'Add Discovery' or 'Discovery Error' in VADA
If you see the message Add discovery on a VADA or Enterprise Application (EA) map it means that a management pack can be imported to enable further objects to be discovered. Click on the message and follow the links to import the relevant management pack.
Dashboard Server v4.3 and above will show Add discovery, while v4.2 and below will show Discovery Error (see Discovery Error (VADA)) and when you click on the message it will give more information such as MISSING SCOM TASK or Discovery is disabled and information about importing the management pack. (see How to manage Dashboard Server MP dependencies).
