Standardize wireless health metrics 6.4.2

Health metrics calculations are standardized in the backend. Consistent colors are used to represent health status and differentiate between band frequency. The health data is now available through a REST API so that this information is standardized across other platforms.

The following colors are used for health status:

• Good = green
• Fair = yellow
• Poor = red

The following colors are used for band frequency:

• 2.4 GHz = light blue
• 5.0 GHz = dark blue

Sample diagnostics

• WiFi & Switch Controller > Managed FortiAPs > Diagnostics and Tools for a select FortiAP:

  

• WiFi & Switch Controller > WiFi Clients:

  

• WiFi & Switch Controller > WiFi Clients > Diagnostics and Tools for a select WiFi client:

  

REST API example:

https://<FortiGate IP>/api/v2/monitor/wifi/client
