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 2007-04-10, Version 3.11.4
47 * dns plugin: Change the order of includes to make the plugin compile
50 2007-03-30, Version 3.11.3
51 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
52 of the unused `COLLECT_KSTAT'.
54 2007-02-11, Version 3.11.2
55 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
56 NULL-pointer may have been passed to `printf' which causes a
57 segfault with some libcs.
59 2007-02-10, Version 3.11.1
60 * df plugin: Some wrong defines have been fixed so the plugin works
62 * dns plugin: The usage of a struct has been fixed to work with
64 * processes plugin: Some missing defines have been added so the plugin
65 compiles cleanly under FreeBSD and presumably other UNIXes.
67 2006-12-22, Version 3.11.0
68 * collectd: The new command line option `-P' makes it easier for
69 distributors to change the location of PID-files.
70 * collectd: The daemon shuts down faster now which makes it easier to
71 write init.d-scripts for it.
72 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
73 caused problems every now and then.
74 * df plugin: New config options allow to ignore certain mountpoints,
75 filesystem types or devices.
76 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
77 and interprets it. It collects traffic as well as qtype, opcode and
79 * email plugin: Sebastian Harl has contributed this plugin which
80 counts received mails in categories (e. g. ham, spam, virus), spam
81 score (as given by SpamAssassin) and check types.
82 * mbmon plugin: Flavio Stanchina has contributed this plugin which
83 uses `mbmon' to gather information from sensors on the motherboard.
84 * processes plugin: Collect detailed statistics for configured
85 processes, that's process and thread count, CPU usage, resident
86 segment size and pagefaults.
87 * multimeter plugin: Peter Holik contributed a new plugin which
89 * sensors plugin: Lubos Stanek has put much effort into improving this
90 plugin, including `extended naming', collection of voltage values
91 and the possibility to ignore certain values.
93 2006-12-21, Version 3.10.4
94 * Max Kellermann has identified a bug in the server routine: When
95 opening a socket fails the daemon will (re)try opening the socket in
96 an endless loop, ultimately leading to a `EMFILE' error.
98 2006-11-04, Version 3.10.3
99 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
100 ntpd's reply was sent in more than one packet, the buffer size was
101 calculated incorrectly, resulting in the reading of uninitialized or
104 2006-11-01, Version 3.10.2
105 * The sample config file has been improved.
106 * Errors in the manpages have been corrected.
107 * The ping-plugin now adds hosts during initialization, not during
108 startup. This speeds up starup when no network connectivity is
109 available. Also, the hosts are being added later when the network is
111 * Improved BSD-support for the df-plugin.
112 * Fixed syntax errors in the swap-plugin for Mac OS X.
113 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
115 * Don't disable the mysql-plugin if connecting to the database fails
116 during initialization. Instead, try again in increasing intervals.
118 2006-07-19, Version 3.10.1
119 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
120 the apcups cannot be reached, unconnected sockets will pile up and
121 eventually lead to `Too many open files' errors.
123 2006-07-09, Version 3.10.0
124 * The `disk' plugin has been ported to Darwin.
125 * The `battery' plugin should work on many Apple computers now.
126 * The `traffic' plugin can now ignore certain interfaces. Also,
127 statistics for sent/received packets and errors have been added.
128 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
129 to Anthony Gialluca for contributing this plugin and providing me
130 with a test environment :)
131 * A plugin for moniroting an NTP instance and the local clock drift
134 2006-06-25, Version 3.9.4
135 * The Solaris code in the `swap' plugin has been changed to reflect
136 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
138 * The debugging system has been fixed to work with the Sun libc.
139 * When built without librrd the variable `operating_mode' could be
140 uninitialized. Thanks to David Elliot for reporting the bug.
142 2006-06-01, Version 3.9.3
143 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
144 operating systems also profit from the changes, but I wasn't able to
146 * Changed the build system to find the netinet-includes under FreeBSD
147 and therefore successfully build the `liboping' library there.
149 2006-05-09, Version 3.9.2
150 * Applied a patch to the `liboping' library. Due to a bug in the
151 sequence checking the `ping' plugin stopped working after
152 approximately 7.6 days.
154 2006-05-09, Version 3.8.5
155 * Applied a patch to the `liboping' library. Due to a bug in the
156 sequence checking the `ping' plugin stopped working after
157 approximately 7.6 days.
159 2006-04-21, Version 3.9.1
160 * Build issues with Solaris and possible other architectures have been
162 * Problems when building the `apache'-plugin without `libcurl' have
164 * A bug in the `ping' plugin has been fixed. Sorry folks.
166 2006-04-02, Version 3.9.0
167 * A plugin to monitor the Apache webserver has been added.
168 <http://httpd.apache.org/>
169 * A plugin to collect statistics about virtual servers using VServer.
170 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
172 * A plugin for wireless LAN cards has been added. It monitors signal
173 strength, link quality and noise ratio..
174 * A plugin for Apple hardware sensors has been added.
175 * An option to compile collectd with different `step' and `hearbeat'
176 settings has been added. The size of RRAs is no longer static but
177 calculated based on the settings for `step' and `width'.
178 * The `ping' plugin can now be configured to use a certain TTL.
179 * A plugin to monitor the hardware sensors of Apple computers has been
181 * The plugins `cpu', `memory', `processes' and `traffic' have been
182 ported to Mach/Darwin (Mac OS X).
183 * The `log mode' has been contributed by Christophe Kalt. It writes
184 the data into text files rather than RRD files.
186 2006-04-09, Version 3.8.4
187 * Applied patch by Vincent Stehlé which improves the disk-name
188 resolution in the `hddtemp' plugin for Linux systems.
190 2006-04-02, Version 3.8.3
191 * Applied a patch by James Byers: The MySQL plugin was not working
192 with MySQL 5.0.2 or later.
194 2006-03-14, Version 3.8.2
195 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
196 the GNU libc, because it points to `/etc/fstab' rather than
199 2006-03-13, Version 3.8.1
200 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
201 * Fixes in the debian `postinst' and `init.d' scripts.
203 2006-03-09, Version 3.8.0
204 * The `ping' plugin no longer uses `libping' but a self written
205 library named `liboping'. With this library it's possible to ping
206 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
208 2006-02-18, Version 3.7.2
209 * A simple bug in the `battery' plugin has been fixed. It should now
210 work with ACPI based batteries as well. Thankt to Sebastian for
212 * Fixing a bug that prevented collectd to be built without librrd.
213 Thanks to Werner Heuser for reporting it.
215 2006-02-04, Version 3.7.1
216 * The new network code has been improved to build with older versions
218 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
219 to Tommie Gannert for this patch.
221 2006-01-30, Version 3.7.0
222 * The `battery' plugin has been added. It collects information about
224 * The MySQL plugin has been improved: It now writes two more RRD
225 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
226 * The `cpufreq' plugin now reads another file since the file it did
227 read so far causes much overhead in the kernel. Also, you need root
228 to read the old file, but not to read the new one.
229 * The `hddtemp' plugin can now be configured to connect to another
230 address and/or port than localhost.
231 * The `df' plugin now prefers `statvfs' over `statfs'.
232 * The network code has been rewritten. collectd now supports unicast
233 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
234 be set in the configfile.
236 2006-01-24, Version 3.6.2
237 * Due to a bug in the configfile handling collectd wouldn't start in
238 client mode. This released fixes this.
240 2006-01-20, Version 3.6.1
241 * Due to a bug in `configure.in' all modules and the binary were
242 linked against `libmysqlclient'. This issue is solved by this
245 2006-01-17, Version 3.6.0
246 * A config file has been added. This allows for loading only specific
248 * A `df' plugin has been added.
249 * A `mysql' plugin has been added.
250 * The `ping' plugin doesn't entirely give up hope when a socket error
251 occured, but will back of and increase the intervals between tries.
253 2006-01-21, Version 3.5.2
254 * Fixed yet another bug in the signal handling.. Stupid typo..
255 * Improved the ping plugin to not give up on socket errors (backport
258 2005-12-18, Version 3.5.1
259 * The PID-file is now deleted correctly when shutting down the daemon.
260 * SIGINT and SIGTERM are now handled correctly.
262 2005-12-16, Version 3.5.0 (Revision 326)
263 * A bug in the `load' module under Solaris has been fixed.
264 * The `users' module has been contributed by Sebastian Harl. It counts
265 currently logged in users.
266 * The CPU module now works under FreeBSD without the use of
267 `libstatgrab', however SMP support is missing.
268 * The default directories for the RRD files and the PID file now
269 depend on the compile time setting of `localstatedir'.
271 2005-11-15, Version 3.4.0 (Revision 236)
272 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
273 from gentoo's bugzilla for writing the patch.
274 * The build dependency for librrd has been removed. Binaries built
275 without librrd are client-only and will multicast their value as
276 with the `-c' argument.
277 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
278 * The newly introduced `-f' switch prevents daemon initialization
279 (forking, closing standard filehandles, etc.) Thanks to Alvaro
280 Barcellos for this patch.
282 2005-11-04, Version 3.3.0 (Revision 216)
283 * New modules have been added:
284 - `serial', for monitoring traffic on the serial interfaces
285 - `nfs', for graphing NFS procedure calls
286 - `tape', traffic from/to tape devices
287 * The the memory.rrd now accepts more than 4Gig of memory.
289 2005-10-26, Version 3.2.0 (Revision 200)
290 * Support for graphing the processes has been added (thanks to Lyonel
292 * If reading from hddtemp failes collectd will increase the time
293 between polls up to one day.
294 * The init.d files have been improved.
295 * Problems with the spec file have been fixed.
297 2005-10-16, Version 3.1.0 (Revision 194)
298 * Added the `setsid' syscall to the startup code.
299 * Support for hddtemp has been added (thanks to Vincent Stehlé)
301 2005-09-30, Version 3.0.0 (Revision 184)
302 * The ability to send/receive data to/from the network (think
303 multicast) has been added.
304 * Modules have been split up into shared libraries can be loaded at
305 runtime. The biggest advantage is that the core program doesn't need
306 to be linked against an external library.
307 * A patch by George Kargiotakis has been applied: It fixes the sensors
308 behaviour then more than one sensor is being queried.
310 2005-09-16, Version 2.1.0 (Revision 172)
311 * A module for swap statistics has been added.
313 2005-09-09, Version 2.0.0 (Revision 135)
314 * Filenames can no longer be configured at program startup. The only
315 options as of this version are the directory and ping hosts.
316 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
317 Soft-IRQ statistics are added to `System'.
318 * Diskstats now collect read and write bytes, not sectors.
319 * Ping statistics can now be collected for more than one host. There
320 is no default any more: If no host is given no host will be pinged.
321 * A self-written patch for libping has been applied so it builds
324 2005-09-01, Version 1.8.1 (Revision 123)
325 * Much improved configure-script: libraries and features may now be
327 * More detailed warnings/error messages when RRD update failes.
329 2005-08-29, Version 1.8.0:
330 * Support for collecting disk statistics under Solaris.
332 2005-08-25, Version 1.7.0:
333 * Support for libstatgrab[1] for load, memory usage and network
334 traffic. CPU- and disk-usage are not (yet) supported, since
335 libstatgrab returns insufficient information. I will contact the
337 * Improved the CPU-initialization code for Solaris. Apparently CPUs
338 aren't neccessarily counted linear which is now handled correctly.
339 [1]: http://www.i-scream.org/libstatgrab/
341 2005-08-21, Version 1.6.0:
342 * Basic support for Solaris: System load and cpu-usage can be
343 collected unter Solaris, too. Other stats will follow later.
344 * Many fixes in the autoconf-script
345 * Collection/Museum scripts have been added unter contrib/museum
346 * collectd may now be started in unprivileged mode, though ping
347 statistics will not work.
349 2005-07-17, Version 1.5.1:
350 * Diskstats-RRDs now use major/minor for naming. Some systems have
351 weird strings as disk-names..
353 2005-07-17, Version 1.5:
354 * A new module, diskstats, has been added. It collects information
355 about the disks and partitions.
357 2005-07-11, Version 1.4.2:
358 * The meminfo mofule has been changed to work with more platforms
359 and/or kernel versions.
361 2005-07-10, Version 1.4.1: Correct traffic stats
362 * The traffic rrd-file is now created with DS-type `COUNTER' which I
363 forgot to correct when I changed that module.
365 2005-07-09, Version 1.4: More traffic stats
366 * Traffic is now collected for all interfaces that can be found
367 * Temperature-statistics are read from lm-sensors if available
369 2005-07-08, Version 1.3: CPU stats
370 * Collecting CPU statistics now
372 2004-07-12, Version 1.2: Using syslog
373 * collectd is now using the syslog facility to report errors, warnings
375 * The default directory is now /var/db/collectd
377 2004-07-10, Version 1.1: Minor changes
378 * Nothing really usefull to say ;)
380 2004-07-09, Version 1.0: Initial Version
381 * The following modules are provided:
projects / collectd.git / blob
