Independent Alertmanager queues avoid issues with queue overflowing when one or more Alertmanager instances are unavailable which could result in lost alert notifications. The buffered queues are managed per AlertmanagerSet which are dynamically added/removed with service discovery or configuration reload. The following metrics now include an extra dimention for alertmanager label: - prometheus_notifications_dropped_total - prometheus_notifications_queue_capacity - prometheus_notifications_queue_length This change also includes the test from #14099 Closes #7676 Signed-off-by: Siavash Safi <siavash@cloudflare.com>
