Discover any remaining apache logs - apache2

I am unfamiliar with Apache2 - I want to find out where the logs are going - I have this apache2.conf contents:
ServerName 0.0.0.0
ErrorLog /dev/stderr
TransferLog /dev/stdout
Mutex file:${APACHE_LOCK_DIR} default
PidFile ${APACHE_PID_FILE}
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
HostnameLookups Off
ErrorLog /dev/stderr
LogLevel warn

LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
IncludeOptional conf-available/*.conf
IncludeOptional conf-enabled/*.conf
IncludeOptional sites-enabled/*.conf
and these envvars:
unset HOME
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
SUFFIX=
fi
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid
export APACHE_RUN_DIR=/var/run/apache2$SUFFIX
export APACHE_LOCK_DIR=/var/lock/apache2$SUFFIX
export APACHE_LOG_DIR=/var/log/apache2$SUFFIX
export LANG=C
. /etc/default/locale
export ORACLE_HOME=/usr/lib/oracle/12.2/client64
export LD_LIBRARY_PATH=$ORACLE_HOME/lib/:$LD_LIBRARY_PATH
export NLTK_DATA=/nltk_data
does anyone know if any logs will be populated other than the logs in /var/log/apache2/*?

Answer 1

httpd -V or apache2ctl -V will tell you the log locations in use, there are not more locations other than that.
You should know that:
/dev/stdout is a special path that redirect everything you
write to the standard out of the process
/dev/stderr same as abobe but redirect to standard error of the
process
/dev/null same as abobe but instead of redirect, it just
discards
Extra: The default apache2 logs location is not equal to every O.S. and in some of them envvars file don't exist.
