Ok, I looked at all possible causes from all angles I can think off, but I couldn't find anything conclusive.
In vSphere 4.1 performance counters for NFS datastores were introduced.
See What’s New in vSphere 4.1, and I quote "NFS statistics are now available in vCenter Server performance charts, ..."
So the counters should be there.
The only point we could still check is the actual version of the ESX(i) servers that have the datastore(s) connected ?
Are these all ESX(i) 4.1 or higher versions, or could there be a lower version/build in there ?

You mention that you have the problem of missing performance metrics only for some datastores.
Can you can confirm that you can see performance data for all the datastores in the vSphere Client for the historical intervals (last day/last week...)
And you do mean this performance graph I assume ?
