Considerations

The options in the shift and day flags are all available to control the scope of this report.
If SRB time is zero in the data, only total CPU time is shown. The non-z/OS format is used for the report. Also no service units are shown.
If there are no wait records in the data, the Overall CPU Utilization Rate is very close to 100% (which might look nice but is incorrect).

Multiprogramming factor is calculated using active time on this report; however, the other reports use elapsed time.

System Overhead Time represents the difference between time for the measured interval and the total time accounted. An excessively high System Overhead is the result of missing SMF data. This can be caused by long running steps that complete in the measured time interval, inflating the measured time value.
