A system may include one or more devices to receive a flow record. The one or more devices may identify a type of the flow record. The one or more devices may parse the flow record for a template identifier (ID) if the type of the flow record is a data record. The one or more devices may further compare the template ID from the data record to a predetermined template ID identifying a data record of template IDs. The one or more devices may identify the data record as a data record of template IDs if the template ID matches the predetermined template ID. The one or more devices may further generate a map associating template IDs, from the data record of template IDs, to template information for decoding and/or interpreting data records. The one or more devices may store the map.
