I have upgraded to SAM 6.6.1 on Orion platform 2018.2 HF3
I do not have NPM. Only SAM.
I have a custom SNMP monitor application that I've been using to monitor my UPS devices. I was really happy to see the new Power Control Unit Status in the upgrade. At least I was happy for a few minutes.
The PCU is showing initial data when it first discovers an APC UPS. After that it never updates the data.
I removed UPS from List Resources. Then went back in and added it again. Same thing. It displays accurate data on first discovery. Then it never updates that data. My custom SNMP application is still showing all current data.
