fnTrapCpuThreshold
Module: FORTINET-CORE-MIB
OID (symbolic): FORTINET-CORE-MIB::fnTrapCpuThreshold
OID (numeric): 1.3.6.1.4.1.12356.100.1.3.0.101
Node type: NOTIFICATION-TYPE
Description:
Indicates that the CPU usage has exceeded the configured threshold.
What is fnTrapCpuThreshold?
This notification fires when a Fortinet FortiGate security appliance's CPU utilization exceeds an administratively configured threshold. The alert includes the device serial number and hostname to identify which device is under load. Operators react to this by investigating CPU-intensive processes and either optimizing policies or upgrading hardware to prevent performance degradation.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' FORTINET-CORE-MIB::fnTrapCpuThreshold snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.12356.100.1.3.0.101
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
