DNS monitoring with MRTG - script is funny

[StarTAC]

hi all..

i am running this script to gather stats for my MRTG MIB so i know my DNS performance.. i got it off the web, so i am guessing some of u use it too..

#!/bin/sh
#
# bindstats -- dump bind stats for MRTG
#

#Verify location!
STATSFILE="/var/lib/named/named.stats";

#Clear stats file first...
cat /dev/null > $STATSFILE;

#Dump stats...
# Use ndc for BIND8, rndc for BIND9
/usr/sbin/rndc stats

cat $STATSFILE;


it gathers stats fine and feeds them to MRTG.. my only problem is that MRTG caps at 60 requests per minute, for all my name servers..

my Maxbytes MIB is set to 32000 and AbsMax set to 64000 .. why are the records capping out at 60 only, and yet i am sure there could be a variation, upward mostly, as it's not dropping..

all help appreciated..

You probably have the reporting boundaries set too narrowly in the actual MRTG config for the display. There is nothing in this script you've shown that limits anything. Check your X and Y axis limits in the MRTG profile for your report.

well, i thought this was the case and i adjusted the axes accordingly, but what i realised was that the actual counters were fixed at 60, never changing..

i think if the problem was with the png, then at least the values below it would change some.. u think..?..

all help appreciated..
