1 2009-09-10, Version 4.6.5
2 * collectd: Remove old values when a cache entry is marked as missing.
3 This way the “GETVAL” command of the UnixSock plugin doesn't return
4 old, no longer valid values when this happens. Thanks to Andrés J.
5 Díaz for the patch.
6 * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
7 to follow redirects. Thanks to Joey Hess for reporting this bug.
8 * df plugin: Check the ignorelist before stating the file system,
9 possibly reducing the number of stats considerably. Thanks to Joey
10 Hess for reporting this bug.
11 * iptables plugin: Support for the new libiptc API has been added.
12 Thanks to Sebastian Harl for the patch. The build system has been
13 updated to the plugin only includes the shipped header files when it
14 is linked with the shipped library, too.
15 * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
16 to Alan Pevec for the patch.
17 * powerdns plugin: Set a timeout when reading data from the datagram
18 socket. Handling of the “LocalSocket” option has been fixed. An
19 incorrectly used “type” has been corrected. Thanks to Luke Heberling
20 for his patches.
22 2009-07-18, Version 4.6.4
23 * collectd: Okay-notifications have been fixed. Thanks to Andrés J.
24 Díaz for fixing this bug.
25 * collectd: A programming error has been fixed in the notification
26 code. The bug may result in an assertion failure.
27 * memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
28 for reporting the bug.
30 2009-06-02, Version 4.6.3
31 * Build system, various plugins: Many build fixes for FreeBSD,
32 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
33 for many fixes and providing a build system for many platforms,
34 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
35 providing an OpenBSD system.
36 * collectd: Two bugs with the threshold checking have been fixed. The
37 first one prevented thresholds to be checked at all, the second one
38 caused wrong behavior with the persistency option. Thanks to Andrés
39 J. Díaz for fixing these problems.
40 * collectd: Handling of the `Include' configuration option has been
41 fixed.
42 * battery plugin: Don't complain about a missing directory every
43 interval.
44 * exec plugin: Allow executed programs to close STDERR. Thanks to
45 Thorsten von Eicken for reporting this problem.
46 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
47 Tomasz Pala for the patch.

55 * collectd: Some Solaris utility code has been improved.
56 * filter subsystem: Allow `Chains' without default targets.
57 * liboping: A patch to comply with strict aliasing rules has been
58 added.
59 * timediff match: Fix a typo: The match was registered with a wrong
60 name which prevented this match to be used as documented. Thanks to
61 Bruno Prémont for finding this problem.
62 * bind plugin: Fix collection of the cached RR sets. The number of RR
63 sets currently in the cache was collected as a counter value, which
64 is nonsense. Thanks to Bruno Prémont for implementing this.
65 * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
66 primarily BSDs, don't take it well and crash.
67 * oracle plugin: Portability to 64 bit systems has been improved.
68 * postgresql plugin: The default configuration has been improved.
69 * rrdtool plugin: Fix a possible race condition: If the network plugin
70 is brought and dispatches a value before the rrdtool plugin is
71 initialized, the daemon may crash.
73 2009-02-22, Version 4.6.1
74 * collectd: Many documentation fixes.
75 * Collectd::Unixsock: Error handling has been improved.
76 * regex match: Don't link with the PCRE library.
77 * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
78 for finding and fixing most of them.
79 * ipmi plugin: Fix an off-by-one error which could cause segmentation
80 faults. Thanks to Peter Holik for his patch.
82 2009-02-16, Version 4.6.0
83 * collectd: Added the `filter chain' infrastructure, which allows the
84 user to use `matches' and `targets' to control value processing.
85 * collectd: The new `-T' command line argument allows more in-depth
86 testing of a configuration. Thanks to Doug MacEachern for the patch.
87 * collectd-nagios: The Nagios integration command has been updated to
88 use libcollectdclient. The `percentage' aggregation function has
89 been added. Thanks to Fabian Linzberger for the patch.
90 * libcollectdclient: A library which abstracts communication with the
91 unixsock plugin for clients has been added.
92 * regex match: Match values by their identifies using regular
93 expressions.
94 * timediff match: Match for values with an invalid timestamp.
95 * value match: Select values by their data sources' values.
96 * notification target: Create and dispatch a notification.
97 * replace target: Replace parts of an identifier using regular
98 expressions.
99 * set target: Set (overwrite) entire parts of an identifier.
100 * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
101 statistics, allowing very detailed name server statistics. Thanks to
102 Bruno Prémont for this plugin.
103 * cpu plugin: Report `interrupt' separately when using
104 sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
105 example for native OpenBSD support, has been added. Thanks to Simon
106 Kuhnle for the patch.
107 * csv plugin: Make it possible to write values to STDOUT instead of
108 files. This is meant for testing purposes mostly. The output written
109 to STDOUT is compatible with the exec plugin. Thanks to Doug
110 MacEachern for the patch.
111 * curl plugin: This new plugin can be used to read web pages and parse
112 them using the same mechanism that's used in the tail plugin.
113 * dbi plugin: This new plugin allows you to connect to a variety of
114 relational databases and use SQL to gather custom statistics from
115 it. It is similar to the already existing PostgreSQL plugin but uses
116 libdbi to communicate with the database(s).
117 * interface plugin: Use the ignorelist framework when selecting /
118 ignoring interfaces. This allows one to use regular expressions to
119 select interfaces, too.
120 * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
121 Thanks to Bruno Prémont for this patch.
122 * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
123 for the patch.
124 * mysql plugin: Allow connecting to a database via the UNIX domain
125 socket, too. Thanks to Mirko Buffoni for the patch.
126 * network plugin: Further performance improvements for the receive
127 code. This hopefully will help very large setups.
128 * openvpn plugin: This new plugin collects statistics provided by the
129 OpenVPN daemon. Thanks to Doug MacEachern for the patch.
130 * oracle plugin: This new plugin allows you to connect to an Oracle
131 database and use SQL to gather custom statistics from it. It is
132 similar to the already existing PostgreSQL plugin.
133 * perl plugin: Compatibility fixes for broken versions of Perl 5.10
134 have been added.
135 * perl plugin: Export the newly added plugin_write() to Perl plugins.
136 * perl plugin: Added support for `notification meta data'.
137 * perl plugin: Added support for the `filter chain' infrastructure by
138 allowing plugins to register `matches' and `targets'.
139 * postgresql plugin: The preferred configuration syntax has been
140 updated to be in line with the syntax used by the new dbi and oracle
141 plugins. The compatibility code for the old syntax is present.
142 Support for the new `Result' blocks and the interval parameter has
143 been added.
144 * processes plugin: Stacksize and virtual memory usage statistics have
145 been added. Portability fixes.
146 * rrdcached plugin: This new plugin uses the (still in development)
147 RRD accelerator daemon, rrdcached. This daemon works very similar to
148 the original rrdtool plugin of collectd, but adds some more nice
149 features.
150 * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
151 added.
153 2009-05-09, Version 4.5.4
154 * Build system, various plugins: Many build fixes for FreeBSD,
155 OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
156 for many fixes and providing a build system for many platforms,
157 Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
158 providing an OpenBSD system.
159 * collectd: Fix a potential race condition when creating directories.
160 * battery plugin: Don't complain about a missing directory every
161 interval.
162 * dns plugin: Slight portability fixes.
163 * exec plugin: Allow executed programs to close STDERR. Thanks to
164 Thorsten von Eicken for reporting this problem.
165 * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
166 Tomasz Pala for the patch.
167 * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
168 the patch.
169 * rrdtool plugin: Fix a possible race condition: If the network plugin
170 is initialized and dispatches a value before the rrdtool plugin is
171 initialized, the daemon may crash.
172 * memory plugin: Fix a potential problem under Solaris.
174 2009-02-22, Version 4.5.3
175 * build system: The check for libupsclient even when `pkg-config' is
176 not available.
177 * collectd: Fix error handling in the global cache.
178 * Collectd::Unixsock: Error handling has been improved.
179 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
180 patch.

182 faults. Thanks to Peter Holik for his patch.
183 * tcpconns plugin: An endianness problem has been fixed in the *BSD
184 code. Thanks to "thated" for reporting this.
186 2009-01-02, Version 4.5.2
187 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
188 file may be in both locations, especially when the database was
189 installed in a non-standard path. Thanks to Dusty Doris for
190 reporting this.
191 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
192 Solaris, in the configure script automatically.
193 * build system, tcpconns plugin: Check for `kvm_nlist' and
194 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
195 library with similar functions to the BSD variant, but doesn't
196 provide these necessary functions.
197 * collectd.conf(5): Various fixes and clarifications.
198 * collectd: Remove a GNUism (unnamed unions), thus improving
199 portability.
200 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
201 This solves portability problems, especially for Solaris.
202 * dns plugin: Fix a portability problem with NetBSD.
203 * filecount plugin: Fix an off-by-one error. This error may cause a
204 segmentation fault.
205 * network plugin: Fix the handling of `type' in the network protocol.
206 Due to a programming mistake, only 4 or 8 bytes would be copied to a
207 much larger buffer. This caused the `type' to be transferred much
208 more often than necessary. In some cases, e. g. the `cpu' and
209 `cpufreq' plugins being used at the same time, data may be corrupted
210 in those files. Thanks to Bruno Prémont for debugging and reporting
211 this issue.
212 * processes plugin: Fix a possible segmentation fault when specifying
213 invalid configuration options.
214 * unixsock plugin: Make sure the initialization function is run only
215 once. This resolves a file descriptor leak under systems which run
216 the initialization more than once, such as Solaris.
218 2008-10-16, Version 4.5.1
219 * build system: Change `--enable-<plugin>' to abort with an error if
220 dependencies are not met. Thanks to Bruno Prémont for the patch.
221 Also, the poisoning of various string functions has been restricted
222 to debug builds.
223 * collectd: Fix a memory leak in the global value cache. With every
224 *missing* value a couple of bytes would be leaked. Another memory
225 leak in the configuration handling code has been fixed. Thanks to
226 Niraj Tolia for reporting these issues.
227 * collectd: Fix an off-by-one error in the ignorelist functionality.
228 When using regular expressions, the last character would be missing,
229 possibly matching differently from what one would expect.
230 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
231 problem.
232 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
233 Linzberger for reporting the bug.
234 * iptables plugin: Fix an off-by-one error. If a string was just one
235 character too long, it was truncated instead of reporting an error.
236 * network plugin: Fix a memory leak in the configuration handling
237 code. Thanks to Niraj Tolia for reporting this issue.
238 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
239 * postgresql plugin: Don't reopen connection during reinitialization.
240 This fixes a bug under Solaris and potentially other platforms.
241 Missing calls to `PQclear' have been added, too. This fixes memory
242 leaks. Thanks to ``Admin'' for reporting these bugs.
243 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
244 library.
245 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
246 problems with some `libc's. Thanks to Matthias Lay for reporting the
247 bug.
249 2008-09-04, Version 4.5.0
250 * collectd: Added the ability to flush certain identifiers.
251 * collectd: The concept of `notification meta data' has been
252 introduced.
253 * filecount plugin: The new filecount plugin counts the number of
254 files in a directory and its subdirectories.
255 * ipmi plugin: Sensor names have been changed to ensure unique names.
256 Notifications upon added and removed sensors can now be generated.
257 * notify_desktop plugin: This new plugin sends notifications to the
258 X desktop using the structure defined in the `Desktop Notification
259 Specification'.
260 * notify_email plugin: This new plugin sends out notifications via
261 email, using the `esmtp' library.
262 * onewire plugin: The new experimental(!) onewire plugin reads values,
263 such as temperatures, from sensors connected to the computer via the
264 onewire bus.
265 * perl plugin: Improved synchronized access to internal data structures
266 and fixed a possible dead-lock.
267 * perl plugin: Added the ability to flush certain identifiers and marked
268 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
269 plugin_flush().
270 * perl plugin: Added the ability to configure Perl plugins.
271 * postgresql plugin: The new postgresql plugin collects statistics
272 about or from a PostgreSQL database.
273 * processes plugin: The `ProcessMatch' option has been added.
274 * rrdtool plugin: Implement throttling of the `update queue' to lessen
275 IO load.
276 * tcpconns plugin: This plugin has been ported to OpenBSD.
277 * thermal plugin: The new thermal plugin collects system temperatures
278 using Linux ACPI thermal zone data.
280 2009-01-02, Version 4.4.5
281 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
282 file may be in both locations, especially when the database was
283 installed in a non-standard path. Thanks to Dusty Doris for
284 reporting this.
285 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
286 Solaris, in the configure script automatically.
287 * collectd.conf(5): Various fixes and clarifications.
288 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
289 portability problems, especially for Solaris.
290 * dns plugin: Fix a portability problem with NetBSD.
291 * network plugin: Fix the handling of `type' in the network protocol.
292 Due to a programming mistake, only 4 or 8 bytes would be copied to a
293 much larger buffer. This caused the `type' to be transferred much
294 more often than necessary. In some cases, e. g. the `cpu' and
295 `cpufreq' plugins being used at the same time, data may be corrupted
296 in those files. Thanks to Bruno Prémont for debugging and reporting
297 this issue.
298 * unixsock plugin: Make sure the initialization function is run only
299 once. This resolves a file descriptor leak under systems which run
300 the initialization more than once, such as Solaris.
302 2008-10-16, Version 4.4.4
303 * build system: Change `--enable-<plugin>' to abort with an error if
304 dependencies are not met. Thanks to Bruno Prémont for the patch.
305 Also, the poisoning of various string functions has been restricted
306 to debug builds.
307 * collectd: Fix a memory leak in the global value cache. With every
308 *missing* value a couple of bytes would be leaked. Another memory
309 leak in the configuration handling code has been fixed. Thanks to
310 Niraj Tolia for reporting these issues.
311 * collectd: Fix an off-by-one error in the ignorelist functionality.
312 When using regular expressions, the last character would be missing,
313 possibly matching differently from what one would expect.
314 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
315 problem.
316 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian

337 of disks.
338 * dns plugin: Fix compilation errors with BIND versions 19991001
339 through 19991005.
340 * network plugin: Bugfix in the init routine: The init function
341 cleared a buffer regardless of its contents. This could lead to lost
342 values under Solaris.
343 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
344 * vserver plugin: Remove usage of the thread-unsafe `readdir'
345 function.

357 initialization has errors. An issue with Perl 5.10 has been fixed.
358 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
359 René Rebe and Siegmund Gorr for reporting this.
361 2008-05-06, Version 4.4.0
362 * collectd: Internal code cleanups.
363 * collectd: Added support for a `Flush' command in the unixsock and
364 exec plugins. This command can be used to force a plugin (or all) to
365 flush its values to disk.
366 * collectd: Thresholds can now be configured to apply to one data
367 source only, making it possible to configure different thresholds
368 for each data source.
369 * apache, nginx plugins: Added the possibility to disable host and/or
370 peer verification.
371 * ascent plugin: The new ascent plugin reads and parses the statistics
372 page of an Ascent server.

378 sensor values via IPMI, the intelligent platform management
379 interface.
380 * iptables plugin: The iptc library that is used by the iptables
381 plugin has been added to the distribution, because it is not
382 provided by all distributions and removed from at least one.

384 authoritative or a recursing PowerDNS name server.
385 * rrdtool plugin: The size of the files generated with the default
386 configuration has been decreased.
387 * tail plugin: The new tail plugin can be used to gather statistics by
388 continuously reading from log files.
389 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
390 TeamSpeak2 server and collects statistics about the number of users
391 and number of channels.
392 * users plugin: Support for the statgrab library has been added.
393 * vmem plugin: The new vmem plugin collects very detailed statistics
394 about the virtual memory subsystem of Linux.

445 * ping plugin: Correct the handling of the `TTL' setting.
446 * swap plugin: Reapply a patch for Solaris.
447 * tcpconns plugin: Portability improvements.
449 2008-02-18, Version 4.3.0
450 * collectd: Notifications have been added to the daemon. Notifications
451 are status messages that may be associated with a data instance.
452 * collectd: Threshold checking has been added to the daemon. This
453 means that you can configure threshold values for each data
454 instance. If this threshold is exceeded a notification will be
455 created.
456 * collectd: The new `FQDNLookup' option tells the daemon to use the
457 full qualified domain name as the hostname, not just the host part
458 es returned by `gethostname(2)'.
459 * collectd: Support for more than one `TypesDB' file has been added.
460 This is useful when one such file is included in a package but one
461 wants to add custom type definitions.
462 * collectd: The `Include' config option has been expanded to handle
463 entire directories and shell wildcards.
464 * collectdmon: The new `collectdmon' binary detects when collectd
465 terminates and automatically restarts it again.
466 * csv plugin: The CSV plugin is now able to store counter values as a
467 rate, using the `StoreRates' configuration option.
468 * exec plugin: Handling of notifications has been added and the
469 ability to pass arguments to the executed programs has been added.
470 * hddtemp plugin: The new `TranslateDevicename' option lets you
471 disable the translation from device names to major-minor-numbers.
472 * logfile plugin: Handling of notifications has been added.
473 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
474 domain name lookups in this plugin.
475 * perl plugin: Many internal changes added support for handling multiple
476 threads making the plugin reasonably usable inside collectd. The API has
477 been extended to support notifications and export global variables to
478 Perl plugins; callbacks now have to be identified by name rather than a
479 pointer to a subroutine. The plugin is no longer experimental.
480 * uuid plugin: The new UUID plugin sets the hostname to an unique
481 identifier for this host. This is meant for setups where each client
482 may migrate to another physical host, possibly going through one or
483 more name changes in the process. Thanks to Richard Jones from
484 Red Hat's Emerging Technology group for this plugin.
485 * libvirt: The new libvirt plugin uses the `libvirt' library to query
486 CPU, disk and network statistics about guest systems on the same
487 physical server. Thanks to Richard Jones from Red Hat's Emerging
488 Technology group for this plugin.
490 2008-04-22, Version 4.2.7
491 * build system: Improved detection of several libraries, especially if
492 they are in non-standard paths.
493 * build system: Portability fixes: Automatically define "_REENTRANT"
494 if the libc expects it.
495 * collectd: Error and warning messages have been improved.
496 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
497 using them.
498 * apache plugin: Allocate new memory when reading a webpage instead of
499 using a buffer of static size.
500 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
501 the program.
502 * hddtemp plugin: Error and warning messages have been improved.
503 * sensors plugin: Fix sensor collection for some chip types.
505 2008-03-29, Version 4.2.6
506 * collectd: Improved error messages when parsing the configuration.
507 * sensors plugin: Fix temperature collection with libsensors4.
508 * unixsock plugin: Fix mixed input and output operation on streams.
509 * wireless plugin: Fix reading noise value.
511 2008-03-04, Version 4.2.5
512 * apache plugin: Improved initialization and error messages.
513 * exec plugin: Set supplementary group IDs.
514 * network plugin:
515 + Create separate threads for reading from the socket and parsing
516 and dispatching incoming packets. Versions prior to this may have
517 problems in high-load situations, where the socket receive buffers
518 overflows, resulting in gaps in the data.
519 + Use `memcpy' when constructing/parsing a package to avoid
520 alignment problems on weird architectures, such as Sparc.
521 + Translate doubles to/from the x86 byte representation to ensure
522 cross-platform compatibility.
523 * ping plugin: Correct the handling of the `TTL' setting.
524 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
525 * swap plugin: Reapply a patch for Solaris.
526 * tcpconns plugin: Portability improvements.
528 2008-01-21, Version 4.2.4
529 * unixsock plugin: A bug in the unixsock plugin caused it not to set
530 the permission on the socket as documented in the manpage. Thanks to
531 Evgeny Chukreev for fixing this issue.
532 * collectd: The documentation has been improved.
534 2007-12-28, Version 4.2.3
535 * sensors plugin: Updated the plugin to build and work with version 3
536 of the libsensors library.
538 2007-12-15, Version 4.2.2
539 * nginx plugin: Incorrect comparison of strings lead to a segfault
540 when using the plugin. Thanks to Saulius Grigaliunas for fixing
541 this.
542 * logfile plugin: The config option `Timestamp' was handled
543 incorrectly and basically always active. Thanks to Luke Heberling
544 for fixing this.
546 2007-11-08, Version 4.2.1
547 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
548 enabled on the host.
549 * snmp plugin: Fix a memory leak.
551 2007-10-27, Version 4.2.0
552 * collectd: The new config option `Include' lets you include other
553 configfiles and thus split up your config into smaller parts. This
554 may be especially interesting for the snmp plugin to keep the data
555 definitions separate from the host definitions.
556 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
557 (number of connections, octets and packets for each service and
558 destination). Thanks to Sebastian Harl for this plugin.
559 * memcached plugin: The new `memcached' plugin connects to a memcached
560 daemon process and collects statistics of this distributed caching
561 system. Thanks to Antony Dovgal for contributing this plugin.
562 * nginx plugin: The new `nginx' plugin reads the status page of an
563 nginx daemon and saves the handled connections and requests.
564 * perl plugin: Many changes, including the added `EnableDebugger'
565 config option which lets you debug your Perl plugins more easily.
566 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
567 be more thread-safe otherwise by locking calls to the library.
568 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
569 correct the values returned by SNMP-agents. If a <data> block is
570 defined as `table' the instance is now optional. The sequence number
571 is used as the type-instance in this case. The new `InstancePrefix'
572 option allows to add arbitrary prefixes to the type-instance.
573 * tcpconns plugin: The new `tcpconns' plugin collects the number of
574 certain TCP connections and what state they're in. This can be used
575 to see how many connections your FTP server has to handle or how
576 many outgoing connections your mailserver has open.
578 2008-01-11, Version 4.1.6
579 * unixsock plugin: A bug in the unixsock plugin caused it not to set
580 the permission on the socket as documented in the manpage. Thanks to
581 Evgeny Chukreev for fixing this issue.
582 * collectd: The documentation has been improved.
584 2007-12-27, Version 4.1.5
585 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
586 memory situations.
587 * sensors plugin: Updated the plugin to build and work with version 3
588 of the libsensors library.
590 2007-11-08, Version 4.1.4
591 * Build system: Improve detection of the rrd library, especially if
592 it's in a non-standard location.
593 * Build system: A bug when parsing the argument for
594 `--with-libnetsnmp' has been fixed.
595 * collectd: Implement `strerror_r' if the libc doesn't provide it.
596 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
597 a deadlock or delay when shutting down the daemon.
598 * snmp plugin: Fix a memory leak.
600 2007-10-24, Version 4.1.3
601 * collectd: A build issue under Solaris has been resolved by renaming
602 data types.
603 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
604 be more thread-safe otherwise by locking calls to the library.
606 2007-09-28, Version 4.1.2
607 * apcups plugin: Fix reporting of the `load percent' data.
608 * wireless plugin: Correct the handling of cards returning signal and
609 noise quality as percentage.
610 * perl plugin: Fix a possible buffer overflow in get_module_name().
611 * build system: Further improve the detection of libraries.
612 * netlink plugin: Build issues under some older versions of the Linux
613 includes (i. e. Debian Sarge) have been fixed.
614 * snmp plugin: Fix a potential segfault when a host times out. Add
615 support for the `timeticks' type.
617 2007-09-12, Version 4.1.1
618 * Build system: The detection of `libnetlink' has been improved.
619 * collectd: The documentation has been fixed in numerous places.
620 * exec plugin: Setting the group under which to run a program has been
621 fixed.
622 * collectd: The `sstrerror' function was improved to work correctly
623 with the broken GNU version of `strerror_r'.
624 * collectd: Write an error message to STDERR when loading of a plugin
625 fails.
626 * apcups plugin: Fix the `types' used to submit the values: They still
627 has an `apcups_' prefix which doesn't work anymore.
628 * rrdtool plugin: Create new RRD-files with the `begin' time set to
629 whatever the client thinks is `now'..
631 2007-09-01, Version 4.1.0
632 * Build system: The build system has been changed to automatically
633 disable all plugins, which are missing dependencies. The dependency
634 checking has been removed from the plugins themselves to remove
635 redundancy.
636 * Flexible interval: The interval of collected data is now sent along
637 with the data itself over the network, so that the interval-settings
638 of server and clients no longer needs to match.
639 * netlink plugin: The new `netlink' plugin connects to the Linux
640 kernel using a netlink socket and uses it to query information about
641 interfaces, qdiscs and classes.
642 * rrdtool plugin: The cache is now dumped to disk in an extra thread
643 to not block data collection.
644 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
645 network devices, such as switches, routers, thermometers, rack
646 monitoring servers, etc. The collectd-snmp(5) manpage documents this
647 plugin.
648 * unixsock plugin: Added the `LISTVAL' command.
649 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
650 of music played with xmms.
652 2007-09-28, Version 4.0.9
653 * apcups plugin: Fix reporting of the `load percent' data.
654 * wireless plugin: Correct the handling of cards returning signal and
655 noise quality as percentage.
656 * perl plugin: Fix a possible buffer overflow in get_module_name().
658 2007-09-12, Version 4.0.8
659 * collectd: The `sstrerror' function was improved to work correctly
660 with the broken GNU version of `strerror_r'.
661 * collectd: Write an error message to STDERR when loading of a plugin
662 fails.
663 * apcups plugin: Fix the `types' used to submit the values: They still
664 has an `apcups_' prefix which doesn't work anymore.
665 * rrdtool plugin: Create new RRD-files with the `begin' time set to
666 whatever the client thinks is `now'..
668 2007-08-26, Version 4.0.7
669 * documentation: Some typos have been fixed and some information has
670 been improved.
671 * build system: Many fixes for detecting libraries in unusual places,
672 such as on RedHat systems. The affected libraries are `libcurl',
673 `libmysql', and `libupsclient'.
674 * network plugin: Allow the `Port' option to be specified as a number
675 (i. e. without quotes).
676 * nut plugin: A fix allows linking the nut plugin against
677 libupsclient, version >= 2.2.0.
678 * processes plugin: Fix a potential segmentation fault.
680 2007-07-30, Version 4.0.6
681 * sensors plugin: Fix the ignorelist functionality: Only the `type
682 instance' was used to match against the list, but the documentation
683 told otherwise. This release fixes the code, so it complies with the
684 documentation.
685 * syslog plugin: Call `openlog' right when the plugin is loaded, so
686 configuration messages will end up in the logging facility.
687 * conrtib/fedora: The contributed specfile for Fedora has been
688 updated.
690 2007-07-05, Version 4.0.5
691 * Portability: More fixes for OpenBSD have been included.
693 2007-06-24, Version 4.0.4
694 * cpu plugin: Fixed the Solaris code.
695 * dns plugin: Fixed a build issue for OpenBSD.
696 * interface plugin: Fixed the Solaris code.
697 * load plugin: Fixed the alternative `/proc' Linux code.
698 * memory plugin: Fixed the Solaris code.
699 * oconfig: Don't require `-lfl' anymore.
701 2007-06-19, Version 4.0.3
702 * cpu plugin: Fix the Darwin / Mac OS X code.
703 * ping plugin: Use the return value of `getpid', not its address.
704 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
705 initialized correctly.
706 * configure: Added `--with-nan-emulation' to aid cross compilation.
708 2007-06-12, Version 4.0.2
709 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
710 they're given in numerically form.
712 2007-06-07, Version 4.0.1
713 * iptables plugin: A bug in the configuration routine has been fixed.
714 Setting a comment in the configfile will no longer cause a
715 segmentation fault.
717 2007-06-03, Version 4.0.0
718 * collectd: The plugin-infrastructure has been changed to allow for
719 more types of plugins, namely `write' and `log' plugins.
720 * collectd: The read-function has been changed to read many plugins in
721 parallel, using threads. Thus, plugins generally need to use
722 thread-safe functions from now on.
723 * collectd: The '-t' command line options allows to perform syntax tests
724 of the configuration file and exit immediately.
725 * csv plugin: The new `csv' plugin handles output to `comma separated
726 values'-files.
727 * rrdtool plugin: The new `rrdtool' plugin handles output to
728 RRD-files. Data can be cached to combine multiple updates into one
729 write to increase IO-performance.
730 * network plugin: The new `network' plugin handles IO via the network.
731 It implements a different, much more extensible protocol which can
732 combine many values in one packet, decreasing the number of UDP-
733 packets being sent. It can read from and send to the network and
734 with the appropriate configuration even forward packets to other
735 networks.
736 * unixsock plugin: The new `unixsock' plugin provides an interface to
737 communicate with the daemon while it is running. Right now the
738 commands `GETVAL' and `PUTVAL' are implemented, but more are to
739 come.
740 * perl plugin: The new `perl' plugin allows you to write extensions
741 for collectd in the scripting-language Perl.
742 * logfile plugin: The new `logfile' plugin writes logmessages to files
743 or STDOUT or STDERR.
744 * syslog plugin: The new `syslog' plugin sends logmessages to the
745 system's syslog daemon.
746 * entropy plugin: The new `entropy' plugin collects the amount of
747 entropy currently being available to the system.
748 * exec plugin: The new `exec' plugin forks child processes and reads
749 back values provided by the forked processes.
750 * iptables plugin: The new `iptables' plugin reads counters from
751 iptables rules. Thanks to Sjoerd van der Berg for contributing this
752 plugin.
753 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
754 to Peter Holik for contributing this plugin.
755 * nut plugin: The new `nut' plugin connects the upsd of the `network
756 ups tools' and reads information about the connected UPS.
757 * apache plugin: Support for lighttpd's `BusyServers' (aka.
758 connections) field was added by Florent Monbillard.
759 * collectd-nagios: The new `collectd-nagios' binary queries values
760 from collectd, parses them and exits according to Nagios-standards.
761 * manpages: The manpages have been improved a lot.
763 2007-09-28, Version 3.11.7
764 * wireless plugin: Correct the handling of cards returning signal and
765 noise quality as percentage.
767 2007-08-31, Version 3.11.6
768 * processes plugin: Fix a potential segmentation fault.
770 2007-05-29, Version 3.11.5
771 * configure: Added `AC_SYS_LARGEFILE' for LFS.
772 * ntpd plugin: Fix a potential buffer overflow.
773 * processes plugin: Fix a bug when run under Linux 2.4. All processes
774 were accounted as `zombies'.
776 2007-04-10, Version 3.11.4
777 * dns plugin: Change the order of includes to make the plugin compile
778 under FreeBSD.
780 2007-03-30, Version 3.11.3
781 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
782 of the unused `COLLECT_KSTAT'.
784 2007-02-11, Version 3.11.2
785 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
786 NULL-pointer may have been passed to `printf' which causes a
787 segfault with some libcs.
789 2007-02-10, Version 3.11.1
790 * df plugin: Some wrong defines have been fixed so the plugin works
791 under Solaris again.
792 * dns plugin: The usage of a struct has been fixed to work with
793 non-GNU libcs.
794 * processes plugin: Some missing defines have been added so the plugin
795 compiles cleanly under FreeBSD and presumably other UNIXes.
797 2006-12-22, Version 3.11.0
798 * collectd: The new command line option `-P' makes it easier for
799 distributors to change the location of PID-files.
800 * collectd: The daemon shuts down faster now which makes it easier to
801 write init.d-scripts for it.
802 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
803 caused problems every now and then.
804 * df plugin: New config options allow to ignore certain mountpoints,
805 filesystem types or devices.
806 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
807 and interprets it. It collects traffic as well as qtype, opcode and
808 rcode counts.
809 * email plugin: Sebastian Harl has contributed this plugin which
810 counts received mails in categories (e. g. ham, spam, virus), spam
811 score (as given by SpamAssassin) and check types.
812 * mbmon plugin: Flavio Stanchina has contributed this plugin which
813 uses `mbmon' to gather information from sensors on the motherboard.
814 * processes plugin: Collect detailed statistics for configured
815 processes, that's process and thread count, CPU usage, resident
816 segment size and pagefaults.
817 * multimeter plugin: Peter Holik contributed a new plugin which
818 queries multimeters.
819 * sensors plugin: Lubos Stanek has put much effort into improving this
820 plugin, including `extended naming', collection of voltage values
821 and the possibility to ignore certain values.
823 2006-12-21, Version 3.10.4
824 * Max Kellermann has identified a bug in the server routine: When
825 opening a socket fails the daemon will (re)try opening the socket in
826 an endless loop, ultimately leading to a `EMFILE' error.
828 2006-11-04, Version 3.10.3
829 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
830 ntpd's reply was sent in more than one packet, the buffer size was
831 calculated incorrectly, resulting in the reading of uninitialized or
832 freed memory.
834 2006-11-01, Version 3.10.2
835 * The sample config file has been improved.
836 * Errors in the manpages have been corrected.
837 * The ping-plugin now adds hosts during initialization, not during
838 startup. This speeds up startup when no network connectivity is
839 available. Also, the hosts are being added later when the network is
840 available.
841 * Improved BSD-support for the df-plugin.
842 * Fixed syntax errors in the swap-plugin for Mac OS X.
843 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
844 plugin.
845 * Don't disable the mysql-plugin if connecting to the database fails
846 during initialization. Instead, try again in increasing intervals.
848 2006-07-19, Version 3.10.1
849 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
850 the apcups cannot be reached, unconnected sockets will pile up and
851 eventually lead to `Too many open files' errors.
853 2006-07-09, Version 3.10.0
854 * The `disk' plugin has been ported to Darwin.
855 * The `battery' plugin should work on many Apple computers now.
856 * The `traffic' plugin can now ignore certain interfaces. Also,
857 statistics for sent/received packets and errors have been added.
858 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
859 to Anthony Gialluca for contributing this plugin and providing me
860 with a test environment :)
861 * A plugin for monitoring an NTP instance and the local clock drift
862 has been added.
864 2006-06-25, Version 3.9.4
865 * The Solaris code in the `swap' plugin has been changed to reflect
866 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
867 working this out.
868 * The debugging system has been fixed to work with the Sun libc.
869 * When built without librrd the variable `operating_mode' could be
870 uninitialized. Thanks to David Elliot for reporting the bug.
872 2006-06-01, Version 3.9.3
873 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
874 operating systems also profit from the changes, but I wasn't able to
875 check that.
876 * Changed the build system to find the netinet-includes under FreeBSD
877 and therefore successfully build the `liboping' library there.
879 2006-05-09, Version 3.9.2
880 * Applied a patch to the `liboping' library. Due to a bug in the
881 sequence checking the `ping' plugin stopped working after
882 approximately 7.6 days.
884 2006-05-09, Version 3.8.5
885 * Applied a patch to the `liboping' library. Due to a bug in the
886 sequence checking the `ping' plugin stopped working after
887 approximately 7.6 days.
889 2006-04-21, Version 3.9.1
890 * Build issues with Solaris and possible other architectures have been
891 resolved.
892 * Problems when building the `apache'-plugin without `libcurl' have
893 been resolved.
894 * A bug in the `ping' plugin has been fixed. Sorry folks.
896 2006-04-02, Version 3.9.0
897 * A plugin to monitor the Apache webserver has been added.
898 <http://httpd.apache.org/>
899 * A plugin to collect statistics about virtual servers using VServer.
900 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
901 this plugin :)
902 * A plugin for wireless LAN cards has been added. It monitors signal
903 strength, link quality and noise ratio..
904 * A plugin for Apple hardware sensors has been added.
905 * An option to compile collectd with different `step' and `heartbeat'
906 settings has been added. The size of RRAs is no longer static but
907 calculated based on the settings for `step' and `width'.
908 * The `ping' plugin can now be configured to use a certain TTL.
909 * A plugin to monitor the hardware sensors of Apple computers has been
910 added.
911 * The plugins `cpu', `memory', `processes' and `traffic' have been
912 ported to Mach/Darwin (Mac OS X).
913 * The `log mode' has been contributed by Christophe Kalt. It writes
914 the data into text files rather than RRD files.
916 2006-04-09, Version 3.8.4
917 * Applied patch by Vincent Stehlé which improves the disk-name
918 resolution in the `hddtemp' plugin for Linux systems.
920 2006-04-02, Version 3.8.3
921 * Applied a patch by James Byers: The MySQL plugin was not working
922 with MySQL 5.0.2 or later.
924 2006-03-14, Version 3.8.2
925 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
926 the GNU libc, because it points to `/etc/fstab' rather than
927 `/etc/mtab'.
929 2006-03-13, Version 3.8.1
930 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
931 * Fixes in the debian `postinst' and `init.d' scripts.
933 2006-03-09, Version 3.8.0
934 * The `ping' plugin no longer uses `libping' but a self written
935 library named `liboping'. With this library it's possible to ping
936 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
938 2006-02-18, Version 3.7.2
939 * A simple bug in the `battery' plugin has been fixed. It should now
940 work with ACPI based batteries as well. Thanks to Sebastian for
941 fixing this.
942 * Fixing a bug that prevented collectd to be built without librrd.
943 Thanks to Werner Heuser for reporting it.
945 2006-02-04, Version 3.7.1
946 * The new network code has been improved to build with older versions
947 of glibc.
948 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
949 to Tommie Gannert for this patch.
951 2006-01-30, Version 3.7.0
952 * The `battery' plugin has been added. It collects information about
953 laptop batteries..
954 * The MySQL plugin has been improved: It now writes two more RRD
955 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
956 * The `cpufreq' plugin now reads another file since the file it did
957 read so far causes much overhead in the kernel. Also, you need root
958 to read the old file, but not to read the new one.
959 * The `hddtemp' plugin can now be configured to connect to another
960 address and/or port than localhost.
961 * The `df' plugin now prefers `statvfs' over `statfs'.
962 * The network code has been rewritten. collectd now supports unicast
963 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
964 be set in the configfile.
966 2006-01-24, Version 3.6.2
967 * Due to a bug in the configfile handling collectd wouldn't start in
968 client mode. This released fixes this.
970 2006-01-20, Version 3.6.1
971 * Due to a bug in `configure.in' all modules and the binary were
972 linked against `libmysqlclient'. This issue is solved by this
973 release.
975 2006-01-17, Version 3.6.0
976 * A config file has been added. This allows for loading only specific
977 plugins.
978 * A `df' plugin has been added.
979 * A `mysql' plugin has been added.
980 * The `ping' plugin doesn't entirely give up hope when a socket error
981 occurred, but will back of and increase the intervals between tries.
983 2006-01-21, Version 3.5.2
984 * Fixed yet another bug in the signal handling.. Stupid typo..
985 * Improved the ping plugin to not give up on socket errors (backport
986 from 3.6.0).
988 2005-12-18, Version 3.5.1
989 * The PID-file is now deleted correctly when shutting down the daemon.
990 * SIGINT and SIGTERM are now handled correctly.
992 2005-12-16, Version 3.5.0 (Revision 326)
993 * A bug in the `load' module under Solaris has been fixed.
994 * The `users' module has been contributed by Sebastian Harl. It counts
995 currently logged in users.
996 * The CPU module now works under FreeBSD without the use of
997 `libstatgrab', however SMP support is missing.
998 * The default directories for the RRD files and the PID file now
999 depend on the compile time setting of `localstatedir'.
1001 2005-11-15, Version 3.4.0 (Revision 236)
1002 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
1003 from gentoo's bugzilla for writing the patch.
1004 * The build dependency for librrd has been removed. Binaries built
1005 without librrd are client-only and will multicast their value as
1006 with the `-c' argument.
1007 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
1008 * The newly introduced `-f' switch prevents daemon initialization
1009 (forking, closing standard filehandles, etc.) Thanks to Alvaro
1010 Barcellos for this patch.
1012 2005-11-04, Version 3.3.0 (Revision 216)
1013 * New modules have been added:
1014 - `serial', for monitoring traffic on the serial interfaces
1015 - `nfs', for graphing NFS procedure calls
1016 - `tape', traffic from/to tape devices
1017 * The memory.rrd now accepts more than 4Gig of memory.
1019 2005-10-26, Version 3.2.0 (Revision 200)
1020 * Support for graphing the processes has been added (thanks to Lyonel
1021 Vincent)
1022 * If reading from hddtemp fails collectd will increase the time
1023 between polls up to one day.
1024 * The init.d files have been improved.
1025 * Problems with the spec file have been fixed.
1027 2005-10-16, Version 3.1.0 (Revision 194)
1028 * Added the `setsid' syscall to the startup code.
1029 * Support for hddtemp has been added (thanks to Vincent Stehlé)
1031 2005-09-30, Version 3.0.0 (Revision 184)
1032 * The ability to send/receive data to/from the network (think
1033 multicast) has been added.
1034 * Modules have been split up into shared libraries can be loaded at
1035 runtime. The biggest advantage is that the core program doesn't need
1036 to be linked against an external library.
1037 * A patch by George Kargiotakis has been applied: It fixes the sensors
1038 behaviour then more than one sensor is being queried.
1040 2005-09-16, Version 2.1.0 (Revision 172)
1041 * A module for swap statistics has been added.
1043 2005-09-09, Version 2.0.0 (Revision 135)
1044 * Filenames can no longer be configured at program startup. The only
1045 options as of this version are the directory and ping hosts.
1046 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
1047 Soft-IRQ statistics are added to `System'.
1048 * Diskstats now collect read and write bytes, not sectors.
1049 * Ping statistics can now be collected for more than one host. There
1050 is no default any more: If no host is given no host will be pinged.
1051 * A self-written patch for libping has been applied so it builds
1052 cleanly.
1054 2005-09-01, Version 1.8.1 (Revision 123)
1055 * Much improved configure-script: libraries and features may now be
1056 disabled.
1057 * More detailed warnings/error messages when RRD update fails.
1059 2005-08-29, Version 1.8.0:
1060 * Support for collecting disk statistics under Solaris.
1062 2005-08-25, Version 1.7.0:
1063 * Support for libstatgrab[1] for load, memory usage and network
1064 traffic. CPU- and disk-usage are not (yet) supported, since
1065 libstatgrab returns insufficient information. I will contact the
1066 authors.
1067 * Improved the CPU-initialization code for Solaris. Apparently CPUs
1068 aren't necessarily counted linear which is now handled correctly.
1069 [1]: http://www.i-scream.org/libstatgrab/
1071 2005-08-21, Version 1.6.0:
1072 * Basic support for Solaris: System load and cpu-usage can be
1073 collected under Solaris, too. Other stats will follow later.
1074 * Many fixes in the autoconf-script
1075 * Collection/Museum scripts have been added under contrib/museum
1076 * collectd may now be started in unprivileged mode, though ping
1077 statistics will not work.
1079 2005-07-17, Version 1.5.1:
1080 * Diskstats-RRDs now use major/minor for naming. Some systems have
1081 weird strings as disk-names..
1083 2005-07-17, Version 1.5:
1084 * A new module, diskstats, has been added. It collects information
1085 about the disks and partitions.
1087 2005-07-11, Version 1.4.2:
1088 * The meminfo module has been changed to work with more platforms
1089 and/or kernel versions.
1091 2005-07-10, Version 1.4.1: Correct traffic stats
1092 * The traffic rrd-file is now created with DS-type `COUNTER' which I
1093 forgot to correct when I changed that module.
1095 2005-07-09, Version 1.4: More traffic stats
1096 * Traffic is now collected for all interfaces that can be found
1097 * Temperature-statistics are read from lm-sensors if available
1099 2005-07-08, Version 1.3: CPU stats
1100 * Collecting CPU statistics now
1102 2005-07-12, Version 1.2: Using syslog
1103 * collectd is now using the syslog facility to report errors, warnings
1104 and the like..
1105 * The default directory is now /var/db/collectd
1107 2005-07-10, Version 1.1: Minor changes
1108 * Nothing really useful to say ;)
1110 2005-07-09, Version 1.0: Initial Version
1111 * The following modules are provided:
1112 * Load average
1113 * Ping time
1114 * Traffic
1115 * Memory info
