Is there an opportunity to write the log messages of apache (V2.4) to the journalctl/journald logs instead to log to a file?
(I've seen Apache2.5 will have a mod_journald to allow this task)
Could set a custom log in your httpd.conf.
CustomLog "|/bin/logger -t access_log -p user.info" <log-formatters>
See the Apache docs for the formatting variables.
