32. Scale Validation of the XRootD Monitoring pipeline

Derek Weitzel (University of Nebraska Lincoln (US))

Derek Weitzel will cover the work to verify the transfer accounting of XRootD and the OSG’s XRootD Monitoring Collector pipeline which is replacing the legacy GLED collector currently hosted at UCSD. We found that the single largest issue with the monitoring is the unreliable communication between the XRootD instances and the collectors since it uses the UDP protocol.
