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:
