I'm seeing the same problem on a new Smart-UPS X 2000 whilst all my existing 5000s are reporting properly with both the <Power Control Unit Status> widget and the <APC UPS> SAM template.
I think I'll raise a ticket.
support case #00217809 raised
I believe UPS polling is done via Cortex. If SAM template's correct, then there's probably a problem in the Cortex. Are you on the latest Orion version? And yes, I agree - open a ticket for that.
My ticket recommended upgrading to the latest level. I've taken mine to NPM 12.3 and have applied the latest HotFix6 bundle. It didn't immediately work and a List Resources did not show the new APC as a valid resource. I deleted the APC UPS node from Orion and re-added it. It immediately found the APC resource & all is well.
