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.
