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.
RFC 3433 defines the ENTITY-SENSOR-MIB.
