2009-09-13, Version 4.8.0
* collectd: Two new data source types, “DERIVE” and “ABSOLUTE”, have
been added. “DERIVE” can be used for counters that are reset
occasionally. Thanks to Mariusz Gronczewski for implementing this.
* thresholds: The advanced threshold options “Percentage”, “Hits”, and
“Hysteresis” have been added. Thanks to Andrés J. Díaz for hit
patches.
* curl_json plugin: The new cURL-JSON plugin reads JSON files using
the cURL library and parses the contents according to user
specification. Among other things, this allows to read statistics
from a CouchDB instance. Thanks to Doug MacEachern for the patch.
* df plugin: Using the new “ReportByDevice” option the device rather
than the mount point can be used to identify partitions. Thanks to
Paul Sadauskas for the patch.
* dns plugin: The possibility to ignore numeric QTypes has been added.
Thanks to Mirko Buffoni for the patch.
* GenericJMX plugin: The new, Java-based GenericJMX plugin allows to
query arbitrary data from a Java process using the “Java Management
Extensions” (JMX).
* madwifi plugin: The new MadWifi plugin collects information about
Atheros wireless LAN chipsets from the MadWifi driver. Thanks to
Ondrej Zajicek for his patches.
* network plugin: The receive- and send-buffer-sizes have been made
configurable, allowing for bigger and smaller packets. Thanks to
Aman Gupta for the patch.
* olsrd plugin: The new OLSRd plugin queries routing information from
the “Optimized Link State Routing” daemon.
* rrdtool plugin: A new configuration option allows to define a random
write delay when writing RRD files. This spreads the load created by
writing RRD files more evenly. Thanks to Mariusz Gronczewski for the
patch.
* swap plugin: The possibility to collect swapped in/out pages has
been added to the Swap plugin. Thanks to Stefan Völkel for the
patch.
* tokyotyrant plugin: The new TokyoTyrant plugin reads the number of
records and file size from a running Tokyo Tyrant server. Thanks to
Paul Sadauskas for the patch.
* unixsock plugin: Add the “GETTHRESHOLD” command. This command can be
used to query the thresholds configured for a particular identifier.
* write_http plugin: The new Write HTTP plugin sends the values
collected by collectd to a web-server using HTTP POST requests.
Thanks to Paul Sadauskas for the patch.
* zfs_arc plugin: The new ZFS ARC plugin collects information about
the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
(ZFS). Thanks to Anthony Dewhurst for the patch.
* empty_counter match: The new Empty Counter match matches value
lists, where at least one data source is of type COUNTER and the
counter value of all counter data sources is zero.
2009-09-13, Version 4.7.3
* collectd: Fix a possible but very rare invalid “free” in the caching
code. Thanks to Sebastian Harl for the patch.
* collectd: Remove old values when a cache entry is marked as missing.
This way the “GETVAL” command of the UnixSock plugin doesn't return
old, no longer valid values when this happens. Thanks to Andrés J.
Díaz for the patch.
* collectd: The “plugin_unregister_read” function has been fixed.
* apache, ascent, bind, curl, nginx plugins: Advise the cURL library
to follow redirects. Thanks to Joey Hess for reporting this bug.
* df plugin: Check the ignorelist before stating the file system,
possibly reducing the number of stats considerably. Thanks to Joey
Hess for reporting this bug.
* iptables plugin: Support for the new libiptc API has been added.
Thanks to Sebastian Harl for the patch. The build system has been
updated to the plugin only includes the shipped header files when it
is linked with the shipped library, too.
* java plugin: Delay creating the JVM until after the daemon has
forked. The JVM internally creates threads that are lost when
forking. This means that Java-based plugins are now configured
during the init-phase, i. e. later than other plugins.
* libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
to Alan Pevec for the patch.
* network plugin: Fix the handling of the “CacheFlush” option: The
value was assigned to a wrong variable. The initialization of the
gcrypt library, which is used for signing / encrypting traffic, has
been fixed. Thanks to Luke Heberling for the patch.
* powerdns plugin: Set a timeout when reading data from the datagram
socket. Handling of the “LocalSocket” option has been fixed. An
incorrectly used “type” has been corrected. Thanks to Luke Heberling
for his patches.
2009-07-19, Version 4.7.2
* Build system: Support for `DESTDIR' has been fixed in the Java
bindings.
* collectd: Okay-notifications have been fixed. Thanks to Andrés J.
Díaz for fixing this bug.
* collectd: A programming error has been fixed in the notification
code. The bug may result in an assertion failure.
* memcached plugin: Portability fix for Solaris. Thanks to Amit Gupta
for reporting the bug.
* ping plugin: Link the plugin with libm.
2009-06-02, Version 4.7.1
* Build system: Detection of Java has been improved and missing
details have been added to the configuration summary. Support for
libtool 2.2 has been added.
* collectd: Two bugs with the threshold checking have been fixed. The
first one prevented thresholds to be checked at all, the second one
caused wrong behavior with the persistency option. Thanks to Andrés
J. Díaz for fixing these problems.
* collectd: Handling of the `Include' configuration option has been
fixed.
* rrdtool plugin: Make sure initialization is run only once. This
resolves problems under Solaris and potentially other systems.
Thanks to Amit Gupta for reporting this bug.
* java plugin: Make it possible to use dots ('.') instead of slashes
('/') as the class separator. Thanks to Randy Rizun for pointing
this out.
* swap plugin: A work-around for 32-bit Solaris has been added. Thanks
to Doug MacEachern for the patch.
2009-05-11, Version 4.7.0
* apache plugin: Support to query multiple servers has been added.
Thanks to Amit Gupta for the patch.
* apache plugin: Handling of lighttpd's scoreboard statistics has been
improved. Thanks to Amit Gupta for the patch.
* conntrack plugin: The new conntrack plugin collects the connection
tracking table size. Thanks to Tomasz Pala for the patch.
* fscache plugin: The new fscache plugin collects statistics about
Linux' file-system based caching framework. Thanks to Edward
Konetzko for the patch.
* gmond plugin: The new gmond plugin can receive and interpret
multicast traffic from Ganglia's gmond daemon.
* java plugin: The new java plugin exports the collectd API to Java,
making it possible to write extensions to collectd in Java.
* memcachec plugin: The new memcachec plugin queries data from a
memcached daemon and parses it similar to the cURL plugin. Thanks to
Doug MacEachern for the initial code.
* memcached plugin: Support for connections over UNIX domain sockets
has been added. Thanks to Franck Lombardi for the patch.
* memory plugin: Support for OpenBSD and possibly other *BSDs has been
added. Thanks to Simon Kuhnle for the patch.
* mysql plugin: Support to query multiple databases has been added.
Thanks to Doug MacEachern for the patch.
* mysql plugin: Master/slave statistics have been added.
* mysql plugin: Lock statistics have been added. Thanks to Rodolphe
Quiédeville for the patch.
* network plugin: The possibility to sign or encrypt network traffic
has been added.
* protocols plugin: The new protocols plugin provides information
about network protocols, such as IP, TCP and UDP.
* snmp plugin: The intervals given in the configuration of the SNMP
plugin must no longer be a multiple of the global interval.
* table plugin: The new Table plugin provides parsing for table-like
structured files, such as many files beneath /proc.
* ted plugin: The new TED plugin reads power consumption measurements
from “The Energy Detective” (TED). Thanks to Eric Reed for this
plugin.
* onewire plugin: The new `Interval' option allows collecting
information from OneWire sensors at arbitrary intervals.
* ping plugin: Support for collecting the drop rate and standard
deviation of round-trip times has been added.
* uptime plugin: The new uptime plugin can collect the server's
uptime. Thanks to Marco Chiappero for the patch.
2009-09-10, Version 4.6.5
* collectd: Remove old values when a cache entry is marked as missing.
This way the “GETVAL” command of the UnixSock plugin doesn't return
old, no longer valid values when this happens. Thanks to Andrés J.
Díaz for the patch.
* apache, ascent, bind, curl, nginx plugins: Advise the cURL library
to follow redirects. Thanks to Joey Hess for reporting this bug.
* df plugin: Check the ignorelist before stating the file system,
possibly reducing the number of stats considerably. Thanks to Joey
Hess for reporting this bug.
* iptables plugin: Support for the new libiptc API has been added.
Thanks to Sebastian Harl for the patch. The build system has been
updated to the plugin only includes the shipped header files when it
is linked with the shipped library, too.
* libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
to Alan Pevec for the patch.

for many fixes and providing a build system for many platforms,
Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
providing an OpenBSD system.
* collectd: Two bugs with the threshold checking have been fixed. The
first one prevented thresholds to be checked at all, the second one
caused wrong behavior with the persistency option. Thanks to Andrés
J. Díaz for fixing these problems.
* collectd: Handling of the `Include' configuration option has been
fixed.
* battery plugin: Don't complain about a missing directory every
interval.
* exec plugin: Allow executed programs to close STDERR. Thanks to

* filter subsystem: Allow `Chains' without default targets.
* liboping: A patch to comply with strict aliasing rules has been
added.
* timediff match: Fix a typo: The match was registered with a wrong
name which prevented this match to be used as documented. Thanks to
Bruno Prémont for finding this problem.
* bind plugin: Fix collection of the cached RR sets. The number of RR
sets currently in the cache was collected as a counter value, which
is nonsense. Thanks to Bruno Prémont for implementing this.
* dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
primarily BSDs, don't take it well and crash.
* oracle plugin: Portability to 64 bit systems has been improved.
* postgresql plugin: The default configuration has been improved.
* rrdtool plugin: Fix a possible race condition: If the network plugin
is brought and dispatches a value before the rrdtool plugin is
initialized, the daemon may crash.
2009-02-22, Version 4.6.1
* collectd: Many documentation fixes.
* Collectd::Unixsock: Error handling has been improved.
* regex match: Don't link with the PCRE library.

user to use `matches' and `targets' to control value processing.
* collectd: The new `-T' command line argument allows more in-depth
testing of a configuration. Thanks to Doug MacEachern for the patch.
* collectd-nagios: The Nagios integration command has been updated to
use libcollectdclient. The `percentage' aggregation function has
been added. Thanks to Fabian Linzberger for the patch.

statistics, allowing very detailed name server statistics. Thanks to
Bruno Prémont for this plugin.
* cpu plugin: Report `interrupt' separately when using
sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
example for native OpenBSD support, has been added. Thanks to Simon
Kuhnle for the patch.
* csv plugin: Make it possible to write values to STDOUT instead of
files. This is meant for testing purposes mostly. The output written
to STDOUT is compatible with the exec plugin. Thanks to Doug
MacEachern for the patch.
* curl plugin: This new plugin can be used to read web pages and parse
them using the same mechanism that's used in the tail plugin.
* dbi plugin: This new plugin allows you to connect to a variety of
relational databases and use SQL to gather custom statistics from
it. It is similar to the already existing PostgreSQL plugin but uses
libdbi to communicate with the database(s).
* interface plugin: Use the ignorelist framework when selecting /
ignoring interfaces. This allows one to use regular expressions to
select interfaces, too.
* ipmi plugin: Handle temporary IPMI error conditions more gracefully.
Thanks to Bruno Prémont for this patch.
* memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
for the patch.
* mysql plugin: Allow connecting to a database via the UNIX domain
socket, too. Thanks to Mirko Buffoni for the patch.

database and use SQL to gather custom statistics from it. It is
similar to the already existing PostgreSQL plugin.
* perl plugin: Compatibility fixes for broken versions of Perl 5.10
have been added.
* perl plugin: Export the newly added plugin_write() to Perl plugins.
* perl plugin: Added support for `notification meta data'.
* perl plugin: Added support for the `filter chain' infrastructure by
allowing plugins to register `matches' and `targets'.
* postgresql plugin: The preferred configuration syntax has been
updated to be in line with the syntax used by the new dbi and oracle
plugins. The compatibility code for the old syntax is present.
Support for the new `Result' blocks and the interval parameter has
been added.
* processes plugin: Stacksize and virtual memory usage statistics have
been added. Portability fixes.
* rrdcached plugin: This new plugin uses the (still in development)
RRD accelerator daemon, rrdcached. This daemon works very similar to
the original rrdtool plugin of collectd, but adds some more nice
features.
* swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
added.

code. Thanks to "thated" for reporting this.
2009-01-02, Version 4.5.2
* build system: Check for `mysql.h' and `mysql/mysql.h', since the
file may be in both locations, especially when the database was
installed in a non-standard path. Thanks to Dusty Doris for
reporting this.
* build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
Solaris, in the configure script automatically.
* build system, tcpconns plugin: Check for `kvm_nlist' and
`kvm_openfiles' before enabling the plugin: Solaris provides a KVM
library with similar functions to the BSD variant, but doesn't
provide these necessary functions.
* collectd.conf(5): Various fixes and clarifications.
* collectd: Remove a GNUism (unnamed unions), thus improving
portability.
* collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
This solves portability problems, especially for Solaris.
* dns plugin: Fix a portability problem with NetBSD.
* filecount plugin: Fix an off-by-one error. This error may cause a
segmentation fault.
* network plugin: Fix the handling of `type' in the network protocol.
Due to a programming mistake, only 4 or 8 bytes would be copied to a
much larger buffer. This caused the `type' to be transferred much
more often than necessary. In some cases, e. g. the `cpu' and
`cpufreq' plugins being used at the same time, data may be corrupted
in those files. Thanks to Bruno Prémont for debugging and reporting
this issue.
* processes plugin: Fix a possible segmentation fault when specifying
invalid configuration options.
* unixsock plugin: Make sure the initialization function is run only
once. This resolves a file descriptor leak under systems which run
the initialization more than once, such as Solaris.
2008-10-16, Version 4.5.1
* build system: Change `--enable-<plugin>' to abort with an error if
dependencies are not met. Thanks to Bruno Prémont for the patch.
Also, the poisoning of various string functions has been restricted
to debug builds.
* collectd: Fix a memory leak in the global value cache. With every
*missing* value a couple of bytes would be leaked. Another memory
leak in the configuration handling code has been fixed. Thanks to
Niraj Tolia for reporting these issues.
* collectd: Fix an off-by-one error in the ignorelist functionality.
When using regular expressions, the last character would be missing,
possibly matching differently from what one would expect.
* collectdmon: Don't block SIGCHLD. This fixes a potential portability
problem.
* collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
Linzberger for reporting the bug.
* iptables plugin: Fix an off-by-one error. If a string was just one
character too long, it was truncated instead of reporting an error.
* network plugin: Fix a memory leak in the configuration handling
code. Thanks to Niraj Tolia for reporting this issue.
* perl plugin: Log an error message if bootstrapping `Collectd' fails.
* postgresql plugin: Don't reopen connection during reinitialization.
This fixes a bug under Solaris and potentially other platforms.
Missing calls to `PQclear' have been added, too. This fixes memory
leaks. Thanks to ``Admin'' for reporting these bugs.
* snmp plugin: Don't expect null-terminated strings from the Net-SNMP
library.
* tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
problems with some `libc's. Thanks to Matthias Lay for reporting the
bug.

means that you can configure threshold values for each data
instance. If this threshold is exceeded a notification will be
created.
* collectd: The new `FQDNLookup' option tells the daemon to use the
full qualified domain name as the hostname, not just the host part
es returned by `gethostname(2)'.
* collectd: Support for more than one `TypesDB' file has been added.
This is useful when one such file is included in a package but one
wants to add custom type definitions.
* collectd: The `Include' config option has been expanded to handle
entire directories and shell wildcards.

domain name lookups in this plugin.
* perl plugin: Many internal changes added support for handling multiple
threads making the plugin reasonably usable inside collectd. The API has
been extended to support notifications and export global variables to
Perl plugins; callbacks now have to be identified by name rather than a
pointer to a subroutine. The plugin is no longer experimental.
* uuid plugin: The new UUID plugin sets the hostname to an unique
identifier for this host. This is meant for setups where each client
may migrate to another physical host, possibly going through one or
more name changes in the process. Thanks to Richard Jones from
Red Hat's Emerging Technology group for this plugin.
* libvirt: The new libvirt plugin uses the `libvirt' library to query
CPU, disk and network statistics about guest systems on the same
physical server. Thanks to Richard Jones from Red Hat's Emerging

and dispatching incoming packets. Versions prior to this may have
problems in high-load situations, where the socket receive buffers
overflows, resulting in gaps in the data.
+ Use `memcpy' when constructing/parsing a package to avoid
alignment problems on weird architectures, such as Sparc.
+ Translate doubles to/from the x86 byte representation to ensure
cross-platform compatibility.
* ping plugin: Correct the handling of the `TTL' setting.
* rrdtool plugin: Ensure correct handling of the `RRATimespan' option.
* swap plugin: Reapply a patch for Solaris.
* tcpconns plugin: Portability improvements.

2007-12-28, Version 4.2.3
* sensors plugin: Updated the plugin to build and work with version 3
of the libsensors library.
2007-12-15, Version 4.2.2
* nginx plugin: Incorrect comparison of strings lead to a segfault
when using the plugin. Thanks to Saulius Grigaliunas for fixing

incorrectly and basically always active. Thanks to Luke Heberling
for fixing this.
2007-11-08, Version 4.2.1
* tcpconns plugin: Don't complain about a missing file if IPv6 is not
enabled on the host.
* snmp plugin: Fix a memory leak.
2007-10-27, Version 4.2.0
* collectd: The new config option `Include' lets you include other
configfiles and thus split up your config into smaller parts. This
may be especially interesting for the snmp plugin to keep the data
definitions separate from the host definitions.
* ipvs plugin: The new `ipvs' plugin collects IPVS connection statistics
(number of connections, octets and packets for each service and
destination). Thanks to Sebastian Harl for this plugin.
* memcached plugin: The new `memcached' plugin connects to a memcached
daemon process and collects statistics of this distributed caching
system. Thanks to Antony Dovgal for contributing this plugin.
* nginx plugin: The new `nginx' plugin reads the status page of an
nginx daemon and saves the handled connections and requests.
* perl plugin: Many changes, including the added `EnableDebugger'
config option which lets you debug your Perl plugins more easily.
* rrdtool plugin: Use the thread-safe RRD-library if available. Try to
be more thread-safe otherwise by locking calls to the library.
* snmp plugin: Added the options `Scale' and `Shift' to Data-blocks to
correct the values returned by SNMP-agents. If a <data> block is
defined as `table' the instance is now optional. The sequence number
is used as the type-instance in this case. The new `InstancePrefix'
option allows to add arbitrary prefixes to the type-instance.
* tcpconns plugin: The new `tcpconns' plugin collects the number of
certain TCP connections and what state they're in. This can be used
to see how many connections your FTP server has to handle or how
many outgoing connections your mailserver has open.
2008-01-11, Version 4.1.6
* unixsock plugin: A bug in the unixsock plugin caused it not to set
the permission on the socket as documented in the manpage. Thanks to
Evgeny Chukreev for fixing this issue.

* build system: Further improve the detection of libraries.
* netlink plugin: Build issues under some older versions of the Linux
includes (i. e. Debian Sarge) have been fixed.
* snmp plugin: Fix a potential segfault when a host times out. Add
support for the `timeticks' type.
2007-09-12, Version 4.1.1
* Build system: The detection of `libnetlink' has been improved.
* collectd: The documentation has been fixed in numerous places.
* exec plugin: Setting the group under which to run a program has been
fixed.
* collectd: The `sstrerror' function was improved to work correctly
with the broken GNU version of `strerror_r'.
* collectd: Write an error message to STDERR when loading of a plugin
fails.
* apcups plugin: Fix the `types' used to submit the values: They still
has an `apcups_' prefix which doesn't work anymore.
* rrdtool plugin: Create new RRD-files with the `begin' time set to
whatever the client thinks is `now'..
2007-09-01, Version 4.1.0
* Build system: The build system has been changed to automatically
disable all plugins, which are missing dependencies. The dependency
checking has been removed from the plugins themselves to remove
redundancy.
* Flexible interval: The interval of collected data is now sent along
with the data itself over the network, so that the interval-settings
of server and clients no longer needs to match.
* netlink plugin: The new `netlink' plugin connects to the Linux
kernel using a netlink socket and uses it to query information about
interfaces, qdiscs and classes.
* rrdtool plugin: The cache is now dumped to disk in an extra thread
to not block data collection.
* snmp plugin: The new `snmp' plugin can read values from SNMP enabled
network devices, such as switches, routers, thermometers, rack
monitoring servers, etc. The collectd-snmp(5) manpage documents this
plugin.
* unixsock plugin: Added the `LISTVAL' command.
* xmms plugin: The new `xmms' plugin graphs the bitrate and frequency
of music played with xmms.
2007-09-28, Version 4.0.9
* apcups plugin: Fix reporting of the `load percent' data.
* wireless plugin: Correct the handling of cards returning signal and
noise quality as percentage.
* perl plugin: Fix a possible buffer overflow in get_module_name().
2007-09-12, Version 4.0.8
* collectd: The `sstrerror' function was improved to work correctly
with the broken GNU version of `strerror_r'.
* collectd: Write an error message to STDERR when loading of a plugin
fails.
* apcups plugin: Fix the `types' used to submit the values: They still
has an `apcups_' prefix which doesn't work anymore.
* rrdtool plugin: Create new RRD-files with the `begin' time set to
whatever the client thinks is `now'..
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.
* processes plugin: Fix a potential segmentation fault.
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.

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.
2007-09-28, Version 3.11.7
* wireless plugin: Correct the handling of cards returning signal and
noise quality as percentage.
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 startup 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
