Hello.
I trying to use MRTG to create graphs for every client IP on my gateway, but for some strange reason it creates png and html files, but doesnt get info from script.But it creates graphs and get info from interface script.
System is Debian Etch
This is ls /var/www/mrtg/ -al

Here is mrtg.cfg
PHP Code:

This is script for interface graph, mrtg gets everything(traffic,hostname and uptime) from it without problem
PHP Code:
#!/bin/bash
/sbin/ip -s link show dev $1|grep -A 1 RX|tail -n1 |awk '{print $1}'
/sbin/ip -s link show dev $1|grep -A 1 TX|tail -n1 |awk '{print $1}'
echo `uptime | awk '{ print $3,$4,$5 }' | sed 's/,//g'`
echo `hostname`
Script output :
PHP Code:
deb:~# /usr/local/bin/ifstat.sh eth0

Here is script for IP graph, mrtg only create files, but dont put any data in them
PHP Code:
#!/bin/sh
iptables -L traffic_in -vnx | awk '{if (int($1)!=0) print $2}'
iptables -L traffic_out -vnx | awk '{if (int($1)!=0) print $2}'
echo `uptime | awk '{ print $3,$4,$5 }' | sed 's/,//g'`
echo `hostname`
Script output :
PHP Code:
deb:~# /usr/local/bin/checktraffic.sh

Not even a word in mrtg.log about wrong paths ,errors ...nothing useful for debuging
Please give me an idea where to search my mistake.
SOLVED:
I dont know why, but when mrtg runs as daemon errors(or at least part of them) doesn't go in log file.So I started mrtg as cronjob and I see where is the problem
PHP Code:
2009-02-20 16:50:02: ERROR: Target[192.168.168.11][_OUT_] ' $target->[1]{$mode} ' did not eval into defined data
/usr/local/bin/checktraffic.sh: line 2: iptables: command not found
/usr/local/bin/checktraffic.sh: line 3: iptables: command not found
In checktraffic iptables was described without full path, so when I change
iptables -L traffic_in -vnx | awk '{if (int($1)!=0) print $2}'
to
/sbin/iptables -L traffic_in -vnx | awk '{if (int($1)!=0) print $2}'
problem was solved.
