Hi..
Please look attachments first. Flow monitor is showing wrong http Bandwidth in in chart/Tabular. You can see in attachment on dashboard asg is showing approx 450kbps, firefox is showing 69KB=500+kbps approx, a third party download meter is showing 500+kbps, but flow monitor is showing 119 KB/s it mean 119x8=900kbpa approx. Its a huge difference.
But look at second attachment that is FTP download, flow monitor is showing 100% correct bandwidth.
