If there is excessive system CPU utilization on your system, use the Real-time displays to monitor system performance. For more information, see the Performance Manager Administrator Guide.
When a period of excessive system time occurs, run System PC collections.
Generate and examine the report to determine who is using the CPU, at what access modes, and for what reason. The following figure is an example of a System PC Analysis report segment. The following report shows processor usage by process, the number of PC samples, and the total CPU and system time for each process:
