The purpose of this dashboard is to show a couple of panels with the most relevant information. Effectively the app-metrics prometheus endpoint needs to have a "app_metrics_info" counter or something like that, in order to enable the "version" and "provisioned" panels only.

So it is not "metrics for metrics app" really, it's just an overview of "metrics app".

I liked what you did with the panel with links to other dashboards although I don't know what exactly "mobile app metrics" and "mobile device metrics" really mean.
