    CloudMonitor：即時匯出監控資料

    更新時間：Jun 19, 2024

    當您需要匯出雲上監控資料時，可以使用CloudMonitor提供的即時資料匯出功能。

    前提條件

    請確保您已開通企業CloudMonitor。具體操作，請參見開通企業CloudMonitor。

    背景資訊

    開通企業CloudMonitor不會產生任何費用，後續將按照實際使用量進行計費。關於即時資料匯出的計費標準，請參見即時資料匯出。

    操作步驟

    1. 調用DescribeMetricMetaList介面擷取各雲產品的監控指標列表。

      關於DescribeMetricMetaList介面中各參數的設定方法，請參見DescribeMetricMetaList。

      說明

      您可以從雲產品監控項中擷取各雲產品監控指標的Namespace、MetricName、Dimensions、Period和Statistics。

      1. 通過Maven引入CloudMonitor的SDK。

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

      2. 調用DescribeMetricMetaList介面擷取各雲產品的監控指標列表。

        SDK請求樣本如下：

        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. 擷取監控指標。

      1. 通過Pom引入CloudMonitor擷取監控資料的SDK。

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

      2. 調用Cursor介面定義匯出監控資料的範圍，並返回用於初始調用BatchExport介面的Cursor值。

        關於Cursor介面中各參數的設定方法，請參見Cursor。

        Cursor和BatchExpor支援所有地區，請參見服務存取點。

        SDK請求樣本如下：

        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返回結果如下：

      3. 調用BatchExport介面匯出在Cursor介面中定義的監控資料。

        關於BatchExport介面中各參數的設定方法，請參見BatchExport。

        SDK請求樣本如下：

        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返回結果如下：

    即時匯出監控資料樣本

    • 樣本1：連續匯出CloudMonitor中網站監控acs_networkmonitor的監控指標Availability的監控資料。

      1. 擷取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. 匯出監控資料。

        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. 連續匯出監控指標Availability的監控資料。

        例如：設定定時器為3秒，即每3秒匯出一次監控資料。

        public class Demo1 {
    private String cursor;
    @Scheduled(cron = "*/3 * * * * ?")
    public void getCpuData() throws Exception {
        System.out.println("開始擷取資料。");
        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("結束擷取資料。");
    }
}

  	config.setEndpoint("metrics.cn-hangzhou.aliyuncs.com");
  	return config;
	}
	private static String getCursor() throws Exception {
		Client client = new Client(getConfig(config));
