An example method comprises receiving flow packets from network traffic analyzing platforms, for each particular flow packet: identify the particular flow packet as belonging to one of at least two flow packet types based on a format, if the particular flow packet is sFlow, determine if the particular flow packet is an sFlow sample, counter record, or a third packet type, if the particular flow packet is the sFlow sample or counter record, identify a flow source of the particular flow packet and at least one metric, and update a flow source data structure else ignore the particular flow packet, and if the particular flow packet is a second flow packet type: if the particular flow packet is of a format that matches a template, identify the flow source, and update the flow source data structure to include the identified flow source and the at least one metric.
