how can I print this information from the command line
tx/rx Bytes
and is it possible to get to this information using API?
I would like to check and store the values in the database.

Of course, if for this you can use the command-traffic monitor your EoIP or any interface.
interface monitor-traffic eoip-tunnel_1_5 interval=2s (1s, 3s etc)
As for the API Similarly, all depends what values you want to store and every time, you could retrieve all values and before storing your DB values need to cut and store, with a statement of its programming language, or directly in the database with some stored procedure.
Apologies for my writing I am using a translator. ![]()

I have the very same question as mysz0n.
Unfortunately, the command
/interface monitor-traffic <interface>
just shows realtime data, whereas Winbox is able to show the total rx/tx bytes (since last reboot, or so).
How to get this info on CLI?
EDIT:
I found the command:
/interface print stats
