114 Bruno Prémont for finding this problem.
115 * bind plugin: Fix collection of the cached RR sets. The number of RR
116 sets currently in the cache was collected as a counter value, which
117 is nonsense. Thanks to Bruno Prémont for implementing this.

167 relational databases and use SQL to gather custom statistics from
168 it. It is similar to the already existing PostgreSQL plugin but uses
169 libdbi to communicate with the database(s).
170 * interface plugin: Use the ignorelist framework when selecting /
171 ignoring interfaces. This allows one to use regular expressions to
172 select interfaces, too.

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

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

271 2008-10-16, Version 4.5.1
272 * build system: Change `--enable-<plugin>' to abort with an error if
273 dependencies are not met. Thanks to Bruno Prémont for the patch.
274 Also, the poisoning of various string functions has been restricted

278 leak in the configuration handling code has been fixed. Thanks to
279 Niraj Tolia for reporting these issues.
280 * collectd: Fix an off-by-one error in the ignorelist functionality.
281 When using regular expressions, the last character would be missing,
282 possibly matching differently from what one would expect.

288 character too long, it was truncated instead of reporting an error.
289 * network plugin: Fix a memory leak in the configuration handling
290 code. Thanks to Niraj Tolia for reporting this issue.
291 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

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

641 of the libsensors library.
643 2007-11-08, Version 4.1.4
644 * Build system: Improve detection of the rrd library, especially if
645 it's in a non-standard location.
646 * Build system: A bug when parsing the argument for
647 `--with-libnetsnmp' has been fixed.
648 * collectd: Implement `strerror_r' if the libc doesn't provide it.
649 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
650 a deadlock or delay when shutting down the daemon.
651 * snmp plugin: Fix a memory leak.
653 2007-10-24, Version 4.1.3
654 * collectd: A build issue under Solaris has been resolved by renaming
656 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
657 be more thread-safe otherwise by locking calls to the library.
659 2007-09-28, Version 4.1.2
660 * apcups plugin: Fix reporting of the `load percent' data.
661 * wireless plugin: Correct the handling of cards returning signal and
662 noise quality as percentage.
663 * perl plugin: Fix a possible buffer overflow in get_module_name().
664 * build system: Further improve the detection of libraries.
665 * netlink plugin: Build issues under some older versions of the Linux
666 includes (i. e. Debian Sarge) have been fixed.
667 * snmp plugin: Fix a potential segfault when a host times out. Add
668 support for the `timeticks' type.
670 2007-09-12, Version 4.1.1
671 * Build system: The detection of `libnetlink' has been improved.
672 * collectd: The documentation has been fixed in numerous places.
673 * exec plugin: Setting the group under which to run a program has been
675 * collectd: The `sstrerror' function was improved to work correctly
676 with the broken GNU version of `strerror_r'.
677 * collectd: Write an error message to STDERR when loading of a plugin
679 * apcups plugin: Fix the `types' used to submit the values: They still
680 has an `apcups_' prefix which doesn't work anymore.
681 * rrdtool plugin: Create new RRD-files with the `begin' time set to
682 whatever the client thinks is `now'..
684 2007-09-01, Version 4.1.0
685 * Build system: The build system has been changed to automatically
686 disable all plugins, which are missing dependencies. The dependency
687 checking has been removed from the plugins themselves to remove
689 * Flexible interval: The interval of collected data is now sent along
690 with the data itself over the network, so that the interval-settings
691 of server and clients no longer needs to match.
692 * netlink plugin: The new `netlink' plugin connects to the Linux
693 kernel using a netlink socket and uses it to query information about
694 interfaces, qdiscs and classes.
695 * rrdtool plugin: The cache is now dumped to disk in an extra thread
696 to not block data collection.
697 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
698 network devices, such as switches, routers, thermometers, rack
699 monitoring servers, etc. The collectd-snmp(5) manpage documents this
701 * unixsock plugin: Added the `LISTVAL' command.
702 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
703 of music played with xmms.
705 2007-09-28, Version 4.0.9
706 * apcups plugin: Fix reporting of the `load percent' data.
707 * wireless plugin: Correct the handling of cards returning signal and
708 noise quality as percentage.
709 * perl plugin: Fix a possible buffer overflow in get_module_name().
711 2007-09-12, Version 4.0.8
712 * collectd: The `sstrerror' function was improved to work correctly
713 with the broken GNU version of `strerror_r'.
714 * collectd: Write an error message to STDERR when loading of a plugin
716 * apcups plugin: Fix the `types' used to submit the values: They still
717 has an `apcups_' prefix which doesn't work anymore.
718 * rrdtool plugin: Create new RRD-files with the `begin' time set to
719 whatever the client thinks is `now'..
721 2007-08-26, Version 4.0.7
722 * documentation: Some typos have been fixed and some information has
724 * build system: Many fixes for detecting libraries in unusual places,
725 such as on RedHat systems. The affected libraries are `libcurl',
726 `libmysql', and `libupsclient'.
727 * network plugin: Allow the `Port' option to be specified as a number
728 (i. e. without quotes).
729 * nut plugin: A fix allows linking the nut plugin against
730 libupsclient, version >= 2.2.0.
731 * processes plugin: Fix a potential segmentation fault.
733 2007-07-30, Version 4.0.6
734 * sensors plugin: Fix the ignorelist functionality: Only the `type
735 instance' was used to match against the list, but the documentation
736 told otherwise. This release fixes the code, so it complies with the
738 * syslog plugin: Call `openlog' right when the plugin is loaded, so
739 configuration messages will end up in the logging facility.
740 * conrtib/fedora: The contributed specfile for Fedora has been
743 2007-07-05, Version 4.0.5
744 * Portability: More fixes for OpenBSD have been included.
746 2007-06-24, Version 4.0.4
747 * cpu plugin: Fixed the Solaris code.
748 * dns plugin: Fixed a build issue for OpenBSD.
749 * interface plugin: Fixed the Solaris code.
750 * load plugin: Fixed the alternative `/proc' Linux code.
751 * memory plugin: Fixed the Solaris code.
752 * oconfig: Don't require `-lfl' anymore.
754 2007-06-19, Version 4.0.3
755 * cpu plugin: Fix the Darwin / Mac OS X code.
756 * ping plugin: Use the return value of `getpid', not its address.
757 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
758 initialized correctly.
759 * configure: Added `--with-nan-emulation' to aid cross compilation.
761 2007-06-12, Version 4.0.2
762 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
763 they're given in numerically form.
765 2007-06-07, Version 4.0.1
766 * iptables plugin: A bug in the configuration routine has been fixed.
767 Setting a comment in the configfile will no longer cause a
770 2007-06-03, Version 4.0.0
771 * collectd: The plugin-infrastructure has been changed to allow for
772 more types of plugins, namely `write' and `log' plugins.
773 * collectd: The read-function has been changed to read many plugins in
774 parallel, using threads. Thus, plugins generally need to use
775 thread-safe functions from now on.
776 * collectd: The '-t' command line options allows to perform syntax tests
777 of the configuration file and exit immediately.
778 * csv plugin: The new `csv' plugin handles output to `comma separated
780 * rrdtool plugin: The new `rrdtool' plugin handles output to
781 RRD-files. Data can be cached to combine multiple updates into one
782 write to increase IO-performance.
783 * network plugin: The new `network' plugin handles IO via the network.
784 It implements a different, much more extensible protocol which can
785 combine many values in one packet, decreasing the number of UDP-
786 packets being sent. It can read from and send to the network and
787 with the appropriate configuration even forward packets to other
789 * unixsock plugin: The new `unixsock' plugin provides an interface to
790 communicate with the daemon while it is running. Right now the
791 commands `GETVAL' and `PUTVAL' are implemented, but more are to
793 * perl plugin: The new `perl' plugin allows you to write extensions
794 for collectd in the scripting-language Perl.
795 * logfile plugin: The new `logfile' plugin writes logmessages to files
797 * syslog plugin: The new `syslog' plugin sends logmessages to the
798 system's syslog daemon.
799 * entropy plugin: The new `entropy' plugin collects the amount of
800 entropy currently being available to the system.
801 * exec plugin: The new `exec' plugin forks child processes and reads
802 back values provided by the forked processes.
803 * iptables plugin: The new `iptables' plugin reads counters from
804 iptables rules. Thanks to Sjoerd van der Berg for contributing this
806 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
807 to Peter Holik for contributing this plugin.
808 * nut plugin: The new `nut' plugin connects the upsd of the `network
809 ups tools' and reads information about the connected UPS.
810 * apache plugin: Support for lighttpd's `BusyServers' (aka.
811 connections) field was added by Florent Monbillard.
812 * collectd-nagios: The new `collectd-nagios' binary queries values
813 from collectd, parses them and exits according to Nagios-standards.
814 * manpages: The manpages have been improved a lot.
816 2007-09-28, Version 3.11.7
817 * wireless plugin: Correct the handling of cards returning signal and
818 noise quality as percentage.
820 2007-08-31, Version 3.11.6
821 * processes plugin: Fix a potential segmentation fault.
823 2007-05-29, Version 3.11.5
824 * configure: Added `AC_SYS_LARGEFILE' for LFS.
825 * ntpd plugin: Fix a potential buffer overflow.
826 * processes plugin: Fix a bug when run under Linux 2.4. All processes
827 were accounted as `zombies'.
829 2007-04-10, Version 3.11.4
830 * dns plugin: Change the order of includes to make the plugin compile
833 2007-03-30, Version 3.11.3
834 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
835 of the unused `COLLECT_KSTAT'.
837 2007-02-11, Version 3.11.2
838 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
839 NULL-pointer may have been passed to `printf' which causes a
840 segfault with some libcs.
842 2007-02-10, Version 3.11.1
843 * df plugin: Some wrong defines have been fixed so the plugin works
845 * dns plugin: The usage of a struct has been fixed to work with
847 * processes plugin: Some missing defines have been added so the plugin
848 compiles cleanly under FreeBSD and presumably other UNIXes.
850 2006-12-22, Version 3.11.0
851 * collectd: The new command line option `-P' makes it easier for
852 distributors to change the location of PID-files.
853 * collectd: The daemon shuts down faster now which makes it easier to
854 write init.d-scripts for it.
855 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
856 caused problems every now and then.
857 * df plugin: New config options allow to ignore certain mountpoints,
858 filesystem types or devices.
859 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
860 and interprets it. It collects traffic as well as qtype, opcode and
862 * email plugin: Sebastian Harl has contributed this plugin which
863 counts received mails in categories (e. g. ham, spam, virus), spam
864 score (as given by SpamAssassin) and check types.
865 * mbmon plugin: Flavio Stanchina has contributed this plugin which
866 uses `mbmon' to gather information from sensors on the motherboard.
867 * processes plugin: Collect detailed statistics for configured
868 processes, that's process and thread count, CPU usage, resident
869 segment size and pagefaults.
870 * multimeter plugin: Peter Holik contributed a new plugin which
872 * sensors plugin: Lubos Stanek has put much effort into improving this
873 plugin, including `extended naming', collection of voltage values
874 and the possibility to ignore certain values.
876 2006-12-21, Version 3.10.4
877 * Max Kellermann has identified a bug in the server routine: When
878 opening a socket fails the daemon will (re)try opening the socket in
879 an endless loop, ultimately leading to a `EMFILE' error.
881 2006-11-04, Version 3.10.3
882 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
883 ntpd's reply was sent in more than one packet, the buffer size was
884 calculated incorrectly, resulting in the reading of uninitialized or
887 2006-11-01, Version 3.10.2
888 * The sample config file has been improved.
889 * Errors in the manpages have been corrected.
890 * The ping-plugin now adds hosts during initialization, not during
891 startup. This speeds up startup when no network connectivity is
892 available. Also, the hosts are being added later when the network is
894 * Improved BSD-support for the df-plugin.
895 * Fixed syntax errors in the swap-plugin for Mac OS X.
896 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
898 * Don't disable the mysql-plugin if connecting to the database fails
899 during initialization. Instead, try again in increasing intervals.
901 2006-07-19, Version 3.10.1
902 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
903 the apcups cannot be reached, unconnected sockets will pile up and
904 eventually lead to `Too many open files' errors.
906 2006-07-09, Version 3.10.0
907 * The `disk' plugin has been ported to Darwin.
908 * The `battery' plugin should work on many Apple computers now.
909 * The `traffic' plugin can now ignore certain interfaces. Also,
910 statistics for sent/received packets and errors have been added.
911 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
912 to Anthony Gialluca for contributing this plugin and providing me
913 with a test environment :)
914 * A plugin for monitoring an NTP instance and the local clock drift
917 2006-06-25, Version 3.9.4
918 * The Solaris code in the `swap' plugin has been changed to reflect
919 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
921 * The debugging system has been fixed to work with the Sun libc.
922 * When built without librrd the variable `operating_mode' could be
923 uninitialized. Thanks to David Elliot for reporting the bug.
925 2006-06-01, Version 3.9.3
926 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
927 operating systems also profit from the changes, but I wasn't able to
929 * Changed the build system to find the netinet-includes under FreeBSD
930 and therefore successfully build the `liboping' library there.
932 2006-05-09, Version 3.9.2
933 * Applied a patch to the `liboping' library. Due to a bug in the
934 sequence checking the `ping' plugin stopped working after
935 approximately 7.6 days.
937 2006-05-09, Version 3.8.5
938 * Applied a patch to the `liboping' library. Due to a bug in the
939 sequence checking the `ping' plugin stopped working after
940 approximately 7.6 days.
942 2006-04-21, Version 3.9.1
943 * Build issues with Solaris and possible other architectures have been
945 * Problems when building the `apache'-plugin without `libcurl' have
947 * A bug in the `ping' plugin has been fixed. Sorry folks.
949 2006-04-02, Version 3.9.0
950 * A plugin to monitor the Apache webserver has been added.
951 <http://httpd.apache.org/>
952 * A plugin to collect statistics about virtual servers using VServer.
953 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
955 * A plugin for wireless LAN cards has been added. It monitors signal
956 strength, link quality and noise ratio..
957 * A plugin for Apple hardware sensors has been added.
958 * An option to compile collectd with different `step' and `heartbeat'
959 settings has been added. The size of RRAs is no longer static but
960 calculated based on the settings for `step' and `width'.
961 * The `ping' plugin can now be configured to use a certain TTL.
962 * A plugin to monitor the hardware sensors of Apple computers has been
964 * The plugins `cpu', `memory', `processes' and `traffic' have been
965 ported to Mach/Darwin (Mac OS X).
966 * The `log mode' has been contributed by Christophe Kalt. It writes
967 the data into text files rather than RRD files.
969 2006-04-09, Version 3.8.4
970 * Applied patch by Vincent Stehlé which improves the disk-name
971 resolution in the `hddtemp' plugin for Linux systems.
973 2006-04-02, Version 3.8.3
974 * Applied a patch by James Byers: The MySQL plugin was not working
975 with MySQL 5.0.2 or later.
977 2006-03-14, Version 3.8.2
978 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
979 the GNU libc, because it points to `/etc/fstab' rather than
982 2006-03-13, Version 3.8.1
983 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
984 * Fixes in the debian `postinst' and `init.d' scripts.
986 2006-03-09, Version 3.8.0
987 * The `ping' plugin no longer uses `libping' but a self written
988 library named `liboping'. With this library it's possible to ping
989 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
991 2006-02-18, Version 3.7.2
992 * A simple bug in the `battery' plugin has been fixed. It should now
993 work with ACPI based batteries as well. Thanks to Sebastian for
995 * Fixing a bug that prevented collectd to be built without librrd.
996 Thanks to Werner Heuser for reporting it.
998 2006-02-04, Version 3.7.1
999 * The new network code has been improved to build with older versions
1001 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1002 to Tommie Gannert for this patch.
1004 2006-01-30, Version 3.7.0
1005 * The `battery' plugin has been added. It collects information about
1007 * The MySQL plugin has been improved: It now writes two more RRD
1008 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1009 * The `cpufreq' plugin now reads another file since the file it did
1010 read so far causes much overhead in the kernel. Also, you need root
1011 to read the old file, but not to read the new one.
1012 * The `hddtemp' plugin can now be configured to connect to another
1013 address and/or port than localhost.
1014 * The `df' plugin now prefers `statvfs' over `statfs'.
1015 * The network code has been rewritten. collectd now supports unicast
1016 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1017 be set in the configfile.
1019 2006-01-24, Version 3.6.2
1020 * Due to a bug in the configfile handling collectd wouldn't start in
1021 client mode. This released fixes this.
1023 2006-01-20, Version 3.6.1
1024 * Due to a bug in `configure.in' all modules and the binary were
1025 linked against `libmysqlclient'. This issue is solved by this
1028 2006-01-17, Version 3.6.0
1029 * A config file has been added. This allows for loading only specific
1031 * A `df' plugin has been added.
1032 * A `mysql' plugin has been added.
1033 * The `ping' plugin doesn't entirely give up hope when a socket error
1034 occurred, but will back of and increase the intervals between tries.
1036 2006-01-21, Version 3.5.2
1037 * Fixed yet another bug in the signal handling.. Stupid typo..
1038 * Improved the ping plugin to not give up on socket errors (backport
1041 2005-12-18, Version 3.5.1
1042 * The PID-file is now deleted correctly when shutting down the daemon.
1043 * SIGINT and SIGTERM are now handled correctly.
1045 2005-12-16, Version 3.5.0 (Revision 326)
1046 * A bug in the `load' module under Solaris has been fixed.
1047 * The `users' module has been contributed by Sebastian Harl. It counts
1048 currently logged in users.
1049 * The CPU module now works under FreeBSD without the use of
1050 `libstatgrab', however SMP support is missing.
1051 * The default directories for the RRD files and the PID file now
1052 depend on the compile time setting of `localstatedir'.
1054 2005-11-15, Version 3.4.0 (Revision 236)
1055 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1056 from gentoo's bugzilla for writing the patch.
1057 * The build dependency for librrd has been removed. Binaries built
1058 without librrd are client-only and will multicast their value as
1059 with the `-c' argument.
1060 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1061 * The newly introduced `-f' switch prevents daemon initialization
1062 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1063 Barcellos for this patch.
1065 2005-11-04, Version 3.3.0 (Revision 216)
1066 * New modules have been added:
1067 - `serial', for monitoring traffic on the serial interfaces
1068 - `nfs', for graphing NFS procedure calls
1069 - `tape', traffic from/to tape devices
1070 * The memory.rrd now accepts more than 4Gig of memory.
1072 2005-10-26, Version 3.2.0 (Revision 200)
1073 * Support for graphing the processes has been added (thanks to Lyonel
1075 * If reading from hddtemp fails collectd will increase the time
1076 between polls up to one day.
1077 * The init.d files have been improved.
1078 * Problems with the spec file have been fixed.
1080 2005-10-16, Version 3.1.0 (Revision 194)
1081 * Added the `setsid' syscall to the startup code.
1082 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1084 2005-09-30, Version 3.0.0 (Revision 184)
1085 * The ability to send/receive data to/from the network (think
1086 multicast) has been added.
1087 * Modules have been split up into shared libraries can be loaded at
1088 runtime. The biggest advantage is that the core program doesn't need
1089 to be linked against an external library.
1090 * A patch by George Kargiotakis has been applied: It fixes the sensors
1091 behaviour then more than one sensor is being queried.
1093 2005-09-16, Version 2.1.0 (Revision 172)
1094 * A module for swap statistics has been added.
1096 2005-09-09, Version 2.0.0 (Revision 135)
1097 * Filenames can no longer be configured at program startup. The only
1098 options as of this version are the directory and ping hosts.
1099 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1100 Soft-IRQ statistics are added to `System'.
1101 * Diskstats now collect read and write bytes, not sectors.
1102 * Ping statistics can now be collected for more than one host. There
1103 is no default any more: If no host is given no host will be pinged.
1104 * A self-written patch for libping has been applied so it builds
1107 2005-09-01, Version 1.8.1 (Revision 123)
1108 * Much improved configure-script: libraries and features may now be
1110 * More detailed warnings/error messages when RRD update fails.
1112 2005-08-29, Version 1.8.0:
1113 * Support for collecting disk statistics under Solaris.
1115 2005-08-25, Version 1.7.0:
1116 * Support for libstatgrab[1] for load, memory usage and network
1117 traffic. CPU- and disk-usage are not (yet) supported, since
1118 libstatgrab returns insufficient information. I will contact the
1120 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1121 aren't necessarily counted linear which is now handled correctly.
1122 [1]: http://www.i-scream.org/libstatgrab/
1124 2005-08-21, Version 1.6.0:
1125 * Basic support for Solaris: System load and cpu-usage can be
1126 collected under Solaris, too. Other stats will follow later.
1127 * Many fixes in the autoconf-script
1128 * Collection/Museum scripts have been added under contrib/museum
1129 * collectd may now be started in unprivileged mode, though ping
1130 statistics will not work.
1132 2005-07-17, Version 1.5.1:
1133 * Diskstats-RRDs now use major/minor for naming. Some systems have
1134 weird strings as disk-names..
1136 2005-07-17, Version 1.5:
1137 * A new module, diskstats, has been added. It collects information
1138 about the disks and partitions.
1140 2005-07-11, Version 1.4.2:
1141 * The meminfo module has been changed to work with more platforms
1142 and/or kernel versions.
1144 2005-07-10, Version 1.4.1: Correct traffic stats
1145 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1146 forgot to correct when I changed that module.
1148 2005-07-09, Version 1.4: More traffic stats
1149 * Traffic is now collected for all interfaces that can be found
1150 * Temperature-statistics are read from lm-sensors if available
1152 2005-07-08, Version 1.3: CPU stats
1153 * Collecting CPU statistics now
1155 2004-07-12, Version 1.2: Using syslog
1156 * collectd is now using the syslog facility to report errors, warnings
1158 * The default directory is now /var/db/collectd
1160 2004-07-10, Version 1.1: Minor changes
1161 * Nothing really useful to say ;)
1163 2004-07-09, Version 1.0: Initial Version
1164 * The following modules are provided:
