On the second step, custom transformation script is executed (if presented). By default, newly created DCI does not have a transformation script. If transformation script is presented, the resulting value of the first step is passed to the transformation script as a parameter; and a result of script execution is a final DCI value. Transformation script gets original value as first argument (available via special variable '''$1'''), and also has two predefined global variables: '''$node''' (reference to current node object), and '''$dci''' (reference to current DCI object). For more information about NetXMS scripting language, please consult [[UM:NetXMS_Scripting_Language_(NXSL)|NetXMS Scripting Language]] chapter in this manual. | On the second step, custom transformation script is executed (if presented).
