-All the plugins above are available on the collectd master, except for the
-Gnocchi and Aodh plugins as they are Python-based plugins and only C plugins
-are accepted by the collectd community. The Gnocchi and Aodh plugins live in
-the OpenStack repositories.
-
-Other plugins existing as a pull request into collectd master:
+* *virt*: A read plugin that uses virtualization API *libvirt* to gather
+ statistics about virtualized guests on a system directly from the hypervisor,
+ without a need to install collectd instance on the guest.
* *SNMP Agent*: A write plugin that will act as a AgentX subagent that receives
and handles queries from SNMP master agent and returns the data collected
from collectd and translates requested values from collectd's internal format
to SNMP format. Supports SNMP: get, getnext and walk requests.

**Plugins included in the Danube release:**
Sample configuration files can be found in '/opt/collectd/etc/collectd.conf.d'
.. note::
- - If you plan on using the Exec plugin, the plugin requires non-root
- user to execute scripts. By default, `collectd_exec` user is used. Barometer
- scripts do *not* create this user. It needs to be manually added or exec plugin
- configuration has to be changed to use other, existing user before starting
- collectd service.
-
- - If you don't want to use one of the Barometer plugins, simply remove the
- sample config file from '/opt/collectd/etc/collectd.conf.d'

+ If you are using any Open vSwitch plugins you need to run:

+
+ $ sudo systemctl status collectd

+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.
+
Intel RDT Plugin
^^^^^^^^^^^^^^^^
Repo: https://github.com/collectd/collectd
$ sudo modprobe ipmi_devintf
$ sudo modprobe ipmi_si
-**Note**: If HW supports IPMI, the ``/dev/ipmi0`` character device will be
-created.

Clone and install the collectd IPMI plugin:
SELEnabled true # only feat_ipmi_events branch supports this
</Plugin>
-**Note**: By default, IPMI plugin will read all available analog sensor values,
-dispatch the values to collectd and send SEL notifications.

Dependencies: mcelog
-Start by installing mcelog. Note: The kernel has to have CONFIG_X86_MCE
-enabled. For 32bit kernels you need at least a 2.6,30 kernel.

On ubuntu:
This will inject different classes of errors and check that the mcelog triggers
runs. There will be some kernel messages about page offlining attempts. The

**mce-inject:**
A utility to inject corrected, uncorrected and fatal machine check exceptions
$ ./mce-inject < test/corrected
-**Note: the uncorrected and fatal scripts under test will cause a platform reset.
-Only the fatal script generates the memory errors**. In order to quickly
-emulate uncorrected memory errors and avoid host reboot following test errors

+OVS PMD stats
+^^^^^^^^^^^^^^
+Repo: https://gerrit.opnfv.org/gerrit/barometer
+
+Prequistes:
+1. Open vSwitch dependencies are installed.
+2. Open vSwitch service is running.
+3. Ovsdb-server manager is configured.
+You can refer `Open vSwitch Plugins`_ section above for each one of them.
+
+OVS PMD stats application is run through the exec plugin.
+
+To configure the OVS PMD stats application you need to modify the exec plugin configuration
+to include:
+
+.. code:: bash
+
+ <LoadPlugin exec>
+ Interval 1
+ </LoadPlugin
+ <Plugin exec>
+ Exec "user:group" "<path to ovs_pmd_stat.sh>"
+ #NotificationExec "nobody" "/usr/lib/collectd/notify.sh"
+ </Plugin>
+
+.. note:: Exec plugin configuration has to be changed to use appropriate user before starting collectd service.
+
+ovs_pmd_stat.sh calls the script for OVS PMD stats application with its argument:
+
+.. code:: bash
+
+ sudo python /usr/local/src/ovs_pmd_stats.py" "--socket-pid-file"
+ "/var/run/openvswitch/ovs-vswitchd.pid"
