Resource tags for telemetry

Use Amazon CloudWatch to discover, visualize, and alert on your AWS infrastructure metrics by AWS resource tags. You can set up comprehensive monitoring with CloudWatch metrics and alarms using tags. This helps monitor cloud infrastructure at scale by adapting alarms and metrics analysis as resources change.

To begin discovering and visualizing your telemetry by tags, you must first enable the resource tags for telemetry feature for your AWS account. When you enable this feature, Resource Explorer creates an AWS index and managed view that indexes and discovers resources and tags in your account. For more information, see Index in the Resource Explorer API reference guide and AWS managed views in the Resource Explorer user guide. CloudWatch uses this information to enrich your AWS infrastructure metrics with related AWS resource tags. You can enable resource tags for telemetry at no additional cost.
