Hi!!
I am setting up MRTG to monitor TC Classes. I have created several scripts
regarding this issue.
Quote:
Script for creating individual Directory with IP addresses as the Directory
name mkdir.sh
Code:
#!/bin/bash #set -x FILE="/users/ids.ips" cat $FILE | while read ids do
ips=`echo $ids | awk '{print $1}'` mkdir /var/www/mrtg/$ips mkdir
/var/www/mrtg/$ips/images cp /var/www/mrtg/mrtg*.png /var/www/mrtg/$ips/images/
done Perl Script used to get values from TC class from a file containing output
of tc -s class show dev eth0 > class.eth0 rate.pl (Downloaded From Internet)
Code:
#!/usr/bin/perl # License: Are you joking? This is trivial... # USAGE: #
$ARGV[0] - infile # $ARGV[1] - inclassmark # use strict; use English; my
$foundclass = 0; my $classID; my $inbytes; open INFILE, $ARGV[0]; while
(<INFILE>) { if ((!$foundclass) && (/^class\s+cbq\s+(\d+:\d*)\s+/)) {
$classID = $1; if ($classID eq $ARGV[1]) { $foundclass = 42; }
} if ($foundclass && (/^\s+Sent\s+(\d+)\s+bytes/)) { $inbytes = $1;
last; } } close INFILE; print "$inbytes\n";
Script for creating individual scripts for the use of CFG's for individual IP's
make.sh
Code:
#!/bin/bash NETWORK="eth0" file="/users/ids.ips" dir="/files/stat/scripts"
stat="/files/stat/stat.$NETWORK" rate="/files/stat/rate.pl" awk="/usr/bin/awk"
rm -fr $dir mkdir $dir rm -fr $dir/*.sh cat $file | while read ids do ID=`echo
$ids | $awk '{print $2}'` IP=`echo $ids | $awk '{print $1}'` touch $dir/$IP.sh
echo -e "#!/bin/bash\n\n" >$dir/$IP.sh echo -e "/usr/bin/perl $rate $stat
10:$ID" >> $dir/$IP.sh done Script for creating individual CFG's to used for
MRTG make.cfg
Code:
#!/bin/bash #set -x idfile="/users/ids.ips" cfgdir="/files/stat/cfgs"
shdir="/files/stat/scripts" workdir="/var/www/mrtg" awk="/usr/bin/awk" rm -fr
$cfgdir mkdir $cfgdir chmod 777 -R $shdir/ cat $idfile | while read ids do
ID=`echo $ids | $awk '{print $2}'` IP=`echo $ids | $awk '{print $1}'` touch
$cfgdir/$IP.cfg echo "EnableIPv6: no" > $cfgdir/$IP.cfg echo "Workdir:
/var/www/mrtg/$IP" >> $cfgdir/$IP.cfg echo "Options[_]: growright, unknaszero"
>> $cfgdir/$IP.cfg echo "Target[tc.class]: \`$shdir/$IP.sh\`" >>
$cfgdir/$IP.cfg echo "MaxBytes[tc.class]: 1000000000" >> $cfgdir/$IP.cfg echo
"Title[tc.class]: TC Class $ID, IP Address $IP, Graphs" >> $cfgdir/$IP.cfg echo
"Options[tc.class]: growright, nopercent" >> $cfgdir/$IP.cfg echo
"PageTop[tc.class]: <H1>TC Class $ID, IP Address $IP, Graphs</H1>" >>
$cfgdir/$IP.cfg echo "YLegend[tc.class]: Bytes/second" >> $cfgdir/$IP.cfg echo
"ShortLegend[tc.class]: Bytes/s" >> $cfgdir/$IP.cfg done Script created to make
index.html by the use of indexmake from CFG's index.sh
Code:
#!/bin/bash #set -x file="/users/ids.ips" cfgdir="/files/stat/cfgs"
workdir="/var/www/mrtg" cat $file | while read ids do IP=`echo $ids | awk
'{print $1}'` indexmaker $cfgdir/$IP.cfg > $workdir/$IP/index.html done Now
after running all these script, all scripts work fine with our any error. When
i run
Code:
env LANG=C /usr/bin/mrtg /files/stat/cfgs/*.cfg i get following erroe
Quote:
WARNING: Problem with External get '/files/stat/scripts/172.16.10.10.sh':
Expected a Number for 'out' but nothing' ERROR: Target[tc.class][_OUT_] '
$target->[0]{$mode} ' did not eval into defined data
Please let me know how can i remove this error and make my MRTG work.
