ENTITY-SENSOR-MIB adds support for physical sensors
of networking equipment beyond what ENTITY-MIB defines. Use this MIB in tandem with the ENTITY-MIB to monitor
the operational status of the physical components of a system (for
example, fans and temperature sensors). For example, to troubleshoot
issues that might result from environmental conditions, you can map
the entity indexes from the ENTITY-MIB (entPhysicalDescr object)
to operational status values (entPhysSensorOperStatus object) in
the ENTITY-SENSOR-MIB. In the following example, all the fans and temperature
sensors for a PA-3020 firewall are working:
The same OID might refer to different sensors on different
platforms. Use the ENTITY-MIB for the targeted platform to match
the value to the description.
Palo Alto Networks firewalls, Panorama, and WF-500 appliances
support only portions of the entPhySensorTable group. The supported
portions vary by platform and include only thermal (temperature
in Celsius) and fan (in RPM) sensors.
