How to Setup Debug Logging in Nginx?
Setting up debug logging in Nginx is relatively simple and straightforward. The first step is to configure the “error_log” directive in the Nginx configuration file. The “error_log” directive allows you to specify the location and name of the debug log file.
The syntax for the “error_log” directive is simple and straightforward. The first parameter is the location of the debug log file. The second parameter is the level of the log messages that will be logged. The higher the level, the more detailed the log messages will be. The levels vary from 0 to 5 with 0 being the least detailed and 5 being the most detailed.
Once the “error_log” directive is configured, Nginx needs to be restarted in order for the changes to take effect. After that is done, the debugging logs will be generated and can be viewed by using a text editor or a logging utility. The logs can then be used to troubleshoot issues and diagnose problems.

Nginx can also log the request details including the URI, headers, cookies, and body of the request. Nginx can also log errors and warnings that may arise from application or system errors.
Nginx is also able to log additional information from custom log formats. This allows you to log information such as user-agent strings, session IDs, referral URLs, and more. Custom log formats can also be used to log data from multiple sources such as the access log, error log, or the application logs.
