The short version

  • Each has a real cost: Chef priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size; Prometheus not suitable for per-request billing as collected data lacks 100% accuracy
  • They diverge on capability: Chef covers Recipes, Prometheus covers Multi-dimensional Data Model.

Where each one falls short

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

Chef

  • Priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size
  • Tripling the price between the two published tiers puts compliance and audit features well above basic automation
  • Enterprise Plus and every self managed deployment are custom quoted with no published price

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
