springcloud实战之9 断路器-集群监控（turbine）

- 日理万妓 2022-06-03 06:48 207阅读 0赞

上一篇介绍了单例的服务监控，本章介绍对集群的监控。通过引入turbine，通过它来汇集监控信息，并将聚合后的信息提供给Hystrix Dashboard来集中展示和监控。

其工作架构图如下：

## 构建springcloud-hystrix-turbine项目 ##

### 引入依赖 ###

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
        <relativePath />
    </parent>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-turbine</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>

### 创建运行入口 ###

@SpringBootApplication
    @EnableDiscoveryClient
    @EnableTurbine
    public class SpringCloudHystrixTurbineApplication { 
        public static void main(String[] args) {
            new SpringApplicationBuilder(SpringCloudHystrixTurbineApplication.class).web(true).run(args);
        }
    }

EnableDiscoveryClient声明是eureka client

EnableTurbine申明启用集群监控

### 创建配置文件 ###

server:
      port: 8006
    management:
      port: 8007
    spring:
      application:
        name: springcloud-hystrix-turbine
    
    eureka:
      client:
        service-url:
          defaultZone: http://peer1:8080/eureka/
      instance:
        lease-renewal-interval-in-seconds: 30
        lease-expiration-duration-in-seconds: 90
    turbine:
      app-config: springcloud-hystrix-dashboard # 指定了需要收集监控信息的服务名
      cluster-name-expression: new String('default')  # 指定集群名称
      combine-host-port: true # 设置为true，可以让同一主机上的服务通过主机名与端口号的组合来进行区分，

## 启动项目 ##

1.启动服务注册中心集群（springcloud-server-eureka）

2.启动服务提供者（springcloud-producer-rest）

3.启动服务消费者（springcloud-hystirx-dashboard）

4.启动服务集群监控者（springcloud-hystrix-turbine）

启动后的注册服务图如下

![这里写图片描述][SouthEast 1]

1.打开监控页面：[http://localhost:8005/hystrix][http_localhost_8005_hystrix],如下图

![这里写图片描述][SouthEast 2]

2.再长框中输入集群监控地址：[http://localhost:8006/turbine.stream][http_localhost_8006_turbine.stream]，如下图

![这里写图片描述][SouthEast 3]

3.调用服务接口地址：[http://localhost:8005/api/rest/home][http_localhost_8005_api_rest_home]，即可实现监控，如下图
