<br></b><br><br><br>I can undestand some of them, for ex: my apache server is not running under 80, but under another port
<br>- how to modify that
<br>- why <a href="http://127.0.0.1/ovh-status" target="_top" rel="nofollow">http://127.0.0.1/ovh-status</a> ??? my installation is not linked with OVH (maybe template solution).
<br>- if i open the script /var/www/mrtg/mrtg-sys/diskrw.pl I can see command : <b>cat /proc/stat | grep disk_io</b> regarding the file /proc/stat, there is nothing inside linked with disk ioM
<br><br><b>cat /proc/stat</b><br><b><br>cpu 489557 34610 291223 33836777 591595 6156 17548 0 0
