Analytics and monitoring keep a deployed application observable after release. They combine traffic measurement, log inspection, alerting, and firewall controls to reveal usage, performance, availability, and security problems. section 9.6.3
A practical monitoring setup can include:
- Traffic monitoring with Vercel Analytics for real-time page views, unique visitors, and performance metrics; Google Analytics and Plausible provide broader alternatives. section 9.6.3
- Log management through Vercel’s searchable logs, with New Relic or Datadog available for deeper application analysis. section 9.6.3
- Alerting through services such as PagerDuty or Sentry, which can notify teams about critical problems when platform monitoring lacks alert delivery. section 9.6.3
- Firewall rules that log, deny, challenge, bypass, or rate-limit traffic, configured from the Vercel project dashboard. section 9.6.3
