Monitoring & Error Tracking in Production
Keep your deployed Next.js app healthy with structured logging, error tracking via Sentry, performance analytics, and uptime monitoring.
Why Monitor Production?
Once your app is live, you cannot reproduce every user's environment. Monitoring tells you when something breaks, how often, and for whom — so you fix issues before they spread.
The Three Pillars
Observability rests on:
- Logs: discrete events
- Metrics: numbers over time (latency, error rate)
- Traces: the path of a request across services
