-            <p>
-              There are two ways to authenticate the Google Cloud Monitoring plugin. You can upload a Service Account
-              key file or automatically retrieve credentials from the Google metadata server. The latter option is only

-            <p>
-              If Grafana is running on a Google Compute Engine (GCE) virtual machine, it is possible for Grafana to
-              automatically retrieve the default project id and authentication token from the metadata server. In order
-              for this to work, you need to make sure that you have a service account that is setup as the default
-              account for the virtual machine and that the service account has been given read access to the Google
-              Cloud Monitoring Monitoring API.
