Question

我们在Passenger 5.0.30服务器中运行Ubuntu 12.04服务器，当我们运行sudo passenger-status时，我们会收到非常有用和简明的信息。要获得更多信息，可以选择sudo passenger-status --show=requests，但这只是为了快速识别某些请求甚至服务器的问题。

有没有办法在sudo passenger-status输出中包含每个进程正在运行的当前操作？如果没有，关于如何创建可能是解析此信息并输出我需要的命令的任何想法或建议？

sudo passenger-status输出示例：

sudo passenger-status --show=requests输出的示例（我会对path属性特别感兴趣）：

如果您对python感到满意（甚至不熟悉），则可以执行以下操作：

false

输出应采用以下方式：

clipChildren

类似地，您也可以检索请求/线程的其他重要参数。
