Exception aggregator / classifier

Hi list,

I'm looking for a way to get a better resolution to unhandled exceptions. As of now I'm using the exception notifer plugin. It is nice to get an email when an exception occurs, but I would like to also have some kind of aggregation of exceptions, preferably classified, so I can see which exceptions are most frequent, etc. I'm imagining some kind of webbased tool which will classify and display exceptions.

Does anyone have any suggestions to such a tool? I can't seem to find anything on google. Or perhaps there's an even better solution which I simply haven't thought of.
