Hi,

I use the dnsload script with hobbit.

Here's a crontab entry :

*/5 *   * * *   root    /usr/local/hobbit/client/ext/bbdl-roll.sh >/dev/null 2>&1

I also modified bbdl-roll to change the location of tmp files, because
ext/ didn't look good to me :

in bbdl-roll.sh :

BB_EXT=/usr/local/hobbit/client/tmp

in bbdl-stats.sh, replace all "$BBHOME/ext" with "$BBHOME/tmp".

Wait a few cycles so the statistics initialize, and then add bbdl-stats
to clientlaunch.cfg.

For the server-side grapher, I use :

NCV_dnsload="Queryrate:GAUGE,*:NONE"

[dnsload]
        DEF:q=dnsload.rrd:Queryrate:AVERAGE
        TITLE DNS queries rate
        YAXIS queries/second
        -l 0
        AREA:q#00ff00:queries/sec
        GPRINT:q:LAST:%3.0lf
        GPRINT:q:MAX:max\: %3.0lf
        GPRINT:q:MIN:min\:%3.0lf
        GPRINT:q:AVERAGE:avg\:%3.0lf
