Next.js Server Monitoring with Auto-Repair

TL;DR

Keep self-hosted Next.js alive — PM2/cluster health, Node memory leaks, nginx 502s, and deploy regressions with automated repair.

Key facts

Framework
Nextjs

Self-hosted Next.js is ops-heavy

Teams leave Vercel when bills climb, then discover PM2 restarts are not a strategy. Reflex monitors Node processes, reverse proxies, and deploy markers so you catch memory leaks and stuck builds before users tweet about downtime.

Signals that matter

  • Node event-loop latency and RSS growth
  • PM2 restart storms
  • nginx upstream timeouts to the Node port
  • Disk pressure from .next caches and logs
