3 * collectd: The concept of `notification meta data' has been
4 introduced.
5 * filecount plugin: The new filecount plugin counts the number of
6 files in a directory and its subdirectories.
7 * ipmi plugin: Sensor names have been changed to ensure unique names.
8 Notifications upon added and removed sensors can now be generated.
9 * notify_desktop plugin: This new plugin sends notifications to the
10 X desktop using the structure defined in the `Desktop Notification
11 Specification'.
12 * notify_email plugin: This new plugin sends out notifications via
13 email, using the `esmtp' library.
14 * postgresql plugin: The new postgresql plugin collects statistics
15 from an PostgreSQL database.
16 * processes plugin: The `ProcessMatch' option has been added.

23 and fixed a possible dead-lock.
24 * perl plugin: Added the ability to flush certain identifiers and marked
25 plugin_flush_all() and plugin_flush_one() as deprecated in favor of
26 plugin_flush().
27 * TODO: onewire plugin?
29 2008-07-15, Version 4.4.2
30 * build system: Use pkg-config to detect the upsclient library.
31 * collectd: Try even harder to determine the endianess of the
32 architecture collectd is being built on.
33 * disk plugin: Fix for Linux 2.4: A wrong field was used as the name
34 of disks.
35 * dns plugin: Fix compilation errors with BIND versions 19991001
36 through 19991005.
37 * network plugin: Bugfix in the init routine: The init function
38 cleared a buffer regardless of its contents. This could lead to lost
39 values under Solaris.
40 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
41 * vserver plugin: Remove usage of the thread-unsafe `readdir'
42 function.
43 * wireless plugin: Work around incorrect noise and power values
44 returned by some broken drivers.
46 2008-06-03, Version 4.4.1

56 René Rebe and Siegmund Gorr for reporting this.
58 2008-05-06, Version 4.4.0
59 * collectd: Internal code cleanups.
60 * collectd: Added support for a `Flush' command in the unixsock and
61 exec plugins. This command can be used to force a plugin (or all) to
62 flush its values to disk.
63 * collectd: Thresholds can now be configured to apply to one data
64 source only, making it possible to configure different thresholds
65 for each data source.
66 * apache, nginx plugins: Added the possibility to disable host and/or
67 peer verification.
68 * ascent plugin: The new ascent plugin reads and parses the statistics
69 page of an Ascent server.
70 * cpu plugin: Support for the statgrab library has been added.
71 * disk plugin: The possibility to ignore certain disks or collect only
72 specific disks has been added.
73 * disk plugin: Support for the statgrab library has been added.
74 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
75 sensor values via IPMI, the intelligent platform management
76 interface.
77 * iptables plugin: The iptc library that is used by the iptables
78 plugin has been added to the distribution, because it is not
79 provided by all distributions and removed from at least one.
80 * powerdns plugin: The new powerdns plugin reads statistics from an
81 authoritative or a recursing PowerDNS name server.
82 * rrdtool plugin: The size of the files generated with the default
83 configuration has been decreased.

94 * build system: Improved detection of several libraries, especially if
95 they are in non-standard paths.
96 * build system: Portability fixes: Automatically define "_REENTRANT"
97 if the libc expects it.
98 * collectd: Error and warning messages have been improved.
99 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
100 using them.
101 * apache plugin: Allocate new memory when reading a webpage instead of
102 using a buffer of static size.
103 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
104 the program.
105 * hddtemp plugin: Error and warning messages have been improved.
106 * sensors plugin: Fix sensor collection for some chip types.
108 2008-03-29, Version 4.3.2
109 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
110 `Persist' threshold options.
111 * collectd: Fix handling of missing values in the global value cache.
112 * collectd: Improved error messages when parsing the configuration.
113 * sensors plugin: Fix temperature collection with libsensors4.
114 * unixsock plugin: Fix mixed input and output operation on streams.
115 * wireless plugin: Fix reading noise value.
117 2008-03-05, Version 4.3.1
118 * exec plugin: Set supplementary group IDs.
119 * network plugin:
120 + Use `memcpy' when constructing/parsing a package to avoid
121 alignment problems on weird architectures, such as Sparc.
122 + Translate doubles to/from the x86 byte representation to ensure
123 cross-platform compatibility.
124 * ping plugin: Correct the handling of the `TTL' setting.
125 * swap plugin: Reapply a patch for Solaris.
126 * tcpconns plugin: Portability improvements.
128 2008-02-18, Version 4.3.0
129 * collectd: Notifications have been added to the daemon. Notifications
130 are status messages that may be associated with a data instance.
131 * collectd: Threshold checking has been added to the daemon. This
132 means that you can configure threshold values for each data
133 instance. If this threshold is exceeded a notification will be
134 created.
135 * collectd: The new `FQDNLookup' option tells the daemon to use the
136 full qualified domain name as the hostname, not just the host part
137 es returned by `gethostname(2)'.
138 * collectd: Support for more than one `TypesDB' file has been added.
139 This is useful when one such file is included in a package but one
140 wants to add custom type definitions.
141 * collectd: The `Include' config option has been expanded to handle
142 entire directories and shell wildcards.
143 * collectdmon: The new `collectdmon' binary detects when collectd
144 terminates and automatically restarts it again.
145 * csv plugin: The CSV plugin is now able to store counter values as a
146 rate, using the `StoreRates' configuration option.
147 * exec plugin: Handling of notifications has been added and the
148 ability to pass arguments to the executed programs has been added.
149 * hddtemp plugin: The new `TranslateDevicename' option lets you
150 disable the translation from device names to major-minor-numbers.
151 * logfile plugin: Handling of notifications has been added.
152 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
153 domain name lookups in this plugin.
154 * perl plugin: Many internal changes added support for handling multiple
155 threads making the plugin reasonably usable inside collectd. The API has
156 been extended to support notifications and export global variables to
157 Perl plugins; callbacks now have to be identified by name rather than a
158 pointer to a subroutine. The plugin is no longer experimental.
159 * uuid plugin: The new UUID plugin sets the hostname to an unique
160 identifier for this host. This is meant for setups where each client
161 may migrate to another physical host, possibly going through one or
162 more name changes in the process. Thanks to Richard Jones from
163 Red Hat's Emerging Technology group for this plugin.
164 * libvirt: The new libvirt plugin uses the `libvirt' library to query
165 CPU, disk and network statistics about guest systems on the same
166 physical server. Thanks to Richard Jones from Red Hat's Emerging
167 Technology group for this plugin.
169 2008-04-22, Version 4.2.7
170 * build system: Improved detection of several libraries, especially if
171 they are in non-standard paths.
172 * build system: Portability fixes: Automatically define "_REENTRANT"
173 if the libc expects it.
174 * collectd: Error and warning messages have been improved.
175 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
176 using them.
177 * apache plugin: Allocate new memory when reading a webpage instead of
178 using a buffer of static size.
179 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
180 the program.
181 * hddtemp plugin: Error and warning messages have been improved.
182 * sensors plugin: Fix sensor collection for some chip types.
184 2008-03-29, Version 4.2.6
185 * collectd: Improved error messages when parsing the configuration.
186 * sensors plugin: Fix temperature collection with libsensors4.
187 * unixsock plugin: Fix mixed input and output operation on streams.
188 * wireless plugin: Fix reading noise value.
190 2008-03-04, Version 4.2.5
191 * apache plugin: Improved initialization and error messages.
192 * exec plugin: Set supplementary group IDs.
193 * network plugin:
194 + Create separate threads for reading from the socket and parsing
195 and dispatching incoming packets. Versions prior to this may have
196 problems in high-load situations, where the socket receive buffers
197 overflows, resulting in gaps in the data.
198 + Use `memcpy' when constructing/parsing a package to avoid
199 alignment problems on weird architectures, such as Sparc.
200 + Translate doubles to/from the x86 byte representation to ensure
201 cross-platform compatibility.
202 * ping plugin: Correct the handling of the `TTL' setting.
203 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
204 * swap plugin: Reapply a patch for Solaris.
205 * tcpconns plugin: Portability improvements.
207 2008-01-21, Version 4.2.4
208 * unixsock plugin: A bug in the unixsock plugin caused it not to set
209 the permission on the socket as documented in the manpage. Thanks to
210 Evgeny Chukreev for fixing this issue.
211 * collectd: The documentation has been improved.
213 2007-12-28, Version 4.2.3
214 * sensors plugin: Updated the plugin to build and work with version 3
215 of the libsensors library.
217 2007-12-15, Version 4.2.2
218 * nginx plugin: Incorrect comparison of strings lead to a segfault
219 when using the plugin. Thanks to Saulius Grigaliunas for fixing
220 this.
221 * logfile plugin: The config option `Timestamp' was handled
222 incorrectly and basically always active. Thanks to Luke Heberling
223 for fixing this.
225 2007-11-08, Version 4.2.1
226 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
227 enabled on the host.
228 * snmp plugin: Fix a memory leak.
230 2007-10-27, Version 4.2.0
231 * collectd: The new config option `Include' lets you include other
232 configfiles and thus split up your config into smaller parts. This
233 may be especially interesting for the snmp plugin to keep the data
234 definitions separate from the host definitions.
235 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
236 (number of connections, octets and packets for each service and
237 destination). Thanks to Sebastian Harl for this plugin.
238 * memcached plugin: The new `memcached' plugin connects to a memcached
239 daemon process and collects statistics of this distributed caching
240 system. Thanks to Antony Dovgal for contributing this plugin.
241 * nginx plugin: The new `nginx' plugin reads the status page of an
242 nginx daemon and saves the handled connections and requests.
243 * perl plugin: Many changes, including the added `EnableDebugger'
244 config option which lets you debug your Perl plugins more easily.
245 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
246 be more thread-safe otherwise by locking calls to the library.
247 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
248 correct the values returned by SNMP-agents. If a <data> block is
249 defined as `table' the instance is now optional. The sequence number
250 is used as the type-instance in this case. The new `InstancePrefix'
251 option allows to add arbitrary prefixes to the type-instance.
252 * tcpconns plugin: The new `tcpconns' plugin collects the number of
253 certain TCP connections and what state they're in. This can be used
254 to see how many connections your FTP server has to handle or how
255 many outgoing connections your mailserver has open.
257 2008-01-11, Version 4.1.6
258 * unixsock plugin: A bug in the unixsock plugin caused it not to set
259 the permission on the socket as documented in the manpage. Thanks to
260 Evgeny Chukreev for fixing this issue.
261 * collectd: The documentation has been improved.
263 2007-12-27, Version 4.1.5
264 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
265 memory situations.

267 of the libsensors library.
269 2007-11-08, Version 4.1.4
270 * Build system: Improve detection of the rrd library, especially if
271 it's in a non-standard location.
272 * Build system: A bug when parsing the argument for
273 `--with-libnetsnmp' has been fixed.
274 * collectd: Implement `strerror_r' if the libc doesn't provide it.
275 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
276 a deadlock or delay when shutting down the daemon.
277 * snmp plugin: Fix a memory leak.
279 2007-10-24, Version 4.1.3
280 * collectd: A build issue under Solaris has been resolved by renaming
281 data types.
282 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
283 be more thread-safe otherwise by locking calls to the library.
285 2007-09-28, Version 4.1.2
286 * apcups plugin: Fix reporting of the `load percent' data.
287 * wireless plugin: Correct the handling of cards returning signal and
288 noise quality as percentage.
289 * perl plugin: Fix a possible buffer overflow in get_module_name().
290 * build system: Further improve the detection of libraries.
291 * netlink plugin: Build issues under some older versions of the Linux
292 includes (i. e. Debian Sarge) have been fixed.
293 * snmp plugin: Fix a potential segfault when a host times out. Add
294 support for the `timeticks' type.
296 2007-09-12, Version 4.1.1
297 * Build system: The detection of `libnetlink' has been improved.
298 * collectd: The documentation has been fixed in numerous places.
299 * exec plugin: Setting the group under which to run a program has been
300 fixed.
301 * collectd: The `sstrerror' function was improved to work correctly
302 with the broken GNU version of `strerror_r'.
