Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Traefik

  • Requires Kubernetes or container knowledge
  • Complex configuration for advanced features

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection
