Query Explanation

The query takes the current time (time()) and subtracts the latest evaluation timestamp of each Thanos rule group (prometheus_rule_group_last_evaluation_timestamp_seconds), then checks if that delay is greater than 10 × the group's configured evaluation interval (prometheus_rule_group_interval_seconds). The alert fires when any rule group has not run for at least ten of its expected intervals, indicating the group is stalled or not being evaluated.
