<p>当你遇到以下类似问题而束手无策时，你看到了这篇文档，看到了 <code class="docutils literal notranslate"><span class="pre">Arthas</span></code>，那么恭喜你，你朝正确的方向又迈了一大步。</p>
<ol class="simple">
<li>这个类从哪个 jar 包加载的？为什么会报各种类相关的 Exception？</li>
<li>我改的代码为什么没有执行到？难道是我没 commit？分支搞错了？</li>
<li>遇到问题无法在预发 debug 一下，难道只能通过加日志再重新预发布吗？</li>
<li>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！</li>
<li>是否有一个全局视角来查看系统的运行状况？</li>
<li>有什么办法可以监控到容器和中间件（AliTomcat、HSF、Notify 等）的实时运行状态？</li>
</ol>
<p><code class="docutils literal notranslate"><span class="pre">Arthas</span></code> 是全新的在线诊断工具，采用命令行交互模式，支持web端在线诊断，同时提供丰富的 <code class="docutils literal notranslate"><span class="pre">Tab</span></code> 自动补全功能，进一步方便进行问题的定位和诊断。</p>
