What Grafana version and what operating system are you using?
What are you trying to achieve?
Create and Edit Prometheus rules using Grafana version 8 integrated alerting
How are you trying to achieve it?
Attempting to add Prometheus as a data source when creating a rule
Prometheus does not appear on the list (but it is configured and working elsewhere in Grafana)
What did you expect to happen?
I expected it to appear.
Can you copy/paste the configuration(s) that you are having problems with?
I could, but which part?
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?
No, they are incomplete. They say to use the legacy api, but not how.
