Members

The MSFT_MTMemorySummary class has these types of members:

Properties

The MSFT_MTMemorySummary class has these properties.

Available

Data type: uint64

Access type: Read-only

Gets the amount of memory (including Standby and Free memory) that is immediately available for use by processes, drivers, or the operating system.

Cached

Data type: uint64

Access type: Read-only

Gets the amount of memory (including Standby and Modified memory) containing cached data and code for rapid access by processes, drivers, and the operating system.

Capacity

Data type: uint64

Access type: Read-only

Gets the memory capacity on the computer system.

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.

CommitLimit

Data type: uint64

Access type: Read-only

Gets the limit of committed memory on the computer system.

Committed

Data type: uint64

Access type: Read-only

Gets the amount of committed memory on the computer system.

CurrentIndex

Data type: uint16

Access type: Read-only

Gets the current data sample index. Increment at every data sample.

Description

Data type: string

Access type: Read-only

The Description property provides a textual description of the object.

This property is inherited from CIM_ManagedElement.

DynamicMemoryEnabled

Data type: boolean

Access type: Read-only

returns true if dynamic memory is configured on the virtual machine; otherwise, false.

DynamicMemoryMax

Data type: uint64

Access type: Read-only

Gets the maximum amount of memory allowed as dynamic memory on the virtual machine.

ElementName

Data type: string

Access type: Read-only

Gets 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. Note that the Name property of CIM_ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of CIM_LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.

This property is inherited from CIM_ManagedElement.

FormFactor

Data type: uint16

Access type: Read-only

Gets the form factor of memory installed on the computer system. This map is defined in Table 72 in section 7.18.1 (SMBIOS Reference Specification V2.7.0)

Free

Data type: uint64

Access type: Read-only

Gets the free memory that does not contain any valuable data, and that will be used first when processes, drivers or the operating system need more memory.

HardwareReserved

Data type: uint64

Access type: Read-only

Gets the memory that is reserved for use by the BIOS and some drivers for other peripherals.

Installed

Data type: uint64

Access type: Read-only

Gets the memory physically installed on the computer system.

InstanceID

Data type: string

Access type: Read-only

InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: "OrgID:LocalID" Where OrgID and LocalID are separated by a colon (:), and where OrgID must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, OrgID must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between OrgID and LocalID. LocalID is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the OrgID set to "CIM".

This property is inherited from CIM_ManagedElement.

IntervalSeconds

Data type: uint16

Access type: Read-only

Gets the current data collection interval in seconds.

InUse

Data type: uint64

Access type: Read-only

Gets the memory used by processes, drivers, or the operating system.

Modified

Data type: uint64

Access type: Read-only

Gets the memory whose contents must be written to disk before it can be used for another purpose.

Name

Data type: string

Access type: Read-only

Qualifiers: key

Gets the name of memory object.

NonPagedPool

Data type: uint64

Access type: Read-only

Gets the amount of non-paged pool used on the computer system.

PagedPool

Data type: uint64

Access type: Read-only

Gets the amount of paged pool used on the computer system.

PageSize

Data type: uint32

Access type: Read-only

Gets the page size of the operating system.

Speed

Data type: uint32

Access type: Read-only

Gets the speed of memory operating on the computer system, in MHz.

Standby

Data type: uint64

Access type: Read-only

Gets the memory that contains cached data and code that is not actively in use.

Data type: uint64

Access type: Read-only

Gets the total amount of physical memory available to the operating system, device drivers, and processes.
