VMWare vCenter - Virtual Machine partitions information and utilization

I know vCenter have API get information about local file system on the guest vm running on ESXi host (as long as VMWare Tools are installed on vm):

  • capacity (in bytes)
  • freeSpace (in bytes)
  • diskPath (eg. C:\ for Win or / for *nix)
  • fileSystemType (eg. ext3, NTFS, etc...)

Ref #1: https://vdc-download.vmware.com/vmwb-repository/dcr-public/184bb3ba-6fa8-4574-a767-d0c96e2a38f4/ba94...

Ref #2: https://developer.vmware.com/apis/vsphere-automation/latest/vcenter/api/vcenter/vm/vm/guest/local-fi...

I believe RVTools, and some monitoring tools are using this specific api to grab info about local file system on the guest vm.

 

So far I was able to find metrics regarding datastore usage. This is fine, but equally important metric is local disk utilization of the guest vm.

Which metric is responsible for getting this info in VMWare or VMWare Metrics AddOns?

If none of the listed. Is there a way to customize VMW or VMWmetrics AddOns to grab this crucial information about VMs from vCenter?

Perhaps I should look elsewhere - I mean different App/AddOn?
