Setting up a monitoring stack in Kubernetes with Prometheus and Grafana on Azure Kubernetes Service (AKS) can provide better visibility into pod and node metrics.
Prometheus scrapes and stores time-series data from Kubernetes, while Grafana offers customizable dashboards for insights into cluster performance.
Prerequisites include having Azure CLI authenticated, kubectl configured to AKS cluster, Helm 3 installed, and a working AKS cluster.
Key steps involve adding Helm repos, installing Prometheus and Grafana using Helm charts, accessing Grafana UI, importing dashboards, and learning lessons like setting up alerts for critical metrics.
