Hi All i am running Bind version 9.8.1 as an Authoritative Name server. From the rndc.stats , i observe that there are some query failures happening in the server. I am trying to get a detailed information of this query failures, but the current logging options is not allowing me to get a detailed report on the reason of failure. I tried enabling detailed logs, but that is also not providing me which all queries failed with NXDOMAIN , SERVFAIL....etc.
