statuses are defined. Many of the enumeration's values are
self-explanatory. However, a few are not and are described in more
detail.
"Stressed" indicates that the element is functioning, but needs attention.
Examples of "Stressed" states are overload, overheated, etc.
"Predictive Failure" indicates that an element is functioning nominally
but predicting a failure in the near future.
"In Service" describes an element being configured, maintained,
cleaned, or otherwise administered.
"No Contact" indicates that the monitoring system has knowledge of
this element, but has never been able to establish communications with
it.
"Lost Communication" indicates that the ManagedSystemElement is
known to exist and has been contacted successfully in the past, but is
currently unreachable.
"Stopped" and "Aborted" are similar, although the former implies a
clean and orderly stop, while the latter implies an abrupt stop where
the element's state and configuration may need to be updated.
"Dormant" indicates that the element is inactive or quiesced.
"Supporting Entity in Error" describes that this element may be "OK"
but that another element, on which it is dependent, is in error. An
example is a network service or endpoint that cannot function due to
lower layer networking problems.
"Completed" indicates the element has completed its operation. This
value should be combined with either OK, Error, or Degraded so that a
client can till if the complete operation passed (Completed with OK),
and failure (Completed with Error). Completed with Degraded would
imply the operation finished, but did not complete OK or report an
error.
"Power Mode" indicates the element has additional power model
information contained in the Associated PowerManagementService
association.
PossibleStates enumerates the string outputs of the Sensor. For example,
a "Switch" Sensor may output the states "On", or "Off". Another
implementation of the Switch may output the states "Open", and
"Close". Another example is a NumericSensor supporting thresholds.
This Sensor can report the states like "Normal", "Upper Fatal", "Lower
Non-Critical", etc. A NumericSensor that does not publish readings
and thresholds, but stores this data internally, can still report its states.
The current state indicated by the Sensor. This is always one of the
"PossibleStates".
The base unit of the values returned by this Sensor. All the values
returned by this Sensor are represented in the units obtained by
(BaseUnits * 10 raised to the power of the UnitModifier). For example,
if BaseUnits is Volts and the UnitModifier is -6, then the units of the
values returned are MicroVolts.
The unit multiplier for the values returned by this Sensor. All the values
returned by this Sensor are represented in the units obtained by
(BaseUnits * 10 raised to the power of the UnitModifier). For example,
if BaseUnits is Volts and the Unit Modifier is -6, then the units of the
values returned are MicroVolts.
The current value indicated by the sensor.
