Question

我有一个涡轮机的实现，能够通过Eureka发现运行服务：

2015-09-08 11:40:13.727  INFO 13112 --- [        Timer-0] o.s.c.n.turbine.EurekaInstanceDiscovery  : Fetching instance list for apps: [policy-service]
2015-09-08 11:40:13.727  INFO 13112 --- [        Timer-0] o.s.c.n.turbine.EurekaInstanceDiscovery  : Fetching instances for app: policy-service
2015-09-08 11:40:13.727  INFO 13112 --- [        Timer-0] o.s.c.n.turbine.EurekaInstanceDiscovery  : Received instance list for app: policy-service, size=1
2015-09-08 11:40:13.727  INFO 13112 --- [        Timer-0] c.n.t.discovery.InstanceObservable       : Retrieved hosts from InstanceDiscovery: 1
2015-09-08 11:40:13.728  INFO 13112 --- [        Timer-0] c.n.t.discovery.InstanceObservable       : Found hosts that have been previously terminated: 0
2015-09-08 11:40:13.728  INFO 13112 --- [        Timer-0] c.n.t.discovery.InstanceObservable       : Hosts up:1, hosts down: 0

Hystrix正在客户端应用程序策略服务上运行。我能够在hystrix仪表板中查看其流并查看它。

问题在于，当我查看Turbine流时，我得到了这个：

: ping
data: {"reportingHostsLast10Seconds":0,"name":"meta","type":"meta","timestamp":1441734488823}

当我在带有http://localhost:8095/turbine.stream?cluster=DEV的Hystrix仪表板中查看它时，我只看到＆＃34;正在加载......＆＃34;

我已尝试在this帖子中提到的所有内容都无济于事。

这是我的涡轮机服务＆＃39; application.yml：

turbine:
  aggregator:
    clusterNameExpression: new String("default")
    clusterConfig: DEV
    #http://localhost:8095/turbine.stream?cluster=DEV
  appConfig: policy-service
  InstanceMonitor:
    eventStream:
      skipLineLogic:
        enabled: false

我在没有clusterConfig且没有clusterNameExpression的情况下尝试了这个。

这是我的bootstrap.yml：

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
spring:
  application:
    name: turbine-service
server:
  port: 8095

这是我的来源：

package com.ml.turbine;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.turbine.EnableTurbine;

@SpringBootApplication
@EnableTurbine
@EnableEurekaClient
public class TurbineService {

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

当我在浏览器中点击我的涡轮流时，日志显示为：

为什么当我的涡轮机流连接到策略服务并且hystrix流按预期工作时，我什么也得不到？

Answer 1

事实证明我的application.yml配置错误。

来自here：

clusterName可以通过turbine.clusterNameExpression中的SPEL表达式进行自定义，其中root用户是InstanceInfo的实例。默认值为appName，这意味着Eureka serviceId最终作为群集密钥（即客户的InstanceInfo的appName为“CUSTOMERS”）。

我的application.yml现在看起来像这样：

turbine:
  aggregator:
    clusterNameExpression: new String("default")
    clusterConfig: POLICY-SERVICE
    #http://localhost:8095/turbine.stream?cluster=POLICY-SERVICE
  appConfig: policy-service

Spring boot，eureka，hystrix，turbine：turbine总是显示0个报告主机
