## Hystrix断路器的状态监控 ##

> Spring Boot Actuator提供了很多监控端点。在Spring boot应用中，要实现可监控的功能，依赖的是 `spring-boot-starter-actuator` 这个组件。它提供了很多监控和管理你的spring boot应用的HTTP或者JMX端点，并且你可以有选择地开启和关闭部分功能。当你的spring boot应用中引入下面的依赖之后，将自动的拥有审计、健康检查、Metrics监控功能。

具体的使用方法:首先在pom.xml中加入依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

Spring Boot2.x之后配置方式和之前有所改变。以前是通过 http://\{ip\}:\{port\}/hystrix.stream进行访问 SpringBoot2.x之后可使用`http://{ip}:{port}/base-path/{endpoint}`的形式访问这些端点，从而了解应用程序的运行状况。这里的base-path默认是/actuator。我们可以从源码中看到。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nja2V2aW5jeWg_size_16_color_FFFFFF_t_70]

当然我们也可以通过如下的配置修改 base-path

management:
      endpoints:
        web:
          base-path: "/monitor"

## Endpoints ##

> actuator 的核心部分，它用来监视应用程序及交互，spring-boot-actuator中已经内置了非常多的 Endpoints（health、info、beans、httptrace、shutdown等等），同时也允许我们自己扩展自己的端点

> Spring Boot 2.0 中的端点和之前的版本有较大不同,使用时需注意。另外端点的监控机制也有很大不同，启用了不代表可以直接访问，还需要将其暴露出来，传统的management.security管理已被标记为不推荐。

> 我们需要加入配置将端点暴露出来。通过下面的配置启用所有的监控端点，默认情况下，这些端点是禁用的；

management:
      endpoints:
        web:
          exposure:
            include: "*"

"\*"号代表启用所有的监控端点，可以单独启用，例如，health，info，metrics等。

现在通过actuator/+端点名就可以获取相应的信息。

如果我们不加上上面暴露全部的监控端点，我们启动项目之后访问http://localhost:8762/actuator(项目地址+/actuator)，只能看到如下暴露的端点：

{ 
        "_links": { 
            "self": { 
                "href": "http://localhost:8762/actuator",
                "templated": false
            },
            "health": { 
                "href": "http://localhost:8762/actuator/health",
                "templated": false
            },
            "health-component-instance": { 
                "href": "http://localhost:8762/actuator/health/{component}/{instance}",
                "templated": true
            },
            "health-component": { 
                "href": "http://localhost:8762/actuator/health/{component}",
                "templated": true
            },
            "info": { 
                "href": "http://localhost:8762/actuator/info",
                "templated": false
            }
        }
    }

默认只开放了info、health两个端点，剩余的需要自己通过配置`management.endpoints.web.exposure.include`属性来加载。

当我们加上配置之后，访问http://localhost:8762/actuator(项目地址+/actuator)，就可以看到暴露出来更多的端点：

{ 
        "_links": { 
            "self": { 
                "href": "http://localhost:8762/actuator",

            "health": {

        }
    }

## 内置Endpoints ##

我这里只是简单列了一些内置Endpoints，更详细的可以参考下：  
[Spring Boot 参考指南（端点）][Spring Boot]

<table> 
 <thead> 
  <tr> 
   <th>端点</th> 
   <th align="left">描述</th>

  <tr> 
   <td>threaddump</td> 
   <td align="left">执行一个线程dump</td> 
   <td align="left">GET</td> 
  </tr> 
 </tbody> 
</table>

## 健康检查 ##

当我们开启health的健康端点时，我们能够查到应用健康信息是一个汇总的信息，访问http://localhost:8762/actuator/health 时，我们获取到的信息是\{“status”:“UP”\}，status的值还有可能是 DOWN。  
要想查看详细的应用健康信息需要配置management.endpoint.health.show-details 的值为always.

> management.endpoint.health.show-details的值除了always之外还有when-authorized、never，默认值是never。

management:
      endpoints:
        web:
          exposure:
            include: "*"
      endpoint:
        health:
          show-details: always

配置之后我们再次访问http://localhost:8762/actuator/health，获取的信息如下：

{ 
        "status": "UP",
        "details": { 
            "diskSpace": { 
                "status": "UP",
                "details": { 
                    "total": 126712016896,
                    "free": 35607068672,
                    "threshold": 10485760
                }
            },
            "refreshScope": { 
                "status": "UP"
            },
            "discoveryComposite": { 
                "status": "UP",
                "details": { 
                    "discoveryClient": { 
                        "status": "UP",
                        "details": { 
                            "services": [
                                "cloud-service-member",
                                "cloud-service-order"
                            ]
                        }
                    },
                    "eureka": { 
                        "description": "Remote status from Eureka server",
                        "status": "UP",
                        "details": { 
                            "applications": { 
                                "CLOUD-SERVICE-MEMBER": 1,
                                "CLOUD-SERVICE-ORDER": 1
                            }
                        }
                    }
                }
            },
            "hystrix": { 
                "status": "UP"
            }
        }
    }

然后我们可以看到hystrix的status

"hystrix": { 
        "status": "UP"
    }

> 这里值得注意的是，如果我们发现我们的代码执行了fallback，但此时Hystrix的状态依然是UP，这是因为我们的失败率还没有达到阈值（默认是5秒内20次失败）。执行回退逻辑并不代表断路器已经打开。请求失败、超时、被拒绝以及断路器打开时等都会执行回退逻辑。

## Hystrix的监控 ##

当我们添加了`spring-boot-starter-actuator`依赖之后，就可使用/hystrix.stream端点获得Hystrix的监控信息了。

我们只需要在我们的启动类中加上@EnableCircuitBreaker或@EnableHystrix

并且添加如下依赖:

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

然后我们启动项目，访问http://localhost:8765/actuator/hystrix.stream还有http://localhost:8762/actuator/hystrix.stream

然后我们发现内容都是ping

ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping: 
    
    ping:

我们只需要访问一下我们的服务即可，访问http://localhost:8762/member/orders还有http://localhost:8765/order/members，然后我们继续访问http://localhost:8765/actuator/hystrix.stream还有http://localhost:8762/actuator/hystrix.stream，就可以看到不停重复如下内容:

ping: 
    
    data: { "type":"HystrixCommand","name":"OrderFeign#getAllOrderList()","group":"cloud-service-order","currentTime":1568819810783,"isCircuitBreakerOpen":false,"errorPercentage":0,"errorCount":0,"requestCount":0,"rollingCountBadRequests":0,"rollingCountCollapsedRequests":0,"rollingCountEmit":0,"rollingCountExceptionsThrown":0,"rollingCountFailure":0,"rollingCountFallbackEmit":0,"rollingCountFallbackFailure":0,"rollingCountFallbackMissing":0,"rollingCountFallbackRejection":0,"rollingCountFallbackSuccess":0,"rollingCountResponsesFromCache":0,"rollingCountSemaphoreRejected":0,"rollingCountShortCircuited":0,"rollingCountSuccess":0,"rollingCountThreadPoolRejected":0,"rollingCountTimeout":0,"currentConcurrentExecutionCount":0,"rollingMaxConcurrentExecutionCount":0,"latencyExecute_mean":0,"latencyExecute":{ "0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0},"latencyTotal_mean":0,"latencyTotal":{ "0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0},"propertyValue_circuitBreakerRequestVolumeThreshold":20,"propertyValue_circuitBreakerSleepWindowInMilliseconds":5000,"propertyValue_circuitBreakerErrorThresholdPercentage":50,"propertyValue_circuitBreakerForceOpen":false,"propertyValue_circuitBreakerForceClosed":false,"propertyValue_circuitBreakerEnabled":true,"propertyValue_executionIsolationStrategy":"THREAD","propertyValue_executionIsolationThreadTimeoutInMilliseconds":1000,"propertyValue_executionTimeoutInMilliseconds":1000,"propertyValue_executionIsolationThreadInterruptOnTimeout":true,"propertyValue_executionIsolationThreadPoolKeyOverride":null,"propertyValue_executionIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_fallbackIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"propertyValue_requestCacheEnabled":true,"propertyValue_requestLogEnabled":true,"reportingHosts":1,"threadPool":"cloud-service-order"}
    
    data: { "type":"HystrixThreadPool","name":"cloud-service-order","currentTime":1568819810783,"currentActiveCount":0,"currentCompletedTaskCount":1,"currentCorePoolSize":10,"currentLargestPoolSize":1,"currentMaximumPoolSize":10,"currentPoolSize":1,"currentQueueSize":0,"currentTaskCount":1,"rollingCountThreadsExecuted":0,"rollingMaxActiveThreads":0,"rollingCountCommandRejections":0,"propertyValue_queueSizeRejectionThreshold":5,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"reportingHosts":1}

data: { "type":"HystrixCommand","name":"MemberFeign#getAllMemberList()","group":"cloud-service-member","currentTime":1568819800314,"isCircuitBreakerOpen":false,"errorPercentage":0,"errorCount":0,"requestCount":0,"rollingCountBadRequests":0,"rollingCountCollapsedRequests":0,"rollingCountEmit":0,"rollingCountExceptionsThrown":0,"rollingCountFailure":0,"rollingCountFallbackEmit":0,"rollingCountFallbackFailure":0,"rollingCountFallbackMissing":0,"rollingCountFallbackRejection":0,"rollingCountFallbackSuccess":0,"rollingCountResponsesFromCache":0,"rollingCountSemaphoreRejected":0,"rollingCountShortCircuited":0,"rollingCountSuccess":0,"rollingCountThreadPoolRejected":0,"rollingCountTimeout":0,"currentConcurrentExecutionCount":0,"rollingMaxConcurrentExecutionCount":0,"latencyExecute_mean":0,"latencyExecute":{ "0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0},"latencyTotal_mean":0,"latencyTotal":{ "0":0,"25":0,"50":0,"75":0,"90":0,"95":0,"99":0,"99.5":0,"100":0},"propertyValue_circuitBreakerRequestVolumeThreshold":20,"propertyValue_circuitBreakerSleepWindowInMilliseconds":5000,"propertyValue_circuitBreakerErrorThresholdPercentage":50,"propertyValue_circuitBreakerForceOpen":false,"propertyValue_circuitBreakerForceClosed":false,"propertyValue_circuitBreakerEnabled":true,"propertyValue_executionIsolationStrategy":"THREAD","propertyValue_executionIsolationThreadTimeoutInMilliseconds":1000,"propertyValue_executionTimeoutInMilliseconds":1000,"propertyValue_executionIsolationThreadInterruptOnTimeout":true,"propertyValue_executionIsolationThreadPoolKeyOverride":null,"propertyValue_executionIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_fallbackIsolationSemaphoreMaxConcurrentRequests":10,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"propertyValue_requestCacheEnabled":true,"propertyValue_requestLogEnabled":true,"reportingHosts":1,"threadPool":"cloud-service-member"}
    
    data: { "type":"HystrixThreadPool","name":"cloud-service-member","currentTime":1568819800314,"currentActiveCount":0,"currentCompletedTaskCount":1,"currentCorePoolSize":10,"currentLargestPoolSize":1,"currentMaximumPoolSize":10,"currentPoolSize":1,"currentQueueSize":0,"currentTaskCount":1,"rollingCountThreadsExecuted":0,"rollingMaxActiveThreads":0,"rollingCountCommandRejections":0,"propertyValue_queueSizeRejectionThreshold":5,"propertyValue_metricsRollingStatisticalWindowInMilliseconds":10000,"reportingHosts":1}

这是因为系统会不断地刷新以获得实时的监控数据。Hystrix的监控指标非常全面，例如HystrixCommand的名称、group名称、断路器状态、错误率、错误数等。

## 使用Hystrix Dashboard可视化监控数据 ##

> 前面讨论了Hystrix的监控，但访问/hystrix.stream端点获得的数据是以文字形式展示的。  
> 很难通过这些数据，一眼看出系统当前的运行状态。  
> 可使用Hystrix Dashboard，从让监控数据图形化、可视化。

我们新建一个module，命名为cloud-hystrix-dashboard

然后我们加入hystrix-dashboard的pom依赖:

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

> spring cloud 2.x之后spring-cloud-starter-hystrix-dashboard和spring-cloud-starter-hystrix都标志为过期。参考:[13、如何使用断路器监控Hystrix Dashboard][13_Hystrix Dashboard]

推荐使用`<artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>`

然后加上application.yml的配置

server:
      port: 8766
    spring:
      application:
        name: cloud-hystrix-dashboard

最后是启动类上加上@EnableHystrixDashboard注解

package com.cc.cloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
    
    @SpringBootApplication
    @EnableHystrixDashboard
    public class HystrixDashboard { 
    
        public static void main(String[] args) { 
            SpringApplication.run(HystrixDashboard.class, args);
        }
    }

最后启动项目之后访问http://localhost:8766/hystrix即可看到如下画面:
