Did you try with vms/{vm:id}/nics/{nic:id}/statistics? Note that
currently we have the following statistics available there:

  data.current.rx Receive data rate
  data.current.tx Transmit data rate
  errors.total.rx Total transmit errors
  errors.total.tx Total transmit errors

I guess that this isn't what you are looking for, but we don't have
anything else at the moment.

For disk IO you should take a look at
vms/{vm:id}/disks/{disk:id}/statistics. The collection of statistics
available there is the following:

  data.current.read Read data rate
  data.current.write Write data rate
  disk.read.latency Read latency
  disk.write.latency Write latency
  disk.flush.latency Flush latency

Does this cover your needs? If it doesn't I'd suggest that you open a
RFE to request adding additional statistics. Meanwhile you will have to
use other mechanisms to find the statistics that you need.
