    <h5>GCP Service Account</h5>
    <p>
      To authenticate with the Stackdriver API, you need to create a Google Cloud Platform (GCP) Service Account for
      the Project you want to show data for. A Grafana datasource integrates with one GCP Project. If you want to
      visualize data from multiple GCP Projects then you need to create one datasource per GCP Project.
    </p>
    <p>
      The <strong>Monitoring Viewer</strong> role provides all the permissions that Grafana needs.
    </p>
    <p>
      The following APIs need to be enabled on GCP for the datasource to work:
      <ul>
        <li><a class="external-link" target="_blank" href="https://console.cloud.google.com/apis/library/monitoring.googleapis.com">Monitoring
            API</a></li>
        <li><a class="external-link" target="_blank" href="https://console.cloud.google.com/apis/library/cloudresourcemanager.googleapis.com">Resource
            Manager API</a></li>
      </ul>
    </p>
    <p>Detailed instructions on how to create a Service Account can be found <a class="external-link" target="_blank"
        href="http://docs.grafana.org/datasources/stackdriver/">in
        the documentation.</a></p>
