19 2008-04-22, Version 4.3.3
20 * build system: Improved detection of several libraries, especially if
21 they are in non-standard paths.
22 * build system: Portability fixes: Automatically define "_REENTRANT"
23 if the libc expects it.
24 * collectd: Error and warning messages have been improved.
25 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
27 * apache plugin: Allocate new memory when reading a webpage instead of
28 using a buffer of static size.
29 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
31 * hddtemp plugin: Error and warning messages have been improved.
32 * sensors plugin: Fix sensor collection for some chip types.
34 2008-03-29, Version 4.3.2
35 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
36 `Persist' threshold options.
37 * collectd: Fix handling of missing values in the global value cache.
38 * collectd: Improved error messages when parsing the configuration.
39 * sensors plugin: Fix temperature collection with libsensors4.
40 * unixsock plugin: Fix mixed input and output operation on streams.
41 * wireless plugin: Fix reading noise value.
43 2008-03-05, Version 4.3.1
44 * exec plugin: Set supplementary group IDs.
46 + Use `memcpy' when constructing/parsing a package to avoid
47 alignment problems on weird architectures, such as Sparc.
48 + Translate doubles to/from the x86 byte representation to ensure
49 cross-platform compatibility.
50 * ping plugin: Correct the handling of the `TTL' setting.
51 * swap plugin: Reapply a patch for Solaris.
52 * tcpconns plugin: Portability improvements.
54 2008-02-18, Version 4.3.0
55 * collectd: Notifications have been added to the daemon. Notifications
56 are status messages that may be associated with a data instance.
57 * collectd: Threshold checking has been added to the daemon. This
58 means that you can configure threshold values for each data
59 instance. If this threshold is exceeded a notification will be
61 * collectd: The new `FQDNLookup' option tells the daemon to use the
62 full qualified domain name as the hostname, not just the host part
63 es returned by `gethostname(2)'.
64 * collectd: Support for more than one `TypesDB' file has been added.
65 This is useful when one such file is included in a package but one
66 wants to add custom type definitions.
67 * collectd: The `Include' config option has been expanded to handle
68 entire directories and shell wildcards.
69 * collectdmon: The new `collectdmon' binary detects when collectd
70 terminates and automatically restarts it again.
71 * csv plugin: The CSV plugin is now able to store counter values as a
72 rate, using the `StoreRates' configuration option.
73 * exec plugin: Handling of notifications has been added and the
74 ability to pass arguments to the executed programs has been added.
75 * hddtemp plugin: The new `TranslateDevicename' option lets you
76 disable the translation from device names to major-minor-numbers.
77 * logfile plugin: Handling of notifications has been added.
78 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
79 domain name lookups in this plugin.
80 * perl plugin: Many internal changes added support for handling multiple
81 threads making the plugin reasonably usable inside collectd. The API has
82 been extended to support notifications and export global variables to
83 Perl plugins; callbacks now have to be identified by name rather than a
84 pointer to a subroutine. The plugin is no longer experimental.
85 * uuid plugin: The new UUID plugin sets the hostname to an unique
86 identifier for this host. This is meant for setups where each client
87 may migrate to another physical host, possibly going through one or
88 more name changes in the process. Thanks to Richard Jones from
89 Red Hat's Emerging Technology group for this plugin.
90 * libvirt: The new libvirt plugin uses the `libvirt' library to query
91 CPU, disk and network statistics about guest systems on the same
92 physical server. Thanks to Richard Jones from Red Hat's Emerging
93 Technology group for this plugin.
95 2008-04-22, Version 4.2.7
96 * build system: Improved detection of several libraries, especially if
97 they are in non-standard paths.
98 * build system: Portability fixes: Automatically define "_REENTRANT"
99 if the libc expects it.
100 * collectd: Error and warning messages have been improved.
101 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
103 * apache plugin: Allocate new memory when reading a webpage instead of
104 using a buffer of static size.
105 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
107 * hddtemp plugin: Error and warning messages have been improved.
108 * sensors plugin: Fix sensor collection for some chip types.
110 2008-03-29, Version 4.2.6
111 * collectd: Improved error messages when parsing the configuration.
112 * sensors plugin: Fix temperature collection with libsensors4.
113 * unixsock plugin: Fix mixed input and output operation on streams.
114 * wireless plugin: Fix reading noise value.
116 2008-03-04, Version 4.2.5
117 * apache plugin: Improved initialization and error messages.
118 * exec plugin: Set supplementary group IDs.
120 + Create separate threads for reading from the socket and parsing
121 and dispatching incoming packets. Versions prior to this may have
122 problems in high-load situations, where the socket receive buffers
123 overflows, resulting in gaps in the data.
124 + Use `memcpy' when constructing/parsing a package to avoid
125 alignment problems on weird architectures, such as Sparc.
126 + Translate doubles to/from the x86 byte representation to ensure
127 cross-platform compatibility.
128 * ping plugin: Correct the handling of the `TTL' setting.
129 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
130 * swap plugin: Reapply a patch for Solaris.
131 * tcpconns plugin: Portability improvements.
133 2008-01-21, Version 4.2.4
134 * unixsock plugin: A bug in the unixsock plugin caused it not to set
135 the permission on the socket as documented in the manpage. Thanks to
136 Evgeny Chukreev for fixing this issue.
137 * collectd: The documentation has been improved.
139 2007-12-28, Version 4.2.3
140 * sensors plugin: Updated the plugin to build and work with version 3
141 of the libsensors library.
143 2007-12-15, Version 4.2.2
144 * nginx plugin: Incorrect comparison of strings lead to a segfault
145 when using the plugin. Thanks to Saulius Grigaliunas for fixing
147 * logfile plugin: The config option `Timestamp' was handled
148 incorrectly and basically always active. Thanks to Luke Heberling
151 2007-11-08, Version 4.2.1
152 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
154 * snmp plugin: Fix a memory leak.
156 2007-10-27, Version 4.2.0
157 * collectd: The new config option `Include' lets you include other
158 configfiles and thus split up your config into smaller parts. This
159 may be especially interesting for the snmp plugin to keep the data
160 definitions separate from the host definitions.
161 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
162 (number of connections, octets and packets for each service and
163 destination). Thanks to Sebastian Harl for this plugin.
164 * memcached plugin: The new `memcached' plugin connects to a memcached
165 daemon process and collects statistics of this distributed caching
166 system. Thanks to Antony Dovgal for contributing this plugin.
167 * nginx plugin: The new `nginx' plugin reads the status page of an
168 nginx daemon and saves the handled connections and requests.
169 * perl plugin: Many changes, including the added `EnableDebugger'
170 config option which lets you debug your Perl plugins more easily.
171 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
172 be more thread-safe otherwise by locking calls to the library.
173 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
174 correct the values returned by SNMP-agents. If a <data> block is
175 defined as `table' the instance is now optional. The sequence number
176 is used as the type-instance in this case. The new `InstancePrefix'
177 option allows to add arbitrary prefixes to the type-instance.
178 * tcpconns plugin: The new `tcpconns' plugin collects the number of
179 certain TCP connections and what state they're in. This can be used
180 to see how many connections your FTP server has to handle or how
181 many outgoing connections your mailserver has open.
183 2008-01-11, Version 4.1.6
184 * unixsock plugin: A bug in the unixsock plugin caused it not to set
185 the permission on the socket as documented in the manpage. Thanks to
186 Evgeny Chukreev for fixing this issue.
187 * collectd: The documentation has been improved.
189 2007-12-27, Version 4.1.5

193 of the libsensors library.
195 2007-11-08, Version 4.1.4
196 * Build system: Improve detection of the rrd library, especially if
197 it's in a non-standard location.
198 * Build system: A bug when parsing the argument for
199 `--with-libnetsnmp' has been fixed.
200 * collectd: Implement `strerror_r' if the libc doesn't provide it.
201 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
202 a deadlock or delay when shutting down the daemon.
203 * snmp plugin: Fix a memory leak.
205 2007-10-24, Version 4.1.3
206 * collectd: A build issue under Solaris has been resolved by renaming
208 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
209 be more thread-safe otherwise by locking calls to the library.
211 2007-09-28, Version 4.1.2
212 * apcups plugin: Fix reporting of the `load percent' data.
213 * wireless plugin: Correct the handling of cards returning signal and
214 noise quality as percentage.

223 * Build system: The detection of `libnetlink' has been improved.
224 * collectd: The documentation has been fixed in numerous places.
225 * exec plugin: Setting the group under which to run a program has been
227 * collectd: The `sstrerror' function was improved to work correctly
228 with the broken GNU version of `strerror_r'.
229 * collectd: Write an error message to STDERR when loading of a plugin
231 * apcups plugin: Fix the `types' used to submit the values: They still
232 has an `apcups_' prefix which doesn't work anymore.
233 * rrdtool plugin: Create new RRD-files with the `begin' time set to
234 whatever the client thinks is `now'..
236 2007-09-01, Version 4.1.0
237 * Build system: The build system has been changed to automatically
238 disable all plugins, which are missing dependencies. The dependency
239 checking has been removed from the plugins themselves to remove
241 * Flexible interval: The interval of collected data is now sent along
242 with the data itself over the network, so that the interval-settings
243 of server and clients no longer needs to match.
244 * netlink plugin: The new `netlink' plugin connects to the Linux
245 kernel using a netlink socket and uses it to query information about
246 interfaces, qdiscs and classes.
247 * rrdtool plugin: The cache is now dumped to disk in an extra thread
248 to not block data collection.
249 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
250 network devices, such as switches, routers, thermometers, rack
251 monitoring servers, etc. The collectd-snmp(5) manpage documents this
253 * unixsock plugin: Added the `LISTVAL' command.
254 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
255 of music played with xmms.
257 2007-09-28, Version 4.0.9
258 * apcups plugin: Fix reporting of the `load percent' data.
259 * wireless plugin: Correct the handling of cards returning signal and
260 noise quality as percentage.
261 * perl plugin: Fix a possible buffer overflow in get_module_name().
263 2007-09-12, Version 4.0.8
264 * collectd: The `sstrerror' function was improved to work correctly
265 with the broken GNU version of `strerror_r'.
266 * collectd: Write an error message to STDERR when loading of a plugin
268 * apcups plugin: Fix the `types' used to submit the values: They still
269 has an `apcups_' prefix which doesn't work anymore.
270 * rrdtool plugin: Create new RRD-files with the `begin' time set to
271 whatever the client thinks is `now'..
273 2007-08-26, Version 4.0.7
274 * documentation: Some typos have been fixed and some information has
276 * build system: Many fixes for detecting libraries in unusual places,
277 such as on RedHat systems. The affected libraries are `libcurl',
278 `libmysql', and `libupsclient'.
279 * network plugin: Allow the `Port' option to be specified as a number
280 (i. e. without quotes).
281 * nut plugin: A fix allows linking the nut plugin against
282 libupsclient, version >= 2.2.0.
283 * processes plugin: Fix a potential segmentation fault.
285 2007-07-30, Version 4.0.6
286 * sensors plugin: Fix the ignorelist functionality: Only the `type
287 instance' was used to match against the list, but the documentation
288 told otherwise. This release fixes the code, so it complies with the
290 * syslog plugin: Call `openlog' right when the plugin is loaded, so
291 configuration messages will end up in the logging facility.
292 * conrtib/fedora: The contributed specfile for Fedora has been
295 2007-07-05, Version 4.0.5
296 * Portability: More fixes for OpenBSD have been included.
298 2007-06-24, Version 4.0.4
299 * cpu plugin: Fixed the Solaris code.

315 they're given in numerically form.
317 2007-06-07, Version 4.0.1
318 * iptables plugin: A bug in the configuration routine has been fixed.
319 Setting a comment in the configfile will no longer cause a
322 2007-06-03, Version 4.0.0
323 * collectd: The plugin-infrastructure has been changed to allow for
324 more types of plugins, namely `write' and `log' plugins.
325 * collectd: The read-function has been changed to read many plugins in
326 parallel, using threads. Thus, plugins generally need to use
327 thread-safe functions from now on.
328 * collectd: The '-t' command line options allows to perform syntax tests
329 of the configuration file and exit immediately.
330 * csv plugin: The new `csv' plugin handles output to `comma separated
332 * rrdtool plugin: The new `rrdtool' plugin handles output to
333 RRD-files. Data can be cached to combine multiple updates into one
334 write to increase IO-performance.
335 * network plugin: The new `network' plugin handles IO via the network.
336 It implements a different, much more extensible protocol which can
337 combine many values in one packet, decreasing the number of UDP-
338 packets being sent. It can read from and send to the network and
339 with the appropriate configuration even forward packets to other
341 * unixsock plugin: The new `unixsock' plugin provides an interface to
342 communicate with the daemon while it is running. Right now the
343 commands `GETVAL' and `PUTVAL' are implemented, but more are to
345 * perl plugin: The new `perl' plugin allows you to write extensions
346 for collectd in the scripting-language Perl.
347 * logfile plugin: The new `logfile' plugin writes logmessages to files
349 * syslog plugin: The new `syslog' plugin sends logmessages to the
350 system's syslog daemon.
351 * entropy plugin: The new `entropy' plugin collects the amount of
352 entropy currently being available to the system.
353 * exec plugin: The new `exec' plugin forks child processes and reads
354 back values provided by the forked processes.
355 * iptables plugin: The new `iptables' plugin reads counters from
356 iptables rules. Thanks to Sjoerd van der Berg for contributing this
358 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
359 to Peter Holik for contributing this plugin.
360 * nut plugin: The new `nut' plugin connects the upsd of the `network
361 ups tools' and reads information about the connected UPS.

363 connections) field was added by Florent Monbillard.
364 * collectd-nagios: The new `collectd-nagios' binary queries values
365 from collectd, parses them and exits according to Nagios-standards.
366 * manpages: The manpages have been improved a lot.
368 2007-09-28, Version 3.11.7
369 * wireless plugin: Correct the handling of cards returning signal and

379 were accounted as `zombies'.
381 2007-04-10, Version 3.11.4
382 * dns plugin: Change the order of includes to make the plugin compile
385 2007-03-30, Version 3.11.3
386 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
387 of the unused `COLLECT_KSTAT'.
389 2007-02-11, Version 3.11.2
390 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
391 NULL-pointer may have been passed to `printf' which causes a
392 segfault with some libcs.
394 2007-02-10, Version 3.11.1
395 * df plugin: Some wrong defines have been fixed so the plugin works
397 * dns plugin: The usage of a struct has been fixed to work with
399 * processes plugin: Some missing defines have been added so the plugin
400 compiles cleanly under FreeBSD and presumably other UNIXes.
402 2006-12-22, Version 3.11.0
403 * collectd: The new command line option `-P' makes it easier for
404 distributors to change the location of PID-files.
405 * collectd: The daemon shuts down faster now which makes it easier to
406 write init.d-scripts for it.
407 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
408 caused problems every now and then.
409 * df plugin: New config options allow to ignore certain mountpoints,
410 filesystem types or devices.
411 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
412 and interprets it. It collects traffic as well as qtype, opcode and
414 * email plugin: Sebastian Harl has contributed this plugin which
415 counts received mails in categories (e. g. ham, spam, virus), spam
416 score (as given by SpamAssassin) and check types.
417 * mbmon plugin: Flavio Stanchina has contributed this plugin which
418 uses `mbmon' to gather information from sensors on the motherboard.
419 * processes plugin: Collect detailed statistics for configured
420 processes, that's process and thread count, CPU usage, resident
421 segment size and pagefaults.
422 * multimeter plugin: Peter Holik contributed a new plugin which
424 * sensors plugin: Lubos Stanek has put much effort into improving this
425 plugin, including `extended naming', collection of voltage values
426 and the possibility to ignore certain values.
428 2006-12-21, Version 3.10.4
429 * Max Kellermann has identified a bug in the server routine: When
430 opening a socket fails the daemon will (re)try opening the socket in
431 an endless loop, ultimately leading to a `EMFILE' error.
433 2006-11-04, Version 3.10.3
434 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
435 ntpd's reply was sent in more than one packet, the buffer size was
436 calculated incorrectly, resulting in the reading of uninitialized or
439 2006-11-01, Version 3.10.2
440 * The sample config file has been improved.
441 * Errors in the manpages have been corrected.
442 * The ping-plugin now adds hosts during initialization, not during
443 startup. This speeds up startup when no network connectivity is
444 available. Also, the hosts are being added later when the network is
446 * Improved BSD-support for the df-plugin.
447 * Fixed syntax errors in the swap-plugin for Mac OS X.
448 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
450 * Don't disable the mysql-plugin if connecting to the database fails
451 during initialization. Instead, try again in increasing intervals.
453 2006-07-19, Version 3.10.1
454 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
455 the apcups cannot be reached, unconnected sockets will pile up and
456 eventually lead to `Too many open files' errors.
458 2006-07-09, Version 3.10.0
459 * The `disk' plugin has been ported to Darwin.
460 * The `battery' plugin should work on many Apple computers now.
461 * The `traffic' plugin can now ignore certain interfaces. Also,
462 statistics for sent/received packets and errors have been added.
463 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
464 to Anthony Gialluca for contributing this plugin and providing me
465 with a test environment :)
466 * A plugin for monitoring an NTP instance and the local clock drift
469 2006-06-25, Version 3.9.4
470 * The Solaris code in the `swap' plugin has been changed to reflect
471 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
473 * The debugging system has been fixed to work with the Sun libc.
474 * When built without librrd the variable `operating_mode' could be
475 uninitialized. Thanks to David Elliot for reporting the bug.
477 2006-06-01, Version 3.9.3
478 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
479 operating systems also profit from the changes, but I wasn't able to
481 * Changed the build system to find the netinet-includes under FreeBSD
482 and therefore successfully build the `liboping' library there.
484 2006-05-09, Version 3.9.2
485 * Applied a patch to the `liboping' library. Due to a bug in the
486 sequence checking the `ping' plugin stopped working after
487 approximately 7.6 days.
489 2006-05-09, Version 3.8.5
490 * Applied a patch to the `liboping' library. Due to a bug in the
491 sequence checking the `ping' plugin stopped working after
492 approximately 7.6 days.
494 2006-04-21, Version 3.9.1
495 * Build issues with Solaris and possible other architectures have been
497 * Problems when building the `apache'-plugin without `libcurl' have
499 * A bug in the `ping' plugin has been fixed. Sorry folks.
501 2006-04-02, Version 3.9.0
502 * A plugin to monitor the Apache webserver has been added.
503 <http://httpd.apache.org/>
504 * A plugin to collect statistics about virtual servers using VServer.
505 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
507 * A plugin for wireless LAN cards has been added. It monitors signal
508 strength, link quality and noise ratio..
509 * A plugin for Apple hardware sensors has been added.
510 * An option to compile collectd with different `step' and `heartbeat'
511 settings has been added. The size of RRAs is no longer static but
512 calculated based on the settings for `step' and `width'.
513 * The `ping' plugin can now be configured to use a certain TTL.
514 * A plugin to monitor the hardware sensors of Apple computers has been
516 * The plugins `cpu', `memory', `processes' and `traffic' have been
517 ported to Mach/Darwin (Mac OS X).
518 * The `log mode' has been contributed by Christophe Kalt. It writes
519 the data into text files rather than RRD files.
521 2006-04-09, Version 3.8.4
522 * Applied patch by Vincent Stehlé which improves the disk-name
523 resolution in the `hddtemp' plugin for Linux systems.
525 2006-04-02, Version 3.8.3
526 * Applied a patch by James Byers: The MySQL plugin was not working
527 with MySQL 5.0.2 or later.
529 2006-03-14, Version 3.8.2
530 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
531 the GNU libc, because it points to `/etc/fstab' rather than
534 2006-03-13, Version 3.8.1
535 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
536 * Fixes in the debian `postinst' and `init.d' scripts.
538 2006-03-09, Version 3.8.0
539 * The `ping' plugin no longer uses `libping' but a self written
540 library named `liboping'. With this library it's possible to ping
541 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
543 2006-02-18, Version 3.7.2
544 * A simple bug in the `battery' plugin has been fixed. It should now
545 work with ACPI based batteries as well. Thanks to Sebastian for
547 * Fixing a bug that prevented collectd to be built without librrd.
548 Thanks to Werner Heuser for reporting it.
550 2006-02-04, Version 3.7.1
551 * The new network code has been improved to build with older versions
553 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
554 to Tommie Gannert for this patch.
556 2006-01-30, Version 3.7.0
557 * The `battery' plugin has been added. It collects information about
559 * The MySQL plugin has been improved: It now writes two more RRD
560 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
561 * The `cpufreq' plugin now reads another file since the file it did
562 read so far causes much overhead in the kernel. Also, you need root
563 to read the old file, but not to read the new one.
564 * The `hddtemp' plugin can now be configured to connect to another
565 address and/or port than localhost.
566 * The `df' plugin now prefers `statvfs' over `statfs'.
567 * The network code has been rewritten. collectd now supports unicast
568 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
569 be set in the configfile.
571 2006-01-24, Version 3.6.2
572 * Due to a bug in the configfile handling collectd wouldn't start in
573 client mode. This released fixes this.
575 2006-01-20, Version 3.6.1
576 * Due to a bug in `configure.in' all modules and the binary were
577 linked against `libmysqlclient'. This issue is solved by this
580 2006-01-17, Version 3.6.0
581 * A config file has been added. This allows for loading only specific
583 * A `df' plugin has been added.
584 * A `mysql' plugin has been added.
585 * The `ping' plugin doesn't entirely give up hope when a socket error
586 occurred, but will back of and increase the intervals between tries.
588 2006-01-21, Version 3.5.2
589 * Fixed yet another bug in the signal handling.. Stupid typo..
590 * Improved the ping plugin to not give up on socket errors (backport
593 2005-12-18, Version 3.5.1
594 * The PID-file is now deleted correctly when shutting down the daemon.
595 * SIGINT and SIGTERM are now handled correctly.
597 2005-12-16, Version 3.5.0 (Revision 326)
598 * A bug in the `load' module under Solaris has been fixed.
599 * The `users' module has been contributed by Sebastian Harl. It counts
600 currently logged in users.
601 * The CPU module now works under FreeBSD without the use of
602 `libstatgrab', however SMP support is missing.
603 * The default directories for the RRD files and the PID file now
604 depend on the compile time setting of `localstatedir'.
606 2005-11-15, Version 3.4.0 (Revision 236)
607 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
608 from gentoo's bugzilla for writing the patch.
609 * The build dependency for librrd has been removed. Binaries built
610 without librrd are client-only and will multicast their value as
611 with the `-c' argument.
612 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
613 * The newly introduced `-f' switch prevents daemon initialization
614 (forking, closing standard filehandles, etc.) Thanks to Alvaro
615 Barcellos for this patch.
617 2005-11-04, Version 3.3.0 (Revision 216)
618 * New modules have been added:
619 - `serial', for monitoring traffic on the serial interfaces
620 - `nfs', for graphing NFS procedure calls
621 - `tape', traffic from/to tape devices
622 * The memory.rrd now accepts more than 4Gig of memory.
624 2005-10-26, Version 3.2.0 (Revision 200)
625 * Support for graphing the processes has been added (thanks to Lyonel
627 * If reading from hddtemp fails collectd will increase the time
628 between polls up to one day.
629 * The init.d files have been improved.
630 * Problems with the spec file have been fixed.
632 2005-10-16, Version 3.1.0 (Revision 194)
633 * Added the `setsid' syscall to the startup code.
634 * Support for hddtemp has been added (thanks to Vincent Stehlé)
636 2005-09-30, Version 3.0.0 (Revision 184)
637 * The ability to send/receive data to/from the network (think
638 multicast) has been added.
639 * Modules have been split up into shared libraries can be loaded at
640 runtime. The biggest advantage is that the core program doesn't need
641 to be linked against an external library.
642 * A patch by George Kargiotakis has been applied: It fixes the sensors
643 behaviour then more than one sensor is being queried.
645 2005-09-16, Version 2.1.0 (Revision 172)
646 * A module for swap statistics has been added.
648 2005-09-09, Version 2.0.0 (Revision 135)
649 * Filenames can no longer be configured at program startup. The only
650 options as of this version are the directory and ping hosts.
651 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
652 Soft-IRQ statistics are added to `System'.
653 * Diskstats now collect read and write bytes, not sectors.
654 * Ping statistics can now be collected for more than one host. There
655 is no default any more: If no host is given no host will be pinged.
656 * A self-written patch for libping has been applied so it builds
659 2005-09-01, Version 1.8.1 (Revision 123)
660 * Much improved configure-script: libraries and features may now be
662 * More detailed warnings/error messages when RRD update fails.
664 2005-08-29, Version 1.8.0:
665 * Support for collecting disk statistics under Solaris.
667 2005-08-25, Version 1.7.0:
668 * Support for libstatgrab[1] for load, memory usage and network
669 traffic. CPU- and disk-usage are not (yet) supported, since
670 libstatgrab returns insufficient information. I will contact the
672 * Improved the CPU-initialization code for Solaris. Apparently CPUs
673 aren't necessarily counted linear which is now handled correctly.
674 [1]: http://www.i-scream.org/libstatgrab/
676 2005-08-21, Version 1.6.0:
677 * Basic support for Solaris: System load and cpu-usage can be
678 collected under Solaris, too. Other stats will follow later.
679 * Many fixes in the autoconf-script
680 * Collection/Museum scripts have been added under contrib/museum
681 * collectd may now be started in unprivileged mode, though ping
682 statistics will not work.
684 2005-07-17, Version 1.5.1:
685 * Diskstats-RRDs now use major/minor for naming. Some systems have
686 weird strings as disk-names..
688 2005-07-17, Version 1.5:
689 * A new module, diskstats, has been added. It collects information
690 about the disks and partitions.
692 2005-07-11, Version 1.4.2:
693 * The meminfo module has been changed to work with more platforms
694 and/or kernel versions.
696 2005-07-10, Version 1.4.1: Correct traffic stats
697 * The traffic rrd-file is now created with DS-type `COUNTER' which I
698 forgot to correct when I changed that module.
700 2005-07-09, Version 1.4: More traffic stats
701 * Traffic is now collected for all interfaces that can be found
702 * Temperature-statistics are read from lm-sensors if available
704 2005-07-08, Version 1.3: CPU stats
705 * Collecting CPU statistics now
707 2004-07-12, Version 1.2: Using syslog
708 * collectd is now using the syslog facility to report errors, warnings
710 * The default directory is now /var/db/collectd
712 2004-07-10, Version 1.1: Minor changes
713 * Nothing really useful to say ;)
715 2004-07-09, Version 1.0: Initial Version
716 * The following modules are provided:
