## What the models said for it

- "Kubernetes & Cloud-Native (Budget Aware) | Prometheus + Grafana | Industry standard, native Kubernetes support, highly customizable." (Gemini 3.5 Flash, Infra monitoring)
- "1. Open-Source Stack (Most Economical)
Prometheus + Grafana + OpenTelemetry

- Cost: Completely free (open source)" (GLM 4.7 FlashX, Observability)
- "the best choice is usually Prometheus if your main workload is monitoring/metrics, because it's free, open source" (GPT-5.4 mini, Time series DBs)
- "Choose established options like Prometheus, VictoriaMetrics, or ClickHouse for most use cases" (MiniMax M2.5, Time series DBs)

## And against it

- "Prometheus as a primary long-term, large-scale TSDB... be cautious if you need multi-year retention, high availability, or broad analytical queries." (Perplexity Sonar, Time series DBs)
- "Using local Prometheus TSDB disk storage to retain multi-year historical metrics will eventually lead to slow queries and OOM crashes" (Gemini 3.5 Flash, Time series DBs)
- "Open-source like Zabbix/Prometheus + Grafana work if you have in-house talent for maintenance, but they add operational burden." (Grok 4.20, Infra monitoring)
- "Don't expose Prometheus, Alertmanager, exporters, or their metrics and debugging endpoints directly to the public internet." (GPT-6 Luna, Infra monitoring)
