 * Host based threshold alerts      - Like the system level alert, it's an alert that happens more than x times per host.

 * The advantage and reason for having host based alerts is that it allows you to target ticket generation for a specific host
 * and more importantly, to be able to have a separate re-alert cycles for that very same message as there can be similar messages
