The ProTop Real-Time monitor can be thought of as a tower of lego blocks: you can add and remove sections (we call them data collectors) as you see fit. At startup, ProTop displays the "Dashboard" data collector, Table Activity, Index Activity and User IO Activity.
The contents of the title bar (top 2 lines) are explained below and each data collector is described in its own help page.
Left Side of the Title Bar
|Bottom||Full path of the database|
Center of the Title Bar
Right Side of the Title Bar
