Name
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (1024)
The label by which the object is known. When subclassed, the Name property can be overridden to be a key property.
This property is inherited from CIM_ManagedSystemElement.
OperationalStatus
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")
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.
This property is inherited from CIM_ManagedSystemElement.
The possible values are.
Unknown (0)
Indicates that the implementation cannot report on the OperationalStatus property at this time.
Other (1)
Indicates an undefined state.
OK (2)
Indicates full functionality without errors.
Degraded (3)
Indicates that the element is in working order and that all functionality is provided. However, the element does not function to the best of its abilities. For example, the element might not operate at optimal performance, or it might report recoverable errors.
Stressed (4)
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.
Error (6)
Indicates that an error has occurred.
Non-Recoverable Error (7)
Indicates that a nonrecoverable error has occurred.
Starting (8)
Indicates that the job is starting.
Stopping (9)
Indicates that the job is stopping.
Stopped (10)
Indicates that the element has been intentionally stopped.
In Service (11)
Indicates that the element is in process to be configured, maintained, cleaned, or otherwise administered.
No Contact (12)
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)
Indicates that an element on which this job depends is in error. This element might be OK but cannot function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.
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.
Power Mode (18)
Indicates that the element has additional power model information that is contained in the associated power management service.
