3099 libtool 2.2 has been added.
3100 * collectd: Two bugs with the threshold checking have been fixed. The
3101 first one prevented thresholds to be checked at all, the second one
3102 caused wrong behavior with the persistency option. Thanks to Andrés
3103 J. Díaz for fixing these problems.
3104 * collectd: Handling of the `Include' configuration option has been
3106 * rrdtool plugin: Make sure initialization is run only once. This
3107 resolves problems under Solaris and potentially other systems.
3108 Thanks to Amit Gupta for reporting this bug.
3109 * java plugin: Make it possible to use dots ('.') instead of slashes
3110 ('/') as the class separator. Thanks to Randy Rizun for pointing

3159 2009-09-10, Version 4.6.5
3160 * collectd: Remove old values when a cache entry is marked as missing.
3161 This way the “GETVAL” command of the UnixSock plugin doesn't return
3162 old, no longer valid values when this happens. Thanks to Andrés J.
3164 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
3165 to follow redirects. Thanks to Joey Hess for reporting this bug.
3166 * df plugin: Check the ignorelist before stating the file system,

3190 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
3191 for many fixes and providing a build system for many platforms,
3192 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
3193 providing an OpenBSD system.
3194 * collectd: Two bugs with the threshold checking have been fixed. The
3195 first one prevented thresholds to be checked at all, the second one
3196 caused wrong behavior with the persistency option. Thanks to Andrés
3197 J. Díaz for fixing these problems.

3214 * filter subsystem: Allow `Chains' without default targets.
3215 * liboping: A patch to comply with strict aliasing rules has been
3217 * timediff match: Fix a typo: The match was registered with a wrong
3218 name which prevented this match to be used as documented. Thanks to
3219 Bruno Prémont for finding this problem.
3220 * bind plugin: Fix collection of the cached RR sets. The number of RR
3221 sets currently in the cache was collected as a counter value, which
3222 is nonsense. Thanks to Bruno Prémont for implementing this.
3223 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
3224 primarily BSDs, don't take it well and crash.
3225 * oracle plugin: Portability to 64 bit systems has been improved.
3226 * postgresql plugin: The default configuration has been improved.
3227 * rrdtool plugin: Fix a possible race condition: If the network plugin

3238 faults. Thanks to Peter Holik for his patch.
3240 2009-02-16, Version 4.6.0
3241 * collectd: Added the `filter chain' infrastructure, which allows the
3242 user to use `matches' and `targets' to control value processing.
3243 * collectd: The new `-T' command line argument allows more in-depth
3244 testing of a configuration. Thanks to Doug MacEachern for the patch.

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

3293 * perl plugin: Export the newly added plugin_write() to Perl plugins.
3294 * perl plugin: Added support for `notification meta data'.
3295 * perl plugin: Added support for the `filter chain' infrastructure by
3296 allowing plugins to register `matches' and `targets'.
3297 * postgresql plugin: The preferred configuration syntax has been
3298 updated to be in line with the syntax used by the new dbi and oracle
3299 plugins. The compatibility code for the old syntax is present.
3300 Support for the new `Result' blocks and the interval parameter has
3302 * processes plugin: Stacksize and virtual memory usage statistics have
3303 been added. Portability fixes.
3304 * rrdcached plugin: This new plugin uses the (still in development)
3305 RRD accelerator daemon, rrdcached. This daemon works very similar to
3306 the original rrdtool plugin of collectd, but adds some more nice
3308 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
3311 2009-05-09, Version 4.5.4
3312 * Build system, various plugins: Many build fixes for FreeBSD,
3313 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern

3325 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
3327 * rrdtool plugin: Fix a possible race condition: If the network plugin
3328 is initialized and dispatches a value before the rrdtool plugin is
3329 initialized, the daemon may crash.
3330 * memory plugin: Fix a potential problem under Solaris.
3332 2009-02-22, Version 4.5.3

3342 code. Thanks to "thated" for reporting this.
3344 2009-01-02, Version 4.5.2
3345 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3346 file may be in both locations, especially when the database was
3347 installed in a non-standard path. Thanks to Dusty Doris for
3349 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3350 Solaris, in the configure script automatically.
3351 * build system, tcpconns plugin: Check for `kvm_nlist' and
3352 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3353 library with similar functions to the BSD variant, but doesn't
3354 provide these necessary functions.
3355 * collectd.conf(5): Various fixes and clarifications.
3356 * collectd: Remove a GNUism (unnamed unions), thus improving

3361 * filecount plugin: Fix an off-by-one error. This error may cause a
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 * processes plugin: Fix a possible segmentation fault when specifying
3371 invalid configuration options.
3372 * unixsock plugin: Make sure the initialization function is run only
3373 once. This resolves a file descriptor leak under systems which run
3374 the initialization more than once, such as Solaris.
3376 2008-10-16, Version 4.5.1
3377 * build system: Change `--enable-<plugin>' to abort with an error if
3378 dependencies are not met. Thanks to Bruno Prémont for the patch.
3379 Also, the poisoning of various string functions has been restricted
3381 * collectd: Fix a memory leak in the global value cache. With every
3382 *missing* value a couple of bytes would be leaked. Another memory
3383 leak in the configuration handling code has been fixed. Thanks to
3384 Niraj Tolia for reporting these issues.
3385 * collectd: Fix an off-by-one error in the ignorelist functionality.
3386 When using regular expressions, the last character would be missing,
3387 possibly matching differently from what one would expect.
3388 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3390 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3391 Linzberger for reporting the bug.
3392 * iptables plugin: Fix an off-by-one error. If a string was just one
3393 character too long, it was truncated instead of reporting an error.
3394 * network plugin: Fix a memory leak in the configuration handling
3395 code. Thanks to Niraj Tolia for reporting this issue.
3396 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
3397 * postgresql plugin: Don't reopen connection during reinitialization.
3398 This fixes a bug under Solaris and potentially other platforms.
3399 Missing calls to `PQclear' have been added, too. This fixes memory
3400 leaks. Thanks to ``Admin'' for reporting these bugs.
3401 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3403 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3404 problems with some `libc's. Thanks to Matthias Lay for reporting the
3407 2008-09-04, Version 4.5.0
3408 * collectd: Added the ability to flush certain identifiers.

3412 files in a directory and its subdirectories.
3413 * ipmi plugin: Sensor names have been changed to ensure unique names.
3414 Notifications upon added and removed sensors can now be generated.
3415 * notify_desktop plugin: This new plugin sends notifications to the
3416 X desktop using the structure defined in the `Desktop Notification
3418 * notify_email plugin: This new plugin sends out notifications via
3419 email, using the `esmtp' library.
3420 * onewire plugin: The new experimental(!) onewire plugin reads values,
3421 such as temperatures, from sensors connected to the computer via the
3423 * perl plugin: Improved synchronized access to internal data structures
3424 and fixed a possible dead-lock.
3425 * perl plugin: Added the ability to flush certain identifiers and marked
3426 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3428 * perl plugin: Added the ability to configure Perl plugins.

3436 using Linux ACPI thermal zone data.
3438 2009-01-02, Version 4.4.5
3439 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3440 file may be in both locations, especially when the database was
3441 installed in a non-standard path. Thanks to Dusty Doris for
3443 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3444 Solaris, in the configure script automatically.
3445 * collectd.conf(5): Various fixes and clarifications.

3449 * network plugin: Fix the handling of `type' in the network protocol.
3450 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3451 much larger buffer. This caused the `type' to be transferred much
3452 more often than necessary. In some cases, e. g. the `cpu' and

3519 2008-05-06, Version 4.4.0
3520 * collectd: Internal code cleanups.
3521 * collectd: Added support for a `Flush' command in the unixsock and
3522 exec plugins. This command can be used to force a plugin (or all) to
3523 flush its values to disk.
3524 * collectd: Thresholds can now be configured to apply to one data
3525 source only, making it possible to configure different thresholds
3526 for each data source.
3527 * apache, nginx plugins: Added the possibility to disable host and/or
3529 * ascent plugin: The new ascent plugin reads and parses the statistics
3530 page of an Ascent server.
3531 * cpu plugin: Support for the statgrab library has been added.
3532 * disk plugin: The possibility to ignore certain disks or collect only
3533 specific disks has been added.

3540 provided by all distributions and removed from at least one.
3541 * powerdns plugin: The new powerdns plugin reads statistics from an
3542 authoritative or a recursing PowerDNS name server.
3543 * rrdtool plugin: The size of the files generated with the default
3544 configuration has been decreased.
3545 * tail plugin: The new tail plugin can be used to gather statistics by
3546 continuously reading from log files.
3547 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
3548 TeamSpeak2 server and collects statistics about the number of users
3549 and number of channels.
3550 * users plugin: Support for the statgrab library has been added.
3551 * vmem plugin: The new vmem plugin collects very detailed statistics
3552 about the virtual memory subsystem of Linux.
3554 2008-08-30, Version 4.3.4
3555 * Build system: Improved detection of and linking with the statgrab
3557 * collectd: Portability fixes, especially to determine endianness more
3559 * Various plugins: Fix format strings.
3560 * disk plugin: A fix for giving disks under Linux 2.4 the right names
3561 again has been applied.
3562 * memcached plugin: Fix a too short timeout and a related file
3564 * memory plugin: A typo in the libstatgrab code has been fixed.
3565 * network plugin: A fix in the initialization function solves problems
3567 * nginx plugin: A thread-unsafe function has been replaced.
3568 * vserver plugin: A thread-unsafe function has been replaced.
3569 * wireless plugin: A work-around for broken wireless drivers has been
3572 2008-04-22, Version 4.3.3
3573 * build system: Improved detection of several libraries, especially if
3574 they are in non-standard paths.
3575 * build system: Portability fixes: Automatically define "_REENTRANT"
3576 if the libc expects it.
3577 * collectd: Error and warning messages have been improved.
3578 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3580 * apache plugin: Allocate new memory when reading a webpage instead of
3581 using a buffer of static size.
3582 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3584 * hddtemp plugin: Error and warning messages have been improved.
3585 * sensors plugin: Fix sensor collection for some chip types.
3587 2008-03-29, Version 4.3.2
3588 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3589 `Persist' threshold options.
3590 * collectd: Fix handling of missing values in the global value cache.
3591 * collectd: Improved error messages when parsing the configuration.
3592 * sensors plugin: Fix temperature collection with libsensors4.
3593 * unixsock plugin: Fix mixed input and output operation on streams.
3594 * wireless plugin: Fix reading noise value.
3596 2008-03-05, Version 4.3.1
3597 * exec plugin: Set supplementary group IDs.
3599 + Use `memcpy' when constructing/parsing a package to avoid
3600 alignment problems on weird architectures, such as Sparc.
3601 + Translate doubles to/from the x86 byte representation to ensure
3602 cross-platform compatibility.
3603 * ping plugin: Correct the handling of the `TTL' setting.
3604 * swap plugin: Reapply a patch for Solaris.
3605 * tcpconns plugin: Portability improvements.
3607 2008-02-18, Version 4.3.0
3608 * collectd: Notifications have been added to the daemon. Notifications
3609 are status messages that may be associated with a data instance.
3610 * collectd: Threshold checking has been added to the daemon. This
3611 means that you can configure threshold values for each data
3612 instance. If this threshold is exceeded a notification will be
3614 * collectd: The new `FQDNLookup' option tells the daemon to use the
3615 full qualified domain name as the hostname, not just the host part
3616 es returned by `gethostname(2)'.
3617 * collectd: Support for more than one `TypesDB' file has been added.
3618 This is useful when one such file is included in a package but one
3619 wants to add custom type definitions.
3620 * collectd: The `Include' config option has been expanded to handle
3621 entire directories and shell wildcards.
3622 * collectdmon: The new `collectdmon' binary detects when collectd
3623 terminates and automatically restarts it again.
3624 * csv plugin: The CSV plugin is now able to store counter values as a
3625 rate, using the `StoreRates' configuration option.
3626 * exec plugin: Handling of notifications has been added and the
3627 ability to pass arguments to the executed programs has been added.
3628 * hddtemp plugin: The new `TranslateDevicename' option lets you
3629 disable the translation from device names to major-minor-numbers.
3630 * logfile plugin: Handling of notifications has been added.
3631 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3632 domain name lookups in this plugin.
3633 * perl plugin: Many internal changes added support for handling multiple
3634 threads making the plugin reasonably usable inside collectd. The API has
3635 been extended to support notifications and export global variables to
3636 Perl plugins; callbacks now have to be identified by name rather than a
3637 pointer to a subroutine. The plugin is no longer experimental.
3638 * uuid plugin: The new UUID plugin sets the hostname to an unique
3639 identifier for this host. This is meant for setups where each client
3640 may migrate to another physical host, possibly going through one or
3641 more name changes in the process. Thanks to Richard Jones from
3642 Red Hat's Emerging Technology group for this plugin.
3643 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3644 CPU, disk and network statistics about guest systems on the same
3645 physical server. Thanks to Richard Jones from Red Hat's Emerging
3646 Technology group for this plugin.
3648 2008-04-22, Version 4.2.7
3649 * build system: Improved detection of several libraries, especially if
3650 they are in non-standard paths.
3651 * build system: Portability fixes: Automatically define "_REENTRANT"
3652 if the libc expects it.
3653 * collectd: Error and warning messages have been improved.
3654 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3656 * apache plugin: Allocate new memory when reading a webpage instead of
3657 using a buffer of static size.
3658 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3660 * hddtemp plugin: Error and warning messages have been improved.
3661 * sensors plugin: Fix sensor collection for some chip types.
3663 2008-03-29, Version 4.2.6
3664 * collectd: Improved error messages when parsing the configuration.
3665 * sensors plugin: Fix temperature collection with libsensors4.
3666 * unixsock plugin: Fix mixed input and output operation on streams.
3667 * wireless plugin: Fix reading noise value.
3669 2008-03-04, Version 4.2.5
3670 * apache plugin: Improved initialization and error messages.
3671 * exec plugin: Set supplementary group IDs.
3673 + Create separate threads for reading from the socket and parsing
3674 and dispatching incoming packets. Versions prior to this may have
3675 problems in high-load situations, where the socket receive buffers
3676 overflows, resulting in gaps in the data.
3677 + Use `memcpy' when constructing/parsing a package to avoid
3678 alignment problems on weird architectures, such as Sparc.
3679 + Translate doubles to/from the x86 byte representation to ensure
3680 cross-platform compatibility.
3681 * ping plugin: Correct the handling of the `TTL' setting.
3682 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3683 * swap plugin: Reapply a patch for Solaris.
3684 * tcpconns plugin: Portability improvements.
3686 2008-01-21, Version 4.2.4
3687 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3688 the permission on the socket as documented in the manpage. Thanks to
3689 Evgeny Chukreev for fixing this issue.
3690 * collectd: The documentation has been improved.
3692 2007-12-28, Version 4.2.3
3693 * sensors plugin: Updated the plugin to build and work with version 3
3694 of the libsensors library.
3696 2007-12-15, Version 4.2.2
3697 * nginx plugin: Incorrect comparison of strings lead to a segfault
3698 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3700 * logfile plugin: The config option `Timestamp' was handled
3701 incorrectly and basically always active. Thanks to Luke Heberling
3704 2007-11-08, Version 4.2.1
3705 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3706 enabled on the host.
3707 * snmp plugin: Fix a memory leak.
3709 2007-10-27, Version 4.2.0
3710 * collectd: The new config option `Include' lets you include other
3711 configfiles and thus split up your config into smaller parts. This
3712 may be especially interesting for the snmp plugin to keep the data
3713 definitions separate from the host definitions.
3714 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3715 (number of connections, octets and packets for each service and
3716 destination). Thanks to Sebastian Harl for this plugin.
3717 * memcached plugin: The new `memcached' plugin connects to a memcached
3718 daemon process and collects statistics of this distributed caching
3719 system. Thanks to Antony Dovgal for contributing this plugin.
3720 * nginx plugin: The new `nginx' plugin reads the status page of an
3721 nginx daemon and saves the handled connections and requests.
3722 * perl plugin: Many changes, including the added `EnableDebugger'
3723 config option which lets you debug your Perl plugins more easily.
3724 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3725 be more thread-safe otherwise by locking calls to the library.
3726 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3727 correct the values returned by SNMP-agents. If a <data> block is
3728 defined as `table' the instance is now optional. The sequence number
3729 is used as the type-instance in this case. The new `InstancePrefix'
3730 option allows to add arbitrary prefixes to the type-instance.
3731 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3732 certain TCP connections and what state they're in. This can be used
3733 to see how many connections your FTP server has to handle or how
3734 many outgoing connections your mailserver has open.
3736 2008-01-11, Version 4.1.6
3737 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3738 the permission on the socket as documented in the manpage. Thanks to

3746 of the libsensors library.
3748 2007-11-08, Version 4.1.4
3749 * Build system: Improve detection of the rrd library, especially if
3750 it's in a non-standard location.
3751 * Build system: A bug when parsing the argument for
3752 `--with-libnetsnmp' has been fixed.
3753 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3754 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3755 a deadlock or delay when shutting down the daemon.
3756 * snmp plugin: Fix a memory leak.
3758 2007-10-24, Version 4.1.3
3759 * collectd: A build issue under Solaris has been resolved by renaming
3761 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3762 be more thread-safe otherwise by locking calls to the library.
3764 2007-09-28, Version 4.1.2
3765 * apcups plugin: Fix reporting of the `load percent' data.
3766 * wireless plugin: Correct the handling of cards returning signal and
3767 noise quality as percentage.
3768 * perl plugin: Fix a possible buffer overflow in get_module_name().
3769 * build system: Further improve the detection of libraries.
3770 * netlink plugin: Build issues under some older versions of the Linux
3771 includes (i. e. Debian Sarge) have been fixed.
3772 * snmp plugin: Fix a potential segfault when a host times out. Add
3773 support for the `timeticks' type.
3775 2007-09-12, Version 4.1.1
3776 * Build system: The detection of `libnetlink' has been improved.
3777 * collectd: The documentation has been fixed in numerous places.
3778 * exec plugin: Setting the group under which to run a program has been
3780 * collectd: The `sstrerror' function was improved to work correctly
3781 with the broken GNU version of `strerror_r'.
3782 * collectd: Write an error message to STDERR when loading of a plugin
3784 * apcups plugin: Fix the `types' used to submit the values: They still
3785 has an `apcups_' prefix which doesn't work anymore.
3786 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3787 whatever the client thinks is `now'..
3789 2007-09-01, Version 4.1.0
3790 * Build system: The build system has been changed to automatically
3791 disable all plugins, which are missing dependencies. The dependency
3792 checking has been removed from the plugins themselves to remove
3794 * Flexible interval: The interval of collected data is now sent along
3795 with the data itself over the network, so that the interval-settings
3796 of server and clients no longer needs to match.
3797 * netlink plugin: The new `netlink' plugin connects to the Linux
3798 kernel using a netlink socket and uses it to query information about
3799 interfaces, qdiscs and classes.
3800 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3801 to not block data collection.
3802 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3803 network devices, such as switches, routers, thermometers, rack
3804 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3806 * unixsock plugin: Added the `LISTVAL' command.
3807 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3808 of music played with xmms.
3810 2007-09-28, Version 4.0.9
3811 * apcups plugin: Fix reporting of the `load percent' data.
3812 * wireless plugin: Correct the handling of cards returning signal and
3813 noise quality as percentage.
3814 * perl plugin: Fix a possible buffer overflow in get_module_name().
3816 2007-09-12, Version 4.0.8
3817 * collectd: The `sstrerror' function was improved to work correctly
3818 with the broken GNU version of `strerror_r'.
3819 * collectd: Write an error message to STDERR when loading of a plugin
3821 * apcups plugin: Fix the `types' used to submit the values: They still
3822 has an `apcups_' prefix which doesn't work anymore.
3823 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3824 whatever the client thinks is `now'..
3826 2007-08-26, Version 4.0.7
3827 * documentation: Some typos have been fixed and some information has
3829 * build system: Many fixes for detecting libraries in unusual places,
3830 such as on RedHat systems. The affected libraries are `libcurl',
3831 `libmysql', and `libupsclient'.
3832 * network plugin: Allow the `Port' option to be specified as a number
3833 (i. e. without quotes).
3834 * nut plugin: A fix allows linking the nut plugin against
3835 libupsclient, version >= 2.2.0.
3836 * processes plugin: Fix a potential segmentation fault.
3838 2007-07-30, Version 4.0.6
3839 * sensors plugin: Fix the ignorelist functionality: Only the `type
3840 instance' was used to match against the list, but the documentation
3841 told otherwise. This release fixes the code, so it complies with the
3843 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3844 configuration messages will end up in the logging facility.
3845 * conrtib/fedora: The contributed specfile for Fedora has been
3848 2007-07-05, Version 4.0.5
3849 * Portability: More fixes for OpenBSD have been included.
3851 2007-06-24, Version 4.0.4
3852 * cpu plugin: Fixed the Solaris code.

3854 * interface plugin: Fixed the Solaris code.
3855 * load plugin: Fixed the alternative `/proc' Linux code.
3856 * memory plugin: Fixed the Solaris code.
3857 * oconfig: Don't require `-lfl' anymore.
3859 2007-06-19, Version 4.0.3
3860 * cpu plugin: Fix the Darwin / Mac OS X code.
3861 * ping plugin: Use the return value of `getpid', not its address.
3862 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3863 initialized correctly.
3864 * configure: Added `--with-nan-emulation' to aid cross compilation.
3866 2007-06-12, Version 4.0.2
3867 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3868 they're given in numerically form.
3870 2007-06-07, Version 4.0.1
3871 * iptables plugin: A bug in the configuration routine has been fixed.
3872 Setting a comment in the configfile will no longer cause a
3875 2007-06-03, Version 4.0.0
3876 * collectd: The plugin-infrastructure has been changed to allow for
3877 more types of plugins, namely `write' and `log' plugins.
3878 * collectd: The read-function has been changed to read many plugins in
3879 parallel, using threads. Thus, plugins generally need to use
3880 thread-safe functions from now on.
3881 * collectd: The '-t' command line options allows to perform syntax tests
3882 of the configuration file and exit immediately.
3883 * csv plugin: The new `csv' plugin handles output to `comma separated
3885 * rrdtool plugin: The new `rrdtool' plugin handles output to
3886 RRD-files. Data can be cached to combine multiple updates into one
3887 write to increase IO-performance.
3888 * network plugin: The new `network' plugin handles IO via the network.
3889 It implements a different, much more extensible protocol which can
3890 combine many values in one packet, decreasing the number of UDP-
3891 packets being sent. It can read from and send to the network and
3892 with the appropriate configuration even forward packets to other
3894 * unixsock plugin: The new `unixsock' plugin provides an interface to
3895 communicate with the daemon while it is running. Right now the
3896 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3898 * perl plugin: The new `perl' plugin allows you to write extensions
3899 for collectd in the scripting-language Perl.
3900 * logfile plugin: The new `logfile' plugin writes logmessages to files
3901 or STDOUT or STDERR.
3902 * syslog plugin: The new `syslog' plugin sends logmessages to the
3903 system's syslog daemon.
3904 * entropy plugin: The new `entropy' plugin collects the amount of
3905 entropy currently being available to the system.
3906 * exec plugin: The new `exec' plugin forks child processes and reads
3907 back values provided by the forked processes.
3908 * iptables plugin: The new `iptables' plugin reads counters from
3909 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3911 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3912 to Peter Holik for contributing this plugin.
3913 * nut plugin: The new `nut' plugin connects the upsd of the `network
3914 ups tools' and reads information about the connected UPS.
3915 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3916 connections) field was added by Florent Monbillard.
3917 * collectd-nagios: The new `collectd-nagios' binary queries values
3918 from collectd, parses them and exits according to Nagios-standards.
3919 * manpages: The manpages have been improved a lot.
3921 2007-09-28, Version 3.11.7
3922 * wireless plugin: Correct the handling of cards returning signal and
3923 noise quality as percentage.
3925 2007-08-31, Version 3.11.6
3926 * processes plugin: Fix a potential segmentation fault.
3928 2007-05-29, Version 3.11.5
3929 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3930 * ntpd plugin: Fix a potential buffer overflow.
3931 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3932 were accounted as `zombies'.
3934 2007-04-10, Version 3.11.4
3935 * dns plugin: Change the order of includes to make the plugin compile
3938 2007-03-30, Version 3.11.3
3939 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3940 of the unused `COLLECT_KSTAT'.
3942 2007-02-11, Version 3.11.2
3943 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3944 NULL-pointer may have been passed to `printf' which causes a
3945 segfault with some libcs.
3947 2007-02-10, Version 3.11.1
3948 * df plugin: Some wrong defines have been fixed so the plugin works
3949 under Solaris again.
3950 * dns plugin: The usage of a struct has been fixed to work with
3952 * processes plugin: Some missing defines have been added so the plugin
3953 compiles cleanly under FreeBSD and presumably other UNIXes.
3955 2006-12-22, Version 3.11.0
3956 * collectd: The new command line option `-P' makes it easier for
3957 distributors to change the location of PID-files.
3958 * collectd: The daemon shuts down faster now which makes it easier to
3959 write init.d-scripts for it.
3960 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3961 caused problems every now and then.
3962 * df plugin: New config options allow to ignore certain mountpoints,
3963 filesystem types or devices.
3964 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3965 and interprets it. It collects traffic as well as qtype, opcode and
3967 * email plugin: Sebastian Harl has contributed this plugin which
3968 counts received mails in categories (e. g. ham, spam, virus), spam
3969 score (as given by SpamAssassin) and check types.
3970 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3971 uses `mbmon' to gather information from sensors on the motherboard.
3972 * processes plugin: Collect detailed statistics for configured
3973 processes, that's process and thread count, CPU usage, resident
3974 segment size and pagefaults.
3975 * multimeter plugin: Peter Holik contributed a new plugin which
3976 queries multimeters.
3977 * sensors plugin: Lubos Stanek has put much effort into improving this
3978 plugin, including `extended naming', collection of voltage values
3979 and the possibility to ignore certain values.
3981 2006-12-21, Version 3.10.4
3982 * Max Kellermann has identified a bug in the server routine: When
3983 opening a socket fails the daemon will (re)try opening the socket in
3984 an endless loop, ultimately leading to a `EMFILE' error.
3986 2006-11-04, Version 3.10.3
3987 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3988 ntpd's reply was sent in more than one packet, the buffer size was
3989 calculated incorrectly, resulting in the reading of uninitialized or
3992 2006-11-01, Version 3.10.2
3993 * The sample config file has been improved.
3994 * Errors in the manpages have been corrected.
3995 * The ping-plugin now adds hosts during initialization, not during
3996 startup. This speeds up startup when no network connectivity is
3997 available. Also, the hosts are being added later when the network is
3999 * Improved BSD-support for the df-plugin.
4000 * Fixed syntax errors in the swap-plugin for Mac OS X.
4001 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
4003 * Don't disable the mysql-plugin if connecting to the database fails
4004 during initialization. Instead, try again in increasing intervals.
4006 2006-07-19, Version 3.10.1
4007 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
4008 the apcups cannot be reached, unconnected sockets will pile up and
4009 eventually lead to `Too many open files' errors.
4011 2006-07-09, Version 3.10.0
4012 * The `disk' plugin has been ported to Darwin.
4013 * The `battery' plugin should work on many Apple computers now.
4014 * The `traffic' plugin can now ignore certain interfaces. Also,
4015 statistics for sent/received packets and errors have been added.
4016 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
4017 to Anthony Gialluca for contributing this plugin and providing me
4018 with a test environment :)
4019 * A plugin for monitoring an NTP instance and the local clock drift
4022 2006-06-25, Version 3.9.4
4023 * The Solaris code in the `swap' plugin has been changed to reflect
4024 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
4026 * The debugging system has been fixed to work with the Sun libc.
4027 * When built without librrd the variable `operating_mode' could be
4028 uninitialized. Thanks to David Elliot for reporting the bug.
4030 2006-06-01, Version 3.9.3
4031 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
4032 operating systems also profit from the changes, but I wasn't able to
4034 * Changed the build system to find the netinet-includes under FreeBSD
4035 and therefore successfully build the `liboping' library there.
4037 2006-05-09, Version 3.9.2
4038 * Applied a patch to the `liboping' library. Due to a bug in the
4039 sequence checking the `ping' plugin stopped working after
4040 approximately 7.6 days.
4042 2006-05-09, Version 3.8.5
4043 * Applied a patch to the `liboping' library. Due to a bug in the
4044 sequence checking the `ping' plugin stopped working after
4045 approximately 7.6 days.
4047 2006-04-21, Version 3.9.1
4048 * Build issues with Solaris and possible other architectures have been
4050 * Problems when building the `apache'-plugin without `libcurl' have
4052 * A bug in the `ping' plugin has been fixed. Sorry folks.
4054 2006-04-02, Version 3.9.0
4055 * A plugin to monitor the Apache webserver has been added.
4056 <http://httpd.apache.org/>
4057 * A plugin to collect statistics about virtual servers using VServer.
4058 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
4060 * A plugin for wireless LAN cards has been added. It monitors signal
4061 strength, link quality and noise ratio..
4062 * A plugin for Apple hardware sensors has been added.
4063 * An option to compile collectd with different `step' and `heartbeat'
4064 settings has been added. The size of RRAs is no longer static but
4065 calculated based on the settings for `step' and `width'.
4066 * The `ping' plugin can now be configured to use a certain TTL.
4067 * A plugin to monitor the hardware sensors of Apple computers has been
4069 * The plugins `cpu', `memory', `processes' and `traffic' have been
4070 ported to Mach/Darwin (Mac OS X).
4071 * The `log mode' has been contributed by Christophe Kalt. It writes
4072 the data into text files rather than RRD files.
4074 2006-04-09, Version 3.8.4
4075 * Applied patch by Vincent Stehlé which improves the disk-name
4076 resolution in the `hddtemp' plugin for Linux systems.
4078 2006-04-02, Version 3.8.3
4079 * Applied a patch by James Byers: The MySQL plugin was not working
4080 with MySQL 5.0.2 or later.
4082 2006-03-14, Version 3.8.2
4083 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
4084 the GNU libc, because it points to `/etc/fstab' rather than
4087 2006-03-13, Version 3.8.1
4088 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
4089 * Fixes in the debian `postinst' and `init.d' scripts.
4091 2006-03-09, Version 3.8.0
4092 * The `ping' plugin no longer uses `libping' but a self written
4093 library named `liboping'. With this library it's possible to ping
4094 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
4096 2006-02-18, Version 3.7.2
4097 * A simple bug in the `battery' plugin has been fixed. It should now
4098 work with ACPI based batteries as well. Thanks to Sebastian for
4100 * Fixing a bug that prevented collectd to be built without librrd.
4101 Thanks to Werner Heuser for reporting it.
4103 2006-02-04, Version 3.7.1
4104 * The new network code has been improved to build with older versions
4106 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
4107 to Tommie Gannert for this patch.
4109 2006-01-30, Version 3.7.0
4110 * The `battery' plugin has been added. It collects information about
4112 * The MySQL plugin has been improved: It now writes two more RRD
4113 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
4114 * The `cpufreq' plugin now reads another file since the file it did
4115 read so far causes much overhead in the kernel. Also, you need root
4116 to read the old file, but not to read the new one.
4117 * The `hddtemp' plugin can now be configured to connect to another
4118 address and/or port than localhost.
4119 * The `df' plugin now prefers `statvfs' over `statfs'.
4120 * The network code has been rewritten. collectd now supports unicast
4121 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
4122 be set in the configfile.
4124 2006-01-24, Version 3.6.2
4125 * Due to a bug in the configfile handling collectd wouldn't start in
4126 client mode. This released fixes this.
4128 2006-01-20, Version 3.6.1
4129 * Due to a bug in `configure.in' all modules and the binary were
4130 linked against `libmysqlclient'. This issue is solved by this
4133 2006-01-17, Version 3.6.0
4134 * A config file has been added. This allows for loading only specific
4136 * A `df' plugin has been added.
4137 * A `mysql' plugin has been added.
4138 * The `ping' plugin doesn't entirely give up hope when a socket error
4139 occurred, but will back of and increase the intervals between tries.
4141 2006-01-21, Version 3.5.2
4142 * Fixed yet another bug in the signal handling.. Stupid typo..
4143 * Improved the ping plugin to not give up on socket errors (backport
4146 2005-12-18, Version 3.5.1
4147 * The PID-file is now deleted correctly when shutting down the daemon.
4148 * SIGINT and SIGTERM are now handled correctly.
4150 2005-12-16, Version 3.5.0 (Revision 326)
4151 * A bug in the `load' module under Solaris has been fixed.
4152 * The `users' module has been contributed by Sebastian Harl. It counts
4153 currently logged in users.
4154 * The CPU module now works under FreeBSD without the use of
4155 `libstatgrab', however SMP support is missing.
4156 * The default directories for the RRD files and the PID file now
4157 depend on the compile time setting of `localstatedir'.
4159 2005-11-15, Version 3.4.0 (Revision 236)
4160 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
4161 from gentoo's bugzilla for writing the patch.
4162 * The build dependency for librrd has been removed. Binaries built
4163 without librrd are client-only and will multicast their value as
4164 with the `-c' argument.
4165 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
4166 * The newly introduced `-f' switch prevents daemon initialization
4167 (forking, closing standard filehandles, etc.) Thanks to Alvaro
4168 Barcellos for this patch.
4170 2005-11-04, Version 3.3.0 (Revision 216)
4171 * New modules have been added:
4172 - `serial', for monitoring traffic on the serial interfaces
4173 - `nfs', for graphing NFS procedure calls
4174 - `tape', traffic from/to tape devices
4175 * The memory.rrd now accepts more than 4Gig of memory.
4177 2005-10-26, Version 3.2.0 (Revision 200)
4178 * Support for graphing the processes has been added (thanks to Lyonel
4180 * If reading from hddtemp fails collectd will increase the time
4181 between polls up to one day.
4182 * The init.d files have been improved.
4183 * Problems with the spec file have been fixed.
4185 2005-10-16, Version 3.1.0 (Revision 194)
4186 * Added the `setsid' syscall to the startup code.
4187 * Support for hddtemp has been added (thanks to Vincent Stehlé)
4189 2005-09-30, Version 3.0.0 (Revision 184)
4190 * The ability to send/receive data to/from the network (think
4191 multicast) has been added.
4192 * Modules have been split up into shared libraries can be loaded at
4193 runtime. The biggest advantage is that the core program doesn't need
4194 to be linked against an external library.
4195 * A patch by George Kargiotakis has been applied: It fixes the sensors
4196 behaviour then more than one sensor is being queried.
4198 2005-09-16, Version 2.1.0 (Revision 172)
4199 * A module for swap statistics has been added.
4201 2005-09-09, Version 2.0.0 (Revision 135)
4202 * Filenames can no longer be configured at program startup. The only
4203 options as of this version are the directory and ping hosts.
4204 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
4205 Soft-IRQ statistics are added to `System'.
4206 * Diskstats now collect read and write bytes, not sectors.
4207 * Ping statistics can now be collected for more than one host. There
4208 is no default any more: If no host is given no host will be pinged.
4209 * A self-written patch for libping has been applied so it builds
4212 2005-09-01, Version 1.8.1 (Revision 123)
4213 * Much improved configure-script: libraries and features may now be
4215 * More detailed warnings/error messages when RRD update fails.
4217 2005-08-29, Version 1.8.0:
4218 * Support for collecting disk statistics under Solaris.
4220 2005-08-25, Version 1.7.0:
4221 * Support for libstatgrab[1] for load, memory usage and network
4222 traffic. CPU- and disk-usage are not (yet) supported, since
4223 libstatgrab returns insufficient information. I will contact the
4225 * Improved the CPU-initialization code for Solaris. Apparently CPUs
4226 aren't necessarily counted linear which is now handled correctly.
4227 [1]: http://www.i-scream.org/libstatgrab/
4229 2005-08-21, Version 1.6.0:
4230 * Basic support for Solaris: System load and cpu-usage can be
4231 collected under Solaris, too. Other stats will follow later.
4232 * Many fixes in the autoconf-script
4233 * Collection/Museum scripts have been added under contrib/museum
4234 * collectd may now be started in unprivileged mode, though ping
4235 statistics will not work.
4237 2005-07-17, Version 1.5.1:
4238 * Diskstats-RRDs now use major/minor for naming. Some systems have
4239 weird strings as disk-names..
4241 2005-07-17, Version 1.5:
4242 * A new module, diskstats, has been added. It collects information
4243 about the disks and partitions.
4245 2005-07-11, Version 1.4.2:
4246 * The meminfo module has been changed to work with more platforms
4247 and/or kernel versions.
4249 2005-07-10, Version 1.4.1: Correct traffic stats
4250 * The traffic rrd-file is now created with DS-type `COUNTER' which I
4251 forgot to correct when I changed that module.
4253 2005-07-09, Version 1.4: More traffic stats
4254 * Traffic is now collected for all interfaces that can be found
4255 * Temperature-statistics are read from lm-sensors if available
4257 2005-07-08, Version 1.3: CPU stats
4258 * Collecting CPU statistics now
4260 2005-07-12, Version 1.2: Using syslog
4261 * collectd is now using the syslog facility to report errors, warnings
4263 * The default directory is now /var/db/collectd
4265 2005-07-10, Version 1.1: Minor changes
4266 * Nothing really useful to say ;)
4268 2005-07-09, Version 1.0: Initial Version
4269 * The following modules are provided:
