Viewing SCC CPU Utilization Reports
The CPU Utilization report summarizes the percentage of the CPU used within the time period specified.
Typically, a SteelHead operates on approximately 30 to 40 percent CPU capacity during nonpeak hours and approximately 60 to 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 peaks.
About Report Data
The Riverbed system reports for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled.
For detailed information about data grouping, see Data Grouping.
