Scripts for additional suspension checks

[offlinehacker]

Idea

Implement a scripts that checks whether suspension is needed or not based on current process behavior. Have an option which scripts to activate for a profile.

Example checks

• Does application play sound or not by checking pulse audio inputs.

pacmd list-sink-inputs short command gives information which processes are playing sound, also PID of process

• Is application under high CPU load

If application is under high CPU load it might not be wise to suspend processes, as it might be processing something.

• Is application having high network traffic lately

If application is having high network traffic it might not be wise to suspend processes, as it might be downloading or uploading something.

How about a library of common, reusable shell scripts that ships with the software? Then we can prefix PATH before executing exec_suspend script, and the user can simply do:

...
exec_suspend = is-not-playing-sound && ...

That's a good idea, and it's then simple to package it and place these scripts under libexec :)

I use this to check if my webcam is in use. If it is, it avoids suspending chrome.
exec_suspend = sh -c 'exit $(lsmod | grep "^uvcvideo " | awk "{ print $3 }")'
