loki-sdk
Loki-compatible logging SDK. Plain key=value wire format, per-service typed schemas, async-safe context propagation, auto-injected exception summary. Built on stdlib logging — no structlog/loguru.
Install
pip install loki-sdk
Usage
import logging
from loki_sdk import FieldSpec, LogSchema, LoggingConfig, bound, configure
SCHEMA = LogSchema(
service_name="my-service",
fields=(FieldSpec("status_code"), FieldSpec("duration_ms")),
)
configure(LoggingConfig.from_env(SCHEMA))
logger = logging.getLogger(__name__)
with bound(request_id="abc-123", endpoint="POST /clean-text"):
logger.info("request_completed", extra={"status_code": 200, "duration_ms": 12.4})
Output:
2026-04-29T10:00:00Z [INFO] [my-service] [POST /clean-text] request_completed | status_code=200 duration_ms=12.4 request_id=abc-123
On exceptions, error="ClassName: msg" and caller=<module>:<func>:<lineno> are injected automatically.
