Abstract: An event logging system is provided for an interactive entertainment network system having a headend or content provider interconnected via a distribution network to multiple user interface units. Each user interface unit has an event evaluator to determine whether an event is a loggable event. The user interface unit can be dynamically reconfigured to choose different groupings of events for logging. Loggable events are reported to an event log manager at the headend over the distribution network. The event logging system is designed so that the user interface unit does not need to know the exact location of the event log manager at the headend. The event log manager selects an appropriate database to store event information pertaining to the reported event. The database selection is based upon the kind of event being logged. The database might be local at the headend or remote therefrom.
