After selecting a single file, clicking the "Tail" link displays a menu allowing you to configure a screen that will show the last lines of that file.
- Enter how many of the file's last lines you wish to view in the "Number of lines" field. If you want the tail screen to automatically refresh while you are viewing it, choose a refresh rate (in seconds) from the drop-down menu. This option can be useful when you wish to view access and error logs as they are being generated.
