Property Description Supported

System(s)
• .. = DMTF Reserved
• 0x8000.. = Vendor Reserved
OperationalStatus replaces the Status property on ManagedSystemElement to provide a
consistent approach to enumerations, to address implementation needs for an array
property, and to provide a migration path from today's environment to the future. This
change was not made earlier because it required the deprecated qualifier. Due to the
widespread use of the existing Status property in management applications, it is strongly
recommended that providers or instrumentation provide both the Status and
OperationalStatus properties. Further, the first value of OperationalStatus should contain
the 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, and so on. 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.
NOTE: The value No Change (5) has been deprecated instead of indicating
the last requested state is Unknown (0). If the last requested or desired state
is unknown, RequestedState should have the value Unknown (0), but may
have the value No Change (5). Offline (6) indicates that the element has
been requested to transition to the Enabled but Offline EnabledState.
