Monitor CloudWatch Dashboard for upscale event

As the DML load is generated on the source database, monitor the AWS DMS console and CloudWatch dashboard for DMS capacity usage. Once the load exceeds 80%, You will see Scale-up event being triggered.

Capacity Utilization Graph

1. To access CloudWatch metrics for DMS Serverless Replication, navigate to the AWS DMS console, select “Serverless replications” in the left sidebar, choose your serverless replication, and look for the Capacity Utilization graph under the Monitoring tab.

   You can look into more detail by clicking on Maximizing Capacity Utilization.

   

2. Once the load exceeds 80%, you can check the logs after 10 minutes to confirm that the event has triggered the scaling up of the DCU.

This concludes our DMS Serverless Scale-up lab. Please proceed to the next lab to learn how to monitor the scaling-down event.
