Applies To: Operations Manager 2007 R2

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

Usage

Use this module to initiate a workflow at the scheduled interval. If you plan to use this module for a simple schedule, consider using the System.SimpleScheduler instead. Do not use this module type from within a discovery workflow. For discovery workflows, use the System.Discovery.Scheduler module type.

Module Type Library Usage

Microsoft.Windows.WmiProvider

Microsoft.Windows.Library

Queries a WMI namespace at a scheduled frequency and returns the results as System.PropertyBagData type data.

System.SimpleScheduler

System.Library

Implements a simple schedule timer that is used as a workflow trigger.

Microsoft.SystemCenter.WSManagement.TimedInvoker

Microsoft.SystemCenter.WSManagement.Library

Calls the WS-Management Invoke operation to run a method on a WS-Management object at a scheduled frequency

Sample

The following XML sample shows a rule that runs on a five-minute schedule and runs a script. The script logs an event to the Operations Manager event log when the script completes.

<Rule ID="Microsoft.Samples.ExecuteTestScript" Enabled="true" Target="Microsoft.Samples.ApplicationX" >
  <Category>Custom</Category>
  <DataSources>
    <DataSource ID="Scheduler" TypeID="System!System.Scheduler">
      <Scheduler>
        <SimpleReccuringSchedule>
          <Interval Unit="Minutes">5</Interval>
        </SimpleReccuringSchedule>
        <ExcludeDates/>
      </Scheduler>
    </DataSource>
  </DataSources>
  <WriteActions>
    <WriteAction ID="Script" TypeID="Windows!Microsoft.Windows.ScriptWriteAction">

      <ScriptBody>
        Option Explicit
        Dim OMAPI
        Set OMAPI = CreateObject("MOM.ScriptAPI")
        Call OMAPI.LogScriptEvent("Microsoft.Samples.LogOpsMgrEvent",101,0,"Script Executed")
