AWS EC2: Instance CPU Utilization
This check monitors the percentage of allocated EC2 compute units that are
currently in use on the AWS EC2 instance.
To make this check work you have to configure the related
Amazon Web Services (AWS).
You can configure upper levels for
CRIT (default: 90.0, 95.0).
The service goes
CRIT if the CPU utilization exceeds these levels.
One service is created if all required metrics (CPUUtilization) are given.
