It really depends on what you are looking for in this case. Either the logs or Tableau Server's repository may have the answer. Since you had mentioned the Admin Views, I'll assume you are searching for better reporting overall.
If we want to use an Admin View which is better, faster, stronger then we will need to follow these steps:
1. Allow users to access Tableau Server database
2. From Tableau Desktop, connect
At this point we can go one of two ways. The first is to search our Server Admin group for pre-fabricated workbooks created by our peers: New Views for Tableau Server Administrators — BI on BI
The second, and generally more painful, method is to use the following resources in order to create your own workbook:
Workgroups Database (this is the one where you can find the table which stores ClientIP)

If this information doesn't quite cut it, let me know and I'll see if we can zero on something more useful.
