216 it. It is similar to the already existing PostgreSQL plugin but uses
217 libdbi to communicate with the database(s).
218 * interface plugin: Use the ignorelist framework when selecting /
219 ignoring interfaces. This allows one to use regular expressions to
220 select interfaces, too.

306 * network plugin: Fix the handling of `type' in the network protocol.
307 Due to a programming mistake, only 4 or 8 bytes would be copied to a
308 much larger buffer. This caused the `type' to be transferred much
309 more often than necessary. In some cases, e. g. the `cpu' and
310 `cpufreq' plugins being used at the same time, data may be corrupted
311 in those files. Thanks to Bruno Prémont for debugging and reporting
313 * processes plugin: Fix a possible segmentation fault when specifying
314 invalid configuration options.
315 * unixsock plugin: Make sure the initialization function is run only

511 * vserver plugin: A thread-unsafe function has been replaced.
512 * wireless plugin: A work-around for broken wireless drivers has been
515 2008-04-22, Version 4.3.3
516 * build system: Improved detection of several libraries, especially if
517 they are in non-standard paths.
518 * build system: Portability fixes: Automatically define "_REENTRANT"
519 if the libc expects it.
520 * collectd: Error and warning messages have been improved.
521 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
523 * apache plugin: Allocate new memory when reading a webpage instead of
524 using a buffer of static size.
525 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
527 * hddtemp plugin: Error and warning messages have been improved.
528 * sensors plugin: Fix sensor collection for some chip types.
530 2008-03-29, Version 4.3.2
531 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
532 `Persist' threshold options.
533 * collectd: Fix handling of missing values in the global value cache.
534 * collectd: Improved error messages when parsing the configuration.
535 * sensors plugin: Fix temperature collection with libsensors4.
536 * unixsock plugin: Fix mixed input and output operation on streams.
537 * wireless plugin: Fix reading noise value.
539 2008-03-05, Version 4.3.1
540 * exec plugin: Set supplementary group IDs.
542 + Use `memcpy' when constructing/parsing a package to avoid
543 alignment problems on weird architectures, such as Sparc.
544 + Translate doubles to/from the x86 byte representation to ensure
545 cross-platform compatibility.
546 * ping plugin: Correct the handling of the `TTL' setting.
547 * swap plugin: Reapply a patch for Solaris.
548 * tcpconns plugin: Portability improvements.
550 2008-02-18, Version 4.3.0
551 * collectd: Notifications have been added to the daemon. Notifications
552 are status messages that may be associated with a data instance.
553 * collectd: Threshold checking has been added to the daemon. This
554 means that you can configure threshold values for each data
555 instance. If this threshold is exceeded a notification will be
557 * collectd: The new `FQDNLookup' option tells the daemon to use the
558 full qualified domain name as the hostname, not just the host part
559 es returned by `gethostname(2)'.
560 * collectd: Support for more than one `TypesDB' file has been added.
561 This is useful when one such file is included in a package but one
562 wants to add custom type definitions.
563 * collectd: The `Include' config option has been expanded to handle
564 entire directories and shell wildcards.
565 * collectdmon: The new `collectdmon' binary detects when collectd
566 terminates and automatically restarts it again.
567 * csv plugin: The CSV plugin is now able to store counter values as a
568 rate, using the `StoreRates' configuration option.
569 * exec plugin: Handling of notifications has been added and the
570 ability to pass arguments to the executed programs has been added.
571 * hddtemp plugin: The new `TranslateDevicename' option lets you
572 disable the translation from device names to major-minor-numbers.
573 * logfile plugin: Handling of notifications has been added.
574 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
575 domain name lookups in this plugin.
576 * perl plugin: Many internal changes added support for handling multiple
577 threads making the plugin reasonably usable inside collectd. The API has
578 been extended to support notifications and export global variables to
579 Perl plugins; callbacks now have to be identified by name rather than a
580 pointer to a subroutine. The plugin is no longer experimental.
581 * uuid plugin: The new UUID plugin sets the hostname to an unique
582 identifier for this host. This is meant for setups where each client
583 may migrate to another physical host, possibly going through one or
584 more name changes in the process. Thanks to Richard Jones from
585 Red Hat's Emerging Technology group for this plugin.
586 * libvirt: The new libvirt plugin uses the `libvirt' library to query
587 CPU, disk and network statistics about guest systems on the same
588 physical server. Thanks to Richard Jones from Red Hat's Emerging
589 Technology group for this plugin.
591 2008-04-22, Version 4.2.7
592 * build system: Improved detection of several libraries, especially if
593 they are in non-standard paths.
594 * build system: Portability fixes: Automatically define "_REENTRANT"
595 if the libc expects it.
596 * collectd: Error and warning messages have been improved.
597 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
599 * apache plugin: Allocate new memory when reading a webpage instead of
600 using a buffer of static size.
601 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
603 * hddtemp plugin: Error and warning messages have been improved.
604 * sensors plugin: Fix sensor collection for some chip types.
606 2008-03-29, Version 4.2.6
607 * collectd: Improved error messages when parsing the configuration.
608 * sensors plugin: Fix temperature collection with libsensors4.
609 * unixsock plugin: Fix mixed input and output operation on streams.
610 * wireless plugin: Fix reading noise value.
612 2008-03-04, Version 4.2.5
613 * apache plugin: Improved initialization and error messages.
614 * exec plugin: Set supplementary group IDs.
616 + Create separate threads for reading from the socket and parsing
617 and dispatching incoming packets. Versions prior to this may have
618 problems in high-load situations, where the socket receive buffers
619 overflows, resulting in gaps in the data.
620 + Use `memcpy' when constructing/parsing a package to avoid
621 alignment problems on weird architectures, such as Sparc.
622 + Translate doubles to/from the x86 byte representation to ensure
623 cross-platform compatibility.
624 * ping plugin: Correct the handling of the `TTL' setting.
625 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
626 * swap plugin: Reapply a patch for Solaris.
627 * tcpconns plugin: Portability improvements.
629 2008-01-21, Version 4.2.4
630 * unixsock plugin: A bug in the unixsock plugin caused it not to set
631 the permission on the socket as documented in the manpage. Thanks to
632 Evgeny Chukreev for fixing this issue.
633 * collectd: The documentation has been improved.
635 2007-12-28, Version 4.2.3
636 * sensors plugin: Updated the plugin to build and work with version 3
637 of the libsensors library.
639 2007-12-15, Version 4.2.2
640 * nginx plugin: Incorrect comparison of strings lead to a segfault
641 when using the plugin. Thanks to Saulius Grigaliunas for fixing
643 * logfile plugin: The config option `Timestamp' was handled
644 incorrectly and basically always active. Thanks to Luke Heberling
647 2007-11-08, Version 4.2.1
648 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
650 * snmp plugin: Fix a memory leak.
652 2007-10-27, Version 4.2.0
653 * collectd: The new config option `Include' lets you include other
654 configfiles and thus split up your config into smaller parts. This
655 may be especially interesting for the snmp plugin to keep the data
656 definitions separate from the host definitions.
657 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
658 (number of connections, octets and packets for each service and
659 destination). Thanks to Sebastian Harl for this plugin.
660 * memcached plugin: The new `memcached' plugin connects to a memcached
661 daemon process and collects statistics of this distributed caching
662 system. Thanks to Antony Dovgal for contributing this plugin.
663 * nginx plugin: The new `nginx' plugin reads the status page of an
664 nginx daemon and saves the handled connections and requests.
665 * perl plugin: Many changes, including the added `EnableDebugger'
666 config option which lets you debug your Perl plugins more easily.
667 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
668 be more thread-safe otherwise by locking calls to the library.
669 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
670 correct the values returned by SNMP-agents. If a <data> block is
671 defined as `table' the instance is now optional. The sequence number
672 is used as the type-instance in this case. The new `InstancePrefix'
673 option allows to add arbitrary prefixes to the type-instance.
674 * tcpconns plugin: The new `tcpconns' plugin collects the number of
675 certain TCP connections and what state they're in. This can be used
676 to see how many connections your FTP server has to handle or how
677 many outgoing connections your mailserver has open.
679 2008-01-11, Version 4.1.6
680 * unixsock plugin: A bug in the unixsock plugin caused it not to set
681 the permission on the socket as documented in the manpage. Thanks to
682 Evgeny Chukreev for fixing this issue.
683 * collectd: The documentation has been improved.
685 2007-12-27, Version 4.1.5

693 it's in a non-standard location.
694 * Build system: A bug when parsing the argument for
695 `--with-libnetsnmp' has been fixed.
696 * collectd: Implement `strerror_r' if the libc doesn't provide it.
697 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
698 a deadlock or delay when shutting down the daemon.
699 * snmp plugin: Fix a memory leak.
701 2007-10-24, Version 4.1.3
702 * collectd: A build issue under Solaris has been resolved by renaming
704 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
705 be more thread-safe otherwise by locking calls to the library.
707 2007-09-28, Version 4.1.2
708 * apcups plugin: Fix reporting of the `load percent' data.
709 * wireless plugin: Correct the handling of cards returning signal and
710 noise quality as percentage.

719 * Build system: The detection of `libnetlink' has been improved.
720 * collectd: The documentation has been fixed in numerous places.
721 * exec plugin: Setting the group under which to run a program has been
723 * collectd: The `sstrerror' function was improved to work correctly
724 with the broken GNU version of `strerror_r'.
725 * collectd: Write an error message to STDERR when loading of a plugin
727 * apcups plugin: Fix the `types' used to submit the values: They still
728 has an `apcups_' prefix which doesn't work anymore.
729 * rrdtool plugin: Create new RRD-files with the `begin' time set to
730 whatever the client thinks is `now'..
732 2007-09-01, Version 4.1.0
733 * Build system: The build system has been changed to automatically
734 disable all plugins, which are missing dependencies. The dependency
735 checking has been removed from the plugins themselves to remove
737 * Flexible interval: The interval of collected data is now sent along
738 with the data itself over the network, so that the interval-settings
739 of server and clients no longer needs to match.
740 * netlink plugin: The new `netlink' plugin connects to the Linux
741 kernel using a netlink socket and uses it to query information about
742 interfaces, qdiscs and classes.
743 * rrdtool plugin: The cache is now dumped to disk in an extra thread
744 to not block data collection.
745 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
746 network devices, such as switches, routers, thermometers, rack
747 monitoring servers, etc. The collectd-snmp(5) manpage documents this
749 * unixsock plugin: Added the `LISTVAL' command.
750 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
751 of music played with xmms.
753 2007-09-28, Version 4.0.9
754 * apcups plugin: Fix reporting of the `load percent' data.
755 * wireless plugin: Correct the handling of cards returning signal and
756 noise quality as percentage.
757 * perl plugin: Fix a possible buffer overflow in get_module_name().
759 2007-09-12, Version 4.0.8
760 * collectd: The `sstrerror' function was improved to work correctly
761 with the broken GNU version of `strerror_r'.
762 * collectd: Write an error message to STDERR when loading of a plugin
764 * apcups plugin: Fix the `types' used to submit the values: They still
765 has an `apcups_' prefix which doesn't work anymore.
766 * rrdtool plugin: Create new RRD-files with the `begin' time set to
767 whatever the client thinks is `now'..
769 2007-08-26, Version 4.0.7
770 * documentation: Some typos have been fixed and some information has
772 * build system: Many fixes for detecting libraries in unusual places,
773 such as on RedHat systems. The affected libraries are `libcurl',
774 `libmysql', and `libupsclient'.
775 * network plugin: Allow the `Port' option to be specified as a number
776 (i. e. without quotes).
777 * nut plugin: A fix allows linking the nut plugin against
778 libupsclient, version >= 2.2.0.
779 * processes plugin: Fix a potential segmentation fault.
781 2007-07-30, Version 4.0.6
782 * sensors plugin: Fix the ignorelist functionality: Only the `type
783 instance' was used to match against the list, but the documentation
784 told otherwise. This release fixes the code, so it complies with the
786 * syslog plugin: Call `openlog' right when the plugin is loaded, so
787 configuration messages will end up in the logging facility.
788 * conrtib/fedora: The contributed specfile for Fedora has been
791 2007-07-05, Version 4.0.5
792 * Portability: More fixes for OpenBSD have been included.
794 2007-06-24, Version 4.0.4
795 * cpu plugin: Fixed the Solaris code.
796 * dns plugin: Fixed a build issue for OpenBSD.

811 they're given in numerically form.
813 2007-06-07, Version 4.0.1
814 * iptables plugin: A bug in the configuration routine has been fixed.
815 Setting a comment in the configfile will no longer cause a
818 2007-06-03, Version 4.0.0
819 * collectd: The plugin-infrastructure has been changed to allow for
820 more types of plugins, namely `write' and `log' plugins.
821 * collectd: The read-function has been changed to read many plugins in
822 parallel, using threads. Thus, plugins generally need to use
823 thread-safe functions from now on.
824 * collectd: The '-t' command line options allows to perform syntax tests
825 of the configuration file and exit immediately.
826 * csv plugin: The new `csv' plugin handles output to `comma separated
828 * rrdtool plugin: The new `rrdtool' plugin handles output to
829 RRD-files. Data can be cached to combine multiple updates into one
830 write to increase IO-performance.
831 * network plugin: The new `network' plugin handles IO via the network.
832 It implements a different, much more extensible protocol which can
833 combine many values in one packet, decreasing the number of UDP-
834 packets being sent. It can read from and send to the network and
835 with the appropriate configuration even forward packets to other
837 * unixsock plugin: The new `unixsock' plugin provides an interface to
838 communicate with the daemon while it is running. Right now the
839 commands `GETVAL' and `PUTVAL' are implemented, but more are to
841 * perl plugin: The new `perl' plugin allows you to write extensions
842 for collectd in the scripting-language Perl.
843 * logfile plugin: The new `logfile' plugin writes logmessages to files
845 * syslog plugin: The new `syslog' plugin sends logmessages to the
846 system's syslog daemon.
847 * entropy plugin: The new `entropy' plugin collects the amount of
848 entropy currently being available to the system.
849 * exec plugin: The new `exec' plugin forks child processes and reads
850 back values provided by the forked processes.
851 * iptables plugin: The new `iptables' plugin reads counters from
852 iptables rules. Thanks to Sjoerd van der Berg for contributing this
854 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
855 to Peter Holik for contributing this plugin.
856 * nut plugin: The new `nut' plugin connects the upsd of the `network
857 ups tools' and reads information about the connected UPS.
858 * apache plugin: Support for lighttpd's `BusyServers' (aka.
859 connections) field was added by Florent Monbillard.
860 * collectd-nagios: The new `collectd-nagios' binary queries values
861 from collectd, parses them and exits according to Nagios-standards.
862 * manpages: The manpages have been improved a lot.
864 2007-09-28, Version 3.11.7
865 * wireless plugin: Correct the handling of cards returning signal and

874 * processes plugin: Fix a bug when run under Linux 2.4. All processes
875 were accounted as `zombies'.
877 2007-04-10, Version 3.11.4
878 * dns plugin: Change the order of includes to make the plugin compile
881 2007-03-30, Version 3.11.3
882 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
883 of the unused `COLLECT_KSTAT'.
885 2007-02-11, Version 3.11.2
886 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
887 NULL-pointer may have been passed to `printf' which causes a
888 segfault with some libcs.
890 2007-02-10, Version 3.11.1
891 * df plugin: Some wrong defines have been fixed so the plugin works
893 * dns plugin: The usage of a struct has been fixed to work with
895 * processes plugin: Some missing defines have been added so the plugin
896 compiles cleanly under FreeBSD and presumably other UNIXes.
898 2006-12-22, Version 3.11.0
899 * collectd: The new command line option `-P' makes it easier for
900 distributors to change the location of PID-files.
901 * collectd: The daemon shuts down faster now which makes it easier to
902 write init.d-scripts for it.
903 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
904 caused problems every now and then.
905 * df plugin: New config options allow to ignore certain mountpoints,
906 filesystem types or devices.
907 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
908 and interprets it. It collects traffic as well as qtype, opcode and
910 * email plugin: Sebastian Harl has contributed this plugin which
911 counts received mails in categories (e. g. ham, spam, virus), spam
912 score (as given by SpamAssassin) and check types.
913 * mbmon plugin: Flavio Stanchina has contributed this plugin which
914 uses `mbmon' to gather information from sensors on the motherboard.
915 * processes plugin: Collect detailed statistics for configured
916 processes, that's process and thread count, CPU usage, resident
917 segment size and pagefaults.
918 * multimeter plugin: Peter Holik contributed a new plugin which
920 * sensors plugin: Lubos Stanek has put much effort into improving this
921 plugin, including `extended naming', collection of voltage values
922 and the possibility to ignore certain values.
924 2006-12-21, Version 3.10.4
925 * Max Kellermann has identified a bug in the server routine: When
926 opening a socket fails the daemon will (re)try opening the socket in
927 an endless loop, ultimately leading to a `EMFILE' error.
929 2006-11-04, Version 3.10.3
930 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
931 ntpd's reply was sent in more than one packet, the buffer size was
932 calculated incorrectly, resulting in the reading of uninitialized or
935 2006-11-01, Version 3.10.2
936 * The sample config file has been improved.
937 * Errors in the manpages have been corrected.
938 * The ping-plugin now adds hosts during initialization, not during
939 startup. This speeds up startup when no network connectivity is
940 available. Also, the hosts are being added later when the network is
942 * Improved BSD-support for the df-plugin.
943 * Fixed syntax errors in the swap-plugin for Mac OS X.
944 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
946 * Don't disable the mysql-plugin if connecting to the database fails
947 during initialization. Instead, try again in increasing intervals.
949 2006-07-19, Version 3.10.1
950 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
951 the apcups cannot be reached, unconnected sockets will pile up and
952 eventually lead to `Too many open files' errors.
954 2006-07-09, Version 3.10.0
955 * The `disk' plugin has been ported to Darwin.
956 * The `battery' plugin should work on many Apple computers now.
957 * The `traffic' plugin can now ignore certain interfaces. Also,
958 statistics for sent/received packets and errors have been added.
959 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
960 to Anthony Gialluca for contributing this plugin and providing me
961 with a test environment :)
962 * A plugin for monitoring an NTP instance and the local clock drift
965 2006-06-25, Version 3.9.4
966 * The Solaris code in the `swap' plugin has been changed to reflect
967 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
969 * The debugging system has been fixed to work with the Sun libc.
970 * When built without librrd the variable `operating_mode' could be
971 uninitialized. Thanks to David Elliot for reporting the bug.
973 2006-06-01, Version 3.9.3
974 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
975 operating systems also profit from the changes, but I wasn't able to
977 * Changed the build system to find the netinet-includes under FreeBSD
978 and therefore successfully build the `liboping' library there.
980 2006-05-09, Version 3.9.2
981 * Applied a patch to the `liboping' library. Due to a bug in the
982 sequence checking the `ping' plugin stopped working after
983 approximately 7.6 days.
985 2006-05-09, Version 3.8.5
986 * Applied a patch to the `liboping' library. Due to a bug in the
987 sequence checking the `ping' plugin stopped working after
988 approximately 7.6 days.
990 2006-04-21, Version 3.9.1
991 * Build issues with Solaris and possible other architectures have been
993 * Problems when building the `apache'-plugin without `libcurl' have
995 * A bug in the `ping' plugin has been fixed. Sorry folks.
997 2006-04-02, Version 3.9.0
998 * A plugin to monitor the Apache webserver has been added.
999 <http://httpd.apache.org/>
1000 * A plugin to collect statistics about virtual servers using VServer.
1001 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1003 * A plugin for wireless LAN cards has been added. It monitors signal
1004 strength, link quality and noise ratio..
1005 * A plugin for Apple hardware sensors has been added.
1006 * An option to compile collectd with different `step' and `heartbeat'
1007 settings has been added. The size of RRAs is no longer static but
1008 calculated based on the settings for `step' and `width'.
1009 * The `ping' plugin can now be configured to use a certain TTL.
1010 * A plugin to monitor the hardware sensors of Apple computers has been
1012 * The plugins `cpu', `memory', `processes' and `traffic' have been
1013 ported to Mach/Darwin (Mac OS X).
1014 * The `log mode' has been contributed by Christophe Kalt. It writes
1015 the data into text files rather than RRD files.
1017 2006-04-09, Version 3.8.4
1018 * Applied patch by Vincent Stehlé which improves the disk-name
1019 resolution in the `hddtemp' plugin for Linux systems.
1021 2006-04-02, Version 3.8.3
1022 * Applied a patch by James Byers: The MySQL plugin was not working
1023 with MySQL 5.0.2 or later.
1025 2006-03-14, Version 3.8.2
1026 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1027 the GNU libc, because it points to `/etc/fstab' rather than
1030 2006-03-13, Version 3.8.1
1031 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1032 * Fixes in the debian `postinst' and `init.d' scripts.
1034 2006-03-09, Version 3.8.0
1035 * The `ping' plugin no longer uses `libping' but a self written
1036 library named `liboping'. With this library it's possible to ping
1037 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1039 2006-02-18, Version 3.7.2
1040 * A simple bug in the `battery' plugin has been fixed. It should now
1041 work with ACPI based batteries as well. Thanks to Sebastian for
1043 * Fixing a bug that prevented collectd to be built without librrd.
1044 Thanks to Werner Heuser for reporting it.
1046 2006-02-04, Version 3.7.1
1047 * The new network code has been improved to build with older versions
1049 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1050 to Tommie Gannert for this patch.
1052 2006-01-30, Version 3.7.0
1053 * The `battery' plugin has been added. It collects information about
1055 * The MySQL plugin has been improved: It now writes two more RRD
1056 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1057 * The `cpufreq' plugin now reads another file since the file it did
1058 read so far causes much overhead in the kernel. Also, you need root
1059 to read the old file, but not to read the new one.
1060 * The `hddtemp' plugin can now be configured to connect to another
1061 address and/or port than localhost.
1062 * The `df' plugin now prefers `statvfs' over `statfs'.
1063 * The network code has been rewritten. collectd now supports unicast
1064 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1065 be set in the configfile.
1067 2006-01-24, Version 3.6.2
1068 * Due to a bug in the configfile handling collectd wouldn't start in
1069 client mode. This released fixes this.
1071 2006-01-20, Version 3.6.1
1072 * Due to a bug in `configure.in' all modules and the binary were
1073 linked against `libmysqlclient'. This issue is solved by this
1076 2006-01-17, Version 3.6.0
1077 * A config file has been added. This allows for loading only specific
1079 * A `df' plugin has been added.
1080 * A `mysql' plugin has been added.
1081 * The `ping' plugin doesn't entirely give up hope when a socket error
1082 occurred, but will back of and increase the intervals between tries.
1084 2006-01-21, Version 3.5.2
1085 * Fixed yet another bug in the signal handling.. Stupid typo..
1086 * Improved the ping plugin to not give up on socket errors (backport
1089 2005-12-18, Version 3.5.1
1090 * The PID-file is now deleted correctly when shutting down the daemon.
1091 * SIGINT and SIGTERM are now handled correctly.
1093 2005-12-16, Version 3.5.0 (Revision 326)
1094 * A bug in the `load' module under Solaris has been fixed.
1095 * The `users' module has been contributed by Sebastian Harl. It counts
1096 currently logged in users.
1097 * The CPU module now works under FreeBSD without the use of
1098 `libstatgrab', however SMP support is missing.
1099 * The default directories for the RRD files and the PID file now
1100 depend on the compile time setting of `localstatedir'.
1102 2005-11-15, Version 3.4.0 (Revision 236)
1103 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1104 from gentoo's bugzilla for writing the patch.
1105 * The build dependency for librrd has been removed. Binaries built
1106 without librrd are client-only and will multicast their value as
1107 with the `-c' argument.
1108 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1109 * The newly introduced `-f' switch prevents daemon initialization
1110 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1111 Barcellos for this patch.
1113 2005-11-04, Version 3.3.0 (Revision 216)
1114 * New modules have been added:
1115 - `serial', for monitoring traffic on the serial interfaces
1116 - `nfs', for graphing NFS procedure calls
1117 - `tape', traffic from/to tape devices
1118 * The memory.rrd now accepts more than 4Gig of memory.
1120 2005-10-26, Version 3.2.0 (Revision 200)
1121 * Support for graphing the processes has been added (thanks to Lyonel
1123 * If reading from hddtemp fails collectd will increase the time
1124 between polls up to one day.
1125 * The init.d files have been improved.
1126 * Problems with the spec file have been fixed.
1128 2005-10-16, Version 3.1.0 (Revision 194)
1129 * Added the `setsid' syscall to the startup code.
1130 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1132 2005-09-30, Version 3.0.0 (Revision 184)
1133 * The ability to send/receive data to/from the network (think
1134 multicast) has been added.
1135 * Modules have been split up into shared libraries can be loaded at
1136 runtime. The biggest advantage is that the core program doesn't need
1137 to be linked against an external library.
1138 * A patch by George Kargiotakis has been applied: It fixes the sensors
1139 behaviour then more than one sensor is being queried.
1141 2005-09-16, Version 2.1.0 (Revision 172)
1142 * A module for swap statistics has been added.
1144 2005-09-09, Version 2.0.0 (Revision 135)
1145 * Filenames can no longer be configured at program startup. The only
1146 options as of this version are the directory and ping hosts.
1147 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1148 Soft-IRQ statistics are added to `System'.
1149 * Diskstats now collect read and write bytes, not sectors.
1150 * Ping statistics can now be collected for more than one host. There
1151 is no default any more: If no host is given no host will be pinged.
1152 * A self-written patch for libping has been applied so it builds
1155 2005-09-01, Version 1.8.1 (Revision 123)
1156 * Much improved configure-script: libraries and features may now be
1158 * More detailed warnings/error messages when RRD update fails.
1160 2005-08-29, Version 1.8.0:
1161 * Support for collecting disk statistics under Solaris.
1163 2005-08-25, Version 1.7.0:
1164 * Support for libstatgrab[1] for load, memory usage and network
1165 traffic. CPU- and disk-usage are not (yet) supported, since
1166 libstatgrab returns insufficient information. I will contact the
1168 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1169 aren't necessarily counted linear which is now handled correctly.
1170 [1]: http://www.i-scream.org/libstatgrab/
1172 2005-08-21, Version 1.6.0:
1173 * Basic support for Solaris: System load and cpu-usage can be
1174 collected under Solaris, too. Other stats will follow later.
1175 * Many fixes in the autoconf-script
1176 * Collection/Museum scripts have been added under contrib/museum
1177 * collectd may now be started in unprivileged mode, though ping
1178 statistics will not work.
1180 2005-07-17, Version 1.5.1:
1181 * Diskstats-RRDs now use major/minor for naming. Some systems have
1182 weird strings as disk-names..
1184 2005-07-17, Version 1.5:
1185 * A new module, diskstats, has been added. It collects information
1186 about the disks and partitions.
1188 2005-07-11, Version 1.4.2:
1189 * The meminfo module has been changed to work with more platforms
1190 and/or kernel versions.
1192 2005-07-10, Version 1.4.1: Correct traffic stats
1193 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1194 forgot to correct when I changed that module.
1196 2005-07-09, Version 1.4: More traffic stats
1197 * Traffic is now collected for all interfaces that can be found
1198 * Temperature-statistics are read from lm-sensors if available
1200 2005-07-08, Version 1.3: CPU stats
1201 * Collecting CPU statistics now
1203 2004-07-12, Version 1.2: Using syslog
1204 * collectd is now using the syslog facility to report errors, warnings
1206 * The default directory is now /var/db/collectd
1208 2004-07-10, Version 1.1: Minor changes
1209 * Nothing really useful to say ;)
1211 2004-07-09, Version 1.0: Initial Version
1212 * The following modules are provided:
