Description This article describes the recommended SNMP interval inquiries.
Scope FortiGate.
Solution

A short interval of inquiring SNMP can cause high CPU consumption on FortiGate:

 

diagnose sys top 2 99
Run Time: 3 days, 14 hours and 36 minutes
2U, 0N, 6S, 92I, 0WA, 0HI, 0SI, 0ST; 16063T, 9472F
           snmpd 277 R 96.5 0.2 <<<<<<<
            iked 275 S 3.0 0.5

Run Time: 3 days, 14 hours and 36 minutes
2U, 0N, 9S, 89I, 0WA, 0HI, 0SI, 0ST; 16063T, 9473F
           snmpd 277 R 99.5 0.2 <<<<<<<
         miglogd 315 S 3.4 0.2
            iked 275 S 2.9 0.5


The recommendation is to configure a 30-second interval for SNMP queries.


If necessary, it can be decreased to a 10-second interval while monitoring and checking whether the CPU utilization of the FortiGate system is okay.
