1. springboot项目加入actuator和prometheus依赖

      1. <dependency>
      2.  <groupId>org.springframework.boot</groupId>
      3. <artifactId>spring-boot-starter-actuator</artifactId>
      4. </dependency>
      5. <dependency>
      6. <groupId>io.micrometer</groupId>
      7. <artifactId>micrometer-registry-prometheus</artifactId>
      8. </dependency>

    2. springboot暴露服务端口

      management:
endpoints:
 web:
   exposure:
     include: health,info,env,metrics,prometheus,beans
server:
 port: 9001

      暴露端口建议在内网环境下，不然会有敏感数据泄露的问题

    3. prometheus配置文件修改，增加新的job

      - job_name: admin
 metrics_path: '/actuator/prometheus'
 static_configs:
   - targets: ['172.20.100.52:9001']//端口为actuator暴露的端口
     labels:
       instance: admin

    4. grafana增加对springboot项目的panel，配置想要暴露的监控materics
