Decoding Identifi DCS stats

[James_A]

A teacher reported her class was having trouble streaming video, I checked /proc/dcs on the AP3915i and could see there was high utilsation:
R0 upt relt nfAvg utilAvg txAvg rxSelf rxAvg nfRt utilRt txRt
R1 upt relt nfAvg utilAvg txAvg rxSelf rxAvg nfRt utilRt txRt
R0 701186 -2777 -87 60 55 2 5 -92 86 81
R1 701186 -2777 -84 9 5 2 2 -87 9 5
R0 701246 -2717 -87 71 67 2 4 -91 86 83
R1 701246 -2717 -84 8 5 2 2 -87 9 5
R0 701306 -2657 -87 44 41 1 3 -91 56 51
R1 701306 -2657 -84 8 5 2 2 -87 8 5
R0 701366 -2597 -87 26 24 1 3 -91 15 12
R1 701366 -2597 -84 9 5 2 2 -87 9 6
Some of these columns I can work out - noisefloor, utilisation, transmit percentages, but what are the Rt columns about? 10.41.08, I see the AP3825i has similar stats, but the AP3710i doesn't (only nf0 rtChRegUtil0 rtChTxUtil0 nf1 rtChRegUtil1 rtChTxUtil1).

Next question - are any of these exported over SNMP? I've previously been graphing apPerfRadioCurrentChannelUtilization but that is showing as 0 for the time above.

Hmm, .33 isn't what I want, that's just about neighbouring APs and collisions. Maybe if I add up .35 and .37 that will be more what I'm looking

Hi James

I don't think these stats will perfectly align with the AP's DCS file, but the main OID I've come across is in this article: https://gtacknowledge.extremenetworks.com/articles/Q_A/What-is-DCS-channel-occupancy-threshold-and-w...

I think .31 gives DCS noise as well.

If this isn't what you're looking for you might want to open a case so we can investigate further.
