1 2008-10-16, Version 4.4.4
2 * build system: Change `--enable-<plugin>' to abort with an error if
3 dependencies are not met. Thanks to Bruno Prémont for the patch.
4 Also, the poisoning of various string functions has been restricted
5 to debug builds.
6 * collectd: Fix a memory leak in the global value cache. With every
7 *missing* value a couple of bytes would be leaked. Another memory
8 leak in the configuration handling code has been fixed. Thanks to
9 Niraj Tolia for reporting these issues.
10 * collectd: Fix an off-by-one error in the ignorelist functionality.
11 When using regular expressions, the last character would be missing,
12 possibly matching differently from what one would expect.
13 * collectdmon: Don't block SIGCHLD. This fixes a potential portability
14 problem.
15 * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
16 Linzberger for reporting the bug.
17 * network plugin: Fix a memory leak in the configuration handling
18 code. Thanks to Niraj Tolia for reporting this issue.
19 * perl plugin: Log an error message if bootstrapping `Collectd' fails.
20 * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
21 problems with some `libc's. Thanks to Matthias Lay for reporting the
22 bug.
24 2008-09-01, Version 4.4.3
25 * collectd: Fix a memory leak in the threshold checking code.
26 * memcached plugin: Fix a too short timeout and a related file
27 descriptor leak.
28 * memory plugin: A typo in the libstatgrab code has been fixed.
29 * snmp plugin: Fix a possible memory leak.
31 2008-07-15, Version 4.4.2

36 of disks.
37 * dns plugin: Fix compilation errors with BIND versions 19991001
38 through 19991005.
39 * network plugin: Bugfix in the init routine: The init function
40 cleared a buffer regardless of its contents. This could lead to lost
41 values under Solaris.
42 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
43 * vserver plugin: Remove usage of the thread-unsafe `readdir'
44 function.
45 * wireless plugin: Work around incorrect noise and power values
46 returned by some broken drivers.
48 2008-06-03, Version 4.4.1
49 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
50 to kyrone for reporting this.
51 * collectd: Fixed min/max output in notifications generated by
52 threshold checking.
53 * collectd-nagios: Fix the protocol used to communicate with the
54 daemon.
55 * perl plugin: Fail noisily, but don't shutdown the daemon, if
56 initialization has errors. An issue with Perl 5.10 has been fixed.
57 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
58 René Rebe and Siegmund Gorr for reporting this.
60 2008-05-06, Version 4.4.0
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
67 for each data source.
68 * apache, nginx plugins: Added the possibility to disable host and/or
69 peer verification.
70 * ascent plugin: The new ascent plugin reads and parses the statistics
71 page of an Ascent server.

76 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
77 sensor values via IPMI, the intelligent platform management
78 interface.
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.
88 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
89 TeamSpeak2 server and collects statistics about the number of users
90 and number of channels.
91 * users plugin: Support for the statgrab library has been added.
92 * vmem plugin: The new vmem plugin collects very detailed statistics
93 about the virtual memory subsystem of Linux.
95 2008-08-30, Version 4.3.4
96 * Build system: Improved detection of and linking with the statgrab
97 library.
98 * collectd: Portability fixes, especially to determine endianess more
99 reliable.
100 * Various plugins: Fix format strings.
101 * disk plugin: A fix for giving disks under Linux 2.4 the right names
102 again has been applied.
103 * memcached plugin: Fix a too short timeout and a related file
104 descriptor leak.

114 * build system: Improved detection of several libraries, especially if
115 they are in non-standard paths.
116 * build system: Portability fixes: Automatically define "_REENTRANT"
117 if the libc expects it.
118 * collectd: Error and warning messages have been improved.
119 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
120 using them.
121 * apache plugin: Allocate new memory when reading a webpage instead of
122 using a buffer of static size.
123 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
124 the program.
125 * hddtemp plugin: Error and warning messages have been improved.
126 * sensors plugin: Fix sensor collection for some chip types.
128 2008-03-29, Version 4.3.2
129 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
130 `Persist' threshold options.
131 * collectd: Fix handling of missing values in the global value cache.

137 2008-03-05, Version 4.3.1
138 * exec plugin: Set supplementary group IDs.
139 * network plugin:
140 + Use `memcpy' when constructing/parsing a package to avoid
141 alignment problems on weird architectures, such as Sparc.
142 + Translate doubles to/from the x86 byte representation to ensure
143 cross-platform compatibility.
144 * ping plugin: Correct the handling of the `TTL' setting.
145 * swap plugin: Reapply a patch for Solaris.
146 * tcpconns plugin: Portability improvements.
148 2008-02-18, Version 4.3.0
149 * collectd: Notifications have been added to the daemon. Notifications
150 are status messages that may be associated with a data instance.
151 * collectd: Threshold checking has been added to the daemon. This
152 means that you can configure threshold values for each data
153 instance. If this threshold is exceeded a notification will be
154 created.
155 * collectd: The new `FQDNLookup' option tells the daemon to use the
156 full qualified domain name as the hostname, not just the host part
157 es returned by `gethostname(2)'.
158 * collectd: Support for more than one `TypesDB' file has been added.
159 This is useful when one such file is included in a package but one
160 wants to add custom type definitions.
161 * collectd: The `Include' config option has been expanded to handle
162 entire directories and shell wildcards.
163 * collectdmon: The new `collectdmon' binary detects when collectd
164 terminates and automatically restarts it again.
165 * csv plugin: The CSV plugin is now able to store counter values as a
166 rate, using the `StoreRates' configuration option.
167 * exec plugin: Handling of notifications has been added and the
168 ability to pass arguments to the executed programs has been added.
169 * hddtemp plugin: The new `TranslateDevicename' option lets you
170 disable the translation from device names to major-minor-numbers.
171 * logfile plugin: Handling of notifications has been added.
172 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
173 domain name lookups in this plugin.
174 * perl plugin: Many internal changes added support for handling multiple
175 threads making the plugin reasonably usable inside collectd. The API has
176 been extended to support notifications and export global variables to
177 Perl plugins; callbacks now have to be identified by name rather than a
178 pointer to a subroutine. The plugin is no longer experimental.
179 * uuid plugin: The new UUID plugin sets the hostname to an unique
180 identifier for this host. This is meant for setups where each client
181 may migrate to another physical host, possibly going through one or
182 more name changes in the process. Thanks to Richard Jones from
183 Red Hat's Emerging Technology group for this plugin.
184 * libvirt: The new libvirt plugin uses the `libvirt' library to query
185 CPU, disk and network statistics about guest systems on the same
186 physical server. Thanks to Richard Jones from Red Hat's Emerging
187 Technology group for this plugin.
189 2008-04-22, Version 4.2.7
190 * build system: Improved detection of several libraries, especially if
191 they are in non-standard paths.
192 * build system: Portability fixes: Automatically define "_REENTRANT"
193 if the libc expects it.
194 * collectd: Error and warning messages have been improved.
195 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
196 using them.
197 * apache plugin: Allocate new memory when reading a webpage instead of
198 using a buffer of static size.
199 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
200 the program.
201 * hddtemp plugin: Error and warning messages have been improved.
202 * sensors plugin: Fix sensor collection for some chip types.
204 2008-03-29, Version 4.2.6
205 * collectd: Improved error messages when parsing the configuration.
206 * sensors plugin: Fix temperature collection with libsensors4.
207 * unixsock plugin: Fix mixed input and output operation on streams.
208 * wireless plugin: Fix reading noise value.
210 2008-03-04, Version 4.2.5
211 * apache plugin: Improved initialization and error messages.
212 * exec plugin: Set supplementary group IDs.
213 * network plugin:
214 + Create separate threads for reading from the socket and parsing
215 and dispatching incoming packets. Versions prior to this may have
216 problems in high-load situations, where the socket receive buffers
217 overflows, resulting in gaps in the data.
218 + Use `memcpy' when constructing/parsing a package to avoid
219 alignment problems on weird architectures, such as Sparc.
220 + Translate doubles to/from the x86 byte representation to ensure
221 cross-platform compatibility.
222 * ping plugin: Correct the handling of the `TTL' setting.
223 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
224 * swap plugin: Reapply a patch for Solaris.
225 * tcpconns plugin: Portability improvements.
227 2008-01-21, Version 4.2.4
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 2007-12-28, Version 4.2.3
234 * sensors plugin: Updated the plugin to build and work with version 3
235 of the libsensors library.
237 2007-12-15, Version 4.2.2
238 * nginx plugin: Incorrect comparison of strings lead to a segfault
239 when using the plugin. Thanks to Saulius Grigaliunas for fixing
240 this.
241 * logfile plugin: The config option `Timestamp' was handled
242 incorrectly and basically always active. Thanks to Luke Heberling
243 for fixing this.
245 2007-11-08, Version 4.2.1
246 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
247 enabled on the host.
248 * snmp plugin: Fix a memory leak.
250 2007-10-27, Version 4.2.0
251 * collectd: The new config option `Include' lets you include other
252 configfiles and thus split up your config into smaller parts. This
253 may be especially interesting for the snmp plugin to keep the data
254 definitions separate from the host definitions.
255 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
256 (number of connections, octets and packets for each service and
257 destination). Thanks to Sebastian Harl for this plugin.
258 * memcached plugin: The new `memcached' plugin connects to a memcached
259 daemon process and collects statistics of this distributed caching
260 system. Thanks to Antony Dovgal for contributing this plugin.
261 * nginx plugin: The new `nginx' plugin reads the status page of an
262 nginx daemon and saves the handled connections and requests.
263 * perl plugin: Many changes, including the added `EnableDebugger'
264 config option which lets you debug your Perl plugins more easily.
265 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
266 be more thread-safe otherwise by locking calls to the library.
267 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
268 correct the values returned by SNMP-agents. If a <data> block is
269 defined as `table' the instance is now optional. The sequence number
270 is used as the type-instance in this case. The new `InstancePrefix'
271 option allows to add arbitrary prefixes to the type-instance.
272 * tcpconns plugin: The new `tcpconns' plugin collects the number of
273 certain TCP connections and what state they're in. This can be used
274 to see how many connections your FTP server has to handle or how
275 many outgoing connections your mailserver has open.
277 2008-01-11, Version 4.1.6
278 * unixsock plugin: A bug in the unixsock plugin caused it not to set
279 the permission on the socket as documented in the manpage. Thanks to
280 Evgeny Chukreev for fixing this issue.
281 * collectd: The documentation has been improved.
283 2007-12-27, Version 4.1.5
284 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
285 memory situations.
286 * sensors plugin: Updated the plugin to build and work with version 3
287 of the libsensors library.
289 2007-11-08, Version 4.1.4
290 * Build system: Improve detection of the rrd library, especially if
291 it's in a non-standard location.
292 * Build system: A bug when parsing the argument for
293 `--with-libnetsnmp' has been fixed.
294 * collectd: Implement `strerror_r' if the libc doesn't provide it.
295 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
296 a deadlock or delay when shutting down the daemon.
297 * snmp plugin: Fix a memory leak.
299 2007-10-24, Version 4.1.3
300 * collectd: A build issue under Solaris has been resolved by renaming
301 data types.
302 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
303 be more thread-safe otherwise by locking calls to the library.
305 2007-09-28, Version 4.1.2
306 * apcups plugin: Fix reporting of the `load percent' data.
307 * wireless plugin: Correct the handling of cards returning signal and
308 noise quality as percentage.
309 * perl plugin: Fix a possible buffer overflow in get_module_name().
310 * build system: Further improve the detection of libraries.
311 * netlink plugin: Build issues under some older versions of the Linux
312 includes (i. e. Debian Sarge) have been fixed.
313 * snmp plugin: Fix a potential segfault when a host times out. Add
314 support for the `timeticks' type.
316 2007-09-12, Version 4.1.1
317 * Build system: The detection of `libnetlink' has been improved.
318 * collectd: The documentation has been fixed in numerous places.
319 * exec plugin: Setting the group under which to run a program has been
320 fixed.
321 * collectd: The `sstrerror' function was improved to work correctly
322 with the broken GNU version of `strerror_r'.
323 * collectd: Write an error message to STDERR when loading of a plugin
324 fails.
325 * apcups plugin: Fix the `types' used to submit the values: They still
326 has an `apcups_' prefix which doesn't work anymore.
327 * rrdtool plugin: Create new RRD-files with the `begin' time set to
328 whatever the client thinks is `now'..
330 2007-09-01, Version 4.1.0
331 * Build system: The build system has been changed to automatically
332 disable all plugins, which are missing dependencies. The dependency
333 checking has been removed from the plugins themselves to remove
334 redundancy.
335 * Flexible interval: The interval of collected data is now sent along
336 with the data itself over the network, so that the interval-settings
337 of server and clients no longer needs to match.
338 * netlink plugin: The new `netlink' plugin connects to the Linux
339 kernel using a netlink socket and uses it to query information about
340 interfaces, qdiscs and classes.
341 * rrdtool plugin: The cache is now dumped to disk in an extra thread
342 to not block data collection.
343 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
344 network devices, such as switches, routers, thermometers, rack
345 monitoring servers, etc. The collectd-snmp(5) manpage documents this
346 plugin.
347 * unixsock plugin: Added the `LISTVAL' command.
348 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
349 of music played with xmms.
351 2007-09-28, Version 4.0.9
352 * apcups plugin: Fix reporting of the `load percent' data.
353 * wireless plugin: Correct the handling of cards returning signal and
354 noise quality as percentage.
355 * perl plugin: Fix a possible buffer overflow in get_module_name().
357 2007-09-12, Version 4.0.8
358 * collectd: The `sstrerror' function was improved to work correctly
359 with the broken GNU version of `strerror_r'.
360 * collectd: Write an error message to STDERR when loading of a plugin
361 fails.
362 * apcups plugin: Fix the `types' used to submit the values: They still
363 has an `apcups_' prefix which doesn't work anymore.
364 * rrdtool plugin: Create new RRD-files with the `begin' time set to
365 whatever the client thinks is `now'..
367 2007-08-26, Version 4.0.7
368 * documentation: Some typos have been fixed and some information has
369 been improved.
370 * build system: Many fixes for detecting libraries in unusual places,
371 such as on RedHat systems. The affected libraries are `libcurl',
372 `libmysql', and `libupsclient'.
373 * network plugin: Allow the `Port' option to be specified as a number
374 (i. e. without quotes).
375 * nut plugin: A fix allows linking the nut plugin against
376 libupsclient, version >= 2.2.0.
377 * processes plugin: Fix a potential segmentation fault.
379 2007-07-30, Version 4.0.6
380 * sensors plugin: Fix the ignorelist functionality: Only the `type
381 instance' was used to match against the list, but the documentation
382 told otherwise. This release fixes the code, so it complies with the
383 documentation.
384 * syslog plugin: Call `openlog' right when the plugin is loaded, so
385 configuration messages will end up in the logging facility.
386 * conrtib/fedora: The contributed specfile for Fedora has been
387 updated.
389 2007-07-05, Version 4.0.5
390 * Portability: More fixes for OpenBSD have been included.
392 2007-06-24, Version 4.0.4
393 * cpu plugin: Fixed the Solaris code.
394 * dns plugin: Fixed a build issue for OpenBSD.
395 * interface plugin: Fixed the Solaris code.
396 * load plugin: Fixed the alternative `/proc' Linux code.
397 * memory plugin: Fixed the Solaris code.
398 * oconfig: Don't require `-lfl' anymore.
400 2007-06-19, Version 4.0.3
401 * cpu plugin: Fix the Darwin / Mac OS X code.
402 * ping plugin: Use the return value of `getpid', not its address.
403 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
404 initialized correctly.
405 * configure: Added `--with-nan-emulation' to aid cross compilation.
407 2007-06-12, Version 4.0.2
408 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
409 they're given in numerically form.
411 2007-06-07, Version 4.0.1
412 * iptables plugin: A bug in the configuration routine has been fixed.
413 Setting a comment in the configfile will no longer cause a
414 segmentation fault.
416 2007-06-03, Version 4.0.0
417 * collectd: The plugin-infrastructure has been changed to allow for
418 more types of plugins, namely `write' and `log' plugins.
419 * collectd: The read-function has been changed to read many plugins in
420 parallel, using threads. Thus, plugins generally need to use
421 thread-safe functions from now on.
422 * collectd: The '-t' command line options allows to perform syntax tests
423 of the configuration file and exit immediately.
424 * csv plugin: The new `csv' plugin handles output to `comma separated
425 values'-files.
426 * rrdtool plugin: The new `rrdtool' plugin handles output to
427 RRD-files. Data can be cached to combine multiple updates into one
428 write to increase IO-performance.
429 * network plugin: The new `network' plugin handles IO via the network.
430 It implements a different, much more extensible protocol which can
431 combine many values in one packet, decreasing the number of UDP-
432 packets being sent. It can read from and send to the network and
433 with the appropriate configuration even forward packets to other
434 networks.
435 * unixsock plugin: The new `unixsock' plugin provides an interface to
436 communicate with the daemon while it is running. Right now the
437 commands `GETVAL' and `PUTVAL' are implemented, but more are to
438 come.
439 * perl plugin: The new `perl' plugin allows you to write extensions
440 for collectd in the scripting-language Perl.
441 * logfile plugin: The new `logfile' plugin writes logmessages to files
442 or STDOUT or STDERR.
443 * syslog plugin: The new `syslog' plugin sends logmessages to the
444 system's syslog daemon.
445 * entropy plugin: The new `entropy' plugin collects the amount of
446 entropy currently being available to the system.
447 * exec plugin: The new `exec' plugin forks child processes and reads
448 back values provided by the forked processes.
449 * iptables plugin: The new `iptables' plugin reads counters from
450 iptables rules. Thanks to Sjoerd van der Berg for contributing this
451 plugin.
452 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
453 to Peter Holik for contributing this plugin.
454 * nut plugin: The new `nut' plugin connects the upsd of the `network
455 ups tools' and reads information about the connected UPS.
456 * apache plugin: Support for lighttpd's `BusyServers' (aka.
457 connections) field was added by Florent Monbillard.
458 * collectd-nagios: The new `collectd-nagios' binary queries values
459 from collectd, parses them and exits according to Nagios-standards.
460 * manpages: The manpages have been improved a lot.
462 2007-09-28, Version 3.11.7
463 * wireless plugin: Correct the handling of cards returning signal and
464 noise quality as percentage.
466 2007-08-31, Version 3.11.6
467 * processes plugin: Fix a potential segmentation fault.
469 2007-05-29, Version 3.11.5
470 * configure: Added `AC_SYS_LARGEFILE' for LFS.
471 * ntpd plugin: Fix a potential buffer overflow.
472 * processes plugin: Fix a bug when run under Linux 2.4. All processes
473 were accounted as `zombies'.
475 2007-04-10, Version 3.11.4
476 * dns plugin: Change the order of includes to make the plugin compile
477 under FreeBSD.
479 2007-03-30, Version 3.11.3
480 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
481 of the unused `COLLECT_KSTAT'.
483 2007-02-11, Version 3.11.2
484 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
485 NULL-pointer may have been passed to `printf' which causes a
486 segfault with some libcs.
488 2007-02-10, Version 3.11.1
489 * df plugin: Some wrong defines have been fixed so the plugin works
490 under Solaris again.
491 * dns plugin: The usage of a struct has been fixed to work with
492 non-GNU libcs.
493 * processes plugin: Some missing defines have been added so the plugin
494 compiles cleanly under FreeBSD and presumably other UNIXes.
496 2006-12-22, Version 3.11.0
497 * collectd: The new command line option `-P' makes it easier for
498 distributors to change the location of PID-files.
499 * collectd: The daemon shuts down faster now which makes it easier to
500 write init.d-scripts for it.
501 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
502 caused problems every now and then.
503 * df plugin: New config options allow to ignore certain mountpoints,
504 filesystem types or devices.
505 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
506 and interprets it. It collects traffic as well as qtype, opcode and
507 rcode counts.
508 * email plugin: Sebastian Harl has contributed this plugin which
509 counts received mails in categories (e. g. ham, spam, virus), spam
510 score (as given by SpamAssassin) and check types.
511 * mbmon plugin: Flavio Stanchina has contributed this plugin which
512 uses `mbmon' to gather information from sensors on the motherboard.
513 * processes plugin: Collect detailed statistics for configured
514 processes, that's process and thread count, CPU usage, resident
515 segment size and pagefaults.
516 * multimeter plugin: Peter Holik contributed a new plugin which
517 queries multimeters.
518 * sensors plugin: Lubos Stanek has put much effort into improving this
519 plugin, including `extended naming', collection of voltage values
520 and the possibility to ignore certain values.
522 2006-12-21, Version 3.10.4
523 * Max Kellermann has identified a bug in the server routine: When
524 opening a socket fails the daemon will (re)try opening the socket in
525 an endless loop, ultimately leading to a `EMFILE' error.
527 2006-11-04, Version 3.10.3
528 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
529 ntpd's reply was sent in more than one packet, the buffer size was
530 calculated incorrectly, resulting in the reading of uninitialized or
531 freed memory.
533 2006-11-01, Version 3.10.2
534 * The sample config file has been improved.
535 * Errors in the manpages have been corrected.
536 * The ping-plugin now adds hosts during initialization, not during
537 startup. This speeds up startup when no network connectivity is
538 available. Also, the hosts are being added later when the network is
539 available.
540 * Improved BSD-support for the df-plugin.
541 * Fixed syntax errors in the swap-plugin for Mac OS X.
542 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
543 plugin.
544 * Don't disable the mysql-plugin if connecting to the database fails
545 during initialization. Instead, try again in increasing intervals.
547 2006-07-19, Version 3.10.1
548 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
549 the apcups cannot be reached, unconnected sockets will pile up and
550 eventually lead to `Too many open files' errors.
552 2006-07-09, Version 3.10.0
553 * The `disk' plugin has been ported to Darwin.
554 * The `battery' plugin should work on many Apple computers now.
555 * The `traffic' plugin can now ignore certain interfaces. Also,
556 statistics for sent/received packets and errors have been added.
557 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
558 to Anthony Gialluca for contributing this plugin and providing me
559 with a test environment :)
560 * A plugin for monitoring an NTP instance and the local clock drift
561 has been added.
563 2006-06-25, Version 3.9.4
564 * The Solaris code in the `swap' plugin has been changed to reflect
565 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
566 working this out.
567 * The debugging system has been fixed to work with the Sun libc.
568 * When built without librrd the variable `operating_mode' could be
569 uninitialized. Thanks to David Elliot for reporting the bug.
571 2006-06-01, Version 3.9.3
572 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
573 operating systems also profit from the changes, but I wasn't able to
574 check that.
575 * Changed the build system to find the netinet-includes under FreeBSD
576 and therefore successfully build the `liboping' library there.
578 2006-05-09, Version 3.9.2
579 * Applied a patch to the `liboping' library. Due to a bug in the
580 sequence checking the `ping' plugin stopped working after
581 approximately 7.6 days.
583 2006-05-09, Version 3.8.5
584 * Applied a patch to the `liboping' library. Due to a bug in the
585 sequence checking the `ping' plugin stopped working after
586 approximately 7.6 days.
588 2006-04-21, Version 3.9.1
589 * Build issues with Solaris and possible other architectures have been
590 resolved.
591 * Problems when building the `apache'-plugin without `libcurl' have
592 been resolved.
593 * A bug in the `ping' plugin has been fixed. Sorry folks.
595 2006-04-02, Version 3.9.0
596 * A plugin to monitor the Apache webserver has been added.
597 <http://httpd.apache.org/>
598 * A plugin to collect statistics about virtual servers using VServer.
599 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
600 this plugin :)
601 * A plugin for wireless LAN cards has been added. It monitors signal
602 strength, link quality and noise ratio..
603 * A plugin for Apple hardware sensors has been added.
604 * An option to compile collectd with different `step' and `heartbeat'
605 settings has been added. The size of RRAs is no longer static but
606 calculated based on the settings for `step' and `width'.
607 * The `ping' plugin can now be configured to use a certain TTL.
608 * A plugin to monitor the hardware sensors of Apple computers has been
609 added.
610 * The plugins `cpu', `memory', `processes' and `traffic' have been
611 ported to Mach/Darwin (Mac OS X).
612 * The `log mode' has been contributed by Christophe Kalt. It writes
613 the data into text files rather than RRD files.
615 2006-04-09, Version 3.8.4
616 * Applied patch by Vincent Stehlé which improves the disk-name
617 resolution in the `hddtemp' plugin for Linux systems.
619 2006-04-02, Version 3.8.3
620 * Applied a patch by James Byers: The MySQL plugin was not working
621 with MySQL 5.0.2 or later.
623 2006-03-14, Version 3.8.2
624 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
625 the GNU libc, because it points to `/etc/fstab' rather than
626 `/etc/mtab'.
628 2006-03-13, Version 3.8.1
629 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
630 * Fixes in the debian `postinst' and `init.d' scripts.
632 2006-03-09, Version 3.8.0
633 * The `ping' plugin no longer uses `libping' but a self written
634 library named `liboping'. With this library it's possible to ping
635 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
637 2006-02-18, Version 3.7.2
638 * A simple bug in the `battery' plugin has been fixed. It should now
639 work with ACPI based batteries as well. Thanks to Sebastian for
640 fixing this.
641 * Fixing a bug that prevented collectd to be built without librrd.
642 Thanks to Werner Heuser for reporting it.
644 2006-02-04, Version 3.7.1
645 * The new network code has been improved to build with older versions
646 of glibc.
647 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
648 to Tommie Gannert for this patch.
650 2006-01-30, Version 3.7.0
651 * The `battery' plugin has been added. It collects information about
652 laptop batteries..
653 * The MySQL plugin has been improved: It now writes two more RRD
654 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
655 * The `cpufreq' plugin now reads another file since the file it did
656 read so far causes much overhead in the kernel. Also, you need root
657 to read the old file, but not to read the new one.
658 * The `hddtemp' plugin can now be configured to connect to another
659 address and/or port than localhost.
660 * The `df' plugin now prefers `statvfs' over `statfs'.
661 * The network code has been rewritten. collectd now supports unicast
662 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
663 be set in the configfile.
665 2006-01-24, Version 3.6.2
666 * Due to a bug in the configfile handling collectd wouldn't start in
667 client mode. This released fixes this.
669 2006-01-20, Version 3.6.1
670 * Due to a bug in `configure.in' all modules and the binary were
671 linked against `libmysqlclient'. This issue is solved by this
672 release.
674 2006-01-17, Version 3.6.0
675 * A config file has been added. This allows for loading only specific
676 plugins.
677 * A `df' plugin has been added.
678 * A `mysql' plugin has been added.
679 * The `ping' plugin doesn't entirely give up hope when a socket error
680 occurred, but will back of and increase the intervals between tries.
682 2006-01-21, Version 3.5.2
683 * Fixed yet another bug in the signal handling.. Stupid typo..
684 * Improved the ping plugin to not give up on socket errors (backport
685 from 3.6.0).
687 2005-12-18, Version 3.5.1
688 * The PID-file is now deleted correctly when shutting down the daemon.
689 * SIGINT and SIGTERM are now handled correctly.
691 2005-12-16, Version 3.5.0 (Revision 326)
692 * A bug in the `load' module under Solaris has been fixed.
693 * The `users' module has been contributed by Sebastian Harl. It counts
694 currently logged in users.
695 * The CPU module now works under FreeBSD without the use of
696 `libstatgrab', however SMP support is missing.
697 * The default directories for the RRD files and the PID file now
698 depend on the compile time setting of `localstatedir'.
700 2005-11-15, Version 3.4.0 (Revision 236)
701 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
702 from gentoo's bugzilla for writing the patch.
703 * The build dependency for librrd has been removed. Binaries built
704 without librrd are client-only and will multicast their value as
705 with the `-c' argument.
706 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
707 * The newly introduced `-f' switch prevents daemon initialization
708 (forking, closing standard filehandles, etc.) Thanks to Alvaro
709 Barcellos for this patch.
711 2005-11-04, Version 3.3.0 (Revision 216)
712 * New modules have been added:
713 - `serial', for monitoring traffic on the serial interfaces
714 - `nfs', for graphing NFS procedure calls
715 - `tape', traffic from/to tape devices
716 * The memory.rrd now accepts more than 4Gig of memory.
718 2005-10-26, Version 3.2.0 (Revision 200)
719 * Support for graphing the processes has been added (thanks to Lyonel
720 Vincent)
721 * If reading from hddtemp fails collectd will increase the time
722 between polls up to one day.
723 * The init.d files have been improved.
724 * Problems with the spec file have been fixed.
726 2005-10-16, Version 3.1.0 (Revision 194)
727 * Added the `setsid' syscall to the startup code.
728 * Support for hddtemp has been added (thanks to Vincent Stehlé)
730 2005-09-30, Version 3.0.0 (Revision 184)
731 * The ability to send/receive data to/from the network (think
732 multicast) has been added.
733 * Modules have been split up into shared libraries can be loaded at
734 runtime. The biggest advantage is that the core program doesn't need
735 to be linked against an external library.
736 * A patch by George Kargiotakis has been applied: It fixes the sensors
737 behaviour then more than one sensor is being queried.
739 2005-09-16, Version 2.1.0 (Revision 172)
740 * A module for swap statistics has been added.
742 2005-09-09, Version 2.0.0 (Revision 135)
743 * Filenames can no longer be configured at program startup. The only
744 options as of this version are the directory and ping hosts.
745 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
746 Soft-IRQ statistics are added to `System'.
747 * Diskstats now collect read and write bytes, not sectors.
748 * Ping statistics can now be collected for more than one host. There
749 is no default any more: If no host is given no host will be pinged.
750 * A self-written patch for libping has been applied so it builds
751 cleanly.
753 2005-09-01, Version 1.8.1 (Revision 123)
754 * Much improved configure-script: libraries and features may now be
755 disabled.
756 * More detailed warnings/error messages when RRD update fails.
758 2005-08-29, Version 1.8.0:
759 * Support for collecting disk statistics under Solaris.
761 2005-08-25, Version 1.7.0:
762 * Support for libstatgrab[1] for load, memory usage and network
763 traffic. CPU- and disk-usage are not (yet) supported, since
764 libstatgrab returns insufficient information. I will contact the
765 authors.
766 * Improved the CPU-initialization code for Solaris. Apparently CPUs
767 aren't necessarily counted linear which is now handled correctly.
768 [1]: http://www.i-scream.org/libstatgrab/
770 2005-08-21, Version 1.6.0:
771 * Basic support for Solaris: System load and cpu-usage can be
772 collected under Solaris, too. Other stats will follow later.
773 * Many fixes in the autoconf-script
774 * Collection/Museum scripts have been added under contrib/museum
775 * collectd may now be started in unprivileged mode, though ping
776 statistics will not work.
778 2005-07-17, Version 1.5.1:
779 * Diskstats-RRDs now use major/minor for naming. Some systems have
780 weird strings as disk-names..
782 2005-07-17, Version 1.5:
783 * A new module, diskstats, has been added. It collects information
784 about the disks and partitions.
786 2005-07-11, Version 1.4.2:
787 * The meminfo module has been changed to work with more platforms
788 and/or kernel versions.
790 2005-07-10, Version 1.4.1: Correct traffic stats
791 * The traffic rrd-file is now created with DS-type `COUNTER' which I
792 forgot to correct when I changed that module.
794 2005-07-09, Version 1.4: More traffic stats
795 * Traffic is now collected for all interfaces that can be found
796 * Temperature-statistics are read from lm-sensors if available
798 2005-07-08, Version 1.3: CPU stats
799 * Collecting CPU statistics now
801 2004-07-12, Version 1.2: Using syslog
802 * collectd is now using the syslog facility to report errors, warnings
803 and the like..
804 * The default directory is now /var/db/collectd
806 2004-07-10, Version 1.1: Minor changes
807 * Nothing really useful to say ;)
809 2004-07-09, Version 1.0: Initial Version
810 * The following modules are provided:
811 * Load average
812 * Ping time
813 * Traffic
814 * Memory info
