There are many Prometheus mixins that provide pre-defined rules for alerting.
However, if one adopts Grafana Alerting for everything, there doesn’t seem to be a way to benefit from these rules because 1) Grafana doesn’t understand them and 2) Grafana Alertmanager cannot accept alerts from Prometheus (which would be able to evaluate the rules).
Is manually converting community-based Prometheus rules to Grafana by using the web UI the only way?
