I have a device that is no showing discovered OID that I expect to see.
Release : 20.3
Component : UIM - SNMPCOLLECTOR
This could be a case where template that you are using does not actually have a filter created for the OIDs you are trying to monitor.
-open https://devicesupport.broadcom.com/
-Supported Vendors > IBM > IBM Data Power Generic > System Utilization Information > Host
-make a copy of the default template, or if you are using a copy of the default, you will then find that in reverse:
Host > System Utilization Information
Under there you can add a filter to turn on:
CPUUtilizationLastHour
UtilizationMemory
-save the template
