491 * regex match: Match values by their identifies using regular
493 * timediff match: Match for values with an invalid timestamp.
494 * value match: Select values by their data sources' values.
495 * notification target: Create and dispatch a notification.
496 * replace target: Replace parts of an identifier using regular
498 * set target: Set (overwrite) entire parts of an identifier.
499 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
500 statistics, allowing very detailed name server statistics. Thanks to
501 Bruno Prémont for this plugin.
502 * cpu plugin: Report `interrupt' separately when using
503 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
504 example for native OpenBSD support, has been added. Thanks to Simon
505 Kuhnle for the patch.
506 * csv plugin: Make it possible to write values to STDOUT instead of
507 files. This is meant for testing purposes mostly. The output written
508 to STDOUT is compatible with the exec plugin. Thanks to Doug
509 MacEachern for the patch.
510 * curl plugin: This new plugin can be used to read web pages and parse
511 them using the same mechanism that's used in the tail plugin.
512 * dbi plugin: This new plugin allows you to connect to a variety of
513 relational databases and use SQL to gather custom statistics from
514 it. It is similar to the already existing PostgreSQL plugin but uses
515 libdbi to communicate with the database(s).
516 * interface plugin: Use the ignorelist framework when selecting /
517 ignoring interfaces. This allows one to use regular expressions to
518 select interfaces, too.
519 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
520 Thanks to Bruno Prémont for this patch.
521 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
523 * mysql plugin: Allow connecting to a database via the UNIX domain
524 socket, too. Thanks to Mirko Buffoni for the patch.
525 * network plugin: Further performance improvements for the receive
526 code. This hopefully will help very large setups.
527 * openvpn plugin: This new plugin collects statistics provided by the
528 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
529 * oracle plugin: This new plugin allows you to connect to an Oracle
530 database and use SQL to gather custom statistics from it. It is
531 similar to the already existing PostgreSQL plugin.
532 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
534 * perl plugin: Export the newly added plugin_write() to Perl plugins.
535 * perl plugin: Added support for `notification meta data'.
536 * perl plugin: Added support for the `filter chain' infrastructure by
537 allowing plugins to register `matches' and `targets'.
538 * postgresql plugin: The preferred configuration syntax has been
539 updated to be in line with the syntax used by the new dbi and oracle
540 plugins. The compatibility code for the old syntax is present.
541 Support for the new `Result' blocks and the interval parameter has
543 * processes plugin: Stacksize and virtual memory usage statistics have
544 been added. Portability fixes.
545 * rrdcached plugin: This new plugin uses the (still in development)
546 RRD accelerator daemon, rrdcached. This daemon works very similar to
547 the original rrdtool plugin of collectd, but adds some more nice
549 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
552 2009-05-09, Version 4.5.4
553 * Build system, various plugins: Many build fixes for FreeBSD,
554 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
555 for many fixes and providing a build system for many platforms,
556 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
557 providing an OpenBSD system.
558 * collectd: Fix a potential race condition when creating directories.
559 * battery plugin: Don't complain about a missing directory every
561 * dns plugin: Slight portability fixes.
562 * exec plugin: Allow executed programs to close STDERR. Thanks to
563 Thorsten von Eicken for reporting this problem.
564 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
565 Tomasz Pala for the patch.
566 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
568 * rrdtool plugin: Fix a possible race condition: If the network plugin
569 is initialized and dispatches a value before the rrdtool plugin is
570 initialized, the daemon may crash.
571 * memory plugin: Fix a potential problem under Solaris.
573 2009-02-22, Version 4.5.3
574 * build system: The check for libupsclient even when `pkg-config' is
576 * collectd: Fix error handling in the global cache.
577 * Collectd::Unixsock: Error handling has been improved.
578 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
580 * ipmi plugin: Fix an off-by-one error which could cause segmentation
581 faults. Thanks to Peter Holik for his patch.
582 * tcpconns plugin: An endianness problem has been fixed in the *BSD
583 code. Thanks to "thated" for reporting this.
585 2009-01-02, Version 4.5.2
586 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
587 file may be in both locations, especially when the database was
588 installed in a non-standard path. Thanks to Dusty Doris for
590 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
591 Solaris, in the configure script automatically.
592 * build system, tcpconns plugin: Check for `kvm_nlist' and
593 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
594 library with similar functions to the BSD variant, but doesn't
595 provide these necessary functions.
596 * collectd.conf(5): Various fixes and clarifications.
597 * collectd: Remove a GNUism (unnamed unions), thus improving
599 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
600 This solves portability problems, especially for Solaris.
601 * dns plugin: Fix a portability problem with NetBSD.
602 * filecount plugin: Fix an off-by-one error. This error may cause a
604 * network plugin: Fix the handling of `type' in the network protocol.
