<title>IPMI agent</title>
<para>This agent is responsible for collecting IPMI sensor data and Intel Node Manager
data on individual compute nodes within an OpenStack deployment. This
agent requires IPMI capable node with <application>ipmitool</application> installed, which
is a common utility for IPMI control on various Linux distributions.</para>
<para>An IPMI agent instance could be installed on each and every compute node
with IPMI support, except that the node is managed by Bare metal module for OpenStack
and the <option>conductor.send_sensor_data</option> option is set to <literal>true</literal>
in the Bare metal module for OpenStack.
It is no harm to install this agent on compute node without IPMI or Intel Node
Manager support, as the agent checks for the hardware and if none is available, returns empty data.
But it is suggested that you install IPMI agent only on IPMI capable node for performance reason.
</para>
<para>Just like the central agent, this component also does not need a direct database
access. The samples are sent via AMQP to the collector.

Ironic Hardware IPMI Sensor Data section</link> in the <citetitle>Telemetery Measurements Reference</citetitle>.</para>
<note>
<para>Do not deploy both IPMI agent and Bare metal module for OpenStack on
one compute node. If <option>conductor.send_sensor_data</option> set, this
misconfiguration causes duplicated IPMI sensor samples.
