I’m trying to get the total number of provisioned of read capacity units of a DynamoDB table to calculate the cost of one specific table in a month, using CloudWatch metrics. This table has been switched from Provisioned to On-Demand, all of its metric statistics has been reset, so I don’t know how many RCU has been used when it was in Provisioned mode. I’m also not allowed to manage tags used for calculating cost, so Cost Explorer is pretty much a “no go”.
