3089 * powerdns plugin: Set a timeout when reading data from the datagram
3090 socket. Handling of the “LocalSocket” option has been fixed. An
3091 incorrectly used “type” has been corrected. Thanks to Luke Heberling
3094 2009-07-18, Version 4.6.4
3095 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
3096 Díaz for fixing this bug.
3097 * collectd: A programming error has been fixed in the notification
3098 code. The bug may result in an assertion failure.
3099 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
3100 for reporting the bug.
3102 2009-06-02, Version 4.6.3
3103 * Build system, various plugins: Many build fixes for FreeBSD,
3104 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
3105 for many fixes and providing a build system for many platforms,
3106 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
3107 providing an OpenBSD system.
3108 * collectd: Two bugs with the threshold checking have been fixed. The
3109 first one prevented thresholds to be checked at all, the second one
3110 caused wrong behavior with the persistency option. Thanks to Andrés
3111 J. Díaz for fixing these problems.
3112 * collectd: Handling of the `Include' configuration option has been
3114 * battery plugin: Don't complain about a missing directory every
3116 * exec plugin: Allow executed programs to close STDERR. Thanks to
3117 Thorsten von Eicken for reporting this problem.
3118 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
3119 Tomasz Pala for the patch.
3120 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
3122 * memory plugin: Fix a potential problem under Solaris.

3127 * collectd: Some Solaris utility code has been improved.
3128 * filter subsystem: Allow `Chains' without default targets.
3129 * liboping: A patch to comply with strict aliasing rules has been
3131 * timediff match: Fix a typo: The match was registered with a wrong
3132 name which prevented this match to be used as documented. Thanks to
3133 Bruno Prémont for finding this problem.
3134 * bind plugin: Fix collection of the cached RR sets. The number of RR
3135 sets currently in the cache was collected as a counter value, which
3136 is nonsense. Thanks to Bruno Prémont for implementing this.
3137 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
3138 primarily BSDs, don't take it well and crash.
3139 * oracle plugin: Portability to 64 bit systems has been improved.
3140 * postgresql plugin: The default configuration has been improved.
3141 * rrdtool plugin: Fix a possible race condition: If the network plugin
3142 is brought and dispatches a value before the rrdtool plugin is
3143 initialized, the daemon may crash.
3145 2009-02-22, Version 4.6.1
3146 * collectd: Many documentation fixes.
3147 * Collectd::Unixsock: Error handling has been improved.
3148 * regex match: Don't link with the PCRE library.
3149 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
3150 for finding and fixing most of them.
3151 * ipmi plugin: Fix an off-by-one error which could cause segmentation
3152 faults. Thanks to Peter Holik for his patch.
3154 2009-02-16, Version 4.6.0
3155 * collectd: Added the `filter chain' infrastructure, which allows the
3156 user to use `matches' and `targets' to control value processing.
3157 * collectd: The new `-T' command line argument allows more in-depth
3158 testing of a configuration. Thanks to Doug MacEachern for the patch.
3159 * collectd-nagios: The Nagios integration command has been updated to
3160 use libcollectdclient. The `percentage' aggregation function has
3161 been added. Thanks to Fabian Linzberger for the patch.
3162 * libcollectdclient: A library which abstracts communication with the
3163 unixsock plugin for clients has been added.
3164 * regex match: Match values by their identifies using regular
3166 * timediff match: Match for values with an invalid timestamp.
3167 * value match: Select values by their data sources' values.
3168 * notification target: Create and dispatch a notification.
3169 * replace target: Replace parts of an identifier using regular
3171 * set target: Set (overwrite) entire parts of an identifier.
3172 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
3173 statistics, allowing very detailed name server statistics. Thanks to
3174 Bruno Prémont for this plugin.
3175 * cpu plugin: Report `interrupt' separately when using
3176 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
3177 example for native OpenBSD support, has been added. Thanks to Simon
3178 Kuhnle for the patch.
3179 * csv plugin: Make it possible to write values to STDOUT instead of
3180 files. This is meant for testing purposes mostly. The output written
3181 to STDOUT is compatible with the exec plugin. Thanks to Doug
3182 MacEachern for the patch.
3183 * curl plugin: This new plugin can be used to read web pages and parse
3184 them using the same mechanism that's used in the tail plugin.
3185 * dbi plugin: This new plugin allows you to connect to a variety of
3186 relational databases and use SQL to gather custom statistics from
3187 it. It is similar to the already existing PostgreSQL plugin but uses
3188 libdbi to communicate with the database(s).
3189 * interface plugin: Use the ignorelist framework when selecting /
3190 ignoring interfaces. This allows one to use regular expressions to
3191 select interfaces, too.
3192 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
3193 Thanks to Bruno Prémont for this patch.
3194 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
3196 * mysql plugin: Allow connecting to a database via the UNIX domain
3197 socket, too. Thanks to Mirko Buffoni for the patch.
3198 * network plugin: Further performance improvements for the receive
3199 code. This hopefully will help very large setups.
3200 * openvpn plugin: This new plugin collects statistics provided by the
3201 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
3202 * oracle plugin: This new plugin allows you to connect to an Oracle
3203 database and use SQL to gather custom statistics from it. It is
3204 similar to the already existing PostgreSQL plugin.
3205 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
3207 * perl plugin: Export the newly added plugin_write() to Perl plugins.
3208 * perl plugin: Added support for `notification meta data'.
3209 * perl plugin: Added support for the `filter chain' infrastructure by
3210 allowing plugins to register `matches' and `targets'.
3211 * postgresql plugin: The preferred configuration syntax has been
3212 updated to be in line with the syntax used by the new dbi and oracle
3213 plugins. The compatibility code for the old syntax is present.
3214 Support for the new `Result' blocks and the interval parameter has
3216 * processes plugin: Stacksize and virtual memory usage statistics have
3217 been added. Portability fixes.
3218 * rrdcached plugin: This new plugin uses the (still in development)
3219 RRD accelerator daemon, rrdcached. This daemon works very similar to
3220 the original rrdtool plugin of collectd, but adds some more nice
3222 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
3225 2009-05-09, Version 4.5.4
3226 * Build system, various plugins: Many build fixes for FreeBSD,
3227 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
3228 for many fixes and providing a build system for many platforms,
3229 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
3230 providing an OpenBSD system.
3231 * collectd: Fix a potential race condition when creating directories.
3232 * battery plugin: Don't complain about a missing directory every
3234 * dns plugin: Slight portability fixes.

3236 Thorsten von Eicken for reporting this problem.
3237 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
3238 Tomasz Pala for the patch.
3239 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
3241 * rrdtool plugin: Fix a possible race condition: If the network plugin
3242 is initialized and dispatches a value before the rrdtool plugin is
3243 initialized, the daemon may crash.
3244 * memory plugin: Fix a potential problem under Solaris.
3246 2009-02-22, Version 4.5.3
3247 * build system: The check for libupsclient even when `pkg-config' is
3249 * collectd: Fix error handling in the global cache.
3250 * Collectd::Unixsock: Error handling has been improved.
3251 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

3254 faults. Thanks to Peter Holik for his patch.
3255 * tcpconns plugin: An endianness problem has been fixed in the *BSD
3256 code. Thanks to "thated" for reporting this.
3258 2009-01-02, Version 4.5.2
3259 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3260 file may be in both locations, especially when the database was
3261 installed in a non-standard path. Thanks to Dusty Doris for
3263 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3264 Solaris, in the configure script automatically.
3265 * build system, tcpconns plugin: Check for `kvm_nlist' and
3266 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3267 library with similar functions to the BSD variant, but doesn't
3268 provide these necessary functions.
3269 * collectd.conf(5): Various fixes and clarifications.
3270 * collectd: Remove a GNUism (unnamed unions), thus improving
3272 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
3273 This solves portability problems, especially for Solaris.
3274 * dns plugin: Fix a portability problem with NetBSD.
3275 * filecount plugin: Fix an off-by-one error. This error may cause a
3277 * network plugin: Fix the handling of `type' in the network protocol.
3278 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3279 much larger buffer. This caused the `type' to be transferred much
3280 more often than necessary. In some cases, e. g. the `cpu' and
3281 `cpufreq' plugins being used at the same time, data may be corrupted
3282 in those files. Thanks to Bruno Prémont for debugging and reporting
3284 * processes plugin: Fix a possible segmentation fault when specifying
3285 invalid configuration options.
3286 * unixsock plugin: Make sure the initialization function is run only
3287 once. This resolves a file descriptor leak under systems which run
3288 the initialization more than once, such as Solaris.
3290 2008-10-16, Version 4.5.1
3291 * build system: Change `--enable-<plugin>' to abort with an error if
3292 dependencies are not met. Thanks to Bruno Prémont for the patch.
3293 Also, the poisoning of various string functions has been restricted
3295 * collectd: Fix a memory leak in the global value cache. With every
3296 *missing* value a couple of bytes would be leaked. Another memory
3297 leak in the configuration handling code has been fixed. Thanks to
3298 Niraj Tolia for reporting these issues.
3299 * collectd: Fix an off-by-one error in the ignorelist functionality.
3300 When using regular expressions, the last character would be missing,
3301 possibly matching differently from what one would expect.
3302 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3304 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3305 Linzberger for reporting the bug.
3306 * iptables plugin: Fix an off-by-one error. If a string was just one
3307 character too long, it was truncated instead of reporting an error.
3308 * network plugin: Fix a memory leak in the configuration handling
3309 code. Thanks to Niraj Tolia for reporting this issue.
3310 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
3311 * postgresql plugin: Don't reopen connection during reinitialization.
3312 This fixes a bug under Solaris and potentially other platforms.
3313 Missing calls to `PQclear' have been added, too. This fixes memory
3314 leaks. Thanks to ``Admin'' for reporting these bugs.
3315 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3317 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3318 problems with some `libc's. Thanks to Matthias Lay for reporting the
3321 2008-09-04, Version 4.5.0
3322 * collectd: Added the ability to flush certain identifiers.
3323 * collectd: The concept of `notification meta data' has been
3325 * filecount plugin: The new filecount plugin counts the number of
3326 files in a directory and its subdirectories.
3327 * ipmi plugin: Sensor names have been changed to ensure unique names.
3328 Notifications upon added and removed sensors can now be generated.
3329 * notify_desktop plugin: This new plugin sends notifications to the
3330 X desktop using the structure defined in the `Desktop Notification
3332 * notify_email plugin: This new plugin sends out notifications via
3333 email, using the `esmtp' library.
3334 * onewire plugin: The new experimental(!) onewire plugin reads values,
3335 such as temperatures, from sensors connected to the computer via the
3337 * perl plugin: Improved synchronized access to internal data structures
3338 and fixed a possible dead-lock.
3339 * perl plugin: Added the ability to flush certain identifiers and marked
3340 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3342 * perl plugin: Added the ability to configure Perl plugins.
3343 * postgresql plugin: The new postgresql plugin collects statistics
3344 about or from a PostgreSQL database.
3345 * processes plugin: The `ProcessMatch' option has been added.
3346 * rrdtool plugin: Implement throttling of the `update queue' to lessen
3348 * tcpconns plugin: This plugin has been ported to OpenBSD.
3349 * thermal plugin: The new thermal plugin collects system temperatures
3350 using Linux ACPI thermal zone data.
3352 2009-01-02, Version 4.4.5
3353 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3354 file may be in both locations, especially when the database was
3355 installed in a non-standard path. Thanks to Dusty Doris for
3357 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3358 Solaris, in the configure script automatically.
3359 * collectd.conf(5): Various fixes and clarifications.
3360 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
3361 portability problems, especially for Solaris.
3362 * dns plugin: Fix a portability problem with NetBSD.
3363 * network plugin: Fix the handling of `type' in the network protocol.
3364 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3365 much larger buffer. This caused the `type' to be transferred much
3366 more often than necessary. In some cases, e. g. the `cpu' and
3367 `cpufreq' plugins being used at the same time, data may be corrupted
3368 in those files. Thanks to Bruno Prémont for debugging and reporting
3370 * unixsock plugin: Make sure the initialization function is run only
3371 once. This resolves a file descriptor leak under systems which run
3372 the initialization more than once, such as Solaris.
3374 2008-10-16, Version 4.4.4
3375 * build system: Change `--enable-<plugin>' to abort with an error if
3376 dependencies are not met. Thanks to Bruno Prémont for the patch.
3377 Also, the poisoning of various string functions has been restricted
3379 * collectd: Fix a memory leak in the global value cache. With every
3380 *missing* value a couple of bytes would be leaked. Another memory
3381 leak in the configuration handling code has been fixed. Thanks to
3382 Niraj Tolia for reporting these issues.
3383 * collectd: Fix an off-by-one error in the ignorelist functionality.
3384 When using regular expressions, the last character would be missing,
3385 possibly matching differently from what one would expect.
3386 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3388 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3389 Linzberger for reporting the bug.

3394 problems with some `libc's. Thanks to Matthias Lay for reporting the
3397 2008-09-01, Version 4.4.3
3398 * collectd: Fix a memory leak in the threshold checking code.
3399 * memcached plugin: Fix a too short timeout and a related file
3401 * memory plugin: A typo in the libstatgrab code has been fixed.
3402 * snmp plugin: Fix a possible memory leak.
3404 2008-07-15, Version 4.4.2
3405 * build system: Use pkg-config to detect the upsclient library.
3406 * collectd: Try even harder to determine the endianness of the
3407 architecture collectd is being built on.
3408 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
3410 * dns plugin: Fix compilation errors with BIND versions 19991001
3412 * network plugin: Bugfix in the init routine: The init function
3413 cleared a buffer regardless of its contents. This could lead to lost
3414 values under Solaris.
3415 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
3416 * vserver plugin: Remove usage of the thread-unsafe `readdir'
3418 * wireless plugin: Work around incorrect noise and power values
3419 returned by some broken drivers.
3421 2008-06-03, Version 4.4.1
3422 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
3423 to kyrone for reporting this.
3424 * collectd: Fixed min/max output in notifications generated by
3426 * collectd-nagios: Fix the protocol used to communicate with the
3428 * perl plugin: Fail noisily, but don't shutdown the daemon, if
3429 initialization has errors. An issue with Perl 5.10 has been fixed.
3430 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
3431 René Rebe and Siegmund Gorr for reporting this.
3433 2008-05-06, Version 4.4.0
3434 * collectd: Internal code cleanups.
3435 * collectd: Added support for a `Flush' command in the unixsock and
3436 exec plugins. This command can be used to force a plugin (or all) to
3437 flush its values to disk.
3438 * collectd: Thresholds can now be configured to apply to one data
3439 source only, making it possible to configure different thresholds
3440 for each data source.
3441 * apache, nginx plugins: Added the possibility to disable host and/or
3443 * ascent plugin: The new ascent plugin reads and parses the statistics
3444 page of an Ascent server.

3450 sensor values via IPMI, the intelligent platform management
3452 * iptables plugin: The iptc library that is used by the iptables
3453 plugin has been added to the distribution, because it is not
3454 provided by all distributions and removed from at least one.

3456 authoritative or a recursing PowerDNS name server.
3457 * rrdtool plugin: The size of the files generated with the default
3458 configuration has been decreased.
3459 * tail plugin: The new tail plugin can be used to gather statistics by
3460 continuously reading from log files.
3461 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
3462 TeamSpeak2 server and collects statistics about the number of users
3463 and number of channels.
3464 * users plugin: Support for the statgrab library has been added.
3465 * vmem plugin: The new vmem plugin collects very detailed statistics
3466 about the virtual memory subsystem of Linux.

3490 if the libc expects it.
3491 * collectd: Error and warning messages have been improved.
3492 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3494 * apache plugin: Allocate new memory when reading a webpage instead of
3495 using a buffer of static size.
3496 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3498 * hddtemp plugin: Error and warning messages have been improved.

3504 * collectd: Fix handling of missing values in the global value cache.
3505 * collectd: Improved error messages when parsing the configuration.
3506 * sensors plugin: Fix temperature collection with libsensors4.
3507 * unixsock plugin: Fix mixed input and output operation on streams.
3508 * wireless plugin: Fix reading noise value.
3510 2008-03-05, Version 4.3.1
3511 * exec plugin: Set supplementary group IDs.
3513 + Use `memcpy' when constructing/parsing a package to avoid
3514 alignment problems on weird architectures, such as Sparc.
3515 + Translate doubles to/from the x86 byte representation to ensure
3516 cross-platform compatibility.
3517 * ping plugin: Correct the handling of the `TTL' setting.
3518 * swap plugin: Reapply a patch for Solaris.
3519 * tcpconns plugin: Portability improvements.
3521 2008-02-18, Version 4.3.0
3522 * collectd: Notifications have been added to the daemon. Notifications
3523 are status messages that may be associated with a data instance.
3524 * collectd: Threshold checking has been added to the daemon. This
3525 means that you can configure threshold values for each data
3526 instance. If this threshold is exceeded a notification will be
3528 * collectd: The new `FQDNLookup' option tells the daemon to use the
3529 full qualified domain name as the hostname, not just the host part
3530 es returned by `gethostname(2)'.
3531 * collectd: Support for more than one `TypesDB' file has been added.
3532 This is useful when one such file is included in a package but one
3533 wants to add custom type definitions.
3534 * collectd: The `Include' config option has been expanded to handle
3535 entire directories and shell wildcards.
3536 * collectdmon: The new `collectdmon' binary detects when collectd
3537 terminates and automatically restarts it again.
3538 * csv plugin: The CSV plugin is now able to store counter values as a
3539 rate, using the `StoreRates' configuration option.
3540 * exec plugin: Handling of notifications has been added and the
3541 ability to pass arguments to the executed programs has been added.
3542 * hddtemp plugin: The new `TranslateDevicename' option lets you
3543 disable the translation from device names to major-minor-numbers.
3544 * logfile plugin: Handling of notifications has been added.
3545 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3546 domain name lookups in this plugin.
3547 * perl plugin: Many internal changes added support for handling multiple
3548 threads making the plugin reasonably usable inside collectd. The API has
3549 been extended to support notifications and export global variables to
3550 Perl plugins; callbacks now have to be identified by name rather than a
3551 pointer to a subroutine. The plugin is no longer experimental.
3552 * uuid plugin: The new UUID plugin sets the hostname to an unique
3553 identifier for this host. This is meant for setups where each client
3554 may migrate to another physical host, possibly going through one or
3555 more name changes in the process. Thanks to Richard Jones from
3556 Red Hat's Emerging Technology group for this plugin.
3557 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3558 CPU, disk and network statistics about guest systems on the same
3559 physical server. Thanks to Richard Jones from Red Hat's Emerging
3560 Technology group for this plugin.
3562 2008-04-22, Version 4.2.7
3563 * build system: Improved detection of several libraries, especially if
3564 they are in non-standard paths.
3565 * build system: Portability fixes: Automatically define "_REENTRANT"
3566 if the libc expects it.
3567 * collectd: Error and warning messages have been improved.
3568 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3570 * apache plugin: Allocate new memory when reading a webpage instead of
3571 using a buffer of static size.
3572 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3574 * hddtemp plugin: Error and warning messages have been improved.
3575 * sensors plugin: Fix sensor collection for some chip types.
3577 2008-03-29, Version 4.2.6
3578 * collectd: Improved error messages when parsing the configuration.
3579 * sensors plugin: Fix temperature collection with libsensors4.
3580 * unixsock plugin: Fix mixed input and output operation on streams.
3581 * wireless plugin: Fix reading noise value.
3583 2008-03-04, Version 4.2.5
3584 * apache plugin: Improved initialization and error messages.
3585 * exec plugin: Set supplementary group IDs.
3587 + Create separate threads for reading from the socket and parsing
3588 and dispatching incoming packets. Versions prior to this may have
3589 problems in high-load situations, where the socket receive buffers
3590 overflows, resulting in gaps in the data.
3591 + Use `memcpy' when constructing/parsing a package to avoid
3592 alignment problems on weird architectures, such as Sparc.
3593 + Translate doubles to/from the x86 byte representation to ensure
3594 cross-platform compatibility.
3595 * ping plugin: Correct the handling of the `TTL' setting.
3596 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3597 * swap plugin: Reapply a patch for Solaris.
3598 * tcpconns plugin: Portability improvements.
3600 2008-01-21, Version 4.2.4
3601 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3602 the permission on the socket as documented in the manpage. Thanks to
3603 Evgeny Chukreev for fixing this issue.
3604 * collectd: The documentation has been improved.
3606 2007-12-28, Version 4.2.3
3607 * sensors plugin: Updated the plugin to build and work with version 3
3608 of the libsensors library.
3610 2007-12-15, Version 4.2.2
3611 * nginx plugin: Incorrect comparison of strings lead to a segfault
3612 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3614 * logfile plugin: The config option `Timestamp' was handled
3615 incorrectly and basically always active. Thanks to Luke Heberling
3618 2007-11-08, Version 4.2.1
3619 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3620 enabled on the host.
3621 * snmp plugin: Fix a memory leak.
3623 2007-10-27, Version 4.2.0
3624 * collectd: The new config option `Include' lets you include other
3625 configfiles and thus split up your config into smaller parts. This
3626 may be especially interesting for the snmp plugin to keep the data
3627 definitions separate from the host definitions.
3628 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3629 (number of connections, octets and packets for each service and
3630 destination). Thanks to Sebastian Harl for this plugin.
3631 * memcached plugin: The new `memcached' plugin connects to a memcached
3632 daemon process and collects statistics of this distributed caching
3633 system. Thanks to Antony Dovgal for contributing this plugin.
3634 * nginx plugin: The new `nginx' plugin reads the status page of an
3635 nginx daemon and saves the handled connections and requests.
3636 * perl plugin: Many changes, including the added `EnableDebugger'
3637 config option which lets you debug your Perl plugins more easily.
3638 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3639 be more thread-safe otherwise by locking calls to the library.
3640 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3641 correct the values returned by SNMP-agents. If a <data> block is
3642 defined as `table' the instance is now optional. The sequence number
3643 is used as the type-instance in this case. The new `InstancePrefix'
3644 option allows to add arbitrary prefixes to the type-instance.
3645 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3646 certain TCP connections and what state they're in. This can be used
3647 to see how many connections your FTP server has to handle or how
3648 many outgoing connections your mailserver has open.
3650 2008-01-11, Version 4.1.6
3651 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3652 the permission on the socket as documented in the manpage. Thanks to
3653 Evgeny Chukreev for fixing this issue.
3654 * collectd: The documentation has been improved.
3656 2007-12-27, Version 4.1.5
3657 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3659 * sensors plugin: Updated the plugin to build and work with version 3
3660 of the libsensors library.
3662 2007-11-08, Version 4.1.4
3663 * Build system: Improve detection of the rrd library, especially if
3664 it's in a non-standard location.
3665 * Build system: A bug when parsing the argument for
3666 `--with-libnetsnmp' has been fixed.
3667 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3668 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3669 a deadlock or delay when shutting down the daemon.
3670 * snmp plugin: Fix a memory leak.
3672 2007-10-24, Version 4.1.3
3673 * collectd: A build issue under Solaris has been resolved by renaming
3675 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3676 be more thread-safe otherwise by locking calls to the library.
3678 2007-09-28, Version 4.1.2
3679 * apcups plugin: Fix reporting of the `load percent' data.
3680 * wireless plugin: Correct the handling of cards returning signal and
3681 noise quality as percentage.
3682 * perl plugin: Fix a possible buffer overflow in get_module_name().
3683 * build system: Further improve the detection of libraries.
3684 * netlink plugin: Build issues under some older versions of the Linux
3685 includes (i. e. Debian Sarge) have been fixed.
3686 * snmp plugin: Fix a potential segfault when a host times out. Add
3687 support for the `timeticks' type.
3689 2007-09-12, Version 4.1.1
3690 * Build system: The detection of `libnetlink' has been improved.
3691 * collectd: The documentation has been fixed in numerous places.
3692 * exec plugin: Setting the group under which to run a program has been
3694 * collectd: The `sstrerror' function was improved to work correctly
3695 with the broken GNU version of `strerror_r'.
3696 * collectd: Write an error message to STDERR when loading of a plugin
3698 * apcups plugin: Fix the `types' used to submit the values: They still
3699 has an `apcups_' prefix which doesn't work anymore.
3700 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3701 whatever the client thinks is `now'..
3703 2007-09-01, Version 4.1.0
3704 * Build system: The build system has been changed to automatically
3705 disable all plugins, which are missing dependencies. The dependency
3706 checking has been removed from the plugins themselves to remove
3708 * Flexible interval: The interval of collected data is now sent along
3709 with the data itself over the network, so that the interval-settings
3710 of server and clients no longer needs to match.
3711 * netlink plugin: The new `netlink' plugin connects to the Linux
3712 kernel using a netlink socket and uses it to query information about
3713 interfaces, qdiscs and classes.
3714 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3715 to not block data collection.
3716 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3717 network devices, such as switches, routers, thermometers, rack
3718 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3720 * unixsock plugin: Added the `LISTVAL' command.
3721 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3722 of music played with xmms.
3724 2007-09-28, Version 4.0.9
3725 * apcups plugin: Fix reporting of the `load percent' data.
3726 * wireless plugin: Correct the handling of cards returning signal and
3727 noise quality as percentage.
3728 * perl plugin: Fix a possible buffer overflow in get_module_name().
3730 2007-09-12, Version 4.0.8
3731 * collectd: The `sstrerror' function was improved to work correctly
3732 with the broken GNU version of `strerror_r'.
3733 * collectd: Write an error message to STDERR when loading of a plugin
3735 * apcups plugin: Fix the `types' used to submit the values: They still
3736 has an `apcups_' prefix which doesn't work anymore.
3737 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3738 whatever the client thinks is `now'..
3740 2007-08-26, Version 4.0.7
3741 * documentation: Some typos have been fixed and some information has
3743 * build system: Many fixes for detecting libraries in unusual places,
3744 such as on RedHat systems. The affected libraries are `libcurl',
3745 `libmysql', and `libupsclient'.
3746 * network plugin: Allow the `Port' option to be specified as a number
3747 (i. e. without quotes).
3748 * nut plugin: A fix allows linking the nut plugin against
3749 libupsclient, version >= 2.2.0.
3750 * processes plugin: Fix a potential segmentation fault.
3752 2007-07-30, Version 4.0.6
3753 * sensors plugin: Fix the ignorelist functionality: Only the `type
3754 instance' was used to match against the list, but the documentation
3755 told otherwise. This release fixes the code, so it complies with the
3757 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3758 configuration messages will end up in the logging facility.
3759 * conrtib/fedora: The contributed specfile for Fedora has been
3762 2007-07-05, Version 4.0.5
3763 * Portability: More fixes for OpenBSD have been included.
3765 2007-06-24, Version 4.0.4
3766 * cpu plugin: Fixed the Solaris code.
3767 * dns plugin: Fixed a build issue for OpenBSD.
3768 * interface plugin: Fixed the Solaris code.
3769 * load plugin: Fixed the alternative `/proc' Linux code.
3770 * memory plugin: Fixed the Solaris code.
3771 * oconfig: Don't require `-lfl' anymore.
3773 2007-06-19, Version 4.0.3
3774 * cpu plugin: Fix the Darwin / Mac OS X code.
3775 * ping plugin: Use the return value of `getpid', not its address.
3776 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3777 initialized correctly.
3778 * configure: Added `--with-nan-emulation' to aid cross compilation.
3780 2007-06-12, Version 4.0.2
3781 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3782 they're given in numerically form.
3784 2007-06-07, Version 4.0.1
3785 * iptables plugin: A bug in the configuration routine has been fixed.
3786 Setting a comment in the configfile will no longer cause a
3789 2007-06-03, Version 4.0.0
3790 * collectd: The plugin-infrastructure has been changed to allow for
3791 more types of plugins, namely `write' and `log' plugins.
3792 * collectd: The read-function has been changed to read many plugins in
3793 parallel, using threads. Thus, plugins generally need to use
3794 thread-safe functions from now on.
3795 * collectd: The '-t' command line options allows to perform syntax tests
3796 of the configuration file and exit immediately.
3797 * csv plugin: The new `csv' plugin handles output to `comma separated
3799 * rrdtool plugin: The new `rrdtool' plugin handles output to
3800 RRD-files. Data can be cached to combine multiple updates into one
3801 write to increase IO-performance.
3802 * network plugin: The new `network' plugin handles IO via the network.
3803 It implements a different, much more extensible protocol which can
3804 combine many values in one packet, decreasing the number of UDP-
3805 packets being sent. It can read from and send to the network and
3806 with the appropriate configuration even forward packets to other
3808 * unixsock plugin: The new `unixsock' plugin provides an interface to
3809 communicate with the daemon while it is running. Right now the
3810 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3812 * perl plugin: The new `perl' plugin allows you to write extensions
3813 for collectd in the scripting-language Perl.
3814 * logfile plugin: The new `logfile' plugin writes logmessages to files
3815 or STDOUT or STDERR.
3816 * syslog plugin: The new `syslog' plugin sends logmessages to the
3817 system's syslog daemon.
3818 * entropy plugin: The new `entropy' plugin collects the amount of
3819 entropy currently being available to the system.
3820 * exec plugin: The new `exec' plugin forks child processes and reads
3821 back values provided by the forked processes.
3822 * iptables plugin: The new `iptables' plugin reads counters from
3823 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3825 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3826 to Peter Holik for contributing this plugin.
3827 * nut plugin: The new `nut' plugin connects the upsd of the `network
3828 ups tools' and reads information about the connected UPS.
3829 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3830 connections) field was added by Florent Monbillard.
3831 * collectd-nagios: The new `collectd-nagios' binary queries values
3832 from collectd, parses them and exits according to Nagios-standards.
3833 * manpages: The manpages have been improved a lot.
3835 2007-09-28, Version 3.11.7
3836 * wireless plugin: Correct the handling of cards returning signal and
3837 noise quality as percentage.
3839 2007-08-31, Version 3.11.6
3840 * processes plugin: Fix a potential segmentation fault.
3842 2007-05-29, Version 3.11.5
3843 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3844 * ntpd plugin: Fix a potential buffer overflow.
3845 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3846 were accounted as `zombies'.
3848 2007-04-10, Version 3.11.4
3849 * dns plugin: Change the order of includes to make the plugin compile
3852 2007-03-30, Version 3.11.3
3853 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3854 of the unused `COLLECT_KSTAT'.
3856 2007-02-11, Version 3.11.2
3857 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3858 NULL-pointer may have been passed to `printf' which causes a
3859 segfault with some libcs.
3861 2007-02-10, Version 3.11.1
3862 * df plugin: Some wrong defines have been fixed so the plugin works
3863 under Solaris again.
3864 * dns plugin: The usage of a struct has been fixed to work with
3866 * processes plugin: Some missing defines have been added so the plugin
3867 compiles cleanly under FreeBSD and presumably other UNIXes.
3869 2006-12-22, Version 3.11.0
3870 * collectd: The new command line option `-P' makes it easier for
3871 distributors to change the location of PID-files.
3872 * collectd: The daemon shuts down faster now which makes it easier to
3873 write init.d-scripts for it.
3874 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3875 caused problems every now and then.
3876 * df plugin: New config options allow to ignore certain mountpoints,
3877 filesystem types or devices.
3878 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3879 and interprets it. It collects traffic as well as qtype, opcode and
3881 * email plugin: Sebastian Harl has contributed this plugin which
3882 counts received mails in categories (e. g. ham, spam, virus), spam
3883 score (as given by SpamAssassin) and check types.
3884 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3885 uses `mbmon' to gather information from sensors on the motherboard.
3886 * processes plugin: Collect detailed statistics for configured
3887 processes, that's process and thread count, CPU usage, resident
3888 segment size and pagefaults.
3889 * multimeter plugin: Peter Holik contributed a new plugin which
3890 queries multimeters.
3891 * sensors plugin: Lubos Stanek has put much effort into improving this
3892 plugin, including `extended naming', collection of voltage values
3893 and the possibility to ignore certain values.
3895 2006-12-21, Version 3.10.4
3896 * Max Kellermann has identified a bug in the server routine: When
3897 opening a socket fails the daemon will (re)try opening the socket in
3898 an endless loop, ultimately leading to a `EMFILE' error.
3900 2006-11-04, Version 3.10.3
3901 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3902 ntpd's reply was sent in more than one packet, the buffer size was
3903 calculated incorrectly, resulting in the reading of uninitialized or
3906 2006-11-01, Version 3.10.2
3907 * The sample config file has been improved.
3908 * Errors in the manpages have been corrected.
3909 * The ping-plugin now adds hosts during initialization, not during
3910 startup. This speeds up startup when no network connectivity is
3911 available. Also, the hosts are being added later when the network is
3913 * Improved BSD-support for the df-plugin.
3914 * Fixed syntax errors in the swap-plugin for Mac OS X.
3915 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3917 * Don't disable the mysql-plugin if connecting to the database fails
3918 during initialization. Instead, try again in increasing intervals.
3920 2006-07-19, Version 3.10.1
3921 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3922 the apcups cannot be reached, unconnected sockets will pile up and
3923 eventually lead to `Too many open files' errors.
3925 2006-07-09, Version 3.10.0
3926 * The `disk' plugin has been ported to Darwin.
3927 * The `battery' plugin should work on many Apple computers now.
3928 * The `traffic' plugin can now ignore certain interfaces. Also,
3929 statistics for sent/received packets and errors have been added.
3930 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3931 to Anthony Gialluca for contributing this plugin and providing me
3932 with a test environment :)
3933 * A plugin for monitoring an NTP instance and the local clock drift
3936 2006-06-25, Version 3.9.4
3937 * The Solaris code in the `swap' plugin has been changed to reflect
3938 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3940 * The debugging system has been fixed to work with the Sun libc.
3941 * When built without librrd the variable `operating_mode' could be
3942 uninitialized. Thanks to David Elliot for reporting the bug.
3944 2006-06-01, Version 3.9.3
3945 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3946 operating systems also profit from the changes, but I wasn't able to
3948 * Changed the build system to find the netinet-includes under FreeBSD
3949 and therefore successfully build the `liboping' library there.
3951 2006-05-09, Version 3.9.2
3952 * Applied a patch to the `liboping' library. Due to a bug in the
3953 sequence checking the `ping' plugin stopped working after
3954 approximately 7.6 days.
3956 2006-05-09, Version 3.8.5
3957 * Applied a patch to the `liboping' library. Due to a bug in the
3958 sequence checking the `ping' plugin stopped working after
3959 approximately 7.6 days.
3961 2006-04-21, Version 3.9.1
3962 * Build issues with Solaris and possible other architectures have been
3964 * Problems when building the `apache'-plugin without `libcurl' have
3966 * A bug in the `ping' plugin has been fixed. Sorry folks.
3968 2006-04-02, Version 3.9.0
3969 * A plugin to monitor the Apache webserver has been added.
3970 <http://httpd.apache.org/>
3971 * A plugin to collect statistics about virtual servers using VServer.
3972 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
3974 * A plugin for wireless LAN cards has been added. It monitors signal
3975 strength, link quality and noise ratio..
3976 * A plugin for Apple hardware sensors has been added.
3977 * An option to compile collectd with different `step' and `heartbeat'
3978 settings has been added. The size of RRAs is no longer static but
3979 calculated based on the settings for `step' and `width'.
3980 * The `ping' plugin can now be configured to use a certain TTL.
3981 * A plugin to monitor the hardware sensors of Apple computers has been
3983 * The plugins `cpu', `memory', `processes' and `traffic' have been
3984 ported to Mach/Darwin (Mac OS X).
3985 * The `log mode' has been contributed by Christophe Kalt. It writes
3986 the data into text files rather than RRD files.
3988 2006-04-09, Version 3.8.4
3989 * Applied patch by Vincent Stehlé which improves the disk-name
3990 resolution in the `hddtemp' plugin for Linux systems.
3992 2006-04-02, Version 3.8.3
3993 * Applied a patch by James Byers: The MySQL plugin was not working
3994 with MySQL 5.0.2 or later.
3996 2006-03-14, Version 3.8.2
3997 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
3998 the GNU libc, because it points to `/etc/fstab' rather than
4001 2006-03-13, Version 3.8.1
4002 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
4003 * Fixes in the debian `postinst' and `init.d' scripts.
4005 2006-03-09, Version 3.8.0
4006 * The `ping' plugin no longer uses `libping' but a self written
4007 library named `liboping'. With this library it's possible to ping
4008 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
4010 2006-02-18, Version 3.7.2
4011 * A simple bug in the `battery' plugin has been fixed. It should now
4012 work with ACPI based batteries as well. Thanks to Sebastian for
4014 * Fixing a bug that prevented collectd to be built without librrd.
4015 Thanks to Werner Heuser for reporting it.
4017 2006-02-04, Version 3.7.1
4018 * The new network code has been improved to build with older versions
4020 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
4021 to Tommie Gannert for this patch.
4023 2006-01-30, Version 3.7.0
4024 * The `battery' plugin has been added. It collects information about
4026 * The MySQL plugin has been improved: It now writes two more RRD
4027 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
4028 * The `cpufreq' plugin now reads another file since the file it did
4029 read so far causes much overhead in the kernel. Also, you need root
4030 to read the old file, but not to read the new one.
4031 * The `hddtemp' plugin can now be configured to connect to another
4032 address and/or port than localhost.
4033 * The `df' plugin now prefers `statvfs' over `statfs'.
4034 * The network code has been rewritten. collectd now supports unicast
4035 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
4036 be set in the configfile.
4038 2006-01-24, Version 3.6.2
4039 * Due to a bug in the configfile handling collectd wouldn't start in
4040 client mode. This released fixes this.
4042 2006-01-20, Version 3.6.1
4043 * Due to a bug in `configure.in' all modules and the binary were
4044 linked against `libmysqlclient'. This issue is solved by this
4047 2006-01-17, Version 3.6.0
4048 * A config file has been added. This allows for loading only specific
4050 * A `df' plugin has been added.
4051 * A `mysql' plugin has been added.
4052 * The `ping' plugin doesn't entirely give up hope when a socket error
4053 occurred, but will back of and increase the intervals between tries.
4055 2006-01-21, Version 3.5.2
4056 * Fixed yet another bug in the signal handling.. Stupid typo..
4057 * Improved the ping plugin to not give up on socket errors (backport
4060 2005-12-18, Version 3.5.1
4061 * The PID-file is now deleted correctly when shutting down the daemon.
4062 * SIGINT and SIGTERM are now handled correctly.
4064 2005-12-16, Version 3.5.0 (Revision 326)
4065 * A bug in the `load' module under Solaris has been fixed.
4066 * The `users' module has been contributed by Sebastian Harl. It counts
4067 currently logged in users.
4068 * The CPU module now works under FreeBSD without the use of
4069 `libstatgrab', however SMP support is missing.
4070 * The default directories for the RRD files and the PID file now
4071 depend on the compile time setting of `localstatedir'.
4073 2005-11-15, Version 3.4.0 (Revision 236)
4074 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
4075 from gentoo's bugzilla for writing the patch.
4076 * The build dependency for librrd has been removed. Binaries built
4077 without librrd are client-only and will multicast their value as
4078 with the `-c' argument.
4079 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
4080 * The newly introduced `-f' switch prevents daemon initialization
4081 (forking, closing standard filehandles, etc.) Thanks to Alvaro
4082 Barcellos for this patch.
4084 2005-11-04, Version 3.3.0 (Revision 216)
4085 * New modules have been added:
4086 - `serial', for monitoring traffic on the serial interfaces
4087 - `nfs', for graphing NFS procedure calls
4088 - `tape', traffic from/to tape devices
4089 * The memory.rrd now accepts more than 4Gig of memory.
4091 2005-10-26, Version 3.2.0 (Revision 200)
4092 * Support for graphing the processes has been added (thanks to Lyonel
4094 * If reading from hddtemp fails collectd will increase the time
4095 between polls up to one day.
4096 * The init.d files have been improved.
4097 * Problems with the spec file have been fixed.
4099 2005-10-16, Version 3.1.0 (Revision 194)
4100 * Added the `setsid' syscall to the startup code.
4101 * Support for hddtemp has been added (thanks to Vincent Stehlé)
4103 2005-09-30, Version 3.0.0 (Revision 184)
4104 * The ability to send/receive data to/from the network (think
4105 multicast) has been added.
4106 * Modules have been split up into shared libraries can be loaded at
4107 runtime. The biggest advantage is that the core program doesn't need
4108 to be linked against an external library.
4109 * A patch by George Kargiotakis has been applied: It fixes the sensors
4110 behaviour then more than one sensor is being queried.
4112 2005-09-16, Version 2.1.0 (Revision 172)
4113 * A module for swap statistics has been added.
4115 2005-09-09, Version 2.0.0 (Revision 135)
4116 * Filenames can no longer be configured at program startup. The only
4117 options as of this version are the directory and ping hosts.
4118 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
4119 Soft-IRQ statistics are added to `System'.
4120 * Diskstats now collect read and write bytes, not sectors.
4121 * Ping statistics can now be collected for more than one host. There
4122 is no default any more: If no host is given no host will be pinged.
4123 * A self-written patch for libping has been applied so it builds
4126 2005-09-01, Version 1.8.1 (Revision 123)
4127 * Much improved configure-script: libraries and features may now be
4129 * More detailed warnings/error messages when RRD update fails.
4131 2005-08-29, Version 1.8.0:
4132 * Support for collecting disk statistics under Solaris.
4134 2005-08-25, Version 1.7.0:
4135 * Support for libstatgrab[1] for load, memory usage and network
4136 traffic. CPU- and disk-usage are not (yet) supported, since
4137 libstatgrab returns insufficient information. I will contact the
4139 * Improved the CPU-initialization code for Solaris. Apparently CPUs
4140 aren't necessarily counted linear which is now handled correctly.
4141 [1]: http://www.i-scream.org/libstatgrab/
4143 2005-08-21, Version 1.6.0:
4144 * Basic support for Solaris: System load and cpu-usage can be
4145 collected under Solaris, too. Other stats will follow later.
4146 * Many fixes in the autoconf-script
4147 * Collection/Museum scripts have been added under contrib/museum
4148 * collectd may now be started in unprivileged mode, though ping
4149 statistics will not work.
4151 2005-07-17, Version 1.5.1:
4152 * Diskstats-RRDs now use major/minor for naming. Some systems have
4153 weird strings as disk-names..
4155 2005-07-17, Version 1.5:
4156 * A new module, diskstats, has been added. It collects information
4157 about the disks and partitions.
4159 2005-07-11, Version 1.4.2:
4160 * The meminfo module has been changed to work with more platforms
4161 and/or kernel versions.
4163 2005-07-10, Version 1.4.1: Correct traffic stats
4164 * The traffic rrd-file is now created with DS-type `COUNTER' which I
4165 forgot to correct when I changed that module.
4167 2005-07-09, Version 1.4: More traffic stats
4168 * Traffic is now collected for all interfaces that can be found
4169 * Temperature-statistics are read from lm-sensors if available
4171 2005-07-08, Version 1.3: CPU stats
4172 * Collecting CPU statistics now
4174 2005-07-12, Version 1.2: Using syslog
4175 * collectd is now using the syslog facility to report errors, warnings
4177 * The default directory is now /var/db/collectd
4179 2005-07-10, Version 1.1: Minor changes
4180 * Nothing really useful to say ;)
4182 2005-07-09, Version 1.0: Initial Version
