**Spring Boot Admin 是一个针对spring-boot的actuator接口进行UI美化封装的监控工具。**

添加 **@EnableAdminServer**

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

application.yml

server:
      port: 9001
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8081/eureka-server/eureka/
    spring:
      application:
        name: admin-server
      boot:
        admin:
          context-path: /monitor
    # turbine:
    # clusters: default
    # location: turbine
          routes:
            endpoints: env,metrics,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream
          monitor:
    # 更新应用信息的频率，单位毫秒
            period:  1000
    # 被监控的应用信息的过期时间,单位毫秒
            status-lifetime: 1000
    management:
      security:
        enabled: false
    endpoints:
      logfile:
    # 配置了 external-file 才能在监控页面上看到 Log 这一列
        external-file: C:\Users\市丸 银\AppData\Local\Temp\spring.log

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
    <configuration >
    
        <include resource="org/springframework/boot/logging/logback/base.xml"/>
        
        <jmxConfigurator/>
    
    </configuration>

**只要有服务注册到 Eureka 上，Spring Boot Admin 就能自动获取它的监控信息，无需多余的配置**

**注意：如果服务配置了server.context-path，一定还要配置下面2个，否则Spring Boot Admin无法获取该服务完整的监控数据(eureka server 会维护一份只读的服务清单返回给客户端，同时该缓存清单默认会每隔30s更新一次，metadataMap 中的信息会包含在清单里面)**

/** * Gets the metadata name/value pairs associated with this instance. This information * is sent to eureka server and can be used by other instances. */
         private Map<String, String> metadataMap = new HashMap<>();

eureka.instance.metadata-map.management.context-path=${server.context-path}
    eureka.instance.metadata-map.management.context-port=${server.port}

Spring Boot Admin 的监控页面

**Spring Boot Admin 有很多定时任务，当有新的服务注册到 Eureka了，会自动通知你，监控页面的信息也会自动更新**  
![这里写图片描述][70 1]

如果监控的服务使用了Hystrix，Spring Boot Admin只要添加依赖spring-boot-admin-server-ui-hystrix ，就可以监控到

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

![这里写图片描述][70 2]

详细的监控数据  
![这里写图片描述][70 3]  
![这里写图片描述][70 4]

这里可以查看和更改环境变量  
![这里写图片描述][70 5]

这里可以修改日志级别，会立即生效
