1 2008-10-16, Version 4.5.1
2 * build system: Change `--enable-<plugin>' to abort with an error if
3 dependencies are not met. Thanks to Bruno Prémont for the patch.
4 Also, the poisoning of various string functions has been restricted
6 * collectd: Fix a memory leak in the global value cache. With every
7 *missing* value a couple of bytes would be leaked. Another memory
8 leak in the configuration handling code has been fixed. Thanks to
9 Niraj Tolia for reporting these issues.
10 * collectd: Fix an off-by-one error in the ignorelist functionality.
11 When using regular expressions, the last character would be missing,
12 possibly matching differently from what one would expect.
13 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
15 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
16 Linzberger for reporting the bug.
17 * iptables plugin: Fix an off-by-one error. If a string was just one
18 character too long, it was truncated instead of reporting an error.
19 * network plugin: Fix a memory leak in the configuration handling
20 code. Thanks to Niraj Tolia for reporting this issue.
21 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
22 * postgresql plugin: Don't reopen connection during reinitialization.
23 This fixes a bug under Solaris and potentially other platforms.
24 Missing calls to `PQclear' have been added, too. This fixes memory
25 leaks. Thanks to ``Admin'' for reporting these bugs.
26 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
28 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
29 problems with some `libc's. Thanks to Matthias Lay for reporting the
32 2008-09-04, Version 4.5.0
33 * collectd: Added the ability to flush certain identifiers.
34 * collectd: The concept of `notification meta data' has been
36 * filecount plugin: The new filecount plugin counts the number of
37 files in a directory and its subdirectories.
38 * ipmi plugin: Sensor names have been changed to ensure unique names.
39 Notifications upon added and removed sensors can now be generated.
40 * notify_desktop plugin: This new plugin sends notifications to the
41 X desktop using the structure defined in the `Desktop Notification
43 * notify_email plugin: This new plugin sends out notifications via
44 email, using the `esmtp' library.
45 * onewire plugin: The new experimental(!) onewire plugin reads values,
46 such as temperatures, from sensors connected to the computer via the
48 * perl plugin: Improved synchronized access to internal data structures
49 and fixed a possible dead-lock.
50 * perl plugin: Added the ability to flush certain identifiers and marked
51 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
53 * perl plugin: Added the ability to configure Perl plugins.
54 * postgresql plugin: The new postgresql plugin collects statistics
55 about or from a PostgreSQL database.
56 * processes plugin: The `ProcessMatch' option has been added.
57 * rrdtool plugin: Implement throttling of the `update queue' to lessen
59 * tcpconns plugin: This plugin has been ported to OpenBSD.
60 * thermal plugin: The new thermal plugin collects system temperatures
61 using Linux ACPI thermal zone data.
63 2009-01-02, Version 4.4.5
64 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
65 file may be in both locations, especially when the database was
66 installed in a non-standard path. Thanks to Dusty Doris for
68 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
69 Solaris, in the configure script automatically.
70 * collectd.conf(5): Various fixes and clarifications.
71 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
72 portability problems, especially for Solaris.
73 * dns plugin: Fix a portability problem with NetBSD.
74 * network plugin: Fix the handling of `type' in the network protocol.
75 Due to a programming mistake, only 4 or 8 bytes would be copied to a
76 much larger buffer. This caused the `type' to be transferred much
77 more often than necessary. In some cases, e. g. the `cpu' and
78 `cpufreq' plugins being used at the same time, data may be corrupted
79 in those files. Thanks to Bruno Prémont for debugging and reporting
81 * unixsock plugin: Make sure the initialization function is run only
82 once. This resolves a file descriptor leak under systems which run
83 the initialization more than once, such as Solaris.
85 2008-10-16, Version 4.4.4
86 * build system: Change `--enable-<plugin>' to abort with an error if
87 dependencies are not met. Thanks to Bruno Prémont for the patch.
88 Also, the poisoning of various string functions has been restricted
90 * collectd: Fix a memory leak in the global value cache. With every
91 *missing* value a couple of bytes would be leaked. Another memory
92 leak in the configuration handling code has been fixed. Thanks to
93 Niraj Tolia for reporting these issues.
94 * collectd: Fix an off-by-one error in the ignorelist functionality.
95 When using regular expressions, the last character would be missing,
96 possibly matching differently from what one would expect.
97 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
99 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
100 Linzberger for reporting the bug.
101 * network plugin: Fix a memory leak in the configuration handling
102 code. Thanks to Niraj Tolia for reporting this issue.
103 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
104 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
105 problems with some `libc's. Thanks to Matthias Lay for reporting the
108 2008-09-01, Version 4.4.3
109 * collectd: Fix a memory leak in the threshold checking code.
110 * memcached plugin: Fix a too short timeout and a related file
112 * memory plugin: A typo in the libstatgrab code has been fixed.
113 * snmp plugin: Fix a possible memory leak.
115 2008-07-15, Version 4.4.2
116 * build system: Use pkg-config to detect the upsclient library.
117 * collectd: Try even harder to determine the endianess of the
118 architecture collectd is being built on.
119 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
121 * dns plugin: Fix compilation errors with BIND versions 19991001
123 * network plugin: Bugfix in the init routine: The init function
124 cleared a buffer regardless of its contents. This could lead to lost
125 values under Solaris.
126 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
127 * vserver plugin: Remove usage of the thread-unsafe `readdir'
129 * wireless plugin: Work around incorrect noise and power values
130 returned by some broken drivers.
132 2008-06-03, Version 4.4.1
133 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
134 to kyrone for reporting this.
135 * collectd: Fixed min/max output in notifications generated by
137 * collectd-nagios: Fix the protocol used to communicate with the
139 * perl plugin: Fail noisily, but don't shutdown the daemon, if
140 initialization has errors. An issue with Perl 5.10 has been fixed.
141 * teamspeak2 plugin: Fixed an out of bound array access. Thanks to
142 René Rebe and Siegmund Gorr for reporting this.
144 2008-05-06, Version 4.4.0
145 * collectd: Internal code cleanups.
146 * collectd: Added support for a `Flush' command in the unixsock and
147 exec plugins. This command can be used to force a plugin (or all) to
148 flush its values to disk.
149 * collectd: Thresholds can now be configured to apply to one data
150 source only, making it possible to configure different thresholds
151 for each data source.
152 * apache, nginx plugins: Added the possibility to disable host and/or
154 * ascent plugin: The new ascent plugin reads and parses the statistics
155 page of an Ascent server.
156 * cpu plugin: Support for the statgrab library has been added.
157 * disk plugin: The possibility to ignore certain disks or collect only
158 specific disks has been added.
159 * disk plugin: Support for the statgrab library has been added.
160 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
161 sensor values via IPMI, the intelligent platform management
163 * iptables plugin: The iptc library that is used by the iptables
164 plugin has been added to the distribution, because it is not
165 provided by all distributions and removed from at least one.
166 * powerdns plugin: The new powerdns plugin reads statistics from an
167 authoritative or a recursing PowerDNS name server.
168 * rrdtool plugin: The size of the files generated with the default
169 configuration has been decreased.
170 * tail plugin: The new tail plugin can be used to gather statistics by
171 continuously reading from log files.
172 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
173 TeamSpeak2 server and collects statistics about the number of users
174 and number of channels.
175 * users plugin: Support for the statgrab library has been added.
176 * vmem plugin: The new vmem plugin collects very detailed statistics
177 about the virtual memory subsystem of Linux.
179 2008-08-30, Version 4.3.4
180 * Build system: Improved detection of and linking with the statgrab
182 * collectd: Portability fixes, especially to determine endianess more
184 * Various plugins: Fix format strings.

193 * vserver plugin: A thread-unsafe function has been replaced.
194 * wireless plugin: A work-around for broken wireless drivers has been
197 2008-04-22, Version 4.3.3
198 * build system: Improved detection of several libraries, especially if
199 they are in non-standard paths.
200 * build system: Portability fixes: Automatically define "_REENTRANT"
201 if the libc expects it.
202 * collectd: Error and warning messages have been improved.
203 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
205 * apache plugin: Allocate new memory when reading a webpage instead of
206 using a buffer of static size.
207 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
209 * hddtemp plugin: Error and warning messages have been improved.
210 * sensors plugin: Fix sensor collection for some chip types.
212 2008-03-29, Version 4.3.2
213 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
214 `Persist' threshold options.
215 * collectd: Fix handling of missing values in the global value cache.
216 * collectd: Improved error messages when parsing the configuration.

221 2008-03-05, Version 4.3.1
222 * exec plugin: Set supplementary group IDs.
224 + Use `memcpy' when constructing/parsing a package to avoid
225 alignment problems on weird architectures, such as Sparc.
226 + Translate doubles to/from the x86 byte representation to ensure
227 cross-platform compatibility.
228 * ping plugin: Correct the handling of the `TTL' setting.
229 * swap plugin: Reapply a patch for Solaris.
230 * tcpconns plugin: Portability improvements.
232 2008-02-18, Version 4.3.0
233 * collectd: Notifications have been added to the daemon. Notifications
234 are status messages that may be associated with a data instance.
235 * collectd: Threshold checking has been added to the daemon. This
236 means that you can configure threshold values for each data
237 instance. If this threshold is exceeded a notification will be
239 * collectd: The new `FQDNLookup' option tells the daemon to use the
240 full qualified domain name as the hostname, not just the host part
241 es returned by `gethostname(2)'.
242 * collectd: Support for more than one `TypesDB' file has been added.
243 This is useful when one such file is included in a package but one
244 wants to add custom type definitions.
245 * collectd: The `Include' config option has been expanded to handle
246 entire directories and shell wildcards.
247 * collectdmon: The new `collectdmon' binary detects when collectd
248 terminates and automatically restarts it again.
249 * csv plugin: The CSV plugin is now able to store counter values as a
250 rate, using the `StoreRates' configuration option.
251 * exec plugin: Handling of notifications has been added and the
252 ability to pass arguments to the executed programs has been added.
253 * hddtemp plugin: The new `TranslateDevicename' option lets you
254 disable the translation from device names to major-minor-numbers.
255 * logfile plugin: Handling of notifications has been added.
256 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
257 domain name lookups in this plugin.
258 * perl plugin: Many internal changes added support for handling multiple
259 threads making the plugin reasonably usable inside collectd. The API has
260 been extended to support notifications and export global variables to
261 Perl plugins; callbacks now have to be identified by name rather than a
262 pointer to a subroutine. The plugin is no longer experimental.
263 * uuid plugin: The new UUID plugin sets the hostname to an unique
264 identifier for this host. This is meant for setups where each client
265 may migrate to another physical host, possibly going through one or
266 more name changes in the process. Thanks to Richard Jones from
267 Red Hat's Emerging Technology group for this plugin.
268 * libvirt: The new libvirt plugin uses the `libvirt' library to query
269 CPU, disk and network statistics about guest systems on the same
270 physical server. Thanks to Richard Jones from Red Hat's Emerging
271 Technology group for this plugin.
273 2008-04-22, Version 4.2.7
274 * build system: Improved detection of several libraries, especially if
275 they are in non-standard paths.
276 * build system: Portability fixes: Automatically define "_REENTRANT"
277 if the libc expects it.
278 * collectd: Error and warning messages have been improved.
279 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
281 * apache plugin: Allocate new memory when reading a webpage instead of
282 using a buffer of static size.
283 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
285 * hddtemp plugin: Error and warning messages have been improved.
286 * sensors plugin: Fix sensor collection for some chip types.
288 2008-03-29, Version 4.2.6
289 * collectd: Improved error messages when parsing the configuration.
290 * sensors plugin: Fix temperature collection with libsensors4.
291 * unixsock plugin: Fix mixed input and output operation on streams.
292 * wireless plugin: Fix reading noise value.
294 2008-03-04, Version 4.2.5
295 * apache plugin: Improved initialization and error messages.
296 * exec plugin: Set supplementary group IDs.
298 + Create separate threads for reading from the socket and parsing
299 and dispatching incoming packets. Versions prior to this may have
300 problems in high-load situations, where the socket receive buffers
301 overflows, resulting in gaps in the data.
302 + Use `memcpy' when constructing/parsing a package to avoid
303 alignment problems on weird architectures, such as Sparc.
304 + Translate doubles to/from the x86 byte representation to ensure
305 cross-platform compatibility.
306 * ping plugin: Correct the handling of the `TTL' setting.
307 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
308 * swap plugin: Reapply a patch for Solaris.
309 * tcpconns plugin: Portability improvements.
311 2008-01-21, Version 4.2.4
312 * unixsock plugin: A bug in the unixsock plugin caused it not to set
313 the permission on the socket as documented in the manpage. Thanks to
314 Evgeny Chukreev for fixing this issue.
315 * collectd: The documentation has been improved.
317 2007-12-28, Version 4.2.3
318 * sensors plugin: Updated the plugin to build and work with version 3
319 of the libsensors library.
321 2007-12-15, Version 4.2.2
322 * nginx plugin: Incorrect comparison of strings lead to a segfault
323 when using the plugin. Thanks to Saulius Grigaliunas for fixing
325 * logfile plugin: The config option `Timestamp' was handled
326 incorrectly and basically always active. Thanks to Luke Heberling
329 2007-11-08, Version 4.2.1
330 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
332 * snmp plugin: Fix a memory leak.
334 2007-10-27, Version 4.2.0
335 * collectd: The new config option `Include' lets you include other
336 configfiles and thus split up your config into smaller parts. This
337 may be especially interesting for the snmp plugin to keep the data
338 definitions separate from the host definitions.
339 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
340 (number of connections, octets and packets for each service and
341 destination). Thanks to Sebastian Harl for this plugin.
342 * memcached plugin: The new `memcached' plugin connects to a memcached
343 daemon process and collects statistics of this distributed caching
344 system. Thanks to Antony Dovgal for contributing this plugin.
345 * nginx plugin: The new `nginx' plugin reads the status page of an
346 nginx daemon and saves the handled connections and requests.
347 * perl plugin: Many changes, including the added `EnableDebugger'
348 config option which lets you debug your Perl plugins more easily.
349 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
350 be more thread-safe otherwise by locking calls to the library.
351 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
352 correct the values returned by SNMP-agents. If a <data> block is
353 defined as `table' the instance is now optional. The sequence number
354 is used as the type-instance in this case. The new `InstancePrefix'
355 option allows to add arbitrary prefixes to the type-instance.
356 * tcpconns plugin: The new `tcpconns' plugin collects the number of
357 certain TCP connections and what state they're in. This can be used
358 to see how many connections your FTP server has to handle or how
359 many outgoing connections your mailserver has open.
361 2008-01-11, Version 4.1.6
362 * unixsock plugin: A bug in the unixsock plugin caused it not to set
363 the permission on the socket as documented in the manpage. Thanks to
364 Evgeny Chukreev for fixing this issue.

371 of the libsensors library.
373 2007-11-08, Version 4.1.4
374 * Build system: Improve detection of the rrd library, especially if
375 it's in a non-standard location.
376 * Build system: A bug when parsing the argument for
377 `--with-libnetsnmp' has been fixed.
378 * collectd: Implement `strerror_r' if the libc doesn't provide it.
379 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
380 a deadlock or delay when shutting down the daemon.
381 * snmp plugin: Fix a memory leak.
383 2007-10-24, Version 4.1.3
384 * collectd: A build issue under Solaris has been resolved by renaming
386 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
387 be more thread-safe otherwise by locking calls to the library.
389 2007-09-28, Version 4.1.2
390 * apcups plugin: Fix reporting of the `load percent' data.
391 * wireless plugin: Correct the handling of cards returning signal and
392 noise quality as percentage.
393 * perl plugin: Fix a possible buffer overflow in get_module_name().
394 * build system: Further improve the detection of libraries.
395 * netlink plugin: Build issues under some older versions of the Linux
396 includes (i. e. Debian Sarge) have been fixed.

398 support for the `timeticks' type.
400 2007-09-12, Version 4.1.1
401 * Build system: The detection of `libnetlink' has been improved.
402 * collectd: The documentation has been fixed in numerous places.
403 * exec plugin: Setting the group under which to run a program has been
405 * collectd: The `sstrerror' function was improved to work correctly
406 with the broken GNU version of `strerror_r'.
407 * collectd: Write an error message to STDERR when loading of a plugin
409 * apcups plugin: Fix the `types' used to submit the values: They still
410 has an `apcups_' prefix which doesn't work anymore.
411 * rrdtool plugin: Create new RRD-files with the `begin' time set to
412 whatever the client thinks is `now'..
414 2007-09-01, Version 4.1.0
415 * Build system: The build system has been changed to automatically
416 disable all plugins, which are missing dependencies. The dependency
417 checking has been removed from the plugins themselves to remove
419 * Flexible interval: The interval of collected data is now sent along
420 with the data itself over the network, so that the interval-settings
421 of server and clients no longer needs to match.
422 * netlink plugin: The new `netlink' plugin connects to the Linux
423 kernel using a netlink socket and uses it to query information about
424 interfaces, qdiscs and classes.
425 * rrdtool plugin: The cache is now dumped to disk in an extra thread
426 to not block data collection.
427 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
428 network devices, such as switches, routers, thermometers, rack
429 monitoring servers, etc. The collectd-snmp(5) manpage documents this
431 * unixsock plugin: Added the `LISTVAL' command.
432 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
433 of music played with xmms.
435 2007-09-28, Version 4.0.9
436 * apcups plugin: Fix reporting of the `load percent' data.
437 * wireless plugin: Correct the handling of cards returning signal and
438 noise quality as percentage.
439 * perl plugin: Fix a possible buffer overflow in get_module_name().
441 2007-09-12, Version 4.0.8
442 * collectd: The `sstrerror' function was improved to work correctly
443 with the broken GNU version of `strerror_r'.
444 * collectd: Write an error message to STDERR when loading of a plugin
446 * apcups plugin: Fix the `types' used to submit the values: They still
447 has an `apcups_' prefix which doesn't work anymore.
448 * rrdtool plugin: Create new RRD-files with the `begin' time set to
449 whatever the client thinks is `now'..
451 2007-08-26, Version 4.0.7
452 * documentation: Some typos have been fixed and some information has
454 * build system: Many fixes for detecting libraries in unusual places,
455 such as on RedHat systems. The affected libraries are `libcurl',
456 `libmysql', and `libupsclient'.
457 * network plugin: Allow the `Port' option to be specified as a number
458 (i. e. without quotes).
459 * nut plugin: A fix allows linking the nut plugin against
460 libupsclient, version >= 2.2.0.
461 * processes plugin: Fix a potential segmentation fault.
463 2007-07-30, Version 4.0.6
464 * sensors plugin: Fix the ignorelist functionality: Only the `type
465 instance' was used to match against the list, but the documentation
466 told otherwise. This release fixes the code, so it complies with the
468 * syslog plugin: Call `openlog' right when the plugin is loaded, so
469 configuration messages will end up in the logging facility.
470 * conrtib/fedora: The contributed specfile for Fedora has been
473 2007-07-05, Version 4.0.5
474 * Portability: More fixes for OpenBSD have been included.
476 2007-06-24, Version 4.0.4
477 * cpu plugin: Fixed the Solaris code.
478 * dns plugin: Fixed a build issue for OpenBSD.
479 * interface plugin: Fixed the Solaris code.
480 * load plugin: Fixed the alternative `/proc' Linux code.

482 * oconfig: Don't require `-lfl' anymore.
484 2007-06-19, Version 4.0.3
485 * cpu plugin: Fix the Darwin / Mac OS X code.
486 * ping plugin: Use the return value of `getpid', not its address.
487 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
488 initialized correctly.
489 * configure: Added `--with-nan-emulation' to aid cross compilation.
491 2007-06-12, Version 4.0.2
492 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
493 they're given in numerically form.
495 2007-06-07, Version 4.0.1
496 * iptables plugin: A bug in the configuration routine has been fixed.
497 Setting a comment in the configfile will no longer cause a
500 2007-06-03, Version 4.0.0
501 * collectd: The plugin-infrastructure has been changed to allow for
502 more types of plugins, namely `write' and `log' plugins.
503 * collectd: The read-function has been changed to read many plugins in
504 parallel, using threads. Thus, plugins generally need to use
505 thread-safe functions from now on.
506 * collectd: The '-t' command line options allows to perform syntax tests
507 of the configuration file and exit immediately.
508 * csv plugin: The new `csv' plugin handles output to `comma separated
510 * rrdtool plugin: The new `rrdtool' plugin handles output to
511 RRD-files. Data can be cached to combine multiple updates into one
512 write to increase IO-performance.
513 * network plugin: The new `network' plugin handles IO via the network.
514 It implements a different, much more extensible protocol which can
515 combine many values in one packet, decreasing the number of UDP-
516 packets being sent. It can read from and send to the network and
517 with the appropriate configuration even forward packets to other
519 * unixsock plugin: The new `unixsock' plugin provides an interface to
520 communicate with the daemon while it is running. Right now the
521 commands `GETVAL' and `PUTVAL' are implemented, but more are to
523 * perl plugin: The new `perl' plugin allows you to write extensions
524 for collectd in the scripting-language Perl.
525 * logfile plugin: The new `logfile' plugin writes logmessages to files
527 * syslog plugin: The new `syslog' plugin sends logmessages to the
528 system's syslog daemon.
529 * entropy plugin: The new `entropy' plugin collects the amount of
530 entropy currently being available to the system.
531 * exec plugin: The new `exec' plugin forks child processes and reads
532 back values provided by the forked processes.
533 * iptables plugin: The new `iptables' plugin reads counters from
534 iptables rules. Thanks to Sjoerd van der Berg for contributing this
536 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
537 to Peter Holik for contributing this plugin.
538 * nut plugin: The new `nut' plugin connects the upsd of the `network
539 ups tools' and reads information about the connected UPS.
540 * apache plugin: Support for lighttpd's `BusyServers' (aka.
541 connections) field was added by Florent Monbillard.
542 * collectd-nagios: The new `collectd-nagios' binary queries values
543 from collectd, parses them and exits according to Nagios-standards.
544 * manpages: The manpages have been improved a lot.
546 2007-09-28, Version 3.11.7
547 * wireless plugin: Correct the handling of cards returning signal and
548 noise quality as percentage.
550 2007-08-31, Version 3.11.6
551 * processes plugin: Fix a potential segmentation fault.
553 2007-05-29, Version 3.11.5
554 * configure: Added `AC_SYS_LARGEFILE' for LFS.
555 * ntpd plugin: Fix a potential buffer overflow.
556 * processes plugin: Fix a bug when run under Linux 2.4. All processes
557 were accounted as `zombies'.
559 2007-04-10, Version 3.11.4
560 * dns plugin: Change the order of includes to make the plugin compile
563 2007-03-30, Version 3.11.3
564 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
565 of the unused `COLLECT_KSTAT'.
567 2007-02-11, Version 3.11.2
568 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
569 NULL-pointer may have been passed to `printf' which causes a
570 segfault with some libcs.
572 2007-02-10, Version 3.11.1
573 * df plugin: Some wrong defines have been fixed so the plugin works
575 * dns plugin: The usage of a struct has been fixed to work with
577 * processes plugin: Some missing defines have been added so the plugin
578 compiles cleanly under FreeBSD and presumably other UNIXes.
580 2006-12-22, Version 3.11.0
581 * collectd: The new command line option `-P' makes it easier for
582 distributors to change the location of PID-files.
583 * collectd: The daemon shuts down faster now which makes it easier to
584 write init.d-scripts for it.
585 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
586 caused problems every now and then.
587 * df plugin: New config options allow to ignore certain mountpoints,
588 filesystem types or devices.
589 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
590 and interprets it. It collects traffic as well as qtype, opcode and
592 * email plugin: Sebastian Harl has contributed this plugin which
593 counts received mails in categories (e. g. ham, spam, virus), spam
594 score (as given by SpamAssassin) and check types.
595 * mbmon plugin: Flavio Stanchina has contributed this plugin which
596 uses `mbmon' to gather information from sensors on the motherboard.
597 * processes plugin: Collect detailed statistics for configured
598 processes, that's process and thread count, CPU usage, resident
599 segment size and pagefaults.
600 * multimeter plugin: Peter Holik contributed a new plugin which
602 * sensors plugin: Lubos Stanek has put much effort into improving this
603 plugin, including `extended naming', collection of voltage values
604 and the possibility to ignore certain values.
606 2006-12-21, Version 3.10.4
607 * Max Kellermann has identified a bug in the server routine: When
608 opening a socket fails the daemon will (re)try opening the socket in
609 an endless loop, ultimately leading to a `EMFILE' error.
611 2006-11-04, Version 3.10.3
612 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
613 ntpd's reply was sent in more than one packet, the buffer size was
614 calculated incorrectly, resulting in the reading of uninitialized or
617 2006-11-01, Version 3.10.2
618 * The sample config file has been improved.
619 * Errors in the manpages have been corrected.
620 * The ping-plugin now adds hosts during initialization, not during
621 startup. This speeds up startup when no network connectivity is
622 available. Also, the hosts are being added later when the network is
624 * Improved BSD-support for the df-plugin.
625 * Fixed syntax errors in the swap-plugin for Mac OS X.
626 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
628 * Don't disable the mysql-plugin if connecting to the database fails
629 during initialization. Instead, try again in increasing intervals.
631 2006-07-19, Version 3.10.1
632 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
633 the apcups cannot be reached, unconnected sockets will pile up and
634 eventually lead to `Too many open files' errors.
636 2006-07-09, Version 3.10.0
637 * The `disk' plugin has been ported to Darwin.
638 * The `battery' plugin should work on many Apple computers now.
639 * The `traffic' plugin can now ignore certain interfaces. Also,
640 statistics for sent/received packets and errors have been added.
641 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
642 to Anthony Gialluca for contributing this plugin and providing me
643 with a test environment :)
644 * A plugin for monitoring an NTP instance and the local clock drift
647 2006-06-25, Version 3.9.4
648 * The Solaris code in the `swap' plugin has been changed to reflect
649 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
651 * The debugging system has been fixed to work with the Sun libc.
652 * When built without librrd the variable `operating_mode' could be
653 uninitialized. Thanks to David Elliot for reporting the bug.
655 2006-06-01, Version 3.9.3
656 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
657 operating systems also profit from the changes, but I wasn't able to
659 * Changed the build system to find the netinet-includes under FreeBSD
660 and therefore successfully build the `liboping' library there.
662 2006-05-09, Version 3.9.2
663 * Applied a patch to the `liboping' library. Due to a bug in the
664 sequence checking the `ping' plugin stopped working after
665 approximately 7.6 days.
667 2006-05-09, Version 3.8.5
668 * Applied a patch to the `liboping' library. Due to a bug in the
669 sequence checking the `ping' plugin stopped working after
670 approximately 7.6 days.
672 2006-04-21, Version 3.9.1
673 * Build issues with Solaris and possible other architectures have been
675 * Problems when building the `apache'-plugin without `libcurl' have
677 * A bug in the `ping' plugin has been fixed. Sorry folks.
679 2006-04-02, Version 3.9.0
680 * A plugin to monitor the Apache webserver has been added.
681 <http://httpd.apache.org/>
682 * A plugin to collect statistics about virtual servers using VServer.
683 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
685 * A plugin for wireless LAN cards has been added. It monitors signal
686 strength, link quality and noise ratio..
687 * A plugin for Apple hardware sensors has been added.
688 * An option to compile collectd with different `step' and `heartbeat'
689 settings has been added. The size of RRAs is no longer static but
690 calculated based on the settings for `step' and `width'.
691 * The `ping' plugin can now be configured to use a certain TTL.
692 * A plugin to monitor the hardware sensors of Apple computers has been
694 * The plugins `cpu', `memory', `processes' and `traffic' have been
695 ported to Mach/Darwin (Mac OS X).
696 * The `log mode' has been contributed by Christophe Kalt. It writes
697 the data into text files rather than RRD files.
699 2006-04-09, Version 3.8.4
700 * Applied patch by Vincent Stehlé which improves the disk-name
701 resolution in the `hddtemp' plugin for Linux systems.
703 2006-04-02, Version 3.8.3
704 * Applied a patch by James Byers: The MySQL plugin was not working
705 with MySQL 5.0.2 or later.
707 2006-03-14, Version 3.8.2
708 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
709 the GNU libc, because it points to `/etc/fstab' rather than
712 2006-03-13, Version 3.8.1
713 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
714 * Fixes in the debian `postinst' and `init.d' scripts.
716 2006-03-09, Version 3.8.0
717 * The `ping' plugin no longer uses `libping' but a self written
718 library named `liboping'. With this library it's possible to ping
719 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
721 2006-02-18, Version 3.7.2
722 * A simple bug in the `battery' plugin has been fixed. It should now
723 work with ACPI based batteries as well. Thanks to Sebastian for
725 * Fixing a bug that prevented collectd to be built without librrd.
726 Thanks to Werner Heuser for reporting it.
728 2006-02-04, Version 3.7.1
729 * The new network code has been improved to build with older versions
731 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
732 to Tommie Gannert for this patch.
734 2006-01-30, Version 3.7.0
735 * The `battery' plugin has been added. It collects information about
737 * The MySQL plugin has been improved: It now writes two more RRD
738 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
739 * The `cpufreq' plugin now reads another file since the file it did
740 read so far causes much overhead in the kernel. Also, you need root
741 to read the old file, but not to read the new one.
742 * The `hddtemp' plugin can now be configured to connect to another
743 address and/or port than localhost.
744 * The `df' plugin now prefers `statvfs' over `statfs'.
745 * The network code has been rewritten. collectd now supports unicast
746 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
747 be set in the configfile.
749 2006-01-24, Version 3.6.2
750 * Due to a bug in the configfile handling collectd wouldn't start in
751 client mode. This released fixes this.
753 2006-01-20, Version 3.6.1
754 * Due to a bug in `configure.in' all modules and the binary were
755 linked against `libmysqlclient'. This issue is solved by this
758 2006-01-17, Version 3.6.0
759 * A config file has been added. This allows for loading only specific
761 * A `df' plugin has been added.
762 * A `mysql' plugin has been added.
763 * The `ping' plugin doesn't entirely give up hope when a socket error
764 occurred, but will back of and increase the intervals between tries.
766 2006-01-21, Version 3.5.2
767 * Fixed yet another bug in the signal handling.. Stupid typo..
768 * Improved the ping plugin to not give up on socket errors (backport
771 2005-12-18, Version 3.5.1
772 * The PID-file is now deleted correctly when shutting down the daemon.
773 * SIGINT and SIGTERM are now handled correctly.
775 2005-12-16, Version 3.5.0 (Revision 326)
776 * A bug in the `load' module under Solaris has been fixed.
777 * The `users' module has been contributed by Sebastian Harl. It counts
778 currently logged in users.
779 * The CPU module now works under FreeBSD without the use of
780 `libstatgrab', however SMP support is missing.
781 * The default directories for the RRD files and the PID file now
782 depend on the compile time setting of `localstatedir'.
784 2005-11-15, Version 3.4.0 (Revision 236)
785 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
786 from gentoo's bugzilla for writing the patch.
787 * The build dependency for librrd has been removed. Binaries built
788 without librrd are client-only and will multicast their value as
789 with the `-c' argument.
790 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
791 * The newly introduced `-f' switch prevents daemon initialization
792 (forking, closing standard filehandles, etc.) Thanks to Alvaro
793 Barcellos for this patch.
795 2005-11-04, Version 3.3.0 (Revision 216)
796 * New modules have been added:
797 - `serial', for monitoring traffic on the serial interfaces
798 - `nfs', for graphing NFS procedure calls
799 - `tape', traffic from/to tape devices
800 * The memory.rrd now accepts more than 4Gig of memory.
802 2005-10-26, Version 3.2.0 (Revision 200)
803 * Support for graphing the processes has been added (thanks to Lyonel
805 * If reading from hddtemp fails collectd will increase the time
806 between polls up to one day.
807 * The init.d files have been improved.
808 * Problems with the spec file have been fixed.
810 2005-10-16, Version 3.1.0 (Revision 194)
811 * Added the `setsid' syscall to the startup code.
812 * Support for hddtemp has been added (thanks to Vincent Stehlé)
814 2005-09-30, Version 3.0.0 (Revision 184)
815 * The ability to send/receive data to/from the network (think
816 multicast) has been added.
817 * Modules have been split up into shared libraries can be loaded at
818 runtime. The biggest advantage is that the core program doesn't need
819 to be linked against an external library.
820 * A patch by George Kargiotakis has been applied: It fixes the sensors
821 behaviour then more than one sensor is being queried.
823 2005-09-16, Version 2.1.0 (Revision 172)
824 * A module for swap statistics has been added.
826 2005-09-09, Version 2.0.0 (Revision 135)
827 * Filenames can no longer be configured at program startup. The only
828 options as of this version are the directory and ping hosts.
829 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
830 Soft-IRQ statistics are added to `System'.
831 * Diskstats now collect read and write bytes, not sectors.
832 * Ping statistics can now be collected for more than one host. There
833 is no default any more: If no host is given no host will be pinged.
834 * A self-written patch for libping has been applied so it builds
837 2005-09-01, Version 1.8.1 (Revision 123)
838 * Much improved configure-script: libraries and features may now be
840 * More detailed warnings/error messages when RRD update fails.
842 2005-08-29, Version 1.8.0:
843 * Support for collecting disk statistics under Solaris.
845 2005-08-25, Version 1.7.0:
846 * Support for libstatgrab[1] for load, memory usage and network
847 traffic. CPU- and disk-usage are not (yet) supported, since
848 libstatgrab returns insufficient information. I will contact the
850 * Improved the CPU-initialization code for Solaris. Apparently CPUs
851 aren't necessarily counted linear which is now handled correctly.
852 [1]: http://www.i-scream.org/libstatgrab/
854 2005-08-21, Version 1.6.0:
855 * Basic support for Solaris: System load and cpu-usage can be
856 collected under Solaris, too. Other stats will follow later.
857 * Many fixes in the autoconf-script
858 * Collection/Museum scripts have been added under contrib/museum
859 * collectd may now be started in unprivileged mode, though ping
860 statistics will not work.
862 2005-07-17, Version 1.5.1:
863 * Diskstats-RRDs now use major/minor for naming. Some systems have
864 weird strings as disk-names..
866 2005-07-17, Version 1.5:
867 * A new module, diskstats, has been added. It collects information
868 about the disks and partitions.
870 2005-07-11, Version 1.4.2:
871 * The meminfo module has been changed to work with more platforms
872 and/or kernel versions.
874 2005-07-10, Version 1.4.1: Correct traffic stats
875 * The traffic rrd-file is now created with DS-type `COUNTER' which I
876 forgot to correct when I changed that module.
878 2005-07-09, Version 1.4: More traffic stats
879 * Traffic is now collected for all interfaces that can be found
880 * Temperature-statistics are read from lm-sensors if available
882 2005-07-08, Version 1.3: CPU stats
883 * Collecting CPU statistics now
885 2004-07-12, Version 1.2: Using syslog
886 * collectd is now using the syslog facility to report errors, warnings
888 * The default directory is now /var/db/collectd
890 2004-07-10, Version 1.1: Minor changes
891 * Nothing really useful to say ;)
893 2004-07-09, Version 1.0: Initial Version
894 * The following modules are provided:
