Hi Luca,
Yes I checked the error log format. Unfortunately, this only applies to log
lines generated by apache and not to the lines created by cgi scripts. The
lines created by a cgi script are just redirected to the httpd-error.log as
they are. For example if you print "test" to stderr in a cgi script, this gets
written just like that to the error log. No vhost information, no timestamp, no
user, just what you printed.
My error log format is:
ErrorLogFormat "%v [%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M%
,\ referer\ %{Referer}i"
But as I said, the ErrorLogFormat is not applied to log lines generated by cgi
scripts.
The apache version I am using is 2.4.25.
Sandro

Hi Sandro,
have you checked https://httpd.apache.org/docs/2.4/mod/core.html#errorlogformat
? What is the current format that you are using? Also, what version of httpd?

Hi suomi,
Thank you for your answer. Unfortunately I am not using php-fpm but fcgid. As
far as I know there is no such possibility in fcgid.
Any other ideas?
Sandro

Hi Sandro
are you using php-fpm as a cgi frontend? If yes: the stdout and stderr
are both redirectet to the php-fpm log (/var/log/php-fpm/*) if you have
in /etc/php-fpm/www.conf:
catch_workers_output = yes
I don't think this will solve all your problems, but it is a good
starting point.
