Heng, I maybe wrong as the latest code is somewhat different from the one I followed last time, but it looks like the information is update at line 440 in nova/nova/compute/resource_tracker.py.

Any help will be appreciated, please let me know the exact location (file, function, etc.) and how I can mimc that to modify my own new field in the compute_nodes table. Thanks in advance.
