The query counts how many times the process_start_time_seconds metric for Loki processes changes in the past 15 minutes, and fires when this count is greater than 2 – meaning a Loki instance has been restarted more than twice within that window. Thus, the alert triggers if any Loki target shows three or more restarts in a 15‑minute period.
