Open vSwitch PMD stats application.
Collectd capabilities and usage
-------------------------------------
+-------------------------------
.. Describe the specific capabilities and usage for <XYZ> feature.
.. Provide enough information that a user will be able to operate the feature on a deployed scenario.
By default, `collectd_exec` user is used in the exec.conf provided in the sample
configurations directory under src/collectd in the Barometer repo. These scripts *DO NOT* create this user.
You need to create this user or modify the configuration in the sample configurations directory
- under src/collectd to use another existing non root user before running build_base_machine.sh.

.. note::
If you are using any Open vSwitch plugins you need to run:
-.. code:: bash

.. note:: DPDK statistics plugin requires DPDK version 16.04 or later.
If you set XDG_CACHE_HOME to anything other than the variable above - you will need to modify
the path for the EventList configuration.
-Use "Cores" option to monitor metrics only for configured cores. If an empty string is provided
+Use ``Cores`` option to monitor metrics only for configured cores. If an empty string is provided
as value for this field default cores configuration is applied - that is all available cores
are monitored separately. To limit monitoring to cores 0-7 set the option as shown below:

The IPMI plugin is already implemented in the latest collectd and sensors
like temperature, voltage, fanspeed, current are already supported there.

Start by installing mcelog.
* Check the MCE statistic: mcelog --client. Check the mcelog log for injected error details: less /var/log/mcelog.
