vm hosts calulated items

[jvillain]

Hello:

I would like to add a couple of calculated items to my "Template Virt VMware Hypervisor" template. The items are memory and cpu as averages. For memory some thing like this.


(vmware.hv.memory.used[<url>,<uuid>]/vmware.hv.memory[<url>,<uuid>])*100

I have also tried

(last("vmware.hv.memory.used[<url>,<uuid>")/last("vmware.hv.memory[<url>,<uuid>]"))*100

When I try to do either I get the message Incorrect key: "Invalid item key format.".

I am using zabbix 2.2.1

Can any one tell me what I am doing wrong? Thank you.

This is my formula for Calculated Item in Template Virt VMware Guest.
I'm calculating how much memory guest OS used out from configured amount of memory

100*last("vmware.vm.memory.size.usage.guest[{$URL},{HOST.HOST}]")/last("vmware.vm.memory.size[{$URL},{HOST.HOST}]")

Thank you aib. Can you tell me what you used for your key?

This is my Item configuration screen
Key: vmware.vm.memory.size.usage.guest.percent[{$URL},{HOST.HOST}]
