Applies To: Operations Manager 2007 R2

The System.Discovery.Scheduler module is a discovery data source module type that outputs System.Discovery.Data data on a scheduled, repeating interval.

Usage

Use this module to initiate a discovery workflow at the scheduled interval. Do not use System.Scheduler in a custom discovery module data source definition.

Parameters

System.Discovery.Scheduler supports the configuration parameter described in the following table.

 

Parameter Type Overrideable Description

Scheduler

PublicSchedulerType

False

Required parameter. Defines the schedule for a workflow.

For information about how to define the Scheduler parameter, see PublicSchedulerType. If you choose a weekly schedule, you must use the same value in the Start and End elements. The PublicSchedulerType schema data type exposes a MultipleDays element. Do not use this element for the System.Scheduler module.

Composition

The System.Discovery.Scheduler module is a composite module, but it does not contain any public member modules.
