# Correlate Amazon ECS application performance using application metrics
<a name="metrics-data"></a>

Amazon ECS on Fargate supports collecting metrics from your applications running on Fargate and exporting them to either Amazon CloudWatch or Amazon Managed Service for Prometheus. 

You can use the collected metadata to correlate application performance data with underlying infrastructure data, reducing the mean time to resolve the problem. 

Amazon ECS uses an AWS Distro for OpenTelemetry sidecar container to collect and route your application metrics to the destination. The Amazon ECS console experience simplifies the process of adding this integration when creating your task definitions.
