Statistics per view: toggle views on the Statistics page

Answers, result codes, record types, zones, blocking, rate limiting and the top lists are also counted per view, from named's response log. The Statistics page has a toggle per view with All and None, remembered per browser; jarl stats --view and ?views= on the API. named's own counters stay for the whole server, and the page says so.
