Additionally, you can view the distribution of the APs in different noise floor ranges, channel utilization ranges, and
non-Wi-Fi interference ranges using the histograms. To understand histogram information, see "Using Dashboard
Histograms" on page 616.
Using Dashboard Histograms
Dashboard histograms are a visual representation of the distribution of the wireless clients, access points, and radios
across different performance parameters in the controller. Histograms help you to quickly identify any performance
issues in the network from the color of the distribution. For example, critical ranges of the distribution are
highlighted in red and the normal ranges are highlighted in green.
You can view the number of clients or APs falling in each range of the distribution with a hyperlink. You can also
perform the following tasks on the histograms to get additional information on the clients and APs in the
distribution:
l View Client or AP details: Click the hyperlinked number to view the details of the clients or APs in a pop-up
window.
l Sort: Click a column header of the clients or APs table to sort the complete list based on the entries on the
active column. You can also use the sort icon that appears when you click on a column for sorting.
l Filter: Click the filter icon and select the filter criterion on any column to filter the entries.
l Customize column view: Select or deselect the columns to view or hide by doing a right click on the clients or
AP table header.
l Close pop-up window: Click on the close icon to close the client or AP details pop-up window.
