Spring Boot Admin-蒲公英云

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

  port: 9001

      defaultZone: http://localhost:8081/eureka-server/eureka/

    name: admin-server

      monitor:
# 更新应用信息的频率，单位毫秒
        period:  1000

        status-lifetime: 1000

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration >
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <!-- 开启JMX监控 -->
    <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
这里写图片描述

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

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>
