29 using Linux ACPI thermal zone data.
31 2008-07-15, Version 4.4.2
32 * build system: Use pkg-config to detect the upsclient library.
33 * collectd: Try even harder to determine the endianess of the
34 architecture collectd is being built on.
35 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
37 * dns plugin: Fix compilation errors with BIND versions 19991001
39 * network plugin: Bugfix in the init routine: The init function

61 * collectd: Internal code cleanups.
62 * collectd: Added support for a `Flush' command in the unixsock and
63 exec plugins. This command can be used to force a plugin (or all) to
64 flush its values to disk.
65 * collectd: Thresholds can now be configured to apply to one data
66 source only, making it possible to configure different thresholds
68 * apache, nginx plugins: Added the possibility to disable host and/or
70 * ascent plugin: The new ascent plugin reads and parses the statistics
71 page of an Ascent server.
72 * cpu plugin: Support for the statgrab library has been added.
73 * disk plugin: The possibility to ignore certain disks or collect only
74 specific disks has been added.

76 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
77 sensor values via IPMI, the intelligent platform management
79 * iptables plugin: The iptc library that is used by the iptables
80 plugin has been added to the distribution, because it is not
81 provided by all distributions and removed from at least one.
82 * powerdns plugin: The new powerdns plugin reads statistics from an
83 authoritative or a recursing PowerDNS name server.
84 * rrdtool plugin: The size of the files generated with the default
85 configuration has been decreased.
86 * tail plugin: The new tail plugin can be used to gather statistics by
87 continuously reading from log files.

96 * build system: Improved detection of several libraries, especially if
97 they are in non-standard paths.
98 * build system: Portability fixes: Automatically define "_REENTRANT"
99 if the libc expects it.
100 * collectd: Error and warning messages have been improved.
101 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
103 * apache plugin: Allocate new memory when reading a webpage instead of

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

149 * exec plugin: Handling of notifications has been added and the
150 ability to pass arguments to the executed programs has been added.
151 * hddtemp plugin: The new `TranslateDevicename' option lets you
152 disable the translation from device names to major-minor-numbers.
153 * logfile plugin: Handling of notifications has been added.
154 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
155 domain name lookups in this plugin.
156 * perl plugin: Many internal changes added support for handling multiple
157 threads making the plugin reasonably usable inside collectd. The API has
158 been extended to support notifications and export global variables to
159 Perl plugins; callbacks now have to be identified by name rather than a
160 pointer to a subroutine. The plugin is no longer experimental.
161 * uuid plugin: The new UUID plugin sets the hostname to an unique
162 identifier for this host. This is meant for setups where each client
163 may migrate to another physical host, possibly going through one or
164 more name changes in the process. Thanks to Richard Jones from
165 Red Hat's Emerging Technology group for this plugin.
166 * libvirt: The new libvirt plugin uses the `libvirt' library to query
167 CPU, disk and network statistics about guest systems on the same
168 physical server. Thanks to Richard Jones from Red Hat's Emerging
169 Technology group for this plugin.
171 2008-04-22, Version 4.2.7
172 * build system: Improved detection of several libraries, especially if

175 if the libc expects it.
176 * collectd: Error and warning messages have been improved.
177 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
179 * apache plugin: Allocate new memory when reading a webpage instead of
180 using a buffer of static size.
181 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
183 * hddtemp plugin: Error and warning messages have been improved.
184 * sensors plugin: Fix sensor collection for some chip types.
186 2008-03-29, Version 4.2.6

188 * sensors plugin: Fix temperature collection with libsensors4.
189 * unixsock plugin: Fix mixed input and output operation on streams.
190 * wireless plugin: Fix reading noise value.
192 2008-03-04, Version 4.2.5
193 * apache plugin: Improved initialization and error messages.
194 * exec plugin: Set supplementary group IDs.
196 + Create separate threads for reading from the socket and parsing
197 and dispatching incoming packets. Versions prior to this may have
198 problems in high-load situations, where the socket receive buffers
199 overflows, resulting in gaps in the data.
200 + Use `memcpy' when constructing/parsing a package to avoid
201 alignment problems on weird architectures, such as Sparc.
202 + Translate doubles to/from the x86 byte representation to ensure
203 cross-platform compatibility.
204 * ping plugin: Correct the handling of the `TTL' setting.
205 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
206 * swap plugin: Reapply a patch for Solaris.
207 * tcpconns plugin: Portability improvements.
209 2008-01-21, Version 4.2.4
210 * unixsock plugin: A bug in the unixsock plugin caused it not to set
211 the permission on the socket as documented in the manpage. Thanks to
212 Evgeny Chukreev for fixing this issue.
213 * collectd: The documentation has been improved.
215 2007-12-28, Version 4.2.3
216 * sensors plugin: Updated the plugin to build and work with version 3
217 of the libsensors library.
219 2007-12-15, Version 4.2.2
220 * nginx plugin: Incorrect comparison of strings lead to a segfault
221 when using the plugin. Thanks to Saulius Grigaliunas for fixing
223 * logfile plugin: The config option `Timestamp' was handled
224 incorrectly and basically always active. Thanks to Luke Heberling
227 2007-11-08, Version 4.2.1
228 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
230 * snmp plugin: Fix a memory leak.
232 2007-10-27, Version 4.2.0
233 * collectd: The new config option `Include' lets you include other
234 configfiles and thus split up your config into smaller parts. This
235 may be especially interesting for the snmp plugin to keep the data
236 definitions separate from the host definitions.
237 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
238 (number of connections, octets and packets for each service and
239 destination). Thanks to Sebastian Harl for this plugin.
240 * memcached plugin: The new `memcached' plugin connects to a memcached
241 daemon process and collects statistics of this distributed caching
242 system. Thanks to Antony Dovgal for contributing this plugin.
243 * nginx plugin: The new `nginx' plugin reads the status page of an
244 nginx daemon and saves the handled connections and requests.
245 * perl plugin: Many changes, including the added `EnableDebugger'
246 config option which lets you debug your Perl plugins more easily.
247 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
248 be more thread-safe otherwise by locking calls to the library.
249 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
250 correct the values returned by SNMP-agents. If a <data> block is
251 defined as `table' the instance is now optional. The sequence number
252 is used as the type-instance in this case. The new `InstancePrefix'
253 option allows to add arbitrary prefixes to the type-instance.
254 * tcpconns plugin: The new `tcpconns' plugin collects the number of
255 certain TCP connections and what state they're in. This can be used
256 to see how many connections your FTP server has to handle or how
257 many outgoing connections your mailserver has open.
259 2008-01-11, Version 4.1.6
260 * unixsock plugin: A bug in the unixsock plugin caused it not to set
261 the permission on the socket as documented in the manpage. Thanks to

275 `--with-libnetsnmp' has been fixed.
276 * collectd: Implement `strerror_r' if the libc doesn't provide it.
277 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
278 a deadlock or delay when shutting down the daemon.
279 * snmp plugin: Fix a memory leak.
281 2007-10-24, Version 4.1.3
282 * collectd: A build issue under Solaris has been resolved by renaming
284 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
285 be more thread-safe otherwise by locking calls to the library.
287 2007-09-28, Version 4.1.2
288 * apcups plugin: Fix reporting of the `load percent' data.
289 * wireless plugin: Correct the handling of cards returning signal and
290 noise quality as percentage.

299 * Build system: The detection of `libnetlink' has been improved.
300 * collectd: The documentation has been fixed in numerous places.
301 * exec plugin: Setting the group under which to run a program has been
303 * collectd: The `sstrerror' function was improved to work correctly
304 with the broken GNU version of `strerror_r'.
305 * collectd: Write an error message to STDERR when loading of a plugin
307 * apcups plugin: Fix the `types' used to submit the values: They still
308 has an `apcups_' prefix which doesn't work anymore.
309 * rrdtool plugin: Create new RRD-files with the `begin' time set to
310 whatever the client thinks is `now'..
312 2007-09-01, Version 4.1.0
313 * Build system: The build system has been changed to automatically
314 disable all plugins, which are missing dependencies. The dependency
315 checking has been removed from the plugins themselves to remove
317 * Flexible interval: The interval of collected data is now sent along
318 with the data itself over the network, so that the interval-settings
319 of server and clients no longer needs to match.
320 * netlink plugin: The new `netlink' plugin connects to the Linux
321 kernel using a netlink socket and uses it to query information about
322 interfaces, qdiscs and classes.
323 * rrdtool plugin: The cache is now dumped to disk in an extra thread
324 to not block data collection.
325 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
326 network devices, such as switches, routers, thermometers, rack
327 monitoring servers, etc. The collectd-snmp(5) manpage documents this
329 * unixsock plugin: Added the `LISTVAL' command.
330 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
331 of music played with xmms.
333 2007-09-28, Version 4.0.9
334 * apcups plugin: Fix reporting of the `load percent' data.
335 * wireless plugin: Correct the handling of cards returning signal and
336 noise quality as percentage.
337 * perl plugin: Fix a possible buffer overflow in get_module_name().
339 2007-09-12, Version 4.0.8
340 * collectd: The `sstrerror' function was improved to work correctly
341 with the broken GNU version of `strerror_r'.
342 * collectd: Write an error message to STDERR when loading of a plugin
344 * apcups plugin: Fix the `types' used to submit the values: They still
345 has an `apcups_' prefix which doesn't work anymore.
346 * rrdtool plugin: Create new RRD-files with the `begin' time set to
347 whatever the client thinks is `now'..
349 2007-08-26, Version 4.0.7
350 * documentation: Some typos have been fixed and some information has
352 * build system: Many fixes for detecting libraries in unusual places,
353 such as on RedHat systems. The affected libraries are `libcurl',
354 `libmysql', and `libupsclient'.
355 * network plugin: Allow the `Port' option to be specified as a number
356 (i. e. without quotes).
357 * nut plugin: A fix allows linking the nut plugin against
358 libupsclient, version >= 2.2.0.
359 * processes plugin: Fix a potential segmentation fault.
361 2007-07-30, Version 4.0.6
362 * sensors plugin: Fix the ignorelist functionality: Only the `type
363 instance' was used to match against the list, but the documentation
364 told otherwise. This release fixes the code, so it complies with the
366 * syslog plugin: Call `openlog' right when the plugin is loaded, so
367 configuration messages will end up in the logging facility.
368 * conrtib/fedora: The contributed specfile for Fedora has been
371 2007-07-05, Version 4.0.5
372 * Portability: More fixes for OpenBSD have been included.
374 2007-06-24, Version 4.0.4

391 they're given in numerically form.
393 2007-06-07, Version 4.0.1
394 * iptables plugin: A bug in the configuration routine has been fixed.
395 Setting a comment in the configfile will no longer cause a
398 2007-06-03, Version 4.0.0
399 * collectd: The plugin-infrastructure has been changed to allow for
400 more types of plugins, namely `write' and `log' plugins.
401 * collectd: The read-function has been changed to read many plugins in
402 parallel, using threads. Thus, plugins generally need to use
403 thread-safe functions from now on.
404 * collectd: The '-t' command line options allows to perform syntax tests
405 of the configuration file and exit immediately.
406 * csv plugin: The new `csv' plugin handles output to `comma separated
408 * rrdtool plugin: The new `rrdtool' plugin handles output to
409 RRD-files. Data can be cached to combine multiple updates into one
410 write to increase IO-performance.
411 * network plugin: The new `network' plugin handles IO via the network.
412 It implements a different, much more extensible protocol which can
413 combine many values in one packet, decreasing the number of UDP-
414 packets being sent. It can read from and send to the network and
415 with the appropriate configuration even forward packets to other
417 * unixsock plugin: The new `unixsock' plugin provides an interface to
418 communicate with the daemon while it is running. Right now the
419 commands `GETVAL' and `PUTVAL' are implemented, but more are to
421 * perl plugin: The new `perl' plugin allows you to write extensions
422 for collectd in the scripting-language Perl.
423 * logfile plugin: The new `logfile' plugin writes logmessages to files
425 * syslog plugin: The new `syslog' plugin sends logmessages to the
426 system's syslog daemon.
427 * entropy plugin: The new `entropy' plugin collects the amount of
428 entropy currently being available to the system.
429 * exec plugin: The new `exec' plugin forks child processes and reads
430 back values provided by the forked processes.
431 * iptables plugin: The new `iptables' plugin reads counters from
432 iptables rules. Thanks to Sjoerd van der Berg for contributing this
434 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
435 to Peter Holik for contributing this plugin.
436 * nut plugin: The new `nut' plugin connects the upsd of the `network
437 ups tools' and reads information about the connected UPS.

439 connections) field was added by Florent Monbillard.
440 * collectd-nagios: The new `collectd-nagios' binary queries values
441 from collectd, parses them and exits according to Nagios-standards.
442 * manpages: The manpages have been improved a lot.
444 2007-09-28, Version 3.11.7
445 * wireless plugin: Correct the handling of cards returning signal and

455 were accounted as `zombies'.
457 2007-04-10, Version 3.11.4
458 * dns plugin: Change the order of includes to make the plugin compile
461 2007-03-30, Version 3.11.3
462 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
463 of the unused `COLLECT_KSTAT'.
465 2007-02-11, Version 3.11.2
466 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
467 NULL-pointer may have been passed to `printf' which causes a
468 segfault with some libcs.
470 2007-02-10, Version 3.11.1
471 * df plugin: Some wrong defines have been fixed so the plugin works
473 * dns plugin: The usage of a struct has been fixed to work with
475 * processes plugin: Some missing defines have been added so the plugin
476 compiles cleanly under FreeBSD and presumably other UNIXes.
478 2006-12-22, Version 3.11.0
479 * collectd: The new command line option `-P' makes it easier for
480 distributors to change the location of PID-files.
481 * collectd: The daemon shuts down faster now which makes it easier to
482 write init.d-scripts for it.
483 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
484 caused problems every now and then.
485 * df plugin: New config options allow to ignore certain mountpoints,
486 filesystem types or devices.
487 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
488 and interprets it. It collects traffic as well as qtype, opcode and
490 * email plugin: Sebastian Harl has contributed this plugin which
491 counts received mails in categories (e. g. ham, spam, virus), spam
492 score (as given by SpamAssassin) and check types.
493 * mbmon plugin: Flavio Stanchina has contributed this plugin which
494 uses `mbmon' to gather information from sensors on the motherboard.
495 * processes plugin: Collect detailed statistics for configured
496 processes, that's process and thread count, CPU usage, resident
497 segment size and pagefaults.
498 * multimeter plugin: Peter Holik contributed a new plugin which
500 * sensors plugin: Lubos Stanek has put much effort into improving this
501 plugin, including `extended naming', collection of voltage values
502 and the possibility to ignore certain values.
504 2006-12-21, Version 3.10.4
505 * Max Kellermann has identified a bug in the server routine: When
506 opening a socket fails the daemon will (re)try opening the socket in
507 an endless loop, ultimately leading to a `EMFILE' error.
509 2006-11-04, Version 3.10.3
510 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
511 ntpd's reply was sent in more than one packet, the buffer size was
512 calculated incorrectly, resulting in the reading of uninitialized or
515 2006-11-01, Version 3.10.2
516 * The sample config file has been improved.
517 * Errors in the manpages have been corrected.
518 * The ping-plugin now adds hosts during initialization, not during
519 startup. This speeds up startup when no network connectivity is
520 available. Also, the hosts are being added later when the network is
522 * Improved BSD-support for the df-plugin.
523 * Fixed syntax errors in the swap-plugin for Mac OS X.
524 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
526 * Don't disable the mysql-plugin if connecting to the database fails
527 during initialization. Instead, try again in increasing intervals.
529 2006-07-19, Version 3.10.1
530 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
531 the apcups cannot be reached, unconnected sockets will pile up and
532 eventually lead to `Too many open files' errors.
534 2006-07-09, Version 3.10.0
535 * The `disk' plugin has been ported to Darwin.
536 * The `battery' plugin should work on many Apple computers now.
537 * The `traffic' plugin can now ignore certain interfaces. Also,
538 statistics for sent/received packets and errors have been added.
539 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
540 to Anthony Gialluca for contributing this plugin and providing me
541 with a test environment :)
542 * A plugin for monitoring an NTP instance and the local clock drift
545 2006-06-25, Version 3.9.4
546 * The Solaris code in the `swap' plugin has been changed to reflect
547 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
549 * The debugging system has been fixed to work with the Sun libc.
550 * When built without librrd the variable `operating_mode' could be
551 uninitialized. Thanks to David Elliot for reporting the bug.
553 2006-06-01, Version 3.9.3
554 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
555 operating systems also profit from the changes, but I wasn't able to
557 * Changed the build system to find the netinet-includes under FreeBSD
558 and therefore successfully build the `liboping' library there.
560 2006-05-09, Version 3.9.2
561 * Applied a patch to the `liboping' library. Due to a bug in the
562 sequence checking the `ping' plugin stopped working after
563 approximately 7.6 days.
565 2006-05-09, Version 3.8.5
566 * Applied a patch to the `liboping' library. Due to a bug in the
567 sequence checking the `ping' plugin stopped working after
568 approximately 7.6 days.
570 2006-04-21, Version 3.9.1
571 * Build issues with Solaris and possible other architectures have been
573 * Problems when building the `apache'-plugin without `libcurl' have
575 * A bug in the `ping' plugin has been fixed. Sorry folks.
577 2006-04-02, Version 3.9.0
578 * A plugin to monitor the Apache webserver has been added.
579 <http://httpd.apache.org/>
580 * A plugin to collect statistics about virtual servers using VServer.
581 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
583 * A plugin for wireless LAN cards has been added. It monitors signal
584 strength, link quality and noise ratio..
585 * A plugin for Apple hardware sensors has been added.
586 * An option to compile collectd with different `step' and `heartbeat'
587 settings has been added. The size of RRAs is no longer static but
588 calculated based on the settings for `step' and `width'.
589 * The `ping' plugin can now be configured to use a certain TTL.
590 * A plugin to monitor the hardware sensors of Apple computers has been
592 * The plugins `cpu', `memory', `processes' and `traffic' have been
593 ported to Mach/Darwin (Mac OS X).
594 * The `log mode' has been contributed by Christophe Kalt. It writes
595 the data into text files rather than RRD files.
597 2006-04-09, Version 3.8.4
598 * Applied patch by Vincent Stehlé which improves the disk-name
599 resolution in the `hddtemp' plugin for Linux systems.
601 2006-04-02, Version 3.8.3
602 * Applied a patch by James Byers: The MySQL plugin was not working
603 with MySQL 5.0.2 or later.
605 2006-03-14, Version 3.8.2
606 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
607 the GNU libc, because it points to `/etc/fstab' rather than
610 2006-03-13, Version 3.8.1
611 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
612 * Fixes in the debian `postinst' and `init.d' scripts.
614 2006-03-09, Version 3.8.0
615 * The `ping' plugin no longer uses `libping' but a self written
616 library named `liboping'. With this library it's possible to ping
617 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
619 2006-02-18, Version 3.7.2
620 * A simple bug in the `battery' plugin has been fixed. It should now
621 work with ACPI based batteries as well. Thanks to Sebastian for
623 * Fixing a bug that prevented collectd to be built without librrd.
624 Thanks to Werner Heuser for reporting it.
626 2006-02-04, Version 3.7.1
627 * The new network code has been improved to build with older versions
629 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
630 to Tommie Gannert for this patch.
632 2006-01-30, Version 3.7.0
633 * The `battery' plugin has been added. It collects information about
635 * The MySQL plugin has been improved: It now writes two more RRD
636 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
637 * The `cpufreq' plugin now reads another file since the file it did
638 read so far causes much overhead in the kernel. Also, you need root
639 to read the old file, but not to read the new one.
640 * The `hddtemp' plugin can now be configured to connect to another
641 address and/or port than localhost.
642 * The `df' plugin now prefers `statvfs' over `statfs'.
643 * The network code has been rewritten. collectd now supports unicast
644 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
645 be set in the configfile.
647 2006-01-24, Version 3.6.2
648 * Due to a bug in the configfile handling collectd wouldn't start in
649 client mode. This released fixes this.
651 2006-01-20, Version 3.6.1
652 * Due to a bug in `configure.in' all modules and the binary were
653 linked against `libmysqlclient'. This issue is solved by this
656 2006-01-17, Version 3.6.0
657 * A config file has been added. This allows for loading only specific
659 * A `df' plugin has been added.
660 * A `mysql' plugin has been added.
661 * The `ping' plugin doesn't entirely give up hope when a socket error
662 occurred, but will back of and increase the intervals between tries.
664 2006-01-21, Version 3.5.2
665 * Fixed yet another bug in the signal handling.. Stupid typo..
666 * Improved the ping plugin to not give up on socket errors (backport
669 2005-12-18, Version 3.5.1
670 * The PID-file is now deleted correctly when shutting down the daemon.
671 * SIGINT and SIGTERM are now handled correctly.
673 2005-12-16, Version 3.5.0 (Revision 326)
674 * A bug in the `load' module under Solaris has been fixed.
675 * The `users' module has been contributed by Sebastian Harl. It counts
676 currently logged in users.
677 * The CPU module now works under FreeBSD without the use of
678 `libstatgrab', however SMP support is missing.
679 * The default directories for the RRD files and the PID file now
680 depend on the compile time setting of `localstatedir'.
682 2005-11-15, Version 3.4.0 (Revision 236)
683 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
684 from gentoo's bugzilla for writing the patch.
685 * The build dependency for librrd has been removed. Binaries built
686 without librrd are client-only and will multicast their value as
687 with the `-c' argument.
688 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
689 * The newly introduced `-f' switch prevents daemon initialization
690 (forking, closing standard filehandles, etc.) Thanks to Alvaro
691 Barcellos for this patch.
693 2005-11-04, Version 3.3.0 (Revision 216)
694 * New modules have been added:
695 - `serial', for monitoring traffic on the serial interfaces
696 - `nfs', for graphing NFS procedure calls
697 - `tape', traffic from/to tape devices
698 * The memory.rrd now accepts more than 4Gig of memory.
700 2005-10-26, Version 3.2.0 (Revision 200)
701 * Support for graphing the processes has been added (thanks to Lyonel
703 * If reading from hddtemp fails collectd will increase the time
704 between polls up to one day.
705 * The init.d files have been improved.
706 * Problems with the spec file have been fixed.
708 2005-10-16, Version 3.1.0 (Revision 194)
709 * Added the `setsid' syscall to the startup code.
710 * Support for hddtemp has been added (thanks to Vincent Stehlé)
712 2005-09-30, Version 3.0.0 (Revision 184)
713 * The ability to send/receive data to/from the network (think
714 multicast) has been added.
715 * Modules have been split up into shared libraries can be loaded at
716 runtime. The biggest advantage is that the core program doesn't need
717 to be linked against an external library.
718 * A patch by George Kargiotakis has been applied: It fixes the sensors
719 behaviour then more than one sensor is being queried.
721 2005-09-16, Version 2.1.0 (Revision 172)
722 * A module for swap statistics has been added.
724 2005-09-09, Version 2.0.0 (Revision 135)
725 * Filenames can no longer be configured at program startup. The only
726 options as of this version are the directory and ping hosts.
727 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
728 Soft-IRQ statistics are added to `System'.
729 * Diskstats now collect read and write bytes, not sectors.
730 * Ping statistics can now be collected for more than one host. There
731 is no default any more: If no host is given no host will be pinged.
732 * A self-written patch for libping has been applied so it builds
735 2005-09-01, Version 1.8.1 (Revision 123)
736 * Much improved configure-script: libraries and features may now be
738 * More detailed warnings/error messages when RRD update fails.
740 2005-08-29, Version 1.8.0:
741 * Support for collecting disk statistics under Solaris.
743 2005-08-25, Version 1.7.0:
744 * Support for libstatgrab[1] for load, memory usage and network
745 traffic. CPU- and disk-usage are not (yet) supported, since
746 libstatgrab returns insufficient information. I will contact the
748 * Improved the CPU-initialization code for Solaris. Apparently CPUs
749 aren't necessarily counted linear which is now handled correctly.
750 [1]: http://www.i-scream.org/libstatgrab/
752 2005-08-21, Version 1.6.0:
753 * Basic support for Solaris: System load and cpu-usage can be
754 collected under Solaris, too. Other stats will follow later.
755 * Many fixes in the autoconf-script
756 * Collection/Museum scripts have been added under contrib/museum
757 * collectd may now be started in unprivileged mode, though ping
758 statistics will not work.
760 2005-07-17, Version 1.5.1:
761 * Diskstats-RRDs now use major/minor for naming. Some systems have
762 weird strings as disk-names..
764 2005-07-17, Version 1.5:
765 * A new module, diskstats, has been added. It collects information
766 about the disks and partitions.
768 2005-07-11, Version 1.4.2:
769 * The meminfo module has been changed to work with more platforms
770 and/or kernel versions.
772 2005-07-10, Version 1.4.1: Correct traffic stats
773 * The traffic rrd-file is now created with DS-type `COUNTER' which I
774 forgot to correct when I changed that module.
776 2005-07-09, Version 1.4: More traffic stats
777 * Traffic is now collected for all interfaces that can be found
778 * Temperature-statistics are read from lm-sensors if available
780 2005-07-08, Version 1.3: CPU stats
781 * Collecting CPU statistics now
783 2004-07-12, Version 1.2: Using syslog
784 * collectd is now using the syslog facility to report errors, warnings
786 * The default directory is now /var/db/collectd
788 2004-07-10, Version 1.1: Minor changes
789 * Nothing really useful to say ;)
791 2004-07-09, Version 1.0: Initial Version
792 * The following modules are provided:
