log_error and client IP
Hello,
I'm using the following to log error messages from mod_perl to Apache log files :
$r->log_error("mymsg");
It produces the following :
[Sat Dec 24 09:39:43.933388 2016] [:error] [pid 8015] mymsg
I'm a little bit suprised that it does not produce the following :
[Sat Dec 24 09:39:43.933388 2016] [:error] [pid 8015] [client 1.2.3.4:32133] mymsg
Why don't we have the [client] part with the client IP, as for every Apache error message ?
Thank you very much !
Ben

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
[Fri Dec 30 14:36:03 2016] [error] [client 1.2.3.4] user bob not found: /
[Fri Dec 30 14:36:25 2016] [error] [client 1.2.3.4] user alice: authentication failure for "/": Password Mismatch
[Fri Dec 30 13:40:23 2016] [error] [client 1.2.3.4] File does not exist: /var/www/favicon.ico
[Fri Dec 30 00:00:04 2016] [error] [client 1.2.3.4] client sent HTTP/1.1 request without hostname

etc...

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

Not every Apache error message has that; for instance ssl errors in my logs don't have it either :
[Tue Dec 27 20:14:25.730665 2016] [ssl:error] [pid 3243] AH02033: No hostname was provided via SNI for a name based virtual host
you can use :
$r->log_rerror(Apache2::Log::LOG_MARK(), Apache2::Const::LOG_WARNING, APR::Const::ENOTIME, "mymsg");
which outputs :
[Thu Dec 29 17:11:27.040549 2016] [perl:warn] [pid 7811] (20007)No time was provided and one was required.: [client 127.0.0.1:58886] mymsg, referer: http://ppro.libremen.com/
See :
https://perl.apache.org/docs/2.0/api/Apache2/Log.html#C____r_E_gt_log_rerror___
(note : there appears to be a typo in the example, missing parentheses after LOG_MARK)
