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

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 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); } }

pom.xml

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 <?xml version="1.0" encoding="utf-8"?> <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> <artifactid>turbine</artifactid> <properties> <project.build.sourceencoding>utf-8</project.build.sourceencoding> <java.version>1.8</java.version> </properties> <parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.5.2.release</version> <relativepath/> <!-- lookup parent from repository --> </parent> <dependencies> <!-- hystrix依赖 --> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-hystrix</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-hystrix-dashboard</artifactid> </dependency> <!-- turnbine依赖 --> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-turbine</artifactid> </dependency> </dependencies> <dependencymanagement> <dependencies> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-dependencies</artifactid> <version>camden.sr5</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencymanagement> <build> <plugins> <plugin> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-maven-plugin</artifactid> </plugin> </plugins> </build> </project>

application.yml

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 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

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 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

? 1 2 3 4 <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

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 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

? 1 @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。
