 You can view near to real-time availability of [ARP](./expressroute-troubleshooting-arp-resource-manager.md) (Layer-2 connectivity) across peerings and peers (Primary and Secondary ExpressRoute routers). This dashboard shows the Private Peering ARP session status is up across both peers, but down for Microsoft peering for both peers. The default aggregation (Average) was utilized across both peers.
