1802 added to the Linux implementation. Thanks to Darrell Bishop for his
1803 patch.

2318 code. Thanks to Sebastian Harl for the patch.
2319 * collectd: Remove old values when a cache entry is marked as missing.

2322 Díaz for the patch.
2323 * collectd: The “plugin_unregister_read” function has been fixed.
2324 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library

2364 first one prevented thresholds to be checked at all, the second one
2365 caused wrong behavior with the persistency option. Thanks to Andrés
2366 J. Díaz for fixing these problems.
2367 * collectd: Handling of the `Include' configuration option has been
2368 fixed.
2369 * rrdtool plugin: Make sure initialization is run only once. This

2371 Thanks to Amit Gupta for reporting this bug.
2372 * java plugin: Make it possible to use dots ('.') instead of slashes
2373 ('/') as the class separator. Thanks to Randy Rizun for pointing

2481 name which prevented this match to be used as documented. Thanks to
2482 Bruno Prémont for finding this problem.
2483 * bind plugin: Fix collection of the cached RR sets. The number of RR
2484 sets currently in the cache was collected as a counter value, which
2485 is nonsense. Thanks to Bruno Prémont for implementing this.

2527 Kuhnle for the patch.
2528 * csv plugin: Make it possible to write values to STDOUT instead of
2529 files. This is meant for testing purposes mostly. The output written
2530 to STDOUT is compatible with the exec plugin. Thanks to Doug
2531 MacEachern for the patch.
2532 * curl plugin: This new plugin can be used to read web pages and parse
2533 them using the same mechanism that's used in the tail plugin.
2534 * dbi plugin: This new plugin allows you to connect to a variety of
2535 relational databases and use SQL to gather custom statistics from
2536 it. It is similar to the already existing PostgreSQL plugin but uses
2537 libdbi to communicate with the database(s).
2538 * interface plugin: Use the ignorelist framework when selecting /
2539 ignoring interfaces. This allows one to use regular expressions to
2540 select interfaces, too.

2557 * perl plugin: Added support for `notification meta data'.
2558 * perl plugin: Added support for the `filter chain' infrastructure by
2559 allowing plugins to register `matches' and `targets'.
2560 * postgresql plugin: The preferred configuration syntax has been
2561 updated to be in line with the syntax used by the new dbi and oracle
2562 plugins. The compatibility code for the old syntax is present.
2563 Support for the new `Result' blocks and the interval parameter has
2564 been added.
2565 * processes plugin: Stacksize and virtual memory usage statistics have
2566 been added. Portability fixes.
2567 * rrdcached plugin: This new plugin uses the (still in development)
2568 RRD accelerator daemon, rrdcached. This daemon works very similar to
2569 the original rrdtool plugin of collectd, but adds some more nice
2570 features.
2571 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2572 added.
2574 2009-05-09, Version 4.5.4
2575 * Build system, various plugins: Many build fixes for FreeBSD,
2576 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2577 for many fixes and providing a build system for many platforms,
2578 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2579 providing an OpenBSD system.
2580 * collectd: Fix a potential race condition when creating directories.
2581 * battery plugin: Don't complain about a missing directory every
2582 interval.
2583 * dns plugin: Slight portability fixes.
2584 * exec plugin: Allow executed programs to close STDERR. Thanks to
2585 Thorsten von Eicken for reporting this problem.
2586 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2587 Tomasz Pala for the patch.
2588 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2589 the patch.
2590 * rrdtool plugin: Fix a possible race condition: If the network plugin
2591 is initialized and dispatches a value before the rrdtool plugin is
2592 initialized, the daemon may crash.
2593 * memory plugin: Fix a potential problem under Solaris.
2595 2009-02-22, Version 4.5.3
2596 * build system: The check for libupsclient even when `pkg-config' is
2597 not available.
2598 * collectd: Fix error handling in the global cache.
2599 * Collectd::Unixsock: Error handling has been improved.
2600 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
2601 patch.
2602 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2603 faults. Thanks to Peter Holik for his patch.
2604 * tcpconns plugin: An endianness problem has been fixed in the *BSD
2605 code. Thanks to "thated" for reporting this.
2607 2009-01-02, Version 4.5.2
2608 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2609 file may be in both locations, especially when the database was
2610 installed in a non-standard path. Thanks to Dusty Doris for
2611 reporting this.
2612 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2613 Solaris, in the configure script automatically.
2614 * build system, tcpconns plugin: Check for `kvm_nlist' and
2615 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2616 library with similar functions to the BSD variant, but doesn't
2617 provide these necessary functions.
2618 * collectd.conf(5): Various fixes and clarifications.
2619 * collectd: Remove a GNUism (unnamed unions), thus improving
2620 portability.
2621 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2622 This solves portability problems, especially for Solaris.
2623 * dns plugin: Fix a portability problem with NetBSD.
2624 * filecount plugin: Fix an off-by-one error. This error may cause a
2625 segmentation fault.
2626 * network plugin: Fix the handling of `type' in the network protocol.
2627 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2628 much larger buffer. This caused the `type' to be transferred much
2629 more often than necessary. In some cases, e. g. the `cpu' and
2630 `cpufreq' plugins being used at the same time, data may be corrupted
2631 in those files. Thanks to Bruno Prémont for debugging and reporting
2632 this issue.
2633 * processes plugin: Fix a possible segmentation fault when specifying
2634 invalid configuration options.
2635 * unixsock plugin: Make sure the initialization function is run only
2636 once. This resolves a file descriptor leak under systems which run
2637 the initialization more than once, such as Solaris.
2639 2008-10-16, Version 4.5.1
2640 * build system: Change `--enable-<plugin>' to abort with an error if
2641 dependencies are not met. Thanks to Bruno Prémont for the patch.
2642 Also, the poisoning of various string functions has been restricted
2643 to debug builds.
2644 * collectd: Fix a memory leak in the global value cache. With every
2645 *missing* value a couple of bytes would be leaked. Another memory
2646 leak in the configuration handling code has been fixed. Thanks to
2647 Niraj Tolia for reporting these issues.
2648 * collectd: Fix an off-by-one error in the ignorelist functionality.
2649 When using regular expressions, the last character would be missing,
2650 possibly matching differently from what one would expect.
2651 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2652 problem.
2653 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2654 Linzberger for reporting the bug.
2655 * iptables plugin: Fix an off-by-one error. If a string was just one
2656 character too long, it was truncated instead of reporting an error.
2657 * network plugin: Fix a memory leak in the configuration handling
2658 code. Thanks to Niraj Tolia for reporting this issue.
2659 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2660 * postgresql plugin: Don't reopen connection during reinitialization.
2661 This fixes a bug under Solaris and potentially other platforms.
2662 Missing calls to `PQclear' have been added, too. This fixes memory
2663 leaks. Thanks to ``Admin'' for reporting these bugs.
2664 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2665 library.
2666 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2667 problems with some `libc's. Thanks to Matthias Lay for reporting the
2668 bug.
2670 2008-09-04, Version 4.5.0
2671 * collectd: Added the ability to flush certain identifiers.
2672 * collectd: The concept of `notification meta data' has been
2673 introduced.
2674 * filecount plugin: The new filecount plugin counts the number of
2675 files in a directory and its subdirectories.
2676 * ipmi plugin: Sensor names have been changed to ensure unique names.
2677 Notifications upon added and removed sensors can now be generated.
2678 * notify_desktop plugin: This new plugin sends notifications to the
2679 X desktop using the structure defined in the `Desktop Notification
2680 Specification'.
2681 * notify_email plugin: This new plugin sends out notifications via
2682 email, using the `esmtp' library.
2683 * onewire plugin: The new experimental(!) onewire plugin reads values,
2684 such as temperatures, from sensors connected to the computer via the
2685 onewire bus.
2686 * perl plugin: Improved synchronized access to internal data structures
2687 and fixed a possible dead-lock.
2688 * perl plugin: Added the ability to flush certain identifiers and marked
2689 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2690 plugin_flush().
2691 * perl plugin: Added the ability to configure Perl plugins.
2692 * postgresql plugin: The new postgresql plugin collects statistics
2693 about or from a PostgreSQL database.
2694 * processes plugin: The `ProcessMatch' option has been added.
2695 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2696 IO load.
2697 * tcpconns plugin: This plugin has been ported to OpenBSD.
2698 * thermal plugin: The new thermal plugin collects system temperatures
2699 using Linux ACPI thermal zone data.
2701 2009-01-02, Version 4.4.5
2702 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2703 file may be in both locations, especially when the database was
2704 installed in a non-standard path. Thanks to Dusty Doris for
2705 reporting this.
2706 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2707 Solaris, in the configure script automatically.
2708 * collectd.conf(5): Various fixes and clarifications.
2709 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2710 portability problems, especially for Solaris.
2711 * dns plugin: Fix a portability problem with NetBSD.
2712 * network plugin: Fix the handling of `type' in the network protocol.
2713 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2714 much larger buffer. This caused the `type' to be transferred much
2715 more often than necessary. In some cases, e. g. the `cpu' and
2716 `cpufreq' plugins being used at the same time, data may be corrupted
2717 in those files. Thanks to Bruno Prémont for debugging and reporting
2718 this issue.
2719 * unixsock plugin: Make sure the initialization function is run only
2720 once. This resolves a file descriptor leak under systems which run
2721 the initialization more than once, such as Solaris.
2723 2008-10-16, Version 4.4.4
2724 * build system: Change `--enable-<plugin>' to abort with an error if
2725 dependencies are not met. Thanks to Bruno Prémont for the patch.
2726 Also, the poisoning of various string functions has been restricted
2727 to debug builds.
2728 * collectd: Fix a memory leak in the global value cache. With every
2729 *missing* value a couple of bytes would be leaked. Another memory
2730 leak in the configuration handling code has been fixed. Thanks to
2731 Niraj Tolia for reporting these issues.
2732 * collectd: Fix an off-by-one error in the ignorelist functionality.
2733 When using regular expressions, the last character would be missing,
2734 possibly matching differently from what one would expect.
2735 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2736 problem.
2737 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2738 Linzberger for reporting the bug.
2739 * network plugin: Fix a memory leak in the configuration handling
2740 code. Thanks to Niraj Tolia for reporting this issue.
2741 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2742 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2743 problems with some `libc's. Thanks to Matthias Lay for reporting the
2744 bug.
2746 2008-09-01, Version 4.4.3
2747 * collectd: Fix a memory leak in the threshold checking code.
2748 * memcached plugin: Fix a too short timeout and a related file
2749 descriptor leak.
2750 * memory plugin: A typo in the libstatgrab code has been fixed.
2751 * snmp plugin: Fix a possible memory leak.
2753 2008-07-15, Version 4.4.2
2754 * build system: Use pkg-config to detect the upsclient library.
2755 * collectd: Try even harder to determine the endianness of the
2756 architecture collectd is being built on.
2757 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2758 of disks.
