To get an illuminatedcomputing.com nginx access log into CSV format, you can do this:
apache_log_parser -p '%h %{iso}t "%r" %>s %b "%{Referer}i" "%v" "%{User-Agent}i" "%{forwarded_for}t" %T' /var/log/nginx/ic-access.log | vd -f csv
To get the cli command (and various fixes), you have to my git repo (https://github.com/pjungwir/apache-log-parser/) and not upstream. Just say:
python3 -m venv venv source venv/bin/activate pip install -r requirements.txt python setup.py install
