We are happy to announce the preview of ExpressRoute monitoring usingNetwork Performance Monitor(NPM). With NPM, you can now monitor end-to-end connectivity and performance between your branch offices and VNETs in Azure, over ExpressRoute.
NPM discovers your ExpressRoute circuit connections and routers across Microsoft and service provider edge and campus networks.
Monitor connectivity to your workloads in Azure and identify specific hops that cause performance degradation for your users. View the health of these hops on an interactive network topology map.
View the state of your network at any point in the past, with theNetwork State Recorderfeature. This helps identify transient issues that network admins often struggle with.
