We are using bind as a recursive dns server in our college. It is working fine.
Now we need to make a report regarding QPS, NXDOMAIN, FORMAT ERROR,
Server Failure, Name Error, Not Implemented, Refused queries comes to
our recursive DNS SERVER.
For this we use named_statistics file which gives all information
regarding our requirement.
But when look in to named_statistics file, It shows below output,
+++ Statistics Dump +++ (1356630443)
++ Name Server Statistics ++
4 IPv4 requests received
2 requests with EDNS(0) received
4 responses sent
2 responses with EDNS(0) sent
3 queries resulted in successful answer
4 queries resulted in non authoritative answer
1 queries resulted in NXDOMAIN
4 queries caused recursion
++ Zone Maintenance Statistics ++
++ Resolver Statistics ++
67 IPv4 queries sent
66 IPv4 responses received
3 NXDOMAIN received
8 FORMERR received
8 EDNS(0) query failures
10 query retries
2 query timeouts
12 IPv4 NS address fetches
21 DNSSEC validation attempted
16 DNSSEC validation succeeded
5 DNSSEC NX validation succeeded
6 queries with RTT 10-100ms
60 queries with RTT 100-500ms
While making report regarding our requirement, do we need to consider
Resolver Statistics or Name Server Statistics values ?
What will be difference between view : default and view _bind ?
Because when we look on NXDOMAIN values view: default shows 3 and
view: _bind shows 1, so as we are playing recursive dns server role in
network, from which we consider correct value for our requirement ?
if is there any nice document to understand this statistics, please share it.
