What is a key difference between the data captured by NetFlow and data captured by Wireshark?

  • NetFlow provides transaction data whereas Wireshark provides session data.
  • NetFlow data is analyzed by tcpdump whereas Wireshark data is analyzed by nfdump.
  • NetFlow collects metadata from a network flow whereas Wireshark captures full data packets.
  • NetFlow data shows network flow contents whereas Wireshark data shows network flow statistics.

Explanation: Wireshark captures the entire contents of a packet. NetFlow does not. Instead, NetFlow collects metadata, or data about the flow.
