Spring Cloud之服务监控turbine的示例

turbine是聚合服务器发送事件流数据的一个工具，hystrix的监控中，只能监控单个节点，实际生产中都为集群，因此可以通过turbine来监控集群下hystrix的metrics情况，通过eureka来发现hystrix服务。

新建turbine项目

TurbineApplication.java

package turbine;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;
/**
* Created by sai.luo on 2017/4/26.
*/
@SpringBootApplication
@EnableTurbine
@EnableHystrix
@EnableHystrixDashboard
public class TurbineApplication{
public static void main(String[] args) {
 SpringApplication.run(TurbineApplication.class,args);
}
}

application.yml

spring:
application:
name: turbine
server:
port: 8000
turbine:
app-config: hello,helloClient ##需要监控的服务名
aggregator:
clusterConfig: main ##需要监控的服务集群名
clusterNameExpression: metadata['cluster']

eureka:
instance:
preferIpAddress: true
statusPageUrlPath: /info.html
client:
serviceUrl:
 defaultZone: http://localhost:8761/eureka/

启动服务

helloserviceeureka 项目 appliation.yml 增加集群配置

更改为

spring:
application:
name: hello

server:
port: 9001

eureka:
instance:
lease-renewal-interval-in-seconds: 3
lease-expiration-duration-in-seconds: 5
metadata-map:
 cluster: main
client:
serviceUrl:
 defaultZone: http://localhost:8761/eureka/
registry-fetch-interval-seconds: 3

logging:
level:
com:
 netflix:
 eureka: OFF
 discovery: OFF

pom.xml增加hystrix依赖包

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

同理ribboneureka 项目 application.yml 增加集群配置

更改后如下

spring:
application:
name: helloClient

server:
port: 20000

eureka:
instance:
lease-renewal-interval-in-seconds: 3
lease-expiration-duration-in-seconds: 5
metadata-map:
 cluster: main
client:
serviceUrl:
 defaultZone: http://localhost:8761/eureka/
registry-fetch-interval-seconds: 3

logging:
level:
com:
 netflix:
 eureka: OFF
 discovery: OFF

pom.xml增加hystrix依赖包

RibbonEurekaApplication.java 增加注解

@EnableHystrix

启动项目

访问 localhost:8000/hystrixx 可以看到页面

注： turbine只能监控hystrix服务，不是hystrix服务，不能监控，如 hello这个服务虽然配置了集群，但是没有使用hystrix,所以不会受监控。
