I would suspect the CPU, which with 75% is on the high side (and the 'good' is 'only at 68%' which is high in my view).
You can reach out to Aruba support if you need this confirmed. As well, they can investigate where this high-CPU is coming from and if it is normal and acceptable; which I would be more worried about. I checked my APs and they are in the 0-20% range for CPU.

Can you share the metrics for poor health status? If you 'mouse-over' the graph you can see the metrics:

There should be a difference in those metrics between good and poor, and much in Central now is dynamic so the Good and Poor could be 'compared to others' which makes there might not be a generic formula to calculate the score.

Hi
I have an AP that Health status is going from good to poor multiple times in a day (please see attached)
I also got reports that client are getting disconnected
Looking at the details of the CPU, Memory, Noise floor, and utilization of the AP when it is good or poor
I dont see much if a difference
Anyone know how the Health Status is calculated ?
On Average only 8 clients connected to it, (IAP 207 running 8.5.0.5_73491)
thank you
