21、断路器集群监控Turbine

前几篇已经实现了对单个服务实例的监控,当然在实际应用中,单个实例的监控数据没有多大的价值,我们其实更需要的是一个集群系统的监控信息,这时就需要引入TurbineTurbine能够汇集监控信息,并将聚合后的信息提供给Hystrix Dashboard来集中展示和监控。

       本文将结合之前学习的注册中心Eureka、服务提供者Provider、断路器Hystrix和仪表盘Dashboard,学习断路器集群监控Turbine最终整体架构如下:

 

 

 

项目说明:

注册中心:sc-eureka-server

服务提供者:sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2

服务消费者、断路器:sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2

集群监控、仪表盘:sc-client-turbine-hystrix

 

1、 注册中心项目sc-eureka-server参考《eureka注册中心单机》

2、 服务提供者项目sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2由项目sc-eureka-client-provider改造而来。

sc-server-turbine-hystrix-dashboard-node1:

 

 

 

 

sc-server-turbine-hystrix-dashboard-node2

 

 

 

 

3、 服务消费者、断路器项目sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2由项目sc-feign-hystrix-dashboard改造而来。

sc-client-turbine-hystrix-dashboard-node1

(1) bootstrap.yml修改

 

server:

  port: 5801

 

 

(2) application.yml文件修改

 

 

 

3)去掉springcloud启动类的EnableHystrixDashboard注解

 

sc-client-turbine-hystrix-dashboard-node2

1bootstrap.yml修改

 

server:

  port: 5802

 

 

2application.yml文件修改

 

 

 

(3) 去掉springcloud启动类的EnableHystrixDashboard注解

 

注: turbine只能监控Hystrix服务。不是Hystrix的服务不能监控。所以配置文件都配置了如下配置项

 

 

 

 

4、 新建集群监控、仪表盘项目sc-client-turbine-hystrix,对应的pom.xml文件如下

5、 新建配置文件application.yml

 

spring:

  application:

    name: sc-client-turbine-hystrix

 

eureka:

  client:

    registerWithEureka: true #是否将自己注册到Eureka服务中,默认为true

    fetchRegistry: true #是否从Eureka中获取注册信息,默认为true

    serviceUrl:

      defaultZone: http://localhost:5001/eureka/

        

server:

  port: 9091

  

turbine:

  appConfig: sc-client-turbine-hystrix-dashboard-node1,sc-client-turbine-hystrix-dashboard-node2 # 配置Eureka中的serviceId列表,表明监控哪些服务

  clusterNameExpression: new String("default")

  # 1. clusterNameExpression指定集群名称,默认表达式appName;此时:turbine.aggregator.clusterConfig需要配置想要监控的应用名称

  # 2. 当clusterNameExpression: default时,turbine.aggregator.clusterConfig可以不写,因为默认就是default

  # 3. 当clusterNameExpression: metadata['cluster']时,假设想要监控的应用配置了eureka.instance.metadata-map.cluster: ABC,则需要配置,同时turbine.aggregator.clusterConfig: ABC

  instanceUrlSuffix: /hystrix.stream

  aggregator:

    clusterConfig: default  # 指定聚合哪些集群,多个使用","分割,默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问

 

 

6、 新建springboot启动类

 

package sc.client.turbine;

 

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

import org.springframework.cloud.netflix.turbine.EnableTurbine;

 

@SpringBootApplication

@EnableHystrixDashboard

@EnableTurbine

@EnableEurekaClient

public class TurbineApplication {

 

public static void main(String[] args) {

  SpringApplication.run(TurbineApplication.class, args);

}

 

}

 

 

 

7、 按照如下先后顺序启动项目

1sc-eureka-server

2sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2

3sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2

4sc-client-turbine-hystrix

 

8、 访问注册中心http://127.0.0.1:5001/确认服务都启动成功

 

 

 

9、 验证Turbine集群监控

访问http://localhost:9091/turbine.stream,返回如下数据

 

 

 

并且会不断刷新以获取实时的监控数据,说明单个的监控类似,返回监控项目的信息。进行图形化监控查看,输入http://localhost:9091/hystrix,返回如下界面

 

 

 

 输入 http://localhost:9091/turbine.stream,然后点击 Monitor Stream ,可以看到出现如下界面

 

 

没有出现任何监控图表。分别访问http://127.0.0.1:5801/feign/user/getUser/1http://127.0.0.1:5802/feign/user/listUser(尽量多访问几次)

 

 

 

 

 

 

 

 

返回查看Turbine集群监控图表界面
