API – GetMachineData or GetMachineDataEx

EPM MBSDK SOAP API endpoint (replace localhost with your Core if needed): http://localhost/MBSDKService/MsgSDK.asmx

Table of Contents

ListMachines

Use ListMachines to enumerate devices and retrieve the GUIDs you need for follow-up queries.

Once you have the GUID, use one of the following depending on the data type you need:

GetMachineData — Simple (single-value) fields

&lt;Columns>&lt;Column>Computer."Device Name"&lt;/Column>&lt;Column>Computer.System.Model&lt;/Column>&lt;/Columns>

Script example

$mycreds = Get-Credential -Credential "Leblogosd\david"
$ldWS    = New-WebServiceProxy -uri http://EPM2021/MBSDKService/MsgSDK.asmx?WSDL -Credential $mycreds
$ListDevices = $ldWS.ListMachines("").Devices

# GUID                                   DeviceName      DomainName           LastLogin
foreach ($ListDevice in $ListDevices) {
  $DeviceLDMSName = $ListDevice.DeviceName
  $DeviceLDMSGUID = $ListDevice.GUID

  $GetMachineData = $ldWS.GetMachineData("$DeviceLDMSGUID","&lt;Columns>&lt;Column>Computer.""Device Name""&lt;/Column>&lt;Column>Computer.System.Model&lt;/Column>&lt;/Columns>")
  $device_name  = $GetMachineData.MachineData[0].Value
  $device_Model = $GetMachineData.MachineData[1].Value
  Write-Host "$device_name = $device_Model"
}

GetMachineDataEx — Multi-value (qualified) fields

&lt;Columns>&lt;Column>Computer."Device Name"&lt;/Column>&lt;Column>Computer.Environment.Variable.Value&lt;/Column>&lt;/Columns>

Rule of thumb: if your column set targets a collection or requires a qualifier (e.g., Environment.Variable.Value), use GetMachineDataEx; otherwise, use GetMachineData.
