Contains indicators of the current status of the element. The first value of the OperationalStatus property should contain the primary status for the element.
Note
The OperationalStatus property replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, we strongly recommend that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status, because it is a single-valued property, should also provide the primary status of the element.

Indicates that the element functions, but requires attention. Overload and overheated are examples of Stressed states.
Predictive Failure (5)
Indicates that an element functions nominally, but predicts a failure in the near future.

Indicates that the monitoring system has information about this element, but has never been able to establish communications with it.
Lost Communication (13)
Indicates that the monitoring system has successfully contacted this element in the past, but it is currently unavailable.
Aborted (14)
Indicates that the job stopped in an unexpected way. The state and configuration of the job might require an update.
Dormant (15)
Indicates that the job is inactive.
Supporting Entity in Error (16)

Completed (17)
Indicates that the job has completed its operation. This value should be combined with either OK, Error, or Degraded to indicate to a client whether the complete operation Completed with OK and passed, or completed with Error and failed, or completed with Degraded and finished the operation, but did not complete OK or did not report an error.
