Application Logging in Python: Recipes for Observability
Logs are crucial for understanding what's happening inside your application, especially in production, where debugging isn't an option. Along with metrics and traces, effective logging provides a clear picture of issues and behaviour. This article by the dash0 team is a must-read for mastering logging in Python. It covers structured JSON logs, centralised logging config and enriching logs with contextvars and other modern observability practices.
