i want to test how much data is transfered in wlan - on command line - doable
note: run linux opensuse want to check how healthy is my network connection
can i do this via command line
well we can do the following:
we can think of a couple different things to try, depending on what one wants to know
if we want to monitor how much data is going in/out of a server as it goes about it’s normal business,
then we can run “sar” and check the data for the network devices.
besides this there are also network protocol statistics available as well if they are more interesting.
if we want to know is more about the maximum data transfer rate we can achieve,
then we could just run simple performance tests with “curl” (if we care about HTTP or other protocols it supports)
and we can use the command options that dump out performance stats once the requests are finished.
how to do that - how can we dump out the data on command line!?
How quaint…
Asking how to return raw data results in a console.
I don’t know if anyone has actually <desired> that for a long time because discerning patterns and meaning this way is very difficult.
The gold standard used for many, many years now is mrtg to monitor and analyze network traffic.
Although the standard output is graphed visually, I assume if you <really> wanted to make life difficult for yourself and look only at the raw data you can do so.

Nethogs might be of use to you for this, but you won’t know what transfer
rate you “could” achieve through passive monitoring. What you’re asking
for is something like understanding your bandwidth capabilities the way
you would by using speedtest.net but without running the test (which
consumes bandwidth).
But have a look at nethogs - you might be able to dump the output to see
actual usage statistics from the server.
