Child Loggers
Learn how to create and use child loggers in the Python SDK.
Child loggers allow you to create new logger instances that inherit the configuration of the parent logger, but with additional default metadata.
from vedatrace import VedaTrace
parent = VedaTrace("YOUR_API_KEY", service="your-service")
api_logger = parent.child({"module": "api"})
api_logger.info("Request handled", {"request_id": "123"})Metadata Precedence
When using child loggers, metadata is combined with the following precedence (from lowest to highest):
- Parent logger's default metadata
- Child logger's default metadata
- Per-call metadata
Child loggers share the same runtime engine (transports, batching buffer, etc.) as the parent logger. child.close() does not tear down the parent-owned engine.
