Turbine AMQP 不接收 Hystrix 流 [英] Turbine AMQP does not receive Hystrix stream
本文介绍了Turbine AMQP 不接收 Hystrix 流的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个 Turbine 和 Hystrix 设置工作，但决定将其更改为 Turbine AMQP，以便我可以将多个服务聚合到一个流/仪表板中.
I had a Turbine and Hystrix setup working, but decided to change it over to Turbine AMQP so I could aggregate multiple services into one stream/dashboard.
我已经设置了一个在 localhost:8989 上运行的 Turbine AMQP 服务器，但它似乎没有从客户端服务获取 Hystrix 数据.当我在浏览器中点击 Turbine 服务器的 IP 时，我会反复看到 data: {"type":"Ping"} ，即使我正在轮询 Hystrix 的 URL.如果我尝试在 Hystrix 仪表板中显示 Turbine AMQP 流，我会得到:无法连接到命令指标流.
I have set up a Turbine AMQP server running on localhost:8989, but it doesn't appear to be getting Hystrix data from the client service. When I hit the Turbine server's IP in my browser, I see data: {"type":"Ping"} repeatedly, even while I am polling the URL of the Hystrix. If I attempt to show the Turbine AMQP stream in the Hystrix Dashboard, I get: Unable to connect to Command Metric Stream.
我在端口 5672 上默认安装了 RabbitMQ.
I have a default install of RabbitMQ running on port 5672.
我使用 Hystrix-AMQP 的客户端服务有一个如下所示的 application.yml 文件:
My client service using Hystrix-AMQP has a application.yml file that looks like so:
spring:
application:
name: policy-service
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
rabbitmq:
addresses: ${vcap.services.${PREFIX:}rabbitmq.credentials.uri:amqp://${RABBITMQ_HOST:localhost}:${RABBITMQ_PORT:5672}}
启动日志的尾部是这样的:
The tail end of the startup log looks like this:

所以看起来 PolicyService 成功连接到消息代理.
So it looks like PolicyService successfully connects to the message broker.

知道为什么 Turbine AMQP 服务器没有接收来自 Hystrix AMQP 客户端的通信吗?
Any ideas why the Turbine AMQP server is not receiving communication from the Hystrix AMQP client?
Turbine-AMQP 主要看起来像:
Turbine-AMQP main looks like:
package com.turbine.amqp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.turbine.amqp.EnableTurbineAmqp;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@EnableTurbineAmqp
@EnableDiscoveryClient
public class TurbineAmqpApplication {
public static void main(String[] args) {
SpringApplication.run(TurbineAmqpApplication.class, args);
}
}
这是它的 application.yml:
Here's its application.yml:
server:
port: 8989
spring:
rabbitmq:
addresses: ${vcap.services.${PREFIX:}rabbitmq.credentials.uri:amqp://${RABBITMQ_HOST:localhost}:${RABBITMQ_PORT:5672}}
点击http://localhost:8989/turbine.stream 产生一个重复的数据流:{"type":"Ping"}
并在控制台中显示:

我对 Turbo-amqp 的依赖如下:
My dependencies for turbine-amqp are as follows:
dependencies {
compile('org.springframework.cloud:spring-cloud-starter-turbine-amqp:1.0.3.RELEASE')
compile 'org.springframework.boot:spring-boot-starter-web:1.2.5.RELEASE'
compile 'org.springframework.boot:spring-boot-starter-actuator:1.2.5.RELEASE'
testCompile("org.springframework.boot:spring-boot-starter-test")
}
dependencyManagement {
imports {
mavenBom 'org.springframework.cloud:spring-cloud-starter-parent:1.0.2.RELEASE'
}
}
推荐答案
很难找到解决方案.
使用 Spring cloud 2.1.4.RELEASE 我遇到了类似的问题.
Using Spring cloud 2.1.4.RELEASE I faced with similar problem.
主要原因是rabbitMQ中的[exchanges]名称不兼容:spring-cloud-netflix-hystrix-stream 和 spring-cloud-starter-netflix-turbine-stream.
The main cause is the incompatibility [exchanges] name in rabbitMQ between: spring-cloud-netflix-hystrix-stream and spring-cloud-starter-netflix-turbine-stream.
所以解决它:启动服务组件时查看名称创建的交换名称{同声明hystrix-stream}
So solve it: See the name created exchange name when you start the service componente {the same that declare hystrix-stream}
在声明 {turbine-stream} 的组件上更新属性
on the componente that declare {turbine-stream} update the property
turbine.stream.destination=
turbine.stream.destination=
就我而言Turbo.stream.destination=hystrixStreamOutput
in my case turbine.stream.destination=hystrixStreamOutput
这篇关于Turbine AMQP 不接收 Hystrix 流的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
