The Apache access logs are not written by default. The content of the Apache log messages is redundant because the same information can be attained within the Airlock log system. On high load environments writing Apache log files may harm the performance and waste disk space.
To enable the Apache access logs, do the following steps:
# vi /opt/airlock/custom-settings/ext-apache/env.sh
DO_LOG_ACCESS=TRUE
# systemctl restart airlock-ext-apache
# sh /opt/airlock/ext-apache/etc/write-access-logs.sh
# ls -al /home/log/access-logs/
