1 2009-03-18, Version 4.6.2
2 * collectd: Some Solaris utility code has been improved.
3 * filter subsystem: Allow `Chains' without default targets.
4 * liboping: A patch to comply with strict aliasing rules has been
6 * timediff match: Fix a typo: The match was registered with a wrong
7 name which prevented this match to be used as documented. Thanks to
8 Bruno Prémont for finding this problem.
9 * bind plugin: Fix collection of the cached RR sets. The number of RR
10 sets currently in the cache was collected as a counter value, which
11 is nonsense. Thanks to Bruno Prémont for implementing this.
12 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
13 primarily BSDs, don't take it well and crash.
14 * oracle plugin: Portability to 64 bit systems has been improved.
15 * postgresql plugin: The default configuration has been improved.
16 * rrdtool plugin: Fix a possible race condition: If the network plugin
17 is brought and dispatches a value before the rrdtool plugin is
18 initialized, the daemon may crash.
20 2009-02-22, Version 4.6.1
21 * collectd: Many documentation fixes.
22 * Collectd::Unixsock: Error handling has been improved.
23 * regex match: Don't link with the PCRE library.
24 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
25 for finding and fixing most of them.
26 * ipmi plugin: Fix an off-by-one error which could cause segmentation
27 faults. Thanks to Peter Holik for his patch.
29 2009-02-16, Version 4.6.0
30 * collectd: Added the `filter chain' infrastructure, which allows the
31 user to use `matches' and `targets' to control value processing.
32 * collectd: The new `-T' command line argument allows more in-depth
33 testing of a configuration. Thanks to Doug MacEachern for the patch.
34 * collectd-nagios: The Nagios integration command has been updated to
35 use libcollectdclient. The `percentage' aggregation function has
36 been added. Thanks to Fabian Linzberger for the patch.
37 * libcollectdclient: A library which abstracts communication with the
38 unixsock plugin for clients has been added.
39 * regex match: Match values by their identifies using regular
41 * timediff match: Match for values with an invalid timestamp.
42 * value match: Select values by their data sources' values.
43 * notification target: Create and dispatch a notification.
44 * replace target: Replace parts of an identifier using regular
46 * set target: Set (overwrite) entire parts of an identifier.
47 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
48 statistics, allowing very detailed name server statistics. Thanks to
49 Bruno Prémont for this plugin.
50 * cpu plugin: Report `interrupt' separately when using
51 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
52 example for native OpenBSD support, has been added. Thanks to Simon
54 * csv plugin: Make it possible to write values to STDOUT instead of
55 files. This is meant for testing purposes mostly. The output written
56 to STDOUT is compatible with the exec plugin. Thanks to Doug
57 MacEachern for the patch.
58 * curl plugin: This new plugin can be used to read web pages and parse
59 them using the same mechanism that's used in the tail plugin.
60 * dbi plugin: This new plugin allows you to connect to a variety of
61 relational databases and use SQL to gather custom statistics from
62 it. It is similar to the already existing PostgreSQL plugin but uses
63 libdbi to communicate with the database(s).
64 * interface plugin: Use the ignorelist framework when selecting /
65 ignoring interfaces. This allows one to use regular expressions to
66 select interfaces, too.
67 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
68 Thanks to Bruno Prémont for this patch.
69 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
71 * mysql plugin: Allow connecting to a database via the UNIX domain
72 socket, too. Thanks to Mirko Buffoni for the patch.
73 * network plugin: Further performance improvements for the receive
74 code. This hopefully will help very large setups.
75 * openvpn plugin: This new plugin collects statistics provided by the
76 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
77 * oracle plugin: This new plugin allows you to connect to an Oracle
78 database and use SQL to gather custom statistics from it. It is
79 similar to the already existing PostgreSQL plugin.
80 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
82 * perl plugin: Export the newly added plugin_write() to Perl plugins.
83 * perl plugin: Added support for `notification meta data'.
84 * perl plugin: Added support for the `filter chain' infrastructure by
85 allowing plugins to register `matches' and `targets'.
86 * postgresql plugin: The preferred configuration syntax has been
87 updated to be in line with the syntax used by the new dbi and oracle
88 plugins. The compatibility code for the old syntax is present.
89 Support for the new `Result' blocks and the interval parameter has
91 * processes plugin: Stacksize and virtual memory usage statistics have
92 been added. Portability fixes.
93 * rrdcached plugin: This new plugin uses the (still in development)
94 RRD accelerator daemon, rrdcached. This daemon works very similar to
95 the original rrdtool plugin of collectd, but adds some more nice
97 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
100 2009-02-22, Version 4.5.3
101 * build system: The check for libupsclient even when `pkg-config' is
103 * collectd: Fix error handling in the global cache.
104 * Collectd::Unixsock: Error handling has been improved.
105 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
107 * ipmi plugin: Fix an off-by-one error which could cause segmentation
108 faults. Thanks to Peter Holik for his patch.
109 * tcpconns plugin: An endianness problem has been fixed in the *BSD
110 code. Thanks to "thated" for reporting this.
112 2009-01-02, Version 4.5.2
113 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
114 file may be in both locations, especially when the database was
115 installed in a non-standard path. Thanks to Dusty Doris for
117 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
118 Solaris, in the configure script automatically.
119 * build system, tcpconns plugin: Check for `kvm_nlist' and
120 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
121 library with similar functions to the BSD variant, but doesn't
122 provide these necessary functions.
123 * collectd.conf(5): Various fixes and clarifications.
124 * collectd: Remove a GNUism (unnamed unions), thus improving
126 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
127 This solves portability problems, especially for Solaris.
128 * dns plugin: Fix a portability problem with NetBSD.
129 * filecount plugin: Fix an off-by-one error. This error may cause a
131 * network plugin: Fix the handling of `type' in the network protocol.
132 Due to a programming mistake, only 4 or 8 bytes would be copied to a
133 much larger buffer. This caused the `type' to be transferred much
134 more often than necessary. In some cases, e. g. the `cpu' and
135 `cpufreq' plugins being used at the same time, data may be corrupted
136 in those files. Thanks to Bruno Prémont for debugging and reporting
138 * processes plugin: Fix a possible segmentation fault when specifying
139 invalid configuration options.
140 * unixsock plugin: Make sure the initialization function is run only
141 once. This resolves a file descriptor leak under systems which run
142 the initialization more than once, such as Solaris.
144 2008-10-16, Version 4.5.1
145 * build system: Change `--enable-<plugin>' to abort with an error if
146 dependencies are not met. Thanks to Bruno Prémont for the patch.
147 Also, the poisoning of various string functions has been restricted
149 * collectd: Fix a memory leak in the global value cache. With every
150 *missing* value a couple of bytes would be leaked. Another memory
151 leak in the configuration handling code has been fixed. Thanks to
152 Niraj Tolia for reporting these issues.
153 * collectd: Fix an off-by-one error in the ignorelist functionality.
154 When using regular expressions, the last character would be missing,
155 possibly matching differently from what one would expect.
156 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
158 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
159 Linzberger for reporting the bug.
160 * iptables plugin: Fix an off-by-one error. If a string was just one
161 character too long, it was truncated instead of reporting an error.
162 * network plugin: Fix a memory leak in the configuration handling
163 code. Thanks to Niraj Tolia for reporting this issue.
164 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
165 * postgresql plugin: Don't reopen connection during reinitialization.
166 This fixes a bug under Solaris and potentially other platforms.
167 Missing calls to `PQclear' have been added, too. This fixes memory
168 leaks. Thanks to ``Admin'' for reporting these bugs.
169 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
171 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
172 problems with some `libc's. Thanks to Matthias Lay for reporting the
175 2008-09-04, Version 4.5.0
176 * collectd: Added the ability to flush certain identifiers.
177 * collectd: The concept of `notification meta data' has been
179 * filecount plugin: The new filecount plugin counts the number of
180 files in a directory and its subdirectories.
181 * ipmi plugin: Sensor names have been changed to ensure unique names.
182 Notifications upon added and removed sensors can now be generated.
183 * notify_desktop plugin: This new plugin sends notifications to the
184 X desktop using the structure defined in the `Desktop Notification
186 * notify_email plugin: This new plugin sends out notifications via
187 email, using the `esmtp' library.
188 * onewire plugin: The new experimental(!) onewire plugin reads values,
189 such as temperatures, from sensors connected to the computer via the
191 * perl plugin: Improved synchronized access to internal data structures
192 and fixed a possible dead-lock.
193 * perl plugin: Added the ability to flush certain identifiers and marked
194 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
196 * perl plugin: Added the ability to configure Perl plugins.
197 * postgresql plugin: The new postgresql plugin collects statistics
198 about or from a PostgreSQL database.
199 * processes plugin: The `ProcessMatch' option has been added.
200 * rrdtool plugin: Implement throttling of the `update queue' to lessen
202 * tcpconns plugin: This plugin has been ported to OpenBSD.
203 * thermal plugin: The new thermal plugin collects system temperatures
204 using Linux ACPI thermal zone data.
206 2009-01-02, Version 4.4.5
207 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
208 file may be in both locations, especially when the database was
209 installed in a non-standard path. Thanks to Dusty Doris for
211 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
212 Solaris, in the configure script automatically.
213 * collectd.conf(5): Various fixes and clarifications.
214 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
215 portability problems, especially for Solaris.
216 * dns plugin: Fix a portability problem with NetBSD.
217 * network plugin: Fix the handling of `type' in the network protocol.
218 Due to a programming mistake, only 4 or 8 bytes would be copied to a
219 much larger buffer. This caused the `type' to be transferred much
220 more often than necessary. In some cases, e. g. the `cpu' and
221 `cpufreq' plugins being used at the same time, data may be corrupted
222 in those files. Thanks to Bruno Prémont for debugging and reporting
224 * unixsock plugin: Make sure the initialization function is run only
225 once. This resolves a file descriptor leak under systems which run
226 the initialization more than once, such as Solaris.
228 2008-10-16, Version 4.4.4
229 * build system: Change `--enable-<plugin>' to abort with an error if
230 dependencies are not met. Thanks to Bruno Prémont for the patch.
231 Also, the poisoning of various string functions has been restricted
233 * collectd: Fix a memory leak in the global value cache. With every
234 *missing* value a couple of bytes would be leaked. Another memory
235 leak in the configuration handling code has been fixed. Thanks to
236 Niraj Tolia for reporting these issues.
237 * collectd: Fix an off-by-one error in the ignorelist functionality.
238 When using regular expressions, the last character would be missing,
239 possibly matching differently from what one would expect.
240 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
242 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
243 Linzberger for reporting the bug.
244 * network plugin: Fix a memory leak in the configuration handling
245 code. Thanks to Niraj Tolia for reporting this issue.
246 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
247 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
248 problems with some `libc's. Thanks to Matthias Lay for reporting the
251 2008-09-01, Version 4.4.3
252 * collectd: Fix a memory leak in the threshold checking code.
253 * memcached plugin: Fix a too short timeout and a related file
255 * memory plugin: A typo in the libstatgrab code has been fixed.
256 * snmp plugin: Fix a possible memory leak.
258 2008-07-15, Version 4.4.2
259 * build system: Use pkg-config to detect the upsclient library.
260 * collectd: Try even harder to determine the endianess of the
261 architecture collectd is being built on.
262 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
264 * dns plugin: Fix compilation errors with BIND versions 19991001
266 * network plugin: Bugfix in the init routine: The init function
267 cleared a buffer regardless of its contents. This could lead to lost
268 values under Solaris.
269 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
270 * vserver plugin: Remove usage of the thread-unsafe `readdir'
272 * wireless plugin: Work around incorrect noise and power values
273 returned by some broken drivers.
275 2008-06-03, Version 4.4.1
276 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
277 to kyrone for reporting this.
278 * collectd: Fixed min/max output in notifications generated by
280 * collectd-nagios: Fix the protocol used to communicate with the
282 * perl plugin: Fail noisily, but don't shutdown the daemon, if
283 initialization has errors. An issue with Perl 5.10 has been fixed.
284 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
285 René Rebe and Siegmund Gorr for reporting this.
287 2008-05-06, Version 4.4.0
288 * collectd: Internal code cleanups.
289 * collectd: Added support for a `Flush' command in the unixsock and
290 exec plugins. This command can be used to force a plugin (or all) to
291 flush its values to disk.
292 * collectd: Thresholds can now be configured to apply to one data
293 source only, making it possible to configure different thresholds
294 for each data source.
295 * apache, nginx plugins: Added the possibility to disable host and/or
297 * ascent plugin: The new ascent plugin reads and parses the statistics
298 page of an Ascent server.
299 * cpu plugin: Support for the statgrab library has been added.
300 * disk plugin: The possibility to ignore certain disks or collect only
301 specific disks has been added.
302 * disk plugin: Support for the statgrab library has been added.
303 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
304 sensor values via IPMI, the intelligent platform management
306 * iptables plugin: The iptc library that is used by the iptables
307 plugin has been added to the distribution, because it is not
308 provided by all distributions and removed from at least one.
309 * powerdns plugin: The new powerdns plugin reads statistics from an
310 authoritative or a recursing PowerDNS name server.
311 * rrdtool plugin: The size of the files generated with the default
312 configuration has been decreased.
313 * tail plugin: The new tail plugin can be used to gather statistics by
314 continuously reading from log files.
315 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
316 TeamSpeak2 server and collects statistics about the number of users
317 and number of channels.
318 * users plugin: Support for the statgrab library has been added.
319 * vmem plugin: The new vmem plugin collects very detailed statistics
320 about the virtual memory subsystem of Linux.
322 2008-08-30, Version 4.3.4
323 * Build system: Improved detection of and linking with the statgrab
325 * collectd: Portability fixes, especially to determine endianess more
327 * Various plugins: Fix format strings.
328 * disk plugin: A fix for giving disks under Linux 2.4 the right names
329 again has been applied.
330 * memcached plugin: Fix a too short timeout and a related file
332 * memory plugin: A typo in the libstatgrab code has been fixed.
333 * network plugin: A fix in the initialization function solves problems

336 * vserver plugin: A thread-unsafe function has been replaced.
337 * wireless plugin: A work-around for broken wireless drivers has been
340 2008-04-22, Version 4.3.3
341 * build system: Improved detection of several libraries, especially if
342 they are in non-standard paths.
343 * build system: Portability fixes: Automatically define "_REENTRANT"
344 if the libc expects it.
345 * collectd: Error and warning messages have been improved.
346 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
348 * apache plugin: Allocate new memory when reading a webpage instead of
349 using a buffer of static size.
350 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
352 * hddtemp plugin: Error and warning messages have been improved.
353 * sensors plugin: Fix sensor collection for some chip types.
355 2008-03-29, Version 4.3.2
356 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
357 `Persist' threshold options.
358 * collectd: Fix handling of missing values in the global value cache.
359 * collectd: Improved error messages when parsing the configuration.
360 * sensors plugin: Fix temperature collection with libsensors4.

362 * wireless plugin: Fix reading noise value.
364 2008-03-05, Version 4.3.1
365 * exec plugin: Set supplementary group IDs.
367 + Use `memcpy' when constructing/parsing a package to avoid
368 alignment problems on weird architectures, such as Sparc.
369 + Translate doubles to/from the x86 byte representation to ensure
370 cross-platform compatibility.
371 * ping plugin: Correct the handling of the `TTL' setting.
372 * swap plugin: Reapply a patch for Solaris.
373 * tcpconns plugin: Portability improvements.
375 2008-02-18, Version 4.3.0
376 * collectd: Notifications have been added to the daemon. Notifications
377 are status messages that may be associated with a data instance.
378 * collectd: Threshold checking has been added to the daemon. This
379 means that you can configure threshold values for each data
380 instance. If this threshold is exceeded a notification will be
382 * collectd: The new `FQDNLookup' option tells the daemon to use the
383 full qualified domain name as the hostname, not just the host part
384 es returned by `gethostname(2)'.
385 * collectd: Support for more than one `TypesDB' file has been added.
386 This is useful when one such file is included in a package but one
387 wants to add custom type definitions.
388 * collectd: The `Include' config option has been expanded to handle
389 entire directories and shell wildcards.
390 * collectdmon: The new `collectdmon' binary detects when collectd
391 terminates and automatically restarts it again.
392 * csv plugin: The CSV plugin is now able to store counter values as a
393 rate, using the `StoreRates' configuration option.
394 * exec plugin: Handling of notifications has been added and the
395 ability to pass arguments to the executed programs has been added.
396 * hddtemp plugin: The new `TranslateDevicename' option lets you
397 disable the translation from device names to major-minor-numbers.
398 * logfile plugin: Handling of notifications has been added.
399 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
400 domain name lookups in this plugin.
401 * perl plugin: Many internal changes added support for handling multiple
402 threads making the plugin reasonably usable inside collectd. The API has
403 been extended to support notifications and export global variables to
404 Perl plugins; callbacks now have to be identified by name rather than a
405 pointer to a subroutine. The plugin is no longer experimental.
406 * uuid plugin: The new UUID plugin sets the hostname to an unique
407 identifier for this host. This is meant for setups where each client
408 may migrate to another physical host, possibly going through one or
409 more name changes in the process. Thanks to Richard Jones from
410 Red Hat's Emerging Technology group for this plugin.
411 * libvirt: The new libvirt plugin uses the `libvirt' library to query
412 CPU, disk and network statistics about guest systems on the same
413 physical server. Thanks to Richard Jones from Red Hat's Emerging
414 Technology group for this plugin.
416 2008-04-22, Version 4.2.7
417 * build system: Improved detection of several libraries, especially if
418 they are in non-standard paths.
419 * build system: Portability fixes: Automatically define "_REENTRANT"
420 if the libc expects it.
421 * collectd: Error and warning messages have been improved.
422 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
424 * apache plugin: Allocate new memory when reading a webpage instead of
425 using a buffer of static size.
426 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
428 * hddtemp plugin: Error and warning messages have been improved.
429 * sensors plugin: Fix sensor collection for some chip types.
431 2008-03-29, Version 4.2.6
432 * collectd: Improved error messages when parsing the configuration.
433 * sensors plugin: Fix temperature collection with libsensors4.
434 * unixsock plugin: Fix mixed input and output operation on streams.
435 * wireless plugin: Fix reading noise value.
437 2008-03-04, Version 4.2.5
438 * apache plugin: Improved initialization and error messages.
439 * exec plugin: Set supplementary group IDs.
441 + Create separate threads for reading from the socket and parsing
442 and dispatching incoming packets. Versions prior to this may have
443 problems in high-load situations, where the socket receive buffers
444 overflows, resulting in gaps in the data.
445 + Use `memcpy' when constructing/parsing a package to avoid
446 alignment problems on weird architectures, such as Sparc.
447 + Translate doubles to/from the x86 byte representation to ensure
448 cross-platform compatibility.
449 * ping plugin: Correct the handling of the `TTL' setting.
450 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
451 * swap plugin: Reapply a patch for Solaris.
452 * tcpconns plugin: Portability improvements.
454 2008-01-21, Version 4.2.4
455 * unixsock plugin: A bug in the unixsock plugin caused it not to set
456 the permission on the socket as documented in the manpage. Thanks to
457 Evgeny Chukreev for fixing this issue.
458 * collectd: The documentation has been improved.
460 2007-12-28, Version 4.2.3
461 * sensors plugin: Updated the plugin to build and work with version 3
462 of the libsensors library.
464 2007-12-15, Version 4.2.2
465 * nginx plugin: Incorrect comparison of strings lead to a segfault
466 when using the plugin. Thanks to Saulius Grigaliunas for fixing
468 * logfile plugin: The config option `Timestamp' was handled
469 incorrectly and basically always active. Thanks to Luke Heberling
472 2007-11-08, Version 4.2.1
473 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
475 * snmp plugin: Fix a memory leak.
477 2007-10-27, Version 4.2.0
478 * collectd: The new config option `Include' lets you include other
479 configfiles and thus split up your config into smaller parts. This
480 may be especially interesting for the snmp plugin to keep the data
481 definitions separate from the host definitions.
482 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
483 (number of connections, octets and packets for each service and
484 destination). Thanks to Sebastian Harl for this plugin.
485 * memcached plugin: The new `memcached' plugin connects to a memcached
486 daemon process and collects statistics of this distributed caching
487 system. Thanks to Antony Dovgal for contributing this plugin.
488 * nginx plugin: The new `nginx' plugin reads the status page of an
489 nginx daemon and saves the handled connections and requests.
490 * perl plugin: Many changes, including the added `EnableDebugger'
491 config option which lets you debug your Perl plugins more easily.
492 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
493 be more thread-safe otherwise by locking calls to the library.
494 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
495 correct the values returned by SNMP-agents. If a <data> block is
496 defined as `table' the instance is now optional. The sequence number
497 is used as the type-instance in this case. The new `InstancePrefix'
498 option allows to add arbitrary prefixes to the type-instance.
499 * tcpconns plugin: The new `tcpconns' plugin collects the number of
500 certain TCP connections and what state they're in. This can be used
501 to see how many connections your FTP server has to handle or how
502 many outgoing connections your mailserver has open.
504 2008-01-11, Version 4.1.6

555 whatever the client thinks is `now'..
557 2007-09-01, Version 4.1.0
558 * Build system: The build system has been changed to automatically
559 disable all plugins, which are missing dependencies. The dependency
560 checking has been removed from the plugins themselves to remove
562 * Flexible interval: The interval of collected data is now sent along
563 with the data itself over the network, so that the interval-settings
564 of server and clients no longer needs to match.
565 * netlink plugin: The new `netlink' plugin connects to the Linux
566 kernel using a netlink socket and uses it to query information about
567 interfaces, qdiscs and classes.
568 * rrdtool plugin: The cache is now dumped to disk in an extra thread
569 to not block data collection.
570 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
571 network devices, such as switches, routers, thermometers, rack
572 monitoring servers, etc. The collectd-snmp(5) manpage documents this
574 * unixsock plugin: Added the `LISTVAL' command.
575 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
576 of music played with xmms.

595 * documentation: Some typos have been fixed and some information has
597 * build system: Many fixes for detecting libraries in unusual places,
598 such as on RedHat systems. The affected libraries are `libcurl',
599 `libmysql', and `libupsclient'.
600 * network plugin: Allow the `Port' option to be specified as a number
601 (i. e. without quotes).
602 * nut plugin: A fix allows linking the nut plugin against
603 libupsclient, version >= 2.2.0.
604 * processes plugin: Fix a potential segmentation fault.
606 2007-07-30, Version 4.0.6
607 * sensors plugin: Fix the ignorelist functionality: Only the `type
608 instance' was used to match against the list, but the documentation
609 told otherwise. This release fixes the code, so it complies with the
611 * syslog plugin: Call `openlog' right when the plugin is loaded, so
612 configuration messages will end up in the logging facility.
613 * conrtib/fedora: The contributed specfile for Fedora has been
616 2007-07-05, Version 4.0.5

640 Setting a comment in the configfile will no longer cause a
643 2007-06-03, Version 4.0.0
644 * collectd: The plugin-infrastructure has been changed to allow for
645 more types of plugins, namely `write' and `log' plugins.
646 * collectd: The read-function has been changed to read many plugins in
647 parallel, using threads. Thus, plugins generally need to use
648 thread-safe functions from now on.
649 * collectd: The '-t' command line options allows to perform syntax tests
650 of the configuration file and exit immediately.
651 * csv plugin: The new `csv' plugin handles output to `comma separated
653 * rrdtool plugin: The new `rrdtool' plugin handles output to
654 RRD-files. Data can be cached to combine multiple updates into one
655 write to increase IO-performance.
656 * network plugin: The new `network' plugin handles IO via the network.
657 It implements a different, much more extensible protocol which can
658 combine many values in one packet, decreasing the number of UDP-
659 packets being sent. It can read from and send to the network and
660 with the appropriate configuration even forward packets to other
662 * unixsock plugin: The new `unixsock' plugin provides an interface to
663 communicate with the daemon while it is running. Right now the
664 commands `GETVAL' and `PUTVAL' are implemented, but more are to
666 * perl plugin: The new `perl' plugin allows you to write extensions
667 for collectd in the scripting-language Perl.

680 to Peter Holik for contributing this plugin.
681 * nut plugin: The new `nut' plugin connects the upsd of the `network
682 ups tools' and reads information about the connected UPS.
683 * apache plugin: Support for lighttpd's `BusyServers' (aka.
684 connections) field was added by Florent Monbillard.
685 * collectd-nagios: The new `collectd-nagios' binary queries values
686 from collectd, parses them and exits according to Nagios-standards.
687 * manpages: The manpages have been improved a lot.
689 2007-09-28, Version 3.11.7
690 * wireless plugin: Correct the handling of cards returning signal and

699 * processes plugin: Fix a bug when run under Linux 2.4. All processes
700 were accounted as `zombies'.
702 2007-04-10, Version 3.11.4
703 * dns plugin: Change the order of includes to make the plugin compile
706 2007-03-30, Version 3.11.3
707 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
708 of the unused `COLLECT_KSTAT'.
710 2007-02-11, Version 3.11.2
711 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
712 NULL-pointer may have been passed to `printf' which causes a
713 segfault with some libcs.
715 2007-02-10, Version 3.11.1
716 * df plugin: Some wrong defines have been fixed so the plugin works
718 * dns plugin: The usage of a struct has been fixed to work with
720 * processes plugin: Some missing defines have been added so the plugin
721 compiles cleanly under FreeBSD and presumably other UNIXes.
723 2006-12-22, Version 3.11.0
724 * collectd: The new command line option `-P' makes it easier for
725 distributors to change the location of PID-files.
726 * collectd: The daemon shuts down faster now which makes it easier to
727 write init.d-scripts for it.
728 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
729 caused problems every now and then.
730 * df plugin: New config options allow to ignore certain mountpoints,
731 filesystem types or devices.
732 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
733 and interprets it. It collects traffic as well as qtype, opcode and
735 * email plugin: Sebastian Harl has contributed this plugin which
736 counts received mails in categories (e. g. ham, spam, virus), spam
737 score (as given by SpamAssassin) and check types.
738 * mbmon plugin: Flavio Stanchina has contributed this plugin which
739 uses `mbmon' to gather information from sensors on the motherboard.
740 * processes plugin: Collect detailed statistics for configured
741 processes, that's process and thread count, CPU usage, resident
742 segment size and pagefaults.
743 * multimeter plugin: Peter Holik contributed a new plugin which
745 * sensors plugin: Lubos Stanek has put much effort into improving this
746 plugin, including `extended naming', collection of voltage values
747 and the possibility to ignore certain values.
749 2006-12-21, Version 3.10.4
750 * Max Kellermann has identified a bug in the server routine: When
751 opening a socket fails the daemon will (re)try opening the socket in
752 an endless loop, ultimately leading to a `EMFILE' error.
754 2006-11-04, Version 3.10.3
755 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
756 ntpd's reply was sent in more than one packet, the buffer size was
757 calculated incorrectly, resulting in the reading of uninitialized or
760 2006-11-01, Version 3.10.2
761 * The sample config file has been improved.
762 * Errors in the manpages have been corrected.
763 * The ping-plugin now adds hosts during initialization, not during
764 startup. This speeds up startup when no network connectivity is
765 available. Also, the hosts are being added later when the network is
767 * Improved BSD-support for the df-plugin.
768 * Fixed syntax errors in the swap-plugin for Mac OS X.
769 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
771 * Don't disable the mysql-plugin if connecting to the database fails
772 during initialization. Instead, try again in increasing intervals.
774 2006-07-19, Version 3.10.1
775 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
776 the apcups cannot be reached, unconnected sockets will pile up and
777 eventually lead to `Too many open files' errors.
779 2006-07-09, Version 3.10.0
780 * The `disk' plugin has been ported to Darwin.
781 * The `battery' plugin should work on many Apple computers now.
782 * The `traffic' plugin can now ignore certain interfaces. Also,
783 statistics for sent/received packets and errors have been added.
784 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
785 to Anthony Gialluca for contributing this plugin and providing me
786 with a test environment :)
787 * A plugin for monitoring an NTP instance and the local clock drift
790 2006-06-25, Version 3.9.4
791 * The Solaris code in the `swap' plugin has been changed to reflect
792 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
794 * The debugging system has been fixed to work with the Sun libc.
795 * When built without librrd the variable `operating_mode' could be
796 uninitialized. Thanks to David Elliot for reporting the bug.
798 2006-06-01, Version 3.9.3
799 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
800 operating systems also profit from the changes, but I wasn't able to
802 * Changed the build system to find the netinet-includes under FreeBSD
803 and therefore successfully build the `liboping' library there.
805 2006-05-09, Version 3.9.2
806 * Applied a patch to the `liboping' library. Due to a bug in the
807 sequence checking the `ping' plugin stopped working after
808 approximately 7.6 days.
810 2006-05-09, Version 3.8.5
811 * Applied a patch to the `liboping' library. Due to a bug in the
812 sequence checking the `ping' plugin stopped working after
813 approximately 7.6 days.
815 2006-04-21, Version 3.9.1
816 * Build issues with Solaris and possible other architectures have been
818 * Problems when building the `apache'-plugin without `libcurl' have
820 * A bug in the `ping' plugin has been fixed. Sorry folks.
822 2006-04-02, Version 3.9.0

829 strength, link quality and noise ratio..
830 * A plugin for Apple hardware sensors has been added.
831 * An option to compile collectd with different `step' and `heartbeat'
832 settings has been added. The size of RRAs is no longer static but
833 calculated based on the settings for `step' and `width'.
834 * The `ping' plugin can now be configured to use a certain TTL.
835 * A plugin to monitor the hardware sensors of Apple computers has been
837 * The plugins `cpu', `memory', `processes' and `traffic' have been
838 ported to Mach/Darwin (Mac OS X).
839 * The `log mode' has been contributed by Christophe Kalt. It writes
840 the data into text files rather than RRD files.
842 2006-04-09, Version 3.8.4
843 * Applied patch by Vincent Stehlé which improves the disk-name
844 resolution in the `hddtemp' plugin for Linux systems.
846 2006-04-02, Version 3.8.3
847 * Applied a patch by James Byers: The MySQL plugin was not working
848 with MySQL 5.0.2 or later.
850 2006-03-14, Version 3.8.2
851 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
852 the GNU libc, because it points to `/etc/fstab' rather than
855 2006-03-13, Version 3.8.1
856 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
857 * Fixes in the debian `postinst' and `init.d' scripts.
859 2006-03-09, Version 3.8.0
860 * The `ping' plugin no longer uses `libping' but a self written
861 library named `liboping'. With this library it's possible to ping
862 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
864 2006-02-18, Version 3.7.2
865 * A simple bug in the `battery' plugin has been fixed. It should now
866 work with ACPI based batteries as well. Thanks to Sebastian for
868 * Fixing a bug that prevented collectd to be built without librrd.
869 Thanks to Werner Heuser for reporting it.
871 2006-02-04, Version 3.7.1
872 * The new network code has been improved to build with older versions

877 2006-01-30, Version 3.7.0
878 * The `battery' plugin has been added. It collects information about
880 * The MySQL plugin has been improved: It now writes two more RRD
881 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
882 * The `cpufreq' plugin now reads another file since the file it did
883 read so far causes much overhead in the kernel. Also, you need root
884 to read the old file, but not to read the new one.
885 * The `hddtemp' plugin can now be configured to connect to another
886 address and/or port than localhost.
887 * The `df' plugin now prefers `statvfs' over `statfs'.
888 * The network code has been rewritten. collectd now supports unicast
889 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
890 be set in the configfile.
892 2006-01-24, Version 3.6.2
893 * Due to a bug in the configfile handling collectd wouldn't start in
894 client mode. This released fixes this.
896 2006-01-20, Version 3.6.1
897 * Due to a bug in `configure.in' all modules and the binary were
898 linked against `libmysqlclient'. This issue is solved by this
901 2006-01-17, Version 3.6.0
902 * A config file has been added. This allows for loading only specific
904 * A `df' plugin has been added.
905 * A `mysql' plugin has been added.
906 * The `ping' plugin doesn't entirely give up hope when a socket error
907 occurred, but will back of and increase the intervals between tries.
909 2006-01-21, Version 3.5.2
910 * Fixed yet another bug in the signal handling.. Stupid typo..
911 * Improved the ping plugin to not give up on socket errors (backport
914 2005-12-18, Version 3.5.1

918 2005-12-16, Version 3.5.0 (Revision 326)
919 * A bug in the `load' module under Solaris has been fixed.
920 * The `users' module has been contributed by Sebastian Harl. It counts
921 currently logged in users.
922 * The CPU module now works under FreeBSD without the use of
923 `libstatgrab', however SMP support is missing.
924 * The default directories for the RRD files and the PID file now
925 depend on the compile time setting of `localstatedir'.
927 2005-11-15, Version 3.4.0 (Revision 236)
928 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
929 from gentoo's bugzilla for writing the patch.
930 * The build dependency for librrd has been removed. Binaries built
931 without librrd are client-only and will multicast their value as
932 with the `-c' argument.
933 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
934 * The newly introduced `-f' switch prevents daemon initialization
935 (forking, closing standard filehandles, etc.) Thanks to Alvaro
936 Barcellos for this patch.
938 2005-11-04, Version 3.3.0 (Revision 216)
939 * New modules have been added:
940 - `serial', for monitoring traffic on the serial interfaces
941 - `nfs', for graphing NFS procedure calls
942 - `tape', traffic from/to tape devices

953 2005-10-16, Version 3.1.0 (Revision 194)
954 * Added the `setsid' syscall to the startup code.
955 * Support for hddtemp has been added (thanks to Vincent Stehlé)
957 2005-09-30, Version 3.0.0 (Revision 184)
958 * The ability to send/receive data to/from the network (think
959 multicast) has been added.
960 * Modules have been split up into shared libraries can be loaded at
961 runtime. The biggest advantage is that the core program doesn't need
962 to be linked against an external library.
963 * A patch by George Kargiotakis has been applied: It fixes the sensors
964 behaviour then more than one sensor is being queried.
966 2005-09-16, Version 2.1.0 (Revision 172)
967 * A module for swap statistics has been added.
969 2005-09-09, Version 2.0.0 (Revision 135)
970 * Filenames can no longer be configured at program startup. The only
971 options as of this version are the directory and ping hosts.
972 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
973 Soft-IRQ statistics are added to `System'.
974 * Diskstats now collect read and write bytes, not sectors.
975 * Ping statistics can now be collected for more than one host. There
976 is no default any more: If no host is given no host will be pinged.
977 * A self-written patch for libping has been applied so it builds
980 2005-09-01, Version 1.8.1 (Revision 123)
981 * Much improved configure-script: libraries and features may now be
983 * More detailed warnings/error messages when RRD update fails.
985 2005-08-29, Version 1.8.0:
986 * Support for collecting disk statistics under Solaris.
988 2005-08-25, Version 1.7.0:
989 * Support for libstatgrab[1] for load, memory usage and network
990 traffic. CPU- and disk-usage are not (yet) supported, since
991 libstatgrab returns insufficient information. I will contact the
993 * Improved the CPU-initialization code for Solaris. Apparently CPUs
994 aren't necessarily counted linear which is now handled correctly.
995 [1]: http://www.i-scream.org/libstatgrab/
997 2005-08-21, Version 1.6.0:
998 * Basic support for Solaris: System load and cpu-usage can be
999 collected under Solaris, too. Other stats will follow later.
1000 * Many fixes in the autoconf-script
1001 * Collection/Museum scripts have been added under contrib/museum
1002 * collectd may now be started in unprivileged mode, though ping
1003 statistics will not work.
1005 2005-07-17, Version 1.5.1:
1006 * Diskstats-RRDs now use major/minor for naming. Some systems have
1007 weird strings as disk-names..
1009 2005-07-17, Version 1.5:
1010 * A new module, diskstats, has been added. It collects information
1011 about the disks and partitions.
