Viewing CPU Utilization Reports
The Reports > Diagnostics > CPU Utilization report summarizes the percentage of the CPU used within the time period specified.
Typically, a Mobile Controller operates on approximately 5 to 10 percent CPU capacity during nonpeak hours and approximately 25 to 30 percent capacity during peak hours. No single Mobile Controller CPU usage should exceed 90 percent.
What This Report Tells You
The CPU Utilization report answers the following 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 GBs of bandwidth, percent (%) of data reduction, connection counts, and the like.
Drag your cursor over an area of interest to zoom. Click Reset Zoom to return to normal view. To display only one data type (for example, WAN, LAN) click the name of the data in the graph legend.
Pie chart graphs do not indicate peaks or averages. Pie chart graphs represent the aggregate for the time period selected.
