Finally able to take a look at this. I copied the postgresql datasource plugin and replaced all prostres names with ‘mydstest’ . Although I can see the datasource in the list, when I select it I get an error
Unexpected token ‘<’ Evaluating http://grafana.staged-by-discourse.com/public/app/plugins/datasource/mydstest/module Loading app/plugins/datasource/mydstest/module
Anybody having hints why is that ?
(Windows installation of grafana v7.0.3)
Edit: Unexpected token '<' Evaluating
There I got an answer for this problem.
