491 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
492 to Alan Pevec for the patch.
493 * powerdns plugin: Set a timeout when reading data from the datagram
494 socket. Handling of the “LocalSocket” option has been fixed. An
495 incorrectly used “type” has been corrected. Thanks to Luke Heberling
498 2009-07-18, Version 4.6.4
499 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
500 Díaz for fixing this bug.
501 * collectd: A programming error has been fixed in the notification
502 code. The bug may result in an assertion failure.

504 for reporting the bug.
506 2009-06-02, Version 4.6.3
507 * Build system, various plugins: Many build fixes for FreeBSD,
508 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
509 for many fixes and providing a build system for many platforms,
510 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
511 providing an OpenBSD system.
512 * collectd: Two bugs with the threshold checking have been fixed. The
513 first one prevented thresholds to be checked at all, the second one
514 caused wrong behavior with the persistency option. Thanks to Andrés
515 J. Díaz for fixing these problems.
516 * collectd: Handling of the `Include' configuration option has been
518 * battery plugin: Don't complain about a missing directory every

532 * filter subsystem: Allow `Chains' without default targets.
533 * liboping: A patch to comply with strict aliasing rules has been
535 * timediff match: Fix a typo: The match was registered with a wrong
536 name which prevented this match to be used as documented. Thanks to
537 Bruno Prémont for finding this problem.
538 * bind plugin: Fix collection of the cached RR sets. The number of RR
539 sets currently in the cache was collected as a counter value, which
540 is nonsense. Thanks to Bruno Prémont for implementing this.
541 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
542 primarily BSDs, don't take it well and crash.
543 * oracle plugin: Portability to 64 bit systems has been improved.
544 * postgresql plugin: The default configuration has been improved.
545 * rrdtool plugin: Fix a possible race condition: If the network plugin
546 is brought and dispatches a value before the rrdtool plugin is
547 initialized, the daemon may crash.
549 2009-02-22, Version 4.6.1
550 * collectd: Many documentation fixes.
551 * Collectd::Unixsock: Error handling has been improved.

556 faults. Thanks to Peter Holik for his patch.
558 2009-02-16, Version 4.6.0
559 * collectd: Added the `filter chain' infrastructure, which allows the
560 user to use `matches' and `targets' to control value processing.
561 * collectd: The new `-T' command line argument allows more in-depth
562 testing of a configuration. Thanks to Doug MacEachern for the patch.
563 * collectd-nagios: The Nagios integration command has been updated to
564 use libcollectdclient. The `percentage' aggregation function has
565 been added. Thanks to Fabian Linzberger for the patch.
566 * libcollectdclient: A library which abstracts communication with the
567 unixsock plugin for clients has been added.
568 * regex match: Match values by their identifies using regular
570 * timediff match: Match for values with an invalid timestamp.
571 * value match: Select values by their data sources' values.
572 * notification target: Create and dispatch a notification.

577 statistics, allowing very detailed name server statistics. Thanks to
578 Bruno Prémont for this plugin.
579 * cpu plugin: Report `interrupt' separately when using
580 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
581 example for native OpenBSD support, has been added. Thanks to Simon
582 Kuhnle for the patch.
583 * csv plugin: Make it possible to write values to STDOUT instead of
584 files. This is meant for testing purposes mostly. The output written
585 to STDOUT is compatible with the exec plugin. Thanks to Doug
586 MacEachern for the patch.
587 * curl plugin: This new plugin can be used to read web pages and parse
588 them using the same mechanism that's used in the tail plugin.
589 * dbi plugin: This new plugin allows you to connect to a variety of
590 relational databases and use SQL to gather custom statistics from
591 it. It is similar to the already existing PostgreSQL plugin but uses
592 libdbi to communicate with the database(s).
593 * interface plugin: Use the ignorelist framework when selecting /
594 ignoring interfaces. This allows one to use regular expressions to
595 select interfaces, too.
596 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
597 Thanks to Bruno Prémont for this patch.
598 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
600 * mysql plugin: Allow connecting to a database via the UNIX domain
601 socket, too. Thanks to Mirko Buffoni for the patch.
602 * network plugin: Further performance improvements for the receive
603 code. This hopefully will help very large setups.
604 * openvpn plugin: This new plugin collects statistics provided by the
605 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
606 * oracle plugin: This new plugin allows you to connect to an Oracle
607 database and use SQL to gather custom statistics from it. It is
608 similar to the already existing PostgreSQL plugin.

611 * perl plugin: Export the newly added plugin_write() to Perl plugins.
612 * perl plugin: Added support for `notification meta data'.
613 * perl plugin: Added support for the `filter chain' infrastructure by
614 allowing plugins to register `matches' and `targets'.
615 * postgresql plugin: The preferred configuration syntax has been
616 updated to be in line with the syntax used by the new dbi and oracle
617 plugins. The compatibility code for the old syntax is present.
618 Support for the new `Result' blocks and the interval parameter has
620 * processes plugin: Stacksize and virtual memory usage statistics have
621 been added. Portability fixes.
622 * rrdcached plugin: This new plugin uses the (still in development)
623 RRD accelerator daemon, rrdcached. This daemon works very similar to
624 the original rrdtool plugin of collectd, but adds some more nice
626 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
629 2009-05-09, Version 4.5.4
630 * Build system, various plugins: Many build fixes for FreeBSD,
631 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

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

754 using Linux ACPI thermal zone data.
756 2009-01-02, Version 4.4.5
757 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
758 file may be in both locations, especially when the database was
759 installed in a non-standard path. Thanks to Dusty Doris for
761 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
762 Solaris, in the configure script automatically.
763 * collectd.conf(5): Various fixes and clarifications.
764 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
765 portability problems, especially for Solaris.
766 * dns plugin: Fix a portability problem with NetBSD.
767 * network plugin: Fix the handling of `type' in the network protocol.
768 Due to a programming mistake, only 4 or 8 bytes would be copied to a
769 much larger buffer. This caused the `type' to be transferred much
770 more often than necessary. In some cases, e. g. the `cpu' and
771 `cpufreq' plugins being used at the same time, data may be corrupted
772 in those files. Thanks to Bruno Prémont for debugging and reporting
774 * unixsock plugin: Make sure the initialization function is run only
775 once. This resolves a file descriptor leak under systems which run
776 the initialization more than once, such as Solaris.
778 2008-10-16, Version 4.4.4
779 * build system: Change `--enable-<plugin>' to abort with an error if
780 dependencies are not met. Thanks to Bruno Prémont for the patch.
781 Also, the poisoning of various string functions has been restricted

814 * dns plugin: Fix compilation errors with BIND versions 19991001
816 * network plugin: Bugfix in the init routine: The init function
817 cleared a buffer regardless of its contents. This could lead to lost
818 values under Solaris.
819 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
820 * vserver plugin: Remove usage of the thread-unsafe `readdir'
822 * wireless plugin: Work around incorrect noise and power values
823 returned by some broken drivers.
825 2008-06-03, Version 4.4.1
826 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
827 to kyrone for reporting this.
828 * collectd: Fixed min/max output in notifications generated by
830 * collectd-nagios: Fix the protocol used to communicate with the
832 * perl plugin: Fail noisily, but don't shutdown the daemon, if
833 initialization has errors. An issue with Perl 5.10 has been fixed.
834 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
835 René Rebe and Siegmund Gorr for reporting this.
837 2008-05-06, Version 4.4.0
838 * collectd: Internal code cleanups.
839 * collectd: Added support for a `Flush' command in the unixsock and
840 exec plugins. This command can be used to force a plugin (or all) to
841 flush its values to disk.
842 * collectd: Thresholds can now be configured to apply to one data
843 source only, making it possible to configure different thresholds
844 for each data source.

854 sensor values via IPMI, the intelligent platform management
856 * iptables plugin: The iptc library that is used by the iptables
857 plugin has been added to the distribution, because it is not
858 provided by all distributions and removed from at least one.
859 * powerdns plugin: The new powerdns plugin reads statistics from an
860 authoritative or a recursing PowerDNS name server.
861 * rrdtool plugin: The size of the files generated with the default
862 configuration has been decreased.
863 * tail plugin: The new tail plugin can be used to gather statistics by
864 continuously reading from log files.

866 TeamSpeak2 server and collects statistics about the number of users
867 and number of channels.
868 * users plugin: Support for the statgrab library has been added.
869 * vmem plugin: The new vmem plugin collects very detailed statistics
870 about the virtual memory subsystem of Linux.

915 * exec plugin: Set supplementary group IDs.
917 + Use `memcpy' when constructing/parsing a package to avoid
918 alignment problems on weird architectures, such as Sparc.
919 + Translate doubles to/from the x86 byte representation to ensure
920 cross-platform compatibility.
921 * ping plugin: Correct the handling of the `TTL' setting.
922 * swap plugin: Reapply a patch for Solaris.
923 * tcpconns plugin: Portability improvements.
925 2008-02-18, Version 4.3.0
926 * collectd: Notifications have been added to the daemon. Notifications
927 are status messages that may be associated with a data instance.
928 * collectd: Threshold checking has been added to the daemon. This
929 means that you can configure threshold values for each data
930 instance. If this threshold is exceeded a notification will be
932 * collectd: The new `FQDNLookup' option tells the daemon to use the
933 full qualified domain name as the hostname, not just the host part
934 es returned by `gethostname(2)'.
935 * collectd: Support for more than one `TypesDB' file has been added.
936 This is useful when one such file is included in a package but one
937 wants to add custom type definitions.
938 * collectd: The `Include' config option has been expanded to handle
939 entire directories and shell wildcards.
940 * collectdmon: The new `collectdmon' binary detects when collectd
941 terminates and automatically restarts it again.
942 * csv plugin: The CSV plugin is now able to store counter values as a
943 rate, using the `StoreRates' configuration option.
944 * exec plugin: Handling of notifications has been added and the
945 ability to pass arguments to the executed programs has been added.
946 * hddtemp plugin: The new `TranslateDevicename' option lets you
947 disable the translation from device names to major-minor-numbers.

949 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
950 domain name lookups in this plugin.
951 * perl plugin: Many internal changes added support for handling multiple
952 threads making the plugin reasonably usable inside collectd. The API has
953 been extended to support notifications and export global variables to
954 Perl plugins; callbacks now have to be identified by name rather than a
955 pointer to a subroutine. The plugin is no longer experimental.
956 * uuid plugin: The new UUID plugin sets the hostname to an unique
957 identifier for this host. This is meant for setups where each client
958 may migrate to another physical host, possibly going through one or
959 more name changes in the process. Thanks to Richard Jones from
960 Red Hat's Emerging Technology group for this plugin.
961 * libvirt: The new libvirt plugin uses the `libvirt' library to query
962 CPU, disk and network statistics about guest systems on the same
963 physical server. Thanks to Richard Jones from Red Hat's Emerging
964 Technology group for this plugin.
966 2008-04-22, Version 4.2.7
967 * build system: Improved detection of several libraries, especially if
968 they are in non-standard paths.

991 + Create separate threads for reading from the socket and parsing
992 and dispatching incoming packets. Versions prior to this may have
993 problems in high-load situations, where the socket receive buffers
994 overflows, resulting in gaps in the data.
995 + Use `memcpy' when constructing/parsing a package to avoid
996 alignment problems on weird architectures, such as Sparc.
997 + Translate doubles to/from the x86 byte representation to ensure
998 cross-platform compatibility.
999 * ping plugin: Correct the handling of the `TTL' setting.
1000 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1001 * swap plugin: Reapply a patch for Solaris.
1002 * tcpconns plugin: Portability improvements.
1004 2008-01-21, Version 4.2.4
1005 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1006 the permission on the socket as documented in the manpage. Thanks to
1007 Evgeny Chukreev for fixing this issue.
1008 * collectd: The documentation has been improved.
1010 2007-12-28, Version 4.2.3
1011 * sensors plugin: Updated the plugin to build and work with version 3
1012 of the libsensors library.
1014 2007-12-15, Version 4.2.2
1015 * nginx plugin: Incorrect comparison of strings lead to a segfault
1016 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1018 * logfile plugin: The config option `Timestamp' was handled
1019 incorrectly and basically always active. Thanks to Luke Heberling
1022 2007-11-08, Version 4.2.1
1023 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1024 enabled on the host.
1025 * snmp plugin: Fix a memory leak.
1027 2007-10-27, Version 4.2.0
1028 * collectd: The new config option `Include' lets you include other
1029 configfiles and thus split up your config into smaller parts. This
1030 may be especially interesting for the snmp plugin to keep the data
1031 definitions separate from the host definitions.
1032 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1033 (number of connections, octets and packets for each service and
1034 destination). Thanks to Sebastian Harl for this plugin.
1035 * memcached plugin: The new `memcached' plugin connects to a memcached
1036 daemon process and collects statistics of this distributed caching
1037 system. Thanks to Antony Dovgal for contributing this plugin.
1038 * nginx plugin: The new `nginx' plugin reads the status page of an
1039 nginx daemon and saves the handled connections and requests.
1040 * perl plugin: Many changes, including the added `EnableDebugger'
1041 config option which lets you debug your Perl plugins more easily.
1042 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1043 be more thread-safe otherwise by locking calls to the library.
1044 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1045 correct the values returned by SNMP-agents. If a <data> block is
1046 defined as `table' the instance is now optional. The sequence number
1047 is used as the type-instance in this case. The new `InstancePrefix'
1048 option allows to add arbitrary prefixes to the type-instance.
1049 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1050 certain TCP connections and what state they're in. This can be used
1051 to see how many connections your FTP server has to handle or how
1052 many outgoing connections your mailserver has open.
1054 2008-01-11, Version 4.1.6
1055 * unixsock plugin: A bug in the unixsock plugin caused it not to set

1058 * collectd: The documentation has been improved.
1060 2007-12-27, Version 4.1.5
1061 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1063 * sensors plugin: Updated the plugin to build and work with version 3
1064 of the libsensors library.
1066 2007-11-08, Version 4.1.4
1067 * Build system: Improve detection of the rrd library, especially if
1068 it's in a non-standard location.
1069 * Build system: A bug when parsing the argument for
1070 `--with-libnetsnmp' has been fixed.
1071 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1072 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1073 a deadlock or delay when shutting down the daemon.
1074 * snmp plugin: Fix a memory leak.
1076 2007-10-24, Version 4.1.3
1077 * collectd: A build issue under Solaris has been resolved by renaming
1079 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1080 be more thread-safe otherwise by locking calls to the library.
1082 2007-09-28, Version 4.1.2
1083 * apcups plugin: Fix reporting of the `load percent' data.
1084 * wireless plugin: Correct the handling of cards returning signal and
1085 noise quality as percentage.
1086 * perl plugin: Fix a possible buffer overflow in get_module_name().
1087 * build system: Further improve the detection of libraries.
1088 * netlink plugin: Build issues under some older versions of the Linux
1089 includes (i. e. Debian Sarge) have been fixed.
1090 * snmp plugin: Fix a potential segfault when a host times out. Add
1091 support for the `timeticks' type.
1093 2007-09-12, Version 4.1.1
1094 * Build system: The detection of `libnetlink' has been improved.
1095 * collectd: The documentation has been fixed in numerous places.
1096 * exec plugin: Setting the group under which to run a program has been
1098 * collectd: The `sstrerror' function was improved to work correctly
1099 with the broken GNU version of `strerror_r'.
1100 * collectd: Write an error message to STDERR when loading of a plugin
1102 * apcups plugin: Fix the `types' used to submit the values: They still
1103 has an `apcups_' prefix which doesn't work anymore.
1104 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1105 whatever the client thinks is `now'..
1107 2007-09-01, Version 4.1.0
1108 * Build system: The build system has been changed to automatically
1109 disable all plugins, which are missing dependencies. The dependency
1110 checking has been removed from the plugins themselves to remove
1112 * Flexible interval: The interval of collected data is now sent along
1113 with the data itself over the network, so that the interval-settings
1114 of server and clients no longer needs to match.
1115 * netlink plugin: The new `netlink' plugin connects to the Linux
1116 kernel using a netlink socket and uses it to query information about
1117 interfaces, qdiscs and classes.
1118 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1119 to not block data collection.
1120 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1121 network devices, such as switches, routers, thermometers, rack
1122 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1124 * unixsock plugin: Added the `LISTVAL' command.
1125 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1126 of music played with xmms.
1128 2007-09-28, Version 4.0.9
1129 * apcups plugin: Fix reporting of the `load percent' data.
1130 * wireless plugin: Correct the handling of cards returning signal and
1131 noise quality as percentage.
1132 * perl plugin: Fix a possible buffer overflow in get_module_name().
1134 2007-09-12, Version 4.0.8
1135 * collectd: The `sstrerror' function was improved to work correctly
1136 with the broken GNU version of `strerror_r'.
1137 * collectd: Write an error message to STDERR when loading of a plugin
1139 * apcups plugin: Fix the `types' used to submit the values: They still
1140 has an `apcups_' prefix which doesn't work anymore.
1141 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1142 whatever the client thinks is `now'..
1144 2007-08-26, Version 4.0.7
1145 * documentation: Some typos have been fixed and some information has
1147 * build system: Many fixes for detecting libraries in unusual places,
1148 such as on RedHat systems. The affected libraries are `libcurl',
1149 `libmysql', and `libupsclient'.
1150 * network plugin: Allow the `Port' option to be specified as a number
1151 (i. e. without quotes).
1152 * nut plugin: A fix allows linking the nut plugin against
1153 libupsclient, version >= 2.2.0.
1154 * processes plugin: Fix a potential segmentation fault.
1156 2007-07-30, Version 4.0.6
1157 * sensors plugin: Fix the ignorelist functionality: Only the `type
1158 instance' was used to match against the list, but the documentation
1159 told otherwise. This release fixes the code, so it complies with the
1161 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1162 configuration messages will end up in the logging facility.
1163 * conrtib/fedora: The contributed specfile for Fedora has been
1166 2007-07-05, Version 4.0.5
1167 * Portability: More fixes for OpenBSD have been included.
1169 2007-06-24, Version 4.0.4
1170 * cpu plugin: Fixed the Solaris code.
1171 * dns plugin: Fixed a build issue for OpenBSD.
1172 * interface plugin: Fixed the Solaris code.
1173 * load plugin: Fixed the alternative `/proc' Linux code.
1174 * memory plugin: Fixed the Solaris code.
1175 * oconfig: Don't require `-lfl' anymore.
1177 2007-06-19, Version 4.0.3
1178 * cpu plugin: Fix the Darwin / Mac OS X code.
1179 * ping plugin: Use the return value of `getpid', not its address.
1180 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1181 initialized correctly.
1182 * configure: Added `--with-nan-emulation' to aid cross compilation.
1184 2007-06-12, Version 4.0.2
1185 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1186 they're given in numerically form.
1188 2007-06-07, Version 4.0.1
1189 * iptables plugin: A bug in the configuration routine has been fixed.
1190 Setting a comment in the configfile will no longer cause a
1193 2007-06-03, Version 4.0.0
1194 * collectd: The plugin-infrastructure has been changed to allow for
1195 more types of plugins, namely `write' and `log' plugins.
1196 * collectd: The read-function has been changed to read many plugins in
1197 parallel, using threads. Thus, plugins generally need to use
1198 thread-safe functions from now on.
1199 * collectd: The '-t' command line options allows to perform syntax tests
1200 of the configuration file and exit immediately.
1201 * csv plugin: The new `csv' plugin handles output to `comma separated
1203 * rrdtool plugin: The new `rrdtool' plugin handles output to
1204 RRD-files. Data can be cached to combine multiple updates into one
1205 write to increase IO-performance.
1206 * network plugin: The new `network' plugin handles IO via the network.
1207 It implements a different, much more extensible protocol which can
1208 combine many values in one packet, decreasing the number of UDP-
1209 packets being sent. It can read from and send to the network and
1210 with the appropriate configuration even forward packets to other
1212 * unixsock plugin: The new `unixsock' plugin provides an interface to
1213 communicate with the daemon while it is running. Right now the
1214 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1216 * perl plugin: The new `perl' plugin allows you to write extensions
1217 for collectd in the scripting-language Perl.
1218 * logfile plugin: The new `logfile' plugin writes logmessages to files
1219 or STDOUT or STDERR.
1220 * syslog plugin: The new `syslog' plugin sends logmessages to the
1221 system's syslog daemon.
1222 * entropy plugin: The new `entropy' plugin collects the amount of
1223 entropy currently being available to the system.
1224 * exec plugin: The new `exec' plugin forks child processes and reads
1225 back values provided by the forked processes.
1226 * iptables plugin: The new `iptables' plugin reads counters from
1227 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1229 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1230 to Peter Holik for contributing this plugin.
1231 * nut plugin: The new `nut' plugin connects the upsd of the `network
1232 ups tools' and reads information about the connected UPS.
1233 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1234 connections) field was added by Florent Monbillard.
1235 * collectd-nagios: The new `collectd-nagios' binary queries values
1236 from collectd, parses them and exits according to Nagios-standards.
1237 * manpages: The manpages have been improved a lot.
1239 2007-09-28, Version 3.11.7
1240 * wireless plugin: Correct the handling of cards returning signal and
1241 noise quality as percentage.
1243 2007-08-31, Version 3.11.6
1244 * processes plugin: Fix a potential segmentation fault.
1246 2007-05-29, Version 3.11.5
1247 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1248 * ntpd plugin: Fix a potential buffer overflow.
1249 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1250 were accounted as `zombies'.
1252 2007-04-10, Version 3.11.4
1253 * dns plugin: Change the order of includes to make the plugin compile
1256 2007-03-30, Version 3.11.3
1257 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1258 of the unused `COLLECT_KSTAT'.
1260 2007-02-11, Version 3.11.2
1261 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1262 NULL-pointer may have been passed to `printf' which causes a
1263 segfault with some libcs.
1265 2007-02-10, Version 3.11.1
1266 * df plugin: Some wrong defines have been fixed so the plugin works
1267 under Solaris again.
1268 * dns plugin: The usage of a struct has been fixed to work with
1270 * processes plugin: Some missing defines have been added so the plugin
1271 compiles cleanly under FreeBSD and presumably other UNIXes.
1273 2006-12-22, Version 3.11.0
1274 * collectd: The new command line option `-P' makes it easier for
1275 distributors to change the location of PID-files.
1276 * collectd: The daemon shuts down faster now which makes it easier to
1277 write init.d-scripts for it.
1278 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1279 caused problems every now and then.
1280 * df plugin: New config options allow to ignore certain mountpoints,
1281 filesystem types or devices.
1282 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1283 and interprets it. It collects traffic as well as qtype, opcode and
1285 * email plugin: Sebastian Harl has contributed this plugin which
1286 counts received mails in categories (e. g. ham, spam, virus), spam
1287 score (as given by SpamAssassin) and check types.
1288 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1289 uses `mbmon' to gather information from sensors on the motherboard.
1290 * processes plugin: Collect detailed statistics for configured
1291 processes, that's process and thread count, CPU usage, resident
1292 segment size and pagefaults.
1293 * multimeter plugin: Peter Holik contributed a new plugin which
1294 queries multimeters.
1295 * sensors plugin: Lubos Stanek has put much effort into improving this
1296 plugin, including `extended naming', collection of voltage values
1297 and the possibility to ignore certain values.
1299 2006-12-21, Version 3.10.4
1300 * Max Kellermann has identified a bug in the server routine: When
1301 opening a socket fails the daemon will (re)try opening the socket in
1302 an endless loop, ultimately leading to a `EMFILE' error.
1304 2006-11-04, Version 3.10.3
1305 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1306 ntpd's reply was sent in more than one packet, the buffer size was
1307 calculated incorrectly, resulting in the reading of uninitialized or
1310 2006-11-01, Version 3.10.2
1311 * The sample config file has been improved.
1312 * Errors in the manpages have been corrected.
1313 * The ping-plugin now adds hosts during initialization, not during
1314 startup. This speeds up startup when no network connectivity is
1315 available. Also, the hosts are being added later when the network is
1317 * Improved BSD-support for the df-plugin.
1318 * Fixed syntax errors in the swap-plugin for Mac OS X.
1319 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1321 * Don't disable the mysql-plugin if connecting to the database fails
1322 during initialization. Instead, try again in increasing intervals.
1324 2006-07-19, Version 3.10.1
1325 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1326 the apcups cannot be reached, unconnected sockets will pile up and
1327 eventually lead to `Too many open files' errors.
1329 2006-07-09, Version 3.10.0
1330 * The `disk' plugin has been ported to Darwin.
1331 * The `battery' plugin should work on many Apple computers now.
1332 * The `traffic' plugin can now ignore certain interfaces. Also,
1333 statistics for sent/received packets and errors have been added.
1334 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1335 to Anthony Gialluca for contributing this plugin and providing me
1336 with a test environment :)
1337 * A plugin for monitoring an NTP instance and the local clock drift
1340 2006-06-25, Version 3.9.4
1341 * The Solaris code in the `swap' plugin has been changed to reflect
1342 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1344 * The debugging system has been fixed to work with the Sun libc.
1345 * When built without librrd the variable `operating_mode' could be
1346 uninitialized. Thanks to David Elliot for reporting the bug.
1348 2006-06-01, Version 3.9.3
1349 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1350 operating systems also profit from the changes, but I wasn't able to
1352 * Changed the build system to find the netinet-includes under FreeBSD
1353 and therefore successfully build the `liboping' library there.
1355 2006-05-09, Version 3.9.2
1356 * Applied a patch to the `liboping' library. Due to a bug in the
1357 sequence checking the `ping' plugin stopped working after
1358 approximately 7.6 days.
1360 2006-05-09, Version 3.8.5
1361 * Applied a patch to the `liboping' library. Due to a bug in the
1362 sequence checking the `ping' plugin stopped working after
1363 approximately 7.6 days.
1365 2006-04-21, Version 3.9.1
1366 * Build issues with Solaris and possible other architectures have been
1368 * Problems when building the `apache'-plugin without `libcurl' have
1370 * A bug in the `ping' plugin has been fixed. Sorry folks.
1372 2006-04-02, Version 3.9.0
1373 * A plugin to monitor the Apache webserver has been added.
1374 <http://httpd.apache.org/>
1375 * A plugin to collect statistics about virtual servers using VServer.
1376 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1378 * A plugin for wireless LAN cards has been added. It monitors signal
1379 strength, link quality and noise ratio..
1380 * A plugin for Apple hardware sensors has been added.
1381 * An option to compile collectd with different `step' and `heartbeat'
1382 settings has been added. The size of RRAs is no longer static but
1383 calculated based on the settings for `step' and `width'.
1384 * The `ping' plugin can now be configured to use a certain TTL.
1385 * A plugin to monitor the hardware sensors of Apple computers has been
1387 * The plugins `cpu', `memory', `processes' and `traffic' have been
1388 ported to Mach/Darwin (Mac OS X).
1389 * The `log mode' has been contributed by Christophe Kalt. It writes
1390 the data into text files rather than RRD files.
1392 2006-04-09, Version 3.8.4
1393 * Applied patch by Vincent Stehlé which improves the disk-name
1394 resolution in the `hddtemp' plugin for Linux systems.
1396 2006-04-02, Version 3.8.3
1397 * Applied a patch by James Byers: The MySQL plugin was not working
1398 with MySQL 5.0.2 or later.
1400 2006-03-14, Version 3.8.2
1401 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1402 the GNU libc, because it points to `/etc/fstab' rather than
1405 2006-03-13, Version 3.8.1
1406 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1407 * Fixes in the debian `postinst' and `init.d' scripts.
1409 2006-03-09, Version 3.8.0
1410 * The `ping' plugin no longer uses `libping' but a self written
1411 library named `liboping'. With this library it's possible to ping
1412 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1414 2006-02-18, Version 3.7.2
1415 * A simple bug in the `battery' plugin has been fixed. It should now
1416 work with ACPI based batteries as well. Thanks to Sebastian for
1418 * Fixing a bug that prevented collectd to be built without librrd.
1419 Thanks to Werner Heuser for reporting it.
1421 2006-02-04, Version 3.7.1
1422 * The new network code has been improved to build with older versions
1424 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1425 to Tommie Gannert for this patch.
1427 2006-01-30, Version 3.7.0
1428 * The `battery' plugin has been added. It collects information about
1430 * The MySQL plugin has been improved: It now writes two more RRD
1431 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1432 * The `cpufreq' plugin now reads another file since the file it did
1433 read so far causes much overhead in the kernel. Also, you need root
1434 to read the old file, but not to read the new one.
1435 * The `hddtemp' plugin can now be configured to connect to another
1436 address and/or port than localhost.
1437 * The `df' plugin now prefers `statvfs' over `statfs'.
1438 * The network code has been rewritten. collectd now supports unicast
1439 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1440 be set in the configfile.
1442 2006-01-24, Version 3.6.2
1443 * Due to a bug in the configfile handling collectd wouldn't start in
1444 client mode. This released fixes this.
1446 2006-01-20, Version 3.6.1
1447 * Due to a bug in `configure.in' all modules and the binary were
1448 linked against `libmysqlclient'. This issue is solved by this
1451 2006-01-17, Version 3.6.0
1452 * A config file has been added. This allows for loading only specific
1454 * A `df' plugin has been added.
1455 * A `mysql' plugin has been added.
1456 * The `ping' plugin doesn't entirely give up hope when a socket error
1457 occurred, but will back of and increase the intervals between tries.
1459 2006-01-21, Version 3.5.2
1460 * Fixed yet another bug in the signal handling.. Stupid typo..
1461 * Improved the ping plugin to not give up on socket errors (backport
1464 2005-12-18, Version 3.5.1
1465 * The PID-file is now deleted correctly when shutting down the daemon.
1466 * SIGINT and SIGTERM are now handled correctly.
1468 2005-12-16, Version 3.5.0 (Revision 326)
1469 * A bug in the `load' module under Solaris has been fixed.
1470 * The `users' module has been contributed by Sebastian Harl. It counts

1472 * The CPU module now works under FreeBSD without the use of
1473 `libstatgrab', however SMP support is missing.
1474 * The default directories for the RRD files and the PID file now
1475 depend on the compile time setting of `localstatedir'.
1477 2005-11-15, Version 3.4.0 (Revision 236)
1478 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1479 from gentoo's bugzilla for writing the patch.
1480 * The build dependency for librrd has been removed. Binaries built
1481 without librrd are client-only and will multicast their value as
1482 with the `-c' argument.
1483 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1484 * The newly introduced `-f' switch prevents daemon initialization
1485 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1486 Barcellos for this patch.
1488 2005-11-04, Version 3.3.0 (Revision 216)
1489 * New modules have been added:
1490 - `serial', for monitoring traffic on the serial interfaces
1491 - `nfs', for graphing NFS procedure calls
1492 - `tape', traffic from/to tape devices
1493 * The memory.rrd now accepts more than 4Gig of memory.
1495 2005-10-26, Version 3.2.0 (Revision 200)
1496 * Support for graphing the processes has been added (thanks to Lyonel
1498 * If reading from hddtemp fails collectd will increase the time
1499 between polls up to one day.
1500 * The init.d files have been improved.
1501 * Problems with the spec file have been fixed.
1503 2005-10-16, Version 3.1.0 (Revision 194)
1504 * Added the `setsid' syscall to the startup code.
1505 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1507 2005-09-30, Version 3.0.0 (Revision 184)
1508 * The ability to send/receive data to/from the network (think
1509 multicast) has been added.
1510 * Modules have been split up into shared libraries can be loaded at
1511 runtime. The biggest advantage is that the core program doesn't need
1512 to be linked against an external library.
1513 * A patch by George Kargiotakis has been applied: It fixes the sensors
1514 behaviour then more than one sensor is being queried.
1516 2005-09-16, Version 2.1.0 (Revision 172)
1517 * A module for swap statistics has been added.
1519 2005-09-09, Version 2.0.0 (Revision 135)
1520 * Filenames can no longer be configured at program startup. The only
1521 options as of this version are the directory and ping hosts.
1522 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1523 Soft-IRQ statistics are added to `System'.
1524 * Diskstats now collect read and write bytes, not sectors.
1525 * Ping statistics can now be collected for more than one host. There
1526 is no default any more: If no host is given no host will be pinged.
1527 * A self-written patch for libping has been applied so it builds
1530 2005-09-01, Version 1.8.1 (Revision 123)
1531 * Much improved configure-script: libraries and features may now be
1533 * More detailed warnings/error messages when RRD update fails.
1535 2005-08-29, Version 1.8.0:
1536 * Support for collecting disk statistics under Solaris.
1538 2005-08-25, Version 1.7.0:
1539 * Support for libstatgrab[1] for load, memory usage and network
1540 traffic. CPU- and disk-usage are not (yet) supported, since
1541 libstatgrab returns insufficient information. I will contact the
1543 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1544 aren't necessarily counted linear which is now handled correctly.
1545 [1]: http://www.i-scream.org/libstatgrab/
1547 2005-08-21, Version 1.6.0:
1548 * Basic support for Solaris: System load and cpu-usage can be
1549 collected under Solaris, too. Other stats will follow later.
1550 * Many fixes in the autoconf-script
1551 * Collection/Museum scripts have been added under contrib/museum
1552 * collectd may now be started in unprivileged mode, though ping
1553 statistics will not work.
1555 2005-07-17, Version 1.5.1:
1556 * Diskstats-RRDs now use major/minor for naming. Some systems have
1557 weird strings as disk-names..
1559 2005-07-17, Version 1.5:
1560 * A new module, diskstats, has been added. It collects information
1561 about the disks and partitions.
1563 2005-07-11, Version 1.4.2:
1564 * The meminfo module has been changed to work with more platforms
1565 and/or kernel versions.
1567 2005-07-10, Version 1.4.1: Correct traffic stats
1568 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1569 forgot to correct when I changed that module.
1571 2005-07-09, Version 1.4: More traffic stats
1572 * Traffic is now collected for all interfaces that can be found
1573 * Temperature-statistics are read from lm-sensors if available
1575 2005-07-08, Version 1.3: CPU stats
1576 * Collecting CPU statistics now
1578 2005-07-12, Version 1.2: Using syslog
1579 * collectd is now using the syslog facility to report errors, warnings
1581 * The default directory is now /var/db/collectd
1583 2005-07-10, Version 1.1: Minor changes
1584 * Nothing really useful to say ;)
1586 2005-07-09, Version 1.0: Initial Version
1587 * The following modules are provided:
