I've been told by GTAC that a lot of those snmptraps listed in the oneview reports are not enabled for typical collection. I was told that the ap channel utilization trap is only collected for VENUES. Not sure what "VENUES" means exactly.
If you go to oneview>administration>diagnostics (change the level to diagnostics in the top left)>historical statistics collector>statistics collection targets
Then filter the Type column for "AP", you will see all the ap's that netsight has collected data from. select an Active entry and show details. You will see all of the stats that oneview is collecting for that device. On my AP's, it is only collection 14 traps, even though there are so many more listed in the oneview reports.
This is been a major let down for me, as i haven't been able to report on things like historical channel utilization and DCS noise, even though the traps are available.
