I'm looking for a way to decide how to handle an alert based on the status of a custom poller or custom property. For example don't alert on network devices going down if the UPS driving them had lost power. I could determine the power event by the last value of the custom poller for the UPS or I could use the SNMP trap the UPS sends when it goes on battery to update a custom property to a specific value.
Anyone have other ideas on how this could be handled? I'm looking at an external program call now to update the custom property via a SQL UPDATE statement to the DB.
