21 using Linux ACPI thermal zone data.
22 * TODO: onewire plugin?
24 2008-07-15, Version 4.4.2
25 * build system: Use pkg-config to detect the upsclient library.
26 * collectd: Try even harder to determine the endianess of the
27 architecture collectd is being built on.
28 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
30 * dns plugin: Fix compilation errors with BIND versions 19991001
32 * network plugin: Bugfix in the init routine: The init function

51 René Rebe and Siegmund Gorr for reporting this.
53 2008-05-06, Version 4.4.0
54 * collectd: Internal code cleanups.
55 * collectd: Added support for a `Flush' command in the unixsock and
56 exec plugins. This command can be used to force a plugin (or all) to
57 flush its values to disk.
58 * collectd: Thresholds can now be configured to apply to one data
59 source only, making it possible to configure different thresholds
61 * apache, nginx plugins: Added the possibility to disable host and/or
63 * ascent plugin: The new ascent plugin reads and parses the statistics
64 page of an Ascent server.
65 * cpu plugin: Support for the statgrab library has been added.
66 * disk plugin: The possibility to ignore certain disks or collect only
67 specific disks has been added.
68 * disk plugin: Support for the statgrab library has been added.
69 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
70 sensor values via IPMI, the intelligent platform management
72 * iptables plugin: The iptc library that is used by the iptables
73 plugin has been added to the distribution, because it is not
74 provided by all distributions and removed from at least one.
75 * powerdns plugin: The new powerdns plugin reads statistics from an
76 authoritative or a recursing PowerDNS name server.
77 * rrdtool plugin: The size of the files generated with the default
78 configuration has been decreased.
79 * tail plugin: The new tail plugin can be used to gather statistics by
80 continuously reading from log files.
81 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
82 TeamSpeak2 server and collects statistics about the number of users
83 and number of channels.
84 * users plugin: Support for the statgrab library has been added.
85 * vmem plugin: The new vmem plugin collects very detailed statistics
86 about the virtual memory subsystem of Linux.
88 2008-04-22, Version 4.3.3
89 * build system: Improved detection of several libraries, especially if
90 they are in non-standard paths.
91 * build system: Portability fixes: Automatically define "_REENTRANT"
92 if the libc expects it.
93 * collectd: Error and warning messages have been improved.
94 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
96 * apache plugin: Allocate new memory when reading a webpage instead of

112 2008-03-05, Version 4.3.1
113 * exec plugin: Set supplementary group IDs.
115 + Use `memcpy' when constructing/parsing a package to avoid
116 alignment problems on weird architectures, such as Sparc.
117 + Translate doubles to/from the x86 byte representation to ensure
118 cross-platform compatibility.
119 * ping plugin: Correct the handling of the `TTL' setting.
120 * swap plugin: Reapply a patch for Solaris.
121 * tcpconns plugin: Portability improvements.
123 2008-02-18, Version 4.3.0
124 * collectd: Notifications have been added to the daemon. Notifications
125 are status messages that may be associated with a data instance.
126 * collectd: Threshold checking has been added to the daemon. This
127 means that you can configure threshold values for each data
128 instance. If this threshold is exceeded a notification will be
130 * collectd: The new `FQDNLookup' option tells the daemon to use the
131 full qualified domain name as the hostname, not just the host part
132 es returned by `gethostname(2)'.
133 * collectd: Support for more than one `TypesDB' file has been added.
134 This is useful when one such file is included in a package but one
135 wants to add custom type definitions.
136 * collectd: The `Include' config option has been expanded to handle
137 entire directories and shell wildcards.
138 * collectdmon: The new `collectdmon' binary detects when collectd

