Just one thought - not a requirement at all for you to change the PR, but just something that might make a change like this easier in the future.

Very quickly glanced and lgtm, talked with @eberger727 and it would be nice to include tags on the messages and token transfer counters to keep track of number of messages / transfers btwn pairs of members i.e. to and from tags on each counter.

Not a requirement for this massive improvement around metrics, but will open a follow up issue for it.
