**Tell us about your request**
I would like a Fargate equivalent of https://aws.amazon.com/ec2/spot/instance-advisor/ .

**Which service(s) is this request for?**
Fargate Spot

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
I'd like to have parity between the information I have with EC2 Spot and Fargate Spot so that I can balance container sizes and locations with interruption probability, and determine as a whole the interruption rate for Fargate Spot containers in a given region.

**Are you currently working around this issue?**
No

The request concerns an AWS Fargate Spot equivalent of the EC2 Spot Instance Advisor. No repository files, tests, or implementation entry points are mentioned; first clarify where Fargate Spot interruption data comes from and what region, size, location, and interruption-rate outputs would define completion.
