Powershell script  will take the URL parameter from command line and  check Website availability. You should  run powershell script  with these  parameters  set. <OpenMessageInterfaceName>  used  for  HP Operation  Manager. So  you can define  this  parameter as you wish.

#powershell -ExecutionPolicy ByPass -File URL.ps1 <URL>  <OpenMessageInterfaceName>
