This is fairly simple; you may want to look at the documentation for
object syntax:

http://nagios.sourceforge.net/docs/2_0/

First create a check command that contain the actual command-line and
arguments. Then create an active service definition that use that check
command, and set the check interval to the interval to what you want to
run the script at.

Please keep in mind however that Nagios does not guarantee your script
will be run exactly at the defined interval. This can be especially true
for huge setups if many hosts are down or if Nagios is misconfigured. I
wouldn't use it as a crontab replacement. If you want the results of
your crontabs in nagios I'd rather do passive monitoring with NSCA.

Also note that anything run by Nagios is run as user nagios, so if your
scripts needs root privileges you will need to use sudo.
