## Overview{% #overview %}

[Google Cloud App Hub](https://docs.cloud.google.com/app-hub/docs/overview) is the central registry for your applications on Google Cloud. It groups related services and workloads into logical applications and attaches ownership, criticality, and environment metadata. App Hub organizes your resources by application rather than by the standard project hierarchy.

Use the Datadog Google Cloud Platform integration to collect metrics about the applications, services, and workloads registered in App Hub, including discovery counts and per-application quota usage.

## Setup{% #setup %}

### Installation{% #installation %}

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