server.port=8005

package com.wyx;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import de.codecentric.boot.admin.server.config.EnableAdminServer;

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

再做另外一个项目，并且把这个项目注册到服务中

server.port=8017

spring.boot.admin.client.url=http://localhost:8005
spring.application.name=test3

management.endpoints.web.exposure.include=*
logging.file=D\:/myeclipseworkspaces/test3/spring-boot-admin-client.log

package com.tszr;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Test3 {
    public static void main(String[] args) {
        SpringApplication.run(Test3.class, args);
    }
}

 

 

spring.boot.admin.client.url：Spring Boot Admin 服务端地址。

详情页面并没有展示丰富的监控数据，这是因为没有将 spring-boot-admin-client 的端点数据暴露出来。

在 spring-boot-admin-client 中加入 actuator 的 Maven 依赖，代码如下所示。
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

然后在属性文件中追加下面的配置：
management.endpoints.web.exposure.include=*

management.endpoints.web.exposure.include：暴露所有的 actuator 端点信息重启 spring-boot-admin-client，我们就可以在详情页面看到更多的数据

如何在Admin中查看各个服务的日志
Spring Boot Admin 提供了基于 Web 页面的方式实时查看服务输出的本地日志，前提是服务中配置了 logging.file。

我们在 spring-boot-admin-client 的属性文件中增加下面的内容：
logging.file=/Users/zhangsan/Downloads/spring-boot-admin-client.log

重启服务，就可以在 Admin Server 的 Web 页面中看到新加了一个 Logfile 菜单
