2400 forked. The JVM internally creates threads that are lost when
2401 forking. This means that Java-based plugins are now configured
2402 during the init-phase, i. e. later than other plugins.
2403 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2404 to Alan Pevec for the patch.
2405 * network plugin: Fix the handling of the “CacheFlush” option: The

2428 libtool 2.2 has been added.
2429 * collectd: Two bugs with the threshold checking have been fixed. The
2430 first one prevented thresholds to be checked at all, the second one
2431 caused wrong behavior with the persistency option. Thanks to Andrés
2432 J. Díaz for fixing these problems.
2433 * collectd: Handling of the `Include' configuration option has been
2435 * rrdtool plugin: Make sure initialization is run only once. This
2436 resolves problems under Solaris and potentially other systems.
2437 Thanks to Amit Gupta for reporting this bug.
2438 * java plugin: Make it possible to use dots ('.') instead of slashes
2439 ('/') as the class separator. Thanks to Randy Rizun for pointing

2455 multicast traffic from Ganglia's gmond daemon.
2456 * java plugin: The new java plugin exports the collectd API to Java,
2457 making it possible to write extensions to collectd in Java.
2458 * memcachec plugin: The new memcachec plugin queries data from a
2459 memcached daemon and parses it similar to the cURL plugin. Thanks to
2460 Doug MacEachern for the initial code.

2520 for many fixes and providing a build system for many platforms,
2521 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2522 providing an OpenBSD system.
2523 * collectd: Two bugs with the threshold checking have been fixed. The
2524 first one prevented thresholds to be checked at all, the second one
2525 caused wrong behavior with the persistency option. Thanks to Andrés
2526 J. Díaz for fixing these problems.

2543 * filter subsystem: Allow `Chains' without default targets.
2544 * liboping: A patch to comply with strict aliasing rules has been
2546 * timediff match: Fix a typo: The match was registered with a wrong
2547 name which prevented this match to be used as documented. Thanks to
2548 Bruno Prémont for finding this problem.
2549 * bind plugin: Fix collection of the cached RR sets. The number of RR
2550 sets currently in the cache was collected as a counter value, which
2551 is nonsense. Thanks to Bruno Prémont for implementing this.
2552 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2553 primarily BSDs, don't take it well and crash.
2554 * oracle plugin: Portability to 64 bit systems has been improved.
2555 * postgresql plugin: The default configuration has been improved.
2556 * rrdtool plugin: Fix a possible race condition: If the network plugin
2557 is brought and dispatches a value before the rrdtool plugin is
2558 initialized, the daemon may crash.
2560 2009-02-22, Version 4.6.1

2565 for finding and fixing most of them.
2566 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2567 faults. Thanks to Peter Holik for his patch.
2569 2009-02-16, Version 4.6.0
2570 * collectd: Added the `filter chain' infrastructure, which allows the
2571 user to use `matches' and `targets' to control value processing.
2572 * collectd: The new `-T' command line argument allows more in-depth
2573 testing of a configuration. Thanks to Doug MacEachern for the patch.
2574 * collectd-nagios: The Nagios integration command has been updated to
2575 use libcollectdclient. The `percentage' aggregation function has
2576 been added. Thanks to Fabian Linzberger for the patch.

2592 example for native OpenBSD support, has been added. Thanks to Simon
2593 Kuhnle for the patch.
2594 * csv plugin: Make it possible to write values to STDOUT instead of
2595 files. This is meant for testing purposes mostly. The output written
2596 to STDOUT is compatible with the exec plugin. Thanks to Doug
2597 MacEachern for the patch.
2598 * curl plugin: This new plugin can be used to read web pages and parse
2599 them using the same mechanism that's used in the tail plugin.
2600 * dbi plugin: This new plugin allows you to connect to a variety of
2601 relational databases and use SQL to gather custom statistics from
2602 it. It is similar to the already existing PostgreSQL plugin but uses
2603 libdbi to communicate with the database(s).
2604 * interface plugin: Use the ignorelist framework when selecting /
2605 ignoring interfaces. This allows one to use regular expressions to
2606 select interfaces, too.
2607 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2608 Thanks to Bruno Prémont for this patch.
2609 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

2622 * perl plugin: Export the newly added plugin_write() to Perl plugins.
2623 * perl plugin: Added support for `notification meta data'.
2624 * perl plugin: Added support for the `filter chain' infrastructure by
2625 allowing plugins to register `matches' and `targets'.
2626 * postgresql plugin: The preferred configuration syntax has been
2627 updated to be in line with the syntax used by the new dbi and oracle
2628 plugins. The compatibility code for the old syntax is present.
2629 Support for the new `Result' blocks and the interval parameter has
2631 * processes plugin: Stacksize and virtual memory usage statistics have
2632 been added. Portability fixes.
2633 * rrdcached plugin: This new plugin uses the (still in development)
2634 RRD accelerator daemon, rrdcached. This daemon works very similar to
2635 the original rrdtool plugin of collectd, but adds some more nice
2637 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2640 2009-05-09, Version 4.5.4
2641 * Build system, various plugins: Many build fixes for FreeBSD,
2642 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2643 for many fixes and providing a build system for many platforms,
2644 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2645 providing an OpenBSD system.
2646 * collectd: Fix a potential race condition when creating directories.
2647 * battery plugin: Don't complain about a missing directory every

2652 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2653 Tomasz Pala for the patch.
2654 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2656 * rrdtool plugin: Fix a possible race condition: If the network plugin
2657 is initialized and dispatches a value before the rrdtool plugin is
2658 initialized, the daemon may crash.
2659 * memory plugin: Fix a potential problem under Solaris.
2661 2009-02-22, Version 4.5.3
2662 * build system: The check for libupsclient even when `pkg-config' is
2664 * collectd: Fix error handling in the global cache.
2665 * Collectd::Unixsock: Error handling has been improved.
2666 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

2669 faults. Thanks to Peter Holik for his patch.
2670 * tcpconns plugin: An endianness problem has been fixed in the *BSD
2671 code. Thanks to "thated" for reporting this.
2673 2009-01-02, Version 4.5.2
2674 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2675 file may be in both locations, especially when the database was
2676 installed in a non-standard path. Thanks to Dusty Doris for
2678 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2679 Solaris, in the configure script automatically.
2680 * build system, tcpconns plugin: Check for `kvm_nlist' and
2681 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2682 library with similar functions to the BSD variant, but doesn't
2683 provide these necessary functions.
2684 * collectd.conf(5): Various fixes and clarifications.
2685 * collectd: Remove a GNUism (unnamed unions), thus improving
2687 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2688 This solves portability problems, especially for Solaris.
2689 * dns plugin: Fix a portability problem with NetBSD.
2690 * filecount plugin: Fix an off-by-one error. This error may cause a
2692 * network plugin: Fix the handling of `type' in the network protocol.
2693 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2694 much larger buffer. This caused the `type' to be transferred much
2695 more often than necessary. In some cases, e. g. the `cpu' and
2696 `cpufreq' plugins being used at the same time, data may be corrupted
2697 in those files. Thanks to Bruno Prémont for debugging and reporting
2699 * processes plugin: Fix a possible segmentation fault when specifying
2700 invalid configuration options.
2701 * unixsock plugin: Make sure the initialization function is run only
2702 once. This resolves a file descriptor leak under systems which run
2703 the initialization more than once, such as Solaris.
2705 2008-10-16, Version 4.5.1
2706 * build system: Change `--enable-<plugin>' to abort with an error if
2707 dependencies are not met. Thanks to Bruno Prémont for the patch.
2708 Also, the poisoning of various string functions has been restricted
2710 * collectd: Fix a memory leak in the global value cache. With every
2711 *missing* value a couple of bytes would be leaked. Another memory
2712 leak in the configuration handling code has been fixed. Thanks to
2713 Niraj Tolia for reporting these issues.
2714 * collectd: Fix an off-by-one error in the ignorelist functionality.
2715 When using regular expressions, the last character would be missing,
2716 possibly matching differently from what one would expect.
2717 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2719 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2720 Linzberger for reporting the bug.
2721 * iptables plugin: Fix an off-by-one error. If a string was just one
2722 character too long, it was truncated instead of reporting an error.
2723 * network plugin: Fix a memory leak in the configuration handling
2724 code. Thanks to Niraj Tolia for reporting this issue.
2725 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2726 * postgresql plugin: Don't reopen connection during reinitialization.
2727 This fixes a bug under Solaris and potentially other platforms.
2728 Missing calls to `PQclear' have been added, too. This fixes memory
2729 leaks. Thanks to ``Admin'' for reporting these bugs.
2730 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2732 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2733 problems with some `libc's. Thanks to Matthias Lay for reporting the
2736 2008-09-04, Version 4.5.0
2737 * collectd: Added the ability to flush certain identifiers.
2738 * collectd: The concept of `notification meta data' has been
2740 * filecount plugin: The new filecount plugin counts the number of
2741 files in a directory and its subdirectories.
2742 * ipmi plugin: Sensor names have been changed to ensure unique names.
2743 Notifications upon added and removed sensors can now be generated.
2744 * notify_desktop plugin: This new plugin sends notifications to the
2745 X desktop using the structure defined in the `Desktop Notification
2747 * notify_email plugin: This new plugin sends out notifications via
2748 email, using the `esmtp' library.
2749 * onewire plugin: The new experimental(!) onewire plugin reads values,
2750 such as temperatures, from sensors connected to the computer via the
2752 * perl plugin: Improved synchronized access to internal data structures
2753 and fixed a possible dead-lock.
2754 * perl plugin: Added the ability to flush certain identifiers and marked
2755 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2757 * perl plugin: Added the ability to configure Perl plugins.
2758 * postgresql plugin: The new postgresql plugin collects statistics
2759 about or from a PostgreSQL database.
2760 * processes plugin: The `ProcessMatch' option has been added.
2761 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2763 * tcpconns plugin: This plugin has been ported to OpenBSD.
2764 * thermal plugin: The new thermal plugin collects system temperatures
2765 using Linux ACPI thermal zone data.
2767 2009-01-02, Version 4.4.5
2768 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2769 file may be in both locations, especially when the database was
2770 installed in a non-standard path. Thanks to Dusty Doris for
2772 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2773 Solaris, in the configure script automatically.
2774 * collectd.conf(5): Various fixes and clarifications.
2775 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2776 portability problems, especially for Solaris.
2777 * dns plugin: Fix a portability problem with NetBSD.
2778 * network plugin: Fix the handling of `type' in the network protocol.
2779 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2780 much larger buffer. This caused the `type' to be transferred much
2781 more often than necessary. In some cases, e. g. the `cpu' and
2782 `cpufreq' plugins being used at the same time, data may be corrupted
2783 in those files. Thanks to Bruno Prémont for debugging and reporting
2785 * unixsock plugin: Make sure the initialization function is run only
2786 once. This resolves a file descriptor leak under systems which run
2787 the initialization more than once, such as Solaris.
2789 2008-10-16, Version 4.4.4
2790 * build system: Change `--enable-<plugin>' to abort with an error if
2791 dependencies are not met. Thanks to Bruno Prémont for the patch.
2792 Also, the poisoning of various string functions has been restricted
2794 * collectd: Fix a memory leak in the global value cache. With every
2795 *missing* value a couple of bytes would be leaked. Another memory
2796 leak in the configuration handling code has been fixed. Thanks to
2797 Niraj Tolia for reporting these issues.
2798 * collectd: Fix an off-by-one error in the ignorelist functionality.
2799 When using regular expressions, the last character would be missing,
2800 possibly matching differently from what one would expect.
2801 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2803 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2804 Linzberger for reporting the bug.
2805 * network plugin: Fix a memory leak in the configuration handling
2806 code. Thanks to Niraj Tolia for reporting this issue.
2807 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2808 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2809 problems with some `libc's. Thanks to Matthias Lay for reporting the
2812 2008-09-01, Version 4.4.3
2813 * collectd: Fix a memory leak in the threshold checking code.
2814 * memcached plugin: Fix a too short timeout and a related file
2816 * memory plugin: A typo in the libstatgrab code has been fixed.
2817 * snmp plugin: Fix a possible memory leak.
2819 2008-07-15, Version 4.4.2
2820 * build system: Use pkg-config to detect the upsclient library.
2821 * collectd: Try even harder to determine the endianness of the
2822 architecture collectd is being built on.
2823 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2825 * dns plugin: Fix compilation errors with BIND versions 19991001
2827 * network plugin: Bugfix in the init routine: The init function
2828 cleared a buffer regardless of its contents. This could lead to lost
2829 values under Solaris.
2830 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2831 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2833 * wireless plugin: Work around incorrect noise and power values
2834 returned by some broken drivers.
2836 2008-06-03, Version 4.4.1
2837 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2838 to kyrone for reporting this.
2839 * collectd: Fixed min/max output in notifications generated by
2841 * collectd-nagios: Fix the protocol used to communicate with the
2843 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2844 initialization has errors. An issue with Perl 5.10 has been fixed.
2845 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2846 René Rebe and Siegmund Gorr for reporting this.
2848 2008-05-06, Version 4.4.0
2849 * collectd: Internal code cleanups.
2850 * collectd: Added support for a `Flush' command in the unixsock and
2851 exec plugins. This command can be used to force a plugin (or all) to
2852 flush its values to disk.
2853 * collectd: Thresholds can now be configured to apply to one data
2854 source only, making it possible to configure different thresholds
2855 for each data source.
2856 * apache, nginx plugins: Added the possibility to disable host and/or
2858 * ascent plugin: The new ascent plugin reads and parses the statistics
2859 page of an Ascent server.
2860 * cpu plugin: Support for the statgrab library has been added.
2861 * disk plugin: The possibility to ignore certain disks or collect only
2862 specific disks has been added.
2863 * disk plugin: Support for the statgrab library has been added.
2864 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
2865 sensor values via IPMI, the intelligent platform management
2867 * iptables plugin: The iptc library that is used by the iptables
2868 plugin has been added to the distribution, because it is not
2869 provided by all distributions and removed from at least one.
2870 * powerdns plugin: The new powerdns plugin reads statistics from an
2871 authoritative or a recursing PowerDNS name server.
2872 * rrdtool plugin: The size of the files generated with the default
2873 configuration has been decreased.
2874 * tail plugin: The new tail plugin can be used to gather statistics by
2875 continuously reading from log files.
2876 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2877 TeamSpeak2 server and collects statistics about the number of users
2878 and number of channels.
2879 * users plugin: Support for the statgrab library has been added.
2880 * vmem plugin: The new vmem plugin collects very detailed statistics
2881 about the virtual memory subsystem of Linux.
2883 2008-08-30, Version 4.3.4
2884 * Build system: Improved detection of and linking with the statgrab
2886 * collectd: Portability fixes, especially to determine endianness more
2888 * Various plugins: Fix format strings.
2889 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2890 again has been applied.
2891 * memcached plugin: Fix a too short timeout and a related file
2893 * memory plugin: A typo in the libstatgrab code has been fixed.
2894 * network plugin: A fix in the initialization function solves problems
2896 * nginx plugin: A thread-unsafe function has been replaced.
2897 * vserver plugin: A thread-unsafe function has been replaced.
2898 * wireless plugin: A work-around for broken wireless drivers has been
2901 2008-04-22, Version 4.3.3
2902 * build system: Improved detection of several libraries, especially if
2903 they are in non-standard paths.
2904 * build system: Portability fixes: Automatically define "_REENTRANT"
2905 if the libc expects it.
2906 * collectd: Error and warning messages have been improved.
2907 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2909 * apache plugin: Allocate new memory when reading a webpage instead of
2910 using a buffer of static size.
2911 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2913 * hddtemp plugin: Error and warning messages have been improved.
2914 * sensors plugin: Fix sensor collection for some chip types.
2916 2008-03-29, Version 4.3.2
2917 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2918 `Persist' threshold options.
2919 * collectd: Fix handling of missing values in the global value cache.
2920 * collectd: Improved error messages when parsing the configuration.
2921 * sensors plugin: Fix temperature collection with libsensors4.
2922 * unixsock plugin: Fix mixed input and output operation on streams.
2923 * wireless plugin: Fix reading noise value.
2925 2008-03-05, Version 4.3.1
2926 * exec plugin: Set supplementary group IDs.
2928 + Use `memcpy' when constructing/parsing a package to avoid
2929 alignment problems on weird architectures, such as Sparc.
2930 + Translate doubles to/from the x86 byte representation to ensure
2931 cross-platform compatibility.
2932 * ping plugin: Correct the handling of the `TTL' setting.
2933 * swap plugin: Reapply a patch for Solaris.
2934 * tcpconns plugin: Portability improvements.
2936 2008-02-18, Version 4.3.0
2937 * collectd: Notifications have been added to the daemon. Notifications
2938 are status messages that may be associated with a data instance.
2939 * collectd: Threshold checking has been added to the daemon. This
2940 means that you can configure threshold values for each data
2941 instance. If this threshold is exceeded a notification will be
2943 * collectd: The new `FQDNLookup' option tells the daemon to use the
2944 full qualified domain name as the hostname, not just the host part
2945 es returned by `gethostname(2)'.
2946 * collectd: Support for more than one `TypesDB' file has been added.
2947 This is useful when one such file is included in a package but one
2948 wants to add custom type definitions.
2949 * collectd: The `Include' config option has been expanded to handle
2950 entire directories and shell wildcards.
2951 * collectdmon: The new `collectdmon' binary detects when collectd
2952 terminates and automatically restarts it again.
2953 * csv plugin: The CSV plugin is now able to store counter values as a
2954 rate, using the `StoreRates' configuration option.
2955 * exec plugin: Handling of notifications has been added and the
2956 ability to pass arguments to the executed programs has been added.
2957 * hddtemp plugin: The new `TranslateDevicename' option lets you
2958 disable the translation from device names to major-minor-numbers.
2959 * logfile plugin: Handling of notifications has been added.
2960 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2961 domain name lookups in this plugin.
2962 * perl plugin: Many internal changes added support for handling multiple
2963 threads making the plugin reasonably usable inside collectd. The API has
2964 been extended to support notifications and export global variables to
2965 Perl plugins; callbacks now have to be identified by name rather than a
2966 pointer to a subroutine. The plugin is no longer experimental.
2967 * uuid plugin: The new UUID plugin sets the hostname to an unique
2968 identifier for this host. This is meant for setups where each client
2969 may migrate to another physical host, possibly going through one or
2970 more name changes in the process. Thanks to Richard Jones from
2971 Red Hat's Emerging Technology group for this plugin.
2972 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2973 CPU, disk and network statistics about guest systems on the same
2974 physical server. Thanks to Richard Jones from Red Hat's Emerging
2975 Technology group for this plugin.
2977 2008-04-22, Version 4.2.7
2978 * build system: Improved detection of several libraries, especially if
2979 they are in non-standard paths.
2980 * build system: Portability fixes: Automatically define "_REENTRANT"
2981 if the libc expects it.
2982 * collectd: Error and warning messages have been improved.
2983 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2985 * apache plugin: Allocate new memory when reading a webpage instead of
2986 using a buffer of static size.
2987 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2989 * hddtemp plugin: Error and warning messages have been improved.
2990 * sensors plugin: Fix sensor collection for some chip types.
2992 2008-03-29, Version 4.2.6
2993 * collectd: Improved error messages when parsing the configuration.
2994 * sensors plugin: Fix temperature collection with libsensors4.
2995 * unixsock plugin: Fix mixed input and output operation on streams.
2996 * wireless plugin: Fix reading noise value.
2998 2008-03-04, Version 4.2.5
2999 * apache plugin: Improved initialization and error messages.
3000 * exec plugin: Set supplementary group IDs.
3002 + Create separate threads for reading from the socket and parsing
3003 and dispatching incoming packets. Versions prior to this may have
3004 problems in high-load situations, where the socket receive buffers
3005 overflows, resulting in gaps in the data.
3006 + Use `memcpy' when constructing/parsing a package to avoid
3007 alignment problems on weird architectures, such as Sparc.
3008 + Translate doubles to/from the x86 byte representation to ensure
3009 cross-platform compatibility.
3010 * ping plugin: Correct the handling of the `TTL' setting.
3011 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3012 * swap plugin: Reapply a patch for Solaris.
3013 * tcpconns plugin: Portability improvements.
3015 2008-01-21, Version 4.2.4
3016 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3017 the permission on the socket as documented in the manpage. Thanks to
3018 Evgeny Chukreev for fixing this issue.
3019 * collectd: The documentation has been improved.
3021 2007-12-28, Version 4.2.3
3022 * sensors plugin: Updated the plugin to build and work with version 3
3023 of the libsensors library.
3025 2007-12-15, Version 4.2.2
3026 * nginx plugin: Incorrect comparison of strings lead to a segfault
3027 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3029 * logfile plugin: The config option `Timestamp' was handled
3030 incorrectly and basically always active. Thanks to Luke Heberling
3033 2007-11-08, Version 4.2.1
3034 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3035 enabled on the host.
3036 * snmp plugin: Fix a memory leak.
3038 2007-10-27, Version 4.2.0
3039 * collectd: The new config option `Include' lets you include other
3040 configfiles and thus split up your config into smaller parts. This
3041 may be especially interesting for the snmp plugin to keep the data
3042 definitions separate from the host definitions.
3043 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3044 (number of connections, octets and packets for each service and
3045 destination). Thanks to Sebastian Harl for this plugin.
3046 * memcached plugin: The new `memcached' plugin connects to a memcached
3047 daemon process and collects statistics of this distributed caching
3048 system. Thanks to Antony Dovgal for contributing this plugin.
3049 * nginx plugin: The new `nginx' plugin reads the status page of an
3050 nginx daemon and saves the handled connections and requests.
3051 * perl plugin: Many changes, including the added `EnableDebugger'
3052 config option which lets you debug your Perl plugins more easily.
3053 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3054 be more thread-safe otherwise by locking calls to the library.
3055 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3056 correct the values returned by SNMP-agents. If a <data> block is
3057 defined as `table' the instance is now optional. The sequence number
3058 is used as the type-instance in this case. The new `InstancePrefix'
3059 option allows to add arbitrary prefixes to the type-instance.
3060 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3061 certain TCP connections and what state they're in. This can be used
3062 to see how many connections your FTP server has to handle or how
3063 many outgoing connections your mailserver has open.
3065 2008-01-11, Version 4.1.6
3066 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3067 the permission on the socket as documented in the manpage. Thanks to
3068 Evgeny Chukreev for fixing this issue.
3069 * collectd: The documentation has been improved.
3071 2007-12-27, Version 4.1.5

3075 of the libsensors library.
3077 2007-11-08, Version 4.1.4
3078 * Build system: Improve detection of the rrd library, especially if
3079 it's in a non-standard location.
3080 * Build system: A bug when parsing the argument for
3081 `--with-libnetsnmp' has been fixed.
3082 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3083 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3084 a deadlock or delay when shutting down the daemon.
3085 * snmp plugin: Fix a memory leak.
3087 2007-10-24, Version 4.1.3
3088 * collectd: A build issue under Solaris has been resolved by renaming
3090 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3091 be more thread-safe otherwise by locking calls to the library.
3093 2007-09-28, Version 4.1.2
3094 * apcups plugin: Fix reporting of the `load percent' data.
3095 * wireless plugin: Correct the handling of cards returning signal and
3096 noise quality as percentage.
3097 * perl plugin: Fix a possible buffer overflow in get_module_name().
3098 * build system: Further improve the detection of libraries.
3099 * netlink plugin: Build issues under some older versions of the Linux
3100 includes (i. e. Debian Sarge) have been fixed.
3101 * snmp plugin: Fix a potential segfault when a host times out. Add
3102 support for the `timeticks' type.
3104 2007-09-12, Version 4.1.1
3105 * Build system: The detection of `libnetlink' has been improved.
3106 * collectd: The documentation has been fixed in numerous places.
3107 * exec plugin: Setting the group under which to run a program has been
3109 * collectd: The `sstrerror' function was improved to work correctly
3110 with the broken GNU version of `strerror_r'.
3111 * collectd: Write an error message to STDERR when loading of a plugin
3113 * apcups plugin: Fix the `types' used to submit the values: They still
3114 has an `apcups_' prefix which doesn't work anymore.
3115 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3116 whatever the client thinks is `now'..
3118 2007-09-01, Version 4.1.0
3119 * Build system: The build system has been changed to automatically
3120 disable all plugins, which are missing dependencies. The dependency
3121 checking has been removed from the plugins themselves to remove
3123 * Flexible interval: The interval of collected data is now sent along
3124 with the data itself over the network, so that the interval-settings
3125 of server and clients no longer needs to match.
3126 * netlink plugin: The new `netlink' plugin connects to the Linux
3127 kernel using a netlink socket and uses it to query information about
3128 interfaces, qdiscs and classes.
3129 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3130 to not block data collection.
3131 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3132 network devices, such as switches, routers, thermometers, rack
3133 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3135 * unixsock plugin: Added the `LISTVAL' command.
3136 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3137 of music played with xmms.
3139 2007-09-28, Version 4.0.9
3140 * apcups plugin: Fix reporting of the `load percent' data.
3141 * wireless plugin: Correct the handling of cards returning signal and
3142 noise quality as percentage.
3143 * perl plugin: Fix a possible buffer overflow in get_module_name().
3145 2007-09-12, Version 4.0.8
3146 * collectd: The `sstrerror' function was improved to work correctly
3147 with the broken GNU version of `strerror_r'.
3148 * collectd: Write an error message to STDERR when loading of a plugin
3150 * apcups plugin: Fix the `types' used to submit the values: They still
3151 has an `apcups_' prefix which doesn't work anymore.
3152 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3153 whatever the client thinks is `now'..
3155 2007-08-26, Version 4.0.7
3156 * documentation: Some typos have been fixed and some information has
3158 * build system: Many fixes for detecting libraries in unusual places,
3159 such as on RedHat systems. The affected libraries are `libcurl',
3160 `libmysql', and `libupsclient'.
3161 * network plugin: Allow the `Port' option to be specified as a number
3162 (i. e. without quotes).
3163 * nut plugin: A fix allows linking the nut plugin against
3164 libupsclient, version >= 2.2.0.
3165 * processes plugin: Fix a potential segmentation fault.
3167 2007-07-30, Version 4.0.6
3168 * sensors plugin: Fix the ignorelist functionality: Only the `type
3169 instance' was used to match against the list, but the documentation
3170 told otherwise. This release fixes the code, so it complies with the
3172 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3173 configuration messages will end up in the logging facility.
3174 * conrtib/fedora: The contributed specfile for Fedora has been
3177 2007-07-05, Version 4.0.5
3178 * Portability: More fixes for OpenBSD have been included.
3180 2007-06-24, Version 4.0.4

3188 2007-06-19, Version 4.0.3
3189 * cpu plugin: Fix the Darwin / Mac OS X code.
3190 * ping plugin: Use the return value of `getpid', not its address.
3191 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3192 initialized correctly.
3193 * configure: Added `--with-nan-emulation' to aid cross compilation.
3195 2007-06-12, Version 4.0.2
3196 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3197 they're given in numerically form.
3199 2007-06-07, Version 4.0.1
3200 * iptables plugin: A bug in the configuration routine has been fixed.
3201 Setting a comment in the configfile will no longer cause a
3204 2007-06-03, Version 4.0.0
3205 * collectd: The plugin-infrastructure has been changed to allow for
3206 more types of plugins, namely `write' and `log' plugins.
3207 * collectd: The read-function has been changed to read many plugins in
3208 parallel, using threads. Thus, plugins generally need to use
3209 thread-safe functions from now on.
3210 * collectd: The '-t' command line options allows to perform syntax tests
3211 of the configuration file and exit immediately.
3212 * csv plugin: The new `csv' plugin handles output to `comma separated
3214 * rrdtool plugin: The new `rrdtool' plugin handles output to
3215 RRD-files. Data can be cached to combine multiple updates into one
3216 write to increase IO-performance.
3217 * network plugin: The new `network' plugin handles IO via the network.
3218 It implements a different, much more extensible protocol which can
3219 combine many values in one packet, decreasing the number of UDP-
3220 packets being sent. It can read from and send to the network and
3221 with the appropriate configuration even forward packets to other
3223 * unixsock plugin: The new `unixsock' plugin provides an interface to
3224 communicate with the daemon while it is running. Right now the
3225 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3227 * perl plugin: The new `perl' plugin allows you to write extensions
3228 for collectd in the scripting-language Perl.
3229 * logfile plugin: The new `logfile' plugin writes logmessages to files
3230 or STDOUT or STDERR.
3231 * syslog plugin: The new `syslog' plugin sends logmessages to the
3232 system's syslog daemon.
3233 * entropy plugin: The new `entropy' plugin collects the amount of
3234 entropy currently being available to the system.
3235 * exec plugin: The new `exec' plugin forks child processes and reads
3236 back values provided by the forked processes.
3237 * iptables plugin: The new `iptables' plugin reads counters from
3238 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3240 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3241 to Peter Holik for contributing this plugin.
3242 * nut plugin: The new `nut' plugin connects the upsd of the `network
3243 ups tools' and reads information about the connected UPS.
3244 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3245 connections) field was added by Florent Monbillard.
3246 * collectd-nagios: The new `collectd-nagios' binary queries values
3247 from collectd, parses them and exits according to Nagios-standards.
3248 * manpages: The manpages have been improved a lot.
3250 2007-09-28, Version 3.11.7
3251 * wireless plugin: Correct the handling of cards returning signal and
3252 noise quality as percentage.
3254 2007-08-31, Version 3.11.6
3255 * processes plugin: Fix a potential segmentation fault.
3257 2007-05-29, Version 3.11.5
3258 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3259 * ntpd plugin: Fix a potential buffer overflow.
3260 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3261 were accounted as `zombies'.
3263 2007-04-10, Version 3.11.4
3264 * dns plugin: Change the order of includes to make the plugin compile
3267 2007-03-30, Version 3.11.3
3268 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3269 of the unused `COLLECT_KSTAT'.
3271 2007-02-11, Version 3.11.2
3272 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3273 NULL-pointer may have been passed to `printf' which causes a
3274 segfault with some libcs.
3276 2007-02-10, Version 3.11.1
3277 * df plugin: Some wrong defines have been fixed so the plugin works
3278 under Solaris again.
3279 * dns plugin: The usage of a struct has been fixed to work with
3281 * processes plugin: Some missing defines have been added so the plugin
3282 compiles cleanly under FreeBSD and presumably other UNIXes.
3284 2006-12-22, Version 3.11.0
3285 * collectd: The new command line option `-P' makes it easier for
3286 distributors to change the location of PID-files.
3287 * collectd: The daemon shuts down faster now which makes it easier to
3288 write init.d-scripts for it.
3289 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3290 caused problems every now and then.
3291 * df plugin: New config options allow to ignore certain mountpoints,
3292 filesystem types or devices.
3293 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3294 and interprets it. It collects traffic as well as qtype, opcode and
3296 * email plugin: Sebastian Harl has contributed this plugin which
3297 counts received mails in categories (e. g. ham, spam, virus), spam
3298 score (as given by SpamAssassin) and check types.
3299 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3300 uses `mbmon' to gather information from sensors on the motherboard.
3301 * processes plugin: Collect detailed statistics for configured
3302 processes, that's process and thread count, CPU usage, resident
3303 segment size and pagefaults.
3304 * multimeter plugin: Peter Holik contributed a new plugin which
3305 queries multimeters.
3306 * sensors plugin: Lubos Stanek has put much effort into improving this
3307 plugin, including `extended naming', collection of voltage values
3308 and the possibility to ignore certain values.
3310 2006-12-21, Version 3.10.4
3311 * Max Kellermann has identified a bug in the server routine: When
3312 opening a socket fails the daemon will (re)try opening the socket in
3313 an endless loop, ultimately leading to a `EMFILE' error.
3315 2006-11-04, Version 3.10.3
3316 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3317 ntpd's reply was sent in more than one packet, the buffer size was
3318 calculated incorrectly, resulting in the reading of uninitialized or
3321 2006-11-01, Version 3.10.2
3322 * The sample config file has been improved.
3323 * Errors in the manpages have been corrected.
3324 * The ping-plugin now adds hosts during initialization, not during
3325 startup. This speeds up startup when no network connectivity is
3326 available. Also, the hosts are being added later when the network is
3328 * Improved BSD-support for the df-plugin.
3329 * Fixed syntax errors in the swap-plugin for Mac OS X.
3330 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3332 * Don't disable the mysql-plugin if connecting to the database fails
3333 during initialization. Instead, try again in increasing intervals.
3335 2006-07-19, Version 3.10.1
3336 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3337 the apcups cannot be reached, unconnected sockets will pile up and
3338 eventually lead to `Too many open files' errors.
3340 2006-07-09, Version 3.10.0
3341 * The `disk' plugin has been ported to Darwin.
3342 * The `battery' plugin should work on many Apple computers now.
3343 * The `traffic' plugin can now ignore certain interfaces. Also,
3344 statistics for sent/received packets and errors have been added.
3345 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3346 to Anthony Gialluca for contributing this plugin and providing me
3347 with a test environment :)
3348 * A plugin for monitoring an NTP instance and the local clock drift
3351 2006-06-25, Version 3.9.4
3352 * The Solaris code in the `swap' plugin has been changed to reflect
3353 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3355 * The debugging system has been fixed to work with the Sun libc.
3356 * When built without librrd the variable `operating_mode' could be
3357 uninitialized. Thanks to David Elliot for reporting the bug.
3359 2006-06-01, Version 3.9.3
3360 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3361 operating systems also profit from the changes, but I wasn't able to
3363 * Changed the build system to find the netinet-includes under FreeBSD
3364 and therefore successfully build the `liboping' library there.
3366 2006-05-09, Version 3.9.2
3367 * Applied a patch to the `liboping' library. Due to a bug in the
3368 sequence checking the `ping' plugin stopped working after
3369 approximately 7.6 days.
3371 2006-05-09, Version 3.8.5
3372 * Applied a patch to the `liboping' library. Due to a bug in the
3373 sequence checking the `ping' plugin stopped working after
3374 approximately 7.6 days.
3376 2006-04-21, Version 3.9.1
3377 * Build issues with Solaris and possible other architectures have been
3379 * Problems when building the `apache'-plugin without `libcurl' have
3381 * A bug in the `ping' plugin has been fixed. Sorry folks.
3383 2006-04-02, Version 3.9.0
3384 * A plugin to monitor the Apache webserver has been added.
3385 <http://httpd.apache.org/>
3386 * A plugin to collect statistics about virtual servers using VServer.
3387 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3389 * A plugin for wireless LAN cards has been added. It monitors signal
3390 strength, link quality and noise ratio..
3391 * A plugin for Apple hardware sensors has been added.
3392 * An option to compile collectd with different `step' and `heartbeat'
3393 settings has been added. The size of RRAs is no longer static but
3394 calculated based on the settings for `step' and `width'.
3395 * The `ping' plugin can now be configured to use a certain TTL.
3396 * A plugin to monitor the hardware sensors of Apple computers has been
3398 * The plugins `cpu', `memory', `processes' and `traffic' have been
3399 ported to Mach/Darwin (Mac OS X).
3400 * The `log mode' has been contributed by Christophe Kalt. It writes
3401 the data into text files rather than RRD files.
3403 2006-04-09, Version 3.8.4
3404 * Applied patch by Vincent Stehlé which improves the disk-name
3405 resolution in the `hddtemp' plugin for Linux systems.
3407 2006-04-02, Version 3.8.3
3408 * Applied a patch by James Byers: The MySQL plugin was not working
3409 with MySQL 5.0.2 or later.
3411 2006-03-14, Version 3.8.2
3412 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3413 the GNU libc, because it points to `/etc/fstab' rather than
3416 2006-03-13, Version 3.8.1
3417 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3418 * Fixes in the debian `postinst' and `init.d' scripts.
3420 2006-03-09, Version 3.8.0
3421 * The `ping' plugin no longer uses `libping' but a self written
3422 library named `liboping'. With this library it's possible to ping
3423 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3425 2006-02-18, Version 3.7.2
3426 * A simple bug in the `battery' plugin has been fixed. It should now
3427 work with ACPI based batteries as well. Thanks to Sebastian for
3429 * Fixing a bug that prevented collectd to be built without librrd.
3430 Thanks to Werner Heuser for reporting it.
3432 2006-02-04, Version 3.7.1
3433 * The new network code has been improved to build with older versions
3435 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3436 to Tommie Gannert for this patch.
3438 2006-01-30, Version 3.7.0
3439 * The `battery' plugin has been added. It collects information about
3441 * The MySQL plugin has been improved: It now writes two more RRD
3442 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3443 * The `cpufreq' plugin now reads another file since the file it did
3444 read so far causes much overhead in the kernel. Also, you need root
3445 to read the old file, but not to read the new one.
3446 * The `hddtemp' plugin can now be configured to connect to another
3447 address and/or port than localhost.
3448 * The `df' plugin now prefers `statvfs' over `statfs'.
3449 * The network code has been rewritten. collectd now supports unicast
3450 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3451 be set in the configfile.
3453 2006-01-24, Version 3.6.2
3454 * Due to a bug in the configfile handling collectd wouldn't start in
3455 client mode. This released fixes this.
3457 2006-01-20, Version 3.6.1
3458 * Due to a bug in `configure.in' all modules and the binary were
3459 linked against `libmysqlclient'. This issue is solved by this
3462 2006-01-17, Version 3.6.0
3463 * A config file has been added. This allows for loading only specific
3465 * A `df' plugin has been added.
3466 * A `mysql' plugin has been added.
3467 * The `ping' plugin doesn't entirely give up hope when a socket error
3468 occurred, but will back of and increase the intervals between tries.
3470 2006-01-21, Version 3.5.2
3471 * Fixed yet another bug in the signal handling.. Stupid typo..
3472 * Improved the ping plugin to not give up on socket errors (backport
3475 2005-12-18, Version 3.5.1
3476 * The PID-file is now deleted correctly when shutting down the daemon.
3477 * SIGINT and SIGTERM are now handled correctly.
3479 2005-12-16, Version 3.5.0 (Revision 326)
3480 * A bug in the `load' module under Solaris has been fixed.
3481 * The `users' module has been contributed by Sebastian Harl. It counts
3482 currently logged in users.
3483 * The CPU module now works under FreeBSD without the use of
3484 `libstatgrab', however SMP support is missing.
3485 * The default directories for the RRD files and the PID file now
3486 depend on the compile time setting of `localstatedir'.
3488 2005-11-15, Version 3.4.0 (Revision 236)
3489 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3490 from gentoo's bugzilla for writing the patch.
3491 * The build dependency for librrd has been removed. Binaries built
3492 without librrd are client-only and will multicast their value as
3493 with the `-c' argument.
3494 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3495 * The newly introduced `-f' switch prevents daemon initialization
3496 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3497 Barcellos for this patch.
3499 2005-11-04, Version 3.3.0 (Revision 216)
3500 * New modules have been added:
3501 - `serial', for monitoring traffic on the serial interfaces
3502 - `nfs', for graphing NFS procedure calls
3503 - `tape', traffic from/to tape devices
3504 * The memory.rrd now accepts more than 4Gig of memory.
3506 2005-10-26, Version 3.2.0 (Revision 200)
3507 * Support for graphing the processes has been added (thanks to Lyonel
3509 * If reading from hddtemp fails collectd will increase the time
3510 between polls up to one day.
3511 * The init.d files have been improved.
3512 * Problems with the spec file have been fixed.
3514 2005-10-16, Version 3.1.0 (Revision 194)
3515 * Added the `setsid' syscall to the startup code.
3516 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3518 2005-09-30, Version 3.0.0 (Revision 184)
3519 * The ability to send/receive data to/from the network (think
3520 multicast) has been added.
3521 * Modules have been split up into shared libraries can be loaded at
3522 runtime. The biggest advantage is that the core program doesn't need
3523 to be linked against an external library.
3524 * A patch by George Kargiotakis has been applied: It fixes the sensors
3525 behaviour then more than one sensor is being queried.
3527 2005-09-16, Version 2.1.0 (Revision 172)
3528 * A module for swap statistics has been added.
3530 2005-09-09, Version 2.0.0 (Revision 135)
3531 * Filenames can no longer be configured at program startup. The only
3532 options as of this version are the directory and ping hosts.
3533 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3534 Soft-IRQ statistics are added to `System'.
3535 * Diskstats now collect read and write bytes, not sectors.
3536 * Ping statistics can now be collected for more than one host. There
3537 is no default any more: If no host is given no host will be pinged.
3538 * A self-written patch for libping has been applied so it builds
3541 2005-09-01, Version 1.8.1 (Revision 123)
3542 * Much improved configure-script: libraries and features may now be
3544 * More detailed warnings/error messages when RRD update fails.
3546 2005-08-29, Version 1.8.0:
3547 * Support for collecting disk statistics under Solaris.
3549 2005-08-25, Version 1.7.0:
3550 * Support for libstatgrab[1] for load, memory usage and network
3551 traffic. CPU- and disk-usage are not (yet) supported, since
3552 libstatgrab returns insufficient information. I will contact the
3554 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3555 aren't necessarily counted linear which is now handled correctly.
3556 [1]: http://www.i-scream.org/libstatgrab/
3558 2005-08-21, Version 1.6.0:
3559 * Basic support for Solaris: System load and cpu-usage can be
3560 collected under Solaris, too. Other stats will follow later.
3561 * Many fixes in the autoconf-script
3562 * Collection/Museum scripts have been added under contrib/museum
3563 * collectd may now be started in unprivileged mode, though ping
3564 statistics will not work.
3566 2005-07-17, Version 1.5.1:
3567 * Diskstats-RRDs now use major/minor for naming. Some systems have
3568 weird strings as disk-names..
3570 2005-07-17, Version 1.5:
3571 * A new module, diskstats, has been added. It collects information
3572 about the disks and partitions.
3574 2005-07-11, Version 1.4.2:
3575 * The meminfo module has been changed to work with more platforms
3576 and/or kernel versions.
3578 2005-07-10, Version 1.4.1: Correct traffic stats
3579 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3580 forgot to correct when I changed that module.
3582 2005-07-09, Version 1.4: More traffic stats
3583 * Traffic is now collected for all interfaces that can be found
3584 * Temperature-statistics are read from lm-sensors if available
3586 2005-07-08, Version 1.3: CPU stats
3587 * Collecting CPU statistics now
3589 2005-07-12, Version 1.2: Using syslog
3590 * collectd is now using the syslog facility to report errors, warnings
3592 * The default directory is now /var/db/collectd
3594 2005-07-10, Version 1.1: Minor changes
3595 * Nothing really useful to say ;)
3597 2005-07-09, Version 1.0: Initial Version
3598 * The following modules are provided:
