Complete and reliable monitoring of the WLCG data transfers is an important condition for effective computing operations of the LHC experiments. WLCG data challenges organized in 2021 and 2022 highlighted the need for improvements in WLCG data traffic monitoring. In particular, it concerns the implementation of remote data access monitoring via the root protocol. It includes data access to native XRootD storage, as well as to other storage solutions. We refer to it as XRootD monitoring. 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.
