45 2009-06-02, Version 4.6.3
46 * Build system, various plugins: Many build fixes for FreeBSD,
47 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
48 for many fixes and providing a build system for many platforms,
49 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
50 providing an OpenBSD system.
51 * collectd: Two bugs with the threshold checking have been fixed. The
52 first one prevented thresholds to be checked at all, the second one
53 caused wrong behavior with the persistency option. Thanks to Andrés
54 J. Díaz for fixing these problems.
55 * collectd: Handling of the `Include' configuration option has been
56 fixed.
57 * battery plugin: Don't complain about a missing directory every
58 interval.

71 * filter subsystem: Allow `Chains' without default targets.
72 * liboping: A patch to comply with strict aliasing rules has been
73 added.
74 * timediff match: Fix a typo: The match was registered with a wrong
75 name which prevented this match to be used as documented. Thanks to
76 Bruno Prémont for finding this problem.
77 * bind plugin: Fix collection of the cached RR sets. The number of RR
78 sets currently in the cache was collected as a counter value, which
79 is nonsense. Thanks to Bruno Prémont for implementing this.
80 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
81 primarily BSDs, don't take it well and crash.
82 * oracle plugin: Portability to 64 bit systems has been improved.
83 * postgresql plugin: The default configuration has been improved.
84 * rrdtool plugin: Fix a possible race condition: If the network plugin
85 is brought and dispatches a value before the rrdtool plugin is
86 initialized, the daemon may crash.
88 2009-02-22, Version 4.6.1
89 * collectd: Many documentation fixes.
90 * Collectd::Unixsock: Error handling has been improved.
91 * regex match: Don't link with the PCRE library.

95 faults. Thanks to Peter Holik for his patch.
97 2009-02-16, Version 4.6.0
98 * collectd: Added the `filter chain' infrastructure, which allows the
99 user to use `matches' and `targets' to control value processing.
100 * collectd: The new `-T' command line argument allows more in-depth
101 testing of a configuration. Thanks to Doug MacEachern for the patch.
102 * collectd-nagios: The Nagios integration command has been updated to
103 use libcollectdclient. The `percentage' aggregation function has
104 been added. Thanks to Fabian Linzberger for the patch.
105 * libcollectdclient: A library which abstracts communication with the
106 unixsock plugin for clients has been added.
107 * regex match: Match values by their identifies using regular
108 expressions.
109 * timediff match: Match for values with an invalid timestamp.
110 * value match: Select values by their data sources' values.
111 * notification target: Create and dispatch a notification.
112 * replace target: Replace parts of an identifier using regular
113 expressions.
114 * set target: Set (overwrite) entire parts of an identifier.
115 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
116 statistics, allowing very detailed name server statistics. Thanks to
117 Bruno Prémont for this plugin.
118 * cpu plugin: Report `interrupt' separately when using
119 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
120 example for native OpenBSD support, has been added. Thanks to Simon
121 Kuhnle for the patch.
122 * csv plugin: Make it possible to write values to STDOUT instead of
123 files. This is meant for testing purposes mostly. The output written
124 to STDOUT is compatible with the exec plugin. Thanks to Doug
125 MacEachern for the patch.
126 * curl plugin: This new plugin can be used to read web pages and parse
127 them using the same mechanism that's used in the tail plugin.
128 * dbi plugin: This new plugin allows you to connect to a variety of
129 relational databases and use SQL to gather custom statistics from
130 it. It is similar to the already existing PostgreSQL plugin but uses
131 libdbi to communicate with the database(s).
132 * interface plugin: Use the ignorelist framework when selecting /
133 ignoring interfaces. This allows one to use regular expressions to
134 select interfaces, too.
135 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
136 Thanks to Bruno Prémont for this patch.
137 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern

149 have been added.
150 * perl plugin: Export the newly added plugin_write() to Perl plugins.
151 * perl plugin: Added support for `notification meta data'.
152 * perl plugin: Added support for the `filter chain' infrastructure by
153 allowing plugins to register `matches' and `targets'.
154 * postgresql plugin: The preferred configuration syntax has been
155 updated to be in line with the syntax used by the new dbi and oracle
156 plugins. The compatibility code for the old syntax is present.
157 Support for the new `Result' blocks and the interval parameter has
158 been added.
159 * processes plugin: Stacksize and virtual memory usage statistics have
160 been added. Portability fixes.
161 * rrdcached plugin: This new plugin uses the (still in development)
162 RRD accelerator daemon, rrdcached. This daemon works very similar to
163 the original rrdtool plugin of collectd, but adds some more nice
164 features.
165 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
166 added.
168 2009-05-09, Version 4.5.4
169 * Build system, various plugins: Many build fixes for FreeBSD,
170 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
171 for many fixes and providing a build system for many platforms,
172 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
173 providing an OpenBSD system.
174 * collectd: Fix a potential race condition when creating directories.
175 * battery plugin: Don't complain about a missing directory every

181 Tomasz Pala for the patch.
182 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
183 the patch.
184 * rrdtool plugin: Fix a possible race condition: If the network plugin
185 is initialized and dispatches a value before the rrdtool plugin is
186 initialized, the daemon may crash.
187 * memory plugin: Fix a potential problem under Solaris.
189 2009-02-22, Version 4.5.3
190 * build system: The check for libupsclient even when `pkg-config' is
191 not available.
192 * collectd: Fix error handling in the global cache.
193 * Collectd::Unixsock: Error handling has been improved.
194 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

197 faults. Thanks to Peter Holik for his patch.
198 * tcpconns plugin: An endianness problem has been fixed in the *BSD
199 code. Thanks to "thated" for reporting this.
201 2009-01-02, Version 4.5.2
202 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
203 file may be in both locations, especially when the database was
204 installed in a non-standard path. Thanks to Dusty Doris for
205 reporting this.
206 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
207 Solaris, in the configure script automatically.
208 * build system, tcpconns plugin: Check for `kvm_nlist' and
209 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
210 library with similar functions to the BSD variant, but doesn't
211 provide these necessary functions.
212 * collectd.conf(5): Various fixes and clarifications.
213 * collectd: Remove a GNUism (unnamed unions), thus improving
214 portability.
215 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
216 This solves portability problems, especially for Solaris.
217 * dns plugin: Fix a portability problem with NetBSD.
218 * filecount plugin: Fix an off-by-one error. This error may cause a
219 segmentation fault.
220 * network plugin: Fix the handling of `type' in the network protocol.
221 Due to a programming mistake, only 4 or 8 bytes would be copied to a
222 much larger buffer. This caused the `type' to be transferred much
223 more often than necessary. In some cases, e. g. the `cpu' and
224 `cpufreq' plugins being used at the same time, data may be corrupted
225 in those files. Thanks to Bruno Prémont for debugging and reporting
226 this issue.
227 * processes plugin: Fix a possible segmentation fault when specifying
228 invalid configuration options.
229 * unixsock plugin: Make sure the initialization function is run only
230 once. This resolves a file descriptor leak under systems which run
231 the initialization more than once, such as Solaris.
233 2008-10-16, Version 4.5.1
234 * build system: Change `--enable-<plugin>' to abort with an error if
235 dependencies are not met. Thanks to Bruno Prémont for the patch.
236 Also, the poisoning of various string functions has been restricted
237 to debug builds.
238 * collectd: Fix a memory leak in the global value cache. With every
239 *missing* value a couple of bytes would be leaked. Another memory
240 leak in the configuration handling code has been fixed. Thanks to
241 Niraj Tolia for reporting these issues.
242 * collectd: Fix an off-by-one error in the ignorelist functionality.
243 When using regular expressions, the last character would be missing,
244 possibly matching differently from what one would expect.
245 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
246 problem.
247 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
248 Linzberger for reporting the bug.
249 * iptables plugin: Fix an off-by-one error. If a string was just one
250 character too long, it was truncated instead of reporting an error.
251 * network plugin: Fix a memory leak in the configuration handling
252 code. Thanks to Niraj Tolia for reporting this issue.
253 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
254 * postgresql plugin: Don't reopen connection during reinitialization.
255 This fixes a bug under Solaris and potentially other platforms.
256 Missing calls to `PQclear' have been added, too. This fixes memory
257 leaks. Thanks to ``Admin'' for reporting these bugs.
258 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
259 library.
260 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
261 problems with some `libc's. Thanks to Matthias Lay for reporting the
262 bug.
264 2008-09-04, Version 4.5.0
265 * collectd: Added the ability to flush certain identifiers.
266 * collectd: The concept of `notification meta data' has been
267 introduced.
268 * filecount plugin: The new filecount plugin counts the number of
269 files in a directory and its subdirectories.
270 * ipmi plugin: Sensor names have been changed to ensure unique names.
271 Notifications upon added and removed sensors can now be generated.
272 * notify_desktop plugin: This new plugin sends notifications to the
273 X desktop using the structure defined in the `Desktop Notification
274 Specification'.
275 * notify_email plugin: This new plugin sends out notifications via
276 email, using the `esmtp' library.
277 * onewire plugin: The new experimental(!) onewire plugin reads values,
278 such as temperatures, from sensors connected to the computer via the
279 onewire bus.
280 * perl plugin: Improved synchronized access to internal data structures
281 and fixed a possible dead-lock.
282 * perl plugin: Added the ability to flush certain identifiers and marked
283 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
284 plugin_flush().
285 * perl plugin: Added the ability to configure Perl plugins.
286 * postgresql plugin: The new postgresql plugin collects statistics
287 about or from a PostgreSQL database.
288 * processes plugin: The `ProcessMatch' option has been added.
289 * rrdtool plugin: Implement throttling of the `update queue' to lessen
290 IO load.
291 * tcpconns plugin: This plugin has been ported to OpenBSD.
292 * thermal plugin: The new thermal plugin collects system temperatures
293 using Linux ACPI thermal zone data.
295 2009-01-02, Version 4.4.5
296 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
297 file may be in both locations, especially when the database was
298 installed in a non-standard path. Thanks to Dusty Doris for
299 reporting this.
300 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
301 Solaris, in the configure script automatically.
302 * collectd.conf(5): Various fixes and clarifications.
303 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
304 portability problems, especially for Solaris.
305 * dns plugin: Fix a portability problem with NetBSD.
306 * network plugin: Fix the handling of `type' in the network protocol.
307 Due to a programming mistake, only 4 or 8 bytes would be copied to a
308 much larger buffer. This caused the `type' to be transferred much
309 more often than necessary. In some cases, e. g. the `cpu' and
310 `cpufreq' plugins being used at the same time, data may be corrupted
311 in those files. Thanks to Bruno Prémont for debugging and reporting
312 this issue.
313 * unixsock plugin: Make sure the initialization function is run only
314 once. This resolves a file descriptor leak under systems which run
315 the initialization more than once, such as Solaris.
317 2008-10-16, Version 4.4.4
318 * build system: Change `--enable-<plugin>' to abort with an error if
319 dependencies are not met. Thanks to Bruno Prémont for the patch.
320 Also, the poisoning of various string functions has been restricted
321 to debug builds.
322 * collectd: Fix a memory leak in the global value cache. With every
323 *missing* value a couple of bytes would be leaked. Another memory
324 leak in the configuration handling code has been fixed. Thanks to
325 Niraj Tolia for reporting these issues.
326 * collectd: Fix an off-by-one error in the ignorelist functionality.
327 When using regular expressions, the last character would be missing,

352 of disks.
353 * dns plugin: Fix compilation errors with BIND versions 19991001
354 through 19991005.
355 * network plugin: Bugfix in the init routine: The init function
356 cleared a buffer regardless of its contents. This could lead to lost
357 values under Solaris.
358 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
359 * vserver plugin: Remove usage of the thread-unsafe `readdir'
360 function.

372 initialization has errors. An issue with Perl 5.10 has been fixed.
373 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
374 René Rebe and Siegmund Gorr for reporting this.
376 2008-05-06, Version 4.4.0
377 * collectd: Internal code cleanups.
378 * collectd: Added support for a `Flush' command in the unixsock and
379 exec plugins. This command can be used to force a plugin (or all) to
380 flush its values to disk.
381 * collectd: Thresholds can now be configured to apply to one data
382 source only, making it possible to configure different thresholds
383 for each data source.
384 * apache, nginx plugins: Added the possibility to disable host and/or
385 peer verification.
386 * ascent plugin: The new ascent plugin reads and parses the statistics
387 page of an Ascent server.

393 sensor values via IPMI, the intelligent platform management
394 interface.
395 * iptables plugin: The iptc library that is used by the iptables
396 plugin has been added to the distribution, because it is not
397 provided by all distributions and removed from at least one.

460 * ping plugin: Correct the handling of the `TTL' setting.
461 * swap plugin: Reapply a patch for Solaris.
462 * tcpconns plugin: Portability improvements.
464 2008-02-18, Version 4.3.0
465 * collectd: Notifications have been added to the daemon. Notifications
466 are status messages that may be associated with a data instance.
467 * collectd: Threshold checking has been added to the daemon. This
468 means that you can configure threshold values for each data
469 instance. If this threshold is exceeded a notification will be
470 created.
471 * collectd: The new `FQDNLookup' option tells the daemon to use the
472 full qualified domain name as the hostname, not just the host part
473 es returned by `gethostname(2)'.
474 * collectd: Support for more than one `TypesDB' file has been added.
475 This is useful when one such file is included in a package but one
476 wants to add custom type definitions.
477 * collectd: The `Include' config option has been expanded to handle
478 entire directories and shell wildcards.
479 * collectdmon: The new `collectdmon' binary detects when collectd
480 terminates and automatically restarts it again.
481 * csv plugin: The CSV plugin is now able to store counter values as a
482 rate, using the `StoreRates' configuration option.
483 * exec plugin: Handling of notifications has been added and the
484 ability to pass arguments to the executed programs has been added.
485 * hddtemp plugin: The new `TranslateDevicename' option lets you
486 disable the translation from device names to major-minor-numbers.
487 * logfile plugin: Handling of notifications has been added.
488 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
489 domain name lookups in this plugin.
490 * perl plugin: Many internal changes added support for handling multiple
491 threads making the plugin reasonably usable inside collectd. The API has
492 been extended to support notifications and export global variables to
493 Perl plugins; callbacks now have to be identified by name rather than a
494 pointer to a subroutine. The plugin is no longer experimental.
495 * uuid plugin: The new UUID plugin sets the hostname to an unique
496 identifier for this host. This is meant for setups where each client
497 may migrate to another physical host, possibly going through one or
498 more name changes in the process. Thanks to Richard Jones from
499 Red Hat's Emerging Technology group for this plugin.
500 * libvirt: The new libvirt plugin uses the `libvirt' library to query
501 CPU, disk and network statistics about guest systems on the same
502 physical server. Thanks to Richard Jones from Red Hat's Emerging
503 Technology group for this plugin.
505 2008-04-22, Version 4.2.7
506 * build system: Improved detection of several libraries, especially if
507 they are in non-standard paths.
508 * build system: Portability fixes: Automatically define "_REENTRANT"
509 if the libc expects it.
510 * collectd: Error and warning messages have been improved.
511 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
512 using them.
513 * apache plugin: Allocate new memory when reading a webpage instead of
514 using a buffer of static size.
515 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
516 the program.
517 * hddtemp plugin: Error and warning messages have been improved.
518 * sensors plugin: Fix sensor collection for some chip types.
520 2008-03-29, Version 4.2.6
521 * collectd: Improved error messages when parsing the configuration.
522 * sensors plugin: Fix temperature collection with libsensors4.
523 * unixsock plugin: Fix mixed input and output operation on streams.
524 * wireless plugin: Fix reading noise value.
526 2008-03-04, Version 4.2.5
527 * apache plugin: Improved initialization and error messages.
528 * exec plugin: Set supplementary group IDs.
529 * network plugin:
530 + Create separate threads for reading from the socket and parsing
531 and dispatching incoming packets. Versions prior to this may have
532 problems in high-load situations, where the socket receive buffers
533 overflows, resulting in gaps in the data.
534 + Use `memcpy' when constructing/parsing a package to avoid
535 alignment problems on weird architectures, such as Sparc.
536 + Translate doubles to/from the x86 byte representation to ensure
537 cross-platform compatibility.
538 * ping plugin: Correct the handling of the `TTL' setting.
539 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
540 * swap plugin: Reapply a patch for Solaris.
541 * tcpconns plugin: Portability improvements.
543 2008-01-21, Version 4.2.4
544 * unixsock plugin: A bug in the unixsock plugin caused it not to set
545 the permission on the socket as documented in the manpage. Thanks to
546 Evgeny Chukreev for fixing this issue.
547 * collectd: The documentation has been improved.
549 2007-12-28, Version 4.2.3
550 * sensors plugin: Updated the plugin to build and work with version 3
551 of the libsensors library.
553 2007-12-15, Version 4.2.2
554 * nginx plugin: Incorrect comparison of strings lead to a segfault
555 when using the plugin. Thanks to Saulius Grigaliunas for fixing
556 this.
557 * logfile plugin: The config option `Timestamp' was handled
558 incorrectly and basically always active. Thanks to Luke Heberling
559 for fixing this.
561 2007-11-08, Version 4.2.1
562 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
563 enabled on the host.
564 * snmp plugin: Fix a memory leak.
566 2007-10-27, Version 4.2.0
567 * collectd: The new config option `Include' lets you include other
568 configfiles and thus split up your config into smaller parts. This
569 may be especially interesting for the snmp plugin to keep the data
570 definitions separate from the host definitions.
571 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
572 (number of connections, octets and packets for each service and
573 destination). Thanks to Sebastian Harl for this plugin.
574 * memcached plugin: The new `memcached' plugin connects to a memcached
575 daemon process and collects statistics of this distributed caching
576 system. Thanks to Antony Dovgal for contributing this plugin.
577 * nginx plugin: The new `nginx' plugin reads the status page of an
578 nginx daemon and saves the handled connections and requests.
579 * perl plugin: Many changes, including the added `EnableDebugger'
580 config option which lets you debug your Perl plugins more easily.
581 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
582 be more thread-safe otherwise by locking calls to the library.
583 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
584 correct the values returned by SNMP-agents. If a <data> block is
585 defined as `table' the instance is now optional. The sequence number
586 is used as the type-instance in this case. The new `InstancePrefix'
587 option allows to add arbitrary prefixes to the type-instance.
588 * tcpconns plugin: The new `tcpconns' plugin collects the number of
589 certain TCP connections and what state they're in. This can be used
590 to see how many connections your FTP server has to handle or how
591 many outgoing connections your mailserver has open.
593 2008-01-11, Version 4.1.6
594 * unixsock plugin: A bug in the unixsock plugin caused it not to set
595 the permission on the socket as documented in the manpage. Thanks to
596 Evgeny Chukreev for fixing this issue.
597 * collectd: The documentation has been improved.
599 2007-12-27, Version 4.1.5
600 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
601 memory situations.
602 * sensors plugin: Updated the plugin to build and work with version 3
603 of the libsensors library.
605 2007-11-08, Version 4.1.4
606 * Build system: Improve detection of the rrd library, especially if
607 it's in a non-standard location.
608 * Build system: A bug when parsing the argument for
609 `--with-libnetsnmp' has been fixed.
610 * collectd: Implement `strerror_r' if the libc doesn't provide it.
611 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
612 a deadlock or delay when shutting down the daemon.
613 * snmp plugin: Fix a memory leak.
615 2007-10-24, Version 4.1.3
616 * collectd: A build issue under Solaris has been resolved by renaming
617 data types.
618 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
619 be more thread-safe otherwise by locking calls to the library.
621 2007-09-28, Version 4.1.2
622 * apcups plugin: Fix reporting of the `load percent' data.
623 * wireless plugin: Correct the handling of cards returning signal and
624 noise quality as percentage.
625 * perl plugin: Fix a possible buffer overflow in get_module_name().
626 * build system: Further improve the detection of libraries.
627 * netlink plugin: Build issues under some older versions of the Linux
628 includes (i. e. Debian Sarge) have been fixed.
629 * snmp plugin: Fix a potential segfault when a host times out. Add
630 support for the `timeticks' type.
632 2007-09-12, Version 4.1.1
633 * Build system: The detection of `libnetlink' has been improved.
634 * collectd: The documentation has been fixed in numerous places.
635 * exec plugin: Setting the group under which to run a program has been
636 fixed.
637 * collectd: The `sstrerror' function was improved to work correctly
638 with the broken GNU version of `strerror_r'.
639 * collectd: Write an error message to STDERR when loading of a plugin
640 fails.
641 * apcups plugin: Fix the `types' used to submit the values: They still
642 has an `apcups_' prefix which doesn't work anymore.
643 * rrdtool plugin: Create new RRD-files with the `begin' time set to
644 whatever the client thinks is `now'..
646 2007-09-01, Version 4.1.0
647 * Build system: The build system has been changed to automatically
648 disable all plugins, which are missing dependencies. The dependency
649 checking has been removed from the plugins themselves to remove
650 redundancy.
651 * Flexible interval: The interval of collected data is now sent along
652 with the data itself over the network, so that the interval-settings
653 of server and clients no longer needs to match.
654 * netlink plugin: The new `netlink' plugin connects to the Linux
655 kernel using a netlink socket and uses it to query information about
656 interfaces, qdiscs and classes.
657 * rrdtool plugin: The cache is now dumped to disk in an extra thread
658 to not block data collection.
659 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
660 network devices, such as switches, routers, thermometers, rack
661 monitoring servers, etc. The collectd-snmp(5) manpage documents this
662 plugin.
663 * unixsock plugin: Added the `LISTVAL' command.
664 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
665 of music played with xmms.
667 2007-09-28, Version 4.0.9
668 * apcups plugin: Fix reporting of the `load percent' data.
669 * wireless plugin: Correct the handling of cards returning signal and
670 noise quality as percentage.
671 * perl plugin: Fix a possible buffer overflow in get_module_name().
673 2007-09-12, Version 4.0.8
674 * collectd: The `sstrerror' function was improved to work correctly
675 with the broken GNU version of `strerror_r'.
676 * collectd: Write an error message to STDERR when loading of a plugin
677 fails.
678 * apcups plugin: Fix the `types' used to submit the values: They still
679 has an `apcups_' prefix which doesn't work anymore.
680 * rrdtool plugin: Create new RRD-files with the `begin' time set to
681 whatever the client thinks is `now'..
683 2007-08-26, Version 4.0.7
684 * documentation: Some typos have been fixed and some information has
685 been improved.
686 * build system: Many fixes for detecting libraries in unusual places,
687 such as on RedHat systems. The affected libraries are `libcurl',
688 `libmysql', and `libupsclient'.
689 * network plugin: Allow the `Port' option to be specified as a number
690 (i. e. without quotes).
691 * nut plugin: A fix allows linking the nut plugin against
692 libupsclient, version >= 2.2.0.
693 * processes plugin: Fix a potential segmentation fault.
695 2007-07-30, Version 4.0.6
696 * sensors plugin: Fix the ignorelist functionality: Only the `type
697 instance' was used to match against the list, but the documentation
698 told otherwise. This release fixes the code, so it complies with the
699 documentation.
700 * syslog plugin: Call `openlog' right when the plugin is loaded, so
701 configuration messages will end up in the logging facility.
702 * conrtib/fedora: The contributed specfile for Fedora has been
703 updated.
705 2007-07-05, Version 4.0.5
706 * Portability: More fixes for OpenBSD have been included.
708 2007-06-24, Version 4.0.4
709 * cpu plugin: Fixed the Solaris code.
710 * dns plugin: Fixed a build issue for OpenBSD.
711 * interface plugin: Fixed the Solaris code.
712 * load plugin: Fixed the alternative `/proc' Linux code.
713 * memory plugin: Fixed the Solaris code.
714 * oconfig: Don't require `-lfl' anymore.
716 2007-06-19, Version 4.0.3
717 * cpu plugin: Fix the Darwin / Mac OS X code.
718 * ping plugin: Use the return value of `getpid', not its address.
719 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
720 initialized correctly.
721 * configure: Added `--with-nan-emulation' to aid cross compilation.
723 2007-06-12, Version 4.0.2
724 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
725 they're given in numerically form.
727 2007-06-07, Version 4.0.1
728 * iptables plugin: A bug in the configuration routine has been fixed.
729 Setting a comment in the configfile will no longer cause a
730 segmentation fault.
732 2007-06-03, Version 4.0.0
733 * collectd: The plugin-infrastructure has been changed to allow for
734 more types of plugins, namely `write' and `log' plugins.
735 * collectd: The read-function has been changed to read many plugins in
736 parallel, using threads. Thus, plugins generally need to use
737 thread-safe functions from now on.
738 * collectd: The '-t' command line options allows to perform syntax tests
739 of the configuration file and exit immediately.
740 * csv plugin: The new `csv' plugin handles output to `comma separated
741 values'-files.
742 * rrdtool plugin: The new `rrdtool' plugin handles output to
743 RRD-files. Data can be cached to combine multiple updates into one
744 write to increase IO-performance.
745 * network plugin: The new `network' plugin handles IO via the network.
746 It implements a different, much more extensible protocol which can
747 combine many values in one packet, decreasing the number of UDP-
748 packets being sent. It can read from and send to the network and
749 with the appropriate configuration even forward packets to other
750 networks.
751 * unixsock plugin: The new `unixsock' plugin provides an interface to
752 communicate with the daemon while it is running. Right now the
753 commands `GETVAL' and `PUTVAL' are implemented, but more are to
754 come.
755 * perl plugin: The new `perl' plugin allows you to write extensions
756 for collectd in the scripting-language Perl.
757 * logfile plugin: The new `logfile' plugin writes logmessages to files
758 or STDOUT or STDERR.
759 * syslog plugin: The new `syslog' plugin sends logmessages to the
760 system's syslog daemon.
761 * entropy plugin: The new `entropy' plugin collects the amount of
762 entropy currently being available to the system.
763 * exec plugin: The new `exec' plugin forks child processes and reads
764 back values provided by the forked processes.
765 * iptables plugin: The new `iptables' plugin reads counters from
766 iptables rules. Thanks to Sjoerd van der Berg for contributing this
767 plugin.
768 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
769 to Peter Holik for contributing this plugin.
770 * nut plugin: The new `nut' plugin connects the upsd of the `network
771 ups tools' and reads information about the connected UPS.
772 * apache plugin: Support for lighttpd's `BusyServers' (aka.
773 connections) field was added by Florent Monbillard.
774 * collectd-nagios: The new `collectd-nagios' binary queries values
775 from collectd, parses them and exits according to Nagios-standards.
776 * manpages: The manpages have been improved a lot.
778 2007-09-28, Version 3.11.7
779 * wireless plugin: Correct the handling of cards returning signal and
780 noise quality as percentage.
782 2007-08-31, Version 3.11.6
783 * processes plugin: Fix a potential segmentation fault.
785 2007-05-29, Version 3.11.5
786 * configure: Added `AC_SYS_LARGEFILE' for LFS.
787 * ntpd plugin: Fix a potential buffer overflow.
788 * processes plugin: Fix a bug when run under Linux 2.4. All processes
789 were accounted as `zombies'.
791 2007-04-10, Version 3.11.4
792 * dns plugin: Change the order of includes to make the plugin compile
793 under FreeBSD.
795 2007-03-30, Version 3.11.3
796 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
797 of the unused `COLLECT_KSTAT'.
799 2007-02-11, Version 3.11.2
800 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
801 NULL-pointer may have been passed to `printf' which causes a
802 segfault with some libcs.
804 2007-02-10, Version 3.11.1
805 * df plugin: Some wrong defines have been fixed so the plugin works
806 under Solaris again.
807 * dns plugin: The usage of a struct has been fixed to work with
808 non-GNU libcs.
809 * processes plugin: Some missing defines have been added so the plugin
810 compiles cleanly under FreeBSD and presumably other UNIXes.
812 2006-12-22, Version 3.11.0
813 * collectd: The new command line option `-P' makes it easier for
814 distributors to change the location of PID-files.
815 * collectd: The daemon shuts down faster now which makes it easier to
816 write init.d-scripts for it.
817 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
818 caused problems every now and then.
819 * df plugin: New config options allow to ignore certain mountpoints,
820 filesystem types or devices.
821 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
822 and interprets it. It collects traffic as well as qtype, opcode and
823 rcode counts.
824 * email plugin: Sebastian Harl has contributed this plugin which
825 counts received mails in categories (e. g. ham, spam, virus), spam
826 score (as given by SpamAssassin) and check types.
827 * mbmon plugin: Flavio Stanchina has contributed this plugin which
828 uses `mbmon' to gather information from sensors on the motherboard.
829 * processes plugin: Collect detailed statistics for configured
830 processes, that's process and thread count, CPU usage, resident
831 segment size and pagefaults.
832 * multimeter plugin: Peter Holik contributed a new plugin which
833 queries multimeters.
834 * sensors plugin: Lubos Stanek has put much effort into improving this
835 plugin, including `extended naming', collection of voltage values
836 and the possibility to ignore certain values.
838 2006-12-21, Version 3.10.4
839 * Max Kellermann has identified a bug in the server routine: When
840 opening a socket fails the daemon will (re)try opening the socket in
841 an endless loop, ultimately leading to a `EMFILE' error.
843 2006-11-04, Version 3.10.3
844 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
845 ntpd's reply was sent in more than one packet, the buffer size was
846 calculated incorrectly, resulting in the reading of uninitialized or
847 freed memory.
849 2006-11-01, Version 3.10.2
850 * The sample config file has been improved.
851 * Errors in the manpages have been corrected.
852 * The ping-plugin now adds hosts during initialization, not during
853 startup. This speeds up startup when no network connectivity is
854 available. Also, the hosts are being added later when the network is
855 available.
856 * Improved BSD-support for the df-plugin.
857 * Fixed syntax errors in the swap-plugin for Mac OS X.
858 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
859 plugin.
860 * Don't disable the mysql-plugin if connecting to the database fails
861 during initialization. Instead, try again in increasing intervals.
863 2006-07-19, Version 3.10.1
864 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
865 the apcups cannot be reached, unconnected sockets will pile up and
866 eventually lead to `Too many open files' errors.
868 2006-07-09, Version 3.10.0
869 * The `disk' plugin has been ported to Darwin.
870 * The `battery' plugin should work on many Apple computers now.
871 * The `traffic' plugin can now ignore certain interfaces. Also,
872 statistics for sent/received packets and errors have been added.
873 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
874 to Anthony Gialluca for contributing this plugin and providing me
875 with a test environment :)
876 * A plugin for monitoring an NTP instance and the local clock drift
877 has been added.
879 2006-06-25, Version 3.9.4
880 * The Solaris code in the `swap' plugin has been changed to reflect
881 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
882 working this out.
883 * The debugging system has been fixed to work with the Sun libc.
884 * When built without librrd the variable `operating_mode' could be
885 uninitialized. Thanks to David Elliot for reporting the bug.
887 2006-06-01, Version 3.9.3
888 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
889 operating systems also profit from the changes, but I wasn't able to
890 check that.
891 * Changed the build system to find the netinet-includes under FreeBSD
892 and therefore successfully build the `liboping' library there.
894 2006-05-09, Version 3.9.2
895 * Applied a patch to the `liboping' library. Due to a bug in the
896 sequence checking the `ping' plugin stopped working after
897 approximately 7.6 days.
899 2006-05-09, Version 3.8.5
900 * Applied a patch to the `liboping' library. Due to a bug in the
901 sequence checking the `ping' plugin stopped working after
902 approximately 7.6 days.
904 2006-04-21, Version 3.9.1
905 * Build issues with Solaris and possible other architectures have been
906 resolved.
907 * Problems when building the `apache'-plugin without `libcurl' have
908 been resolved.
909 * A bug in the `ping' plugin has been fixed. Sorry folks.
911 2006-04-02, Version 3.9.0
912 * A plugin to monitor the Apache webserver has been added.
913 <http://httpd.apache.org/>
914 * A plugin to collect statistics about virtual servers using VServer.
915 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
916 this plugin :)
917 * A plugin for wireless LAN cards has been added. It monitors signal
918 strength, link quality and noise ratio..
919 * A plugin for Apple hardware sensors has been added.
920 * An option to compile collectd with different `step' and `heartbeat'
921 settings has been added. The size of RRAs is no longer static but
922 calculated based on the settings for `step' and `width'.
923 * The `ping' plugin can now be configured to use a certain TTL.
924 * A plugin to monitor the hardware sensors of Apple computers has been
925 added.
926 * The plugins `cpu', `memory', `processes' and `traffic' have been
927 ported to Mach/Darwin (Mac OS X).
928 * The `log mode' has been contributed by Christophe Kalt. It writes
929 the data into text files rather than RRD files.
931 2006-04-09, Version 3.8.4
932 * Applied patch by Vincent Stehlé which improves the disk-name
933 resolution in the `hddtemp' plugin for Linux systems.
935 2006-04-02, Version 3.8.3
936 * Applied a patch by James Byers: The MySQL plugin was not working
937 with MySQL 5.0.2 or later.
939 2006-03-14, Version 3.8.2
940 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
941 the GNU libc, because it points to `/etc/fstab' rather than
942 `/etc/mtab'.
944 2006-03-13, Version 3.8.1
945 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
946 * Fixes in the debian `postinst' and `init.d' scripts.
948 2006-03-09, Version 3.8.0
949 * The `ping' plugin no longer uses `libping' but a self written
950 library named `liboping'. With this library it's possible to ping
951 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
953 2006-02-18, Version 3.7.2
954 * A simple bug in the `battery' plugin has been fixed. It should now
955 work with ACPI based batteries as well. Thanks to Sebastian for
956 fixing this.
957 * Fixing a bug that prevented collectd to be built without librrd.
958 Thanks to Werner Heuser for reporting it.
960 2006-02-04, Version 3.7.1
961 * The new network code has been improved to build with older versions
962 of glibc.
963 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
964 to Tommie Gannert for this patch.
966 2006-01-30, Version 3.7.0
967 * The `battery' plugin has been added. It collects information about
968 laptop batteries..
969 * The MySQL plugin has been improved: It now writes two more RRD
970 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
971 * The `cpufreq' plugin now reads another file since the file it did
972 read so far causes much overhead in the kernel. Also, you need root
973 to read the old file, but not to read the new one.
974 * The `hddtemp' plugin can now be configured to connect to another
975 address and/or port than localhost.
976 * The `df' plugin now prefers `statvfs' over `statfs'.
977 * The network code has been rewritten. collectd now supports unicast
978 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
979 be set in the configfile.
981 2006-01-24, Version 3.6.2
982 * Due to a bug in the configfile handling collectd wouldn't start in
983 client mode. This released fixes this.
985 2006-01-20, Version 3.6.1
986 * Due to a bug in `configure.in' all modules and the binary were
987 linked against `libmysqlclient'. This issue is solved by this
988 release.
990 2006-01-17, Version 3.6.0
991 * A config file has been added. This allows for loading only specific
992 plugins.
993 * A `df' plugin has been added.
994 * A `mysql' plugin has been added.
995 * The `ping' plugin doesn't entirely give up hope when a socket error
996 occurred, but will back of and increase the intervals between tries.
998 2006-01-21, Version 3.5.2
999 * Fixed yet another bug in the signal handling.. Stupid typo..
1000 * Improved the ping plugin to not give up on socket errors (backport
1001 from 3.6.0).
1003 2005-12-18, Version 3.5.1
1004 * The PID-file is now deleted correctly when shutting down the daemon.
1005 * SIGINT and SIGTERM are now handled correctly.
1007 2005-12-16, Version 3.5.0 (Revision 326)
1008 * A bug in the `load' module under Solaris has been fixed.
1009 * The `users' module has been contributed by Sebastian Harl. It counts
1010 currently logged in users.
1011 * The CPU module now works under FreeBSD without the use of
1012 `libstatgrab', however SMP support is missing.
1013 * The default directories for the RRD files and the PID file now
1014 depend on the compile time setting of `localstatedir'.
1016 2005-11-15, Version 3.4.0 (Revision 236)
1017 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1018 from gentoo's bugzilla for writing the patch.
1019 * The build dependency for librrd has been removed. Binaries built
1020 without librrd are client-only and will multicast their value as
1021 with the `-c' argument.
1022 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1023 * The newly introduced `-f' switch prevents daemon initialization
1024 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1025 Barcellos for this patch.
1027 2005-11-04, Version 3.3.0 (Revision 216)
1028 * New modules have been added:
1029 - `serial', for monitoring traffic on the serial interfaces
1030 - `nfs', for graphing NFS procedure calls
1031 - `tape', traffic from/to tape devices
1032 * The memory.rrd now accepts more than 4Gig of memory.
1034 2005-10-26, Version 3.2.0 (Revision 200)
1035 * Support for graphing the processes has been added (thanks to Lyonel
1036 Vincent)
1037 * If reading from hddtemp fails collectd will increase the time
1038 between polls up to one day.
1039 * The init.d files have been improved.
1040 * Problems with the spec file have been fixed.
1042 2005-10-16, Version 3.1.0 (Revision 194)
1043 * Added the `setsid' syscall to the startup code.
1044 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1046 2005-09-30, Version 3.0.0 (Revision 184)
1047 * The ability to send/receive data to/from the network (think
1048 multicast) has been added.
1049 * Modules have been split up into shared libraries can be loaded at
1050 runtime. The biggest advantage is that the core program doesn't need
1051 to be linked against an external library.
1052 * A patch by George Kargiotakis has been applied: It fixes the sensors
1053 behaviour then more than one sensor is being queried.
1055 2005-09-16, Version 2.1.0 (Revision 172)
1056 * A module for swap statistics has been added.
1058 2005-09-09, Version 2.0.0 (Revision 135)
1059 * Filenames can no longer be configured at program startup. The only
1060 options as of this version are the directory and ping hosts.
1061 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1062 Soft-IRQ statistics are added to `System'.
1063 * Diskstats now collect read and write bytes, not sectors.
1064 * Ping statistics can now be collected for more than one host. There
1065 is no default any more: If no host is given no host will be pinged.
1066 * A self-written patch for libping has been applied so it builds
1067 cleanly.
1069 2005-09-01, Version 1.8.1 (Revision 123)
1070 * Much improved configure-script: libraries and features may now be
1071 disabled.
1072 * More detailed warnings/error messages when RRD update fails.
1074 2005-08-29, Version 1.8.0:
1075 * Support for collecting disk statistics under Solaris.
1077 2005-08-25, Version 1.7.0:
1078 * Support for libstatgrab[1] for load, memory usage and network
1079 traffic. CPU- and disk-usage are not (yet) supported, since
1080 libstatgrab returns insufficient information. I will contact the
1081 authors.
1082 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1083 aren't necessarily counted linear which is now handled correctly.
1084 [1]: http://www.i-scream.org/libstatgrab/
1086 2005-08-21, Version 1.6.0:
1087 * Basic support for Solaris: System load and cpu-usage can be
1088 collected under Solaris, too. Other stats will follow later.
1089 * Many fixes in the autoconf-script
1090 * Collection/Museum scripts have been added under contrib/museum
1091 * collectd may now be started in unprivileged mode, though ping
1092 statistics will not work.
1094 2005-07-17, Version 1.5.1:
1095 * Diskstats-RRDs now use major/minor for naming. Some systems have
1096 weird strings as disk-names..
1098 2005-07-17, Version 1.5:
1099 * A new module, diskstats, has been added. It collects information
1100 about the disks and partitions.
1102 2005-07-11, Version 1.4.2:
1103 * The meminfo module has been changed to work with more platforms
1104 and/or kernel versions.
1106 2005-07-10, Version 1.4.1: Correct traffic stats
1107 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1108 forgot to correct when I changed that module.
1110 2005-07-09, Version 1.4: More traffic stats
1111 * Traffic is now collected for all interfaces that can be found
1112 * Temperature-statistics are read from lm-sensors if available
1114 2005-07-08, Version 1.3: CPU stats
1115 * Collecting CPU statistics now
1117 2004-07-12, Version 1.2: Using syslog
1118 * collectd is now using the syslog facility to report errors, warnings
1119 and the like..
1120 * The default directory is now /var/db/collectd
1122 2004-07-10, Version 1.1: Minor changes
1123 * Nothing really useful to say ;)
1125 2004-07-09, Version 1.0: Initial Version
1126 * The following modules are provided:
1127 * Load average
1128 * Ping time
1129 * Traffic
1130 * Memory info
