Hi, when I wanted to set my Polling Parameters, I couldn't select a device. there where none shown.
I imported the device from DCR, and however 1 is still in questioned state, which I think is because its cluster managed suite, all the other devices are known.
What could be the problem?
This is normal. You're not expected to see any devices here. Polling parameters are defined on a device group basis. If you want to adjust the polling parameters for only a subset of devices, you will need to configure one of the Customizable Groups for that.
