CIM_LogicalElement class

CIM_LogicalElement is a base class for all the components of a System that represent abstract system components, such as Files, Processes, or LogicalDevices.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Members

The CIM_LogicalElement class has these types of members:

• Properties

Properties

The CIM_LogicalElement 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.

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.

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.

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: MaxLen (1024)

The Name property defines 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 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.

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.

("OK")

("Error")

("Degraded")

("Unknown")

("Pred Fail")

("Starting")

("Stopping")

("Service")

("Stressed")

("NonRecover")

("No Contact")

("Lost Comm")

("Stopped")

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.
