Grafana 6.6 introduces a new feature that allows administrators to enforce a minimum interval between alert rule evaluations, addressing requests to limit the frequency of evaluations that can cause excessive backend load. Implemented by @Uepoch, this feature enables administrators to set a global configuration, alerting.min_interval_seconds, ensuring that if a user-defined alert rule frequency is lower than the set minimum, the minimum interval will be enforced, with users receiving notifications of any adjustments. This change applies to both new and existing alert rules, allowing administrators to better manage server load by overriding individual rule frequencies with a globally imposed interval. Grafana v6.6 also includes enhancements to several features, such as Alerting, CloudWatch, Explore, Loki, Graphite, and Stackdriver.
