+2013-08-18, Version 5.4.0
+ * collectd: The "LoadPlugin" config option no longer attempts to load
+ plugins twice. If more than one "LoadPlugin" statement or block is
+ encountered, only the first will have any effect.
+ * collectd: The "AutoLoadPlugin" option allows to automatically load
+ plugins for which a configuration is found.
+ * collectd: The "WriteQueueLimitHigh" and "WriteQueueLimitLow" options
+ allow collectd to drop values when under stress, to avoid running out
+ of memory. Thanks to Yves Mettier for his patch.
+ * amqp plugin: The "GraphiteSeparateInstances" and
+ "GraphiteAlwaysAppendDS" options have been added. Thanks to Laurent
+ for the patch.
+ * aquaero plugin: This new plugin reads various metrics, e.g. fan
+ speeds and temperatures, from Aquaero 5, a fan and water cooling
+ control panel. Thanks to Alex Deymo for his patch.
+ * curl plugin: The "MeasureResponseCode" option has been added. Thanks
+ to Jan Matějka for his patch.
+ * curl_json plugin: Support for UNIX domain sockets and array wildcards
+ has been added. Thanks to Jim Radford for his patch.
+ * curl_xml plugin: Support for long URLs has been improved.
+ * cgroups plugin: This new plugin collects CPU accounting information
+ for processes in a cgroup. Thanks to Michael Stapelberg for his patch.
+ * df plugin: The "ValuesAbsolute" and "ValuesPercentage" options have
+ been added. Thanks to Vedran Bartonicek for the patch.
+ * exec plugin: Do UID / GID lookups before forking. This should prevent
+ a race condition in the NSS library. Thanks to Ceri Storey for the
+ patch.
+ * lvm plugin: This new plugin collects size information from Linux'
+ Logical Volume Manager (LVM). Thanks to Chad Malfait for his work.
+ * memcached plugin: Support for increment and decrement counts has been
+ added. Thanks to Blake Matheny for the patch.
+ * mic plugin: This new plugin collects CPU and memory usage, power
+ consumption and temperatures of Intel's Many-Integrated-Core (MIC)
+ architecture, such as Xeon Phi cards. Thanks to Evan Felix for his
+ work.
+ * netlink plugin: This plugin has been converted to use the supported
+ "libmnl" library. Thanks to Andreas Henriksson for his patch.
+ * nginx plugin: Collection of accepted and handled connections has been
+ added. Thanks to Patrick Shan for his patch.
+ * sigrok plugin: This new plugin collects metrics from sigrok, a signal
+ processing framework reading various hardware devices, from light
+ meters to spectrum analyzers. Thanks to Bert Vermeulen for his patch.
+ * statsd plugin: This new plugin listens to a UDP socket and reads
+ metrics in the StatsD format.
+ * varnish plugin: Many additional metrics have been added. Thanks to
+ Nick Stenning for his patch.
+ * write_graphite plugin: Support for "UDP" has been added. Thanks to
+ Javier Maestro for his patch.
+ * write_riemann plugin: The "TTLFactor" option has been added.
+ * zfs_arc plugin: Support for FreeBSD has been added. Thanks to Xin Li
+ for his patch.
+
+2013-07-13, Version 5.3.1
+ * Documentation: Various fixes.
+ * Configuration: Fix error handling: Errors in included files were
+ ignored, causing configuration mistakes to go unnoticed.
+ * dns plugin: Don't abort when PCAP returns an error.
+ * modbus plugin: The reconnection strategy was improved, fixing a
+ segfault in the libmodbud library. Thanks to Stefan Nickl and
+ Fabien Wernli for their patches.
+ * mysql plugin: The notification about a newly running MySQL slave
+ thread has been fixed. Thanks to Joaquín Cuenca Abela for the patch.
+ * snmp plugin: A build issue has been fixed (C99 mixed declaration).
+ The end-of-tree check has been improved by Pierre-Yves Ritschard.
+ * threshold plugin: Handling of the "Interesting" configuration option
+ has been fixed. Thanks to Björn for the patch.
+ * write_riemann plugin: A memory leak has been fixed. Thanks to Dave

2013-04-09, Version 5.3.0
* collectd: The "Include" statements can now be limited to include
only matching files in a directory. Thanks to Sebastian Harl for his
Sensors in Macs running Mac OS X / Darwin: Temperature, fanspeed and
voltage sensors.
+ - aquaero
+ Various sensors in the Aquaero 5 watercooling board made by Aquacomputer.
+
- ascent
Statistics about Ascent, a free server for the game `World of Warcraft'.
- serial
RX and TX of serial interfaces. Linux only; needs root privileges.
+ - sigrok
+ Uses libsigrok as a backend, allowing any sigrok-supported device
+ to have its measurements fed to collectd. This includes multimeters,
+ sound level meters, thermometers, and much more.
+
- snmp
Read values from SNMP (Simple Network Management Protocol) enabled
network devices such as switches, routers, thermometers, rack monitoring
* A POSIX-threads (pthread) implementation.
Since gathering some statistics is slow (network connections, slow devices,
- etc) the collectd is parallelized. The POSIX threads interface is being
+ etc) collectd is parallelized. The POSIX threads interface is being
used and should be found in various implementations for hopefully all
platforms.
+ * aerotools-ng (optional)
+ Used by the `aquaero' plugin. Currently, the `libaquaero5' library, which
+ is used by the `aerotools-ng' toolkit, is not compiled as a shared object
+ nor does it feature an installation routine. Therefore, you need to point
+ collectd's configure script at the source directory of the `aerotools-ng'
+ project.
+ <https://github.com/lynix/aerotools-ng>
+
* CoreFoundation.framework and IOKit.framework (optional)
For compiling on Darwin in general and the `apple_sensors' plugin in
particular.
Used by the `memcachec' plugin to connect to a memcache daemon.
<http://tangent.org/552/libmemcached.html>
+ * libmnl (optional)
+ Used by the `netlink' plugin.
+ <http://www.netfilter.org/projects/libmnl/>
+
* libmodbus (optional)
Used by the “modbus” plugin to communicate with Modbus/TCP devices. The
“modbus” plugin works with version 2.0.3 of the library – due to frequent
Required for the “netapp” plugin.
This library is part of the “Manage ONTAP SDK” published by NetApp.
- * libnetlink (optional)
- Used, obviously, for the `netlink' plugin.
- <http://www.linuxfoundation.org/en/Net:Iproute2>
-
* libnetsnmp (optional)
For the `snmp' plugin.
<http://www.net-snmp.org/>
To read from `lm_sensors', see the `sensors' plugin.
<http://www.lm-sensors.org/>
+ * libsigrok (optional)
+ Used by the sigrok plugin. In addition, libsigrok depends on glib,
+ libzip, and optionally (depending on which drivers are enabled) on
+ libusb, libftdi and libudev.
+
* libstatgrab (optional)
Used by various plugins to collect statistics on systems other than Linux
and/or Solaris.

+#
+# q: What is this ?
+# a: A specfile for building RPM packages of current collectd releases, for
+# RHEL/CentOS versions 5 and 6. By default all the plugins which are
+# buildable based on the libraries available in the distribution + the
+# EPEL repository, will be built. Plugins depending on external libs will
+# be packaged in separate RPMs.
+#
+# q: And how can I do that ?
+# a: By following these instructions, using mock:
+#
+# - install and configure mock (https://fedoraproject.org/wiki/Projects/Mock)
+#
+# - enable the EPEL repository (http://dl.fedoraproject.org/pub/epel/) in the
+# configuration files for your target systems (/etc/mock/*.cfg).
+#
+# - copy this file in your ~/rpmbuild/SPECS/ directory
+#
+# - fetch the desired collectd release file from https://collectd.org/files/
+# and save it in your ~/rpmbuild/SOURCES/ directory
+#
+# - build the SRPM first:
+# mock -r centos-6-x86_64 --buildsrpm --spec ~/rpmbuild/SPECS/collectd.spec \
+# --sources ~/rpmbuild/SOURCES/
+#
+# - then build the RPMs:
+# mock -r centos-6-x86_64 --no-clean --rebuild \
+# /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm
+#
+# - you can also optionally enable/disable plugins which are disabled/enabled
+# by default:
+# mock -r centos-6-x86_64 --no-clean --without=java --with=oracle --rebuild \
+# /var/lib/mock/centos-6-x86_64/result/collectd-X.Y.Z-NN.src.rpm

collectd.conf - Configuration for the system statistics collection daemon B<collectd>
Include "/etc/collectd.d/*.conf"
+Starting with version 5.3, this may also be a block in which further options
+affecting the behavior of B<Include> may be specified. The following option is
+currently allowed:
+
+ <Include "/etc/collectd.d">
+ Filter "*.conf"
+ </Include>
+
+=over 4
+
+=item B<Filter> I<pattern>
+
If the C<fnmatch> function is available on your system, a shell-like wildcard
I<pattern> may be specified to filter which files to include. This may be used
in combination with recursively including a directory to easily be able to
arbitrarily mix configuration files and other documents (e.g. README files).
-The following statement is similar to the example above but includes all files
+The given example is similar to the first example above but includes all files
matching C<*.conf> in any subdirectory of C</etc/collectd.d>:
Include "/etc/collectd.d" "*.conf"
+=back
+
If more than one files are included by a single B<Include> option, the files
will be included in lexicographical order (as defined by the C<strcmp>
function). Thus, you can e.E<nbsp>g. use numbered prefixes to specify the
default value is B<5>, but you may want to increase this if you have more than
five plugins that may take relatively long to write to.
+=item B<WriteQueueLimitHigh> I<HighNum>
+
+=item B<WriteQueueLimitLow> I<LowNum>
+
+Metrics are read by the I<read threads> and then put into a queue to be handled
+by the I<write threads>. If one of the I<write plugins> is slow (e.g. network
+timeouts, I/O saturation of the disk) this queue will grow. In order to avoid
+running into memory issues in such a case, you can limit the size of this
+queue.
+
+By default, there is no limit and memory may grow indefinitely. This is most
+likely not an issue for clients, i.e. instances that only handle the local
+metrics. For servers it is recommended to set this to a non-zero value, though.
+
+You can set the limits using B<WriteQueueLimitHigh> and B<WriteQueueLimitLow>.
+Each of them takes a numerical argument which is the number of metrics in the
+queue. If there are I<HighNum> metrics in the queue, any new metrics I<will> be
+dropped. If there are less than I<LowNum> metrics in the queue, all new metrics
+I<will> be enqueued. If the number of metrics currently in the queue is between
+I<LowNum> and I<HighNum>, the metric is dropped with a probability that is
+proportional to the number of metrics in the queue (i.e. it increases linearly
+until it reaches 100%.)
+
+If B<WriteQueueLimitHigh> is set to non-zero and B<WriteQueueLimitLow> is
+unset, the latter will default to half of B<WriteQueueLimitHigh>.
+
+If you do not want to randomly drop values when the queue size is between
+I<LowNum> and I<HighNum>, set If B<WriteQueueLimitHigh> and
+B<WriteQueueLimitLow> to same value.

+
+The I<sigrok> logging level to pass on to the I<collectd> log, as a number
+between B<0> and B<5> (inclusive). These levels correspond to C<None>,
+C<Errors>, C<Warnings>, C<Informational>, C<Debug >and C<Spew>, respectively.
+The default is B<2> (C<Warnings>). The I<sigrok> log messages, regardless of
+their level, are always submitted to I<collectd> at its INFO log level.
+
+=item E<lt>B<Device> I<Name>E<gt>
+
+A sigrok-supported device, uniquely identified by this section's options. The
+I<Name> is passed to I<collectd> as the I<plugin instance>.
+
+=item B<Driver> I<DriverName>
+
+The sigrok driver to use for this device.
+
+=item B<Conn> I<ConnectionSpec>
+
+If the device cannot be auto-discovered, or more than one might be discovered
+by the driver, I<ConnectionSpec> specifies the connection string to the device.
+It can be of the form of a device path (e.g.E<nbsp>C</dev/ttyUSB2>), or, in
+case of a non-serial USB-connected device, the USB I<VendorID>B<.>I<ProductID>
+separated by a period (e.g.E<nbsp>C<0403.6001>). A USB device can also be
+specified as I<Bus>B<.>I<Address> (e.g.E<nbsp>C<1.41>).
+
+=item B<SerialComm> I<SerialSpec>
+
+For serial devices with non-standard port settings, this option can be used
+to specify them in a form understood by I<sigrok>, e.g.E<nbsp>C<9600/8n1>.
+This should not be necessary; drivers know how to communicate with devices they
+support.
+
+=item B<MinimumInterval> I<Seconds>
+
+Specifies the minimum time between measurement dispatches to I<collectd>, in
+seconds. Since some I<sigrok> supported devices can acquire measurements many
+times per second, it may be necessary to throttle these. For example, the
+I<RRD plugin> cannot process writes more than once per second.
+
+The default B<MinimumInterval> is B<0>, meaning measurements received from the
+device are always dispatched to I<collectd>. When throttled, unused
+measurements are discarded.

+=head2 Plugin C<statsd>
+
+The I<statsd plugin> listens to a UDP socket, reads "events" in the statsd

+periodically.
+
+The plugin implements the I<Counter>, I<Timer>, I<Gauge> and I<Set> types which
+are dispatched as the I<collectd> types C<derive>, C<latency>, C<gauge> and
+C<objects> respectively.
+
+The following configuration options are valid:
+

+
+Bind to the hostname / address I<Host>. By default, the plugin will bind to the
+"any" address, i.e. accept packets sent to any of the hosts addresses.
+
+=item B<Port> I<Port>
+
+UDP port to listen to. This can be either a service name or a port number.
+Defaults to C<8125>.

+
+=item B<DeleteTimers> B<false>|B<true>
+
+=item B<DeleteGauges> B<false>|B<true>
+
+=item B<DeleteSets> B<false>|B<true>
+
+These options control what happens if metrics are not updated in an interval.
+If set to B<False>, the default, metrics are dispatched unchanged, i.e. the
+rate of counters and size of sets will be zero, timers report C<NaN> and gauges
+are unchanged. If set to B<True>, the such metrics are not dispatched and
+removed from the internal cache.
+
+=item B<TimerPercentile> I<Percent>
+
+Calculate and dispatch the configured percentile, i.e. compute the latency, so
+that I<Percent> of all reported timers are smaller than or equal to the
+computed latency. This is useful for cutting off the long tail latency, as it's
+often done in I<Service Level Agreements> (SLAs).
+
+If not specified, no percentile is calculated / dispatched.
