InstallDate
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")
Indicates when the object was installed. The lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
InstanceID
-
Data type: string
-
Access type: Read-only
Uniquely and opaquely identifies an instance of this class within the scope of the containing namespace.
[!Important]
In order to ensure uniqueness within the namespace, the value of the InstanceID property should be constructed in the following pattern: OrgID:LocalID
OrgID must include a copyrighted, trademarked or otherwise unique name that is owned by the business entity that defines the InstanceID, or be a registered ID that is assigned by a recognized global authority. This pattern is similar to the structure of schema class names. In addition, to ensure uniqueness, the first colon in InstanceID must be between the OrgID andLocalID. Therefore the OrgID must not contain a colon (':').
LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.
If the above pattern is not used, the defining entity must assure that the resultant InstanceID value is not re-used across any InstanceID properties that are produced by this provider or other providers for this namespace.
For Distributed Management Task Force (DMTF) defined instances, the pattern must be used with the OrgID set to CIM.
This property is inherited from CIM_ManagedElement.
Name
A unique identifier of the service that indicates the functionality of the service.
This property is inherited from CIM_Service.

This property is inherited from CIM_ManagedSystemElement.
Unknown (0)
Indicates that the instrumentation cannot report on the OperatingStatus property at this time.

Indicates that the instrumentation is capable of reporting this property, but intentionally does not report it for this element.

Indicates that the element is intentionally stopped.
Aborted (6)
Indicates that the element stopped in an unexpected way.
Dormant (7)

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.
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.
