Example

The following example returns the state of every worker process in each application pool on a server.

' Connect to the WMI WebAdministration namespace.  
Set oWebAdmin = GetObject("winmgmts:root\WebAdministration")  
  
' Return all application pools that are present on the server.  
Set colAppPools = oWebAdmin.ExecQuery("SELECT * FROM ApplicationPool")  
  
' Return each application pool name.  
For Each oAppPool In colAppPools  
    WScript.Echo oAppPool.Name  
    WScript.Echo String(Len(oAppPool.Name), "-")  
  
    ' Get all worker processes in the application pool.  
    Set oWorkerProcesses = _  
        oAppPool.Associators_("ApplicationPoolContainsProcess")  
  
    ' Return each worker process ID and report its state by using  
    ' the GetStateDescription helper function.  
    For Each oWorkerProcess In oWorkerProcesses  
        WScript.Echo "Process ID " & oWorkerProcess.ID & _  
            " is " & GetStateDescription(oWorkerProcess.GetState) & "."  
    Next  
    WScript.Echo  
Next  
  
' Return the text string that corresponds to the state code.  
Function GetStateDescription(StateCode)  
    Select Case StateCode  
        Case 0  
            GetStateDescription = "starting"  
        Case 1  
            GetStateDescription = "running"  
        Case 2  
            GetStateDescription = "stopping"  
        Case 3  
            GetStateDescription = "unknown"  
        Case Else  
            GetStateDescription = _  
                "Attempt to retrieve worker process state failed."  
    End Select  
End Function  

Because WorkerProcess is a transient object, the state reported by WMI when the script is run may no longer be valid after some time has elapsed.
