Spring Cloud Hystrix Dashboard：断路器执行监控

Spring Cloud Hystrix Dashboard：断路器执行监控

摘要

Spring Cloud 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 。

Hystrix Dashboard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

创建一个hystrix-dashboard模块

启动相关服务

这次我们需要启动如下服务：eureka-server、demo-service、hystrix-service、hystrix-dashboard

 

Hystrix实例监控演示

 

 

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。

​

 

 

在启动类上添加@EnableTurbine来启用Turbine相关功能

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

 

Hystrix集群监控演示

  • 访问Hystrix Dashboard： http://192.16.10.208:38501/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：
