The second step is to download "Raw Access" data in group menu "Metric" in cPanel. Click "Raw Access" icon to download and save the file, and double-click the downloaded file to open zip, then open the file with a text reader to find the time when the spike occurred. Usually there will be logs of a specific address in large number of consecutive rows. Make a note of the web address.
