Hi,
I am trying to get Ipv4 query rate for our DNS server. I am taking 2
snapshots with a delay of 60 seconds between these snapshots.
curl <dns-server>:<port> > /tmp/snapshot1.xml
sleep 60
curl <dns-server>:<port> > /tmp/snapshot2.xml
I am calculating queryrate as below
query_rate = (Queryv4_value2 - Queryv4_value1) / (current_time2 - current_time1)
where Queryv4 values are the values extracted from XML file and current_time
are the values from XML files ( and I am converting this to epoch to get number
of seconds between these snapshots which is typically 60 seconds)
<current-time>2012-08-07T21:47:36Z</current-time>
Here is the issue:
I am sending approx 200 'A' queries to the DNS server and my above calculation
is showing a value of 2 queries-per-second.
What am I doing wrong?
thanks
Blr
