Get Trace of Server Recursive Queries

Dear Bind Users,
Hello,

I was wondering if it is possible to get the full log of individual
recursive queries that Bind server makes.
For example step by step from root servers to the final name server.
I am aware of "dig +trace" command but it is from users perspective, not
servers.
We may have some specific policies for some domains that users might not be
aware of, but we want to make sure that everything works as it is supposed
to, in the server.

Thanks in advance.

If this is for debugging, try `rndc trace 11`

Otherwise, have a look at dnstap, or use tcpdump.
