> Currently the MetricsConnection metrics are only exposed via jmx. This is not
> very easy to deal with on the client side. In our environment we have 10s of
> thousands of client instances and we do not expose a jmx port. If we did,
> it'd be painful to try fetching from so many (and constantly changing)
> instances.
> Many environments have their own monitoring stack and their own way of
> shipping deployables metrics to their monitoring. We should provide a way to
> get access to these metrics within the process. It's possible (but extremely
> cumbersome) to query jmx beans from within the process. We did this in my
> environment and I would recommend against it. Let's provide direct access to
> the metrics.
> I think we probably want to keep MetricsConnection IA.Private, but maybe we
> can create a new MetricsConnectionSnapshot and provide a getter on the
> Connection/AsyncConnection.
