What would be best to measure bandwidth correctly per domain?
At the moment i have whm and control panel which shows mrtg graph and text data,but whm says it was spended 1000 gb only last month while control panel says how is 6000 gb spended.So something must be wrong since it was never such a big difference between whm and control panel.
Actually i forgot i have nginx for static content where bandwidth is not measured.So now question would be how to reduce overall bandwidth.
regarding measurement "Each cpanel server has a bandwidth monitor located at their main IP with /bandwidth/ on the end. But to get there you have to manually type the URL or paste it into the browser window. This link allows you to load these pages right into WHM for easy access."
You can may be right some scripts that will intimate you as per your requirements.
