SpringCloud之熔断监控HystrixDashboard和Turbine

Hystrix-dashboard是一款针对Hystrix进行实时监控的工具，通过Hystrix Dashboard我们可以在直观地看到各

Hystrix Command的请求响应时间, 请求成功率等数据。但是只使用Hystrix Dashboard的话, 你只能看到单个应

用内的服务信息，这明显不够。我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix

Dashboard上，这个工具就是Turbine。

1、Hystrix Dashboard

我们在熔断示例项目的基础上更改。

1.2 启动类

启动类添加启用Hystrix Dashboard和熔断器

package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
@EnableHystrixDashboard
@EnableCircuitBreaker
public class SpringCloudConsumerHystrixDashboardApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringCloudConsumerHystrixDashboardApplication.class, args);
    }
}

1.3 其它类

package com.example.remote;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
@FeignClient(name= "spring-cloud-producer", fallback = HelloRemoteHystrix.class)
public interface HelloRemote {
    @RequestMapping(value = "/hello")
    public String hello(@RequestParam(value = "name") String name);
}
package com.example.remote;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestParam;
@Component
public class HelloRemoteHystrix implements HelloRemote{
    @Override
    public String hello(@RequestParam(value = "name") String name) {
        return "hello " +name+", this messge send failed ";
    }
}
package com.example.controller;
import com.example.remote.HelloRemote;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ConsumerController {
    @Autowired
    HelloRemote hejavascriptlloRemote;
    @RequestMapping("/hello/{name}")
    public String index(@PathVariable("name") String name) {
        return helloRemote.hello(name);
    }
}
spring.application.name=spring-cloud-consumer-hystrix-dashboard
server.port=9003
feign.hystrix.enabled=true
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

1.4 测试

启动工程后访问 http://localhost:9003/hystrix，将会看到如下界面：

SpringCloud中的熔断监控HystrixDashboard和Turbine示例详解

图中会有一些提示：

Cluster via Turbine (default cluster): http://turbine-hostname:port/turbine.stream

Cluster via Turbine (custom cluster): http://turbine-hostname:port/turbine.stream?cluster=[clusterName]

Single Hystrix App: http://hystrix-app:port/hystrix.stream

大概意思就是如果查看默认集群使用第一个url，查看指定集群使用第二个url，单个应用的监控使用最后一个，我

们暂时只演示单个应用的所以在输入框中输入： http://localhost:9003/hystrix.stream ，输入之后点击

monitor，进入页面。如果没有请求会先显示Loading ...：

访问 http://localhost:9003/hystrix.stream 也会不断的显示ping。

请求服务 http://localhost:9003/hello/neo，就可以看到监控的效果了：

SpringCloud中的熔断监控HystrixDashboard和Turbine示例详解

首先访问 http://localhost:9003/hystrix.stream，显示如下：

data: {"type":"HystrixCommand","name":"HelloRemote#hello(String)","group":"spring-cloud-producer","currentTime":1662554090588,"isCircuitBreakerOpen":false,"errorPercentage":0,"errorCount":0,"requestCount":0,"rollingCountBadRequests":0,"rollingCountCollapsedRequests":0,"rollingCountEmit":0,"rollingCountExceptionsThrown":0,"rollingCountFailure":0,"rollingCountFallbackEmit":0,"rollingCountFallbackFailure":0,"rollingCountFallbackMissing":0,"rollingCountFallbackRejection":0,"rollingCountFallbackSuccess":0,"rollingCountResponsesFromCache":0,"rollingCountSemaphoreRejected":0,"rollingCountShortCircuited":0,"rollingCountSuccess":0,"rollingCountThreadPoolRejected":0,"rollingCountTimeout":0,"currentConcurrentExecutionCount":0,"rollingMaxConcurrentExecutionCount":0,"latencyExecute_mean":0,"latencyExecute":{"0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0}php,"latencyTotal_mean":0,"latencyTotal":{"0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0},"propertyValue_circuitBreakerRequestVolumeThreshold":20,"propertyValue_circuitBreakerSleepWindowInMilliseconds":5000,"propertyValue_circuitBreakerErrorThresholdPercentage":50,"propertyValue_circuitBreakerForceOpen":false,"propertyValue_circuitBreakerForceClosed":false,"propertyValue_circuitBreakerEnabled":true,"propertyValue_executionIsolationStrategy":"THREAD","propertyValue_executionIsolationThreadTimeoutInMilliseconds":1000,"propertyValue_executionTimeoutInMilliseconds":1000,"propertyValue_executionIsolationThreadInterruptOnTimeout":true,"propertyValue_executionIsolationThreadPoolKeyOverride":null,"propertyValue_executionIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_fallbackIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"propertyValue_requestCacheEnabled":true,"propertyValue_requestLogEnabled":true,"reportingHosts":1,"threadPool":"spring-cloud-producer"}
data: {"type":"HystrixThreadPool","name":"spring-cloud-producer","currentTime":1662554090588,"currentActiveCount":0,"currentCompletedTaskCount":1,"currentCorePoolSize":10,"currentLargestPoolSize":1,"currentMaximumPoolSize":10,"currentPoolSize":1,"currentQueueSize":0,"currentTaskCount":1,"rollingCountThreadsExecuted":0,"rollingMaxActiveThreads":0,"rollingCountCommandRejections":0,"propertyVjsalue_queueSizeRejectionThreshold":5,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"reportingHosts":1}
ping:

说明已经返回了监控的各项结果。

到监控页面就会显示如下图：

SpringCloud中的熔断监控HystrixDashboard和Turbine示例详解

其实就是 http://localhost:9003/hystrix.stream 返回结果的图形化显示，Hystrix Dashboard Wiki上详细

说明了图上每个指标的含义，如下图：

SpringCloud中的熔断监控HystrixDashboard和Turbine示例详解

到此单个应用的熔断监控已经完成。

2、Turbine

在复杂的分布式系统中，相同服务的节点经常需要部署上百甚至上千个，很多时候，运维人员希望能够把相同服务

的节点状态以一个整体集群的形式展现出来，这样可以更好的把握整个系统的状态。 为此，Netflix提供了一个开

源项目（Turbine）来提供把多个hystrix.stream的内容聚合为一个数据源供Dashboard展示。

2.1 添加依赖

2.2 配置文件

spring.application.name=hystrix-dashboard-turbine
server.port=8001
turbine.appConfig=node01,node02
turbine.aggregator.clusterConfig= default
turbine.clusterNameExpression= new String("default")
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/
  • turbine.appConfig：配置Eureka中的serviceId列表，表明监控哪些服务。
  • turbine.aggregator.clusterConfig：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。

  • turbine.clusterNameExpression ：

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

2.3 启动类

启动类添加@EnableTurbine，激活对Turbine的支持

package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;
@SpringBootApplication
@EnableHystrixDashboard
@EnableTurbine
public class SpringCloudHystrixDashboardTurbineApplication {
	public static void main(String[] args) {
		SpringApplication.run(SpringCloudHystrixDashboardTurbineApplication.class, args);
	}
}

到此Turbine（hystrix-dashboard-turbine）配置完成

2.4 测试

在示例项目spring-cloud-consumer-hystrix基础上修改为两个服务的调用者spring-cloud-consumer-node1和

spring-cloud-consumer-node2。

spring-cloud-consumer-node1项目改动如下：application.properties文件内容

spring.application.name=node01
server.port=9001
feign.hystrix.enabled=true
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

spring-cloud-consumer-node2项目改动如下：application.properties文件内容

spring.application.name=node02
server.port=9002
feign.hystrix.enabled=true
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

HelloRemote类修改：

package com.example.remote;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
@FeignClient(najsme = "spring-cloud-producer", fallback = HelloRemoteHystrix.class)
public interface HelloRemote {
    @RequestMapping(value = "/hello")
    public String hello(@RequestParam(value = "name") String name);
}

对应的HelloRemoteHystrix和ConsumerController类跟随修改，具体查看代码

package com.example.remote;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestParam;
@Component
public class HelloRemoteHystrix implements HelloRemote{
    @Override
    public String hello(@RequestParam(value = "name") String name) {
        return "hello " +name+", this messge send failed ";
    }
}
package com.example.controller;
import com.example.remote.HelloRemote;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ConsumerController {
    @Autowired
    HelloRemote helloRemote;
    @RequestMapping("/hello/{name}")
    public String index(@PathVariable("name") String name) {
        return helloRemote.hello(name);
    }
}

修改完毕后，依次启动spring-cloud-eureka、spring-cloud-consumer-node1、spring-cloud-consumer-

node2、spring-cloud-hystrix-dashboard-turbine

打开eureka后台可以看到注册了三个服务：

SpringCloud中的熔断监控HystrixDashboard和Turbine示例详解

访问 http://localhost:8001/turbine.stream

返回：

: ping
data: {"reportingHostsLast10Seconds":0,"name":"meta","type":"meta","timestamp":1662554703162}
: ping
data: {"reportingHostsLast10Seconds":0,"name":"meta","type":"meta","timestamp":1662554706172}

并且会不断刷新以获取实时的监控数据，说明和单个的监控类似，返回监控项目的信息。

进行图形化监控查看，输入：http://localhost:8001/hystrix，返回酷酷的小熊界面
