How to change the nginx log format?

Answer:

Firstly, you need to define a valid log format for nginx, e.g.

log_format foo '$remote_addr - $remote_user [$time_local]  '
                '"$request" $status $bytes_sent '
                '"$http_referer" "$http_user_agent"';

Then, you need to link that format with your log file:

access_log /var/logs/nginx-test-access.log foo;
