As I happen to know which OS you use, the CentOS 7 rpm is built with protobuf support but without FSTRM support. However, you can still use dnstap with this package. dnsdist supports two dnstap modes (FrameStream and raw dnstap over protobuf):

"Canonically, dnstap is sent over a FrameStream socket, either a local AF_UNIX (see newFrameStreamUnixLogger()) or a TCP/IP socket (see newFrameStreamTcpLogger()). As an extension, dnsdist can send raw dnstap protobuf messages over a newRemoteLogger()."

However, I'm no dnstap expert and cannot say what the advantages/disadvantages of either of these two dnstap modes are.
