, try again in increasing intervals.
130 2006-07-19, Version 3.10.1
131 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
132 the apcups cannot be reached, unconnected sockets will pile up and
133 eventually lead to `Too many open files' errors.
135 2006-07-09, Version 3.10.0
136 * The `disk' plugin has been ported to Darwin.
137 * The `battery' plugin should work on many Apple computers now.
138 * The `traffic' plugin can now ignore certain interfaces. Also,
139 statistics for sent/received packets and errors have been added.
140 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
141 to Anthony Gialluca for contributing this plugin and providing me
142 with a test environment :)
143 * A plugin for moniroting an NTP instance and the local clock drift
146 2006-06-25, Version 3.9.4
147 * The Solaris code in the `swap' plugin has been changed to reflect
148 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
150 * The debugging system has been fixed to work with the Sun libc.
151 * When built without librrd the variable `operating_mode' could be
152 uninitialized. Thanks to David Elliot for reporting the bug.
154 2006-06-01, Version 3.9.3
155 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
156 operating systems also profit from the changes, but I wasn't able to
158 * Changed the build system to find the netinet-includes under FreeBSD
159 and therefore successfully build the `liboping' library there.
161 2006-05-09, Version 3.9.2
162 * Applied a patch to the `liboping' library. Due to a bug in the
163 sequence checking the `ping' plugin stopped working after
164 approximately 7.6 days.
166 2006-05-09, Version 3.8.5
167 * Applied a patch to the `liboping' library. Due to a bug in the
168 sequence checking the `ping' plugin stopped working after
169 approximately 7.6 days.
171 2006-04-21, Version 3.9.1
172 * Build issues with Solaris and possible other architectures have been
174 * Problems when building the `apache'-plugin without `libcurl' have
176 * A bug in the `ping' plugin has been fixed. Sorry folks.
178 2006-04-02, Version 3.9.0
179 * A plugin to monitor the Apache webserver has been added.
180 <http://httpd.apache.org/>
181 * A plugin to collect statistics about virtual servers using VServer.
182 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
184 * A plugin for wireless LAN cards has been added. It monitors signal
185 strength, link quality and noise ratio..
186 * A plugin for Apple hardware sensors has been added.
187 * An option to compile collectd with different `step' and `hearbeat'
188 settings has been added. The size of RRAs is no longer static but
189 calculated based on the settings for `step' and `width'.
190 * The `ping' plugin can now be configured to use a certain TTL.
191 * A plugin to monitor the hardware sensors of Apple computers has been
193 * The plugins `cpu', `memory', `processes' and `traffic' have been
194 ported to Mach/Darwin (Mac OS X).
195 * The `log mode' has been contributed by Christophe Kalt. It writes
196 the data into text files rather than RRD files.
198 2006-04-09, Version 3.8.4
199 * Applied patch by Vincent Stehlé which improves the disk-name
200 resolution in the `hddtemp' plugin for Linux systems.
202 2006-04-02, Version 3.8.3
203 * Applied a patch by James Byers: The MySQL plugin was not working
204 with MySQL 5.0.2 or later.
206 2006-03-14, Version 3.8.2
207 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
208 the GNU libc, because it points to `/etc/fstab' rather than
211 2006-03-13, Version 3.8.1
212 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
213 * Fixes in the debian `postinst' and `init.d' scripts.
215 2006-03-09, Version 3.8.0
216 * The `ping' plugin no longer uses `libping' but a self written
217 library named `liboping'. With this library it's possible to ping
218 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
220 2006-02-18, Version 3.7.2
221 * A simple bug in the `battery' plugin has been fixed. It should now
222 work with ACPI based batteries as well. Thankt to Sebastian for
224 * Fixing a bug that prevented collectd to be built without librrd.
225 Thanks to Werner Heuser for reporting it.
227 2006-02-04, Version 3.7.1
228 * The new network code has been improved to build with older versions
230 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
231 to Tommie Gannert for this patch.
233 2006-01-30, Version 3.7.0
234 * The `battery' plugin has been added. It collects information about
236 * The MySQL plugin has been improved: It now writes two more RRD
237 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
238 * The `cpufreq' plugin now reads another file since the file it did
239 read so far causes much overhead in the kernel. Also, you need root
240 to read the old file, but not to read the new one.
241 * The `hddtemp' plugin can now be configured to connect to another
242 address and/or port than localhost.
243 * The `df' plugin now prefers `statvfs' over `statfs'.
244 * The network code has been rewritten. collectd now supports unicast
245 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
246 be set in the configfile.
248 2006-01-24, Version 3.6.2
249 * Due to a bug in the configfile handling collectd wouldn't start in
250 client mode. This released fixes this.
252 2006-01-20, Version 3.6.1
253 * Due to a bug in `configure.in' all modules and the binary were
254 linked against `libmysqlclient'. This issue is solved by this
257 2006-01-17, Version 3.6.0
258 * A config file has been added. This allows for loading only specific
260 * A `df' plugin has been added.
261 * A `mysql' plugin has been added.
262 * The `ping' plugin doesn't entirely give up hope when a socket error
263 occured, but will back of and increase the intervals between tries.
265 2006-01-21, Version 3.5.2
266 * Fixed yet another bug in the signal handling.. Stupid typo..
267 * Improved the ping plugin to not give up on socket errors (backport
270 2005-12-18, Version 3.5.1
271 * The PID-file is now deleted correctly when shutting down the daemon.
272 * SIGINT and SIGTERM are now handled correctly.
274 2005-12-16, Version 3.5.0 (Revision 326)
275 * A bug in the `load' module under Solaris has been fixed.
276 * The `users' module has been contributed by Sebastian Harl. It counts
277 currently logged in users.
278 * The CPU module now works under FreeBSD without the use of
279 `libstatgrab', however SMP support is missing.
280 * The default directories for the RRD files and the PID file now
281 depend on the compile time setting of `localstatedir'.
283 2005-11-15, Version 3.4.0 (Revision 236)
284 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
285 from gentoo's bugzilla for writing the patch.
286 * The build dependency for librrd has been removed. Binaries built
287 without librrd are client-only and will multicast their value as
288 with the `-c' argument.
289 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
290 * The newly introduced `-f' switch prevents daemon initialization
291 (forking, closing standard filehandles, etc.) Thanks to Alvaro
292 Barcellos for this patch.
294 2005-11-04, Version 3.3.0 (Revision 216)
295 * New modules have been added:
296 - `serial', for monitoring traffic on the serial interfaces
297 - `nfs', for graphing NFS procedure calls
298 - `tape', traffic from/to tape devices
299 * The the memory.rrd now accepts more than 4Gig of memory.
301 2005-10-26, Version 3.2.0 (Revision 200)
302 * Support for graphing the processes has been added (thanks to Lyonel

307 * Problems with the spec file have been fixed.
309 2005-10-16, Version 3.1.0 (Revision 194)
310 * Added the `setsid' syscall to the startup code.
311 * Support for hddtemp has been added (thanks to Vincent Stehlé)
313 2005-09-30, Version 3.0.0 (Revision 184)
314 * The ability to send/receive data to/from the network (think
315 multicast) has been added.
316 * Modules have been split up into shared libraries can be loaded at
317 runtime. The biggest advantage is that the core program doesn't need
318 to be linked against an external library.
319 * A patch by George Kargiotakis has been applied: It fixes the sensors
320 behaviour then more than one sensor is being queried.
322 2005-09-16, Version 2.1.0 (Revision 172)
323 * A module for swap statistics has been added.
325 2005-09-09, Version 2.0.0 (Revision 135)
326 * Filenames can no longer be configured at program startup. The only
327 options as of this version are the directory and ping hosts.
328 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
329 Soft-IRQ statistics are added to `System'.
330 * Diskstats now collect read and write bytes, not sectors.
331 * Ping statistics can now be collected for more than one host. There
332 is no default any more: If no host is given no host will be pinged.
333 * A self-written patch for libping has been applied so it builds
336 2005-09-01, Version 1.8.1 (Revision 123)
337 * Much improved configure-script: libraries and features may now be
339 * More detailed warnings/error messages when RRD update failes.
341 2005-08-29, Version 1.8.0:
342 * Support for collecting disk statistics under Solaris.
344 2005-08-25, Version 1.7.0:
345 * Support for libstatgrab[1] for load, memory usage and network
346 traffic. CPU- and disk-usage are not (yet) supported, since
347 libstatgrab returns insufficient information. I will contact the
349 * Improved the CPU-initialization code for Solaris. Apparently CPUs
350 aren't neccessarily counted linear which is now handled correctly.
351 [1]: http://www.i-scream.org/libstatgrab/
353 2005-08-21, Version 1.6.0:
354 * Basic support for Solaris: System load and cpu-usage can be
355 collected unter Solaris, too. Other stats will follow later.
356 * Many fixes in the autoconf-script
357 * Collection/Museum scripts have been added unter contrib/museum
358 * collectd may now be started in unprivileged mode, though ping
359 statistics will not work.
361 2005-07-17, Version 1.5.1:
362 * Diskstats-RRDs now use major/minor for naming. Some systems have
363 weird strings as disk-names..
365 2005-07-17, Version 1.5:
366 * A new module, diskstats, has been added. It collects information
367 about the disks and partitions.
369 2005-07-11, Version 1.4.2:
370 * The meminfo mofule has been changed to work with more platforms
371 and/or kernel versions.
373 2005-07-10, Version 1.4.1: Correct traffic stats
374 * The traffic rrd-file is now created with DS-type `COUNTER' which I
375 forgot to correct when I changed that module.
377 2005-07-09, Version 1.4: More traffic stats
378 * Traffic is now collected for all interfaces that can be found
379 * Temperature-statistics are read from lm-sensors if available
381 2005-07-08, Version 1.3: CPU stats
382 * Collecting CPU statistics now
384 2004-07-12, Version 1.2: Using syslog
385 * collectd is now using the syslog facility to report errors, warnings
387 * The default directory is now /var/db/collectd
389 2004-07-10, Version 1.1: Minor changes
390 * Nothing really usefull to say ;)
392 2004-07-09, Version 1.0: Initial Version
393 * The following modules are provided:
