I have a number of applications running on top of ASP.NET I want to monitor. The main things I care about are:

• Exceptions: We currently some custom code which will email us when an exception occurs. If the application is failing hard it will crash our outlook... I know (and use) elmah which partly solves the problem however it is still just a big table of exceptions with a pretty(ish) UI. I want something that makes sense of all of these exceptions (e.g. groups exceptions, alerts when new ones occur, tells me what the common ones are that I should fix, etc)

• Logging: We currently log to files which are then accessible via a shared folder which dev's grep & tail. Does anyone know of better ways of presenting this information. In an ideal world I want to associate it with exceptions.

• Performance: Request times, memory usage, cpu, etc. whatever stats I can get

I'm guessing this is probably going to be solved by a number of tools, has anyone got any suggestions?
