494 primarily BSDs, don't take it well and crash.
495 * oracle plugin: Portability to 64 bit systems has been improved.
496 * postgresql plugin: The default configuration has been improved.
497 * rrdtool plugin: Fix a possible race condition: If the network plugin
498 is brought and dispatches a value before the rrdtool plugin is
499 initialized, the daemon may crash.
501 2009-02-22, Version 4.6.1
502 * collectd: Many documentation fixes.
503 * Collectd::Unixsock: Error handling has been improved.
504 * regex match: Don't link with the PCRE library.
505 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
506 for finding and fixing most of them.
507 * ipmi plugin: Fix an off-by-one error which could cause segmentation
508 faults. Thanks to Peter Holik for his patch.
510 2009-02-16, Version 4.6.0
511 * collectd: Added the `filter chain' infrastructure, which allows the
512 user to use `matches' and `targets' to control value processing.
513 * collectd: The new `-T' command line argument allows more in-depth
514 testing of a configuration. Thanks to Doug MacEachern for the patch.
515 * collectd-nagios: The Nagios integration command has been updated to
516 use libcollectdclient. The `percentage' aggregation function has
517 been added. Thanks to Fabian Linzberger for the patch.
518 * libcollectdclient: A library which abstracts communication with the
519 unixsock plugin for clients has been added.
520 * regex match: Match values by their identifies using regular
522 * timediff match: Match for values with an invalid timestamp.
523 * value match: Select values by their data sources' values.
524 * notification target: Create and dispatch a notification.
525 * replace target: Replace parts of an identifier using regular
527 * set target: Set (overwrite) entire parts of an identifier.
528 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
529 statistics, allowing very detailed name server statistics. Thanks to
530 Bruno Prémont for this plugin.
531 * cpu plugin: Report `interrupt' separately when using
532 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
533 example for native OpenBSD support, has been added. Thanks to Simon
534 Kuhnle for the patch.
535 * csv plugin: Make it possible to write values to STDOUT instead of
536 files. This is meant for testing purposes mostly. The output written
537 to STDOUT is compatible with the exec plugin. Thanks to Doug
538 MacEachern for the patch.
539 * curl plugin: This new plugin can be used to read web pages and parse
540 them using the same mechanism that's used in the tail plugin.
541 * dbi plugin: This new plugin allows you to connect to a variety of
542 relational databases and use SQL to gather custom statistics from
543 it. It is similar to the already existing PostgreSQL plugin but uses
544 libdbi to communicate with the database(s).
545 * interface plugin: Use the ignorelist framework when selecting /
546 ignoring interfaces. This allows one to use regular expressions to
547 select interfaces, too.
548 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
549 Thanks to Bruno Prémont for this patch.
550 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
552 * mysql plugin: Allow connecting to a database via the UNIX domain
553 socket, too. Thanks to Mirko Buffoni for the patch.
554 * network plugin: Further performance improvements for the receive
555 code. This hopefully will help very large setups.
556 * openvpn plugin: This new plugin collects statistics provided by the
557 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
558 * oracle plugin: This new plugin allows you to connect to an Oracle
559 database and use SQL to gather custom statistics from it. It is
560 similar to the already existing PostgreSQL plugin.
561 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
563 * perl plugin: Export the newly added plugin_write() to Perl plugins.
564 * perl plugin: Added support for `notification meta data'.
565 * perl plugin: Added support for the `filter chain' infrastructure by
566 allowing plugins to register `matches' and `targets'.
567 * postgresql plugin: The preferred configuration syntax has been
568 updated to be in line with the syntax used by the new dbi and oracle
569 plugins. The compatibility code for the old syntax is present.
570 Support for the new `Result' blocks and the interval parameter has
572 * processes plugin: Stacksize and virtual memory usage statistics have
573 been added. Portability fixes.
574 * rrdcached plugin: This new plugin uses the (still in development)
575 RRD accelerator daemon, rrdcached. This daemon works very similar to
576 the original rrdtool plugin of collectd, but adds some more nice
578 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
581 2009-05-09, Version 4.5.4
582 * Build system, various plugins: Many build fixes for FreeBSD,
583 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
584 for many fixes and providing a build system for many platforms,
585 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
586 providing an OpenBSD system.
587 * collectd: Fix a potential race condition when creating directories.
588 * battery plugin: Don't complain about a missing directory every
590 * dns plugin: Slight portability fixes.
591 * exec plugin: Allow executed programs to close STDERR. Thanks to
592 Thorsten von Eicken for reporting this problem.
593 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
594 Tomasz Pala for the patch.
595 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
597 * rrdtool plugin: Fix a possible race condition: If the network plugin
598 is initialized and dispatches a value before the rrdtool plugin is
599 initialized, the daemon may crash.
600 * memory plugin: Fix a potential problem under Solaris.
