• Turbine使用

    一、简介

    Turbine是聚合服务器发送事件流数据的一个工具，Hystrix的监控中，只能监控单个节点，实际生产中都为集群，因此可以通过Turbine来监控集群下Hystrix的metrics情况
    Turbine的github地址：https://github.com/Netflix/Turbine

    二、基本环境

    • 一个eureka模块
    • 两个消费者模块
    • 一个turbine监控模块

    三、创建eureka模块

    （1）创建项目

    创建一个spring boot项目

    （2）依赖

    （3）application.yml配置

    1.  
    2. server:
    3.   port: 9000
    4.  
    5. spring:
    6.   application:  # 指定微服务对外暴露的名称
    7.     name: 09-consumer-turbine-monitor-9000
    8.  
    9. eureka:
    10.   client:
    11.     service-url: # 指定Eureka服务注册中心
    12.       defaultZone: http://localhost:8000/eureka
    13.  
    14. # 开启Feign对Hystrix的支持
    15. feign:
    16.   hystrix:
    17.     enabled: true
    18.  
    19.   client:
    20.     config:
    21.       default:
    22.         connectTimeout: 5000  # 指定Feign连接提供者的超时时限
    23.         readTimeout: 5000    # 指定Feign从请求到获取提供者响应的超时时限
    24.  
    25. # 开启actuator的所有web终端
    26. management:
    27.   endpoints:
    28.     web:

    38.           thread:
    39.             timeoutInMilliseconds: 3000
    40. turbine:
    41.   app-config: abcmsc-consumer-depart01,abcmsc-consumer-depart02
    42.   cluster-name-expression: new String("default")

    44.   instanceUrlSuffix: /actuator/hystrix.stream #turbine默认监控actuator/路径下的端点，修改直接监控hystrix.stream
    45.     #cluster-name-expression: metadata['cluster']
    46.     #aggregator:
    47.   # cluster-config: ribbon
    48.   #instanceUrlSuffix:  /hystrix.stream #turbine默认监控actuator/路径下的端点，修改直接监控hystrix.stream

    （4）启动类

    1. package com.abc.consumer;
    2.  
    3. import org.springframework.boot.SpringApplication;
    4. import org.springframework.boot.autoconfigure.SpringBootApplication;
    5. import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    6. import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
    7. import org.springframework.cloud.netflix.turbine.EnableTurbine;
    8.  
    9.  
    10. @SpringBootApplication
    11. @EnableTurbine
    12. @EnableHystrixDashboard
    13. @EnableEurekaClient
    14. public class MonitorApplication {
    15.  
    16.     public static void main(String[] args) {
    17.         SpringApplication.run(MonitorApplication.class, args);
    18.     }
    19.  
    20.    /*@Bean
    21.     public ServletRegistrationBean getServlet() {
    22.         HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
    23.         ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
    24.         registrationBean.setLoadOnStartup(1);
    25.         registrationBean.addUrlMappings("/actuator/hystrix.stream);
    26.         registrationBean.setName("HystrixMetricsStreamServlet");
    27.         return registrationBean;
    28.     }*/
    29.  
    30. }

    七、启动

    （1）启动eureka模块

    （2）启动两个消费者模块

    （3）启动turbine监控模块

    八、效果

    （1）请求http://localhost:8080/consumer/depart/get/1

    （1）请求http://localhost:8081/consumer/depart/get/1

    浏览器访问http://localhost:9000/hystrix

    输入http://localhost:9000/turbine.stream
