Monitoring Systems with Prometheus and Grafana

Prometheus and Grafana form the backbone of modern metrics-based observability, yet many teams struggle to move from “we collect metrics” to “we understand our systems.”

This talk builds a clear mental model for Prometheus and Grafana: how metrics are exposed, scraped, stored, queried, and visualized — and how those metrics connect to real operational decisions. We’ll explore Prometheus architecture, PromQL, Kubernetes integration via the Prometheus Operator, and how metrics power advanced workflows like canary deployments with Argo Rollouts and OpenTelemetry-based telemetry.

Attendees will leave knowing what to measure, how to measure it, and where to start on Monday.

This talk builds a practical mental model for metrics-based observability using Prometheus and Grafana. Rather than focusing solely on dashboards, we’ll explore how metrics are exposed, collected, queried, and ultimately used to make real operational decisions. We’ll connect application-level instrumentation, Kubernetes-native monitoring, and modern telemetry standards, showing how Prometheus fits into today’s production environments and deployment workflows.
