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

336 user to use `matches' and `targets' to control value processing.
337 * collectd: The new `-T' command line argument allows more in-depth
338 testing of a configuration. Thanks to Doug MacEachern for the patch.
339 * collectd-nagios: The Nagios integration command has been updated to
340 use libcollectdclient. The `percentage' aggregation function has
341 been added. Thanks to Fabian Linzberger for the patch.

364 them using the same mechanism that's used in the tail plugin.
365 * dbi plugin: This new plugin allows you to connect to a variety of
366 relational databases and use SQL to gather custom statistics from
367 it. It is similar to the already existing PostgreSQL plugin but uses
368 libdbi to communicate with the database(s).
369 * interface plugin: Use the ignorelist framework when selecting /
370 ignoring interfaces. This allows one to use regular expressions to
371 select interfaces, too.

397 been added. Portability fixes.
398 * rrdcached plugin: This new plugin uses the (still in development)
399 RRD accelerator daemon, rrdcached. This daemon works very similar to
400 the original rrdtool plugin of collectd, but adds some more nice
402 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
405 2009-05-09, Version 4.5.4
406 * Build system, various plugins: Many build fixes for FreeBSD,

419 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
421 * rrdtool plugin: Fix a possible race condition: If the network plugin
422 is initialized and dispatches a value before the rrdtool plugin is
423 initialized, the daemon may crash.
424 * memory plugin: Fix a potential problem under Solaris.
426 2009-02-22, Version 4.5.3
427 * build system: The check for libupsclient even when `pkg-config' is

436 code. Thanks to "thated" for reporting this.
438 2009-01-02, Version 4.5.2
439 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
440 file may be in both locations, especially when the database was
441 installed in a non-standard path. Thanks to Dusty Doris for
443 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
444 Solaris, in the configure script automatically.
445 * build system, tcpconns plugin: Check for `kvm_nlist' and
446 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
447 library with similar functions to the BSD variant, but doesn't
448 provide these necessary functions.
449 * collectd.conf(5): Various fixes and clarifications.
450 * collectd: Remove a GNUism (unnamed unions), thus improving
452 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
453 This solves portability problems, especially for Solaris.
454 * dns plugin: Fix a portability problem with NetBSD.
455 * filecount plugin: Fix an off-by-one error. This error may cause a
457 * network plugin: Fix the handling of `type' in the network protocol.
458 Due to a programming mistake, only 4 or 8 bytes would be copied to a
459 much larger buffer. This caused the `type' to be transferred much
460 more often than necessary. In some cases, e. g. the `cpu' and
461 `cpufreq' plugins being used at the same time, data may be corrupted
462 in those files. Thanks to Bruno Prémont for debugging and reporting
464 * processes plugin: Fix a possible segmentation fault when specifying
465 invalid configuration options.
466 * unixsock plugin: Make sure the initialization function is run only
467 once. This resolves a file descriptor leak under systems which run
468 the initialization more than once, such as Solaris.
470 2008-10-16, Version 4.5.1
471 * build system: Change `--enable-<plugin>' to abort with an error if
472 dependencies are not met. Thanks to Bruno Prémont for the patch.
473 Also, the poisoning of various string functions has been restricted
475 * collectd: Fix a memory leak in the global value cache. With every
476 *missing* value a couple of bytes would be leaked. Another memory
477 leak in the configuration handling code has been fixed. Thanks to
478 Niraj Tolia for reporting these issues.
479 * collectd: Fix an off-by-one error in the ignorelist functionality.
480 When using regular expressions, the last character would be missing,
481 possibly matching differently from what one would expect.
482 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
484 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
485 Linzberger for reporting the bug.
486 * iptables plugin: Fix an off-by-one error. If a string was just one
487 character too long, it was truncated instead of reporting an error.
488 * network plugin: Fix a memory leak in the configuration handling
489 code. Thanks to Niraj Tolia for reporting this issue.
490 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
491 * postgresql plugin: Don't reopen connection during reinitialization.
492 This fixes a bug under Solaris and potentially other platforms.
493 Missing calls to `PQclear' have been added, too. This fixes memory
494 leaks. Thanks to ``Admin'' for reporting these bugs.
495 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
497 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
498 problems with some `libc's. Thanks to Matthias Lay for reporting the
501 2008-09-04, Version 4.5.0
502 * collectd: Added the ability to flush certain identifiers.
503 * collectd: The concept of `notification meta data' has been
505 * filecount plugin: The new filecount plugin counts the number of
506 files in a directory and its subdirectories.
507 * ipmi plugin: Sensor names have been changed to ensure unique names.
