> The JournalNode should expose some basic metrics through the usual interface. In particular:
> - the writer epoch, accepted epoch,
> - the last written transaction ID and last committed txid (which may be newer in case
that it's in the process of catching up)
> - latency information for how long the syncs are taking
> Please feel free to suggest others that come to mind.
