springcloud turbine叢集監控

1. 建立項目 turbineDashboard, pom.xml依賴

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
</dependency>
 <!--turbine叢集監控-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-turbine</artifactId>
</dependency>
           

2.application.properties

server.port=8080
spring.application.type=turbine
spring.application.group=group
spring.application.name=${spring.application.group}-${spring.application.type}
dashboard.register.host=http://
eureka.client.service-url.defaultZone=${dashboard.register.host}/eureka
eureka.instance.lease-renewal-interval-in-seconds=10
eureka.instance.lease-expiration-duration-in-seconds=30
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.cloud.client.ipAddress}:${server.port}
eureka.client.eureka-server-read-timeout-seconds=60


#GROUP-ORDER和TEST-TURBINE 為其它服務的spring.application.name, 部署多個相同name的服務形成一個叢集
turbine.aggregator.clusterConfig=GROUP-ORDER,TEST-TURBINE
#服務名,此處與叢集名相同
turbine.appConfig=GROUP-ORDER,TEST-TURBINE
#new String("default"): 将多個叢集在同一個stream中展示
#metadata['cluster']  : 将多個叢集在各自的stream中展示, 
turbine.clusterNameExpression=metadata['cluster']
           

3.在要監控的服務[GROUP-ORDER,TEST-TURBINE]增加以下配置

eureka.instance.metadata-map.cluster=TEST-TURBINE
           

4. 啟動入口配置

@EnableEurekaClient
@SpringBootApplication
@EnableHystrix
@EnableHystrixDashboard
@EnableTurbine
public class TurbineApplication {

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

4. 啟動後通路http://localhost:8080/hystrix, 監控cluster為TEST-TURBINE的叢集
