I need to measure network usage on a specific interface during a specific time. I'm doing some experiments on an application so I need to know how much data is being passed around on a specific interface. So things go like:
1- start recording network usage
2- start the program
3- end the program
4- stop recording network usage
I know tools like vnstat and nload exist, but they don't seem to have the feature I need

Does it matter which application the traffic comes from? If not, there's a plaintext table maintained by the kernel at/proc/net/devwith network stats for each interface including bytes received and transmitted.

vnstat -l does do what you need
Simply open a terminal window and type vnstat -l. Then start your program that consumes network bandwidth. When your program ends return to the terminal window and press Ctrl+C. The terminal will then show time elapsed and network traffic consumed:
$ vnstat -l
Monitoring enp59s0... (press CTRL-C to stop)
rx: 1.74 Mbit/s 149 p/s tx: 32 kbit/s 62 p/s^C
enp59s0 / traffic statistics
rx | tx

Thank you so much. Somehow I managed to miss this, just how I can log it into a file and stop it if I'm doing this in a script? (other than killing it)

@Manuel If you are calling it in a script then you would usevnstat -q > starttotalat start of your script. Do your processing then usevnstat -q > endtotal. Then parse the two output files to calculateendtotal-starttotal=bytesused.

vnstat -q > starttotal at start of your script. Do your processing then use vnstat -q > endtotal. Then parse the two output files to calculate endtotal - starttotal = bytesused.– WinEunuuchs2Unix
