493 been added. Thanks to Fabian Linzberger for the patch.
494 * libcollectdclient: A library which abstracts communication with the
495 unixsock plugin for clients has been added.
496 * regex match: Match values by their identifies using regular
498 * timediff match: Match for values with an invalid timestamp.
499 * value match: Select values by their data sources' values.
500 * notification target: Create and dispatch a notification.
501 * replace target: Replace parts of an identifier using regular
503 * set target: Set (overwrite) entire parts of an identifier.
504 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
505 statistics, allowing very detailed name server statistics. Thanks to
506 Bruno Prémont for this plugin.
507 * cpu plugin: Report `interrupt' separately when using
508 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
509 example for native OpenBSD support, has been added. Thanks to Simon
510 Kuhnle for the patch.
511 * csv plugin: Make it possible to write values to STDOUT instead of
512 files. This is meant for testing purposes mostly. The output written
513 to STDOUT is compatible with the exec plugin. Thanks to Doug
514 MacEachern for the patch.
515 * curl plugin: This new plugin can be used to read web pages and parse
516 them using the same mechanism that's used in the tail plugin.
517 * dbi plugin: This new plugin allows you to connect to a variety of
518 relational databases and use SQL to gather custom statistics from
519 it. It is similar to the already existing PostgreSQL plugin but uses
520 libdbi to communicate with the database(s).
521 * interface plugin: Use the ignorelist framework when selecting /
522 ignoring interfaces. This allows one to use regular expressions to
523 select interfaces, too.
524 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
525 Thanks to Bruno Prémont for this patch.
526 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
528 * mysql plugin: Allow connecting to a database via the UNIX domain
529 socket, too. Thanks to Mirko Buffoni for the patch.
530 * network plugin: Further performance improvements for the receive
531 code. This hopefully will help very large setups.
532 * openvpn plugin: This new plugin collects statistics provided by the
533 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
534 * oracle plugin: This new plugin allows you to connect to an Oracle
535 database and use SQL to gather custom statistics from it. It is
536 similar to the already existing PostgreSQL plugin.
537 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
539 * perl plugin: Export the newly added plugin_write() to Perl plugins.
540 * perl plugin: Added support for `notification meta data'.
541 * perl plugin: Added support for the `filter chain' infrastructure by
542 allowing plugins to register `matches' and `targets'.
543 * postgresql plugin: The preferred configuration syntax has been
544 updated to be in line with the syntax used by the new dbi and oracle
545 plugins. The compatibility code for the old syntax is present.
546 Support for the new `Result' blocks and the interval parameter has
548 * processes plugin: Stacksize and virtual memory usage statistics have
549 been added. Portability fixes.
550 * rrdcached plugin: This new plugin uses the (still in development)
551 RRD accelerator daemon, rrdcached. This daemon works very similar to
552 the original rrdtool plugin of collectd, but adds some more nice
554 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
557 2009-05-09, Version 4.5.4
558 * Build system, various plugins: Many build fixes for FreeBSD,
559 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
560 for many fixes and providing a build system for many platforms,
561 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
562 providing an OpenBSD system.
563 * collectd: Fix a potential race condition when creating directories.
564 * battery plugin: Don't complain about a missing directory every
566 * dns plugin: Slight portability fixes.
567 * exec plugin: Allow executed programs to close STDERR. Thanks to
568 Thorsten von Eicken for reporting this problem.
569 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
570 Tomasz Pala for the patch.
571 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
573 * rrdtool plugin: Fix a possible race condition: If the network plugin
574 is initialized and dispatches a value before the rrdtool plugin is
575 initialized, the daemon may crash.
576 * memory plugin: Fix a potential problem under Solaris.
578 2009-02-22, Version 4.5.3
579 * build system: The check for libupsclient even when `pkg-config' is
581 * collectd: Fix error handling in the global cache.
582 * Collectd::Unixsock: Error handling has been improved.
583 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
585 * ipmi plugin: Fix an off-by-one error which could cause segmentation
586 faults. Thanks to Peter Holik for his patch.
587 * tcpconns plugin: An endianness problem has been fixed in the *BSD
588 code. Thanks to "thated" for reporting this.
590 2009-01-02, Version 4.5.2
591 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
592 file may be in both locations, especially when the database was
593 installed in a non-standard path. Thanks to Dusty Doris for
595 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
596 Solaris, in the configure script automatically.
597 * build system, tcpconns plugin: Check for `kvm_nlist' and
598 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
599 library with similar functions to the BSD variant, but doesn't
600 provide these necessary functions.
601 * collectd.conf(5): Various fixes and clarifications.
602 * collectd: Remove a GNUism (unnamed unions), thus improving
604 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
605 This solves portability problems, especially for Solaris.
606 * dns plugin: Fix a portability problem with NetBSD.
607 * filecount plugin: Fix an off-by-one error. This error may cause a
609 * network plugin: Fix the handling of `type' in the network protocol.
610 Due to a programming mistake, only 4 or 8 bytes would be copied to a
611 much larger buffer. This caused the `type' to be transferred much
612 more often than necessary. In some cases, e. g. the `cpu' and
613 `cpufreq' plugins being used at the same time, data may be corrupted
614 in those files. Thanks to Bruno Prémont for debugging and reporting
616 * processes plugin: Fix a possible segmentation fault when specifying
617 invalid configuration options.
618 * unixsock plugin: Make sure the initialization function is run only
619 once. This resolves a file descriptor leak under systems which run
620 the initialization more than once, such as Solaris.
622 2008-10-16, Version 4.5.1
623 * build system: Change `--enable-<plugin>' to abort with an error if
624 dependencies are not met. Thanks to Bruno Prémont for the patch.
625 Also, the poisoning of various string functions has been restricted
627 * collectd: Fix a memory leak in the global value cache. With every
628 *missing* value a couple of bytes would be leaked. Another memory
629 leak in the configuration handling code has been fixed. Thanks to
630 Niraj Tolia for reporting these issues.
631 * collectd: Fix an off-by-one error in the ignorelist functionality.
632 When using regular expressions, the last character would be missing,
633 possibly matching differently from what one would expect.
634 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
636 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
637 Linzberger for reporting the bug.
638 * iptables plugin: Fix an off-by-one error. If a string was just one
639 character too long, it was truncated instead of reporting an error.
640 * network plugin: Fix a memory leak in the configuration handling
641 code. Thanks to Niraj Tolia for reporting this issue.
642 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
643 * postgresql plugin: Don't reopen connection during reinitialization.
644 This fixes a bug under Solaris and potentially other platforms.
645 Missing calls to `PQclear' have been added, too. This fixes memory
646 leaks. Thanks to ``Admin'' for reporting these bugs.
647 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
649 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
650 problems with some `libc's. Thanks to Matthias Lay for reporting the
653 2008-09-04, Version 4.5.0
654 * collectd: Added the ability to flush certain identifiers.
655 * collectd: The concept of `notification meta data' has been
657 * filecount plugin: The new filecount plugin counts the number of
658 files in a directory and its subdirectories.
659 * ipmi plugin: Sensor names have been changed to ensure unique names.
660 Notifications upon added and removed sensors can now be generated.
661 * notify_desktop plugin: This new plugin sends notifications to the
662 X desktop using the structure defined in the `Desktop Notification
664 * notify_email plugin: This new plugin sends out notifications via
665 email, using the `esmtp' library.
666 * onewire plugin: The new experimental(!) onewire plugin reads values,
667 such as temperatures, from sensors connected to the computer via the
669 * perl plugin: Improved synchronized access to internal data structures
670 and fixed a possible dead-lock.
671 * perl plugin: Added the ability to flush certain identifiers and marked
672 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
674 * perl plugin: Added the ability to configure Perl plugins.
675 * postgresql plugin: The new postgresql plugin collects statistics
676 about or from a PostgreSQL database.
677 * processes plugin: The `ProcessMatch' option has been added.
678 * rrdtool plugin: Implement throttling of the `update queue' to lessen
680 * tcpconns plugin: This plugin has been ported to OpenBSD.
681 * thermal plugin: The new thermal plugin collects system temperatures
682 using Linux ACPI thermal zone data.
684 2009-01-02, Version 4.4.5
685 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
686 file may be in both locations, especially when the database was
687 installed in a non-standard path. Thanks to Dusty Doris for
689 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
690 Solaris, in the configure script automatically.
691 * collectd.conf(5): Various fixes and clarifications.
692 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
693 portability problems, especially for Solaris.
694 * dns plugin: Fix a portability problem with NetBSD.
695 * network plugin: Fix the handling of `type' in the network protocol.
696 Due to a programming mistake, only 4 or 8 bytes would be copied to a
697 much larger buffer. This caused the `type' to be transferred much
698 more often than necessary. In some cases, e. g. the `cpu' and
699 `cpufreq' plugins being used at the same time, data may be corrupted
700 in those files. Thanks to Bruno Prémont for debugging and reporting
702 * unixsock plugin: Make sure the initialization function is run only
703 once. This resolves a file descriptor leak under systems which run
704 the initialization more than once, such as Solaris.
706 2008-10-16, Version 4.4.4
707 * build system: Change `--enable-<plugin>' to abort with an error if
708 dependencies are not met. Thanks to Bruno Prémont for the patch.
709 Also, the poisoning of various string functions has been restricted
711 * collectd: Fix a memory leak in the global value cache. With every
712 *missing* value a couple of bytes would be leaked. Another memory
713 leak in the configuration handling code has been fixed. Thanks to
714 Niraj Tolia for reporting these issues.
715 * collectd: Fix an off-by-one error in the ignorelist functionality.
716 When using regular expressions, the last character would be missing,
717 possibly matching differently from what one would expect.
718 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
720 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
721 Linzberger for reporting the bug.
722 * network plugin: Fix a memory leak in the configuration handling
723 code. Thanks to Niraj Tolia for reporting this issue.
724 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
725 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
726 problems with some `libc's. Thanks to Matthias Lay for reporting the
729 2008-09-01, Version 4.4.3
730 * collectd: Fix a memory leak in the threshold checking code.
731 * memcached plugin: Fix a too short timeout and a related file
733 * memory plugin: A typo in the libstatgrab code has been fixed.
734 * snmp plugin: Fix a possible memory leak.
736 2008-07-15, Version 4.4.2
737 * build system: Use pkg-config to detect the upsclient library.
738 * collectd: Try even harder to determine the endianess of the
739 architecture collectd is being built on.
740 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
742 * dns plugin: Fix compilation errors with BIND versions 19991001
744 * network plugin: Bugfix in the init routine: The init function
745 cleared a buffer regardless of its contents. This could lead to lost
746 values under Solaris.
747 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
748 * vserver plugin: Remove usage of the thread-unsafe `readdir'
750 * wireless plugin: Work around incorrect noise and power values
751 returned by some broken drivers.
753 2008-06-03, Version 4.4.1
754 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
755 to kyrone for reporting this.
756 * collectd: Fixed min/max output in notifications generated by
758 * collectd-nagios: Fix the protocol used to communicate with the
760 * perl plugin: Fail noisily, but don't shutdown the daemon, if
761 initialization has errors. An issue with Perl 5.10 has been fixed.
762 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
763 René Rebe and Siegmund Gorr for reporting this.
765 2008-05-06, Version 4.4.0
766 * collectd: Internal code cleanups.
767 * collectd: Added support for a `Flush' command in the unixsock and
768 exec plugins. This command can be used to force a plugin (or all) to
769 flush its values to disk.
770 * collectd: Thresholds can now be configured to apply to one data
771 source only, making it possible to configure different thresholds
772 for each data source.
773 * apache, nginx plugins: Added the possibility to disable host and/or
775 * ascent plugin: The new ascent plugin reads and parses the statistics
776 page of an Ascent server.
777 * cpu plugin: Support for the statgrab library has been added.
778 * disk plugin: The possibility to ignore certain disks or collect only
779 specific disks has been added.
780 * disk plugin: Support for the statgrab library has been added.
781 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
782 sensor values via IPMI, the intelligent platform management
784 * iptables plugin: The iptc library that is used by the iptables
785 plugin has been added to the distribution, because it is not
786 provided by all distributions and removed from at least one.
787 * powerdns plugin: The new powerdns plugin reads statistics from an
788 authoritative or a recursing PowerDNS name server.
789 * rrdtool plugin: The size of the files generated with the default
790 configuration has been decreased.
791 * tail plugin: The new tail plugin can be used to gather statistics by
792 continuously reading from log files.
793 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
794 TeamSpeak2 server and collects statistics about the number of users
795 and number of channels.
796 * users plugin: Support for the statgrab library has been added.
797 * vmem plugin: The new vmem plugin collects very detailed statistics
798 about the virtual memory subsystem of Linux.
800 2008-08-30, Version 4.3.4
801 * Build system: Improved detection of and linking with the statgrab
803 * collectd: Portability fixes, especially to determine endianess more
805 * Various plugins: Fix format strings.
806 * disk plugin: A fix for giving disks under Linux 2.4 the right names
807 again has been applied.
808 * memcached plugin: Fix a too short timeout and a related file
810 * memory plugin: A typo in the libstatgrab code has been fixed.
811 * network plugin: A fix in the initialization function solves problems
813 * nginx plugin: A thread-unsafe function has been replaced.
814 * vserver plugin: A thread-unsafe function has been replaced.
815 * wireless plugin: A work-around for broken wireless drivers has been
818 2008-04-22, Version 4.3.3
819 * build system: Improved detection of several libraries, especially if
820 they are in non-standard paths.
821 * build system: Portability fixes: Automatically define "_REENTRANT"
822 if the libc expects it.
823 * collectd: Error and warning messages have been improved.
824 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
826 * apache plugin: Allocate new memory when reading a webpage instead of
827 using a buffer of static size.
828 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
830 * hddtemp plugin: Error and warning messages have been improved.
831 * sensors plugin: Fix sensor collection for some chip types.
833 2008-03-29, Version 4.3.2
834 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
835 `Persist' threshold options.
836 * collectd: Fix handling of missing values in the global value cache.
837 * collectd: Improved error messages when parsing the configuration.
838 * sensors plugin: Fix temperature collection with libsensors4.
839 * unixsock plugin: Fix mixed input and output operation on streams.
840 * wireless plugin: Fix reading noise value.
842 2008-03-05, Version 4.3.1
843 * exec plugin: Set supplementary group IDs.
845 + Use `memcpy' when constructing/parsing a package to avoid
846 alignment problems on weird architectures, such as Sparc.
847 + Translate doubles to/from the x86 byte representation to ensure
848 cross-platform compatibility.
849 * ping plugin: Correct the handling of the `TTL' setting.
850 * swap plugin: Reapply a patch for Solaris.
851 * tcpconns plugin: Portability improvements.
853 2008-02-18, Version 4.3.0
854 * collectd: Notifications have been added to the daemon. Notifications
855 are status messages that may be associated with a data instance.
856 * collectd: Threshold checking has been added to the daemon. This
857 means that you can configure threshold values for each data
858 instance. If this threshold is exceeded a notification will be
860 * collectd: The new `FQDNLookup' option tells the daemon to use the
861 full qualified domain name as the hostname, not just the host part
862 es returned by `gethostname(2)'.
863 * collectd: Support for more than one `TypesDB' file has been added.
864 This is useful when one such file is included in a package but one
865 wants to add custom type definitions.
866 * collectd: The `Include' config option has been expanded to handle
867 entire directories and shell wildcards.
868 * collectdmon: The new `collectdmon' binary detects when collectd
869 terminates and automatically restarts it again.
870 * csv plugin: The CSV plugin is now able to store counter values as a
871 rate, using the `StoreRates' configuration option.
872 * exec plugin: Handling of notifications has been added and the
873 ability to pass arguments to the executed programs has been added.
874 * hddtemp plugin: The new `TranslateDevicename' option lets you
875 disable the translation from device names to major-minor-numbers.
876 * logfile plugin: Handling of notifications has been added.
877 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
878 domain name lookups in this plugin.
879 * perl plugin: Many internal changes added support for handling multiple
880 threads making the plugin reasonably usable inside collectd. The API has
881 been extended to support notifications and export global variables to
882 Perl plugins; callbacks now have to be identified by name rather than a
883 pointer to a subroutine. The plugin is no longer experimental.
884 * uuid plugin: The new UUID plugin sets the hostname to an unique
885 identifier for this host. This is meant for setups where each client
886 may migrate to another physical host, possibly going through one or
887 more name changes in the process. Thanks to Richard Jones from
888 Red Hat's Emerging Technology group for this plugin.
889 * libvirt: The new libvirt plugin uses the `libvirt' library to query
890 CPU, disk and network statistics about guest systems on the same
891 physical server. Thanks to Richard Jones from Red Hat's Emerging
892 Technology group for this plugin.
894 2008-04-22, Version 4.2.7
895 * build system: Improved detection of several libraries, especially if
896 they are in non-standard paths.
897 * build system: Portability fixes: Automatically define "_REENTRANT"
898 if the libc expects it.
899 * collectd: Error and warning messages have been improved.
900 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
902 * apache plugin: Allocate new memory when reading a webpage instead of
903 using a buffer of static size.
904 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
906 * hddtemp plugin: Error and warning messages have been improved.
907 * sensors plugin: Fix sensor collection for some chip types.
909 2008-03-29, Version 4.2.6
910 * collectd: Improved error messages when parsing the configuration.
911 * sensors plugin: Fix temperature collection with libsensors4.
912 * unixsock plugin: Fix mixed input and output operation on streams.
913 * wireless plugin: Fix reading noise value.
915 2008-03-04, Version 4.2.5
916 * apache plugin: Improved initialization and error messages.
917 * exec plugin: Set supplementary group IDs.
919 + Create separate threads for reading from the socket and parsing
920 and dispatching incoming packets. Versions prior to this may have
921 problems in high-load situations, where the socket receive buffers
922 overflows, resulting in gaps in the data.
923 + Use `memcpy' when constructing/parsing a package to avoid
924 alignment problems on weird architectures, such as Sparc.
925 + Translate doubles to/from the x86 byte representation to ensure
926 cross-platform compatibility.
927 * ping plugin: Correct the handling of the `TTL' setting.
928 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
929 * swap plugin: Reapply a patch for Solaris.
930 * tcpconns plugin: Portability improvements.
932 2008-01-21, Version 4.2.4
933 * unixsock plugin: A bug in the unixsock plugin caused it not to set
934 the permission on the socket as documented in the manpage. Thanks to
935 Evgeny Chukreev for fixing this issue.
936 * collectd: The documentation has been improved.
938 2007-12-28, Version 4.2.3
939 * sensors plugin: Updated the plugin to build and work with version 3
940 of the libsensors library.
942 2007-12-15, Version 4.2.2
943 * nginx plugin: Incorrect comparison of strings lead to a segfault
944 when using the plugin. Thanks to Saulius Grigaliunas for fixing
946 * logfile plugin: The config option `Timestamp' was handled
947 incorrectly and basically always active. Thanks to Luke Heberling
950 2007-11-08, Version 4.2.1
951 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
953 * snmp plugin: Fix a memory leak.
955 2007-10-27, Version 4.2.0
956 * collectd: The new config option `Include' lets you include other
957 configfiles and thus split up your config into smaller parts. This
958 may be especially interesting for the snmp plugin to keep the data
959 definitions separate from the host definitions.
960 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
961 (number of connections, octets and packets for each service and
962 destination). Thanks to Sebastian Harl for this plugin.
963 * memcached plugin: The new `memcached' plugin connects to a memcached
964 daemon process and collects statistics of this distributed caching
965 system. Thanks to Antony Dovgal for contributing this plugin.
966 * nginx plugin: The new `nginx' plugin reads the status page of an
967 nginx daemon and saves the handled connections and requests.
968 * perl plugin: Many changes, including the added `EnableDebugger'
969 config option which lets you debug your Perl plugins more easily.
970 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
971 be more thread-safe otherwise by locking calls to the library.
972 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
973 correct the values returned by SNMP-agents. If a <data> block is
974 defined as `table' the instance is now optional. The sequence number
975 is used as the type-instance in this case. The new `InstancePrefix'
976 option allows to add arbitrary prefixes to the type-instance.
977 * tcpconns plugin: The new `tcpconns' plugin collects the number of
978 certain TCP connections and what state they're in. This can be used
979 to see how many connections your FTP server has to handle or how
980 many outgoing connections your mailserver has open.
982 2008-01-11, Version 4.1.6
983 * unixsock plugin: A bug in the unixsock plugin caused it not to set
984 the permission on the socket as documented in the manpage. Thanks to
985 Evgeny Chukreev for fixing this issue.
986 * collectd: The documentation has been improved.
988 2007-12-27, Version 4.1.5
989 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

1004 2007-10-24, Version 4.1.3
1005 * collectd: A build issue under Solaris has been resolved by renaming
1007 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1008 be more thread-safe otherwise by locking calls to the library.
1010 2007-09-28, Version 4.1.2
1011 * apcups plugin: Fix reporting of the `load percent' data.
1012 * wireless plugin: Correct the handling of cards returning signal and

1035 2007-09-01, Version 4.1.0
1036 * Build system: The build system has been changed to automatically
1037 disable all plugins, which are missing dependencies. The dependency
1038 checking has been removed from the plugins themselves to remove
1040 * Flexible interval: The interval of collected data is now sent along
1041 with the data itself over the network, so that the interval-settings
1042 of server and clients no longer needs to match.
1043 * netlink plugin: The new `netlink' plugin connects to the Linux
1044 kernel using a netlink socket and uses it to query information about

1068 has an `apcups_' prefix which doesn't work anymore.
1069 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1070 whatever the client thinks is `now'..
1072 2007-08-26, Version 4.0.7
1073 * documentation: Some typos have been fixed and some information has
1075 * build system: Many fixes for detecting libraries in unusual places,
1076 such as on RedHat systems. The affected libraries are `libcurl',
1077 `libmysql', and `libupsclient'.
1078 * network plugin: Allow the `Port' option to be specified as a number
1079 (i. e. without quotes).
1080 * nut plugin: A fix allows linking the nut plugin against
1081 libupsclient, version >= 2.2.0.
1082 * processes plugin: Fix a potential segmentation fault.
1084 2007-07-30, Version 4.0.6
1085 * sensors plugin: Fix the ignorelist functionality: Only the `type
1086 instance' was used to match against the list, but the documentation
1087 told otherwise. This release fixes the code, so it complies with the
1089 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1090 configuration messages will end up in the logging facility.
1091 * conrtib/fedora: The contributed specfile for Fedora has been
1094 2007-07-05, Version 4.0.5
1095 * Portability: More fixes for OpenBSD have been included.

1121 2007-06-03, Version 4.0.0
1122 * collectd: The plugin-infrastructure has been changed to allow for
1123 more types of plugins, namely `write' and `log' plugins.
1124 * collectd: The read-function has been changed to read many plugins in
1125 parallel, using threads. Thus, plugins generally need to use
1126 thread-safe functions from now on.
1127 * collectd: The '-t' command line options allows to perform syntax tests
1128 of the configuration file and exit immediately.
1129 * csv plugin: The new `csv' plugin handles output to `comma separated
1131 * rrdtool plugin: The new `rrdtool' plugin handles output to
1132 RRD-files. Data can be cached to combine multiple updates into one
1133 write to increase IO-performance.
1134 * network plugin: The new `network' plugin handles IO via the network.
1135 It implements a different, much more extensible protocol which can
1136 combine many values in one packet, decreasing the number of UDP-
1137 packets being sent. It can read from and send to the network and
1138 with the appropriate configuration even forward packets to other
1140 * unixsock plugin: The new `unixsock' plugin provides an interface to
1141 communicate with the daemon while it is running. Right now the
1142 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1144 * perl plugin: The new `perl' plugin allows you to write extensions
1145 for collectd in the scripting-language Perl.
1146 * logfile plugin: The new `logfile' plugin writes logmessages to files
1147 or STDOUT or STDERR.
1148 * syslog plugin: The new `syslog' plugin sends logmessages to the
1149 system's syslog daemon.
1150 * entropy plugin: The new `entropy' plugin collects the amount of
1151 entropy currently being available to the system.

1153 back values provided by the forked processes.
1154 * iptables plugin: The new `iptables' plugin reads counters from
1155 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1157 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1158 to Peter Holik for contributing this plugin.
1159 * nut plugin: The new `nut' plugin connects the upsd of the `network
1160 ups tools' and reads information about the connected UPS.
1161 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1162 connections) field was added by Florent Monbillard.
1163 * collectd-nagios: The new `collectd-nagios' binary queries values
1164 from collectd, parses them and exits according to Nagios-standards.
1165 * manpages: The manpages have been improved a lot.
1167 2007-09-28, Version 3.11.7
1168 * wireless plugin: Correct the handling of cards returning signal and
1169 noise quality as percentage.
1171 2007-08-31, Version 3.11.6

1174 2007-05-29, Version 3.11.5
1175 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1176 * ntpd plugin: Fix a potential buffer overflow.
1177 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1178 were accounted as `zombies'.
1180 2007-04-10, Version 3.11.4
1181 * dns plugin: Change the order of includes to make the plugin compile
1184 2007-03-30, Version 3.11.3
1185 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1186 of the unused `COLLECT_KSTAT'.
1188 2007-02-11, Version 3.11.2
1189 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1190 NULL-pointer may have been passed to `printf' which causes a
1191 segfault with some libcs.
1193 2007-02-10, Version 3.11.1
1194 * df plugin: Some wrong defines have been fixed so the plugin works
1195 under Solaris again.
1196 * dns plugin: The usage of a struct has been fixed to work with
1198 * processes plugin: Some missing defines have been added so the plugin
1199 compiles cleanly under FreeBSD and presumably other UNIXes.
1201 2006-12-22, Version 3.11.0
1202 * collectd: The new command line option `-P' makes it easier for
1203 distributors to change the location of PID-files.
1204 * collectd: The daemon shuts down faster now which makes it easier to
1205 write init.d-scripts for it.
1206 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1207 caused problems every now and then.
1208 * df plugin: New config options allow to ignore certain mountpoints,
1209 filesystem types or devices.
1210 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1211 and interprets it. It collects traffic as well as qtype, opcode and
1213 * email plugin: Sebastian Harl has contributed this plugin which
1214 counts received mails in categories (e. g. ham, spam, virus), spam
1215 score (as given by SpamAssassin) and check types.
1216 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1217 uses `mbmon' to gather information from sensors on the motherboard.
1218 * processes plugin: Collect detailed statistics for configured
1219 processes, that's process and thread count, CPU usage, resident
1220 segment size and pagefaults.
1221 * multimeter plugin: Peter Holik contributed a new plugin which
1222 queries multimeters.
1223 * sensors plugin: Lubos Stanek has put much effort into improving this
1224 plugin, including `extended naming', collection of voltage values
1225 and the possibility to ignore certain values.
1227 2006-12-21, Version 3.10.4
1228 * Max Kellermann has identified a bug in the server routine: When
1229 opening a socket fails the daemon will (re)try opening the socket in
1230 an endless loop, ultimately leading to a `EMFILE' error.
1232 2006-11-04, Version 3.10.3
1233 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1234 ntpd's reply was sent in more than one packet, the buffer size was
1235 calculated incorrectly, resulting in the reading of uninitialized or
1238 2006-11-01, Version 3.10.2
1239 * The sample config file has been improved.
1240 * Errors in the manpages have been corrected.
1241 * The ping-plugin now adds hosts during initialization, not during
1242 startup. This speeds up startup when no network connectivity is
1243 available. Also, the hosts are being added later when the network is
1245 * Improved BSD-support for the df-plugin.
1246 * Fixed syntax errors in the swap-plugin for Mac OS X.
1247 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1249 * Don't disable the mysql-plugin if connecting to the database fails
1250 during initialization. Instead, try again in increasing intervals.
1252 2006-07-19, Version 3.10.1
1253 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1254 the apcups cannot be reached, unconnected sockets will pile up and
1255 eventually lead to `Too many open files' errors.
1257 2006-07-09, Version 3.10.0
1258 * The `disk' plugin has been ported to Darwin.
1259 * The `battery' plugin should work on many Apple computers now.
1260 * The `traffic' plugin can now ignore certain interfaces. Also,
1261 statistics for sent/received packets and errors have been added.

1263 to Anthony Gialluca for contributing this plugin and providing me
1264 with a test environment :)
1265 * A plugin for monitoring an NTP instance and the local clock drift
1268 2006-06-25, Version 3.9.4
1269 * The Solaris code in the `swap' plugin has been changed to reflect
1270 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1272 * The debugging system has been fixed to work with the Sun libc.
1273 * When built without librrd the variable `operating_mode' could be
1274 uninitialized. Thanks to David Elliot for reporting the bug.
1276 2006-06-01, Version 3.9.3
1277 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1278 operating systems also profit from the changes, but I wasn't able to
1280 * Changed the build system to find the netinet-includes under FreeBSD
1281 and therefore successfully build the `liboping' library there.
1283 2006-05-09, Version 3.9.2
1284 * Applied a patch to the `liboping' library. Due to a bug in the
1285 sequence checking the `ping' plugin stopped working after
1286 approximately 7.6 days.
1288 2006-05-09, Version 3.8.5
1289 * Applied a patch to the `liboping' library. Due to a bug in the
1290 sequence checking the `ping' plugin stopped working after
1291 approximately 7.6 days.
1293 2006-04-21, Version 3.9.1
1294 * Build issues with Solaris and possible other architectures have been
1296 * Problems when building the `apache'-plugin without `libcurl' have
1298 * A bug in the `ping' plugin has been fixed. Sorry folks.
1300 2006-04-02, Version 3.9.0
1301 * A plugin to monitor the Apache webserver has been added.
1302 <http://httpd.apache.org/>
1303 * A plugin to collect statistics about virtual servers using VServer.
1304 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1306 * A plugin for wireless LAN cards has been added. It monitors signal
1307 strength, link quality and noise ratio..
1308 * A plugin for Apple hardware sensors has been added.
1309 * An option to compile collectd with different `step' and `heartbeat'
1310 settings has been added. The size of RRAs is no longer static but
1311 calculated based on the settings for `step' and `width'.
1312 * The `ping' plugin can now be configured to use a certain TTL.
1313 * A plugin to monitor the hardware sensors of Apple computers has been
1315 * The plugins `cpu', `memory', `processes' and `traffic' have been
1316 ported to Mach/Darwin (Mac OS X).
1317 * The `log mode' has been contributed by Christophe Kalt. It writes
1318 the data into text files rather than RRD files.
1320 2006-04-09, Version 3.8.4
1321 * Applied patch by Vincent Stehlé which improves the disk-name
1322 resolution in the `hddtemp' plugin for Linux systems.
1324 2006-04-02, Version 3.8.3
1325 * Applied a patch by James Byers: The MySQL plugin was not working
1326 with MySQL 5.0.2 or later.
1328 2006-03-14, Version 3.8.2
1329 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1330 the GNU libc, because it points to `/etc/fstab' rather than
1333 2006-03-13, Version 3.8.1
1334 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1335 * Fixes in the debian `postinst' and `init.d' scripts.
1337 2006-03-09, Version 3.8.0
1338 * The `ping' plugin no longer uses `libping' but a self written
1339 library named `liboping'. With this library it's possible to ping
1340 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1342 2006-02-18, Version 3.7.2
1343 * A simple bug in the `battery' plugin has been fixed. It should now
1344 work with ACPI based batteries as well. Thanks to Sebastian for
1346 * Fixing a bug that prevented collectd to be built without librrd.
1347 Thanks to Werner Heuser for reporting it.
1349 2006-02-04, Version 3.7.1
1350 * The new network code has been improved to build with older versions
1352 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1353 to Tommie Gannert for this patch.
1355 2006-01-30, Version 3.7.0
1356 * The `battery' plugin has been added. It collects information about
1358 * The MySQL plugin has been improved: It now writes two more RRD
1359 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1360 * The `cpufreq' plugin now reads another file since the file it did
1361 read so far causes much overhead in the kernel. Also, you need root
1362 to read the old file, but not to read the new one.
1363 * The `hddtemp' plugin can now be configured to connect to another
1364 address and/or port than localhost.
1365 * The `df' plugin now prefers `statvfs' over `statfs'.
1366 * The network code has been rewritten. collectd now supports unicast
1367 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1368 be set in the configfile.
1370 2006-01-24, Version 3.6.2
1371 * Due to a bug in the configfile handling collectd wouldn't start in
1372 client mode. This released fixes this.
1374 2006-01-20, Version 3.6.1
1375 * Due to a bug in `configure.in' all modules and the binary were
1376 linked against `libmysqlclient'. This issue is solved by this
1379 2006-01-17, Version 3.6.0
1380 * A config file has been added. This allows for loading only specific
1382 * A `df' plugin has been added.
1383 * A `mysql' plugin has been added.
1384 * The `ping' plugin doesn't entirely give up hope when a socket error
1385 occurred, but will back of and increase the intervals between tries.
1387 2006-01-21, Version 3.5.2
1388 * Fixed yet another bug in the signal handling.. Stupid typo..
1389 * Improved the ping plugin to not give up on socket errors (backport
1392 2005-12-18, Version 3.5.1
1393 * The PID-file is now deleted correctly when shutting down the daemon.
1394 * SIGINT and SIGTERM are now handled correctly.
1396 2005-12-16, Version 3.5.0 (Revision 326)
1397 * A bug in the `load' module under Solaris has been fixed.
1398 * The `users' module has been contributed by Sebastian Harl. It counts
1399 currently logged in users.
1400 * The CPU module now works under FreeBSD without the use of
1401 `libstatgrab', however SMP support is missing.
1402 * The default directories for the RRD files and the PID file now
1403 depend on the compile time setting of `localstatedir'.
1405 2005-11-15, Version 3.4.0 (Revision 236)
1406 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1407 from gentoo's bugzilla for writing the patch.
1408 * The build dependency for librrd has been removed. Binaries built
1409 without librrd are client-only and will multicast their value as
1410 with the `-c' argument.
1411 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1412 * The newly introduced `-f' switch prevents daemon initialization
1413 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1414 Barcellos for this patch.
1416 2005-11-04, Version 3.3.0 (Revision 216)
1417 * New modules have been added:
1418 - `serial', for monitoring traffic on the serial interfaces
1419 - `nfs', for graphing NFS procedure calls
1420 - `tape', traffic from/to tape devices
1421 * The memory.rrd now accepts more than 4Gig of memory.
1423 2005-10-26, Version 3.2.0 (Revision 200)
1424 * Support for graphing the processes has been added (thanks to Lyonel

1427 between polls up to one day.
1428 * The init.d files have been improved.
1429 * Problems with the spec file have been fixed.
1431 2005-10-16, Version 3.1.0 (Revision 194)
1432 * Added the `setsid' syscall to the startup code.
1433 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1435 2005-09-30, Version 3.0.0 (Revision 184)
1436 * The ability to send/receive data to/from the network (think
1437 multicast) has been added.
1438 * Modules have been split up into shared libraries can be loaded at
1439 runtime. The biggest advantage is that the core program doesn't need
1440 to be linked against an external library.
1441 * A patch by George Kargiotakis has been applied: It fixes the sensors
1442 behaviour then more than one sensor is being queried.
1444 2005-09-16, Version 2.1.0 (Revision 172)
1445 * A module for swap statistics has been added.
1447 2005-09-09, Version 2.0.0 (Revision 135)
1448 * Filenames can no longer be configured at program startup. The only
1449 options as of this version are the directory and ping hosts.
1450 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1451 Soft-IRQ statistics are added to `System'.
1452 * Diskstats now collect read and write bytes, not sectors.
1453 * Ping statistics can now be collected for more than one host. There
1454 is no default any more: If no host is given no host will be pinged.
1455 * A self-written patch for libping has been applied so it builds
1458 2005-09-01, Version 1.8.1 (Revision 123)
1459 * Much improved configure-script: libraries and features may now be
1461 * More detailed warnings/error messages when RRD update fails.
1463 2005-08-29, Version 1.8.0:
1464 * Support for collecting disk statistics under Solaris.
1466 2005-08-25, Version 1.7.0:
1467 * Support for libstatgrab[1] for load, memory usage and network
1468 traffic. CPU- and disk-usage are not (yet) supported, since
1469 libstatgrab returns insufficient information. I will contact the
1471 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1472 aren't necessarily counted linear which is now handled correctly.
1473 [1]: http://www.i-scream.org/libstatgrab/
