Using drilldowns

Drilldowns display detailed information about the domain controller you are analyzing.

The Diagnostic Console is designed to help you locate and identify problem areas quickly using a visual representation of the major components in the domain controller being monitored. When you have isolated a problem, you can see a detailed breakdown by viewing a drilldown that displays the underlying statistics.

You can display drilldowns by clicking a component in the main screen or by clicking a drilldown button on the toolbar. You can modify the way drilldowns display information.

Each drilldown page contains displays that provide you with specific information about the components of your system. Drilldowns mainly use two different types of displays - tables and charts. Drilldowns have the following features:

The Diagnostic Console provides the following drilldowns:
