Process/CPU Priority Distribution (PRIDIST)
Process/CPU Priority Distribution (PRIDIST)
This 74-column chart shows utilization of each CPU at each active process priority.
Owing to limited space on the page, it shows utilization in integer tenths of percent.
This chart uses the GLOBINFO, CPU, and PROCESS entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
The chart is sorted in descending process priority order.
