Architecture dashboards samples

Hi,
Is there any sample architecture dashboards available so that it can be imported and edited as per the requirement. Also is it possible to have in single stats or other panel ex: Total 6 / 6 up or example how can this dashboard be implemented in grafana?. demo.nginx.com

Not sure what exactly you mean by architecture, but maybe check out https://play.grafana.org/ for some inspiration? You can export and use any of the dashboards on there.

I would like to put dashboard of all infrastructure flow like from FE -API - APP - DB - Other services. All the services are up or down status of total (6/6) need to be displayed on the dashboard. There is a diagram plugin but i would like to have without using the plugin. I had a look at play.garfana.org but couldnt find. Similar i found is (http://demo.nginx.com/ but not in grafana.
