 ## Prerequisites
 
 * **Sumo Logic Metrics**. The AWS Observability Solution leverages both logs and metrics to provide comprehensive monitoring and troubleshooting of your AWS cloud infrastructure. If you do not already have Metrics, contact your Sumo Logic account representative. AWS Observability integrates with the [AWS Observability view](/docs/dashboards/explore-view/#aws-observability) by populating metadata and only shows entities with metrics coming in. If you do not see expected entities, make sure configurations are correct to collect and receive metrics including the [CloudWatch Namespace](/docs/observability/aws/deploy-use-aws-observability/deploy-with-aws-cloudformation) for CloudFormation Template.
