Use PAN-ENTITY-EXT-MIB.my in tandem with the ENTITY-MIB to monitor power usage for the physical components of a PA-7000 Series or PA-5450 firewall (for example, fan trays, and power supplies), which are the only two Palo Alto Networks firewalls that support this MIB. For example, when troubleshooting log forwarding issues, you might want to check the power usage of the log processing cards (LPCs): you can map the LPC indexes from the ENTITY-MIB (entPhysicalDescr object) to values in the PAN-ENTITY-EXT-MIB (panEntryFRUModelPowerUsed object).
