I don't think this information is logged and stocked somewhere.
However, you can monitor the activities of all the users.
If you have administrator privileges then log in to tableau server on web. You will have server tab at the top.
Where you will get all the information about the current status of server.
If you scroll bit down then there are few options. Go to analysis where you will get more information about all the activities.
