Spring boot指标+ datadog

Question

有人知道如何将Spring引导指标与datadog集成在一起吗？

Datadog是面向IT的云级监控服务。

它允许用户使用大量的图表和图形轻松可视化他们的数据。

我有一个spring boot应用程序，它使用dropwizard指标来填充关于我用@Timed注释的所有方法的大量信息。

另一方面，我在heroku中部署我的应用程序，所以我不能安装Datadog代理。

我想知道是否有一种方法可以自动集成spring boot指标系统报告和datadog。

我终于找到了一个dropwizzard模块，它集成了这个库和datadog：metrics-datadog

我已经创建了一个Spring configuration类，它使用YAML的属性创建和初始化这个Reporter。

只需在您的pom中插入以下依赖项：

    <!-- Send metrics to Datadog -->
    <dependency>
        <groupId>org.coursera</groupId>
        <artifactId>dropwizard-metrics-datadog</artifactId>
        <version>1.1.3</version>
    </dependency>

将此配置添加到您的YAML：

yourapp:
  metrics:
    apiKey: <your API key>
    host: <your host>
    period: 10
    enabled: true

并将此配置类添加到项目中：

/**
 * This bean will create and configure a DatadogReporter that will be in charge of sending
 * all the metrics collected by Spring Boot actuator system to Datadog.
 *     
 * @see https://www.datadoghq.com/
 * @author jfcorugedo
 *
 */
@Configuration
@ConfigurationProperties("yourapp.metrics")
public class DatadogReporterConfig {

  private static final Logger LOGGER = LoggerFactory.getLogger(DatadogReporterConfig.class);

  /** Datadog API key used to authenticate every request to Datadog API */
  private String apiKey;

  /** Logical name associated to all the events send by this application */
  private String host;

  /** Time, in seconds, between every call to Datadog API. The lower this value the more information will be send to Datadog */
  private long period;

  /** This flag enables or disables the datadog reporter */
  private boolean enabled = false;

  @Bean
  @Autowired
  public DatadogReporter datadogReporter(MetricRegistry registry) {

      DatadogReporter reporter = null;
      if(enabled) {
          reporter = enableDatadogMetrics(registry);
      } else {
          if(LOGGER.isWarnEnabled()) {
              LOGGER.info("Datadog reporter is disabled. To turn on this feature just set 'rJavaServer.metrics.enabled:true' in your config file (property or YAML)");
          }
      }

      return reporter;
  }

  private DatadogReporter enableDatadogMetrics(MetricRegistry registry) {

      if(LOGGER.isInfoEnabled()) {
          LOGGER.info("Initializing Datadog reporter using [ host: {}, period(seconds):{}, api-key:{} ]", getHost(), getPeriod(), getApiKey());
      }

      EnumSet<Expansion> expansions = DatadogReporter.Expansion.ALL;
      HttpTransport httpTransport = new HttpTransport
                                .Builder()
                                .withApiKey(getApiKey())
                                .build();

      DatadogReporter reporter = DatadogReporter.forRegistry(registry)
        .withHost(getHost())
        .withTransport(httpTransport)
        .withExpansions(expansions)
        .build();

      reporter.start(getPeriod(), TimeUnit.SECONDS);

      if(LOGGER.isInfoEnabled()) {
          LOGGER.info("Datadog reporter successfully initialized");
      }

      return reporter;
  }

  /**
   * @return Datadog API key used to authenticate every request to Datadog API
   */
  public String getApiKey() {
      return apiKey;
  }

  /**
   * @param apiKey Datadog API key used to authenticate every request to Datadog API
   */
  public void setApiKey(String apiKey) {
      this.apiKey = apiKey;
  }

  /**
   * @return Logical name associated to all the events send by this application
   */
  public String getHost() {
      return host;
  }

  /**
   * @param host Logical name associated to all the events send by this application
   */
  public void setHost(String host) {
      this.host = host;
  }

  /**
   * @return Time, in seconds, between every call to Datadog API. The lower this value the more information will be send to Datadog
   */
  public long getPeriod() {
      return period;
  }

  /**
   * @param period Time, in seconds, between every call to Datadog API. The lower this value the more information will be send to Datadog
   */
  public void setPeriod(long period) {
      this.period = period;
  }

  /**
   * @return true if DatadogReporter is enabled in this application
   */
  public boolean isEnabled() {
      return enabled;
  }

  /**
   * This flag enables or disables the datadog reporter.
   * This flag is only read during initialization, subsequent changes on this value will no take effect 
   * @param enabled
   */
  public void setEnabled(boolean enabled) {
      this.enabled = enabled;
  }
}

Answer 2

Spring Boot2.x似乎在其指标中添加了几个监控系统。micrometer.io支持的DataDog就是其中之一。请参阅参考文档：https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-metrics.html#production-ready-metrics-export-newrelic

对于Spring Boot 1.x，可以使用back-ported：

compile 'io.micrometer:micrometer-spring-legacy:latest.release'

如果您可以选择JMX，则可以结合使用java datalog integration和JMX dropwizrd reporter
