1. A method of predicting a performance shortage of an application, the method comprising: monitoring at least one performance parameter of the application to generate performance data; using said performance data to compute a mathematic function describing a time dependent development of said performance parameter; using said mathematical function to compute a point in time when the performance parameter will exceed a selected threshold; and communicating a prediction to a person if said point in time lies within a pre-determined timeframe, wherein the prediction indicates that a performance shortage of the application is expected near said point in time.
