Interpret CPU Mode Statistics

The CPU mode statistics follow the pool statistics for each node in a cluster system. To display only the CPU mode statistics section of the Performance Evaluation Report, use the qualifier:

/INCLUDE=MODE_STATISTICS

To disable the CPU mode statistics display from the report, use the qualifier:

/INCLUDE=NOMODE_STATISTICS

The following example shows the CPU mode statistics section of the Performance Evaluation report:

  | The following table gives the average percent of time in each of the   |
  | various CPU modes for each active processor in the local node.         |
  | "Samples" is the record count contributing to the summary line.        |

The following statements are keyed to the previous example:

1. Physical processor identification
2. Percentage of time in kernel mode for this physical processor
3. Percentage of time in executive mode for this physical processor
4. Percentage of time in supervisor mode for this physical processor
5. Percentage of time in user mode for this physical processor
6. Percentage of time in interrupt stack for this physical processor
7. Percentage of time in compatibility mode for this physical processor
8. Percentage of time in null mode for this physical processor
9. Percentage of time in multiprocessor synchronization mode for this physical processor
10. Number of Performance Manager data records contributing to the above statistics
