`Arthas` 是Alibaba开源的Java诊断工具，深受开发者喜爱。

当你遇到以下类似问题而束手无策时，`Arthas`可以帮助你解决：

1.  这个类从哪个 jar 包加载的？为什么会报各种类相关的 Exception？
2.  我改的代码为什么没有执行到？难道是我没 commit？分支搞错了？
3.  遇到问题无法在线上 debug，难道只能通过加日志再重新发布吗？
4.  线上遇到某个用户的数据处理有问题，但线上同样无法 debug，线下无法重现！
5.  是否有一个全局视角来查看系统的运行状况？
6.  有什么办法可以监控到JVM的实时运行状态？
7.  怎么快速定位应用的热点，生成火焰图？

`Arthas`支持JDK 6+，支持Linux/Mac/Winodws，采用命令行交互模式，同时提供丰富的 `Tab` 自动补全功能，进一步方便进行问题的定位和诊断。
