Grafana Alerting: Searching for Grafana alerts just got faster, easier, and more accurate

Grafana Alerting enhances the ability of users to manage alert rules and workflows within Grafana by allowing them to create and customize rules and link them to Grafana panels across various data sources like Prometheus, Grafana Mimir, and Grafana Loki. The platform faced challenges due to the complexity and volume of managing numerous alert rules, prompting the development of a new search engine that streamlines finding specific alerts by utilizing a simple query language inspired by GitHub's search field. This new search engine leverages a custom grammar parser built with Lezer, enabling robust filtering capabilities through a key-value pattern to improve the search experience without the limitations of regular expressions. The search engine supports free-form search, maintains a stable order of filters, and features a UI that syncs with search expressions, ultimately facilitating the efficient management of complex alerting workflows to enhance system reliability and uptime.
