What are the different logger levels in logging frameworks?

Logging frameworks typically have several levels, including DEBUG, INFO, WARN, ERROR, and FATAL. Each level indicates the severity of the log message.

Can you explain what each level means?

Sure! DEBUG is for detailed information, INFO is for general events, WARN indicates potential issues, ERROR is for error events that might allow the application to continue running, and FATAL is for very severe error events that will presumably lead the application to abort.

When should I use WARN instead of ERROR?

Use WARN when you want to indicate a potential problem that doesn't stop the application from functioning, while ERROR should be used for actual issues that need immediate attention.

Are there any best practices for using these logging levels?

Yes, it's best to use the appropriate level for the message's severity, avoid excessive logging at DEBUG in production, and ensure that sensitive information is not logged.
