Also to mention frequently asked feature: alerts using queries and templated variables [1][2]. Creating even simple generic dashboards with alerts is not possible, unless variables are hardcoded in hidden queries.
Agreed. If Grafana alerts supported templated variables I would migrate a decent chunk of my monitoring stack. But without templated variables the alert system feels half baked and I almost prefer it not even be a feature.
