Site Usage 'Run Report' Button - Struggling to understand the output?

[Toby McDaid]

We've had one of our site administrators notice the 'run report' button at the bottom of the site usage page on a SharePoint site. 

Having taken an initial look at the .CSV report that it outputs, I am confused as to what this report is supposed to be showing (see screenshot below).

• Is the Resource Path just the area of the site the user has visited? Or is it that they have permissions to this area? Ownership of this area?
• The User Name column displays some fields as group names (e.g. visitors, owners, members) and other fields as actual user names. One user listed there doesn't even have permissions to this site but her name appears on the report?

I don't know if anyone has used this report before and could help me to understand the information, any help would be great!

Those are the Sharing Reports for the site so every records shows a folder or file shared from the site

Ah, that makes sense. So are the user names the names of people who received the shared folder/file, or the names of the people who sent them? There is a user listed there who has never accessed the site before.
