Wireless CPU Utilization
Wireless CPU Utilization report reveals the top n access points using the largest fraction of the overall CPU processor time during the selected interval.
- . Device name or IP Address and the CPU identifier.
- . Processor index (if device is multi processor or many core).
- . Minimum observed average utilization.
- . Highest observed average utilization.
- . Overall average utilization for the selected interval.

Purpose
|
Show Top n Items
|
Limit items to the samples with the highest (or lowest) utilization.
|
Threshold Type
|
Switch between minimum or maximum mode for cutoff values for the ranked list.
- At or Over. Show peak usage period. (Utilization percentage equal to or greater than Threshold.)
- At or Under. Show usage periods where resources are unused or possibly down. (Utilization percentage equal to or less than Threshold.)
|
Threshold (percent)
|
Baseline value used to trim ranked device list based on peak or subpeak capacity when returning the Top n.

- Gauge charts. Available when you select a Date Range of .
- Time series. Available when you select a Date Range interval (, for example).
- Line/Area. Scatter graph that connects adjacent measurements with straight lines.
- Spline/Area Spline. Choose a graph with a smoothed appearance where adjacent samples exhibit a gradual slope.

Chart Options
|
- Legend, Grid Lines, Range Selector. Include legend, grid lines, and range selector for readability.
- Trend Lines. Present data with a smoothed average to show trend.

: Trend lines represent a moving average that can be compared with line and area graphs to reveal peak and sub peak intervals, periods of burstiness, latency, and interruption.
: This report only returns Wireless CPU Utilization metrics for devices that already have the appropriate WMI or SNMP credentials. For more information, see Using Credentials.
