Kubernetes monitoring is essential for maintaining the health and availability of containerized applications, requiring attention to both cluster-wide and pod-specific metrics. Important aspects to monitor include node load, unsuccessful pods, and cluster usage at the cluster level, while pod-specific monitoring focuses on the number of pod instances and deployment configurations. Tools like Prometheus, Grafana, and Alertmanager, often used alongside kube-state-metrics, provide comprehensive solutions for monitoring and alerting by collecting and visualizing metrics related to node performance and Kubernetes operations. Logs play a crucial role in troubleshooting, offering detailed insights into cluster and application activities, while Kubernetes events capture resource state changes and decisions within the cluster. Despite limitations like retention periods and accessibility, these events are vital for diagnosing issues, and open-source tools can enhance their usability.
