Methods and systems for defining and distributing network data collection rule sets and for filtering messages using the rule sets are disclosed. Message-based filter criteria are automatically deduced from CDR-based filter criteria and downloaded to site collectors. The site collectors implement rule changes on-the-fly using a table-driven system. The message-based rule sets downloaded to the site collectors are supersets of the messages required by multiple different network monitoring applications. As a result, non-redundant, multi-application data streams are sent across the service provider's internal network, resulting in efficient bandwidth utilization.
