2007-08-26, Version 4.0.7
* documentation: Some typos have been fixed and some information has
been improved.
* build system: Many fixes for detecting libraries in unusual places,
such as on RedHat systems. The affected libraries are `libcurl',
`libmysql', and `libupsclient'.
* network plugin: Allow the `Port' option to be specified as a number
(i. e. without quotes).
* nut plugin: A fix allows linking the nut plugin against
libupsclient, version >= 2.2.0.
2007-07-30, Version 4.0.6
* sensors plugin: Fix the ignorelist functionality: Only the `type
instance' was used to match against the list, but the documentation
told otherwise. This release fixes the code, so it complies with the
documentation.
* syslog plugin: Call `openlog' right when the plugin is loaded, so
configuration messages will end up in the logging facility.
* conrtib/fedora: The contributed specfile for Fedora has been
updated.
2007-07-05, Version 4.0.5
* Portability: More fixes for OpenBSD have been included.
2007-06-24, Version 4.0.4
* cpu plugin: Fixed the Solaris code.
* dns plugin: Fixed a build issue for OpenBSD.
* interface plugin: Fixed the Solaris code.
* load plugin: Fixed the alternative `/proc' Linux code.
* memory plugin: Fixed the Solaris code.
* oconfig: Don't require `-lfl' anymore.
2007-06-19, Version 4.0.3
* cpu plugin: Fix the Darwin / Mac OS X code.
* ping plugin: Use the return value of `getpid', not its address.
* csv, rrdtool plugin: Fixed a bug that prevented an buffer to be
initialized correctly.
* configure: Added `--with-nan-emulation' to aid cross compilation.
2007-06-12, Version 4.0.2
* hddtemp and ntpd plugin: Corrected the parsing of port numbers when
they're given in numerically form.
2007-06-07, Version 4.0.1
* iptables plugin: A bug in the configuration routine has been fixed.
Setting a comment in the configfile will no longer cause a
segmentation fault.
2007-06-03, Version 4.0.0
* collectd: The plugin-infrastructure has been changed to allow for
more types of plugins, namely `write' and `log' plugins.
* collectd: The read-function has been changed to read many plugins in
parallel, using threads. Thus, plugins generally need to use
thread-safe functions from now on.
* collectd: The '-t' command line options allows to perform syntax tests
of the configuration file and exit immediately.
* csv plugin: The new `csv' plugin handles output to `comma separated
values'-files.
* rrdtool plugin: The new `rrdtool' plugin handles output to
RRD-files. Data can be cached to combine multiple updates into one
write to increase IO-performance.
* network plugin: The new `network' plugin handles IO via the network.
It implements a different, much more extensible protocol which can
combine many values in one packet, decreasing the number of UDP-
packets being sent. It can read from and send to the network and
with the appropriate configuration even forward packets to other
networks.
* unixsock plugin: The new `unixsock' plugin provides an interface to
communicate with the daemon while it is running. Right now the
commands `GETVAL' and `PUTVAL' are implemented, but more are to
come.
* perl plugin: The new `perl' plugin allows you to write extensions
for collectd in the scripting-language Perl.
* logfile plugin: The new `logfile' plugin writes logmessages to files
or STDOUT or STDERR.
* syslog plugin: The new `syslog' plugin sends logmessages to the
system's syslog daemon.
* entropy plugin: The new `entropy' plugin collects the amount of
entropy currently being available to the system.
* exec plugin: The new `exec' plugin forks child processes and reads
back values provided by the forked processes.
* iptables plugin: The new `iptables' plugin reads counters from
iptables rules. Thanks to Sjoerd van der Berg for contributing this
plugin.
* irq plugin: The new `irq' plugin collects the IRQ-counters. Thanks
to Peter Holik for contributing this plugin.
* nut plugin: The new `nut' plugin connects the upsd of the `network
ups tools' and reads information about the connected UPS.
* apache plugin: Support for lighttpd's `BusyServers' (aka.
connections) field was added by Florent Monbillard.
* collectd-nagios: The new `collectd-nagios' binary queries values
from collectd, parses them and exits according to Nagios-standards.
* manpages: The manpages have been improved a lot.
2007-08-31, Version 3.11.6
* processes plugin: Fix a potential segmentation fault.
2007-05-29, Version 3.11.5
* configure: Added `AC_SYS_LARGEFILE' for LFS.
* ntpd plugin: Fix a potential buffer overflow.
* processes plugin: Fix a bug when run under Linux 2.4. All processes
were accounted as `zombies'.
2007-04-10, Version 3.11.4
* dns plugin: Change the order of includes to make the plugin compile
under FreeBSD.
2007-03-30, Version 3.11.3
* configure: Have the configure-script define `HAVE_LIBKSTAT' instead
of the unused `COLLECT_KSTAT'.
2007-02-11, Version 3.11.2
* plugin: Catch NULL-pointer and try to fix them. Otherwise the
NULL-pointer may have been passed to `printf' which causes a
segfault with some libcs.
2007-02-10, Version 3.11.1
* df plugin: Some wrong defines have been fixed so the plugin works
under Solaris again.
* dns plugin: The usage of a struct has been fixed to work with
non-GNU libcs.
* processes plugin: Some missing defines have been added so the plugin
compiles cleanly under FreeBSD and presumably other UNIXes.
2006-12-22, Version 3.11.0
* collectd: The new command line option `-P' makes it easier for
distributors to change the location of PID-files.
* collectd: The daemon shuts down faster now which makes it easier to
write init.d-scripts for it.
* apache plugin: Increase the buffersize to 16k, because the 4k buffer
caused problems every now and then.
* df plugin: New config options allow to ignore certain mountpoints,
filesystem types or devices.
* dns plugin: The new dns plugin uses `libpcap' to capture DNS traffic
and interprets it. It collects traffic as well as qtype, opcode and
rcode counts.
* email plugin: Sebastian Harl has contributed this plugin which
counts received mails in categories (e. g. ham, spam, virus), spam
score (as given by SpamAssassin) and check types.
* mbmon plugin: Flavio Stanchina has contributed this plugin which
uses `mbmon' to gather information from sensors on the motherboard.
* processes plugin: Collect detailed statistics for configured
processes, that's process and thread count, CPU usage, resident
segment size and pagefaults.
* multimeter plugin: Peter Holik contributed a new plugin which
queries multimeters.
* sensors plugin: Lubos Stanek has put much effort into improving this
plugin, including `extended naming', collection of voltage values
and the possibility to ignore certain values.
2006-12-21, Version 3.10.4
* Max Kellermann has identified a bug in the server routine: When
opening a socket fails the daemon will (re)try opening the socket in
an endless loop, ultimately leading to a `EMFILE' error.
2006-11-04, Version 3.10.3
* Lubos Stanek has identified a bug in the ntpd-plugin: When the
ntpd's reply was sent in more than one packet, the buffer size was
calculated incorrectly, resulting in the reading of uninitialized or
freed memory.
2006-11-01, Version 3.10.2
* The sample config file has been improved.
* Errors in the manpages have been corrected.
* The ping-plugin now adds hosts during initialization, not during
startup. This speeds up starup when no network connectivity is
available. Also, the hosts are being added later when the network is
available.
* Improved BSD-support for the df-plugin.
* Fixed syntax errors in the swap-plugin for Mac OS X.
* Fix a wrong structure being passed to `getnameinfo' in the ntpd-
plugin.
* Don't disable the mysql-plugin if connecting to the database fails
during initialization. Instead, try again in increasing intervals.
2006-07-19, Version 3.10.1
* A bug in the apcups plugin was fixed: Is the plugin is loaded, but
the apcups cannot be reached, unconnected sockets will pile up and
eventually lead to `Too many open files' errors.
2006-07-09, Version 3.10.0
* The `disk' plugin has been ported to Darwin.
* The `battery' plugin should work on many Apple computers now.
* The `traffic' plugin can now ignore certain interfaces. Also,
statistics for sent/received packets and errors have been added.
* A plugin to monitor APC UPSes using `apcupsd' has been added. Thanks
to Anthony Gialluca for contributing this plugin and providing me
with a test environment :)
* A plugin for moniroting an NTP instance and the local clock drift
has been added.
2006-06-25, Version 3.9.4
* The Solaris code in the `swap' plugin has been changed to reflect
the numbers returned by `swap -s'. Thanks to Christophe Kalt for
working this out.
* The debugging system has been fixed to work with the Sun libc.
* When built without librrd the variable `operating_mode' could be
uninitialized. Thanks to David Elliot for reporting the bug.
2006-06-01, Version 3.9.3
* Fixed the ping-plugin under FreeBSD and Mac OS X. Potentially other
operating systems also profit from the changes, but I wasn't able to
check that.
* Changed the build system to find the netinet-includes under FreeBSD
and therefore successfully build the `liboping' library there.
2006-05-09, Version 3.9.2
* Applied a patch to the `liboping' library. Due to a bug in the
sequence checking the `ping' plugin stopped working after
approximately 7.6 days.
2006-05-09, Version 3.8.5
* Applied a patch to the `liboping' library. Due to a bug in the
sequence checking the `ping' plugin stopped working after
approximately 7.6 days.
2006-04-21, Version 3.9.1
* Build issues with Solaris and possible other architectures have been
resolved.
* Problems when building the `apache'-plugin without `libcurl' have
been resolved.
* A bug in the `ping' plugin has been fixed. Sorry folks.
2006-04-02, Version 3.9.0
* A plugin to monitor the Apache webserver has been added.
* A plugin to collect statistics about virtual servers using VServer.
Thanks to Sebastian Harl for writing
this plugin :)
* A plugin for wireless LAN cards has been added. It monitors signal
strength, link quality and noise ratio..
* A plugin for Apple hardware sensors has been added.
* An option to compile collectd with different `step' and `hearbeat'
settings has been added. The size of RRAs is no longer static but
calculated based on the settings for `step' and `width'.
* The `ping' plugin can now be configured to use a certain TTL.
* A plugin to monitor the hardware sensors of Apple computers has been
added.
* The plugins `cpu', `memory', `processes' and `traffic' have been
ported to Mach/Darwin (Mac OS X).
* The `log mode' has been contributed by Christophe Kalt. It writes
the data into text files rather than RRD files.
2006-04-09, Version 3.8.4
* Applied patch by Vincent Stehlé which improves the disk-name
resolution in the `hddtemp' plugin for Linux systems.
2006-04-02, Version 3.8.3
* Applied a patch by James Byers: The MySQL plugin was not working
with MySQL 5.0.2 or later.
2006-03-14, Version 3.8.2
* `utils_mount.c' has been changed to not use the `MNTTAB' defined by
the GNU libc, because it points to `/etc/fstab' rather than
`/etc/mtab'.
2006-03-13, Version 3.8.1
* Fixes for building collectd unter FreeBSD, Mac OS X and Solaris.
* Fixes in the debian `postinst' and `init.d' scripts.
2006-03-09, Version 3.8.0
* The `ping' plugin no longer uses `libping' but a self written
library named `liboping'. With this library it's possible to ping
multiple IPv4 and IPv6 addresses and hostnames - in parallel.
2006-02-18, Version 3.7.2
* A simple bug in the `battery' plugin has been fixed. It should now
work with ACPI based batteries as well. Thankt to Sebastian for
fixing this.
* Fixing a bug that prevented collectd to be built without librrd.
Thanks to Werner Heuser for reporting it.
2006-02-04, Version 3.7.1
* The new network code has been improved to build with older versions
of glibc.
* Fix in `libping' sets the ICMP sequence on outgoing packets. Thanks
to Tommie Gannert for this patch.
2006-01-30, Version 3.7.0
* The `battery' plugin has been added. It collects information about
laptop batteries..
* The MySQL plugin has been improved: It now writes two more RRD
files, `mysql_qcache.rrd' and `mysql_threads.rrd'.
* The `cpufreq' plugin now reads another file since the file it did
read so far causes much overhead in the kernel. Also, you need root
to read the old file, but not to read the new one.
* The `hddtemp' plugin can now be configured to connect to another
address and/or port than localhost.
* The `df' plugin now prefers `statvfs' over `statfs'.
* The network code has been rewritten. collectd now supports unicast
and multicast, and IPv4 and IPv6. Also, the TTL of sent packages can
be set in the configfile.
2006-01-24, Version 3.6.2
* Due to a bug in the configfile handling collectd wouldn't start in
client mode. This released fixes this.
2006-01-20, Version 3.6.1
* Due to a bug in `configure.in' all modules and the binary were
linked against `libmysqlclient'. This issue is solved by this
release.
2006-01-17, Version 3.6.0
* A config file has been added. This allows for loading only specific
plugins.
* A `df' plugin has been added.
* A `mysql' plugin has been added.
* The `ping' plugin doesn't entirely give up hope when a socket error
occured, but will back of and increase the intervals between tries.
2006-01-21, Version 3.5.2
* Fixed yet another bug in the signal handling.. Stupid typo..
* Improved the ping plugin to not give up on socket errors (backport
from 3.6.0).
2005-12-18, Version 3.5.1
* The PID-file is now deleted correctly when shutting down the daemon.
* SIGINT and SIGTERM are now handled correctly.
2005-12-16, Version 3.5.0 (Revision 326)
* A bug in the `load' module under Solaris has been fixed.
* The `users' module has been contributed by Sebastian Harl. It counts
currently logged in users.
* The CPU module now works under FreeBSD without the use of
`libstatgrab', however SMP support is missing.
* The default directories for the RRD files and the PID file now
depend on the compile time setting of `localstatedir'.
2005-11-15, Version 3.4.0 (Revision 236)
* A PID-file is written to /var/run upon startup. Thanks to `Tommie'
from gentoo's bugzilla for writing the patch.
* The build dependency for librrd has been removed. Binaries built
without librrd are client-only and will multicast their value as
with the `-c' argument.
* A patch by Peter Holik adds a module for monitoring CPU frequencies.
* The newly introduced `-f' switch prevents daemon initialization
(forking, closing standard filehandles, etc.) Thanks to Alvaro
Barcellos for this patch.
2005-11-04, Version 3.3.0 (Revision 216)
* New modules have been added:
- `serial', for monitoring traffic on the serial interfaces
- `nfs', for graphing NFS procedure calls
- `tape', traffic from/to tape devices
* The the memory.rrd now accepts more than 4Gig of memory.
2005-10-26, Version 3.2.0 (Revision 200)
* Support for graphing the processes has been added (thanks to Lyonel
Vincent)
* If reading from hddtemp failes collectd will increase the time
between polls up to one day.
* The init.d files have been improved.
* Problems with the spec file have been fixed.
2005-10-16, Version 3.1.0 (Revision 194)
* Added the `setsid' syscall to the startup code.
* Support for hddtemp has been added (thanks to Vincent Stehlé)
2005-09-30, Version 3.0.0 (Revision 184)
* The ability to send/receive data to/from the network (think
multicast) has been added.
* Modules have been split up into shared libraries can be loaded at
runtime. The biggest advantage is that the core program doesn't need
to be linked against an external library.
* A patch by George Kargiotakis has been applied: It fixes the sensors
behaviour then more than one sensor is being queried.
2005-09-16, Version 2.1.0 (Revision 172)
* A module for swap statistics has been added.
2005-09-09, Version 2.0.0 (Revision 135)
* Filenames can no longer be configured at program startup. The only
options as of this version are the directory and ping hosts.
* CPU statistics now include Wait-IO. If privided under Linux IRQ and
Soft-IRQ statistics are added to `System'.
* Diskstats now collect read and write bytes, not sectors.
* Ping statistics can now be collected for more than one host. There
is no default any more: If no host is given no host will be pinged.
* A self-written patch for libping has been applied so it builds
cleanly.
2005-09-01, Version 1.8.1 (Revision 123)
* Much improved configure-script: libraries and features may now be
disabled.
* More detailed warnings/error messages when RRD update failes.
2005-08-29, Version 1.8.0:
* Support for collecting disk statistics under Solaris.
2005-08-25, Version 1.7.0:
* Support for libstatgrab[1] for load, memory usage and network
traffic. CPU- and disk-usage are not (yet) supported, since
libstatgrab returns insufficient information. I will contact the
authors.
* Improved the CPU-initialization code for Solaris. Apparently CPUs
aren't neccessarily counted linear which is now handled correctly.
[1]: http://www.i-scream.org/libstatgrab/
2005-08-21, Version 1.6.0:
* Basic support for Solaris: System load and cpu-usage can be
collected unter Solaris, too. Other stats will follow later.
* Many fixes in the autoconf-script
* Collection/Museum scripts have been added unter contrib/museum
* collectd may now be started in unprivileged mode, though ping
statistics will not work.
2005-07-17, Version 1.5.1:
* Diskstats-RRDs now use major/minor for naming. Some systems have
weird strings as disk-names..
2005-07-17, Version 1.5:
* A new module, diskstats, has been added. It collects information
about the disks and partitions.
2005-07-11, Version 1.4.2:
* The meminfo mofule has been changed to work with more platforms
and/or kernel versions.
2005-07-10, Version 1.4.1: Correct traffic stats
* The traffic rrd-file is now created with DS-type `COUNTER' which I
forgot to correct when I changed that module.
2005-07-09, Version 1.4: More traffic stats
* Traffic is now collected for all interfaces that can be found
* Temperature-statistics are read from lm-sensors if available
2005-07-08, Version 1.3: CPU stats
* Collecting CPU statistics now
2004-07-12, Version 1.2: Using syslog
* collectd is now using the syslog facility to report errors, warnings
and the like..
* The default directory is now /var/db/collectd
2004-07-10, Version 1.1: Minor changes
* Nothing really usefull to say ;)
2004-07-09, Version 1.0: Initial Version
* The following modules are provided:
* Load average
* Ping time
* Traffic
* Memory info
