A very long time ago, back in the days that I was a Network Support Officer in a College. I created a small PHP page to parse MRTG files and display a nice index page.
Considering how long ago it actually was now, I’m pretty certain it wouldn’t work anymore.
Demo (Almost, no actual files for it to parse lol)
