Performance

The Wireless Performance page displays Bandwidth, Client Count, Rogue Count, Received Signal Strength Indicator, CPU Utilization, Signal to Noise Ratio, and Memory Utilization data for wireless infrastructure devices connected to your network. By default, data for all devices is shown. You can filter the performance data that is displayed by selecting specific wireless devices or network groups from the navigation tree on the left side of the page. For additional information on each report, see the following:

• Bandwidth Report
• Client Count Report
• Rogue Count Report
• Received Signal Strength Indicator Report
• CPU Utilization Report
• Signal to Noise Ratio Report
• Memory Utilization Report

To select the number of devices displayed on a graph or in the table:

Select a number from the Max items list at the top of the report.

To configure tabular and graphical display options:

Click the applicable icon to display device information in the desired format. Click for tabular, for stacked area graph, or for line graph.

Note: Bandwidth, Client Count, and Rogue Count data support stacked area graphing. If Current is selected as the reporting interval, stacked area graphs cannot be generated for any performance data. Additionally, if Current is selected, clicking the line graph button generates a pie chart with each client, SSID, or access point (depending on your specified grouping) depicted as a different color wedge.

The arrangement of graphs and tables on the Performance page is configurable. You can specify which reports appear on the Performance page as well as in what position.

To configure the layout of the Performance page:

1. Click Configure Layout. The Configure Layout dialog appears.
2. Click to select the check box to the left of any reports you no longer want to display on the Performance page. As items are deselected, they automatically move down the list within the dialog leaving selected items at the top.
3. Of the reports that remain selected, if desired, click and drag report titles within the dialog to reorder the list. The position map shown within the dialog represents how your configured reports listing appears on the Performance Page.
4. Click OK to save configuration changes.

Note: Following initial device discovery, as initial polling occurs and data returns, it may take a few moments for information to display.

Clicking an icon to the left of a device displayed in any tabular report launches a dialog containing detailed device information.

• represents a lightweight access point.
• represents an autonomous access point.
• represents a WLC.

Specific dialog content is dependant upon device type and identical to detailed device information displayed when you click on an icon on the Wireless Map page. For descriptions of each device type-specific dialog, see Map.

Note: To see icons in the Bandwidth report, select grouping by AP.

Clicking the icon at the upper right corner or clicking anywhere on a report displayed on the Performance page causes that report to open in a full page view. When a report is viewed in this manner, you still have the ability to switch between tabular and graphical displays, modify the reporting interval, change the grouping, select other scans and devices to display, and increase or decrease the maximum number of items displayed on the report. Additionally, from any full page view, clicking Axis Scaling launches a dialog you may use to select Auto Scale or a Fixed Scale you customize by setting the minimum and maximum for the axis as well as the unit of measurement. Any configuration changes made in full page view are persistent and will remain when you return to the main Wireless Performance page.
