[mrtg] Re: here's the DNS stats script

[Craig Allen]

I have installed the script but my graphs don't get updated, they remain on
0.

If i run the script manually i get results and if i wait a while and run the
script again the results are identical to the first time i ran the script
and i know that there has been dns queries between the times i ran the
script.

Any ideas.

Regards

Craig

Here is the script I use, since many have asked for it. It uses the command
"ndc stats" which is included with BIND. You'll need to figure out the
paths for the command on your system and the path to where it writes its
file out. 

DISCLAIMER: this script is a dumb little thing, but it works. I will not be
held responsible if you can't get it to work on your machine or if it
causes problems or does not behave the way you expect. Good Luck.

You can call it from MRTG using a config like this:

Target[dnsstats]: `rsh machine_name /path/to/script`
MaxBytes[dnsstats]: 15000
AbsMax[dnsstats]: 1500000
Options[dnsstats]: gauge, nopercent
Title[dnsstats]: machine_name DNS Statistics
WithPeak[dnsstats]: dwmy
YLegend[dnsstats]: Queries
ShortLegend[dnsstats]: Queries
LegendI[dnsstats]:  Queries:
PageTop[dnsstats]: <H1>DNS Stats Report for machine.domain.com</H1>

Or you can figure out a different way to call it if you don't want to rsh
it. The 'ndc stats' command has to be run as root, i believe, so you may
want to modify the script to save output to a file if security between the
two machines is a big concern.

Anyway, here is the script

#!/usr/bin/perl

`/usr/sbin/ndc stats`;

@stats = `head -n 25 /etc/DNS/named.stats`;


foreach $line (@stats) {
$queries = "";
($queries,$rest) = split(" ",$line) if ($line =~ "queries");
$totalqueries = $totalqueries + $queries;
}

print "$totalqueries\n$totalqueries\n\n\n";

exit;


Good Luck to all,

Adam