508 Notifications upon added and removed sensors can now be generated.
509 * notify_desktop plugin: This new plugin sends notifications to the
510 X desktop using the structure defined in the `Desktop Notification
512 * notify_email plugin: This new plugin sends out notifications via
513 email, using the `esmtp' library.
514 * onewire plugin: The new experimental(!) onewire plugin reads values,
515 such as temperatures, from sensors connected to the computer via the
517 * perl plugin: Improved synchronized access to internal data structures
518 and fixed a possible dead-lock.
519 * perl plugin: Added the ability to flush certain identifiers and marked
520 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
522 * perl plugin: Added the ability to configure Perl plugins.
523 * postgresql plugin: The new postgresql plugin collects statistics
524 about or from a PostgreSQL database.
525 * processes plugin: The `ProcessMatch' option has been added.
526 * rrdtool plugin: Implement throttling of the `update queue' to lessen
528 * tcpconns plugin: This plugin has been ported to OpenBSD.
529 * thermal plugin: The new thermal plugin collects system temperatures
530 using Linux ACPI thermal zone data.
532 2009-01-02, Version 4.4.5
533 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
534 file may be in both locations, especially when the database was
535 installed in a non-standard path. Thanks to Dusty Doris for
537 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
538 Solaris, in the configure script automatically.
539 * collectd.conf(5): Various fixes and clarifications.
540 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
541 portability problems, especially for Solaris.
542 * dns plugin: Fix a portability problem with NetBSD.
543 * network plugin: Fix the handling of `type' in the network protocol.
544 Due to a programming mistake, only 4 or 8 bytes would be copied to a
545 much larger buffer. This caused the `type' to be transferred much
546 more often than necessary. In some cases, e. g. the `cpu' and
547 `cpufreq' plugins being used at the same time, data may be corrupted
548 in those files. Thanks to Bruno Prémont for debugging and reporting
550 * unixsock plugin: Make sure the initialization function is run only
551 once. This resolves a file descriptor leak under systems which run
552 the initialization more than once, such as Solaris.
554 2008-10-16, Version 4.4.4
555 * build system: Change `--enable-<plugin>' to abort with an error if
556 dependencies are not met. Thanks to Bruno Prémont for the patch.
557 Also, the poisoning of various string functions has been restricted
559 * collectd: Fix a memory leak in the global value cache. With every
560 *missing* value a couple of bytes would be leaked. Another memory
561 leak in the configuration handling code has been fixed. Thanks to
562 Niraj Tolia for reporting these issues.
563 * collectd: Fix an off-by-one error in the ignorelist functionality.
564 When using regular expressions, the last character would be missing,
565 possibly matching differently from what one would expect.
566 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
568 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
569 Linzberger for reporting the bug.
570 * network plugin: Fix a memory leak in the configuration handling
571 code. Thanks to Niraj Tolia for reporting this issue.
572 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
573 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
574 problems with some `libc's. Thanks to Matthias Lay for reporting the
577 2008-09-01, Version 4.4.3
578 * collectd: Fix a memory leak in the threshold checking code.
579 * memcached plugin: Fix a too short timeout and a related file
581 * memory plugin: A typo in the libstatgrab code has been fixed.
582 * snmp plugin: Fix a possible memory leak.
584 2008-07-15, Version 4.4.2
585 * build system: Use pkg-config to detect the upsclient library.
586 * collectd: Try even harder to determine the endianess of the
587 architecture collectd is being built on.
588 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
590 * dns plugin: Fix compilation errors with BIND versions 19991001
592 * network plugin: Bugfix in the init routine: The init function
593 cleared a buffer regardless of its contents. This could lead to lost
594 values under Solaris.
595 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
596 * vserver plugin: Remove usage of the thread-unsafe `readdir'
598 * wireless plugin: Work around incorrect noise and power values
599 returned by some broken drivers.
601 2008-06-03, Version 4.4.1
602 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
603 to kyrone for reporting this.
604 * collectd: Fixed min/max output in notifications generated by
606 * collectd-nagios: Fix the protocol used to communicate with the
608 * perl plugin: Fail noisily, but don't shutdown the daemon, if
609 initialization has errors. An issue with Perl 5.10 has been fixed.
610 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
611 René Rebe and Siegmund Gorr for reporting this.
613 2008-05-06, Version 4.4.0
614 * collectd: Internal code cleanups.
615 * collectd: Added support for a `Flush' command in the unixsock and
616 exec plugins. This command can be used to force a plugin (or all) to
617 flush its values to disk.
618 * collectd: Thresholds can now be configured to apply to one data
619 source only, making it possible to configure different thresholds
620 for each data source.
621 * apache, nginx plugins: Added the possibility to disable host and/or
623 * ascent plugin: The new ascent plugin reads and parses the statistics
624 page of an Ascent server.
625 * cpu plugin: Support for the statgrab library has been added.
626 * disk plugin: The possibility to ignore certain disks or collect only
627 specific disks has been added.
628 * disk plugin: Support for the statgrab library has been added.
629 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
630 sensor values via IPMI, the intelligent platform management
632 * iptables plugin: The iptc library that is used by the iptables
633 plugin has been added to the distribution, because it is not
634 provided by all distributions and removed from at least one.
635 * powerdns plugin: The new powerdns plugin reads statistics from an
636 authoritative or a recursing PowerDNS name server.
637 * rrdtool plugin: The size of the files generated with the default
638 configuration has been decreased.
639 * tail plugin: The new tail plugin can be used to gather statistics by
640 continuously reading from log files.
641 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
642 TeamSpeak2 server and collects statistics about the number of users
643 and number of channels.
644 * users plugin: Support for the statgrab library has been added.
645 * vmem plugin: The new vmem plugin collects very detailed statistics
646 about the virtual memory subsystem of Linux.
648 2008-08-30, Version 4.3.4
649 * Build system: Improved detection of and linking with the statgrab
651 * collectd: Portability fixes, especially to determine endianess more
653 * Various plugins: Fix format strings.
654 * disk plugin: A fix for giving disks under Linux 2.4 the right names
655 again has been applied.
656 * memcached plugin: Fix a too short timeout and a related file
658 * memory plugin: A typo in the libstatgrab code has been fixed.
659 * network plugin: A fix in the initialization function solves problems
661 * nginx plugin: A thread-unsafe function has been replaced.
662 * vserver plugin: A thread-unsafe function has been replaced.
663 * wireless plugin: A work-around for broken wireless drivers has been
666 2008-04-22, Version 4.3.3
667 * build system: Improved detection of several libraries, especially if
668 they are in non-standard paths.
669 * build system: Portability fixes: Automatically define "_REENTRANT"
670 if the libc expects it.
671 * collectd: Error and warning messages have been improved.
672 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
674 * apache plugin: Allocate new memory when reading a webpage instead of
675 using a buffer of static size.
676 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
678 * hddtemp plugin: Error and warning messages have been improved.
679 * sensors plugin: Fix sensor collection for some chip types.
681 2008-03-29, Version 4.3.2
682 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
683 `Persist' threshold options.
684 * collectd: Fix handling of missing values in the global value cache.
685 * collectd: Improved error messages when parsing the configuration.
686 * sensors plugin: Fix temperature collection with libsensors4.
687 * unixsock plugin: Fix mixed input and output operation on streams.
688 * wireless plugin: Fix reading noise value.
690 2008-03-05, Version 4.3.1
691 * exec plugin: Set supplementary group IDs.
693 + Use `memcpy' when constructing/parsing a package to avoid
694 alignment problems on weird architectures, such as Sparc.
695 + Translate doubles to/from the x86 byte representation to ensure
696 cross-platform compatibility.
697 * ping plugin: Correct the handling of the `TTL' setting.
698 * swap plugin: Reapply a patch for Solaris.
699 * tcpconns plugin: Portability improvements.
701 2008-02-18, Version 4.3.0
702 * collectd: Notifications have been added to the daemon. Notifications
703 are status messages that may be associated with a data instance.
704 * collectd: Threshold checking has been added to the daemon. This
705 means that you can configure threshold values for each data
706 instance. If this threshold is exceeded a notification will be
708 * collectd: The new `FQDNLookup' option tells the daemon to use the
709 full qualified domain name as the hostname, not just the host part
710 es returned by `gethostname(2)'.
711 * collectd: Support for more than one `TypesDB' file has been added.
712 This is useful when one such file is included in a package but one
713 wants to add custom type definitions.
714 * collectd: The `Include' config option has been expanded to handle
715 entire directories and shell wildcards.
716 * collectdmon: The new `collectdmon' binary detects when collectd
717 terminates and automatically restarts it again.
718 * csv plugin: The CSV plugin is now able to store counter values as a
719 rate, using the `StoreRates' configuration option.
720 * exec plugin: Handling of notifications has been added and the
721 ability to pass arguments to the executed programs has been added.
722 * hddtemp plugin: The new `TranslateDevicename' option lets you
723 disable the translation from device names to major-minor-numbers.
724 * logfile plugin: Handling of notifications has been added.
725 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
726 domain name lookups in this plugin.
727 * perl plugin: Many internal changes added support for handling multiple
728 threads making the plugin reasonably usable inside collectd. The API has
729 been extended to support notifications and export global variables to
730 Perl plugins; callbacks now have to be identified by name rather than a
731 pointer to a subroutine. The plugin is no longer experimental.
732 * uuid plugin: The new UUID plugin sets the hostname to an unique
733 identifier for this host. This is meant for setups where each client
734 may migrate to another physical host, possibly going through one or
735 more name changes in the process. Thanks to Richard Jones from
736 Red Hat's Emerging Technology group for this plugin.
737 * libvirt: The new libvirt plugin uses the `libvirt' library to query
738 CPU, disk and network statistics about guest systems on the same
739 physical server. Thanks to Richard Jones from Red Hat's Emerging
740 Technology group for this plugin.
742 2008-04-22, Version 4.2.7
743 * build system: Improved detection of several libraries, especially if
744 they are in non-standard paths.
745 * build system: Portability fixes: Automatically define "_REENTRANT"
746 if the libc expects it.
747 * collectd: Error and warning messages have been improved.
748 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
750 * apache plugin: Allocate new memory when reading a webpage instead of
751 using a buffer of static size.
752 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
754 * hddtemp plugin: Error and warning messages have been improved.
755 * sensors plugin: Fix sensor collection for some chip types.

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

840 of the libsensors library.
842 2007-11-08, Version 4.1.4
843 * Build system: Improve detection of the rrd library, especially if
844 it's in a non-standard location.
845 * Build system: A bug when parsing the argument for
846 `--with-libnetsnmp' has been fixed.
847 * collectd: Implement `strerror_r' if the libc doesn't provide it.
848 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
849 a deadlock or delay when shutting down the daemon.
850 * snmp plugin: Fix a memory leak.
852 2007-10-24, Version 4.1.3
853 * collectd: A build issue under Solaris has been resolved by renaming
855 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
856 be more thread-safe otherwise by locking calls to the library.
858 2007-09-28, Version 4.1.2
859 * apcups plugin: Fix reporting of the `load percent' data.
860 * wireless plugin: Correct the handling of cards returning signal and
861 noise quality as percentage.
862 * perl plugin: Fix a possible buffer overflow in get_module_name().
863 * build system: Further improve the detection of libraries.
864 * netlink plugin: Build issues under some older versions of the Linux
865 includes (i. e. Debian Sarge) have been fixed.
866 * snmp plugin: Fix a potential segfault when a host times out. Add
867 support for the `timeticks' type.
869 2007-09-12, Version 4.1.1
870 * Build system: The detection of `libnetlink' has been improved.
871 * collectd: The documentation has been fixed in numerous places.
872 * exec plugin: Setting the group under which to run a program has been
874 * collectd: The `sstrerror' function was improved to work correctly
875 with the broken GNU version of `strerror_r'.
876 * collectd: Write an error message to STDERR when loading of a plugin
878 * apcups plugin: Fix the `types' used to submit the values: They still
879 has an `apcups_' prefix which doesn't work anymore.
880 * rrdtool plugin: Create new RRD-files with the `begin' time set to
881 whatever the client thinks is `now'..
883 2007-09-01, Version 4.1.0
884 * Build system: The build system has been changed to automatically
885 disable all plugins, which are missing dependencies. The dependency
886 checking has been removed from the plugins themselves to remove
888 * Flexible interval: The interval of collected data is now sent along
889 with the data itself over the network, so that the interval-settings
890 of server and clients no longer needs to match.
891 * netlink plugin: The new `netlink' plugin connects to the Linux
892 kernel using a netlink socket and uses it to query information about
893 interfaces, qdiscs and classes.
894 * rrdtool plugin: The cache is now dumped to disk in an extra thread
895 to not block data collection.
896 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
897 network devices, such as switches, routers, thermometers, rack
898 monitoring servers, etc. The collectd-snmp(5) manpage documents this
900 * unixsock plugin: Added the `LISTVAL' command.
901 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
902 of music played with xmms.
904 2007-09-28, Version 4.0.9
905 * apcups plugin: Fix reporting of the `load percent' data.
906 * wireless plugin: Correct the handling of cards returning signal and
907 noise quality as percentage.
908 * perl plugin: Fix a possible buffer overflow in get_module_name().
910 2007-09-12, Version 4.0.8
911 * collectd: The `sstrerror' function was improved to work correctly
912 with the broken GNU version of `strerror_r'.
913 * collectd: Write an error message to STDERR when loading of a plugin
915 * apcups plugin: Fix the `types' used to submit the values: They still
916 has an `apcups_' prefix which doesn't work anymore.
917 * rrdtool plugin: Create new RRD-files with the `begin' time set to
918 whatever the client thinks is `now'..
920 2007-08-26, Version 4.0.7
921 * documentation: Some typos have been fixed and some information has
923 * build system: Many fixes for detecting libraries in unusual places,
924 such as on RedHat systems. The affected libraries are `libcurl',
925 `libmysql', and `libupsclient'.
926 * network plugin: Allow the `Port' option to be specified as a number
927 (i. e. without quotes).
928 * nut plugin: A fix allows linking the nut plugin against
929 libupsclient, version >= 2.2.0.
930 * processes plugin: Fix a potential segmentation fault.
932 2007-07-30, Version 4.0.6
933 * sensors plugin: Fix the ignorelist functionality: Only the `type
934 instance' was used to match against the list, but the documentation
935 told otherwise. This release fixes the code, so it complies with the
937 * syslog plugin: Call `openlog' right when the plugin is loaded, so
938 configuration messages will end up in the logging facility.
939 * conrtib/fedora: The contributed specfile for Fedora has been
942 2007-07-05, Version 4.0.5
943 * Portability: More fixes for OpenBSD have been included.
945 2007-06-24, Version 4.0.4
946 * cpu plugin: Fixed the Solaris code.
947 * dns plugin: Fixed a build issue for OpenBSD.
948 * interface plugin: Fixed the Solaris code.
949 * load plugin: Fixed the alternative `/proc' Linux code.
950 * memory plugin: Fixed the Solaris code.
951 * oconfig: Don't require `-lfl' anymore.
953 2007-06-19, Version 4.0.3
954 * cpu plugin: Fix the Darwin / Mac OS X code.
955 * ping plugin: Use the return value of `getpid', not its address.
956 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
957 initialized correctly.
958 * configure: Added `--with-nan-emulation' to aid cross compilation.
960 2007-06-12, Version 4.0.2
961 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
962 they're given in numerically form.
964 2007-06-07, Version 4.0.1
965 * iptables plugin: A bug in the configuration routine has been fixed.
966 Setting a comment in the configfile will no longer cause a
969 2007-06-03, Version 4.0.0
970 * collectd: The plugin-infrastructure has been changed to allow for
971 more types of plugins, namely `write' and `log' plugins.
972 * collectd: The read-function has been changed to read many plugins in
973 parallel, using threads. Thus, plugins generally need to use
974 thread-safe functions from now on.
975 * collectd: The '-t' command line options allows to perform syntax tests
976 of the configuration file and exit immediately.
977 * csv plugin: The new `csv' plugin handles output to `comma separated
979 * rrdtool plugin: The new `rrdtool' plugin handles output to
980 RRD-files. Data can be cached to combine multiple updates into one
981 write to increase IO-performance.
982 * network plugin: The new `network' plugin handles IO via the network.
983 It implements a different, much more extensible protocol which can
984 combine many values in one packet, decreasing the number of UDP-
985 packets being sent. It can read from and send to the network and
986 with the appropriate configuration even forward packets to other
988 * unixsock plugin: The new `unixsock' plugin provides an interface to
989 communicate with the daemon while it is running. Right now the
990 commands `GETVAL' and `PUTVAL' are implemented, but more are to
992 * perl plugin: The new `perl' plugin allows you to write extensions
993 for collectd in the scripting-language Perl.
994 * logfile plugin: The new `logfile' plugin writes logmessages to files
996 * syslog plugin: The new `syslog' plugin sends logmessages to the
997 system's syslog daemon.
998 * entropy plugin: The new `entropy' plugin collects the amount of
999 entropy currently being available to the system.
1000 * exec plugin: The new `exec' plugin forks child processes and reads
1001 back values provided by the forked processes.
1002 * iptables plugin: The new `iptables' plugin reads counters from
1003 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1005 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1006 to Peter Holik for contributing this plugin.
1007 * nut plugin: The new `nut' plugin connects the upsd of the `network
1008 ups tools' and reads information about the connected UPS.
1009 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1010 connections) field was added by Florent Monbillard.
1011 * collectd-nagios: The new `collectd-nagios' binary queries values
1012 from collectd, parses them and exits according to Nagios-standards.
1013 * manpages: The manpages have been improved a lot.
1015 2007-09-28, Version 3.11.7
1016 * wireless plugin: Correct the handling of cards returning signal and
1017 noise quality as percentage.
1019 2007-08-31, Version 3.11.6
1020 * processes plugin: Fix a potential segmentation fault.
1022 2007-05-29, Version 3.11.5
1023 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1024 * ntpd plugin: Fix a potential buffer overflow.
1025 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1026 were accounted as `zombies'.
1028 2007-04-10, Version 3.11.4
1029 * dns plugin: Change the order of includes to make the plugin compile
1032 2007-03-30, Version 3.11.3
1033 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1034 of the unused `COLLECT_KSTAT'.
1036 2007-02-11, Version 3.11.2
1037 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1038 NULL-pointer may have been passed to `printf' which causes a
1039 segfault with some libcs.
1041 2007-02-10, Version 3.11.1
1042 * df plugin: Some wrong defines have been fixed so the plugin works
1043 under Solaris again.
1044 * dns plugin: The usage of a struct has been fixed to work with
1046 * processes plugin: Some missing defines have been added so the plugin
1047 compiles cleanly under FreeBSD and presumably other UNIXes.
1049 2006-12-22, Version 3.11.0
1050 * collectd: The new command line option `-P' makes it easier for
1051 distributors to change the location of PID-files.
1052 * collectd: The daemon shuts down faster now which makes it easier to
1053 write init.d-scripts for it.
1054 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1055 caused problems every now and then.
1056 * df plugin: New config options allow to ignore certain mountpoints,
1057 filesystem types or devices.
1058 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1059 and interprets it. It collects traffic as well as qtype, opcode and
1061 * email plugin: Sebastian Harl has contributed this plugin which
1062 counts received mails in categories (e. g. ham, spam, virus), spam
1063 score (as given by SpamAssassin) and check types.
1064 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1065 uses `mbmon' to gather information from sensors on the motherboard.
1066 * processes plugin: Collect detailed statistics for configured
1067 processes, that's process and thread count, CPU usage, resident
1068 segment size and pagefaults.
1069 * multimeter plugin: Peter Holik contributed a new plugin which
1070 queries multimeters.
1071 * sensors plugin: Lubos Stanek has put much effort into improving this
1072 plugin, including `extended naming', collection of voltage values
1073 and the possibility to ignore certain values.
1075 2006-12-21, Version 3.10.4
1076 * Max Kellermann has identified a bug in the server routine: When
1077 opening a socket fails the daemon will (re)try opening the socket in
1078 an endless loop, ultimately leading to a `EMFILE' error.
1080 2006-11-04, Version 3.10.3
1081 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1082 ntpd's reply was sent in more than one packet, the buffer size was
1083 calculated incorrectly, resulting in the reading of uninitialized or
1086 2006-11-01, Version 3.10.2
1087 * The sample config file has been improved.
1088 * Errors in the manpages have been corrected.
1089 * The ping-plugin now adds hosts during initialization, not during
1090 startup. This speeds up startup when no network connectivity is
1091 available. Also, the hosts are being added later when the network is
1093 * Improved BSD-support for the df-plugin.
1094 * Fixed syntax errors in the swap-plugin for Mac OS X.
1095 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1097 * Don't disable the mysql-plugin if connecting to the database fails
1098 during initialization. Instead, try again in increasing intervals.
1100 2006-07-19, Version 3.10.1
1101 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1102 the apcups cannot be reached, unconnected sockets will pile up and
1103 eventually lead to `Too many open files' errors.
1105 2006-07-09, Version 3.10.0
1106 * The `disk' plugin has been ported to Darwin.
1107 * The `battery' plugin should work on many Apple computers now.
1108 * The `traffic' plugin can now ignore certain interfaces. Also,
1109 statistics for sent/received packets and errors have been added.

1111 to Anthony Gialluca for contributing this plugin and providing me
1112 with a test environment :)
1113 * A plugin for monitoring an NTP instance and the local clock drift
1116 2006-06-25, Version 3.9.4
1117 * The Solaris code in the `swap' plugin has been changed to reflect
1118 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1120 * The debugging system has been fixed to work with the Sun libc.
1121 * When built without librrd the variable `operating_mode' could be
1122 uninitialized. Thanks to David Elliot for reporting the bug.
1124 2006-06-01, Version 3.9.3
1125 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1126 operating systems also profit from the changes, but I wasn't able to
1128 * Changed the build system to find the netinet-includes under FreeBSD
1129 and therefore successfully build the `liboping' library there.
1131 2006-05-09, Version 3.9.2
1132 * Applied a patch to the `liboping' library. Due to a bug in the
1133 sequence checking the `ping' plugin stopped working after
1134 approximately 7.6 days.
1136 2006-05-09, Version 3.8.5
1137 * Applied a patch to the `liboping' library. Due to a bug in the
1138 sequence checking the `ping' plugin stopped working after
1139 approximately 7.6 days.
1141 2006-04-21, Version 3.9.1
1142 * Build issues with Solaris and possible other architectures have been
1144 * Problems when building the `apache'-plugin without `libcurl' have
1146 * A bug in the `ping' plugin has been fixed. Sorry folks.
1148 2006-04-02, Version 3.9.0
1149 * A plugin to monitor the Apache webserver has been added.
1150 <http://httpd.apache.org/>
1151 * A plugin to collect statistics about virtual servers using VServer.
1152 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1154 * A plugin for wireless LAN cards has been added. It monitors signal
1155 strength, link quality and noise ratio..
1156 * A plugin for Apple hardware sensors has been added.
1157 * An option to compile collectd with different `step' and `heartbeat'
1158 settings has been added. The size of RRAs is no longer static but
1159 calculated based on the settings for `step' and `width'.
1160 * The `ping' plugin can now be configured to use a certain TTL.
1161 * A plugin to monitor the hardware sensors of Apple computers has been
1163 * The plugins `cpu', `memory', `processes' and `traffic' have been
1164 ported to Mach/Darwin (Mac OS X).
1165 * The `log mode' has been contributed by Christophe Kalt. It writes
1166 the data into text files rather than RRD files.
1168 2006-04-09, Version 3.8.4
1169 * Applied patch by Vincent Stehlé which improves the disk-name
1170 resolution in the `hddtemp' plugin for Linux systems.
1172 2006-04-02, Version 3.8.3
1173 * Applied a patch by James Byers: The MySQL plugin was not working
1174 with MySQL 5.0.2 or later.
1176 2006-03-14, Version 3.8.2
1177 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1178 the GNU libc, because it points to `/etc/fstab' rather than
1181 2006-03-13, Version 3.8.1
1182 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1183 * Fixes in the debian `postinst' and `init.d' scripts.
1185 2006-03-09, Version 3.8.0
1186 * The `ping' plugin no longer uses `libping' but a self written
1187 library named `liboping'. With this library it's possible to ping
1188 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1190 2006-02-18, Version 3.7.2
1191 * A simple bug in the `battery' plugin has been fixed. It should now
1192 work with ACPI based batteries as well. Thanks to Sebastian for
1194 * Fixing a bug that prevented collectd to be built without librrd.
1195 Thanks to Werner Heuser for reporting it.
1197 2006-02-04, Version 3.7.1
1198 * The new network code has been improved to build with older versions
1200 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1201 to Tommie Gannert for this patch.
1203 2006-01-30, Version 3.7.0
1204 * The `battery' plugin has been added. It collects information about
1206 * The MySQL plugin has been improved: It now writes two more RRD
1207 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1208 * The `cpufreq' plugin now reads another file since the file it did
1209 read so far causes much overhead in the kernel. Also, you need root
1210 to read the old file, but not to read the new one.
1211 * The `hddtemp' plugin can now be configured to connect to another
1212 address and/or port than localhost.
1213 * The `df' plugin now prefers `statvfs' over `statfs'.
1214 * The network code has been rewritten. collectd now supports unicast
1215 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1216 be set in the configfile.
1218 2006-01-24, Version 3.6.2
1219 * Due to a bug in the configfile handling collectd wouldn't start in
1220 client mode. This released fixes this.
1222 2006-01-20, Version 3.6.1
1223 * Due to a bug in `configure.in' all modules and the binary were
1224 linked against `libmysqlclient'. This issue is solved by this
1227 2006-01-17, Version 3.6.0
1228 * A config file has been added. This allows for loading only specific
1230 * A `df' plugin has been added.
1231 * A `mysql' plugin has been added.
1232 * The `ping' plugin doesn't entirely give up hope when a socket error
1233 occurred, but will back of and increase the intervals between tries.
1235 2006-01-21, Version 3.5.2
1236 * Fixed yet another bug in the signal handling.. Stupid typo..
1237 * Improved the ping plugin to not give up on socket errors (backport
1240 2005-12-18, Version 3.5.1
1241 * The PID-file is now deleted correctly when shutting down the daemon.
1242 * SIGINT and SIGTERM are now handled correctly.
1244 2005-12-16, Version 3.5.0 (Revision 326)
1245 * A bug in the `load' module under Solaris has been fixed.
1246 * The `users' module has been contributed by Sebastian Harl. It counts
1247 currently logged in users.
1248 * The CPU module now works under FreeBSD without the use of
1249 `libstatgrab', however SMP support is missing.
1250 * The default directories for the RRD files and the PID file now
1251 depend on the compile time setting of `localstatedir'.
1253 2005-11-15, Version 3.4.0 (Revision 236)
1254 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1255 from gentoo's bugzilla for writing the patch.
1256 * The build dependency for librrd has been removed. Binaries built
1257 without librrd are client-only and will multicast their value as
1258 with the `-c' argument.
1259 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1260 * The newly introduced `-f' switch prevents daemon initialization
1261 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1262 Barcellos for this patch.
1264 2005-11-04, Version 3.3.0 (Revision 216)
1265 * New modules have been added:
1266 - `serial', for monitoring traffic on the serial interfaces
1267 - `nfs', for graphing NFS procedure calls
1268 - `tape', traffic from/to tape devices
1269 * The memory.rrd now accepts more than 4Gig of memory.
1271 2005-10-26, Version 3.2.0 (Revision 200)
1272 * Support for graphing the processes has been added (thanks to Lyonel
1274 * If reading from hddtemp fails collectd will increase the time
1275 between polls up to one day.
1276 * The init.d files have been improved.
1277 * Problems with the spec file have been fixed.
1279 2005-10-16, Version 3.1.0 (Revision 194)
1280 * Added the `setsid' syscall to the startup code.
1281 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1283 2005-09-30, Version 3.0.0 (Revision 184)
1284 * The ability to send/receive data to/from the network (think
1285 multicast) has been added.
1286 * Modules have been split up into shared libraries can be loaded at
1287 runtime. The biggest advantage is that the core program doesn't need
1288 to be linked against an external library.
1289 * A patch by George Kargiotakis has been applied: It fixes the sensors
1290 behaviour then more than one sensor is being queried.
1292 2005-09-16, Version 2.1.0 (Revision 172)
1293 * A module for swap statistics has been added.
1295 2005-09-09, Version 2.0.0 (Revision 135)
1296 * Filenames can no longer be configured at program startup. The only
1297 options as of this version are the directory and ping hosts.
1298 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1299 Soft-IRQ statistics are added to `System'.
1300 * Diskstats now collect read and write bytes, not sectors.
1301 * Ping statistics can now be collected for more than one host. There
1302 is no default any more: If no host is given no host will be pinged.
1303 * A self-written patch for libping has been applied so it builds
1306 2005-09-01, Version 1.8.1 (Revision 123)
1307 * Much improved configure-script: libraries and features may now be
1309 * More detailed warnings/error messages when RRD update fails.
1311 2005-08-29, Version 1.8.0:
1312 * Support for collecting disk statistics under Solaris.
1314 2005-08-25, Version 1.7.0:
1315 * Support for libstatgrab[1] for load, memory usage and network
1316 traffic. CPU- and disk-usage are not (yet) supported, since
1317 libstatgrab returns insufficient information. I will contact the
1319 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1320 aren't necessarily counted linear which is now handled correctly.
1321 [1]: http://www.i-scream.org/libstatgrab/
1323 2005-08-21, Version 1.6.0:
1324 * Basic support for Solaris: System load and cpu-usage can be
1325 collected under Solaris, too. Other stats will follow later.
1326 * Many fixes in the autoconf-script
1327 * Collection/Museum scripts have been added under contrib/museum
1328 * collectd may now be started in unprivileged mode, though ping
1329 statistics will not work.
1331 2005-07-17, Version 1.5.1:
1332 * Diskstats-RRDs now use major/minor for naming. Some systems have
1333 weird strings as disk-names..
1335 2005-07-17, Version 1.5:
1336 * A new module, diskstats, has been added. It collects information
1337 about the disks and partitions.
1339 2005-07-11, Version 1.4.2:
1340 * The meminfo module has been changed to work with more platforms
1341 and/or kernel versions.
1343 2005-07-10, Version 1.4.1: Correct traffic stats
1344 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1345 forgot to correct when I changed that module.
1347 2005-07-09, Version 1.4: More traffic stats
1348 * Traffic is now collected for all interfaces that can be found
1349 * Temperature-statistics are read from lm-sensors if available
1351 2005-07-08, Version 1.3: CPU stats
1352 * Collecting CPU statistics now
1354 2005-07-12, Version 1.2: Using syslog
1355 * collectd is now using the syslog facility to report errors, warnings
1357 * The default directory is now /var/db/collectd
1359 2005-07-10, Version 1.1: Minor changes
1360 * Nothing really useful to say ;)
1362 2005-07-09, Version 1.0: Initial Version
1363 * The following modules are provided:
