Abstract

Methods and apparatus for sampling usage information from a pool of terminals in a data network. A method is provided to perform usage tracking in a data network. The method includes determining a targeted set of terminals from a pool of terminals on the data network, and transmitting tracking parameters to the pool of terminals. The method also includes receiving tracking data from the targeted set of terminals, and mapping the identities of the targeted set of terminals to device log identifiers. The method also includes associating the device log identifiers with the tracking data.
