+Simple prometheus exporter that exports ephemeral storage metrics usage per pod.
 Such metric was not present in kubelet metrics at the moment of writing this.
-Discussion for adding it is in [Exposing ephemeral storage metrics to prometheus](https://github.com/kubernetes/kubernetes/issues/69507) issue.

 The data is collected from kube-api-server nodes API. Metrics value is in bytes.
 
 ## Limitation
 
-Kube-api-server does not return per container value for storage usage, so we сan have  metric only per pod and not per container.
-Keep in mind that [kubelet](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/stats/helper.go#L399) counts pod's logs as ephemeral storage.
