1 2008-04-22, Version 4.3.3
2 * build system: Improved detection of several libraries, especially if
3 they are in non-standard paths.
4 * build system: Portability fixes: Automatically define "_REENTRANT"
5 if the libc expects it.
6 * collectd: Error and warning messages have been improved.
7 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
9 * apache plugin: Allocate new memory when reading a webpage instead of
10 using a buffer of static size.
11 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
13 * hddtemp plugin: Error and warning messages have been improved.
14 * sensors plugin: Fix sensor collection for some chip types.
16 2008-03-29, Version 4.3.2
17 * collectd: Fix configuration of the `FailureMax', `WarningMax', and
18 `Persist' threshold options.
19 * collectd: Fix handling of missing values in the global value cache.
20 * collectd: Improved error messages when parsing the configuration.
21 * sensors plugin: Fix temperature collection with libsensors4.
22 * unixsock plugin: Fix mixed input and output operation on streams.
23 * wireless plugin: Fix reading noise value.
25 2008-03-05, Version 4.3.1
26 * exec plugin: Set supplementary group IDs.
28 + Use `memcpy' when constructing/parsing a package to avoid
29 alignment problems on weird architectures, such as Sparc.
30 + Translate doubles to/from the x86 byte representation to ensure
31 cross-platform compatibility.
32 * ping plugin: Correct the handling of the `TTL' setting.
33 * swap plugin: Reapply a patch for Solaris.
34 * tcpconns plugin: Portability improvements.
36 2008-02-18, Version 4.3.0
37 * collectd: Notifications have been added to the daemon. Notifications
38 are status messages that may be associated with a data instance.
39 * collectd: Threshold checking has been added to the daemon. This
40 means that you can configure threshold values for each data
41 instance. If this threshold is exceeded a notification will be
43 * collectd: The new `FQDNLookup' option tells the daemon to use the
44 full qualified domain name as the hostname, not just the host part
45 es returned by `gethostname(2)'.
46 * collectd: Support for more than one `TypesDB' file has been added.
47 This is useful when one such file is included in a package but one
48 wants to add custom type definitions.
49 * collectd: The `Include' config option has been expanded to handle
50 entire directories and shell wildcards.
51 * collectdmon: The new `collectdmon' binary detects when collectd
52 terminates and automatically restarts it again.
53 * csv plugin: The CSV plugin is now able to store counter values as a
54 rate, using the `StoreRates' configuration option.
55 * exec plugin: Handling of notifications has been added and the
56 ability to pass arguments to the executed programs has been added.
57 * hddtemp plugin: The new `TranslateDevicename' option lets you
58 disable the translation from device names to major-minor-numbers.
59 * logfile plugin: Handling of notifications has been added.
60 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
61 domain name lookups in this plugin.
62 * perl plugin: Many internal changes added support for handling multiple
63 threads making the plugin reasonably usable inside collectd. The API has
64 been extended to support notifications and export global variables to
65 Perl plugins; callbacks now have to be identified by name rather than a
66 pointer to a subroutine. The plugin is no longer experimental.
67 * uuid plugin: The new UUID plugin sets the hostname to an unique
68 identifier for this host. This is meant for setups where each client
69 may migrate to another physical host, possibly going through one or
70 more name changes in the process. Thanks to Richard Jones from
71 Red Hat's Emerging Technology group for this plugin.
72 * libvirt: The new libvirt plugin uses the `libvirt' library to query
73 CPU, disk and network statistics about guest systems on the same
74 physical server. Thanks to Richard Jones from Red Hat's Emerging
75 Technology group for this plugin.
77 2008-04-22, Version 4.2.7
78 * build system: Improved detection of several libraries, especially if
79 they are in non-standard paths.
80 * build system: Portability fixes: Automatically define "_REENTRANT"
81 if the libc expects it.
82 * collectd: Error and warning messages have been improved.
83 * collectd: Check for the BYTE_ORDER and BIG_ENDIAN defines before
85 * apache plugin: Allocate new memory when reading a webpage instead of
86 using a buffer of static size.
87 * exec plugin: Close (almost) all filedescriptors before exec(2)ing
89 * hddtemp plugin: Error and warning messages have been improved.
90 * sensors plugin: Fix sensor collection for some chip types.
92 2008-03-29, Version 4.2.6
93 * collectd: Improved error messages when parsing the configuration.
94 * sensors plugin: Fix temperature collection with libsensors4.
95 * unixsock plugin: Fix mixed input and output operation on streams.
96 * wireless plugin: Fix reading noise value.
98 2008-03-04, Version 4.2.5
99 * apache plugin: Improved initialization and error messages.
100 * exec plugin: Set supplementary group IDs.
102 + Create separate threads for reading from the socket and parsing
103 and dispatching incoming packets. Versions prior to this may have
104 problems in high-load situations, where the socket receive buffers
105 overflows, resulting in gaps in the data.
106 + Use `memcpy' when constructing/parsing a package to avoid
107 alignment problems on weird architectures, such as Sparc.
108 + Translate doubles to/from the x86 byte representation to ensure
109 cross-platform compatibility.
110 * ping plugin: Correct the handling of the `TTL' setting.
111 * rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
112 * swap plugin: Reapply a patch for Solaris.
113 * tcpconns plugin: Portability improvements.
115 2008-01-21, Version 4.2.4
116 * unixsock plugin: A bug in the unixsock plugin caused it not to set
117 the permission on the socket as documented in the manpage. Thanks to
118 Evgeny Chukreev for fixing this issue.
119 * collectd: The documentation has been improved.
121 2007-12-28, Version 4.2.3
122 * sensors plugin: Updated the plugin to build and work with version 3
123 of the libsensors library.
125 2007-12-15, Version 4.2.2
126 * nginx plugin: Incorrect comparison of strings lead to a segfault
127 when using the plugin. Thanks to Saulius Grigaliunas for fixing
129 * logfile plugin: The config option `Timestamp' was handled
130 incorrectly and basically always active. Thanks to Luke Heberling
133 2007-11-08, Version 4.2.1
134 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
136 * snmp plugin: Fix a memory leak.
138 2007-10-27, Version 4.2.0
139 * collectd: The new config option `Include' lets you include other
140 configfiles and thus split up your config into smaller parts. This
141 may be especially interesting for the snmp plugin to keep the data
142 definitions separate from the host definitions.
143 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
144 (number of connections, octets and packets for each service and
145 destination). Thanks to Sebastian Harl for this plugin.
146 * memcached plugin: The new `memcached' plugin connects to a memcached
147 daemon process and collects statistics of this distributed caching
148 system. Thanks to Antony Dovgal for contributing this plugin.
149 * nginx plugin: The new `nginx' plugin reads the status page of an
150 nginx daemon and saves the handled connections and requests.
151 * perl plugin: Many changes, including the added `EnableDebugger'
152 config option which lets you debug your Perl plugins more easily.
153 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
154 be more thread-safe otherwise by locking calls to the library.
155 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
156 correct the values returned by SNMP-agents. If a <data> block is
157 defined as `table' the instance is now optional. The sequence number
158 is used as the type-instance in this case. The new `InstancePrefix'
159 option allows to add arbitrary prefixes to the type-instance.
160 * tcpconns plugin: The new `tcpconns' plugin collects the number of
161 certain TCP connections and what state they're in. This can be used
162 to see how many connections your FTP server has to handle or how
163 many outgoing connections your mailserver has open.
165 2008-01-11, Version 4.1.6
166 * unixsock plugin: A bug in the unixsock plugin caused it not to set
167 the permission on the socket as documented in the manpage. Thanks to
168 Evgeny Chukreev for fixing this issue.
169 * collectd: The documentation has been improved.
171 2007-12-27, Version 4.1.5

175 of the libsensors library.
177 2007-11-08, Version 4.1.4
178 * Build system: Improve detection of the rrd library, especially if
179 it's in a non-standard location.
180 * Build system: A bug when parsing the argument for
181 `--with-libnetsnmp' has been fixed.
182 * collectd: Implement `strerror_r' if the libc doesn't provide it.
183 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
184 a deadlock or delay when shutting down the daemon.
185 * snmp plugin: Fix a memory leak.
187 2007-10-24, Version 4.1.3
188 * collectd: A build issue under Solaris has been resolved by renaming
190 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
191 be more thread-safe otherwise by locking calls to the library.
193 2007-09-28, Version 4.1.2
194 * apcups plugin: Fix reporting of the `load percent' data.
195 * wireless plugin: Correct the handling of cards returning signal and
196 noise quality as percentage.
197 * perl plugin: Fix a possible buffer overflow in get_module_name().
198 * build system: Further improve the detection of libraries.
199 * netlink plugin: Build issues under some older versions of the Linux
200 includes (i. e. Debian Sarge) have been fixed.
201 * snmp plugin: Fix a potential segfault when a host times out. Add
202 support for the `timeticks' type.

205 * Build system: The detection of `libnetlink' has been improved.
206 * collectd: The documentation has been fixed in numerous places.
207 * exec plugin: Setting the group under which to run a program has been
209 * collectd: The `sstrerror' function was improved to work correctly
210 with the broken GNU version of `strerror_r'.
211 * collectd: Write an error message to STDERR when loading of a plugin
213 * apcups plugin: Fix the `types' used to submit the values: They still
214 has an `apcups_' prefix which doesn't work anymore.
215 * rrdtool plugin: Create new RRD-files with the `begin' time set to
216 whatever the client thinks is `now'..
218 2007-09-01, Version 4.1.0
219 * Build system: The build system has been changed to automatically
220 disable all plugins, which are missing dependencies. The dependency
221 checking has been removed from the plugins themselves to remove
223 * Flexible interval: The interval of collected data is now sent along
224 with the data itself over the network, so that the interval-settings
225 of server and clients no longer needs to match.
226 * netlink plugin: The new `netlink' plugin connects to the Linux
227 kernel using a netlink socket and uses it to query information about
228 interfaces, qdiscs and classes.
229 * rrdtool plugin: The cache is now dumped to disk in an extra thread
230 to not block data collection.
231 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
232 network devices, such as switches, routers, thermometers, rack
233 monitoring servers, etc. The collectd-snmp(5) manpage documents this
235 * unixsock plugin: Added the `LISTVAL' command.
236 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
237 of music played with xmms.
239 2007-09-28, Version 4.0.9
240 * apcups plugin: Fix reporting of the `load percent' data.
241 * wireless plugin: Correct the handling of cards returning signal and
242 noise quality as percentage.
243 * perl plugin: Fix a possible buffer overflow in get_module_name().
245 2007-09-12, Version 4.0.8
246 * collectd: The `sstrerror' function was improved to work correctly
247 with the broken GNU version of `strerror_r'.
248 * collectd: Write an error message to STDERR when loading of a plugin
250 * apcups plugin: Fix the `types' used to submit the values: They still
251 has an `apcups_' prefix which doesn't work anymore.
252 * rrdtool plugin: Create new RRD-files with the `begin' time set to
253 whatever the client thinks is `now'..
255 2007-08-26, Version 4.0.7
256 * documentation: Some typos have been fixed and some information has
258 * build system: Many fixes for detecting libraries in unusual places,
259 such as on RedHat systems. The affected libraries are `libcurl',
260 `libmysql', and `libupsclient'.
261 * network plugin: Allow the `Port' option to be specified as a number
262 (i. e. without quotes).
263 * nut plugin: A fix allows linking the nut plugin against
264 libupsclient, version >= 2.2.0.
265 * processes plugin: Fix a potential segmentation fault.
267 2007-07-30, Version 4.0.6
268 * sensors plugin: Fix the ignorelist functionality: Only the `type
269 instance' was used to match against the list, but the documentation
270 told otherwise. This release fixes the code, so it complies with the
272 * syslog plugin: Call `openlog' right when the plugin is loaded, so
273 configuration messages will end up in the logging facility.
274 * conrtib/fedora: The contributed specfile for Fedora has been
277 2007-07-05, Version 4.0.5
278 * Portability: More fixes for OpenBSD have been included.
280 2007-06-24, Version 4.0.4
281 * cpu plugin: Fixed the Solaris code.
282 * dns plugin: Fixed a build issue for OpenBSD.
283 * interface plugin: Fixed the Solaris code.
284 * load plugin: Fixed the alternative `/proc' Linux code.

297 they're given in numerically form.
299 2007-06-07, Version 4.0.1
300 * iptables plugin: A bug in the configuration routine has been fixed.
301 Setting a comment in the configfile will no longer cause a
304 2007-06-03, Version 4.0.0
305 * collectd: The plugin-infrastructure has been changed to allow for
306 more types of plugins, namely `write' and `log' plugins.
307 * collectd: The read-function has been changed to read many plugins in
308 parallel, using threads. Thus, plugins generally need to use
309 thread-safe functions from now on.
310 * collectd: The '-t' command line options allows to perform syntax tests
311 of the configuration file and exit immediately.
312 * csv plugin: The new `csv' plugin handles output to `comma separated
314 * rrdtool plugin: The new `rrdtool' plugin handles output to
315 RRD-files. Data can be cached to combine multiple updates into one
316 write to increase IO-performance.
317 * network plugin: The new `network' plugin handles IO via the network.
318 It implements a different, much more extensible protocol which can
319 combine many values in one packet, decreasing the number of UDP-
320 packets being sent. It can read from and send to the network and
321 with the appropriate configuration even forward packets to other
323 * unixsock plugin: The new `unixsock' plugin provides an interface to
324 communicate with the daemon while it is running. Right now the
325 commands `GETVAL' and `PUTVAL' are implemented, but more are to
327 * perl plugin: The new `perl' plugin allows you to write extensions
328 for collectd in the scripting-language Perl.
329 * logfile plugin: The new `logfile' plugin writes logmessages to files
331 * syslog plugin: The new `syslog' plugin sends logmessages to the
332 system's syslog daemon.
333 * entropy plugin: The new `entropy' plugin collects the amount of
334 entropy currently being available to the system.
335 * exec plugin: The new `exec' plugin forks child processes and reads
336 back values provided by the forked processes.
337 * iptables plugin: The new `iptables' plugin reads counters from
338 iptables rules. Thanks to Sjoerd van der Berg for contributing this
340 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
341 to Peter Holik for contributing this plugin.
342 * nut plugin: The new `nut' plugin connects the upsd of the `network
343 ups tools' and reads information about the connected UPS.
344 * apache plugin: Support for lighttpd's `BusyServers' (aka.
345 connections) field was added by Florent Monbillard.
346 * collectd-nagios: The new `collectd-nagios' binary queries values
347 from collectd, parses them and exits according to Nagios-standards.
348 * manpages: The manpages have been improved a lot.
350 2007-09-28, Version 3.11.7
351 * wireless plugin: Correct the handling of cards returning signal and

360 * processes plugin: Fix a bug when run under Linux 2.4. All processes
361 were accounted as `zombies'.
363 2007-04-10, Version 3.11.4
364 * dns plugin: Change the order of includes to make the plugin compile
367 2007-03-30, Version 3.11.3
368 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
369 of the unused `COLLECT_KSTAT'.
371 2007-02-11, Version 3.11.2
372 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
373 NULL-pointer may have been passed to `printf' which causes a
374 segfault with some libcs.
376 2007-02-10, Version 3.11.1
377 * df plugin: Some wrong defines have been fixed so the plugin works
379 * dns plugin: The usage of a struct has been fixed to work with
381 * processes plugin: Some missing defines have been added so the plugin
382 compiles cleanly under FreeBSD and presumably other UNIXes.
384 2006-12-22, Version 3.11.0
385 * collectd: The new command line option `-P' makes it easier for
386 distributors to change the location of PID-files.
387 * collectd: The daemon shuts down faster now which makes it easier to
388 write init.d-scripts for it.
389 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
390 caused problems every now and then.
391 * df plugin: New config options allow to ignore certain mountpoints,
392 filesystem types or devices.
393 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
394 and interprets it. It collects traffic as well as qtype, opcode and
396 * email plugin: Sebastian Harl has contributed this plugin which
397 counts received mails in categories (e. g. ham, spam, virus), spam
398 score (as given by SpamAssassin) and check types.
399 * mbmon plugin: Flavio Stanchina has contributed this plugin which
400 uses `mbmon' to gather information from sensors on the motherboard.
401 * processes plugin: Collect detailed statistics for configured
402 processes, that's process and thread count, CPU usage, resident
403 segment size and pagefaults.
404 * multimeter plugin: Peter Holik contributed a new plugin which
406 * sensors plugin: Lubos Stanek has put much effort into improving this
407 plugin, including `extended naming', collection of voltage values
408 and the possibility to ignore certain values.
410 2006-12-21, Version 3.10.4
411 * Max Kellermann has identified a bug in the server routine: When
412 opening a socket fails the daemon will (re)try opening the socket in
413 an endless loop, ultimately leading to a `EMFILE' error.
415 2006-11-04, Version 3.10.3
416 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
417 ntpd's reply was sent in more than one packet, the buffer size was
418 calculated incorrectly, resulting in the reading of uninitialized or
421 2006-11-01, Version 3.10.2
422 * The sample config file has been improved.
423 * Errors in the manpages have been corrected.
424 * The ping-plugin now adds hosts during initialization, not during
425 startup. This speeds up startup when no network connectivity is
426 available. Also, the hosts are being added later when the network is
428 * Improved BSD-support for the df-plugin.
429 * Fixed syntax errors in the swap-plugin for Mac OS X.
430 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
432 * Don't disable the mysql-plugin if connecting to the database fails
433 during initialization. Instead, try again in increasing intervals.
435 2006-07-19, Version 3.10.1
436 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
437 the apcups cannot be reached, unconnected sockets will pile up and
438 eventually lead to `Too many open files' errors.
440 2006-07-09, Version 3.10.0
441 * The `disk' plugin has been ported to Darwin.
442 * The `battery' plugin should work on many Apple computers now.
443 * The `traffic' plugin can now ignore certain interfaces. Also,
444 statistics for sent/received packets and errors have been added.
445 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
446 to Anthony Gialluca for contributing this plugin and providing me
447 with a test environment :)
448 * A plugin for monitoring an NTP instance and the local clock drift
451 2006-06-25, Version 3.9.4
452 * The Solaris code in the `swap' plugin has been changed to reflect
453 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
455 * The debugging system has been fixed to work with the Sun libc.
456 * When built without librrd the variable `operating_mode' could be
457 uninitialized. Thanks to David Elliot for reporting the bug.
459 2006-06-01, Version 3.9.3
460 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
461 operating systems also profit from the changes, but I wasn't able to
463 * Changed the build system to find the netinet-includes under FreeBSD
464 and therefore successfully build the `liboping' library there.
466 2006-05-09, Version 3.9.2
467 * Applied a patch to the `liboping' library. Due to a bug in the
468 sequence checking the `ping' plugin stopped working after
469 approximately 7.6 days.
471 2006-05-09, Version 3.8.5
472 * Applied a patch to the `liboping' library. Due to a bug in the
473 sequence checking the `ping' plugin stopped working after
474 approximately 7.6 days.
476 2006-04-21, Version 3.9.1
477 * Build issues with Solaris and possible other architectures have been
479 * Problems when building the `apache'-plugin without `libcurl' have
481 * A bug in the `ping' plugin has been fixed. Sorry folks.
483 2006-04-02, Version 3.9.0
484 * A plugin to monitor the Apache webserver has been added.
485 <http://httpd.apache.org/>
486 * A plugin to collect statistics about virtual servers using VServer.
487 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
489 * A plugin for wireless LAN cards has been added. It monitors signal
490 strength, link quality and noise ratio..
491 * A plugin for Apple hardware sensors has been added.
492 * An option to compile collectd with different `step' and `heartbeat'
493 settings has been added. The size of RRAs is no longer static but
494 calculated based on the settings for `step' and `width'.
495 * The `ping' plugin can now be configured to use a certain TTL.
496 * A plugin to monitor the hardware sensors of Apple computers has been
498 * The plugins `cpu', `memory', `processes' and `traffic' have been
499 ported to Mach/Darwin (Mac OS X).
500 * The `log mode' has been contributed by Christophe Kalt. It writes
501 the data into text files rather than RRD files.
503 2006-04-09, Version 3.8.4
504 * Applied patch by Vincent Stehlé which improves the disk-name
505 resolution in the `hddtemp' plugin for Linux systems.
507 2006-04-02, Version 3.8.3
508 * Applied a patch by James Byers: The MySQL plugin was not working
509 with MySQL 5.0.2 or later.
511 2006-03-14, Version 3.8.2
512 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
513 the GNU libc, because it points to `/etc/fstab' rather than
516 2006-03-13, Version 3.8.1
517 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
518 * Fixes in the debian `postinst' and `init.d' scripts.
520 2006-03-09, Version 3.8.0
521 * The `ping' plugin no longer uses `libping' but a self written
522 library named `liboping'. With this library it's possible to ping
523 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
525 2006-02-18, Version 3.7.2
526 * A simple bug in the `battery' plugin has been fixed. It should now
527 work with ACPI based batteries as well. Thanks to Sebastian for
529 * Fixing a bug that prevented collectd to be built without librrd.
530 Thanks to Werner Heuser for reporting it.
532 2006-02-04, Version 3.7.1
533 * The new network code has been improved to build with older versions
535 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
536 to Tommie Gannert for this patch.
538 2006-01-30, Version 3.7.0
539 * The `battery' plugin has been added. It collects information about
541 * The MySQL plugin has been improved: It now writes two more RRD
542 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
543 * The `cpufreq' plugin now reads another file since the file it did
544 read so far causes much overhead in the kernel. Also, you need root
545 to read the old file, but not to read the new one.
546 * The `hddtemp' plugin can now be configured to connect to another
547 address and/or port than localhost.
548 * The `df' plugin now prefers `statvfs' over `statfs'.
549 * The network code has been rewritten. collectd now supports unicast
550 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
551 be set in the configfile.
553 2006-01-24, Version 3.6.2
554 * Due to a bug in the configfile handling collectd wouldn't start in
555 client mode. This released fixes this.
557 2006-01-20, Version 3.6.1
558 * Due to a bug in `configure.in' all modules and the binary were
559 linked against `libmysqlclient'. This issue is solved by this
562 2006-01-17, Version 3.6.0
563 * A config file has been added. This allows for loading only specific
565 * A `df' plugin has been added.
566 * A `mysql' plugin has been added.
567 * The `ping' plugin doesn't entirely give up hope when a socket error
568 occurred, but will back of and increase the intervals between tries.
570 2006-01-21, Version 3.5.2
571 * Fixed yet another bug in the signal handling.. Stupid typo..
572 * Improved the ping plugin to not give up on socket errors (backport
575 2005-12-18, Version 3.5.1
576 * The PID-file is now deleted correctly when shutting down the daemon.
577 * SIGINT and SIGTERM are now handled correctly.
579 2005-12-16, Version 3.5.0 (Revision 326)
580 * A bug in the `load' module under Solaris has been fixed.
581 * The `users' module has been contributed by Sebastian Harl. It counts
582 currently logged in users.
583 * The CPU module now works under FreeBSD without the use of
584 `libstatgrab', however SMP support is missing.
585 * The default directories for the RRD files and the PID file now
586 depend on the compile time setting of `localstatedir'.
588 2005-11-15, Version 3.4.0 (Revision 236)
589 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
590 from gentoo's bugzilla for writing the patch.
591 * The build dependency for librrd has been removed. Binaries built
592 without librrd are client-only and will multicast their value as
593 with the `-c' argument.
594 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
595 * The newly introduced `-f' switch prevents daemon initialization
596 (forking, closing standard filehandles, etc.) Thanks to Alvaro
597 Barcellos for this patch.
599 2005-11-04, Version 3.3.0 (Revision 216)
600 * New modules have been added:
601 - `serial', for monitoring traffic on the serial interfaces
602 - `nfs', for graphing NFS procedure calls
603 - `tape', traffic from/to tape devices
604 * The memory.rrd now accepts more than 4Gig of memory.
606 2005-10-26, Version 3.2.0 (Revision 200)
607 * Support for graphing the processes has been added (thanks to Lyonel
609 * If reading from hddtemp fails collectd will increase the time
610 between polls up to one day.
611 * The init.d files have been improved.
612 * Problems with the spec file have been fixed.
614 2005-10-16, Version 3.1.0 (Revision 194)
615 * Added the `setsid' syscall to the startup code.
616 * Support for hddtemp has been added (thanks to Vincent Stehlé)
618 2005-09-30, Version 3.0.0 (Revision 184)
619 * The ability to send/receive data to/from the network (think
620 multicast) has been added.
621 * Modules have been split up into shared libraries can be loaded at
622 runtime. The biggest advantage is that the core program doesn't need
623 to be linked against an external library.
624 * A patch by George Kargiotakis has been applied: It fixes the sensors
625 behaviour then more than one sensor is being queried.
627 2005-09-16, Version 2.1.0 (Revision 172)
628 * A module for swap statistics has been added.
630 2005-09-09, Version 2.0.0 (Revision 135)
631 * Filenames can no longer be configured at program startup. The only
632 options as of this version are the directory and ping hosts.
633 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
634 Soft-IRQ statistics are added to `System'.
635 * Diskstats now collect read and write bytes, not sectors.
636 * Ping statistics can now be collected for more than one host. There
637 is no default any more: If no host is given no host will be pinged.
638 * A self-written patch for libping has been applied so it builds
641 2005-09-01, Version 1.8.1 (Revision 123)
642 * Much improved configure-script: libraries and features may now be
644 * More detailed warnings/error messages when RRD update fails.
646 2005-08-29, Version 1.8.0:
647 * Support for collecting disk statistics under Solaris.
649 2005-08-25, Version 1.7.0:
650 * Support for libstatgrab[1] for load, memory usage and network
651 traffic. CPU- and disk-usage are not (yet) supported, since
652 libstatgrab returns insufficient information. I will contact the
654 * Improved the CPU-initialization code for Solaris. Apparently CPUs
655 aren't necessarily counted linear which is now handled correctly.
656 [1]: http://www.i-scream.org/libstatgrab/
658 2005-08-21, Version 1.6.0:
659 * Basic support for Solaris: System load and cpu-usage can be
660 collected under Solaris, too. Other stats will follow later.
661 * Many fixes in the autoconf-script
662 * Collection/Museum scripts have been added under contrib/museum
663 * collectd may now be started in unprivileged mode, though ping
664 statistics will not work.
666 2005-07-17, Version 1.5.1:
667 * Diskstats-RRDs now use major/minor for naming. Some systems have
668 weird strings as disk-names..
670 2005-07-17, Version 1.5:
671 * A new module, diskstats, has been added. It collects information
672 about the disks and partitions.
674 2005-07-11, Version 1.4.2:
675 * The meminfo module has been changed to work with more platforms
676 and/or kernel versions.
678 2005-07-10, Version 1.4.1: Correct traffic stats
679 * The traffic rrd-file is now created with DS-type `COUNTER' which I
680 forgot to correct when I changed that module.
682 2005-07-09, Version 1.4: More traffic stats
683 * Traffic is now collected for all interfaces that can be found
684 * Temperature-statistics are read from lm-sensors if available
686 2005-07-08, Version 1.3: CPU stats
687 * Collecting CPU statistics now
689 2004-07-12, Version 1.2: Using syslog
690 * collectd is now using the syslog facility to report errors, warnings
692 * The default directory is now /var/db/collectd
694 2004-07-10, Version 1.1: Minor changes
695 * Nothing really useful to say ;)
697 2004-07-09, Version 1.0: Initial Version
698 * The following modules are provided:
