## Arthas( 阿尔萨斯) 能为你做什么?
![arthas](arthas.png)
`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:
0. 这个类从哪个 jar 包加载的?为什么会报各种类相关的 Exception?
0. 我改的代码为什么没有执行到?难道是我没 commit? 分支搞错了?
0. 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?
0. 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!
0. 是否有一个全局视角来查看系统的运行状况?
0. 有什么办法可以监控到JVM的实时运行状态?
`Arthas`支持JDK 6+,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。
