14、Ribbon整合断路器监控Hystrix Dashboard
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>finchley.release</version>
<type>pom</type>

</dependency>
</dependencies>
</dependencymanagement>
<properties>

</properties>
<dependencies>
<dependency>

<artifactid>spring-cloud-starter-netflix-eureka-client</artifactid>
</dependency>
<!-- <dependency>

</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:验证是否启动成功
方式二:访问
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:(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
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。
