有谁知道如何将Spring Boot指标与datadog集成在一起?
Datadog是针对IT的云规模监视服务。
它使用户可以使用大量图表轻松地查看其数据。
我有一个Spring Boot应用程序,它使用dropwizard指标来填充有关我用@Timed
注释的所有方法的大量信息。
另一方面,我将应用程序部署在heroku中,因此无法安装Datadog代理。
我想知道是否有一种方法可以自动将spring boot metric系统报告与datadog集成。
最佳答案
我终于找到了一个dropwizzard模块,该模块将该库与datadog集成在一起:metrics-datadog
我创建了一个Spring配置类,该类使用YAML的属性创建并初始化此Reporter。
只需在您的pom中插入此依赖项即可:
<!-- 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您的项目中:
/**
* 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());
