Setting level to INFO shows too many logs.

Using plain format for structured analysis.

Setting the level to "ERROR" filters logs to show errors and above. Using "json" format helps structured log analysis.

💡 Hint

Common Mistakes

Using ERROR level hides warnings.

Not including timestamps makes logs less useful.

Setting level to "WARN" shows warnings and errors. "plain" format is readable text. Setting timestamp inclusion to true adds time info to logs.
