Grafana vs Sentry

# Run Grafana with Docker
docker run -d \
  -p 3000:3000 \
  --name grafana \
  -e GF_SECURITY_ADMIN_PASSWORD=secret \
  grafana/grafana

# Or add to docker-compose.yml
services:
  grafana:
    image: grafana/grafana
    ports: ["3001:3000"]
    volumes:
      - grafana-storage:/var/lib/grafana

# Then: add Prometheus as a data source in the UI

// Next.js — sentry.client.config.js
import * as Sentry from "@sentry/nextjs";

Sentry.init({
  dsn: process.env.NEXT_PUBLIC_SENTRY_DSN,
  tracesSampleRate: 1.0,
});

// Python / FastAPI
import sentry_sdk
sentry_sdk.init(
    dsn=os.environ["SENTRY_DSN"],
    traces_sample_rate=1.0,
)
