Server Monitor
<?php
/*
The aim is to create a functional server monitor based on the one
showed on Mark Zuckerberg's monitor on The Social Network movie.
Run so:
php monitor.php
Notes:
- The server LogFormat must be "Common Log Format" (%h %^[%d:%^] "%r" %s %b)
- The server date format must be $d/%b/%Y
