1 2008-03-05, Version 4.3.1
2 * exec plugin: Set supplementary group IDs.
4 + Use `memcpy' when constructing/parsing a package to avoid
5 alignment problems on weird architectures, such as Sparc.
6 + Translate doubles to/from the x86 byte representation to ensure
7 cross-platform compatibility.
8 * ping plugin: Correct the handling of the `TTL' setting.
9 * swap plugin: Reapply a patch for Solaris.
10 * tcpconns plugin: Portability improvements.
12 2008-02-18, Version 4.3.0
13 * collectd: Notifications have been added to the daemon. Notifications
14 are status messages that may be associated with a data instance.
15 * collectd: Threshold checking has been added to the daemon. This
16 means that you can configure threshold values for each data
17 instance. If this threshold is exceeded a notification will be
19 * collectd: The new `FQDNLookup' option tells the daemon to use the
20 full qualified domain name as the hostname, not just the host part
21 es returned by `gethostname(2)'.
22 * collectd: Support for more than one `TypesDB' file has been added.
23 This is useful when one such file is included in a package but one
24 wants to add custom type definitions.
25 * collectd: The `Include' config option has been expanded to handle
26 entire directories and shell wildcards.
27 * collectdmon: The new `collectdmon' binary detects when collectd
28 terminates and automatically restarts it again.
29 * csv plugin: The CSV plugin is now able to store counter values as a
30 rate, using the `StoreRates' configuration option.
31 * exec plugin: Handling of notifications has been added and the
32 ability to pass arguments to the executed programs has been added.
33 * hddtemp plugin: The new `TranslateDevicename' option lets you
34 disable the translation from device names to major-minor-numbers.
35 * logfile plugin: Handling of notifications has been added.
36 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
37 domain name lookups in this plugin.
38 * perl plugin: Many internal changes added support for handling multiple
39 threads making the plugin reasonably usable inside collectd. The API has
40 been extended to support notifications and export global variables to
41 Perl plugins; callbacks now have to be identified by name rather than a
42 pointer to a subroutine. The plugin is no longer experimental.
43 * uuid plugin: The new UUID plugin sets the hostname to an unique
44 identifier for this host. This is meant for setups where each client
45 may migrate to another physical host, possibly going through one or
46 more name changes in the process. Thanks to Richard Jones from
47 Red Hat's Emerging Technology group for this plugin.
48 * libvirt: The new libvirt plugin uses the `libvirt' library to query
49 CPU, disk and network statistics about guest systems on the same
50 physical server. Thanks to Richard Jones from Red Hat's Emerging
51 Technology group for this plugin.
53 2008-03-04, Version 4.2.5
54 * apache plugin: Improved initialization and error messages.
55 * exec plugin: Set supplementary group IDs.
57 + Create separate threads for reading from the socket and parsing
58 and dispatching incoming packets. Versions prior to this may have
59 problems in high-load situations, where the socket receive buffers
60 overflows, resulting in gaps in the data.
61 + Use `memcpy' when constructing/parsing a package to avoid
62 alignment problems on weird architectures, such as Sparc.
63 + Translate doubles to/from the x86 byte representation to ensure
64 cross-platform compatibility.
65 * ping plugin: Correct the handling of the `TTL' setting.
66 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
67 * swap plugin: Reapply a patch for Solaris.
68 * tcpconns plugin: Portability improvements.
70 2008-01-21, Version 4.2.4
71 * unixsock plugin: A bug in the unixsock plugin caused it not to set
72 the permission on the socket as documented in the manpage. Thanks to
73 Evgeny Chukreev for fixing this issue.
74 * collectd: The documentation has been improved.
76 2007-12-28, Version 4.2.3
77 * sensors plugin: Updated the plugin to build and work with version 3
78 of the libsensors library.
80 2007-12-15, Version 4.2.2
81 * nginx plugin: Incorrect comparison of strings lead to a segfault
82 when using the plugin. Thanks to Saulius Grigaliunas for fixing
84 * logfile plugin: The config option `Timestamp' was handled
85 incorrectly and basically always active. Thanks to Luke Heberling
88 2007-11-08, Version 4.2.1
89 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
91 * snmp plugin: Fix a memory leak.
93 2007-10-27, Version 4.2.0
94 * collectd: The new config option `Include' lets you include other
95 configfiles and thus split up your config into smaller parts. This
96 may be especially interesting for the snmp plugin to keep the data
97 definitions separate from the host definitions.
98 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
99 (number of connections, octets and packets for each service and
100 destination). Thanks to Sebastian Harl for this plugin.
101 * memcached plugin: The new `memcached' plugin connects to a memcached
102 daemon process and collects statistics of this distributed caching
103 system. Thanks to Antony Dovgal for contributing this plugin.
104 * nginx plugin: The new `nginx' plugin reads the status page of an
105 nginx daemon and saves the handled connections and requests.
106 * perl plugin: Many changes, including the added `EnableDebugger'
107 config option which lets you debug your Perl plugins more easily.
108 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
109 be more thread-safe otherwise by locking calls to the library.
110 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
111 correct the values returned by SNMP-agents. If a <data> block is
112 defined as `table' the instance is now optional. The sequence number
113 is used as the type-instance in this case. The new `InstancePrefix'
114 option allows to add arbitrary prefixes to the type-instance.
115 * tcpconns plugin: The new `tcpconns' plugin collects the number of
116 certain TCP connections and what state they're in. This can be used
117 to see how many connections your FTP server has to handle or how
118 many outgoing connections your mailserver has open.
120 2008-01-11, Version 4.1.6
121 * unixsock plugin: A bug in the unixsock plugin caused it not to set
122 the permission on the socket as documented in the manpage. Thanks to
123 Evgeny Chukreev for fixing this issue.
124 * collectd: The documentation has been improved.
126 2007-12-27, Version 4.1.5
127 * rrdtool plugin: Fix a memory leak that only occurred in very-low-
129 * sensors plugin: Updated the plugin to build and work with version 3
130 of the libsensors library.
132 2007-11-08, Version 4.1.4
133 * Build system: Improve detection of the rrd library, especially if
134 it's in a non-standard location.
135 * Build system: A bug when parsing the argument for
136 `--with-libnetsnmp' has been fixed.
137 * collectd: Implement `strerror_r' if the libc doesn't provide it.
138 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
139 a deadlock or delay when shutting down the daemon.
140 * snmp plugin: Fix a memory leak.
142 2007-10-24, Version 4.1.3
143 * collectd: A build issue under Solaris has been resolved by renaming
145 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
146 be more thread-safe otherwise by locking calls to the library.
148 2007-09-28, Version 4.1.2
149 * apcups plugin: Fix reporting of the `load percent' data.
150 * wireless plugin: Correct the handling of cards returning signal and
151 noise quality as percentage.
152 * perl plugin: Fix a possible buffer overflow in get_module_name().
153 * build system: Further improve the detection of libraries.
154 * netlink plugin: Build issues under some older versions of the Linux
155 includes (i. e. Debian Sarge) have been fixed.
156 * snmp plugin: Fix a potential segfault when a host times out. Add
157 support for the `timeticks' type.
159 2007-09-12, Version 4.1.1
160 * Build system: The detection of `libnetlink' has been improved.
161 * collectd: The documentation has been fixed in numerous places.
162 * exec plugin: Setting the group under which to run a program has been
164 * collectd: The `sstrerror' function was improved to work correctly
165 with the broken GNU version of `strerror_r'.
166 * collectd: Write an error message to STDERR when loading of a plugin
168 * apcups plugin: Fix the `types' used to submit the values: They still
169 has an `apcups_' prefix which doesn't work anymore.
170 * rrdtool plugin: Create new RRD-files with the `begin' time set to
171 whatever the client thinks is `now'..
173 2007-09-01, Version 4.1.0
174 * Build system: The build system has been changed to automatically
175 disable all plugins, which are missing dependencies. The dependency
176 checking has been removed from the plugins themselves to remove
178 * Flexible interval: The interval of collected data is now sent along
179 with the data itself over the network, so that the interval-settings
180 of server and clients no longer needs to match.
181 * netlink plugin: The new `netlink' plugin connects to the Linux
182 kernel using a netlink socket and uses it to query information about
183 interfaces, qdiscs and classes.
184 * rrdtool plugin: The cache is now dumped to disk in an extra thread
185 to not block data collection.
186 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
187 network devices, such as switches, routers, thermometers, rack
188 monitoring servers, etc. The collectd-snmp(5) manpage documents this
190 * unixsock plugin: Added the `LISTVAL' command.
191 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
192 of music played with xmms.
194 2007-09-28, Version 4.0.9
195 * apcups plugin: Fix reporting of the `load percent' data.
196 * wireless plugin: Correct the handling of cards returning signal and
197 noise quality as percentage.
198 * perl plugin: Fix a possible buffer overflow in get_module_name().
200 2007-09-12, Version 4.0.8
201 * collectd: The `sstrerror' function was improved to work correctly
202 with the broken GNU version of `strerror_r'.
203 * collectd: Write an error message to STDERR when loading of a plugin
205 * apcups plugin: Fix the `types' used to submit the values: They still
206 has an `apcups_' prefix which doesn't work anymore.
207 * rrdtool plugin: Create new RRD-files with the `begin' time set to
208 whatever the client thinks is `now'..
210 2007-08-26, Version 4.0.7
211 * documentation: Some typos have been fixed and some information has
213 * build system: Many fixes for detecting libraries in unusual places,
214 such as on RedHat systems. The affected libraries are `libcurl',
215 `libmysql', and `libupsclient'.
216 * network plugin: Allow the `Port' option to be specified as a number
217 (i. e. without quotes).
218 * nut plugin: A fix allows linking the nut plugin against
219 libupsclient, version >= 2.2.0.
220 * processes plugin: Fix a potential segmentation fault.
222 2007-07-30, Version 4.0.6
223 * sensors plugin: Fix the ignorelist functionality: Only the `type
224 instance' was used to match against the list, but the documentation
225 told otherwise. This release fixes the code, so it complies with the
227 * syslog plugin: Call `openlog' right when the plugin is loaded, so
228 configuration messages will end up in the logging facility.
229 * conrtib/fedora: The contributed specfile for Fedora has been
232 2007-07-05, Version 4.0.5
233 * Portability: More fixes for OpenBSD have been included.
235 2007-06-24, Version 4.0.4
236 * cpu plugin: Fixed the Solaris code.
237 * dns plugin: Fixed a build issue for OpenBSD.
238 * interface plugin: Fixed the Solaris code.
239 * load plugin: Fixed the alternative `/proc' Linux code.

241 * oconfig: Don't require `-lfl' anymore.
243 2007-06-19, Version 4.0.3
244 * cpu plugin: Fix the Darwin / Mac OS X code.
245 * ping plugin: Use the return value of `getpid', not its address.
246 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
247 initialized correctly.
248 * configure: Added `--with-nan-emulation' to aid cross compilation.
250 2007-06-12, Version 4.0.2
251 * hddtemp and ntpd plugin: Corrected the parsing of port numbers when
252 they're given in numerically form.
254 2007-06-07, Version 4.0.1
255 * iptables plugin: A bug in the configuration routine has been fixed.
256 Setting a comment in the configfile will no longer cause a
259 2007-06-03, Version 4.0.0
260 * collectd: The plugin-infrastructure has been changed to allow for
261 more types of plugins, namely `write' and `log' plugins.
262 * collectd: The read-function has been changed to read many plugins in
263 parallel, using threads. Thus, plugins generally need to use
264 thread-safe functions from now on.
265 * collectd: The '-t' command line options allows to perform syntax tests
266 of the configuration file and exit immediately.
267 * csv plugin: The new `csv' plugin handles output to `comma separated
269 * rrdtool plugin: The new `rrdtool' plugin handles output to
270 RRD-files. Data can be cached to combine multiple updates into one
271 write to increase IO-performance.
272 * network plugin: The new `network' plugin handles IO via the network.
273 It implements a different, much more extensible protocol which can
274 combine many values in one packet, decreasing the number of UDP-
275 packets being sent. It can read from and send to the network and
276 with the appropriate configuration even forward packets to other
278 * unixsock plugin: The new `unixsock' plugin provides an interface to
279 communicate with the daemon while it is running. Right now the
280 commands `GETVAL' and `PUTVAL' are implemented, but more are to
282 * perl plugin: The new `perl' plugin allows you to write extensions
283 for collectd in the scripting-language Perl.
284 * logfile plugin: The new `logfile' plugin writes logmessages to files
286 * syslog plugin: The new `syslog' plugin sends logmessages to the
287 system's syslog daemon.
288 * entropy plugin: The new `entropy' plugin collects the amount of
289 entropy currently being available to the system.
290 * exec plugin: The new `exec' plugin forks child processes and reads
291 back values provided by the forked processes.
292 * iptables plugin: The new `iptables' plugin reads counters from
293 iptables rules. Thanks to Sjoerd van der Berg for contributing this
295 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
296 to Peter Holik for contributing this plugin.
297 * nut plugin: The new `nut' plugin connects the upsd of the `network
298 ups tools' and reads information about the connected UPS.
299 * apache plugin: Support for lighttpd's `BusyServers' (aka.
300 connections) field was added by Florent Monbillard.
301 * collectd-nagios: The new `collectd-nagios' binary queries values
302 from collectd, parses them and exits according to Nagios-standards.
303 * manpages: The manpages have been improved a lot.
305 2007-09-28, Version 3.11.7
306 * wireless plugin: Correct the handling of cards returning signal and
307 noise quality as percentage.
309 2007-08-31, Version 3.11.6
310 * processes plugin: Fix a potential segmentation fault.
312 2007-05-29, Version 3.11.5
313 * configure: Added `AC_SYS_LARGEFILE' for LFS.
314 * ntpd plugin: Fix a potential buffer overflow.
315 * processes plugin: Fix a bug when run under Linux 2.4. All processes
316 were accounted as `zombies'.
318 2007-04-10, Version 3.11.4
319 * dns plugin: Change the order of includes to make the plugin compile
322 2007-03-30, Version 3.11.3
323 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
324 of the unused `COLLECT_KSTAT'.
326 2007-02-11, Version 3.11.2
327 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
328 NULL-pointer may have been passed to `printf' which causes a
329 segfault with some libcs.
331 2007-02-10, Version 3.11.1
332 * df plugin: Some wrong defines have been fixed so the plugin works
334 * dns plugin: The usage of a struct has been fixed to work with
336 * processes plugin: Some missing defines have been added so the plugin
337 compiles cleanly under FreeBSD and presumably other UNIXes.
339 2006-12-22, Version 3.11.0
340 * collectd: The new command line option `-P' makes it easier for
341 distributors to change the location of PID-files.
342 * collectd: The daemon shuts down faster now which makes it easier to
343 write init.d-scripts for it.
344 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
345 caused problems every now and then.
346 * df plugin: New config options allow to ignore certain mountpoints,
347 filesystem types or devices.
348 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
349 and interprets it. It collects traffic as well as qtype, opcode and
351 * email plugin: Sebastian Harl has contributed this plugin which
352 counts received mails in categories (e. g. ham, spam, virus), spam
353 score (as given by SpamAssassin) and check types.
354 * mbmon plugin: Flavio Stanchina has contributed this plugin which
355 uses `mbmon' to gather information from sensors on the motherboard.
356 * processes plugin: Collect detailed statistics for configured
357 processes, that's process and thread count, CPU usage, resident
358 segment size and pagefaults.
359 * multimeter plugin: Peter Holik contributed a new plugin which
361 * sensors plugin: Lubos Stanek has put much effort into improving this
362 plugin, including `extended naming', collection of voltage values
363 and the possibility to ignore certain values.
365 2006-12-21, Version 3.10.4
366 * Max Kellermann has identified a bug in the server routine: When
367 opening a socket fails the daemon will (re)try opening the socket in
368 an endless loop, ultimately leading to a `EMFILE' error.
370 2006-11-04, Version 3.10.3
371 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
372 ntpd's reply was sent in more than one packet, the buffer size was
373 calculated incorrectly, resulting in the reading of uninitialized or
376 2006-11-01, Version 3.10.2
377 * The sample config file has been improved.
378 * Errors in the manpages have been corrected.
379 * The ping-plugin now adds hosts during initialization, not during
380 startup. This speeds up startup when no network connectivity is
381 available. Also, the hosts are being added later when the network is
383 * Improved BSD-support for the df-plugin.
384 * Fixed syntax errors in the swap-plugin for Mac OS X.
385 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
387 * Don't disable the mysql-plugin if connecting to the database fails
388 during initialization. Instead, try again in increasing intervals.
390 2006-07-19, Version 3.10.1
391 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
392 the apcups cannot be reached, unconnected sockets will pile up and
393 eventually lead to `Too many open files' errors.
395 2006-07-09, Version 3.10.0
396 * The `disk' plugin has been ported to Darwin.
397 * The `battery' plugin should work on many Apple computers now.
398 * The `traffic' plugin can now ignore certain interfaces. Also,
399 statistics for sent/received packets and errors have been added.
400 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
401 to Anthony Gialluca for contributing this plugin and providing me
402 with a test environment :)
403 * A plugin for monitoring an NTP instance and the local clock drift
406 2006-06-25, Version 3.9.4
407 * The Solaris code in the `swap' plugin has been changed to reflect
408 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
410 * The debugging system has been fixed to work with the Sun libc.
411 * When built without librrd the variable `operating_mode' could be
412 uninitialized. Thanks to David Elliot for reporting the bug.
414 2006-06-01, Version 3.9.3
415 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
416 operating systems also profit from the changes, but I wasn't able to
418 * Changed the build system to find the netinet-includes under FreeBSD
419 and therefore successfully build the `liboping' library there.
421 2006-05-09, Version 3.9.2
422 * Applied a patch to the `liboping' library. Due to a bug in the
423 sequence checking the `ping' plugin stopped working after
424 approximately 7.6 days.
426 2006-05-09, Version 3.8.5
427 * Applied a patch to the `liboping' library. Due to a bug in the
428 sequence checking the `ping' plugin stopped working after
429 approximately 7.6 days.
431 2006-04-21, Version 3.9.1
432 * Build issues with Solaris and possible other architectures have been
434 * Problems when building the `apache'-plugin without `libcurl' have
436 * A bug in the `ping' plugin has been fixed. Sorry folks.
438 2006-04-02, Version 3.9.0
439 * A plugin to monitor the Apache webserver has been added.
440 <http://httpd.apache.org/>
441 * A plugin to collect statistics about virtual servers using VServer.
442 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
444 * A plugin for wireless LAN cards has been added. It monitors signal
445 strength, link quality and noise ratio..
446 * A plugin for Apple hardware sensors has been added.
447 * An option to compile collectd with different `step' and `heartbeat'
448 settings has been added. The size of RRAs is no longer static but
449 calculated based on the settings for `step' and `width'.
450 * The `ping' plugin can now be configured to use a certain TTL.
451 * A plugin to monitor the hardware sensors of Apple computers has been
453 * The plugins `cpu', `memory', `processes' and `traffic' have been
454 ported to Mach/Darwin (Mac OS X).
455 * The `log mode' has been contributed by Christophe Kalt. It writes
456 the data into text files rather than RRD files.
458 2006-04-09, Version 3.8.4
459 * Applied patch by Vincent Stehlé which improves the disk-name
460 resolution in the `hddtemp' plugin for Linux systems.
462 2006-04-02, Version 3.8.3
463 * Applied a patch by James Byers: The MySQL plugin was not working
464 with MySQL 5.0.2 or later.
466 2006-03-14, Version 3.8.2
467 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
468 the GNU libc, because it points to `/etc/fstab' rather than
471 2006-03-13, Version 3.8.1
472 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
473 * Fixes in the debian `postinst' and `init.d' scripts.
475 2006-03-09, Version 3.8.0
476 * The `ping' plugin no longer uses `libping' but a self written
477 library named `liboping'. With this library it's possible to ping
478 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
480 2006-02-18, Version 3.7.2
481 * A simple bug in the `battery' plugin has been fixed. It should now
482 work with ACPI based batteries as well. Thanks to Sebastian for
484 * Fixing a bug that prevented collectd to be built without librrd.
485 Thanks to Werner Heuser for reporting it.
487 2006-02-04, Version 3.7.1
488 * The new network code has been improved to build with older versions
490 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
491 to Tommie Gannert for this patch.
493 2006-01-30, Version 3.7.0
494 * The `battery' plugin has been added. It collects information about
496 * The MySQL plugin has been improved: It now writes two more RRD
497 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
498 * The `cpufreq' plugin now reads another file since the file it did
499 read so far causes much overhead in the kernel. Also, you need root
500 to read the old file, but not to read the new one.
501 * The `hddtemp' plugin can now be configured to connect to another
502 address and/or port than localhost.
503 * The `df' plugin now prefers `statvfs' over `statfs'.
504 * The network code has been rewritten. collectd now supports unicast
505 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
506 be set in the configfile.
508 2006-01-24, Version 3.6.2
509 * Due to a bug in the configfile handling collectd wouldn't start in
510 client mode. This released fixes this.
512 2006-01-20, Version 3.6.1
513 * Due to a bug in `configure.in' all modules and the binary were
514 linked against `libmysqlclient'. This issue is solved by this
517 2006-01-17, Version 3.6.0
518 * A config file has been added. This allows for loading only specific
520 * A `df' plugin has been added.
521 * A `mysql' plugin has been added.
522 * The `ping' plugin doesn't entirely give up hope when a socket error
523 occurred, but will back of and increase the intervals between tries.
525 2006-01-21, Version 3.5.2
526 * Fixed yet another bug in the signal handling.. Stupid typo..
527 * Improved the ping plugin to not give up on socket errors (backport
530 2005-12-18, Version 3.5.1
531 * The PID-file is now deleted correctly when shutting down the daemon.
532 * SIGINT and SIGTERM are now handled correctly.
534 2005-12-16, Version 3.5.0 (Revision 326)
535 * A bug in the `load' module under Solaris has been fixed.
536 * The `users' module has been contributed by Sebastian Harl. It counts
537 currently logged in users.
538 * The CPU module now works under FreeBSD without the use of
539 `libstatgrab', however SMP support is missing.
540 * The default directories for the RRD files and the PID file now
541 depend on the compile time setting of `localstatedir'.
543 2005-11-15, Version 3.4.0 (Revision 236)
544 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
545 from gentoo's bugzilla for writing the patch.
546 * The build dependency for librrd has been removed. Binaries built
547 without librrd are client-only and will multicast their value as
548 with the `-c' argument.
549 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
550 * The newly introduced `-f' switch prevents daemon initialization
551 (forking, closing standard filehandles, etc.) Thanks to Alvaro
552 Barcellos for this patch.
554 2005-11-04, Version 3.3.0 (Revision 216)
555 * New modules have been added:
556 - `serial', for monitoring traffic on the serial interfaces
557 - `nfs', for graphing NFS procedure calls
558 - `tape', traffic from/to tape devices
559 * The memory.rrd now accepts more than 4Gig of memory.
561 2005-10-26, Version 3.2.0 (Revision 200)
562 * Support for graphing the processes has been added (thanks to Lyonel
564 * If reading from hddtemp fails collectd will increase the time
565 between polls up to one day.
566 * The init.d files have been improved.
567 * Problems with the spec file have been fixed.
569 2005-10-16, Version 3.1.0 (Revision 194)
570 * Added the `setsid' syscall to the startup code.
571 * Support for hddtemp has been added (thanks to Vincent Stehlé)
573 2005-09-30, Version 3.0.0 (Revision 184)
574 * The ability to send/receive data to/from the network (think
575 multicast) has been added.
576 * Modules have been split up into shared libraries can be loaded at
577 runtime. The biggest advantage is that the core program doesn't need
578 to be linked against an external library.
579 * A patch by George Kargiotakis has been applied: It fixes the sensors
580 behaviour then more than one sensor is being queried.
582 2005-09-16, Version 2.1.0 (Revision 172)
583 * A module for swap statistics has been added.
585 2005-09-09, Version 2.0.0 (Revision 135)
586 * Filenames can no longer be configured at program startup. The only
587 options as of this version are the directory and ping hosts.
588 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
589 Soft-IRQ statistics are added to `System'.
590 * Diskstats now collect read and write bytes, not sectors.
591 * Ping statistics can now be collected for more than one host. There
592 is no default any more: If no host is given no host will be pinged.
593 * A self-written patch for libping has been applied so it builds
596 2005-09-01, Version 1.8.1 (Revision 123)
597 * Much improved configure-script: libraries and features may now be
599 * More detailed warnings/error messages when RRD update fails.
601 2005-08-29, Version 1.8.0:
602 * Support for collecting disk statistics under Solaris.
604 2005-08-25, Version 1.7.0:
605 * Support for libstatgrab[1] for load, memory usage and network
606 traffic. CPU- and disk-usage are not (yet) supported, since
607 libstatgrab returns insufficient information. I will contact the
609 * Improved the CPU-initialization code for Solaris. Apparently CPUs
610 aren't necessarily counted linear which is now handled correctly.
611 [1]: http://www.i-scream.org/libstatgrab/
613 2005-08-21, Version 1.6.0:
614 * Basic support for Solaris: System load and cpu-usage can be
615 collected under Solaris, too. Other stats will follow later.
616 * Many fixes in the autoconf-script
617 * Collection/Museum scripts have been added under contrib/museum
618 * collectd may now be started in unprivileged mode, though ping
619 statistics will not work.
621 2005-07-17, Version 1.5.1:
622 * Diskstats-RRDs now use major/minor for naming. Some systems have
623 weird strings as disk-names..
625 2005-07-17, Version 1.5:
626 * A new module, diskstats, has been added. It collects information
627 about the disks and partitions.
629 2005-07-11, Version 1.4.2:
630 * The meminfo module has been changed to work with more platforms
631 and/or kernel versions.
633 2005-07-10, Version 1.4.1: Correct traffic stats
634 * The traffic rrd-file is now created with DS-type `COUNTER' which I
635 forgot to correct when I changed that module.
637 2005-07-09, Version 1.4: More traffic stats
638 * Traffic is now collected for all interfaces that can be found
639 * Temperature-statistics are read from lm-sensors if available
641 2005-07-08, Version 1.3: CPU stats
642 * Collecting CPU statistics now
644 2004-07-12, Version 1.2: Using syslog
645 * collectd is now using the syslog facility to report errors, warnings
647 * The default directory is now /var/db/collectd
649 2004-07-10, Version 1.1: Minor changes
650 * Nothing really useful to say ;)
652 2004-07-09, Version 1.0: Initial Version
653 * The following modules are provided:
