简介
Arthas 是一款线上监控诊断产品，通过全局视角实时查看应用 load、内存、gc、线程的状态信息，并能在不修改应用代码的情况下，对业务问题进行诊断，包括查看方法调用的出入参、异常，监测方法执行耗时，类加载信息等，大大提升线上问题排查效率。
Arthas（阿尔萨斯）能为你做什么？
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：
- 这个类从哪个 jar 包加载的？为什么会报各种类相关的 Exception？
- 我改的代码为什么没有执行到？难道是我没 commit？分支搞错了？
- 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？
- 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！
- 是否有一个全局视角来查看系统的运行状况？
- 有什么办法可以监控到 JVM 的实时运行状态？
- 怎么快速定位应用的热点，生成火焰图？
- 怎样直接从 JVM 内查找某个类的实例？
Arthas 支持 JDK 6+，支持 Linux/Mac/Windows，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。
如果您在使用 Arthas，请让我们知道，您的使用对我们非常重要：查看
