Hi All,

I can undestand some of them, for ex: my apache server is not running under 80, but under another port 

- how to modify that

- why http://127.0.0.1/ovh-status ??? my installation is not linked with OVH (maybe template solution).

- if i open the script /var/www/mrtg/mrtg-sys/diskrw.pl I can see command : cat /proc/stat | grep disk_io regarding the file /proc/stat, there is nothing inside linked with disk ioM


cat /proc/stat
