CPU notifications

[charleswindon]

I am trying to figure out how to have an ASA 5520 send out an email notification when the CPU utilization exceeds 80%.  Is there a way to do this, or would I need other utilities to provide this informaiton.

Thanks,

The ASA generates a syslog for that:

Error Message    %ASA-2-321006: System memory usage reached utilization %

Explanation    The system memory usage has reached 80 percent or more and remains at this level for five minutes.

•utilization %—The percentage of CPU being used

Recommended Action    If this message occurs periodically, you can ignore it. If it repeats frequently, check the output of the show memory command and verify the memory usage. If it is high, contact the Cisco TAC.

you can create a logging list and have the ASA send it by email:
