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

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

419 been added. Portability fixes.
420 * rrdcached plugin: This new plugin uses the (still in development)
421 RRD accelerator daemon, rrdcached. This daemon works very similar to
422 the original rrdtool plugin of collectd, but adds some more nice
424 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
427 2009-05-09, Version 4.5.4
428 * Build system, various plugins: Many build fixes for FreeBSD,

443 * rrdtool plugin: Fix a possible race condition: If the network plugin
444 is initialized and dispatches a value before the rrdtool plugin is
445 initialized, the daemon may crash.
446 * memory plugin: Fix a potential problem under Solaris.
448 2009-02-22, Version 4.5.3
449 * build system: The check for libupsclient even when `pkg-config' is

458 code. Thanks to "thated" for reporting this.
460 2009-01-02, Version 4.5.2
461 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
462 file may be in both locations, especially when the database was
463 installed in a non-standard path. Thanks to Dusty Doris for
465 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
466 Solaris, in the configure script automatically.
467 * build system, tcpconns plugin: Check for `kvm_nlist' and
468 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
469 library with similar functions to the BSD variant, but doesn't
470 provide these necessary functions.
471 * collectd.conf(5): Various fixes and clarifications.
472 * collectd: Remove a GNUism (unnamed unions), thus improving
474 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

477 * filecount plugin: Fix an off-by-one error. This error may cause a
479 * network plugin: Fix the handling of `type' in the network protocol.
480 Due to a programming mistake, only 4 or 8 bytes would be copied to a
481 much larger buffer. This caused the `type' to be transferred much
482 more often than necessary. In some cases, e. g. the `cpu' and
483 `cpufreq' plugins being used at the same time, data may be corrupted
484 in those files. Thanks to Bruno Prémont for debugging and reporting
486 * processes plugin: Fix a possible segmentation fault when specifying
487 invalid configuration options.
488 * unixsock plugin: Make sure the initialization function is run only
489 once. This resolves a file descriptor leak under systems which run
490 the initialization more than once, such as Solaris.
492 2008-10-16, Version 4.5.1
493 * build system: Change `--enable-<plugin>' to abort with an error if
494 dependencies are not met. Thanks to Bruno Prémont for the patch.
495 Also, the poisoning of various string functions has been restricted
497 * collectd: Fix a memory leak in the global value cache. With every
498 *missing* value a couple of bytes would be leaked. Another memory
499 leak in the configuration handling code has been fixed. Thanks to
500 Niraj Tolia for reporting these issues.
501 * collectd: Fix an off-by-one error in the ignorelist functionality.
502 When using regular expressions, the last character would be missing,
503 possibly matching differently from what one would expect.
504 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
506 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
507 Linzberger for reporting the bug.
508 * iptables plugin: Fix an off-by-one error. If a string was just one
509 character too long, it was truncated instead of reporting an error.
510 * network plugin: Fix a memory leak in the configuration handling
511 code. Thanks to Niraj Tolia for reporting this issue.
512 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
513 * postgresql plugin: Don't reopen connection during reinitialization.
514 This fixes a bug under Solaris and potentially other platforms.
515 Missing calls to `PQclear' have been added, too. This fixes memory
516 leaks. Thanks to ``Admin'' for reporting these bugs.
517 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
519 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
520 problems with some `libc's. Thanks to Matthias Lay for reporting the
523 2008-09-04, Version 4.5.0
524 * collectd: Added the ability to flush certain identifiers.
525 * collectd: The concept of `notification meta data' has been
527 * filecount plugin: The new filecount plugin counts the number of
528 files in a directory and its subdirectories.
529 * ipmi plugin: Sensor names have been changed to ensure unique names.
530 Notifications upon added and removed sensors can now be generated.
531 * notify_desktop plugin: This new plugin sends notifications to the
532 X desktop using the structure defined in the `Desktop Notification
534 * notify_email plugin: This new plugin sends out notifications via
535 email, using the `esmtp' library.
536 * onewire plugin: The new experimental(!) onewire plugin reads values,
537 such as temperatures, from sensors connected to the computer via the
539 * perl plugin: Improved synchronized access to internal data structures
540 and fixed a possible dead-lock.
541 * perl plugin: Added the ability to flush certain identifiers and marked
542 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
544 * perl plugin: Added the ability to configure Perl plugins.
545 * postgresql plugin: The new postgresql plugin collects statistics
546 about or from a PostgreSQL database.
547 * processes plugin: The `ProcessMatch' option has been added.
548 * rrdtool plugin: Implement throttling of the `update queue' to lessen
550 * tcpconns plugin: This plugin has been ported to OpenBSD.
551 * thermal plugin: The new thermal plugin collects system temperatures
552 using Linux ACPI thermal zone data.
554 2009-01-02, Version 4.4.5
555 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
556 file may be in both locations, especially when the database was
557 installed in a non-standard path. Thanks to Dusty Doris for
559 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
560 Solaris, in the configure script automatically.
561 * collectd.conf(5): Various fixes and clarifications.
562 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
563 portability problems, especially for Solaris.
564 * dns plugin: Fix a portability problem with NetBSD.
565 * network plugin: Fix the handling of `type' in the network protocol.
566 Due to a programming mistake, only 4 or 8 bytes would be copied to a
567 much larger buffer. This caused the `type' to be transferred much
568 more often than necessary. In some cases, e. g. the `cpu' and
569 `cpufreq' plugins being used at the same time, data may be corrupted
570 in those files. Thanks to Bruno Prémont for debugging and reporting
572 * unixsock plugin: Make sure the initialization function is run only
573 once. This resolves a file descriptor leak under systems which run
574 the initialization more than once, such as Solaris.
576 2008-10-16, Version 4.4.4
577 * build system: Change `--enable-<plugin>' to abort with an error if
578 dependencies are not met. Thanks to Bruno Prémont for the patch.
579 Also, the poisoning of various string functions has been restricted
581 * collectd: Fix a memory leak in the global value cache. With every
582 *missing* value a couple of bytes would be leaked. Another memory
583 leak in the configuration handling code has been fixed. Thanks to
584 Niraj Tolia for reporting these issues.
585 * collectd: Fix an off-by-one error in the ignorelist functionality.
586 When using regular expressions, the last character would be missing,
587 possibly matching differently from what one would expect.
588 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
590 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
591 Linzberger for reporting the bug.
592 * network plugin: Fix a memory leak in the configuration handling
593 code. Thanks to Niraj Tolia for reporting this issue.
594 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
595 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
596 problems with some `libc's. Thanks to Matthias Lay for reporting the
599 2008-09-01, Version 4.4.3
600 * collectd: Fix a memory leak in the threshold checking code.
601 * memcached plugin: Fix a too short timeout and a related file
603 * memory plugin: A typo in the libstatgrab code has been fixed.
604 * snmp plugin: Fix a possible memory leak.
606 2008-07-15, Version 4.4.2
607 * build system: Use pkg-config to detect the upsclient library.
608 * collectd: Try even harder to determine the endianess of the
609 architecture collectd is being built on.
610 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
612 * dns plugin: Fix compilation errors with BIND versions 19991001
614 * network plugin: Bugfix in the init routine: The init function
615 cleared a buffer regardless of its contents. This could lead to lost
616 values under Solaris.
617 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
618 * vserver plugin: Remove usage of the thread-unsafe `readdir'
620 * wireless plugin: Work around incorrect noise and power values
621 returned by some broken drivers.
623 2008-06-03, Version 4.4.1
624 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
625 to kyrone for reporting this.
626 * collectd: Fixed min/max output in notifications generated by
628 * collectd-nagios: Fix the protocol used to communicate with the
630 * perl plugin: Fail noisily, but don't shutdown the daemon, if
631 initialization has errors. An issue with Perl 5.10 has been fixed.
632 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
633 René Rebe and Siegmund Gorr for reporting this.
635 2008-05-06, Version 4.4.0
636 * collectd: Internal code cleanups.
637 * collectd: Added support for a `Flush' command in the unixsock and
638 exec plugins. This command can be used to force a plugin (or all) to
639 flush its values to disk.
640 * collectd: Thresholds can now be configured to apply to one data
641 source only, making it possible to configure different thresholds
642 for each data source.
643 * apache, nginx plugins: Added the possibility to disable host and/or
645 * ascent plugin: The new ascent plugin reads and parses the statistics
646 page of an Ascent server.
647 * cpu plugin: Support for the statgrab library has been added.
648 * disk plugin: The possibility to ignore certain disks or collect only
649 specific disks has been added.
650 * disk plugin: Support for the statgrab library has been added.
651 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
652 sensor values via IPMI, the intelligent platform management
654 * iptables plugin: The iptc library that is used by the iptables
655 plugin has been added to the distribution, because it is not
656 provided by all distributions and removed from at least one.
657 * powerdns plugin: The new powerdns plugin reads statistics from an
658 authoritative or a recursing PowerDNS name server.
659 * rrdtool plugin: The size of the files generated with the default
660 configuration has been decreased.
661 * tail plugin: The new tail plugin can be used to gather statistics by
662 continuously reading from log files.
663 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
664 TeamSpeak2 server and collects statistics about the number of users
665 and number of channels.
666 * users plugin: Support for the statgrab library has been added.
667 * vmem plugin: The new vmem plugin collects very detailed statistics
668 about the virtual memory subsystem of Linux.
670 2008-08-30, Version 4.3.4
671 * Build system: Improved detection of and linking with the statgrab
673 * collectd: Portability fixes, especially to determine endianess more
675 * Various plugins: Fix format strings.
676 * disk plugin: A fix for giving disks under Linux 2.4 the right names
677 again has been applied.
678 * memcached plugin: Fix a too short timeout and a related file
680 * memory plugin: A typo in the libstatgrab code has been fixed.
681 * network plugin: A fix in the initialization function solves problems
683 * nginx plugin: A thread-unsafe function has been replaced.
684 * vserver plugin: A thread-unsafe function has been replaced.
685 * wireless plugin: A work-around for broken wireless drivers has been
688 2008-04-22, Version 4.3.3
689 * build system: Improved detection of several libraries, especially if
690 they are in non-standard paths.
691 * build system: Portability fixes: Automatically define "_REENTRANT"
692 if the libc expects it.
693 * collectd: Error and warning messages have been improved.
694 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
696 * apache plugin: Allocate new memory when reading a webpage instead of
697 using a buffer of static size.
698 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
700 * hddtemp plugin: Error and warning messages have been improved.
701 * sensors plugin: Fix sensor collection for some chip types.
703 2008-03-29, Version 4.3.2
704 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
705 `Persist' threshold options.
706 * collectd: Fix handling of missing values in the global value cache.
707 * collectd: Improved error messages when parsing the configuration.

712 2008-03-05, Version 4.3.1
713 * exec plugin: Set supplementary group IDs.
715 + Use `memcpy' when constructing/parsing a package to avoid
716 alignment problems on weird architectures, such as Sparc.
717 + Translate doubles to/from the x86 byte representation to ensure
718 cross-platform compatibility.
719 * ping plugin: Correct the handling of the `TTL' setting.
720 * swap plugin: Reapply a patch for Solaris.
721 * tcpconns plugin: Portability improvements.
723 2008-02-18, Version 4.3.0
724 * collectd: Notifications have been added to the daemon. Notifications
725 are status messages that may be associated with a data instance.
726 * collectd: Threshold checking has been added to the daemon. This
727 means that you can configure threshold values for each data
728 instance. If this threshold is exceeded a notification will be
730 * collectd: The new `FQDNLookup' option tells the daemon to use the
731 full qualified domain name as the hostname, not just the host part
732 es returned by `gethostname(2)'.
733 * collectd: Support for more than one `TypesDB' file has been added.
734 This is useful when one such file is included in a package but one
735 wants to add custom type definitions.
736 * collectd: The `Include' config option has been expanded to handle
737 entire directories and shell wildcards.
738 * collectdmon: The new `collectdmon' binary detects when collectd
739 terminates and automatically restarts it again.
740 * csv plugin: The CSV plugin is now able to store counter values as a
741 rate, using the `StoreRates' configuration option.
742 * exec plugin: Handling of notifications has been added and the
743 ability to pass arguments to the executed programs has been added.
744 * hddtemp plugin: The new `TranslateDevicename' option lets you
745 disable the translation from device names to major-minor-numbers.
746 * logfile plugin: Handling of notifications has been added.
747 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
748 domain name lookups in this plugin.
749 * perl plugin: Many internal changes added support for handling multiple
750 threads making the plugin reasonably usable inside collectd. The API has
751 been extended to support notifications and export global variables to
752 Perl plugins; callbacks now have to be identified by name rather than a
753 pointer to a subroutine. The plugin is no longer experimental.
754 * uuid plugin: The new UUID plugin sets the hostname to an unique
755 identifier for this host. This is meant for setups where each client
756 may migrate to another physical host, possibly going through one or
757 more name changes in the process. Thanks to Richard Jones from
758 Red Hat's Emerging Technology group for this plugin.
759 * libvirt: The new libvirt plugin uses the `libvirt' library to query
760 CPU, disk and network statistics about guest systems on the same
761 physical server. Thanks to Richard Jones from Red Hat's Emerging
762 Technology group for this plugin.
764 2008-04-22, Version 4.2.7
765 * build system: Improved detection of several libraries, especially if
766 they are in non-standard paths.
767 * build system: Portability fixes: Automatically define "_REENTRANT"
768 if the libc expects it.
769 * collectd: Error and warning messages have been improved.
770 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
772 * apache plugin: Allocate new memory when reading a webpage instead of
773 using a buffer of static size.
774 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
776 * hddtemp plugin: Error and warning messages have been improved.
777 * sensors plugin: Fix sensor collection for some chip types.
779 2008-03-29, Version 4.2.6
780 * collectd: Improved error messages when parsing the configuration.
781 * sensors plugin: Fix temperature collection with libsensors4.
782 * unixsock plugin: Fix mixed input and output operation on streams.
783 * wireless plugin: Fix reading noise value.
785 2008-03-04, Version 4.2.5
786 * apache plugin: Improved initialization and error messages.
787 * exec plugin: Set supplementary group IDs.
789 + Create separate threads for reading from the socket and parsing
790 and dispatching incoming packets. Versions prior to this may have
791 problems in high-load situations, where the socket receive buffers
792 overflows, resulting in gaps in the data.
793 + Use `memcpy' when constructing/parsing a package to avoid
794 alignment problems on weird architectures, such as Sparc.
795 + Translate doubles to/from the x86 byte representation to ensure
796 cross-platform compatibility.
797 * ping plugin: Correct the handling of the `TTL' setting.
798 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
799 * swap plugin: Reapply a patch for Solaris.
800 * tcpconns plugin: Portability improvements.
802 2008-01-21, Version 4.2.4
803 * unixsock plugin: A bug in the unixsock plugin caused it not to set
804 the permission on the socket as documented in the manpage. Thanks to
805 Evgeny Chukreev for fixing this issue.
806 * collectd: The documentation has been improved.
808 2007-12-28, Version 4.2.3
809 * sensors plugin: Updated the plugin to build and work with version 3
810 of the libsensors library.
812 2007-12-15, Version 4.2.2
813 * nginx plugin: Incorrect comparison of strings lead to a segfault
814 when using the plugin. Thanks to Saulius Grigaliunas for fixing
816 * logfile plugin: The config option `Timestamp' was handled
817 incorrectly and basically always active. Thanks to Luke Heberling
820 2007-11-08, Version 4.2.1
821 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
823 * snmp plugin: Fix a memory leak.
825 2007-10-27, Version 4.2.0
826 * collectd: The new config option `Include' lets you include other
827 configfiles and thus split up your config into smaller parts. This
828 may be especially interesting for the snmp plugin to keep the data
829 definitions separate from the host definitions.
830 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
831 (number of connections, octets and packets for each service and
832 destination). Thanks to Sebastian Harl for this plugin.
833 * memcached plugin: The new `memcached' plugin connects to a memcached
834 daemon process and collects statistics of this distributed caching
835 system. Thanks to Antony Dovgal for contributing this plugin.
836 * nginx plugin: The new `nginx' plugin reads the status page of an
837 nginx daemon and saves the handled connections and requests.
838 * perl plugin: Many changes, including the added `EnableDebugger'
839 config option which lets you debug your Perl plugins more easily.
840 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
841 be more thread-safe otherwise by locking calls to the library.
842 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
843 correct the values returned by SNMP-agents. If a <data> block is
844 defined as `table' the instance is now optional. The sequence number
845 is used as the type-instance in this case. The new `InstancePrefix'
846 option allows to add arbitrary prefixes to the type-instance.
847 * tcpconns plugin: The new `tcpconns' plugin collects the number of
848 certain TCP connections and what state they're in. This can be used
849 to see how many connections your FTP server has to handle or how
850 many outgoing connections your mailserver has open.
852 2008-01-11, Version 4.1.6
853 * unixsock plugin: A bug in the unixsock plugin caused it not to set
854 the permission on the socket as documented in the manpage. Thanks to
855 Evgeny Chukreev for fixing this issue.

862 of the libsensors library.
864 2007-11-08, Version 4.1.4
865 * Build system: Improve detection of the rrd library, especially if
866 it's in a non-standard location.
867 * Build system: A bug when parsing the argument for
868 `--with-libnetsnmp' has been fixed.
869 * collectd: Implement `strerror_r' if the libc doesn't provide it.
870 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
871 a deadlock or delay when shutting down the daemon.
872 * snmp plugin: Fix a memory leak.
874 2007-10-24, Version 4.1.3
875 * collectd: A build issue under Solaris has been resolved by renaming
877 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
878 be more thread-safe otherwise by locking calls to the library.
880 2007-09-28, Version 4.1.2
881 * apcups plugin: Fix reporting of the `load percent' data.
882 * wireless plugin: Correct the handling of cards returning signal and
883 noise quality as percentage.
884 * perl plugin: Fix a possible buffer overflow in get_module_name().
885 * build system: Further improve the detection of libraries.
886 * netlink plugin: Build issues under some older versions of the Linux
887 includes (i. e. Debian Sarge) have been fixed.
888 * snmp plugin: Fix a potential segfault when a host times out. Add
889 support for the `timeticks' type.
891 2007-09-12, Version 4.1.1
892 * Build system: The detection of `libnetlink' has been improved.
893 * collectd: The documentation has been fixed in numerous places.
894 * exec plugin: Setting the group under which to run a program has been
896 * collectd: The `sstrerror' function was improved to work correctly
897 with the broken GNU version of `strerror_r'.
898 * collectd: Write an error message to STDERR when loading of a plugin
900 * apcups plugin: Fix the `types' used to submit the values: They still
901 has an `apcups_' prefix which doesn't work anymore.
902 * rrdtool plugin: Create new RRD-files with the `begin' time set to
903 whatever the client thinks is `now'..
905 2007-09-01, Version 4.1.0
906 * Build system: The build system has been changed to automatically
907 disable all plugins, which are missing dependencies. The dependency
908 checking has been removed from the plugins themselves to remove
910 * Flexible interval: The interval of collected data is now sent along
911 with the data itself over the network, so that the interval-settings
912 of server and clients no longer needs to match.
913 * netlink plugin: The new `netlink' plugin connects to the Linux
914 kernel using a netlink socket and uses it to query information about
915 interfaces, qdiscs and classes.
916 * rrdtool plugin: The cache is now dumped to disk in an extra thread
917 to not block data collection.
918 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
919 network devices, such as switches, routers, thermometers, rack
920 monitoring servers, etc. The collectd-snmp(5) manpage documents this
922 * unixsock plugin: Added the `LISTVAL' command.
923 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
924 of music played with xmms.
926 2007-09-28, Version 4.0.9
927 * apcups plugin: Fix reporting of the `load percent' data.
928 * wireless plugin: Correct the handling of cards returning signal and
929 noise quality as percentage.
930 * perl plugin: Fix a possible buffer overflow in get_module_name().
932 2007-09-12, Version 4.0.8
933 * collectd: The `sstrerror' function was improved to work correctly
934 with the broken GNU version of `strerror_r'.
935 * collectd: Write an error message to STDERR when loading of a plugin
937 * apcups plugin: Fix the `types' used to submit the values: They still
938 has an `apcups_' prefix which doesn't work anymore.
939 * rrdtool plugin: Create new RRD-files with the `begin' time set to
940 whatever the client thinks is `now'..
942 2007-08-26, Version 4.0.7
943 * documentation: Some typos have been fixed and some information has
945 * build system: Many fixes for detecting libraries in unusual places,
946 such as on RedHat systems. The affected libraries are `libcurl',
947 `libmysql', and `libupsclient'.
948 * network plugin: Allow the `Port' option to be specified as a number
949 (i. e. without quotes).
950 * nut plugin: A fix allows linking the nut plugin against
951 libupsclient, version >= 2.2.0.
952 * processes plugin: Fix a potential segmentation fault.
954 2007-07-30, Version 4.0.6
955 * sensors plugin: Fix the ignorelist functionality: Only the `type
956 instance' was used to match against the list, but the documentation
957 told otherwise. This release fixes the code, so it complies with the
959 * syslog plugin: Call `openlog' right when the plugin is loaded, so
960 configuration messages will end up in the logging facility.
961 * conrtib/fedora: The contributed specfile for Fedora has been
964 2007-07-05, Version 4.0.5
965 * Portability: More fixes for OpenBSD have been included.
967 2007-06-24, Version 4.0.4
968 * cpu plugin: Fixed the Solaris code.
969 * dns plugin: Fixed a build issue for OpenBSD.
970 * interface plugin: Fixed the Solaris code.
971 * load plugin: Fixed the alternative `/proc' Linux code.
972 * memory plugin: Fixed the Solaris code.
973 * oconfig: Don't require `-lfl' anymore.
975 2007-06-19, Version 4.0.3
976 * cpu plugin: Fix the Darwin / Mac OS X code.
977 * ping plugin: Use the return value of `getpid', not its address.
978 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
979 initialized correctly.
980 * configure: Added `--with-nan-emulation' to aid cross compilation.
982 2007-06-12, Version 4.0.2
983 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
984 they're given in numerically form.
986 2007-06-07, Version 4.0.1
987 * iptables plugin: A bug in the configuration routine has been fixed.
988 Setting a comment in the configfile will no longer cause a
991 2007-06-03, Version 4.0.0
992 * collectd: The plugin-infrastructure has been changed to allow for
993 more types of plugins, namely `write' and `log' plugins.
994 * collectd: The read-function has been changed to read many plugins in
995 parallel, using threads. Thus, plugins generally need to use
996 thread-safe functions from now on.
997 * collectd: The '-t' command line options allows to perform syntax tests
998 of the configuration file and exit immediately.
999 * csv plugin: The new `csv' plugin handles output to `comma separated
1001 * rrdtool plugin: The new `rrdtool' plugin handles output to
1002 RRD-files. Data can be cached to combine multiple updates into one
1003 write to increase IO-performance.
1004 * network plugin: The new `network' plugin handles IO via the network.
1005 It implements a different, much more extensible protocol which can
1006 combine many values in one packet, decreasing the number of UDP-
1007 packets being sent. It can read from and send to the network and
1008 with the appropriate configuration even forward packets to other
1010 * unixsock plugin: The new `unixsock' plugin provides an interface to
1011 communicate with the daemon while it is running. Right now the
1012 commands `GETVAL' and `PUTVAL' are implemented, but more are to
1014 * perl plugin: The new `perl' plugin allows you to write extensions
1015 for collectd in the scripting-language Perl.
1016 * logfile plugin: The new `logfile' plugin writes logmessages to files
1017 or STDOUT or STDERR.
1018 * syslog plugin: The new `syslog' plugin sends logmessages to the
1019 system's syslog daemon.
1020 * entropy plugin: The new `entropy' plugin collects the amount of
1021 entropy currently being available to the system.
1022 * exec plugin: The new `exec' plugin forks child processes and reads
1023 back values provided by the forked processes.
1024 * iptables plugin: The new `iptables' plugin reads counters from
1025 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1027 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1028 to Peter Holik for contributing this plugin.
1029 * nut plugin: The new `nut' plugin connects the upsd of the `network
1030 ups tools' and reads information about the connected UPS.
1031 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1032 connections) field was added by Florent Monbillard.
1033 * collectd-nagios: The new `collectd-nagios' binary queries values
1034 from collectd, parses them and exits according to Nagios-standards.
1035 * manpages: The manpages have been improved a lot.
1037 2007-09-28, Version 3.11.7
1038 * wireless plugin: Correct the handling of cards returning signal and
1039 noise quality as percentage.
1041 2007-08-31, Version 3.11.6
1042 * processes plugin: Fix a potential segmentation fault.
1044 2007-05-29, Version 3.11.5
1045 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1046 * ntpd plugin: Fix a potential buffer overflow.
1047 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1048 were accounted as `zombies'.
1050 2007-04-10, Version 3.11.4
1051 * dns plugin: Change the order of includes to make the plugin compile
1054 2007-03-30, Version 3.11.3
1055 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1056 of the unused `COLLECT_KSTAT'.
1058 2007-02-11, Version 3.11.2
1059 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1060 NULL-pointer may have been passed to `printf' which causes a
1061 segfault with some libcs.
1063 2007-02-10, Version 3.11.1
1064 * df plugin: Some wrong defines have been fixed so the plugin works
1065 under Solaris again.
1066 * dns plugin: The usage of a struct has been fixed to work with
1068 * processes plugin: Some missing defines have been added so the plugin
1069 compiles cleanly under FreeBSD and presumably other UNIXes.
1071 2006-12-22, Version 3.11.0
1072 * collectd: The new command line option `-P' makes it easier for
1073 distributors to change the location of PID-files.
1074 * collectd: The daemon shuts down faster now which makes it easier to
1075 write init.d-scripts for it.
1076 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1077 caused problems every now and then.
1078 * df plugin: New config options allow to ignore certain mountpoints,
1079 filesystem types or devices.
1080 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1081 and interprets it. It collects traffic as well as qtype, opcode and
1083 * email plugin: Sebastian Harl has contributed this plugin which
1084 counts received mails in categories (e. g. ham, spam, virus), spam
1085 score (as given by SpamAssassin) and check types.
1086 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1087 uses `mbmon' to gather information from sensors on the motherboard.
1088 * processes plugin: Collect detailed statistics for configured
1089 processes, that's process and thread count, CPU usage, resident
1090 segment size and pagefaults.
1091 * multimeter plugin: Peter Holik contributed a new plugin which
1092 queries multimeters.
1093 * sensors plugin: Lubos Stanek has put much effort into improving this
1094 plugin, including `extended naming', collection of voltage values
1095 and the possibility to ignore certain values.
1097 2006-12-21, Version 3.10.4
1098 * Max Kellermann has identified a bug in the server routine: When
1099 opening a socket fails the daemon will (re)try opening the socket in
1100 an endless loop, ultimately leading to a `EMFILE' error.
1102 2006-11-04, Version 3.10.3
1103 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1104 ntpd's reply was sent in more than one packet, the buffer size was
1105 calculated incorrectly, resulting in the reading of uninitialized or
1108 2006-11-01, Version 3.10.2
1109 * The sample config file has been improved.
1110 * Errors in the manpages have been corrected.
1111 * The ping-plugin now adds hosts during initialization, not during
1112 startup. This speeds up startup when no network connectivity is
1113 available. Also, the hosts are being added later when the network is
1115 * Improved BSD-support for the df-plugin.
1116 * Fixed syntax errors in the swap-plugin for Mac OS X.
1117 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1119 * Don't disable the mysql-plugin if connecting to the database fails
1120 during initialization. Instead, try again in increasing intervals.
1122 2006-07-19, Version 3.10.1
1123 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1124 the apcups cannot be reached, unconnected sockets will pile up and
1125 eventually lead to `Too many open files' errors.
1127 2006-07-09, Version 3.10.0
1128 * The `disk' plugin has been ported to Darwin.
1129 * The `battery' plugin should work on many Apple computers now.
1130 * The `traffic' plugin can now ignore certain interfaces. Also,
1131 statistics for sent/received packets and errors have been added.
1132 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1133 to Anthony Gialluca for contributing this plugin and providing me
1134 with a test environment :)
1135 * A plugin for monitoring an NTP instance and the local clock drift
1138 2006-06-25, Version 3.9.4
1139 * The Solaris code in the `swap' plugin has been changed to reflect
1140 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1142 * The debugging system has been fixed to work with the Sun libc.
1143 * When built without librrd the variable `operating_mode' could be
1144 uninitialized. Thanks to David Elliot for reporting the bug.
1146 2006-06-01, Version 3.9.3
1147 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1148 operating systems also profit from the changes, but I wasn't able to
1150 * Changed the build system to find the netinet-includes under FreeBSD
1151 and therefore successfully build the `liboping' library there.
1153 2006-05-09, Version 3.9.2
1154 * Applied a patch to the `liboping' library. Due to a bug in the
1155 sequence checking the `ping' plugin stopped working after
1156 approximately 7.6 days.
1158 2006-05-09, Version 3.8.5
1159 * Applied a patch to the `liboping' library. Due to a bug in the
1160 sequence checking the `ping' plugin stopped working after
1161 approximately 7.6 days.
1163 2006-04-21, Version 3.9.1
1164 * Build issues with Solaris and possible other architectures have been
1166 * Problems when building the `apache'-plugin without `libcurl' have
1168 * A bug in the `ping' plugin has been fixed. Sorry folks.
1170 2006-04-02, Version 3.9.0
1171 * A plugin to monitor the Apache webserver has been added.
1172 <http://httpd.apache.org/>
1173 * A plugin to collect statistics about virtual servers using VServer.
1174 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1176 * A plugin for wireless LAN cards has been added. It monitors signal
1177 strength, link quality and noise ratio..
1178 * A plugin for Apple hardware sensors has been added.
1179 * An option to compile collectd with different `step' and `heartbeat'
1180 settings has been added. The size of RRAs is no longer static but
1181 calculated based on the settings for `step' and `width'.
1182 * The `ping' plugin can now be configured to use a certain TTL.
1183 * A plugin to monitor the hardware sensors of Apple computers has been
1185 * The plugins `cpu', `memory', `processes' and `traffic' have been
1186 ported to Mach/Darwin (Mac OS X).
1187 * The `log mode' has been contributed by Christophe Kalt. It writes
1188 the data into text files rather than RRD files.
1190 2006-04-09, Version 3.8.4
1191 * Applied patch by Vincent Stehlé which improves the disk-name
1192 resolution in the `hddtemp' plugin for Linux systems.
1194 2006-04-02, Version 3.8.3
1195 * Applied a patch by James Byers: The MySQL plugin was not working
1196 with MySQL 5.0.2 or later.
1198 2006-03-14, Version 3.8.2
1199 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1200 the GNU libc, because it points to `/etc/fstab' rather than
1203 2006-03-13, Version 3.8.1
1204 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1205 * Fixes in the debian `postinst' and `init.d' scripts.
1207 2006-03-09, Version 3.8.0
1208 * The `ping' plugin no longer uses `libping' but a self written
1209 library named `liboping'. With this library it's possible to ping
1210 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1212 2006-02-18, Version 3.7.2
1213 * A simple bug in the `battery' plugin has been fixed. It should now
1214 work with ACPI based batteries as well. Thanks to Sebastian for
1216 * Fixing a bug that prevented collectd to be built without librrd.
1217 Thanks to Werner Heuser for reporting it.
1219 2006-02-04, Version 3.7.1
1220 * The new network code has been improved to build with older versions
1222 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1223 to Tommie Gannert for this patch.
1225 2006-01-30, Version 3.7.0
1226 * The `battery' plugin has been added. It collects information about
1228 * The MySQL plugin has been improved: It now writes two more RRD
1229 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1230 * The `cpufreq' plugin now reads another file since the file it did
1231 read so far causes much overhead in the kernel. Also, you need root
1232 to read the old file, but not to read the new one.
1233 * The `hddtemp' plugin can now be configured to connect to another
1234 address and/or port than localhost.
1235 * The `df' plugin now prefers `statvfs' over `statfs'.
1236 * The network code has been rewritten. collectd now supports unicast
1237 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1238 be set in the configfile.
1240 2006-01-24, Version 3.6.2
1241 * Due to a bug in the configfile handling collectd wouldn't start in
1242 client mode. This released fixes this.
1244 2006-01-20, Version 3.6.1
1245 * Due to a bug in `configure.in' all modules and the binary were
1246 linked against `libmysqlclient'. This issue is solved by this
1249 2006-01-17, Version 3.6.0
1250 * A config file has been added. This allows for loading only specific
1252 * A `df' plugin has been added.
1253 * A `mysql' plugin has been added.
1254 * The `ping' plugin doesn't entirely give up hope when a socket error
1255 occurred, but will back of and increase the intervals between tries.
1257 2006-01-21, Version 3.5.2
1258 * Fixed yet another bug in the signal handling.. Stupid typo..
1259 * Improved the ping plugin to not give up on socket errors (backport
1262 2005-12-18, Version 3.5.1
1263 * The PID-file is now deleted correctly when shutting down the daemon.
1264 * SIGINT and SIGTERM are now handled correctly.
1266 2005-12-16, Version 3.5.0 (Revision 326)
1267 * A bug in the `load' module under Solaris has been fixed.
1268 * The `users' module has been contributed by Sebastian Harl. It counts
1269 currently logged in users.
1270 * The CPU module now works under FreeBSD without the use of
1271 `libstatgrab', however SMP support is missing.
1272 * The default directories for the RRD files and the PID file now
1273 depend on the compile time setting of `localstatedir'.
1275 2005-11-15, Version 3.4.0 (Revision 236)
1276 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1277 from gentoo's bugzilla for writing the patch.
1278 * The build dependency for librrd has been removed. Binaries built
1279 without librrd are client-only and will multicast their value as
1280 with the `-c' argument.
1281 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1282 * The newly introduced `-f' switch prevents daemon initialization
1283 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1284 Barcellos for this patch.
1286 2005-11-04, Version 3.3.0 (Revision 216)
1287 * New modules have been added:
1288 - `serial', for monitoring traffic on the serial interfaces
1289 - `nfs', for graphing NFS procedure calls
1290 - `tape', traffic from/to tape devices
1291 * The memory.rrd now accepts more than 4Gig of memory.
1293 2005-10-26, Version 3.2.0 (Revision 200)
1294 * Support for graphing the processes has been added (thanks to Lyonel
1296 * If reading from hddtemp fails collectd will increase the time
1297 between polls up to one day.
1298 * The init.d files have been improved.
1299 * Problems with the spec file have been fixed.
1301 2005-10-16, Version 3.1.0 (Revision 194)
1302 * Added the `setsid' syscall to the startup code.
1303 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1305 2005-09-30, Version 3.0.0 (Revision 184)
1306 * The ability to send/receive data to/from the network (think
1307 multicast) has been added.
1308 * Modules have been split up into shared libraries can be loaded at
1309 runtime. The biggest advantage is that the core program doesn't need
1310 to be linked against an external library.
1311 * A patch by George Kargiotakis has been applied: It fixes the sensors
1312 behaviour then more than one sensor is being queried.
1314 2005-09-16, Version 2.1.0 (Revision 172)
1315 * A module for swap statistics has been added.
1317 2005-09-09, Version 2.0.0 (Revision 135)
1318 * Filenames can no longer be configured at program startup. The only
1319 options as of this version are the directory and ping hosts.
1320 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1321 Soft-IRQ statistics are added to `System'.
1322 * Diskstats now collect read and write bytes, not sectors.
1323 * Ping statistics can now be collected for more than one host. There
1324 is no default any more: If no host is given no host will be pinged.
1325 * A self-written patch for libping has been applied so it builds
1328 2005-09-01, Version 1.8.1 (Revision 123)
1329 * Much improved configure-script: libraries and features may now be
1331 * More detailed warnings/error messages when RRD update fails.
1333 2005-08-29, Version 1.8.0:
1334 * Support for collecting disk statistics under Solaris.
1336 2005-08-25, Version 1.7.0:
1337 * Support for libstatgrab[1] for load, memory usage and network
1338 traffic. CPU- and disk-usage are not (yet) supported, since
1339 libstatgrab returns insufficient information. I will contact the
1341 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1342 aren't necessarily counted linear which is now handled correctly.
1343 [1]: http://www.i-scream.org/libstatgrab/
1345 2005-08-21, Version 1.6.0:
1346 * Basic support for Solaris: System load and cpu-usage can be
1347 collected under Solaris, too. Other stats will follow later.
1348 * Many fixes in the autoconf-script
1349 * Collection/Museum scripts have been added under contrib/museum
1350 * collectd may now be started in unprivileged mode, though ping
1351 statistics will not work.
1353 2005-07-17, Version 1.5.1:
1354 * Diskstats-RRDs now use major/minor for naming. Some systems have
1355 weird strings as disk-names..
1357 2005-07-17, Version 1.5:
1358 * A new module, diskstats, has been added. It collects information
1359 about the disks and partitions.
1361 2005-07-11, Version 1.4.2:
1362 * The meminfo module has been changed to work with more platforms
1363 and/or kernel versions.
1365 2005-07-10, Version 1.4.1: Correct traffic stats
1366 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1367 forgot to correct when I changed that module.
1369 2005-07-09, Version 1.4: More traffic stats
1370 * Traffic is now collected for all interfaces that can be found
1371 * Temperature-statistics are read from lm-sensors if available
1373 2005-07-08, Version 1.3: CPU stats
1374 * Collecting CPU statistics now
1376 2005-07-12, Version 1.2: Using syslog
1377 * collectd is now using the syslog facility to report errors, warnings
1379 * The default directory is now /var/db/collectd
1381 2005-07-10, Version 1.1: Minor changes
1382 * Nothing really useful to say ;)
1384 2005-07-09, Version 1.0: Initial Version
1385 * The following modules are provided:
projects / collectd.git / blob
