Python Logging Config

A guide to setting up structured, production-grade logging in Python applications using the built-in logging module.

Usage

Ask about logging configuration, handlers, formatters, structured logging, or log aggregation.

Examples

• "Configure dictConfig for a production application"
• "How do I set up JSON structured logging?"
• "Create custom log handlers for different outputs"

Guidelines

• Use logging.getLogger(__name__) for module-level loggers
• Configure logging once at application startup with dictConfig
• Use structured JSON format for machine-parseable logs
• Set appropriate log levels per environment
• Never log sensitive information like passwords or tokens
