There are more scalable ways of doing this.  The "standards-compliant" 
way is dnstap:

You'll need to install a separate dnstap collector to receive the messages.

Note that powerDNS has a dependency on the "fstrm" library:

If you have an older version of fstrm then you can only log to a local 
unix domain socket (which may be fine, it just means running your dnstap 
collector on the same host).  A newer version is required if you want to 
log to a remote host over TCP.

I don't know about versions in RHEL/CentOS, but Ubuntu 18.04 has 
libfstrm0 version 0.3.0, and that only does unix domain sockets.
