ExpressRoute monitoring, metrics, and alerts

This article helps you understand ExpressRoute monitoring, metrics, and alerts using Azure Monitor. Azure Monitor is one stop shop for all metrics, alerting, diagnostic logs across all of Azure.

Note

Using Classic Metrics is not recommended.

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.

    Note

    Using GlobalGlobalReachBitsInPerSecond and GlobalGlobalReachBitsOutPerSecond will only be visible if at least one Global Reach connection is established.

    Circuits metrics

    Bits In and Out - Metrics across all peerings

    You can view metrics across all peerings on a given ExpressRoute circuit.

    circuit metrics

    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

    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

    You can view near to real-time availability of ARP 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.

    ExpressRoute Direct Metrics

    You can view the admin state for each link of the ExpressRoute Direct port pair.

    er direct admin state

    You can view the bits in per second across both links of the ExpressRoute Direct port pair.

    er direct bits in per second

    You can also view the bits out per second across both links of the ExpressRoute Direct port pair.

    er direct bits out per second

    You can view the line protocol across each link of the ExpressRoute Direct port pair.

    er direct line protocol

    You can view the Rx light level (the light level that the ExpressRoute Direct port is receiving) for each port. Healthy Rx light levels generally fall within a range of -10 to 0 dBm

    er direct line Rx Light Level

    You can view the Tx light level (the light level that the ExpressRoute Direct port is transmitting) for each port. Healthy Tx light levels generally fall within a range of -10 to 0 dBm
