The Subscription Logger (Sublogger) class leverages the Azure REST API to fetch subscription ID, subscription name, compute core, hosted service and storage account information for a  predefined list of subscriptions contained in a separate XML document.

Once the REST call returns a web response, it is converted to XML at runtime and parsed using XParse, then the relevant data is logged to a SQL database by triggering a stored procedure.
