1 2009-05-09, Version 4.5.4
2 * Build system, various plugins: Many build fixes for FreeBSD,
3 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
4 for many fixes and providing a build system for many platforms,
5 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
6 providing an OpenBSD system.
7 * collectd: Fix a potential race condition when creating directories.
8 * battery plugin: Don't complain about a missing directory every
10 * dns plugin: Slight portability fixes.
11 * exec plugin: Allow executed programs to close STDERR. Thanks to
12 Thorsten von Eicken for reporting this problem.
13 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
14 Tomasz Pala for the patch.
15 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
17 * rrdtool plugin: Fix a possible race condition: If the network plugin
18 is initialized and dispatches a value before the rrdtool plugin is
19 initialized, the daemon may crash.
20 * memory plugin: Fix a potential problem under Solaris.
22 2009-03-18, Version 4.6.2
23 * collectd: Some Solaris utility code has been improved.
24 * filter subsystem: Allow `Chains' without default targets.
25 * liboping: A patch to comply with strict aliasing rules has been
27 * timediff match: Fix a typo: The match was registered with a wrong
28 name which prevented this match to be used as documented. Thanks to
29 Bruno Prémont for finding this problem.
30 * bind plugin: Fix collection of the cached RR sets. The number of RR
31 sets currently in the cache was collected as a counter value, which
32 is nonsense. Thanks to Bruno Prémont for implementing this.
33 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
34 primarily BSDs, don't take it well and crash.
35 * oracle plugin: Portability to 64 bit systems has been improved.
36 * postgresql plugin: The default configuration has been improved.
37 * rrdtool plugin: Fix a possible race condition: If the network plugin
38 is brought and dispatches a value before the rrdtool plugin is
39 initialized, the daemon may crash.
41 2009-02-22, Version 4.6.1
42 * collectd: Many documentation fixes.
43 * Collectd::Unixsock: Error handling has been improved.
44 * regex match: Don't link with the PCRE library.
45 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
46 for finding and fixing most of them.
47 * ipmi plugin: Fix an off-by-one error which could cause segmentation
48 faults. Thanks to Peter Holik for his patch.
50 2009-02-16, Version 4.6.0
51 * collectd: Added the `filter chain' infrastructure, which allows the
52 user to use `matches' and `targets' to control value processing.
53 * collectd: The new `-T' command line argument allows more in-depth
54 testing of a configuration. Thanks to Doug MacEachern for the patch.
55 * collectd-nagios: The Nagios integration command has been updated to
56 use libcollectdclient. The `percentage' aggregation function has
57 been added. Thanks to Fabian Linzberger for the patch.
58 * libcollectdclient: A library which abstracts communication with the
59 unixsock plugin for clients has been added.
60 * regex match: Match values by their identifies using regular
62 * timediff match: Match for values with an invalid timestamp.
63 * value match: Select values by their data sources' values.
64 * notification target: Create and dispatch a notification.
65 * replace target: Replace parts of an identifier using regular
67 * set target: Set (overwrite) entire parts of an identifier.
68 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
69 statistics, allowing very detailed name server statistics. Thanks to
70 Bruno Prémont for this plugin.
71 * cpu plugin: Report `interrupt' separately when using
72 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
73 example for native OpenBSD support, has been added. Thanks to Simon
75 * csv plugin: Make it possible to write values to STDOUT instead of
76 files. This is meant for testing purposes mostly. The output written
77 to STDOUT is compatible with the exec plugin. Thanks to Doug
78 MacEachern for the patch.
79 * curl plugin: This new plugin can be used to read web pages and parse
80 them using the same mechanism that's used in the tail plugin.
81 * dbi plugin: This new plugin allows you to connect to a variety of
82 relational databases and use SQL to gather custom statistics from
83 it. It is similar to the already existing PostgreSQL plugin but uses
84 libdbi to communicate with the database(s).
85 * interface plugin: Use the ignorelist framework when selecting /
86 ignoring interfaces. This allows one to use regular expressions to
87 select interfaces, too.
88 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
89 Thanks to Bruno Prémont for this patch.
90 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
92 * mysql plugin: Allow connecting to a database via the UNIX domain
93 socket, too. Thanks to Mirko Buffoni for the patch.
94 * network plugin: Further performance improvements for the receive
95 code. This hopefully will help very large setups.
96 * openvpn plugin: This new plugin collects statistics provided by the
97 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
98 * oracle plugin: This new plugin allows you to connect to an Oracle
99 database and use SQL to gather custom statistics from it. It is
100 similar to the already existing PostgreSQL plugin.
