Customizing reports via the weeb interface

Is there a way to setup the reports so that you can do a search for specific time frames, alerts and nodes through the web interface instead of on the server?  If a Customer wants to see his CPU threshold alerts for the past month, for one device, how can they do it?

Also how can a report be done on specific alerts that were sent out over a specific time frame> Take the above example and look for the number of times a threshold was exceeded on a specific node.

How can this be done?
