An entry describes the data collected for an interval.
The system creates a row in the ceshCollectionIntervalTable
after it has sampled a sample for a given collection.
The maximum allowable entries for a collection should be less
than or equal to the value specified by
ceshCollectionMaxIntervals instance. Once number of entries is
equal to ceshCollectionMaxIntervals, then the system destroys
the lease recent row from the collection before creating a new
one.
An agent destroys all conceptual entries corresponding to a
physical entity upon removal of the physical entity.
