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. +----------------------------------------------+ | ceshCollectionTable | | +------------------------------------------+ | | | ceshCollectionEntry | | | | entPhysicalIndex = 3 | | | | ceshCollectionIntervalTime = 60 | | | | ceshCollectionIntervals = 60 | | | | ceshCollectionInvalidIntervals = 0 |-----+ | | ceshCollectionMaxIntervals = 60 | | | | | ceshCollectionElapsedTime = 20 | | | | | ceshCollectionAlgorithm = 3 | | | | +------------------------------------------+ | | | +------------------------------------------+ | | | | ceshCollectionEntry | | | | | entPhysicalIndex = 3 | | | | | ceshCollectionIntervalTime = 3660 | | | | | ceshCollectionIntervals = 2 |------------+ | | ceshCollectionInvalidIntervals = 0 | | | | | | ceshCollectionMaxIntervals = 60 | | | | | | ceshCollectionElapsedTime = 20 | | | | | | ceshCollectionAlgorithm = 4 | | | | | +------------------------------------------+ | | | +----------------------------------------------+ | | | | +----------------------------------------------+ | | | ceshCollectionIntervalTable | | | | +------------------------------------------+ | | | | | ceshCollectionIntervalEntry | | | | | | entPhysicalIndex = 3 |<----+ | | | ceshCollectionIntervalTime = 60 | | | | | | ceshCollectionIntervalNumber = 1 | | | | | | ceshCollectionIntervalSensorValue = 54 | | | | | | ceshCollectionIntervalTimeStamp = 1 | | | | | +------------------------------------------+ | | | | .................... <----+ | | skipped 58 entries <----+ | | .................... <----+ | | | | | | +------------------------------------------+ | | | | | ceshCollectionIntervalEntry | | | | | | entPhysicalIndex = 3 |<----+ | | | ceshCollectionIntervalTime = 60 | | | | | ceshCollectionIntervalNumber = 60 | | | | | ceshCollectionIntervalSensorValue = 54 | | | | | ceshCollectionIntervalTimeStamp = 60 | | | | +------------------------------------------+ | | | | | | +------------------------------------------+ | | | | ceshCollectionIntervalEntry | | | | | entPhysicalIndex = 3 |<-----------+ | | ceshCollectionIntervalTime = 3660 | | | | ceshCollectionIntervalNumber = 1 | | | | ceshCollectionIntervalSensorValue = 54 | | | | ceshCollectionIntervalTimeStamp = 60 | | | +------------------------------------------+ | +----------------------------------------------+ 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.

Index: entPhysicalIndex · ceshCollectionIntervalTime
This 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.

PhysicalIndexAn arbitrary value that uniquely identifies the physical entity. The value should be a small positive integer. Index values for different physical entities are not necessarily contiguous. (1..2147483647) · Integer32 · hint d

Gauge32 · intervals
This 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.

SensorHistoryCollectionAlgorithm1 = other2 = unknown3 = measured4 = algoSMAThis textual convention denotes an enumerated integer-value that describing the method used to collect historic data for a sensor. 'other' - The implementation of the MIB module using this textual convention does not recognize the historic data collection algorithm. 'unknown' - The system is not able to ascertain the historic data collection algorithm. 'measured' - A raw value. 'simpleAverage' - The system collects a simple moving average of the values sampled from the sensor. · Integer32
This object indicates the algorithm used in collecting historic data from the corresponding sensor.

This 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).

EntitySensorValueAn object using this data type represents an Entity Sensor value. An object of this type SHOULD be defined together with objects of type EntitySensorDataType, EntitySensorDataScale and EntitySensorPrecision. Together, associated objects of those three types are used to identify the semantics of an object of this data type. The semantics of an object using this data type are determined by the value of the associated EntitySensorDataType object. If the associated EntitySensorDataType object is equal to 'voltsAC(3)', 'voltsDC(4)', 'amperes(5)', 'watts(6), 'hertz(7)', 'celsius(8)', or 'cmm(11)', then an object of this type MUST contain a fixed point number ranging from -999,999,999 to +999,999,999. The value -1000000000 indicates an underflow error. The value +1000000000 indicates an overflow error. The EntitySensorPrecision indicates how many fractional digits are represented in the associated EntitySensorValue object. If the associated EntitySensorDataType object is equal to 'percentRH(9)', then an object of this type MUST contain a number ranging from 0 to 100. If the associated EntitySensorDataType object is equal to 'rpm(10)', then an object of this type MUST contain a number ranging from -999,999,999 to +999,999,999. If the associated EntitySensorDataType object is equal to 'truthvalue(12)', then an object of this type MUST contain either the value 'true(1)' or the value 'false(2)'. If the associated EntitySensorDataType object is equal to 'other(1)' or unknown(2)', then an object of this type MUST contain a number ranging from -1000000000 to 1000000000.

This 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).

TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be defined in the description of any object defined using this type. If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks
This object indicates the value of sysUpTime when the system sampled the corresponding sensor.
