(No output returned from host check)

[Albert Whale]

Replying to my own posting for the sake of the archive (in case this 
occurs to anyone else).

The Host Check function is defined for the host when it is defined.  You 
can review the current setting/definition by selecting the View Config 
side panel menu and then selecting the Hosts drop-down option.  The 
current Host Check Command for all hosts is displayed.  Verify that the 
'Host Check Command' is accurate, and executable by the Nagios user.

In my situation, I was deploying the nrpe plugin, along with NagiosSQL 
configuration guide.  It was a late night, and the host check setting 
was changed at some point in time earlier.

Hope that this is useful to someone else in the future.
