Set up alerts on VPN Gateway metrics
Azure Monitor provides the ability to set up alerts for Azure resources. You can set up alerts for virtual network gateways of the "VPN" type.
For steps, see Tutorial: Create a metric alert for an Azure resource and Create, view, and manage metric alerts using Azure Monitor.
