41 X desktop using the structure defined in the `Desktop Notification
43 * notify_email plugin: This new plugin sends out notifications via
44 email, using the `esmtp' library.
45 * onewire plugin: The new experimental(!) onewire plugin reads values,
46 such as temperatures, from sensors connected to the computer via the
48 * perl plugin: Improved synchronized access to internal data structures
49 and fixed a possible dead-lock.
50 * perl plugin: Added the ability to flush certain identifiers and marked
51 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
53 * perl plugin: Added the ability to configure Perl plugins.

103 values under Solaris.
104 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
105 * vserver plugin: Remove usage of the thread-unsafe `readdir'
107 * wireless plugin: Work around incorrect noise and power values

115 * collectd-nagios: Fix the protocol used to communicate with the
117 * perl plugin: Fail noisily, but don't shutdown the daemon, if
118 initialization has errors. An issue with Perl 5.10 has been fixed.
119 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
120 René Rebe and Siegmund Gorr for reporting this.
122 2008-05-06, Version 4.4.0
123 * collectd: Internal code cleanups.
124 * collectd: Added support for a `Flush' command in the unixsock and
125 exec plugins. This command can be used to force a plugin (or all) to
126 flush its values to disk.
127 * collectd: Thresholds can now be configured to apply to one data
128 source only, making it possible to configure different thresholds
129 for each data source.

139 sensor values via IPMI, the intelligent platform management
141 * iptables plugin: The iptc library that is used by the iptables
142 plugin has been added to the distribution, because it is not
143 provided by all distributions and removed from at least one.
144 * powerdns plugin: The new powerdns plugin reads statistics from an
145 authoritative or a recursing PowerDNS name server.
146 * rrdtool plugin: The size of the files generated with the default
147 configuration has been decreased.

176 * build system: Improved detection of several libraries, especially if
177 they are in non-standard paths.
178 * build system: Portability fixes: Automatically define "_REENTRANT"
179 if the libc expects it.
180 * collectd: Error and warning messages have been improved.
181 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
183 * apache plugin: Allocate new memory when reading a webpage instead of
184 using a buffer of static size.
185 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
187 * hddtemp plugin: Error and warning messages have been improved.
188 * sensors plugin: Fix sensor collection for some chip types.
190 2008-03-29, Version 4.3.2
191 * collectd: Fix configuration of the `FailureMax', `WarningMax', and

202 + Use `memcpy' when constructing/parsing a package to avoid
203 alignment problems on weird architectures, such as Sparc.
204 + Translate doubles to/from the x86 byte representation to ensure
205 cross-platform compatibility.
206 * ping plugin: Correct the handling of the `TTL' setting.
207 * swap plugin: Reapply a patch for Solaris.
208 * tcpconns plugin: Portability improvements.
210 2008-02-18, Version 4.3.0
211 * collectd: Notifications have been added to the daemon. Notifications
212 are status messages that may be associated with a data instance.
213 * collectd: Threshold checking has been added to the daemon. This
214 means that you can configure threshold values for each data
215 instance. If this threshold is exceeded a notification will be
217 * collectd: The new `FQDNLookup' option tells the daemon to use the
218 full qualified domain name as the hostname, not just the host part
219 es returned by `gethostname(2)'.
220 * collectd: Support for more than one `TypesDB' file has been added.
221 This is useful when one such file is included in a package but one
222 wants to add custom type definitions.
223 * collectd: The `Include' config option has been expanded to handle
224 entire directories and shell wildcards.
225 * collectdmon: The new `collectdmon' binary detects when collectd

235 domain name lookups in this plugin.
236 * perl plugin: Many internal changes added support for handling multiple
237 threads making the plugin reasonably usable inside collectd. The API has
238 been extended to support notifications and export global variables to
239 Perl plugins; callbacks now have to be identified by name rather than a
240 pointer to a subroutine. The plugin is no longer experimental.
241 * uuid plugin: The new UUID plugin sets the hostname to an unique
242 identifier for this host. This is meant for setups where each client
243 may migrate to another physical host, possibly going through one or
244 more name changes in the process. Thanks to Richard Jones from
245 Red Hat's Emerging Technology group for this plugin.
246 * libvirt: The new libvirt plugin uses the `libvirt' library to query
247 CPU, disk and network statistics about guest systems on the same
248 physical server. Thanks to Richard Jones from Red Hat's Emerging
249 Technology group for this plugin.
251 2008-04-22, Version 4.2.7
252 * build system: Improved detection of several libraries, especially if
253 they are in non-standard paths.

255 if the libc expects it.
256 * collectd: Error and warning messages have been improved.
257 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
259 * apache plugin: Allocate new memory when reading a webpage instead of
260 using a buffer of static size.
261 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
263 * hddtemp plugin: Error and warning messages have been improved.

270 * wireless plugin: Fix reading noise value.
272 2008-03-04, Version 4.2.5
273 * apache plugin: Improved initialization and error messages.
274 * exec plugin: Set supplementary group IDs.
276 + Create separate threads for reading from the socket and parsing
277 and dispatching incoming packets. Versions prior to this may have
278 problems in high-load situations, where the socket receive buffers
279 overflows, resulting in gaps in the data.
280 + Use `memcpy' when constructing/parsing a package to avoid
281 alignment problems on weird architectures, such as Sparc.
282 + Translate doubles to/from the x86 byte representation to ensure
283 cross-platform compatibility.
284 * ping plugin: Correct the handling of the `TTL' setting.
285 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
286 * swap plugin: Reapply a patch for Solaris.
287 * tcpconns plugin: Portability improvements.
289 2008-01-21, Version 4.2.4
290 * unixsock plugin: A bug in the unixsock plugin caused it not to set
291 the permission on the socket as documented in the manpage. Thanks to
292 Evgeny Chukreev for fixing this issue.
293 * collectd: The documentation has been improved.
295 2007-12-28, Version 4.2.3
296 * sensors plugin: Updated the plugin to build and work with version 3
297 of the libsensors library.
299 2007-12-15, Version 4.2.2
300 * nginx plugin: Incorrect comparison of strings lead to a segfault
301 when using the plugin. Thanks to Saulius Grigaliunas for fixing
303 * logfile plugin: The config option `Timestamp' was handled
304 incorrectly and basically always active. Thanks to Luke Heberling
307 2007-11-08, Version 4.2.1
308 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
310 * snmp plugin: Fix a memory leak.
312 2007-10-27, Version 4.2.0
313 * collectd: The new config option `Include' lets you include other
314 configfiles and thus split up your config into smaller parts. This
315 may be especially interesting for the snmp plugin to keep the data
316 definitions separate from the host definitions.
317 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
318 (number of connections, octets and packets for each service and
319 destination). Thanks to Sebastian Harl for this plugin.
320 * memcached plugin: The new `memcached' plugin connects to a memcached
321 daemon process and collects statistics of this distributed caching
322 system. Thanks to Antony Dovgal for contributing this plugin.
323 * nginx plugin: The new `nginx' plugin reads the status page of an
324 nginx daemon and saves the handled connections and requests.
325 * perl plugin: Many changes, including the added `EnableDebugger'
326 config option which lets you debug your Perl plugins more easily.
327 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
328 be more thread-safe otherwise by locking calls to the library.
329 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
330 correct the values returned by SNMP-agents. If a <data> block is
331 defined as `table' the instance is now optional. The sequence number
332 is used as the type-instance in this case. The new `InstancePrefix'
333 option allows to add arbitrary prefixes to the type-instance.
334 * tcpconns plugin: The new `tcpconns' plugin collects the number of
335 certain TCP connections and what state they're in. This can be used
336 to see how many connections your FTP server has to handle or how
337 many outgoing connections your mailserver has open.
339 2008-01-11, Version 4.1.6
340 * unixsock plugin: A bug in the unixsock plugin caused it not to set

355 `--with-libnetsnmp' has been fixed.
356 * collectd: Implement `strerror_r' if the libc doesn't provide it.
357 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
358 a deadlock or delay when shutting down the daemon.
359 * snmp plugin: Fix a memory leak.
361 2007-10-24, Version 4.1.3
362 * collectd: A build issue under Solaris has been resolved by renaming
364 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
365 be more thread-safe otherwise by locking calls to the library.
367 2007-09-28, Version 4.1.2
368 * apcups plugin: Fix reporting of the `load percent' data.
369 * wireless plugin: Correct the handling of cards returning signal and
370 noise quality as percentage.

379 * Build system: The detection of `libnetlink' has been improved.
380 * collectd: The documentation has been fixed in numerous places.
381 * exec plugin: Setting the group under which to run a program has been
383 * collectd: The `sstrerror' function was improved to work correctly
384 with the broken GNU version of `strerror_r'.
385 * collectd: Write an error message to STDERR when loading of a plugin
387 * apcups plugin: Fix the `types' used to submit the values: They still
388 has an `apcups_' prefix which doesn't work anymore.
389 * rrdtool plugin: Create new RRD-files with the `begin' time set to
390 whatever the client thinks is `now'..
392 2007-09-01, Version 4.1.0
393 * Build system: The build system has been changed to automatically
394 disable all plugins, which are missing dependencies. The dependency
395 checking has been removed from the plugins themselves to remove
397 * Flexible interval: The interval of collected data is now sent along
398 with the data itself over the network, so that the interval-settings
399 of server and clients no longer needs to match.
400 * netlink plugin: The new `netlink' plugin connects to the Linux
401 kernel using a netlink socket and uses it to query information about
402 interfaces, qdiscs and classes.
403 * rrdtool plugin: The cache is now dumped to disk in an extra thread
404 to not block data collection.
405 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
406 network devices, such as switches, routers, thermometers, rack
407 monitoring servers, etc. The collectd-snmp(5) manpage documents this
409 * unixsock plugin: Added the `LISTVAL' command.
410 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
411 of music played with xmms.
413 2007-09-28, Version 4.0.9

417 * perl plugin: Fix a possible buffer overflow in get_module_name().
419 2007-09-12, Version 4.0.8
420 * collectd: The `sstrerror' function was improved to work correctly
421 with the broken GNU version of `strerror_r'.
422 * collectd: Write an error message to STDERR when loading of a plugin
424 * apcups plugin: Fix the `types' used to submit the values: They still
425 has an `apcups_' prefix which doesn't work anymore.
426 * rrdtool plugin: Create new RRD-files with the `begin' time set to
427 whatever the client thinks is `now'..
429 2007-08-26, Version 4.0.7
430 * documentation: Some typos have been fixed and some information has
432 * build system: Many fixes for detecting libraries in unusual places,
433 such as on RedHat systems. The affected libraries are `libcurl',
434 `libmysql', and `libupsclient'.
435 * network plugin: Allow the `Port' option to be specified as a number
436 (i. e. without quotes).
437 * nut plugin: A fix allows linking the nut plugin against
438 libupsclient, version >= 2.2.0.
439 * processes plugin: Fix a potential segmentation fault.
441 2007-07-30, Version 4.0.6
442 * sensors plugin: Fix the ignorelist functionality: Only the `type
443 instance' was used to match against the list, but the documentation
444 told otherwise. This release fixes the code, so it complies with the
446 * syslog plugin: Call `openlog' right when the plugin is loaded, so
447 configuration messages will end up in the logging facility.
448 * conrtib/fedora: The contributed specfile for Fedora has been
451 2007-07-05, Version 4.0.5
452 * Portability: More fixes for OpenBSD have been included.

471 they're given in numerically form.
473 2007-06-07, Version 4.0.1
474 * iptables plugin: A bug in the configuration routine has been fixed.
475 Setting a comment in the configfile will no longer cause a
478 2007-06-03, Version 4.0.0
479 * collectd: The plugin-infrastructure has been changed to allow for
480 more types of plugins, namely `write' and `log' plugins.
