user global HighGlobalCPU
event manager applet ReportHighCPU
event resource policy “HighGlobalCPU”
action 1.0 cli command “show process cpu sorted 1min | exclude 0.00”
action 1.1 info type routername
action 2.0 mail server “<exchangeserver>” to “administrator@<domainname>” from “info_Cisco_Router<type>@<domainname>” subject “CPU @ $_resource_current_value” body “$_cli_result”
So when the router has a high cpu usage. you will get notified with an email like below.
