How to enable named/bind/DNS full logging? [closed]

Question

I am trying to find the perfect logging clause in named.conf that would help me enable full-level logs for named service. Can someone give an example here? My current clause is given below, but this generates very minimal logs.

 logging {      channel querylog{              file "/var/log/querylog";              severity debug 10;              print-category yes;              print-time yes;              print-severity yes;              };      category queries { querylog;};  };

I usually expand each log out into it's own channel and then to a separate log file, certainly makes things easier when you are trying to debug specific issues. So my logging section looks like the following:

logging {     channel default_file {         file "/var/log/named/default.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel general_file {         file "/var/log/named/general.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel database_file {         file "/var/log/named/database.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel security_file {         file "/var/log/named/security.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel config_file {         file "/var/log/named/config.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel resolver_file {         file "/var/log/named/resolver.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel xfer-in_file {         file "/var/log/named/xfer-in.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel xfer-out_file {         file "/var/log/named/xfer-out.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel notify_file {         file "/var/log/named/notify.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel client_file {         file "/var/log/named/client.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel unmatched_file {         file "/var/log/named/unmatched.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel queries_file {         file "/var/log/named/queries.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel network_file {         file "/var/log/named/network.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel update_file {         file "/var/log/named/update.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel dispatch_file {         file "/var/log/named/dispatch.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel dnssec_file {         file "/var/log/named/dnssec.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };     channel lame-servers_file {         file "/var/log/named/lame-servers.log" versions 3 size 5m;         severity dynamic;         print-time yes;     };      category default { default_file; };     category general { general_file; };     category database { database_file; };     category security { security_file; };     category config { config_file; };     category resolver { resolver_file; };     category xfer-in { xfer-in_file; };     category xfer-out { xfer-out_file; };     category notify { notify_file; };     category client { client_file; };     category unmatched { unmatched_file; };     category queries { queries_file; };     category network { network_file; };     category update { update_file; };     category dispatch { dispatch_file; };     category dnssec { dnssec_file; };     category lame-servers { lame-servers_file; }; }; 

Hope this helps.
