148 code. Thanks to Sebastian Harl for the patch.
149 * collectd: Remove old values when a cache entry is marked as missing.
150 This way the “GETVAL” command of the UnixSock plugin doesn't return

152 Díaz for the patch.
153 * collectd: The “plugin_unregister_read” function has been fixed.
154 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library

160 Thanks to Sebastian Harl for the patch. The build system has been
161 updated to the plugin only includes the shipped header files when it
162 is linked with the shipped library, too.
163 * java plugin: Delay creating the JVM until after the daemon has
164 forked. The JVM internally creates threads that are lost when
165 forking. This means that Java-based plugins are now configured
166 during the init-phase, i. e. later than other plugins.
167 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
168 to Alan Pevec for the patch.

191 details have been added to the configuration summary. Support for
192 libtool 2.2 has been added.
193 * collectd: Two bugs with the threshold checking have been fixed. The
194 first one prevented thresholds to be checked at all, the second one
195 caused wrong behavior with the persistency option. Thanks to Andrés
196 J. Díaz for fixing these problems.
197 * collectd: Handling of the `Include' configuration option has been
198 fixed.
199 * rrdtool plugin: Make sure initialization is run only once. This
200 resolves problems under Solaris and potentially other systems.
201 Thanks to Amit Gupta for reporting this bug.
202 * java plugin: Make it possible to use dots ('.') instead of slashes
203 ('/') as the class separator. Thanks to Randy Rizun for pointing
204 this out.

216 Linux' file-system based caching framework. Thanks to Edward
217 Konetzko for the patch.
218 * gmond plugin: The new gmond plugin can receive and interpret
219 multicast traffic from Ganglia's gmond daemon.
220 * java plugin: The new java plugin exports the collectd API to Java,
221 making it possible to write extensions to collectd in Java.
222 * memcachec plugin: The new memcachec plugin queries data from a
223 memcached daemon and parses it similar to the cURL plugin. Thanks to
224 Doug MacEachern for the initial code.
225 * memcached plugin: Support for connections over UNIX domain sockets
226 has been added. Thanks to Franck Lombardi for the patch.

281 2009-06-02, Version 4.6.3
282 * Build system, various plugins: Many build fixes for FreeBSD,
283 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
284 for many fixes and providing a build system for many platforms,
285 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
286 providing an OpenBSD system.
287 * collectd: Two bugs with the threshold checking have been fixed. The
288 first one prevented thresholds to be checked at all, the second one
289 caused wrong behavior with the persistency option. Thanks to Andrés
290 J. Díaz for fixing these problems.

306 * collectd: Some Solaris utility code has been improved.
307 * filter subsystem: Allow `Chains' without default targets.
308 * liboping: A patch to comply with strict aliasing rules has been
309 added.
310 * timediff match: Fix a typo: The match was registered with a wrong
311 name which prevented this match to be used as documented. Thanks to
312 Bruno Prémont for finding this problem.
313 * bind plugin: Fix collection of the cached RR sets. The number of RR
314 sets currently in the cache was collected as a counter value, which
315 is nonsense. Thanks to Bruno Prémont for implementing this.
316 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
317 primarily BSDs, don't take it well and crash.
318 * oracle plugin: Portability to 64 bit systems has been improved.
319 * postgresql plugin: The default configuration has been improved.
320 * rrdtool plugin: Fix a possible race condition: If the network plugin
321 is brought and dispatches a value before the rrdtool plugin is
322 initialized, the daemon may crash.
324 2009-02-22, Version 4.6.1
325 * collectd: Many documentation fixes.
326 * Collectd::Unixsock: Error handling has been improved.

331 faults. Thanks to Peter Holik for his patch.
333 2009-02-16, Version 4.6.0
334 * collectd: Added the `filter chain' infrastructure, which allows the
335 user to use `matches' and `targets' to control value processing.
336 * collectd: The new `-T' command line argument allows more in-depth
337 testing of a configuration. Thanks to Doug MacEachern for the patch.
338 * collectd-nagios: The Nagios integration command has been updated to
339 use libcollectdclient. The `percentage' aggregation function has
340 been added. Thanks to Fabian Linzberger for the patch.
341 * libcollectdclient: A library which abstracts communication with the
342 unixsock plugin for clients has been added.
343 * regex match: Match values by their identifies using regular
344 expressions.
345 * timediff match: Match for values with an invalid timestamp.
346 * value match: Select values by their data sources' values.
347 * notification target: Create and dispatch a notification.
348 * replace target: Replace parts of an identifier using regular
349 expressions.
350 * set target: Set (overwrite) entire parts of an identifier.
351 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
352 statistics, allowing very detailed name server statistics. Thanks to
353 Bruno Prémont for this plugin.
354 * cpu plugin: Report `interrupt' separately when using
355 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
356 example for native OpenBSD support, has been added. Thanks to Simon
357 Kuhnle for the patch.
358 * csv plugin: Make it possible to write values to STDOUT instead of
359 files. This is meant for testing purposes mostly. The output written
360 to STDOUT is compatible with the exec plugin. Thanks to Doug
361 MacEachern for the patch.
362 * curl plugin: This new plugin can be used to read web pages and parse
363 them using the same mechanism that's used in the tail plugin.
364 * dbi plugin: This new plugin allows you to connect to a variety of
365 relational databases and use SQL to gather custom statistics from
366 it. It is similar to the already existing PostgreSQL plugin but uses
367 libdbi to communicate with the database(s).
368 * interface plugin: Use the ignorelist framework when selecting /
369 ignoring interfaces. This allows one to use regular expressions to
370 select interfaces, too.
371 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
372 Thanks to Bruno Prémont for this patch.
373 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
374 for the patch.

380 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
381 * oracle plugin: This new plugin allows you to connect to an Oracle
382 database and use SQL to gather custom statistics from it. It is
383 similar to the already existing PostgreSQL plugin.
384 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
385 have been added.
386 * perl plugin: Export the newly added plugin_write() to Perl plugins.
387 * perl plugin: Added support for `notification meta data'.
388 * perl plugin: Added support for the `filter chain' infrastructure by
389 allowing plugins to register `matches' and `targets'.
390 * postgresql plugin: The preferred configuration syntax has been
391 updated to be in line with the syntax used by the new dbi and oracle
392 plugins. The compatibility code for the old syntax is present.
393 Support for the new `Result' blocks and the interval parameter has
394 been added.
395 * processes plugin: Stacksize and virtual memory usage statistics have
396 been added. Portability fixes.
397 * rrdcached plugin: This new plugin uses the (still in development)
398 RRD accelerator daemon, rrdcached. This daemon works very similar to
399 the original rrdtool plugin of collectd, but adds some more nice
400 features.
401 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
402 added.
404 2009-05-09, Version 4.5.4
405 * Build system, various plugins: Many build fixes for FreeBSD,
406 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
407 for many fixes and providing a build system for many platforms,
408 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
409 providing an OpenBSD system.
410 * collectd: Fix a potential race condition when creating directories.
411 * battery plugin: Don't complain about a missing directory every
412 interval.
413 * dns plugin: Slight portability fixes.
414 * exec plugin: Allow executed programs to close STDERR. Thanks to
415 Thorsten von Eicken for reporting this problem.
416 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
417 Tomasz Pala for the patch.
418 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
419 the patch.
420 * rrdtool plugin: Fix a possible race condition: If the network plugin
421 is initialized and dispatches a value before the rrdtool plugin is
422 initialized, the daemon may crash.
423 * memory plugin: Fix a potential problem under Solaris.
425 2009-02-22, Version 4.5.3
426 * build system: The check for libupsclient even when `pkg-config' is
427 not available.
428 * collectd: Fix error handling in the global cache.
429 * Collectd::Unixsock: Error handling has been improved.
430 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
431 patch.
432 * ipmi plugin: Fix an off-by-one error which could cause segmentation
433 faults. Thanks to Peter Holik for his patch.
434 * tcpconns plugin: An endianness problem has been fixed in the *BSD
435 code. Thanks to "thated" for reporting this.
437 2009-01-02, Version 4.5.2
438 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
439 file may be in both locations, especially when the database was
440 installed in a non-standard path. Thanks to Dusty Doris for
441 reporting this.
442 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
443 Solaris, in the configure script automatically.
444 * build system, tcpconns plugin: Check for `kvm_nlist' and
445 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
446 library with similar functions to the BSD variant, but doesn't
447 provide these necessary functions.
448 * collectd.conf(5): Various fixes and clarifications.
449 * collectd: Remove a GNUism (unnamed unions), thus improving
450 portability.
451 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
452 This solves portability problems, especially for Solaris.
453 * dns plugin: Fix a portability problem with NetBSD.
454 * filecount plugin: Fix an off-by-one error. This error may cause a
455 segmentation fault.
456 * network plugin: Fix the handling of `type' in the network protocol.
457 Due to a programming mistake, only 4 or 8 bytes would be copied to a
458 much larger buffer. This caused the `type' to be transferred much
459 more often than necessary. In some cases, e. g. the `cpu' and
460 `cpufreq' plugins being used at the same time, data may be corrupted
461 in those files. Thanks to Bruno Prémont for debugging and reporting
462 this issue.
463 * processes plugin: Fix a possible segmentation fault when specifying
464 invalid configuration options.
465 * unixsock plugin: Make sure the initialization function is run only
466 once. This resolves a file descriptor leak under systems which run
467 the initialization more than once, such as Solaris.
469 2008-10-16, Version 4.5.1
470 * build system: Change `--enable-<plugin>' to abort with an error if
471 dependencies are not met. Thanks to Bruno Prémont for the patch.
472 Also, the poisoning of various string functions has been restricted
473 to debug builds.
474 * collectd: Fix a memory leak in the global value cache. With every
475 *missing* value a couple of bytes would be leaked. Another memory
476 leak in the configuration handling code has been fixed. Thanks to
477 Niraj Tolia for reporting these issues.
478 * collectd: Fix an off-by-one error in the ignorelist functionality.
479 When using regular expressions, the last character would be missing,
480 possibly matching differently from what one would expect.
481 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
482 problem.
483 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
484 Linzberger for reporting the bug.
485 * iptables plugin: Fix an off-by-one error. If a string was just one
486 character too long, it was truncated instead of reporting an error.
487 * network plugin: Fix a memory leak in the configuration handling
488 code. Thanks to Niraj Tolia for reporting this issue.
489 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
490 * postgresql plugin: Don't reopen connection during reinitialization.
491 This fixes a bug under Solaris and potentially other platforms.
492 Missing calls to `PQclear' have been added, too. This fixes memory
493 leaks. Thanks to ``Admin'' for reporting these bugs.
494 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
495 library.
496 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
497 problems with some `libc's. Thanks to Matthias Lay for reporting the
498 bug.
500 2008-09-04, Version 4.5.0
501 * collectd: Added the ability to flush certain identifiers.
502 * collectd: The concept of `notification meta data' has been
503 introduced.
504 * filecount plugin: The new filecount plugin counts the number of
505 files in a directory and its subdirectories.
506 * ipmi plugin: Sensor names have been changed to ensure unique names.
507 Notifications upon added and removed sensors can now be generated.
508 * notify_desktop plugin: This new plugin sends notifications to the
509 X desktop using the structure defined in the `Desktop Notification
510 Specification'.
511 * notify_email plugin: This new plugin sends out notifications via
512 email, using the `esmtp' library.
513 * onewire plugin: The new experimental(!) onewire plugin reads values,
514 such as temperatures, from sensors connected to the computer via the
515 onewire bus.
516 * perl plugin: Improved synchronized access to internal data structures
517 and fixed a possible dead-lock.
518 * perl plugin: Added the ability to flush certain identifiers and marked
519 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
520 plugin_flush().
521 * perl plugin: Added the ability to configure Perl plugins.
522 * postgresql plugin: The new postgresql plugin collects statistics
523 about or from a PostgreSQL database.
524 * processes plugin: The `ProcessMatch' option has been added.
525 * rrdtool plugin: Implement throttling of the `update queue' to lessen
526 IO load.
527 * tcpconns plugin: This plugin has been ported to OpenBSD.
528 * thermal plugin: The new thermal plugin collects system temperatures
529 using Linux ACPI thermal zone data.
531 2009-01-02, Version 4.4.5
532 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
533 file may be in both locations, especially when the database was
534 installed in a non-standard path. Thanks to Dusty Doris for
535 reporting this.
536 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
537 Solaris, in the configure script automatically.
538 * collectd.conf(5): Various fixes and clarifications.
539 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
540 portability problems, especially for Solaris.
541 * dns plugin: Fix a portability problem with NetBSD.
542 * network plugin: Fix the handling of `type' in the network protocol.
543 Due to a programming mistake, only 4 or 8 bytes would be copied to a
544 much larger buffer. This caused the `type' to be transferred much
545 more often than necessary. In some cases, e. g. the `cpu' and
546 `cpufreq' plugins being used at the same time, data may be corrupted
547 in those files. Thanks to Bruno Prémont for debugging and reporting
548 this issue.
549 * unixsock plugin: Make sure the initialization function is run only
550 once. This resolves a file descriptor leak under systems which run
551 the initialization more than once, such as Solaris.
553 2008-10-16, Version 4.4.4
554 * build system: Change `--enable-<plugin>' to abort with an error if
555 dependencies are not met. Thanks to Bruno Prémont for the patch.
556 Also, the poisoning of various string functions has been restricted
557 to debug builds.
558 * collectd: Fix a memory leak in the global value cache. With every
559 *missing* value a couple of bytes would be leaked. Another memory
560 leak in the configuration handling code has been fixed. Thanks to
561 Niraj Tolia for reporting these issues.
562 * collectd: Fix an off-by-one error in the ignorelist functionality.
563 When using regular expressions, the last character would be missing,
564 possibly matching differently from what one would expect.
565 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
566 problem.
567 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
568 Linzberger for reporting the bug.
569 * network plugin: Fix a memory leak in the configuration handling
570 code. Thanks to Niraj Tolia for reporting this issue.
571 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
572 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
573 problems with some `libc's. Thanks to Matthias Lay for reporting the
574 bug.
576 2008-09-01, Version 4.4.3
577 * collectd: Fix a memory leak in the threshold checking code.
578 * memcached plugin: Fix a too short timeout and a related file
579 descriptor leak.
580 * memory plugin: A typo in the libstatgrab code has been fixed.
581 * snmp plugin: Fix a possible memory leak.
583 2008-07-15, Version 4.4.2
584 * build system: Use pkg-config to detect the upsclient library.
585 * collectd: Try even harder to determine the endianess of the
586 architecture collectd is being built on.
587 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
588 of disks.
589 * dns plugin: Fix compilation errors with BIND versions 19991001
590 through 19991005.
591 * network plugin: Bugfix in the init routine: The init function
592 cleared a buffer regardless of its contents. This could lead to lost
593 values under Solaris.
594 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
595 * vserver plugin: Remove usage of the thread-unsafe `readdir'
596 function.
597 * wireless plugin: Work around incorrect noise and power values
598 returned by some broken drivers.
600 2008-06-03, Version 4.4.1
601 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
602 to kyrone for reporting this.
603 * collectd: Fixed min/max output in notifications generated by
604 threshold checking.
605 * collectd-nagios: Fix the protocol used to communicate with the
606 daemon.
607 * perl plugin: Fail noisily, but don't shutdown the daemon, if
608 initialization has errors. An issue with Perl 5.10 has been fixed.
609 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
610 René Rebe and Siegmund Gorr for reporting this.
612 2008-05-06, Version 4.4.0
613 * collectd: Internal code cleanups.
614 * collectd: Added support for a `Flush' command in the unixsock and
615 exec plugins. This command can be used to force a plugin (or all) to
616 flush its values to disk.
617 * collectd: Thresholds can now be configured to apply to one data
618 source only, making it possible to configure different thresholds
619 for each data source.
620 * apache, nginx plugins: Added the possibility to disable host and/or
621 peer verification.
622 * ascent plugin: The new ascent plugin reads and parses the statistics
623 page of an Ascent server.
624 * cpu plugin: Support for the statgrab library has been added.
625 * disk plugin: The possibility to ignore certain disks or collect only
626 specific disks has been added.
627 * disk plugin: Support for the statgrab library has been added.
628 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
629 sensor values via IPMI, the intelligent platform management
630 interface.
631 * iptables plugin: The iptc library that is used by the iptables
632 plugin has been added to the distribution, because it is not
633 provided by all distributions and removed from at least one.
634 * powerdns plugin: The new powerdns plugin reads statistics from an
635 authoritative or a recursing PowerDNS name server.
636 * rrdtool plugin: The size of the files generated with the default
637 configuration has been decreased.
638 * tail plugin: The new tail plugin can be used to gather statistics by
639 continuously reading from log files.
640 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
641 TeamSpeak2 server and collects statistics about the number of users
642 and number of channels.
643 * users plugin: Support for the statgrab library has been added.
644 * vmem plugin: The new vmem plugin collects very detailed statistics
645 about the virtual memory subsystem of Linux.
647 2008-08-30, Version 4.3.4
648 * Build system: Improved detection of and linking with the statgrab
649 library.
650 * collectd: Portability fixes, especially to determine endianess more
651 reliable.
652 * Various plugins: Fix format strings.
653 * disk plugin: A fix for giving disks under Linux 2.4 the right names
654 again has been applied.
655 * memcached plugin: Fix a too short timeout and a related file
656 descriptor leak.
657 * memory plugin: A typo in the libstatgrab code has been fixed.
658 * network plugin: A fix in the initialization function solves problems
659 under Solaris.

661 * vserver plugin: A thread-unsafe function has been replaced.
662 * wireless plugin: A work-around for broken wireless drivers has been
663 added.
665 2008-04-22, Version 4.3.3
666 * build system: Improved detection of several libraries, especially if
667 they are in non-standard paths.
668 * build system: Portability fixes: Automatically define "_REENTRANT"
669 if the libc expects it.
670 * collectd: Error and warning messages have been improved.
671 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
672 using them.
673 * apache plugin: Allocate new memory when reading a webpage instead of
674 using a buffer of static size.
675 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
676 the program.
677 * hddtemp plugin: Error and warning messages have been improved.
678 * sensors plugin: Fix sensor collection for some chip types.
680 2008-03-29, Version 4.3.2
681 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
682 `Persist' threshold options.
683 * collectd: Fix handling of missing values in the global value cache.
684 * collectd: Improved error messages when parsing the configuration.
685 * sensors plugin: Fix temperature collection with libsensors4.
686 * unixsock plugin: Fix mixed input and output operation on streams.
687 * wireless plugin: Fix reading noise value.
689 2008-03-05, Version 4.3.1
690 * exec plugin: Set supplementary group IDs.
691 * network plugin:
692 + Use `memcpy' when constructing/parsing a package to avoid
693 alignment problems on weird architectures, such as Sparc.
694 + Translate doubles to/from the x86 byte representation to ensure
695 cross-platform compatibility.
696 * ping plugin: Correct the handling of the `TTL' setting.
697 * swap plugin: Reapply a patch for Solaris.
698 * tcpconns plugin: Portability improvements.
700 2008-02-18, Version 4.3.0
701 * collectd: Notifications have been added to the daemon. Notifications
702 are status messages that may be associated with a data instance.
703 * collectd: Threshold checking has been added to the daemon. This
704 means that you can configure threshold values for each data
705 instance. If this threshold is exceeded a notification will be
706 created.
707 * collectd: The new `FQDNLookup' option tells the daemon to use the
708 full qualified domain name as the hostname, not just the host part
709 es returned by `gethostname(2)'.
710 * collectd: Support for more than one `TypesDB' file has been added.
711 This is useful when one such file is included in a package but one
712 wants to add custom type definitions.
713 * collectd: The `Include' config option has been expanded to handle
714 entire directories and shell wildcards.
715 * collectdmon: The new `collectdmon' binary detects when collectd
716 terminates and automatically restarts it again.
717 * csv plugin: The CSV plugin is now able to store counter values as a
718 rate, using the `StoreRates' configuration option.
719 * exec plugin: Handling of notifications has been added and the
720 ability to pass arguments to the executed programs has been added.
721 * hddtemp plugin: The new `TranslateDevicename' option lets you
722 disable the translation from device names to major-minor-numbers.
723 * logfile plugin: Handling of notifications has been added.
724 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
725 domain name lookups in this plugin.
726 * perl plugin: Many internal changes added support for handling multiple
727 threads making the plugin reasonably usable inside collectd. The API has
728 been extended to support notifications and export global variables to
729 Perl plugins; callbacks now have to be identified by name rather than a
730 pointer to a subroutine. The plugin is no longer experimental.
731 * uuid plugin: The new UUID plugin sets the hostname to an unique
732 identifier for this host. This is meant for setups where each client
733 may migrate to another physical host, possibly going through one or
734 more name changes in the process. Thanks to Richard Jones from
735 Red Hat's Emerging Technology group for this plugin.
736 * libvirt: The new libvirt plugin uses the `libvirt' library to query
737 CPU, disk and network statistics about guest systems on the same
738 physical server. Thanks to Richard Jones from Red Hat's Emerging
739 Technology group for this plugin.
741 2008-04-22, Version 4.2.7
742 * build system: Improved detection of several libraries, especially if
743 they are in non-standard paths.
744 * build system: Portability fixes: Automatically define "_REENTRANT"
745 if the libc expects it.
746 * collectd: Error and warning messages have been improved.
747 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
748 using them.
749 * apache plugin: Allocate new memory when reading a webpage instead of
750 using a buffer of static size.
751 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
752 the program.
753 * hddtemp plugin: Error and warning messages have been improved.
754 * sensors plugin: Fix sensor collection for some chip types.
756 2008-03-29, Version 4.2.6
757 * collectd: Improved error messages when parsing the configuration.
758 * sensors plugin: Fix temperature collection with libsensors4.
759 * unixsock plugin: Fix mixed input and output operation on streams.
760 * wireless plugin: Fix reading noise value.
762 2008-03-04, Version 4.2.5
763 * apache plugin: Improved initialization and error messages.
764 * exec plugin: Set supplementary group IDs.
765 * network plugin:
766 + Create separate threads for reading from the socket and parsing
767 and dispatching incoming packets. Versions prior to this may have
768 problems in high-load situations, where the socket receive buffers
769 overflows, resulting in gaps in the data.
770 + Use `memcpy' when constructing/parsing a package to avoid
771 alignment problems on weird architectures, such as Sparc.
772 + Translate doubles to/from the x86 byte representation to ensure
773 cross-platform compatibility.
774 * ping plugin: Correct the handling of the `TTL' setting.
775 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
776 * swap plugin: Reapply a patch for Solaris.
777 * tcpconns plugin: Portability improvements.
779 2008-01-21, Version 4.2.4
780 * unixsock plugin: A bug in the unixsock plugin caused it not to set
781 the permission on the socket as documented in the manpage. Thanks to
782 Evgeny Chukreev for fixing this issue.
783 * collectd: The documentation has been improved.
785 2007-12-28, Version 4.2.3
786 * sensors plugin: Updated the plugin to build and work with version 3
787 of the libsensors library.
789 2007-12-15, Version 4.2.2
790 * nginx plugin: Incorrect comparison of strings lead to a segfault
791 when using the plugin. Thanks to Saulius Grigaliunas for fixing
792 this.
793 * logfile plugin: The config option `Timestamp' was handled
794 incorrectly and basically always active. Thanks to Luke Heberling
795 for fixing this.
797 2007-11-08, Version 4.2.1
798 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
799 enabled on the host.
800 * snmp plugin: Fix a memory leak.
802 2007-10-27, Version 4.2.0
803 * collectd: The new config option `Include' lets you include other
804 configfiles and thus split up your config into smaller parts. This
805 may be especially interesting for the snmp plugin to keep the data
806 definitions separate from the host definitions.
807 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
808 (number of connections, octets and packets for each service and
809 destination). Thanks to Sebastian Harl for this plugin.
810 * memcached plugin: The new `memcached' plugin connects to a memcached
811 daemon process and collects statistics of this distributed caching
812 system. Thanks to Antony Dovgal for contributing this plugin.
813 * nginx plugin: The new `nginx' plugin reads the status page of an
814 nginx daemon and saves the handled connections and requests.
815 * perl plugin: Many changes, including the added `EnableDebugger'
816 config option which lets you debug your Perl plugins more easily.
817 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
818 be more thread-safe otherwise by locking calls to the library.
819 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
820 correct the values returned by SNMP-agents. If a <data> block is
821 defined as `table' the instance is now optional. The sequence number
822 is used as the type-instance in this case. The new `InstancePrefix'
823 option allows to add arbitrary prefixes to the type-instance.
824 * tcpconns plugin: The new `tcpconns' plugin collects the number of
825 certain TCP connections and what state they're in. This can be used
826 to see how many connections your FTP server has to handle or how
827 many outgoing connections your mailserver has open.
829 2008-01-11, Version 4.1.6
830 * unixsock plugin: A bug in the unixsock plugin caused it not to set
831 the permission on the socket as documented in the manpage. Thanks to
832 Evgeny Chukreev for fixing this issue.
833 * collectd: The documentation has been improved.
835 2007-12-27, Version 4.1.5
836 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
837 memory situations.

839 of the libsensors library.
841 2007-11-08, Version 4.1.4
842 * Build system: Improve detection of the rrd library, especially if
843 it's in a non-standard location.
844 * Build system: A bug when parsing the argument for
845 `--with-libnetsnmp' has been fixed.
846 * collectd: Implement `strerror_r' if the libc doesn't provide it.
847 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
848 a deadlock or delay when shutting down the daemon.
849 * snmp plugin: Fix a memory leak.
851 2007-10-24, Version 4.1.3
852 * collectd: A build issue under Solaris has been resolved by renaming
853 data types.
854 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
855 be more thread-safe otherwise by locking calls to the library.
857 2007-09-28, Version 4.1.2
858 * apcups plugin: Fix reporting of the `load percent' data.
859 * wireless plugin: Correct the handling of cards returning signal and
860 noise quality as percentage.
861 * perl plugin: Fix a possible buffer overflow in get_module_name().
862 * build system: Further improve the detection of libraries.
863 * netlink plugin: Build issues under some older versions of the Linux
864 includes (i. e. Debian Sarge) have been fixed.
865 * snmp plugin: Fix a potential segfault when a host times out. Add
866 support for the `timeticks' type.
868 2007-09-12, Version 4.1.1
869 * Build system: The detection of `libnetlink' has been improved.
870 * collectd: The documentation has been fixed in numerous places.
871 * exec plugin: Setting the group under which to run a program has been
872 fixed.
873 * collectd: The `sstrerror' function was improved to work correctly
874 with the broken GNU version of `strerror_r'.
875 * collectd: Write an error message to STDERR when loading of a plugin
876 fails.
877 * apcups plugin: Fix the `types' used to submit the values: They still
878 has an `apcups_' prefix which doesn't work anymore.
879 * rrdtool plugin: Create new RRD-files with the `begin' time set to
880 whatever the client thinks is `now'..
882 2007-09-01, Version 4.1.0
883 * Build system: The build system has been changed to automatically
884 disable all plugins, which are missing dependencies. The dependency
885 checking has been removed from the plugins themselves to remove
886 redundancy.
887 * Flexible interval: The interval of collected data is now sent along
888 with the data itself over the network, so that the interval-settings
889 of server and clients no longer needs to match.
890 * netlink plugin: The new `netlink' plugin connects to the Linux
891 kernel using a netlink socket and uses it to query information about
892 interfaces, qdiscs and classes.
893 * rrdtool plugin: The cache is now dumped to disk in an extra thread
894 to not block data collection.
895 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
896 network devices, such as switches, routers, thermometers, rack
897 monitoring servers, etc. The collectd-snmp(5) manpage documents this
898 plugin.
899 * unixsock plugin: Added the `LISTVAL' command.
900 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
901 of music played with xmms.
903 2007-09-28, Version 4.0.9
904 * apcups plugin: Fix reporting of the `load percent' data.
905 * wireless plugin: Correct the handling of cards returning signal and
906 noise quality as percentage.
907 * perl plugin: Fix a possible buffer overflow in get_module_name().
909 2007-09-12, Version 4.0.8
910 * collectd: The `sstrerror' function was improved to work correctly
911 with the broken GNU version of `strerror_r'.
912 * collectd: Write an error message to STDERR when loading of a plugin
913 fails.
914 * apcups plugin: Fix the `types' used to submit the values: They still
915 has an `apcups_' prefix which doesn't work anymore.
916 * rrdtool plugin: Create new RRD-files with the `begin' time set to
917 whatever the client thinks is `now'..
919 2007-08-26, Version 4.0.7
920 * documentation: Some typos have been fixed and some information has
921 been improved.
922 * build system: Many fixes for detecting libraries in unusual places,
923 such as on RedHat systems. The affected libraries are `libcurl',
924 `libmysql', and `libupsclient'.
925 * network plugin: Allow the `Port' option to be specified as a number
926 (i. e. without quotes).
927 * nut plugin: A fix allows linking the nut plugin against
928 libupsclient, version >= 2.2.0.
929 * processes plugin: Fix a potential segmentation fault.
931 2007-07-30, Version 4.0.6
932 * sensors plugin: Fix the ignorelist functionality: Only the `type
933 instance' was used to match against the list, but the documentation
934 told otherwise. This release fixes the code, so it complies with the
935 documentation.
936 * syslog plugin: Call `openlog' right when the plugin is loaded, so
937 configuration messages will end up in the logging facility.
938 * conrtib/fedora: The contributed specfile for Fedora has been
939 updated.
941 2007-07-05, Version 4.0.5
942 * Portability: More fixes for OpenBSD have been included.
944 2007-06-24, Version 4.0.4
945 * cpu plugin: Fixed the Solaris code.
946 * dns plugin: Fixed a build issue for OpenBSD.
947 * interface plugin: Fixed the Solaris code.
948 * load plugin: Fixed the alternative `/proc' Linux code.
949 * memory plugin: Fixed the Solaris code.
950 * oconfig: Don't require `-lfl' anymore.
952 2007-06-19, Version 4.0.3
953 * cpu plugin: Fix the Darwin / Mac OS X code.
954 * ping plugin: Use the return value of `getpid', not its address.
955 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
956 initialized correctly.
957 * configure: Added `--with-nan-emulation' to aid cross compilation.
959 2007-06-12, Version 4.0.2
960 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
961 they're given in numerically form.
963 2007-06-07, Version 4.0.1
964 * iptables plugin: A bug in the configuration routine has been fixed.
965 Setting a comment in the configfile will no longer cause a
966 segmentation fault.
968 2007-06-03, Version 4.0.0
969 * collectd: The plugin-infrastructure has been changed to allow for
970 more types of plugins, namely `write' and `log' plugins.
971 * collectd: The read-function has been changed to read many plugins in
972 parallel, using threads. Thus, plugins generally need to use
973 thread-safe functions from now on.
974 * collectd: The '-t' command line options allows to perform syntax tests
975 of the configuration file and exit immediately.
976 * csv plugin: The new `csv' plugin handles output to `comma separated
977 values'-files.
978 * rrdtool plugin: The new `rrdtool' plugin handles output to
979 RRD-files. Data can be cached to combine multiple updates into one
980 write to increase IO-performance.
981 * network plugin: The new `network' plugin handles IO via the network.
982 It implements a different, much more extensible protocol which can
983 combine many values in one packet, decreasing the number of UDP-
984 packets being sent. It can read from and send to the network and
985 with the appropriate configuration even forward packets to other
986 networks.
987 * unixsock plugin: The new `unixsock' plugin provides an interface to
988 communicate with the daemon while it is running. Right now the
989 commands `GETVAL' and `PUTVAL' are implemented, but more are to
990 come.
991 * perl plugin: The new `perl' plugin allows you to write extensions
992 for collectd in the scripting-language Perl.
993 * logfile plugin: The new `logfile' plugin writes logmessages to files
994 or STDOUT or STDERR.
995 * syslog plugin: The new `syslog' plugin sends logmessages to the
996 system's syslog daemon.
997 * entropy plugin: The new `entropy' plugin collects the amount of
998 entropy currently being available to the system.
999 * exec plugin: The new `exec' plugin forks child processes and reads
1000 back values provided by the forked processes.
1001 * iptables plugin: The new `iptables' plugin reads counters from
1002 iptables rules. Thanks to Sjoerd van der Berg for contributing this
1003 plugin.
1004 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
1005 to Peter Holik for contributing this plugin.
1006 * nut plugin: The new `nut' plugin connects the upsd of the `network
1007 ups tools' and reads information about the connected UPS.
1008 * apache plugin: Support for lighttpd's `BusyServers' (aka.
1009 connections) field was added by Florent Monbillard.
1010 * collectd-nagios: The new `collectd-nagios' binary queries values
1011 from collectd, parses them and exits according to Nagios-standards.
1012 * manpages: The manpages have been improved a lot.
1014 2007-09-28, Version 3.11.7
1015 * wireless plugin: Correct the handling of cards returning signal and
1016 noise quality as percentage.
1018 2007-08-31, Version 3.11.6
1019 * processes plugin: Fix a potential segmentation fault.
1021 2007-05-29, Version 3.11.5
1022 * configure: Added `AC_SYS_LARGEFILE' for LFS.
1023 * ntpd plugin: Fix a potential buffer overflow.
1024 * processes plugin: Fix a bug when run under Linux 2.4. All processes
1025 were accounted as `zombies'.
1027 2007-04-10, Version 3.11.4
1028 * dns plugin: Change the order of includes to make the plugin compile
1029 under FreeBSD.
1031 2007-03-30, Version 3.11.3
1032 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
1033 of the unused `COLLECT_KSTAT'.
1035 2007-02-11, Version 3.11.2
1036 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
1037 NULL-pointer may have been passed to `printf' which causes a
1038 segfault with some libcs.
1040 2007-02-10, Version 3.11.1
1041 * df plugin: Some wrong defines have been fixed so the plugin works
1042 under Solaris again.
1043 * dns plugin: The usage of a struct has been fixed to work with
1044 non-GNU libcs.
1045 * processes plugin: Some missing defines have been added so the plugin
1046 compiles cleanly under FreeBSD and presumably other UNIXes.
1048 2006-12-22, Version 3.11.0
1049 * collectd: The new command line option `-P' makes it easier for
1050 distributors to change the location of PID-files.
1051 * collectd: The daemon shuts down faster now which makes it easier to
1052 write init.d-scripts for it.
1053 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
1054 caused problems every now and then.
1055 * df plugin: New config options allow to ignore certain mountpoints,
1056 filesystem types or devices.
1057 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
1058 and interprets it. It collects traffic as well as qtype, opcode and
1059 rcode counts.
1060 * email plugin: Sebastian Harl has contributed this plugin which
1061 counts received mails in categories (e. g. ham, spam, virus), spam
1062 score (as given by SpamAssassin) and check types.
1063 * mbmon plugin: Flavio Stanchina has contributed this plugin which
1064 uses `mbmon' to gather information from sensors on the motherboard.
1065 * processes plugin: Collect detailed statistics for configured
1066 processes, that's process and thread count, CPU usage, resident
1067 segment size and pagefaults.
1068 * multimeter plugin: Peter Holik contributed a new plugin which
1069 queries multimeters.
1070 * sensors plugin: Lubos Stanek has put much effort into improving this
1071 plugin, including `extended naming', collection of voltage values
1072 and the possibility to ignore certain values.
1074 2006-12-21, Version 3.10.4
1075 * Max Kellermann has identified a bug in the server routine: When
1076 opening a socket fails the daemon will (re)try opening the socket in
1077 an endless loop, ultimately leading to a `EMFILE' error.
1079 2006-11-04, Version 3.10.3
1080 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
1081 ntpd's reply was sent in more than one packet, the buffer size was
1082 calculated incorrectly, resulting in the reading of uninitialized or
1083 freed memory.
1085 2006-11-01, Version 3.10.2
1086 * The sample config file has been improved.
1087 * Errors in the manpages have been corrected.
1088 * The ping-plugin now adds hosts during initialization, not during
1089 startup. This speeds up startup when no network connectivity is
1090 available. Also, the hosts are being added later when the network is
1091 available.
1092 * Improved BSD-support for the df-plugin.
1093 * Fixed syntax errors in the swap-plugin for Mac OS X.
1094 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
1095 plugin.
1096 * Don't disable the mysql-plugin if connecting to the database fails
1097 during initialization. Instead, try again in increasing intervals.
1099 2006-07-19, Version 3.10.1
1100 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
1101 the apcups cannot be reached, unconnected sockets will pile up and
1102 eventually lead to `Too many open files' errors.
1104 2006-07-09, Version 3.10.0
1105 * The `disk' plugin has been ported to Darwin.
1106 * The `battery' plugin should work on many Apple computers now.
1107 * The `traffic' plugin can now ignore certain interfaces. Also,
1108 statistics for sent/received packets and errors have been added.
1109 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
1110 to Anthony Gialluca for contributing this plugin and providing me
1111 with a test environment :)
1112 * A plugin for monitoring an NTP instance and the local clock drift
1113 has been added.
1115 2006-06-25, Version 3.9.4
1116 * The Solaris code in the `swap' plugin has been changed to reflect
1117 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1118 working this out.
1119 * The debugging system has been fixed to work with the Sun libc.
1120 * When built without librrd the variable `operating_mode' could be
1121 uninitialized. Thanks to David Elliot for reporting the bug.
1123 2006-06-01, Version 3.9.3
1124 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1125 operating systems also profit from the changes, but I wasn't able to
1126 check that.
1127 * Changed the build system to find the netinet-includes under FreeBSD
1128 and therefore successfully build the `liboping' library there.
1130 2006-05-09, Version 3.9.2
1131 * Applied a patch to the `liboping' library. Due to a bug in the
1132 sequence checking the `ping' plugin stopped working after
1133 approximately 7.6 days.
1135 2006-05-09, Version 3.8.5
1136 * Applied a patch to the `liboping' library. Due to a bug in the
1137 sequence checking the `ping' plugin stopped working after
1138 approximately 7.6 days.
1140 2006-04-21, Version 3.9.1
1141 * Build issues with Solaris and possible other architectures have been
1142 resolved.
1143 * Problems when building the `apache'-plugin without `libcurl' have
1144 been resolved.
1145 * A bug in the `ping' plugin has been fixed. Sorry folks.
1147 2006-04-02, Version 3.9.0
1148 * A plugin to monitor the Apache webserver has been added.
1149 <http://httpd.apache.org/>
1150 * A plugin to collect statistics about virtual servers using VServer.
1151 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1152 this plugin :)
1153 * A plugin for wireless LAN cards has been added. It monitors signal
1154 strength, link quality and noise ratio..
1155 * A plugin for Apple hardware sensors has been added.
1156 * An option to compile collectd with different `step' and `heartbeat'
1157 settings has been added. The size of RRAs is no longer static but
1158 calculated based on the settings for `step' and `width'.
1159 * The `ping' plugin can now be configured to use a certain TTL.
1160 * A plugin to monitor the hardware sensors of Apple computers has been
1161 added.
1162 * The plugins `cpu', `memory', `processes' and `traffic' have been
1163 ported to Mach/Darwin (Mac OS X).
1164 * The `log mode' has been contributed by Christophe Kalt. It writes
1165 the data into text files rather than RRD files.
1167 2006-04-09, Version 3.8.4
1168 * Applied patch by Vincent Stehlé which improves the disk-name
1169 resolution in the `hddtemp' plugin for Linux systems.
1171 2006-04-02, Version 3.8.3
1172 * Applied a patch by James Byers: The MySQL plugin was not working
1173 with MySQL 5.0.2 or later.
1175 2006-03-14, Version 3.8.2
1176 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1177 the GNU libc, because it points to `/etc/fstab' rather than
1178 `/etc/mtab'.
1180 2006-03-13, Version 3.8.1
1181 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1182 * Fixes in the debian `postinst' and `init.d' scripts.
1184 2006-03-09, Version 3.8.0
1185 * The `ping' plugin no longer uses `libping' but a self written
1186 library named `liboping'. With this library it's possible to ping
1187 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1189 2006-02-18, Version 3.7.2
1190 * A simple bug in the `battery' plugin has been fixed. It should now
1191 work with ACPI based batteries as well. Thanks to Sebastian for
1192 fixing this.
1193 * Fixing a bug that prevented collectd to be built without librrd.
1194 Thanks to Werner Heuser for reporting it.
1196 2006-02-04, Version 3.7.1
1197 * The new network code has been improved to build with older versions
1198 of glibc.
1199 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1200 to Tommie Gannert for this patch.
1202 2006-01-30, Version 3.7.0
1203 * The `battery' plugin has been added. It collects information about
1204 laptop batteries..
1205 * The MySQL plugin has been improved: It now writes two more RRD
1206 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1207 * The `cpufreq' plugin now reads another file since the file it did
1208 read so far causes much overhead in the kernel. Also, you need root
1209 to read the old file, but not to read the new one.
1210 * The `hddtemp' plugin can now be configured to connect to another
1211 address and/or port than localhost.
1212 * The `df' plugin now prefers `statvfs' over `statfs'.
1213 * The network code has been rewritten. collectd now supports unicast
1214 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1215 be set in the configfile.
1217 2006-01-24, Version 3.6.2
1218 * Due to a bug in the configfile handling collectd wouldn't start in
1219 client mode. This released fixes this.
1221 2006-01-20, Version 3.6.1
1222 * Due to a bug in `configure.in' all modules and the binary were
1223 linked against `libmysqlclient'. This issue is solved by this
1224 release.
1226 2006-01-17, Version 3.6.0
1227 * A config file has been added. This allows for loading only specific
1228 plugins.
1229 * A `df' plugin has been added.
1230 * A `mysql' plugin has been added.
1231 * The `ping' plugin doesn't entirely give up hope when a socket error
1232 occurred, but will back of and increase the intervals between tries.
1234 2006-01-21, Version 3.5.2
1235 * Fixed yet another bug in the signal handling.. Stupid typo..
1236 * Improved the ping plugin to not give up on socket errors (backport
1237 from 3.6.0).
1239 2005-12-18, Version 3.5.1
1240 * The PID-file is now deleted correctly when shutting down the daemon.
1241 * SIGINT and SIGTERM are now handled correctly.
1243 2005-12-16, Version 3.5.0 (Revision 326)
1244 * A bug in the `load' module under Solaris has been fixed.
1245 * The `users' module has been contributed by Sebastian Harl. It counts
1246 currently logged in users.
1247 * The CPU module now works under FreeBSD without the use of
1248 `libstatgrab', however SMP support is missing.
1249 * The default directories for the RRD files and the PID file now
1250 depend on the compile time setting of `localstatedir'.
1252 2005-11-15, Version 3.4.0 (Revision 236)
1253 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1254 from gentoo's bugzilla for writing the patch.
1255 * The build dependency for librrd has been removed. Binaries built
1256 without librrd are client-only and will multicast their value as
1257 with the `-c' argument.
1258 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1259 * The newly introduced `-f' switch prevents daemon initialization
1260 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1261 Barcellos for this patch.
1263 2005-11-04, Version 3.3.0 (Revision 216)
1264 * New modules have been added:
1265 - `serial', for monitoring traffic on the serial interfaces
1266 - `nfs', for graphing NFS procedure calls
1267 - `tape', traffic from/to tape devices
1268 * The memory.rrd now accepts more than 4Gig of memory.
1270 2005-10-26, Version 3.2.0 (Revision 200)
1271 * Support for graphing the processes has been added (thanks to Lyonel
1272 Vincent)
1273 * If reading from hddtemp fails collectd will increase the time
1274 between polls up to one day.
1275 * The init.d files have been improved.
1276 * Problems with the spec file have been fixed.
1278 2005-10-16, Version 3.1.0 (Revision 194)
1279 * Added the `setsid' syscall to the startup code.
1280 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1282 2005-09-30, Version 3.0.0 (Revision 184)
1283 * The ability to send/receive data to/from the network (think
1284 multicast) has been added.
1285 * Modules have been split up into shared libraries can be loaded at
1286 runtime. The biggest advantage is that the core program doesn't need
1287 to be linked against an external library.
1288 * A patch by George Kargiotakis has been applied: It fixes the sensors
1289 behaviour then more than one sensor is being queried.
1291 2005-09-16, Version 2.1.0 (Revision 172)
1292 * A module for swap statistics has been added.
1294 2005-09-09, Version 2.0.0 (Revision 135)
1295 * Filenames can no longer be configured at program startup. The only
1296 options as of this version are the directory and ping hosts.
1297 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1298 Soft-IRQ statistics are added to `System'.
1299 * Diskstats now collect read and write bytes, not sectors.
1300 * Ping statistics can now be collected for more than one host. There
1301 is no default any more: If no host is given no host will be pinged.
1302 * A self-written patch for libping has been applied so it builds
1303 cleanly.
1305 2005-09-01, Version 1.8.1 (Revision 123)
1306 * Much improved configure-script: libraries and features may now be
1307 disabled.
1308 * More detailed warnings/error messages when RRD update fails.
1310 2005-08-29, Version 1.8.0:
1311 * Support for collecting disk statistics under Solaris.
1313 2005-08-25, Version 1.7.0:
1314 * Support for libstatgrab[1] for load, memory usage and network
1315 traffic. CPU- and disk-usage are not (yet) supported, since
1316 libstatgrab returns insufficient information. I will contact the
1317 authors.
1318 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1319 aren't necessarily counted linear which is now handled correctly.
1320 [1]: http://www.i-scream.org/libstatgrab/
1322 2005-08-21, Version 1.6.0:
1323 * Basic support for Solaris: System load and cpu-usage can be
1324 collected under Solaris, too. Other stats will follow later.
1325 * Many fixes in the autoconf-script
1326 * Collection/Museum scripts have been added under contrib/museum
1327 * collectd may now be started in unprivileged mode, though ping
1328 statistics will not work.
1330 2005-07-17, Version 1.5.1:
1331 * Diskstats-RRDs now use major/minor for naming. Some systems have
1332 weird strings as disk-names..
1334 2005-07-17, Version 1.5:
1335 * A new module, diskstats, has been added. It collects information
1336 about the disks and partitions.
1338 2005-07-11, Version 1.4.2:
1339 * The meminfo module has been changed to work with more platforms
1340 and/or kernel versions.
1342 2005-07-10, Version 1.4.1: Correct traffic stats
1343 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1344 forgot to correct when I changed that module.
1346 2005-07-09, Version 1.4: More traffic stats
1347 * Traffic is now collected for all interfaces that can be found
1348 * Temperature-statistics are read from lm-sensors if available
1350 2005-07-08, Version 1.3: CPU stats
1351 * Collecting CPU statistics now
1353 2005-07-12, Version 1.2: Using syslog
1354 * collectd is now using the syslog facility to report errors, warnings
1355 and the like..
1356 * The default directory is now /var/db/collectd
1358 2005-07-10, Version 1.1: Minor changes
1359 * Nothing really useful to say ;)
1361 2005-07-09, Version 1.0: Initial Version
1362 * The following modules are provided:
1363 * Load average
1364 * Ping time
1365 * Traffic
1366 * Memory info
