1 2007-02-11, Version 3.11.2
2 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3 NULL-pointer may have been passed to `printf' which causes a
4 segfault with some libcs.
6 2007-02-10, Version 3.11.1
7 * df plugin: Some wrong defines have been fixed so the plugin works
9 * dns plugin: The usage of a struct has been fixed to work with
11 * processes plugin: Some missing defines have been added so the plugin
12 compiles cleanly under FreeBSD and presumably other UNIXes.
14 2006-12-22, Version 3.11.0
15 * collectd: The new command line option `-P' makes it easier for
16 distributors to change the location of PID-files.
17 * collectd: The daemon shuts down faster now which makes it easier to
18 write init.d-scripts for it.
19 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
20 caused problems every now and then.
21 * df plugin: New config options allow to ignore certain mountpoints,
22 filesystem types or devices.
23 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
24 and interprets it. It collects traffic as well as qtype, opcode and
26 * email plugin: Sebastian Harl has contributed this plugin which
27 counts received mails in categories (e. g. ham, spam, virus), spam
28 score (as given by SpamAssassin) and check types.
29 * mbmon plugin: Flavio Stanchina has contributed this plugin which
30 uses `mbmon' to gather information from sensors on the motherboard.
31 * processes plugin: Collect detailed statistics for configured
32 processes, that's process and thread count, CPU usage, resident
33 segment size and pagefaults.
34 * multimeter plugin: Peter Holik contributed a new plugin which
36 * sensors plugin: Lubos Stanek has put much effort into improving this
37 plugin, including `extended naming', collection of voltage values
38 and the possibility to ignore certain values.
40 2006-12-21, Version 3.10.4
41 * Max Kellermann has identified a bug in the server routine: When
42 opening a socket fails the daemon will (re)try opening the socket in
43 an endless loop, ultimately leading to a `EMFILE' error.
45 2006-11-04, Version 3.10.3
46 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
47 ntpd's reply was sent in more than one packet, the buffer size was
48 calculated incorrectly, resulting in the reading of uninitialized or
51 2006-11-01, Version 3.10.2
52 * The sample config file has been improved.
53 * Errors in the manpages have been corrected.
54 * The ping-plugin now adds hosts during initialization, not during
55 startup. This speeds up starup when no network connectivity is
56 available. Also, the hosts are being added later when the network is
58 * Improved BSD-support for the df-plugin.
59 * Fixed syntax errors in the swap-plugin for Mac OS X.
60 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
62 * Don't disable the mysql-plugin if connecting to the database fails
63 during initialization. Instead, try again in increasing intervals.
65 2006-07-19, Version 3.10.1
66 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
67 the apcups cannot be reached, unconnected sockets will pile up and
68 eventually lead to `Too many open files' errors.
70 2006-07-09, Version 3.10.0
71 * The `disk' plugin has been ported to Darwin.
72 * The `battery' plugin should work on many Apple computers now.
73 * The `traffic' plugin can now ignore certain interfaces. Also,
74 statistics for sent/received packets and errors have been added.
75 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
76 to Anthony Gialluca for contributing this plugin and providing me
77 with a test environment :)
78 * A plugin for moniroting an NTP instance and the local clock drift
81 2006-06-25, Version 3.9.4
82 * The Solaris code in the `swap' plugin has been changed to reflect
83 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
85 * The debugging system has been fixed to work with the Sun libc.
86 * When built without librrd the variable `operating_mode' could be
87 uninitialized. Thanks to David Elliot for reporting the bug.
89 2006-06-01, Version 3.9.3
90 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
91 operating systems also profit from the changes, but I wasn't able to
93 * Changed the build system to find the netinet-includes under FreeBSD
94 and therefore successfully build the `liboping' library there.
96 2006-05-09, Version 3.9.2
97 * Applied a patch to the `liboping' library. Due to a bug in the
98 sequence checking the `ping' plugin stopped working after
99 approximately 7.6 days.
101 2006-05-09, Version 3.8.5
102 * Applied a patch to the `liboping' library. Due to a bug in the
103 sequence checking the `ping' plugin stopped working after
104 approximately 7.6 days.
106 2006-04-21, Version 3.9.1
107 * Build issues with Solaris and possible other architectures have been
109 * Problems when building the `apache'-plugin without `libcurl' have
111 * A bug in the `ping' plugin has been fixed. Sorry folks.
113 2006-04-02, Version 3.9.0
114 * A plugin to monitor the Apache webserver has been added.
115 <http://httpd.apache.org/>
116 * A plugin to collect statistics about virtual servers using VServer.
117 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
119 * A plugin for wireless LAN cards has been added. It monitors signal
120 strength, link quality and noise ratio..
121 * A plugin for Apple hardware sensors has been added.
122 * An option to compile collectd with different `step' and `hearbeat'
123 settings has been added. The size of RRAs is no longer static but
124 calculated based on the settings for `step' and `width'.
125 * The `ping' plugin can now be configured to use a certain TTL.
126 * A plugin to monitor the hardware sensors of Apple computers has been
128 * The plugins `cpu', `memory', `processes' and `traffic' have been
129 ported to Mach/Darwin (Mac OS X).
130 * The `log mode' has been contributed by Christophe Kalt. It writes
131 the data into text files rather than RRD files.
133 2006-04-09, Version 3.8.4
134 * Applied patch by Vincent Stehlé which improves the disk-name
135 resolution in the `hddtemp' plugin for Linux systems.
137 2006-04-02, Version 3.8.3
138 * Applied a patch by James Byers: The MySQL plugin was not working
139 with MySQL 5.0.2 or later.
141 2006-03-14, Version 3.8.2
142 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
143 the GNU libc, because it points to `/etc/fstab' rather than
146 2006-03-13, Version 3.8.1
147 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
148 * Fixes in the debian `postinst' and `init.d' scripts.
150 2006-03-09, Version 3.8.0
151 * The `ping' plugin no longer uses `libping' but a self written
152 library named `liboping'. With this library it's possible to ping
153 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
155 2006-02-18, Version 3.7.2
156 * A simple bug in the `battery' plugin has been fixed. It should now
157 work with ACPI based batteries as well. Thankt to Sebastian for
159 * Fixing a bug that prevented collectd to be built without librrd.
160 Thanks to Werner Heuser for reporting it.
162 2006-02-04, Version 3.7.1
163 * The new network code has been improved to build with older versions
165 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
166 to Tommie Gannert for this patch.
168 2006-01-30, Version 3.7.0
169 * The `battery' plugin has been added. It collects information about
171 * The MySQL plugin has been improved: It now writes two more RRD
172 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
173 * The `cpufreq' plugin now reads another file since the file it did
174 read so far causes much overhead in the kernel. Also, you need root
175 to read the old file, but not to read the new one.
176 * The `hddtemp' plugin can now be configured to connect to another
177 address and/or port than localhost.
178 * The `df' plugin now prefers `statvfs' over `statfs'.
179 * The network code has been rewritten. collectd now supports unicast
180 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
181 be set in the configfile.
183 2006-01-24, Version 3.6.2
184 * Due to a bug in the configfile handling collectd wouldn't start in
185 client mode. This released fixes this.
187 2006-01-20, Version 3.6.1
188 * Due to a bug in `configure.in' all modules and the binary were
189 linked against `libmysqlclient'. This issue is solved by this
192 2006-01-17, Version 3.6.0
193 * A config file has been added. This allows for loading only specific
195 * A `df' plugin has been added.
196 * A `mysql' plugin has been added.
197 * The `ping' plugin doesn't entirely give up hope when a socket error
198 occured, but will back of and increase the intervals between tries.
200 2006-01-21, Version 3.5.2
201 * Fixed yet another bug in the signal handling.. Stupid typo..
202 * Improved the ping plugin to not give up on socket errors (backport
205 2005-12-18, Version 3.5.1
206 * The PID-file is now deleted correctly when shutting down the daemon.
207 * SIGINT and SIGTERM are now handled correctly.
209 2005-12-16, Version 3.5.0 (Revision 326)
210 * A bug in the `load' module under Solaris has been fixed.
211 * The `users' module has been contributed by Sebastian Harl. It counts
212 currently logged in users.
213 * The CPU module now works under FreeBSD without the use of
214 `libstatgrab', however SMP support is missing.
215 * The default directories for the RRD files and the PID file now
216 depend on the compile time setting of `localstatedir'.
218 2005-11-15, Version 3.4.0 (Revision 236)
219 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
220 from gentoo's bugzilla for writing the patch.
221 * The build dependency for librrd has been removed. Binaries built
222 without librrd are client-only and will multicast their value as
223 with the `-c' argument.
224 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
225 * The newly introduced `-f' switch prevents daemon initialization
226 (forking, closing standard filehandles, etc.) Thanks to Alvaro
227 Barcellos for this patch.
229 2005-11-04, Version 3.3.0 (Revision 216)
230 * New modules have been added:
231 - `serial', for monitoring traffic on the serial interfaces
232 - `nfs', for graphing NFS procedure calls
233 - `tape', traffic from/to tape devices
234 * The the memory.rrd now accepts more than 4Gig of memory.
236 2005-10-26, Version 3.2.0 (Revision 200)
237 * Support for graphing the processes has been added (thanks to Lyonel
239 * If reading from hddtemp failes collectd will increase the time
240 between polls up to one day.
241 * The init.d files have been improved.
242 * Problems with the spec file have been fixed.
244 2005-10-16, Version 3.1.0 (Revision 194)
245 * Added the `setsid' syscall to the startup code.
246 * Support for hddtemp has been added (thanks to Vincent Stehlé)
248 2005-09-30, Version 3.0.0 (Revision 184)
249 * The ability to send/receive data to/from the network (think
250 multicast) has been added.
251 * Modules have been split up into shared libraries can be loaded at
252 runtime. The biggest advantage is that the core program doesn't need
253 to be linked against an external library.
254 * A patch by George Kargiotakis has been applied: It fixes the sensors
255 behaviour then more than one sensor is being queried.
257 2005-09-16, Version 2.1.0 (Revision 172)
258 * A module for swap statistics has been added.
260 2005-09-09, Version 2.0.0 (Revision 135)
261 * Filenames can no longer be configured at program startup. The only
262 options as of this version are the directory and ping hosts.
263 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
264 Soft-IRQ statistics are added to `System'.
265 * Diskstats now collect read and write bytes, not sectors.
266 * Ping statistics can now be collected for more than one host. There
267 is no default any more: If no host is given no host will be pinged.
268 * A self-written patch for libping has been applied so it builds
271 2005-09-01, Version 1.8.1 (Revision 123)
272 * Much improved configure-script: libraries and features may now be
274 * More detailed warnings/error messages when RRD update failes.
276 2005-08-29, Version 1.8.0:
277 * Support for collecting disk statistics under Solaris.
279 2005-08-25, Version 1.7.0:
280 * Support for libstatgrab[1] for load, memory usage and network
281 traffic. CPU- and disk-usage are not (yet) supported, since
282 libstatgrab returns insufficient information. I will contact the
284 * Improved the CPU-initialization code for Solaris. Apparently CPUs
285 aren't neccessarily counted linear which is now handled correctly.
286 [1]: http://www.i-scream.org/libstatgrab/
288 2005-08-21, Version 1.6.0:
289 * Basic support for Solaris: System load and cpu-usage can be
290 collected unter Solaris, too. Other stats will follow later.
291 * Many fixes in the autoconf-script
292 * Collection/Museum scripts have been added unter contrib/museum
293 * collectd may now be started in unprivileged mode, though ping
294 statistics will not work.
296 2005-07-17, Version 1.5.1:
297 * Diskstats-RRDs now use major/minor for naming. Some systems have
298 weird strings as disk-names..
300 2005-07-17, Version 1.5:
301 * A new module, diskstats, has been added. It collects information
302 about the disks and partitions.
304 2005-07-11, Version 1.4.2:
305 * The meminfo mofule has been changed to work with more platforms
306 and/or kernel versions.
308 2005-07-10, Version 1.4.1: Correct traffic stats
309 * The traffic rrd-file is now created with DS-type `COUNTER' which I
310 forgot to correct when I changed that module.
312 2005-07-09, Version 1.4: More traffic stats
313 * Traffic is now collected for all interfaces that can be found
314 * Temperature-statistics are read from lm-sensors if available
316 2005-07-08, Version 1.3: CPU stats
317 * Collecting CPU statistics now
319 2004-07-12, Version 1.2: Using syslog
320 * collectd is now using the syslog facility to report errors, warnings
322 * The default directory is now /var/db/collectd
324 2004-07-10, Version 1.1: Minor changes
325 * Nothing really usefull to say ;)
327 2004-07-09, Version 1.0: Initial Version
328 * The following modules are provided:
