3072 updated to the plugin only includes the shipped header files when it
3073 is linked with the shipped library, too.
3074 * java plugin: Delay creating the JVM until after the daemon has
3075 forked. The JVM internally creates threads that are lost when
3076 forking. This means that Java-based plugins are now configured
3077 during the init-phase, i. e. later than other plugins.
3078 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
3079 to Alan Pevec for the patch.
3080 * network plugin: Fix the handling of the “CacheFlush” option: The

3102 details have been added to the configuration summary. Support for
3103 libtool 2.2 has been added.
3104 * collectd: Two bugs with the threshold checking have been fixed. The
3105 first one prevented thresholds to be checked at all, the second one
3106 caused wrong behavior with the persistency option. Thanks to Andrés
3107 J. Díaz for fixing these problems.
3108 * collectd: Handling of the `Include' configuration option has been
3110 * rrdtool plugin: Make sure initialization is run only once. This
3111 resolves problems under Solaris and potentially other systems.
3112 Thanks to Amit Gupta for reporting this bug.
3113 * java plugin: Make it possible to use dots ('.') instead of slashes
3114 ('/') as the class separator. Thanks to Randy Rizun for pointing
3116 * swap plugin: A work-around for 32-bit Solaris has been added. Thanks
3117 to Doug MacEachern for the patch.

3127 Linux' file-system based caching framework. Thanks to Edward
3128 Konetzko for the patch.
3129 * gmond plugin: The new gmond plugin can receive and interpret
3130 multicast traffic from Ganglia's gmond daemon.
3131 * java plugin: The new java plugin exports the collectd API to Java,
3132 making it possible to write extensions to collectd in Java.
3133 * memcachec plugin: The new memcachec plugin queries data from a
3134 memcached daemon and parses it similar to the cURL plugin. Thanks to
3135 Doug MacEachern for the initial code.
3136 * memcached plugin: Support for connections over UNIX domain sockets
3137 has been added. Thanks to Franck Lombardi for the patch.

3150 plugin must no longer be a multiple of the global interval.
3151 * table plugin: The new Table plugin provides parsing for table-like
3152 structured files, such as many files beneath /proc.
3153 * ted plugin: The new TED plugin reads power consumption measurements
3154 from “The Energy Detective” (TED). Thanks to Eric Reed for this
3156 * onewire plugin: The new `Interval' option allows collecting
3157 information from OneWire sensors at arbitrary intervals.
3158 * ping plugin: Support for collecting the drop rate and standard
3159 deviation of round-trip times has been added.
3160 * uptime plugin: The new uptime plugin can collect the server's
3161 uptime. Thanks to Marco Chiappero for the patch.
3163 2009-09-10, Version 4.6.5
3164 * collectd: Remove old values when a cache entry is marked as missing.
3165 This way the “GETVAL” command of the UnixSock plugin doesn't return
3166 old, no longer valid values when this happens. Thanks to Andrés J.
3168 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
3169 to follow redirects. Thanks to Joey Hess for reporting this bug.
3170 * df plugin: Check the ignorelist before stating the file system,

3193 * Build system, various plugins: Many build fixes for FreeBSD,
3194 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
3195 for many fixes and providing a build system for many platforms,
3196 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
3197 providing an OpenBSD system.
3198 * collectd: Two bugs with the threshold checking have been fixed. The
3199 first one prevented thresholds to be checked at all, the second one
3200 caused wrong behavior with the persistency option. Thanks to Andrés
3201 J. Díaz for fixing these problems.
3202 * collectd: Handling of the `Include' configuration option has been

3218 * filter subsystem: Allow `Chains' without default targets.
3219 * liboping: A patch to comply with strict aliasing rules has been
3221 * timediff match: Fix a typo: The match was registered with a wrong
3222 name which prevented this match to be used as documented. Thanks to
3223 Bruno Prémont for finding this problem.
3224 * bind plugin: Fix collection of the cached RR sets. The number of RR
3225 sets currently in the cache was collected as a counter value, which
3226 is nonsense. Thanks to Bruno Prémont for implementing this.
3227 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
3228 primarily BSDs, don't take it well and crash.
3229 * oracle plugin: Portability to 64 bit systems has been improved.
3230 * postgresql plugin: The default configuration has been improved.
3231 * rrdtool plugin: Fix a possible race condition: If the network plugin

3240 for finding and fixing most of them.
3241 * ipmi plugin: Fix an off-by-one error which could cause segmentation
3242 faults. Thanks to Peter Holik for his patch.
3244 2009-02-16, Version 4.6.0
3245 * collectd: Added the `filter chain' infrastructure, which allows the
3246 user to use `matches' and `targets' to control value processing.
3247 * collectd: The new `-T' command line argument allows more in-depth
3248 testing of a configuration. Thanks to Doug MacEachern for the patch.
3249 * collectd-nagios: The Nagios integration command has been updated to
3250 use libcollectdclient. The `percentage' aggregation function has
3251 been added. Thanks to Fabian Linzberger for the patch.
3252 * libcollectdclient: A library which abstracts communication with the
3253 unixsock plugin for clients has been added.
3254 * regex match: Match values by their identifies using regular
3256 * timediff match: Match for values with an invalid timestamp.
3257 * value match: Select values by their data sources' values.

3263 statistics, allowing very detailed name server statistics. Thanks to
3264 Bruno Prémont for this plugin.
3265 * cpu plugin: Report `interrupt' separately when using
3266 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
3267 example for native OpenBSD support, has been added. Thanks to Simon
3268 Kuhnle for the patch.
3269 * csv plugin: Make it possible to write values to STDOUT instead of
3270 files. This is meant for testing purposes mostly. The output written
3271 to STDOUT is compatible with the exec plugin. Thanks to Doug
3272 MacEachern for the patch.
3273 * curl plugin: This new plugin can be used to read web pages and parse
3274 them using the same mechanism that's used in the tail plugin.
3275 * dbi plugin: This new plugin allows you to connect to a variety of
3276 relational databases and use SQL to gather custom statistics from
3277 it. It is similar to the already existing PostgreSQL plugin but uses
3278 libdbi to communicate with the database(s).
3279 * interface plugin: Use the ignorelist framework when selecting /
3280 ignoring interfaces. This allows one to use regular expressions to
3281 select interfaces, too.
3282 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
3283 Thanks to Bruno Prémont for this patch.
3284 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

3297 * perl plugin: Export the newly added plugin_write() to Perl plugins.
3298 * perl plugin: Added support for `notification meta data'.
3299 * perl plugin: Added support for the `filter chain' infrastructure by
3300 allowing plugins to register `matches' and `targets'.
3301 * postgresql plugin: The preferred configuration syntax has been
3302 updated to be in line with the syntax used by the new dbi and oracle
3303 plugins. The compatibility code for the old syntax is present.
3304 Support for the new `Result' blocks and the interval parameter has
3306 * processes plugin: Stacksize and virtual memory usage statistics have
3307 been added. Portability fixes.
3308 * rrdcached plugin: This new plugin uses the (still in development)
3309 RRD accelerator daemon, rrdcached. This daemon works very similar to
3310 the original rrdtool plugin of collectd, but adds some more nice
3312 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
3315 2009-05-09, Version 4.5.4
3316 * Build system, various plugins: Many build fixes for FreeBSD,
3317 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

3328 Tomasz Pala for the patch.
3329 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
3331 * rrdtool plugin: Fix a possible race condition: If the network plugin
3332 is initialized and dispatches a value before the rrdtool plugin is
3333 initialized, the daemon may crash.
3334 * memory plugin: Fix a potential problem under Solaris.
3336 2009-02-22, Version 4.5.3
3337 * build system: The check for libupsclient even when `pkg-config' is

3346 code. Thanks to "thated" for reporting this.
3348 2009-01-02, Version 4.5.2
3349 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3350 file may be in both locations, especially when the database was
3351 installed in a non-standard path. Thanks to Dusty Doris for
3353 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3354 Solaris, in the configure script automatically.
3355 * build system, tcpconns plugin: Check for `kvm_nlist' and
3356 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3357 library with similar functions to the BSD variant, but doesn't
3358 provide these necessary functions.
3359 * collectd.conf(5): Various fixes and clarifications.
3360 * collectd: Remove a GNUism (unnamed unions), thus improving
3362 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
3363 This solves portability problems, especially for Solaris.
3364 * dns plugin: Fix a portability problem with NetBSD.
3365 * filecount plugin: Fix an off-by-one error. This error may cause a
3367 * network plugin: Fix the handling of `type' in the network protocol.
3368 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3369 much larger buffer. This caused the `type' to be transferred much
3370 more often than necessary. In some cases, e. g. the `cpu' and
3371 `cpufreq' plugins being used at the same time, data may be corrupted
3372 in those files. Thanks to Bruno Prémont for debugging and reporting
3374 * processes plugin: Fix a possible segmentation fault when specifying
3375 invalid configuration options.
3376 * unixsock plugin: Make sure the initialization function is run only
3377 once. This resolves a file descriptor leak under systems which run
3378 the initialization more than once, such as Solaris.
3380 2008-10-16, Version 4.5.1
3381 * build system: Change `--enable-<plugin>' to abort with an error if
3382 dependencies are not met. Thanks to Bruno Prémont for the patch.
3383 Also, the poisoning of various string functions has been restricted
3385 * collectd: Fix a memory leak in the global value cache. With every
3386 *missing* value a couple of bytes would be leaked. Another memory
3387 leak in the configuration handling code has been fixed. Thanks to
3388 Niraj Tolia for reporting these issues.
3389 * collectd: Fix an off-by-one error in the ignorelist functionality.
3390 When using regular expressions, the last character would be missing,
3391 possibly matching differently from what one would expect.
3392 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3394 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3395 Linzberger for reporting the bug.
3396 * iptables plugin: Fix an off-by-one error. If a string was just one
3397 character too long, it was truncated instead of reporting an error.
3398 * network plugin: Fix a memory leak in the configuration handling
3399 code. Thanks to Niraj Tolia for reporting this issue.
3400 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
3401 * postgresql plugin: Don't reopen connection during reinitialization.
3402 This fixes a bug under Solaris and potentially other platforms.
3403 Missing calls to `PQclear' have been added, too. This fixes memory
3404 leaks. Thanks to ``Admin'' for reporting these bugs.
3405 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3407 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3408 problems with some `libc's. Thanks to Matthias Lay for reporting the
3411 2008-09-04, Version 4.5.0
3412 * collectd: Added the ability to flush certain identifiers.

3415 * filecount plugin: The new filecount plugin counts the number of
3416 files in a directory and its subdirectories.
3417 * ipmi plugin: Sensor names have been changed to ensure unique names.
3418 Notifications upon added and removed sensors can now be generated.
3419 * notify_desktop plugin: This new plugin sends notifications to the
3420 X desktop using the structure defined in the `Desktop Notification
3422 * notify_email plugin: This new plugin sends out notifications via
3423 email, using the `esmtp' library.
3424 * onewire plugin: The new experimental(!) onewire plugin reads values,
3425 such as temperatures, from sensors connected to the computer via the
3427 * perl plugin: Improved synchronized access to internal data structures
3428 and fixed a possible dead-lock.
3429 * perl plugin: Added the ability to flush certain identifiers and marked
3430 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3432 * perl plugin: Added the ability to configure Perl plugins.
3433 * postgresql plugin: The new postgresql plugin collects statistics
3434 about or from a PostgreSQL database.

3440 using Linux ACPI thermal zone data.
3442 2009-01-02, Version 4.4.5
3443 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3444 file may be in both locations, especially when the database was
3445 installed in a non-standard path. Thanks to Dusty Doris for
3447 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3448 Solaris, in the configure script automatically.
3449 * collectd.conf(5): Various fixes and clarifications.

3451 portability problems, especially for Solaris.
3452 * dns plugin: Fix a portability problem with NetBSD.
3453 * network plugin: Fix the handling of `type' in the network protocol.
3454 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3455 much larger buffer. This caused the `type' to be transferred much
3456 more often than necessary. In some cases, e. g. the `cpu' and
3457 `cpufreq' plugins being used at the same time, data may be corrupted
3458 in those files. Thanks to Bruno Prémont for debugging and reporting
3460 * unixsock plugin: Make sure the initialization function is run only

3506 * vserver plugin: Remove usage of the thread-unsafe `readdir'
3508 * wireless plugin: Work around incorrect noise and power values
3509 returned by some broken drivers.

3521 René Rebe and Siegmund Gorr for reporting this.
3523 2008-05-06, Version 4.4.0
3524 * collectd: Internal code cleanups.
3525 * collectd: Added support for a `Flush' command in the unixsock and
3526 exec plugins. This command can be used to force a plugin (or all) to
3527 flush its values to disk.
3528 * collectd: Thresholds can now be configured to apply to one data
3529 source only, making it possible to configure different thresholds
3530 for each data source.
3531 * apache, nginx plugins: Added the possibility to disable host and/or
3533 * ascent plugin: The new ascent plugin reads and parses the statistics
3534 page of an Ascent server.
3535 * cpu plugin: Support for the statgrab library has been added.
3536 * disk plugin: The possibility to ignore certain disks or collect only
3537 specific disks has been added.

3540 sensor values via IPMI, the intelligent platform management
3542 * iptables plugin: The iptc library that is used by the iptables
3543 plugin has been added to the distribution, because it is not
3544 provided by all distributions and removed from at least one.
3545 * powerdns plugin: The new powerdns plugin reads statistics from an
3546 authoritative or a recursing PowerDNS name server.
3547 * rrdtool plugin: The size of the files generated with the default
3548 configuration has been decreased.
3549 * tail plugin: The new tail plugin can be used to gather statistics by
3550 continuously reading from log files.
3551 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
3552 TeamSpeak2 server and collects statistics about the number of users
3553 and number of channels.
3554 * users plugin: Support for the statgrab library has been added.
3555 * vmem plugin: The new vmem plugin collects very detailed statistics
3556 about the virtual memory subsystem of Linux.
3558 2008-08-30, Version 4.3.4
3559 * Build system: Improved detection of and linking with the statgrab
3561 * collectd: Portability fixes, especially to determine endianness more
3563 * Various plugins: Fix format strings.
3564 * disk plugin: A fix for giving disks under Linux 2.4 the right names
3565 again has been applied.
3566 * memcached plugin: Fix a too short timeout and a related file
3568 * memory plugin: A typo in the libstatgrab code has been fixed.
3569 * network plugin: A fix in the initialization function solves problems
3571 * nginx plugin: A thread-unsafe function has been replaced.
3572 * vserver plugin: A thread-unsafe function has been replaced.
3573 * wireless plugin: A work-around for broken wireless drivers has been
3576 2008-04-22, Version 4.3.3
3577 * build system: Improved detection of several libraries, especially if
3578 they are in non-standard paths.
3579 * build system: Portability fixes: Automatically define "_REENTRANT"
3580 if the libc expects it.
3581 * collectd: Error and warning messages have been improved.
3582 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3584 * apache plugin: Allocate new memory when reading a webpage instead of
3585 using a buffer of static size.
3586 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3588 * hddtemp plugin: Error and warning messages have been improved.
3589 * sensors plugin: Fix sensor collection for some chip types.
3591 2008-03-29, Version 4.3.2
3592 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3593 `Persist' threshold options.
3594 * collectd: Fix handling of missing values in the global value cache.
3595 * collectd: Improved error messages when parsing the configuration.
3596 * sensors plugin: Fix temperature collection with libsensors4.
3597 * unixsock plugin: Fix mixed input and output operation on streams.
3598 * wireless plugin: Fix reading noise value.
3600 2008-03-05, Version 4.3.1
3601 * exec plugin: Set supplementary group IDs.
3603 + Use `memcpy' when constructing/parsing a package to avoid
3604 alignment problems on weird architectures, such as Sparc.
3605 + Translate doubles to/from the x86 byte representation to ensure
3606 cross-platform compatibility.
3607 * ping plugin: Correct the handling of the `TTL' setting.
3608 * swap plugin: Reapply a patch for Solaris.
3609 * tcpconns plugin: Portability improvements.
3611 2008-02-18, Version 4.3.0
3612 * collectd: Notifications have been added to the daemon. Notifications
3613 are status messages that may be associated with a data instance.
3614 * collectd: Threshold checking has been added to the daemon. This
3615 means that you can configure threshold values for each data
3616 instance. If this threshold is exceeded a notification will be
3618 * collectd: The new `FQDNLookup' option tells the daemon to use the
3619 full qualified domain name as the hostname, not just the host part
3620 es returned by `gethostname(2)'.
3621 * collectd: Support for more than one `TypesDB' file has been added.
3622 This is useful when one such file is included in a package but one
3623 wants to add custom type definitions.
3624 * collectd: The `Include' config option has been expanded to handle
3625 entire directories and shell wildcards.
3626 * collectdmon: The new `collectdmon' binary detects when collectd
3627 terminates and automatically restarts it again.
3628 * csv plugin: The CSV plugin is now able to store counter values as a
3629 rate, using the `StoreRates' configuration option.
3630 * exec plugin: Handling of notifications has been added and the
3631 ability to pass arguments to the executed programs has been added.
3632 * hddtemp plugin: The new `TranslateDevicename' option lets you
3633 disable the translation from device names to major-minor-numbers.
3634 * logfile plugin: Handling of notifications has been added.
3635 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3636 domain name lookups in this plugin.
3637 * perl plugin: Many internal changes added support for handling multiple
3638 threads making the plugin reasonably usable inside collectd. The API has
3639 been extended to support notifications and export global variables to
3640 Perl plugins; callbacks now have to be identified by name rather than a
3641 pointer to a subroutine. The plugin is no longer experimental.
3642 * uuid plugin: The new UUID plugin sets the hostname to an unique
3643 identifier for this host. This is meant for setups where each client
3644 may migrate to another physical host, possibly going through one or
3645 more name changes in the process. Thanks to Richard Jones from
3646 Red Hat's Emerging Technology group for this plugin.
3647 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3648 CPU, disk and network statistics about guest systems on the same
3649 physical server. Thanks to Richard Jones from Red Hat's Emerging
3650 Technology group for this plugin.
3652 2008-04-22, Version 4.2.7
3653 * build system: Improved detection of several libraries, especially if
3654 they are in non-standard paths.
3655 * build system: Portability fixes: Automatically define "_REENTRANT"
3656 if the libc expects it.
3657 * collectd: Error and warning messages have been improved.
3658 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3660 * apache plugin: Allocate new memory when reading a webpage instead of
3661 using a buffer of static size.
3662 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3664 * hddtemp plugin: Error and warning messages have been improved.
3665 * sensors plugin: Fix sensor collection for some chip types.
3667 2008-03-29, Version 4.2.6
3668 * collectd: Improved error messages when parsing the configuration.
3669 * sensors plugin: Fix temperature collection with libsensors4.
3670 * unixsock plugin: Fix mixed input and output operation on streams.
3671 * wireless plugin: Fix reading noise value.
3673 2008-03-04, Version 4.2.5
3674 * apache plugin: Improved initialization and error messages.
3675 * exec plugin: Set supplementary group IDs.
3677 + Create separate threads for reading from the socket and parsing
3678 and dispatching incoming packets. Versions prior to this may have
3679 problems in high-load situations, where the socket receive buffers
3680 overflows, resulting in gaps in the data.
3681 + Use `memcpy' when constructing/parsing a package to avoid
3682 alignment problems on weird architectures, such as Sparc.
3683 + Translate doubles to/from the x86 byte representation to ensure
3684 cross-platform compatibility.
3685 * ping plugin: Correct the handling of the `TTL' setting.
3686 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3687 * swap plugin: Reapply a patch for Solaris.
3688 * tcpconns plugin: Portability improvements.
3690 2008-01-21, Version 4.2.4
3691 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3692 the permission on the socket as documented in the manpage. Thanks to
3693 Evgeny Chukreev for fixing this issue.
3694 * collectd: The documentation has been improved.
3696 2007-12-28, Version 4.2.3
3697 * sensors plugin: Updated the plugin to build and work with version 3
3698 of the libsensors library.
3700 2007-12-15, Version 4.2.2
3701 * nginx plugin: Incorrect comparison of strings lead to a segfault
3702 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3704 * logfile plugin: The config option `Timestamp' was handled
3705 incorrectly and basically always active. Thanks to Luke Heberling
3708 2007-11-08, Version 4.2.1
3709 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3710 enabled on the host.
3711 * snmp plugin: Fix a memory leak.
3713 2007-10-27, Version 4.2.0
3714 * collectd: The new config option `Include' lets you include other
3715 configfiles and thus split up your config into smaller parts. This
3716 may be especially interesting for the snmp plugin to keep the data
3717 definitions separate from the host definitions.
3718 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3719 (number of connections, octets and packets for each service and
3720 destination). Thanks to Sebastian Harl for this plugin.
3721 * memcached plugin: The new `memcached' plugin connects to a memcached
3722 daemon process and collects statistics of this distributed caching
3723 system. Thanks to Antony Dovgal for contributing this plugin.
3724 * nginx plugin: The new `nginx' plugin reads the status page of an
3725 nginx daemon and saves the handled connections and requests.
3726 * perl plugin: Many changes, including the added `EnableDebugger'
3727 config option which lets you debug your Perl plugins more easily.
3728 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3729 be more thread-safe otherwise by locking calls to the library.
3730 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3731 correct the values returned by SNMP-agents. If a <data> block is
3732 defined as `table' the instance is now optional. The sequence number
3733 is used as the type-instance in this case. The new `InstancePrefix'
3734 option allows to add arbitrary prefixes to the type-instance.
3735 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3736 certain TCP connections and what state they're in. This can be used
3737 to see how many connections your FTP server has to handle or how
3738 many outgoing connections your mailserver has open.
3740 2008-01-11, Version 4.1.6
3741 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3742 the permission on the socket as documented in the manpage. Thanks to

3750 of the libsensors library.
3752 2007-11-08, Version 4.1.4
3753 * Build system: Improve detection of the rrd library, especially if
3754 it's in a non-standard location.
3755 * Build system: A bug when parsing the argument for
3756 `--with-libnetsnmp' has been fixed.
3757 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3758 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3759 a deadlock or delay when shutting down the daemon.
3760 * snmp plugin: Fix a memory leak.
3762 2007-10-24, Version 4.1.3
3763 * collectd: A build issue under Solaris has been resolved by renaming
3765 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3766 be more thread-safe otherwise by locking calls to the library.
3768 2007-09-28, Version 4.1.2
3769 * apcups plugin: Fix reporting of the `load percent' data.
3770 * wireless plugin: Correct the handling of cards returning signal and
3771 noise quality as percentage.
3772 * perl plugin: Fix a possible buffer overflow in get_module_name().
3773 * build system: Further improve the detection of libraries.
3774 * netlink plugin: Build issues under some older versions of the Linux
3775 includes (i. e. Debian Sarge) have been fixed.
3776 * snmp plugin: Fix a potential segfault when a host times out. Add
3777 support for the `timeticks' type.
3779 2007-09-12, Version 4.1.1
3780 * Build system: The detection of `libnetlink' has been improved.
3781 * collectd: The documentation has been fixed in numerous places.
3782 * exec plugin: Setting the group under which to run a program has been
3784 * collectd: The `sstrerror' function was improved to work correctly
3785 with the broken GNU version of `strerror_r'.
3786 * collectd: Write an error message to STDERR when loading of a plugin
3788 * apcups plugin: Fix the `types' used to submit the values: They still
3789 has an `apcups_' prefix which doesn't work anymore.
3790 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3791 whatever the client thinks is `now'..
3793 2007-09-01, Version 4.1.0
3794 * Build system: The build system has been changed to automatically
3795 disable all plugins, which are missing dependencies. The dependency
3796 checking has been removed from the plugins themselves to remove
3798 * Flexible interval: The interval of collected data is now sent along
3799 with the data itself over the network, so that the interval-settings
3800 of server and clients no longer needs to match.
3801 * netlink plugin: The new `netlink' plugin connects to the Linux
3802 kernel using a netlink socket and uses it to query information about
3803 interfaces, qdiscs and classes.
3804 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3805 to not block data collection.
3806 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3807 network devices, such as switches, routers, thermometers, rack
3808 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3810 * unixsock plugin: Added the `LISTVAL' command.
3811 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3812 of music played with xmms.
3814 2007-09-28, Version 4.0.9
3815 * apcups plugin: Fix reporting of the `load percent' data.
3816 * wireless plugin: Correct the handling of cards returning signal and
3817 noise quality as percentage.
3818 * perl plugin: Fix a possible buffer overflow in get_module_name().
3820 2007-09-12, Version 4.0.8
3821 * collectd: The `sstrerror' function was improved to work correctly
3822 with the broken GNU version of `strerror_r'.
3823 * collectd: Write an error message to STDERR when loading of a plugin
3825 * apcups plugin: Fix the `types' used to submit the values: They still
3826 has an `apcups_' prefix which doesn't work anymore.
3827 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3828 whatever the client thinks is `now'..
3830 2007-08-26, Version 4.0.7
3831 * documentation: Some typos have been fixed and some information has
3833 * build system: Many fixes for detecting libraries in unusual places,
3834 such as on RedHat systems. The affected libraries are `libcurl',
3835 `libmysql', and `libupsclient'.
3836 * network plugin: Allow the `Port' option to be specified as a number
3837 (i. e. without quotes).
3838 * nut plugin: A fix allows linking the nut plugin against
3839 libupsclient, version >= 2.2.0.
3840 * processes plugin: Fix a potential segmentation fault.
3842 2007-07-30, Version 4.0.6
3843 * sensors plugin: Fix the ignorelist functionality: Only the `type
3844 instance' was used to match against the list, but the documentation
3845 told otherwise. This release fixes the code, so it complies with the
3847 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3848 configuration messages will end up in the logging facility.
3849 * conrtib/fedora: The contributed specfile for Fedora has been
3852 2007-07-05, Version 4.0.5
3853 * Portability: More fixes for OpenBSD have been included.
3855 2007-06-24, Version 4.0.4
3856 * cpu plugin: Fixed the Solaris code.

3858 * interface plugin: Fixed the Solaris code.
3859 * load plugin: Fixed the alternative `/proc' Linux code.
3860 * memory plugin: Fixed the Solaris code.
3861 * oconfig: Don't require `-lfl' anymore.
3863 2007-06-19, Version 4.0.3
3864 * cpu plugin: Fix the Darwin / Mac OS X code.
3865 * ping plugin: Use the return value of `getpid', not its address.
3866 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3867 initialized correctly.
3868 * configure: Added `--with-nan-emulation' to aid cross compilation.
3870 2007-06-12, Version 4.0.2
3871 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3872 they're given in numerically form.
3874 2007-06-07, Version 4.0.1
3875 * iptables plugin: A bug in the configuration routine has been fixed.
3876 Setting a comment in the configfile will no longer cause a
3879 2007-06-03, Version 4.0.0
3880 * collectd: The plugin-infrastructure has been changed to allow for
3881 more types of plugins, namely `write' and `log' plugins.
3882 * collectd: The read-function has been changed to read many plugins in
3883 parallel, using threads. Thus, plugins generally need to use
3884 thread-safe functions from now on.
3885 * collectd: The '-t' command line options allows to perform syntax tests
3886 of the configuration file and exit immediately.
3887 * csv plugin: The new `csv' plugin handles output to `comma separated
3889 * rrdtool plugin: The new `rrdtool' plugin handles output to
3890 RRD-files. Data can be cached to combine multiple updates into one
3891 write to increase IO-performance.
3892 * network plugin: The new `network' plugin handles IO via the network.
3893 It implements a different, much more extensible protocol which can
3894 combine many values in one packet, decreasing the number of UDP-
3895 packets being sent. It can read from and send to the network and
3896 with the appropriate configuration even forward packets to other
3898 * unixsock plugin: The new `unixsock' plugin provides an interface to
3899 communicate with the daemon while it is running. Right now the
3900 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3902 * perl plugin: The new `perl' plugin allows you to write extensions
3903 for collectd in the scripting-language Perl.
3904 * logfile plugin: The new `logfile' plugin writes logmessages to files
3905 or STDOUT or STDERR.
3906 * syslog plugin: The new `syslog' plugin sends logmessages to the
3907 system's syslog daemon.
3908 * entropy plugin: The new `entropy' plugin collects the amount of
3909 entropy currently being available to the system.
3910 * exec plugin: The new `exec' plugin forks child processes and reads
3911 back values provided by the forked processes.
3912 * iptables plugin: The new `iptables' plugin reads counters from
3913 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3915 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3916 to Peter Holik for contributing this plugin.
3917 * nut plugin: The new `nut' plugin connects the upsd of the `network
3918 ups tools' and reads information about the connected UPS.
3919 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3920 connections) field was added by Florent Monbillard.
3921 * collectd-nagios: The new `collectd-nagios' binary queries values
3922 from collectd, parses them and exits according to Nagios-standards.
3923 * manpages: The manpages have been improved a lot.
3925 2007-09-28, Version 3.11.7
3926 * wireless plugin: Correct the handling of cards returning signal and
3927 noise quality as percentage.
3929 2007-08-31, Version 3.11.6
3930 * processes plugin: Fix a potential segmentation fault.
3932 2007-05-29, Version 3.11.5
3933 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3934 * ntpd plugin: Fix a potential buffer overflow.
3935 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3936 were accounted as `zombies'.
3938 2007-04-10, Version 3.11.4
3939 * dns plugin: Change the order of includes to make the plugin compile
3942 2007-03-30, Version 3.11.3
3943 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3944 of the unused `COLLECT_KSTAT'.
3946 2007-02-11, Version 3.11.2
3947 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3948 NULL-pointer may have been passed to `printf' which causes a
3949 segfault with some libcs.
3951 2007-02-10, Version 3.11.1
3952 * df plugin: Some wrong defines have been fixed so the plugin works
3953 under Solaris again.
3954 * dns plugin: The usage of a struct has been fixed to work with
3956 * processes plugin: Some missing defines have been added so the plugin
3957 compiles cleanly under FreeBSD and presumably other UNIXes.
3959 2006-12-22, Version 3.11.0
3960 * collectd: The new command line option `-P' makes it easier for
3961 distributors to change the location of PID-files.
3962 * collectd: The daemon shuts down faster now which makes it easier to
3963 write init.d-scripts for it.
3964 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3965 caused problems every now and then.
3966 * df plugin: New config options allow to ignore certain mountpoints,
3967 filesystem types or devices.
3968 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3969 and interprets it. It collects traffic as well as qtype, opcode and
3971 * email plugin: Sebastian Harl has contributed this plugin which
3972 counts received mails in categories (e. g. ham, spam, virus), spam
3973 score (as given by SpamAssassin) and check types.
3974 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3975 uses `mbmon' to gather information from sensors on the motherboard.
3976 * processes plugin: Collect detailed statistics for configured
3977 processes, that's process and thread count, CPU usage, resident
3978 segment size and pagefaults.
3979 * multimeter plugin: Peter Holik contributed a new plugin which
3980 queries multimeters.
3981 * sensors plugin: Lubos Stanek has put much effort into improving this
3982 plugin, including `extended naming', collection of voltage values
3983 and the possibility to ignore certain values.
3985 2006-12-21, Version 3.10.4
3986 * Max Kellermann has identified a bug in the server routine: When
3987 opening a socket fails the daemon will (re)try opening the socket in
3988 an endless loop, ultimately leading to a `EMFILE' error.
3990 2006-11-04, Version 3.10.3
3991 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3992 ntpd's reply was sent in more than one packet, the buffer size was
3993 calculated incorrectly, resulting in the reading of uninitialized or
3996 2006-11-01, Version 3.10.2
3997 * The sample config file has been improved.
3998 * Errors in the manpages have been corrected.
3999 * The ping-plugin now adds hosts during initialization, not during
4000 startup. This speeds up startup when no network connectivity is
4001 available. Also, the hosts are being added later when the network is
4003 * Improved BSD-support for the df-plugin.
4004 * Fixed syntax errors in the swap-plugin for Mac OS X.
4005 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
4007 * Don't disable the mysql-plugin if connecting to the database fails
4008 during initialization. Instead, try again in increasing intervals.
4010 2006-07-19, Version 3.10.1
4011 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
4012 the apcups cannot be reached, unconnected sockets will pile up and
4013 eventually lead to `Too many open files' errors.
4015 2006-07-09, Version 3.10.0
4016 * The `disk' plugin has been ported to Darwin.
4017 * The `battery' plugin should work on many Apple computers now.
4018 * The `traffic' plugin can now ignore certain interfaces. Also,
4019 statistics for sent/received packets and errors have been added.

4026 2006-06-25, Version 3.9.4
4027 * The Solaris code in the `swap' plugin has been changed to reflect
4028 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
4030 * The debugging system has been fixed to work with the Sun libc.
4031 * When built without librrd the variable `operating_mode' could be
4032 uninitialized. Thanks to David Elliot for reporting the bug.
4034 2006-06-01, Version 3.9.3
4035 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
4036 operating systems also profit from the changes, but I wasn't able to
4038 * Changed the build system to find the netinet-includes under FreeBSD
4039 and therefore successfully build the `liboping' library there.
4041 2006-05-09, Version 3.9.2
4042 * Applied a patch to the `liboping' library. Due to a bug in the
4043 sequence checking the `ping' plugin stopped working after
4044 approximately 7.6 days.
4046 2006-05-09, Version 3.8.5
4047 * Applied a patch to the `liboping' library. Due to a bug in the
4048 sequence checking the `ping' plugin stopped working after
4049 approximately 7.6 days.
4051 2006-04-21, Version 3.9.1
4052 * Build issues with Solaris and possible other architectures have been
4054 * Problems when building the `apache'-plugin without `libcurl' have

4059 * A plugin to monitor the Apache webserver has been added.
4060 <http://httpd.apache.org/>
4061 * A plugin to collect statistics about virtual servers using VServer.
4062 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
4064 * A plugin for wireless LAN cards has been added. It monitors signal
4065 strength, link quality and noise ratio..
4066 * A plugin for Apple hardware sensors has been added.
4067 * An option to compile collectd with different `step' and `heartbeat'
4068 settings has been added. The size of RRAs is no longer static but
4069 calculated based on the settings for `step' and `width'.
4070 * The `ping' plugin can now be configured to use a certain TTL.
4071 * A plugin to monitor the hardware sensors of Apple computers has been
4073 * The plugins `cpu', `memory', `processes' and `traffic' have been
4074 ported to Mach/Darwin (Mac OS X).
4075 * The `log mode' has been contributed by Christophe Kalt. It writes
4076 the data into text files rather than RRD files.
4078 2006-04-09, Version 3.8.4
4079 * Applied patch by Vincent Stehlé which improves the disk-name
4080 resolution in the `hddtemp' plugin for Linux systems.
4082 2006-04-02, Version 3.8.3
4083 * Applied a patch by James Byers: The MySQL plugin was not working
4084 with MySQL 5.0.2 or later.
4086 2006-03-14, Version 3.8.2
4087 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
4088 the GNU libc, because it points to `/etc/fstab' rather than
4091 2006-03-13, Version 3.8.1
4092 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
4093 * Fixes in the debian `postinst' and `init.d' scripts.
4095 2006-03-09, Version 3.8.0
4096 * The `ping' plugin no longer uses `libping' but a self written
4097 library named `liboping'. With this library it's possible to ping
4098 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
4100 2006-02-18, Version 3.7.2
4101 * A simple bug in the `battery' plugin has been fixed. It should now
4102 work with ACPI based batteries as well. Thanks to Sebastian for
4104 * Fixing a bug that prevented collectd to be built without librrd.
4105 Thanks to Werner Heuser for reporting it.
4107 2006-02-04, Version 3.7.1
4108 * The new network code has been improved to build with older versions

4111 to Tommie Gannert for this patch.
4113 2006-01-30, Version 3.7.0
4114 * The `battery' plugin has been added. It collects information about
4116 * The MySQL plugin has been improved: It now writes two more RRD
4117 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
4118 * The `cpufreq' plugin now reads another file since the file it did
4119 read so far causes much overhead in the kernel. Also, you need root
4120 to read the old file, but not to read the new one.
4121 * The `hddtemp' plugin can now be configured to connect to another
4122 address and/or port than localhost.
4123 * The `df' plugin now prefers `statvfs' over `statfs'.
4124 * The network code has been rewritten. collectd now supports unicast
4125 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
4126 be set in the configfile.
4128 2006-01-24, Version 3.6.2
4129 * Due to a bug in the configfile handling collectd wouldn't start in
4130 client mode. This released fixes this.
4132 2006-01-20, Version 3.6.1
4133 * Due to a bug in `configure.in' all modules and the binary were
4134 linked against `libmysqlclient'. This issue is solved by this
4137 2006-01-17, Version 3.6.0
4138 * A config file has been added. This allows for loading only specific
4140 * A `df' plugin has been added.
4141 * A `mysql' plugin has been added.
4142 * The `ping' plugin doesn't entirely give up hope when a socket error
4143 occurred, but will back of and increase the intervals between tries.
4145 2006-01-21, Version 3.5.2
4146 * Fixed yet another bug in the signal handling.. Stupid typo..
4147 * Improved the ping plugin to not give up on socket errors (backport
4150 2005-12-18, Version 3.5.1
4151 * The PID-file is now deleted correctly when shutting down the daemon.
4152 * SIGINT and SIGTERM are now handled correctly.
4154 2005-12-16, Version 3.5.0 (Revision 326)
4155 * A bug in the `load' module under Solaris has been fixed.
4156 * The `users' module has been contributed by Sebastian Harl. It counts
4157 currently logged in users.
4158 * The CPU module now works under FreeBSD without the use of
4159 `libstatgrab', however SMP support is missing.
4160 * The default directories for the RRD files and the PID file now
4161 depend on the compile time setting of `localstatedir'.
4163 2005-11-15, Version 3.4.0 (Revision 236)
4164 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
4165 from gentoo's bugzilla for writing the patch.
4166 * The build dependency for librrd has been removed. Binaries built
4167 without librrd are client-only and will multicast their value as
4168 with the `-c' argument.
4169 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
4170 * The newly introduced `-f' switch prevents daemon initialization
4171 (forking, closing standard filehandles, etc.) Thanks to Alvaro
4172 Barcellos for this patch.
4174 2005-11-04, Version 3.3.0 (Revision 216)
4175 * New modules have been added:
4176 - `serial', for monitoring traffic on the serial interfaces
4177 - `nfs', for graphing NFS procedure calls
4178 - `tape', traffic from/to tape devices
4179 * The memory.rrd now accepts more than 4Gig of memory.
4181 2005-10-26, Version 3.2.0 (Revision 200)
4182 * Support for graphing the processes has been added (thanks to Lyonel

4185 between polls up to one day.
4186 * The init.d files have been improved.
4187 * Problems with the spec file have been fixed.
4189 2005-10-16, Version 3.1.0 (Revision 194)
4190 * Added the `setsid' syscall to the startup code.
4191 * Support for hddtemp has been added (thanks to Vincent Stehlé)
4193 2005-09-30, Version 3.0.0 (Revision 184)
4194 * The ability to send/receive data to/from the network (think
4195 multicast) has been added.
4196 * Modules have been split up into shared libraries can be loaded at
4197 runtime. The biggest advantage is that the core program doesn't need
4198 to be linked against an external library.
4199 * A patch by George Kargiotakis has been applied: It fixes the sensors
4200 behaviour then more than one sensor is being queried.
4202 2005-09-16, Version 2.1.0 (Revision 172)
4203 * A module for swap statistics has been added.
4205 2005-09-09, Version 2.0.0 (Revision 135)
4206 * Filenames can no longer be configured at program startup. The only
4207 options as of this version are the directory and ping hosts.
4208 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
4209 Soft-IRQ statistics are added to `System'.
4210 * Diskstats now collect read and write bytes, not sectors.
4211 * Ping statistics can now be collected for more than one host. There
4212 is no default any more: If no host is given no host will be pinged.
4213 * A self-written patch for libping has been applied so it builds
4216 2005-09-01, Version 1.8.1 (Revision 123)
4217 * Much improved configure-script: libraries and features may now be
4219 * More detailed warnings/error messages when RRD update fails.
4221 2005-08-29, Version 1.8.0:
4222 * Support for collecting disk statistics under Solaris.
4224 2005-08-25, Version 1.7.0:
4225 * Support for libstatgrab[1] for load, memory usage and network
4226 traffic. CPU- and disk-usage are not (yet) supported, since
4227 libstatgrab returns insufficient information. I will contact the
4229 * Improved the CPU-initialization code for Solaris. Apparently CPUs
4230 aren't necessarily counted linear which is now handled correctly.
4231 [1]: http://www.i-scream.org/libstatgrab/
4233 2005-08-21, Version 1.6.0:
4234 * Basic support for Solaris: System load and cpu-usage can be
4235 collected under Solaris, too. Other stats will follow later.
4236 * Many fixes in the autoconf-script
4237 * Collection/Museum scripts have been added under contrib/museum
4238 * collectd may now be started in unprivileged mode, though ping
4239 statistics will not work.
4241 2005-07-17, Version 1.5.1:
4242 * Diskstats-RRDs now use major/minor for naming. Some systems have
4243 weird strings as disk-names..
4245 2005-07-17, Version 1.5:
4246 * A new module, diskstats, has been added. It collects information
4247 about the disks and partitions.
4249 2005-07-11, Version 1.4.2:
4250 * The meminfo module has been changed to work with more platforms
4251 and/or kernel versions.
4253 2005-07-10, Version 1.4.1: Correct traffic stats
4254 * The traffic rrd-file is now created with DS-type `COUNTER' which I
4255 forgot to correct when I changed that module.
4257 2005-07-09, Version 1.4: More traffic stats
4258 * Traffic is now collected for all interfaces that can be found
4259 * Temperature-statistics are read from lm-sensors if available
4261 2005-07-08, Version 1.3: CPU stats
4262 * Collecting CPU statistics now
4264 2005-07-12, Version 1.2: Using syslog
4265 * collectd is now using the syslog facility to report errors, warnings
4267 * The default directory is now /var/db/collectd
4269 2005-07-10, Version 1.1: Minor changes
4270 * Nothing really useful to say ;)
4272 2005-07-09, Version 1.0: Initial Version
4273 * The following modules are provided:
