AdslPerfCurrDayCount
A counter associated with interface performance measurements in a current 1-day (24 hour) measurement interval. The value of this counter starts at zero at the beginning of an interval and is increased when associated events occur, until the end of the 1-day interval. At that time the value of the counter is stored in the previous 1-day history interval, if available, and the current interval counter is restarted at zero. In the case where the agent has no valid data available for this interval the corresponding object instance is not available and upon a retrieval request a corresponding error message shall be returned to indicate that this instance does not exist (for example, a noSuchName error for SNMPv1 and a noSuchInstance for SNMPv2 GET operation).
