# StartOTelEnrichment
<a name="API_StartOTelEnrichment"></a>

Enables enrichment and PromQL access for CloudWatch vended metrics for [supported AWS resources](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/UsingResourceTagsForTelemetry.html) in the account. Once enabled, metrics that contain a resource identifier dimension (for example, EC2 `CPUUtilization` with an `InstanceId` dimension) are enriched with resource ARN and resource tag labels and become queryable using PromQL.

Before calling this operation, you must enable resource tags on telemetry for your account. For more information, see [Enable resource tags on telemetry](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/EnableResourceTagsOnTelemetry.html).
