I have a bunch of statefulset applications notably Kafka Brokers, and Kafka Stream client application, including some DB, all deployed in Kubernetes. I would like to be able to build a grafana dashboard which would include the IOPS on the disk of the application above.

Is there a way to monitor the disk IOPS of a pod, and if not of the node on which the application is running. What kubernetes Prometheus exporters exist our there that could give me this information ?
