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. |
