[mrtg] FW: mrtg and bind 9

[Ripley, Scott]

Steve,

I tried that stat.pl extension, but could never get it to work correctly.
And we're not running BIND9 (not that brave) so I can't comment on the
format of the stats file.

But it is easy enough to gather your own stats using that named.stats file.
Write a script to parse the data you want out of the stats dump, then call
that script from MRTG. 

We gather numbers on ALL, PTR, CNAME,MX and ANY using this script. This
script has options for each set of data (since MRTG can only take two
numbers at a time) so, for example:

Target[dns_all]: `/path/to/script/getstats all`
....
Target[dns_cname]: `/path/to/script/getstats cname`

The tricky part for us, since MRTG doesn't run on the DNS servers
themselves, was getting the data to the MRTG machine. One script on each DNS
servers parses new statistics from the stats dump, and the MRTG machine
gathers those files via an expect script and tftp.

The getstats script then uses those files to give MRTG new numbers. It's
sounds more complicated than it is, but having those DNS stats has been a
real boon for us, so the effort has been worth it.

I hope my confusing explanation has been of some help.

Is anyone mapping dns statistics to monitor bind 9 named.stats file?
According to the docs the format is similar but no identical to bind 8.
Here is a URL showing what the format should be.  I'm not a programmer so
I'm not even going to attempt to modify the stat.pl but hoping some one that
is into that has already done the dirty work.

Thanks,
