200 caused wrong behavior with the persistency option. Thanks to Andrés
201 J. Díaz for fixing these problems.
202 * collectd: Handling of the `Include' configuration option has been
204 * rrdtool plugin: Make sure initialization is run only once. This

312 * filter subsystem: Allow `Chains' without default targets.
313 * liboping: A patch to comply with strict aliasing rules has been
315 * timediff match: Fix a typo: The match was registered with a wrong
316 name which prevented this match to be used as documented. Thanks to
317 Bruno Prémont for finding this problem.
318 * bind plugin: Fix collection of the cached RR sets. The number of RR
319 sets currently in the cache was collected as a counter value, which
320 is nonsense. Thanks to Bruno Prémont for implementing this.
321 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
322 primarily BSDs, don't take it well and crash.
323 * oracle plugin: Portability to 64 bit systems has been improved.
324 * postgresql plugin: The default configuration has been improved.
325 * rrdtool plugin: Fix a possible race condition: If the network plugin
326 is brought and dispatches a value before the rrdtool plugin is
327 initialized, the daemon may crash.
329 2009-02-22, Version 4.6.1
330 * collectd: Many documentation fixes.

340 user to use `matches' and `targets' to control value processing.
341 * collectd: The new `-T' command line argument allows more in-depth
342 testing of a configuration. Thanks to Doug MacEachern for the patch.
343 * collectd-nagios: The Nagios integration command has been updated to
344 use libcollectdclient. The `percentage' aggregation function has
345 been added. Thanks to Fabian Linzberger for the patch.
346 * libcollectdclient: A library which abstracts communication with the
347 unixsock plugin for clients has been added.

367 * curl plugin: This new plugin can be used to read web pages and parse
368 them using the same mechanism that's used in the tail plugin.
369 * dbi plugin: This new plugin allows you to connect to a variety of
370 relational databases and use SQL to gather custom statistics from
371 it. It is similar to the already existing PostgreSQL plugin but uses
372 libdbi to communicate with the database(s).
373 * interface plugin: Use the ignorelist framework when selecting /
374 ignoring interfaces. This allows one to use regular expressions to
375 select interfaces, too.
376 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
377 Thanks to Bruno Prémont for this patch.
378 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

400 * processes plugin: Stacksize and virtual memory usage statistics have
401 been added. Portability fixes.
402 * rrdcached plugin: This new plugin uses the (still in development)
403 RRD accelerator daemon, rrdcached. This daemon works very similar to
404 the original rrdtool plugin of collectd, but adds some more nice
406 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
409 2009-05-09, Version 4.5.4
410 * Build system, various plugins: Many build fixes for FreeBSD,

422 Tomasz Pala for the patch.
423 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
425 * rrdtool plugin: Fix a possible race condition: If the network plugin
426 is initialized and dispatches a value before the rrdtool plugin is
427 initialized, the daemon may crash.
428 * memory plugin: Fix a potential problem under Solaris.
430 2009-02-22, Version 4.5.3
431 * build system: The check for libupsclient even when `pkg-config' is
433 * collectd: Fix error handling in the global cache.
434 * Collectd::Unixsock: Error handling has been improved.
435 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
437 * ipmi plugin: Fix an off-by-one error which could cause segmentation
438 faults. Thanks to Peter Holik for his patch.

440 code. Thanks to "thated" for reporting this.
442 2009-01-02, Version 4.5.2
443 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
444 file may be in both locations, especially when the database was
445 installed in a non-standard path. Thanks to Dusty Doris for
447 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
448 Solaris, in the configure script automatically.
449 * build system, tcpconns plugin: Check for `kvm_nlist' and
450 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
451 library with similar functions to the BSD variant, but doesn't
452 provide these necessary functions.
453 * collectd.conf(5): Various fixes and clarifications.
454 * collectd: Remove a GNUism (unnamed unions), thus improving
456 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
457 This solves portability problems, especially for Solaris.
458 * dns plugin: Fix a portability problem with NetBSD.
459 * filecount plugin: Fix an off-by-one error. This error may cause a
461 * network plugin: Fix the handling of `type' in the network protocol.
462 Due to a programming mistake, only 4 or 8 bytes would be copied to a
463 much larger buffer. This caused the `type' to be transferred much
464 more often than necessary. In some cases, e. g. the `cpu' and
465 `cpufreq' plugins being used at the same time, data may be corrupted
466 in those files. Thanks to Bruno Prémont for debugging and reporting
468 * processes plugin: Fix a possible segmentation fault when specifying
469 invalid configuration options.
470 * unixsock plugin: Make sure the initialization function is run only
471 once. This resolves a file descriptor leak under systems which run
472 the initialization more than once, such as Solaris.
474 2008-10-16, Version 4.5.1
475 * build system: Change `--enable-<plugin>' to abort with an error if
476 dependencies are not met. Thanks to Bruno Prémont for the patch.
477 Also, the poisoning of various string functions has been restricted
479 * collectd: Fix a memory leak in the global value cache. With every
480 *missing* value a couple of bytes would be leaked. Another memory
481 leak in the configuration handling code has been fixed. Thanks to
482 Niraj Tolia for reporting these issues.
483 * collectd: Fix an off-by-one error in the ignorelist functionality.
484 When using regular expressions, the last character would be missing,
485 possibly matching differently from what one would expect.
486 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
488 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
489 Linzberger for reporting the bug.
490 * iptables plugin: Fix an off-by-one error. If a string was just one
491 character too long, it was truncated instead of reporting an error.
492 * network plugin: Fix a memory leak in the configuration handling
493 code. Thanks to Niraj Tolia for reporting this issue.
494 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
495 * postgresql plugin: Don't reopen connection during reinitialization.
496 This fixes a bug under Solaris and potentially other platforms.
497 Missing calls to `PQclear' have been added, too. This fixes memory
498 leaks. Thanks to ``Admin'' for reporting these bugs.
499 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
501 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
502 problems with some `libc's. Thanks to Matthias Lay for reporting the
505 2008-09-04, Version 4.5.0
506 * collectd: Added the ability to flush certain identifiers.
507 * collectd: The concept of `notification meta data' has been
509 * filecount plugin: The new filecount plugin counts the number of
510 files in a directory and its subdirectories.
511 * ipmi plugin: Sensor names have been changed to ensure unique names.
512 Notifications upon added and removed sensors can now be generated.
513 * notify_desktop plugin: This new plugin sends notifications to the
514 X desktop using the structure defined in the `Desktop Notification
516 * notify_email plugin: This new plugin sends out notifications via
517 email, using the `esmtp' library.
518 * onewire plugin: The new experimental(!) onewire plugin reads values,
519 such as temperatures, from sensors connected to the computer via the
521 * perl plugin: Improved synchronized access to internal data structures
522 and fixed a possible dead-lock.
523 * perl plugin: Added the ability to flush certain identifiers and marked
524 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
526 * perl plugin: Added the ability to configure Perl plugins.
527 * postgresql plugin: The new postgresql plugin collects statistics
528 about or from a PostgreSQL database.
529 * processes plugin: The `ProcessMatch' option has been added.
530 * rrdtool plugin: Implement throttling of the `update queue' to lessen
532 * tcpconns plugin: This plugin has been ported to OpenBSD.
533 * thermal plugin: The new thermal plugin collects system temperatures
534 using Linux ACPI thermal zone data.
536 2009-01-02, Version 4.4.5
537 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
538 file may be in both locations, especially when the database was
539 installed in a non-standard path. Thanks to Dusty Doris for
541 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
542 Solaris, in the configure script automatically.
543 * collectd.conf(5): Various fixes and clarifications.
544 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
545 portability problems, especially for Solaris.
546 * dns plugin: Fix a portability problem with NetBSD.
547 * network plugin: Fix the handling of `type' in the network protocol.
548 Due to a programming mistake, only 4 or 8 bytes would be copied to a
549 much larger buffer. This caused the `type' to be transferred much
550 more often than necessary. In some cases, e. g. the `cpu' and
551 `cpufreq' plugins being used at the same time, data may be corrupted
552 in those files. Thanks to Bruno Prémont for debugging and reporting
554 * unixsock plugin: Make sure the initialization function is run only
555 once. This resolves a file descriptor leak under systems which run
556 the initialization more than once, such as Solaris.
558 2008-10-16, Version 4.4.4
559 * build system: Change `--enable-<plugin>' to abort with an error if
560 dependencies are not met. Thanks to Bruno Prémont for the patch.
561 Also, the poisoning of various string functions has been restricted
563 * collectd: Fix a memory leak in the global value cache. With every
564 *missing* value a couple of bytes would be leaked. Another memory
565 leak in the configuration handling code has been fixed. Thanks to
566 Niraj Tolia for reporting these issues.
567 * collectd: Fix an off-by-one error in the ignorelist functionality.
568 When using regular expressions, the last character would be missing,
569 possibly matching differently from what one would expect.
570 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
572 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
573 Linzberger for reporting the bug.
574 * network plugin: Fix a memory leak in the configuration handling
575 code. Thanks to Niraj Tolia for reporting this issue.
576 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
577 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
578 problems with some `libc's. Thanks to Matthias Lay for reporting the
581 2008-09-01, Version 4.4.3
582 * collectd: Fix a memory leak in the threshold checking code.
583 * memcached plugin: Fix a too short timeout and a related file
585 * memory plugin: A typo in the libstatgrab code has been fixed.
586 * snmp plugin: Fix a possible memory leak.
588 2008-07-15, Version 4.4.2
589 * build system: Use pkg-config to detect the upsclient library.
590 * collectd: Try even harder to determine the endianess of the
591 architecture collectd is being built on.
592 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
594 * dns plugin: Fix compilation errors with BIND versions 19991001
596 * network plugin: Bugfix in the init routine: The init function
597 cleared a buffer regardless of its contents. This could lead to lost
598 values under Solaris.
599 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
600 * vserver plugin: Remove usage of the thread-unsafe `readdir'
602 * wireless plugin: Work around incorrect noise and power values
603 returned by some broken drivers.
605 2008-06-03, Version 4.4.1
606 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
607 to kyrone for reporting this.
608 * collectd: Fixed min/max output in notifications generated by
610 * collectd-nagios: Fix the protocol used to communicate with the
612 * perl plugin: Fail noisily, but don't shutdown the daemon, if
613 initialization has errors. An issue with Perl 5.10 has been fixed.
614 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
615 René Rebe and Siegmund Gorr for reporting this.
617 2008-05-06, Version 4.4.0
618 * collectd: Internal code cleanups.
619 * collectd: Added support for a `Flush' command in the unixsock and
620 exec plugins. This command can be used to force a plugin (or all) to
621 flush its values to disk.
622 * collectd: Thresholds can now be configured to apply to one data
623 source only, making it possible to configure different thresholds
624 for each data source.
625 * apache, nginx plugins: Added the possibility to disable host and/or
627 * ascent plugin: The new ascent plugin reads and parses the statistics
628 page of an Ascent server.
629 * cpu plugin: Support for the statgrab library has been added.
630 * disk plugin: The possibility to ignore certain disks or collect only
631 specific disks has been added.
632 * disk plugin: Support for the statgrab library has been added.
633 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
634 sensor values via IPMI, the intelligent platform management
636 * iptables plugin: The iptc library that is used by the iptables
637 plugin has been added to the distribution, because it is not
638 provided by all distributions and removed from at least one.
639 * powerdns plugin: The new powerdns plugin reads statistics from an
640 authoritative or a recursing PowerDNS name server.
641 * rrdtool plugin: The size of the files generated with the default
642 configuration has been decreased.
643 * tail plugin: The new tail plugin can be used to gather statistics by
644 continuously reading from log files.
645 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
646 TeamSpeak2 server and collects statistics about the number of users
647 and number of channels.
648 * users plugin: Support for the statgrab library has been added.
649 * vmem plugin: The new vmem plugin collects very detailed statistics
650 about the virtual memory subsystem of Linux.
652 2008-08-30, Version 4.3.4
653 * Build system: Improved detection of and linking with the statgrab
655 * collectd: Portability fixes, especially to determine endianess more
657 * Various plugins: Fix format strings.
658 * disk plugin: A fix for giving disks under Linux 2.4 the right names
659 again has been applied.
660 * memcached plugin: Fix a too short timeout and a related file
662 * memory plugin: A typo in the libstatgrab code has been fixed.
663 * network plugin: A fix in the initialization function solves problems
665 * nginx plugin: A thread-unsafe function has been replaced.
666 * vserver plugin: A thread-unsafe function has been replaced.
667 * wireless plugin: A work-around for broken wireless drivers has been
670 2008-04-22, Version 4.3.3
671 * build system: Improved detection of several libraries, especially if
672 they are in non-standard paths.
673 * build system: Portability fixes: Automatically define "_REENTRANT"
674 if the libc expects it.
675 * collectd: Error and warning messages have been improved.
676 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
678 * apache plugin: Allocate new memory when reading a webpage instead of
679 using a buffer of static size.
680 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
682 * hddtemp plugin: Error and warning messages have been improved.
683 * sensors plugin: Fix sensor collection for some chip types.
685 2008-03-29, Version 4.3.2
686 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
687 `Persist' threshold options.
688 * collectd: Fix handling of missing values in the global value cache.
689 * collectd: Improved error messages when parsing the configuration.
690 * sensors plugin: Fix temperature collection with libsensors4.
691 * unixsock plugin: Fix mixed input and output operation on streams.
692 * wireless plugin: Fix reading noise value.
694 2008-03-05, Version 4.3.1
695 * exec plugin: Set supplementary group IDs.
697 + Use `memcpy' when constructing/parsing a package to avoid
698 alignment problems on weird architectures, such as Sparc.
699 + Translate doubles to/from the x86 byte representation to ensure
700 cross-platform compatibility.
701 * ping plugin: Correct the handling of the `TTL' setting.
702 * swap plugin: Reapply a patch for Solaris.
703 * tcpconns plugin: Portability improvements.
705 2008-02-18, Version 4.3.0
706 * collectd: Notifications have been added to the daemon. Notifications
707 are status messages that may be associated with a data instance.
708 * collectd: Threshold checking has been added to the daemon. This
709 means that you can configure threshold values for each data
710 instance. If this threshold is exceeded a notification will be
712 * collectd: The new `FQDNLookup' option tells the daemon to use the
713 full qualified domain name as the hostname, not just the host part
714 es returned by `gethostname(2)'.
715 * collectd: Support for more than one `TypesDB' file has been added.
716 This is useful when one such file is included in a package but one
717 wants to add custom type definitions.
718 * collectd: The `Include' config option has been expanded to handle
719 entire directories and shell wildcards.
720 * collectdmon: The new `collectdmon' binary detects when collectd
721 terminates and automatically restarts it again.
722 * csv plugin: The CSV plugin is now able to store counter values as a
723 rate, using the `StoreRates' configuration option.
724 * exec plugin: Handling of notifications has been added and the
725 ability to pass arguments to the executed programs has been added.
726 * hddtemp plugin: The new `TranslateDevicename' option lets you
727 disable the translation from device names to major-minor-numbers.
728 * logfile plugin: Handling of notifications has been added.
729 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
730 domain name lookups in this plugin.
731 * perl plugin: Many internal changes added support for handling multiple
732 threads making the plugin reasonably usable inside collectd. The API has
733 been extended to support notifications and export global variables to
734 Perl plugins; callbacks now have to be identified by name rather than a
735 pointer to a subroutine. The plugin is no longer experimental.
736 * uuid plugin: The new UUID plugin sets the hostname to an unique
737 identifier for this host. This is meant for setups where each client
738 may migrate to another physical host, possibly going through one or
739 more name changes in the process. Thanks to Richard Jones from
740 Red Hat's Emerging Technology group for this plugin.
741 * libvirt: The new libvirt plugin uses the `libvirt' library to query
742 CPU, disk and network statistics about guest systems on the same
743 physical server. Thanks to Richard Jones from Red Hat's Emerging
744 Technology group for this plugin.
746 2008-04-22, Version 4.2.7
747 * build system: Improved detection of several libraries, especially if
748 they are in non-standard paths.
749 * build system: Portability fixes: Automatically define "_REENTRANT"
750 if the libc expects it.
751 * collectd: Error and warning messages have been improved.
752 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
754 * apache plugin: Allocate new memory when reading a webpage instead of
755 using a buffer of static size.
756 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
758 * hddtemp plugin: Error and warning messages have been improved.
759 * sensors plugin: Fix sensor collection for some chip types.

763 * sensors plugin: Fix temperature collection with libsensors4.
764 * unixsock plugin: Fix mixed input and output operation on streams.
765 * wireless plugin: Fix reading noise value.
767 2008-03-04, Version 4.2.5
768 * apache plugin: Improved initialization and error messages.
769 * exec plugin: Set supplementary group IDs.
771 + Create separate threads for reading from the socket and parsing
772 and dispatching incoming packets. Versions prior to this may have
773 problems in high-load situations, where the socket receive buffers
774 overflows, resulting in gaps in the data.
775 + Use `memcpy' when constructing/parsing a package to avoid
776 alignment problems on weird architectures, such as Sparc.
777 + Translate doubles to/from the x86 byte representation to ensure
778 cross-platform compatibility.
779 * ping plugin: Correct the handling of the `TTL' setting.
780 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
781 * swap plugin: Reapply a patch for Solaris.
782 * tcpconns plugin: Portability improvements.
784 2008-01-21, Version 4.2.4
785 * unixsock plugin: A bug in the unixsock plugin caused it not to set
786 the permission on the socket as documented in the manpage. Thanks to
787 Evgeny Chukreev for fixing this issue.
788 * collectd: The documentation has been improved.
790 2007-12-28, Version 4.2.3
791 * sensors plugin: Updated the plugin to build and work with version 3
792 of the libsensors library.
794 2007-12-15, Version 4.2.2
795 * nginx plugin: Incorrect comparison of strings lead to a segfault
796 when using the plugin. Thanks to Saulius Grigaliunas for fixing
798 * logfile plugin: The config option `Timestamp' was handled
799 incorrectly and basically always active. Thanks to Luke Heberling
802 2007-11-08, Version 4.2.1
803 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
805 * snmp plugin: Fix a memory leak.
807 2007-10-27, Version 4.2.0
808 * collectd: The new config option `Include' lets you include other
809 configfiles and thus split up your config into smaller parts. This
810 may be especially interesting for the snmp plugin to keep the data
811 definitions separate from the host definitions.
812 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
813 (number of connections, octets and packets for each service and
814 destination). Thanks to Sebastian Harl for this plugin.
815 * memcached plugin: The new `memcached' plugin connects to a memcached
816 daemon process and collects statistics of this distributed caching
817 system. Thanks to Antony Dovgal for contributing this plugin.
818 * nginx plugin: The new `nginx' plugin reads the status page of an
819 nginx daemon and saves the handled connections and requests.
820 * perl plugin: Many changes, including the added `EnableDebugger'
821 config option which lets you debug your Perl plugins more easily.
822 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
823 be more thread-safe otherwise by locking calls to the library.
824 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
825 correct the values returned by SNMP-agents. If a <data> block is
826 defined as `table' the instance is now optional. The sequence number
827 is used as the type-instance in this case. The new `InstancePrefix'
828 option allows to add arbitrary prefixes to the type-instance.
829 * tcpconns plugin: The new `tcpconns' plugin collects the number of
830 certain TCP connections and what state they're in. This can be used
831 to see how many connections your FTP server has to handle or how
832 many outgoing connections your mailserver has open.
834 2008-01-11, Version 4.1.6
835 * unixsock plugin: A bug in the unixsock plugin caused it not to set
836 the permission on the socket as documented in the manpage. Thanks to
837 Evgeny Chukreev for fixing this issue.
838 * collectd: The documentation has been improved.
840 2007-12-27, Version 4.1.5

844 of the libsensors library.
846 2007-11-08, Version 4.1.4
847 * Build system: Improve detection of the rrd library, especially if
848 it's in a non-standard location.
849 * Build system: A bug when parsing the argument for
850 `--with-libnetsnmp' has been fixed.
851 * collectd: Implement `strerror_r' if the libc doesn't provide it.
852 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
853 a deadlock or delay when shutting down the daemon.
854 * snmp plugin: Fix a memory leak.
856 2007-10-24, Version 4.1.3
857 * collectd: A build issue under Solaris has been resolved by renaming
859 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
860 be more thread-safe otherwise by locking calls to the library.
862 2007-09-28, Version 4.1.2
863 * apcups plugin: Fix reporting of the `load percent' data.
864 * wireless plugin: Correct the handling of cards returning signal and
865 noise quality as percentage.
866 * perl plugin: Fix a possible buffer overflow in get_module_name().
867 * build system: Further improve the detection of libraries.
868 * netlink plugin: Build issues under some older versions of the Linux
869 includes (i. e. Debian Sarge) have been fixed.
870 * snmp plugin: Fix a potential segfault when a host times out. Add
871 support for the `timeticks' type.
873 2007-09-12, Version 4.1.1
874 * Build system: The detection of `libnetlink' has been improved.
875 * collectd: The documentation has been fixed in numerous places.
876 * exec plugin: Setting the group under which to run a program has been
878 * collectd: The `sstrerror' function was improved to work correctly
879 with the broken GNU version of `strerror_r'.
880 * collectd: Write an error message to STDERR when loading of a plugin
882 * apcups plugin: Fix the `types' used to submit the values: They still
883 has an `apcups_' prefix which doesn't work anymore.
884 * rrdtool plugin: Create new RRD-files with the `begin' time set to
885 whatever the client thinks is `now'..
887 2007-09-01, Version 4.1.0
888 * Build system: The build system has been changed to automatically
889 disable all plugins, which are missing dependencies. The dependency
890 checking has been removed from the plugins themselves to remove
892 * Flexible interval: The interval of collected data is now sent along
893 with the data itself over the network, so that the interval-settings
894 of server and clients no longer needs to match.
895 * netlink plugin: The new `netlink' plugin connects to the Linux
896 kernel using a netlink socket and uses it to query information about
897 interfaces, qdiscs and classes.
898 * rrdtool plugin: The cache is now dumped to disk in an extra thread
899 to not block data collection.
900 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
901 network devices, such as switches, routers, thermometers, rack
902 monitoring servers, etc. The collectd-snmp(5) manpage documents this
904 * unixsock plugin: Added the `LISTVAL' command.
905 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
906 of music played with xmms.
908 2007-09-28, Version 4.0.9
909 * apcups plugin: Fix reporting of the `load percent' data.
910 * wireless plugin: Correct the handling of cards returning signal and
911 noise quality as percentage.
912 * perl plugin: Fix a possible buffer overflow in get_module_name().
914 2007-09-12, Version 4.0.8
915 * collectd: The `sstrerror' function was improved to work correctly
916 with the broken GNU version of `strerror_r'.
917 * collectd: Write an error message to STDERR when loading of a plugin
919 * apcups plugin: Fix the `types' used to submit the values: They still
920 has an `apcups_' prefix which doesn't work anymore.
921 * rrdtool plugin: Create new RRD-files with the `begin' time set to
922 whatever the client thinks is `now'..
924 2007-08-26, Version 4.0.7
925 * documentation: Some typos have been fixed and some information has
927 * build system: Many fixes for detecting libraries in unusual places,
928 such as on RedHat systems. The affected libraries are `libcurl',
929 `libmysql', and `libupsclient'.
930 * network plugin: Allow the `Port' option to be specified as a number
931 (i. e. without quotes).
932 * nut plugin: A fix allows linking the nut plugin against
933 libupsclient, version >= 2.2.0.
934 * processes plugin: Fix a potential segmentation fault.
936 2007-07-30, Version 4.0.6
937 * sensors plugin: Fix the ignorelist functionality: Only the `type
938 instance' was used to match against the list, but the documentation
939 told otherwise. This release fixes the code, so it complies with the
941 * syslog plugin: Call `openlog' right when the plugin is loaded, so
942 configuration messages will end up in the logging facility.
943 * conrtib/fedora: The contributed specfile for Fedora has been
946 2007-07-05, Version 4.0.5
947 * Portability: More fixes for OpenBSD have been included.
949 2007-06-24, Version 4.0.4
950 * cpu plugin: Fixed the Solaris code.
951 * dns plugin: Fixed a build issue for OpenBSD.
952 * interface plugin: Fixed the Solaris code.
953 * load plugin: Fixed the alternative `/proc' Linux code.
954 * memory plugin: Fixed the Solaris code.
955 * oconfig: Don't require `-lfl' anymore.
957 2007-06-19, Version 4.0.3
958 * cpu plugin: Fix the Darwin / Mac OS X code.
959 * ping plugin: Use the return value of `getpid', not its address.
960 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
961 initialized correctly.
962 * configure: Added `--with-nan-emulation' to aid cross compilation.
964 2007-06-12, Version 4.0.2
965 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
966 they're given in numerically form.
968 2007-06-07, Version 4.0.1
969 * iptables plugin: A bug in the configuration routine has been fixed.
970 Setting a comment in the configfile will no longer cause a
973 2007-06-03, Version 4.0.0
974 * collectd: The plugin-infrastructure has been changed to allow for
975 more types of plugins, namely `write' and `log' plugins.
976 * collectd: The read-function has been changed to read many plugins in
977 parallel, using threads. Thus, plugins generally need to use
978 thread-safe functions from now on.
979 * collectd: The '-t' command line options allows to perform syntax tests
980 of the configuration file and exit immediately.
981 * csv plugin: The new `csv' plugin handles output to `comma separated
983 * rrdtool plugin: The new `rrdtool' plugin handles output to
984 RRD-files. Data can be cached to combine multiple updates into one
985 write to increase IO-performance.
986 * network plugin: The new `network' plugin handles IO via the network.
987 It implements a different, much more extensible protocol which can
988 combine many values in one packet, decreasing the number of UDP-
989 packets being sent. It can read from and send to the network and
990 with the appropriate configuration even forward packets to other
992 * unixsock plugin: The new `unixsock' plugin provides an interface to
993 communicate with the daemon while it is running. Right now the
994 commands `GETVAL' and `PUTVAL' are implemented, but more are to
996 * perl plugin: The new `perl' plugin allows you to write extensions
997 for collectd in the scripting-language Perl.
998 * logfile plugin: The new `logfile' plugin writes logmessages to files

1001 system's syslog daemon.
1002 * entropy plugin: The new `entropy' plugin collects the amount of
1003 entropy currently being available to the system.
1004 * exec plugin: The new `exec' plugin forks child processes and reads
1005 back values provided by the forked processes.
1006 * iptables plugin: The new `iptables' plugin reads counters from
1007 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1009 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1010 to Peter Holik for contributing this plugin.
1011 * nut plugin: The new `nut' plugin connects the upsd of the `network
1012 ups tools' and reads information about the connected UPS.
1013 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1014 connections) field was added by Florent Monbillard.
1015 * collectd-nagios: The new `collectd-nagios' binary queries values
1016 from collectd, parses them and exits according to Nagios-standards.
1017 * manpages: The manpages have been improved a lot.
1019 2007-09-28, Version 3.11.7
1020 * wireless plugin: Correct the handling of cards returning signal and
1021 noise quality as percentage.
1023 2007-08-31, Version 3.11.6
1024 * processes plugin: Fix a potential segmentation fault.
1026 2007-05-29, Version 3.11.5
1027 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1028 * ntpd plugin: Fix a potential buffer overflow.
1029 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1030 were accounted as `zombies'.
1032 2007-04-10, Version 3.11.4
1033 * dns plugin: Change the order of includes to make the plugin compile
1036 2007-03-30, Version 3.11.3
1037 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1038 of the unused `COLLECT_KSTAT'.
1040 2007-02-11, Version 3.11.2
1041 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1042 NULL-pointer may have been passed to `printf' which causes a
1043 segfault with some libcs.
1045 2007-02-10, Version 3.11.1
1046 * df plugin: Some wrong defines have been fixed so the plugin works
1047 under Solaris again.
1048 * dns plugin: The usage of a struct has been fixed to work with
1050 * processes plugin: Some missing defines have been added so the plugin
1051 compiles cleanly under FreeBSD and presumably other UNIXes.
1053 2006-12-22, Version 3.11.0
1054 * collectd: The new command line option `-P' makes it easier for
1055 distributors to change the location of PID-files.
1056 * collectd: The daemon shuts down faster now which makes it easier to
1057 write init.d-scripts for it.
1058 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1059 caused problems every now and then.
1060 * df plugin: New config options allow to ignore certain mountpoints,
1061 filesystem types or devices.
1062 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1063 and interprets it. It collects traffic as well as qtype, opcode and
1065 * email plugin: Sebastian Harl has contributed this plugin which
1066 counts received mails in categories (e. g. ham, spam, virus), spam
1067 score (as given by SpamAssassin) and check types.

1071 processes, that's process and thread count, CPU usage, resident
1072 segment size and pagefaults.
1073 * multimeter plugin: Peter Holik contributed a new plugin which
1074 queries multimeters.
1075 * sensors plugin: Lubos Stanek has put much effort into improving this
1076 plugin, including `extended naming', collection of voltage values
1077 and the possibility to ignore certain values.
1079 2006-12-21, Version 3.10.4
1080 * Max Kellermann has identified a bug in the server routine: When
1081 opening a socket fails the daemon will (re)try opening the socket in
1082 an endless loop, ultimately leading to a `EMFILE' error.
1084 2006-11-04, Version 3.10.3
1085 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1086 ntpd's reply was sent in more than one packet, the buffer size was
1087 calculated incorrectly, resulting in the reading of uninitialized or
1090 2006-11-01, Version 3.10.2
1091 * The sample config file has been improved.
1092 * Errors in the manpages have been corrected.
1093 * The ping-plugin now adds hosts during initialization, not during
1094 startup. This speeds up startup when no network connectivity is
1095 available. Also, the hosts are being added later when the network is
1097 * Improved BSD-support for the df-plugin.
1098 * Fixed syntax errors in the swap-plugin for Mac OS X.
1099 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1101 * Don't disable the mysql-plugin if connecting to the database fails
1102 during initialization. Instead, try again in increasing intervals.
1104 2006-07-19, Version 3.10.1
1105 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1106 the apcups cannot be reached, unconnected sockets will pile up and
1107 eventually lead to `Too many open files' errors.
1109 2006-07-09, Version 3.10.0
1110 * The `disk' plugin has been ported to Darwin.
1111 * The `battery' plugin should work on many Apple computers now.
1112 * The `traffic' plugin can now ignore certain interfaces. Also,
1113 statistics for sent/received packets and errors have been added.

1115 to Anthony Gialluca for contributing this plugin and providing me
1116 with a test environment :)
1117 * A plugin for monitoring an NTP instance and the local clock drift
1120 2006-06-25, Version 3.9.4
1121 * The Solaris code in the `swap' plugin has been changed to reflect
1122 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1124 * The debugging system has been fixed to work with the Sun libc.
1125 * When built without librrd the variable `operating_mode' could be
1126 uninitialized. Thanks to David Elliot for reporting the bug.
1128 2006-06-01, Version 3.9.3
1129 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1130 operating systems also profit from the changes, but I wasn't able to
1132 * Changed the build system to find the netinet-includes under FreeBSD
1133 and therefore successfully build the `liboping' library there.
1135 2006-05-09, Version 3.9.2
1136 * Applied a patch to the `liboping' library. Due to a bug in the
1137 sequence checking the `ping' plugin stopped working after
1138 approximately 7.6 days.
1140 2006-05-09, Version 3.8.5
1141 * Applied a patch to the `liboping' library. Due to a bug in the
1142 sequence checking the `ping' plugin stopped working after
1143 approximately 7.6 days.
1145 2006-04-21, Version 3.9.1
1146 * Build issues with Solaris and possible other architectures have been
1148 * Problems when building the `apache'-plugin without `libcurl' have

1153 * A plugin to monitor the Apache webserver has been added.
1154 <http://httpd.apache.org/>
1155 * A plugin to collect statistics about virtual servers using VServer.
1156 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1158 * A plugin for wireless LAN cards has been added. It monitors signal
1159 strength, link quality and noise ratio..
1160 * A plugin for Apple hardware sensors has been added.
1161 * An option to compile collectd with different `step' and `heartbeat'
1162 settings has been added. The size of RRAs is no longer static but
1163 calculated based on the settings for `step' and `width'.
1164 * The `ping' plugin can now be configured to use a certain TTL.
1165 * A plugin to monitor the hardware sensors of Apple computers has been
1167 * The plugins `cpu', `memory', `processes' and `traffic' have been
1168 ported to Mach/Darwin (Mac OS X).
1169 * The `log mode' has been contributed by Christophe Kalt. It writes
1170 the data into text files rather than RRD files.
1172 2006-04-09, Version 3.8.4
1173 * Applied patch by Vincent Stehlé which improves the disk-name
1174 resolution in the `hddtemp' plugin for Linux systems.
1176 2006-04-02, Version 3.8.3
1177 * Applied a patch by James Byers: The MySQL plugin was not working
1178 with MySQL 5.0.2 or later.
1180 2006-03-14, Version 3.8.2
1181 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1182 the GNU libc, because it points to `/etc/fstab' rather than
1185 2006-03-13, Version 3.8.1
1186 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1187 * Fixes in the debian `postinst' and `init.d' scripts.
1189 2006-03-09, Version 3.8.0
1190 * The `ping' plugin no longer uses `libping' but a self written
1191 library named `liboping'. With this library it's possible to ping
1192 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1194 2006-02-18, Version 3.7.2
1195 * A simple bug in the `battery' plugin has been fixed. It should now
1196 work with ACPI based batteries as well. Thanks to Sebastian for
1198 * Fixing a bug that prevented collectd to be built without librrd.
1199 Thanks to Werner Heuser for reporting it.
1201 2006-02-04, Version 3.7.1
1202 * The new network code has been improved to build with older versions
1204 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1205 to Tommie Gannert for this patch.
1207 2006-01-30, Version 3.7.0
1208 * The `battery' plugin has been added. It collects information about
1210 * The MySQL plugin has been improved: It now writes two more RRD
1211 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1212 * The `cpufreq' plugin now reads another file since the file it did
1213 read so far causes much overhead in the kernel. Also, you need root
1214 to read the old file, but not to read the new one.
1215 * The `hddtemp' plugin can now be configured to connect to another
1216 address and/or port than localhost.
1217 * The `df' plugin now prefers `statvfs' over `statfs'.
1218 * The network code has been rewritten. collectd now supports unicast
1219 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1220 be set in the configfile.
1222 2006-01-24, Version 3.6.2
1223 * Due to a bug in the configfile handling collectd wouldn't start in
1224 client mode. This released fixes this.
1226 2006-01-20, Version 3.6.1
1227 * Due to a bug in `configure.in' all modules and the binary were
1228 linked against `libmysqlclient'. This issue is solved by this
1231 2006-01-17, Version 3.6.0
1232 * A config file has been added. This allows for loading only specific
1234 * A `df' plugin has been added.
1235 * A `mysql' plugin has been added.
1236 * The `ping' plugin doesn't entirely give up hope when a socket error
1237 occurred, but will back of and increase the intervals between tries.
1239 2006-01-21, Version 3.5.2
1240 * Fixed yet another bug in the signal handling.. Stupid typo..
1241 * Improved the ping plugin to not give up on socket errors (backport
1244 2005-12-18, Version 3.5.1
1245 * The PID-file is now deleted correctly when shutting down the daemon.
1246 * SIGINT and SIGTERM are now handled correctly.
1248 2005-12-16, Version 3.5.0 (Revision 326)
1249 * A bug in the `load' module under Solaris has been fixed.
1250 * The `users' module has been contributed by Sebastian Harl. It counts
1251 currently logged in users.
1252 * The CPU module now works under FreeBSD without the use of
1253 `libstatgrab', however SMP support is missing.
1254 * The default directories for the RRD files and the PID file now
1255 depend on the compile time setting of `localstatedir'.
1257 2005-11-15, Version 3.4.0 (Revision 236)
1258 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1259 from gentoo's bugzilla for writing the patch.
1260 * The build dependency for librrd has been removed. Binaries built
1261 without librrd are client-only and will multicast their value as
1262 with the `-c' argument.
1263 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1264 * The newly introduced `-f' switch prevents daemon initialization
1265 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1266 Barcellos for this patch.
1268 2005-11-04, Version 3.3.0 (Revision 216)
1269 * New modules have been added:
1270 - `serial', for monitoring traffic on the serial interfaces
1271 - `nfs', for graphing NFS procedure calls
1272 - `tape', traffic from/to tape devices
1273 * The memory.rrd now accepts more than 4Gig of memory.
1275 2005-10-26, Version 3.2.0 (Revision 200)
1276 * Support for graphing the processes has been added (thanks to Lyonel
1278 * If reading from hddtemp fails collectd will increase the time
1279 between polls up to one day.
1280 * The init.d files have been improved.
1281 * Problems with the spec file have been fixed.
1283 2005-10-16, Version 3.1.0 (Revision 194)
1284 * Added the `setsid' syscall to the startup code.
1285 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1287 2005-09-30, Version 3.0.0 (Revision 184)
1288 * The ability to send/receive data to/from the network (think
1289 multicast) has been added.
1290 * Modules have been split up into shared libraries can be loaded at
1291 runtime. The biggest advantage is that the core program doesn't need
1292 to be linked against an external library.
1293 * A patch by George Kargiotakis has been applied: It fixes the sensors
1294 behaviour then more than one sensor is being queried.
1296 2005-09-16, Version 2.1.0 (Revision 172)
1297 * A module for swap statistics has been added.
1299 2005-09-09, Version 2.0.0 (Revision 135)
1300 * Filenames can no longer be configured at program startup. The only
1301 options as of this version are the directory and ping hosts.
1302 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1303 Soft-IRQ statistics are added to `System'.
1304 * Diskstats now collect read and write bytes, not sectors.
1305 * Ping statistics can now be collected for more than one host. There
1306 is no default any more: If no host is given no host will be pinged.
1307 * A self-written patch for libping has been applied so it builds
1310 2005-09-01, Version 1.8.1 (Revision 123)
1311 * Much improved configure-script: libraries and features may now be
1313 * More detailed warnings/error messages when RRD update fails.
1315 2005-08-29, Version 1.8.0:
1316 * Support for collecting disk statistics under Solaris.
1318 2005-08-25, Version 1.7.0:
1319 * Support for libstatgrab[1] for load, memory usage and network
1320 traffic. CPU- and disk-usage are not (yet) supported, since
1321 libstatgrab returns insufficient information. I will contact the
1323 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1324 aren't necessarily counted linear which is now handled correctly.
1325 [1]: http://www.i-scream.org/libstatgrab/
1327 2005-08-21, Version 1.6.0:
1328 * Basic support for Solaris: System load and cpu-usage can be
1329 collected under Solaris, too. Other stats will follow later.
1330 * Many fixes in the autoconf-script
1331 * Collection/Museum scripts have been added under contrib/museum
1332 * collectd may now be started in unprivileged mode, though ping
1333 statistics will not work.
1335 2005-07-17, Version 1.5.1:
1336 * Diskstats-RRDs now use major/minor for naming. Some systems have
1337 weird strings as disk-names..
1339 2005-07-17, Version 1.5:
1340 * A new module, diskstats, has been added. It collects information
1341 about the disks and partitions.
1343 2005-07-11, Version 1.4.2:
1344 * The meminfo module has been changed to work with more platforms
1345 and/or kernel versions.
1347 2005-07-10, Version 1.4.1: Correct traffic stats
1348 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1349 forgot to correct when I changed that module.
1351 2005-07-09, Version 1.4: More traffic stats
1352 * Traffic is now collected for all interfaces that can be found
1353 * Temperature-statistics are read from lm-sensors if available
1355 2005-07-08, Version 1.3: CPU stats
1356 * Collecting CPU statistics now
1358 2005-07-12, Version 1.2: Using syslog
1359 * collectd is now using the syslog facility to report errors, warnings
1361 * The default directory is now /var/db/collectd
1363 2005-07-10, Version 1.1: Minor changes
1364 * Nothing really useful to say ;)
1366 2005-07-09, Version 1.0: Initial Version
1367 * The following modules are provided:
