-For a UDP service, target availability can be tested using non-UDP health checks on your target group. You can use any available health check (TCP, HTTP, or HTTPS), and any port on your target to verify the availability of a UDP service. If the service receiving the health check fails, your target is considered unavailable. To improve the accuracy of health checks for a UDP service, configure the service listening to the health check port to track the status of your UDP service and fail the health check if the service is unavailable.
