Entity Sensor Management Information Base

Abstract

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Monitoring and Control MIB for Power and Energy

“…The ENTITY-SENSOR MIB [RFC3433] does not have the ANSI C12.x accuracy classes required for electricity (e.g., 1%, 2%, and 0.5% accuracy classes). Indeed, entPhySensorPrecision [RFC3433] represents "The number of decimal places of precision in fixed-point sensor values returned by the associated entPhySensorValue object".…”

“…Indeed, entPhySensorPrecision [RFC3433] represents "The number of decimal places of precision in fixed-point sensor values returned by the associated entPhySensorValue object". The ANSI and IEC standards are used for power measurement and these standards require that we use an accuracy class, not the scientific-number precision model specified in RFC3433.…”

“…Note that, even though the Power-over-Ethernet MIB [RFC3621] was created after the ENTITY-SENSOR MIB [RFC3433], it does not reuse the precision notion from the ENTITY-SENSOR MIB, i.e., the entPhySensorPrecision MIB object.…”

Group Communication for the Constrained Application Protocol (CoAP)

“…These alternative approaches may support a subset or superset of the membership configuration RESTful interface described in this document. For example, a simple interface to just read the endpoint group information may be implemented via a classical Management Information Base (MIB) approach (e.g., following the approach of [RFC3433]). …”

An Overview of the IETF Network Management Standards

“…Physical entities can have pointers to other data models that provide more specific information about them (e.g., physical ports usually point to the related network interface). Entity MIB extensions exist for physical sensors such as temperature sensors embedded on line cards or sensors that report fan rotation speeds [RFC3433]. The Entity State MIB [RFC4268] models states and alarms of physical entities.…”
