简介

用于对 Spring Boot 应用的管理和监控。可以用来监控服务是否健康、是否在线、以及一些jvm数据等等

Spring Boot Admin 分为服务端(spring-boot-admin-server)和客户端(spring-boot-admin-client)，服务端和客户端之间采用 http 通讯方式实现数据交互；单体项目中需要整合 spring-boot-admin-client 才能让应用被监控

在 SpringCloud 项目中，spring-boot-admin-server 是直接从注册中心抓取应用信息，不需要每个微服务应用整合 spring-boot-admin-client 就可以实现应用的管理和监控

单体项目

服务端

引入spring-boot-admin服务端依赖

启动类上开启admin@EnableAdminServer

java">@SpringBootApplication
@EnableAdminServer
public class MonitorApplication {public static void main(String[] args) {SpringApplication.run(MonitorApplication.class, args);}
}

客户端

客户端不用引spring-boot-admin-starter-clien依赖，springbootadmin会去服务列表里找

如果客户端服务有配置context-path路径，则需添加yml配置

spring:cloud:nacos:discovery:metadata:  # minitor监控的context-path配置management:context-path: ${server.servlet.context-path}/actuator

注意：如果安装的springbootadmin服务的和客户端不在一个局域网，需要设置客户端注册到nacos的IP地址，springbootadmin才能通过实际ip地址找到客户端

spring:cloud:nacos:config:server-addr: @config.server-addr@group: @config.group@namespace: @config.namespace@username: @config.username@password: @config.password@discovery:metadata:  # minitor监控的context-path配置management:context-path: ${server.servlet.context-path}/actuatorserver-addr: ${spring.cloud.nacos.config.server-addr}group: @config.group@namespace: @config.namespace@username: @config.username@password: @config.password@ip: 192.168.11.50

如果需要查看日记，就需要每一个客户端都需要设置读取各自日记的文件名字

# 服务端点详细监控信息
management:endpoint:logfile: # 日志（想在线看日志才配）external-file: ./logs/client-info.log # 日志所在路径
