Hystrix DashBoard 監控儀表盤用來監測請求訪問量

1.監控系統配置

pom.xml

<!-- dashboard 客戶端 -->
 

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

application.yml

spring:
  application:
    name: hystrix-dashboard
server:
  port: 8010

Application.java

@EnableHystrixDashboard
@SpringBootApplication
public class HystrixDashboardApplication {

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

}

@EnableHystrixDashboard 開啟儀表盤功能

訪問: http://localhost:8010/hystrix

2.被監控服務配置

pom.xml

<!-- 系統健康監控工具 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

每個需要被監控的項目都要加,且是使用熔斷機制的項目

application.yml

spring:
  application:
    name: hystrix-client
    
server:
  port: 8091

feign:
  hystrix:
    enabled: true
    
management:
  endpoints:
    web:
      exposure:
        include: "*" # 暴露endpoints節點 2.x版本需要手動開啟

management.endpoints 管理端點, 2.x版本需要手動開啟

監控頁面輸入: http://localhost:8091/actuator/hystrix.stream

訪問被監聽的服務可以看到

或者被監控的項目采用如下配置

@Bean
public ServletRegistrationBean getServlet() {
 HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
 ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
 registrationBean.setLoadOnStartup(1);
 registrationBean.addUrlMappings("/hystrix.stream");
 registrationBean.setName("HystrixMetricsStreamServlet");
 return registrationBean;
}

監控頁面輸入: http://localhost:8091/hystrix.stream 進行監控

3.集群監控配置

創建spring-boot項目並添加依賴

pom.xml

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

application.xml

spring:
  application:
    name: turbine-client
    
server:
  port: 8020
  
turbine:
  app-config: hystrix-client
  aggregator:
    cluster-config: default
  cluster-name-expression: new String("default")
  combine-host-port: true

app-config 被監控集群的服務名稱

Application.java

@EnableTurbine
@SpringBootApplication
public class TurbineClientApplication {

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

}

監控頁面輸入: http://localhost:8020/turbine.stream
