Spring Cloud 系列之 Netflix Hystrix 服务监控

3 月,跳不动了?>>> Actuator      Hystrix 除了可以实现服务容错之外,还提供了近乎实时的监控功能,将服务执行结果和运行指标,请求数量成功数量等等这些状态通过 Actuator 进行收集,然后访问 /actuator/hystrix.stream 即可看到实时的监控数据。    添加依赖      在需要开启数据监控的项目中添加 actuator 依赖。 <!-- spring boot actuator 依赖 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>    配置文件      在配置文件中开启 hystrix.stream 端点。如果希望所有端点暴露,配置为 '*' 。 # 度量指标监控与健康检查 management: endpoints: web: exposure: include: hystrix.stream    启动类    package com.example; import org.springframework.boot.SpringApplication; import org.springframework.boot

SpringCloud 基础教程(九)-Hystrix服务监控(下)

  我的博客: 程序员笑笑生 ,欢迎浏览博客!  上一章 SpringCloud基础教程(八)-Hystrix熔断器(上) 当中,我们介绍了Hystrix在分布式环境下,如何通过熔断、降级的方式解决了服务延迟或者故障出现的问题,本章我们将深入了解Hystrix的服务监控。 前言  当服务端因为网络延迟或故障出险问题时,我们可以通过Hystrix实现服务熔断,那么如何做到迅速的发现问题并且迅速的解决问题呢?熔断的监控工具有2款工具:Hystrix-dashboard和Turbine,Hystrix-dashboard是针对Hystrix进行实时的监控工具,通过Hystrix-dashboard我们可以直观的看到单个应用的服务信息。但是,在分布式的模式下,我们需要一个能够汇总所有的服务数据并直观的显示出来,这个工具就是Turbine。 一、健康检查  我们在 SpringCloud 基础教程(三)-Eureka 进阶 中提到了 Eureka是默认使用心跳机制来监测服务的健康与否的,我们通过在服务端引入actuator依赖,并修改yml配置,开启健康检查,能够查到服务是否正常,这里在需要被监测的服务组件中,开启监控也需要引入actuator: <dependency> <groupId>org.springframework.boot</groupId> <artifactId

InjectableFilterAttribute never hits the Filter

≡放荡痞女 提交于 2020-01-05 07:48:47
问题 On my base controller I have placed the Logger attribute. This LoggerAttribute looks like this: public class LoggerAttribute: InjectableFilterAttribute { public override Type FilterType { get { return typeof (LoggerActionFilter); } } } The ctor on this loggerattribute gets hit, but the FilterType getter not. The relevant part of the filter itself looks like this: public class LoggerActionFilter: IActionFilter { private readonly ILoggerService logger; public LoggerActionFilter (ILoggerService

Spring Boot with server.contextPath set vs. URL to hystrix.stream via Eureka Server

泄露秘密 提交于 2019-12-20 07:08:12
问题 I have Eureka Server with Turbine instance running and a few discovery clients that are connected to it. Everything works fine, but if I register a discovery client that has server.contextPath set, it didn't get recognized by InstanceMonitor and Turbine stream is not able to combine its hystrix.stream . This is how it looks in the logs of Eureka/Turbine server: 2015-02-12 06:56:23.265 INFO 1 --- [ Timer-0] c.n.t.discovery.InstanceObservable : Hosts up:3, hosts down: 0 2015-02-12 06:56:23.266

问题 I'm currently trying to find out why my InjectableAttributes never get to the filter part. Therefor I linked in the source project directly so I could easily put breakpoints etc. When I build however I get the following message: The following module was built either with optimizations enabled or without debug information: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\[a bunch of randomly named directories]\assembly\[more random names]\MvcTurbine.Web.DLL] To debug

Java运行状态分析2:获取线程状态及堆栈信息

谁说我不能喝 提交于 2019-12-12 05:27:51
问题 I have multiple service that are mapped thru zuul so my turbine project looks for hystrix.stream from the zuul project. I think i have setup everyting right because I can see the hits getting updated properly. But the below section for Thread Pools keeps on loading what am i missing here and whats the use of it, couldnot find anything that can help me to understand it actual use.Here is the screenshot of my dahsboard. Hystrix Dashboard Image Let me know if more info is needed for the same. 来源
