LARTC - Jul 2003 - Difference between tc reported rate and IPTraf Rate

I am using HTB+IMQ on an Ethernet bridge and tc for statistics reporting.

I am finding that tc reported rate is about 5-10% less than that reported by
IPTraf for the same traffic.

Has anyone observed this before? Which is more accurate?

Rajesh

Hey pal,

 What about the overhead part to create the display that flows between
the internet gateway(Machine you are monitoring) and your machine???.

[LARTC] Difference between tc reported rate and IPTraf RateTrevor,

Thanks for pointing out one of the possible reasons for the difference.

However, in this case I have also tried using the local display and got similar
results ( though the difference reduces a bit).

Thanks,

Rajesh
