Using the Monitor

The monitor provides four overviews that follow on from each other:

       1.      Areas

       2.      Area instances

       3.      Versions

       4.      Locks

Double-clicking on a row in the current overview takes you to the next overview, for example from the overview of area instances to the list of versions of this area instance. From the instance overview you can display the list of locks on a parallel tab page.

In the list of areas, area instances and area instance versions you can select a view, which groups the data that is displayed. The following views are available:

·        Overview (displays the most important data)

·        Locks (lock statistics)

·        Users (who created/modified the area)

·        Control (memory usage and so on)

·        All columns
