Hello Sagar! 👋 You are right, the example usage file doesn't mention

aws_db_instance

. However it supports one attribute:

monthly_standard_io_requests

. Here's how to use it:

aws_db_instance.my_db:
  monthly_standard_io_requests: 10000

@busy-agent-35515 thanks for your reply. I did this changes in usage file and now it's working fine.

Awesome! Please let me know if you need more help 🙂

@astonishing-oil-57884 did you try

infracost breakdown --path=... --sync-usage-file --usage-file=infracost-usage.yml

? that should have generated the params - but maybe it didn’t if we forgot to add it to https://github.com/infracost/infracost/blob/master/infracost-usage-example.yml ?

@white-airport-8778 I have not tried this command. I took infracost-usage-example.yml file from latest release.

cool - one last question, did you see https://www.infracost.io/docs/usage_based_resources at all? I’m curious how you discovered the usage-file feature

Yes I saw this ..
