SpringCloud(Hoxton.SR3)基础篇:第七章、Hystrix的Dashboard和Turbine使用

一 、turbine简介

  Hystrix Dashboard它主要用来实时监控Hystrix的各项指标信息。引入Turbine,通过它来汇集监控信息(多个微服务集群的hystrix.stream信息),并将聚合后的信息提供给Hystrix Dashboard来集中展示和监控。

 

二、项目介绍

  引入Turbine来聚合consumer-movie-ribbon-with-hystrix,consumer-movie-feign-with-hystrix服务的监控信息,并输出给Hystrix Dashboard来进行展示。

  相关微服务

  注意Feign获取hystrix.stream信息需要添加以下bean

    /**
     * 低版本直接启动即可使用 http://ip:port/hystrix.stream 查看监控信息
     * 高版本需要添加本方法方可使用 http://ip:port/actuator/hystix.stream 查看监控信息
     * 
     * @return
     */
    @Bean
    public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet() {
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean<HystrixMetricsStreamServlet> registrationBean = new ServletRegistrationBean<HystrixMetricsStreamServlet>(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }

 

三、Turbine和Dashboard搭建

  (1) pom.xml引入依赖

        <!-- turbine依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
        </dependency>
        <!-- dashboard依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

 

  (2)application.yml配置

server:
   port: 8030
spring:
   application:
      name: springcloud-hystrix-turbine
#eureka相关配置
eureka:
   client:
      service-url:
         defaultZone: http://user:password123@localhost:8761/eureka
   instance:
      prefer-ip-address: true
#Turbine相关配置
turbine:
   aggregator:
      clusterConfig: default
   appConfig: consumer-movie-ribbon-with-hystrix,consumer-movie-feign-with-hystrix
   clusterNameExpression: "'default'"  #new String("default")

 

  (3)springboot启动类

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
//启用Dashboard注解
@EnableHystrixDashboard
//启用Turbine注解
@EnableTurbine
public class HystrixTurbineApplication {
    public static void main(String[] args) {
        SpringApplication.run(HystrixTurbineApplication.class, args);
    }
}

 

  (4)启动测试

  • 启动eureka
  • 启动provider-user微服务
  • 启动consumer-movie-feign-with-hystrix启动两个服务,端口(8040)、端口(8041)用来模拟集群
  • 启动consumer-movie-ribbon-with-hystrix启动两个服务,端口(8010)、端口(8011)用来模拟集群
  • 启动springcloud-hystrix-turbine服务

  全部服务启动成功,eureka界面如下

 

 

  

  测试单个服务的hystrix.stream数据获取浏览器输入:http://localhost:8040/actuator/hystrix.stream

  ps:浏览器用chrome,用Microsoft Edge浏览器(win10)会直接下载文件。获取数据成功截图

 

 

 

 

  测试turbine,浏览器输入:http://localhost:8030/turbine.stream

 

 

 

  浏览器输入: http://localhost:8030/hystrix 打开Dashboard界面,输入turbine收集地址http://localhost:8030/turbine.stream

 

 

 

  点击Monitor Stream按钮,若是不统计对应节点,显示图表,可能是未进行服务访问调用。到各个消费者服务(ribbon,feign)进行服务调用例如:http://localhost:8010/movie/3

  

  各个指标的含义参见下图。

 

 

 

 

 

四、修改context-path导致hystrix.stream地址变更

  相关修改内容如下

  (1)新建服务consumer-movie-ribbon-with-hystrix2,修改application.yml

server:
  port: 8011
  #增加context-path访问路径   地址变为  http://localhost:8011/ribbon/movie/1
  servlet:
     context-path: /ribbon

  (2)新建springcloud-hystrix-turbine2,修改application.yml,测试时为单个微服务

#Turbine相关配置
turbine:
   aggregator:
      clusterConfig: CONSUMER-MOVIE-RIBBON-WITH-HYSTRIX2
   appConfig: consumer-movie-ribbon-with-hystrix2
   #修改turbine访问微服务hystrix.stream的路径
   instanceUrlSuffix:
      CONSUMER-MOVIE-RIBBON-WITH-HYSTRIX2: ribbon/actuator/hystrix.stream

 

  (3)测试结果

  测试服务:http://localhost:8011/ribbon/movie/3

 

 

   测试Hystrix.stream地址:http://localhost:8011/ribbon/actuator/hystrix.stream

 

 

   测试turbine,地址:http://localhost:8030/turbine.stream?cluster=CONSUMER-MOVIE-RIBBON-WITH-HYSTRIX2。用dashboard展示

 

 

 

 

 

五、独立hystrix.stream数据获取端口

  相关修改内容如下

  (1)新建服务consumer-movie-ribbon-with-hystrix3,修改application.yml.添加management.server.port配置.

server:
  port: 8011
  #增加context-path访问路径   地址变为  http://localhost:8011/ribbon/movie/1
  servlet:
     context-path: /ribbon
spring:
  application:
      name: consumer-movie-ribbon-with-hystrix3
#eureka客户端连接配置
eureka:
   client:
      healthcheck:
         enabled: true
      service-url:
      #注册中心地址
         defaultZone: http://user:password123@localhost:8761/eureka
   instance:
      #将ip注册到eureka上
      prefer-ip-address: true
      #微服务向eureka注册实例名${spring.cloud.client.ip-address} 表示ip地址 spring2.0以上为ip-address
      instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${spring.application.instance_id:${server.port}}
      #修改home-page-url-path告诉eureka更改homepageUrlPath路径为 localhost:8011/ribbon
      home-page-url-path: /ribbon
#开放health,info,hystrix.stream页面路径访问 http://localhost:8011/actuator/hystrix.stream
#spring-boot-starter-acturator
management:
  server:
     port: 8081
  endpoints: 
    web: 
      exposure: 
        include: health,info,hystrix.stream #根据需求增删路径

  (3)新建springcloud-hystrix-turbine3,修改application.yml,测试时为单个微服务

server:
   port: 8030
spring:
   application:
      name: springcloud-hystrix-turbine3
#eureka相关配置
eureka:
   client:
      service-url:
         defaultZone: http://user:password123@localhost:8761/eureka
   instance:
      prefer-ip-address: true
#Turbine相关配置
turbine:
   aggregator:
      clusterConfig: CONSUMER-MOVIE-RIBBON-WITH-HYSTRIX3
   appConfig: consumer-movie-ribbon-with-hystrix3
#显示日志
logging: 
  level:
    root: INFO
    com.netflix.turbine.monitor: DEBUG

 

  (4)测试

  测试服务:http://localhost:8011/ribbon/movie/3

  测试Hystrix.stream地址:http://localhost:8081/actuator/hystrix.stream

 

 

 

  

   测试turbine,地址:http://localhost:8030/turbine.stream?cluster=CONSUMER-MOVIE-RIBBON-WITH-HYSTRIX3。用dashboard展示
