Question:
how to display the actual network traffic (wireless) in a terminal?
Additionally: Is it possible to add this info to the chart of top?
Solution:
It’s quite easy! install “iftop” with:
sudo apt-get install iftop
Then run
sudo iftop
from any terminal!
Enjoy!
There is a nice tool called speedometer that displays a graph in the terminal using Unicode block characters, colors, and even adds labels to each peak in the graph.
$ sudo apt-get install speedometer
$ speedometer -l -r wlan0 -t wlan0 -m $(( 1024 * 1024 * 3 / 2 ))
It has several options, can monitor multiple interfaces, can show multiple graphs in several rows or columns, and can even monitor the download speed of a single file (by watching the file size on disk).
