http://nagios.sourceforge.net/docs/1_0/macros.html details the macros
available and where they can be used. You're interested in the $ARGx$
macros. By example --


# 'check_http' command definition
define command{
        command_name    check_http
        command_line    $USER1$/check_http -p $ARG1$ $HOSTADDRESS
        }

# Service definition
define service{
        use                             generic-service
        host_name                       some_host
        service_description             some_description
        check_command                   check_http!2584
        }

More arguments can be passed with more '!'s --

command_line    $USER1$/check_http -p $ARG1$ -I $HOSTADDRESS -H $ARG2$
-wt $ARG3$ -ct $ARG4$ -to $ARG5$

check_command	check_http!2584!www.somesite.com!20!30!35

The above would translate to --

check_http -p 2584 -I aspapp1 -H www.somesite.com -wt 20 -ct 30 -to 35.
