During October 2025, Junda focused on enhancing observability in the apache/gravitino repository by addressing a metrics compliance issue. He identified that hyphens in metric names violated Prometheus conventions, which disrupted accurate metric scraping and dashboard stability. Using Java, he implemented a targeted bug fix that sanitized both metric prefixes and names through the Collector.sanitizeMetricName method. This adjustment ensured that metrics exposed at the /prometheus/metrics endpoint adhered to Prometheus standards, improving reliability across production and staging environments. Junda’s work leveraged his skills in bug fixing, metrics, and Prometheus, resulting in more accurate monitoring and reduced alert noise for the team.
