EDIT- Nevermind, I had to reinstall the service and SimpleJson shows as the data source. However, my above question still remains.
/Also, I extracted the simple json datasource into /data/plugins and I see that in the plugins when I go to the server but not as a data source? I’m using these instruction. Also, this “grafana-cli plugins install grafana-simple-json-datasource” command wouldn’t work which is why I extracted the files into the plugin folder/