303 * collectd: Write an error message to STDERR when loading of a plugin
304 fails.
305 * apcups plugin: Fix the `types' used to submit the values: They still
306 has an `apcups_' prefix which doesn't work anymore.
307 * rrdtool plugin: Create new RRD-files with the `begin' time set to
308 whatever the client thinks is `now'..
310 2007-09-01, Version 4.1.0
311 * Build system: The build system has been changed to automatically
312 disable all plugins, which are missing dependencies. The dependency
313 checking has been removed from the plugins themselves to remove
314 redundancy.
315 * Flexible interval: The interval of collected data is now sent along
316 with the data itself over the network, so that the interval-settings
317 of server and clients no longer needs to match.
318 * netlink plugin: The new `netlink' plugin connects to the Linux
319 kernel using a netlink socket and uses it to query information about
320 interfaces, qdiscs and classes.
321 * rrdtool plugin: The cache is now dumped to disk in an extra thread
322 to not block data collection.
323 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
324 network devices, such as switches, routers, thermometers, rack
325 monitoring servers, etc. The collectd-snmp(5) manpage documents this
326 plugin.
327 * unixsock plugin: Added the `LISTVAL' command.
328 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
329 of music played with xmms.
331 2007-09-28, Version 4.0.9
332 * apcups plugin: Fix reporting of the `load percent' data.
333 * wireless plugin: Correct the handling of cards returning signal and
334 noise quality as percentage.
335 * perl plugin: Fix a possible buffer overflow in get_module_name().
337 2007-09-12, Version 4.0.8
338 * collectd: The `sstrerror' function was improved to work correctly
339 with the broken GNU version of `strerror_r'.
340 * collectd: Write an error message to STDERR when loading of a plugin
341 fails.
342 * apcups plugin: Fix the `types' used to submit the values: They still
343 has an `apcups_' prefix which doesn't work anymore.
344 * rrdtool plugin: Create new RRD-files with the `begin' time set to
345 whatever the client thinks is `now'..
347 2007-08-26, Version 4.0.7
348 * documentation: Some typos have been fixed and some information has
349 been improved.
350 * build system: Many fixes for detecting libraries in unusual places,
351 such as on RedHat systems. The affected libraries are `libcurl',
352 `libmysql', and `libupsclient'.
353 * network plugin: Allow the `Port' option to be specified as a number
354 (i. e. without quotes).
355 * nut plugin: A fix allows linking the nut plugin against
356 libupsclient, version >= 2.2.0.
357 * processes plugin: Fix a potential segmentation fault.
359 2007-07-30, Version 4.0.6
360 * sensors plugin: Fix the ignorelist functionality: Only the `type
361 instance' was used to match against the list, but the documentation
362 told otherwise. This release fixes the code, so it complies with the
363 documentation.
364 * syslog plugin: Call `openlog' right when the plugin is loaded, so
365 configuration messages will end up in the logging facility.
366 * conrtib/fedora: The contributed specfile for Fedora has been
367 updated.
369 2007-07-05, Version 4.0.5
370 * Portability: More fixes for OpenBSD have been included.
372 2007-06-24, Version 4.0.4
373 * cpu plugin: Fixed the Solaris code.
374 * dns plugin: Fixed a build issue for OpenBSD.
375 * interface plugin: Fixed the Solaris code.
376 * load plugin: Fixed the alternative `/proc' Linux code.
377 * memory plugin: Fixed the Solaris code.
378 * oconfig: Don't require `-lfl' anymore.
380 2007-06-19, Version 4.0.3
381 * cpu plugin: Fix the Darwin / Mac OS X code.
382 * ping plugin: Use the return value of `getpid', not its address.
383 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
384 initialized correctly.
385 * configure: Added `--with-nan-emulation' to aid cross compilation.
387 2007-06-12, Version 4.0.2
388 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
389 they're given in numerically form.
391 2007-06-07, Version 4.0.1
392 * iptables plugin: A bug in the configuration routine has been fixed.
393 Setting a comment in the configfile will no longer cause a
394 segmentation fault.
396 2007-06-03, Version 4.0.0
397 * collectd: The plugin-infrastructure has been changed to allow for
398 more types of plugins, namely `write' and `log' plugins.
399 * collectd: The read-function has been changed to read many plugins in
400 parallel, using threads. Thus, plugins generally need to use
401 thread-safe functions from now on.
402 * collectd: The '-t' command line options allows to perform syntax tests
403 of the configuration file and exit immediately.
404 * csv plugin: The new `csv' plugin handles output to `comma separated
405 values'-files.
406 * rrdtool plugin: The new `rrdtool' plugin handles output to
407 RRD-files. Data can be cached to combine multiple updates into one
408 write to increase IO-performance.
409 * network plugin: The new `network' plugin handles IO via the network.
410 It implements a different, much more extensible protocol which can
411 combine many values in one packet, decreasing the number of UDP-
412 packets being sent. It can read from and send to the network and
413 with the appropriate configuration even forward packets to other
414 networks.
415 * unixsock plugin: The new `unixsock' plugin provides an interface to
416 communicate with the daemon while it is running. Right now the
417 commands `GETVAL' and `PUTVAL' are implemented, but more are to
418 come.
419 * perl plugin: The new `perl' plugin allows you to write extensions
420 for collectd in the scripting-language Perl.
421 * logfile plugin: The new `logfile' plugin writes logmessages to files
422 or STDOUT or STDERR.
423 * syslog plugin: The new `syslog' plugin sends logmessages to the
424 system's syslog daemon.
425 * entropy plugin: The new `entropy' plugin collects the amount of
426 entropy currently being available to the system.
427 * exec plugin: The new `exec' plugin forks child processes and reads
428 back values provided by the forked processes.
429 * iptables plugin: The new `iptables' plugin reads counters from
430 iptables rules. Thanks to Sjoerd van der Berg for contributing this
431 plugin.
432 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
433 to Peter Holik for contributing this plugin.
434 * nut plugin: The new `nut' plugin connects the upsd of the `network
435 ups tools' and reads information about the connected UPS.
436 * apache plugin: Support for lighttpd's `BusyServers' (aka.
437 connections) field was added by Florent Monbillard.
438 * collectd-nagios: The new `collectd-nagios' binary queries values
439 from collectd, parses them and exits according to Nagios-standards.
440 * manpages: The manpages have been improved a lot.
442 2007-09-28, Version 3.11.7
443 * wireless plugin: Correct the handling of cards returning signal and
444 noise quality as percentage.
446 2007-08-31, Version 3.11.6
447 * processes plugin: Fix a potential segmentation fault.
449 2007-05-29, Version 3.11.5
450 * configure: Added `AC_SYS_LARGEFILE' for LFS.
451 * ntpd plugin: Fix a potential buffer overflow.
452 * processes plugin: Fix a bug when run under Linux 2.4. All processes
453 were accounted as `zombies'.
455 2007-04-10, Version 3.11.4
456 * dns plugin: Change the order of includes to make the plugin compile
457 under FreeBSD.
459 2007-03-30, Version 3.11.3
460 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
461 of the unused `COLLECT_KSTAT'.
463 2007-02-11, Version 3.11.2
464 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
465 NULL-pointer may have been passed to `printf' which causes a
466 segfault with some libcs.
468 2007-02-10, Version 3.11.1
469 * df plugin: Some wrong defines have been fixed so the plugin works
470 under Solaris again.
471 * dns plugin: The usage of a struct has been fixed to work with
472 non-GNU libcs.
473 * processes plugin: Some missing defines have been added so the plugin
474 compiles cleanly under FreeBSD and presumably other UNIXes.
476 2006-12-22, Version 3.11.0
477 * collectd: The new command line option `-P' makes it easier for
478 distributors to change the location of PID-files.
479 * collectd: The daemon shuts down faster now which makes it easier to
480 write init.d-scripts for it.
481 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
482 caused problems every now and then.
483 * df plugin: New config options allow to ignore certain mountpoints,
484 filesystem types or devices.
485 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
486 and interprets it. It collects traffic as well as qtype, opcode and
487 rcode counts.
488 * email plugin: Sebastian Harl has contributed this plugin which
489 counts received mails in categories (e. g. ham, spam, virus), spam
490 score (as given by SpamAssassin) and check types.
491 * mbmon plugin: Flavio Stanchina has contributed this plugin which
492 uses `mbmon' to gather information from sensors on the motherboard.
493 * processes plugin: Collect detailed statistics for configured
494 processes, that's process and thread count, CPU usage, resident
495 segment size and pagefaults.
496 * multimeter plugin: Peter Holik contributed a new plugin which
497 queries multimeters.
498 * sensors plugin: Lubos Stanek has put much effort into improving this
499 plugin, including `extended naming', collection of voltage values
500 and the possibility to ignore certain values.
502 2006-12-21, Version 3.10.4
503 * Max Kellermann has identified a bug in the server routine: When
504 opening a socket fails the daemon will (re)try opening the socket in
505 an endless loop, ultimately leading to a `EMFILE' error.
507 2006-11-04, Version 3.10.3
508 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
509 ntpd's reply was sent in more than one packet, the buffer size was
510 calculated incorrectly, resulting in the reading of uninitialized or
511 freed memory.
513 2006-11-01, Version 3.10.2
514 * The sample config file has been improved.
515 * Errors in the manpages have been corrected.
516 * The ping-plugin now adds hosts during initialization, not during
517 startup. This speeds up startup when no network connectivity is
518 available. Also, the hosts are being added later when the network is
519 available.
520 * Improved BSD-support for the df-plugin.
521 * Fixed syntax errors in the swap-plugin for Mac OS X.
522 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
523 plugin.
524 * Don't disable the mysql-plugin if connecting to the database fails
525 during initialization. Instead, try again in increasing intervals.
527 2006-07-19, Version 3.10.1
528 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
529 the apcups cannot be reached, unconnected sockets will pile up and
530 eventually lead to `Too many open files' errors.
532 2006-07-09, Version 3.10.0
533 * The `disk' plugin has been ported to Darwin.
534 * The `battery' plugin should work on many Apple computers now.
535 * The `traffic' plugin can now ignore certain interfaces. Also,
536 statistics for sent/received packets and errors have been added.
537 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
538 to Anthony Gialluca for contributing this plugin and providing me
539 with a test environment :)
540 * A plugin for monitoring an NTP instance and the local clock drift
541 has been added.
543 2006-06-25, Version 3.9.4
544 * The Solaris code in the `swap' plugin has been changed to reflect
545 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
546 working this out.
547 * The debugging system has been fixed to work with the Sun libc.
548 * When built without librrd the variable `operating_mode' could be
549 uninitialized. Thanks to David Elliot for reporting the bug.
551 2006-06-01, Version 3.9.3
552 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
553 operating systems also profit from the changes, but I wasn't able to
554 check that.
555 * Changed the build system to find the netinet-includes under FreeBSD
556 and therefore successfully build the `liboping' library there.
558 2006-05-09, Version 3.9.2
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 2006-05-09, Version 3.8.5
564 * Applied a patch to the `liboping' library. Due to a bug in the
565 sequence checking the `ping' plugin stopped working after
566 approximately 7.6 days.
568 2006-04-21, Version 3.9.1
569 * Build issues with Solaris and possible other architectures have been
570 resolved.
571 * Problems when building the `apache'-plugin without `libcurl' have
572 been resolved.
573 * A bug in the `ping' plugin has been fixed. Sorry folks.
575 2006-04-02, Version 3.9.0
576 * A plugin to monitor the Apache webserver has been added.
577 <http://httpd.apache.org/>
578 * A plugin to collect statistics about virtual servers using VServer.
579 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
580 this plugin :)
581 * A plugin for wireless LAN cards has been added. It monitors signal
582 strength, link quality and noise ratio..
583 * A plugin for Apple hardware sensors has been added.
584 * An option to compile collectd with different `step' and `heartbeat'
585 settings has been added. The size of RRAs is no longer static but
586 calculated based on the settings for `step' and `width'.
587 * The `ping' plugin can now be configured to use a certain TTL.
588 * A plugin to monitor the hardware sensors of Apple computers has been
589 added.
590 * The plugins `cpu', `memory', `processes' and `traffic' have been
591 ported to Mach/Darwin (Mac OS X).
592 * The `log mode' has been contributed by Christophe Kalt. It writes
593 the data into text files rather than RRD files.
595 2006-04-09, Version 3.8.4
596 * Applied patch by Vincent Stehlé which improves the disk-name
597 resolution in the `hddtemp' plugin for Linux systems.
599 2006-04-02, Version 3.8.3
600 * Applied a patch by James Byers: The MySQL plugin was not working
601 with MySQL 5.0.2 or later.
603 2006-03-14, Version 3.8.2
604 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
605 the GNU libc, because it points to `/etc/fstab' rather than
606 `/etc/mtab'.
608 2006-03-13, Version 3.8.1
609 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
610 * Fixes in the debian `postinst' and `init.d' scripts.
612 2006-03-09, Version 3.8.0
613 * The `ping' plugin no longer uses `libping' but a self written
614 library named `liboping'. With this library it's possible to ping
615 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
617 2006-02-18, Version 3.7.2
618 * A simple bug in the `battery' plugin has been fixed. It should now
619 work with ACPI based batteries as well. Thanks to Sebastian for
620 fixing this.
621 * Fixing a bug that prevented collectd to be built without librrd.
622 Thanks to Werner Heuser for reporting it.
624 2006-02-04, Version 3.7.1
625 * The new network code has been improved to build with older versions
626 of glibc.
627 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
628 to Tommie Gannert for this patch.
630 2006-01-30, Version 3.7.0
631 * The `battery' plugin has been added. It collects information about
632 laptop batteries..
633 * The MySQL plugin has been improved: It now writes two more RRD
634 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
635 * The `cpufreq' plugin now reads another file since the file it did
636 read so far causes much overhead in the kernel. Also, you need root
637 to read the old file, but not to read the new one.
638 * The `hddtemp' plugin can now be configured to connect to another
639 address and/or port than localhost.
640 * The `df' plugin now prefers `statvfs' over `statfs'.
641 * The network code has been rewritten. collectd now supports unicast
642 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
643 be set in the configfile.
645 2006-01-24, Version 3.6.2
646 * Due to a bug in the configfile handling collectd wouldn't start in
647 client mode. This released fixes this.
649 2006-01-20, Version 3.6.1
650 * Due to a bug in `configure.in' all modules and the binary were
651 linked against `libmysqlclient'. This issue is solved by this
652 release.
654 2006-01-17, Version 3.6.0
655 * A config file has been added. This allows for loading only specific
656 plugins.
657 * A `df' plugin has been added.
658 * A `mysql' plugin has been added.
659 * The `ping' plugin doesn't entirely give up hope when a socket error
660 occurred, but will back of and increase the intervals between tries.
662 2006-01-21, Version 3.5.2
663 * Fixed yet another bug in the signal handling.. Stupid typo..
664 * Improved the ping plugin to not give up on socket errors (backport
665 from 3.6.0).
667 2005-12-18, Version 3.5.1
668 * The PID-file is now deleted correctly when shutting down the daemon.
669 * SIGINT and SIGTERM are now handled correctly.
671 2005-12-16, Version 3.5.0 (Revision 326)
672 * A bug in the `load' module under Solaris has been fixed.
673 * The `users' module has been contributed by Sebastian Harl. It counts
674 currently logged in users.
675 * The CPU module now works under FreeBSD without the use of
676 `libstatgrab', however SMP support is missing.
677 * The default directories for the RRD files and the PID file now
678 depend on the compile time setting of `localstatedir'.
680 2005-11-15, Version 3.4.0 (Revision 236)
681 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
682 from gentoo's bugzilla for writing the patch.
683 * The build dependency for librrd has been removed. Binaries built
684 without librrd are client-only and will multicast their value as
685 with the `-c' argument.
686 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
687 * The newly introduced `-f' switch prevents daemon initialization
688 (forking, closing standard filehandles, etc.) Thanks to Alvaro
689 Barcellos for this patch.
691 2005-11-04, Version 3.3.0 (Revision 216)
692 * New modules have been added:
693 - `serial', for monitoring traffic on the serial interfaces
694 - `nfs', for graphing NFS procedure calls
695 - `tape', traffic from/to tape devices
696 * The memory.rrd now accepts more than 4Gig of memory.
698 2005-10-26, Version 3.2.0 (Revision 200)
699 * Support for graphing the processes has been added (thanks to Lyonel
700 Vincent)
701 * If reading from hddtemp fails collectd will increase the time
702 between polls up to one day.
703 * The init.d files have been improved.
704 * Problems with the spec file have been fixed.
706 2005-10-16, Version 3.1.0 (Revision 194)
707 * Added the `setsid' syscall to the startup code.
708 * Support for hddtemp has been added (thanks to Vincent Stehlé)
710 2005-09-30, Version 3.0.0 (Revision 184)
711 * The ability to send/receive data to/from the network (think
712 multicast) has been added.
713 * Modules have been split up into shared libraries can be loaded at
714 runtime. The biggest advantage is that the core program doesn't need
715 to be linked against an external library.
716 * A patch by George Kargiotakis has been applied: It fixes the sensors
717 behaviour then more than one sensor is being queried.
719 2005-09-16, Version 2.1.0 (Revision 172)
720 * A module for swap statistics has been added.
722 2005-09-09, Version 2.0.0 (Revision 135)
723 * Filenames can no longer be configured at program startup. The only
724 options as of this version are the directory and ping hosts.
725 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
726 Soft-IRQ statistics are added to `System'.
727 * Diskstats now collect read and write bytes, not sectors.
728 * Ping statistics can now be collected for more than one host. There
729 is no default any more: If no host is given no host will be pinged.
730 * A self-written patch for libping has been applied so it builds
731 cleanly.
733 2005-09-01, Version 1.8.1 (Revision 123)
734 * Much improved configure-script: libraries and features may now be
735 disabled.
736 * More detailed warnings/error messages when RRD update fails.
738 2005-08-29, Version 1.8.0:
739 * Support for collecting disk statistics under Solaris.
741 2005-08-25, Version 1.7.0:
742 * Support for libstatgrab[1] for load, memory usage and network
743 traffic. CPU- and disk-usage are not (yet) supported, since
744 libstatgrab returns insufficient information. I will contact the
745 authors.
746 * Improved the CPU-initialization code for Solaris. Apparently CPUs
747 aren't necessarily counted linear which is now handled correctly.
748 [1]: http://www.i-scream.org/libstatgrab/
750 2005-08-21, Version 1.6.0:
751 * Basic support for Solaris: System load and cpu-usage can be
752 collected under Solaris, too. Other stats will follow later.
753 * Many fixes in the autoconf-script
754 * Collection/Museum scripts have been added under contrib/museum
755 * collectd may now be started in unprivileged mode, though ping
756 statistics will not work.
758 2005-07-17, Version 1.5.1:
759 * Diskstats-RRDs now use major/minor for naming. Some systems have
760 weird strings as disk-names..
762 2005-07-17, Version 1.5:
763 * A new module, diskstats, has been added. It collects information
764 about the disks and partitions.
766 2005-07-11, Version 1.4.2:
767 * The meminfo module has been changed to work with more platforms
768 and/or kernel versions.
770 2005-07-10, Version 1.4.1: Correct traffic stats
771 * The traffic rrd-file is now created with DS-type `COUNTER' which I
772 forgot to correct when I changed that module.
774 2005-07-09, Version 1.4: More traffic stats
775 * Traffic is now collected for all interfaces that can be found
776 * Temperature-statistics are read from lm-sensors if available
778 2005-07-08, Version 1.3: CPU stats
779 * Collecting CPU statistics now
781 2004-07-12, Version 1.2: Using syslog
782 * collectd is now using the syslog facility to report errors, warnings
783 and the like..
784 * The default directory is now /var/db/collectd
786 2004-07-10, Version 1.1: Minor changes
787 * Nothing really useful to say ;)
789 2004-07-09, Version 1.0: Initial Version
790 * The following modules are provided:
791 * Load average
792 * Ping time
793 * Traffic
794 * Memory info
