495 * timediff match: Match for values with an invalid timestamp.
496 * value match: Select values by their data sources' values.
497 * notification target: Create and dispatch a notification.
498 * replace target: Replace parts of an identifier using regular
500 * set target: Set (overwrite) entire parts of an identifier.
501 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
502 statistics, allowing very detailed name server statistics. Thanks to
503 Bruno Prémont for this plugin.
504 * cpu plugin: Report `interrupt' separately when using
505 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
506 example for native OpenBSD support, has been added. Thanks to Simon
507 Kuhnle for the patch.
508 * csv plugin: Make it possible to write values to STDOUT instead of
509 files. This is meant for testing purposes mostly. The output written
510 to STDOUT is compatible with the exec plugin. Thanks to Doug
511 MacEachern for the patch.
512 * curl plugin: This new plugin can be used to read web pages and parse
513 them using the same mechanism that's used in the tail plugin.
514 * dbi plugin: This new plugin allows you to connect to a variety of
515 relational databases and use SQL to gather custom statistics from
516 it. It is similar to the already existing PostgreSQL plugin but uses
517 libdbi to communicate with the database(s).
518 * interface plugin: Use the ignorelist framework when selecting /
519 ignoring interfaces. This allows one to use regular expressions to
520 select interfaces, too.
521 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
522 Thanks to Bruno Prémont for this patch.
523 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
525 * mysql plugin: Allow connecting to a database via the UNIX domain
526 socket, too. Thanks to Mirko Buffoni for the patch.
527 * network plugin: Further performance improvements for the receive
528 code. This hopefully will help very large setups.
529 * openvpn plugin: This new plugin collects statistics provided by the
530 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
531 * oracle plugin: This new plugin allows you to connect to an Oracle
532 database and use SQL to gather custom statistics from it. It is
533 similar to the already existing PostgreSQL plugin.
534 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
536 * perl plugin: Export the newly added plugin_write() to Perl plugins.
537 * perl plugin: Added support for `notification meta data'.
538 * perl plugin: Added support for the `filter chain' infrastructure by
539 allowing plugins to register `matches' and `targets'.
540 * postgresql plugin: The preferred configuration syntax has been
541 updated to be in line with the syntax used by the new dbi and oracle
542 plugins. The compatibility code for the old syntax is present.
543 Support for the new `Result' blocks and the interval parameter has
545 * processes plugin: Stacksize and virtual memory usage statistics have
546 been added. Portability fixes.
547 * rrdcached plugin: This new plugin uses the (still in development)
548 RRD accelerator daemon, rrdcached. This daemon works very similar to
549 the original rrdtool plugin of collectd, but adds some more nice
551 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
554 2009-05-09, Version 4.5.4
555 * Build system, various plugins: Many build fixes for FreeBSD,
556 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
557 for many fixes and providing a build system for many platforms,
558 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
559 providing an OpenBSD system.
560 * collectd: Fix a potential race condition when creating directories.
561 * battery plugin: Don't complain about a missing directory every
563 * dns plugin: Slight portability fixes.
564 * exec plugin: Allow executed programs to close STDERR. Thanks to
565 Thorsten von Eicken for reporting this problem.
566 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
567 Tomasz Pala for the patch.
568 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
570 * rrdtool plugin: Fix a possible race condition: If the network plugin
571 is initialized and dispatches a value before the rrdtool plugin is
572 initialized, the daemon may crash.
573 * memory plugin: Fix a potential problem under Solaris.
575 2009-02-22, Version 4.5.3
576 * build system: The check for libupsclient even when `pkg-config' is
578 * collectd: Fix error handling in the global cache.
579 * Collectd::Unixsock: Error handling has been improved.
580 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
582 * ipmi plugin: Fix an off-by-one error which could cause segmentation
583 faults. Thanks to Peter Holik for his patch.
584 * tcpconns plugin: An endianness problem has been fixed in the *BSD
585 code. Thanks to "thated" for reporting this.
587 2009-01-02, Version 4.5.2
588 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
589 file may be in both locations, especially when the database was
590 installed in a non-standard path. Thanks to Dusty Doris for
592 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
593 Solaris, in the configure script automatically.
594 * build system, tcpconns plugin: Check for `kvm_nlist' and
595 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
596 library with similar functions to the BSD variant, but doesn't
597 provide these necessary functions.
598 * collectd.conf(5): Various fixes and clarifications.
599 * collectd: Remove a GNUism (unnamed unions), thus improving
601 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
602 This solves portability problems, especially for Solaris.
603 * dns plugin: Fix a portability problem with NetBSD.
604 * filecount plugin: Fix an off-by-one error. This error may cause a
606 * network plugin: Fix the handling of `type' in the network protocol.
607 Due to a programming mistake, only 4 or 8 bytes would be copied to a
608 much larger buffer. This caused the `type' to be transferred much
609 more often than necessary. In some cases, e. g. the `cpu' and
610 `cpufreq' plugins being used at the same time, data may be corrupted
611 in those files. Thanks to Bruno Prémont for debugging and reporting
613 * processes plugin: Fix a possible segmentation fault when specifying
614 invalid configuration options.
615 * unixsock plugin: Make sure the initialization function is run only
616 once. This resolves a file descriptor leak under systems which run
617 the initialization more than once, such as Solaris.
619 2008-10-16, Version 4.5.1
620 * build system: Change `--enable-<plugin>' to abort with an error if
621 dependencies are not met. Thanks to Bruno Prémont for the patch.
622 Also, the poisoning of various string functions has been restricted
624 * collectd: Fix a memory leak in the global value cache. With every
625 *missing* value a couple of bytes would be leaked. Another memory
626 leak in the configuration handling code has been fixed. Thanks to
627 Niraj Tolia for reporting these issues.
628 * collectd: Fix an off-by-one error in the ignorelist functionality.
629 When using regular expressions, the last character would be missing,
630 possibly matching differently from what one would expect.
631 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
633 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
634 Linzberger for reporting the bug.
635 * iptables plugin: Fix an off-by-one error. If a string was just one
636 character too long, it was truncated instead of reporting an error.
637 * network plugin: Fix a memory leak in the configuration handling
638 code. Thanks to Niraj Tolia for reporting this issue.
639 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
640 * postgresql plugin: Don't reopen connection during reinitialization.
641 This fixes a bug under Solaris and potentially other platforms.
642 Missing calls to `PQclear' have been added, too. This fixes memory
643 leaks. Thanks to ``Admin'' for reporting these bugs.
644 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
646 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
647 problems with some `libc's. Thanks to Matthias Lay for reporting the
650 2008-09-04, Version 4.5.0
651 * collectd: Added the ability to flush certain identifiers.
652 * collectd: The concept of `notification meta data' has been
654 * filecount plugin: The new filecount plugin counts the number of
655 files in a directory and its subdirectories.
656 * ipmi plugin: Sensor names have been changed to ensure unique names.
657 Notifications upon added and removed sensors can now be generated.
658 * notify_desktop plugin: This new plugin sends notifications to the
659 X desktop using the structure defined in the `Desktop Notification
661 * notify_email plugin: This new plugin sends out notifications via
662 email, using the `esmtp' library.
663 * onewire plugin: The new experimental(!) onewire plugin reads values,
664 such as temperatures, from sensors connected to the computer via the
666 * perl plugin: Improved synchronized access to internal data structures
667 and fixed a possible dead-lock.
668 * perl plugin: Added the ability to flush certain identifiers and marked
669 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
671 * perl plugin: Added the ability to configure Perl plugins.
672 * postgresql plugin: The new postgresql plugin collects statistics
673 about or from a PostgreSQL database.
674 * processes plugin: The `ProcessMatch' option has been added.
675 * rrdtool plugin: Implement throttling of the `update queue' to lessen
677 * tcpconns plugin: This plugin has been ported to OpenBSD.
678 * thermal plugin: The new thermal plugin collects system temperatures
679 using Linux ACPI thermal zone data.
681 2009-01-02, Version 4.4.5
682 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
683 file may be in both locations, especially when the database was
684 installed in a non-standard path. Thanks to Dusty Doris for
686 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
687 Solaris, in the configure script automatically.
688 * collectd.conf(5): Various fixes and clarifications.
689 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
690 portability problems, especially for Solaris.
691 * dns plugin: Fix a portability problem with NetBSD.
692 * network plugin: Fix the handling of `type' in the network protocol.
693 Due to a programming mistake, only 4 or 8 bytes would be copied to a
694 much larger buffer. This caused the `type' to be transferred much
695 more often than necessary. In some cases, e. g. the `cpu' and
696 `cpufreq' plugins being used at the same time, data may be corrupted
697 in those files. Thanks to Bruno Prémont for debugging and reporting
699 * unixsock plugin: Make sure the initialization function is run only
700 once. This resolves a file descriptor leak under systems which run
701 the initialization more than once, such as Solaris.
703 2008-10-16, Version 4.4.4
704 * build system: Change `--enable-<plugin>' to abort with an error if
705 dependencies are not met. Thanks to Bruno Prémont for the patch.
706 Also, the poisoning of various string functions has been restricted
708 * collectd: Fix a memory leak in the global value cache. With every
709 *missing* value a couple of bytes would be leaked. Another memory
710 leak in the configuration handling code has been fixed. Thanks to
711 Niraj Tolia for reporting these issues.
712 * collectd: Fix an off-by-one error in the ignorelist functionality.
713 When using regular expressions, the last character would be missing,
714 possibly matching differently from what one would expect.
715 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
717 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
718 Linzberger for reporting the bug.
719 * network plugin: Fix a memory leak in the configuration handling
720 code. Thanks to Niraj Tolia for reporting this issue.
721 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
722 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
723 problems with some `libc's. Thanks to Matthias Lay for reporting the
726 2008-09-01, Version 4.4.3
727 * collectd: Fix a memory leak in the threshold checking code.
728 * memcached plugin: Fix a too short timeout and a related file
730 * memory plugin: A typo in the libstatgrab code has been fixed.
731 * snmp plugin: Fix a possible memory leak.
733 2008-07-15, Version 4.4.2
734 * build system: Use pkg-config to detect the upsclient library.
735 * collectd: Try even harder to determine the endianess of the
736 architecture collectd is being built on.
737 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
739 * dns plugin: Fix compilation errors with BIND versions 19991001
741 * network plugin: Bugfix in the init routine: The init function
742 cleared a buffer regardless of its contents. This could lead to lost
743 values under Solaris.
744 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
745 * vserver plugin: Remove usage of the thread-unsafe `readdir'
747 * wireless plugin: Work around incorrect noise and power values
748 returned by some broken drivers.
750 2008-06-03, Version 4.4.1
751 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
752 to kyrone for reporting this.
753 * collectd: Fixed min/max output in notifications generated by
755 * collectd-nagios: Fix the protocol used to communicate with the
757 * perl plugin: Fail noisily, but don't shutdown the daemon, if
758 initialization has errors. An issue with Perl 5.10 has been fixed.
759 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
760 René Rebe and Siegmund Gorr for reporting this.
762 2008-05-06, Version 4.4.0
763 * collectd: Internal code cleanups.
764 * collectd: Added support for a `Flush' command in the unixsock and
765 exec plugins. This command can be used to force a plugin (or all) to
766 flush its values to disk.
767 * collectd: Thresholds can now be configured to apply to one data
768 source only, making it possible to configure different thresholds
769 for each data source.
770 * apache, nginx plugins: Added the possibility to disable host and/or
772 * ascent plugin: The new ascent plugin reads and parses the statistics
773 page of an Ascent server.
774 * cpu plugin: Support for the statgrab library has been added.
775 * disk plugin: The possibility to ignore certain disks or collect only
776 specific disks has been added.
777 * disk plugin: Support for the statgrab library has been added.
778 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
779 sensor values via IPMI, the intelligent platform management
781 * iptables plugin: The iptc library that is used by the iptables
782 plugin has been added to the distribution, because it is not
783 provided by all distributions and removed from at least one.
784 * powerdns plugin: The new powerdns plugin reads statistics from an
785 authoritative or a recursing PowerDNS name server.
786 * rrdtool plugin: The size of the files generated with the default
787 configuration has been decreased.
788 * tail plugin: The new tail plugin can be used to gather statistics by
789 continuously reading from log files.
790 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
791 TeamSpeak2 server and collects statistics about the number of users
792 and number of channels.
793 * users plugin: Support for the statgrab library has been added.
794 * vmem plugin: The new vmem plugin collects very detailed statistics
795 about the virtual memory subsystem of Linux.
797 2008-08-30, Version 4.3.4
798 * Build system: Improved detection of and linking with the statgrab
800 * collectd: Portability fixes, especially to determine endianess more
802 * Various plugins: Fix format strings.
803 * disk plugin: A fix for giving disks under Linux 2.4 the right names
804 again has been applied.
805 * memcached plugin: Fix a too short timeout and a related file
807 * memory plugin: A typo in the libstatgrab code has been fixed.
808 * network plugin: A fix in the initialization function solves problems
810 * nginx plugin: A thread-unsafe function has been replaced.
811 * vserver plugin: A thread-unsafe function has been replaced.
812 * wireless plugin: A work-around for broken wireless drivers has been
815 2008-04-22, Version 4.3.3
816 * build system: Improved detection of several libraries, especially if
817 they are in non-standard paths.
818 * build system: Portability fixes: Automatically define "_REENTRANT"
819 if the libc expects it.
820 * collectd: Error and warning messages have been improved.
821 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
823 * apache plugin: Allocate new memory when reading a webpage instead of
824 using a buffer of static size.
825 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
827 * hddtemp plugin: Error and warning messages have been improved.
828 * sensors plugin: Fix sensor collection for some chip types.
830 2008-03-29, Version 4.3.2
831 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
832 `Persist' threshold options.
833 * collectd: Fix handling of missing values in the global value cache.
834 * collectd: Improved error messages when parsing the configuration.
835 * sensors plugin: Fix temperature collection with libsensors4.
836 * unixsock plugin: Fix mixed input and output operation on streams.
837 * wireless plugin: Fix reading noise value.
839 2008-03-05, Version 4.3.1
840 * exec plugin: Set supplementary group IDs.
842 + Use `memcpy' when constructing/parsing a package to avoid
843 alignment problems on weird architectures, such as Sparc.
844 + Translate doubles to/from the x86 byte representation to ensure
845 cross-platform compatibility.
846 * ping plugin: Correct the handling of the `TTL' setting.
847 * swap plugin: Reapply a patch for Solaris.
848 * tcpconns plugin: Portability improvements.
850 2008-02-18, Version 4.3.0
851 * collectd: Notifications have been added to the daemon. Notifications
852 are status messages that may be associated with a data instance.
853 * collectd: Threshold checking has been added to the daemon. This
854 means that you can configure threshold values for each data
855 instance. If this threshold is exceeded a notification will be
857 * collectd: The new `FQDNLookup' option tells the daemon to use the
858 full qualified domain name as the hostname, not just the host part
859 es returned by `gethostname(2)'.
860 * collectd: Support for more than one `TypesDB' file has been added.
861 This is useful when one such file is included in a package but one
862 wants to add custom type definitions.
863 * collectd: The `Include' config option has been expanded to handle
864 entire directories and shell wildcards.
865 * collectdmon: The new `collectdmon' binary detects when collectd
866 terminates and automatically restarts it again.
867 * csv plugin: The CSV plugin is now able to store counter values as a
868 rate, using the `StoreRates' configuration option.
869 * exec plugin: Handling of notifications has been added and the
870 ability to pass arguments to the executed programs has been added.
871 * hddtemp plugin: The new `TranslateDevicename' option lets you
872 disable the translation from device names to major-minor-numbers.
873 * logfile plugin: Handling of notifications has been added.
874 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
875 domain name lookups in this plugin.
876 * perl plugin: Many internal changes added support for handling multiple
877 threads making the plugin reasonably usable inside collectd. The API has
878 been extended to support notifications and export global variables to
879 Perl plugins; callbacks now have to be identified by name rather than a
880 pointer to a subroutine. The plugin is no longer experimental.
881 * uuid plugin: The new UUID plugin sets the hostname to an unique
882 identifier for this host. This is meant for setups where each client
883 may migrate to another physical host, possibly going through one or
884 more name changes in the process. Thanks to Richard Jones from
885 Red Hat's Emerging Technology group for this plugin.
886 * libvirt: The new libvirt plugin uses the `libvirt' library to query
887 CPU, disk and network statistics about guest systems on the same
888 physical server. Thanks to Richard Jones from Red Hat's Emerging
889 Technology group for this plugin.
891 2008-04-22, Version 4.2.7
892 * build system: Improved detection of several libraries, especially if
893 they are in non-standard paths.
894 * build system: Portability fixes: Automatically define "_REENTRANT"
895 if the libc expects it.
896 * collectd: Error and warning messages have been improved.
897 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
899 * apache plugin: Allocate new memory when reading a webpage instead of
900 using a buffer of static size.
901 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
903 * hddtemp plugin: Error and warning messages have been improved.
904 * sensors plugin: Fix sensor collection for some chip types.
906 2008-03-29, Version 4.2.6
907 * collectd: Improved error messages when parsing the configuration.
908 * sensors plugin: Fix temperature collection with libsensors4.
909 * unixsock plugin: Fix mixed input and output operation on streams.
910 * wireless plugin: Fix reading noise value.
912 2008-03-04, Version 4.2.5
913 * apache plugin: Improved initialization and error messages.
914 * exec plugin: Set supplementary group IDs.
916 + Create separate threads for reading from the socket and parsing
917 and dispatching incoming packets. Versions prior to this may have
918 problems in high-load situations, where the socket receive buffers
919 overflows, resulting in gaps in the data.
920 + Use `memcpy' when constructing/parsing a package to avoid
921 alignment problems on weird architectures, such as Sparc.
922 + Translate doubles to/from the x86 byte representation to ensure
923 cross-platform compatibility.
924 * ping plugin: Correct the handling of the `TTL' setting.
925 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
926 * swap plugin: Reapply a patch for Solaris.
927 * tcpconns plugin: Portability improvements.
929 2008-01-21, Version 4.2.4
930 * unixsock plugin: A bug in the unixsock plugin caused it not to set
931 the permission on the socket as documented in the manpage. Thanks to
932 Evgeny Chukreev for fixing this issue.
933 * collectd: The documentation has been improved.
935 2007-12-28, Version 4.2.3
936 * sensors plugin: Updated the plugin to build and work with version 3
937 of the libsensors library.
939 2007-12-15, Version 4.2.2
940 * nginx plugin: Incorrect comparison of strings lead to a segfault
941 when using the plugin. Thanks to Saulius Grigaliunas for fixing
943 * logfile plugin: The config option `Timestamp' was handled
944 incorrectly and basically always active. Thanks to Luke Heberling
947 2007-11-08, Version 4.2.1
948 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
950 * snmp plugin: Fix a memory leak.
952 2007-10-27, Version 4.2.0
953 * collectd: The new config option `Include' lets you include other
954 configfiles and thus split up your config into smaller parts. This
955 may be especially interesting for the snmp plugin to keep the data
956 definitions separate from the host definitions.
957 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
958 (number of connections, octets and packets for each service and
959 destination). Thanks to Sebastian Harl for this plugin.
960 * memcached plugin: The new `memcached' plugin connects to a memcached
961 daemon process and collects statistics of this distributed caching
962 system. Thanks to Antony Dovgal for contributing this plugin.
963 * nginx plugin: The new `nginx' plugin reads the status page of an
964 nginx daemon and saves the handled connections and requests.
965 * perl plugin: Many changes, including the added `EnableDebugger'
966 config option which lets you debug your Perl plugins more easily.
967 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
968 be more thread-safe otherwise by locking calls to the library.
969 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
970 correct the values returned by SNMP-agents. If a <data> block is
971 defined as `table' the instance is now optional. The sequence number
972 is used as the type-instance in this case. The new `InstancePrefix'
973 option allows to add arbitrary prefixes to the type-instance.
974 * tcpconns plugin: The new `tcpconns' plugin collects the number of
975 certain TCP connections and what state they're in. This can be used
976 to see how many connections your FTP server has to handle or how
977 many outgoing connections your mailserver has open.
979 2008-01-11, Version 4.1.6
980 * unixsock plugin: A bug in the unixsock plugin caused it not to set
981 the permission on the socket as documented in the manpage. Thanks to
982 Evgeny Chukreev for fixing this issue.
983 * collectd: The documentation has been improved.
985 2007-12-27, Version 4.1.5
986 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
988 * sensors plugin: Updated the plugin to build and work with version 3
989 of the libsensors library.
991 2007-11-08, Version 4.1.4
992 * Build system: Improve detection of the rrd library, especially if
993 it's in a non-standard location.
994 * Build system: A bug when parsing the argument for

1001 2007-10-24, Version 4.1.3
1002 * collectd: A build issue under Solaris has been resolved by renaming
1004 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1005 be more thread-safe otherwise by locking calls to the library.
1007 2007-09-28, Version 4.1.2
1008 * apcups plugin: Fix reporting of the `load percent' data.
1009 * wireless plugin: Correct the handling of cards returning signal and
1010 noise quality as percentage.

1030 whatever the client thinks is `now'..
1032 2007-09-01, Version 4.1.0
1033 * Build system: The build system has been changed to automatically
1034 disable all plugins, which are missing dependencies. The dependency
1035 checking has been removed from the plugins themselves to remove
1037 * Flexible interval: The interval of collected data is now sent along
1038 with the data itself over the network, so that the interval-settings
1039 of server and clients no longer needs to match.
1040 * netlink plugin: The new `netlink' plugin connects to the Linux
1041 kernel using a netlink socket and uses it to query information about
1042 interfaces, qdiscs and classes.
1043 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1044 to not block data collection.
1045 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1046 network devices, such as switches, routers, thermometers, rack

1061 with the broken GNU version of `strerror_r'.
1062 * collectd: Write an error message to STDERR when loading of a plugin
1064 * apcups plugin: Fix the `types' used to submit the values: They still
1065 has an `apcups_' prefix which doesn't work anymore.
1066 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1067 whatever the client thinks is `now'..
1069 2007-08-26, Version 4.0.7
1070 * documentation: Some typos have been fixed and some information has
1072 * build system: Many fixes for detecting libraries in unusual places,
1073 such as on RedHat systems. The affected libraries are `libcurl',
1074 `libmysql', and `libupsclient'.
1075 * network plugin: Allow the `Port' option to be specified as a number
1076 (i. e. without quotes).
1077 * nut plugin: A fix allows linking the nut plugin against
1078 libupsclient, version >= 2.2.0.
1079 * processes plugin: Fix a potential segmentation fault.
1081 2007-07-30, Version 4.0.6
1082 * sensors plugin: Fix the ignorelist functionality: Only the `type
1083 instance' was used to match against the list, but the documentation
1084 told otherwise. This release fixes the code, so it complies with the
1086 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1087 configuration messages will end up in the logging facility.
1088 * conrtib/fedora: The contributed specfile for Fedora has been
1091 2007-07-05, Version 4.0.5
1092 * Portability: More fixes for OpenBSD have been included.

1113 2007-06-07, Version 4.0.1
1114 * iptables plugin: A bug in the configuration routine has been fixed.
1115 Setting a comment in the configfile will no longer cause a
1118 2007-06-03, Version 4.0.0
1119 * collectd: The plugin-infrastructure has been changed to allow for
1120 more types of plugins, namely `write' and `log' plugins.
1121 * collectd: The read-function has been changed to read many plugins in
1122 parallel, using threads. Thus, plugins generally need to use
1123 thread-safe functions from now on.
1124 * collectd: The '-t' command line options allows to perform syntax tests
1125 of the configuration file and exit immediately.
1126 * csv plugin: The new `csv' plugin handles output to `comma separated
1128 * rrdtool plugin: The new `rrdtool' plugin handles output to
1129 RRD-files. Data can be cached to combine multiple updates into one
1130 write to increase IO-performance.
1131 * network plugin: The new `network' plugin handles IO via the network.
1132 It implements a different, much more extensible protocol which can
1133 combine many values in one packet, decreasing the number of UDP-
1134 packets being sent. It can read from and send to the network and
1135 with the appropriate configuration even forward packets to other
1137 * unixsock plugin: The new `unixsock' plugin provides an interface to
1138 communicate with the daemon while it is running. Right now the
1139 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1141 * perl plugin: The new `perl' plugin allows you to write extensions
1142 for collectd in the scripting-language Perl.
1143 * logfile plugin: The new `logfile' plugin writes logmessages to files
1144 or STDOUT or STDERR.
1145 * syslog plugin: The new `syslog' plugin sends logmessages to the
1146 system's syslog daemon.
1147 * entropy plugin: The new `entropy' plugin collects the amount of
1148 entropy currently being available to the system.
1149 * exec plugin: The new `exec' plugin forks child processes and reads
1150 back values provided by the forked processes.
1151 * iptables plugin: The new `iptables' plugin reads counters from
1152 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1154 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1155 to Peter Holik for contributing this plugin.
1156 * nut plugin: The new `nut' plugin connects the upsd of the `network
1157 ups tools' and reads information about the connected UPS.
1158 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1159 connections) field was added by Florent Monbillard.
1160 * collectd-nagios: The new `collectd-nagios' binary queries values
1161 from collectd, parses them and exits according to Nagios-standards.
1162 * manpages: The manpages have been improved a lot.
1164 2007-09-28, Version 3.11.7
1165 * wireless plugin: Correct the handling of cards returning signal and
1166 noise quality as percentage.
1168 2007-08-31, Version 3.11.6
1169 * processes plugin: Fix a potential segmentation fault.
1171 2007-05-29, Version 3.11.5
1172 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1173 * ntpd plugin: Fix a potential buffer overflow.
1174 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1175 were accounted as `zombies'.
1177 2007-04-10, Version 3.11.4
1178 * dns plugin: Change the order of includes to make the plugin compile
1181 2007-03-30, Version 3.11.3
1182 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1183 of the unused `COLLECT_KSTAT'.
1185 2007-02-11, Version 3.11.2
1186 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1187 NULL-pointer may have been passed to `printf' which causes a
1188 segfault with some libcs.
1190 2007-02-10, Version 3.11.1
1191 * df plugin: Some wrong defines have been fixed so the plugin works
1192 under Solaris again.
1193 * dns plugin: The usage of a struct has been fixed to work with
1195 * processes plugin: Some missing defines have been added so the plugin
1196 compiles cleanly under FreeBSD and presumably other UNIXes.
1198 2006-12-22, Version 3.11.0
1199 * collectd: The new command line option `-P' makes it easier for
1200 distributors to change the location of PID-files.
1201 * collectd: The daemon shuts down faster now which makes it easier to
1202 write init.d-scripts for it.
1203 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1204 caused problems every now and then.
1205 * df plugin: New config options allow to ignore certain mountpoints,
1206 filesystem types or devices.
1207 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1208 and interprets it. It collects traffic as well as qtype, opcode and
1210 * email plugin: Sebastian Harl has contributed this plugin which
1211 counts received mails in categories (e. g. ham, spam, virus), spam
1212 score (as given by SpamAssassin) and check types.
1213 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1214 uses `mbmon' to gather information from sensors on the motherboard.
1215 * processes plugin: Collect detailed statistics for configured
1216 processes, that's process and thread count, CPU usage, resident
1217 segment size and pagefaults.
1218 * multimeter plugin: Peter Holik contributed a new plugin which
1219 queries multimeters.
1220 * sensors plugin: Lubos Stanek has put much effort into improving this
1221 plugin, including `extended naming', collection of voltage values
1222 and the possibility to ignore certain values.
1224 2006-12-21, Version 3.10.4
1225 * Max Kellermann has identified a bug in the server routine: When
1226 opening a socket fails the daemon will (re)try opening the socket in
1227 an endless loop, ultimately leading to a `EMFILE' error.
1229 2006-11-04, Version 3.10.3
1230 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1231 ntpd's reply was sent in more than one packet, the buffer size was
1232 calculated incorrectly, resulting in the reading of uninitialized or
1235 2006-11-01, Version 3.10.2
1236 * The sample config file has been improved.
1237 * Errors in the manpages have been corrected.
1238 * The ping-plugin now adds hosts during initialization, not during
1239 startup. This speeds up startup when no network connectivity is
1240 available. Also, the hosts are being added later when the network is
1242 * Improved BSD-support for the df-plugin.
1243 * Fixed syntax errors in the swap-plugin for Mac OS X.
1244 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1246 * Don't disable the mysql-plugin if connecting to the database fails
1247 during initialization. Instead, try again in increasing intervals.
1249 2006-07-19, Version 3.10.1
1250 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1251 the apcups cannot be reached, unconnected sockets will pile up and
1252 eventually lead to `Too many open files' errors.
1254 2006-07-09, Version 3.10.0
1255 * The `disk' plugin has been ported to Darwin.
1256 * The `battery' plugin should work on many Apple computers now.
1257 * The `traffic' plugin can now ignore certain interfaces. Also,
1258 statistics for sent/received packets and errors have been added.
1259 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1260 to Anthony Gialluca for contributing this plugin and providing me
1261 with a test environment :)
1262 * A plugin for monitoring an NTP instance and the local clock drift
1265 2006-06-25, Version 3.9.4
1266 * The Solaris code in the `swap' plugin has been changed to reflect
1267 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1269 * The debugging system has been fixed to work with the Sun libc.
1270 * When built without librrd the variable `operating_mode' could be
1271 uninitialized. Thanks to David Elliot for reporting the bug.
1273 2006-06-01, Version 3.9.3
1274 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1275 operating systems also profit from the changes, but I wasn't able to
1277 * Changed the build system to find the netinet-includes under FreeBSD
1278 and therefore successfully build the `liboping' library there.
1280 2006-05-09, Version 3.9.2
1281 * Applied a patch to the `liboping' library. Due to a bug in the
1282 sequence checking the `ping' plugin stopped working after
1283 approximately 7.6 days.
1285 2006-05-09, Version 3.8.5
1286 * Applied a patch to the `liboping' library. Due to a bug in the
1287 sequence checking the `ping' plugin stopped working after
1288 approximately 7.6 days.
1290 2006-04-21, Version 3.9.1
1291 * Build issues with Solaris and possible other architectures have been
1293 * Problems when building the `apache'-plugin without `libcurl' have
1295 * A bug in the `ping' plugin has been fixed. Sorry folks.
1297 2006-04-02, Version 3.9.0
1298 * A plugin to monitor the Apache webserver has been added.
1299 <http://httpd.apache.org/>
1300 * A plugin to collect statistics about virtual servers using VServer.
1301 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1303 * A plugin for wireless LAN cards has been added. It monitors signal
1304 strength, link quality and noise ratio..
1305 * A plugin for Apple hardware sensors has been added.
1306 * An option to compile collectd with different `step' and `heartbeat'
1307 settings has been added. The size of RRAs is no longer static but
1308 calculated based on the settings for `step' and `width'.
1309 * The `ping' plugin can now be configured to use a certain TTL.
1310 * A plugin to monitor the hardware sensors of Apple computers has been
1312 * The plugins `cpu', `memory', `processes' and `traffic' have been
1313 ported to Mach/Darwin (Mac OS X).
1314 * The `log mode' has been contributed by Christophe Kalt. It writes
1315 the data into text files rather than RRD files.
1317 2006-04-09, Version 3.8.4
1318 * Applied patch by Vincent Stehlé which improves the disk-name
1319 resolution in the `hddtemp' plugin for Linux systems.
1321 2006-04-02, Version 3.8.3
1322 * Applied a patch by James Byers: The MySQL plugin was not working
1323 with MySQL 5.0.2 or later.
1325 2006-03-14, Version 3.8.2
1326 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1327 the GNU libc, because it points to `/etc/fstab' rather than
1330 2006-03-13, Version 3.8.1
1331 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1332 * Fixes in the debian `postinst' and `init.d' scripts.
1334 2006-03-09, Version 3.8.0
1335 * The `ping' plugin no longer uses `libping' but a self written
1336 library named `liboping'. With this library it's possible to ping
1337 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1339 2006-02-18, Version 3.7.2
1340 * A simple bug in the `battery' plugin has been fixed. It should now
1341 work with ACPI based batteries as well. Thanks to Sebastian for
1343 * Fixing a bug that prevented collectd to be built without librrd.
1344 Thanks to Werner Heuser for reporting it.
1346 2006-02-04, Version 3.7.1
1347 * The new network code has been improved to build with older versions
1349 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1350 to Tommie Gannert for this patch.
1352 2006-01-30, Version 3.7.0
1353 * The `battery' plugin has been added. It collects information about
1355 * The MySQL plugin has been improved: It now writes two more RRD
1356 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1357 * The `cpufreq' plugin now reads another file since the file it did
1358 read so far causes much overhead in the kernel. Also, you need root
1359 to read the old file, but not to read the new one.
1360 * The `hddtemp' plugin can now be configured to connect to another
1361 address and/or port than localhost.
1362 * The `df' plugin now prefers `statvfs' over `statfs'.
1363 * The network code has been rewritten. collectd now supports unicast
1364 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1365 be set in the configfile.
1367 2006-01-24, Version 3.6.2
1368 * Due to a bug in the configfile handling collectd wouldn't start in
1369 client mode. This released fixes this.
1371 2006-01-20, Version 3.6.1
1372 * Due to a bug in `configure.in' all modules and the binary were
1373 linked against `libmysqlclient'. This issue is solved by this
1376 2006-01-17, Version 3.6.0
1377 * A config file has been added. This allows for loading only specific
1379 * A `df' plugin has been added.
1380 * A `mysql' plugin has been added.
1381 * The `ping' plugin doesn't entirely give up hope when a socket error
1382 occurred, but will back of and increase the intervals between tries.
1384 2006-01-21, Version 3.5.2
1385 * Fixed yet another bug in the signal handling.. Stupid typo..
1386 * Improved the ping plugin to not give up on socket errors (backport
1389 2005-12-18, Version 3.5.1
1390 * The PID-file is now deleted correctly when shutting down the daemon.
1391 * SIGINT and SIGTERM are now handled correctly.
1393 2005-12-16, Version 3.5.0 (Revision 326)
1394 * A bug in the `load' module under Solaris has been fixed.
1395 * The `users' module has been contributed by Sebastian Harl. It counts
1396 currently logged in users.
1397 * The CPU module now works under FreeBSD without the use of
1398 `libstatgrab', however SMP support is missing.
1399 * The default directories for the RRD files and the PID file now
1400 depend on the compile time setting of `localstatedir'.
1402 2005-11-15, Version 3.4.0 (Revision 236)
1403 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1404 from gentoo's bugzilla for writing the patch.
1405 * The build dependency for librrd has been removed. Binaries built
1406 without librrd are client-only and will multicast their value as
1407 with the `-c' argument.
1408 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1409 * The newly introduced `-f' switch prevents daemon initialization
1410 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1411 Barcellos for this patch.
1413 2005-11-04, Version 3.3.0 (Revision 216)
1414 * New modules have been added:
1415 - `serial', for monitoring traffic on the serial interfaces
1416 - `nfs', for graphing NFS procedure calls
1417 - `tape', traffic from/to tape devices
1418 * The memory.rrd now accepts more than 4Gig of memory.
1420 2005-10-26, Version 3.2.0 (Revision 200)
1421 * Support for graphing the processes has been added (thanks to Lyonel

1424 between polls up to one day.
1425 * The init.d files have been improved.
1426 * Problems with the spec file have been fixed.
1428 2005-10-16, Version 3.1.0 (Revision 194)
1429 * Added the `setsid' syscall to the startup code.
1430 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1432 2005-09-30, Version 3.0.0 (Revision 184)
1433 * The ability to send/receive data to/from the network (think
1434 multicast) has been added.
1435 * Modules have been split up into shared libraries can be loaded at
1436 runtime. The biggest advantage is that the core program doesn't need
1437 to be linked against an external library.
1438 * A patch by George Kargiotakis has been applied: It fixes the sensors
1439 behaviour then more than one sensor is being queried.
1441 2005-09-16, Version 2.1.0 (Revision 172)
1442 * A module for swap statistics has been added.
1444 2005-09-09, Version 2.0.0 (Revision 135)
1445 * Filenames can no longer be configured at program startup. The only
1446 options as of this version are the directory and ping hosts.
1447 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1448 Soft-IRQ statistics are added to `System'.
1449 * Diskstats now collect read and write bytes, not sectors.
1450 * Ping statistics can now be collected for more than one host. There
1451 is no default any more: If no host is given no host will be pinged.
1452 * A self-written patch for libping has been applied so it builds
1455 2005-09-01, Version 1.8.1 (Revision 123)
1456 * Much improved configure-script: libraries and features may now be
1458 * More detailed warnings/error messages when RRD update fails.
1460 2005-08-29, Version 1.8.0:
1461 * Support for collecting disk statistics under Solaris.
1463 2005-08-25, Version 1.7.0:
1464 * Support for libstatgrab[1] for load, memory usage and network
1465 traffic. CPU- and disk-usage are not (yet) supported, since
1466 libstatgrab returns insufficient information. I will contact the
1468 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1469 aren't necessarily counted linear which is now handled correctly.
1470 [1]: http://www.i-scream.org/libstatgrab/
1472 2005-08-21, Version 1.6.0:
1473 * Basic support for Solaris: System load and cpu-usage can be
1474 collected under Solaris, too. Other stats will follow later.
1475 * Many fixes in the autoconf-script
1476 * Collection/Museum scripts have been added under contrib/museum
