14Ribbon整合断路器监控Hystrix Dashboard

Posted 2021-02-21

上一篇只是大概介绍了一下断路器Hystrix Dashboard监控，如何使用Hystrix Dashboard监控微服务的状态呢？这篇看看Ribbon如何整合断路器监控Hystrix Dashboard。今天的项目主要整合sc-eureka-client-consumer-ribbon-hystrix项目和sc-hystrix-dashboard项目

1、新建项目sc-ribbon-hystrix-dashboard，对应的pom.xml文件

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

    <groupId>spring-cloud</groupId>
    <artifactId>sc-ribbon-hystrix-dashboard</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
    </parent>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

        </dependencies>
    </dependencyManagement>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

        <!-- <dependency> 
                <groupId>org.springframework.cloud</groupId> 
                <artifactId>spring-cloud-starter-ribbon</artifactId> 
                    <version>1.4.5.RELEASE</version> 
            </dependency> -->

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
        </dependency>

        <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--        
        <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-hystrix</artifactId>
                <version>1.4.5.RELEASE</version>
        </dependency> -->

        <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>

        <!-- <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
                <version>1.4.5.RELEASE</version>
        </dependency> -->

        <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

        <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

    </dependencies>
</project>

可以看到这个pom.xml文件是sc-eureka-client-consumer-ribbon-hstrix项目和sc-hystrix-dashboard项目的pom.xml的并集

2、新建spring boot 启动类HystrixDashboardApplication.java

package sc.consumer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

@SpringBootApplication
@EnableEurekaClient
@EnableHystrix
@EnableHystrixDashboard
public class HystrixDashboardApplication {

    public static void main(String[] args) {

        SpringApplication.run(HystrixDashboardApplication.class, args);

    }

}

可以看到这个启动类的注解也是sc-eureka-client-consumer-ribbon-hstrix项目和sc-hystrix-dashboard项目的启动类的并集

3、其他的java类就不多说了，项目接口如下

4、分别启动配置中心和sc-eureka-server和服务提供者sc-eureka-client-provider

5、启动项目sc-ribbon-hystrix-dashboard
方式一：http://127.0.0.1:5600/hystrix验证是否启动成功

方式二：访问http://127.0.0.1:5600/hystrix.stream

这个是访问DashboardServletConfig.java这个servlet对应的地址
上篇说了一下下图这段英文的大概意思

6、演示一下单应用模式下的断路器监控Hystrix Dashboard
在url里输入：http://127.0.0.1:5600/hystrix.stream（IP和端口对应服务消费者的IP和端口）

然后点击Monitor Stream按钮

7、使用postman访问任何接口，以获取用户列表为例（http://127.0.0.1:5600/cli/user/listUser），多访问几次在查看对应的监控界面

发现监控界面的图出现了动态变化，这个就是对服务调用的监控。图中相关单元的含义可以查看：
https://github.com/Netflix-Skunkworks/hystrix-dashboard/wiki

http://127.0.0.1:5600/hystrix.stream对应的界面也出现了大量数据，这个也是对服务调用监控的数据。

其他接口也自行测试。
