Guys, I've attached 2 health reports from AMP. I need to understand what is considered high values/thresholds so I can determien the issues:
What are high noise values? Aruba says set alerting thresholds at -80dBm. So is >-90 high (problematic) and -60 considered good?
Same for "high number of clients". Aruba says set alerting thresholds at >15. need more clairity on this.
same is true for High Channel utilization. is >75% bad and >50% good?
Can you explaing the above and look over the health reports and point out obvious concerns and provide clairty? thxxs much

Thresholds are specific to environments, and is relative.. There are some users who have environments where there is high density and channel utilization climbs to 50%, but the network is working fine. You need to baseline when the network is working, to understand what your individual thresholds are. That last statement is a huge generalization, but that is the way it is... If network is well designed, the utilization can climb to 50 or 60%, but it can tolerate it, and your users are fine.

The value comes from checking your networks' health on a day when everything is fine, so you can see what fine looks like, then checking when folks are complaining to see what "not-fine" looks like.
Once you've got a good feel for fine and not-fine, you can tune your alerts.
