That depends entirely on what you mean by "a true queries per second stat".
Incoming queries are those sent by clients to the nameserver. Outgoing
queries are those the nameserver sent to other nameservers, in the course
of resolving the client queries, or for some other reason.
Or, from a performance standpoint should I only be concerned
about incoming queries? In this case:
+++ Statistics Dump +++ (1317224125)
++ Incoming Requests ++
43128 QUERY
++ Incoming Queries ++
28719 A
381 NS
22 CNAME
16 SOA
811 PTR
5269 MX
629 TXT
6721 AAAA
15 SRV
141 A6
2 DS
266 SPF
136 ANY
The "incoming requests" (43128) number is the total number of
requests/queries.
Just because in this case all the requests were queries. In general
there might be other types of request - e.g. IQUERY, NOTIFY, UPDATE.
The breakdown of queries by type is just that - the numbers in your
example do add up to 43128.
So to get a TOTAL queries per second on all types of
queries, I would perform calculations on this number, correct?
If you are interested in queries per second sent to the nameserver,
yes. (This doesn't of course necessarily mean queries successfully
responded to from the client's point of view.)
