| Description | The number of discrete sampling intervals
over which data shall be saved in the part of
the rlHistory table associated with this
rlHistoryControlEntry.
When the associated rlHistoryControlBucketsRequested
object is created or modified, the probe
should set this object as closely to the requested
value as is possible for the particular
probe implementation and available resources. The
probe must not lower this value except as a result
of a modification to the associated
rlHistoryControlBucketsRequested object.
There will be times when the actual number of
buckets associated with this entry is less than
the value of this object. In this case, at the
end of each sampling interval, a new bucket will
be added to the rlHistory table.
When the number of buckets reaches the value of
this object and a new bucket is to be added to the
media-specific table, the oldest bucket associated
with this rlHistoryControlEntry shall be deleted by
the agent so that the new bucket can be added.
When the value of this object changes to a value less
than the current value, entries are deleted
from the rlHistory table. Enough of the oldest of these
entries shall be deleted by the agent so that their
number remains less than or equal to the new value of
this object.
When the value of this object changes to a value
greater than the current value, the number of
associated rlHistory table entries may be allowed to
grow. |
