from varicon_observability import setup_observability

setup_observability(service_name="varicon-django")

FastAPI (integrations_service)

# integrations_service/main.py
from varicon_observability import setup_observability

setup_observability(service_name="integration-service")

Configuration

Set environment variables:

OTEL_ENABLED=true
OTEL_SERVICE_NAME=my-service
OTEL_EXPORTER_OTLP_ENDPOINT=http://signoz-otel-collector:4318
OTEL_EXPORTER_OTLP_PROTOCOL=grpc  # or http

• Framework logs (Django, FastAPI, Uvicorn, Celery)
• HTTP requests (requests, httpx)
• Database queries (PostgreSQL via psycopg2)
• Redis operations
• Custom traces and metrics
