EBS waste check
Over Provisioned IOPS
over_provisioned_iops
What it finds
Over Provisioned IOPS: one of the EBS checks in the storage optimization group. Checks in this group look for: storage that no workload reads, writes or needs any more: unattached volumes, stale snapshots and backups, data with no lifecycle rule.
Why it costs money
Storage bills per gigabyte-month whether or not anything uses it, and forgotten copies pile up quietly.
How it is detected
Provisioned IOPS underutilized
Detection confidence: MEDIUM. This is the criterion from our public docs. It runs in a local scan with your own read-only credentials.
AWS's own tools
AWS flags this too, under "EBS volume recommendations (Not optimized)".
Checked against the AWS documentation.
Run it yourself
Nothing leaves your machine. The local scan has no telemetry.
