Detect High CPU on a Cisco Switch

Recently, I have had an issue on a Core Switch. This switch was running at 80% of CPU for 3 days. The CPU was not monitored and we have not received a syslog message on our server.
Also, I have decided to use the following command (on 4k5) in order to trigger a syslog alert in case of High CPU:

process cpu threshold type total rising 60 interval 20

This command trigger a syslog alert if the CPU exceeds 60 percent for a period of 20 seconds.
