Badwidth Monitoring queries - LibreNMS & Smoothwall

[mdrabble]

Our LAN uses Port 4 (ethD) and our External Connection uses Port 6 (ethF)

 

I'm running LibreNMS to monitor bandwidth on port 6 (ethF) and also running the bandwidth graphs via the smoothwall interface on ethF and the figures/graphs do not match in anyway shape or form.

 

On our 300mb connections - smoothwall bandwidth monitor on port 6 (ethF) shows figures/graph within the 300mb limit.

 

On LibreNMS however, when I monitor the same port shows a totally higher bandwidth

 

Any use LibreNMS to monitor bandwidth across their network including their Smoothwall box?

 

Cheers
