A quick guide to getting FastAPI instrumentation up and running with SigNoz — an open-source alternative to Datadog or New Relic — fast.
SigNoz stands as an open-source alternative to Datadog or New Relic. It serves as a comprehensive solution for all your observability requirements, encompassing Application Performance Monitoring (APM), logs, metrics, exceptions, alerts, and dashboards, all enhanced by a robust query builder.
Here is a quick guide to get up and running with FastAPI instrumentation with SigNoz really fast.
I prefer using docker compose.
git clone -b main https://github.com/SigNoz/signoz.git && cd signoz/deploy/
docker compose -f docker/clickhouse-setup/docker-compose.yaml up -dOpen http://localhost:3301. If all went well, you should see a webpage asking you to create an account (yeah, that is correct).
Here is a sample FastAPI app with basic instrumentation. We'll use the same for this example.
git clone https://github.com/SigNoz/sample-fastAPI-app.git
cd sample-fastAPI-app
docker build -t sample-fastapi-app .docker run -d --name fastapi-container \
--net clickhouse-setup_default \
--link clickhouse-setup_otel-collector_1 \
-e OTEL_METRICS_EXPORTER='none' \
-e OTEL_RESOURCE_ATTRIBUTES='service.name=fastapiApp' \
-e OTEL_EXPORTER_OTLP_ENDPOINT='http://clickhouse-setup_otel-collector_1:4317' \
-e OTEL_EXPORTER_OTLP_PROTOCOL=grpc \
-p 5002:5002 sample-fastapi-apppip install locust
locust -f locust.py --headless --users 10 --spawn-rate 1 -H http://localhost:5002Done! Open-source application performance monitoring tools should offer cost efficiency, customization, and transparency. They provide community support, vendor independence, and continuous improvement through collaborative innovation. SigNoz is already very popular with the open-source community — worth watching as it continues to shape the APM landscape.
