1 2007-09-28, Version 3.11.7
2 * wireless plugin: Correct the handling of cards returning signal and
3 noise quality as percentage.
5 2007-08-31, Version 3.11.6
6 * processes plugin: Fix a potential segmentation fault.
8 2007-05-29, Version 3.11.5
9 * configure: Added `AC_SYS_LARGEFILE' for LFS.
10 * ntpd plugin: Fix a potential buffer overflow.
11 * processes plugin: Fix a bug when run under Linux 2.4. All processes
12 were accounted as `zombies'.
14 2007-04-10, Version 3.11.4
15 * dns plugin: Change the order of includes to make the plugin compile
18 2007-03-30, Version 3.11.3
19 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
20 of the unused `COLLECT_KSTAT'.
22 2007-02-11, Version 3.11.2
23 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
24 NULL-pointer may have been passed to `printf' which causes a
25 segfault with some libcs.
27 2007-02-10, Version 3.11.1
28 * df plugin: Some wrong defines have been fixed so the plugin works
30 * dns plugin: The usage of a struct has been fixed to work with
32 * processes plugin: Some missing defines have been added so the plugin
33 compiles cleanly under FreeBSD and presumably other UNIXes.
35 2006-12-22, Version 3.11.0
36 * collectd: The new command line option `-P' makes it easier for
37 distributors to change the location of PID-files.
38 * collectd: The daemon shuts down faster now which makes it easier to
39 write init.d-scripts for it.
40 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
41 caused problems every now and then.
42 * df plugin: New config options allow to ignore certain mountpoints,
43 filesystem types or devices.
44 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
45 and interprets it. It collects traffic as well as qtype, opcode and
47 * email plugin: Sebastian Harl has contributed this plugin which
48 counts received mails in categories (e. g. ham, spam, virus), spam
49 score (as given by SpamAssassin) and check types.
50 * mbmon plugin: Flavio Stanchina has contributed this plugin which
51 uses `mbmon' to gather information from sensors on the motherboard.
52 * processes plugin: Collect detailed statistics for configured
53 processes, that's process and thread count, CPU usage, resident
54 segment size and pagefaults.
55 * multimeter plugin: Peter Holik contributed a new plugin which
57 * sensors plugin: Lubos Stanek has put much effort into improving this
58 plugin, including `extended naming', collection of voltage values
59 and the possibility to ignore certain values.
61 2006-12-21, Version 3.10.4
62 * Max Kellermann has identified a bug in the server routine: When
63 opening a socket fails the daemon will (re)try opening the socket in
64 an endless loop, ultimately leading to a `EMFILE' error.
66 2006-11-04, Version 3.10.3
67 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
68 ntpd's reply was sent in more than one packet, the buffer size was
69 calculated incorrectly, resulting in the reading of uninitialized or
72 2006-11-01, Version 3.10.2
73 * The sample config file has been improved.
74 * Errors in the manpages have been corrected.
75 * The ping-plugin now adds hosts during initialization, not during
76 startup. This speeds up starup when no network connectivity is
77 available. Also, the hosts are being added later when the network is
79 * Improved BSD-support for the df-plugin.
80 * Fixed syntax errors in the swap-plugin for Mac OS X.
81 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
83 * Don't disable the mysql-plugin if connecting to the database fails
84 during initialization. Instead, try again in increasing intervals.
86 2006-07-19, Version 3.10.1
87 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
88 the apcups cannot be reached, unconnected sockets will pile up and
89 eventually lead to `Too many open files' errors.
91 2006-07-09, Version 3.10.0
92 * The `disk' plugin has been ported to Darwin.
93 * The `battery' plugin should work on many Apple computers now.
94 * The `traffic' plugin can now ignore certain interfaces. Also,
95 statistics for sent/received packets and errors have been added.
96 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
97 to Anthony Gialluca for contributing this plugin and providing me
98 with a test environment :)
99 * A plugin for moniroting an NTP instance and the local clock drift
102 2006-06-25, Version 3.9.4
103 * The Solaris code in the `swap' plugin has been changed to reflect
104 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
106 * The debugging system has been fixed to work with the Sun libc.
107 * When built without librrd the variable `operating_mode' could be
108 uninitialized. Thanks to David Elliot for reporting the bug.
110 2006-06-01, Version 3.9.3
111 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
112 operating systems also profit from the changes, but I wasn't able to
114 * Changed the build system to find the netinet-includes under FreeBSD
115 and therefore successfully build the `liboping' library there.
117 2006-05-09, Version 3.9.2
118 * Applied a patch to the `liboping' library. Due to a bug in the
119 sequence checking the `ping' plugin stopped working after
120 approximately 7.6 days.
122 2006-05-09, Version 3.8.5
123 * Applied a patch to the `liboping' library. Due to a bug in the
124 sequence checking the `ping' plugin stopped working after
125 approximately 7.6 days.
127 2006-04-21, Version 3.9.1
128 * Build issues with Solaris and possible other architectures have been
130 * Problems when building the `apache'-plugin without `libcurl' have
132 * A bug in the `ping' plugin has been fixed. Sorry folks.
134 2006-04-02, Version 3.9.0
135 * A plugin to monitor the Apache webserver has been added.
136 <http://httpd.apache.org/>
137 * A plugin to collect statistics about virtual servers using VServer.
138 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

141 strength, link quality and noise ratio..
142 * A plugin for Apple hardware sensors has been added.
143 * An option to compile collectd with different `step' and `hearbeat'
144 settings has been added. The size of RRAs is no longer static but
145 calculated based on the settings for `step' and `width'.
146 * The `ping' plugin can now be configured to use a certain TTL.
147 * A plugin to monitor the hardware sensors of Apple computers has been
149 * The plugins `cpu', `memory', `processes' and `traffic' have been
150 ported to Mach/Darwin (Mac OS X).
151 * The `log mode' has been contributed by Christophe Kalt. It writes
152 the data into text files rather than RRD files.
154 2006-04-09, Version 3.8.4
155 * Applied patch by Vincent Stehlé which improves the disk-name
156 resolution in the `hddtemp' plugin for Linux systems.
158 2006-04-02, Version 3.8.3
159 * Applied a patch by James Byers: The MySQL plugin was not working
160 with MySQL 5.0.2 or later.
162 2006-03-14, Version 3.8.2
163 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
164 the GNU libc, because it points to `/etc/fstab' rather than
167 2006-03-13, Version 3.8.1
168 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
169 * Fixes in the debian `postinst' and `init.d' scripts.
171 2006-03-09, Version 3.8.0
172 * The `ping' plugin no longer uses `libping' but a self written
173 library named `liboping'. With this library it's possible to ping
174 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
176 2006-02-18, Version 3.7.2
177 * A simple bug in the `battery' plugin has been fixed. It should now
178 work with ACPI based batteries as well. Thankt to Sebastian for
180 * Fixing a bug that prevented collectd to be built without librrd.
181 Thanks to Werner Heuser for reporting it.
183 2006-02-04, Version 3.7.1
184 * The new network code has been improved to build with older versions
186 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
187 to Tommie Gannert for this patch.
189 2006-01-30, Version 3.7.0
190 * The `battery' plugin has been added. It collects information about
192 * The MySQL plugin has been improved: It now writes two more RRD
193 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
194 * The `cpufreq' plugin now reads another file since the file it did
195 read so far causes much overhead in the kernel. Also, you need root
196 to read the old file, but not to read the new one.
197 * The `hddtemp' plugin can now be configured to connect to another
198 address and/or port than localhost.
199 * The `df' plugin now prefers `statvfs' over `statfs'.
200 * The network code has been rewritten. collectd now supports unicast
201 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
202 be set in the configfile.
204 2006-01-24, Version 3.6.2
205 * Due to a bug in the configfile handling collectd wouldn't start in
206 client mode. This released fixes this.
208 2006-01-20, Version 3.6.1
209 * Due to a bug in `configure.in' all modules and the binary were
210 linked against `libmysqlclient'. This issue is solved by this
213 2006-01-17, Version 3.6.0
214 * A config file has been added. This allows for loading only specific
216 * A `df' plugin has been added.
217 * A `mysql' plugin has been added.
218 * The `ping' plugin doesn't entirely give up hope when a socket error
219 occured, but will back of and increase the intervals between tries.
221 2006-01-21, Version 3.5.2
222 * Fixed yet another bug in the signal handling.. Stupid typo..
223 * Improved the ping plugin to not give up on socket errors (backport
226 2005-12-18, Version 3.5.1
227 * The PID-file is now deleted correctly when shutting down the daemon.
228 * SIGINT and SIGTERM are now handled correctly.
230 2005-12-16, Version 3.5.0 (Revision 326)
231 * A bug in the `load' module under Solaris has been fixed.
232 * The `users' module has been contributed by Sebastian Harl. It counts
233 currently logged in users.
234 * The CPU module now works under FreeBSD without the use of
235 `libstatgrab', however SMP support is missing.
236 * The default directories for the RRD files and the PID file now
237 depend on the compile time setting of `localstatedir'.
239 2005-11-15, Version 3.4.0 (Revision 236)
240 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
241 from gentoo's bugzilla for writing the patch.
242 * The build dependency for librrd has been removed. Binaries built
243 without librrd are client-only and will multicast their value as
244 with the `-c' argument.
245 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
246 * The newly introduced `-f' switch prevents daemon initialization
247 (forking, closing standard filehandles, etc.) Thanks to Alvaro
248 Barcellos for this patch.
250 2005-11-04, Version 3.3.0 (Revision 216)
251 * New modules have been added:
252 - `serial', for monitoring traffic on the serial interfaces
253 - `nfs', for graphing NFS procedure calls
254 - `tape', traffic from/to tape devices
255 * The the memory.rrd now accepts more than 4Gig of memory.
257 2005-10-26, Version 3.2.0 (Revision 200)
258 * Support for graphing the processes has been added (thanks to Lyonel
260 * If reading from hddtemp failes collectd will increase the time
261 between polls up to one day.
262 * The init.d files have been improved.
263 * Problems with the spec file have been fixed.
265 2005-10-16, Version 3.1.0 (Revision 194)
266 * Added the `setsid' syscall to the startup code.
267 * Support for hddtemp has been added (thanks to Vincent Stehlé)
269 2005-09-30, Version 3.0.0 (Revision 184)
270 * The ability to send/receive data to/from the network (think
271 multicast) has been added.
272 * Modules have been split up into shared libraries can be loaded at
273 runtime. The biggest advantage is that the core program doesn't need
274 to be linked against an external library.
275 * A patch by George Kargiotakis has been applied: It fixes the sensors
276 behaviour then more than one sensor is being queried.
278 2005-09-16, Version 2.1.0 (Revision 172)
279 * A module for swap statistics has been added.
281 2005-09-09, Version 2.0.0 (Revision 135)
282 * Filenames can no longer be configured at program startup. The only
283 options as of this version are the directory and ping hosts.
284 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
285 Soft-IRQ statistics are added to `System'.
286 * Diskstats now collect read and write bytes, not sectors.
287 * Ping statistics can now be collected for more than one host. There
288 is no default any more: If no host is given no host will be pinged.
289 * A self-written patch for libping has been applied so it builds
292 2005-09-01, Version 1.8.1 (Revision 123)
293 * Much improved configure-script: libraries and features may now be
295 * More detailed warnings/error messages when RRD update failes.
297 2005-08-29, Version 1.8.0:
298 * Support for collecting disk statistics under Solaris.
300 2005-08-25, Version 1.7.0:
301 * Support for libstatgrab[1] for load, memory usage and network
302 traffic. CPU- and disk-usage are not (yet) supported, since
303 libstatgrab returns insufficient information. I will contact the
305 * Improved the CPU-initialization code for Solaris. Apparently CPUs
306 aren't neccessarily counted linear which is now handled correctly.
307 [1]: http://www.i-scream.org/libstatgrab/
309 2005-08-21, Version 1.6.0:
310 * Basic support for Solaris: System load and cpu-usage can be
311 collected unter Solaris, too. Other stats will follow later.
312 * Many fixes in the autoconf-script
313 * Collection/Museum scripts have been added unter contrib/museum
314 * collectd may now be started in unprivileged mode, though ping
315 statistics will not work.
317 2005-07-17, Version 1.5.1:
318 * Diskstats-RRDs now use major/minor for naming. Some systems have
319 weird strings as disk-names..
321 2005-07-17, Version 1.5:
322 * A new module, diskstats, has been added. It collects information
323 about the disks and partitions.
325 2005-07-11, Version 1.4.2:
326 * The meminfo mofule has been changed to work with more platforms
327 and/or kernel versions.
329 2005-07-10, Version 1.4.1: Correct traffic stats
330 * The traffic rrd-file is now created with DS-type `COUNTER' which I
331 forgot to correct when I changed that module.
333 2005-07-09, Version 1.4: More traffic stats
334 * Traffic is now collected for all interfaces that can be found
335 * Temperature-statistics are read from lm-sensors if available
337 2005-07-08, Version 1.3: CPU stats
338 * Collecting CPU statistics now
340 2004-07-12, Version 1.2: Using syslog
341 * collectd is now using the syslog facility to report errors, warnings
343 * The default directory is now /var/db/collectd
345 2004-07-10, Version 1.1: Minor changes
346 * Nothing really usefull to say ;)
348 2004-07-09, Version 1.0: Initial Version
349 * The following modules are provided:
