### 50.5 记录自己的指标 将[CounterService](https://github.com/spring-projects/spring-boot/blob/master/spring-boot-actuator/src/main/java/org/springframework/boot/actuate/metrics/CounterService.java)或[GaugeService](http://github.com/spring-projects/spring-boot/tree/master/spring-boot-actuator/src/main/java/org/springframework/boot/actuate/metrics/GaugeService.java)注入到你的bean中可以记录自己的度量指标：`CounterService`暴露`increment`，`decrement`和`reset`方法；`GaugeService`提供一个`submit`方法。 下面是一个简单的示例，它记录了方法调用的次数： ```java import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.actuate.metrics.CounterService; import org.springframework.stereotype.Service; @Service public class MyService { private final CounterService counterService; @Autowired public MyService(CounterService counterService) { this.counterService = counterService; } public void exampleMethod() { this.counterService.increment("services.system.myservice.invoked"); } } ``` **注** 你可以将任何字符串用作度量指标的名称，但最好遵循所选存储/图形技术的指南，[Matt Aimonetti’s Blog](http://matt.aimonetti.net/posts/2013/06/26/practical-guide-to-graphite-monitoring/)中有一些好的关于Graphite的指南。
