1 2007-06-18, 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.
5 2007-06-12, Version 4.0.2
6 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
7 they're given in numerically form.
9 2007-06-07, Version 4.0.1
10 * iptables plugin: A bug in the configuration routine has been fixed.
11 Setting a comment in the configfile will no longer cause a
14 2007-06-03, Version 4.0.0
15 * collectd: The plugin-infrastructure has been changed to allow for
16 more types of plugins, namely `write' and `log' plugins.
17 * collectd: The read-function has been changed to read many plugins in
18 parallel, using threads. Thus, plugins generally need to use
19 thread-safe functions from now on.
20 * collectd: The '-t' command line options allows to perform syntax tests
21 of the configuration file and exit immediately.
22 * csv plugin: The new `csv' plugin handles output to `comma separated
24 * rrdtool plugin: The new `rrdtool' plugin handles output to
25 RRD-files. Data can be cached to combine multiple updates into one
26 write to increase IO-performance.
27 * network plugin: The new `network' plugin handles IO via the network.
28 It implements a different, much more extensible protocol which can
29 combine many values in one packet, decreasing the number of UDP-
30 packets being sent. It can read from and send to the network and
31 with the appropriate configuration even forward packets to other
33 * unixsock plugin: The new `unixsock' plugin provides an interface to
34 communicate with the daemon while it is running. Right now the
35 commands `GETVAL' and `PUTVAL' are implemented, but more are to
37 * perl plugin: The new `perl' plugin allows you to write extensions
38 for collectd in the scripting-language Perl.
39 * logfile plugin: The new `logfile' plugin writes logmessages to files
41 * syslog plugin: The new `syslog' plugin sends logmessages to the
42 system's syslog daemon.
43 * entropy plugin: The new `entropy' plugin collects the amount of
44 entropy currently being available to the system.
45 * exec plugin: The new `exec' plugin forks child processes and reads
46 back values provided by the forked processes.
47 * iptables plugin: The new `iptables' plugin reads counters from
48 iptables rules. Thanks to Sjoerd van der Berg for contributing this
50 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
51 to Peter Holik for contributing this plugin.
52 * nut plugin: The new `nut' plugin connects the upsd of the `network
53 ups tools' and reads information about the connected UPS.
54 * apache plugin: Support for lighttpd's `BusyServers' (aka.
55 connections) field was added by Florent Monbillard.
56 * collectd-nagios: The new `collectd-nagios' binary queries values
57 from collectd, parses them and exits according to Nagios-standards.
58 * manpages: The manpages have been improved a lot.
60 2007-05-29, Version 3.11.5
61 * configure: Added `AC_SYS_LARGEFILE' for LFS.
62 * ntpd plugin: Fix a potential buffer overflow.
63 * processes plugin: Fix a bug when run under Linux 2.4. All processes
64 were accounted as `zombies'.
66 2007-04-10, Version 3.11.4
67 * dns plugin: Change the order of includes to make the plugin compile
70 2007-03-30, Version 3.11.3
71 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
72 of the unused `COLLECT_KSTAT'.
74 2007-02-11, Version 3.11.2
75 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
76 NULL-pointer may have been passed to `printf' which causes a
77 segfault with some libcs.
79 2007-02-10, Version 3.11.1
80 * df plugin: Some wrong defines have been fixed so the plugin works
82 * dns plugin: The usage of a struct has been fixed to work with
84 * processes plugin: Some missing defines have been added so the plugin
85 compiles cleanly under FreeBSD and presumably other UNIXes.
87 2006-12-22, Version 3.11.0
88 * collectd: The new command line option `-P' makes it easier for
89 distributors to change the location of PID-files.
90 * collectd: The daemon shuts down faster now which makes it easier to
91 write init.d-scripts for it.
92 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
93 caused problems every now and then.
94 * df plugin: New config options allow to ignore certain mountpoints,
95 filesystem types or devices.
96 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
97 and interprets it. It collects traffic as well as qtype, opcode and
99 * email plugin: Sebastian Harl has contributed this plugin which
100 counts received mails in categories (e. g. ham, spam, virus), spam
101 score (as given by SpamAssassin) and check types.
102 * mbmon plugin: Flavio Stanchina has contributed this plugin which
103 uses `mbmon' to gather information from sensors on the motherboard.
104 * processes plugin: Collect detailed statistics for configured
105 processes, that's process and thread count, CPU usage, resident
106 segment size and pagefaults.
107 * multimeter plugin: Peter Holik contributed a new plugin which
109 * sensors plugin: Lubos Stanek has put much effort into improving this
110 plugin, including `extended naming', collection of voltage values
111 and the possibility to ignore certain values.
113 2006-12-21, Version 3.10.4
114 * Max Kellermann has identified a bug in the server routine: When
115 opening a socket fails the daemon will (re)try opening the socket in
116 an endless loop, ultimately leading to a `EMFILE' error.
118 2006-11-04, Version 3.10.3
119 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
120 ntpd's reply was sent in more than one packet, the buffer size was
121 calculated incorrectly, resulting in the reading of uninitialized or
124 2006-11-01, Version 3.10.2
125 * The sample config file has been improved.
126 * Errors in the manpages have been corrected.
127 * The ping-plugin now adds hosts during initialization, not during
128 startup. This speeds up starup when no network connectivity is
129 available. Also, the hosts are being added later when the network is
131 * Improved BSD-support for the df-plugin.
132 * Fixed syntax errors in the swap-plugin for Mac OS X.
133 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
135 * Don't disable the mysql-plugin if connecting to the database fails
136 during initialization. Instead, try again in increasing intervals.
138 2006-07-19, Version 3.10.1
139 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
140 the apcups cannot be reached, unconnected sockets will pile up and
141 eventually lead to `Too many open files' errors.
143 2006-07-09, Version 3.10.0
144 * The `disk' plugin has been ported to Darwin.
145 * The `battery' plugin should work on many Apple computers now.
146 * The `traffic' plugin can now ignore certain interfaces. Also,
147 statistics for sent/received packets and errors have been added.
148 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
149 to Anthony Gialluca for contributing this plugin and providing me
150 with a test environment :)
151 * A plugin for moniroting an NTP instance and the local clock drift
154 2006-06-25, Version 3.9.4
155 * The Solaris code in the `swap' plugin has been changed to reflect
156 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
158 * The debugging system has been fixed to work with the Sun libc.
159 * When built without librrd the variable `operating_mode' could be
160 uninitialized. Thanks to David Elliot for reporting the bug.
162 2006-06-01, Version 3.9.3
163 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
164 operating systems also profit from the changes, but I wasn't able to
166 * Changed the build system to find the netinet-includes under FreeBSD
167 and therefore successfully build the `liboping' library there.
169 2006-05-09, Version 3.9.2
170 * Applied a patch to the `liboping' library. Due to a bug in the
171 sequence checking the `ping' plugin stopped working after
172 approximately 7.6 days.
174 2006-05-09, Version 3.8.5
175 * Applied a patch to the `liboping' library. Due to a bug in the
176 sequence checking the `ping' plugin stopped working after
177 approximately 7.6 days.
179 2006-04-21, Version 3.9.1
180 * Build issues with Solaris and possible other architectures have been
182 * Problems when building the `apache'-plugin without `libcurl' have
184 * A bug in the `ping' plugin has been fixed. Sorry folks.
186 2006-04-02, Version 3.9.0
187 * A plugin to monitor the Apache webserver has been added.
188 <http://httpd.apache.org/>
189 * A plugin to collect statistics about virtual servers using VServer.
190 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
192 * A plugin for wireless LAN cards has been added. It monitors signal
193 strength, link quality and noise ratio..
194 * A plugin for Apple hardware sensors has been added.
195 * An option to compile collectd with different `step' and `hearbeat'
196 settings has been added. The size of RRAs is no longer static but
197 calculated based on the settings for `step' and `width'.
198 * The `ping' plugin can now be configured to use a certain TTL.
199 * A plugin to monitor the hardware sensors of Apple computers has been
201 * The plugins `cpu', `memory', `processes' and `traffic' have been
202 ported to Mach/Darwin (Mac OS X).
203 * The `log mode' has been contributed by Christophe Kalt. It writes
204 the data into text files rather than RRD files.
206 2006-04-09, Version 3.8.4
207 * Applied patch by Vincent Stehlé which improves the disk-name
208 resolution in the `hddtemp' plugin for Linux systems.
210 2006-04-02, Version 3.8.3
211 * Applied a patch by James Byers: The MySQL plugin was not working
212 with MySQL 5.0.2 or later.
214 2006-03-14, Version 3.8.2
215 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
216 the GNU libc, because it points to `/etc/fstab' rather than
219 2006-03-13, Version 3.8.1
220 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
221 * Fixes in the debian `postinst' and `init.d' scripts.
223 2006-03-09, Version 3.8.0
224 * The `ping' plugin no longer uses `libping' but a self written
225 library named `liboping'. With this library it's possible to ping
226 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
228 2006-02-18, Version 3.7.2
229 * A simple bug in the `battery' plugin has been fixed. It should now
230 work with ACPI based batteries as well. Thankt to Sebastian for
232 * Fixing a bug that prevented collectd to be built without librrd.
233 Thanks to Werner Heuser for reporting it.
235 2006-02-04, Version 3.7.1
236 * The new network code has been improved to build with older versions

241 2006-01-30, Version 3.7.0
242 * The `battery' plugin has been added. It collects information about
244 * The MySQL plugin has been improved: It now writes two more RRD
245 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
246 * The `cpufreq' plugin now reads another file since the file it did
247 read so far causes much overhead in the kernel. Also, you need root
248 to read the old file, but not to read the new one.
249 * The `hddtemp' plugin can now be configured to connect to another
250 address and/or port than localhost.
251 * The `df' plugin now prefers `statvfs' over `statfs'.
252 * The network code has been rewritten. collectd now supports unicast
253 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
254 be set in the configfile.
256 2006-01-24, Version 3.6.2
257 * Due to a bug in the configfile handling collectd wouldn't start in
258 client mode. This released fixes this.
260 2006-01-20, Version 3.6.1
261 * Due to a bug in `configure.in' all modules and the binary were
262 linked against `libmysqlclient'. This issue is solved by this
265 2006-01-17, Version 3.6.0
266 * A config file has been added. This allows for loading only specific
268 * A `df' plugin has been added.
269 * A `mysql' plugin has been added.
270 * The `ping' plugin doesn't entirely give up hope when a socket error
271 occured, but will back of and increase the intervals between tries.
273 2006-01-21, Version 3.5.2
274 * Fixed yet another bug in the signal handling.. Stupid typo..
275 * Improved the ping plugin to not give up on socket errors (backport
278 2005-12-18, Version 3.5.1
279 * The PID-file is now deleted correctly when shutting down the daemon.
280 * SIGINT and SIGTERM are now handled correctly.
282 2005-12-16, Version 3.5.0 (Revision 326)
283 * A bug in the `load' module under Solaris has been fixed.
284 * The `users' module has been contributed by Sebastian Harl. It counts
285 currently logged in users.
286 * The CPU module now works under FreeBSD without the use of
287 `libstatgrab', however SMP support is missing.
288 * The default directories for the RRD files and the PID file now
289 depend on the compile time setting of `localstatedir'.
291 2005-11-15, Version 3.4.0 (Revision 236)
292 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
293 from gentoo's bugzilla for writing the patch.
294 * The build dependency for librrd has been removed. Binaries built
295 without librrd are client-only and will multicast their value as
296 with the `-c' argument.
297 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
298 * The newly introduced `-f' switch prevents daemon initialization
299 (forking, closing standard filehandles, etc.) Thanks to Alvaro
300 Barcellos for this patch.
302 2005-11-04, Version 3.3.0 (Revision 216)
303 * New modules have been added:
304 - `serial', for monitoring traffic on the serial interfaces
305 - `nfs', for graphing NFS procedure calls
306 - `tape', traffic from/to tape devices
307 * The the memory.rrd now accepts more than 4Gig of memory.
309 2005-10-26, Version 3.2.0 (Revision 200)
310 * Support for graphing the processes has been added (thanks to Lyonel

313 between polls up to one day.
314 * The init.d files have been improved.
315 * Problems with the spec file have been fixed.
317 2005-10-16, Version 3.1.0 (Revision 194)
318 * Added the `setsid' syscall to the startup code.
319 * Support for hddtemp has been added (thanks to Vincent Stehlé)
321 2005-09-30, Version 3.0.0 (Revision 184)
322 * The ability to send/receive data to/from the network (think
323 multicast) has been added.
324 * Modules have been split up into shared libraries can be loaded at
325 runtime. The biggest advantage is that the core program doesn't need
326 to be linked against an external library.
327 * A patch by George Kargiotakis has been applied: It fixes the sensors
328 behaviour then more than one sensor is being queried.
330 2005-09-16, Version 2.1.0 (Revision 172)
331 * A module for swap statistics has been added.
333 2005-09-09, Version 2.0.0 (Revision 135)
334 * Filenames can no longer be configured at program startup. The only
335 options as of this version are the directory and ping hosts.
336 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
337 Soft-IRQ statistics are added to `System'.
338 * Diskstats now collect read and write bytes, not sectors.
339 * Ping statistics can now be collected for more than one host. There
340 is no default any more: If no host is given no host will be pinged.
341 * A self-written patch for libping has been applied so it builds
344 2005-09-01, Version 1.8.1 (Revision 123)
345 * Much improved configure-script: libraries and features may now be
347 * More detailed warnings/error messages when RRD update failes.
349 2005-08-29, Version 1.8.0:
350 * Support for collecting disk statistics under Solaris.
352 2005-08-25, Version 1.7.0:
353 * Support for libstatgrab[1] for load, memory usage and network
354 traffic. CPU- and disk-usage are not (yet) supported, since
355 libstatgrab returns insufficient information. I will contact the
357 * Improved the CPU-initialization code for Solaris. Apparently CPUs
358 aren't neccessarily counted linear which is now handled correctly.
359 [1]: http://www.i-scream.org/libstatgrab/
361 2005-08-21, Version 1.6.0:
362 * Basic support for Solaris: System load and cpu-usage can be
363 collected unter Solaris, too. Other stats will follow later.
364 * Many fixes in the autoconf-script
365 * Collection/Museum scripts have been added unter contrib/museum
366 * collectd may now be started in unprivileged mode, though ping
367 statistics will not work.
369 2005-07-17, Version 1.5.1:
370 * Diskstats-RRDs now use major/minor for naming. Some systems have
371 weird strings as disk-names..
373 2005-07-17, Version 1.5:
374 * A new module, diskstats, has been added. It collects information
375 about the disks and partitions.
377 2005-07-11, Version 1.4.2:
378 * The meminfo mofule has been changed to work with more platforms
379 and/or kernel versions.
381 2005-07-10, Version 1.4.1: Correct traffic stats
382 * The traffic rrd-file is now created with DS-type `COUNTER' which I
383 forgot to correct when I changed that module.
385 2005-07-09, Version 1.4: More traffic stats
386 * Traffic is now collected for all interfaces that can be found
387 * Temperature-statistics are read from lm-sensors if available
389 2005-07-08, Version 1.3: CPU stats
390 * Collecting CPU statistics now
392 2004-07-12, Version 1.2: Using syslog
393 * collectd is now using the syslog facility to report errors, warnings
395 * The default directory is now /var/db/collectd
397 2004-07-10, Version 1.1: Minor changes
398 * Nothing really usefull to say ;)
400 2004-07-09, Version 1.0: Initial Version
401 * The following modules are provided:
