1/19 What is the easiest way to figure out how much data is going over
an interface/interfaces to another set_of_interfaces/interface?
(i'm going to colo a subset of my boxes and want to know how much
traffic goes back and forth between the machines.)
\_ Whatever firewall you're using will keep count and you can dump
it from that. Instructions vary by firewall, naturally. If you
just want momentary numbers, trafshow is very handy.
--dbushong
\_ a lot of this traffic now is on the same logical/physical
network so there is no firewalling involved.
\- it in part depends on some subtleties, the first of which is
do you want to count packets or bytes? do you want to distinguish
between vifs or real real interfaces? if WAN, asymetric routing
is a factor. How are you going to count lost packets, retrasmits
etc. if my answers frighten you, perhaps you should cease asking
scary questions. --psb

\_ psb, why don't you ever indent your entries. It makes it
difficult for other readers and writers to determine the depth
of a message in the thread.
\_ The psb shall do as the psb pleases, peon! --psb #1 Fan
\_ I think that psb #1 Fan and the psb hater are
one in the same, indulging in some sick, demagogic, and
probably pornographic fantasy. |
