The problem would appear to be with the on-demand macro you're using in
your check_command. I don't use check_cluster2 but a quick glance at the
documentation for it and on-demand macros leads me to believe that you
are using an incorrect form of the on-demand macro in the check_command.
If the service check_command above is accurate, is the
service_description for the service you're trying to check on all
machines really named 'Service'? Same for host_name. Are they really
host1 and host2. I can't imagine any reason that you would need to
obfuscate those and it's possibly confusing. I might help if you post a
host, service and service description as unedited as possible.

It might also help you to diagnose what nagios is really doing by seeing
what nagios would be running.

define command{
        command_name    check_service_cluster
        command_line    echo '$USER1$/check_cluster2 -s -l $ARG1$ -w
$ARG2$ -c $ARG3$ -d $arg4$'
}

After a check attempt you'll see the full command as nagios would have
run it on the command line in the GUI.
