2674 * empty_counter match: The new Empty Counter match matches value
2675 lists, where at least one data source is of type COUNTER and the
2676 counter value of all counter data sources is zero.
2678 2009-12-18, Version 4.7.5
2679 * Build system, java plugin: Don't use “find -L” to search for Java
2680 headers, because it's a GNU extension.
2681 * Build system: Support for parallel builds has been improved. Thanks
2682 Sebastian Harl and Stefan Völkel for looking into this.
2683 * collectd: Print error messages to STDERR if no log plugin has been
2685 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
2686 * network plugin: The license has been changed to LGPL 2.1.

2691 containing control characters are now interpreted as hex-strings.
2692 * unixsock plugin: A memory leak in the LISTVAL command has been
2693 fixed. Thanks to Ben Knight for his patch.
2695 2009-10-03, Version 4.7.4
2696 * Build system: Issues when building the iptables plugin have been
2698 * exec plugin: Clear the signal block mask before calling exec(2).
2699 * perl plugin: Declare the “environ” variable. This solves build
2700 issues on some platforms.
2701 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
2702 Andrés J. Díaz for the patch.
2703 * unixsock plugin: Fix a (well hidden) race condition related to file
2704 descriptor handling.
2706 2009-09-13, Version 4.7.3
2707 * collectd: Fix a possible but very rare invalid “free” in the caching
2708 code. Thanks to Sebastian Harl for the patch.
2709 * collectd: Remove old values when a cache entry is marked as missing.
2710 This way the “GETVAL” command of the UnixSock plugin doesn't return
2711 old, no longer valid values when this happens. Thanks to Andrés J.
2713 * collectd: The “plugin_unregister_read” function has been fixed.
2714 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2715 to follow redirects. Thanks to Joey Hess for reporting this bug.

2722 is linked with the shipped library, too.
2723 * java plugin: Delay creating the JVM until after the daemon has
2724 forked. The JVM internally creates threads that are lost when
2725 forking. This means that Java-based plugins are now configured
2726 during the init-phase, i. e. later than other plugins.
2727 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2728 to Alan Pevec for the patch.
2729 * network plugin: Fix the handling of the “CacheFlush” option: The

2751 details have been added to the configuration summary. Support for
2752 libtool 2.2 has been added.
2753 * collectd: Two bugs with the threshold checking have been fixed. The
2754 first one prevented thresholds to be checked at all, the second one
2755 caused wrong behavior with the persistency option. Thanks to Andrés
2756 J. Díaz for fixing these problems.
2757 * collectd: Handling of the `Include' configuration option has been
2759 * rrdtool plugin: Make sure initialization is run only once. This
2760 resolves problems under Solaris and potentially other systems.
2761 Thanks to Amit Gupta for reporting this bug.
2762 * java plugin: Make it possible to use dots ('.') instead of slashes
2763 ('/') as the class separator. Thanks to Randy Rizun for pointing

2779 multicast traffic from Ganglia's gmond daemon.
2780 * java plugin: The new java plugin exports the collectd API to Java,
2781 making it possible to write extensions to collectd in Java.
2782 * memcachec plugin: The new memcachec plugin queries data from a
2783 memcached daemon and parses it similar to the cURL plugin. Thanks to
2784 Doug MacEachern for the initial code.

2800 * table plugin: The new Table plugin provides parsing for table-like
2801 structured files, such as many files beneath /proc.
2802 * ted plugin: The new TED plugin reads power consumption measurements
2803 from “The Energy Detective” (TED). Thanks to Eric Reed for this
2805 * onewire plugin: The new `Interval' option allows collecting
2806 information from OneWire sensors at arbitrary intervals.
2807 * ping plugin: Support for collecting the drop rate and standard
2808 deviation of round-trip times has been added.
2809 * uptime plugin: The new uptime plugin can collect the server's
2810 uptime. Thanks to Marco Chiappero for the patch.
2812 2009-09-10, Version 4.6.5
2813 * collectd: Remove old values when a cache entry is marked as missing.
2814 This way the “GETVAL” command of the UnixSock plugin doesn't return

2842 * Build system, various plugins: Many build fixes for FreeBSD,
2843 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2844 for many fixes and providing a build system for many platforms,
2845 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2846 providing an OpenBSD system.
2847 * collectd: Two bugs with the threshold checking have been fixed. The
2848 first one prevented thresholds to be checked at all, the second one
2849 caused wrong behavior with the persistency option. Thanks to Andrés
2850 J. Díaz for fixing these problems.
2851 * collectd: Handling of the `Include' configuration option has been

2867 * filter subsystem: Allow `Chains' without default targets.
2868 * liboping: A patch to comply with strict aliasing rules has been
2870 * timediff match: Fix a typo: The match was registered with a wrong
2871 name which prevented this match to be used as documented. Thanks to
2872 Bruno Prémont for finding this problem.
2873 * bind plugin: Fix collection of the cached RR sets. The number of RR
2874 sets currently in the cache was collected as a counter value, which
2875 is nonsense. Thanks to Bruno Prémont for implementing this.
2876 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2877 primarily BSDs, don't take it well and crash.
2878 * oracle plugin: Portability to 64 bit systems has been improved.
2879 * postgresql plugin: The default configuration has been improved.
2880 * rrdtool plugin: Fix a possible race condition: If the network plugin

2891 faults. Thanks to Peter Holik for his patch.
2893 2009-02-16, Version 4.6.0
2894 * collectd: Added the `filter chain' infrastructure, which allows the
2895 user to use `matches' and `targets' to control value processing.
2896 * collectd: The new `-T' command line argument allows more in-depth
2897 testing of a configuration. Thanks to Doug MacEachern for the patch.
2898 * collectd-nagios: The Nagios integration command has been updated to
2899 use libcollectdclient. The `percentage' aggregation function has
2900 been added. Thanks to Fabian Linzberger for the patch.

2912 statistics, allowing very detailed name server statistics. Thanks to
2913 Bruno Prémont for this plugin.
2914 * cpu plugin: Report `interrupt' separately when using
2915 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
2916 example for native OpenBSD support, has been added. Thanks to Simon
2917 Kuhnle for the patch.
2918 * csv plugin: Make it possible to write values to STDOUT instead of
2919 files. This is meant for testing purposes mostly. The output written
2920 to STDOUT is compatible with the exec plugin. Thanks to Doug
2921 MacEachern for the patch.
2922 * curl plugin: This new plugin can be used to read web pages and parse
2923 them using the same mechanism that's used in the tail plugin.
2924 * dbi plugin: This new plugin allows you to connect to a variety of
2925 relational databases and use SQL to gather custom statistics from
2926 it. It is similar to the already existing PostgreSQL plugin but uses
2927 libdbi to communicate with the database(s).
2928 * interface plugin: Use the ignorelist framework when selecting /
2929 ignoring interfaces. This allows one to use regular expressions to
2930 select interfaces, too.
2931 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2932 Thanks to Bruno Prémont for this patch.
2933 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

2949 allowing plugins to register `matches' and `targets'.
2950 * postgresql plugin: The preferred configuration syntax has been
2951 updated to be in line with the syntax used by the new dbi and oracle
2952 plugins. The compatibility code for the old syntax is present.
2953 Support for the new `Result' blocks and the interval parameter has
2955 * processes plugin: Stacksize and virtual memory usage statistics have
2956 been added. Portability fixes.
2957 * rrdcached plugin: This new plugin uses the (still in development)
2958 RRD accelerator daemon, rrdcached. This daemon works very similar to
2959 the original rrdtool plugin of collectd, but adds some more nice

2978 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2980 * rrdtool plugin: Fix a possible race condition: If the network plugin
2981 is initialized and dispatches a value before the rrdtool plugin is
2982 initialized, the daemon may crash.
2983 * memory plugin: Fix a potential problem under Solaris.
2985 2009-02-22, Version 4.5.3

2995 code. Thanks to "thated" for reporting this.
2997 2009-01-02, Version 4.5.2
2998 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2999 file may be in both locations, especially when the database was
3000 installed in a non-standard path. Thanks to Dusty Doris for
3002 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3003 Solaris, in the configure script automatically.
3004 * build system, tcpconns plugin: Check for `kvm_nlist' and
3005 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3006 library with similar functions to the BSD variant, but doesn't
3007 provide these necessary functions.
3008 * collectd.conf(5): Various fixes and clarifications.
3009 * collectd: Remove a GNUism (unnamed unions), thus improving
3011 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

3014 * filecount plugin: Fix an off-by-one error. This error may cause a
3016 * network plugin: Fix the handling of `type' in the network protocol.
3017 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3018 much larger buffer. This caused the `type' to be transferred much
3019 more often than necessary. In some cases, e. g. the `cpu' and
3020 `cpufreq' plugins being used at the same time, data may be corrupted
3021 in those files. Thanks to Bruno Prémont for debugging and reporting
3023 * processes plugin: Fix a possible segmentation fault when specifying
3024 invalid configuration options.
3025 * unixsock plugin: Make sure the initialization function is run only
3026 once. This resolves a file descriptor leak under systems which run
3027 the initialization more than once, such as Solaris.
3029 2008-10-16, Version 4.5.1
3030 * build system: Change `--enable-<plugin>' to abort with an error if
3031 dependencies are not met. Thanks to Bruno Prémont for the patch.
3032 Also, the poisoning of various string functions has been restricted
3034 * collectd: Fix a memory leak in the global value cache. With every
3035 *missing* value a couple of bytes would be leaked. Another memory
3036 leak in the configuration handling code has been fixed. Thanks to
3037 Niraj Tolia for reporting these issues.
3038 * collectd: Fix an off-by-one error in the ignorelist functionality.
3039 When using regular expressions, the last character would be missing,
3040 possibly matching differently from what one would expect.
3041 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3043 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3044 Linzberger for reporting the bug.
3045 * iptables plugin: Fix an off-by-one error. If a string was just one
3046 character too long, it was truncated instead of reporting an error.
3047 * network plugin: Fix a memory leak in the configuration handling
3048 code. Thanks to Niraj Tolia for reporting this issue.
3049 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
3050 * postgresql plugin: Don't reopen connection during reinitialization.
3051 This fixes a bug under Solaris and potentially other platforms.
3052 Missing calls to `PQclear' have been added, too. This fixes memory
3053 leaks. Thanks to ``Admin'' for reporting these bugs.
3054 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3056 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3057 problems with some `libc's. Thanks to Matthias Lay for reporting the
3060 2008-09-04, Version 4.5.0
3061 * collectd: Added the ability to flush certain identifiers.

3067 Notifications upon added and removed sensors can now be generated.
3068 * notify_desktop plugin: This new plugin sends notifications to the
3069 X desktop using the structure defined in the `Desktop Notification
3071 * notify_email plugin: This new plugin sends out notifications via
3072 email, using the `esmtp' library.
3073 * onewire plugin: The new experimental(!) onewire plugin reads values,
3074 such as temperatures, from sensors connected to the computer via the
3076 * perl plugin: Improved synchronized access to internal data structures
3077 and fixed a possible dead-lock.
3078 * perl plugin: Added the ability to flush certain identifiers and marked
3079 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3081 * perl plugin: Added the ability to configure Perl plugins.

3089 using Linux ACPI thermal zone data.
3091 2009-01-02, Version 4.4.5
3092 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3093 file may be in both locations, especially when the database was
3094 installed in a non-standard path. Thanks to Dusty Doris for
3096 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3097 Solaris, in the configure script automatically.

3138 * memcached plugin: Fix a too short timeout and a related file
3140 * memory plugin: A typo in the libstatgrab code has been fixed.
3141 * snmp plugin: Fix a possible memory leak.
3143 2008-07-15, Version 4.4.2
3144 * build system: Use pkg-config to detect the upsclient library.
3145 * collectd: Try even harder to determine the endianness of the
3146 architecture collectd is being built on.

3149 * dns plugin: Fix compilation errors with BIND versions 19991001
3151 * network plugin: Bugfix in the init routine: The init function
3152 cleared a buffer regardless of its contents. This could lead to lost
3153 values under Solaris.
3154 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
3155 * vserver plugin: Remove usage of the thread-unsafe `readdir'
3157 * wireless plugin: Work around incorrect noise and power values
3158 returned by some broken drivers.
3160 2008-06-03, Version 4.4.1
3161 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
3162 to kyrone for reporting this.
3163 * collectd: Fixed min/max output in notifications generated by
3165 * collectd-nagios: Fix the protocol used to communicate with the
3167 * perl plugin: Fail noisily, but don't shutdown the daemon, if
3168 initialization has errors. An issue with Perl 5.10 has been fixed.
3169 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
3170 René Rebe and Siegmund Gorr for reporting this.
3172 2008-05-06, Version 4.4.0
3173 * collectd: Internal code cleanups.
3174 * collectd: Added support for a `Flush' command in the unixsock and
3175 exec plugins. This command can be used to force a plugin (or all) to
3176 flush its values to disk.
3177 * collectd: Thresholds can now be configured to apply to one data
3178 source only, making it possible to configure different thresholds
3179 for each data source.
3180 * apache, nginx plugins: Added the possibility to disable host and/or
3182 * ascent plugin: The new ascent plugin reads and parses the statistics
3183 page of an Ascent server.
3184 * cpu plugin: Support for the statgrab library has been added.
3185 * disk plugin: The possibility to ignore certain disks or collect only
3186 specific disks has been added.

3189 sensor values via IPMI, the intelligent platform management
3191 * iptables plugin: The iptc library that is used by the iptables
3192 plugin has been added to the distribution, because it is not
3193 provided by all distributions and removed from at least one.
3194 * powerdns plugin: The new powerdns plugin reads statistics from an
3195 authoritative or a recursing PowerDNS name server.
3196 * rrdtool plugin: The size of the files generated with the default
3197 configuration has been decreased.
3198 * tail plugin: The new tail plugin can be used to gather statistics by
3199 continuously reading from log files.
3200 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
3201 TeamSpeak2 server and collects statistics about the number of users
3202 and number of channels.
3203 * users plugin: Support for the statgrab library has been added.
3204 * vmem plugin: The new vmem plugin collects very detailed statistics
3205 about the virtual memory subsystem of Linux.
3207 2008-08-30, Version 4.3.4
3208 * Build system: Improved detection of and linking with the statgrab
3210 * collectd: Portability fixes, especially to determine endianness more
3212 * Various plugins: Fix format strings.
3213 * disk plugin: A fix for giving disks under Linux 2.4 the right names
3214 again has been applied.
3215 * memcached plugin: Fix a too short timeout and a related file
3217 * memory plugin: A typo in the libstatgrab code has been fixed.
3218 * network plugin: A fix in the initialization function solves problems

3226 * build system: Improved detection of several libraries, especially if
3227 they are in non-standard paths.
3228 * build system: Portability fixes: Automatically define "_REENTRANT"
3229 if the libc expects it.
3230 * collectd: Error and warning messages have been improved.
3231 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3233 * apache plugin: Allocate new memory when reading a webpage instead of
3234 using a buffer of static size.
3235 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3237 * hddtemp plugin: Error and warning messages have been improved.
3238 * sensors plugin: Fix sensor collection for some chip types.
3240 2008-03-29, Version 4.3.2
3241 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3242 `Persist' threshold options.
3243 * collectd: Fix handling of missing values in the global value cache.
3244 * collectd: Improved error messages when parsing the configuration.
3245 * sensors plugin: Fix temperature collection with libsensors4.
3246 * unixsock plugin: Fix mixed input and output operation on streams.
3247 * wireless plugin: Fix reading noise value.
3249 2008-03-05, Version 4.3.1
3250 * exec plugin: Set supplementary group IDs.
3252 + Use `memcpy' when constructing/parsing a package to avoid
3253 alignment problems on weird architectures, such as Sparc.
3254 + Translate doubles to/from the x86 byte representation to ensure
3255 cross-platform compatibility.
3256 * ping plugin: Correct the handling of the `TTL' setting.
3257 * swap plugin: Reapply a patch for Solaris.
3258 * tcpconns plugin: Portability improvements.
3260 2008-02-18, Version 4.3.0
3261 * collectd: Notifications have been added to the daemon. Notifications
3262 are status messages that may be associated with a data instance.
3263 * collectd: Threshold checking has been added to the daemon. This
3264 means that you can configure threshold values for each data
3265 instance. If this threshold is exceeded a notification will be
3267 * collectd: The new `FQDNLookup' option tells the daemon to use the
3268 full qualified domain name as the hostname, not just the host part
3269 es returned by `gethostname(2)'.
3270 * collectd: Support for more than one `TypesDB' file has been added.
3271 This is useful when one such file is included in a package but one
3272 wants to add custom type definitions.
3273 * collectd: The `Include' config option has been expanded to handle
3274 entire directories and shell wildcards.
3275 * collectdmon: The new `collectdmon' binary detects when collectd
3276 terminates and automatically restarts it again.
3277 * csv plugin: The CSV plugin is now able to store counter values as a
3278 rate, using the `StoreRates' configuration option.
3279 * exec plugin: Handling of notifications has been added and the
3280 ability to pass arguments to the executed programs has been added.
3281 * hddtemp plugin: The new `TranslateDevicename' option lets you
3282 disable the translation from device names to major-minor-numbers.
3283 * logfile plugin: Handling of notifications has been added.
3284 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3285 domain name lookups in this plugin.
3286 * perl plugin: Many internal changes added support for handling multiple
3287 threads making the plugin reasonably usable inside collectd. The API has
3288 been extended to support notifications and export global variables to
3289 Perl plugins; callbacks now have to be identified by name rather than a
3290 pointer to a subroutine. The plugin is no longer experimental.
3291 * uuid plugin: The new UUID plugin sets the hostname to an unique
3292 identifier for this host. This is meant for setups where each client
3293 may migrate to another physical host, possibly going through one or
3294 more name changes in the process. Thanks to Richard Jones from
3295 Red Hat's Emerging Technology group for this plugin.
3296 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3297 CPU, disk and network statistics about guest systems on the same
3298 physical server. Thanks to Richard Jones from Red Hat's Emerging
3299 Technology group for this plugin.
3301 2008-04-22, Version 4.2.7
3302 * build system: Improved detection of several libraries, especially if
3303 they are in non-standard paths.
3304 * build system: Portability fixes: Automatically define "_REENTRANT"
3305 if the libc expects it.
3306 * collectd: Error and warning messages have been improved.
3307 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3309 * apache plugin: Allocate new memory when reading a webpage instead of
3310 using a buffer of static size.
3311 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3313 * hddtemp plugin: Error and warning messages have been improved.
3314 * sensors plugin: Fix sensor collection for some chip types.
3316 2008-03-29, Version 4.2.6
3317 * collectd: Improved error messages when parsing the configuration.
3318 * sensors plugin: Fix temperature collection with libsensors4.
3319 * unixsock plugin: Fix mixed input and output operation on streams.
3320 * wireless plugin: Fix reading noise value.
3322 2008-03-04, Version 4.2.5
3323 * apache plugin: Improved initialization and error messages.
3324 * exec plugin: Set supplementary group IDs.
3326 + Create separate threads for reading from the socket and parsing
3327 and dispatching incoming packets. Versions prior to this may have
3328 problems in high-load situations, where the socket receive buffers
3329 overflows, resulting in gaps in the data.
3330 + Use `memcpy' when constructing/parsing a package to avoid
3331 alignment problems on weird architectures, such as Sparc.
3332 + Translate doubles to/from the x86 byte representation to ensure
3333 cross-platform compatibility.
3334 * ping plugin: Correct the handling of the `TTL' setting.
3335 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3336 * swap plugin: Reapply a patch for Solaris.
3337 * tcpconns plugin: Portability improvements.
3339 2008-01-21, Version 4.2.4
3340 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3341 the permission on the socket as documented in the manpage. Thanks to
3342 Evgeny Chukreev for fixing this issue.
3343 * collectd: The documentation has been improved.
3345 2007-12-28, Version 4.2.3
3346 * sensors plugin: Updated the plugin to build and work with version 3
3347 of the libsensors library.
3349 2007-12-15, Version 4.2.2
3350 * nginx plugin: Incorrect comparison of strings lead to a segfault
3351 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3353 * logfile plugin: The config option `Timestamp' was handled
3354 incorrectly and basically always active. Thanks to Luke Heberling
3357 2007-11-08, Version 4.2.1
3358 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3359 enabled on the host.
3360 * snmp plugin: Fix a memory leak.
3362 2007-10-27, Version 4.2.0
3363 * collectd: The new config option `Include' lets you include other
3364 configfiles and thus split up your config into smaller parts. This
3365 may be especially interesting for the snmp plugin to keep the data
3366 definitions separate from the host definitions.
3367 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3368 (number of connections, octets and packets for each service and
3369 destination). Thanks to Sebastian Harl for this plugin.
3370 * memcached plugin: The new `memcached' plugin connects to a memcached
3371 daemon process and collects statistics of this distributed caching
3372 system. Thanks to Antony Dovgal for contributing this plugin.
3373 * nginx plugin: The new `nginx' plugin reads the status page of an
3374 nginx daemon and saves the handled connections and requests.
3375 * perl plugin: Many changes, including the added `EnableDebugger'
3376 config option which lets you debug your Perl plugins more easily.
3377 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3378 be more thread-safe otherwise by locking calls to the library.
3379 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3380 correct the values returned by SNMP-agents. If a <data> block is
3381 defined as `table' the instance is now optional. The sequence number
3382 is used as the type-instance in this case. The new `InstancePrefix'
3383 option allows to add arbitrary prefixes to the type-instance.
3384 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3385 certain TCP connections and what state they're in. This can be used
3386 to see how many connections your FTP server has to handle or how
3387 many outgoing connections your mailserver has open.
3389 2008-01-11, Version 4.1.6
3390 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3391 the permission on the socket as documented in the manpage. Thanks to
3392 Evgeny Chukreev for fixing this issue.
3393 * collectd: The documentation has been improved.
3395 2007-12-27, Version 4.1.5
3396 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3398 * sensors plugin: Updated the plugin to build and work with version 3
3399 of the libsensors library.
3401 2007-11-08, Version 4.1.4
3402 * Build system: Improve detection of the rrd library, especially if
3403 it's in a non-standard location.
3404 * Build system: A bug when parsing the argument for
3405 `--with-libnetsnmp' has been fixed.
3406 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3407 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3408 a deadlock or delay when shutting down the daemon.
3409 * snmp plugin: Fix a memory leak.
3411 2007-10-24, Version 4.1.3
3412 * collectd: A build issue under Solaris has been resolved by renaming
3414 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3415 be more thread-safe otherwise by locking calls to the library.
3417 2007-09-28, Version 4.1.2
3418 * apcups plugin: Fix reporting of the `load percent' data.
3419 * wireless plugin: Correct the handling of cards returning signal and
3420 noise quality as percentage.
3421 * perl plugin: Fix a possible buffer overflow in get_module_name().
3422 * build system: Further improve the detection of libraries.
3423 * netlink plugin: Build issues under some older versions of the Linux
3424 includes (i. e. Debian Sarge) have been fixed.
3425 * snmp plugin: Fix a potential segfault when a host times out. Add
3426 support for the `timeticks' type.
3428 2007-09-12, Version 4.1.1
3429 * Build system: The detection of `libnetlink' has been improved.
3430 * collectd: The documentation has been fixed in numerous places.
3431 * exec plugin: Setting the group under which to run a program has been
3433 * collectd: The `sstrerror' function was improved to work correctly
3434 with the broken GNU version of `strerror_r'.
3435 * collectd: Write an error message to STDERR when loading of a plugin
3437 * apcups plugin: Fix the `types' used to submit the values: They still
3438 has an `apcups_' prefix which doesn't work anymore.
3439 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3440 whatever the client thinks is `now'..
3442 2007-09-01, Version 4.1.0
3443 * Build system: The build system has been changed to automatically
3444 disable all plugins, which are missing dependencies. The dependency
3445 checking has been removed from the plugins themselves to remove
3447 * Flexible interval: The interval of collected data is now sent along
3448 with the data itself over the network, so that the interval-settings
3449 of server and clients no longer needs to match.
3450 * netlink plugin: The new `netlink' plugin connects to the Linux
3451 kernel using a netlink socket and uses it to query information about
3452 interfaces, qdiscs and classes.
3453 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3454 to not block data collection.
3455 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3456 network devices, such as switches, routers, thermometers, rack
3457 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3459 * unixsock plugin: Added the `LISTVAL' command.
3460 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3461 of music played with xmms.
3463 2007-09-28, Version 4.0.9
3464 * apcups plugin: Fix reporting of the `load percent' data.
3465 * wireless plugin: Correct the handling of cards returning signal and
3466 noise quality as percentage.
3467 * perl plugin: Fix a possible buffer overflow in get_module_name().
3469 2007-09-12, Version 4.0.8
3470 * collectd: The `sstrerror' function was improved to work correctly
3471 with the broken GNU version of `strerror_r'.
3472 * collectd: Write an error message to STDERR when loading of a plugin
3474 * apcups plugin: Fix the `types' used to submit the values: They still
3475 has an `apcups_' prefix which doesn't work anymore.
3476 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3477 whatever the client thinks is `now'..
3479 2007-08-26, Version 4.0.7
3480 * documentation: Some typos have been fixed and some information has
3482 * build system: Many fixes for detecting libraries in unusual places,
3483 such as on RedHat systems. The affected libraries are `libcurl',
3484 `libmysql', and `libupsclient'.
3485 * network plugin: Allow the `Port' option to be specified as a number
3486 (i. e. without quotes).
3487 * nut plugin: A fix allows linking the nut plugin against
3488 libupsclient, version >= 2.2.0.
3489 * processes plugin: Fix a potential segmentation fault.
3491 2007-07-30, Version 4.0.6
3492 * sensors plugin: Fix the ignorelist functionality: Only the `type
3493 instance' was used to match against the list, but the documentation
3494 told otherwise. This release fixes the code, so it complies with the
3496 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3497 configuration messages will end up in the logging facility.
3498 * conrtib/fedora: The contributed specfile for Fedora has been
3501 2007-07-05, Version 4.0.5
3502 * Portability: More fixes for OpenBSD have been included.
3504 2007-06-24, Version 4.0.4
3505 * cpu plugin: Fixed the Solaris code.

3507 * interface plugin: Fixed the Solaris code.
3508 * load plugin: Fixed the alternative `/proc' Linux code.
3509 * memory plugin: Fixed the Solaris code.
3510 * oconfig: Don't require `-lfl' anymore.
3512 2007-06-19, Version 4.0.3
3513 * cpu plugin: Fix the Darwin / Mac OS X code.
3514 * ping plugin: Use the return value of `getpid', not its address.
3515 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3516 initialized correctly.
3517 * configure: Added `--with-nan-emulation' to aid cross compilation.
3519 2007-06-12, Version 4.0.2

3521 they're given in numerically form.
3523 2007-06-07, Version 4.0.1
3524 * iptables plugin: A bug in the configuration routine has been fixed.
3525 Setting a comment in the configfile will no longer cause a
3528 2007-06-03, Version 4.0.0
3529 * collectd: The plugin-infrastructure has been changed to allow for
3530 more types of plugins, namely `write' and `log' plugins.
3531 * collectd: The read-function has been changed to read many plugins in
3532 parallel, using threads. Thus, plugins generally need to use
3533 thread-safe functions from now on.
3534 * collectd: The '-t' command line options allows to perform syntax tests
3535 of the configuration file and exit immediately.
3536 * csv plugin: The new `csv' plugin handles output to `comma separated
3538 * rrdtool plugin: The new `rrdtool' plugin handles output to
3539 RRD-files. Data can be cached to combine multiple updates into one
3540 write to increase IO-performance.
3541 * network plugin: The new `network' plugin handles IO via the network.
3542 It implements a different, much more extensible protocol which can
3543 combine many values in one packet, decreasing the number of UDP-
3544 packets being sent. It can read from and send to the network and
3545 with the appropriate configuration even forward packets to other
3547 * unixsock plugin: The new `unixsock' plugin provides an interface to
3548 communicate with the daemon while it is running. Right now the
3549 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3551 * perl plugin: The new `perl' plugin allows you to write extensions
3552 for collectd in the scripting-language Perl.
3553 * logfile plugin: The new `logfile' plugin writes logmessages to files
3554 or STDOUT or STDERR.
3555 * syslog plugin: The new `syslog' plugin sends logmessages to the
3556 system's syslog daemon.
3557 * entropy plugin: The new `entropy' plugin collects the amount of
3558 entropy currently being available to the system.
3559 * exec plugin: The new `exec' plugin forks child processes and reads
3560 back values provided by the forked processes.
3561 * iptables plugin: The new `iptables' plugin reads counters from
3562 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3564 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3565 to Peter Holik for contributing this plugin.
3566 * nut plugin: The new `nut' plugin connects the upsd of the `network
3567 ups tools' and reads information about the connected UPS.
3568 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3569 connections) field was added by Florent Monbillard.
3570 * collectd-nagios: The new `collectd-nagios' binary queries values
3571 from collectd, parses them and exits according to Nagios-standards.
3572 * manpages: The manpages have been improved a lot.
3574 2007-09-28, Version 3.11.7
3575 * wireless plugin: Correct the handling of cards returning signal and
3576 noise quality as percentage.
3578 2007-08-31, Version 3.11.6
3579 * processes plugin: Fix a potential segmentation fault.
3581 2007-05-29, Version 3.11.5
3582 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3583 * ntpd plugin: Fix a potential buffer overflow.
3584 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3585 were accounted as `zombies'.
3587 2007-04-10, Version 3.11.4
3588 * dns plugin: Change the order of includes to make the plugin compile
3591 2007-03-30, Version 3.11.3
3592 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3593 of the unused `COLLECT_KSTAT'.
3595 2007-02-11, Version 3.11.2
3596 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3597 NULL-pointer may have been passed to `printf' which causes a
3598 segfault with some libcs.
3600 2007-02-10, Version 3.11.1
3601 * df plugin: Some wrong defines have been fixed so the plugin works
3602 under Solaris again.
3603 * dns plugin: The usage of a struct has been fixed to work with
3605 * processes plugin: Some missing defines have been added so the plugin
3606 compiles cleanly under FreeBSD and presumably other UNIXes.
3608 2006-12-22, Version 3.11.0
3609 * collectd: The new command line option `-P' makes it easier for
3610 distributors to change the location of PID-files.
3611 * collectd: The daemon shuts down faster now which makes it easier to
3612 write init.d-scripts for it.
3613 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3614 caused problems every now and then.
3615 * df plugin: New config options allow to ignore certain mountpoints,
3616 filesystem types or devices.
3617 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3618 and interprets it. It collects traffic as well as qtype, opcode and
3620 * email plugin: Sebastian Harl has contributed this plugin which
3621 counts received mails in categories (e. g. ham, spam, virus), spam
3622 score (as given by SpamAssassin) and check types.
3623 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3624 uses `mbmon' to gather information from sensors on the motherboard.
3625 * processes plugin: Collect detailed statistics for configured
3626 processes, that's process and thread count, CPU usage, resident
3627 segment size and pagefaults.
3628 * multimeter plugin: Peter Holik contributed a new plugin which
3629 queries multimeters.
3630 * sensors plugin: Lubos Stanek has put much effort into improving this
3631 plugin, including `extended naming', collection of voltage values
3632 and the possibility to ignore certain values.
3634 2006-12-21, Version 3.10.4
3635 * Max Kellermann has identified a bug in the server routine: When
3636 opening a socket fails the daemon will (re)try opening the socket in
3637 an endless loop, ultimately leading to a `EMFILE' error.
3639 2006-11-04, Version 3.10.3
3640 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3641 ntpd's reply was sent in more than one packet, the buffer size was
3642 calculated incorrectly, resulting in the reading of uninitialized or
3645 2006-11-01, Version 3.10.2
3646 * The sample config file has been improved.
3647 * Errors in the manpages have been corrected.
3648 * The ping-plugin now adds hosts during initialization, not during
3649 startup. This speeds up startup when no network connectivity is
3650 available. Also, the hosts are being added later when the network is
3652 * Improved BSD-support for the df-plugin.
3653 * Fixed syntax errors in the swap-plugin for Mac OS X.
3654 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3656 * Don't disable the mysql-plugin if connecting to the database fails
3657 during initialization. Instead, try again in increasing intervals.
3659 2006-07-19, Version 3.10.1
3660 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3661 the apcups cannot be reached, unconnected sockets will pile up and
3662 eventually lead to `Too many open files' errors.
3664 2006-07-09, Version 3.10.0
3665 * The `disk' plugin has been ported to Darwin.
3666 * The `battery' plugin should work on many Apple computers now.
3667 * The `traffic' plugin can now ignore certain interfaces. Also,
3668 statistics for sent/received packets and errors have been added.

3670 to Anthony Gialluca for contributing this plugin and providing me
3671 with a test environment :)
3672 * A plugin for monitoring an NTP instance and the local clock drift
3675 2006-06-25, Version 3.9.4
3676 * The Solaris code in the `swap' plugin has been changed to reflect
3677 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3679 * The debugging system has been fixed to work with the Sun libc.
3680 * When built without librrd the variable `operating_mode' could be
3681 uninitialized. Thanks to David Elliot for reporting the bug.
3683 2006-06-01, Version 3.9.3
3684 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3685 operating systems also profit from the changes, but I wasn't able to
3687 * Changed the build system to find the netinet-includes under FreeBSD
3688 and therefore successfully build the `liboping' library there.
3690 2006-05-09, Version 3.9.2
3691 * Applied a patch to the `liboping' library. Due to a bug in the
3692 sequence checking the `ping' plugin stopped working after
3693 approximately 7.6 days.
3695 2006-05-09, Version 3.8.5
3696 * Applied a patch to the `liboping' library. Due to a bug in the
3697 sequence checking the `ping' plugin stopped working after
3698 approximately 7.6 days.
3700 2006-04-21, Version 3.9.1
3701 * Build issues with Solaris and possible other architectures have been
3703 * Problems when building the `apache'-plugin without `libcurl' have
3705 * A bug in the `ping' plugin has been fixed. Sorry folks.
3707 2006-04-02, Version 3.9.0
3708 * A plugin to monitor the Apache webserver has been added.
3709 <http://httpd.apache.org/>
3710 * A plugin to collect statistics about virtual servers using VServer.
3711 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3713 * A plugin for wireless LAN cards has been added. It monitors signal
3714 strength, link quality and noise ratio..
3715 * A plugin for Apple hardware sensors has been added.
3716 * An option to compile collectd with different `step' and `heartbeat'
3717 settings has been added. The size of RRAs is no longer static but
3718 calculated based on the settings for `step' and `width'.
3719 * The `ping' plugin can now be configured to use a certain TTL.
3720 * A plugin to monitor the hardware sensors of Apple computers has been
3722 * The plugins `cpu', `memory', `processes' and `traffic' have been
3723 ported to Mach/Darwin (Mac OS X).
3724 * The `log mode' has been contributed by Christophe Kalt. It writes
3725 the data into text files rather than RRD files.
3727 2006-04-09, Version 3.8.4
3728 * Applied patch by Vincent Stehlé which improves the disk-name
3729 resolution in the `hddtemp' plugin for Linux systems.
3731 2006-04-02, Version 3.8.3
3732 * Applied a patch by James Byers: The MySQL plugin was not working
3733 with MySQL 5.0.2 or later.
3735 2006-03-14, Version 3.8.2
3736 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3737 the GNU libc, because it points to `/etc/fstab' rather than
3740 2006-03-13, Version 3.8.1
3741 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3742 * Fixes in the debian `postinst' and `init.d' scripts.
3744 2006-03-09, Version 3.8.0
3745 * The `ping' plugin no longer uses `libping' but a self written
3746 library named `liboping'. With this library it's possible to ping
3747 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3749 2006-02-18, Version 3.7.2
3750 * A simple bug in the `battery' plugin has been fixed. It should now
3751 work with ACPI based batteries as well. Thanks to Sebastian for
3753 * Fixing a bug that prevented collectd to be built without librrd.
3754 Thanks to Werner Heuser for reporting it.
3756 2006-02-04, Version 3.7.1
3757 * The new network code has been improved to build with older versions
3759 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3760 to Tommie Gannert for this patch.
3762 2006-01-30, Version 3.7.0
3763 * The `battery' plugin has been added. It collects information about
3765 * The MySQL plugin has been improved: It now writes two more RRD
3766 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3767 * The `cpufreq' plugin now reads another file since the file it did
3768 read so far causes much overhead in the kernel. Also, you need root
3769 to read the old file, but not to read the new one.
3770 * The `hddtemp' plugin can now be configured to connect to another
3771 address and/or port than localhost.
3772 * The `df' plugin now prefers `statvfs' over `statfs'.
3773 * The network code has been rewritten. collectd now supports unicast
3774 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3775 be set in the configfile.
3777 2006-01-24, Version 3.6.2
3778 * Due to a bug in the configfile handling collectd wouldn't start in
3779 client mode. This released fixes this.
3781 2006-01-20, Version 3.6.1
3782 * Due to a bug in `configure.in' all modules and the binary were
3783 linked against `libmysqlclient'. This issue is solved by this
3786 2006-01-17, Version 3.6.0
3787 * A config file has been added. This allows for loading only specific
3789 * A `df' plugin has been added.
3790 * A `mysql' plugin has been added.
3791 * The `ping' plugin doesn't entirely give up hope when a socket error
3792 occurred, but will back of and increase the intervals between tries.
3794 2006-01-21, Version 3.5.2
3795 * Fixed yet another bug in the signal handling.. Stupid typo..
3796 * Improved the ping plugin to not give up on socket errors (backport
3799 2005-12-18, Version 3.5.1
3800 * The PID-file is now deleted correctly when shutting down the daemon.
3801 * SIGINT and SIGTERM are now handled correctly.
3803 2005-12-16, Version 3.5.0 (Revision 326)
3804 * A bug in the `load' module under Solaris has been fixed.
3805 * The `users' module has been contributed by Sebastian Harl. It counts
3806 currently logged in users.
3807 * The CPU module now works under FreeBSD without the use of
3808 `libstatgrab', however SMP support is missing.
3809 * The default directories for the RRD files and the PID file now
3810 depend on the compile time setting of `localstatedir'.
3812 2005-11-15, Version 3.4.0 (Revision 236)
3813 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3814 from gentoo's bugzilla for writing the patch.
3815 * The build dependency for librrd has been removed. Binaries built
3816 without librrd are client-only and will multicast their value as
3817 with the `-c' argument.
3818 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3819 * The newly introduced `-f' switch prevents daemon initialization
3820 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3821 Barcellos for this patch.
3823 2005-11-04, Version 3.3.0 (Revision 216)
3824 * New modules have been added:
3825 - `serial', for monitoring traffic on the serial interfaces
3826 - `nfs', for graphing NFS procedure calls
3827 - `tape', traffic from/to tape devices
3828 * The memory.rrd now accepts more than 4Gig of memory.
3830 2005-10-26, Version 3.2.0 (Revision 200)
3831 * Support for graphing the processes has been added (thanks to Lyonel

3834 between polls up to one day.
3835 * The init.d files have been improved.
3836 * Problems with the spec file have been fixed.
3838 2005-10-16, Version 3.1.0 (Revision 194)
3839 * Added the `setsid' syscall to the startup code.
3840 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3842 2005-09-30, Version 3.0.0 (Revision 184)
3843 * The ability to send/receive data to/from the network (think
3844 multicast) has been added.
3845 * Modules have been split up into shared libraries can be loaded at
3846 runtime. The biggest advantage is that the core program doesn't need
3847 to be linked against an external library.
3848 * A patch by George Kargiotakis has been applied: It fixes the sensors
3849 behaviour then more than one sensor is being queried.
3851 2005-09-16, Version 2.1.0 (Revision 172)
3852 * A module for swap statistics has been added.
3854 2005-09-09, Version 2.0.0 (Revision 135)
3855 * Filenames can no longer be configured at program startup. The only
3856 options as of this version are the directory and ping hosts.
3857 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3858 Soft-IRQ statistics are added to `System'.
3859 * Diskstats now collect read and write bytes, not sectors.
3860 * Ping statistics can now be collected for more than one host. There
3861 is no default any more: If no host is given no host will be pinged.
3862 * A self-written patch for libping has been applied so it builds
3865 2005-09-01, Version 1.8.1 (Revision 123)
3866 * Much improved configure-script: libraries and features may now be
3868 * More detailed warnings/error messages when RRD update fails.
3870 2005-08-29, Version 1.8.0:
3871 * Support for collecting disk statistics under Solaris.
3873 2005-08-25, Version 1.7.0:
3874 * Support for libstatgrab[1] for load, memory usage and network
3875 traffic. CPU- and disk-usage are not (yet) supported, since
3876 libstatgrab returns insufficient information. I will contact the
3878 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3879 aren't necessarily counted linear which is now handled correctly.
3880 [1]: http://www.i-scream.org/libstatgrab/
3882 2005-08-21, Version 1.6.0:
3883 * Basic support for Solaris: System load and cpu-usage can be
3884 collected under Solaris, too. Other stats will follow later.
3885 * Many fixes in the autoconf-script
3886 * Collection/Museum scripts have been added under contrib/museum
3887 * collectd may now be started in unprivileged mode, though ping
3888 statistics will not work.
3890 2005-07-17, Version 1.5.1:
3891 * Diskstats-RRDs now use major/minor for naming. Some systems have
3892 weird strings as disk-names..
3894 2005-07-17, Version 1.5:
3895 * A new module, diskstats, has been added. It collects information
3896 about the disks and partitions.
3898 2005-07-11, Version 1.4.2:
3899 * The meminfo module has been changed to work with more platforms
3900 and/or kernel versions.
3902 2005-07-10, Version 1.4.1: Correct traffic stats
3903 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3904 forgot to correct when I changed that module.
3906 2005-07-09, Version 1.4: More traffic stats
3907 * Traffic is now collected for all interfaces that can be found
3908 * Temperature-statistics are read from lm-sensors if available
3910 2005-07-08, Version 1.3: CPU stats
3911 * Collecting CPU statistics now
3913 2005-07-12, Version 1.2: Using syslog
3914 * collectd is now using the syslog facility to report errors, warnings
3916 * The default directory is now /var/db/collectd
3918 2005-07-10, Version 1.1: Minor changes
3919 * Nothing really useful to say ;)
3921 2005-07-09, Version 1.0: Initial Version
3922 * The following modules are provided:
