Filter Collector Events?

Over the years I have run across relatively few customers who leverage the part of the AR Collector that gathers the contents of the Admin Service event log.

Historically, one of the challenges with this component is that the events take up a huge amount of storage and over time, if not purged periodically, the database will become less and less usable for reporting.

In past engagements, I have created a purge query to clean out old events but I am just curious if anyone ever built a query to get rid of "unwanted" events - for example, innocuous attribute changes.  This would be done with a view to "filtering" down the contents of the database to important things like object creates and deletes for example.

'Look foward to your insights.
