high dataplane cpu utilization

UMWL — Fri, 30 Oct 2015 14:22:41 GMT

Hi,

I have PA-2020 which has high dataplane cpu utilization. It is stuck at 100% during business hours. It drops to 25% after work. I suspect too much traffic but is there an easy way to check what sessions/applications are the most cpu intensive? Maybe from CLI?

Hello,

Try the command, show running resource-monitor. That may get you what you are looking for.

I know the 2020's didnt have a seperate management plane so if you are running a service such as netflow, it may cause it to be super high.

Hope this helps..
