The Entity Sensor MIB contains a single entitySensorValueGroup that contains objects for representing values and status of the SFP/QSFP.
| Table/Group | Supported Variables | Comments |
|---|---|---|
| entitySensorValueGroup | entPhySensorType |
An integer that defines the type of data units for the sensor. Read-only. |
| enetPhySensorScale |
An integer representing the data scaling factor for the sensor. Read-only. |
|
| entPhySensorPrecision |
An integer representing the number of decimal places of sensor precision. Read-only. |
|
| entPhySensorValue |
An integer representing the sensor value. Read-only. |
|
| entPhyOperStatus |
Operational status of the sensor. |
|
| entPhySensorUnitsDisplay |
Text description of data units used in entPhySensorValue. Read-only. |
|
| entPhySensorValueTimeStamp |
Value of sysUpTime at the time the status and value was last obtained. Read-only. |
|
| entPhySensorValueUpdateRate |
Frequency that the agent updates the associated entPhySensorValue. Read-only. |
The entPhySensorType object is an integer that defines the sensor as one of the following types:.Value
| Value | Sensor Type |
|---|---|
| 1 | Other |
| 2 | Unknown |
| 3 | voltsAC |
| 4 | voltsDC |
| 5 | Amperes |
| 6 | Watts |
| 7 | Hertz |
| 8 | Celsius |
| 9 | percentRH |
| 10 | Rpm |
| 11 | Cmm |
| 12 | thruthvalue |
The following sensor types are used for the digital diagnostic monitoring data.
| Sensor | Sensor Type |
|---|---|
| Temperature | Celsius |
| VCC | voltsDC |
| Tx Bias Current | Amperes |
| Rx Power | Watts |
| Tx Power | Watts |
Power measurements may be represented as decibels (dB). If this is the case, the sensor type is defined as “other” and the units of measurement are determined using entPhySensorUnitsDisplay.
The entPhySensorScale object is an integer that defines the scale of the sensor as one of the following.
| Value | Sensor Scale |
|---|---|
| 1 | Yocto |
| 2 | Zepto |
| 3 | Atto |
| 4 | femto |
| 5 | Pico |
| 6 | nano |
| 7 | micro |
| 8 | milli |
| 9 | units |
| 10 | Kilo |
| 11 | mega |
| 12 | giga |
| 13 | tera |
| 14 | Exa |
| 15 | peta |
| 16 | zetta |
| 17 | yotta |
This object defines the sensor precision range.
A value in the range 1 to 9, represents the number of decimal places in the fractional part of an associated entPhySensorValue fixed-point number. A value in the range -8 to -1, represents the number of accurate digits in the associated entPhySensorValue fixed-point number. The value zero indicates the associated entPhySensorValue object is not a fixed-point number.
The entPhySensorValue object is the value of the sensor.
The entPhySensorOperStatus object is an integer that defines the operating status of the sensor as one of the following.
| Value | Sensor Status |
|---|---|
| 1 | Ok |
| 2 | Unavailable |
| 3 | Nonoperational |
Ports without a populated transceiver or one that is unreachable due to i2c bus errors, etc. are designated “nonoperational”. Ports populated with a transceiver that does not support digital diagnostic monitoring are designated “unavailable.”
The entPhySensorUnitsDisplay object is a textual description of the data units that should be used in the display of entPhySensorValue.
The entPhySensorValueTimeStamp object is the value of sysUpTime at the time the status and/or value of this sensor were last obtained.
The entPhySensorValueUpdateRate object is an indication of the frequency that the agent updates the associated entPhySensorValue object, represented in milliseconds.
