603 * collectd: Fix a possible but very rare invalid “free” in the caching
604 code. Thanks to Sebastian Harl for the patch.
605 * collectd: Remove old values when a cache entry is marked as missing.
606 This way the “GETVAL” command of the UnixSock plugin doesn't return
607 old, no longer valid values when this happens. Thanks to Andrés J.
608 Díaz for the patch.
609 * collectd: The “plugin_unregister_read” function has been fixed.
610 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library

616 Thanks to Sebastian Harl for the patch. The build system has been
617 updated to the plugin only includes the shipped header files when it
618 is linked with the shipped library, too.
619 * java plugin: Delay creating the JVM until after the daemon has
620 forked. The JVM internally creates threads that are lost when
621 forking. This means that Java-based plugins are now configured
622 during the init-phase, i. e. later than other plugins.
623 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
624 to Alan Pevec for the patch.
625 * network plugin: Fix the handling of the “CacheFlush” option: The

647 details have been added to the configuration summary. Support for
648 libtool 2.2 has been added.
649 * collectd: Two bugs with the threshold checking have been fixed. The
650 first one prevented thresholds to be checked at all, the second one
651 caused wrong behavior with the persistency option. Thanks to Andrés
652 J. Díaz for fixing these problems.
653 * collectd: Handling of the `Include' configuration option has been
654 fixed.
655 * rrdtool plugin: Make sure initialization is run only once. This
656 resolves problems under Solaris and potentially other systems.
657 Thanks to Amit Gupta for reporting this bug.
658 * java plugin: Make it possible to use dots ('.') instead of slashes
659 ('/') as the class separator. Thanks to Randy Rizun for pointing
660 this out.

672 Linux' file-system based caching framework. Thanks to Edward
673 Konetzko for the patch.
674 * gmond plugin: The new gmond plugin can receive and interpret
675 multicast traffic from Ganglia's gmond daemon.
676 * java plugin: The new java plugin exports the collectd API to Java,
677 making it possible to write extensions to collectd in Java.
678 * memcachec plugin: The new memcachec plugin queries data from a
679 memcached daemon and parses it similar to the cURL plugin. Thanks to
680 Doug MacEachern for the initial code.
681 * memcached plugin: Support for connections over UNIX domain sockets
682 has been added. Thanks to Franck Lombardi for the patch.
683 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

697 structured files, such as many files beneath /proc.
698 * ted plugin: The new TED plugin reads power consumption measurements
699 from “The Energy Detective” (TED). Thanks to Eric Reed for this
700 plugin.
701 * onewire plugin: The new `Interval' option allows collecting
702 information from OneWire sensors at arbitrary intervals.
703 * ping plugin: Support for collecting the drop rate and standard
704 deviation of round-trip times has been added.

706 uptime. Thanks to Marco Chiappero for the patch.
708 2009-09-10, Version 4.6.5
709 * collectd: Remove old values when a cache entry is marked as missing.
710 This way the “GETVAL” command of the UnixSock plugin doesn't return
711 old, no longer valid values when this happens. Thanks to Andrés J.
712 Díaz for the patch.
713 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
714 to follow redirects. Thanks to Joey Hess for reporting this bug.

735 for reporting the bug.
737 2009-06-02, Version 4.6.3
738 * Build system, various plugins: Many build fixes for FreeBSD,
739 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
740 for many fixes and providing a build system for many platforms,
741 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
742 providing an OpenBSD system.
743 * collectd: Two bugs with the threshold checking have been fixed. The
744 first one prevented thresholds to be checked at all, the second one
745 caused wrong behavior with the persistency option. Thanks to Andrés
746 J. Díaz for fixing these problems.
747 * collectd: Handling of the `Include' configuration option has been
748 fixed.
749 * battery plugin: Don't complain about a missing directory every
750 interval.
751 * exec plugin: Allow executed programs to close STDERR. Thanks to
752 Thorsten von Eicken for reporting this problem.
753 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
754 Tomasz Pala for the patch.
755 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
756 the patch.
757 * memory plugin: Fix a potential problem under Solaris.
758 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
759 to Doug MacEachern for the patch.
761 2009-03-18, Version 4.6.2
762 * collectd: Some Solaris utility code has been improved.
763 * filter subsystem: Allow `Chains' without default targets.
764 * liboping: A patch to comply with strict aliasing rules has been
765 added.
766 * timediff match: Fix a typo: The match was registered with a wrong
767 name which prevented this match to be used as documented. Thanks to
768 Bruno Prémont for finding this problem.
769 * bind plugin: Fix collection of the cached RR sets. The number of RR
770 sets currently in the cache was collected as a counter value, which
771 is nonsense. Thanks to Bruno Prémont for implementing this.
772 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
773 primarily BSDs, don't take it well and crash.
774 * oracle plugin: Portability to 64 bit systems has been improved.
775 * postgresql plugin: The default configuration has been improved.
776 * rrdtool plugin: Fix a possible race condition: If the network plugin
777 is brought and dispatches a value before the rrdtool plugin is
778 initialized, the daemon may crash.
780 2009-02-22, Version 4.6.1
781 * collectd: Many documentation fixes.
782 * Collectd::Unixsock: Error handling has been improved.
783 * regex match: Don't link with the PCRE library.
784 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
785 for finding and fixing most of them.
786 * ipmi plugin: Fix an off-by-one error which could cause segmentation
787 faults. Thanks to Peter Holik for his patch.
789 2009-02-16, Version 4.6.0
790 * collectd: Added the `filter chain' infrastructure, which allows the
791 user to use `matches' and `targets' to control value processing.
792 * collectd: The new `-T' command line argument allows more in-depth
793 testing of a configuration. Thanks to Doug MacEachern for the patch.
794 * collectd-nagios: The Nagios integration command has been updated to
795 use libcollectdclient. The `percentage' aggregation function has
796 been added. Thanks to Fabian Linzberger for the patch.
797 * libcollectdclient: A library which abstracts communication with the
798 unixsock plugin for clients has been added.
799 * regex match: Match values by their identifies using regular
800 expressions.
801 * timediff match: Match for values with an invalid timestamp.
802 * value match: Select values by their data sources' values.
803 * notification target: Create and dispatch a notification.
804 * replace target: Replace parts of an identifier using regular
805 expressions.
806 * set target: Set (overwrite) entire parts of an identifier.
807 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
808 statistics, allowing very detailed name server statistics. Thanks to
809 Bruno Prémont for this plugin.
810 * cpu plugin: Report `interrupt' separately when using
811 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
812 example for native OpenBSD support, has been added. Thanks to Simon
813 Kuhnle for the patch.
814 * csv plugin: Make it possible to write values to STDOUT instead of
815 files. This is meant for testing purposes mostly. The output written
816 to STDOUT is compatible with the exec plugin. Thanks to Doug
817 MacEachern for the patch.
818 * curl plugin: This new plugin can be used to read web pages and parse
819 them using the same mechanism that's used in the tail plugin.
820 * dbi plugin: This new plugin allows you to connect to a variety of
821 relational databases and use SQL to gather custom statistics from
822 it. It is similar to the already existing PostgreSQL plugin but uses
823 libdbi to communicate with the database(s).
824 * interface plugin: Use the ignorelist framework when selecting /
825 ignoring interfaces. This allows one to use regular expressions to
826 select interfaces, too.
827 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
828 Thanks to Bruno Prémont for this patch.
829 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
830 for the patch.
831 * mysql plugin: Allow connecting to a database via the UNIX domain
832 socket, too. Thanks to Mirko Buffoni for the patch.
833 * network plugin: Further performance improvements for the receive
834 code. This hopefully will help very large setups.

836 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
837 * oracle plugin: This new plugin allows you to connect to an Oracle
838 database and use SQL to gather custom statistics from it. It is
839 similar to the already existing PostgreSQL plugin.
840 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
841 have been added.
842 * perl plugin: Export the newly added plugin_write() to Perl plugins.
843 * perl plugin: Added support for `notification meta data'.
844 * perl plugin: Added support for the `filter chain' infrastructure by
845 allowing plugins to register `matches' and `targets'.
846 * postgresql plugin: The preferred configuration syntax has been
847 updated to be in line with the syntax used by the new dbi and oracle
848 plugins. The compatibility code for the old syntax is present.
849 Support for the new `Result' blocks and the interval parameter has
850 been added.
851 * processes plugin: Stacksize and virtual memory usage statistics have
852 been added. Portability fixes.
853 * rrdcached plugin: This new plugin uses the (still in development)
854 RRD accelerator daemon, rrdcached. This daemon works very similar to
855 the original rrdtool plugin of collectd, but adds some more nice
856 features.
857 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
858 added.
860 2009-05-09, Version 4.5.4
861 * Build system, various plugins: Many build fixes for FreeBSD,
862 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
863 for many fixes and providing a build system for many platforms,
864 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
865 providing an OpenBSD system.
866 * collectd: Fix a potential race condition when creating directories.
867 * battery plugin: Don't complain about a missing directory every
868 interval.
869 * dns plugin: Slight portability fixes.
870 * exec plugin: Allow executed programs to close STDERR. Thanks to
871 Thorsten von Eicken for reporting this problem.
872 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
873 Tomasz Pala for the patch.
874 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
875 the patch.
876 * rrdtool plugin: Fix a possible race condition: If the network plugin
877 is initialized and dispatches a value before the rrdtool plugin is
878 initialized, the daemon may crash.
879 * memory plugin: Fix a potential problem under Solaris.
881 2009-02-22, Version 4.5.3
882 * build system: The check for libupsclient even when `pkg-config' is
883 not available.
884 * collectd: Fix error handling in the global cache.
885 * Collectd::Unixsock: Error handling has been improved.
886 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
887 patch.
888 * ipmi plugin: Fix an off-by-one error which could cause segmentation
889 faults. Thanks to Peter Holik for his patch.
890 * tcpconns plugin: An endianness problem has been fixed in the *BSD
891 code. Thanks to "thated" for reporting this.
893 2009-01-02, Version 4.5.2
894 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
895 file may be in both locations, especially when the database was
896 installed in a non-standard path. Thanks to Dusty Doris for
897 reporting this.
898 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
899 Solaris, in the configure script automatically.
900 * build system, tcpconns plugin: Check for `kvm_nlist' and
901 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
902 library with similar functions to the BSD variant, but doesn't
903 provide these necessary functions.
904 * collectd.conf(5): Various fixes and clarifications.
905 * collectd: Remove a GNUism (unnamed unions), thus improving
906 portability.
907 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
908 This solves portability problems, especially for Solaris.
909 * dns plugin: Fix a portability problem with NetBSD.
910 * filecount plugin: Fix an off-by-one error. This error may cause a
911 segmentation fault.
912 * network plugin: Fix the handling of `type' in the network protocol.
913 Due to a programming mistake, only 4 or 8 bytes would be copied to a
914 much larger buffer. This caused the `type' to be transferred much
915 more often than necessary. In some cases, e. g. the `cpu' and
916 `cpufreq' plugins being used at the same time, data may be corrupted
917 in those files. Thanks to Bruno Prémont for debugging and reporting
918 this issue.
919 * processes plugin: Fix a possible segmentation fault when specifying
920 invalid configuration options.
921 * unixsock plugin: Make sure the initialization function is run only
922 once. This resolves a file descriptor leak under systems which run
923 the initialization more than once, such as Solaris.
925 2008-10-16, Version 4.5.1
926 * build system: Change `--enable-<plugin>' to abort with an error if
927 dependencies are not met. Thanks to Bruno Prémont for the patch.
928 Also, the poisoning of various string functions has been restricted
929 to debug builds.
930 * collectd: Fix a memory leak in the global value cache. With every
931 *missing* value a couple of bytes would be leaked. Another memory
932 leak in the configuration handling code has been fixed. Thanks to
933 Niraj Tolia for reporting these issues.
934 * collectd: Fix an off-by-one error in the ignorelist functionality.
935 When using regular expressions, the last character would be missing,
936 possibly matching differently from what one would expect.
937 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
938 problem.
939 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
940 Linzberger for reporting the bug.
941 * iptables plugin: Fix an off-by-one error. If a string was just one
942 character too long, it was truncated instead of reporting an error.
943 * network plugin: Fix a memory leak in the configuration handling
944 code. Thanks to Niraj Tolia for reporting this issue.
945 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
946 * postgresql plugin: Don't reopen connection during reinitialization.
947 This fixes a bug under Solaris and potentially other platforms.
948 Missing calls to `PQclear' have been added, too. This fixes memory
949 leaks. Thanks to ``Admin'' for reporting these bugs.
950 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
951 library.
952 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
953 problems with some `libc's. Thanks to Matthias Lay for reporting the
954 bug.
956 2008-09-04, Version 4.5.0
957 * collectd: Added the ability to flush certain identifiers.
958 * collectd: The concept of `notification meta data' has been
959 introduced.
960 * filecount plugin: The new filecount plugin counts the number of
961 files in a directory and its subdirectories.
962 * ipmi plugin: Sensor names have been changed to ensure unique names.
963 Notifications upon added and removed sensors can now be generated.
964 * notify_desktop plugin: This new plugin sends notifications to the
965 X desktop using the structure defined in the `Desktop Notification
966 Specification'.
967 * notify_email plugin: This new plugin sends out notifications via
968 email, using the `esmtp' library.
969 * onewire plugin: The new experimental(!) onewire plugin reads values,
970 such as temperatures, from sensors connected to the computer via the
971 onewire bus.
972 * perl plugin: Improved synchronized access to internal data structures
973 and fixed a possible dead-lock.
974 * perl plugin: Added the ability to flush certain identifiers and marked
975 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
976 plugin_flush().
977 * perl plugin: Added the ability to configure Perl plugins.
978 * postgresql plugin: The new postgresql plugin collects statistics
979 about or from a PostgreSQL database.
980 * processes plugin: The `ProcessMatch' option has been added.
981 * rrdtool plugin: Implement throttling of the `update queue' to lessen
982 IO load.
983 * tcpconns plugin: This plugin has been ported to OpenBSD.
984 * thermal plugin: The new thermal plugin collects system temperatures
985 using Linux ACPI thermal zone data.
987 2009-01-02, Version 4.4.5
988 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
989 file may be in both locations, especially when the database was
990 installed in a non-standard path. Thanks to Dusty Doris for
991 reporting this.
992 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
993 Solaris, in the configure script automatically.
994 * collectd.conf(5): Various fixes and clarifications.
995 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
996 portability problems, especially for Solaris.
997 * dns plugin: Fix a portability problem with NetBSD.
998 * network plugin: Fix the handling of `type' in the network protocol.
999 Due to a programming mistake, only 4 or 8 bytes would be copied to a
1000 much larger buffer. This caused the `type' to be transferred much
1001 more often than necessary. In some cases, e. g. the `cpu' and
1002 `cpufreq' plugins being used at the same time, data may be corrupted
1003 in those files. Thanks to Bruno Prémont for debugging and reporting
1004 this issue.
1005 * unixsock plugin: Make sure the initialization function is run only
1006 once. This resolves a file descriptor leak under systems which run
1007 the initialization more than once, such as Solaris.
1009 2008-10-16, Version 4.4.4
1010 * build system: Change `--enable-<plugin>' to abort with an error if
1011 dependencies are not met. Thanks to Bruno Prémont for the patch.
1012 Also, the poisoning of various string functions has been restricted
1013 to debug builds.
1014 * collectd: Fix a memory leak in the global value cache. With every
1015 *missing* value a couple of bytes would be leaked. Another memory
1016 leak in the configuration handling code has been fixed. Thanks to
1017 Niraj Tolia for reporting these issues.
1018 * collectd: Fix an off-by-one error in the ignorelist functionality.
1019 When using regular expressions, the last character would be missing,
1020 possibly matching differently from what one would expect.
1021 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
1022 problem.
1023 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
1024 Linzberger for reporting the bug.
1025 * network plugin: Fix a memory leak in the configuration handling
1026 code. Thanks to Niraj Tolia for reporting this issue.
1027 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
1028 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
1029 problems with some `libc's. Thanks to Matthias Lay for reporting the
1030 bug.
1032 2008-09-01, Version 4.4.3
1033 * collectd: Fix a memory leak in the threshold checking code.
1034 * memcached plugin: Fix a too short timeout and a related file
1035 descriptor leak.
1036 * memory plugin: A typo in the libstatgrab code has been fixed.
1037 * snmp plugin: Fix a possible memory leak.
1039 2008-07-15, Version 4.4.2
1040 * build system: Use pkg-config to detect the upsclient library.
1041 * collectd: Try even harder to determine the endianess of the
1042 architecture collectd is being built on.
1043 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
1044 of disks.
1045 * dns plugin: Fix compilation errors with BIND versions 19991001
1046 through 19991005.
1047 * network plugin: Bugfix in the init routine: The init function
1048 cleared a buffer regardless of its contents. This could lead to lost
1049 values under Solaris.
1050 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
1051 * vserver plugin: Remove usage of the thread-unsafe `readdir'
1052 function.
1053 * wireless plugin: Work around incorrect noise and power values
1054 returned by some broken drivers.
1056 2008-06-03, Version 4.4.1
1057 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
1058 to kyrone for reporting this.
1059 * collectd: Fixed min/max output in notifications generated by
1060 threshold checking.
1061 * collectd-nagios: Fix the protocol used to communicate with the
1062 daemon.
1063 * perl plugin: Fail noisily, but don't shutdown the daemon, if
1064 initialization has errors. An issue with Perl 5.10 has been fixed.
1065 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
1066 René Rebe and Siegmund Gorr for reporting this.
1068 2008-05-06, Version 4.4.0
1069 * collectd: Internal code cleanups.
1070 * collectd: Added support for a `Flush' command in the unixsock and
1071 exec plugins. This command can be used to force a plugin (or all) to
1072 flush its values to disk.
1073 * collectd: Thresholds can now be configured to apply to one data
1074 source only, making it possible to configure different thresholds
1075 for each data source.
1076 * apache, nginx plugins: Added the possibility to disable host and/or
1077 peer verification.
1078 * ascent plugin: The new ascent plugin reads and parses the statistics
1079 page of an Ascent server.
1080 * cpu plugin: Support for the statgrab library has been added.
1081 * disk plugin: The possibility to ignore certain disks or collect only
1082 specific disks has been added.
1083 * disk plugin: Support for the statgrab library has been added.
1084 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
1085 sensor values via IPMI, the intelligent platform management
1086 interface.
1087 * iptables plugin: The iptc library that is used by the iptables
1088 plugin has been added to the distribution, because it is not
1089 provided by all distributions and removed from at least one.
1090 * powerdns plugin: The new powerdns plugin reads statistics from an
1091 authoritative or a recursing PowerDNS name server.
1092 * rrdtool plugin: The size of the files generated with the default
1093 configuration has been decreased.
1094 * tail plugin: The new tail plugin can be used to gather statistics by
1095 continuously reading from log files.
1096 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1097 TeamSpeak2 server and collects statistics about the number of users
1098 and number of channels.
1099 * users plugin: Support for the statgrab library has been added.
1100 * vmem plugin: The new vmem plugin collects very detailed statistics
1101 about the virtual memory subsystem of Linux.
1103 2008-08-30, Version 4.3.4
1104 * Build system: Improved detection of and linking with the statgrab
1105 library.
1106 * collectd: Portability fixes, especially to determine endianess more
1107 reliable.
1108 * Various plugins: Fix format strings.
1109 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1110 again has been applied.
1111 * memcached plugin: Fix a too short timeout and a related file
1112 descriptor leak.
1113 * memory plugin: A typo in the libstatgrab code has been fixed.
1114 * network plugin: A fix in the initialization function solves problems
1115 under Solaris.
1116 * nginx plugin: A thread-unsafe function has been replaced.
1117 * vserver plugin: A thread-unsafe function has been replaced.
1118 * wireless plugin: A work-around for broken wireless drivers has been
1119 added.
1121 2008-04-22, Version 4.3.3
1122 * build system: Improved detection of several libraries, especially if
1123 they are in non-standard paths.
1124 * build system: Portability fixes: Automatically define "_REENTRANT"
1125 if the libc expects it.
1126 * collectd: Error and warning messages have been improved.
1127 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1128 using them.
1129 * apache plugin: Allocate new memory when reading a webpage instead of
1130 using a buffer of static size.
1131 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1132 the program.
1133 * hddtemp plugin: Error and warning messages have been improved.
1134 * sensors plugin: Fix sensor collection for some chip types.
1136 2008-03-29, Version 4.3.2
1137 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1138 `Persist' threshold options.
1139 * collectd: Fix handling of missing values in the global value cache.
1140 * collectd: Improved error messages when parsing the configuration.
1141 * sensors plugin: Fix temperature collection with libsensors4.
1142 * unixsock plugin: Fix mixed input and output operation on streams.
1143 * wireless plugin: Fix reading noise value.
1145 2008-03-05, Version 4.3.1
1146 * exec plugin: Set supplementary group IDs.
1147 * network plugin:
1148 + Use `memcpy' when constructing/parsing a package to avoid
1149 alignment problems on weird architectures, such as Sparc.
1150 + Translate doubles to/from the x86 byte representation to ensure
1151 cross-platform compatibility.
1152 * ping plugin: Correct the handling of the `TTL' setting.
1153 * swap plugin: Reapply a patch for Solaris.
1154 * tcpconns plugin: Portability improvements.
1156 2008-02-18, Version 4.3.0
1157 * collectd: Notifications have been added to the daemon. Notifications
1158 are status messages that may be associated with a data instance.
1159 * collectd: Threshold checking has been added to the daemon. This
1160 means that you can configure threshold values for each data
1161 instance. If this threshold is exceeded a notification will be
1162 created.
1163 * collectd: The new `FQDNLookup' option tells the daemon to use the
1164 full qualified domain name as the hostname, not just the host part
1165 es returned by `gethostname(2)'.
1166 * collectd: Support for more than one `TypesDB' file has been added.
1167 This is useful when one such file is included in a package but one
1168 wants to add custom type definitions.
1169 * collectd: The `Include' config option has been expanded to handle
1170 entire directories and shell wildcards.
1171 * collectdmon: The new `collectdmon' binary detects when collectd
1172 terminates and automatically restarts it again.
1173 * csv plugin: The CSV plugin is now able to store counter values as a
1174 rate, using the `StoreRates' configuration option.
1175 * exec plugin: Handling of notifications has been added and the
1176 ability to pass arguments to the executed programs has been added.
1177 * hddtemp plugin: The new `TranslateDevicename' option lets you
1178 disable the translation from device names to major-minor-numbers.
1179 * logfile plugin: Handling of notifications has been added.
1180 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1181 domain name lookups in this plugin.
1182 * perl plugin: Many internal changes added support for handling multiple
1183 threads making the plugin reasonably usable inside collectd. The API has
1184 been extended to support notifications and export global variables to
1185 Perl plugins; callbacks now have to be identified by name rather than a
1186 pointer to a subroutine. The plugin is no longer experimental.
1187 * uuid plugin: The new UUID plugin sets the hostname to an unique
1188 identifier for this host. This is meant for setups where each client
1189 may migrate to another physical host, possibly going through one or
1190 more name changes in the process. Thanks to Richard Jones from
1191 Red Hat's Emerging Technology group for this plugin.
1192 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1193 CPU, disk and network statistics about guest systems on the same
1194 physical server. Thanks to Richard Jones from Red Hat's Emerging
1195 Technology group for this plugin.
1197 2008-04-22, Version 4.2.7
1198 * build system: Improved detection of several libraries, especially if
1199 they are in non-standard paths.
1200 * build system: Portability fixes: Automatically define "_REENTRANT"
1201 if the libc expects it.
1202 * collectd: Error and warning messages have been improved.
1203 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1204 using them.
1205 * apache plugin: Allocate new memory when reading a webpage instead of
1206 using a buffer of static size.
1207 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1208 the program.
1209 * hddtemp plugin: Error and warning messages have been improved.
1210 * sensors plugin: Fix sensor collection for some chip types.
1212 2008-03-29, Version 4.2.6
1213 * collectd: Improved error messages when parsing the configuration.
1214 * sensors plugin: Fix temperature collection with libsensors4.
1215 * unixsock plugin: Fix mixed input and output operation on streams.
1216 * wireless plugin: Fix reading noise value.
1218 2008-03-04, Version 4.2.5
1219 * apache plugin: Improved initialization and error messages.
1220 * exec plugin: Set supplementary group IDs.
1221 * network plugin:
1222 + Create separate threads for reading from the socket and parsing
1223 and dispatching incoming packets. Versions prior to this may have
1224 problems in high-load situations, where the socket receive buffers
1225 overflows, resulting in gaps in the data.
1226 + Use `memcpy' when constructing/parsing a package to avoid
1227 alignment problems on weird architectures, such as Sparc.
1228 + Translate doubles to/from the x86 byte representation to ensure
1229 cross-platform compatibility.
1230 * ping plugin: Correct the handling of the `TTL' setting.
1231 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1232 * swap plugin: Reapply a patch for Solaris.
1233 * tcpconns plugin: Portability improvements.
1235 2008-01-21, Version 4.2.4
1236 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1237 the permission on the socket as documented in the manpage. Thanks to
1238 Evgeny Chukreev for fixing this issue.
1239 * collectd: The documentation has been improved.
1241 2007-12-28, Version 4.2.3
1242 * sensors plugin: Updated the plugin to build and work with version 3
1243 of the libsensors library.
1245 2007-12-15, Version 4.2.2
1246 * nginx plugin: Incorrect comparison of strings lead to a segfault
1247 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1248 this.
1249 * logfile plugin: The config option `Timestamp' was handled
1250 incorrectly and basically always active. Thanks to Luke Heberling
1251 for fixing this.
1253 2007-11-08, Version 4.2.1
1254 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1255 enabled on the host.
1256 * snmp plugin: Fix a memory leak.
1258 2007-10-27, Version 4.2.0
1259 * collectd: The new config option `Include' lets you include other
1260 configfiles and thus split up your config into smaller parts. This
1261 may be especially interesting for the snmp plugin to keep the data
1262 definitions separate from the host definitions.
1263 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1264 (number of connections, octets and packets for each service and
1265 destination). Thanks to Sebastian Harl for this plugin.
1266 * memcached plugin: The new `memcached' plugin connects to a memcached
1267 daemon process and collects statistics of this distributed caching
1268 system. Thanks to Antony Dovgal for contributing this plugin.
1269 * nginx plugin: The new `nginx' plugin reads the status page of an
1270 nginx daemon and saves the handled connections and requests.
1271 * perl plugin: Many changes, including the added `EnableDebugger'
1272 config option which lets you debug your Perl plugins more easily.
1273 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1274 be more thread-safe otherwise by locking calls to the library.
1275 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1276 correct the values returned by SNMP-agents. If a <data> block is
1277 defined as `table' the instance is now optional. The sequence number
1278 is used as the type-instance in this case. The new `InstancePrefix'
1279 option allows to add arbitrary prefixes to the type-instance.
1280 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1281 certain TCP connections and what state they're in. This can be used
1282 to see how many connections your FTP server has to handle or how
1283 many outgoing connections your mailserver has open.
1285 2008-01-11, Version 4.1.6
1286 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1287 the permission on the socket as documented in the manpage. Thanks to
1288 Evgeny Chukreev for fixing this issue.
1289 * collectd: The documentation has been improved.
1291 2007-12-27, Version 4.1.5
1292 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1293 memory situations.
1294 * sensors plugin: Updated the plugin to build and work with version 3
1295 of the libsensors library.
1297 2007-11-08, Version 4.1.4
1298 * Build system: Improve detection of the rrd library, especially if
1299 it's in a non-standard location.
1300 * Build system: A bug when parsing the argument for
1301 `--with-libnetsnmp' has been fixed.
1302 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1303 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1304 a deadlock or delay when shutting down the daemon.
1305 * snmp plugin: Fix a memory leak.
1307 2007-10-24, Version 4.1.3
1308 * collectd: A build issue under Solaris has been resolved by renaming
1309 data types.
1310 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1311 be more thread-safe otherwise by locking calls to the library.
1313 2007-09-28, Version 4.1.2
1314 * apcups plugin: Fix reporting of the `load percent' data.
1315 * wireless plugin: Correct the handling of cards returning signal and
1316 noise quality as percentage.
1317 * perl plugin: Fix a possible buffer overflow in get_module_name().
1318 * build system: Further improve the detection of libraries.
1319 * netlink plugin: Build issues under some older versions of the Linux
1320 includes (i. e. Debian Sarge) have been fixed.
1321 * snmp plugin: Fix a potential segfault when a host times out. Add
1322 support for the `timeticks' type.
1324 2007-09-12, Version 4.1.1
1325 * Build system: The detection of `libnetlink' has been improved.
1326 * collectd: The documentation has been fixed in numerous places.
1327 * exec plugin: Setting the group under which to run a program has been
1328 fixed.
1329 * collectd: The `sstrerror' function was improved to work correctly
1330 with the broken GNU version of `strerror_r'.
1331 * collectd: Write an error message to STDERR when loading of a plugin
1332 fails.
1333 * apcups plugin: Fix the `types' used to submit the values: They still
1334 has an `apcups_' prefix which doesn't work anymore.
1335 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1336 whatever the client thinks is `now'..
1338 2007-09-01, Version 4.1.0
1339 * Build system: The build system has been changed to automatically
1340 disable all plugins, which are missing dependencies. The dependency
1341 checking has been removed from the plugins themselves to remove
1342 redundancy.
1343 * Flexible interval: The interval of collected data is now sent along
1344 with the data itself over the network, so that the interval-settings
1345 of server and clients no longer needs to match.
1346 * netlink plugin: The new `netlink' plugin connects to the Linux
1347 kernel using a netlink socket and uses it to query information about
1348 interfaces, qdiscs and classes.
1349 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1350 to not block data collection.
1351 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1352 network devices, such as switches, routers, thermometers, rack
1353 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1354 plugin.
1355 * unixsock plugin: Added the `LISTVAL' command.
1356 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1357 of music played with xmms.
1359 2007-09-28, Version 4.0.9
1360 * apcups plugin: Fix reporting of the `load percent' data.
1361 * wireless plugin: Correct the handling of cards returning signal and
1362 noise quality as percentage.
1363 * perl plugin: Fix a possible buffer overflow in get_module_name().
1365 2007-09-12, Version 4.0.8
1366 * collectd: The `sstrerror' function was improved to work correctly
1367 with the broken GNU version of `strerror_r'.
1368 * collectd: Write an error message to STDERR when loading of a plugin
1369 fails.
1370 * apcups plugin: Fix the `types' used to submit the values: They still
1371 has an `apcups_' prefix which doesn't work anymore.
1372 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1373 whatever the client thinks is `now'..
1375 2007-08-26, Version 4.0.7
1376 * documentation: Some typos have been fixed and some information has
1377 been improved.
1378 * build system: Many fixes for detecting libraries in unusual places,
1379 such as on RedHat systems. The affected libraries are `libcurl',
1380 `libmysql', and `libupsclient'.
1381 * network plugin: Allow the `Port' option to be specified as a number
1382 (i. e. without quotes).
1383 * nut plugin: A fix allows linking the nut plugin against
1384 libupsclient, version >= 2.2.0.
1385 * processes plugin: Fix a potential segmentation fault.
1387 2007-07-30, Version 4.0.6
1388 * sensors plugin: Fix the ignorelist functionality: Only the `type
1389 instance' was used to match against the list, but the documentation
1390 told otherwise. This release fixes the code, so it complies with the
1391 documentation.
1392 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1393 configuration messages will end up in the logging facility.
1394 * conrtib/fedora: The contributed specfile for Fedora has been
1395 updated.
1397 2007-07-05, Version 4.0.5
1398 * Portability: More fixes for OpenBSD have been included.
1400 2007-06-24, Version 4.0.4
1401 * cpu plugin: Fixed the Solaris code.
1402 * dns plugin: Fixed a build issue for OpenBSD.
1403 * interface plugin: Fixed the Solaris code.
1404 * load plugin: Fixed the alternative `/proc' Linux code.
1405 * memory plugin: Fixed the Solaris code.
1406 * oconfig: Don't require `-lfl' anymore.
1408 2007-06-19, Version 4.0.3
1409 * cpu plugin: Fix the Darwin / Mac OS X code.
1410 * ping plugin: Use the return value of `getpid', not its address.
1411 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1412 initialized correctly.
1413 * configure: Added `--with-nan-emulation' to aid cross compilation.
1415 2007-06-12, Version 4.0.2
1416 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1417 they're given in numerically form.
1419 2007-06-07, Version 4.0.1
1420 * iptables plugin: A bug in the configuration routine has been fixed.
1421 Setting a comment in the configfile will no longer cause a
1422 segmentation fault.
1424 2007-06-03, Version 4.0.0
1425 * collectd: The plugin-infrastructure has been changed to allow for
1426 more types of plugins, namely `write' and `log' plugins.
1427 * collectd: The read-function has been changed to read many plugins in
1428 parallel, using threads. Thus, plugins generally need to use
1429 thread-safe functions from now on.
1430 * collectd: The '-t' command line options allows to perform syntax tests
1431 of the configuration file and exit immediately.
1432 * csv plugin: The new `csv' plugin handles output to `comma separated
1433 values'-files.
1434 * rrdtool plugin: The new `rrdtool' plugin handles output to
1435 RRD-files. Data can be cached to combine multiple updates into one
1436 write to increase IO-performance.
1437 * network plugin: The new `network' plugin handles IO via the network.
1438 It implements a different, much more extensible protocol which can
1439 combine many values in one packet, decreasing the number of UDP-
1440 packets being sent. It can read from and send to the network and
1441 with the appropriate configuration even forward packets to other
1442 networks.
1443 * unixsock plugin: The new `unixsock' plugin provides an interface to
1444 communicate with the daemon while it is running. Right now the
1445 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1446 come.
1447 * perl plugin: The new `perl' plugin allows you to write extensions
1448 for collectd in the scripting-language Perl.
1449 * logfile plugin: The new `logfile' plugin writes logmessages to files
1450 or STDOUT or STDERR.
1451 * syslog plugin: The new `syslog' plugin sends logmessages to the
1452 system's syslog daemon.
1453 * entropy plugin: The new `entropy' plugin collects the amount of
1454 entropy currently being available to the system.
1455 * exec plugin: The new `exec' plugin forks child processes and reads
1456 back values provided by the forked processes.
1457 * iptables plugin: The new `iptables' plugin reads counters from
1458 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1459 plugin.
1460 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1461 to Peter Holik for contributing this plugin.
1462 * nut plugin: The new `nut' plugin connects the upsd of the `network
1463 ups tools' and reads information about the connected UPS.
1464 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1465 connections) field was added by Florent Monbillard.
1466 * collectd-nagios: The new `collectd-nagios' binary queries values
1467 from collectd, parses them and exits according to Nagios-standards.
1468 * manpages: The manpages have been improved a lot.
1470 2007-09-28, Version 3.11.7
1471 * wireless plugin: Correct the handling of cards returning signal and
1472 noise quality as percentage.
1474 2007-08-31, Version 3.11.6
1475 * processes plugin: Fix a potential segmentation fault.
1477 2007-05-29, Version 3.11.5
1478 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1479 * ntpd plugin: Fix a potential buffer overflow.
1480 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1481 were accounted as `zombies'.
1483 2007-04-10, Version 3.11.4
1484 * dns plugin: Change the order of includes to make the plugin compile
1485 under FreeBSD.
1487 2007-03-30, Version 3.11.3
1488 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1489 of the unused `COLLECT_KSTAT'.
1491 2007-02-11, Version 3.11.2
1492 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1493 NULL-pointer may have been passed to `printf' which causes a
1494 segfault with some libcs.
1496 2007-02-10, Version 3.11.1
1497 * df plugin: Some wrong defines have been fixed so the plugin works
1498 under Solaris again.
1499 * dns plugin: The usage of a struct has been fixed to work with
1500 non-GNU libcs.
1501 * processes plugin: Some missing defines have been added so the plugin
1502 compiles cleanly under FreeBSD and presumably other UNIXes.
1504 2006-12-22, Version 3.11.0
1505 * collectd: The new command line option `-P' makes it easier for
1506 distributors to change the location of PID-files.
1507 * collectd: The daemon shuts down faster now which makes it easier to
1508 write init.d-scripts for it.
1509 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1510 caused problems every now and then.
1511 * df plugin: New config options allow to ignore certain mountpoints,
1512 filesystem types or devices.
1513 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1514 and interprets it. It collects traffic as well as qtype, opcode and
1515 rcode counts.
1516 * email plugin: Sebastian Harl has contributed this plugin which
1517 counts received mails in categories (e. g. ham, spam, virus), spam
1518 score (as given by SpamAssassin) and check types.
1519 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1520 uses `mbmon' to gather information from sensors on the motherboard.
1521 * processes plugin: Collect detailed statistics for configured
1522 processes, that's process and thread count, CPU usage, resident
1523 segment size and pagefaults.
1524 * multimeter plugin: Peter Holik contributed a new plugin which
1525 queries multimeters.
1526 * sensors plugin: Lubos Stanek has put much effort into improving this
1527 plugin, including `extended naming', collection of voltage values
1528 and the possibility to ignore certain values.
1530 2006-12-21, Version 3.10.4
1531 * Max Kellermann has identified a bug in the server routine: When
1532 opening a socket fails the daemon will (re)try opening the socket in
1533 an endless loop, ultimately leading to a `EMFILE' error.
1535 2006-11-04, Version 3.10.3
1536 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1537 ntpd's reply was sent in more than one packet, the buffer size was
1538 calculated incorrectly, resulting in the reading of uninitialized or
1539 freed memory.
1541 2006-11-01, Version 3.10.2
1542 * The sample config file has been improved.
1543 * Errors in the manpages have been corrected.
1544 * The ping-plugin now adds hosts during initialization, not during
1545 startup. This speeds up startup when no network connectivity is
1546 available. Also, the hosts are being added later when the network is
1547 available.
1548 * Improved BSD-support for the df-plugin.
1549 * Fixed syntax errors in the swap-plugin for Mac OS X.
1550 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1551 plugin.
1552 * Don't disable the mysql-plugin if connecting to the database fails
1553 during initialization. Instead, try again in increasing intervals.
1555 2006-07-19, Version 3.10.1
1556 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1557 the apcups cannot be reached, unconnected sockets will pile up and
1558 eventually lead to `Too many open files' errors.
1560 2006-07-09, Version 3.10.0
1561 * The `disk' plugin has been ported to Darwin.
1562 * The `battery' plugin should work on many Apple computers now.
1563 * The `traffic' plugin can now ignore certain interfaces. Also,
1564 statistics for sent/received packets and errors have been added.
1565 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1566 to Anthony Gialluca for contributing this plugin and providing me
1567 with a test environment :)
1568 * A plugin for monitoring an NTP instance and the local clock drift
1569 has been added.
1571 2006-06-25, Version 3.9.4
1572 * The Solaris code in the `swap' plugin has been changed to reflect
1573 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1574 working this out.
1575 * The debugging system has been fixed to work with the Sun libc.
1576 * When built without librrd the variable `operating_mode' could be
1577 uninitialized. Thanks to David Elliot for reporting the bug.
1579 2006-06-01, Version 3.9.3
1580 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1581 operating systems also profit from the changes, but I wasn't able to
1582 check that.
1583 * Changed the build system to find the netinet-includes under FreeBSD
1584 and therefore successfully build the `liboping' library there.
1586 2006-05-09, Version 3.9.2
1587 * Applied a patch to the `liboping' library. Due to a bug in the
1588 sequence checking the `ping' plugin stopped working after
1589 approximately 7.6 days.
1591 2006-05-09, Version 3.8.5
1592 * Applied a patch to the `liboping' library. Due to a bug in the
1593 sequence checking the `ping' plugin stopped working after
1594 approximately 7.6 days.
1596 2006-04-21, Version 3.9.1
1597 * Build issues with Solaris and possible other architectures have been
1598 resolved.
1599 * Problems when building the `apache'-plugin without `libcurl' have
1600 been resolved.
1601 * A bug in the `ping' plugin has been fixed. Sorry folks.
1603 2006-04-02, Version 3.9.0
1604 * A plugin to monitor the Apache webserver has been added.
1605 <http://httpd.apache.org/>
1606 * A plugin to collect statistics about virtual servers using VServer.
1607 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1608 this plugin :)
1609 * A plugin for wireless LAN cards has been added. It monitors signal
1610 strength, link quality and noise ratio..
1611 * A plugin for Apple hardware sensors has been added.
1612 * An option to compile collectd with different `step' and `heartbeat'
1613 settings has been added. The size of RRAs is no longer static but
1614 calculated based on the settings for `step' and `width'.
1615 * The `ping' plugin can now be configured to use a certain TTL.
1616 * A plugin to monitor the hardware sensors of Apple computers has been
1617 added.
1618 * The plugins `cpu', `memory', `processes' and `traffic' have been
1619 ported to Mach/Darwin (Mac OS X).
1620 * The `log mode' has been contributed by Christophe Kalt. It writes
1621 the data into text files rather than RRD files.
1623 2006-04-09, Version 3.8.4
1624 * Applied patch by Vincent Stehlé which improves the disk-name
1625 resolution in the `hddtemp' plugin for Linux systems.
1627 2006-04-02, Version 3.8.3
1628 * Applied a patch by James Byers: The MySQL plugin was not working
1629 with MySQL 5.0.2 or later.
1631 2006-03-14, Version 3.8.2
1632 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1633 the GNU libc, because it points to `/etc/fstab' rather than
1634 `/etc/mtab'.
1636 2006-03-13, Version 3.8.1
1637 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1638 * Fixes in the debian `postinst' and `init.d' scripts.
1640 2006-03-09, Version 3.8.0
1641 * The `ping' plugin no longer uses `libping' but a self written
1642 library named `liboping'. With this library it's possible to ping
1643 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1645 2006-02-18, Version 3.7.2
1646 * A simple bug in the `battery' plugin has been fixed. It should now
1647 work with ACPI based batteries as well. Thanks to Sebastian for
1648 fixing this.
1649 * Fixing a bug that prevented collectd to be built without librrd.
1650 Thanks to Werner Heuser for reporting it.
1652 2006-02-04, Version 3.7.1
1653 * The new network code has been improved to build with older versions
1654 of glibc.
1655 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1656 to Tommie Gannert for this patch.
1658 2006-01-30, Version 3.7.0
1659 * The `battery' plugin has been added. It collects information about
1660 laptop batteries..
1661 * The MySQL plugin has been improved: It now writes two more RRD
1662 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1663 * The `cpufreq' plugin now reads another file since the file it did
1664 read so far causes much overhead in the kernel. Also, you need root
1665 to read the old file, but not to read the new one.
1666 * The `hddtemp' plugin can now be configured to connect to another
1667 address and/or port than localhost.
1668 * The `df' plugin now prefers `statvfs' over `statfs'.
1669 * The network code has been rewritten. collectd now supports unicast
1670 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1671 be set in the configfile.
1673 2006-01-24, Version 3.6.2
1674 * Due to a bug in the configfile handling collectd wouldn't start in
1675 client mode. This released fixes this.
1677 2006-01-20, Version 3.6.1
1678 * Due to a bug in `configure.in' all modules and the binary were
1679 linked against `libmysqlclient'. This issue is solved by this
1680 release.
1682 2006-01-17, Version 3.6.0
1683 * A config file has been added. This allows for loading only specific
1684 plugins.
1685 * A `df' plugin has been added.
1686 * A `mysql' plugin has been added.
1687 * The `ping' plugin doesn't entirely give up hope when a socket error
1688 occurred, but will back of and increase the intervals between tries.
1690 2006-01-21, Version 3.5.2
1691 * Fixed yet another bug in the signal handling.. Stupid typo..
1692 * Improved the ping plugin to not give up on socket errors (backport
1693 from 3.6.0).
1695 2005-12-18, Version 3.5.1
1696 * The PID-file is now deleted correctly when shutting down the daemon.
1697 * SIGINT and SIGTERM are now handled correctly.
1699 2005-12-16, Version 3.5.0 (Revision 326)
1700 * A bug in the `load' module under Solaris has been fixed.
1701 * The `users' module has been contributed by Sebastian Harl. It counts
1702 currently logged in users.
1703 * The CPU module now works under FreeBSD without the use of
1704 `libstatgrab', however SMP support is missing.
1705 * The default directories for the RRD files and the PID file now
1706 depend on the compile time setting of `localstatedir'.
1708 2005-11-15, Version 3.4.0 (Revision 236)
1709 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1710 from gentoo's bugzilla for writing the patch.
1711 * The build dependency for librrd has been removed. Binaries built
1712 without librrd are client-only and will multicast their value as
1713 with the `-c' argument.
1714 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1715 * The newly introduced `-f' switch prevents daemon initialization
1716 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1717 Barcellos for this patch.
1719 2005-11-04, Version 3.3.0 (Revision 216)
1720 * New modules have been added:
1721 - `serial', for monitoring traffic on the serial interfaces
1722 - `nfs', for graphing NFS procedure calls
1723 - `tape', traffic from/to tape devices
1724 * The memory.rrd now accepts more than 4Gig of memory.
1726 2005-10-26, Version 3.2.0 (Revision 200)
1727 * Support for graphing the processes has been added (thanks to Lyonel
1728 Vincent)
1729 * If reading from hddtemp fails collectd will increase the time
1730 between polls up to one day.
1731 * The init.d files have been improved.
1732 * Problems with the spec file have been fixed.
1734 2005-10-16, Version 3.1.0 (Revision 194)
1735 * Added the `setsid' syscall to the startup code.
1736 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1738 2005-09-30, Version 3.0.0 (Revision 184)
1739 * The ability to send/receive data to/from the network (think
1740 multicast) has been added.
1741 * Modules have been split up into shared libraries can be loaded at
1742 runtime. The biggest advantage is that the core program doesn't need
1743 to be linked against an external library.
1744 * A patch by George Kargiotakis has been applied: It fixes the sensors
1745 behaviour then more than one sensor is being queried.
1747 2005-09-16, Version 2.1.0 (Revision 172)
1748 * A module for swap statistics has been added.
1750 2005-09-09, Version 2.0.0 (Revision 135)
1751 * Filenames can no longer be configured at program startup. The only
1752 options as of this version are the directory and ping hosts.
1753 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1754 Soft-IRQ statistics are added to `System'.
1755 * Diskstats now collect read and write bytes, not sectors.
1756 * Ping statistics can now be collected for more than one host. There
1757 is no default any more: If no host is given no host will be pinged.
1758 * A self-written patch for libping has been applied so it builds
1759 cleanly.
1761 2005-09-01, Version 1.8.1 (Revision 123)
1762 * Much improved configure-script: libraries and features may now be
1763 disabled.
1764 * More detailed warnings/error messages when RRD update fails.
1766 2005-08-29, Version 1.8.0:
1767 * Support for collecting disk statistics under Solaris.
1769 2005-08-25, Version 1.7.0:
1770 * Support for libstatgrab[1] for load, memory usage and network
1771 traffic. CPU- and disk-usage are not (yet) supported, since
1772 libstatgrab returns insufficient information. I will contact the
1773 authors.
1774 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1775 aren't necessarily counted linear which is now handled correctly.
1776 [1]: http://www.i-scream.org/libstatgrab/
1778 2005-08-21, Version 1.6.0:
1779 * Basic support for Solaris: System load and cpu-usage can be
1780 collected under Solaris, too. Other stats will follow later.
1781 * Many fixes in the autoconf-script
1782 * Collection/Museum scripts have been added under contrib/museum
1783 * collectd may now be started in unprivileged mode, though ping
1784 statistics will not work.
1786 2005-07-17, Version 1.5.1:
1787 * Diskstats-RRDs now use major/minor for naming. Some systems have
1788 weird strings as disk-names..
1790 2005-07-17, Version 1.5:
1791 * A new module, diskstats, has been added. It collects information
1792 about the disks and partitions.
1794 2005-07-11, Version 1.4.2:
1795 * The meminfo module has been changed to work with more platforms
1796 and/or kernel versions.
1798 2005-07-10, Version 1.4.1: Correct traffic stats
1799 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1800 forgot to correct when I changed that module.
1802 2005-07-09, Version 1.4: More traffic stats
1803 * Traffic is now collected for all interfaces that can be found
1804 * Temperature-statistics are read from lm-sensors if available
1806 2005-07-08, Version 1.3: CPU stats
1807 * Collecting CPU statistics now
1809 2005-07-12, Version 1.2: Using syslog
1810 * collectd is now using the syslog facility to report errors, warnings
1811 and the like..
1812 * The default directory is now /var/db/collectd
1814 2005-07-10, Version 1.1: Minor changes
1815 * Nothing really useful to say ;)
1817 2005-07-09, Version 1.0: Initial Version
1818 * The following modules are provided:
1819 * Load average
1820 * Ping time
1821 * Traffic
1822 * Memory info
