Description
During the first WLCG Network Data Challenge in fall of 2021 some shortcomings in the monitoring that impeded the ability to fully understand the results collected during the data challenge were identified. One of the simplest missing components was site specific network information, especially information about traffic going into and out of any of the participating sites. Without this information, it is very difficult to understand which sites are experiencing bottlenecks or might be misconfigured or under utilized based on their capacity. The WLCG Monitoring Task Force, formed at the end of 2021, was tasked with three main work areas, one of which was site network monitoring. We will describe the work being carried out in the task force to augment our knowledge of networking use for WLCG by enabling site network documentation and use, the status of the deployment and the implications for the next data challenge.
