How to use bmon to monitor network bandwidth on Linux – Guide
Bmon is a network monitoring and debugging tool for Unix-like systems. It collects network-related statistics and displays them visually in a user-friendly format. It is reliable and effective, and can read input with a variety of input modules. It presents output in a variety of output modes, including an interactive curses user interface as well as programmable text output for scripting purposes. Almost all Linux distributions have the bmon package in their default repositories, so it can be easily installed using the default package manager. However, the available version may be a little older. ..
We discussed running an internet speed test from the Linux command line. This is great for testing your internet speed. But what if you want to monitor the bandwidth usage of an internal connection? Enter bmon, a lightweight, real-time command-line bandwidth monitoring tool. The bmon utility is a tool that provides information about network interface usage on the command line, but in a very familiar way. Bmon stands for “butterfly” and it’s a powerful CLI-based network bandwidth monitoring and debugging tool for Unix/Linux systems to collect network related statistics and present them visually on the command line in a user-friendly way. It logs traffic usage on all network interfaces in the system. It is an effective and fast real-time network bandwidth monitor and rate estimator.

Running bmon to capture live bandwidth usage
bmon -f This will start the bmon tool and display all the active processes on your system.
Set the specific interface to display:
The -p flag can be used to set the policy defining which network interfaces to display as below. By default, all network interfaces are displayed. The -p flag can be used to set the policy defining which network interfaces to display as below. By default, all network interfaces are displayed. ..
grep -b ‘^(?:.*)$’ /proc/sys/kernel/vm/drop_caches This will print out the number of bytes and bits per second that the kernel is dropping caches.
