■ Content of the question section for DNS query messages
■ Content of the answer section for DNS query messages
■ Number of queries this server sends
■ Number of queries this server has received
■ Number of DNS requests received over a UDP port
■ Number of DNS requests received over a TCP port
■ Number of full packets sent by the server
■ Number of packets written through by the server and back to the zone
