Identity

Optional

Microsoft.SharePoint.PowerShell.SPUsageServicePipeBind

Specifies the usage service to get. If the Identity parameter is not specified, the cmdlet returns the local usage service.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a usage service (for example, UsageService1); or an instance of a valid SPUsageService object.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

Note:
When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.
