### 44.4. 记录自己的指标
|
||
|
||
想要记录你自己的指标，只需将[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。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**：你可以将任何的字符串用作指标的名称，但最好遵循所选存储或图技术的指南。[Matt Aimonetti’s Blog](http://matt.aimonetti.net/posts/2013/06/26/practical-guide-to-graphite-monitoring/)中有一些好的关于图（Graphite）的指南。
