## What the models said for it

- "If you have strong engineering talent, investing time in open-source solutions like Prometheus + Grafana can provide excellent monitoring at minimal direct cost." (Claude Haiku 4.5, Infra monitoring)
- "Safer Bets: Open-source like Prometheus/Grafana for control; avoid if you lack ops expertise." (Grok 4.1 Fast, Observability)
- "Grafana + Prometheus + Loki + Tempo (or Mimir) is the enterprise favorite" (DeepSeek V4 Flash, Infra monitoring)
- "For Kubernetes & Microservices: Start with Prometheus + Grafana." (Qwen 3.7 Flash, Infra monitoring)

## And against it

- "prefer tools with native Kubernetes support ... (e.g., Prometheus or New Relic's K8s integration)" but "Setting up, securing, and scaling a self-hosted Prometheus/Grafana cluster"" (Qwen 3.7 Flash, Infra monitoring)
- "open-source Prometheus and Grafana are only "free" if you don't calculate the engineering hours spent building, updating, and hosting them" (Gemini 3.5 Flash, Infra monitoring)
- "While platforms like raw Prometheus + Grafana are popular, using them as a "black box" solution is a trap for many organizations." (Qwen 3.7 Flash, Observability)
- "rarely have a dozen dedicated SREs to spend their days maintaining open-source infrastructure (like vanilla Prometheus and Thanos)" (Gemini 3.5 Flash, Observability)
