# Google Cloud VPN

## Overview{% #overview %}

Google Cloud VPN securely connects your existing network to your Google Cloud Platform network.

Get metrics from Google VPN to:

- Visualize the performance of your VPNs.
- Correlate the performance of your VPNs with your applications.

## Setup{% #setup %}

### Installation{% #installation %}

If you haven't already, set up the [Google Cloud Platform integration first](https://docs.datadoghq.com/integrations/google-cloud-platform.md). There are no other installation steps that need to be performed.

### Log collection{% #log-collection %}

Google Cloud VPN logs are collected with Google Cloud Logging and sent to a Dataflow job through a Cloud Pub/Sub topic. If you haven't already, [set up logging with the Datadog Dataflow template](https://docs.datadoghq.com/integrations/google-cloud-platform.md#log-collection).

Once this is done, export your Google Cloud VPN logs from Google Cloud Logging to the Pub/Sub topic:

1. Go to the [Google Cloud Logging page](https://console.cloud.google.com/logs/viewer) and filter the Google Cloud VPN logs.
1. Click **Create Export** and name the sink.
1. Choose "Cloud Pub/Sub" as the destination and select the Pub/Sub topic that was created for that purpose. **Note**: The Pub/Sub topic can be located in a different project.
1. Click **Create** and wait for the confirmation message to show up.
