Hi,

I have  a problem for counting the total number of query DNS.
When I send 320 000 query (10 000 cname) by QueryPerf, I lost 59 query
in the XML file  client_total

My conf file :

dataset qname_qtype dns Qname:qname Qtype:qtype queries-only;
dataset qname_client dns Qname:qname Client:client_subnet queries-only
max-cells=50;
dataset qtype_total dns All:null Qtype:qtype queries-only;
dataset client_total dns All:null Client:client_subnet queries-only
max-cells=50;

I think the number of CNAME is too high but why I have this problem ?

Thank you

Stan
