Delta-Schwellenwert

System.Performance.DeltaThreshold (UnitMonitorType)

Der Monitor wechselt den Status, wenn die über eine bestimmte Anzahl von Abtastungen berechnete Veränderung des Leistungsindikators (Anstieg oder Abfall) den Schwellenwert übersteigt. Ein negativer Deltawert bedeutet einen Abfall des Leistungsindikators.
