In Kubernetes, in addition to metrics and logs from containers, we can get information about the operation of components using Kubernetes Events. Events usually store information about the status of Pods (creation, evict, kill, ready or not-ready status of pods), WorkerNodes (status of servers), Kubernetes Scheduler (inability to start a pod, etc.). Kubernetes Events types… Read More »
