Description
Hello
For some reason observium doesn’t display graphs for some interfaces in cisco nexus devices.
I can see everything up to Ethernet110/1/48 and nothing after that in observium. But in other monitoring software there is no such issue.
I have some phantom FEX interfaces 114/1/1-48, 164/1/1-164/1/32, 198/1/1-198/1/16 and 199/1/1-199/1/16 that I cannot get rid of.
It seems that the problem starts from from where the phantom interfaces first start (Eth114/1/1), but I am not sure if these have anything to do with it.
Could you please help me with this issue?
Please see the screenshots and files also

As already discussed in Discord, this is firmware issue.
Device do not report counters for this interfaces in snmpwalks:
$ grep '\.528614912 ' putty.log
ifIndex.528614912 = 528614912

(I rechecked snmpdump and there same - no counters)

this is which command used for polling interfaces (your auth is hidden by ***)
