I've enabled network discovery for the first time in awhile (now that it doesn't count against your licensed devices), and I'm noticing that alerts are functioning on these devices.
I'm not sure yet if they are counting against my licenses yet (I'll have to see if the number changes drastically) but discovered devices shouldn't be alerting or even showing up as red until I move them into another group, correct?
You do not state what build of KNM your using ?
I just updated to KNM v5 Build 9735 this morning, and I may be ok now. I'll see if I can schedule some more network discoveries and try to reproduce it.
