How to Tee All Apache Logs To Console

I want to run apache so that all log messages show up on the console (or at least STDERR and/or STDOUT) because something is going wrong that isn't being logged in any file.

I'm currently sifting through an strace service apache2 start but that's a nuclear flyswatter approach to something that should be straight forward.

How can I do it?

The situation in more detail:

Apache responds with a 403 but even after an updatedb doing a locate error.log or locate error_log shows there are no updates to any log files for any virtual host. Nor is there any update to /var/log/apache2/suexec.log.

# apachectl -V
