What levels of logging are you familiar with?

Main logging levels commonly used in development and testing:

• TRACE — the most detailed level, used for detailed tracking of program execution.
• DEBUG — for debugging, contains information useful for developers.
• INFO — general information about the application's operation, important events.
• WARN — warnings about potential issues that do not stop the operation.
• ERROR — errors that affect operation but do not lead to a crash.
• FATAL (or CRITICAL) — critical errors that cause the application to stop.

These levels help filter logs by importance and make it easier to analyze system behavior.
