2619 Bruno Prémont for finding this problem.
2620 * bind plugin: Fix collection of the cached RR sets. The number of RR
2621 sets currently in the cache was collected as a counter value, which
2622 is nonsense. Thanks to Bruno Prémont for implementing this.

2668 MacEachern for the patch.
2669 * curl plugin: This new plugin can be used to read web pages and parse
2670 them using the same mechanism that's used in the tail plugin.
2671 * dbi plugin: This new plugin allows you to connect to a variety of
2672 relational databases and use SQL to gather custom statistics from
2673 it. It is similar to the already existing PostgreSQL plugin but uses
2674 libdbi to communicate with the database(s).
2675 * interface plugin: Use the ignorelist framework when selecting /
2676 ignoring interfaces. This allows one to use regular expressions to
2677 select interfaces, too.

2703 been added. Portability fixes.
2704 * rrdcached plugin: This new plugin uses the (still in development)
2705 RRD accelerator daemon, rrdcached. This daemon works very similar to
2706 the original rrdtool plugin of collectd, but adds some more nice
2708 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
2711 2009-05-09, Version 4.5.4
2712 * Build system, various plugins: Many build fixes for FreeBSD,
2713 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2714 for many fixes and providing a build system for many platforms,
2715 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2716 providing an OpenBSD system.
2717 * collectd: Fix a potential race condition when creating directories.
2718 * battery plugin: Don't complain about a missing directory every
2720 * dns plugin: Slight portability fixes.
2721 * exec plugin: Allow executed programs to close STDERR. Thanks to
2722 Thorsten von Eicken for reporting this problem.
2723 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
2724 Tomasz Pala for the patch.
2725 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2727 * rrdtool plugin: Fix a possible race condition: If the network plugin
2728 is initialized and dispatches a value before the rrdtool plugin is
2729 initialized, the daemon may crash.
2730 * memory plugin: Fix a potential problem under Solaris.
2732 2009-02-22, Version 4.5.3
2733 * build system: The check for libupsclient even when `pkg-config' is
2735 * collectd: Fix error handling in the global cache.
2736 * Collectd::Unixsock: Error handling has been improved.
2737 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
2739 * ipmi plugin: Fix an off-by-one error which could cause segmentation
2740 faults. Thanks to Peter Holik for his patch.
2741 * tcpconns plugin: An endianness problem has been fixed in the *BSD
2742 code. Thanks to "thated" for reporting this.
2744 2009-01-02, Version 4.5.2
2745 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2746 file may be in both locations, especially when the database was
2747 installed in a non-standard path. Thanks to Dusty Doris for
2749 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2750 Solaris, in the configure script automatically.
2751 * build system, tcpconns plugin: Check for `kvm_nlist' and
2752 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2753 library with similar functions to the BSD variant, but doesn't
2754 provide these necessary functions.
2755 * collectd.conf(5): Various fixes and clarifications.
2756 * collectd: Remove a GNUism (unnamed unions), thus improving
2758 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
2759 This solves portability problems, especially for Solaris.
2760 * dns plugin: Fix a portability problem with NetBSD.
2761 * filecount plugin: Fix an off-by-one error. This error may cause a
2763 * network plugin: Fix the handling of `type' in the network protocol.
2764 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2765 much larger buffer. This caused the `type' to be transferred much
2766 more often than necessary. In some cases, e. g. the `cpu' and
2767 `cpufreq' plugins being used at the same time, data may be corrupted
2768 in those files. Thanks to Bruno Prémont for debugging and reporting
2770 * processes plugin: Fix a possible segmentation fault when specifying
2771 invalid configuration options.
2772 * unixsock plugin: Make sure the initialization function is run only
2773 once. This resolves a file descriptor leak under systems which run
2774 the initialization more than once, such as Solaris.
2776 2008-10-16, Version 4.5.1
2777 * build system: Change `--enable-<plugin>' to abort with an error if
2778 dependencies are not met. Thanks to Bruno Prémont for the patch.
2779 Also, the poisoning of various string functions has been restricted
2781 * collectd: Fix a memory leak in the global value cache. With every
2782 *missing* value a couple of bytes would be leaked. Another memory
2783 leak in the configuration handling code has been fixed. Thanks to
2784 Niraj Tolia for reporting these issues.
2785 * collectd: Fix an off-by-one error in the ignorelist functionality.
2786 When using regular expressions, the last character would be missing,
2787 possibly matching differently from what one would expect.
2788 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2790 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2791 Linzberger for reporting the bug.
2792 * iptables plugin: Fix an off-by-one error. If a string was just one
2793 character too long, it was truncated instead of reporting an error.
2794 * network plugin: Fix a memory leak in the configuration handling
2795 code. Thanks to Niraj Tolia for reporting this issue.
2796 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2797 * postgresql plugin: Don't reopen connection during reinitialization.
2798 This fixes a bug under Solaris and potentially other platforms.
2799 Missing calls to `PQclear' have been added, too. This fixes memory
2800 leaks. Thanks to ``Admin'' for reporting these bugs.
2801 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2803 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2804 problems with some `libc's. Thanks to Matthias Lay for reporting the
2807 2008-09-04, Version 4.5.0
2808 * collectd: Added the ability to flush certain identifiers.
2809 * collectd: The concept of `notification meta data' has been
2811 * filecount plugin: The new filecount plugin counts the number of
2812 files in a directory and its subdirectories.
2813 * ipmi plugin: Sensor names have been changed to ensure unique names.
2814 Notifications upon added and removed sensors can now be generated.
2815 * notify_desktop plugin: This new plugin sends notifications to the
2816 X desktop using the structure defined in the `Desktop Notification
2818 * notify_email plugin: This new plugin sends out notifications via
2819 email, using the `esmtp' library.
2820 * onewire plugin: The new experimental(!) onewire plugin reads values,
2821 such as temperatures, from sensors connected to the computer via the
2823 * perl plugin: Improved synchronized access to internal data structures
2824 and fixed a possible dead-lock.
2825 * perl plugin: Added the ability to flush certain identifiers and marked
2826 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
2828 * perl plugin: Added the ability to configure Perl plugins.
2829 * postgresql plugin: The new postgresql plugin collects statistics
2830 about or from a PostgreSQL database.
2831 * processes plugin: The `ProcessMatch' option has been added.
2832 * rrdtool plugin: Implement throttling of the `update queue' to lessen
2834 * tcpconns plugin: This plugin has been ported to OpenBSD.
2835 * thermal plugin: The new thermal plugin collects system temperatures
2836 using Linux ACPI thermal zone data.
2838 2009-01-02, Version 4.4.5
2839 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2840 file may be in both locations, especially when the database was
2841 installed in a non-standard path. Thanks to Dusty Doris for
2843 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2844 Solaris, in the configure script automatically.
2845 * collectd.conf(5): Various fixes and clarifications.
2846 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
2847 portability problems, especially for Solaris.
2848 * dns plugin: Fix a portability problem with NetBSD.
2849 * network plugin: Fix the handling of `type' in the network protocol.
2850 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2851 much larger buffer. This caused the `type' to be transferred much
2852 more often than necessary. In some cases, e. g. the `cpu' and
2853 `cpufreq' plugins being used at the same time, data may be corrupted
2854 in those files. Thanks to Bruno Prémont for debugging and reporting
2856 * unixsock plugin: Make sure the initialization function is run only
2857 once. This resolves a file descriptor leak under systems which run
2858 the initialization more than once, such as Solaris.
2860 2008-10-16, Version 4.4.4
2861 * build system: Change `--enable-<plugin>' to abort with an error if
2862 dependencies are not met. Thanks to Bruno Prémont for the patch.
2863 Also, the poisoning of various string functions has been restricted
2865 * collectd: Fix a memory leak in the global value cache. With every
2866 *missing* value a couple of bytes would be leaked. Another memory
2867 leak in the configuration handling code has been fixed. Thanks to
2868 Niraj Tolia for reporting these issues.
2869 * collectd: Fix an off-by-one error in the ignorelist functionality.
2870 When using regular expressions, the last character would be missing,
2871 possibly matching differently from what one would expect.
2872 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2874 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2875 Linzberger for reporting the bug.
2876 * network plugin: Fix a memory leak in the configuration handling
2877 code. Thanks to Niraj Tolia for reporting this issue.
2878 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2879 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2880 problems with some `libc's. Thanks to Matthias Lay for reporting the
2883 2008-09-01, Version 4.4.3
2884 * collectd: Fix a memory leak in the threshold checking code.
2885 * memcached plugin: Fix a too short timeout and a related file
2887 * memory plugin: A typo in the libstatgrab code has been fixed.
2888 * snmp plugin: Fix a possible memory leak.
2890 2008-07-15, Version 4.4.2
2891 * build system: Use pkg-config to detect the upsclient library.
2892 * collectd: Try even harder to determine the endianness of the
2893 architecture collectd is being built on.
2894 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
2896 * dns plugin: Fix compilation errors with BIND versions 19991001
2898 * network plugin: Bugfix in the init routine: The init function
2899 cleared a buffer regardless of its contents. This could lead to lost
2900 values under Solaris.
2901 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
2902 * vserver plugin: Remove usage of the thread-unsafe `readdir'
2904 * wireless plugin: Work around incorrect noise and power values
2905 returned by some broken drivers.
2907 2008-06-03, Version 4.4.1
2908 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
2909 to kyrone for reporting this.
2910 * collectd: Fixed min/max output in notifications generated by
2912 * collectd-nagios: Fix the protocol used to communicate with the
2914 * perl plugin: Fail noisily, but don't shutdown the daemon, if
2915 initialization has errors. An issue with Perl 5.10 has been fixed.
2916 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
2917 René Rebe and Siegmund Gorr for reporting this.
2919 2008-05-06, Version 4.4.0
2920 * collectd: Internal code cleanups.
2921 * collectd: Added support for a `Flush' command in the unixsock and
2922 exec plugins. This command can be used to force a plugin (or all) to
2923 flush its values to disk.
2924 * collectd: Thresholds can now be configured to apply to one data
2925 source only, making it possible to configure different thresholds
2926 for each data source.
2927 * apache, nginx plugins: Added the possibility to disable host and/or
2929 * ascent plugin: The new ascent plugin reads and parses the statistics
2930 page of an Ascent server.
2931 * cpu plugin: Support for the statgrab library has been added.

2936 sensor values via IPMI, the intelligent platform management
2938 * iptables plugin: The iptc library that is used by the iptables
2939 plugin has been added to the distribution, because it is not
2940 provided by all distributions and removed from at least one.
2941 * powerdns plugin: The new powerdns plugin reads statistics from an
2942 authoritative or a recursing PowerDNS name server.
2943 * rrdtool plugin: The size of the files generated with the default
2944 configuration has been decreased.
2945 * tail plugin: The new tail plugin can be used to gather statistics by
2946 continuously reading from log files.
2947 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
2948 TeamSpeak2 server and collects statistics about the number of users
2949 and number of channels.
2950 * users plugin: Support for the statgrab library has been added.
2951 * vmem plugin: The new vmem plugin collects very detailed statistics
2952 about the virtual memory subsystem of Linux.
2954 2008-08-30, Version 4.3.4
2955 * Build system: Improved detection of and linking with the statgrab
2957 * collectd: Portability fixes, especially to determine endianness more
2959 * Various plugins: Fix format strings.

2961 again has been applied.
2962 * memcached plugin: Fix a too short timeout and a related file
2964 * memory plugin: A typo in the libstatgrab code has been fixed.
2965 * network plugin: A fix in the initialization function solves problems
2967 * nginx plugin: A thread-unsafe function has been replaced.

2973 * build system: Improved detection of several libraries, especially if
2974 they are in non-standard paths.
2975 * build system: Portability fixes: Automatically define "_REENTRANT"
2976 if the libc expects it.
2977 * collectd: Error and warning messages have been improved.
2978 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
2980 * apache plugin: Allocate new memory when reading a webpage instead of
2981 using a buffer of static size.
2982 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
2984 * hddtemp plugin: Error and warning messages have been improved.
2985 * sensors plugin: Fix sensor collection for some chip types.
2987 2008-03-29, Version 4.3.2
2988 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
2989 `Persist' threshold options.
2990 * collectd: Fix handling of missing values in the global value cache.
2991 * collectd: Improved error messages when parsing the configuration.
2992 * sensors plugin: Fix temperature collection with libsensors4.
2993 * unixsock plugin: Fix mixed input and output operation on streams.
2994 * wireless plugin: Fix reading noise value.
2996 2008-03-05, Version 4.3.1
2997 * exec plugin: Set supplementary group IDs.
2999 + Use `memcpy' when constructing/parsing a package to avoid
3000 alignment problems on weird architectures, such as Sparc.
3001 + Translate doubles to/from the x86 byte representation to ensure
3002 cross-platform compatibility.
3003 * ping plugin: Correct the handling of the `TTL' setting.
3004 * swap plugin: Reapply a patch for Solaris.
3005 * tcpconns plugin: Portability improvements.
3007 2008-02-18, Version 4.3.0
3008 * collectd: Notifications have been added to the daemon. Notifications
3009 are status messages that may be associated with a data instance.
3010 * collectd: Threshold checking has been added to the daemon. This
3011 means that you can configure threshold values for each data
3012 instance. If this threshold is exceeded a notification will be
3014 * collectd: The new `FQDNLookup' option tells the daemon to use the
3015 full qualified domain name as the hostname, not just the host part
3016 es returned by `gethostname(2)'.
3017 * collectd: Support for more than one `TypesDB' file has been added.
3018 This is useful when one such file is included in a package but one
3019 wants to add custom type definitions.
3020 * collectd: The `Include' config option has been expanded to handle
3021 entire directories and shell wildcards.
3022 * collectdmon: The new `collectdmon' binary detects when collectd
3023 terminates and automatically restarts it again.
3024 * csv plugin: The CSV plugin is now able to store counter values as a
3025 rate, using the `StoreRates' configuration option.
3026 * exec plugin: Handling of notifications has been added and the
3027 ability to pass arguments to the executed programs has been added.
3028 * hddtemp plugin: The new `TranslateDevicename' option lets you
3029 disable the translation from device names to major-minor-numbers.
3030 * logfile plugin: Handling of notifications has been added.
3031 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3032 domain name lookups in this plugin.
3033 * perl plugin: Many internal changes added support for handling multiple
3034 threads making the plugin reasonably usable inside collectd. The API has
3035 been extended to support notifications and export global variables to
3036 Perl plugins; callbacks now have to be identified by name rather than a
3037 pointer to a subroutine. The plugin is no longer experimental.
3038 * uuid plugin: The new UUID plugin sets the hostname to an unique
3039 identifier for this host. This is meant for setups where each client
3040 may migrate to another physical host, possibly going through one or
3041 more name changes in the process. Thanks to Richard Jones from
3042 Red Hat's Emerging Technology group for this plugin.
3043 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3044 CPU, disk and network statistics about guest systems on the same
3045 physical server. Thanks to Richard Jones from Red Hat's Emerging
3046 Technology group for this plugin.
3048 2008-04-22, Version 4.2.7
3049 * build system: Improved detection of several libraries, especially if
3050 they are in non-standard paths.
3051 * build system: Portability fixes: Automatically define "_REENTRANT"
3052 if the libc expects it.
3053 * collectd: Error and warning messages have been improved.
3054 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3056 * apache plugin: Allocate new memory when reading a webpage instead of
3057 using a buffer of static size.
3058 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3060 * hddtemp plugin: Error and warning messages have been improved.
3061 * sensors plugin: Fix sensor collection for some chip types.

3066 * unixsock plugin: Fix mixed input and output operation on streams.
3067 * wireless plugin: Fix reading noise value.
3069 2008-03-04, Version 4.2.5
3070 * apache plugin: Improved initialization and error messages.
3071 * exec plugin: Set supplementary group IDs.
3073 + Create separate threads for reading from the socket and parsing
3074 and dispatching incoming packets. Versions prior to this may have
3075 problems in high-load situations, where the socket receive buffers
3076 overflows, resulting in gaps in the data.
3077 + Use `memcpy' when constructing/parsing a package to avoid
3078 alignment problems on weird architectures, such as Sparc.
3079 + Translate doubles to/from the x86 byte representation to ensure
3080 cross-platform compatibility.
3081 * ping plugin: Correct the handling of the `TTL' setting.
3082 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3083 * swap plugin: Reapply a patch for Solaris.
3084 * tcpconns plugin: Portability improvements.
3086 2008-01-21, Version 4.2.4
3087 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3088 the permission on the socket as documented in the manpage. Thanks to
3089 Evgeny Chukreev for fixing this issue.
3090 * collectd: The documentation has been improved.
3092 2007-12-28, Version 4.2.3
3093 * sensors plugin: Updated the plugin to build and work with version 3
3094 of the libsensors library.
3096 2007-12-15, Version 4.2.2
3097 * nginx plugin: Incorrect comparison of strings lead to a segfault
3098 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3100 * logfile plugin: The config option `Timestamp' was handled
3101 incorrectly and basically always active. Thanks to Luke Heberling
3104 2007-11-08, Version 4.2.1
3105 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3106 enabled on the host.
3107 * snmp plugin: Fix a memory leak.
3109 2007-10-27, Version 4.2.0
3110 * collectd: The new config option `Include' lets you include other
3111 configfiles and thus split up your config into smaller parts. This
3112 may be especially interesting for the snmp plugin to keep the data
3113 definitions separate from the host definitions.
3114 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3115 (number of connections, octets and packets for each service and
3116 destination). Thanks to Sebastian Harl for this plugin.
3117 * memcached plugin: The new `memcached' plugin connects to a memcached
3118 daemon process and collects statistics of this distributed caching
3119 system. Thanks to Antony Dovgal for contributing this plugin.
3120 * nginx plugin: The new `nginx' plugin reads the status page of an
3121 nginx daemon and saves the handled connections and requests.
3122 * perl plugin: Many changes, including the added `EnableDebugger'
3123 config option which lets you debug your Perl plugins more easily.
3124 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3125 be more thread-safe otherwise by locking calls to the library.
3126 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3127 correct the values returned by SNMP-agents. If a <data> block is
3128 defined as `table' the instance is now optional. The sequence number
3129 is used as the type-instance in this case. The new `InstancePrefix'
3130 option allows to add arbitrary prefixes to the type-instance.
3131 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3132 certain TCP connections and what state they're in. This can be used
3133 to see how many connections your FTP server has to handle or how
3134 many outgoing connections your mailserver has open.
3136 2008-01-11, Version 4.1.6
3137 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3138 the permission on the socket as documented in the manpage. Thanks to
3139 Evgeny Chukreev for fixing this issue.
3140 * collectd: The documentation has been improved.
3142 2007-12-27, Version 4.1.5
3143 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

3146 of the libsensors library.
3148 2007-11-08, Version 4.1.4
3149 * Build system: Improve detection of the rrd library, especially if
3150 it's in a non-standard location.
3151 * Build system: A bug when parsing the argument for
3152 `--with-libnetsnmp' has been fixed.
3153 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3154 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3155 a deadlock or delay when shutting down the daemon.
3156 * snmp plugin: Fix a memory leak.
3158 2007-10-24, Version 4.1.3
3159 * collectd: A build issue under Solaris has been resolved by renaming
3161 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3162 be more thread-safe otherwise by locking calls to the library.
3164 2007-09-28, Version 4.1.2
3165 * apcups plugin: Fix reporting of the `load percent' data.
3166 * wireless plugin: Correct the handling of cards returning signal and
3167 noise quality as percentage.
3168 * perl plugin: Fix a possible buffer overflow in get_module_name().
3169 * build system: Further improve the detection of libraries.
3170 * netlink plugin: Build issues under some older versions of the Linux
3171 includes (i. e. Debian Sarge) have been fixed.
3172 * snmp plugin: Fix a potential segfault when a host times out. Add
3173 support for the `timeticks' type.
3175 2007-09-12, Version 4.1.1
3176 * Build system: The detection of `libnetlink' has been improved.
3177 * collectd: The documentation has been fixed in numerous places.
3178 * exec plugin: Setting the group under which to run a program has been
3180 * collectd: The `sstrerror' function was improved to work correctly
3181 with the broken GNU version of `strerror_r'.
3182 * collectd: Write an error message to STDERR when loading of a plugin
3184 * apcups plugin: Fix the `types' used to submit the values: They still
3185 has an `apcups_' prefix which doesn't work anymore.
3186 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3187 whatever the client thinks is `now'..
3189 2007-09-01, Version 4.1.0
3190 * Build system: The build system has been changed to automatically
3191 disable all plugins, which are missing dependencies. The dependency
3192 checking has been removed from the plugins themselves to remove
3194 * Flexible interval: The interval of collected data is now sent along
3195 with the data itself over the network, so that the interval-settings
3196 of server and clients no longer needs to match.
3197 * netlink plugin: The new `netlink' plugin connects to the Linux
3198 kernel using a netlink socket and uses it to query information about
3199 interfaces, qdiscs and classes.
3200 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3201 to not block data collection.
3202 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3203 network devices, such as switches, routers, thermometers, rack
3204 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3206 * unixsock plugin: Added the `LISTVAL' command.
3207 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3208 of music played with xmms.
3210 2007-09-28, Version 4.0.9
3211 * apcups plugin: Fix reporting of the `load percent' data.
3212 * wireless plugin: Correct the handling of cards returning signal and
3213 noise quality as percentage.
3214 * perl plugin: Fix a possible buffer overflow in get_module_name().
3216 2007-09-12, Version 4.0.8
3217 * collectd: The `sstrerror' function was improved to work correctly
3218 with the broken GNU version of `strerror_r'.
3219 * collectd: Write an error message to STDERR when loading of a plugin
3221 * apcups plugin: Fix the `types' used to submit the values: They still
3222 has an `apcups_' prefix which doesn't work anymore.
3223 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3224 whatever the client thinks is `now'..
3226 2007-08-26, Version 4.0.7
3227 * documentation: Some typos have been fixed and some information has
3229 * build system: Many fixes for detecting libraries in unusual places,
3230 such as on RedHat systems. The affected libraries are `libcurl',
3231 `libmysql', and `libupsclient'.
3232 * network plugin: Allow the `Port' option to be specified as a number
3233 (i. e. without quotes).
3234 * nut plugin: A fix allows linking the nut plugin against
3235 libupsclient, version >= 2.2.0.
3236 * processes plugin: Fix a potential segmentation fault.
3238 2007-07-30, Version 4.0.6
3239 * sensors plugin: Fix the ignorelist functionality: Only the `type
3240 instance' was used to match against the list, but the documentation
3241 told otherwise. This release fixes the code, so it complies with the
3243 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3244 configuration messages will end up in the logging facility.
3245 * conrtib/fedora: The contributed specfile for Fedora has been
3248 2007-07-05, Version 4.0.5
3249 * Portability: More fixes for OpenBSD have been included.
3251 2007-06-24, Version 4.0.4
3252 * cpu plugin: Fixed the Solaris code.
3253 * dns plugin: Fixed a build issue for OpenBSD.
3254 * interface plugin: Fixed the Solaris code.
3255 * load plugin: Fixed the alternative `/proc' Linux code.
3256 * memory plugin: Fixed the Solaris code.
3257 * oconfig: Don't require `-lfl' anymore.
3259 2007-06-19, Version 4.0.3
3260 * cpu plugin: Fix the Darwin / Mac OS X code.
3261 * ping plugin: Use the return value of `getpid', not its address.

3268 they're given in numerically form.
3270 2007-06-07, Version 4.0.1
3271 * iptables plugin: A bug in the configuration routine has been fixed.
3272 Setting a comment in the configfile will no longer cause a
3275 2007-06-03, Version 4.0.0
3276 * collectd: The plugin-infrastructure has been changed to allow for
3277 more types of plugins, namely `write' and `log' plugins.
3278 * collectd: The read-function has been changed to read many plugins in
3279 parallel, using threads. Thus, plugins generally need to use
3280 thread-safe functions from now on.
3281 * collectd: The '-t' command line options allows to perform syntax tests
3282 of the configuration file and exit immediately.
3283 * csv plugin: The new `csv' plugin handles output to `comma separated
3285 * rrdtool plugin: The new `rrdtool' plugin handles output to
3286 RRD-files. Data can be cached to combine multiple updates into one
3287 write to increase IO-performance.
3288 * network plugin: The new `network' plugin handles IO via the network.
3289 It implements a different, much more extensible protocol which can
3290 combine many values in one packet, decreasing the number of UDP-
3291 packets being sent. It can read from and send to the network and
3292 with the appropriate configuration even forward packets to other
3294 * unixsock plugin: The new `unixsock' plugin provides an interface to
3295 communicate with the daemon while it is running. Right now the
3296 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3298 * perl plugin: The new `perl' plugin allows you to write extensions
3299 for collectd in the scripting-language Perl.
3300 * logfile plugin: The new `logfile' plugin writes logmessages to files
3301 or STDOUT or STDERR.
3302 * syslog plugin: The new `syslog' plugin sends logmessages to the
3303 system's syslog daemon.
3304 * entropy plugin: The new `entropy' plugin collects the amount of
3305 entropy currently being available to the system.
3306 * exec plugin: The new `exec' plugin forks child processes and reads
3307 back values provided by the forked processes.
3308 * iptables plugin: The new `iptables' plugin reads counters from
3309 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3311 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3312 to Peter Holik for contributing this plugin.
3313 * nut plugin: The new `nut' plugin connects the upsd of the `network
3314 ups tools' and reads information about the connected UPS.
3315 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3316 connections) field was added by Florent Monbillard.
3317 * collectd-nagios: The new `collectd-nagios' binary queries values
3318 from collectd, parses them and exits according to Nagios-standards.
3319 * manpages: The manpages have been improved a lot.
3321 2007-09-28, Version 3.11.7
3322 * wireless plugin: Correct the handling of cards returning signal and
3323 noise quality as percentage.
3325 2007-08-31, Version 3.11.6
3326 * processes plugin: Fix a potential segmentation fault.
3328 2007-05-29, Version 3.11.5
3329 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3330 * ntpd plugin: Fix a potential buffer overflow.
3331 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3332 were accounted as `zombies'.
3334 2007-04-10, Version 3.11.4
3335 * dns plugin: Change the order of includes to make the plugin compile
3338 2007-03-30, Version 3.11.3
3339 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3340 of the unused `COLLECT_KSTAT'.
3342 2007-02-11, Version 3.11.2
3343 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3344 NULL-pointer may have been passed to `printf' which causes a
3345 segfault with some libcs.
3347 2007-02-10, Version 3.11.1
3348 * df plugin: Some wrong defines have been fixed so the plugin works
3349 under Solaris again.
3350 * dns plugin: The usage of a struct has been fixed to work with
3352 * processes plugin: Some missing defines have been added so the plugin
3353 compiles cleanly under FreeBSD and presumably other UNIXes.
3355 2006-12-22, Version 3.11.0
3356 * collectd: The new command line option `-P' makes it easier for
3357 distributors to change the location of PID-files.
3358 * collectd: The daemon shuts down faster now which makes it easier to
3359 write init.d-scripts for it.
3360 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3361 caused problems every now and then.
3362 * df plugin: New config options allow to ignore certain mountpoints,
3363 filesystem types or devices.
3364 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3365 and interprets it. It collects traffic as well as qtype, opcode and
3367 * email plugin: Sebastian Harl has contributed this plugin which
3368 counts received mails in categories (e. g. ham, spam, virus), spam
3369 score (as given by SpamAssassin) and check types.
3370 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3371 uses `mbmon' to gather information from sensors on the motherboard.
3372 * processes plugin: Collect detailed statistics for configured
3373 processes, that's process and thread count, CPU usage, resident
3374 segment size and pagefaults.
3375 * multimeter plugin: Peter Holik contributed a new plugin which
3376 queries multimeters.
3377 * sensors plugin: Lubos Stanek has put much effort into improving this
3378 plugin, including `extended naming', collection of voltage values
3379 and the possibility to ignore certain values.
3381 2006-12-21, Version 3.10.4
3382 * Max Kellermann has identified a bug in the server routine: When
3383 opening a socket fails the daemon will (re)try opening the socket in
3384 an endless loop, ultimately leading to a `EMFILE' error.
3386 2006-11-04, Version 3.10.3
3387 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3388 ntpd's reply was sent in more than one packet, the buffer size was
3389 calculated incorrectly, resulting in the reading of uninitialized or
3392 2006-11-01, Version 3.10.2
3393 * The sample config file has been improved.
3394 * Errors in the manpages have been corrected.
3395 * The ping-plugin now adds hosts during initialization, not during
3396 startup. This speeds up startup when no network connectivity is
3397 available. Also, the hosts are being added later when the network is
3399 * Improved BSD-support for the df-plugin.
3400 * Fixed syntax errors in the swap-plugin for Mac OS X.
3401 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3403 * Don't disable the mysql-plugin if connecting to the database fails
3404 during initialization. Instead, try again in increasing intervals.
3406 2006-07-19, Version 3.10.1
3407 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3408 the apcups cannot be reached, unconnected sockets will pile up and
3409 eventually lead to `Too many open files' errors.
3411 2006-07-09, Version 3.10.0
3412 * The `disk' plugin has been ported to Darwin.
3413 * The `battery' plugin should work on many Apple computers now.
3414 * The `traffic' plugin can now ignore certain interfaces. Also,
3415 statistics for sent/received packets and errors have been added.
3416 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3417 to Anthony Gialluca for contributing this plugin and providing me
3418 with a test environment :)
3419 * A plugin for monitoring an NTP instance and the local clock drift
3422 2006-06-25, Version 3.9.4
3423 * The Solaris code in the `swap' plugin has been changed to reflect
3424 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3426 * The debugging system has been fixed to work with the Sun libc.
3427 * When built without librrd the variable `operating_mode' could be
3428 uninitialized. Thanks to David Elliot for reporting the bug.
3430 2006-06-01, Version 3.9.3
3431 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3432 operating systems also profit from the changes, but I wasn't able to
3434 * Changed the build system to find the netinet-includes under FreeBSD
3435 and therefore successfully build the `liboping' library there.
3437 2006-05-09, Version 3.9.2
3438 * Applied a patch to the `liboping' library. Due to a bug in the
3439 sequence checking the `ping' plugin stopped working after
3440 approximately 7.6 days.
3442 2006-05-09, Version 3.8.5
3443 * Applied a patch to the `liboping' library. Due to a bug in the
3444 sequence checking the `ping' plugin stopped working after
3445 approximately 7.6 days.
3447 2006-04-21, Version 3.9.1
3448 * Build issues with Solaris and possible other architectures have been
3450 * Problems when building the `apache'-plugin without `libcurl' have
3452 * A bug in the `ping' plugin has been fixed. Sorry folks.
3454 2006-04-02, Version 3.9.0
3455 * A plugin to monitor the Apache webserver has been added.
3456 <http://httpd.apache.org/>
3457 * A plugin to collect statistics about virtual servers using VServer.
3458 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3460 * A plugin for wireless LAN cards has been added. It monitors signal
3461 strength, link quality and noise ratio..
3462 * A plugin for Apple hardware sensors has been added.
3463 * An option to compile collectd with different `step' and `heartbeat'
3464 settings has been added. The size of RRAs is no longer static but
3465 calculated based on the settings for `step' and `width'.
3466 * The `ping' plugin can now be configured to use a certain TTL.
3467 * A plugin to monitor the hardware sensors of Apple computers has been
3469 * The plugins `cpu', `memory', `processes' and `traffic' have been
3470 ported to Mach/Darwin (Mac OS X).
3471 * The `log mode' has been contributed by Christophe Kalt. It writes
3472 the data into text files rather than RRD files.
3474 2006-04-09, Version 3.8.4
3475 * Applied patch by Vincent Stehlé which improves the disk-name
3476 resolution in the `hddtemp' plugin for Linux systems.
3478 2006-04-02, Version 3.8.3
3479 * Applied a patch by James Byers: The MySQL plugin was not working
3480 with MySQL 5.0.2 or later.
3482 2006-03-14, Version 3.8.2
3483 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3484 the GNU libc, because it points to `/etc/fstab' rather than
3487 2006-03-13, Version 3.8.1
3488 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3489 * Fixes in the debian `postinst' and `init.d' scripts.
3491 2006-03-09, Version 3.8.0
3492 * The `ping' plugin no longer uses `libping' but a self written
3493 library named `liboping'. With this library it's possible to ping
3494 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3496 2006-02-18, Version 3.7.2
3497 * A simple bug in the `battery' plugin has been fixed. It should now
3498 work with ACPI based batteries as well. Thanks to Sebastian for
3500 * Fixing a bug that prevented collectd to be built without librrd.
3501 Thanks to Werner Heuser for reporting it.
3503 2006-02-04, Version 3.7.1
3504 * The new network code has been improved to build with older versions
3506 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3507 to Tommie Gannert for this patch.
3509 2006-01-30, Version 3.7.0
3510 * The `battery' plugin has been added. It collects information about
3512 * The MySQL plugin has been improved: It now writes two more RRD
3513 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3514 * The `cpufreq' plugin now reads another file since the file it did
3515 read so far causes much overhead in the kernel. Also, you need root
3516 to read the old file, but not to read the new one.
3517 * The `hddtemp' plugin can now be configured to connect to another
3518 address and/or port than localhost.
3519 * The `df' plugin now prefers `statvfs' over `statfs'.
3520 * The network code has been rewritten. collectd now supports unicast
3521 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3522 be set in the configfile.
3524 2006-01-24, Version 3.6.2
3525 * Due to a bug in the configfile handling collectd wouldn't start in
3526 client mode. This released fixes this.
3528 2006-01-20, Version 3.6.1
3529 * Due to a bug in `configure.in' all modules and the binary were
3530 linked against `libmysqlclient'. This issue is solved by this
3533 2006-01-17, Version 3.6.0
3534 * A config file has been added. This allows for loading only specific
3536 * A `df' plugin has been added.
3537 * A `mysql' plugin has been added.
3538 * The `ping' plugin doesn't entirely give up hope when a socket error
3539 occurred, but will back of and increase the intervals between tries.
3541 2006-01-21, Version 3.5.2
3542 * Fixed yet another bug in the signal handling.. Stupid typo..
3543 * Improved the ping plugin to not give up on socket errors (backport
3546 2005-12-18, Version 3.5.1
3547 * The PID-file is now deleted correctly when shutting down the daemon.
3548 * SIGINT and SIGTERM are now handled correctly.
3550 2005-12-16, Version 3.5.0 (Revision 326)
3551 * A bug in the `load' module under Solaris has been fixed.
3552 * The `users' module has been contributed by Sebastian Harl. It counts
3553 currently logged in users.
3554 * The CPU module now works under FreeBSD without the use of
3555 `libstatgrab', however SMP support is missing.
3556 * The default directories for the RRD files and the PID file now
3557 depend on the compile time setting of `localstatedir'.
3559 2005-11-15, Version 3.4.0 (Revision 236)
3560 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3561 from gentoo's bugzilla for writing the patch.
3562 * The build dependency for librrd has been removed. Binaries built
3563 without librrd are client-only and will multicast their value as
3564 with the `-c' argument.
3565 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3566 * The newly introduced `-f' switch prevents daemon initialization
3567 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3568 Barcellos for this patch.
3570 2005-11-04, Version 3.3.0 (Revision 216)
3571 * New modules have been added:
3572 - `serial', for monitoring traffic on the serial interfaces
3573 - `nfs', for graphing NFS procedure calls
3574 - `tape', traffic from/to tape devices
3575 * The memory.rrd now accepts more than 4Gig of memory.
3577 2005-10-26, Version 3.2.0 (Revision 200)
3578 * Support for graphing the processes has been added (thanks to Lyonel
3580 * If reading from hddtemp fails collectd will increase the time
3581 between polls up to one day.
3582 * The init.d files have been improved.
3583 * Problems with the spec file have been fixed.
3585 2005-10-16, Version 3.1.0 (Revision 194)
3586 * Added the `setsid' syscall to the startup code.
3587 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3589 2005-09-30, Version 3.0.0 (Revision 184)
3590 * The ability to send/receive data to/from the network (think
3591 multicast) has been added.
3592 * Modules have been split up into shared libraries can be loaded at
3593 runtime. The biggest advantage is that the core program doesn't need
3594 to be linked against an external library.
3595 * A patch by George Kargiotakis has been applied: It fixes the sensors
3596 behaviour then more than one sensor is being queried.
3598 2005-09-16, Version 2.1.0 (Revision 172)
3599 * A module for swap statistics has been added.
3601 2005-09-09, Version 2.0.0 (Revision 135)
3602 * Filenames can no longer be configured at program startup. The only
3603 options as of this version are the directory and ping hosts.
3604 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3605 Soft-IRQ statistics are added to `System'.
3606 * Diskstats now collect read and write bytes, not sectors.
3607 * Ping statistics can now be collected for more than one host. There
3608 is no default any more: If no host is given no host will be pinged.
3609 * A self-written patch for libping has been applied so it builds
3612 2005-09-01, Version 1.8.1 (Revision 123)
3613 * Much improved configure-script: libraries and features may now be
3615 * More detailed warnings/error messages when RRD update fails.
3617 2005-08-29, Version 1.8.0:
3618 * Support for collecting disk statistics under Solaris.
3620 2005-08-25, Version 1.7.0:
3621 * Support for libstatgrab[1] for load, memory usage and network
3622 traffic. CPU- and disk-usage are not (yet) supported, since
3623 libstatgrab returns insufficient information. I will contact the
3625 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3626 aren't necessarily counted linear which is now handled correctly.
3627 [1]: http://www.i-scream.org/libstatgrab/
3629 2005-08-21, Version 1.6.0:
3630 * Basic support for Solaris: System load and cpu-usage can be
3631 collected under Solaris, too. Other stats will follow later.
3632 * Many fixes in the autoconf-script
3633 * Collection/Museum scripts have been added under contrib/museum
3634 * collectd may now be started in unprivileged mode, though ping
3635 statistics will not work.
3637 2005-07-17, Version 1.5.1:
3638 * Diskstats-RRDs now use major/minor for naming. Some systems have
3639 weird strings as disk-names..
3641 2005-07-17, Version 1.5:
3642 * A new module, diskstats, has been added. It collects information
3643 about the disks and partitions.
3645 2005-07-11, Version 1.4.2:
3646 * The meminfo module has been changed to work with more platforms
3647 and/or kernel versions.
3649 2005-07-10, Version 1.4.1: Correct traffic stats
3650 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3651 forgot to correct when I changed that module.
3653 2005-07-09, Version 1.4: More traffic stats
3654 * Traffic is now collected for all interfaces that can be found
3655 * Temperature-statistics are read from lm-sensors if available
3657 2005-07-08, Version 1.3: CPU stats
3658 * Collecting CPU statistics now
3660 2005-07-12, Version 1.2: Using syslog
3661 * collectd is now using the syslog facility to report errors, warnings
3663 * The default directory is now /var/db/collectd
3665 2005-07-10, Version 1.1: Minor changes
3666 * Nothing really useful to say ;)
3668 2005-07-09, Version 1.0: Initial Version
3669 * The following modules are provided:
