## Spring Cloud Admin ##

**简介**

Spring Boot Admin 用于监控基于 Spring Boot 的应用，它是在 Spring Boot Actuator 的基础上提供简洁的可视化 WEB UI。Spring Boot Admin 提供了很多功能，如显示 name、id 和 version，显示在线状态，Loggers 的日志级别管理，Threads 线程管理，Environment 管理等。

**基于Cairo-SR3 和 Finchley.SR1**

在 Spring Boot 项目中，Spring Boot Admin 作为 Server 端，其他的要被监控的应用作为 Client 端，基于这种的配置如下步骤：

*  admin-server

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

application.yml:

server:
      port: 5000
    spring:
      application:
        name: admin-server
    eureka:
      client:
        service-url:
          defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/

pom:
