The stacktrace is important, it should be alarming about the "getAlarms" methods for this to be accurate.

Deploying ems and alarm_routing_service will cause no changes in how alarms are routed, but the null pointer exception will be avoided.



Unified Infrastructure Manager 8.4, including Service Pack 1 and 2






1. Deploy ems to the primary hub


2. Deploy alarm_routing_service to primary hub

3. Refresh the screen - the issue should be resolved.
