Presentation

Thoses scripts and templates will allow you to create statistics for wifi interfaces on a Linux host. Only wifi specifics parameters will be graphed as traffic can be done by others methods. You will be able to see :

• Connection bit rate (Mb/s)
• Quality of the link (%)
• Signal and Noise level (dBm)

The values are gather from output of iwconfig command. Listing of interfaces is from /proc/net/wireless pseudo file.

This is my first attempt to create some templates for Cacti. So use it at your own risks :)
Please report every bug, problems or patchs.
