25 Aman Gupta for the patch.
26 * olsrd plugin: The new OLSRd plugin queries routing information from
27 the “Optimized Link State Routing” daemon.
28 * rrdtool plugin: A new configuration option allows to define a random
29 write delay when writing RRD files. This spreads the load created by
30 writing RRD files more evenly. Thanks to Mariusz Gronczewski for the
32 * swap plugin: The possibility to collect swapped in/out pages has
33 been added to the Swap plugin. Thanks to Stefan Völkel for the

68 forked. The JVM internally creates threads that are lost when
69 forking. This means that Java-based plugins are now configured
70 during the init-phase, i. e. later than other plugins.
71 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
72 to Alan Pevec for the patch.
73 * network plugin: Fix the handling of the “CacheFlush” option: The

215 name which prevented this match to be used as documented. Thanks to
216 Bruno Prémont for finding this problem.
217 * bind plugin: Fix collection of the cached RR sets. The number of RR
218 sets currently in the cache was collected as a counter value, which
219 is nonsense. Thanks to Bruno Prémont for implementing this.
220 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
221 primarily BSDs, don't take it well and crash.
222 * oracle plugin: Portability to 64 bit systems has been improved.
223 * postgresql plugin: The default configuration has been improved.
224 * rrdtool plugin: Fix a possible race condition: If the network plugin

239 user to use `matches' and `targets' to control value processing.
240 * collectd: The new `-T' command line argument allows more in-depth
241 testing of a configuration. Thanks to Doug MacEachern for the patch.
242 * collectd-nagios: The Nagios integration command has been updated to
243 use libcollectdclient. The `percentage' aggregation function has

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

299 * processes plugin: Stacksize and virtual memory usage statistics have
300 been added. Portability fixes.
301 * rrdcached plugin: This new plugin uses the (still in development)
302 RRD accelerator daemon, rrdcached. This daemon works very similar to
303 the original rrdtool plugin of collectd, but adds some more nice

343 file may be in both locations, especially when the database was
344 installed in a non-standard path. Thanks to Dusty Doris for
346 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
347 Solaris, in the configure script automatically.
348 * build system, tcpconns plugin: Check for `kvm_nlist' and
349 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM

358 * filecount plugin: Fix an off-by-one error. This error may cause a
360 * network plugin: Fix the handling of `type' in the network protocol.
361 Due to a programming mistake, only 4 or 8 bytes would be copied to a
362 much larger buffer. This caused the `type' to be transferred much
363 more often than necessary. In some cases, e. g. the `cpu' and
364 `cpufreq' plugins being used at the same time, data may be corrupted
365 in those files. Thanks to Bruno Prémont for debugging and reporting
367 * processes plugin: Fix a possible segmentation fault when specifying
368 invalid configuration options.
369 * unixsock plugin: Make sure the initialization function is run only

373 2008-10-16, Version 4.5.1
374 * build system: Change `--enable-<plugin>' to abort with an error if
375 dependencies are not met. Thanks to Bruno Prémont for the patch.
376 Also, the poisoning of various string functions has been restricted

380 leak in the configuration handling code has been fixed. Thanks to
381 Niraj Tolia for reporting these issues.
382 * collectd: Fix an off-by-one error in the ignorelist functionality.
383 When using regular expressions, the last character would be missing,
384 possibly matching differently from what one would expect.
385 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
387 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
388 Linzberger for reporting the bug.
389 * iptables plugin: Fix an off-by-one error. If a string was just one
390 character too long, it was truncated instead of reporting an error.
391 * network plugin: Fix a memory leak in the configuration handling
392 code. Thanks to Niraj Tolia for reporting this issue.
393 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

495 * network plugin: Bugfix in the init routine: The init function
496 cleared a buffer regardless of its contents. This could lead to lost
497 values under Solaris.
498 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
499 * vserver plugin: Remove usage of the thread-unsafe `readdir'
501 * wireless plugin: Work around incorrect noise and power values
502 returned by some broken drivers.
504 2008-06-03, Version 4.4.1
505 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
506 to kyrone for reporting this.
507 * collectd: Fixed min/max output in notifications generated by
509 * collectd-nagios: Fix the protocol used to communicate with the
511 * perl plugin: Fail noisily, but don't shutdown the daemon, if
512 initialization has errors. An issue with Perl 5.10 has been fixed.
513 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
514 René Rebe and Siegmund Gorr for reporting this.
516 2008-05-06, Version 4.4.0
517 * collectd: Internal code cleanups.
518 * collectd: Added support for a `Flush' command in the unixsock and
519 exec plugins. This command can be used to force a plugin (or all) to
520 flush its values to disk.
521 * collectd: Thresholds can now be configured to apply to one data
522 source only, making it possible to configure different thresholds
523 for each data source.
524 * apache, nginx plugins: Added the possibility to disable host and/or
526 * ascent plugin: The new ascent plugin reads and parses the statistics
527 page of an Ascent server.
528 * cpu plugin: Support for the statgrab library has been added.
529 * disk plugin: The possibility to ignore certain disks or collect only
530 specific disks has been added.
531 * disk plugin: Support for the statgrab library has been added.
532 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
533 sensor values via IPMI, the intelligent platform management
535 * iptables plugin: The iptc library that is used by the iptables
536 plugin has been added to the distribution, because it is not
537 provided by all distributions and removed from at least one.
538 * powerdns plugin: The new powerdns plugin reads statistics from an
539 authoritative or a recursing PowerDNS name server.
540 * rrdtool plugin: The size of the files generated with the default
541 configuration has been decreased.
542 * tail plugin: The new tail plugin can be used to gather statistics by
543 continuously reading from log files.
544 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
545 TeamSpeak2 server and collects statistics about the number of users
546 and number of channels.
547 * users plugin: Support for the statgrab library has been added.
548 * vmem plugin: The new vmem plugin collects very detailed statistics
549 about the virtual memory subsystem of Linux.

561 * memory plugin: A typo in the libstatgrab code has been fixed.
562 * network plugin: A fix in the initialization function solves problems
564 * nginx plugin: A thread-unsafe function has been replaced.
565 * vserver plugin: A thread-unsafe function has been replaced.
566 * wireless plugin: A work-around for broken wireless drivers has been
569 2008-04-22, Version 4.3.3
570 * build system: Improved detection of several libraries, especially if
571 they are in non-standard paths.
572 * build system: Portability fixes: Automatically define "_REENTRANT"
573 if the libc expects it.
574 * collectd: Error and warning messages have been improved.
575 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
577 * apache plugin: Allocate new memory when reading a webpage instead of
578 using a buffer of static size.
579 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
581 * hddtemp plugin: Error and warning messages have been improved.
582 * sensors plugin: Fix sensor collection for some chip types.
584 2008-03-29, Version 4.3.2
585 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
586 `Persist' threshold options.
587 * collectd: Fix handling of missing values in the global value cache.
588 * collectd: Improved error messages when parsing the configuration.
589 * sensors plugin: Fix temperature collection with libsensors4.
590 * unixsock plugin: Fix mixed input and output operation on streams.
591 * wireless plugin: Fix reading noise value.
593 2008-03-05, Version 4.3.1
594 * exec plugin: Set supplementary group IDs.
596 + Use `memcpy' when constructing/parsing a package to avoid
597 alignment problems on weird architectures, such as Sparc.
598 + Translate doubles to/from the x86 byte representation to ensure
599 cross-platform compatibility.
600 * ping plugin: Correct the handling of the `TTL' setting.
601 * swap plugin: Reapply a patch for Solaris.
602 * tcpconns plugin: Portability improvements.
604 2008-02-18, Version 4.3.0
605 * collectd: Notifications have been added to the daemon. Notifications
606 are status messages that may be associated with a data instance.
607 * collectd: Threshold checking has been added to the daemon. This
608 means that you can configure threshold values for each data
609 instance. If this threshold is exceeded a notification will be
611 * collectd: The new `FQDNLookup' option tells the daemon to use the
612 full qualified domain name as the hostname, not just the host part
613 es returned by `gethostname(2)'.
614 * collectd: Support for more than one `TypesDB' file has been added.
615 This is useful when one such file is included in a package but one
616 wants to add custom type definitions.
617 * collectd: The `Include' config option has been expanded to handle
618 entire directories and shell wildcards.
619 * collectdmon: The new `collectdmon' binary detects when collectd
620 terminates and automatically restarts it again.
621 * csv plugin: The CSV plugin is now able to store counter values as a
622 rate, using the `StoreRates' configuration option.
623 * exec plugin: Handling of notifications has been added and the
624 ability to pass arguments to the executed programs has been added.
625 * hddtemp plugin: The new `TranslateDevicename' option lets you
626 disable the translation from device names to major-minor-numbers.
627 * logfile plugin: Handling of notifications has been added.
628 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
629 domain name lookups in this plugin.
630 * perl plugin: Many internal changes added support for handling multiple
631 threads making the plugin reasonably usable inside collectd. The API has
632 been extended to support notifications and export global variables to
633 Perl plugins; callbacks now have to be identified by name rather than a
634 pointer to a subroutine. The plugin is no longer experimental.
635 * uuid plugin: The new UUID plugin sets the hostname to an unique
636 identifier for this host. This is meant for setups where each client
637 may migrate to another physical host, possibly going through one or
638 more name changes in the process. Thanks to Richard Jones from
639 Red Hat's Emerging Technology group for this plugin.
640 * libvirt: The new libvirt plugin uses the `libvirt' library to query
641 CPU, disk and network statistics about guest systems on the same
642 physical server. Thanks to Richard Jones from Red Hat's Emerging
643 Technology group for this plugin.
645 2008-04-22, Version 4.2.7
646 * build system: Improved detection of several libraries, especially if
647 they are in non-standard paths.
648 * build system: Portability fixes: Automatically define "_REENTRANT"
649 if the libc expects it.
650 * collectd: Error and warning messages have been improved.
651 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
653 * apache plugin: Allocate new memory when reading a webpage instead of
654 using a buffer of static size.
655 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
657 * hddtemp plugin: Error and warning messages have been improved.
658 * sensors plugin: Fix sensor collection for some chip types.
660 2008-03-29, Version 4.2.6
661 * collectd: Improved error messages when parsing the configuration.
662 * sensors plugin: Fix temperature collection with libsensors4.
663 * unixsock plugin: Fix mixed input and output operation on streams.
664 * wireless plugin: Fix reading noise value.
666 2008-03-04, Version 4.2.5
667 * apache plugin: Improved initialization and error messages.
668 * exec plugin: Set supplementary group IDs.
670 + Create separate threads for reading from the socket and parsing
671 and dispatching incoming packets. Versions prior to this may have
672 problems in high-load situations, where the socket receive buffers
673 overflows, resulting in gaps in the data.
674 + Use `memcpy' when constructing/parsing a package to avoid
675 alignment problems on weird architectures, such as Sparc.
676 + Translate doubles to/from the x86 byte representation to ensure
677 cross-platform compatibility.
678 * ping plugin: Correct the handling of the `TTL' setting.
679 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
680 * swap plugin: Reapply a patch for Solaris.
681 * tcpconns plugin: Portability improvements.
683 2008-01-21, Version 4.2.4
684 * unixsock plugin: A bug in the unixsock plugin caused it not to set
685 the permission on the socket as documented in the manpage. Thanks to
686 Evgeny Chukreev for fixing this issue.
687 * collectd: The documentation has been improved.
689 2007-12-28, Version 4.2.3
690 * sensors plugin: Updated the plugin to build and work with version 3
691 of the libsensors library.
693 2007-12-15, Version 4.2.2
694 * nginx plugin: Incorrect comparison of strings lead to a segfault
695 when using the plugin. Thanks to Saulius Grigaliunas for fixing
697 * logfile plugin: The config option `Timestamp' was handled
698 incorrectly and basically always active. Thanks to Luke Heberling
701 2007-11-08, Version 4.2.1
702 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
704 * snmp plugin: Fix a memory leak.
706 2007-10-27, Version 4.2.0
707 * collectd: The new config option `Include' lets you include other
708 configfiles and thus split up your config into smaller parts. This
709 may be especially interesting for the snmp plugin to keep the data
710 definitions separate from the host definitions.
711 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
712 (number of connections, octets and packets for each service and
713 destination). Thanks to Sebastian Harl for this plugin.
714 * memcached plugin: The new `memcached' plugin connects to a memcached
715 daemon process and collects statistics of this distributed caching
716 system. Thanks to Antony Dovgal for contributing this plugin.
717 * nginx plugin: The new `nginx' plugin reads the status page of an
718 nginx daemon and saves the handled connections and requests.
719 * perl plugin: Many changes, including the added `EnableDebugger'
720 config option which lets you debug your Perl plugins more easily.
721 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
722 be more thread-safe otherwise by locking calls to the library.
723 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
724 correct the values returned by SNMP-agents. If a <data> block is
725 defined as `table' the instance is now optional. The sequence number
726 is used as the type-instance in this case. The new `InstancePrefix'
727 option allows to add arbitrary prefixes to the type-instance.
728 * tcpconns plugin: The new `tcpconns' plugin collects the number of
729 certain TCP connections and what state they're in. This can be used
730 to see how many connections your FTP server has to handle or how
731 many outgoing connections your mailserver has open.
733 2008-01-11, Version 4.1.6
734 * unixsock plugin: A bug in the unixsock plugin caused it not to set
735 the permission on the socket as documented in the manpage. Thanks to
736 Evgeny Chukreev for fixing this issue.
737 * collectd: The documentation has been improved.
739 2007-12-27, Version 4.1.5

