SpringBoot►Prometheus , 评论

步骤一：引入Spring Boot Actuator依赖，进行初始配置

<!-- spring-boot-actuator依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!-- prometheus依赖 -->
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

步骤二：在bootstrap-环境标示.yml中添加相关配置暴露监测数据端口。例如，端口为19098。

提示：监控端口根据自身服务设置，例如：微服务端口是：9098，监控端口设置为：19098，方便识别管理

#prometheus监控平台配置
management:
  server:
    port: 19098  # 直接访问这个端口即可显示相关监控接口
  endpoints:
    jmx:
      exposure:
        include: "*"
    web:
      exposure:
        include: "*"
        exclude: configprops
  endpoint:
    health:
      show-details: ALWAYS
  metrics:
    tags:
      application: ${spring.application.name}

步骤三：启动服务，访问 http://localhost:19098/metrics

接口返回：
