Memory usage percent item prototype on proxmox ve http template

[asnrainbow]

Hello,

I've started to use the template to monitor my proxmox servers and its great except that i dont get RAM usage % just like CPU usage %
So i tried to make a new item prototype for the node item prototypes and its been unsuccessful so far

Im on Zabbix 7.0.6
my latest attempt looks like this:

I cloned the CPU prototype and modified it to look like this:

Name: Node [{#NODE.NAME}]: Memory, usage percent
Type: Calculated
Key: proxmox.node.memory.percent[{#NODE.NAME}]
Formula: last(/Proxmox VE by HTTP/proxmox.node.memused[{#NODE.NAME}]) / last(/Proxmox VE by HTTP/proxmox.node.memtotal[{#NODE.NAME}]) * 100
Units : %
Update Interval: 60s

Tags:
inherited:
class software
target proxmox

new:
Component Value memory
node {#NODE.NAME}

No Preprocessing

Im ending up with this error on latest data check: "Cannot evaluate function: item "/Proxmox VE by HTTP/proxmox.node.memused[pve]" does not exist at "last(/Proxmox VE by HTTP/proxmox.node.memused[pve]) / last(/Proxmox VE by HTTP/proxmox.node.memtotal[pve]) * 100"."

It seems i cant find the values im looking for and i don't know which path i should put in

Thank you if you take time to try and help me

ok i solved the issue changing the formula to this:
100 * last(//proxmox.node.memused[{#NODE.NAME}]) / last(//proxmox.node.memtotal[{#NODE.NAME}])
