Is my DNS server working?

[SelbyGlenn]

Hi there,

Is there any way of telling how many queries a Name Server has had since its been up? I'm not interested at who's querying and I don't want to log everything as the logs will become huge. All I am after is the total number of hits since the server has been up. I am running BIND 9 on RH7.3.

Thanks in advance,

You might want to take a look at:

In your /etc/named.conf file add, in the 'options' section:

options {
...
zone-statistics yes;
host-statistics yes;
...
};

(of course the '...' means other stuff may be there).

You can also add the 'statistics-interval <seconds>;' options to have it automagically create statistics at even internvals. Statistics files will be placed in your 'directory <dirname>;' entry (also in the options stanza).

Now, you can force outputting of the statistics with a 'rndc' command. The command option is 'rndc stats'. If you just want host level stuff, just use the 'host-statistics' option, but I find zone statistics to be useful.

Anyhow, if you do run at even intervals (the 'statistics-interval' option), I highly suggest adding log maintenance under logrotate, such as an /etc/logrotate.d file similar to:

/var/log/named.log {
missingok
postrotate
/bin/kill -HUP `cat /var/named/named.pid 2> /dev/null` 2> /dev/null || true
endscript
}

/var/named/named.stats {
missingok
}


Hope this helps!
