I am using Ubuntu.

I need to count the number of packet received in a specific interface. I found this can be done using netstat. However, I need to count starting from t=zero until a specific time I want (t=...) and the counter shall be start from zero

This can be done if everytime I restart the computer so the counter starts from zero, but I just want to know if there is any other solution to capture how many packets on a specific interface within a certain time I want.

  • Interface stats are available via SNMP. – Zoredache Jan 30 '12 at 18:13
  • @zoredache : yes, and also in other tools that basically take the stat from /proc/sys.. but i am curious how to make the packet counter to 0, without having to restart the machine all the time – sateayam Jan 30 '12 at 18:37

use nstat(coming from iproute2 instead of deprecated net-tools) instead, ref https://superuser.com/questions/1590901/reset-netstat-statistics

I am afraid there is no way to reset counters without restarting ( or unload-load cycle nic card module if nic is loaded via dynamic module.)

Virtual zero-ing concept is discussed here though.
