1 2009-02-22, Version 4.5.3
2 * build system: The check for libupsclient even when `pkg-config' is
4 * collectd: Fix error handling in the global cache.
5 * Collectd::Unixsock: Error handling has been improved.
6 * ascent plugin: Fix a memory leak. Thanks to Bruno Prémont for his
8 * ipmi plugin: Fix an off-by-one error which could cause segmentation
9 faults. Thanks to Peter Holik for his patch.
10 * tcpconns plugin: An endianness problem has been fixed in the *BSD
11 code. Thanks to "thated" for reporting this.
13 2009-01-02, Version 4.5.2
14 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
15 file may be in both locations, especially when the database was
16 installed in a non-standard path. Thanks to Dusty Doris for
18 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
19 Solaris, in the configure script automatically.
20 * build system, tcpconns plugin: Check for `kvm_nlist' and
21 `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
22 library with similar functions to the BSD variant, but doesn't
23 provide these necessary functions.
24 * collectd.conf(5): Various fixes and clarifications.
25 * collectd: Remove a GNUism (unnamed unions), thus improving
27 * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
28 This solves portability problems, especially for Solaris.
29 * dns plugin: Fix a portability problem with NetBSD.
30 * filecount plugin: Fix an off-by-one error. This error may cause a
32 * network plugin: Fix the handling of `type' in the network protocol.
33 Due to a programming mistake, only 4 or 8 bytes would be copied to a
34 much larger buffer. This caused the `type' to be transferred much
35 more often than necessary. In some cases, e. g. the `cpu' and
36 `cpufreq' plugins being used at the same time, data may be corrupted
37 in those files. Thanks to Bruno Prémont for debugging and reporting
39 * processes plugin: Fix a possible segmentation fault when specifying
40 invalid configuration options.
41 * unixsock plugin: Make sure the initialization function is run only
42 once. This resolves a file descriptor leak under systems which run
43 the initialization more than once, such as Solaris.
45 2008-10-16, Version 4.5.1
46 * build system: Change `--enable-<plugin>' to abort with an error if
47 dependencies are not met. Thanks to Bruno Prémont for the patch.
48 Also, the poisoning of various string functions has been restricted
50 * collectd: Fix a memory leak in the global value cache. With every
51 *missing* value a couple of bytes would be leaked. Another memory
52 leak in the configuration handling code has been fixed. Thanks to
53 Niraj Tolia for reporting these issues.
54 * collectd: Fix an off-by-one error in the ignorelist functionality.
55 When using regular expressions, the last character would be missing,
56 possibly matching differently from what one would expect.
57 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
59 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
60 Linzberger for reporting the bug.
61 * iptables plugin: Fix an off-by-one error. If a string was just one
62 character too long, it was truncated instead of reporting an error.
63 * network plugin: Fix a memory leak in the configuration handling
64 code. Thanks to Niraj Tolia for reporting this issue.
65 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
66 * postgresql plugin: Don't reopen connection during reinitialization.
67 This fixes a bug under Solaris and potentially other platforms.
68 Missing calls to `PQclear' have been added, too. This fixes memory
69 leaks. Thanks to ``Admin'' for reporting these bugs.
70 * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
72 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
73 problems with some `libc's. Thanks to Matthias Lay for reporting the
76 2008-09-04, Version 4.5.0
77 * collectd: Added the ability to flush certain identifiers.
78 * collectd: The concept of `notification meta data' has been
80 * filecount plugin: The new filecount plugin counts the number of
81 files in a directory and its subdirectories.
82 * ipmi plugin: Sensor names have been changed to ensure unique names.
83 Notifications upon added and removed sensors can now be generated.
84 * notify_desktop plugin: This new plugin sends notifications to the
85 X desktop using the structure defined in the `Desktop Notification
87 * notify_email plugin: This new plugin sends out notifications via
88 email, using the `esmtp' library.
89 * onewire plugin: The new experimental(!) onewire plugin reads values,
90 such as temperatures, from sensors connected to the computer via the
92 * perl plugin: Improved synchronized access to internal data structures
93 and fixed a possible dead-lock.
94 * perl plugin: Added the ability to flush certain identifiers and marked
95 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
97 * perl plugin: Added the ability to configure Perl plugins.
98 * postgresql plugin: The new postgresql plugin collects statistics
99 about or from a PostgreSQL database.
100 * processes plugin: The `ProcessMatch' option has been added.
101 * rrdtool plugin: Implement throttling of the `update queue' to lessen
103 * tcpconns plugin: This plugin has been ported to OpenBSD.
104 * thermal plugin: The new thermal plugin collects system temperatures
105 using Linux ACPI thermal zone data.
107 2009-01-02, Version 4.4.5
108 * build system: Check for `mysql.h' and `mysql/mysql.h', since the
109 file may be in both locations, especially when the database was
110 installed in a non-standard path. Thanks to Dusty Doris for
112 * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
113 Solaris, in the configure script automatically.
114 * collectd.conf(5): Various fixes and clarifications.
115 * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
116 portability problems, especially for Solaris.
117 * dns plugin: Fix a portability problem with NetBSD.
118 * network plugin: Fix the handling of `type' in the network protocol.
119 Due to a programming mistake, only 4 or 8 bytes would be copied to a
120 much larger buffer. This caused the `type' to be transferred much
121 more often than necessary. In some cases, e. g. the `cpu' and
122 `cpufreq' plugins being used at the same time, data may be corrupted
123 in those files. Thanks to Bruno Prémont for debugging and reporting
125 * unixsock plugin: Make sure the initialization function is run only
126 once. This resolves a file descriptor leak under systems which run
127 the initialization more than once, such as Solaris.
129 2008-10-16, Version 4.4.4
130 * build system: Change `--enable-<plugin>' to abort with an error if
131 dependencies are not met. Thanks to Bruno Prémont for the patch.
132 Also, the poisoning of various string functions has been restricted
134 * collectd: Fix a memory leak in the global value cache. With every

146 code. Thanks to Niraj Tolia for reporting this issue.
147 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
148 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
149 problems with some `libc's. Thanks to Matthias Lay for reporting the
152 2008-09-01, Version 4.4.3

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

242 * build system: Improved detection of several libraries, especially if
243 they are in non-standard paths.
244 * build system: Portability fixes: Automatically define "_REENTRANT"
245 if the libc expects it.
246 * collectd: Error and warning messages have been improved.
247 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
249 * apache plugin: Allocate new memory when reading a webpage instead of
250 using a buffer of static size.
251 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
253 * hddtemp plugin: Error and warning messages have been improved.
254 * sensors plugin: Fix sensor collection for some chip types.
256 2008-03-29, Version 4.3.2
257 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
258 `Persist' threshold options.

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

336 * wireless plugin: Fix reading noise value.
338 2008-03-04, Version 4.2.5
339 * apache plugin: Improved initialization and error messages.
340 * exec plugin: Set supplementary group IDs.
342 + Create separate threads for reading from the socket and parsing
343 and dispatching incoming packets. Versions prior to this may have
344 problems in high-load situations, where the socket receive buffers
345 overflows, resulting in gaps in the data.
346 + Use `memcpy' when constructing/parsing a package to avoid
347 alignment problems on weird architectures, such as Sparc.
348 + Translate doubles to/from the x86 byte representation to ensure
349 cross-platform compatibility.
350 * ping plugin: Correct the handling of the `TTL' setting.
351 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
352 * swap plugin: Reapply a patch for Solaris.
353 * tcpconns plugin: Portability improvements.
355 2008-01-21, Version 4.2.4
356 * unixsock plugin: A bug in the unixsock plugin caused it not to set
357 the permission on the socket as documented in the manpage. Thanks to
358 Evgeny Chukreev for fixing this issue.
359 * collectd: The documentation has been improved.
361 2007-12-28, Version 4.2.3
362 * sensors plugin: Updated the plugin to build and work with version 3
363 of the libsensors library.
365 2007-12-15, Version 4.2.2
366 * nginx plugin: Incorrect comparison of strings lead to a segfault
367 when using the plugin. Thanks to Saulius Grigaliunas for fixing
369 * logfile plugin: The config option `Timestamp' was handled
370 incorrectly and basically always active. Thanks to Luke Heberling
373 2007-11-08, Version 4.2.1
374 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
376 * snmp plugin: Fix a memory leak.
378 2007-10-27, Version 4.2.0
379 * collectd: The new config option `Include' lets you include other
380 configfiles and thus split up your config into smaller parts. This
381 may be especially interesting for the snmp plugin to keep the data
382 definitions separate from the host definitions.
383 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
384 (number of connections, octets and packets for each service and
385 destination). Thanks to Sebastian Harl for this plugin.
386 * memcached plugin: The new `memcached' plugin connects to a memcached
387 daemon process and collects statistics of this distributed caching
388 system. Thanks to Antony Dovgal for contributing this plugin.
389 * nginx plugin: The new `nginx' plugin reads the status page of an
390 nginx daemon and saves the handled connections and requests.
391 * perl plugin: Many changes, including the added `EnableDebugger'
392 config option which lets you debug your Perl plugins more easily.
393 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
394 be more thread-safe otherwise by locking calls to the library.
395 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
396 correct the values returned by SNMP-agents. If a <data> block is
397 defined as `table' the instance is now optional. The sequence number
398 is used as the type-instance in this case. The new `InstancePrefix'
399 option allows to add arbitrary prefixes to the type-instance.
400 * tcpconns plugin: The new `tcpconns' plugin collects the number of
401 certain TCP connections and what state they're in. This can be used
402 to see how many connections your FTP server has to handle or how
403 many outgoing connections your mailserver has open.
405 2008-01-11, Version 4.1.6
406 * unixsock plugin: A bug in the unixsock plugin caused it not to set
407 the permission on the socket as documented in the manpage. Thanks to
408 Evgeny Chukreev for fixing this issue.

419 it's in a non-standard location.
420 * Build system: A bug when parsing the argument for
421 `--with-libnetsnmp' has been fixed.
422 * collectd: Implement `strerror_r' if the libc doesn't provide it.
423 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
424 a deadlock or delay when shutting down the daemon.
425 * snmp plugin: Fix a memory leak.
427 2007-10-24, Version 4.1.3
428 * collectd: A build issue under Solaris has been resolved by renaming
430 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
431 be more thread-safe otherwise by locking calls to the library.
433 2007-09-28, Version 4.1.2
434 * apcups plugin: Fix reporting of the `load percent' data.
435 * wireless plugin: Correct the handling of cards returning signal and
436 noise quality as percentage.
437 * perl plugin: Fix a possible buffer overflow in get_module_name().

442 support for the `timeticks' type.
444 2007-09-12, Version 4.1.1
445 * Build system: The detection of `libnetlink' has been improved.
446 * collectd: The documentation has been fixed in numerous places.
447 * exec plugin: Setting the group under which to run a program has been

450 with the broken GNU version of `strerror_r'.
451 * collectd: Write an error message to STDERR when loading of a plugin
453 * apcups plugin: Fix the `types' used to submit the values: They still
454 has an `apcups_' prefix which doesn't work anymore.
455 * rrdtool plugin: Create new RRD-files with the `begin' time set to
456 whatever the client thinks is `now'..
458 2007-09-01, Version 4.1.0
459 * Build system: The build system has been changed to automatically
460 disable all plugins, which are missing dependencies. The dependency
461 checking has been removed from the plugins themselves to remove
463 * Flexible interval: The interval of collected data is now sent along
464 with the data itself over the network, so that the interval-settings
465 of server and clients no longer needs to match.
466 * netlink plugin: The new `netlink' plugin connects to the Linux
467 kernel using a netlink socket and uses it to query information about
468 interfaces, qdiscs and classes.
469 * rrdtool plugin: The cache is now dumped to disk in an extra thread
470 to not block data collection.
471 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
472 network devices, such as switches, routers, thermometers, rack
473 monitoring servers, etc. The collectd-snmp(5) manpage documents this
475 * unixsock plugin: Added the `LISTVAL' command.
476 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
477 of music played with xmms.
479 2007-09-28, Version 4.0.9

487 with the broken GNU version of `strerror_r'.
488 * collectd: Write an error message to STDERR when loading of a plugin
490 * apcups plugin: Fix the `types' used to submit the values: They still
491 has an `apcups_' prefix which doesn't work anymore.
492 * rrdtool plugin: Create new RRD-files with the `begin' time set to
493 whatever the client thinks is `now'..
495 2007-08-26, Version 4.0.7
496 * documentation: Some typos have been fixed and some information has
498 * build system: Many fixes for detecting libraries in unusual places,
499 such as on RedHat systems. The affected libraries are `libcurl',
500 `libmysql', and `libupsclient'.
501 * network plugin: Allow the `Port' option to be specified as a number
502 (i. e. without quotes).
503 * nut plugin: A fix allows linking the nut plugin against
504 libupsclient, version >= 2.2.0.
505 * processes plugin: Fix a potential segmentation fault.
507 2007-07-30, Version 4.0.6
508 * sensors plugin: Fix the ignorelist functionality: Only the `type
509 instance' was used to match against the list, but the documentation
510 told otherwise. This release fixes the code, so it complies with the
512 * syslog plugin: Call `openlog' right when the plugin is loaded, so
513 configuration messages will end up in the logging facility.
514 * conrtib/fedora: The contributed specfile for Fedora has been
517 2007-07-05, Version 4.0.5
518 * Portability: More fixes for OpenBSD have been included.
520 2007-06-24, Version 4.0.4
521 * cpu plugin: Fixed the Solaris code.
522 * dns plugin: Fixed a build issue for OpenBSD.
523 * interface plugin: Fixed the Solaris code.
524 * load plugin: Fixed the alternative `/proc' Linux code.
525 * memory plugin: Fixed the Solaris code.
526 * oconfig: Don't require `-lfl' anymore.
528 2007-06-19, Version 4.0.3
529 * cpu plugin: Fix the Darwin / Mac OS X code.
530 * ping plugin: Use the return value of `getpid', not its address.
531 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
532 initialized correctly.
533 * configure: Added `--with-nan-emulation' to aid cross compilation.
535 2007-06-12, Version 4.0.2
536 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
537 they're given in numerically form.
539 2007-06-07, Version 4.0.1
540 * iptables plugin: A bug in the configuration routine has been fixed.
541 Setting a comment in the configfile will no longer cause a
544 2007-06-03, Version 4.0.0
545 * collectd: The plugin-infrastructure has been changed to allow for
546 more types of plugins, namely `write' and `log' plugins.
547 * collectd: The read-function has been changed to read many plugins in
548 parallel, using threads. Thus, plugins generally need to use
549 thread-safe functions from now on.
550 * collectd: The '-t' command line options allows to perform syntax tests
551 of the configuration file and exit immediately.
552 * csv plugin: The new `csv' plugin handles output to `comma separated
554 * rrdtool plugin: The new `rrdtool' plugin handles output to
555 RRD-files. Data can be cached to combine multiple updates into one
556 write to increase IO-performance.
557 * network plugin: The new `network' plugin handles IO via the network.
558 It implements a different, much more extensible protocol which can
559 combine many values in one packet, decreasing the number of UDP-
560 packets being sent. It can read from and send to the network and
561 with the appropriate configuration even forward packets to other
563 * unixsock plugin: The new `unixsock' plugin provides an interface to
564 communicate with the daemon while it is running. Right now the
565 commands `GETVAL' and `PUTVAL' are implemented, but more are to
567 * perl plugin: The new `perl' plugin allows you to write extensions
568 for collectd in the scripting-language Perl.
569 * logfile plugin: The new `logfile' plugin writes logmessages to files
571 * syslog plugin: The new `syslog' plugin sends logmessages to the
572 system's syslog daemon.
573 * entropy plugin: The new `entropy' plugin collects the amount of
574 entropy currently being available to the system.
575 * exec plugin: The new `exec' plugin forks child processes and reads
576 back values provided by the forked processes.
577 * iptables plugin: The new `iptables' plugin reads counters from
578 iptables rules. Thanks to Sjoerd van der Berg for contributing this
580 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
581 to Peter Holik for contributing this plugin.
582 * nut plugin: The new `nut' plugin connects the upsd of the `network
583 ups tools' and reads information about the connected UPS.
584 * apache plugin: Support for lighttpd's `BusyServers' (aka.
585 connections) field was added by Florent Monbillard.
586 * collectd-nagios: The new `collectd-nagios' binary queries values
587 from collectd, parses them and exits according to Nagios-standards.
588 * manpages: The manpages have been improved a lot.
590 2007-09-28, Version 3.11.7
591 * wireless plugin: Correct the handling of cards returning signal and
592 noise quality as percentage.
594 2007-08-31, Version 3.11.6
595 * processes plugin: Fix a potential segmentation fault.
597 2007-05-29, Version 3.11.5
598 * configure: Added `AC_SYS_LARGEFILE' for LFS.
599 * ntpd plugin: Fix a potential buffer overflow.
600 * processes plugin: Fix a bug when run under Linux 2.4. All processes
601 were accounted as `zombies'.
603 2007-04-10, Version 3.11.4
604 * dns plugin: Change the order of includes to make the plugin compile
607 2007-03-30, Version 3.11.3
608 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
609 of the unused `COLLECT_KSTAT'.
611 2007-02-11, Version 3.11.2
612 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
613 NULL-pointer may have been passed to `printf' which causes a
614 segfault with some libcs.
616 2007-02-10, Version 3.11.1
617 * df plugin: Some wrong defines have been fixed so the plugin works
619 * dns plugin: The usage of a struct has been fixed to work with
621 * processes plugin: Some missing defines have been added so the plugin
622 compiles cleanly under FreeBSD and presumably other UNIXes.
624 2006-12-22, Version 3.11.0
625 * collectd: The new command line option `-P' makes it easier for
626 distributors to change the location of PID-files.
627 * collectd: The daemon shuts down faster now which makes it easier to
628 write init.d-scripts for it.
629 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
630 caused problems every now and then.
631 * df plugin: New config options allow to ignore certain mountpoints,
632 filesystem types or devices.
633 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
634 and interprets it. It collects traffic as well as qtype, opcode and
636 * email plugin: Sebastian Harl has contributed this plugin which
637 counts received mails in categories (e. g. ham, spam, virus), spam
638 score (as given by SpamAssassin) and check types.
639 * mbmon plugin: Flavio Stanchina has contributed this plugin which
640 uses `mbmon' to gather information from sensors on the motherboard.
641 * processes plugin: Collect detailed statistics for configured
642 processes, that's process and thread count, CPU usage, resident
643 segment size and pagefaults.
644 * multimeter plugin: Peter Holik contributed a new plugin which
646 * sensors plugin: Lubos Stanek has put much effort into improving this
647 plugin, including `extended naming', collection of voltage values
648 and the possibility to ignore certain values.
650 2006-12-21, Version 3.10.4
651 * Max Kellermann has identified a bug in the server routine: When
652 opening a socket fails the daemon will (re)try opening the socket in
653 an endless loop, ultimately leading to a `EMFILE' error.
655 2006-11-04, Version 3.10.3
656 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
657 ntpd's reply was sent in more than one packet, the buffer size was
658 calculated incorrectly, resulting in the reading of uninitialized or
661 2006-11-01, Version 3.10.2
662 * The sample config file has been improved.
663 * Errors in the manpages have been corrected.
664 * The ping-plugin now adds hosts during initialization, not during
665 startup. This speeds up startup when no network connectivity is
666 available. Also, the hosts are being added later when the network is
668 * Improved BSD-support for the df-plugin.
669 * Fixed syntax errors in the swap-plugin for Mac OS X.
670 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
672 * Don't disable the mysql-plugin if connecting to the database fails
673 during initialization. Instead, try again in increasing intervals.
675 2006-07-19, Version 3.10.1
676 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
677 the apcups cannot be reached, unconnected sockets will pile up and
678 eventually lead to `Too many open files' errors.
680 2006-07-09, Version 3.10.0
681 * The `disk' plugin has been ported to Darwin.
682 * The `battery' plugin should work on many Apple computers now.
683 * The `traffic' plugin can now ignore certain interfaces. Also,
684 statistics for sent/received packets and errors have been added.
685 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
686 to Anthony Gialluca for contributing this plugin and providing me
687 with a test environment :)
688 * A plugin for monitoring an NTP instance and the local clock drift
691 2006-06-25, Version 3.9.4
692 * The Solaris code in the `swap' plugin has been changed to reflect
693 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
695 * The debugging system has been fixed to work with the Sun libc.
696 * When built without librrd the variable `operating_mode' could be
697 uninitialized. Thanks to David Elliot for reporting the bug.
699 2006-06-01, Version 3.9.3
700 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
701 operating systems also profit from the changes, but I wasn't able to
703 * Changed the build system to find the netinet-includes under FreeBSD
704 and therefore successfully build the `liboping' library there.
706 2006-05-09, Version 3.9.2
707 * Applied a patch to the `liboping' library. Due to a bug in the
708 sequence checking the `ping' plugin stopped working after
709 approximately 7.6 days.
711 2006-05-09, Version 3.8.5
712 * Applied a patch to the `liboping' library. Due to a bug in the
713 sequence checking the `ping' plugin stopped working after
714 approximately 7.6 days.
716 2006-04-21, Version 3.9.1
717 * Build issues with Solaris and possible other architectures have been
719 * Problems when building the `apache'-plugin without `libcurl' have
721 * A bug in the `ping' plugin has been fixed. Sorry folks.
723 2006-04-02, Version 3.9.0
724 * A plugin to monitor the Apache webserver has been added.
725 <http://httpd.apache.org/>
726 * A plugin to collect statistics about virtual servers using VServer.
727 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
729 * A plugin for wireless LAN cards has been added. It monitors signal
730 strength, link quality and noise ratio..
731 * A plugin for Apple hardware sensors has been added.
732 * An option to compile collectd with different `step' and `heartbeat'
733 settings has been added. The size of RRAs is no longer static but
734 calculated based on the settings for `step' and `width'.
735 * The `ping' plugin can now be configured to use a certain TTL.
736 * A plugin to monitor the hardware sensors of Apple computers has been
738 * The plugins `cpu', `memory', `processes' and `traffic' have been
739 ported to Mach/Darwin (Mac OS X).
740 * The `log mode' has been contributed by Christophe Kalt. It writes
741 the data into text files rather than RRD files.
743 2006-04-09, Version 3.8.4
744 * Applied patch by Vincent Stehlé which improves the disk-name
745 resolution in the `hddtemp' plugin for Linux systems.
747 2006-04-02, Version 3.8.3
748 * Applied a patch by James Byers: The MySQL plugin was not working
749 with MySQL 5.0.2 or later.
751 2006-03-14, Version 3.8.2
752 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
753 the GNU libc, because it points to `/etc/fstab' rather than
756 2006-03-13, Version 3.8.1
757 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
758 * Fixes in the debian `postinst' and `init.d' scripts.
760 2006-03-09, Version 3.8.0
761 * The `ping' plugin no longer uses `libping' but a self written
762 library named `liboping'. With this library it's possible to ping
763 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
765 2006-02-18, Version 3.7.2
766 * A simple bug in the `battery' plugin has been fixed. It should now
767 work with ACPI based batteries as well. Thanks to Sebastian for
769 * Fixing a bug that prevented collectd to be built without librrd.
770 Thanks to Werner Heuser for reporting it.
772 2006-02-04, Version 3.7.1
773 * The new network code has been improved to build with older versions
775 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
776 to Tommie Gannert for this patch.
778 2006-01-30, Version 3.7.0
779 * The `battery' plugin has been added. It collects information about
781 * The MySQL plugin has been improved: It now writes two more RRD
782 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
783 * The `cpufreq' plugin now reads another file since the file it did
784 read so far causes much overhead in the kernel. Also, you need root
785 to read the old file, but not to read the new one.
786 * The `hddtemp' plugin can now be configured to connect to another
787 address and/or port than localhost.
788 * The `df' plugin now prefers `statvfs' over `statfs'.
789 * The network code has been rewritten. collectd now supports unicast
790 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
791 be set in the configfile.
793 2006-01-24, Version 3.6.2
794 * Due to a bug in the configfile handling collectd wouldn't start in
795 client mode. This released fixes this.
797 2006-01-20, Version 3.6.1
798 * Due to a bug in `configure.in' all modules and the binary were
799 linked against `libmysqlclient'. This issue is solved by this
802 2006-01-17, Version 3.6.0
803 * A config file has been added. This allows for loading only specific
805 * A `df' plugin has been added.
806 * A `mysql' plugin has been added.
807 * The `ping' plugin doesn't entirely give up hope when a socket error
808 occurred, but will back of and increase the intervals between tries.
810 2006-01-21, Version 3.5.2
811 * Fixed yet another bug in the signal handling.. Stupid typo..
812 * Improved the ping plugin to not give up on socket errors (backport
815 2005-12-18, Version 3.5.1
816 * The PID-file is now deleted correctly when shutting down the daemon.
817 * SIGINT and SIGTERM are now handled correctly.
819 2005-12-16, Version 3.5.0 (Revision 326)
820 * A bug in the `load' module under Solaris has been fixed.
821 * The `users' module has been contributed by Sebastian Harl. It counts
822 currently logged in users.
823 * The CPU module now works under FreeBSD without the use of
824 `libstatgrab', however SMP support is missing.
825 * The default directories for the RRD files and the PID file now
826 depend on the compile time setting of `localstatedir'.
828 2005-11-15, Version 3.4.0 (Revision 236)
829 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
830 from gentoo's bugzilla for writing the patch.
831 * The build dependency for librrd has been removed. Binaries built
832 without librrd are client-only and will multicast their value as
833 with the `-c' argument.
834 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
835 * The newly introduced `-f' switch prevents daemon initialization
836 (forking, closing standard filehandles, etc.) Thanks to Alvaro
837 Barcellos for this patch.
839 2005-11-04, Version 3.3.0 (Revision 216)
840 * New modules have been added:
841 - `serial', for monitoring traffic on the serial interfaces
842 - `nfs', for graphing NFS procedure calls
843 - `tape', traffic from/to tape devices
844 * The memory.rrd now accepts more than 4Gig of memory.
846 2005-10-26, Version 3.2.0 (Revision 200)
847 * Support for graphing the processes has been added (thanks to Lyonel
849 * If reading from hddtemp fails collectd will increase the time
850 between polls up to one day.
851 * The init.d files have been improved.
852 * Problems with the spec file have been fixed.
854 2005-10-16, Version 3.1.0 (Revision 194)
855 * Added the `setsid' syscall to the startup code.
856 * Support for hddtemp has been added (thanks to Vincent Stehlé)
858 2005-09-30, Version 3.0.0 (Revision 184)
859 * The ability to send/receive data to/from the network (think
860 multicast) has been added.
861 * Modules have been split up into shared libraries can be loaded at
862 runtime. The biggest advantage is that the core program doesn't need
863 to be linked against an external library.
864 * A patch by George Kargiotakis has been applied: It fixes the sensors
865 behaviour then more than one sensor is being queried.
867 2005-09-16, Version 2.1.0 (Revision 172)
868 * A module for swap statistics has been added.
870 2005-09-09, Version 2.0.0 (Revision 135)
871 * Filenames can no longer be configured at program startup. The only
872 options as of this version are the directory and ping hosts.
873 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
874 Soft-IRQ statistics are added to `System'.
875 * Diskstats now collect read and write bytes, not sectors.
876 * Ping statistics can now be collected for more than one host. There
877 is no default any more: If no host is given no host will be pinged.
878 * A self-written patch for libping has been applied so it builds
881 2005-09-01, Version 1.8.1 (Revision 123)
882 * Much improved configure-script: libraries and features may now be
884 * More detailed warnings/error messages when RRD update fails.
886 2005-08-29, Version 1.8.0:
887 * Support for collecting disk statistics under Solaris.
889 2005-08-25, Version 1.7.0:
890 * Support for libstatgrab[1] for load, memory usage and network
891 traffic. CPU- and disk-usage are not (yet) supported, since
892 libstatgrab returns insufficient information. I will contact the
894 * Improved the CPU-initialization code for Solaris. Apparently CPUs
895 aren't necessarily counted linear which is now handled correctly.
896 [1]: http://www.i-scream.org/libstatgrab/
898 2005-08-21, Version 1.6.0:
899 * Basic support for Solaris: System load and cpu-usage can be
900 collected under Solaris, too. Other stats will follow later.
901 * Many fixes in the autoconf-script
902 * Collection/Museum scripts have been added under contrib/museum
903 * collectd may now be started in unprivileged mode, though ping
904 statistics will not work.
906 2005-07-17, Version 1.5.1:
907 * Diskstats-RRDs now use major/minor for naming. Some systems have
908 weird strings as disk-names..
910 2005-07-17, Version 1.5:
911 * A new module, diskstats, has been added. It collects information
912 about the disks and partitions.
914 2005-07-11, Version 1.4.2:
915 * The meminfo module has been changed to work with more platforms
916 and/or kernel versions.
918 2005-07-10, Version 1.4.1: Correct traffic stats
919 * The traffic rrd-file is now created with DS-type `COUNTER' which I
920 forgot to correct when I changed that module.
922 2005-07-09, Version 1.4: More traffic stats
923 * Traffic is now collected for all interfaces that can be found
924 * Temperature-statistics are read from lm-sensors if available
926 2005-07-08, Version 1.3: CPU stats
927 * Collecting CPU statistics now
929 2004-07-12, Version 1.2: Using syslog
930 * collectd is now using the syslog facility to report errors, warnings
932 * The default directory is now /var/db/collectd
934 2004-07-10, Version 1.1: Minor changes
935 * Nothing really useful to say ;)
937 2004-07-09, Version 1.0: Initial Version
938 * The following modules are provided:
projects / collectd.git / blob
