To view bandwidth usage for each of your cPanel accounts:
Log into your WHM
Click “View Bandwidth Usage”, which is under the “Account Information” heading in the left menu
A list of your accounts will be listed, and the bandwidth usage for the current month can be seen under “Xfer (in Megs)”. You can also view usage for other months by clicking the “Last Month” and “Next Month” links.
