The Get Monitor URL activity has two activity attributes:
Item Attribute--choose the name of the item attribute that you want to use to store the URL for the Workflow Monitor window.
Administration Mode--determine how the URL displays the Workflow Monitor window. If you set Administration Mode to "Yes", the URL displays the Workflow Monitor in 'ADMIN' mode, otherwise it displays the Workflow Monitor in 'USER' mode. See: To Define Activity Attribute Values.
