ASP.NET Health Monitoring doesn't log inner exception stack trace

This can be a problem, especially when an ObjectDataSource starts throwing exceptions. The stack trace looks the same because of the way the methods are invoked (via reflection) - you end up with a stack trace for a TargetInvocationException, which basically says, "I used reflection to invoke some method, and it threw an exception. See the inner exception for details."

ASP.NET's health monitoring system does list the inner exceptions (apparently up to a maximum depth of two, from spelunking the code with reflector), but it does not emit the stack traces for these exceptions, which would be really helpful. I've spent some time this morning trying to figure out how I'd customize things to emit this, and it looks like what I'd have to do is catch the exception and generate a custom WebEvent that overrides ToString(bool, bool) and does everything that WebRequestErrorEvent does, but also generate the inner stack trace.

That seems a bit ugly. A search for "ASP.NET web event inner exception stack trace" yielded no interesting results, so if you've dealt with this and have a cleaner solution, let me know. I'll post my solution once I get it worked out.

UPDATE: I ended up writing a custom email provider.
