ENTITY-SENSOR-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

Copyright (C) The Internet Society (2002). This version of this MIB module is part of RFC 3433; see the RFC itself for full legal notices." REVISION "200212160000Z" DESCRIPTION "Initial version of the Entity Sensor MIB module, published as RFC 3433." ::= { mib-2 99 } entitySensorObjects OBJECT IDENTIFIER ::= { entitySensorMIB 1 } -- entitySensorNotifications OBJECT IDENTIFIER -- ::= { entitySensorMIB 2 } entitySensorConformance OBJECT IDENTIFIER ::= { entitySensorMIB 3 } -- -- Textual Conventions -- EntitySensorDataType ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An object using this data type represents the Entity Sensor measurement data type associated with a physical sensor value. The actual data units are determined by examining an object of this type together with the associated EntitySensorDataScale object. An object of this type SHOULD be defined together with objects of type EntitySensorDataScale and EntitySensorPrecision. Together, associated objects of these three types are used to identify the semantics of an object of type EntitySensorValue.

The actual data units are determined by examining an object of this type together with the associated EntitySensorDataType object. An object of this type SHOULD be defined together with objects of type EntitySensorDataType and EntitySensorPrecision.

An object of this type SHOULD be defined together with objects of type EntitySensorDataType and EntitySensorDataScale. Together, associated objects of these three types are used to identify the semantics of an object of type EntitySensorValue. If an object of this type contains a value in the range 1 to 9, it represents the number of decimal places in the fractional part of an associated EntitySensorValue fixed- point number. If an object of this type contains a value in the range -8 to -1, it represents the number of accurate digits in the associated EntitySensorValue fixed-point number. The value zero indicates the associated EntitySensorValue object is not a fixed-point number. Agent implementors must choose a value for the associated EntitySensorPrecision object so that the precision and accuracy of the associated EntitySensorValue object is correctly indicated. For example, a physical entity representing a temperature sensor that can measure 0 degrees to 100 degrees C in 0.1 degree increments, +/- 0.05 degrees, would have an EntitySensorPrecision value of '1', an EntitySensorDataScale value of 'units(9)', and an EntitySensorValue ranging from '0' to '1000'. The EntitySensorValue would be interpreted as 'degrees C * 10'." SYNTAX Integer32 (-8..9) EntitySensorValue ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An 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."
