Example of python monitoring network card traffic and drawing using graphite

This article describes how to monitor network card traffic in python and use graphite graphics. For more information, see the following code:

#! /Usr/bin/env python
Import sys, time
From socket import socket
Def read_interface (in_file ):
With file (in_file) as f:
Return f. readlines () [2:]

Return dic

Sys. exit (1)

Print '-' * 80
