1 2008-02-18, Version 4.3.0
2 * collectd: Notifications have been added to the daemon. Notifications
3 are status messages that may be associated with a data instance.
4 * collectd: Threshold checking has been added to the daemon. This
5 means that you can configure threshold values for each data
6 instance. If this threshold is exceeded a notification will be
8 * collectd: The new `FQDNLookup' option tells the daemon to use the
9 full qualified domain name as the hostname, not just the host part
10 es returned by `gethostname(2)'.
11 * collectd: Support for more than one `TypesDB' file has been added.
12 This is useful when one such file is included in a package but one
13 wants to add custom type definitions.
14 * collectd: The `Include' config option has been expanded to handle
15 entire directories and shell wildcards.
16 * collectdmon: The new `collectdmon' binary detects when collectd
17 terminates and automatically restarts it again.
18 * csv plugin: The CSV plugin is now able to store counter values as a
19 rate, using the `StoreRates' configuration option.
20 * exec plugin: Handling of notifications has been added and a special
21 executable type for Nagios plugins has been implemented. Also, the
22 ability to pass arguments to the executed programs has been added.
23 * hddtemp plugin: The new `TranslateDevicename' option lets you
24 disable the translation from device names to major-minor-numbers.
25 * logfile plugin: Handling of notifications has been added.
26 * ntpd plugin: The new `ReverseLookups' can be used to disable reverse
27 domain name lookups in this plugin.
28 * perl plugin: Many internal changes added support for handling multiple
29 threads making the plugin reasonably usable inside collectd. The API has
30 been extended to support notifications and export global variables to
31 Perl plugins; callbacks now have to be identified by name rather than a
32 pointer to a subroutine. The plugin is no longer experimental.
33 * uuid plugin: The new UUID plugin sets the hostname to an unique
34 identifier for this host. This is meant for setups where each client
35 may migrate to another physical host, possibly going through one or
36 more name changes in the process. Thanks to Richard Jones from
37 Red Hat's Emerging Technology group for this plugin.
38 * libvirt: The new libvirt plugin uses the `libvirt' library to query
39 CPU, disk and network statistics about guest systems on the same
40 physical server. Thanks to Richard Jones from Red Hat's Emerging
41 Technology group for this plugin.
43 2008-01-21, Version 4.2.4
44 * unixsock plugin: A bug in the unixsock plugin caused it not to set
45 the permission on the socket as documented in the manpage. Thanks to
46 Evgeny Chukreev for fixing this issue.
47 * collectd: The documentation has been improved.
49 2007-12-28, Version 4.2.3
50 * sensors plugin: Updated the plugin to build and work with version 3
51 of the libsensors library.
53 2007-12-15, Version 4.2.2
54 * nginx plugin: Incorrect comparison of strings lead to a segfault
55 when using the plugin. Thanks to Saulius Grigaliunas for fixing
57 * logfile plugin: The config option `Timestamp' was handled
58 incorrectly and basically always active. Thanks to Luke Heberling
61 2007-11-08, Version 4.2.1
62 * tcpconns plugin: Don't complain about a missing file if IPv6 is not
64 * snmp plugin: Fix a memory leak.
66 2007-10-27, Version 4.2.0
67 * collectd: The new config option `Include' lets you include other
68 configfiles and thus split up your config into smaller parts. This
69 may be especially interesting for the snmp plugin to keep the data
70 definitions separate from the host definitions.
71 * ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
72 (number of connections, octets and packets for each service and
73 destination). Thanks to Sebastian Harl for this plugin.
74 * memcached plugin: The new `memcached' plugin connects to a memcached
75 daemon process and collects statistics of this distributed caching
76 system. Thanks to Antony Dovgal for contributing this plugin.
77 * nginx plugin: The new `nginx' plugin reads the status page of an
78 nginx daemon and saves the handled connections and requests.
79 * perl plugin: Many changes, including the added `EnableDebugger'
80 config option which lets you debug your Perl plugins more easily.
81 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
82 be more thread-safe otherwise by locking calls to the library.
83 * snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
84 correct the values returned by SNMP-agents. If a <data> block is
85 defined as `table' the instance is now optional. The sequence number
86 is used as the type-instance in this case. The new `InstancePrefix'
87 option allows to add arbitrary prefixes to the type-instance.
88 * tcpconns plugin: The new `tcpconns' plugin collects the number of
89 certain TCP connections and what state they're in. This can be used
90 to see how many connections your FTP server has to handle or how
91 many outgoing connections your mailserver has open.
93 2008-01-11, Version 4.1.6
94 * unixsock plugin: A bug in the unixsock plugin caused it not to set
95 the permission on the socket as documented in the manpage. Thanks to
96 Evgeny Chukreev for fixing this issue.
97 * collectd: The documentation has been improved.
99 2007-12-27, Version 4.1.5
100 * rrdtool plugin: Fix a memory leak that only occured in very-low-

103 of the libsensors library.
105 2007-11-08, Version 4.1.4
106 * Build system: Improve detection of the rrd library, especially if
107 it's in a non-standard location.
108 * Build system: A bug when parsing the argument for
109 `--with-libnetsnmp' has been fixed.
110 * collectd: Implement `strerror_r' if the libc doesn't provide it.
111 * rrdtool plugin: Fix a bug in the shutdown sequence that might cause
112 a deadlock or delay when shutting down the daemon.
113 * snmp plugin: Fix a memory leak.
115 2007-10-24, Version 4.1.3
116 * collectd: A build issue under Solaris has been resolved by renaming
118 * rrdtool plugin: Use the thread-safe RRD-library if available. Try to
119 be more thread-safe otherwise by locking calls to the library.
121 2007-09-28, Version 4.1.2
122 * apcups plugin: Fix reporting of the `load percent' data.
123 * wireless plugin: Correct the handling of cards returning signal and
124 noise quality as percentage.
125 * perl plugin: Fix a possible buffer overflow in get_module_name().
126 * build system: Further improve the detection of libraries.
127 * netlink plugin: Build issues under some older versions of the Linux
128 includes (i. e. Debian Sarge) have been fixed.
129 * snmp plugin: Fix a potential segfault when a host times out. Add
130 support for the `timeticks' type.

133 * Build system: The detection of `libnetlink' has been improved.
134 * collectd: The documentation has been fixed in numerous places.
135 * exec plugin: Setting the group under which to run a program has been
137 * collectd: The `sstrerror' function was improved to work correctly
138 with the broken GNU version of `strerror_r'.
139 * collectd: Write an error message to STDERR when loading of a plugin
141 * apcups plugin: Fix the `types' used to submit the values: They still
142 has an `apcups_' prefix which doesn't work anymore.
143 * rrdtool plugin: Create new RRD-files with the `begin' time set to
144 whatever the client thinks is `now'..
146 2007-09-01, Version 4.1.0
147 * Build system: The build system has been changed to automatically
148 disable all plugins, which are missing dependencies. The dependency
149 checking has been removed from the plugins themselves to remove
151 * Flexible interval: The interval of collected data is now sent along
152 with the data itself over the network, so that the interval-settings
153 of server and clients no longer needs to match.
154 * netlink plugin: The new `netlink' plugin connects to the Linux
155 kernel using a netlink socket and uses it to query information about
156 interfaces, qdiscs and classes.
157 * rrdtool plugin: The cache is now dumped to disk in an extra thread
158 to not block data collection.
159 * snmp plugin: The new `snmp' plugin can read values from SNMP enabled
160 network devices, such as switches, routers, thermometers, rack
161 monitoring servers, etc. The collectd-snmp(5) manpage documents this
163 * unixsock plugin: Added the `LISTVAL' command.
164 * xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
165 of music played with xmms.
167 2007-09-28, Version 4.0.9
168 * apcups plugin: Fix reporting of the `load percent' data.
169 * wireless plugin: Correct the handling of cards returning signal and
170 noise quality as percentage.
171 * perl plugin: Fix a possible buffer overflow in get_module_name().
173 2007-09-12, Version 4.0.8
174 * collectd: The `sstrerror' function was improved to work correctly
175 with the broken GNU version of `strerror_r'.
176 * collectd: Write an error message to STDERR when loading of a plugin
178 * apcups plugin: Fix the `types' used to submit the values: They still
179 has an `apcups_' prefix which doesn't work anymore.
180 * rrdtool plugin: Create new RRD-files with the `begin' time set to
181 whatever the client thinks is `now'..
183 2007-08-26, Version 4.0.7
184 * documentation: Some typos have been fixed and some information has
186 * build system: Many fixes for detecting libraries in unusual places,
187 such as on RedHat systems. The affected libraries are `libcurl',
188 `libmysql', and `libupsclient'.
189 * network plugin: Allow the `Port' option to be specified as a number
190 (i. e. without quotes).
191 * nut plugin: A fix allows linking the nut plugin against
192 libupsclient, version >= 2.2.0.
193 * processes plugin: Fix a potential segmentation fault.
195 2007-07-30, Version 4.0.6
196 * sensors plugin: Fix the ignorelist functionality: Only the `type
197 instance' was used to match against the list, but the documentation
198 told otherwise. This release fixes the code, so it complies with the
200 * syslog plugin: Call `openlog' right when the plugin is loaded, so
201 configuration messages will end up in the logging facility.
202 * conrtib/fedora: The contributed specfile for Fedora has been
205 2007-07-05, Version 4.0.5
206 * Portability: More fixes for OpenBSD have been included.
208 2007-06-24, Version 4.0.4
209 * cpu plugin: Fixed the Solaris code.
210 * dns plugin: Fixed a build issue for OpenBSD.
211 * interface plugin: Fixed the Solaris code.
212 * load plugin: Fixed the alternative `/proc' Linux code.
213 * memory plugin: Fixed the Solaris code.
214 * oconfig: Don't require `-lfl' anymore.
216 2007-06-19, Version 4.0.3
217 * cpu plugin: Fix the Darwin / Mac OS X code.
218 * ping plugin: Use the return value of `getpid', not its address.
219 * csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
220 initialized correctly.
221 * configure: Added `--with-nan-emulation' to aid cross compilation.
223 2007-06-12, Version 4.0.2

225 they're given in numerically form.
227 2007-06-07, Version 4.0.1
228 * iptables plugin: A bug in the configuration routine has been fixed.
229 Setting a comment in the configfile will no longer cause a
232 2007-06-03, Version 4.0.0
233 * collectd: The plugin-infrastructure has been changed to allow for
234 more types of plugins, namely `write' and `log' plugins.
235 * collectd: The read-function has been changed to read many plugins in
236 parallel, using threads. Thus, plugins generally need to use
237 thread-safe functions from now on.
238 * collectd: The '-t' command line options allows to perform syntax tests
239 of the configuration file and exit immediately.
240 * csv plugin: The new `csv' plugin handles output to `comma separated
242 * rrdtool plugin: The new `rrdtool' plugin handles output to
243 RRD-files. Data can be cached to combine multiple updates into one
244 write to increase IO-performance.
245 * network plugin: The new `network' plugin handles IO via the network.
246 It implements a different, much more extensible protocol which can
247 combine many values in one packet, decreasing the number of UDP-
248 packets being sent. It can read from and send to the network and
249 with the appropriate configuration even forward packets to other
251 * unixsock plugin: The new `unixsock' plugin provides an interface to
252 communicate with the daemon while it is running. Right now the
253 commands `GETVAL' and `PUTVAL' are implemented, but more are to
255 * perl plugin: The new `perl' plugin allows you to write extensions
256 for collectd in the scripting-language Perl.
257 * logfile plugin: The new `logfile' plugin writes logmessages to files
259 * syslog plugin: The new `syslog' plugin sends logmessages to the
260 system's syslog daemon.
261 * entropy plugin: The new `entropy' plugin collects the amount of
262 entropy currently being available to the system.
263 * exec plugin: The new `exec' plugin forks child processes and reads
264 back values provided by the forked processes.
265 * iptables plugin: The new `iptables' plugin reads counters from
266 iptables rules. Thanks to Sjoerd van der Berg for contributing this
268 * irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
269 to Peter Holik for contributing this plugin.
270 * nut plugin: The new `nut' plugin connects the upsd of the `network
271 ups tools' and reads information about the connected UPS.
272 * apache plugin: Support for lighttpd's `BusyServers' (aka.
273 connections) field was added by Florent Monbillard.
274 * collectd-nagios: The new `collectd-nagios' binary queries values
275 from collectd, parses them and exits according to Nagios-standards.
276 * manpages: The manpages have been improved a lot.
278 2007-09-28, Version 3.11.7
279 * wireless plugin: Correct the handling of cards returning signal and
280 noise quality as percentage.
282 2007-08-31, Version 3.11.6

286 * configure: Added `AC_SYS_LARGEFILE' for LFS.
287 * ntpd plugin: Fix a potential buffer overflow.
288 * processes plugin: Fix a bug when run under Linux 2.4. All processes
289 were accounted as `zombies'.
291 2007-04-10, Version 3.11.4
292 * dns plugin: Change the order of includes to make the plugin compile
295 2007-03-30, Version 3.11.3
296 * configure: Have the configure-script define `HAVE_LIBKSTAT' instead
297 of the unused `COLLECT_KSTAT'.
299 2007-02-11, Version 3.11.2
300 * plugin: Catch NULL-pointer and try to fix them. Otherwise the
301 NULL-pointer may have been passed to `printf' which causes a
302 segfault with some libcs.
304 2007-02-10, Version 3.11.1
305 * df plugin: Some wrong defines have been fixed so the plugin works
307 * dns plugin: The usage of a struct has been fixed to work with
309 * processes plugin: Some missing defines have been added so the plugin
310 compiles cleanly under FreeBSD and presumably other UNIXes.
312 2006-12-22, Version 3.11.0
313 * collectd: The new command line option `-P' makes it easier for
314 distributors to change the location of PID-files.
315 * collectd: The daemon shuts down faster now which makes it easier to
316 write init.d-scripts for it.
317 * apache plugin: Increase the buffersize to 16k, because the 4k buffer
318 caused problems every now and then.
319 * df plugin: New config options allow to ignore certain mountpoints,
320 filesystem types or devices.
321 * dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
322 and interprets it. It collects traffic as well as qtype, opcode and
324 * email plugin: Sebastian Harl has contributed this plugin which
325 counts received mails in categories (e. g. ham, spam, virus), spam
326 score (as given by SpamAssassin) and check types.
327 * mbmon plugin: Flavio Stanchina has contributed this plugin which
328 uses `mbmon' to gather information from sensors on the motherboard.
329 * processes plugin: Collect detailed statistics for configured
330 processes, that's process and thread count, CPU usage, resident
331 segment size and pagefaults.
332 * multimeter plugin: Peter Holik contributed a new plugin which
334 * sensors plugin: Lubos Stanek has put much effort into improving this
335 plugin, including `extended naming', collection of voltage values
336 and the possibility to ignore certain values.
338 2006-12-21, Version 3.10.4
339 * Max Kellermann has identified a bug in the server routine: When
340 opening a socket fails the daemon will (re)try opening the socket in
341 an endless loop, ultimately leading to a `EMFILE' error.
343 2006-11-04, Version 3.10.3
344 * Lubos Stanek has identified a bug in the ntpd-plugin: When the
345 ntpd's reply was sent in more than one packet, the buffer size was
346 calculated incorrectly, resulting in the reading of uninitialized or
349 2006-11-01, Version 3.10.2
350 * The sample config file has been improved.
351 * Errors in the manpages have been corrected.
352 * The ping-plugin now adds hosts during initialization, not during
353 startup. This speeds up startup when no network connectivity is
354 available. Also, the hosts are being added later when the network is
356 * Improved BSD-support for the df-plugin.
357 * Fixed syntax errors in the swap-plugin for Mac OS X.
358 * Fix a wrong structure being passed to `getnameinfo' in the ntpd-
360 * Don't disable the mysql-plugin if connecting to the database fails
361 during initialization. Instead, try again in increasing intervals.
363 2006-07-19, Version 3.10.1
364 * A bug in the apcups plugin was fixed: Is the plugin is loaded, but
365 the apcups cannot be reached, unconnected sockets will pile up and
366 eventually lead to `Too many open files' errors.
368 2006-07-09, Version 3.10.0
369 * The `disk' plugin has been ported to Darwin.
370 * The `battery' plugin should work on many Apple computers now.
371 * The `traffic' plugin can now ignore certain interfaces. Also,
372 statistics for sent/received packets and errors have been added.
373 * A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
374 to Anthony Gialluca for contributing this plugin and providing me
375 with a test environment :)
376 * A plugin for monitoring an NTP instance and the local clock drift
379 2006-06-25, Version 3.9.4
380 * The Solaris code in the `swap' plugin has been changed to reflect
381 the numbers returned by `swap -s'. Thanks to Christophe Kalt for
383 * The debugging system has been fixed to work with the Sun libc.
384 * When built without librrd the variable `operating_mode' could be
385 uninitialized. Thanks to David Elliot for reporting the bug.
387 2006-06-01, Version 3.9.3
388 * Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
389 operating systems also profit from the changes, but I wasn't able to
391 * Changed the build system to find the netinet-includes under FreeBSD
392 and therefore successfully build the `liboping' library there.
394 2006-05-09, Version 3.9.2
395 * Applied a patch to the `liboping' library. Due to a bug in the
396 sequence checking the `ping' plugin stopped working after
397 approximately 7.6 days.
399 2006-05-09, Version 3.8.5
400 * Applied a patch to the `liboping' library. Due to a bug in the
401 sequence checking the `ping' plugin stopped working after
402 approximately 7.6 days.
404 2006-04-21, Version 3.9.1
405 * Build issues with Solaris and possible other architectures have been
407 * Problems when building the `apache'-plugin without `libcurl' have
409 * A bug in the `ping' plugin has been fixed. Sorry folks.
411 2006-04-02, Version 3.9.0
412 * A plugin to monitor the Apache webserver has been added.
413 <http://httpd.apache.org/>
414 * A plugin to collect statistics about virtual servers using VServer.
415 <http://linux-vserver.org/> Thanks to Sebastian Harl for writing
417 * A plugin for wireless LAN cards has been added. It monitors signal
418 strength, link quality and noise ratio..
419 * A plugin for Apple hardware sensors has been added.
420 * An option to compile collectd with different `step' and `heartbeat'
421 settings has been added. The size of RRAs is no longer static but
422 calculated based on the settings for `step' and `width'.
423 * The `ping' plugin can now be configured to use a certain TTL.
424 * A plugin to monitor the hardware sensors of Apple computers has been
426 * The plugins `cpu', `memory', `processes' and `traffic' have been
427 ported to Mach/Darwin (Mac OS X).
428 * The `log mode' has been contributed by Christophe Kalt. It writes
429 the data into text files rather than RRD files.
431 2006-04-09, Version 3.8.4
432 * Applied patch by Vincent Stehlé which improves the disk-name
433 resolution in the `hddtemp' plugin for Linux systems.
435 2006-04-02, Version 3.8.3
436 * Applied a patch by James Byers: The MySQL plugin was not working
437 with MySQL 5.0.2 or later.
439 2006-03-14, Version 3.8.2
440 * `utils_mount.c' has been changed to not use the `MNTTAB' defined by
441 the GNU libc, because it points to `/etc/fstab' rather than
444 2006-03-13, Version 3.8.1
445 * Fixes for building collectd under FreeBSD, Mac OS X and Solaris.
446 * Fixes in the debian `postinst' and `init.d' scripts.
448 2006-03-09, Version 3.8.0
449 * The `ping' plugin no longer uses `libping' but a self written
450 library named `liboping'. With this library it's possible to ping
451 multiple IPv4 and IPv6 addresses and hostnames - in parallel.
453 2006-02-18, Version 3.7.2
454 * A simple bug in the `battery' plugin has been fixed. It should now
455 work with ACPI based batteries as well. Thanks to Sebastian for
457 * Fixing a bug that prevented collectd to be built without librrd.
458 Thanks to Werner Heuser for reporting it.
460 2006-02-04, Version 3.7.1
461 * The new network code has been improved to build with older versions
463 * Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
464 to Tommie Gannert for this patch.
466 2006-01-30, Version 3.7.0
467 * The `battery' plugin has been added. It collects information about
469 * The MySQL plugin has been improved: It now writes two more RRD
470 files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
471 * The `cpufreq' plugin now reads another file since the file it did
472 read so far causes much overhead in the kernel. Also, you need root
473 to read the old file, but not to read the new one.
474 * The `hddtemp' plugin can now be configured to connect to another
475 address and/or port than localhost.
476 * The `df' plugin now prefers `statvfs' over `statfs'.
477 * The network code has been rewritten. collectd now supports unicast
478 and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
479 be set in the configfile.
481 2006-01-24, Version 3.6.2
482 * Due to a bug in the configfile handling collectd wouldn't start in
483 client mode. This released fixes this.
485 2006-01-20, Version 3.6.1
486 * Due to a bug in `configure.in' all modules and the binary were
487 linked against `libmysqlclient'. This issue is solved by this
490 2006-01-17, Version 3.6.0
491 * A config file has been added. This allows for loading only specific
493 * A `df' plugin has been added.
494 * A `mysql' plugin has been added.
495 * The `ping' plugin doesn't entirely give up hope when a socket error
496 occurred, but will back of and increase the intervals between tries.
498 2006-01-21, Version 3.5.2
499 * Fixed yet another bug in the signal handling.. Stupid typo..
500 * Improved the ping plugin to not give up on socket errors (backport
503 2005-12-18, Version 3.5.1
504 * The PID-file is now deleted correctly when shutting down the daemon.
505 * SIGINT and SIGTERM are now handled correctly.
507 2005-12-16, Version 3.5.0 (Revision 326)
508 * A bug in the `load' module under Solaris has been fixed.
509 * The `users' module has been contributed by Sebastian Harl. It counts

511 * The CPU module now works under FreeBSD without the use of
512 `libstatgrab', however SMP support is missing.
513 * The default directories for the RRD files and the PID file now
514 depend on the compile time setting of `localstatedir'.
516 2005-11-15, Version 3.4.0 (Revision 236)
517 * A PID-file is written to /var/run upon startup. Thanks to `Tommie'
518 from gentoo's bugzilla for writing the patch.
519 * The build dependency for librrd has been removed. Binaries built
520 without librrd are client-only and will multicast their value as
521 with the `-c' argument.
522 * A patch by Peter Holik adds a module for monitoring CPU frequencies.
523 * The newly introduced `-f' switch prevents daemon initialization
524 (forking, closing standard filehandles, etc.) Thanks to Alvaro
525 Barcellos for this patch.
527 2005-11-04, Version 3.3.0 (Revision 216)
528 * New modules have been added:
529 - `serial', for monitoring traffic on the serial interfaces
530 - `nfs', for graphing NFS procedure calls
531 - `tape', traffic from/to tape devices
532 * The memory.rrd now accepts more than 4Gig of memory.
534 2005-10-26, Version 3.2.0 (Revision 200)
535 * Support for graphing the processes has been added (thanks to Lyonel
537 * If reading from hddtemp fails collectd will increase the time
538 between polls up to one day.
539 * The init.d files have been improved.
540 * Problems with the spec file have been fixed.
542 2005-10-16, Version 3.1.0 (Revision 194)
543 * Added the `setsid' syscall to the startup code.
544 * Support for hddtemp has been added (thanks to Vincent Stehlé)
546 2005-09-30, Version 3.0.0 (Revision 184)
547 * The ability to send/receive data to/from the network (think
548 multicast) has been added.
549 * Modules have been split up into shared libraries can be loaded at
550 runtime. The biggest advantage is that the core program doesn't need
551 to be linked against an external library.
552 * A patch by George Kargiotakis has been applied: It fixes the sensors
553 behaviour then more than one sensor is being queried.
555 2005-09-16, Version 2.1.0 (Revision 172)
556 * A module for swap statistics has been added.
558 2005-09-09, Version 2.0.0 (Revision 135)
559 * Filenames can no longer be configured at program startup. The only
560 options as of this version are the directory and ping hosts.
561 * CPU statistics now include Wait-IO. If provided under Linux IRQ and
562 Soft-IRQ statistics are added to `System'.
563 * Diskstats now collect read and write bytes, not sectors.
564 * Ping statistics can now be collected for more than one host. There
565 is no default any more: If no host is given no host will be pinged.
566 * A self-written patch for libping has been applied so it builds
569 2005-09-01, Version 1.8.1 (Revision 123)
570 * Much improved configure-script: libraries and features may now be
572 * More detailed warnings/error messages when RRD update fails.
574 2005-08-29, Version 1.8.0:
575 * Support for collecting disk statistics under Solaris.
577 2005-08-25, Version 1.7.0:
578 * Support for libstatgrab[1] for load, memory usage and network
579 traffic. CPU- and disk-usage are not (yet) supported, since
580 libstatgrab returns insufficient information. I will contact the
582 * Improved the CPU-initialization code for Solaris. Apparently CPUs
583 aren't necessarily counted linear which is now handled correctly.

586 2005-08-21, Version 1.6.0:
587 * Basic support for Solaris: System load and cpu-usage can be
588 collected under Solaris, too. Other stats will follow later.
589 * Many fixes in the autoconf-script
590 * Collection/Museum scripts have been added under contrib/museum
591 * collectd may now be started in unprivileged mode, though ping
592 statistics will not work.
594 2005-07-17, Version 1.5.1:
595 * Diskstats-RRDs now use major/minor for naming. Some systems have
596 weird strings as disk-names..
598 2005-07-17, Version 1.5:
599 * A new module, diskstats, has been added. It collects information
600 about the disks and partitions.
602 2005-07-11, Version 1.4.2:
603 * The meminfo module has been changed to work with more platforms
604 and/or kernel versions.
606 2005-07-10, Version 1.4.1: Correct traffic stats
607 * The traffic rrd-file is now created with DS-type `COUNTER' which I
608 forgot to correct when I changed that module.
610 2005-07-09, Version 1.4: More traffic stats
611 * Traffic is now collected for all interfaces that can be found
612 * Temperature-statistics are read from lm-sensors if available
614 2005-07-08, Version 1.3: CPU stats
615 * Collecting CPU statistics now
617 2004-07-12, Version 1.2: Using syslog
618 * collectd is now using the syslog facility to report errors, warnings
620 * The default directory is now /var/db/collectd
622 2004-07-10, Version 1.1: Minor changes
623 * Nothing really useful to say ;)
625 2004-07-09, Version 1.0: Initial Version
626 * The following modules are provided:
