## What the models said for it

- "Prometheus (for metrics collection) and Grafana (for visualization) form the de facto industry standard." (Gemini 3.5 Flash, Infra monitoring)
- "Choose Prometheus+Grafana for cloud-native/Kubernetes environments with strong technical teams" (Kimi K2, Infra monitoring)
- "building your own stack with Prometheus + Grafana + Loki if you have the time to manage it" (GLM 4.7 FlashX, Observability)
- "Kubernetes-heavy, cost-conscious, technical team → Prometheus + Grafana" (DeepSeek V4 Flash, Infra monitoring)

## And against it

- "Only choose this if you have a specialized Infrastructure Engineering team whose primary job is keeping the monitoring system running." (Qwen 3.7 Flash, Infra monitoring)
- "which are free but require your own infrastructure, engineering time for setup/maintenance, and scaling" (Grok 4.1 Fast, APM)
- "Open-source and flexible, but it costs more in engineering time to maintain." (Perplexity Sonar, Infra monitoring)
- "Prometheus + Grafana - Open-source; requires more operational overhead" (Claude Haiku 4.5, Observability)
