Introduction to Linux nethogs monitoring tools

Nethogs Introduction

Nethogs is an open-source, free, terminal network traffic monitoring tool that monitors the network traffic of Linux processes or applications. Nethogs can only monitor the network bandwidth consumption of the process in real time. Nethogs supports IPV4 and IPV6 protocols, supports local network cards, and PPP links.

The official introduction is as follows:

Nethogs is a small ' net top ' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools does, it groups bandwidth by process. Nethogs does not rely on a special kernel module to be loaded. If there ' s suddenly a lot of network traffic, you can fire up nethogs and immediately see which PID is causing this. This makes it easy-to-indentify programs that has gone wild and is suddenly taking up your bandwidth.
