Filtering Results by Interface
To focus on a particular network interface, append the -i option to your command, followed by the interface name you wish to monitor. For instance:

BMON supports output customization through format strings, which include placeholders substituted with real-time values. To display network usage for the eth0 interface in a bespoke format:
bmon -i eth0 -f '%name:%inbytes:%outbytes\n'This command configures the output to show the interface name and the bytes received and sent, with each data point delineated by colons and organized on separate lines.
