ESX - Calculate Total Memory Allocated to VMs

[Sven Kodali]

Appreciate if someone can help with this as I am at my wit's end...

The organization I work for provides VM hosting on VCenter / ESX platform. We charge per usage of data, memory CPU etc.

Is there an item I can create that calculates the total amount of RAM assigned to all VMs on the host? Say if there are 10 VMs, I need the total amount of RAM allocated for those. This has to take into account any other VMs that are added without having to modify the formula.

Until now I have used the vmware.hv.memory.used, but it is not providing the correct information for me. I wonder if this is because it is also taking into account the memory used by the host itself?

You might be right that vmware.hv.memory.used value contains the memory used by ESX host.
I would suggest to create the calculated item in which you could sum up the vm sizes. Try the one below:

sum(vmware.vm.memory.size[,vmid])

Thanks for your suggestion, is there a way to include all VMs without specifying each one?