747 it's in a non-standard location.
748 * Build system: A bug when parsing the argument for
749 `--with-libnetsnmp' has been fixed.
750 * collectd: Implement `strerror_r' if the libc doesn't provide it.
751 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
752 a deadlock or delay when shutting down the daemon.
753 * snmp plugin: Fix a memory leak.
755 2007-10-24, Version 4.1.3
756 * collectd: A build issue under Solaris has been resolved by renaming
758 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
759 be more thread-safe otherwise by locking calls to the library.
761 2007-09-28, Version 4.1.2
762 * apcups plugin: Fix reporting of the `load percent' data.
763 * wireless plugin: Correct the handling of cards returning signal and
764 noise quality as percentage.
765 * perl plugin: Fix a possible buffer overflow in get_module_name().
766 * build system: Further improve the detection of libraries.
767 * netlink plugin: Build issues under some older versions of the Linux
768 includes (i. e. Debian Sarge) have been fixed.
769 * snmp plugin: Fix a potential segfault when a host times out. Add
770 support for the `timeticks' type.
772 2007-09-12, Version 4.1.1
773 * Build system: The detection of `libnetlink' has been improved.
774 * collectd: The documentation has been fixed in numerous places.
775 * exec plugin: Setting the group under which to run a program has been
777 * collectd: The `sstrerror' function was improved to work correctly
778 with the broken GNU version of `strerror_r'.
779 * collectd: Write an error message to STDERR when loading of a plugin
781 * apcups plugin: Fix the `types' used to submit the values: They still
782 has an `apcups_' prefix which doesn't work anymore.
783 * rrdtool plugin: Create new RRD-files with the `begin' time set to
784 whatever the client thinks is `now'..
786 2007-09-01, Version 4.1.0
787 * Build system: The build system has been changed to automatically
788 disable all plugins, which are missing dependencies. The dependency
789 checking has been removed from the plugins themselves to remove
791 * Flexible interval: The interval of collected data is now sent along
792 with the data itself over the network, so that the interval-settings
793 of server and clients no longer needs to match.
794 * netlink plugin: The new `netlink' plugin connects to the Linux
795 kernel using a netlink socket and uses it to query information about
796 interfaces, qdiscs and classes.
797 * rrdtool plugin: The cache is now dumped to disk in an extra thread
798 to not block data collection.
799 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
800 network devices, such as switches, routers, thermometers, rack
801 monitoring servers, etc. The collectd-snmp(5) manpage documents this
803 * unixsock plugin: Added the `LISTVAL' command.
804 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
805 of music played with xmms.
807 2007-09-28, Version 4.0.9
808 * apcups plugin: Fix reporting of the `load percent' data.
809 * wireless plugin: Correct the handling of cards returning signal and
810 noise quality as percentage.
811 * perl plugin: Fix a possible buffer overflow in get_module_name().
813 2007-09-12, Version 4.0.8
814 * collectd: The `sstrerror' function was improved to work correctly
815 with the broken GNU version of `strerror_r'.
816 * collectd: Write an error message to STDERR when loading of a plugin
818 * apcups plugin: Fix the `types' used to submit the values: They still
819 has an `apcups_' prefix which doesn't work anymore.
820 * rrdtool plugin: Create new RRD-files with the `begin' time set to
821 whatever the client thinks is `now'..
823 2007-08-26, Version 4.0.7
824 * documentation: Some typos have been fixed and some information has
826 * build system: Many fixes for detecting libraries in unusual places,
827 such as on RedHat systems. The affected libraries are `libcurl',
828 `libmysql', and `libupsclient'.
829 * network plugin: Allow the `Port' option to be specified as a number
830 (i. e. without quotes).
831 * nut plugin: A fix allows linking the nut plugin against
832 libupsclient, version >= 2.2.0.
833 * processes plugin: Fix a potential segmentation fault.
835 2007-07-30, Version 4.0.6
836 * sensors plugin: Fix the ignorelist functionality: Only the `type
837 instance' was used to match against the list, but the documentation
838 told otherwise. This release fixes the code, so it complies with the
840 * syslog plugin: Call `openlog' right when the plugin is loaded, so
841 configuration messages will end up in the logging facility.
842 * conrtib/fedora: The contributed specfile for Fedora has been
845 2007-07-05, Version 4.0.5
846 * Portability: More fixes for OpenBSD have been included.
848 2007-06-24, Version 4.0.4
849 * cpu plugin: Fixed the Solaris code.
850 * dns plugin: Fixed a build issue for OpenBSD.
851 * interface plugin: Fixed the Solaris code.
852 * load plugin: Fixed the alternative `/proc' Linux code.

854 * oconfig: Don't require `-lfl' anymore.
856 2007-06-19, Version 4.0.3
857 * cpu plugin: Fix the Darwin / Mac OS X code.
858 * ping plugin: Use the return value of `getpid', not its address.

860 initialized correctly.
861 * configure: Added `--with-nan-emulation' to aid cross compilation.
863 2007-06-12, Version 4.0.2
864 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
865 they're given in numerically form.
867 2007-06-07, Version 4.0.1
868 * iptables plugin: A bug in the configuration routine has been fixed.
869 Setting a comment in the configfile will no longer cause a
872 2007-06-03, Version 4.0.0
873 * collectd: The plugin-infrastructure has been changed to allow for
874 more types of plugins, namely `write' and `log' plugins.
875 * collectd: The read-function has been changed to read many plugins in
876 parallel, using threads. Thus, plugins generally need to use
877 thread-safe functions from now on.
878 * collectd: The '-t' command line options allows to perform syntax tests
879 of the configuration file and exit immediately.
880 * csv plugin: The new `csv' plugin handles output to `comma separated
882 * rrdtool plugin: The new `rrdtool' plugin handles output to
883 RRD-files. Data can be cached to combine multiple updates into one
884 write to increase IO-performance.
885 * network plugin: The new `network' plugin handles IO via the network.
886 It implements a different, much more extensible protocol which can
887 combine many values in one packet, decreasing the number of UDP-
888 packets being sent. It can read from and send to the network and
889 with the appropriate configuration even forward packets to other
891 * unixsock plugin: The new `unixsock' plugin provides an interface to
892 communicate with the daemon while it is running. Right now the
893 commands `GETVAL' and `PUTVAL' are implemented, but more are to
895 * perl plugin: The new `perl' plugin allows you to write extensions
896 for collectd in the scripting-language Perl.
897 * logfile plugin: The new `logfile' plugin writes logmessages to files
899 * syslog plugin: The new `syslog' plugin sends logmessages to the
900 system's syslog daemon.
901 * entropy plugin: The new `entropy' plugin collects the amount of
902 entropy currently being available to the system.
903 * exec plugin: The new `exec' plugin forks child processes and reads
904 back values provided by the forked processes.
905 * iptables plugin: The new `iptables' plugin reads counters from
906 iptables rules. Thanks to Sjoerd van der Berg for contributing this
908 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
909 to Peter Holik for contributing this plugin.
910 * nut plugin: The new `nut' plugin connects the upsd of the `network
911 ups tools' and reads information about the connected UPS.
912 * apache plugin: Support for lighttpd's `BusyServers' (aka.
913 connections) field was added by Florent Monbillard.
914 * collectd-nagios: The new `collectd-nagios' binary queries values
915 from collectd, parses them and exits according to Nagios-standards.
916 * manpages: The manpages have been improved a lot.
918 2007-09-28, Version 3.11.7
919 * wireless plugin: Correct the handling of cards returning signal and

926 * configure: Added `AC_SYS_LARGEFILE' for LFS.
927 * ntpd plugin: Fix a potential buffer overflow.
928 * processes plugin: Fix a bug when run under Linux 2.4. All processes
929 were accounted as `zombies'.
931 2007-04-10, Version 3.11.4
932 * dns plugin: Change the order of includes to make the plugin compile
935 2007-03-30, Version 3.11.3
936 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
937 of the unused `COLLECT_KSTAT'.
939 2007-02-11, Version 3.11.2
940 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
941 NULL-pointer may have been passed to `printf' which causes a
942 segfault with some libcs.
944 2007-02-10, Version 3.11.1
945 * df plugin: Some wrong defines have been fixed so the plugin works
947 * dns plugin: The usage of a struct has been fixed to work with
949 * processes plugin: Some missing defines have been added so the plugin
950 compiles cleanly under FreeBSD and presumably other UNIXes.
952 2006-12-22, Version 3.11.0
953 * collectd: The new command line option `-P' makes it easier for
954 distributors to change the location of PID-files.
955 * collectd: The daemon shuts down faster now which makes it easier to
956 write init.d-scripts for it.
957 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
958 caused problems every now and then.
959 * df plugin: New config options allow to ignore certain mountpoints,
960 filesystem types or devices.
961 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
962 and interprets it. It collects traffic as well as qtype, opcode and
964 * email plugin: Sebastian Harl has contributed this plugin which
965 counts received mails in categories (e. g. ham, spam, virus), spam
966 score (as given by SpamAssassin) and check types.
967 * mbmon plugin: Flavio Stanchina has contributed this plugin which
968 uses `mbmon' to gather information from sensors on the motherboard.
969 * processes plugin: Collect detailed statistics for configured
970 processes, that's process and thread count, CPU usage, resident
971 segment size and pagefaults.
972 * multimeter plugin: Peter Holik contributed a new plugin which
974 * sensors plugin: Lubos Stanek has put much effort into improving this
975 plugin, including `extended naming', collection of voltage values
976 and the possibility to ignore certain values.
978 2006-12-21, Version 3.10.4
979 * Max Kellermann has identified a bug in the server routine: When
980 opening a socket fails the daemon will (re)try opening the socket in
981 an endless loop, ultimately leading to a `EMFILE' error.
983 2006-11-04, Version 3.10.3
984 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
985 ntpd's reply was sent in more than one packet, the buffer size was
986 calculated incorrectly, resulting in the reading of uninitialized or
989 2006-11-01, Version 3.10.2
990 * The sample config file has been improved.
991 * Errors in the manpages have been corrected.
992 * The ping-plugin now adds hosts during initialization, not during
993 startup. This speeds up startup when no network connectivity is
994 available. Also, the hosts are being added later when the network is
996 * Improved BSD-support for the df-plugin.
997 * Fixed syntax errors in the swap-plugin for Mac OS X.
998 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1000 * Don't disable the mysql-plugin if connecting to the database fails
1001 during initialization. Instead, try again in increasing intervals.
1003 2006-07-19, Version 3.10.1
1004 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1005 the apcups cannot be reached, unconnected sockets will pile up and
1006 eventually lead to `Too many open files' errors.
1008 2006-07-09, Version 3.10.0
1009 * The `disk' plugin has been ported to Darwin.
1010 * The `battery' plugin should work on many Apple computers now.
1011 * The `traffic' plugin can now ignore certain interfaces. Also,
1012 statistics for sent/received packets and errors have been added.

1019 2006-06-25, Version 3.9.4
1020 * The Solaris code in the `swap' plugin has been changed to reflect
1021 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1023 * The debugging system has been fixed to work with the Sun libc.
1024 * When built without librrd the variable `operating_mode' could be
1025 uninitialized. Thanks to David Elliot for reporting the bug.
1027 2006-06-01, Version 3.9.3
1028 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1029 operating systems also profit from the changes, but I wasn't able to
1031 * Changed the build system to find the netinet-includes under FreeBSD
1032 and therefore successfully build the `liboping' library there.
1034 2006-05-09, Version 3.9.2
1035 * Applied a patch to the `liboping' library. Due to a bug in the
1036 sequence checking the `ping' plugin stopped working after
1037 approximately 7.6 days.
1039 2006-05-09, Version 3.8.5
1040 * Applied a patch to the `liboping' library. Due to a bug in the
1041 sequence checking the `ping' plugin stopped working after
1042 approximately 7.6 days.
1044 2006-04-21, Version 3.9.1
1045 * Build issues with Solaris and possible other architectures have been
1047 * Problems when building the `apache'-plugin without `libcurl' have
1049 * A bug in the `ping' plugin has been fixed. Sorry folks.
1051 2006-04-02, Version 3.9.0
1052 * A plugin to monitor the Apache webserver has been added.
1053 <http://httpd.apache.org/>
1054 * A plugin to collect statistics about virtual servers using VServer.
1055 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1057 * A plugin for wireless LAN cards has been added. It monitors signal
1058 strength, link quality and noise ratio..
1059 * A plugin for Apple hardware sensors has been added.
1060 * An option to compile collectd with different `step' and `heartbeat'
1061 settings has been added. The size of RRAs is no longer static but
1062 calculated based on the settings for `step' and `width'.
1063 * The `ping' plugin can now be configured to use a certain TTL.
1064 * A plugin to monitor the hardware sensors of Apple computers has been
1066 * The plugins `cpu', `memory', `processes' and `traffic' have been
1067 ported to Mach/Darwin (Mac OS X).
1068 * The `log mode' has been contributed by Christophe Kalt. It writes
1069 the data into text files rather than RRD files.
1071 2006-04-09, Version 3.8.4
1072 * Applied patch by Vincent Stehlé which improves the disk-name
1073 resolution in the `hddtemp' plugin for Linux systems.
1075 2006-04-02, Version 3.8.3
1076 * Applied a patch by James Byers: The MySQL plugin was not working
1077 with MySQL 5.0.2 or later.
1079 2006-03-14, Version 3.8.2
1080 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1081 the GNU libc, because it points to `/etc/fstab' rather than
1084 2006-03-13, Version 3.8.1
1085 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1086 * Fixes in the debian `postinst' and `init.d' scripts.
1088 2006-03-09, Version 3.8.0
1089 * The `ping' plugin no longer uses `libping' but a self written
1090 library named `liboping'. With this library it's possible to ping
1091 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1093 2006-02-18, Version 3.7.2
1094 * A simple bug in the `battery' plugin has been fixed. It should now
1095 work with ACPI based batteries as well. Thanks to Sebastian for
1097 * Fixing a bug that prevented collectd to be built without librrd.
1098 Thanks to Werner Heuser for reporting it.
1100 2006-02-04, Version 3.7.1
1101 * The new network code has been improved to build with older versions

1104 to Tommie Gannert for this patch.
1106 2006-01-30, Version 3.7.0
1107 * The `battery' plugin has been added. It collects information about
1109 * The MySQL plugin has been improved: It now writes two more RRD
1110 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1111 * The `cpufreq' plugin now reads another file since the file it did
1112 read so far causes much overhead in the kernel. Also, you need root
1113 to read the old file, but not to read the new one.
1114 * The `hddtemp' plugin can now be configured to connect to another
1115 address and/or port than localhost.
1116 * The `df' plugin now prefers `statvfs' over `statfs'.
1117 * The network code has been rewritten. collectd now supports unicast
1118 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1119 be set in the configfile.
1121 2006-01-24, Version 3.6.2
1122 * Due to a bug in the configfile handling collectd wouldn't start in
1123 client mode. This released fixes this.
1125 2006-01-20, Version 3.6.1
1126 * Due to a bug in `configure.in' all modules and the binary were
1127 linked against `libmysqlclient'. This issue is solved by this
1130 2006-01-17, Version 3.6.0
1131 * A config file has been added. This allows for loading only specific
1133 * A `df' plugin has been added.
1134 * A `mysql' plugin has been added.
1135 * The `ping' plugin doesn't entirely give up hope when a socket error
1136 occurred, but will back of and increase the intervals between tries.
1138 2006-01-21, Version 3.5.2
1139 * Fixed yet another bug in the signal handling.. Stupid typo..
1140 * Improved the ping plugin to not give up on socket errors (backport
1143 2005-12-18, Version 3.5.1
1144 * The PID-file is now deleted correctly when shutting down the daemon.
1145 * SIGINT and SIGTERM are now handled correctly.
1147 2005-12-16, Version 3.5.0 (Revision 326)
1148 * A bug in the `load' module under Solaris has been fixed.
1149 * The `users' module has been contributed by Sebastian Harl. It counts
1150 currently logged in users.
1151 * The CPU module now works under FreeBSD without the use of
1152 `libstatgrab', however SMP support is missing.
1153 * The default directories for the RRD files and the PID file now
1154 depend on the compile time setting of `localstatedir'.
1156 2005-11-15, Version 3.4.0 (Revision 236)
1157 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1158 from gentoo's bugzilla for writing the patch.
1159 * The build dependency for librrd has been removed. Binaries built
1160 without librrd are client-only and will multicast their value as
1161 with the `-c' argument.
1162 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1163 * The newly introduced `-f' switch prevents daemon initialization
1164 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1165 Barcellos for this patch.
1167 2005-11-04, Version 3.3.0 (Revision 216)
1168 * New modules have been added:
1169 - `serial', for monitoring traffic on the serial interfaces
1170 - `nfs', for graphing NFS procedure calls
1171 - `tape', traffic from/to tape devices
1172 * The memory.rrd now accepts more than 4Gig of memory.
1174 2005-10-26, Version 3.2.0 (Revision 200)
1175 * Support for graphing the processes has been added (thanks to Lyonel
1177 * If reading from hddtemp fails collectd will increase the time
1178 between polls up to one day.
1179 * The init.d files have been improved.
1180 * Problems with the spec file have been fixed.
1182 2005-10-16, Version 3.1.0 (Revision 194)
1183 * Added the `setsid' syscall to the startup code.
1184 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1186 2005-09-30, Version 3.0.0 (Revision 184)
1187 * The ability to send/receive data to/from the network (think
1188 multicast) has been added.
1189 * Modules have been split up into shared libraries can be loaded at
1190 runtime. The biggest advantage is that the core program doesn't need
1191 to be linked against an external library.
1192 * A patch by George Kargiotakis has been applied: It fixes the sensors
1193 behaviour then more than one sensor is being queried.
1195 2005-09-16, Version 2.1.0 (Revision 172)
1196 * A module for swap statistics has been added.
1198 2005-09-09, Version 2.0.0 (Revision 135)
1199 * Filenames can no longer be configured at program startup. The only
1200 options as of this version are the directory and ping hosts.
1201 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1202 Soft-IRQ statistics are added to `System'.
1203 * Diskstats now collect read and write bytes, not sectors.
1204 * Ping statistics can now be collected for more than one host. There
1205 is no default any more: If no host is given no host will be pinged.
1206 * A self-written patch for libping has been applied so it builds
1209 2005-09-01, Version 1.8.1 (Revision 123)
1210 * Much improved configure-script: libraries and features may now be
1212 * More detailed warnings/error messages when RRD update fails.
1214 2005-08-29, Version 1.8.0:
1215 * Support for collecting disk statistics under Solaris.
1217 2005-08-25, Version 1.7.0:
1218 * Support for libstatgrab[1] for load, memory usage and network
1219 traffic. CPU- and disk-usage are not (yet) supported, since
1220 libstatgrab returns insufficient information. I will contact the
1222 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1223 aren't necessarily counted linear which is now handled correctly.
1224 [1]: http://www.i-scream.org/libstatgrab/
1226 2005-08-21, Version 1.6.0:
1227 * Basic support for Solaris: System load and cpu-usage can be
1228 collected under Solaris, too. Other stats will follow later.
1229 * Many fixes in the autoconf-script
1230 * Collection/Museum scripts have been added under contrib/museum
1231 * collectd may now be started in unprivileged mode, though ping
1232 statistics will not work.
1234 2005-07-17, Version 1.5.1:
1235 * Diskstats-RRDs now use major/minor for naming. Some systems have
1236 weird strings as disk-names..
1238 2005-07-17, Version 1.5:
1239 * A new module, diskstats, has been added. It collects information
1240 about the disks and partitions.
1242 2005-07-11, Version 1.4.2:
1243 * The meminfo module has been changed to work with more platforms
1244 and/or kernel versions.
1246 2005-07-10, Version 1.4.1: Correct traffic stats
1247 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1248 forgot to correct when I changed that module.
1250 2005-07-09, Version 1.4: More traffic stats
1251 * Traffic is now collected for all interfaces that can be found
1252 * Temperature-statistics are read from lm-sensors if available
1254 2005-07-08, Version 1.3: CPU stats
1255 * Collecting CPU statistics now
1257 2005-07-12, Version 1.2: Using syslog
1258 * collectd is now using the syslog facility to report errors, warnings
1260 * The default directory is now /var/db/collectd
1262 2005-07-10, Version 1.1: Minor changes
1263 * Nothing really useful to say ;)
1265 2005-07-09, Version 1.0: Initial Version
1266 * The following modules are provided:
