Are you asking how is it possible to monitor the local storage on a VMWare host? It can be done via the poll for VMWare option as well as enabling SNMP on the host server. Either way should get you the local storage for the host. If you are referring the to VM Guest, then depending on the OS, you can use SNMP for this information and it will give you the "local" storage the guest is using. Not really sure though what you are asking here.
