Kubernetes monitoring is a complex process that requires attention to various metrics across different layers, including services, containers, pods, deployments, nodes, and clusters, to ensure the health and performance of a project. Key tools such as kube-state-metrics, Metrics Server, and cAdvisor provide insights into resource utilization and the state of Kubernetes objects, which can be crucial for identifying and resolving potential issues like memory leaks. While cluster-level metrics offer a high-level overview, more granular monitoring of nodes, pods, and containers is essential for pinpointing performance bottlenecks and optimizing resources. Prometheus and Grafana are recommended for scraping, analyzing, and visualizing these metrics, allowing for effective monitoring and management of Kubernetes environments. Kubernetes Monitoring in Grafana Cloud offers a comprehensive solution with prebuilt dashboards and alerts, accessible to all users, including those on the free tier.
