Explanation
The goal is to route all traffic away from a backend server when port 8080 becomes unavailable on that server. The correct solution is to create a custom health probe targeting port 8080. By default, Azure Application Gateway health probes check the port defined in the HTTP settings (typically 80 or 443). A custom health probe can be configured to specifically check port 8080 on each backend server. If port 8080 is unresponsive, the health probe marks that backend server as unhealthy, and the Application Gateway automatically stops sending traffic to it, routing all requests to the remaining healthy backend server. Adding rules, listeners, or changing the listener port would not address the health monitoring of port 8080 on the backend.
