472 again.
474 2009-12-18, Version 4.8.2
475 * Build system, java plugin: Don't use “find -L” to search for Java
476 headers, because it's a GNU extension.
477 * Build system: Support for parallel builds has been improved. Thanks
478 Sebastian Harl and Stefan Völkel for looking into this.

549 * empty_counter match: The new Empty Counter match matches value
550 lists, where at least one data source is of type COUNTER and the
551 counter value of all counter data sources is zero.
553 2009-12-18, Version 4.7.5
554 * Build system, java plugin: Don't use “find -L” to search for Java

568 fixed. Thanks to Ben Knight for his patch.
570 2009-10-03, Version 4.7.4
571 * Build system: Issues when building the iptables plugin have been
572 fixed.
573 * exec plugin: Clear the signal block mask before calling exec(2).
574 * perl plugin: Declare the “environ” variable. This solves build

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586 old, no longer valid values when this happens.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

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

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

651 Linux' file-system based caching framework. Thanks to Edward
652 Konetzko for the patch.
653 * gmond plugin: The new gmond plugin can receive and interpret
654 multicast traffic from Ganglia's gmond daemon.
655 * java plugin: The new java plugin exports the collectd API to Java,
656 making it possible to write extensions to collectd in Java.
657 * memcachec plugin: The new memcachec plugin queries data from a
658 memcached daemon and parses it similar to the cURL plugin. Thanks to
659 Doug MacEachern for the initial code.
660 * memcached plugin: Support for connections over UNIX domain sockets
661 has been added. Thanks to Franck Lombardi for the patch.
662 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

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

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

702 to Alan Pevec for the patch.
703 * powerdns plugin: Set a timeout when reading data from the datagram
704 socket. Handling of the “LocalSocket” option has been fixed. An
705 incorrectly used “type” has been corrected. Thanks to Luke Heberling
706 for his patches.

714 for reporting the bug.
716 2009-06-02, Version 4.6.3
717 * Build system, various plugins: Many build fixes for FreeBSD,
718 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
719 for many fixes and providing a build system for many platforms,
720 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
721 providing an OpenBSD system.
722 * collectd: Two bugs with the threshold checking have been fixed. The
723 first one prevented thresholds to be checked at all, the second one
724 caused wrong behavior with the persistency option. Thanks to Andrés
725 J. Díaz for fixing these problems.
726 * collectd: Handling of the `Include' configuration option has been
727 fixed.
728 * battery plugin: Don't complain about a missing directory every
729 interval.

731 Thorsten von Eicken for reporting this problem.
732 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
733 Tomasz Pala for the patch.
734 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
735 the patch.
736 * memory plugin: Fix a potential problem under Solaris.
737 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
738 to Doug MacEachern for the patch.

741 * collectd: Some Solaris utility code has been improved.
742 * filter subsystem: Allow `Chains' without default targets.
743 * liboping: A patch to comply with strict aliasing rules has been
744 added.
745 * timediff match: Fix a typo: The match was registered with a wrong
746 name which prevented this match to be used as documented. Thanks to
747 Bruno Prémont for finding this problem.
748 * bind plugin: Fix collection of the cached RR sets. The number of RR
749 sets currently in the cache was collected as a counter value, which
750 is nonsense. Thanks to Bruno Prémont for implementing this.
751 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
752 primarily BSDs, don't take it well and crash.
753 * oracle plugin: Portability to 64 bit systems has been improved.
754 * postgresql plugin: The default configuration has been improved.
755 * rrdtool plugin: Fix a possible race condition: If the network plugin
756 is brought and dispatches a value before the rrdtool plugin is
757 initialized, the daemon may crash.
759 2009-02-22, Version 4.6.1
760 * collectd: Many documentation fixes.
761 * Collectd::Unixsock: Error handling has been improved.
762 * regex match: Don't link with the PCRE library.
763 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
764 for finding and fixing most of them.
765 * ipmi plugin: Fix an off-by-one error which could cause segmentation
766 faults. Thanks to Peter Holik for his patch.
768 2009-02-16, Version 4.6.0
769 * collectd: Added the `filter chain' infrastructure, which allows the
770 user to use `matches' and `targets' to control value processing.
771 * collectd: The new `-T' command line argument allows more in-depth
772 testing of a configuration. Thanks to Doug MacEachern for the patch.
773 * collectd-nagios: The Nagios integration command has been updated to
774 use libcollectdclient. The `percentage' aggregation function has
775 been added. Thanks to Fabian Linzberger for the patch.
776 * libcollectdclient: A library which abstracts communication with the
777 unixsock plugin for clients has been added.
778 * regex match: Match values by their identifies using regular
779 expressions.
780 * timediff match: Match for values with an invalid timestamp.
781 * value match: Select values by their data sources' values.
782 * notification target: Create and dispatch a notification.
783 * replace target: Replace parts of an identifier using regular
784 expressions.
785 * set target: Set (overwrite) entire parts of an identifier.
786 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
787 statistics, allowing very detailed name server statistics. Thanks to
788 Bruno Prémont for this plugin.
789 * cpu plugin: Report `interrupt' separately when using
790 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
791 example for native OpenBSD support, has been added. Thanks to Simon
792 Kuhnle for the patch.
793 * csv plugin: Make it possible to write values to STDOUT instead of
794 files. This is meant for testing purposes mostly. The output written
795 to STDOUT is compatible with the exec plugin. Thanks to Doug
796 MacEachern for the patch.
797 * curl plugin: This new plugin can be used to read web pages and parse
798 them using the same mechanism that's used in the tail plugin.
799 * dbi plugin: This new plugin allows you to connect to a variety of
800 relational databases and use SQL to gather custom statistics from
801 it. It is similar to the already existing PostgreSQL plugin but uses
802 libdbi to communicate with the database(s).
803 * interface plugin: Use the ignorelist framework when selecting /
804 ignoring interfaces. This allows one to use regular expressions to
805 select interfaces, too.
806 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
807 Thanks to Bruno Prémont for this patch.
808 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
809 for the patch.
810 * mysql plugin: Allow connecting to a database via the UNIX domain
811 socket, too. Thanks to Mirko Buffoni for the patch.
812 * network plugin: Further performance improvements for the receive
813 code. This hopefully will help very large setups.
814 * openvpn plugin: This new plugin collects statistics provided by the
815 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
816 * oracle plugin: This new plugin allows you to connect to an Oracle
817 database and use SQL to gather custom statistics from it. It is
818 similar to the already existing PostgreSQL plugin.
819 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
820 have been added.
821 * perl plugin: Export the newly added plugin_write() to Perl plugins.
822 * perl plugin: Added support for `notification meta data'.
823 * perl plugin: Added support for the `filter chain' infrastructure by
824 allowing plugins to register `matches' and `targets'.
825 * postgresql plugin: The preferred configuration syntax has been
826 updated to be in line with the syntax used by the new dbi and oracle
827 plugins. The compatibility code for the old syntax is present.
828 Support for the new `Result' blocks and the interval parameter has
829 been added.
830 * processes plugin: Stacksize and virtual memory usage statistics have
831 been added. Portability fixes.
832 * rrdcached plugin: This new plugin uses the (still in development)
833 RRD accelerator daemon, rrdcached. This daemon works very similar to
834 the original rrdtool plugin of collectd, but adds some more nice
835 features.
836 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
837 added.
839 2009-05-09, Version 4.5.4
840 * Build system, various plugins: Many build fixes for FreeBSD,
841 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
842 for many fixes and providing a build system for many platforms,
843 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
844 providing an OpenBSD system.
845 * collectd: Fix a potential race condition when creating directories.
846 * battery plugin: Don't complain about a missing directory every
847 interval.
848 * dns plugin: Slight portability fixes.
849 * exec plugin: Allow executed programs to close STDERR. Thanks to
850 Thorsten von Eicken for reporting this problem.
851 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
852 Tomasz Pala for the patch.
853 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
854 the patch.
855 * rrdtool plugin: Fix a possible race condition: If the network plugin
856 is initialized and dispatches a value before the rrdtool plugin is
857 initialized, the daemon may crash.
858 * memory plugin: Fix a potential problem under Solaris.
860 2009-02-22, Version 4.5.3
861 * build system: The check for libupsclient even when `pkg-config' is
862 not available.
863 * collectd: Fix error handling in the global cache.
864 * Collectd::Unixsock: Error handling has been improved.
865 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
866 patch.
867 * ipmi plugin: Fix an off-by-one error which could cause segmentation
868 faults. Thanks to Peter Holik for his patch.
869 * tcpconns plugin: An endianness problem has been fixed in the *BSD
870 code. Thanks to "thated" for reporting this.
872 2009-01-02, Version 4.5.2
873 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
874 file may be in both locations, especially when the database was
875 installed in a non-standard path. Thanks to Dusty Doris for
876 reporting this.
877 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
878 Solaris, in the configure script automatically.
879 * build system, tcpconns plugin: Check for `kvm_nlist' and
880 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
881 library with similar functions to the BSD variant, but doesn't
882 provide these necessary functions.
883 * collectd.conf(5): Various fixes and clarifications.
884 * collectd: Remove a GNUism (unnamed unions), thus improving
885 portability.
886 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
887 This solves portability problems, especially for Solaris.
888 * dns plugin: Fix a portability problem with NetBSD.
889 * filecount plugin: Fix an off-by-one error. This error may cause a
890 segmentation fault.
891 * network plugin: Fix the handling of `type' in the network protocol.
892 Due to a programming mistake, only 4 or 8 bytes would be copied to a
893 much larger buffer. This caused the `type' to be transferred much
894 more often than necessary. In some cases, e. g. the `cpu' and
895 `cpufreq' plugins being used at the same time, data may be corrupted
896 in those files. Thanks to Bruno Prémont for debugging and reporting
897 this issue.
898 * processes plugin: Fix a possible segmentation fault when specifying
899 invalid configuration options.
900 * unixsock plugin: Make sure the initialization function is run only
901 once. This resolves a file descriptor leak under systems which run
902 the initialization more than once, such as Solaris.
904 2008-10-16, Version 4.5.1
905 * build system: Change `--enable-<plugin>' to abort with an error if
906 dependencies are not met. Thanks to Bruno Prémont for the patch.
907 Also, the poisoning of various string functions has been restricted
908 to debug builds.
909 * collectd: Fix a memory leak in the global value cache. With every
910 *missing* value a couple of bytes would be leaked. Another memory
911 leak in the configuration handling code has been fixed. Thanks to
912 Niraj Tolia for reporting these issues.
913 * collectd: Fix an off-by-one error in the ignorelist functionality.
914 When using regular expressions, the last character would be missing,
915 possibly matching differently from what one would expect.
916 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
917 problem.
918 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
919 Linzberger for reporting the bug.
920 * iptables plugin: Fix an off-by-one error. If a string was just one
921 character too long, it was truncated instead of reporting an error.
922 * network plugin: Fix a memory leak in the configuration handling
923 code. Thanks to Niraj Tolia for reporting this issue.
924 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
925 * postgresql plugin: Don't reopen connection during reinitialization.
926 This fixes a bug under Solaris and potentially other platforms.
927 Missing calls to `PQclear' have been added, too. This fixes memory
928 leaks. Thanks to ``Admin'' for reporting these bugs.
929 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
930 library.
931 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
932 problems with some `libc's. Thanks to Matthias Lay for reporting the
933 bug.
935 2008-09-04, Version 4.5.0
936 * collectd: Added the ability to flush certain identifiers.
937 * collectd: The concept of `notification meta data' has been
938 introduced.
939 * filecount plugin: The new filecount plugin counts the number of
940 files in a directory and its subdirectories.
941 * ipmi plugin: Sensor names have been changed to ensure unique names.
942 Notifications upon added and removed sensors can now be generated.
943 * notify_desktop plugin: This new plugin sends notifications to the
944 X desktop using the structure defined in the `Desktop Notification
945 Specification'.
946 * notify_email plugin: This new plugin sends out notifications via
947 email, using the `esmtp' library.
948 * onewire plugin: The new experimental(!) onewire plugin reads values,
949 such as temperatures, from sensors connected to the computer via the
950 onewire bus.
951 * perl plugin: Improved synchronized access to internal data structures
952 and fixed a possible dead-lock.
953 * perl plugin: Added the ability to flush certain identifiers and marked
954 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
955 plugin_flush().
956 * perl plugin: Added the ability to configure Perl plugins.
957 * postgresql plugin: The new postgresql plugin collects statistics
958 about or from a PostgreSQL database.
959 * processes plugin: The `ProcessMatch' option has been added.
960 * rrdtool plugin: Implement throttling of the `update queue' to lessen
961 IO load.
962 * tcpconns plugin: This plugin has been ported to OpenBSD.
963 * thermal plugin: The new thermal plugin collects system temperatures
964 using Linux ACPI thermal zone data.
966 2009-01-02, Version 4.4.5
967 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
968 file may be in both locations, especially when the database was
969 installed in a non-standard path. Thanks to Dusty Doris for
970 reporting this.
971 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
972 Solaris, in the configure script automatically.
973 * collectd.conf(5): Various fixes and clarifications.
974 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
975 portability problems, especially for Solaris.
976 * dns plugin: Fix a portability problem with NetBSD.
977 * network plugin: Fix the handling of `type' in the network protocol.
978 Due to a programming mistake, only 4 or 8 bytes would be copied to a
979 much larger buffer. This caused the `type' to be transferred much
980 more often than necessary. In some cases, e. g. the `cpu' and
981 `cpufreq' plugins being used at the same time, data may be corrupted
982 in those files. Thanks to Bruno Prémont for debugging and reporting
983 this issue.
984 * unixsock plugin: Make sure the initialization function is run only
985 once. This resolves a file descriptor leak under systems which run
986 the initialization more than once, such as Solaris.
988 2008-10-16, Version 4.4.4
989 * build system: Change `--enable-<plugin>' to abort with an error if
990 dependencies are not met. Thanks to Bruno Prémont for the patch.
991 Also, the poisoning of various string functions has been restricted
992 to debug builds.
993 * collectd: Fix a memory leak in the global value cache. With every
994 *missing* value a couple of bytes would be leaked. Another memory
995 leak in the configuration handling code has been fixed. Thanks to
996 Niraj Tolia for reporting these issues.
997 * collectd: Fix an off-by-one error in the ignorelist functionality.
998 When using regular expressions, the last character would be missing,
999 possibly matching differently from what one would expect.
1000 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1001 problem.
1002 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1003 Linzberger for reporting the bug.
1004 * network plugin: Fix a memory leak in the configuration handling
1005 code. Thanks to Niraj Tolia for reporting this issue.
1006 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1007 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1008 problems with some `libc's. Thanks to Matthias Lay for reporting the
1009 bug.
1011 2008-09-01, Version 4.4.3
1012 * collectd: Fix a memory leak in the threshold checking code.
1013 * memcached plugin: Fix a too short timeout and a related file
1014 descriptor leak.
1015 * memory plugin: A typo in the libstatgrab code has been fixed.
1016 * snmp plugin: Fix a possible memory leak.
1018 2008-07-15, Version 4.4.2
1019 * build system: Use pkg-config to detect the upsclient library.
1020 * collectd: Try even harder to determine the endianess of the
1021 architecture collectd is being built on.
1022 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1023 of disks.
1024 * dns plugin: Fix compilation errors with BIND versions 19991001
1025 through 19991005.
1026 * network plugin: Bugfix in the init routine: The init function
1027 cleared a buffer regardless of its contents. This could lead to lost
1028 values under Solaris.
1029 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1030 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1031 function.
1032 * wireless plugin: Work around incorrect noise and power values
1033 returned by some broken drivers.
1035 2008-06-03, Version 4.4.1
1036 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1037 to kyrone for reporting this.
1038 * collectd: Fixed min/max output in notifications generated by
1039 threshold checking.
1040 * collectd-nagios: Fix the protocol used to communicate with the
1041 daemon.
1042 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1043 initialization has errors. An issue with Perl 5.10 has been fixed.
1044 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1045 René Rebe and Siegmund Gorr for reporting this.
1047 2008-05-06, Version 4.4.0
1048 * collectd: Internal code cleanups.
1049 * collectd: Added support for a `Flush' command in the unixsock and
1050 exec plugins. This command can be used to force a plugin (or all) to
1051 flush its values to disk.
1052 * collectd: Thresholds can now be configured to apply to one data
1053 source only, making it possible to configure different thresholds
1054 for each data source.
1055 * apache, nginx plugins: Added the possibility to disable host and/or
1056 peer verification.
1057 * ascent plugin: The new ascent plugin reads and parses the statistics
1058 page of an Ascent server.
1059 * cpu plugin: Support for the statgrab library has been added.
1060 * disk plugin: The possibility to ignore certain disks or collect only
1061 specific disks has been added.
1062 * disk plugin: Support for the statgrab library has been added.
1063 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1064 sensor values via IPMI, the intelligent platform management
1065 interface.
1066 * iptables plugin: The iptc library that is used by the iptables
1067 plugin has been added to the distribution, because it is not
1068 provided by all distributions and removed from at least one.
1069 * powerdns plugin: The new powerdns plugin reads statistics from an
1070 authoritative or a recursing PowerDNS name server.
1071 * rrdtool plugin: The size of the files generated with the default
1072 configuration has been decreased.
1073 * tail plugin: The new tail plugin can be used to gather statistics by
1074 continuously reading from log files.
1075 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1076 TeamSpeak2 server and collects statistics about the number of users
1077 and number of channels.
1078 * users plugin: Support for the statgrab library has been added.
1079 * vmem plugin: The new vmem plugin collects very detailed statistics
1080 about the virtual memory subsystem of Linux.
1082 2008-08-30, Version 4.3.4
1083 * Build system: Improved detection of and linking with the statgrab
1084 library.
1085 * collectd: Portability fixes, especially to determine endianess more
1086 reliable.
1087 * Various plugins: Fix format strings.
1088 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1089 again has been applied.
1090 * memcached plugin: Fix a too short timeout and a related file
1091 descriptor leak.
1092 * memory plugin: A typo in the libstatgrab code has been fixed.
1093 * network plugin: A fix in the initialization function solves problems
1094 under Solaris.
1095 * nginx plugin: A thread-unsafe function has been replaced.
1096 * vserver plugin: A thread-unsafe function has been replaced.
1097 * wireless plugin: A work-around for broken wireless drivers has been
1098 added.
1100 2008-04-22, Version 4.3.3
1101 * build system: Improved detection of several libraries, especially if
1102 they are in non-standard paths.
1103 * build system: Portability fixes: Automatically define "_REENTRANT"
1104 if the libc expects it.
1105 * collectd: Error and warning messages have been improved.
1106 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1107 using them.
1108 * apache plugin: Allocate new memory when reading a webpage instead of
1109 using a buffer of static size.
1110 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1111 the program.
1112 * hddtemp plugin: Error and warning messages have been improved.
1113 * sensors plugin: Fix sensor collection for some chip types.
1115 2008-03-29, Version 4.3.2
1116 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1117 `Persist' threshold options.
1118 * collectd: Fix handling of missing values in the global value cache.
1119 * collectd: Improved error messages when parsing the configuration.
1120 * sensors plugin: Fix temperature collection with libsensors4.
1121 * unixsock plugin: Fix mixed input and output operation on streams.
1122 * wireless plugin: Fix reading noise value.
1124 2008-03-05, Version 4.3.1
1125 * exec plugin: Set supplementary group IDs.
1126 * network plugin:
1127 + Use `memcpy' when constructing/parsing a package to avoid
1128 alignment problems on weird architectures, such as Sparc.
1129 + Translate doubles to/from the x86 byte representation to ensure
1130 cross-platform compatibility.
1131 * ping plugin: Correct the handling of the `TTL' setting.
1132 * swap plugin: Reapply a patch for Solaris.
1133 * tcpconns plugin: Portability improvements.
1135 2008-02-18, Version 4.3.0
1136 * collectd: Notifications have been added to the daemon. Notifications
1137 are status messages that may be associated with a data instance.
1138 * collectd: Threshold checking has been added to the daemon. This
1139 means that you can configure threshold values for each data
1140 instance. If this threshold is exceeded a notification will be
1141 created.
1142 * collectd: The new `FQDNLookup' option tells the daemon to use the
1143 full qualified domain name as the hostname, not just the host part
1144 es returned by `gethostname(2)'.
1145 * collectd: Support for more than one `TypesDB' file has been added.
1146 This is useful when one such file is included in a package but one
1147 wants to add custom type definitions.
1148 * collectd: The `Include' config option has been expanded to handle
1149 entire directories and shell wildcards.
1150 * collectdmon: The new `collectdmon' binary detects when collectd
1151 terminates and automatically restarts it again.
1152 * csv plugin: The CSV plugin is now able to store counter values as a
1153 rate, using the `StoreRates' configuration option.
1154 * exec plugin: Handling of notifications has been added and the
1155 ability to pass arguments to the executed programs has been added.
1156 * hddtemp plugin: The new `TranslateDevicename' option lets you
1157 disable the translation from device names to major-minor-numbers.
1158 * logfile plugin: Handling of notifications has been added.
1159 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1160 domain name lookups in this plugin.
1161 * perl plugin: Many internal changes added support for handling multiple
1162 threads making the plugin reasonably usable inside collectd. The API has
1163 been extended to support notifications and export global variables to
1164 Perl plugins; callbacks now have to be identified by name rather than a
1165 pointer to a subroutine. The plugin is no longer experimental.
1166 * uuid plugin: The new UUID plugin sets the hostname to an unique
1167 identifier for this host. This is meant for setups where each client
1168 may migrate to another physical host, possibly going through one or
1169 more name changes in the process. Thanks to Richard Jones from
1170 Red Hat's Emerging Technology group for this plugin.
1171 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1172 CPU, disk and network statistics about guest systems on the same
1173 physical server. Thanks to Richard Jones from Red Hat's Emerging
1174 Technology group for this plugin.
1176 2008-04-22, Version 4.2.7
1177 * build system: Improved detection of several libraries, especially if
1178 they are in non-standard paths.
1179 * build system: Portability fixes: Automatically define "_REENTRANT"
1180 if the libc expects it.
1181 * collectd: Error and warning messages have been improved.
1182 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1183 using them.
1184 * apache plugin: Allocate new memory when reading a webpage instead of
1185 using a buffer of static size.
1186 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1187 the program.
1188 * hddtemp plugin: Error and warning messages have been improved.
1189 * sensors plugin: Fix sensor collection for some chip types.
1191 2008-03-29, Version 4.2.6
1192 * collectd: Improved error messages when parsing the configuration.
1193 * sensors plugin: Fix temperature collection with libsensors4.
1194 * unixsock plugin: Fix mixed input and output operation on streams.
1195 * wireless plugin: Fix reading noise value.
1197 2008-03-04, Version 4.2.5
1198 * apache plugin: Improved initialization and error messages.
1199 * exec plugin: Set supplementary group IDs.
1200 * network plugin:
1201 + Create separate threads for reading from the socket and parsing
1202 and dispatching incoming packets. Versions prior to this may have
1203 problems in high-load situations, where the socket receive buffers
1204 overflows, resulting in gaps in the data.
1205 + Use `memcpy' when constructing/parsing a package to avoid
1206 alignment problems on weird architectures, such as Sparc.
1207 + Translate doubles to/from the x86 byte representation to ensure
1208 cross-platform compatibility.
1209 * ping plugin: Correct the handling of the `TTL' setting.
1210 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1211 * swap plugin: Reapply a patch for Solaris.
1212 * tcpconns plugin: Portability improvements.
1214 2008-01-21, Version 4.2.4
1215 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1216 the permission on the socket as documented in the manpage. Thanks to
1217 Evgeny Chukreev for fixing this issue.
1218 * collectd: The documentation has been improved.
