This is a demo on how to handle remote process execution in asyncio

Obviously don't use in production as there's no auth.

• Supports starting processes and killing them
• Streams stdin/out/err
• Optional PTY mode with resizing support

memuse measures unique physical total memory taken by a process and its children, ignoring duplicate copy-on-write pages and shared memory.

This is a solution for http://serverfault.com/questions/676335/how-measure-memory-without-copy-on-write-pages

It's a quick and dirty utility, but feel free to fork & improve.

Example:

~ » sudo ./memuse.py 15897                                                                                                                         eugene@eugene-thinkpad
