Modules
A Failover backend defines failover behavior within a list of referenced backends. Traffic is sent to the first backend in the list. If that backend is offline or no connection can be established, ngrok attempts to connect to the next backend in the list until one is successful.
A Tunnel Group Backend balances traffic among all online tunnels that match a label selector.
A Weighted Backend balances traffic among the referenced backends. Traffic is assigned proportionally to each based on its weight. The percentage of traffic is calculated by dividing a backend’s weight by the sum of all weights.
