vSphere 6 U1 and vROps 6.2 VM Packet Loss

Have a client with a brand new vSphere 6 U1 deployment with vROps 6.2 and have VM's reporting high dropped packet % in the Guest.  I have seen this with 6.0 with the fix in 6.1 and also have seen KB's related to patches that were required on 5.1/5.5.

I am pretty sure the reported packet drop % is bogus as it is as high as 50% on some VM's and they are running normal.  It is a bummer as I would typically create dashboards with KPI's that are meaningful for a VM such as CPU Ready, Co-Stop, Disk Latency and Dropped Packets %.

Anyone else have this problem?

Here is basically a KB explaining that it is broken again with vSphere 6 after being patched/fixed in 5.1/5.5: 

VMware KB: vCenter Server 5.1/5.5/6.0 performance charts report dropped network packets

What gives? Why is this a common re-occurring problem?

Yes you are right, there is a known issue with ESX 6 that vROps would report received packet loss on VMs. I am currently experiencing this and yes there are measures you can take to fix this using esxtop but I am not to familiar with it as I have another team working on this at my workplace.
