For checking load during a movie you could just use top.
Yes but using top will require me to look non stop on top, and even then i could miss some 'spikes'.
When using logger I could watch movie and meanwhile log performance data.

Unless it's packaged as an addon you can't, unless you install the binaries manually somewhere on /storage.
Does LibreELEC support some common package typed like rpm or deb or I have to compile app myself ?
