The maximum number of groups of paths to record.
Specifically this is the number of hourly groups
to keep before rolling over.
The value of one is not advisable because the
group will close and immediately be deleted before
the network management station will have the
opportunity to retrieve the statistics.
The value used in the rttMonStatsCaptureTable to
uniquely identify this group is the
rttMonStatsCaptureStartTimeIndex.
HTTP and Jitter probes store only two hours of data.
When this object is set to the value of zero all
rttMonStatsCaptureTable data capturing will be shut off.
