1 * apache plugin: Support for lighttpd's `BusyServers' (aka.
2 connections) field was added by Florent Monbillard.
4 2007-02-11, Version 3.11.2
5 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
6 NULL-pointer may have been passed to `printf' which causes a
7 segfault with some libcs.
9 2007-02-10, Version 3.11.1
10 * df plugin: Some wrong defines have been fixed so the plugin works
11 under Solaris again.
12 * dns plugin: The usage of a struct has been fixed to work with
13 non-GNU libcs.
14 * processes plugin: Some missing defines have been added so the plugin
15 compiles cleanly under FreeBSD and presumably other UNIXes.
17 2006-12-22, Version 3.11.0
18 * collectd: The new command line option `-P' makes it easier for
19 distributors to change the location of PID-files.
20 * collectd: The daemon shuts down faster now which makes it easier to
21 write init.d-scripts for it.
22 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
23 caused problems every now and then.
24 * df plugin: New config options allow to ignore certain mountpoints,
25 filesystem types or devices.
26 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
27 and interprets it. It collects traffic as well as qtype, opcode and
28 rcode counts.
29 * email plugin: Sebastian Harl has contributed this plugin which
30 counts received mails in categories (e. g. ham, spam, virus), spam
31 score (as given by SpamAssassin) and check types.
32 * mbmon plugin: Flavio Stanchina has contributed this plugin which
33 uses `mbmon' to gather information from sensors on the motherboard.
34 * processes plugin: Collect detailed statistics for configured
35 processes, that's process and thread count, CPU usage, resident
36 segment size and pagefaults.
37 * multimeter plugin: Peter Holik contributed a new plugin which
38 queries multimeters.
39 * sensors plugin: Lubos Stanek has put much effort into improving this
40 plugin, including `extended naming', collection of voltage values
41 and the possibility to ignore certain values.
43 2006-12-21, Version 3.10.4
44 * Max Kellermann has identified a bug in the server routine: When
45 opening a socket fails the daemon will (re)try opening the socket in
46 an endless loop, ultimately leading to a `EMFILE' error.
48 2006-11-04, Version 3.10.3
49 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
50 ntpd's reply was sent in more than one packet, the buffer size was
51 calculated incorrectly, resulting in the reading of uninitialized or
52 freed memory.
54 2006-11-01, Version 3.10.2
55 * The sample config file has been improved.
56 * Errors in the manpages have been corrected.
57 * The ping-plugin now adds hosts during initialization, not during
58 startup. This speeds up starup when no network connectivity is
59 available. Also, the hosts are being added later when the network is
60 available.
61 * Improved BSD-support for the df-plugin.
62 * Fixed syntax errors in the swap-plugin for Mac OS X.
63 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
64 plugin.
65 * Don't disable the mysql-plugin if connecting to the database fails
66 during initialization. Instead, try again in increasing intervals.
68 2006-07-19, Version 3.10.1
69 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
70 the apcups cannot be reached, unconnected sockets will pile up and
71 eventually lead to `Too many open files' errors.
73 2006-07-09, Version 3.10.0
74 * The `disk' plugin has been ported to Darwin.
75 * The `battery' plugin should work on many Apple computers now.
76 * The `traffic' plugin can now ignore certain interfaces. Also,
77 statistics for sent/received packets and errors have been added.
78 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
79 to Anthony Gialluca for contributing this plugin and providing me
80 with a test environment :)
81 * A plugin for moniroting an NTP instance and the local clock drift
82 has been added.
84 2006-06-25, Version 3.9.4
85 * The Solaris code in the `swap' plugin has been changed to reflect
86 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
87 working this out.
88 * The debugging system has been fixed to work with the Sun libc.
89 * When built without librrd the variable `operating_mode' could be
90 uninitialized. Thanks to David Elliot for reporting the bug.
92 2006-06-01, Version 3.9.3
93 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
94 operating systems also profit from the changes, but I wasn't able to
95 check that.
96 * Changed the build system to find the netinet-includes under FreeBSD
97 and therefore successfully build the `liboping' library there.
99 2006-05-09, Version 3.9.2
100 * Applied a patch to the `liboping' library. Due to a bug in the
101 sequence checking the `ping' plugin stopped working after
102 approximately 7.6 days.
104 2006-05-09, Version 3.8.5
105 * Applied a patch to the `liboping' library. Due to a bug in the
106 sequence checking the `ping' plugin stopped working after
107 approximately 7.6 days.
109 2006-04-21, Version 3.9.1
110 * Build issues with Solaris and possible other architectures have been
111 resolved.
112 * Problems when building the `apache'-plugin without `libcurl' have
113 been resolved.
114 * A bug in the `ping' plugin has been fixed. Sorry folks.
116 2006-04-02, Version 3.9.0
117 * A plugin to monitor the Apache webserver has been added.
118 <http://httpd.apache.org/>
119 * A plugin to collect statistics about virtual servers using VServer.
120 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
121 this plugin :)
122 * A plugin for wireless LAN cards has been added. It monitors signal
123 strength, link quality and noise ratio..
124 * A plugin for Apple hardware sensors has been added.
125 * An option to compile collectd with different `step' and `hearbeat'
126 settings has been added. The size of RRAs is no longer static but
127 calculated based on the settings for `step' and `width'.
128 * The `ping' plugin can now be configured to use a certain TTL.
129 * A plugin to monitor the hardware sensors of Apple computers has been
130 added.
131 * The plugins `cpu', `memory', `processes' and `traffic' have been
132 ported to Mach/Darwin (Mac OS X).
133 * The `log mode' has been contributed by Christophe Kalt. It writes
134 the data into text files rather than RRD files.
136 2006-04-09, Version 3.8.4
137 * Applied patch by Vincent Stehlé which improves the disk-name
138 resolution in the `hddtemp' plugin for Linux systems.
140 2006-04-02, Version 3.8.3
141 * Applied a patch by James Byers: The MySQL plugin was not working
142 with MySQL 5.0.2 or later.
144 2006-03-14, Version 3.8.2
145 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
146 the GNU libc, because it points to `/etc/fstab' rather than
147 `/etc/mtab'.
149 2006-03-13, Version 3.8.1
150 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
151 * Fixes in the debian `postinst' and `init.d' scripts.
153 2006-03-09, Version 3.8.0
154 * The `ping' plugin no longer uses `libping' but a self written
155 library named `liboping'. With this library it's possible to ping
156 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
158 2006-02-18, Version 3.7.2
159 * A simple bug in the `battery' plugin has been fixed. It should now
160 work with ACPI based batteries as well. Thankt to Sebastian for
161 fixing this.
162 * Fixing a bug that prevented collectd to be built without librrd.
163 Thanks to Werner Heuser for reporting it.
165 2006-02-04, Version 3.7.1
166 * The new network code has been improved to build with older versions
167 of glibc.
168 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
169 to Tommie Gannert for this patch.
171 2006-01-30, Version 3.7.0
172 * The `battery' plugin has been added. It collects information about
173 laptop batteries..
174 * The MySQL plugin has been improved: It now writes two more RRD
175 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
176 * The `cpufreq' plugin now reads another file since the file it did
177 read so far causes much overhead in the kernel. Also, you need root
178 to read the old file, but not to read the new one.
179 * The `hddtemp' plugin can now be configured to connect to another
180 address and/or port than localhost.
181 * The `df' plugin now prefers `statvfs' over `statfs'.
182 * The network code has been rewritten. collectd now supports unicast
183 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
184 be set in the configfile.
186 2006-01-24, Version 3.6.2
187 * Due to a bug in the configfile handling collectd wouldn't start in
188 client mode. This released fixes this.
190 2006-01-20, Version 3.6.1
191 * Due to a bug in `configure.in' all modules and the binary were
192 linked against `libmysqlclient'. This issue is solved by this
193 release.
195 2006-01-17, Version 3.6.0
196 * A config file has been added. This allows for loading only specific
197 plugins.
198 * A `df' plugin has been added.
199 * A `mysql' plugin has been added.
200 * The `ping' plugin doesn't entirely give up hope when a socket error
201 occured, but will back of and increase the intervals between tries.
203 2006-01-21, Version 3.5.2
204 * Fixed yet another bug in the signal handling.. Stupid typo..
205 * Improved the ping plugin to not give up on socket errors (backport
206 from 3.6.0).
208 2005-12-18, Version 3.5.1
209 * The PID-file is now deleted correctly when shutting down the daemon.
210 * SIGINT and SIGTERM are now handled correctly.
212 2005-12-16, Version 3.5.0 (Revision 326)
213 * A bug in the `load' module under Solaris has been fixed.
214 * The `users' module has been contributed by Sebastian Harl. It counts
215 currently logged in users.
216 * The CPU module now works under FreeBSD without the use of
217 `libstatgrab', however SMP support is missing.
218 * The default directories for the RRD files and the PID file now
219 depend on the compile time setting of `localstatedir'.
221 2005-11-15, Version 3.4.0 (Revision 236)
222 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
223 from gentoo's bugzilla for writing the patch.
224 * The build dependency for librrd has been removed. Binaries built
225 without librrd are client-only and will multicast their value as
226 with the `-c' argument.
227 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
228 * The newly introduced `-f' switch prevents daemon initialization
229 (forking, closing standard filehandles, etc.) Thanks to Alvaro
230 Barcellos for this patch.
232 2005-11-04, Version 3.3.0 (Revision 216)
233 * New modules have been added:
234 - `serial', for monitoring traffic on the serial interfaces
235 - `nfs', for graphing NFS procedure calls
236 - `tape', traffic from/to tape devices
237 * The the memory.rrd now accepts more than 4Gig of memory.
239 2005-10-26, Version 3.2.0 (Revision 200)
240 * Support for graphing the processes has been added (thanks to Lyonel
241 Vincent)
242 * If reading from hddtemp failes collectd will increase the time
243 between polls up to one day.
244 * The init.d files have been improved.
245 * Problems with the spec file have been fixed.
247 2005-10-16, Version 3.1.0 (Revision 194)
248 * Added the `setsid' syscall to the startup code.
249 * Support for hddtemp has been added (thanks to Vincent Stehlé)
251 2005-09-30, Version 3.0.0 (Revision 184)
252 * The ability to send/receive data to/from the network (think
253 multicast) has been added.
254 * Modules have been split up into shared libraries can be loaded at
255 runtime. The biggest advantage is that the core program doesn't need
256 to be linked against an external library.
257 * A patch by George Kargiotakis has been applied: It fixes the sensors
258 behaviour then more than one sensor is being queried.
260 2005-09-16, Version 2.1.0 (Revision 172)
261 * A module for swap statistics has been added.
263 2005-09-09, Version 2.0.0 (Revision 135)
264 * Filenames can no longer be configured at program startup. The only
265 options as of this version are the directory and ping hosts.
266 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
267 Soft-IRQ statistics are added to `System'.
268 * Diskstats now collect read and write bytes, not sectors.
269 * Ping statistics can now be collected for more than one host. There
270 is no default any more: If no host is given no host will be pinged.
271 * A self-written patch for libping has been applied so it builds
272 cleanly.
274 2005-09-01, Version 1.8.1 (Revision 123)
275 * Much improved configure-script: libraries and features may now be
276 disabled.
277 * More detailed warnings/error messages when RRD update failes.
279 2005-08-29, Version 1.8.0:
280 * Support for collecting disk statistics under Solaris.
282 2005-08-25, Version 1.7.0:
283 * Support for libstatgrab[1] for load, memory usage and network
284 traffic. CPU- and disk-usage are not (yet) supported, since
285 libstatgrab returns insufficient information. I will contact the
286 authors.
287 * Improved the CPU-initialization code for Solaris. Apparently CPUs
288 aren't neccessarily counted linear which is now handled correctly.
289 [1]: http://www.i-scream.org/libstatgrab/
291 2005-08-21, Version 1.6.0:
292 * Basic support for Solaris: System load and cpu-usage can be
293 collected unter Solaris, too. Other stats will follow later.
294 * Many fixes in the autoconf-script
295 * Collection/Museum scripts have been added unter contrib/museum
296 * collectd may now be started in unprivileged mode, though ping
297 statistics will not work.
299 2005-07-17, Version 1.5.1:
300 * Diskstats-RRDs now use major/minor for naming. Some systems have
301 weird strings as disk-names..
303 2005-07-17, Version 1.5:
304 * A new module, diskstats, has been added. It collects information
305 about the disks and partitions.
307 2005-07-11, Version 1.4.2:
308 * The meminfo mofule has been changed to work with more platforms
309 and/or kernel versions.
311 2005-07-10, Version 1.4.1: Correct traffic stats
312 * The traffic rrd-file is now created with DS-type `COUNTER' which I
313 forgot to correct when I changed that module.
315 2005-07-09, Version 1.4: More traffic stats
316 * Traffic is now collected for all interfaces that can be found
317 * Temperature-statistics are read from lm-sensors if available
319 2005-07-08, Version 1.3: CPU stats
320 * Collecting CPU statistics now
322 2004-07-12, Version 1.2: Using syslog
323 * collectd is now using the syslog facility to report errors, warnings
324 and the like..
325 * The default directory is now /var/db/collectd
327 2004-07-10, Version 1.1: Minor changes
328 * Nothing really usefull to say ;)
330 2004-07-09, Version 1.0: Initial Version
331 * The following modules are provided:
332 * Load average
333 * Ping time
334 * Traffic
335 * Memory info
