What is the nginx log format and how can I customize it?

The nginx log format defines how requests are logged. You can customize it using the 'log_format' directive in your nginx configuration.

Can you give me an example of a custom log format?

Sure! A common custom log format might look like this: 'log_format custom_format "$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent"';'

How do I apply this custom format to my access logs?

To apply it, use the 'access_log' directive in your server block: 'access_log /var/log/nginx/access.log custom_format;'

What other variables can I use in the log format?

You can use variables like $remote_addr, $request_time, $upstream_response_time, and many more to capture different data.
