You can access the website usage statistics (also known as AWStats) by performing these steps:
  1. Go to Data Management > select Reports
  2. Observe the text field containing your username and password near the top of the screen (Typically, the username is "link" and the password will be displayed just below that). This username and password will be required to view your AWStats. 
  3. Click the "+" next to "Site Management Reports"
  4. After ensuring you have found your User Name and Password (See step 2), click the "Web Usage Reports" link and enter your User Name and Password into the login popup.
