326 name which prevented this match to be used as documented. Thanks to
327 Bruno Prémont for finding this problem.
328 * bind plugin: Fix collection of the cached RR sets. The number of RR
329 sets currently in the cache was collected as a counter value, which
330 is nonsense. Thanks to Bruno Prémont for implementing this.
331 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
332 primarily BSDs, don't take it well and crash.
333 * oracle plugin: Portability to 64 bit systems has been improved.
334 * postgresql plugin: The default configuration has been improved.
335 * rrdtool plugin: Fix a possible race condition: If the network plugin

350 user to use `matches' and `targets' to control value processing.
351 * collectd: The new `-T' command line argument allows more in-depth
352 testing of a configuration. Thanks to Doug MacEachern for the patch.
353 * collectd-nagios: The Nagios integration command has been updated to

378 them using the same mechanism that's used in the tail plugin.
379 * dbi plugin: This new plugin allows you to connect to a variety of
380 relational databases and use SQL to gather custom statistics from
381 it. It is similar to the already existing PostgreSQL plugin but uses
382 libdbi to communicate with the database(s).
383 * interface plugin: Use the ignorelist framework when selecting /
384 ignoring interfaces. This allows one to use regular expressions to
385 select interfaces, too.
386 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
387 Thanks to Bruno Prémont for this patch.
388 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

410 * processes plugin: Stacksize and virtual memory usage statistics have
411 been added. Portability fixes.
412 * rrdcached plugin: This new plugin uses the (still in development)
413 RRD accelerator daemon, rrdcached. This daemon works very similar to
414 the original rrdtool plugin of collectd, but adds some more nice
416 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
419 2009-05-09, Version 4.5.4
420 * Build system, various plugins: Many build fixes for FreeBSD,

433 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
435 * rrdtool plugin: Fix a possible race condition: If the network plugin
436 is initialized and dispatches a value before the rrdtool plugin is
437 initialized, the daemon may crash.
438 * memory plugin: Fix a potential problem under Solaris.
440 2009-02-22, Version 4.5.3
441 * build system: The check for libupsclient even when `pkg-config' is
443 * collectd: Fix error handling in the global cache.
444 * Collectd::Unixsock: Error handling has been improved.
445 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
447 * ipmi plugin: Fix an off-by-one error which could cause segmentation
448 faults. Thanks to Peter Holik for his patch.

450 code. Thanks to "thated" for reporting this.
452 2009-01-02, Version 4.5.2
453 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
454 file may be in both locations, especially when the database was
455 installed in a non-standard path. Thanks to Dusty Doris for
457 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
458 Solaris, in the configure script automatically.
459 * build system, tcpconns plugin: Check for `kvm_nlist' and
460 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
461 library with similar functions to the BSD variant, but doesn't
462 provide these necessary functions.
463 * collectd.conf(5): Various fixes and clarifications.
464 * collectd: Remove a GNUism (unnamed unions), thus improving
466 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
467 This solves portability problems, especially for Solaris.
468 * dns plugin: Fix a portability problem with NetBSD.
469 * filecount plugin: Fix an off-by-one error. This error may cause a
471 * network plugin: Fix the handling of `type' in the network protocol.
472 Due to a programming mistake, only 4 or 8 bytes would be copied to a
473 much larger buffer. This caused the `type' to be transferred much
474 more often than necessary. In some cases, e. g. the `cpu' and
475 `cpufreq' plugins being used at the same time, data may be corrupted
476 in those files. Thanks to Bruno Prémont for debugging and reporting
478 * processes plugin: Fix a possible segmentation fault when specifying
479 invalid configuration options.
480 * unixsock plugin: Make sure the initialization function is run only
481 once. This resolves a file descriptor leak under systems which run
482 the initialization more than once, such as Solaris.
484 2008-10-16, Version 4.5.1
485 * build system: Change `--enable-<plugin>' to abort with an error if
486 dependencies are not met. Thanks to Bruno Prémont for the patch.
487 Also, the poisoning of various string functions has been restricted
489 * collectd: Fix a memory leak in the global value cache. With every
490 *missing* value a couple of bytes would be leaked. Another memory
491 leak in the configuration handling code has been fixed. Thanks to
492 Niraj Tolia for reporting these issues.
493 * collectd: Fix an off-by-one error in the ignorelist functionality.
494 When using regular expressions, the last character would be missing,
495 possibly matching differently from what one would expect.
496 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
498 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
499 Linzberger for reporting the bug.
500 * iptables plugin: Fix an off-by-one error. If a string was just one
501 character too long, it was truncated instead of reporting an error.
502 * network plugin: Fix a memory leak in the configuration handling
503 code. Thanks to Niraj Tolia for reporting this issue.
504 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
505 * postgresql plugin: Don't reopen connection during reinitialization.
506 This fixes a bug under Solaris and potentially other platforms.
507 Missing calls to `PQclear' have been added, too. This fixes memory
508 leaks. Thanks to ``Admin'' for reporting these bugs.
509 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
511 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
512 problems with some `libc's. Thanks to Matthias Lay for reporting the
515 2008-09-04, Version 4.5.0
516 * collectd: Added the ability to flush certain identifiers.
517 * collectd: The concept of `notification meta data' has been
519 * filecount plugin: The new filecount plugin counts the number of
520 files in a directory and its subdirectories.
521 * ipmi plugin: Sensor names have been changed to ensure unique names.
522 Notifications upon added and removed sensors can now be generated.
523 * notify_desktop plugin: This new plugin sends notifications to the
524 X desktop using the structure defined in the `Desktop Notification
526 * notify_email plugin: This new plugin sends out notifications via
527 email, using the `esmtp' library.
528 * onewire plugin: The new experimental(!) onewire plugin reads values,
529 such as temperatures, from sensors connected to the computer via the
531 * perl plugin: Improved synchronized access to internal data structures
532 and fixed a possible dead-lock.
533 * perl plugin: Added the ability to flush certain identifiers and marked
534 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
536 * perl plugin: Added the ability to configure Perl plugins.
537 * postgresql plugin: The new postgresql plugin collects statistics
538 about or from a PostgreSQL database.
539 * processes plugin: The `ProcessMatch' option has been added.
540 * rrdtool plugin: Implement throttling of the `update queue' to lessen
542 * tcpconns plugin: This plugin has been ported to OpenBSD.
543 * thermal plugin: The new thermal plugin collects system temperatures
544 using Linux ACPI thermal zone data.
546 2009-01-02, Version 4.4.5
547 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
548 file may be in both locations, especially when the database was
549 installed in a non-standard path. Thanks to Dusty Doris for
551 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
552 Solaris, in the configure script automatically.
553 * collectd.conf(5): Various fixes and clarifications.
554 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
555 portability problems, especially for Solaris.
556 * dns plugin: Fix a portability problem with NetBSD.
557 * network plugin: Fix the handling of `type' in the network protocol.
558 Due to a programming mistake, only 4 or 8 bytes would be copied to a
559 much larger buffer. This caused the `type' to be transferred much
560 more often than necessary. In some cases, e. g. the `cpu' and
561 `cpufreq' plugins being used at the same time, data may be corrupted
562 in those files. Thanks to Bruno Prémont for debugging and reporting
564 * unixsock plugin: Make sure the initialization function is run only
565 once. This resolves a file descriptor leak under systems which run
566 the initialization more than once, such as Solaris.
568 2008-10-16, Version 4.4.4
569 * build system: Change `--enable-<plugin>' to abort with an error if
570 dependencies are not met. Thanks to Bruno Prémont for the patch.
571 Also, the poisoning of various string functions has been restricted
573 * collectd: Fix a memory leak in the global value cache. With every
574 *missing* value a couple of bytes would be leaked. Another memory
575 leak in the configuration handling code has been fixed. Thanks to
576 Niraj Tolia for reporting these issues.
577 * collectd: Fix an off-by-one error in the ignorelist functionality.
578 When using regular expressions, the last character would be missing,
579 possibly matching differently from what one would expect.
580 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
582 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
583 Linzberger for reporting the bug.
584 * network plugin: Fix a memory leak in the configuration handling
585 code. Thanks to Niraj Tolia for reporting this issue.
586 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
587 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
588 problems with some `libc's. Thanks to Matthias Lay for reporting the
591 2008-09-01, Version 4.4.3
592 * collectd: Fix a memory leak in the threshold checking code.
593 * memcached plugin: Fix a too short timeout and a related file

598 2008-07-15, Version 4.4.2
599 * build system: Use pkg-config to detect the upsclient library.
600 * collectd: Try even harder to determine the endianess of the
601 architecture collectd is being built on.
602 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
604 * dns plugin: Fix compilation errors with BIND versions 19991001
606 * network plugin: Bugfix in the init routine: The init function
607 cleared a buffer regardless of its contents. This could lead to lost
608 values under Solaris.
609 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
610 * vserver plugin: Remove usage of the thread-unsafe `readdir'
612 * wireless plugin: Work around incorrect noise and power values
613 returned by some broken drivers.
615 2008-06-03, Version 4.4.1
616 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
617 to kyrone for reporting this.
618 * collectd: Fixed min/max output in notifications generated by
620 * collectd-nagios: Fix the protocol used to communicate with the
622 * perl plugin: Fail noisily, but don't shutdown the daemon, if
623 initialization has errors. An issue with Perl 5.10 has been fixed.
624 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
625 René Rebe and Siegmund Gorr for reporting this.
627 2008-05-06, Version 4.4.0
628 * collectd: Internal code cleanups.
629 * collectd: Added support for a `Flush' command in the unixsock and
630 exec plugins. This command can be used to force a plugin (or all) to
631 flush its values to disk.
632 * collectd: Thresholds can now be configured to apply to one data
633 source only, making it possible to configure different thresholds
634 for each data source.
635 * apache, nginx plugins: Added the possibility to disable host and/or
637 * ascent plugin: The new ascent plugin reads and parses the statistics
638 page of an Ascent server.
639 * cpu plugin: Support for the statgrab library has been added.
640 * disk plugin: The possibility to ignore certain disks or collect only
641 specific disks has been added.
642 * disk plugin: Support for the statgrab library has been added.
643 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
644 sensor values via IPMI, the intelligent platform management
646 * iptables plugin: The iptc library that is used by the iptables
647 plugin has been added to the distribution, because it is not
648 provided by all distributions and removed from at least one.
649 * powerdns plugin: The new powerdns plugin reads statistics from an
650 authoritative or a recursing PowerDNS name server.
651 * rrdtool plugin: The size of the files generated with the default
652 configuration has been decreased.
653 * tail plugin: The new tail plugin can be used to gather statistics by
654 continuously reading from log files.
655 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
656 TeamSpeak2 server and collects statistics about the number of users
657 and number of channels.
658 * users plugin: Support for the statgrab library has been added.
659 * vmem plugin: The new vmem plugin collects very detailed statistics
660 about the virtual memory subsystem of Linux.
662 2008-08-30, Version 4.3.4
663 * Build system: Improved detection of and linking with the statgrab
665 * collectd: Portability fixes, especially to determine endianess more
667 * Various plugins: Fix format strings.
668 * disk plugin: A fix for giving disks under Linux 2.4 the right names
669 again has been applied.
670 * memcached plugin: Fix a too short timeout and a related file
672 * memory plugin: A typo in the libstatgrab code has been fixed.
673 * network plugin: A fix in the initialization function solves problems

676 * vserver plugin: A thread-unsafe function has been replaced.
677 * wireless plugin: A work-around for broken wireless drivers has been
680 2008-04-22, Version 4.3.3
681 * build system: Improved detection of several libraries, especially if
682 they are in non-standard paths.
683 * build system: Portability fixes: Automatically define "_REENTRANT"
684 if the libc expects it.
685 * collectd: Error and warning messages have been improved.
686 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
688 * apache plugin: Allocate new memory when reading a webpage instead of
689 using a buffer of static size.
690 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
692 * hddtemp plugin: Error and warning messages have been improved.
693 * sensors plugin: Fix sensor collection for some chip types.
695 2008-03-29, Version 4.3.2
696 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
697 `Persist' threshold options.
698 * collectd: Fix handling of missing values in the global value cache.
699 * collectd: Improved error messages when parsing the configuration.

702 * wireless plugin: Fix reading noise value.
704 2008-03-05, Version 4.3.1
705 * exec plugin: Set supplementary group IDs.
707 + Use `memcpy' when constructing/parsing a package to avoid
708 alignment problems on weird architectures, such as Sparc.
709 + Translate doubles to/from the x86 byte representation to ensure
710 cross-platform compatibility.
711 * ping plugin: Correct the handling of the `TTL' setting.
712 * swap plugin: Reapply a patch for Solaris.
713 * tcpconns plugin: Portability improvements.
715 2008-02-18, Version 4.3.0
716 * collectd: Notifications have been added to the daemon. Notifications
717 are status messages that may be associated with a data instance.
718 * collectd: Threshold checking has been added to the daemon. This
719 means that you can configure threshold values for each data
720 instance. If this threshold is exceeded a notification will be
722 * collectd: The new `FQDNLookup' option tells the daemon to use the
723 full qualified domain name as the hostname, not just the host part
724 es returned by `gethostname(2)'.
725 * collectd: Support for more than one `TypesDB' file has been added.
726 This is useful when one such file is included in a package but one
727 wants to add custom type definitions.
728 * collectd: The `Include' config option has been expanded to handle
729 entire directories and shell wildcards.
730 * collectdmon: The new `collectdmon' binary detects when collectd
731 terminates and automatically restarts it again.
732 * csv plugin: The CSV plugin is now able to store counter values as a
733 rate, using the `StoreRates' configuration option.
734 * exec plugin: Handling of notifications has been added and the
735 ability to pass arguments to the executed programs has been added.
736 * hddtemp plugin: The new `TranslateDevicename' option lets you
737 disable the translation from device names to major-minor-numbers.
738 * logfile plugin: Handling of notifications has been added.
739 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
740 domain name lookups in this plugin.
741 * perl plugin: Many internal changes added support for handling multiple
742 threads making the plugin reasonably usable inside collectd. The API has
743 been extended to support notifications and export global variables to
744 Perl plugins; callbacks now have to be identified by name rather than a
745 pointer to a subroutine. The plugin is no longer experimental.
746 * uuid plugin: The new UUID plugin sets the hostname to an unique
747 identifier for this host. This is meant for setups where each client
748 may migrate to another physical host, possibly going through one or
749 more name changes in the process. Thanks to Richard Jones from
750 Red Hat's Emerging Technology group for this plugin.
751 * libvirt: The new libvirt plugin uses the `libvirt' library to query
752 CPU, disk and network statistics about guest systems on the same
753 physical server. Thanks to Richard Jones from Red Hat's Emerging
754 Technology group for this plugin.
756 2008-04-22, Version 4.2.7
757 * build system: Improved detection of several libraries, especially if
758 they are in non-standard paths.
759 * build system: Portability fixes: Automatically define "_REENTRANT"
760 if the libc expects it.
761 * collectd: Error and warning messages have been improved.
762 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
764 * apache plugin: Allocate new memory when reading a webpage instead of
765 using a buffer of static size.
766 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
768 * hddtemp plugin: Error and warning messages have been improved.
769 * sensors plugin: Fix sensor collection for some chip types.

773 * sensors plugin: Fix temperature collection with libsensors4.
774 * unixsock plugin: Fix mixed input and output operation on streams.
775 * wireless plugin: Fix reading noise value.
777 2008-03-04, Version 4.2.5
778 * apache plugin: Improved initialization and error messages.
779 * exec plugin: Set supplementary group IDs.
781 + Create separate threads for reading from the socket and parsing
782 and dispatching incoming packets. Versions prior to this may have
783 problems in high-load situations, where the socket receive buffers
784 overflows, resulting in gaps in the data.
785 + Use `memcpy' when constructing/parsing a package to avoid
786 alignment problems on weird architectures, such as Sparc.
787 + Translate doubles to/from the x86 byte representation to ensure
788 cross-platform compatibility.
789 * ping plugin: Correct the handling of the `TTL' setting.
790 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
791 * swap plugin: Reapply a patch for Solaris.
792 * tcpconns plugin: Portability improvements.
794 2008-01-21, Version 4.2.4
795 * unixsock plugin: A bug in the unixsock plugin caused it not to set
796 the permission on the socket as documented in the manpage. Thanks to
797 Evgeny Chukreev for fixing this issue.
798 * collectd: The documentation has been improved.
800 2007-12-28, Version 4.2.3
801 * sensors plugin: Updated the plugin to build and work with version 3
802 of the libsensors library.
804 2007-12-15, Version 4.2.2
805 * nginx plugin: Incorrect comparison of strings lead to a segfault
806 when using the plugin. Thanks to Saulius Grigaliunas for fixing
808 * logfile plugin: The config option `Timestamp' was handled
809 incorrectly and basically always active. Thanks to Luke Heberling
812 2007-11-08, Version 4.2.1
813 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
815 * snmp plugin: Fix a memory leak.
817 2007-10-27, Version 4.2.0
818 * collectd: The new config option `Include' lets you include other
819 configfiles and thus split up your config into smaller parts. This
820 may be especially interesting for the snmp plugin to keep the data
821 definitions separate from the host definitions.
822 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
823 (number of connections, octets and packets for each service and
824 destination). Thanks to Sebastian Harl for this plugin.
825 * memcached plugin: The new `memcached' plugin connects to a memcached
826 daemon process and collects statistics of this distributed caching
827 system. Thanks to Antony Dovgal for contributing this plugin.
828 * nginx plugin: The new `nginx' plugin reads the status page of an
829 nginx daemon and saves the handled connections and requests.
830 * perl plugin: Many changes, including the added `EnableDebugger'
831 config option which lets you debug your Perl plugins more easily.
832 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
833 be more thread-safe otherwise by locking calls to the library.
834 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
835 correct the values returned by SNMP-agents. If a <data> block is
836 defined as `table' the instance is now optional. The sequence number
837 is used as the type-instance in this case. The new `InstancePrefix'
838 option allows to add arbitrary prefixes to the type-instance.
839 * tcpconns plugin: The new `tcpconns' plugin collects the number of
840 certain TCP connections and what state they're in. This can be used
841 to see how many connections your FTP server has to handle or how
842 many outgoing connections your mailserver has open.
844 2008-01-11, Version 4.1.6
845 * unixsock plugin: A bug in the unixsock plugin caused it not to set
846 the permission on the socket as documented in the manpage. Thanks to
847 Evgeny Chukreev for fixing this issue.
848 * collectd: The documentation has been improved.
850 2007-12-27, Version 4.1.5

854 of the libsensors library.
856 2007-11-08, Version 4.1.4
857 * Build system: Improve detection of the rrd library, especially if
858 it's in a non-standard location.
859 * Build system: A bug when parsing the argument for
860 `--with-libnetsnmp' has been fixed.
861 * collectd: Implement `strerror_r' if the libc doesn't provide it.
862 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
863 a deadlock or delay when shutting down the daemon.
864 * snmp plugin: Fix a memory leak.
866 2007-10-24, Version 4.1.3
867 * collectd: A build issue under Solaris has been resolved by renaming
869 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
870 be more thread-safe otherwise by locking calls to the library.
872 2007-09-28, Version 4.1.2
873 * apcups plugin: Fix reporting of the `load percent' data.
874 * wireless plugin: Correct the handling of cards returning signal and
875 noise quality as percentage.
876 * perl plugin: Fix a possible buffer overflow in get_module_name().
877 * build system: Further improve the detection of libraries.
878 * netlink plugin: Build issues under some older versions of the Linux
879 includes (i. e. Debian Sarge) have been fixed.
880 * snmp plugin: Fix a potential segfault when a host times out. Add
881 support for the `timeticks' type.
883 2007-09-12, Version 4.1.1
884 * Build system: The detection of `libnetlink' has been improved.
885 * collectd: The documentation has been fixed in numerous places.
886 * exec plugin: Setting the group under which to run a program has been
888 * collectd: The `sstrerror' function was improved to work correctly
889 with the broken GNU version of `strerror_r'.
890 * collectd: Write an error message to STDERR when loading of a plugin
892 * apcups plugin: Fix the `types' used to submit the values: They still
893 has an `apcups_' prefix which doesn't work anymore.
894 * rrdtool plugin: Create new RRD-files with the `begin' time set to
895 whatever the client thinks is `now'..
897 2007-09-01, Version 4.1.0
898 * Build system: The build system has been changed to automatically
899 disable all plugins, which are missing dependencies. The dependency
900 checking has been removed from the plugins themselves to remove
902 * Flexible interval: The interval of collected data is now sent along
903 with the data itself over the network, so that the interval-settings
904 of server and clients no longer needs to match.
905 * netlink plugin: The new `netlink' plugin connects to the Linux
906 kernel using a netlink socket and uses it to query information about
907 interfaces, qdiscs and classes.
908 * rrdtool plugin: The cache is now dumped to disk in an extra thread
909 to not block data collection.
910 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
911 network devices, such as switches, routers, thermometers, rack
912 monitoring servers, etc. The collectd-snmp(5) manpage documents this
914 * unixsock plugin: Added the `LISTVAL' command.
915 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
916 of music played with xmms.
918 2007-09-28, Version 4.0.9
919 * apcups plugin: Fix reporting of the `load percent' data.
920 * wireless plugin: Correct the handling of cards returning signal and
921 noise quality as percentage.
922 * perl plugin: Fix a possible buffer overflow in get_module_name().
924 2007-09-12, Version 4.0.8
925 * collectd: The `sstrerror' function was improved to work correctly
926 with the broken GNU version of `strerror_r'.
927 * collectd: Write an error message to STDERR when loading of a plugin
929 * apcups plugin: Fix the `types' used to submit the values: They still
930 has an `apcups_' prefix which doesn't work anymore.
931 * rrdtool plugin: Create new RRD-files with the `begin' time set to
932 whatever the client thinks is `now'..
934 2007-08-26, Version 4.0.7
935 * documentation: Some typos have been fixed and some information has
937 * build system: Many fixes for detecting libraries in unusual places,
938 such as on RedHat systems. The affected libraries are `libcurl',
939 `libmysql', and `libupsclient'.
940 * network plugin: Allow the `Port' option to be specified as a number
941 (i. e. without quotes).
942 * nut plugin: A fix allows linking the nut plugin against
943 libupsclient, version >= 2.2.0.
944 * processes plugin: Fix a potential segmentation fault.
946 2007-07-30, Version 4.0.6
947 * sensors plugin: Fix the ignorelist functionality: Only the `type
948 instance' was used to match against the list, but the documentation
949 told otherwise. This release fixes the code, so it complies with the
951 * syslog plugin: Call `openlog' right when the plugin is loaded, so
952 configuration messages will end up in the logging facility.
953 * conrtib/fedora: The contributed specfile for Fedora has been
956 2007-07-05, Version 4.0.5
957 * Portability: More fixes for OpenBSD have been included.
959 2007-06-24, Version 4.0.4

965 * oconfig: Don't require `-lfl' anymore.
967 2007-06-19, Version 4.0.3
968 * cpu plugin: Fix the Darwin / Mac OS X code.
969 * ping plugin: Use the return value of `getpid', not its address.
970 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
971 initialized correctly.
972 * configure: Added `--with-nan-emulation' to aid cross compilation.
974 2007-06-12, Version 4.0.2
975 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
976 they're given in numerically form.
978 2007-06-07, Version 4.0.1
979 * iptables plugin: A bug in the configuration routine has been fixed.
980 Setting a comment in the configfile will no longer cause a
983 2007-06-03, Version 4.0.0
984 * collectd: The plugin-infrastructure has been changed to allow for
985 more types of plugins, namely `write' and `log' plugins.
986 * collectd: The read-function has been changed to read many plugins in
987 parallel, using threads. Thus, plugins generally need to use
988 thread-safe functions from now on.
989 * collectd: The '-t' command line options allows to perform syntax tests
990 of the configuration file and exit immediately.
991 * csv plugin: The new `csv' plugin handles output to `comma separated
993 * rrdtool plugin: The new `rrdtool' plugin handles output to
994 RRD-files. Data can be cached to combine multiple updates into one
995 write to increase IO-performance.
996 * network plugin: The new `network' plugin handles IO via the network.
997 It implements a different, much more extensible protocol which can
998 combine many values in one packet, decreasing the number of UDP-
999 packets being sent. It can read from and send to the network and
1000 with the appropriate configuration even forward packets to other
1002 * unixsock plugin: The new `unixsock' plugin provides an interface to
1003 communicate with the daemon while it is running. Right now the
1004 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1006 * perl plugin: The new `perl' plugin allows you to write extensions
1007 for collectd in the scripting-language Perl.
1008 * logfile plugin: The new `logfile' plugin writes logmessages to files
1009 or STDOUT or STDERR.
1010 * syslog plugin: The new `syslog' plugin sends logmessages to the
1011 system's syslog daemon.
1012 * entropy plugin: The new `entropy' plugin collects the amount of
1013 entropy currently being available to the system.
1014 * exec plugin: The new `exec' plugin forks child processes and reads
1015 back values provided by the forked processes.
1016 * iptables plugin: The new `iptables' plugin reads counters from
1017 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1019 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1020 to Peter Holik for contributing this plugin.
1021 * nut plugin: The new `nut' plugin connects the upsd of the `network
1022 ups tools' and reads information about the connected UPS.
1023 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1024 connections) field was added by Florent Monbillard.
1025 * collectd-nagios: The new `collectd-nagios' binary queries values
1026 from collectd, parses them and exits according to Nagios-standards.
1027 * manpages: The manpages have been improved a lot.
1029 2007-09-28, Version 3.11.7
1030 * wireless plugin: Correct the handling of cards returning signal and
1031 noise quality as percentage.
1033 2007-08-31, Version 3.11.6
1034 * processes plugin: Fix a potential segmentation fault.
1036 2007-05-29, Version 3.11.5
1037 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1038 * ntpd plugin: Fix a potential buffer overflow.
1039 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1040 were accounted as `zombies'.
1042 2007-04-10, Version 3.11.4
1043 * dns plugin: Change the order of includes to make the plugin compile
1046 2007-03-30, Version 3.11.3
1047 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1048 of the unused `COLLECT_KSTAT'.
1050 2007-02-11, Version 3.11.2
1051 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1052 NULL-pointer may have been passed to `printf' which causes a
1053 segfault with some libcs.
1055 2007-02-10, Version 3.11.1
1056 * df plugin: Some wrong defines have been fixed so the plugin works
1057 under Solaris again.
1058 * dns plugin: The usage of a struct has been fixed to work with
1060 * processes plugin: Some missing defines have been added so the plugin
1061 compiles cleanly under FreeBSD and presumably other UNIXes.
1063 2006-12-22, Version 3.11.0
1064 * collectd: The new command line option `-P' makes it easier for
1065 distributors to change the location of PID-files.
1066 * collectd: The daemon shuts down faster now which makes it easier to
1067 write init.d-scripts for it.
1068 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1069 caused problems every now and then.
1070 * df plugin: New config options allow to ignore certain mountpoints,
1071 filesystem types or devices.
1072 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1073 and interprets it. It collects traffic as well as qtype, opcode and
1075 * email plugin: Sebastian Harl has contributed this plugin which
1076 counts received mails in categories (e. g. ham, spam, virus), spam
1077 score (as given by SpamAssassin) and check types.
1078 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1079 uses `mbmon' to gather information from sensors on the motherboard.
1080 * processes plugin: Collect detailed statistics for configured
1081 processes, that's process and thread count, CPU usage, resident
1082 segment size and pagefaults.
1083 * multimeter plugin: Peter Holik contributed a new plugin which
1084 queries multimeters.
1085 * sensors plugin: Lubos Stanek has put much effort into improving this
1086 plugin, including `extended naming', collection of voltage values
1087 and the possibility to ignore certain values.
1089 2006-12-21, Version 3.10.4
1090 * Max Kellermann has identified a bug in the server routine: When
1091 opening a socket fails the daemon will (re)try opening the socket in
1092 an endless loop, ultimately leading to a `EMFILE' error.
1094 2006-11-04, Version 3.10.3
1095 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1096 ntpd's reply was sent in more than one packet, the buffer size was
1097 calculated incorrectly, resulting in the reading of uninitialized or
1100 2006-11-01, Version 3.10.2
1101 * The sample config file has been improved.
1102 * Errors in the manpages have been corrected.
1103 * The ping-plugin now adds hosts during initialization, not during
1104 startup. This speeds up startup when no network connectivity is
1105 available. Also, the hosts are being added later when the network is
1107 * Improved BSD-support for the df-plugin.
1108 * Fixed syntax errors in the swap-plugin for Mac OS X.
1109 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1111 * Don't disable the mysql-plugin if connecting to the database fails
1112 during initialization. Instead, try again in increasing intervals.
1114 2006-07-19, Version 3.10.1
1115 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1116 the apcups cannot be reached, unconnected sockets will pile up and
1117 eventually lead to `Too many open files' errors.
1119 2006-07-09, Version 3.10.0
1120 * The `disk' plugin has been ported to Darwin.
1121 * The `battery' plugin should work on many Apple computers now.
1122 * The `traffic' plugin can now ignore certain interfaces. Also,
1123 statistics for sent/received packets and errors have been added.
1124 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1125 to Anthony Gialluca for contributing this plugin and providing me
1126 with a test environment :)
1127 * A plugin for monitoring an NTP instance and the local clock drift
1130 2006-06-25, Version 3.9.4
1131 * The Solaris code in the `swap' plugin has been changed to reflect
1132 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1134 * The debugging system has been fixed to work with the Sun libc.
1135 * When built without librrd the variable `operating_mode' could be
1136 uninitialized. Thanks to David Elliot for reporting the bug.
1138 2006-06-01, Version 3.9.3
1139 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1140 operating systems also profit from the changes, but I wasn't able to
1142 * Changed the build system to find the netinet-includes under FreeBSD
1143 and therefore successfully build the `liboping' library there.
1145 2006-05-09, Version 3.9.2
1146 * Applied a patch to the `liboping' library. Due to a bug in the
1147 sequence checking the `ping' plugin stopped working after
1148 approximately 7.6 days.
1150 2006-05-09, Version 3.8.5
1151 * Applied a patch to the `liboping' library. Due to a bug in the
1152 sequence checking the `ping' plugin stopped working after
1153 approximately 7.6 days.
1155 2006-04-21, Version 3.9.1
1156 * Build issues with Solaris and possible other architectures have been
1158 * Problems when building the `apache'-plugin without `libcurl' have
1160 * A bug in the `ping' plugin has been fixed. Sorry folks.
1162 2006-04-02, Version 3.9.0
1163 * A plugin to monitor the Apache webserver has been added.
1164 <http://httpd.apache.org/>
1165 * A plugin to collect statistics about virtual servers using VServer.
1166 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1168 * A plugin for wireless LAN cards has been added. It monitors signal
1169 strength, link quality and noise ratio..
1170 * A plugin for Apple hardware sensors has been added.
1171 * An option to compile collectd with different `step' and `heartbeat'
1172 settings has been added. The size of RRAs is no longer static but
1173 calculated based on the settings for `step' and `width'.
1174 * The `ping' plugin can now be configured to use a certain TTL.
1175 * A plugin to monitor the hardware sensors of Apple computers has been
1177 * The plugins `cpu', `memory', `processes' and `traffic' have been
1178 ported to Mach/Darwin (Mac OS X).
1179 * The `log mode' has been contributed by Christophe Kalt. It writes
1180 the data into text files rather than RRD files.
1182 2006-04-09, Version 3.8.4
1183 * Applied patch by Vincent Stehlé which improves the disk-name
1184 resolution in the `hddtemp' plugin for Linux systems.
1186 2006-04-02, Version 3.8.3
1187 * Applied a patch by James Byers: The MySQL plugin was not working
1188 with MySQL 5.0.2 or later.
1190 2006-03-14, Version 3.8.2
1191 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1192 the GNU libc, because it points to `/etc/fstab' rather than
1195 2006-03-13, Version 3.8.1
1196 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1197 * Fixes in the debian `postinst' and `init.d' scripts.
1199 2006-03-09, Version 3.8.0
1200 * The `ping' plugin no longer uses `libping' but a self written
1201 library named `liboping'. With this library it's possible to ping
1202 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1204 2006-02-18, Version 3.7.2
1205 * A simple bug in the `battery' plugin has been fixed. It should now
1206 work with ACPI based batteries as well. Thanks to Sebastian for
1208 * Fixing a bug that prevented collectd to be built without librrd.
1209 Thanks to Werner Heuser for reporting it.
1211 2006-02-04, Version 3.7.1
1212 * The new network code has been improved to build with older versions
1214 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1215 to Tommie Gannert for this patch.
1217 2006-01-30, Version 3.7.0
1218 * The `battery' plugin has been added. It collects information about
1220 * The MySQL plugin has been improved: It now writes two more RRD
1221 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1222 * The `cpufreq' plugin now reads another file since the file it did
1223 read so far causes much overhead in the kernel. Also, you need root
1224 to read the old file, but not to read the new one.
1225 * The `hddtemp' plugin can now be configured to connect to another
1226 address and/or port than localhost.
1227 * The `df' plugin now prefers `statvfs' over `statfs'.
1228 * The network code has been rewritten. collectd now supports unicast
1229 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1230 be set in the configfile.
1232 2006-01-24, Version 3.6.2
1233 * Due to a bug in the configfile handling collectd wouldn't start in
1234 client mode. This released fixes this.
1236 2006-01-20, Version 3.6.1
1237 * Due to a bug in `configure.in' all modules and the binary were
1238 linked against `libmysqlclient'. This issue is solved by this
1241 2006-01-17, Version 3.6.0
1242 * A config file has been added. This allows for loading only specific
1244 * A `df' plugin has been added.
1245 * A `mysql' plugin has been added.
1246 * The `ping' plugin doesn't entirely give up hope when a socket error
1247 occurred, but will back of and increase the intervals between tries.
1249 2006-01-21, Version 3.5.2
1250 * Fixed yet another bug in the signal handling.. Stupid typo..
1251 * Improved the ping plugin to not give up on socket errors (backport
1254 2005-12-18, Version 3.5.1
1255 * The PID-file is now deleted correctly when shutting down the daemon.
1256 * SIGINT and SIGTERM are now handled correctly.
1258 2005-12-16, Version 3.5.0 (Revision 326)
1259 * A bug in the `load' module under Solaris has been fixed.
1260 * The `users' module has been contributed by Sebastian Harl. It counts
1261 currently logged in users.
1262 * The CPU module now works under FreeBSD without the use of
1263 `libstatgrab', however SMP support is missing.
1264 * The default directories for the RRD files and the PID file now
1265 depend on the compile time setting of `localstatedir'.
1267 2005-11-15, Version 3.4.0 (Revision 236)
1268 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1269 from gentoo's bugzilla for writing the patch.
1270 * The build dependency for librrd has been removed. Binaries built
1271 without librrd are client-only and will multicast their value as
1272 with the `-c' argument.
1273 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1274 * The newly introduced `-f' switch prevents daemon initialization
1275 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1276 Barcellos for this patch.
1278 2005-11-04, Version 3.3.0 (Revision 216)
1279 * New modules have been added:
1280 - `serial', for monitoring traffic on the serial interfaces
1281 - `nfs', for graphing NFS procedure calls
1282 - `tape', traffic from/to tape devices
1283 * The memory.rrd now accepts more than 4Gig of memory.
1285 2005-10-26, Version 3.2.0 (Revision 200)
1286 * Support for graphing the processes has been added (thanks to Lyonel
1288 * If reading from hddtemp fails collectd will increase the time
1289 between polls up to one day.
1290 * The init.d files have been improved.
1291 * Problems with the spec file have been fixed.
1293 2005-10-16, Version 3.1.0 (Revision 194)
1294 * Added the `setsid' syscall to the startup code.
1295 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1297 2005-09-30, Version 3.0.0 (Revision 184)
1298 * The ability to send/receive data to/from the network (think
1299 multicast) has been added.
1300 * Modules have been split up into shared libraries can be loaded at
1301 runtime. The biggest advantage is that the core program doesn't need
1302 to be linked against an external library.
1303 * A patch by George Kargiotakis has been applied: It fixes the sensors
1304 behaviour then more than one sensor is being queried.
1306 2005-09-16, Version 2.1.0 (Revision 172)
1307 * A module for swap statistics has been added.
1309 2005-09-09, Version 2.0.0 (Revision 135)
1310 * Filenames can no longer be configured at program startup. The only
1311 options as of this version are the directory and ping hosts.
1312 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1313 Soft-IRQ statistics are added to `System'.
1314 * Diskstats now collect read and write bytes, not sectors.
1315 * Ping statistics can now be collected for more than one host. There
1316 is no default any more: If no host is given no host will be pinged.
1317 * A self-written patch for libping has been applied so it builds
1320 2005-09-01, Version 1.8.1 (Revision 123)
1321 * Much improved configure-script: libraries and features may now be
1323 * More detailed warnings/error messages when RRD update fails.
1325 2005-08-29, Version 1.8.0:
1326 * Support for collecting disk statistics under Solaris.
1328 2005-08-25, Version 1.7.0:
1329 * Support for libstatgrab[1] for load, memory usage and network
1330 traffic. CPU- and disk-usage are not (yet) supported, since
1331 libstatgrab returns insufficient information. I will contact the
1333 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1334 aren't necessarily counted linear which is now handled correctly.
1335 [1]: http://www.i-scream.org/libstatgrab/
1337 2005-08-21, Version 1.6.0:
1338 * Basic support for Solaris: System load and cpu-usage can be
1339 collected under Solaris, too. Other stats will follow later.
1340 * Many fixes in the autoconf-script
1341 * Collection/Museum scripts have been added under contrib/museum
1342 * collectd may now be started in unprivileged mode, though ping
1343 statistics will not work.
1345 2005-07-17, Version 1.5.1:
1346 * Diskstats-RRDs now use major/minor for naming. Some systems have
1347 weird strings as disk-names..
1349 2005-07-17, Version 1.5:
1350 * A new module, diskstats, has been added. It collects information
1351 about the disks and partitions.
1353 2005-07-11, Version 1.4.2:
1354 * The meminfo module has been changed to work with more platforms
1355 and/or kernel versions.
1357 2005-07-10, Version 1.4.1: Correct traffic stats
1358 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1359 forgot to correct when I changed that module.
1361 2005-07-09, Version 1.4: More traffic stats
1362 * Traffic is now collected for all interfaces that can be found
1363 * Temperature-statistics are read from lm-sensors if available
1365 2005-07-08, Version 1.3: CPU stats
1366 * Collecting CPU statistics now
1368 2005-07-12, Version 1.2: Using syslog
1369 * collectd is now using the syslog facility to report errors, warnings
1371 * The default directory is now /var/db/collectd
1373 2005-07-10, Version 1.1: Minor changes
1374 * Nothing really useful to say ;)
1376 2005-07-09, Version 1.0: Initial Version
1377 * The following modules are provided:
