1 2008-03-29, Version 4.3.2
2 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
3 `Persist' threshold options.
4 * collectd: Fix handling of missing values in the global value cache.
5 * collectd: Improved error messages when parsing the configuration.
6 * sensors plugin: Fix temperature collection with libsensors4.
7 * unixsock plugin: Fix mixed input and output operation on streams.
8 * wireless plugin: Fix reading noise value.
10 2008-03-05, Version 4.3.1
11 * exec plugin: Set supplementary group IDs.
12 * network plugin:
13 + Use `memcpy' when constructing/parsing a package to avoid
14 alignment problems on weird architectures, such as Sparc.
15 + Translate doubles to/from the x86 byte representation to ensure
16 cross-platform compatibility.
17 * ping plugin: Correct the handling of the `TTL' setting.
18 * swap plugin: Reapply a patch for Solaris.
19 * tcpconns plugin: Portability improvements.
21 2008-02-18, Version 4.3.0
22 * collectd: Notifications have been added to the daemon. Notifications
23 are status messages that may be associated with a data instance.
24 * collectd: Threshold checking has been added to the daemon. This
25 means that you can configure threshold values for each data
26 instance. If this threshold is exceeded a notification will be
27 created.
28 * collectd: The new `FQDNLookup' option tells the daemon to use the
29 full qualified domain name as the hostname, not just the host part
30 es returned by `gethostname(2)'.
31 * collectd: Support for more than one `TypesDB' file has been added.
32 This is useful when one such file is included in a package but one
33 wants to add custom type definitions.
34 * collectd: The `Include' config option has been expanded to handle
35 entire directories and shell wildcards.
36 * collectdmon: The new `collectdmon' binary detects when collectd
37 terminates and automatically restarts it again.
38 * csv plugin: The CSV plugin is now able to store counter values as a
39 rate, using the `StoreRates' configuration option.
40 * exec plugin: Handling of notifications has been added and the
41 ability to pass arguments to the executed programs has been added.
42 * hddtemp plugin: The new `TranslateDevicename' option lets you
43 disable the translation from device names to major-minor-numbers.
44 * logfile plugin: Handling of notifications has been added.
45 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
46 domain name lookups in this plugin.
47 * perl plugin: Many internal changes added support for handling multiple
48 threads making the plugin reasonably usable inside collectd. The API has
49 been extended to support notifications and export global variables to
50 Perl plugins; callbacks now have to be identified by name rather than a
51 pointer to a subroutine. The plugin is no longer experimental.
52 * uuid plugin: The new UUID plugin sets the hostname to an unique
53 identifier for this host. This is meant for setups where each client
54 may migrate to another physical host, possibly going through one or
55 more name changes in the process. Thanks to Richard Jones from
56 Red Hat's Emerging Technology group for this plugin.
57 * libvirt: The new libvirt plugin uses the `libvirt' library to query
58 CPU, disk and network statistics about guest systems on the same
59 physical server. Thanks to Richard Jones from Red Hat's Emerging
60 Technology group for this plugin.
62 2008-03-29, Version 4.2.6
63 * collectd: Improved error messages when parsing the configuration.
64 * sensors plugin: Fix temperature collection with libsensors4.
65 * unixsock plugin: Fix mixed input and output operation on streams.
66 * wireless plugin: Fix reading noise value.
68 2008-03-04, Version 4.2.5
69 * apache plugin: Improved initialization and error messages.
70 * exec plugin: Set supplementary group IDs.
71 * network plugin:
72 + Create separate threads for reading from the socket and parsing
73 and dispatching incoming packets. Versions prior to this may have
74 problems in high-load situations, where the socket receive buffers
75 overflows, resulting in gaps in the data.
76 + Use `memcpy' when constructing/parsing a package to avoid
77 alignment problems on weird architectures, such as Sparc.
78 + Translate doubles to/from the x86 byte representation to ensure
79 cross-platform compatibility.
80 * ping plugin: Correct the handling of the `TTL' setting.
81 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
82 * swap plugin: Reapply a patch for Solaris.
83 * tcpconns plugin: Portability improvements.
85 2008-01-21, Version 4.2.4
86 * unixsock plugin: A bug in the unixsock plugin caused it not to set
87 the permission on the socket as documented in the manpage. Thanks to
88 Evgeny Chukreev for fixing this issue.
89 * collectd: The documentation has been improved.
91 2007-12-28, Version 4.2.3
92 * sensors plugin: Updated the plugin to build and work with version 3
93 of the libsensors library.
95 2007-12-15, Version 4.2.2
96 * nginx plugin: Incorrect comparison of strings lead to a segfault
97 when using the plugin. Thanks to Saulius Grigaliunas for fixing
98 this.
99 * logfile plugin: The config option `Timestamp' was handled
100 incorrectly and basically always active. Thanks to Luke Heberling
101 for fixing this.
103 2007-11-08, Version 4.2.1
104 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
105 enabled on the host.
106 * snmp plugin: Fix a memory leak.
108 2007-10-27, Version 4.2.0
109 * collectd: The new config option `Include' lets you include other
110 configfiles and thus split up your config into smaller parts. This
111 may be especially interesting for the snmp plugin to keep the data
112 definitions separate from the host definitions.
113 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
114 (number of connections, octets and packets for each service and
115 destination). Thanks to Sebastian Harl for this plugin.
116 * memcached plugin: The new `memcached' plugin connects to a memcached
117 daemon process and collects statistics of this distributed caching
118 system. Thanks to Antony Dovgal for contributing this plugin.
119 * nginx plugin: The new `nginx' plugin reads the status page of an
120 nginx daemon and saves the handled connections and requests.
121 * perl plugin: Many changes, including the added `EnableDebugger'
122 config option which lets you debug your Perl plugins more easily.
123 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
124 be more thread-safe otherwise by locking calls to the library.
125 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
126 correct the values returned by SNMP-agents. If a <data> block is
127 defined as `table' the instance is now optional. The sequence number
128 is used as the type-instance in this case. The new `InstancePrefix'
129 option allows to add arbitrary prefixes to the type-instance.
130 * tcpconns plugin: The new `tcpconns' plugin collects the number of
131 certain TCP connections and what state they're in. This can be used
132 to see how many connections your FTP server has to handle or how
133 many outgoing connections your mailserver has open.
135 2008-01-11, Version 4.1.6
136 * unixsock plugin: A bug in the unixsock plugin caused it not to set
137 the permission on the socket as documented in the manpage. Thanks to
138 Evgeny Chukreev for fixing this issue.
139 * collectd: The documentation has been improved.
141 2007-12-27, Version 4.1.5
142 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
143 memory situations.
144 * sensors plugin: Updated the plugin to build and work with version 3
145 of the libsensors library.
147 2007-11-08, Version 4.1.4
148 * Build system: Improve detection of the rrd library, especially if
149 it's in a non-standard location.
150 * Build system: A bug when parsing the argument for
151 `--with-libnetsnmp' has been fixed.
152 * collectd: Implement `strerror_r' if the libc doesn't provide it.
153 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
154 a deadlock or delay when shutting down the daemon.
155 * snmp plugin: Fix a memory leak.
157 2007-10-24, Version 4.1.3
158 * collectd: A build issue under Solaris has been resolved by renaming
159 data types.
160 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
161 be more thread-safe otherwise by locking calls to the library.
163 2007-09-28, Version 4.1.2
164 * apcups plugin: Fix reporting of the `load percent' data.
165 * wireless plugin: Correct the handling of cards returning signal and
166 noise quality as percentage.
167 * perl plugin: Fix a possible buffer overflow in get_module_name().
168 * build system: Further improve the detection of libraries.
169 * netlink plugin: Build issues under some older versions of the Linux
170 includes (i. e. Debian Sarge) have been fixed.
171 * snmp plugin: Fix a potential segfault when a host times out. Add
172 support for the `timeticks' type.
174 2007-09-12, Version 4.1.1
175 * Build system: The detection of `libnetlink' has been improved.
176 * collectd: The documentation has been fixed in numerous places.
177 * exec plugin: Setting the group under which to run a program has been
178 fixed.
179 * collectd: The `sstrerror' function was improved to work correctly
180 with the broken GNU version of `strerror_r'.
181 * collectd: Write an error message to STDERR when loading of a plugin
182 fails.
183 * apcups plugin: Fix the `types' used to submit the values: They still
184 has an `apcups_' prefix which doesn't work anymore.
185 * rrdtool plugin: Create new RRD-files with the `begin' time set to
186 whatever the client thinks is `now'..
188 2007-09-01, Version 4.1.0
189 * Build system: The build system has been changed to automatically
190 disable all plugins, which are missing dependencies. The dependency
191 checking has been removed from the plugins themselves to remove
192 redundancy.
193 * Flexible interval: The interval of collected data is now sent along
194 with the data itself over the network, so that the interval-settings
195 of server and clients no longer needs to match.
196 * netlink plugin: The new `netlink' plugin connects to the Linux
197 kernel using a netlink socket and uses it to query information about
198 interfaces, qdiscs and classes.
199 * rrdtool plugin: The cache is now dumped to disk in an extra thread
200 to not block data collection.
201 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
202 network devices, such as switches, routers, thermometers, rack
203 monitoring servers, etc. The collectd-snmp(5) manpage documents this
204 plugin.
205 * unixsock plugin: Added the `LISTVAL' command.
206 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
207 of music played with xmms.
209 2007-09-28, Version 4.0.9
210 * apcups plugin: Fix reporting of the `load percent' data.
211 * wireless plugin: Correct the handling of cards returning signal and
212 noise quality as percentage.
213 * perl plugin: Fix a possible buffer overflow in get_module_name().
215 2007-09-12, Version 4.0.8
216 * collectd: The `sstrerror' function was improved to work correctly
217 with the broken GNU version of `strerror_r'.
218 * collectd: Write an error message to STDERR when loading of a plugin
219 fails.
220 * apcups plugin: Fix the `types' used to submit the values: They still
221 has an `apcups_' prefix which doesn't work anymore.
222 * rrdtool plugin: Create new RRD-files with the `begin' time set to
223 whatever the client thinks is `now'..
225 2007-08-26, Version 4.0.7
226 * documentation: Some typos have been fixed and some information has
227 been improved.
228 * build system: Many fixes for detecting libraries in unusual places,
229 such as on RedHat systems. The affected libraries are `libcurl',
230 `libmysql', and `libupsclient'.
231 * network plugin: Allow the `Port' option to be specified as a number
232 (i. e. without quotes).
233 * nut plugin: A fix allows linking the nut plugin against
234 libupsclient, version >= 2.2.0.
235 * processes plugin: Fix a potential segmentation fault.
237 2007-07-30, Version 4.0.6
238 * sensors plugin: Fix the ignorelist functionality: Only the `type
239 instance' was used to match against the list, but the documentation
240 told otherwise. This release fixes the code, so it complies with the
241 documentation.
242 * syslog plugin: Call `openlog' right when the plugin is loaded, so
243 configuration messages will end up in the logging facility.
244 * conrtib/fedora: The contributed specfile for Fedora has been
245 updated.
247 2007-07-05, Version 4.0.5
248 * Portability: More fixes for OpenBSD have been included.
250 2007-06-24, Version 4.0.4
251 * cpu plugin: Fixed the Solaris code.
252 * dns plugin: Fixed a build issue for OpenBSD.
253 * interface plugin: Fixed the Solaris code.
254 * load plugin: Fixed the alternative `/proc' Linux code.
255 * memory plugin: Fixed the Solaris code.
256 * oconfig: Don't require `-lfl' anymore.
258 2007-06-19, Version 4.0.3
259 * cpu plugin: Fix the Darwin / Mac OS X code.
260 * ping plugin: Use the return value of `getpid', not its address.
261 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
262 initialized correctly.
263 * configure: Added `--with-nan-emulation' to aid cross compilation.
265 2007-06-12, Version 4.0.2
266 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
267 they're given in numerically form.
269 2007-06-07, Version 4.0.1
270 * iptables plugin: A bug in the configuration routine has been fixed.
271 Setting a comment in the configfile will no longer cause a
272 segmentation fault.
274 2007-06-03, Version 4.0.0
275 * collectd: The plugin-infrastructure has been changed to allow for
276 more types of plugins, namely `write' and `log' plugins.
277 * collectd: The read-function has been changed to read many plugins in
278 parallel, using threads. Thus, plugins generally need to use
279 thread-safe functions from now on.
280 * collectd: The '-t' command line options allows to perform syntax tests
281 of the configuration file and exit immediately.
282 * csv plugin: The new `csv' plugin handles output to `comma separated
283 values'-files.
284 * rrdtool plugin: The new `rrdtool' plugin handles output to
285 RRD-files. Data can be cached to combine multiple updates into one
286 write to increase IO-performance.
287 * network plugin: The new `network' plugin handles IO via the network.
288 It implements a different, much more extensible protocol which can
289 combine many values in one packet, decreasing the number of UDP-
290 packets being sent. It can read from and send to the network and
291 with the appropriate configuration even forward packets to other
292 networks.
293 * unixsock plugin: The new `unixsock' plugin provides an interface to
294 communicate with the daemon while it is running. Right now the
295 commands `GETVAL' and `PUTVAL' are implemented, but more are to
296 come.
297 * perl plugin: The new `perl' plugin allows you to write extensions
298 for collectd in the scripting-language Perl.
299 * logfile plugin: The new `logfile' plugin writes logmessages to files
300 or STDOUT or STDERR.
301 * syslog plugin: The new `syslog' plugin sends logmessages to the
302 system's syslog daemon.
303 * entropy plugin: The new `entropy' plugin collects the amount of
304 entropy currently being available to the system.
305 * exec plugin: The new `exec' plugin forks child processes and reads
306 back values provided by the forked processes.
307 * iptables plugin: The new `iptables' plugin reads counters from
308 iptables rules. Thanks to Sjoerd van der Berg for contributing this
309 plugin.
310 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
311 to Peter Holik for contributing this plugin.
312 * nut plugin: The new `nut' plugin connects the upsd of the `network
313 ups tools' and reads information about the connected UPS.
314 * apache plugin: Support for lighttpd's `BusyServers' (aka.
315 connections) field was added by Florent Monbillard.
316 * collectd-nagios: The new `collectd-nagios' binary queries values
317 from collectd, parses them and exits according to Nagios-standards.
318 * manpages: The manpages have been improved a lot.
320 2007-09-28, Version 3.11.7
321 * wireless plugin: Correct the handling of cards returning signal and
322 noise quality as percentage.
324 2007-08-31, Version 3.11.6
325 * processes plugin: Fix a potential segmentation fault.
327 2007-05-29, Version 3.11.5
328 * configure: Added `AC_SYS_LARGEFILE' for LFS.
329 * ntpd plugin: Fix a potential buffer overflow.
330 * processes plugin: Fix a bug when run under Linux 2.4. All processes
331 were accounted as `zombies'.
333 2007-04-10, Version 3.11.4
334 * dns plugin: Change the order of includes to make the plugin compile
335 under FreeBSD.
337 2007-03-30, Version 3.11.3
338 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
339 of the unused `COLLECT_KSTAT'.
341 2007-02-11, Version 3.11.2
342 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
343 NULL-pointer may have been passed to `printf' which causes a
344 segfault with some libcs.
346 2007-02-10, Version 3.11.1
347 * df plugin: Some wrong defines have been fixed so the plugin works
348 under Solaris again.
349 * dns plugin: The usage of a struct has been fixed to work with
350 non-GNU libcs.
351 * processes plugin: Some missing defines have been added so the plugin
352 compiles cleanly under FreeBSD and presumably other UNIXes.
354 2006-12-22, Version 3.11.0
355 * collectd: The new command line option `-P' makes it easier for
356 distributors to change the location of PID-files.
357 * collectd: The daemon shuts down faster now which makes it easier to
358 write init.d-scripts for it.
359 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
360 caused problems every now and then.
361 * df plugin: New config options allow to ignore certain mountpoints,
362 filesystem types or devices.
363 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
364 and interprets it. It collects traffic as well as qtype, opcode and
365 rcode counts.
366 * email plugin: Sebastian Harl has contributed this plugin which
367 counts received mails in categories (e. g. ham, spam, virus), spam
368 score (as given by SpamAssassin) and check types.
369 * mbmon plugin: Flavio Stanchina has contributed this plugin which
370 uses `mbmon' to gather information from sensors on the motherboard.
371 * processes plugin: Collect detailed statistics for configured
372 processes, that's process and thread count, CPU usage, resident
373 segment size and pagefaults.
374 * multimeter plugin: Peter Holik contributed a new plugin which
375 queries multimeters.
376 * sensors plugin: Lubos Stanek has put much effort into improving this
377 plugin, including `extended naming', collection of voltage values
378 and the possibility to ignore certain values.
380 2006-12-21, Version 3.10.4
381 * Max Kellermann has identified a bug in the server routine: When
382 opening a socket fails the daemon will (re)try opening the socket in
383 an endless loop, ultimately leading to a `EMFILE' error.
385 2006-11-04, Version 3.10.3
386 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
387 ntpd's reply was sent in more than one packet, the buffer size was
388 calculated incorrectly, resulting in the reading of uninitialized or
389 freed memory.
391 2006-11-01, Version 3.10.2
392 * The sample config file has been improved.
393 * Errors in the manpages have been corrected.
394 * The ping-plugin now adds hosts during initialization, not during
395 startup. This speeds up startup when no network connectivity is
396 available. Also, the hosts are being added later when the network is
397 available.
398 * Improved BSD-support for the df-plugin.
399 * Fixed syntax errors in the swap-plugin for Mac OS X.
400 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
401 plugin.
402 * Don't disable the mysql-plugin if connecting to the database fails
403 during initialization. Instead, try again in increasing intervals.
405 2006-07-19, Version 3.10.1
406 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
407 the apcups cannot be reached, unconnected sockets will pile up and
408 eventually lead to `Too many open files' errors.
410 2006-07-09, Version 3.10.0
411 * The `disk' plugin has been ported to Darwin.
412 * The `battery' plugin should work on many Apple computers now.
413 * The `traffic' plugin can now ignore certain interfaces. Also,
414 statistics for sent/received packets and errors have been added.
415 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
416 to Anthony Gialluca for contributing this plugin and providing me
417 with a test environment :)
418 * A plugin for monitoring an NTP instance and the local clock drift
419 has been added.
421 2006-06-25, Version 3.9.4
422 * The Solaris code in the `swap' plugin has been changed to reflect
423 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
424 working this out.
425 * The debugging system has been fixed to work with the Sun libc.
426 * When built without librrd the variable `operating_mode' could be
427 uninitialized. Thanks to David Elliot for reporting the bug.
429 2006-06-01, Version 3.9.3
430 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
431 operating systems also profit from the changes, but I wasn't able to
432 check that.
433 * Changed the build system to find the netinet-includes under FreeBSD
434 and therefore successfully build the `liboping' library there.
436 2006-05-09, Version 3.9.2
437 * Applied a patch to the `liboping' library. Due to a bug in the
438 sequence checking the `ping' plugin stopped working after
439 approximately 7.6 days.
441 2006-05-09, Version 3.8.5
442 * Applied a patch to the `liboping' library. Due to a bug in the
443 sequence checking the `ping' plugin stopped working after
444 approximately 7.6 days.
446 2006-04-21, Version 3.9.1
447 * Build issues with Solaris and possible other architectures have been
448 resolved.
449 * Problems when building the `apache'-plugin without `libcurl' have
450 been resolved.
451 * A bug in the `ping' plugin has been fixed. Sorry folks.
453 2006-04-02, Version 3.9.0
454 * A plugin to monitor the Apache webserver has been added.
455 <http://httpd.apache.org/>
456 * A plugin to collect statistics about virtual servers using VServer.
457 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
458 this plugin :)
459 * A plugin for wireless LAN cards has been added. It monitors signal
460 strength, link quality and noise ratio..
461 * A plugin for Apple hardware sensors has been added.
462 * An option to compile collectd with different `step' and `heartbeat'
463 settings has been added. The size of RRAs is no longer static but
464 calculated based on the settings for `step' and `width'.
465 * The `ping' plugin can now be configured to use a certain TTL.
466 * A plugin to monitor the hardware sensors of Apple computers has been
467 added.
468 * The plugins `cpu', `memory', `processes' and `traffic' have been
469 ported to Mach/Darwin (Mac OS X).
470 * The `log mode' has been contributed by Christophe Kalt. It writes
471 the data into text files rather than RRD files.
473 2006-04-09, Version 3.8.4
474 * Applied patch by Vincent Stehlé which improves the disk-name
475 resolution in the `hddtemp' plugin for Linux systems.
477 2006-04-02, Version 3.8.3
478 * Applied a patch by James Byers: The MySQL plugin was not working
479 with MySQL 5.0.2 or later.
481 2006-03-14, Version 3.8.2
482 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
483 the GNU libc, because it points to `/etc/fstab' rather than
484 `/etc/mtab'.
486 2006-03-13, Version 3.8.1
487 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
488 * Fixes in the debian `postinst' and `init.d' scripts.
490 2006-03-09, Version 3.8.0
491 * The `ping' plugin no longer uses `libping' but a self written
492 library named `liboping'. With this library it's possible to ping
493 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
495 2006-02-18, Version 3.7.2
496 * A simple bug in the `battery' plugin has been fixed. It should now
497 work with ACPI based batteries as well. Thanks to Sebastian for
498 fixing this.
499 * Fixing a bug that prevented collectd to be built without librrd.
500 Thanks to Werner Heuser for reporting it.
502 2006-02-04, Version 3.7.1
503 * The new network code has been improved to build with older versions
504 of glibc.
505 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
506 to Tommie Gannert for this patch.
508 2006-01-30, Version 3.7.0
509 * The `battery' plugin has been added. It collects information about
510 laptop batteries..
511 * The MySQL plugin has been improved: It now writes two more RRD
512 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
513 * The `cpufreq' plugin now reads another file since the file it did
514 read so far causes much overhead in the kernel. Also, you need root
515 to read the old file, but not to read the new one.
516 * The `hddtemp' plugin can now be configured to connect to another
517 address and/or port than localhost.
518 * The `df' plugin now prefers `statvfs' over `statfs'.
519 * The network code has been rewritten. collectd now supports unicast
520 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
521 be set in the configfile.
523 2006-01-24, Version 3.6.2
524 * Due to a bug in the configfile handling collectd wouldn't start in
525 client mode. This released fixes this.
527 2006-01-20, Version 3.6.1
528 * Due to a bug in `configure.in' all modules and the binary were
529 linked against `libmysqlclient'. This issue is solved by this
530 release.
532 2006-01-17, Version 3.6.0
533 * A config file has been added. This allows for loading only specific
534 plugins.
535 * A `df' plugin has been added.
536 * A `mysql' plugin has been added.
537 * The `ping' plugin doesn't entirely give up hope when a socket error
538 occurred, but will back of and increase the intervals between tries.
540 2006-01-21, Version 3.5.2
541 * Fixed yet another bug in the signal handling.. Stupid typo..
542 * Improved the ping plugin to not give up on socket errors (backport
543 from 3.6.0).
545 2005-12-18, Version 3.5.1
546 * The PID-file is now deleted correctly when shutting down the daemon.
547 * SIGINT and SIGTERM are now handled correctly.
549 2005-12-16, Version 3.5.0 (Revision 326)
550 * A bug in the `load' module under Solaris has been fixed.
551 * The `users' module has been contributed by Sebastian Harl. It counts
552 currently logged in users.
553 * The CPU module now works under FreeBSD without the use of
554 `libstatgrab', however SMP support is missing.
555 * The default directories for the RRD files and the PID file now
556 depend on the compile time setting of `localstatedir'.
558 2005-11-15, Version 3.4.0 (Revision 236)
559 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
560 from gentoo's bugzilla for writing the patch.
561 * The build dependency for librrd has been removed. Binaries built
562 without librrd are client-only and will multicast their value as
563 with the `-c' argument.
564 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
565 * The newly introduced `-f' switch prevents daemon initialization
566 (forking, closing standard filehandles, etc.) Thanks to Alvaro
567 Barcellos for this patch.
569 2005-11-04, Version 3.3.0 (Revision 216)
570 * New modules have been added:
571 - `serial', for monitoring traffic on the serial interfaces
572 - `nfs', for graphing NFS procedure calls
573 - `tape', traffic from/to tape devices
574 * The memory.rrd now accepts more than 4Gig of memory.
576 2005-10-26, Version 3.2.0 (Revision 200)
577 * Support for graphing the processes has been added (thanks to Lyonel
578 Vincent)
579 * If reading from hddtemp fails collectd will increase the time
580 between polls up to one day.
581 * The init.d files have been improved.
582 * Problems with the spec file have been fixed.
584 2005-10-16, Version 3.1.0 (Revision 194)
585 * Added the `setsid' syscall to the startup code.
586 * Support for hddtemp has been added (thanks to Vincent Stehlé)
588 2005-09-30, Version 3.0.0 (Revision 184)
589 * The ability to send/receive data to/from the network (think
590 multicast) has been added.
591 * Modules have been split up into shared libraries can be loaded at
592 runtime. The biggest advantage is that the core program doesn't need
593 to be linked against an external library.
594 * A patch by George Kargiotakis has been applied: It fixes the sensors
595 behaviour then more than one sensor is being queried.
597 2005-09-16, Version 2.1.0 (Revision 172)
598 * A module for swap statistics has been added.
600 2005-09-09, Version 2.0.0 (Revision 135)
601 * Filenames can no longer be configured at program startup. The only
602 options as of this version are the directory and ping hosts.
603 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
604 Soft-IRQ statistics are added to `System'.
605 * Diskstats now collect read and write bytes, not sectors.
606 * Ping statistics can now be collected for more than one host. There
607 is no default any more: If no host is given no host will be pinged.
608 * A self-written patch for libping has been applied so it builds
609 cleanly.
611 2005-09-01, Version 1.8.1 (Revision 123)
612 * Much improved configure-script: libraries and features may now be
613 disabled.
614 * More detailed warnings/error messages when RRD update fails.
616 2005-08-29, Version 1.8.0:
617 * Support for collecting disk statistics under Solaris.
619 2005-08-25, Version 1.7.0:
620 * Support for libstatgrab[1] for load, memory usage and network
621 traffic. CPU- and disk-usage are not (yet) supported, since
622 libstatgrab returns insufficient information. I will contact the
623 authors.
624 * Improved the CPU-initialization code for Solaris. Apparently CPUs
625 aren't necessarily counted linear which is now handled correctly.
626 [1]: http://www.i-scream.org/libstatgrab/
628 2005-08-21, Version 1.6.0:
629 * Basic support for Solaris: System load and cpu-usage can be
630 collected under Solaris, too. Other stats will follow later.
631 * Many fixes in the autoconf-script
632 * Collection/Museum scripts have been added under contrib/museum
633 * collectd may now be started in unprivileged mode, though ping
634 statistics will not work.
636 2005-07-17, Version 1.5.1:
637 * Diskstats-RRDs now use major/minor for naming. Some systems have
638 weird strings as disk-names..
640 2005-07-17, Version 1.5:
641 * A new module, diskstats, has been added. It collects information
642 about the disks and partitions.
644 2005-07-11, Version 1.4.2:
645 * The meminfo module has been changed to work with more platforms
646 and/or kernel versions.
648 2005-07-10, Version 1.4.1: Correct traffic stats
649 * The traffic rrd-file is now created with DS-type `COUNTER' which I
650 forgot to correct when I changed that module.
652 2005-07-09, Version 1.4: More traffic stats
653 * Traffic is now collected for all interfaces that can be found
654 * Temperature-statistics are read from lm-sensors if available
656 2005-07-08, Version 1.3: CPU stats
657 * Collecting CPU statistics now
659 2004-07-12, Version 1.2: Using syslog
660 * collectd is now using the syslog facility to report errors, warnings
661 and the like..
662 * The default directory is now /var/db/collectd
664 2004-07-10, Version 1.1: Minor changes
665 * Nothing really useful to say ;)
667 2004-07-09, Version 1.0: Initial Version
668 * The following modules are provided:
669 * Load average
670 * Ping time
671 * Traffic
672 * Memory info
