-## Circuit metrics
+## ExpressRoute metrics
 
 To view **Metrics**, navigate to the *Azure Monitor* page and click *Metrics*. To view **ExpressRoute** metrics, filer by Resource Type *ExpressRoute circuits*. To view **Global Reach** metrics, filter by Resource Type *ExpressRoute circuits* and select an ExpressRoute circuit resource that has Global Reach enabled. To view **ExpressRoute Direct** metrics, filter Resource Type by *ExpressRoute Ports*. 
 
 Once a metric is selected, the default aggregation will be applied. Optionally, you can apply splitting, which will show the metric with different dimensions.

+### Bits In and Out - Metrics across all peerings
 
 You can view metrics across all peerings on a given ExpressRoute circuit.

-## Bits In and Out - Metrics per peering
+### Bits In and Out - Metrics per peering
 
 You can view metrics for private, public, and Microsoft peering in bits/second.

-## BGP Availability - Split by Peer  
+### BGP Availability - Split by Peer  
 
 You can view near to real-time availability of BGP across peerings and peers (Primary and Secondary ExpressRoute routers). This dashboard shows the Primary BGP session up for private peering and the Second BGP session down for private peering.

-## ARP Availability - Split by Peering  
+### ARP Availability - Split by Peering  
 
 You can view near to real-time availability of [ARP](https://docs.microsoft.com/azure/expressroute/expressroute-troubleshooting-arp-resource-manager) across peerings and peers (Primary and Secondary ExpressRoute routers). This dashboard shows the Private Peering ARP session up across both peers, but complete down for Microsoft peering across peerings. The default aggregation (Average) was utilized across both peers.
