14 * onewire plugin: The new experimental(!) onewire plugin reads values,
15 such as temperatures, from sensors connected to the computer via the
16 onewire bus.
17 * perl plugin: Improved synchronized access to internal data structures
18 and fixed a possible dead-lock.
19 * perl plugin: Added the ability to flush certain identifiers and marked
20 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
21 plugin_flush().

34 dependencies are not met. Thanks to Bruno Prémont for the patch.
35 Also, the poisoning of various string functions has been restricted
36 to debug builds.
37 * collectd: Fix a memory leak in the global value cache. With every
38 *missing* value a couple of bytes would be leaked. Another memory
39 leak in the configuration handling code has been fixed. Thanks to
40 Niraj Tolia for reporting these issues.
41 * collectd: Fix an off-by-one error in the ignorelist functionality.
42 When using regular expressions, the last character would be missing,
43 possibly matching differently from what one would expect.
44 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
45 problem.
46 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
47 Linzberger for reporting the but.

52 problems with some `libc's. Thanks to Matthias Lay for reporting the
53 bug.
55 2008-09-01, Version 4.4.3
56 * collectd: Fix a memory leak in the threshold checking code.
57 * memcached plugin: Fix a too short timeout and a related file
58 descriptor leak.

69 through 19991005.
70 * network plugin: Bugfix in the init routine: The init function
71 cleared a buffer regardless of its contents. This could lead to lost
72 values under Solaris.
73 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
74 * vserver plugin: Remove usage of the thread-unsafe `readdir'
75 function.
76 * wireless plugin: Work around incorrect noise and power values
77 returned by some broken drivers.

81 to kyrone for reporting this.
82 * collectd: Fixed min/max output in notifications generated by
83 threshold checking.
84 * collectd-nagios: Fix the protocol used to communicate with the
85 daemon.
86 * perl plugin: Fail noisily, but don't shutdown the daemon, if
87 initialization has errors. An issue with Perl 5.10 has been fixed.
88 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
89 René Rebe and Siegmund Gorr for reporting this.
91 2008-05-06, Version 4.4.0
92 * collectd: Internal code cleanups.
93 * collectd: Added support for a `Flush' command in the unixsock and
94 exec plugins. This command can be used to force a plugin (or all) to
95 flush its values to disk.
96 * collectd: Thresholds can now be configured to apply to one data
97 source only, making it possible to configure different thresholds
98 for each data source.
99 * apache, nginx plugins: Added the possibility to disable host and/or
100 peer verification.
101 * ascent plugin: The new ascent plugin reads and parses the statistics
102 page of an Ascent server.

108 sensor values via IPMI, the intelligent platform management
109 interface.
110 * iptables plugin: The iptc library that is used by the iptables
111 plugin has been added to the distribution, because it is not
112 provided by all distributions and removed from at least one.
113 * powerdns plugin: The new powerdns plugin reads statistics from an
114 authoritative or a recursing PowerDNS name server.
115 * rrdtool plugin: The size of the files generated with the default
116 configuration has been decreased.
117 * tail plugin: The new tail plugin can be used to gather statistics by
118 continuously reading from log files.

120 TeamSpeak2 server and collects statistics about the number of users
121 and number of channels.
122 * users plugin: Support for the statgrab library has been added.
123 * vmem plugin: The new vmem plugin collects very detailed statistics
124 about the virtual memory subsystem of Linux.
126 2008-08-30, Version 4.3.4
127 * Build system: Improved detection of and linking with the statgrab
128 library.
129 * collectd: Portability fixes, especially to determine endianess more
130 reliable.
131 * Various plugins: Fix format strings.

146 they are in non-standard paths.
147 * build system: Portability fixes: Automatically define "_REENTRANT"
148 if the libc expects it.
149 * collectd: Error and warning messages have been improved.
150 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
151 using them.
152 * apache plugin: Allocate new memory when reading a webpage instead of
153 using a buffer of static size.
154 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
155 the program.
156 * hddtemp plugin: Error and warning messages have been improved.
157 * sensors plugin: Fix sensor collection for some chip types.
159 2008-03-29, Version 4.3.2

170 * network plugin:
171 + Use `memcpy' when constructing/parsing a package to avoid
172 alignment problems on weird architectures, such as Sparc.
173 + Translate doubles to/from the x86 byte representation to ensure
174 cross-platform compatibility.
175 * ping plugin: Correct the handling of the `TTL' setting.
176 * swap plugin: Reapply a patch for Solaris.
177 * tcpconns plugin: Portability improvements.
179 2008-02-18, Version 4.3.0
180 * collectd: Notifications have been added to the daemon. Notifications
181 are status messages that may be associated with a data instance.
182 * collectd: Threshold checking has been added to the daemon. This
183 means that you can configure threshold values for each data
184 instance. If this threshold is exceeded a notification will be
185 created.
186 * collectd: The new `FQDNLookup' option tells the daemon to use the
187 full qualified domain name as the hostname, not just the host part
188 es returned by `gethostname(2)'.
189 * collectd: Support for more than one `TypesDB' file has been added.
190 This is useful when one such file is included in a package but one
191 wants to add custom type definitions.
192 * collectd: The `Include' config option has been expanded to handle
193 entire directories and shell wildcards.
194 * collectdmon: The new `collectdmon' binary detects when collectd
195 terminates and automatically restarts it again.
196 * csv plugin: The CSV plugin is now able to store counter values as a
197 rate, using the `StoreRates' configuration option.
198 * exec plugin: Handling of notifications has been added and the
199 ability to pass arguments to the executed programs has been added.
200 * hddtemp plugin: The new `TranslateDevicename' option lets you
201 disable the translation from device names to major-minor-numbers.
202 * logfile plugin: Handling of notifications has been added.
203 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
204 domain name lookups in this plugin.
205 * perl plugin: Many internal changes added support for handling multiple
206 threads making the plugin reasonably usable inside collectd. The API has
207 been extended to support notifications and export global variables to
208 Perl plugins; callbacks now have to be identified by name rather than a
209 pointer to a subroutine. The plugin is no longer experimental.
210 * uuid plugin: The new UUID plugin sets the hostname to an unique
211 identifier for this host. This is meant for setups where each client
212 may migrate to another physical host, possibly going through one or
213 more name changes in the process. Thanks to Richard Jones from
214 Red Hat's Emerging Technology group for this plugin.
215 * libvirt: The new libvirt plugin uses the `libvirt' library to query
216 CPU, disk and network statistics about guest systems on the same
217 physical server. Thanks to Richard Jones from Red Hat's Emerging
218 Technology group for this plugin.
220 2008-04-22, Version 4.2.7
221 * build system: Improved detection of several libraries, especially if
222 they are in non-standard paths.
223 * build system: Portability fixes: Automatically define "_REENTRANT"
224 if the libc expects it.
225 * collectd: Error and warning messages have been improved.
226 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
227 using them.
228 * apache plugin: Allocate new memory when reading a webpage instead of
229 using a buffer of static size.
230 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
231 the program.
232 * hddtemp plugin: Error and warning messages have been improved.
233 * sensors plugin: Fix sensor collection for some chip types.
235 2008-03-29, Version 4.2.6
236 * collectd: Improved error messages when parsing the configuration.
237 * sensors plugin: Fix temperature collection with libsensors4.
238 * unixsock plugin: Fix mixed input and output operation on streams.
239 * wireless plugin: Fix reading noise value.
241 2008-03-04, Version 4.2.5
242 * apache plugin: Improved initialization and error messages.
243 * exec plugin: Set supplementary group IDs.
244 * network plugin:
245 + Create separate threads for reading from the socket and parsing
246 and dispatching incoming packets. Versions prior to this may have
247 problems in high-load situations, where the socket receive buffers
248 overflows, resulting in gaps in the data.
249 + Use `memcpy' when constructing/parsing a package to avoid
250 alignment problems on weird architectures, such as Sparc.
251 + Translate doubles to/from the x86 byte representation to ensure
252 cross-platform compatibility.
253 * ping plugin: Correct the handling of the `TTL' setting.
254 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
255 * swap plugin: Reapply a patch for Solaris.
256 * tcpconns plugin: Portability improvements.
258 2008-01-21, Version 4.2.4
259 * unixsock plugin: A bug in the unixsock plugin caused it not to set
260 the permission on the socket as documented in the manpage. Thanks to
261 Evgeny Chukreev for fixing this issue.
262 * collectd: The documentation has been improved.
264 2007-12-28, Version 4.2.3
265 * sensors plugin: Updated the plugin to build and work with version 3
266 of the libsensors library.
268 2007-12-15, Version 4.2.2
269 * nginx plugin: Incorrect comparison of strings lead to a segfault
270 when using the plugin. Thanks to Saulius Grigaliunas for fixing
271 this.
272 * logfile plugin: The config option `Timestamp' was handled
273 incorrectly and basically always active. Thanks to Luke Heberling
274 for fixing this.
276 2007-11-08, Version 4.2.1
277 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
278 enabled on the host.
279 * snmp plugin: Fix a memory leak.
281 2007-10-27, Version 4.2.0
282 * collectd: The new config option `Include' lets you include other
283 configfiles and thus split up your config into smaller parts. This
284 may be especially interesting for the snmp plugin to keep the data
285 definitions separate from the host definitions.
286 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
287 (number of connections, octets and packets for each service and
288 destination). Thanks to Sebastian Harl for this plugin.
289 * memcached plugin: The new `memcached' plugin connects to a memcached
290 daemon process and collects statistics of this distributed caching
291 system. Thanks to Antony Dovgal for contributing this plugin.
292 * nginx plugin: The new `nginx' plugin reads the status page of an
293 nginx daemon and saves the handled connections and requests.
294 * perl plugin: Many changes, including the added `EnableDebugger'
295 config option which lets you debug your Perl plugins more easily.
296 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
297 be more thread-safe otherwise by locking calls to the library.
298 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
299 correct the values returned by SNMP-agents. If a <data> block is
300 defined as `table' the instance is now optional. The sequence number
301 is used as the type-instance in this case. The new `InstancePrefix'
302 option allows to add arbitrary prefixes to the type-instance.
303 * tcpconns plugin: The new `tcpconns' plugin collects the number of
304 certain TCP connections and what state they're in. This can be used
305 to see how many connections your FTP server has to handle or how
306 many outgoing connections your mailserver has open.
308 2008-01-11, Version 4.1.6
309 * unixsock plugin: A bug in the unixsock plugin caused it not to set
310 the permission on the socket as documented in the manpage. Thanks to
311 Evgeny Chukreev for fixing this issue.
312 * collectd: The documentation has been improved.
314 2007-12-27, Version 4.1.5
315 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
316 memory situations.

318 of the libsensors library.
320 2007-11-08, Version 4.1.4
321 * Build system: Improve detection of the rrd library, especially if
322 it's in a non-standard location.
323 * Build system: A bug when parsing the argument for
324 `--with-libnetsnmp' has been fixed.
325 * collectd: Implement `strerror_r' if the libc doesn't provide it.
326 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
327 a deadlock or delay when shutting down the daemon.
328 * snmp plugin: Fix a memory leak.
330 2007-10-24, Version 4.1.3
331 * collectd: A build issue under Solaris has been resolved by renaming
332 data types.
333 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
334 be more thread-safe otherwise by locking calls to the library.
336 2007-09-28, Version 4.1.2
337 * apcups plugin: Fix reporting of the `load percent' data.
338 * wireless plugin: Correct the handling of cards returning signal and
339 noise quality as percentage.
340 * perl plugin: Fix a possible buffer overflow in get_module_name().
341 * build system: Further improve the detection of libraries.
342 * netlink plugin: Build issues under some older versions of the Linux
343 includes (i. e. Debian Sarge) have been fixed.
344 * snmp plugin: Fix a potential segfault when a host times out. Add
345 support for the `timeticks' type.
347 2007-09-12, Version 4.1.1
348 * Build system: The detection of `libnetlink' has been improved.
349 * collectd: The documentation has been fixed in numerous places.
350 * exec plugin: Setting the group under which to run a program has been
351 fixed.
352 * collectd: The `sstrerror' function was improved to work correctly
353 with the broken GNU version of `strerror_r'.
354 * collectd: Write an error message to STDERR when loading of a plugin
355 fails.
356 * apcups plugin: Fix the `types' used to submit the values: They still
357 has an `apcups_' prefix which doesn't work anymore.
358 * rrdtool plugin: Create new RRD-files with the `begin' time set to
359 whatever the client thinks is `now'..
361 2007-09-01, Version 4.1.0
362 * Build system: The build system has been changed to automatically
363 disable all plugins, which are missing dependencies. The dependency
364 checking has been removed from the plugins themselves to remove
365 redundancy.
366 * Flexible interval: The interval of collected data is now sent along
367 with the data itself over the network, so that the interval-settings
368 of server and clients no longer needs to match.
369 * netlink plugin: The new `netlink' plugin connects to the Linux
370 kernel using a netlink socket and uses it to query information about
371 interfaces, qdiscs and classes.
372 * rrdtool plugin: The cache is now dumped to disk in an extra thread
373 to not block data collection.
374 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
375 network devices, such as switches, routers, thermometers, rack
376 monitoring servers, etc. The collectd-snmp(5) manpage documents this
377 plugin.
378 * unixsock plugin: Added the `LISTVAL' command.
379 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
380 of music played with xmms.
382 2007-09-28, Version 4.0.9

384 * wireless plugin: Correct the handling of cards returning signal and
385 noise quality as percentage.
386 * perl plugin: Fix a possible buffer overflow in get_module_name().
388 2007-09-12, Version 4.0.8
389 * collectd: The `sstrerror' function was improved to work correctly
390 with the broken GNU version of `strerror_r'.
391 * collectd: Write an error message to STDERR when loading of a plugin
392 fails.
393 * apcups plugin: Fix the `types' used to submit the values: They still
394 has an `apcups_' prefix which doesn't work anymore.
395 * rrdtool plugin: Create new RRD-files with the `begin' time set to
396 whatever the client thinks is `now'..
398 2007-08-26, Version 4.0.7
399 * documentation: Some typos have been fixed and some information has
400 been improved.
401 * build system: Many fixes for detecting libraries in unusual places,
402 such as on RedHat systems. The affected libraries are `libcurl',
403 `libmysql', and `libupsclient'.
404 * network plugin: Allow the `Port' option to be specified as a number
405 (i. e. without quotes).
406 * nut plugin: A fix allows linking the nut plugin against
407 libupsclient, version >= 2.2.0.
408 * processes plugin: Fix a potential segmentation fault.
410 2007-07-30, Version 4.0.6
411 * sensors plugin: Fix the ignorelist functionality: Only the `type
412 instance' was used to match against the list, but the documentation
413 told otherwise. This release fixes the code, so it complies with the
414 documentation.
415 * syslog plugin: Call `openlog' right when the plugin is loaded, so
416 configuration messages will end up in the logging facility.
417 * conrtib/fedora: The contributed specfile for Fedora has been
418 updated.
420 2007-07-05, Version 4.0.5
421 * Portability: More fixes for OpenBSD have been included.
423 2007-06-24, Version 4.0.4
424 * cpu plugin: Fixed the Solaris code.
425 * dns plugin: Fixed a build issue for OpenBSD.
426 * interface plugin: Fixed the Solaris code.
427 * load plugin: Fixed the alternative `/proc' Linux code.
428 * memory plugin: Fixed the Solaris code.
429 * oconfig: Don't require `-lfl' anymore.
431 2007-06-19, Version 4.0.3
432 * cpu plugin: Fix the Darwin / Mac OS X code.
433 * ping plugin: Use the return value of `getpid', not its address.
434 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
435 initialized correctly.
436 * configure: Added `--with-nan-emulation' to aid cross compilation.
438 2007-06-12, Version 4.0.2
439 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
440 they're given in numerically form.
442 2007-06-07, Version 4.0.1
443 * iptables plugin: A bug in the configuration routine has been fixed.
444 Setting a comment in the configfile will no longer cause a
445 segmentation fault.
447 2007-06-03, Version 4.0.0
448 * collectd: The plugin-infrastructure has been changed to allow for
449 more types of plugins, namely `write' and `log' plugins.
450 * collectd: The read-function has been changed to read many plugins in
451 parallel, using threads. Thus, plugins generally need to use
452 thread-safe functions from now on.
453 * collectd: The '-t' command line options allows to perform syntax tests
454 of the configuration file and exit immediately.
455 * csv plugin: The new `csv' plugin handles output to `comma separated
456 values'-files.
457 * rrdtool plugin: The new `rrdtool' plugin handles output to
458 RRD-files. Data can be cached to combine multiple updates into one
459 write to increase IO-performance.
460 * network plugin: The new `network' plugin handles IO via the network.
461 It implements a different, much more extensible protocol which can
462 combine many values in one packet, decreasing the number of UDP-
463 packets being sent. It can read from and send to the network and
464 with the appropriate configuration even forward packets to other
465 networks.
466 * unixsock plugin: The new `unixsock' plugin provides an interface to
467 communicate with the daemon while it is running. Right now the
468 commands `GETVAL' and `PUTVAL' are implemented, but more are to
469 come.
470 * perl plugin: The new `perl' plugin allows you to write extensions
471 for collectd in the scripting-language Perl.
472 * logfile plugin: The new `logfile' plugin writes logmessages to files
473 or STDOUT or STDERR.
474 * syslog plugin: The new `syslog' plugin sends logmessages to the
475 system's syslog daemon.
476 * entropy plugin: The new `entropy' plugin collects the amount of
477 entropy currently being available to the system.
478 * exec plugin: The new `exec' plugin forks child processes and reads
479 back values provided by the forked processes.

481 iptables rules. Thanks to Sjoerd van der Berg for contributing this
482 plugin.
483 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
484 to Peter Holik for contributing this plugin.
485 * nut plugin: The new `nut' plugin connects the upsd of the `network
486 ups tools' and reads information about the connected UPS.
487 * apache plugin: Support for lighttpd's `BusyServers' (aka.
488 connections) field was added by Florent Monbillard.
489 * collectd-nagios: The new `collectd-nagios' binary queries values
490 from collectd, parses them and exits according to Nagios-standards.
491 * manpages: The manpages have been improved a lot.
493 2007-09-28, Version 3.11.7
494 * wireless plugin: Correct the handling of cards returning signal and
495 noise quality as percentage.
497 2007-08-31, Version 3.11.6
498 * processes plugin: Fix a potential segmentation fault.
500 2007-05-29, Version 3.11.5
501 * configure: Added `AC_SYS_LARGEFILE' for LFS.
502 * ntpd plugin: Fix a potential buffer overflow.
503 * processes plugin: Fix a bug when run under Linux 2.4. All processes
504 were accounted as `zombies'.
506 2007-04-10, Version 3.11.4
507 * dns plugin: Change the order of includes to make the plugin compile
508 under FreeBSD.
510 2007-03-30, Version 3.11.3
511 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
512 of the unused `COLLECT_KSTAT'.
514 2007-02-11, Version 3.11.2
515 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
516 NULL-pointer may have been passed to `printf' which causes a
517 segfault with some libcs.
519 2007-02-10, Version 3.11.1
520 * df plugin: Some wrong defines have been fixed so the plugin works
521 under Solaris again.
522 * dns plugin: The usage of a struct has been fixed to work with
523 non-GNU libcs.
524 * processes plugin: Some missing defines have been added so the plugin
525 compiles cleanly under FreeBSD and presumably other UNIXes.
527 2006-12-22, Version 3.11.0
528 * collectd: The new command line option `-P' makes it easier for
529 distributors to change the location of PID-files.
530 * collectd: The daemon shuts down faster now which makes it easier to
531 write init.d-scripts for it.
532 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
533 caused problems every now and then.
534 * df plugin: New config options allow to ignore certain mountpoints,
535 filesystem types or devices.
536 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
537 and interprets it. It collects traffic as well as qtype, opcode and
538 rcode counts.
539 * email plugin: Sebastian Harl has contributed this plugin which
540 counts received mails in categories (e. g. ham, spam, virus), spam
541 score (as given by SpamAssassin) and check types.
542 * mbmon plugin: Flavio Stanchina has contributed this plugin which
543 uses `mbmon' to gather information from sensors on the motherboard.
544 * processes plugin: Collect detailed statistics for configured
545 processes, that's process and thread count, CPU usage, resident
546 segment size and pagefaults.
547 * multimeter plugin: Peter Holik contributed a new plugin which
548 queries multimeters.
549 * sensors plugin: Lubos Stanek has put much effort into improving this
550 plugin, including `extended naming', collection of voltage values
551 and the possibility to ignore certain values.
553 2006-12-21, Version 3.10.4
554 * Max Kellermann has identified a bug in the server routine: When
555 opening a socket fails the daemon will (re)try opening the socket in
556 an endless loop, ultimately leading to a `EMFILE' error.
558 2006-11-04, Version 3.10.3
559 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
560 ntpd's reply was sent in more than one packet, the buffer size was
561 calculated incorrectly, resulting in the reading of uninitialized or
562 freed memory.
564 2006-11-01, Version 3.10.2
565 * The sample config file has been improved.
566 * Errors in the manpages have been corrected.
567 * The ping-plugin now adds hosts during initialization, not during
568 startup. This speeds up startup when no network connectivity is
569 available. Also, the hosts are being added later when the network is
570 available.
571 * Improved BSD-support for the df-plugin.
572 * Fixed syntax errors in the swap-plugin for Mac OS X.
573 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
574 plugin.
575 * Don't disable the mysql-plugin if connecting to the database fails
576 during initialization. Instead, try again in increasing intervals.
578 2006-07-19, Version 3.10.1
579 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
580 the apcups cannot be reached, unconnected sockets will pile up and
581 eventually lead to `Too many open files' errors.
583 2006-07-09, Version 3.10.0
584 * The `disk' plugin has been ported to Darwin.
585 * The `battery' plugin should work on many Apple computers now.
586 * The `traffic' plugin can now ignore certain interfaces. Also,
587 statistics for sent/received packets and errors have been added.
588 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
589 to Anthony Gialluca for contributing this plugin and providing me
590 with a test environment :)
591 * A plugin for monitoring an NTP instance and the local clock drift
592 has been added.
594 2006-06-25, Version 3.9.4
595 * The Solaris code in the `swap' plugin has been changed to reflect
596 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
597 working this out.
598 * The debugging system has been fixed to work with the Sun libc.
599 * When built without librrd the variable `operating_mode' could be
600 uninitialized. Thanks to David Elliot for reporting the bug.
602 2006-06-01, Version 3.9.3
603 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
604 operating systems also profit from the changes, but I wasn't able to
605 check that.
606 * Changed the build system to find the netinet-includes under FreeBSD
607 and therefore successfully build the `liboping' library there.
609 2006-05-09, Version 3.9.2
610 * Applied a patch to the `liboping' library. Due to a bug in the
611 sequence checking the `ping' plugin stopped working after
612 approximately 7.6 days.
614 2006-05-09, Version 3.8.5
615 * Applied a patch to the `liboping' library. Due to a bug in the
616 sequence checking the `ping' plugin stopped working after
617 approximately 7.6 days.
619 2006-04-21, Version 3.9.1
620 * Build issues with Solaris and possible other architectures have been
621 resolved.
622 * Problems when building the `apache'-plugin without `libcurl' have
623 been resolved.
624 * A bug in the `ping' plugin has been fixed. Sorry folks.
626 2006-04-02, Version 3.9.0
627 * A plugin to monitor the Apache webserver has been added.
628 <http://httpd.apache.org/>
629 * A plugin to collect statistics about virtual servers using VServer.
630 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
631 this plugin :)
632 * A plugin for wireless LAN cards has been added. It monitors signal
633 strength, link quality and noise ratio..
634 * A plugin for Apple hardware sensors has been added.
635 * An option to compile collectd with different `step' and `heartbeat'
636 settings has been added. The size of RRAs is no longer static but
637 calculated based on the settings for `step' and `width'.
638 * The `ping' plugin can now be configured to use a certain TTL.
639 * A plugin to monitor the hardware sensors of Apple computers has been
640 added.
641 * The plugins `cpu', `memory', `processes' and `traffic' have been
642 ported to Mach/Darwin (Mac OS X).
643 * The `log mode' has been contributed by Christophe Kalt. It writes
644 the data into text files rather than RRD files.
646 2006-04-09, Version 3.8.4
647 * Applied patch by Vincent Stehlé which improves the disk-name
648 resolution in the `hddtemp' plugin for Linux systems.
650 2006-04-02, Version 3.8.3
651 * Applied a patch by James Byers: The MySQL plugin was not working
652 with MySQL 5.0.2 or later.
654 2006-03-14, Version 3.8.2
655 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
656 the GNU libc, because it points to `/etc/fstab' rather than
657 `/etc/mtab'.
659 2006-03-13, Version 3.8.1
660 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
661 * Fixes in the debian `postinst' and `init.d' scripts.
663 2006-03-09, Version 3.8.0
664 * The `ping' plugin no longer uses `libping' but a self written
665 library named `liboping'. With this library it's possible to ping
666 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
668 2006-02-18, Version 3.7.2
669 * A simple bug in the `battery' plugin has been fixed. It should now
670 work with ACPI based batteries as well. Thanks to Sebastian for
671 fixing this.
672 * Fixing a bug that prevented collectd to be built without librrd.
673 Thanks to Werner Heuser for reporting it.
675 2006-02-04, Version 3.7.1
676 * The new network code has been improved to build with older versions
677 of glibc.
678 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
679 to Tommie Gannert for this patch.
681 2006-01-30, Version 3.7.0
682 * The `battery' plugin has been added. It collects information about
683 laptop batteries..
684 * The MySQL plugin has been improved: It now writes two more RRD
685 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
686 * The `cpufreq' plugin now reads another file since the file it did
687 read so far causes much overhead in the kernel. Also, you need root
688 to read the old file, but not to read the new one.
689 * The `hddtemp' plugin can now be configured to connect to another
690 address and/or port than localhost.
691 * The `df' plugin now prefers `statvfs' over `statfs'.
692 * The network code has been rewritten. collectd now supports unicast
693 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
694 be set in the configfile.
696 2006-01-24, Version 3.6.2
697 * Due to a bug in the configfile handling collectd wouldn't start in
698 client mode. This released fixes this.
700 2006-01-20, Version 3.6.1
701 * Due to a bug in `configure.in' all modules and the binary were
702 linked against `libmysqlclient'. This issue is solved by this
703 release.
705 2006-01-17, Version 3.6.0
706 * A config file has been added. This allows for loading only specific
707 plugins.
708 * A `df' plugin has been added.
709 * A `mysql' plugin has been added.
710 * The `ping' plugin doesn't entirely give up hope when a socket error
711 occurred, but will back of and increase the intervals between tries.
713 2006-01-21, Version 3.5.2
714 * Fixed yet another bug in the signal handling.. Stupid typo..
715 * Improved the ping plugin to not give up on socket errors (backport
716 from 3.6.0).
718 2005-12-18, Version 3.5.1
719 * The PID-file is now deleted correctly when shutting down the daemon.
720 * SIGINT and SIGTERM are now handled correctly.
722 2005-12-16, Version 3.5.0 (Revision 326)
723 * A bug in the `load' module under Solaris has been fixed.
724 * The `users' module has been contributed by Sebastian Harl. It counts
725 currently logged in users.
726 * The CPU module now works under FreeBSD without the use of
727 `libstatgrab', however SMP support is missing.
728 * The default directories for the RRD files and the PID file now
729 depend on the compile time setting of `localstatedir'.
731 2005-11-15, Version 3.4.0 (Revision 236)
732 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
733 from gentoo's bugzilla for writing the patch.
734 * The build dependency for librrd has been removed. Binaries built
735 without librrd are client-only and will multicast their value as
736 with the `-c' argument.
737 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
738 * The newly introduced `-f' switch prevents daemon initialization
739 (forking, closing standard filehandles, etc.) Thanks to Alvaro
740 Barcellos for this patch.
742 2005-11-04, Version 3.3.0 (Revision 216)
743 * New modules have been added:
744 - `serial', for monitoring traffic on the serial interfaces
745 - `nfs', for graphing NFS procedure calls
746 - `tape', traffic from/to tape devices
747 * The memory.rrd now accepts more than 4Gig of memory.
749 2005-10-26, Version 3.2.0 (Revision 200)
750 * Support for graphing the processes has been added (thanks to Lyonel
751 Vincent)
752 * If reading from hddtemp fails collectd will increase the time
753 between polls up to one day.
754 * The init.d files have been improved.
755 * Problems with the spec file have been fixed.
757 2005-10-16, Version 3.1.0 (Revision 194)
758 * Added the `setsid' syscall to the startup code.
759 * Support for hddtemp has been added (thanks to Vincent Stehlé)
761 2005-09-30, Version 3.0.0 (Revision 184)
762 * The ability to send/receive data to/from the network (think
763 multicast) has been added.
764 * Modules have been split up into shared libraries can be loaded at
765 runtime. The biggest advantage is that the core program doesn't need
766 to be linked against an external library.
767 * A patch by George Kargiotakis has been applied: It fixes the sensors
768 behaviour then more than one sensor is being queried.
770 2005-09-16, Version 2.1.0 (Revision 172)
771 * A module for swap statistics has been added.
773 2005-09-09, Version 2.0.0 (Revision 135)
774 * Filenames can no longer be configured at program startup. The only
775 options as of this version are the directory and ping hosts.
776 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
777 Soft-IRQ statistics are added to `System'.
778 * Diskstats now collect read and write bytes, not sectors.
779 * Ping statistics can now be collected for more than one host. There
780 is no default any more: If no host is given no host will be pinged.
781 * A self-written patch for libping has been applied so it builds
782 cleanly.
784 2005-09-01, Version 1.8.1 (Revision 123)
785 * Much improved configure-script: libraries and features may now be
786 disabled.
787 * More detailed warnings/error messages when RRD update fails.
789 2005-08-29, Version 1.8.0:
790 * Support for collecting disk statistics under Solaris.
792 2005-08-25, Version 1.7.0:
793 * Support for libstatgrab[1] for load, memory usage and network
794 traffic. CPU- and disk-usage are not (yet) supported, since
795 libstatgrab returns insufficient information. I will contact the
796 authors.
797 * Improved the CPU-initialization code for Solaris. Apparently CPUs
798 aren't necessarily counted linear which is now handled correctly.
799 [1]: http://www.i-scream.org/libstatgrab/
801 2005-08-21, Version 1.6.0:
802 * Basic support for Solaris: System load and cpu-usage can be
803 collected under Solaris, too. Other stats will follow later.
804 * Many fixes in the autoconf-script
805 * Collection/Museum scripts have been added under contrib/museum
806 * collectd may now be started in unprivileged mode, though ping
807 statistics will not work.
809 2005-07-17, Version 1.5.1:
810 * Diskstats-RRDs now use major/minor for naming. Some systems have
811 weird strings as disk-names..
813 2005-07-17, Version 1.5:
814 * A new module, diskstats, has been added. It collects information
815 about the disks and partitions.
817 2005-07-11, Version 1.4.2:
818 * The meminfo module has been changed to work with more platforms
819 and/or kernel versions.
821 2005-07-10, Version 1.4.1: Correct traffic stats
822 * The traffic rrd-file is now created with DS-type `COUNTER' which I
823 forgot to correct when I changed that module.
825 2005-07-09, Version 1.4: More traffic stats
826 * Traffic is now collected for all interfaces that can be found
827 * Temperature-statistics are read from lm-sensors if available
829 2005-07-08, Version 1.3: CPU stats
830 * Collecting CPU statistics now
832 2004-07-12, Version 1.2: Using syslog
833 * collectd is now using the syslog facility to report errors, warnings
834 and the like..
835 * The default directory is now /var/db/collectd
837 2004-07-10, Version 1.1: Minor changes
838 * Nothing really useful to say ;)
840 2004-07-09, Version 1.0: Initial Version
841 * The following modules are provided:
842 * Load average
843 * Ping time
844 * Traffic
845 * Memory info
