Specification of nova-diagnostics



I've been trying to implement the nova-diagnostics command  for libvirt.
I'm using the devstack installation on ubuntu 12.04. So far i've managed to
gather information regarding CPU, IO (network and disks). The memory
reading only works with the virsh command and does not report the actual
memory usage.  As pointed out to me previously, i've been looking at the
implementation of nova-diagnostics for the xenapi in order to try and
figure out how to supply the data back to openstack. However, i can not
make any sense of it. All i know is that it returns a set of keys with
values, which i suppose represent the values of the readings. What i wish
to know is if there's any document or specification which i can read which
defines what nova-diagnostics should return and under what format.
