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
