1 2006-12-22, Version 3.11.0
2 * collectd: The new command line option `-P' makes it easier for
3 distributors to change the location of PID-files.
4 * collectd: The daemon shuts down faster now which makes it easier to
5 write init.d-scripts for it.
6 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
7 caused problems every now and then.
8 * df plugin: New config options allow to ignore certain mountpoints,
9 filesystem types or devices.
10 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
11 and interprets it. It collects traffic as well as qtype, opcode and
12 rcode counts.
13 * email plugin: Sebastian Harl has contributed this plugin which
14 counts received mails in categories (e. g. ham, spam, virus), spam
15 score (as given by SpamAssassin) and check types.
16 * mbmon plugin: Flavio Stanchina has contributed this plugin which
17 uses `mbmon' to gather information from sensors on the motherboard.
18 * processes plugin: Collect detailed statistics for configured
19 processes, that's process and thread count, CPU usage, resident
20 segment size and pagefaults.
21 * multimeter plugin: Peter Holik contributed a new plugin which
22 queries multimeters.
23 * sensors plugin: Lubos Stanek has put much effort into improving this
24 plugin, including `extended naming', collection of voltage values
25 and the possibility to ignore certain values.
27 2006-12-21, Version 3.10.4
28 * Max Kellermann has identified a bug in the server routine: When
29 opening a socket fails the daemon will (re)try opening the socket in
30 an endless loop, ultimately leading to a `EMFILE' error.
32 2006-11-04, Version 3.10.3
33 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
34 ntpd's reply was sent in more than one packet, the buffer size was
35 calculated incorrectly, resulting in the reading of uninitialized or
36 freed memory.
38 2006-11-01, Version 3.10.2
39 * The sample config file has been improved.
40 * Errors in the manpages have been corrected.
41 * The ping-plugin now adds hosts during initialization, not during
42 startup. This speeds up starup when no network connectivity is
43 available. Also, the hosts are being added later when the network is
44 available.
45 * Improved BSD-support for the df-plugin.
46 * Fixed syntax errors in the swap-plugin for Mac OS X.
47 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
48 plugin.
49 * Don't disable the mysql-plugin if connecting to the database fails
50 during initialization. Instead, try again in increasing intervals.
52 2006-07-19, Version 3.10.1
53 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
54 the apcups cannot be reached, unconnected sockets will pile up and
55 eventually lead to `Too many open files' errors.
57 2006-07-09, Version 3.10.0
58 * The `disk' plugin has been ported to Darwin.
59 * The `battery' plugin should work on many Apple computers now.
60 * The `traffic' plugin can now ignore certain interfaces. Also,
61 statistics for sent/received packets and errors have been added.
62 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
63 to Anthony Gialluca for contributing this plugin and providing me
64 with a test environment :)
65 * A plugin for moniroting an NTP instance and the local clock drift
66 has been added.
68 2006-06-25, Version 3.9.4
69 * The Solaris code in the `swap' plugin has been changed to reflect
70 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
71 working this out.
72 * The debugging system has been fixed to work with the Sun libc.
73 * When built without librrd the variable `operating_mode' could be
74 uninitialized. Thanks to David Elliot for reporting the bug.
76 2006-06-01, Version 3.9.3
77 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
78 operating systems also profit from the changes, but I wasn't able to
79 check that.
80 * Changed the build system to find the netinet-includes under FreeBSD
81 and therefore successfully build the `liboping' library there.
83 2006-05-09, Version 3.9.2
84 * Applied a patch to the `liboping' library. Due to a bug in the
85 sequence checking the `ping' plugin stopped working after
86 approximately 7.6 days.
88 2006-05-09, Version 3.8.5
89 * Applied a patch to the `liboping' library. Due to a bug in the
90 sequence checking the `ping' plugin stopped working after
91 approximately 7.6 days.
93 2006-04-21, Version 3.9.1
94 * Build issues with Solaris and possible other architectures have been
95 resolved.
96 * Problems when building the `apache'-plugin without `libcurl' have
97 been resolved.
98 * A bug in the `ping' plugin has been fixed. Sorry folks.
100 2006-04-02, Version 3.9.0
101 * A plugin to monitor the Apache webserver has been added.
102 <http://httpd.apache.org/>
103 * A plugin to collect statistics about virtual servers using VServer.
104 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
105 this plugin :)
106 * A plugin for wireless LAN cards has been added. It monitors signal
107 strength, link quality and noise ratio..
108 * A plugin for Apple hardware sensors has been added.
109 * An option to compile collectd with different `step' and `hearbeat'
110 settings has been added. The size of RRAs is no longer static but
111 calculated based on the settings for `step' and `width'.
112 * The `ping' plugin can now be configured to use a certain TTL.
113 * A plugin to monitor the hardware sensors of Apple computers has been
114 added.
115 * The plugins `cpu', `memory', `processes' and `traffic' have been
116 ported to Mach/Darwin (Mac OS X).
117 * The `log mode' has been contributed by Christophe Kalt. It writes
118 the data into text files rather than RRD files.
120 2006-04-09, Version 3.8.4
121 * Applied patch by Vincent Stehlé which improves the disk-name
122 resolution in the `hddtemp' plugin for Linux systems.
124 2006-04-02, Version 3.8.3
125 * Applied a patch by James Byers: The MySQL plugin was not working
126 with MySQL 5.0.2 or later.
128 2006-03-14, Version 3.8.2
129 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
130 the GNU libc, because it points to `/etc/fstab' rather than
131 `/etc/mtab'.
133 2006-03-13, Version 3.8.1
134 * Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
135 * Fixes in the debian `postinst' and `init.d' scripts.
137 2006-03-09, Version 3.8.0
138 * The `ping' plugin no longer uses `libping' but a self written
139 library named `liboping'. With this library it's possible to ping
140 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
142 2006-02-18, Version 3.7.2
143 * A simple bug in the `battery' plugin has been fixed. It should now
144 work with ACPI based batteries as well. Thankt to Sebastian for
145 fixing this.
146 * Fixing a bug that prevented collectd to be built without librrd.
147 Thanks to Werner Heuser for reporting it.
149 2006-02-04, Version 3.7.1
150 * The new network code has been improved to build with older versions
151 of glibc.
152 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
153 to Tommie Gannert for this patch.
155 2006-01-30, Version 3.7.0
156 * The `battery' plugin has been added. It collects information about
157 laptop batteries..
158 * The MySQL plugin has been improved: It now writes two more RRD
159 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
160 * The `cpufreq' plugin now reads another file since the file it did
161 read so far causes much overhead in the kernel. Also, you need root
162 to read the old file, but not to read the new one.
163 * The `hddtemp' plugin can now be configured to connect to another
164 address and/or port than localhost.
165 * The `df' plugin now prefers `statvfs' over `statfs'.
166 * The network code has been rewritten. collectd now supports unicast
167 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
168 be set in the configfile.
170 2006-01-24, Version 3.6.2
171 * Due to a bug in the configfile handling collectd wouldn't start in
172 client mode. This released fixes this.
174 2006-01-20, Version 3.6.1
175 * Due to a bug in `configure.in' all modules and the binary were
176 linked against `libmysqlclient'. This issue is solved by this
177 release.
179 2006-01-17, Version 3.6.0
180 * A config file has been added. This allows for loading only specific
181 plugins.
182 * A `df' plugin has been added.
183 * A `mysql' plugin has been added.
184 * The `ping' plugin doesn't entirely give up hope when a socket error
185 occured, but will back of and increase the intervals between tries.
187 2006-01-21, Version 3.5.2
188 * Fixed yet another bug in the signal handling.. Stupid typo..
189 * Improved the ping plugin to not give up on socket errors (backport
190 from 3.6.0).
192 2005-12-18, Version 3.5.1
193 * The PID-file is now deleted correctly when shutting down the daemon.
194 * SIGINT and SIGTERM are now handled correctly.
196 2005-12-16, Version 3.5.0 (Revision 326)
197 * A bug in the `load' module under Solaris has been fixed.
198 * The `users' module has been contributed by Sebastian Harl. It counts
199 currently logged in users.
200 * The CPU module now works under FreeBSD without the use of
201 `libstatgrab', however SMP support is missing.
202 * The default directories for the RRD files and the PID file now
203 depend on the compile time setting of `localstatedir'.
205 2005-11-15, Version 3.4.0 (Revision 236)
206 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
207 from gentoo's bugzilla for writing the patch.
208 * The build dependency for librrd has been removed. Binaries built
209 without librrd are client-only and will multicast their value as
210 with the `-c' argument.
211 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
212 * The newly introduced `-f' switch prevents daemon initialization
213 (forking, closing standard filehandles, etc.) Thanks to Alvaro
214 Barcellos for this patch.
216 2005-11-04, Version 3.3.0 (Revision 216)
217 * New modules have been added:
218 - `serial', for monitoring traffic on the serial interfaces
219 - `nfs', for graphing NFS procedure calls
220 - `tape', traffic from/to tape devices
221 * The the memory.rrd now accepts more than 4Gig of memory.
223 2005-10-26, Version 3.2.0 (Revision 200)
224 * Support for graphing the processes has been added (thanks to Lyonel
225 Vincent)
226 * If reading from hddtemp failes collectd will increase the time
227 between polls up to one day.
228 * The init.d files have been improved.
229 * Problems with the spec file have been fixed.
231 2005-10-16, Version 3.1.0 (Revision 194)
232 * Added the `setsid' syscall to the startup code.
233 * Support for hddtemp has been added (thanks to Vincent Stehlé)
235 2005-09-30, Version 3.0.0 (Revision 184)
236 * The ability to send/receive data to/from the network (think
237 multicast) has been added.
238 * Modules have been split up into shared libraries can be loaded at
239 runtime. The biggest advantage is that the core program doesn't need
240 to be linked against an external library.
241 * A patch by George Kargiotakis has been applied: It fixes the sensors
242 behaviour then more than one sensor is being queried.
244 2005-09-16, Version 2.1.0 (Revision 172)
245 * A module for swap statistics has been added.
247 2005-09-09, Version 2.0.0 (Revision 135)
248 * Filenames can no longer be configured at program startup. The only
249 options as of this version are the directory and ping hosts.
250 * CPU statistics now include Wait-IO. If privided under Linux IRQ and
251 Soft-IRQ statistics are added to `System'.
252 * Diskstats now collect read and write bytes, not sectors.
253 * Ping statistics can now be collected for more than one host. There
254 is no default any more: If no host is given no host will be pinged.
255 * A self-written patch for libping has been applied so it builds
256 cleanly.
258 2005-09-01, Version 1.8.1 (Revision 123)
259 * Much improved configure-script: libraries and features may now be
260 disabled.
261 * More detailed warnings/error messages when RRD update failes.
263 2005-08-29, Version 1.8.0:
264 * Support for collecting disk statistics under Solaris.
266 2005-08-25, Version 1.7.0:
267 * Support for libstatgrab[1] for load, memory usage and network
268 traffic. CPU- and disk-usage are not (yet) supported, since
269 libstatgrab returns insufficient information. I will contact the
270 authors.
271 * Improved the CPU-initialization code for Solaris. Apparently CPUs
272 aren't neccessarily counted linear which is now handled correctly.
273 [1]: http://www.i-scream.org/libstatgrab/
275 2005-08-21, Version 1.6.0:
276 * Basic support for Solaris: System load and cpu-usage can be
277 collected unter Solaris, too. Other stats will follow later.
278 * Many fixes in the autoconf-script
279 * Collection/Museum scripts have been added unter contrib/museum
280 * collectd may now be started in unprivileged mode, though ping
281 statistics will not work.
283 2005-07-17, Version 1.5.1:
284 * Diskstats-RRDs now use major/minor for naming. Some systems have
285 weird strings as disk-names..
287 2005-07-17, Version 1.5:
288 * A new module, diskstats, has been added. It collects information
289 about the disks and partitions.
291 2005-07-11, Version 1.4.2:
292 * The meminfo mofule has been changed to work with more platforms
293 and/or kernel versions.
295 2005-07-10, Version 1.4.1: Correct traffic stats
296 * The traffic rrd-file is now created with DS-type `COUNTER' which I
297 forgot to correct when I changed that module.
299 2005-07-09, Version 1.4: More traffic stats
300 * Traffic is now collected for all interfaces that can be found
301 * Temperature-statistics are read from lm-sensors if available
303 2005-07-08, Version 1.3: CPU stats
304 * Collecting CPU statistics now
306 2004-07-12, Version 1.2: Using syslog
307 * collectd is now using the syslog facility to report errors, warnings
308 and the like..
309 * The default directory is now /var/db/collectd
311 2004-07-10, Version 1.1: Minor changes
312 * Nothing really usefull to say ;)
314 2004-07-09, Version 1.0: Initial Version
315 * The following modules are provided:
316 * Load average
317 * Ping time
318 * Traffic
319 * Memory info
