Memory Utilization in Custom PDF Report

I've pretty new to the custom reports that can be sent reoccuring via email and could use some help.  One challenge I have is reporting on memory utilization for a VM guest.  In the 6.7.1 version of vFoglight there was nice update to the memory utilization view on the Summary Tab for any VM guest in the environment.  See below. 

But when I go into my custom report and try to get this same view displayed I don't see an option for VM Guest Memory Utilization.  There are options for allocated, consumed, reserved and so on, but no guest utilization like in the summary tab.  I have an option for the host memory utilization but obviously this only reports on the small fraction of memory the VM guest uses for the entire available memory on the host.  Is there a way to add VM guest memory utilization to a custom report?
