I don't think we have a way to log only these, unfortunately :-/ If you 
have the dnsdist console set up, you can use grepq('1000ms') to look at 
all queries that took more than 1 second, which is usually indicative of 
a problem, or even grepq('2000ms'), as dnsdist records timeouts with a 
very high response time.
