VMware VM CPU Usage % Calculation

[X3n0]

Hi guys,

I'm trying to create an item by calculating the CPU Usage in Percentage (%) for the template VM VMware Guests.

I cannot use vmware.vm.cpu.perfcounter() 'cause I have too many different machines to monitor and couldn't turn-on CPU performance counters per each one.

I alredy tried calculating it using vmware.vm.cpu.usage[{$URL},{HOST.HOST}] * vmware.hv.hw.cpu.freq[{$URL},{HOST.HOST}] / vmware.vm.cpu.num[{$URL},{HOST.HOST}] but it seems like that is not possible to include an "Hypervisor's key" inside a VM Guest template.
I even tried inserting the item for VM's HV Name instead of the UUID for the frequency's item -> vmware.hv.hw.cpu.freq[{$URL},"vmware.vm.hv.name[{$URL},{HOST.HOST}]"].

It seems there's no way to make it work.


Do you know if there any other ways to obtain the CPU Usage in Percentage?

Try to follow the guide from https://bestmonitoringtools.com/vmwa...er-vm-vsphere/

Have you solved? When I tried to use this key vmware.vm.perfcounter[{$VMWARE.URL},{HOST.HOST},”cpu/usage[average]”] but i receive an error:

Invalid key "vmware.vm.perfcounter[{$VMWARE.URL},{$HOST.HOST},”cpu/usage[average]”]" for item "VMware: % CPU Avarage Calc" on "VMware Guest": incorrect syntax near "”]"

It's this the correct way?

Thakns in advance

I know it is too late to replay but the problem might be in quote symbol if you copy/paste key expression from internet.

If you can't use vmware.vm.cpu.perfcounter(), try this formula for CPU usage percentage:
perl
(vmware.vm.cpu.usage[{$URL},{HOST.HOST}] * 100) / (vmware.vm.cpu.num[{$URL},{HOST.HOST}] * vmware.hv.hw.cpu.freq[{$URL},{HOST.HOST}])
Ensure VMware Tools is installed for better metrics, or consider using custom scripts inside the VMs for direct CPU usage data.
