Sharepoint document library retrieve view statistics

Hello the community,

I am using Power BI in order to try to get deeper statistics than the site usage feature offered by Sharepoint which I think is very poor

So I managed on document library to get file size data, folder size, size ventillation by tags, file type, etc.... 

but nothing concerning files user viewing count on my documentary library, or the pages viewing count from my News app.

I'would like to find the same kind of information than Sharepoint site usage feature, but with more deeper details/flexible where you can choose your period on time, if you want view stat on the whole sharepoint or on only on the document library etc...

And I did not find this kind of info when I connected my Power BI to my document library from my Sharepoint site

But maybe I did not look at the right place.

I hope it is possible,

Thanks for your help
