Not sure if this is going to get answered but I'll give it a shot...
I updated the IOanalyzer appliance to openSUSE 12.2 and IOMeter/Dynamo version 1.1.0. (much better btw - you should officially update the appliance) but I'm having a slight issue with stats collection on the back end afterwards:

and more stuff like

Thu Mar 03 10:45:48 PST 2016 WARNING: Host X: insufficient counters on naa.XXX(need 16 has 15).
then I get errors on the results page like:
WARNING: Some Device counters were missing during stats collection.
Most likely it is due to a heavily loaded system on the ESX side
so that hostd service was unable to report counter values fast enough.
If majority of device stats are gone,
please consider reducing the load on the ESX that lost samples and try again.

... and no, it's not a performance issue. I'm running this in multiple 2x10 core xeon UCS blades with a XtremIO backend and the appliances are the only VMs on the hosts.
Would I have missed a package during the upgrade or is there something else I can check?
