To configure logs for stdout aggregation in a Twelve-Factor environment, emit logs as event streams to stdout and stderr. The application must not manage log files or rotation itself, leaving external aggregation to the platform.

Your application should not manage log files internally because Twelve-Factor principles treat logs as event streams. Writing to stdout allows an external aggregator to handle observability, preventing local file rotation issues in distributed systems.

The best way to audit log emission for Twelve-Factor compliance is to verify the application publishes logs to stdout and stderr without embedded rotation logic, ensuring the environment exposes logs directly to an external aggregator.

Yes, you can use this approach for refactoring observability in distributed systems. It verifies that log emission aligns with Twelve-Factor design by streaming events to stdout for external aggregation.

No, Twelve-Factor logging does not require a specific external aggregator. The application simply emits logs to stdout and stderr, allowing any chosen aggregation platform to capture and process the event streams.
