6 of disks.
7 * dns plugin: Fix compilation errors with BIND versions 19991001
8 through 19991005.
9 * network plugin: Bugfix in the init routine: The init function
10 cleared a buffer regardless of its contents. This could lead to lost
11 values under Solaris.
12 * nginx plugin: Remove usage of the thread-unsafe `strtok' function.
13 * vserver plugin: Remove usage of the thread-unsafe `readdir'
14 function.
15 * wireless plugin: Work around incorrect noise and power values
16 returned by some broken drivers.
18 2008-06-03, Version 4.4.1
19 * collectd: Fix the `DataSource' option within `Type' blocks. Thanks
20 to kyrone for reporting this.
21 * collectd: Fixed min/max output in notifications generated by
22 threshold checking.
23 * collectd-nagios: Fix the protocol used to communicate with the
24 daemon.
25 * perl plugin: Fail noisily, but don't shutdown the daemon, if
26 initialization has errors. An issue with Perl 5.10 has been fixed.
27 * teamspeak2 plugin: Fixed an out of bounce array access. Thanks to
28 René Rebe and Siegmund Gorr for reporting this.
30 2008-05-06, Version 4.4.0
31 * collectd: Internal code cleanups.
32 * collectd: Added support for a `Flush' command in the unixsock and
33 exec plugins. This command can be used to force a plugin (or all) to
34 flush its values to disk.
35 * collectd: Thresholds can now be configured to apply to one data
36 source only, making it possible to configure different thresholds
37 for each data source.
38 * apache, nginx plugins: Added the possibility to disable host and/or
39 peer verification.
40 * ascent plugin: The new ascent plugin reads and parses the statistics
41 page of an Ascent server.

43 * disk plugin: The possibility to ignore certain disks or collect only
44 specific disks has been added.
45 * disk plugin: Support for the statgrab library has been added.
46 * ipmi plugin: The new ipmi plugin uses the OpenIPMI library to read
47 sensor values via IPMI, the intelligent platform management
48 interface.
49 * iptables plugin: The iptc library that is used by the iptables
50 plugin has been added to the distribution, because it is not
51 provided by all distributions and removed from at least one.
52 * powerdns plugin: The new powerdns plugin reads statistics from an
53 authoritative or a recursing PowerDNS name server.
54 * rrdtool plugin: The size of the files generated with the default
55 configuration has been decreased.
56 * tail plugin: The new tail plugin can be used to gather statistics by
57 continuously reading from log files.
58 * teamspeak2 plugin: The new teamspeak2 plugin connects to a
59 TeamSpeak2 server and collects statistics about the number of users
60 and number of channels.
61 * users plugin: Support for the statgrab library has been added.
62 * vmem plugin: The new vmem plugin collects very detailed statistics
63 about the virtual memory subsystem of Linux.
65 2008-08-30, Version 4.3.4
66 * Build system: Improved detection of and linking with the statgrab
67 library.
68 * collectd: Portability fixes, especially to determine endianess more
69 reliable.
70 * Various plugins: Fix format strings.
71 * disk plugin: A fix for giving disks under Linux 2.4 the right names
72 again has been applied.
73 * memcached plugin: Fix a too short timeout and a related file
74 descriptor leak.
75 * memory plugin: A typo in the libstatgrab code has been fixed.
76 * network plugin: A fix in the initialization function solves problems
77 under Solaris.
78 * nginx plugin: A thread-unsafe function has been replaced.
79 * vserver plugin: A thread-unsafe function has been replaced.

81 added.
83 2008-04-22, Version 4.3.3
84 * build system: Improved detection of several libraries, especially if
85 they are in non-standard paths.
86 * build system: Portability fixes: Automatically define "_REENTRANT"
87 if the libc expects it.
88 * collectd: Error and warning messages have been improved.
89 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
90 using them.
91 * apache plugin: Allocate new memory when reading a webpage instead of
92 using a buffer of static size.
93 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
94 the program.
95 * hddtemp plugin: Error and warning messages have been improved.
96 * sensors plugin: Fix sensor collection for some chip types.
98 2008-03-29, Version 4.3.2
99 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
100 `Persist' threshold options.
101 * collectd: Fix handling of missing values in the global value cache.
102 * collectd: Improved error messages when parsing the configuration.
103 * sensors plugin: Fix temperature collection with libsensors4.
104 * unixsock plugin: Fix mixed input and output operation on streams.
105 * wireless plugin: Fix reading noise value.
107 2008-03-05, Version 4.3.1
108 * exec plugin: Set supplementary group IDs.
109 * network plugin:
110 + Use `memcpy' when constructing/parsing a package to avoid
111 alignment problems on weird architectures, such as Sparc.
112 + Translate doubles to/from the x86 byte representation to ensure
113 cross-platform compatibility.
114 * ping plugin: Correct the handling of the `TTL' setting.
115 * swap plugin: Reapply a patch for Solaris.
116 * tcpconns plugin: Portability improvements.
118 2008-02-18, Version 4.3.0
119 * collectd: Notifications have been added to the daemon. Notifications
120 are status messages that may be associated with a data instance.
121 * collectd: Threshold checking has been added to the daemon. This
122 means that you can configure threshold values for each data
123 instance. If this threshold is exceeded a notification will be
124 created.
125 * collectd: The new `FQDNLookup' option tells the daemon to use the
126 full qualified domain name as the hostname, not just the host part
127 es returned by `gethostname(2)'.
128 * collectd: Support for more than one `TypesDB' file has been added.
129 This is useful when one such file is included in a package but one
130 wants to add custom type definitions.
131 * collectd: The `Include' config option has been expanded to handle
132 entire directories and shell wildcards.
133 * collectdmon: The new `collectdmon' binary detects when collectd
134 terminates and automatically restarts it again.
135 * csv plugin: The CSV plugin is now able to store counter values as a
136 rate, using the `StoreRates' configuration option.
137 * exec plugin: Handling of notifications has been added and the
138 ability to pass arguments to the executed programs has been added.
139 * hddtemp plugin: The new `TranslateDevicename' option lets you
140 disable the translation from device names to major-minor-numbers.
141 * logfile plugin: Handling of notifications has been added.
142 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
143 domain name lookups in this plugin.
144 * perl plugin: Many internal changes added support for handling multiple
145 threads making the plugin reasonably usable inside collectd. The API has
146 been extended to support notifications and export global variables to
147 Perl plugins; callbacks now have to be identified by name rather than a
148 pointer to a subroutine. The plugin is no longer experimental.
149 * uuid plugin: The new UUID plugin sets the hostname to an unique
150 identifier for this host. This is meant for setups where each client
151 may migrate to another physical host, possibly going through one or
152 more name changes in the process. Thanks to Richard Jones from
153 Red Hat's Emerging Technology group for this plugin.
154 * libvirt: The new libvirt plugin uses the `libvirt' library to query
155 CPU, disk and network statistics about guest systems on the same
156 physical server. Thanks to Richard Jones from Red Hat's Emerging
157 Technology group for this plugin.
159 2008-04-22, Version 4.2.7
160 * build system: Improved detection of several libraries, especially if
161 they are in non-standard paths.
162 * build system: Portability fixes: Automatically define "_REENTRANT"
163 if the libc expects it.
164 * collectd: Error and warning messages have been improved.
165 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
166 using them.
167 * apache plugin: Allocate new memory when reading a webpage instead of
168 using a buffer of static size.
169 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
170 the program.
171 * hddtemp plugin: Error and warning messages have been improved.
172 * sensors plugin: Fix sensor collection for some chip types.
174 2008-03-29, Version 4.2.6
175 * collectd: Improved error messages when parsing the configuration.
176 * sensors plugin: Fix temperature collection with libsensors4.
177 * unixsock plugin: Fix mixed input and output operation on streams.
178 * wireless plugin: Fix reading noise value.
180 2008-03-04, Version 4.2.5
181 * apache plugin: Improved initialization and error messages.
182 * exec plugin: Set supplementary group IDs.
183 * network plugin:
184 + Create separate threads for reading from the socket and parsing
185 and dispatching incoming packets. Versions prior to this may have
186 problems in high-load situations, where the socket receive buffers
187 overflows, resulting in gaps in the data.
188 + Use `memcpy' when constructing/parsing a package to avoid
189 alignment problems on weird architectures, such as Sparc.
190 + Translate doubles to/from the x86 byte representation to ensure
191 cross-platform compatibility.
192 * ping plugin: Correct the handling of the `TTL' setting.
193 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
194 * swap plugin: Reapply a patch for Solaris.
195 * tcpconns plugin: Portability improvements.
197 2008-01-21, Version 4.2.4
198 * unixsock plugin: A bug in the unixsock plugin caused it not to set
199 the permission on the socket as documented in the manpage. Thanks to
200 Evgeny Chukreev for fixing this issue.
201 * collectd: The documentation has been improved.
203 2007-12-28, Version 4.2.3
204 * sensors plugin: Updated the plugin to build and work with version 3
205 of the libsensors library.
207 2007-12-15, Version 4.2.2
208 * nginx plugin: Incorrect comparison of strings lead to a segfault
209 when using the plugin. Thanks to Saulius Grigaliunas for fixing
210 this.
211 * logfile plugin: The config option `Timestamp' was handled
212 incorrectly and basically always active. Thanks to Luke Heberling
213 for fixing this.
215 2007-11-08, Version 4.2.1
216 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
217 enabled on the host.
218 * snmp plugin: Fix a memory leak.
220 2007-10-27, Version 4.2.0
221 * collectd: The new config option `Include' lets you include other
222 configfiles and thus split up your config into smaller parts. This
223 may be especially interesting for the snmp plugin to keep the data
224 definitions separate from the host definitions.
225 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
226 (number of connections, octets and packets for each service and
227 destination). Thanks to Sebastian Harl for this plugin.
228 * memcached plugin: The new `memcached' plugin connects to a memcached
229 daemon process and collects statistics of this distributed caching
230 system. Thanks to Antony Dovgal for contributing this plugin.
231 * nginx plugin: The new `nginx' plugin reads the status page of an
232 nginx daemon and saves the handled connections and requests.
233 * perl plugin: Many changes, including the added `EnableDebugger'
234 config option which lets you debug your Perl plugins more easily.
235 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
236 be more thread-safe otherwise by locking calls to the library.
237 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
238 correct the values returned by SNMP-agents. If a <data> block is
239 defined as `table' the instance is now optional. The sequence number
240 is used as the type-instance in this case. The new `InstancePrefix'
241 option allows to add arbitrary prefixes to the type-instance.
242 * tcpconns plugin: The new `tcpconns' plugin collects the number of
243 certain TCP connections and what state they're in. This can be used
244 to see how many connections your FTP server has to handle or how
245 many outgoing connections your mailserver has open.
247 2008-01-11, Version 4.1.6
248 * unixsock plugin: A bug in the unixsock plugin caused it not to set
249 the permission on the socket as documented in the manpage. Thanks to
250 Evgeny Chukreev for fixing this issue.
251 * collectd: The documentation has been improved.
253 2007-12-27, Version 4.1.5
254 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
255 memory situations.
256 * sensors plugin: Updated the plugin to build and work with version 3
257 of the libsensors library.
259 2007-11-08, Version 4.1.4
260 * Build system: Improve detection of the rrd library, especially if
261 it's in a non-standard location.
262 * Build system: A bug when parsing the argument for
263 `--with-libnetsnmp' has been fixed.
264 * collectd: Implement `strerror_r' if the libc doesn't provide it.
265 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
266 a deadlock or delay when shutting down the daemon.
267 * snmp plugin: Fix a memory leak.
269 2007-10-24, Version 4.1.3
270 * collectd: A build issue under Solaris has been resolved by renaming
271 data types.
272 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
273 be more thread-safe otherwise by locking calls to the library.
275 2007-09-28, Version 4.1.2
276 * apcups plugin: Fix reporting of the `load percent' data.
277 * wireless plugin: Correct the handling of cards returning signal and
278 noise quality as percentage.
279 * perl plugin: Fix a possible buffer overflow in get_module_name().
280 * build system: Further improve the detection of libraries.
281 * netlink plugin: Build issues under some older versions of the Linux
282 includes (i. e. Debian Sarge) have been fixed.
283 * snmp plugin: Fix a potential segfault when a host times out. Add
284 support for the `timeticks' type.
286 2007-09-12, Version 4.1.1
287 * Build system: The detection of `libnetlink' has been improved.
288 * collectd: The documentation has been fixed in numerous places.
289 * exec plugin: Setting the group under which to run a program has been
290 fixed.
291 * collectd: The `sstrerror' function was improved to work correctly
292 with the broken GNU version of `strerror_r'.
293 * collectd: Write an error message to STDERR when loading of a plugin
294 fails.
295 * apcups plugin: Fix the `types' used to submit the values: They still
296 has an `apcups_' prefix which doesn't work anymore.
297 * rrdtool plugin: Create new RRD-files with the `begin' time set to
298 whatever the client thinks is `now'..
300 2007-09-01, Version 4.1.0
301 * Build system: The build system has been changed to automatically
302 disable all plugins, which are missing dependencies. The dependency
303 checking has been removed from the plugins themselves to remove
304 redundancy.
305 * Flexible interval: The interval of collected data is now sent along
306 with the data itself over the network, so that the interval-settings
307 of server and clients no longer needs to match.
308 * netlink plugin: The new `netlink' plugin connects to the Linux
309 kernel using a netlink socket and uses it to query information about
310 interfaces, qdiscs and classes.
311 * rrdtool plugin: The cache is now dumped to disk in an extra thread
312 to not block data collection.
313 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
314 network devices, such as switches, routers, thermometers, rack
315 monitoring servers, etc. The collectd-snmp(5) manpage documents this
316 plugin.
317 * unixsock plugin: Added the `LISTVAL' command.
318 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
319 of music played with xmms.
321 2007-09-28, Version 4.0.9
322 * apcups plugin: Fix reporting of the `load percent' data.
323 * wireless plugin: Correct the handling of cards returning signal and
324 noise quality as percentage.
325 * perl plugin: Fix a possible buffer overflow in get_module_name().
327 2007-09-12, Version 4.0.8
328 * collectd: The `sstrerror' function was improved to work correctly
329 with the broken GNU version of `strerror_r'.
330 * collectd: Write an error message to STDERR when loading of a plugin
331 fails.
332 * apcups plugin: Fix the `types' used to submit the values: They still
333 has an `apcups_' prefix which doesn't work anymore.
334 * rrdtool plugin: Create new RRD-files with the `begin' time set to
335 whatever the client thinks is `now'..
337 2007-08-26, Version 4.0.7
338 * documentation: Some typos have been fixed and some information has
339 been improved.
340 * build system: Many fixes for detecting libraries in unusual places,
341 such as on RedHat systems. The affected libraries are `libcurl',
342 `libmysql', and `libupsclient'.
343 * network plugin: Allow the `Port' option to be specified as a number
344 (i. e. without quotes).
345 * nut plugin: A fix allows linking the nut plugin against
346 libupsclient, version >= 2.2.0.
347 * processes plugin: Fix a potential segmentation fault.
349 2007-07-30, Version 4.0.6
350 * sensors plugin: Fix the ignorelist functionality: Only the `type
351 instance' was used to match against the list, but the documentation
352 told otherwise. This release fixes the code, so it complies with the
353 documentation.
354 * syslog plugin: Call `openlog' right when the plugin is loaded, so
355 configuration messages will end up in the logging facility.
356 * conrtib/fedora: The contributed specfile for Fedora has been
357 updated.
359 2007-07-05, Version 4.0.5
360 * Portability: More fixes for OpenBSD have been included.
362 2007-06-24, Version 4.0.4
363 * cpu plugin: Fixed the Solaris code.
364 * dns plugin: Fixed a build issue for OpenBSD.
365 * interface plugin: Fixed the Solaris code.
366 * load plugin: Fixed the alternative `/proc' Linux code.
367 * memory plugin: Fixed the Solaris code.
368 * oconfig: Don't require `-lfl' anymore.
370 2007-06-19, Version 4.0.3
371 * cpu plugin: Fix the Darwin / Mac OS X code.
372 * ping plugin: Use the return value of `getpid', not its address.
373 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
374 initialized correctly.
375 * configure: Added `--with-nan-emulation' to aid cross compilation.
377 2007-06-12, Version 4.0.2
378 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
379 they're given in numerically form.
381 2007-06-07, Version 4.0.1
382 * iptables plugin: A bug in the configuration routine has been fixed.
383 Setting a comment in the configfile will no longer cause a
384 segmentation fault.
386 2007-06-03, Version 4.0.0
387 * collectd: The plugin-infrastructure has been changed to allow for
388 more types of plugins, namely `write' and `log' plugins.
389 * collectd: The read-function has been changed to read many plugins in
390 parallel, using threads. Thus, plugins generally need to use
391 thread-safe functions from now on.
392 * collectd: The '-t' command line options allows to perform syntax tests
393 of the configuration file and exit immediately.
394 * csv plugin: The new `csv' plugin handles output to `comma separated
395 values'-files.
396 * rrdtool plugin: The new `rrdtool' plugin handles output to
397 RRD-files. Data can be cached to combine multiple updates into one
398 write to increase IO-performance.
399 * network plugin: The new `network' plugin handles IO via the network.
400 It implements a different, much more extensible protocol which can
401 combine many values in one packet, decreasing the number of UDP-
402 packets being sent. It can read from and send to the network and
403 with the appropriate configuration even forward packets to other
404 networks.
405 * unixsock plugin: The new `unixsock' plugin provides an interface to
406 communicate with the daemon while it is running. Right now the
407 commands `GETVAL' and `PUTVAL' are implemented, but more are to
408 come.
409 * perl plugin: The new `perl' plugin allows you to write extensions
410 for collectd in the scripting-language Perl.
411 * logfile plugin: The new `logfile' plugin writes logmessages to files
412 or STDOUT or STDERR.
413 * syslog plugin: The new `syslog' plugin sends logmessages to the
414 system's syslog daemon.
415 * entropy plugin: The new `entropy' plugin collects the amount of
416 entropy currently being available to the system.
417 * exec plugin: The new `exec' plugin forks child processes and reads
418 back values provided by the forked processes.
419 * iptables plugin: The new `iptables' plugin reads counters from
420 iptables rules. Thanks to Sjoerd van der Berg for contributing this
421 plugin.
422 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
423 to Peter Holik for contributing this plugin.
424 * nut plugin: The new `nut' plugin connects the upsd of the `network
425 ups tools' and reads information about the connected UPS.
426 * apache plugin: Support for lighttpd's `BusyServers' (aka.
427 connections) field was added by Florent Monbillard.
428 * collectd-nagios: The new `collectd-nagios' binary queries values
429 from collectd, parses them and exits according to Nagios-standards.
430 * manpages: The manpages have been improved a lot.
432 2007-09-28, Version 3.11.7
433 * wireless plugin: Correct the handling of cards returning signal and
434 noise quality as percentage.
436 2007-08-31, Version 3.11.6
437 * processes plugin: Fix a potential segmentation fault.
439 2007-05-29, Version 3.11.5
440 * configure: Added `AC_SYS_LARGEFILE' for LFS.
441 * ntpd plugin: Fix a potential buffer overflow.
442 * processes plugin: Fix a bug when run under Linux 2.4. All processes
443 were accounted as `zombies'.
445 2007-04-10, Version 3.11.4
446 * dns plugin: Change the order of includes to make the plugin compile
447 under FreeBSD.
449 2007-03-30, Version 3.11.3
450 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
451 of the unused `COLLECT_KSTAT'.
453 2007-02-11, Version 3.11.2
454 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
455 NULL-pointer may have been passed to `printf' which causes a
456 segfault with some libcs.
458 2007-02-10, Version 3.11.1
459 * df plugin: Some wrong defines have been fixed so the plugin works
460 under Solaris again.
461 * dns plugin: The usage of a struct has been fixed to work with
462 non-GNU libcs.
463 * processes plugin: Some missing defines have been added so the plugin
464 compiles cleanly under FreeBSD and presumably other UNIXes.
466 2006-12-22, Version 3.11.0
467 * collectd: The new command line option `-P' makes it easier for
468 distributors to change the location of PID-files.
469 * collectd: The daemon shuts down faster now which makes it easier to
470 write init.d-scripts for it.
471 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
472 caused problems every now and then.
473 * df plugin: New config options allow to ignore certain mountpoints,
474 filesystem types or devices.
475 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
476 and interprets it. It collects traffic as well as qtype, opcode and
477 rcode counts.
478 * email plugin: Sebastian Harl has contributed this plugin which
479 counts received mails in categories (e. g. ham, spam, virus), spam
480 score (as given by SpamAssassin) and check types.
481 * mbmon plugin: Flavio Stanchina has contributed this plugin which
482 uses `mbmon' to gather information from sensors on the motherboard.
483 * processes plugin: Collect detailed statistics for configured
484 processes, that's process and thread count, CPU usage, resident
485 segment size and pagefaults.
486 * multimeter plugin: Peter Holik contributed a new plugin which

488 * sensors plugin: Lubos Stanek has put much effort into improving this
489 plugin, including `extended naming', collection of voltage values
490 and the possibility to ignore certain values.
492 2006-12-21, Version 3.10.4
493 * Max Kellermann has identified a bug in the server routine: When
494 opening a socket fails the daemon will (re)try opening the socket in
495 an endless loop, ultimately leading to a `EMFILE' error.
497 2006-11-04, Version 3.10.3
498 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
499 ntpd's reply was sent in more than one packet, the buffer size was
500 calculated incorrectly, resulting in the reading of uninitialized or
501 freed memory.
503 2006-11-01, Version 3.10.2
504 * The sample config file has been improved.
505 * Errors in the manpages have been corrected.
506 * The ping-plugin now adds hosts during initialization, not during
507 startup. This speeds up startup when no network connectivity is
508 available. Also, the hosts are being added later when the network is
509 available.
510 * Improved BSD-support for the df-plugin.
511 * Fixed syntax errors in the swap-plugin for Mac OS X.
512 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
513 plugin.
514 * Don't disable the mysql-plugin if connecting to the database fails
515 during initialization. Instead, try again in increasing intervals.
517 2006-07-19, Version 3.10.1
518 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
519 the apcups cannot be reached, unconnected sockets will pile up and
520 eventually lead to `Too many open files' errors.
522 2006-07-09, Version 3.10.0
523 * The `disk' plugin has been ported to Darwin.
524 * The `battery' plugin should work on many Apple computers now.
525 * The `traffic' plugin can now ignore certain interfaces. Also,
526 statistics for sent/received packets and errors have been added.
527 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
528 to Anthony Gialluca for contributing this plugin and providing me
529 with a test environment :)
530 * A plugin for monitoring an NTP instance and the local clock drift
531 has been added.
533 2006-06-25, Version 3.9.4
534 * The Solaris code in the `swap' plugin has been changed to reflect
535 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
536 working this out.
537 * The debugging system has been fixed to work with the Sun libc.
538 * When built without librrd the variable `operating_mode' could be
539 uninitialized. Thanks to David Elliot for reporting the bug.
541 2006-06-01, Version 3.9.3
542 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
543 operating systems also profit from the changes, but I wasn't able to
544 check that.
545 * Changed the build system to find the netinet-includes under FreeBSD
546 and therefore successfully build the `liboping' library there.
548 2006-05-09, Version 3.9.2
549 * Applied a patch to the `liboping' library. Due to a bug in the
550 sequence checking the `ping' plugin stopped working after
551 approximately 7.6 days.
553 2006-05-09, Version 3.8.5
554 * Applied a patch to the `liboping' library. Due to a bug in the
555 sequence checking the `ping' plugin stopped working after
556 approximately 7.6 days.
558 2006-04-21, Version 3.9.1
559 * Build issues with Solaris and possible other architectures have been
560 resolved.
561 * Problems when building the `apache'-plugin without `libcurl' have
562 been resolved.
563 * A bug in the `ping' plugin has been fixed. Sorry folks.
565 2006-04-02, Version 3.9.0
566 * A plugin to monitor the Apache webserver has been added.
567 <http://httpd.apache.org/>
568 * A plugin to collect statistics about virtual servers using VServer.
569 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
570 this plugin :)
571 * A plugin for wireless LAN cards has been added. It monitors signal
572 strength, link quality and noise ratio..
573 * A plugin for Apple hardware sensors has been added.
574 * An option to compile collectd with different `step' and `heartbeat'
575 settings has been added. The size of RRAs is no longer static but
576 calculated based on the settings for `step' and `width'.
577 * The `ping' plugin can now be configured to use a certain TTL.
578 * A plugin to monitor the hardware sensors of Apple computers has been
579 added.
580 * The plugins `cpu', `memory', `processes' and `traffic' have been
581 ported to Mach/Darwin (Mac OS X).
582 * The `log mode' has been contributed by Christophe Kalt. It writes
583 the data into text files rather than RRD files.
585 2006-04-09, Version 3.8.4
586 * Applied patch by Vincent Stehlé which improves the disk-name
587 resolution in the `hddtemp' plugin for Linux systems.
589 2006-04-02, Version 3.8.3
590 * Applied a patch by James Byers: The MySQL plugin was not working
591 with MySQL 5.0.2 or later.
593 2006-03-14, Version 3.8.2
594 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
595 the GNU libc, because it points to `/etc/fstab' rather than
596 `/etc/mtab'.
598 2006-03-13, Version 3.8.1
599 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
600 * Fixes in the debian `postinst' and `init.d' scripts.
602 2006-03-09, Version 3.8.0
603 * The `ping' plugin no longer uses `libping' but a self written
604 library named `liboping'. With this library it's possible to ping
605 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
607 2006-02-18, Version 3.7.2
608 * A simple bug in the `battery' plugin has been fixed. It should now
609 work with ACPI based batteries as well. Thanks to Sebastian for
610 fixing this.
611 * Fixing a bug that prevented collectd to be built without librrd.
612 Thanks to Werner Heuser for reporting it.
614 2006-02-04, Version 3.7.1
615 * The new network code has been improved to build with older versions
616 of glibc.
617 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
618 to Tommie Gannert for this patch.
620 2006-01-30, Version 3.7.0
621 * The `battery' plugin has been added. It collects information about
622 laptop batteries..
623 * The MySQL plugin has been improved: It now writes two more RRD
624 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
625 * The `cpufreq' plugin now reads another file since the file it did
626 read so far causes much overhead in the kernel. Also, you need root
627 to read the old file, but not to read the new one.
628 * The `hddtemp' plugin can now be configured to connect to another
629 address and/or port than localhost.
630 * The `df' plugin now prefers `statvfs' over `statfs'.
631 * The network code has been rewritten. collectd now supports unicast
632 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
633 be set in the configfile.
635 2006-01-24, Version 3.6.2
636 * Due to a bug in the configfile handling collectd wouldn't start in
637 client mode. This released fixes this.
639 2006-01-20, Version 3.6.1
640 * Due to a bug in `configure.in' all modules and the binary were
641 linked against `libmysqlclient'. This issue is solved by this
642 release.
644 2006-01-17, Version 3.6.0
645 * A config file has been added. This allows for loading only specific
646 plugins.
647 * A `df' plugin has been added.
648 * A `mysql' plugin has been added.
649 * The `ping' plugin doesn't entirely give up hope when a socket error
650 occurred, but will back of and increase the intervals between tries.
652 2006-01-21, Version 3.5.2
653 * Fixed yet another bug in the signal handling.. Stupid typo..
654 * Improved the ping plugin to not give up on socket errors (backport
655 from 3.6.0).
657 2005-12-18, Version 3.5.1
658 * The PID-file is now deleted correctly when shutting down the daemon.
659 * SIGINT and SIGTERM are now handled correctly.
661 2005-12-16, Version 3.5.0 (Revision 326)
662 * A bug in the `load' module under Solaris has been fixed.
663 * The `users' module has been contributed by Sebastian Harl. It counts
664 currently logged in users.
665 * The CPU module now works under FreeBSD without the use of
666 `libstatgrab', however SMP support is missing.
667 * The default directories for the RRD files and the PID file now
668 depend on the compile time setting of `localstatedir'.
670 2005-11-15, Version 3.4.0 (Revision 236)
671 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
672 from gentoo's bugzilla for writing the patch.
673 * The build dependency for librrd has been removed. Binaries built
674 without librrd are client-only and will multicast their value as
675 with the `-c' argument.
676 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
677 * The newly introduced `-f' switch prevents daemon initialization
678 (forking, closing standard filehandles, etc.) Thanks to Alvaro
679 Barcellos for this patch.
681 2005-11-04, Version 3.3.0 (Revision 216)
682 * New modules have been added:
683 - `serial', for monitoring traffic on the serial interfaces
684 - `nfs', for graphing NFS procedure calls
685 - `tape', traffic from/to tape devices
686 * The memory.rrd now accepts more than 4Gig of memory.
688 2005-10-26, Version 3.2.0 (Revision 200)
689 * Support for graphing the processes has been added (thanks to Lyonel
690 Vincent)
691 * If reading from hddtemp fails collectd will increase the time
692 between polls up to one day.
693 * The init.d files have been improved.
694 * Problems with the spec file have been fixed.
696 2005-10-16, Version 3.1.0 (Revision 194)
697 * Added the `setsid' syscall to the startup code.
698 * Support for hddtemp has been added (thanks to Vincent Stehlé)
700 2005-09-30, Version 3.0.0 (Revision 184)
701 * The ability to send/receive data to/from the network (think
702 multicast) has been added.
703 * Modules have been split up into shared libraries can be loaded at
704 runtime. The biggest advantage is that the core program doesn't need
705 to be linked against an external library.
706 * A patch by George Kargiotakis has been applied: It fixes the sensors
707 behaviour then more than one sensor is being queried.
709 2005-09-16, Version 2.1.0 (Revision 172)
710 * A module for swap statistics has been added.
712 2005-09-09, Version 2.0.0 (Revision 135)
713 * Filenames can no longer be configured at program startup. The only
714 options as of this version are the directory and ping hosts.
715 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
716 Soft-IRQ statistics are added to `System'.
717 * Diskstats now collect read and write bytes, not sectors.
718 * Ping statistics can now be collected for more than one host. There
719 is no default any more: If no host is given no host will be pinged.
720 * A self-written patch for libping has been applied so it builds
721 cleanly.
723 2005-09-01, Version 1.8.1 (Revision 123)
724 * Much improved configure-script: libraries and features may now be
725 disabled.
726 * More detailed warnings/error messages when RRD update fails.
728 2005-08-29, Version 1.8.0:
729 * Support for collecting disk statistics under Solaris.
731 2005-08-25, Version 1.7.0:
732 * Support for libstatgrab[1] for load, memory usage and network
733 traffic. CPU- and disk-usage are not (yet) supported, since
734 libstatgrab returns insufficient information. I will contact the
735 authors.
736 * Improved the CPU-initialization code for Solaris. Apparently CPUs
737 aren't necessarily counted linear which is now handled correctly.
738 [1]: http://www.i-scream.org/libstatgrab/
740 2005-08-21, Version 1.6.0:
741 * Basic support for Solaris: System load and cpu-usage can be
742 collected under Solaris, too. Other stats will follow later.
743 * Many fixes in the autoconf-script
744 * Collection/Museum scripts have been added under contrib/museum
745 * collectd may now be started in unprivileged mode, though ping
746 statistics will not work.
748 2005-07-17, Version 1.5.1:
749 * Diskstats-RRDs now use major/minor for naming. Some systems have
750 weird strings as disk-names..
752 2005-07-17, Version 1.5:
753 * A new module, diskstats, has been added. It collects information
754 about the disks and partitions.
756 2005-07-11, Version 1.4.2:
757 * The meminfo module has been changed to work with more platforms
758 and/or kernel versions.
760 2005-07-10, Version 1.4.1: Correct traffic stats
761 * The traffic rrd-file is now created with DS-type `COUNTER' which I
762 forgot to correct when I changed that module.
764 2005-07-09, Version 1.4: More traffic stats
765 * Traffic is now collected for all interfaces that can be found
766 * Temperature-statistics are read from lm-sensors if available
768 2005-07-08, Version 1.3: CPU stats
769 * Collecting CPU statistics now
771 2004-07-12, Version 1.2: Using syslog
772 * collectd is now using the syslog facility to report errors, warnings
773 and the like..
774 * The default directory is now /var/db/collectd
776 2004-07-10, Version 1.1: Minor changes
777 * Nothing really useful to say ;)
779 2004-07-09, Version 1.0: Initial Version
780 * The following modules are provided:
781 * Load average
782 * Ping time
783 * Traffic
784 * Memory info
