Comment:

 At the moment, there are three counters for incoming requests:

 * auth.[zonename].request.v{4|6}: Total number of requests over IPv4/6
 * auth.[zonename].request.tcp: Total number of TCP requests.

 (The total number of UPD requests can be inferred from these counters.)
 Would it be better to alter the counters (and add another one) to:

 * auth.[zonename].request.udp{4|6}: Total number of UDP requests over
 IPv4/6
 * auth.[zonename].request.tcp{4|6}: Total number of TCP requests over
 IPv4/6.

 The totals of requests for V4 and V6, as well as the total number of UDP
 and TCP requests can be found, but in addition the counters give a more
 detailed breakdown.

 For the resolver, the counters resolver.rdtype.xxx (where xxx is a, ns, mx
 etc.) are described as the number of responses received.  Is that
 responses received from upstream servers, or should the description read
 "queries received"?

 In the resolver, the counters resolver.requestv4, resolver.requestv6 and
 resolver.reqtcp give the number of IPv4, IPv6 and TCP requests received.
 For the same reasons as above, would it be better to create four counters:
 resolver.reqtcp{4|6} and resolver.requdp{4|6}.

 resolver.qryrecursion.  Is this needed in BIND 10, given that the resolver
 and the authoritative server are now separate and so will have separate
 counters?
