前几篇已经实现了对单个服务实例的监控,当然在实际应用中,单个实例的监控数据没有多大的价值,我们其实更需要的是一个集群系统的监控信息,这时就需要引入Turbine。Turbine能够汇集监控信息,并将聚合后的信息提供给Hystrix Dashboard来集中展示和监控。
本文将结合之前学习的注册中心Eureka、服务提供者Provider、断路器Hystrix和仪表盘Dashboard,学习断路器集群监控Turbine,最终整体架构如下:
项目说明:
注册中心:sc-eureka-server
服务提供者:sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2
服务消费者、断路器:sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2
集群监控、仪表盘:sc-client-turbine-hystrix
1、注册中心项目sc-eureka-server参考《eureka注册中心单机》
2、服务提供者项目sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2由项目sc-eureka-client-provider改造而来。
sc-server-turbine-hystrix-dashboard-node1:
sc-server-turbine-hystrix-dashboard-node2:
3、服务消费者、断路器项目sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2由项目sc-feign-hystrix-dashboard改造而来。
sc-client-turbine-hystrix-dashboard-node1
(1)bootstrap.yml修改
server:
port: 5801
(2)application.yml文件修改
(3)去掉springcloud启动类的EnableHystrixDashboard注解
sc-client-turbine-hystrix-dashboard-node2
(1)bootstrap.yml修改
server:
port: 5802
(2)application.yml文件修改
(3)去掉springcloud启动类的EnableHystrixDashboard注解
注: turbine只能监控Hystrix服务。不是Hystrix的服务不能监控。所以配置文件都配置了如下配置项
4、新建集群监控、仪表盘项目sc-client-turbine-hystrix,对应的pom.xml文件如下
<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> <groupId>spring-cloud</groupId> <artifactId>sc-client-turbine-hystrix</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>sc-client-turbine-hystrix</name> <url>http://maven.apache.org</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.4.RELEASE</version> </parent> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <!-- <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-turbine</artifactId> <version>1.4.5.RELEASE</version> </dependency> --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-turbine</artifactId> </dependency> <!-- <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId> <version>1.4.5.RELEASE</version> </dependency> --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
5、新建配置文件application.yml
spring: application: name: sc-client-turbine-hystrix eureka: client: registerWithEureka: true #是否将自己注册到Eureka服务中,默认为true fetchRegistry: true #是否从Eureka中获取注册信息,默认为true serviceUrl: defaultZone: http://localhost:5001/eureka/ server: port: 9091 turbine: appConfig: sc-client-turbine-hystrix-dashboard-node1,sc-client-turbine-hystrix-dashboard-node2 # 配置Eureka中的serviceId列表,表明监控哪些服务 clusterNameExpression: new String("default") # 1. clusterNameExpression指定集群名称,默认表达式appName;此时:turbine.aggregator.clusterConfig需要配置想要监控的应用名称 # 2. 当clusterNameExpression: default时,turbine.aggregator.clusterConfig可以不写,因为默认就是default # 3. 当clusterNameExpression: metadata['cluster']时,假设想要监控的应用配置了eureka.instance.metadata-map.cluster: ABC,则需要配置,同时turbine.aggregator.clusterConfig: ABC instanceUrlSuffix: /hystrix.stream aggregator: clusterConfig: default # 指定聚合哪些集群,多个使用","分割,默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问
6、新建springboot启动类
package sc.client.turbine; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard; import org.springframework.cloud.netflix.turbine.EnableTurbine; @SpringBootApplication @EnableHystrixDashboard @EnableTurbine @EnableEurekaClient public class TurbineApplication { public static void main(String[] args) { SpringApplication.run(TurbineApplication.class, args); } }
7、按照如下先后顺序启动项目
(1)sc-eureka-server
(2)sc-server-turbine-hystrix-dashboard-node1、sc-server-turbine-hystrix-dashboard-node2
(3)sc-client-turbine-hystrix-dashboard-node1、sc-client-turbine-hystrix-dashboard-node2
(4)sc-client-turbine-hystrix
8、访问注册中心 http://127.0.0.1 :5001/确认服务都启动成功
9、验证Turbine集群监控
访问 http://localhost :9091/turbine.stream,返回如下数据
并且会不断刷新以获取实时的监控数据,说明与单个的监控类似,返回监控项目的信息。进行图形化监控查看,输入 http://localhost :9091/hystrix,返回如下界面
输入 http://localhost :9091/turbine.stream,然后点击 Monitor Stream ,可以看到出现如下界面
没有出现任何监控图表。分别访问 http://127.0.0.1 :5801/feign/user/getUser/1和 http://127.0.0.1 :5802/feign/user/listUser(尽量多访问几次)
返回查看Turbine集群监控图表界面
