Spring Actuator常用接口

• http://localhost:9080/actuator
  导入依赖

		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

配置文件添加如下配置

management.endpoints.web.exposure.include=*

启动服务后调用上方接口可以看到暴露出来的监控信息

/health

• http://localhost:8080/actuator/health
  用于监控各种服务健康，还可以监控tomcat,mq，redis等

"status":"UP","details":{"nacosConfig":{"status":"UP"},"diskSpace":{"status":"UP","details":{"total":125872107520,"free":88245694464,"threshold":10485760}},"db":{"status":"UP","details":{"database":"MySQL","hello":1}},"mail":{"status":"UP","details":{"location":"smtp.qq.com:-1"}},"refreshScope":{"status":"UP"},"discoveryComposite":{"status":"UP","details":{"discoveryClient":{"status":"UP","details":{"services":["platform-admin"]}}}},"hystrix":{"status":"UP"},"redis":{"status":"UP","details":{"version":"3.0.504"}}}}

注：配置文件需开启展示详细信息

#显示健康状态详细信息
management.endpoint.health.show-details=always
