Thank you for the answer.

The challenge is that in Debian hostname should only be the name and not 
the FQDN.

When I set the hostname to FQDN, Nginx do log with the FQDN, but this 
break other things that relay on hostname only be name and not FQDN.

If it's not possible to configure this in Nginx I would need to find a 
One way could be to make Nginx log to file and rsyslog read that file.

Is that my only way?
