3110 * collectd: Remove old values when a cache entry is marked as missing.
3111 This way the “GETVAL” command of the UnixSock plugin doesn't return
3112 old, no longer valid values when this happens. Thanks to Andrés J.
3114 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
3115 to follow redirects. Thanks to Joey Hess for reporting this bug.

3140 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
3141 for many fixes and providing a build system for many platforms,
3142 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
3143 providing an OpenBSD system.
3144 * collectd: Two bugs with the threshold checking have been fixed. The
3145 first one prevented thresholds to be checked at all, the second one
3146 caused wrong behavior with the persistency option. Thanks to Andrés
3147 J. Díaz for fixing these problems.
3148 * collectd: Handling of the `Include' configuration option has been
3150 * battery plugin: Don't complain about a missing directory every

3165 * liboping: A patch to comply with strict aliasing rules has been
3167 * timediff match: Fix a typo: The match was registered with a wrong
3168 name which prevented this match to be used as documented. Thanks to
3169 Bruno Prémont for finding this problem.
3170 * bind plugin: Fix collection of the cached RR sets. The number of RR
3171 sets currently in the cache was collected as a counter value, which
3172 is nonsense. Thanks to Bruno Prémont for implementing this.
3173 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
3174 primarily BSDs, don't take it well and crash.
3175 * oracle plugin: Portability to 64 bit systems has been improved.
3176 * postgresql plugin: The default configuration has been improved.
3177 * rrdtool plugin: Fix a possible race condition: If the network plugin

3213 example for native OpenBSD support, has been added. Thanks to Simon
3214 Kuhnle for the patch.
3215 * csv plugin: Make it possible to write values to STDOUT instead of
3216 files. This is meant for testing purposes mostly. The output written
3217 to STDOUT is compatible with the exec plugin. Thanks to Doug
3218 MacEachern for the patch.
3219 * curl plugin: This new plugin can be used to read web pages and parse
3220 them using the same mechanism that's used in the tail plugin.
3221 * dbi plugin: This new plugin allows you to connect to a variety of
3222 relational databases and use SQL to gather custom statistics from
3223 it. It is similar to the already existing PostgreSQL plugin but uses
3224 libdbi to communicate with the database(s).
3225 * interface plugin: Use the ignorelist framework when selecting /
3226 ignoring interfaces. This allows one to use regular expressions to
3227 select interfaces, too.
3228 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
3229 Thanks to Bruno Prémont for this patch.
3230 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

3246 allowing plugins to register `matches' and `targets'.
3247 * postgresql plugin: The preferred configuration syntax has been
3248 updated to be in line with the syntax used by the new dbi and oracle
3249 plugins. The compatibility code for the old syntax is present.
3250 Support for the new `Result' blocks and the interval parameter has
3252 * processes plugin: Stacksize and virtual memory usage statistics have
3253 been added. Portability fixes.
3254 * rrdcached plugin: This new plugin uses the (still in development)
3255 RRD accelerator daemon, rrdcached. This daemon works very similar to
3256 the original rrdtool plugin of collectd, but adds some more nice
3258 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
3261 2009-05-09, Version 4.5.4
3262 * Build system, various plugins: Many build fixes for FreeBSD,

3275 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
3277 * rrdtool plugin: Fix a possible race condition: If the network plugin
3278 is initialized and dispatches a value before the rrdtool plugin is
3279 initialized, the daemon may crash.
3280 * memory plugin: Fix a potential problem under Solaris.
3282 2009-02-22, Version 4.5.3

3292 code. Thanks to "thated" for reporting this.
3294 2009-01-02, Version 4.5.2
3295 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3296 file may be in both locations, especially when the database was
3297 installed in a non-standard path. Thanks to Dusty Doris for
3299 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3300 Solaris, in the configure script automatically.
3301 * build system, tcpconns plugin: Check for `kvm_nlist' and
3302 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
3303 library with similar functions to the BSD variant, but doesn't
3304 provide these necessary functions.
3305 * collectd.conf(5): Various fixes and clarifications.
3306 * collectd: Remove a GNUism (unnamed unions), thus improving

3311 * filecount plugin: Fix an off-by-one error. This error may cause a
3313 * network plugin: Fix the handling of `type' in the network protocol.
3314 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3315 much larger buffer. This caused the `type' to be transferred much
3316 more often than necessary. In some cases, e. g. the `cpu' and
3317 `cpufreq' plugins being used at the same time, data may be corrupted
3318 in those files. Thanks to Bruno Prémont for debugging and reporting
3320 * processes plugin: Fix a possible segmentation fault when specifying
3321 invalid configuration options.
3322 * unixsock plugin: Make sure the initialization function is run only
3323 once. This resolves a file descriptor leak under systems which run
3324 the initialization more than once, such as Solaris.
3326 2008-10-16, Version 4.5.1
3327 * build system: Change `--enable-<plugin>' to abort with an error if
3328 dependencies are not met. Thanks to Bruno Prémont for the patch.
3329 Also, the poisoning of various string functions has been restricted
3331 * collectd: Fix a memory leak in the global value cache. With every
3332 *missing* value a couple of bytes would be leaked. Another memory
3333 leak in the configuration handling code has been fixed. Thanks to
3334 Niraj Tolia for reporting these issues.
3335 * collectd: Fix an off-by-one error in the ignorelist functionality.
3336 When using regular expressions, the last character would be missing,
3337 possibly matching differently from what one would expect.
3338 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
3340 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
3341 Linzberger for reporting the bug.
3342 * iptables plugin: Fix an off-by-one error. If a string was just one
3343 character too long, it was truncated instead of reporting an error.
3344 * network plugin: Fix a memory leak in the configuration handling
3345 code. Thanks to Niraj Tolia for reporting this issue.
3346 * perl plugin: Log an error message if bootstrapping `Collectd' fails.

3350 leaks. Thanks to ``Admin'' for reporting these bugs.
3351 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
3353 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
3354 problems with some `libc's. Thanks to Matthias Lay for reporting the

3364 Notifications upon added and removed sensors can now be generated.
3365 * notify_desktop plugin: This new plugin sends notifications to the
3366 X desktop using the structure defined in the `Desktop Notification
3368 * notify_email plugin: This new plugin sends out notifications via
3369 email, using the `esmtp' library.
3370 * onewire plugin: The new experimental(!) onewire plugin reads values,
3371 such as temperatures, from sensors connected to the computer via the
3373 * perl plugin: Improved synchronized access to internal data structures
3374 and fixed a possible dead-lock.
3375 * perl plugin: Added the ability to flush certain identifiers and marked
3376 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
3378 * perl plugin: Added the ability to configure Perl plugins.

3386 using Linux ACPI thermal zone data.
3388 2009-01-02, Version 4.4.5
3389 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3390 file may be in both locations, especially when the database was
3391 installed in a non-standard path. Thanks to Dusty Doris for
3393 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
3394 Solaris, in the configure script automatically.
3395 * collectd.conf(5): Various fixes and clarifications.

3397 portability problems, especially for Solaris.
3398 * dns plugin: Fix a portability problem with NetBSD.
3399 * network plugin: Fix the handling of `type' in the network protocol.
3400 Due to a programming mistake, only 4 or 8 bytes would be copied to a
3401 much larger buffer. This caused the `type' to be transferred much
3402 more often than necessary. In some cases, e. g. the `cpu' and
3403 `cpufreq' plugins being used at the same time, data may be corrupted
3404 in those files. Thanks to Bruno Prémont for debugging and reporting

3557 2008-02-18, Version 4.3.0
3558 * collectd: Notifications have been added to the daemon. Notifications
3559 are status messages that may be associated with a data instance.
3560 * collectd: Threshold checking has been added to the daemon. This
3561 means that you can configure threshold values for each data
3562 instance. If this threshold is exceeded a notification will be
3564 * collectd: The new `FQDNLookup' option tells the daemon to use the
3565 full qualified domain name as the hostname, not just the host part
3566 es returned by `gethostname(2)'.
3567 * collectd: Support for more than one `TypesDB' file has been added.
3568 This is useful when one such file is included in a package but one
3569 wants to add custom type definitions.
3570 * collectd: The `Include' config option has been expanded to handle
3571 entire directories and shell wildcards.
3572 * collectdmon: The new `collectdmon' binary detects when collectd
3573 terminates and automatically restarts it again.
3574 * csv plugin: The CSV plugin is now able to store counter values as a
3575 rate, using the `StoreRates' configuration option.
3576 * exec plugin: Handling of notifications has been added and the
3577 ability to pass arguments to the executed programs has been added.
3578 * hddtemp plugin: The new `TranslateDevicename' option lets you
3579 disable the translation from device names to major-minor-numbers.
3580 * logfile plugin: Handling of notifications has been added.
3581 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
3582 domain name lookups in this plugin.
3583 * perl plugin: Many internal changes added support for handling multiple
3584 threads making the plugin reasonably usable inside collectd. The API has
3585 been extended to support notifications and export global variables to
3586 Perl plugins; callbacks now have to be identified by name rather than a
3587 pointer to a subroutine. The plugin is no longer experimental.
3588 * uuid plugin: The new UUID plugin sets the hostname to an unique
3589 identifier for this host. This is meant for setups where each client
3590 may migrate to another physical host, possibly going through one or
3591 more name changes in the process. Thanks to Richard Jones from
3592 Red Hat's Emerging Technology group for this plugin.
3593 * libvirt: The new libvirt plugin uses the `libvirt' library to query
3594 CPU, disk and network statistics about guest systems on the same
3595 physical server. Thanks to Richard Jones from Red Hat's Emerging
3596 Technology group for this plugin.
3598 2008-04-22, Version 4.2.7
3599 * build system: Improved detection of several libraries, especially if
3600 they are in non-standard paths.
3601 * build system: Portability fixes: Automatically define "_REENTRANT"
3602 if the libc expects it.
3603 * collectd: Error and warning messages have been improved.
3604 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
3606 * apache plugin: Allocate new memory when reading a webpage instead of
3607 using a buffer of static size.
3608 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
3610 * hddtemp plugin: Error and warning messages have been improved.
3611 * sensors plugin: Fix sensor collection for some chip types.
3613 2008-03-29, Version 4.2.6
3614 * collectd: Improved error messages when parsing the configuration.
3615 * sensors plugin: Fix temperature collection with libsensors4.
3616 * unixsock plugin: Fix mixed input and output operation on streams.
3617 * wireless plugin: Fix reading noise value.
3619 2008-03-04, Version 4.2.5
3620 * apache plugin: Improved initialization and error messages.
3621 * exec plugin: Set supplementary group IDs.
3623 + Create separate threads for reading from the socket and parsing
3624 and dispatching incoming packets. Versions prior to this may have
3625 problems in high-load situations, where the socket receive buffers
3626 overflows, resulting in gaps in the data.
3627 + Use `memcpy' when constructing/parsing a package to avoid
3628 alignment problems on weird architectures, such as Sparc.
3629 + Translate doubles to/from the x86 byte representation to ensure
3630 cross-platform compatibility.
3631 * ping plugin: Correct the handling of the `TTL' setting.
3632 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
3633 * swap plugin: Reapply a patch for Solaris.
3634 * tcpconns plugin: Portability improvements.
3636 2008-01-21, Version 4.2.4
3637 * unixsock plugin: A bug in the unixsock plugin caused it not to set
3638 the permission on the socket as documented in the manpage. Thanks to
3639 Evgeny Chukreev for fixing this issue.
3640 * collectd: The documentation has been improved.
3642 2007-12-28, Version 4.2.3
3643 * sensors plugin: Updated the plugin to build and work with version 3
3644 of the libsensors library.
3646 2007-12-15, Version 4.2.2
3647 * nginx plugin: Incorrect comparison of strings lead to a segfault
3648 when using the plugin. Thanks to Saulius Grigaliunas for fixing
3650 * logfile plugin: The config option `Timestamp' was handled
3651 incorrectly and basically always active. Thanks to Luke Heberling
3654 2007-11-08, Version 4.2.1
3655 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
3656 enabled on the host.
3657 * snmp plugin: Fix a memory leak.
3659 2007-10-27, Version 4.2.0
3660 * collectd: The new config option `Include' lets you include other
3661 configfiles and thus split up your config into smaller parts. This
3662 may be especially interesting for the snmp plugin to keep the data
3663 definitions separate from the host definitions.
3664 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
3665 (number of connections, octets and packets for each service and
3666 destination). Thanks to Sebastian Harl for this plugin.
3667 * memcached plugin: The new `memcached' plugin connects to a memcached
3668 daemon process and collects statistics of this distributed caching
3669 system. Thanks to Antony Dovgal for contributing this plugin.
3670 * nginx plugin: The new `nginx' plugin reads the status page of an
3671 nginx daemon and saves the handled connections and requests.
3672 * perl plugin: Many changes, including the added `EnableDebugger'
3673 config option which lets you debug your Perl plugins more easily.
3674 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3675 be more thread-safe otherwise by locking calls to the library.
3676 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
3677 correct the values returned by SNMP-agents. If a <data> block is
3678 defined as `table' the instance is now optional. The sequence number
3679 is used as the type-instance in this case. The new `InstancePrefix'
3680 option allows to add arbitrary prefixes to the type-instance.
3681 * tcpconns plugin: The new `tcpconns' plugin collects the number of
3682 certain TCP connections and what state they're in. This can be used
3683 to see how many connections your FTP server has to handle or how
3684 many outgoing connections your mailserver has open.
3686 2008-01-11, Version 4.1.6
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 2007-12-27, Version 4.1.5
3693 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
3695 * sensors plugin: Updated the plugin to build and work with version 3
3696 of the libsensors library.
3698 2007-11-08, Version 4.1.4
3699 * Build system: Improve detection of the rrd library, especially if
3700 it's in a non-standard location.
3701 * Build system: A bug when parsing the argument for
3702 `--with-libnetsnmp' has been fixed.
3703 * collectd: Implement `strerror_r' if the libc doesn't provide it.
3704 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
3705 a deadlock or delay when shutting down the daemon.
3706 * snmp plugin: Fix a memory leak.
3708 2007-10-24, Version 4.1.3
3709 * collectd: A build issue under Solaris has been resolved by renaming
3711 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
3712 be more thread-safe otherwise by locking calls to the library.
3714 2007-09-28, Version 4.1.2
3715 * apcups plugin: Fix reporting of the `load percent' data.
3716 * wireless plugin: Correct the handling of cards returning signal and
3717 noise quality as percentage.
3718 * perl plugin: Fix a possible buffer overflow in get_module_name().
3719 * build system: Further improve the detection of libraries.
3720 * netlink plugin: Build issues under some older versions of the Linux
3721 includes (i. e. Debian Sarge) have been fixed.
3722 * snmp plugin: Fix a potential segfault when a host times out. Add
3723 support for the `timeticks' type.
3725 2007-09-12, Version 4.1.1
3726 * Build system: The detection of `libnetlink' has been improved.
3727 * collectd: The documentation has been fixed in numerous places.
3728 * exec plugin: Setting the group under which to run a program has been
3730 * collectd: The `sstrerror' function was improved to work correctly
3731 with the broken GNU version of `strerror_r'.
3732 * collectd: Write an error message to STDERR when loading of a plugin
3734 * apcups plugin: Fix the `types' used to submit the values: They still
3735 has an `apcups_' prefix which doesn't work anymore.
3736 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3737 whatever the client thinks is `now'..
3739 2007-09-01, Version 4.1.0
3740 * Build system: The build system has been changed to automatically
3741 disable all plugins, which are missing dependencies. The dependency
3742 checking has been removed from the plugins themselves to remove
3744 * Flexible interval: The interval of collected data is now sent along
3745 with the data itself over the network, so that the interval-settings
3746 of server and clients no longer needs to match.
3747 * netlink plugin: The new `netlink' plugin connects to the Linux
3748 kernel using a netlink socket and uses it to query information about
3749 interfaces, qdiscs and classes.
3750 * rrdtool plugin: The cache is now dumped to disk in an extra thread
3751 to not block data collection.
3752 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
3753 network devices, such as switches, routers, thermometers, rack
3754 monitoring servers, etc. The collectd-snmp(5) manpage documents this
3756 * unixsock plugin: Added the `LISTVAL' command.
3757 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
3758 of music played with xmms.
3760 2007-09-28, Version 4.0.9
3761 * apcups plugin: Fix reporting of the `load percent' data.
3762 * wireless plugin: Correct the handling of cards returning signal and
3763 noise quality as percentage.
3764 * perl plugin: Fix a possible buffer overflow in get_module_name().
3766 2007-09-12, Version 4.0.8
3767 * collectd: The `sstrerror' function was improved to work correctly
3768 with the broken GNU version of `strerror_r'.
3769 * collectd: Write an error message to STDERR when loading of a plugin
3771 * apcups plugin: Fix the `types' used to submit the values: They still
3772 has an `apcups_' prefix which doesn't work anymore.
3773 * rrdtool plugin: Create new RRD-files with the `begin' time set to
3774 whatever the client thinks is `now'..
3776 2007-08-26, Version 4.0.7
3777 * documentation: Some typos have been fixed and some information has
3779 * build system: Many fixes for detecting libraries in unusual places,
3780 such as on RedHat systems. The affected libraries are `libcurl',
3781 `libmysql', and `libupsclient'.
3782 * network plugin: Allow the `Port' option to be specified as a number
3783 (i. e. without quotes).
3784 * nut plugin: A fix allows linking the nut plugin against
3785 libupsclient, version >= 2.2.0.
3786 * processes plugin: Fix a potential segmentation fault.
3788 2007-07-30, Version 4.0.6
3789 * sensors plugin: Fix the ignorelist functionality: Only the `type
3790 instance' was used to match against the list, but the documentation
3791 told otherwise. This release fixes the code, so it complies with the
3793 * syslog plugin: Call `openlog' right when the plugin is loaded, so
3794 configuration messages will end up in the logging facility.
3795 * conrtib/fedora: The contributed specfile for Fedora has been
3798 2007-07-05, Version 4.0.5
3799 * Portability: More fixes for OpenBSD have been included.
3801 2007-06-24, Version 4.0.4
3802 * cpu plugin: Fixed the Solaris code.
3803 * dns plugin: Fixed a build issue for OpenBSD.
3804 * interface plugin: Fixed the Solaris code.
3805 * load plugin: Fixed the alternative `/proc' Linux code.
3806 * memory plugin: Fixed the Solaris code.
3807 * oconfig: Don't require `-lfl' anymore.
3809 2007-06-19, Version 4.0.3
3810 * cpu plugin: Fix the Darwin / Mac OS X code.
3811 * ping plugin: Use the return value of `getpid', not its address.
3812 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
3813 initialized correctly.
3814 * configure: Added `--with-nan-emulation' to aid cross compilation.
3816 2007-06-12, Version 4.0.2
3817 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
3818 they're given in numerically form.
3820 2007-06-07, Version 4.0.1
3821 * iptables plugin: A bug in the configuration routine has been fixed.
3822 Setting a comment in the configfile will no longer cause a
3825 2007-06-03, Version 4.0.0
3826 * collectd: The plugin-infrastructure has been changed to allow for
3827 more types of plugins, namely `write' and `log' plugins.
3828 * collectd: The read-function has been changed to read many plugins in
3829 parallel, using threads. Thus, plugins generally need to use
3830 thread-safe functions from now on.
3831 * collectd: The '-t' command line options allows to perform syntax tests
3832 of the configuration file and exit immediately.
3833 * csv plugin: The new `csv' plugin handles output to `comma separated
3835 * rrdtool plugin: The new `rrdtool' plugin handles output to
3836 RRD-files. Data can be cached to combine multiple updates into one
3837 write to increase IO-performance.
3838 * network plugin: The new `network' plugin handles IO via the network.
3839 It implements a different, much more extensible protocol which can
3840 combine many values in one packet, decreasing the number of UDP-
3841 packets being sent. It can read from and send to the network and
3842 with the appropriate configuration even forward packets to other
3844 * unixsock plugin: The new `unixsock' plugin provides an interface to
3845 communicate with the daemon while it is running. Right now the
3846 commands `GETVAL' and `PUTVAL' are implemented, but more are to
3848 * perl plugin: The new `perl' plugin allows you to write extensions
3849 for collectd in the scripting-language Perl.
3850 * logfile plugin: The new `logfile' plugin writes logmessages to files
3851 or STDOUT or STDERR.
3852 * syslog plugin: The new `syslog' plugin sends logmessages to the
3853 system's syslog daemon.
3854 * entropy plugin: The new `entropy' plugin collects the amount of
3855 entropy currently being available to the system.
3856 * exec plugin: The new `exec' plugin forks child processes and reads
3857 back values provided by the forked processes.
3858 * iptables plugin: The new `iptables' plugin reads counters from
3859 iptables rules. Thanks to Sjoerd van der Berg for contributing this
3861 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
3862 to Peter Holik for contributing this plugin.
3863 * nut plugin: The new `nut' plugin connects the upsd of the `network
3864 ups tools' and reads information about the connected UPS.
3865 * apache plugin: Support for lighttpd's `BusyServers' (aka.
3866 connections) field was added by Florent Monbillard.
3867 * collectd-nagios: The new `collectd-nagios' binary queries values
3868 from collectd, parses them and exits according to Nagios-standards.
3869 * manpages: The manpages have been improved a lot.
3871 2007-09-28, Version 3.11.7
3872 * wireless plugin: Correct the handling of cards returning signal and
3873 noise quality as percentage.
3875 2007-08-31, Version 3.11.6
3876 * processes plugin: Fix a potential segmentation fault.
3878 2007-05-29, Version 3.11.5
3879 * configure: Added `AC_SYS_LARGEFILE' for LFS.
3880 * ntpd plugin: Fix a potential buffer overflow.
3881 * processes plugin: Fix a bug when run under Linux 2.4. All processes
3882 were accounted as `zombies'.
3884 2007-04-10, Version 3.11.4
3885 * dns plugin: Change the order of includes to make the plugin compile
3888 2007-03-30, Version 3.11.3
3889 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
3890 of the unused `COLLECT_KSTAT'.
3892 2007-02-11, Version 3.11.2
3893 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
3894 NULL-pointer may have been passed to `printf' which causes a
3895 segfault with some libcs.
3897 2007-02-10, Version 3.11.1
3898 * df plugin: Some wrong defines have been fixed so the plugin works
3899 under Solaris again.
3900 * dns plugin: The usage of a struct has been fixed to work with
3902 * processes plugin: Some missing defines have been added so the plugin
3903 compiles cleanly under FreeBSD and presumably other UNIXes.
3905 2006-12-22, Version 3.11.0
3906 * collectd: The new command line option `-P' makes it easier for
3907 distributors to change the location of PID-files.
3908 * collectd: The daemon shuts down faster now which makes it easier to
3909 write init.d-scripts for it.
3910 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
3911 caused problems every now and then.
3912 * df plugin: New config options allow to ignore certain mountpoints,
3913 filesystem types or devices.
3914 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
3915 and interprets it. It collects traffic as well as qtype, opcode and
3917 * email plugin: Sebastian Harl has contributed this plugin which
3918 counts received mails in categories (e. g. ham, spam, virus), spam
3919 score (as given by SpamAssassin) and check types.
3920 * mbmon plugin: Flavio Stanchina has contributed this plugin which
3921 uses `mbmon' to gather information from sensors on the motherboard.
3922 * processes plugin: Collect detailed statistics for configured
3923 processes, that's process and thread count, CPU usage, resident
3924 segment size and pagefaults.
3925 * multimeter plugin: Peter Holik contributed a new plugin which
3926 queries multimeters.
3927 * sensors plugin: Lubos Stanek has put much effort into improving this
3928 plugin, including `extended naming', collection of voltage values
3929 and the possibility to ignore certain values.
3931 2006-12-21, Version 3.10.4
3932 * Max Kellermann has identified a bug in the server routine: When
3933 opening a socket fails the daemon will (re)try opening the socket in
3934 an endless loop, ultimately leading to a `EMFILE' error.
3936 2006-11-04, Version 3.10.3
3937 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
3938 ntpd's reply was sent in more than one packet, the buffer size was
3939 calculated incorrectly, resulting in the reading of uninitialized or
3942 2006-11-01, Version 3.10.2
3943 * The sample config file has been improved.
3944 * Errors in the manpages have been corrected.
3945 * The ping-plugin now adds hosts during initialization, not during
3946 startup. This speeds up startup when no network connectivity is
3947 available. Also, the hosts are being added later when the network is
3949 * Improved BSD-support for the df-plugin.
3950 * Fixed syntax errors in the swap-plugin for Mac OS X.
3951 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
3953 * Don't disable the mysql-plugin if connecting to the database fails
3954 during initialization. Instead, try again in increasing intervals.
3956 2006-07-19, Version 3.10.1
3957 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
3958 the apcups cannot be reached, unconnected sockets will pile up and
3959 eventually lead to `Too many open files' errors.
3961 2006-07-09, Version 3.10.0
3962 * The `disk' plugin has been ported to Darwin.
3963 * The `battery' plugin should work on many Apple computers now.
3964 * The `traffic' plugin can now ignore certain interfaces. Also,
3965 statistics for sent/received packets and errors have been added.
3966 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
3967 to Anthony Gialluca for contributing this plugin and providing me
3968 with a test environment :)
3969 * A plugin for monitoring an NTP instance and the local clock drift
3972 2006-06-25, Version 3.9.4
3973 * The Solaris code in the `swap' plugin has been changed to reflect
3974 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
3976 * The debugging system has been fixed to work with the Sun libc.
3977 * When built without librrd the variable `operating_mode' could be
3978 uninitialized. Thanks to David Elliot for reporting the bug.
3980 2006-06-01, Version 3.9.3
3981 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
3982 operating systems also profit from the changes, but I wasn't able to
3984 * Changed the build system to find the netinet-includes under FreeBSD
3985 and therefore successfully build the `liboping' library there.
3987 2006-05-09, Version 3.9.2
3988 * Applied a patch to the `liboping' library. Due to a bug in the
3989 sequence checking the `ping' plugin stopped working after
3990 approximately 7.6 days.
3992 2006-05-09, Version 3.8.5
3993 * Applied a patch to the `liboping' library. Due to a bug in the
3994 sequence checking the `ping' plugin stopped working after
3995 approximately 7.6 days.
3997 2006-04-21, Version 3.9.1
3998 * Build issues with Solaris and possible other architectures have been
4000 * Problems when building the `apache'-plugin without `libcurl' have
4002 * A bug in the `ping' plugin has been fixed. Sorry folks.
4004 2006-04-02, Version 3.9.0
4005 * A plugin to monitor the Apache webserver has been added.
4006 <http://httpd.apache.org/>
4007 * A plugin to collect statistics about virtual servers using VServer.
4008 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
4010 * A plugin for wireless LAN cards has been added. It monitors signal
4011 strength, link quality and noise ratio..
4012 * A plugin for Apple hardware sensors has been added.
4013 * An option to compile collectd with different `step' and `heartbeat'
4014 settings has been added. The size of RRAs is no longer static but
4015 calculated based on the settings for `step' and `width'.
4016 * The `ping' plugin can now be configured to use a certain TTL.
4017 * A plugin to monitor the hardware sensors of Apple computers has been
4019 * The plugins `cpu', `memory', `processes' and `traffic' have been
4020 ported to Mach/Darwin (Mac OS X).
4021 * The `log mode' has been contributed by Christophe Kalt. It writes
4022 the data into text files rather than RRD files.
4024 2006-04-09, Version 3.8.4
4025 * Applied patch by Vincent Stehlé which improves the disk-name
4026 resolution in the `hddtemp' plugin for Linux systems.
4028 2006-04-02, Version 3.8.3
4029 * Applied a patch by James Byers: The MySQL plugin was not working
4030 with MySQL 5.0.2 or later.
4032 2006-03-14, Version 3.8.2
4033 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
4034 the GNU libc, because it points to `/etc/fstab' rather than
4037 2006-03-13, Version 3.8.1
4038 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
4039 * Fixes in the debian `postinst' and `init.d' scripts.
4041 2006-03-09, Version 3.8.0
4042 * The `ping' plugin no longer uses `libping' but a self written
4043 library named `liboping'. With this library it's possible to ping
4044 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
4046 2006-02-18, Version 3.7.2
4047 * A simple bug in the `battery' plugin has been fixed. It should now
4048 work with ACPI based batteries as well. Thanks to Sebastian for
4050 * Fixing a bug that prevented collectd to be built without librrd.
4051 Thanks to Werner Heuser for reporting it.
4053 2006-02-04, Version 3.7.1
4054 * The new network code has been improved to build with older versions
4056 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
4057 to Tommie Gannert for this patch.
4059 2006-01-30, Version 3.7.0
4060 * The `battery' plugin has been added. It collects information about
4062 * The MySQL plugin has been improved: It now writes two more RRD
4063 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
4064 * The `cpufreq' plugin now reads another file since the file it did
4065 read so far causes much overhead in the kernel. Also, you need root
4066 to read the old file, but not to read the new one.
4067 * The `hddtemp' plugin can now be configured to connect to another
4068 address and/or port than localhost.
4069 * The `df' plugin now prefers `statvfs' over `statfs'.
4070 * The network code has been rewritten. collectd now supports unicast
4071 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
4072 be set in the configfile.
4074 2006-01-24, Version 3.6.2
4075 * Due to a bug in the configfile handling collectd wouldn't start in
4076 client mode. This released fixes this.
4078 2006-01-20, Version 3.6.1
4079 * Due to a bug in `configure.in' all modules and the binary were
4080 linked against `libmysqlclient'. This issue is solved by this
4083 2006-01-17, Version 3.6.0
4084 * A config file has been added. This allows for loading only specific
4086 * A `df' plugin has been added.
4087 * A `mysql' plugin has been added.
4088 * The `ping' plugin doesn't entirely give up hope when a socket error
4089 occurred, but will back of and increase the intervals between tries.
4091 2006-01-21, Version 3.5.2
4092 * Fixed yet another bug in the signal handling.. Stupid typo..
4093 * Improved the ping plugin to not give up on socket errors (backport
4096 2005-12-18, Version 3.5.1
4097 * The PID-file is now deleted correctly when shutting down the daemon.
4098 * SIGINT and SIGTERM are now handled correctly.
4100 2005-12-16, Version 3.5.0 (Revision 326)
4101 * A bug in the `load' module under Solaris has been fixed.
4102 * The `users' module has been contributed by Sebastian Harl. It counts
4103 currently logged in users.
4104 * The CPU module now works under FreeBSD without the use of
4105 `libstatgrab', however SMP support is missing.
4106 * The default directories for the RRD files and the PID file now
4107 depend on the compile time setting of `localstatedir'.
4109 2005-11-15, Version 3.4.0 (Revision 236)
4110 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
4111 from gentoo's bugzilla for writing the patch.
4112 * The build dependency for librrd has been removed. Binaries built
4113 without librrd are client-only and will multicast their value as
4114 with the `-c' argument.
4115 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
4116 * The newly introduced `-f' switch prevents daemon initialization
4117 (forking, closing standard filehandles, etc.) Thanks to Alvaro
4118 Barcellos for this patch.
4120 2005-11-04, Version 3.3.0 (Revision 216)
4121 * New modules have been added:
4122 - `serial', for monitoring traffic on the serial interfaces
4123 - `nfs', for graphing NFS procedure calls
4124 - `tape', traffic from/to tape devices
4125 * The memory.rrd now accepts more than 4Gig of memory.
4127 2005-10-26, Version 3.2.0 (Revision 200)
4128 * Support for graphing the processes has been added (thanks to Lyonel
4130 * If reading from hddtemp fails collectd will increase the time
4131 between polls up to one day.
4132 * The init.d files have been improved.
4133 * Problems with the spec file have been fixed.
4135 2005-10-16, Version 3.1.0 (Revision 194)
4136 * Added the `setsid' syscall to the startup code.
4137 * Support for hddtemp has been added (thanks to Vincent Stehlé)
4139 2005-09-30, Version 3.0.0 (Revision 184)
4140 * The ability to send/receive data to/from the network (think
4141 multicast) has been added.
4142 * Modules have been split up into shared libraries can be loaded at
4143 runtime. The biggest advantage is that the core program doesn't need
4144 to be linked against an external library.
4145 * A patch by George Kargiotakis has been applied: It fixes the sensors
4146 behaviour then more than one sensor is being queried.
4148 2005-09-16, Version 2.1.0 (Revision 172)
4149 * A module for swap statistics has been added.
4151 2005-09-09, Version 2.0.0 (Revision 135)
4152 * Filenames can no longer be configured at program startup. The only
4153 options as of this version are the directory and ping hosts.
4154 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
4155 Soft-IRQ statistics are added to `System'.
4156 * Diskstats now collect read and write bytes, not sectors.
4157 * Ping statistics can now be collected for more than one host. There
4158 is no default any more: If no host is given no host will be pinged.
4159 * A self-written patch for libping has been applied so it builds
4162 2005-09-01, Version 1.8.1 (Revision 123)
4163 * Much improved configure-script: libraries and features may now be
4165 * More detailed warnings/error messages when RRD update fails.
4167 2005-08-29, Version 1.8.0:
4168 * Support for collecting disk statistics under Solaris.
4170 2005-08-25, Version 1.7.0:
4171 * Support for libstatgrab[1] for load, memory usage and network
4172 traffic. CPU- and disk-usage are not (yet) supported, since
4173 libstatgrab returns insufficient information. I will contact the
4175 * Improved the CPU-initialization code for Solaris. Apparently CPUs
4176 aren't necessarily counted linear which is now handled correctly.
4177 [1]: http://www.i-scream.org/libstatgrab/
4179 2005-08-21, Version 1.6.0:
4180 * Basic support for Solaris: System load and cpu-usage can be
4181 collected under Solaris, too. Other stats will follow later.
4182 * Many fixes in the autoconf-script
4183 * Collection/Museum scripts have been added under contrib/museum
4184 * collectd may now be started in unprivileged mode, though ping
4185 statistics will not work.
4187 2005-07-17, Version 1.5.1:
4188 * Diskstats-RRDs now use major/minor for naming. Some systems have
4189 weird strings as disk-names..
4191 2005-07-17, Version 1.5:
4192 * A new module, diskstats, has been added. It collects information
4193 about the disks and partitions.
4195 2005-07-11, Version 1.4.2:
4196 * The meminfo module has been changed to work with more platforms
4197 and/or kernel versions.
4199 2005-07-10, Version 1.4.1: Correct traffic stats
4200 * The traffic rrd-file is now created with DS-type `COUNTER' which I
4201 forgot to correct when I changed that module.
4203 2005-07-09, Version 1.4: More traffic stats
4204 * Traffic is now collected for all interfaces that can be found
4205 * Temperature-statistics are read from lm-sensors if available
4207 2005-07-08, Version 1.3: CPU stats
4208 * Collecting CPU statistics now
4210 2005-07-12, Version 1.2: Using syslog
4211 * collectd is now using the syslog facility to report errors, warnings
4213 * The default directory is now /var/db/collectd
4215 2005-07-10, Version 1.1: Minor changes
4216 * Nothing really useful to say ;)
4218 2005-07-09, Version 1.0: Initial Version
4219 * The following modules are provided:
