Measuring bandwidth utilization for a specific TCP port is possible using custom packet sniffer and flow (NetFlow / sFlow) sensors, providing the respective filtering parameters.

Detailed information is available in the following article: Filter Rules for Custom Packet Sniffing or Netflow Sensors Under PRTG Network Monitor 7

In this particular case one would need to provide filtering parameters for both, TCP and the port in case, as otherwise either all TCP or all port traffic would be displayed.


Protocol[TCP] and (SourcePort[X] or DestinationPort[X])
