What kind of monitoring do you need?  If it's just a matter of finding
out that the controllers are still alive, then the existing "nb_cfg"
column in Chassis can suffice.  When neutron wants to check on the
controllers, it can increment nb_cfg in NB_Global and then see which
controllers update nb_cfg in Chassis in response.
