1 2008-07-15, Version 4.4.2
2 * build system: Use pkg-config to detect the upsclient library.
3 * collectd: Try even harder to determine the endianess of the
4 architecture collectd is being built on.
5 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
7 * dns plugin: Fix compilation errors with BIND versions 19991001
9 * network plugin: Bugfix in the init routine: The init function
10 cleared a buffer regardless of its contents. This could lead to lost

21 * collectd-nagios: Fix the protocol used to communicate with the
23 * perl plugin: Fail noisily, but don't shutdown the daemon, if
24 initialization has errors. An issue with Perl 5.10 has been fixed.
25 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
26 René Rebe and Siegmund Gorr for reporting this.
28 2008-05-06, Version 4.4.0
29 * collectd: Internal code cleanups.
30 * collectd: Added support for a `Flush' command in the unixsock and
31 exec plugins. This command can be used to force a plugin (or all) to
32 flush its values to disk.
33 * collectd: Thresholds can now be configured to apply to one data
34 source only, making it possible to configure different thresholds
36 * apache, nginx plugins: Added the possibility to disable host and/or
38 * ascent plugin: The new ascent plugin reads and parses the statistics
39 page of an Ascent server.
40 * cpu plugin: Support for the statgrab library has been added.
41 * disk plugin: The possibility to ignore certain disks or collect only
42 specific disks has been added.
43 * disk plugin: Support for the statgrab library has been added.
44 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
45 sensor values via IPMI, the intelligent platform management
47 * iptables plugin: The iptc library that is used by the iptables
48 plugin has been added to the distribution, because it is not
49 provided by all distributions and removed from at least one.
50 * powerdns plugin: The new powerdns plugin reads statistics from an
51 authoritative or a recursing PowerDNS name server.
52 * rrdtool plugin: The size of the files generated with the default
53 configuration has been decreased.
54 * tail plugin: The new tail plugin can be used to gather statistics by
55 continuously reading from log files.
56 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
57 TeamSpeak2 server and collects statistics about the number of users
58 and number of channels.
59 * users plugin: Support for the statgrab library has been added.
60 * vmem plugin: The new vmem plugin collects very detailed statistics
61 about the virtual memory subsystem of Linux.
63 2008-04-22, Version 4.3.3
64 * build system: Improved detection of several libraries, especially if
65 they are in non-standard paths.
66 * build system: Portability fixes: Automatically define "_REENTRANT"
67 if the libc expects it.
68 * collectd: Error and warning messages have been improved.
69 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
71 * apache plugin: Allocate new memory when reading a webpage instead of
72 using a buffer of static size.
73 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
75 * hddtemp plugin: Error and warning messages have been improved.
76 * sensors plugin: Fix sensor collection for some chip types.
78 2008-03-29, Version 4.3.2
79 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
80 `Persist' threshold options.
81 * collectd: Fix handling of missing values in the global value cache.
82 * collectd: Improved error messages when parsing the configuration.
83 * sensors plugin: Fix temperature collection with libsensors4.
84 * unixsock plugin: Fix mixed input and output operation on streams.
85 * wireless plugin: Fix reading noise value.
87 2008-03-05, Version 4.3.1
88 * exec plugin: Set supplementary group IDs.
90 + Use `memcpy' when constructing/parsing a package to avoid
91 alignment problems on weird architectures, such as Sparc.
92 + Translate doubles to/from the x86 byte representation to ensure
93 cross-platform compatibility.
94 * ping plugin: Correct the handling of the `TTL' setting.
95 * swap plugin: Reapply a patch for Solaris.
96 * tcpconns plugin: Portability improvements.
98 2008-02-18, Version 4.3.0
99 * collectd: Notifications have been added to the daemon. Notifications
100 are status messages that may be associated with a data instance.
101 * collectd: Threshold checking has been added to the daemon. This
102 means that you can configure threshold values for each data
103 instance. If this threshold is exceeded a notification will be
105 * collectd: The new `FQDNLookup' option tells the daemon to use the
106 full qualified domain name as the hostname, not just the host part
107 es returned by `gethostname(2)'.
108 * collectd: Support for more than one `TypesDB' file has been added.
109 This is useful when one such file is included in a package but one
110 wants to add custom type definitions.
111 * collectd: The `Include' config option has been expanded to handle
112 entire directories and shell wildcards.
113 * collectdmon: The new `collectdmon' binary detects when collectd
114 terminates and automatically restarts it again.
115 * csv plugin: The CSV plugin is now able to store counter values as a
116 rate, using the `StoreRates' configuration option.
117 * exec plugin: Handling of notifications has been added and the
118 ability to pass arguments to the executed programs has been added.
119 * hddtemp plugin: The new `TranslateDevicename' option lets you
120 disable the translation from device names to major-minor-numbers.
121 * logfile plugin: Handling of notifications has been added.
122 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
123 domain name lookups in this plugin.
124 * perl plugin: Many internal changes added support for handling multiple
125 threads making the plugin reasonably usable inside collectd. The API has
126 been extended to support notifications and export global variables to
127 Perl plugins; callbacks now have to be identified by name rather than a
128 pointer to a subroutine. The plugin is no longer experimental.
129 * uuid plugin: The new UUID plugin sets the hostname to an unique
130 identifier for this host. This is meant for setups where each client
131 may migrate to another physical host, possibly going through one or
132 more name changes in the process. Thanks to Richard Jones from
133 Red Hat's Emerging Technology group for this plugin.
134 * libvirt: The new libvirt plugin uses the `libvirt' library to query
135 CPU, disk and network statistics about guest systems on the same
136 physical server. Thanks to Richard Jones from Red Hat's Emerging
137 Technology group for this plugin.
139 2008-04-22, Version 4.2.7
140 * build system: Improved detection of several libraries, especially if
141 they are in non-standard paths.

143 if the libc expects it.
144 * collectd: Error and warning messages have been improved.
145 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
147 * apache plugin: Allocate new memory when reading a webpage instead of
148 using a buffer of static size.
149 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
151 * hddtemp plugin: Error and warning messages have been improved.
152 * sensors plugin: Fix sensor collection for some chip types.
154 2008-03-29, Version 4.2.6

156 * sensors plugin: Fix temperature collection with libsensors4.
157 * unixsock plugin: Fix mixed input and output operation on streams.
158 * wireless plugin: Fix reading noise value.
160 2008-03-04, Version 4.2.5
161 * apache plugin: Improved initialization and error messages.
162 * exec plugin: Set supplementary group IDs.
164 + Create separate threads for reading from the socket and parsing
165 and dispatching incoming packets. Versions prior to this may have
166 problems in high-load situations, where the socket receive buffers
167 overflows, resulting in gaps in the data.
168 + Use `memcpy' when constructing/parsing a package to avoid
169 alignment problems on weird architectures, such as Sparc.
170 + Translate doubles to/from the x86 byte representation to ensure
171 cross-platform compatibility.
172 * ping plugin: Correct the handling of the `TTL' setting.
173 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
174 * swap plugin: Reapply a patch for Solaris.
175 * tcpconns plugin: Portability improvements.
177 2008-01-21, Version 4.2.4
178 * unixsock plugin: A bug in the unixsock plugin caused it not to set
179 the permission on the socket as documented in the manpage. Thanks to
180 Evgeny Chukreev for fixing this issue.
181 * collectd: The documentation has been improved.
183 2007-12-28, Version 4.2.3
184 * sensors plugin: Updated the plugin to build and work with version 3
185 of the libsensors library.
187 2007-12-15, Version 4.2.2
188 * nginx plugin: Incorrect comparison of strings lead to a segfault
189 when using the plugin. Thanks to Saulius Grigaliunas for fixing
191 * logfile plugin: The config option `Timestamp' was handled
192 incorrectly and basically always active. Thanks to Luke Heberling
195 2007-11-08, Version 4.2.1
196 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
198 * snmp plugin: Fix a memory leak.
200 2007-10-27, Version 4.2.0
201 * collectd: The new config option `Include' lets you include other
202 configfiles and thus split up your config into smaller parts. This
203 may be especially interesting for the snmp plugin to keep the data
204 definitions separate from the host definitions.
205 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
206 (number of connections, octets and packets for each service and
207 destination). Thanks to Sebastian Harl for this plugin.
