Jonathan Cantu enhanced the CMSgov/beneficiary-fhir-data repository by delivering two infrastructure features focused on observability and operational visibility. He implemented Prometheus JMX metrics exposure for Java applications, configuring exporters, environment variables, and container ports to enable effective metric scraping and dashboarding. In a separate effort, Jonathan introduced ECS EventBridge monitoring, capturing ECS cluster events and exporting them to CloudWatch by creating IAM policies, event rules, and log groups. Using AWS, Terraform, and HCL, he applied Infrastructure as Code principles to automate deployment. His work provided a foundation for proactive incident response and improved reliability, demonstrating depth in DevOps instrumentation.

February 2026 – CMSgov/beneficiary-fhir-data: Delivered ECS EventBridge monitoring for ECS cluster events to CloudWatch, enhancing observability and incident response. Implemented a monitoring rule to capture ECS cluster events and log them to CloudWatch, including creation of IAM policies, CloudWatch event rules, and log groups. This work is tied to BFD-4388 with commit 34020bcc0336aed20710cd84b0402139fb9d433e. No major bugs fixed this month. Overall impact: improved operational visibility, faster incident diagnosis, and stronger governance for beneficiary data services. Technologies demonstrated: AWS EventBridge, IAM, CloudWatch Logs, CloudWatch Events rules, and changeset traceability.
