ESX Available CPU & Memory on Dashboard Graph

I am trying to setup a dashboard where it shows ESX hosts and their available CPU and Memory. I tried doing server stats, but that brings in all the VMs on a host. I just want to see CPU and Memory of the actual ESXi Host (ucs blades).

Have you tried adding the ESXi hosts directly?

Yes. There is no good graph I could find. I tried server stats from available widgets but that returned all the server stats from all vms on host as well.
