CIM_ComputerSystem class
A class derived from CIM_System that is a special collection of CIM_ManagedSystemElement instances. This collection provides compute capabilities and serves as aggregation point to associate one or more of the following elements: file system, operating system, processor and memory (volatile and/or non-volatile storage).
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Properties
The CIM_ComputerSystem class has these properties.
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64)
The Caption property is a short textual description (one-line string) of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
CreationClassName
-
The CreationClassName property indicates 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.
-
Description
-
-
Data type: string
-
Access type: Read-only
The Description property provides a textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
InstallDate
-
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")
The InstallDate property is 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
-
The inherited Name property serves as key of a CIM_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 CIM_System keys is required. A heuristic is defined to create the CIM_ComputerSystem name to attempt to always generate the same name, independent of discovery protocol. This prevents inventory and management problems where the same asset or entity is discovered multiple times, but can not be resolved to a single object. Use of the heuristic is optional, but recommended.
The NameFormat property identifies how the computer system name is generated, using a heuristic. The heuristic is outlined, in detail, in the CIM V2 Common Model specification. It assumes that the documented rules are traversed in order, to determine and assign a name. The NameFormat values list defines the precedence order for assigning the computer system name. Several rules do map to the same Value.
Note that the CIM_ComputerSystem Name calculated using the heuristic is the system's key value. Other names can be assigned and used for the CIM_ComputerSystem, that better suit the business, using Aliases.

PrimaryOwnerContact
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (256), MappingStrings ("MIF.DMTF|General Information|001.3")
A string that provides information on how the primary system owner can be reached (e.g. phone number, email address, ...).
This property is inherited from CIM_System.
PrimaryOwnerName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64), MappingStrings ("MIF.DMTF|General Information|001.4")
The name of the primary system owner.
This property is inherited from CIM_System.
Roles
-
Data type: string array
-
Access type: Read-only
A collection of strings that specify the roles this system plays in the IT-environment.
This property is inherited from CIM_System.
Status
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (10)
The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.
This property is inherited from CIM_ManagedSystemElement.
