This will be one of a few posts where I work on building an app that will visualize traffic to a web server, letting me monitor it as its being used. I plan to use App Designer, then deploy the app to the web, which was a new feature in R2018a. But before I do that, I need to figure out how to read the log files, and do it continuously as they get updated during the day.

Features covered in this code-along style video include:

• textscan, fopen, fseek, and ftell
• datetime functions
