The dia command show 5% CPU usage only

Hello

The CPU spikes are occasional. Sometimes peaks reach 100% for no reason.

Any advice suggestion will greatly appreciated.

Thanks,

I donot have a FortiWeb, but i assume the CPU spike may cause by the automatic fortiguard update.

You can change the update time to off-hour to lower the impact of your traffic.

Disable the Auto Learn on your Policies...

Hello

How can I check if it's about automatic fortiguard update or Auto Learn on your Policies as you say?

What is the process that is responsible for each of these functions?

Thanks,
