Monitoring the load on your server is very important and sometimes vital. To do this very quick and easy on your linux server requires 1 line of code to get.

<?php
$load = explode(" ", exec("cat /proc/loadavg"));
echo 'Server Load: '.$load[0].'%&nbsp;&nbsp;'.$load[1].'%&nbsp;&nbsp;'.$load[2].'%';
?>

The above code will output something similar to: Server Load: 0.01% 0.02% 0.00%

**NOTE: Your server must allow you to run the exec() php command. Some hosts disable the execution of this and several other php functions.
