network programming - Measuring # of dropped packets for individual TCP connections -


i'm interested in measuring network performance. have little tool speed tests , such interested in measuring quality of connection seeing how many packets dropped or re-transmitted.

i know using netstat , such can aggregate numbers, how do individual connections?

  • language: c (not counting on api hey!)
  • os: linux (if there method works mac/win that'd awesome!)

you can use tcpdump , listen specific port, , works wireshark (applying filters specific protocols, ports, network etc )and if not wrong think wireshark use tcpdump on backend.
