1 2009-01-02, Version 4.5.2
2 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
3 file may be in both locations, especially when the database was
4 installed in a non-standard path. Thanks to Dusty Doris for
6 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
7 Solaris, in the configure script automatically.
8 * build system, tcpconns plugin: Check for `kvm_nlist' and
9 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
10 library with similar functions to the BSD variant, but doesn't
11 provide these necessary functions.
12 * collectd.conf(5): Various fixes and clarifications.
13 * collectd: Remove a GNUism (unnamed unions), thus improving
15 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
16 This solves portability problems, especially for Solaris.
17 * dns plugin: Fix a portability problem with NetBSD.
18 * filecount plugin: Fix an off-by-one error. This error may cause a
20 * network plugin: Fix the handling of `type' in the network protocol.
21 Due to a programming mistake, only 4 or 8 bytes would be copied to a
22 much larger buffer. This caused the `type' to be transferred much
23 more often than necessary. In some cases, e. g. the `cpu' and
24 `cpufreq' plugins being used at the same time, data may be corrupted
25 in those files. Thanks to Bruno Prémont for debugging and reporting
27 * processes plugin: Fix a possible segmentation fault when specifying
28 invalid configuration options.
29 * unixsock plugin: Make sure the initialization function is run only
30 once. This resolves a file descriptor leak under systems which run
31 the initialization more than once, such as Solaris.
33 2008-10-16, Version 4.5.1
34 * build system: Change `--enable-<plugin>' to abort with an error if
35 dependencies are not met. Thanks to Bruno Prémont for the patch.
36 Also, the poisoning of various string functions has been restricted
38 * collectd: Fix a memory leak in the global value cache. With every
39 *missing* value a couple of bytes would be leaked. Another memory
40 leak in the configuration handling code has been fixed. Thanks to
41 Niraj Tolia for reporting these issues.
42 * collectd: Fix an off-by-one error in the ignorelist functionality.
43 When using regular expressions, the last character would be missing,
44 possibly matching differently from what one would expect.
45 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
47 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
48 Linzberger for reporting the bug.
49 * iptables plugin: Fix an off-by-one error. If a string was just one
50 character too long, it was truncated instead of reporting an error.
51 * network plugin: Fix a memory leak in the configuration handling
52 code. Thanks to Niraj Tolia for reporting this issue.
53 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
54 * postgresql plugin: Don't reopen connection during reinitialization.
55 This fixes a bug under Solaris and potentially other platforms.
56 Missing calls to `PQclear' have been added, too. This fixes memory
57 leaks. Thanks to ``Admin'' for reporting these bugs.
58 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
60 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
61 problems with some `libc's. Thanks to Matthias Lay for reporting the
64 2008-09-04, Version 4.5.0
65 * collectd: Added the ability to flush certain identifiers.
66 * collectd: The concept of `notification meta data' has been
68 * filecount plugin: The new filecount plugin counts the number of
69 files in a directory and its subdirectories.
70 * ipmi plugin: Sensor names have been changed to ensure unique names.
71 Notifications upon added and removed sensors can now be generated.
72 * notify_desktop plugin: This new plugin sends notifications to the
73 X desktop using the structure defined in the `Desktop Notification
75 * notify_email plugin: This new plugin sends out notifications via
76 email, using the `esmtp' library.
77 * onewire plugin: The new experimental(!) onewire plugin reads values,
78 such as temperatures, from sensors connected to the computer via the
80 * perl plugin: Improved synchronized access to internal data structures
81 and fixed a possible dead-lock.
82 * perl plugin: Added the ability to flush certain identifiers and marked
83 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
85 * perl plugin: Added the ability to configure Perl plugins.
86 * postgresql plugin: The new postgresql plugin collects statistics
87 about or from a PostgreSQL database.
88 * processes plugin: The `ProcessMatch' option has been added.
89 * rrdtool plugin: Implement throttling of the `update queue' to lessen
91 * tcpconns plugin: This plugin has been ported to OpenBSD.
92 * thermal plugin: The new thermal plugin collects system temperatures
93 using Linux ACPI thermal zone data.
95 2009-01-02, Version 4.4.5
96 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
97 file may be in both locations, especially when the database was
98 installed in a non-standard path. Thanks to Dusty Doris for
100 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
101 Solaris, in the configure script automatically.
102 * collectd.conf(5): Various fixes and clarifications.
103 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
104 portability problems, especially for Solaris.
105 * dns plugin: Fix a portability problem with NetBSD.
106 * network plugin: Fix the handling of `type' in the network protocol.
107 Due to a programming mistake, only 4 or 8 bytes would be copied to a
108 much larger buffer. This caused the `type' to be transferred much
109 more often than necessary. In some cases, e. g. the `cpu' and
110 `cpufreq' plugins being used at the same time, data may be corrupted
111 in those files. Thanks to Bruno Prémont for debugging and reporting
113 * unixsock plugin: Make sure the initialization function is run only
114 once. This resolves a file descriptor leak under systems which run
115 the initialization more than once, such as Solaris.
117 2008-10-16, Version 4.4.4
118 * build system: Change `--enable-<plugin>' to abort with an error if
119 dependencies are not met. Thanks to Bruno Prémont for the patch.
120 Also, the poisoning of various string functions has been restricted
122 * collectd: Fix a memory leak in the global value cache. With every
123 *missing* value a couple of bytes would be leaked. Another memory
124 leak in the configuration handling code has been fixed. Thanks to

134 code. Thanks to Niraj Tolia for reporting this issue.
135 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
136 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
137 problems with some `libc's. Thanks to Matthias Lay for reporting the
140 2008-09-01, Version 4.4.3
141 * collectd: Fix a memory leak in the threshold checking code.

149 * collectd: Try even harder to determine the endianess of the
150 architecture collectd is being built on.
151 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
153 * dns plugin: Fix compilation errors with BIND versions 19991001
155 * network plugin: Bugfix in the init routine: The init function
156 cleared a buffer regardless of its contents. This could lead to lost
157 values under Solaris.
158 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
159 * vserver plugin: Remove usage of the thread-unsafe `readdir'
161 * wireless plugin: Work around incorrect noise and power values
162 returned by some broken drivers.
164 2008-06-03, Version 4.4.1
165 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
166 to kyrone for reporting this.
167 * collectd: Fixed min/max output in notifications generated by
169 * collectd-nagios: Fix the protocol used to communicate with the
171 * perl plugin: Fail noisily, but don't shutdown the daemon, if
172 initialization has errors. An issue with Perl 5.10 has been fixed.
173 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
174 René Rebe and Siegmund Gorr for reporting this.
176 2008-05-06, Version 4.4.0
177 * collectd: Internal code cleanups.
178 * collectd: Added support for a `Flush' command in the unixsock and
179 exec plugins. This command can be used to force a plugin (or all) to
180 flush its values to disk.
181 * collectd: Thresholds can now be configured to apply to one data
182 source only, making it possible to configure different thresholds
183 for each data source.
184 * apache, nginx plugins: Added the possibility to disable host and/or
186 * ascent plugin: The new ascent plugin reads and parses the statistics
187 page of an Ascent server.
188 * cpu plugin: Support for the statgrab library has been added.
189 * disk plugin: The possibility to ignore certain disks or collect only
190 specific disks has been added.
191 * disk plugin: Support for the statgrab library has been added.
192 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
193 sensor values via IPMI, the intelligent platform management
195 * iptables plugin: The iptc library that is used by the iptables
196 plugin has been added to the distribution, because it is not
197 provided by all distributions and removed from at least one.
198 * powerdns plugin: The new powerdns plugin reads statistics from an
199 authoritative or a recursing PowerDNS name server.
200 * rrdtool plugin: The size of the files generated with the default
201 configuration has been decreased.
202 * tail plugin: The new tail plugin can be used to gather statistics by
203 continuously reading from log files.
204 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
205 TeamSpeak2 server and collects statistics about the number of users
206 and number of channels.
207 * users plugin: Support for the statgrab library has been added.
208 * vmem plugin: The new vmem plugin collects very detailed statistics
209 about the virtual memory subsystem of Linux.

229 2008-04-22, Version 4.3.3
230 * build system: Improved detection of several libraries, especially if
231 they are in non-standard paths.
232 * build system: Portability fixes: Automatically define "_REENTRANT"
233 if the libc expects it.
234 * collectd: Error and warning messages have been improved.
235 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
237 * apache plugin: Allocate new memory when reading a webpage instead of
238 using a buffer of static size.
239 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
241 * hddtemp plugin: Error and warning messages have been improved.
242 * sensors plugin: Fix sensor collection for some chip types.
244 2008-03-29, Version 4.3.2
245 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
246 `Persist' threshold options.

256 + Use `memcpy' when constructing/parsing a package to avoid
257 alignment problems on weird architectures, such as Sparc.
258 + Translate doubles to/from the x86 byte representation to ensure
259 cross-platform compatibility.
260 * ping plugin: Correct the handling of the `TTL' setting.
261 * swap plugin: Reapply a patch for Solaris.
262 * tcpconns plugin: Portability improvements.
264 2008-02-18, Version 4.3.0
265 * collectd: Notifications have been added to the daemon. Notifications
266 are status messages that may be associated with a data instance.
267 * collectd: Threshold checking has been added to the daemon. This
268 means that you can configure threshold values for each data
269 instance. If this threshold is exceeded a notification will be
271 * collectd: The new `FQDNLookup' option tells the daemon to use the
272 full qualified domain name as the hostname, not just the host part
273 es returned by `gethostname(2)'.
274 * collectd: Support for more than one `TypesDB' file has been added.
275 This is useful when one such file is included in a package but one
276 wants to add custom type definitions.
277 * collectd: The `Include' config option has been expanded to handle
278 entire directories and shell wildcards.
279 * collectdmon: The new `collectdmon' binary detects when collectd
280 terminates and automatically restarts it again.
281 * csv plugin: The CSV plugin is now able to store counter values as a
282 rate, using the `StoreRates' configuration option.
283 * exec plugin: Handling of notifications has been added and the
284 ability to pass arguments to the executed programs has been added.
285 * hddtemp plugin: The new `TranslateDevicename' option lets you
286 disable the translation from device names to major-minor-numbers.
287 * logfile plugin: Handling of notifications has been added.
288 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
289 domain name lookups in this plugin.
290 * perl plugin: Many internal changes added support for handling multiple
291 threads making the plugin reasonably usable inside collectd. The API has
292 been extended to support notifications and export global variables to
293 Perl plugins; callbacks now have to be identified by name rather than a
294 pointer to a subroutine. The plugin is no longer experimental.
295 * uuid plugin: The new UUID plugin sets the hostname to an unique
296 identifier for this host. This is meant for setups where each client
297 may migrate to another physical host, possibly going through one or
298 more name changes in the process. Thanks to Richard Jones from
299 Red Hat's Emerging Technology group for this plugin.
300 * libvirt: The new libvirt plugin uses the `libvirt' library to query
301 CPU, disk and network statistics about guest systems on the same
302 physical server. Thanks to Richard Jones from Red Hat's Emerging
303 Technology group for this plugin.
305 2008-04-22, Version 4.2.7
306 * build system: Improved detection of several libraries, especially if
307 they are in non-standard paths.
308 * build system: Portability fixes: Automatically define "_REENTRANT"
309 if the libc expects it.
310 * collectd: Error and warning messages have been improved.
311 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
313 * apache plugin: Allocate new memory when reading a webpage instead of
314 using a buffer of static size.
315 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
317 * hddtemp plugin: Error and warning messages have been improved.
318 * sensors plugin: Fix sensor collection for some chip types.

322 * sensors plugin: Fix temperature collection with libsensors4.
323 * unixsock plugin: Fix mixed input and output operation on streams.
324 * wireless plugin: Fix reading noise value.
326 2008-03-04, Version 4.2.5
327 * apache plugin: Improved initialization and error messages.
328 * exec plugin: Set supplementary group IDs.
330 + Create separate threads for reading from the socket and parsing
331 and dispatching incoming packets. Versions prior to this may have
332 problems in high-load situations, where the socket receive buffers
333 overflows, resulting in gaps in the data.
334 + Use `memcpy' when constructing/parsing a package to avoid
335 alignment problems on weird architectures, such as Sparc.
336 + Translate doubles to/from the x86 byte representation to ensure
337 cross-platform compatibility.
338 * ping plugin: Correct the handling of the `TTL' setting.
339 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
340 * swap plugin: Reapply a patch for Solaris.
341 * tcpconns plugin: Portability improvements.
343 2008-01-21, Version 4.2.4
344 * unixsock plugin: A bug in the unixsock plugin caused it not to set
345 the permission on the socket as documented in the manpage. Thanks to
346 Evgeny Chukreev for fixing this issue.
347 * collectd: The documentation has been improved.
349 2007-12-28, Version 4.2.3
350 * sensors plugin: Updated the plugin to build and work with version 3
351 of the libsensors library.
353 2007-12-15, Version 4.2.2
354 * nginx plugin: Incorrect comparison of strings lead to a segfault
355 when using the plugin. Thanks to Saulius Grigaliunas for fixing
357 * logfile plugin: The config option `Timestamp' was handled
358 incorrectly and basically always active. Thanks to Luke Heberling
361 2007-11-08, Version 4.2.1
362 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
364 * snmp plugin: Fix a memory leak.
366 2007-10-27, Version 4.2.0
367 * collectd: The new config option `Include' lets you include other
368 configfiles and thus split up your config into smaller parts. This
369 may be especially interesting for the snmp plugin to keep the data
370 definitions separate from the host definitions.
371 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
372 (number of connections, octets and packets for each service and
373 destination). Thanks to Sebastian Harl for this plugin.
374 * memcached plugin: The new `memcached' plugin connects to a memcached
375 daemon process and collects statistics of this distributed caching
376 system. Thanks to Antony Dovgal for contributing this plugin.
377 * nginx plugin: The new `nginx' plugin reads the status page of an
378 nginx daemon and saves the handled connections and requests.
379 * perl plugin: Many changes, including the added `EnableDebugger'
380 config option which lets you debug your Perl plugins more easily.
381 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
382 be more thread-safe otherwise by locking calls to the library.
383 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
384 correct the values returned by SNMP-agents. If a <data> block is
385 defined as `table' the instance is now optional. The sequence number
386 is used as the type-instance in this case. The new `InstancePrefix'
387 option allows to add arbitrary prefixes to the type-instance.
388 * tcpconns plugin: The new `tcpconns' plugin collects the number of
389 certain TCP connections and what state they're in. This can be used
390 to see how many connections your FTP server has to handle or how
391 many outgoing connections your mailserver has open.
393 2008-01-11, Version 4.1.6
394 * unixsock plugin: A bug in the unixsock plugin caused it not to set
395 the permission on the socket as documented in the manpage. Thanks to
396 Evgeny Chukreev for fixing this issue.
397 * collectd: The documentation has been improved.
399 2007-12-27, Version 4.1.5

403 of the libsensors library.
405 2007-11-08, Version 4.1.4
406 * Build system: Improve detection of the rrd library, especially if
407 it's in a non-standard location.
408 * Build system: A bug when parsing the argument for
409 `--with-libnetsnmp' has been fixed.
410 * collectd: Implement `strerror_r' if the libc doesn't provide it.
411 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
412 a deadlock or delay when shutting down the daemon.
413 * snmp plugin: Fix a memory leak.
415 2007-10-24, Version 4.1.3
416 * collectd: A build issue under Solaris has been resolved by renaming
418 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
419 be more thread-safe otherwise by locking calls to the library.
421 2007-09-28, Version 4.1.2
422 * apcups plugin: Fix reporting of the `load percent' data.
423 * wireless plugin: Correct the handling of cards returning signal and
424 noise quality as percentage.
425 * perl plugin: Fix a possible buffer overflow in get_module_name().
426 * build system: Further improve the detection of libraries.
427 * netlink plugin: Build issues under some older versions of the Linux
428 includes (i. e. Debian Sarge) have been fixed.
429 * snmp plugin: Fix a potential segfault when a host times out. Add
430 support for the `timeticks' type.
432 2007-09-12, Version 4.1.1
433 * Build system: The detection of `libnetlink' has been improved.
434 * collectd: The documentation has been fixed in numerous places.
435 * exec plugin: Setting the group under which to run a program has been
437 * collectd: The `sstrerror' function was improved to work correctly
438 with the broken GNU version of `strerror_r'.
439 * collectd: Write an error message to STDERR when loading of a plugin
441 * apcups plugin: Fix the `types' used to submit the values: They still
442 has an `apcups_' prefix which doesn't work anymore.
443 * rrdtool plugin: Create new RRD-files with the `begin' time set to
444 whatever the client thinks is `now'..
446 2007-09-01, Version 4.1.0
447 * Build system: The build system has been changed to automatically
448 disable all plugins, which are missing dependencies. The dependency
449 checking has been removed from the plugins themselves to remove
451 * Flexible interval: The interval of collected data is now sent along
452 with the data itself over the network, so that the interval-settings
453 of server and clients no longer needs to match.
454 * netlink plugin: The new `netlink' plugin connects to the Linux
455 kernel using a netlink socket and uses it to query information about
456 interfaces, qdiscs and classes.
457 * rrdtool plugin: The cache is now dumped to disk in an extra thread
458 to not block data collection.
459 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
460 network devices, such as switches, routers, thermometers, rack
461 monitoring servers, etc. The collectd-snmp(5) manpage documents this
463 * unixsock plugin: Added the `LISTVAL' command.
464 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
465 of music played with xmms.
467 2007-09-28, Version 4.0.9
468 * apcups plugin: Fix reporting of the `load percent' data.
469 * wireless plugin: Correct the handling of cards returning signal and
470 noise quality as percentage.
471 * perl plugin: Fix a possible buffer overflow in get_module_name().
473 2007-09-12, Version 4.0.8
474 * collectd: The `sstrerror' function was improved to work correctly
475 with the broken GNU version of `strerror_r'.
476 * collectd: Write an error message to STDERR when loading of a plugin
478 * apcups plugin: Fix the `types' used to submit the values: They still
479 has an `apcups_' prefix which doesn't work anymore.
480 * rrdtool plugin: Create new RRD-files with the `begin' time set to
481 whatever the client thinks is `now'..
483 2007-08-26, Version 4.0.7
484 * documentation: Some typos have been fixed and some information has
486 * build system: Many fixes for detecting libraries in unusual places,
487 such as on RedHat systems. The affected libraries are `libcurl',
488 `libmysql', and `libupsclient'.
489 * network plugin: Allow the `Port' option to be specified as a number
490 (i. e. without quotes).
491 * nut plugin: A fix allows linking the nut plugin against
492 libupsclient, version >= 2.2.0.
493 * processes plugin: Fix a potential segmentation fault.
495 2007-07-30, Version 4.0.6
496 * sensors plugin: Fix the ignorelist functionality: Only the `type
497 instance' was used to match against the list, but the documentation
498 told otherwise. This release fixes the code, so it complies with the
500 * syslog plugin: Call `openlog' right when the plugin is loaded, so
501 configuration messages will end up in the logging facility.
502 * conrtib/fedora: The contributed specfile for Fedora has been
505 2007-07-05, Version 4.0.5
506 * Portability: More fixes for OpenBSD have been included.
508 2007-06-24, Version 4.0.4
509 * cpu plugin: Fixed the Solaris code.
510 * dns plugin: Fixed a build issue for OpenBSD.
511 * interface plugin: Fixed the Solaris code.
512 * load plugin: Fixed the alternative `/proc' Linux code.
513 * memory plugin: Fixed the Solaris code.
514 * oconfig: Don't require `-lfl' anymore.
516 2007-06-19, Version 4.0.3
517 * cpu plugin: Fix the Darwin / Mac OS X code.
518 * ping plugin: Use the return value of `getpid', not its address.

525 they're given in numerically form.
527 2007-06-07, Version 4.0.1
528 * iptables plugin: A bug in the configuration routine has been fixed.
529 Setting a comment in the configfile will no longer cause a
532 2007-06-03, Version 4.0.0
533 * collectd: The plugin-infrastructure has been changed to allow for
534 more types of plugins, namely `write' and `log' plugins.
535 * collectd: The read-function has been changed to read many plugins in
536 parallel, using threads. Thus, plugins generally need to use
537 thread-safe functions from now on.
538 * collectd: The '-t' command line options allows to perform syntax tests
539 of the configuration file and exit immediately.
540 * csv plugin: The new `csv' plugin handles output to `comma separated
542 * rrdtool plugin: The new `rrdtool' plugin handles output to
543 RRD-files. Data can be cached to combine multiple updates into one
544 write to increase IO-performance.
545 * network plugin: The new `network' plugin handles IO via the network.
546 It implements a different, much more extensible protocol which can
547 combine many values in one packet, decreasing the number of UDP-
548 packets being sent. It can read from and send to the network and
549 with the appropriate configuration even forward packets to other
551 * unixsock plugin: The new `unixsock' plugin provides an interface to
552 communicate with the daemon while it is running. Right now the
553 commands `GETVAL' and `PUTVAL' are implemented, but more are to
555 * perl plugin: The new `perl' plugin allows you to write extensions
556 for collectd in the scripting-language Perl.
557 * logfile plugin: The new `logfile' plugin writes logmessages to files
559 * syslog plugin: The new `syslog' plugin sends logmessages to the
560 system's syslog daemon.
561 * entropy plugin: The new `entropy' plugin collects the amount of
562 entropy currently being available to the system.
563 * exec plugin: The new `exec' plugin forks child processes and reads
564 back values provided by the forked processes.
565 * iptables plugin: The new `iptables' plugin reads counters from
566 iptables rules. Thanks to Sjoerd van der Berg for contributing this
568 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
569 to Peter Holik for contributing this plugin.
570 * nut plugin: The new `nut' plugin connects the upsd of the `network
571 ups tools' and reads information about the connected UPS.
572 * apache plugin: Support for lighttpd's `BusyServers' (aka.
573 connections) field was added by Florent Monbillard.
574 * collectd-nagios: The new `collectd-nagios' binary queries values
575 from collectd, parses them and exits according to Nagios-standards.
576 * manpages: The manpages have been improved a lot.
578 2007-09-28, Version 3.11.7
579 * wireless plugin: Correct the handling of cards returning signal and
580 noise quality as percentage.
582 2007-08-31, Version 3.11.6
583 * processes plugin: Fix a potential segmentation fault.
585 2007-05-29, Version 3.11.5
586 * configure: Added `AC_SYS_LARGEFILE' for LFS.
587 * ntpd plugin: Fix a potential buffer overflow.
588 * processes plugin: Fix a bug when run under Linux 2.4. All processes
589 were accounted as `zombies'.
591 2007-04-10, Version 3.11.4
592 * dns plugin: Change the order of includes to make the plugin compile
595 2007-03-30, Version 3.11.3
596 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
597 of the unused `COLLECT_KSTAT'.
599 2007-02-11, Version 3.11.2
600 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
601 NULL-pointer may have been passed to `printf' which causes a
602 segfault with some libcs.
604 2007-02-10, Version 3.11.1
605 * df plugin: Some wrong defines have been fixed so the plugin works
607 * dns plugin: The usage of a struct has been fixed to work with
609 * processes plugin: Some missing defines have been added so the plugin
610 compiles cleanly under FreeBSD and presumably other UNIXes.
612 2006-12-22, Version 3.11.0
613 * collectd: The new command line option `-P' makes it easier for
614 distributors to change the location of PID-files.
615 * collectd: The daemon shuts down faster now which makes it easier to
616 write init.d-scripts for it.
617 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
618 caused problems every now and then.
619 * df plugin: New config options allow to ignore certain mountpoints,
620 filesystem types or devices.
621 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
622 and interprets it. It collects traffic as well as qtype, opcode and
624 * email plugin: Sebastian Harl has contributed this plugin which
625 counts received mails in categories (e. g. ham, spam, virus), spam
626 score (as given by SpamAssassin) and check types.
627 * mbmon plugin: Flavio Stanchina has contributed this plugin which
628 uses `mbmon' to gather information from sensors on the motherboard.
629 * processes plugin: Collect detailed statistics for configured
630 processes, that's process and thread count, CPU usage, resident
631 segment size and pagefaults.
632 * multimeter plugin: Peter Holik contributed a new plugin which
634 * sensors plugin: Lubos Stanek has put much effort into improving this
635 plugin, including `extended naming', collection of voltage values
636 and the possibility to ignore certain values.
638 2006-12-21, Version 3.10.4
639 * Max Kellermann has identified a bug in the server routine: When
640 opening a socket fails the daemon will (re)try opening the socket in
641 an endless loop, ultimately leading to a `EMFILE' error.
643 2006-11-04, Version 3.10.3
644 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
645 ntpd's reply was sent in more than one packet, the buffer size was
646 calculated incorrectly, resulting in the reading of uninitialized or
649 2006-11-01, Version 3.10.2
650 * The sample config file has been improved.
651 * Errors in the manpages have been corrected.
652 * The ping-plugin now adds hosts during initialization, not during
653 startup. This speeds up startup when no network connectivity is
654 available. Also, the hosts are being added later when the network is
656 * Improved BSD-support for the df-plugin.
657 * Fixed syntax errors in the swap-plugin for Mac OS X.
658 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
660 * Don't disable the mysql-plugin if connecting to the database fails
661 during initialization. Instead, try again in increasing intervals.
663 2006-07-19, Version 3.10.1
664 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
665 the apcups cannot be reached, unconnected sockets will pile up and
666 eventually lead to `Too many open files' errors.
668 2006-07-09, Version 3.10.0
669 * The `disk' plugin has been ported to Darwin.
670 * The `battery' plugin should work on many Apple computers now.
671 * The `traffic' plugin can now ignore certain interfaces. Also,
672 statistics for sent/received packets and errors have been added.
673 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
674 to Anthony Gialluca for contributing this plugin and providing me
675 with a test environment :)
676 * A plugin for monitoring an NTP instance and the local clock drift
679 2006-06-25, Version 3.9.4
680 * The Solaris code in the `swap' plugin has been changed to reflect
681 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
683 * The debugging system has been fixed to work with the Sun libc.
684 * When built without librrd the variable `operating_mode' could be
685 uninitialized. Thanks to David Elliot for reporting the bug.
687 2006-06-01, Version 3.9.3
688 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
689 operating systems also profit from the changes, but I wasn't able to
691 * Changed the build system to find the netinet-includes under FreeBSD
692 and therefore successfully build the `liboping' library there.
694 2006-05-09, Version 3.9.2
695 * Applied a patch to the `liboping' library. Due to a bug in the
696 sequence checking the `ping' plugin stopped working after
697 approximately 7.6 days.
699 2006-05-09, Version 3.8.5
700 * Applied a patch to the `liboping' library. Due to a bug in the
701 sequence checking the `ping' plugin stopped working after
702 approximately 7.6 days.
704 2006-04-21, Version 3.9.1
705 * Build issues with Solaris and possible other architectures have been
707 * Problems when building the `apache'-plugin without `libcurl' have
709 * A bug in the `ping' plugin has been fixed. Sorry folks.
711 2006-04-02, Version 3.9.0
712 * A plugin to monitor the Apache webserver has been added.
713 <http://httpd.apache.org/>
714 * A plugin to collect statistics about virtual servers using VServer.
715 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
717 * A plugin for wireless LAN cards has been added. It monitors signal
718 strength, link quality and noise ratio..
719 * A plugin for Apple hardware sensors has been added.
720 * An option to compile collectd with different `step' and `heartbeat'
721 settings has been added. The size of RRAs is no longer static but
722 calculated based on the settings for `step' and `width'.
723 * The `ping' plugin can now be configured to use a certain TTL.
724 * A plugin to monitor the hardware sensors of Apple computers has been
726 * The plugins `cpu', `memory', `processes' and `traffic' have been
727 ported to Mach/Darwin (Mac OS X).
728 * The `log mode' has been contributed by Christophe Kalt. It writes
729 the data into text files rather than RRD files.
731 2006-04-09, Version 3.8.4
732 * Applied patch by Vincent Stehlé which improves the disk-name
733 resolution in the `hddtemp' plugin for Linux systems.
735 2006-04-02, Version 3.8.3
736 * Applied a patch by James Byers: The MySQL plugin was not working
737 with MySQL 5.0.2 or later.
739 2006-03-14, Version 3.8.2
740 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
741 the GNU libc, because it points to `/etc/fstab' rather than
744 2006-03-13, Version 3.8.1
745 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
746 * Fixes in the debian `postinst' and `init.d' scripts.
748 2006-03-09, Version 3.8.0
749 * The `ping' plugin no longer uses `libping' but a self written
750 library named `liboping'. With this library it's possible to ping
751 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
753 2006-02-18, Version 3.7.2
754 * A simple bug in the `battery' plugin has been fixed. It should now
755 work with ACPI based batteries as well. Thanks to Sebastian for
757 * Fixing a bug that prevented collectd to be built without librrd.
758 Thanks to Werner Heuser for reporting it.
760 2006-02-04, Version 3.7.1
761 * The new network code has been improved to build with older versions
763 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
764 to Tommie Gannert for this patch.
766 2006-01-30, Version 3.7.0
767 * The `battery' plugin has been added. It collects information about
769 * The MySQL plugin has been improved: It now writes two more RRD
770 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
771 * The `cpufreq' plugin now reads another file since the file it did
772 read so far causes much overhead in the kernel. Also, you need root
773 to read the old file, but not to read the new one.
774 * The `hddtemp' plugin can now be configured to connect to another
775 address and/or port than localhost.
776 * The `df' plugin now prefers `statvfs' over `statfs'.
777 * The network code has been rewritten. collectd now supports unicast
778 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
779 be set in the configfile.
781 2006-01-24, Version 3.6.2
782 * Due to a bug in the configfile handling collectd wouldn't start in
783 client mode. This released fixes this.
785 2006-01-20, Version 3.6.1
786 * Due to a bug in `configure.in' all modules and the binary were
787 linked against `libmysqlclient'. This issue is solved by this
790 2006-01-17, Version 3.6.0
791 * A config file has been added. This allows for loading only specific
793 * A `df' plugin has been added.
794 * A `mysql' plugin has been added.
795 * The `ping' plugin doesn't entirely give up hope when a socket error
796 occurred, but will back of and increase the intervals between tries.
798 2006-01-21, Version 3.5.2
799 * Fixed yet another bug in the signal handling.. Stupid typo..
800 * Improved the ping plugin to not give up on socket errors (backport
803 2005-12-18, Version 3.5.1
804 * The PID-file is now deleted correctly when shutting down the daemon.
805 * SIGINT and SIGTERM are now handled correctly.
807 2005-12-16, Version 3.5.0 (Revision 326)
808 * A bug in the `load' module under Solaris has been fixed.
809 * The `users' module has been contributed by Sebastian Harl. It counts
810 currently logged in users.
811 * The CPU module now works under FreeBSD without the use of
812 `libstatgrab', however SMP support is missing.
813 * The default directories for the RRD files and the PID file now
814 depend on the compile time setting of `localstatedir'.
816 2005-11-15, Version 3.4.0 (Revision 236)
817 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
818 from gentoo's bugzilla for writing the patch.
819 * The build dependency for librrd has been removed. Binaries built
820 without librrd are client-only and will multicast their value as
821 with the `-c' argument.
822 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
823 * The newly introduced `-f' switch prevents daemon initialization
824 (forking, closing standard filehandles, etc.) Thanks to Alvaro
825 Barcellos for this patch.
827 2005-11-04, Version 3.3.0 (Revision 216)
828 * New modules have been added:
829 - `serial', for monitoring traffic on the serial interfaces
830 - `nfs', for graphing NFS procedure calls
831 - `tape', traffic from/to tape devices
832 * The memory.rrd now accepts more than 4Gig of memory.
834 2005-10-26, Version 3.2.0 (Revision 200)
835 * Support for graphing the processes has been added (thanks to Lyonel
837 * If reading from hddtemp fails collectd will increase the time
838 between polls up to one day.
839 * The init.d files have been improved.
840 * Problems with the spec file have been fixed.
842 2005-10-16, Version 3.1.0 (Revision 194)
843 * Added the `setsid' syscall to the startup code.
844 * Support for hddtemp has been added (thanks to Vincent Stehlé)
846 2005-09-30, Version 3.0.0 (Revision 184)
847 * The ability to send/receive data to/from the network (think
848 multicast) has been added.
849 * Modules have been split up into shared libraries can be loaded at
850 runtime. The biggest advantage is that the core program doesn't need
851 to be linked against an external library.
852 * A patch by George Kargiotakis has been applied: It fixes the sensors
853 behaviour then more than one sensor is being queried.
855 2005-09-16, Version 2.1.0 (Revision 172)
856 * A module for swap statistics has been added.
858 2005-09-09, Version 2.0.0 (Revision 135)
859 * Filenames can no longer be configured at program startup. The only
860 options as of this version are the directory and ping hosts.
861 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
862 Soft-IRQ statistics are added to `System'.
863 * Diskstats now collect read and write bytes, not sectors.
864 * Ping statistics can now be collected for more than one host. There
865 is no default any more: If no host is given no host will be pinged.
866 * A self-written patch for libping has been applied so it builds
869 2005-09-01, Version 1.8.1 (Revision 123)
870 * Much improved configure-script: libraries and features may now be
872 * More detailed warnings/error messages when RRD update fails.
874 2005-08-29, Version 1.8.0:
875 * Support for collecting disk statistics under Solaris.
877 2005-08-25, Version 1.7.0:
878 * Support for libstatgrab[1] for load, memory usage and network
879 traffic. CPU- and disk-usage are not (yet) supported, since
880 libstatgrab returns insufficient information. I will contact the
882 * Improved the CPU-initialization code for Solaris. Apparently CPUs
883 aren't necessarily counted linear which is now handled correctly.
884 [1]: http://www.i-scream.org/libstatgrab/
886 2005-08-21, Version 1.6.0:
887 * Basic support for Solaris: System load and cpu-usage can be
888 collected under Solaris, too. Other stats will follow later.
889 * Many fixes in the autoconf-script
890 * Collection/Museum scripts have been added under contrib/museum
891 * collectd may now be started in unprivileged mode, though ping
892 statistics will not work.
894 2005-07-17, Version 1.5.1:
895 * Diskstats-RRDs now use major/minor for naming. Some systems have
896 weird strings as disk-names..
898 2005-07-17, Version 1.5:
899 * A new module, diskstats, has been added. It collects information
900 about the disks and partitions.
902 2005-07-11, Version 1.4.2:
903 * The meminfo module has been changed to work with more platforms
904 and/or kernel versions.
906 2005-07-10, Version 1.4.1: Correct traffic stats
907 * The traffic rrd-file is now created with DS-type `COUNTER' which I
908 forgot to correct when I changed that module.
910 2005-07-09, Version 1.4: More traffic stats
911 * Traffic is now collected for all interfaces that can be found
912 * Temperature-statistics are read from lm-sensors if available
914 2005-07-08, Version 1.3: CPU stats
915 * Collecting CPU statistics now
917 2004-07-12, Version 1.2: Using syslog
918 * collectd is now using the syslog facility to report errors, warnings
920 * The default directory is now /var/db/collectd
922 2004-07-10, Version 1.1: Minor changes
923 * Nothing really useful to say ;)
925 2004-07-09, Version 1.0: Initial Version
926 * The following modules are provided:
projects / collectd.git / blob
