To monitor your website's bandwidth usage, log in to cPanel and navigate to the Metrics section. There, you'll find a tool labeled Bandwidth, which provides data on the total amount of data transferred to and from your website over a specific period. This includes traffic from web page visits, file downloads/uploads, and, in some cases, email activity.

The Bandwidth tool allows you to track usage patterns, identify periods of high traffic, and monitor for unusual spikes. Regularly reviewing this data can help you manage your resources effectively and avoid exceeding your bandwidth quota, which could lead to additional charges or site downtime.
