470 2009-09-13, Version 4.7.3
471 * collectd: Fix a possible but very rare invalid “free” in the caching
472 code. Thanks to Sebastian Harl for the patch.
473 * collectd: Remove old values when a cache entry is marked as missing.
474 This way the “GETVAL” command of the UnixSock plugin doesn't return
475 old, no longer valid values when this happens. Thanks to Andrés J.
476 Díaz for the patch.
477 * collectd: The “plugin_unregister_read” function has been fixed.
478 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
479 to follow redirects. Thanks to Joey Hess for reporting this bug.
480 * df plugin: Check the ignorelist before stating the file system,
481 possibly reducing the number of stats considerably. Thanks to Joey
482 Hess for reporting this bug.
483 * iptables plugin: Support for the new libiptc API has been added.
484 Thanks to Sebastian Harl for the patch. The build system has been
485 updated to the plugin only includes the shipped header files when it
486 is linked with the shipped library, too.
487 * java plugin: Delay creating the JVM until after the daemon has
488 forked. The JVM internally creates threads that are lost when
489 forking. This means that Java-based plugins are now configured
490 during the init-phase, i. e. later than other plugins.
491 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
492 to Alan Pevec for the patch.
493 * network plugin: Fix the handling of the “CacheFlush” option: The
494 value was assigned to a wrong variable. The initialization of the
495 gcrypt library, which is used for signing / encrypting traffic, has
496 been fixed. Thanks to Luke Heberling for the patch.
497 * powerdns plugin: Set a timeout when reading data from the datagram
498 socket. Handling of the “LocalSocket” option has been fixed. An
499 incorrectly used “type” has been corrected. Thanks to Luke Heberling
500 for his patches.

510 for reporting the bug.
511 * ping plugin: Link the plugin with libm.
513 2009-06-02, Version 4.7.1
514 * Build system: Detection of Java has been improved and missing
515 details have been added to the configuration summary. Support for
516 libtool 2.2 has been added.
517 * collectd: Two bugs with the threshold checking have been fixed. The
518 first one prevented thresholds to be checked at all, the second one
519 caused wrong behavior with the persistency option. Thanks to Andrés
520 J. Díaz for fixing these problems.
521 * collectd: Handling of the `Include' configuration option has been
522 fixed.
523 * rrdtool plugin: Make sure initialization is run only once. This
524 resolves problems under Solaris and potentially other systems.
525 Thanks to Amit Gupta for reporting this bug.
526 * java plugin: Make it possible to use dots ('.') instead of slashes
527 ('/') as the class separator. Thanks to Randy Rizun for pointing
528 this out.
529 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
530 to Doug MacEachern for the patch.

538 tracking table size. Thanks to Tomasz Pala for the patch.
539 * fscache plugin: The new fscache plugin collects statistics about
540 Linux' file-system based caching framework. Thanks to Edward
541 Konetzko for the patch.
542 * gmond plugin: The new gmond plugin can receive and interpret
543 multicast traffic from Ganglia's gmond daemon.
544 * java plugin: The new java plugin exports the collectd API to Java,
545 making it possible to write extensions to collectd in Java.
546 * memcachec plugin: The new memcachec plugin queries data from a
547 memcached daemon and parses it similar to the cURL plugin. Thanks to
548 Doug MacEachern for the initial code.
549 * memcached plugin: Support for connections over UNIX domain sockets
550 has been added. Thanks to Franck Lombardi for the patch.
551 * memory plugin: Support for OpenBSD and possibly other *BSDs has been
552 added. Thanks to Simon Kuhnle for the patch.

563 plugin must no longer be a multiple of the global interval.
564 * table plugin: The new Table plugin provides parsing for table-like
565 structured files, such as many files beneath /proc.
566 * ted plugin: The new TED plugin reads power consumption measurements
567 from “The Energy Detective” (TED). Thanks to Eric Reed for this
568 plugin.
569 * onewire plugin: The new `Interval' option allows collecting
570 information from OneWire sensors at arbitrary intervals.
571 * ping plugin: Support for collecting the drop rate and standard
572 deviation of round-trip times has been added.
573 * uptime plugin: The new uptime plugin can collect the server's
574 uptime. Thanks to Marco Chiappero for the patch.
576 2009-09-10, Version 4.6.5
577 * collectd: Remove old values when a cache entry is marked as missing.
578 This way the “GETVAL” command of the UnixSock plugin doesn't return
579 old, no longer valid values when this happens. Thanks to Andrés J.
580 Díaz for the patch.
581 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
582 to follow redirects. Thanks to Joey Hess for reporting this bug.

603 for reporting the bug.
605 2009-06-02, Version 4.6.3
606 * Build system, various plugins: Many build fixes for FreeBSD,
607 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
608 for many fixes and providing a build system for many platforms,
609 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
610 providing an OpenBSD system.
611 * collectd: Two bugs with the threshold checking have been fixed. The
612 first one prevented thresholds to be checked at all, the second one
613 caused wrong behavior with the persistency option. Thanks to Andrés
614 J. Díaz for fixing these problems.
615 * collectd: Handling of the `Include' configuration option has been
616 fixed.
617 * battery plugin: Don't complain about a missing directory every
618 interval.
619 * exec plugin: Allow executed programs to close STDERR. Thanks to
620 Thorsten von Eicken for reporting this problem.
621 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
622 Tomasz Pala for the patch.

631 * filter subsystem: Allow `Chains' without default targets.
632 * liboping: A patch to comply with strict aliasing rules has been
633 added.
634 * timediff match: Fix a typo: The match was registered with a wrong
635 name which prevented this match to be used as documented. Thanks to
636 Bruno Prémont for finding this problem.
637 * bind plugin: Fix collection of the cached RR sets. The number of RR
638 sets currently in the cache was collected as a counter value, which
639 is nonsense. Thanks to Bruno Prémont for implementing this.
640 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
641 primarily BSDs, don't take it well and crash.
642 * oracle plugin: Portability to 64 bit systems has been improved.
643 * postgresql plugin: The default configuration has been improved.
644 * rrdtool plugin: Fix a possible race condition: If the network plugin
645 is brought and dispatches a value before the rrdtool plugin is
646 initialized, the daemon may crash.
648 2009-02-22, Version 4.6.1
649 * collectd: Many documentation fixes.
