Complete and reliable monitoring of the WLCG data transfers is an important condition for effective computing operations of the LHC experiments. WLCG data challenges organised in 2021 and 2022 highlighted the need for improvements in the monitoring of data traffic on the WLCG infrastructure. In particular, it concerns the implementation of the monitoring of the remote data access via the XrootD protocol. This contribution describes the new implementation of the XrootD monitoring flow, the overall architecture, the deployment scenario and the integration with the WLCG global monitoring system.