1220 2007-12-28, Version 4.2.3
1221 * sensors plugin: Updated the plugin to build and work with version 3
1222 of the libsensors library.
1224 2007-12-15, Version 4.2.2
1225 * nginx plugin: Incorrect comparison of strings lead to a segfault
1226 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1227 this.
1228 * logfile plugin: The config option `Timestamp' was handled
1229 incorrectly and basically always active. Thanks to Luke Heberling
1230 for fixing this.
1232 2007-11-08, Version 4.2.1
1233 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1234 enabled on the host.
1235 * snmp plugin: Fix a memory leak.
1237 2007-10-27, Version 4.2.0
1238 * collectd: The new config option `Include' lets you include other
1239 configfiles and thus split up your config into smaller parts. This
1240 may be especially interesting for the snmp plugin to keep the data
1241 definitions separate from the host definitions.
1242 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1243 (number of connections, octets and packets for each service and
1244 destination). Thanks to Sebastian Harl for this plugin.
1245 * memcached plugin: The new `memcached' plugin connects to a memcached
1246 daemon process and collects statistics of this distributed caching
1247 system. Thanks to Antony Dovgal for contributing this plugin.
1248 * nginx plugin: The new `nginx' plugin reads the status page of an
1249 nginx daemon and saves the handled connections and requests.
1250 * perl plugin: Many changes, including the added `EnableDebugger'
1251 config option which lets you debug your Perl plugins more easily.
1252 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1253 be more thread-safe otherwise by locking calls to the library.
1254 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1255 correct the values returned by SNMP-agents. If a <data> block is
1256 defined as `table' the instance is now optional. The sequence number
1257 is used as the type-instance in this case. The new `InstancePrefix'
1258 option allows to add arbitrary prefixes to the type-instance.
1259 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1260 certain TCP connections and what state they're in. This can be used
1261 to see how many connections your FTP server has to handle or how
1262 many outgoing connections your mailserver has open.
1264 2008-01-11, Version 4.1.6
1265 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1266 the permission on the socket as documented in the manpage. Thanks to
1267 Evgeny Chukreev for fixing this issue.
1268 * collectd: The documentation has been improved.
1270 2007-12-27, Version 4.1.5
1271 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1272 memory situations.
1273 * sensors plugin: Updated the plugin to build and work with version 3
1274 of the libsensors library.
1276 2007-11-08, Version 4.1.4
1277 * Build system: Improve detection of the rrd library, especially if
1278 it's in a non-standard location.
1279 * Build system: A bug when parsing the argument for
1280 `--with-libnetsnmp' has been fixed.
1281 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1282 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1283 a deadlock or delay when shutting down the daemon.
1284 * snmp plugin: Fix a memory leak.
1286 2007-10-24, Version 4.1.3
1287 * collectd: A build issue under Solaris has been resolved by renaming
1288 data types.
1289 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1290 be more thread-safe otherwise by locking calls to the library.
1292 2007-09-28, Version 4.1.2
1293 * apcups plugin: Fix reporting of the `load percent' data.
1294 * wireless plugin: Correct the handling of cards returning signal and
1295 noise quality as percentage.
1296 * perl plugin: Fix a possible buffer overflow in get_module_name().
1297 * build system: Further improve the detection of libraries.
1298 * netlink plugin: Build issues under some older versions of the Linux
1299 includes (i. e. Debian Sarge) have been fixed.
1300 * snmp plugin: Fix a potential segfault when a host times out. Add
1301 support for the `timeticks' type.
1303 2007-09-12, Version 4.1.1
1304 * Build system: The detection of `libnetlink' has been improved.
1305 * collectd: The documentation has been fixed in numerous places.
1306 * exec plugin: Setting the group under which to run a program has been
1307 fixed.
1308 * collectd: The `sstrerror' function was improved to work correctly
1309 with the broken GNU version of `strerror_r'.
1310 * collectd: Write an error message to STDERR when loading of a plugin
1311 fails.
1312 * apcups plugin: Fix the `types' used to submit the values: They still
1313 has an `apcups_' prefix which doesn't work anymore.
1314 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1315 whatever the client thinks is `now'..
1317 2007-09-01, Version 4.1.0
1318 * Build system: The build system has been changed to automatically
1319 disable all plugins, which are missing dependencies. The dependency
1320 checking has been removed from the plugins themselves to remove
1321 redundancy.
1322 * Flexible interval: The interval of collected data is now sent along
1323 with the data itself over the network, so that the interval-settings
1324 of server and clients no longer needs to match.
1325 * netlink plugin: The new `netlink' plugin connects to the Linux
1326 kernel using a netlink socket and uses it to query information about
1327 interfaces, qdiscs and classes.
1328 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1329 to not block data collection.
1330 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1331 network devices, such as switches, routers, thermometers, rack
1332 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1333 plugin.
1334 * unixsock plugin: Added the `LISTVAL' command.
1335 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1336 of music played with xmms.
1338 2007-09-28, Version 4.0.9
1339 * apcups plugin: Fix reporting of the `load percent' data.
1340 * wireless plugin: Correct the handling of cards returning signal and
1341 noise quality as percentage.
1342 * perl plugin: Fix a possible buffer overflow in get_module_name().
1344 2007-09-12, Version 4.0.8
1345 * collectd: The `sstrerror' function was improved to work correctly
1346 with the broken GNU version of `strerror_r'.
1347 * collectd: Write an error message to STDERR when loading of a plugin
1348 fails.
1349 * apcups plugin: Fix the `types' used to submit the values: They still
1350 has an `apcups_' prefix which doesn't work anymore.
1351 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1352 whatever the client thinks is `now'..
1354 2007-08-26, Version 4.0.7
1355 * documentation: Some typos have been fixed and some information has
1356 been improved.
1357 * build system: Many fixes for detecting libraries in unusual places,
1358 such as on RedHat systems. The affected libraries are `libcurl',
1359 `libmysql', and `libupsclient'.
1360 * network plugin: Allow the `Port' option to be specified as a number
1361 (i. e. without quotes).
1362 * nut plugin: A fix allows linking the nut plugin against
1363 libupsclient, version >= 2.2.0.
1364 * processes plugin: Fix a potential segmentation fault.
1366 2007-07-30, Version 4.0.6
1367 * sensors plugin: Fix the ignorelist functionality: Only the `type
1368 instance' was used to match against the list, but the documentation
1369 told otherwise. This release fixes the code, so it complies with the
1370 documentation.
1371 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1372 configuration messages will end up in the logging facility.
1373 * conrtib/fedora: The contributed specfile for Fedora has been
1374 updated.
1376 2007-07-05, Version 4.0.5
1377 * Portability: More fixes for OpenBSD have been included.
1379 2007-06-24, Version 4.0.4
1380 * cpu plugin: Fixed the Solaris code.
1381 * dns plugin: Fixed a build issue for OpenBSD.
1382 * interface plugin: Fixed the Solaris code.
1383 * load plugin: Fixed the alternative `/proc' Linux code.
1384 * memory plugin: Fixed the Solaris code.
1385 * oconfig: Don't require `-lfl' anymore.
1387 2007-06-19, Version 4.0.3
1388 * cpu plugin: Fix the Darwin / Mac OS X code.
1389 * ping plugin: Use the return value of `getpid', not its address.
1390 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1391 initialized correctly.
1392 * configure: Added `--with-nan-emulation' to aid cross compilation.
1394 2007-06-12, Version 4.0.2
1395 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1396 they're given in numerically form.
1398 2007-06-07, Version 4.0.1
1399 * iptables plugin: A bug in the configuration routine has been fixed.
1400 Setting a comment in the configfile will no longer cause a
1401 segmentation fault.
1403 2007-06-03, Version 4.0.0
1404 * collectd: The plugin-infrastructure has been changed to allow for
1405 more types of plugins, namely `write' and `log' plugins.
1406 * collectd: The read-function has been changed to read many plugins in
1407 parallel, using threads. Thus, plugins generally need to use
1408 thread-safe functions from now on.
1409 * collectd: The '-t' command line options allows to perform syntax tests
1410 of the configuration file and exit immediately.
1411 * csv plugin: The new `csv' plugin handles output to `comma separated
1412 values'-files.
1413 * rrdtool plugin: The new `rrdtool' plugin handles output to
1414 RRD-files. Data can be cached to combine multiple updates into one
1415 write to increase IO-performance.
1416 * network plugin: The new `network' plugin handles IO via the network.
1417 It implements a different, much more extensible protocol which can
1418 combine many values in one packet, decreasing the number of UDP-
1419 packets being sent. It can read from and send to the network and
1420 with the appropriate configuration even forward packets to other
1421 networks.
1422 * unixsock plugin: The new `unixsock' plugin provides an interface to
1423 communicate with the daemon while it is running. Right now the
1424 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1425 come.
1426 * perl plugin: The new `perl' plugin allows you to write extensions
1427 for collectd in the scripting-language Perl.
1428 * logfile plugin: The new `logfile' plugin writes logmessages to files
1429 or STDOUT or STDERR.
1430 * syslog plugin: The new `syslog' plugin sends logmessages to the
1431 system's syslog daemon.
1432 * entropy plugin: The new `entropy' plugin collects the amount of
1433 entropy currently being available to the system.
1434 * exec plugin: The new `exec' plugin forks child processes and reads
1435 back values provided by the forked processes.
1436 * iptables plugin: The new `iptables' plugin reads counters from
1437 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1438 plugin.
1439 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1440 to Peter Holik for contributing this plugin.
1441 * nut plugin: The new `nut' plugin connects the upsd of the `network
1442 ups tools' and reads information about the connected UPS.
1443 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1444 connections) field was added by Florent Monbillard.
1445 * collectd-nagios: The new `collectd-nagios' binary queries values
1446 from collectd, parses them and exits according to Nagios-standards.
1447 * manpages: The manpages have been improved a lot.
1449 2007-09-28, Version 3.11.7
1450 * wireless plugin: Correct the handling of cards returning signal and
1451 noise quality as percentage.
1453 2007-08-31, Version 3.11.6
1454 * processes plugin: Fix a potential segmentation fault.
1456 2007-05-29, Version 3.11.5
1457 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1458 * ntpd plugin: Fix a potential buffer overflow.
1459 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1460 were accounted as `zombies'.
1462 2007-04-10, Version 3.11.4
1463 * dns plugin: Change the order of includes to make the plugin compile
1464 under FreeBSD.
1466 2007-03-30, Version 3.11.3
1467 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1468 of the unused `COLLECT_KSTAT'.
1470 2007-02-11, Version 3.11.2
1471 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1472 NULL-pointer may have been passed to `printf' which causes a
1473 segfault with some libcs.
1475 2007-02-10, Version 3.11.1
1476 * df plugin: Some wrong defines have been fixed so the plugin works
1477 under Solaris again.
1478 * dns plugin: The usage of a struct has been fixed to work with
1479 non-GNU libcs.
1480 * processes plugin: Some missing defines have been added so the plugin
1481 compiles cleanly under FreeBSD and presumably other UNIXes.
1483 2006-12-22, Version 3.11.0
1484 * collectd: The new command line option `-P' makes it easier for
1485 distributors to change the location of PID-files.
1486 * collectd: The daemon shuts down faster now which makes it easier to
1487 write init.d-scripts for it.
1488 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1489 caused problems every now and then.
1490 * df plugin: New config options allow to ignore certain mountpoints,
1491 filesystem types or devices.
1492 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1493 and interprets it. It collects traffic as well as qtype, opcode and
1494 rcode counts.
1495 * email plugin: Sebastian Harl has contributed this plugin which
1496 counts received mails in categories (e. g. ham, spam, virus), spam
1497 score (as given by SpamAssassin) and check types.
1498 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1499 uses `mbmon' to gather information from sensors on the motherboard.
1500 * processes plugin: Collect detailed statistics for configured
1501 processes, that's process and thread count, CPU usage, resident
1502 segment size and pagefaults.
1503 * multimeter plugin: Peter Holik contributed a new plugin which
1504 queries multimeters.
1505 * sensors plugin: Lubos Stanek has put much effort into improving this
1506 plugin, including `extended naming', collection of voltage values
1507 and the possibility to ignore certain values.
1509 2006-12-21, Version 3.10.4
1510 * Max Kellermann has identified a bug in the server routine: When
1511 opening a socket fails the daemon will (re)try opening the socket in
1512 an endless loop, ultimately leading to a `EMFILE' error.
1514 2006-11-04, Version 3.10.3
1515 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1516 ntpd's reply was sent in more than one packet, the buffer size was
1517 calculated incorrectly, resulting in the reading of uninitialized or
1518 freed memory.
1520 2006-11-01, Version 3.10.2
1521 * The sample config file has been improved.
1522 * Errors in the manpages have been corrected.
1523 * The ping-plugin now adds hosts during initialization, not during
1524 startup. This speeds up startup when no network connectivity is
1525 available. Also, the hosts are being added later when the network is
1526 available.
1527 * Improved BSD-support for the df-plugin.
1528 * Fixed syntax errors in the swap-plugin for Mac OS X.
1529 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1530 plugin.
1531 * Don't disable the mysql-plugin if connecting to the database fails
1532 during initialization. Instead, try again in increasing intervals.
1534 2006-07-19, Version 3.10.1
1535 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1536 the apcups cannot be reached, unconnected sockets will pile up and
1537 eventually lead to `Too many open files' errors.
1539 2006-07-09, Version 3.10.0
1540 * The `disk' plugin has been ported to Darwin.
1541 * The `battery' plugin should work on many Apple computers now.
1542 * The `traffic' plugin can now ignore certain interfaces. Also,
1543 statistics for sent/received packets and errors have been added.
1544 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1545 to Anthony Gialluca for contributing this plugin and providing me
1546 with a test environment :)
1547 * A plugin for monitoring an NTP instance and the local clock drift
1548 has been added.
1550 2006-06-25, Version 3.9.4
1551 * The Solaris code in the `swap' plugin has been changed to reflect
1552 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1553 working this out.
1554 * The debugging system has been fixed to work with the Sun libc.
1555 * When built without librrd the variable `operating_mode' could be
1556 uninitialized. Thanks to David Elliot for reporting the bug.
1558 2006-06-01, Version 3.9.3
1559 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1560 operating systems also profit from the changes, but I wasn't able to
1561 check that.
1562 * Changed the build system to find the netinet-includes under FreeBSD
1563 and therefore successfully build the `liboping' library there.
1565 2006-05-09, Version 3.9.2
1566 * Applied a patch to the `liboping' library. Due to a bug in the
1567 sequence checking the `ping' plugin stopped working after
1568 approximately 7.6 days.
1570 2006-05-09, Version 3.8.5
1571 * Applied a patch to the `liboping' library. Due to a bug in the
1572 sequence checking the `ping' plugin stopped working after
1573 approximately 7.6 days.
1575 2006-04-21, Version 3.9.1
1576 * Build issues with Solaris and possible other architectures have been
1577 resolved.
1578 * Problems when building the `apache'-plugin without `libcurl' have
1579 been resolved.
1580 * A bug in the `ping' plugin has been fixed. Sorry folks.
1582 2006-04-02, Version 3.9.0
1583 * A plugin to monitor the Apache webserver has been added.
1584 <http://httpd.apache.org/>
1585 * A plugin to collect statistics about virtual servers using VServer.
1586 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1587 this plugin :)
1588 * A plugin for wireless LAN cards has been added. It monitors signal
1589 strength, link quality and noise ratio..
1590 * A plugin for Apple hardware sensors has been added.
1591 * An option to compile collectd with different `step' and `heartbeat'
1592 settings has been added. The size of RRAs is no longer static but
1593 calculated based on the settings for `step' and `width'.
1594 * The `ping' plugin can now be configured to use a certain TTL.
1595 * A plugin to monitor the hardware sensors of Apple computers has been
1596 added.
1597 * The plugins `cpu', `memory', `processes' and `traffic' have been
1598 ported to Mach/Darwin (Mac OS X).
1599 * The `log mode' has been contributed by Christophe Kalt. It writes
1600 the data into text files rather than RRD files.
1602 2006-04-09, Version 3.8.4
1603 * Applied patch by Vincent Stehlé which improves the disk-name
1604 resolution in the `hddtemp' plugin for Linux systems.
1606 2006-04-02, Version 3.8.3
1607 * Applied a patch by James Byers: The MySQL plugin was not working
1608 with MySQL 5.0.2 or later.
1610 2006-03-14, Version 3.8.2
1611 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1612 the GNU libc, because it points to `/etc/fstab' rather than
1613 `/etc/mtab'.
1615 2006-03-13, Version 3.8.1
1616 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1617 * Fixes in the debian `postinst' and `init.d' scripts.
1619 2006-03-09, Version 3.8.0
1620 * The `ping' plugin no longer uses `libping' but a self written
1621 library named `liboping'. With this library it's possible to ping
1622 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1624 2006-02-18, Version 3.7.2
1625 * A simple bug in the `battery' plugin has been fixed. It should now
1626 work with ACPI based batteries as well. Thanks to Sebastian for
1627 fixing this.
1628 * Fixing a bug that prevented collectd to be built without librrd.
1629 Thanks to Werner Heuser for reporting it.
1631 2006-02-04, Version 3.7.1
1632 * The new network code has been improved to build with older versions
1633 of glibc.
1634 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1635 to Tommie Gannert for this patch.
1637 2006-01-30, Version 3.7.0
1638 * The `battery' plugin has been added. It collects information about
1639 laptop batteries..
1640 * The MySQL plugin has been improved: It now writes two more RRD
1641 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1642 * The `cpufreq' plugin now reads another file since the file it did
1643 read so far causes much overhead in the kernel. Also, you need root
1644 to read the old file, but not to read the new one.
1645 * The `hddtemp' plugin can now be configured to connect to another
1646 address and/or port than localhost.
1647 * The `df' plugin now prefers `statvfs' over `statfs'.
1648 * The network code has been rewritten. collectd now supports unicast
1649 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1650 be set in the configfile.
1652 2006-01-24, Version 3.6.2
1653 * Due to a bug in the configfile handling collectd wouldn't start in
1654 client mode. This released fixes this.
1656 2006-01-20, Version 3.6.1
1657 * Due to a bug in `configure.in' all modules and the binary were
1658 linked against `libmysqlclient'. This issue is solved by this
1659 release.
1661 2006-01-17, Version 3.6.0
1662 * A config file has been added. This allows for loading only specific
1663 plugins.
1664 * A `df' plugin has been added.
1665 * A `mysql' plugin has been added.
1666 * The `ping' plugin doesn't entirely give up hope when a socket error
1667 occurred, but will back of and increase the intervals between tries.
1669 2006-01-21, Version 3.5.2
1670 * Fixed yet another bug in the signal handling.. Stupid typo..
1671 * Improved the ping plugin to not give up on socket errors (backport
1672 from 3.6.0).
1674 2005-12-18, Version 3.5.1
1675 * The PID-file is now deleted correctly when shutting down the daemon.
1676 * SIGINT and SIGTERM are now handled correctly.
1678 2005-12-16, Version 3.5.0 (Revision 326)
1679 * A bug in the `load' module under Solaris has been fixed.
1680 * The `users' module has been contributed by Sebastian Harl. It counts
1681 currently logged in users.
1682 * The CPU module now works under FreeBSD without the use of
1683 `libstatgrab', however SMP support is missing.
1684 * The default directories for the RRD files and the PID file now
1685 depend on the compile time setting of `localstatedir'.
1687 2005-11-15, Version 3.4.0 (Revision 236)
1688 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1689 from gentoo's bugzilla for writing the patch.
1690 * The build dependency for librrd has been removed. Binaries built
1691 without librrd are client-only and will multicast their value as
1692 with the `-c' argument.
1693 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1694 * The newly introduced `-f' switch prevents daemon initialization
1695 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1696 Barcellos for this patch.
1698 2005-11-04, Version 3.3.0 (Revision 216)
1699 * New modules have been added:
1700 - `serial', for monitoring traffic on the serial interfaces
1701 - `nfs', for graphing NFS procedure calls
1702 - `tape', traffic from/to tape devices
1703 * The memory.rrd now accepts more than 4Gig of memory.
1705 2005-10-26, Version 3.2.0 (Revision 200)
1706 * Support for graphing the processes has been added (thanks to Lyonel
1707 Vincent)
1708 * If reading from hddtemp fails collectd will increase the time
1709 between polls up to one day.
1710 * The init.d files have been improved.
1711 * Problems with the spec file have been fixed.
1713 2005-10-16, Version 3.1.0 (Revision 194)
1714 * Added the `setsid' syscall to the startup code.
1715 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1717 2005-09-30, Version 3.0.0 (Revision 184)
1718 * The ability to send/receive data to/from the network (think
1719 multicast) has been added.
1720 * Modules have been split up into shared libraries can be loaded at
1721 runtime. The biggest advantage is that the core program doesn't need
1722 to be linked against an external library.
1723 * A patch by George Kargiotakis has been applied: It fixes the sensors
1724 behaviour then more than one sensor is being queried.
1726 2005-09-16, Version 2.1.0 (Revision 172)
1727 * A module for swap statistics has been added.
1729 2005-09-09, Version 2.0.0 (Revision 135)
1730 * Filenames can no longer be configured at program startup. The only
1731 options as of this version are the directory and ping hosts.
1732 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1733 Soft-IRQ statistics are added to `System'.
1734 * Diskstats now collect read and write bytes, not sectors.
1735 * Ping statistics can now be collected for more than one host. There
1736 is no default any more: If no host is given no host will be pinged.
1737 * A self-written patch for libping has been applied so it builds
1738 cleanly.
1740 2005-09-01, Version 1.8.1 (Revision 123)
1741 * Much improved configure-script: libraries and features may now be
1742 disabled.
1743 * More detailed warnings/error messages when RRD update fails.
1745 2005-08-29, Version 1.8.0:
1746 * Support for collecting disk statistics under Solaris.
1748 2005-08-25, Version 1.7.0:
1749 * Support for libstatgrab[1] for load, memory usage and network
1750 traffic. CPU- and disk-usage are not (yet) supported, since
1751 libstatgrab returns insufficient information. I will contact the
1752 authors.
1753 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1754 aren't necessarily counted linear which is now handled correctly.
1755 [1]: http://www.i-scream.org/libstatgrab/
1757 2005-08-21, Version 1.6.0:
1758 * Basic support for Solaris: System load and cpu-usage can be
1759 collected under Solaris, too. Other stats will follow later.
1760 * Many fixes in the autoconf-script
1761 * Collection/Museum scripts have been added under contrib/museum
1762 * collectd may now be started in unprivileged mode, though ping
1763 statistics will not work.
1765 2005-07-17, Version 1.5.1:
1766 * Diskstats-RRDs now use major/minor for naming. Some systems have
1767 weird strings as disk-names..
1769 2005-07-17, Version 1.5:
1770 * A new module, diskstats, has been added. It collects information
1771 about the disks and partitions.
1773 2005-07-11, Version 1.4.2:
1774 * The meminfo module has been changed to work with more platforms
1775 and/or kernel versions.
1777 2005-07-10, Version 1.4.1: Correct traffic stats
1778 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1779 forgot to correct when I changed that module.
1781 2005-07-09, Version 1.4: More traffic stats
1782 * Traffic is now collected for all interfaces that can be found
1783 * Temperature-statistics are read from lm-sensors if available
1785 2005-07-08, Version 1.3: CPU stats
1786 * Collecting CPU statistics now
1788 2005-07-12, Version 1.2: Using syslog
1789 * collectd is now using the syslog facility to report errors, warnings
1790 and the like..
1791 * The default directory is now /var/db/collectd
1793 2005-07-10, Version 1.1: Minor changes
1794 * Nothing really useful to say ;)
1796 2005-07-09, Version 1.0: Initial Version
1797 * The following modules are provided:
1798 * Load average
1799 * Ping time
1800 * Traffic
1801 * Memory info
