Property Description
primary status for the element. When instrumented,
Status (because it is single-valued) should also provide
the primary status of the element.
PossibleStates
Enumerates the string outputs of the Sensor.
Example 1 - A "Switch" Sensor may output the states "On",
or "Off". Another implementation of the Switch may output
the states "Open", and "Close".
Example 2 - is a NumericSensor supporting thresholds.
This Sensor can report the states like "Normal", "Upper
Non-Critical", "Lower Non-Critical", etc. A NumericSensor
that does not publish readings and thresholds, but stores
this data internally, can still report its states.
RateUnits
Specifies if the units returned by this Sensor are rate
units. All the values returned by this Sensor are
represented in the units obtained by (BaseUnits * 10
raised to the power of the UnitModifier). This is true
unless this property (RateUnits) has a value different than
"None". For example, if BaseUnits is Volts and the
UnitModifier is -6, then the units of the values returned
are MicroVolts. But, if the RateUnits property is set to a
value other than "None", then the units are further
qualified as rate units. In the above example, if RateUnits
is set to "Per Second", then the values returned by the
Sensor are in MicroVolts/Second. The units apply to all
numeric properties of the Sensor, unless explicitly
overridden by the Units qualifier. Any implementation of
CurrentReading should be qualified with either a Counter
or a Gauge qualifier, depending on the characteristics of
the sensor being modeled.
Possible values are:
• 0 = None
• 1 = Per MicroSecond
• 2 = Per MilliSecond
• 3 = Per Second
• 4 = Per Minute
• 5 = Per Hour
• 6 = Per Day
• 7 = Per Week
• 8 = Per Month
• 9 = Per Year
RequestedState
An integer enumeration that indicates the last requested
or desired state for the element, irrespective of the
mechanism through which it was requested. The actual
state of the element is represented by EnabledState. This
property is provided to compare the last requested and
current enabled or disabled states. Note that when
EnabledState is set to 5 ("Not Applicable"), then this
property has no meaning. Refer to the EnabledState
property description for explanations of the values in the
RequestedState enumeration.
