No. I think that was question on some conference, DNS-OARC perhaps.
The proposal was what if bind9, unbound, knot-resolver and pdns-recursor
could create the same format for their statistics. So prometheus could
have only one statistics parser code. It might be exported to different
path in filesystem and that should be enough. Only path and content
should be different for different services. Format should ideally stay
compatible. Then it would require less code as glue between statistics
dashboards used and the DNS service itself.
I think such common format would be great. I would prefer something json
based. I can describe only bind9 and unbound statistics. Their format is
very different, although quite a lot numbers could be similar.
This is main statistics refactoring issue at bind9

I am not sure where exactly did they talk about requirements for a new
format, sorry. I think it was mentioned after some talk at some OARC
recording, but do not remember which one.

Such topic were recently started also on BIND9. If you can document
what different statistics is in use now, it might be used to create
one common format used by any DNS service. It is silly when each have
different format, which can be transformed by some external module
into format common on some monitoring service.
I am not sure unbound should offer it on HTTP service socket
Do you mean one of these:
unbound-control stats_noreset
unbound-control stats

Yes. It would be nice, if it could serve only subtree. Hmm, would be
cool, if it could serve CH answer.num.stats. TXT? query? Although that
would need some ACL protection.
The then you want to put this into some graph usually. That needs to
pick specific fields from these and map them to some graph lines. Every
implemetation seems to have very different statistics output format.
Systemd people like Varlink format. That could be usable too.
