Dashboard Monitoring
The ArubaOS dashboard monitoring functionality provides enhanced visibility into your wireless network
performance and usage within a controller. This allows you to easily locate and diagnose WLAN issues in the
controller.
The dashboard monitoring is available via the WebUI. To monitor and troubleshoot RF issues in the WLAN, click
the Dashboard tab. The following pages in the Dashboard page allows you to view various performance and
usage information:
l Performance
l Usage
l Security
l AppRF
l Potential Issues
l WLANs
l Access Points
l Clients
l Firewall
l AirGroup
l UCC
Additionally, you can view the context sensitive help for each field in the Dashboard UI by clicking the help
link at the topmost right corner of the UI. The field for which the help has been defined appears as green. You
can turn off the help by clicking Done.
You can use the Search functionality to find the matched results for clients, APs, and WLANs. Click the count on the
search results of clients, APs, and WLANs to navigate the related summary page with the filters applied.
Performance
This page displays the performance details of the wireless clients and APs connected to the controller.
Clients
This section displays the total number of wireless clients connected to the controller. You can view the
distribution of clients in different client health ranges, SNR ranges, associated data rate ranges, and data
transfer speed ranges using the histograms and distributed charts. You can click on the hyperlinked number to
view the data in different screens with histograms.
An AP’s client health is the efficiency at which that AP transmits downstream traffic to a particular client. This
value is determined by comparing the amount of time the AP spends transmitting data to a client to the
amount of time that would be required under ideal conditions, that is, at the maximum Rx rate supported by
client, with no data retries.
A client health metric of 100% means the actual airtime the AP spends transmitting data is equal to the ideal
amount of time required to send data to the client. A client health metric of 50% means the AP is taking twice
as long as is ideal, or is sending one extra transmission to that client for every packet. A metric of 25% means
