This article will discuss how to use some cool bandwidth monitoring tools in Linux so that you have a screen that looks like this:

The first thing we will need is a multi-tab flexible terminal emulator. My choice is Tilix, but there are others like Terminator.

sudo apt install tilix -y

Now that you have Tilix, open Tilix, make it full screen.

Divide the screen into four Tilix windows using the menu bar top left to add (+) a vertcal and then two (+) horizontal windows:

Your screen should now look like this:

2021 03 29 06 30

Click in the terminal on the top left, lets install a program called nload.

sudo apt install nload -y

Once installed, clear the screen and run nload.

Use the up and down arrrows to select what interface you wish to monitor. By the way, CTRL-C will stop any of the programs.

I selected my Wi-Fi interface as it was running:

OK, now Click over to the top right terminal.

Let's install a program here called iftop:

sudo apt install iftop -y

Again, clear the screen and run iftop with the following command syntax:

sudo iftop -i wlp7s0

Be sure to replace the "wlp7s0" above with your system's interface name.  Your screen should now look like this:

Perfect - now lets move to the lower right, and we are going to install a program called cbm - color bandwidth meter:

sudo apt install cbm

Clear the screen and run cbm:

sudo cbm

At first it may look like just a black screen. The trick to getting this to fit is to maximize (using the "^" button), then minimize this window (using the diamond button, and it will look perfect:

2021 03 29 06 40

As with nload, you can use your up and down arrows to select/focus on the interface you want to highlight.

We are almost done.

Lastly, move tot he window in the lower left and install bmon:

sudo apt install bmon

Clear the screen and run bmon:


The initial result will look like this:

2021 03 29 06 42

You can enlarge this window to full screen to see details:

2021 03 29 06 44

You can tap "i" or "d" for more information and details within bmon.

Just reduce this window and you are back to all four windows.

You now have a wonderful set of tools to monitor bandwidth!
