I’m a complete newb. I believe I’ve installed Prometheus and Grafana correctly (services are running and are reachable, Prometheus data source as been added—though I’ve had plenty of issues with that …).
I can manually create a simple dashboard panel with a PromQL query but if I import any preconfigured dashboards (using that source) no data is available.

We are excited that you joined our OSS community. Please read about some of the FAQs in the community
Please review the submission template and include more details:
What Grafana version and what operating system are you using?
Are you importing a dashboard from this page? if, so which one?
Getting any errors? Try increasing the verbosity of the Grafana server logs to debug and note any errors.
Did you follow any online instructions for installing Grafana / Prometheus? If so, what is the URL?
I am using the current version of Ubuntu 22.04. Grafana 9.3.6
I’ve imported many node-exporter dashboards. The problem seems consistent.
I’m not seeing any log errors but I could be doing it wrong LOL. I am using the log viewer.
I used a couple places for instructions. Main one here: https://www.digitalocean.com/community/tutorials/how-to-install-prometheus-on-ubuntu-16-04
I used the official install guide for Grafana: https://grafana.com/docs/grafana/latest/setup-grafana/installation/debian/
Hi @dean3e46,
Can you please share with us picture of one query from imported dashboard? I suspect that all those queries are mapped to data source which name differs from name of you data source.
For example I named my Prometheus data source “Prometheus123” and if queries in imported dashboard are mapped to different name (e.g. Prometheus) then queries won’t work:
Also please check if with imported dashboard you also got dashboard variable which define datasource (if that’s true then in query you would see something like ${variablename}:
Dashboard settings (cog icon in upper right corner) -> Variables
Maybe there is filter applied under “Instance name filter” field.
Best regards,

Many of the imports do ask for a datasource when importing (I’m thinking older ones didn’t?). There was only one imported dashboard where one of the variables was ‘datasource’ and is was set to the only source I had, Prometheus, and there were no filters applied.