208 * memcached plugin: The new `memcached' plugin connects to a memcached
209 daemon process and collects statistics of this distributed caching
210 system. Thanks to Antony Dovgal for contributing this plugin.
211 * nginx plugin: The new `nginx' plugin reads the status page of an
212 nginx daemon and saves the handled connections and requests.
213 * perl plugin: Many changes, including the added `EnableDebugger'
214 config option which lets you debug your Perl plugins more easily.
215 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
216 be more thread-safe otherwise by locking calls to the library.
217 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
218 correct the values returned by SNMP-agents. If a <data> block is
219 defined as `table' the instance is now optional. The sequence number
220 is used as the type-instance in this case. The new `InstancePrefix'
221 option allows to add arbitrary prefixes to the type-instance.
222 * tcpconns plugin: The new `tcpconns' plugin collects the number of
223 certain TCP connections and what state they're in. This can be used
224 to see how many connections your FTP server has to handle or how
225 many outgoing connections your mailserver has open.
227 2008-01-11, Version 4.1.6
228 * unixsock plugin: A bug in the unixsock plugin caused it not to set
229 the permission on the socket as documented in the manpage. Thanks to
230 Evgeny Chukreev for fixing this issue.
231 * collectd: The documentation has been improved.
233 2007-12-27, Version 4.1.5

241 it's in a non-standard location.
242 * Build system: A bug when parsing the argument for
243 `--with-libnetsnmp' has been fixed.
244 * collectd: Implement `strerror_r' if the libc doesn't provide it.
245 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
246 a deadlock or delay when shutting down the daemon.
247 * snmp plugin: Fix a memory leak.
249 2007-10-24, Version 4.1.3
250 * collectd: A build issue under Solaris has been resolved by renaming
252 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
253 be more thread-safe otherwise by locking calls to the library.
255 2007-09-28, Version 4.1.2
256 * apcups plugin: Fix reporting of the `load percent' data.
257 * wireless plugin: Correct the handling of cards returning signal and
258 noise quality as percentage.

267 * Build system: The detection of `libnetlink' has been improved.
268 * collectd: The documentation has been fixed in numerous places.
269 * exec plugin: Setting the group under which to run a program has been
271 * collectd: The `sstrerror' function was improved to work correctly
272 with the broken GNU version of `strerror_r'.
273 * collectd: Write an error message to STDERR when loading of a plugin
275 * apcups plugin: Fix the `types' used to submit the values: They still
276 has an `apcups_' prefix which doesn't work anymore.
277 * rrdtool plugin: Create new RRD-files with the `begin' time set to
278 whatever the client thinks is `now'..
280 2007-09-01, Version 4.1.0
281 * Build system: The build system has been changed to automatically
282 disable all plugins, which are missing dependencies. The dependency
283 checking has been removed from the plugins themselves to remove
285 * Flexible interval: The interval of collected data is now sent along
286 with the data itself over the network, so that the interval-settings
287 of server and clients no longer needs to match.
288 * netlink plugin: The new `netlink' plugin connects to the Linux
289 kernel using a netlink socket and uses it to query information about
290 interfaces, qdiscs and classes.
291 * rrdtool plugin: The cache is now dumped to disk in an extra thread
292 to not block data collection.
293 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
294 network devices, such as switches, routers, thermometers, rack
295 monitoring servers, etc. The collectd-snmp(5) manpage documents this
297 * unixsock plugin: Added the `LISTVAL' command.
298 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
299 of music played with xmms.
301 2007-09-28, Version 4.0.9
302 * apcups plugin: Fix reporting of the `load percent' data.
303 * wireless plugin: Correct the handling of cards returning signal and
304 noise quality as percentage.
305 * perl plugin: Fix a possible buffer overflow in get_module_name().
307 2007-09-12, Version 4.0.8
308 * collectd: The `sstrerror' function was improved to work correctly
309 with the broken GNU version of `strerror_r'.
310 * collectd: Write an error message to STDERR when loading of a plugin
312 * apcups plugin: Fix the `types' used to submit the values: They still
313 has an `apcups_' prefix which doesn't work anymore.
314 * rrdtool plugin: Create new RRD-files with the `begin' time set to
315 whatever the client thinks is `now'..
317 2007-08-26, Version 4.0.7
318 * documentation: Some typos have been fixed and some information has
320 * build system: Many fixes for detecting libraries in unusual places,
321 such as on RedHat systems. The affected libraries are `libcurl',
322 `libmysql', and `libupsclient'.
323 * network plugin: Allow the `Port' option to be specified as a number
324 (i. e. without quotes).
325 * nut plugin: A fix allows linking the nut plugin against
326 libupsclient, version >= 2.2.0.
327 * processes plugin: Fix a potential segmentation fault.
329 2007-07-30, Version 4.0.6
330 * sensors plugin: Fix the ignorelist functionality: Only the `type
331 instance' was used to match against the list, but the documentation
332 told otherwise. This release fixes the code, so it complies with the
334 * syslog plugin: Call `openlog' right when the plugin is loaded, so
335 configuration messages will end up in the logging facility.
336 * conrtib/fedora: The contributed specfile for Fedora has been
339 2007-07-05, Version 4.0.5
340 * Portability: More fixes for OpenBSD have been included.
342 2007-06-24, Version 4.0.4
343 * cpu plugin: Fixed the Solaris code.

359 they're given in numerically form.
361 2007-06-07, Version 4.0.1
362 * iptables plugin: A bug in the configuration routine has been fixed.
363 Setting a comment in the configfile will no longer cause a
366 2007-06-03, Version 4.0.0
367 * collectd: The plugin-infrastructure has been changed to allow for
368 more types of plugins, namely `write' and `log' plugins.
369 * collectd: The read-function has been changed to read many plugins in
370 parallel, using threads. Thus, plugins generally need to use
371 thread-safe functions from now on.
372 * collectd: The '-t' command line options allows to perform syntax tests
373 of the configuration file and exit immediately.
374 * csv plugin: The new `csv' plugin handles output to `comma separated
376 * rrdtool plugin: The new `rrdtool' plugin handles output to
377 RRD-files. Data can be cached to combine multiple updates into one
378 write to increase IO-performance.
379 * network plugin: The new `network' plugin handles IO via the network.
380 It implements a different, much more extensible protocol which can
381 combine many values in one packet, decreasing the number of UDP-
382 packets being sent. It can read from and send to the network and
383 with the appropriate configuration even forward packets to other
385 * unixsock plugin: The new `unixsock' plugin provides an interface to
386 communicate with the daemon while it is running. Right now the
387 commands `GETVAL' and `PUTVAL' are implemented, but more are to
389 * perl plugin: The new `perl' plugin allows you to write extensions
390 for collectd in the scripting-language Perl.
391 * logfile plugin: The new `logfile' plugin writes logmessages to files
393 * syslog plugin: The new `syslog' plugin sends logmessages to the
394 system's syslog daemon.
395 * entropy plugin: The new `entropy' plugin collects the amount of
396 entropy currently being available to the system.
397 * exec plugin: The new `exec' plugin forks child processes and reads
398 back values provided by the forked processes.
399 * iptables plugin: The new `iptables' plugin reads counters from
400 iptables rules. Thanks to Sjoerd van der Berg for contributing this
402 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
403 to Peter Holik for contributing this plugin.
404 * nut plugin: The new `nut' plugin connects the upsd of the `network
405 ups tools' and reads information about the connected UPS.
406 * apache plugin: Support for lighttpd's `BusyServers' (aka.
407 connections) field was added by Florent Monbillard.
408 * collectd-nagios: The new `collectd-nagios' binary queries values
409 from collectd, parses them and exits according to Nagios-standards.
410 * manpages: The manpages have been improved a lot.
412 2007-09-28, Version 3.11.7
413 * wireless plugin: Correct the handling of cards returning signal and

422 * processes plugin: Fix a bug when run under Linux 2.4. All processes
423 were accounted as `zombies'.
425 2007-04-10, Version 3.11.4
426 * dns plugin: Change the order of includes to make the plugin compile
429 2007-03-30, Version 3.11.3
430 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
431 of the unused `COLLECT_KSTAT'.
433 2007-02-11, Version 3.11.2
434 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
435 NULL-pointer may have been passed to `printf' which causes a
436 segfault with some libcs.
438 2007-02-10, Version 3.11.1
439 * df plugin: Some wrong defines have been fixed so the plugin works
441 * dns plugin: The usage of a struct has been fixed to work with
443 * processes plugin: Some missing defines have been added so the plugin
444 compiles cleanly under FreeBSD and presumably other UNIXes.
446 2006-12-22, Version 3.11.0
447 * collectd: The new command line option `-P' makes it easier for
448 distributors to change the location of PID-files.
449 * collectd: The daemon shuts down faster now which makes it easier to
450 write init.d-scripts for it.
451 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
452 caused problems every now and then.
453 * df plugin: New config options allow to ignore certain mountpoints,
454 filesystem types or devices.
455 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
456 and interprets it. It collects traffic as well as qtype, opcode and
458 * email plugin: Sebastian Harl has contributed this plugin which
459 counts received mails in categories (e. g. ham, spam, virus), spam
460 score (as given by SpamAssassin) and check types.
461 * mbmon plugin: Flavio Stanchina has contributed this plugin which
462 uses `mbmon' to gather information from sensors on the motherboard.
463 * processes plugin: Collect detailed statistics for configured
464 processes, that's process and thread count, CPU usage, resident
465 segment size and pagefaults.
466 * multimeter plugin: Peter Holik contributed a new plugin which
468 * sensors plugin: Lubos Stanek has put much effort into improving this
469 plugin, including `extended naming', collection of voltage values
470 and the possibility to ignore certain values.
472 2006-12-21, Version 3.10.4
473 * Max Kellermann has identified a bug in the server routine: When
474 opening a socket fails the daemon will (re)try opening the socket in
475 an endless loop, ultimately leading to a `EMFILE' error.
477 2006-11-04, Version 3.10.3
478 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
479 ntpd's reply was sent in more than one packet, the buffer size was
480 calculated incorrectly, resulting in the reading of uninitialized or
483 2006-11-01, Version 3.10.2
484 * The sample config file has been improved.
485 * Errors in the manpages have been corrected.
486 * The ping-plugin now adds hosts during initialization, not during
487 startup. This speeds up startup when no network connectivity is
488 available. Also, the hosts are being added later when the network is
490 * Improved BSD-support for the df-plugin.
491 * Fixed syntax errors in the swap-plugin for Mac OS X.
492 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
494 * Don't disable the mysql-plugin if connecting to the database fails
495 during initialization. Instead, try again in increasing intervals.
497 2006-07-19, Version 3.10.1
498 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
499 the apcups cannot be reached, unconnected sockets will pile up and
500 eventually lead to `Too many open files' errors.
502 2006-07-09, Version 3.10.0
503 * The `disk' plugin has been ported to Darwin.
504 * The `battery' plugin should work on many Apple computers now.
505 * The `traffic' plugin can now ignore certain interfaces. Also,
506 statistics for sent/received packets and errors have been added.
507 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
508 to Anthony Gialluca for contributing this plugin and providing me
509 with a test environment :)
510 * A plugin for monitoring an NTP instance and the local clock drift
513 2006-06-25, Version 3.9.4
514 * The Solaris code in the `swap' plugin has been changed to reflect
515 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
517 * The debugging system has been fixed to work with the Sun libc.
518 * When built without librrd the variable `operating_mode' could be
519 uninitialized. Thanks to David Elliot for reporting the bug.
521 2006-06-01, Version 3.9.3
522 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
523 operating systems also profit from the changes, but I wasn't able to
525 * Changed the build system to find the netinet-includes under FreeBSD
526 and therefore successfully build the `liboping' library there.
528 2006-05-09, Version 3.9.2
529 * Applied a patch to the `liboping' library. Due to a bug in the
530 sequence checking the `ping' plugin stopped working after
531 approximately 7.6 days.
533 2006-05-09, Version 3.8.5
534 * Applied a patch to the `liboping' library. Due to a bug in the
535 sequence checking the `ping' plugin stopped working after
536 approximately 7.6 days.
538 2006-04-21, Version 3.9.1
539 * Build issues with Solaris and possible other architectures have been
541 * Problems when building the `apache'-plugin without `libcurl' have
543 * A bug in the `ping' plugin has been fixed. Sorry folks.
545 2006-04-02, Version 3.9.0
546 * A plugin to monitor the Apache webserver has been added.
547 <http://httpd.apache.org/>
548 * A plugin to collect statistics about virtual servers using VServer.
549 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
551 * A plugin for wireless LAN cards has been added. It monitors signal
552 strength, link quality and noise ratio..
553 * A plugin for Apple hardware sensors has been added.
554 * An option to compile collectd with different `step' and `heartbeat'
555 settings has been added. The size of RRAs is no longer static but
556 calculated based on the settings for `step' and `width'.
557 * The `ping' plugin can now be configured to use a certain TTL.
558 * A plugin to monitor the hardware sensors of Apple computers has been
560 * The plugins `cpu', `memory', `processes' and `traffic' have been
561 ported to Mach/Darwin (Mac OS X).
562 * The `log mode' has been contributed by Christophe Kalt. It writes
563 the data into text files rather than RRD files.
565 2006-04-09, Version 3.8.4
566 * Applied patch by Vincent Stehlé which improves the disk-name
567 resolution in the `hddtemp' plugin for Linux systems.
569 2006-04-02, Version 3.8.3
570 * Applied a patch by James Byers: The MySQL plugin was not working
571 with MySQL 5.0.2 or later.
573 2006-03-14, Version 3.8.2
574 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
575 the GNU libc, because it points to `/etc/fstab' rather than
578 2006-03-13, Version 3.8.1
579 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
580 * Fixes in the debian `postinst' and `init.d' scripts.
582 2006-03-09, Version 3.8.0
583 * The `ping' plugin no longer uses `libping' but a self written
584 library named `liboping'. With this library it's possible to ping
585 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
587 2006-02-18, Version 3.7.2
588 * A simple bug in the `battery' plugin has been fixed. It should now
589 work with ACPI based batteries as well. Thanks to Sebastian for
591 * Fixing a bug that prevented collectd to be built without librrd.
592 Thanks to Werner Heuser for reporting it.
594 2006-02-04, Version 3.7.1
595 * The new network code has been improved to build with older versions
597 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
598 to Tommie Gannert for this patch.
600 2006-01-30, Version 3.7.0
601 * The `battery' plugin has been added. It collects information about
603 * The MySQL plugin has been improved: It now writes two more RRD
604 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
605 * The `cpufreq' plugin now reads another file since the file it did
606 read so far causes much overhead in the kernel. Also, you need root
607 to read the old file, but not to read the new one.
608 * The `hddtemp' plugin can now be configured to connect to another
609 address and/or port than localhost.
610 * The `df' plugin now prefers `statvfs' over `statfs'.
611 * The network code has been rewritten. collectd now supports unicast
612 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
613 be set in the configfile.
615 2006-01-24, Version 3.6.2
616 * Due to a bug in the configfile handling collectd wouldn't start in
617 client mode. This released fixes this.
619 2006-01-20, Version 3.6.1
620 * Due to a bug in `configure.in' all modules and the binary were
621 linked against `libmysqlclient'. This issue is solved by this
624 2006-01-17, Version 3.6.0
625 * A config file has been added. This allows for loading only specific
627 * A `df' plugin has been added.
628 * A `mysql' plugin has been added.
629 * The `ping' plugin doesn't entirely give up hope when a socket error
630 occurred, but will back of and increase the intervals between tries.
632 2006-01-21, Version 3.5.2
633 * Fixed yet another bug in the signal handling.. Stupid typo..
634 * Improved the ping plugin to not give up on socket errors (backport
637 2005-12-18, Version 3.5.1
638 * The PID-file is now deleted correctly when shutting down the daemon.
639 * SIGINT and SIGTERM are now handled correctly.
641 2005-12-16, Version 3.5.0 (Revision 326)
642 * A bug in the `load' module under Solaris has been fixed.
643 * The `users' module has been contributed by Sebastian Harl. It counts
644 currently logged in users.
645 * The CPU module now works under FreeBSD without the use of
646 `libstatgrab', however SMP support is missing.
647 * The default directories for the RRD files and the PID file now
648 depend on the compile time setting of `localstatedir'.
650 2005-11-15, Version 3.4.0 (Revision 236)
651 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
652 from gentoo's bugzilla for writing the patch.
653 * The build dependency for librrd has been removed. Binaries built
654 without librrd are client-only and will multicast their value as
655 with the `-c' argument.
656 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
657 * The newly introduced `-f' switch prevents daemon initialization
658 (forking, closing standard filehandles, etc.) Thanks to Alvaro
659 Barcellos for this patch.
661 2005-11-04, Version 3.3.0 (Revision 216)
662 * New modules have been added:
663 - `serial', for monitoring traffic on the serial interfaces
664 - `nfs', for graphing NFS procedure calls
665 - `tape', traffic from/to tape devices
666 * The memory.rrd now accepts more than 4Gig of memory.
668 2005-10-26, Version 3.2.0 (Revision 200)
669 * Support for graphing the processes has been added (thanks to Lyonel
671 * If reading from hddtemp fails collectd will increase the time
672 between polls up to one day.
673 * The init.d files have been improved.
674 * Problems with the spec file have been fixed.
676 2005-10-16, Version 3.1.0 (Revision 194)
677 * Added the `setsid' syscall to the startup code.
678 * Support for hddtemp has been added (thanks to Vincent Stehlé)
680 2005-09-30, Version 3.0.0 (Revision 184)
681 * The ability to send/receive data to/from the network (think
682 multicast) has been added.
683 * Modules have been split up into shared libraries can be loaded at
684 runtime. The biggest advantage is that the core program doesn't need
685 to be linked against an external library.
686 * A patch by George Kargiotakis has been applied: It fixes the sensors
687 behaviour then more than one sensor is being queried.
689 2005-09-16, Version 2.1.0 (Revision 172)
690 * A module for swap statistics has been added.
692 2005-09-09, Version 2.0.0 (Revision 135)
693 * Filenames can no longer be configured at program startup. The only
694 options as of this version are the directory and ping hosts.
695 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
696 Soft-IRQ statistics are added to `System'.
697 * Diskstats now collect read and write bytes, not sectors.
698 * Ping statistics can now be collected for more than one host. There
699 is no default any more: If no host is given no host will be pinged.
700 * A self-written patch for libping has been applied so it builds
703 2005-09-01, Version 1.8.1 (Revision 123)
704 * Much improved configure-script: libraries and features may now be
706 * More detailed warnings/error messages when RRD update fails.
708 2005-08-29, Version 1.8.0:
709 * Support for collecting disk statistics under Solaris.
711 2005-08-25, Version 1.7.0:
712 * Support for libstatgrab[1] for load, memory usage and network
713 traffic. CPU- and disk-usage are not (yet) supported, since
714 libstatgrab returns insufficient information. I will contact the
716 * Improved the CPU-initialization code for Solaris. Apparently CPUs
717 aren't necessarily counted linear which is now handled correctly.
718 [1]: http://www.i-scream.org/libstatgrab/
720 2005-08-21, Version 1.6.0:
721 * Basic support for Solaris: System load and cpu-usage can be
722 collected under Solaris, too. Other stats will follow later.
723 * Many fixes in the autoconf-script
724 * Collection/Museum scripts have been added under contrib/museum
725 * collectd may now be started in unprivileged mode, though ping
726 statistics will not work.
728 2005-07-17, Version 1.5.1:
729 * Diskstats-RRDs now use major/minor for naming. Some systems have
730 weird strings as disk-names..
732 2005-07-17, Version 1.5:
733 * A new module, diskstats, has been added. It collects information
734 about the disks and partitions.
736 2005-07-11, Version 1.4.2:
737 * The meminfo module has been changed to work with more platforms
738 and/or kernel versions.
740 2005-07-10, Version 1.4.1: Correct traffic stats
741 * The traffic rrd-file is now created with DS-type `COUNTER' which I
742 forgot to correct when I changed that module.
744 2005-07-09, Version 1.4: More traffic stats
745 * Traffic is now collected for all interfaces that can be found
746 * Temperature-statistics are read from lm-sensors if available
748 2005-07-08, Version 1.3: CPU stats
749 * Collecting CPU statistics now
751 2004-07-12, Version 1.2: Using syslog
752 * collectd is now using the syslog facility to report errors, warnings
754 * The default directory is now /var/db/collectd
756 2004-07-10, Version 1.1: Minor changes
757 * Nothing really useful to say ;)
759 2004-07-09, Version 1.0: Initial Version
760 * The following modules are provided:
