486 J. Díaz for fixing these problems.
487 * collectd: Handling of the `Include' configuration option has been
488 fixed.
489 * rrdtool plugin: Make sure initialization is run only once. This

510 * java plugin: The new java plugin exports the collectd API to Java,
511 making it possible to write extensions to collectd in Java.
512 * memcachec plugin: The new memcachec plugin queries data from a
513 memcached daemon and parses it similar to the cURL plugin. Thanks to
514 Doug MacEachern for the initial code.
515 * memcached plugin: Support for connections over UNIX domain sockets
516 has been added. Thanks to Franck Lombardi for the patch.

540 uptime. Thanks to Marco Chiappero for the patch.
542 2009-09-10, Version 4.6.5
543 * collectd: Remove old values when a cache entry is marked as missing.
544 This way the “GETVAL” command of the UnixSock plugin doesn't return
545 old, no longer valid values when this happens. Thanks to Andrés J.
546 Díaz for the patch.
547 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
548 to follow redirects. Thanks to Joey Hess for reporting this bug.
549 * df plugin: Check the ignorelist before stating the file system,

571 2009-06-02, Version 4.6.3
572 * Build system, various plugins: Many build fixes for FreeBSD,
573 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
574 for many fixes and providing a build system for many platforms,
575 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
576 providing an OpenBSD system.
577 * collectd: Two bugs with the threshold checking have been fixed. The
578 first one prevented thresholds to be checked at all, the second one
579 caused wrong behavior with the persistency option. Thanks to Andrés
580 J. Díaz for fixing these problems.
581 * collectd: Handling of the `Include' configuration option has been
582 fixed.

598 * liboping: A patch to comply with strict aliasing rules has been
599 added.
600 * timediff match: Fix a typo: The match was registered with a wrong
601 name which prevented this match to be used as documented. Thanks to
602 Bruno Prémont for finding this problem.
603 * bind plugin: Fix collection of the cached RR sets. The number of RR
604 sets currently in the cache was collected as a counter value, which
605 is nonsense. Thanks to Bruno Prémont for implementing this.
606 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
607 primarily BSDs, don't take it well and crash.
608 * oracle plugin: Portability to 64 bit systems has been improved.
609 * postgresql plugin: The default configuration has been improved.
610 * rrdtool plugin: Fix a possible race condition: If the network plugin
611 is brought and dispatches a value before the rrdtool plugin is
612 initialized, the daemon may crash.
614 2009-02-22, Version 4.6.1
615 * collectd: Many documentation fixes.
616 * Collectd::Unixsock: Error handling has been improved.

621 faults. Thanks to Peter Holik for his patch.
623 2009-02-16, Version 4.6.0
624 * collectd: Added the `filter chain' infrastructure, which allows the
625 user to use `matches' and `targets' to control value processing.
626 * collectd: The new `-T' command line argument allows more in-depth
627 testing of a configuration. Thanks to Doug MacEachern for the patch.
628 * collectd-nagios: The Nagios integration command has been updated to
629 use libcollectdclient. The `percentage' aggregation function has
630 been added. Thanks to Fabian Linzberger for the patch.
631 * libcollectdclient: A library which abstracts communication with the
632 unixsock plugin for clients has been added.
633 * regex match: Match values by their identifies using regular
634 expressions.
635 * timediff match: Match for values with an invalid timestamp.
636 * value match: Select values by their data sources' values.
637 * notification target: Create and dispatch a notification.
638 * replace target: Replace parts of an identifier using regular
639 expressions.
640 * set target: Set (overwrite) entire parts of an identifier.
641 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
642 statistics, allowing very detailed name server statistics. Thanks to
643 Bruno Prémont for this plugin.
644 * cpu plugin: Report `interrupt' separately when using
645 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
646 example for native OpenBSD support, has been added. Thanks to Simon
647 Kuhnle for the patch.
648 * csv plugin: Make it possible to write values to STDOUT instead of
649 files. This is meant for testing purposes mostly. The output written
650 to STDOUT is compatible with the exec plugin. Thanks to Doug
651 MacEachern for the patch.
652 * curl plugin: This new plugin can be used to read web pages and parse
653 them using the same mechanism that's used in the tail plugin.
654 * dbi plugin: This new plugin allows you to connect to a variety of
655 relational databases and use SQL to gather custom statistics from
656 it. It is similar to the already existing PostgreSQL plugin but uses
657 libdbi to communicate with the database(s).
658 * interface plugin: Use the ignorelist framework when selecting /
659 ignoring interfaces. This allows one to use regular expressions to
660 select interfaces, too.
661 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
662 Thanks to Bruno Prémont for this patch.
663 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
664 for the patch.

675 have been added.
676 * perl plugin: Export the newly added plugin_write() to Perl plugins.
677 * perl plugin: Added support for `notification meta data'.
678 * perl plugin: Added support for the `filter chain' infrastructure by
679 allowing plugins to register `matches' and `targets'.
680 * postgresql plugin: The preferred configuration syntax has been
681 updated to be in line with the syntax used by the new dbi and oracle
682 plugins. The compatibility code for the old syntax is present.
683 Support for the new `Result' blocks and the interval parameter has
684 been added.
685 * processes plugin: Stacksize and virtual memory usage statistics have
686 been added. Portability fixes.
687 * rrdcached plugin: This new plugin uses the (still in development)
688 RRD accelerator daemon, rrdcached. This daemon works very similar to
689 the original rrdtool plugin of collectd, but adds some more nice
690 features.
691 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
692 added.
694 2009-05-09, Version 4.5.4
695 * Build system, various plugins: Many build fixes for FreeBSD,
696 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
697 for many fixes and providing a build system for many platforms,
698 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
699 providing an OpenBSD system.
700 * collectd: Fix a potential race condition when creating directories.
701 * battery plugin: Don't complain about a missing directory every
702 interval.

707 Tomasz Pala for the patch.
708 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
709 the patch.
710 * rrdtool plugin: Fix a possible race condition: If the network plugin
711 is initialized and dispatches a value before the rrdtool plugin is
712 initialized, the daemon may crash.
713 * memory plugin: Fix a potential problem under Solaris.
715 2009-02-22, Version 4.5.3
716 * build system: The check for libupsclient even when `pkg-config' is
717 not available.
718 * collectd: Fix error handling in the global cache.
719 * Collectd::Unixsock: Error handling has been improved.
720 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

723 faults. Thanks to Peter Holik for his patch.
724 * tcpconns plugin: An endianness problem has been fixed in the *BSD
725 code. Thanks to "thated" for reporting this.
727 2009-01-02, Version 4.5.2
728 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
729 file may be in both locations, especially when the database was
730 installed in a non-standard path. Thanks to Dusty Doris for
731 reporting this.
732 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
733 Solaris, in the configure script automatically.
734 * build system, tcpconns plugin: Check for `kvm_nlist' and
735 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
736 library with similar functions to the BSD variant, but doesn't
737 provide these necessary functions.
738 * collectd.conf(5): Various fixes and clarifications.
739 * collectd: Remove a GNUism (unnamed unions), thus improving
740 portability.
741 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
742 This solves portability problems, especially for Solaris.
743 * dns plugin: Fix a portability problem with NetBSD.
744 * filecount plugin: Fix an off-by-one error. This error may cause a
745 segmentation fault.
746 * network plugin: Fix the handling of `type' in the network protocol.
747 Due to a programming mistake, only 4 or 8 bytes would be copied to a
748 much larger buffer. This caused the `type' to be transferred much
749 more often than necessary. In some cases, e. g. the `cpu' and
750 `cpufreq' plugins being used at the same time, data may be corrupted
751 in those files. Thanks to Bruno Prémont for debugging and reporting
752 this issue.
753 * processes plugin: Fix a possible segmentation fault when specifying
754 invalid configuration options.
755 * unixsock plugin: Make sure the initialization function is run only
756 once. This resolves a file descriptor leak under systems which run
757 the initialization more than once, such as Solaris.
759 2008-10-16, Version 4.5.1
760 * build system: Change `--enable-<plugin>' to abort with an error if
761 dependencies are not met. Thanks to Bruno Prémont for the patch.
762 Also, the poisoning of various string functions has been restricted
763 to debug builds.
764 * collectd: Fix a memory leak in the global value cache. With every
765 *missing* value a couple of bytes would be leaked. Another memory
766 leak in the configuration handling code has been fixed. Thanks to
767 Niraj Tolia for reporting these issues.
768 * collectd: Fix an off-by-one error in the ignorelist functionality.
769 When using regular expressions, the last character would be missing,
770 possibly matching differently from what one would expect.
771 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
772 problem.
773 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
774 Linzberger for reporting the bug.
775 * iptables plugin: Fix an off-by-one error. If a string was just one
776 character too long, it was truncated instead of reporting an error.
777 * network plugin: Fix a memory leak in the configuration handling
778 code. Thanks to Niraj Tolia for reporting this issue.
779 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
780 * postgresql plugin: Don't reopen connection during reinitialization.
781 This fixes a bug under Solaris and potentially other platforms.
782 Missing calls to `PQclear' have been added, too. This fixes memory
783 leaks. Thanks to ``Admin'' for reporting these bugs.
784 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
785 library.
786 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
787 problems with some `libc's. Thanks to Matthias Lay for reporting the
788 bug.
790 2008-09-04, Version 4.5.0
791 * collectd: Added the ability to flush certain identifiers.
792 * collectd: The concept of `notification meta data' has been
793 introduced.
794 * filecount plugin: The new filecount plugin counts the number of
795 files in a directory and its subdirectories.
796 * ipmi plugin: Sensor names have been changed to ensure unique names.
797 Notifications upon added and removed sensors can now be generated.
798 * notify_desktop plugin: This new plugin sends notifications to the
799 X desktop using the structure defined in the `Desktop Notification
800 Specification'.
801 * notify_email plugin: This new plugin sends out notifications via
802 email, using the `esmtp' library.
803 * onewire plugin: The new experimental(!) onewire plugin reads values,
804 such as temperatures, from sensors connected to the computer via the
805 onewire bus.
806 * perl plugin: Improved synchronized access to internal data structures
807 and fixed a possible dead-lock.
808 * perl plugin: Added the ability to flush certain identifiers and marked
809 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
810 plugin_flush().
811 * perl plugin: Added the ability to configure Perl plugins.
812 * postgresql plugin: The new postgresql plugin collects statistics
813 about or from a PostgreSQL database.
814 * processes plugin: The `ProcessMatch' option has been added.
815 * rrdtool plugin: Implement throttling of the `update queue' to lessen
816 IO load.
817 * tcpconns plugin: This plugin has been ported to OpenBSD.
818 * thermal plugin: The new thermal plugin collects system temperatures
819 using Linux ACPI thermal zone data.
821 2009-01-02, Version 4.4.5
822 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
823 file may be in both locations, especially when the database was
824 installed in a non-standard path. Thanks to Dusty Doris for
825 reporting this.
826 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
827 Solaris, in the configure script automatically.
828 * collectd.conf(5): Various fixes and clarifications.
829 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
830 portability problems, especially for Solaris.
831 * dns plugin: Fix a portability problem with NetBSD.
832 * network plugin: Fix the handling of `type' in the network protocol.
833 Due to a programming mistake, only 4 or 8 bytes would be copied to a
834 much larger buffer. This caused the `type' to be transferred much
835 more often than necessary. In some cases, e. g. the `cpu' and
836 `cpufreq' plugins being used at the same time, data may be corrupted
837 in those files. Thanks to Bruno Prémont for debugging and reporting
838 this issue.
839 * unixsock plugin: Make sure the initialization function is run only
840 once. This resolves a file descriptor leak under systems which run
841 the initialization more than once, such as Solaris.
843 2008-10-16, Version 4.4.4
844 * build system: Change `--enable-<plugin>' to abort with an error if
845 dependencies are not met. Thanks to Bruno Prémont for the patch.
846 Also, the poisoning of various string functions has been restricted
847 to debug builds.
848 * collectd: Fix a memory leak in the global value cache. With every
849 *missing* value a couple of bytes would be leaked. Another memory
850 leak in the configuration handling code has been fixed. Thanks to
851 Niraj Tolia for reporting these issues.
852 * collectd: Fix an off-by-one error in the ignorelist functionality.
853 When using regular expressions, the last character would be missing,
854 possibly matching differently from what one would expect.
855 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
856 problem.
857 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
858 Linzberger for reporting the bug.

860 code. Thanks to Niraj Tolia for reporting this issue.
861 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
862 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
863 problems with some `libc's. Thanks to Matthias Lay for reporting the
864 bug.

878 of disks.
879 * dns plugin: Fix compilation errors with BIND versions 19991001
880 through 19991005.
881 * network plugin: Bugfix in the init routine: The init function
882 cleared a buffer regardless of its contents. This could lead to lost
883 values under Solaris.
884 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
885 * vserver plugin: Remove usage of the thread-unsafe `readdir'
886 function.

894 threshold checking.
895 * collectd-nagios: Fix the protocol used to communicate with the
896 daemon.
897 * perl plugin: Fail noisily, but don't shutdown the daemon, if
898 initialization has errors. An issue with Perl 5.10 has been fixed.
899 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
900 René Rebe and Siegmund Gorr for reporting this.
902 2008-05-06, Version 4.4.0
903 * collectd: Internal code cleanups.
904 * collectd: Added support for a `Flush' command in the unixsock and
905 exec plugins. This command can be used to force a plugin (or all) to
906 flush its values to disk.
907 * collectd: Thresholds can now be configured to apply to one data
908 source only, making it possible to configure different thresholds
909 for each data source.
910 * apache, nginx plugins: Added the possibility to disable host and/or
911 peer verification.
912 * ascent plugin: The new ascent plugin reads and parses the statistics
913 page of an Ascent server.
914 * cpu plugin: Support for the statgrab library has been added.
915 * disk plugin: The possibility to ignore certain disks or collect only
916 specific disks has been added.

919 sensor values via IPMI, the intelligent platform management
920 interface.
921 * iptables plugin: The iptc library that is used by the iptables
922 plugin has been added to the distribution, because it is not
923 provided by all distributions and removed from at least one.

925 authoritative or a recursing PowerDNS name server.
926 * rrdtool plugin: The size of the files generated with the default
927 configuration has been decreased.
928 * tail plugin: The new tail plugin can be used to gather statistics by
929 continuously reading from log files.
930 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
931 TeamSpeak2 server and collects statistics about the number of users
932 and number of channels.

938 * Build system: Improved detection of and linking with the statgrab
939 library.
940 * collectd: Portability fixes, especially to determine endianess more
941 reliable.
942 * Various plugins: Fix format strings.
943 * disk plugin: A fix for giving disks under Linux 2.4 the right names
944 again has been applied.
945 * memcached plugin: Fix a too short timeout and a related file
946 descriptor leak.
947 * memory plugin: A typo in the libstatgrab code has been fixed.
948 * network plugin: A fix in the initialization function solves problems
949 under Solaris.
950 * nginx plugin: A thread-unsafe function has been replaced.
951 * vserver plugin: A thread-unsafe function has been replaced.
952 * wireless plugin: A work-around for broken wireless drivers has been
953 added.
955 2008-04-22, Version 4.3.3
956 * build system: Improved detection of several libraries, especially if
957 they are in non-standard paths.
958 * build system: Portability fixes: Automatically define "_REENTRANT"
959 if the libc expects it.
960 * collectd: Error and warning messages have been improved.
961 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
962 using them.
963 * apache plugin: Allocate new memory when reading a webpage instead of
964 using a buffer of static size.
965 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
966 the program.
967 * hddtemp plugin: Error and warning messages have been improved.
968 * sensors plugin: Fix sensor collection for some chip types.
970 2008-03-29, Version 4.3.2
971 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
972 `Persist' threshold options.
973 * collectd: Fix handling of missing values in the global value cache.
974 * collectd: Improved error messages when parsing the configuration.
975 * sensors plugin: Fix temperature collection with libsensors4.
976 * unixsock plugin: Fix mixed input and output operation on streams.
977 * wireless plugin: Fix reading noise value.
979 2008-03-05, Version 4.3.1
980 * exec plugin: Set supplementary group IDs.
981 * network plugin:
982 + Use `memcpy' when constructing/parsing a package to avoid
983 alignment problems on weird architectures, such as Sparc.
984 + Translate doubles to/from the x86 byte representation to ensure
985 cross-platform compatibility.
986 * ping plugin: Correct the handling of the `TTL' setting.
987 * swap plugin: Reapply a patch for Solaris.
988 * tcpconns plugin: Portability improvements.
990 2008-02-18, Version 4.3.0
991 * collectd: Notifications have been added to the daemon. Notifications
992 are status messages that may be associated with a data instance.
993 * collectd: Threshold checking has been added to the daemon. This
994 means that you can configure threshold values for each data
995 instance. If this threshold is exceeded a notification will be
996 created.
997 * collectd: The new `FQDNLookup' option tells the daemon to use the
998 full qualified domain name as the hostname, not just the host part
999 es returned by `gethostname(2)'.
1000 * collectd: Support for more than one `TypesDB' file has been added.
1001 This is useful when one such file is included in a package but one
1002 wants to add custom type definitions.
1003 * collectd: The `Include' config option has been expanded to handle
1004 entire directories and shell wildcards.
1005 * collectdmon: The new `collectdmon' binary detects when collectd
1006 terminates and automatically restarts it again.
1007 * csv plugin: The CSV plugin is now able to store counter values as a
1008 rate, using the `StoreRates' configuration option.
1009 * exec plugin: Handling of notifications has been added and the
1010 ability to pass arguments to the executed programs has been added.
1011 * hddtemp plugin: The new `TranslateDevicename' option lets you
1012 disable the translation from device names to major-minor-numbers.
1013 * logfile plugin: Handling of notifications has been added.
1014 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1015 domain name lookups in this plugin.
1016 * perl plugin: Many internal changes added support for handling multiple
1017 threads making the plugin reasonably usable inside collectd. The API has
1018 been extended to support notifications and export global variables to
1019 Perl plugins; callbacks now have to be identified by name rather than a
1020 pointer to a subroutine. The plugin is no longer experimental.
1021 * uuid plugin: The new UUID plugin sets the hostname to an unique
1022 identifier for this host. This is meant for setups where each client
1023 may migrate to another physical host, possibly going through one or
1024 more name changes in the process. Thanks to Richard Jones from
1025 Red Hat's Emerging Technology group for this plugin.
1026 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1027 CPU, disk and network statistics about guest systems on the same
1028 physical server. Thanks to Richard Jones from Red Hat's Emerging
1029 Technology group for this plugin.
1031 2008-04-22, Version 4.2.7
1032 * build system: Improved detection of several libraries, especially if
1033 they are in non-standard paths.
1034 * build system: Portability fixes: Automatically define "_REENTRANT"
1035 if the libc expects it.
1036 * collectd: Error and warning messages have been improved.
1037 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1038 using them.
1039 * apache plugin: Allocate new memory when reading a webpage instead of
1040 using a buffer of static size.
1041 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1042 the program.
1043 * hddtemp plugin: Error and warning messages have been improved.
1044 * sensors plugin: Fix sensor collection for some chip types.
1046 2008-03-29, Version 4.2.6
1047 * collectd: Improved error messages when parsing the configuration.
1048 * sensors plugin: Fix temperature collection with libsensors4.
1049 * unixsock plugin: Fix mixed input and output operation on streams.
1050 * wireless plugin: Fix reading noise value.
1052 2008-03-04, Version 4.2.5
1053 * apache plugin: Improved initialization and error messages.
1054 * exec plugin: Set supplementary group IDs.
1055 * network plugin:
1056 + Create separate threads for reading from the socket and parsing
1057 and dispatching incoming packets. Versions prior to this may have
1058 problems in high-load situations, where the socket receive buffers
1059 overflows, resulting in gaps in the data.
1060 + Use `memcpy' when constructing/parsing a package to avoid
1061 alignment problems on weird architectures, such as Sparc.
1062 + Translate doubles to/from the x86 byte representation to ensure
1063 cross-platform compatibility.
1064 * ping plugin: Correct the handling of the `TTL' setting.
1065 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1066 * swap plugin: Reapply a patch for Solaris.
1067 * tcpconns plugin: Portability improvements.
1069 2008-01-21, Version 4.2.4
1070 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1071 the permission on the socket as documented in the manpage. Thanks to
1072 Evgeny Chukreev for fixing this issue.
1073 * collectd: The documentation has been improved.
1075 2007-12-28, Version 4.2.3
1076 * sensors plugin: Updated the plugin to build and work with version 3
1077 of the libsensors library.
1079 2007-12-15, Version 4.2.2
1080 * nginx plugin: Incorrect comparison of strings lead to a segfault
1081 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1082 this.
1083 * logfile plugin: The config option `Timestamp' was handled
1084 incorrectly and basically always active. Thanks to Luke Heberling
1085 for fixing this.
1087 2007-11-08, Version 4.2.1
1088 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1089 enabled on the host.
1090 * snmp plugin: Fix a memory leak.
1092 2007-10-27, Version 4.2.0
1093 * collectd: The new config option `Include' lets you include other
1094 configfiles and thus split up your config into smaller parts. This
1095 may be especially interesting for the snmp plugin to keep the data
1096 definitions separate from the host definitions.
1097 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1098 (number of connections, octets and packets for each service and
1099 destination). Thanks to Sebastian Harl for this plugin.
1100 * memcached plugin: The new `memcached' plugin connects to a memcached
1101 daemon process and collects statistics of this distributed caching
1102 system. Thanks to Antony Dovgal for contributing this plugin.
1103 * nginx plugin: The new `nginx' plugin reads the status page of an
1104 nginx daemon and saves the handled connections and requests.
1105 * perl plugin: Many changes, including the added `EnableDebugger'
1106 config option which lets you debug your Perl plugins more easily.
1107 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1108 be more thread-safe otherwise by locking calls to the library.
1109 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1110 correct the values returned by SNMP-agents. If a <data> block is
1111 defined as `table' the instance is now optional. The sequence number
1112 is used as the type-instance in this case. The new `InstancePrefix'
1113 option allows to add arbitrary prefixes to the type-instance.
1114 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1115 certain TCP connections and what state they're in. This can be used
1116 to see how many connections your FTP server has to handle or how
1117 many outgoing connections your mailserver has open.
1119 2008-01-11, Version 4.1.6
1120 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1121 the permission on the socket as documented in the manpage. Thanks to
1122 Evgeny Chukreev for fixing this issue.
1123 * collectd: The documentation has been improved.
1125 2007-12-27, Version 4.1.5
1126 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1127 memory situations.
1128 * sensors plugin: Updated the plugin to build and work with version 3
1129 of the libsensors library.
1131 2007-11-08, Version 4.1.4
1132 * Build system: Improve detection of the rrd library, especially if
1133 it's in a non-standard location.
1134 * Build system: A bug when parsing the argument for
1135 `--with-libnetsnmp' has been fixed.
1136 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1137 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1138 a deadlock or delay when shutting down the daemon.
1139 * snmp plugin: Fix a memory leak.
1141 2007-10-24, Version 4.1.3
1142 * collectd: A build issue under Solaris has been resolved by renaming
1143 data types.
1144 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1145 be more thread-safe otherwise by locking calls to the library.
1147 2007-09-28, Version 4.1.2
1148 * apcups plugin: Fix reporting of the `load percent' data.
1149 * wireless plugin: Correct the handling of cards returning signal and
1150 noise quality as percentage.
1151 * perl plugin: Fix a possible buffer overflow in get_module_name().
1152 * build system: Further improve the detection of libraries.
1153 * netlink plugin: Build issues under some older versions of the Linux
1154 includes (i. e. Debian Sarge) have been fixed.
1155 * snmp plugin: Fix a potential segfault when a host times out. Add
1156 support for the `timeticks' type.
1158 2007-09-12, Version 4.1.1
1159 * Build system: The detection of `libnetlink' has been improved.
1160 * collectd: The documentation has been fixed in numerous places.
1161 * exec plugin: Setting the group under which to run a program has been
1162 fixed.
1163 * collectd: The `sstrerror' function was improved to work correctly
1164 with the broken GNU version of `strerror_r'.
1165 * collectd: Write an error message to STDERR when loading of a plugin
1166 fails.
1167 * apcups plugin: Fix the `types' used to submit the values: They still
1168 has an `apcups_' prefix which doesn't work anymore.
1169 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1170 whatever the client thinks is `now'..
1172 2007-09-01, Version 4.1.0
1173 * Build system: The build system has been changed to automatically
1174 disable all plugins, which are missing dependencies. The dependency
1175 checking has been removed from the plugins themselves to remove
1176 redundancy.
1177 * Flexible interval: The interval of collected data is now sent along
1178 with the data itself over the network, so that the interval-settings
1179 of server and clients no longer needs to match.
1180 * netlink plugin: The new `netlink' plugin connects to the Linux
1181 kernel using a netlink socket and uses it to query information about
1182 interfaces, qdiscs and classes.
1183 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1184 to not block data collection.
1185 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1186 network devices, such as switches, routers, thermometers, rack
1187 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1188 plugin.
1189 * unixsock plugin: Added the `LISTVAL' command.
1190 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1191 of music played with xmms.
1193 2007-09-28, Version 4.0.9
1194 * apcups plugin: Fix reporting of the `load percent' data.
1195 * wireless plugin: Correct the handling of cards returning signal and
1196 noise quality as percentage.
1197 * perl plugin: Fix a possible buffer overflow in get_module_name().
1199 2007-09-12, Version 4.0.8
1200 * collectd: The `sstrerror' function was improved to work correctly
1201 with the broken GNU version of `strerror_r'.
1202 * collectd: Write an error message to STDERR when loading of a plugin
1203 fails.
1204 * apcups plugin: Fix the `types' used to submit the values: They still
1205 has an `apcups_' prefix which doesn't work anymore.
1206 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1207 whatever the client thinks is `now'..
1209 2007-08-26, Version 4.0.7
1210 * documentation: Some typos have been fixed and some information has
1211 been improved.
1212 * build system: Many fixes for detecting libraries in unusual places,
1213 such as on RedHat systems. The affected libraries are `libcurl',
1214 `libmysql', and `libupsclient'.
1215 * network plugin: Allow the `Port' option to be specified as a number
1216 (i. e. without quotes).
1217 * nut plugin: A fix allows linking the nut plugin against
1218 libupsclient, version >= 2.2.0.
1219 * processes plugin: Fix a potential segmentation fault.
1221 2007-07-30, Version 4.0.6
1222 * sensors plugin: Fix the ignorelist functionality: Only the `type
1223 instance' was used to match against the list, but the documentation
1224 told otherwise. This release fixes the code, so it complies with the
1225 documentation.
1226 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1227 configuration messages will end up in the logging facility.
1228 * conrtib/fedora: The contributed specfile for Fedora has been
1229 updated.
1231 2007-07-05, Version 4.0.5
1232 * Portability: More fixes for OpenBSD have been included.
1234 2007-06-24, Version 4.0.4
1235 * cpu plugin: Fixed the Solaris code.
1236 * dns plugin: Fixed a build issue for OpenBSD.
1237 * interface plugin: Fixed the Solaris code.
1238 * load plugin: Fixed the alternative `/proc' Linux code.
1239 * memory plugin: Fixed the Solaris code.
1240 * oconfig: Don't require `-lfl' anymore.
1242 2007-06-19, Version 4.0.3
1243 * cpu plugin: Fix the Darwin / Mac OS X code.
1244 * ping plugin: Use the return value of `getpid', not its address.
1245 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1246 initialized correctly.
1247 * configure: Added `--with-nan-emulation' to aid cross compilation.
1249 2007-06-12, Version 4.0.2
1250 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1251 they're given in numerically form.
1253 2007-06-07, Version 4.0.1
1254 * iptables plugin: A bug in the configuration routine has been fixed.
1255 Setting a comment in the configfile will no longer cause a
1256 segmentation fault.
1258 2007-06-03, Version 4.0.0
1259 * collectd: The plugin-infrastructure has been changed to allow for
1260 more types of plugins, namely `write' and `log' plugins.
1261 * collectd: The read-function has been changed to read many plugins in
1262 parallel, using threads. Thus, plugins generally need to use
1263 thread-safe functions from now on.
1264 * collectd: The '-t' command line options allows to perform syntax tests
1265 of the configuration file and exit immediately.
1266 * csv plugin: The new `csv' plugin handles output to `comma separated
1267 values'-files.
1268 * rrdtool plugin: The new `rrdtool' plugin handles output to
1269 RRD-files. Data can be cached to combine multiple updates into one
1270 write to increase IO-performance.
1271 * network plugin: The new `network' plugin handles IO via the network.
1272 It implements a different, much more extensible protocol which can
1273 combine many values in one packet, decreasing the number of UDP-
1274 packets being sent. It can read from and send to the network and
1275 with the appropriate configuration even forward packets to other
1276 networks.
1277 * unixsock plugin: The new `unixsock' plugin provides an interface to
1278 communicate with the daemon while it is running. Right now the
1279 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1280 come.
1281 * perl plugin: The new `perl' plugin allows you to write extensions
1282 for collectd in the scripting-language Perl.
1283 * logfile plugin: The new `logfile' plugin writes logmessages to files
1284 or STDOUT or STDERR.
1285 * syslog plugin: The new `syslog' plugin sends logmessages to the
1286 system's syslog daemon.
1287 * entropy plugin: The new `entropy' plugin collects the amount of
1288 entropy currently being available to the system.
1289 * exec plugin: The new `exec' plugin forks child processes and reads
1290 back values provided by the forked processes.
1291 * iptables plugin: The new `iptables' plugin reads counters from
1292 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1293 plugin.
1294 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1295 to Peter Holik for contributing this plugin.
1296 * nut plugin: The new `nut' plugin connects the upsd of the `network
1297 ups tools' and reads information about the connected UPS.
1298 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1299 connections) field was added by Florent Monbillard.
1300 * collectd-nagios: The new `collectd-nagios' binary queries values
1301 from collectd, parses them and exits according to Nagios-standards.
1302 * manpages: The manpages have been improved a lot.
1304 2007-09-28, Version 3.11.7
1305 * wireless plugin: Correct the handling of cards returning signal and
1306 noise quality as percentage.
1308 2007-08-31, Version 3.11.6
1309 * processes plugin: Fix a potential segmentation fault.
1311 2007-05-29, Version 3.11.5
1312 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1313 * ntpd plugin: Fix a potential buffer overflow.
1314 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1315 were accounted as `zombies'.
1317 2007-04-10, Version 3.11.4
1318 * dns plugin: Change the order of includes to make the plugin compile
1319 under FreeBSD.
1321 2007-03-30, Version 3.11.3
1322 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1323 of the unused `COLLECT_KSTAT'.
1325 2007-02-11, Version 3.11.2
1326 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1327 NULL-pointer may have been passed to `printf' which causes a
1328 segfault with some libcs.
1330 2007-02-10, Version 3.11.1
1331 * df plugin: Some wrong defines have been fixed so the plugin works
1332 under Solaris again.
1333 * dns plugin: The usage of a struct has been fixed to work with
1334 non-GNU libcs.
1335 * processes plugin: Some missing defines have been added so the plugin
1336 compiles cleanly under FreeBSD and presumably other UNIXes.
1338 2006-12-22, Version 3.11.0
1339 * collectd: The new command line option `-P' makes it easier for
1340 distributors to change the location of PID-files.
1341 * collectd: The daemon shuts down faster now which makes it easier to
1342 write init.d-scripts for it.
1343 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1344 caused problems every now and then.
1345 * df plugin: New config options allow to ignore certain mountpoints,
1346 filesystem types or devices.
1347 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1348 and interprets it. It collects traffic as well as qtype, opcode and
1349 rcode counts.
1350 * email plugin: Sebastian Harl has contributed this plugin which
1351 counts received mails in categories (e. g. ham, spam, virus), spam
1352 score (as given by SpamAssassin) and check types.
1353 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1354 uses `mbmon' to gather information from sensors on the motherboard.
1355 * processes plugin: Collect detailed statistics for configured
1356 processes, that's process and thread count, CPU usage, resident
1357 segment size and pagefaults.
1358 * multimeter plugin: Peter Holik contributed a new plugin which
1359 queries multimeters.
1360 * sensors plugin: Lubos Stanek has put much effort into improving this
1361 plugin, including `extended naming', collection of voltage values
1362 and the possibility to ignore certain values.
1364 2006-12-21, Version 3.10.4
1365 * Max Kellermann has identified a bug in the server routine: When
1366 opening a socket fails the daemon will (re)try opening the socket in
1367 an endless loop, ultimately leading to a `EMFILE' error.
1369 2006-11-04, Version 3.10.3
1370 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1371 ntpd's reply was sent in more than one packet, the buffer size was
1372 calculated incorrectly, resulting in the reading of uninitialized or
1373 freed memory.
1375 2006-11-01, Version 3.10.2
1376 * The sample config file has been improved.
1377 * Errors in the manpages have been corrected.
1378 * The ping-plugin now adds hosts during initialization, not during
1379 startup. This speeds up startup when no network connectivity is
1380 available. Also, the hosts are being added later when the network is
1381 available.
1382 * Improved BSD-support for the df-plugin.
1383 * Fixed syntax errors in the swap-plugin for Mac OS X.
1384 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1385 plugin.
1386 * Don't disable the mysql-plugin if connecting to the database fails
1387 during initialization. Instead, try again in increasing intervals.
1389 2006-07-19, Version 3.10.1
1390 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1391 the apcups cannot be reached, unconnected sockets will pile up and
1392 eventually lead to `Too many open files' errors.
1394 2006-07-09, Version 3.10.0
1395 * The `disk' plugin has been ported to Darwin.
1396 * The `battery' plugin should work on many Apple computers now.
1397 * The `traffic' plugin can now ignore certain interfaces. Also,
1398 statistics for sent/received packets and errors have been added.
1399 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1400 to Anthony Gialluca for contributing this plugin and providing me
1401 with a test environment :)
1402 * A plugin for monitoring an NTP instance and the local clock drift
1403 has been added.
1405 2006-06-25, Version 3.9.4
1406 * The Solaris code in the `swap' plugin has been changed to reflect
1407 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1408 working this out.
1409 * The debugging system has been fixed to work with the Sun libc.
1410 * When built without librrd the variable `operating_mode' could be
1411 uninitialized. Thanks to David Elliot for reporting the bug.
1413 2006-06-01, Version 3.9.3
1414 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1415 operating systems also profit from the changes, but I wasn't able to
1416 check that.
1417 * Changed the build system to find the netinet-includes under FreeBSD
1418 and therefore successfully build the `liboping' library there.
1420 2006-05-09, Version 3.9.2
1421 * Applied a patch to the `liboping' library. Due to a bug in the
1422 sequence checking the `ping' plugin stopped working after
1423 approximately 7.6 days.
1425 2006-05-09, Version 3.8.5
1426 * Applied a patch to the `liboping' library. Due to a bug in the
1427 sequence checking the `ping' plugin stopped working after
1428 approximately 7.6 days.
1430 2006-04-21, Version 3.9.1
1431 * Build issues with Solaris and possible other architectures have been
1432 resolved.
1433 * Problems when building the `apache'-plugin without `libcurl' have
1434 been resolved.
1435 * A bug in the `ping' plugin has been fixed. Sorry folks.
1437 2006-04-02, Version 3.9.0
1438 * A plugin to monitor the Apache webserver has been added.
1439 <http://httpd.apache.org/>
1440 * A plugin to collect statistics about virtual servers using VServer.
1441 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1442 this plugin :)
1443 * A plugin for wireless LAN cards has been added. It monitors signal
1444 strength, link quality and noise ratio..
1445 * A plugin for Apple hardware sensors has been added.
1446 * An option to compile collectd with different `step' and `heartbeat'
1447 settings has been added. The size of RRAs is no longer static but
1448 calculated based on the settings for `step' and `width'.
1449 * The `ping' plugin can now be configured to use a certain TTL.
1450 * A plugin to monitor the hardware sensors of Apple computers has been
1451 added.
1452 * The plugins `cpu', `memory', `processes' and `traffic' have been
1453 ported to Mach/Darwin (Mac OS X).
1454 * The `log mode' has been contributed by Christophe Kalt. It writes
1455 the data into text files rather than RRD files.
1457 2006-04-09, Version 3.8.4
1458 * Applied patch by Vincent Stehlé which improves the disk-name
1459 resolution in the `hddtemp' plugin for Linux systems.
1461 2006-04-02, Version 3.8.3
1462 * Applied a patch by James Byers: The MySQL plugin was not working
1463 with MySQL 5.0.2 or later.
1465 2006-03-14, Version 3.8.2
1466 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1467 the GNU libc, because it points to `/etc/fstab' rather than
1468 `/etc/mtab'.
1470 2006-03-13, Version 3.8.1
1471 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1472 * Fixes in the debian `postinst' and `init.d' scripts.
1474 2006-03-09, Version 3.8.0
1475 * The `ping' plugin no longer uses `libping' but a self written
1476 library named `liboping'. With this library it's possible to ping
1477 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1479 2006-02-18, Version 3.7.2
1480 * A simple bug in the `battery' plugin has been fixed. It should now
1481 work with ACPI based batteries as well. Thanks to Sebastian for
1482 fixing this.
1483 * Fixing a bug that prevented collectd to be built without librrd.
1484 Thanks to Werner Heuser for reporting it.
1486 2006-02-04, Version 3.7.1
1487 * The new network code has been improved to build with older versions
1488 of glibc.
1489 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1490 to Tommie Gannert for this patch.
1492 2006-01-30, Version 3.7.0
1493 * The `battery' plugin has been added. It collects information about
1494 laptop batteries..
1495 * The MySQL plugin has been improved: It now writes two more RRD
1496 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1497 * The `cpufreq' plugin now reads another file since the file it did
1498 read so far causes much overhead in the kernel. Also, you need root
1499 to read the old file, but not to read the new one.
1500 * The `hddtemp' plugin can now be configured to connect to another
1501 address and/or port than localhost.
1502 * The `df' plugin now prefers `statvfs' over `statfs'.
1503 * The network code has been rewritten. collectd now supports unicast
1504 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1505 be set in the configfile.
1507 2006-01-24, Version 3.6.2
1508 * Due to a bug in the configfile handling collectd wouldn't start in
1509 client mode. This released fixes this.
1511 2006-01-20, Version 3.6.1
1512 * Due to a bug in `configure.in' all modules and the binary were
1513 linked against `libmysqlclient'. This issue is solved by this
1514 release.
1516 2006-01-17, Version 3.6.0
1517 * A config file has been added. This allows for loading only specific
1518 plugins.
1519 * A `df' plugin has been added.
1520 * A `mysql' plugin has been added.
1521 * The `ping' plugin doesn't entirely give up hope when a socket error
1522 occurred, but will back of and increase the intervals between tries.
1524 2006-01-21, Version 3.5.2
1525 * Fixed yet another bug in the signal handling.. Stupid typo..
1526 * Improved the ping plugin to not give up on socket errors (backport
1527 from 3.6.0).
1529 2005-12-18, Version 3.5.1
1530 * The PID-file is now deleted correctly when shutting down the daemon.
1531 * SIGINT and SIGTERM are now handled correctly.
1533 2005-12-16, Version 3.5.0 (Revision 326)
1534 * A bug in the `load' module under Solaris has been fixed.
1535 * The `users' module has been contributed by Sebastian Harl. It counts
1536 currently logged in users.
1537 * The CPU module now works under FreeBSD without the use of
1538 `libstatgrab', however SMP support is missing.
1539 * The default directories for the RRD files and the PID file now
1540 depend on the compile time setting of `localstatedir'.
1542 2005-11-15, Version 3.4.0 (Revision 236)
1543 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1544 from gentoo's bugzilla for writing the patch.
1545 * The build dependency for librrd has been removed. Binaries built
1546 without librrd are client-only and will multicast their value as
1547 with the `-c' argument.
1548 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1549 * The newly introduced `-f' switch prevents daemon initialization
1550 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1551 Barcellos for this patch.
1553 2005-11-04, Version 3.3.0 (Revision 216)
1554 * New modules have been added:
1555 - `serial', for monitoring traffic on the serial interfaces
1556 - `nfs', for graphing NFS procedure calls
1557 - `tape', traffic from/to tape devices
1558 * The memory.rrd now accepts more than 4Gig of memory.
1560 2005-10-26, Version 3.2.0 (Revision 200)
1561 * Support for graphing the processes has been added (thanks to Lyonel
1562 Vincent)
1563 * If reading from hddtemp fails collectd will increase the time
1564 between polls up to one day.
1565 * The init.d files have been improved.
1566 * Problems with the spec file have been fixed.
1568 2005-10-16, Version 3.1.0 (Revision 194)
1569 * Added the `setsid' syscall to the startup code.
1570 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1572 2005-09-30, Version 3.0.0 (Revision 184)
1573 * The ability to send/receive data to/from the network (think
1574 multicast) has been added.
1575 * Modules have been split up into shared libraries can be loaded at
1576 runtime. The biggest advantage is that the core program doesn't need
1577 to be linked against an external library.
1578 * A patch by George Kargiotakis has been applied: It fixes the sensors
1579 behaviour then more than one sensor is being queried.
1581 2005-09-16, Version 2.1.0 (Revision 172)
1582 * A module for swap statistics has been added.
1584 2005-09-09, Version 2.0.0 (Revision 135)
1585 * Filenames can no longer be configured at program startup. The only
1586 options as of this version are the directory and ping hosts.
1587 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1588 Soft-IRQ statistics are added to `System'.
1589 * Diskstats now collect read and write bytes, not sectors.
1590 * Ping statistics can now be collected for more than one host. There
1591 is no default any more: If no host is given no host will be pinged.
1592 * A self-written patch for libping has been applied so it builds
1593 cleanly.
1595 2005-09-01, Version 1.8.1 (Revision 123)
1596 * Much improved configure-script: libraries and features may now be
1597 disabled.
1598 * More detailed warnings/error messages when RRD update fails.
1600 2005-08-29, Version 1.8.0:
1601 * Support for collecting disk statistics under Solaris.
1603 2005-08-25, Version 1.7.0:
1604 * Support for libstatgrab[1] for load, memory usage and network
1605 traffic. CPU- and disk-usage are not (yet) supported, since
1606 libstatgrab returns insufficient information. I will contact the
1607 authors.
1608 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1609 aren't necessarily counted linear which is now handled correctly.
1610 [1]: http://www.i-scream.org/libstatgrab/
1612 2005-08-21, Version 1.6.0:
1613 * Basic support for Solaris: System load and cpu-usage can be
1614 collected under Solaris, too. Other stats will follow later.
1615 * Many fixes in the autoconf-script
1616 * Collection/Museum scripts have been added under contrib/museum
1617 * collectd may now be started in unprivileged mode, though ping
1618 statistics will not work.
1620 2005-07-17, Version 1.5.1:
1621 * Diskstats-RRDs now use major/minor for naming. Some systems have
1622 weird strings as disk-names..
1624 2005-07-17, Version 1.5:
1625 * A new module, diskstats, has been added. It collects information
1626 about the disks and partitions.
1628 2005-07-11, Version 1.4.2:
1629 * The meminfo module has been changed to work with more platforms
1630 and/or kernel versions.
1632 2005-07-10, Version 1.4.1: Correct traffic stats
1633 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1634 forgot to correct when I changed that module.
1636 2005-07-09, Version 1.4: More traffic stats
1637 * Traffic is now collected for all interfaces that can be found
1638 * Temperature-statistics are read from lm-sensors if available
1640 2005-07-08, Version 1.3: CPU stats
1641 * Collecting CPU statistics now
1643 2005-07-12, Version 1.2: Using syslog
1644 * collectd is now using the syslog facility to report errors, warnings
1645 and the like..
1646 * The default directory is now /var/db/collectd
1648 2005-07-10, Version 1.1: Minor changes
1649 * Nothing really useful to say ;)
1651 2005-07-09, Version 1.0: Initial Version
1652 * The following modules are provided:
1653 * Load average
1654 * Ping time
1655 * Traffic
1656 * Memory info
