Members
The CIM_ComputerSystem class has these types of members:
Methods
The CIM_ComputerSystem class has these methods.
| Method | Description |
|---|---|
| RequestStateChange | Requests that the state of the element be changed to the specified value. This method is inherited from CIM_EnabledLogicalElement. |

Properties
The CIM_ComputerSystem class has these properties.
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64)
A short textual description of the object.
This property is inherited from CIM_ManagedElement.
-
-
CreationClassName
-
The name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
This property is inherited from CIM_System.

Dedicated
-
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIB.IETF|MIB-II.sysServices", "FC-GS.INCITS-T11 | Platform | PlatformType"), ArrayType ("Indexed"), ModelCorrespondence ("CIM_ComputerSystem.OtherDedicatedDescriptions")
Whether the computer system is a special-purpose System, that is dedicated to a particular use, rather than being general purpose.
Mobile User Device (17) indicates a dedicated device with limited functionality and programmability such as a barcode scanner that communicates via radio. A hand-held computer would be general purpose not dedicated.

The implementation can not report on HealthState at this time.
OK (5)
The element is fully functional and is operating within normal operational parameters and without error.
Degraded/Warning (10)
The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element may not be operating at optimal performance or it may be reporting recoverable errors.
Minor failure (15)
All functionality is available but some may be degraded.
Major failure (20)
The element is failing. It is possible the some or all of the functionality of this component is degraded or not working.
Critical failure (25)

IdentifyingDescriptions
-
Data type: string array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ComputerSystem.OtherIdentifyingInfo")
An array of free-form strings providing explanations and details behind the entries in the OtherIdentifyingInfo array. Note, each entry of this array is related to the entry in OtherIdentifyingInfo that is located at the same index.
InstallDate
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")
A datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
Name
Serves as key of a System instance in an enterprise environment.
This property is inherited from CIM_System.
NameFormat
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Override ("NameFormat")
The CIM_ComputerSystem object and its derivatives are Top Level Objects of CIM. They provide the scope for numerous components. Having unique System keys is required. The NameFormat property identifies how the Name is generated.

"IP"

OperationalStatus
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")
Indicates the current status of the element. Various operational statuses are defined. Many of the enumeration's values are self- explanatory.
OperationalStatus replaces the Status property 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. Due to the widespread use of the existing Status property in management applications, it is strongly recommended that providers/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 should also provide the primary status of the element since it is single-valued.
Unknown (0)
Other (1)
OK (2)
Degraded (3)
Stressed (4)
The element is functioning, but needs attention. Examples of Stressed states are overload and overheated.
Predictive Failure (5)
The element is functioning nominally but predicting a failure in the near future.
Error (6)
Non-Recoverable Error (7)
Starting (8)
Stopping (9)
Stopped (10)
Implies a clean and orderly stop
In Service (11)
The element is being configured, maintained, cleaned, or otherwise administered.
No Contact (12)
The monitoring system has knowledge of this element, but has never been able to establish communications with it.
Lost Communication (13)
The element is known to exist and has been contacted successfully in the past, but is currently unreachable.
Aborted (14)
Implies an abrupt stop where the element's state and configuration may need to be updated.
Dormant (15)
The element is inactive or quiesced.
Supporting Entity in Error (16)
This element may be OK but 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 (17)
The element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can tell if the complete operation succeeded or not. Completed with Degraded would imply the operation finished, but did not complete OK or report an error.
Power Mode (18)
The element has additional power model information contained in the Associated PowerManagementService association.
