## Overview{% #overview %}

Azure VPN Gateway sends encrypted traffic between an Azure virtual network and on-premises locations, or between virtual networks, over the public internet or via ExpressRoute. This integration surfaces throughput, tunnel, and connection metrics across VPN gateways, virtual network gateways, site-to-site connections, and point-to-site VPN gateways.

## Setup{% #setup %}

### Installation{% #installation %}

If you haven't already, set up the [Microsoft Azure integration](https://docs.datadoghq.com/integrations/azure.md) first. There are no other installation steps.

## Data Collected{% #data-collected %}
