  • Article

Applies To: Operations Manager 2007 R2

The Microsoft.SystemCenter.WSManagement.TimedInvoker data source module type calls the WS-Management Invoke operation to run a method on a WS-Management object at a scheduled frequency. This module returns the results of the invocation as Microsoft.SystemCenter.WSManagement.WSManData.

Usage

Use this module to invoke a method on a WS-Management object and return the results at a scheduled frequency from within a workflow.
