CISCO-ENTITY-SENSOR-HISTORY-MIB
AI MIB Summary
The CISCO-ENTITY-SENSOR-HISTORY-MIB enables the retrieval of historical measurement data, including Simple Moving Average (SMA) values, for physical sensors on Cisco hardware via the `ceshCollectionTable` and `ceshCollectionIntervalTable`. This module facilitates time-series analysis of environmental parameters such as temperature, voltage, and fan speed by storing aggregated sensor readings at configurable intervals.
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.

ciscoEntitySensorHistoryMIBThis 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. MODULE-IDENTITY .1.3.6.1.4.1.9.9.768 |
ciscoEntitySensorHistoryMIBObjects OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.768.0 |
ceshCollectionTableThis table lists each collection of historic data maintained
by the system for each supported sensor.
This table has an expansion dependent relationship on the
ceshCollectionIntervalTable, containing zero or more rows for
each corresponding collection. SEQUENCE OF CeshCollectionEntry .1.3.6.1.4.1.9.9.768.0.1 |
ceshCollectionEntryEach entry in the ceshCollectionTable contains collection
attributes describing the collection.
For each supported sensor, the system creates a row
for each prescribed collection. This creation process happens
at startup and following the insertion of a FRU containing
sensors.
The system destroys a row when it destroys the corresponding row
in the entPhysicalTable, which can happen as the result of the
removal of the FRU containing the sensor. CeshCollectionEntry .1.3.6.1.4.1.9.9.768.0.1.1 |
ceshCollectionIntervalTimeThis object indicates the length of the sampling interval for
the collection. Unsigned32 .1.3.6.1.4.1.9.9.768.0.1.1.1 |

has been collected.ro Gauge32 UNITS "intervals" .1.3.6.1.4.1.9.9.768.0.1.1.2 |
ceshCollectionInvalidIntervalsThis object indicates the number of intervals in the range of
'0' to the value of the corresponding instance of
ceshCollectionIntervals, for which no data is available.
The value of this column will typically be '0', except in
certain circumstances when some intervals are not available.ro Gauge32 UNITS "intervals" .1.3.6.1.4.1.9.9.768.0.1.1.3 |

This table has an expansion dependent relationship on the
ceshCollectionTable, containing zero or more rows for each
corresponding collection. SEQUENCE OF CeshCollectionIntervalEntry .1.3.6.1.4.1.9.9.768.0.2 |
ceshCollectionIntervalEntryAn 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. CeshCollectionIntervalEntry .1.3.6.1.4.1.9.9.768.0.2.1 |
ceshCollectionIntervalNumberThis object indicates the interval number identifying the
interval. The interval identified by the value '1' represents
the most recent interval, and the interval identified by the
value (n) represents the interval immediately preceding the
interval identified by the value (n-1). Unsigned32 .1.3.6.1.4.1.9.9.768.0.2.1.1 |
ceshCollectionIntervalSensorValueThis object indicates the sensor value for the corresponding
physical entity during the interval.
To correctly display or interpret this variable's value, you
must also know the sensor's type, scale, and precision
indicated by the corresponding entry in the entPhySensorTable
(defined by the ENTITY-SENSOR-MIB) or entSensorValueTable
(defined by the CISCO-ENTITY-SENSOR-MIB).ro EntitySensorValue (ENTITY-SENSOR-MIB) .1.3.6.1.4.1.9.9.768.0.2.1.2 |
