Using Nagios to monitor "service-less" hosts

[Tedman Eng]

Host checks are not actively scheduled in normal operation.

You could go months without requiring a host check, and the status age of
the host check will show something like 81 days for example.

If you see recent host checks, then that means there was a service problem
and Nagios wanted to be sure it wasn't the host.

Perhaps if you thought of "host check" as "network link status", it would
make the distinction more clear.
