pylogify

PII-safe JSON logging for Python's standard logging module. Every line follows the logify log contract (v1) and carries trace_id / span_id from the active OpenTelemetry span. Emails, card numbers, tokens and other sensitive values are redacted before they are written.

pip install pylogify

The import name is logify:

import logging
from logify import setup_logging

setup_logging()   # once, at startup; routes all loggers (uvicorn, gunicorn, django) to JSON stdout
logging.getLogger(__name__).info("order created", extra={"order_id": "o_1"})
logging.getLogger(__name__).info("user role changed", extra={"log_type": "audit", "actor": {"id": "u_1"}})

For traces and metrics, run the app with opentelemetry-instrument and set OTEL_EXPORTER_OTLP_ENDPOINT. service, env and version default to OTEL_SERVICE_NAME, DEPLOY_ENV and APP_VERSION. The redaction rules are bundled in the package and shared with the Node and Java packages. A field in extra= named like a contract field (level, service, error, ...) is written as extra_<name> so it can't overwrite the contract.
