named.stats is empty

Hello,

I am trying to get some statistics from my DNS server, but each time I run [cmd=]rndc stats[/cmd] the file which should contain stats on the number of DNS queries is empty. My system is running FreeBSD 6.3-RELEASE-p8 and I am running BIND 9.3.4-P1.

I did some research and found some threads indicating that the stats file was might be owned by the wrong user, so I ran chown and both files are now owned by the user bind.

I have configured the following in named.conf:

Code: 
options {
        directory       "/etc/namedb";
        pid-file        "/var/run/named/pid";
        dump-file       "/var/dump/named_dump.db";
[B][I]  statistics-file "/var/stats/named.stats";
        zone-statistics yes;[/I][/B]

Based on this, the file should be located at /var/stats/named.stats, but this file is 0 Bytes. There is a stats file being created at /var/named/var/stats/named.stats, but it does not seem to contain the data I'm looking for.

Output from /var/named/var/stats/named.stats:

Code: 
+++ Statistics Dump +++ (1257971773)

+++ Statistics Dump +++ (1297895725)
The file /var/stats/named.stats should have stats like the ones listed below, but it's empty and the time stamp does not change after I run [cmd=]rndc stats[/cmd] Do I need to upgrade my version of bind to get the statistics I’m looking for?

Output found from other named.stats files found on the web:

If you simply remove that statistics-file line and restart named, running [cmd=]rndc stats[/cmd] will simply dump it in /etc/namedb/named.stats (a.k.a. /var/named/etc/namedb/named.stats).

You should see something like this:

Code: 
# service named restart && rndc stats && cat /var/named/etc/namedb/named.stats
Stopping named.
Starting named.

Hello,

No, to get this statistics you have to enable category queries to be logged in some logfile (which is not recommended for heavy loaded DNS server), and then install /usr/ports/net/bindgraph.

For example you can place in the logging directive:

Code: 
channel audit_log {
file "named.log";
print-time yes;
severity debug;
    };
category queries { audit_log; };

Also you can set the maximum size of the log filename, if you don't use some external tool for rotating.