2759 * dns plugin: Fix compilation errors with BIND versions 19991001
2760 through 19991005.
2761 * network plugin: Bugfix in the init routine: The init function
2762 cleared a buffer regardless of its contents. This could lead to lost
2763 values under Solaris.
2764 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2765 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2766 function.
2767 * wireless plugin: Work around incorrect noise and power values
2768 returned by some broken drivers.
2770 2008-06-03, Version 4.4.1
2771 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2772 to kyrone for reporting this.
2773 * collectd: Fixed min/max output in notifications generated by
2774 threshold checking.
2775 * collectd-nagios: Fix the protocol used to communicate with the
2776 daemon.
2777 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2778 initialization has errors. An issue with Perl 5.10 has been fixed.
2779 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2780 René Rebe and Siegmund Gorr for reporting this.
2782 2008-05-06, Version 4.4.0
2783 * collectd: Internal code cleanups.
2784 * collectd: Added support for a `Flush' command in the unixsock and
2785 exec plugins. This command can be used to force a plugin (or all) to
2786 flush its values to disk.
2787 * collectd: Thresholds can now be configured to apply to one data
2788 source only, making it possible to configure different thresholds
2789 for each data source.
2790 * apache, nginx plugins: Added the possibility to disable host and/or
2791 peer verification.
2792 * ascent plugin: The new ascent plugin reads and parses the statistics
2793 page of an Ascent server.
2794 * cpu plugin: Support for the statgrab library has been added.
2795 * disk plugin: The possibility to ignore certain disks or collect only
2796 specific disks has been added.
2797 * disk plugin: Support for the statgrab library has been added.
2798 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
2799 sensor values via IPMI, the intelligent platform management
2800 interface.
2801 * iptables plugin: The iptc library that is used by the iptables
2802 plugin has been added to the distribution, because it is not
2803 provided by all distributions and removed from at least one.
2804 * powerdns plugin: The new powerdns plugin reads statistics from an
2805 authoritative or a recursing PowerDNS name server.
2806 * rrdtool plugin: The size of the files generated with the default
2807 configuration has been decreased.
2808 * tail plugin: The new tail plugin can be used to gather statistics by
2809 continuously reading from log files.
2810 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2811 TeamSpeak2 server and collects statistics about the number of users
2812 and number of channels.
2813 * users plugin: Support for the statgrab library has been added.
2814 * vmem plugin: The new vmem plugin collects very detailed statistics
2815 about the virtual memory subsystem of Linux.
2817 2008-08-30, Version 4.3.4
2818 * Build system: Improved detection of and linking with the statgrab
2819 library.
2820 * collectd: Portability fixes, especially to determine endianness more
2821 reliable.
2822 * Various plugins: Fix format strings.
2823 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2824 again has been applied.
2825 * memcached plugin: Fix a too short timeout and a related file
2826 descriptor leak.
2827 * memory plugin: A typo in the libstatgrab code has been fixed.
2828 * network plugin: A fix in the initialization function solves problems
2829 under Solaris.
2830 * nginx plugin: A thread-unsafe function has been replaced.
2831 * vserver plugin: A thread-unsafe function has been replaced.
2832 * wireless plugin: A work-around for broken wireless drivers has been
2833 added.
2835 2008-04-22, Version 4.3.3
2836 * build system: Improved detection of several libraries, especially if
2837 they are in non-standard paths.
2838 * build system: Portability fixes: Automatically define "_REENTRANT"
2839 if the libc expects it.
2840 * collectd: Error and warning messages have been improved.
2841 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2842 using them.
2843 * apache plugin: Allocate new memory when reading a webpage instead of
2844 using a buffer of static size.
2845 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2846 the program.
2847 * hddtemp plugin: Error and warning messages have been improved.
2848 * sensors plugin: Fix sensor collection for some chip types.
2850 2008-03-29, Version 4.3.2
2851 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2852 `Persist' threshold options.
2853 * collectd: Fix handling of missing values in the global value cache.
2854 * collectd: Improved error messages when parsing the configuration.
2855 * sensors plugin: Fix temperature collection with libsensors4.
2856 * unixsock plugin: Fix mixed input and output operation on streams.
2857 * wireless plugin: Fix reading noise value.
2859 2008-03-05, Version 4.3.1
2860 * exec plugin: Set supplementary group IDs.
2861 * network plugin:
2862 + Use `memcpy' when constructing/parsing a package to avoid
2863 alignment problems on weird architectures, such as Sparc.
2864 + Translate doubles to/from the x86 byte representation to ensure
2865 cross-platform compatibility.
2866 * ping plugin: Correct the handling of the `TTL' setting.
2867 * swap plugin: Reapply a patch for Solaris.
2868 * tcpconns plugin: Portability improvements.
2870 2008-02-18, Version 4.3.0
2871 * collectd: Notifications have been added to the daemon. Notifications
2872 are status messages that may be associated with a data instance.
2873 * collectd: Threshold checking has been added to the daemon. This
2874 means that you can configure threshold values for each data
2875 instance. If this threshold is exceeded a notification will be
2876 created.
2877 * collectd: The new `FQDNLookup' option tells the daemon to use the
2878 full qualified domain name as the hostname, not just the host part
2879 es returned by `gethostname(2)'.
2880 * collectd: Support for more than one `TypesDB' file has been added.
2881 This is useful when one such file is included in a package but one
2882 wants to add custom type definitions.
2883 * collectd: The `Include' config option has been expanded to handle
2884 entire directories and shell wildcards.
2885 * collectdmon: The new `collectdmon' binary detects when collectd
2886 terminates and automatically restarts it again.
2887 * csv plugin: The CSV plugin is now able to store counter values as a
2888 rate, using the `StoreRates' configuration option.
2889 * exec plugin: Handling of notifications has been added and the
2890 ability to pass arguments to the executed programs has been added.
2891 * hddtemp plugin: The new `TranslateDevicename' option lets you
2892 disable the translation from device names to major-minor-numbers.
2893 * logfile plugin: Handling of notifications has been added.
2894 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2895 domain name lookups in this plugin.
2896 * perl plugin: Many internal changes added support for handling multiple
2897 threads making the plugin reasonably usable inside collectd. The API has
2898 been extended to support notifications and export global variables to
2899 Perl plugins; callbacks now have to be identified by name rather than a
2900 pointer to a subroutine. The plugin is no longer experimental.
2901 * uuid plugin: The new UUID plugin sets the hostname to an unique
2902 identifier for this host. This is meant for setups where each client
2903 may migrate to another physical host, possibly going through one or
2904 more name changes in the process. Thanks to Richard Jones from
2905 Red Hat's Emerging Technology group for this plugin.
2906 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2907 CPU, disk and network statistics about guest systems on the same
2908 physical server. Thanks to Richard Jones from Red Hat's Emerging
2909 Technology group for this plugin.
2911 2008-04-22, Version 4.2.7
2912 * build system: Improved detection of several libraries, especially if
2913 they are in non-standard paths.
2914 * build system: Portability fixes: Automatically define "_REENTRANT"
2915 if the libc expects it.
2916 * collectd: Error and warning messages have been improved.
2917 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2918 using them.
2919 * apache plugin: Allocate new memory when reading a webpage instead of
2920 using a buffer of static size.
2921 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2922 the program.
2923 * hddtemp plugin: Error and warning messages have been improved.
2924 * sensors plugin: Fix sensor collection for some chip types.
2926 2008-03-29, Version 4.2.6
2927 * collectd: Improved error messages when parsing the configuration.
2928 * sensors plugin: Fix temperature collection with libsensors4.
2929 * unixsock plugin: Fix mixed input and output operation on streams.
2930 * wireless plugin: Fix reading noise value.
2932 2008-03-04, Version 4.2.5
2933 * apache plugin: Improved initialization and error messages.
2934 * exec plugin: Set supplementary group IDs.
2935 * network plugin:
2936 + Create separate threads for reading from the socket and parsing
2937 and dispatching incoming packets. Versions prior to this may have
2938 problems in high-load situations, where the socket receive buffers
2939 overflows, resulting in gaps in the data.
2940 + Use `memcpy' when constructing/parsing a package to avoid
2941 alignment problems on weird architectures, such as Sparc.
2942 + Translate doubles to/from the x86 byte representation to ensure
2943 cross-platform compatibility.
2944 * ping plugin: Correct the handling of the `TTL' setting.
2945 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2946 * swap plugin: Reapply a patch for Solaris.
2947 * tcpconns plugin: Portability improvements.
2949 2008-01-21, Version 4.2.4
2950 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2951 the permission on the socket as documented in the manpage. Thanks to
2952 Evgeny Chukreev for fixing this issue.
2953 * collectd: The documentation has been improved.
2955 2007-12-28, Version 4.2.3
2956 * sensors plugin: Updated the plugin to build and work with version 3
2957 of the libsensors library.
2959 2007-12-15, Version 4.2.2
2960 * nginx plugin: Incorrect comparison of strings lead to a segfault
2961 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2962 this.
2963 * logfile plugin: The config option `Timestamp' was handled
2964 incorrectly and basically always active. Thanks to Luke Heberling
2965 for fixing this.
2967 2007-11-08, Version 4.2.1
2968 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2969 enabled on the host.
2970 * snmp plugin: Fix a memory leak.
2972 2007-10-27, Version 4.2.0
2973 * collectd: The new config option `Include' lets you include other
2974 configfiles and thus split up your config into smaller parts. This
2975 may be especially interesting for the snmp plugin to keep the data
2976 definitions separate from the host definitions.
2977 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2978 (number of connections, octets and packets for each service and
2979 destination). Thanks to Sebastian Harl for this plugin.
2980 * memcached plugin: The new `memcached' plugin connects to a memcached
2981 daemon process and collects statistics of this distributed caching
2982 system. Thanks to Antony Dovgal for contributing this plugin.
2983 * nginx plugin: The new `nginx' plugin reads the status page of an
2984 nginx daemon and saves the handled connections and requests.
2985 * perl plugin: Many changes, including the added `EnableDebugger'
2986 config option which lets you debug your Perl plugins more easily.
2987 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2988 be more thread-safe otherwise by locking calls to the library.
2989 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2990 correct the values returned by SNMP-agents. If a <data> block is
2991 defined as `table' the instance is now optional. The sequence number
2992 is used as the type-instance in this case. The new `InstancePrefix'
2993 option allows to add arbitrary prefixes to the type-instance.
2994 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2995 certain TCP connections and what state they're in. This can be used
2996 to see how many connections your FTP server has to handle or how
2997 many outgoing connections your mailserver has open.
2999 2008-01-11, Version 4.1.6
3000 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3001 the permission on the socket as documented in the manpage. Thanks to
3002 Evgeny Chukreev for fixing this issue.
3003 * collectd: The documentation has been improved.
3005 2007-12-27, Version 4.1.5
3006 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3007 memory situations.
3008 * sensors plugin: Updated the plugin to build and work with version 3
3009 of the libsensors library.
3011 2007-11-08, Version 4.1.4
3012 * Build system: Improve detection of the rrd library, especially if
3013 it's in a non-standard location.
3014 * Build system: A bug when parsing the argument for
3015 `--with-libnetsnmp' has been fixed.
3016 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3017 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3018 a deadlock or delay when shutting down the daemon.
3019 * snmp plugin: Fix a memory leak.
3021 2007-10-24, Version 4.1.3
3022 * collectd: A build issue under Solaris has been resolved by renaming
3023 data types.
3024 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3025 be more thread-safe otherwise by locking calls to the library.
3027 2007-09-28, Version 4.1.2
3028 * apcups plugin: Fix reporting of the `load percent' data.
3029 * wireless plugin: Correct the handling of cards returning signal and
3030 noise quality as percentage.
3031 * perl plugin: Fix a possible buffer overflow in get_module_name().
3032 * build system: Further improve the detection of libraries.
3033 * netlink plugin: Build issues under some older versions of the Linux
3034 includes (i. e. Debian Sarge) have been fixed.
3035 * snmp plugin: Fix a potential segfault when a host times out. Add
3036 support for the `timeticks' type.
3038 2007-09-12, Version 4.1.1
3039 * Build system: The detection of `libnetlink' has been improved.
3040 * collectd: The documentation has been fixed in numerous places.
3041 * exec plugin: Setting the group under which to run a program has been
3042 fixed.
3043 * collectd: The `sstrerror' function was improved to work correctly
3044 with the broken GNU version of `strerror_r'.
3045 * collectd: Write an error message to STDERR when loading of a plugin
3046 fails.
3047 * apcups plugin: Fix the `types' used to submit the values: They still
3048 has an `apcups_' prefix which doesn't work anymore.
3049 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3050 whatever the client thinks is `now'..
3052 2007-09-01, Version 4.1.0
3053 * Build system: The build system has been changed to automatically
3054 disable all plugins, which are missing dependencies. The dependency
3055 checking has been removed from the plugins themselves to remove
3056 redundancy.
3057 * Flexible interval: The interval of collected data is now sent along
3058 with the data itself over the network, so that the interval-settings
3059 of server and clients no longer needs to match.
3060 * netlink plugin: The new `netlink' plugin connects to the Linux
3061 kernel using a netlink socket and uses it to query information about
3062 interfaces, qdiscs and classes.
3063 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3064 to not block data collection.
3065 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3066 network devices, such as switches, routers, thermometers, rack
3067 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3068 plugin.
3069 * unixsock plugin: Added the `LISTVAL' command.
3070 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3071 of music played with xmms.
3073 2007-09-28, Version 4.0.9
3074 * apcups plugin: Fix reporting of the `load percent' data.
3075 * wireless plugin: Correct the handling of cards returning signal and
3076 noise quality as percentage.
3077 * perl plugin: Fix a possible buffer overflow in get_module_name().
3079 2007-09-12, Version 4.0.8
3080 * collectd: The `sstrerror' function was improved to work correctly
3081 with the broken GNU version of `strerror_r'.
3082 * collectd: Write an error message to STDERR when loading of a plugin
3083 fails.
3084 * apcups plugin: Fix the `types' used to submit the values: They still
3085 has an `apcups_' prefix which doesn't work anymore.
3086 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3087 whatever the client thinks is `now'..
3089 2007-08-26, Version 4.0.7
3090 * documentation: Some typos have been fixed and some information has
3091 been improved.
3092 * build system: Many fixes for detecting libraries in unusual places,
3093 such as on RedHat systems. The affected libraries are `libcurl',
3094 `libmysql', and `libupsclient'.
3095 * network plugin: Allow the `Port' option to be specified as a number
3096 (i. e. without quotes).
3097 * nut plugin: A fix allows linking the nut plugin against
3098 libupsclient, version >= 2.2.0.
3099 * processes plugin: Fix a potential segmentation fault.
3101 2007-07-30, Version 4.0.6
3102 * sensors plugin: Fix the ignorelist functionality: Only the `type
3103 instance' was used to match against the list, but the documentation
3104 told otherwise. This release fixes the code, so it complies with the
3105 documentation.
3106 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3107 configuration messages will end up in the logging facility.
3108 * conrtib/fedora: The contributed specfile for Fedora has been
3109 updated.
3111 2007-07-05, Version 4.0.5
3112 * Portability: More fixes for OpenBSD have been included.
3114 2007-06-24, Version 4.0.4
3115 * cpu plugin: Fixed the Solaris code.
3116 * dns plugin: Fixed a build issue for OpenBSD.
3117 * interface plugin: Fixed the Solaris code.
3118 * load plugin: Fixed the alternative `/proc' Linux code.
3119 * memory plugin: Fixed the Solaris code.
3120 * oconfig: Don't require `-lfl' anymore.
3122 2007-06-19, Version 4.0.3
3123 * cpu plugin: Fix the Darwin / Mac OS X code.
3124 * ping plugin: Use the return value of `getpid', not its address.
3125 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3126 initialized correctly.
3127 * configure: Added `--with-nan-emulation' to aid cross compilation.
3129 2007-06-12, Version 4.0.2
3130 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3131 they're given in numerically form.
3133 2007-06-07, Version 4.0.1
3134 * iptables plugin: A bug in the configuration routine has been fixed.
3135 Setting a comment in the configfile will no longer cause a
3136 segmentation fault.
3138 2007-06-03, Version 4.0.0
3139 * collectd: The plugin-infrastructure has been changed to allow for
3140 more types of plugins, namely `write' and `log' plugins.
3141 * collectd: The read-function has been changed to read many plugins in
3142 parallel, using threads. Thus, plugins generally need to use
3143 thread-safe functions from now on.
3144 * collectd: The '-t' command line options allows to perform syntax tests
3145 of the configuration file and exit immediately.
3146 * csv plugin: The new `csv' plugin handles output to `comma separated
3147 values'-files.
3148 * rrdtool plugin: The new `rrdtool' plugin handles output to
3149 RRD-files. Data can be cached to combine multiple updates into one
3150 write to increase IO-performance.
3151 * network plugin: The new `network' plugin handles IO via the network.
3152 It implements a different, much more extensible protocol which can
3153 combine many values in one packet, decreasing the number of UDP-
3154 packets being sent. It can read from and send to the network and
3155 with the appropriate configuration even forward packets to other
3156 networks.
3157 * unixsock plugin: The new `unixsock' plugin provides an interface to
3158 communicate with the daemon while it is running. Right now the
3159 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3160 come.
3161 * perl plugin: The new `perl' plugin allows you to write extensions
3162 for collectd in the scripting-language Perl.
3163 * logfile plugin: The new `logfile' plugin writes logmessages to files
3164 or STDOUT or STDERR.
3165 * syslog plugin: The new `syslog' plugin sends logmessages to the
3166 system's syslog daemon.
3167 * entropy plugin: The new `entropy' plugin collects the amount of
3168 entropy currently being available to the system.
3169 * exec plugin: The new `exec' plugin forks child processes and reads
3170 back values provided by the forked processes.
3171 * iptables plugin: The new `iptables' plugin reads counters from
3172 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3173 plugin.
3174 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3175 to Peter Holik for contributing this plugin.
3176 * nut plugin: The new `nut' plugin connects the upsd of the `network
3177 ups tools' and reads information about the connected UPS.
3178 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3179 connections) field was added by Florent Monbillard.
3180 * collectd-nagios: The new `collectd-nagios' binary queries values
3181 from collectd, parses them and exits according to Nagios-standards.
3182 * manpages: The manpages have been improved a lot.
3184 2007-09-28, Version 3.11.7
3185 * wireless plugin: Correct the handling of cards returning signal and
3186 noise quality as percentage.
3188 2007-08-31, Version 3.11.6
3189 * processes plugin: Fix a potential segmentation fault.
3191 2007-05-29, Version 3.11.5
3192 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3193 * ntpd plugin: Fix a potential buffer overflow.
3194 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3195 were accounted as `zombies'.
3197 2007-04-10, Version 3.11.4
3198 * dns plugin: Change the order of includes to make the plugin compile
3199 under FreeBSD.
3201 2007-03-30, Version 3.11.3
3202 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3203 of the unused `COLLECT_KSTAT'.
3205 2007-02-11, Version 3.11.2
3206 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3207 NULL-pointer may have been passed to `printf' which causes a
3208 segfault with some libcs.
3210 2007-02-10, Version 3.11.1
3211 * df plugin: Some wrong defines have been fixed so the plugin works
3212 under Solaris again.
3213 * dns plugin: The usage of a struct has been fixed to work with
3214 non-GNU libcs.
3215 * processes plugin: Some missing defines have been added so the plugin
3216 compiles cleanly under FreeBSD and presumably other UNIXes.
3218 2006-12-22, Version 3.11.0
3219 * collectd: The new command line option `-P' makes it easier for
3220 distributors to change the location of PID-files.
3221 * collectd: The daemon shuts down faster now which makes it easier to
3222 write init.d-scripts for it.
3223 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3224 caused problems every now and then.
3225 * df plugin: New config options allow to ignore certain mountpoints,
3226 filesystem types or devices.
3227 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3228 and interprets it. It collects traffic as well as qtype, opcode and
3229 rcode counts.
3230 * email plugin: Sebastian Harl has contributed this plugin which
3231 counts received mails in categories (e. g. ham, spam, virus), spam
3232 score (as given by SpamAssassin) and check types.
3233 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3234 uses `mbmon' to gather information from sensors on the motherboard.
3235 * processes plugin: Collect detailed statistics for configured
3236 processes, that's process and thread count, CPU usage, resident
3237 segment size and pagefaults.
3238 * multimeter plugin: Peter Holik contributed a new plugin which
3239 queries multimeters.
3240 * sensors plugin: Lubos Stanek has put much effort into improving this
3241 plugin, including `extended naming', collection of voltage values
3242 and the possibility to ignore certain values.
3244 2006-12-21, Version 3.10.4
3245 * Max Kellermann has identified a bug in the server routine: When
3246 opening a socket fails the daemon will (re)try opening the socket in
3247 an endless loop, ultimately leading to a `EMFILE' error.
3249 2006-11-04, Version 3.10.3
3250 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3251 ntpd's reply was sent in more than one packet, the buffer size was
3252 calculated incorrectly, resulting in the reading of uninitialized or
3253 freed memory.
3255 2006-11-01, Version 3.10.2
3256 * The sample config file has been improved.
3257 * Errors in the manpages have been corrected.
3258 * The ping-plugin now adds hosts during initialization, not during
3259 startup. This speeds up startup when no network connectivity is
3260 available. Also, the hosts are being added later when the network is
3261 available.
3262 * Improved BSD-support for the df-plugin.
3263 * Fixed syntax errors in the swap-plugin for Mac OS X.
3264 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3265 plugin.
3266 * Don't disable the mysql-plugin if connecting to the database fails
3267 during initialization. Instead, try again in increasing intervals.
3269 2006-07-19, Version 3.10.1
3270 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3271 the apcups cannot be reached, unconnected sockets will pile up and
3272 eventually lead to `Too many open files' errors.
3274 2006-07-09, Version 3.10.0
3275 * The `disk' plugin has been ported to Darwin.
3276 * The `battery' plugin should work on many Apple computers now.
3277 * The `traffic' plugin can now ignore certain interfaces. Also,
3278 statistics for sent/received packets and errors have been added.
3279 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3280 to Anthony Gialluca for contributing this plugin and providing me
3281 with a test environment :)
3282 * A plugin for monitoring an NTP instance and the local clock drift
3283 has been added.
3285 2006-06-25, Version 3.9.4
3286 * The Solaris code in the `swap' plugin has been changed to reflect
3287 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3288 working this out.
3289 * The debugging system has been fixed to work with the Sun libc.
3290 * When built without librrd the variable `operating_mode' could be
3291 uninitialized. Thanks to David Elliot for reporting the bug.
3293 2006-06-01, Version 3.9.3
3294 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3295 operating systems also profit from the changes, but I wasn't able to
3296 check that.
3297 * Changed the build system to find the netinet-includes under FreeBSD
3298 and therefore successfully build the `liboping' library there.
3300 2006-05-09, Version 3.9.2
3301 * Applied a patch to the `liboping' library. Due to a bug in the
3302 sequence checking the `ping' plugin stopped working after
3303 approximately 7.6 days.
3305 2006-05-09, Version 3.8.5
3306 * Applied a patch to the `liboping' library. Due to a bug in the
3307 sequence checking the `ping' plugin stopped working after
3308 approximately 7.6 days.
3310 2006-04-21, Version 3.9.1
3311 * Build issues with Solaris and possible other architectures have been
3312 resolved.
3313 * Problems when building the `apache'-plugin without `libcurl' have
3314 been resolved.
3315 * A bug in the `ping' plugin has been fixed. Sorry folks.
3317 2006-04-02, Version 3.9.0
3318 * A plugin to monitor the Apache webserver has been added.
3319 <http://httpd.apache.org/>
3320 * A plugin to collect statistics about virtual servers using VServer.
3321 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3322 this plugin :)
3323 * A plugin for wireless LAN cards has been added. It monitors signal
3324 strength, link quality and noise ratio..
3325 * A plugin for Apple hardware sensors has been added.
3326 * An option to compile collectd with different `step' and `heartbeat'
3327 settings has been added. The size of RRAs is no longer static but
3328 calculated based on the settings for `step' and `width'.
3329 * The `ping' plugin can now be configured to use a certain TTL.
3330 * A plugin to monitor the hardware sensors of Apple computers has been
3331 added.
3332 * The plugins `cpu', `memory', `processes' and `traffic' have been
3333 ported to Mach/Darwin (Mac OS X).
3334 * The `log mode' has been contributed by Christophe Kalt. It writes
3335 the data into text files rather than RRD files.
3337 2006-04-09, Version 3.8.4
3338 * Applied patch by Vincent Stehlé which improves the disk-name
3339 resolution in the `hddtemp' plugin for Linux systems.
3341 2006-04-02, Version 3.8.3
3342 * Applied a patch by James Byers: The MySQL plugin was not working
3343 with MySQL 5.0.2 or later.
3345 2006-03-14, Version 3.8.2
3346 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3347 the GNU libc, because it points to `/etc/fstab' rather than
3348 `/etc/mtab'.
3350 2006-03-13, Version 3.8.1
3351 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3352 * Fixes in the debian `postinst' and `init.d' scripts.
3354 2006-03-09, Version 3.8.0
3355 * The `ping' plugin no longer uses `libping' but a self written
3356 library named `liboping'. With this library it's possible to ping
3357 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3359 2006-02-18, Version 3.7.2
3360 * A simple bug in the `battery' plugin has been fixed. It should now
3361 work with ACPI based batteries as well. Thanks to Sebastian for
3362 fixing this.
3363 * Fixing a bug that prevented collectd to be built without librrd.
3364 Thanks to Werner Heuser for reporting it.
3366 2006-02-04, Version 3.7.1
3367 * The new network code has been improved to build with older versions
3368 of glibc.
3369 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3370 to Tommie Gannert for this patch.
3372 2006-01-30, Version 3.7.0
3373 * The `battery' plugin has been added. It collects information about
3374 laptop batteries..
3375 * The MySQL plugin has been improved: It now writes two more RRD
3376 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3377 * The `cpufreq' plugin now reads another file since the file it did
3378 read so far causes much overhead in the kernel. Also, you need root
3379 to read the old file, but not to read the new one.
3380 * The `hddtemp' plugin can now be configured to connect to another
3381 address and/or port than localhost.
3382 * The `df' plugin now prefers `statvfs' over `statfs'.
3383 * The network code has been rewritten. collectd now supports unicast
3384 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3385 be set in the configfile.
3387 2006-01-24, Version 3.6.2
3388 * Due to a bug in the configfile handling collectd wouldn't start in
3389 client mode. This released fixes this.
3391 2006-01-20, Version 3.6.1
3392 * Due to a bug in `configure.in' all modules and the binary were
3393 linked against `libmysqlclient'. This issue is solved by this
3394 release.
3396 2006-01-17, Version 3.6.0
3397 * A config file has been added. This allows for loading only specific
3398 plugins.
3399 * A `df' plugin has been added.
3400 * A `mysql' plugin has been added.
3401 * The `ping' plugin doesn't entirely give up hope when a socket error
3402 occurred, but will back of and increase the intervals between tries.
3404 2006-01-21, Version 3.5.2
3405 * Fixed yet another bug in the signal handling.. Stupid typo..
3406 * Improved the ping plugin to not give up on socket errors (backport
3407 from 3.6.0).
3409 2005-12-18, Version 3.5.1
3410 * The PID-file is now deleted correctly when shutting down the daemon.
3411 * SIGINT and SIGTERM are now handled correctly.
3413 2005-12-16, Version 3.5.0 (Revision 326)
3414 * A bug in the `load' module under Solaris has been fixed.
3415 * The `users' module has been contributed by Sebastian Harl. It counts
3416 currently logged in users.
3417 * The CPU module now works under FreeBSD without the use of
3418 `libstatgrab', however SMP support is missing.
3419 * The default directories for the RRD files and the PID file now
3420 depend on the compile time setting of `localstatedir'.
3422 2005-11-15, Version 3.4.0 (Revision 236)
3423 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3424 from gentoo's bugzilla for writing the patch.
3425 * The build dependency for librrd has been removed. Binaries built
3426 without librrd are client-only and will multicast their value as
3427 with the `-c' argument.
3428 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3429 * The newly introduced `-f' switch prevents daemon initialization
3430 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3431 Barcellos for this patch.
3433 2005-11-04, Version 3.3.0 (Revision 216)
3434 * New modules have been added:
3435 - `serial', for monitoring traffic on the serial interfaces
3436 - `nfs', for graphing NFS procedure calls
3437 - `tape', traffic from/to tape devices
3438 * The memory.rrd now accepts more than 4Gig of memory.
3440 2005-10-26, Version 3.2.0 (Revision 200)
3441 * Support for graphing the processes has been added (thanks to Lyonel
3442 Vincent)
3443 * If reading from hddtemp fails collectd will increase the time
3444 between polls up to one day.
3445 * The init.d files have been improved.
3446 * Problems with the spec file have been fixed.
3448 2005-10-16, Version 3.1.0 (Revision 194)
3449 * Added the `setsid' syscall to the startup code.
3450 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3452 2005-09-30, Version 3.0.0 (Revision 184)
3453 * The ability to send/receive data to/from the network (think
3454 multicast) has been added.
3455 * Modules have been split up into shared libraries can be loaded at
3456 runtime. The biggest advantage is that the core program doesn't need
3457 to be linked against an external library.
3458 * A patch by George Kargiotakis has been applied: It fixes the sensors
3459 behaviour then more than one sensor is being queried.
3461 2005-09-16, Version 2.1.0 (Revision 172)
3462 * A module for swap statistics has been added.
3464 2005-09-09, Version 2.0.0 (Revision 135)
3465 * Filenames can no longer be configured at program startup. The only
3466 options as of this version are the directory and ping hosts.
3467 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3468 Soft-IRQ statistics are added to `System'.
3469 * Diskstats now collect read and write bytes, not sectors.
3470 * Ping statistics can now be collected for more than one host. There
3471 is no default any more: If no host is given no host will be pinged.
3472 * A self-written patch for libping has been applied so it builds
3473 cleanly.
3475 2005-09-01, Version 1.8.1 (Revision 123)
3476 * Much improved configure-script: libraries and features may now be
3477 disabled.
3478 * More detailed warnings/error messages when RRD update fails.
3480 2005-08-29, Version 1.8.0:
3481 * Support for collecting disk statistics under Solaris.
3483 2005-08-25, Version 1.7.0:
3484 * Support for libstatgrab[1] for load, memory usage and network
3485 traffic. CPU- and disk-usage are not (yet) supported, since
3486 libstatgrab returns insufficient information. I will contact the
3487 authors.
3488 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3489 aren't necessarily counted linear which is now handled correctly.

3492 2005-08-21, Version 1.6.0:
3493 * Basic support for Solaris: System load and cpu-usage can be
3494 collected under Solaris, too. Other stats will follow later.
3495 * Many fixes in the autoconf-script
3496 * Collection/Museum scripts have been added under contrib/museum
3497 * collectd may now be started in unprivileged mode, though ping
3498 statistics will not work.
3500 2005-07-17, Version 1.5.1:
3501 * Diskstats-RRDs now use major/minor for naming. Some systems have
3502 weird strings as disk-names..
3504 2005-07-17, Version 1.5:
3505 * A new module, diskstats, has been added. It collects information
3506 about the disks and partitions.
3508 2005-07-11, Version 1.4.2:
3509 * The meminfo module has been changed to work with more platforms
3510 and/or kernel versions.
3512 2005-07-10, Version 1.4.1: Correct traffic stats
3513 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3514 forgot to correct when I changed that module.
3516 2005-07-09, Version 1.4: More traffic stats
3517 * Traffic is now collected for all interfaces that can be found
3518 * Temperature-statistics are read from lm-sensors if available
3520 2005-07-08, Version 1.3: CPU stats
3521 * Collecting CPU statistics now
3523 2005-07-12, Version 1.2: Using syslog
3524 * collectd is now using the syslog facility to report errors, warnings
3525 and the like..
3526 * The default directory is now /var/db/collectd
3528 2005-07-10, Version 1.1: Minor changes
3529 * Nothing really useful to say ;)
3531 2005-07-09, Version 1.0: Initial Version
3532 * The following modules are provided:
3533 * Load average
3534 * Ping time
3535 * Traffic
3536 * Memory info
