471 possibly reducing the number of stats considerably. Thanks to Joey
472 Hess for reporting this bug.
473 * iptables plugin: Support for the new libiptc API has been added.
474 Thanks to Sebastian Harl for the patch. The build system has been
475 updated to the plugin only includes the shipped header files when it
476 is linked with the shipped library, too.
477 * java plugin: Delay creating the JVM until after the daemon has
478 forked. The JVM internally creates threads that are lost when
479 forking. This means that Java-based plugins are now configured
480 during the init-phase, i. e. later than other plugins.
481 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
482 to Alan Pevec for the patch.
483 * network plugin: Fix the handling of the “CacheFlush” option: The
484 value was assigned to a wrong variable. The initialization of the
485 gcrypt library, which is used for signing / encrypting traffic, has
486 been fixed. Thanks to Luke Heberling for the patch.
487 * powerdns plugin: Set a timeout when reading data from the datagram
488 socket. Handling of the “LocalSocket” option has been fixed. An
489 incorrectly used “type” has been corrected. Thanks to Luke Heberling
490 for his patches.

503 2009-06-02, Version 4.7.1
504 * Build system: Detection of Java has been improved and missing
505 details have been added to the configuration summary. Support for
506 libtool 2.2 has been added.
507 * collectd: Two bugs with the threshold checking have been fixed. The
508 first one prevented thresholds to be checked at all, the second one
509 caused wrong behavior with the persistency option. Thanks to Andrés
510 J. Díaz for fixing these problems.
511 * collectd: Handling of the `Include' configuration option has been
512 fixed.
513 * rrdtool plugin: Make sure initialization is run only once. This
514 resolves problems under Solaris and potentially other systems.
515 Thanks to Amit Gupta for reporting this bug.
516 * java plugin: Make it possible to use dots ('.') instead of slashes
517 ('/') as the class separator. Thanks to Randy Rizun for pointing
518 this out.
519 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
520 to Doug MacEachern for the patch.

528 tracking table size. Thanks to Tomasz Pala for the patch.
529 * fscache plugin: The new fscache plugin collects statistics about
530 Linux' file-system based caching framework. Thanks to Edward
531 Konetzko for the patch.
532 * gmond plugin: The new gmond plugin can receive and interpret
533 multicast traffic from Ganglia's gmond daemon.
534 * java plugin: The new java plugin exports the collectd API to Java,
535 making it possible to write extensions to collectd in Java.
536 * memcachec plugin: The new memcachec plugin queries data from a
537 memcached daemon and parses it similar to the cURL plugin. Thanks to
538 Doug MacEachern for the initial code.
539 * memcached plugin: Support for connections over UNIX domain sockets
540 has been added. Thanks to Franck Lombardi for the patch.
541 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

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

581 to Alan Pevec for the patch.
582 * powerdns plugin: Set a timeout when reading data from the datagram
583 socket. Handling of the “LocalSocket” option has been fixed. An
584 incorrectly used “type” has been corrected. Thanks to Luke Heberling
585 for his patches.

593 for reporting the bug.
595 2009-06-02, Version 4.6.3
596 * Build system, various plugins: Many build fixes for FreeBSD,
597 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
598 for many fixes and providing a build system for many platforms,
599 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
600 providing an OpenBSD system.
601 * collectd: Two bugs with the threshold checking have been fixed. The
602 first one prevented thresholds to be checked at all, the second one
603 caused wrong behavior with the persistency option. Thanks to Andrés
604 J. Díaz for fixing these problems.
605 * collectd: Handling of the `Include' configuration option has been
606 fixed.
607 * battery plugin: Don't complain about a missing directory every
608 interval.

610 Thorsten von Eicken for reporting this problem.
611 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
612 Tomasz Pala for the patch.
613 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
614 the patch.
615 * memory plugin: Fix a potential problem under Solaris.
616 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks

621 * filter subsystem: Allow `Chains' without default targets.
622 * liboping: A patch to comply with strict aliasing rules has been
623 added.
624 * timediff match: Fix a typo: The match was registered with a wrong
625 name which prevented this match to be used as documented. Thanks to
626 Bruno Prémont for finding this problem.
627 * bind plugin: Fix collection of the cached RR sets. The number of RR
628 sets currently in the cache was collected as a counter value, which
629 is nonsense. Thanks to Bruno Prémont for implementing this.
630 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
631 primarily BSDs, don't take it well and crash.
632 * oracle plugin: Portability to 64 bit systems has been improved.
633 * postgresql plugin: The default configuration has been improved.
634 * rrdtool plugin: Fix a possible race condition: If the network plugin
635 is brought and dispatches a value before the rrdtool plugin is
636 initialized, the daemon may crash.
638 2009-02-22, Version 4.6.1
639 * collectd: Many documentation fixes.
640 * Collectd::Unixsock: Error handling has been improved.
641 * regex match: Don't link with the PCRE library.
642 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
643 for finding and fixing most of them.
644 * ipmi plugin: Fix an off-by-one error which could cause segmentation
645 faults. Thanks to Peter Holik for his patch.
647 2009-02-16, Version 4.6.0
648 * collectd: Added the `filter chain' infrastructure, which allows the
649 user to use `matches' and `targets' to control value processing.
650 * collectd: The new `-T' command line argument allows more in-depth
651 testing of a configuration. Thanks to Doug MacEachern for the patch.
652 * collectd-nagios: The Nagios integration command has been updated to
653 use libcollectdclient. The `percentage' aggregation function has
654 been added. Thanks to Fabian Linzberger for the patch.
655 * libcollectdclient: A library which abstracts communication with the
656 unixsock plugin for clients has been added.
657 * regex match: Match values by their identifies using regular
658 expressions.
659 * timediff match: Match for values with an invalid timestamp.
660 * value match: Select values by their data sources' values.
661 * notification target: Create and dispatch a notification.
662 * replace target: Replace parts of an identifier using regular
663 expressions.
664 * set target: Set (overwrite) entire parts of an identifier.
665 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
666 statistics, allowing very detailed name server statistics. Thanks to
667 Bruno Prémont for this plugin.
668 * cpu plugin: Report `interrupt' separately when using
669 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
670 example for native OpenBSD support, has been added. Thanks to Simon
671 Kuhnle for the patch.
672 * csv plugin: Make it possible to write values to STDOUT instead of
673 files. This is meant for testing purposes mostly. The output written
674 to STDOUT is compatible with the exec plugin. Thanks to Doug
675 MacEachern for the patch.
676 * curl plugin: This new plugin can be used to read web pages and parse
677 them using the same mechanism that's used in the tail plugin.
678 * dbi plugin: This new plugin allows you to connect to a variety of
679 relational databases and use SQL to gather custom statistics from
680 it. It is similar to the already existing PostgreSQL plugin but uses
681 libdbi to communicate with the database(s).
682 * interface plugin: Use the ignorelist framework when selecting /
683 ignoring interfaces. This allows one to use regular expressions to
684 select interfaces, too.
685 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
686 Thanks to Bruno Prémont for this patch.
687 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
688 for the patch.
689 * mysql plugin: Allow connecting to a database via the UNIX domain
690 socket, too. Thanks to Mirko Buffoni for the patch.

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

747 faults. Thanks to Peter Holik for his patch.
748 * tcpconns plugin: An endianness problem has been fixed in the *BSD
749 code. Thanks to "thated" for reporting this.
751 2009-01-02, Version 4.5.2
752 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
753 file may be in both locations, especially when the database was
754 installed in a non-standard path. Thanks to Dusty Doris for
755 reporting this.
756 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
757 Solaris, in the configure script automatically.
758 * build system, tcpconns plugin: Check for `kvm_nlist' and
759 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
760 library with similar functions to the BSD variant, but doesn't
761 provide these necessary functions.
762 * collectd.conf(5): Various fixes and clarifications.
763 * collectd: Remove a GNUism (unnamed unions), thus improving
764 portability.
765 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
766 This solves portability problems, especially for Solaris.
767 * dns plugin: Fix a portability problem with NetBSD.
768 * filecount plugin: Fix an off-by-one error. This error may cause a
769 segmentation fault.
770 * network plugin: Fix the handling of `type' in the network protocol.
771 Due to a programming mistake, only 4 or 8 bytes would be copied to a
772 much larger buffer. This caused the `type' to be transferred much
773 more often than necessary. In some cases, e. g. the `cpu' and
774 `cpufreq' plugins being used at the same time, data may be corrupted
775 in those files. Thanks to Bruno Prémont for debugging and reporting
776 this issue.
777 * processes plugin: Fix a possible segmentation fault when specifying
778 invalid configuration options.
779 * unixsock plugin: Make sure the initialization function is run only
780 once. This resolves a file descriptor leak under systems which run
781 the initialization more than once, such as Solaris.
783 2008-10-16, Version 4.5.1
784 * build system: Change `--enable-<plugin>' to abort with an error if
785 dependencies are not met. Thanks to Bruno Prémont for the patch.
786 Also, the poisoning of various string functions has been restricted
787 to debug builds.
788 * collectd: Fix a memory leak in the global value cache. With every
789 *missing* value a couple of bytes would be leaked. Another memory
790 leak in the configuration handling code has been fixed. Thanks to
791 Niraj Tolia for reporting these issues.
792 * collectd: Fix an off-by-one error in the ignorelist functionality.
793 When using regular expressions, the last character would be missing,
794 possibly matching differently from what one would expect.
795 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
796 problem.
797 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
798 Linzberger for reporting the bug.
799 * iptables plugin: Fix an off-by-one error. If a string was just one
800 character too long, it was truncated instead of reporting an error.
801 * network plugin: Fix a memory leak in the configuration handling
802 code. Thanks to Niraj Tolia for reporting this issue.
803 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
804 * postgresql plugin: Don't reopen connection during reinitialization.
805 This fixes a bug under Solaris and potentially other platforms.
806 Missing calls to `PQclear' have been added, too. This fixes memory
807 leaks. Thanks to ``Admin'' for reporting these bugs.
808 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
809 library.
810 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
811 problems with some `libc's. Thanks to Matthias Lay for reporting the
812 bug.
814 2008-09-04, Version 4.5.0
815 * collectd: Added the ability to flush certain identifiers.
816 * collectd: The concept of `notification meta data' has been
817 introduced.
818 * filecount plugin: The new filecount plugin counts the number of
819 files in a directory and its subdirectories.
820 * ipmi plugin: Sensor names have been changed to ensure unique names.
821 Notifications upon added and removed sensors can now be generated.
822 * notify_desktop plugin: This new plugin sends notifications to the
823 X desktop using the structure defined in the `Desktop Notification
824 Specification'.
825 * notify_email plugin: This new plugin sends out notifications via
826 email, using the `esmtp' library.
827 * onewire plugin: The new experimental(!) onewire plugin reads values,
828 such as temperatures, from sensors connected to the computer via the
829 onewire bus.
830 * perl plugin: Improved synchronized access to internal data structures
831 and fixed a possible dead-lock.
832 * perl plugin: Added the ability to flush certain identifiers and marked
833 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
834 plugin_flush().
835 * perl plugin: Added the ability to configure Perl plugins.
836 * postgresql plugin: The new postgresql plugin collects statistics
837 about or from a PostgreSQL database.
838 * processes plugin: The `ProcessMatch' option has been added.
839 * rrdtool plugin: Implement throttling of the `update queue' to lessen
840 IO load.
841 * tcpconns plugin: This plugin has been ported to OpenBSD.
842 * thermal plugin: The new thermal plugin collects system temperatures
843 using Linux ACPI thermal zone data.
845 2009-01-02, Version 4.4.5
846 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
847 file may be in both locations, especially when the database was
848 installed in a non-standard path. Thanks to Dusty Doris for
849 reporting this.
850 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
851 Solaris, in the configure script automatically.
852 * collectd.conf(5): Various fixes and clarifications.
853 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
854 portability problems, especially for Solaris.
855 * dns plugin: Fix a portability problem with NetBSD.
856 * network plugin: Fix the handling of `type' in the network protocol.
857 Due to a programming mistake, only 4 or 8 bytes would be copied to a
858 much larger buffer. This caused the `type' to be transferred much
859 more often than necessary. In some cases, e. g. the `cpu' and
860 `cpufreq' plugins being used at the same time, data may be corrupted
861 in those files. Thanks to Bruno Prémont for debugging and reporting
862 this issue.
863 * unixsock plugin: Make sure the initialization function is run only
864 once. This resolves a file descriptor leak under systems which run
865 the initialization more than once, such as Solaris.
867 2008-10-16, Version 4.4.4
868 * build system: Change `--enable-<plugin>' to abort with an error if
869 dependencies are not met. Thanks to Bruno Prémont for the patch.
870 Also, the poisoning of various string functions has been restricted
871 to debug builds.
872 * collectd: Fix a memory leak in the global value cache. With every
873 *missing* value a couple of bytes would be leaked. Another memory
874 leak in the configuration handling code has been fixed. Thanks to
875 Niraj Tolia for reporting these issues.
876 * collectd: Fix an off-by-one error in the ignorelist functionality.
877 When using regular expressions, the last character would be missing,
878 possibly matching differently from what one would expect.
879 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
880 problem.
881 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
882 Linzberger for reporting the bug.
883 * network plugin: Fix a memory leak in the configuration handling
884 code. Thanks to Niraj Tolia for reporting this issue.
885 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
886 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
887 problems with some `libc's. Thanks to Matthias Lay for reporting the
888 bug.
890 2008-09-01, Version 4.4.3
891 * collectd: Fix a memory leak in the threshold checking code.

902 of disks.
903 * dns plugin: Fix compilation errors with BIND versions 19991001
904 through 19991005.
905 * network plugin: Bugfix in the init routine: The init function
906 cleared a buffer regardless of its contents. This could lead to lost
907 values under Solaris.
908 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
909 * vserver plugin: Remove usage of the thread-unsafe `readdir'
910 function.
911 * wireless plugin: Work around incorrect noise and power values
912 returned by some broken drivers.
914 2008-06-03, Version 4.4.1
915 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
916 to kyrone for reporting this.

918 threshold checking.
919 * collectd-nagios: Fix the protocol used to communicate with the
920 daemon.
921 * perl plugin: Fail noisily, but don't shutdown the daemon, if
922 initialization has errors. An issue with Perl 5.10 has been fixed.
923 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
924 René Rebe and Siegmund Gorr for reporting this.
926 2008-05-06, Version 4.4.0
927 * collectd: Internal code cleanups.
928 * collectd: Added support for a `Flush' command in the unixsock and
929 exec plugins. This command can be used to force a plugin (or all) to
930 flush its values to disk.
931 * collectd: Thresholds can now be configured to apply to one data
932 source only, making it possible to configure different thresholds
933 for each data source.
934 * apache, nginx plugins: Added the possibility to disable host and/or
935 peer verification.
936 * ascent plugin: The new ascent plugin reads and parses the statistics
937 page of an Ascent server.
938 * cpu plugin: Support for the statgrab library has been added.
939 * disk plugin: The possibility to ignore certain disks or collect only
940 specific disks has been added.
941 * disk plugin: Support for the statgrab library has been added.
942 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
943 sensor values via IPMI, the intelligent platform management
944 interface.
945 * iptables plugin: The iptc library that is used by the iptables
946 plugin has been added to the distribution, because it is not
947 provided by all distributions and removed from at least one.
948 * powerdns plugin: The new powerdns plugin reads statistics from an
949 authoritative or a recursing PowerDNS name server.
950 * rrdtool plugin: The size of the files generated with the default
951 configuration has been decreased.
952 * tail plugin: The new tail plugin can be used to gather statistics by
953 continuously reading from log files.
954 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
955 TeamSpeak2 server and collects statistics about the number of users
956 and number of channels.
957 * users plugin: Support for the statgrab library has been added.
958 * vmem plugin: The new vmem plugin collects very detailed statistics
959 about the virtual memory subsystem of Linux.
961 2008-08-30, Version 4.3.4
962 * Build system: Improved detection of and linking with the statgrab
963 library.
964 * collectd: Portability fixes, especially to determine endianess more
965 reliable.
966 * Various plugins: Fix format strings.
967 * disk plugin: A fix for giving disks under Linux 2.4 the right names
968 again has been applied.
969 * memcached plugin: Fix a too short timeout and a related file
970 descriptor leak.
971 * memory plugin: A typo in the libstatgrab code has been fixed.
972 * network plugin: A fix in the initialization function solves problems
973 under Solaris.
974 * nginx plugin: A thread-unsafe function has been replaced.
975 * vserver plugin: A thread-unsafe function has been replaced.
976 * wireless plugin: A work-around for broken wireless drivers has been
977 added.
979 2008-04-22, Version 4.3.3
980 * build system: Improved detection of several libraries, especially if
981 they are in non-standard paths.
982 * build system: Portability fixes: Automatically define "_REENTRANT"
983 if the libc expects it.
984 * collectd: Error and warning messages have been improved.
985 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
986 using them.
987 * apache plugin: Allocate new memory when reading a webpage instead of
988 using a buffer of static size.
989 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
990 the program.
991 * hddtemp plugin: Error and warning messages have been improved.
992 * sensors plugin: Fix sensor collection for some chip types.
994 2008-03-29, Version 4.3.2
995 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
996 `Persist' threshold options.
997 * collectd: Fix handling of missing values in the global value cache.
998 * collectd: Improved error messages when parsing the configuration.
999 * sensors plugin: Fix temperature collection with libsensors4.
1000 * unixsock plugin: Fix mixed input and output operation on streams.
1001 * wireless plugin: Fix reading noise value.
1003 2008-03-05, Version 4.3.1
1004 * exec plugin: Set supplementary group IDs.
1005 * network plugin:
1006 + Use `memcpy' when constructing/parsing a package to avoid
1007 alignment problems on weird architectures, such as Sparc.
1008 + Translate doubles to/from the x86 byte representation to ensure
1009 cross-platform compatibility.
1010 * ping plugin: Correct the handling of the `TTL' setting.
1011 * swap plugin: Reapply a patch for Solaris.
1012 * tcpconns plugin: Portability improvements.
1014 2008-02-18, Version 4.3.0
1015 * collectd: Notifications have been added to the daemon. Notifications
1016 are status messages that may be associated with a data instance.
1017 * collectd: Threshold checking has been added to the daemon. This
1018 means that you can configure threshold values for each data
1019 instance. If this threshold is exceeded a notification will be
1020 created.
1021 * collectd: The new `FQDNLookup' option tells the daemon to use the
1022 full qualified domain name as the hostname, not just the host part
1023 es returned by `gethostname(2)'.
1024 * collectd: Support for more than one `TypesDB' file has been added.
1025 This is useful when one such file is included in a package but one
1026 wants to add custom type definitions.
1027 * collectd: The `Include' config option has been expanded to handle
1028 entire directories and shell wildcards.
1029 * collectdmon: The new `collectdmon' binary detects when collectd
1030 terminates and automatically restarts it again.
1031 * csv plugin: The CSV plugin is now able to store counter values as a
1032 rate, using the `StoreRates' configuration option.
1033 * exec plugin: Handling of notifications has been added and the
1034 ability to pass arguments to the executed programs has been added.
1035 * hddtemp plugin: The new `TranslateDevicename' option lets you
1036 disable the translation from device names to major-minor-numbers.
1037 * logfile plugin: Handling of notifications has been added.
1038 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
1039 domain name lookups in this plugin.
1040 * perl plugin: Many internal changes added support for handling multiple
1041 threads making the plugin reasonably usable inside collectd. The API has
1042 been extended to support notifications and export global variables to
1043 Perl plugins; callbacks now have to be identified by name rather than a
1044 pointer to a subroutine. The plugin is no longer experimental.
1045 * uuid plugin: The new UUID plugin sets the hostname to an unique
1046 identifier for this host. This is meant for setups where each client
1047 may migrate to another physical host, possibly going through one or
1048 more name changes in the process. Thanks to Richard Jones from
1049 Red Hat's Emerging Technology group for this plugin.
1050 * libvirt: The new libvirt plugin uses the `libvirt' library to query
1051 CPU, disk and network statistics about guest systems on the same
1052 physical server. Thanks to Richard Jones from Red Hat's Emerging
1053 Technology group for this plugin.
1055 2008-04-22, Version 4.2.7
1056 * build system: Improved detection of several libraries, especially if
1057 they are in non-standard paths.
1058 * build system: Portability fixes: Automatically define "_REENTRANT"
1059 if the libc expects it.
1060 * collectd: Error and warning messages have been improved.
1061 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
1062 using them.
1063 * apache plugin: Allocate new memory when reading a webpage instead of
1064 using a buffer of static size.
1065 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
1066 the program.
1067 * hddtemp plugin: Error and warning messages have been improved.
1068 * sensors plugin: Fix sensor collection for some chip types.
1070 2008-03-29, Version 4.2.6
1071 * collectd: Improved error messages when parsing the configuration.
1072 * sensors plugin: Fix temperature collection with libsensors4.
1073 * unixsock plugin: Fix mixed input and output operation on streams.
1074 * wireless plugin: Fix reading noise value.
1076 2008-03-04, Version 4.2.5
1077 * apache plugin: Improved initialization and error messages.
1078 * exec plugin: Set supplementary group IDs.
1079 * network plugin:
1080 + Create separate threads for reading from the socket and parsing
1081 and dispatching incoming packets. Versions prior to this may have
1082 problems in high-load situations, where the socket receive buffers
1083 overflows, resulting in gaps in the data.
1084 + Use `memcpy' when constructing/parsing a package to avoid
1085 alignment problems on weird architectures, such as Sparc.
1086 + Translate doubles to/from the x86 byte representation to ensure
1087 cross-platform compatibility.
1088 * ping plugin: Correct the handling of the `TTL' setting.
1089 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
1090 * swap plugin: Reapply a patch for Solaris.
1091 * tcpconns plugin: Portability improvements.
1093 2008-01-21, Version 4.2.4
1094 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1095 the permission on the socket as documented in the manpage. Thanks to
1096 Evgeny Chukreev for fixing this issue.
1097 * collectd: The documentation has been improved.
1099 2007-12-28, Version 4.2.3
1100 * sensors plugin: Updated the plugin to build and work with version 3
1101 of the libsensors library.
1103 2007-12-15, Version 4.2.2
1104 * nginx plugin: Incorrect comparison of strings lead to a segfault
1105 when using the plugin. Thanks to Saulius Grigaliunas for fixing
1106 this.
1107 * logfile plugin: The config option `Timestamp' was handled
1108 incorrectly and basically always active. Thanks to Luke Heberling
1109 for fixing this.
1111 2007-11-08, Version 4.2.1
1112 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
1113 enabled on the host.
1114 * snmp plugin: Fix a memory leak.
1116 2007-10-27, Version 4.2.0
1117 * collectd: The new config option `Include' lets you include other
1118 configfiles and thus split up your config into smaller parts. This
1119 may be especially interesting for the snmp plugin to keep the data
1120 definitions separate from the host definitions.
1121 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
1122 (number of connections, octets and packets for each service and
1123 destination). Thanks to Sebastian Harl for this plugin.
1124 * memcached plugin: The new `memcached' plugin connects to a memcached
1125 daemon process and collects statistics of this distributed caching
1126 system. Thanks to Antony Dovgal for contributing this plugin.
1127 * nginx plugin: The new `nginx' plugin reads the status page of an
1128 nginx daemon and saves the handled connections and requests.
1129 * perl plugin: Many changes, including the added `EnableDebugger'
1130 config option which lets you debug your Perl plugins more easily.
1131 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1132 be more thread-safe otherwise by locking calls to the library.
1133 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
1134 correct the values returned by SNMP-agents. If a <data> block is
1135 defined as `table' the instance is now optional. The sequence number
1136 is used as the type-instance in this case. The new `InstancePrefix'
1137 option allows to add arbitrary prefixes to the type-instance.
1138 * tcpconns plugin: The new `tcpconns' plugin collects the number of
1139 certain TCP connections and what state they're in. This can be used
1140 to see how many connections your FTP server has to handle or how
1141 many outgoing connections your mailserver has open.
1143 2008-01-11, Version 4.1.6
1144 * unixsock plugin: A bug in the unixsock plugin caused it not to set
1145 the permission on the socket as documented in the manpage. Thanks to
1146 Evgeny Chukreev for fixing this issue.
1147 * collectd: The documentation has been improved.
1149 2007-12-27, Version 4.1.5
1150 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
1151 memory situations.
1152 * sensors plugin: Updated the plugin to build and work with version 3
1153 of the libsensors library.
1155 2007-11-08, Version 4.1.4
1156 * Build system: Improve detection of the rrd library, especially if
1157 it's in a non-standard location.
1158 * Build system: A bug when parsing the argument for
1159 `--with-libnetsnmp' has been fixed.
1160 * collectd: Implement `strerror_r' if the libc doesn't provide it.
1161 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
1162 a deadlock or delay when shutting down the daemon.
1163 * snmp plugin: Fix a memory leak.
1165 2007-10-24, Version 4.1.3
1166 * collectd: A build issue under Solaris has been resolved by renaming
1167 data types.
1168 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
1169 be more thread-safe otherwise by locking calls to the library.
1171 2007-09-28, Version 4.1.2
1172 * apcups plugin: Fix reporting of the `load percent' data.
1173 * wireless plugin: Correct the handling of cards returning signal and
1174 noise quality as percentage.
1175 * perl plugin: Fix a possible buffer overflow in get_module_name().
1176 * build system: Further improve the detection of libraries.
1177 * netlink plugin: Build issues under some older versions of the Linux
1178 includes (i. e. Debian Sarge) have been fixed.
1179 * snmp plugin: Fix a potential segfault when a host times out. Add
1180 support for the `timeticks' type.
1182 2007-09-12, Version 4.1.1
1183 * Build system: The detection of `libnetlink' has been improved.
1184 * collectd: The documentation has been fixed in numerous places.
1185 * exec plugin: Setting the group under which to run a program has been
1186 fixed.
1187 * collectd: The `sstrerror' function was improved to work correctly
1188 with the broken GNU version of `strerror_r'.
1189 * collectd: Write an error message to STDERR when loading of a plugin
1190 fails.
1191 * apcups plugin: Fix the `types' used to submit the values: They still
1192 has an `apcups_' prefix which doesn't work anymore.
1193 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1194 whatever the client thinks is `now'..
1196 2007-09-01, Version 4.1.0
1197 * Build system: The build system has been changed to automatically
1198 disable all plugins, which are missing dependencies. The dependency
1199 checking has been removed from the plugins themselves to remove
1200 redundancy.
1201 * Flexible interval: The interval of collected data is now sent along
1202 with the data itself over the network, so that the interval-settings
1203 of server and clients no longer needs to match.
1204 * netlink plugin: The new `netlink' plugin connects to the Linux
1205 kernel using a netlink socket and uses it to query information about
1206 interfaces, qdiscs and classes.
1207 * rrdtool plugin: The cache is now dumped to disk in an extra thread
1208 to not block data collection.
1209 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
1210 network devices, such as switches, routers, thermometers, rack
1211 monitoring servers, etc. The collectd-snmp(5) manpage documents this
1212 plugin.
1213 * unixsock plugin: Added the `LISTVAL' command.
1214 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
1215 of music played with xmms.
1217 2007-09-28, Version 4.0.9
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().
1223 2007-09-12, Version 4.0.8
1224 * collectd: The `sstrerror' function was improved to work correctly
1225 with the broken GNU version of `strerror_r'.
1226 * collectd: Write an error message to STDERR when loading of a plugin
1227 fails.
1228 * apcups plugin: Fix the `types' used to submit the values: They still
1229 has an `apcups_' prefix which doesn't work anymore.
1230 * rrdtool plugin: Create new RRD-files with the `begin' time set to
1231 whatever the client thinks is `now'..
1233 2007-08-26, Version 4.0.7
1234 * documentation: Some typos have been fixed and some information has
1235 been improved.
1236 * build system: Many fixes for detecting libraries in unusual places,
1237 such as on RedHat systems. The affected libraries are `libcurl',
1238 `libmysql', and `libupsclient'.
1239 * network plugin: Allow the `Port' option to be specified as a number
1240 (i. e. without quotes).
1241 * nut plugin: A fix allows linking the nut plugin against
1242 libupsclient, version >= 2.2.0.
1243 * processes plugin: Fix a potential segmentation fault.
1245 2007-07-30, Version 4.0.6
1246 * sensors plugin: Fix the ignorelist functionality: Only the `type
1247 instance' was used to match against the list, but the documentation
1248 told otherwise. This release fixes the code, so it complies with the
1249 documentation.
1250 * syslog plugin: Call `openlog' right when the plugin is loaded, so
1251 configuration messages will end up in the logging facility.
1252 * conrtib/fedora: The contributed specfile for Fedora has been
1253 updated.
1255 2007-07-05, Version 4.0.5
1256 * Portability: More fixes for OpenBSD have been included.
1258 2007-06-24, Version 4.0.4
1259 * cpu plugin: Fixed the Solaris code.
1260 * dns plugin: Fixed a build issue for OpenBSD.
1261 * interface plugin: Fixed the Solaris code.
1262 * load plugin: Fixed the alternative `/proc' Linux code.
1263 * memory plugin: Fixed the Solaris code.
1264 * oconfig: Don't require `-lfl' anymore.
1266 2007-06-19, Version 4.0.3
1267 * cpu plugin: Fix the Darwin / Mac OS X code.
1268 * ping plugin: Use the return value of `getpid', not its address.
1269 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1270 initialized correctly.
1271 * configure: Added `--with-nan-emulation' to aid cross compilation.
1273 2007-06-12, Version 4.0.2
1274 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1275 they're given in numerically form.
1277 2007-06-07, Version 4.0.1
1278 * iptables plugin: A bug in the configuration routine has been fixed.
1279 Setting a comment in the configfile will no longer cause a
1280 segmentation fault.
1282 2007-06-03, Version 4.0.0
1283 * collectd: The plugin-infrastructure has been changed to allow for
1284 more types of plugins, namely `write' and `log' plugins.
1285 * collectd: The read-function has been changed to read many plugins in
1286 parallel, using threads. Thus, plugins generally need to use
1287 thread-safe functions from now on.
1288 * collectd: The '-t' command line options allows to perform syntax tests
1289 of the configuration file and exit immediately.
1290 * csv plugin: The new `csv' plugin handles output to `comma separated
1291 values'-files.
1292 * rrdtool plugin: The new `rrdtool' plugin handles output to
1293 RRD-files. Data can be cached to combine multiple updates into one
1294 write to increase IO-performance.
1295 * network plugin: The new `network' plugin handles IO via the network.
1296 It implements a different, much more extensible protocol which can
1297 combine many values in one packet, decreasing the number of UDP-
1298 packets being sent. It can read from and send to the network and
1299 with the appropriate configuration even forward packets to other
1300 networks.
1301 * unixsock plugin: The new `unixsock' plugin provides an interface to
1302 communicate with the daemon while it is running. Right now the
1303 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1304 come.
1305 * perl plugin: The new `perl' plugin allows you to write extensions
1306 for collectd in the scripting-language Perl.
1307 * logfile plugin: The new `logfile' plugin writes logmessages to files
1308 or STDOUT or STDERR.
1309 * syslog plugin: The new `syslog' plugin sends logmessages to the
1310 system's syslog daemon.
1311 * entropy plugin: The new `entropy' plugin collects the amount of
1312 entropy currently being available to the system.
1313 * exec plugin: The new `exec' plugin forks child processes and reads
1314 back values provided by the forked processes.
1315 * iptables plugin: The new `iptables' plugin reads counters from
1316 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1317 plugin.
1318 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1319 to Peter Holik for contributing this plugin.
1320 * nut plugin: The new `nut' plugin connects the upsd of the `network
1321 ups tools' and reads information about the connected UPS.
1322 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1323 connections) field was added by Florent Monbillard.
1324 * collectd-nagios: The new `collectd-nagios' binary queries values
1325 from collectd, parses them and exits according to Nagios-standards.
1326 * manpages: The manpages have been improved a lot.
1328 2007-09-28, Version 3.11.7
1329 * wireless plugin: Correct the handling of cards returning signal and
1330 noise quality as percentage.
1332 2007-08-31, Version 3.11.6
1333 * processes plugin: Fix a potential segmentation fault.
1335 2007-05-29, Version 3.11.5
1336 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1337 * ntpd plugin: Fix a potential buffer overflow.
1338 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1339 were accounted as `zombies'.
1341 2007-04-10, Version 3.11.4
1342 * dns plugin: Change the order of includes to make the plugin compile
1343 under FreeBSD.
1345 2007-03-30, Version 3.11.3
1346 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1347 of the unused `COLLECT_KSTAT'.
1349 2007-02-11, Version 3.11.2
1350 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1351 NULL-pointer may have been passed to `printf' which causes a
1352 segfault with some libcs.
1354 2007-02-10, Version 3.11.1
1355 * df plugin: Some wrong defines have been fixed so the plugin works
1356 under Solaris again.
1357 * dns plugin: The usage of a struct has been fixed to work with
1358 non-GNU libcs.
1359 * processes plugin: Some missing defines have been added so the plugin
1360 compiles cleanly under FreeBSD and presumably other UNIXes.
1362 2006-12-22, Version 3.11.0
1363 * collectd: The new command line option `-P' makes it easier for
1364 distributors to change the location of PID-files.
1365 * collectd: The daemon shuts down faster now which makes it easier to
1366 write init.d-scripts for it.
1367 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1368 caused problems every now and then.
1369 * df plugin: New config options allow to ignore certain mountpoints,
1370 filesystem types or devices.
1371 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1372 and interprets it. It collects traffic as well as qtype, opcode and
1373 rcode counts.
1374 * email plugin: Sebastian Harl has contributed this plugin which
1375 counts received mails in categories (e. g. ham, spam, virus), spam
1376 score (as given by SpamAssassin) and check types.
1377 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1378 uses `mbmon' to gather information from sensors on the motherboard.
1379 * processes plugin: Collect detailed statistics for configured
1380 processes, that's process and thread count, CPU usage, resident
1381 segment size and pagefaults.
1382 * multimeter plugin: Peter Holik contributed a new plugin which
1383 queries multimeters.
1384 * sensors plugin: Lubos Stanek has put much effort into improving this
1385 plugin, including `extended naming', collection of voltage values
1386 and the possibility to ignore certain values.
1388 2006-12-21, Version 3.10.4
1389 * Max Kellermann has identified a bug in the server routine: When
1390 opening a socket fails the daemon will (re)try opening the socket in
1391 an endless loop, ultimately leading to a `EMFILE' error.
1393 2006-11-04, Version 3.10.3
1394 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1395 ntpd's reply was sent in more than one packet, the buffer size was
1396 calculated incorrectly, resulting in the reading of uninitialized or
1397 freed memory.
1399 2006-11-01, Version 3.10.2
1400 * The sample config file has been improved.
1401 * Errors in the manpages have been corrected.
1402 * The ping-plugin now adds hosts during initialization, not during
1403 startup. This speeds up startup when no network connectivity is
1404 available. Also, the hosts are being added later when the network is
1405 available.
1406 * Improved BSD-support for the df-plugin.
1407 * Fixed syntax errors in the swap-plugin for Mac OS X.
1408 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1409 plugin.
1410 * Don't disable the mysql-plugin if connecting to the database fails
1411 during initialization. Instead, try again in increasing intervals.
1413 2006-07-19, Version 3.10.1
1414 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1415 the apcups cannot be reached, unconnected sockets will pile up and
1416 eventually lead to `Too many open files' errors.
1418 2006-07-09, Version 3.10.0
1419 * The `disk' plugin has been ported to Darwin.
1420 * The `battery' plugin should work on many Apple computers now.
1421 * The `traffic' plugin can now ignore certain interfaces. Also,
1422 statistics for sent/received packets and errors have been added.
1423 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1424 to Anthony Gialluca for contributing this plugin and providing me
1425 with a test environment :)
1426 * A plugin for monitoring an NTP instance and the local clock drift
1427 has been added.
1429 2006-06-25, Version 3.9.4
1430 * The Solaris code in the `swap' plugin has been changed to reflect
1431 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1432 working this out.
1433 * The debugging system has been fixed to work with the Sun libc.
1434 * When built without librrd the variable `operating_mode' could be
1435 uninitialized. Thanks to David Elliot for reporting the bug.
1437 2006-06-01, Version 3.9.3
1438 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1439 operating systems also profit from the changes, but I wasn't able to
1440 check that.
1441 * Changed the build system to find the netinet-includes under FreeBSD
1442 and therefore successfully build the `liboping' library there.
1444 2006-05-09, Version 3.9.2
1445 * Applied a patch to the `liboping' library. Due to a bug in the
1446 sequence checking the `ping' plugin stopped working after
1447 approximately 7.6 days.
1449 2006-05-09, Version 3.8.5
1450 * Applied a patch to the `liboping' library. Due to a bug in the
1451 sequence checking the `ping' plugin stopped working after
1452 approximately 7.6 days.
1454 2006-04-21, Version 3.9.1
1455 * Build issues with Solaris and possible other architectures have been
1456 resolved.
1457 * Problems when building the `apache'-plugin without `libcurl' have
1458 been resolved.
1459 * A bug in the `ping' plugin has been fixed. Sorry folks.
1461 2006-04-02, Version 3.9.0
1462 * A plugin to monitor the Apache webserver has been added.
1463 <http://httpd.apache.org/>
1464 * A plugin to collect statistics about virtual servers using VServer.
1465 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1466 this plugin :)
1467 * A plugin for wireless LAN cards has been added. It monitors signal
1468 strength, link quality and noise ratio..
1469 * A plugin for Apple hardware sensors has been added.
1470 * An option to compile collectd with different `step' and `heartbeat'
1471 settings has been added. The size of RRAs is no longer static but
1472 calculated based on the settings for `step' and `width'.
1473 * The `ping' plugin can now be configured to use a certain TTL.
1474 * A plugin to monitor the hardware sensors of Apple computers has been
1475 added.
1476 * The plugins `cpu', `memory', `processes' and `traffic' have been
1477 ported to Mach/Darwin (Mac OS X).
1478 * The `log mode' has been contributed by Christophe Kalt. It writes
1479 the data into text files rather than RRD files.
1481 2006-04-09, Version 3.8.4
1482 * Applied patch by Vincent Stehlé which improves the disk-name
1483 resolution in the `hddtemp' plugin for Linux systems.
1485 2006-04-02, Version 3.8.3
1486 * Applied a patch by James Byers: The MySQL plugin was not working
1487 with MySQL 5.0.2 or later.
1489 2006-03-14, Version 3.8.2
1490 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1491 the GNU libc, because it points to `/etc/fstab' rather than
1492 `/etc/mtab'.
1494 2006-03-13, Version 3.8.1
1495 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1496 * Fixes in the debian `postinst' and `init.d' scripts.
1498 2006-03-09, Version 3.8.0
1499 * The `ping' plugin no longer uses `libping' but a self written
1500 library named `liboping'. With this library it's possible to ping
1501 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1503 2006-02-18, Version 3.7.2
1504 * A simple bug in the `battery' plugin has been fixed. It should now
1505 work with ACPI based batteries as well. Thanks to Sebastian for
1506 fixing this.
1507 * Fixing a bug that prevented collectd to be built without librrd.
1508 Thanks to Werner Heuser for reporting it.
1510 2006-02-04, Version 3.7.1
1511 * The new network code has been improved to build with older versions
1512 of glibc.
1513 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1514 to Tommie Gannert for this patch.
1516 2006-01-30, Version 3.7.0
1517 * The `battery' plugin has been added. It collects information about
1518 laptop batteries..
1519 * The MySQL plugin has been improved: It now writes two more RRD
1520 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1521 * The `cpufreq' plugin now reads another file since the file it did
1522 read so far causes much overhead in the kernel. Also, you need root
1523 to read the old file, but not to read the new one.
1524 * The `hddtemp' plugin can now be configured to connect to another
1525 address and/or port than localhost.
1526 * The `df' plugin now prefers `statvfs' over `statfs'.
1527 * The network code has been rewritten. collectd now supports unicast
1528 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1529 be set in the configfile.
1531 2006-01-24, Version 3.6.2
1532 * Due to a bug in the configfile handling collectd wouldn't start in
1533 client mode. This released fixes this.
1535 2006-01-20, Version 3.6.1
1536 * Due to a bug in `configure.in' all modules and the binary were
1537 linked against `libmysqlclient'. This issue is solved by this
1538 release.
1540 2006-01-17, Version 3.6.0
1541 * A config file has been added. This allows for loading only specific
1542 plugins.
1543 * A `df' plugin has been added.
1544 * A `mysql' plugin has been added.
1545 * The `ping' plugin doesn't entirely give up hope when a socket error
1546 occurred, but will back of and increase the intervals between tries.
1548 2006-01-21, Version 3.5.2
1549 * Fixed yet another bug in the signal handling.. Stupid typo..
1550 * Improved the ping plugin to not give up on socket errors (backport
1551 from 3.6.0).
1553 2005-12-18, Version 3.5.1
1554 * The PID-file is now deleted correctly when shutting down the daemon.
1555 * SIGINT and SIGTERM are now handled correctly.
1557 2005-12-16, Version 3.5.0 (Revision 326)
1558 * A bug in the `load' module under Solaris has been fixed.
1559 * The `users' module has been contributed by Sebastian Harl. It counts
1560 currently logged in users.
1561 * The CPU module now works under FreeBSD without the use of
1562 `libstatgrab', however SMP support is missing.
1563 * The default directories for the RRD files and the PID file now
1564 depend on the compile time setting of `localstatedir'.
1566 2005-11-15, Version 3.4.0 (Revision 236)
1567 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1568 from gentoo's bugzilla for writing the patch.
1569 * The build dependency for librrd has been removed. Binaries built
1570 without librrd are client-only and will multicast their value as
1571 with the `-c' argument.
1572 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1573 * The newly introduced `-f' switch prevents daemon initialization
1574 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1575 Barcellos for this patch.
1577 2005-11-04, Version 3.3.0 (Revision 216)
1578 * New modules have been added:
1579 - `serial', for monitoring traffic on the serial interfaces
1580 - `nfs', for graphing NFS procedure calls
1581 - `tape', traffic from/to tape devices
1582 * The memory.rrd now accepts more than 4Gig of memory.
1584 2005-10-26, Version 3.2.0 (Revision 200)
1585 * Support for graphing the processes has been added (thanks to Lyonel
1586 Vincent)
1587 * If reading from hddtemp fails collectd will increase the time
1588 between polls up to one day.
1589 * The init.d files have been improved.
1590 * Problems with the spec file have been fixed.
1592 2005-10-16, Version 3.1.0 (Revision 194)
1593 * Added the `setsid' syscall to the startup code.
1594 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1596 2005-09-30, Version 3.0.0 (Revision 184)
1597 * The ability to send/receive data to/from the network (think
1598 multicast) has been added.
1599 * Modules have been split up into shared libraries can be loaded at
1600 runtime. The biggest advantage is that the core program doesn't need
1601 to be linked against an external library.
1602 * A patch by George Kargiotakis has been applied: It fixes the sensors
1603 behaviour then more than one sensor is being queried.
1605 2005-09-16, Version 2.1.0 (Revision 172)
1606 * A module for swap statistics has been added.
1608 2005-09-09, Version 2.0.0 (Revision 135)
1609 * Filenames can no longer be configured at program startup. The only
1610 options as of this version are the directory and ping hosts.
1611 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1612 Soft-IRQ statistics are added to `System'.
1613 * Diskstats now collect read and write bytes, not sectors.
1614 * Ping statistics can now be collected for more than one host. There
1615 is no default any more: If no host is given no host will be pinged.
1616 * A self-written patch for libping has been applied so it builds
1617 cleanly.
1619 2005-09-01, Version 1.8.1 (Revision 123)
1620 * Much improved configure-script: libraries and features may now be
1621 disabled.
1622 * More detailed warnings/error messages when RRD update fails.
1624 2005-08-29, Version 1.8.0:
1625 * Support for collecting disk statistics under Solaris.
1627 2005-08-25, Version 1.7.0:
1628 * Support for libstatgrab[1] for load, memory usage and network
1629 traffic. CPU- and disk-usage are not (yet) supported, since
1630 libstatgrab returns insufficient information. I will contact the
1631 authors.
1632 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1633 aren't necessarily counted linear which is now handled correctly.
1634 [1]: http://www.i-scream.org/libstatgrab/
1636 2005-08-21, Version 1.6.0:
1637 * Basic support for Solaris: System load and cpu-usage can be
1638 collected under Solaris, too. Other stats will follow later.
1639 * Many fixes in the autoconf-script
1640 * Collection/Museum scripts have been added under contrib/museum
1641 * collectd may now be started in unprivileged mode, though ping
1642 statistics will not work.
1644 2005-07-17, Version 1.5.1:
1645 * Diskstats-RRDs now use major/minor for naming. Some systems have
1646 weird strings as disk-names..
1648 2005-07-17, Version 1.5:
1649 * A new module, diskstats, has been added. It collects information
1650 about the disks and partitions.
1652 2005-07-11, Version 1.4.2:
1653 * The meminfo module has been changed to work with more platforms
1654 and/or kernel versions.
1656 2005-07-10, Version 1.4.1: Correct traffic stats
1657 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1658 forgot to correct when I changed that module.
1660 2005-07-09, Version 1.4: More traffic stats
1661 * Traffic is now collected for all interfaces that can be found
1662 * Temperature-statistics are read from lm-sensors if available
1664 2005-07-08, Version 1.3: CPU stats
1665 * Collecting CPU statistics now
1667 2005-07-12, Version 1.2: Using syslog
1668 * collectd is now using the syslog facility to report errors, warnings
1669 and the like..
1670 * The default directory is now /var/db/collectd
1672 2005-07-10, Version 1.1: Minor changes
1673 * Nothing really useful to say ;)
1675 2005-07-09, Version 1.0: Initial Version
1676 * The following modules are provided:
1677 * Load average
1678 * Ping time
1679 * Traffic
1680 * Memory info
