102 name which prevented this match to be used as documented. Thanks to
103 Bruno Prémont for finding this problem.
104 * bind plugin: Fix collection of the cached RR sets. The number of RR
105 sets currently in the cache was collected as a counter value, which
106 is nonsense. Thanks to Bruno Prémont for implementing this.

154 them using the same mechanism that's used in the tail plugin.
155 * dbi plugin: This new plugin allows you to connect to a variety of
156 relational databases and use SQL to gather custom statistics from
157 it. It is similar to the already existing PostgreSQL plugin but uses
158 libdbi to communicate with the database(s).
159 * interface plugin: Use the ignorelist framework when selecting /
160 ignoring interfaces. This allows one to use regular expressions to
161 select interfaces, too.

234 Solaris, in the configure script automatically.
235 * build system, tcpconns plugin: Check for `kvm_nlist' and
236 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

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

260 2008-10-16, Version 4.5.1
261 * build system: Change `--enable-<plugin>' to abort with an error if
262 dependencies are not met. Thanks to Bruno Prémont for the patch.
263 Also, the poisoning of various string functions has been restricted

267 leak in the configuration handling code has been fixed. Thanks to
268 Niraj Tolia for reporting these issues.
269 * collectd: Fix an off-by-one error in the ignorelist functionality.
270 When using regular expressions, the last character would be missing,
271 possibly matching differently from what one would expect.
272 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
274 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
275 Linzberger for reporting the bug.
276 * iptables plugin: Fix an off-by-one error. If a string was just one
277 character too long, it was truncated instead of reporting an error.
278 * network plugin: Fix a memory leak in the configuration handling
279 code. Thanks to Niraj Tolia for reporting this issue.
280 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

508 * csv plugin: The CSV plugin is now able to store counter values as a
509 rate, using the `StoreRates' configuration option.
510 * exec plugin: Handling of notifications has been added and the
511 ability to pass arguments to the executed programs has been added.
512 * hddtemp plugin: The new `TranslateDevicename' option lets you
513 disable the translation from device names to major-minor-numbers.
514 * logfile plugin: Handling of notifications has been added.
515 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
516 domain name lookups in this plugin.
517 * perl plugin: Many internal changes added support for handling multiple
518 threads making the plugin reasonably usable inside collectd. The API has
519 been extended to support notifications and export global variables to
520 Perl plugins; callbacks now have to be identified by name rather than a
521 pointer to a subroutine. The plugin is no longer experimental.
522 * uuid plugin: The new UUID plugin sets the hostname to an unique
523 identifier for this host. This is meant for setups where each client
524 may migrate to another physical host, possibly going through one or
525 more name changes in the process. Thanks to Richard Jones from
526 Red Hat's Emerging Technology group for this plugin.
527 * libvirt: The new libvirt plugin uses the `libvirt' library to query
528 CPU, disk and network statistics about guest systems on the same
529 physical server. Thanks to Richard Jones from Red Hat's Emerging
530 Technology group for this plugin.
532 2008-04-22, Version 4.2.7
533 * build system: Improved detection of several libraries, especially if
534 they are in non-standard paths.
535 * build system: Portability fixes: Automatically define "_REENTRANT"
536 if the libc expects it.
537 * collectd: Error and warning messages have been improved.
538 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
540 * apache plugin: Allocate new memory when reading a webpage instead of
541 using a buffer of static size.
542 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
544 * hddtemp plugin: Error and warning messages have been improved.
545 * sensors plugin: Fix sensor collection for some chip types.
547 2008-03-29, Version 4.2.6
548 * collectd: Improved error messages when parsing the configuration.
549 * sensors plugin: Fix temperature collection with libsensors4.

551 * wireless plugin: Fix reading noise value.
553 2008-03-04, Version 4.2.5
554 * apache plugin: Improved initialization and error messages.
555 * exec plugin: Set supplementary group IDs.
557 + Create separate threads for reading from the socket and parsing
558 and dispatching incoming packets. Versions prior to this may have
559 problems in high-load situations, where the socket receive buffers
560 overflows, resulting in gaps in the data.
561 + Use `memcpy' when constructing/parsing a package to avoid
562 alignment problems on weird architectures, such as Sparc.
563 + Translate doubles to/from the x86 byte representation to ensure
564 cross-platform compatibility.
565 * ping plugin: Correct the handling of the `TTL' setting.
566 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
567 * swap plugin: Reapply a patch for Solaris.
568 * tcpconns plugin: Portability improvements.
570 2008-01-21, Version 4.2.4
571 * unixsock plugin: A bug in the unixsock plugin caused it not to set
572 the permission on the socket as documented in the manpage. Thanks to
573 Evgeny Chukreev for fixing this issue.
574 * collectd: The documentation has been improved.
576 2007-12-28, Version 4.2.3
577 * sensors plugin: Updated the plugin to build and work with version 3
578 of the libsensors library.
580 2007-12-15, Version 4.2.2
581 * nginx plugin: Incorrect comparison of strings lead to a segfault
582 when using the plugin. Thanks to Saulius Grigaliunas for fixing
584 * logfile plugin: The config option `Timestamp' was handled
585 incorrectly and basically always active. Thanks to Luke Heberling
588 2007-11-08, Version 4.2.1
589 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
591 * snmp plugin: Fix a memory leak.
593 2007-10-27, Version 4.2.0
594 * collectd: The new config option `Include' lets you include other
595 configfiles and thus split up your config into smaller parts. This
596 may be especially interesting for the snmp plugin to keep the data
597 definitions separate from the host definitions.
598 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
599 (number of connections, octets and packets for each service and
600 destination). Thanks to Sebastian Harl for this plugin.
601 * memcached plugin: The new `memcached' plugin connects to a memcached
602 daemon process and collects statistics of this distributed caching
603 system. Thanks to Antony Dovgal for contributing this plugin.
604 * nginx plugin: The new `nginx' plugin reads the status page of an
605 nginx daemon and saves the handled connections and requests.
606 * perl plugin: Many changes, including the added `EnableDebugger'
607 config option which lets you debug your Perl plugins more easily.
608 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
609 be more thread-safe otherwise by locking calls to the library.
610 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
611 correct the values returned by SNMP-agents. If a <data> block is
612 defined as `table' the instance is now optional. The sequence number
613 is used as the type-instance in this case. The new `InstancePrefix'
614 option allows to add arbitrary prefixes to the type-instance.
615 * tcpconns plugin: The new `tcpconns' plugin collects the number of
616 certain TCP connections and what state they're in. This can be used
617 to see how many connections your FTP server has to handle or how
618 many outgoing connections your mailserver has open.
620 2008-01-11, Version 4.1.6
621 * unixsock plugin: A bug in the unixsock plugin caused it not to set
622 the permission on the socket as documented in the manpage. Thanks to
623 Evgeny Chukreev for fixing this issue.
624 * collectd: The documentation has been improved.
626 2007-12-27, Version 4.1.5

630 of the libsensors library.
632 2007-11-08, Version 4.1.4
633 * Build system: Improve detection of the rrd library, especially if
634 it's in a non-standard location.
635 * Build system: A bug when parsing the argument for
636 `--with-libnetsnmp' has been fixed.
637 * collectd: Implement `strerror_r' if the libc doesn't provide it.
638 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
639 a deadlock or delay when shutting down the daemon.
640 * snmp plugin: Fix a memory leak.
642 2007-10-24, Version 4.1.3
643 * collectd: A build issue under Solaris has been resolved by renaming
645 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
646 be more thread-safe otherwise by locking calls to the library.
648 2007-09-28, Version 4.1.2
649 * apcups plugin: Fix reporting of the `load percent' data.
650 * wireless plugin: Correct the handling of cards returning signal and
651 noise quality as percentage.
652 * perl plugin: Fix a possible buffer overflow in get_module_name().
653 * build system: Further improve the detection of libraries.
654 * netlink plugin: Build issues under some older versions of the Linux
655 includes (i. e. Debian Sarge) have been fixed.

660 * Build system: The detection of `libnetlink' has been improved.
661 * collectd: The documentation has been fixed in numerous places.
662 * exec plugin: Setting the group under which to run a program has been
664 * collectd: The `sstrerror' function was improved to work correctly
665 with the broken GNU version of `strerror_r'.
666 * collectd: Write an error message to STDERR when loading of a plugin
668 * apcups plugin: Fix the `types' used to submit the values: They still
669 has an `apcups_' prefix which doesn't work anymore.
670 * rrdtool plugin: Create new RRD-files with the `begin' time set to
671 whatever the client thinks is `now'..
673 2007-09-01, Version 4.1.0
674 * Build system: The build system has been changed to automatically
675 disable all plugins, which are missing dependencies. The dependency
676 checking has been removed from the plugins themselves to remove
678 * Flexible interval: The interval of collected data is now sent along
679 with the data itself over the network, so that the interval-settings
680 of server and clients no longer needs to match.
681 * netlink plugin: The new `netlink' plugin connects to the Linux
682 kernel using a netlink socket and uses it to query information about
683 interfaces, qdiscs and classes.
684 * rrdtool plugin: The cache is now dumped to disk in an extra thread
685 to not block data collection.
686 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
687 network devices, such as switches, routers, thermometers, rack
688 monitoring servers, etc. The collectd-snmp(5) manpage documents this
690 * unixsock plugin: Added the `LISTVAL' command.
691 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
692 of music played with xmms.
694 2007-09-28, Version 4.0.9
695 * apcups plugin: Fix reporting of the `load percent' data.
696 * wireless plugin: Correct the handling of cards returning signal and
697 noise quality as percentage.
698 * perl plugin: Fix a possible buffer overflow in get_module_name().
700 2007-09-12, Version 4.0.8
701 * collectd: The `sstrerror' function was improved to work correctly
702 with the broken GNU version of `strerror_r'.
703 * collectd: Write an error message to STDERR when loading of a plugin
705 * apcups plugin: Fix the `types' used to submit the values: They still
706 has an `apcups_' prefix which doesn't work anymore.
707 * rrdtool plugin: Create new RRD-files with the `begin' time set to
708 whatever the client thinks is `now'..
710 2007-08-26, Version 4.0.7
711 * documentation: Some typos have been fixed and some information has
713 * build system: Many fixes for detecting libraries in unusual places,
714 such as on RedHat systems. The affected libraries are `libcurl',
715 `libmysql', and `libupsclient'.
716 * network plugin: Allow the `Port' option to be specified as a number
717 (i. e. without quotes).
718 * nut plugin: A fix allows linking the nut plugin against
719 libupsclient, version >= 2.2.0.
720 * processes plugin: Fix a potential segmentation fault.
722 2007-07-30, Version 4.0.6
723 * sensors plugin: Fix the ignorelist functionality: Only the `type
724 instance' was used to match against the list, but the documentation
725 told otherwise. This release fixes the code, so it complies with the
727 * syslog plugin: Call `openlog' right when the plugin is loaded, so
728 configuration messages will end up in the logging facility.
729 * conrtib/fedora: The contributed specfile for Fedora has been
732 2007-07-05, Version 4.0.5
733 * Portability: More fixes for OpenBSD have been included.
735 2007-06-24, Version 4.0.4
736 * cpu plugin: Fixed the Solaris code.
737 * dns plugin: Fixed a build issue for OpenBSD.
738 * interface plugin: Fixed the Solaris code.
739 * load plugin: Fixed the alternative `/proc' Linux code.
740 * memory plugin: Fixed the Solaris code.
741 * oconfig: Don't require `-lfl' anymore.
743 2007-06-19, Version 4.0.3
744 * cpu plugin: Fix the Darwin / Mac OS X code.
745 * ping plugin: Use the return value of `getpid', not its address.
746 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
747 initialized correctly.
748 * configure: Added `--with-nan-emulation' to aid cross compilation.
750 2007-06-12, Version 4.0.2

752 they're given in numerically form.
754 2007-06-07, Version 4.0.1
755 * iptables plugin: A bug in the configuration routine has been fixed.
756 Setting a comment in the configfile will no longer cause a
759 2007-06-03, Version 4.0.0
760 * collectd: The plugin-infrastructure has been changed to allow for
761 more types of plugins, namely `write' and `log' plugins.
762 * collectd: The read-function has been changed to read many plugins in
763 parallel, using threads. Thus, plugins generally need to use
764 thread-safe functions from now on.
765 * collectd: The '-t' command line options allows to perform syntax tests
766 of the configuration file and exit immediately.
767 * csv plugin: The new `csv' plugin handles output to `comma separated
769 * rrdtool plugin: The new `rrdtool' plugin handles output to
770 RRD-files. Data can be cached to combine multiple updates into one
771 write to increase IO-performance.
772 * network plugin: The new `network' plugin handles IO via the network.
773 It implements a different, much more extensible protocol which can
774 combine many values in one packet, decreasing the number of UDP-
775 packets being sent. It can read from and send to the network and
776 with the appropriate configuration even forward packets to other
778 * unixsock plugin: The new `unixsock' plugin provides an interface to
779 communicate with the daemon while it is running. Right now the
780 commands `GETVAL' and `PUTVAL' are implemented, but more are to
782 * perl plugin: The new `perl' plugin allows you to write extensions
783 for collectd in the scripting-language Perl.
784 * logfile plugin: The new `logfile' plugin writes logmessages to files
786 * syslog plugin: The new `syslog' plugin sends logmessages to the
787 system's syslog daemon.
788 * entropy plugin: The new `entropy' plugin collects the amount of
789 entropy currently being available to the system.
790 * exec plugin: The new `exec' plugin forks child processes and reads
791 back values provided by the forked processes.
792 * iptables plugin: The new `iptables' plugin reads counters from
793 iptables rules. Thanks to Sjoerd van der Berg for contributing this
795 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
796 to Peter Holik for contributing this plugin.
797 * nut plugin: The new `nut' plugin connects the upsd of the `network
798 ups tools' and reads information about the connected UPS.
799 * apache plugin: Support for lighttpd's `BusyServers' (aka.
800 connections) field was added by Florent Monbillard.
801 * collectd-nagios: The new `collectd-nagios' binary queries values
802 from collectd, parses them and exits according to Nagios-standards.
803 * manpages: The manpages have been improved a lot.
805 2007-09-28, Version 3.11.7
806 * wireless plugin: Correct the handling of cards returning signal and
807 noise quality as percentage.
809 2007-08-31, Version 3.11.6

813 * configure: Added `AC_SYS_LARGEFILE' for LFS.
814 * ntpd plugin: Fix a potential buffer overflow.
815 * processes plugin: Fix a bug when run under Linux 2.4. All processes
816 were accounted as `zombies'.
818 2007-04-10, Version 3.11.4
819 * dns plugin: Change the order of includes to make the plugin compile
822 2007-03-30, Version 3.11.3
823 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
824 of the unused `COLLECT_KSTAT'.
826 2007-02-11, Version 3.11.2
827 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
828 NULL-pointer may have been passed to `printf' which causes a
829 segfault with some libcs.
831 2007-02-10, Version 3.11.1
832 * df plugin: Some wrong defines have been fixed so the plugin works
834 * dns plugin: The usage of a struct has been fixed to work with
836 * processes plugin: Some missing defines have been added so the plugin
837 compiles cleanly under FreeBSD and presumably other UNIXes.
839 2006-12-22, Version 3.11.0
840 * collectd: The new command line option `-P' makes it easier for
841 distributors to change the location of PID-files.
842 * collectd: The daemon shuts down faster now which makes it easier to
843 write init.d-scripts for it.
844 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
845 caused problems every now and then.
846 * df plugin: New config options allow to ignore certain mountpoints,
847 filesystem types or devices.
848 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
849 and interprets it. It collects traffic as well as qtype, opcode and
851 * email plugin: Sebastian Harl has contributed this plugin which
852 counts received mails in categories (e. g. ham, spam, virus), spam
853 score (as given by SpamAssassin) and check types.
854 * mbmon plugin: Flavio Stanchina has contributed this plugin which
855 uses `mbmon' to gather information from sensors on the motherboard.
856 * processes plugin: Collect detailed statistics for configured
857 processes, that's process and thread count, CPU usage, resident
858 segment size and pagefaults.
859 * multimeter plugin: Peter Holik contributed a new plugin which
861 * sensors plugin: Lubos Stanek has put much effort into improving this
862 plugin, including `extended naming', collection of voltage values
863 and the possibility to ignore certain values.
865 2006-12-21, Version 3.10.4
866 * Max Kellermann has identified a bug in the server routine: When
867 opening a socket fails the daemon will (re)try opening the socket in
868 an endless loop, ultimately leading to a `EMFILE' error.
870 2006-11-04, Version 3.10.3
871 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
872 ntpd's reply was sent in more than one packet, the buffer size was
873 calculated incorrectly, resulting in the reading of uninitialized or
876 2006-11-01, Version 3.10.2
877 * The sample config file has been improved.
878 * Errors in the manpages have been corrected.
879 * The ping-plugin now adds hosts during initialization, not during
880 startup. This speeds up startup when no network connectivity is
881 available. Also, the hosts are being added later when the network is
883 * Improved BSD-support for the df-plugin.
884 * Fixed syntax errors in the swap-plugin for Mac OS X.
885 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
887 * Don't disable the mysql-plugin if connecting to the database fails
888 during initialization. Instead, try again in increasing intervals.
890 2006-07-19, Version 3.10.1
891 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
892 the apcups cannot be reached, unconnected sockets will pile up and
893 eventually lead to `Too many open files' errors.
895 2006-07-09, Version 3.10.0
896 * The `disk' plugin has been ported to Darwin.
897 * The `battery' plugin should work on many Apple computers now.
898 * The `traffic' plugin can now ignore certain interfaces. Also,
899 statistics for sent/received packets and errors have been added.
900 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
901 to Anthony Gialluca for contributing this plugin and providing me
902 with a test environment :)
903 * A plugin for monitoring an NTP instance and the local clock drift
906 2006-06-25, Version 3.9.4
907 * The Solaris code in the `swap' plugin has been changed to reflect
908 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
910 * The debugging system has been fixed to work with the Sun libc.
911 * When built without librrd the variable `operating_mode' could be
912 uninitialized. Thanks to David Elliot for reporting the bug.
914 2006-06-01, Version 3.9.3
915 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
916 operating systems also profit from the changes, but I wasn't able to
918 * Changed the build system to find the netinet-includes under FreeBSD
919 and therefore successfully build the `liboping' library there.
921 2006-05-09, Version 3.9.2
922 * Applied a patch to the `liboping' library. Due to a bug in the
923 sequence checking the `ping' plugin stopped working after
924 approximately 7.6 days.
926 2006-05-09, Version 3.8.5
927 * Applied a patch to the `liboping' library. Due to a bug in the
928 sequence checking the `ping' plugin stopped working after
929 approximately 7.6 days.
931 2006-04-21, Version 3.9.1
932 * Build issues with Solaris and possible other architectures have been
934 * Problems when building the `apache'-plugin without `libcurl' have
936 * A bug in the `ping' plugin has been fixed. Sorry folks.
938 2006-04-02, Version 3.9.0
939 * A plugin to monitor the Apache webserver has been added.
940 <http://httpd.apache.org/>
941 * A plugin to collect statistics about virtual servers using VServer.
942 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
944 * A plugin for wireless LAN cards has been added. It monitors signal
945 strength, link quality and noise ratio..
946 * A plugin for Apple hardware sensors has been added.
947 * An option to compile collectd with different `step' and `heartbeat'
948 settings has been added. The size of RRAs is no longer static but
949 calculated based on the settings for `step' and `width'.
950 * The `ping' plugin can now be configured to use a certain TTL.
951 * A plugin to monitor the hardware sensors of Apple computers has been
953 * The plugins `cpu', `memory', `processes' and `traffic' have been
954 ported to Mach/Darwin (Mac OS X).
955 * The `log mode' has been contributed by Christophe Kalt. It writes
956 the data into text files rather than RRD files.
958 2006-04-09, Version 3.8.4
959 * Applied patch by Vincent Stehlé which improves the disk-name
960 resolution in the `hddtemp' plugin for Linux systems.
962 2006-04-02, Version 3.8.3
963 * Applied a patch by James Byers: The MySQL plugin was not working
964 with MySQL 5.0.2 or later.
966 2006-03-14, Version 3.8.2
967 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
968 the GNU libc, because it points to `/etc/fstab' rather than
971 2006-03-13, Version 3.8.1
972 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
973 * Fixes in the debian `postinst' and `init.d' scripts.
975 2006-03-09, Version 3.8.0
976 * The `ping' plugin no longer uses `libping' but a self written
977 library named `liboping'. With this library it's possible to ping
978 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
980 2006-02-18, Version 3.7.2
981 * A simple bug in the `battery' plugin has been fixed. It should now
982 work with ACPI based batteries as well. Thanks to Sebastian for
984 * Fixing a bug that prevented collectd to be built without librrd.
985 Thanks to Werner Heuser for reporting it.
987 2006-02-04, Version 3.7.1
988 * The new network code has been improved to build with older versions
990 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
991 to Tommie Gannert for this patch.
993 2006-01-30, Version 3.7.0
994 * The `battery' plugin has been added. It collects information about
996 * The MySQL plugin has been improved: It now writes two more RRD
997 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
998 * The `cpufreq' plugin now reads another file since the file it did
999 read so far causes much overhead in the kernel. Also, you need root
1000 to read the old file, but not to read the new one.
1001 * The `hddtemp' plugin can now be configured to connect to another
1002 address and/or port than localhost.
1003 * The `df' plugin now prefers `statvfs' over `statfs'.
1004 * The network code has been rewritten. collectd now supports unicast
1005 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1006 be set in the configfile.
1008 2006-01-24, Version 3.6.2
1009 * Due to a bug in the configfile handling collectd wouldn't start in
1010 client mode. This released fixes this.
1012 2006-01-20, Version 3.6.1
1013 * Due to a bug in `configure.in' all modules and the binary were
1014 linked against `libmysqlclient'. This issue is solved by this
1017 2006-01-17, Version 3.6.0
1018 * A config file has been added. This allows for loading only specific
1020 * A `df' plugin has been added.
1021 * A `mysql' plugin has been added.
1022 * The `ping' plugin doesn't entirely give up hope when a socket error
1023 occurred, but will back of and increase the intervals between tries.
1025 2006-01-21, Version 3.5.2
1026 * Fixed yet another bug in the signal handling.. Stupid typo..
1027 * Improved the ping plugin to not give up on socket errors (backport
1030 2005-12-18, Version 3.5.1
1031 * The PID-file is now deleted correctly when shutting down the daemon.
1032 * SIGINT and SIGTERM are now handled correctly.
1034 2005-12-16, Version 3.5.0 (Revision 326)
1035 * A bug in the `load' module under Solaris has been fixed.
1036 * The `users' module has been contributed by Sebastian Harl. It counts
1037 currently logged in users.
1038 * The CPU module now works under FreeBSD without the use of
1039 `libstatgrab', however SMP support is missing.
1040 * The default directories for the RRD files and the PID file now
1041 depend on the compile time setting of `localstatedir'.
1043 2005-11-15, Version 3.4.0 (Revision 236)
1044 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1045 from gentoo's bugzilla for writing the patch.
1046 * The build dependency for librrd has been removed. Binaries built
1047 without librrd are client-only and will multicast their value as
1048 with the `-c' argument.
1049 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1050 * The newly introduced `-f' switch prevents daemon initialization
1051 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1052 Barcellos for this patch.
1054 2005-11-04, Version 3.3.0 (Revision 216)
1055 * New modules have been added:
1056 - `serial', for monitoring traffic on the serial interfaces
1057 - `nfs', for graphing NFS procedure calls
1058 - `tape', traffic from/to tape devices
1059 * The memory.rrd now accepts more than 4Gig of memory.
1061 2005-10-26, Version 3.2.0 (Revision 200)
1062 * Support for graphing the processes has been added (thanks to Lyonel
1064 * If reading from hddtemp fails collectd will increase the time
1065 between polls up to one day.
1066 * The init.d files have been improved.
1067 * Problems with the spec file have been fixed.
1069 2005-10-16, Version 3.1.0 (Revision 194)
1070 * Added the `setsid' syscall to the startup code.
1071 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1073 2005-09-30, Version 3.0.0 (Revision 184)
1074 * The ability to send/receive data to/from the network (think
1075 multicast) has been added.
1076 * Modules have been split up into shared libraries can be loaded at
1077 runtime. The biggest advantage is that the core program doesn't need
1078 to be linked against an external library.
1079 * A patch by George Kargiotakis has been applied: It fixes the sensors
1080 behaviour then more than one sensor is being queried.
1082 2005-09-16, Version 2.1.0 (Revision 172)
1083 * A module for swap statistics has been added.
1085 2005-09-09, Version 2.0.0 (Revision 135)
1086 * Filenames can no longer be configured at program startup. The only
1087 options as of this version are the directory and ping hosts.
1088 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1089 Soft-IRQ statistics are added to `System'.
1090 * Diskstats now collect read and write bytes, not sectors.
1091 * Ping statistics can now be collected for more than one host. There
1092 is no default any more: If no host is given no host will be pinged.
1093 * A self-written patch for libping has been applied so it builds
1096 2005-09-01, Version 1.8.1 (Revision 123)
1097 * Much improved configure-script: libraries and features may now be
1099 * More detailed warnings/error messages when RRD update fails.
1101 2005-08-29, Version 1.8.0:
1102 * Support for collecting disk statistics under Solaris.
1104 2005-08-25, Version 1.7.0:
1105 * Support for libstatgrab[1] for load, memory usage and network
1106 traffic. CPU- and disk-usage are not (yet) supported, since
1107 libstatgrab returns insufficient information. I will contact the
1109 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1110 aren't necessarily counted linear which is now handled correctly.
1111 [1]: http://www.i-scream.org/libstatgrab/
1113 2005-08-21, Version 1.6.0:
1114 * Basic support for Solaris: System load and cpu-usage can be
1115 collected under Solaris, too. Other stats will follow later.
1116 * Many fixes in the autoconf-script
1117 * Collection/Museum scripts have been added under contrib/museum
1118 * collectd may now be started in unprivileged mode, though ping
1119 statistics will not work.
1121 2005-07-17, Version 1.5.1:
1122 * Diskstats-RRDs now use major/minor for naming. Some systems have
1123 weird strings as disk-names..
1125 2005-07-17, Version 1.5:
1126 * A new module, diskstats, has been added. It collects information
1127 about the disks and partitions.
1129 2005-07-11, Version 1.4.2:
1130 * The meminfo module has been changed to work with more platforms
1131 and/or kernel versions.
1133 2005-07-10, Version 1.4.1: Correct traffic stats
1134 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1135 forgot to correct when I changed that module.
1137 2005-07-09, Version 1.4: More traffic stats
1138 * Traffic is now collected for all interfaces that can be found
1139 * Temperature-statistics are read from lm-sensors if available
1141 2005-07-08, Version 1.3: CPU stats
1142 * Collecting CPU statistics now
1144 2004-07-12, Version 1.2: Using syslog
1145 * collectd is now using the syslog facility to report errors, warnings
1147 * The default directory is now /var/db/collectd
1149 2004-07-10, Version 1.1: Minor changes
1150 * Nothing really useful to say ;)
1152 2004-07-09, Version 1.0: Initial Version
1153 * The following modules are provided:
