Generally speaking, systems, methods and media for managing an application usage metering system are disclosed. Embodiments of the method may include initiating discovery agents for one or more server resources and interrogating by the discovery agents the one or more server resources to discover a plurality of discrete server processes and associated discovery data for each process. Embodiments may also include collecting discovery data for the discovered discrete server processes in a centralized repository and mapping one or more of the processes to an application and a customer based on the collected discovery data. Further embodiments may also include performing an administrative function based on the mapped discrete server processes, such as generating a customer bill, generating a report based on the mapped discrete server processes, assigning a customer to a process, or changing a status of a discrete server process.
