Hello,
yes i checked the php.ini and the open_basedir restriction, but iam not sure with this and therefore i wanted to ask the pros Thx for pointing to this and while i was there i will directly ask what in detail i have to do. in theory i have to add a sumlink to the chroot dir and add the path in /var/www/fcgi/domain/php5/php.ini like this open_basedir = "/var/www/virtual/domain/subdomain:/usr/share/php:/usr/share/rddtool" right?
Sorry i search for rrdtool and i-mscp or cacti or chroot over houres but didnt find any explaining solution. And of course your right whit using monitoring tools on sharedserver / hosting, but perhaps i will only test it befor buy another one ;), but your right.
