2676 2009-12-18, Version 4.7.5
2677 * Build system, java plugin: Don't use “find -L” to search for Java
2678 headers, because it's a GNU extension.
2679 * Build system: Support for parallel builds has been improved. Thanks
2680 Sebastian Harl and Stefan Völkel for looking into this.
2681 * collectd: Print error messages to STDERR if no log plugin has been
2683 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
2684 * network plugin: The license has been changed to LGPL 2.1.
2685 * oracle plugin: Reconnect to the database if the connection dies.
2686 * rrdcached plugin: Work-around for a bug in RRDtool 1.4rc2 has been

2689 containing control characters are now interpreted as hex-strings.
2690 * unixsock plugin: A memory leak in the LISTVAL command has been
2691 fixed. Thanks to Ben Knight for his patch.
2693 2009-10-03, Version 4.7.4
2694 * Build system: Issues when building the iptables plugin have been
2696 * exec plugin: Clear the signal block mask before calling exec(2).
2697 * perl plugin: Declare the “environ” variable. This solves build
2698 issues on some platforms.
2699 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
2700 Andrés J. Díaz for the patch.
2701 * unixsock plugin: Fix a (well hidden) race condition related to file
2702 descriptor handling.
2704 2009-09-13, Version 4.7.3
2705 * collectd: Fix a possible but very rare invalid “free” in the caching
2706 code. Thanks to Sebastian Harl for the patch.
2707 * collectd: Remove old values when a cache entry is marked as missing.
2708 This way the “GETVAL” command of the UnixSock plugin doesn't return
2709 old, no longer valid values when this happens. Thanks to Andrés J.
2711 * collectd: The “plugin_unregister_read” function has been fixed.
2712 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2713 to follow redirects. Thanks to Joey Hess for reporting this bug.

2720 is linked with the shipped library, too.
2721 * java plugin: Delay creating the JVM until after the daemon has
2722 forked. The JVM internally creates threads that are lost when
2723 forking. This means that Java-based plugins are now configured
2724 during the init-phase, i. e. later than other plugins.
2725 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
2726 to Alan Pevec for the patch.
2727 * network plugin: Fix the handling of the “CacheFlush” option: The

2749 details have been added to the configuration summary. Support for
2750 libtool 2.2 has been added.
2751 * collectd: Two bugs with the threshold checking have been fixed. The
2752 first one prevented thresholds to be checked at all, the second one
2753 caused wrong behavior with the persistency option. Thanks to Andrés
2754 J. Díaz for fixing these problems.
2755 * collectd: Handling of the `Include' configuration option has been
2757 * rrdtool plugin: Make sure initialization is run only once. This
2758 resolves problems under Solaris and potentially other systems.
2759 Thanks to Amit Gupta for reporting this bug.
2760 * java plugin: Make it possible to use dots ('.') instead of slashes
2761 ('/') as the class separator. Thanks to Randy Rizun for pointing

2777 multicast traffic from Ganglia's gmond daemon.
2778 * java plugin: The new java plugin exports the collectd API to Java,
2779 making it possible to write extensions to collectd in Java.
2780 * memcachec plugin: The new memcachec plugin queries data from a
2781 memcached daemon and parses it similar to the cURL plugin. Thanks to
2782 Doug MacEachern for the initial code.
2783 * memcached plugin: Support for connections over UNIX domain sockets
2784 has been added. Thanks to Franck Lombardi for the patch.

2798 * table plugin: The new Table plugin provides parsing for table-like
2799 structured files, such as many files beneath /proc.
2800 * ted plugin: The new TED plugin reads power consumption measurements
2801 from “The Energy Detective” (TED). Thanks to Eric Reed for this
2803 * onewire plugin: The new `Interval' option allows collecting
2804 information from OneWire sensors at arbitrary intervals.
2805 * ping plugin: Support for collecting the drop rate and standard
2806 deviation of round-trip times has been added.
2807 * uptime plugin: The new uptime plugin can collect the server's
2808 uptime. Thanks to Marco Chiappero for the patch.
2810 2009-09-10, Version 4.6.5
2811 * collectd: Remove old values when a cache entry is marked as missing.
2812 This way the “GETVAL” command of the UnixSock plugin doesn't return

2840 * Build system, various plugins: Many build fixes for FreeBSD,
2841 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
2842 for many fixes and providing a build system for many platforms,
2843 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2844 providing an OpenBSD system.
2845 * collectd: Two bugs with the threshold checking have been fixed. The
2846 first one prevented thresholds to be checked at all, the second one
2847 caused wrong behavior with the persistency option. Thanks to Andrés
2848 J. Díaz for fixing these problems.
2849 * collectd: Handling of the `Include' configuration option has been

2865 * filter subsystem: Allow `Chains' without default targets.
2866 * liboping: A patch to comply with strict aliasing rules has been
2868 * timediff match: Fix a typo: The match was registered with a wrong
2869 name which prevented this match to be used as documented. Thanks to
2870 Bruno Prémont for finding this problem.
2871 * bind plugin: Fix collection of the cached RR sets. The number of RR
2872 sets currently in the cache was collected as a counter value, which
2873 is nonsense. Thanks to Bruno Prémont for implementing this.
2874 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2875 primarily BSDs, don't take it well and crash.
2876 * oracle plugin: Portability to 64 bit systems has been improved.
2877 * postgresql plugin: The default configuration has been improved.
2878 * rrdtool plugin: Fix a possible race condition: If the network plugin

2889 faults. Thanks to Peter Holik for his patch.
2891 2009-02-16, Version 4.6.0
2892 * collectd: Added the `filter chain' infrastructure, which allows the
2893 user to use `matches' and `targets' to control value processing.
2894 * collectd: The new `-T' command line argument allows more in-depth
2895 testing of a configuration. Thanks to Doug MacEachern for the patch.
2896 * collectd-nagios: The Nagios integration command has been updated to
2897 use libcollectdclient. The `percentage' aggregation function has
2898 been added. Thanks to Fabian Linzberger for the patch.

2910 statistics, allowing very detailed name server statistics. Thanks to
2911 Bruno Prémont for this plugin.
2912 * cpu plugin: Report `interrupt' separately when using
2913 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
2914 example for native OpenBSD support, has been added. Thanks to Simon
2915 Kuhnle for the patch.
2916 * csv plugin: Make it possible to write values to STDOUT instead of
2917 files. This is meant for testing purposes mostly. The output written
2918 to STDOUT is compatible with the exec plugin. Thanks to Doug
2919 MacEachern for the patch.
2920 * curl plugin: This new plugin can be used to read web pages and parse
2921 them using the same mechanism that's used in the tail plugin.
2922 * dbi plugin: This new plugin allows you to connect to a variety of
2923 relational databases and use SQL to gather custom statistics from
2924 it. It is similar to the already existing PostgreSQL plugin but uses
2925 libdbi to communicate with the database(s).
2926 * interface plugin: Use the ignorelist framework when selecting /
2927 ignoring interfaces. This allows one to use regular expressions to
2928 select interfaces, too.
2929 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
2930 Thanks to Bruno Prémont for this patch.
2931 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

2944 * perl plugin: Export the newly added plugin_write() to Perl plugins.
2945 * perl plugin: Added support for `notification meta data'.
2946 * perl plugin: Added support for the `filter chain' infrastructure by
2947 allowing plugins to register `matches' and `targets'.
2948 * postgresql plugin: The preferred configuration syntax has been
2949 updated to be in line with the syntax used by the new dbi and oracle
2950 plugins. The compatibility code for the old syntax is present.
2951 Support for the new `Result' blocks and the interval parameter has
2953 * processes plugin: Stacksize and virtual memory usage statistics have
2954 been added. Portability fixes.
2955 * rrdcached plugin: This new plugin uses the (still in development)
2956 RRD accelerator daemon, rrdcached. This daemon works very similar to
2957 the original rrdtool plugin of collectd, but adds some more nice

2975 Tomasz Pala for the patch.
2976 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2978 * rrdtool plugin: Fix a possible race condition: If the network plugin
2979 is initialized and dispatches a value before the rrdtool plugin is
2980 initialized, the daemon may crash.
2981 * memory plugin: Fix a potential problem under Solaris.
2983 2009-02-22, Version 4.5.3

2993 code. Thanks to "thated" for reporting this.
2995 2009-01-02, Version 4.5.2
2996 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2997 file may be in both locations, especially when the database was
2998 installed in a non-standard path. Thanks to Dusty Doris for
3000 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3001 Solaris, in the configure script automatically.
3002 * build system, tcpconns plugin: Check for `kvm_nlist' and
3003 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3004 library with similar functions to the BSD variant, but doesn't
3005 provide these necessary functions.
3006 * collectd.conf(5): Various fixes and clarifications.
3007 * collectd: Remove a GNUism (unnamed unions), thus improving
3009 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.

3012 * filecount plugin: Fix an off-by-one error. This error may cause a
3014 * network plugin: Fix the handling of `type' in the network protocol.
3015 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3016 much larger buffer. This caused the `type' to be transferred much
3017 more often than necessary. In some cases, e. g. the `cpu' and
3018 `cpufreq' plugins being used at the same time, data may be corrupted
3019 in those files. Thanks to Bruno Prémont for debugging and reporting
3021 * processes plugin: Fix a possible segmentation fault when specifying
3022 invalid configuration options.
3023 * unixsock plugin: Make sure the initialization function is run only
3024 once. This resolves a file descriptor leak under systems which run
3025 the initialization more than once, such as Solaris.
3027 2008-10-16, Version 4.5.1
3028 * build system: Change `--enable-<plugin>' to abort with an error if
3029 dependencies are not met. Thanks to Bruno Prémont for the patch.
3030 Also, the poisoning of various string functions has been restricted
3032 * collectd: Fix a memory leak in the global value cache. With every
3033 *missing* value a couple of bytes would be leaked. Another memory
3034 leak in the configuration handling code has been fixed. Thanks to
3035 Niraj Tolia for reporting these issues.
3036 * collectd: Fix an off-by-one error in the ignorelist functionality.
3037 When using regular expressions, the last character would be missing,
3038 possibly matching differently from what one would expect.
3039 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3041 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3042 Linzberger for reporting the bug.
3043 * iptables plugin: Fix an off-by-one error. If a string was just one
3044 character too long, it was truncated instead of reporting an error.
3045 * network plugin: Fix a memory leak in the configuration handling
3046 code. Thanks to Niraj Tolia for reporting this issue.
3047 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
3048 * postgresql plugin: Don't reopen connection during reinitialization.
3049 This fixes a bug under Solaris and potentially other platforms.
3050 Missing calls to `PQclear' have been added, too. This fixes memory
3051 leaks. Thanks to ``Admin'' for reporting these bugs.
3052 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3054 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3055 problems with some `libc's. Thanks to Matthias Lay for reporting the
3058 2008-09-04, Version 4.5.0
3059 * collectd: Added the ability to flush certain identifiers.

3065 Notifications upon added and removed sensors can now be generated.
3066 * notify_desktop plugin: This new plugin sends notifications to the
3067 X desktop using the structure defined in the `Desktop Notification
3069 * notify_email plugin: This new plugin sends out notifications via
3070 email, using the `esmtp' library.
3071 * onewire plugin: The new experimental(!) onewire plugin reads values,
3072 such as temperatures, from sensors connected to the computer via the
3074 * perl plugin: Improved synchronized access to internal data structures
3075 and fixed a possible dead-lock.
3076 * perl plugin: Added the ability to flush certain identifiers and marked
3077 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3079 * perl plugin: Added the ability to configure Perl plugins.

3087 using Linux ACPI thermal zone data.
3089 2009-01-02, Version 4.4.5
3090 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3091 file may be in both locations, especially when the database was
3092 installed in a non-standard path. Thanks to Dusty Doris for
3094 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3095 Solaris, in the configure script automatically.

3147 * dns plugin: Fix compilation errors with BIND versions 19991001
3149 * network plugin: Bugfix in the init routine: The init function
3150 cleared a buffer regardless of its contents. This could lead to lost
3151 values under Solaris.
3152 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
3153 * vserver plugin: Remove usage of the thread-unsafe `readdir'
3155 * wireless plugin: Work around incorrect noise and power values
3156 returned by some broken drivers.
3158 2008-06-03, Version 4.4.1
3159 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
3160 to kyrone for reporting this.
3161 * collectd: Fixed min/max output in notifications generated by
3163 * collectd-nagios: Fix the protocol used to communicate with the
3165 * perl plugin: Fail noisily, but don't shutdown the daemon, if
3166 initialization has errors. An issue with Perl 5.10 has been fixed.
3167 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
3168 René Rebe and Siegmund Gorr for reporting this.
3170 2008-05-06, Version 4.4.0
3171 * collectd: Internal code cleanups.
3172 * collectd: Added support for a `Flush' command in the unixsock and
3173 exec plugins. This command can be used to force a plugin (or all) to
3174 flush its values to disk.
3175 * collectd: Thresholds can now be configured to apply to one data
3176 source only, making it possible to configure different thresholds
3177 for each data source.
3178 * apache, nginx plugins: Added the possibility to disable host and/or
3180 * ascent plugin: The new ascent plugin reads and parses the statistics
3181 page of an Ascent server.

3187 sensor values via IPMI, the intelligent platform management
3189 * iptables plugin: The iptc library that is used by the iptables
3190 plugin has been added to the distribution, because it is not
3191 provided by all distributions and removed from at least one.
3192 * powerdns plugin: The new powerdns plugin reads statistics from an
3193 authoritative or a recursing PowerDNS name server.
3194 * rrdtool plugin: The size of the files generated with the default
3195 configuration has been decreased.
3196 * tail plugin: The new tail plugin can be used to gather statistics by
3197 continuously reading from log files.
3198 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
3199 TeamSpeak2 server and collects statistics about the number of users
3200 and number of channels.
3201 * users plugin: Support for the statgrab library has been added.
3202 * vmem plugin: The new vmem plugin collects very detailed statistics
3203 about the virtual memory subsystem of Linux.
3205 2008-08-30, Version 4.3.4
3206 * Build system: Improved detection of and linking with the statgrab
3208 * collectd: Portability fixes, especially to determine endianness more
3210 * Various plugins: Fix format strings.
3211 * disk plugin: A fix for giving disks under Linux 2.4 the right names
3212 again has been applied.
3213 * memcached plugin: Fix a too short timeout and a related file
3215 * memory plugin: A typo in the libstatgrab code has been fixed.
3216 * network plugin: A fix in the initialization function solves problems
3218 * nginx plugin: A thread-unsafe function has been replaced.

3220 * wireless plugin: A work-around for broken wireless drivers has been
3223 2008-04-22, Version 4.3.3
3224 * build system: Improved detection of several libraries, especially if
3225 they are in non-standard paths.
3226 * build system: Portability fixes: Automatically define "_REENTRANT"
3227 if the libc expects it.
3228 * collectd: Error and warning messages have been improved.
3229 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3231 * apache plugin: Allocate new memory when reading a webpage instead of
3232 using a buffer of static size.
3233 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3235 * hddtemp plugin: Error and warning messages have been improved.
3236 * sensors plugin: Fix sensor collection for some chip types.
3238 2008-03-29, Version 4.3.2
3239 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3240 `Persist' threshold options.
3241 * collectd: Fix handling of missing values in the global value cache.
3242 * collectd: Improved error messages when parsing the configuration.
3243 * sensors plugin: Fix temperature collection with libsensors4.
3244 * unixsock plugin: Fix mixed input and output operation on streams.
3245 * wireless plugin: Fix reading noise value.
3247 2008-03-05, Version 4.3.1
3248 * exec plugin: Set supplementary group IDs.
3250 + Use `memcpy' when constructing/parsing a package to avoid
3251 alignment problems on weird architectures, such as Sparc.
3252 + Translate doubles to/from the x86 byte representation to ensure
3253 cross-platform compatibility.
3254 * ping plugin: Correct the handling of the `TTL' setting.
3255 * swap plugin: Reapply a patch for Solaris.
3256 * tcpconns plugin: Portability improvements.
3258 2008-02-18, Version 4.3.0
3259 * collectd: Notifications have been added to the daemon. Notifications
3260 are status messages that may be associated with a data instance.
3261 * collectd: Threshold checking has been added to the daemon. This
3262 means that you can configure threshold values for each data
3263 instance. If this threshold is exceeded a notification will be
3265 * collectd: The new `FQDNLookup' option tells the daemon to use the
3266 full qualified domain name as the hostname, not just the host part
3267 es returned by `gethostname(2)'.
3268 * collectd: Support for more than one `TypesDB' file has been added.
3269 This is useful when one such file is included in a package but one
3270 wants to add custom type definitions.
3271 * collectd: The `Include' config option has been expanded to handle
3272 entire directories and shell wildcards.
3273 * collectdmon: The new `collectdmon' binary detects when collectd
3274 terminates and automatically restarts it again.
3275 * csv plugin: The CSV plugin is now able to store counter values as a
3276 rate, using the `StoreRates' configuration option.
3277 * exec plugin: Handling of notifications has been added and the
3278 ability to pass arguments to the executed programs has been added.
3279 * hddtemp plugin: The new `TranslateDevicename' option lets you
3280 disable the translation from device names to major-minor-numbers.
3281 * logfile plugin: Handling of notifications has been added.
3282 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3283 domain name lookups in this plugin.
3284 * perl plugin: Many internal changes added support for handling multiple
3285 threads making the plugin reasonably usable inside collectd. The API has
3286 been extended to support notifications and export global variables to
3287 Perl plugins; callbacks now have to be identified by name rather than a
3288 pointer to a subroutine. The plugin is no longer experimental.
3289 * uuid plugin: The new UUID plugin sets the hostname to an unique
3290 identifier for this host. This is meant for setups where each client
3291 may migrate to another physical host, possibly going through one or
3292 more name changes in the process. Thanks to Richard Jones from
3293 Red Hat's Emerging Technology group for this plugin.
3294 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3295 CPU, disk and network statistics about guest systems on the same
3296 physical server. Thanks to Richard Jones from Red Hat's Emerging
3297 Technology group for this plugin.
3299 2008-04-22, Version 4.2.7
3300 * build system: Improved detection of several libraries, especially if
3301 they are in non-standard paths.
3302 * build system: Portability fixes: Automatically define "_REENTRANT"
3303 if the libc expects it.
3304 * collectd: Error and warning messages have been improved.
3305 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3307 * apache plugin: Allocate new memory when reading a webpage instead of
3308 using a buffer of static size.
3309 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3311 * hddtemp plugin: Error and warning messages have been improved.
3312 * sensors plugin: Fix sensor collection for some chip types.
3314 2008-03-29, Version 4.2.6
3315 * collectd: Improved error messages when parsing the configuration.
3316 * sensors plugin: Fix temperature collection with libsensors4.
3317 * unixsock plugin: Fix mixed input and output operation on streams.
3318 * wireless plugin: Fix reading noise value.
3320 2008-03-04, Version 4.2.5
3321 * apache plugin: Improved initialization and error messages.
3322 * exec plugin: Set supplementary group IDs.
3324 + Create separate threads for reading from the socket and parsing
3325 and dispatching incoming packets. Versions prior to this may have
3326 problems in high-load situations, where the socket receive buffers
3327 overflows, resulting in gaps in the data.
3328 + Use `memcpy' when constructing/parsing a package to avoid
3329 alignment problems on weird architectures, such as Sparc.
3330 + Translate doubles to/from the x86 byte representation to ensure
3331 cross-platform compatibility.
3332 * ping plugin: Correct the handling of the `TTL' setting.
3333 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3334 * swap plugin: Reapply a patch for Solaris.
3335 * tcpconns plugin: Portability improvements.
3337 2008-01-21, Version 4.2.4
3338 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3339 the permission on the socket as documented in the manpage. Thanks to
3340 Evgeny Chukreev for fixing this issue.
3341 * collectd: The documentation has been improved.
3343 2007-12-28, Version 4.2.3
3344 * sensors plugin: Updated the plugin to build and work with version 3
3345 of the libsensors library.
3347 2007-12-15, Version 4.2.2
3348 * nginx plugin: Incorrect comparison of strings lead to a segfault
3349 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3351 * logfile plugin: The config option `Timestamp' was handled
3352 incorrectly and basically always active. Thanks to Luke Heberling
3355 2007-11-08, Version 4.2.1
3356 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3357 enabled on the host.
3358 * snmp plugin: Fix a memory leak.
3360 2007-10-27, Version 4.2.0
3361 * collectd: The new config option `Include' lets you include other
3362 configfiles and thus split up your config into smaller parts. This
3363 may be especially interesting for the snmp plugin to keep the data
3364 definitions separate from the host definitions.
3365 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3366 (number of connections, octets and packets for each service and
3367 destination). Thanks to Sebastian Harl for this plugin.
3368 * memcached plugin: The new `memcached' plugin connects to a memcached
3369 daemon process and collects statistics of this distributed caching
3370 system. Thanks to Antony Dovgal for contributing this plugin.
3371 * nginx plugin: The new `nginx' plugin reads the status page of an
3372 nginx daemon and saves the handled connections and requests.
3373 * perl plugin: Many changes, including the added `EnableDebugger'
3374 config option which lets you debug your Perl plugins more easily.
3375 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3376 be more thread-safe otherwise by locking calls to the library.
3377 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3378 correct the values returned by SNMP-agents. If a <data> block is
3379 defined as `table' the instance is now optional. The sequence number
3380 is used as the type-instance in this case. The new `InstancePrefix'
3381 option allows to add arbitrary prefixes to the type-instance.
3382 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3383 certain TCP connections and what state they're in. This can be used
3384 to see how many connections your FTP server has to handle or how
3385 many outgoing connections your mailserver has open.
3387 2008-01-11, Version 4.1.6
3388 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3389 the permission on the socket as documented in the manpage. Thanks to
3390 Evgeny Chukreev for fixing this issue.
3391 * collectd: The documentation has been improved.
3393 2007-12-27, Version 4.1.5
3394 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3396 * sensors plugin: Updated the plugin to build and work with version 3
3397 of the libsensors library.
3399 2007-11-08, Version 4.1.4
3400 * Build system: Improve detection of the rrd library, especially if
3401 it's in a non-standard location.
3402 * Build system: A bug when parsing the argument for
3403 `--with-libnetsnmp' has been fixed.
3404 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3405 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3406 a deadlock or delay when shutting down the daemon.
3407 * snmp plugin: Fix a memory leak.
3409 2007-10-24, Version 4.1.3
3410 * collectd: A build issue under Solaris has been resolved by renaming
3412 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3413 be more thread-safe otherwise by locking calls to the library.
3415 2007-09-28, Version 4.1.2
3416 * apcups plugin: Fix reporting of the `load percent' data.
3417 * wireless plugin: Correct the handling of cards returning signal and
3418 noise quality as percentage.
3419 * perl plugin: Fix a possible buffer overflow in get_module_name().
3420 * build system: Further improve the detection of libraries.
3421 * netlink plugin: Build issues under some older versions of the Linux
3422 includes (i. e. Debian Sarge) have been fixed.
3423 * snmp plugin: Fix a potential segfault when a host times out. Add
3424 support for the `timeticks' type.
3426 2007-09-12, Version 4.1.1
3427 * Build system: The detection of `libnetlink' has been improved.
3428 * collectd: The documentation has been fixed in numerous places.
3429 * exec plugin: Setting the group under which to run a program has been
3431 * collectd: The `sstrerror' function was improved to work correctly
3432 with the broken GNU version of `strerror_r'.
3433 * collectd: Write an error message to STDERR when loading of a plugin
3435 * apcups plugin: Fix the `types' used to submit the values: They still
3436 has an `apcups_' prefix which doesn't work anymore.
3437 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3438 whatever the client thinks is `now'..
3440 2007-09-01, Version 4.1.0
3441 * Build system: The build system has been changed to automatically
3442 disable all plugins, which are missing dependencies. The dependency
3443 checking has been removed from the plugins themselves to remove
3445 * Flexible interval: The interval of collected data is now sent along
3446 with the data itself over the network, so that the interval-settings
3447 of server and clients no longer needs to match.
3448 * netlink plugin: The new `netlink' plugin connects to the Linux
3449 kernel using a netlink socket and uses it to query information about
3450 interfaces, qdiscs and classes.
3451 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3452 to not block data collection.
3453 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3454 network devices, such as switches, routers, thermometers, rack
3455 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3457 * unixsock plugin: Added the `LISTVAL' command.
3458 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3459 of music played with xmms.
3461 2007-09-28, Version 4.0.9
3462 * apcups plugin: Fix reporting of the `load percent' data.
3463 * wireless plugin: Correct the handling of cards returning signal and
3464 noise quality as percentage.
3465 * perl plugin: Fix a possible buffer overflow in get_module_name().
3467 2007-09-12, Version 4.0.8
3468 * collectd: The `sstrerror' function was improved to work correctly
3469 with the broken GNU version of `strerror_r'.
3470 * collectd: Write an error message to STDERR when loading of a plugin
3472 * apcups plugin: Fix the `types' used to submit the values: They still
3473 has an `apcups_' prefix which doesn't work anymore.
3474 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3475 whatever the client thinks is `now'..
3477 2007-08-26, Version 4.0.7
3478 * documentation: Some typos have been fixed and some information has
3480 * build system: Many fixes for detecting libraries in unusual places,
3481 such as on RedHat systems. The affected libraries are `libcurl',
3482 `libmysql', and `libupsclient'.
3483 * network plugin: Allow the `Port' option to be specified as a number
3484 (i. e. without quotes).
3485 * nut plugin: A fix allows linking the nut plugin against
3486 libupsclient, version >= 2.2.0.
3487 * processes plugin: Fix a potential segmentation fault.
3489 2007-07-30, Version 4.0.6
3490 * sensors plugin: Fix the ignorelist functionality: Only the `type
3491 instance' was used to match against the list, but the documentation
3492 told otherwise. This release fixes the code, so it complies with the
3494 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3495 configuration messages will end up in the logging facility.
3496 * conrtib/fedora: The contributed specfile for Fedora has been
3499 2007-07-05, Version 4.0.5
3500 * Portability: More fixes for OpenBSD have been included.
3502 2007-06-24, Version 4.0.4
3503 * cpu plugin: Fixed the Solaris code.

3505 * interface plugin: Fixed the Solaris code.
3506 * load plugin: Fixed the alternative `/proc' Linux code.
3507 * memory plugin: Fixed the Solaris code.
3508 * oconfig: Don't require `-lfl' anymore.
3510 2007-06-19, Version 4.0.3
3511 * cpu plugin: Fix the Darwin / Mac OS X code.
3512 * ping plugin: Use the return value of `getpid', not its address.
3513 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3514 initialized correctly.
3515 * configure: Added `--with-nan-emulation' to aid cross compilation.
3517 2007-06-12, Version 4.0.2
3518 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3519 they're given in numerically form.
3521 2007-06-07, Version 4.0.1
3522 * iptables plugin: A bug in the configuration routine has been fixed.
3523 Setting a comment in the configfile will no longer cause a
3526 2007-06-03, Version 4.0.0
3527 * collectd: The plugin-infrastructure has been changed to allow for
3528 more types of plugins, namely `write' and `log' plugins.
3529 * collectd: The read-function has been changed to read many plugins in
3530 parallel, using threads. Thus, plugins generally need to use
3531 thread-safe functions from now on.
3532 * collectd: The '-t' command line options allows to perform syntax tests
3533 of the configuration file and exit immediately.
3534 * csv plugin: The new `csv' plugin handles output to `comma separated
3536 * rrdtool plugin: The new `rrdtool' plugin handles output to
3537 RRD-files. Data can be cached to combine multiple updates into one
3538 write to increase IO-performance.
3539 * network plugin: The new `network' plugin handles IO via the network.
3540 It implements a different, much more extensible protocol which can
3541 combine many values in one packet, decreasing the number of UDP-
3542 packets being sent. It can read from and send to the network and
3543 with the appropriate configuration even forward packets to other
3545 * unixsock plugin: The new `unixsock' plugin provides an interface to
3546 communicate with the daemon while it is running. Right now the
3547 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3549 * perl plugin: The new `perl' plugin allows you to write extensions
3550 for collectd in the scripting-language Perl.
3551 * logfile plugin: The new `logfile' plugin writes logmessages to files
3552 or STDOUT or STDERR.
3553 * syslog plugin: The new `syslog' plugin sends logmessages to the
3554 system's syslog daemon.
3555 * entropy plugin: The new `entropy' plugin collects the amount of
3556 entropy currently being available to the system.
3557 * exec plugin: The new `exec' plugin forks child processes and reads
3558 back values provided by the forked processes.
3559 * iptables plugin: The new `iptables' plugin reads counters from
3560 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3562 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3563 to Peter Holik for contributing this plugin.
3564 * nut plugin: The new `nut' plugin connects the upsd of the `network
3565 ups tools' and reads information about the connected UPS.
3566 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3567 connections) field was added by Florent Monbillard.
3568 * collectd-nagios: The new `collectd-nagios' binary queries values
3569 from collectd, parses them and exits according to Nagios-standards.
3570 * manpages: The manpages have been improved a lot.
3572 2007-09-28, Version 3.11.7
3573 * wireless plugin: Correct the handling of cards returning signal and
3574 noise quality as percentage.
3576 2007-08-31, Version 3.11.6
3577 * processes plugin: Fix a potential segmentation fault.
3579 2007-05-29, Version 3.11.5
3580 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3581 * ntpd plugin: Fix a potential buffer overflow.
3582 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3583 were accounted as `zombies'.
3585 2007-04-10, Version 3.11.4
3586 * dns plugin: Change the order of includes to make the plugin compile
3589 2007-03-30, Version 3.11.3
3590 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3591 of the unused `COLLECT_KSTAT'.
3593 2007-02-11, Version 3.11.2
3594 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3595 NULL-pointer may have been passed to `printf' which causes a
3596 segfault with some libcs.
3598 2007-02-10, Version 3.11.1
3599 * df plugin: Some wrong defines have been fixed so the plugin works
3600 under Solaris again.
3601 * dns plugin: The usage of a struct has been fixed to work with
3603 * processes plugin: Some missing defines have been added so the plugin
3604 compiles cleanly under FreeBSD and presumably other UNIXes.
3606 2006-12-22, Version 3.11.0
3607 * collectd: The new command line option `-P' makes it easier for
3608 distributors to change the location of PID-files.
3609 * collectd: The daemon shuts down faster now which makes it easier to
3610 write init.d-scripts for it.
3611 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3612 caused problems every now and then.
3613 * df plugin: New config options allow to ignore certain mountpoints,
3614 filesystem types or devices.
3615 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3616 and interprets it. It collects traffic as well as qtype, opcode and
3618 * email plugin: Sebastian Harl has contributed this plugin which
3619 counts received mails in categories (e. g. ham, spam, virus), spam
3620 score (as given by SpamAssassin) and check types.
3621 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3622 uses `mbmon' to gather information from sensors on the motherboard.
3623 * processes plugin: Collect detailed statistics for configured
3624 processes, that's process and thread count, CPU usage, resident
3625 segment size and pagefaults.
3626 * multimeter plugin: Peter Holik contributed a new plugin which
3627 queries multimeters.
3628 * sensors plugin: Lubos Stanek has put much effort into improving this
3629 plugin, including `extended naming', collection of voltage values
3630 and the possibility to ignore certain values.
3632 2006-12-21, Version 3.10.4
3633 * Max Kellermann has identified a bug in the server routine: When
3634 opening a socket fails the daemon will (re)try opening the socket in
3635 an endless loop, ultimately leading to a `EMFILE' error.
3637 2006-11-04, Version 3.10.3
3638 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3639 ntpd's reply was sent in more than one packet, the buffer size was
3640 calculated incorrectly, resulting in the reading of uninitialized or
3643 2006-11-01, Version 3.10.2
3644 * The sample config file has been improved.
3645 * Errors in the manpages have been corrected.
3646 * The ping-plugin now adds hosts during initialization, not during
3647 startup. This speeds up startup when no network connectivity is
3648 available. Also, the hosts are being added later when the network is
3650 * Improved BSD-support for the df-plugin.
3651 * Fixed syntax errors in the swap-plugin for Mac OS X.
3652 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3654 * Don't disable the mysql-plugin if connecting to the database fails
3655 during initialization. Instead, try again in increasing intervals.
3657 2006-07-19, Version 3.10.1
3658 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3659 the apcups cannot be reached, unconnected sockets will pile up and
3660 eventually lead to `Too many open files' errors.
3662 2006-07-09, Version 3.10.0
3663 * The `disk' plugin has been ported to Darwin.
3664 * The `battery' plugin should work on many Apple computers now.
3665 * The `traffic' plugin can now ignore certain interfaces. Also,
3666 statistics for sent/received packets and errors have been added.

3668 to Anthony Gialluca for contributing this plugin and providing me
3669 with a test environment :)
3670 * A plugin for monitoring an NTP instance and the local clock drift
3673 2006-06-25, Version 3.9.4
3674 * The Solaris code in the `swap' plugin has been changed to reflect
3675 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3677 * The debugging system has been fixed to work with the Sun libc.
3678 * When built without librrd the variable `operating_mode' could be
3679 uninitialized. Thanks to David Elliot for reporting the bug.
3681 2006-06-01, Version 3.9.3
3682 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3683 operating systems also profit from the changes, but I wasn't able to
3685 * Changed the build system to find the netinet-includes under FreeBSD
3686 and therefore successfully build the `liboping' library there.
3688 2006-05-09, Version 3.9.2
3689 * Applied a patch to the `liboping' library. Due to a bug in the
3690 sequence checking the `ping' plugin stopped working after
3691 approximately 7.6 days.
3693 2006-05-09, Version 3.8.5
3694 * Applied a patch to the `liboping' library. Due to a bug in the
3695 sequence checking the `ping' plugin stopped working after
3696 approximately 7.6 days.
3698 2006-04-21, Version 3.9.1
3699 * Build issues with Solaris and possible other architectures have been
3701 * Problems when building the `apache'-plugin without `libcurl' have
3703 * A bug in the `ping' plugin has been fixed. Sorry folks.
3705 2006-04-02, Version 3.9.0
3706 * A plugin to monitor the Apache webserver has been added.
3707 <http://httpd.apache.org/>
3708 * A plugin to collect statistics about virtual servers using VServer.
3709 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3711 * A plugin for wireless LAN cards has been added. It monitors signal
3712 strength, link quality and noise ratio..
3713 * A plugin for Apple hardware sensors has been added.
3714 * An option to compile collectd with different `step' and `heartbeat'
3715 settings has been added. The size of RRAs is no longer static but
3716 calculated based on the settings for `step' and `width'.
3717 * The `ping' plugin can now be configured to use a certain TTL.
3718 * A plugin to monitor the hardware sensors of Apple computers has been
3720 * The plugins `cpu', `memory', `processes' and `traffic' have been
3721 ported to Mach/Darwin (Mac OS X).
3722 * The `log mode' has been contributed by Christophe Kalt. It writes
3723 the data into text files rather than RRD files.
3725 2006-04-09, Version 3.8.4
3726 * Applied patch by Vincent Stehlé which improves the disk-name
3727 resolution in the `hddtemp' plugin for Linux systems.
3729 2006-04-02, Version 3.8.3
3730 * Applied a patch by James Byers: The MySQL plugin was not working
3731 with MySQL 5.0.2 or later.
3733 2006-03-14, Version 3.8.2
3734 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3735 the GNU libc, because it points to `/etc/fstab' rather than
3738 2006-03-13, Version 3.8.1
3739 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3740 * Fixes in the debian `postinst' and `init.d' scripts.
3742 2006-03-09, Version 3.8.0
3743 * The `ping' plugin no longer uses `libping' but a self written
3744 library named `liboping'. With this library it's possible to ping
3745 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3747 2006-02-18, Version 3.7.2
3748 * A simple bug in the `battery' plugin has been fixed. It should now
3749 work with ACPI based batteries as well. Thanks to Sebastian for
3751 * Fixing a bug that prevented collectd to be built without librrd.
3752 Thanks to Werner Heuser for reporting it.
3754 2006-02-04, Version 3.7.1
3755 * The new network code has been improved to build with older versions
3757 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3758 to Tommie Gannert for this patch.
3760 2006-01-30, Version 3.7.0
3761 * The `battery' plugin has been added. It collects information about
3763 * The MySQL plugin has been improved: It now writes two more RRD
3764 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3765 * The `cpufreq' plugin now reads another file since the file it did
3766 read so far causes much overhead in the kernel. Also, you need root
3767 to read the old file, but not to read the new one.
3768 * The `hddtemp' plugin can now be configured to connect to another
3769 address and/or port than localhost.
3770 * The `df' plugin now prefers `statvfs' over `statfs'.
3771 * The network code has been rewritten. collectd now supports unicast
3772 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3773 be set in the configfile.
3775 2006-01-24, Version 3.6.2
3776 * Due to a bug in the configfile handling collectd wouldn't start in
3777 client mode. This released fixes this.
3779 2006-01-20, Version 3.6.1
3780 * Due to a bug in `configure.in' all modules and the binary were
3781 linked against `libmysqlclient'. This issue is solved by this
3784 2006-01-17, Version 3.6.0
3785 * A config file has been added. This allows for loading only specific
3787 * A `df' plugin has been added.
3788 * A `mysql' plugin has been added.
3789 * The `ping' plugin doesn't entirely give up hope when a socket error
3790 occurred, but will back of and increase the intervals between tries.
3792 2006-01-21, Version 3.5.2
3793 * Fixed yet another bug in the signal handling.. Stupid typo..
3794 * Improved the ping plugin to not give up on socket errors (backport
3797 2005-12-18, Version 3.5.1
3798 * The PID-file is now deleted correctly when shutting down the daemon.
3799 * SIGINT and SIGTERM are now handled correctly.
3801 2005-12-16, Version 3.5.0 (Revision 326)
3802 * A bug in the `load' module under Solaris has been fixed.
3803 * The `users' module has been contributed by Sebastian Harl. It counts
3804 currently logged in users.
3805 * The CPU module now works under FreeBSD without the use of
3806 `libstatgrab', however SMP support is missing.
3807 * The default directories for the RRD files and the PID file now
3808 depend on the compile time setting of `localstatedir'.
3810 2005-11-15, Version 3.4.0 (Revision 236)
3811 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3812 from gentoo's bugzilla for writing the patch.
3813 * The build dependency for librrd has been removed. Binaries built
3814 without librrd are client-only and will multicast their value as
3815 with the `-c' argument.
3816 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3817 * The newly introduced `-f' switch prevents daemon initialization
3818 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3819 Barcellos for this patch.
3821 2005-11-04, Version 3.3.0 (Revision 216)
3822 * New modules have been added:
3823 - `serial', for monitoring traffic on the serial interfaces
3824 - `nfs', for graphing NFS procedure calls
3825 - `tape', traffic from/to tape devices
3826 * The memory.rrd now accepts more than 4Gig of memory.
3828 2005-10-26, Version 3.2.0 (Revision 200)
3829 * Support for graphing the processes has been added (thanks to Lyonel
3831 * If reading from hddtemp fails collectd will increase the time
3832 between polls up to one day.
3833 * The init.d files have been improved.
3834 * Problems with the spec file have been fixed.
3836 2005-10-16, Version 3.1.0 (Revision 194)
3837 * Added the `setsid' syscall to the startup code.
3838 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3840 2005-09-30, Version 3.0.0 (Revision 184)
3841 * The ability to send/receive data to/from the network (think
3842 multicast) has been added.
3843 * Modules have been split up into shared libraries can be loaded at
3844 runtime. The biggest advantage is that the core program doesn't need
3845 to be linked against an external library.
3846 * A patch by George Kargiotakis has been applied: It fixes the sensors
3847 behaviour then more than one sensor is being queried.
3849 2005-09-16, Version 2.1.0 (Revision 172)
3850 * A module for swap statistics has been added.
3852 2005-09-09, Version 2.0.0 (Revision 135)
3853 * Filenames can no longer be configured at program startup. The only
3854 options as of this version are the directory and ping hosts.
3855 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3856 Soft-IRQ statistics are added to `System'.
3857 * Diskstats now collect read and write bytes, not sectors.
3858 * Ping statistics can now be collected for more than one host. There
3859 is no default any more: If no host is given no host will be pinged.
3860 * A self-written patch for libping has been applied so it builds
3863 2005-09-01, Version 1.8.1 (Revision 123)
3864 * Much improved configure-script: libraries and features may now be
3866 * More detailed warnings/error messages when RRD update fails.
3868 2005-08-29, Version 1.8.0:
3869 * Support for collecting disk statistics under Solaris.
3871 2005-08-25, Version 1.7.0:
3872 * Support for libstatgrab[1] for load, memory usage and network
3873 traffic. CPU- and disk-usage are not (yet) supported, since
3874 libstatgrab returns insufficient information. I will contact the
3876 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3877 aren't necessarily counted linear which is now handled correctly.
3878 [1]: http://www.i-scream.org/libstatgrab/
3880 2005-08-21, Version 1.6.0:
3881 * Basic support for Solaris: System load and cpu-usage can be
3882 collected under Solaris, too. Other stats will follow later.
3883 * Many fixes in the autoconf-script
3884 * Collection/Museum scripts have been added under contrib/museum
3885 * collectd may now be started in unprivileged mode, though ping
3886 statistics will not work.
3888 2005-07-17, Version 1.5.1:
3889 * Diskstats-RRDs now use major/minor for naming. Some systems have
3890 weird strings as disk-names..
3892 2005-07-17, Version 1.5:
3893 * A new module, diskstats, has been added. It collects information
3894 about the disks and partitions.
3896 2005-07-11, Version 1.4.2:
3897 * The meminfo module has been changed to work with more platforms
3898 and/or kernel versions.
3900 2005-07-10, Version 1.4.1: Correct traffic stats
3901 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3902 forgot to correct when I changed that module.
3904 2005-07-09, Version 1.4: More traffic stats
3905 * Traffic is now collected for all interfaces that can be found
3906 * Temperature-statistics are read from lm-sensors if available
3908 2005-07-08, Version 1.3: CPU stats
3909 * Collecting CPU statistics now
3911 2005-07-12, Version 1.2: Using syslog
3912 * collectd is now using the syslog facility to report errors, warnings
3914 * The default directory is now /var/db/collectd
3916 2005-07-10, Version 1.1: Minor changes
3917 * Nothing really useful to say ;)
3919 2005-07-09, Version 1.0: Initial Version
3920 * The following modules are provided:
