Datadog bills for AWS hosts running the Datadog Agent and all EC2 instances picked up by the Datadog-AWS integration. You are not billed twice if you are running the Agent on an EC2 instance picked up by the AWS integration.
Other AWS resources (ELB, EBS, RDS, Dynamo, etc.) are not part of monthly billing and configuration exclusions do not apply.
Use the Datadog-AWS integration tile to control your metric collection. Go to the Configuration tab and select an account or add a new one. Each account is controlled under Optionally limit metrics collection. Limit metrics by host tag or per namespace:
When adding limits to existing AWS accounts within the integration tile, the previously discovered instances could stay in the Infrastructure List up to 24 hours. During the transition period, EC2 instances display a status of
???. This does not count towards your billing.
Hosts with a running Agent still display and are included in billing. Using the limit option is only applicable to EC2 instances without a running Agent.
