hystrixDashboard服務(wù)監(jiān)控

除了隔離依賴(lài)服務(wù)的調(diào)用以外，Hystrix還提供了準(zhǔn)實(shí)時(shí)的調(diào)用監(jiān)控（HystrixDashboard），Hystrix會(huì)持續(xù)地記錄所有通過(guò)Hystrix發(fā)起的請(qǐng)求的執(zhí)行信息，并以統(tǒng)計(jì)報(bào)表和圖形的形式展示給用戶(hù)，包括每秒執(zhí)行多少請(qǐng)求多少成功，多少失敗等。Netflix通過(guò)hystrix-metrics-event-stream項(xiàng)目實(shí)現(xiàn)了對(duì)以上指標(biāo)的監(jiān)控。SpringCloud也提供了HystrixDashboard的整合，對(duì)監(jiān)控內(nèi)容轉(zhuǎn)化成可視化界面。

1、新建cloud-consumer-hystrix-dashboard9001儀表盤(pán)監(jiān)控模塊

2、修改pom.xml文件引入儀表盤(pán)依賴(lài)

核心依賴(lài)：spring-cloud-starter-netflix-hystrix-dashboard

注意：所有的圖形化展示，都需要引入spring-boot-starter-actuator依賴(lài)，在8001、8002上都需要引入

3、添加YAML配置文件

server:

port:9001

4、建立啟動(dòng)類(lèi)

必須要加上@EnableHystrixDashboard注解激活

packagecom.zcl.springcloud;

importorg.springframework.boot.SpringApplication;

importorg.springframework.boot.autoconfigure.SpringBootApplication;

importflix.hystrix.dashboard.EnableHystrixDashboard;

*描述：儀表盤(pán)啟動(dòng)類(lèi)

@SpringBootApplication

@EnableHystrixDashboard

publicclassHystrixDashboardMain9001{

publicstaticvoidmain(String[]args){

SpringApplication.run(HystrixDashboardMain9001.class,args);

}

5、啟動(dòng)項(xiàng)目

啟動(dòng)項(xiàng)目測(cè)試：http://localhost:901/hystrix

使用方法：在下面頁(yè)面中輸入需要進(jìn)行監(jiān)控的地址即可

斷路器演示監(jiān)控

監(jiān)控8001注意事項(xiàng)

1、必須要有如下的兩個(gè)依賴(lài)

!--web--

dependency

groupIdorg.springframework.boot/groupId

artifactIdspring-boot-starter-web/artifactId

/dependency

dependency

groupIdorg.springframework.boot/groupId

artifactIdspring-boot-starter-actuator/artifactId

/dependency

2、對(duì)啟動(dòng)類(lèi)的修改

注意:新版本Hystrix需要在主啟動(dòng)類(lèi)MainAppHystrix8001中指定監(jiān)控路徑,否則會(huì)出現(xiàn)報(bào)錯(cuò)

packagecom.zcl.springcloud;

importflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;

importorg.springframework.boot.SpringApplication;

importorg.springframework.boot.autoconfigure.SpringBootApplication;

importorg.springframework.boot.web.servlet.ServletRegistrationBean;

importorg.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;

importflix.eureka.EnableEurekaClient;

importorg.springframework.context.annotation.Bean;

*描述：熔斷限流啟動(dòng)類(lèi)

@SpringBootApplication

@EnableEurekaClient

@EnableCircuitBreaker

publicclassPaymentHystrixMain8001{

publicstaticvoidmain(String[]args){

SpringApplication.run(PaymentHystrixMain8001.class,args);

*此配置是為了服務(wù)監(jiān)控而配置，與服務(wù)容錯(cuò)本身無(wú)關(guān)，springcloud升級(jí)后的坑

*ServletRegistrationBean因?yàn)閟pringboot的默認(rèn)路徑不是"/hystrix.stream"，

*只要在自己的項(xiàng)目里配置上下面的servlet就可以了

@Bean

publicServletRegistrationBeangetServlet(){

HystrixMetricsStreamServletstreamServlet=newHystrixMetricsStreamServlet();

ServletRegistrationBeanregistrationBean=newServletRegistrationBean(streamServlet);

registrationBean.setLoadOnStartup(1);

registrationBean.addUrlMappings("/hystrix.stream");

registrationBean.setName("HystrixMetricsStreamServlet");

returnregistrationBean;

}
