entSensorType |
.1.3.6.1.4.1.9.9.91.1.1.1.1.1 |
This 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.
|
entSensorScale |
.1.3.6.1.4.1.9.9.91.1.1.1.1.2 |
This 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.
|
entSensorPrecision |
.1.3.6.1.4.1.9.9.91.1.1.1.1.3 |
This 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: voltsAC(1), voltsDC(2),
amperes(3), watts(4), hertz(5), celsius(6), or cmm(9).
This variable is set by the agent at start-up
and the value does not change during operation.
|
entSensorValue |
.1.3.6.1.4.1.9.9.91.1.1.1.1.4 |
This 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.
|
entSensorStatus |
.1.3.6.1.4.1.9.9.91.1.1.1.1.5 |
This variable indicates the present operational status
of the sensor.
|
entSensorValueTimeStamp |
.1.3.6.1.4.1.9.9.91.1.1.1.1.6 |
This variable indicates the age of the value reported by
entSensorValue
|
entSensorValueUpdateRate |
.1.3.6.1.4.1.9.9.91.1.1.1.1.7 |
This variable indicates the rate that the agent
updates entSensorValue.
|
entSensorThresholdIndex |
.1.3.6.1.4.1.9.9.91.1.2.1.1.1 |
An index that uniquely identifies an entry
in the entSensorThreshold table. This index
permits the same sensor to have several
different thresholds.
|
entSensorThresholdSeverity |
.1.3.6.1.4.1.9.9.91.1.2.1.1.2 |
This variable indicates the severity of this threshold.
|
entSensorThresholdRelation |
.1.3.6.1.4.1.9.9.91.1.2.1.1.3 |
This 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(entSensorThresholdAlarmOID);
endif
endif
endif
...
|
entSensorThresholdValue |
.1.3.6.1.4.1.9.9.91.1.2.1.1.4 |
This 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.
|
entSensorThresholdEvaluation |
.1.3.6.1.4.1.9.9.91.1.2.1.1.5 |
This 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.
|
entSensorThresholdNotificationEnable |
.1.3.6.1.4.1.9.9.91.1.2.1.1.6 |
This variable controls generation of
entSensorThresholdNotification for this threshold.
When this variable is true(1), generation of
entSensorThresholdNotification is enabled. When this
variable is false(2), generation of
entSensorThresholdNotification is disabled.
This variable only controls generation of
entSensorThresholdNotification.
