The number of seconds left in the report currently being collected. When this object is modified by the management station, a new collection is started, possibly aborting a currently running report. The new value is used as the requested duration of this report, and is immediately loaded into the associated nlMatrixTopNControlDuration object. When the report finishes, the probe will automatically start another collection with the same initial value of nlMatrixTopNControlTimeRemaining. Thus the management station may simply read the resulting reports repeatedly, checking the startTime and duration each time to ensure that a report was not missed or that the report parameters were not changed.

While the value of this object is non-zero, it decrements by one per second until it reaches zero. At the time that this object decrements to zero, the report is made accessible in the nlMatrixTopNTable, overwriting any report that may be there.

When this object is modified by the management station, any associated entries in the nlMatrixTopNTable shall be deleted.

(Note that this is a different algorithm than the one used in the hostTopNTable).
