How to stop unbound reporting any statistics?

[Michael Grimm]

Hi,

I do have the following (default) set in unbound.conf:

	# print statistics to the log (for every thread) every N seconds.
	# Set to "" or 0 to disable. Default is disabled.
	statistics-interval: 0

But: Whenever I do stop unbound, a lot of statistics are reported like:

	<user.info>: stopping /usr/local/etc/rc.d/unbound
	<daemon.info> unbound[12792]: [12792:0] info: service stopped (unbound 1.10.1).
	<daemon.info> unbound[12792]: [12792:0] info: server stats for thread 0: 1 queries, 0 answers from cache, 1 recursions, 0 prefetch, 0 rejected by ip ratelimiting
	<daemon.info> unbound[12792]: [12792:0] info: server stats for thread 0: requestlist max 0 avg 0 exceeded 0 jostled 0
	<daemon.info> unbound[12792]: [12792:0] info: average recursion processing time 1.667362 sec
	<daemon.info> unbound[12792]: [12792:0] info: histogram of recursion processing times
	<daemon.info> unbound[12792]: [12792:0] info: [25%]=0 median[50%]=0 [75%]=0
		<daemon.info> unbound[12792]: [12792:0] info: lower(secs) upper(secs) recursions
	<daemon.info> unbound[12792]: [12792:0] info:    0.032768    0.065536 1
	<daemon.info> unbound[12792]: [12792:0] info:    0.262144    0.524288 2
	<daemon.info> unbound[12792]: [12792:0] info:    0.524288    1.000000 1
	<daemon.info> unbound[12792]: [12792:0] info:    4.000000    8.000000 1
	…

This takes a very loooong time (recent FreeBSD 12.1-STABLE, unbound version 1.10.1). Sometimes > 10 minutes.

How can I tell unbound to forget about that, and just stop right away by omitting those unwanted statistics?

Thanks and regards,
