For the application to forecast your resource utilization for a year, there must be at least 13 months of data stored in the Oracle IT Analytics warehouse. The forecast value is more accurate when there’s more data stored in the Oracle IT Analytics warehouse.

You can use the current and forecast storage utilization to plan your database capacity.
