Bolek Ziobrowski · Answer

Hi John Did you follow <https questdb io blog 2020 10 19 grafana tutorial > Could you share questdb logs

Miguel Arregui · Answer

yes I have hit the same error my grafana was installed with `brew install grafana` and that error shows when I hit the `Save amp Test` button after having added QuestDB as a datasource with Postgresql version 9 4

Nicolas Hourcard · Answer

< Amy Wang> could we look at this tutorial and tweak accordingly

Miguel Arregui · Answer

I can add QuestDB 7 0 1 to grafana 9 3 8 as a datasource ```docker run it rm name=grafana p 3000 3000 grafana grafana 9 3 8``` the problem comes when I go beyond this release The next up is grafana grafana 9 4 0 beta1 and this one already has the problem reported by < John Dyer>
