Hobbit server itself not reporting most services

My Hobbit server is only reporting bbd, conn, http, info,smtp,ssh and
trends.  At one point it reported the others like cpu, disk, memory, etc...
but at some point in the last few weeks I noticed that it is no longer
reporting the status of those.  Nothing I know of has changed and there is
nothing I can see in the config files that should be preventing it from
reporting.
 
Any ideas what is wrong?
 
Thanks,
Jason
