Hi Peter,
Thx for your answer and its check-list... which helped me to find my mistake and to solve the problem
when you run the agent manually on the affected server, does it return an output /usr/lib/observium_agent/local/apache <<<apache>>> 56775
No.
If not, do you use vhosts ?
Yes
B-) but I had not enabled the default site. As soon as I did, things worked perfectly

If not, do you use vhosts ? does mod_security.conf need updating to allow access from localhost. do you get a perl error on LWP:Simple ?
thanks
