Analysis of the implementation process of spring cloud turbine monitoring

This article mainly introduces the analysis of the implementation process of spring cloud turbine monitoring, which is introduced in great detail through the example code. It has a certain reference learning value for everyone’s study or work, and friends who need it can refer to it

}

3、 application.yml File configuration

server:
 port: 7016

spring:
 application:
  name: eureka-client-feign-hystrix-turbine
eureka:
 instance:
  hostname: localhost
  prefer-ip-address: true
  instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}}
 client:
  serviceUrl:
   defaultZone: http://${eureka.instance.hostname}:8761/eureka

Eureka provider: # remote service virtual host name
 ribbon:
  NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RoundRobinRule

#Turbo configuration
turbine:
 aggregator:
  cluster-config: default
 app-config: eureka-client-feign-hystrix-turbine,eureka-client-feign-hystrix,eureka-client-feign-hystrix-dashboard
 cluster-name-expression: "'default'"

4. Visit

　　a）http://localhost:7016/hystrix

b) On the dashboard, enter: http://localhost :7016/ turbine.stream
