Kubernetes Monitoring now includes a Storage tab showing Persistent Volume Claims across your clusters, giving visibility into storage alongside your existing pod and node metrics.
Each row shows the Persistent Volume name, cluster, status, claim name, storage class, and capacity. Filter by Persistent Volume type, cluster, or status, or search by name.
This should make storage issues visible in the same place you already check pod and node health, instead of needing kubectl to see what's bound, how much capacity is used, or what's stuck pending.
Check out the Kubernetes Monitoring documentation for full details.
