Turbine——Hystrix集群监控

一、Hystrix Turbine简介
看单个的Hystrix Dashboard的数据并没有什么多大的价值，要想看多个系统或集群系统的Hystrix Dashboard数据就需要用到Hystrix Turbine。Hystrix Turbine将每个服务Hystrix Dashboard数据进行了整合。Hystrix Turbine的使用非常简单，只需要引入相应的依赖和加上注解和配置就可以了。

二、准备工作
因为我们需要监控多个服务的Dashboard，所以需要搭建一个Turbine服务来聚合监控 Hystrix 断路器，取名为spring-cloud-hystrix-turbine。了解springcloud架构可以加求求：三五三六二四七二五九

三、创建spring-cloud-hystrix-turbine
1、引入pom依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
        <dependency>

                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>
</project>

 2、配置文件application.yml

spring:
  application:
    name: spring-cloud-hystrix-turbine
  cloud:
    consul:
      discovery: 
        prefer-ip-address: true
        instanceId: ${spring.application.name}:${server.port}
      host: localhost
      port: 8500
server:
  port: 8810
turbine:
  aggregator:
    #监控所有微服务集群
    #hytrix仪表盘：http://localhost:8810/hystrix/
    #监控地址：http://localhost:8810/turbine.stream
    #在hystrix仪表盘中监控上面的地址即可
    clusterConfig: default
  #要监控的微服务serviceId   
  appConfig: mcc-feign-hystrix,mcc-ribbon-hystrix,mcc-ribbon-hystrix-propagating
  clusterNameExpression: "'default'"

 3、TurbineApplication——Turbine入口程序

package com.lynch.consumer.turbine;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;

@SpringBootApplication
//开启Turbine支持,用来进行集群监控
@EnableTurbine
//开启Hystrix仪表盘
@EnableHystrixDashboard
public class TurbineApplication {
    public static void main(String[] args) {
        SpringApplication.run(TurbineApplication.class, args);
    }
}

 四、Turbine演示

依次开启mcc-feign-hystrix、mcc-ribbon-hystrix、mcc-ribbon-hystrix-propagating、spring-cloud-hystrix-turbine工程。

打开浏览器输入：http://localhost:8810/turbine.stream，界面如下：

依次多次请求：
http://localhost:8807/ribbon/get/aa

http://localhost:8808/feign1/get/aa

hystrix断路器生效。

打开:http://localhost:8810/hystrix/，输入监控流http://localhost:8810/turbine.stream

点击monitor stream 进入页面：

可以看到这个页面聚合了2个service的hystrix dashbord数据。
