Description: This MIB module defines objects that describe collections and
measurement information for each sensor supporting historical 
data collection.  The sensor measurement either represents a
measured value or a SMA (Simple Moving Average) value for a
specified interval rate over a period of time.

This MIB module defines two tables relating to sensor measured
value, including:

    o ceshCollectionTable - contains data describing a  
          collection of historic data for a sensor.

    o ceshCollectionIntervalTable - contains zero or more rows 
          containing historic data for a sensor

The figure below illustrates the relationship between these two
tables.

If the system samples a sensor every minute for one collection
and every hour for another, then the ceshCollectionTable
contains two entries describing the two collections.
