实时导出监控数据

更新时间:

当您需要导出云上监控数据时,可以使用云监控提供的实时数据导出功能。

前提条件

请确保您已开通企业云监控。具体操作,请参见开通企业云监控

背景信息

开通企业云监控不会产生任何费用,后续将按照实际使用量进行计费。关于实时数据导出的计费标准,请参见实时数据导出

操作步骤

  1. 调用DescribeMetricMetaList接口获取各云产品的监控指标列表。

    关于DescribeMetricMetaList接口中各参数的设置方法,请参见DescribeMetricMetaList

    说明

    您可以从云产品监控项中获取各云产品监控指标的NamespaceMetricNameDimensionsPeriodStatistics

    1. 通过Maven引入云监控的SDK。

      <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>cms20190101</artifactId>
        <version><SDK包的最新版本></version>
      </dependency>

      请您获取云监控SDK包的最新版本,具体操作如下:

      1. 单击DescribeMetricMetaList接口。

      2. OpenAPI页面的SDK示例页签,将鼠标移至SDK信息

        SDK信息对话框,您可以查看SDK包名称和SDK最新版本。SDK_2019

    2. 调用DescribeMetricMetaList接口获取各云产品的监控指标列表。

      SDK请求示例如下:

      private static Client getClient() throws Exception {
          Config config = new Config()
          config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        	config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
          config.endpoint = "metrics.cn-hangzhou.aliyuncs.com";
          return new Client(config);
      }
      public static void main(String[] args) throws Exception {
          Client client = getClient();
          DescribeMetricMetaListRequest describeMetricMetaListRequest = new DescribeMetricMetaListRequest();
          describeMetricMetaListRequest.setNamespace("acs_ecs_dashboard");
          DescribeMetricMetaListResponse describeMetricMetaListResponse = client.describeMetricMetaList(describeMetricMetaListRequest);
          String json = JSON.toJSONString(describeMetricMetaListResponse.getBody());
          System.out.println(json);
      }
  2. 获取监控指标。

    1. 通过Pom引入云监控获取监控数据的SDK。

      <dependency>
          <groupId>com.aliyun</groupId>
          <artifactId>cms20190101</artifactId>
          <version><SDK包的最新版本></version>
      </dependency>

      请您获取云监控SDK包的最新版本,具体操作如下:

      1. 单击Cursor接口。

      2. OpenAPI页面的SDK示例页签,将鼠标移至SDK信息

        SDK信息对话框,您可以查看SDK包名称和SDK最新版本。SDK包

    2. 调用Cursor接口定义导出监控数据的范围,并返回用于初始调用BatchExport接口的Cursor值。

      关于Cursor接口中各参数的设置方法,请参见Cursor

      Cursor和BatchExpor支持所有地域,请参见服务接入点

      SDK请求示例如下:

      private static Config config = null;
      private static Config getConfig(Config config){
        config = new Config();
        config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
        config.setEndpoint("metrics.cn-hangzhou.aliyuncs.com");
        return config;
      }
      private static String getCursor() throws Exception {
          Client client = new Client(getConfig(config));
          CursorRequest cursorRequest = new CursorRequest();
          cursorRequest.setNamespace("acs_ecs_dashboard");
          cursorRequest.setMetric("CPUUtilization");
          cursorRequest.setPeriod(60);
          cursorRequest.setStartTime(System.currentTimeMillis() - 60 * 60 * 1000);
          cursorRequest.setEndTime(Long.MAX_VALUE);
        	List<Matcher> matchers = new ArrayList<>();
        	Matcher matcher = new Matcher();
        	matcher.setLabel("userId");
          matcher.setValue("173651113438****");
        	matcher.setOperator("EQUALS");
        	matchers.add(matcher);
          cursorRequest.setMatchers(matchers);
          CursorResponse cursorResponse = client.cursor(cursorRequest);
          if (cursorResponse == null || cursorResponse.getBody() == null || cursorResponse.getBody().getCursor() == null) {
            return null;
          }
          return cursorResponse.getBody().getCursor();
      }

      SDK返回结果如下:

    3. 调用BatchExport接口导出在Cursor接口中定义的监控数据。

      关于BatchExport接口中各参数的设置方法,请参见BatchExport

      SDK请求示例如下:

      private static String BatchExport(String cursor) throws Exception {
          Client client = new Client(getConfig(config));
          BatchExportRequest request = new BatchExportRequest();
          request.setNamespace("acs_ecs_dashboard");
          request.setMetric("CPUUtilization");
          request.setCursor(cursor);
          request.setLength(1000);
          BatchExportResponse response = client.batchExport(request);
          if (response == null || response.getBody() == null) {
            return null;
          }else {
            String json = JSON.toJSONString(response.getBody());
            return json;
          }
      }

      SDK返回结果如下:

实时导出监控数据示例

  • 示例1:连续导出云监控中站点监控acs_networkmonitor的监控指标Availability的监控数据。

    1. 获取Cursor。

      public class GetDataUtil {
          private static Config config = null;
      		private static Config getConfig(Config config){
        	config = new Config();
        	config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        	config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
        	config.setEndpoint("metrics.cn-hangzhou.aliyuncs.com");
        	return config;
      	}
      	private static String getCursor() throws Exception {
      		Client client = new Client(getConfig(config));
       	  CursorRequest cursorRequest = new CursorRequest();
       	  cursorRequest.setNamespace("acs_ecs_dashboard");
          cursorRequest.setMetric("CPUUtilization");
          cursorRequest.setPeriod(60);
          cursorRequest.setStartTime(System.currentTimeMillis() - 60 * 60 * 1000);
          cursorRequest.setEndTime(Long.MAX_VALUE);
        	List<Matcher> matchers = new ArrayList<>();
        	Matcher matcher = new Matcher();
        	matcher.setLabel("userId");
          matcher.setValue("173651113438****");
        	matcher.setOperator("EQUALS");
        	matchers.add(matcher);
          cursorRequest.setMatchers(matchers);
          CursorResponse cursorResponse = client.cursor(cursorRequest);
          if (cursorResponse == null || cursorResponse.getBody() == null || cursorResponse.getBody().getCursor() == null) {
            return null;
          }
          return cursorResponse.getBody().getCursor();
      	}
      
          // ...
      }
    2. 导出监控数据。

      public class GetDataUtil {
          // ...
      
          private static String BatchExport(String cursor) throws Exception {
          	Client client = new Client(getConfig(config));
          	BatchExportRequest request = new BatchExportRequest();
          	request.setNamespace("acs_ecs_dashboard");
          	request.setMetric("CPUUtilization");
          	request.setCursor(cursor);
          	request.setLength(1000);
          	BatchExportResponse response = client.batchExport(request);
          	if (response == null || response.getBody() == null) {
            	return null;
          	}else {
            	String json = JSON.toJSONString(response.getBody());
            	return json;
          	}
      	}
      }
    3. 连续导出监控指标Availability的监控数据。

      例如:设置定时器为3秒,即每3秒导出一次监控数据。

      public class Demo1 {
          private String cursor;
          @Scheduled(cron = "*/3 * * * * ?")
          public void getCpuData() throws Exception {
              System.out.println("开始获取数据。");
              if(cursor == null){
                  Matcher matcher = new Matcher();
                  matcher.setLabel("userId").setOperator("EQUALS").setValue("173651113438****");
                  List<Matcher> chain  = new ArrayList<>();
                  chain.add(matcher);
                  cursor = GetDataUtil.getCursor("acs_networkmonitor","Availability",60,System.currentTimeMillis() - 60 * 60 * 1000,Long.MAX_VALUE,chain);
              }
              String sth = GetDataUtil.BatchExport(cursor,"acs_networkmonitor","Availability",10);
              JSONObject jsonObject = JSONObject.parseObject(sth);
              if(!StringUtils.isEmpty(jsonObject.getString("cursor"))){
                  cursor = jsonObject.getString("cursor");
              }
              System.out.println("结束获取数据。");
          }
      }
  • 示例2:连续导出云监控中站点监控acs_networkmonitor的监控指标AvailabilityAvailability_new的监控数据。

    1. 获取Cursor。

      public class GetDataUtil {
          private static Config config = null;

        	config = new Config();
        	config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
        	config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
        	config.setEndpoint("metrics.cn-hangzhou.aliyuncs.com");
        	return config;
      	}
      	private static String getCursor() throws Exception {
      		Client client = new Client(getConfig(config));
       	  CursorRequest cursorRequest = new CursorRequest();
       	  cursorRequest.setNamespace("acs_ecs_dashboard");
          cursorRequest.setMetric("CPUUtilization");
          cursorRequest.setPeriod(60);
          cursorRequest.setStartTime(System.currentTimeMillis() - 60 * 60 * 1000);
          cursorRequest.setEndTime(Long.MAX_VALUE);
        	List<Matcher> matchers = new ArrayList<>();
        	Matcher matcher = new Matcher();
        	matcher.setLabel("userId");
          matcher.setValue("173651113438****");
        	matcher.setOperator("EQUALS");
        	matchers.add(matcher);
          cursorRequest.setMatchers(matchers);
          CursorResponse cursorResponse = client.cursor(cursorRequest);
          if (cursorResponse == null || cursorResponse.getBody() == null || cursorResponse.getBody().getCursor() == null) {
            return null;
          }
          return cursorResponse.getBody().getCursor();
      	}
      
          // ...
      }
    2. 导出监控数据。

      public class GetDataUtil {
          // ...
      
          private static String BatchExport(String cursor) throws Exception {
          	Client client = new Client(getConfig(config));
          	BatchExportRequest request = new BatchExportRequest();
          	request.setNamespace("acs_ecs_dashboard");
          	request.setMetric("CPUUtilization");
          	request.setCursor(cursor);
          	request.setLength(1000);
          	BatchExportResponse response = client.batchExport(request);
          	if (response == null || response.getBody() == null) {
            	return null;
          	}else {
            	String json = JSON.toJSONString(response.getBody());
            	return json;
          	}
      	}
      }

    3. 连续导出监控指标AvailabilityAvailability_new的监控数据。

      例如:设置定时器为3秒,即每3秒导出一次监控数据。

      public class Demo2 {
          private String availabilityCursor;
          private String availability_newCursor;
          @Scheduled(cron = "*/3 * * * * ?")
          public void getCpuData() throws Exception {
              System.out.println("开始获取数据。");
              if(availabilityCursor == null){
