dns section of the
packetbeat.yml config file specifies configuration
options for the DNS protocol. The DNS protocol supports processing DNS messages
on TCP and UDP. Here is a sample configuration section for DNS:
packetbeat.protocols: - type: dns ports:  include_authorities: true include_additionals: true
Also see Common protocol options.
If this option is enabled, dns.authority fields (authority resource records) are added to DNS events. The default is false.
If this option is enabled, dns.additionals fields (additional resource records) are added to DNS events. The default is false.
