OK, good.

Bzzzt.  Here's where it's incorrect.

check_nrpe only checks the status of the NRPE daemon on the remote
end.  You need to use NRPE on the remote end to invoke your
check_wadmin test.

So, on your Nagios server, you need to set the command_line for the
check_wadmin command to something like:

$USER1$/check_nrpe -H $HOSTADDRESS$ -c check_wadmin


$USER1$
^^^^^^^ The path to your local plugins (on the Nagios server)

        check_nrpe
        ^^^^^^^^^^ Need to use check_nrpe to check the command on the
                   remote host

                   -H $HOSTADDRESS$
                   ^^^^^^^^^^^^^^^^ What host to check

                                     -c check_wadmin
                                     ^^^^^^^^^^^^^^^ What command to
                                                    run *ON THE
                                                    REMOTE HOST*

NRPE only allows you to run plugins designed to be local-only on
a remote system.  You need to tell it *what* to run, and *how*
to run it.
