As organizations scale their data processing and analytics workloads on Amazon EMR on EC2, observability across cluster health, job execution, and resource usage becomes increasingly important. Teams often manage log collection across distributed nodes, correlate Amazon EMR steps with underlying YARN applications, and configure monitoring agents to capture the right level of detail for their environment.

In this post, we walk you through five key enhancements: Amazon CloudWatch Logs integration, step-level Amazon Simple Storage Service (Amazon S3) logging controls, expanded console UIs for YARN and Tez, Amazon EMR step to YARN application ID mapping, and enhanced custom metrics with updated documentation.