602 2009-02-22, Version 4.5.3
603 * build system: The check for libupsclient even when `pkg-config' is
605 * collectd: Fix error handling in the global cache.
606 * Collectd::Unixsock: Error handling has been improved.
607 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
609 * ipmi plugin: Fix an off-by-one error which could cause segmentation
610 faults. Thanks to Peter Holik for his patch.
611 * tcpconns plugin: An endianness problem has been fixed in the *BSD
612 code. Thanks to "thated" for reporting this.
614 2009-01-02, Version 4.5.2
615 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
616 file may be in both locations, especially when the database was
617 installed in a non-standard path. Thanks to Dusty Doris for
619 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
620 Solaris, in the configure script automatically.
621 * build system, tcpconns plugin: Check for `kvm_nlist' and
622 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
623 library with similar functions to the BSD variant, but doesn't
624 provide these necessary functions.
625 * collectd.conf(5): Various fixes and clarifications.
626 * collectd: Remove a GNUism (unnamed unions), thus improving
628 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
629 This solves portability problems, especially for Solaris.
630 * dns plugin: Fix a portability problem with NetBSD.
631 * filecount plugin: Fix an off-by-one error. This error may cause a
633 * network plugin: Fix the handling of `type' in the network protocol.
634 Due to a programming mistake, only 4 or 8 bytes would be copied to a
635 much larger buffer. This caused the `type' to be transferred much
636 more often than necessary. In some cases, e. g. the `cpu' and
637 `cpufreq' plugins being used at the same time, data may be corrupted
638 in those files. Thanks to Bruno Prémont for debugging and reporting
640 * processes plugin: Fix a possible segmentation fault when specifying
641 invalid configuration options.
642 * unixsock plugin: Make sure the initialization function is run only
643 once. This resolves a file descriptor leak under systems which run
644 the initialization more than once, such as Solaris.
646 2008-10-16, Version 4.5.1
647 * build system: Change `--enable-<plugin>' to abort with an error if
648 dependencies are not met. Thanks to Bruno Prémont for the patch.
649 Also, the poisoning of various string functions has been restricted
651 * collectd: Fix a memory leak in the global value cache. With every
652 *missing* value a couple of bytes would be leaked. Another memory
653 leak in the configuration handling code has been fixed. Thanks to
654 Niraj Tolia for reporting these issues.
655 * collectd: Fix an off-by-one error in the ignorelist functionality.
656 When using regular expressions, the last character would be missing,
657 possibly matching differently from what one would expect.
658 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
660 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
661 Linzberger for reporting the bug.
662 * iptables plugin: Fix an off-by-one error. If a string was just one
663 character too long, it was truncated instead of reporting an error.
664 * network plugin: Fix a memory leak in the configuration handling
665 code. Thanks to Niraj Tolia for reporting this issue.
666 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
667 * postgresql plugin: Don't reopen connection during reinitialization.
668 This fixes a bug under Solaris and potentially other platforms.
669 Missing calls to `PQclear' have been added, too. This fixes memory
670 leaks. Thanks to ``Admin'' for reporting these bugs.
671 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
673 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
674 problems with some `libc's. Thanks to Matthias Lay for reporting the
677 2008-09-04, Version 4.5.0
678 * collectd: Added the ability to flush certain identifiers.
679 * collectd: The concept of `notification meta data' has been
681 * filecount plugin: The new filecount plugin counts the number of
682 files in a directory and its subdirectories.
683 * ipmi plugin: Sensor names have been changed to ensure unique names.
684 Notifications upon added and removed sensors can now be generated.
685 * notify_desktop plugin: This new plugin sends notifications to the
686 X desktop using the structure defined in the `Desktop Notification
688 * notify_email plugin: This new plugin sends out notifications via
689 email, using the `esmtp' library.
690 * onewire plugin: The new experimental(!) onewire plugin reads values,
691 such as temperatures, from sensors connected to the computer via the
693 * perl plugin: Improved synchronized access to internal data structures
694 and fixed a possible dead-lock.
695 * perl plugin: Added the ability to flush certain identifiers and marked
696 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
698 * perl plugin: Added the ability to configure Perl plugins.
699 * postgresql plugin: The new postgresql plugin collects statistics
700 about or from a PostgreSQL database.
701 * processes plugin: The `ProcessMatch' option has been added.
702 * rrdtool plugin: Implement throttling of the `update queue' to lessen
704 * tcpconns plugin: This plugin has been ported to OpenBSD.
705 * thermal plugin: The new thermal plugin collects system temperatures
706 using Linux ACPI thermal zone data.
708 2009-01-02, Version 4.4.5
709 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
710 file may be in both locations, especially when the database was
711 installed in a non-standard path. Thanks to Dusty Doris for
713 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
714 Solaris, in the configure script automatically.
715 * collectd.conf(5): Various fixes and clarifications.
716 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
717 portability problems, especially for Solaris.
718 * dns plugin: Fix a portability problem with NetBSD.
719 * network plugin: Fix the handling of `type' in the network protocol.
720 Due to a programming mistake, only 4 or 8 bytes would be copied to a
721 much larger buffer. This caused the `type' to be transferred much
722 more often than necessary. In some cases, e. g. the `cpu' and
723 `cpufreq' plugins being used at the same time, data may be corrupted
724 in those files. Thanks to Bruno Prémont for debugging and reporting
726 * unixsock plugin: Make sure the initialization function is run only
727 once. This resolves a file descriptor leak under systems which run
728 the initialization more than once, such as Solaris.
730 2008-10-16, Version 4.4.4
731 * build system: Change `--enable-<plugin>' to abort with an error if
732 dependencies are not met. Thanks to Bruno Prémont for the patch.
733 Also, the poisoning of various string functions has been restricted
735 * collectd: Fix a memory leak in the global value cache. With every
736 *missing* value a couple of bytes would be leaked. Another memory
737 leak in the configuration handling code has been fixed. Thanks to
738 Niraj Tolia for reporting these issues.
739 * collectd: Fix an off-by-one error in the ignorelist functionality.
740 When using regular expressions, the last character would be missing,
741 possibly matching differently from what one would expect.
742 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
744 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
745 Linzberger for reporting the bug.
746 * network plugin: Fix a memory leak in the configuration handling
747 code. Thanks to Niraj Tolia for reporting this issue.
748 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
749 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
750 problems with some `libc's. Thanks to Matthias Lay for reporting the
753 2008-09-01, Version 4.4.3
754 * collectd: Fix a memory leak in the threshold checking code.
755 * memcached plugin: Fix a too short timeout and a related file

762 * collectd: Try even harder to determine the endianess of the
763 architecture collectd is being built on.
764 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
766 * dns plugin: Fix compilation errors with BIND versions 19991001
768 * network plugin: Bugfix in the init routine: The init function
769 cleared a buffer regardless of its contents. This could lead to lost
770 values under Solaris.
771 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
772 * vserver plugin: Remove usage of the thread-unsafe `readdir'
774 * wireless plugin: Work around incorrect noise and power values
775 returned by some broken drivers.
777 2008-06-03, Version 4.4.1
778 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
779 to kyrone for reporting this.
780 * collectd: Fixed min/max output in notifications generated by
782 * collectd-nagios: Fix the protocol used to communicate with the
784 * perl plugin: Fail noisily, but don't shutdown the daemon, if
785 initialization has errors. An issue with Perl 5.10 has been fixed.
786 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
787 René Rebe and Siegmund Gorr for reporting this.
789 2008-05-06, Version 4.4.0
790 * collectd: Internal code cleanups.
791 * collectd: Added support for a `Flush' command in the unixsock and
792 exec plugins. This command can be used to force a plugin (or all) to
793 flush its values to disk.
794 * collectd: Thresholds can now be configured to apply to one data
795 source only, making it possible to configure different thresholds
796 for each data source.

802 * disk plugin: The possibility to ignore certain disks or collect only
803 specific disks has been added.
804 * disk plugin: Support for the statgrab library has been added.
805 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
806 sensor values via IPMI, the intelligent platform management
808 * iptables plugin: The iptc library that is used by the iptables
809 plugin has been added to the distribution, because it is not
810 provided by all distributions and removed from at least one.
811 * powerdns plugin: The new powerdns plugin reads statistics from an
812 authoritative or a recursing PowerDNS name server.
813 * rrdtool plugin: The size of the files generated with the default
814 configuration has been decreased.
815 * tail plugin: The new tail plugin can be used to gather statistics by
816 continuously reading from log files.
817 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
818 TeamSpeak2 server and collects statistics about the number of users
819 and number of channels.
820 * users plugin: Support for the statgrab library has been added.
821 * vmem plugin: The new vmem plugin collects very detailed statistics
822 about the virtual memory subsystem of Linux.

843 * build system: Improved detection of several libraries, especially if
844 they are in non-standard paths.
845 * build system: Portability fixes: Automatically define "_REENTRANT"
846 if the libc expects it.
847 * collectd: Error and warning messages have been improved.
848 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
850 * apache plugin: Allocate new memory when reading a webpage instead of
851 using a buffer of static size.
852 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
854 * hddtemp plugin: Error and warning messages have been improved.
855 * sensors plugin: Fix sensor collection for some chip types.
857 2008-03-29, Version 4.3.2
858 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
859 `Persist' threshold options.
860 * collectd: Fix handling of missing values in the global value cache.
861 * collectd: Improved error messages when parsing the configuration.

864 * wireless plugin: Fix reading noise value.
866 2008-03-05, Version 4.3.1
867 * exec plugin: Set supplementary group IDs.
869 + Use `memcpy' when constructing/parsing a package to avoid
870 alignment problems on weird architectures, such as Sparc.
871 + Translate doubles to/from the x86 byte representation to ensure
872 cross-platform compatibility.
873 * ping plugin: Correct the handling of the `TTL' setting.
874 * swap plugin: Reapply a patch for Solaris.
875 * tcpconns plugin: Portability improvements.
877 2008-02-18, Version 4.3.0
878 * collectd: Notifications have been added to the daemon. Notifications
879 are status messages that may be associated with a data instance.
880 * collectd: Threshold checking has been added to the daemon. This
881 means that you can configure threshold values for each data
882 instance. If this threshold is exceeded a notification will be
884 * collectd: The new `FQDNLookup' option tells the daemon to use the
885 full qualified domain name as the hostname, not just the host part
886 es returned by `gethostname(2)'.
887 * collectd: Support for more than one `TypesDB' file has been added.
888 This is useful when one such file is included in a package but one
889 wants to add custom type definitions.
890 * collectd: The `Include' config option has been expanded to handle
891 entire directories and shell wildcards.
892 * collectdmon: The new `collectdmon' binary detects when collectd
893 terminates and automatically restarts it again.
894 * csv plugin: The CSV plugin is now able to store counter values as a
895 rate, using the `StoreRates' configuration option.
896 * exec plugin: Handling of notifications has been added and the
897 ability to pass arguments to the executed programs has been added.
898 * hddtemp plugin: The new `TranslateDevicename' option lets you
899 disable the translation from device names to major-minor-numbers.
900 * logfile plugin: Handling of notifications has been added.
901 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
902 domain name lookups in this plugin.
903 * perl plugin: Many internal changes added support for handling multiple
904 threads making the plugin reasonably usable inside collectd. The API has
905 been extended to support notifications and export global variables to
906 Perl plugins; callbacks now have to be identified by name rather than a
907 pointer to a subroutine. The plugin is no longer experimental.
908 * uuid plugin: The new UUID plugin sets the hostname to an unique
909 identifier for this host. This is meant for setups where each client
910 may migrate to another physical host, possibly going through one or
911 more name changes in the process. Thanks to Richard Jones from
912 Red Hat's Emerging Technology group for this plugin.
913 * libvirt: The new libvirt plugin uses the `libvirt' library to query
914 CPU, disk and network statistics about guest systems on the same
915 physical server. Thanks to Richard Jones from Red Hat's Emerging
916 Technology group for this plugin.
918 2008-04-22, Version 4.2.7
919 * build system: Improved detection of several libraries, especially if
920 they are in non-standard paths.
921 * build system: Portability fixes: Automatically define "_REENTRANT"
922 if the libc expects it.
923 * collectd: Error and warning messages have been improved.
924 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
926 * apache plugin: Allocate new memory when reading a webpage instead of
927 using a buffer of static size.
928 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
930 * hddtemp plugin: Error and warning messages have been improved.
931 * sensors plugin: Fix sensor collection for some chip types.

939 2008-03-04, Version 4.2.5
940 * apache plugin: Improved initialization and error messages.
941 * exec plugin: Set supplementary group IDs.
943 + Create separate threads for reading from the socket and parsing
944 and dispatching incoming packets. Versions prior to this may have
945 problems in high-load situations, where the socket receive buffers
946 overflows, resulting in gaps in the data.
947 + Use `memcpy' when constructing/parsing a package to avoid
948 alignment problems on weird architectures, such as Sparc.
949 + Translate doubles to/from the x86 byte representation to ensure
950 cross-platform compatibility.
951 * ping plugin: Correct the handling of the `TTL' setting.
952 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
953 * swap plugin: Reapply a patch for Solaris.
954 * tcpconns plugin: Portability improvements.
956 2008-01-21, Version 4.2.4
957 * unixsock plugin: A bug in the unixsock plugin caused it not to set
958 the permission on the socket as documented in the manpage. Thanks to
959 Evgeny Chukreev for fixing this issue.
960 * collectd: The documentation has been improved.
962 2007-12-28, Version 4.2.3
963 * sensors plugin: Updated the plugin to build and work with version 3
964 of the libsensors library.
966 2007-12-15, Version 4.2.2
967 * nginx plugin: Incorrect comparison of strings lead to a segfault
968 when using the plugin. Thanks to Saulius Grigaliunas for fixing
970 * logfile plugin: The config option `Timestamp' was handled
971 incorrectly and basically always active. Thanks to Luke Heberling
974 2007-11-08, Version 4.2.1
975 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
977 * snmp plugin: Fix a memory leak.
979 2007-10-27, Version 4.2.0
980 * collectd: The new config option `Include' lets you include other
981 configfiles and thus split up your config into smaller parts. This
982 may be especially interesting for the snmp plugin to keep the data
983 definitions separate from the host definitions.
984 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
985 (number of connections, octets and packets for each service and
986 destination). Thanks to Sebastian Harl for this plugin.
987 * memcached plugin: The new `memcached' plugin connects to a memcached
988 daemon process and collects statistics of this distributed caching
989 system. Thanks to Antony Dovgal for contributing this plugin.
990 * nginx plugin: The new `nginx' plugin reads the status page of an
991 nginx daemon and saves the handled connections and requests.
992 * perl plugin: Many changes, including the added `EnableDebugger'
993 config option which lets you debug your Perl plugins more easily.
994 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
995 be more thread-safe otherwise by locking calls to the library.
996 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
997 correct the values returned by SNMP-agents. If a <data> block is
998 defined as `table' the instance is now optional. The sequence number
999 is used as the type-instance in this case. The new `InstancePrefix'
1000 option allows to add arbitrary prefixes to the type-instance.
1001 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1002 certain TCP connections and what state they're in. This can be used
1003 to see how many connections your FTP server has to handle or how
1004 many outgoing connections your mailserver has open.
1006 2008-01-11, Version 4.1.6
1007 * unixsock plugin: A bug in the unixsock plugin caused it not to set

1029 * collectd: A build issue under Solaris has been resolved by renaming
1031 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1032 be more thread-safe otherwise by locking calls to the library.
1034 2007-09-28, Version 4.1.2
1035 * apcups plugin: Fix reporting of the `load percent' data.
1036 * wireless plugin: Correct the handling of cards returning signal and

1057 whatever the client thinks is `now'..
1059 2007-09-01, Version 4.1.0
1060 * Build system: The build system has been changed to automatically
1061 disable all plugins, which are missing dependencies. The dependency
1062 checking has been removed from the plugins themselves to remove
1064 * Flexible interval: The interval of collected data is now sent along
1065 with the data itself over the network, so that the interval-settings
1066 of server and clients no longer needs to match.
1067 * netlink plugin: The new `netlink' plugin connects to the Linux
1068 kernel using a netlink socket and uses it to query information about
1069 interfaces, qdiscs and classes.
1070 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1071 to not block data collection.
1072 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1073 network devices, such as switches, routers, thermometers, rack
1074 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1076 * unixsock plugin: Added the `LISTVAL' command.
1077 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1078 of music played with xmms.

1097 * documentation: Some typos have been fixed and some information has
1099 * build system: Many fixes for detecting libraries in unusual places,
1100 such as on RedHat systems. The affected libraries are `libcurl',
1101 `libmysql', and `libupsclient'.
1102 * network plugin: Allow the `Port' option to be specified as a number
1103 (i. e. without quotes).
1104 * nut plugin: A fix allows linking the nut plugin against
1105 libupsclient, version >= 2.2.0.
1106 * processes plugin: Fix a potential segmentation fault.
1108 2007-07-30, Version 4.0.6
1109 * sensors plugin: Fix the ignorelist functionality: Only the `type
1110 instance' was used to match against the list, but the documentation
1111 told otherwise. This release fixes the code, so it complies with the
1113 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1114 configuration messages will end up in the logging facility.
1115 * conrtib/fedora: The contributed specfile for Fedora has been
1118 2007-07-05, Version 4.0.5
1119 * Portability: More fixes for OpenBSD have been included.

1145 2007-06-03, Version 4.0.0
1146 * collectd: The plugin-infrastructure has been changed to allow for
1147 more types of plugins, namely `write' and `log' plugins.
1148 * collectd: The read-function has been changed to read many plugins in
1149 parallel, using threads. Thus, plugins generally need to use
1150 thread-safe functions from now on.
1151 * collectd: The '-t' command line options allows to perform syntax tests
1152 of the configuration file and exit immediately.
1153 * csv plugin: The new `csv' plugin handles output to `comma separated
1155 * rrdtool plugin: The new `rrdtool' plugin handles output to
1156 RRD-files. Data can be cached to combine multiple updates into one
1157 write to increase IO-performance.
1158 * network plugin: The new `network' plugin handles IO via the network.
1159 It implements a different, much more extensible protocol which can
1160 combine many values in one packet, decreasing the number of UDP-
1161 packets being sent. It can read from and send to the network and
1162 with the appropriate configuration even forward packets to other
1164 * unixsock plugin: The new `unixsock' plugin provides an interface to
1165 communicate with the daemon while it is running. Right now the
1166 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1168 * perl plugin: The new `perl' plugin allows you to write extensions
1169 for collectd in the scripting-language Perl.
1170 * logfile plugin: The new `logfile' plugin writes logmessages to files
1171 or STDOUT or STDERR.
1172 * syslog plugin: The new `syslog' plugin sends logmessages to the
1173 system's syslog daemon.
1174 * entropy plugin: The new `entropy' plugin collects the amount of
1175 entropy currently being available to the system.
1176 * exec plugin: The new `exec' plugin forks child processes and reads
1177 back values provided by the forked processes.
1178 * iptables plugin: The new `iptables' plugin reads counters from
1179 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1181 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1182 to Peter Holik for contributing this plugin.
1183 * nut plugin: The new `nut' plugin connects the upsd of the `network
1184 ups tools' and reads information about the connected UPS.
1185 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1186 connections) field was added by Florent Monbillard.
1187 * collectd-nagios: The new `collectd-nagios' binary queries values
1188 from collectd, parses them and exits according to Nagios-standards.
1189 * manpages: The manpages have been improved a lot.
1191 2007-09-28, Version 3.11.7
1192 * wireless plugin: Correct the handling of cards returning signal and
1193 noise quality as percentage.
1195 2007-08-31, Version 3.11.6

1198 2007-05-29, Version 3.11.5
1199 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1200 * ntpd plugin: Fix a potential buffer overflow.
1201 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1202 were accounted as `zombies'.
1204 2007-04-10, Version 3.11.4
1205 * dns plugin: Change the order of includes to make the plugin compile
1208 2007-03-30, Version 3.11.3
1209 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1210 of the unused `COLLECT_KSTAT'.
1212 2007-02-11, Version 3.11.2
1213 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1214 NULL-pointer may have been passed to `printf' which causes a
1215 segfault with some libcs.
1217 2007-02-10, Version 3.11.1
1218 * df plugin: Some wrong defines have been fixed so the plugin works
1219 under Solaris again.
1220 * dns plugin: The usage of a struct has been fixed to work with
1222 * processes plugin: Some missing defines have been added so the plugin
1223 compiles cleanly under FreeBSD and presumably other UNIXes.
1225 2006-12-22, Version 3.11.0
1226 * collectd: The new command line option `-P' makes it easier for
1227 distributors to change the location of PID-files.
1228 * collectd: The daemon shuts down faster now which makes it easier to
1229 write init.d-scripts for it.
1230 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1231 caused problems every now and then.
1232 * df plugin: New config options allow to ignore certain mountpoints,
1233 filesystem types or devices.
1234 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1235 and interprets it. It collects traffic as well as qtype, opcode and
1237 * email plugin: Sebastian Harl has contributed this plugin which
1238 counts received mails in categories (e. g. ham, spam, virus), spam
1239 score (as given by SpamAssassin) and check types.
1240 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1241 uses `mbmon' to gather information from sensors on the motherboard.
1242 * processes plugin: Collect detailed statistics for configured
1243 processes, that's process and thread count, CPU usage, resident
1244 segment size and pagefaults.
1245 * multimeter plugin: Peter Holik contributed a new plugin which
1246 queries multimeters.
1247 * sensors plugin: Lubos Stanek has put much effort into improving this
1248 plugin, including `extended naming', collection of voltage values
1249 and the possibility to ignore certain values.
1251 2006-12-21, Version 3.10.4
1252 * Max Kellermann has identified a bug in the server routine: When
1253 opening a socket fails the daemon will (re)try opening the socket in
1254 an endless loop, ultimately leading to a `EMFILE' error.
1256 2006-11-04, Version 3.10.3
1257 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1258 ntpd's reply was sent in more than one packet, the buffer size was
1259 calculated incorrectly, resulting in the reading of uninitialized or
1262 2006-11-01, Version 3.10.2
1263 * The sample config file has been improved.
1264 * Errors in the manpages have been corrected.
1265 * The ping-plugin now adds hosts during initialization, not during
1266 startup. This speeds up startup when no network connectivity is
1267 available. Also, the hosts are being added later when the network is
1269 * Improved BSD-support for the df-plugin.
1270 * Fixed syntax errors in the swap-plugin for Mac OS X.
1271 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1273 * Don't disable the mysql-plugin if connecting to the database fails
1274 during initialization. Instead, try again in increasing intervals.
1276 2006-07-19, Version 3.10.1
1277 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1278 the apcups cannot be reached, unconnected sockets will pile up and
1279 eventually lead to `Too many open files' errors.
1281 2006-07-09, Version 3.10.0
1282 * The `disk' plugin has been ported to Darwin.
1283 * The `battery' plugin should work on many Apple computers now.
1284 * The `traffic' plugin can now ignore certain interfaces. Also,
1285 statistics for sent/received packets and errors have been added.

1287 to Anthony Gialluca for contributing this plugin and providing me
1288 with a test environment :)
1289 * A plugin for monitoring an NTP instance and the local clock drift
1292 2006-06-25, Version 3.9.4
1293 * The Solaris code in the `swap' plugin has been changed to reflect
1294 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1296 * The debugging system has been fixed to work with the Sun libc.
1297 * When built without librrd the variable `operating_mode' could be
1298 uninitialized. Thanks to David Elliot for reporting the bug.
1300 2006-06-01, Version 3.9.3
1301 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1302 operating systems also profit from the changes, but I wasn't able to
1304 * Changed the build system to find the netinet-includes under FreeBSD
1305 and therefore successfully build the `liboping' library there.
1307 2006-05-09, Version 3.9.2
1308 * Applied a patch to the `liboping' library. Due to a bug in the
1309 sequence checking the `ping' plugin stopped working after
1310 approximately 7.6 days.
1312 2006-05-09, Version 3.8.5
1313 * Applied a patch to the `liboping' library. Due to a bug in the
1314 sequence checking the `ping' plugin stopped working after
1315 approximately 7.6 days.
1317 2006-04-21, Version 3.9.1
1318 * Build issues with Solaris and possible other architectures have been
1320 * Problems when building the `apache'-plugin without `libcurl' have
1322 * A bug in the `ping' plugin has been fixed. Sorry folks.
1324 2006-04-02, Version 3.9.0
1325 * A plugin to monitor the Apache webserver has been added.
1326 <http://httpd.apache.org/>
1327 * A plugin to collect statistics about virtual servers using VServer.
1328 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1330 * A plugin for wireless LAN cards has been added. It monitors signal
1331 strength, link quality and noise ratio..
1332 * A plugin for Apple hardware sensors has been added.
1333 * An option to compile collectd with different `step' and `heartbeat'
1334 settings has been added. The size of RRAs is no longer static but
1335 calculated based on the settings for `step' and `width'.
1336 * The `ping' plugin can now be configured to use a certain TTL.
1337 * A plugin to monitor the hardware sensors of Apple computers has been
1339 * The plugins `cpu', `memory', `processes' and `traffic' have been
1340 ported to Mach/Darwin (Mac OS X).
1341 * The `log mode' has been contributed by Christophe Kalt. It writes
1342 the data into text files rather than RRD files.
1344 2006-04-09, Version 3.8.4
1345 * Applied patch by Vincent Stehlé which improves the disk-name
1346 resolution in the `hddtemp' plugin for Linux systems.
1348 2006-04-02, Version 3.8.3
1349 * Applied a patch by James Byers: The MySQL plugin was not working
1350 with MySQL 5.0.2 or later.
1352 2006-03-14, Version 3.8.2
1353 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1354 the GNU libc, because it points to `/etc/fstab' rather than
1357 2006-03-13, Version 3.8.1
1358 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1359 * Fixes in the debian `postinst' and `init.d' scripts.
1361 2006-03-09, Version 3.8.0
1362 * The `ping' plugin no longer uses `libping' but a self written
1363 library named `liboping'. With this library it's possible to ping
1364 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1366 2006-02-18, Version 3.7.2
1367 * A simple bug in the `battery' plugin has been fixed. It should now
1368 work with ACPI based batteries as well. Thanks to Sebastian for
1370 * Fixing a bug that prevented collectd to be built without librrd.
1371 Thanks to Werner Heuser for reporting it.
1373 2006-02-04, Version 3.7.1
1374 * The new network code has been improved to build with older versions
1376 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1377 to Tommie Gannert for this patch.
1379 2006-01-30, Version 3.7.0
1380 * The `battery' plugin has been added. It collects information about
1382 * The MySQL plugin has been improved: It now writes two more RRD
1383 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1384 * The `cpufreq' plugin now reads another file since the file it did
1385 read so far causes much overhead in the kernel. Also, you need root
1386 to read the old file, but not to read the new one.
1387 * The `hddtemp' plugin can now be configured to connect to another
1388 address and/or port than localhost.
1389 * The `df' plugin now prefers `statvfs' over `statfs'.
1390 * The network code has been rewritten. collectd now supports unicast
1391 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1392 be set in the configfile.
1394 2006-01-24, Version 3.6.2
1395 * Due to a bug in the configfile handling collectd wouldn't start in
1396 client mode. This released fixes this.
1398 2006-01-20, Version 3.6.1
1399 * Due to a bug in `configure.in' all modules and the binary were
1400 linked against `libmysqlclient'. This issue is solved by this
1403 2006-01-17, Version 3.6.0
1404 * A config file has been added. This allows for loading only specific
1406 * A `df' plugin has been added.
1407 * A `mysql' plugin has been added.
1408 * The `ping' plugin doesn't entirely give up hope when a socket error
1409 occurred, but will back of and increase the intervals between tries.
1411 2006-01-21, Version 3.5.2
1412 * Fixed yet another bug in the signal handling.. Stupid typo..
1413 * Improved the ping plugin to not give up on socket errors (backport
1416 2005-12-18, Version 3.5.1
1417 * The PID-file is now deleted correctly when shutting down the daemon.
1418 * SIGINT and SIGTERM are now handled correctly.
1420 2005-12-16, Version 3.5.0 (Revision 326)
1421 * A bug in the `load' module under Solaris has been fixed.
1422 * The `users' module has been contributed by Sebastian Harl. It counts
1423 currently logged in users.
1424 * The CPU module now works under FreeBSD without the use of
1425 `libstatgrab', however SMP support is missing.
1426 * The default directories for the RRD files and the PID file now
1427 depend on the compile time setting of `localstatedir'.
1429 2005-11-15, Version 3.4.0 (Revision 236)
1430 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1431 from gentoo's bugzilla for writing the patch.
1432 * The build dependency for librrd has been removed. Binaries built
1433 without librrd are client-only and will multicast their value as
1434 with the `-c' argument.
1435 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1436 * The newly introduced `-f' switch prevents daemon initialization
1437 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1438 Barcellos for this patch.
1440 2005-11-04, Version 3.3.0 (Revision 216)
1441 * New modules have been added:
1442 - `serial', for monitoring traffic on the serial interfaces
1443 - `nfs', for graphing NFS procedure calls
1444 - `tape', traffic from/to tape devices
1445 * The memory.rrd now accepts more than 4Gig of memory.
1447 2005-10-26, Version 3.2.0 (Revision 200)
1448 * Support for graphing the processes has been added (thanks to Lyonel

1451 between polls up to one day.
1452 * The init.d files have been improved.
1453 * Problems with the spec file have been fixed.
1455 2005-10-16, Version 3.1.0 (Revision 194)
1456 * Added the `setsid' syscall to the startup code.
1457 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1459 2005-09-30, Version 3.0.0 (Revision 184)
1460 * The ability to send/receive data to/from the network (think
1461 multicast) has been added.
1462 * Modules have been split up into shared libraries can be loaded at
1463 runtime. The biggest advantage is that the core program doesn't need
1464 to be linked against an external library.
1465 * A patch by George Kargiotakis has been applied: It fixes the sensors
1466 behaviour then more than one sensor is being queried.
1468 2005-09-16, Version 2.1.0 (Revision 172)
1469 * A module for swap statistics has been added.
1471 2005-09-09, Version 2.0.0 (Revision 135)
1472 * Filenames can no longer be configured at program startup. The only
1473 options as of this version are the directory and ping hosts.
1474 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1475 Soft-IRQ statistics are added to `System'.
1476 * Diskstats now collect read and write bytes, not sectors.
1477 * Ping statistics can now be collected for more than one host. There
1478 is no default any more: If no host is given no host will be pinged.
1479 * A self-written patch for libping has been applied so it builds
1482 2005-09-01, Version 1.8.1 (Revision 123)
1483 * Much improved configure-script: libraries and features may now be
1485 * More detailed warnings/error messages when RRD update fails.
1487 2005-08-29, Version 1.8.0:
1488 * Support for collecting disk statistics under Solaris.
1490 2005-08-25, Version 1.7.0:
1491 * Support for libstatgrab[1] for load, memory usage and network
1492 traffic. CPU- and disk-usage are not (yet) supported, since
1493 libstatgrab returns insufficient information. I will contact the
1495 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1496 aren't necessarily counted linear which is now handled correctly.

1499 2005-08-21, Version 1.6.0:
1500 * Basic support for Solaris: System load and cpu-usage can be
1501 collected under Solaris, too. Other stats will follow later.
1502 * Many fixes in the autoconf-script
1503 * Collection/Museum scripts have been added under contrib/museum
1504 * collectd may now be started in unprivileged mode, though ping
1505 statistics will not work.
1507 2005-07-17, Version 1.5.1:
1508 * Diskstats-RRDs now use major/minor for naming. Some systems have
1509 weird strings as disk-names..
1511 2005-07-17, Version 1.5:
1512 * A new module, diskstats, has been added. It collects information
1513 about the disks and partitions.
1515 2005-07-11, Version 1.4.2:
1516 * The meminfo module has been changed to work with more platforms
1517 and/or kernel versions.
1519 2005-07-10, Version 1.4.1: Correct traffic stats
1520 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1521 forgot to correct when I changed that module.
1523 2005-07-09, Version 1.4: More traffic stats
1524 * Traffic is now collected for all interfaces that can be found
1525 * Temperature-statistics are read from lm-sensors if available
1527 2005-07-08, Version 1.3: CPU stats
1528 * Collecting CPU statistics now
1530 2005-07-12, Version 1.2: Using syslog
1531 * collectd is now using the syslog facility to report errors, warnings
1533 * The default directory is now /var/db/collectd
1535 2005-07-10, Version 1.1: Minor changes
1536 * Nothing really useful to say ;)
1538 2005-07-09, Version 1.0: Initial Version
