10 * collectd: Try even harder to determine the endianess of the
11 architecture collectd is being built on.
12 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
14 * dns plugin: Fix compilation errors with BIND versions 19991001
16 * network plugin: Bugfix in the init routine: The init function
17 cleared a buffer regardless of its contents. This could lead to lost
19 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
20 * vserver plugin: Remove usage of the thread-unsafe `readdir'
22 * wireless plugin: Work around incorrect noise and power values
23 returned by some broken drivers.
25 2008-06-03, Version 4.4.1
26 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
27 to kyrone for reporting this.
28 * collectd: Fixed min/max output in notifications generated by
30 * collectd-nagios: Fix the protocol used to communicate with the
32 * perl plugin: Fail noisily, but don't shutdown the daemon, if
33 initialization has errors. An issue with Perl 5.10 has been fixed.
34 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
35 René Rebe and Siegmund Gorr for reporting this.

38 * collectd: Internal code cleanups.
39 * collectd: Added support for a `Flush' command in the unixsock and
40 exec plugins. This command can be used to force a plugin (or all) to
41 flush its values to disk.
42 * collectd: Thresholds can now be configured to apply to one data
43 source only, making it possible to configure different thresholds
45 * apache, nginx plugins: Added the possibility to disable host and/or
47 * ascent plugin: The new ascent plugin reads and parses the statistics
48 page of an Ascent server.

53 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
54 sensor values via IPMI, the intelligent platform management
56 * iptables plugin: The iptc library that is used by the iptables
57 plugin has been added to the distribution, because it is not
58 provided by all distributions and removed from at least one.
59 * powerdns plugin: The new powerdns plugin reads statistics from an
60 authoritative or a recursing PowerDNS name server.
61 * rrdtool plugin: The size of the files generated with the default
62 configuration has been decreased.
63 * tail plugin: The new tail plugin can be used to gather statistics by
64 continuously reading from log files.
65 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
66 TeamSpeak2 server and collects statistics about the number of users
67 and number of channels.
68 * users plugin: Support for the statgrab library has been added.
69 * vmem plugin: The new vmem plugin collects very detailed statistics
70 about the virtual memory subsystem of Linux.

90 2008-04-22, Version 4.3.3
91 * build system: Improved detection of several libraries, especially if
92 they are in non-standard paths.
93 * build system: Portability fixes: Automatically define "_REENTRANT"
94 if the libc expects it.
95 * collectd: Error and warning messages have been improved.
96 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
98 * apache plugin: Allocate new memory when reading a webpage instead of
99 using a buffer of static size.
100 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
102 * hddtemp plugin: Error and warning messages have been improved.
103 * sensors plugin: Fix sensor collection for some chip types.
105 2008-03-29, Version 4.3.2
106 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
107 `Persist' threshold options.
108 * collectd: Fix handling of missing values in the global value cache.
109 * collectd: Improved error messages when parsing the configuration.

114 2008-03-05, Version 4.3.1
115 * exec plugin: Set supplementary group IDs.
117 + Use `memcpy' when constructing/parsing a package to avoid
118 alignment problems on weird architectures, such as Sparc.
119 + Translate doubles to/from the x86 byte representation to ensure
120 cross-platform compatibility.
121 * ping plugin: Correct the handling of the `TTL' setting.
122 * swap plugin: Reapply a patch for Solaris.
123 * tcpconns plugin: Portability improvements.
125 2008-02-18, Version 4.3.0
126 * collectd: Notifications have been added to the daemon. Notifications
127 are status messages that may be associated with a data instance.
128 * collectd: Threshold checking has been added to the daemon. This
129 means that you can configure threshold values for each data
130 instance. If this threshold is exceeded a notification will be
132 * collectd: The new `FQDNLookup' option tells the daemon to use the
133 full qualified domain name as the hostname, not just the host part
134 es returned by `gethostname(2)'.
135 * collectd: Support for more than one `TypesDB' file has been added.
136 This is useful when one such file is included in a package but one
137 wants to add custom type definitions.
138 * collectd: The `Include' config option has been expanded to handle
139 entire directories and shell wildcards.
140 * collectdmon: The new `collectdmon' binary detects when collectd

