70 runtime has been fixed.
72 2012-02-19, Version 4.10.6

541 the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
542 (ZFS). Thanks to Anthony Dewhurst for the patch.
543 * empty_counter match: The new Empty Counter match matches value
544 lists, where at least one data source is of type COUNTER and the
545 counter value of all counter data sources is zero.
547 2009-12-18, Version 4.7.5
548 * Build system, java plugin: Don't use “find -L” to search for Java

561 * unixsock plugin: A memory leak in the LISTVAL command has been
562 fixed. Thanks to Ben Knight for his patch.
564 2009-10-03, Version 4.7.4
565 * Build system: Issues when building the iptables plugin have been
566 fixed.
567 * exec plugin: Clear the signal block mask before calling exec(2).
568 * perl plugin: Declare the “environ” variable. This solves build
569 issues on some platforms.

573 descriptor handling.
575 2009-09-13, Version 4.7.3
576 * collectd: Fix a possible but very rare invalid “free” in the caching
577 code. Thanks to Sebastian Harl for the patch.
578 * collectd: Remove old values when a cache entry is marked as missing.
579 This way the “GETVAL” command of the UnixSock plugin doesn't return
580 old, no longer valid values when this happens. Thanks to Andrés J.
581 Díaz for the patch.
582 * collectd: The “plugin_unregister_read” function has been fixed.
583 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
584 to follow redirects. Thanks to Joey Hess for reporting this bug.

587 Hess for reporting this bug.
588 * iptables plugin: Support for the new libiptc API has been added.
589 Thanks to Sebastian Harl for the patch. The build system has been
590 updated to the plugin only includes the shipped header files when it
591 is linked with the shipped library, too.
592 * java plugin: Delay creating the JVM until after the daemon has
593 forked. The JVM internally creates threads that are lost when
594 forking. This means that Java-based plugins are now configured
595 during the init-phase, i. e. later than other plugins.
596 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
597 to Alan Pevec for the patch.
598 * network plugin: Fix the handling of the “CacheFlush” option: The

620 details have been added to the configuration summary. Support for
621 libtool 2.2 has been added.
622 * collectd: Two bugs with the threshold checking have been fixed. The
623 first one prevented thresholds to be checked at all, the second one
624 caused wrong behavior with the persistency option. Thanks to Andrés
625 J. Díaz for fixing these problems.
626 * collectd: Handling of the `Include' configuration option has been
627 fixed.
628 * rrdtool plugin: Make sure initialization is run only once. This
629 resolves problems under Solaris and potentially other systems.
630 Thanks to Amit Gupta for reporting this bug.
631 * java plugin: Make it possible to use dots ('.') instead of slashes
632 ('/') as the class separator. Thanks to Randy Rizun for pointing
633 this out.

643 tracking table size. Thanks to Tomasz Pala for the patch.
644 * fscache plugin: The new fscache plugin collects statistics about
645 Linux' file-system based caching framework. Thanks to Edward
646 Konetzko for the patch.
647 * gmond plugin: The new gmond plugin can receive and interpret
648 multicast traffic from Ganglia's gmond daemon.
649 * java plugin: The new java plugin exports the collectd API to Java,
650 making it possible to write extensions to collectd in Java.
651 * memcachec plugin: The new memcachec plugin queries data from a
652 memcached daemon and parses it similar to the cURL plugin. Thanks to
653 Doug MacEachern for the initial code.
654 * memcached plugin: Support for connections over UNIX domain sockets
655 has been added. Thanks to Franck Lombardi for the patch.
656 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

668 plugin must no longer be a multiple of the global interval.
669 * table plugin: The new Table plugin provides parsing for table-like
670 structured files, such as many files beneath /proc.
671 * ted plugin: The new TED plugin reads power consumption measurements
672 from “The Energy Detective” (TED). Thanks to Eric Reed for this
673 plugin.
674 * onewire plugin: The new `Interval' option allows collecting
675 information from OneWire sensors at arbitrary intervals.
676 * ping plugin: Support for collecting the drop rate and standard
677 deviation of round-trip times has been added.

679 uptime. Thanks to Marco Chiappero for the patch.
681 2009-09-10, Version 4.6.5
682 * collectd: Remove old values when a cache entry is marked as missing.
683 This way the “GETVAL” command of the UnixSock plugin doesn't return
684 old, no longer valid values when this happens. Thanks to Andrés J.
685 Díaz for the patch.
686 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
687 to follow redirects. Thanks to Joey Hess for reporting this bug.

696 to Alan Pevec for the patch.
697 * powerdns plugin: Set a timeout when reading data from the datagram
698 socket. Handling of the “LocalSocket” option has been fixed. An
699 incorrectly used “type” has been corrected. Thanks to Luke Heberling
700 for his patches.

708 for reporting the bug.
710 2009-06-02, Version 4.6.3
711 * Build system, various plugins: Many build fixes for FreeBSD,
712 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
713 for many fixes and providing a build system for many platforms,
714 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
715 providing an OpenBSD system.
716 * collectd: Two bugs with the threshold checking have been fixed. The
717 first one prevented thresholds to be checked at all, the second one
718 caused wrong behavior with the persistency option. Thanks to Andrés
719 J. Díaz for fixing these problems.
720 * collectd: Handling of the `Include' configuration option has been
721 fixed.
722 * battery plugin: Don't complain about a missing directory every
723 interval.
724 * exec plugin: Allow executed programs to close STDERR. Thanks to
725 Thorsten von Eicken for reporting this problem.
726 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
727 Tomasz Pala for the patch.
728 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
729 the patch.
730 * memory plugin: Fix a potential problem under Solaris.
731 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
732 to Doug MacEachern for the patch.
734 2009-03-18, Version 4.6.2
735 * collectd: Some Solaris utility code has been improved.
736 * filter subsystem: Allow `Chains' without default targets.
737 * liboping: A patch to comply with strict aliasing rules has been
738 added.
739 * timediff match: Fix a typo: The match was registered with a wrong
740 name which prevented this match to be used as documented. Thanks to
741 Bruno Prémont for finding this problem.
742 * bind plugin: Fix collection of the cached RR sets. The number of RR
743 sets currently in the cache was collected as a counter value, which
744 is nonsense. Thanks to Bruno Prémont for implementing this.
745 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
746 primarily BSDs, don't take it well and crash.
747 * oracle plugin: Portability to 64 bit systems has been improved.
748 * postgresql plugin: The default configuration has been improved.
749 * rrdtool plugin: Fix a possible race condition: If the network plugin
750 is brought and dispatches a value before the rrdtool plugin is
751 initialized, the daemon may crash.
753 2009-02-22, Version 4.6.1
754 * collectd: Many documentation fixes.
755 * Collectd::Unixsock: Error handling has been improved.
756 * regex match: Don't link with the PCRE library.
757 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
758 for finding and fixing most of them.
759 * ipmi plugin: Fix an off-by-one error which could cause segmentation
760 faults. Thanks to Peter Holik for his patch.
762 2009-02-16, Version 4.6.0
763 * collectd: Added the `filter chain' infrastructure, which allows the
764 user to use `matches' and `targets' to control value processing.
765 * collectd: The new `-T' command line argument allows more in-depth
766 testing of a configuration. Thanks to Doug MacEachern for the patch.
767 * collectd-nagios: The Nagios integration command has been updated to
768 use libcollectdclient. The `percentage' aggregation function has
769 been added. Thanks to Fabian Linzberger for the patch.
770 * libcollectdclient: A library which abstracts communication with the
771 unixsock plugin for clients has been added.
772 * regex match: Match values by their identifies using regular
773 expressions.
774 * timediff match: Match for values with an invalid timestamp.
775 * value match: Select values by their data sources' values.
776 * notification target: Create and dispatch a notification.
777 * replace target: Replace parts of an identifier using regular
778 expressions.
779 * set target: Set (overwrite) entire parts of an identifier.
780 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
781 statistics, allowing very detailed name server statistics. Thanks to
782 Bruno Prémont for this plugin.
783 * cpu plugin: Report `interrupt' separately when using
784 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
785 example for native OpenBSD support, has been added. Thanks to Simon
786 Kuhnle for the patch.
787 * csv plugin: Make it possible to write values to STDOUT instead of
788 files. This is meant for testing purposes mostly. The output written
789 to STDOUT is compatible with the exec plugin. Thanks to Doug
790 MacEachern for the patch.
791 * curl plugin: This new plugin can be used to read web pages and parse
792 them using the same mechanism that's used in the tail plugin.
793 * dbi plugin: This new plugin allows you to connect to a variety of
794 relational databases and use SQL to gather custom statistics from
795 it. It is similar to the already existing PostgreSQL plugin but uses
796 libdbi to communicate with the database(s).
797 * interface plugin: Use the ignorelist framework when selecting /
798 ignoring interfaces. This allows one to use regular expressions to
799 select interfaces, too.
800 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
801 Thanks to Bruno Prémont for this patch.
802 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
803 for the patch.
804 * mysql plugin: Allow connecting to a database via the UNIX domain
805 socket, too. Thanks to Mirko Buffoni for the patch.
806 * network plugin: Further performance improvements for the receive
807 code. This hopefully will help very large setups.
808 * openvpn plugin: This new plugin collects statistics provided by the
809 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
810 * oracle plugin: This new plugin allows you to connect to an Oracle
811 database and use SQL to gather custom statistics from it. It is
812 similar to the already existing PostgreSQL plugin.
813 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
814 have been added.
815 * perl plugin: Export the newly added plugin_write() to Perl plugins.
816 * perl plugin: Added support for `notification meta data'.
817 * perl plugin: Added support for the `filter chain' infrastructure by
818 allowing plugins to register `matches' and `targets'.
819 * postgresql plugin: The preferred configuration syntax has been
820 updated to be in line with the syntax used by the new dbi and oracle
821 plugins. The compatibility code for the old syntax is present.
822 Support for the new `Result' blocks and the interval parameter has
823 been added.
824 * processes plugin: Stacksize and virtual memory usage statistics have
825 been added. Portability fixes.
826 * rrdcached plugin: This new plugin uses the (still in development)
827 RRD accelerator daemon, rrdcached. This daemon works very similar to
828 the original rrdtool plugin of collectd, but adds some more nice
829 features.
830 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
831 added.
833 2009-05-09, Version 4.5.4
834 * Build system, various plugins: Many build fixes for FreeBSD,
835 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
836 for many fixes and providing a build system for many platforms,
837 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
838 providing an OpenBSD system.
839 * collectd: Fix a potential race condition when creating directories.
840 * battery plugin: Don't complain about a missing directory every
841 interval.
842 * dns plugin: Slight portability fixes.
843 * exec plugin: Allow executed programs to close STDERR. Thanks to
844 Thorsten von Eicken for reporting this problem.
845 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
846 Tomasz Pala for the patch.
847 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
848 the patch.
849 * rrdtool plugin: Fix a possible race condition: If the network plugin
850 is initialized and dispatches a value before the rrdtool plugin is
851 initialized, the daemon may crash.
852 * memory plugin: Fix a potential problem under Solaris.
854 2009-02-22, Version 4.5.3
855 * build system: The check for libupsclient even when `pkg-config' is
856 not available.
857 * collectd: Fix error handling in the global cache.
858 * Collectd::Unixsock: Error handling has been improved.
859 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
860 patch.
861 * ipmi plugin: Fix an off-by-one error which could cause segmentation
862 faults. Thanks to Peter Holik for his patch.
863 * tcpconns plugin: An endianness problem has been fixed in the *BSD
864 code. Thanks to "thated" for reporting this.
866 2009-01-02, Version 4.5.2
867 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
868 file may be in both locations, especially when the database was
869 installed in a non-standard path. Thanks to Dusty Doris for
870 reporting this.
871 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
872 Solaris, in the configure script automatically.
873 * build system, tcpconns plugin: Check for `kvm_nlist' and
874 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
875 library with similar functions to the BSD variant, but doesn't
876 provide these necessary functions.
877 * collectd.conf(5): Various fixes and clarifications.
878 * collectd: Remove a GNUism (unnamed unions), thus improving
879 portability.
880 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
881 This solves portability problems, especially for Solaris.
882 * dns plugin: Fix a portability problem with NetBSD.
883 * filecount plugin: Fix an off-by-one error. This error may cause a
884 segmentation fault.
885 * network plugin: Fix the handling of `type' in the network protocol.
886 Due to a programming mistake, only 4 or 8 bytes would be copied to a
887 much larger buffer. This caused the `type' to be transferred much
888 more often than necessary. In some cases, e. g. the `cpu' and
889 `cpufreq' plugins being used at the same time, data may be corrupted
890 in those files. Thanks to Bruno Prémont for debugging and reporting
891 this issue.
892 * processes plugin: Fix a possible segmentation fault when specifying
893 invalid configuration options.
894 * unixsock plugin: Make sure the initialization function is run only
895 once. This resolves a file descriptor leak under systems which run
896 the initialization more than once, such as Solaris.
898 2008-10-16, Version 4.5.1
899 * build system: Change `--enable-<plugin>' to abort with an error if
900 dependencies are not met. Thanks to Bruno Prémont for the patch.
901 Also, the poisoning of various string functions has been restricted
902 to debug builds.
903 * collectd: Fix a memory leak in the global value cache. With every
904 *missing* value a couple of bytes would be leaked. Another memory
905 leak in the configuration handling code has been fixed. Thanks to
906 Niraj Tolia for reporting these issues.
907 * collectd: Fix an off-by-one error in the ignorelist functionality.
908 When using regular expressions, the last character would be missing,
909 possibly matching differently from what one would expect.
910 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
911 problem.
912 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
913 Linzberger for reporting the bug.
914 * iptables plugin: Fix an off-by-one error. If a string was just one
915 character too long, it was truncated instead of reporting an error.
916 * network plugin: Fix a memory leak in the configuration handling
917 code. Thanks to Niraj Tolia for reporting this issue.
918 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
919 * postgresql plugin: Don't reopen connection during reinitialization.
920 This fixes a bug under Solaris and potentially other platforms.
921 Missing calls to `PQclear' have been added, too. This fixes memory
922 leaks. Thanks to ``Admin'' for reporting these bugs.
923 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
924 library.
925 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
926 problems with some `libc's. Thanks to Matthias Lay for reporting the
927 bug.
929 2008-09-04, Version 4.5.0
930 * collectd: Added the ability to flush certain identifiers.
931 * collectd: The concept of `notification meta data' has been
932 introduced.
933 * filecount plugin: The new filecount plugin counts the number of
934 files in a directory and its subdirectories.
935 * ipmi plugin: Sensor names have been changed to ensure unique names.
936 Notifications upon added and removed sensors can now be generated.
937 * notify_desktop plugin: This new plugin sends notifications to the
938 X desktop using the structure defined in the `Desktop Notification
939 Specification'.
940 * notify_email plugin: This new plugin sends out notifications via
941 email, using the `esmtp' library.
942 * onewire plugin: The new experimental(!) onewire plugin reads values,
943 such as temperatures, from sensors connected to the computer via the
944 onewire bus.
945 * perl plugin: Improved synchronized access to internal data structures
946 and fixed a possible dead-lock.
947 * perl plugin: Added the ability to flush certain identifiers and marked
948 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
949 plugin_flush().
950 * perl plugin: Added the ability to configure Perl plugins.
951 * postgresql plugin: The new postgresql plugin collects statistics
952 about or from a PostgreSQL database.
953 * processes plugin: The `ProcessMatch' option has been added.
954 * rrdtool plugin: Implement throttling of the `update queue' to lessen
955 IO load.
956 * tcpconns plugin: This plugin has been ported to OpenBSD.
957 * thermal plugin: The new thermal plugin collects system temperatures
958 using Linux ACPI thermal zone data.
960 2009-01-02, Version 4.4.5
961 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
962 file may be in both locations, especially when the database was
963 installed in a non-standard path. Thanks to Dusty Doris for
964 reporting this.
965 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
966 Solaris, in the configure script automatically.
967 * collectd.conf(5): Various fixes and clarifications.
968 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
969 portability problems, especially for Solaris.
970 * dns plugin: Fix a portability problem with NetBSD.
971 * network plugin: Fix the handling of `type' in the network protocol.
972 Due to a programming mistake, only 4 or 8 bytes would be copied to a
973 much larger buffer. This caused the `type' to be transferred much
974 more often than necessary. In some cases, e. g. the `cpu' and
975 `cpufreq' plugins being used at the same time, data may be corrupted
976 in those files. Thanks to Bruno Prémont for debugging and reporting
977 this issue.
978 * unixsock plugin: Make sure the initialization function is run only
979 once. This resolves a file descriptor leak under systems which run
980 the initialization more than once, such as Solaris.
982 2008-10-16, Version 4.4.4
983 * build system: Change `--enable-<plugin>' to abort with an error if
984 dependencies are not met. Thanks to Bruno Prémont for the patch.
985 Also, the poisoning of various string functions has been restricted
986 to debug builds.
987 * collectd: Fix a memory leak in the global value cache. With every
988 *missing* value a couple of bytes would be leaked. Another memory
989 leak in the configuration handling code has been fixed. Thanks to
990 Niraj Tolia for reporting these issues.
991 * collectd: Fix an off-by-one error in the ignorelist functionality.
992 When using regular expressions, the last character would be missing,
993 possibly matching differently from what one would expect.
994 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
995 problem.
996 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
997 Linzberger for reporting the bug.
998 * network plugin: Fix a memory leak in the configuration handling
999 code. Thanks to Niraj Tolia for reporting this issue.
1000 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1001 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1002 problems with some `libc's. Thanks to Matthias Lay for reporting the
1003 bug.
1005 2008-09-01, Version 4.4.3
1006 * collectd: Fix a memory leak in the threshold checking code.
1007 * memcached plugin: Fix a too short timeout and a related file
1008 descriptor leak.
1009 * memory plugin: A typo in the libstatgrab code has been fixed.
1010 * snmp plugin: Fix a possible memory leak.
1012 2008-07-15, Version 4.4.2
1013 * build system: Use pkg-config to detect the upsclient library.
1014 * collectd: Try even harder to determine the endianess of the
1015 architecture collectd is being built on.
1016 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1017 of disks.
1018 * dns plugin: Fix compilation errors with BIND versions 19991001
1019 through 19991005.
1020 * network plugin: Bugfix in the init routine: The init function
1021 cleared a buffer regardless of its contents. This could lead to lost
1022 values under Solaris.
1023 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1024 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1025 function.
1026 * wireless plugin: Work around incorrect noise and power values
1027 returned by some broken drivers.
1029 2008-06-03, Version 4.4.1
1030 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1031 to kyrone for reporting this.
1032 * collectd: Fixed min/max output in notifications generated by
1033 threshold checking.
1034 * collectd-nagios: Fix the protocol used to communicate with the
1035 daemon.
1036 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1037 initialization has errors. An issue with Perl 5.10 has been fixed.
1038 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1039 René Rebe and Siegmund Gorr for reporting this.
1041 2008-05-06, Version 4.4.0
1042 * collectd: Internal code cleanups.
1043 * collectd: Added support for a `Flush' command in the unixsock and
1044 exec plugins. This command can be used to force a plugin (or all) to
1045 flush its values to disk.
1046 * collectd: Thresholds can now be configured to apply to one data
1047 source only, making it possible to configure different thresholds
1048 for each data source.
1049 * apache, nginx plugins: Added the possibility to disable host and/or
1050 peer verification.
1051 * ascent plugin: The new ascent plugin reads and parses the statistics
1052 page of an Ascent server.
1053 * cpu plugin: Support for the statgrab library has been added.
1054 * disk plugin: The possibility to ignore certain disks or collect only
1055 specific disks has been added.
1056 * disk plugin: Support for the statgrab library has been added.
1057 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1058 sensor values via IPMI, the intelligent platform management
1059 interface.
1060 * iptables plugin: The iptc library that is used by the iptables
1061 plugin has been added to the distribution, because it is not
1062 provided by all distributions and removed from at least one.
1063 * powerdns plugin: The new powerdns plugin reads statistics from an
1064 authoritative or a recursing PowerDNS name server.
1065 * rrdtool plugin: The size of the files generated with the default
1066 configuration has been decreased.
1067 * tail plugin: The new tail plugin can be used to gather statistics by
1068 continuously reading from log files.
1069 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1070 TeamSpeak2 server and collects statistics about the number of users
1071 and number of channels.
1072 * users plugin: Support for the statgrab library has been added.
1073 * vmem plugin: The new vmem plugin collects very detailed statistics
1074 about the virtual memory subsystem of Linux.
1076 2008-08-30, Version 4.3.4
1077 * Build system: Improved detection of and linking with the statgrab
1078 library.
1079 * collectd: Portability fixes, especially to determine endianess more
1080 reliable.
1081 * Various plugins: Fix format strings.
1082 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1083 again has been applied.
1084 * memcached plugin: Fix a too short timeout and a related file
1085 descriptor leak.
1086 * memory plugin: A typo in the libstatgrab code has been fixed.
1087 * network plugin: A fix in the initialization function solves problems
1088 under Solaris.
1089 * nginx plugin: A thread-unsafe function has been replaced.
1090 * vserver plugin: A thread-unsafe function has been replaced.
1091 * wireless plugin: A work-around for broken wireless drivers has been
1092 added.
1094 2008-04-22, Version 4.3.3
1095 * build system: Improved detection of several libraries, especially if
1096 they are in non-standard paths.
1097 * build system: Portability fixes: Automatically define "_REENTRANT"
1098 if the libc expects it.
1099 * collectd: Error and warning messages have been improved.
1100 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1101 using them.
1102 * apache plugin: Allocate new memory when reading a webpage instead of
1103 using a buffer of static size.
1104 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1105 the program.
1106 * hddtemp plugin: Error and warning messages have been improved.
1107 * sensors plugin: Fix sensor collection for some chip types.
1109 2008-03-29, Version 4.3.2
1110 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1111 `Persist' threshold options.
1112 * collectd: Fix handling of missing values in the global value cache.
1113 * collectd: Improved error messages when parsing the configuration.
1114 * sensors plugin: Fix temperature collection with libsensors4.
1115 * unixsock plugin: Fix mixed input and output operation on streams.
1116 * wireless plugin: Fix reading noise value.
1118 2008-03-05, Version 4.3.1
1119 * exec plugin: Set supplementary group IDs.
1120 * network plugin:
1121 + Use `memcpy' when constructing/parsing a package to avoid
1122 alignment problems on weird architectures, such as Sparc.
1123 + Translate doubles to/from the x86 byte representation to ensure
1124 cross-platform compatibility.
1125 * ping plugin: Correct the handling of the `TTL' setting.
1126 * swap plugin: Reapply a patch for Solaris.
1127 * tcpconns plugin: Portability improvements.
1129 2008-02-18, Version 4.3.0
1130 * collectd: Notifications have been added to the daemon. Notifications
1131 are status messages that may be associated with a data instance.
1132 * collectd: Threshold checking has been added to the daemon. This
1133 means that you can configure threshold values for each data
1134 instance. If this threshold is exceeded a notification will be
1135 created.
1136 * collectd: The new `FQDNLookup' option tells the daemon to use the
1137 full qualified domain name as the hostname, not just the host part
1138 es returned by `gethostname(2)'.
1139 * collectd: Support for more than one `TypesDB' file has been added.
1140 This is useful when one such file is included in a package but one
1141 wants to add custom type definitions.
1142 * collectd: The `Include' config option has been expanded to handle
1143 entire directories and shell wildcards.
1144 * collectdmon: The new `collectdmon' binary detects when collectd
1145 terminates and automatically restarts it again.
1146 * csv plugin: The CSV plugin is now able to store counter values as a
1147 rate, using the `StoreRates' configuration option.
1148 * exec plugin: Handling of notifications has been added and the
1149 ability to pass arguments to the executed programs has been added.
1150 * hddtemp plugin: The new `TranslateDevicename' option lets you
1151 disable the translation from device names to major-minor-numbers.
1152 * logfile plugin: Handling of notifications has been added.
1153 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1154 domain name lookups in this plugin.
1155 * perl plugin: Many internal changes added support for handling multiple
1156 threads making the plugin reasonably usable inside collectd. The API has
1157 been extended to support notifications and export global variables to
1158 Perl plugins; callbacks now have to be identified by name rather than a
1159 pointer to a subroutine. The plugin is no longer experimental.
1160 * uuid plugin: The new UUID plugin sets the hostname to an unique
1161 identifier for this host. This is meant for setups where each client
1162 may migrate to another physical host, possibly going through one or
1163 more name changes in the process. Thanks to Richard Jones from
1164 Red Hat's Emerging Technology group for this plugin.
1165 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1166 CPU, disk and network statistics about guest systems on the same
1167 physical server. Thanks to Richard Jones from Red Hat's Emerging
1168 Technology group for this plugin.
1170 2008-04-22, Version 4.2.7
1171 * build system: Improved detection of several libraries, especially if
1172 they are in non-standard paths.
1173 * build system: Portability fixes: Automatically define "_REENTRANT"
1174 if the libc expects it.
1175 * collectd: Error and warning messages have been improved.
1176 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1177 using them.
1178 * apache plugin: Allocate new memory when reading a webpage instead of
1179 using a buffer of static size.
1180 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1181 the program.
1182 * hddtemp plugin: Error and warning messages have been improved.
1183 * sensors plugin: Fix sensor collection for some chip types.
1185 2008-03-29, Version 4.2.6
1186 * collectd: Improved error messages when parsing the configuration.
1187 * sensors plugin: Fix temperature collection with libsensors4.
1188 * unixsock plugin: Fix mixed input and output operation on streams.
1189 * wireless plugin: Fix reading noise value.
1191 2008-03-04, Version 4.2.5
1192 * apache plugin: Improved initialization and error messages.
1193 * exec plugin: Set supplementary group IDs.
1194 * network plugin:
1195 + Create separate threads for reading from the socket and parsing
1196 and dispatching incoming packets. Versions prior to this may have
1197 problems in high-load situations, where the socket receive buffers
1198 overflows, resulting in gaps in the data.
1199 + Use `memcpy' when constructing/parsing a package to avoid
1200 alignment problems on weird architectures, such as Sparc.
1201 + Translate doubles to/from the x86 byte representation to ensure
1202 cross-platform compatibility.
1203 * ping plugin: Correct the handling of the `TTL' setting.
1204 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1205 * swap plugin: Reapply a patch for Solaris.
1206 * tcpconns plugin: Portability improvements.
1208 2008-01-21, Version 4.2.4
1209 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1210 the permission on the socket as documented in the manpage. Thanks to
1211 Evgeny Chukreev for fixing this issue.
1212 * collectd: The documentation has been improved.
1214 2007-12-28, Version 4.2.3
1215 * sensors plugin: Updated the plugin to build and work with version 3
1216 of the libsensors library.
1218 2007-12-15, Version 4.2.2
1219 * nginx plugin: Incorrect comparison of strings lead to a segfault
1220 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1221 this.
1222 * logfile plugin: The config option `Timestamp' was handled
1223 incorrectly and basically always active. Thanks to Luke Heberling
1224 for fixing this.
1226 2007-11-08, Version 4.2.1
1227 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1228 enabled on the host.
1229 * snmp plugin: Fix a memory leak.
1231 2007-10-27, Version 4.2.0
1232 * collectd: The new config option `Include' lets you include other
1233 configfiles and thus split up your config into smaller parts. This
1234 may be especially interesting for the snmp plugin to keep the data
1235 definitions separate from the host definitions.
1236 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1237 (number of connections, octets and packets for each service and
1238 destination). Thanks to Sebastian Harl for this plugin.
1239 * memcached plugin: The new `memcached' plugin connects to a memcached
1240 daemon process and collects statistics of this distributed caching
1241 system. Thanks to Antony Dovgal for contributing this plugin.
1242 * nginx plugin: The new `nginx' plugin reads the status page of an
1243 nginx daemon and saves the handled connections and requests.
1244 * perl plugin: Many changes, including the added `EnableDebugger'
1245 config option which lets you debug your Perl plugins more easily.
1246 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1247 be more thread-safe otherwise by locking calls to the library.
1248 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1249 correct the values returned by SNMP-agents. If a <data> block is
1250 defined as `table' the instance is now optional. The sequence number
1251 is used as the type-instance in this case. The new `InstancePrefix'
1252 option allows to add arbitrary prefixes to the type-instance.
1253 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1254 certain TCP connections and what state they're in. This can be used
1255 to see how many connections your FTP server has to handle or how
1256 many outgoing connections your mailserver has open.
1258 2008-01-11, Version 4.1.6
1259 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1260 the permission on the socket as documented in the manpage. Thanks to
1261 Evgeny Chukreev for fixing this issue.
1262 * collectd: The documentation has been improved.
1264 2007-12-27, Version 4.1.5
1265 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1266 memory situations.
1267 * sensors plugin: Updated the plugin to build and work with version 3
1268 of the libsensors library.
1270 2007-11-08, Version 4.1.4
1271 * Build system: Improve detection of the rrd library, especially if
1272 it's in a non-standard location.
1273 * Build system: A bug when parsing the argument for
1274 `--with-libnetsnmp' has been fixed.
1275 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1276 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1277 a deadlock or delay when shutting down the daemon.
1278 * snmp plugin: Fix a memory leak.
1280 2007-10-24, Version 4.1.3
1281 * collectd: A build issue under Solaris has been resolved by renaming
1282 data types.
1283 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1284 be more thread-safe otherwise by locking calls to the library.
1286 2007-09-28, Version 4.1.2
1287 * apcups plugin: Fix reporting of the `load percent' data.
1288 * wireless plugin: Correct the handling of cards returning signal and
1289 noise quality as percentage.
1290 * perl plugin: Fix a possible buffer overflow in get_module_name().
1291 * build system: Further improve the detection of libraries.
1292 * netlink plugin: Build issues under some older versions of the Linux
1293 includes (i. e. Debian Sarge) have been fixed.
1294 * snmp plugin: Fix a potential segfault when a host times out. Add
1295 support for the `timeticks' type.
1297 2007-09-12, Version 4.1.1
1298 * Build system: The detection of `libnetlink' has been improved.
1299 * collectd: The documentation has been fixed in numerous places.
1300 * exec plugin: Setting the group under which to run a program has been
1301 fixed.
1302 * collectd: The `sstrerror' function was improved to work correctly
1303 with the broken GNU version of `strerror_r'.
1304 * collectd: Write an error message to STDERR when loading of a plugin
1305 fails.
1306 * apcups plugin: Fix the `types' used to submit the values: They still
1307 has an `apcups_' prefix which doesn't work anymore.
1308 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1309 whatever the client thinks is `now'..
1311 2007-09-01, Version 4.1.0
1312 * Build system: The build system has been changed to automatically
1313 disable all plugins, which are missing dependencies. The dependency
1314 checking has been removed from the plugins themselves to remove
1315 redundancy.
1316 * Flexible interval: The interval of collected data is now sent along
1317 with the data itself over the network, so that the interval-settings
1318 of server and clients no longer needs to match.
1319 * netlink plugin: The new `netlink' plugin connects to the Linux
1320 kernel using a netlink socket and uses it to query information about
1321 interfaces, qdiscs and classes.
1322 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1323 to not block data collection.
1324 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1325 network devices, such as switches, routers, thermometers, rack
1326 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1327 plugin.
1328 * unixsock plugin: Added the `LISTVAL' command.
1329 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1330 of music played with xmms.
1332 2007-09-28, Version 4.0.9
1333 * apcups plugin: Fix reporting of the `load percent' data.
1334 * wireless plugin: Correct the handling of cards returning signal and
1335 noise quality as percentage.
1336 * perl plugin: Fix a possible buffer overflow in get_module_name().
1338 2007-09-12, Version 4.0.8
1339 * collectd: The `sstrerror' function was improved to work correctly
1340 with the broken GNU version of `strerror_r'.
1341 * collectd: Write an error message to STDERR when loading of a plugin
1342 fails.
1343 * apcups plugin: Fix the `types' used to submit the values: They still
1344 has an `apcups_' prefix which doesn't work anymore.
1345 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1346 whatever the client thinks is `now'..
1348 2007-08-26, Version 4.0.7
1349 * documentation: Some typos have been fixed and some information has
1350 been improved.
1351 * build system: Many fixes for detecting libraries in unusual places,
1352 such as on RedHat systems. The affected libraries are `libcurl',
1353 `libmysql', and `libupsclient'.
1354 * network plugin: Allow the `Port' option to be specified as a number
1355 (i. e. without quotes).
1356 * nut plugin: A fix allows linking the nut plugin against
1357 libupsclient, version >= 2.2.0.
1358 * processes plugin: Fix a potential segmentation fault.
1360 2007-07-30, Version 4.0.6
1361 * sensors plugin: Fix the ignorelist functionality: Only the `type
1362 instance' was used to match against the list, but the documentation
1363 told otherwise. This release fixes the code, so it complies with the
1364 documentation.
1365 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1366 configuration messages will end up in the logging facility.
1367 * conrtib/fedora: The contributed specfile for Fedora has been
1368 updated.
1370 2007-07-05, Version 4.0.5
1371 * Portability: More fixes for OpenBSD have been included.
1373 2007-06-24, Version 4.0.4
1374 * cpu plugin: Fixed the Solaris code.

1376 * interface plugin: Fixed the Solaris code.
1377 * load plugin: Fixed the alternative `/proc' Linux code.
1378 * memory plugin: Fixed the Solaris code.
1379 * oconfig: Don't require `-lfl' anymore.
1381 2007-06-19, Version 4.0.3
1382 * cpu plugin: Fix the Darwin / Mac OS X code.
1383 * ping plugin: Use the return value of `getpid', not its address.
1384 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1385 initialized correctly.
1386 * configure: Added `--with-nan-emulation' to aid cross compilation.
1388 2007-06-12, Version 4.0.2
1389 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1390 they're given in numerically form.
1392 2007-06-07, Version 4.0.1
1393 * iptables plugin: A bug in the configuration routine has been fixed.
1394 Setting a comment in the configfile will no longer cause a
1395 segmentation fault.
1397 2007-06-03, Version 4.0.0
1398 * collectd: The plugin-infrastructure has been changed to allow for
1399 more types of plugins, namely `write' and `log' plugins.
1400 * collectd: The read-function has been changed to read many plugins in
1401 parallel, using threads. Thus, plugins generally need to use
1402 thread-safe functions from now on.
1403 * collectd: The '-t' command line options allows to perform syntax tests
1404 of the configuration file and exit immediately.
1405 * csv plugin: The new `csv' plugin handles output to `comma separated
1406 values'-files.
1407 * rrdtool plugin: The new `rrdtool' plugin handles output to
1408 RRD-files. Data can be cached to combine multiple updates into one
1409 write to increase IO-performance.
1410 * network plugin: The new `network' plugin handles IO via the network.
1411 It implements a different, much more extensible protocol which can
1412 combine many values in one packet, decreasing the number of UDP-
1413 packets being sent. It can read from and send to the network and
1414 with the appropriate configuration even forward packets to other
1415 networks.
1416 * unixsock plugin: The new `unixsock' plugin provides an interface to
1417 communicate with the daemon while it is running. Right now the
1418 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1419 come.
1420 * perl plugin: The new `perl' plugin allows you to write extensions
1421 for collectd in the scripting-language Perl.
1422 * logfile plugin: The new `logfile' plugin writes logmessages to files
1423 or STDOUT or STDERR.
1424 * syslog plugin: The new `syslog' plugin sends logmessages to the
1425 system's syslog daemon.
1426 * entropy plugin: The new `entropy' plugin collects the amount of
1427 entropy currently being available to the system.
1428 * exec plugin: The new `exec' plugin forks child processes and reads
1429 back values provided by the forked processes.
1430 * iptables plugin: The new `iptables' plugin reads counters from
1431 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1432 plugin.
1433 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1434 to Peter Holik for contributing this plugin.
1435 * nut plugin: The new `nut' plugin connects the upsd of the `network
1436 ups tools' and reads information about the connected UPS.
1437 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1438 connections) field was added by Florent Monbillard.
1439 * collectd-nagios: The new `collectd-nagios' binary queries values
1440 from collectd, parses them and exits according to Nagios-standards.
1441 * manpages: The manpages have been improved a lot.
1443 2007-09-28, Version 3.11.7
1444 * wireless plugin: Correct the handling of cards returning signal and
1445 noise quality as percentage.
1447 2007-08-31, Version 3.11.6
1448 * processes plugin: Fix a potential segmentation fault.
1450 2007-05-29, Version 3.11.5
1451 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1452 * ntpd plugin: Fix a potential buffer overflow.
1453 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1454 were accounted as `zombies'.
1456 2007-04-10, Version 3.11.4
1457 * dns plugin: Change the order of includes to make the plugin compile
1458 under FreeBSD.
1460 2007-03-30, Version 3.11.3
1461 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1462 of the unused `COLLECT_KSTAT'.
1464 2007-02-11, Version 3.11.2
1465 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1466 NULL-pointer may have been passed to `printf' which causes a
1467 segfault with some libcs.
1469 2007-02-10, Version 3.11.1
1470 * df plugin: Some wrong defines have been fixed so the plugin works
1471 under Solaris again.
1472 * dns plugin: The usage of a struct has been fixed to work with
1473 non-GNU libcs.
1474 * processes plugin: Some missing defines have been added so the plugin
1475 compiles cleanly under FreeBSD and presumably other UNIXes.
1477 2006-12-22, Version 3.11.0
1478 * collectd: The new command line option `-P' makes it easier for
1479 distributors to change the location of PID-files.
1480 * collectd: The daemon shuts down faster now which makes it easier to
1481 write init.d-scripts for it.
1482 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1483 caused problems every now and then.
1484 * df plugin: New config options allow to ignore certain mountpoints,
1485 filesystem types or devices.
1486 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1487 and interprets it. It collects traffic as well as qtype, opcode and
1488 rcode counts.
1489 * email plugin: Sebastian Harl has contributed this plugin which
1490 counts received mails in categories (e. g. ham, spam, virus), spam
1491 score (as given by SpamAssassin) and check types.
1492 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1493 uses `mbmon' to gather information from sensors on the motherboard.
1494 * processes plugin: Collect detailed statistics for configured
1495 processes, that's process and thread count, CPU usage, resident
1496 segment size and pagefaults.
1497 * multimeter plugin: Peter Holik contributed a new plugin which
1498 queries multimeters.
1499 * sensors plugin: Lubos Stanek has put much effort into improving this
1500 plugin, including `extended naming', collection of voltage values
1501 and the possibility to ignore certain values.
1503 2006-12-21, Version 3.10.4
1504 * Max Kellermann has identified a bug in the server routine: When
1505 opening a socket fails the daemon will (re)try opening the socket in
1506 an endless loop, ultimately leading to a `EMFILE' error.
1508 2006-11-04, Version 3.10.3
1509 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1510 ntpd's reply was sent in more than one packet, the buffer size was
1511 calculated incorrectly, resulting in the reading of uninitialized or
1512 freed memory.
1514 2006-11-01, Version 3.10.2
1515 * The sample config file has been improved.
1516 * Errors in the manpages have been corrected.
1517 * The ping-plugin now adds hosts during initialization, not during
1518 startup. This speeds up startup when no network connectivity is
1519 available. Also, the hosts are being added later when the network is
1520 available.
1521 * Improved BSD-support for the df-plugin.
1522 * Fixed syntax errors in the swap-plugin for Mac OS X.
1523 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1524 plugin.
1525 * Don't disable the mysql-plugin if connecting to the database fails
1526 during initialization. Instead, try again in increasing intervals.
1528 2006-07-19, Version 3.10.1
1529 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1530 the apcups cannot be reached, unconnected sockets will pile up and
1531 eventually lead to `Too many open files' errors.
1533 2006-07-09, Version 3.10.0
1534 * The `disk' plugin has been ported to Darwin.
1535 * The `battery' plugin should work on many Apple computers now.
1536 * The `traffic' plugin can now ignore certain interfaces. Also,
1537 statistics for sent/received packets and errors have been added.
1538 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1539 to Anthony Gialluca for contributing this plugin and providing me
1540 with a test environment :)
1541 * A plugin for monitoring an NTP instance and the local clock drift
1542 has been added.
1544 2006-06-25, Version 3.9.4
1545 * The Solaris code in the `swap' plugin has been changed to reflect
1546 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1547 working this out.
1548 * The debugging system has been fixed to work with the Sun libc.
1549 * When built without librrd the variable `operating_mode' could be
1550 uninitialized. Thanks to David Elliot for reporting the bug.
1552 2006-06-01, Version 3.9.3
1553 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1554 operating systems also profit from the changes, but I wasn't able to
1555 check that.
1556 * Changed the build system to find the netinet-includes under FreeBSD
1557 and therefore successfully build the `liboping' library there.
1559 2006-05-09, Version 3.9.2
1560 * Applied a patch to the `liboping' library. Due to a bug in the
1561 sequence checking the `ping' plugin stopped working after
1562 approximately 7.6 days.
1564 2006-05-09, Version 3.8.5
1565 * Applied a patch to the `liboping' library. Due to a bug in the
1566 sequence checking the `ping' plugin stopped working after
1567 approximately 7.6 days.
1569 2006-04-21, Version 3.9.1
1570 * Build issues with Solaris and possible other architectures have been
1571 resolved.
1572 * Problems when building the `apache'-plugin without `libcurl' have
1573 been resolved.
1574 * A bug in the `ping' plugin has been fixed. Sorry folks.
1576 2006-04-02, Version 3.9.0
1577 * A plugin to monitor the Apache webserver has been added.
1578 <http://httpd.apache.org/>
1579 * A plugin to collect statistics about virtual servers using VServer.
1580 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1581 this plugin :)
1582 * A plugin for wireless LAN cards has been added. It monitors signal
1583 strength, link quality and noise ratio..
1584 * A plugin for Apple hardware sensors has been added.
1585 * An option to compile collectd with different `step' and `heartbeat'
1586 settings has been added. The size of RRAs is no longer static but
1587 calculated based on the settings for `step' and `width'.
1588 * The `ping' plugin can now be configured to use a certain TTL.
1589 * A plugin to monitor the hardware sensors of Apple computers has been
1590 added.
1591 * The plugins `cpu', `memory', `processes' and `traffic' have been
1592 ported to Mach/Darwin (Mac OS X).
1593 * The `log mode' has been contributed by Christophe Kalt. It writes
1594 the data into text files rather than RRD files.
1596 2006-04-09, Version 3.8.4
1597 * Applied patch by Vincent Stehlé which improves the disk-name
1598 resolution in the `hddtemp' plugin for Linux systems.
1600 2006-04-02, Version 3.8.3
1601 * Applied a patch by James Byers: The MySQL plugin was not working
1602 with MySQL 5.0.2 or later.
1604 2006-03-14, Version 3.8.2
1605 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1606 the GNU libc, because it points to `/etc/fstab' rather than
1607 `/etc/mtab'.
1609 2006-03-13, Version 3.8.1
1610 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1611 * Fixes in the debian `postinst' and `init.d' scripts.
1613 2006-03-09, Version 3.8.0
1614 * The `ping' plugin no longer uses `libping' but a self written
1615 library named `liboping'. With this library it's possible to ping
1616 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1618 2006-02-18, Version 3.7.2
1619 * A simple bug in the `battery' plugin has been fixed. It should now
1620 work with ACPI based batteries as well. Thanks to Sebastian for
1621 fixing this.
1622 * Fixing a bug that prevented collectd to be built without librrd.
1623 Thanks to Werner Heuser for reporting it.
1625 2006-02-04, Version 3.7.1
1626 * The new network code has been improved to build with older versions
1627 of glibc.
1628 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1629 to Tommie Gannert for this patch.
1631 2006-01-30, Version 3.7.0
1632 * The `battery' plugin has been added. It collects information about
1633 laptop batteries..
1634 * The MySQL plugin has been improved: It now writes two more RRD
1635 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1636 * The `cpufreq' plugin now reads another file since the file it did
1637 read so far causes much overhead in the kernel. Also, you need root
1638 to read the old file, but not to read the new one.
1639 * The `hddtemp' plugin can now be configured to connect to another
1640 address and/or port than localhost.
1641 * The `df' plugin now prefers `statvfs' over `statfs'.
1642 * The network code has been rewritten. collectd now supports unicast
1643 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1644 be set in the configfile.
1646 2006-01-24, Version 3.6.2
1647 * Due to a bug in the configfile handling collectd wouldn't start in
1648 client mode. This released fixes this.
1650 2006-01-20, Version 3.6.1
1651 * Due to a bug in `configure.in' all modules and the binary were
1652 linked against `libmysqlclient'. This issue is solved by this
1653 release.
1655 2006-01-17, Version 3.6.0
1656 * A config file has been added. This allows for loading only specific
1657 plugins.
1658 * A `df' plugin has been added.
1659 * A `mysql' plugin has been added.
1660 * The `ping' plugin doesn't entirely give up hope when a socket error
1661 occurred, but will back of and increase the intervals between tries.
1663 2006-01-21, Version 3.5.2
1664 * Fixed yet another bug in the signal handling.. Stupid typo..
1665 * Improved the ping plugin to not give up on socket errors (backport
1666 from 3.6.0).
1668 2005-12-18, Version 3.5.1
1669 * The PID-file is now deleted correctly when shutting down the daemon.
1670 * SIGINT and SIGTERM are now handled correctly.
1672 2005-12-16, Version 3.5.0 (Revision 326)
1673 * A bug in the `load' module under Solaris has been fixed.
1674 * The `users' module has been contributed by Sebastian Harl. It counts
1675 currently logged in users.
1676 * The CPU module now works under FreeBSD without the use of
1677 `libstatgrab', however SMP support is missing.
1678 * The default directories for the RRD files and the PID file now
1679 depend on the compile time setting of `localstatedir'.
1681 2005-11-15, Version 3.4.0 (Revision 236)
1682 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1683 from gentoo's bugzilla for writing the patch.
1684 * The build dependency for librrd has been removed. Binaries built
1685 without librrd are client-only and will multicast their value as
1686 with the `-c' argument.
1687 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1688 * The newly introduced `-f' switch prevents daemon initialization
1689 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1690 Barcellos for this patch.
1692 2005-11-04, Version 3.3.0 (Revision 216)
1693 * New modules have been added:
1694 - `serial', for monitoring traffic on the serial interfaces
1695 - `nfs', for graphing NFS procedure calls
1696 - `tape', traffic from/to tape devices
1697 * The memory.rrd now accepts more than 4Gig of memory.
1699 2005-10-26, Version 3.2.0 (Revision 200)
1700 * Support for graphing the processes has been added (thanks to Lyonel
1701 Vincent)
1702 * If reading from hddtemp fails collectd will increase the time
1703 between polls up to one day.
1704 * The init.d files have been improved.
1705 * Problems with the spec file have been fixed.
1707 2005-10-16, Version 3.1.0 (Revision 194)
1708 * Added the `setsid' syscall to the startup code.
1709 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1711 2005-09-30, Version 3.0.0 (Revision 184)
1712 * The ability to send/receive data to/from the network (think
1713 multicast) has been added.
1714 * Modules have been split up into shared libraries can be loaded at
1715 runtime. The biggest advantage is that the core program doesn't need
1716 to be linked against an external library.
1717 * A patch by George Kargiotakis has been applied: It fixes the sensors
1718 behaviour then more than one sensor is being queried.
1720 2005-09-16, Version 2.1.0 (Revision 172)
1721 * A module for swap statistics has been added.
1723 2005-09-09, Version 2.0.0 (Revision 135)
1724 * Filenames can no longer be configured at program startup. The only
1725 options as of this version are the directory and ping hosts.
1726 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1727 Soft-IRQ statistics are added to `System'.
1728 * Diskstats now collect read and write bytes, not sectors.
1729 * Ping statistics can now be collected for more than one host. There
1730 is no default any more: If no host is given no host will be pinged.
1731 * A self-written patch for libping has been applied so it builds
1732 cleanly.
1734 2005-09-01, Version 1.8.1 (Revision 123)
1735 * Much improved configure-script: libraries and features may now be
1736 disabled.
1737 * More detailed warnings/error messages when RRD update fails.
1739 2005-08-29, Version 1.8.0:
1740 * Support for collecting disk statistics under Solaris.
1742 2005-08-25, Version 1.7.0:
1743 * Support for libstatgrab[1] for load, memory usage and network
1744 traffic. CPU- and disk-usage are not (yet) supported, since
1745 libstatgrab returns insufficient information. I will contact the
1746 authors.
1747 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1748 aren't necessarily counted linear which is now handled correctly.
1749 [1]: http://www.i-scream.org/libstatgrab/
1751 2005-08-21, Version 1.6.0:
1752 * Basic support for Solaris: System load and cpu-usage can be
1753 collected under Solaris, too. Other stats will follow later.
1754 * Many fixes in the autoconf-script
1755 * Collection/Museum scripts have been added under contrib/museum
1756 * collectd may now be started in unprivileged mode, though ping
1757 statistics will not work.
1759 2005-07-17, Version 1.5.1:
1760 * Diskstats-RRDs now use major/minor for naming. Some systems have
1761 weird strings as disk-names..
1763 2005-07-17, Version 1.5:
1764 * A new module, diskstats, has been added. It collects information
1765 about the disks and partitions.
1767 2005-07-11, Version 1.4.2:
1768 * The meminfo module has been changed to work with more platforms
1769 and/or kernel versions.
1771 2005-07-10, Version 1.4.1: Correct traffic stats
1772 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1773 forgot to correct when I changed that module.
1775 2005-07-09, Version 1.4: More traffic stats
1776 * Traffic is now collected for all interfaces that can be found
1777 * Temperature-statistics are read from lm-sensors if available
1779 2005-07-08, Version 1.3: CPU stats
1780 * Collecting CPU statistics now
1782 2005-07-12, Version 1.2: Using syslog
1783 * collectd is now using the syslog facility to report errors, warnings
1784 and the like..
1785 * The default directory is now /var/db/collectd
1787 2005-07-10, Version 1.1: Minor changes
1788 * Nothing really useful to say ;)
1790 2005-07-09, Version 1.0: Initial Version
1791 * The following modules are provided:
1792 * Load average
1793 * Ping time
1794 * Traffic
1795 * Memory info
