Developed a headroom visualization feature for the rabbitmq-server repository, enhancing the Overview Dashboard to display available disk space before publisher blocking occurs. Focused on improving observability and enabling proactive capacity planning, the work involved updating the RabbitMQ-Overview.json file and refining the underlying query logic to align with the "Disk space available before publishers blocked" metric. Leveraged skills in dashboard development, data visualization, and monitoring, primarily utilizing JSON for configuration and data representation. The resulting feature provided earlier detection of capacity risks and improved monitoring accuracy, supporting more informed operational decisions without introducing new bug fixes during the development period.
