Hi Vladimir,
I find the query stats strange. If you count on the answers, why aren't
they answer stats? And why aren't the other flags counted. I for one would
be interested in AD.
I think the prefetch stats need some more definition. Right now I can't see
a real use. I would like to see how many queries are considered for
prefetch (is this prefetch.queue?) and the total amount of prefetches done.
For the RPZ I think it would be very interesting to see which RPZ and
action combination was hit how many times.
Maybe you could look at pihole 
https://pi-hole.net/ these people have a
nice dashboard and good statistics for their DNS service.

 To be clear, this is done as counting answers from knot-resolver, just
 like for stats.list(), but in correct setup these properties should be
 exactly the same as in the corresponding requests.
