Bind Statistics questions

[Emery]

Hello Nuno,

I don't know if you can reset the stats, but in my environment I had the 
need to check statistics to alert us to attacks and high abnormally high 
query numbers. In order to do this, I wrote shell scripts that check the 
current count and writes that value to a file. This is a rotating 
process with the each iteration writing the current value to a file and 
on the next cycle comparing the new value to the written value before 
writing the new value to the file. On each iteration, the new value is 
subtracted from the written value to get the actual 1 minute count.

I use this process for the query and recursive query counts and if they 
breach a specific level, an email is sent. We also use Sitescope 
monitoring to the values to get trending information. If the stats 
cannot be reset, this is an alternative that has worked for me.
