Viewing Appliance CPU Utilization Reports
The CPU Utilization report summarizes the percentage of the CPU used on the SCC machine within the time period specified. You can display individual cores or an overall average, or both.
For details about operating report controls, see Overview.
General Usage Guidelines
Typically, a SteelHead appliance operates on approximately 30 to 40 percent CPU capacity during nonpeak hours and approximately 60-70 percent capacity during peak hours. No single SteelHead 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
Use the mouse to hover over a specific data point to see the y values and exact time stamp were in relation to the peaks.
The CPU Utilization and Memory Paging report pages expect the SCC to receive data from any SteelHead every 5 minutes. If the report displays some discontinuities in the graph, it is because the two data points (5 minutes after and 10 minutes after the previous data sample) are missing from the SCC's perspective.
For detailed information about data grouping, see Data Grouping.
