High memory usage alert after upgrading to vSphere 6

Last night I upgraded my last ESX host from vSphere 5.5 to vSphere 6 update 2 + patches.

Ever since updating the VMware tools on my SQL server VM, I have been getting a "high virtual machine memory usage" alert constantly.  If I look at the guest, I see usage in the 24-25 GB range, with a little more on standby, but that only gets us to about 95%.  However on the VM Host charts and VM Summary, the memory has been shown as pegged at the max allocated to the VM: 32 GB.  I have attached screen shots.  Prior to the upgrade, it obviously didn't do this.  The active memory monitor was never accurate but also never pegged at the max.

Any advice or interpretation for this?

Thanks,
