Monitoring Non-routable Address Space

Greetings,

I have hobbit up and monitoring correctly quite a number of systems. However, today I am trying to monitor a system in non-routable address space and it does absolutely nothing. The system name does not even come up in the list of systems to be monitored. The hobbit server is in the same address space and can ping the system I want to monitor. I am at a loss for what is happening.....

Thoughts.
