is it possible to restart an extension via cli?

[Bazon Bloch <bazonbloch arcor de>]

Hello,

since recently I have a problem with 
https://extensions.gnome.org/extension/120/system-monitor/ :
after resume from standby, the CPU graph remains a flat line, that means 
the values aren't refreshed.
(although gnome-system-monitor works)

to get the CPU graph working again, I can restart gnome-shell with 
alt+f2 r, but i'd like to avoid the time that takes.

so what i would like to have (apart from not having the problem in the 
first place) is a possibility to just restart that extension via a cli 
command. (that could be executed automatically on resume.)

is there a possibility to do that?

thanks,
Bazon.
