Spring Cloud-hystrix Dashboard(八)

 

单机模式

1.创建一个dashboard项目

2.引入依赖

<!--histrix依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <!--dashboard依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
        <!--端点依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

3.在主类上打上注解@EnableHystrixDashboard开启dashboard

@SpringBootApplication
@EnableHystrixDashboard
public class SpringCloudDashboardApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudDashboardApplication.class, args);
    }

}

4.配置文件配置应用名字和端口

spring:
  application:
    name: hystrix-dashboard
server:
  port: 2001

5.启动访问http://127.0.0.1:2001/hystrix

6.在consumer增加hystirx端点的Servlet

/**
 * 用于开启histrix 端点 用于dashboard图形化
 */
@Configuration
public class HystrixStreamServletConfig {
    @Bean
    public ServletRegistrationBean getServlet() {
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);

        registrationBean.setLoadOnStartup(1);

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

        registrationBean.setName("HystrixMetricsStreamServlet");


        return registrationBean;

    }
}

7.访问http://127.0.0.1:9001/actuator/hystrix.stream  出现以下内容表示成功 将连接粘贴到仪表盘 开启分析

8.将连接粘贴到仪表盘 开启监控和分析

9.访问一个hystrix请求将会出现监控页面

Turbine集群模式

1.创建一个Turbine项目

2.添加依赖

<!--&lt;!&ndash;实现hystrix集群监控依赖&ndash;&gt;-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>

3.开启turbine自动化配置和注册中心服务发现的功能 turbine里面依赖eurekaClient

SpringBootApplication
@EnableTurbine//启用turbine
@EnableDiscoveryClient //开启服务发现
public class SpringCloudTurbineApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudTurbineApplication.class, args);
    }

}

4.配置文件配置

spring:
  application:
    name: trubine #http://localhost:9090/turbine.stream
server:
  port: 9090
eureka:
  client:
    serviceUrl:
      defaultZone: http://peer1:1111/eureka,http://localhost:peer2/eureka
turbine:
  app-config: consumer #监控的服务名 多个,号隔开
  cluster-name-expression: new String('default') #指定集群的名称为default 当服务非常多turbine可以启动多个turbine构建集群 具体书194页
  combine-host-port: true #可以通过主机名和端口名组合来进行区分

5.打包2个consumer并启动

 

6.在hystirx仪表盘配置监听trubine连接http://localhost:9090/turbine.stream
