Viewing CPU Utilization Reports
The CPU Utilization report summarizes the percentage of the CPU used within the time period specified.
Typically, the Core operates on approximately 30 to 40 percent of total CPU capacity during nonpeak hours and approximately 60 to 70 percent capacity during peak hours. No single Core CPU usage should exceed 90 percent.
What This Report Tells You
The CPU Utilization report answers these questions:
• How much of the CPU is being used?
• What is the average and peak percentage of the CPU being used?
About Report Graphs
In bar-graph and line-graph reports, the x-axis (or tick mark) plots time, according to the interval you select. The y-axis plots the metric of interest, such as gigabytes of bandwidth, percent of data reduction, connection counts, and so on.
The right margin of the graph points to the value on the y-axis (for example, the percent) that is the average value for the time period selected.
To view the CPU Utilization report
1. Choose Reports > Diagnostics: CPU Utilization to display the CPU Utilization page.
2. Customize the report using the controls described in this table.
Control | Description |
Period settings | Click 5m (last five minutes), 1h (last hour), 1d (last day), 1w (last week), or All (last month). For a custom time period, specify the start and end times in the fields immediately below these settings. Use the following format: yyyy/mm/dd hh:mm:ss. You can also use the adjustable slider at the bottom of the graph. |
Display Mode | Select a display mode from the drop-down list: • Brief - Displays the CPU utilization percentage of all cores as a system average. • Detailed - Displays the CPU utilization percentages for individual cores. The individual cores appear with a number and a color in the data series. To hide or display a core in the plot area, select or clear the check box next to the core name. |
Cores | Displays which cores are available for detailed side-by-side comparison in the graph. Note: This option is only available if you are in Detailed display mode. |
