IPS 4240 High CPU troubleshooting

[fernandoaguirre]

Hi,

I have a IPS 4240 with software version 6.2(1)E3 running. Lately I've been having problems with low performance on this equipment due to high cpu utilization going to 100%. I need some troubleshooting tips or commands I can use to determine what is causing this high cpu usage. Please help with some show or debug commands I could use!!

Regards,

Here are some commands you can use :

"show statistics host"

"show statistics virtual-sensor | incl Load". This should give an indication of the current inspection load. If the traffic load is not heavy then this number should go down. If you have a service account you can also do a "top" in the shell to find out which process is hogging the CPU.
