**监控模块**

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

**监控启动类**

@SpringBootApplication
    @EnableHystrixDashboard
    public class HystrixDashboardApplication {
        
      public static void main(String[] args) {
        SpringApplication.run(HystrixDashboardApplication.class, args);
      }
    }

输入
    http://localhost:8030/hystrix
    http://localhost:8020/user/hystrix.stream
    可以查看监控数据,6种情况

<dependencies>
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    
        <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    
        <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
    
        <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
      </dependencies>

**使用turbine聚合监控**

server:
      port: 8031
    spring:
      application:
        name: microservice-hystrix-turbine
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8761/eureka/
      instance:
        prefer-ip-address: true
    turbine:
      appConfig: microservice-consumer-order,
      microservice-consumer-order-feign-hystrix-fallback-stream
      clusterNameExpression: "'default'"

<dependencies>
        <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
        </dependency>
      </dependencies>

@SpringBootApplication
    @EnableTurbine
    public class TurbineApplication {
        
      public static void main(String[] args) {
        SpringApplication.run(TurbineApplication.class, args);
      }
    }
