简介
上篇的hystrix dashboard只能断路监控一个微服务,本篇的turbine可以监控多个微服务,通过yml中配置app-config
即可监控该微服务的各个端口;

实战
1、创建《turbine-dashboard》模块
1.1、pom
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>turbine-dashboard</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>turbine-dashboard</name>

</dependency>
<!--turbine依赖-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-turbine</artifactId>
</dependency>
</dependencies>
</project>
1.2、yml
server:
port: 8061
spring:
application:
name: turbine-dashboard
eureka:
client:
service-url:
defaultZone: http://localhost:7000/eureka/
#支持turbine
turbine:
aggregator:
cluster-config: default
#监控的微服务
app-config: server-order
cluster-name-expression: new String("default")
1.3、application
《turbine-dashboard》的application声明注解@EnableTurbine
;
2、查看效果
1、以7002和7003端口启动《server-order》;
2、分别请求http://localhost:7002/testFeign和http://localhost:7003/testFeign;
3、打开http://localhost:8060/hystrix,输入http://localhost:8061/turbine.stream,点击Monitor Stream;
