Compute Optimizer waste check
Oversized EBS Optimizer
oversized_ebs_optimizer
What it finds
Oversized EBS Optimizer: one of the Compute Optimizer 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
AWS ML-based IOPS/throughput analysis
Detection confidence: HIGH. 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.
