VBScript Example

The following example shows how to retrieve a list of Exchange_Logon instances, and how to retrieve the associated StreamOperationRate properties.

' Purpose:   Display each Exchange_Logon found for Exchange server,
'            and show the StreamOperationRate property on the Exchange_Logon
'            objects
' Change:    cComputerName [string] the computer to access
' Output:    Displays the name of each Exchange_Logon and StreamOperationRate property

On Error Resume Next
Dim cComputerName
Const cWMINameSpace = "root/MicrosoftExchangeV2"
Const cWMIInstance = "Exchange_Logon"
cComputerName = "MyComputerNETBIOSName"

Dim strWinMgmts		' Connection string for WMI
Dim objWMIExchange	' Exchange Namespace WMI object
Dim listExchange_Logons	' ExchangeLogons collection
Dim objExchange_Logon		' A single ExchangeLogon WMI object

' Create the object string, indicating WMI (winmgmts), using the
' current user credentials (impersonationLevel=impersonate),
' on the computer specified in the constant cComputerName, and
' using the CIM namespace for the Exchange provider.
strWinMgmts = "winmgmts:{impersonationLevel=impersonate}!//"& _
Set objWMIExchange =  GetObject(strWinMgmts)
' Verify we were able to correctly set the object.
If Err.Number <> 0 Then
  WScript.Echo "ERROR: Unable to connect to the WMI namespace."
  ' The Resources that currently exist appear as a list of
  ' Exchange_Logon instances in the Exchange namespace.
  Set listExchange_Logons = objWMIExchange.InstancesOf(cWMIInstance)
  ' Were any Exchange_Logon Instances returned?
  If (listExchange_Logons.count > 0) Then
    ' If yes, do the following:
    ' Iterate through the list of Exchange_Logon objects.
    For Each objExchange_Logon in listExchange_Logons
       ' Display the value of the StreamOperationRate property.
       WScript.echo "StreamOperationRate      = "& _
        " ["&TypeName(objExchange_Logon.StreamOperationRate)&"] "& _
    ' If no Exchange_Logon instances were returned,
    ' display that.
    WScript.Echo "WARNING: No Exchange_Logon instances were returned."
  End If
