CIM_Service class

  • Article

Represents a logical element that contains information to represent and manage the functionality provided by a device or software feature. A service is a general-purpose object to configure and manage the implementation of functionality; it is not the functionality itself.

The following syntax is simplified from MOF code and includes all inherited properties.

This property is inherited from CIM_EnabledLogicalElement.

The possible values are.

Unknown (0)

Indicates that the state of the element is unknown.

Other (1)

Indicates that the state of the element is described in the OtherEnabledState property.

Enabled (2)

Indicates that the element executes or could execute commands, processes any queued commands, and queues new requests.

Disabled (3)

Indicates that the element does not execute commands and that it drops any new requests.

Shutting Down (4)

Indicates that the element is in the process of changing to a Disabled state.

Not Applicable (5)

Indicates the element does not support to be enabled or disabled.

Enabled but Offline (6)

Indicates that the element might be completing commands and that it drops any new requests.

In Test (7)

Indicates that the element is in a test state.

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 the health of its subcomponents.

This property is inherited from CIM_ManagedSystemElement.

Unknown (0)

The implementation cannot report on HealthState at this time.

OK (5)

The element is fully functional and operates within normal operational parameters and without error.

Degraded/Warning (10)

The element is in working order, and 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.

Minor failure (15)

All functionality is available, but some functionality 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 does not work.

Critical failure (25)

The element is nonfunctional, and recovery might not be possible.

Non-recoverable error (30)

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

DMTF Reserved

Reserved.

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, Override ("Name"), MaxLen (256)

A unique identifier of the service that indicates the functionality of the service.

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.

The possible values are.

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.

RequestedState

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

Indicates the last requested state for the element. The current state is indicated by the EnabledState property. This property enables you to compare the last requested and current states.

Note

When the value of the EnabledState property is Not Applicable, this property has no meaning.

This property is inherited from CIM_EnabledLogicalElement.

The possible values are.

Status

Data type: string

Access type: Read-only

Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Indicates the primary status of the object.

Note

This property is deprecated. It is 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")

Indicates descriptions of the corresponding values in the OperationalStatus array. For example, if an element in the OperationalStatus property contains the value Stopping, then the element at the same array index in this property might contain an explanation as to why an object is being stopped.
