Hystrix集群监控turbine

简介

Hystrix集群监控使用的是turbine，而turbine是基于Dashboard的

组建Hystrix集群

新建一个Module，该Module为Maven项目，命名为：microservice-student-provider-hystrix-1005，把microservice-student-provider-hystrix-1004的所有文件都复制一份过来，修改几个地方：

修改application.yml

server.port修改为：1005，eureka.instance.instance-id: microservice-student-hystrix修改为：1005

修改启动类

如果启动类是复制过来的，重命名为：StudentProviderHystrixApplication_1005

新建集群监控项目

新建一个Module，命名为：microservice-student-consumer-hystrix-turbine-91

继承父项目的依赖版本

application.yml配置

server:
  port: 91
  context-path: /

eureka:

      defaultZone: http://eureka2001.ledao.com:2001/eureka/,http://eureka2002.ledao.com:2002/eureka/,http://eureka2003.ledao.com:2003/eureka/

turbine:
  app-config: microservice-student   # 指定要监控的应用名称
  clusterNameExpression: "'default'" #表示集群的名字为default

spring:
  application:
    name: turbine

新建启动类

package com.ledao;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cloud.netflix.turbine.EnableTurbine;

/**
 * Hystrix集群监控启动类
 *
 * @author LeDao
 * @company
 * @create 2021-08-16 1:03
 */
@EnableTurbine
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class StudentConsumerTurbineApplication_91 {

    public static void main(String[] args) {
        SpringApplication.run(StudentConsumerTurbineApplication_91.class, args);
    }
}
