BIND Statistics?

We are migrating all of our DNS zones to our new GTM appliances (1600). Eventually we will start using Wide IPs, but we are not ready yet. I still want to be able to get stats on how many hits our zones are getting. F5 support told me they do not support any stats for the BIND engine. I was kinda surprised at this since F5 sales made it seem pretty common to use these as full DNS servers. Does anyone know how I can get stats on things like number of queries per zone, per record etc?

  • They might not support the BIND stats from a PD or troubleshooting standpoint, but it still works just fine. Just configure named.conf as you would on a normal BIND server. I did a quick test adding:

    zone-statistics yes;

    to my zone and then kicked off an rndc stats at the command line, which generated named.stats as expected in /var/named/config/namedb:

    [root@golgotha:Active] namedb  cat named.stats

  • I am not used to configuring BIND directly. I have used it in the past through a GUI front end. Can you give me some pointers on how to configure BIND for this logging?
  • I should clarify that you only need to enable at the zone-specific level if you've disabled globally or are not configured globally. Configuring zone specifically just gives you flexibility, but if you want it all, just configure it globally in named.conf.
  • Thanks I got that to work. Now is there a way to break it down to list how many queries per record?
