Source note · Unified CM RTMT alerts and monitoring
The RTMT backend checks service status every 30 seconds by default, so a service that goes down and recovers within that period may not raise CriticalServiceDown.
Checked 2026-09-25
If service goes down and comes back up within that period, CriticalServiceDown alert may not be generated.
