HystrixDashboard是用于實(shí)時(shí)監(jiān)控Hystrix性能的工具,展示請(qǐng)求響應(yīng)時(shí)間和成功率等數(shù)據(jù),本文介紹了如何配置和使用HystrixDashboard和Turbine進(jìn)行熔斷監(jiān)控,包括依賴(lài)添加、啟動(dòng)類(lèi)配置和測(cè)試流程,感興趣的朋友一起看看吧

SpringCloud之熔斷監(jiān)控HystrixDashboard和Turbine

Hystrix-dashboard是一款針對(duì)Hystrix進(jìn)行實(shí)時(shí)監(jiān)控的工具，通過(guò)Hystrix Dashboard我們可以在直觀地看到各

Hystrix Command的請(qǐng)求響應(yīng)時(shí)間, 請(qǐng)求成功率等數(shù)據(jù)。但是只使用Hystrix Dashboard的話, 你只能看到單個(gè)應(yīng)

用內(nèi)的服務(wù)信息，這明顯不夠。我們需要一個(gè)工具能讓我們匯總系統(tǒng)內(nèi)多個(gè)服務(wù)的數(shù)據(jù)并顯示到Hystrix

Dashboard上，這個(gè)工具就是Turbine。

1.2 啟動(dòng)類(lèi)

啟動(dòng)類(lèi)添加啟用Hystrix Dashboard和熔斷器

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 其它類(lèi)

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 helloRemote;
    @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 測(cè)試

啟動(dòng)工程后訪問(wèn) http://localhost:9003/hystrix，將會(huì)看到如下界面：

圖中會(huì)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認(rèn)集群使用第一個(gè)url，查看指定集群使用第二個(gè)url，單個(gè)應(yīng)用的監(jiān)控使用最后一個(gè)，我

們暫時(shí)只演示單個(gè)應(yīng)用的所以在輸入框中輸入： http://localhost:9003/hystrix.stream ，輸入之后點(diǎn)擊

monitor，進(jìn)入頁(yè)面。如果沒(méi)有請(qǐng)求會(huì)先顯示Loading ...：

在這里插入圖片描述

訪問(wèn) http://localhost:9003/hystrix.stream 也會(huì)不斷的顯示ping。

在這里插入圖片描述

請(qǐng)求服務(wù) http://localhost:9003/hello/neo，就可以看到監(jiān)控的效果了：

在這里插入圖片描述

首先訪問(wèn) http://localhost:9003/hystrix.stream，顯示如下：

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},"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,"propertyValue_queueSizeRejectionThreshold":5,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"reportingHosts":1}
ping:

說(shuō)明已經(jīng)返回了監(jiān)控的各項(xiàng)結(jié)果。

到監(jiān)控頁(yè)面就會(huì)顯示如下圖：

在這里插入圖片描述

其實(shí)就是 http://localhost:9003/hystrix.stream 返回結(jié)果的圖形化顯示，Hystrix Dashboard Wiki上詳細(xì)

說(shuō)明了圖上每個(gè)指標(biāo)的含義，如下圖：

在這里插入圖片描述

到此單個(gè)應(yīng)用的熔斷監(jiān)控已經(jīng)完成。

2、Turbine

在復(fù)雜的分布式系統(tǒng)中，相同服務(wù)的節(jié)點(diǎn)經(jīng)常需要部署上百甚至上千個(gè)，很多時(shí)候，運(yùn)維人員希望能夠把相同服務(wù)

的節(jié)點(diǎn)狀態(tài)以一個(gè)整體集群的形式展現(xiàn)出來(lái)，這樣可以更好的把握整個(gè)系統(tǒng)的狀態(tài)。 為此，Netflix提供了一個(gè)開(kāi)

源項(xiàng)目（Turbine）來(lái)提供把多個(gè)hystrix.stream的內(nèi)容聚合為一個(gè)數(shù)據(jù)源供Dashboard展示。

2.1 添加依賴(lài)

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，表明監(jiān)控哪些服務(wù)。
  • turbine.aggregator.clusterConfig：指定聚合哪些集群，多個(gè)使用”,”分割，默認(rèn)為default?？墒褂?/li>

http://.../turbine.stream?cluster={clusterConfig之一}訪問(wèn)。

  • turbine.clusterNameExpression ：

1、clusterNameExpression指定集群名稱(chēng)，默認(rèn)表達(dá)式appName；此時(shí)：

turbine.aggregator.clusterConfig需要配置想要監(jiān)控的應(yīng)用名稱(chēng)；

2、當(dāng)clusterNameExpression: default時(shí)，turbine.aggregator.clusterConfig可以不寫(xiě)，因?yàn)槟J(rèn)就是

default；

3、當(dāng)clusterNameExpression: metadata[‘cluster’]時(shí)，假設(shè)想要監(jiān)控的應(yīng)用配置了

eureka.instance.metadata-map.cluster: ABC，則需要配置，同時(shí)

turbine.aggregator.clusterConfig: ABC

2.3 啟動(dòng)類(lèi)

啟動(dòng)類(lèi)添加@EnableTurbine，激活對(duì)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 測(cè)試

在示例項(xiàng)目spring-cloud-consumer-hystrix基礎(chǔ)上修改為兩個(gè)服務(wù)的調(diào)用者spring-cloud-consumer-node1和

spring-cloud-consumer-node2。

spring-cloud-consumer-node1項(xiàng)目改動(dòng)如下：application.properties文件內(nèi)容

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

spring-cloud-consumer-node2項(xiàng)目改動(dòng)如下：application.properties文件內(nèi)容

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

HelloRemote類(lèi)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(name = "spring-cloud-producer", fallback = HelloRemoteHystrix.class)
public interface HelloRemote {
    @RequestMapping(value = "/hello")
    public String hello(@RequestParam(value = "name") String name);
}

對(duì)應(yīng)的HelloRemoteHystrix和ConsumerController類(lèi)跟隨修改，具體查看代碼

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);
    }
}

修改完畢后，依次啟動(dòng)spring-cloud-eureka、spring-cloud-consumer-node1、spring-cloud-consumer-

node2、spring-cloud-hystrix-dashboard-turbine

打開(kāi)eureka后臺(tái)可以看到注冊(cè)了三個(gè)服務(wù)：

在這里插入圖片描述

訪問(wèn) 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}

并且會(huì)不斷刷新以獲取實(shí)時(shí)的監(jiān)控?cái)?shù)據(jù)，說(shuō)明和單個(gè)的監(jiān)控類(lèi)似，返回監(jiān)控項(xiàng)目的信息。

進(jìn)行圖形化監(jiān)控查看，輸入：http://localhost:8001/hystrix，返回酷酷的小熊界面

在這里插入圖片描述

輸入：http://localhost:8001/turbine.stream，然后點(diǎn)擊 Monitor Stream ,可以看到出現(xiàn)了倆個(gè)監(jiān)控列表

在這里插入圖片描述

訪問(wèn)http://localhost:9001/hello/neo和http://localhost:9002/hello/neo

在這里插入圖片描述
