iris health and Grafana

I did a google search for 'Grafana' and 'IRIS Health'.

This gave these candidates:

https://github.com/caretdev/grafana-intersystems-datasource
https://community.intersystems.com/post/using-grafana-directly-iris
https://grafana.com/grafana/dashboards/14869

Does anyone know which one is 'best'?
If you have used any of these, do you have any detailed instructions on how to install?
Most of these packages assume you know how to install and run them and so are very light on how to install.

I'm using Grafana on a Windows platform (without the use of docker)
