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);
}
}

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
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>
详细的监控数据
这里可以查看和更改环境变量
这里可以修改日志级别,会立即生效
