CPU Page
The CPU page contains several charts.
To open the network page

-
Click Activity Summary | CPU.
Charts on the CPU page
Notes:
- Every chart has a legend (list of symbols) to its right that describes the various series (line graphs) on the chart.
- Click an item in the legend to highlight its series (line) in the chart. Click a second time to return the series to its normal appearance.
- Move the mouse pointer over an item in the legend to view the current value for that series within the chart.
| Chart | Description |
|---|---|
| Total CPU Usage | The total CPU utilization for all processors on the Unix host. |
| CPU Usage by Processor | The CPU utilization for each processor on the Unix host. Each processor is represented by a single line on the chart, and by an item in the legend at the top right of the chart. |
| Run Queues | The number of threads (program execution units) that are waiting to run on the Unix host. |
| Context Switching |
The rate at which the Unix host has been processing context switches. A context switch occurs when a processor switches from one thread to another. Context switches occur when a running thread voluntarily relinquishes the processor, is pre-empted by a higher priority ready thread, or switches between user-mode and privileged (kernel) mode to invoke a system service. |
