1 2009-12-18, Version 4.7.5
2 * Build system, java plugin: Don't use “find -L” to search for Java
3 headers, because it's a GNU extension.
4 * Build system: Support for parallel builds has been improved. Thanks
5 Sebastian Harl and Stefan Völkel for looking into this.
6 * collectd: Print error messages to STDERR if no log plugin has been
7 loaded.
8 * memory plugin: Handling of >4 Gbyte of memory has been fixed.
9 * network plugin: The license has been changed to LGPL 2.1.
10 * oracle plugin: Reconnect to the database if the connection dies.
11 * rrdcached plugin: Work-around for a bug in RRDtool 1.4rc2 has been
12 added.
13 * snmp plugin: Handling of negative values has been fixed. Strings
14 containing control characters are now interpreted as hex-strings.
15 * unixsock plugin: A memory leak in the LISTVAL command has been
16 fixed. Thanks to Ben Knight for his patch.
18 2009-10-03, Version 4.7.4
19 * Build system: Issues when building the iptables plugin have been
20 fixed.
21 * exec plugin: Clear the signal block mask before calling exec(2).
22 * perl plugin: Declare the “environ” variable. This solves build
23 issues on some platforms.
24 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
25 Andrés J. Díaz for the patch.
26 * unixsock plugin: Fix a (well hidden) race condition related to file
27 descriptor handling.
29 2009-09-13, Version 4.7.3
30 * collectd: Fix a possible but very rare invalid “free” in the caching
31 code. Thanks to Sebastian Harl for the patch.
32 * collectd: Remove old values when a cache entry is marked as missing.
33 This way the “GETVAL” command of the UnixSock plugin doesn't return
34 old, no longer valid values when this happens. Thanks to Andrés J.
35 Díaz for the patch.
36 * collectd: The “plugin_unregister_read” function has been fixed.
37 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
38 to follow redirects. Thanks to Joey Hess for reporting this bug.

40 possibly reducing the number of stats considerably. Thanks to Joey
41 Hess for reporting this bug.
42 * iptables plugin: Support for the new libiptc API has been added.
43 Thanks to Sebastian Harl for the patch. The build system has been
44 updated to the plugin only includes the shipped header files when it
45 is linked with the shipped library, too.
46 * java plugin: Delay creating the JVM until after the daemon has
47 forked. The JVM internally creates threads that are lost when
48 forking. This means that Java-based plugins are now configured
49 during the init-phase, i. e. later than other plugins.
50 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
51 to Alan Pevec for the patch.
52 * network plugin: Fix the handling of the “CacheFlush” option: The
53 value was assigned to a wrong variable. The initialization of the
54 gcrypt library, which is used for signing / encrypting traffic, has
55 been fixed. Thanks to Luke Heberling for the patch.
56 * powerdns plugin: Set a timeout when reading data from the datagram
57 socket. Handling of the “LocalSocket” option has been fixed. An
58 incorrectly used “type” has been corrected. Thanks to Luke Heberling
59 for his patches.

72 2009-06-02, Version 4.7.1
73 * Build system: Detection of Java has been improved and missing
74 details have been added to the configuration summary. Support for
75 libtool 2.2 has been added.
76 * collectd: Two bugs with the threshold checking have been fixed. The
77 first one prevented thresholds to be checked at all, the second one
78 caused wrong behavior with the persistency option. Thanks to Andrés
79 J. Díaz for fixing these problems.
80 * collectd: Handling of the `Include' configuration option has been
81 fixed.
82 * rrdtool plugin: Make sure initialization is run only once. This
83 resolves problems under Solaris and potentially other systems.
84 Thanks to Amit Gupta for reporting this bug.
85 * java plugin: Make it possible to use dots ('.') instead of slashes
86 ('/') as the class separator. Thanks to Randy Rizun for pointing
87 this out.

100 Konetzko for the patch.
101 * gmond plugin: The new gmond plugin can receive and interpret
102 multicast traffic from Ganglia's gmond daemon.
103 * java plugin: The new java plugin exports the collectd API to Java,
104 making it possible to write extensions to collectd in Java.
105 * memcachec plugin: The new memcachec plugin queries data from a
106 memcached daemon and parses it similar to the cURL plugin. Thanks to
107 Doug MacEachern for the initial code.
108 * memcached plugin: Support for connections over UNIX domain sockets
109 has been added. Thanks to Franck Lombardi for the patch.
110 * memory plugin: Support for OpenBSD and possibly other *BSDs has been

124 structured files, such as many files beneath /proc.
125 * ted plugin: The new TED plugin reads power consumption measurements
126 from “The Energy Detective” (TED). Thanks to Eric Reed for this
127 plugin.
128 * onewire plugin: The new `Interval' option allows collecting
129 information from OneWire sensors at arbitrary intervals.
130 * ping plugin: Support for collecting the drop rate and standard
131 deviation of round-trip times has been added.
132 * uptime plugin: The new uptime plugin can collect the server's
133 uptime. Thanks to Marco Chiappero for the patch.
135 2009-09-10, Version 4.6.5
136 * collectd: Remove old values when a cache entry is marked as missing.
137 This way the “GETVAL” command of the UnixSock plugin doesn't return
138 old, no longer valid values when this happens. Thanks to Andrés J.
139 Díaz for the patch.
140 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
141 to follow redirects. Thanks to Joey Hess for reporting this bug.

164 2009-06-02, Version 4.6.3
165 * Build system, various plugins: Many build fixes for FreeBSD,
166 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
167 for many fixes and providing a build system for many platforms,
168 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
169 providing an OpenBSD system.
170 * collectd: Two bugs with the threshold checking have been fixed. The
171 first one prevented thresholds to be checked at all, the second one
172 caused wrong behavior with the persistency option. Thanks to Andrés
173 J. Díaz for fixing these problems.
174 * collectd: Handling of the `Include' configuration option has been
175 fixed.
176 * battery plugin: Don't complain about a missing directory every
177 interval.
178 * exec plugin: Allow executed programs to close STDERR. Thanks to
179 Thorsten von Eicken for reporting this problem.
180 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to

190 * filter subsystem: Allow `Chains' without default targets.
191 * liboping: A patch to comply with strict aliasing rules has been
192 added.
193 * timediff match: Fix a typo: The match was registered with a wrong
194 name which prevented this match to be used as documented. Thanks to
195 Bruno Prémont for finding this problem.
196 * bind plugin: Fix collection of the cached RR sets. The number of RR
197 sets currently in the cache was collected as a counter value, which
198 is nonsense. Thanks to Bruno Prémont for implementing this.
199 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
200 primarily BSDs, don't take it well and crash.
201 * oracle plugin: Portability to 64 bit systems has been improved.
202 * postgresql plugin: The default configuration has been improved.
203 * rrdtool plugin: Fix a possible race condition: If the network plugin
204 is brought and dispatches a value before the rrdtool plugin is
205 initialized, the daemon may crash.
207 2009-02-22, Version 4.6.1
208 * collectd: Many documentation fixes.
209 * Collectd::Unixsock: Error handling has been improved.

214 faults. Thanks to Peter Holik for his patch.
216 2009-02-16, Version 4.6.0
217 * collectd: Added the `filter chain' infrastructure, which allows the
218 user to use `matches' and `targets' to control value processing.
219 * collectd: The new `-T' command line argument allows more in-depth
220 testing of a configuration. Thanks to Doug MacEachern for the patch.
221 * collectd-nagios: The Nagios integration command has been updated to
222 use libcollectdclient. The `percentage' aggregation function has
223 been added. Thanks to Fabian Linzberger for the patch.
224 * libcollectdclient: A library which abstracts communication with the
225 unixsock plugin for clients has been added.
226 * regex match: Match values by their identifies using regular
227 expressions.
228 * timediff match: Match for values with an invalid timestamp.
229 * value match: Select values by their data sources' values.
230 * notification target: Create and dispatch a notification.
231 * replace target: Replace parts of an identifier using regular
232 expressions.
233 * set target: Set (overwrite) entire parts of an identifier.
234 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
235 statistics, allowing very detailed name server statistics. Thanks to
236 Bruno Prémont for this plugin.
237 * cpu plugin: Report `interrupt' separately when using
238 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
239 example for native OpenBSD support, has been added. Thanks to Simon
240 Kuhnle for the patch.
241 * csv plugin: Make it possible to write values to STDOUT instead of
242 files. This is meant for testing purposes mostly. The output written
243 to STDOUT is compatible with the exec plugin. Thanks to Doug
244 MacEachern for the patch.
245 * curl plugin: This new plugin can be used to read web pages and parse
246 them using the same mechanism that's used in the tail plugin.
247 * dbi plugin: This new plugin allows you to connect to a variety of
248 relational databases and use SQL to gather custom statistics from
249 it. It is similar to the already existing PostgreSQL plugin but uses
250 libdbi to communicate with the database(s).
251 * interface plugin: Use the ignorelist framework when selecting /
252 ignoring interfaces. This allows one to use regular expressions to
253 select interfaces, too.
254 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
255 Thanks to Bruno Prémont for this patch.
256 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
257 for the patch.
258 * mysql plugin: Allow connecting to a database via the UNIX domain
259 socket, too. Thanks to Mirko Buffoni for the patch.

263 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
264 * oracle plugin: This new plugin allows you to connect to an Oracle
265 database and use SQL to gather custom statistics from it. It is
266 similar to the already existing PostgreSQL plugin.
267 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
268 have been added.
269 * perl plugin: Export the newly added plugin_write() to Perl plugins.
270 * perl plugin: Added support for `notification meta data'.
271 * perl plugin: Added support for the `filter chain' infrastructure by
272 allowing plugins to register `matches' and `targets'.
273 * postgresql plugin: The preferred configuration syntax has been
274 updated to be in line with the syntax used by the new dbi and oracle
275 plugins. The compatibility code for the old syntax is present.
276 Support for the new `Result' blocks and the interval parameter has
277 been added.
278 * processes plugin: Stacksize and virtual memory usage statistics have
279 been added. Portability fixes.
280 * rrdcached plugin: This new plugin uses the (still in development)
281 RRD accelerator daemon, rrdcached. This daemon works very similar to
282 the original rrdtool plugin of collectd, but adds some more nice
283 features.
284 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
285 added.
287 2009-05-09, Version 4.5.4
288 * Build system, various plugins: Many build fixes for FreeBSD,
289 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
290 for many fixes and providing a build system for many platforms,
291 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
292 providing an OpenBSD system.
293 * collectd: Fix a potential race condition when creating directories.
294 * battery plugin: Don't complain about a missing directory every
295 interval.
296 * dns plugin: Slight portability fixes.
297 * exec plugin: Allow executed programs to close STDERR. Thanks to
298 Thorsten von Eicken for reporting this problem.
299 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
300 Tomasz Pala for the patch.
301 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
302 the patch.
303 * rrdtool plugin: Fix a possible race condition: If the network plugin
304 is initialized and dispatches a value before the rrdtool plugin is
305 initialized, the daemon may crash.
306 * memory plugin: Fix a potential problem under Solaris.
308 2009-02-22, Version 4.5.3
309 * build system: The check for libupsclient even when `pkg-config' is
310 not available.
311 * collectd: Fix error handling in the global cache.
312 * Collectd::Unixsock: Error handling has been improved.
313 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
314 patch.

316 faults. Thanks to Peter Holik for his patch.
317 * tcpconns plugin: An endianness problem has been fixed in the *BSD
318 code. Thanks to "thated" for reporting this.
320 2009-01-02, Version 4.5.2
321 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
322 file may be in both locations, especially when the database was
323 installed in a non-standard path. Thanks to Dusty Doris for
324 reporting this.
325 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
326 Solaris, in the configure script automatically.
327 * build system, tcpconns plugin: Check for `kvm_nlist' and
328 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
329 library with similar functions to the BSD variant, but doesn't
330 provide these necessary functions.
331 * collectd.conf(5): Various fixes and clarifications.
332 * collectd: Remove a GNUism (unnamed unions), thus improving
333 portability.
334 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
335 This solves portability problems, especially for Solaris.
336 * dns plugin: Fix a portability problem with NetBSD.
337 * filecount plugin: Fix an off-by-one error. This error may cause a
338 segmentation fault.
339 * network plugin: Fix the handling of `type' in the network protocol.
340 Due to a programming mistake, only 4 or 8 bytes would be copied to a
341 much larger buffer. This caused the `type' to be transferred much
342 more often than necessary. In some cases, e. g. the `cpu' and
343 `cpufreq' plugins being used at the same time, data may be corrupted
344 in those files. Thanks to Bruno Prémont for debugging and reporting
345 this issue.
346 * processes plugin: Fix a possible segmentation fault when specifying
347 invalid configuration options.
348 * unixsock plugin: Make sure the initialization function is run only
349 once. This resolves a file descriptor leak under systems which run
350 the initialization more than once, such as Solaris.
352 2008-10-16, Version 4.5.1
353 * build system: Change `--enable-<plugin>' to abort with an error if
354 dependencies are not met. Thanks to Bruno Prémont for the patch.
355 Also, the poisoning of various string functions has been restricted
356 to debug builds.
357 * collectd: Fix a memory leak in the global value cache. With every
358 *missing* value a couple of bytes would be leaked. Another memory
359 leak in the configuration handling code has been fixed. Thanks to
360 Niraj Tolia for reporting these issues.
361 * collectd: Fix an off-by-one error in the ignorelist functionality.
362 When using regular expressions, the last character would be missing,
363 possibly matching differently from what one would expect.
364 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
365 problem.
366 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
367 Linzberger for reporting the bug.
368 * iptables plugin: Fix an off-by-one error. If a string was just one
369 character too long, it was truncated instead of reporting an error.
370 * network plugin: Fix a memory leak in the configuration handling
371 code. Thanks to Niraj Tolia for reporting this issue.
372 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
373 * postgresql plugin: Don't reopen connection during reinitialization.
374 This fixes a bug under Solaris and potentially other platforms.
375 Missing calls to `PQclear' have been added, too. This fixes memory
376 leaks. Thanks to ``Admin'' for reporting these bugs.
377 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
378 library.
379 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
380 problems with some `libc's. Thanks to Matthias Lay for reporting the
381 bug.
383 2008-09-04, Version 4.5.0
384 * collectd: Added the ability to flush certain identifiers.
385 * collectd: The concept of `notification meta data' has been
386 introduced.
387 * filecount plugin: The new filecount plugin counts the number of
388 files in a directory and its subdirectories.
389 * ipmi plugin: Sensor names have been changed to ensure unique names.
390 Notifications upon added and removed sensors can now be generated.
391 * notify_desktop plugin: This new plugin sends notifications to the
392 X desktop using the structure defined in the `Desktop Notification
393 Specification'.
394 * notify_email plugin: This new plugin sends out notifications via
395 email, using the `esmtp' library.
396 * onewire plugin: The new experimental(!) onewire plugin reads values,
397 such as temperatures, from sensors connected to the computer via the
398 onewire bus.
399 * perl plugin: Improved synchronized access to internal data structures
400 and fixed a possible dead-lock.
401 * perl plugin: Added the ability to flush certain identifiers and marked
402 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
403 plugin_flush().
404 * perl plugin: Added the ability to configure Perl plugins.
405 * postgresql plugin: The new postgresql plugin collects statistics
406 about or from a PostgreSQL database.
407 * processes plugin: The `ProcessMatch' option has been added.
408 * rrdtool plugin: Implement throttling of the `update queue' to lessen
409 IO load.
410 * tcpconns plugin: This plugin has been ported to OpenBSD.
411 * thermal plugin: The new thermal plugin collects system temperatures
412 using Linux ACPI thermal zone data.
414 2009-01-02, Version 4.4.5
415 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
416 file may be in both locations, especially when the database was
417 installed in a non-standard path. Thanks to Dusty Doris for
418 reporting this.
419 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
420 Solaris, in the configure script automatically.
421 * collectd.conf(5): Various fixes and clarifications.
422 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
423 portability problems, especially for Solaris.
424 * dns plugin: Fix a portability problem with NetBSD.
425 * network plugin: Fix the handling of `type' in the network protocol.
426 Due to a programming mistake, only 4 or 8 bytes would be copied to a
427 much larger buffer. This caused the `type' to be transferred much
428 more often than necessary. In some cases, e. g. the `cpu' and
429 `cpufreq' plugins being used at the same time, data may be corrupted
430 in those files. Thanks to Bruno Prémont for debugging and reporting
431 this issue.
432 * unixsock plugin: Make sure the initialization function is run only
433 once. This resolves a file descriptor leak under systems which run
434 the initialization more than once, such as Solaris.
436 2008-10-16, Version 4.4.4
437 * build system: Change `--enable-<plugin>' to abort with an error if
438 dependencies are not met. Thanks to Bruno Prémont for the patch.
439 Also, the poisoning of various string functions has been restricted
440 to debug builds.
441 * collectd: Fix a memory leak in the global value cache. With every
442 *missing* value a couple of bytes would be leaked. Another memory
443 leak in the configuration handling code has been fixed. Thanks to
444 Niraj Tolia for reporting these issues.
445 * collectd: Fix an off-by-one error in the ignorelist functionality.
446 When using regular expressions, the last character would be missing,
447 possibly matching differently from what one would expect.
448 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
449 problem.
450 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
451 Linzberger for reporting the bug.

453 code. Thanks to Niraj Tolia for reporting this issue.
454 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
455 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
456 problems with some `libc's. Thanks to Matthias Lay for reporting the
457 bug.
459 2008-09-01, Version 4.4.3
460 * collectd: Fix a memory leak in the threshold checking code.

471 of disks.
472 * dns plugin: Fix compilation errors with BIND versions 19991001
473 through 19991005.
474 * network plugin: Bugfix in the init routine: The init function
475 cleared a buffer regardless of its contents. This could lead to lost
476 values under Solaris.
477 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
478 * vserver plugin: Remove usage of the thread-unsafe `readdir'
479 function.

481 returned by some broken drivers.
483 2008-06-03, Version 4.4.1
484 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
485 to kyrone for reporting this.
486 * collectd: Fixed min/max output in notifications generated by
487 threshold checking.
488 * collectd-nagios: Fix the protocol used to communicate with the
489 daemon.
490 * perl plugin: Fail noisily, but don't shutdown the daemon, if
491 initialization has errors. An issue with Perl 5.10 has been fixed.
492 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
493 René Rebe and Siegmund Gorr for reporting this.
495 2008-05-06, Version 4.4.0
496 * collectd: Internal code cleanups.
497 * collectd: Added support for a `Flush' command in the unixsock and
498 exec plugins. This command can be used to force a plugin (or all) to
499 flush its values to disk.
500 * collectd: Thresholds can now be configured to apply to one data
501 source only, making it possible to configure different thresholds
502 for each data source.
503 * apache, nginx plugins: Added the possibility to disable host and/or
504 peer verification.
505 * ascent plugin: The new ascent plugin reads and parses the statistics
506 page of an Ascent server.
507 * cpu plugin: Support for the statgrab library has been added.
508 * disk plugin: The possibility to ignore certain disks or collect only
509 specific disks has been added.

512 sensor values via IPMI, the intelligent platform management
513 interface.
514 * iptables plugin: The iptc library that is used by the iptables
515 plugin has been added to the distribution, because it is not
516 provided by all distributions and removed from at least one.
517 * powerdns plugin: The new powerdns plugin reads statistics from an
518 authoritative or a recursing PowerDNS name server.
519 * rrdtool plugin: The size of the files generated with the default
520 configuration has been decreased.
521 * tail plugin: The new tail plugin can be used to gather statistics by
522 continuously reading from log files.
523 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
524 TeamSpeak2 server and collects statistics about the number of users
525 and number of channels.
526 * users plugin: Support for the statgrab library has been added.
527 * vmem plugin: The new vmem plugin collects very detailed statistics
528 about the virtual memory subsystem of Linux.
530 2008-08-30, Version 4.3.4
531 * Build system: Improved detection of and linking with the statgrab
532 library.
533 * collectd: Portability fixes, especially to determine endianess more
534 reliable.
535 * Various plugins: Fix format strings.
536 * disk plugin: A fix for giving disks under Linux 2.4 the right names
537 again has been applied.
538 * memcached plugin: Fix a too short timeout and a related file
539 descriptor leak.
540 * memory plugin: A typo in the libstatgrab code has been fixed.
541 * network plugin: A fix in the initialization function solves problems
542 under Solaris.

546 added.
548 2008-04-22, Version 4.3.3
549 * build system: Improved detection of several libraries, especially if
550 they are in non-standard paths.
551 * build system: Portability fixes: Automatically define "_REENTRANT"
552 if the libc expects it.
553 * collectd: Error and warning messages have been improved.
554 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
555 using them.
556 * apache plugin: Allocate new memory when reading a webpage instead of
557 using a buffer of static size.
558 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
559 the program.
560 * hddtemp plugin: Error and warning messages have been improved.
561 * sensors plugin: Fix sensor collection for some chip types.
563 2008-03-29, Version 4.3.2
564 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
565 `Persist' threshold options.
566 * collectd: Fix handling of missing values in the global value cache.
567 * collectd: Improved error messages when parsing the configuration.
568 * sensors plugin: Fix temperature collection with libsensors4.
569 * unixsock plugin: Fix mixed input and output operation on streams.
570 * wireless plugin: Fix reading noise value.
572 2008-03-05, Version 4.3.1
573 * exec plugin: Set supplementary group IDs.
574 * network plugin:
575 + Use `memcpy' when constructing/parsing a package to avoid
576 alignment problems on weird architectures, such as Sparc.
577 + Translate doubles to/from the x86 byte representation to ensure
578 cross-platform compatibility.
579 * ping plugin: Correct the handling of the `TTL' setting.
580 * swap plugin: Reapply a patch for Solaris.
581 * tcpconns plugin: Portability improvements.
583 2008-02-18, Version 4.3.0
584 * collectd: Notifications have been added to the daemon. Notifications
585 are status messages that may be associated with a data instance.
586 * collectd: Threshold checking has been added to the daemon. This
587 means that you can configure threshold values for each data
588 instance. If this threshold is exceeded a notification will be
589 created.
590 * collectd: The new `FQDNLookup' option tells the daemon to use the
591 full qualified domain name as the hostname, not just the host part
592 es returned by `gethostname(2)'.
593 * collectd: Support for more than one `TypesDB' file has been added.
594 This is useful when one such file is included in a package but one
595 wants to add custom type definitions.
596 * collectd: The `Include' config option has been expanded to handle
597 entire directories and shell wildcards.
598 * collectdmon: The new `collectdmon' binary detects when collectd
599 terminates and automatically restarts it again.
600 * csv plugin: The CSV plugin is now able to store counter values as a
601 rate, using the `StoreRates' configuration option.
602 * exec plugin: Handling of notifications has been added and the
603 ability to pass arguments to the executed programs has been added.
604 * hddtemp plugin: The new `TranslateDevicename' option lets you
605 disable the translation from device names to major-minor-numbers.
606 * logfile plugin: Handling of notifications has been added.
607 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
608 domain name lookups in this plugin.
609 * perl plugin: Many internal changes added support for handling multiple
610 threads making the plugin reasonably usable inside collectd. The API has
611 been extended to support notifications and export global variables to
612 Perl plugins; callbacks now have to be identified by name rather than a
613 pointer to a subroutine. The plugin is no longer experimental.
614 * uuid plugin: The new UUID plugin sets the hostname to an unique
615 identifier for this host. This is meant for setups where each client
616 may migrate to another physical host, possibly going through one or
617 more name changes in the process. Thanks to Richard Jones from
618 Red Hat's Emerging Technology group for this plugin.
619 * libvirt: The new libvirt plugin uses the `libvirt' library to query
620 CPU, disk and network statistics about guest systems on the same
621 physical server. Thanks to Richard Jones from Red Hat's Emerging
622 Technology group for this plugin.
624 2008-04-22, Version 4.2.7
625 * build system: Improved detection of several libraries, especially if
626 they are in non-standard paths.
627 * build system: Portability fixes: Automatically define "_REENTRANT"
628 if the libc expects it.
629 * collectd: Error and warning messages have been improved.
630 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
631 using them.
632 * apache plugin: Allocate new memory when reading a webpage instead of
633 using a buffer of static size.
634 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
635 the program.
636 * hddtemp plugin: Error and warning messages have been improved.
637 * sensors plugin: Fix sensor collection for some chip types.
639 2008-03-29, Version 4.2.6
640 * collectd: Improved error messages when parsing the configuration.
641 * sensors plugin: Fix temperature collection with libsensors4.
642 * unixsock plugin: Fix mixed input and output operation on streams.
643 * wireless plugin: Fix reading noise value.
645 2008-03-04, Version 4.2.5
646 * apache plugin: Improved initialization and error messages.
647 * exec plugin: Set supplementary group IDs.
648 * network plugin:
649 + Create separate threads for reading from the socket and parsing
650 and dispatching incoming packets. Versions prior to this may have
651 problems in high-load situations, where the socket receive buffers
652 overflows, resulting in gaps in the data.
653 + Use `memcpy' when constructing/parsing a package to avoid
654 alignment problems on weird architectures, such as Sparc.
655 + Translate doubles to/from the x86 byte representation to ensure
656 cross-platform compatibility.
657 * ping plugin: Correct the handling of the `TTL' setting.
658 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
659 * swap plugin: Reapply a patch for Solaris.
660 * tcpconns plugin: Portability improvements.
662 2008-01-21, Version 4.2.4
663 * unixsock plugin: A bug in the unixsock plugin caused it not to set
664 the permission on the socket as documented in the manpage. Thanks to
665 Evgeny Chukreev for fixing this issue.
666 * collectd: The documentation has been improved.
668 2007-12-28, Version 4.2.3
669 * sensors plugin: Updated the plugin to build and work with version 3
670 of the libsensors library.
672 2007-12-15, Version 4.2.2
673 * nginx plugin: Incorrect comparison of strings lead to a segfault
674 when using the plugin. Thanks to Saulius Grigaliunas for fixing
675 this.
676 * logfile plugin: The config option `Timestamp' was handled
677 incorrectly and basically always active. Thanks to Luke Heberling
678 for fixing this.
680 2007-11-08, Version 4.2.1
681 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
682 enabled on the host.
683 * snmp plugin: Fix a memory leak.
685 2007-10-27, Version 4.2.0
686 * collectd: The new config option `Include' lets you include other
687 configfiles and thus split up your config into smaller parts. This
688 may be especially interesting for the snmp plugin to keep the data
689 definitions separate from the host definitions.
690 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
691 (number of connections, octets and packets for each service and
692 destination). Thanks to Sebastian Harl for this plugin.
693 * memcached plugin: The new `memcached' plugin connects to a memcached
694 daemon process and collects statistics of this distributed caching
695 system. Thanks to Antony Dovgal for contributing this plugin.
696 * nginx plugin: The new `nginx' plugin reads the status page of an
697 nginx daemon and saves the handled connections and requests.
698 * perl plugin: Many changes, including the added `EnableDebugger'
699 config option which lets you debug your Perl plugins more easily.
700 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
701 be more thread-safe otherwise by locking calls to the library.
702 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
703 correct the values returned by SNMP-agents. If a <data> block is
704 defined as `table' the instance is now optional. The sequence number
705 is used as the type-instance in this case. The new `InstancePrefix'
706 option allows to add arbitrary prefixes to the type-instance.
707 * tcpconns plugin: The new `tcpconns' plugin collects the number of
708 certain TCP connections and what state they're in. This can be used
709 to see how many connections your FTP server has to handle or how
710 many outgoing connections your mailserver has open.
712 2008-01-11, Version 4.1.6
713 * unixsock plugin: A bug in the unixsock plugin caused it not to set
714 the permission on the socket as documented in the manpage. Thanks to
715 Evgeny Chukreev for fixing this issue.
716 * collectd: The documentation has been improved.
718 2007-12-27, Version 4.1.5
719 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
720 memory situations.
721 * sensors plugin: Updated the plugin to build and work with version 3
722 of the libsensors library.
724 2007-11-08, Version 4.1.4
725 * Build system: Improve detection of the rrd library, especially if
726 it's in a non-standard location.
727 * Build system: A bug when parsing the argument for
728 `--with-libnetsnmp' has been fixed.
729 * collectd: Implement `strerror_r' if the libc doesn't provide it.
730 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
731 a deadlock or delay when shutting down the daemon.
732 * snmp plugin: Fix a memory leak.
734 2007-10-24, Version 4.1.3
735 * collectd: A build issue under Solaris has been resolved by renaming
736 data types.
737 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
738 be more thread-safe otherwise by locking calls to the library.
740 2007-09-28, Version 4.1.2
741 * apcups plugin: Fix reporting of the `load percent' data.
742 * wireless plugin: Correct the handling of cards returning signal and
743 noise quality as percentage.
744 * perl plugin: Fix a possible buffer overflow in get_module_name().
745 * build system: Further improve the detection of libraries.
746 * netlink plugin: Build issues under some older versions of the Linux
747 includes (i. e. Debian Sarge) have been fixed.
748 * snmp plugin: Fix a potential segfault when a host times out. Add
749 support for the `timeticks' type.
751 2007-09-12, Version 4.1.1
752 * Build system: The detection of `libnetlink' has been improved.
753 * collectd: The documentation has been fixed in numerous places.
754 * exec plugin: Setting the group under which to run a program has been
755 fixed.
756 * collectd: The `sstrerror' function was improved to work correctly
757 with the broken GNU version of `strerror_r'.
758 * collectd: Write an error message to STDERR when loading of a plugin
759 fails.
760 * apcups plugin: Fix the `types' used to submit the values: They still
761 has an `apcups_' prefix which doesn't work anymore.
762 * rrdtool plugin: Create new RRD-files with the `begin' time set to
763 whatever the client thinks is `now'..
765 2007-09-01, Version 4.1.0
766 * Build system: The build system has been changed to automatically
767 disable all plugins, which are missing dependencies. The dependency
768 checking has been removed from the plugins themselves to remove
769 redundancy.
770 * Flexible interval: The interval of collected data is now sent along
771 with the data itself over the network, so that the interval-settings
772 of server and clients no longer needs to match.
773 * netlink plugin: The new `netlink' plugin connects to the Linux
774 kernel using a netlink socket and uses it to query information about
775 interfaces, qdiscs and classes.
776 * rrdtool plugin: The cache is now dumped to disk in an extra thread
777 to not block data collection.
778 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
779 network devices, such as switches, routers, thermometers, rack
780 monitoring servers, etc. The collectd-snmp(5) manpage documents this
781 plugin.
782 * unixsock plugin: Added the `LISTVAL' command.
783 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
784 of music played with xmms.
786 2007-09-28, Version 4.0.9
787 * apcups plugin: Fix reporting of the `load percent' data.
788 * wireless plugin: Correct the handling of cards returning signal and
789 noise quality as percentage.
790 * perl plugin: Fix a possible buffer overflow in get_module_name().
792 2007-09-12, Version 4.0.8
793 * collectd: The `sstrerror' function was improved to work correctly
794 with the broken GNU version of `strerror_r'.
795 * collectd: Write an error message to STDERR when loading of a plugin
796 fails.
797 * apcups plugin: Fix the `types' used to submit the values: They still
798 has an `apcups_' prefix which doesn't work anymore.
799 * rrdtool plugin: Create new RRD-files with the `begin' time set to
800 whatever the client thinks is `now'..
802 2007-08-26, Version 4.0.7
803 * documentation: Some typos have been fixed and some information has
804 been improved.
805 * build system: Many fixes for detecting libraries in unusual places,
806 such as on RedHat systems. The affected libraries are `libcurl',
807 `libmysql', and `libupsclient'.
808 * network plugin: Allow the `Port' option to be specified as a number
809 (i. e. without quotes).
810 * nut plugin: A fix allows linking the nut plugin against
811 libupsclient, version >= 2.2.0.
812 * processes plugin: Fix a potential segmentation fault.
814 2007-07-30, Version 4.0.6
815 * sensors plugin: Fix the ignorelist functionality: Only the `type
816 instance' was used to match against the list, but the documentation
817 told otherwise. This release fixes the code, so it complies with the
818 documentation.
819 * syslog plugin: Call `openlog' right when the plugin is loaded, so
820 configuration messages will end up in the logging facility.
821 * conrtib/fedora: The contributed specfile for Fedora has been
822 updated.
824 2007-07-05, Version 4.0.5
825 * Portability: More fixes for OpenBSD have been included.
827 2007-06-24, Version 4.0.4
828 * cpu plugin: Fixed the Solaris code.
829 * dns plugin: Fixed a build issue for OpenBSD.
830 * interface plugin: Fixed the Solaris code.
831 * load plugin: Fixed the alternative `/proc' Linux code.
832 * memory plugin: Fixed the Solaris code.
833 * oconfig: Don't require `-lfl' anymore.
835 2007-06-19, Version 4.0.3
836 * cpu plugin: Fix the Darwin / Mac OS X code.
837 * ping plugin: Use the return value of `getpid', not its address.
838 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
839 initialized correctly.
840 * configure: Added `--with-nan-emulation' to aid cross compilation.
842 2007-06-12, Version 4.0.2
843 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
844 they're given in numerically form.
846 2007-06-07, Version 4.0.1
847 * iptables plugin: A bug in the configuration routine has been fixed.
848 Setting a comment in the configfile will no longer cause a
849 segmentation fault.
851 2007-06-03, Version 4.0.0
852 * collectd: The plugin-infrastructure has been changed to allow for
853 more types of plugins, namely `write' and `log' plugins.
854 * collectd: The read-function has been changed to read many plugins in
855 parallel, using threads. Thus, plugins generally need to use
856 thread-safe functions from now on.
857 * collectd: The '-t' command line options allows to perform syntax tests
858 of the configuration file and exit immediately.
859 * csv plugin: The new `csv' plugin handles output to `comma separated
860 values'-files.
861 * rrdtool plugin: The new `rrdtool' plugin handles output to
862 RRD-files. Data can be cached to combine multiple updates into one
863 write to increase IO-performance.
864 * network plugin: The new `network' plugin handles IO via the network.
865 It implements a different, much more extensible protocol which can
866 combine many values in one packet, decreasing the number of UDP-
867 packets being sent. It can read from and send to the network and
868 with the appropriate configuration even forward packets to other
869 networks.
870 * unixsock plugin: The new `unixsock' plugin provides an interface to
871 communicate with the daemon while it is running. Right now the
872 commands `GETVAL' and `PUTVAL' are implemented, but more are to
873 come.
874 * perl plugin: The new `perl' plugin allows you to write extensions
875 for collectd in the scripting-language Perl.
876 * logfile plugin: The new `logfile' plugin writes logmessages to files
877 or STDOUT or STDERR.
878 * syslog plugin: The new `syslog' plugin sends logmessages to the
879 system's syslog daemon.
880 * entropy plugin: The new `entropy' plugin collects the amount of
881 entropy currently being available to the system.
882 * exec plugin: The new `exec' plugin forks child processes and reads
883 back values provided by the forked processes.
884 * iptables plugin: The new `iptables' plugin reads counters from
885 iptables rules. Thanks to Sjoerd van der Berg for contributing this
886 plugin.
887 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
888 to Peter Holik for contributing this plugin.
889 * nut plugin: The new `nut' plugin connects the upsd of the `network
890 ups tools' and reads information about the connected UPS.
891 * apache plugin: Support for lighttpd's `BusyServers' (aka.
892 connections) field was added by Florent Monbillard.
893 * collectd-nagios: The new `collectd-nagios' binary queries values
894 from collectd, parses them and exits according to Nagios-standards.
895 * manpages: The manpages have been improved a lot.
897 2007-09-28, Version 3.11.7
898 * wireless plugin: Correct the handling of cards returning signal and
899 noise quality as percentage.
901 2007-08-31, Version 3.11.6
902 * processes plugin: Fix a potential segmentation fault.
904 2007-05-29, Version 3.11.5
905 * configure: Added `AC_SYS_LARGEFILE' for LFS.
906 * ntpd plugin: Fix a potential buffer overflow.
907 * processes plugin: Fix a bug when run under Linux 2.4. All processes
908 were accounted as `zombies'.
910 2007-04-10, Version 3.11.4
911 * dns plugin: Change the order of includes to make the plugin compile
912 under FreeBSD.
914 2007-03-30, Version 3.11.3
915 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
916 of the unused `COLLECT_KSTAT'.
918 2007-02-11, Version 3.11.2
919 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
920 NULL-pointer may have been passed to `printf' which causes a
921 segfault with some libcs.
923 2007-02-10, Version 3.11.1
924 * df plugin: Some wrong defines have been fixed so the plugin works
925 under Solaris again.
926 * dns plugin: The usage of a struct has been fixed to work with
927 non-GNU libcs.
928 * processes plugin: Some missing defines have been added so the plugin
929 compiles cleanly under FreeBSD and presumably other UNIXes.
931 2006-12-22, Version 3.11.0
932 * collectd: The new command line option `-P' makes it easier for
933 distributors to change the location of PID-files.
934 * collectd: The daemon shuts down faster now which makes it easier to
935 write init.d-scripts for it.
936 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
937 caused problems every now and then.
938 * df plugin: New config options allow to ignore certain mountpoints,
939 filesystem types or devices.
940 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
941 and interprets it. It collects traffic as well as qtype, opcode and
942 rcode counts.
943 * email plugin: Sebastian Harl has contributed this plugin which
944 counts received mails in categories (e. g. ham, spam, virus), spam
945 score (as given by SpamAssassin) and check types.
946 * mbmon plugin: Flavio Stanchina has contributed this plugin which
947 uses `mbmon' to gather information from sensors on the motherboard.
948 * processes plugin: Collect detailed statistics for configured
949 processes, that's process and thread count, CPU usage, resident
950 segment size and pagefaults.
951 * multimeter plugin: Peter Holik contributed a new plugin which
952 queries multimeters.
953 * sensors plugin: Lubos Stanek has put much effort into improving this
954 plugin, including `extended naming', collection of voltage values
955 and the possibility to ignore certain values.
957 2006-12-21, Version 3.10.4
958 * Max Kellermann has identified a bug in the server routine: When
959 opening a socket fails the daemon will (re)try opening the socket in
960 an endless loop, ultimately leading to a `EMFILE' error.
962 2006-11-04, Version 3.10.3
963 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
964 ntpd's reply was sent in more than one packet, the buffer size was
965 calculated incorrectly, resulting in the reading of uninitialized or
966 freed memory.
968 2006-11-01, Version 3.10.2
969 * The sample config file has been improved.
970 * Errors in the manpages have been corrected.
971 * The ping-plugin now adds hosts during initialization, not during
972 startup. This speeds up startup when no network connectivity is
973 available. Also, the hosts are being added later when the network is
974 available.
975 * Improved BSD-support for the df-plugin.
976 * Fixed syntax errors in the swap-plugin for Mac OS X.
977 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
978 plugin.
979 * Don't disable the mysql-plugin if connecting to the database fails
980 during initialization. Instead, try again in increasing intervals.
982 2006-07-19, Version 3.10.1
983 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
984 the apcups cannot be reached, unconnected sockets will pile up and
985 eventually lead to `Too many open files' errors.
987 2006-07-09, Version 3.10.0
988 * The `disk' plugin has been ported to Darwin.
989 * The `battery' plugin should work on many Apple computers now.
990 * The `traffic' plugin can now ignore certain interfaces. Also,
991 statistics for sent/received packets and errors have been added.
992 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
993 to Anthony Gialluca for contributing this plugin and providing me
994 with a test environment :)
995 * A plugin for monitoring an NTP instance and the local clock drift
996 has been added.
998 2006-06-25, Version 3.9.4
999 * The Solaris code in the `swap' plugin has been changed to reflect
1000 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
1001 working this out.
1002 * The debugging system has been fixed to work with the Sun libc.
1003 * When built without librrd the variable `operating_mode' could be
1004 uninitialized. Thanks to David Elliot for reporting the bug.
1006 2006-06-01, Version 3.9.3
1007 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
1008 operating systems also profit from the changes, but I wasn't able to
1009 check that.
1010 * Changed the build system to find the netinet-includes under FreeBSD
1011 and therefore successfully build the `liboping' library there.
1013 2006-05-09, Version 3.9.2
1014 * Applied a patch to the `liboping' library. Due to a bug in the
1015 sequence checking the `ping' plugin stopped working after
1016 approximately 7.6 days.
1018 2006-05-09, Version 3.8.5
1019 * Applied a patch to the `liboping' library. Due to a bug in the
1020 sequence checking the `ping' plugin stopped working after
1021 approximately 7.6 days.
1023 2006-04-21, Version 3.9.1
1024 * Build issues with Solaris and possible other architectures have been
1025 resolved.
1026 * Problems when building the `apache'-plugin without `libcurl' have
1027 been resolved.
1028 * A bug in the `ping' plugin has been fixed. Sorry folks.
1030 2006-04-02, Version 3.9.0
1031 * A plugin to monitor the Apache webserver has been added.
1032 <http://httpd.apache.org/>
1033 * A plugin to collect statistics about virtual servers using VServer.
1034 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1035 this plugin :)
1036 * A plugin for wireless LAN cards has been added. It monitors signal
1037 strength, link quality and noise ratio..
1038 * A plugin for Apple hardware sensors has been added.
1039 * An option to compile collectd with different `step' and `heartbeat'
1040 settings has been added. The size of RRAs is no longer static but
1041 calculated based on the settings for `step' and `width'.
1042 * The `ping' plugin can now be configured to use a certain TTL.
1043 * A plugin to monitor the hardware sensors of Apple computers has been
1044 added.
1045 * The plugins `cpu', `memory', `processes' and `traffic' have been
1046 ported to Mach/Darwin (Mac OS X).
1047 * The `log mode' has been contributed by Christophe Kalt. It writes
1048 the data into text files rather than RRD files.
1050 2006-04-09, Version 3.8.4
1051 * Applied patch by Vincent Stehlé which improves the disk-name
1052 resolution in the `hddtemp' plugin for Linux systems.
1054 2006-04-02, Version 3.8.3
1055 * Applied a patch by James Byers: The MySQL plugin was not working
1056 with MySQL 5.0.2 or later.
1058 2006-03-14, Version 3.8.2
1059 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1060 the GNU libc, because it points to `/etc/fstab' rather than
1061 `/etc/mtab'.
1063 2006-03-13, Version 3.8.1
1064 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1065 * Fixes in the debian `postinst' and `init.d' scripts.
1067 2006-03-09, Version 3.8.0
1068 * The `ping' plugin no longer uses `libping' but a self written
1069 library named `liboping'. With this library it's possible to ping
1070 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1072 2006-02-18, Version 3.7.2
1073 * A simple bug in the `battery' plugin has been fixed. It should now
1074 work with ACPI based batteries as well. Thanks to Sebastian for
1075 fixing this.
1076 * Fixing a bug that prevented collectd to be built without librrd.
1077 Thanks to Werner Heuser for reporting it.
1079 2006-02-04, Version 3.7.1
1080 * The new network code has been improved to build with older versions
1081 of glibc.
1082 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1083 to Tommie Gannert for this patch.
1085 2006-01-30, Version 3.7.0
1086 * The `battery' plugin has been added. It collects information about
1087 laptop batteries..
1088 * The MySQL plugin has been improved: It now writes two more RRD
1089 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1090 * The `cpufreq' plugin now reads another file since the file it did
1091 read so far causes much overhead in the kernel. Also, you need root
1092 to read the old file, but not to read the new one.
1093 * The `hddtemp' plugin can now be configured to connect to another
1094 address and/or port than localhost.
1095 * The `df' plugin now prefers `statvfs' over `statfs'.
1096 * The network code has been rewritten. collectd now supports unicast
1097 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1098 be set in the configfile.
1100 2006-01-24, Version 3.6.2
1101 * Due to a bug in the configfile handling collectd wouldn't start in
1102 client mode. This released fixes this.
1104 2006-01-20, Version 3.6.1
1105 * Due to a bug in `configure.in' all modules and the binary were
1106 linked against `libmysqlclient'. This issue is solved by this
1107 release.
1109 2006-01-17, Version 3.6.0
1110 * A config file has been added. This allows for loading only specific
1111 plugins.
1112 * A `df' plugin has been added.
1113 * A `mysql' plugin has been added.
1114 * The `ping' plugin doesn't entirely give up hope when a socket error
1115 occurred, but will back of and increase the intervals between tries.
1117 2006-01-21, Version 3.5.2
1118 * Fixed yet another bug in the signal handling.. Stupid typo..
1119 * Improved the ping plugin to not give up on socket errors (backport
1120 from 3.6.0).
1122 2005-12-18, Version 3.5.1
1123 * The PID-file is now deleted correctly when shutting down the daemon.
1124 * SIGINT and SIGTERM are now handled correctly.
1126 2005-12-16, Version 3.5.0 (Revision 326)
1127 * A bug in the `load' module under Solaris has been fixed.
1128 * The `users' module has been contributed by Sebastian Harl. It counts
1129 currently logged in users.
1130 * The CPU module now works under FreeBSD without the use of
1131 `libstatgrab', however SMP support is missing.
1132 * The default directories for the RRD files and the PID file now
1133 depend on the compile time setting of `localstatedir'.
1135 2005-11-15, Version 3.4.0 (Revision 236)
1136 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1137 from gentoo's bugzilla for writing the patch.
1138 * The build dependency for librrd has been removed. Binaries built
1139 without librrd are client-only and will multicast their value as
1140 with the `-c' argument.
1141 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1142 * The newly introduced `-f' switch prevents daemon initialization
1143 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1144 Barcellos for this patch.
1146 2005-11-04, Version 3.3.0 (Revision 216)
1147 * New modules have been added:
1148 - `serial', for monitoring traffic on the serial interfaces
1149 - `nfs', for graphing NFS procedure calls
1150 - `tape', traffic from/to tape devices
1151 * The memory.rrd now accepts more than 4Gig of memory.
1153 2005-10-26, Version 3.2.0 (Revision 200)
1154 * Support for graphing the processes has been added (thanks to Lyonel
1155 Vincent)
1156 * If reading from hddtemp fails collectd will increase the time
1157 between polls up to one day.
1158 * The init.d files have been improved.
1159 * Problems with the spec file have been fixed.
1161 2005-10-16, Version 3.1.0 (Revision 194)
1162 * Added the `setsid' syscall to the startup code.
1163 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1165 2005-09-30, Version 3.0.0 (Revision 184)
1166 * The ability to send/receive data to/from the network (think
1167 multicast) has been added.
1168 * Modules have been split up into shared libraries can be loaded at
1169 runtime. The biggest advantage is that the core program doesn't need
1170 to be linked against an external library.
1171 * A patch by George Kargiotakis has been applied: It fixes the sensors
1172 behaviour then more than one sensor is being queried.
1174 2005-09-16, Version 2.1.0 (Revision 172)
1175 * A module for swap statistics has been added.
1177 2005-09-09, Version 2.0.0 (Revision 135)
1178 * Filenames can no longer be configured at program startup. The only
1179 options as of this version are the directory and ping hosts.
1180 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1181 Soft-IRQ statistics are added to `System'.
1182 * Diskstats now collect read and write bytes, not sectors.
1183 * Ping statistics can now be collected for more than one host. There
1184 is no default any more: If no host is given no host will be pinged.
1185 * A self-written patch for libping has been applied so it builds
1186 cleanly.
1188 2005-09-01, Version 1.8.1 (Revision 123)
1189 * Much improved configure-script: libraries and features may now be
1190 disabled.
1191 * More detailed warnings/error messages when RRD update fails.
1193 2005-08-29, Version 1.8.0:
1194 * Support for collecting disk statistics under Solaris.
1196 2005-08-25, Version 1.7.0:
1197 * Support for libstatgrab[1] for load, memory usage and network
1198 traffic. CPU- and disk-usage are not (yet) supported, since
1199 libstatgrab returns insufficient information. I will contact the
1200 authors.
1201 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1202 aren't necessarily counted linear which is now handled correctly.
1203 [1]: http://www.i-scream.org/libstatgrab/
1205 2005-08-21, Version 1.6.0:
1206 * Basic support for Solaris: System load and cpu-usage can be
1207 collected under Solaris, too. Other stats will follow later.
1208 * Many fixes in the autoconf-script
1209 * Collection/Museum scripts have been added under contrib/museum
1210 * collectd may now be started in unprivileged mode, though ping
1211 statistics will not work.
1213 2005-07-17, Version 1.5.1:
1214 * Diskstats-RRDs now use major/minor for naming. Some systems have
1215 weird strings as disk-names..
1217 2005-07-17, Version 1.5:
1218 * A new module, diskstats, has been added. It collects information
1219 about the disks and partitions.
1221 2005-07-11, Version 1.4.2:
1222 * The meminfo module has been changed to work with more platforms
1223 and/or kernel versions.
1225 2005-07-10, Version 1.4.1: Correct traffic stats
1226 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1227 forgot to correct when I changed that module.
1229 2005-07-09, Version 1.4: More traffic stats
1230 * Traffic is now collected for all interfaces that can be found
1231 * Temperature-statistics are read from lm-sensors if available
1233 2005-07-08, Version 1.3: CPU stats
1234 * Collecting CPU statistics now
1236 2005-07-12, Version 1.2: Using syslog
1237 * collectd is now using the syslog facility to report errors, warnings
1238 and the like..
1239 * The default directory is now /var/db/collectd
1241 2005-07-10, Version 1.1: Minor changes
1242 * Nothing really useful to say ;)
1244 2005-07-09, Version 1.0: Initial Version
1245 * The following modules are provided:
1246 * Load average
1247 * Ping time
1248 * Traffic
1249 * Memory info
