CIM_IRQ class
The CIM_IRQ class represents an Intel architecture interrupt request line (IRQ).
Important
The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties
The CIM_IRQ class has these properties.
-
Availability
-
-
Data type: uint16
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.2")
Availability of the IRQ.

-
In Use/Not Available (4)

-
In use and available/sharable
Caption
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64), DisplayName ("Caption")
A short textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
CreationClassName
Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified.
CSCreationClassName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_ComputerSystem.CreationClassName"), CIM_Key, MaxLen (256)
Scoping computer system's creation class name.
CSName
-
Data type: string
-
Access type: Read-only
-
Qualifiers: Propagated ("CIM_ComputerSystem.Name"), CIM_Key, MaxLen (256)
Scoping computer system's name.
Description
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Description")
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"), DisplayName ("Install Date")
Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
IRQNumber
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.1"), key
Part of the object's key value, IRQ number.
Name
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Name")
Label by which the object is known. When subclassed, this property can be overridden to be a key property.
This property is inherited from CIM_ManagedSystemElement.
Shareable
-
Data type: boolean
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.4")
If TRUE, the IRQ can be shared.
Status
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (10), DisplayName ("Status")
String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).
Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.
This property is inherited from CIM_ManagedSystemElement.
Values include the following:
OK ("OK")
Error ("Error")
Degraded ("Degraded")
Unknown ("Unknown")
Pred Fail ("Pred Fail")
Starting ("Starting")
Stopping ("Stopping")
Service ("Service")
Stressed ("Stressed")
NonRecover ("NonRecover")
No Contact ("No Contact")
Lost Comm ("Lost Comm")
TriggerLevel
-
Data type: uint16
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|System Resource IRQ Info|001.3")
Indicates whether the interruption is triggered by the hardware signal going high or low.
Other (1)
Unknown (2)
Active Low (3)
Active High (4)
TriggerType
-
Data type: uint16
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.3", "MIF.DMTF|System Resource IRQ Info|001.2")
Type of interruption that can occur.
Other (1)
Unknown (2)
Level (3)
Edge (4)
Remarks
The CIM_IRQ class is derived from CIM_SystemResource.WMI does not implement this class. See Win32 Classes for classes derived from CIM_IRQ.
