2262 is linked with the shipped library, too.
2263 * java plugin: Delay creating the JVM until after the daemon has
2264 forked. The JVM internally creates threads that are lost when
2265 forking. This means that Java-based plugins are now configured
2266 during the init-phase, i. e. later than other plugins.
2267 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2268 to Alan Pevec for the patch.
2269 * network plugin: Fix the handling of the “CacheFlush” option: The

2291 details have been added to the configuration summary. Support for
2292 libtool 2.2 has been added.
2293 * collectd: Two bugs with the threshold checking have been fixed. The
2294 first one prevented thresholds to be checked at all, the second one
2295 caused wrong behavior with the persistency option. Thanks to Andrés
2296 J. Díaz for fixing these problems.
2297 * collectd: Handling of the `Include' configuration option has been
2299 * rrdtool plugin: Make sure initialization is run only once. This
2300 resolves problems under Solaris and potentially other systems.
2301 Thanks to Amit Gupta for reporting this bug.
2302 * java plugin: Make it possible to use dots ('.') instead of slashes
2303 ('/') as the class separator. Thanks to Randy Rizun for pointing
2305 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
2306 to Doug MacEachern for the patch.

2316 Linux' file-system based caching framework. Thanks to Edward
2317 Konetzko for the patch.
2318 * gmond plugin: The new gmond plugin can receive and interpret
2319 multicast traffic from Ganglia's gmond daemon.
2320 * java plugin: The new java plugin exports the collectd API to Java,
2321 making it possible to write extensions to collectd in Java.
2322 * memcachec plugin: The new memcachec plugin queries data from a
2323 memcached daemon and parses it similar to the cURL plugin. Thanks to
2324 Doug MacEachern for the initial code.
2325 * memcached plugin: Support for connections over UNIX domain sockets
2326 has been added. Thanks to Franck Lombardi for the patch.

2339 plugin must no longer be a multiple of the global interval.
2340 * table plugin: The new Table plugin provides parsing for table-like
2341 structured files, such as many files beneath /proc.
2342 * ted plugin: The new TED plugin reads power consumption measurements
2343 from “The Energy Detective” (TED). Thanks to Eric Reed for this
2345 * onewire plugin: The new `Interval' option allows collecting
2346 information from OneWire sensors at arbitrary intervals.
2347 * ping plugin: Support for collecting the drop rate and standard
2348 deviation of round-trip times has been added.
2349 * uptime plugin: The new uptime plugin can collect the server's
2350 uptime. Thanks to Marco Chiappero for the patch.
2352 2009-09-10, Version 4.6.5
2353 * collectd: Remove old values when a cache entry is marked as missing.
2354 This way the “GETVAL” command of the UnixSock plugin doesn't return
2355 old, no longer valid values when this happens. Thanks to Andrés J.
2357 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2358 to follow redirects. Thanks to Joey Hess for reporting this bug.
2359 * df plugin: Check the ignorelist before stating the file system,

2367 to Alan Pevec for the patch.
2368 * powerdns plugin: Set a timeout when reading data from the datagram
2369 socket. Handling of the “LocalSocket” option has been fixed. An
2370 incorrectly used “type” has been corrected. Thanks to Luke Heberling

2382 * Build system, various plugins: Many build fixes for FreeBSD,
2383 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2384 for many fixes and providing a build system for many platforms,
2385 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2386 providing an OpenBSD system.
2387 * collectd: Two bugs with the threshold checking have been fixed. The
2388 first one prevented thresholds to be checked at all, the second one
2389 caused wrong behavior with the persistency option. Thanks to Andrés
2390 J. Díaz for fixing these problems.
2391 * collectd: Handling of the `Include' configuration option has been

2407 * filter subsystem: Allow `Chains' without default targets.
2408 * liboping: A patch to comply with strict aliasing rules has been
2410 * timediff match: Fix a typo: The match was registered with a wrong
2411 name which prevented this match to be used as documented. Thanks to
2412 Bruno Prémont for finding this problem.
2413 * bind plugin: Fix collection of the cached RR sets. The number of RR
2414 sets currently in the cache was collected as a counter value, which
2415 is nonsense. Thanks to Bruno Prémont for implementing this.
2416 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2417 primarily BSDs, don't take it well and crash.
2418 * oracle plugin: Portability to 64 bit systems has been improved.
2419 * postgresql plugin: The default configuration has been improved.
2420 * rrdtool plugin: Fix a possible race condition: If the network plugin

2431 faults. Thanks to Peter Holik for his patch.
2433 2009-02-16, Version 4.6.0
2434 * collectd: Added the `filter chain' infrastructure, which allows the
2435 user to use `matches' and `targets' to control value processing.
2436 * collectd: The new `-T' command line argument allows more in-depth
2437 testing of a configuration. Thanks to Doug MacEachern for the patch.
2438 * collectd-nagios: The Nagios integration command has been updated to
2439 use libcollectdclient. The `percentage' aggregation function has
2440 been added. Thanks to Fabian Linzberger for the patch.

2453 Bruno Prémont for this plugin.
2454 * cpu plugin: Report `interrupt' separately when using
2455 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
2456 example for native OpenBSD support, has been added. Thanks to Simon
2457 Kuhnle for the patch.
2458 * csv plugin: Make it possible to write values to STDOUT instead of
2459 files. This is meant for testing purposes mostly. The output written
2460 to STDOUT is compatible with the exec plugin. Thanks to Doug
2461 MacEachern for the patch.
2462 * curl plugin: This new plugin can be used to read web pages and parse
2463 them using the same mechanism that's used in the tail plugin.
2464 * dbi plugin: This new plugin allows you to connect to a variety of
2465 relational databases and use SQL to gather custom statistics from
2466 it. It is similar to the already existing PostgreSQL plugin but uses
2467 libdbi to communicate with the database(s).
2468 * interface plugin: Use the ignorelist framework when selecting /
2469 ignoring interfaces. This allows one to use regular expressions to
2470 select interfaces, too.
2471 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2472 Thanks to Bruno Prémont for this patch.
2473 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

2486 * perl plugin: Export the newly added plugin_write() to Perl plugins.
2487 * perl plugin: Added support for `notification meta data'.
2488 * perl plugin: Added support for the `filter chain' infrastructure by
2489 allowing plugins to register `matches' and `targets'.
2490 * postgresql plugin: The preferred configuration syntax has been
2491 updated to be in line with the syntax used by the new dbi and oracle
2492 plugins. The compatibility code for the old syntax is present.
2493 Support for the new `Result' blocks and the interval parameter has
2495 * processes plugin: Stacksize and virtual memory usage statistics have
2496 been added. Portability fixes.
2497 * rrdcached plugin: This new plugin uses the (still in development)
2498 RRD accelerator daemon, rrdcached. This daemon works very similar to
2499 the original rrdtool plugin of collectd, but adds some more nice
2501 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2504 2009-05-09, Version 4.5.4
2505 * Build system, various plugins: Many build fixes for FreeBSD,
2506 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

2517 Tomasz Pala for the patch.
2518 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2520 * rrdtool plugin: Fix a possible race condition: If the network plugin
2521 is initialized and dispatches a value before the rrdtool plugin is
2522 initialized, the daemon may crash.
2523 * memory plugin: Fix a potential problem under Solaris.
2525 2009-02-22, Version 4.5.3

2535 code. Thanks to "thated" for reporting this.
2537 2009-01-02, Version 4.5.2
2538 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2539 file may be in both locations, especially when the database was
2540 installed in a non-standard path. Thanks to Dusty Doris for
2542 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2543 Solaris, in the configure script automatically.
2544 * build system, tcpconns plugin: Check for `kvm_nlist' and
2545 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2546 library with similar functions to the BSD variant, but doesn't
2547 provide these necessary functions.
2548 * collectd.conf(5): Various fixes and clarifications.
2549 * collectd: Remove a GNUism (unnamed unions), thus improving
2551 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2552 This solves portability problems, especially for Solaris.
2553 * dns plugin: Fix a portability problem with NetBSD.
2554 * filecount plugin: Fix an off-by-one error. This error may cause a
2556 * network plugin: Fix the handling of `type' in the network protocol.
2557 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2558 much larger buffer. This caused the `type' to be transferred much
2559 more often than necessary. In some cases, e. g. the `cpu' and
2560 `cpufreq' plugins being used at the same time, data may be corrupted
2561 in those files. Thanks to Bruno Prémont for debugging and reporting
2563 * processes plugin: Fix a possible segmentation fault when specifying
2564 invalid configuration options.
2565 * unixsock plugin: Make sure the initialization function is run only
2566 once. This resolves a file descriptor leak under systems which run
2567 the initialization more than once, such as Solaris.
2569 2008-10-16, Version 4.5.1
2570 * build system: Change `--enable-<plugin>' to abort with an error if
2571 dependencies are not met. Thanks to Bruno Prémont for the patch.
2572 Also, the poisoning of various string functions has been restricted
2574 * collectd: Fix a memory leak in the global value cache. With every
2575 *missing* value a couple of bytes would be leaked. Another memory
2576 leak in the configuration handling code has been fixed. Thanks to
2577 Niraj Tolia for reporting these issues.
2578 * collectd: Fix an off-by-one error in the ignorelist functionality.
2579 When using regular expressions, the last character would be missing,
2580 possibly matching differently from what one would expect.
2581 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2583 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2584 Linzberger for reporting the bug.
2585 * iptables plugin: Fix an off-by-one error. If a string was just one
2586 character too long, it was truncated instead of reporting an error.
2587 * network plugin: Fix a memory leak in the configuration handling
2588 code. Thanks to Niraj Tolia for reporting this issue.
2589 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2590 * postgresql plugin: Don't reopen connection during reinitialization.
2591 This fixes a bug under Solaris and potentially other platforms.
2592 Missing calls to `PQclear' have been added, too. This fixes memory
2593 leaks. Thanks to ``Admin'' for reporting these bugs.
2594 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2596 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2597 problems with some `libc's. Thanks to Matthias Lay for reporting the
2600 2008-09-04, Version 4.5.0
2601 * collectd: Added the ability to flush certain identifiers.

2604 * filecount plugin: The new filecount plugin counts the number of
2605 files in a directory and its subdirectories.
2606 * ipmi plugin: Sensor names have been changed to ensure unique names.
2607 Notifications upon added and removed sensors can now be generated.
2608 * notify_desktop plugin: This new plugin sends notifications to the
2609 X desktop using the structure defined in the `Desktop Notification
2611 * notify_email plugin: This new plugin sends out notifications via
2612 email, using the `esmtp' library.
2613 * onewire plugin: The new experimental(!) onewire plugin reads values,
2614 such as temperatures, from sensors connected to the computer via the
2616 * perl plugin: Improved synchronized access to internal data structures
2617 and fixed a possible dead-lock.
2618 * perl plugin: Added the ability to flush certain identifiers and marked
2619 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2621 * perl plugin: Added the ability to configure Perl plugins.
2622 * postgresql plugin: The new postgresql plugin collects statistics
2623 about or from a PostgreSQL database.

2629 using Linux ACPI thermal zone data.
2631 2009-01-02, Version 4.4.5
2632 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2633 file may be in both locations, especially when the database was
2634 installed in a non-standard path. Thanks to Dusty Doris for
2636 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2637 Solaris, in the configure script automatically.
2638 * collectd.conf(5): Various fixes and clarifications.

2640 portability problems, especially for Solaris.
2641 * dns plugin: Fix a portability problem with NetBSD.
2642 * network plugin: Fix the handling of `type' in the network protocol.
2643 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2644 much larger buffer. This caused the `type' to be transferred much
2645 more often than necessary. In some cases, e. g. the `cpu' and
2646 `cpufreq' plugins being used at the same time, data may be corrupted
2647 in those files. Thanks to Bruno Prémont for debugging and reporting
2649 * unixsock plugin: Make sure the initialization function is run only

2695 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2697 * wireless plugin: Work around incorrect noise and power values
2698 returned by some broken drivers.

2712 2008-05-06, Version 4.4.0
2713 * collectd: Internal code cleanups.
2714 * collectd: Added support for a `Flush' command in the unixsock and
2715 exec plugins. This command can be used to force a plugin (or all) to
2716 flush its values to disk.
2717 * collectd: Thresholds can now be configured to apply to one data
2718 source only, making it possible to configure different thresholds
2719 for each data source.
2720 * apache, nginx plugins: Added the possibility to disable host and/or
2722 * ascent plugin: The new ascent plugin reads and parses the statistics
2723 page of an Ascent server.
2724 * cpu plugin: Support for the statgrab library has been added.
2725 * disk plugin: The possibility to ignore certain disks or collect only
2726 specific disks has been added.

2729 sensor values via IPMI, the intelligent platform management
2731 * iptables plugin: The iptc library that is used by the iptables
2732 plugin has been added to the distribution, because it is not
2733 provided by all distributions and removed from at least one.
2734 * powerdns plugin: The new powerdns plugin reads statistics from an
2735 authoritative or a recursing PowerDNS name server.
2736 * rrdtool plugin: The size of the files generated with the default
2737 configuration has been decreased.
2738 * tail plugin: The new tail plugin can be used to gather statistics by
2739 continuously reading from log files.
2740 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2741 TeamSpeak2 server and collects statistics about the number of users
2742 and number of channels.
2743 * users plugin: Support for the statgrab library has been added.
2744 * vmem plugin: The new vmem plugin collects very detailed statistics
2745 about the virtual memory subsystem of Linux.
2747 2008-08-30, Version 4.3.4
2748 * Build system: Improved detection of and linking with the statgrab
2750 * collectd: Portability fixes, especially to determine endianness more
2752 * Various plugins: Fix format strings.
2753 * disk plugin: A fix for giving disks under Linux 2.4 the right names
2754 again has been applied.
2755 * memcached plugin: Fix a too short timeout and a related file
2757 * memory plugin: A typo in the libstatgrab code has been fixed.
2758 * network plugin: A fix in the initialization function solves problems
2760 * nginx plugin: A thread-unsafe function has been replaced.
2761 * vserver plugin: A thread-unsafe function has been replaced.
2762 * wireless plugin: A work-around for broken wireless drivers has been
2765 2008-04-22, Version 4.3.3
2766 * build system: Improved detection of several libraries, especially if
2767 they are in non-standard paths.
2768 * build system: Portability fixes: Automatically define "_REENTRANT"
2769 if the libc expects it.
2770 * collectd: Error and warning messages have been improved.
2771 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2773 * apache plugin: Allocate new memory when reading a webpage instead of
2774 using a buffer of static size.
2775 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2777 * hddtemp plugin: Error and warning messages have been improved.
2778 * sensors plugin: Fix sensor collection for some chip types.
2780 2008-03-29, Version 4.3.2
2781 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2782 `Persist' threshold options.
2783 * collectd: Fix handling of missing values in the global value cache.
2784 * collectd: Improved error messages when parsing the configuration.
2785 * sensors plugin: Fix temperature collection with libsensors4.
2786 * unixsock plugin: Fix mixed input and output operation on streams.
2787 * wireless plugin: Fix reading noise value.
2789 2008-03-05, Version 4.3.1
2790 * exec plugin: Set supplementary group IDs.
2792 + Use `memcpy' when constructing/parsing a package to avoid
2793 alignment problems on weird architectures, such as Sparc.
2794 + Translate doubles to/from the x86 byte representation to ensure
2795 cross-platform compatibility.
2796 * ping plugin: Correct the handling of the `TTL' setting.
2797 * swap plugin: Reapply a patch for Solaris.
2798 * tcpconns plugin: Portability improvements.
2800 2008-02-18, Version 4.3.0
2801 * collectd: Notifications have been added to the daemon. Notifications
2802 are status messages that may be associated with a data instance.
2803 * collectd: Threshold checking has been added to the daemon. This
2804 means that you can configure threshold values for each data
2805 instance. If this threshold is exceeded a notification will be
2807 * collectd: The new `FQDNLookup' option tells the daemon to use the
2808 full qualified domain name as the hostname, not just the host part
2809 es returned by `gethostname(2)'.
2810 * collectd: Support for more than one `TypesDB' file has been added.
2811 This is useful when one such file is included in a package but one
2812 wants to add custom type definitions.
2813 * collectd: The `Include' config option has been expanded to handle
2814 entire directories and shell wildcards.
2815 * collectdmon: The new `collectdmon' binary detects when collectd
2816 terminates and automatically restarts it again.
2817 * csv plugin: The CSV plugin is now able to store counter values as a
2818 rate, using the `StoreRates' configuration option.
2819 * exec plugin: Handling of notifications has been added and the
2820 ability to pass arguments to the executed programs has been added.
2821 * hddtemp plugin: The new `TranslateDevicename' option lets you
2822 disable the translation from device names to major-minor-numbers.
2823 * logfile plugin: Handling of notifications has been added.
2824 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
2825 domain name lookups in this plugin.
2826 * perl plugin: Many internal changes added support for handling multiple
2827 threads making the plugin reasonably usable inside collectd. The API has
2828 been extended to support notifications and export global variables to
2829 Perl plugins; callbacks now have to be identified by name rather than a
2830 pointer to a subroutine. The plugin is no longer experimental.
2831 * uuid plugin: The new UUID plugin sets the hostname to an unique
2832 identifier for this host. This is meant for setups where each client
2833 may migrate to another physical host, possibly going through one or
2834 more name changes in the process. Thanks to Richard Jones from
2835 Red Hat's Emerging Technology group for this plugin.
2836 * libvirt: The new libvirt plugin uses the `libvirt' library to query
2837 CPU, disk and network statistics about guest systems on the same
2838 physical server. Thanks to Richard Jones from Red Hat's Emerging
2839 Technology group for this plugin.
2841 2008-04-22, Version 4.2.7
2842 * build system: Improved detection of several libraries, especially if
2843 they are in non-standard paths.
2844 * build system: Portability fixes: Automatically define "_REENTRANT"
2845 if the libc expects it.
2846 * collectd: Error and warning messages have been improved.
2847 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2849 * apache plugin: Allocate new memory when reading a webpage instead of
2850 using a buffer of static size.
2851 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2853 * hddtemp plugin: Error and warning messages have been improved.
2854 * sensors plugin: Fix sensor collection for some chip types.
2856 2008-03-29, Version 4.2.6
2857 * collectd: Improved error messages when parsing the configuration.
2858 * sensors plugin: Fix temperature collection with libsensors4.
2859 * unixsock plugin: Fix mixed input and output operation on streams.
2860 * wireless plugin: Fix reading noise value.
2862 2008-03-04, Version 4.2.5
2863 * apache plugin: Improved initialization and error messages.
2864 * exec plugin: Set supplementary group IDs.
2866 + Create separate threads for reading from the socket and parsing
2867 and dispatching incoming packets. Versions prior to this may have
2868 problems in high-load situations, where the socket receive buffers
2869 overflows, resulting in gaps in the data.
2870 + Use `memcpy' when constructing/parsing a package to avoid
2871 alignment problems on weird architectures, such as Sparc.
2872 + Translate doubles to/from the x86 byte representation to ensure
2873 cross-platform compatibility.
2874 * ping plugin: Correct the handling of the `TTL' setting.
2875 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
2876 * swap plugin: Reapply a patch for Solaris.
2877 * tcpconns plugin: Portability improvements.
2879 2008-01-21, Version 4.2.4
2880 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2881 the permission on the socket as documented in the manpage. Thanks to
2882 Evgeny Chukreev for fixing this issue.
2883 * collectd: The documentation has been improved.
2885 2007-12-28, Version 4.2.3
2886 * sensors plugin: Updated the plugin to build and work with version 3
2887 of the libsensors library.
2889 2007-12-15, Version 4.2.2
2890 * nginx plugin: Incorrect comparison of strings lead to a segfault
2891 when using the plugin. Thanks to Saulius Grigaliunas for fixing
2893 * logfile plugin: The config option `Timestamp' was handled
2894 incorrectly and basically always active. Thanks to Luke Heberling
2897 2007-11-08, Version 4.2.1
2898 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
2899 enabled on the host.
2900 * snmp plugin: Fix a memory leak.
2902 2007-10-27, Version 4.2.0
2903 * collectd: The new config option `Include' lets you include other
2904 configfiles and thus split up your config into smaller parts. This
2905 may be especially interesting for the snmp plugin to keep the data
2906 definitions separate from the host definitions.
2907 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
2908 (number of connections, octets and packets for each service and
2909 destination). Thanks to Sebastian Harl for this plugin.
2910 * memcached plugin: The new `memcached' plugin connects to a memcached
2911 daemon process and collects statistics of this distributed caching
2912 system. Thanks to Antony Dovgal for contributing this plugin.
2913 * nginx plugin: The new `nginx' plugin reads the status page of an
2914 nginx daemon and saves the handled connections and requests.
2915 * perl plugin: Many changes, including the added `EnableDebugger'
2916 config option which lets you debug your Perl plugins more easily.
2917 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2918 be more thread-safe otherwise by locking calls to the library.
2919 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
2920 correct the values returned by SNMP-agents. If a <data> block is
2921 defined as `table' the instance is now optional. The sequence number
2922 is used as the type-instance in this case. The new `InstancePrefix'
2923 option allows to add arbitrary prefixes to the type-instance.
2924 * tcpconns plugin: The new `tcpconns' plugin collects the number of
2925 certain TCP connections and what state they're in. This can be used
2926 to see how many connections your FTP server has to handle or how
2927 many outgoing connections your mailserver has open.
2929 2008-01-11, Version 4.1.6
2930 * unixsock plugin: A bug in the unixsock plugin caused it not to set
2931 the permission on the socket as documented in the manpage. Thanks to
2932 Evgeny Chukreev for fixing this issue.
2933 * collectd: The documentation has been improved.
2935 2007-12-27, Version 4.1.5
2936 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

2939 of the libsensors library.
2941 2007-11-08, Version 4.1.4
2942 * Build system: Improve detection of the rrd library, especially if
2943 it's in a non-standard location.
2944 * Build system: A bug when parsing the argument for
2945 `--with-libnetsnmp' has been fixed.
2946 * collectd: Implement `strerror_r' if the libc doesn't provide it.
2947 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
2948 a deadlock or delay when shutting down the daemon.
2949 * snmp plugin: Fix a memory leak.
2951 2007-10-24, Version 4.1.3
2952 * collectd: A build issue under Solaris has been resolved by renaming
2954 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
2955 be more thread-safe otherwise by locking calls to the library.
2957 2007-09-28, Version 4.1.2
2958 * apcups plugin: Fix reporting of the `load percent' data.
2959 * wireless plugin: Correct the handling of cards returning signal and
2960 noise quality as percentage.
2961 * perl plugin: Fix a possible buffer overflow in get_module_name().
2962 * build system: Further improve the detection of libraries.
2963 * netlink plugin: Build issues under some older versions of the Linux
2964 includes (i. e. Debian Sarge) have been fixed.
2965 * snmp plugin: Fix a potential segfault when a host times out. Add
2966 support for the `timeticks' type.
2968 2007-09-12, Version 4.1.1
2969 * Build system: The detection of `libnetlink' has been improved.
2970 * collectd: The documentation has been fixed in numerous places.
2971 * exec plugin: Setting the group under which to run a program has been
2973 * collectd: The `sstrerror' function was improved to work correctly
2974 with the broken GNU version of `strerror_r'.
2975 * collectd: Write an error message to STDERR when loading of a plugin
2977 * apcups plugin: Fix the `types' used to submit the values: They still
2978 has an `apcups_' prefix which doesn't work anymore.
2979 * rrdtool plugin: Create new RRD-files with the `begin' time set to
2980 whatever the client thinks is `now'..
2982 2007-09-01, Version 4.1.0
2983 * Build system: The build system has been changed to automatically
2984 disable all plugins, which are missing dependencies. The dependency
2985 checking has been removed from the plugins themselves to remove
2987 * Flexible interval: The interval of collected data is now sent along
2988 with the data itself over the network, so that the interval-settings
2989 of server and clients no longer needs to match.
2990 * netlink plugin: The new `netlink' plugin connects to the Linux
2991 kernel using a netlink socket and uses it to query information about
2992 interfaces, qdiscs and classes.
2993 * rrdtool plugin: The cache is now dumped to disk in an extra thread
2994 to not block data collection.
2995 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
2996 network devices, such as switches, routers, thermometers, rack
2997 monitoring servers, etc. The collectd-snmp(5) manpage documents this
2999 * unixsock plugin: Added the `LISTVAL' command.
3000 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3001 of music played with xmms.
3003 2007-09-28, Version 4.0.9
3004 * apcups plugin: Fix reporting of the `load percent' data.
3005 * wireless plugin: Correct the handling of cards returning signal and
3006 noise quality as percentage.
3007 * perl plugin: Fix a possible buffer overflow in get_module_name().
3009 2007-09-12, Version 4.0.8
3010 * collectd: The `sstrerror' function was improved to work correctly
3011 with the broken GNU version of `strerror_r'.
3012 * collectd: Write an error message to STDERR when loading of a plugin
3014 * apcups plugin: Fix the `types' used to submit the values: They still
3015 has an `apcups_' prefix which doesn't work anymore.
3016 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3017 whatever the client thinks is `now'..
3019 2007-08-26, Version 4.0.7
3020 * documentation: Some typos have been fixed and some information has
3022 * build system: Many fixes for detecting libraries in unusual places,
3023 such as on RedHat systems. The affected libraries are `libcurl',
3024 `libmysql', and `libupsclient'.
3025 * network plugin: Allow the `Port' option to be specified as a number
3026 (i. e. without quotes).
3027 * nut plugin: A fix allows linking the nut plugin against
3028 libupsclient, version >= 2.2.0.
3029 * processes plugin: Fix a potential segmentation fault.
3031 2007-07-30, Version 4.0.6
3032 * sensors plugin: Fix the ignorelist functionality: Only the `type
3033 instance' was used to match against the list, but the documentation
3034 told otherwise. This release fixes the code, so it complies with the
3036 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3037 configuration messages will end up in the logging facility.
3038 * conrtib/fedora: The contributed specfile for Fedora has been
3041 2007-07-05, Version 4.0.5
3042 * Portability: More fixes for OpenBSD have been included.
3044 2007-06-24, Version 4.0.4
3045 * cpu plugin: Fixed the Solaris code.

3047 * interface plugin: Fixed the Solaris code.
3048 * load plugin: Fixed the alternative `/proc' Linux code.
3049 * memory plugin: Fixed the Solaris code.
3050 * oconfig: Don't require `-lfl' anymore.
3052 2007-06-19, Version 4.0.3
3053 * cpu plugin: Fix the Darwin / Mac OS X code.
3054 * ping plugin: Use the return value of `getpid', not its address.
3055 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3056 initialized correctly.
3057 * configure: Added `--with-nan-emulation' to aid cross compilation.
3059 2007-06-12, Version 4.0.2
3060 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3061 they're given in numerically form.
3063 2007-06-07, Version 4.0.1
3064 * iptables plugin: A bug in the configuration routine has been fixed.
3065 Setting a comment in the configfile will no longer cause a
3068 2007-06-03, Version 4.0.0
3069 * collectd: The plugin-infrastructure has been changed to allow for
3070 more types of plugins, namely `write' and `log' plugins.
3071 * collectd: The read-function has been changed to read many plugins in
3072 parallel, using threads. Thus, plugins generally need to use
3073 thread-safe functions from now on.
3074 * collectd: The '-t' command line options allows to perform syntax tests
3075 of the configuration file and exit immediately.
3076 * csv plugin: The new `csv' plugin handles output to `comma separated
3078 * rrdtool plugin: The new `rrdtool' plugin handles output to
3079 RRD-files. Data can be cached to combine multiple updates into one
3080 write to increase IO-performance.
3081 * network plugin: The new `network' plugin handles IO via the network.
3082 It implements a different, much more extensible protocol which can
3083 combine many values in one packet, decreasing the number of UDP-
3084 packets being sent. It can read from and send to the network and
3085 with the appropriate configuration even forward packets to other
3087 * unixsock plugin: The new `unixsock' plugin provides an interface to
3088 communicate with the daemon while it is running. Right now the
3089 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3091 * perl plugin: The new `perl' plugin allows you to write extensions
3092 for collectd in the scripting-language Perl.
3093 * logfile plugin: The new `logfile' plugin writes logmessages to files
3094 or STDOUT or STDERR.
3095 * syslog plugin: The new `syslog' plugin sends logmessages to the
3096 system's syslog daemon.
3097 * entropy plugin: The new `entropy' plugin collects the amount of
3098 entropy currently being available to the system.
3099 * exec plugin: The new `exec' plugin forks child processes and reads
3100 back values provided by the forked processes.
3101 * iptables plugin: The new `iptables' plugin reads counters from
3102 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3104 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3105 to Peter Holik for contributing this plugin.
3106 * nut plugin: The new `nut' plugin connects the upsd of the `network
3107 ups tools' and reads information about the connected UPS.
3108 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3109 connections) field was added by Florent Monbillard.
3110 * collectd-nagios: The new `collectd-nagios' binary queries values
3111 from collectd, parses them and exits according to Nagios-standards.
3112 * manpages: The manpages have been improved a lot.
3114 2007-09-28, Version 3.11.7
3115 * wireless plugin: Correct the handling of cards returning signal and
3116 noise quality as percentage.
3118 2007-08-31, Version 3.11.6
3119 * processes plugin: Fix a potential segmentation fault.
3121 2007-05-29, Version 3.11.5
3122 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3123 * ntpd plugin: Fix a potential buffer overflow.
3124 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3125 were accounted as `zombies'.
3127 2007-04-10, Version 3.11.4
3128 * dns plugin: Change the order of includes to make the plugin compile
3131 2007-03-30, Version 3.11.3
3132 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3133 of the unused `COLLECT_KSTAT'.
3135 2007-02-11, Version 3.11.2
3136 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3137 NULL-pointer may have been passed to `printf' which causes a
3138 segfault with some libcs.
3140 2007-02-10, Version 3.11.1
3141 * df plugin: Some wrong defines have been fixed so the plugin works
3142 under Solaris again.
3143 * dns plugin: The usage of a struct has been fixed to work with
3145 * processes plugin: Some missing defines have been added so the plugin
3146 compiles cleanly under FreeBSD and presumably other UNIXes.
3148 2006-12-22, Version 3.11.0
3149 * collectd: The new command line option `-P' makes it easier for
3150 distributors to change the location of PID-files.
3151 * collectd: The daemon shuts down faster now which makes it easier to
3152 write init.d-scripts for it.
3153 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3154 caused problems every now and then.
3155 * df plugin: New config options allow to ignore certain mountpoints,
3156 filesystem types or devices.
3157 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3158 and interprets it. It collects traffic as well as qtype, opcode and
3160 * email plugin: Sebastian Harl has contributed this plugin which
3161 counts received mails in categories (e. g. ham, spam, virus), spam
3162 score (as given by SpamAssassin) and check types.
3163 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3164 uses `mbmon' to gather information from sensors on the motherboard.
3165 * processes plugin: Collect detailed statistics for configured
3166 processes, that's process and thread count, CPU usage, resident
3167 segment size and pagefaults.
3168 * multimeter plugin: Peter Holik contributed a new plugin which
3169 queries multimeters.
3170 * sensors plugin: Lubos Stanek has put much effort into improving this
3171 plugin, including `extended naming', collection of voltage values
3172 and the possibility to ignore certain values.
3174 2006-12-21, Version 3.10.4
3175 * Max Kellermann has identified a bug in the server routine: When
3176 opening a socket fails the daemon will (re)try opening the socket in
3177 an endless loop, ultimately leading to a `EMFILE' error.
3179 2006-11-04, Version 3.10.3
3180 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3181 ntpd's reply was sent in more than one packet, the buffer size was
3182 calculated incorrectly, resulting in the reading of uninitialized or
3185 2006-11-01, Version 3.10.2
3186 * The sample config file has been improved.
3187 * Errors in the manpages have been corrected.
3188 * The ping-plugin now adds hosts during initialization, not during
3189 startup. This speeds up startup when no network connectivity is
3190 available. Also, the hosts are being added later when the network is
3192 * Improved BSD-support for the df-plugin.
3193 * Fixed syntax errors in the swap-plugin for Mac OS X.
3194 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3196 * Don't disable the mysql-plugin if connecting to the database fails
3197 during initialization. Instead, try again in increasing intervals.
3199 2006-07-19, Version 3.10.1
3200 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3201 the apcups cannot be reached, unconnected sockets will pile up and
3202 eventually lead to `Too many open files' errors.
3204 2006-07-09, Version 3.10.0
3205 * The `disk' plugin has been ported to Darwin.
3206 * The `battery' plugin should work on many Apple computers now.
3207 * The `traffic' plugin can now ignore certain interfaces. Also,
3208 statistics for sent/received packets and errors have been added.

3212 * A plugin for monitoring an NTP instance and the local clock drift
3215 2006-06-25, Version 3.9.4
3216 * The Solaris code in the `swap' plugin has been changed to reflect
3217 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3219 * The debugging system has been fixed to work with the Sun libc.
3220 * When built without librrd the variable `operating_mode' could be
3221 uninitialized. Thanks to David Elliot for reporting the bug.
3223 2006-06-01, Version 3.9.3
3224 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3225 operating systems also profit from the changes, but I wasn't able to
3227 * Changed the build system to find the netinet-includes under FreeBSD
3228 and therefore successfully build the `liboping' library there.
3230 2006-05-09, Version 3.9.2
3231 * Applied a patch to the `liboping' library. Due to a bug in the
3232 sequence checking the `ping' plugin stopped working after
3233 approximately 7.6 days.
3235 2006-05-09, Version 3.8.5
3236 * Applied a patch to the `liboping' library. Due to a bug in the
3237 sequence checking the `ping' plugin stopped working after
3238 approximately 7.6 days.
3240 2006-04-21, Version 3.9.1
3241 * Build issues with Solaris and possible other architectures have been
3243 * Problems when building the `apache'-plugin without `libcurl' have
3245 * A bug in the `ping' plugin has been fixed. Sorry folks.
3247 2006-04-02, Version 3.9.0
3248 * A plugin to monitor the Apache webserver has been added.
3249 <http://httpd.apache.org/>
3250 * A plugin to collect statistics about virtual servers using VServer.
3251 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3253 * A plugin for wireless LAN cards has been added. It monitors signal
3254 strength, link quality and noise ratio..
3255 * A plugin for Apple hardware sensors has been added.
3256 * An option to compile collectd with different `step' and `heartbeat'
3257 settings has been added. The size of RRAs is no longer static but
3258 calculated based on the settings for `step' and `width'.
3259 * The `ping' plugin can now be configured to use a certain TTL.
3260 * A plugin to monitor the hardware sensors of Apple computers has been
3262 * The plugins `cpu', `memory', `processes' and `traffic' have been
3263 ported to Mach/Darwin (Mac OS X).
3264 * The `log mode' has been contributed by Christophe Kalt. It writes
3265 the data into text files rather than RRD files.
3267 2006-04-09, Version 3.8.4
3268 * Applied patch by Vincent Stehlé which improves the disk-name
3269 resolution in the `hddtemp' plugin for Linux systems.
3271 2006-04-02, Version 3.8.3
3272 * Applied a patch by James Byers: The MySQL plugin was not working
3273 with MySQL 5.0.2 or later.
3275 2006-03-14, Version 3.8.2
3276 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3277 the GNU libc, because it points to `/etc/fstab' rather than
3280 2006-03-13, Version 3.8.1
3281 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3282 * Fixes in the debian `postinst' and `init.d' scripts.
3284 2006-03-09, Version 3.8.0
3285 * The `ping' plugin no longer uses `libping' but a self written
3286 library named `liboping'. With this library it's possible to ping
3287 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3289 2006-02-18, Version 3.7.2
3290 * A simple bug in the `battery' plugin has been fixed. It should now
3291 work with ACPI based batteries as well. Thanks to Sebastian for
3293 * Fixing a bug that prevented collectd to be built without librrd.
3294 Thanks to Werner Heuser for reporting it.
3296 2006-02-04, Version 3.7.1
3297 * The new network code has been improved to build with older versions
3299 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3300 to Tommie Gannert for this patch.
3302 2006-01-30, Version 3.7.0
3303 * The `battery' plugin has been added. It collects information about
3305 * The MySQL plugin has been improved: It now writes two more RRD
3306 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3307 * The `cpufreq' plugin now reads another file since the file it did
3308 read so far causes much overhead in the kernel. Also, you need root
3309 to read the old file, but not to read the new one.
3310 * The `hddtemp' plugin can now be configured to connect to another
3311 address and/or port than localhost.
3312 * The `df' plugin now prefers `statvfs' over `statfs'.
3313 * The network code has been rewritten. collectd now supports unicast
3314 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3315 be set in the configfile.
3317 2006-01-24, Version 3.6.2
3318 * Due to a bug in the configfile handling collectd wouldn't start in
3319 client mode. This released fixes this.
3321 2006-01-20, Version 3.6.1
3322 * Due to a bug in `configure.in' all modules and the binary were
3323 linked against `libmysqlclient'. This issue is solved by this
3326 2006-01-17, Version 3.6.0
3327 * A config file has been added. This allows for loading only specific
3329 * A `df' plugin has been added.
3330 * A `mysql' plugin has been added.
3331 * The `ping' plugin doesn't entirely give up hope when a socket error
3332 occurred, but will back of and increase the intervals between tries.
3334 2006-01-21, Version 3.5.2
3335 * Fixed yet another bug in the signal handling.. Stupid typo..
3336 * Improved the ping plugin to not give up on socket errors (backport
3339 2005-12-18, Version 3.5.1
3340 * The PID-file is now deleted correctly when shutting down the daemon.
3341 * SIGINT and SIGTERM are now handled correctly.
3343 2005-12-16, Version 3.5.0 (Revision 326)
3344 * A bug in the `load' module under Solaris has been fixed.
3345 * The `users' module has been contributed by Sebastian Harl. It counts
3346 currently logged in users.
3347 * The CPU module now works under FreeBSD without the use of
3348 `libstatgrab', however SMP support is missing.
3349 * The default directories for the RRD files and the PID file now
3350 depend on the compile time setting of `localstatedir'.
3352 2005-11-15, Version 3.4.0 (Revision 236)
3353 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3354 from gentoo's bugzilla for writing the patch.
3355 * The build dependency for librrd has been removed. Binaries built
3356 without librrd are client-only and will multicast their value as
3357 with the `-c' argument.
3358 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3359 * The newly introduced `-f' switch prevents daemon initialization
3360 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3361 Barcellos for this patch.
3363 2005-11-04, Version 3.3.0 (Revision 216)
3364 * New modules have been added:
3365 - `serial', for monitoring traffic on the serial interfaces
3366 - `nfs', for graphing NFS procedure calls
3367 - `tape', traffic from/to tape devices
3368 * The memory.rrd now accepts more than 4Gig of memory.
3370 2005-10-26, Version 3.2.0 (Revision 200)
3371 * Support for graphing the processes has been added (thanks to Lyonel
3373 * If reading from hddtemp fails collectd will increase the time
3374 between polls up to one day.
3375 * The init.d files have been improved.
3376 * Problems with the spec file have been fixed.
3378 2005-10-16, Version 3.1.0 (Revision 194)
3379 * Added the `setsid' syscall to the startup code.
3380 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3382 2005-09-30, Version 3.0.0 (Revision 184)
3383 * The ability to send/receive data to/from the network (think
3384 multicast) has been added.
3385 * Modules have been split up into shared libraries can be loaded at
3386 runtime. The biggest advantage is that the core program doesn't need
3387 to be linked against an external library.
3388 * A patch by George Kargiotakis has been applied: It fixes the sensors
3389 behaviour then more than one sensor is being queried.
3391 2005-09-16, Version 2.1.0 (Revision 172)
3392 * A module for swap statistics has been added.
3394 2005-09-09, Version 2.0.0 (Revision 135)
3395 * Filenames can no longer be configured at program startup. The only
3396 options as of this version are the directory and ping hosts.
3397 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3398 Soft-IRQ statistics are added to `System'.
3399 * Diskstats now collect read and write bytes, not sectors.
3400 * Ping statistics can now be collected for more than one host. There
3401 is no default any more: If no host is given no host will be pinged.
3402 * A self-written patch for libping has been applied so it builds
3405 2005-09-01, Version 1.8.1 (Revision 123)
3406 * Much improved configure-script: libraries and features may now be
3408 * More detailed warnings/error messages when RRD update fails.
3410 2005-08-29, Version 1.8.0:
3411 * Support for collecting disk statistics under Solaris.
3413 2005-08-25, Version 1.7.0:
3414 * Support for libstatgrab[1] for load, memory usage and network
3415 traffic. CPU- and disk-usage are not (yet) supported, since
3416 libstatgrab returns insufficient information. I will contact the
3418 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3419 aren't necessarily counted linear which is now handled correctly.
3420 [1]: http://www.i-scream.org/libstatgrab/
3422 2005-08-21, Version 1.6.0:
3423 * Basic support for Solaris: System load and cpu-usage can be
3424 collected under Solaris, too. Other stats will follow later.
3425 * Many fixes in the autoconf-script
3426 * Collection/Museum scripts have been added under contrib/museum
3427 * collectd may now be started in unprivileged mode, though ping
3428 statistics will not work.
3430 2005-07-17, Version 1.5.1:
3431 * Diskstats-RRDs now use major/minor for naming. Some systems have
3432 weird strings as disk-names..
3434 2005-07-17, Version 1.5:
3435 * A new module, diskstats, has been added. It collects information
3436 about the disks and partitions.
3438 2005-07-11, Version 1.4.2:
3439 * The meminfo module has been changed to work with more platforms
3440 and/or kernel versions.
3442 2005-07-10, Version 1.4.1: Correct traffic stats
3443 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3444 forgot to correct when I changed that module.
3446 2005-07-09, Version 1.4: More traffic stats
3447 * Traffic is now collected for all interfaces that can be found
3448 * Temperature-statistics are read from lm-sensors if available
3450 2005-07-08, Version 1.3: CPU stats
3451 * Collecting CPU statistics now
3453 2005-07-12, Version 1.2: Using syslog
3454 * collectd is now using the syslog facility to report errors, warnings
3456 * The default directory is now /var/db/collectd
3458 2005-07-10, Version 1.1: Minor changes
3459 * Nothing really useful to say ;)
3461 2005-07-09, Version 1.0: Initial Version
3462 * The following modules are provided:
