使用Spring Boot Actuator Endpoint监控应用程序有点困难。因为，如果有’n’个应用程序，每个应用程序都有单独的执行器端点，从而使监控变得困难。Spring Boot Admin Server是一个用于管理和监控Microservice应用程序的程序。要处理这种情况，CodeCentric Team提供了一个Spring Boot Admin UI，用于在一个地方管理和监控所有Spring Boot应用程序Actuator端点。要构建Spring Boot Admin Server，需要在构建配置文件中添加以下依赖项。Maven用户可以在pom.xml 文件中添加以下依赖项 -

<dependency>
   <groupId>de.codecentric</groupId>
   <artifactId>spring-boot-admin-server</artifactId>
   <version>1.5.5</version>
</dependency>
<dependency>
   <groupId>de.codecentric</groupId>
   <artifactId>spring-boot-admin-server-ui</artifactId>
   <version>1.5.5</version>
</dependency>

在主Spring Boot应用程序类文件中添加@EnableAdminServer注解。@EnableAdminServer注解用于使管理服务器监视所有其他微服务。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import de.codecentric.boot.admin.config.EnableAdminServer;

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

现在，在application.properties文件中定义server.port和application.name

server.port = 9090
spring.application.name = adminserver

对于Maven用户，完整的构建文件 - pom.xml 内容如下:

<?xml version = "1.0" encoding = "UTF-8"?>

   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

      </plugins>
   </build>

</project>

现在，使用下面给出的命令运行JAR文件 -
