check_zone.pl

Usage:
check_zone.pl [-v[v]] domain

For command:
define command{
command_name check_zone
command_line /usr/bin/perl $USER1$/check_zone.pl $ARG1$
}

Note the use of /usr/bin/perl in front of the command - this is because check_zone.pl is not currently (as of 4/12/2009) compatible with ePN.

For service definition (this checks example.com):

define service {
host_name ahost
service_description ZONES
check_command check_zone!example.com
....
}

ahost could be no-host (or a host assigned the check_command check_dummy) since the check is not dependent on the host it is assigned to in any way (e.g. it doesn't use $HOSTADDRESS$).
