Likitha Shetty reopened CLOUDSTACK-1868:
----------------------------------------
Assignee: Likitha Shetty (was: Sateesh Chodapuneedi)
In CloudStack we obtain the network statistics using 2 network metrics
'net.received.average' and 'net.transmitted.average'. And these metrics are
collected at level 2.
Hence this error is only reproducible if we update the vCenter server setting
'Statistics Level' to 2. By default the Statistics Level in vCenter Server is
set to Level 1 for each performance metric.

> We see bunch of these in the log files of CloudStack. Looks like the
> GetVmStatsCommand crash with a Null pointer exception. We don't think it's
> permission related since our CS user on vSphere can see all performance and
> VM statistics using the vSphere client.
