Attempting to trigger an alarm when a metric stops ingesting (such as a missing heartbeat) using standard Alarm functions within Metric Groups fails to fire.
Because DXO2 relies on event-driven monitoring, the system requires an incoming data event to trigger an alarm evaluation cycle. When metric ingestion ceases completely, the evaluation engine remains inactive, preventing the missing-metric alarm from triggering.
