SpringCloud的Hystrix Dashboard、Turbine的配置

• • 搭建Hystrix Dashboard
  • • 命令行启动访问(运行于httpd软件上)
  • Turbine
  • • Turbine配置

1. 新建spring模块：sp07-hystrix-dashboard
2. 配置pom.xml。添加 Hystrix Dashboard

                org.springframework.cloud
                spring-cloud-starter-netflix-hystrix-dashboard

3. yml配置允许抓取的服务器列表

#eureka 2001,   zuul 3001, hystrix dashboard 4001
server:
  port: 4001
hystrix:
  dashboard:
    #允许抓取日志的服务列表
    proxy-stream-allow-list: localhost

4. 启动类添加注解：@EnableHystrixDashboard
5. 访问路径：http://localhost:4001/hystrix

ab -n 20000 -c 50 http://localhost:3001/item-service/sakjfh464564?token=safd5464
ab -n 20000 -c 50 http://localhost:3001/user-service/8

从多台服务器抓取Hystrix日志，进行聚合， hystrix dashboard从Turbine抓取聚合后的日志数据

1. 新建spring模块：sp08-turbine
2. pom.xml：添加Turbine，eureka client

            org.springframework.cloud
            spring-cloud-starter-netflix-eureka-client
        
        
            org.springframework.cloud
            spring-cloud-starter-netflix-turbine
 

3. yml配置

spring:
  application:
    name: turbine
server:
  port: 5001
eureka:
  client:
    service-url:
      defaultZone: http://eureka1:2001/eureka,http://eureka2:2002/eureka
turbine:
  app-config: zuul
  cluster-name-expression: new String("default")

4. 启动类注解：@EnableTurbine
5. 访问http://localhost:5001/turbine.stream
