SD-WAN Web Access Layer
The HTTP test mapped to this layer emulates an HTTP access to the web interface of the SD-WAN appliance, and reports the availability and responsiveness of the web console to HTTP requests. In addition to the HTTP test, the layer also monitors the validity of the SSL certificates (if any).
