For resolved this probleme, i have manuel create this file and when i go in the edit graph a new message has here:

This sound like a problem setting up php support with apache. See e.g. http://docs.cacti.net/?q=node/444

Did you set up the crontab to make cacti poll the devices?

for the crontrab i have put this ligne:

0-59/5 * * * * www-data php4 /usr/share/cacti/poller.php > /dev/null 2>&1

Again, which was the OS? The crontab entry is a bit uncommon to me. The docs look different

my OS is Debian ETCH and my cmplete contrab is:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
