Reloading every 5 minutes is not advised. You only want to reload when  
you've made changes to the DB.

However, you've basically described Opsview (http://opsview.com): do  
configuration changes in the database, then generate Nagios  
configuration by kicking off a reload. Bonus points: Opsview will also  
generate the configurations on any distributed slave systems at the  
same time!
