Metrics Kubernetes Kubelet For more information, see the documentation for the Kubelet integration. The set of metrics collected may vary depending on the version of Kubernetes in use. The ranking for eviction, however, was correct and the pod debug-887cd4775-2brw9 was the pod used to create the volume. Docs > Container Monitoring > Kubernetes > Kubernetes Data Collected This page lists data collected by the Datadog Agent when deployed on a Kubernetes cluster. when creating large file inside the container it is still able to create files more that the ephemeral-storage request and limit. but when when deploying the pod and it is not restricting the pod to use the defined ephemeral storage. Have defined ephemeral-storage request and limit in resources (-storage, -storage) on the deployment and verified that evictionHard: is enabled for "imagefs and "nodefs" on the node. So that other pods can use available space on /var/lib/docker which again restrict them to use other 20G for each pods. If there is a solution to restrict ephemeral storage for pods, for an example set a defined size (lets say 20G) for the pods, that particular pods only can use 20G on ephemeral storage and defined persistant volumes for more storage requirement. This is causing the high utilization on /var/lib/docker file system frequently. As it is found that ephemeral storage is shared across all the pods and that is going to be fill up /var/lib/docker frequently based on the pods writable layer and logs. I am moving it here.Īs discussed in #361, Looking for a solution to restrict ephemeral storage for pods usage. Opened an issue in kubernetes/enhancements.