142 * csv plugin: The CSV plugin is now able to store counter values as a
143 rate, using the `StoreRates' configuration option.
144 * exec plugin: Handling of notifications has been added and the
145 ability to pass arguments to the executed programs has been added.
146 * hddtemp plugin: The new `TranslateDevicename' option lets you
147 disable the translation from device names to major-minor-numbers.
148 * logfile plugin: Handling of notifications has been added.
149 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
150 domain name lookups in this plugin.
151 * perl plugin: Many internal changes added support for handling multiple
152 threads making the plugin reasonably usable inside collectd. The API has
153 been extended to support notifications and export global variables to
154 Perl plugins; callbacks now have to be identified by name rather than a
155 pointer to a subroutine. The plugin is no longer experimental.
156 * uuid plugin: The new UUID plugin sets the hostname to an unique
157 identifier for this host. This is meant for setups where each client
158 may migrate to another physical host, possibly going through one or
159 more name changes in the process. Thanks to Richard Jones from
160 Red Hat's Emerging Technology group for this plugin.
161 * libvirt: The new libvirt plugin uses the `libvirt' library to query
162 CPU, disk and network statistics about guest systems on the same
163 physical server. Thanks to Richard Jones from Red Hat's Emerging
164 Technology group for this plugin.
166 2008-04-22, Version 4.2.7
167 * build system: Improved detection of several libraries, especially if
168 they are in non-standard paths.

170 if the libc expects it.
171 * collectd: Error and warning messages have been improved.
172 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
174 * apache plugin: Allocate new memory when reading a webpage instead of
175 using a buffer of static size.
176 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
178 * hddtemp plugin: Error and warning messages have been improved.
179 * sensors plugin: Fix sensor collection for some chip types.
181 2008-03-29, Version 4.2.6
182 * collectd: Improved error messages when parsing the configuration.
183 * sensors plugin: Fix temperature collection with libsensors4.
184 * unixsock plugin: Fix mixed input and output operation on streams.
185 * wireless plugin: Fix reading noise value.
187 2008-03-04, Version 4.2.5
188 * apache plugin: Improved initialization and error messages.
189 * exec plugin: Set supplementary group IDs.
191 + Create separate threads for reading from the socket and parsing
192 and dispatching incoming packets. Versions prior to this may have
193 problems in high-load situations, where the socket receive buffers
194 overflows, resulting in gaps in the data.
195 + Use `memcpy' when constructing/parsing a package to avoid
196 alignment problems on weird architectures, such as Sparc.
197 + Translate doubles to/from the x86 byte representation to ensure
198 cross-platform compatibility.
199 * ping plugin: Correct the handling of the `TTL' setting.
200 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
201 * swap plugin: Reapply a patch for Solaris.
202 * tcpconns plugin: Portability improvements.
204 2008-01-21, Version 4.2.4
205 * unixsock plugin: A bug in the unixsock plugin caused it not to set
206 the permission on the socket as documented in the manpage. Thanks to
207 Evgeny Chukreev for fixing this issue.
208 * collectd: The documentation has been improved.
210 2007-12-28, Version 4.2.3
211 * sensors plugin: Updated the plugin to build and work with version 3
212 of the libsensors library.
214 2007-12-15, Version 4.2.2
215 * nginx plugin: Incorrect comparison of strings lead to a segfault
216 when using the plugin. Thanks to Saulius Grigaliunas for fixing
218 * logfile plugin: The config option `Timestamp' was handled
219 incorrectly and basically always active. Thanks to Luke Heberling
222 2007-11-08, Version 4.2.1
223 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
225 * snmp plugin: Fix a memory leak.
227 2007-10-27, Version 4.2.0
228 * collectd: The new config option `Include' lets you include other
229 configfiles and thus split up your config into smaller parts. This
230 may be especially interesting for the snmp plugin to keep the data
231 definitions separate from the host definitions.
232 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
233 (number of connections, octets and packets for each service and
234 destination). Thanks to Sebastian Harl for this plugin.
235 * memcached plugin: The new `memcached' plugin connects to a memcached
236 daemon process and collects statistics of this distributed caching
237 system. Thanks to Antony Dovgal for contributing this plugin.
238 * nginx plugin: The new `nginx' plugin reads the status page of an
239 nginx daemon and saves the handled connections and requests.
240 * perl plugin: Many changes, including the added `EnableDebugger'
241 config option which lets you debug your Perl plugins more easily.
242 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
243 be more thread-safe otherwise by locking calls to the library.
244 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
245 correct the values returned by SNMP-agents. If a <data> block is
246 defined as `table' the instance is now optional. The sequence number
247 is used as the type-instance in this case. The new `InstancePrefix'
248 option allows to add arbitrary prefixes to the type-instance.
249 * tcpconns plugin: The new `tcpconns' plugin collects the number of
250 certain TCP connections and what state they're in. This can be used
251 to see how many connections your FTP server has to handle or how
252 many outgoing connections your mailserver has open.
254 2008-01-11, Version 4.1.6
255 * unixsock plugin: A bug in the unixsock plugin caused it not to set
256 the permission on the socket as documented in the manpage. Thanks to
257 Evgeny Chukreev for fixing this issue.
258 * collectd: The documentation has been improved.
260 2007-12-27, Version 4.1.5

264 of the libsensors library.
266 2007-11-08, Version 4.1.4
267 * Build system: Improve detection of the rrd library, especially if
268 it's in a non-standard location.
269 * Build system: A bug when parsing the argument for
270 `--with-libnetsnmp' has been fixed.
271 * collectd: Implement `strerror_r' if the libc doesn't provide it.
272 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
273 a deadlock or delay when shutting down the daemon.
274 * snmp plugin: Fix a memory leak.
276 2007-10-24, Version 4.1.3
277 * collectd: A build issue under Solaris has been resolved by renaming
279 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
280 be more thread-safe otherwise by locking calls to the library.
282 2007-09-28, Version 4.1.2
283 * apcups plugin: Fix reporting of the `load percent' data.
284 * wireless plugin: Correct the handling of cards returning signal and
285 noise quality as percentage.
286 * perl plugin: Fix a possible buffer overflow in get_module_name().
287 * build system: Further improve the detection of libraries.
288 * netlink plugin: Build issues under some older versions of the Linux
289 includes (i. e. Debian Sarge) have been fixed.
290 * snmp plugin: Fix a potential segfault when a host times out. Add
291 support for the `timeticks' type.
293 2007-09-12, Version 4.1.1
294 * Build system: The detection of `libnetlink' has been improved.
295 * collectd: The documentation has been fixed in numerous places.
296 * exec plugin: Setting the group under which to run a program has been
298 * collectd: The `sstrerror' function was improved to work correctly
299 with the broken GNU version of `strerror_r'.
300 * collectd: Write an error message to STDERR when loading of a plugin
302 * apcups plugin: Fix the `types' used to submit the values: They still
303 has an `apcups_' prefix which doesn't work anymore.
304 * rrdtool plugin: Create new RRD-files with the `begin' time set to
305 whatever the client thinks is `now'..
307 2007-09-01, Version 4.1.0
308 * Build system: The build system has been changed to automatically
309 disable all plugins, which are missing dependencies. The dependency
310 checking has been removed from the plugins themselves to remove
312 * Flexible interval: The interval of collected data is now sent along
313 with the data itself over the network, so that the interval-settings
314 of server and clients no longer needs to match.
315 * netlink plugin: The new `netlink' plugin connects to the Linux
316 kernel using a netlink socket and uses it to query information about
317 interfaces, qdiscs and classes.
318 * rrdtool plugin: The cache is now dumped to disk in an extra thread
319 to not block data collection.
320 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
321 network devices, such as switches, routers, thermometers, rack
322 monitoring servers, etc. The collectd-snmp(5) manpage documents this
324 * unixsock plugin: Added the `LISTVAL' command.
325 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
326 of music played with xmms.
328 2007-09-28, Version 4.0.9
329 * apcups plugin: Fix reporting of the `load percent' data.
330 * wireless plugin: Correct the handling of cards returning signal and
331 noise quality as percentage.
332 * perl plugin: Fix a possible buffer overflow in get_module_name().
334 2007-09-12, Version 4.0.8
335 * collectd: The `sstrerror' function was improved to work correctly
336 with the broken GNU version of `strerror_r'.
337 * collectd: Write an error message to STDERR when loading of a plugin
339 * apcups plugin: Fix the `types' used to submit the values: They still
340 has an `apcups_' prefix which doesn't work anymore.
341 * rrdtool plugin: Create new RRD-files with the `begin' time set to
342 whatever the client thinks is `now'..
344 2007-08-26, Version 4.0.7
345 * documentation: Some typos have been fixed and some information has
347 * build system: Many fixes for detecting libraries in unusual places,
348 such as on RedHat systems. The affected libraries are `libcurl',
349 `libmysql', and `libupsclient'.
350 * network plugin: Allow the `Port' option to be specified as a number
351 (i. e. without quotes).
352 * nut plugin: A fix allows linking the nut plugin against
353 libupsclient, version >= 2.2.0.
354 * processes plugin: Fix a potential segmentation fault.
356 2007-07-30, Version 4.0.6
357 * sensors plugin: Fix the ignorelist functionality: Only the `type
358 instance' was used to match against the list, but the documentation
359 told otherwise. This release fixes the code, so it complies with the
361 * syslog plugin: Call `openlog' right when the plugin is loaded, so
362 configuration messages will end up in the logging facility.
363 * conrtib/fedora: The contributed specfile for Fedora has been
366 2007-07-05, Version 4.0.5
367 * Portability: More fixes for OpenBSD have been included.
369 2007-06-24, Version 4.0.4
370 * cpu plugin: Fixed the Solaris code.
371 * dns plugin: Fixed a build issue for OpenBSD.
372 * interface plugin: Fixed the Solaris code.
373 * load plugin: Fixed the alternative `/proc' Linux code.
374 * memory plugin: Fixed the Solaris code.
375 * oconfig: Don't require `-lfl' anymore.
377 2007-06-19, Version 4.0.3
378 * cpu plugin: Fix the Darwin / Mac OS X code.
379 * ping plugin: Use the return value of `getpid', not its address.
380 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
381 initialized correctly.
382 * configure: Added `--with-nan-emulation' to aid cross compilation.
384 2007-06-12, Version 4.0.2
385 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
386 they're given in numerically form.
388 2007-06-07, Version 4.0.1
389 * iptables plugin: A bug in the configuration routine has been fixed.
390 Setting a comment in the configfile will no longer cause a
393 2007-06-03, Version 4.0.0
394 * collectd: The plugin-infrastructure has been changed to allow for
395 more types of plugins, namely `write' and `log' plugins.
396 * collectd: The read-function has been changed to read many plugins in
397 parallel, using threads. Thus, plugins generally need to use
398 thread-safe functions from now on.
399 * collectd: The '-t' command line options allows to perform syntax tests
400 of the configuration file and exit immediately.
401 * csv plugin: The new `csv' plugin handles output to `comma separated
403 * rrdtool plugin: The new `rrdtool' plugin handles output to
404 RRD-files. Data can be cached to combine multiple updates into one
405 write to increase IO-performance.
406 * network plugin: The new `network' plugin handles IO via the network.
407 It implements a different, much more extensible protocol which can
408 combine many values in one packet, decreasing the number of UDP-
409 packets being sent. It can read from and send to the network and
410 with the appropriate configuration even forward packets to other
412 * unixsock plugin: The new `unixsock' plugin provides an interface to
413 communicate with the daemon while it is running. Right now the
414 commands `GETVAL' and `PUTVAL' are implemented, but more are to
416 * perl plugin: The new `perl' plugin allows you to write extensions
417 for collectd in the scripting-language Perl.
418 * logfile plugin: The new `logfile' plugin writes logmessages to files
420 * syslog plugin: The new `syslog' plugin sends logmessages to the
421 system's syslog daemon.
422 * entropy plugin: The new `entropy' plugin collects the amount of
423 entropy currently being available to the system.
424 * exec plugin: The new `exec' plugin forks child processes and reads
425 back values provided by the forked processes.
426 * iptables plugin: The new `iptables' plugin reads counters from
427 iptables rules. Thanks to Sjoerd van der Berg for contributing this
429 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
430 to Peter Holik for contributing this plugin.
431 * nut plugin: The new `nut' plugin connects the upsd of the `network
432 ups tools' and reads information about the connected UPS.
433 * apache plugin: Support for lighttpd's `BusyServers' (aka.
434 connections) field was added by Florent Monbillard.
435 * collectd-nagios: The new `collectd-nagios' binary queries values
436 from collectd, parses them and exits according to Nagios-standards.
437 * manpages: The manpages have been improved a lot.
439 2007-09-28, Version 3.11.7
440 * wireless plugin: Correct the handling of cards returning signal and

447 * configure: Added `AC_SYS_LARGEFILE' for LFS.
448 * ntpd plugin: Fix a potential buffer overflow.
449 * processes plugin: Fix a bug when run under Linux 2.4. All processes
450 were accounted as `zombies'.
452 2007-04-10, Version 3.11.4
453 * dns plugin: Change the order of includes to make the plugin compile
456 2007-03-30, Version 3.11.3
457 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
458 of the unused `COLLECT_KSTAT'.
460 2007-02-11, Version 3.11.2
461 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
462 NULL-pointer may have been passed to `printf' which causes a
463 segfault with some libcs.
465 2007-02-10, Version 3.11.1
466 * df plugin: Some wrong defines have been fixed so the plugin works
468 * dns plugin: The usage of a struct has been fixed to work with
470 * processes plugin: Some missing defines have been added so the plugin
471 compiles cleanly under FreeBSD and presumably other UNIXes.
473 2006-12-22, Version 3.11.0
474 * collectd: The new command line option `-P' makes it easier for
475 distributors to change the location of PID-files.
476 * collectd: The daemon shuts down faster now which makes it easier to
477 write init.d-scripts for it.
478 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
479 caused problems every now and then.
480 * df plugin: New config options allow to ignore certain mountpoints,
481 filesystem types or devices.
482 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
483 and interprets it. It collects traffic as well as qtype, opcode and
485 * email plugin: Sebastian Harl has contributed this plugin which
486 counts received mails in categories (e. g. ham, spam, virus), spam
487 score (as given by SpamAssassin) and check types.
488 * mbmon plugin: Flavio Stanchina has contributed this plugin which
489 uses `mbmon' to gather information from sensors on the motherboard.
490 * processes plugin: Collect detailed statistics for configured
491 processes, that's process and thread count, CPU usage, resident
492 segment size and pagefaults.
493 * multimeter plugin: Peter Holik contributed a new plugin which
495 * sensors plugin: Lubos Stanek has put much effort into improving this
496 plugin, including `extended naming', collection of voltage values
497 and the possibility to ignore certain values.
499 2006-12-21, Version 3.10.4
500 * Max Kellermann has identified a bug in the server routine: When
501 opening a socket fails the daemon will (re)try opening the socket in
502 an endless loop, ultimately leading to a `EMFILE' error.
504 2006-11-04, Version 3.10.3
505 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
506 ntpd's reply was sent in more than one packet, the buffer size was
507 calculated incorrectly, resulting in the reading of uninitialized or
510 2006-11-01, Version 3.10.2
511 * The sample config file has been improved.
512 * Errors in the manpages have been corrected.
513 * The ping-plugin now adds hosts during initialization, not during
514 startup. This speeds up startup when no network connectivity is
515 available. Also, the hosts are being added later when the network is
517 * Improved BSD-support for the df-plugin.
518 * Fixed syntax errors in the swap-plugin for Mac OS X.
519 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
521 * Don't disable the mysql-plugin if connecting to the database fails
522 during initialization. Instead, try again in increasing intervals.
524 2006-07-19, Version 3.10.1
525 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
526 the apcups cannot be reached, unconnected sockets will pile up and
527 eventually lead to `Too many open files' errors.
529 2006-07-09, Version 3.10.0
530 * The `disk' plugin has been ported to Darwin.
531 * The `battery' plugin should work on many Apple computers now.
532 * The `traffic' plugin can now ignore certain interfaces. Also,
533 statistics for sent/received packets and errors have been added.

535 to Anthony Gialluca for contributing this plugin and providing me
536 with a test environment :)
537 * A plugin for monitoring an NTP instance and the local clock drift
540 2006-06-25, Version 3.9.4
541 * The Solaris code in the `swap' plugin has been changed to reflect
542 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
544 * The debugging system has been fixed to work with the Sun libc.
545 * When built without librrd the variable `operating_mode' could be
546 uninitialized. Thanks to David Elliot for reporting the bug.
548 2006-06-01, Version 3.9.3
549 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
550 operating systems also profit from the changes, but I wasn't able to
552 * Changed the build system to find the netinet-includes under FreeBSD
553 and therefore successfully build the `liboping' library there.
555 2006-05-09, Version 3.9.2
556 * Applied a patch to the `liboping' library. Due to a bug in the
557 sequence checking the `ping' plugin stopped working after
558 approximately 7.6 days.
560 2006-05-09, Version 3.8.5
561 * Applied a patch to the `liboping' library. Due to a bug in the
562 sequence checking the `ping' plugin stopped working after
563 approximately 7.6 days.
565 2006-04-21, Version 3.9.1
566 * Build issues with Solaris and possible other architectures have been
568 * Problems when building the `apache'-plugin without `libcurl' have
570 * A bug in the `ping' plugin has been fixed. Sorry folks.
572 2006-04-02, Version 3.9.0
573 * A plugin to monitor the Apache webserver has been added.
574 <http://httpd.apache.org/>
575 * A plugin to collect statistics about virtual servers using VServer.
576 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

579 strength, link quality and noise ratio..
580 * A plugin for Apple hardware sensors has been added.
581 * An option to compile collectd with different `step' and `heartbeat'
582 settings has been added. The size of RRAs is no longer static but
583 calculated based on the settings for `step' and `width'.
584 * The `ping' plugin can now be configured to use a certain TTL.
585 * A plugin to monitor the hardware sensors of Apple computers has been
587 * The plugins `cpu', `memory', `processes' and `traffic' have been
588 ported to Mach/Darwin (Mac OS X).
589 * The `log mode' has been contributed by Christophe Kalt. It writes
590 the data into text files rather than RRD files.
592 2006-04-09, Version 3.8.4
593 * Applied patch by Vincent Stehlé which improves the disk-name
594 resolution in the `hddtemp' plugin for Linux systems.
596 2006-04-02, Version 3.8.3
597 * Applied a patch by James Byers: The MySQL plugin was not working
598 with MySQL 5.0.2 or later.
600 2006-03-14, Version 3.8.2
601 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
602 the GNU libc, because it points to `/etc/fstab' rather than
605 2006-03-13, Version 3.8.1
606 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
607 * Fixes in the debian `postinst' and `init.d' scripts.
609 2006-03-09, Version 3.8.0
610 * The `ping' plugin no longer uses `libping' but a self written
611 library named `liboping'. With this library it's possible to ping
612 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
614 2006-02-18, Version 3.7.2
615 * A simple bug in the `battery' plugin has been fixed. It should now
616 work with ACPI based batteries as well. Thanks to Sebastian for
618 * Fixing a bug that prevented collectd to be built without librrd.
619 Thanks to Werner Heuser for reporting it.
621 2006-02-04, Version 3.7.1
622 * The new network code has been improved to build with older versions

628 * The `battery' plugin has been added. It collects information about
630 * The MySQL plugin has been improved: It now writes two more RRD
631 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
632 * The `cpufreq' plugin now reads another file since the file it did
633 read so far causes much overhead in the kernel. Also, you need root
634 to read the old file, but not to read the new one.
635 * The `hddtemp' plugin can now be configured to connect to another
636 address and/or port than localhost.
637 * The `df' plugin now prefers `statvfs' over `statfs'.
638 * The network code has been rewritten. collectd now supports unicast
639 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
640 be set in the configfile.
642 2006-01-24, Version 3.6.2
643 * Due to a bug in the configfile handling collectd wouldn't start in
644 client mode. This released fixes this.
646 2006-01-20, Version 3.6.1
647 * Due to a bug in `configure.in' all modules and the binary were
648 linked against `libmysqlclient'. This issue is solved by this
651 2006-01-17, Version 3.6.0
652 * A config file has been added. This allows for loading only specific
654 * A `df' plugin has been added.
655 * A `mysql' plugin has been added.
656 * The `ping' plugin doesn't entirely give up hope when a socket error
657 occurred, but will back of and increase the intervals between tries.
659 2006-01-21, Version 3.5.2
660 * Fixed yet another bug in the signal handling.. Stupid typo..
661 * Improved the ping plugin to not give up on socket errors (backport
664 2005-12-18, Version 3.5.1

