so we have the ability to fetch from cloudwatch, however this doesn’t cover generic data transfer costs. I think the best thing to look at the cost explorer and try and drill down into the “data transfer” usage type group. I’ve used this article in the past as a decent guide to trying to debug data transfer costs. Then once you have a decent idea of the thresholds, just add it into the usage Infracost usage manually. Or you could set up a github action/scheduled job to try and fetch these values on a schedule. e.g. https://aws.amazon.com/premiumsupport/knowledge-center/cloudwatch-getmetricdata-api/ I know this isn’t ideal atm, but we have expanded fetch metrics from cloud on our roadmap. It’s something we’re passionate about making a better experience for users.

@nutritious-musician-34507 is this what you were looking for?

this is just a usage convention invented by infracost?
