This article will look at the various options available, to do subscription reporting for Red Hat products. Many large organizations sometimes struggle to keep track of what subscriptions are being used, often maintaining their own spreadsheets. This can be very error prone and time consuming. Systems can even be subscribed to the wrong subscriptions, for example a virtual machine running RHEL using a physical subscription. Many Red Hat customers have several different products, not just RHEL and being able to actively inventory the entire subscription landscape is critical.
