Problems with Grafana and InfluxDB

Hey there,

I’m using Icinga2 with Grafana and InfluxDB, and the Graphs are displayed very well in Icinga2 itself.

But on my Grafana Web-Interface I don’t see any data on the Graphs on all of my importet dashboards. There are just no data points visible, and I’m not able to choose from the dropdown-menu for hosts etc. See the attached screenshot of one of my used dashboards:

My settings in Grafana are as followed:

The Icinga2-Default dashboard is also only showing one emtpy graph instead of the many that are visible in my Icinga2-environment.

Can anyone help me on this? Or is it even something that can be ignored?

Greetings

Is there anything that can be done about that, or do you have some guidance on this? Or do you miss technical data from me?
