For tcmdump or dumpcap, is it possible to have the dropped packets counter statistics during the capture? Currently only available at the end of the capture... How can I know if my capture is missing packets in real-time? Update: I've discovered that pressing CTRL+T (sending SIGINFO according to manpage) during a dumpcap -q capture, displays some info on demand, maybe could add afix to display dropped packets if the info is available: asked 26 Oct '16, 13:56  TomLaBaude edited 31 Oct '16, 14:53 |
One Answer:
As an example: tshark -i 1 -qz icmp,srt This will show # of packets lost and also a % of packet loss. hope this is helpful, John answered 31 Oct '16, 13:06  John_Modlin |
All of this is available at the end of the capture, I was asking for packet drop info during the capture
