How do i know which of my users is consuming/opening the most maps?

Hello, i didn't know if asking this here or on the Wialon Hosting Forum but either way my question is:
Since im using a google maps API Key, Is there a way to see wich of my users in consuming/opening the most maps on the platform?
Google just tells me how much API Request im using but ill like to know wich of my users is consuming the most.

Any help is very appreciated
