1 2007-04-02, Version 4.0.0
2 * collectd: The plugin-infrastructure has been changed to allow for
3 more types of plugins, namely `write' and `log' plugins.
4 * collectd: The read-function has been changed to read many plugins in
5 parallel, using threads. Thus, plugins generally need to use
6 thread-safe functions from now on.
7 * collectd: The '-t' command line options allows to perform syntax tests
8 of the configuration file and exit immediately.
9 * csv plugin: The new `csv' plugin handles output to `comma separated
11 * rrdtool plugin: The new `rrdtool' plugin handles output to
12 RRD-files. Data can be cached to combine multiple updates into one
13 write to increase IO-performance.
14 * network plugin: The new `network' plugin handles IO via the network.
15 It implements a different, much more extensible protocol which can
16 combine many values in one packet, decreasing the number of UDP-
17 packets being sent. It can read from and send to the network and
18 with the appropriate configuration even forward packets to other
20 * unixsock plugin: The new `unixsock' plugin provides an interface to
21 communicate with the daemon while it is running. Right now the
22 commands `GETVAL' and `PUTVAL' are implemented, but more are to
24 * perl plugin: The new `perl' plugin allows you to write extensions
25 for collectd in the scripting-language Perl.
26 * logfile plugin: The new `logfile' plugin writes logmessages to files
28 * syslog plugin: The new `syslog' plugin sends logmessages to the
29 system's syslog daemon.
30 * entropy plugin: The new `entropy' plugin collects the amount of
31 entropy currently being available to the system.
32 * exec plugin: The new `exec' plugin forks child processes and reads
33 back values provided by the forked processes.
34 * iptables plugin: The new `iptables' plugin reads counters from
35 iptables rules. Thanks to Sjoerd van der Berg for contributing this
37 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
38 to Peter Holik for contributing this plugin.
39 * nut plugin: The new `nut' plugin connects the upsd of the `network
40 ups tools' and reads information about the connected UPS.
41 * apache plugin: Support for lighttpd's `BusyServers' (aka.
42 connections) field was added by Florent Monbillard.
43 * collectd-nagios: The new `collectd-nagios' binary queries values
44 from collectd, parses them and exits according to Nagios-standards.
46 2007-05-29, Version 3.11.5
47 * configure: Added `AC_SYS_LARGEFILE' for LFS.
48 * ntpd plugin: Fix a potential buffer overflow.
49 * processes plugin: Fix a bug when run under Linux 2.4. All processes
50 were accounted as `zombies'.
52 2007-04-10, Version 3.11.4
53 * dns plugin: Change the order of includes to make the plugin compile
56 2007-03-30, Version 3.11.3
57 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
58 of the unused `COLLECT_KSTAT'.
60 2007-02-11, Version 3.11.2
61 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
62 NULL-pointer may have been passed to `printf' which causes a
63 segfault with some libcs.
65 2007-02-10, Version 3.11.1
66 * df plugin: Some wrong defines have been fixed so the plugin works
68 * dns plugin: The usage of a struct has been fixed to work with
70 * processes plugin: Some missing defines have been added so the plugin
71 compiles cleanly under FreeBSD and presumably other UNIXes.
73 2006-12-22, Version 3.11.0
74 * collectd: The new command line option `-P' makes it easier for
75 distributors to change the location of PID-files.
76 * collectd: The daemon shuts down faster now which makes it easier to
77 write init.d-scripts for it.
78 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
79 caused problems every now and then.
80 * df plugin: New config options allow to ignore certain mountpoints,
81 filesystem types or devices.
82 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
83 and interprets it. It collects traffic as well as qtype, opcode and
85 * email plugin: Sebastian Harl has contributed this plugin which
86 counts received mails in categories (e. g. ham, spam, virus), spam
87 score (as given by SpamAssassin) and check types.
88 * mbmon plugin: Flavio Stanchina has contributed this plugin which
89 uses `mbmon' to gather information from sensors on the motherboard.
90 * processes plugin: Collect detailed statistics for configured
91 processes, that's process and thread count, CPU usage, resident
92 segment size and pagefaults.
93 * multimeter plugin: Peter Holik contributed a new plugin which
95 * sensors plugin: Lubos Stanek has put much effort into improving this
96 plugin, including `extended naming', collection of voltage values
97 and the possibility to ignore certain values.
99 2006-12-21, Version 3.10.4
100 * Max Kellermann has identified a bug in the server routine: When
101 opening a socket fails the daemon will (re)try opening the socket in
102 an endless loop, ultimately leading to a `EMFILE' error.
104 2006-11-04, Version 3.10.3
105 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
106 ntpd's reply was sent in more than one packet, the buffer size was
107 calculated incorrectly, resulting in the reading of uninitialized or
110 2006-11-01, Version 3.10.2
111 * The sample config file has been improved.
112 * Errors in the manpages have been corrected.
113 * The ping-plugin now adds hosts during initialization, not during
114 startup. This speeds up starup when no network connectivity is
115 available. Also, the hosts are being added later when the network is
117 * Improved BSD-support for the df-plugin.
118 * Fixed syntax errors in the swap-plugin for Mac OS X.
119 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
121 * Don't disable the mysql-plugin if connecting to the database fails
122 during initialization. Instead, try again in increasing intervals.
124 2006-07-19, Version 3.10.1
125 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
126 the apcups cannot be reached, unconnected sockets will pile up and
127 eventually lead to `Too many open files' errors.
129 2006-07-09, Version 3.10.0
130 * The `disk' plugin has been ported to Darwin.
131 * The `battery' plugin should work on many Apple computers now.
132 * The `traffic' plugin can now ignore certain interfaces. Also,
133 statistics for sent/received packets and errors have been added.
134 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
135 to Anthony Gialluca for contributing this plugin and providing me
136 with a test environment :)
137 * A plugin for moniroting an NTP instance and the local clock drift
140 2006-06-25, Version 3.9.4
141 * The Solaris code in the `swap' plugin has been changed to reflect
142 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
144 * The debugging system has been fixed to work with the Sun libc.
145 * When built without librrd the variable `operating_mode' could be
146 uninitialized. Thanks to David Elliot for reporting the bug.
148 2006-06-01, Version 3.9.3
149 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
150 operating systems also profit from the changes, but I wasn't able to
152 * Changed the build system to find the netinet-includes under FreeBSD
153 and therefore successfully build the `liboping' library there.
155 2006-05-09, Version 3.9.2
156 * Applied a patch to the `liboping' library. Due to a bug in the
157 sequence checking the `ping' plugin stopped working after
158 approximately 7.6 days.
160 2006-05-09, Version 3.8.5
161 * Applied a patch to the `liboping' library. Due to a bug in the
162 sequence checking the `ping' plugin stopped working after
163 approximately 7.6 days.
165 2006-04-21, Version 3.9.1
166 * Build issues with Solaris and possible other architectures have been
168 * Problems when building the `apache'-plugin without `libcurl' have
170 * A bug in the `ping' plugin has been fixed. Sorry folks.
172 2006-04-02, Version 3.9.0
173 * A plugin to monitor the Apache webserver has been added.
174 <http://httpd.apache.org/>
175 * A plugin to collect statistics about virtual servers using VServer.
176 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
178 * A plugin for wireless LAN cards has been added. It monitors signal
179 strength, link quality and noise ratio..
180 * A plugin for Apple hardware sensors has been added.
181 * An option to compile collectd with different `step' and `hearbeat'
182 settings has been added. The size of RRAs is no longer static but
183 calculated based on the settings for `step' and `width'.
184 * The `ping' plugin can now be configured to use a certain TTL.
185 * A plugin to monitor the hardware sensors of Apple computers has been
187 * The plugins `cpu', `memory', `processes' and `traffic' have been
188 ported to Mach/Darwin (Mac OS X).
189 * The `log mode' has been contributed by Christophe Kalt. It writes
190 the data into text files rather than RRD files.
192 2006-04-09, Version 3.8.4
193 * Applied patch by Vincent Stehlé which improves the disk-name
194 resolution in the `hddtemp' plugin for Linux systems.
196 2006-04-02, Version 3.8.3
197 * Applied a patch by James Byers: The MySQL plugin was not working
198 with MySQL 5.0.2 or later.
200 2006-03-14, Version 3.8.2
201 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
202 the GNU libc, because it points to `/etc/fstab' rather than
205 2006-03-13, Version 3.8.1
206 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
207 * Fixes in the debian `postinst' and `init.d' scripts.
209 2006-03-09, Version 3.8.0
210 * The `ping' plugin no longer uses `libping' but a self written
211 library named `liboping'. With this library it's possible to ping
212 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
214 2006-02-18, Version 3.7.2
215 * A simple bug in the `battery' plugin has been fixed. It should now
216 work with ACPI based batteries as well. Thankt to Sebastian for
218 * Fixing a bug that prevented collectd to be built without librrd.
219 Thanks to Werner Heuser for reporting it.
221 2006-02-04, Version 3.7.1
222 * The new network code has been improved to build with older versions
224 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
225 to Tommie Gannert for this patch.
227 2006-01-30, Version 3.7.0
228 * The `battery' plugin has been added. It collects information about
230 * The MySQL plugin has been improved: It now writes two more RRD
231 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
232 * The `cpufreq' plugin now reads another file since the file it did
233 read so far causes much overhead in the kernel. Also, you need root
234 to read the old file, but not to read the new one.
235 * The `hddtemp' plugin can now be configured to connect to another
236 address and/or port than localhost.
237 * The `df' plugin now prefers `statvfs' over `statfs'.
238 * The network code has been rewritten. collectd now supports unicast
239 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
240 be set in the configfile.
242 2006-01-24, Version 3.6.2
243 * Due to a bug in the configfile handling collectd wouldn't start in
244 client mode. This released fixes this.
246 2006-01-20, Version 3.6.1
247 * Due to a bug in `configure.in' all modules and the binary were
248 linked against `libmysqlclient'. This issue is solved by this
251 2006-01-17, Version 3.6.0
252 * A config file has been added. This allows for loading only specific
254 * A `df' plugin has been added.
255 * A `mysql' plugin has been added.
256 * The `ping' plugin doesn't entirely give up hope when a socket error
257 occured, but will back of and increase the intervals between tries.
259 2006-01-21, Version 3.5.2
260 * Fixed yet another bug in the signal handling.. Stupid typo..
261 * Improved the ping plugin to not give up on socket errors (backport
264 2005-12-18, Version 3.5.1
265 * The PID-file is now deleted correctly when shutting down the daemon.
266 * SIGINT and SIGTERM are now handled correctly.
268 2005-12-16, Version 3.5.0 (Revision 326)
269 * A bug in the `load' module under Solaris has been fixed.
270 * The `users' module has been contributed by Sebastian Harl. It counts
271 currently logged in users.
272 * The CPU module now works under FreeBSD without the use of
273 `libstatgrab', however SMP support is missing.
274 * The default directories for the RRD files and the PID file now
275 depend on the compile time setting of `localstatedir'.
277 2005-11-15, Version 3.4.0 (Revision 236)
278 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
279 from gentoo's bugzilla for writing the patch.
280 * The build dependency for librrd has been removed. Binaries built
281 without librrd are client-only and will multicast their value as
282 with the `-c' argument.
283 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
284 * The newly introduced `-f' switch prevents daemon initialization
285 (forking, closing standard filehandles, etc.) Thanks to Alvaro
286 Barcellos for this patch.
288 2005-11-04, Version 3.3.0 (Revision 216)
289 * New modules have been added:
290 - `serial', for monitoring traffic on the serial interfaces
291 - `nfs', for graphing NFS procedure calls
292 - `tape', traffic from/to tape devices
293 * The the memory.rrd now accepts more than 4Gig of memory.
295 2005-10-26, Version 3.2.0 (Revision 200)
296 * Support for graphing the processes has been added (thanks to Lyonel
298 * If reading from hddtemp failes collectd will increase the time
299 between polls up to one day.
300 * The init.d files have been improved.
301 * Problems with the spec file have been fixed.
303 2005-10-16, Version 3.1.0 (Revision 194)
304 * Added the `setsid' syscall to the startup code.
305 * Support for hddtemp has been added (thanks to Vincent Stehlé)
307 2005-09-30, Version 3.0.0 (Revision 184)
308 * The ability to send/receive data to/from the network (think
309 multicast) has been added.
310 * Modules have been split up into shared libraries can be loaded at
311 runtime. The biggest advantage is that the core program doesn't need
312 to be linked against an external library.
313 * A patch by George Kargiotakis has been applied: It fixes the sensors
314 behaviour then more than one sensor is being queried.
316 2005-09-16, Version 2.1.0 (Revision 172)
317 * A module for swap statistics has been added.
319 2005-09-09, Version 2.0.0 (Revision 135)
320 * Filenames can no longer be configured at program startup. The only
321 options as of this version are the directory and ping hosts.
322 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
323 Soft-IRQ statistics are added to `System'.
324 * Diskstats now collect read and write bytes, not sectors.
325 * Ping statistics can now be collected for more than one host. There
326 is no default any more: If no host is given no host will be pinged.
327 * A self-written patch for libping has been applied so it builds
330 2005-09-01, Version 1.8.1 (Revision 123)
331 * Much improved configure-script: libraries and features may now be
333 * More detailed warnings/error messages when RRD update failes.
335 2005-08-29, Version 1.8.0:
336 * Support for collecting disk statistics under Solaris.
338 2005-08-25, Version 1.7.0:
339 * Support for libstatgrab[1] for load, memory usage and network
340 traffic. CPU- and disk-usage are not (yet) supported, since
341 libstatgrab returns insufficient information. I will contact the
343 * Improved the CPU-initialization code for Solaris. Apparently CPUs
344 aren't neccessarily counted linear which is now handled correctly.
345 [1]: http://www.i-scream.org/libstatgrab/
347 2005-08-21, Version 1.6.0:
348 * Basic support for Solaris: System load and cpu-usage can be
349 collected unter Solaris, too. Other stats will follow later.
350 * Many fixes in the autoconf-script
351 * Collection/Museum scripts have been added unter contrib/museum
352 * collectd may now be started in unprivileged mode, though ping
353 statistics will not work.
355 2005-07-17, Version 1.5.1:
356 * Diskstats-RRDs now use major/minor for naming. Some systems have
357 weird strings as disk-names..
359 2005-07-17, Version 1.5:
360 * A new module, diskstats, has been added. It collects information
361 about the disks and partitions.
363 2005-07-11, Version 1.4.2:
364 * The meminfo mofule has been changed to work with more platforms
365 and/or kernel versions.
367 2005-07-10, Version 1.4.1: Correct traffic stats
368 * The traffic rrd-file is now created with DS-type `COUNTER' which I
369 forgot to correct when I changed that module.
371 2005-07-09, Version 1.4: More traffic stats
372 * Traffic is now collected for all interfaces that can be found
373 * Temperature-statistics are read from lm-sensors if available
375 2005-07-08, Version 1.3: CPU stats
376 * Collecting CPU statistics now
378 2004-07-12, Version 1.2: Using syslog
379 * collectd is now using the syslog facility to report errors, warnings
381 * The default directory is now /var/db/collectd
383 2004-07-10, Version 1.1: Minor changes
384 * Nothing really usefull to say ;)
386 2004-07-09, Version 1.0: Initial Version
387 * The following modules are provided:
projects / collectd.git / blob
