Spring Cloud Admin 实战

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/
