471 * zfs_arc plugin: The new ZFS ARC plugin collects information about
472 the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
473 (ZFS). Thanks to Anthony Dewhurst for the patch.
474 * empty_counter match: The new Empty Counter match matches value
475 lists, where at least one data source is of type COUNTER and the
476 counter value of all counter data sources is zero.
478 2009-12-18, Version 4.7.5
479 * Build system, java plugin: Don't use “find -L” to search for Java
480 headers, because it's a GNU extension.
481 * Build system: Support for parallel builds has been improved. Thanks
482 Sebastian Harl and Stefan Völkel for looking into this.
483 * collectd: Print error messages to STDERR if no log plugin has been
484 loaded.
485 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
486 * network plugin: The license has been changed to LGPL 2.1.

488 * rrdcached plugin: Work-around for a bug in RRDtool 1.4rc2 has been
489 added.
490 * snmp plugin: Handling of negative values has been fixed. Strings
491 containing control characters are now interpreted as hex-strings.
492 * unixsock plugin: A memory leak in the LISTVAL command has been
493 fixed. Thanks to Ben Knight for his patch.
495 2009-10-03, Version 4.7.4
496 * Build system: Issues when building the iptables plugin have been
497 fixed.
498 * exec plugin: Clear the signal block mask before calling exec(2).
499 * perl plugin: Declare the “environ” variable. This solves build
500 issues on some platforms.
501 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
502 Andrés J. Díaz for the patch.
503 * unixsock plugin: Fix a (well hidden) race condition related to file
504 descriptor handling.
506 2009-09-13, Version 4.7.3
507 * collectd: Fix a possible but very rare invalid “free” in the caching
508 code. Thanks to Sebastian Harl for the patch.
509 * collectd: Remove old values when a cache entry is marked as missing.
510 This way the “GETVAL” command of the UnixSock plugin doesn't return
511 old, no longer valid values when this happens. Thanks to Andrés J.
512 Díaz for the patch.
513 * collectd: The “plugin_unregister_read” function has been fixed.
514 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
515 to follow redirects. Thanks to Joey Hess for reporting this bug.

518 Hess for reporting this bug.
519 * iptables plugin: Support for the new libiptc API has been added.
520 Thanks to Sebastian Harl for the patch. The build system has been
521 updated to the plugin only includes the shipped header files when it
522 is linked with the shipped library, too.
523 * java plugin: Delay creating the JVM until after the daemon has
524 forked. The JVM internally creates threads that are lost when
525 forking. This means that Java-based plugins are now configured
526 during the init-phase, i. e. later than other plugins.
527 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
528 to Alan Pevec for the patch.
529 * network plugin: Fix the handling of the “CacheFlush” option: The
530 value was assigned to a wrong variable. The initialization of the
531 gcrypt library, which is used for signing / encrypting traffic, has
532 been fixed. Thanks to Luke Heberling for the patch.
533 * powerdns plugin: Set a timeout when reading data from the datagram
534 socket. Handling of the “LocalSocket” option has been fixed. An

551 details have been added to the configuration summary. Support for
552 libtool 2.2 has been added.
553 * collectd: Two bugs with the threshold checking have been fixed. The
554 first one prevented thresholds to be checked at all, the second one
555 caused wrong behavior with the persistency option. Thanks to Andrés
556 J. Díaz for fixing these problems.
557 * collectd: Handling of the `Include' configuration option has been
558 fixed.
559 * rrdtool plugin: Make sure initialization is run only once. This
560 resolves problems under Solaris and potentially other systems.
561 Thanks to Amit Gupta for reporting this bug.
562 * java plugin: Make it possible to use dots ('.') instead of slashes
563 ('/') as the class separator. Thanks to Randy Rizun for pointing
564 this out.

574 tracking table size. Thanks to Tomasz Pala for the patch.
575 * fscache plugin: The new fscache plugin collects statistics about
576 Linux' file-system based caching framework. Thanks to Edward
577 Konetzko for the patch.
578 * gmond plugin: The new gmond plugin can receive and interpret
579 multicast traffic from Ganglia's gmond daemon.
580 * java plugin: The new java plugin exports the collectd API to Java,
581 making it possible to write extensions to collectd in Java.
582 * memcachec plugin: The new memcachec plugin queries data from a
583 memcached daemon and parses it similar to the cURL plugin. Thanks to
584 Doug MacEachern for the initial code.
585 * memcached plugin: Support for connections over UNIX domain sockets
586 has been added. Thanks to Franck Lombardi for the patch.
587 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

599 plugin must no longer be a multiple of the global interval.
600 * table plugin: The new Table plugin provides parsing for table-like
601 structured files, such as many files beneath /proc.
602 * ted plugin: The new TED plugin reads power consumption measurements
603 from “The Energy Detective” (TED). Thanks to Eric Reed for this
604 plugin.
605 * onewire plugin: The new `Interval' option allows collecting
606 information from OneWire sensors at arbitrary intervals.
607 * ping plugin: Support for collecting the drop rate and standard
608 deviation of round-trip times has been added.
609 * uptime plugin: The new uptime plugin can collect the server's
610 uptime. Thanks to Marco Chiappero for the patch.
612 2009-09-10, Version 4.6.5
613 * collectd: Remove old values when a cache entry is marked as missing.
614 This way the “GETVAL” command of the UnixSock plugin doesn't return
615 old, no longer valid values when this happens. Thanks to Andrés J.
616 Díaz for the patch.
617 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
618 to follow redirects. Thanks to Joey Hess for reporting this bug.

641 2009-06-02, Version 4.6.3
642 * Build system, various plugins: Many build fixes for FreeBSD,
643 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
644 for many fixes and providing a build system for many platforms,
645 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
646 providing an OpenBSD system.
647 * collectd: Two bugs with the threshold checking have been fixed. The
648 first one prevented thresholds to be checked at all, the second one
649 caused wrong behavior with the persistency option. Thanks to Andrés
650 J. Díaz for fixing these problems.
651 * collectd: Handling of the `Include' configuration option has been
652 fixed.
653 * battery plugin: Don't complain about a missing directory every
654 interval.

667 * filter subsystem: Allow `Chains' without default targets.
668 * liboping: A patch to comply with strict aliasing rules has been
669 added.
670 * timediff match: Fix a typo: The match was registered with a wrong
671 name which prevented this match to be used as documented. Thanks to
672 Bruno Prémont for finding this problem.
673 * bind plugin: Fix collection of the cached RR sets. The number of RR
674 sets currently in the cache was collected as a counter value, which
675 is nonsense. Thanks to Bruno Prémont for implementing this.
676 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
677 primarily BSDs, don't take it well and crash.
678 * oracle plugin: Portability to 64 bit systems has been improved.
679 * postgresql plugin: The default configuration has been improved.
680 * rrdtool plugin: Fix a possible race condition: If the network plugin
681 is brought and dispatches a value before the rrdtool plugin is
682 initialized, the daemon may crash.
684 2009-02-22, Version 4.6.1
685 * collectd: Many documentation fixes.
686 * Collectd::Unixsock: Error handling has been improved.
687 * regex match: Don't link with the PCRE library.
688 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
689 for finding and fixing most of them.
690 * ipmi plugin: Fix an off-by-one error which could cause segmentation
691 faults. Thanks to Peter Holik for his patch.
693 2009-02-16, Version 4.6.0
694 * collectd: Added the `filter chain' infrastructure, which allows the
695 user to use `matches' and `targets' to control value processing.
696 * collectd: The new `-T' command line argument allows more in-depth
697 testing of a configuration. Thanks to Doug MacEachern for the patch.
698 * collectd-nagios: The Nagios integration command has been updated to
699 use libcollectdclient. The `percentage' aggregation function has
700 been added. Thanks to Fabian Linzberger for the patch.
701 * libcollectdclient: A library which abstracts communication with the
702 unixsock plugin for clients has been added.
703 * regex match: Match values by their identifies using regular
704 expressions.
705 * timediff match: Match for values with an invalid timestamp.
706 * value match: Select values by their data sources' values.
707 * notification target: Create and dispatch a notification.
708 * replace target: Replace parts of an identifier using regular
709 expressions.
710 * set target: Set (overwrite) entire parts of an identifier.
711 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
712 statistics, allowing very detailed name server statistics. Thanks to
713 Bruno Prémont for this plugin.
714 * cpu plugin: Report `interrupt' separately when using
715 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
716 example for native OpenBSD support, has been added. Thanks to Simon
717 Kuhnle for the patch.
718 * csv plugin: Make it possible to write values to STDOUT instead of
719 files. This is meant for testing purposes mostly. The output written
720 to STDOUT is compatible with the exec plugin. Thanks to Doug
721 MacEachern for the patch.
722 * curl plugin: This new plugin can be used to read web pages and parse
723 them using the same mechanism that's used in the tail plugin.
724 * dbi plugin: This new plugin allows you to connect to a variety of
725 relational databases and use SQL to gather custom statistics from
726 it. It is similar to the already existing PostgreSQL plugin but uses
727 libdbi to communicate with the database(s).
728 * interface plugin: Use the ignorelist framework when selecting /
729 ignoring interfaces. This allows one to use regular expressions to
730 select interfaces, too.
731 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
732 Thanks to Bruno Prémont for this patch.
733 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
734 for the patch.

740 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
741 * oracle plugin: This new plugin allows you to connect to an Oracle
742 database and use SQL to gather custom statistics from it. It is
743 similar to the already existing PostgreSQL plugin.
744 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
745 have been added.
746 * perl plugin: Export the newly added plugin_write() to Perl plugins.
747 * perl plugin: Added support for `notification meta data'.
748 * perl plugin: Added support for the `filter chain' infrastructure by
749 allowing plugins to register `matches' and `targets'.
750 * postgresql plugin: The preferred configuration syntax has been
751 updated to be in line with the syntax used by the new dbi and oracle
752 plugins. The compatibility code for the old syntax is present.
753 Support for the new `Result' blocks and the interval parameter has
754 been added.
755 * processes plugin: Stacksize and virtual memory usage statistics have
756 been added. Portability fixes.
757 * rrdcached plugin: This new plugin uses the (still in development)
758 RRD accelerator daemon, rrdcached. This daemon works very similar to
759 the original rrdtool plugin of collectd, but adds some more nice
760 features.
761 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
762 added.
764 2009-05-09, Version 4.5.4
765 * Build system, various plugins: Many build fixes for FreeBSD,
766 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
767 for many fixes and providing a build system for many platforms,
768 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
769 providing an OpenBSD system.
770 * collectd: Fix a potential race condition when creating directories.
771 * battery plugin: Don't complain about a missing directory every
772 interval.
773 * dns plugin: Slight portability fixes.
774 * exec plugin: Allow executed programs to close STDERR. Thanks to
775 Thorsten von Eicken for reporting this problem.
776 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
777 Tomasz Pala for the patch.
778 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
779 the patch.
780 * rrdtool plugin: Fix a possible race condition: If the network plugin
781 is initialized and dispatches a value before the rrdtool plugin is
782 initialized, the daemon may crash.
783 * memory plugin: Fix a potential problem under Solaris.
785 2009-02-22, Version 4.5.3
786 * build system: The check for libupsclient even when `pkg-config' is
787 not available.
788 * collectd: Fix error handling in the global cache.
789 * Collectd::Unixsock: Error handling has been improved.
790 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
791 patch.

793 faults. Thanks to Peter Holik for his patch.
794 * tcpconns plugin: An endianness problem has been fixed in the *BSD
795 code. Thanks to "thated" for reporting this.
797 2009-01-02, Version 4.5.2
798 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
799 file may be in both locations, especially when the database was
800 installed in a non-standard path. Thanks to Dusty Doris for
801 reporting this.
802 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
803 Solaris, in the configure script automatically.
804 * build system, tcpconns plugin: Check for `kvm_nlist' and
805 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
806 library with similar functions to the BSD variant, but doesn't
807 provide these necessary functions.
808 * collectd.conf(5): Various fixes and clarifications.
809 * collectd: Remove a GNUism (unnamed unions), thus improving
810 portability.
811 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
812 This solves portability problems, especially for Solaris.
813 * dns plugin: Fix a portability problem with NetBSD.
814 * filecount plugin: Fix an off-by-one error. This error may cause a
815 segmentation fault.
816 * network plugin: Fix the handling of `type' in the network protocol.
817 Due to a programming mistake, only 4 or 8 bytes would be copied to a
818 much larger buffer. This caused the `type' to be transferred much
819 more often than necessary. In some cases, e. g. the `cpu' and
820 `cpufreq' plugins being used at the same time, data may be corrupted
821 in those files. Thanks to Bruno Prémont for debugging and reporting
822 this issue.
823 * processes plugin: Fix a possible segmentation fault when specifying
824 invalid configuration options.
825 * unixsock plugin: Make sure the initialization function is run only
826 once. This resolves a file descriptor leak under systems which run
827 the initialization more than once, such as Solaris.
829 2008-10-16, Version 4.5.1
830 * build system: Change `--enable-<plugin>' to abort with an error if
831 dependencies are not met. Thanks to Bruno Prémont for the patch.
832 Also, the poisoning of various string functions has been restricted
833 to debug builds.
834 * collectd: Fix a memory leak in the global value cache. With every
835 *missing* value a couple of bytes would be leaked. Another memory
836 leak in the configuration handling code has been fixed. Thanks to
837 Niraj Tolia for reporting these issues.
838 * collectd: Fix an off-by-one error in the ignorelist functionality.
839 When using regular expressions, the last character would be missing,
840 possibly matching differently from what one would expect.
841 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
842 problem.
843 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
844 Linzberger for reporting the bug.
845 * iptables plugin: Fix an off-by-one error. If a string was just one
846 character too long, it was truncated instead of reporting an error.
847 * network plugin: Fix a memory leak in the configuration handling
848 code. Thanks to Niraj Tolia for reporting this issue.
849 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
850 * postgresql plugin: Don't reopen connection during reinitialization.
851 This fixes a bug under Solaris and potentially other platforms.
852 Missing calls to `PQclear' have been added, too. This fixes memory
853 leaks. Thanks to ``Admin'' for reporting these bugs.
854 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
855 library.
856 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
857 problems with some `libc's. Thanks to Matthias Lay for reporting the
858 bug.
860 2008-09-04, Version 4.5.0
861 * collectd: Added the ability to flush certain identifiers.
862 * collectd: The concept of `notification meta data' has been
863 introduced.
864 * filecount plugin: The new filecount plugin counts the number of
865 files in a directory and its subdirectories.
866 * ipmi plugin: Sensor names have been changed to ensure unique names.
867 Notifications upon added and removed sensors can now be generated.
868 * notify_desktop plugin: This new plugin sends notifications to the
869 X desktop using the structure defined in the `Desktop Notification
870 Specification'.
871 * notify_email plugin: This new plugin sends out notifications via
872 email, using the `esmtp' library.
873 * onewire plugin: The new experimental(!) onewire plugin reads values,
874 such as temperatures, from sensors connected to the computer via the
875 onewire bus.
876 * perl plugin: Improved synchronized access to internal data structures
877 and fixed a possible dead-lock.
878 * perl plugin: Added the ability to flush certain identifiers and marked
879 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
880 plugin_flush().
881 * perl plugin: Added the ability to configure Perl plugins.
882 * postgresql plugin: The new postgresql plugin collects statistics
883 about or from a PostgreSQL database.
884 * processes plugin: The `ProcessMatch' option has been added.
885 * rrdtool plugin: Implement throttling of the `update queue' to lessen
886 IO load.
887 * tcpconns plugin: This plugin has been ported to OpenBSD.
888 * thermal plugin: The new thermal plugin collects system temperatures
889 using Linux ACPI thermal zone data.
891 2009-01-02, Version 4.4.5
892 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
893 file may be in both locations, especially when the database was
894 installed in a non-standard path. Thanks to Dusty Doris for
895 reporting this.
896 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
897 Solaris, in the configure script automatically.
898 * collectd.conf(5): Various fixes and clarifications.
899 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
900 portability problems, especially for Solaris.
901 * dns plugin: Fix a portability problem with NetBSD.
902 * network plugin: Fix the handling of `type' in the network protocol.
903 Due to a programming mistake, only 4 or 8 bytes would be copied to a
904 much larger buffer. This caused the `type' to be transferred much
905 more often than necessary. In some cases, e. g. the `cpu' and
906 `cpufreq' plugins being used at the same time, data may be corrupted
907 in those files. Thanks to Bruno Prémont for debugging and reporting
908 this issue.
909 * unixsock plugin: Make sure the initialization function is run only
910 once. This resolves a file descriptor leak under systems which run
911 the initialization more than once, such as Solaris.
913 2008-10-16, Version 4.4.4
914 * build system: Change `--enable-<plugin>' to abort with an error if
915 dependencies are not met. Thanks to Bruno Prémont for the patch.
916 Also, the poisoning of various string functions has been restricted
917 to debug builds.
918 * collectd: Fix a memory leak in the global value cache. With every
919 *missing* value a couple of bytes would be leaked. Another memory
920 leak in the configuration handling code has been fixed. Thanks to
921 Niraj Tolia for reporting these issues.
922 * collectd: Fix an off-by-one error in the ignorelist functionality.
923 When using regular expressions, the last character would be missing,
924 possibly matching differently from what one would expect.
925 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
926 problem.
927 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
928 Linzberger for reporting the bug.

930 code. Thanks to Niraj Tolia for reporting this issue.
931 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
932 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
933 problems with some `libc's. Thanks to Matthias Lay for reporting the
934 bug.
936 2008-09-01, Version 4.4.3
937 * collectd: Fix a memory leak in the threshold checking code.

941 * snmp plugin: Fix a possible memory leak.
943 2008-07-15, Version 4.4.2
944 * build system: Use pkg-config to detect the upsclient library.
945 * collectd: Try even harder to determine the endianess of the
946 architecture collectd is being built on.
947 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
948 of disks.
949 * dns plugin: Fix compilation errors with BIND versions 19991001
950 through 19991005.
951 * network plugin: Bugfix in the init routine: The init function
952 cleared a buffer regardless of its contents. This could lead to lost
953 values under Solaris.
954 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
955 * vserver plugin: Remove usage of the thread-unsafe `readdir'
956 function.

968 initialization has errors. An issue with Perl 5.10 has been fixed.
969 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
970 René Rebe and Siegmund Gorr for reporting this.
972 2008-05-06, Version 4.4.0
973 * collectd: Internal code cleanups.
974 * collectd: Added support for a `Flush' command in the unixsock and
975 exec plugins. This command can be used to force a plugin (or all) to
976 flush its values to disk.
977 * collectd: Thresholds can now be configured to apply to one data
978 source only, making it possible to configure different thresholds
979 for each data source.
980 * apache, nginx plugins: Added the possibility to disable host and/or
981 peer verification.
982 * ascent plugin: The new ascent plugin reads and parses the statistics
983 page of an Ascent server.
984 * cpu plugin: Support for the statgrab library has been added.
985 * disk plugin: The possibility to ignore certain disks or collect only
986 specific disks has been added.
987 * disk plugin: Support for the statgrab library has been added.
988 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
989 sensor values via IPMI, the intelligent platform management
990 interface.
991 * iptables plugin: The iptc library that is used by the iptables
992 plugin has been added to the distribution, because it is not
993 provided by all distributions and removed from at least one.
994 * powerdns plugin: The new powerdns plugin reads statistics from an
995 authoritative or a recursing PowerDNS name server.
996 * rrdtool plugin: The size of the files generated with the default
997 configuration has been decreased.
998 * tail plugin: The new tail plugin can be used to gather statistics by
999 continuously reading from log files.
1000 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
1001 TeamSpeak2 server and collects statistics about the number of users
1002 and number of channels.
1003 * users plugin: Support for the statgrab library has been added.
1004 * vmem plugin: The new vmem plugin collects very detailed statistics
1005 about the virtual memory subsystem of Linux.
1007 2008-08-30, Version 4.3.4
1008 * Build system: Improved detection of and linking with the statgrab
1009 library.
1010 * collectd: Portability fixes, especially to determine endianess more
1011 reliable.
1012 * Various plugins: Fix format strings.
1013 * disk plugin: A fix for giving disks under Linux 2.4 the right names
1014 again has been applied.
1015 * memcached plugin: Fix a too short timeout and a related file
1016 descriptor leak.
1017 * memory plugin: A typo in the libstatgrab code has been fixed.
1018 * network plugin: A fix in the initialization function solves problems
1019 under Solaris.
1020 * nginx plugin: A thread-unsafe function has been replaced.
1021 * vserver plugin: A thread-unsafe function has been replaced.
1022 * wireless plugin: A work-around for broken wireless drivers has been
1023 added.
1025 2008-04-22, Version 4.3.3
1026 * build system: Improved detection of several libraries, especially if
1027 they are in non-standard paths.
1028 * build system: Portability fixes: Automatically define "_REENTRANT"
1029 if the libc expects it.
1030 * collectd: Error and warning messages have been improved.
1031 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1032 using them.
1033 * apache plugin: Allocate new memory when reading a webpage instead of
1034 using a buffer of static size.
1035 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1036 the program.
1037 * hddtemp plugin: Error and warning messages have been improved.
1038 * sensors plugin: Fix sensor collection for some chip types.
1040 2008-03-29, Version 4.3.2
1041 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1042 `Persist' threshold options.
1043 * collectd: Fix handling of missing values in the global value cache.
1044 * collectd: Improved error messages when parsing the configuration.
1045 * sensors plugin: Fix temperature collection with libsensors4.
1046 * unixsock plugin: Fix mixed input and output operation on streams.
1047 * wireless plugin: Fix reading noise value.
1049 2008-03-05, Version 4.3.1
1050 * exec plugin: Set supplementary group IDs.
1051 * network plugin:
1052 + Use `memcpy' when constructing/parsing a package to avoid
1053 alignment problems on weird architectures, such as Sparc.
1054 + Translate doubles to/from the x86 byte representation to ensure
1055 cross-platform compatibility.
1056 * ping plugin: Correct the handling of the `TTL' setting.
1057 * swap plugin: Reapply a patch for Solaris.
1058 * tcpconns plugin: Portability improvements.
1060 2008-02-18, Version 4.3.0
1061 * collectd: Notifications have been added to the daemon. Notifications
1062 are status messages that may be associated with a data instance.
1063 * collectd: Threshold checking has been added to the daemon. This
1064 means that you can configure threshold values for each data
1065 instance. If this threshold is exceeded a notification will be
1066 created.
1067 * collectd: The new `FQDNLookup' option tells the daemon to use the
1068 full qualified domain name as the hostname, not just the host part
1069 es returned by `gethostname(2)'.
1070 * collectd: Support for more than one `TypesDB' file has been added.
1071 This is useful when one such file is included in a package but one
1072 wants to add custom type definitions.
1073 * collectd: The `Include' config option has been expanded to handle
1074 entire directories and shell wildcards.
1075 * collectdmon: The new `collectdmon' binary detects when collectd
1076 terminates and automatically restarts it again.
1077 * csv plugin: The CSV plugin is now able to store counter values as a
1078 rate, using the `StoreRates' configuration option.
1079 * exec plugin: Handling of notifications has been added and the
1080 ability to pass arguments to the executed programs has been added.
1081 * hddtemp plugin: The new `TranslateDevicename' option lets you
1082 disable the translation from device names to major-minor-numbers.
1083 * logfile plugin: Handling of notifications has been added.
1084 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1085 domain name lookups in this plugin.
1086 * perl plugin: Many internal changes added support for handling multiple
1087 threads making the plugin reasonably usable inside collectd. The API has
1088 been extended to support notifications and export global variables to
1089 Perl plugins; callbacks now have to be identified by name rather than a
1090 pointer to a subroutine. The plugin is no longer experimental.
1091 * uuid plugin: The new UUID plugin sets the hostname to an unique
1092 identifier for this host. This is meant for setups where each client
1093 may migrate to another physical host, possibly going through one or
1094 more name changes in the process. Thanks to Richard Jones from
1095 Red Hat's Emerging Technology group for this plugin.
1096 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1097 CPU, disk and network statistics about guest systems on the same
1098 physical server. Thanks to Richard Jones from Red Hat's Emerging
1099 Technology group for this plugin.
1101 2008-04-22, Version 4.2.7
1102 * build system: Improved detection of several libraries, especially if
1103 they are in non-standard paths.
1104 * build system: Portability fixes: Automatically define "_REENTRANT"
1105 if the libc expects it.
1106 * collectd: Error and warning messages have been improved.
1107 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1108 using them.
1109 * apache plugin: Allocate new memory when reading a webpage instead of
1110 using a buffer of static size.
1111 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1112 the program.
1113 * hddtemp plugin: Error and warning messages have been improved.
1114 * sensors plugin: Fix sensor collection for some chip types.
1116 2008-03-29, Version 4.2.6
1117 * collectd: Improved error messages when parsing the configuration.
1118 * sensors plugin: Fix temperature collection with libsensors4.
1119 * unixsock plugin: Fix mixed input and output operation on streams.
1120 * wireless plugin: Fix reading noise value.
1122 2008-03-04, Version 4.2.5
1123 * apache plugin: Improved initialization and error messages.
1124 * exec plugin: Set supplementary group IDs.
1125 * network plugin:
1126 + Create separate threads for reading from the socket and parsing
1127 and dispatching incoming packets. Versions prior to this may have
1128 problems in high-load situations, where the socket receive buffers
1129 overflows, resulting in gaps in the data.
1130 + Use `memcpy' when constructing/parsing a package to avoid
1131 alignment problems on weird architectures, such as Sparc.
1132 + Translate doubles to/from the x86 byte representation to ensure
1133 cross-platform compatibility.
1134 * ping plugin: Correct the handling of the `TTL' setting.
1135 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1136 * swap plugin: Reapply a patch for Solaris.
1137 * tcpconns plugin: Portability improvements.
1139 2008-01-21, Version 4.2.4
1140 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1141 the permission on the socket as documented in the manpage. Thanks to
1142 Evgeny Chukreev for fixing this issue.
1143 * collectd: The documentation has been improved.
1145 2007-12-28, Version 4.2.3
1146 * sensors plugin: Updated the plugin to build and work with version 3
1147 of the libsensors library.
1149 2007-12-15, Version 4.2.2
1150 * nginx plugin: Incorrect comparison of strings lead to a segfault
1151 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1152 this.
1153 * logfile plugin: The config option `Timestamp' was handled
1154 incorrectly and basically always active. Thanks to Luke Heberling
1155 for fixing this.
1157 2007-11-08, Version 4.2.1
1158 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1159 enabled on the host.
1160 * snmp plugin: Fix a memory leak.
1162 2007-10-27, Version 4.2.0
1163 * collectd: The new config option `Include' lets you include other
1164 configfiles and thus split up your config into smaller parts. This
1165 may be especially interesting for the snmp plugin to keep the data
1166 definitions separate from the host definitions.
1167 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1168 (number of connections, octets and packets for each service and
1169 destination). Thanks to Sebastian Harl for this plugin.
1170 * memcached plugin: The new `memcached' plugin connects to a memcached
1171 daemon process and collects statistics of this distributed caching
1172 system. Thanks to Antony Dovgal for contributing this plugin.
1173 * nginx plugin: The new `nginx' plugin reads the status page of an
1174 nginx daemon and saves the handled connections and requests.
1175 * perl plugin: Many changes, including the added `EnableDebugger'
1176 config option which lets you debug your Perl plugins more easily.
1177 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1178 be more thread-safe otherwise by locking calls to the library.
1179 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1180 correct the values returned by SNMP-agents. If a <data> block is
1181 defined as `table' the instance is now optional. The sequence number
1182 is used as the type-instance in this case. The new `InstancePrefix'
1183 option allows to add arbitrary prefixes to the type-instance.
1184 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1185 certain TCP connections and what state they're in. This can be used
1186 to see how many connections your FTP server has to handle or how
1187 many outgoing connections your mailserver has open.
1189 2008-01-11, Version 4.1.6
1190 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1191 the permission on the socket as documented in the manpage. Thanks to
1192 Evgeny Chukreev for fixing this issue.
1193 * collectd: The documentation has been improved.
1195 2007-12-27, Version 4.1.5
1196 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1197 memory situations.
1198 * sensors plugin: Updated the plugin to build and work with version 3
1199 of the libsensors library.
1201 2007-11-08, Version 4.1.4
1202 * Build system: Improve detection of the rrd library, especially if
1203 it's in a non-standard location.
1204 * Build system: A bug when parsing the argument for
1205 `--with-libnetsnmp' has been fixed.
1206 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1207 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1208 a deadlock or delay when shutting down the daemon.
1209 * snmp plugin: Fix a memory leak.
1211 2007-10-24, Version 4.1.3
1212 * collectd: A build issue under Solaris has been resolved by renaming
1213 data types.
1214 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1215 be more thread-safe otherwise by locking calls to the library.
1217 2007-09-28, Version 4.1.2
1218 * apcups plugin: Fix reporting of the `load percent' data.
1219 * wireless plugin: Correct the handling of cards returning signal and
1220 noise quality as percentage.
1221 * perl plugin: Fix a possible buffer overflow in get_module_name().
1222 * build system: Further improve the detection of libraries.
1223 * netlink plugin: Build issues under some older versions of the Linux
1224 includes (i. e. Debian Sarge) have been fixed.
1225 * snmp plugin: Fix a potential segfault when a host times out. Add
1226 support for the `timeticks' type.
1228 2007-09-12, Version 4.1.1
1229 * Build system: The detection of `libnetlink' has been improved.
1230 * collectd: The documentation has been fixed in numerous places.
1231 * exec plugin: Setting the group under which to run a program has been
1232 fixed.
1233 * collectd: The `sstrerror' function was improved to work correctly
1234 with the broken GNU version of `strerror_r'.
1235 * collectd: Write an error message to STDERR when loading of a plugin
1236 fails.
1237 * apcups plugin: Fix the `types' used to submit the values: They still
1238 has an `apcups_' prefix which doesn't work anymore.
1239 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1240 whatever the client thinks is `now'..
1242 2007-09-01, Version 4.1.0
1243 * Build system: The build system has been changed to automatically
1244 disable all plugins, which are missing dependencies. The dependency
1245 checking has been removed from the plugins themselves to remove
1246 redundancy.
1247 * Flexible interval: The interval of collected data is now sent along
1248 with the data itself over the network, so that the interval-settings
1249 of server and clients no longer needs to match.
1250 * netlink plugin: The new `netlink' plugin connects to the Linux
1251 kernel using a netlink socket and uses it to query information about
1252 interfaces, qdiscs and classes.
1253 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1254 to not block data collection.
1255 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1256 network devices, such as switches, routers, thermometers, rack
1257 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1258 plugin.
1259 * unixsock plugin: Added the `LISTVAL' command.
1260 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1261 of music played with xmms.
1263 2007-09-28, Version 4.0.9
1264 * apcups plugin: Fix reporting of the `load percent' data.
1265 * wireless plugin: Correct the handling of cards returning signal and
1266 noise quality as percentage.
1267 * perl plugin: Fix a possible buffer overflow in get_module_name().
1269 2007-09-12, Version 4.0.8
1270 * collectd: The `sstrerror' function was improved to work correctly
1271 with the broken GNU version of `strerror_r'.
1272 * collectd: Write an error message to STDERR when loading of a plugin
1273 fails.
1274 * apcups plugin: Fix the `types' used to submit the values: They still
1275 has an `apcups_' prefix which doesn't work anymore.
1276 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1277 whatever the client thinks is `now'..
1279 2007-08-26, Version 4.0.7
1280 * documentation: Some typos have been fixed and some information has
1281 been improved.
1282 * build system: Many fixes for detecting libraries in unusual places,
1283 such as on RedHat systems. The affected libraries are `libcurl',
1284 `libmysql', and `libupsclient'.
1285 * network plugin: Allow the `Port' option to be specified as a number
1286 (i. e. without quotes).
1287 * nut plugin: A fix allows linking the nut plugin against
1288 libupsclient, version >= 2.2.0.
1289 * processes plugin: Fix a potential segmentation fault.
1291 2007-07-30, Version 4.0.6
1292 * sensors plugin: Fix the ignorelist functionality: Only the `type
1293 instance' was used to match against the list, but the documentation
1294 told otherwise. This release fixes the code, so it complies with the
1295 documentation.
1296 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1297 configuration messages will end up in the logging facility.
1298 * conrtib/fedora: The contributed specfile for Fedora has been
1299 updated.
1301 2007-07-05, Version 4.0.5
1302 * Portability: More fixes for OpenBSD have been included.
1304 2007-06-24, Version 4.0.4
1305 * cpu plugin: Fixed the Solaris code.
1306 * dns plugin: Fixed a build issue for OpenBSD.
1307 * interface plugin: Fixed the Solaris code.
1308 * load plugin: Fixed the alternative `/proc' Linux code.
1309 * memory plugin: Fixed the Solaris code.
1310 * oconfig: Don't require `-lfl' anymore.
1312 2007-06-19, Version 4.0.3
1313 * cpu plugin: Fix the Darwin / Mac OS X code.
1314 * ping plugin: Use the return value of `getpid', not its address.
1315 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1316 initialized correctly.
1317 * configure: Added `--with-nan-emulation' to aid cross compilation.
1319 2007-06-12, Version 4.0.2
1320 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1321 they're given in numerically form.
1323 2007-06-07, Version 4.0.1
1324 * iptables plugin: A bug in the configuration routine has been fixed.
1325 Setting a comment in the configfile will no longer cause a
1326 segmentation fault.
1328 2007-06-03, Version 4.0.0
1329 * collectd: The plugin-infrastructure has been changed to allow for
1330 more types of plugins, namely `write' and `log' plugins.
1331 * collectd: The read-function has been changed to read many plugins in
1332 parallel, using threads. Thus, plugins generally need to use
1333 thread-safe functions from now on.
1334 * collectd: The '-t' command line options allows to perform syntax tests
1335 of the configuration file and exit immediately.
1336 * csv plugin: The new `csv' plugin handles output to `comma separated
1337 values'-files.
1338 * rrdtool plugin: The new `rrdtool' plugin handles output to
1339 RRD-files. Data can be cached to combine multiple updates into one
1340 write to increase IO-performance.
1341 * network plugin: The new `network' plugin handles IO via the network.
1342 It implements a different, much more extensible protocol which can
1343 combine many values in one packet, decreasing the number of UDP-
1344 packets being sent. It can read from and send to the network and
1345 with the appropriate configuration even forward packets to other
1346 networks.
1347 * unixsock plugin: The new `unixsock' plugin provides an interface to
1348 communicate with the daemon while it is running. Right now the
1349 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1350 come.
1351 * perl plugin: The new `perl' plugin allows you to write extensions
1352 for collectd in the scripting-language Perl.
1353 * logfile plugin: The new `logfile' plugin writes logmessages to files
1354 or STDOUT or STDERR.
1355 * syslog plugin: The new `syslog' plugin sends logmessages to the
1356 system's syslog daemon.
1357 * entropy plugin: The new `entropy' plugin collects the amount of
1358 entropy currently being available to the system.
1359 * exec plugin: The new `exec' plugin forks child processes and reads
1360 back values provided by the forked processes.
1361 * iptables plugin: The new `iptables' plugin reads counters from
1362 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1363 plugin.
1364 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1365 to Peter Holik for contributing this plugin.
1366 * nut plugin: The new `nut' plugin connects the upsd of the `network
1367 ups tools' and reads information about the connected UPS.
1368 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1369 connections) field was added by Florent Monbillard.
1370 * collectd-nagios: The new `collectd-nagios' binary queries values
1371 from collectd, parses them and exits according to Nagios-standards.
1372 * manpages: The manpages have been improved a lot.
1374 2007-09-28, Version 3.11.7
1375 * wireless plugin: Correct the handling of cards returning signal and
1376 noise quality as percentage.
1378 2007-08-31, Version 3.11.6
1379 * processes plugin: Fix a potential segmentation fault.
1381 2007-05-29, Version 3.11.5
1382 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1383 * ntpd plugin: Fix a potential buffer overflow.
1384 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1385 were accounted as `zombies'.
1387 2007-04-10, Version 3.11.4
1388 * dns plugin: Change the order of includes to make the plugin compile
1389 under FreeBSD.
1391 2007-03-30, Version 3.11.3
1392 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1393 of the unused `COLLECT_KSTAT'.
1395 2007-02-11, Version 3.11.2
1396 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1397 NULL-pointer may have been passed to `printf' which causes a
1398 segfault with some libcs.
1400 2007-02-10, Version 3.11.1
1401 * df plugin: Some wrong defines have been fixed so the plugin works
1402 under Solaris again.
1403 * dns plugin: The usage of a struct has been fixed to work with
1404 non-GNU libcs.
1405 * processes plugin: Some missing defines have been added so the plugin
1406 compiles cleanly under FreeBSD and presumably other UNIXes.
1408 2006-12-22, Version 3.11.0
1409 * collectd: The new command line option `-P' makes it easier for
1410 distributors to change the location of PID-files.
1411 * collectd: The daemon shuts down faster now which makes it easier to
1412 write init.d-scripts for it.
1413 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1414 caused problems every now and then.
1415 * df plugin: New config options allow to ignore certain mountpoints,
1416 filesystem types or devices.
1417 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1418 and interprets it. It collects traffic as well as qtype, opcode and
1419 rcode counts.
1420 * email plugin: Sebastian Harl has contributed this plugin which
1421 counts received mails in categories (e. g. ham, spam, virus), spam
1422 score (as given by SpamAssassin) and check types.
1423 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1424 uses `mbmon' to gather information from sensors on the motherboard.
1425 * processes plugin: Collect detailed statistics for configured
1426 processes, that's process and thread count, CPU usage, resident
1427 segment size and pagefaults.
1428 * multimeter plugin: Peter Holik contributed a new plugin which
1429 queries multimeters.
1430 * sensors plugin: Lubos Stanek has put much effort into improving this
1431 plugin, including `extended naming', collection of voltage values
1432 and the possibility to ignore certain values.
1434 2006-12-21, Version 3.10.4
1435 * Max Kellermann has identified a bug in the server routine: When
1436 opening a socket fails the daemon will (re)try opening the socket in
1437 an endless loop, ultimately leading to a `EMFILE' error.
1439 2006-11-04, Version 3.10.3
1440 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1441 ntpd's reply was sent in more than one packet, the buffer size was
1442 calculated incorrectly, resulting in the reading of uninitialized or
1443 freed memory.
1445 2006-11-01, Version 3.10.2
1446 * The sample config file has been improved.
1447 * Errors in the manpages have been corrected.
1448 * The ping-plugin now adds hosts during initialization, not during
1449 startup. This speeds up startup when no network connectivity is
1450 available. Also, the hosts are being added later when the network is
1451 available.
1452 * Improved BSD-support for the df-plugin.
1453 * Fixed syntax errors in the swap-plugin for Mac OS X.
1454 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1455 plugin.
1456 * Don't disable the mysql-plugin if connecting to the database fails
1457 during initialization. Instead, try again in increasing intervals.
1459 2006-07-19, Version 3.10.1
1460 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1461 the apcups cannot be reached, unconnected sockets will pile up and
1462 eventually lead to `Too many open files' errors.
1464 2006-07-09, Version 3.10.0
1465 * The `disk' plugin has been ported to Darwin.
1466 * The `battery' plugin should work on many Apple computers now.
1467 * The `traffic' plugin can now ignore certain interfaces. Also,
1468 statistics for sent/received packets and errors have been added.
1469 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1470 to Anthony Gialluca for contributing this plugin and providing me
1471 with a test environment :)
1472 * A plugin for monitoring an NTP instance and the local clock drift
1473 has been added.
1475 2006-06-25, Version 3.9.4
1476 * The Solaris code in the `swap' plugin has been changed to reflect
1477 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1478 working this out.
1479 * The debugging system has been fixed to work with the Sun libc.
1480 * When built without librrd the variable `operating_mode' could be
1481 uninitialized. Thanks to David Elliot for reporting the bug.
1483 2006-06-01, Version 3.9.3
1484 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1485 operating systems also profit from the changes, but I wasn't able to
1486 check that.
1487 * Changed the build system to find the netinet-includes under FreeBSD
1488 and therefore successfully build the `liboping' library there.
1490 2006-05-09, Version 3.9.2
1491 * Applied a patch to the `liboping' library. Due to a bug in the
1492 sequence checking the `ping' plugin stopped working after
1493 approximately 7.6 days.
1495 2006-05-09, Version 3.8.5
1496 * Applied a patch to the `liboping' library. Due to a bug in the
1497 sequence checking the `ping' plugin stopped working after
1498 approximately 7.6 days.
1500 2006-04-21, Version 3.9.1
1501 * Build issues with Solaris and possible other architectures have been
1502 resolved.
1503 * Problems when building the `apache'-plugin without `libcurl' have
1504 been resolved.
1505 * A bug in the `ping' plugin has been fixed. Sorry folks.
1507 2006-04-02, Version 3.9.0
1508 * A plugin to monitor the Apache webserver has been added.
1509 <http://httpd.apache.org/>
1510 * A plugin to collect statistics about virtual servers using VServer.
1511 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1512 this plugin :)
1513 * A plugin for wireless LAN cards has been added. It monitors signal
1514 strength, link quality and noise ratio..
1515 * A plugin for Apple hardware sensors has been added.
1516 * An option to compile collectd with different `step' and `heartbeat'
1517 settings has been added. The size of RRAs is no longer static but
1518 calculated based on the settings for `step' and `width'.
1519 * The `ping' plugin can now be configured to use a certain TTL.
1520 * A plugin to monitor the hardware sensors of Apple computers has been
1521 added.
1522 * The plugins `cpu', `memory', `processes' and `traffic' have been
1523 ported to Mach/Darwin (Mac OS X).
1524 * The `log mode' has been contributed by Christophe Kalt. It writes
1525 the data into text files rather than RRD files.
1527 2006-04-09, Version 3.8.4
1528 * Applied patch by Vincent Stehlé which improves the disk-name
1529 resolution in the `hddtemp' plugin for Linux systems.
1531 2006-04-02, Version 3.8.3
1532 * Applied a patch by James Byers: The MySQL plugin was not working
1533 with MySQL 5.0.2 or later.
1535 2006-03-14, Version 3.8.2
1536 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1537 the GNU libc, because it points to `/etc/fstab' rather than
1538 `/etc/mtab'.
1540 2006-03-13, Version 3.8.1
1541 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1542 * Fixes in the debian `postinst' and `init.d' scripts.
1544 2006-03-09, Version 3.8.0
1545 * The `ping' plugin no longer uses `libping' but a self written
1546 library named `liboping'. With this library it's possible to ping
1547 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1549 2006-02-18, Version 3.7.2
1550 * A simple bug in the `battery' plugin has been fixed. It should now
1551 work with ACPI based batteries as well. Thanks to Sebastian for
1552 fixing this.
1553 * Fixing a bug that prevented collectd to be built without librrd.
1554 Thanks to Werner Heuser for reporting it.
1556 2006-02-04, Version 3.7.1
1557 * The new network code has been improved to build with older versions
1558 of glibc.
1559 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1560 to Tommie Gannert for this patch.
1562 2006-01-30, Version 3.7.0
1563 * The `battery' plugin has been added. It collects information about
1564 laptop batteries..
1565 * The MySQL plugin has been improved: It now writes two more RRD
1566 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1567 * The `cpufreq' plugin now reads another file since the file it did
1568 read so far causes much overhead in the kernel. Also, you need root
1569 to read the old file, but not to read the new one.
1570 * The `hddtemp' plugin can now be configured to connect to another
1571 address and/or port than localhost.
1572 * The `df' plugin now prefers `statvfs' over `statfs'.
1573 * The network code has been rewritten. collectd now supports unicast
1574 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1575 be set in the configfile.
1577 2006-01-24, Version 3.6.2
1578 * Due to a bug in the configfile handling collectd wouldn't start in
1579 client mode. This released fixes this.
1581 2006-01-20, Version 3.6.1
1582 * Due to a bug in `configure.in' all modules and the binary were
1583 linked against `libmysqlclient'. This issue is solved by this
1584 release.
1586 2006-01-17, Version 3.6.0
1587 * A config file has been added. This allows for loading only specific
1588 plugins.
1589 * A `df' plugin has been added.
1590 * A `mysql' plugin has been added.
1591 * The `ping' plugin doesn't entirely give up hope when a socket error
1592 occurred, but will back of and increase the intervals between tries.
1594 2006-01-21, Version 3.5.2
1595 * Fixed yet another bug in the signal handling.. Stupid typo..
1596 * Improved the ping plugin to not give up on socket errors (backport
1597 from 3.6.0).
1599 2005-12-18, Version 3.5.1
1600 * The PID-file is now deleted correctly when shutting down the daemon.
1601 * SIGINT and SIGTERM are now handled correctly.
1603 2005-12-16, Version 3.5.0 (Revision 326)
1604 * A bug in the `load' module under Solaris has been fixed.
1605 * The `users' module has been contributed by Sebastian Harl. It counts
1606 currently logged in users.
1607 * The CPU module now works under FreeBSD without the use of
1608 `libstatgrab', however SMP support is missing.
1609 * The default directories for the RRD files and the PID file now
1610 depend on the compile time setting of `localstatedir'.
1612 2005-11-15, Version 3.4.0 (Revision 236)
1613 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1614 from gentoo's bugzilla for writing the patch.
1615 * The build dependency for librrd has been removed. Binaries built
1616 without librrd are client-only and will multicast their value as
1617 with the `-c' argument.
1618 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1619 * The newly introduced `-f' switch prevents daemon initialization
1620 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1621 Barcellos for this patch.
1623 2005-11-04, Version 3.3.0 (Revision 216)
1624 * New modules have been added:
1625 - `serial', for monitoring traffic on the serial interfaces
1626 - `nfs', for graphing NFS procedure calls
1627 - `tape', traffic from/to tape devices
1628 * The memory.rrd now accepts more than 4Gig of memory.
1630 2005-10-26, Version 3.2.0 (Revision 200)
1631 * Support for graphing the processes has been added (thanks to Lyonel
1632 Vincent)
1633 * If reading from hddtemp fails collectd will increase the time
1634 between polls up to one day.
1635 * The init.d files have been improved.
1636 * Problems with the spec file have been fixed.
1638 2005-10-16, Version 3.1.0 (Revision 194)
1639 * Added the `setsid' syscall to the startup code.
1640 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1642 2005-09-30, Version 3.0.0 (Revision 184)
1643 * The ability to send/receive data to/from the network (think
1644 multicast) has been added.
1645 * Modules have been split up into shared libraries can be loaded at
1646 runtime. The biggest advantage is that the core program doesn't need
1647 to be linked against an external library.
1648 * A patch by George Kargiotakis has been applied: It fixes the sensors
1649 behaviour then more than one sensor is being queried.
1651 2005-09-16, Version 2.1.0 (Revision 172)
1652 * A module for swap statistics has been added.
1654 2005-09-09, Version 2.0.0 (Revision 135)
1655 * Filenames can no longer be configured at program startup. The only
1656 options as of this version are the directory and ping hosts.
1657 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1658 Soft-IRQ statistics are added to `System'.
1659 * Diskstats now collect read and write bytes, not sectors.
1660 * Ping statistics can now be collected for more than one host. There
1661 is no default any more: If no host is given no host will be pinged.
1662 * A self-written patch for libping has been applied so it builds
1663 cleanly.
1665 2005-09-01, Version 1.8.1 (Revision 123)
1666 * Much improved configure-script: libraries and features may now be
1667 disabled.
1668 * More detailed warnings/error messages when RRD update fails.
1670 2005-08-29, Version 1.8.0:
1671 * Support for collecting disk statistics under Solaris.
1673 2005-08-25, Version 1.7.0:
1674 * Support for libstatgrab[1] for load, memory usage and network
1675 traffic. CPU- and disk-usage are not (yet) supported, since
1676 libstatgrab returns insufficient information. I will contact the
1677 authors.
1678 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1679 aren't necessarily counted linear which is now handled correctly.
1680 [1]: http://www.i-scream.org/libstatgrab/
1682 2005-08-21, Version 1.6.0:
1683 * Basic support for Solaris: System load and cpu-usage can be
1684 collected under Solaris, too. Other stats will follow later.
1685 * Many fixes in the autoconf-script
1686 * Collection/Museum scripts have been added under contrib/museum
1687 * collectd may now be started in unprivileged mode, though ping
1688 statistics will not work.
1690 2005-07-17, Version 1.5.1:
1691 * Diskstats-RRDs now use major/minor for naming. Some systems have
1692 weird strings as disk-names..
1694 2005-07-17, Version 1.5:
1695 * A new module, diskstats, has been added. It collects information
1696 about the disks and partitions.
1698 2005-07-11, Version 1.4.2:
1699 * The meminfo module has been changed to work with more platforms
1700 and/or kernel versions.
1702 2005-07-10, Version 1.4.1: Correct traffic stats
1703 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1704 forgot to correct when I changed that module.
1706 2005-07-09, Version 1.4: More traffic stats
1707 * Traffic is now collected for all interfaces that can be found
1708 * Temperature-statistics are read from lm-sensors if available
1710 2005-07-08, Version 1.3: CPU stats
1711 * Collecting CPU statistics now
1713 2005-07-12, Version 1.2: Using syslog
1714 * collectd is now using the syslog facility to report errors, warnings
1715 and the like..
1716 * The default directory is now /var/db/collectd
1718 2005-07-10, Version 1.1: Minor changes
1719 * Nothing really useful to say ;)
1721 2005-07-09, Version 1.0: Initial Version
1722 * The following modules are provided:
1723 * Load average
1724 * Ping time
1725 * Traffic
1726 * Memory info
