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 * csv plugin: The new `csv' plugin handles output to `comma seperated
9 * rrdtool plugin: The new `rrdtool' plugin handles output to
10 RRD-files. Data can be cached to combine multiple updates into one
11 write to increase IO-performance.
12 * network plugin: The new `network' plugin handles IO via the network.
13 It implements a different, much more extensible protocol which can
14 combine many values in one packet, decreasing the number of UDP-
15 packets being sent. It can read from and send to the network and
16 with the appropriate configuration even forward packets to other
18 * unixsock plugin: The new `unixsock' plugin provides an interface to
19 communicate with the daemon while it is running. Right now the
20 commands `GETVAL' and `PUTVAL' are implemented, but more are to
22 * logfile plugin: The new `logfile' plugin writes logmessages to files
24 * syslog plugin: The new `syslog' plugin sends logmessages to the
25 system's syslog daemon.
26 * entropy plugin: The new `entropy' plugin collects the amount of
27 entropy currently being available to the system.
28 * exec plugin: The new `exec' plugin forks child processes and reads
29 back values provided by the forked processes.
30 * iptables plugin: The new `iptables' plugin reads counters from
31 iptables rules. Thanks to Sjoerd van der Berg for contributing this
33 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
34 to Peter Holik for contributing this plugin.
35 * nut plugin: The new `nut' plugin connects the the upsd of the
36 `network ups tools' and reads information about the connected UPS.
37 * apache plugin: Support for lighttpd's `BusyServers' (aka.
38 connections) field was added by Florent Monbillard.
39 * collectd-nagios: The new `collectd-nagios' binary queries values
40 from collectd, parses them and exits according to Nagios-standards.
42 2007-03-30, Version 3.11.3
43 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
44 of the unused `COLLECT_KSTAT'.
46 2007-02-11, Version 3.11.2
47 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
48 NULL-pointer may have been passed to `printf' which causes a
49 segfault with some libcs.
51 2007-02-10, Version 3.11.1
52 * df plugin: Some wrong defines have been fixed so the plugin works
54 * dns plugin: The usage of a struct has been fixed to work with
56 * processes plugin: Some missing defines have been added so the plugin
57 compiles cleanly under FreeBSD and presumably other UNIXes.
59 2006-12-22, Version 3.11.0
60 * collectd: The new command line option `-P' makes it easier for
61 distributors to change the location of PID-files.
62 * collectd: The daemon shuts down faster now which makes it easier to
63 write init.d-scripts for it.
64 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
65 caused problems every now and then.
66 * df plugin: New config options allow to ignore certain mountpoints,
67 filesystem types or devices.
68 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
69 and interprets it. It collects traffic as well as qtype, opcode and
71 * email plugin: Sebastian Harl has contributed this plugin which
72 counts received mails in categories (e. g. ham, spam, virus), spam
73 score (as given by SpamAssassin) and check types.
74 * mbmon plugin: Flavio Stanchina has contributed this plugin which
75 uses `mbmon' to gather information from sensors on the motherboard.
76 * processes plugin: Collect detailed statistics for configured
77 processes, that's process and thread count, CPU usage, resident
78 segment size and pagefaults.
79 * multimeter plugin: Peter Holik contributed a new plugin which
81 * sensors plugin: Lubos Stanek has put much effort into improving this
82 plugin, including `extended naming', collection of voltage values
83 and the possibility to ignore certain values.
85 2006-12-21, Version 3.10.4
86 * Max Kellermann has identified a bug in the server routine: When
87 opening a socket fails the daemon will (re)try opening the socket in
88 an endless loop, ultimately leading to a `EMFILE' error.
90 2006-11-04, Version 3.10.3
91 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
92 ntpd's reply was sent in more than one packet, the buffer size was
93 calculated incorrectly, resulting in the reading of uninitialized or
96 2006-11-01, Version 3.10.2
97 * The sample config file has been improved.
98 * Errors in the manpages have been corrected.
99 * The ping-plugin now adds hosts during initialization, not during
100 startup. This speeds up starup when no network connectivity is
101 available. Also, the hosts are being added later when the network is
103 * Improved BSD-support for the df-plugin.
104 * Fixed syntax errors in the swap-plugin for Mac OS X.
105 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
107 * Don't disable the mysql-plugin if connecting to the database fails
108 during initialization. Instead, try again in increasing intervals.
110 2006-07-19, Version 3.10.1
111 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
112 the apcups cannot be reached, unconnected sockets will pile up and
113 eventually lead to `Too many open files' errors.
115 2006-07-09, Version 3.10.0
116 * The `disk' plugin has been ported to Darwin.
117 * The `battery' plugin should work on many Apple computers now.
118 * The `traffic' plugin can now ignore certain interfaces. Also,
119 statistics for sent/received packets and errors have been added.
120 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
121 to Anthony Gialluca for contributing this plugin and providing me
122 with a test environment :)
123 * A plugin for moniroting an NTP instance and the local clock drift
126 2006-06-25, Version 3.9.4
127 * The Solaris code in the `swap' plugin has been changed to reflect
128 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
130 * The debugging system has been fixed to work with the Sun libc.
131 * When built without librrd the variable `operating_mode' could be
132 uninitialized. Thanks to David Elliot for reporting the bug.
134 2006-06-01, Version 3.9.3
135 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
136 operating systems also profit from the changes, but I wasn't able to
138 * Changed the build system to find the netinet-includes under FreeBSD
139 and therefore successfully build the `liboping' library there.
141 2006-05-09, Version 3.9.2
142 * Applied a patch to the `liboping' library. Due to a bug in the
143 sequence checking the `ping' plugin stopped working after
144 approximately 7.6 days.
146 2006-05-09, Version 3.8.5
147 * Applied a patch to the `liboping' library. Due to a bug in the
148 sequence checking the `ping' plugin stopped working after
149 approximately 7.6 days.
151 2006-04-21, Version 3.9.1
152 * Build issues with Solaris and possible other architectures have been
154 * Problems when building the `apache'-plugin without `libcurl' have
156 * A bug in the `ping' plugin has been fixed. Sorry folks.
158 2006-04-02, Version 3.9.0
159 * A plugin to monitor the Apache webserver has been added.
160 <http://httpd.apache.org/>
161 * A plugin to collect statistics about virtual servers using VServer.
162 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
164 * A plugin for wireless LAN cards has been added. It monitors signal
165 strength, link quality and noise ratio..
166 * A plugin for Apple hardware sensors has been added.
167 * An option to compile collectd with different `step' and `hearbeat'
168 settings has been added. The size of RRAs is no longer static but
169 calculated based on the settings for `step' and `width'.
170 * The `ping' plugin can now be configured to use a certain TTL.
171 * A plugin to monitor the hardware sensors of Apple computers has been
173 * The plugins `cpu', `memory', `processes' and `traffic' have been
174 ported to Mach/Darwin (Mac OS X).
175 * The `log mode' has been contributed by Christophe Kalt. It writes
176 the data into text files rather than RRD files.
178 2006-04-09, Version 3.8.4
179 * Applied patch by Vincent Stehlé which improves the disk-name
180 resolution in the `hddtemp' plugin for Linux systems.
182 2006-04-02, Version 3.8.3
183 * Applied a patch by James Byers: The MySQL plugin was not working
184 with MySQL 5.0.2 or later.
186 2006-03-14, Version 3.8.2
187 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
188 the GNU libc, because it points to `/etc/fstab' rather than
191 2006-03-13, Version 3.8.1
192 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
193 * Fixes in the debian `postinst' and `init.d' scripts.
195 2006-03-09, Version 3.8.0
196 * The `ping' plugin no longer uses `libping' but a self written
197 library named `liboping'. With this library it's possible to ping
198 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
200 2006-02-18, Version 3.7.2
201 * A simple bug in the `battery' plugin has been fixed. It should now
202 work with ACPI based batteries as well. Thankt to Sebastian for
204 * Fixing a bug that prevented collectd to be built without librrd.
205 Thanks to Werner Heuser for reporting it.
207 2006-02-04, Version 3.7.1
208 * The new network code has been improved to build with older versions
210 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
211 to Tommie Gannert for this patch.
213 2006-01-30, Version 3.7.0
214 * The `battery' plugin has been added. It collects information about
216 * The MySQL plugin has been improved: It now writes two more RRD
217 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
218 * The `cpufreq' plugin now reads another file since the file it did
219 read so far causes much overhead in the kernel. Also, you need root
220 to read the old file, but not to read the new one.
221 * The `hddtemp' plugin can now be configured to connect to another
222 address and/or port than localhost.
223 * The `df' plugin now prefers `statvfs' over `statfs'.
224 * The network code has been rewritten. collectd now supports unicast
225 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
226 be set in the configfile.
228 2006-01-24, Version 3.6.2
229 * Due to a bug in the configfile handling collectd wouldn't start in
230 client mode. This released fixes this.
232 2006-01-20, Version 3.6.1
233 * Due to a bug in `configure.in' all modules and the binary were
234 linked against `libmysqlclient'. This issue is solved by this
237 2006-01-17, Version 3.6.0
238 * A config file has been added. This allows for loading only specific
240 * A `df' plugin has been added.
241 * A `mysql' plugin has been added.
242 * The `ping' plugin doesn't entirely give up hope when a socket error
243 occured, but will back of and increase the intervals between tries.
245 2006-01-21, Version 3.5.2
246 * Fixed yet another bug in the signal handling.. Stupid typo..
247 * Improved the ping plugin to not give up on socket errors (backport
250 2005-12-18, Version 3.5.1
251 * The PID-file is now deleted correctly when shutting down the daemon.
252 * SIGINT and SIGTERM are now handled correctly.
254 2005-12-16, Version 3.5.0 (Revision 326)
255 * A bug in the `load' module under Solaris has been fixed.
256 * The `users' module has been contributed by Sebastian Harl. It counts
257 currently logged in users.
258 * The CPU module now works under FreeBSD without the use of
259 `libstatgrab', however SMP support is missing.
260 * The default directories for the RRD files and the PID file now
261 depend on the compile time setting of `localstatedir'.
263 2005-11-15, Version 3.4.0 (Revision 236)
264 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
265 from gentoo's bugzilla for writing the patch.
266 * The build dependency for librrd has been removed. Binaries built
267 without librrd are client-only and will multicast their value as
268 with the `-c' argument.
269 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
270 * The newly introduced `-f' switch prevents daemon initialization
271 (forking, closing standard filehandles, etc.) Thanks to Alvaro
272 Barcellos for this patch.
274 2005-11-04, Version 3.3.0 (Revision 216)
275 * New modules have been added:
276 - `serial', for monitoring traffic on the serial interfaces
277 - `nfs', for graphing NFS procedure calls
278 - `tape', traffic from/to tape devices
279 * The the memory.rrd now accepts more than 4Gig of memory.
281 2005-10-26, Version 3.2.0 (Revision 200)
282 * Support for graphing the processes has been added (thanks to Lyonel
284 * If reading from hddtemp failes collectd will increase the time
285 between polls up to one day.
286 * The init.d files have been improved.
287 * Problems with the spec file have been fixed.
289 2005-10-16, Version 3.1.0 (Revision 194)
290 * Added the `setsid' syscall to the startup code.
291 * Support for hddtemp has been added (thanks to Vincent Stehlé)
293 2005-09-30, Version 3.0.0 (Revision 184)
294 * The ability to send/receive data to/from the network (think
295 multicast) has been added.
296 * Modules have been split up into shared libraries can be loaded at
297 runtime. The biggest advantage is that the core program doesn't need
298 to be linked against an external library.
299 * A patch by George Kargiotakis has been applied: It fixes the sensors
300 behaviour then more than one sensor is being queried.
302 2005-09-16, Version 2.1.0 (Revision 172)
303 * A module for swap statistics has been added.
305 2005-09-09, Version 2.0.0 (Revision 135)
306 * Filenames can no longer be configured at program startup. The only
307 options as of this version are the directory and ping hosts.
308 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
309 Soft-IRQ statistics are added to `System'.
310 * Diskstats now collect read and write bytes, not sectors.
311 * Ping statistics can now be collected for more than one host. There
312 is no default any more: If no host is given no host will be pinged.
313 * A self-written patch for libping has been applied so it builds
316 2005-09-01, Version 1.8.1 (Revision 123)
317 * Much improved configure-script: libraries and features may now be
319 * More detailed warnings/error messages when RRD update failes.
321 2005-08-29, Version 1.8.0:
322 * Support for collecting disk statistics under Solaris.
324 2005-08-25, Version 1.7.0:
325 * Support for libstatgrab[1] for load, memory usage and network
326 traffic. CPU- and disk-usage are not (yet) supported, since
327 libstatgrab returns insufficient information. I will contact the
329 * Improved the CPU-initialization code for Solaris. Apparently CPUs
330 aren't neccessarily counted linear which is now handled correctly.
331 [1]: http://www.i-scream.org/libstatgrab/
333 2005-08-21, Version 1.6.0:
334 * Basic support for Solaris: System load and cpu-usage can be
335 collected unter Solaris, too. Other stats will follow later.
336 * Many fixes in the autoconf-script
337 * Collection/Museum scripts have been added unter contrib/museum
338 * collectd may now be started in unprivileged mode, though ping
339 statistics will not work.
341 2005-07-17, Version 1.5.1:
342 * Diskstats-RRDs now use major/minor for naming. Some systems have
343 weird strings as disk-names..
345 2005-07-17, Version 1.5:
346 * A new module, diskstats, has been added. It collects information
347 about the disks and partitions.
349 2005-07-11, Version 1.4.2:
350 * The meminfo mofule has been changed to work with more platforms
351 and/or kernel versions.
353 2005-07-10, Version 1.4.1: Correct traffic stats
354 * The traffic rrd-file is now created with DS-type `COUNTER' which I
355 forgot to correct when I changed that module.
357 2005-07-09, Version 1.4: More traffic stats
358 * Traffic is now collected for all interfaces that can be found
359 * Temperature-statistics are read from lm-sensors if available
361 2005-07-08, Version 1.3: CPU stats
362 * Collecting CPU statistics now
364 2004-07-12, Version 1.2: Using syslog
365 * collectd is now using the syslog facility to report errors, warnings
367 * The default directory is now /var/db/collectd
369 2004-07-10, Version 1.1: Minor changes
370 * Nothing really usefull to say ;)
372 2004-07-09, Version 1.0: Initial Version
373 * The following modules are provided:
