CISCO-ENTITY-SENSOR-MIB
AI MIB Summary
The CISCO-ENTITY-SENSOR-MIB enables SNMP-based monitoring of physical sensor data, such as temperature, voltage, and fan speed, associated with entities within the Cisco Entity-MIB entPhysicalTable. It provides standardized access to real-time environmental and hardware status metrics for Cisco network devices to facilitate infrastructure health assessment and fault detection.
The CISCO-ENTITY-SENSOR-MIB is used to monitor the values of sensors in the Entity-MIB (RFC 2037) entPhysicalTable.

entSensorValueTableThis table lists the type, scale, and present value
of a sensor listed in the Entity-MIB entPhysicalTable. SEQUENCE OF EntSensorValueEntry .1.3.6.1.4.1.9.9.91.1.1.1 |
entSensorValueEntryAn entSensorValueTable entry describes the
present reading of a sensor, the measurement units
and scale, and sensor operational status. EntSensorValueEntry .1.3.6.1.4.1.9.9.91.1.1.1.1 |
entSensorTypeThis variable indicates the type of data
reported by the entSensorValue.
This variable is set by the agent at start-up
and the value does not change during operation.ro SensorDataType .1.3.6.1.4.1.9.9.91.1.1.1.1.1 |
entSensorScaleThis variable indicates the exponent to apply
to sensor values reported by entSensorValue.
This variable is set by the agent at start-up
and the value does not change during operation.ro SensorDataScale .1.3.6.1.4.1.9.9.91.1.1.1.1.2 |
entSensorPrecisionThis variable indicates the number of decimal
places of precision in fixed-point
sensor values reported by entSensorValue.
This variable is set to 0 when entSensorType
is not a fixed-point type: e.g.'percentRH(9)',
'rpm(10)', 'cmm(11)', or 'truthvalue(12)'.
This variable is set by the agent at start-up
and the value does not change during operation.ro SensorPrecision .1.3.6.1.4.1.9.9.91.1.1.1.1.3 |
entSensorValueThis variable reports the most recent measurement seen
by the sensor.
To correctly display or interpret this variable's value,
you must also know entSensorType, entSensorScale, and
entSensorPrecision.
However, you can compare entSensorValue with the threshold
values given in entSensorThresholdTable without any semantic
knowledge.ro SensorValue .1.3.6.1.4.1.9.9.91.1.1.1.1.4 |
entSensorStatusThis variable indicates the present operational status
of the sensor.ro SensorStatus .1.3.6.1.4.1.9.9.91.1.1.1.1.5 |

entSensorValuero TimeStamp (SNMPv2-TC) .1.3.6.1.4.1.9.9.91.1.1.1.1.6 |
entSensorValueUpdateRateThis variable indicates the rate that the agent
updates entSensorValue.ro SensorValueUpdateRate UNITS "seconds" .1.3.6.1.4.1.9.9.91.1.1.1.1.7 |
entSensorMeasuredEntityThis object identifies the physical entity for which the
sensor is taking measurements. For example, for a sensor
measuring the voltage output of a power-supply, this object
would be the entPhysicalIndex of that power-supply; for a sensor
measuring the temperature inside one chassis of a multi-chassis
system, this object would be the enPhysicalIndex of that
chassis.
This object has a value of zero when the physical entity
for which the sensor is taking measurements can not be
represented by any one row in the entPhysicalTable, or that
there is no such physical entity.ro EntPhysicalIndexOrZero (CISCO-TC) .1.3.6.1.4.1.9.9.91.1.1.1.1.8 |
entSensorThresholds OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.91.1.2 |
entSensorThresholdTableThis table lists the threshold severity, relation, and
comparison value, for a sensor listed in the Entity-MIB
entPhysicalTable. SEQUENCE OF EntSensorThresholdEntry .1.3.6.1.4.1.9.9.91.1.2.1 |
entSensorThresholdEntryAn entSensorThresholdTable entry describes the
thresholds for a sensor: the threshold severity,
the threshold value, the relation, and the
evaluation of the threshold.
Only entities of type sensor(8) are listed in this table.
Only pre-configured thresholds are listed in this table.
Users can create sensor-value monitoring instruments
in different ways, such as RMON alarms, Expression-MIB, etc.
Entries are created by the agent at system startup and
FRU insertion. Entries are deleted by the agent at
FRU removal. EntSensorThresholdEntry .1.3.6.1.4.1.9.9.91.1.2.1.1 |
entSensorThresholdIndexAn index that uniquely identifies an entry
in the entSensorThresholdTable. This index
permits the same sensor to have several
different thresholds. Integer32 .1.3.6.1.4.1.9.9.91.1.2.1.1.1 |
entSensorThresholdSeverityThis variable indicates the severity of this threshold.rw SensorThresholdSeverity .1.3.6.1.4.1.9.9.91.1.2.1.1.2 |
entSensorThresholdRelationThis variable indicates the relation between sensor value
(entSensorValue) and threshold value (entSensorThresholdValue),
required to trigger the alarm. when evaluating the relation,
entSensorValue is on the left of entSensorThresholdRelation,
entSensorThresholdValue is on the right.
in pseudo-code, the evaluation-alarm mechanism is:
...
if (entSensorStatus == ok) then
if (evaluate(entSensorValue, entSensorThresholdRelation,
entSensorThresholdValue))
then
if (entSensorThresholdNotificationEnable == true))
then
raise_alarm(sensor's entPhysicalIndex);
endif
endif
endif
...rw SensorThresholdRelation .1.3.6.1.4.1.9.9.91.1.2.1.1.3 |
entSensorThresholdValueThis variable indicates the value of the threshold.
To correctly display or interpret this variable's value,
you must also know entSensorType, entSensorScale, and
entSensorPrecision.
However, you can directly compare entSensorValue
with the threshold values given in entSensorThresholdTable
without any semantic knowledge.rw SensorValue .1.3.6.1.4.1.9.9.91.1.2.1.1.4 |
entSensorThresholdEvaluationThis variable indicates the result of the most
recent evaluation of the threshold. If the threshold
condition is true, entSensorThresholdEvaluation
is true(1). If the threshold condition is false,
entSensorThresholdEvaluation is false(2).
Thresholds are evaluated at the rate indicated by
entSensorValueUpdateRate.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.91.1.2.1.1.5 |
entSensorThresholdNotificationEnableThis variable controls generation of
entSensorThresholdNotification for this threshold.
When this variable is 'true', generation of
entSensorThresholdNotification is enabled for this
threshold. When this variable is 'false',
generation of entSensorThresholdNotification is
disabled for this threshold.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.91.1.2.1.1.6 |

entSensorThreshNotifGlobalEnableThis variable enables the generation of
entSensorThresholdNotification globally
on the device. If this object value is
'false', then no entSensorThresholdNotification
will be generated on this device. If this object
value is 'true', then whether a
entSensorThresholdNotification for a threshold will
be generated or not depends on the instance value of
entSensorThresholdNotificationEnable for that
threshold.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.91.1.3.1 |

entSensorThresholdNotificationThe notification is generated when
the sensor value entSensorValue crosses
the threshold value entSensorThresholdValue and
the value of entSensorThreshNotifGlobalEnable is true.

evaluation of threshold and generation of this
notification. NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.91.2.0.1 |
entSensorThresholdRecoveryNotificationThis notification is generated
as a recovery notification when
the sensor value entSensorValue goes below
the threshold value entSensorThresholdValue
once it has generated entSensorThresholdNotification.
The value of entSensorThreshNotifGlobalEnable needs
to be true.
