Did you compile dnsdist yourself? If I try to install dnsdist on
13.1-RELEASE-p6 I only get 1.7.3:
# pkg install dnsdist
New packages to be INSTALLED:
# pkg install dnsdist-1.8.0
pkg: No packages available to install matching 'dnsdist-1.8.0' have
been found in the repositories
A quick test with a self-compiled 1.8.0 dnsdist shows a non-zero sum
for me, so I'm confused what's goiong on.
prometheus output after a few queries to a UDP upstream:
# HELP dnsdist_latency Histogram of responses by latency (in milliseconds)
# TYPE dnsdist_latency histogram
