Server Load doesn't show up in Admin CP?

The code is there

if ($stats = @exec("uptime")) {
	$datecut=time()-$cookietimeout;
	$guestsarry = $DB_site->query_first("SELECT COUNT(host) AS sessions FROM session WHERE userid=0 AND lastactivity>$datecut");
	$membersarry = $DB_site->query("SELECT DISTINCT userid FROM session WHERE userid<>0 AND lastactivity>$datecut");

	$guests = number_format($guestsarry['sessions']);
	$members = number_format($DB_site->num_rows($membersarry));

	$onlineusers = number_format($guests + $members) . " users online ($members members &amp; $guests guests).";

	preg_match("/averages?: ([0-9\.]+),[\s]+([0-9\.]+),[\s]+([0-9\.]+)/",$stats,$regs);
	echo "<tr class=\"secondalt\"><td>Server Load Averages</td><td><b>$regs[1], $regs[2], $regs[3]</b> $onlineusers</td></tr>\n";
}

except it doesnt show in admin CP (look at attachment). Any way I could fix this??

It only works for *Nix servers (OS X, Linux, Unix). Windows doesn't support the "uptime" command.

Hmm it says server type Linux, or am I just confused? XD

[filburt1]

Stupid question: are you sure it's a Linux server?

[Koutaru]

I'm pretty positive that my site is on a Linux Server (my host is p4host.com)

Your host needs to enable the showing of server loads. Contact your host.

Thank you filburt & Erwin for your help, I'll definately ask
