SnmpAdminStringAn octet string containing administrative information, preferably in human-readable form. To facilitate internationalization, this information is represented using the ISO/IEC IS 10646-1 character set, encoded as an octet string using the UTF-8 transformation format described in [RFC2279]. Since additional code points are added by amendments to the 10646 standard from time to time, implementations must be prepared to encounter any code point from 0x00000000 to 0x7fffffff. Byte sequences that do not correspond to the valid UTF-8 encoding of a code point or are outside this range are prohibited. The use of control codes should be avoided. When it is necessary to represent a newline, the control code sequence CR LF should be used. The use of leading or trailing white space should be avoided. For code points not directly supported by user interface hardware or software, an alternative means of entry and display, such as hexadecimal, may be provided. For information encoded in 7-bit US-ASCII, the UTF-8 encoding is identical to the US-ASCII encoding. UTF-8 may require multiple bytes to represent a single character / code point; thus the length of this object in octets may be different from the number of characters encoded. Similarly, size constraints refer to the number of encoded octets, not the number of characters represented by an encoding. Note that when this TC is used for an object that is used or envisioned to be used as an index, then a SIZE restriction MUST be specified so that the number of sub-identifiers for any object instance does not exceed the limit of 128, as defined by [RFC3416]. Note that the size of an SnmpAdminString object is measured in octets, not characters. SIZE (0..255) · OCTET STRING · hint 255t

The textual name of the physical entity. The value of this object should be the name of the component as assigned by the local device and should be suitable for use in commands entered at the device's 'console'. This might be a text name (e.g., 'console') or a simple component number (e.g., port or module number, such as '1'), depending on the physical component naming syntax of the device. If there is no local name, or if this object is otherwise not applicable, then this object contains a zero-length string. Note that the value of entPhysicalName for two physical entities will be the same in the event that the console interface does not distinguish between them, e.g., slot-1 and the card in slot-1.

A textual description of physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity and should be set to a distinct value for each version or model of the physical entity.

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.

The most recent measurement obtained by the agent for this sensor. To correctly interpret the value of this object, the associated entPhySensorType, entPhySensorScale, and entPhySensorPrecision objects must also be examined.

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.

This object specifies the value of the threshold. The value of objects entPhySensorType, entPhysSensorScale and entPhySensorPrecision for this sensor entity defines how ceSensorExtThresholdValue can be displayed or intepreted by the user. entPhySensorValue can be compared with ceSensorExtThresholdValue without taking care of semantics of both objects.
