How see multiple dashboard (from different servers) on the same page?

I have found several forum posts asking about this with no answers.

I have X identical servers. I want to watch stats for all of them on the same page.

I was able to export and import the .json file so they all have identical dashboards, but I have to open X browser tabs to see them all at once.

How does one do this?

I’m not a good teacher, but I succeed to do This kind of Dashboards. You should work with templating, repeat panel and variables to do this job…

How does one get data from one Grafana instance to another on another server?

There is a piece of the puzzle still missing here.
