1 2009-01-02, Version 4.4.5
2 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3 file may be in both locations, especially when the database was
4 installed in a non-standard path. Thanks to Dusty Doris for
6 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
7 Solaris, in the configure script automatically.
8 * collectd.conf(5): Various fixes and clarifications.
9 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
10 portability problems, especially for Solaris.
11 * dns plugin: Fix a portability problem with NetBSD.
12 * network plugin: Fix the handling of `type' in the network protocol.
13 Due to a programming mistake, only 4 or 8 bytes would be copied to a
14 much larger buffer. This caused the `type' to be transferred much
15 more often than necessary. In some cases, e. g. the `cpu' and
16 `cpufreq' plugins being used at the same time, data may be corrupted
17 in those files. Thanks to Bruno Prémont for debugging and reporting
19 * unixsock plugin: Make sure the initialization function is run only
20 once. This resolves a file descriptor leak under systems which run
21 the initialization more than once, such as Solaris.
23 2008-10-16, Version 4.4.4
24 * build system: Change `--enable-<plugin>' to abort with an error if
25 dependencies are not met. Thanks to Bruno Prémont for the patch.
26 Also, the poisoning of various string functions has been restricted
28 * collectd: Fix a memory leak in the global value cache. With every
29 *missing* value a couple of bytes would be leaked. Another memory
30 leak in the configuration handling code has been fixed. Thanks to
31 Niraj Tolia for reporting these issues.
32 * collectd: Fix an off-by-one error in the ignorelist functionality.
33 When using regular expressions, the last character would be missing,
34 possibly matching differently from what one would expect.
35 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
37 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
38 Linzberger for reporting the bug.
39 * network plugin: Fix a memory leak in the configuration handling
40 code. Thanks to Niraj Tolia for reporting this issue.
41 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
42 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
43 problems with some `libc's. Thanks to Matthias Lay for reporting the
46 2008-09-01, Version 4.4.3
47 * collectd: Fix a memory leak in the threshold checking code.
48 * memcached plugin: Fix a too short timeout and a related file
50 * memory plugin: A typo in the libstatgrab code has been fixed.
51 * snmp plugin: Fix a possible memory leak.
53 2008-07-15, Version 4.4.2
54 * build system: Use pkg-config to detect the upsclient library.
55 * collectd: Try even harder to determine the endianess of the
56 architecture collectd is being built on.
57 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
59 * dns plugin: Fix compilation errors with BIND versions 19991001
61 * network plugin: Bugfix in the init routine: The init function
62 cleared a buffer regardless of its contents. This could lead to lost
64 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
65 * vserver plugin: Remove usage of the thread-unsafe `readdir'
67 * wireless plugin: Work around incorrect noise and power values
68 returned by some broken drivers.
70 2008-06-03, Version 4.4.1
71 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
72 to kyrone for reporting this.
73 * collectd: Fixed min/max output in notifications generated by
75 * collectd-nagios: Fix the protocol used to communicate with the
77 * perl plugin: Fail noisily, but don't shutdown the daemon, if
78 initialization has errors. An issue with Perl 5.10 has been fixed.
79 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
80 René Rebe and Siegmund Gorr for reporting this.
82 2008-05-06, Version 4.4.0
83 * collectd: Internal code cleanups.
84 * collectd: Added support for a `Flush' command in the unixsock and
85 exec plugins. This command can be used to force a plugin (or all) to
86 flush its values to disk.
87 * collectd: Thresholds can now be configured to apply to one data
88 source only, making it possible to configure different thresholds
90 * apache, nginx plugins: Added the possibility to disable host and/or
92 * ascent plugin: The new ascent plugin reads and parses the statistics
93 page of an Ascent server.
94 * cpu plugin: Support for the statgrab library has been added.
95 * disk plugin: The possibility to ignore certain disks or collect only
96 specific disks has been added.
97 * disk plugin: Support for the statgrab library has been added.
98 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
99 sensor values via IPMI, the intelligent platform management
101 * iptables plugin: The iptc library that is used by the iptables
102 plugin has been added to the distribution, because it is not
103 provided by all distributions and removed from at least one.
104 * powerdns plugin: The new powerdns plugin reads statistics from an
105 authoritative or a recursing PowerDNS name server.
106 * rrdtool plugin: The size of the files generated with the default
107 configuration has been decreased.
108 * tail plugin: The new tail plugin can be used to gather statistics by
109 continuously reading from log files.
110 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
111 TeamSpeak2 server and collects statistics about the number of users
112 and number of channels.
113 * users plugin: Support for the statgrab library has been added.
114 * vmem plugin: The new vmem plugin collects very detailed statistics
115 about the virtual memory subsystem of Linux.
117 2008-08-30, Version 4.3.4
118 * Build system: Improved detection of and linking with the statgrab
120 * collectd: Portability fixes, especially to determine endianess more
122 * Various plugins: Fix format strings.

124 again has been applied.
125 * memcached plugin: Fix a too short timeout and a related file
127 * memory plugin: A typo in the libstatgrab code has been fixed.
128 * network plugin: A fix in the initialization function solves problems
130 * nginx plugin: A thread-unsafe function has been replaced.
131 * vserver plugin: A thread-unsafe function has been replaced.
132 * wireless plugin: A work-around for broken wireless drivers has been
135 2008-04-22, Version 4.3.3
136 * build system: Improved detection of several libraries, especially if
137 they are in non-standard paths.
138 * build system: Portability fixes: Automatically define "_REENTRANT"
139 if the libc expects it.
140 * collectd: Error and warning messages have been improved.
141 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
143 * apache plugin: Allocate new memory when reading a webpage instead of
144 using a buffer of static size.
145 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
147 * hddtemp plugin: Error and warning messages have been improved.
148 * sensors plugin: Fix sensor collection for some chip types.
150 2008-03-29, Version 4.3.2
151 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
152 `Persist' threshold options.
153 * collectd: Fix handling of missing values in the global value cache.
154 * collectd: Improved error messages when parsing the configuration.

156 * unixsock plugin: Fix mixed input and output operation on streams.
157 * wireless plugin: Fix reading noise value.
159 2008-03-05, Version 4.3.1
160 * exec plugin: Set supplementary group IDs.
162 + Use `memcpy' when constructing/parsing a package to avoid
163 alignment problems on weird architectures, such as Sparc.
164 + Translate doubles to/from the x86 byte representation to ensure
165 cross-platform compatibility.
166 * ping plugin: Correct the handling of the `TTL' setting.
167 * swap plugin: Reapply a patch for Solaris.
168 * tcpconns plugin: Portability improvements.
170 2008-02-18, Version 4.3.0
171 * collectd: Notifications have been added to the daemon. Notifications
172 are status messages that may be associated with a data instance.
173 * collectd: Threshold checking has been added to the daemon. This
174 means that you can configure threshold values for each data
175 instance. If this threshold is exceeded a notification will be
177 * collectd: The new `FQDNLookup' option tells the daemon to use the
178 full qualified domain name as the hostname, not just the host part
179 es returned by `gethostname(2)'.
180 * collectd: Support for more than one `TypesDB' file has been added.
181 This is useful when one such file is included in a package but one
182 wants to add custom type definitions.
183 * collectd: The `Include' config option has been expanded to handle
184 entire directories and shell wildcards.
185 * collectdmon: The new `collectdmon' binary detects when collectd
186 terminates and automatically restarts it again.
187 * csv plugin: The CSV plugin is now able to store counter values as a
188 rate, using the `StoreRates' configuration option.
189 * exec plugin: Handling of notifications has been added and the
190 ability to pass arguments to the executed programs has been added.
191 * hddtemp plugin: The new `TranslateDevicename' option lets you
192 disable the translation from device names to major-minor-numbers.
193 * logfile plugin: Handling of notifications has been added.
194 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
195 domain name lookups in this plugin.
196 * perl plugin: Many internal changes added support for handling multiple
197 threads making the plugin reasonably usable inside collectd. The API has
198 been extended to support notifications and export global variables to
199 Perl plugins; callbacks now have to be identified by name rather than a
200 pointer to a subroutine. The plugin is no longer experimental.
201 * uuid plugin: The new UUID plugin sets the hostname to an unique
202 identifier for this host. This is meant for setups where each client
203 may migrate to another physical host, possibly going through one or
204 more name changes in the process. Thanks to Richard Jones from
205 Red Hat's Emerging Technology group for this plugin.
206 * libvirt: The new libvirt plugin uses the `libvirt' library to query
207 CPU, disk and network statistics about guest systems on the same
208 physical server. Thanks to Richard Jones from Red Hat's Emerging
209 Technology group for this plugin.
211 2008-04-22, Version 4.2.7
212 * build system: Improved detection of several libraries, especially if
213 they are in non-standard paths.
214 * build system: Portability fixes: Automatically define "_REENTRANT"
215 if the libc expects it.
216 * collectd: Error and warning messages have been improved.
217 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
219 * apache plugin: Allocate new memory when reading a webpage instead of
220 using a buffer of static size.
221 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
223 * hddtemp plugin: Error and warning messages have been improved.
224 * sensors plugin: Fix sensor collection for some chip types.

229 * unixsock plugin: Fix mixed input and output operation on streams.
230 * wireless plugin: Fix reading noise value.
232 2008-03-04, Version 4.2.5
233 * apache plugin: Improved initialization and error messages.
234 * exec plugin: Set supplementary group IDs.
236 + Create separate threads for reading from the socket and parsing
237 and dispatching incoming packets. Versions prior to this may have
238 problems in high-load situations, where the socket receive buffers
239 overflows, resulting in gaps in the data.
240 + Use `memcpy' when constructing/parsing a package to avoid
241 alignment problems on weird architectures, such as Sparc.
242 + Translate doubles to/from the x86 byte representation to ensure
243 cross-platform compatibility.
244 * ping plugin: Correct the handling of the `TTL' setting.
245 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
246 * swap plugin: Reapply a patch for Solaris.
247 * tcpconns plugin: Portability improvements.
249 2008-01-21, Version 4.2.4
250 * unixsock plugin: A bug in the unixsock plugin caused it not to set
251 the permission on the socket as documented in the manpage. Thanks to
252 Evgeny Chukreev for fixing this issue.
253 * collectd: The documentation has been improved.
255 2007-12-28, Version 4.2.3
256 * sensors plugin: Updated the plugin to build and work with version 3
257 of the libsensors library.
259 2007-12-15, Version 4.2.2
260 * nginx plugin: Incorrect comparison of strings lead to a segfault
261 when using the plugin. Thanks to Saulius Grigaliunas for fixing
263 * logfile plugin: The config option `Timestamp' was handled
264 incorrectly and basically always active. Thanks to Luke Heberling
267 2007-11-08, Version 4.2.1
268 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
270 * snmp plugin: Fix a memory leak.
272 2007-10-27, Version 4.2.0
273 * collectd: The new config option `Include' lets you include other
274 configfiles and thus split up your config into smaller parts. This
275 may be especially interesting for the snmp plugin to keep the data
276 definitions separate from the host definitions.
277 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
278 (number of connections, octets and packets for each service and
279 destination). Thanks to Sebastian Harl for this plugin.
280 * memcached plugin: The new `memcached' plugin connects to a memcached
281 daemon process and collects statistics of this distributed caching
282 system. Thanks to Antony Dovgal for contributing this plugin.
283 * nginx plugin: The new `nginx' plugin reads the status page of an
284 nginx daemon and saves the handled connections and requests.
285 * perl plugin: Many changes, including the added `EnableDebugger'
286 config option which lets you debug your Perl plugins more easily.
287 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
288 be more thread-safe otherwise by locking calls to the library.
289 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
290 correct the values returned by SNMP-agents. If a <data> block is
291 defined as `table' the instance is now optional. The sequence number
292 is used as the type-instance in this case. The new `InstancePrefix'
293 option allows to add arbitrary prefixes to the type-instance.
294 * tcpconns plugin: The new `tcpconns' plugin collects the number of
295 certain TCP connections and what state they're in. This can be used
296 to see how many connections your FTP server has to handle or how
297 many outgoing connections your mailserver has open.
299 2008-01-11, Version 4.1.6
300 * unixsock plugin: A bug in the unixsock plugin caused it not to set
301 the permission on the socket as documented in the manpage. Thanks to
302 Evgeny Chukreev for fixing this issue.

313 it's in a non-standard location.
314 * Build system: A bug when parsing the argument for
315 `--with-libnetsnmp' has been fixed.
316 * collectd: Implement `strerror_r' if the libc doesn't provide it.
317 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
318 a deadlock or delay when shutting down the daemon.
319 * snmp plugin: Fix a memory leak.
321 2007-10-24, Version 4.1.3
322 * collectd: A build issue under Solaris has been resolved by renaming
324 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
325 be more thread-safe otherwise by locking calls to the library.
327 2007-09-28, Version 4.1.2
328 * apcups plugin: Fix reporting of the `load percent' data.
329 * wireless plugin: Correct the handling of cards returning signal and
330 noise quality as percentage.
331 * perl plugin: Fix a possible buffer overflow in get_module_name().
332 * build system: Further improve the detection of libraries.
333 * netlink plugin: Build issues under some older versions of the Linux
334 includes (i. e. Debian Sarge) have been fixed.

339 * Build system: The detection of `libnetlink' has been improved.
340 * collectd: The documentation has been fixed in numerous places.
341 * exec plugin: Setting the group under which to run a program has been
343 * collectd: The `sstrerror' function was improved to work correctly
344 with the broken GNU version of `strerror_r'.
345 * collectd: Write an error message to STDERR when loading of a plugin
347 * apcups plugin: Fix the `types' used to submit the values: They still
348 has an `apcups_' prefix which doesn't work anymore.
349 * rrdtool plugin: Create new RRD-files with the `begin' time set to
350 whatever the client thinks is `now'..
352 2007-09-01, Version 4.1.0
353 * Build system: The build system has been changed to automatically
354 disable all plugins, which are missing dependencies. The dependency
355 checking has been removed from the plugins themselves to remove
357 * Flexible interval: The interval of collected data is now sent along
358 with the data itself over the network, so that the interval-settings
359 of server and clients no longer needs to match.
360 * netlink plugin: The new `netlink' plugin connects to the Linux
361 kernel using a netlink socket and uses it to query information about
362 interfaces, qdiscs and classes.
363 * rrdtool plugin: The cache is now dumped to disk in an extra thread
364 to not block data collection.
365 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
366 network devices, such as switches, routers, thermometers, rack
367 monitoring servers, etc. The collectd-snmp(5) manpage documents this
369 * unixsock plugin: Added the `LISTVAL' command.
370 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
371 of music played with xmms.
373 2007-09-28, Version 4.0.9

377 * perl plugin: Fix a possible buffer overflow in get_module_name().
379 2007-09-12, Version 4.0.8
380 * collectd: The `sstrerror' function was improved to work correctly
381 with the broken GNU version of `strerror_r'.
382 * collectd: Write an error message to STDERR when loading of a plugin
384 * apcups plugin: Fix the `types' used to submit the values: They still
385 has an `apcups_' prefix which doesn't work anymore.
386 * rrdtool plugin: Create new RRD-files with the `begin' time set to
387 whatever the client thinks is `now'..
389 2007-08-26, Version 4.0.7
390 * documentation: Some typos have been fixed and some information has
392 * build system: Many fixes for detecting libraries in unusual places,
393 such as on RedHat systems. The affected libraries are `libcurl',
394 `libmysql', and `libupsclient'.
395 * network plugin: Allow the `Port' option to be specified as a number
396 (i. e. without quotes).
397 * nut plugin: A fix allows linking the nut plugin against
398 libupsclient, version >= 2.2.0.
399 * processes plugin: Fix a potential segmentation fault.
401 2007-07-30, Version 4.0.6
402 * sensors plugin: Fix the ignorelist functionality: Only the `type
403 instance' was used to match against the list, but the documentation
404 told otherwise. This release fixes the code, so it complies with the
406 * syslog plugin: Call `openlog' right when the plugin is loaded, so
407 configuration messages will end up in the logging facility.
408 * conrtib/fedora: The contributed specfile for Fedora has been
411 2007-07-05, Version 4.0.5
412 * Portability: More fixes for OpenBSD have been included.
414 2007-06-24, Version 4.0.4

425 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
426 initialized correctly.
427 * configure: Added `--with-nan-emulation' to aid cross compilation.
429 2007-06-12, Version 4.0.2
430 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
431 they're given in numerically form.
433 2007-06-07, Version 4.0.1
434 * iptables plugin: A bug in the configuration routine has been fixed.
435 Setting a comment in the configfile will no longer cause a
438 2007-06-03, Version 4.0.0
439 * collectd: The plugin-infrastructure has been changed to allow for
440 more types of plugins, namely `write' and `log' plugins.
441 * collectd: The read-function has been changed to read many plugins in
442 parallel, using threads. Thus, plugins generally need to use
443 thread-safe functions from now on.
444 * collectd: The '-t' command line options allows to perform syntax tests
445 of the configuration file and exit immediately.
446 * csv plugin: The new `csv' plugin handles output to `comma separated
448 * rrdtool plugin: The new `rrdtool' plugin handles output to
449 RRD-files. Data can be cached to combine multiple updates into one
450 write to increase IO-performance.
451 * network plugin: The new `network' plugin handles IO via the network.
452 It implements a different, much more extensible protocol which can
453 combine many values in one packet, decreasing the number of UDP-
454 packets being sent. It can read from and send to the network and
455 with the appropriate configuration even forward packets to other
457 * unixsock plugin: The new `unixsock' plugin provides an interface to
458 communicate with the daemon while it is running. Right now the
459 commands `GETVAL' and `PUTVAL' are implemented, but more are to
461 * perl plugin: The new `perl' plugin allows you to write extensions
462 for collectd in the scripting-language Perl.
463 * logfile plugin: The new `logfile' plugin writes logmessages to files
465 * syslog plugin: The new `syslog' plugin sends logmessages to the
466 system's syslog daemon.
467 * entropy plugin: The new `entropy' plugin collects the amount of
468 entropy currently being available to the system.
469 * exec plugin: The new `exec' plugin forks child processes and reads
470 back values provided by the forked processes.
471 * iptables plugin: The new `iptables' plugin reads counters from
472 iptables rules. Thanks to Sjoerd van der Berg for contributing this
474 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
475 to Peter Holik for contributing this plugin.
476 * nut plugin: The new `nut' plugin connects the upsd of the `network
477 ups tools' and reads information about the connected UPS.

479 connections) field was added by Florent Monbillard.
480 * collectd-nagios: The new `collectd-nagios' binary queries values
481 from collectd, parses them and exits according to Nagios-standards.
482 * manpages: The manpages have been improved a lot.
484 2007-09-28, Version 3.11.7
485 * wireless plugin: Correct the handling of cards returning signal and

495 were accounted as `zombies'.
497 2007-04-10, Version 3.11.4
498 * dns plugin: Change the order of includes to make the plugin compile
501 2007-03-30, Version 3.11.3
502 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
503 of the unused `COLLECT_KSTAT'.
505 2007-02-11, Version 3.11.2
506 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
507 NULL-pointer may have been passed to `printf' which causes a
508 segfault with some libcs.
510 2007-02-10, Version 3.11.1
511 * df plugin: Some wrong defines have been fixed so the plugin works
513 * dns plugin: The usage of a struct has been fixed to work with
515 * processes plugin: Some missing defines have been added so the plugin
516 compiles cleanly under FreeBSD and presumably other UNIXes.
518 2006-12-22, Version 3.11.0
519 * collectd: The new command line option `-P' makes it easier for
520 distributors to change the location of PID-files.
521 * collectd: The daemon shuts down faster now which makes it easier to
522 write init.d-scripts for it.
523 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
524 caused problems every now and then.
525 * df plugin: New config options allow to ignore certain mountpoints,
526 filesystem types or devices.
527 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
528 and interprets it. It collects traffic as well as qtype, opcode and
530 * email plugin: Sebastian Harl has contributed this plugin which
531 counts received mails in categories (e. g. ham, spam, virus), spam
532 score (as given by SpamAssassin) and check types.
533 * mbmon plugin: Flavio Stanchina has contributed this plugin which
534 uses `mbmon' to gather information from sensors on the motherboard.
535 * processes plugin: Collect detailed statistics for configured
536 processes, that's process and thread count, CPU usage, resident
537 segment size and pagefaults.
538 * multimeter plugin: Peter Holik contributed a new plugin which
540 * sensors plugin: Lubos Stanek has put much effort into improving this
541 plugin, including `extended naming', collection of voltage values
542 and the possibility to ignore certain values.
544 2006-12-21, Version 3.10.4
545 * Max Kellermann has identified a bug in the server routine: When
546 opening a socket fails the daemon will (re)try opening the socket in
547 an endless loop, ultimately leading to a `EMFILE' error.
549 2006-11-04, Version 3.10.3
550 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
551 ntpd's reply was sent in more than one packet, the buffer size was
552 calculated incorrectly, resulting in the reading of uninitialized or
555 2006-11-01, Version 3.10.2
556 * The sample config file has been improved.
557 * Errors in the manpages have been corrected.
558 * The ping-plugin now adds hosts during initialization, not during
559 startup. This speeds up startup when no network connectivity is
560 available. Also, the hosts are being added later when the network is
562 * Improved BSD-support for the df-plugin.
563 * Fixed syntax errors in the swap-plugin for Mac OS X.
564 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
566 * Don't disable the mysql-plugin if connecting to the database fails
567 during initialization. Instead, try again in increasing intervals.
569 2006-07-19, Version 3.10.1
570 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
571 the apcups cannot be reached, unconnected sockets will pile up and
572 eventually lead to `Too many open files' errors.
574 2006-07-09, Version 3.10.0
575 * The `disk' plugin has been ported to Darwin.
576 * The `battery' plugin should work on many Apple computers now.
577 * The `traffic' plugin can now ignore certain interfaces. Also,
578 statistics for sent/received packets and errors have been added.
579 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
580 to Anthony Gialluca for contributing this plugin and providing me
581 with a test environment :)
582 * A plugin for monitoring an NTP instance and the local clock drift
585 2006-06-25, Version 3.9.4
586 * The Solaris code in the `swap' plugin has been changed to reflect
587 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
589 * The debugging system has been fixed to work with the Sun libc.
590 * When built without librrd the variable `operating_mode' could be
591 uninitialized. Thanks to David Elliot for reporting the bug.
593 2006-06-01, Version 3.9.3
594 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
595 operating systems also profit from the changes, but I wasn't able to
597 * Changed the build system to find the netinet-includes under FreeBSD
598 and therefore successfully build the `liboping' library there.
600 2006-05-09, Version 3.9.2
601 * Applied a patch to the `liboping' library. Due to a bug in the
602 sequence checking the `ping' plugin stopped working after
603 approximately 7.6 days.
605 2006-05-09, Version 3.8.5
606 * Applied a patch to the `liboping' library. Due to a bug in the
607 sequence checking the `ping' plugin stopped working after
608 approximately 7.6 days.
610 2006-04-21, Version 3.9.1
611 * Build issues with Solaris and possible other architectures have been
613 * Problems when building the `apache'-plugin without `libcurl' have
615 * A bug in the `ping' plugin has been fixed. Sorry folks.
617 2006-04-02, Version 3.9.0
618 * A plugin to monitor the Apache webserver has been added.
619 <http://httpd.apache.org/>
620 * A plugin to collect statistics about virtual servers using VServer.
621 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
623 * A plugin for wireless LAN cards has been added. It monitors signal
624 strength, link quality and noise ratio..
625 * A plugin for Apple hardware sensors has been added.
626 * An option to compile collectd with different `step' and `heartbeat'
627 settings has been added. The size of RRAs is no longer static but
628 calculated based on the settings for `step' and `width'.
629 * The `ping' plugin can now be configured to use a certain TTL.
630 * A plugin to monitor the hardware sensors of Apple computers has been
632 * The plugins `cpu', `memory', `processes' and `traffic' have been
633 ported to Mach/Darwin (Mac OS X).
634 * The `log mode' has been contributed by Christophe Kalt. It writes
635 the data into text files rather than RRD files.
637 2006-04-09, Version 3.8.4
638 * Applied patch by Vincent Stehlé which improves the disk-name
639 resolution in the `hddtemp' plugin for Linux systems.
641 2006-04-02, Version 3.8.3
642 * Applied a patch by James Byers: The MySQL plugin was not working
643 with MySQL 5.0.2 or later.
645 2006-03-14, Version 3.8.2
646 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
647 the GNU libc, because it points to `/etc/fstab' rather than
650 2006-03-13, Version 3.8.1
651 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
652 * Fixes in the debian `postinst' and `init.d' scripts.
654 2006-03-09, Version 3.8.0
655 * The `ping' plugin no longer uses `libping' but a self written
656 library named `liboping'. With this library it's possible to ping
657 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
659 2006-02-18, Version 3.7.2
660 * A simple bug in the `battery' plugin has been fixed. It should now
661 work with ACPI based batteries as well. Thanks to Sebastian for
663 * Fixing a bug that prevented collectd to be built without librrd.
664 Thanks to Werner Heuser for reporting it.
666 2006-02-04, Version 3.7.1
667 * The new network code has been improved to build with older versions
669 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
670 to Tommie Gannert for this patch.
672 2006-01-30, Version 3.7.0
673 * The `battery' plugin has been added. It collects information about
675 * The MySQL plugin has been improved: It now writes two more RRD
676 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
677 * The `cpufreq' plugin now reads another file since the file it did
678 read so far causes much overhead in the kernel. Also, you need root
679 to read the old file, but not to read the new one.
680 * The `hddtemp' plugin can now be configured to connect to another
681 address and/or port than localhost.
682 * The `df' plugin now prefers `statvfs' over `statfs'.
683 * The network code has been rewritten. collectd now supports unicast
684 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
685 be set in the configfile.
687 2006-01-24, Version 3.6.2
688 * Due to a bug in the configfile handling collectd wouldn't start in
689 client mode. This released fixes this.
691 2006-01-20, Version 3.6.1
692 * Due to a bug in `configure.in' all modules and the binary were
693 linked against `libmysqlclient'. This issue is solved by this
696 2006-01-17, Version 3.6.0
697 * A config file has been added. This allows for loading only specific
699 * A `df' plugin has been added.
700 * A `mysql' plugin has been added.
701 * The `ping' plugin doesn't entirely give up hope when a socket error
702 occurred, but will back of and increase the intervals between tries.
704 2006-01-21, Version 3.5.2
705 * Fixed yet another bug in the signal handling.. Stupid typo..
706 * Improved the ping plugin to not give up on socket errors (backport
709 2005-12-18, Version 3.5.1
710 * The PID-file is now deleted correctly when shutting down the daemon.
711 * SIGINT and SIGTERM are now handled correctly.
713 2005-12-16, Version 3.5.0 (Revision 326)
714 * A bug in the `load' module under Solaris has been fixed.
715 * The `users' module has been contributed by Sebastian Harl. It counts
716 currently logged in users.
717 * The CPU module now works under FreeBSD without the use of
718 `libstatgrab', however SMP support is missing.
719 * The default directories for the RRD files and the PID file now
720 depend on the compile time setting of `localstatedir'.
722 2005-11-15, Version 3.4.0 (Revision 236)
723 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
724 from gentoo's bugzilla for writing the patch.
725 * The build dependency for librrd has been removed. Binaries built
726 without librrd are client-only and will multicast their value as
727 with the `-c' argument.
728 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
729 * The newly introduced `-f' switch prevents daemon initialization
730 (forking, closing standard filehandles, etc.) Thanks to Alvaro
731 Barcellos for this patch.
733 2005-11-04, Version 3.3.0 (Revision 216)
734 * New modules have been added:
735 - `serial', for monitoring traffic on the serial interfaces
736 - `nfs', for graphing NFS procedure calls
737 - `tape', traffic from/to tape devices
738 * The memory.rrd now accepts more than 4Gig of memory.
740 2005-10-26, Version 3.2.0 (Revision 200)
741 * Support for graphing the processes has been added (thanks to Lyonel
743 * If reading from hddtemp fails collectd will increase the time
744 between polls up to one day.
745 * The init.d files have been improved.
746 * Problems with the spec file have been fixed.
748 2005-10-16, Version 3.1.0 (Revision 194)
749 * Added the `setsid' syscall to the startup code.
750 * Support for hddtemp has been added (thanks to Vincent Stehlé)
752 2005-09-30, Version 3.0.0 (Revision 184)
753 * The ability to send/receive data to/from the network (think
754 multicast) has been added.
755 * Modules have been split up into shared libraries can be loaded at
756 runtime. The biggest advantage is that the core program doesn't need
757 to be linked against an external library.
758 * A patch by George Kargiotakis has been applied: It fixes the sensors
759 behaviour then more than one sensor is being queried.
761 2005-09-16, Version 2.1.0 (Revision 172)
762 * A module for swap statistics has been added.
764 2005-09-09, Version 2.0.0 (Revision 135)
765 * Filenames can no longer be configured at program startup. The only
766 options as of this version are the directory and ping hosts.
767 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
768 Soft-IRQ statistics are added to `System'.
769 * Diskstats now collect read and write bytes, not sectors.
770 * Ping statistics can now be collected for more than one host. There
771 is no default any more: If no host is given no host will be pinged.
772 * A self-written patch for libping has been applied so it builds
775 2005-09-01, Version 1.8.1 (Revision 123)
776 * Much improved configure-script: libraries and features may now be
778 * More detailed warnings/error messages when RRD update fails.
780 2005-08-29, Version 1.8.0:
781 * Support for collecting disk statistics under Solaris.
783 2005-08-25, Version 1.7.0:
784 * Support for libstatgrab[1] for load, memory usage and network
785 traffic. CPU- and disk-usage are not (yet) supported, since
786 libstatgrab returns insufficient information. I will contact the
788 * Improved the CPU-initialization code for Solaris. Apparently CPUs
789 aren't necessarily counted linear which is now handled correctly.
790 [1]: http://www.i-scream.org/libstatgrab/
792 2005-08-21, Version 1.6.0:
793 * Basic support for Solaris: System load and cpu-usage can be
794 collected under Solaris, too. Other stats will follow later.
795 * Many fixes in the autoconf-script
796 * Collection/Museum scripts have been added under contrib/museum
797 * collectd may now be started in unprivileged mode, though ping
798 statistics will not work.
800 2005-07-17, Version 1.5.1:
801 * Diskstats-RRDs now use major/minor for naming. Some systems have
802 weird strings as disk-names..
804 2005-07-17, Version 1.5:
805 * A new module, diskstats, has been added. It collects information
806 about the disks and partitions.
808 2005-07-11, Version 1.4.2:
809 * The meminfo module has been changed to work with more platforms
810 and/or kernel versions.
812 2005-07-10, Version 1.4.1: Correct traffic stats
813 * The traffic rrd-file is now created with DS-type `COUNTER' which I
814 forgot to correct when I changed that module.
816 2005-07-09, Version 1.4: More traffic stats
817 * Traffic is now collected for all interfaces that can be found
818 * Temperature-statistics are read from lm-sensors if available
820 2005-07-08, Version 1.3: CPU stats
821 * Collecting CPU statistics now
823 2004-07-12, Version 1.2: Using syslog
824 * collectd is now using the syslog facility to report errors, warnings
826 * The default directory is now /var/db/collectd
828 2004-07-10, Version 1.1: Minor changes
829 * Nothing really useful to say ;)
831 2004-07-09, Version 1.0: Initial Version
832 * The following modules are provided:
