## Using ILOM to Monitor the Host

This section describes the sensors and indicators that can be accessed through the ILOM.

Sensors report physical information about the server, including voltages, temperatures, fan speeds, and installation and removal of components.

Indicators report important server conditions.

All sensors and indicators are IPMI-compliant.
