487 it. It is similar to the already existing PostgreSQL plugin but uses
488 libdbi to communicate with the database(s).
489 * interface plugin: Use the ignorelist framework when selecting /
490 ignoring interfaces. This allows one to use regular expressions to
491 select interfaces, too.

493 Thanks to Bruno Prémont for this patch.
494 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
496 * mysql plugin: Allow connecting to a database via the UNIX domain
497 socket, too. Thanks to Mirko Buffoni for the patch.
498 * network plugin: Further performance improvements for the receive
499 code. This hopefully will help very large setups.
500 * openvpn plugin: This new plugin collects statistics provided by the
501 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
502 * oracle plugin: This new plugin allows you to connect to an Oracle
503 database and use SQL to gather custom statistics from it. It is
504 similar to the already existing PostgreSQL plugin.
505 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
507 * perl plugin: Export the newly added plugin_write() to Perl plugins.
508 * perl plugin: Added support for `notification meta data'.
509 * perl plugin: Added support for the `filter chain' infrastructure by
510 allowing plugins to register `matches' and `targets'.
511 * postgresql plugin: The preferred configuration syntax has been
512 updated to be in line with the syntax used by the new dbi and oracle
513 plugins. The compatibility code for the old syntax is present.
514 Support for the new `Result' blocks and the interval parameter has
516 * processes plugin: Stacksize and virtual memory usage statistics have
517 been added. Portability fixes.
518 * rrdcached plugin: This new plugin uses the (still in development)
519 RRD accelerator daemon, rrdcached. This daemon works very similar to
520 the original rrdtool plugin of collectd, but adds some more nice
522 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
525 2009-05-09, Version 4.5.4
526 * Build system, various plugins: Many build fixes for FreeBSD,
527 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
528 for many fixes and providing a build system for many platforms,
529 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
530 providing an OpenBSD system.

537 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
538 Tomasz Pala for the patch.
539 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
541 * rrdtool plugin: Fix a possible race condition: If the network plugin
542 is initialized and dispatches a value before the rrdtool plugin is
543 initialized, the daemon may crash.
544 * memory plugin: Fix a potential problem under Solaris.
546 2009-02-22, Version 4.5.3
547 * build system: The check for libupsclient even when `pkg-config' is
549 * collectd: Fix error handling in the global cache.
550 * Collectd::Unixsock: Error handling has been improved.
551 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
553 * ipmi plugin: Fix an off-by-one error which could cause segmentation
554 faults. Thanks to Peter Holik for his patch.
555 * tcpconns plugin: An endianness problem has been fixed in the *BSD
556 code. Thanks to "thated" for reporting this.
558 2009-01-02, Version 4.5.2
559 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
560 file may be in both locations, especially when the database was
561 installed in a non-standard path. Thanks to Dusty Doris for
563 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
564 Solaris, in the configure script automatically.
565 * build system, tcpconns plugin: Check for `kvm_nlist' and
566 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
567 library with similar functions to the BSD variant, but doesn't
568 provide these necessary functions.
569 * collectd.conf(5): Various fixes and clarifications.
570 * collectd: Remove a GNUism (unnamed unions), thus improving
572 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
573 This solves portability problems, especially for Solaris.
574 * dns plugin: Fix a portability problem with NetBSD.
575 * filecount plugin: Fix an off-by-one error. This error may cause a
577 * network plugin: Fix the handling of `type' in the network protocol.
578 Due to a programming mistake, only 4 or 8 bytes would be copied to a
579 much larger buffer. This caused the `type' to be transferred much
580 more often than necessary. In some cases, e. g. the `cpu' and
581 `cpufreq' plugins being used at the same time, data may be corrupted
582 in those files. Thanks to Bruno Prémont for debugging and reporting
584 * processes plugin: Fix a possible segmentation fault when specifying
585 invalid configuration options.
586 * unixsock plugin: Make sure the initialization function is run only
587 once. This resolves a file descriptor leak under systems which run
588 the initialization more than once, such as Solaris.
590 2008-10-16, Version 4.5.1
591 * build system: Change `--enable-<plugin>' to abort with an error if
592 dependencies are not met. Thanks to Bruno Prémont for the patch.
593 Also, the poisoning of various string functions has been restricted
595 * collectd: Fix a memory leak in the global value cache. With every
596 *missing* value a couple of bytes would be leaked. Another memory
597 leak in the configuration handling code has been fixed. Thanks to
598 Niraj Tolia for reporting these issues.
599 * collectd: Fix an off-by-one error in the ignorelist functionality.
600 When using regular expressions, the last character would be missing,
601 possibly matching differently from what one would expect.
602 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
604 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
605 Linzberger for reporting the bug.
606 * iptables plugin: Fix an off-by-one error. If a string was just one
607 character too long, it was truncated instead of reporting an error.
608 * network plugin: Fix a memory leak in the configuration handling
609 code. Thanks to Niraj Tolia for reporting this issue.
610 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
611 * postgresql plugin: Don't reopen connection during reinitialization.
612 This fixes a bug under Solaris and potentially other platforms.
613 Missing calls to `PQclear' have been added, too. This fixes memory
614 leaks. Thanks to ``Admin'' for reporting these bugs.
615 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
617 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
618 problems with some `libc's. Thanks to Matthias Lay for reporting the
621 2008-09-04, Version 4.5.0
622 * collectd: Added the ability to flush certain identifiers.
623 * collectd: The concept of `notification meta data' has been
625 * filecount plugin: The new filecount plugin counts the number of
626 files in a directory and its subdirectories.
627 * ipmi plugin: Sensor names have been changed to ensure unique names.
628 Notifications upon added and removed sensors can now be generated.
629 * notify_desktop plugin: This new plugin sends notifications to the
630 X desktop using the structure defined in the `Desktop Notification
632 * notify_email plugin: This new plugin sends out notifications via
633 email, using the `esmtp' library.
634 * onewire plugin: The new experimental(!) onewire plugin reads values,
635 such as temperatures, from sensors connected to the computer via the
637 * perl plugin: Improved synchronized access to internal data structures
638 and fixed a possible dead-lock.
639 * perl plugin: Added the ability to flush certain identifiers and marked
640 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
642 * perl plugin: Added the ability to configure Perl plugins.
643 * postgresql plugin: The new postgresql plugin collects statistics
644 about or from a PostgreSQL database.
645 * processes plugin: The `ProcessMatch' option has been added.
646 * rrdtool plugin: Implement throttling of the `update queue' to lessen
648 * tcpconns plugin: This plugin has been ported to OpenBSD.
649 * thermal plugin: The new thermal plugin collects system temperatures
650 using Linux ACPI thermal zone data.
652 2009-01-02, Version 4.4.5
653 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
654 file may be in both locations, especially when the database was
655 installed in a non-standard path. Thanks to Dusty Doris for
657 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
658 Solaris, in the configure script automatically.
659 * collectd.conf(5): Various fixes and clarifications.
660 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
661 portability problems, especially for Solaris.
662 * dns plugin: Fix a portability problem with NetBSD.
663 * network plugin: Fix the handling of `type' in the network protocol.
664 Due to a programming mistake, only 4 or 8 bytes would be copied to a
665 much larger buffer. This caused the `type' to be transferred much
666 more often than necessary. In some cases, e. g. the `cpu' and
667 `cpufreq' plugins being used at the same time, data may be corrupted
668 in those files. Thanks to Bruno Prémont for debugging and reporting
670 * unixsock plugin: Make sure the initialization function is run only
671 once. This resolves a file descriptor leak under systems which run
672 the initialization more than once, such as Solaris.
674 2008-10-16, Version 4.4.4
675 * build system: Change `--enable-<plugin>' to abort with an error if
676 dependencies are not met. Thanks to Bruno Prémont for the patch.
677 Also, the poisoning of various string functions has been restricted
679 * collectd: Fix a memory leak in the global value cache. With every

681 leak in the configuration handling code has been fixed. Thanks to
682 Niraj Tolia for reporting these issues.
683 * collectd: Fix an off-by-one error in the ignorelist functionality.
684 When using regular expressions, the last character would be missing,
685 possibly matching differently from what one would expect.

688 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
689 Linzberger for reporting the bug.
690 * network plugin: Fix a memory leak in the configuration handling
691 code. Thanks to Niraj Tolia for reporting this issue.
692 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
693 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
694 problems with some `libc's. Thanks to Matthias Lay for reporting the
697 2008-09-01, Version 4.4.3
698 * collectd: Fix a memory leak in the threshold checking code.

706 * collectd: Try even harder to determine the endianess of the
707 architecture collectd is being built on.
708 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
710 * dns plugin: Fix compilation errors with BIND versions 19991001
712 * network plugin: Bugfix in the init routine: The init function
713 cleared a buffer regardless of its contents. This could lead to lost
714 values under Solaris.
715 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
716 * vserver plugin: Remove usage of the thread-unsafe `readdir'
718 * wireless plugin: Work around incorrect noise and power values
719 returned by some broken drivers.
721 2008-06-03, Version 4.4.1
722 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
723 to kyrone for reporting this.
724 * collectd: Fixed min/max output in notifications generated by
726 * collectd-nagios: Fix the protocol used to communicate with the
728 * perl plugin: Fail noisily, but don't shutdown the daemon, if
729 initialization has errors. An issue with Perl 5.10 has been fixed.
730 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
731 René Rebe and Siegmund Gorr for reporting this.
733 2008-05-06, Version 4.4.0
734 * collectd: Internal code cleanups.
735 * collectd: Added support for a `Flush' command in the unixsock and
736 exec plugins. This command can be used to force a plugin (or all) to
737 flush its values to disk.
738 * collectd: Thresholds can now be configured to apply to one data
739 source only, making it possible to configure different thresholds
740 for each data source.
741 * apache, nginx plugins: Added the possibility to disable host and/or
743 * ascent plugin: The new ascent plugin reads and parses the statistics
744 page of an Ascent server.
745 * cpu plugin: Support for the statgrab library has been added.
746 * disk plugin: The possibility to ignore certain disks or collect only
747 specific disks has been added.
748 * disk plugin: Support for the statgrab library has been added.
749 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
750 sensor values via IPMI, the intelligent platform management
752 * iptables plugin: The iptc library that is used by the iptables
753 plugin has been added to the distribution, because it is not
754 provided by all distributions and removed from at least one.
755 * powerdns plugin: The new powerdns plugin reads statistics from an
756 authoritative or a recursing PowerDNS name server.
757 * rrdtool plugin: The size of the files generated with the default
758 configuration has been decreased.
759 * tail plugin: The new tail plugin can be used to gather statistics by
760 continuously reading from log files.
761 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
762 TeamSpeak2 server and collects statistics about the number of users
763 and number of channels.
764 * users plugin: Support for the statgrab library has been added.
765 * vmem plugin: The new vmem plugin collects very detailed statistics
766 about the virtual memory subsystem of Linux.

787 * build system: Improved detection of several libraries, especially if
788 they are in non-standard paths.
789 * build system: Portability fixes: Automatically define "_REENTRANT"
790 if the libc expects it.
791 * collectd: Error and warning messages have been improved.
792 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
794 * apache plugin: Allocate new memory when reading a webpage instead of
795 using a buffer of static size.
796 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
798 * hddtemp plugin: Error and warning messages have been improved.
799 * sensors plugin: Fix sensor collection for some chip types.
801 2008-03-29, Version 4.3.2
802 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
803 `Persist' threshold options.
804 * collectd: Fix handling of missing values in the global value cache.
805 * collectd: Improved error messages when parsing the configuration.

810 2008-03-05, Version 4.3.1
811 * exec plugin: Set supplementary group IDs.
813 + Use `memcpy' when constructing/parsing a package to avoid
814 alignment problems on weird architectures, such as Sparc.
815 + Translate doubles to/from the x86 byte representation to ensure
816 cross-platform compatibility.
817 * ping plugin: Correct the handling of the `TTL' setting.
818 * swap plugin: Reapply a patch for Solaris.
819 * tcpconns plugin: Portability improvements.
821 2008-02-18, Version 4.3.0
822 * collectd: Notifications have been added to the daemon. Notifications
823 are status messages that may be associated with a data instance.
824 * collectd: Threshold checking has been added to the daemon. This
825 means that you can configure threshold values for each data
826 instance. If this threshold is exceeded a notification will be
828 * collectd: The new `FQDNLookup' option tells the daemon to use the
829 full qualified domain name as the hostname, not just the host part
830 es returned by `gethostname(2)'.
831 * collectd: Support for more than one `TypesDB' file has been added.
832 This is useful when one such file is included in a package but one
833 wants to add custom type definitions.
834 * collectd: The `Include' config option has been expanded to handle
835 entire directories and shell wildcards.
836 * collectdmon: The new `collectdmon' binary detects when collectd
837 terminates and automatically restarts it again.
838 * csv plugin: The CSV plugin is now able to store counter values as a
839 rate, using the `StoreRates' configuration option.
840 * exec plugin: Handling of notifications has been added and the
841 ability to pass arguments to the executed programs has been added.
842 * hddtemp plugin: The new `TranslateDevicename' option lets you
843 disable the translation from device names to major-minor-numbers.
844 * logfile plugin: Handling of notifications has been added.
845 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
846 domain name lookups in this plugin.
847 * perl plugin: Many internal changes added support for handling multiple
848 threads making the plugin reasonably usable inside collectd. The API has
849 been extended to support notifications and export global variables to
850 Perl plugins; callbacks now have to be identified by name rather than a
851 pointer to a subroutine. The plugin is no longer experimental.
852 * uuid plugin: The new UUID plugin sets the hostname to an unique
853 identifier for this host. This is meant for setups where each client
854 may migrate to another physical host, possibly going through one or
855 more name changes in the process. Thanks to Richard Jones from
856 Red Hat's Emerging Technology group for this plugin.
857 * libvirt: The new libvirt plugin uses the `libvirt' library to query
858 CPU, disk and network statistics about guest systems on the same
859 physical server. Thanks to Richard Jones from Red Hat's Emerging
860 Technology group for this plugin.
862 2008-04-22, Version 4.2.7
863 * build system: Improved detection of several libraries, especially if
864 they are in non-standard paths.
865 * build system: Portability fixes: Automatically define "_REENTRANT"
866 if the libc expects it.
867 * collectd: Error and warning messages have been improved.
868 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
870 * apache plugin: Allocate new memory when reading a webpage instead of
871 using a buffer of static size.
872 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
874 * hddtemp plugin: Error and warning messages have been improved.

883 2008-03-04, Version 4.2.5
884 * apache plugin: Improved initialization and error messages.
885 * exec plugin: Set supplementary group IDs.
887 + Create separate threads for reading from the socket and parsing
888 and dispatching incoming packets. Versions prior to this may have
889 problems in high-load situations, where the socket receive buffers
890 overflows, resulting in gaps in the data.
891 + Use `memcpy' when constructing/parsing a package to avoid
892 alignment problems on weird architectures, such as Sparc.
893 + Translate doubles to/from the x86 byte representation to ensure
894 cross-platform compatibility.
895 * ping plugin: Correct the handling of the `TTL' setting.
896 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
897 * swap plugin: Reapply a patch for Solaris.
898 * tcpconns plugin: Portability improvements.
900 2008-01-21, Version 4.2.4
901 * unixsock plugin: A bug in the unixsock plugin caused it not to set
902 the permission on the socket as documented in the manpage. Thanks to
903 Evgeny Chukreev for fixing this issue.
904 * collectd: The documentation has been improved.
906 2007-12-28, Version 4.2.3
907 * sensors plugin: Updated the plugin to build and work with version 3
908 of the libsensors library.
910 2007-12-15, Version 4.2.2
911 * nginx plugin: Incorrect comparison of strings lead to a segfault
912 when using the plugin. Thanks to Saulius Grigaliunas for fixing
914 * logfile plugin: The config option `Timestamp' was handled
915 incorrectly and basically always active. Thanks to Luke Heberling
918 2007-11-08, Version 4.2.1
919 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
921 * snmp plugin: Fix a memory leak.
923 2007-10-27, Version 4.2.0
924 * collectd: The new config option `Include' lets you include other
925 configfiles and thus split up your config into smaller parts. This
926 may be especially interesting for the snmp plugin to keep the data
927 definitions separate from the host definitions.
928 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
929 (number of connections, octets and packets for each service and
930 destination). Thanks to Sebastian Harl for this plugin.
931 * memcached plugin: The new `memcached' plugin connects to a memcached
932 daemon process and collects statistics of this distributed caching
933 system. Thanks to Antony Dovgal for contributing this plugin.
934 * nginx plugin: The new `nginx' plugin reads the status page of an
935 nginx daemon and saves the handled connections and requests.
936 * perl plugin: Many changes, including the added `EnableDebugger'
937 config option which lets you debug your Perl plugins more easily.
938 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
939 be more thread-safe otherwise by locking calls to the library.
940 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
941 correct the values returned by SNMP-agents. If a <data> block is
942 defined as `table' the instance is now optional. The sequence number
943 is used as the type-instance in this case. The new `InstancePrefix'
944 option allows to add arbitrary prefixes to the type-instance.
945 * tcpconns plugin: The new `tcpconns' plugin collects the number of
946 certain TCP connections and what state they're in. This can be used
947 to see how many connections your FTP server has to handle or how
948 many outgoing connections your mailserver has open.
950 2008-01-11, Version 4.1.6
951 * unixsock plugin: A bug in the unixsock plugin caused it not to set
952 the permission on the socket as documented in the manpage. Thanks to
953 Evgeny Chukreev for fixing this issue.

960 of the libsensors library.
962 2007-11-08, Version 4.1.4
963 * Build system: Improve detection of the rrd library, especially if
964 it's in a non-standard location.
965 * Build system: A bug when parsing the argument for
966 `--with-libnetsnmp' has been fixed.
967 * collectd: Implement `strerror_r' if the libc doesn't provide it.
968 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
969 a deadlock or delay when shutting down the daemon.
970 * snmp plugin: Fix a memory leak.
972 2007-10-24, Version 4.1.3
973 * collectd: A build issue under Solaris has been resolved by renaming
975 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
976 be more thread-safe otherwise by locking calls to the library.
978 2007-09-28, Version 4.1.2
979 * apcups plugin: Fix reporting of the `load percent' data.
980 * wireless plugin: Correct the handling of cards returning signal and
981 noise quality as percentage.
982 * perl plugin: Fix a possible buffer overflow in get_module_name().

1001 whatever the client thinks is `now'..
1003 2007-09-01, Version 4.1.0
1004 * Build system: The build system has been changed to automatically
1005 disable all plugins, which are missing dependencies. The dependency
1006 checking has been removed from the plugins themselves to remove
1008 * Flexible interval: The interval of collected data is now sent along
1009 with the data itself over the network, so that the interval-settings
1010 of server and clients no longer needs to match.
1011 * netlink plugin: The new `netlink' plugin connects to the Linux
1012 kernel using a netlink socket and uses it to query information about
1013 interfaces, qdiscs and classes.
1014 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1015 to not block data collection.
1016 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1017 network devices, such as switches, routers, thermometers, rack
1018 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1020 * unixsock plugin: Added the `LISTVAL' command.
1021 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1022 of music played with xmms.

1030 2007-09-12, Version 4.0.8
1031 * collectd: The `sstrerror' function was improved to work correctly
1032 with the broken GNU version of `strerror_r'.
1033 * collectd: Write an error message to STDERR when loading of a plugin
1035 * apcups plugin: Fix the `types' used to submit the values: They still
1036 has an `apcups_' prefix which doesn't work anymore.
1037 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1038 whatever the client thinks is `now'..
1040 2007-08-26, Version 4.0.7
1041 * documentation: Some typos have been fixed and some information has
1043 * build system: Many fixes for detecting libraries in unusual places,
1044 such as on RedHat systems. The affected libraries are `libcurl',
1045 `libmysql', and `libupsclient'.
1046 * network plugin: Allow the `Port' option to be specified as a number
1047 (i. e. without quotes).
1048 * nut plugin: A fix allows linking the nut plugin against
1049 libupsclient, version >= 2.2.0.
1050 * processes plugin: Fix a potential segmentation fault.
1052 2007-07-30, Version 4.0.6
1053 * sensors plugin: Fix the ignorelist functionality: Only the `type
1054 instance' was used to match against the list, but the documentation
1055 told otherwise. This release fixes the code, so it complies with the
1057 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1058 configuration messages will end up in the logging facility.
1059 * conrtib/fedora: The contributed specfile for Fedora has been
1062 2007-07-05, Version 4.0.5
1063 * Portability: More fixes for OpenBSD have been included.

1082 they're given in numerically form.
1084 2007-06-07, Version 4.0.1
1085 * iptables plugin: A bug in the configuration routine has been fixed.
1086 Setting a comment in the configfile will no longer cause a
1089 2007-06-03, Version 4.0.0
1090 * collectd: The plugin-infrastructure has been changed to allow for
1091 more types of plugins, namely `write' and `log' plugins.
1092 * collectd: The read-function has been changed to read many plugins in
1093 parallel, using threads. Thus, plugins generally need to use
1094 thread-safe functions from now on.
1095 * collectd: The '-t' command line options allows to perform syntax tests
1096 of the configuration file and exit immediately.
1097 * csv plugin: The new `csv' plugin handles output to `comma separated
1099 * rrdtool plugin: The new `rrdtool' plugin handles output to
1100 RRD-files. Data can be cached to combine multiple updates into one
1101 write to increase IO-performance.
1102 * network plugin: The new `network' plugin handles IO via the network.
1103 It implements a different, much more extensible protocol which can
1104 combine many values in one packet, decreasing the number of UDP-
1105 packets being sent. It can read from and send to the network and
1106 with the appropriate configuration even forward packets to other
1108 * unixsock plugin: The new `unixsock' plugin provides an interface to
1109 communicate with the daemon while it is running. Right now the
1110 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1112 * perl plugin: The new `perl' plugin allows you to write extensions
1113 for collectd in the scripting-language Perl.
1114 * logfile plugin: The new `logfile' plugin writes logmessages to files
1115 or STDOUT or STDERR.
1116 * syslog plugin: The new `syslog' plugin sends logmessages to the
1117 system's syslog daemon.
1118 * entropy plugin: The new `entropy' plugin collects the amount of
1119 entropy currently being available to the system.

1121 back values provided by the forked processes.
1122 * iptables plugin: The new `iptables' plugin reads counters from
1123 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1125 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1126 to Peter Holik for contributing this plugin.
1127 * nut plugin: The new `nut' plugin connects the upsd of the `network
1128 ups tools' and reads information about the connected UPS.
1129 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1130 connections) field was added by Florent Monbillard.
1131 * collectd-nagios: The new `collectd-nagios' binary queries values
1132 from collectd, parses them and exits according to Nagios-standards.
1133 * manpages: The manpages have been improved a lot.
1135 2007-09-28, Version 3.11.7
1136 * wireless plugin: Correct the handling of cards returning signal and
1137 noise quality as percentage.
1139 2007-08-31, Version 3.11.6
1140 * processes plugin: Fix a potential segmentation fault.
1142 2007-05-29, Version 3.11.5
1143 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1144 * ntpd plugin: Fix a potential buffer overflow.
1145 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1146 were accounted as `zombies'.
1148 2007-04-10, Version 3.11.4
1149 * dns plugin: Change the order of includes to make the plugin compile
1152 2007-03-30, Version 3.11.3
1153 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1154 of the unused `COLLECT_KSTAT'.
1156 2007-02-11, Version 3.11.2
1157 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1158 NULL-pointer may have been passed to `printf' which causes a
1159 segfault with some libcs.
1161 2007-02-10, Version 3.11.1
1162 * df plugin: Some wrong defines have been fixed so the plugin works
1163 under Solaris again.
1164 * dns plugin: The usage of a struct has been fixed to work with
1166 * processes plugin: Some missing defines have been added so the plugin
1167 compiles cleanly under FreeBSD and presumably other UNIXes.
1169 2006-12-22, Version 3.11.0
1170 * collectd: The new command line option `-P' makes it easier for
1171 distributors to change the location of PID-files.
1172 * collectd: The daemon shuts down faster now which makes it easier to
1173 write init.d-scripts for it.
1174 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1175 caused problems every now and then.
1176 * df plugin: New config options allow to ignore certain mountpoints,
1177 filesystem types or devices.
1178 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1179 and interprets it. It collects traffic as well as qtype, opcode and
1181 * email plugin: Sebastian Harl has contributed this plugin which
1182 counts received mails in categories (e. g. ham, spam, virus), spam
1183 score (as given by SpamAssassin) and check types.
1184 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1185 uses `mbmon' to gather information from sensors on the motherboard.
1186 * processes plugin: Collect detailed statistics for configured
1187 processes, that's process and thread count, CPU usage, resident
1188 segment size and pagefaults.
1189 * multimeter plugin: Peter Holik contributed a new plugin which
1190 queries multimeters.
1191 * sensors plugin: Lubos Stanek has put much effort into improving this
1192 plugin, including `extended naming', collection of voltage values
1193 and the possibility to ignore certain values.
1195 2006-12-21, Version 3.10.4
1196 * Max Kellermann has identified a bug in the server routine: When
1197 opening a socket fails the daemon will (re)try opening the socket in
1198 an endless loop, ultimately leading to a `EMFILE' error.
1200 2006-11-04, Version 3.10.3
1201 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1202 ntpd's reply was sent in more than one packet, the buffer size was
1203 calculated incorrectly, resulting in the reading of uninitialized or
1206 2006-11-01, Version 3.10.2
1207 * The sample config file has been improved.
1208 * Errors in the manpages have been corrected.
1209 * The ping-plugin now adds hosts during initialization, not during
1210 startup. This speeds up startup when no network connectivity is
1211 available. Also, the hosts are being added later when the network is
1213 * Improved BSD-support for the df-plugin.
1214 * Fixed syntax errors in the swap-plugin for Mac OS X.
1215 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1217 * Don't disable the mysql-plugin if connecting to the database fails
1218 during initialization. Instead, try again in increasing intervals.
1220 2006-07-19, Version 3.10.1
1221 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1222 the apcups cannot be reached, unconnected sockets will pile up and
1223 eventually lead to `Too many open files' errors.
1225 2006-07-09, Version 3.10.0
1226 * The `disk' plugin has been ported to Darwin.
1227 * The `battery' plugin should work on many Apple computers now.
1228 * The `traffic' plugin can now ignore certain interfaces. Also,
1229 statistics for sent/received packets and errors have been added.
1230 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1231 to Anthony Gialluca for contributing this plugin and providing me
1232 with a test environment :)
1233 * A plugin for monitoring an NTP instance and the local clock drift
1236 2006-06-25, Version 3.9.4
1237 * The Solaris code in the `swap' plugin has been changed to reflect
1238 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1240 * The debugging system has been fixed to work with the Sun libc.
1241 * When built without librrd the variable `operating_mode' could be
1242 uninitialized. Thanks to David Elliot for reporting the bug.
1244 2006-06-01, Version 3.9.3
1245 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1246 operating systems also profit from the changes, but I wasn't able to
1248 * Changed the build system to find the netinet-includes under FreeBSD
1249 and therefore successfully build the `liboping' library there.
1251 2006-05-09, Version 3.9.2
1252 * Applied a patch to the `liboping' library. Due to a bug in the
1253 sequence checking the `ping' plugin stopped working after
1254 approximately 7.6 days.
1256 2006-05-09, Version 3.8.5
1257 * Applied a patch to the `liboping' library. Due to a bug in the
1258 sequence checking the `ping' plugin stopped working after
1259 approximately 7.6 days.
1261 2006-04-21, Version 3.9.1
1262 * Build issues with Solaris and possible other architectures have been
1264 * Problems when building the `apache'-plugin without `libcurl' have
1266 * A bug in the `ping' plugin has been fixed. Sorry folks.
1268 2006-04-02, Version 3.9.0
1269 * A plugin to monitor the Apache webserver has been added.
1270 <http://httpd.apache.org/>
1271 * A plugin to collect statistics about virtual servers using VServer.
1272 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1274 * A plugin for wireless LAN cards has been added. It monitors signal
1275 strength, link quality and noise ratio..
1276 * A plugin for Apple hardware sensors has been added.
1277 * An option to compile collectd with different `step' and `heartbeat'
1278 settings has been added. The size of RRAs is no longer static but
1279 calculated based on the settings for `step' and `width'.
1280 * The `ping' plugin can now be configured to use a certain TTL.
1281 * A plugin to monitor the hardware sensors of Apple computers has been
1283 * The plugins `cpu', `memory', `processes' and `traffic' have been
1284 ported to Mach/Darwin (Mac OS X).
1285 * The `log mode' has been contributed by Christophe Kalt. It writes
1286 the data into text files rather than RRD files.
1288 2006-04-09, Version 3.8.4
1289 * Applied patch by Vincent Stehlé which improves the disk-name
1290 resolution in the `hddtemp' plugin for Linux systems.
1292 2006-04-02, Version 3.8.3
1293 * Applied a patch by James Byers: The MySQL plugin was not working
1294 with MySQL 5.0.2 or later.
1296 2006-03-14, Version 3.8.2
1297 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1298 the GNU libc, because it points to `/etc/fstab' rather than
1301 2006-03-13, Version 3.8.1
1302 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1303 * Fixes in the debian `postinst' and `init.d' scripts.
1305 2006-03-09, Version 3.8.0
1306 * The `ping' plugin no longer uses `libping' but a self written
1307 library named `liboping'. With this library it's possible to ping
1308 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1310 2006-02-18, Version 3.7.2
1311 * A simple bug in the `battery' plugin has been fixed. It should now
1312 work with ACPI based batteries as well. Thanks to Sebastian for
1314 * Fixing a bug that prevented collectd to be built without librrd.
1315 Thanks to Werner Heuser for reporting it.
1317 2006-02-04, Version 3.7.1
1318 * The new network code has been improved to build with older versions
1320 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1321 to Tommie Gannert for this patch.
1323 2006-01-30, Version 3.7.0
1324 * The `battery' plugin has been added. It collects information about
1326 * The MySQL plugin has been improved: It now writes two more RRD
1327 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1328 * The `cpufreq' plugin now reads another file since the file it did
1329 read so far causes much overhead in the kernel. Also, you need root
1330 to read the old file, but not to read the new one.
1331 * The `hddtemp' plugin can now be configured to connect to another
1332 address and/or port than localhost.
1333 * The `df' plugin now prefers `statvfs' over `statfs'.
1334 * The network code has been rewritten. collectd now supports unicast
1335 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1336 be set in the configfile.
1338 2006-01-24, Version 3.6.2
1339 * Due to a bug in the configfile handling collectd wouldn't start in
1340 client mode. This released fixes this.
1342 2006-01-20, Version 3.6.1
1343 * Due to a bug in `configure.in' all modules and the binary were
1344 linked against `libmysqlclient'. This issue is solved by this
1347 2006-01-17, Version 3.6.0
1348 * A config file has been added. This allows for loading only specific
1350 * A `df' plugin has been added.
1351 * A `mysql' plugin has been added.
1352 * The `ping' plugin doesn't entirely give up hope when a socket error
1353 occurred, but will back of and increase the intervals between tries.
1355 2006-01-21, Version 3.5.2
1356 * Fixed yet another bug in the signal handling.. Stupid typo..
1357 * Improved the ping plugin to not give up on socket errors (backport
1360 2005-12-18, Version 3.5.1
1361 * The PID-file is now deleted correctly when shutting down the daemon.
1362 * SIGINT and SIGTERM are now handled correctly.
1364 2005-12-16, Version 3.5.0 (Revision 326)
1365 * A bug in the `load' module under Solaris has been fixed.
1366 * The `users' module has been contributed by Sebastian Harl. It counts
1367 currently logged in users.
1368 * The CPU module now works under FreeBSD without the use of
1369 `libstatgrab', however SMP support is missing.
1370 * The default directories for the RRD files and the PID file now
1371 depend on the compile time setting of `localstatedir'.
1373 2005-11-15, Version 3.4.0 (Revision 236)
1374 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1375 from gentoo's bugzilla for writing the patch.
1376 * The build dependency for librrd has been removed. Binaries built
1377 without librrd are client-only and will multicast their value as
1378 with the `-c' argument.
1379 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1380 * The newly introduced `-f' switch prevents daemon initialization
1381 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1382 Barcellos for this patch.
1384 2005-11-04, Version 3.3.0 (Revision 216)
1385 * New modules have been added:
1386 - `serial', for monitoring traffic on the serial interfaces
1387 - `nfs', for graphing NFS procedure calls
1388 - `tape', traffic from/to tape devices

1395 between polls up to one day.
1396 * The init.d files have been improved.
1397 * Problems with the spec file have been fixed.
1399 2005-10-16, Version 3.1.0 (Revision 194)
1400 * Added the `setsid' syscall to the startup code.
1401 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1403 2005-09-30, Version 3.0.0 (Revision 184)
1404 * The ability to send/receive data to/from the network (think
1405 multicast) has been added.
1406 * Modules have been split up into shared libraries can be loaded at
1407 runtime. The biggest advantage is that the core program doesn't need
1408 to be linked against an external library.
1409 * A patch by George Kargiotakis has been applied: It fixes the sensors
1410 behaviour then more than one sensor is being queried.
1412 2005-09-16, Version 2.1.0 (Revision 172)
1413 * A module for swap statistics has been added.
1415 2005-09-09, Version 2.0.0 (Revision 135)
1416 * Filenames can no longer be configured at program startup. The only
1417 options as of this version are the directory and ping hosts.
1418 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1419 Soft-IRQ statistics are added to `System'.
1420 * Diskstats now collect read and write bytes, not sectors.
1421 * Ping statistics can now be collected for more than one host. There
1422 is no default any more: If no host is given no host will be pinged.
1423 * A self-written patch for libping has been applied so it builds
1426 2005-09-01, Version 1.8.1 (Revision 123)
1427 * Much improved configure-script: libraries and features may now be
1429 * More detailed warnings/error messages when RRD update fails.
1431 2005-08-29, Version 1.8.0:
1432 * Support for collecting disk statistics under Solaris.
1434 2005-08-25, Version 1.7.0:
1435 * Support for libstatgrab[1] for load, memory usage and network
1436 traffic. CPU- and disk-usage are not (yet) supported, since
1437 libstatgrab returns insufficient information. I will contact the
1439 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1440 aren't necessarily counted linear which is now handled correctly.
1441 [1]: http://www.i-scream.org/libstatgrab/
1443 2005-08-21, Version 1.6.0:
1444 * Basic support for Solaris: System load and cpu-usage can be
1445 collected under Solaris, too. Other stats will follow later.
1446 * Many fixes in the autoconf-script
1447 * Collection/Museum scripts have been added under contrib/museum
1448 * collectd may now be started in unprivileged mode, though ping
1449 statistics will not work.
1451 2005-07-17, Version 1.5.1:
1452 * Diskstats-RRDs now use major/minor for naming. Some systems have
1453 weird strings as disk-names..
1455 2005-07-17, Version 1.5:
1456 * A new module, diskstats, has been added. It collects information
1457 about the disks and partitions.
1459 2005-07-11, Version 1.4.2:
1460 * The meminfo module has been changed to work with more platforms
1461 and/or kernel versions.
1463 2005-07-10, Version 1.4.1: Correct traffic stats
1464 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1465 forgot to correct when I changed that module.
1467 2005-07-09, Version 1.4: More traffic stats
1468 * Traffic is now collected for all interfaces that can be found
1469 * Temperature-statistics are read from lm-sensors if available
1471 2005-07-08, Version 1.3: CPU stats
1472 * Collecting CPU statistics now
1474 2005-07-12, Version 1.2: Using syslog
