Where each one falls short

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

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

Ubiquiti UniFi

  • Product page states no licensing fees but publishes no hardware price; buyers must go to the Ubiquiti Store or an authorized distributor for a figure
  • Newest WiFi 7 access points such as the U7 Pro require compatible UniFi controller hardware or cloud console to manage centrally
