+### 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。
