Along with the Spatial Utilisation you could monitor the data available in the Statistics/Data VC page.
This shows the packets going to each VC, along with discards,errors and queue overflow. These last three could be used to identify a struggling VC.
We are happy to help diagnose things if you get a capture, where there might be a problem.
Also if you have ideas about additional stats that would be helpful to you then please let us know. There's lots of stuff we can monitor but getting it displayed/logged in the best way for customers obviously works best with your feedback rather than our engineers best guess (not a complete guess we have worked with beta customers to get where we are today!) as we don't run networks ourselves.
That is an excellent set of graphs showing the relationship between the different utilization metrics (old & new) and throughput.
We can see that as the 'old' frame utilization goes >80% that the MU-MIMO kicks in. The new sector utilization metric still shows spare capacity only hitting around 60% as the throughput hits 141Mbps. Lovely.

I don't really need to go to 40mhz channels in the winter as most of the customers in this area are cottages but! In a 10mhz channel with the new 5ms timing I'm seeing great throughput.
We will have to start monitoring the new metrics like frUtlMedMumimoDownlinkSectorUtilization and report back. Either way we have one doing just short of 200Mbps tonight. AP is in a 30MHz channel.
That's some really nice throughput. Biggest number so far, thank you.
Although maybe we should do this in a bits/Hz way to make it fair :)
Some really good grouping size numbers too.
I expect throughput can, and will, be able to get higher than that though.
Look forward to seeing some addidtion MU-MIMO Utilization metrics.
Telemar,
Those Stats are averaged over the last minute (or 5 or 15 you can choose at top of page).
Was your sector busy at the time ?
If you have one window open to watch these stats and another window open to keep pressing the 'link test to multiple VCs' you should see some bigger numbers.
Still working on our new grafana panels, but heres one of our 450m's this is on 20mhz, shows last 24hr and is showing frame/mimo/throughput, forgive the drops on the throughput graph we have some snmp issues atm.
The fact that frameutilization low is returning 100% vs totalmimosectorutilization showing 70% is confusing the heck out of me, and is gonna make writing a networkwide report that covers 450 and 450m:S
You can see the new Utilization metrics can be more useful in tracking the throughput of the sector and it looks like you still have some headroom left.
I'm sorry it gets confusing tracking different metrics for different AP types though.
