Wusste nich wo ich es reinpacken sollte also ma hier.
Hab hier n paar Scripts die root - vServer User interessieren Sollten.
Mit diesen Scripts kannst du deine Server Auslastung auslesen und auf ner Webseite anzeigen lassen.
CPU - Auslastung Auslesen.

Teil 2 Datei showload.php
PHP Code:
<pre>
<?php
require_once("class_CPULoad.php");
$cpuload = new CPULoad();
$cpuload->get_load();
$cpuload->print_load();
?>
</pre>
Das Script dann mit deine-domain.de/showload.php aufrufen
