  • 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

     

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </parent>
    
     
    
    <dependencyManagement>
    
    <dependencies>
    
    <dependency>

    <!-- <dependency>

        <version>1.4.5.RELEASE</version>
    
    </dependency> -->
    
     
    
    <dependency>
    
        <groupId>org.springframework.cloud</groupId>

    </dependency>
    
    </dependencies>
    
    </project>
    
     

     

    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
