Hi!
I did following script:

<?php
// Exec a ping
exec('ping -c 5 192.168.236.3',$result);
// Take result from icmp seq = 2
$icmp = strpos($result[2], 'time=');

$icmp = $icmp + 5;

$fin = strpos($result[2], 'ms');
// This is my end
$fin = $fin - $icmp;
// I take only the ms time
$text = substr($result[2],$icmp,$fin);
// Strip whitespace
$ms = trim($text);

if (!is_numeric($ms)) {
$a = 'myemail@host.com';
$asunto = "Servidor Caido";
$mensaje = "Posible caida del servidor. No responde PING.";
mail($a, $asunto, $mensaje);
}

?>

It's very simple, but i think that is working. I will add other options.