481 * collectd: The read-function has been changed to read many plugins in
482 parallel, using threads. Thus, plugins generally need to use
483 thread-safe functions from now on.
484 * collectd: The '-t' command line options allows to perform syntax tests
485 of the configuration file and exit immediately.
486 * csv plugin: The new `csv' plugin handles output to `comma separated
488 * rrdtool plugin: The new `rrdtool' plugin handles output to
489 RRD-files. Data can be cached to combine multiple updates into one
490 write to increase IO-performance.
491 * network plugin: The new `network' plugin handles IO via the network.
492 It implements a different, much more extensible protocol which can
493 combine many values in one packet, decreasing the number of UDP-
494 packets being sent. It can read from and send to the network and
495 with the appropriate configuration even forward packets to other
497 * unixsock plugin: The new `unixsock' plugin provides an interface to
498 communicate with the daemon while it is running. Right now the
499 commands `GETVAL' and `PUTVAL' are implemented, but more are to
501 * perl plugin: The new `perl' plugin allows you to write extensions
502 for collectd in the scripting-language Perl.
503 * logfile plugin: The new `logfile' plugin writes logmessages to files
505 * syslog plugin: The new `syslog' plugin sends logmessages to the
506 system's syslog daemon.
507 * entropy plugin: The new `entropy' plugin collects the amount of
508 entropy currently being available to the system.
509 * exec plugin: The new `exec' plugin forks child processes and reads
510 back values provided by the forked processes.
511 * iptables plugin: The new `iptables' plugin reads counters from
512 iptables rules. Thanks to Sjoerd van der Berg for contributing this
514 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
515 to Peter Holik for contributing this plugin.
516 * nut plugin: The new `nut' plugin connects the upsd of the `network
517 ups tools' and reads information about the connected UPS.
518 * apache plugin: Support for lighttpd's `BusyServers' (aka.
519 connections) field was added by Florent Monbillard.
520 * collectd-nagios: The new `collectd-nagios' binary queries values
521 from collectd, parses them and exits according to Nagios-standards.
522 * manpages: The manpages have been improved a lot.
524 2007-09-28, Version 3.11.7
525 * wireless plugin: Correct the handling of cards returning signal and
526 noise quality as percentage.
528 2007-08-31, Version 3.11.6
529 * processes plugin: Fix a potential segmentation fault.
531 2007-05-29, Version 3.11.5
532 * configure: Added `AC_SYS_LARGEFILE' for LFS.
533 * ntpd plugin: Fix a potential buffer overflow.
534 * processes plugin: Fix a bug when run under Linux 2.4. All processes
535 were accounted as `zombies'.
537 2007-04-10, Version 3.11.4
538 * dns plugin: Change the order of includes to make the plugin compile
541 2007-03-30, Version 3.11.3
542 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
543 of the unused `COLLECT_KSTAT'.
545 2007-02-11, Version 3.11.2
546 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
547 NULL-pointer may have been passed to `printf' which causes a
548 segfault with some libcs.
550 2007-02-10, Version 3.11.1
551 * df plugin: Some wrong defines have been fixed so the plugin works
553 * dns plugin: The usage of a struct has been fixed to work with
555 * processes plugin: Some missing defines have been added so the plugin
556 compiles cleanly under FreeBSD and presumably other UNIXes.
558 2006-12-22, Version 3.11.0
559 * collectd: The new command line option `-P' makes it easier for
560 distributors to change the location of PID-files.
561 * collectd: The daemon shuts down faster now which makes it easier to
562 write init.d-scripts for it.
563 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
564 caused problems every now and then.
565 * df plugin: New config options allow to ignore certain mountpoints,
566 filesystem types or devices.
567 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
568 and interprets it. It collects traffic as well as qtype, opcode and
570 * email plugin: Sebastian Harl has contributed this plugin which
571 counts received mails in categories (e. g. ham, spam, virus), spam
572 score (as given by SpamAssassin) and check types.
573 * mbmon plugin: Flavio Stanchina has contributed this plugin which
574 uses `mbmon' to gather information from sensors on the motherboard.
575 * processes plugin: Collect detailed statistics for configured
576 processes, that's process and thread count, CPU usage, resident
577 segment size and pagefaults.
578 * multimeter plugin: Peter Holik contributed a new plugin which
580 * sensors plugin: Lubos Stanek has put much effort into improving this
581 plugin, including `extended naming', collection of voltage values
582 and the possibility to ignore certain values.
584 2006-12-21, Version 3.10.4
585 * Max Kellermann has identified a bug in the server routine: When
586 opening a socket fails the daemon will (re)try opening the socket in
587 an endless loop, ultimately leading to a `EMFILE' error.
589 2006-11-04, Version 3.10.3
590 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
591 ntpd's reply was sent in more than one packet, the buffer size was
592 calculated incorrectly, resulting in the reading of uninitialized or
595 2006-11-01, Version 3.10.2
596 * The sample config file has been improved.
597 * Errors in the manpages have been corrected.
598 * The ping-plugin now adds hosts during initialization, not during
599 startup. This speeds up startup when no network connectivity is
600 available. Also, the hosts are being added later when the network is
602 * Improved BSD-support for the df-plugin.
603 * Fixed syntax errors in the swap-plugin for Mac OS X.
604 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
606 * Don't disable the mysql-plugin if connecting to the database fails
607 during initialization. Instead, try again in increasing intervals.
609 2006-07-19, Version 3.10.1
610 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
611 the apcups cannot be reached, unconnected sockets will pile up and
612 eventually lead to `Too many open files' errors.
614 2006-07-09, Version 3.10.0
615 * The `disk' plugin has been ported to Darwin.
616 * The `battery' plugin should work on many Apple computers now.
617 * The `traffic' plugin can now ignore certain interfaces. Also,
618 statistics for sent/received packets and errors have been added.
619 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
620 to Anthony Gialluca for contributing this plugin and providing me
621 with a test environment :)
622 * A plugin for monitoring an NTP instance and the local clock drift
625 2006-06-25, Version 3.9.4
626 * The Solaris code in the `swap' plugin has been changed to reflect
627 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
629 * The debugging system has been fixed to work with the Sun libc.
630 * When built without librrd the variable `operating_mode' could be
631 uninitialized. Thanks to David Elliot for reporting the bug.
633 2006-06-01, Version 3.9.3
634 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
635 operating systems also profit from the changes, but I wasn't able to
637 * Changed the build system to find the netinet-includes under FreeBSD
638 and therefore successfully build the `liboping' library there.
640 2006-05-09, Version 3.9.2
641 * Applied a patch to the `liboping' library. Due to a bug in the
642 sequence checking the `ping' plugin stopped working after
643 approximately 7.6 days.
645 2006-05-09, Version 3.8.5
646 * Applied a patch to the `liboping' library. Due to a bug in the
647 sequence checking the `ping' plugin stopped working after
648 approximately 7.6 days.
650 2006-04-21, Version 3.9.1
651 * Build issues with Solaris and possible other architectures have been
653 * Problems when building the `apache'-plugin without `libcurl' have
655 * A bug in the `ping' plugin has been fixed. Sorry folks.
657 2006-04-02, Version 3.9.0
658 * A plugin to monitor the Apache webserver has been added.
659 <http://httpd.apache.org/>
660 * A plugin to collect statistics about virtual servers using VServer.
661 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
663 * A plugin for wireless LAN cards has been added. It monitors signal
664 strength, link quality and noise ratio..
665 * A plugin for Apple hardware sensors has been added.
666 * An option to compile collectd with different `step' and `heartbeat'
667 settings has been added. The size of RRAs is no longer static but
668 calculated based on the settings for `step' and `width'.
669 * The `ping' plugin can now be configured to use a certain TTL.
670 * A plugin to monitor the hardware sensors of Apple computers has been
672 * The plugins `cpu', `memory', `processes' and `traffic' have been
673 ported to Mach/Darwin (Mac OS X).
674 * The `log mode' has been contributed by Christophe Kalt. It writes
675 the data into text files rather than RRD files.
677 2006-04-09, Version 3.8.4
678 * Applied patch by Vincent Stehlé which improves the disk-name
679 resolution in the `hddtemp' plugin for Linux systems.
681 2006-04-02, Version 3.8.3
682 * Applied a patch by James Byers: The MySQL plugin was not working
683 with MySQL 5.0.2 or later.
685 2006-03-14, Version 3.8.2
686 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
687 the GNU libc, because it points to `/etc/fstab' rather than
690 2006-03-13, Version 3.8.1
691 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
692 * Fixes in the debian `postinst' and `init.d' scripts.
694 2006-03-09, Version 3.8.0
695 * The `ping' plugin no longer uses `libping' but a self written
696 library named `liboping'. With this library it's possible to ping
697 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
699 2006-02-18, Version 3.7.2
700 * A simple bug in the `battery' plugin has been fixed. It should now
701 work with ACPI based batteries as well. Thanks to Sebastian for
703 * Fixing a bug that prevented collectd to be built without librrd.
704 Thanks to Werner Heuser for reporting it.
706 2006-02-04, Version 3.7.1
707 * The new network code has been improved to build with older versions
709 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
710 to Tommie Gannert for this patch.
712 2006-01-30, Version 3.7.0
713 * The `battery' plugin has been added. It collects information about
715 * The MySQL plugin has been improved: It now writes two more RRD
716 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
717 * The `cpufreq' plugin now reads another file since the file it did
718 read so far causes much overhead in the kernel. Also, you need root
719 to read the old file, but not to read the new one.
720 * The `hddtemp' plugin can now be configured to connect to another
721 address and/or port than localhost.
722 * The `df' plugin now prefers `statvfs' over `statfs'.
723 * The network code has been rewritten. collectd now supports unicast
724 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
725 be set in the configfile.
727 2006-01-24, Version 3.6.2
728 * Due to a bug in the configfile handling collectd wouldn't start in
729 client mode. This released fixes this.
731 2006-01-20, Version 3.6.1
732 * Due to a bug in `configure.in' all modules and the binary were
733 linked against `libmysqlclient'. This issue is solved by this
736 2006-01-17, Version 3.6.0
737 * A config file has been added. This allows for loading only specific
739 * A `df' plugin has been added.
740 * A `mysql' plugin has been added.
741 * The `ping' plugin doesn't entirely give up hope when a socket error
742 occurred, but will back of and increase the intervals between tries.
744 2006-01-21, Version 3.5.2
745 * Fixed yet another bug in the signal handling.. Stupid typo..
746 * Improved the ping plugin to not give up on socket errors (backport
749 2005-12-18, Version 3.5.1
750 * The PID-file is now deleted correctly when shutting down the daemon.
751 * SIGINT and SIGTERM are now handled correctly.
753 2005-12-16, Version 3.5.0 (Revision 326)
754 * A bug in the `load' module under Solaris has been fixed.
755 * The `users' module has been contributed by Sebastian Harl. It counts
756 currently logged in users.
757 * The CPU module now works under FreeBSD without the use of
758 `libstatgrab', however SMP support is missing.
759 * The default directories for the RRD files and the PID file now
760 depend on the compile time setting of `localstatedir'.
762 2005-11-15, Version 3.4.0 (Revision 236)
763 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
764 from gentoo's bugzilla for writing the patch.
765 * The build dependency for librrd has been removed. Binaries built
766 without librrd are client-only and will multicast their value as
767 with the `-c' argument.
768 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
769 * The newly introduced `-f' switch prevents daemon initialization
770 (forking, closing standard filehandles, etc.) Thanks to Alvaro
771 Barcellos for this patch.
773 2005-11-04, Version 3.3.0 (Revision 216)
774 * New modules have been added:
775 - `serial', for monitoring traffic on the serial interfaces
776 - `nfs', for graphing NFS procedure calls
777 - `tape', traffic from/to tape devices
778 * The memory.rrd now accepts more than 4Gig of memory.
