EnergyPlus Output:Diagnostics

From an EnergyPlus .err file it advised adding the following: Output:Diagnostics,DisplayExtraWarnings; So, it was added to the idf, reran simulation, it crashed.... but where do are these additional error details found?

Full error: * Severe * GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3. * ~~~ * These surfaces should be deleted. * ~~~ * For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;
