Prosedur

Panggil operasi DescribeMetricMetaList untuk mengambil daftar metrik setiap layanan Alibaba Cloud.

Untuk detail parameter, lihat DescribeMetricMetaList.

Catatan

Nilai Namespace, MetricName, Dimensions, Period, dan Statistics untuk setiap layanan tercantum dalam Metrik layanan Alibaba Cloud.

Tambahkan dependensi SDK Cloud Monitor menggunakan Maven.

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>cms20190101</artifactId>
  <version><LATEST_SDK_VERSION></version>
</dependency>

Panggil operasi DescribeMetricMetaList untuk mengambil daftar metrik setiap layanan Alibaba Cloud.

Contoh permintaan SDK:

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);
}

Ambil metrik.

Tambahkan dependensi SDK ke file pom.xml Anda.

Panggil operasi Cursor untuk menentukan cakupan ekspor data. Operasi ini mengembalikan cursor yang diperlukan untuk panggilan BatchExport awal.

Untuk detail parameter, lihat Cursor.

Operasi Cursor dan BatchExport tersedia di semua wilayah. Endpoints.

Contoh permintaan SDK:

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();
}

Panggil operasi BatchExport untuk mengekspor data pemantauan yang ditentukan oleh operasi Cursor.

Untuk detail parameter, lihat BatchExport.

Contoh permintaan SDK:

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;

Contoh

Contoh 1: Ekspor data pemantauan secara berkelanjutan untuk metrik Availability dalam namespace acs_networkmonitor pada pemantauan situs.

Ambil 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(String namespace, String metric, int period, long startTime, long endTime, List<Matcher> matchers) throws Exception {
		Client client = new Client(getConfig(config));
 	  CursorRequest cursorRequest = new CursorRequest();
 	  cursorRequest.setNamespace(namespace);
    cursorRequest.setMetric(metric);
    cursorRequest.setPeriod(period);
    cursorRequest.setStartTime(startTime);
    cursorRequest.setEndTime(endTime);
    cursorRequest.setMatchers(matchers);
    CursorResponse cursorResponse = client.cursor(cursorRequest);
    if (cursorResponse == null || cursorResponse.getBody() == null || cursorResponse.getBody().getCursor() == null) {
      return null;
    }
    return cursorResponse.getBody().getCursor();
	}

    // ...
}

Ekspor data pemantauan.

public class GetDataUtil {
    // ...

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

Ekspor data pemantauan secara berkelanjutan untuk metrik Availability.

Contoh berikut menggunakan pengatur waktu 3 detik:

public class Demo1 {
    private String cursor;
    @Scheduled(cron = "*/3 * * * * ?")
    public void getCpuData() throws Exception {
        System.out.println("Start retrieving data.");
        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("Finished retrieving data.");
    }
}

Contoh 2: Ekspor data pemantauan secara berkelanjutan untuk metrik Availability dan Availability_new dalam namespace acs_networkmonitor pada pemantauan situs.

Ambil 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"));

  	return config;
	}
	private static String getCursor(String namespace, String metric, int period, long startTime, long endTime, List<Matcher> matchers) throws Exception {
		Client client = new Client(getConfig(config));
 	  CursorRequest cursorRequest = new CursorRequest();
 	  cursorRequest.setNamespace(namespace);
    cursorRequest.setMetric(metric);
    cursorRequest.setPeriod(period);
    cursorRequest.setStartTime(startTime);
