Panel Reviews
The Builder
Developer Perspective
“The standard for metrics. PromQL is powerful, the ecosystem is massive, and it pairs perfectly with Grafana.”
The Skeptic
Reality Check
“Battle-tested at every scale. The pull model and service discovery integration are well-designed.”
The Futurist
Big Picture
“Prometheus + Grafana is the open-source observability stack. Mimir extends it to global scale.”

“PromQL is complex to learn but the expressiveness once you get it is unmatched”
“Prometheus + Grafana is still the gold standard for Kubernetes monitoring in 2025”
“Cardinality explosion is real — had to rewrite all our labels after our bill spiked”
“Open-source, battle-tested, CNCF graduated — this is what good infra tooling looks like”
