Provides access to details about statistics that are available for the selectedController CPU. No statistics are displayed on this page; statistics are only available by selecting ActionsCPU Statistics.

Valid choices:

Controller: Identifies the selected Controller.

To generate statistics about a Controller CPU, select a Controller and then select Actions > Controller CPU Real Time Statistics. Click Add Graph and select a statistic (you can review the following list for details).

The two choices are:

Percent Time in Kernel: Percentage of CPU utilization that occurred while executing commands at the system level. The scale is 0 to 100 percent.

Total Percent Time Busy: Percentage of time the CPU was busy on theController. The scale is 0 to 100 percent.

Theses measurement can be used to identify trends in Controller CPU usage that can cause performance issues. For example, if the Total Percent Time Busy for the CPU exceeds 90%, there can be I/O bottleneck at the Controller. These statistics are generally requested by Oracle Customer Support to help resolve potential system load issues, identity system capacity issues, or application issues.
