Description

This talk presents improvements to the OSG XRootD monitoring collector: fixing a critical t-stream parsing bug that fabricated bogus file-close records, adding topology and SciTags resolution, new Prometheus metrics, and expanded configurability for multi-VO deployments. We conclude with a validation of the collector against MonaLisa at CERN, confirming the fixes and establishing a cross-system XRootD monitoring baseline for WLCG.
