505 * filter subsystem: Allow `Chains' without default targets.
506 * liboping: A patch to comply with strict aliasing rules has been
508 * timediff match: Fix a typo: The match was registered with a wrong
509 name which prevented this match to be used as documented. Thanks to
510 Bruno Prémont for finding this problem.
511 * bind plugin: Fix collection of the cached RR sets. The number of RR
512 sets currently in the cache was collected as a counter value, which
513 is nonsense. Thanks to Bruno Prémont for implementing this.
514 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
515 primarily BSDs, don't take it well and crash.
516 * oracle plugin: Portability to 64 bit systems has been improved.
517 * postgresql plugin: The default configuration has been improved.
518 * rrdtool plugin: Fix a possible race condition: If the network plugin
519 is brought and dispatches a value before the rrdtool plugin is
520 initialized, the daemon may crash.
522 2009-02-22, Version 4.6.1
523 * collectd: Many documentation fixes.
524 * Collectd::Unixsock: Error handling has been improved.

526 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
527 for finding and fixing most of them.
528 * ipmi plugin: Fix an off-by-one error which could cause segmentation
529 faults. Thanks to Peter Holik for his patch.
531 2009-02-16, Version 4.6.0
532 * collectd: Added the `filter chain' infrastructure, which allows the
533 user to use `matches' and `targets' to control value processing.
534 * collectd: The new `-T' command line argument allows more in-depth
535 testing of a configuration. Thanks to Doug MacEachern for the patch.
536 * collectd-nagios: The Nagios integration command has been updated to
537 use libcollectdclient. The `percentage' aggregation function has
538 been added. Thanks to Fabian Linzberger for the patch.
539 * libcollectdclient: A library which abstracts communication with the
540 unixsock plugin for clients has been added.
541 * regex match: Match values by their identifies using regular
543 * timediff match: Match for values with an invalid timestamp.
544 * value match: Select values by their data sources' values.
545 * notification target: Create and dispatch a notification.
546 * replace target: Replace parts of an identifier using regular
548 * set target: Set (overwrite) entire parts of an identifier.
549 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
550 statistics, allowing very detailed name server statistics. Thanks to
551 Bruno Prémont for this plugin.
552 * cpu plugin: Report `interrupt' separately when using
553 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
554 example for native OpenBSD support, has been added. Thanks to Simon
555 Kuhnle for the patch.
556 * csv plugin: Make it possible to write values to STDOUT instead of
557 files. This is meant for testing purposes mostly. The output written
558 to STDOUT is compatible with the exec plugin. Thanks to Doug
559 MacEachern for the patch.
560 * curl plugin: This new plugin can be used to read web pages and parse
561 them using the same mechanism that's used in the tail plugin.
562 * dbi plugin: This new plugin allows you to connect to a variety of
563 relational databases and use SQL to gather custom statistics from
564 it. It is similar to the already existing PostgreSQL plugin but uses
565 libdbi to communicate with the database(s).
566 * interface plugin: Use the ignorelist framework when selecting /
567 ignoring interfaces. This allows one to use regular expressions to
568 select interfaces, too.
569 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
570 Thanks to Bruno Prémont for this patch.
571 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
573 * mysql plugin: Allow connecting to a database via the UNIX domain
574 socket, too. Thanks to Mirko Buffoni for the patch.
575 * network plugin: Further performance improvements for the receive
576 code. This hopefully will help very large setups.
577 * openvpn plugin: This new plugin collects statistics provided by the
578 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
579 * oracle plugin: This new plugin allows you to connect to an Oracle
580 database and use SQL to gather custom statistics from it. It is
581 similar to the already existing PostgreSQL plugin.
582 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
584 * perl plugin: Export the newly added plugin_write() to Perl plugins.
585 * perl plugin: Added support for `notification meta data'.
586 * perl plugin: Added support for the `filter chain' infrastructure by
587 allowing plugins to register `matches' and `targets'.
588 * postgresql plugin: The preferred configuration syntax has been
589 updated to be in line with the syntax used by the new dbi and oracle
590 plugins. The compatibility code for the old syntax is present.
591 Support for the new `Result' blocks and the interval parameter has
593 * processes plugin: Stacksize and virtual memory usage statistics have
594 been added. Portability fixes.
595 * rrdcached plugin: This new plugin uses the (still in development)
596 RRD accelerator daemon, rrdcached. This daemon works very similar to
597 the original rrdtool plugin of collectd, but adds some more nice
599 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
602 2009-05-09, Version 4.5.4
603 * Build system, various plugins: Many build fixes for FreeBSD,
604 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
605 for many fixes and providing a build system for many platforms,
606 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
607 providing an OpenBSD system.

615 Tomasz Pala for the patch.
616 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
618 * rrdtool plugin: Fix a possible race condition: If the network plugin
619 is initialized and dispatches a value before the rrdtool plugin is
620 initialized, the daemon may crash.
621 * memory plugin: Fix a potential problem under Solaris.
623 2009-02-22, Version 4.5.3
624 * build system: The check for libupsclient even when `pkg-config' is
626 * collectd: Fix error handling in the global cache.
627 * Collectd::Unixsock: Error handling has been improved.
628 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
630 * ipmi plugin: Fix an off-by-one error which could cause segmentation
631 faults. Thanks to Peter Holik for his patch.
632 * tcpconns plugin: An endianness problem has been fixed in the *BSD
633 code. Thanks to "thated" for reporting this.
635 2009-01-02, Version 4.5.2
636 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
637 file may be in both locations, especially when the database was
638 installed in a non-standard path. Thanks to Dusty Doris for
640 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
641 Solaris, in the configure script automatically.
642 * build system, tcpconns plugin: Check for `kvm_nlist' and
643 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
644 library with similar functions to the BSD variant, but doesn't
645 provide these necessary functions.
646 * collectd.conf(5): Various fixes and clarifications.
647 * collectd: Remove a GNUism (unnamed unions), thus improving
649 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
650 This solves portability problems, especially for Solaris.
651 * dns plugin: Fix a portability problem with NetBSD.
652 * filecount plugin: Fix an off-by-one error. This error may cause a
654 * network plugin: Fix the handling of `type' in the network protocol.
655 Due to a programming mistake, only 4 or 8 bytes would be copied to a
656 much larger buffer. This caused the `type' to be transferred much
657 more often than necessary. In some cases, e. g. the `cpu' and
658 `cpufreq' plugins being used at the same time, data may be corrupted
659 in those files. Thanks to Bruno Prémont for debugging and reporting
661 * processes plugin: Fix a possible segmentation fault when specifying
662 invalid configuration options.
663 * unixsock plugin: Make sure the initialization function is run only
664 once. This resolves a file descriptor leak under systems which run
665 the initialization more than once, such as Solaris.
667 2008-10-16, Version 4.5.1
668 * build system: Change `--enable-<plugin>' to abort with an error if
669 dependencies are not met. Thanks to Bruno Prémont for the patch.
670 Also, the poisoning of various string functions has been restricted
672 * collectd: Fix a memory leak in the global value cache. With every
673 *missing* value a couple of bytes would be leaked. Another memory
674 leak in the configuration handling code has been fixed. Thanks to
675 Niraj Tolia for reporting these issues.
676 * collectd: Fix an off-by-one error in the ignorelist functionality.
677 When using regular expressions, the last character would be missing,
678 possibly matching differently from what one would expect.
679 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
681 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
682 Linzberger for reporting the bug.
683 * iptables plugin: Fix an off-by-one error. If a string was just one
684 character too long, it was truncated instead of reporting an error.
685 * network plugin: Fix a memory leak in the configuration handling
686 code. Thanks to Niraj Tolia for reporting this issue.
687 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
688 * postgresql plugin: Don't reopen connection during reinitialization.
689 This fixes a bug under Solaris and potentially other platforms.
690 Missing calls to `PQclear' have been added, too. This fixes memory
691 leaks. Thanks to ``Admin'' for reporting these bugs.
692 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
694 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
695 problems with some `libc's. Thanks to Matthias Lay for reporting the
698 2008-09-04, Version 4.5.0
699 * collectd: Added the ability to flush certain identifiers.
700 * collectd: The concept of `notification meta data' has been
702 * filecount plugin: The new filecount plugin counts the number of
703 files in a directory and its subdirectories.
704 * ipmi plugin: Sensor names have been changed to ensure unique names.
705 Notifications upon added and removed sensors can now be generated.
706 * notify_desktop plugin: This new plugin sends notifications to the
707 X desktop using the structure defined in the `Desktop Notification
709 * notify_email plugin: This new plugin sends out notifications via
710 email, using the `esmtp' library.
711 * onewire plugin: The new experimental(!) onewire plugin reads values,
712 such as temperatures, from sensors connected to the computer via the
714 * perl plugin: Improved synchronized access to internal data structures
715 and fixed a possible dead-lock.
716 * perl plugin: Added the ability to flush certain identifiers and marked
717 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
719 * perl plugin: Added the ability to configure Perl plugins.
720 * postgresql plugin: The new postgresql plugin collects statistics
721 about or from a PostgreSQL database.
722 * processes plugin: The `ProcessMatch' option has been added.
723 * rrdtool plugin: Implement throttling of the `update queue' to lessen
725 * tcpconns plugin: This plugin has been ported to OpenBSD.

727 using Linux ACPI thermal zone data.
729 2009-01-02, Version 4.4.5
730 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
731 file may be in both locations, especially when the database was
732 installed in a non-standard path. Thanks to Dusty Doris for
734 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
735 Solaris, in the configure script automatically.
736 * collectd.conf(5): Various fixes and clarifications.
737 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
738 portability problems, especially for Solaris.
739 * dns plugin: Fix a portability problem with NetBSD.
740 * network plugin: Fix the handling of `type' in the network protocol.
741 Due to a programming mistake, only 4 or 8 bytes would be copied to a
742 much larger buffer. This caused the `type' to be transferred much
743 more often than necessary. In some cases, e. g. the `cpu' and
744 `cpufreq' plugins being used at the same time, data may be corrupted
745 in those files. Thanks to Bruno Prémont for debugging and reporting
747 * unixsock plugin: Make sure the initialization function is run only
748 once. This resolves a file descriptor leak under systems which run
749 the initialization more than once, such as Solaris.
751 2008-10-16, Version 4.4.4
752 * build system: Change `--enable-<plugin>' to abort with an error if
753 dependencies are not met. Thanks to Bruno Prémont for the patch.
754 Also, the poisoning of various string functions has been restricted
756 * collectd: Fix a memory leak in the global value cache. With every

787 * dns plugin: Fix compilation errors with BIND versions 19991001
789 * network plugin: Bugfix in the init routine: The init function
790 cleared a buffer regardless of its contents. This could lead to lost
791 values under Solaris.
792 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
793 * vserver plugin: Remove usage of the thread-unsafe `readdir'
795 * wireless plugin: Work around incorrect noise and power values
796 returned by some broken drivers.

799 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
800 to kyrone for reporting this.
801 * collectd: Fixed min/max output in notifications generated by
803 * collectd-nagios: Fix the protocol used to communicate with the
805 * perl plugin: Fail noisily, but don't shutdown the daemon, if
806 initialization has errors. An issue with Perl 5.10 has been fixed.
807 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
808 René Rebe and Siegmund Gorr for reporting this.
810 2008-05-06, Version 4.4.0
811 * collectd: Internal code cleanups.
812 * collectd: Added support for a `Flush' command in the unixsock and
813 exec plugins. This command can be used to force a plugin (or all) to
814 flush its values to disk.
815 * collectd: Thresholds can now be configured to apply to one data
816 source only, making it possible to configure different thresholds
817 for each data source.
818 * apache, nginx plugins: Added the possibility to disable host and/or
820 * ascent plugin: The new ascent plugin reads and parses the statistics
821 page of an Ascent server.

827 sensor values via IPMI, the intelligent platform management
829 * iptables plugin: The iptc library that is used by the iptables
830 plugin has been added to the distribution, because it is not
831 provided by all distributions and removed from at least one.
832 * powerdns plugin: The new powerdns plugin reads statistics from an
833 authoritative or a recursing PowerDNS name server.
834 * rrdtool plugin: The size of the files generated with the default
835 configuration has been decreased.
836 * tail plugin: The new tail plugin can be used to gather statistics by
837 continuously reading from log files.
838 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
839 TeamSpeak2 server and collects statistics about the number of users
840 and number of channels.
841 * users plugin: Support for the statgrab library has been added.
842 * vmem plugin: The new vmem plugin collects very detailed statistics
843 about the virtual memory subsystem of Linux.

865 they are in non-standard paths.
866 * build system: Portability fixes: Automatically define "_REENTRANT"
867 if the libc expects it.
868 * collectd: Error and warning messages have been improved.
869 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
871 * apache plugin: Allocate new memory when reading a webpage instead of
872 using a buffer of static size.
873 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
875 * hddtemp plugin: Error and warning messages have been improved.
876 * sensors plugin: Fix sensor collection for some chip types.
878 2008-03-29, Version 4.3.2

887 2008-03-05, Version 4.3.1
888 * exec plugin: Set supplementary group IDs.
890 + Use `memcpy' when constructing/parsing a package to avoid
891 alignment problems on weird architectures, such as Sparc.
892 + Translate doubles to/from the x86 byte representation to ensure
893 cross-platform compatibility.
894 * ping plugin: Correct the handling of the `TTL' setting.
895 * swap plugin: Reapply a patch for Solaris.
896 * tcpconns plugin: Portability improvements.
898 2008-02-18, Version 4.3.0
899 * collectd: Notifications have been added to the daemon. Notifications
900 are status messages that may be associated with a data instance.
901 * collectd: Threshold checking has been added to the daemon. This
902 means that you can configure threshold values for each data
903 instance. If this threshold is exceeded a notification will be
905 * collectd: The new `FQDNLookup' option tells the daemon to use the
906 full qualified domain name as the hostname, not just the host part
907 es returned by `gethostname(2)'.
908 * collectd: Support for more than one `TypesDB' file has been added.
909 This is useful when one such file is included in a package but one
910 wants to add custom type definitions.
911 * collectd: The `Include' config option has been expanded to handle
912 entire directories and shell wildcards.
913 * collectdmon: The new `collectdmon' binary detects when collectd
914 terminates and automatically restarts it again.
915 * csv plugin: The CSV plugin is now able to store counter values as a
916 rate, using the `StoreRates' configuration option.
917 * exec plugin: Handling of notifications has been added and the
918 ability to pass arguments to the executed programs has been added.
919 * hddtemp plugin: The new `TranslateDevicename' option lets you
920 disable the translation from device names to major-minor-numbers.
921 * logfile plugin: Handling of notifications has been added.
922 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
923 domain name lookups in this plugin.
924 * perl plugin: Many internal changes added support for handling multiple
925 threads making the plugin reasonably usable inside collectd. The API has
926 been extended to support notifications and export global variables to
927 Perl plugins; callbacks now have to be identified by name rather than a
928 pointer to a subroutine. The plugin is no longer experimental.
929 * uuid plugin: The new UUID plugin sets the hostname to an unique
930 identifier for this host. This is meant for setups where each client
931 may migrate to another physical host, possibly going through one or
932 more name changes in the process. Thanks to Richard Jones from
933 Red Hat's Emerging Technology group for this plugin.
934 * libvirt: The new libvirt plugin uses the `libvirt' library to query
935 CPU, disk and network statistics about guest systems on the same
936 physical server. Thanks to Richard Jones from Red Hat's Emerging
937 Technology group for this plugin.
939 2008-04-22, Version 4.2.7
940 * build system: Improved detection of several libraries, especially if
941 they are in non-standard paths.

943 if the libc expects it.
944 * collectd: Error and warning messages have been improved.
945 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
947 * apache plugin: Allocate new memory when reading a webpage instead of
948 using a buffer of static size.
949 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
951 * hddtemp plugin: Error and warning messages have been improved.

960 2008-03-04, Version 4.2.5
961 * apache plugin: Improved initialization and error messages.
962 * exec plugin: Set supplementary group IDs.
964 + Create separate threads for reading from the socket and parsing
965 and dispatching incoming packets. Versions prior to this may have
966 problems in high-load situations, where the socket receive buffers
967 overflows, resulting in gaps in the data.
968 + Use `memcpy' when constructing/parsing a package to avoid
969 alignment problems on weird architectures, such as Sparc.
970 + Translate doubles to/from the x86 byte representation to ensure
971 cross-platform compatibility.
972 * ping plugin: Correct the handling of the `TTL' setting.
973 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
974 * swap plugin: Reapply a patch for Solaris.
975 * tcpconns plugin: Portability improvements.
977 2008-01-21, Version 4.2.4

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 2007-12-28, Version 4.2.3
984 * sensors plugin: Updated the plugin to build and work with version 3
985 of the libsensors library.
987 2007-12-15, Version 4.2.2
988 * nginx plugin: Incorrect comparison of strings lead to a segfault
989 when using the plugin. Thanks to Saulius Grigaliunas for fixing
991 * logfile plugin: The config option `Timestamp' was handled
992 incorrectly and basically always active. Thanks to Luke Heberling
995 2007-11-08, Version 4.2.1
996 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
998 * snmp plugin: Fix a memory leak.
1000 2007-10-27, Version 4.2.0
1001 * collectd: The new config option `Include' lets you include other
1002 configfiles and thus split up your config into smaller parts. This
1003 may be especially interesting for the snmp plugin to keep the data
1004 definitions separate from the host definitions.
1005 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1006 (number of connections, octets and packets for each service and
1007 destination). Thanks to Sebastian Harl for this plugin.
1008 * memcached plugin: The new `memcached' plugin connects to a memcached
1009 daemon process and collects statistics of this distributed caching
1010 system. Thanks to Antony Dovgal for contributing this plugin.
1011 * nginx plugin: The new `nginx' plugin reads the status page of an
1012 nginx daemon and saves the handled connections and requests.
1013 * perl plugin: Many changes, including the added `EnableDebugger'
1014 config option which lets you debug your Perl plugins more easily.
1015 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1016 be more thread-safe otherwise by locking calls to the library.
1017 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1018 correct the values returned by SNMP-agents. If a <data> block is
1019 defined as `table' the instance is now optional. The sequence number
1020 is used as the type-instance in this case. The new `InstancePrefix'
1021 option allows to add arbitrary prefixes to the type-instance.
1022 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1023 certain TCP connections and what state they're in. This can be used
1024 to see how many connections your FTP server has to handle or how
1025 many outgoing connections your mailserver has open.
1027 2008-01-11, Version 4.1.6
1028 * unixsock plugin: A bug in the unixsock plugin caused it not to set

1037 of the libsensors library.
1039 2007-11-08, Version 4.1.4
1040 * Build system: Improve detection of the rrd library, especially if
1041 it's in a non-standard location.
1042 * Build system: A bug when parsing the argument for
1043 `--with-libnetsnmp' has been fixed.
1044 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1045 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1046 a deadlock or delay when shutting down the daemon.
1047 * snmp plugin: Fix a memory leak.
1049 2007-10-24, Version 4.1.3
1050 * collectd: A build issue under Solaris has been resolved by renaming
1052 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1053 be more thread-safe otherwise by locking calls to the library.
1055 2007-09-28, Version 4.1.2
1056 * apcups plugin: Fix reporting of the `load percent' data.
1057 * wireless plugin: Correct the handling of cards returning signal and
1058 noise quality as percentage.
1059 * perl plugin: Fix a possible buffer overflow in get_module_name().
1060 * build system: Further improve the detection of libraries.
1061 * netlink plugin: Build issues under some older versions of the Linux
1062 includes (i. e. Debian Sarge) have been fixed.
1063 * snmp plugin: Fix a potential segfault when a host times out. Add
1064 support for the `timeticks' type.
1066 2007-09-12, Version 4.1.1
1067 * Build system: The detection of `libnetlink' has been improved.
1068 * collectd: The documentation has been fixed in numerous places.
1069 * exec plugin: Setting the group under which to run a program has been
1071 * collectd: The `sstrerror' function was improved to work correctly
1072 with the broken GNU version of `strerror_r'.
1073 * collectd: Write an error message to STDERR when loading of a plugin
1075 * apcups plugin: Fix the `types' used to submit the values: They still
1076 has an `apcups_' prefix which doesn't work anymore.
1077 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1078 whatever the client thinks is `now'..
1080 2007-09-01, Version 4.1.0
1081 * Build system: The build system has been changed to automatically
1082 disable all plugins, which are missing dependencies. The dependency
1083 checking has been removed from the plugins themselves to remove
1085 * Flexible interval: The interval of collected data is now sent along
1086 with the data itself over the network, so that the interval-settings
1087 of server and clients no longer needs to match.
1088 * netlink plugin: The new `netlink' plugin connects to the Linux
1089 kernel using a netlink socket and uses it to query information about
1090 interfaces, qdiscs and classes.
1091 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1092 to not block data collection.
1093 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1094 network devices, such as switches, routers, thermometers, rack
1095 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1097 * unixsock plugin: Added the `LISTVAL' command.
1098 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1099 of music played with xmms.
1101 2007-09-28, Version 4.0.9
1102 * apcups plugin: Fix reporting of the `load percent' data.
1103 * wireless plugin: Correct the handling of cards returning signal and
1104 noise quality as percentage.
1105 * perl plugin: Fix a possible buffer overflow in get_module_name().
1107 2007-09-12, Version 4.0.8
1108 * collectd: The `sstrerror' function was improved to work correctly
1109 with the broken GNU version of `strerror_r'.
1110 * collectd: Write an error message to STDERR when loading of a plugin
1112 * apcups plugin: Fix the `types' used to submit the values: They still
1113 has an `apcups_' prefix which doesn't work anymore.
1114 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1115 whatever the client thinks is `now'..
1117 2007-08-26, Version 4.0.7
1118 * documentation: Some typos have been fixed and some information has
1120 * build system: Many fixes for detecting libraries in unusual places,
1121 such as on RedHat systems. The affected libraries are `libcurl',
1122 `libmysql', and `libupsclient'.
1123 * network plugin: Allow the `Port' option to be specified as a number
1124 (i. e. without quotes).
1125 * nut plugin: A fix allows linking the nut plugin against
1126 libupsclient, version >= 2.2.0.
1127 * processes plugin: Fix a potential segmentation fault.
1129 2007-07-30, Version 4.0.6
1130 * sensors plugin: Fix the ignorelist functionality: Only the `type
1131 instance' was used to match against the list, but the documentation
1132 told otherwise. This release fixes the code, so it complies with the
1134 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1135 configuration messages will end up in the logging facility.
1136 * conrtib/fedora: The contributed specfile for Fedora has been
1139 2007-07-05, Version 4.0.5
1140 * Portability: More fixes for OpenBSD have been included.
1142 2007-06-24, Version 4.0.4

1159 they're given in numerically form.
1161 2007-06-07, Version 4.0.1
1162 * iptables plugin: A bug in the configuration routine has been fixed.
1163 Setting a comment in the configfile will no longer cause a
1166 2007-06-03, Version 4.0.0
1167 * collectd: The plugin-infrastructure has been changed to allow for
1168 more types of plugins, namely `write' and `log' plugins.
1169 * collectd: The read-function has been changed to read many plugins in
1170 parallel, using threads. Thus, plugins generally need to use
1171 thread-safe functions from now on.
1172 * collectd: The '-t' command line options allows to perform syntax tests
1173 of the configuration file and exit immediately.
1174 * csv plugin: The new `csv' plugin handles output to `comma separated
1176 * rrdtool plugin: The new `rrdtool' plugin handles output to
1177 RRD-files. Data can be cached to combine multiple updates into one
1178 write to increase IO-performance.
1179 * network plugin: The new `network' plugin handles IO via the network.
1180 It implements a different, much more extensible protocol which can
1181 combine many values in one packet, decreasing the number of UDP-
1182 packets being sent. It can read from and send to the network and
1183 with the appropriate configuration even forward packets to other
1185 * unixsock plugin: The new `unixsock' plugin provides an interface to
1186 communicate with the daemon while it is running. Right now the
1187 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1189 * perl plugin: The new `perl' plugin allows you to write extensions
1190 for collectd in the scripting-language Perl.
1191 * logfile plugin: The new `logfile' plugin writes logmessages to files
1192 or STDOUT or STDERR.
1193 * syslog plugin: The new `syslog' plugin sends logmessages to the
1194 system's syslog daemon.
1195 * entropy plugin: The new `entropy' plugin collects the amount of
1196 entropy currently being available to the system.
1197 * exec plugin: The new `exec' plugin forks child processes and reads
1198 back values provided by the forked processes.
1199 * iptables plugin: The new `iptables' plugin reads counters from
1200 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1202 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1203 to Peter Holik for contributing this plugin.
1204 * nut plugin: The new `nut' plugin connects the upsd of the `network
1205 ups tools' and reads information about the connected UPS.
1206 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1207 connections) field was added by Florent Monbillard.
1208 * collectd-nagios: The new `collectd-nagios' binary queries values
1209 from collectd, parses them and exits according to Nagios-standards.
1210 * manpages: The manpages have been improved a lot.
1212 2007-09-28, Version 3.11.7
1213 * wireless plugin: Correct the handling of cards returning signal and
1214 noise quality as percentage.
1216 2007-08-31, Version 3.11.6

1219 2007-05-29, Version 3.11.5
1220 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1221 * ntpd plugin: Fix a potential buffer overflow.
1222 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1223 were accounted as `zombies'.
1225 2007-04-10, Version 3.11.4
1226 * dns plugin: Change the order of includes to make the plugin compile
1229 2007-03-30, Version 3.11.3
1230 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1231 of the unused `COLLECT_KSTAT'.
1233 2007-02-11, Version 3.11.2
1234 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1235 NULL-pointer may have been passed to `printf' which causes a
1236 segfault with some libcs.
1238 2007-02-10, Version 3.11.1
1239 * df plugin: Some wrong defines have been fixed so the plugin works
1240 under Solaris again.
1241 * dns plugin: The usage of a struct has been fixed to work with
1243 * processes plugin: Some missing defines have been added so the plugin
1244 compiles cleanly under FreeBSD and presumably other UNIXes.
1246 2006-12-22, Version 3.11.0
1247 * collectd: The new command line option `-P' makes it easier for
1248 distributors to change the location of PID-files.
1249 * collectd: The daemon shuts down faster now which makes it easier to
1250 write init.d-scripts for it.
1251 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1252 caused problems every now and then.
1253 * df plugin: New config options allow to ignore certain mountpoints,
1254 filesystem types or devices.
1255 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1256 and interprets it. It collects traffic as well as qtype, opcode and
1258 * email plugin: Sebastian Harl has contributed this plugin which
1259 counts received mails in categories (e. g. ham, spam, virus), spam
1260 score (as given by SpamAssassin) and check types.
1261 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1262 uses `mbmon' to gather information from sensors on the motherboard.
1263 * processes plugin: Collect detailed statistics for configured
1264 processes, that's process and thread count, CPU usage, resident
1265 segment size and pagefaults.
1266 * multimeter plugin: Peter Holik contributed a new plugin which
1267 queries multimeters.
1268 * sensors plugin: Lubos Stanek has put much effort into improving this
1269 plugin, including `extended naming', collection of voltage values
1270 and the possibility to ignore certain values.
1272 2006-12-21, Version 3.10.4
1273 * Max Kellermann has identified a bug in the server routine: When
1274 opening a socket fails the daemon will (re)try opening the socket in
1275 an endless loop, ultimately leading to a `EMFILE' error.
1277 2006-11-04, Version 3.10.3
1278 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1279 ntpd's reply was sent in more than one packet, the buffer size was
1280 calculated incorrectly, resulting in the reading of uninitialized or
1283 2006-11-01, Version 3.10.2
1284 * The sample config file has been improved.
1285 * Errors in the manpages have been corrected.
1286 * The ping-plugin now adds hosts during initialization, not during
1287 startup. This speeds up startup when no network connectivity is
1288 available. Also, the hosts are being added later when the network is
1290 * Improved BSD-support for the df-plugin.
1291 * Fixed syntax errors in the swap-plugin for Mac OS X.
1292 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1294 * Don't disable the mysql-plugin if connecting to the database fails
1295 during initialization. Instead, try again in increasing intervals.
1297 2006-07-19, Version 3.10.1
1298 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1299 the apcups cannot be reached, unconnected sockets will pile up and
1300 eventually lead to `Too many open files' errors.
1302 2006-07-09, Version 3.10.0
1303 * The `disk' plugin has been ported to Darwin.
1304 * The `battery' plugin should work on many Apple computers now.
1305 * The `traffic' plugin can now ignore certain interfaces. Also,
1306 statistics for sent/received packets and errors have been added.
1307 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1308 to Anthony Gialluca for contributing this plugin and providing me
1309 with a test environment :)
1310 * A plugin for monitoring an NTP instance and the local clock drift
1313 2006-06-25, Version 3.9.4
1314 * The Solaris code in the `swap' plugin has been changed to reflect
1315 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1317 * The debugging system has been fixed to work with the Sun libc.
1318 * When built without librrd the variable `operating_mode' could be
1319 uninitialized. Thanks to David Elliot for reporting the bug.
1321 2006-06-01, Version 3.9.3
1322 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1323 operating systems also profit from the changes, but I wasn't able to
1325 * Changed the build system to find the netinet-includes under FreeBSD
1326 and therefore successfully build the `liboping' library there.
1328 2006-05-09, Version 3.9.2
1329 * Applied a patch to the `liboping' library. Due to a bug in the
1330 sequence checking the `ping' plugin stopped working after
1331 approximately 7.6 days.
1333 2006-05-09, Version 3.8.5
1334 * Applied a patch to the `liboping' library. Due to a bug in the
1335 sequence checking the `ping' plugin stopped working after
1336 approximately 7.6 days.
1338 2006-04-21, Version 3.9.1
1339 * Build issues with Solaris and possible other architectures have been
1341 * Problems when building the `apache'-plugin without `libcurl' have
1343 * A bug in the `ping' plugin has been fixed. Sorry folks.
1345 2006-04-02, Version 3.9.0
1346 * A plugin to monitor the Apache webserver has been added.
1347 <http://httpd.apache.org/>
1348 * A plugin to collect statistics about virtual servers using VServer.
1349 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1351 * A plugin for wireless LAN cards has been added. It monitors signal
1352 strength, link quality and noise ratio..
1353 * A plugin for Apple hardware sensors has been added.
1354 * An option to compile collectd with different `step' and `heartbeat'
1355 settings has been added. The size of RRAs is no longer static but
1356 calculated based on the settings for `step' and `width'.
1357 * The `ping' plugin can now be configured to use a certain TTL.
1358 * A plugin to monitor the hardware sensors of Apple computers has been
1360 * The plugins `cpu', `memory', `processes' and `traffic' have been
1361 ported to Mach/Darwin (Mac OS X).
1362 * The `log mode' has been contributed by Christophe Kalt. It writes
1363 the data into text files rather than RRD files.
1365 2006-04-09, Version 3.8.4
1366 * Applied patch by Vincent Stehlé which improves the disk-name
1367 resolution in the `hddtemp' plugin for Linux systems.
1369 2006-04-02, Version 3.8.3
1370 * Applied a patch by James Byers: The MySQL plugin was not working
1371 with MySQL 5.0.2 or later.
1373 2006-03-14, Version 3.8.2
1374 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1375 the GNU libc, because it points to `/etc/fstab' rather than
1378 2006-03-13, Version 3.8.1
1379 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1380 * Fixes in the debian `postinst' and `init.d' scripts.
1382 2006-03-09, Version 3.8.0
1383 * The `ping' plugin no longer uses `libping' but a self written
1384 library named `liboping'. With this library it's possible to ping
1385 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1387 2006-02-18, Version 3.7.2
1388 * A simple bug in the `battery' plugin has been fixed. It should now
1389 work with ACPI based batteries as well. Thanks to Sebastian for
1391 * Fixing a bug that prevented collectd to be built without librrd.
1392 Thanks to Werner Heuser for reporting it.
1394 2006-02-04, Version 3.7.1
1395 * The new network code has been improved to build with older versions
1397 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1398 to Tommie Gannert for this patch.
1400 2006-01-30, Version 3.7.0
1401 * The `battery' plugin has been added. It collects information about
1403 * The MySQL plugin has been improved: It now writes two more RRD
1404 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1405 * The `cpufreq' plugin now reads another file since the file it did
1406 read so far causes much overhead in the kernel. Also, you need root
1407 to read the old file, but not to read the new one.
1408 * The `hddtemp' plugin can now be configured to connect to another
1409 address and/or port than localhost.
1410 * The `df' plugin now prefers `statvfs' over `statfs'.
1411 * The network code has been rewritten. collectd now supports unicast
1412 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1413 be set in the configfile.
1415 2006-01-24, Version 3.6.2
1416 * Due to a bug in the configfile handling collectd wouldn't start in
1417 client mode. This released fixes this.
1419 2006-01-20, Version 3.6.1
1420 * Due to a bug in `configure.in' all modules and the binary were
1421 linked against `libmysqlclient'. This issue is solved by this
1424 2006-01-17, Version 3.6.0
1425 * A config file has been added. This allows for loading only specific
1427 * A `df' plugin has been added.
1428 * A `mysql' plugin has been added.
1429 * The `ping' plugin doesn't entirely give up hope when a socket error
1430 occurred, but will back of and increase the intervals between tries.
1432 2006-01-21, Version 3.5.2
1433 * Fixed yet another bug in the signal handling.. Stupid typo..
1434 * Improved the ping plugin to not give up on socket errors (backport
1437 2005-12-18, Version 3.5.1
1438 * The PID-file is now deleted correctly when shutting down the daemon.
1439 * SIGINT and SIGTERM are now handled correctly.
1441 2005-12-16, Version 3.5.0 (Revision 326)
1442 * A bug in the `load' module under Solaris has been fixed.
1443 * The `users' module has been contributed by Sebastian Harl. It counts
1444 currently logged in users.
1445 * The CPU module now works under FreeBSD without the use of
1446 `libstatgrab', however SMP support is missing.
1447 * The default directories for the RRD files and the PID file now
1448 depend on the compile time setting of `localstatedir'.
1450 2005-11-15, Version 3.4.0 (Revision 236)
1451 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1452 from gentoo's bugzilla for writing the patch.
1453 * The build dependency for librrd has been removed. Binaries built
1454 without librrd are client-only and will multicast their value as
1455 with the `-c' argument.
1456 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1457 * The newly introduced `-f' switch prevents daemon initialization
1458 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1459 Barcellos for this patch.
1461 2005-11-04, Version 3.3.0 (Revision 216)
1462 * New modules have been added:
1463 - `serial', for monitoring traffic on the serial interfaces
1464 - `nfs', for graphing NFS procedure calls
1465 - `tape', traffic from/to tape devices
1466 * The memory.rrd now accepts more than 4Gig of memory.
1468 2005-10-26, Version 3.2.0 (Revision 200)
1469 * Support for graphing the processes has been added (thanks to Lyonel
1471 * If reading from hddtemp fails collectd will increase the time
1472 between polls up to one day.
1473 * The init.d files have been improved.
1474 * Problems with the spec file have been fixed.
1476 2005-10-16, Version 3.1.0 (Revision 194)
1477 * Added the `setsid' syscall to the startup code.
1478 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1480 2005-09-30, Version 3.0.0 (Revision 184)
1481 * The ability to send/receive data to/from the network (think
1482 multicast) has been added.
1483 * Modules have been split up into shared libraries can be loaded at
1484 runtime. The biggest advantage is that the core program doesn't need
1485 to be linked against an external library.
1486 * A patch by George Kargiotakis has been applied: It fixes the sensors
1487 behaviour then more than one sensor is being queried.
1489 2005-09-16, Version 2.1.0 (Revision 172)
1490 * A module for swap statistics has been added.
1492 2005-09-09, Version 2.0.0 (Revision 135)
1493 * Filenames can no longer be configured at program startup. The only
1494 options as of this version are the directory and ping hosts.
1495 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1496 Soft-IRQ statistics are added to `System'.
1497 * Diskstats now collect read and write bytes, not sectors.
1498 * Ping statistics can now be collected for more than one host. There
1499 is no default any more: If no host is given no host will be pinged.
1500 * A self-written patch for libping has been applied so it builds
1503 2005-09-01, Version 1.8.1 (Revision 123)
1504 * Much improved configure-script: libraries and features may now be
1506 * More detailed warnings/error messages when RRD update fails.
1508 2005-08-29, Version 1.8.0:
1509 * Support for collecting disk statistics under Solaris.
1511 2005-08-25, Version 1.7.0:
1512 * Support for libstatgrab[1] for load, memory usage and network
1513 traffic. CPU- and disk-usage are not (yet) supported, since
1514 libstatgrab returns insufficient information. I will contact the
1516 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1517 aren't necessarily counted linear which is now handled correctly.
1518 [1]: http://www.i-scream.org/libstatgrab/
1520 2005-08-21, Version 1.6.0:
1521 * Basic support for Solaris: System load and cpu-usage can be
1522 collected under Solaris, too. Other stats will follow later.
1523 * Many fixes in the autoconf-script
1524 * Collection/Museum scripts have been added under contrib/museum
1525 * collectd may now be started in unprivileged mode, though ping
1526 statistics will not work.
1528 2005-07-17, Version 1.5.1:
1529 * Diskstats-RRDs now use major/minor for naming. Some systems have
1530 weird strings as disk-names..
1532 2005-07-17, Version 1.5:
1533 * A new module, diskstats, has been added. It collects information
1534 about the disks and partitions.
1536 2005-07-11, Version 1.4.2:
1537 * The meminfo module has been changed to work with more platforms
1538 and/or kernel versions.
1540 2005-07-10, Version 1.4.1: Correct traffic stats
1541 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1542 forgot to correct when I changed that module.
1544 2005-07-09, Version 1.4: More traffic stats
1545 * Traffic is now collected for all interfaces that can be found
1546 * Temperature-statistics are read from lm-sensors if available
1548 2005-07-08, Version 1.3: CPU stats
1549 * Collecting CPU statistics now
1551 2005-07-12, Version 1.2: Using syslog
1552 * collectd is now using the syslog facility to report errors, warnings
1554 * The default directory is now /var/db/collectd
1556 2005-07-10, Version 1.1: Minor changes
1557 * Nothing really useful to say ;)
1559 2005-07-09, Version 1.0: Initial Version
1560 * The following modules are provided:
