  • Spring Boot Admin 监控中心

    Spring Boot Admin 监控中心

    Spring Boot Admin用来收集微服务系统的健康状态、会话数量、并发数、服务资源、延迟等度量信息

    服务端

    建立spring-cloud-admin maven工程,导入pom依赖和完善目录结构

    pom依赖

    pom.xml 注意增加了两个依赖:

    org.jolokia:jolokia-core、de.codecentric:spring-boot-admin-starter-server

    注意maven依赖的版本:在新建maven项目完善结构时,下载,启动报错很大可能就是maven版本依赖不对,因为版本在不断更新,有些版本和插件会被更新或废弃,这时需要自己去仓库确认

                </plugin>
            </plugins>
        </build>
    </project>
    

    启动类中增加@EnableAdminServer注解

    package com.outlook.liufei32.spring.cloud.admin;
    
    import de.codecentric.boot.admin.server.config.EnableAdminServer;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    @SpringBootApplication
    @EnableAdminServer
    @EnableEurekaClient
    public class AdminApplication {
        public static void main( String[] args ) {
            SpringApplication.run(AdminApplication.class, args);
        }
    }
    

    配置application.yml

    spring:
      application:
        name: spring-cloud-admin
      zipkin:
        base-url: http://localhost:9411
    
    server:
      port: 8084
    
    management:
      endpoint:
        health:
          show-details: always
      endpoints:
        web:
          exposure:
            include: health,info
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8761/eureka/
    

    启动访问

    输入yml配置的url :http://localhost:8084
    b46aa5718b82a7779f3c8d771e254e2e.png

    客户端

    客户端的配置就是将需要监控的微服务注册到admin的服务端

    1.增加pom依赖

    <!--admin监控客户端 start-->
            <dependency>
                <groupId>org.jolokia</groupId>
                <artifactId>jolokia-core</artifactId>
            </dependency>
            <dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-starter-client</artifactId>
            </dependency>
            <!--admin监控客户端 end-->
    

    2.配置yml

    spring:
      boot:
        admin:
          client:
            url: http://localhost:8084
    

    启动完成就能监控服务情况
