Foundry's CPU utilization OID 1.3.6.1.4.1.1991.1.1.2.11.1.1.4
There is a catch - Foundry reports utilization in 1/100 of the procent, so number 820 means 8.2%. I have Fondry ServerIron 450 with 1 management CPU and 3 CPUs on Web Switching module and wanted to know 5 min. average for management CPU:
