Yes you're right, but most or request related errors have this info :
[Fri Dec 30 13:57:16 2016] [error] [client 1.2.3.4] client denied by server configuration: /var/www/robots.txt
[Fri Dec 30 14:09:31 2016] [error] [client 1.2.3.4] script '/var/www/wp-login.php' not found or unable to stat

Thank you very much Vincent !
It works as expected :
[Fri Dec 30 14:32:05.175064 2016] [perl:warn] [pid 48723] [client 127.0.0.1:33045] mymsg

As there is no output example, I did not test more than the first proposed function :
$r->log_error(@message);
My mistake :)

Thank you again Vincent !

Best regards,

Ben