605 Due to a programming mistake, only 4 or 8 bytes would be copied to a
606 much larger buffer. This caused the `type' to be transferred much
607 more often than necessary. In some cases, e. g. the `cpu' and
608 `cpufreq' plugins being used at the same time, data may be corrupted
609 in those files. Thanks to Bruno Prémont for debugging and reporting
611 * processes plugin: Fix a possible segmentation fault when specifying
612 invalid configuration options.
613 * unixsock plugin: Make sure the initialization function is run only
614 once. This resolves a file descriptor leak under systems which run
615 the initialization more than once, such as Solaris.
617 2008-10-16, Version 4.5.1
618 * build system: Change `--enable-<plugin>' to abort with an error if
619 dependencies are not met. Thanks to Bruno Prémont for the patch.
620 Also, the poisoning of various string functions has been restricted
622 * collectd: Fix a memory leak in the global value cache. With every
623 *missing* value a couple of bytes would be leaked. Another memory
624 leak in the configuration handling code has been fixed. Thanks to
625 Niraj Tolia for reporting these issues.
626 * collectd: Fix an off-by-one error in the ignorelist functionality.
627 When using regular expressions, the last character would be missing,
628 possibly matching differently from what one would expect.
629 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
631 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
632 Linzberger for reporting the bug.
633 * iptables plugin: Fix an off-by-one error. If a string was just one
634 character too long, it was truncated instead of reporting an error.
635 * network plugin: Fix a memory leak in the configuration handling
636 code. Thanks to Niraj Tolia for reporting this issue.
637 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
638 * postgresql plugin: Don't reopen connection during reinitialization.
639 This fixes a bug under Solaris and potentially other platforms.
640 Missing calls to `PQclear' have been added, too. This fixes memory
641 leaks. Thanks to ``Admin'' for reporting these bugs.
642 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
644 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
645 problems with some `libc's. Thanks to Matthias Lay for reporting the
648 2008-09-04, Version 4.5.0
649 * collectd: Added the ability to flush certain identifiers.
650 * collectd: The concept of `notification meta data' has been
652 * filecount plugin: The new filecount plugin counts the number of
653 files in a directory and its subdirectories.
654 * ipmi plugin: Sensor names have been changed to ensure unique names.
655 Notifications upon added and removed sensors can now be generated.
656 * notify_desktop plugin: This new plugin sends notifications to the
657 X desktop using the structure defined in the `Desktop Notification
659 * notify_email plugin: This new plugin sends out notifications via
660 email, using the `esmtp' library.
661 * onewire plugin: The new experimental(!) onewire plugin reads values,
662 such as temperatures, from sensors connected to the computer via the
664 * perl plugin: Improved synchronized access to internal data structures
665 and fixed a possible dead-lock.
666 * perl plugin: Added the ability to flush certain identifiers and marked
667 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
669 * perl plugin: Added the ability to configure Perl plugins.
670 * postgresql plugin: The new postgresql plugin collects statistics
671 about or from a PostgreSQL database.
672 * processes plugin: The `ProcessMatch' option has been added.
673 * rrdtool plugin: Implement throttling of the `update queue' to lessen
675 * tcpconns plugin: This plugin has been ported to OpenBSD.
676 * thermal plugin: The new thermal plugin collects system temperatures
677 using Linux ACPI thermal zone data.
679 2009-01-02, Version 4.4.5
680 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
681 file may be in both locations, especially when the database was
682 installed in a non-standard path. Thanks to Dusty Doris for
684 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
685 Solaris, in the configure script automatically.
686 * collectd.conf(5): Various fixes and clarifications.
687 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
688 portability problems, especially for Solaris.
689 * dns plugin: Fix a portability problem with NetBSD.
690 * network plugin: Fix the handling of `type' in the network protocol.
691 Due to a programming mistake, only 4 or 8 bytes would be copied to a
692 much larger buffer. This caused the `type' to be transferred much
693 more often than necessary. In some cases, e. g. the `cpu' and
694 `cpufreq' plugins being used at the same time, data may be corrupted
695 in those files. Thanks to Bruno Prémont for debugging and reporting
697 * unixsock plugin: Make sure the initialization function is run only
698 once. This resolves a file descriptor leak under systems which run
699 the initialization more than once, such as Solaris.
701 2008-10-16, Version 4.4.4
702 * build system: Change `--enable-<plugin>' to abort with an error if
703 dependencies are not met. Thanks to Bruno Prémont for the patch.
704 Also, the poisoning of various string functions has been restricted
706 * collectd: Fix a memory leak in the global value cache. With every
707 *missing* value a couple of bytes would be leaked. Another memory
708 leak in the configuration handling code has been fixed. Thanks to
709 Niraj Tolia for reporting these issues.
710 * collectd: Fix an off-by-one error in the ignorelist functionality.
711 When using regular expressions, the last character would be missing,
712 possibly matching differently from what one would expect.
713 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
715 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
716 Linzberger for reporting the bug.
717 * network plugin: Fix a memory leak in the configuration handling
718 code. Thanks to Niraj Tolia for reporting this issue.
719 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
720 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
721 problems with some `libc's. Thanks to Matthias Lay for reporting the
724 2008-09-01, Version 4.4.3
725 * collectd: Fix a memory leak in the threshold checking code.
726 * memcached plugin: Fix a too short timeout and a related file
728 * memory plugin: A typo in the libstatgrab code has been fixed.
729 * snmp plugin: Fix a possible memory leak.
731 2008-07-15, Version 4.4.2
732 * build system: Use pkg-config to detect the upsclient library.
733 * collectd: Try even harder to determine the endianess of the
734 architecture collectd is being built on.
735 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
737 * dns plugin: Fix compilation errors with BIND versions 19991001
739 * network plugin: Bugfix in the init routine: The init function
740 cleared a buffer regardless of its contents. This could lead to lost
741 values under Solaris.
742 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
743 * vserver plugin: Remove usage of the thread-unsafe `readdir'
745 * wireless plugin: Work around incorrect noise and power values
746 returned by some broken drivers.
748 2008-06-03, Version 4.4.1
749 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
750 to kyrone for reporting this.
751 * collectd: Fixed min/max output in notifications generated by
753 * collectd-nagios: Fix the protocol used to communicate with the
755 * perl plugin: Fail noisily, but don't shutdown the daemon, if
756 initialization has errors. An issue with Perl 5.10 has been fixed.
757 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
758 René Rebe and Siegmund Gorr for reporting this.
760 2008-05-06, Version 4.4.0
761 * collectd: Internal code cleanups.
762 * collectd: Added support for a `Flush' command in the unixsock and
763 exec plugins. This command can be used to force a plugin (or all) to
764 flush its values to disk.
765 * collectd: Thresholds can now be configured to apply to one data
766 source only, making it possible to configure different thresholds
767 for each data source.
768 * apache, nginx plugins: Added the possibility to disable host and/or
770 * ascent plugin: The new ascent plugin reads and parses the statistics
771 page of an Ascent server.
772 * cpu plugin: Support for the statgrab library has been added.
773 * disk plugin: The possibility to ignore certain disks or collect only
774 specific disks has been added.
775 * disk plugin: Support for the statgrab library has been added.
776 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
777 sensor values via IPMI, the intelligent platform management
779 * iptables plugin: The iptc library that is used by the iptables
780 plugin has been added to the distribution, because it is not
781 provided by all distributions and removed from at least one.
782 * powerdns plugin: The new powerdns plugin reads statistics from an
783 authoritative or a recursing PowerDNS name server.
784 * rrdtool plugin: The size of the files generated with the default
785 configuration has been decreased.
786 * tail plugin: The new tail plugin can be used to gather statistics by
787 continuously reading from log files.
788 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
789 TeamSpeak2 server and collects statistics about the number of users
790 and number of channels.
791 * users plugin: Support for the statgrab library has been added.
792 * vmem plugin: The new vmem plugin collects very detailed statistics
793 about the virtual memory subsystem of Linux.
795 2008-08-30, Version 4.3.4
796 * Build system: Improved detection of and linking with the statgrab
798 * collectd: Portability fixes, especially to determine endianess more
800 * Various plugins: Fix format strings.
801 * disk plugin: A fix for giving disks under Linux 2.4 the right names
802 again has been applied.
803 * memcached plugin: Fix a too short timeout and a related file
805 * memory plugin: A typo in the libstatgrab code has been fixed.
806 * network plugin: A fix in the initialization function solves problems

809 * vserver plugin: A thread-unsafe function has been replaced.
810 * wireless plugin: A work-around for broken wireless drivers has been
813 2008-04-22, Version 4.3.3
814 * build system: Improved detection of several libraries, especially if
815 they are in non-standard paths.
816 * build system: Portability fixes: Automatically define "_REENTRANT"
817 if the libc expects it.
818 * collectd: Error and warning messages have been improved.
819 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
821 * apache plugin: Allocate new memory when reading a webpage instead of
822 using a buffer of static size.
823 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
825 * hddtemp plugin: Error and warning messages have been improved.
826 * sensors plugin: Fix sensor collection for some chip types.
828 2008-03-29, Version 4.3.2
829 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
830 `Persist' threshold options.
831 * collectd: Fix handling of missing values in the global value cache.
832 * collectd: Improved error messages when parsing the configuration.
833 * sensors plugin: Fix temperature collection with libsensors4.
834 * unixsock plugin: Fix mixed input and output operation on streams.
835 * wireless plugin: Fix reading noise value.
837 2008-03-05, Version 4.3.1
838 * exec plugin: Set supplementary group IDs.
840 + Use `memcpy' when constructing/parsing a package to avoid
841 alignment problems on weird architectures, such as Sparc.
842 + Translate doubles to/from the x86 byte representation to ensure
843 cross-platform compatibility.
844 * ping plugin: Correct the handling of the `TTL' setting.
845 * swap plugin: Reapply a patch for Solaris.
846 * tcpconns plugin: Portability improvements.
848 2008-02-18, Version 4.3.0
849 * collectd: Notifications have been added to the daemon. Notifications
850 are status messages that may be associated with a data instance.
851 * collectd: Threshold checking has been added to the daemon. This
852 means that you can configure threshold values for each data
853 instance. If this threshold is exceeded a notification will be
855 * collectd: The new `FQDNLookup' option tells the daemon to use the
856 full qualified domain name as the hostname, not just the host part
857 es returned by `gethostname(2)'.
858 * collectd: Support for more than one `TypesDB' file has been added.
859 This is useful when one such file is included in a package but one
860 wants to add custom type definitions.
861 * collectd: The `Include' config option has been expanded to handle
862 entire directories and shell wildcards.
863 * collectdmon: The new `collectdmon' binary detects when collectd
864 terminates and automatically restarts it again.
865 * csv plugin: The CSV plugin is now able to store counter values as a
866 rate, using the `StoreRates' configuration option.
867 * exec plugin: Handling of notifications has been added and the
868 ability to pass arguments to the executed programs has been added.
869 * hddtemp plugin: The new `TranslateDevicename' option lets you
870 disable the translation from device names to major-minor-numbers.
871 * logfile plugin: Handling of notifications has been added.
872 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
873 domain name lookups in this plugin.
874 * perl plugin: Many internal changes added support for handling multiple
875 threads making the plugin reasonably usable inside collectd. The API has
876 been extended to support notifications and export global variables to
877 Perl plugins; callbacks now have to be identified by name rather than a
878 pointer to a subroutine. The plugin is no longer experimental.
879 * uuid plugin: The new UUID plugin sets the hostname to an unique
880 identifier for this host. This is meant for setups where each client
881 may migrate to another physical host, possibly going through one or
882 more name changes in the process. Thanks to Richard Jones from
883 Red Hat's Emerging Technology group for this plugin.
884 * libvirt: The new libvirt plugin uses the `libvirt' library to query
885 CPU, disk and network statistics about guest systems on the same
886 physical server. Thanks to Richard Jones from Red Hat's Emerging
887 Technology group for this plugin.
889 2008-04-22, Version 4.2.7
890 * build system: Improved detection of several libraries, especially if
891 they are in non-standard paths.
892 * build system: Portability fixes: Automatically define "_REENTRANT"
893 if the libc expects it.
894 * collectd: Error and warning messages have been improved.
895 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
897 * apache plugin: Allocate new memory when reading a webpage instead of
898 using a buffer of static size.
899 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
901 * hddtemp plugin: Error and warning messages have been improved.
902 * sensors plugin: Fix sensor collection for some chip types.
904 2008-03-29, Version 4.2.6

906 * sensors plugin: Fix temperature collection with libsensors4.
907 * unixsock plugin: Fix mixed input and output operation on streams.
908 * wireless plugin: Fix reading noise value.
910 2008-03-04, Version 4.2.5
911 * apache plugin: Improved initialization and error messages.
912 * exec plugin: Set supplementary group IDs.
914 + Create separate threads for reading from the socket and parsing
915 and dispatching incoming packets. Versions prior to this may have
916 problems in high-load situations, where the socket receive buffers
917 overflows, resulting in gaps in the data.
918 + Use `memcpy' when constructing/parsing a package to avoid
919 alignment problems on weird architectures, such as Sparc.
920 + Translate doubles to/from the x86 byte representation to ensure
921 cross-platform compatibility.
922 * ping plugin: Correct the handling of the `TTL' setting.
923 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
924 * swap plugin: Reapply a patch for Solaris.
925 * tcpconns plugin: Portability improvements.
927 2008-01-21, Version 4.2.4
928 * unixsock plugin: A bug in the unixsock plugin caused it not to set
929 the permission on the socket as documented in the manpage. Thanks to
930 Evgeny Chukreev for fixing this issue.
931 * collectd: The documentation has been improved.
933 2007-12-28, Version 4.2.3
934 * sensors plugin: Updated the plugin to build and work with version 3
935 of the libsensors library.
937 2007-12-15, Version 4.2.2
938 * nginx plugin: Incorrect comparison of strings lead to a segfault
939 when using the plugin. Thanks to Saulius Grigaliunas for fixing
941 * logfile plugin: The config option `Timestamp' was handled
942 incorrectly and basically always active. Thanks to Luke Heberling
945 2007-11-08, Version 4.2.1
946 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
948 * snmp plugin: Fix a memory leak.
950 2007-10-27, Version 4.2.0
951 * collectd: The new config option `Include' lets you include other
952 configfiles and thus split up your config into smaller parts. This
953 may be especially interesting for the snmp plugin to keep the data
954 definitions separate from the host definitions.
955 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
956 (number of connections, octets and packets for each service and
957 destination). Thanks to Sebastian Harl for this plugin.
958 * memcached plugin: The new `memcached' plugin connects to a memcached
959 daemon process and collects statistics of this distributed caching
960 system. Thanks to Antony Dovgal for contributing this plugin.
961 * nginx plugin: The new `nginx' plugin reads the status page of an
962 nginx daemon and saves the handled connections and requests.
963 * perl plugin: Many changes, including the added `EnableDebugger'
964 config option which lets you debug your Perl plugins more easily.
965 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
966 be more thread-safe otherwise by locking calls to the library.
967 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
968 correct the values returned by SNMP-agents. If a <data> block is
969 defined as `table' the instance is now optional. The sequence number
970 is used as the type-instance in this case. The new `InstancePrefix'
971 option allows to add arbitrary prefixes to the type-instance.
972 * tcpconns plugin: The new `tcpconns' plugin collects the number of
973 certain TCP connections and what state they're in. This can be used
974 to see how many connections your FTP server has to handle or how
975 many outgoing connections your mailserver has open.
977 2008-01-11, Version 4.1.6
978 * unixsock plugin: A bug in the unixsock plugin caused it not to set
979 the permission on the socket as documented in the manpage. Thanks to
980 Evgeny Chukreev for fixing this issue.
981 * collectd: The documentation has been improved.
983 2007-12-27, Version 4.1.5
984 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
986 * sensors plugin: Updated the plugin to build and work with version 3
987 of the libsensors library.
989 2007-11-08, Version 4.1.4
990 * Build system: Improve detection of the rrd library, especially if
991 it's in a non-standard location.

999 2007-10-24, Version 4.1.3
1000 * collectd: A build issue under Solaris has been resolved by renaming
1002 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1003 be more thread-safe otherwise by locking calls to the library.
1005 2007-09-28, Version 4.1.2
1006 * apcups plugin: Fix reporting of the `load percent' data.
1007 * wireless plugin: Correct the handling of cards returning signal and

1028 whatever the client thinks is `now'..
1030 2007-09-01, Version 4.1.0
1031 * Build system: The build system has been changed to automatically
1032 disable all plugins, which are missing dependencies. The dependency
1033 checking has been removed from the plugins themselves to remove
1035 * Flexible interval: The interval of collected data is now sent along
1036 with the data itself over the network, so that the interval-settings
1037 of server and clients no longer needs to match.
1038 * netlink plugin: The new `netlink' plugin connects to the Linux
1039 kernel using a netlink socket and uses it to query information about

1059 with the broken GNU version of `strerror_r'.
1060 * collectd: Write an error message to STDERR when loading of a plugin
1062 * apcups plugin: Fix the `types' used to submit the values: They still
1063 has an `apcups_' prefix which doesn't work anymore.
1064 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1065 whatever the client thinks is `now'..
1067 2007-08-26, Version 4.0.7
1068 * documentation: Some typos have been fixed and some information has
1070 * build system: Many fixes for detecting libraries in unusual places,
1071 such as on RedHat systems. The affected libraries are `libcurl',
1072 `libmysql', and `libupsclient'.
1073 * network plugin: Allow the `Port' option to be specified as a number
1074 (i. e. without quotes).
1075 * nut plugin: A fix allows linking the nut plugin against
1076 libupsclient, version >= 2.2.0.
1077 * processes plugin: Fix a potential segmentation fault.
1079 2007-07-30, Version 4.0.6
1080 * sensors plugin: Fix the ignorelist functionality: Only the `type
1081 instance' was used to match against the list, but the documentation
1082 told otherwise. This release fixes the code, so it complies with the
1084 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1085 configuration messages will end up in the logging facility.
1086 * conrtib/fedora: The contributed specfile for Fedora has been
1089 2007-07-05, Version 4.0.5
1090 * Portability: More fixes for OpenBSD have been included.

1112 * iptables plugin: A bug in the configuration routine has been fixed.
1113 Setting a comment in the configfile will no longer cause a
1116 2007-06-03, Version 4.0.0
1117 * collectd: The plugin-infrastructure has been changed to allow for
1118 more types of plugins, namely `write' and `log' plugins.
1119 * collectd: The read-function has been changed to read many plugins in
1120 parallel, using threads. Thus, plugins generally need to use
1121 thread-safe functions from now on.
1122 * collectd: The '-t' command line options allows to perform syntax tests
1123 of the configuration file and exit immediately.
1124 * csv plugin: The new `csv' plugin handles output to `comma separated
1126 * rrdtool plugin: The new `rrdtool' plugin handles output to
1127 RRD-files. Data can be cached to combine multiple updates into one
1128 write to increase IO-performance.
1129 * network plugin: The new `network' plugin handles IO via the network.
1130 It implements a different, much more extensible protocol which can
1131 combine many values in one packet, decreasing the number of UDP-
1132 packets being sent. It can read from and send to the network and
1133 with the appropriate configuration even forward packets to other
1135 * unixsock plugin: The new `unixsock' plugin provides an interface to
1136 communicate with the daemon while it is running. Right now the
1137 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1139 * perl plugin: The new `perl' plugin allows you to write extensions
1140 for collectd in the scripting-language Perl.
1141 * logfile plugin: The new `logfile' plugin writes logmessages to files
1142 or STDOUT or STDERR.
1143 * syslog plugin: The new `syslog' plugin sends logmessages to the
1144 system's syslog daemon.
1145 * entropy plugin: The new `entropy' plugin collects the amount of
1146 entropy currently being available to the system.
1147 * exec plugin: The new `exec' plugin forks child processes and reads
1148 back values provided by the forked processes.
1149 * iptables plugin: The new `iptables' plugin reads counters from
1150 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1152 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1153 to Peter Holik for contributing this plugin.
1154 * nut plugin: The new `nut' plugin connects the upsd of the `network
1155 ups tools' and reads information about the connected UPS.
1156 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1157 connections) field was added by Florent Monbillard.
1158 * collectd-nagios: The new `collectd-nagios' binary queries values
1159 from collectd, parses them and exits according to Nagios-standards.
1160 * manpages: The manpages have been improved a lot.
1162 2007-09-28, Version 3.11.7
1163 * wireless plugin: Correct the handling of cards returning signal and
1164 noise quality as percentage.
1166 2007-08-31, Version 3.11.6
1167 * processes plugin: Fix a potential segmentation fault.
1169 2007-05-29, Version 3.11.5
1170 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1171 * ntpd plugin: Fix a potential buffer overflow.
1172 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1173 were accounted as `zombies'.
1175 2007-04-10, Version 3.11.4
1176 * dns plugin: Change the order of includes to make the plugin compile
1179 2007-03-30, Version 3.11.3
1180 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1181 of the unused `COLLECT_KSTAT'.
1183 2007-02-11, Version 3.11.2
1184 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1185 NULL-pointer may have been passed to `printf' which causes a
1186 segfault with some libcs.
1188 2007-02-10, Version 3.11.1
1189 * df plugin: Some wrong defines have been fixed so the plugin works
1190 under Solaris again.
1191 * dns plugin: The usage of a struct has been fixed to work with
1193 * processes plugin: Some missing defines have been added so the plugin
1194 compiles cleanly under FreeBSD and presumably other UNIXes.
1196 2006-12-22, Version 3.11.0
1197 * collectd: The new command line option `-P' makes it easier for
1198 distributors to change the location of PID-files.
1199 * collectd: The daemon shuts down faster now which makes it easier to
1200 write init.d-scripts for it.
1201 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1202 caused problems every now and then.
1203 * df plugin: New config options allow to ignore certain mountpoints,
1204 filesystem types or devices.
1205 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1206 and interprets it. It collects traffic as well as qtype, opcode and
1208 * email plugin: Sebastian Harl has contributed this plugin which
1209 counts received mails in categories (e. g. ham, spam, virus), spam
1210 score (as given by SpamAssassin) and check types.
1211 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1212 uses `mbmon' to gather information from sensors on the motherboard.
1213 * processes plugin: Collect detailed statistics for configured
1214 processes, that's process and thread count, CPU usage, resident
1215 segment size and pagefaults.
1216 * multimeter plugin: Peter Holik contributed a new plugin which
1217 queries multimeters.
1218 * sensors plugin: Lubos Stanek has put much effort into improving this
1219 plugin, including `extended naming', collection of voltage values
1220 and the possibility to ignore certain values.
1222 2006-12-21, Version 3.10.4
1223 * Max Kellermann has identified a bug in the server routine: When
1224 opening a socket fails the daemon will (re)try opening the socket in
1225 an endless loop, ultimately leading to a `EMFILE' error.
1227 2006-11-04, Version 3.10.3
1228 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1229 ntpd's reply was sent in more than one packet, the buffer size was
1230 calculated incorrectly, resulting in the reading of uninitialized or
1233 2006-11-01, Version 3.10.2
1234 * The sample config file has been improved.
1235 * Errors in the manpages have been corrected.
1236 * The ping-plugin now adds hosts during initialization, not during
1237 startup. This speeds up startup when no network connectivity is
1238 available. Also, the hosts are being added later when the network is
1240 * Improved BSD-support for the df-plugin.
1241 * Fixed syntax errors in the swap-plugin for Mac OS X.
1242 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1244 * Don't disable the mysql-plugin if connecting to the database fails
1245 during initialization. Instead, try again in increasing intervals.
1247 2006-07-19, Version 3.10.1
1248 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1249 the apcups cannot be reached, unconnected sockets will pile up and
1250 eventually lead to `Too many open files' errors.
1252 2006-07-09, Version 3.10.0
1253 * The `disk' plugin has been ported to Darwin.
1254 * The `battery' plugin should work on many Apple computers now.
1255 * The `traffic' plugin can now ignore certain interfaces. Also,
1256 statistics for sent/received packets and errors have been added.
1257 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1258 to Anthony Gialluca for contributing this plugin and providing me
1259 with a test environment :)
1260 * A plugin for monitoring an NTP instance and the local clock drift
1263 2006-06-25, Version 3.9.4
1264 * The Solaris code in the `swap' plugin has been changed to reflect
1265 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1267 * The debugging system has been fixed to work with the Sun libc.
1268 * When built without librrd the variable `operating_mode' could be
1269 uninitialized. Thanks to David Elliot for reporting the bug.
1271 2006-06-01, Version 3.9.3
1272 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1273 operating systems also profit from the changes, but I wasn't able to
1275 * Changed the build system to find the netinet-includes under FreeBSD
1276 and therefore successfully build the `liboping' library there.
1278 2006-05-09, Version 3.9.2
1279 * Applied a patch to the `liboping' library. Due to a bug in the
1280 sequence checking the `ping' plugin stopped working after
1281 approximately 7.6 days.
1283 2006-05-09, Version 3.8.5
1284 * Applied a patch to the `liboping' library. Due to a bug in the
1285 sequence checking the `ping' plugin stopped working after
1286 approximately 7.6 days.
1288 2006-04-21, Version 3.9.1
1289 * Build issues with Solaris and possible other architectures have been
1291 * Problems when building the `apache'-plugin without `libcurl' have
1293 * A bug in the `ping' plugin has been fixed. Sorry folks.
1295 2006-04-02, Version 3.9.0
1296 * A plugin to monitor the Apache webserver has been added.
1297 <http://httpd.apache.org/>
1298 * A plugin to collect statistics about virtual servers using VServer.
1299 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1301 * A plugin for wireless LAN cards has been added. It monitors signal
1302 strength, link quality and noise ratio..
1303 * A plugin for Apple hardware sensors has been added.
1304 * An option to compile collectd with different `step' and `heartbeat'
1305 settings has been added. The size of RRAs is no longer static but
1306 calculated based on the settings for `step' and `width'.
1307 * The `ping' plugin can now be configured to use a certain TTL.
1308 * A plugin to monitor the hardware sensors of Apple computers has been
1310 * The plugins `cpu', `memory', `processes' and `traffic' have been
1311 ported to Mach/Darwin (Mac OS X).
1312 * The `log mode' has been contributed by Christophe Kalt. It writes
1313 the data into text files rather than RRD files.
1315 2006-04-09, Version 3.8.4
1316 * Applied patch by Vincent Stehlé which improves the disk-name
1317 resolution in the `hddtemp' plugin for Linux systems.
1319 2006-04-02, Version 3.8.3
1320 * Applied a patch by James Byers: The MySQL plugin was not working
1321 with MySQL 5.0.2 or later.
1323 2006-03-14, Version 3.8.2
1324 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1325 the GNU libc, because it points to `/etc/fstab' rather than
1328 2006-03-13, Version 3.8.1
1329 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1330 * Fixes in the debian `postinst' and `init.d' scripts.
1332 2006-03-09, Version 3.8.0
1333 * The `ping' plugin no longer uses `libping' but a self written
1334 library named `liboping'. With this library it's possible to ping
1335 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1337 2006-02-18, Version 3.7.2
1338 * A simple bug in the `battery' plugin has been fixed. It should now
1339 work with ACPI based batteries as well. Thanks to Sebastian for
1341 * Fixing a bug that prevented collectd to be built without librrd.
1342 Thanks to Werner Heuser for reporting it.
1344 2006-02-04, Version 3.7.1
1345 * The new network code has been improved to build with older versions
1347 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1348 to Tommie Gannert for this patch.
1350 2006-01-30, Version 3.7.0
1351 * The `battery' plugin has been added. It collects information about
1353 * The MySQL plugin has been improved: It now writes two more RRD
1354 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1355 * The `cpufreq' plugin now reads another file since the file it did
1356 read so far causes much overhead in the kernel. Also, you need root
1357 to read the old file, but not to read the new one.
1358 * The `hddtemp' plugin can now be configured to connect to another
1359 address and/or port than localhost.
1360 * The `df' plugin now prefers `statvfs' over `statfs'.
1361 * The network code has been rewritten. collectd now supports unicast
1362 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1363 be set in the configfile.
1365 2006-01-24, Version 3.6.2
1366 * Due to a bug in the configfile handling collectd wouldn't start in
1367 client mode. This released fixes this.
1369 2006-01-20, Version 3.6.1
1370 * Due to a bug in `configure.in' all modules and the binary were
1371 linked against `libmysqlclient'. This issue is solved by this
1374 2006-01-17, Version 3.6.0
1375 * A config file has been added. This allows for loading only specific
1377 * A `df' plugin has been added.
1378 * A `mysql' plugin has been added.
1379 * The `ping' plugin doesn't entirely give up hope when a socket error
1380 occurred, but will back of and increase the intervals between tries.
1382 2006-01-21, Version 3.5.2
1383 * Fixed yet another bug in the signal handling.. Stupid typo..
1384 * Improved the ping plugin to not give up on socket errors (backport
1387 2005-12-18, Version 3.5.1
1388 * The PID-file is now deleted correctly when shutting down the daemon.
1389 * SIGINT and SIGTERM are now handled correctly.
1391 2005-12-16, Version 3.5.0 (Revision 326)
1392 * A bug in the `load' module under Solaris has been fixed.
1393 * The `users' module has been contributed by Sebastian Harl. It counts
1394 currently logged in users.
1395 * The CPU module now works under FreeBSD without the use of
1396 `libstatgrab', however SMP support is missing.
1397 * The default directories for the RRD files and the PID file now
1398 depend on the compile time setting of `localstatedir'.
1400 2005-11-15, Version 3.4.0 (Revision 236)
1401 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1402 from gentoo's bugzilla for writing the patch.
1403 * The build dependency for librrd has been removed. Binaries built
1404 without librrd are client-only and will multicast their value as
1405 with the `-c' argument.
1406 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1407 * The newly introduced `-f' switch prevents daemon initialization
1408 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1409 Barcellos for this patch.
1411 2005-11-04, Version 3.3.0 (Revision 216)
1412 * New modules have been added:
1413 - `serial', for monitoring traffic on the serial interfaces
1414 - `nfs', for graphing NFS procedure calls
1415 - `tape', traffic from/to tape devices
1416 * The memory.rrd now accepts more than 4Gig of memory.
1418 2005-10-26, Version 3.2.0 (Revision 200)
1419 * Support for graphing the processes has been added (thanks to Lyonel

1422 between polls up to one day.
1423 * The init.d files have been improved.
1424 * Problems with the spec file have been fixed.
1426 2005-10-16, Version 3.1.0 (Revision 194)
1427 * Added the `setsid' syscall to the startup code.
1428 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1430 2005-09-30, Version 3.0.0 (Revision 184)
1431 * The ability to send/receive data to/from the network (think
1432 multicast) has been added.
1433 * Modules have been split up into shared libraries can be loaded at
1434 runtime. The biggest advantage is that the core program doesn't need
1435 to be linked against an external library.
1436 * A patch by George Kargiotakis has been applied: It fixes the sensors
1437 behaviour then more than one sensor is being queried.
1439 2005-09-16, Version 2.1.0 (Revision 172)
1440 * A module for swap statistics has been added.
1442 2005-09-09, Version 2.0.0 (Revision 135)
1443 * Filenames can no longer be configured at program startup. The only
1444 options as of this version are the directory and ping hosts.
1445 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1446 Soft-IRQ statistics are added to `System'.
1447 * Diskstats now collect read and write bytes, not sectors.
1448 * Ping statistics can now be collected for more than one host. There
1449 is no default any more: If no host is given no host will be pinged.
1450 * A self-written patch for libping has been applied so it builds
1453 2005-09-01, Version 1.8.1 (Revision 123)
1454 * Much improved configure-script: libraries and features may now be
1456 * More detailed warnings/error messages when RRD update fails.
1458 2005-08-29, Version 1.8.0:
1459 * Support for collecting disk statistics under Solaris.
1461 2005-08-25, Version 1.7.0:
1462 * Support for libstatgrab[1] for load, memory usage and network
1463 traffic. CPU- and disk-usage are not (yet) supported, since
1464 libstatgrab returns insufficient information. I will contact the
1466 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1467 aren't necessarily counted linear which is now handled correctly.
1468 [1]: http://www.i-scream.org/libstatgrab/
1470 2005-08-21, Version 1.6.0:
1471 * Basic support for Solaris: System load and cpu-usage can be
1472 collected under Solaris, too. Other stats will follow later.
