As a consultant, I have a number of FileMaker Servers that I administer.
If I open more than one Admin Console, each one has a tab (or window name) of FileMaker Server Admin Console.
The only way to know which one is which, is to navigate to the Status Page to see the Host Name.
The Host Name should be more prominently displayed.
I suggest, two places.
1. In the Window or Tab name --> FileMaker Server <<HostName>> Console
2. In the header area of the web page, where it now says FileMaker Server 15 --> FileMaker Server (<<HostName>>)
but really any where else would be OK, so I know what server I am looking at.