666 * SIGINT and SIGTERM are now handled correctly.
668 2005-12-16, Version 3.5.0 (Revision 326)
669 * A bug in the `load' module under Solaris has been fixed.
670 * The `users' module has been contributed by Sebastian Harl. It counts
671 currently logged in users.
672 * The CPU module now works under FreeBSD without the use of
673 `libstatgrab', however SMP support is missing.
674 * The default directories for the RRD files and the PID file now
675 depend on the compile time setting of `localstatedir'.
677 2005-11-15, Version 3.4.0 (Revision 236)
678 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
679 from gentoo's bugzilla for writing the patch.
680 * The build dependency for librrd has been removed. Binaries built
681 without librrd are client-only and will multicast their value as
682 with the `-c' argument.
683 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
684 * The newly introduced `-f' switch prevents daemon initialization
685 (forking, closing standard filehandles, etc.) Thanks to Alvaro
686 Barcellos for this patch.
688 2005-11-04, Version 3.3.0 (Revision 216)
689 * New modules have been added:
690 - `serial', for monitoring traffic on the serial interfaces
691 - `nfs', for graphing NFS procedure calls
692 - `tape', traffic from/to tape devices
693 * The memory.rrd now accepts more than 4Gig of memory.
695 2005-10-26, Version 3.2.0 (Revision 200)
696 * Support for graphing the processes has been added (thanks to Lyonel

699 between polls up to one day.
700 * The init.d files have been improved.
701 * Problems with the spec file have been fixed.
703 2005-10-16, Version 3.1.0 (Revision 194)
704 * Added the `setsid' syscall to the startup code.
705 * Support for hddtemp has been added (thanks to Vincent Stehlé)
707 2005-09-30, Version 3.0.0 (Revision 184)
708 * The ability to send/receive data to/from the network (think
709 multicast) has been added.
710 * Modules have been split up into shared libraries can be loaded at
711 runtime. The biggest advantage is that the core program doesn't need
712 to be linked against an external library.
713 * A patch by George Kargiotakis has been applied: It fixes the sensors
714 behaviour then more than one sensor is being queried.
716 2005-09-16, Version 2.1.0 (Revision 172)
717 * A module for swap statistics has been added.
719 2005-09-09, Version 2.0.0 (Revision 135)
720 * Filenames can no longer be configured at program startup. The only
721 options as of this version are the directory and ping hosts.
722 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
723 Soft-IRQ statistics are added to `System'.
724 * Diskstats now collect read and write bytes, not sectors.
725 * Ping statistics can now be collected for more than one host. There
726 is no default any more: If no host is given no host will be pinged.
727 * A self-written patch for libping has been applied so it builds
730 2005-09-01, Version 1.8.1 (Revision 123)
731 * Much improved configure-script: libraries and features may now be
733 * More detailed warnings/error messages when RRD update fails.
735 2005-08-29, Version 1.8.0:
736 * Support for collecting disk statistics under Solaris.
738 2005-08-25, Version 1.7.0:
739 * Support for libstatgrab[1] for load, memory usage and network
740 traffic. CPU- and disk-usage are not (yet) supported, since
741 libstatgrab returns insufficient information. I will contact the
743 * Improved the CPU-initialization code for Solaris. Apparently CPUs
744 aren't necessarily counted linear which is now handled correctly.
745 [1]: http://www.i-scream.org/libstatgrab/
747 2005-08-21, Version 1.6.0:
748 * Basic support for Solaris: System load and cpu-usage can be
749 collected under Solaris, too. Other stats will follow later.
750 * Many fixes in the autoconf-script
751 * Collection/Museum scripts have been added under contrib/museum
752 * collectd may now be started in unprivileged mode, though ping
753 statistics will not work.
755 2005-07-17, Version 1.5.1:
756 * Diskstats-RRDs now use major/minor for naming. Some systems have
757 weird strings as disk-names..
759 2005-07-17, Version 1.5:
760 * A new module, diskstats, has been added. It collects information
761 about the disks and partitions.
763 2005-07-11, Version 1.4.2:
764 * The meminfo module has been changed to work with more platforms
765 and/or kernel versions.
767 2005-07-10, Version 1.4.1: Correct traffic stats
768 * The traffic rrd-file is now created with DS-type `COUNTER' which I
769 forgot to correct when I changed that module.
771 2005-07-09, Version 1.4: More traffic stats
772 * Traffic is now collected for all interfaces that can be found
773 * Temperature-statistics are read from lm-sensors if available
775 2005-07-08, Version 1.3: CPU stats
776 * Collecting CPU statistics now
778 2004-07-12, Version 1.2: Using syslog
779 * collectd is now using the syslog facility to report errors, warnings
781 * The default directory is now /var/db/collectd
783 2004-07-10, Version 1.1: Minor changes
784 * Nothing really useful to say ;)
786 2004-07-09, Version 1.0: Initial Version
787 * The following modules are provided:
