134 name which prevented this match to be used as documented. Thanks to
135 Bruno Prémont for finding this problem.
136 * bind plugin: Fix collection of the cached RR sets. The number of RR
137 sets currently in the cache was collected as a counter value, which
138 is nonsense. Thanks to Bruno Prémont for implementing this.
139 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
140 primarily BSDs, don't take it well and crash.
141 * oracle plugin: Portability to 64 bit systems has been improved.
142 * postgresql plugin: The default configuration has been improved.
143 * rrdtool plugin: Fix a possible race condition: If the network plugin

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

219 been added. Portability fixes.
220 * rrdcached plugin: This new plugin uses the (still in development)
221 RRD accelerator daemon, rrdcached. This daemon works very similar to
222 the original rrdtool plugin of collectd, but adds some more nice

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

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

292 2008-10-16, Version 4.5.1
293 * build system: Change `--enable-<plugin>' to abort with an error if
294 dependencies are not met. Thanks to Bruno Prémont for the patch.
295 Also, the poisoning of various string functions has been restricted

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

306 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
307 Linzberger for reporting the bug.

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

366 Due to a programming mistake, only 4 or 8 bytes would be copied to a
367 much larger buffer. This caused the `type' to be transferred much
368 more often than necessary. In some cases, e. g. the `cpu' and

508 * sensors plugin: Fix temperature collection with libsensors4.
509 * unixsock plugin: Fix mixed input and output operation on streams.
510 * wireless plugin: Fix reading noise value.
512 2008-03-05, Version 4.3.1
513 * exec plugin: Set supplementary group IDs.
515 + Use `memcpy' when constructing/parsing a package to avoid
516 alignment problems on weird architectures, such as Sparc.
517 + Translate doubles to/from the x86 byte representation to ensure
518 cross-platform compatibility.
519 * ping plugin: Correct the handling of the `TTL' setting.
520 * swap plugin: Reapply a patch for Solaris.
521 * tcpconns plugin: Portability improvements.
523 2008-02-18, Version 4.3.0
524 * collectd: Notifications have been added to the daemon. Notifications
525 are status messages that may be associated with a data instance.
526 * collectd: Threshold checking has been added to the daemon. This
527 means that you can configure threshold values for each data
528 instance. If this threshold is exceeded a notification will be
530 * collectd: The new `FQDNLookup' option tells the daemon to use the
531 full qualified domain name as the hostname, not just the host part
532 es returned by `gethostname(2)'.
533 * collectd: Support for more than one `TypesDB' file has been added.
534 This is useful when one such file is included in a package but one
535 wants to add custom type definitions.
536 * collectd: The `Include' config option has been expanded to handle
537 entire directories and shell wildcards.
538 * collectdmon: The new `collectdmon' binary detects when collectd
539 terminates and automatically restarts it again.
540 * csv plugin: The CSV plugin is now able to store counter values as a
541 rate, using the `StoreRates' configuration option.
542 * exec plugin: Handling of notifications has been added and the
543 ability to pass arguments to the executed programs has been added.
544 * hddtemp plugin: The new `TranslateDevicename' option lets you
545 disable the translation from device names to major-minor-numbers.
546 * logfile plugin: Handling of notifications has been added.
547 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
548 domain name lookups in this plugin.
549 * perl plugin: Many internal changes added support for handling multiple
550 threads making the plugin reasonably usable inside collectd. The API has
551 been extended to support notifications and export global variables to
552 Perl plugins; callbacks now have to be identified by name rather than a
553 pointer to a subroutine. The plugin is no longer experimental.
554 * uuid plugin: The new UUID plugin sets the hostname to an unique
555 identifier for this host. This is meant for setups where each client
556 may migrate to another physical host, possibly going through one or
557 more name changes in the process. Thanks to Richard Jones from
558 Red Hat's Emerging Technology group for this plugin.
559 * libvirt: The new libvirt plugin uses the `libvirt' library to query
560 CPU, disk and network statistics about guest systems on the same
561 physical server. Thanks to Richard Jones from Red Hat's Emerging
562 Technology group for this plugin.
564 2008-04-22, Version 4.2.7
565 * build system: Improved detection of several libraries, especially if
566 they are in non-standard paths.
567 * build system: Portability fixes: Automatically define "_REENTRANT"
568 if the libc expects it.
569 * collectd: Error and warning messages have been improved.
570 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
572 * apache plugin: Allocate new memory when reading a webpage instead of
573 using a buffer of static size.
574 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
576 * hddtemp plugin: Error and warning messages have been improved.
577 * sensors plugin: Fix sensor collection for some chip types.
579 2008-03-29, Version 4.2.6
580 * collectd: Improved error messages when parsing the configuration.
581 * sensors plugin: Fix temperature collection with libsensors4.
582 * unixsock plugin: Fix mixed input and output operation on streams.
583 * wireless plugin: Fix reading noise value.
585 2008-03-04, Version 4.2.5
586 * apache plugin: Improved initialization and error messages.
587 * exec plugin: Set supplementary group IDs.
589 + Create separate threads for reading from the socket and parsing
590 and dispatching incoming packets. Versions prior to this may have
591 problems in high-load situations, where the socket receive buffers
592 overflows, resulting in gaps in the data.
593 + Use `memcpy' when constructing/parsing a package to avoid
594 alignment problems on weird architectures, such as Sparc.
595 + Translate doubles to/from the x86 byte representation to ensure
596 cross-platform compatibility.
597 * ping plugin: Correct the handling of the `TTL' setting.
598 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
599 * swap plugin: Reapply a patch for Solaris.
600 * tcpconns plugin: Portability improvements.
602 2008-01-21, Version 4.2.4
603 * unixsock plugin: A bug in the unixsock plugin caused it not to set
604 the permission on the socket as documented in the manpage. Thanks to
605 Evgeny Chukreev for fixing this issue.
606 * collectd: The documentation has been improved.
608 2007-12-28, Version 4.2.3
609 * sensors plugin: Updated the plugin to build and work with version 3
610 of the libsensors library.
612 2007-12-15, Version 4.2.2
613 * nginx plugin: Incorrect comparison of strings lead to a segfault
614 when using the plugin. Thanks to Saulius Grigaliunas for fixing
616 * logfile plugin: The config option `Timestamp' was handled
617 incorrectly and basically always active. Thanks to Luke Heberling
620 2007-11-08, Version 4.2.1
621 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
623 * snmp plugin: Fix a memory leak.
625 2007-10-27, Version 4.2.0
626 * collectd: The new config option `Include' lets you include other
627 configfiles and thus split up your config into smaller parts. This
628 may be especially interesting for the snmp plugin to keep the data
629 definitions separate from the host definitions.
630 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
631 (number of connections, octets and packets for each service and
632 destination). Thanks to Sebastian Harl for this plugin.
633 * memcached plugin: The new `memcached' plugin connects to a memcached
634 daemon process and collects statistics of this distributed caching
635 system. Thanks to Antony Dovgal for contributing this plugin.
636 * nginx plugin: The new `nginx' plugin reads the status page of an
637 nginx daemon and saves the handled connections and requests.
638 * perl plugin: Many changes, including the added `EnableDebugger'
639 config option which lets you debug your Perl plugins more easily.
640 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
641 be more thread-safe otherwise by locking calls to the library.
642 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
643 correct the values returned by SNMP-agents. If a <data> block is
644 defined as `table' the instance is now optional. The sequence number
645 is used as the type-instance in this case. The new `InstancePrefix'
646 option allows to add arbitrary prefixes to the type-instance.
647 * tcpconns plugin: The new `tcpconns' plugin collects the number of
648 certain TCP connections and what state they're in. This can be used
649 to see how many connections your FTP server has to handle or how
650 many outgoing connections your mailserver has open.
652 2008-01-11, Version 4.1.6
653 * unixsock plugin: A bug in the unixsock plugin caused it not to set
654 the permission on the socket as documented in the manpage. Thanks to
655 Evgeny Chukreev for fixing this issue.
656 * collectd: The documentation has been improved.
658 2007-12-27, Version 4.1.5

662 of the libsensors library.
664 2007-11-08, Version 4.1.4
665 * Build system: Improve detection of the rrd library, especially if
666 it's in a non-standard location.
667 * Build system: A bug when parsing the argument for
668 `--with-libnetsnmp' has been fixed.
669 * collectd: Implement `strerror_r' if the libc doesn't provide it.
670 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
671 a deadlock or delay when shutting down the daemon.
672 * snmp plugin: Fix a memory leak.
674 2007-10-24, Version 4.1.3
675 * collectd: A build issue under Solaris has been resolved by renaming
677 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
678 be more thread-safe otherwise by locking calls to the library.
680 2007-09-28, Version 4.1.2
681 * apcups plugin: Fix reporting of the `load percent' data.
682 * wireless plugin: Correct the handling of cards returning signal and
683 noise quality as percentage.
684 * perl plugin: Fix a possible buffer overflow in get_module_name().
685 * build system: Further improve the detection of libraries.
686 * netlink plugin: Build issues under some older versions of the Linux
687 includes (i. e. Debian Sarge) have been fixed.
688 * snmp plugin: Fix a potential segfault when a host times out. Add
689 support for the `timeticks' type.

692 * Build system: The detection of `libnetlink' has been improved.
693 * collectd: The documentation has been fixed in numerous places.
694 * exec plugin: Setting the group under which to run a program has been
696 * collectd: The `sstrerror' function was improved to work correctly
697 with the broken GNU version of `strerror_r'.
698 * collectd: Write an error message to STDERR when loading of a plugin
700 * apcups plugin: Fix the `types' used to submit the values: They still
701 has an `apcups_' prefix which doesn't work anymore.
702 * rrdtool plugin: Create new RRD-files with the `begin' time set to
703 whatever the client thinks is `now'..
705 2007-09-01, Version 4.1.0
706 * Build system: The build system has been changed to automatically
707 disable all plugins, which are missing dependencies. The dependency
708 checking has been removed from the plugins themselves to remove
710 * Flexible interval: The interval of collected data is now sent along
711 with the data itself over the network, so that the interval-settings
712 of server and clients no longer needs to match.
713 * netlink plugin: The new `netlink' plugin connects to the Linux
714 kernel using a netlink socket and uses it to query information about
715 interfaces, qdiscs and classes.
716 * rrdtool plugin: The cache is now dumped to disk in an extra thread
717 to not block data collection.
718 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
719 network devices, such as switches, routers, thermometers, rack
720 monitoring servers, etc. The collectd-snmp(5) manpage documents this
722 * unixsock plugin: Added the `LISTVAL' command.
723 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
724 of music played with xmms.
726 2007-09-28, Version 4.0.9
727 * apcups plugin: Fix reporting of the `load percent' data.
728 * wireless plugin: Correct the handling of cards returning signal and
729 noise quality as percentage.
730 * perl plugin: Fix a possible buffer overflow in get_module_name().
732 2007-09-12, Version 4.0.8
733 * collectd: The `sstrerror' function was improved to work correctly
734 with the broken GNU version of `strerror_r'.
735 * collectd: Write an error message to STDERR when loading of a plugin
737 * apcups plugin: Fix the `types' used to submit the values: They still
738 has an `apcups_' prefix which doesn't work anymore.
739 * rrdtool plugin: Create new RRD-files with the `begin' time set to
740 whatever the client thinks is `now'..
742 2007-08-26, Version 4.0.7
743 * documentation: Some typos have been fixed and some information has
745 * build system: Many fixes for detecting libraries in unusual places,
746 such as on RedHat systems. The affected libraries are `libcurl',
747 `libmysql', and `libupsclient'.
748 * network plugin: Allow the `Port' option to be specified as a number
749 (i. e. without quotes).
750 * nut plugin: A fix allows linking the nut plugin against
751 libupsclient, version >= 2.2.0.
752 * processes plugin: Fix a potential segmentation fault.
754 2007-07-30, Version 4.0.6
755 * sensors plugin: Fix the ignorelist functionality: Only the `type
756 instance' was used to match against the list, but the documentation
757 told otherwise. This release fixes the code, so it complies with the
759 * syslog plugin: Call `openlog' right when the plugin is loaded, so
760 configuration messages will end up in the logging facility.
761 * conrtib/fedora: The contributed specfile for Fedora has been
764 2007-07-05, Version 4.0.5
765 * Portability: More fixes for OpenBSD have been included.
767 2007-06-24, Version 4.0.4
768 * cpu plugin: Fixed the Solaris code.
769 * dns plugin: Fixed a build issue for OpenBSD.
770 * interface plugin: Fixed the Solaris code.
771 * load plugin: Fixed the alternative `/proc' Linux code.
772 * memory plugin: Fixed the Solaris code.
773 * oconfig: Don't require `-lfl' anymore.
775 2007-06-19, Version 4.0.3
776 * cpu plugin: Fix the Darwin / Mac OS X code.
777 * ping plugin: Use the return value of `getpid', not its address.
778 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
779 initialized correctly.
780 * configure: Added `--with-nan-emulation' to aid cross compilation.
782 2007-06-12, Version 4.0.2
783 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
784 they're given in numerically form.
786 2007-06-07, Version 4.0.1
787 * iptables plugin: A bug in the configuration routine has been fixed.
788 Setting a comment in the configfile will no longer cause a
791 2007-06-03, Version 4.0.0
792 * collectd: The plugin-infrastructure has been changed to allow for
793 more types of plugins, namely `write' and `log' plugins.
794 * collectd: The read-function has been changed to read many plugins in
795 parallel, using threads. Thus, plugins generally need to use
796 thread-safe functions from now on.
797 * collectd: The '-t' command line options allows to perform syntax tests
798 of the configuration file and exit immediately.
799 * csv plugin: The new `csv' plugin handles output to `comma separated
801 * rrdtool plugin: The new `rrdtool' plugin handles output to
802 RRD-files. Data can be cached to combine multiple updates into one
803 write to increase IO-performance.
804 * network plugin: The new `network' plugin handles IO via the network.
805 It implements a different, much more extensible protocol which can
806 combine many values in one packet, decreasing the number of UDP-
807 packets being sent. It can read from and send to the network and
808 with the appropriate configuration even forward packets to other
810 * unixsock plugin: The new `unixsock' plugin provides an interface to
811 communicate with the daemon while it is running. Right now the
812 commands `GETVAL' and `PUTVAL' are implemented, but more are to
814 * perl plugin: The new `perl' plugin allows you to write extensions
815 for collectd in the scripting-language Perl.
816 * logfile plugin: The new `logfile' plugin writes logmessages to files
818 * syslog plugin: The new `syslog' plugin sends logmessages to the
819 system's syslog daemon.
820 * entropy plugin: The new `entropy' plugin collects the amount of
821 entropy currently being available to the system.
822 * exec plugin: The new `exec' plugin forks child processes and reads
823 back values provided by the forked processes.
824 * iptables plugin: The new `iptables' plugin reads counters from
825 iptables rules. Thanks to Sjoerd van der Berg for contributing this
827 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
828 to Peter Holik for contributing this plugin.
829 * nut plugin: The new `nut' plugin connects the upsd of the `network
830 ups tools' and reads information about the connected UPS.
831 * apache plugin: Support for lighttpd's `BusyServers' (aka.
832 connections) field was added by Florent Monbillard.
833 * collectd-nagios: The new `collectd-nagios' binary queries values
834 from collectd, parses them and exits according to Nagios-standards.
835 * manpages: The manpages have been improved a lot.
837 2007-09-28, Version 3.11.7
838 * wireless plugin: Correct the handling of cards returning signal and

845 * configure: Added `AC_SYS_LARGEFILE' for LFS.
846 * ntpd plugin: Fix a potential buffer overflow.
847 * processes plugin: Fix a bug when run under Linux 2.4. All processes
848 were accounted as `zombies'.
850 2007-04-10, Version 3.11.4
851 * dns plugin: Change the order of includes to make the plugin compile
854 2007-03-30, Version 3.11.3
855 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
856 of the unused `COLLECT_KSTAT'.
858 2007-02-11, Version 3.11.2
859 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
860 NULL-pointer may have been passed to `printf' which causes a
861 segfault with some libcs.
863 2007-02-10, Version 3.11.1
864 * df plugin: Some wrong defines have been fixed so the plugin works
866 * dns plugin: The usage of a struct has been fixed to work with
868 * processes plugin: Some missing defines have been added so the plugin
869 compiles cleanly under FreeBSD and presumably other UNIXes.
871 2006-12-22, Version 3.11.0
872 * collectd: The new command line option `-P' makes it easier for
873 distributors to change the location of PID-files.
874 * collectd: The daemon shuts down faster now which makes it easier to
875 write init.d-scripts for it.
876 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
877 caused problems every now and then.
878 * df plugin: New config options allow to ignore certain mountpoints,
879 filesystem types or devices.
880 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
881 and interprets it. It collects traffic as well as qtype, opcode and
883 * email plugin: Sebastian Harl has contributed this plugin which
884 counts received mails in categories (e. g. ham, spam, virus), spam
885 score (as given by SpamAssassin) and check types.
886 * mbmon plugin: Flavio Stanchina has contributed this plugin which
887 uses `mbmon' to gather information from sensors on the motherboard.
888 * processes plugin: Collect detailed statistics for configured
889 processes, that's process and thread count, CPU usage, resident
890 segment size and pagefaults.
891 * multimeter plugin: Peter Holik contributed a new plugin which
893 * sensors plugin: Lubos Stanek has put much effort into improving this
894 plugin, including `extended naming', collection of voltage values
895 and the possibility to ignore certain values.
897 2006-12-21, Version 3.10.4
898 * Max Kellermann has identified a bug in the server routine: When
899 opening a socket fails the daemon will (re)try opening the socket in
900 an endless loop, ultimately leading to a `EMFILE' error.
902 2006-11-04, Version 3.10.3
903 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
904 ntpd's reply was sent in more than one packet, the buffer size was
905 calculated incorrectly, resulting in the reading of uninitialized or
908 2006-11-01, Version 3.10.2
909 * The sample config file has been improved.
910 * Errors in the manpages have been corrected.
911 * The ping-plugin now adds hosts during initialization, not during
912 startup. This speeds up startup when no network connectivity is
913 available. Also, the hosts are being added later when the network is
915 * Improved BSD-support for the df-plugin.
916 * Fixed syntax errors in the swap-plugin for Mac OS X.
917 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
919 * Don't disable the mysql-plugin if connecting to the database fails
920 during initialization. Instead, try again in increasing intervals.
922 2006-07-19, Version 3.10.1
923 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
924 the apcups cannot be reached, unconnected sockets will pile up and
925 eventually lead to `Too many open files' errors.
927 2006-07-09, Version 3.10.0
928 * The `disk' plugin has been ported to Darwin.
929 * The `battery' plugin should work on many Apple computers now.
930 * The `traffic' plugin can now ignore certain interfaces. Also,
931 statistics for sent/received packets and errors have been added.
932 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
933 to Anthony Gialluca for contributing this plugin and providing me
934 with a test environment :)
935 * A plugin for monitoring an NTP instance and the local clock drift
938 2006-06-25, Version 3.9.4
939 * The Solaris code in the `swap' plugin has been changed to reflect
940 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
942 * The debugging system has been fixed to work with the Sun libc.
943 * When built without librrd the variable `operating_mode' could be
944 uninitialized. Thanks to David Elliot for reporting the bug.
946 2006-06-01, Version 3.9.3
947 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
948 operating systems also profit from the changes, but I wasn't able to
950 * Changed the build system to find the netinet-includes under FreeBSD
951 and therefore successfully build the `liboping' library there.
953 2006-05-09, Version 3.9.2
954 * Applied a patch to the `liboping' library. Due to a bug in the
955 sequence checking the `ping' plugin stopped working after
956 approximately 7.6 days.
958 2006-05-09, Version 3.8.5
959 * Applied a patch to the `liboping' library. Due to a bug in the
960 sequence checking the `ping' plugin stopped working after
961 approximately 7.6 days.
963 2006-04-21, Version 3.9.1
964 * Build issues with Solaris and possible other architectures have been
966 * Problems when building the `apache'-plugin without `libcurl' have
968 * A bug in the `ping' plugin has been fixed. Sorry folks.
970 2006-04-02, Version 3.9.0
971 * A plugin to monitor the Apache webserver has been added.
972 <http://httpd.apache.org/>
973 * A plugin to collect statistics about virtual servers using VServer.
974 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
976 * A plugin for wireless LAN cards has been added. It monitors signal
977 strength, link quality and noise ratio..
978 * A plugin for Apple hardware sensors has been added.
979 * An option to compile collectd with different `step' and `heartbeat'
980 settings has been added. The size of RRAs is no longer static but
981 calculated based on the settings for `step' and `width'.
982 * The `ping' plugin can now be configured to use a certain TTL.
983 * A plugin to monitor the hardware sensors of Apple computers has been
985 * The plugins `cpu', `memory', `processes' and `traffic' have been
986 ported to Mach/Darwin (Mac OS X).
987 * The `log mode' has been contributed by Christophe Kalt. It writes
988 the data into text files rather than RRD files.
990 2006-04-09, Version 3.8.4
991 * Applied patch by Vincent Stehlé which improves the disk-name
992 resolution in the `hddtemp' plugin for Linux systems.
994 2006-04-02, Version 3.8.3
995 * Applied a patch by James Byers: The MySQL plugin was not working
996 with MySQL 5.0.2 or later.
998 2006-03-14, Version 3.8.2
999 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1000 the GNU libc, because it points to `/etc/fstab' rather than
1003 2006-03-13, Version 3.8.1
1004 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1005 * Fixes in the debian `postinst' and `init.d' scripts.
1007 2006-03-09, Version 3.8.0
1008 * The `ping' plugin no longer uses `libping' but a self written
1009 library named `liboping'. With this library it's possible to ping
1010 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1012 2006-02-18, Version 3.7.2
1013 * A simple bug in the `battery' plugin has been fixed. It should now
1014 work with ACPI based batteries as well. Thanks to Sebastian for
1016 * Fixing a bug that prevented collectd to be built without librrd.
1017 Thanks to Werner Heuser for reporting it.
1019 2006-02-04, Version 3.7.1
1020 * The new network code has been improved to build with older versions
1022 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1023 to Tommie Gannert for this patch.
1025 2006-01-30, Version 3.7.0
1026 * The `battery' plugin has been added. It collects information about
1028 * The MySQL plugin has been improved: It now writes two more RRD
1029 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1030 * The `cpufreq' plugin now reads another file since the file it did
1031 read so far causes much overhead in the kernel. Also, you need root
1032 to read the old file, but not to read the new one.
1033 * The `hddtemp' plugin can now be configured to connect to another
1034 address and/or port than localhost.
1035 * The `df' plugin now prefers `statvfs' over `statfs'.
1036 * The network code has been rewritten. collectd now supports unicast
1037 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1038 be set in the configfile.
1040 2006-01-24, Version 3.6.2
1041 * Due to a bug in the configfile handling collectd wouldn't start in
1042 client mode. This released fixes this.
1044 2006-01-20, Version 3.6.1
1045 * Due to a bug in `configure.in' all modules and the binary were
1046 linked against `libmysqlclient'. This issue is solved by this
1049 2006-01-17, Version 3.6.0
1050 * A config file has been added. This allows for loading only specific
1052 * A `df' plugin has been added.
1053 * A `mysql' plugin has been added.
1054 * The `ping' plugin doesn't entirely give up hope when a socket error
1055 occurred, but will back of and increase the intervals between tries.
1057 2006-01-21, Version 3.5.2
1058 * Fixed yet another bug in the signal handling.. Stupid typo..
1059 * Improved the ping plugin to not give up on socket errors (backport
1062 2005-12-18, Version 3.5.1
1063 * The PID-file is now deleted correctly when shutting down the daemon.
1064 * SIGINT and SIGTERM are now handled correctly.
1066 2005-12-16, Version 3.5.0 (Revision 326)
1067 * A bug in the `load' module under Solaris has been fixed.
1068 * The `users' module has been contributed by Sebastian Harl. It counts
1069 currently logged in users.
1070 * The CPU module now works under FreeBSD without the use of
1071 `libstatgrab', however SMP support is missing.
1072 * The default directories for the RRD files and the PID file now
1073 depend on the compile time setting of `localstatedir'.
1075 2005-11-15, Version 3.4.0 (Revision 236)
1076 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1077 from gentoo's bugzilla for writing the patch.
1078 * The build dependency for librrd has been removed. Binaries built
1079 without librrd are client-only and will multicast their value as
1080 with the `-c' argument.
1081 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1082 * The newly introduced `-f' switch prevents daemon initialization
1083 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1084 Barcellos for this patch.
1086 2005-11-04, Version 3.3.0 (Revision 216)
1087 * New modules have been added:
1088 - `serial', for monitoring traffic on the serial interfaces
1089 - `nfs', for graphing NFS procedure calls
1090 - `tape', traffic from/to tape devices
1091 * The memory.rrd now accepts more than 4Gig of memory.
1093 2005-10-26, Version 3.2.0 (Revision 200)
1094 * Support for graphing the processes has been added (thanks to Lyonel
1096 * If reading from hddtemp fails collectd will increase the time
1097 between polls up to one day.
1098 * The init.d files have been improved.
1099 * Problems with the spec file have been fixed.
1101 2005-10-16, Version 3.1.0 (Revision 194)
1102 * Added the `setsid' syscall to the startup code.
1103 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1105 2005-09-30, Version 3.0.0 (Revision 184)
1106 * The ability to send/receive data to/from the network (think
1107 multicast) has been added.
1108 * Modules have been split up into shared libraries can be loaded at
1109 runtime. The biggest advantage is that the core program doesn't need
1110 to be linked against an external library.
1111 * A patch by George Kargiotakis has been applied: It fixes the sensors
1112 behaviour then more than one sensor is being queried.
1114 2005-09-16, Version 2.1.0 (Revision 172)
1115 * A module for swap statistics has been added.
1117 2005-09-09, Version 2.0.0 (Revision 135)
1118 * Filenames can no longer be configured at program startup. The only
1119 options as of this version are the directory and ping hosts.
1120 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1121 Soft-IRQ statistics are added to `System'.
1122 * Diskstats now collect read and write bytes, not sectors.
1123 * Ping statistics can now be collected for more than one host. There
1124 is no default any more: If no host is given no host will be pinged.
1125 * A self-written patch for libping has been applied so it builds
1128 2005-09-01, Version 1.8.1 (Revision 123)
1129 * Much improved configure-script: libraries and features may now be
1131 * More detailed warnings/error messages when RRD update fails.
1133 2005-08-29, Version 1.8.0:
1134 * Support for collecting disk statistics under Solaris.
1136 2005-08-25, Version 1.7.0:
1137 * Support for libstatgrab[1] for load, memory usage and network
1138 traffic. CPU- and disk-usage are not (yet) supported, since
1139 libstatgrab returns insufficient information. I will contact the
1141 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1142 aren't necessarily counted linear which is now handled correctly.
1143 [1]: http://www.i-scream.org/libstatgrab/
1145 2005-08-21, Version 1.6.0:
1146 * Basic support for Solaris: System load and cpu-usage can be
1147 collected under Solaris, too. Other stats will follow later.
1148 * Many fixes in the autoconf-script
1149 * Collection/Museum scripts have been added under contrib/museum
1150 * collectd may now be started in unprivileged mode, though ping
1151 statistics will not work.
1153 2005-07-17, Version 1.5.1:
1154 * Diskstats-RRDs now use major/minor for naming. Some systems have
1155 weird strings as disk-names..
1157 2005-07-17, Version 1.5:
1158 * A new module, diskstats, has been added. It collects information
1159 about the disks and partitions.
1161 2005-07-11, Version 1.4.2:
1162 * The meminfo module has been changed to work with more platforms
1163 and/or kernel versions.
1165 2005-07-10, Version 1.4.1: Correct traffic stats
1166 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1167 forgot to correct when I changed that module.
1169 2005-07-09, Version 1.4: More traffic stats
1170 * Traffic is now collected for all interfaces that can be found
1171 * Temperature-statistics are read from lm-sensors if available
1173 2005-07-08, Version 1.3: CPU stats
1174 * Collecting CPU statistics now
1176 2005-07-12, Version 1.2: Using syslog
1177 * collectd is now using the syslog facility to report errors, warnings
1179 * The default directory is now /var/db/collectd
1181 2005-07-10, Version 1.1: Minor changes
1182 * Nothing really useful to say ;)
1184 2005-07-09, Version 1.0: Initial Version
1185 * The following modules are provided:
