What is fnSysCpuUsage?
Reports the device's CPU utilization at the moment it's polled, as a percentage. An admin graphs this over time to spot sustained high CPU that might indicate an attack, a misconfigured policy doing excessive inspection, or a device nearing its performance ceiling.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.12356.1.8 snmpwalk -v2c -c public <target> FORTINET-300-MIB::fnSysCpuUsage
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.12356.1.8.1 snmpget -v2c -c public <target> FORTINET-300-MIB::fnSysCpuUsage.1
