attached mail follows:
One update: I no longer have any dependency on create-domain work as I
will implement it.
Also, since there are no comments yet, let's decide to go by the
approach of putting all monitoring information related to a module
within its config. [Let's aim for end of next week ...no guarantees :) ]
With this approach V3 module authors need to know specific tags to avail
of monitoring services offered by the infrastructure. (I hope this is
the same way Logging has been implemented)
