A more flexible way of doing this so you don't have to create custom
check commands for every port would look like --

define command {
	command name check-tcp
	command_line $USER1$/check_tcp -H $HOSTADDRESS$ -p $ARG1$
	}

define host {
	host_name foo
	yada yada
	yada yada
	address 127.0.0.1
	}

define service {
	host_name foo
	yada yada
	yada yada
	check_command check_tcp!15004
	}
