Processor Utilization, by the Hour

Hourly Processor Utilization Graph.
The Processor Utilization by Hour graph shows the hourly processor utilization average during
the last 30-day period. This allows you to see how the workload changes during a day.
The symbols used on this graph are explained as follows:

The forward slash (green) shows system usage (Jobtype = S).

The crosshatch (blue) shows interactive usage (Jobtype = I).

The backward slash (red) shows the batch usage (Jobtype = B). The height of this line
shows the total processor utilization of all priorities.

The time indication, 08 for example, represents the time range 08:00 through 08:59.

The black line shows the busiest hour of interactive peak utilization for that hour during
the last 30-day period, expressed as a percentage of the total processor capability. It is
likely that when this value is high, degraded response times were experienced during that
hour on at least one day of the period.

The blue line shows the busiest hour of total peak processor utilization for that hour
during the last 30-day period. It is likely that your system experienced a degradation of
throughput some day during the period if this percentage is high during a long period.

The red line shows the interactive limit that is defined in your system, set by the
interactive feature installed, or set by the partition definition or the software Edition.
