+# 使用Metrics模块进行数据采集然后暴漏数据给普罗米修斯监控
+Dubbo使用开源的[Dubbo Metrics](https://github.com/alibaba/metrics)进行数据埋点,并且通过服务暴露,使用的时候,首先需要进行配置:
+
+* 依赖(其中Dubbo版本在3.2.0及以后)
+```xml
+
+ org.apache.dubbo
+ dubbo-spring-boot-observability-starter
+
+
+```
+* 服务端
+```xml
+
+
+
+
+```
+
+* 客户端
+```xml
+
+
+
+
+```
+先启动服务端,然后启动客户端,
+提供端监控指标:http://localhost:20888/metrics
+消费端监控指标:http://localhost:20889/metrics
+
+
+可观测性文档如下链接:
