Explanation

CPU Diagram

CPU Diagram

Use to show the following for each logical system or node for which there is data:

  • The capacity and utilization of all physical systems or nodes
  • A breakdown of the utilization into logical system or node components
  • Within each logical system/node, a breakdown of utilization by workload category or workload

Management Time

Management Time

Use to show the system management time across the selected intervals.

Partition Diagram

Partition Diagram
