Billing metrics can be collected from AWS by using the Datadog-AWS Billing integration.
Further information on this can be found within the app here:
To begin collecting billing metrics, it is necessary to select "Billing" on the AWS configuration tile and include the permission 'budgets:ViewBudget' in your Datadog AWS policy.
You must also enable billing metrics within the AWS Console.
The following metrics are currently available using the Datadog-AWS Billing integration:
|aws.billing.actual_spend||dollars||The actual spending costs for your budget period|
|aws.billing.budget_limit||dollars||The spending limit for your budget period|
|aws.billing.estimated_charges||dollars||The estimated charges for your AWS usage. This can either be estimated charges for one service or a roll-up of estimated charges for all services.|
|aws.billing.forecasted_spend||dollars||The forecasted spending costs for your budget period|
For more robust cost monitoring across a number of cloud services in addition to AWS, Datadog supports 3rd-party integration with CloudHealth. This blog post has a more in-depth look at how CloudHealth integrates with Datadog to enable visibility of cost across your hosted infrastructure.
