Worked on the apache/solr repository to address a critical UI bug affecting memory usage metrics in the Solr Admin interface. Focused on correcting the heap usage percentage calculation by updating JavaScript and HTML code to reference the maximum heap value rather than the committed heap, ensuring more accurate monitoring data. This targeted fix improved the reliability of operational dashboards and reduced the risk of false alerts in memory monitoring. The work was delivered with minimal changes to the user interface, underwent code review and testing, and adhered to Solr project standards, demonstrating careful attention to quality and alignment with project requirements.
