What Grafana version and what operating system are you using?
Grafana 9.3.2 / Ubuntu 20.04 (TIG stack)
What are you trying to achieve?
Trying to add a Prometheus data source
How are you trying to achieve it?
- Use URL: http://10.0.0.14:9888/metrics
- Click Save & test
- UI error: Error reading Prometheus: An error occurred within the plugin
- Journal log:

What did you expect to happen?
I expected to see a connection on the remote server hosting the Prometheus URL. Instead, I see Grafana trying to connect to localhost and failing. When I use curl from the Grafana server I can connect so it’s not a firewall or connectivity issue.
Can you copy/paste the configuration(s) that you are having problems with?
Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
Did you follow any online instructions? If so, what is the URL?
I’m trying to get this data source working in Grafana: GitHub - camptocamp/ipahealthcheck_exporter: Prometheus exporter for exposing ipa-healthcheck tool checks as metrics
