While ‘iftop’ is user-friendly enough for beginners, it also offers advanced functionalities for power users aiming for deeper insights into their traffic patterns. Here are some features you can leverage:

Saving and Logging Results

If you need to maintain logs of your traffic data, ‘iftop’ provides options to export the data for offline analysis. You can redirect the output to a text file or a structured log format for even greater insights.

For comprehensive data logs, consider integrating ‘iftop’ through scripts with other Linux tools like `grep`, `awk`, or `sed` to manipulate the data as needed. This combination can yield powerful results, especially when managing complex scalable hosting environments.
