+Intel PMU Plugin
+^^^^^^^^^^^^^^^^
+Repo: https://github.com/collectd/collectd
+
+Branch: master
+
+Dependencies:
+
+ * PMU tools (jevents library) https://github.com/andikleen/pmu-tools
+
+To be suitable for use in collectd plugin shared library *libjevents* should be
+compiled as position-independent code. To do this add the following line to
+*pmu-tools/jevents/Makefile*:
+
+.. code:: bash
+
+ CFLAGS += -fPIC
+
+Building and installing *jevents* library:
+
+.. code:: bash
+
+ $ git clone https://github.com/andikleen/pmu-tools.git
+ $ cd pmu-tools/jevents/
+ $ make
+ $ sudo make install
+
+Building and installing collectd:
+
+.. code:: bash
+
+ $ git clone https://github.com/collectd/collectd.git
+ $ cd collectd
+ $ ./build.sh
+ $ ./configure --enable-syslog --enable-logfile --with-libjevents=/usr/local --enable-debug
+ $ make
+ $ sudo make install
+
+This will install collectd to /opt/collectd
+The collectd configuration file can be found at /opt/collectd/etc
+To configure the PMU plugin you need to modify the configuration file to
+include:
+
+.. code:: bash
+
+ <LoadPlugin intel_pmu>
+ Interval 1
+ </LoadPlugin>
+ <Plugin "intel_pmu">
+ ReportHardwareCacheEvents true
+ ReportKernelPMUEvents true
+ ReportSoftwareEvents true
+ </Plugin>
+
+For more information on the plugin parameters, please see:
+https://github.com/collectd/collectd/blob/master/src/collectd.conf.pod
+
+.. note::
+
+ The plugin opens file descriptors whose quantity depends on number of
+ monitored CPUs and number of monitored counters. Depending on configuration,
+ it might be required to increase the limit on the number of open file
+ descriptors allowed. This can be done using 'ulimit -n' command. If collectd
+ is executed as a service 'LimitNOFILE=' directive should be defined in
+ [Service] section of *collectd.service* file.
