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)
    <dependencies>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-core --&gt;     <dependency&gt;         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-core</artifactId>         <version>4.4.3</version>     </dependency>     <!-- https://mvnrepository.com/artifact/com.aliyun/aliyun-java-sdk-cms -->     <dependency>         <groupId>com.aliyun</groupId>         <artifactId>aliyun-java-sdk-cms</artifactId>         <version>7.0.4</version>     </dependency> </dependencies>

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:

-------------------------------describeSiteMonitorData------------------------------- {   "Data": [     {       "Over5totalTime": 0,       "Error4XXRate": 0,       "UnavailableNumber": 0,       "Over2totalTime": 0,       "Over100FailureRate": 0,       "timestamp": 1551581040000,       "Over10FailureRate": 0,       "Availability": 100,       "userId": "12345",       "Over80FailureRate": 0,       "AvailableNumber": 2,       "Unavailability": 0,       "ErrorCodeMaximum": 0,       "Over10totalTime": 0,       "taskId": "49f7b317-7645-4cc9-94fd-1****",       "Over30FailureRate": 0,       "Error6XXRate": 0,       "Over500NumberRate": 0,       "Over3totalTime": 0,       "Over400NumberRate": 0,       "Error5XXRate": 0,       "Error5XXNumber": 0,       "Over90FailureRate": 0,       "Error4XXNumber": 0,       "Over50FailureRate": 0,       "ErrorCodeMinimum": 0,       "Error6XXNumber": 0     },     {       "Over5totalTime": 0,       "Error4XXRate": 0,       "UnavailableNumber": 0,       "Over2totalTime": 0,       "Over100FailureRate": 0,       "timestamp": 1551581100000,       "Over10FailureRate": 0,       "Availability": 100,       "userId": "12345",       "Over80FailureRate": 0,       "AvailableNumber": 2,       "Unavailability": 0,       "ErrorCodeMaximum": 0,       "Over10totalTime": 0,       "taskId": "49f7b317-7645-4cc9-94fd-1****",       "Over30FailureRate": 0,       "Error6XXRate": 0,       "Over500NumberRate": 0,       "Over3totalTime": 0,       "Over400NumberRate": 0,       "Error5XXRate": 0,       "Error5XXNumber": 0,       "Over90FailureRate": 0,       "Error4XXNumber": 0,       "Over50FailureRate": 0,       "ErrorCodeMinimum": 0,       "Error6XXNumber": 0     }   ],   "RequestId": "DBDEAC51-EA3C-4853-8F25-6B48D38A28A9",   "Success": true,   "Code": "200" } -------------------------------describeSiteMonitorStatistics------------------------------- {     "code": "200",     "message": "successful",     "success": "true",     "requestId": "157DB25A-2AB4-4907-9306-05DD1434B0BF",     "data": "" }
