1 2009-10-03, Version 4.7.4
2 * Build system: Issues when building the iptables plugin have been
3 fixed.
4 * exec plugin: Clear the signal block mask before calling exec(2).
5 * perl plugin: Declare the “environ” variable. This solves build
6 issues on some platforms.
7 * processes plugin: Remove unnecessary call of realloc(3). Thanks to
8 Andrés J. Díaz for the patch.
9 * unixsock plugin: Fix a (well hidden) race condition related to file
10 descriptor handling.
12 2009-09-13, Version 4.7.3
13 * collectd: Fix a possible but very rare invalid “free” in the caching
14 code. Thanks to Sebastian Harl for the patch.
15 * collectd: Remove old values when a cache entry is marked as missing.
16 This way the “GETVAL” command of the UnixSock plugin doesn't return
17 old, no longer valid values when this happens. Thanks to Andrés J.
18 Díaz for the patch.
19 * collectd: The “plugin_unregister_read” function has been fixed.
20 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
21 to follow redirects. Thanks to Joey Hess for reporting this bug.
22 * df plugin: Check the ignorelist before stating the file system,
23 possibly reducing the number of stats considerably. Thanks to Joey
24 Hess for reporting this bug.
25 * iptables plugin: Support for the new libiptc API has been added.
26 Thanks to Sebastian Harl for the patch. The build system has been
27 updated to the plugin only includes the shipped header files when it
28 is linked with the shipped library, too.
29 * java plugin: Delay creating the JVM until after the daemon has
30 forked. The JVM internally creates threads that are lost when
31 forking. This means that Java-based plugins are now configured
32 during the init-phase, i. e. later than other plugins.
33 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
34 to Alan Pevec for the patch.
35 * network plugin: Fix the handling of the “CacheFlush” option: The
36 value was assigned to a wrong variable. The initialization of the
37 gcrypt library, which is used for signing / encrypting traffic, has
38 been fixed. Thanks to Luke Heberling for the patch.
39 * powerdns plugin: Set a timeout when reading data from the datagram
40 socket. Handling of the “LocalSocket” option has been fixed. An
41 incorrectly used “type” has been corrected. Thanks to Luke Heberling
42 for his patches.

45 * Build system: Support for `DESTDIR' has been fixed in the Java
46 bindings.
47 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
48 Díaz for fixing this bug.

50 code. The bug may result in an assertion failure.
51 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
52 for reporting the bug.
53 * ping plugin: Link the plugin with libm.
55 2009-06-02, Version 4.7.1
56 * Build system: Detection of Java has been improved and missing
57 details have been added to the configuration summary. Support for
58 libtool 2.2 has been added.
59 * collectd: Two bugs with the threshold checking have been fixed. The
60 first one prevented thresholds to be checked at all, the second one
61 caused wrong behavior with the persistency option. Thanks to Andrés
62 J. Díaz for fixing these problems.
63 * collectd: Handling of the `Include' configuration option has been
64 fixed.
65 * rrdtool plugin: Make sure initialization is run only once. This
66 resolves problems under Solaris and potentially other systems.
67 Thanks to Amit Gupta for reporting this bug.
68 * java plugin: Make it possible to use dots ('.') instead of slashes
69 ('/') as the class separator. Thanks to Randy Rizun for pointing
70 this out.

80 tracking table size. Thanks to Tomasz Pala for the patch.
81 * fscache plugin: The new fscache plugin collects statistics about
82 Linux' file-system based caching framework. Thanks to Edward
83 Konetzko for the patch.
84 * gmond plugin: The new gmond plugin can receive and interpret
85 multicast traffic from Ganglia's gmond daemon.
86 * java plugin: The new java plugin exports the collectd API to Java,
87 making it possible to write extensions to collectd in Java.
88 * memcachec plugin: The new memcachec plugin queries data from a
89 memcached daemon and parses it similar to the cURL plugin. Thanks to
90 Doug MacEachern for the initial code.
91 * memcached plugin: Support for connections over UNIX domain sockets
92 has been added. Thanks to Franck Lombardi for the patch.
93 * memory plugin: Support for OpenBSD and possibly other *BSDs has been
94 added. Thanks to Simon Kuhnle for the patch.

107 structured files, such as many files beneath /proc.
108 * ted plugin: The new TED plugin reads power consumption measurements
109 from “The Energy Detective” (TED). Thanks to Eric Reed for this
110 plugin.
111 * onewire plugin: The new `Interval' option allows collecting
112 information from OneWire sensors at arbitrary intervals.
113 * ping plugin: Support for collecting the drop rate and standard
114 deviation of round-trip times has been added.
115 * uptime plugin: The new uptime plugin can collect the server's
116 uptime. Thanks to Marco Chiappero for the patch.
118 2009-09-10, Version 4.6.5
119 * collectd: Remove old values when a cache entry is marked as missing.
120 This way the “GETVAL” command of the UnixSock plugin doesn't return
121 old, no longer valid values when this happens. Thanks to Andrés J.
122 Díaz for the patch.
123 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
124 to follow redirects. Thanks to Joey Hess for reporting this bug.

140 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
141 Díaz for fixing this bug.
142 * collectd: A programming error has been fixed in the notification
143 code. The bug may result in an assertion failure.
144 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
145 for reporting the bug.
147 2009-06-02, Version 4.6.3
148 * Build system, various plugins: Many build fixes for FreeBSD,
149 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
150 for many fixes and providing a build system for many platforms,
151 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
152 providing an OpenBSD system.
153 * collectd: Two bugs with the threshold checking have been fixed. The
154 first one prevented thresholds to be checked at all, the second one
155 caused wrong behavior with the persistency option. Thanks to Andrés
156 J. Díaz for fixing these problems.
157 * collectd: Handling of the `Include' configuration option has been
158 fixed.
159 * battery plugin: Don't complain about a missing directory every
160 interval.
161 * exec plugin: Allow executed programs to close STDERR. Thanks to
162 Thorsten von Eicken for reporting this problem.
163 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to

173 * filter subsystem: Allow `Chains' without default targets.
174 * liboping: A patch to comply with strict aliasing rules has been
175 added.
176 * timediff match: Fix a typo: The match was registered with a wrong
177 name which prevented this match to be used as documented. Thanks to
178 Bruno Prémont for finding this problem.
179 * bind plugin: Fix collection of the cached RR sets. The number of RR
180 sets currently in the cache was collected as a counter value, which
181 is nonsense. Thanks to Bruno Prémont for implementing this.
182 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
183 primarily BSDs, don't take it well and crash.
184 * oracle plugin: Portability to 64 bit systems has been improved.
185 * postgresql plugin: The default configuration has been improved.
186 * rrdtool plugin: Fix a possible race condition: If the network plugin
187 is brought and dispatches a value before the rrdtool plugin is
188 initialized, the daemon may crash.
190 2009-02-22, Version 4.6.1
191 * collectd: Many documentation fixes.
192 * Collectd::Unixsock: Error handling has been improved.
193 * regex match: Don't link with the PCRE library.
194 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
195 for finding and fixing most of them.

197 faults. Thanks to Peter Holik for his patch.
199 2009-02-16, Version 4.6.0
200 * collectd: Added the `filter chain' infrastructure, which allows the
201 user to use `matches' and `targets' to control value processing.
202 * collectd: The new `-T' command line argument allows more in-depth
203 testing of a configuration. Thanks to Doug MacEachern for the patch.
204 * collectd-nagios: The Nagios integration command has been updated to
205 use libcollectdclient. The `percentage' aggregation function has
206 been added. Thanks to Fabian Linzberger for the patch.
207 * libcollectdclient: A library which abstracts communication with the
208 unixsock plugin for clients has been added.
209 * regex match: Match values by their identifies using regular
210 expressions.
211 * timediff match: Match for values with an invalid timestamp.
212 * value match: Select values by their data sources' values.
213 * notification target: Create and dispatch a notification.
214 * replace target: Replace parts of an identifier using regular
215 expressions.
216 * set target: Set (overwrite) entire parts of an identifier.
217 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
218 statistics, allowing very detailed name server statistics. Thanks to
219 Bruno Prémont for this plugin.
220 * cpu plugin: Report `interrupt' separately when using
221 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
222 example for native OpenBSD support, has been added. Thanks to Simon
223 Kuhnle for the patch.
224 * csv plugin: Make it possible to write values to STDOUT instead of
225 files. This is meant for testing purposes mostly. The output written
226 to STDOUT is compatible with the exec plugin. Thanks to Doug
227 MacEachern for the patch.
228 * curl plugin: This new plugin can be used to read web pages and parse
229 them using the same mechanism that's used in the tail plugin.
230 * dbi plugin: This new plugin allows you to connect to a variety of
231 relational databases and use SQL to gather custom statistics from
232 it. It is similar to the already existing PostgreSQL plugin but uses
233 libdbi to communicate with the database(s).
234 * interface plugin: Use the ignorelist framework when selecting /
235 ignoring interfaces. This allows one to use regular expressions to
236 select interfaces, too.
237 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
238 Thanks to Bruno Prémont for this patch.
239 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
240 for the patch.
241 * mysql plugin: Allow connecting to a database via the UNIX domain
242 socket, too. Thanks to Mirko Buffoni for the patch.

244 code. This hopefully will help very large setups.
245 * openvpn plugin: This new plugin collects statistics provided by the
246 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
247 * oracle plugin: This new plugin allows you to connect to an Oracle
248 database and use SQL to gather custom statistics from it. It is
249 similar to the already existing PostgreSQL plugin.
250 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
251 have been added.
252 * perl plugin: Export the newly added plugin_write() to Perl plugins.
253 * perl plugin: Added support for `notification meta data'.
254 * perl plugin: Added support for the `filter chain' infrastructure by
255 allowing plugins to register `matches' and `targets'.
256 * postgresql plugin: The preferred configuration syntax has been
257 updated to be in line with the syntax used by the new dbi and oracle
258 plugins. The compatibility code for the old syntax is present.
259 Support for the new `Result' blocks and the interval parameter has
260 been added.
261 * processes plugin: Stacksize and virtual memory usage statistics have
262 been added. Portability fixes.
263 * rrdcached plugin: This new plugin uses the (still in development)
264 RRD accelerator daemon, rrdcached. This daemon works very similar to
265 the original rrdtool plugin of collectd, but adds some more nice
266 features.
267 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
268 added.
270 2009-05-09, Version 4.5.4
271 * Build system, various plugins: Many build fixes for FreeBSD,
272 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
273 for many fixes and providing a build system for many platforms,
274 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
275 providing an OpenBSD system.
276 * collectd: Fix a potential race condition when creating directories.
277 * battery plugin: Don't complain about a missing directory every
278 interval.

281 Thorsten von Eicken for reporting this problem.
282 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
283 Tomasz Pala for the patch.
284 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
285 the patch.
286 * rrdtool plugin: Fix a possible race condition: If the network plugin
287 is initialized and dispatches a value before the rrdtool plugin is
288 initialized, the daemon may crash.
289 * memory plugin: Fix a potential problem under Solaris.
291 2009-02-22, Version 4.5.3
292 * build system: The check for libupsclient even when `pkg-config' is
293 not available.
294 * collectd: Fix error handling in the global cache.
295 * Collectd::Unixsock: Error handling has been improved.
296 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his

299 faults. Thanks to Peter Holik for his patch.
300 * tcpconns plugin: An endianness problem has been fixed in the *BSD
301 code. Thanks to "thated" for reporting this.
303 2009-01-02, Version 4.5.2
304 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
305 file may be in both locations, especially when the database was
306 installed in a non-standard path. Thanks to Dusty Doris for
307 reporting this.
308 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
309 Solaris, in the configure script automatically.
310 * build system, tcpconns plugin: Check for `kvm_nlist' and
311 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
312 library with similar functions to the BSD variant, but doesn't
313 provide these necessary functions.
314 * collectd.conf(5): Various fixes and clarifications.
315 * collectd: Remove a GNUism (unnamed unions), thus improving
316 portability.
317 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
318 This solves portability problems, especially for Solaris.
319 * dns plugin: Fix a portability problem with NetBSD.
320 * filecount plugin: Fix an off-by-one error. This error may cause a
321 segmentation fault.
322 * network plugin: Fix the handling of `type' in the network protocol.
323 Due to a programming mistake, only 4 or 8 bytes would be copied to a
324 much larger buffer. This caused the `type' to be transferred much
325 more often than necessary. In some cases, e. g. the `cpu' and
326 `cpufreq' plugins being used at the same time, data may be corrupted
327 in those files. Thanks to Bruno Prémont for debugging and reporting
328 this issue.
329 * processes plugin: Fix a possible segmentation fault when specifying
330 invalid configuration options.
331 * unixsock plugin: Make sure the initialization function is run only
332 once. This resolves a file descriptor leak under systems which run
333 the initialization more than once, such as Solaris.
335 2008-10-16, Version 4.5.1
336 * build system: Change `--enable-<plugin>' to abort with an error if
337 dependencies are not met. Thanks to Bruno Prémont for the patch.
338 Also, the poisoning of various string functions has been restricted
339 to debug builds.
340 * collectd: Fix a memory leak in the global value cache. With every
341 *missing* value a couple of bytes would be leaked. Another memory
342 leak in the configuration handling code has been fixed. Thanks to
343 Niraj Tolia for reporting these issues.
344 * collectd: Fix an off-by-one error in the ignorelist functionality.
345 When using regular expressions, the last character would be missing,
346 possibly matching differently from what one would expect.
347 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
348 problem.
349 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
350 Linzberger for reporting the bug.
351 * iptables plugin: Fix an off-by-one error. If a string was just one
352 character too long, it was truncated instead of reporting an error.
353 * network plugin: Fix a memory leak in the configuration handling
354 code. Thanks to Niraj Tolia for reporting this issue.
355 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
356 * postgresql plugin: Don't reopen connection during reinitialization.
357 This fixes a bug under Solaris and potentially other platforms.
358 Missing calls to `PQclear' have been added, too. This fixes memory
359 leaks. Thanks to ``Admin'' for reporting these bugs.
360 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
361 library.
362 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
363 problems with some `libc's. Thanks to Matthias Lay for reporting the
364 bug.
366 2008-09-04, Version 4.5.0
367 * collectd: Added the ability to flush certain identifiers.
368 * collectd: The concept of `notification meta data' has been
369 introduced.
370 * filecount plugin: The new filecount plugin counts the number of
371 files in a directory and its subdirectories.
372 * ipmi plugin: Sensor names have been changed to ensure unique names.
373 Notifications upon added and removed sensors can now be generated.
374 * notify_desktop plugin: This new plugin sends notifications to the
375 X desktop using the structure defined in the `Desktop Notification
376 Specification'.
377 * notify_email plugin: This new plugin sends out notifications via
378 email, using the `esmtp' library.
379 * onewire plugin: The new experimental(!) onewire plugin reads values,
380 such as temperatures, from sensors connected to the computer via the
381 onewire bus.
382 * perl plugin: Improved synchronized access to internal data structures
383 and fixed a possible dead-lock.
384 * perl plugin: Added the ability to flush certain identifiers and marked
385 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
386 plugin_flush().
387 * perl plugin: Added the ability to configure Perl plugins.
388 * postgresql plugin: The new postgresql plugin collects statistics
389 about or from a PostgreSQL database.
390 * processes plugin: The `ProcessMatch' option has been added.
391 * rrdtool plugin: Implement throttling of the `update queue' to lessen
392 IO load.
393 * tcpconns plugin: This plugin has been ported to OpenBSD.
394 * thermal plugin: The new thermal plugin collects system temperatures
395 using Linux ACPI thermal zone data.
397 2009-01-02, Version 4.4.5
398 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
399 file may be in both locations, especially when the database was
400 installed in a non-standard path. Thanks to Dusty Doris for
401 reporting this.
402 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
403 Solaris, in the configure script automatically.
404 * collectd.conf(5): Various fixes and clarifications.
405 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
406 portability problems, especially for Solaris.
407 * dns plugin: Fix a portability problem with NetBSD.
408 * network plugin: Fix the handling of `type' in the network protocol.
409 Due to a programming mistake, only 4 or 8 bytes would be copied to a
410 much larger buffer. This caused the `type' to be transferred much
411 more often than necessary. In some cases, e. g. the `cpu' and
412 `cpufreq' plugins being used at the same time, data may be corrupted
413 in those files. Thanks to Bruno Prémont for debugging and reporting
414 this issue.
415 * unixsock plugin: Make sure the initialization function is run only
416 once. This resolves a file descriptor leak under systems which run
417 the initialization more than once, such as Solaris.
419 2008-10-16, Version 4.4.4
420 * build system: Change `--enable-<plugin>' to abort with an error if
421 dependencies are not met. Thanks to Bruno Prémont for the patch.
422 Also, the poisoning of various string functions has been restricted
423 to debug builds.
424 * collectd: Fix a memory leak in the global value cache. With every
425 *missing* value a couple of bytes would be leaked. Another memory
426 leak in the configuration handling code has been fixed. Thanks to
427 Niraj Tolia for reporting these issues.
428 * collectd: Fix an off-by-one error in the ignorelist functionality.
429 When using regular expressions, the last character would be missing,
430 possibly matching differently from what one would expect.
431 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
432 problem.
433 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
434 Linzberger for reporting the bug.

436 code. Thanks to Niraj Tolia for reporting this issue.
437 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
438 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
439 problems with some `libc's. Thanks to Matthias Lay for reporting the
440 bug.

454 of disks.
455 * dns plugin: Fix compilation errors with BIND versions 19991001
456 through 19991005.
457 * network plugin: Bugfix in the init routine: The init function
458 cleared a buffer regardless of its contents. This could lead to lost
459 values under Solaris.
460 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
461 * vserver plugin: Remove usage of the thread-unsafe `readdir'
462 function.

464 returned by some broken drivers.
466 2008-06-03, Version 4.4.1
467 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
468 to kyrone for reporting this.

470 threshold checking.
471 * collectd-nagios: Fix the protocol used to communicate with the
472 daemon.
473 * perl plugin: Fail noisily, but don't shutdown the daemon, if
474 initialization has errors. An issue with Perl 5.10 has been fixed.
475 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
476 René Rebe and Siegmund Gorr for reporting this.
478 2008-05-06, Version 4.4.0
479 * collectd: Internal code cleanups.
480 * collectd: Added support for a `Flush' command in the unixsock and
481 exec plugins. This command can be used to force a plugin (or all) to
482 flush its values to disk.
483 * collectd: Thresholds can now be configured to apply to one data
484 source only, making it possible to configure different thresholds
485 for each data source.
486 * apache, nginx plugins: Added the possibility to disable host and/or
487 peer verification.
488 * ascent plugin: The new ascent plugin reads and parses the statistics
489 page of an Ascent server.
490 * cpu plugin: Support for the statgrab library has been added.
491 * disk plugin: The possibility to ignore certain disks or collect only
492 specific disks has been added.
493 * disk plugin: Support for the statgrab library has been added.
494 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
495 sensor values via IPMI, the intelligent platform management
496 interface.
497 * iptables plugin: The iptc library that is used by the iptables
498 plugin has been added to the distribution, because it is not
499 provided by all distributions and removed from at least one.
500 * powerdns plugin: The new powerdns plugin reads statistics from an
501 authoritative or a recursing PowerDNS name server.
502 * rrdtool plugin: The size of the files generated with the default
503 configuration has been decreased.
504 * tail plugin: The new tail plugin can be used to gather statistics by
505 continuously reading from log files.
506 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
507 TeamSpeak2 server and collects statistics about the number of users
508 and number of channels.
509 * users plugin: Support for the statgrab library has been added.
510 * vmem plugin: The new vmem plugin collects very detailed statistics
511 about the virtual memory subsystem of Linux.
513 2008-08-30, Version 4.3.4
514 * Build system: Improved detection of and linking with the statgrab
515 library.
516 * collectd: Portability fixes, especially to determine endianess more
517 reliable.
518 * Various plugins: Fix format strings.
519 * disk plugin: A fix for giving disks under Linux 2.4 the right names
520 again has been applied.
521 * memcached plugin: Fix a too short timeout and a related file
522 descriptor leak.
523 * memory plugin: A typo in the libstatgrab code has been fixed.
524 * network plugin: A fix in the initialization function solves problems
525 under Solaris.
526 * nginx plugin: A thread-unsafe function has been replaced.
527 * vserver plugin: A thread-unsafe function has been replaced.
528 * wireless plugin: A work-around for broken wireless drivers has been
529 added.
531 2008-04-22, Version 4.3.3
532 * build system: Improved detection of several libraries, especially if
533 they are in non-standard paths.
534 * build system: Portability fixes: Automatically define "_REENTRANT"
535 if the libc expects it.
536 * collectd: Error and warning messages have been improved.
537 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
538 using them.
539 * apache plugin: Allocate new memory when reading a webpage instead of
540 using a buffer of static size.
541 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
542 the program.
543 * hddtemp plugin: Error and warning messages have been improved.
544 * sensors plugin: Fix sensor collection for some chip types.
546 2008-03-29, Version 4.3.2
547 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
548 `Persist' threshold options.
549 * collectd: Fix handling of missing values in the global value cache.
550 * collectd: Improved error messages when parsing the configuration.
551 * sensors plugin: Fix temperature collection with libsensors4.
552 * unixsock plugin: Fix mixed input and output operation on streams.
553 * wireless plugin: Fix reading noise value.
555 2008-03-05, Version 4.3.1
556 * exec plugin: Set supplementary group IDs.
557 * network plugin:
558 + Use `memcpy' when constructing/parsing a package to avoid
559 alignment problems on weird architectures, such as Sparc.
560 + Translate doubles to/from the x86 byte representation to ensure
561 cross-platform compatibility.
562 * ping plugin: Correct the handling of the `TTL' setting.
563 * swap plugin: Reapply a patch for Solaris.
564 * tcpconns plugin: Portability improvements.
566 2008-02-18, Version 4.3.0
567 * collectd: Notifications have been added to the daemon. Notifications
568 are status messages that may be associated with a data instance.
569 * collectd: Threshold checking has been added to the daemon. This
570 means that you can configure threshold values for each data
571 instance. If this threshold is exceeded a notification will be
572 created.
573 * collectd: The new `FQDNLookup' option tells the daemon to use the
574 full qualified domain name as the hostname, not just the host part
575 es returned by `gethostname(2)'.
576 * collectd: Support for more than one `TypesDB' file has been added.
577 This is useful when one such file is included in a package but one
578 wants to add custom type definitions.
579 * collectd: The `Include' config option has been expanded to handle
580 entire directories and shell wildcards.
581 * collectdmon: The new `collectdmon' binary detects when collectd
582 terminates and automatically restarts it again.
583 * csv plugin: The CSV plugin is now able to store counter values as a
584 rate, using the `StoreRates' configuration option.
585 * exec plugin: Handling of notifications has been added and the
586 ability to pass arguments to the executed programs has been added.
587 * hddtemp plugin: The new `TranslateDevicename' option lets you
588 disable the translation from device names to major-minor-numbers.
589 * logfile plugin: Handling of notifications has been added.
590 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
591 domain name lookups in this plugin.
592 * perl plugin: Many internal changes added support for handling multiple
593 threads making the plugin reasonably usable inside collectd. The API has
594 been extended to support notifications and export global variables to
595 Perl plugins; callbacks now have to be identified by name rather than a
596 pointer to a subroutine. The plugin is no longer experimental.
597 * uuid plugin: The new UUID plugin sets the hostname to an unique
598 identifier for this host. This is meant for setups where each client
599 may migrate to another physical host, possibly going through one or
600 more name changes in the process. Thanks to Richard Jones from
601 Red Hat's Emerging Technology group for this plugin.
602 * libvirt: The new libvirt plugin uses the `libvirt' library to query
603 CPU, disk and network statistics about guest systems on the same
604 physical server. Thanks to Richard Jones from Red Hat's Emerging
605 Technology group for this plugin.
607 2008-04-22, Version 4.2.7
608 * build system: Improved detection of several libraries, especially if
609 they are in non-standard paths.
610 * build system: Portability fixes: Automatically define "_REENTRANT"
611 if the libc expects it.
612 * collectd: Error and warning messages have been improved.
613 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
614 using them.
615 * apache plugin: Allocate new memory when reading a webpage instead of
616 using a buffer of static size.
617 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
618 the program.
619 * hddtemp plugin: Error and warning messages have been improved.
620 * sensors plugin: Fix sensor collection for some chip types.
622 2008-03-29, Version 4.2.6
623 * collectd: Improved error messages when parsing the configuration.
624 * sensors plugin: Fix temperature collection with libsensors4.
625 * unixsock plugin: Fix mixed input and output operation on streams.
626 * wireless plugin: Fix reading noise value.
628 2008-03-04, Version 4.2.5
629 * apache plugin: Improved initialization and error messages.
630 * exec plugin: Set supplementary group IDs.
631 * network plugin:
632 + Create separate threads for reading from the socket and parsing
633 and dispatching incoming packets. Versions prior to this may have
634 problems in high-load situations, where the socket receive buffers
635 overflows, resulting in gaps in the data.
636 + Use `memcpy' when constructing/parsing a package to avoid
637 alignment problems on weird architectures, such as Sparc.
638 + Translate doubles to/from the x86 byte representation to ensure
639 cross-platform compatibility.
640 * ping plugin: Correct the handling of the `TTL' setting.
641 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
642 * swap plugin: Reapply a patch for Solaris.
643 * tcpconns plugin: Portability improvements.
645 2008-01-21, Version 4.2.4
646 * unixsock plugin: A bug in the unixsock plugin caused it not to set
647 the permission on the socket as documented in the manpage. Thanks to
648 Evgeny Chukreev for fixing this issue.
649 * collectd: The documentation has been improved.
651 2007-12-28, Version 4.2.3
652 * sensors plugin: Updated the plugin to build and work with version 3
653 of the libsensors library.
655 2007-12-15, Version 4.2.2
656 * nginx plugin: Incorrect comparison of strings lead to a segfault
657 when using the plugin. Thanks to Saulius Grigaliunas for fixing
658 this.
659 * logfile plugin: The config option `Timestamp' was handled
660 incorrectly and basically always active. Thanks to Luke Heberling
661 for fixing this.
663 2007-11-08, Version 4.2.1
664 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
665 enabled on the host.
666 * snmp plugin: Fix a memory leak.
668 2007-10-27, Version 4.2.0
669 * collectd: The new config option `Include' lets you include other
670 configfiles and thus split up your config into smaller parts. This
671 may be especially interesting for the snmp plugin to keep the data
672 definitions separate from the host definitions.
673 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
674 (number of connections, octets and packets for each service and
675 destination). Thanks to Sebastian Harl for this plugin.
676 * memcached plugin: The new `memcached' plugin connects to a memcached
677 daemon process and collects statistics of this distributed caching
678 system. Thanks to Antony Dovgal for contributing this plugin.
679 * nginx plugin: The new `nginx' plugin reads the status page of an
680 nginx daemon and saves the handled connections and requests.
681 * perl plugin: Many changes, including the added `EnableDebugger'
682 config option which lets you debug your Perl plugins more easily.
683 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
684 be more thread-safe otherwise by locking calls to the library.
685 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
686 correct the values returned by SNMP-agents. If a <data> block is
687 defined as `table' the instance is now optional. The sequence number
688 is used as the type-instance in this case. The new `InstancePrefix'
689 option allows to add arbitrary prefixes to the type-instance.
690 * tcpconns plugin: The new `tcpconns' plugin collects the number of
691 certain TCP connections and what state they're in. This can be used
692 to see how many connections your FTP server has to handle or how
693 many outgoing connections your mailserver has open.
695 2008-01-11, Version 4.1.6
696 * unixsock plugin: A bug in the unixsock plugin caused it not to set
697 the permission on the socket as documented in the manpage. Thanks to
698 Evgeny Chukreev for fixing this issue.
699 * collectd: The documentation has been improved.
701 2007-12-27, Version 4.1.5
702 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
703 memory situations.
704 * sensors plugin: Updated the plugin to build and work with version 3
705 of the libsensors library.
707 2007-11-08, Version 4.1.4
708 * Build system: Improve detection of the rrd library, especially if
709 it's in a non-standard location.
710 * Build system: A bug when parsing the argument for
711 `--with-libnetsnmp' has been fixed.
712 * collectd: Implement `strerror_r' if the libc doesn't provide it.
713 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
714 a deadlock or delay when shutting down the daemon.
715 * snmp plugin: Fix a memory leak.
717 2007-10-24, Version 4.1.3
718 * collectd: A build issue under Solaris has been resolved by renaming
719 data types.
720 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
721 be more thread-safe otherwise by locking calls to the library.
723 2007-09-28, Version 4.1.2
724 * apcups plugin: Fix reporting of the `load percent' data.
725 * wireless plugin: Correct the handling of cards returning signal and
726 noise quality as percentage.
727 * perl plugin: Fix a possible buffer overflow in get_module_name().
728 * build system: Further improve the detection of libraries.
729 * netlink plugin: Build issues under some older versions of the Linux
730 includes (i. e. Debian Sarge) have been fixed.
731 * snmp plugin: Fix a potential segfault when a host times out. Add
732 support for the `timeticks' type.
734 2007-09-12, Version 4.1.1
735 * Build system: The detection of `libnetlink' has been improved.
736 * collectd: The documentation has been fixed in numerous places.
737 * exec plugin: Setting the group under which to run a program has been
738 fixed.
739 * collectd: The `sstrerror' function was improved to work correctly
740 with the broken GNU version of `strerror_r'.
741 * collectd: Write an error message to STDERR when loading of a plugin
742 fails.
743 * apcups plugin: Fix the `types' used to submit the values: They still
744 has an `apcups_' prefix which doesn't work anymore.
745 * rrdtool plugin: Create new RRD-files with the `begin' time set to
746 whatever the client thinks is `now'..
748 2007-09-01, Version 4.1.0
749 * Build system: The build system has been changed to automatically
750 disable all plugins, which are missing dependencies. The dependency
751 checking has been removed from the plugins themselves to remove
752 redundancy.
753 * Flexible interval: The interval of collected data is now sent along
754 with the data itself over the network, so that the interval-settings
755 of server and clients no longer needs to match.
756 * netlink plugin: The new `netlink' plugin connects to the Linux
757 kernel using a netlink socket and uses it to query information about
758 interfaces, qdiscs and classes.
759 * rrdtool plugin: The cache is now dumped to disk in an extra thread
760 to not block data collection.
761 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
762 network devices, such as switches, routers, thermometers, rack
763 monitoring servers, etc. The collectd-snmp(5) manpage documents this
764 plugin.
765 * unixsock plugin: Added the `LISTVAL' command.
766 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
767 of music played with xmms.
769 2007-09-28, Version 4.0.9
770 * apcups plugin: Fix reporting of the `load percent' data.
771 * wireless plugin: Correct the handling of cards returning signal and
772 noise quality as percentage.
773 * perl plugin: Fix a possible buffer overflow in get_module_name().
775 2007-09-12, Version 4.0.8
776 * collectd: The `sstrerror' function was improved to work correctly
777 with the broken GNU version of `strerror_r'.
778 * collectd: Write an error message to STDERR when loading of a plugin
779 fails.
780 * apcups plugin: Fix the `types' used to submit the values: They still
781 has an `apcups_' prefix which doesn't work anymore.
782 * rrdtool plugin: Create new RRD-files with the `begin' time set to
783 whatever the client thinks is `now'..
785 2007-08-26, Version 4.0.7
786 * documentation: Some typos have been fixed and some information has
787 been improved.
788 * build system: Many fixes for detecting libraries in unusual places,
789 such as on RedHat systems. The affected libraries are `libcurl',
790 `libmysql', and `libupsclient'.
791 * network plugin: Allow the `Port' option to be specified as a number
792 (i. e. without quotes).
793 * nut plugin: A fix allows linking the nut plugin against
794 libupsclient, version >= 2.2.0.
795 * processes plugin: Fix a potential segmentation fault.
797 2007-07-30, Version 4.0.6
798 * sensors plugin: Fix the ignorelist functionality: Only the `type
799 instance' was used to match against the list, but the documentation
800 told otherwise. This release fixes the code, so it complies with the
801 documentation.
802 * syslog plugin: Call `openlog' right when the plugin is loaded, so
803 configuration messages will end up in the logging facility.
804 * conrtib/fedora: The contributed specfile for Fedora has been
805 updated.
807 2007-07-05, Version 4.0.5
808 * Portability: More fixes for OpenBSD have been included.
810 2007-06-24, Version 4.0.4
811 * cpu plugin: Fixed the Solaris code.
812 * dns plugin: Fixed a build issue for OpenBSD.
813 * interface plugin: Fixed the Solaris code.
814 * load plugin: Fixed the alternative `/proc' Linux code.
815 * memory plugin: Fixed the Solaris code.
816 * oconfig: Don't require `-lfl' anymore.
818 2007-06-19, Version 4.0.3
819 * cpu plugin: Fix the Darwin / Mac OS X code.
820 * ping plugin: Use the return value of `getpid', not its address.
821 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
822 initialized correctly.
823 * configure: Added `--with-nan-emulation' to aid cross compilation.
825 2007-06-12, Version 4.0.2
826 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
827 they're given in numerically form.
829 2007-06-07, Version 4.0.1
830 * iptables plugin: A bug in the configuration routine has been fixed.
831 Setting a comment in the configfile will no longer cause a
832 segmentation fault.
834 2007-06-03, Version 4.0.0
835 * collectd: The plugin-infrastructure has been changed to allow for
836 more types of plugins, namely `write' and `log' plugins.
837 * collectd: The read-function has been changed to read many plugins in
838 parallel, using threads. Thus, plugins generally need to use
839 thread-safe functions from now on.
840 * collectd: The '-t' command line options allows to perform syntax tests
841 of the configuration file and exit immediately.
842 * csv plugin: The new `csv' plugin handles output to `comma separated
843 values'-files.
844 * rrdtool plugin: The new `rrdtool' plugin handles output to
845 RRD-files. Data can be cached to combine multiple updates into one
846 write to increase IO-performance.
847 * network plugin: The new `network' plugin handles IO via the network.
848 It implements a different, much more extensible protocol which can
849 combine many values in one packet, decreasing the number of UDP-
850 packets being sent. It can read from and send to the network and
851 with the appropriate configuration even forward packets to other
852 networks.
853 * unixsock plugin: The new `unixsock' plugin provides an interface to
854 communicate with the daemon while it is running. Right now the
855 commands `GETVAL' and `PUTVAL' are implemented, but more are to
856 come.
857 * perl plugin: The new `perl' plugin allows you to write extensions
858 for collectd in the scripting-language Perl.
859 * logfile plugin: The new `logfile' plugin writes logmessages to files
860 or STDOUT or STDERR.
861 * syslog plugin: The new `syslog' plugin sends logmessages to the
862 system's syslog daemon.
863 * entropy plugin: The new `entropy' plugin collects the amount of
864 entropy currently being available to the system.
865 * exec plugin: The new `exec' plugin forks child processes and reads
866 back values provided by the forked processes.
867 * iptables plugin: The new `iptables' plugin reads counters from
868 iptables rules. Thanks to Sjoerd van der Berg for contributing this
869 plugin.
870 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
871 to Peter Holik for contributing this plugin.
872 * nut plugin: The new `nut' plugin connects the upsd of the `network
873 ups tools' and reads information about the connected UPS.
874 * apache plugin: Support for lighttpd's `BusyServers' (aka.
875 connections) field was added by Florent Monbillard.
876 * collectd-nagios: The new `collectd-nagios' binary queries values
877 from collectd, parses them and exits according to Nagios-standards.
878 * manpages: The manpages have been improved a lot.
880 2007-09-28, Version 3.11.7
881 * wireless plugin: Correct the handling of cards returning signal and
882 noise quality as percentage.
884 2007-08-31, Version 3.11.6
885 * processes plugin: Fix a potential segmentation fault.
887 2007-05-29, Version 3.11.5
888 * configure: Added `AC_SYS_LARGEFILE' for LFS.
889 * ntpd plugin: Fix a potential buffer overflow.
890 * processes plugin: Fix a bug when run under Linux 2.4. All processes
891 were accounted as `zombies'.
893 2007-04-10, Version 3.11.4
894 * dns plugin: Change the order of includes to make the plugin compile
895 under FreeBSD.
897 2007-03-30, Version 3.11.3
898 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
899 of the unused `COLLECT_KSTAT'.
901 2007-02-11, Version 3.11.2
902 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
903 NULL-pointer may have been passed to `printf' which causes a
904 segfault with some libcs.
906 2007-02-10, Version 3.11.1
907 * df plugin: Some wrong defines have been fixed so the plugin works
908 under Solaris again.
909 * dns plugin: The usage of a struct has been fixed to work with
910 non-GNU libcs.
911 * processes plugin: Some missing defines have been added so the plugin
912 compiles cleanly under FreeBSD and presumably other UNIXes.
914 2006-12-22, Version 3.11.0
915 * collectd: The new command line option `-P' makes it easier for
916 distributors to change the location of PID-files.
917 * collectd: The daemon shuts down faster now which makes it easier to
918 write init.d-scripts for it.
919 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
920 caused problems every now and then.
921 * df plugin: New config options allow to ignore certain mountpoints,
922 filesystem types or devices.
923 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
924 and interprets it. It collects traffic as well as qtype, opcode and
925 rcode counts.
926 * email plugin: Sebastian Harl has contributed this plugin which
927 counts received mails in categories (e. g. ham, spam, virus), spam
928 score (as given by SpamAssassin) and check types.
929 * mbmon plugin: Flavio Stanchina has contributed this plugin which
930 uses `mbmon' to gather information from sensors on the motherboard.
931 * processes plugin: Collect detailed statistics for configured
932 processes, that's process and thread count, CPU usage, resident
933 segment size and pagefaults.
934 * multimeter plugin: Peter Holik contributed a new plugin which
935 queries multimeters.
936 * sensors plugin: Lubos Stanek has put much effort into improving this
937 plugin, including `extended naming', collection of voltage values
938 and the possibility to ignore certain values.
940 2006-12-21, Version 3.10.4
941 * Max Kellermann has identified a bug in the server routine: When
942 opening a socket fails the daemon will (re)try opening the socket in
943 an endless loop, ultimately leading to a `EMFILE' error.
945 2006-11-04, Version 3.10.3
946 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
947 ntpd's reply was sent in more than one packet, the buffer size was
948 calculated incorrectly, resulting in the reading of uninitialized or
949 freed memory.
951 2006-11-01, Version 3.10.2
952 * The sample config file has been improved.
953 * Errors in the manpages have been corrected.
954 * The ping-plugin now adds hosts during initialization, not during
955 startup. This speeds up startup when no network connectivity is
956 available. Also, the hosts are being added later when the network is
957 available.
958 * Improved BSD-support for the df-plugin.
959 * Fixed syntax errors in the swap-plugin for Mac OS X.
960 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
961 plugin.
962 * Don't disable the mysql-plugin if connecting to the database fails
963 during initialization. Instead, try again in increasing intervals.
965 2006-07-19, Version 3.10.1
966 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
967 the apcups cannot be reached, unconnected sockets will pile up and
968 eventually lead to `Too many open files' errors.
970 2006-07-09, Version 3.10.0
971 * The `disk' plugin has been ported to Darwin.
972 * The `battery' plugin should work on many Apple computers now.
973 * The `traffic' plugin can now ignore certain interfaces. Also,
974 statistics for sent/received packets and errors have been added.
975 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
976 to Anthony Gialluca for contributing this plugin and providing me
977 with a test environment :)
978 * A plugin for monitoring an NTP instance and the local clock drift
979 has been added.
981 2006-06-25, Version 3.9.4
982 * The Solaris code in the `swap' plugin has been changed to reflect
983 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
984 working this out.
985 * The debugging system has been fixed to work with the Sun libc.
986 * When built without librrd the variable `operating_mode' could be
987 uninitialized. Thanks to David Elliot for reporting the bug.
989 2006-06-01, Version 3.9.3
990 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
991 operating systems also profit from the changes, but I wasn't able to
992 check that.
993 * Changed the build system to find the netinet-includes under FreeBSD
994 and therefore successfully build the `liboping' library there.
996 2006-05-09, Version 3.9.2
997 * Applied a patch to the `liboping' library. Due to a bug in the
998 sequence checking the `ping' plugin stopped working after
999 approximately 7.6 days.
1001 2006-05-09, Version 3.8.5
1002 * Applied a patch to the `liboping' library. Due to a bug in the
1003 sequence checking the `ping' plugin stopped working after
1004 approximately 7.6 days.
1006 2006-04-21, Version 3.9.1
1007 * Build issues with Solaris and possible other architectures have been
1008 resolved.
1009 * Problems when building the `apache'-plugin without `libcurl' have
1010 been resolved.
1011 * A bug in the `ping' plugin has been fixed. Sorry folks.
1013 2006-04-02, Version 3.9.0
1014 * A plugin to monitor the Apache webserver has been added.
1015 <http://httpd.apache.org/>
1016 * A plugin to collect statistics about virtual servers using VServer.
1017 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
1018 this plugin :)
1019 * A plugin for wireless LAN cards has been added. It monitors signal
1020 strength, link quality and noise ratio..
1021 * A plugin for Apple hardware sensors has been added.
1022 * An option to compile collectd with different `step' and `heartbeat'
1023 settings has been added. The size of RRAs is no longer static but
1024 calculated based on the settings for `step' and `width'.
1025 * The `ping' plugin can now be configured to use a certain TTL.
1026 * A plugin to monitor the hardware sensors of Apple computers has been
1027 added.
1028 * The plugins `cpu', `memory', `processes' and `traffic' have been
1029 ported to Mach/Darwin (Mac OS X).
1030 * The `log mode' has been contributed by Christophe Kalt. It writes
1031 the data into text files rather than RRD files.
1033 2006-04-09, Version 3.8.4
1034 * Applied patch by Vincent Stehlé which improves the disk-name
1035 resolution in the `hddtemp' plugin for Linux systems.
1037 2006-04-02, Version 3.8.3
1038 * Applied a patch by James Byers: The MySQL plugin was not working
1039 with MySQL 5.0.2 or later.
1041 2006-03-14, Version 3.8.2
1042 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
1043 the GNU libc, because it points to `/etc/fstab' rather than
1044 `/etc/mtab'.
1046 2006-03-13, Version 3.8.1
1047 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
1048 * Fixes in the debian `postinst' and `init.d' scripts.
1050 2006-03-09, Version 3.8.0
1051 * The `ping' plugin no longer uses `libping' but a self written
1052 library named `liboping'. With this library it's possible to ping
1053 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
1055 2006-02-18, Version 3.7.2
1056 * A simple bug in the `battery' plugin has been fixed. It should now
1057 work with ACPI based batteries as well. Thanks to Sebastian for
1058 fixing this.
1059 * Fixing a bug that prevented collectd to be built without librrd.
1060 Thanks to Werner Heuser for reporting it.
1062 2006-02-04, Version 3.7.1
1063 * The new network code has been improved to build with older versions
1064 of glibc.
1065 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
1066 to Tommie Gannert for this patch.
1068 2006-01-30, Version 3.7.0
1069 * The `battery' plugin has been added. It collects information about
1070 laptop batteries..
1071 * The MySQL plugin has been improved: It now writes two more RRD
1072 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
1073 * The `cpufreq' plugin now reads another file since the file it did
1074 read so far causes much overhead in the kernel. Also, you need root
1075 to read the old file, but not to read the new one.
1076 * The `hddtemp' plugin can now be configured to connect to another
1077 address and/or port than localhost.
1078 * The `df' plugin now prefers `statvfs' over `statfs'.
1079 * The network code has been rewritten. collectd now supports unicast
1080 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
1081 be set in the configfile.
1083 2006-01-24, Version 3.6.2
1084 * Due to a bug in the configfile handling collectd wouldn't start in
1085 client mode. This released fixes this.
1087 2006-01-20, Version 3.6.1
1088 * Due to a bug in `configure.in' all modules and the binary were
1089 linked against `libmysqlclient'. This issue is solved by this
1090 release.
1092 2006-01-17, Version 3.6.0
1093 * A config file has been added. This allows for loading only specific
1094 plugins.
1095 * A `df' plugin has been added.
1096 * A `mysql' plugin has been added.
1097 * The `ping' plugin doesn't entirely give up hope when a socket error
1098 occurred, but will back of and increase the intervals between tries.
1100 2006-01-21, Version 3.5.2
1101 * Fixed yet another bug in the signal handling.. Stupid typo..
1102 * Improved the ping plugin to not give up on socket errors (backport
1103 from 3.6.0).
1105 2005-12-18, Version 3.5.1
1106 * The PID-file is now deleted correctly when shutting down the daemon.
1107 * SIGINT and SIGTERM are now handled correctly.
1109 2005-12-16, Version 3.5.0 (Revision 326)
1110 * A bug in the `load' module under Solaris has been fixed.
1111 * The `users' module has been contributed by Sebastian Harl. It counts
1112 currently logged in users.
1113 * The CPU module now works under FreeBSD without the use of
1114 `libstatgrab', however SMP support is missing.
1115 * The default directories for the RRD files and the PID file now
1116 depend on the compile time setting of `localstatedir'.
1118 2005-11-15, Version 3.4.0 (Revision 236)
1119 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1120 from gentoo's bugzilla for writing the patch.
1121 * The build dependency for librrd has been removed. Binaries built
1122 without librrd are client-only and will multicast their value as
1123 with the `-c' argument.
1124 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1125 * The newly introduced `-f' switch prevents daemon initialization
1126 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1127 Barcellos for this patch.
1129 2005-11-04, Version 3.3.0 (Revision 216)
1130 * New modules have been added:
1131 - `serial', for monitoring traffic on the serial interfaces
1132 - `nfs', for graphing NFS procedure calls
1133 - `tape', traffic from/to tape devices
1134 * The memory.rrd now accepts more than 4Gig of memory.
1136 2005-10-26, Version 3.2.0 (Revision 200)
1137 * Support for graphing the processes has been added (thanks to Lyonel
1138 Vincent)
1139 * If reading from hddtemp fails collectd will increase the time
1140 between polls up to one day.
1141 * The init.d files have been improved.
1142 * Problems with the spec file have been fixed.
1144 2005-10-16, Version 3.1.0 (Revision 194)
1145 * Added the `setsid' syscall to the startup code.
1146 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1148 2005-09-30, Version 3.0.0 (Revision 184)
1149 * The ability to send/receive data to/from the network (think
1150 multicast) has been added.
1151 * Modules have been split up into shared libraries can be loaded at
1152 runtime. The biggest advantage is that the core program doesn't need
1153 to be linked against an external library.
1154 * A patch by George Kargiotakis has been applied: It fixes the sensors
1155 behaviour then more than one sensor is being queried.
1157 2005-09-16, Version 2.1.0 (Revision 172)
1158 * A module for swap statistics has been added.
1160 2005-09-09, Version 2.0.0 (Revision 135)
1161 * Filenames can no longer be configured at program startup. The only
1162 options as of this version are the directory and ping hosts.
1163 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1164 Soft-IRQ statistics are added to `System'.
1165 * Diskstats now collect read and write bytes, not sectors.
1166 * Ping statistics can now be collected for more than one host. There
1167 is no default any more: If no host is given no host will be pinged.
1168 * A self-written patch for libping has been applied so it builds
1169 cleanly.
1171 2005-09-01, Version 1.8.1 (Revision 123)
1172 * Much improved configure-script: libraries and features may now be
1173 disabled.
1174 * More detailed warnings/error messages when RRD update fails.
1176 2005-08-29, Version 1.8.0:
1177 * Support for collecting disk statistics under Solaris.
1179 2005-08-25, Version 1.7.0:
1180 * Support for libstatgrab[1] for load, memory usage and network
1181 traffic. CPU- and disk-usage are not (yet) supported, since
1182 libstatgrab returns insufficient information. I will contact the
1183 authors.
1184 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1185 aren't necessarily counted linear which is now handled correctly.
1186 [1]: http://www.i-scream.org/libstatgrab/
1188 2005-08-21, Version 1.6.0:
1189 * Basic support for Solaris: System load and cpu-usage can be
1190 collected under Solaris, too. Other stats will follow later.
1191 * Many fixes in the autoconf-script
1192 * Collection/Museum scripts have been added under contrib/museum
1193 * collectd may now be started in unprivileged mode, though ping
1194 statistics will not work.
1196 2005-07-17, Version 1.5.1:
1197 * Diskstats-RRDs now use major/minor for naming. Some systems have
1198 weird strings as disk-names..
1200 2005-07-17, Version 1.5:
1201 * A new module, diskstats, has been added. It collects information
1202 about the disks and partitions.
1204 2005-07-11, Version 1.4.2:
1205 * The meminfo module has been changed to work with more platforms
1206 and/or kernel versions.
1208 2005-07-10, Version 1.4.1: Correct traffic stats
1209 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1210 forgot to correct when I changed that module.
1212 2005-07-09, Version 1.4: More traffic stats
1213 * Traffic is now collected for all interfaces that can be found
1214 * Temperature-statistics are read from lm-sensors if available
1216 2005-07-08, Version 1.3: CPU stats
1217 * Collecting CPU statistics now
1219 2005-07-12, Version 1.2: Using syslog
1220 * collectd is now using the syslog facility to report errors, warnings
1221 and the like..
1222 * The default directory is now /var/db/collectd
1224 2005-07-10, Version 1.1: Minor changes
1225 * Nothing really useful to say ;)
1227 2005-07-09, Version 1.0: Initial Version
1228 * The following modules are provided:
1229 * Load average
1230 * Ping time
1231 * Traffic
1232 * Memory info
