The iftop utility looks simple, but this versatile tool can provide a wealth of network monitoring information.
In today's interconnected world, network monitoring has become an essential skill. With the exponential growth of cloud computing, IoT devices, and remote work solutions, understanding network traffic patterns is more critical than ever before. Among the plethora of Linux monitoring tools available, iftop stands out as one of the most powerful and versatile command-line utilities for real-time network bandwidth monitoring. Unlike system monitoring tools like htop or atop that focus on CPU, memory, and process metrics, iftop provides unparalleled visibility into your network traffic patterns, helping you identify bandwidth hogs, troubleshoot performance issues, and optimize your network configuration.
Whether you're managing enterprise servers, optimizing application performance, or simply curious about network activity, mastering iftop will give you valuable insights into your system's network behavior.

What sets iftop apart from basic network monitors is its ability to provide a granular view of network activity at the connection level. Most administrators are familiar with tools that show overall bandwidth consumption, but iftop takes this several steps further by revealing exactly which hosts are communicating and how much bandwidth each connection is consuming.
