Real-Time Network Statistics with Iftop

Abstract

Monitoring network connections certainly can be frustrating, mainly because they can be established and then disappear within a matter of seconds. In this chapter, I show you how to achieve a Zen-like approach to monitoring network connections on your servers using a command line–based tool called iftop. I then finish by walking through the creation of a configuration file that you can use again on different servers once you have your monitoring set up as you prefer.