780 2005-10-26, Version 3.2.0 (Revision 200)
781 * Support for graphing the processes has been added (thanks to Lyonel
783 * If reading from hddtemp fails collectd will increase the time
784 between polls up to one day.
785 * The init.d files have been improved.
786 * Problems with the spec file have been fixed.
788 2005-10-16, Version 3.1.0 (Revision 194)
789 * Added the `setsid' syscall to the startup code.
790 * Support for hddtemp has been added (thanks to Vincent Stehlé)
792 2005-09-30, Version 3.0.0 (Revision 184)
793 * The ability to send/receive data to/from the network (think
794 multicast) has been added.
795 * Modules have been split up into shared libraries can be loaded at
796 runtime. The biggest advantage is that the core program doesn't need
797 to be linked against an external library.
798 * A patch by George Kargiotakis has been applied: It fixes the sensors
799 behaviour then more than one sensor is being queried.
801 2005-09-16, Version 2.1.0 (Revision 172)
802 * A module for swap statistics has been added.
804 2005-09-09, Version 2.0.0 (Revision 135)
805 * Filenames can no longer be configured at program startup. The only
806 options as of this version are the directory and ping hosts.
807 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
808 Soft-IRQ statistics are added to `System'.
809 * Diskstats now collect read and write bytes, not sectors.
810 * Ping statistics can now be collected for more than one host. There
811 is no default any more: If no host is given no host will be pinged.
812 * A self-written patch for libping has been applied so it builds
815 2005-09-01, Version 1.8.1 (Revision 123)
816 * Much improved configure-script: libraries and features may now be
818 * More detailed warnings/error messages when RRD update fails.
820 2005-08-29, Version 1.8.0:
821 * Support for collecting disk statistics under Solaris.
823 2005-08-25, Version 1.7.0:
824 * Support for libstatgrab[1] for load, memory usage and network
825 traffic. CPU- and disk-usage are not (yet) supported, since
826 libstatgrab returns insufficient information. I will contact the
828 * Improved the CPU-initialization code for Solaris. Apparently CPUs
829 aren't necessarily counted linear which is now handled correctly.
830 [1]: http://www.i-scream.org/libstatgrab/
832 2005-08-21, Version 1.6.0:
833 * Basic support for Solaris: System load and cpu-usage can be
834 collected under Solaris, too. Other stats will follow later.
835 * Many fixes in the autoconf-script
836 * Collection/Museum scripts have been added under contrib/museum
837 * collectd may now be started in unprivileged mode, though ping
838 statistics will not work.
840 2005-07-17, Version 1.5.1:
841 * Diskstats-RRDs now use major/minor for naming. Some systems have
842 weird strings as disk-names..
844 2005-07-17, Version 1.5:
845 * A new module, diskstats, has been added. It collects information
846 about the disks and partitions.
848 2005-07-11, Version 1.4.2:
849 * The meminfo module has been changed to work with more platforms
850 and/or kernel versions.
852 2005-07-10, Version 1.4.1: Correct traffic stats
853 * The traffic rrd-file is now created with DS-type `COUNTER' which I
854 forgot to correct when I changed that module.
856 2005-07-09, Version 1.4: More traffic stats
857 * Traffic is now collected for all interfaces that can be found
858 * Temperature-statistics are read from lm-sensors if available
860 2005-07-08, Version 1.3: CPU stats
861 * Collecting CPU statistics now
863 2004-07-12, Version 1.2: Using syslog
864 * collectd is now using the syslog facility to report errors, warnings
866 * The default directory is now /var/db/collectd
868 2004-07-10, Version 1.1: Minor changes
869 * Nothing really useful to say ;)
871 2004-07-09, Version 1.0: Initial Version
872 * The following modules are provided:
