Monitoring VPN Gateway
You can monitor Azure VPN gateways using Azure Monitor. This article discusses metrics that are available through the portal. Metrics are lightweight and can support near real-time scenarios, making them useful for alerting and fast issue detection.

|BGP Routes Advertised||Count||5 minutes||Number of routes advertised per peer and per instance.|
|BGP Routes Learned||Count||5 minutes||Number of routes learned per peer and per instance.|
|Gateway P2S Bandwidth||Bytes/s||1 minute||Average combined bandwidth utilization of all point-to-site connections on the gateway.|
|Gateway S2S Bandwidth||Bytes/s||5 minutes||Average combined bandwidth utilization of all site-to-site connections on the gateway.|
|P2S Connection Count||Count||1 minute||Count of point-to-site connections on the gateway.|
|Tunnel Bandwidth||Bytes/s||5 minutes||Average bandwidth utilization of tunnels created on the gateway.|
|Tunnel Egress Bytes||Bytes||5 minutes||Number of outgoing bytes from a tunnel.|

|Tunnel Egress Packets||Count||5 minutes||Number of outgoing packets from a tunnel.|
|Tunnel Egress TS Mismatch Packet Drop||Count||5 minutes||Number of outgoing packets dropped by tunnels caused by traffic-selector mismatch.|
|Tunnel Ingress Bytes||Bytes||5 minutes||Number of incoming bytes to a tunnel.|
|Tunnel Ingress Packet Drop Count||Count||5 minutes||Number of incoming packets dropped by a tunnel.|
|Tunnel Ingress Packets||Count||5 minutes||Number of incoming packets to a tunnel.|
|Tunnel Ingress TS Mismatch Packet Drop||Count||5 minutes||Number of incoming packets dropped by tunnels caused by traffic-selector mismatch.|
|Tunnel MMSA Count||Count||5 minutes||Number of main mode security associations present.|
|Tunnel Peak PPS||Count||5 minutes||Max number of packets per second per tunnel.|
|Tunnel QMSA Count||Count||5 minutes||Number of quick mode security associations present.|
|Tunnel Total Flow Count||Count||5 minutes||Number of distinct flows created per tunnel.|
|User Vpn Route Count||Count||5 minutes||Number of user VPN routes configured on the VPN Gateway.|
