+# 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
+ <dependency>
+ <groupId>org.apache.dubbo</groupId>
+ <artifactId>dubbo-spring-boot-observability-starter</artifactId>
+</dependency>
+
+```
+* 服务端
+```xml
+<dubbo:metrics protocol="prometheus">
+ <dubbo:aggregation enabled="true"/>
+</dubbo:metrics>
+
+```
+
+* 客户端
+```xml
+ <dubbo:metrics protocol="prometheus">
+ <dubbo:aggregation enabled="true"/>
+</dubbo:metrics>
+
+```
+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：
