ASP.NET 2.0 Health Monitoring is Goodness

The new Health Monitoring framwork in ASP.NET 2.0 is very cool. Besides that ASP.NET itself uses it to emit all kinds of useful status information, you can build your own WebException classes and connect them via configuration to the EventLog, WMI, Emails a.s.o.

I am particularly impressed with the information that ASP.NET puts in there by default (in addition to whatever custom info you pass on to the the Exception).

An example of an WebException in the EventLog (special attention to process and thread information and security contexts as well as trust level). nice
