System Center

Updated: August 10, 2011

Applies To: Operations Manager 2007 R2

The Microsoft.Windows.WmiProviderWithClassSnapshotDataMapper module is a data source module type that queries Windows Management Instrumentation (WMI) for object data at a scheduled, recurring interval and returns the discovered class type instance as System.Discovery.Data type data.

Usage

Use this module only when you are creating a discovery workflow and want to discover class type instances. For more information about discoveries in management packs, see Discovery. For more information about relationship types, see ClassType.
