Grafana Labs has introduced a new filtering system for alert rules that enhances user experience by providing more filtering options, a cleaner UI, and reduced cognitive load. This update allows users to easily find alert rules using dropdowns for criteria such as Namespace, Label, Evaluation group, and Rule Source, while maintaining existing functionality for manual searches. The new feature is being rolled out in Grafana Cloud and will be available in the Grafana 12.3 release this October.
