bobby老师，我 grpc配置好了健康检查（grpc_health包），但是在consul健康检查中没有任何输出，这个输出应该是grpc_health定义好的吧，请问下这个怎么解决？

from concurrent import futures
import logging

import grpc
from helloworld import helloworld_pb2
from helloworld import helloworld_pb2_grpc
from helloworld.common.grpc_health.v1 import health_pb2, health_pb2_grpc
from helloworld.common.grpc_health.v1 import health


class Greeter(helloworld_pb2_grpc.GreeterServicer):

    def SayHello(self, request, context):
        return helloworld_pb2.HelloReply(message='Hello, %s!' % request.name)


def serve():
    server = grpc.server(futures.ThreadPoolExecutor(max_workers=10))
    helloworld_pb2_grpc.add_GreeterServicer_to_server(Greeter(), server)
    # 注册健康检查
    health_pb2_grpc.add_HealthServicer_to_server(health.HealthServicer(), server)
    server.add_insecure_port('192.168.11.1:50051')
    server.start()
    server.wait_for_termination()


if __name__ == '__main__':
    logging.basicConfig()
    serve()
