This article showcases the SNMP OIDs used to monitor power usage (Max capacity, Actual usage and power remainder, FPC max and used power) on EX92xy and QFX10008.
On EX92xy and QFX10008 switches, SNMP OIDs used to monitor power usage were not displaying the correct information in earlier Junos releases.
Engineering implemented SNMP OIDs to monitor power usage on EX92xy (PR 1715664) and on QFX10008 (PR 1715050).
Consider the example below taken on a EX9208 chassis that shows the SNMP OIDs used to monitor power usage (Max capacity, Actual usage and power remainder, FPC max and used power).
