It's by design. VSI doesn't support VNXe performance monitoring, so it's not listed as known issue in release notes. Please refer to the product guide of Storage Viewer 5.3: Page 82(Storage Viewer provides the ability to view performance details for datastores and virtual disks that reside on EMC Symmetrix VMAX, Symmetrix VMAXe, and EMC VNX storage systems with statistics collection enabled.)
Hi  I have jsut installed VSI 5.3 and on a Vcenter Client The Vcenter in running V5.0 The storage system is a VNXe 3300 running Oe 2.1.0.14097 The Vsi plugin is configured and I can se details of the datastores.  We use both ISCSI and NFS datastores.  When i go into Vsphere client under datastores and selvect the EMC VSI TAB and click on the Performance buttom, it says loading for about a minute and then shows me the NFS details. It never gives me the option to start monitoring...  I have looked through the Prerequisites for version 5.3 and all should be good.  I have another setup similar where it works like a charm, in that setup the Storage is a VNX 5300 but VNXe shold be supported.  Any ideas are appreciated.
