Hi Kanex, i think you have to check your data source settings for pnp in grafana.
I set it up like linked post from @KONY ([Check_mk (english)] Make Grafana with PNP plugin work with Check_MK CRE on one host) that works for me.
In case the connection works you only have to click on “select host” in query an you get a list of all your hosts you monioterd with checkmk. Hope it helps…
