494 installed in a non-standard path. Thanks to Dusty Doris for
496 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
497 Solaris, in the configure script automatically.
498 * build system, tcpconns plugin: Check for `kvm_nlist' and
499 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
500 library with similar functions to the BSD variant, but doesn't
501 provide these necessary functions.
502 * collectd.conf(5): Various fixes and clarifications.
503 * collectd: Remove a GNUism (unnamed unions), thus improving
505 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
506 This solves portability problems, especially for Solaris.
507 * dns plugin: Fix a portability problem with NetBSD.
508 * filecount plugin: Fix an off-by-one error. This error may cause a
510 * network plugin: Fix the handling of `type' in the network protocol.
511 Due to a programming mistake, only 4 or 8 bytes would be copied to a
512 much larger buffer. This caused the `type' to be transferred much
513 more often than necessary. In some cases, e. g. the `cpu' and
514 `cpufreq' plugins being used at the same time, data may be corrupted
515 in those files. Thanks to Bruno Prémont for debugging and reporting
517 * processes plugin: Fix a possible segmentation fault when specifying
518 invalid configuration options.
519 * unixsock plugin: Make sure the initialization function is run only
520 once. This resolves a file descriptor leak under systems which run
521 the initialization more than once, such as Solaris.
523 2008-10-16, Version 4.5.1
524 * build system: Change `--enable-<plugin>' to abort with an error if
525 dependencies are not met. Thanks to Bruno Prémont for the patch.
526 Also, the poisoning of various string functions has been restricted
528 * collectd: Fix a memory leak in the global value cache. With every
529 *missing* value a couple of bytes would be leaked. Another memory
530 leak in the configuration handling code has been fixed. Thanks to
531 Niraj Tolia for reporting these issues.
532 * collectd: Fix an off-by-one error in the ignorelist functionality.
533 When using regular expressions, the last character would be missing,
534 possibly matching differently from what one would expect.
535 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
537 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
538 Linzberger for reporting the bug.
539 * iptables plugin: Fix an off-by-one error. If a string was just one
540 character too long, it was truncated instead of reporting an error.
541 * network plugin: Fix a memory leak in the configuration handling
542 code. Thanks to Niraj Tolia for reporting this issue.
543 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
544 * postgresql plugin: Don't reopen connection during reinitialization.
545 This fixes a bug under Solaris and potentially other platforms.
546 Missing calls to `PQclear' have been added, too. This fixes memory
547 leaks. Thanks to ``Admin'' for reporting these bugs.
548 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
550 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
551 problems with some `libc's. Thanks to Matthias Lay for reporting the
554 2008-09-04, Version 4.5.0
555 * collectd: Added the ability to flush certain identifiers.
556 * collectd: The concept of `notification meta data' has been
558 * filecount plugin: The new filecount plugin counts the number of
559 files in a directory and its subdirectories.
560 * ipmi plugin: Sensor names have been changed to ensure unique names.
561 Notifications upon added and removed sensors can now be generated.
562 * notify_desktop plugin: This new plugin sends notifications to the
563 X desktop using the structure defined in the `Desktop Notification
565 * notify_email plugin: This new plugin sends out notifications via
566 email, using the `esmtp' library.
567 * onewire plugin: The new experimental(!) onewire plugin reads values,
568 such as temperatures, from sensors connected to the computer via the
570 * perl plugin: Improved synchronized access to internal data structures
571 and fixed a possible dead-lock.
572 * perl plugin: Added the ability to flush certain identifiers and marked
573 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
575 * perl plugin: Added the ability to configure Perl plugins.
576 * postgresql plugin: The new postgresql plugin collects statistics
577 about or from a PostgreSQL database.
578 * processes plugin: The `ProcessMatch' option has been added.
579 * rrdtool plugin: Implement throttling of the `update queue' to lessen
581 * tcpconns plugin: This plugin has been ported to OpenBSD.
582 * thermal plugin: The new thermal plugin collects system temperatures
583 using Linux ACPI thermal zone data.
585 2009-01-02, Version 4.4.5
586 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
587 file may be in both locations, especially when the database was
588 installed in a non-standard path. Thanks to Dusty Doris for
590 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
591 Solaris, in the configure script automatically.
592 * collectd.conf(5): Various fixes and clarifications.
593 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
594 portability problems, especially for Solaris.
595 * dns plugin: Fix a portability problem with NetBSD.
596 * network plugin: Fix the handling of `type' in the network protocol.
597 Due to a programming mistake, only 4 or 8 bytes would be copied to a
598 much larger buffer. This caused the `type' to be transferred much
599 more often than necessary. In some cases, e. g. the `cpu' and
600 `cpufreq' plugins being used at the same time, data may be corrupted
601 in those files. Thanks to Bruno Prémont for debugging and reporting
603 * unixsock plugin: Make sure the initialization function is run only
604 once. This resolves a file descriptor leak under systems which run
605 the initialization more than once, such as Solaris.
607 2008-10-16, Version 4.4.4
608 * build system: Change `--enable-<plugin>' to abort with an error if
609 dependencies are not met. Thanks to Bruno Prémont for the patch.
610 Also, the poisoning of various string functions has been restricted
612 * collectd: Fix a memory leak in the global value cache. With every
613 *missing* value a couple of bytes would be leaked. Another memory
614 leak in the configuration handling code has been fixed. Thanks to
615 Niraj Tolia for reporting these issues.
616 * collectd: Fix an off-by-one error in the ignorelist functionality.
617 When using regular expressions, the last character would be missing,
618 possibly matching differently from what one would expect.
619 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
621 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
622 Linzberger for reporting the bug.
623 * network plugin: Fix a memory leak in the configuration handling
624 code. Thanks to Niraj Tolia for reporting this issue.
625 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
626 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
627 problems with some `libc's. Thanks to Matthias Lay for reporting the
630 2008-09-01, Version 4.4.3
631 * collectd: Fix a memory leak in the threshold checking code.
632 * memcached plugin: Fix a too short timeout and a related file

637 2008-07-15, Version 4.4.2
638 * build system: Use pkg-config to detect the upsclient library.
639 * collectd: Try even harder to determine the endianess of the
640 architecture collectd is being built on.
641 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
643 * dns plugin: Fix compilation errors with BIND versions 19991001
645 * network plugin: Bugfix in the init routine: The init function
646 cleared a buffer regardless of its contents. This could lead to lost
647 values under Solaris.
648 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
649 * vserver plugin: Remove usage of the thread-unsafe `readdir'
651 * wireless plugin: Work around incorrect noise and power values
652 returned by some broken drivers.
654 2008-06-03, Version 4.4.1
655 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
656 to kyrone for reporting this.
657 * collectd: Fixed min/max output in notifications generated by
659 * collectd-nagios: Fix the protocol used to communicate with the
661 * perl plugin: Fail noisily, but don't shutdown the daemon, if
662 initialization has errors. An issue with Perl 5.10 has been fixed.
663 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
664 René Rebe and Siegmund Gorr for reporting this.
666 2008-05-06, Version 4.4.0
667 * collectd: Internal code cleanups.
668 * collectd: Added support for a `Flush' command in the unixsock and
669 exec plugins. This command can be used to force a plugin (or all) to
670 flush its values to disk.
671 * collectd: Thresholds can now be configured to apply to one data
672 source only, making it possible to configure different thresholds
673 for each data source.
674 * apache, nginx plugins: Added the possibility to disable host and/or
676 * ascent plugin: The new ascent plugin reads and parses the statistics
677 page of an Ascent server.
678 * cpu plugin: Support for the statgrab library has been added.
679 * disk plugin: The possibility to ignore certain disks or collect only
680 specific disks has been added.
681 * disk plugin: Support for the statgrab library has been added.
682 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
683 sensor values via IPMI, the intelligent platform management
685 * iptables plugin: The iptc library that is used by the iptables
686 plugin has been added to the distribution, because it is not
687 provided by all distributions and removed from at least one.
688 * powerdns plugin: The new powerdns plugin reads statistics from an
689 authoritative or a recursing PowerDNS name server.
690 * rrdtool plugin: The size of the files generated with the default
691 configuration has been decreased.
692 * tail plugin: The new tail plugin can be used to gather statistics by
693 continuously reading from log files.
694 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
695 TeamSpeak2 server and collects statistics about the number of users
696 and number of channels.
697 * users plugin: Support for the statgrab library has been added.
698 * vmem plugin: The new vmem plugin collects very detailed statistics
699 about the virtual memory subsystem of Linux.
701 2008-08-30, Version 4.3.4
702 * Build system: Improved detection of and linking with the statgrab
704 * collectd: Portability fixes, especially to determine endianess more
706 * Various plugins: Fix format strings.
707 * disk plugin: A fix for giving disks under Linux 2.4 the right names
708 again has been applied.
709 * memcached plugin: Fix a too short timeout and a related file
711 * memory plugin: A typo in the libstatgrab code has been fixed.
712 * network plugin: A fix in the initialization function solves problems
714 * nginx plugin: A thread-unsafe function has been replaced.
715 * vserver plugin: A thread-unsafe function has been replaced.
716 * wireless plugin: A work-around for broken wireless drivers has been
719 2008-04-22, Version 4.3.3
720 * build system: Improved detection of several libraries, especially if
721 they are in non-standard paths.
722 * build system: Portability fixes: Automatically define "_REENTRANT"
723 if the libc expects it.
724 * collectd: Error and warning messages have been improved.
725 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
727 * apache plugin: Allocate new memory when reading a webpage instead of
728 using a buffer of static size.
729 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
731 * hddtemp plugin: Error and warning messages have been improved.
732 * sensors plugin: Fix sensor collection for some chip types.
734 2008-03-29, Version 4.3.2
735 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
736 `Persist' threshold options.
737 * collectd: Fix handling of missing values in the global value cache.
738 * collectd: Improved error messages when parsing the configuration.

741 * wireless plugin: Fix reading noise value.
743 2008-03-05, Version 4.3.1
744 * exec plugin: Set supplementary group IDs.
746 + Use `memcpy' when constructing/parsing a package to avoid
747 alignment problems on weird architectures, such as Sparc.
748 + Translate doubles to/from the x86 byte representation to ensure
749 cross-platform compatibility.
750 * ping plugin: Correct the handling of the `TTL' setting.
751 * swap plugin: Reapply a patch for Solaris.
752 * tcpconns plugin: Portability improvements.
754 2008-02-18, Version 4.3.0
755 * collectd: Notifications have been added to the daemon. Notifications
756 are status messages that may be associated with a data instance.
757 * collectd: Threshold checking has been added to the daemon. This
758 means that you can configure threshold values for each data
759 instance. If this threshold is exceeded a notification will be
761 * collectd: The new `FQDNLookup' option tells the daemon to use the
762 full qualified domain name as the hostname, not just the host part
763 es returned by `gethostname(2)'.
764 * collectd: Support for more than one `TypesDB' file has been added.
765 This is useful when one such file is included in a package but one
766 wants to add custom type definitions.
767 * collectd: The `Include' config option has been expanded to handle
768 entire directories and shell wildcards.
769 * collectdmon: The new `collectdmon' binary detects when collectd
770 terminates and automatically restarts it again.
771 * csv plugin: The CSV plugin is now able to store counter values as a
772 rate, using the `StoreRates' configuration option.
773 * exec plugin: Handling of notifications has been added and the
774 ability to pass arguments to the executed programs has been added.
775 * hddtemp plugin: The new `TranslateDevicename' option lets you
776 disable the translation from device names to major-minor-numbers.
777 * logfile plugin: Handling of notifications has been added.
778 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
779 domain name lookups in this plugin.
780 * perl plugin: Many internal changes added support for handling multiple
781 threads making the plugin reasonably usable inside collectd. The API has
782 been extended to support notifications and export global variables to
783 Perl plugins; callbacks now have to be identified by name rather than a
784 pointer to a subroutine. The plugin is no longer experimental.
785 * uuid plugin: The new UUID plugin sets the hostname to an unique
786 identifier for this host. This is meant for setups where each client
787 may migrate to another physical host, possibly going through one or
788 more name changes in the process. Thanks to Richard Jones from
789 Red Hat's Emerging Technology group for this plugin.
790 * libvirt: The new libvirt plugin uses the `libvirt' library to query
791 CPU, disk and network statistics about guest systems on the same
792 physical server. Thanks to Richard Jones from Red Hat's Emerging
793 Technology group for this plugin.
795 2008-04-22, Version 4.2.7
796 * build system: Improved detection of several libraries, especially if
797 they are in non-standard paths.
798 * build system: Portability fixes: Automatically define "_REENTRANT"
799 if the libc expects it.
800 * collectd: Error and warning messages have been improved.
801 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
803 * apache plugin: Allocate new memory when reading a webpage instead of
804 using a buffer of static size.
805 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
807 * hddtemp plugin: Error and warning messages have been improved.
808 * sensors plugin: Fix sensor collection for some chip types.

812 * sensors plugin: Fix temperature collection with libsensors4.
813 * unixsock plugin: Fix mixed input and output operation on streams.
814 * wireless plugin: Fix reading noise value.
816 2008-03-04, Version 4.2.5
817 * apache plugin: Improved initialization and error messages.
818 * exec plugin: Set supplementary group IDs.
820 + Create separate threads for reading from the socket and parsing
821 and dispatching incoming packets. Versions prior to this may have
822 problems in high-load situations, where the socket receive buffers
823 overflows, resulting in gaps in the data.
824 + Use `memcpy' when constructing/parsing a package to avoid
825 alignment problems on weird architectures, such as Sparc.
826 + Translate doubles to/from the x86 byte representation to ensure
827 cross-platform compatibility.
828 * ping plugin: Correct the handling of the `TTL' setting.
829 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
830 * swap plugin: Reapply a patch for Solaris.
831 * tcpconns plugin: Portability improvements.
833 2008-01-21, Version 4.2.4
834 * unixsock plugin: A bug in the unixsock plugin caused it not to set
835 the permission on the socket as documented in the manpage. Thanks to
836 Evgeny Chukreev for fixing this issue.
837 * collectd: The documentation has been improved.
839 2007-12-28, Version 4.2.3
840 * sensors plugin: Updated the plugin to build and work with version 3
841 of the libsensors library.
843 2007-12-15, Version 4.2.2
844 * nginx plugin: Incorrect comparison of strings lead to a segfault
845 when using the plugin. Thanks to Saulius Grigaliunas for fixing
847 * logfile plugin: The config option `Timestamp' was handled
848 incorrectly and basically always active. Thanks to Luke Heberling
851 2007-11-08, Version 4.2.1
852 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
854 * snmp plugin: Fix a memory leak.
856 2007-10-27, Version 4.2.0
857 * collectd: The new config option `Include' lets you include other
858 configfiles and thus split up your config into smaller parts. This
859 may be especially interesting for the snmp plugin to keep the data
860 definitions separate from the host definitions.
861 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
862 (number of connections, octets and packets for each service and
863 destination). Thanks to Sebastian Harl for this plugin.
864 * memcached plugin: The new `memcached' plugin connects to a memcached
865 daemon process and collects statistics of this distributed caching
866 system. Thanks to Antony Dovgal for contributing this plugin.
867 * nginx plugin: The new `nginx' plugin reads the status page of an
868 nginx daemon and saves the handled connections and requests.
869 * perl plugin: Many changes, including the added `EnableDebugger'
870 config option which lets you debug your Perl plugins more easily.
871 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
872 be more thread-safe otherwise by locking calls to the library.
873 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
874 correct the values returned by SNMP-agents. If a <data> block is
875 defined as `table' the instance is now optional. The sequence number
876 is used as the type-instance in this case. The new `InstancePrefix'
877 option allows to add arbitrary prefixes to the type-instance.
878 * tcpconns plugin: The new `tcpconns' plugin collects the number of
879 certain TCP connections and what state they're in. This can be used
880 to see how many connections your FTP server has to handle or how
881 many outgoing connections your mailserver has open.
883 2008-01-11, Version 4.1.6
884 * unixsock plugin: A bug in the unixsock plugin caused it not to set
885 the permission on the socket as documented in the manpage. Thanks to
886 Evgeny Chukreev for fixing this issue.

897 it's in a non-standard location.
898 * Build system: A bug when parsing the argument for
899 `--with-libnetsnmp' has been fixed.
900 * collectd: Implement `strerror_r' if the libc doesn't provide it.
901 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
902 a deadlock or delay when shutting down the daemon.
903 * snmp plugin: Fix a memory leak.
905 2007-10-24, Version 4.1.3
906 * collectd: A build issue under Solaris has been resolved by renaming
908 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
909 be more thread-safe otherwise by locking calls to the library.
911 2007-09-28, Version 4.1.2
912 * apcups plugin: Fix reporting of the `load percent' data.
913 * wireless plugin: Correct the handling of cards returning signal and
914 noise quality as percentage.
915 * perl plugin: Fix a possible buffer overflow in get_module_name().
916 * build system: Further improve the detection of libraries.
917 * netlink plugin: Build issues under some older versions of the Linux
918 includes (i. e. Debian Sarge) have been fixed.
919 * snmp plugin: Fix a potential segfault when a host times out. Add
920 support for the `timeticks' type.
922 2007-09-12, Version 4.1.1
923 * Build system: The detection of `libnetlink' has been improved.
924 * collectd: The documentation has been fixed in numerous places.
925 * exec plugin: Setting the group under which to run a program has been
927 * collectd: The `sstrerror' function was improved to work correctly
928 with the broken GNU version of `strerror_r'.
929 * collectd: Write an error message to STDERR when loading of a plugin
931 * apcups plugin: Fix the `types' used to submit the values: They still
932 has an `apcups_' prefix which doesn't work anymore.
933 * rrdtool plugin: Create new RRD-files with the `begin' time set to
934 whatever the client thinks is `now'..
936 2007-09-01, Version 4.1.0
937 * Build system: The build system has been changed to automatically
938 disable all plugins, which are missing dependencies. The dependency
939 checking has been removed from the plugins themselves to remove
941 * Flexible interval: The interval of collected data is now sent along
942 with the data itself over the network, so that the interval-settings
943 of server and clients no longer needs to match.
944 * netlink plugin: The new `netlink' plugin connects to the Linux
945 kernel using a netlink socket and uses it to query information about
946 interfaces, qdiscs and classes.
947 * rrdtool plugin: The cache is now dumped to disk in an extra thread
948 to not block data collection.
949 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
950 network devices, such as switches, routers, thermometers, rack
951 monitoring servers, etc. The collectd-snmp(5) manpage documents this
953 * unixsock plugin: Added the `LISTVAL' command.
954 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
955 of music played with xmms.
957 2007-09-28, Version 4.0.9

959 * wireless plugin: Correct the handling of cards returning signal and
960 noise quality as percentage.
961 * perl plugin: Fix a possible buffer overflow in get_module_name().
963 2007-09-12, Version 4.0.8
964 * collectd: The `sstrerror' function was improved to work correctly
965 with the broken GNU version of `strerror_r'.
966 * collectd: Write an error message to STDERR when loading of a plugin
968 * apcups plugin: Fix the `types' used to submit the values: They still
969 has an `apcups_' prefix which doesn't work anymore.
970 * rrdtool plugin: Create new RRD-files with the `begin' time set to
971 whatever the client thinks is `now'..
973 2007-08-26, Version 4.0.7
974 * documentation: Some typos have been fixed and some information has
976 * build system: Many fixes for detecting libraries in unusual places,
977 such as on RedHat systems. The affected libraries are `libcurl',
978 `libmysql', and `libupsclient'.
979 * network plugin: Allow the `Port' option to be specified as a number
980 (i. e. without quotes).
981 * nut plugin: A fix allows linking the nut plugin against
982 libupsclient, version >= 2.2.0.
983 * processes plugin: Fix a potential segmentation fault.
985 2007-07-30, Version 4.0.6
986 * sensors plugin: Fix the ignorelist functionality: Only the `type
987 instance' was used to match against the list, but the documentation
988 told otherwise. This release fixes the code, so it complies with the
990 * syslog plugin: Call `openlog' right when the plugin is loaded, so
991 configuration messages will end up in the logging facility.
992 * conrtib/fedora: The contributed specfile for Fedora has been
995 2007-07-05, Version 4.0.5
996 * Portability: More fixes for OpenBSD have been included.
998 2007-06-24, Version 4.0.4
999 * cpu plugin: Fixed the Solaris code.
1000 * dns plugin: Fixed a build issue for OpenBSD.
1001 * interface plugin: Fixed the Solaris code.
1002 * load plugin: Fixed the alternative `/proc' Linux code.
1003 * memory plugin: Fixed the Solaris code.
1004 * oconfig: Don't require `-lfl' anymore.
1006 2007-06-19, Version 4.0.3
1007 * cpu plugin: Fix the Darwin / Mac OS X code.
1008 * ping plugin: Use the return value of `getpid', not its address.
1009 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
1010 initialized correctly.
1011 * configure: Added `--with-nan-emulation' to aid cross compilation.
1013 2007-06-12, Version 4.0.2
1014 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
1015 they're given in numerically form.
1017 2007-06-07, Version 4.0.1
1018 * iptables plugin: A bug in the configuration routine has been fixed.
1019 Setting a comment in the configfile will no longer cause a
1022 2007-06-03, Version 4.0.0
1023 * collectd: The plugin-infrastructure has been changed to allow for
1024 more types of plugins, namely `write' and `log' plugins.
1025 * collectd: The read-function has been changed to read many plugins in
1026 parallel, using threads. Thus, plugins generally need to use
1027 thread-safe functions from now on.
1028 * collectd: The '-t' command line options allows to perform syntax tests
1029 of the configuration file and exit immediately.
1030 * csv plugin: The new `csv' plugin handles output to `comma separated
1032 * rrdtool plugin: The new `rrdtool' plugin handles output to
1033 RRD-files. Data can be cached to combine multiple updates into one
1034 write to increase IO-performance.
1035 * network plugin: The new `network' plugin handles IO via the network.
1036 It implements a different, much more extensible protocol which can
1037 combine many values in one packet, decreasing the number of UDP-
1038 packets being sent. It can read from and send to the network and
1039 with the appropriate configuration even forward packets to other
1041 * unixsock plugin: The new `unixsock' plugin provides an interface to
1042 communicate with the daemon while it is running. Right now the
1043 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1045 * perl plugin: The new `perl' plugin allows you to write extensions
1046 for collectd in the scripting-language Perl.
1047 * logfile plugin: The new `logfile' plugin writes logmessages to files
1048 or STDOUT or STDERR.
1049 * syslog plugin: The new `syslog' plugin sends logmessages to the
1050 system's syslog daemon.
1051 * entropy plugin: The new `entropy' plugin collects the amount of
1052 entropy currently being available to the system.
1053 * exec plugin: The new `exec' plugin forks child processes and reads
1054 back values provided by the forked processes.
1055 * iptables plugin: The new `iptables' plugin reads counters from
1056 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1058 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1059 to Peter Holik for contributing this plugin.
1060 * nut plugin: The new `nut' plugin connects the upsd of the `network
1061 ups tools' and reads information about the connected UPS.
1062 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1063 connections) field was added by Florent Monbillard.
1064 * collectd-nagios: The new `collectd-nagios' binary queries values
1065 from collectd, parses them and exits according to Nagios-standards.
1066 * manpages: The manpages have been improved a lot.
1068 2007-09-28, Version 3.11.7
1069 * wireless plugin: Correct the handling of cards returning signal and
1070 noise quality as percentage.
1072 2007-08-31, Version 3.11.6
1073 * processes plugin: Fix a potential segmentation fault.
1075 2007-05-29, Version 3.11.5
1076 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1077 * ntpd plugin: Fix a potential buffer overflow.
1078 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1079 were accounted as `zombies'.
1081 2007-04-10, Version 3.11.4
1082 * dns plugin: Change the order of includes to make the plugin compile
1085 2007-03-30, Version 3.11.3
1086 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1087 of the unused `COLLECT_KSTAT'.
1089 2007-02-11, Version 3.11.2
1090 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1091 NULL-pointer may have been passed to `printf' which causes a
1092 segfault with some libcs.
1094 2007-02-10, Version 3.11.1
1095 * df plugin: Some wrong defines have been fixed so the plugin works
1096 under Solaris again.
1097 * dns plugin: The usage of a struct has been fixed to work with
1099 * processes plugin: Some missing defines have been added so the plugin
1100 compiles cleanly under FreeBSD and presumably other UNIXes.
1102 2006-12-22, Version 3.11.0
1103 * collectd: The new command line option `-P' makes it easier for
1104 distributors to change the location of PID-files.
1105 * collectd: The daemon shuts down faster now which makes it easier to
1106 write init.d-scripts for it.
1107 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1108 caused problems every now and then.
1109 * df plugin: New config options allow to ignore certain mountpoints,
1110 filesystem types or devices.
1111 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1112 and interprets it. It collects traffic as well as qtype, opcode and
1114 * email plugin: Sebastian Harl has contributed this plugin which
1115 counts received mails in categories (e. g. ham, spam, virus), spam
1116 score (as given by SpamAssassin) and check types.
1117 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1118 uses `mbmon' to gather information from sensors on the motherboard.
1119 * processes plugin: Collect detailed statistics for configured
1120 processes, that's process and thread count, CPU usage, resident
1121 segment size and pagefaults.
1122 * multimeter plugin: Peter Holik contributed a new plugin which
1123 queries multimeters.
1124 * sensors plugin: Lubos Stanek has put much effort into improving this
1125 plugin, including `extended naming', collection of voltage values
1126 and the possibility to ignore certain values.
1128 2006-12-21, Version 3.10.4
1129 * Max Kellermann has identified a bug in the server routine: When
1130 opening a socket fails the daemon will (re)try opening the socket in
1131 an endless loop, ultimately leading to a `EMFILE' error.
1133 2006-11-04, Version 3.10.3
1134 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1135 ntpd's reply was sent in more than one packet, the buffer size was
1136 calculated incorrectly, resulting in the reading of uninitialized or
1139 2006-11-01, Version 3.10.2
1140 * The sample config file has been improved.
1141 * Errors in the manpages have been corrected.
1142 * The ping-plugin now adds hosts during initialization, not during
1143 startup. This speeds up startup when no network connectivity is
1144 available. Also, the hosts are being added later when the network is
1146 * Improved BSD-support for the df-plugin.
1147 * Fixed syntax errors in the swap-plugin for Mac OS X.
1148 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1150 * Don't disable the mysql-plugin if connecting to the database fails
1151 during initialization. Instead, try again in increasing intervals.
1153 2006-07-19, Version 3.10.1
1154 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1155 the apcups cannot be reached, unconnected sockets will pile up and
1156 eventually lead to `Too many open files' errors.
1158 2006-07-09, Version 3.10.0
1159 * The `disk' plugin has been ported to Darwin.
1160 * The `battery' plugin should work on many Apple computers now.
1161 * The `traffic' plugin can now ignore certain interfaces. Also,
1162 statistics for sent/received packets and errors have been added.
1163 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1164 to Anthony Gialluca for contributing this plugin and providing me
1165 with a test environment :)
1166 * A plugin for monitoring an NTP instance and the local clock drift
1169 2006-06-25, Version 3.9.4
1170 * The Solaris code in the `swap' plugin has been changed to reflect
1171 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1173 * The debugging system has been fixed to work with the Sun libc.
1174 * When built without librrd the variable `operating_mode' could be
1175 uninitialized. Thanks to David Elliot for reporting the bug.
1177 2006-06-01, Version 3.9.3
1178 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1179 operating systems also profit from the changes, but I wasn't able to
1181 * Changed the build system to find the netinet-includes under FreeBSD
1182 and therefore successfully build the `liboping' library there.
1184 2006-05-09, Version 3.9.2
1185 * Applied a patch to the `liboping' library. Due to a bug in the
1186 sequence checking the `ping' plugin stopped working after
1187 approximately 7.6 days.
1189 2006-05-09, Version 3.8.5
1190 * Applied a patch to the `liboping' library. Due to a bug in the
1191 sequence checking the `ping' plugin stopped working after
1192 approximately 7.6 days.
1194 2006-04-21, Version 3.9.1
1195 * Build issues with Solaris and possible other architectures have been
1197 * Problems when building the `apache'-plugin without `libcurl' have
1199 * A bug in the `ping' plugin has been fixed. Sorry folks.
1201 2006-04-02, Version 3.9.0
1202 * A plugin to monitor the Apache webserver has been added.
1203 <http://httpd.apache.org/>
1204 * A plugin to collect statistics about virtual servers using VServer.
1205 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1207 * A plugin for wireless LAN cards has been added. It monitors signal
1208 strength, link quality and noise ratio..
1209 * A plugin for Apple hardware sensors has been added.
1210 * An option to compile collectd with different `step' and `heartbeat'
1211 settings has been added. The size of RRAs is no longer static but
1212 calculated based on the settings for `step' and `width'.
1213 * The `ping' plugin can now be configured to use a certain TTL.
1214 * A plugin to monitor the hardware sensors of Apple computers has been
1216 * The plugins `cpu', `memory', `processes' and `traffic' have been
1217 ported to Mach/Darwin (Mac OS X).
1218 * The `log mode' has been contributed by Christophe Kalt. It writes
1219 the data into text files rather than RRD files.
1221 2006-04-09, Version 3.8.4
1222 * Applied patch by Vincent Stehlé which improves the disk-name
1223 resolution in the `hddtemp' plugin for Linux systems.
1225 2006-04-02, Version 3.8.3
1226 * Applied a patch by James Byers: The MySQL plugin was not working
1227 with MySQL 5.0.2 or later.
1229 2006-03-14, Version 3.8.2
1230 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1231 the GNU libc, because it points to `/etc/fstab' rather than
1234 2006-03-13, Version 3.8.1
1235 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1236 * Fixes in the debian `postinst' and `init.d' scripts.
1238 2006-03-09, Version 3.8.0
1239 * The `ping' plugin no longer uses `libping' but a self written
1240 library named `liboping'. With this library it's possible to ping
1241 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1243 2006-02-18, Version 3.7.2
1244 * A simple bug in the `battery' plugin has been fixed. It should now
1245 work with ACPI based batteries as well. Thanks to Sebastian for
1247 * Fixing a bug that prevented collectd to be built without librrd.
1248 Thanks to Werner Heuser for reporting it.
1250 2006-02-04, Version 3.7.1
1251 * The new network code has been improved to build with older versions
1253 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1254 to Tommie Gannert for this patch.
1256 2006-01-30, Version 3.7.0
1257 * The `battery' plugin has been added. It collects information about
1259 * The MySQL plugin has been improved: It now writes two more RRD
1260 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1261 * The `cpufreq' plugin now reads another file since the file it did
1262 read so far causes much overhead in the kernel. Also, you need root
1263 to read the old file, but not to read the new one.
1264 * The `hddtemp' plugin can now be configured to connect to another
1265 address and/or port than localhost.
1266 * The `df' plugin now prefers `statvfs' over `statfs'.
1267 * The network code has been rewritten. collectd now supports unicast
1268 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1269 be set in the configfile.
1271 2006-01-24, Version 3.6.2
1272 * Due to a bug in the configfile handling collectd wouldn't start in
1273 client mode. This released fixes this.
1275 2006-01-20, Version 3.6.1
1276 * Due to a bug in `configure.in' all modules and the binary were
1277 linked against `libmysqlclient'. This issue is solved by this
1280 2006-01-17, Version 3.6.0
1281 * A config file has been added. This allows for loading only specific
1283 * A `df' plugin has been added.
1284 * A `mysql' plugin has been added.
1285 * The `ping' plugin doesn't entirely give up hope when a socket error
1286 occurred, but will back of and increase the intervals between tries.
1288 2006-01-21, Version 3.5.2
1289 * Fixed yet another bug in the signal handling.. Stupid typo..
1290 * Improved the ping plugin to not give up on socket errors (backport
1293 2005-12-18, Version 3.5.1
1294 * The PID-file is now deleted correctly when shutting down the daemon.
1295 * SIGINT and SIGTERM are now handled correctly.
1297 2005-12-16, Version 3.5.0 (Revision 326)
1298 * A bug in the `load' module under Solaris has been fixed.
1299 * The `users' module has been contributed by Sebastian Harl. It counts
1300 currently logged in users.
1301 * The CPU module now works under FreeBSD without the use of
1302 `libstatgrab', however SMP support is missing.
1303 * The default directories for the RRD files and the PID file now
1304 depend on the compile time setting of `localstatedir'.
1306 2005-11-15, Version 3.4.0 (Revision 236)
1307 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1308 from gentoo's bugzilla for writing the patch.
1309 * The build dependency for librrd has been removed. Binaries built
1310 without librrd are client-only and will multicast their value as
1311 with the `-c' argument.
1312 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1313 * The newly introduced `-f' switch prevents daemon initialization
1314 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1315 Barcellos for this patch.
1317 2005-11-04, Version 3.3.0 (Revision 216)
1318 * New modules have been added:
1319 - `serial', for monitoring traffic on the serial interfaces
1320 - `nfs', for graphing NFS procedure calls
1321 - `tape', traffic from/to tape devices
1322 * The memory.rrd now accepts more than 4Gig of memory.
1324 2005-10-26, Version 3.2.0 (Revision 200)
1325 * Support for graphing the processes has been added (thanks to Lyonel
1327 * If reading from hddtemp fails collectd will increase the time
1328 between polls up to one day.
1329 * The init.d files have been improved.
1330 * Problems with the spec file have been fixed.
1332 2005-10-16, Version 3.1.0 (Revision 194)
1333 * Added the `setsid' syscall to the startup code.
1334 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1336 2005-09-30, Version 3.0.0 (Revision 184)
1337 * The ability to send/receive data to/from the network (think
1338 multicast) has been added.
1339 * Modules have been split up into shared libraries can be loaded at
1340 runtime. The biggest advantage is that the core program doesn't need
1341 to be linked against an external library.
1342 * A patch by George Kargiotakis has been applied: It fixes the sensors
1343 behaviour then more than one sensor is being queried.
1345 2005-09-16, Version 2.1.0 (Revision 172)
1346 * A module for swap statistics has been added.
1348 2005-09-09, Version 2.0.0 (Revision 135)
1349 * Filenames can no longer be configured at program startup. The only
1350 options as of this version are the directory and ping hosts.
1351 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1352 Soft-IRQ statistics are added to `System'.
1353 * Diskstats now collect read and write bytes, not sectors.
1354 * Ping statistics can now be collected for more than one host. There
1355 is no default any more: If no host is given no host will be pinged.
1356 * A self-written patch for libping has been applied so it builds
1359 2005-09-01, Version 1.8.1 (Revision 123)
1360 * Much improved configure-script: libraries and features may now be
1362 * More detailed warnings/error messages when RRD update fails.
1364 2005-08-29, Version 1.8.0:
1365 * Support for collecting disk statistics under Solaris.
1367 2005-08-25, Version 1.7.0:
1368 * Support for libstatgrab[1] for load, memory usage and network
1369 traffic. CPU- and disk-usage are not (yet) supported, since
1370 libstatgrab returns insufficient information. I will contact the
1372 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1373 aren't necessarily counted linear which is now handled correctly.
1374 [1]: http://www.i-scream.org/libstatgrab/
1376 2005-08-21, Version 1.6.0:
1377 * Basic support for Solaris: System load and cpu-usage can be
1378 collected under Solaris, too. Other stats will follow later.
1379 * Many fixes in the autoconf-script
1380 * Collection/Museum scripts have been added under contrib/museum
1381 * collectd may now be started in unprivileged mode, though ping
1382 statistics will not work.
1384 2005-07-17, Version 1.5.1:
1385 * Diskstats-RRDs now use major/minor for naming. Some systems have
1386 weird strings as disk-names..
1388 2005-07-17, Version 1.5:
1389 * A new module, diskstats, has been added. It collects information
1390 about the disks and partitions.
1392 2005-07-11, Version 1.4.2:
1393 * The meminfo module has been changed to work with more platforms
1394 and/or kernel versions.
1396 2005-07-10, Version 1.4.1: Correct traffic stats
1397 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1398 forgot to correct when I changed that module.
1400 2005-07-09, Version 1.4: More traffic stats
1401 * Traffic is now collected for all interfaces that can be found
1402 * Temperature-statistics are read from lm-sensors if available
1404 2005-07-08, Version 1.3: CPU stats
1405 * Collecting CPU statistics now
1407 2005-07-12, Version 1.2: Using syslog
1408 * collectd is now using the syslog facility to report errors, warnings
1410 * The default directory is now /var/db/collectd
1412 2005-07-10, Version 1.1: Minor changes
1413 * Nothing really useful to say ;)
1415 2005-07-09, Version 1.0: Initial Version
1416 * The following modules are provided:
projects / collectd.git / blob
