I don't have any Python or Django experience but I'd assume you can make a system call like tail in Python and relay the details.

From there, I'd use a jQuery .ajax() call with a javascript setInterval() loop to your Python script and output the results to a div on the web page. Overall a pretty simple solution.

In this instance, you really wouldn't need to use an open tail -f system call because the nature of the JS setInterval() method, the Python script will be called over and over again until the JS clearInterval() method is called. You'll aggregate your script details in either Python or JS depending where you want to do the work. I'd suggestion Python since you'd have more robust features at your fingertips and you would send less data via the AJAX call. Theoretically, there probably shouldn't be too much logic needed in the jQuery code on the front end. Just display the data.
