Properties

The MSFTSM_System 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_ManagedElement.

CreationClassName
Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256)

CreationClassName 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

Contains a textual description of the object.

This property is inherited from CIM_ManagedElement.

ElementName
Data type: string
Access type: Read-only

Contains a user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

This property is inherited from CIM_ManagedElement.

EnabledDefault
Data type: uint16
Access type: Read/write

An enumerated value indicating an administrator's default or startup configuration for the Enabled State of an element. By default, the element is "Enabled" (value=2).

This property is inherited from CIM_EnabledLogicalElement.

Enabled (2)

Disabled (3)

Not Applicable (5)

EnabledState
Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.OtherEnabledState")

EnabledState is an integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled. The following text briefly summarizes the various enabled and disabled states: Enabled (2) indicates that the element is or could be executing commands, will process any queued commands, and queues new requests. Disabled (3) indicates that the element will not execute commands and will drop any new requests. Shutting Down (4) indicates that the element is in the process of going to a Disabled state. Not Applicable (5) indicates the element does not support being enabled or disabled. Enabled but Offline (6) indicates that the element might be completing commands, and will drop any new requests. Test (7) indicates that the element is in a test state. Deferred (8) indicates that the element might be completing commands, but will queue any new requests. Quiesce (9) indicates that the element is enabled but in a restricted mode. Starting (10) indicates that the element is in the process of going to an Enabled state. New requests are queued.

This property is inherited from CIM_EnabledLogicalElement.

HealthState
Data type: uint16
Access type: Read-only

Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its sub-components.

This property is inherited from CIM_ManagedSystemElement.

The following values have been defined:

Unknown (0)

The implementation cannot 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 might not be operating at optimal performance or it might be reporting recoverable errors

Minor failure (15)

All functionality is available but some might be degraded.

Major failure (20)

The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.

Critical failure (25)

The element is non-functional and recovery might not be possible.

Non-recoverable error (30)

The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost.

DMTF Reserved

DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.

IdentifyingDescriptions
Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_System.OtherIdentifyingInfo")

An array of free-form strings providing explanations and details behind the entries in the OtherIdentifying Info array. Note, each entry of this array is related to the entry in OtherIdentifyingInfo that is located at the same index.

This property is inherited from CIM_System.

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.

Name
Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256)

The inherited Name serves as the 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: MaxLen (64)

The System object and its derivatives are top-level objects of CIM. They provide the scope for numerous components. Having unique System keys is required. A heuristic can be defined in individual System subclasses to attempt to always generate the same System Name Key. The NameFormat property identifies how the System name was generated, using the heuristic of the subclass.

This property is inherited from CIM_System.

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 OperationalStatus should contain the primary status for the element.

Note  OperationalStatus replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, Microsoft strongly recommends that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.
 

This property is inherited from CIM_ManagedSystemElement.

The following values have been defined:

Unknown (0)

Indicates the implementation cannot report on OperationalStatus at this time.

Other (1)

Indicates an undefined state.

OK (2)

Indicates full functionality without errors.

Degraded (3)

Indicates the element is working and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors

Stressed (4)

Indicates that the element is functioning, but needs attention. Overload and overheated are examples of Stressed states.

Predictive Failure (5)

Indicates that an element is functioning nominally but predicting a failure in the near future.

Error (6)

Indicates that an error has occurred.

Non-Recoverable Error (7)

A non-recoverable error has occurred.

Starting (8)

The job is starting.

Stopping (9)

The job is stopping.

Stopped (10)

The element has been intentionally stopped.

In Service (11)

Indicates the element is being configured, maintained, cleaned, or otherwise administered.

No Contact (12)

Indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.

Lost Communication (13)

Indicates that the job is known to exist and has been contacted successfully in the past, but is currently unreachable.

Aborted (14)

Indicates the job stopped in an unexpected way. The state and configuration of the job might need to be updated.

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 may be OK but is unable to 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, ErrorError, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error).

Power Mode (18)

"Power Mode" indicates that the element has additional power model information contained in the associated PowerManagementService association.

DMTF Reserved

DMTF has reserved this portion of the range for additional OperationalStatus values in the future.

Vendor Reserved

Microsoft has reserved the unused portion of the range for additional OperationalStatus values in the future.

OtherEnabledState
Data type: string
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1.

This property is inherited from CIM_EnabledLogicalElement.

OtherIdentifyingInfo
Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), MaxLen (256), ModelCorrespondence ("CIM_System.IdentifyingDescriptions")

OtherIdentifyingInfo captures additional data, beyond System Name information, that could be used to identify a ComputerSystem. One example would be to hold the Fibre Channel World-Wide Name (WWN) of a node. Note that if only the Fibre Channel name is available and is unique (able to be used as the System key), then this property would be NULL and the WWN would become the System key, its data placed in the Name property.

This property is inherited from CIM_System.

PrimaryOwnerContact
Data type: string
Access type: Read/write
Qualifiers: MaxLen (256), MappingStrings ("MIF.DMTF|General Information|001.4")

A string that provides information on how the primary system owner can be reached (for example, phone number, e-mail address, and so on).

This property is inherited from CIM_System.

PrimaryOwnerName
Data type: string
Access type: Read/write
Qualifiers: MaxLen (64), MappingStrings ("MIF.DMTF|General Information|001.3")

The name of the primary system owner. The system owner is the primary user of the system.

This property is inherited from CIM_System.

RequestedState
Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

RequestedState is an integer enumeration that indicates the last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. By default, the RequestedState of the element is 5 ("No Change"). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. Offline (6) indicates that the element has been requested to transition to the Enabled but Offline EnabledState. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. A particular instance of EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ("Not Applicable") is used.

This property is inherited from CIM_EnabledLogicalElement.

Roles
Data type: string array
Access type: Read/write

An array (bag) of strings that specifies the administrator -defined roles this System plays in the managed environment. Examples might be 'Building 8 print server' or 'Boise user directories'. A single system may perform multiple roles. Note that the instrumentation view of the 'roles' of a System is defined by instantiating a specific subclass of System, or by properties in a subclass, or both. For example, the purpose of a ComputerSystem is defined using the Dedicated and OtherDedicatedDescription properties.

This property is inherited from CIM_System.

Status
Data type: string
Access type: Read-only
Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Contains a string indicating the primary status of the object.

Note  This property is deprecated and replaced by the OperationalStatus property. If you choose to use the Status property for backward compatibility it should be secondary to the OperationalStatus property.
 

This property is inherited from CIM_ManagedSystemElement.

StatusDescriptions
Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.OperationalStatus")

Contains strings describing the corresponding values in the OperationalStatus array. For example, if an element in OperationalStatus contains the value Stopping, then the element at the same array index in this property may contain an explanation as to why an object is being stopped.

This property is inherited from CIM_ManagedSystemElement.

TimeOfLastStateChange
Data type: datetime
Access type: Read-only

The date or time when the EnabledState of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated.

This property is inherited from CIM_EnabledLogicalElement.
