Shared and Reseller accounts
For Shared and Reseller accounts, users can access their FTP logs via an FTP account created directly by cPanel. By logging into FTP with the username $user_logs (replacing $user with the actual cPanel username) and the cPanel password, users are able to obtain FTP logs from the last time the stat program such as AWStats or Webalizer ran; this will not include the logs from within the last 24 hours.
VPS and Dedicated Server
On a VPS or Dedicated Server, FTP log files are located in the /var/log/messages directory.
