2735 2009-09-10, Version 4.6.5
2736 * collectd: Remove old values when a cache entry is marked as missing.
2737 This way the “GETVAL” command of the UnixSock plugin doesn't return
2738 old, no longer valid values when this happens. Thanks to Andrés J.
2740 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
2741 to follow redirects. Thanks to Joey Hess for reporting this bug.

2768 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
2769 providing an OpenBSD system.
2770 * collectd: Two bugs with the threshold checking have been fixed. The
2771 first one prevented thresholds to be checked at all, the second one
2772 caused wrong behavior with the persistency option. Thanks to Andrés
2773 J. Díaz for fixing these problems.

2791 * liboping: A patch to comply with strict aliasing rules has been
2793 * timediff match: Fix a typo: The match was registered with a wrong
2794 name which prevented this match to be used as documented. Thanks to
2795 Bruno Prémont for finding this problem.
2796 * bind plugin: Fix collection of the cached RR sets. The number of RR
2797 sets currently in the cache was collected as a counter value, which
2798 is nonsense. Thanks to Bruno Prémont for implementing this.
2799 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
2800 primarily BSDs, don't take it well and crash.
2801 * oracle plugin: Portability to 64 bit systems has been improved.
2802 * postgresql plugin: The default configuration has been improved.
2803 * rrdtool plugin: Fix a possible race condition: If the network plugin

2814 faults. Thanks to Peter Holik for his patch.
2816 2009-02-16, Version 4.6.0
2817 * collectd: Added the `filter chain' infrastructure, which allows the
2818 user to use `matches' and `targets' to control value processing.
2819 * collectd: The new `-T' command line argument allows more in-depth
2820 testing of a configuration. Thanks to Doug MacEachern for the patch.

2839 example for native OpenBSD support, has been added. Thanks to Simon
2840 Kuhnle for the patch.
2841 * csv plugin: Make it possible to write values to STDOUT instead of
2842 files. This is meant for testing purposes mostly. The output written
2843 to STDOUT is compatible with the exec plugin. Thanks to Doug
2844 MacEachern for the patch.
2845 * curl plugin: This new plugin can be used to read web pages and parse
2846 them using the same mechanism that's used in the tail plugin.
2847 * dbi plugin: This new plugin allows you to connect to a variety of
2848 relational databases and use SQL to gather custom statistics from
2849 it. It is similar to the already existing PostgreSQL plugin but uses
2850 libdbi to communicate with the database(s).
2851 * interface plugin: Use the ignorelist framework when selecting /
2852 ignoring interfaces. This allows one to use regular expressions to
2853 select interfaces, too.

2878 * processes plugin: Stacksize and virtual memory usage statistics have
2879 been added. Portability fixes.
2880 * rrdcached plugin: This new plugin uses the (still in development)
2881 RRD accelerator daemon, rrdcached. This daemon works very similar to
2882 the original rrdtool plugin of collectd, but adds some more nice

2901 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
2903 * rrdtool plugin: Fix a possible race condition: If the network plugin
2904 is initialized and dispatches a value before the rrdtool plugin is
2905 initialized, the daemon may crash.
2906 * memory plugin: Fix a potential problem under Solaris.
2908 2009-02-22, Version 4.5.3

2918 code. Thanks to "thated" for reporting this.
2920 2009-01-02, Version 4.5.2
2921 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
2922 file may be in both locations, especially when the database was
2923 installed in a non-standard path. Thanks to Dusty Doris for
2925 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
2926 Solaris, in the configure script automatically.
2927 * build system, tcpconns plugin: Check for `kvm_nlist' and
2928 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
2929 library with similar functions to the BSD variant, but doesn't
2930 provide these necessary functions.
2931 * collectd.conf(5): Various fixes and clarifications.
2932 * collectd: Remove a GNUism (unnamed unions), thus improving

2937 * filecount plugin: Fix an off-by-one error. This error may cause a
2939 * network plugin: Fix the handling of `type' in the network protocol.
2940 Due to a programming mistake, only 4 or 8 bytes would be copied to a
2941 much larger buffer. This caused the `type' to be transferred much
2942 more often than necessary. In some cases, e. g. the `cpu' and
2943 `cpufreq' plugins being used at the same time, data may be corrupted
2944 in those files. Thanks to Bruno Prémont for debugging and reporting
2946 * processes plugin: Fix a possible segmentation fault when specifying
2947 invalid configuration options.
2948 * unixsock plugin: Make sure the initialization function is run only
2949 once. This resolves a file descriptor leak under systems which run
2950 the initialization more than once, such as Solaris.
2952 2008-10-16, Version 4.5.1
2953 * build system: Change `--enable-<plugin>' to abort with an error if
2954 dependencies are not met. Thanks to Bruno Prémont for the patch.
2955 Also, the poisoning of various string functions has been restricted
2957 * collectd: Fix a memory leak in the global value cache. With every
2958 *missing* value a couple of bytes would be leaked. Another memory
2959 leak in the configuration handling code has been fixed. Thanks to
2960 Niraj Tolia for reporting these issues.
2961 * collectd: Fix an off-by-one error in the ignorelist functionality.
2962 When using regular expressions, the last character would be missing,
2963 possibly matching differently from what one would expect.
2964 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
2966 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
2967 Linzberger for reporting the bug.
2968 * iptables plugin: Fix an off-by-one error. If a string was just one
2969 character too long, it was truncated instead of reporting an error.
2970 * network plugin: Fix a memory leak in the configuration handling
2971 code. Thanks to Niraj Tolia for reporting this issue.
2972 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
2973 * postgresql plugin: Don't reopen connection during reinitialization.
2974 This fixes a bug under Solaris and potentially other platforms.

2976 leaks. Thanks to ``Admin'' for reporting these bugs.
2977 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
2979 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
2980 problems with some `libc's. Thanks to Matthias Lay for reporting the
2983 2008-09-04, Version 4.5.0
2984 * collectd: Added the ability to flush certain identifiers.

2992 X desktop using the structure defined in the `Desktop Notification
2994 * notify_email plugin: This new plugin sends out notifications via
2995 email, using the `esmtp' library.
2996 * onewire plugin: The new experimental(!) onewire plugin reads values,
2997 such as temperatures, from sensors connected to the computer via the
2999 * perl plugin: Improved synchronized access to internal data structures
3000 and fixed a possible dead-lock.
3001 * perl plugin: Added the ability to flush certain identifiers and marked
3002 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3004 * perl plugin: Added the ability to configure Perl plugins.

3015 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3016 file may be in both locations, especially when the database was
3017 installed in a non-standard path. Thanks to Dusty Doris for
3019 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3020 Solaris, in the configure script automatically.

3025 * network plugin: Fix the handling of `type' in the network protocol.
3026 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3027 much larger buffer. This caused the `type' to be transferred much
3028 more often than necessary. In some cases, e. g. the `cpu' and

3098 exec plugins. This command can be used to force a plugin (or all) to
3099 flush its values to disk.
3100 * collectd: Thresholds can now be configured to apply to one data
3101 source only, making it possible to configure different thresholds
3102 for each data source.
3103 * apache, nginx plugins: Added the possibility to disable host and/or
3105 * ascent plugin: The new ascent plugin reads and parses the statistics
3106 page of an Ascent server.

3151 * build system: Portability fixes: Automatically define "_REENTRANT"
3152 if the libc expects it.
3153 * collectd: Error and warning messages have been improved.
3154 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3156 * apache plugin: Allocate new memory when reading a webpage instead of
3157 using a buffer of static size.
3158 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3160 * hddtemp plugin: Error and warning messages have been improved.
3161 * sensors plugin: Fix sensor collection for some chip types.
3163 2008-03-29, Version 4.3.2
3164 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3165 `Persist' threshold options.
3166 * collectd: Fix handling of missing values in the global value cache.
3167 * collectd: Improved error messages when parsing the configuration.
3168 * sensors plugin: Fix temperature collection with libsensors4.
3169 * unixsock plugin: Fix mixed input and output operation on streams.
3170 * wireless plugin: Fix reading noise value.
3172 2008-03-05, Version 4.3.1
3173 * exec plugin: Set supplementary group IDs.
3175 + Use `memcpy' when constructing/parsing a package to avoid
3176 alignment problems on weird architectures, such as Sparc.
3177 + Translate doubles to/from the x86 byte representation to ensure
3178 cross-platform compatibility.
3179 * ping plugin: Correct the handling of the `TTL' setting.
3180 * swap plugin: Reapply a patch for Solaris.
3181 * tcpconns plugin: Portability improvements.
3183 2008-02-18, Version 4.3.0
3184 * collectd: Notifications have been added to the daemon. Notifications
3185 are status messages that may be associated with a data instance.
3186 * collectd: Threshold checking has been added to the daemon. This
3187 means that you can configure threshold values for each data
3188 instance. If this threshold is exceeded a notification will be
3190 * collectd: The new `FQDNLookup' option tells the daemon to use the
3191 full qualified domain name as the hostname, not just the host part
3192 es returned by `gethostname(2)'.
3193 * collectd: Support for more than one `TypesDB' file has been added.
3194 This is useful when one such file is included in a package but one
3195 wants to add custom type definitions.
3196 * collectd: The `Include' config option has been expanded to handle
3197 entire directories and shell wildcards.
3198 * collectdmon: The new `collectdmon' binary detects when collectd
3199 terminates and automatically restarts it again.
3200 * csv plugin: The CSV plugin is now able to store counter values as a
3201 rate, using the `StoreRates' configuration option.
3202 * exec plugin: Handling of notifications has been added and the
3203 ability to pass arguments to the executed programs has been added.
3204 * hddtemp plugin: The new `TranslateDevicename' option lets you
3205 disable the translation from device names to major-minor-numbers.
3206 * logfile plugin: Handling of notifications has been added.
3207 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3208 domain name lookups in this plugin.
3209 * perl plugin: Many internal changes added support for handling multiple
3210 threads making the plugin reasonably usable inside collectd. The API has
3211 been extended to support notifications and export global variables to
3212 Perl plugins; callbacks now have to be identified by name rather than a
3213 pointer to a subroutine. The plugin is no longer experimental.
3214 * uuid plugin: The new UUID plugin sets the hostname to an unique
3215 identifier for this host. This is meant for setups where each client
3216 may migrate to another physical host, possibly going through one or
3217 more name changes in the process. Thanks to Richard Jones from
3218 Red Hat's Emerging Technology group for this plugin.
3219 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3220 CPU, disk and network statistics about guest systems on the same
3221 physical server. Thanks to Richard Jones from Red Hat's Emerging
3222 Technology group for this plugin.
3224 2008-04-22, Version 4.2.7
3225 * build system: Improved detection of several libraries, especially if
3226 they are in non-standard paths.
3227 * build system: Portability fixes: Automatically define "_REENTRANT"
3228 if the libc expects it.
3229 * collectd: Error and warning messages have been improved.
3230 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3232 * apache plugin: Allocate new memory when reading a webpage instead of
3233 using a buffer of static size.
3234 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3236 * hddtemp plugin: Error and warning messages have been improved.
3237 * sensors plugin: Fix sensor collection for some chip types.
3239 2008-03-29, Version 4.2.6
3240 * collectd: Improved error messages when parsing the configuration.
3241 * sensors plugin: Fix temperature collection with libsensors4.
3242 * unixsock plugin: Fix mixed input and output operation on streams.
3243 * wireless plugin: Fix reading noise value.
3245 2008-03-04, Version 4.2.5
3246 * apache plugin: Improved initialization and error messages.
3247 * exec plugin: Set supplementary group IDs.
3249 + Create separate threads for reading from the socket and parsing
3250 and dispatching incoming packets. Versions prior to this may have
3251 problems in high-load situations, where the socket receive buffers
3252 overflows, resulting in gaps in the data.
3253 + Use `memcpy' when constructing/parsing a package to avoid
3254 alignment problems on weird architectures, such as Sparc.
3255 + Translate doubles to/from the x86 byte representation to ensure
3256 cross-platform compatibility.
3257 * ping plugin: Correct the handling of the `TTL' setting.
3258 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3259 * swap plugin: Reapply a patch for Solaris.
3260 * tcpconns plugin: Portability improvements.
3262 2008-01-21, Version 4.2.4
3263 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3264 the permission on the socket as documented in the manpage. Thanks to
3265 Evgeny Chukreev for fixing this issue.
3266 * collectd: The documentation has been improved.
3268 2007-12-28, Version 4.2.3
3269 * sensors plugin: Updated the plugin to build and work with version 3
3270 of the libsensors library.
3272 2007-12-15, Version 4.2.2
3273 * nginx plugin: Incorrect comparison of strings lead to a segfault
3274 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3276 * logfile plugin: The config option `Timestamp' was handled
3277 incorrectly and basically always active. Thanks to Luke Heberling
3280 2007-11-08, Version 4.2.1
3281 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3282 enabled on the host.
3283 * snmp plugin: Fix a memory leak.
3285 2007-10-27, Version 4.2.0
3286 * collectd: The new config option `Include' lets you include other
3287 configfiles and thus split up your config into smaller parts. This
3288 may be especially interesting for the snmp plugin to keep the data
3289 definitions separate from the host definitions.
3290 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3291 (number of connections, octets and packets for each service and
3292 destination). Thanks to Sebastian Harl for this plugin.
3293 * memcached plugin: The new `memcached' plugin connects to a memcached
3294 daemon process and collects statistics of this distributed caching
3295 system. Thanks to Antony Dovgal for contributing this plugin.
3296 * nginx plugin: The new `nginx' plugin reads the status page of an
3297 nginx daemon and saves the handled connections and requests.
3298 * perl plugin: Many changes, including the added `EnableDebugger'
3299 config option which lets you debug your Perl plugins more easily.
3300 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3301 be more thread-safe otherwise by locking calls to the library.
3302 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3303 correct the values returned by SNMP-agents. If a <data> block is
3304 defined as `table' the instance is now optional. The sequence number
3305 is used as the type-instance in this case. The new `InstancePrefix'
3306 option allows to add arbitrary prefixes to the type-instance.
3307 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3308 certain TCP connections and what state they're in. This can be used
3309 to see how many connections your FTP server has to handle or how
3310 many outgoing connections your mailserver has open.
3312 2008-01-11, Version 4.1.6
3313 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3314 the permission on the socket as documented in the manpage. Thanks to
3315 Evgeny Chukreev for fixing this issue.
3316 * collectd: The documentation has been improved.
3318 2007-12-27, Version 4.1.5
3319 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3321 * sensors plugin: Updated the plugin to build and work with version 3
3322 of the libsensors library.
3324 2007-11-08, Version 4.1.4
3325 * Build system: Improve detection of the rrd library, especially if
3326 it's in a non-standard location.
3327 * Build system: A bug when parsing the argument for
3328 `--with-libnetsnmp' has been fixed.
3329 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3330 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3331 a deadlock or delay when shutting down the daemon.
3332 * snmp plugin: Fix a memory leak.
3334 2007-10-24, Version 4.1.3
3335 * collectd: A build issue under Solaris has been resolved by renaming
3337 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3338 be more thread-safe otherwise by locking calls to the library.
3340 2007-09-28, Version 4.1.2
3341 * apcups plugin: Fix reporting of the `load percent' data.
3342 * wireless plugin: Correct the handling of cards returning signal and
3343 noise quality as percentage.
3344 * perl plugin: Fix a possible buffer overflow in get_module_name().
3345 * build system: Further improve the detection of libraries.
3346 * netlink plugin: Build issues under some older versions of the Linux
3347 includes (i. e. Debian Sarge) have been fixed.
3348 * snmp plugin: Fix a potential segfault when a host times out. Add
3349 support for the `timeticks' type.
3351 2007-09-12, Version 4.1.1
3352 * Build system: The detection of `libnetlink' has been improved.
3353 * collectd: The documentation has been fixed in numerous places.
3354 * exec plugin: Setting the group under which to run a program has been
3356 * collectd: The `sstrerror' function was improved to work correctly
3357 with the broken GNU version of `strerror_r'.
3358 * collectd: Write an error message to STDERR when loading of a plugin
3360 * apcups plugin: Fix the `types' used to submit the values: They still
3361 has an `apcups_' prefix which doesn't work anymore.
3362 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3363 whatever the client thinks is `now'..
3365 2007-09-01, Version 4.1.0
3366 * Build system: The build system has been changed to automatically
3367 disable all plugins, which are missing dependencies. The dependency
3368 checking has been removed from the plugins themselves to remove
3370 * Flexible interval: The interval of collected data is now sent along
3371 with the data itself over the network, so that the interval-settings
3372 of server and clients no longer needs to match.
3373 * netlink plugin: The new `netlink' plugin connects to the Linux
3374 kernel using a netlink socket and uses it to query information about
3375 interfaces, qdiscs and classes.
3376 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3377 to not block data collection.
3378 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3379 network devices, such as switches, routers, thermometers, rack
3380 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3382 * unixsock plugin: Added the `LISTVAL' command.
3383 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3384 of music played with xmms.
3386 2007-09-28, Version 4.0.9
3387 * apcups plugin: Fix reporting of the `load percent' data.
3388 * wireless plugin: Correct the handling of cards returning signal and
3389 noise quality as percentage.
3390 * perl plugin: Fix a possible buffer overflow in get_module_name().
3392 2007-09-12, Version 4.0.8
3393 * collectd: The `sstrerror' function was improved to work correctly
3394 with the broken GNU version of `strerror_r'.
3395 * collectd: Write an error message to STDERR when loading of a plugin
3397 * apcups plugin: Fix the `types' used to submit the values: They still
3398 has an `apcups_' prefix which doesn't work anymore.
3399 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3400 whatever the client thinks is `now'..
3402 2007-08-26, Version 4.0.7
3403 * documentation: Some typos have been fixed and some information has
3405 * build system: Many fixes for detecting libraries in unusual places,
3406 such as on RedHat systems. The affected libraries are `libcurl',
3407 `libmysql', and `libupsclient'.
3408 * network plugin: Allow the `Port' option to be specified as a number
3409 (i. e. without quotes).
3410 * nut plugin: A fix allows linking the nut plugin against
3411 libupsclient, version >= 2.2.0.
3412 * processes plugin: Fix a potential segmentation fault.
3414 2007-07-30, Version 4.0.6
3415 * sensors plugin: Fix the ignorelist functionality: Only the `type
3416 instance' was used to match against the list, but the documentation
3417 told otherwise. This release fixes the code, so it complies with the
3419 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3420 configuration messages will end up in the logging facility.
3421 * conrtib/fedora: The contributed specfile for Fedora has been
3424 2007-07-05, Version 4.0.5
3425 * Portability: More fixes for OpenBSD have been included.
3427 2007-06-24, Version 4.0.4
3428 * cpu plugin: Fixed the Solaris code.
3429 * dns plugin: Fixed a build issue for OpenBSD.
3430 * interface plugin: Fixed the Solaris code.
3431 * load plugin: Fixed the alternative `/proc' Linux code.
3432 * memory plugin: Fixed the Solaris code.
3433 * oconfig: Don't require `-lfl' anymore.
3435 2007-06-19, Version 4.0.3
3436 * cpu plugin: Fix the Darwin / Mac OS X code.
3437 * ping plugin: Use the return value of `getpid', not its address.
3438 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3439 initialized correctly.
3440 * configure: Added `--with-nan-emulation' to aid cross compilation.
3442 2007-06-12, Version 4.0.2
3443 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3444 they're given in numerically form.
3446 2007-06-07, Version 4.0.1
3447 * iptables plugin: A bug in the configuration routine has been fixed.
3448 Setting a comment in the configfile will no longer cause a
3451 2007-06-03, Version 4.0.0
3452 * collectd: The plugin-infrastructure has been changed to allow for
3453 more types of plugins, namely `write' and `log' plugins.
3454 * collectd: The read-function has been changed to read many plugins in
3455 parallel, using threads. Thus, plugins generally need to use
3456 thread-safe functions from now on.
3457 * collectd: The '-t' command line options allows to perform syntax tests
3458 of the configuration file and exit immediately.
3459 * csv plugin: The new `csv' plugin handles output to `comma separated
3461 * rrdtool plugin: The new `rrdtool' plugin handles output to
3462 RRD-files. Data can be cached to combine multiple updates into one
3463 write to increase IO-performance.
3464 * network plugin: The new `network' plugin handles IO via the network.
3465 It implements a different, much more extensible protocol which can
3466 combine many values in one packet, decreasing the number of UDP-
3467 packets being sent. It can read from and send to the network and
3468 with the appropriate configuration even forward packets to other
3470 * unixsock plugin: The new `unixsock' plugin provides an interface to
3471 communicate with the daemon while it is running. Right now the
3472 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3474 * perl plugin: The new `perl' plugin allows you to write extensions
3475 for collectd in the scripting-language Perl.
3476 * logfile plugin: The new `logfile' plugin writes logmessages to files
3477 or STDOUT or STDERR.
3478 * syslog plugin: The new `syslog' plugin sends logmessages to the
3479 system's syslog daemon.
3480 * entropy plugin: The new `entropy' plugin collects the amount of
3481 entropy currently being available to the system.
3482 * exec plugin: The new `exec' plugin forks child processes and reads
3483 back values provided by the forked processes.
3484 * iptables plugin: The new `iptables' plugin reads counters from
3485 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3487 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3488 to Peter Holik for contributing this plugin.
3489 * nut plugin: The new `nut' plugin connects the upsd of the `network
3490 ups tools' and reads information about the connected UPS.
3491 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3492 connections) field was added by Florent Monbillard.
3493 * collectd-nagios: The new `collectd-nagios' binary queries values
3494 from collectd, parses them and exits according to Nagios-standards.
3495 * manpages: The manpages have been improved a lot.
3497 2007-09-28, Version 3.11.7
3498 * wireless plugin: Correct the handling of cards returning signal and
3499 noise quality as percentage.
3501 2007-08-31, Version 3.11.6
3502 * processes plugin: Fix a potential segmentation fault.
3504 2007-05-29, Version 3.11.5
3505 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3506 * ntpd plugin: Fix a potential buffer overflow.
3507 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3508 were accounted as `zombies'.
3510 2007-04-10, Version 3.11.4
3511 * dns plugin: Change the order of includes to make the plugin compile
3514 2007-03-30, Version 3.11.3
3515 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3516 of the unused `COLLECT_KSTAT'.
3518 2007-02-11, Version 3.11.2
3519 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3520 NULL-pointer may have been passed to `printf' which causes a
3521 segfault with some libcs.
3523 2007-02-10, Version 3.11.1
3524 * df plugin: Some wrong defines have been fixed so the plugin works
3525 under Solaris again.
3526 * dns plugin: The usage of a struct has been fixed to work with
3528 * processes plugin: Some missing defines have been added so the plugin
3529 compiles cleanly under FreeBSD and presumably other UNIXes.
3531 2006-12-22, Version 3.11.0
3532 * collectd: The new command line option `-P' makes it easier for
3533 distributors to change the location of PID-files.
3534 * collectd: The daemon shuts down faster now which makes it easier to
3535 write init.d-scripts for it.
3536 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3537 caused problems every now and then.
3538 * df plugin: New config options allow to ignore certain mountpoints,
3539 filesystem types or devices.
3540 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3541 and interprets it. It collects traffic as well as qtype, opcode and
3543 * email plugin: Sebastian Harl has contributed this plugin which
3544 counts received mails in categories (e. g. ham, spam, virus), spam
3545 score (as given by SpamAssassin) and check types.
3546 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3547 uses `mbmon' to gather information from sensors on the motherboard.
3548 * processes plugin: Collect detailed statistics for configured
3549 processes, that's process and thread count, CPU usage, resident
3550 segment size and pagefaults.
3551 * multimeter plugin: Peter Holik contributed a new plugin which
3552 queries multimeters.
3553 * sensors plugin: Lubos Stanek has put much effort into improving this
3554 plugin, including `extended naming', collection of voltage values
3555 and the possibility to ignore certain values.
3557 2006-12-21, Version 3.10.4
3558 * Max Kellermann has identified a bug in the server routine: When
3559 opening a socket fails the daemon will (re)try opening the socket in
3560 an endless loop, ultimately leading to a `EMFILE' error.
3562 2006-11-04, Version 3.10.3
3563 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3564 ntpd's reply was sent in more than one packet, the buffer size was
3565 calculated incorrectly, resulting in the reading of uninitialized or
3568 2006-11-01, Version 3.10.2
3569 * The sample config file has been improved.
3570 * Errors in the manpages have been corrected.
3571 * The ping-plugin now adds hosts during initialization, not during
3572 startup. This speeds up startup when no network connectivity is
3573 available. Also, the hosts are being added later when the network is
3575 * Improved BSD-support for the df-plugin.
3576 * Fixed syntax errors in the swap-plugin for Mac OS X.
3577 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3579 * Don't disable the mysql-plugin if connecting to the database fails
3580 during initialization. Instead, try again in increasing intervals.
3582 2006-07-19, Version 3.10.1
3583 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3584 the apcups cannot be reached, unconnected sockets will pile up and
3585 eventually lead to `Too many open files' errors.
3587 2006-07-09, Version 3.10.0
3588 * The `disk' plugin has been ported to Darwin.
3589 * The `battery' plugin should work on many Apple computers now.
3590 * The `traffic' plugin can now ignore certain interfaces. Also,
3591 statistics for sent/received packets and errors have been added.
3592 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3593 to Anthony Gialluca for contributing this plugin and providing me
3594 with a test environment :)
3595 * A plugin for monitoring an NTP instance and the local clock drift
3598 2006-06-25, Version 3.9.4
3599 * The Solaris code in the `swap' plugin has been changed to reflect
3600 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3602 * The debugging system has been fixed to work with the Sun libc.
3603 * When built without librrd the variable `operating_mode' could be
3604 uninitialized. Thanks to David Elliot for reporting the bug.
3606 2006-06-01, Version 3.9.3
3607 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3608 operating systems also profit from the changes, but I wasn't able to
3610 * Changed the build system to find the netinet-includes under FreeBSD
3611 and therefore successfully build the `liboping' library there.
3613 2006-05-09, Version 3.9.2
3614 * Applied a patch to the `liboping' library. Due to a bug in the
3615 sequence checking the `ping' plugin stopped working after
3616 approximately 7.6 days.
3618 2006-05-09, Version 3.8.5
3619 * Applied a patch to the `liboping' library. Due to a bug in the
3620 sequence checking the `ping' plugin stopped working after
3621 approximately 7.6 days.
3623 2006-04-21, Version 3.9.1
3624 * Build issues with Solaris and possible other architectures have been
3626 * Problems when building the `apache'-plugin without `libcurl' have
3628 * A bug in the `ping' plugin has been fixed. Sorry folks.
3630 2006-04-02, Version 3.9.0
3631 * A plugin to monitor the Apache webserver has been added.
3632 <http://httpd.apache.org/>
3633 * A plugin to collect statistics about virtual servers using VServer.
3634 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3636 * A plugin for wireless LAN cards has been added. It monitors signal
3637 strength, link quality and noise ratio..
3638 * A plugin for Apple hardware sensors has been added.
3639 * An option to compile collectd with different `step' and `heartbeat'
3640 settings has been added. The size of RRAs is no longer static but
3641 calculated based on the settings for `step' and `width'.
3642 * The `ping' plugin can now be configured to use a certain TTL.
3643 * A plugin to monitor the hardware sensors of Apple computers has been
3645 * The plugins `cpu', `memory', `processes' and `traffic' have been
3646 ported to Mach/Darwin (Mac OS X).
3647 * The `log mode' has been contributed by Christophe Kalt. It writes
3648 the data into text files rather than RRD files.
3650 2006-04-09, Version 3.8.4
3651 * Applied patch by Vincent Stehlé which improves the disk-name
3652 resolution in the `hddtemp' plugin for Linux systems.
3654 2006-04-02, Version 3.8.3
3655 * Applied a patch by James Byers: The MySQL plugin was not working
3656 with MySQL 5.0.2 or later.
3658 2006-03-14, Version 3.8.2
3659 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3660 the GNU libc, because it points to `/etc/fstab' rather than
3663 2006-03-13, Version 3.8.1
3664 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
3665 * Fixes in the debian `postinst' and `init.d' scripts.
3667 2006-03-09, Version 3.8.0
3668 * The `ping' plugin no longer uses `libping' but a self written
3669 library named `liboping'. With this library it's possible to ping
3670 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
3672 2006-02-18, Version 3.7.2
3673 * A simple bug in the `battery' plugin has been fixed. It should now
3674 work with ACPI based batteries as well. Thanks to Sebastian for
3676 * Fixing a bug that prevented collectd to be built without librrd.
3677 Thanks to Werner Heuser for reporting it.
3679 2006-02-04, Version 3.7.1
3680 * The new network code has been improved to build with older versions
3682 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
3683 to Tommie Gannert for this patch.
3685 2006-01-30, Version 3.7.0
3686 * The `battery' plugin has been added. It collects information about
3688 * The MySQL plugin has been improved: It now writes two more RRD
3689 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
3690 * The `cpufreq' plugin now reads another file since the file it did
3691 read so far causes much overhead in the kernel. Also, you need root
3692 to read the old file, but not to read the new one.
3693 * The `hddtemp' plugin can now be configured to connect to another
3694 address and/or port than localhost.
3695 * The `df' plugin now prefers `statvfs' over `statfs'.
3696 * The network code has been rewritten. collectd now supports unicast
3697 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
3698 be set in the configfile.
3700 2006-01-24, Version 3.6.2
3701 * Due to a bug in the configfile handling collectd wouldn't start in
3702 client mode. This released fixes this.
3704 2006-01-20, Version 3.6.1
3705 * Due to a bug in `configure.in' all modules and the binary were
3706 linked against `libmysqlclient'. This issue is solved by this
3709 2006-01-17, Version 3.6.0
3710 * A config file has been added. This allows for loading only specific
3712 * A `df' plugin has been added.
3713 * A `mysql' plugin has been added.
3714 * The `ping' plugin doesn't entirely give up hope when a socket error
3715 occurred, but will back of and increase the intervals between tries.
3717 2006-01-21, Version 3.5.2
3718 * Fixed yet another bug in the signal handling.. Stupid typo..
3719 * Improved the ping plugin to not give up on socket errors (backport
3722 2005-12-18, Version 3.5.1
3723 * The PID-file is now deleted correctly when shutting down the daemon.
3724 * SIGINT and SIGTERM are now handled correctly.
3726 2005-12-16, Version 3.5.0 (Revision 326)
3727 * A bug in the `load' module under Solaris has been fixed.
3728 * The `users' module has been contributed by Sebastian Harl. It counts
3729 currently logged in users.
3730 * The CPU module now works under FreeBSD without the use of
3731 `libstatgrab', however SMP support is missing.
3732 * The default directories for the RRD files and the PID file now
3733 depend on the compile time setting of `localstatedir'.
3735 2005-11-15, Version 3.4.0 (Revision 236)
3736 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
3737 from gentoo's bugzilla for writing the patch.
3738 * The build dependency for librrd has been removed. Binaries built
3739 without librrd are client-only and will multicast their value as
3740 with the `-c' argument.
3741 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
3742 * The newly introduced `-f' switch prevents daemon initialization
3743 (forking, closing standard filehandles, etc.) Thanks to Alvaro
3744 Barcellos for this patch.
3746 2005-11-04, Version 3.3.0 (Revision 216)
3747 * New modules have been added:
3748 - `serial', for monitoring traffic on the serial interfaces
3749 - `nfs', for graphing NFS procedure calls
3750 - `tape', traffic from/to tape devices
3751 * The memory.rrd now accepts more than 4Gig of memory.
3753 2005-10-26, Version 3.2.0 (Revision 200)
3754 * Support for graphing the processes has been added (thanks to Lyonel
3756 * If reading from hddtemp fails collectd will increase the time
3757 between polls up to one day.
3758 * The init.d files have been improved.
3759 * Problems with the spec file have been fixed.
3761 2005-10-16, Version 3.1.0 (Revision 194)
3762 * Added the `setsid' syscall to the startup code.
3763 * Support for hddtemp has been added (thanks to Vincent Stehlé)
3765 2005-09-30, Version 3.0.0 (Revision 184)
3766 * The ability to send/receive data to/from the network (think
3767 multicast) has been added.
3768 * Modules have been split up into shared libraries can be loaded at
3769 runtime. The biggest advantage is that the core program doesn't need
3770 to be linked against an external library.
3771 * A patch by George Kargiotakis has been applied: It fixes the sensors
3772 behaviour then more than one sensor is being queried.
3774 2005-09-16, Version 2.1.0 (Revision 172)
3775 * A module for swap statistics has been added.
3777 2005-09-09, Version 2.0.0 (Revision 135)
3778 * Filenames can no longer be configured at program startup. The only
3779 options as of this version are the directory and ping hosts.
3780 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
3781 Soft-IRQ statistics are added to `System'.
3782 * Diskstats now collect read and write bytes, not sectors.
3783 * Ping statistics can now be collected for more than one host. There
3784 is no default any more: If no host is given no host will be pinged.
3785 * A self-written patch for libping has been applied so it builds
3788 2005-09-01, Version 1.8.1 (Revision 123)
3789 * Much improved configure-script: libraries and features may now be
3791 * More detailed warnings/error messages when RRD update fails.
3793 2005-08-29, Version 1.8.0:
3794 * Support for collecting disk statistics under Solaris.
3796 2005-08-25, Version 1.7.0:
3797 * Support for libstatgrab[1] for load, memory usage and network
3798 traffic. CPU- and disk-usage are not (yet) supported, since
3799 libstatgrab returns insufficient information. I will contact the
3801 * Improved the CPU-initialization code for Solaris. Apparently CPUs
3802 aren't necessarily counted linear which is now handled correctly.
3803 [1]: http://www.i-scream.org/libstatgrab/
3805 2005-08-21, Version 1.6.0:
3806 * Basic support for Solaris: System load and cpu-usage can be
3807 collected under Solaris, too. Other stats will follow later.
3808 * Many fixes in the autoconf-script
3809 * Collection/Museum scripts have been added under contrib/museum
3810 * collectd may now be started in unprivileged mode, though ping
3811 statistics will not work.
3813 2005-07-17, Version 1.5.1:
3814 * Diskstats-RRDs now use major/minor for naming. Some systems have
3815 weird strings as disk-names..
3817 2005-07-17, Version 1.5:
3818 * A new module, diskstats, has been added. It collects information
3819 about the disks and partitions.
3821 2005-07-11, Version 1.4.2:
3822 * The meminfo module has been changed to work with more platforms
3823 and/or kernel versions.
3825 2005-07-10, Version 1.4.1: Correct traffic stats
3826 * The traffic rrd-file is now created with DS-type `COUNTER' which I
3827 forgot to correct when I changed that module.
3829 2005-07-09, Version 1.4: More traffic stats
3830 * Traffic is now collected for all interfaces that can be found
3831 * Temperature-statistics are read from lm-sensors if available
3833 2005-07-08, Version 1.3: CPU stats
3834 * Collecting CPU statistics now
3836 2005-07-12, Version 1.2: Using syslog
3837 * collectd is now using the syslog facility to report errors, warnings
3839 * The default directory is now /var/db/collectd
3841 2005-07-10, Version 1.1: Minor changes
3842 * Nothing really useful to say ;)
3844 2005-07-09, Version 1.0: Initial Version
3845 * The following modules are provided:
