Could you help me understanding of my device status correctly :
I was looking at my device status in PANORAMA's beautiful featrure called "Deviating devices" list. I couldn't quite understand why it is reporting some of my PA devices as deviating from Baseline though it's not even close to the threshold values. for example it's reporting a device as deviating when it's memory is at 27%. Sometimes it's red even for the connections count 2.
Could you please help me understanding, if you come across this issue.

So I have seen the same issue. I see that my primary HA firewall pair is listed, and the active firewall is deviating, but all of the metrics are low... 7k sessions, 22% cpu, 208 logs/sec. It's very strange.

As per my understanding if firewall sees increases in traffic as compare to previous baseline even though threshold is not reached it show it as red.
Lets see if someone chimes in about this behaviour.

Hi , it's a bit of a slow reply I realise, but I have just been looking at how many warnings we are logging and it seems to me that the baselining calculation doesn't allow for variations caused by night time and weekend lulls. The little graph it displays shows my supposedly deviating stats are following a fairly normal pattern, but the baseline is way too low for daytime activity levels. I can only assume that's because it's an average over all time and the variation between my day and night is huge, as I would guess it is for most people. It uses some standard deviation to calculate a tolerance, but that's far too conservative.
Take an example of my logging rate, to the human eye you can see it's sticking to the normal pattern but because the rate drops to the low 100's overnight, the 2,000 rate in the daytime is way outside the baseline and tolerance. Weekends just add to that imbalance.
Palo, can you change the algorithm to take into account time of day variations? I'm no mathmetician so don't know how, but at teh moment I am just having to ignore/filter out the deviating device logs as they trigger all the time.

I can update, this has been accepted by Palo as a feature update, so don't hold your breath, but we should see a change at some point.

2,5 years later and still the issue present.
