This code is leftover from m0n0wall. Not sure if its accurate since
we now factor swap into the equation.
At any rate, here is the code in question:
exec("/sbin/sysctl -n vm.stats.vm.v_active_count
vm.stats.vm.v_inactive_count " .
"vm.stats.vm.v_wire_count vm.stats.vm.v_cache_count
vm.stats.vm.v_free_count", $memory);
$totalMem = $memory[0] + $memory[1] + $memory[2] + $memory[3] +
$memory[4];
$freeMem = $memory[4];
$usedMem = $totalMem - $freeMem;
$memUsage = round(($usedMem * 100) / $totalMem, 0);
return $memUsage;
If someone wants to perfect it, please do and I'll commit.
