Das Modul mod_status bietet einen Handler, der Informationen zur aktuellen Auslastung des
Servers anbietet. Dieser kann über eine "Directory" oder "Location" Direktive
an eine URL
gebunden und von außen abgefragt werden. Der Zugriff sollte aber immer eingeschränkt
werden. Ein Beispiel für die Einbindung des Handlers:
<Location /server-status>
SetHandler
server-status
Order
deny,allow
Deny
from all
Allow
from localhost
</Location>
Mit Hilfe der Anweisung
ExtendedStatus
On
wird der Output noch umfangreicher:
