Applies To: Operations Manager 2007 R2

The Microsoft.Windows.Discovery.WMISinglePropertyProvider2 module is a data source module type that queries Windows Management Instrumentation (WMI) for object and single property data at a scheduled, recurring interval and returns the results as System.Discovery.Data type data.

Usage

Use this module only when you are creating a discovery workflow. For more information about Discoveries in management packs, see Discovery.

Sample

The following XML sample shows how you can use the Microsoft.Windows.Discovery.WMISinglePropertyProvider2 module in a Discovery element definition. The class type, ExtendedWindowsServer2008ComputerClassType, is the class type to be discovered. The WMI object will be mapped to this class type. Its property, ServerBootupState, can now be used as criteria for workflows such as rules or monitors.



<ClassType>
  <ClassType ID="ExtendedWindowsServer2008ComputerClassType" Base="WindowsLibrary!Microsoft.Windows.Server.2008.Computer">
    <Property ID="ServerBootupState" Type="string" Key="false" CaseSensitive="false" Length="256" MinLength="0"/>
  </ClassType>
</ClassType>
