Use AWS Budgets advanced filtering options to extend your cost monitoring capabilities
AWS Budgets gives you the ability to set custom budgets that alert you when costs and usage exceed (or are forecasted to exceed) your user-defined thresholds. Using AWS Budgets, you can monitor your total monthly costs or refine your budgets to track costs associated with specific usage dimensions (e.g., Amazon EC2 resource costs tagged as project: secretProject for a set of linked accounts).
Starting today, you can use the new advanced filtering capabilities to quickly and easily control the specific cost categories you want to include in, or exclude from, your budget. These advanced filtering options include: credits, refunds, upfront reservation fees, recurring reservation charges, AWS Support charges, subscription costs, and taxes. For example, you can now set budgets that track your variable usage (e.g. Amazon EC2 instance hours, Amazon S3 storage, and data transfer charges) and exclude any one-time costs (e.g., upfront reservation fee) and recurring charges (e.g., AWS Support charges).
To learn more about using advanced filtering options to build granular cost budgets, refer to the Managing your Costs with Budgets user guide or the AWS Budgets webpage.
