Sorry about not joining your weekly calls. There are just too MP components to stay intimate with all of them all of the time. And, you run such a tight ship, Heiko, that you don't need any of my assistance... :-) Seriously though, Alasdair and I were just talking about furthering the use of Metrics the other day...
How about integrating Metrics with some of the technologies? (Optionally, of course.) For example, what about monitoring the use of the Retry logic in Fault Tolerance? Providing metrics on how often fallback processing is invoked. That type of thing. I suppose you could say that this should be part of the FT effort (or whatever technology you are targeting), but it would probably require some pushing and convincing by this Metrics team.
