New in Grafana 6.6: Forcing minimum alert evaluation frequency
There has long been a request from administrators to have the ability to enforce a minimum interval between alert rule evaluations. This is useful for restricting unrealistic user-defined alert rules that evaluate too often and create unnecessary load in the backend. @Uepoch took the initiative and made all the necessary modifications for this configuration in Grafana’s backend, and we finally pushed it forward and introduced the feature in Grafana v6.6.
