Possible to Monitor only Uncaught Exceptions?

Question

Is it possible to configure AI to only monitor uncaught exceptions? 
One of my clients has a legacy site which 301 redirects a bunch of traffic.  This site still gets significant traffic from crawlers, and we use a 404 handler on the new site to intelligently Response.RedirectPermanent these requests to the correct
new page.  However, AI sees each one of these page hits as an exception.  Is there any way to configure AI to only monitor uncaught exceptions?

Hello RNCRyan,
If you are using MMA - there is an entry in collection plan that you can change for this matter (it enables/disables reporting of handled exceptions):
<EnableAllExceptions>true</EnableAllExceptions>
Default collection plan has "true" here, so you should have your custom collection plan with this setting switched to false.
In case of On-Premises or IaaS installation you can specify your collection plan in Start-WebApplicationMonitoring command:
Start-WebApplicationMonitoring -Name {YourWebApplicationName} -Mode Custom -CollectionPlan {PathToCustomCollectionPlan} -OutputChannel Cloud
If it's Windows Azure PaaS, then you should place your collection plan under the applicaiton root (side-by-side with web.config) before deployment. File name should be like: monitoring.collectionplan.config.
