本教程详细介绍如何使用Alibaba Cloud SDK for Java查询站点监控任务的细粒度和平均统计监控数据。

前提条件

在使用本教程前，请确保已完成以下操作：
  • 使用Alibaba Cloud SDK for Java，您需要一个阿里云账号和访问密钥（AccessKey）。 请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
  • 确保您已经安装了Alibaba Cloud SDK for Java，准确的SDK版本号，请参见 阿里云开发工具包（SDK）。

代码示例

本文操作示例主要以代码形式体现，具体代码如下： 
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.cms.model.v20190101.DescribeSiteMonitorDataRequest;
import com.aliyuncs.cms.model.v20190101.DescribeSiteMonitorDataResponse;
import com.aliyuncs.cms.model.v20190101.DescribeSiteMonitorStatisticsRequest;
import com.aliyuncs.cms.model.v20190101.DescribeSiteMonitorStatisticsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;

public class DescribeSiteMonitorDataDemo {

    /**
     * 查询任务的细粒度监控数据
     */
    private DescribeSiteMonitorDataResponse describeSiteMonitorData(DescribeSiteMonitorDataRequest request, IAcsClient client) throws ClientException {
        return client.getAcsResponse(request);
    }

    /**
     * 查询指定任务一段时间内的平均统计数据
     */
    private DescribeSiteMonitorStatisticsResponse describeSiteMonitorStatistics(DescribeSiteMonitorStatisticsRequest request, IAcsClient client) throws ClientException {
        return client.getAcsResponse(request);
    }

    private static void log_print(String functionName, Object result) {
        Gson gson = new Gson();
        System.out.println("-------------------------------" + functionName + "-------------------------------");
        System.out.println(gson.toJson(result));
    }

    public static void main(String[] args) {
        // 设置鉴权参数，初始化客户端
        DefaultProfile profile = DefaultProfile.getProfile(
                "cn-qingdao",// 地域ID
                "your-access-key-id",// 您的AccessKey ID
                "your-access-key-secret");// 您的AccessKey Secret
        IAcsClient client = new DefaultAcsClient(profile);

        DescribeSiteMonitorDataDemo describeSiteMonitorDataDemo = new DescribeSiteMonitorDataDemo();

        try {
            // 查询任务的细粒度监控数据
            DescribeSiteMonitorDataRequest describeSiteMonitorDataRequest = new DescribeSiteMonitorDataRequest();
            // 监控项的名称，可选为：Availability（可用率）、ResponseTime（响应时间)
            describeSiteMonitorDataRequest.setMetricName("Availability");
            // 任务ID
            describeSiteMonitorDataRequest.setTaskId("test");
            // 开始时间，可以传入时间戳，也可以传入format时间格式数据，如2019-10-10 00:00:00
            describeSiteMonitorDataRequest.setStartTime("2019-10-01 00:00:00");
            // 结束时间
            describeSiteMonitorDataRequest.setEndTime("2019-10-20 00:00:00");
            DescribeSiteMonitorDataResponse describeSiteMonitorDataResponse = describeSiteMonitorDataDemo.describeSiteMonitorData(describeSiteMonitorDataRequest, client);
            log_print("describeSiteMonitorData",describeSiteMonitorDataResponse);

            // 查询指定任务一段时间内的平均统计数据
            DescribeSiteMonitorStatisticsRequest describeSiteMonitorStatisticsRequest = new DescribeSiteMonitorStatisticsRequest();
            // 监控项的名称，可选为：Availability（可用率）、ResponseTime（响应时间)
            describeSiteMonitorStatisticsRequest.setMetricName("Availability");
            // 任务ID
            describeSiteMonitorStatisticsRequest.setTaskId("test");
            // 统计的时间周期， 单位是分钟，最大1440分钟（1天）
            describeSiteMonitorStatisticsRequest.setTimeRange("5");
            DescribeSiteMonitorStatisticsResponse describeSiteMonitorStatisticsResponse = describeSiteMonitorDataDemo.describeSiteMonitorStatistics(describeSiteMonitorStatisticsRequest, client);
            log_print("describeSiteMonitorStatistics",describeSiteMonitorStatisticsResponse);
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}

运行结果

正确的运行结果类似如下：
