Python [Logs]

1. Environment

OTEL_SERVICE_NAME=my-service
OTEL_RESOURCE_ATTRIBUTES=deployment.environment=production
OTEL_EXPORTER_OTLP_ENDPOINT=https://ingest.tracelit.app
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
OTEL_EXPORTER_OTLP_HEADERS=Authorization=Bearer <WORKSPACE_INGEST_KEY>

2. Install

python -m pip install opentelemetry-distro opentelemetry-exporter-otlp
opentelemetry-bootstrap -a install

3. Launch

opentelemetry-instrument <your-start-command>

Examples:

opentelemetry-instrument uvicorn app:app --port 8000
opentelemetry-instrument python manage.py runserver

4. Log libraries

logging
structlog
loguru

Python standard library logging. opentelemetry-bootstrap -a install typically installs opentelemetry-instrumentation-logging. Keep using:

import logging
log = logging.getLogger(__name__)
log.info("order listed", extra={"count": 3})
log.error("payment failed")

Start the process with opentelemetry-instrument ... so the instrumentation is active.

Configure structlog to also emit through stdlib logging (so instrumentation-logging picks them up), or add an OpenTelemetry processor.Minimal pattern: use structlog.stdlib.LoggerFactory and processors that end in Printer / LoggerRenderer bound to stdlib, then:

log = structlog.get_logger()
log.info("order listed", count=3)
log.error("payment failed", err=str(err))

Add a sink that forwards to stdlib logging (recommended with opentelemetry-instrument) or emits OTLP records directly.

from loguru import logger
logger.info("order listed count={}", 3)
logger.error("payment failed: {}", err)

Without a sink/bridge, loguru output stays local and will not appear in Tracelit.

5. Verify

Produce one INFO log and one ERROR log, then confirm both in Tracelit Logs (or the onboarding live preview).
