I am using Prometheus 2.33 version. The following query does not work.
kubelet_volume_stats_available_bytes
kubelet_volume_stats_capacity_bytes
The following query is used to monitor the DISK usage of the POD.
container_fs_usage_bytes
container_fs_limit_bytes
Is there a way to get the usage of PVC, Limit value?
For PVC, Kubernetes exposes these metrics to Prometheus, you can use them to monitor a persistent volume's usage:
kube_persistentvolume_capacity_bytes
kube_persistentvolumeclaim_resource_requests_storage_bytes
EDIT: These metrics are from kube-state-metrics - a service that produces Prometheus format metrics based on the current state of the Kubernetes native resources. It is basically listening to Kubernetes API and gathering information about its resources and objects, in particular for PV - PV metrics and PVC - PVC metrics. More information about the service is here.
