SageMaker waste check
Stopped SageMaker Notebook Storage
stopped_sagemaker_notebook_storage
What it finds
Stopped SageMaker Notebook Storage: one of the SageMaker checks in the ml/ai optimization group. Checks in this group look for: machine learning endpoints and notebooks that are idle, stopped but still billing for storage, or larger than their workload needs.
Why it costs money
Hosted notebooks and endpoints bill for the instance hours and storage they hold, not for the models they serve.
How it is detected
Stopped notebook with an ML storage volume
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
None of Trusted Advisor, Cost Optimization Hub or Compute Optimizer flags this.
Checked against the AWS documentation.
Run it yourself
Nothing leaves your machine. The local scan has no telemetry.
