部署在内网的阿里云怎么查看ECS的服务接入地址

我想通过ecs插件获取主机资源信息，比如cpu/硬盘使用率等等，可现在阿里云部署在内网，域名应该怎么获取？

 Config config = new Config();
        config.accessKeyId = accessKeyId;
        config.accessKeySecret = secret;
        // 访问的域名
        config.endpoint = "metrics.aliyuncs.com";
        com.aliyun.cms20190101.Client client =  new com.aliyun.cms20190101.Client(config);
        DescribeMetricLastRequest describeMetricLastRequest = new DescribeMetricLastRequest();
        describeMetricLastRequest.setMetricName(metricName);
        describeMetricLastRequest.setNamespace("acs_ecs_dashboard");
        describeMetricLastRequest.setDimensions("[{\"instanceId\":\""+instanceId+"\"}]");
        DescribeMetricLastResponse response = client.describeMetricLast(describeMetricLastRequest);```