650 * Collectd::Unixsock: Error handling has been improved.
651 * regex match: Don't link with the PCRE library.
652 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
653 for finding and fixing most of them.
654 * ipmi plugin: Fix an off-by-one error which could cause segmentation
655 faults. Thanks to Peter Holik for his patch.
657 2009-02-16, Version 4.6.0
658 * collectd: Added the `filter chain' infrastructure, which allows the
659 user to use `matches' and `targets' to control value processing.
660 * collectd: The new `-T' command line argument allows more in-depth
661 testing of a configuration. Thanks to Doug MacEachern for the patch.
662 * collectd-nagios: The Nagios integration command has been updated to
663 use libcollectdclient. The `percentage' aggregation function has
664 been added. Thanks to Fabian Linzberger for the patch.
665 * libcollectdclient: A library which abstracts communication with the
666 unixsock plugin for clients has been added.
667 * regex match: Match values by their identifies using regular
668 expressions.
669 * timediff match: Match for values with an invalid timestamp.
670 * value match: Select values by their data sources' values.
671 * notification target: Create and dispatch a notification.
672 * replace target: Replace parts of an identifier using regular
673 expressions.
674 * set target: Set (overwrite) entire parts of an identifier.
675 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
676 statistics, allowing very detailed name server statistics. Thanks to
677 Bruno Prémont for this plugin.
678 * cpu plugin: Report `interrupt' separately when using
679 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
680 example for native OpenBSD support, has been added. Thanks to Simon
681 Kuhnle for the patch.
682 * csv plugin: Make it possible to write values to STDOUT instead of
683 files. This is meant for testing purposes mostly. The output written
684 to STDOUT is compatible with the exec plugin. Thanks to Doug
685 MacEachern for the patch.
686 * curl plugin: This new plugin can be used to read web pages and parse
687 them using the same mechanism that's used in the tail plugin.
688 * dbi plugin: This new plugin allows you to connect to a variety of
689 relational databases and use SQL to gather custom statistics from
690 it. It is similar to the already existing PostgreSQL plugin but uses
691 libdbi to communicate with the database(s).
692 * interface plugin: Use the ignorelist framework when selecting /
693 ignoring interfaces. This allows one to use regular expressions to
694 select interfaces, too.
695 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
696 Thanks to Bruno Prémont for this patch.
697 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
698 for the patch.
699 * mysql plugin: Allow connecting to a database via the UNIX domain
700 socket, too. Thanks to Mirko Buffoni for the patch.

702 code. This hopefully will help very large setups.
703 * openvpn plugin: This new plugin collects statistics provided by the
704 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
705 * oracle plugin: This new plugin allows you to connect to an Oracle
706 database and use SQL to gather custom statistics from it. It is
707 similar to the already existing PostgreSQL plugin.
708 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
709 have been added.
710 * perl plugin: Export the newly added plugin_write() to Perl plugins.
711 * perl plugin: Added support for `notification meta data'.
712 * perl plugin: Added support for the `filter chain' infrastructure by
713 allowing plugins to register `matches' and `targets'.
714 * postgresql plugin: The preferred configuration syntax has been
715 updated to be in line with the syntax used by the new dbi and oracle
716 plugins. The compatibility code for the old syntax is present.
717 Support for the new `Result' blocks and the interval parameter has
718 been added.
719 * processes plugin: Stacksize and virtual memory usage statistics have
720 been added. Portability fixes.
721 * rrdcached plugin: This new plugin uses the (still in development)
722 RRD accelerator daemon, rrdcached. This daemon works very similar to
723 the original rrdtool plugin of collectd, but adds some more nice
724 features.
725 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
726 added.
728 2009-05-09, Version 4.5.4
729 * Build system, various plugins: Many build fixes for FreeBSD,
730 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
731 for many fixes and providing a build system for many platforms,
732 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
733 providing an OpenBSD system.
734 * collectd: Fix a potential race condition when creating directories.
735 * battery plugin: Don't complain about a missing directory every
736 interval.
737 * dns plugin: Slight portability fixes.
738 * exec plugin: Allow executed programs to close STDERR. Thanks to
739 Thorsten von Eicken for reporting this problem.
740 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
741 Tomasz Pala for the patch.
742 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
743 the patch.
744 * rrdtool plugin: Fix a possible race condition: If the network plugin
745 is initialized and dispatches a value before the rrdtool plugin is
746 initialized, the daemon may crash.
747 * memory plugin: Fix a potential problem under Solaris.
749 2009-02-22, Version 4.5.3
750 * build system: The check for libupsclient even when `pkg-config' is
751 not available.
752 * collectd: Fix error handling in the global cache.
753 * Collectd::Unixsock: Error handling has been improved.
754 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

757 faults. Thanks to Peter Holik for his patch.
758 * tcpconns plugin: An endianness problem has been fixed in the *BSD
759 code. Thanks to "thated" for reporting this.
761 2009-01-02, Version 4.5.2
762 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
763 file may be in both locations, especially when the database was
764 installed in a non-standard path. Thanks to Dusty Doris for
765 reporting this.
766 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
767 Solaris, in the configure script automatically.
768 * build system, tcpconns plugin: Check for `kvm_nlist' and
769 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
770 library with similar functions to the BSD variant, but doesn't
771 provide these necessary functions.
772 * collectd.conf(5): Various fixes and clarifications.
773 * collectd: Remove a GNUism (unnamed unions), thus improving
774 portability.
775 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
776 This solves portability problems, especially for Solaris.
777 * dns plugin: Fix a portability problem with NetBSD.
778 * filecount plugin: Fix an off-by-one error. This error may cause a
779 segmentation fault.
780 * network plugin: Fix the handling of `type' in the network protocol.
781 Due to a programming mistake, only 4 or 8 bytes would be copied to a
782 much larger buffer. This caused the `type' to be transferred much
783 more often than necessary. In some cases, e. g. the `cpu' and
784 `cpufreq' plugins being used at the same time, data may be corrupted
785 in those files. Thanks to Bruno Prémont for debugging and reporting
786 this issue.
787 * processes plugin: Fix a possible segmentation fault when specifying
788 invalid configuration options.
789 * unixsock plugin: Make sure the initialization function is run only
790 once. This resolves a file descriptor leak under systems which run
791 the initialization more than once, such as Solaris.
793 2008-10-16, Version 4.5.1
794 * build system: Change `--enable-<plugin>' to abort with an error if
795 dependencies are not met. Thanks to Bruno Prémont for the patch.
796 Also, the poisoning of various string functions has been restricted
797 to debug builds.
798 * collectd: Fix a memory leak in the global value cache. With every
799 *missing* value a couple of bytes would be leaked. Another memory
800 leak in the configuration handling code has been fixed. Thanks to
801 Niraj Tolia for reporting these issues.
802 * collectd: Fix an off-by-one error in the ignorelist functionality.
803 When using regular expressions, the last character would be missing,
804 possibly matching differently from what one would expect.
805 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
806 problem.
807 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
808 Linzberger for reporting the bug.
809 * iptables plugin: Fix an off-by-one error. If a string was just one
810 character too long, it was truncated instead of reporting an error.
811 * network plugin: Fix a memory leak in the configuration handling
812 code. Thanks to Niraj Tolia for reporting this issue.
813 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
814 * postgresql plugin: Don't reopen connection during reinitialization.
815 This fixes a bug under Solaris and potentially other platforms.
816 Missing calls to `PQclear' have been added, too. This fixes memory
817 leaks. Thanks to ``Admin'' for reporting these bugs.
818 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
819 library.
820 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
821 problems with some `libc's. Thanks to Matthias Lay for reporting the
822 bug.
824 2008-09-04, Version 4.5.0
825 * collectd: Added the ability to flush certain identifiers.
826 * collectd: The concept of `notification meta data' has been
827 introduced.
828 * filecount plugin: The new filecount plugin counts the number of
829 files in a directory and its subdirectories.
830 * ipmi plugin: Sensor names have been changed to ensure unique names.
831 Notifications upon added and removed sensors can now be generated.
832 * notify_desktop plugin: This new plugin sends notifications to the
833 X desktop using the structure defined in the `Desktop Notification
834 Specification'.
835 * notify_email plugin: This new plugin sends out notifications via
836 email, using the `esmtp' library.
837 * onewire plugin: The new experimental(!) onewire plugin reads values,
838 such as temperatures, from sensors connected to the computer via the
839 onewire bus.
840 * perl plugin: Improved synchronized access to internal data structures
841 and fixed a possible dead-lock.
842 * perl plugin: Added the ability to flush certain identifiers and marked
843 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
844 plugin_flush().
845 * perl plugin: Added the ability to configure Perl plugins.
846 * postgresql plugin: The new postgresql plugin collects statistics
847 about or from a PostgreSQL database.
848 * processes plugin: The `ProcessMatch' option has been added.
849 * rrdtool plugin: Implement throttling of the `update queue' to lessen
850 IO load.
851 * tcpconns plugin: This plugin has been ported to OpenBSD.
852 * thermal plugin: The new thermal plugin collects system temperatures
853 using Linux ACPI thermal zone data.
855 2009-01-02, Version 4.4.5
856 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
857 file may be in both locations, especially when the database was
858 installed in a non-standard path. Thanks to Dusty Doris for
859 reporting this.
860 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
861 Solaris, in the configure script automatically.
862 * collectd.conf(5): Various fixes and clarifications.
863 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
864 portability problems, especially for Solaris.
865 * dns plugin: Fix a portability problem with NetBSD.
866 * network plugin: Fix the handling of `type' in the network protocol.
867 Due to a programming mistake, only 4 or 8 bytes would be copied to a
868 much larger buffer. This caused the `type' to be transferred much
869 more often than necessary. In some cases, e. g. the `cpu' and
870 `cpufreq' plugins being used at the same time, data may be corrupted
871 in those files. Thanks to Bruno Prémont for debugging and reporting
872 this issue.
873 * unixsock plugin: Make sure the initialization function is run only
874 once. This resolves a file descriptor leak under systems which run
875 the initialization more than once, such as Solaris.
877 2008-10-16, Version 4.4.4
878 * build system: Change `--enable-<plugin>' to abort with an error if
879 dependencies are not met. Thanks to Bruno Prémont for the patch.
880 Also, the poisoning of various string functions has been restricted
881 to debug builds.
882 * collectd: Fix a memory leak in the global value cache. With every
883 *missing* value a couple of bytes would be leaked. Another memory
884 leak in the configuration handling code has been fixed. Thanks to
885 Niraj Tolia for reporting these issues.
886 * collectd: Fix an off-by-one error in the ignorelist functionality.
887 When using regular expressions, the last character would be missing,
888 possibly matching differently from what one would expect.
889 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
890 problem.
891 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
892 Linzberger for reporting the bug.

894 code. Thanks to Niraj Tolia for reporting this issue.
895 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
896 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
897 problems with some `libc's. Thanks to Matthias Lay for reporting the
898 bug.
900 2008-09-01, Version 4.4.3
901 * collectd: Fix a memory leak in the threshold checking code.

912 of disks.
913 * dns plugin: Fix compilation errors with BIND versions 19991001
914 through 19991005.
915 * network plugin: Bugfix in the init routine: The init function
916 cleared a buffer regardless of its contents. This could lead to lost
917 values under Solaris.
918 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
919 * vserver plugin: Remove usage of the thread-unsafe `readdir'
920 function.

928 threshold checking.
929 * collectd-nagios: Fix the protocol used to communicate with the
930 daemon.
931 * perl plugin: Fail noisily, but don't shutdown the daemon, if
932 initialization has errors. An issue with Perl 5.10 has been fixed.
933 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
934 René Rebe and Siegmund Gorr for reporting this.
936 2008-05-06, Version 4.4.0
937 * collectd: Internal code cleanups.
938 * collectd: Added support for a `Flush' command in the unixsock and
939 exec plugins. This command can be used to force a plugin (or all) to
940 flush its values to disk.
941 * collectd: Thresholds can now be configured to apply to one data
942 source only, making it possible to configure different thresholds
943 for each data source.
944 * apache, nginx plugins: Added the possibility to disable host and/or
945 peer verification.
946 * ascent plugin: The new ascent plugin reads and parses the statistics
947 page of an Ascent server.
948 * cpu plugin: Support for the statgrab library has been added.
949 * disk plugin: The possibility to ignore certain disks or collect only
950 specific disks has been added.
951 * disk plugin: Support for the statgrab library has been added.
952 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
953 sensor values via IPMI, the intelligent platform management
954 interface.
955 * iptables plugin: The iptc library that is used by the iptables
956 plugin has been added to the distribution, because it is not
957 provided by all distributions and removed from at least one.
958 * powerdns plugin: The new powerdns plugin reads statistics from an
959 authoritative or a recursing PowerDNS name server.
960 * rrdtool plugin: The size of the files generated with the default
961 configuration has been decreased.
962 * tail plugin: The new tail plugin can be used to gather statistics by
963 continuously reading from log files.
964 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
965 TeamSpeak2 server and collects statistics about the number of users
966 and number of channels.
967 * users plugin: Support for the statgrab library has been added.
968 * vmem plugin: The new vmem plugin collects very detailed statistics
969 about the virtual memory subsystem of Linux.
971 2008-08-30, Version 4.3.4
972 * Build system: Improved detection of and linking with the statgrab
973 library.
974 * collectd: Portability fixes, especially to determine endianess more
975 reliable.
976 * Various plugins: Fix format strings.
977 * disk plugin: A fix for giving disks under Linux 2.4 the right names
978 again has been applied.
979 * memcached plugin: Fix a too short timeout and a related file
980 descriptor leak.
981 * memory plugin: A typo in the libstatgrab code has been fixed.
982 * network plugin: A fix in the initialization function solves problems
983 under Solaris.
984 * nginx plugin: A thread-unsafe function has been replaced.
985 * vserver plugin: A thread-unsafe function has been replaced.
986 * wireless plugin: A work-around for broken wireless drivers has been
987 added.
989 2008-04-22, Version 4.3.3
990 * build system: Improved detection of several libraries, especially if
991 they are in non-standard paths.
992 * build system: Portability fixes: Automatically define "_REENTRANT"
993 if the libc expects it.
994 * collectd: Error and warning messages have been improved.
995 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
996 using them.
997 * apache plugin: Allocate new memory when reading a webpage instead of
998 using a buffer of static size.
999 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1000 the program.
1001 * hddtemp plugin: Error and warning messages have been improved.
1002 * sensors plugin: Fix sensor collection for some chip types.
1004 2008-03-29, Version 4.3.2
1005 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
1006 `Persist' threshold options.
1007 * collectd: Fix handling of missing values in the global value cache.
1008 * collectd: Improved error messages when parsing the configuration.
1009 * sensors plugin: Fix temperature collection with libsensors4.
1010 * unixsock plugin: Fix mixed input and output operation on streams.
1011 * wireless plugin: Fix reading noise value.
1013 2008-03-05, Version 4.3.1
1014 * exec plugin: Set supplementary group IDs.
1015 * network plugin:
1016 + Use `memcpy' when constructing/parsing a package to avoid
1017 alignment problems on weird architectures, such as Sparc.
1018 + Translate doubles to/from the x86 byte representation to ensure
1019 cross-platform compatibility.
1020 * ping plugin: Correct the handling of the `TTL' setting.
1021 * swap plugin: Reapply a patch for Solaris.
1022 * tcpconns plugin: Portability improvements.
1024 2008-02-18, Version 4.3.0
1025 * collectd: Notifications have been added to the daemon. Notifications
1026 are status messages that may be associated with a data instance.
1027 * collectd: Threshold checking has been added to the daemon. This
1028 means that you can configure threshold values for each data
1029 instance. If this threshold is exceeded a notification will be
1030 created.
1031 * collectd: The new `FQDNLookup' option tells the daemon to use the
1032 full qualified domain name as the hostname, not just the host part
1033 es returned by `gethostname(2)'.
1034 * collectd: Support for more than one `TypesDB' file has been added.
1035 This is useful when one such file is included in a package but one
1036 wants to add custom type definitions.
1037 * collectd: The `Include' config option has been expanded to handle
1038 entire directories and shell wildcards.
1039 * collectdmon: The new `collectdmon' binary detects when collectd
1040 terminates and automatically restarts it again.
1041 * csv plugin: The CSV plugin is now able to store counter values as a
1042 rate, using the `StoreRates' configuration option.
1043 * exec plugin: Handling of notifications has been added and the
1044 ability to pass arguments to the executed programs has been added.
1045 * hddtemp plugin: The new `TranslateDevicename' option lets you
1046 disable the translation from device names to major-minor-numbers.
1047 * logfile plugin: Handling of notifications has been added.
1048 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1049 domain name lookups in this plugin.
1050 * perl plugin: Many internal changes added support for handling multiple
1051 threads making the plugin reasonably usable inside collectd. The API has
1052 been extended to support notifications and export global variables to
1053 Perl plugins; callbacks now have to be identified by name rather than a
1054 pointer to a subroutine. The plugin is no longer experimental.
1055 * uuid plugin: The new UUID plugin sets the hostname to an unique
1056 identifier for this host. This is meant for setups where each client
1057 may migrate to another physical host, possibly going through one or
1058 more name changes in the process. Thanks to Richard Jones from
1059 Red Hat's Emerging Technology group for this plugin.
1060 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1061 CPU, disk and network statistics about guest systems on the same
1062 physical server. Thanks to Richard Jones from Red Hat's Emerging
1063 Technology group for this plugin.
1065 2008-04-22, Version 4.2.7
1066 * build system: Improved detection of several libraries, especially if
1067 they are in non-standard paths.
1068 * build system: Portability fixes: Automatically define "_REENTRANT"
1069 if the libc expects it.
1070 * collectd: Error and warning messages have been improved.
1071 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1072 using them.
1073 * apache plugin: Allocate new memory when reading a webpage instead of
1074 using a buffer of static size.
1075 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1076 the program.
1077 * hddtemp plugin: Error and warning messages have been improved.
1078 * sensors plugin: Fix sensor collection for some chip types.
1080 2008-03-29, Version 4.2.6
1081 * collectd: Improved error messages when parsing the configuration.
1082 * sensors plugin: Fix temperature collection with libsensors4.
1083 * unixsock plugin: Fix mixed input and output operation on streams.
1084 * wireless plugin: Fix reading noise value.
1086 2008-03-04, Version 4.2.5
1087 * apache plugin: Improved initialization and error messages.
1088 * exec plugin: Set supplementary group IDs.
1089 * network plugin:
1090 + Create separate threads for reading from the socket and parsing
1091 and dispatching incoming packets. Versions prior to this may have
1092 problems in high-load situations, where the socket receive buffers
1093 overflows, resulting in gaps in the data.
1094 + Use `memcpy' when constructing/parsing a package to avoid
1095 alignment problems on weird architectures, such as Sparc.
1096 + Translate doubles to/from the x86 byte representation to ensure
1097 cross-platform compatibility.
1098 * ping plugin: Correct the handling of the `TTL' setting.
1099 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1100 * swap plugin: Reapply a patch for Solaris.
1101 * tcpconns plugin: Portability improvements.
1103 2008-01-21, Version 4.2.4
1104 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1105 the permission on the socket as documented in the manpage. Thanks to
1106 Evgeny Chukreev for fixing this issue.
1107 * collectd: The documentation has been improved.
1109 2007-12-28, Version 4.2.3
1110 * sensors plugin: Updated the plugin to build and work with version 3
1111 of the libsensors library.
1113 2007-12-15, Version 4.2.2
1114 * nginx plugin: Incorrect comparison of strings lead to a segfault
1115 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1116 this.
1117 * logfile plugin: The config option `Timestamp' was handled
1118 incorrectly and basically always active. Thanks to Luke Heberling
1119 for fixing this.
1121 2007-11-08, Version 4.2.1
1122 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1123 enabled on the host.
1124 * snmp plugin: Fix a memory leak.
1126 2007-10-27, Version 4.2.0
1127 * collectd: The new config option `Include' lets you include other
1128 configfiles and thus split up your config into smaller parts. This
1129 may be especially interesting for the snmp plugin to keep the data
1130 definitions separate from the host definitions.
1131 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1132 (number of connections, octets and packets for each service and
1133 destination). Thanks to Sebastian Harl for this plugin.
1134 * memcached plugin: The new `memcached' plugin connects to a memcached
1135 daemon process and collects statistics of this distributed caching
1136 system. Thanks to Antony Dovgal for contributing this plugin.
1137 * nginx plugin: The new `nginx' plugin reads the status page of an
1138 nginx daemon and saves the handled connections and requests.
1139 * perl plugin: Many changes, including the added `EnableDebugger'
1140 config option which lets you debug your Perl plugins more easily.
1141 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1142 be more thread-safe otherwise by locking calls to the library.
1143 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1144 correct the values returned by SNMP-agents. If a <data> block is
1145 defined as `table' the instance is now optional. The sequence number
1146 is used as the type-instance in this case. The new `InstancePrefix'
1147 option allows to add arbitrary prefixes to the type-instance.
1148 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1149 certain TCP connections and what state they're in. This can be used
1150 to see how many connections your FTP server has to handle or how
1151 many outgoing connections your mailserver has open.
1153 2008-01-11, Version 4.1.6
1154 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1155 the permission on the socket as documented in the manpage. Thanks to
1156 Evgeny Chukreev for fixing this issue.
1157 * collectd: The documentation has been improved.
1159 2007-12-27, Version 4.1.5
1160 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1161 memory situations.
1162 * sensors plugin: Updated the plugin to build and work with version 3
1163 of the libsensors library.
1165 2007-11-08, Version 4.1.4
1166 * Build system: Improve detection of the rrd library, especially if
1167 it's in a non-standard location.
1168 * Build system: A bug when parsing the argument for
1169 `--with-libnetsnmp' has been fixed.
1170 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1171 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1172 a deadlock or delay when shutting down the daemon.
1173 * snmp plugin: Fix a memory leak.
1175 2007-10-24, Version 4.1.3
1176 * collectd: A build issue under Solaris has been resolved by renaming
1177 data types.
1178 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1179 be more thread-safe otherwise by locking calls to the library.
1181 2007-09-28, Version 4.1.2
1182 * apcups plugin: Fix reporting of the `load percent' data.
1183 * wireless plugin: Correct the handling of cards returning signal and
1184 noise quality as percentage.
1185 * perl plugin: Fix a possible buffer overflow in get_module_name().
1186 * build system: Further improve the detection of libraries.
1187 * netlink plugin: Build issues under some older versions of the Linux
1188 includes (i. e. Debian Sarge) have been fixed.
1189 * snmp plugin: Fix a potential segfault when a host times out. Add
1190 support for the `timeticks' type.
1192 2007-09-12, Version 4.1.1
1193 * Build system: The detection of `libnetlink' has been improved.
1194 * collectd: The documentation has been fixed in numerous places.
1195 * exec plugin: Setting the group under which to run a program has been
1196 fixed.
1197 * collectd: The `sstrerror' function was improved to work correctly
1198 with the broken GNU version of `strerror_r'.
1199 * collectd: Write an error message to STDERR when loading of a plugin
1200 fails.
1201 * apcups plugin: Fix the `types' used to submit the values: They still
1202 has an `apcups_' prefix which doesn't work anymore.
1203 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1204 whatever the client thinks is `now'..
1206 2007-09-01, Version 4.1.0
1207 * Build system: The build system has been changed to automatically
1208 disable all plugins, which are missing dependencies. The dependency
1209 checking has been removed from the plugins themselves to remove
1210 redundancy.
1211 * Flexible interval: The interval of collected data is now sent along
1212 with the data itself over the network, so that the interval-settings
1213 of server and clients no longer needs to match.
1214 * netlink plugin: The new `netlink' plugin connects to the Linux
1215 kernel using a netlink socket and uses it to query information about
1216 interfaces, qdiscs and classes.
1217 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1218 to not block data collection.
1219 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1220 network devices, such as switches, routers, thermometers, rack
1221 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1222 plugin.
1223 * unixsock plugin: Added the `LISTVAL' command.
1224 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1225 of music played with xmms.
1227 2007-09-28, Version 4.0.9
1228 * apcups plugin: Fix reporting of the `load percent' data.
1229 * wireless plugin: Correct the handling of cards returning signal and
1230 noise quality as percentage.
1231 * perl plugin: Fix a possible buffer overflow in get_module_name().
1233 2007-09-12, Version 4.0.8
1234 * collectd: The `sstrerror' function was improved to work correctly
1235 with the broken GNU version of `strerror_r'.
1236 * collectd: Write an error message to STDERR when loading of a plugin
1237 fails.
1238 * apcups plugin: Fix the `types' used to submit the values: They still
1239 has an `apcups_' prefix which doesn't work anymore.
1240 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1241 whatever the client thinks is `now'..
1243 2007-08-26, Version 4.0.7
1244 * documentation: Some typos have been fixed and some information has
1245 been improved.
1246 * build system: Many fixes for detecting libraries in unusual places,
1247 such as on RedHat systems. The affected libraries are `libcurl',
1248 `libmysql', and `libupsclient'.
1249 * network plugin: Allow the `Port' option to be specified as a number
1250 (i. e. without quotes).
1251 * nut plugin: A fix allows linking the nut plugin against
1252 libupsclient, version >= 2.2.0.
1253 * processes plugin: Fix a potential segmentation fault.
1255 2007-07-30, Version 4.0.6
1256 * sensors plugin: Fix the ignorelist functionality: Only the `type
1257 instance' was used to match against the list, but the documentation
1258 told otherwise. This release fixes the code, so it complies with the
1259 documentation.
1260 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1261 configuration messages will end up in the logging facility.
1262 * conrtib/fedora: The contributed specfile for Fedora has been
1263 updated.
1265 2007-07-05, Version 4.0.5
1266 * Portability: More fixes for OpenBSD have been included.
1268 2007-06-24, Version 4.0.4
1269 * cpu plugin: Fixed the Solaris code.
1270 * dns plugin: Fixed a build issue for OpenBSD.
1271 * interface plugin: Fixed the Solaris code.
1272 * load plugin: Fixed the alternative `/proc' Linux code.
1273 * memory plugin: Fixed the Solaris code.
1274 * oconfig: Don't require `-lfl' anymore.
1276 2007-06-19, Version 4.0.3
1277 * cpu plugin: Fix the Darwin / Mac OS X code.
1278 * ping plugin: Use the return value of `getpid', not its address.
1279 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1280 initialized correctly.
1281 * configure: Added `--with-nan-emulation' to aid cross compilation.
1283 2007-06-12, Version 4.0.2
1284 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1285 they're given in numerically form.
1287 2007-06-07, Version 4.0.1
1288 * iptables plugin: A bug in the configuration routine has been fixed.
1289 Setting a comment in the configfile will no longer cause a
1290 segmentation fault.
1292 2007-06-03, Version 4.0.0
1293 * collectd: The plugin-infrastructure has been changed to allow for
1294 more types of plugins, namely `write' and `log' plugins.
1295 * collectd: The read-function has been changed to read many plugins in
1296 parallel, using threads. Thus, plugins generally need to use
1297 thread-safe functions from now on.
1298 * collectd: The '-t' command line options allows to perform syntax tests
1299 of the configuration file and exit immediately.
1300 * csv plugin: The new `csv' plugin handles output to `comma separated
1301 values'-files.
1302 * rrdtool plugin: The new `rrdtool' plugin handles output to
1303 RRD-files. Data can be cached to combine multiple updates into one
1304 write to increase IO-performance.
1305 * network plugin: The new `network' plugin handles IO via the network.
1306 It implements a different, much more extensible protocol which can
1307 combine many values in one packet, decreasing the number of UDP-
1308 packets being sent. It can read from and send to the network and
1309 with the appropriate configuration even forward packets to other
1310 networks.
1311 * unixsock plugin: The new `unixsock' plugin provides an interface to
1312 communicate with the daemon while it is running. Right now the
1313 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1314 come.
1315 * perl plugin: The new `perl' plugin allows you to write extensions
1316 for collectd in the scripting-language Perl.
1317 * logfile plugin: The new `logfile' plugin writes logmessages to files
1318 or STDOUT or STDERR.
1319 * syslog plugin: The new `syslog' plugin sends logmessages to the
1320 system's syslog daemon.
1321 * entropy plugin: The new `entropy' plugin collects the amount of
1322 entropy currently being available to the system.
1323 * exec plugin: The new `exec' plugin forks child processes and reads
1324 back values provided by the forked processes.
1325 * iptables plugin: The new `iptables' plugin reads counters from
1326 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1327 plugin.
1328 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1329 to Peter Holik for contributing this plugin.
1330 * nut plugin: The new `nut' plugin connects the upsd of the `network
1331 ups tools' and reads information about the connected UPS.
1332 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1333 connections) field was added by Florent Monbillard.
1334 * collectd-nagios: The new `collectd-nagios' binary queries values
1335 from collectd, parses them and exits according to Nagios-standards.
1336 * manpages: The manpages have been improved a lot.
1338 2007-09-28, Version 3.11.7
1339 * wireless plugin: Correct the handling of cards returning signal and
1340 noise quality as percentage.
1342 2007-08-31, Version 3.11.6
1343 * processes plugin: Fix a potential segmentation fault.
1345 2007-05-29, Version 3.11.5
1346 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1347 * ntpd plugin: Fix a potential buffer overflow.
1348 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1349 were accounted as `zombies'.
1351 2007-04-10, Version 3.11.4
1352 * dns plugin: Change the order of includes to make the plugin compile
1353 under FreeBSD.
1355 2007-03-30, Version 3.11.3
1356 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1357 of the unused `COLLECT_KSTAT'.
1359 2007-02-11, Version 3.11.2
1360 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1361 NULL-pointer may have been passed to `printf' which causes a
1362 segfault with some libcs.
1364 2007-02-10, Version 3.11.1
1365 * df plugin: Some wrong defines have been fixed so the plugin works
1366 under Solaris again.
1367 * dns plugin: The usage of a struct has been fixed to work with
1368 non-GNU libcs.
1369 * processes plugin: Some missing defines have been added so the plugin
1370 compiles cleanly under FreeBSD and presumably other UNIXes.
1372 2006-12-22, Version 3.11.0
1373 * collectd: The new command line option `-P' makes it easier for
1374 distributors to change the location of PID-files.
1375 * collectd: The daemon shuts down faster now which makes it easier to
1376 write init.d-scripts for it.
1377 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1378 caused problems every now and then.
1379 * df plugin: New config options allow to ignore certain mountpoints,
1380 filesystem types or devices.
1381 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1382 and interprets it. It collects traffic as well as qtype, opcode and
1383 rcode counts.
1384 * email plugin: Sebastian Harl has contributed this plugin which
1385 counts received mails in categories (e. g. ham, spam, virus), spam
1386 score (as given by SpamAssassin) and check types.
1387 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1388 uses `mbmon' to gather information from sensors on the motherboard.
1389 * processes plugin: Collect detailed statistics for configured
1390 processes, that's process and thread count, CPU usage, resident
1391 segment size and pagefaults.
1392 * multimeter plugin: Peter Holik contributed a new plugin which
1393 queries multimeters.
1394 * sensors plugin: Lubos Stanek has put much effort into improving this
1395 plugin, including `extended naming', collection of voltage values
1396 and the possibility to ignore certain values.
1398 2006-12-21, Version 3.10.4
1399 * Max Kellermann has identified a bug in the server routine: When
1400 opening a socket fails the daemon will (re)try opening the socket in
1401 an endless loop, ultimately leading to a `EMFILE' error.
1403 2006-11-04, Version 3.10.3
1404 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1405 ntpd's reply was sent in more than one packet, the buffer size was
1406 calculated incorrectly, resulting in the reading of uninitialized or
1407 freed memory.
1409 2006-11-01, Version 3.10.2
1410 * The sample config file has been improved.
1411 * Errors in the manpages have been corrected.
1412 * The ping-plugin now adds hosts during initialization, not during
1413 startup. This speeds up startup when no network connectivity is
1414 available. Also, the hosts are being added later when the network is
1415 available.
1416 * Improved BSD-support for the df-plugin.
1417 * Fixed syntax errors in the swap-plugin for Mac OS X.
1418 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1419 plugin.
1420 * Don't disable the mysql-plugin if connecting to the database fails
1421 during initialization. Instead, try again in increasing intervals.
1423 2006-07-19, Version 3.10.1
1424 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1425 the apcups cannot be reached, unconnected sockets will pile up and
1426 eventually lead to `Too many open files' errors.
1428 2006-07-09, Version 3.10.0
1429 * The `disk' plugin has been ported to Darwin.
1430 * The `battery' plugin should work on many Apple computers now.
1431 * The `traffic' plugin can now ignore certain interfaces. Also,
1432 statistics for sent/received packets and errors have been added.
1433 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1434 to Anthony Gialluca for contributing this plugin and providing me
1435 with a test environment :)
1436 * A plugin for monitoring an NTP instance and the local clock drift
1437 has been added.
1439 2006-06-25, Version 3.9.4
1440 * The Solaris code in the `swap' plugin has been changed to reflect
1441 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1442 working this out.
1443 * The debugging system has been fixed to work with the Sun libc.
1444 * When built without librrd the variable `operating_mode' could be
1445 uninitialized. Thanks to David Elliot for reporting the bug.
1447 2006-06-01, Version 3.9.3
1448 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1449 operating systems also profit from the changes, but I wasn't able to
1450 check that.
1451 * Changed the build system to find the netinet-includes under FreeBSD
1452 and therefore successfully build the `liboping' library there.
1454 2006-05-09, Version 3.9.2
1455 * Applied a patch to the `liboping' library. Due to a bug in the
1456 sequence checking the `ping' plugin stopped working after
1457 approximately 7.6 days.
1459 2006-05-09, Version 3.8.5
1460 * Applied a patch to the `liboping' library. Due to a bug in the
1461 sequence checking the `ping' plugin stopped working after
1462 approximately 7.6 days.
1464 2006-04-21, Version 3.9.1
1465 * Build issues with Solaris and possible other architectures have been
1466 resolved.
1467 * Problems when building the `apache'-plugin without `libcurl' have
1468 been resolved.
1469 * A bug in the `ping' plugin has been fixed. Sorry folks.
1471 2006-04-02, Version 3.9.0
1472 * A plugin to monitor the Apache webserver has been added.
1473 <http://httpd.apache.org/>
1474 * A plugin to collect statistics about virtual servers using VServer.
1475 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1476 this plugin :)
1477 * A plugin for wireless LAN cards has been added. It monitors signal
1478 strength, link quality and noise ratio..
1479 * A plugin for Apple hardware sensors has been added.
1480 * An option to compile collectd with different `step' and `heartbeat'
1481 settings has been added. The size of RRAs is no longer static but
1482 calculated based on the settings for `step' and `width'.
1483 * The `ping' plugin can now be configured to use a certain TTL.
1484 * A plugin to monitor the hardware sensors of Apple computers has been
1485 added.
1486 * The plugins `cpu', `memory', `processes' and `traffic' have been
1487 ported to Mach/Darwin (Mac OS X).
1488 * The `log mode' has been contributed by Christophe Kalt. It writes
1489 the data into text files rather than RRD files.
1491 2006-04-09, Version 3.8.4
1492 * Applied patch by Vincent Stehlé which improves the disk-name
1493 resolution in the `hddtemp' plugin for Linux systems.
1495 2006-04-02, Version 3.8.3
1496 * Applied a patch by James Byers: The MySQL plugin was not working
1497 with MySQL 5.0.2 or later.
1499 2006-03-14, Version 3.8.2
1500 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1501 the GNU libc, because it points to `/etc/fstab' rather than
1502 `/etc/mtab'.
1504 2006-03-13, Version 3.8.1
1505 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1506 * Fixes in the debian `postinst' and `init.d' scripts.
1508 2006-03-09, Version 3.8.0
1509 * The `ping' plugin no longer uses `libping' but a self written
1510 library named `liboping'. With this library it's possible to ping
1511 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1513 2006-02-18, Version 3.7.2
1514 * A simple bug in the `battery' plugin has been fixed. It should now
1515 work with ACPI based batteries as well. Thanks to Sebastian for
1516 fixing this.
1517 * Fixing a bug that prevented collectd to be built without librrd.
1518 Thanks to Werner Heuser for reporting it.
1520 2006-02-04, Version 3.7.1
1521 * The new network code has been improved to build with older versions
1522 of glibc.
1523 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1524 to Tommie Gannert for this patch.
1526 2006-01-30, Version 3.7.0
1527 * The `battery' plugin has been added. It collects information about
1528 laptop batteries..
1529 * The MySQL plugin has been improved: It now writes two more RRD
1530 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1531 * The `cpufreq' plugin now reads another file since the file it did
1532 read so far causes much overhead in the kernel. Also, you need root
1533 to read the old file, but not to read the new one.
1534 * The `hddtemp' plugin can now be configured to connect to another
1535 address and/or port than localhost.
1536 * The `df' plugin now prefers `statvfs' over `statfs'.
1537 * The network code has been rewritten. collectd now supports unicast
1538 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1539 be set in the configfile.
1541 2006-01-24, Version 3.6.2
1542 * Due to a bug in the configfile handling collectd wouldn't start in
1543 client mode. This released fixes this.
1545 2006-01-20, Version 3.6.1
1546 * Due to a bug in `configure.in' all modules and the binary were
1547 linked against `libmysqlclient'. This issue is solved by this
1548 release.
1550 2006-01-17, Version 3.6.0
1551 * A config file has been added. This allows for loading only specific
1552 plugins.
1553 * A `df' plugin has been added.
1554 * A `mysql' plugin has been added.
1555 * The `ping' plugin doesn't entirely give up hope when a socket error
1556 occurred, but will back of and increase the intervals between tries.
1558 2006-01-21, Version 3.5.2
1559 * Fixed yet another bug in the signal handling.. Stupid typo..
1560 * Improved the ping plugin to not give up on socket errors (backport
1561 from 3.6.0).
1563 2005-12-18, Version 3.5.1
1564 * The PID-file is now deleted correctly when shutting down the daemon.
1565 * SIGINT and SIGTERM are now handled correctly.
1567 2005-12-16, Version 3.5.0 (Revision 326)
1568 * A bug in the `load' module under Solaris has been fixed.
1569 * The `users' module has been contributed by Sebastian Harl. It counts
1570 currently logged in users.
1571 * The CPU module now works under FreeBSD without the use of
1572 `libstatgrab', however SMP support is missing.
1573 * The default directories for the RRD files and the PID file now
1574 depend on the compile time setting of `localstatedir'.
1576 2005-11-15, Version 3.4.0 (Revision 236)
1577 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1578 from gentoo's bugzilla for writing the patch.
1579 * The build dependency for librrd has been removed. Binaries built
1580 without librrd are client-only and will multicast their value as
1581 with the `-c' argument.
1582 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1583 * The newly introduced `-f' switch prevents daemon initialization
1584 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1585 Barcellos for this patch.
1587 2005-11-04, Version 3.3.0 (Revision 216)
1588 * New modules have been added:
1589 - `serial', for monitoring traffic on the serial interfaces
1590 - `nfs', for graphing NFS procedure calls
1591 - `tape', traffic from/to tape devices
1592 * The memory.rrd now accepts more than 4Gig of memory.
1594 2005-10-26, Version 3.2.0 (Revision 200)
1595 * Support for graphing the processes has been added (thanks to Lyonel
1596 Vincent)
1597 * If reading from hddtemp fails collectd will increase the time
1598 between polls up to one day.
1599 * The init.d files have been improved.
1600 * Problems with the spec file have been fixed.
1602 2005-10-16, Version 3.1.0 (Revision 194)
1603 * Added the `setsid' syscall to the startup code.
1604 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1606 2005-09-30, Version 3.0.0 (Revision 184)
1607 * The ability to send/receive data to/from the network (think
1608 multicast) has been added.
1609 * Modules have been split up into shared libraries can be loaded at
1610 runtime. The biggest advantage is that the core program doesn't need
1611 to be linked against an external library.
1612 * A patch by George Kargiotakis has been applied: It fixes the sensors
1613 behaviour then more than one sensor is being queried.
1615 2005-09-16, Version 2.1.0 (Revision 172)
1616 * A module for swap statistics has been added.
1618 2005-09-09, Version 2.0.0 (Revision 135)
1619 * Filenames can no longer be configured at program startup. The only
1620 options as of this version are the directory and ping hosts.
1621 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1622 Soft-IRQ statistics are added to `System'.
1623 * Diskstats now collect read and write bytes, not sectors.
1624 * Ping statistics can now be collected for more than one host. There
1625 is no default any more: If no host is given no host will be pinged.
1626 * A self-written patch for libping has been applied so it builds
1627 cleanly.
1629 2005-09-01, Version 1.8.1 (Revision 123)
1630 * Much improved configure-script: libraries and features may now be
1631 disabled.
1632 * More detailed warnings/error messages when RRD update fails.
1634 2005-08-29, Version 1.8.0:
1635 * Support for collecting disk statistics under Solaris.
1637 2005-08-25, Version 1.7.0:
1638 * Support for libstatgrab[1] for load, memory usage and network
1639 traffic. CPU- and disk-usage are not (yet) supported, since
1640 libstatgrab returns insufficient information. I will contact the
1641 authors.
1642 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1643 aren't necessarily counted linear which is now handled correctly.
1644 [1]: http://www.i-scream.org/libstatgrab/
1646 2005-08-21, Version 1.6.0:
1647 * Basic support for Solaris: System load and cpu-usage can be
1648 collected under Solaris, too. Other stats will follow later.
1649 * Many fixes in the autoconf-script
1650 * Collection/Museum scripts have been added under contrib/museum
1651 * collectd may now be started in unprivileged mode, though ping
1652 statistics will not work.
1654 2005-07-17, Version 1.5.1:
1655 * Diskstats-RRDs now use major/minor for naming. Some systems have
1656 weird strings as disk-names..
1658 2005-07-17, Version 1.5:
1659 * A new module, diskstats, has been added. It collects information
1660 about the disks and partitions.
1662 2005-07-11, Version 1.4.2:
1663 * The meminfo module has been changed to work with more platforms
1664 and/or kernel versions.
1666 2005-07-10, Version 1.4.1: Correct traffic stats
1667 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1668 forgot to correct when I changed that module.
1670 2005-07-09, Version 1.4: More traffic stats
1671 * Traffic is now collected for all interfaces that can be found
1672 * Temperature-statistics are read from lm-sensors if available
1674 2005-07-08, Version 1.3: CPU stats
1675 * Collecting CPU statistics now
1677 2005-07-12, Version 1.2: Using syslog
1678 * collectd is now using the syslog facility to report errors, warnings
1679 and the like..
1680 * The default directory is now /var/db/collectd
1682 2005-07-10, Version 1.1: Minor changes
1683 * Nothing really useful to say ;)
1685 2005-07-09, Version 1.0: Initial Version
1686 * The following modules are provided:
1687 * Load average
1688 * Ping time
1689 * Traffic
1690 * Memory info
