Centos Check CPU Usage

This procedure is used to check the CPU usage.
Since this is a standard distribution of linux, customers can use other available commands.

Check CPU usage

From the web interface you can see the CPU usage:

 Hosts -> Status -> Select Host -> Processor Usage tab

From the SSH access, here are the available commands.
With the top command you can see the total CPU usage (and Memory usage) of the host:
