1 2009-02-16, Version 4.6.0
2 * collectd: Added the `filter chain' infrastructure, which allows the
3 user to use `matches' and `targets' to control value processing.
4 * collectd: The new `-T' command line argument allows more in-depth
5 testing of a configuration. Thanks to Doug MacEachern for the patch.
6 * collectd-nagios: The Nagios integration command has been updated to
7 use libcollectdclient. The `percentage' aggregation function has
8 been added. Thanks to Fabian Linzberger for the patch.
9 * libcollectdclient: A library which abstracts communication with the
10 unixsock plugin for clients has been added.
11 * regex match: Match values by their identifies using regular
13 * timediff match: Match for values with an invalid timestamp.
14 * value match: Select values by their data sources' values.
15 * notification target: Create and dispatch a notification.
16 * replace target: Replace parts of an identifier using regular
18 * set target: Set (overwrite) entire parts of an identifier.
19 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
20 statistics, allowing very detailed name server statistics. Thanks to
21 Bruno Prémont for this plugin.
22 * cpu plugin: Report `interrupt' separately when using
23 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
24 example for native OpenBSD support, has been added. Thanks to Simon
26 * csv plugin: Make it possible to write values to STDOUT instead of
27 files. This is meant for testing purposes mostly. The output written
28 to STDOUT is compatible with the exec plugin. Thanks to Doug
29 MacEachern for the patch.
30 * curl plugin: This new plugin can be used to read web pages and parse
31 them using the same mechanism that's used in the tail plugin.
32 * dbi plugin: This new plugin allows you to connect to a variety of
33 relational databases and use SQL to gather custom statistics from
34 it. It is similar to the already existing PostgreSQL plugin but uses
35 libdbi to communicate with the database(s).
36 * interface plugin: Use the ignorelist framework when selecting /
37 ignoring interfaces. This allows one to use regular expressions to
38 select interfaces, too.
39 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
40 Thanks to Bruno Prémont for this patch.
41 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
43 * mysql plugin: Allow connecting to a database via the UNIX domain
44 socket, too. Thanks to Mirko Buffoni for the patch.
45 * network plugin: Further performance improvements for the receive
46 code. This hopefully will help very large setups.
47 * openvpn plugin: This new plugin collects statistics provided by the
48 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
49 * oracle plugin: This new plugin allows you to connect to an Oracle
50 database and use SQL to gather custom statistics from it. It is
51 similar to the already existing PostgreSQL plugin.
52 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
54 * perl plugin: Export the newly added plugin_write() to Perl plugins.
55 * perl plugin: Added support for `notification meta data'.
56 * perl plugin: Added support for the `filter chain' infrastructure by
57 allowing plugins to register `matches' and `targets'.
58 * postgresql plugin: The preferred configuration syntax has been
59 updated to be in line with the syntax used by the new dbi and oracle
60 plugins. The compatibility code for the old syntax is present.
61 Support for the new `Result' blocks and the interval parameter has
63 * processes plugin: Stacksize and virtual memory usage statistics have
64 been added. Portability fixes.
65 * rrdcached plugin: This new plugin uses the (still in development)
66 RRD accelerator daemon, rrdcached. This daemon works very similar to
67 the original rrdtool plugin of collectd, but adds some more nice
69 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
72 2009-02-22, Version 4.5.3
73 * build system: The check for libupsclient even when `pkg-config' is
75 * collectd: Fix error handling in the global cache.
76 * Collectd::Unixsock: Error handling has been improved.
77 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
79 * ipmi plugin: Fix an off-by-one error which could cause segmentation
80 faults. Thanks to Peter Holik for his patch.
81 * tcpconns plugin: An endianness problem has been fixed in the *BSD
82 code. Thanks to "thated" for reporting this.
84 2009-01-02, Version 4.5.2
85 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
86 file may be in both locations, especially when the database was
87 installed in a non-standard path. Thanks to Dusty Doris for
89 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
90 Solaris, in the configure script automatically.
91 * build system, tcpconns plugin: Check for `kvm_nlist' and
92 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
93 library with similar functions to the BSD variant, but doesn't
94 provide these necessary functions.
95 * collectd.conf(5): Various fixes and clarifications.
96 * collectd: Remove a GNUism (unnamed unions), thus improving
98 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
99 This solves portability problems, especially for Solaris.
100 * dns plugin: Fix a portability problem with NetBSD.
101 * filecount plugin: Fix an off-by-one error. This error may cause a
103 * network plugin: Fix the handling of `type' in the network protocol.
104 Due to a programming mistake, only 4 or 8 bytes would be copied to a
105 much larger buffer. This caused the `type' to be transferred much
106 more often than necessary. In some cases, e. g. the `cpu' and
107 `cpufreq' plugins being used at the same time, data may be corrupted
108 in those files. Thanks to Bruno Prémont for debugging and reporting
110 * processes plugin: Fix a possible segmentation fault when specifying
111 invalid configuration options.
112 * unixsock plugin: Make sure the initialization function is run only
113 once. This resolves a file descriptor leak under systems which run
114 the initialization more than once, such as Solaris.
116 2008-10-16, Version 4.5.1
117 * build system: Change `--enable-<plugin>' to abort with an error if
118 dependencies are not met. Thanks to Bruno Prémont for the patch.
119 Also, the poisoning of various string functions has been restricted
121 * collectd: Fix a memory leak in the global value cache. With every
122 *missing* value a couple of bytes would be leaked. Another memory
123 leak in the configuration handling code has been fixed. Thanks to
124 Niraj Tolia for reporting these issues.
125 * collectd: Fix an off-by-one error in the ignorelist functionality.
126 When using regular expressions, the last character would be missing,
127 possibly matching differently from what one would expect.
128 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
130 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
131 Linzberger for reporting the bug.
132 * iptables plugin: Fix an off-by-one error. If a string was just one
133 character too long, it was truncated instead of reporting an error.
134 * network plugin: Fix a memory leak in the configuration handling
135 code. Thanks to Niraj Tolia for reporting this issue.
136 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
137 * postgresql plugin: Don't reopen connection during reinitialization.
138 This fixes a bug under Solaris and potentially other platforms.
139 Missing calls to `PQclear' have been added, too. This fixes memory
140 leaks. Thanks to ``Admin'' for reporting these bugs.
141 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
143 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
144 problems with some `libc's. Thanks to Matthias Lay for reporting the
147 2008-09-04, Version 4.5.0
148 * collectd: Added the ability to flush certain identifiers.
149 * collectd: The concept of `notification meta data' has been
151 * filecount plugin: The new filecount plugin counts the number of
152 files in a directory and its subdirectories.
153 * ipmi plugin: Sensor names have been changed to ensure unique names.
154 Notifications upon added and removed sensors can now be generated.
155 * notify_desktop plugin: This new plugin sends notifications to the
156 X desktop using the structure defined in the `Desktop Notification
158 * notify_email plugin: This new plugin sends out notifications via
159 email, using the `esmtp' library.
160 * onewire plugin: The new experimental(!) onewire plugin reads values,
161 such as temperatures, from sensors connected to the computer via the
163 * perl plugin: Improved synchronized access to internal data structures
164 and fixed a possible dead-lock.
165 * perl plugin: Added the ability to flush certain identifiers and marked
166 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
168 * perl plugin: Added the ability to configure Perl plugins.
169 * postgresql plugin: The new postgresql plugin collects statistics
170 about or from a PostgreSQL database.
171 * processes plugin: The `ProcessMatch' option has been added.
172 * rrdtool plugin: Implement throttling of the `update queue' to lessen
174 * tcpconns plugin: This plugin has been ported to OpenBSD.
175 * thermal plugin: The new thermal plugin collects system temperatures
176 using Linux ACPI thermal zone data.
178 2009-01-02, Version 4.4.5
179 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
180 file may be in both locations, especially when the database was
181 installed in a non-standard path. Thanks to Dusty Doris for
183 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
184 Solaris, in the configure script automatically.
185 * collectd.conf(5): Various fixes and clarifications.
186 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
187 portability problems, especially for Solaris.
188 * dns plugin: Fix a portability problem with NetBSD.
189 * network plugin: Fix the handling of `type' in the network protocol.
190 Due to a programming mistake, only 4 or 8 bytes would be copied to a
191 much larger buffer. This caused the `type' to be transferred much
192 more often than necessary. In some cases, e. g. the `cpu' and
193 `cpufreq' plugins being used at the same time, data may be corrupted
194 in those files. Thanks to Bruno Prémont for debugging and reporting
196 * unixsock plugin: Make sure the initialization function is run only
197 once. This resolves a file descriptor leak under systems which run
198 the initialization more than once, such as Solaris.
200 2008-10-16, Version 4.4.4
201 * build system: Change `--enable-<plugin>' to abort with an error if
202 dependencies are not met. Thanks to Bruno Prémont for the patch.
203 Also, the poisoning of various string functions has been restricted
205 * collectd: Fix a memory leak in the global value cache. With every
206 *missing* value a couple of bytes would be leaked. Another memory
207 leak in the configuration handling code has been fixed. Thanks to
208 Niraj Tolia for reporting these issues.
209 * collectd: Fix an off-by-one error in the ignorelist functionality.
210 When using regular expressions, the last character would be missing,
211 possibly matching differently from what one would expect.
212 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
214 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
215 Linzberger for reporting the bug.
216 * network plugin: Fix a memory leak in the configuration handling
217 code. Thanks to Niraj Tolia for reporting this issue.
218 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
219 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
220 problems with some `libc's. Thanks to Matthias Lay for reporting the
223 2008-09-01, Version 4.4.3
224 * collectd: Fix a memory leak in the threshold checking code.
225 * memcached plugin: Fix a too short timeout and a related file

232 * collectd: Try even harder to determine the endianess of the
233 architecture collectd is being built on.
234 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
236 * dns plugin: Fix compilation errors with BIND versions 19991001
238 * network plugin: Bugfix in the init routine: The init function
239 cleared a buffer regardless of its contents. This could lead to lost
240 values under Solaris.
241 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
242 * vserver plugin: Remove usage of the thread-unsafe `readdir'
244 * wireless plugin: Work around incorrect noise and power values
245 returned by some broken drivers.
247 2008-06-03, Version 4.4.1
248 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
249 to kyrone for reporting this.
250 * collectd: Fixed min/max output in notifications generated by
252 * collectd-nagios: Fix the protocol used to communicate with the
254 * perl plugin: Fail noisily, but don't shutdown the daemon, if
255 initialization has errors. An issue with Perl 5.10 has been fixed.
256 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
257 René Rebe and Siegmund Gorr for reporting this.
259 2008-05-06, Version 4.4.0
260 * collectd: Internal code cleanups.
261 * collectd: Added support for a `Flush' command in the unixsock and
262 exec plugins. This command can be used to force a plugin (or all) to
263 flush its values to disk.
264 * collectd: Thresholds can now be configured to apply to one data
265 source only, making it possible to configure different thresholds
266 for each data source.
267 * apache, nginx plugins: Added the possibility to disable host and/or
269 * ascent plugin: The new ascent plugin reads and parses the statistics
270 page of an Ascent server.
271 * cpu plugin: Support for the statgrab library has been added.
272 * disk plugin: The possibility to ignore certain disks or collect only
273 specific disks has been added.
274 * disk plugin: Support for the statgrab library has been added.
275 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
276 sensor values via IPMI, the intelligent platform management
278 * iptables plugin: The iptc library that is used by the iptables
279 plugin has been added to the distribution, because it is not
280 provided by all distributions and removed from at least one.
281 * powerdns plugin: The new powerdns plugin reads statistics from an
282 authoritative or a recursing PowerDNS name server.
283 * rrdtool plugin: The size of the files generated with the default
284 configuration has been decreased.
285 * tail plugin: The new tail plugin can be used to gather statistics by
286 continuously reading from log files.
287 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
288 TeamSpeak2 server and collects statistics about the number of users
289 and number of channels.
290 * users plugin: Support for the statgrab library has been added.
291 * vmem plugin: The new vmem plugin collects very detailed statistics
292 about the virtual memory subsystem of Linux.

312 2008-04-22, Version 4.3.3
313 * build system: Improved detection of several libraries, especially if
314 they are in non-standard paths.
315 * build system: Portability fixes: Automatically define "_REENTRANT"
316 if the libc expects it.
317 * collectd: Error and warning messages have been improved.
318 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
320 * apache plugin: Allocate new memory when reading a webpage instead of
321 using a buffer of static size.
322 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
324 * hddtemp plugin: Error and warning messages have been improved.
325 * sensors plugin: Fix sensor collection for some chip types.
327 2008-03-29, Version 4.3.2
328 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
329 `Persist' threshold options.
330 * collectd: Fix handling of missing values in the global value cache.
331 * collectd: Improved error messages when parsing the configuration.

336 2008-03-05, Version 4.3.1
337 * exec plugin: Set supplementary group IDs.
339 + Use `memcpy' when constructing/parsing a package to avoid
340 alignment problems on weird architectures, such as Sparc.
341 + Translate doubles to/from the x86 byte representation to ensure
342 cross-platform compatibility.
343 * ping plugin: Correct the handling of the `TTL' setting.
344 * swap plugin: Reapply a patch for Solaris.
345 * tcpconns plugin: Portability improvements.
347 2008-02-18, Version 4.3.0
348 * collectd: Notifications have been added to the daemon. Notifications
349 are status messages that may be associated with a data instance.
350 * collectd: Threshold checking has been added to the daemon. This
351 means that you can configure threshold values for each data
352 instance. If this threshold is exceeded a notification will be
354 * collectd: The new `FQDNLookup' option tells the daemon to use the
355 full qualified domain name as the hostname, not just the host part
356 es returned by `gethostname(2)'.
357 * collectd: Support for more than one `TypesDB' file has been added.
358 This is useful when one such file is included in a package but one
359 wants to add custom type definitions.
360 * collectd: The `Include' config option has been expanded to handle
361 entire directories and shell wildcards.
362 * collectdmon: The new `collectdmon' binary detects when collectd
363 terminates and automatically restarts it again.
364 * csv plugin: The CSV plugin is now able to store counter values as a
365 rate, using the `StoreRates' configuration option.
366 * exec plugin: Handling of notifications has been added and the
367 ability to pass arguments to the executed programs has been added.
368 * hddtemp plugin: The new `TranslateDevicename' option lets you
369 disable the translation from device names to major-minor-numbers.
370 * logfile plugin: Handling of notifications has been added.
371 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
372 domain name lookups in this plugin.
373 * perl plugin: Many internal changes added support for handling multiple
374 threads making the plugin reasonably usable inside collectd. The API has
375 been extended to support notifications and export global variables to
376 Perl plugins; callbacks now have to be identified by name rather than a
377 pointer to a subroutine. The plugin is no longer experimental.
378 * uuid plugin: The new UUID plugin sets the hostname to an unique
379 identifier for this host. This is meant for setups where each client
380 may migrate to another physical host, possibly going through one or
381 more name changes in the process. Thanks to Richard Jones from
382 Red Hat's Emerging Technology group for this plugin.
383 * libvirt: The new libvirt plugin uses the `libvirt' library to query
384 CPU, disk and network statistics about guest systems on the same
385 physical server. Thanks to Richard Jones from Red Hat's Emerging
386 Technology group for this plugin.
388 2008-04-22, Version 4.2.7
389 * build system: Improved detection of several libraries, especially if
390 they are in non-standard paths.
391 * build system: Portability fixes: Automatically define "_REENTRANT"
392 if the libc expects it.
393 * collectd: Error and warning messages have been improved.
394 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
396 * apache plugin: Allocate new memory when reading a webpage instead of
397 using a buffer of static size.
398 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
400 * hddtemp plugin: Error and warning messages have been improved.

405 * sensors plugin: Fix temperature collection with libsensors4.
406 * unixsock plugin: Fix mixed input and output operation on streams.
407 * wireless plugin: Fix reading noise value.
409 2008-03-04, Version 4.2.5
410 * apache plugin: Improved initialization and error messages.
411 * exec plugin: Set supplementary group IDs.
413 + Create separate threads for reading from the socket and parsing
414 and dispatching incoming packets. Versions prior to this may have
415 problems in high-load situations, where the socket receive buffers
416 overflows, resulting in gaps in the data.
417 + Use `memcpy' when constructing/parsing a package to avoid
418 alignment problems on weird architectures, such as Sparc.
419 + Translate doubles to/from the x86 byte representation to ensure
420 cross-platform compatibility.
421 * ping plugin: Correct the handling of the `TTL' setting.
422 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
423 * swap plugin: Reapply a patch for Solaris.
424 * tcpconns plugin: Portability improvements.
426 2008-01-21, Version 4.2.4
427 * unixsock plugin: A bug in the unixsock plugin caused it not to set
428 the permission on the socket as documented in the manpage. Thanks to
429 Evgeny Chukreev for fixing this issue.
430 * collectd: The documentation has been improved.
432 2007-12-28, Version 4.2.3
433 * sensors plugin: Updated the plugin to build and work with version 3
434 of the libsensors library.
436 2007-12-15, Version 4.2.2
437 * nginx plugin: Incorrect comparison of strings lead to a segfault
438 when using the plugin. Thanks to Saulius Grigaliunas for fixing
440 * logfile plugin: The config option `Timestamp' was handled
441 incorrectly and basically always active. Thanks to Luke Heberling
444 2007-11-08, Version 4.2.1
445 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
447 * snmp plugin: Fix a memory leak.
449 2007-10-27, Version 4.2.0
450 * collectd: The new config option `Include' lets you include other
451 configfiles and thus split up your config into smaller parts. This
452 may be especially interesting for the snmp plugin to keep the data
453 definitions separate from the host definitions.
454 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
455 (number of connections, octets and packets for each service and
456 destination). Thanks to Sebastian Harl for this plugin.
457 * memcached plugin: The new `memcached' plugin connects to a memcached
458 daemon process and collects statistics of this distributed caching
459 system. Thanks to Antony Dovgal for contributing this plugin.
460 * nginx plugin: The new `nginx' plugin reads the status page of an
461 nginx daemon and saves the handled connections and requests.
462 * perl plugin: Many changes, including the added `EnableDebugger'
463 config option which lets you debug your Perl plugins more easily.
464 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
465 be more thread-safe otherwise by locking calls to the library.
466 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
467 correct the values returned by SNMP-agents. If a <data> block is
468 defined as `table' the instance is now optional. The sequence number
469 is used as the type-instance in this case. The new `InstancePrefix'
470 option allows to add arbitrary prefixes to the type-instance.
471 * tcpconns plugin: The new `tcpconns' plugin collects the number of
472 certain TCP connections and what state they're in. This can be used
473 to see how many connections your FTP server has to handle or how
474 many outgoing connections your mailserver has open.
