## 摘要 ##

Hystrix Dashboard 是Spring Cloud中查看Hystrix实例执行情况的一种仪表盘组件，支持查看单个实例和查看集群实例，本文将对其用法进行详细介绍。

## 简介 ##

Hystrix提供了Hystrix Dashboard来实时监控HystrixCommand方法的执行情况。 Hystrix Dashboard可以有效地反映出每个Hystrix实例的运行情况，帮助我们快速发现系统中的问题，从而采取对应措施。

## Hystrix 单个实例监控 ##

> 我们先通过使用Hystrix Dashboard监控单个Hystrix实例来了解下它的使用方法。

### 创建一个hystrix-dashboard模块 ###

> 用来监控hystrix实例的执行情况。

在pom.xml中添加相关依赖：

<dependency>
    	<groupId>org.springframework.cloud</groupId>
    	<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </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>

在application.yml进行配置：

server:
      port: 8501
    
    spring:
      application:
        name: hystrix-dashboard
    
    eureka:
      client:
        register-with-eureka: true
        fetch-registry: true
        service-url:
          defaultZone: http://localhost:8001/eureka/

在启动类上添加@EnableHystrixDashboard来启用监控功能：

@EnableHystrixDashboard
    @EnableDiscoveryClient
    @SpringBootApplication
    public class HystrixDashboardApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(HystrixDashboardApplication.class, args);
        }
    
    }

### 启动相关服务 ###

> 这次我们需要启动如下服务：eureka-server、user-service、hystrix-service、hystrix-dashboard，启动后注册中心显示如下。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70]

### Hystrix实例监控演示 ###

访问Hystrix Dashboard：[http://localhost:8501/hystrix][http_localhost_8501_hystrix]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 1]

填写好信息后点击监控按钮，这里我们需要注意的是，由于我们本地不支持https，所以我们的地址需要填入的是http，否则会无法获取监控信息；

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 2]

还有一点值得注意的是，被监控的hystrix-service服务需要开启Actuator的hystrix.stream端点，配置信息如下：

management:
      endpoints:
        web:
          exposure:
            #暴露hystrix监控端点
            include: 'hystrix.stream'

调用几次hystrix-service的接口：[http://localhost:8401/user/testCommand/1][http_localhost_8401_user_testCommand_1]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 3]

可以发现曾经我们在@HystrixCommand中添加的commandKey和threadPoolKey属性都显示在上面了，并且有4次调用都成功了。

### Hystrix Dashboard 图表解读 ###

> 图表解读如下，需要注意的是，小球代表该实例健康状态及流量情况，颜色越显眼，表示实例越不健康，小球越大，表示实例流量越大。曲线表示Hystrix实例的实时流量变化。

## Hystrix 集群实例监控 ##

> 这里我们使用Turbine来聚合hystrix-service服务的监控信息，然后我们的hystrix-dashboard服务就可以从Turbine获取聚合好的监控信息展示给我们了。

### 创建一个turbine-service模块 ###

> 用来聚合hystrix-service的监控信息。

在pom.xml中添加相关依赖：

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
    	<groupId>org.springframework.cloud</groupId>
    	<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
    <dependency>
    	<groupId>org.springframework.cloud</groupId>
    	<artifactId>spring-cloud-starter-netflix-turbine</artifactId>
    </dependency>

在application.yml进行配置，主要是添加了Turbine相关配置：

server:
      port: 8601
    
    spring:
      application:
        name: turbine-service
    
    eureka:
      client:
        register-with-eureka: true
        fetch-registry: true
        service-url:
          defaultZone: http://localhost:8001/eureka/
    
    turbine:
      # 指定需要收集信息的服务名称
      app-config: hystrix-service
      # 指定服务所属集群
      cluster-name-expression: new String('default')
      # 以主机名和端口号区分服务
      combine-host-port: true

在启动类上添加@EnableTurbine来启用Turbine相关功能：

@EnableTurbine
    @EnableDiscoveryClient
    @SpringBootApplication
    public class TurbineServiceApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(TurbineServiceApplication.class, args);
        }
    
    }

### 启动相关服务 ###

> 使用application-replica1.yml配置再启动一个hystrix-service服务，启动turbine-service服务，此时注册中心显示如下。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 5]

### Hystrix集群监控演示 ###

访问Hystrix Dashboard：[http://localhost:8501/hystrix][http_localhost_8501_hystrix]

添加集群监控地址，需要注意的是我们需要添加的是turbine-service的监控端点地址：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 6]

调用几次hystrix-service的接口：[http://localhost:8401/user/testCommand/1][http_localhost_8401_user_testCommand_1]以及[http://localhost:8402/user/testCommand/1][http_localhost_8402_user_testCommand_1]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly90aGlua3dvbi5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70 7]

可以看到我们的Hystrix实例数量变成了两个。
