What you are seeing here is

What you are seeing here is the output for the last 72 hours, the * symbols mean the maximum cpu utilization that it reached during the hour specified, it could be even just a second that it got there, the # symbols mean the average that it had over the full hour, lets take in example hour 5, you see that maximum cpu reached was 70%, however that does not really mean high cpu since the average was 10% which is really common. In the last 72 hours your average was 10%, with some common picks.