142 * exec plugin: Handling of notifications has been added and the
143 ability to pass arguments to the executed programs has been added.
144 * hddtemp plugin: The new `TranslateDevicename' option lets you
145 disable the translation from device names to major-minor-numbers.
146 * logfile plugin: Handling of notifications has been added.
147 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
148 domain name lookups in this plugin.
149 * perl plugin: Many internal changes added support for handling multiple
150 threads making the plugin reasonably usable inside collectd. The API has
151 been extended to support notifications and export global variables to
152 Perl plugins; callbacks now have to be identified by name rather than a
153 pointer to a subroutine. The plugin is no longer experimental.
154 * uuid plugin: The new UUID plugin sets the hostname to an unique
155 identifier for this host. This is meant for setups where each client
156 may migrate to another physical host, possibly going through one or
157 more name changes in the process. Thanks to Richard Jones from
158 Red Hat's Emerging Technology group for this plugin.
159 * libvirt: The new libvirt plugin uses the `libvirt' library to query
160 CPU, disk and network statistics about guest systems on the same
161 physical server. Thanks to Richard Jones from Red Hat's Emerging
162 Technology group for this plugin.
164 2008-04-22, Version 4.2.7
165 * build system: Improved detection of several libraries, especially if
166 they are in non-standard paths.

168 if the libc expects it.
169 * collectd: Error and warning messages have been improved.
170 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
172 * apache plugin: Allocate new memory when reading a webpage instead of
173 using a buffer of static size.
174 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
176 * hddtemp plugin: Error and warning messages have been improved.
177 * sensors plugin: Fix sensor collection for some chip types.
179 2008-03-29, Version 4.2.6
180 * collectd: Improved error messages when parsing the configuration.
181 * sensors plugin: Fix temperature collection with libsensors4.
182 * unixsock plugin: Fix mixed input and output operation on streams.
183 * wireless plugin: Fix reading noise value.
185 2008-03-04, Version 4.2.5
186 * apache plugin: Improved initialization and error messages.
187 * exec plugin: Set supplementary group IDs.
189 + Create separate threads for reading from the socket and parsing
190 and dispatching incoming packets. Versions prior to this may have
191 problems in high-load situations, where the socket receive buffers
192 overflows, resulting in gaps in the data.
193 + Use `memcpy' when constructing/parsing a package to avoid
194 alignment problems on weird architectures, such as Sparc.
195 + Translate doubles to/from the x86 byte representation to ensure
196 cross-platform compatibility.
197 * ping plugin: Correct the handling of the `TTL' setting.
198 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
199 * swap plugin: Reapply a patch for Solaris.
200 * tcpconns plugin: Portability improvements.
202 2008-01-21, Version 4.2.4
203 * unixsock plugin: A bug in the unixsock plugin caused it not to set
204 the permission on the socket as documented in the manpage. Thanks to
205 Evgeny Chukreev for fixing this issue.
206 * collectd: The documentation has been improved.
208 2007-12-28, Version 4.2.3
209 * sensors plugin: Updated the plugin to build and work with version 3
210 of the libsensors library.
212 2007-12-15, Version 4.2.2
213 * nginx plugin: Incorrect comparison of strings lead to a segfault
214 when using the plugin. Thanks to Saulius Grigaliunas for fixing
216 * logfile plugin: The config option `Timestamp' was handled
217 incorrectly and basically always active. Thanks to Luke Heberling
220 2007-11-08, Version 4.2.1
221 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
223 * snmp plugin: Fix a memory leak.
225 2007-10-27, Version 4.2.0
226 * collectd: The new config option `Include' lets you include other
227 configfiles and thus split up your config into smaller parts. This
228 may be especially interesting for the snmp plugin to keep the data
229 definitions separate from the host definitions.
230 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
231 (number of connections, octets and packets for each service and
232 destination). Thanks to Sebastian Harl for this plugin.
233 * memcached plugin: The new `memcached' plugin connects to a memcached
234 daemon process and collects statistics of this distributed caching
235 system. Thanks to Antony Dovgal for contributing this plugin.
236 * nginx plugin: The new `nginx' plugin reads the status page of an
237 nginx daemon and saves the handled connections and requests.
238 * perl plugin: Many changes, including the added `EnableDebugger'
239 config option which lets you debug your Perl plugins more easily.
240 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
241 be more thread-safe otherwise by locking calls to the library.
242 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
243 correct the values returned by SNMP-agents. If a <data> block is
244 defined as `table' the instance is now optional. The sequence number
245 is used as the type-instance in this case. The new `InstancePrefix'
246 option allows to add arbitrary prefixes to the type-instance.
247 * tcpconns plugin: The new `tcpconns' plugin collects the number of
248 certain TCP connections and what state they're in. This can be used
249 to see how many connections your FTP server has to handle or how
250 many outgoing connections your mailserver has open.
252 2008-01-11, Version 4.1.6
253 * unixsock plugin: A bug in the unixsock plugin caused it not to set
254 the permission on the socket as documented in the manpage. Thanks to
255 Evgeny Chukreev for fixing this issue.
256 * collectd: The documentation has been improved.
258 2007-12-27, Version 4.1.5

266 it's in a non-standard location.
267 * Build system: A bug when parsing the argument for
268 `--with-libnetsnmp' has been fixed.
269 * collectd: Implement `strerror_r' if the libc doesn't provide it.
270 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
271 a deadlock or delay when shutting down the daemon.
272 * snmp plugin: Fix a memory leak.
274 2007-10-24, Version 4.1.3
275 * collectd: A build issue under Solaris has been resolved by renaming
277 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
278 be more thread-safe otherwise by locking calls to the library.
280 2007-09-28, Version 4.1.2
281 * apcups plugin: Fix reporting of the `load percent' data.
282 * wireless plugin: Correct the handling of cards returning signal and
283 noise quality as percentage.
284 * perl plugin: Fix a possible buffer overflow in get_module_name().

292 * Build system: The detection of `libnetlink' has been improved.
293 * collectd: The documentation has been fixed in numerous places.
294 * exec plugin: Setting the group under which to run a program has been
296 * collectd: The `sstrerror' function was improved to work correctly
297 with the broken GNU version of `strerror_r'.
298 * collectd: Write an error message to STDERR when loading of a plugin
300 * apcups plugin: Fix the `types' used to submit the values: They still
301 has an `apcups_' prefix which doesn't work anymore.
302 * rrdtool plugin: Create new RRD-files with the `begin' time set to
303 whatever the client thinks is `now'..
305 2007-09-01, Version 4.1.0
306 * Build system: The build system has been changed to automatically
307 disable all plugins, which are missing dependencies. The dependency
308 checking has been removed from the plugins themselves to remove
310 * Flexible interval: The interval of collected data is now sent along
311 with the data itself over the network, so that the interval-settings
312 of server and clients no longer needs to match.
313 * netlink plugin: The new `netlink' plugin connects to the Linux
314 kernel using a netlink socket and uses it to query information about
315 interfaces, qdiscs and classes.
316 * rrdtool plugin: The cache is now dumped to disk in an extra thread
317 to not block data collection.
318 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
319 network devices, such as switches, routers, thermometers, rack
320 monitoring servers, etc. The collectd-snmp(5) manpage documents this
322 * unixsock plugin: Added the `LISTVAL' command.
323 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
324 of music played with xmms.
326 2007-09-28, Version 4.0.9
327 * apcups plugin: Fix reporting of the `load percent' data.
328 * wireless plugin: Correct the handling of cards returning signal and
329 noise quality as percentage.
330 * perl plugin: Fix a possible buffer overflow in get_module_name().
332 2007-09-12, Version 4.0.8
333 * collectd: The `sstrerror' function was improved to work correctly
334 with the broken GNU version of `strerror_r'.
335 * collectd: Write an error message to STDERR when loading of a plugin
337 * apcups plugin: Fix the `types' used to submit the values: They still
338 has an `apcups_' prefix which doesn't work anymore.
339 * rrdtool plugin: Create new RRD-files with the `begin' time set to
340 whatever the client thinks is `now'..
342 2007-08-26, Version 4.0.7
343 * documentation: Some typos have been fixed and some information has
345 * build system: Many fixes for detecting libraries in unusual places,
346 such as on RedHat systems. The affected libraries are `libcurl',
347 `libmysql', and `libupsclient'.
348 * network plugin: Allow the `Port' option to be specified as a number
349 (i. e. without quotes).
350 * nut plugin: A fix allows linking the nut plugin against
351 libupsclient, version >= 2.2.0.
352 * processes plugin: Fix a potential segmentation fault.
354 2007-07-30, Version 4.0.6
355 * sensors plugin: Fix the ignorelist functionality: Only the `type
356 instance' was used to match against the list, but the documentation
357 told otherwise. This release fixes the code, so it complies with the
359 * syslog plugin: Call `openlog' right when the plugin is loaded, so
360 configuration messages will end up in the logging facility.
361 * conrtib/fedora: The contributed specfile for Fedora has been
364 2007-07-05, Version 4.0.5
365 * Portability: More fixes for OpenBSD have been included.
367 2007-06-24, Version 4.0.4
368 * cpu plugin: Fixed the Solaris code.

379 initialized correctly.
380 * configure: Added `--with-nan-emulation' to aid cross compilation.
382 2007-06-12, Version 4.0.2
383 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
384 they're given in numerically form.
386 2007-06-07, Version 4.0.1
387 * iptables plugin: A bug in the configuration routine has been fixed.
388 Setting a comment in the configfile will no longer cause a
391 2007-06-03, Version 4.0.0
392 * collectd: The plugin-infrastructure has been changed to allow for
393 more types of plugins, namely `write' and `log' plugins.
394 * collectd: The read-function has been changed to read many plugins in
395 parallel, using threads. Thus, plugins generally need to use
396 thread-safe functions from now on.
397 * collectd: The '-t' command line options allows to perform syntax tests
398 of the configuration file and exit immediately.
399 * csv plugin: The new `csv' plugin handles output to `comma separated
401 * rrdtool plugin: The new `rrdtool' plugin handles output to
402 RRD-files. Data can be cached to combine multiple updates into one
403 write to increase IO-performance.
404 * network plugin: The new `network' plugin handles IO via the network.
405 It implements a different, much more extensible protocol which can
406 combine many values in one packet, decreasing the number of UDP-
407 packets being sent. It can read from and send to the network and
408 with the appropriate configuration even forward packets to other
410 * unixsock plugin: The new `unixsock' plugin provides an interface to
411 communicate with the daemon while it is running. Right now the
412 commands `GETVAL' and `PUTVAL' are implemented, but more are to
414 * perl plugin: The new `perl' plugin allows you to write extensions
415 for collectd in the scripting-language Perl.
416 * logfile plugin: The new `logfile' plugin writes logmessages to files
418 * syslog plugin: The new `syslog' plugin sends logmessages to the
419 system's syslog daemon.
420 * entropy plugin: The new `entropy' plugin collects the amount of
421 entropy currently being available to the system.
422 * exec plugin: The new `exec' plugin forks child processes and reads
423 back values provided by the forked processes.
424 * iptables plugin: The new `iptables' plugin reads counters from
425 iptables rules. Thanks to Sjoerd van der Berg for contributing this
427 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
428 to Peter Holik for contributing this plugin.
429 * nut plugin: The new `nut' plugin connects the upsd of the `network
430 ups tools' and reads information about the connected UPS.
431 * apache plugin: Support for lighttpd's `BusyServers' (aka.
432 connections) field was added by Florent Monbillard.
433 * collectd-nagios: The new `collectd-nagios' binary queries values
434 from collectd, parses them and exits according to Nagios-standards.
435 * manpages: The manpages have been improved a lot.
437 2007-09-28, Version 3.11.7
438 * wireless plugin: Correct the handling of cards returning signal and

445 * configure: Added `AC_SYS_LARGEFILE' for LFS.
446 * ntpd plugin: Fix a potential buffer overflow.
447 * processes plugin: Fix a bug when run under Linux 2.4. All processes
448 were accounted as `zombies'.
450 2007-04-10, Version 3.11.4
451 * dns plugin: Change the order of includes to make the plugin compile
454 2007-03-30, Version 3.11.3
455 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
456 of the unused `COLLECT_KSTAT'.
458 2007-02-11, Version 3.11.2
459 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
460 NULL-pointer may have been passed to `printf' which causes a
461 segfault with some libcs.
463 2007-02-10, Version 3.11.1
464 * df plugin: Some wrong defines have been fixed so the plugin works
466 * dns plugin: The usage of a struct has been fixed to work with
468 * processes plugin: Some missing defines have been added so the plugin
469 compiles cleanly under FreeBSD and presumably other UNIXes.
471 2006-12-22, Version 3.11.0
472 * collectd: The new command line option `-P' makes it easier for
473 distributors to change the location of PID-files.
474 * collectd: The daemon shuts down faster now which makes it easier to
475 write init.d-scripts for it.
476 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
477 caused problems every now and then.
478 * df plugin: New config options allow to ignore certain mountpoints,
479 filesystem types or devices.
480 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
481 and interprets it. It collects traffic as well as qtype, opcode and
483 * email plugin: Sebastian Harl has contributed this plugin which
484 counts received mails in categories (e. g. ham, spam, virus), spam
485 score (as given by SpamAssassin) and check types.
486 * mbmon plugin: Flavio Stanchina has contributed this plugin which
487 uses `mbmon' to gather information from sensors on the motherboard.
488 * processes plugin: Collect detailed statistics for configured
489 processes, that's process and thread count, CPU usage, resident
490 segment size and pagefaults.
491 * multimeter plugin: Peter Holik contributed a new plugin which
493 * sensors plugin: Lubos Stanek has put much effort into improving this
494 plugin, including `extended naming', collection of voltage values
495 and the possibility to ignore certain values.
497 2006-12-21, Version 3.10.4
498 * Max Kellermann has identified a bug in the server routine: When
499 opening a socket fails the daemon will (re)try opening the socket in
500 an endless loop, ultimately leading to a `EMFILE' error.
502 2006-11-04, Version 3.10.3
503 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
504 ntpd's reply was sent in more than one packet, the buffer size was
505 calculated incorrectly, resulting in the reading of uninitialized or
508 2006-11-01, Version 3.10.2
509 * The sample config file has been improved.
510 * Errors in the manpages have been corrected.
511 * The ping-plugin now adds hosts during initialization, not during
512 startup. This speeds up startup when no network connectivity is
513 available. Also, the hosts are being added later when the network is
515 * Improved BSD-support for the df-plugin.
516 * Fixed syntax errors in the swap-plugin for Mac OS X.
517 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
519 * Don't disable the mysql-plugin if connecting to the database fails
520 during initialization. Instead, try again in increasing intervals.
522 2006-07-19, Version 3.10.1
523 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
524 the apcups cannot be reached, unconnected sockets will pile up and
525 eventually lead to `Too many open files' errors.
527 2006-07-09, Version 3.10.0
528 * The `disk' plugin has been ported to Darwin.
529 * The `battery' plugin should work on many Apple computers now.
530 * The `traffic' plugin can now ignore certain interfaces. Also,
531 statistics for sent/received packets and errors have been added.

533 to Anthony Gialluca for contributing this plugin and providing me
534 with a test environment :)
535 * A plugin for monitoring an NTP instance and the local clock drift
538 2006-06-25, Version 3.9.4
539 * The Solaris code in the `swap' plugin has been changed to reflect
540 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
542 * The debugging system has been fixed to work with the Sun libc.
543 * When built without librrd the variable `operating_mode' could be
544 uninitialized. Thanks to David Elliot for reporting the bug.
546 2006-06-01, Version 3.9.3
547 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
548 operating systems also profit from the changes, but I wasn't able to
550 * Changed the build system to find the netinet-includes under FreeBSD
551 and therefore successfully build the `liboping' library there.
553 2006-05-09, Version 3.9.2
554 * Applied a patch to the `liboping' library. Due to a bug in the
555 sequence checking the `ping' plugin stopped working after
556 approximately 7.6 days.
558 2006-05-09, Version 3.8.5
559 * Applied a patch to the `liboping' library. Due to a bug in the
560 sequence checking the `ping' plugin stopped working after
561 approximately 7.6 days.
563 2006-04-21, Version 3.9.1
564 * Build issues with Solaris and possible other architectures have been
566 * Problems when building the `apache'-plugin without `libcurl' have
568 * A bug in the `ping' plugin has been fixed. Sorry folks.
570 2006-04-02, Version 3.9.0
571 * A plugin to monitor the Apache webserver has been added.
572 <http://httpd.apache.org/>
573 * A plugin to collect statistics about virtual servers using VServer.
574 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing

577 strength, link quality and noise ratio..
578 * A plugin for Apple hardware sensors has been added.
579 * An option to compile collectd with different `step' and `heartbeat'
580 settings has been added. The size of RRAs is no longer static but
581 calculated based on the settings for `step' and `width'.
582 * The `ping' plugin can now be configured to use a certain TTL.
583 * A plugin to monitor the hardware sensors of Apple computers has been
585 * The plugins `cpu', `memory', `processes' and `traffic' have been
586 ported to Mach/Darwin (Mac OS X).
587 * The `log mode' has been contributed by Christophe Kalt. It writes
588 the data into text files rather than RRD files.
590 2006-04-09, Version 3.8.4
591 * Applied patch by Vincent Stehlé which improves the disk-name
592 resolution in the `hddtemp' plugin for Linux systems.
594 2006-04-02, Version 3.8.3
595 * Applied a patch by James Byers: The MySQL plugin was not working
596 with MySQL 5.0.2 or later.
598 2006-03-14, Version 3.8.2
599 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
600 the GNU libc, because it points to `/etc/fstab' rather than
603 2006-03-13, Version 3.8.1
604 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
605 * Fixes in the debian `postinst' and `init.d' scripts.
607 2006-03-09, Version 3.8.0
608 * The `ping' plugin no longer uses `libping' but a self written
609 library named `liboping'. With this library it's possible to ping
610 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
612 2006-02-18, Version 3.7.2
613 * A simple bug in the `battery' plugin has been fixed. It should now
614 work with ACPI based batteries as well. Thanks to Sebastian for
616 * Fixing a bug that prevented collectd to be built without librrd.
617 Thanks to Werner Heuser for reporting it.
619 2006-02-04, Version 3.7.1
620 * The new network code has been improved to build with older versions
622 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks

626 * The `battery' plugin has been added. It collects information about
628 * The MySQL plugin has been improved: It now writes two more RRD
629 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
630 * The `cpufreq' plugin now reads another file since the file it did
631 read so far causes much overhead in the kernel. Also, you need root
632 to read the old file, but not to read the new one.
633 * The `hddtemp' plugin can now be configured to connect to another
634 address and/or port than localhost.
635 * The `df' plugin now prefers `statvfs' over `statfs'.
636 * The network code has been rewritten. collectd now supports unicast
637 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
638 be set in the configfile.
640 2006-01-24, Version 3.6.2
641 * Due to a bug in the configfile handling collectd wouldn't start in
642 client mode. This released fixes this.
644 2006-01-20, Version 3.6.1
645 * Due to a bug in `configure.in' all modules and the binary were
646 linked against `libmysqlclient'. This issue is solved by this
649 2006-01-17, Version 3.6.0
650 * A config file has been added. This allows for loading only specific
652 * A `df' plugin has been added.
653 * A `mysql' plugin has been added.
654 * The `ping' plugin doesn't entirely give up hope when a socket error
655 occurred, but will back of and increase the intervals between tries.
657 2006-01-21, Version 3.5.2
658 * Fixed yet another bug in the signal handling.. Stupid typo..
659 * Improved the ping plugin to not give up on socket errors (backport
662 2005-12-18, Version 3.5.1

666 2005-12-16, Version 3.5.0 (Revision 326)
667 * A bug in the `load' module under Solaris has been fixed.
668 * The `users' module has been contributed by Sebastian Harl. It counts
669 currently logged in users.
670 * The CPU module now works under FreeBSD without the use of
671 `libstatgrab', however SMP support is missing.
672 * The default directories for the RRD files and the PID file now
673 depend on the compile time setting of `localstatedir'.
675 2005-11-15, Version 3.4.0 (Revision 236)
676 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
677 from gentoo's bugzilla for writing the patch.
678 * The build dependency for librrd has been removed. Binaries built
679 without librrd are client-only and will multicast their value as
680 with the `-c' argument.
681 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
682 * The newly introduced `-f' switch prevents daemon initialization
683 (forking, closing standard filehandles, etc.) Thanks to Alvaro
684 Barcellos for this patch.
686 2005-11-04, Version 3.3.0 (Revision 216)
687 * New modules have been added:
688 - `serial', for monitoring traffic on the serial interfaces
689 - `nfs', for graphing NFS procedure calls
690 - `tape', traffic from/to tape devices
691 * The memory.rrd now accepts more than 4Gig of memory.
693 2005-10-26, Version 3.2.0 (Revision 200)
694 * Support for graphing the processes has been added (thanks to Lyonel

697 between polls up to one day.
698 * The init.d files have been improved.
699 * Problems with the spec file have been fixed.
701 2005-10-16, Version 3.1.0 (Revision 194)
702 * Added the `setsid' syscall to the startup code.
703 * Support for hddtemp has been added (thanks to Vincent Stehlé)
705 2005-09-30, Version 3.0.0 (Revision 184)
706 * The ability to send/receive data to/from the network (think
707 multicast) has been added.
708 * Modules have been split up into shared libraries can be loaded at
709 runtime. The biggest advantage is that the core program doesn't need
710 to be linked against an external library.
711 * A patch by George Kargiotakis has been applied: It fixes the sensors
712 behaviour then more than one sensor is being queried.
714 2005-09-16, Version 2.1.0 (Revision 172)
715 * A module for swap statistics has been added.
717 2005-09-09, Version 2.0.0 (Revision 135)
718 * Filenames can no longer be configured at program startup. The only
719 options as of this version are the directory and ping hosts.
720 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
721 Soft-IRQ statistics are added to `System'.
722 * Diskstats now collect read and write bytes, not sectors.
723 * Ping statistics can now be collected for more than one host. There
724 is no default any more: If no host is given no host will be pinged.
725 * A self-written patch for libping has been applied so it builds
728 2005-09-01, Version 1.8.1 (Revision 123)
729 * Much improved configure-script: libraries and features may now be
731 * More detailed warnings/error messages when RRD update fails.
733 2005-08-29, Version 1.8.0:
734 * Support for collecting disk statistics under Solaris.
736 2005-08-25, Version 1.7.0:
737 * Support for libstatgrab[1] for load, memory usage and network
738 traffic. CPU- and disk-usage are not (yet) supported, since
739 libstatgrab returns insufficient information. I will contact the
741 * Improved the CPU-initialization code for Solaris. Apparently CPUs
742 aren't necessarily counted linear which is now handled correctly.
743 [1]: http://www.i-scream.org/libstatgrab/
745 2005-08-21, Version 1.6.0:
746 * Basic support for Solaris: System load and cpu-usage can be
747 collected under Solaris, too. Other stats will follow later.
748 * Many fixes in the autoconf-script
749 * Collection/Museum scripts have been added under contrib/museum
750 * collectd may now be started in unprivileged mode, though ping
751 statistics will not work.
753 2005-07-17, Version 1.5.1:
754 * Diskstats-RRDs now use major/minor for naming. Some systems have
755 weird strings as disk-names..
757 2005-07-17, Version 1.5:
758 * A new module, diskstats, has been added. It collects information
759 about the disks and partitions.
761 2005-07-11, Version 1.4.2:
762 * The meminfo module has been changed to work with more platforms
763 and/or kernel versions.
765 2005-07-10, Version 1.4.1: Correct traffic stats
766 * The traffic rrd-file is now created with DS-type `COUNTER' which I
767 forgot to correct when I changed that module.
769 2005-07-09, Version 1.4: More traffic stats
770 * Traffic is now collected for all interfaces that can be found
771 * Temperature-statistics are read from lm-sensors if available
773 2005-07-08, Version 1.3: CPU stats
774 * Collecting CPU statistics now
776 2004-07-12, Version 1.2: Using syslog
777 * collectd is now using the syslog facility to report errors, warnings
779 * The default directory is now /var/db/collectd
781 2004-07-10, Version 1.1: Minor changes
782 * Nothing really useful to say ;)
784 2004-07-09, Version 1.0: Initial Version
785 * The following modules are provided:
projects / collectd.git / blob
