Proper logging is critical for production debugging. I configure loggers for different apps and libraries. I use file handlers for persistence and console handlers for development. Log rotation prevents disk fill-up. I set appropriate levels (DEBUG, INFO, WARNING, ERROR, CRITICAL) per environment. Structured logging with JSON formatters enables log aggregation. I log exceptions with logger.exception() to capture tracebacks. For sensitive data, I filter logs to prevent credential leaks. This provides visibility into application health and user issues.