476 2008-01-11, Version 4.1.6
477 * unixsock plugin: A bug in the unixsock plugin caused it not to set
478 the permission on the socket as documented in the manpage. Thanks to
479 Evgeny Chukreev for fixing this issue.
480 * collectd: The documentation has been improved.
482 2007-12-27, Version 4.1.5
483 * rrdtool plugin: Fix a memory leak that only occurred in very-low-

486 of the libsensors library.
488 2007-11-08, Version 4.1.4
489 * Build system: Improve detection of the rrd library, especially if
490 it's in a non-standard location.
491 * Build system: A bug when parsing the argument for
492 `--with-libnetsnmp' has been fixed.
493 * collectd: Implement `strerror_r' if the libc doesn't provide it.
494 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
495 a deadlock or delay when shutting down the daemon.
496 * snmp plugin: Fix a memory leak.
498 2007-10-24, Version 4.1.3
499 * collectd: A build issue under Solaris has been resolved by renaming
501 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
502 be more thread-safe otherwise by locking calls to the library.
504 2007-09-28, Version 4.1.2
505 * apcups plugin: Fix reporting of the `load percent' data.
506 * wireless plugin: Correct the handling of cards returning signal and
507 noise quality as percentage.

527 whatever the client thinks is `now'..
529 2007-09-01, Version 4.1.0
530 * Build system: The build system has been changed to automatically
531 disable all plugins, which are missing dependencies. The dependency
532 checking has been removed from the plugins themselves to remove
534 * Flexible interval: The interval of collected data is now sent along
535 with the data itself over the network, so that the interval-settings
536 of server and clients no longer needs to match.
537 * netlink plugin: The new `netlink' plugin connects to the Linux
538 kernel using a netlink socket and uses it to query information about
539 interfaces, qdiscs and classes.
540 * rrdtool plugin: The cache is now dumped to disk in an extra thread
541 to not block data collection.
542 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
543 network devices, such as switches, routers, thermometers, rack
544 monitoring servers, etc. The collectd-snmp(5) manpage documents this
546 * unixsock plugin: Added the `LISTVAL' command.
547 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
548 of music played with xmms.

558 with the broken GNU version of `strerror_r'.
559 * collectd: Write an error message to STDERR when loading of a plugin
561 * apcups plugin: Fix the `types' used to submit the values: They still
562 has an `apcups_' prefix which doesn't work anymore.
563 * rrdtool plugin: Create new RRD-files with the `begin' time set to
564 whatever the client thinks is `now'..
566 2007-08-26, Version 4.0.7
567 * documentation: Some typos have been fixed and some information has
569 * build system: Many fixes for detecting libraries in unusual places,
570 such as on RedHat systems. The affected libraries are `libcurl',
571 `libmysql', and `libupsclient'.
572 * network plugin: Allow the `Port' option to be specified as a number
573 (i. e. without quotes).
574 * nut plugin: A fix allows linking the nut plugin against
575 libupsclient, version >= 2.2.0.
576 * processes plugin: Fix a potential segmentation fault.
578 2007-07-30, Version 4.0.6
579 * sensors plugin: Fix the ignorelist functionality: Only the `type
580 instance' was used to match against the list, but the documentation
581 told otherwise. This release fixes the code, so it complies with the
583 * syslog plugin: Call `openlog' right when the plugin is loaded, so
584 configuration messages will end up in the logging facility.
585 * conrtib/fedora: The contributed specfile for Fedora has been
588 2007-07-05, Version 4.0.5
589 * Portability: More fixes for OpenBSD have been included.

608 they're given in numerically form.
610 2007-06-07, Version 4.0.1
611 * iptables plugin: A bug in the configuration routine has been fixed.
612 Setting a comment in the configfile will no longer cause a
615 2007-06-03, Version 4.0.0
616 * collectd: The plugin-infrastructure has been changed to allow for
617 more types of plugins, namely `write' and `log' plugins.
618 * collectd: The read-function has been changed to read many plugins in
619 parallel, using threads. Thus, plugins generally need to use
620 thread-safe functions from now on.
621 * collectd: The '-t' command line options allows to perform syntax tests
622 of the configuration file and exit immediately.
623 * csv plugin: The new `csv' plugin handles output to `comma separated
625 * rrdtool plugin: The new `rrdtool' plugin handles output to
626 RRD-files. Data can be cached to combine multiple updates into one
627 write to increase IO-performance.
628 * network plugin: The new `network' plugin handles IO via the network.
629 It implements a different, much more extensible protocol which can
630 combine many values in one packet, decreasing the number of UDP-
631 packets being sent. It can read from and send to the network and
632 with the appropriate configuration even forward packets to other
634 * unixsock plugin: The new `unixsock' plugin provides an interface to
635 communicate with the daemon while it is running. Right now the
636 commands `GETVAL' and `PUTVAL' are implemented, but more are to
638 * perl plugin: The new `perl' plugin allows you to write extensions
639 for collectd in the scripting-language Perl.
640 * logfile plugin: The new `logfile' plugin writes logmessages to files
642 * syslog plugin: The new `syslog' plugin sends logmessages to the

645 entropy currently being available to the system.
646 * exec plugin: The new `exec' plugin forks child processes and reads
647 back values provided by the forked processes.
648 * iptables plugin: The new `iptables' plugin reads counters from
649 iptables rules. Thanks to Sjoerd van der Berg for contributing this
651 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
652 to Peter Holik for contributing this plugin.
653 * nut plugin: The new `nut' plugin connects the upsd of the `network
654 ups tools' and reads information about the connected UPS.
655 * apache plugin: Support for lighttpd's `BusyServers' (aka.
656 connections) field was added by Florent Monbillard.
657 * collectd-nagios: The new `collectd-nagios' binary queries values
658 from collectd, parses them and exits according to Nagios-standards.
659 * manpages: The manpages have been improved a lot.
661 2007-09-28, Version 3.11.7
662 * wireless plugin: Correct the handling of cards returning signal and
663 noise quality as percentage.
665 2007-08-31, Version 3.11.6

669 * configure: Added `AC_SYS_LARGEFILE' for LFS.
670 * ntpd plugin: Fix a potential buffer overflow.
671 * processes plugin: Fix a bug when run under Linux 2.4. All processes
672 were accounted as `zombies'.
674 2007-04-10, Version 3.11.4
675 * dns plugin: Change the order of includes to make the plugin compile
678 2007-03-30, Version 3.11.3
679 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
680 of the unused `COLLECT_KSTAT'.
682 2007-02-11, Version 3.11.2
683 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
684 NULL-pointer may have been passed to `printf' which causes a
685 segfault with some libcs.
687 2007-02-10, Version 3.11.1
688 * df plugin: Some wrong defines have been fixed so the plugin works
690 * dns plugin: The usage of a struct has been fixed to work with
692 * processes plugin: Some missing defines have been added so the plugin
693 compiles cleanly under FreeBSD and presumably other UNIXes.
695 2006-12-22, Version 3.11.0
696 * collectd: The new command line option `-P' makes it easier for
697 distributors to change the location of PID-files.
698 * collectd: The daemon shuts down faster now which makes it easier to
699 write init.d-scripts for it.
700 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
701 caused problems every now and then.
702 * df plugin: New config options allow to ignore certain mountpoints,
703 filesystem types or devices.
704 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
705 and interprets it. It collects traffic as well as qtype, opcode and
707 * email plugin: Sebastian Harl has contributed this plugin which
708 counts received mails in categories (e. g. ham, spam, virus), spam
709 score (as given by SpamAssassin) and check types.
710 * mbmon plugin: Flavio Stanchina has contributed this plugin which
711 uses `mbmon' to gather information from sensors on the motherboard.
712 * processes plugin: Collect detailed statistics for configured
713 processes, that's process and thread count, CPU usage, resident
714 segment size and pagefaults.
715 * multimeter plugin: Peter Holik contributed a new plugin which
717 * sensors plugin: Lubos Stanek has put much effort into improving this
718 plugin, including `extended naming', collection of voltage values
719 and the possibility to ignore certain values.
721 2006-12-21, Version 3.10.4
722 * Max Kellermann has identified a bug in the server routine: When
723 opening a socket fails the daemon will (re)try opening the socket in
724 an endless loop, ultimately leading to a `EMFILE' error.
726 2006-11-04, Version 3.10.3
727 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
728 ntpd's reply was sent in more than one packet, the buffer size was
729 calculated incorrectly, resulting in the reading of uninitialized or
732 2006-11-01, Version 3.10.2
733 * The sample config file has been improved.
734 * Errors in the manpages have been corrected.
735 * The ping-plugin now adds hosts during initialization, not during
736 startup. This speeds up startup when no network connectivity is
737 available. Also, the hosts are being added later when the network is
739 * Improved BSD-support for the df-plugin.
740 * Fixed syntax errors in the swap-plugin for Mac OS X.
741 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
743 * Don't disable the mysql-plugin if connecting to the database fails
744 during initialization. Instead, try again in increasing intervals.
746 2006-07-19, Version 3.10.1
747 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
748 the apcups cannot be reached, unconnected sockets will pile up and
749 eventually lead to `Too many open files' errors.
751 2006-07-09, Version 3.10.0
752 * The `disk' plugin has been ported to Darwin.
753 * The `battery' plugin should work on many Apple computers now.
754 * The `traffic' plugin can now ignore certain interfaces. Also,
755 statistics for sent/received packets and errors have been added.
756 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
757 to Anthony Gialluca for contributing this plugin and providing me
758 with a test environment :)
759 * A plugin for monitoring an NTP instance and the local clock drift
762 2006-06-25, Version 3.9.4
763 * The Solaris code in the `swap' plugin has been changed to reflect
764 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
766 * The debugging system has been fixed to work with the Sun libc.
767 * When built without librrd the variable `operating_mode' could be
768 uninitialized. Thanks to David Elliot for reporting the bug.
770 2006-06-01, Version 3.9.3
771 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
772 operating systems also profit from the changes, but I wasn't able to
774 * Changed the build system to find the netinet-includes under FreeBSD
775 and therefore successfully build the `liboping' library there.
777 2006-05-09, Version 3.9.2
778 * Applied a patch to the `liboping' library. Due to a bug in the
779 sequence checking the `ping' plugin stopped working after
780 approximately 7.6 days.
782 2006-05-09, Version 3.8.5
783 * Applied a patch to the `liboping' library. Due to a bug in the
784 sequence checking the `ping' plugin stopped working after
785 approximately 7.6 days.
787 2006-04-21, Version 3.9.1
788 * Build issues with Solaris and possible other architectures have been
790 * Problems when building the `apache'-plugin without `libcurl' have
792 * A bug in the `ping' plugin has been fixed. Sorry folks.
794 2006-04-02, Version 3.9.0
795 * A plugin to monitor the Apache webserver has been added.
796 <http://httpd.apache.org/>
797 * A plugin to collect statistics about virtual servers using VServer.
798 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

801 strength, link quality and noise ratio..
802 * A plugin for Apple hardware sensors has been added.
803 * An option to compile collectd with different `step' and `heartbeat'
804 settings has been added. The size of RRAs is no longer static but
805 calculated based on the settings for `step' and `width'.
806 * The `ping' plugin can now be configured to use a certain TTL.
807 * A plugin to monitor the hardware sensors of Apple computers has been
809 * The plugins `cpu', `memory', `processes' and `traffic' have been
810 ported to Mach/Darwin (Mac OS X).
811 * The `log mode' has been contributed by Christophe Kalt. It writes
812 the data into text files rather than RRD files.
814 2006-04-09, Version 3.8.4
815 * Applied patch by Vincent Stehlé which improves the disk-name
816 resolution in the `hddtemp' plugin for Linux systems.
818 2006-04-02, Version 3.8.3
819 * Applied a patch by James Byers: The MySQL plugin was not working
820 with MySQL 5.0.2 or later.
822 2006-03-14, Version 3.8.2
823 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
824 the GNU libc, because it points to `/etc/fstab' rather than
827 2006-03-13, Version 3.8.1
828 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
829 * Fixes in the debian `postinst' and `init.d' scripts.
831 2006-03-09, Version 3.8.0
832 * The `ping' plugin no longer uses `libping' but a self written
833 library named `liboping'. With this library it's possible to ping
834 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
836 2006-02-18, Version 3.7.2
837 * A simple bug in the `battery' plugin has been fixed. It should now
838 work with ACPI based batteries as well. Thanks to Sebastian for
840 * Fixing a bug that prevented collectd to be built without librrd.
841 Thanks to Werner Heuser for reporting it.
843 2006-02-04, Version 3.7.1
844 * The new network code has been improved to build with older versions
846 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks

849 2006-01-30, Version 3.7.0
850 * The `battery' plugin has been added. It collects information about
852 * The MySQL plugin has been improved: It now writes two more RRD
853 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
854 * The `cpufreq' plugin now reads another file since the file it did
855 read so far causes much overhead in the kernel. Also, you need root
856 to read the old file, but not to read the new one.
857 * The `hddtemp' plugin can now be configured to connect to another
858 address and/or port than localhost.
859 * The `df' plugin now prefers `statvfs' over `statfs'.
860 * The network code has been rewritten. collectd now supports unicast
861 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
862 be set in the configfile.
864 2006-01-24, Version 3.6.2
865 * Due to a bug in the configfile handling collectd wouldn't start in
866 client mode. This released fixes this.
868 2006-01-20, Version 3.6.1
869 * Due to a bug in `configure.in' all modules and the binary were
870 linked against `libmysqlclient'. This issue is solved by this
873 2006-01-17, Version 3.6.0
874 * A config file has been added. This allows for loading only specific
876 * A `df' plugin has been added.
877 * A `mysql' plugin has been added.
878 * The `ping' plugin doesn't entirely give up hope when a socket error
879 occurred, but will back of and increase the intervals between tries.
881 2006-01-21, Version 3.5.2
882 * Fixed yet another bug in the signal handling.. Stupid typo..
883 * Improved the ping plugin to not give up on socket errors (backport
886 2005-12-18, Version 3.5.1
887 * The PID-file is now deleted correctly when shutting down the daemon.
888 * SIGINT and SIGTERM are now handled correctly.
890 2005-12-16, Version 3.5.0 (Revision 326)
891 * A bug in the `load' module under Solaris has been fixed.
892 * The `users' module has been contributed by Sebastian Harl. It counts
893 currently logged in users.
894 * The CPU module now works under FreeBSD without the use of
895 `libstatgrab', however SMP support is missing.
896 * The default directories for the RRD files and the PID file now
897 depend on the compile time setting of `localstatedir'.
899 2005-11-15, Version 3.4.0 (Revision 236)
900 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
901 from gentoo's bugzilla for writing the patch.
902 * The build dependency for librrd has been removed. Binaries built
903 without librrd are client-only and will multicast their value as
904 with the `-c' argument.
905 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
906 * The newly introduced `-f' switch prevents daemon initialization
907 (forking, closing standard filehandles, etc.) Thanks to Alvaro
908 Barcellos for this patch.
910 2005-11-04, Version 3.3.0 (Revision 216)
911 * New modules have been added:
912 - `serial', for monitoring traffic on the serial interfaces
913 - `nfs', for graphing NFS procedure calls
914 - `tape', traffic from/to tape devices

925 2005-10-16, Version 3.1.0 (Revision 194)
926 * Added the `setsid' syscall to the startup code.
927 * Support for hddtemp has been added (thanks to Vincent Stehlé)
929 2005-09-30, Version 3.0.0 (Revision 184)
930 * The ability to send/receive data to/from the network (think
931 multicast) has been added.
932 * Modules have been split up into shared libraries can be loaded at
933 runtime. The biggest advantage is that the core program doesn't need
934 to be linked against an external library.
935 * A patch by George Kargiotakis has been applied: It fixes the sensors
936 behaviour then more than one sensor is being queried.
938 2005-09-16, Version 2.1.0 (Revision 172)
939 * A module for swap statistics has been added.
941 2005-09-09, Version 2.0.0 (Revision 135)
942 * Filenames can no longer be configured at program startup. The only
943 options as of this version are the directory and ping hosts.
944 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
945 Soft-IRQ statistics are added to `System'.
946 * Diskstats now collect read and write bytes, not sectors.
947 * Ping statistics can now be collected for more than one host. There
948 is no default any more: If no host is given no host will be pinged.
949 * A self-written patch for libping has been applied so it builds
952 2005-09-01, Version 1.8.1 (Revision 123)
953 * Much improved configure-script: libraries and features may now be
955 * More detailed warnings/error messages when RRD update fails.
957 2005-08-29, Version 1.8.0:
958 * Support for collecting disk statistics under Solaris.
960 2005-08-25, Version 1.7.0:
961 * Support for libstatgrab[1] for load, memory usage and network
962 traffic. CPU- and disk-usage are not (yet) supported, since
963 libstatgrab returns insufficient information. I will contact the
965 * Improved the CPU-initialization code for Solaris. Apparently CPUs
966 aren't necessarily counted linear which is now handled correctly.
967 [1]: http://www.i-scream.org/libstatgrab/
969 2005-08-21, Version 1.6.0:
970 * Basic support for Solaris: System load and cpu-usage can be
971 collected under Solaris, too. Other stats will follow later.
972 * Many fixes in the autoconf-script
973 * Collection/Museum scripts have been added under contrib/museum
974 * collectd may now be started in unprivileged mode, though ping
975 statistics will not work.
977 2005-07-17, Version 1.5.1:
978 * Diskstats-RRDs now use major/minor for naming. Some systems have
979 weird strings as disk-names..
981 2005-07-17, Version 1.5:
982 * A new module, diskstats, has been added. It collects information
983 about the disks and partitions.
985 2005-07-11, Version 1.4.2:
986 * The meminfo module has been changed to work with more platforms
987 and/or kernel versions.
989 2005-07-10, Version 1.4.1: Correct traffic stats
990 * The traffic rrd-file is now created with DS-type `COUNTER' which I
991 forgot to correct when I changed that module.
993 2005-07-09, Version 1.4: More traffic stats
994 * Traffic is now collected for all interfaces that can be found
995 * Temperature-statistics are read from lm-sensors if available
997 2005-07-08, Version 1.3: CPU stats
998 * Collecting CPU statistics now
1000 2004-07-12, Version 1.2: Using syslog
1001 * collectd is now using the syslog facility to report errors, warnings
1003 * The default directory is now /var/db/collectd
1005 2004-07-10, Version 1.1: Minor changes
1006 * Nothing really useful to say ;)
1008 2004-07-09, Version 1.0: Initial Version
1009 * The following modules are provided:
projects / collectd.git / blob
