extends io.grpc.health.v1.HealthGrpc.HealthImplBase

An implementation of HealthImplBase that determines the healthiness of a Server and the healthiness of each gRPC service.

If an empty service name is specified, the server health is returned. Note: The suggested format of service name is package_names.ServiceName If a server is healthy, returns ServingStatus.SERVING is returned. For more details, please refer to the following URL.
