Release : 20.1
Component : UIM - SNMPCOLLECTOR 3.*, 4.*
On the snmpcollector hub, for alarms to be used, nas, baseline_engine, or alarm_enrichment are needed to run on the hub.
If nas, baseline_engine, or alarm_enrichment are deactivated, this exact issue will occur.
In the snmpcollector hub ensure that the following probes are installed and active:
nas
baseline_engine
alarm_enrichment
*This is a requirement if alarms need to be enabled.
