 2. To poll the CM API for health status and update Nagios.
 
    Updating Nagios can happen in one of two ways:
    1.  Write to the Nagios "External Command File". (Default)
-       The command file is sepecified with the -c/--cmd-file parameter.

    2.  Use `send_nsca` to update Nagios via a NSCA daemon.

-       to specify the location of the send_nsca command, the NSCA server

    Currently, CM services and roles report a healthSummary which is used
    to determine a Nagios status code:
-
