Polling network interface octets

[gizmocuz]

Hi, thanks for this project!

To be able to measure the input bandwidth of a network interface we need to do 2 polls and divide this by the poll interval to calculate the bits/seconds (octets needs to be multiplied by 8 for bps)
Would this be possible with this project?

For instance, when you poll each second:

Measurement_1 : 1000
Measurement_2 : 2000

Bandwidth (value) = (Measurement_2 - Measurement_1) / 1 = 1000 bps

When you poll every 10 seconds:

Measurement_1 : 1000
Measurement_2 : 2000

Bandwidth (value) = (Measurement_2 - Measurement_1) / 10 = 100 bps

The better the timer resolution the better (like msec instead of seconds)
