As we've talked, I will do some research on this topic and will try to prototype something.

This may need a bit of investigation to nail down requirements. At a minimum:

Stats per identity (or pair of identities) for things such as:

Total connections

Failed connections

Active Connections

Many other things

See Envoy’s upstream cluster stats for some examples of what we want to track.

Jacek is prototyping the type of metrics to be collected.

Best to submit a PR with instrumentation and minimal metrics to kickstart the discussion.

The task requires more than stats obj, @jewertow would like to unassign him for now.

Should we close this or continue to track work for inbound stats here?

[howardjohn]

I think we can use this to track future stats

[SkyfireFrancisZ]

will have PR out later today

Basic stats are implemented
