Creating Grafana alert rules with multiple Prometheus data sources

Monitoring and Observability Grafana

Hi. Does Grafana support having alert rules that run the same query but from multiple prometheus data source?

until now I have created a rule per prometheus instance for the same query.

Why do you need that ?

(because the solution might be different)

I have 5+ different prometheus connected to a single grafana and wanted to see if there was another way other than duplicating the alert rule and just changing the source.

Potentially then do one rule with the 5 datasources and have one trigger condition ?

I think you can create 1 alert Rule and add 5 queries with 5 different datasources and then add a condition to Trigger the alert.