101 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
103 * perl plugin: Export the newly added plugin_write() to Perl plugins.
104 * perl plugin: Added support for `notification meta data'.
105 * perl plugin: Added support for the `filter chain' infrastructure by
106 allowing plugins to register `matches' and `targets'.
107 * postgresql plugin: The preferred configuration syntax has been
108 updated to be in line with the syntax used by the new dbi and oracle
109 plugins. The compatibility code for the old syntax is present.
110 Support for the new `Result' blocks and the interval parameter has
112 * processes plugin: Stacksize and virtual memory usage statistics have
113 been added. Portability fixes.
114 * rrdcached plugin: This new plugin uses the (still in development)
115 RRD accelerator daemon, rrdcached. This daemon works very similar to
116 the original rrdtool plugin of collectd, but adds some more nice
118 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
121 2009-02-22, Version 4.5.3
122 * build system: The check for libupsclient even when `pkg-config' is
124 * collectd: Fix error handling in the global cache.
125 * Collectd::Unixsock: Error handling has been improved.
126 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
128 * ipmi plugin: Fix an off-by-one error which could cause segmentation
129 faults. Thanks to Peter Holik for his patch.
130 * tcpconns plugin: An endianness problem has been fixed in the *BSD
131 code. Thanks to "thated" for reporting this.
133 2009-01-02, Version 4.5.2
134 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
135 file may be in both locations, especially when the database was
136 installed in a non-standard path. Thanks to Dusty Doris for
138 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
139 Solaris, in the configure script automatically.
140 * build system, tcpconns plugin: Check for `kvm_nlist' and
141 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
142 library with similar functions to the BSD variant, but doesn't
143 provide these necessary functions.
144 * collectd.conf(5): Various fixes and clarifications.
145 * collectd: Remove a GNUism (unnamed unions), thus improving
147 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
148 This solves portability problems, especially for Solaris.
149 * dns plugin: Fix a portability problem with NetBSD.
150 * filecount plugin: Fix an off-by-one error. This error may cause a
152 * network plugin: Fix the handling of `type' in the network protocol.
153 Due to a programming mistake, only 4 or 8 bytes would be copied to a
154 much larger buffer. This caused the `type' to be transferred much
155 more often than necessary. In some cases, e. g. the `cpu' and
156 `cpufreq' plugins being used at the same time, data may be corrupted
157 in those files. Thanks to Bruno Prémont for debugging and reporting
159 * processes plugin: Fix a possible segmentation fault when specifying
160 invalid configuration options.
161 * unixsock plugin: Make sure the initialization function is run only
162 once. This resolves a file descriptor leak under systems which run
163 the initialization more than once, such as Solaris.
165 2008-10-16, Version 4.5.1
166 * build system: Change `--enable-<plugin>' to abort with an error if
167 dependencies are not met. Thanks to Bruno Prémont for the patch.
168 Also, the poisoning of various string functions has been restricted
170 * collectd: Fix a memory leak in the global value cache. With every
171 *missing* value a couple of bytes would be leaked. Another memory
172 leak in the configuration handling code has been fixed. Thanks to
173 Niraj Tolia for reporting these issues.
174 * collectd: Fix an off-by-one error in the ignorelist functionality.
175 When using regular expressions, the last character would be missing,
176 possibly matching differently from what one would expect.
177 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
179 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
180 Linzberger for reporting the bug.
181 * iptables plugin: Fix an off-by-one error. If a string was just one
182 character too long, it was truncated instead of reporting an error.
183 * network plugin: Fix a memory leak in the configuration handling
184 code. Thanks to Niraj Tolia for reporting this issue.
185 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
186 * postgresql plugin: Don't reopen connection during reinitialization.
187 This fixes a bug under Solaris and potentially other platforms.
188 Missing calls to `PQclear' have been added, too. This fixes memory
189 leaks. Thanks to ``Admin'' for reporting these bugs.
190 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
192 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
193 problems with some `libc's. Thanks to Matthias Lay for reporting the
196 2008-09-04, Version 4.5.0
197 * collectd: Added the ability to flush certain identifiers.
198 * collectd: The concept of `notification meta data' has been
200 * filecount plugin: The new filecount plugin counts the number of
201 files in a directory and its subdirectories.
202 * ipmi plugin: Sensor names have been changed to ensure unique names.
203 Notifications upon added and removed sensors can now be generated.
204 * notify_desktop plugin: This new plugin sends notifications to the
205 X desktop using the structure defined in the `Desktop Notification
207 * notify_email plugin: This new plugin sends out notifications via
208 email, using the `esmtp' library.
209 * onewire plugin: The new experimental(!) onewire plugin reads values,
210 such as temperatures, from sensors connected to the computer via the
212 * perl plugin: Improved synchronized access to internal data structures
213 and fixed a possible dead-lock.
214 * perl plugin: Added the ability to flush certain identifiers and marked
215 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
217 * perl plugin: Added the ability to configure Perl plugins.
218 * postgresql plugin: The new postgresql plugin collects statistics
219 about or from a PostgreSQL database.
220 * processes plugin: The `ProcessMatch' option has been added.
221 * rrdtool plugin: Implement throttling of the `update queue' to lessen
223 * tcpconns plugin: This plugin has been ported to OpenBSD.
224 * thermal plugin: The new thermal plugin collects system temperatures
225 using Linux ACPI thermal zone data.
227 2009-01-02, Version 4.4.5
228 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
229 file may be in both locations, especially when the database was
230 installed in a non-standard path. Thanks to Dusty Doris for
232 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
233 Solaris, in the configure script automatically.
234 * collectd.conf(5): Various fixes and clarifications.
235 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
236 portability problems, especially for Solaris.
237 * dns plugin: Fix a portability problem with NetBSD.
238 * network plugin: Fix the handling of `type' in the network protocol.
239 Due to a programming mistake, only 4 or 8 bytes would be copied to a
240 much larger buffer. This caused the `type' to be transferred much
241 more often than necessary. In some cases, e. g. the `cpu' and
242 `cpufreq' plugins being used at the same time, data may be corrupted
243 in those files. Thanks to Bruno Prémont for debugging and reporting
245 * unixsock plugin: Make sure the initialization function is run only
246 once. This resolves a file descriptor leak under systems which run
247 the initialization more than once, such as Solaris.
249 2008-10-16, Version 4.4.4
250 * build system: Change `--enable-<plugin>' to abort with an error if
251 dependencies are not met. Thanks to Bruno Prémont for the patch.
252 Also, the poisoning of various string functions has been restricted
254 * collectd: Fix a memory leak in the global value cache. With every
255 *missing* value a couple of bytes would be leaked. Another memory
256 leak in the configuration handling code has been fixed. Thanks to
257 Niraj Tolia for reporting these issues.
258 * collectd: Fix an off-by-one error in the ignorelist functionality.
259 When using regular expressions, the last character would be missing,
260 possibly matching differently from what one would expect.
261 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
263 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
264 Linzberger for reporting the bug.
265 * network plugin: Fix a memory leak in the configuration handling
266 code. Thanks to Niraj Tolia for reporting this issue.
267 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
268 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
269 problems with some `libc's. Thanks to Matthias Lay for reporting the
272 2008-09-01, Version 4.4.3
273 * collectd: Fix a memory leak in the threshold checking code.
274 * memcached plugin: Fix a too short timeout and a related file

281 * collectd: Try even harder to determine the endianess of the
282 architecture collectd is being built on.
283 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
285 * dns plugin: Fix compilation errors with BIND versions 19991001
287 * network plugin: Bugfix in the init routine: The init function
288 cleared a buffer regardless of its contents. This could lead to lost
289 values under Solaris.
290 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
291 * vserver plugin: Remove usage of the thread-unsafe `readdir'
293 * wireless plugin: Work around incorrect noise and power values
294 returned by some broken drivers.
296 2008-06-03, Version 4.4.1
297 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
298 to kyrone for reporting this.
299 * collectd: Fixed min/max output in notifications generated by
301 * collectd-nagios: Fix the protocol used to communicate with the
303 * perl plugin: Fail noisily, but don't shutdown the daemon, if
304 initialization has errors. An issue with Perl 5.10 has been fixed.
305 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
306 René Rebe and Siegmund Gorr for reporting this.
308 2008-05-06, Version 4.4.0
309 * collectd: Internal code cleanups.
310 * collectd: Added support for a `Flush' command in the unixsock and
311 exec plugins. This command can be used to force a plugin (or all) to
312 flush its values to disk.
313 * collectd: Thresholds can now be configured to apply to one data
314 source only, making it possible to configure different thresholds
315 for each data source.
316 * apache, nginx plugins: Added the possibility to disable host and/or
318 * ascent plugin: The new ascent plugin reads and parses the statistics
319 page of an Ascent server.

324 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
325 sensor values via IPMI, the intelligent platform management
327 * iptables plugin: The iptc library that is used by the iptables
328 plugin has been added to the distribution, because it is not
329 provided by all distributions and removed from at least one.
330 * powerdns plugin: The new powerdns plugin reads statistics from an
331 authoritative or a recursing PowerDNS name server.
332 * rrdtool plugin: The size of the files generated with the default
333 configuration has been decreased.
334 * tail plugin: The new tail plugin can be used to gather statistics by
335 continuously reading from log files.
336 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
337 TeamSpeak2 server and collects statistics about the number of users
338 and number of channels.
339 * users plugin: Support for the statgrab library has been added.
340 * vmem plugin: The new vmem plugin collects very detailed statistics
341 about the virtual memory subsystem of Linux.

362 * build system: Improved detection of several libraries, especially if
363 they are in non-standard paths.
364 * build system: Portability fixes: Automatically define "_REENTRANT"
365 if the libc expects it.
366 * collectd: Error and warning messages have been improved.
367 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
369 * apache plugin: Allocate new memory when reading a webpage instead of
370 using a buffer of static size.
371 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
373 * hddtemp plugin: Error and warning messages have been improved.
374 * sensors plugin: Fix sensor collection for some chip types.
376 2008-03-29, Version 4.3.2
377 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
378 `Persist' threshold options.
379 * collectd: Fix handling of missing values in the global value cache.
380 * collectd: Improved error messages when parsing the configuration.

385 2008-03-05, Version 4.3.1
386 * exec plugin: Set supplementary group IDs.
388 + Use `memcpy' when constructing/parsing a package to avoid
389 alignment problems on weird architectures, such as Sparc.
390 + Translate doubles to/from the x86 byte representation to ensure
391 cross-platform compatibility.
392 * ping plugin: Correct the handling of the `TTL' setting.
393 * swap plugin: Reapply a patch for Solaris.
394 * tcpconns plugin: Portability improvements.
396 2008-02-18, Version 4.3.0
397 * collectd: Notifications have been added to the daemon. Notifications
398 are status messages that may be associated with a data instance.
399 * collectd: Threshold checking has been added to the daemon. This
400 means that you can configure threshold values for each data
401 instance. If this threshold is exceeded a notification will be
403 * collectd: The new `FQDNLookup' option tells the daemon to use the
404 full qualified domain name as the hostname, not just the host part
405 es returned by `gethostname(2)'.
406 * collectd: Support for more than one `TypesDB' file has been added.
407 This is useful when one such file is included in a package but one
408 wants to add custom type definitions.
409 * collectd: The `Include' config option has been expanded to handle
410 entire directories and shell wildcards.
411 * collectdmon: The new `collectdmon' binary detects when collectd
412 terminates and automatically restarts it again.
413 * csv plugin: The CSV plugin is now able to store counter values as a
414 rate, using the `StoreRates' configuration option.
415 * exec plugin: Handling of notifications has been added and the
416 ability to pass arguments to the executed programs has been added.
417 * hddtemp plugin: The new `TranslateDevicename' option lets you
418 disable the translation from device names to major-minor-numbers.
419 * logfile plugin: Handling of notifications has been added.
420 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
421 domain name lookups in this plugin.
422 * perl plugin: Many internal changes added support for handling multiple
423 threads making the plugin reasonably usable inside collectd. The API has
424 been extended to support notifications and export global variables to
425 Perl plugins; callbacks now have to be identified by name rather than a
426 pointer to a subroutine. The plugin is no longer experimental.
427 * uuid plugin: The new UUID plugin sets the hostname to an unique
428 identifier for this host. This is meant for setups where each client
429 may migrate to another physical host, possibly going through one or
430 more name changes in the process. Thanks to Richard Jones from
431 Red Hat's Emerging Technology group for this plugin.
432 * libvirt: The new libvirt plugin uses the `libvirt' library to query
433 CPU, disk and network statistics about guest systems on the same
434 physical server. Thanks to Richard Jones from Red Hat's Emerging
435 Technology group for this plugin.
437 2008-04-22, Version 4.2.7
438 * build system: Improved detection of several libraries, especially if
439 they are in non-standard paths.
440 * build system: Portability fixes: Automatically define "_REENTRANT"
441 if the libc expects it.
442 * collectd: Error and warning messages have been improved.
443 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
445 * apache plugin: Allocate new memory when reading a webpage instead of
446 using a buffer of static size.
447 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
449 * hddtemp plugin: Error and warning messages have been improved.
450 * sensors plugin: Fix sensor collection for some chip types.

455 * unixsock plugin: Fix mixed input and output operation on streams.
456 * wireless plugin: Fix reading noise value.
458 2008-03-04, Version 4.2.5
459 * apache plugin: Improved initialization and error messages.
460 * exec plugin: Set supplementary group IDs.
462 + Create separate threads for reading from the socket and parsing
463 and dispatching incoming packets. Versions prior to this may have
464 problems in high-load situations, where the socket receive buffers
465 overflows, resulting in gaps in the data.
466 + Use `memcpy' when constructing/parsing a package to avoid
467 alignment problems on weird architectures, such as Sparc.
468 + Translate doubles to/from the x86 byte representation to ensure
469 cross-platform compatibility.
470 * ping plugin: Correct the handling of the `TTL' setting.
471 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
472 * swap plugin: Reapply a patch for Solaris.
473 * tcpconns plugin: Portability improvements.
475 2008-01-21, Version 4.2.4
476 * unixsock plugin: A bug in the unixsock plugin caused it not to set
477 the permission on the socket as documented in the manpage. Thanks to
478 Evgeny Chukreev for fixing this issue.
479 * collectd: The documentation has been improved.
481 2007-12-28, Version 4.2.3
482 * sensors plugin: Updated the plugin to build and work with version 3
483 of the libsensors library.
485 2007-12-15, Version 4.2.2
486 * nginx plugin: Incorrect comparison of strings lead to a segfault
487 when using the plugin. Thanks to Saulius Grigaliunas for fixing
489 * logfile plugin: The config option `Timestamp' was handled
490 incorrectly and basically always active. Thanks to Luke Heberling
493 2007-11-08, Version 4.2.1
494 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
496 * snmp plugin: Fix a memory leak.
498 2007-10-27, Version 4.2.0
499 * collectd: The new config option `Include' lets you include other
500 configfiles and thus split up your config into smaller parts. This
501 may be especially interesting for the snmp plugin to keep the data
502 definitions separate from the host definitions.
503 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
504 (number of connections, octets and packets for each service and
505 destination). Thanks to Sebastian Harl for this plugin.
506 * memcached plugin: The new `memcached' plugin connects to a memcached
507 daemon process and collects statistics of this distributed caching
508 system. Thanks to Antony Dovgal for contributing this plugin.
509 * nginx plugin: The new `nginx' plugin reads the status page of an
510 nginx daemon and saves the handled connections and requests.
511 * perl plugin: Many changes, including the added `EnableDebugger'
512 config option which lets you debug your Perl plugins more easily.
513 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
514 be more thread-safe otherwise by locking calls to the library.
515 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
516 correct the values returned by SNMP-agents. If a <data> block is
517 defined as `table' the instance is now optional. The sequence number
518 is used as the type-instance in this case. The new `InstancePrefix'
519 option allows to add arbitrary prefixes to the type-instance.
520 * tcpconns plugin: The new `tcpconns' plugin collects the number of
521 certain TCP connections and what state they're in. This can be used
522 to see how many connections your FTP server has to handle or how
523 many outgoing connections your mailserver has open.
525 2008-01-11, Version 4.1.6
526 * unixsock plugin: A bug in the unixsock plugin caused it not to set

570 with the broken GNU version of `strerror_r'.
571 * collectd: Write an error message to STDERR when loading of a plugin
573 * apcups plugin: Fix the `types' used to submit the values: They still
574 has an `apcups_' prefix which doesn't work anymore.
575 * rrdtool plugin: Create new RRD-files with the `begin' time set to
576 whatever the client thinks is `now'..
578 2007-09-01, Version 4.1.0
579 * Build system: The build system has been changed to automatically
580 disable all plugins, which are missing dependencies. The dependency
581 checking has been removed from the plugins themselves to remove
583 * Flexible interval: The interval of collected data is now sent along
584 with the data itself over the network, so that the interval-settings
585 of server and clients no longer needs to match.
586 * netlink plugin: The new `netlink' plugin connects to the Linux
587 kernel using a netlink socket and uses it to query information about
588 interfaces, qdiscs and classes.
589 * rrdtool plugin: The cache is now dumped to disk in an extra thread
590 to not block data collection.
591 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
592 network devices, such as switches, routers, thermometers, rack
593 monitoring servers, etc. The collectd-snmp(5) manpage documents this
595 * unixsock plugin: Added the `LISTVAL' command.
596 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
597 of music played with xmms.
599 2007-09-28, Version 4.0.9

616 * documentation: Some typos have been fixed and some information has
618 * build system: Many fixes for detecting libraries in unusual places,
619 such as on RedHat systems. The affected libraries are `libcurl',
620 `libmysql', and `libupsclient'.
621 * network plugin: Allow the `Port' option to be specified as a number
622 (i. e. without quotes).
623 * nut plugin: A fix allows linking the nut plugin against
624 libupsclient, version >= 2.2.0.
625 * processes plugin: Fix a potential segmentation fault.
627 2007-07-30, Version 4.0.6
628 * sensors plugin: Fix the ignorelist functionality: Only the `type
629 instance' was used to match against the list, but the documentation
630 told otherwise. This release fixes the code, so it complies with the
632 * syslog plugin: Call `openlog' right when the plugin is loaded, so
633 configuration messages will end up in the logging facility.
634 * conrtib/fedora: The contributed specfile for Fedora has been
637 2007-07-05, Version 4.0.5

661 Setting a comment in the configfile will no longer cause a
664 2007-06-03, Version 4.0.0
665 * collectd: The plugin-infrastructure has been changed to allow for
666 more types of plugins, namely `write' and `log' plugins.
667 * collectd: The read-function has been changed to read many plugins in
668 parallel, using threads. Thus, plugins generally need to use
669 thread-safe functions from now on.
670 * collectd: The '-t' command line options allows to perform syntax tests
671 of the configuration file and exit immediately.
672 * csv plugin: The new `csv' plugin handles output to `comma separated
674 * rrdtool plugin: The new `rrdtool' plugin handles output to
675 RRD-files. Data can be cached to combine multiple updates into one
676 write to increase IO-performance.
677 * network plugin: The new `network' plugin handles IO via the network.
678 It implements a different, much more extensible protocol which can
679 combine many values in one packet, decreasing the number of UDP-
680 packets being sent. It can read from and send to the network and
681 with the appropriate configuration even forward packets to other
683 * unixsock plugin: The new `unixsock' plugin provides an interface to
684 communicate with the daemon while it is running. Right now the
685 commands `GETVAL' and `PUTVAL' are implemented, but more are to
687 * perl plugin: The new `perl' plugin allows you to write extensions
688 for collectd in the scripting-language Perl.
689 * logfile plugin: The new `logfile' plugin writes logmessages to files
691 * syslog plugin: The new `syslog' plugin sends logmessages to the
692 system's syslog daemon.

694 entropy currently being available to the system.
695 * exec plugin: The new `exec' plugin forks child processes and reads
696 back values provided by the forked processes.
697 * iptables plugin: The new `iptables' plugin reads counters from
698 iptables rules. Thanks to Sjoerd van der Berg for contributing this
700 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
701 to Peter Holik for contributing this plugin.
702 * nut plugin: The new `nut' plugin connects the upsd of the `network
703 ups tools' and reads information about the connected UPS.
704 * apache plugin: Support for lighttpd's `BusyServers' (aka.
705 connections) field was added by Florent Monbillard.
706 * collectd-nagios: The new `collectd-nagios' binary queries values
707 from collectd, parses them and exits according to Nagios-standards.
708 * manpages: The manpages have been improved a lot.
710 2007-09-28, Version 3.11.7
711 * wireless plugin: Correct the handling of cards returning signal and

718 * configure: Added `AC_SYS_LARGEFILE' for LFS.
719 * ntpd plugin: Fix a potential buffer overflow.
720 * processes plugin: Fix a bug when run under Linux 2.4. All processes
721 were accounted as `zombies'.
723 2007-04-10, Version 3.11.4
724 * dns plugin: Change the order of includes to make the plugin compile
727 2007-03-30, Version 3.11.3
728 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
729 of the unused `COLLECT_KSTAT'.
731 2007-02-11, Version 3.11.2
732 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
733 NULL-pointer may have been passed to `printf' which causes a
734 segfault with some libcs.
736 2007-02-10, Version 3.11.1
737 * df plugin: Some wrong defines have been fixed so the plugin works
739 * dns plugin: The usage of a struct has been fixed to work with
741 * processes plugin: Some missing defines have been added so the plugin
742 compiles cleanly under FreeBSD and presumably other UNIXes.
744 2006-12-22, Version 3.11.0
745 * collectd: The new command line option `-P' makes it easier for
746 distributors to change the location of PID-files.
747 * collectd: The daemon shuts down faster now which makes it easier to
748 write init.d-scripts for it.
749 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
750 caused problems every now and then.
751 * df plugin: New config options allow to ignore certain mountpoints,
752 filesystem types or devices.
753 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
754 and interprets it. It collects traffic as well as qtype, opcode and
756 * email plugin: Sebastian Harl has contributed this plugin which
757 counts received mails in categories (e. g. ham, spam, virus), spam
758 score (as given by SpamAssassin) and check types.
759 * mbmon plugin: Flavio Stanchina has contributed this plugin which
760 uses `mbmon' to gather information from sensors on the motherboard.
761 * processes plugin: Collect detailed statistics for configured
762 processes, that's process and thread count, CPU usage, resident
763 segment size and pagefaults.
764 * multimeter plugin: Peter Holik contributed a new plugin which
766 * sensors plugin: Lubos Stanek has put much effort into improving this
767 plugin, including `extended naming', collection of voltage values
768 and the possibility to ignore certain values.
770 2006-12-21, Version 3.10.4
771 * Max Kellermann has identified a bug in the server routine: When
772 opening a socket fails the daemon will (re)try opening the socket in
773 an endless loop, ultimately leading to a `EMFILE' error.
775 2006-11-04, Version 3.10.3
776 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
777 ntpd's reply was sent in more than one packet, the buffer size was
778 calculated incorrectly, resulting in the reading of uninitialized or
781 2006-11-01, Version 3.10.2
782 * The sample config file has been improved.
783 * Errors in the manpages have been corrected.
784 * The ping-plugin now adds hosts during initialization, not during
785 startup. This speeds up startup when no network connectivity is
786 available. Also, the hosts are being added later when the network is
788 * Improved BSD-support for the df-plugin.
789 * Fixed syntax errors in the swap-plugin for Mac OS X.
790 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
792 * Don't disable the mysql-plugin if connecting to the database fails
793 during initialization. Instead, try again in increasing intervals.
795 2006-07-19, Version 3.10.1
796 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
797 the apcups cannot be reached, unconnected sockets will pile up and
798 eventually lead to `Too many open files' errors.
800 2006-07-09, Version 3.10.0
801 * The `disk' plugin has been ported to Darwin.
802 * The `battery' plugin should work on many Apple computers now.
803 * The `traffic' plugin can now ignore certain interfaces. Also,
804 statistics for sent/received packets and errors have been added.
805 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
806 to Anthony Gialluca for contributing this plugin and providing me
807 with a test environment :)
808 * A plugin for monitoring an NTP instance and the local clock drift
811 2006-06-25, Version 3.9.4
812 * The Solaris code in the `swap' plugin has been changed to reflect
813 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
815 * The debugging system has been fixed to work with the Sun libc.
816 * When built without librrd the variable `operating_mode' could be
817 uninitialized. Thanks to David Elliot for reporting the bug.
819 2006-06-01, Version 3.9.3
820 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
821 operating systems also profit from the changes, but I wasn't able to
823 * Changed the build system to find the netinet-includes under FreeBSD
824 and therefore successfully build the `liboping' library there.
826 2006-05-09, Version 3.9.2
827 * Applied a patch to the `liboping' library. Due to a bug in the
828 sequence checking the `ping' plugin stopped working after
829 approximately 7.6 days.
831 2006-05-09, Version 3.8.5
832 * Applied a patch to the `liboping' library. Due to a bug in the
833 sequence checking the `ping' plugin stopped working after
834 approximately 7.6 days.
836 2006-04-21, Version 3.9.1
837 * Build issues with Solaris and possible other architectures have been
839 * Problems when building the `apache'-plugin without `libcurl' have

850 strength, link quality and noise ratio..
851 * A plugin for Apple hardware sensors has been added.
852 * An option to compile collectd with different `step' and `heartbeat'
853 settings has been added. The size of RRAs is no longer static but
854 calculated based on the settings for `step' and `width'.
855 * The `ping' plugin can now be configured to use a certain TTL.
856 * A plugin to monitor the hardware sensors of Apple computers has been
858 * The plugins `cpu', `memory', `processes' and `traffic' have been
859 ported to Mach/Darwin (Mac OS X).
860 * The `log mode' has been contributed by Christophe Kalt. It writes
861 the data into text files rather than RRD files.
863 2006-04-09, Version 3.8.4
864 * Applied patch by Vincent Stehlé which improves the disk-name
865 resolution in the `hddtemp' plugin for Linux systems.
867 2006-04-02, Version 3.8.3
868 * Applied a patch by James Byers: The MySQL plugin was not working
869 with MySQL 5.0.2 or later.
871 2006-03-14, Version 3.8.2
872 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
873 the GNU libc, because it points to `/etc/fstab' rather than
876 2006-03-13, Version 3.8.1
877 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
878 * Fixes in the debian `postinst' and `init.d' scripts.
880 2006-03-09, Version 3.8.0
881 * The `ping' plugin no longer uses `libping' but a self written
882 library named `liboping'. With this library it's possible to ping
883 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
885 2006-02-18, Version 3.7.2
886 * A simple bug in the `battery' plugin has been fixed. It should now
887 work with ACPI based batteries as well. Thanks to Sebastian for
889 * Fixing a bug that prevented collectd to be built without librrd.
890 Thanks to Werner Heuser for reporting it.
892 2006-02-04, Version 3.7.1
893 * The new network code has been improved to build with older versions

898 2006-01-30, Version 3.7.0
899 * The `battery' plugin has been added. It collects information about
901 * The MySQL plugin has been improved: It now writes two more RRD
902 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
903 * The `cpufreq' plugin now reads another file since the file it did
904 read so far causes much overhead in the kernel. Also, you need root
905 to read the old file, but not to read the new one.
906 * The `hddtemp' plugin can now be configured to connect to another
907 address and/or port than localhost.
908 * The `df' plugin now prefers `statvfs' over `statfs'.
909 * The network code has been rewritten. collectd now supports unicast
910 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
911 be set in the configfile.
913 2006-01-24, Version 3.6.2
914 * Due to a bug in the configfile handling collectd wouldn't start in
915 client mode. This released fixes this.
917 2006-01-20, Version 3.6.1
918 * Due to a bug in `configure.in' all modules and the binary were
919 linked against `libmysqlclient'. This issue is solved by this
922 2006-01-17, Version 3.6.0
923 * A config file has been added. This allows for loading only specific
925 * A `df' plugin has been added.
926 * A `mysql' plugin has been added.
927 * The `ping' plugin doesn't entirely give up hope when a socket error
928 occurred, but will back of and increase the intervals between tries.
930 2006-01-21, Version 3.5.2
931 * Fixed yet another bug in the signal handling.. Stupid typo..
932 * Improved the ping plugin to not give up on socket errors (backport
935 2005-12-18, Version 3.5.1

939 2005-12-16, Version 3.5.0 (Revision 326)
940 * A bug in the `load' module under Solaris has been fixed.
941 * The `users' module has been contributed by Sebastian Harl. It counts
942 currently logged in users.
943 * The CPU module now works under FreeBSD without the use of
944 `libstatgrab', however SMP support is missing.
945 * The default directories for the RRD files and the PID file now
946 depend on the compile time setting of `localstatedir'.
948 2005-11-15, Version 3.4.0 (Revision 236)
949 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
950 from gentoo's bugzilla for writing the patch.
951 * The build dependency for librrd has been removed. Binaries built
952 without librrd are client-only and will multicast their value as
953 with the `-c' argument.
954 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
955 * The newly introduced `-f' switch prevents daemon initialization
956 (forking, closing standard filehandles, etc.) Thanks to Alvaro
957 Barcellos for this patch.
959 2005-11-04, Version 3.3.0 (Revision 216)
960 * New modules have been added:
961 - `serial', for monitoring traffic on the serial interfaces
962 - `nfs', for graphing NFS procedure calls
963 - `tape', traffic from/to tape devices

976 * Support for hddtemp has been added (thanks to Vincent Stehlé)
978 2005-09-30, Version 3.0.0 (Revision 184)
979 * The ability to send/receive data to/from the network (think
980 multicast) has been added.
981 * Modules have been split up into shared libraries can be loaded at
982 runtime. The biggest advantage is that the core program doesn't need
983 to be linked against an external library.
984 * A patch by George Kargiotakis has been applied: It fixes the sensors
985 behaviour then more than one sensor is being queried.
987 2005-09-16, Version 2.1.0 (Revision 172)
988 * A module for swap statistics has been added.
990 2005-09-09, Version 2.0.0 (Revision 135)
991 * Filenames can no longer be configured at program startup. The only
992 options as of this version are the directory and ping hosts.
993 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
994 Soft-IRQ statistics are added to `System'.
995 * Diskstats now collect read and write bytes, not sectors.
996 * Ping statistics can now be collected for more than one host. There
997 is no default any more: If no host is given no host will be pinged.
998 * A self-written patch for libping has been applied so it builds
1001 2005-09-01, Version 1.8.1 (Revision 123)
1002 * Much improved configure-script: libraries and features may now be
1004 * More detailed warnings/error messages when RRD update fails.
1006 2005-08-29, Version 1.8.0:
1007 * Support for collecting disk statistics under Solaris.
1009 2005-08-25, Version 1.7.0:
1010 * Support for libstatgrab[1] for load, memory usage and network
1011 traffic. CPU- and disk-usage are not (yet) supported, since
1012 libstatgrab returns insufficient information. I will contact the
1014 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1015 aren't necessarily counted linear which is now handled correctly.
