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

                </configuration>
            </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

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
