I want to log a sample of our DNS queries to dnsdist. We run dnsdist
1.3.3 under systemd.
I have tried:
I would expect this to log ~1/100 of our queries. But there's obviously
a bug in the docs for dnsdist because LogAction() always require at
least one argument. I couldn't find a good place to fix it and make a
pull request. Should I make a github issue?
So I tried to supply '' (the empty string) as filename, which should
make dnsdist log to stdout, but that only works with --verbose according
to the docs which then again logs everything, so not exactly what I wanted.
I also tried to specify 'unix:/dev/log' as file name but apparently
dnsdist don't want to log to a socket.
Ideally I just want dnsdist to log to stdout so systemd will pick up the
output, but how can that be done without the --verbose option?
