Processor trend graphs

The Performance Monitoring home page includes trend graphs that show processor utilization data that is plotted against a default time interval of 4 hours.

By default, the trend graph shows server level data; however, you can change the view to display aggregated level data. To switch from one view to another view, click More Graphs and choose Server Level Utilization or Aggregated Level Utilization.

Processor trend graph: Server Level Utilization view

The Server Level Utilization view indicates the number of processors that the server is using at the times indicated along the horizontal axis. The lower shaded area represents the total number of activated physical processors on the server, and the upper shaded area indicates how many more processors are available for activation. The line shows how the total processor usage on the physical server varies over the selected time period, in comparison with the available processor capacity.

Processor trend graph: Aggregated Level Utilization view

The Aggregated Level Utilization view shows the total number of processors that the server is using. You can compare whether the processors are being used by the system firmware, Virtual I/O Servers, or client partitions by viewing the shading for each processor.
