Worked on the aws/amazon-cloudwatch-agent repository to enhance memory observability by introducing a new metric for shared memory usage, labeled mem_shared, with its unit defined as Bytes. Leveraging Go and expertise in system metrics, the developer registered and integrated this metric into the CloudWatch Agent, enabling more granular monitoring and supporting faster diagnostics for memory-related issues. The work focused on feature delivery and code stability, with no major bugs addressed during the period. These improvements provided better visibility into the agent’s memory footprint, supporting cost control and data-driven performance tuning for users managing cloud infrastructure at scale.
