Monitoring Per-Process CPU Usage
You can monitor the processes that run on the CPU. You can obtain information about the percentage of
CPU that is used by a certain process. CPU usage statistics are sorted in descending order to display the
highest consumer at the top. Also included is information about the load on the CPU per process, at 5
seconds, 1 minute, and 5 minutes before the log time. This information is updated automatically every
5 seconds to provide real-time statistics. In ASDM it is updated every 30 seconds.
