Lambda waste check
Unused Lambda
unused_lambda
What it finds
Unused Lambda: one of the Lambda checks in the serverless optimization group. Checks in this group look for: serverless functions, state machines and APIs that are unused, mis-sized, on an old runtime, or configured in a way that bills more than needed.
Why it costs money
Serverless bills per request and per unit of memory and time, so a wrong setting multiplies on every invocation.
How it is detected
Zero invocations for 30 days
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.
