Compute Optimizer waste check
Oversized EC2 Optimizer
oversized_ec2_optimizer
What it finds
Oversized EC2 Optimizer: one of the Compute Optimizer checks in the compute optimization group. Checks in this group look for: compute capacity that is idle, stopped but still holding paid attachments, oversized for its load, or on an older generation.
Why it costs money
Compute is billed for the time it is provisioned, not for the work it does, so capacity nobody uses keeps billing.
How it is detected
AWS ML-based rightsizing recommendation
Detection confidence: HIGH. This is the criterion from our public docs. It runs in a local scan with your own read-only credentials.
Run it yourself
Nothing leaves your machine. The local scan has no telemetry.
